Two generic ways to do the same thing... I'm not aware of any specific open solutions to do this, but it'd be rather trivial to do.
You could write a daily or weekly cron/jenkins job to scrape the previous time period's email from the archive looking for your keyworkds/combinations. Sending a batch digest with what it finds, if anything.
But personally, I'd Setup a specific email account to subscribe to the various security lists you're interested in. Add a simple automated script to parse the new emails for various keywords or combinations of keywords, when it finds a match forward that email on to you/your team. Just be sure to keep the keywords list updated with new products you're using.
You could even do this with a gmail account and custom rules, which is what I currently do, but I have setup an internal inbox in the past with a simple python script to forward emails that were of interest.
When you read()
the file, you may get a newline character '\n'
in your string. Try either
if UserInput.strip() == 'List contents':
or
if 'List contents' in UserInput:
Also note that your second file open
could also use with
:
with open('/Users/.../USER_INPUT.txt', 'w+') as UserInputFile: if UserInput.strip() == 'List contents': # or if s in f: UserInputFile.write("ls") else: print "Didn't work"
I think you missed a equal sign at:
Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + "" + l, null, null, null, null);
Change to:
Cursor c = ourDatabase.query(DATABASE_TABLE, column, KEY_ROWID + " = " + l, null, null, null, null);
You're storing the .Text
properties of the textboxes directly into the database, this doesn't work. The .Text
properties are String
s (i.e. simple text) and not typed as DateTime
instances. Do the conversion first, then it will work.
Do this for each date parameter:
Dim bookIssueDate As DateTime = DateTime.ParseExact( txtBookDateIssue.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture ) cmd.Parameters.Add( New OleDbParameter("@Date_Issue", bookIssueDate ) )
Note that this code will crash/fail if a user enters an invalid date, e.g. "64/48/9999", I suggest using DateTime.TryParse
or DateTime.TryParseExact
, but implementing that is an exercise for the reader.
The link you gave does actually describe the differences, but it's buried at the bottom of the page:
http://www.cplusplus.com/reference/cstdio/fopen/
Text files are files containing sequences of lines of text. Depending on the environment where the application runs, some special character conversion may occur in input/output operations in text mode to adapt them to a system-specific text file format. Although on some environments no conversions occur and both text files and binary files are treated the same way, using the appropriate mode improves portability.
The conversion could be to normalize \r\n
to \n
(or vice-versa), or maybe ignoring characters beyond 0x7F (a-la 'text mode' in FTP). Personally I'd open everything in binary-mode and use a good text-encoding library for dealing with text.
What you show looks like a mesh warp. That would be straightforward using OpenGL, but "straightforward OpenGL" is like straightforward rocket science.
I wrote an iOS app for my company called Face Dancerthat's able to do 60 fps mesh warp animations of video from the built-in camera using OpenGL, but it was a lot of work. (It does funhouse mirror type changes to faces - think "fat booth" live, plus lots of other effects.)
Your problem is that, if the user clicks cancel, operationType
is null and thus throws a NullPointerException. I would suggest that you move
if (operationType.equalsIgnoreCase("Q"))
to the beginning of the group of if statements, and then change it to
if(operationType==null||operationType.equalsIgnoreCase("Q")).
This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.
Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.
If I am not mistaken, it will be onunload event.
"Occurs when the application is about to be unloaded." - MSDN
The problem might be your split()
call. Try just split(" ")
without the square brackets.
The folder is part of the URL you set when you create request
: "ftp://www.contoso.com/test.htm"
. If you use "ftp://www.contoso.com/wibble/test.htm"
then the file will be uploaded to a folder named wibble
.
You may need to first use a request with Method = WebRequestMethods.Ftp.MakeDirectory
to make the wibble
folder if it doesn't already exist.
First of all, Applets are designed to be run from within the context of a browser (or applet viewer), they're not really designed to be added into other containers.
Technically, you can add a applet to a frame like any other component, but personally, I wouldn't. The applet is expecting a lot more information to be available to it in order to allow it to work fully.
Instead, I would move all of the "application" content to a separate component, like a JPanel
for example and simply move this between the applet or frame as required...
ps- You can use f.setLocationRelativeTo(null)
to center the window on the screen ;)
Updated
You need to go back to basics. Unless you absolutely must have one, avoid applets until you understand the basics of Swing, case in point...
Within the constructor of GalzyTable2
you are doing...
JApplet app = new JApplet(); add(app); app.init(); app.start();
...Why are you adding another applet to an applet??
Case in point...
Within the main
method, you are trying to add the instance of JFrame
to itself...
f.getContentPane().add(f, button2);
Instead, create yourself a class that extends from something like JPanel
, add your UI logical to this, using compound components if required.
Then, add this panel to whatever top level container you need.

The primary flag seems to only work for vagrant ssh

I suspect that the problem lies in the fact that you are calling your state setter immediately inside the function component body, which forces React to re-invoke your function again, with the same props, which ends up calling the state setter again, which triggers React to call your function again.... and so on.
const SingInContainer = ({ message, variant}) => {
const [open, setSnackBarState] = useState(false);
const handleClose = (reason) => {
if (reason === 'clickaway') {
return;
}
setSnackBarState(false)
};
if (variant) {
setSnackBarState(true); // HERE BE DRAGONS
}
return (
<div>
<SnackBar
open={open}
handleClose={handleClose}
variant={variant}
message={message}
/>
<SignInForm/>
</div>
)
}
Instead, I recommend you just conditionally set the default value for the state property using a ternary, so you end up with:
const SingInContainer = ({ message, variant}) => {
const [open, setSnackBarState] = useState(variant ? true : false);
// or useState(!!variant);
// or useState(Boolean(variant));
const handleClose = (reason) => {
if (reason === 'clickaway') {
return;
}
setSnackBarState(false)
};
return (
<div>
<SnackBar
open={open}
handleClose={handleClose}
variant={variant}
message={message}
/>
<SignInForm/>
</div>
)
}
See this CodeSandbox.io demo for a comprehensive demo of it working, plus the broken component you had, and you can toggle between the two.

You should just install python 3.6. I tried it and it worked. Just install that version of python and just do the normal download process (pip install pyaudio
).
I'm facing exactly same error when I'm trying to clone a repository on a brand new machine. I'm using Git bash as my Git client. When I ran Git's command to clone a repository it was not prompting me for user id and password which will be used for authentication. It was a fresh machine where not a single credential was cached by Windows credential manager.
As a last resort, I manually added my credentials in credentials manager.
Go to > Control Panel\User Accounts\Credential Manager
> Windows Credentials
Click Add a Windows credential
link and then Supply the details as shown in the form below and you're done:
I had put the details as below:
Internet or network address: <gitRepoServerNameOrIPAddress>
User Name: MyCompanysDomainName\MyUserName
Password: MyPassword
Next time you run any Git command targeting a repository set up on above address this manually created credential will be used.
It is also important if you have a git command line you close it and reopen it for changes to be applied.

If the mongoDB server is already installed and if you are unable to connect from a remote host then follow the below steps,
Login to your machine, open mongodb configuration file located at /etc/mongod.conf
and change the bindIp
field to specific ip / 0.0.0.0
, after that restart mongodb server.
sudo vi /etc/mongod.conf
The file should contain the following kind of content:
systemLog:
destination: file
path: "/var/log/mongodb/mongod.log"
logAppend: true
storage:
journal:
enabled: true
processManagement:
fork: true
net:
bindIp: 127.0.0.1 // change here to 0.0.0.0
port: 27017
setParameter:
enableLocalhostAuthBypass: false
Once you change the bindIp
, then you have to restart the mongodb, using the following command
sudo service mongod restart
Now you'll be able to connect to the mongodb server, from remote server.
After mounting on drive, use shutil.unpack_archive. It works with almost all archive formats (e.g., “zip”, “tar”, “gztar”, “bztar”, “xztar”) and it's simple:
import shutil
shutil.unpack_archive("filename", "path_to_extract")
It might be related to corruption in Angular Packages or incompatibility of packages.
Please follow the below steps to solve the issue.
Update
ASP.NET Boilerplate suggests here to use yarn because npm has some problems. It is slow and can not consistently resolve dependencies, yarn solves those problems and it is compatible to npm as well.
This error can also show up if there are parts in your string that json.loads()
does not recognize. An in this example string, an error will be raised at character 27 (char 27)
.
string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""
My solution to this would be to use the string.replace()
to convert these items to a string:
import json
string = """[{"Item1": "One", "Item2": False}, {"Item3": "Three"}]"""
string = string.replace("False", '"False"')
dict_list = json.loads(string)
Many people have given a fix, so I'll talk about the source of the problem.
According to the exception log:

Try using anaconda. I had the same error. One lone option was to build tensorflow from source which took long time. I tried using conda and it worked.

Then, it worked.
There are two ways to do it.
In the method that opens the dialog, pass in the following configuration option disableClose
as the second parameter in MatDialog#open()
and set it to true
:
export class AppComponent {
constructor(private dialog: MatDialog){}
openDialog() {
this.dialog.open(DialogComponent, { disableClose: true });
}
}
Alternatively, do it in the dialog component itself.
export class DialogComponent {
constructor(private dialogRef: MatDialogRef<DialogComponent>){
dialogRef.disableClose = true;
}
}
Here's what you're looking for:
And here's a Stackblitz demo
Here's some other use cases and code snippets of how to implement them.
As what @MarcBrazeau said in the comment below my answer, you can allow the esc key to close the modal but still disallow clicking outside the modal. Use this code on your dialog component:
import { Component, OnInit, HostListener } from '@angular/core';
import { MatDialogRef } from '@angular/material';
@Component({
selector: 'app-third-dialog',
templateUrl: './third-dialog.component.html'
})
export class ThirdDialogComponent {
constructor(private dialogRef: MatDialogRef<ThirdDialogComponent>) {
}
@HostListener('window:keyup.esc') onKeyUp() {
this.dialogRef.close();
}
}
P.S. This is an answer which originated from this answer, where the demo was based on this answer.
To prevent the esc key from closing the dialog but allow clicking on the backdrop to close, I've adapted Marc's answer, as well as using MatDialogRef#backdropClick
to listen for click events to the backdrop.
Initially, the dialog will have the configuration option disableClose
set as true
. This ensures that the esc
keypress, as well as clicking on the backdrop will not cause the dialog to close.
Afterwards, subscribe to the MatDialogRef#backdropClick
method (which emits when the backdrop gets clicked and returns as a MouseEvent
).
Anyways, enough technical talk. Here's the code:
openDialog() {
let dialogRef = this.dialog.open(DialogComponent, { disableClose: true });
/*
Subscribe to events emitted when the backdrop is clicked
NOTE: Since we won't actually be using the `MouseEvent` event, we'll just use an underscore here
See https://stackoverflow.com/a/41086381 for more info
*/
dialogRef.backdropClick().subscribe(() => {
// Close the dialog
dialogRef.close();
})
// ...
}
Alternatively, this can be done in the dialog component:
export class DialogComponent {
constructor(private dialogRef: MatDialogRef<DialogComponent>) {
dialogRef.disableClose = true;
/*
Subscribe to events emitted when the backdrop is clicked
NOTE: Since we won't actually be using the `MouseEvent` event, we'll just use an underscore here
See https://stackoverflow.com/a/41086381 for more info
*/
dialogRef.backdropClick().subscribe(() => {
// Close the dialog
dialogRef.close();
})
}
}
Trigger a change detection by using ChangeDetectorRef
in the refresh()
method
just after receiving the new data, inject ChangeDetectorRef in the constructor and use detectChanges like this:
import { Component, OnInit, ChangeDetectorRef } from '@angular/core';
import { LanguageModel, LANGUAGE_DATA } from '../../../../models/language.model';
import { LanguageAddComponent } from './language-add/language-add.component';
import { AuthService } from '../../../../services/auth.service';
import { LanguageDataSource } from './language-data-source';
import { LevelbarComponent } from '../../../../directives/levelbar/levelbar.component';
import { DataSource } from '@angular/cdk/collections';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/of';
import { MatSnackBar, MatDialog } from '@angular/material';
@Component({
selector: 'app-language',
templateUrl: './language.component.html',
styleUrls: ['./language.component.scss']
})
export class LanguageComponent implements OnInit {
displayedColumns = ['name', 'native', 'code', 'level'];
teachDS: any;
user: any;
constructor(private authService: AuthService, private dialog: MatDialog,
private changeDetectorRefs: ChangeDetectorRef) { }
ngOnInit() {
this.refresh();
}
add() {
this.dialog.open(LanguageAddComponent, {
data: { user: this.user },
}).afterClosed().subscribe(result => {
this.refresh();
});
}
refresh() {
this.authService.getAuthenticatedUser().subscribe((res) => {
this.user = res;
this.teachDS = new LanguageDataSource(this.user.profile.languages.teach);
this.changeDetectorRefs.detectChanges();
});
}
}
If you already installed "MongoDB", if you accidentally exit from the MongoDB server, then "restart your system".
This method solved me...
[On Windows only]
And also another method is there:
press:
Windows + R
type:
services.msc
and click "ok", it opens "services" window, and then search for "MongoDB Server" in the list. After you find "MongoDB Server", right-click and choose "start" from the pop-up menu.
The MongoDb Server will start running.
Hope it works!!
The pdf2image library can be used.
You can install it simply using,
pip install pdf2image
Once installed you can use following code to get images.
from pdf2image import convert_from_path
pages = convert_from_path('pdf_file', 500)
Saving pages in jpeg format
for page in pages:
page.save('out.jpg', 'JPEG')
Edit: the Github repo pdf2image also mentions that it uses pdftoppm
and that it requires other installations:
pdftoppm is the piece of software that does the actual magic. It is distributed as part of a greater package called poppler. Windows users will have to install poppler for Windows. Mac users will have to install poppler for Mac. Linux users will have pdftoppm pre-installed with the distro (Tested on Ubuntu and Archlinux) if it's not, run
sudo apt install poppler-utils
.
You can install the latest version under Windows using anaconda by doing:
conda install -c conda-forge poppler
note: Windows versions upto 0.67 are available at http://blog.alivate.com.au/poppler-windows/ but note that 0.68 was released in Aug 2018 so you'll not be getting the latest features or bug fixes.
Just to add another piece of info to this for anyone like me who happens along that just has a single application.
I had my application set up with the main app.module.ts and I had routing with the routing module in it's own folder under the main application. I went through and did some 'cleaning up' since I had a few other things that needed to be organized better. One thing I did was move the routing.module.ts to the root folder; since it was the only file in the folder I figured it didn't need it's own folder.
This worked fine at first but next time I tried to generate a new component (some time later, through the WebStorm IDE) it failed with this message. After reading through this I tried putting the routing module back into a separate folder and it worked again.
So note of warning to others, don't move the routing module into your root folder! I'm sure there are other ways to deal with this too but I'm happy with it in it's own folder for now and using the IDE generator like I was previously.
Well, what I do on every project is a mix of the options above.
First, add the jsr310 dependency:
<dependency>
<groupId>com.fasterxml.jackson.datatype</groupId>
<artifactId>jackson-datatype-jsr310</artifactId>
</dependency>
Important detail: put this dependency on the top of your depedencies list. I already see a project where the Localdate error persists even with this dependency on the pom.xml. But changing the order of the depedency the error was gone.
On your /src/main/resources/application.yml
file, setup the write-dates-as-timestamps
property:
spring:
jackson:
serialization:
write-dates-as-timestamps: false
And create a ObjectMapper
bean as this:
@Configuration
public class WebConfigurer {
@Bean
@Primary
public ObjectMapper objectMapper(Jackson2ObjectMapperBuilder builder) {
ObjectMapper objectMapper = builder.build();
objectMapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
return objectMapper;
}
}
Following this configuration, the conversion always work on Spring Boot 1.5.x without any error.
Working with Spring AMQP, pay attention if you have a new instance of Jackson2JsonMessageConverter
(common thing when creating a SimpleRabbitListenerContainerFactory
). You need to pass the ObjectMapper
bean to it, like:
Jackson2JsonMessageConverter converter = new Jackson2JsonMessageConverter(objectMapper);
Otherwise, you will receive the same error.
Check your routes/web.php and routes/api.php
Laravel comes with default route closure in routes/web.php:
Route::get('/', function () {
return view('welcome');
});
and routes/api.php
Route::middleware('auth:api')->get('/user', function (Request $request) {
return $request->user();
});
if you remove that then try again to clear route cache.
I faced the same problem. Found the fix here.

Run your pip installation command again. If everything works fine, its good. Or you might face the following error like me:
Finished generating code
LINK : fatal error LNK1158: cannot run 'rc.exe'
error: command 'C:\\Program Files (x86)\\Microsoft Visual Studio 14.0\\VC\\BIN\\x86_amd64\\link.exe' failed with exit status 1158
Found the fix for the above problem here: Visual Studio can't build due to rc.exe
That basically says
Add this to your PATH environment variables:
C:\Program Files (x86)\Windows Kits\8.1\bin\x86
Copy these files:
rc.exe
rcdll.dll
From
C:\Program Files (x86)\Windows Kits\8.1\bin\x86
To
C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\bin
It works like a charm
This will let you read, write and create the file if it don't exist:
f = open('filename.txt','a+')
f = open('filename.txt','r+')
Often used commands:
f.readline() #Read next line
f.seek(0) #Jump to beginning
f.read(0) #Read all file
f.write('test text') #Write 'test text' to file
f.close() #Close file
You can try this it will help for you.You can't get path from WhatsApp directly.If you need an file path first copy file and send new file path. Using the code below
public static String getFilePathFromURI(Context context, Uri contentUri) {
String fileName = getFileName(contentUri);
if (!TextUtils.isEmpty(fileName)) {
File copyFile = new File(TEMP_DIR_PATH + fileName+".jpg");
copy(context, contentUri, copyFile);
return copyFile.getAbsolutePath();
}
return null;
}
public static String getFileName(Uri uri) {
if (uri == null) return null;
String fileName = null;
String path = uri.getPath();
int cut = path.lastIndexOf('/');
if (cut != -1) {
fileName = path.substring(cut + 1);
}
return fileName;
}
public static void copy(Context context, Uri srcUri, File dstFile) {
try {
InputStream inputStream = context.getContentResolver().openInputStream(srcUri);
if (inputStream == null) return;
OutputStream outputStream = new FileOutputStream(dstFile);
IOUtils.copy(inputStream, outputStream);
inputStream.close();
outputStream.close();
} catch (IOException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
Then IOUtils class is like below
public class IOUtils {
private static final int BUFFER_SIZE = 1024 * 2;
private IOUtils() {
// Utility class.
}
public static int copy(InputStream input, OutputStream output) throws Exception, IOException {
byte[] buffer = new byte[BUFFER_SIZE];
BufferedInputStream in = new BufferedInputStream(input, BUFFER_SIZE);
BufferedOutputStream out = new BufferedOutputStream(output, BUFFER_SIZE);
int count = 0, n = 0;
try {
while ((n = in.read(buffer, 0, BUFFER_SIZE)) != -1) {
out.write(buffer, 0, n);
count += n;
}
out.flush();
} finally {
try {
out.close();
} catch (IOException e) {
Log.e(e.getMessage(), e.toString());
}
try {
in.close();
} catch (IOException e) {
Log.e(e.getMessage(), e.toString());
}
}
return count;
}
}
We dont need redux-persist we can simply use redux for persistance.
react-redux + AsyncStorage = redux-persist
so inside createsotre file simply add these lines
store.subscribe(async()=> await AsyncStorage.setItem("store", JSON.stringify(store.getState())))
this will update the AsyncStorage whenever there are some changes in the redux store.
Then load the json converted store. when ever the app loads. and set the store again.
Because redux-persist creates issues when using wix react-native-navigation. If that's the case then I prefer to use simple redux with above subscriber function
I think it has to do with your second element in storbinary
. You are trying to open file
, but it is already a pointer to the file you opened in line file = open(local_path,'rb')
. So, try to use ftp.storbinary("STOR " + i, file)
.
I added yellow highlighted package and now my view page is accessible. in eclipse when we deploy our war it only deploy those stuff mention in the deployment assessment.
We set Deployment Assessment from right click on project --> Properties --> Apply and Close....
There's no casting in javascript, so you cannot throw if "casting fails".
Typescript supports casting but that's only for compilation time, and you can do it like this:
const toDo = <IToDoDto> req.body;
// or
const toDo = req.body as IToDoDto;
You can check at runtime if the value is valid and if not throw an error, i.e.:
function isToDoDto(obj: any): obj is IToDoDto {
return typeof obj.description === "string" && typeof obj.status === "boolean";
}
@Post()
addToDo(@Response() res, @Request() req) {
if (!isToDoDto(req.body)) {
throw new Error("invalid request");
}
const toDo = req.body as IToDoDto;
this.toDoService.addToDo(toDo);
return res.status(HttpStatus.CREATED).end();
}
As @huyz pointed out, there's no need for the type assertion because isToDoDto
is a type guard, so this should be enough:
if (!isToDoDto(req.body)) {
throw new Error("invalid request");
}
this.toDoService.addToDo(req.body);
You shouldn't use ${varName}
when you're outside of strings, you should just use varName
. Inside strings you use it like this; echo "this is a string ${someVariable}";
. Infact you can place an general java expression inside of ${...}
; echo "this is a string ${func(arg1, arg2)}
.
I had the same error, but in my case, it was because I had too many containers running (about 220).
Check Java versions That was a problem for me. IDE (Intellij in my case) could launch without the problem, but when I tried to run war
inside tomcat docker image app didn't work. The reason was docker image had a different (lower) version compare to the development environment. There were no errors messages indicating any of this.
Problem solved, I've not added the index.html. Which is point out in the web.xml
Note: a project may have more than one web.xml file.
if there are another web.xml in
src/main/webapp/WEB-INF
Then you might need to add another index (this time index.jsp) to
src/main/webapp/WEB-INF/pages/
According to @Shovalt's answer, but in short:
Alternatively you could use the following lines of code
from sklearn.metrics import f1_score
metrics.f1_score(y_test, y_pred, labels=np.unique(y_pred))
This should remove your warning and give you the result you wanted, because it no longer considers the difference between the sets, by using the unique mode.
When you first read the body, you have to store it so once you're done with it, you can set a new io.ReadCloser
as the request body constructed from the original data. So when you advance in the chain, the next handler can read the same body.
One option is to read the whole body using ioutil.ReadAll()
, which gives you the body as a byte slice.
You may use bytes.NewBuffer()
to obtain an io.Reader
from a byte slice.
The last missing piece is to make the io.Reader
an io.ReadCloser
, because bytes.Buffer
does not have a Close()
method. For this you may use ioutil.NopCloser()
which wraps an io.Reader
, and returns an io.ReadCloser
, whose added Close()
method will be a no-op (does nothing).
Note that you may even modify the contents of the byte slice you use to create the "new" body. You have full control over it.
Care must be taken though, as there might be other HTTP fields like content-length and checksums which may become invalid if you modify only the data. If subsequent handlers check those, you would also need to modify those too!
If you also want to read the response body, then you have to wrap the http.ResponseWriter
you get, and pass the wrapper on the chain. This wrapper may cache the data sent out, which you can inspect either after, on on-the-fly (as the subsequent handlers write to it).
Here's a simple ResponseWriter
wrapper, which just caches the data, so it'll be available after the subsequent handler returns:
type MyResponseWriter struct {
http.ResponseWriter
buf *bytes.Buffer
}
func (mrw *MyResponseWriter) Write(p []byte) (int, error) {
return mrw.buf.Write(p)
}
Note that MyResponseWriter.Write()
just writes the data to a buffer. You may also choose to inspect it on-the-fly (in the Write()
method) and write the data immediately to the wrapped / embedded ResponseWriter
. You may even modify the data. You have full control.
Care must be taken again though, as the subsequent handlers may also send HTTP response headers related to the response data –such as length or checksums– which may also become invalid if you alter the response data.
Putting the pieces together, here's a full working example:
func loginmw(handler http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
body, err := ioutil.ReadAll(r.Body)
if err != nil {
log.Printf("Error reading body: %v", err)
http.Error(w, "can't read body", http.StatusBadRequest)
return
}
// Work / inspect body. You may even modify it!
// And now set a new body, which will simulate the same data we read:
r.Body = ioutil.NopCloser(bytes.NewBuffer(body))
// Create a response wrapper:
mrw := &MyResponseWriter{
ResponseWriter: w,
buf: &bytes.Buffer{},
}
// Call next handler, passing the response wrapper:
handler.ServeHTTP(mrw, r)
// Now inspect response, and finally send it out:
// (You can also modify it before sending it out!)
if _, err := io.Copy(w, mrw.buf); err != nil {
log.Printf("Failed to send out response: %v", err)
}
})
}
In my case, I target the test project to x64
Architecture and the test setting Architecture (test > Default Processor Architecture) changed was set to x86
. They didn't match.
After setting the test setting Architecture back to x64
and rebuilding, all tests were discovered again.
You can change the send line to this:
c.send(b'Thank you for connecting')
The b
makes it bytes instead.

A simple example for writing multiple data to excel at a time. And also when you want to append data to a sheet on a written excel file (closed excel file).
When it is your first time writing to an excel. (Writing "df1" and "df2" to "1st_sheet" and "2nd_sheet")
import pandas as pd
from openpyxl import load_workbook
df1 = pd.DataFrame([[1],[1]], columns=['a'])
df2 = pd.DataFrame([[2],[2]], columns=['b'])
df3 = pd.DataFrame([[3],[3]], columns=['c'])
excel_dir = "my/excel/dir"
with pd.ExcelWriter(excel_dir, engine='xlsxwriter') as writer:
df1.to_excel(writer, '1st_sheet')
df2.to_excel(writer, '2nd_sheet')
writer.save()
After you close your excel, but you wish to "append" data on the same excel file but another sheet, let's say "df3" to sheet name "3rd_sheet".
book = load_workbook(excel_dir)
with pd.ExcelWriter(excel_dir, engine='openpyxl') as writer:
writer.book = book
writer.sheets = dict((ws.title, ws) for ws in book.worksheets)
## Your dataframe to append.
df3.to_excel(writer, '3rd_sheet')
writer.save()
Be noted that excel format must not be xls, you may use xlsx one.
React Application: For me the issue was that after running npm install
had some errors.
I've went with the recommendation npm audit fix
. This operation broke my package.json
and package-lock.json
(changed version of packages and and structure of .json).
THE FIX WAS:
npm install
npm start
Hope this will be helpfull for someone.
There's a hook called useLocation in react-router v5, no need for HOC or other stuff, it's very succinctly and convenient.
import { useLocation } from 'react-router-dom';
const ExampleComponent: React.FC = () => {
const location = useLocation();
return (
<Router basename='/app'>
<main>
<AppBar handleMenuIcon={this.handleMenuIcon} title={location.pathname} />
</main>
</Router>
);
}
in accord with Laravel documentation, I create in app/Http/Controllers/Auth/LoginController.php the following method :
protected function redirectTo()
{
$user=Auth::user();
if($user->account_type == 1){
return '/admin';
}else{
return '/home';
}
}
to get the user information from my db I used "Illuminate\Support\Facades\Auth;".
The grammar of the language specifies that positional arguments appear before keyword or starred arguments in calls:
argument_list ::= positional_arguments ["," starred_and_keywords]
["," keywords_arguments]
| starred_and_keywords ["," keywords_arguments]
| keywords_arguments
Specifically, a keyword argument looks like this: tag='insider trading!'
while a positional argument looks like this: ..., exchange, ...
. The problem lies in that you appear to have copy/pasted the parameter list, and left some of the default values in place, which makes them look like keyword arguments rather than positional ones. This is fine, except that you then go back to using positional arguments, which is a syntax error.
Also, when an argument has a default value, such as price=None
, that means you don't have to provide it. If you don't provide it, it will use the default value instead.
To resolve this error, convert your later positional arguments into keyword arguments, or, if they have default values and you don't need to use them, simply don't specify them at all:
order_id = kite.order_place(self, exchange, tradingsymbol,
transaction_type, quantity)
# Fully positional:
order_id = kite.order_place(self, exchange, tradingsymbol, transaction_type, quantity, price, product, order_type, validity, disclosed_quantity, trigger_price, squareoff_value, stoploss_value, trailing_stoploss, variety, tag)
# Some positional, some keyword (all keywords at end):
order_id = kite.order_place(self, exchange, tradingsymbol,
transaction_type, quantity, tag='insider trading!')
Error Case:
var userListQuery = {
userId: {
$in: result
},
"isCameraAdded": true
}
( cameraInfo.findtext != "" ) ? searchQuery : userListQuery;
Output:
TypeError: (intermediate value)(intermediate value) is not a function
Fix: You are missing a semi-colon (;) to separate the expressions
userListQuery = {
userId: {
$in: result
},
"isCameraAdded": true
}; // Without a semi colon, the error is produced
( cameraInfo.findtext != "" ) ? searchQuery : userListQuery;
That happened once to me: I had a perfectly working Postman configuration, but then, without changing anything, even though I didn't inform the Content-Type
manually on Postman, it stopped working; following the answers to this question, I tried both disabling the header and letting Postman add it automatically, but neither options worked.
I ended up solving it by going to the Body
tab, change the param type from File
to Text
, then back to File
and then re-selecting the file to send; somehow, this made it work again. Smells like a Postman bug, in that specific case, maybe?
You are plotting all your images on one axis. What you want ist to get a handle for each axis individually and plot your images there. Like so:
fig = plt.figure()
ax1 = fig.add_subplot(2,2,1)
ax1.imshow(...)
ax2 = fig.add_subplot(2,2,2)
ax2.imshow(...)
ax3 = fig.add_subplot(2,2,3)
ax3.imshow(...)
ax4 = fig.add_subplot(2,2,4)
ax4.imshow(...)
For more info have a look here: http://matplotlib.org/examples/pylab_examples/subplots_demo.html
For complex layouts, you should consider using gridspec: http://matplotlib.org/users/gridspec.html
I ran this on MacOS /Applications/Python\ 3.6/Install\ Certificates.command
you can use:
df.plot(x='Date',y='adj_close')
Or you can set the index to be Date
beforehand, then it's easy to plot the column you want:
df.set_index('Date', inplace=True)
df['adj_close'].plot()
ticker
on itYou need to groupby before:
df.set_index('Date', inplace=True)
df.groupby('ticker')['adj_close'].plot(legend=True)
grouped = df.groupby('ticker')
ncols=2
nrows = int(np.ceil(grouped.ngroups/ncols))
fig, axes = plt.subplots(nrows=nrows, ncols=ncols, figsize=(12,4), sharey=True)
for (key, ax) in zip(grouped.groups.keys(), axes.flatten()):
grouped.get_group(key).plot(ax=ax)
ax.legend()
plt.show()
The latest update with hooks is to use useRouteMatch
.
export default function NestingExample() {
return (
<Router>
<Switch>
<Route path="/topics">
<Topics />
</Route>
</Switch>
</Router>
);
}
function Topics() {
// The `path` lets us build <Route> paths
// while the `url` lets us build relative links.
let { path, url } = useRouteMatch();
return (
<div>
<h2>Topics</h2>
<h5>
<Link to={`${url}/otherpath`}>/topics/otherpath/</Link>
</h5>
<ul>
<li>
<Link to={`${url}/topic1`}>/topics/topic1/</Link>
</li>
<li>
<Link to={`${url}/topic2`}>/topics/topic2</Link>
</li>
</ul>
// You can then use nested routing inside the child itself
<Switch>
<Route exact path={path}>
<h3>Please select a topic.</h3>
</Route>
<Route path={`${path}/:topicId`}>
<Topic />
</Route>
<Route path={`${path}/otherpath`>
<OtherPath/>
</Route>
</Switch>
</div>
);
}
You can create enums to deal with errors :)
enum RikhError: Error {
case unknownError
case connectionError
case invalidCredentials
case invalidRequest
case notFound
case invalidResponse
case serverError
case serverUnavailable
case timeOut
case unsuppotedURL
}
and then create a method inside enum to receive the http response code and return the corresponding error in return :)
static func checkErrorCode(_ errorCode: Int) -> RikhError {
switch errorCode {
case 400:
return .invalidRequest
case 401:
return .invalidCredentials
case 404:
return .notFound
//bla bla bla
default:
return .unknownError
}
}
Finally update your failure block to accept single parameter of type RikhError :)
I have a detailed tutorial on how to restructure traditional Objective - C based Object Oriented network model to modern Protocol Oriented model using Swift3 here https://learnwithmehere.blogspot.in Have a look :)

Adding more to Andreas' answer. I had the same problem with ES6 code, but I did not want to mutate the imports. That looked hacky. So I did this:
import myModule from '../myModule';
import dependency from '../dependency';
jest.mock('../dependency');
describe('myModule', () => {
it('calls the dependency with double the input', () => {
myModule(2);
});
});
And added file dependency.js in the " __ mocks __" folder parallel to file dependency.js. This worked for me. Also, this gave me the option to return suitable data from the mock implementation. Make sure you give the correct path to the module you want to mock.
For those using CloudFormation template. You can set AWS_DEFAULT_REGION
environment variable using UserData and AWS::Region
. For example,
MyInstance1:
Type: AWS::EC2::Instance
Properties:
ImageId: ami-04b9e92b5572fa0d1 #ubuntu
InstanceType: t2.micro
UserData:
Fn::Base64: !Sub |
#!/bin/bash -x
echo "export AWS_DEFAULT_REGION=${AWS::Region}" >> /etc/profile
Observe if the view has the model required:
View
@model IEnumerable<WFAccess.Models.ViewModels.SiteViewModel>
<div class="row">
<table class="table table-striped table-hover table-width-custom">
<thead>
<tr>
....
Controller
[HttpGet]
public ActionResult ListItems()
{
SiteStore site = new SiteStore();
site.GetSites();
IEnumerable<SiteViewModel> sites =
site.SitesList.Select(s => new SiteViewModel
{
Id = s.Id,
Type = s.Type
});
return PartialView("_ListItems", sites);
}
In my case I Use a partial view but runs in normal views
You can use list open file command and then kill the process like below.
sudo lsof -t -i tcp:8181 | xargs kill -9
or
sudo lsof -i tcp:8181
kill -9 PID
That would be:
b.rstrip('\n')
If you want to strip space from each and every line, you might consider instead:
a.read().splitlines()
This will give you a list of lines, without the line end characters.
In most of cases it is data log problem. Follow the steps.
i) Go to data folder of mysql. For xampp go to C:\xampp\mysql\data.
ii) Look for log file name like ib_logfile0 and ib_logfile1.
iii) Create backup and delete those files.
iv) Restart apache and mysql.
This worked for me:
select * from mytable
where array_to_string(pub_types, ',') like '%Journal%'
Depending on your normalization needs, it might be better to implement a separate table with a FK reference as you may get better performance and manageability.

To remove this comma, I wrote some simple code.
import json
with open('a.json','r') as f:
s = f.read()
s = s.replace('\t','')
s = s.replace('\n','')
s = s.replace(',}','}')
s = s.replace(',]',']')
data = json.loads(s)
And this worked for me.
Sorry that was a typo. You can either add node_modules to the end of your user's global path variable, or maybe check the permissions associated with that folder (node _modules). The error doesn't seem like the last case, but I've encountered problems similar to yours. I find the first solution enough for most cases. Just go to environment variables and add the path to node_modules to the last part of your user's path variable. Note I'm saying user and not system.
Just add a semicolon to the end of the variable declaration and add the static path to your node_module folder. ( Ex c:\path\to\node_module)
Alternatively you could:
In your CMD
PATH=%PATH%;C:\\path\to\node_module
EDIT
The last solution will work as long as you don't close your CMD. So, use the first solution for a permanent change.
I was able to stop via this on Windows for Angular 8:
Step 1: Find 4200 process
netstat -ano | findstr :4200
Step 2: Kill that process:
taskkill /PID <PID> /F
I needed to pass both: a file and an integer. I did it this way:
needed to pass a file to upload: did it as per Sumit's answer.
Request type : POST
Body -> form-data
under the heading KEY, entered the name of the variable ('file' in my backend code).
in the backend:
file = request.files['file']
Next to 'file', there's a drop-down box which allows you to choose between 'File' or 'Text'. Chose 'File' and under the heading VALUE, 'Select files' appeared. Clicked on this which opened a window to select the file.
2. needed to pass an integer:
went to:
Params
entered variable name (e.g.: id) under KEY and its value (e.g.: 1) under VALUE
in the backend:
id = request.args.get('id')
Worked!
If you use the Angular CLI to create your components, let's say CarComponent
, it attaches app
to the selector name (i.e app-car
) and this throws the above error when you reference the component in the parent view. Therefore you either have to change the selector name in the parent view to let's say <app-car></app-car>
or change the selector in the CarComponent
to selector: 'car'
I've implemented auto_add_key
in my pysftp github fork.
auto_add_key
will add the key to known_hosts
if auto_add_key=True
Once a key is present for a host in known_hosts
this key will be checked.
Please reffer Martin Prikryl -> answer about security concerns.
Though for an absolute security, you should not retrieve the host key remotely, as you cannot be sure, if you are not being attacked already.
import pysftp as sftp
def push_file_to_server():
s = sftp.Connection(host='138.99.99.129', username='root', password='pass', auto_add_key=True)
local_path = "testme.txt"
remote_path = "/home/testme.txt"
s.put(local_path, remote_path)
s.close()
push_file_to_server()
Note: Why using context manager
import pysftp
with pysftp.Connection(host, username="whatever", password="whatever", auto_add_key=True) as sftp:
#do your stuff here
#connection closed
You should change/add in your PostController: (and change PostsController to PostController)
public function create()
{
$categories = Category::all();
return view('create',compact('categories'));
}
public function store(Request $request)
{
$post = new Posts;
$post->title = $request->get('title'); // CHANGE THIS
$post->body = $request->get('body'); // CHANGE THIS
$post->save(); // ADD THIS
$post->categories()->attach($request->get('categories_id')); // CHANGE THIS
return redirect()->route('posts.index'); // PS ON THIS ONE
}
PS: using route() means you have named your route as such
Route::get('example', 'ExampleController@getExample')->name('getExample');
UPDATE
The comments above are also right, change your 'Posts' Model to 'Post'
string(byteslice) will convert byte slice to string, just know that it's not only simply type conversion, but also memory copy.
When I tried cloning from the remote, got the same issue repeatedly:
remote: Counting objects: 182, done.
remote: Compressing objects: 100% (149/149), done.
error: RPC failed; curl 18 transfer closed with outstanding read data remaining
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
Finally this worked for me:
git clone https://[email protected]/repositoryName.git --depth 1
Had a similar problem. I updated my Genymotion and my android SDK's/libraries/dependencies and all seemed to work. To update my SDK's I used android sdk manager {ANDROID_SDK_FOLDER}/tools/android sdk
Open C:\Users\Username.gradle\wrapper\dists\
Open latest gradle folder, e.g. gradle-4.1-rc-1-all
You will find a random folder named 936kh1brdchce6fvd2c1o8t8x
Download zip file of similar name
eg: https://downloads.gradle.org/distributions/gradle-4.1-rc-1-all.zip
Save it in this folder
Restart Android studio
It will automatically extract the zip folder and Error will clear
It took me a while to figure out the solution to this problem - it's in the original question. You need to have a script
that calls tsc
in your package.json
file so that you can run:
npm run tsc
Include --
before you pass in options (or just include them in the script):
npm run tsc -- -v
Here's an example package.json
:
{
"name": "foo",
"scripts": {
"tsc": "tsc"
},
"dependencies": {
"typescript": "^1.8.10"
}
}
This is a few months late but I thought I'd provide my solution based on this here tutorial. The gist of it is that it's a lot easier to manage once you change the way you approach forms.
First, use ReactiveFormsModule
instead of or in addition to the normal FormsModule
. With reactive forms you create your forms in your components/services and then plug them into your page instead of your page generating the form itself. It's a bit more code but it's a lot more testable, a lot more flexible, and as far as I can tell the best way to make a lot of non-trivial forms.
The end result will look a little like this, conceptually:
You have one base FormGroup
with whatever FormControl
instances you need for the entirety of the form. For example, as in the tutorial I linked to, lets say you want a form where a user can input their name once and then any number of addresses. All of the one-time field inputs would be in this base form group.
Inside that FormGroup
instance there will be one or more FormArray
instances. A FormArray
is basically a way to group multiple controls together and iterate over them. You can also put multiple FormGroup
instances in your array and use those as essentially "mini-forms" nested within your larger form.
By nesting multiple FormGroup
and/or FormControl
instances within a dynamic FormArray
, you can control validity and manage the form as one, big, reactive piece made up of several dynamic parts. For example, if you want to check if every single input is valid before allowing the user to submit, the validity of one sub-form will "bubble up" to the top-level form and the entire form becomes invalid, making it easy to manage dynamic inputs.
As a FormArray
is, essentially, a wrapper around an array interface but for form pieces, you can push, pop, insert, and remove controls at any time without recreating the form or doing complex interactions.
In case the tutorial I linked to goes down, here some sample code you can implement yourself (my examples use TypeScript) that illustrate the basic ideas:
Base Component code:
import { Component, Input, OnInit } from '@angular/core';
import { FormArray, FormBuilder, FormGroup, Validators } from '@angular/forms';
@Component({
selector: 'my-form-component',
templateUrl: './my-form.component.html'
})
export class MyFormComponent implements OnInit {
@Input() inputArray: ArrayType[];
myForm: FormGroup;
constructor(private fb: FormBuilder) {}
ngOnInit(): void {
let newForm = this.fb.group({
appearsOnce: ['InitialValue', [Validators.required, Validators.maxLength(25)]],
formArray: this.fb.array([])
});
const arrayControl = <FormArray>newForm.controls['formArray'];
this.inputArray.forEach(item => {
let newGroup = this.fb.group({
itemPropertyOne: ['InitialValue', [Validators.required]],
itemPropertyTwo: ['InitialValue', [Validators.minLength(5), Validators.maxLength(20)]]
});
arrayControl.push(newGroup);
});
this.myForm = newForm;
}
addInput(): void {
const arrayControl = <FormArray>this.myForm.controls['formArray'];
let newGroup = this.fb.group({
/* Fill this in identically to the one in ngOnInit */
});
arrayControl.push(newGroup);
}
delInput(index: number): void {
const arrayControl = <FormArray>this.myForm.controls['formArray'];
arrayControl.removeAt(index);
}
onSubmit(): void {
console.log(this.myForm.value);
// Your form value is outputted as a JavaScript object.
// Parse it as JSON or take the values necessary to use as you like
}
}
Sub-Component Code: (one for each new input field, to keep things clean)
import { Component, Input } from '@angular/core';
import { FormGroup } from '@angular/forms';
@Component({
selector: 'my-form-sub-component',
templateUrl: './my-form-sub-component.html'
})
export class MyFormSubComponent {
@Input() myForm: FormGroup; // This component is passed a FormGroup from the base component template
}
Base Component HTML
<form [formGroup]="myForm" (ngSubmit)="onSubmit()" novalidate>
<label>Appears Once:</label>
<input type="text" formControlName="appearsOnce" />
<div formArrayName="formArray">
<div *ngFor="let control of myForm.controls['formArray'].controls; let i = index">
<button type="button" (click)="delInput(i)">Delete</button>
<my-form-sub-component [myForm]="myForm.controls.formArray.controls[i]"></my-form-sub-component>
</div>
</div>
<button type="button" (click)="addInput()">Add</button>
<button type="submit" [disabled]="!myForm.valid">Save</button>
</form>
Sub-Component HTML
<div [formGroup]="form">
<label>Property One: </label>
<input type="text" formControlName="propertyOne"/>
<label >Property Two: </label>
<input type="number" formControlName="propertyTwo"/>
</div>
In the above code I basically have a component that represents the base of the form and then each sub-component manages its own FormGroup
instance within the FormArray
situated inside the base FormGroup
. The base template passes along the sub-group to the sub-component and then you can handle validation for the entire form dynamically.
Also, this makes it trivial to re-order component by strategically inserting and removing them from the form. It works with (seemingly) any number of inputs as they don't conflict with names (a big downside of template-driven forms as far as I'm aware) and you still retain pretty much automatic validation. The only "downside" of this approach is, besides writing a little more code, you do have to relearn how forms work. However, this will open up possibilities for much larger and more dynamic forms as you go on.
If you have any questions or want to point out some errors, go ahead. I just typed up the above code based on something I did myself this past week with the names changed and other misc. properties left out, but it should be straightforward. The only major difference between the above code and my own is that I moved all of the form-building to a separate service that's called from the component so it's a bit less messy.
Yet another method to solve: updating registry. In my case I could not alter GPO, and -UseBasicParsing breaks parts of the access to the website. Also I had a service user without log in permissions, so I could not log in as the user and run the GUI.

One another way is to use the same thing what firebase uses.
For example when user logs in, firebase stores below details in local storage. When user comes back to the page, firebase uses the same method to identify if user should be logged in automatically.
ATTN: As this is neither listed or recommended by firebase. You can call this method un-official way of doing this. Which means later if firebase changes their inner working, this method may not work. Or in short. Use at your own risk! :)
You will have a server key something like this AIzaSyDiTEVq4Li1pj7IyraRlyRU9adc-49-KVY available in the Settings section of firebase console console.firebase.google.com/project/project-XXXXXXXXXXXXX/settings/cloudmessaging.
Specify the correct key with your code and try again.
Implement runtime permission for running your app on Android 6.0 Marshmallow (API 23) or later.
or you can manually enable the storage permission-
goto settings>apps> "your_app_name" >click on it >then click permissions> then enable the storage. Thats it.
But i suggest go the for first one which is, Implement runtime permissions in your code.
Recently Selenium has launched Selenium 3 and if you are trying to use Firefox latest version then you have to use GeckoDriver:
System.setProperty("webdriver.gecko.driver","G:\\Selenium\\Firefox driver\\geckodriver.exe");
WebDriver driver = new FirefoxDriver();
One of the fundamental principles behind a promise is that it's handled asynchronously. This means that you cannot create a promise and then immediately use its result synchronously in your code (e.g. it's not possible to return the result of a promise from within the function that initiated the promise).
What you likely want to do instead is to return the entire promise itself. Then whatever function needs its result can call .then()
on the promise, and the result will be there when the promise has been resolved.
Here is a resource from HTML5Rocks that goes over the lifecycle of a promise, and how its output is resolved asynchronously:

In my case nginx container was keep on restarting , I checked logs of nginx container and came to know .crt and .key file of a unrequired domain are having errors , so I removed respective .conf file , .crt and .key and then restarted nginx . That's it nginx is working fine without restarting .
I have posted this answer as this question was viewed most and this server side code was written in VS 2015 in C# for sending push notification either single device based on device id or subscribed topic to Xamarin Android app

You could also get the error if your Billing is not set up correctly.
Google hands out credit worth $300 or 12 months of free usage whichever runs out faster. After that you would need to enable billing.
I was getting this error even when all the relevant dependencies were in place because I hadn't created the schema in MySQL.
I thought it would be created automatically but it wasn't. Although the table itself will be created, you have to create the schema.
It may come when the API(you are consuming) is not sending the corresponding JSON. You may experience the response as 404 page or something like HTML/XML response.
You are using the wrong build.gradle
file.
In your top-level file you can't define an android
block.
Just move this part inside the module/build.gradle
file.
android {
compileSdkVersion 17
buildToolsVersion '23.0.0'
}
dependencies {
compile files('app/libs/junit-4.12-JavaDoc.jar')

There were several projects available that reverse engineered the WhatsApp webservice interfaces. However, to my knowledge all of them are now discontinued/defunct due to legal action against them from WhatsApp.
For mobile phone applications there is a limited URL-Scheme-API available on IPhone and Android (Android-intent possible as well).
You need to put your code into ngOnInit
and use the this
keyword:
ngOnInit() {
this.booksByStoreID = this.books.filter(
book => book.store_id === this.store.id);
}
You need ngOnInit
because the input store
wouldn't be set into the constructor:
ngOnInit is called right after the directive's data-bound properties have been checked for the first time, and before any of its children have been checked. It is invoked only once when the directive is instantiated.
(https://angular.io/docs/ts/latest/api/core/index/OnInit-interface.html)
In your code, the books filtering is directly defined into the class content...
Make sure "App Domain" and Facebook Login => Valid OAuth redirect URIs. There you must check www or without www. Its better if you use with www or without for all URLs in php,html,css files and Fb app settings.
Other thing is if you're using "/" end of the URLs you must add that URL to app settings of Valid OAuth redirect URIs. Example:- https://www.example.com/index.php/ if this url if youre using in the redirect url you must set that to app settings.
Hope this would be help.
In most cases, it is enough just to hide the element, for example in this way:
export default class ErrorBoxComponent extends React.Component {
constructor(props) {
super(props);
this.state = {
isHidden: false
}
}
dismiss() {
this.setState({
isHidden: true
})
}
render() {
if (!this.props.error) {
return null;
}
return (
<div data-alert className={ "alert-box error-box " + (this.state.isHidden ? 'DISPLAY-NONE-CLASS' : '') }>
{ this.props.error }
<a href="#" className="close" onClick={ this.dismiss.bind(this) }>×</a>
</div>
);
}
}
Or you may render/rerender/not render via parent component like this
export default class ParentComponent extends React.Component {
constructor(props) {
super(props);
this.state = {
isErrorShown: true
}
}
dismiss() {
this.setState({
isErrorShown: false
})
}
showError() {
if (this.state.isErrorShown) {
return <ErrorBox
error={ this.state.error }
dismiss={ this.dismiss.bind(this) }
/>
}
return null;
}
render() {
return (
<div>
{ this.showError() }
</div>
);
}
}
export default class ErrorBoxComponent extends React.Component {
dismiss() {
this.props.dismiss();
}
render() {
if (!this.props.error) {
return null;
}
return (
<div data-alert className="alert-box error-box">
{ this.props.error }
<a href="#" className="close" onClick={ this.dismiss.bind(this) }>×</a>
</div>
);
}
}
Finally, there is a way to remove html node, but i really dont know is it a good idea. Maybe someone who knows React from internal will say something about this.
export default class ErrorBoxComponent extends React.Component {
dismiss() {
this.el.remove();
}
render() {
if (!this.props.error) {
return null;
}
return (
<div data-alert className="alert-box error-box" ref={ (el) => { this.el = el} }>
{ this.props.error }
<a href="#" className="close" onClick={ this.dismiss.bind(this) }>×</a>
</div>
);
}
}
If you use JDK 8+, there is a one line lambda solution:
@EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Override
protected void configure(HttpSecurity http) throws Exception {
http.cors().configurationSource(request -> new CorsConfiguration().applyPermitDefaultValues());
}
If you use McAfee Antivirus and Windows 10 this might help you:
Uninstalling and reinstalling Android Emulator as snehatilak suggested initially helped in my case, though the next day the emulator was dead yet again.
I found that McAfee antivirus had quarantined the file AVD.conf that had been in C:\Users[username].android\avd[avdImage]\
After restoring AVD.conf and excluding it from scans it seems to be ok again.
This all started 02.02.2021 after what I guess was an McAfee update.
Here are the steps:
First go to 'Quarantined items' under Settings and restore the AVD.conf file
Then go to 'Real-Time Scanning' under Settings and exclude AVD.conf in each emulator you have created. (Located under C:\Users[username].android\avd[avdImage])
In order to understand the use of curly braces in import
statements, first, you have to understand the concept of destructuring introduced in ES6
Object destructuring
var bodyBuilder = {
firstname: 'Kai',
lastname: 'Greene',
nickname: 'The Predator'
};
var {firstname, lastname} = bodyBuilder;
console.log(firstname, lastname); // Kai Greene
firstname = 'Morgan';
lastname = 'Aste';
console.log(firstname, lastname); // Morgan Aste
Array destructuring
var [firstGame] = ['Gran Turismo', 'Burnout', 'GTA'];
console.log(firstGame); // Gran Turismo
Using list matching
var [,secondGame] = ['Gran Turismo', 'Burnout', 'GTA'];
console.log(secondGame); // Burnout
Using the spread operator
var [firstGame, ...rest] = ['Gran Turismo', 'Burnout', 'GTA'];
console.log(firstGame);// Gran Turismo
console.log(rest);// ['Burnout', 'GTA'];
Now that we've got that out of our way, in ES6 you can export multiple modules. You can then make use of object destructuring like below.
Let's assume you have a module called module.js
export const printFirstname(firstname) => console.log(firstname);
export const printLastname(lastname) => console.log(lastname);
You would like to import the exported functions into index.js
;
import {printFirstname, printLastname} from './module.js'
printFirstname('Taylor');
printLastname('Swift');
You can also use different variable names like so
import {printFirstname as pFname, printLastname as pLname} from './module.js'
pFname('Taylor');
pLanme('Swift');
curl 7.19.7 (x86_64-redhat-linux-gnu) libcurl/7.19.7 NSS/3.19.1 Basic ECC zlib/1.2.3 libidn/1.18 libssh2/1.4.2
You are using a very old version of curl. My guess is that you run into the bug described 6 years ago. Fix is to update your curl.
<div class="modal fade" id="myModal" aria-hidden="true">
...
...
</div>
Note: Remove fade class from the div and enjoy it should be worked
Let's assume you want to overwrite the same file:
import json
with open('data.json', 'r') as data_file:
data = json.load(data_file)
for element in data:
element.pop('hours', None)
with open('data.json', 'w') as data_file:
data = json.dump(data, data_file)
dict.pop(<key>, not_found=None)
is probably what you where looking for, if I understood your requirements. Because it will remove the hours
key if present and will not fail if not present.
However I am not sure I understand why it makes a difference to you whether the hours key contains some days or not, because you just want to get rid of the whole key / value pair, right?
Now, if you really want to use del
instead of pop
, here is how you could make your code work:
import json
with open('data.json') as data_file:
data = json.load(data_file)
for element in data:
if 'hours' in element:
del element['hours']
with open('data.json', 'w') as data_file:
data = json.dump(data, data_file)
EDIT So, as you can see, I added the code to write the data back to the file. If you want to write it to another file, just change the filename in the second open statement.
I had to change the indentation, as you might have noticed, so that the file has been closed during the data cleanup phase and can be overwritten at the end.
with
is what is called a context manager, whatever it provides (here the data_file file descriptor) is available ONLY within that context. It means that as soon as the indentation of the with
block ends, the file gets closed and the context ends, along with the file descriptor which becomes invalid / obsolete.
Without doing this, you wouldn't be able to open the file in write mode and get a new file descriptor to write into.
I hope it's clear enough...
SECOND EDIT
This time, it seems clear that you need to do this:
with open('dest_file.json', 'w') as dest_file:
with open('source_file.json', 'r') as source_file:
for line in source_file:
element = json.loads(line.strip())
if 'hours' in element:
del element['hours']
dest_file.write(json.dumps(element))
3 answers, which you can combine:
Set implicit wait immediately after creating the web driver instance:
_ = driver.Manage().Timeouts().ImplicitWait;
This will try to wait until the page is fully loaded on every page navigation or page reload.
After page navigation, call JavaScript return document.readyState
until "complete"
is returned. The web driver instance can serve as JavaScript executor. Sample code:
C#
new WebDriverWait(driver, MyDefaultTimeout).Until(
d => ((IJavaScriptExecutor) d).ExecuteScript("return document.readyState").Equals("complete"));
Java
new WebDriverWait(firefoxDriver, pageLoadTimeout).until(
webDriver -> ((JavascriptExecutor) webDriver).executeScript("return document.readyState").equals("complete"));
Check if the URL matches the pattern you expect.
You turn off pack_propagate
by setting pack_propagate(0)
Turning off pack_propagate
here basically says don't let the widgets inside the frame control it's size. So you've set it's width and height to be 500. Turning off propagate stills allows it to be this size without the widgets changing the size of the frame to fill their respective width / heights which is what would happen normally
To turn off resizing the root window, you can set root.resizable(0, 0)
, where resizing is allowed in the x
and y
directions respectively.
To set a maxsize to window, as noted in the other answer you can set the maxsize
attribute or minsize
although you could just set the geometry of the root window and then turn off resizing. A bit more flexible imo.
Whenever you set grid
or pack
on a widget it will return None
. So, if you want to be able to keep a reference to the widget object you shouldn't be setting a variabe to a widget where you're calling grid
or pack
on it. You should instead set the variable to be the widget Widget(master, ....)
and then call pack
or grid
on the widget instead.

I ran into this issue as well and found this post. Ultimately none of these answers solved my problem, instead I had to put in a rewrite rule to strip out the location /rt
as the backend my developers made was not expecting any additional paths:
+-(william@wkstn18)--(Thu, 05 Nov 20)-+
+-(~)--(16:13)->wscat -c ws://WebsocketServerHostname/rt
error: Unexpected server response: 502
Testing with wscat repeatedly gave a 502 response. Nginx error logs provided the same upstream error as above, but notice the upstream string shows the GET Request is attempting to access localhost:12775/rt and not localhost:12775:
2020/11/05 22:13:32 [error] 10175#10175: *7 upstream prematurely closed
connection while reading response header from upstream, client: WANIP,
server: WebsocketServerHostname, request: "GET /rt/socket.io/?transport=websocket
HTTP/1.1", upstream: "http://127.0.0.1:12775/rt/socket.io/?transport=websocket",
host: "WebsocketServerHostname"
Since the devs had not coded their websocket (listening on 12775) to expect /rt/socket.io but instead just /socket.io/ (NOTE: /socket.io/ appears to just be a way to specify websocket transport discussed here). Because of this, rather than ask them to rewrite their socket code I just put in a rewrite rule to translate WebsocketServerHostname/rt to WebsocketServerHostname:12775 as below:
upstream websocket-rt {
ip_hash;
server 127.0.0.1:12775;
}
server {
listen 80;
server_name WebsocketServerHostname;
location /rt {
proxy_http_version 1.1;
#rewrite /rt/ out of all requests and proxy_pass to 12775
rewrite /rt/(.*) /$1 break;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $host;
proxy_pass http://websocket-rt;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection $connection_upgrade;
}
}
Now that TypeScript 2.2 supports Mixins through Class expressions we have a much better way to express Mixins on Components. Mind you that you can also use Component inheritance since angular 2.3 (discussion) or a custom decorator as discussed in other answers here. However, I think Mixins have some properties that make them preferable for reusing behavior across components:
I strongly suggest you read the TypeScript 2.2 announcement above to understand how Mixins work. The linked discussions in angular GitHub issues provide additional detail.
You'll need these types:
export type Constructor<T> = new (...args: any[]) => T;
export class MixinRoot {
}
And then you can declare a Mixin like this Destroyable
mixin that helps components keep track of subscriptions that need to be disposed in ngOnDestroy
:
export function Destroyable<T extends Constructor<{}>>(Base: T) {
return class Mixin extends Base implements OnDestroy {
private readonly subscriptions: Subscription[] = [];
protected registerSubscription(sub: Subscription) {
this.subscriptions.push(sub);
}
public ngOnDestroy() {
this.subscriptions.forEach(x => x.unsubscribe());
this.subscriptions.length = 0; // release memory
}
};
}
To mixin Destroyable
into a Component
, you declare your component like this:
export class DashboardComponent extends Destroyable(MixinRoot)
implements OnInit, OnDestroy { ... }
Note that MixinRoot
is only necessary when you want to extend
a Mixin composition. You can easily extend multiple mixins e.g. A extends B(C(D))
. This is the obvious linearization of mixins I was talking about above, e.g. you're effectively composing an inheritnace hierarchy A -> B -> C -> D
.
In other cases, e.g. when you want to compose Mixins on an existing class, you can apply the Mixin like so:
const MyClassWithMixin = MyMixin(MyClass);
However, I found the first way works best for Components
and Directives
, as these also need to be decorated with @Component
or @Directive
anyway.
What SSL private key should be sent along with the client certificate?
None of them :)
One of the appealing things about client certificates is it does not do dumb things, like transmit a secret (like a password), in the plain text to a server (HTTP basic_auth
). The password is still used to unlock the key for the client certificate, its just not used directly to during exchange or tp authenticate the client.
Instead, the client chooses a temporary, random key for that session. The client then signs the temporary, random key with his cert and sends it to the server (some hand waiving). If a bad guy intercepts anything, its random so it can't be used in the future. It can't even be used for a second run of the protocol with the server because the server will select a new, random value, too.
Fails with: error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure
Use TLS 1.0 and above; and use Server Name Indication.
You have not provided any code, so its not clear to me how to tell you what to do. Instead, here's the OpenSSL command line to test it:
openssl s_client -connect www.example.com:443 -tls1 -servername www.example.com \
-cert mycert.pem -key mykey.pem -CAfile <certificate-authority-for-service>.pem
You can also use -CAfile
to avoid the “verify error:num=20”. See, for example, “verify error:num=20” when connecting to gateway.sandbox.push.apple.com.
You forget the @ID above the userId
I was having the same problem while making a POST request from Postman and later I could solve the problem by setting a custom Content-Type with a boundary value set along with it like this.
I thought people can run into similar problem and hence, I'm sharing my solution.
call private method using square brackets
Ts file
class Calculate{
private total;
private add(a: number) {
return a + total;
}
}
spect.ts file
it('should return 5 if input 3 and 2', () => {
component['total'] = 2;
let result = component['add'](3);
expect(result).toEqual(5);
});
I found this clickOut
directive:
https://github.com/chliebel/angular2-click-outside. I check it and it works well (i only copy clickOutside.directive.ts
to my project). U can use it in this way:
<div (clickOutside)="close($event)"></div>
Where close
is your function which will be call when user click outside div. It is very elegant way to handle problem described in question.
If you use above directive to close popUp window, remember first to add event.stopPropagation()
to button click event handler which open popUp.
Below i copy oryginal directive code from file clickOutside.directive.ts
(in case if link will stop working in future) - the author is Christian Liebel :
import {Directive, ElementRef, Output, EventEmitter, HostListener} from '@angular/core';_x000D_
_x000D_
@Directive({_x000D_
selector: '[clickOutside]'_x000D_
})_x000D_
export class ClickOutsideDirective {_x000D_
constructor(private _elementRef: ElementRef) {_x000D_
}_x000D_
_x000D_
@Output()_x000D_
public clickOutside = new EventEmitter<MouseEvent>();_x000D_
_x000D_

}_x000D_
_x000D_
const clickedInside = this._elementRef.nativeElement.contains(targetElement);_x000D_

In my case (using ASP.NET Core 3.1 and Visual Studio Professional 2019), I've seen this twice and in both cases fixing it was as simple as rebooting my PC.
I strongly suspect, but can't prove, that this could also be accomplished by restarting only a specific process (like in @Codenova's answer).
Pandas allows you to plot tables using matplotlib (details here). Usually this plots the table directly onto a plot (with axes and everything) which is not what you want. However, these can be removed first:
import matplotlib.pyplot as plt
import pandas as pd
from pandas.table.plotting import table # EDIT: see deprecation warnings below
ax = plt.subplot(111, frame_on=False) # no visible frame
ax.xaxis.set_visible(False) # hide the x axis
ax.yaxis.set_visible(False) # hide the y axis
table(ax, df) # where df is your data frame
plt.savefig('mytable.png')
The output might not be the prettiest but you can find additional arguments for the table() function here. Also thanks to this post for info on how to remove axes in matplotlib.
Here is a (admittedly quite hacky) way of simulating multi-indexes when plotting using the method above. If you have a multi-index data frame called df that looks like:
first second
bar one 1.991802
two 0.403415
baz one -1.024986
two -0.522366
foo one 0.350297
two -0.444106
qux one -0.472536
two 0.999393
dtype: float64
First reset the indexes so they become normal columns
df = df.reset_index()
df
first second 0
0 bar one 1.991802
1 bar two 0.403415
2 baz one -1.024986
3 baz two -0.522366
4 foo one 0.350297
5 foo two -0.444106
6 qux one -0.472536
7 qux two 0.999393
Remove all duplicates from the higher order multi-index columns by setting them to an empty string (in my example I only have duplicate indexes in "first"):
df.ix[df.duplicated('first') , 'first'] = '' # see deprecation warnings below
df
first second 0
0 bar one 1.991802
1 two 0.403415
2 baz one -1.024986
3 two -0.522366
4 foo one 0.350297
5 two -0.444106
6 qux one -0.472536
7 two 0.999393
Change the column names over your "indexes" to the empty string
new_cols = df.columns.values
new_cols[:2] = '','' # since my index columns are the two left-most on the table
df.columns = new_cols
Now call the table function but set all the row labels in the table to the empty string (this makes sure the actual indexes of your plot are not displayed):
table(ax, df, rowLabels=['']*df.shape[0], loc='center')
et voila:
Your not-so-pretty but totally functional multi-indexed table.
As pointed out in the comments, the import statement for table
:
from pandas.tools.plotting import table
is now deprecated in newer versions of pandas in favour of:
from pandas.plotting import table
The ix
indexer has now been fully deprecated so we should use the loc
indexer instead. Replace:
df.ix[df.duplicated('first') , 'first'] = ''
with
df.loc[df.duplicated('first') , 'first'] = ''
You can customize the way that both the .fromNow
and the .calendar
methods display dates using moment.updateLocale
. The following code will change the way that .calendar
displays as per the question:
moment.updateLocale('en', {
calendar : {
lastDay : '[Yesterday]',
sameDay : '[Today]',
nextDay : '[Tomorrow]',
lastWeek : '[Last] dddd',
nextWeek : '[Next] dddd',
sameElse : 'L'
}
});
Based on the question, it seems like the .calendar
method would be more appropriate -- .fromNow
wants to have a past/present prefix/suffix, but if you'd like to find out more you can read the documentation at http://momentjs.com/docs/#/customization/relative-time/.
To use this in only one place instead of overwriting the locales, pass a string of your choice as the first argument when you define the moment.updateLocale
and then invoke the calendar method using that locale (eg. moment.updateLocale('yesterday-today').calendar( /* moment() or whatever */ )
)
EDIT: Moment ^2.12.0 now has the updateLocale
method. updateLocale
and locale
appear to be functionally the same, and locale
isn't yet deprecated, but updated the answer to use the newer method.
An alternative to the answer SnareChops gave.
You can use .bind(this) in your template to have the same effect. It may not be as clean but it saves a couple of lines. I'm currently on angular 2.4.0
@Component({
...
template: '<child [myCallback]="theCallback.bind(this)"></child>',
directives: [ChildComponent]
})
export class ParentComponent {
public theCallback(){
...
}
}
@Component({...})
export class ChildComponent{
//This will be bound to the ParentComponent.theCallback
@Input()
public myCallback: Function;
...
}
If you stored the complete model, not only the weights, in the HDF5 file, then it is as simple as
from keras.models import load_model
model = load_model('model.h5')
Check out from dateutil.relativedelta import *
for adding a specific amount of time to a date, you can continue to use timedelta
for the simple stuff i.e.
use_date = use_date + datetime.timedelta(minutes=+10)
use_date = use_date + datetime.timedelta(hours=+1)
use_date = use_date + datetime.timedelta(days=+1)
use_date = use_date + datetime.timedelta(weeks=+1)
or you can start using relativedelta
use_date = use_date+relativedelta(months=+1)
use_date = use_date+relativedelta(years=+1)
for the last day of next month:
use_date = use_date+relativedelta(months=+1)
use_date = use_date+relativedelta(day=31)
Right now this will provide 29/02/2016
for the penultimate day of next month:
use_date = use_date+relativedelta(months=+1)
use_date = use_date+relativedelta(day=31)
use_date = use_date+relativedelta(days=-1)
last Friday of the next month:
use_date = use_date+relativedelta(months=+1, day=31, weekday=FR(-1))
2nd Tuesday of next month:
new_date = use_date+relativedelta(months=+1, day=1, weekday=TU(2))
As @mrroot5 points out dateutil's rrule
functions can be applied, giving you an extra bang for your buck, if you require date occurences.
for example:
Calculating the last day of the month for 9 months from the last day of last month.
Then, calculate the 2nd Tuesday for each of those months.
from dateutil.relativedelta import *
from dateutil.rrule import *
from datetime import datetime
use_date = datetime(2020,11,21)
#Calculate the last day of last month
use_date = use_date+relativedelta(months=-1)
use_date = use_date+relativedelta(day=31)
#Generate a list of the last day for 9 months from the calculated date
x = list(rrule(freq=MONTHLY, count=9, dtstart=use_date, bymonthday=(-1,)))
print("Last day")
for ld in x:
print(ld)
#Generate a list of the 2nd Tuesday in each of the next 9 months from the calculated date
print("\n2nd Tuesday")
x = list(rrule(freq=MONTHLY, count=9, dtstart=use_date, byweekday=TU(2)))
for tuesday in x:
print(tuesday)
Last day

This is by no means an exhaustive list of what is available. Documentation is available here: https://dateutil.readthedocs.org/en/latest/
Webpack and Browserify do pretty much the same job, which is processing your code to be used in a target environment (mainly browser, though you can target other environments like Node). Result of such processing is one or more bundles - assembled scripts suitable for targeted environment.
For example, let's say you wrote ES6 code divided into modules and want to be able to run it in a browser. If those modules are Node modules, the browser won't understand them since they exist only in the Node environment. ES6 modules also won't work in older browsers like IE11. Moreover, you might have used experimental language features (ES next proposals) that browsers don't implement yet so running such script would just throw errors. Tools like Webpack and Browserify solve these problems by translating such code to a form a browser is able to execute. On top of that, they make it possible to apply a huge variety of optimisations on those bundles.
However, Webpack and Browserify differ in many ways, Webpack offers many tools by default (e.g. code splitting), while Browserify can do this only after downloading plugins but using both leads to very similar results. It comes down to personal preference (Webpack is trendier). Btw, Webpack is not a task runner, it is just processor of your files (it processes them by so called loaders and plugins) and it can be run (among other ways) by a task runner.
Webpack Dev Server provides a similar solution to Browsersync - a development server where you can deploy your app rapidly as you are working on it, and verify your development progress immediately, with the dev server automatically refreshing the browser on code changes or even propagating changed code to browser without reloading with so called hot module replacement.
I've been using Gulp for its conciseness and easy task writing, but have later found out I need neither Gulp nor Grunt at all. Everything I have ever needed could have been done using NPM scripts to run 3rd-party tools through their API. Choosing between Gulp, Grunt or NPM scripts depends on taste and experience of your team.
While tasks in Gulp or Grunt are easy to read even for people not so familiar with JS, it is yet another tool to require and learn and I personally prefer to narrow my dependencies and make things simple. On the other hand, replacing these tasks with the combination of NPM scripts and (propably JS) scripts which run those 3rd party tools (eg. Node script configuring and running rimraf for cleaning purposes) might be more challenging. But in the majority of cases, those three are equal in terms of their results.
As for the examples, I suggest you have a look at this React starter project, which shows you a nice combination of NPM and JS scripts covering the whole build and deploy process. You can find those NPM scripts in package.json
in the root folder, in a property named scripts
. There you will mostly encounter commands like babel-node tools/run start
. Babel-node is a CLI tool (not meant for production use), which at first compiles ES6 file tools/run
(run.js file located in tools) - basically a runner utility. This runner takes a function as an argument and executes it, which in this case is start
- another utility (start.js
) responsible for bundling source files (both client and server) and starting the application and development server (the dev server will be probably either Webpack Dev Server or Browsersync).
Speaking more precisely, start.js
creates both client and server side bundles, starts an express server and after a successful launch initializes Browser-sync, which at the time of writing looked like this (please refer to react starter project for the newest code).
const bs = Browsersync.create();
bs.init({
...(DEBUG ? {} : { notify: false, ui: false }),
proxy: {
target: host,
middleware: [wpMiddleware, ...hotMiddlewares],
},
// no need to watch '*.js' here, webpack will take care of it for us,
// including full page reloads if HMR won't work
files: ['build/content/**/*.*'],
}, resolve)
The important part is proxy.target
, where they set server address they want to proxy, which could be http://localhost:3000, and Browsersync starts a server listening on http://localhost:3001, where the generated assets are served with automatic change detection and hot module replacement. As you can see, there is another configuration property files
with individual files or patterns Browser-sync watches for changes and reloads the browser if some occur, but as the comment says, Webpack takes care of watching js sources by itself with HMR, so they cooperate there.
Now I don't have any equivalent example of such Grunt or Gulp configuration, but with Gulp (and somewhat similarly with Grunt) you would write individual tasks in gulpfile.js like
gulp.task('bundle', function() {
// bundling source files with some gulp plugins like gulp-webpack maybe
});
gulp.task('start', function() {
// starting server and stuff
});
where you would be doing essentially pretty much the same things as in the starter-kit, this time with task runner, which solves some problems for you, but presents its own issues and some difficulties during learning the usage, and as I say, the more dependencies you have, the more can go wrong. And that is the reason I like to get rid of such tools.
You could use the 'isActive' prop like so:
const { router } = this.context;
if (router.isActive('/login')) {
router.push('/');
}
isActive will return a true or false.
Tested with react-router 2.7
On GKE, if the pod is dead, it's best to check for the events. It will show in more detail what the error is about.
In my case, I had :
Failed to pull image "gcr.io/project/imagename@sha256:c8e91af54fc17faa1c49e2a05def5cbabf8f0a67fc558eb6cbca138061a8400a":
rpc error: code = Unknown desc = error pulling image configuration: unknown blob
It turned out the image was damaged somehow. After repushing it and deploying with the new hash, it worked again.
You can do the following:
Example using PHP (you can do this in any language of your choice):
Server:
<?php $years = range(1900, strftime("%Y", time())); ?>
HTML
<select>
<option>Select Year</option>
<?php foreach($years as $year) : ?>
<option value="<?php echo $year; ?>"><?php echo $year; ?></option>
<?php endforeach; ?>
</select>
As an added benefit, this works has a browser compatibility of a 100% ;-)
I also experienced this error.
I add into header Content-Type
: application/json
. Following the change, my submissions succeed!
Looks like something is wrong with your data, it isn't in the format you are expecting. It could be a new line character or a blank space in the data that is tinkering with your code.
So basically, in jquery what we can do is to load href attribute using the load function. This way we can use the url in <a>
tag and load that in modal-body.
<a href='/site/login' class='ls-modal'>Login</a>
//JS script
$('.ls-modal').on('click', function(e){
e.preventDefault();
$('#myModal').modal('show').find('.modal-body').load($(this).attr('href'));
});
From here:
Root Cause: Maximum connection has been exceeded on your SQL Server Instance.
How to fix it...!
- F8 or Object Explorer
- Right click on Instance --> Click Properties...
- Select "Connections" on "Select a page" area at left
- Chenge the value to 0 (Zero) for "Maximum number of concurrent connections(0 = Unlimited)"
- Restart the SQL Server Instance once.
Apart from that also ensure that below are enabled:
Change the start field in package.json from:
"start": "tsc && concurrently \"npm run tsc:w\" \"npm run lite\" "
To:
"start": "concurrently \"npm run tsc:w\" \"npm run lite\" "
It really helped.

Mention the url
like:
jdbc:mysql://hostname:3306/hibernatedb?autoReconnect=true&useSSL=false
But in xml configuration when you mention &
sign, the IDE shows below error:
The reference to entity "useSSL" must end with the ';' delimiter.
And then you have to explicitly use the &
instead of &
to be determined as &
by xml
thereafter in xml
you have to give the url in xml configuration like this:
<property name="connection.url">jdbc:mysql://hostname:3306/hibernatedb?autoReconnect=true&useSSL=false</property>
If you know the aspect ratio for example, if your image is square you can set either the height

to fill the container and get the other to be set by the aspectRatio
property
Here is the style if you want the height
be set automatically:
{
width: '100%',
height: undefined,
aspectRatio: 1,
}
Note: height
must be undefined
I have created a Cards Layout - 3 cards in a row using Bootstrap 4 / CSS3 (of course its responsive). The following example uses basic Bootstrap 4 classes such as container
, row
, col-x
, list-group
and list-group-item
. Thought to share here if someone is interested in this sort of a layout.

The error means you cannot use the local variable mi
inside an inner class.
To use a variable inside an inner class you must declare it final
. As long as mi
is the counter of the loop and final
variables cannot be assigned, you must create a workaround to get mi
value in a final
variable that can be accessed inside inner class:
final Integer innerMi = new Integer(mi);
So your code will be like this:
for (int mi=0; mi<colors.length; mi++){
String pos = Character.toUpperCase(colors[mi].charAt(0)) + colors[mi].substring(1);
JMenuItem Jmi =new JMenuItem(pos);
Jmi.setIcon(new IconA(colors[mi]));
// workaround:
final Integer innerMi = new Integer(mi);
Jmi.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
JMenuItem item = (JMenuItem) e.getSource();
IconA icon = (IconA) item.getIcon();
// HERE YOU USE THE FINAL innerMi variable and no errors!!!
Color kolorIkony = getColour(colors[innerMi]);
textArea.setForeground(kolorIkony);
}
});
mnForeground.add(Jmi);
}
}

EDIT : Works with design library upto 23.0.1 but doesn't work on 23.1.0
In main layout xml you will have NavigationView
defined, in that use app:headerLayout
to set the header view.
<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/nav_drawer_header"
app:menu="@menu/navigation_drawer_menu" />
And the @layout/nav_drawer_header
will be the place holder of the image and texts.
nav_drawer_header.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="170dp"
android:orientation="vertical">
<RelativeLayout
android:id="@+id/headerRelativeLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scaleType="fitXY"
android:src="@drawable/background" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="@dimen/action_bar_size"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:background="#40000000"
android:gravity="center"
android:orientation="horizontal"
android:paddingBottom="5dp"
android:paddingLeft="16dp"
android:paddingRight="10dp"
android:paddingTop="5dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginLeft="35dp"
android:orientation="vertical"
android:weightSum="2">
<TextView
android:id="@+id/navHeaderTitle"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textColor="@android:color/white" />
<TextView
android:id="@+id/navHeaderSubTitle"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textColor="@android:color/white" />
</LinearLayout>
</LinearLayout>
</RelativeLayout>
</LinearLayout>
And in your main class, you can take handle of Imageview
and TextView
as like normal other views.
TextView navHeaderTitle = (TextView) findViewById(R.id.navHeaderTitle);
navHeaderTitle.setText("Application Name");
TextView navHeaderSubTitle = (TextView) findViewById(R.id.navHeaderSubTitle);
navHeaderSubTitle.setText("Application Caption");
Hope this helps.
It turns out that it was shrinking and growing correctly, providing the desired behaviour all along; except that in all current browsers flexbox wasn't accounting for the vertical scrollbar! Which is why the content appears to be getting cut off.
You can see here, which is the original code I was using before I added the fixed widths, that it looks like the column isn't growing to accomodate the text:
http://jsfiddle.net/2w157dyL/1/
However if you make the content in that column wider, you'll see that it always cuts it off by the same amount, which is the width of the scrollbar.
So the fix is very, very simple - add enough right padding to account for the scrollbar:
http://jsfiddle.net/2w157dyL/2/
main > section {_x000D_
overflow-y: auto;_x000D_
padding-right: 2em;_x000D_
}
_x000D_
It was when I was trying some things suggested by Michael_B (specifically adding a padding buffer) that I discovered this, thanks so much!
Edit: I see that he also posted a fiddle which does the same thing - again, thanks so much for all your help
I am using rails and ajax too and I had the same problem. just run this code
$('#modalName').modal('hide');
that worked for me but I am trying to also fix it without using jQuery.
You can use alexw's solution with the Artisan. Run following commands in the command line.
php artisan tinker
DB::connection()->getPdo();
If connection is OK, you should see
CONNECTION_STATUS: "Connection OK; waiting to send.",
near the end of the response.
This is Function which will convert most of the video formats to number of frames there are in the video. It works on Python3
with OpenCV 3+
import cv2
import time
import os
def video_to_frames(input_loc, output_loc):
"""Function to extract frames from input video file
and save them as separate frames in an output directory.

"""
try:
os.mkdir(output_loc)
except OSError:
pass
# Log the time
time_start = time.time()
# Start capturing the feed
cap = cv2.VideoCapture(input_loc)
# Find the number of frames
video_length = int(cap.get(cv2.CAP_PROP_FRAME_COUNT)) - 1
print ("Number of frames: ", video_length)
count = 0
print ("Converting video..\n")
# Start converting the video
while cap.isOpened():
# Extract the frame
ret, frame = cap.read()
# Write the results back to output location.
cv2.imwrite(output_loc + "/%#05d.jpg" % (count+1), frame)
count = count + 1
# If there are no more frames left
if (count > (video_length-1)):
# Log the time again
time_end = time.time()

video_to_frames(input_loc, output_loc)
It supports .mts
and normal files like .mp4
and .avi
. Tried and Tested on .mts
files. Works like a Charm.
If you transferred these files through disk or other means, it is likely they were not saved properly.
Simply replace message parameter passed in clientSocket.sendto(message,(serverName, serverPort))
to clientSocket.sendto(message.encode(),(serverName, serverPort))
. Then you would successfully run in in python3
update: 31 Oct 2018, Still usable on laravel 5.7 https://laravel.com/docs/5.7/migrations#modifying-columns
To make some change to existing db, you can modify column type by using change()
in migration.
This is what you could do
Schema::table('orders', function ($table) {
$table->string('category_id')->change();
});
please note you need to add doctrine/dbal dependency to composer.json for more information you can find it here http://laravel.com/docs/5.1/migrations#modifying-columns
if you're still having issues then update to the latest version of Android Studio(its 2.1 as of now), might be it was a bug with older version of Android Studio. Its resolved for me now.
I experienced this exception, and it was also related to ServicePointManager.SecurityProtocol
.
For me, this was because ServicePointManager.SecurityProtocol
had been set to Tls | Tls11
(because of certain websites the application visits with broken TLS 1.2) and upon visiting a TLS 1.2-only website (tested with SSLLabs' SSL Report), it failed.
An option for .NET 4.5 and higher is to enable all TLS versions:
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls
| SecurityProtocolType.Tls11
| SecurityProtocolType.Tls12;
Here i want to show my code how i managed this.
public class CheckPermission {
public Context context;
public static final int PERMISSION_REQUEST_CODE = 200;
public CheckPermission(Context context){
this.context = context;
}
public boolean isPermissionGranted(){
int read_contact = ContextCompat.checkSelfPermission(context.getApplicationContext() , READ_CONTACTS);
int phone = ContextCompat.checkSelfPermission(context.getApplicationContext() , CALL_PHONE);
return read_contact == PackageManager.PERMISSION_GRANTED && phone == PackageManager.PERMISSION_GRANTED;
}
}
Here in this class i want to check permission granted or not. Is not then i will call permission from my MainActivity like
public void requestForPermission() {
ActivityCompat.requestPermissions(MainActivity.this, new String[] {READ_CONTACTS, CALL_PHONE}, PERMISSION_REQUEST_CODE);
}
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
switch (requestCode) {
case PERMISSION_REQUEST_CODE:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (shouldShowRequestPermissionRationale(ACCESS_FINE_LOCATION)) {
showMessageOKCancel("You need to allow access to both the permissions",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(new String[]{Manifest.permission.READ_CONTACTS, Manifest.permission.CALL_PHONE},
PERMISSION_REQUEST_CODE);
}
}
});
return;
}
}
}
}
Now in the onCreate method you need to call requestForPermission() function.
That's it.Also you can request multiple permission at a time.

Quite recently they've added the depends_on
feature.
Edit:
As of compose version 2.1+ till version 3 you can use depends_on
in conjunction with healthcheck
to achieve this:
version: '2.1'
services:
web:
build: .
depends_on:
db:
condition: service_healthy
redis:
condition: service_started
redis:
image: redis
db:
image: redis
healthcheck:
test: "exit 0"
Before version 2.1
You can still use depends_on
, but it only effects the order in which services are started - not if they are ready before the dependant service is started.
It seems to require at least version 1.6.0.
Usage would look something like this:
version: '2'
services:
web:
build: .
depends_on:
- db
- redis
redis:
image: redis
db:
image: postgres
From the docs:
Express dependency between services, which has two effects:
- docker-compose up will start services in dependency order. In the following example, db and redis will be started before web.
- docker-compose up SERVICE will automatically include SERVICE’s dependencies. In the following example, docker-compose up web will also create and start db and redis.
Note: As I understand it, although this does set the order in which containers are loaded. It does not guarantee that the service inside the container has actually loaded.
For example, you postgres container might be up. But the postgres service itself might still be initializing within the container.
I had this same problem, but when running in a jupyter R notebook in an Anaconda environment.
The problem presented in such a way that any R notebook opened would instantly die and would not allow cell execution. The error would show up with each failed automated attempt to start the kernel:
Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]) :
there is no package called ‘Rcpp’
To solve this, I ran as admin/sudo: conda install -c r r-rcpp
, restarted the kernel, and everything was back to normal.
In my case the route in my router was:
Route::post('/new-order', 'Api\OrderController@initiateOrder')->name('newOrder');
and from the client app I was posting the request to:
https://my-domain/api/new-order/
So, because of the trailing slash I got a 405. Hope it helps someone

I've created tutorial on my page https://madebydenis.com/ajax-load-posts-on-wordpress/ about implementing this on Twenty Sixteen theme, so feel free to check it out :)
I've tested this on Twenty Fifteen and it's working, so it should be working for you.
In index.php (assuming that you want to show the posts on the main page, but this should work even if you put it in a page template) I put:
<div id="ajax-posts" class="row">
<?php
$postsPerPage = 3;
$args = array(
'post_type' => 'post',
'posts_per_page' => $postsPerPage,
'cat' => 8
);
$loop = new WP_Query($args);
while ($loop->have_posts()) : $loop->the_post();
?>
<div class="small-12 large-4 columns">
<h1><?php the_title(); ?></h1>
<p><?php the_content(); ?></p>
</div>
<?php
endwhile;
wp_reset_postdata();
?>
</div>
<div id="more_posts">Load More</div>
This will output 3 posts from category 8 (I had posts in that category, so I used it, you can use whatever you want to). You can even query the category you're in with
$cat_id = get_query_var('cat');
This will give you the category id to use in your query. You could put this in your loader (load more div), and pull with jQuery like
<div id="more_posts" data-category="<?php echo $cat_id; ?>">>Load More</div>
And pull the category with
var cat = $('#more_posts').data('category');
But for now, you can leave this out.
Next in functions.php I added
wp_localize_script( 'twentyfifteen-script', 'ajax_posts', array(
'ajaxurl' => admin_url( 'admin-ajax.php' ),
'noposts' => __('No older posts found', 'twentyfifteen'),
));
Right after the existing wp_localize_script
. This will load WordPress own admin-ajax.php so that we can use it when we call it in our ajax call.
At the end of the functions.php file I added the function that will load your posts:
function more_post_ajax(){
$ppp = (isset($_POST["ppp"])) ? $_POST["ppp"] : 3;
$page = (isset($_POST['pageNumber'])) ? $_POST['pageNumber'] : 0;
header("Content-Type: text/html");
$args = array(
'suppress_filters' => true,
'post_type' => 'post',
'posts_per_page' => $ppp,
'cat' => 8,
'paged' => $page,
);
$loop = new WP_Query($args);
$out = '';
if ($loop -> have_posts()) : while ($loop -> have_posts()) : $loop -> the_post();
$out .= '<div class="small-12 large-4 columns">
<h1>'.get_the_title().'</h1>
<p>'.get_the_content().'</p>
</div>';
endwhile;
endif;
wp_reset_postdata();
die($out);
}
add_action('wp_ajax_nopriv_more_post_ajax', 'more_post_ajax');
add_action('wp_ajax_more_post_ajax', 'more_post_ajax');
Here I've added paged key in the array, so that the loop can keep track on what page you are when you load your posts.
If you've added your category in the loader, you'd add:
$cat = (isset($_POST['cat'])) ? $_POST['cat'] : '';
And instead of 8, you'd put $cat
. This will be in the $_POST
array, and you'll be able to use it in ajax.
Last part is the ajax itself. In functions.js I put inside the $(document).ready();
enviroment
var ppp = 3; // Post per page
var cat = 8;
var pageNumber = 1;
function load_posts(){
pageNumber++;
var str = '&cat=' + cat + '&pageNumber=' + pageNumber + '&ppp=' + ppp + '&action=more_post_ajax';
$.ajax({
type: "POST",
dataType: "html",
url: ajax_posts.ajaxurl,
data: str,
success: function(data){
var $data = $(data);
if($data.length){
$("#ajax-posts").append($data);
$("#more_posts").attr("disabled",false);
} else{
$("#more_posts").attr("disabled",true);
}
},
error : function(jqXHR, textStatus, errorThrown) {
$loader.html(jqXHR + " :: " + textStatus + " :: " + errorThrown);
}
});
return false;
}
$("#more_posts").on("click",function(){ // When btn is pressed.
$("#more_posts").attr("disabled",true); // Disable the button, temp.
load_posts();
});
Saved it, tested it, and it works :)
Images as proof (don't mind the shoddy styling, it was done quickly). Also post content is gibberish xD
UPDATE
For 'infinite load' instead on click event on the button (just make it invisible, with visibility: hidden;
) you can try with
$(window).on('scroll', function () {
if ($(window).scrollTop() + $(window).height() >= $(document).height() - 100) {
load_posts();
}
});
This should run the load_posts()
function when you're 100px from the bottom of the page. In the case of the tutorial on my site you can add a check to see if the posts are loading (to prevent firing of the ajax twice), and you can fire it when the scroll reaches the top of the footer
$(window).on('scroll', function(){
if($('body').scrollTop()+$(window).height() > $('footer').offset().top){
if(!($loader.hasClass('post_loading_loader') || $loader.hasClass('post_no_more_posts'))){
load_posts();
}
}
});
Now the only drawback in these cases is that you could never scroll to the value of $(document).height() - 100
or $('footer').offset().top
for some reason. If that should happen, just increase the number where the scroll goes to.
You can easily check it by putting console.log
s in your code and see in the inspector what they throw out
$(window).on('scroll', function () {
console.log($(window).scrollTop() + $(window).height());
console.log($(document).height() - 100);
if ($(window).scrollTop() + $(window).height() >= $(document).height() - 100) {
load_posts();
}
});
And just adjust accordingly ;)
Hope this helps :) If you have any questions just ask.
I like @Alexander-Borisenko's answer, but the localized description was not returned when caught as an Error. It seems that you need to use LocalizedError instead:
struct RuntimeError: LocalizedError
{
let message: String
init(_ message: String)
{
self.message = message
}
public var errorDescription: String?
{
return message
}
}
See this answer for more details.
Just to add to the solution presented, in my case I wanted to fetch multiple data from Firebase for a list of products. Here is how I did it:
useEffect(() => {
const fn = p => firebase.firestore().doc(`products/${p.id}`).get();
const actions = data.occasion.products.map(fn);
const results = Promise.all(actions);
results.then(data => {
const newProducts = [];
data.forEach(p => {
newProducts.push({ id: p.id, ...p.data() });
});
setProducts(newProducts);
});
}, [data]);
Simply remove "DEFINER=your user name
@localhost
" and run the SQL from phpmyadminwill works fine.
You should put your component between an enclosing tag, Which means:
// WRONG!
return (
<Comp1 />
<Comp2 />
)
Instead:
// Correct
return (
<div>
<Comp1 />
<Comp2 />
</div>
)
Edit: Per Joe Clay's comment about the Fragments API
// More Correct
return (
<React.Fragment>
<Comp1 />
<Comp2 />
</React.Fragment>
)
// Short syntax
return (
<>
<Comp1 />
<Comp2 />
</>
)
The current best way to do this is to use df.to_string()
:
with open(writePath, 'a') as f:
f.write(
df.to_string(header = False, index = False)
)
Will output the following
18 55 1 70
18 55 2 67
18 57 2 75
18 58 1 35
19 54 2 70
This method also lets you easily choose which columns to print with the columns
attribute, lets you keep the column, index labels if you wish, and has other attributes for spacing ect.

DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;

android:id="@+id/nav_test1"
android:title="@string/test1" />
<item

so first menu is highlight and show as default menu.
Make sure that you have php-xml module installed and enabled in php.ini
.
You can also change response format to json which is easier to handle. In that case you have to only add &format=json
to url query string.
$rest_url = "http://api.facebook.com/restserver.php?method=links.getStats&format=json&urls=".urlencode($source_url);
And then use json_decode()
to retrieve data in your script:
$result = json_decode($content, true);
$fb_like_count = $result['like_count'];
Go to D:Android sdk\Android SDK and click on SDK Manager and check whether Build Tools are installed or not if they are not installed then install those tools
I have been having this issue with SweetAlert2 as well. SA2 differs from 1 and puts everything inside the result object. The following above can be accomplished with the following code.
Swal.fire({
title: 'A cool title',
icon: 'info',
confirmButtonText: 'Log in'
}).then((result) => {
if (result['isConfirmed']){
// Put your function here
}
})
Everything placed inside the then result will run. Result holds a couple of parameters which can be used to do the trick. Pretty simple technique. Not sure if it works the same on SweetAlert1 but I really wouldn't know why you would choose that one above the newer version.
I believe all the existing answers contain the relevant information, but I would like to summarize.
The response object that is returned by requests
get and post operations contains two useful attributes:
response.text
- Contains str
with the response text.response.content
- Contains bytes
with the raw response content.You should choose one or other of these attributes depending on the type of response you expect.
response.text
response.content
.When writing responses to file you need to use the open function with the appropriate file write mode.
"w"
- plain write mode."wb"
- binary write mode.# Request the HTML for this web page:
response = requests.get("https://stackoverflow.com/questions/31126596/saving-response-from-requests-to-file")
with open("response.txt", "w") as f:
f.write(response.text)
# Request the profile picture of the OP:
response = requests.get("https://i.stack.imgur.com/iysmF.jpg?s=32&g=1")
with open("response.jpg", "wb") as f:
f.write(response.content)
The original code should work by using wb
and response.content
:
import requests
files = {'f': ('1.pdf', open('1.pdf', 'rb'))}
response = requests.post("https://pdftables.com/api?&format=xlsx-single",files=files)
response.raise_for_status() # ensure we notice bad responses
file = open("out.xls", "wb")
file.write(response.content)
file.close()
But I would go further and use the with
context manager for open
.
import requests
with open('1.pdf', 'rb') as file:
files = {'f': ('1.pdf', file)}
response = requests.post("https://pdftables.com/api?&format=xlsx-single",files=files)
response.raise_for_status() # ensure we notice bad responses
with open("out.xls", "wb") as file:
file.write(response.content)
you are calling the context of not existing activity...so just replace your code in onClick(View v) as Intent intent=new Intent(this,Katra_home.class); startActivity(intent); it will definitely works....
Delete platforms/android folder and try to rebuild. That helped me a lot.

You can try this library. This is a wrapper for android default snackbar. https://github.com/ChathuraHettiarachchi/CSnackBar
Snackbar.with(this,null)
.type(Type.SUCCESS)
.message("Profile updated successfully!")
.duration(Duration.SHORT)
.show();
This contains multiple types of snackbar and even a customview intergrated snackbar
This error also happens if you have got the order of your components wrong.
Example: this wrong:
<ComponentA>
<ComponentB>
</ComponentA>
</ComponentB>
correct way:
<ComponentA>
<ComponentB>
</ComponentB>
</ComponentA>
I was also disappointed by the lack of type a function can throw, but I get it now thanks to @rickster and I'll summarize it like this: let's say we could specify the type a function throws, we would have something like this:
enum MyError: ErrorType { case ErrorA, ErrorB }
func myFunctionThatThrows() throws MyError { ...throw .ErrorA...throw .ErrorB... }
do {
try myFunctionThatThrows()
}
case .ErrorA { ... }
case .ErrorB { ... }
The problem is that even if we don't change anything in myFunctionThatThrows, if we just add an error case to MyError:
enum MyError: ErrorType { case ErrorA, ErrorB, ErrorC }
we are screwed because our do/try/catch is no longer exhaustive, as well as any other place where we called functions that throw MyError
I would advise against restricting the SecurityProtocol to TLS 1.1.
The recommended solution is to use
System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12 | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls
Another option is add the following Registry key:
Key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\.NETFramework\v4.0.30319
Value: SchUseStrongCrypto
It is worth noting that .NET 4.6 will use the correct protocol by default and does not require either solution.
Using NewRequest
just to create an URL is an overkill. Use the net/url
package:
package main
import (
"fmt"
"net/url"
)
func main() {
base, err := url.Parse("http://www.example.com")
if err != nil {
return
}
// Path params
base.Path += "this will get automatically encoded"
// Query params
params := url.Values{}
params.Add("q", "this will get encoded as well")
base.RawQuery = params.Encode()
fmt.Printf("Encoded URL is %q\n", base.String())
}

If using Nginx
and getting a similar problem, then this might help:
Scan your domain on this sslTesturl, and see if the connection is allowed for your device version.
If lower version devices(like < Android 4.4.2 etc) are not able to connect due to TLS support, then try adding this to your Nginx config file,
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
The simplest way to get an input box is with the Read-Host cmdlet and -AsSecureString parameter.
$us = Read-Host 'Enter Your User Name:' -AsSecureString
$pw = Read-Host 'Enter Your Password:' -AsSecureString
This is especially useful if you are gathering login info like my example above. If you prefer to keep the variables obfuscated as SecureString objects you can convert the variables on the fly like this:
[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))
[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($pw))
If the info does not need to be secure at all you can convert it to plain text:
$user = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))
Read-Host and -AsSecureString appear to have been included in all PowerShell versions (1-6) but I do not have PowerShell 1 or 2 to ensure the commands work identically. https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/read-host?view=powershell-3.0
You can use android:stopWithTask="false"

For all the Windows users, try moving your codebase to a shorter windows path for eg: C:/myProj
Deeply nested Maven jar files can create a longer file path in windows. Since windows OS, by default, limits the file path length to 260 characters, it throws exception when trying to read a file located at a path that becomes more than 260 characters.
You can change this default to increase this limit to more than 260 chracters. Search around the web and you will find many posts on how to do that.
You can face similar problem while using npm packages also.
Make sure that while using : Button "varName" =findViewById("btID"); you put in the right "btID". I accidentally put in the id of a button from another similar activity and it showed the same error. Hope it helps.
For beginners: To create your .bash_profile
file in your home directory on MacOS, run:
nano ~/.bash_profile
Then you can paste in the following:
https://gist.github.com/mocon/0baf15e62163a07cb957888559d1b054
As you can see, it includes some example aliases and an environment variable at the bottom.
One you're done making your changes, follow the instructions at the bottom of the Nano editor window to WriteOut (Ctrl-O
) and Exit (Ctrl-X
). Then quit your Terminal and reopen it, and you will be able to use your newly defined aliases and environment variables.
Guzzle example:
use GuzzleHttp\Client;
use GuzzleHttp\RequestOptions;
$token = 'your_token';
$httpClient = new Client();
$response = $httpClient->get(
'https://httpbin.org/bearer',
[
RequestOptions::HEADERS => [
'Accept' => 'application/json',
'Authorization' => 'Bearer ' . $token,
]
]
);
print_r($response->getBody()->getContents());

I was having this same problem in a web app using Microsoft Visual Studio 2019, Asp.Net 3.1 and Bootstrap 4.5. I had a modal form open to add a new staff person (only a few input fields) and the Add Staff button would invoke an ajax call to create the staff records in the database. Upon successful return the code would refresh the partial razor page of staff (so the new staff person would appear in the list).
Just before the refresh I would close the Add Staff modal and display a Please Wait modal which only had a bootstrap spinner button on it. What happened is that the Please Wait modal would stay displayed and not close after the staff refresh and the modal('hide') function on this modal was called. Some times the modal would disappear but the modal backdrop would remain effectively locking the Staff List form.
Since Bootstrap has issues with multiple modals open at once, I thought maybe the Add Staff modal was still open when the Please Wait modal was displayed and this was causing problems. I made a function to display the Please Wait modal and do the refresh, and called it using the Javascript function setTimeout() to wait 1/2 second after closing/hiding the Add Staff modal:
//hide the modal form
$("#addNewStaffModal").modal('hide');
setTimeout(RefreshStaffListAfterAddingStaff, 500); //wait for 1/2 second
Here is the code for the refresh function:
function RefreshStaffListAfterAddingStaff() {
// refresh the staff list in our partial view
//show the please wait message
$('#PleaseWaitModal').modal('show');
//refresh the partial view
$('#StaffAccountsPartialView').load('StaffAccounts?handler=StaffAccountsPartial',
function (data, status, jqXGR) {
//hide the wait modal
$('#PleaseWaitModal').modal('hide');
// enable all the fields on our form
$("#StaffAccountsForm :input").prop("disabled", false);
//scroll to the top of the staff list window
window.scroll({
top: 0,
left: 0,
behavior: 'smooth'
});
});
}
This seems to have totally solved my problem!
TLS 1.1 and TLS 1.2 are supported since OpenSSL 1.0.1

You should consider an upgrade.
CellType cell = row.getCell(j).getCellTypeEnum();
switch(cell) {
case NUMERIC:
intVal = row.getCell(j).getNumericCellValue();
System.out.print(intVal);
break;
case STRING:
stringVal = row.getCell(j).getStringCellValue();
System.out.print(stringVal);
break;
}
Another Default Method:
Try pressing the ending bracket key )
again. It will move your cursor to the end of the brackets. I think it's a good practice to have the habit of typing both brackets.
The best way for me was to put it in a hidden div in php blade

There is no way in Selenium to read the request or response headers. You could do it by instructing your browser to connect through a proxy that records this kind of information.
The usual way to change the user agent for Firefox is to set the variable "general.useragent.override"
in your Firefox profile. Note that this is independent from Selenium.
You can direct Selenium to use a profile different from the default one, like this:
from selenium import webdriver
profile = webdriver.FirefoxProfile()
profile.set_preference("general.useragent.override", "whatever you want")
driver = webdriver.Firefox(profile)
With Chrome, what you want to do is use the user-agent
command line option. Again, this is not a Selenium thing. You can invoke Chrome at the command line with chrome --user-agent=foo
to set the agent to the value foo
.
With Selenium you set it like this:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
opts = Options()
opts.add_argument("user-agent=whatever you want")
driver = webdriver.Chrome(chrome_options=opts)
Both methods above were tested and found to work. I don't know about other browsers.
Selenium does not have methods to query the user agent from an instance of WebDriver
. Even in the case of Firefox, you cannot discover the default user agent by checking what general.useragent.override
would be if not set to a custom value. (This setting does not exist before it is set to some value.)
Once the browser is started, however, you can get the user agent by executing:
agent = driver.execute_script("return navigator.userAgent")
The agent
variable will contain the user agent.
First redirect stderr to stdout — the pipe; then redirect stdout to /dev/null
(without changing where stderr is going):
command 2>&1 >/dev/null | grep 'something'
For the details of I/O redirection in all its variety, see the chapter on Redirections in the Bash reference manual.
Note that the sequence of I/O redirections is interpreted left-to-right, but pipes are set up before the I/O redirections are interpreted. File descriptors such as 1 and 2 are references to open file descriptions. The operation 2>&1
makes file descriptor 2 aka stderr refer to the same open file description as file descriptor 1 aka stdout is currently referring to (see dup2()
and open()
). The operation >/dev/null
then changes file descriptor 1 so that it refers to an open file description for /dev/null
, but that doesn't change the fact that file descriptor 2 refers to the open file description which file descriptor 1 was originally pointing to — namely, the pipe.
Arrays are special objects in java, they have a simple attribute named length
which is final
.
There is no "class definition" of an array (you can't find it in any .class file), they're a part of the language itself.
10.7. Array Members
The members of an array type are all of the following:
- The
public
final
fieldlength
, which contains the number of components of the array.length
may be positive or zero.The
public
methodclone
, which overrides the method of the same name in classObject
and throws no checked exceptions. The return type of theclone
method of an array typeT[]
isT[]
.A clone of a multidimensional array is shallow, which is to say that it creates only a single new array. Subarrays are shared.
- All the members inherited from class
Object
; the only method ofObject
that is not inherited is itsclone
method.
Resources:
The standard associative-container erase idiom:
for (auto it = m.cbegin(); it != m.cend() /* not hoisted */; /* no increment */)
{
if (must_delete)
{
m.erase(it++); // or "it = m.erase(it)" since C++11
}
else
{
++it;
}
}
Note that we really want an ordinary for
loop here, since we are modifying the container itself. The range-based loop should be strictly reserved for situations where we only care about the elements. The syntax for the RBFL makes this clear by not even exposing the container inside the loop body.
Edit. Pre-C++11, you could not erase const-iterators. There you would have to say:
for (std::map<K,V>::iterator it = m.begin(); it != m.end(); ) { /* ... */ }
Erasing an element from a container is not at odds with constness of the element. By analogy, it has always been perfectly legitimate to delete p
where p
is a pointer-to-constant. Constness does not constrain lifetime; const values in C++ can still stop existing.
The function move.CompleteMove(events)
that you use within your class probably doesn't contain a return
statement. So nothing is returned to self.values
(==> None). Use return
in move.CompleteMove(events)
to return whatever you want to store in self.values
and it should work. Hope this helps.
Here is a workaround using a flag:
//outside your event or method, but inside your class
private bool IsExecuted = false;
private async Task MethodA()
{
//Do Stuff Here
IsExecuted = true;
}
.
.
.
//Inside your event or method
{
await MethodA();
while (!isExecuted) Thread.Sleep(200); // <-------
await MethodB();
}
Have a look at the GROUP_CONCAT project on Github, I think I does exactly what you are searching for:
This project contains a set of SQLCLR User-defined Aggregate functions (SQLCLR UDAs) that collectively offer similar functionality to the MySQL GROUP_CONCAT function. There are multiple functions to ensure the best performance based on the functionality required...
A quick note: Assume.assumeTrue(condition)
ignores rest of the steps but passes the test.
To fail the test, use org.junit.Assert.fail()
inside the conditional statement. Works same like Assume.assumeTrue()
but fails the test.
You could use CSS to do that, but it wouldn't be supported in IE8-. You can use some site like http://borderradius.com to come up with actual CSS you'd use, which would look something like this (again, depending on how many browsers you're trying to support):
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;
Alternately, it could also be done as:
<?php
include("ckeditor/ckeditor.php");
$CKeditor = new CKeditor();
$CKeditor->BasePath = 'ckeditor/';
$CKeditor->editor('editor1');
?>
Note that the last line is having 'editor1' as name, it could be changed as per your requirement.

The problem is that your controller expect a parameter hasId=false or hasId=true, but you are not passing that. Your hidden field has the id hasId but is passed as hasCustomerName, so no mapping matches.
Either change the path of the hidden field to hasId or the mapping parameter to expect hasCustomerName=true or hasCustomerName=false.

I used the following code to listen to changes to an array.
/* @arr array you want to listen to
@callback function that will be called on any change inside array
*/
function listenChangesinArray(arr,callback){
// Add more methods here if you want to listen to them
['pop','push','reverse','shift','unshift','splice','sort'].forEach((m)=>{
arr[m] = function(){
var res = Array.prototype[m].apply(arr, arguments); // call normal behaviour
callback.apply(arr, arguments); // finally call the callback supplied
return res;
}
});
}
Hope this was useful :)
Try this:
.navbar {
position: relative;
}
.brand {
position: absolute;
left: 50%;
margin-left: -50px !important; /* 50% of your logo width */
display: block;
}
Centering your logo by 50% and minus half of your logo width so that it won't have problem when zooming in and out.

java provides support for Unicode i.e it supports all world wide alphabets. Hence the size of char in java is 2 bytes. And range is 0 to 65535.
@synthesize will generate getter and setter methods for your property. @dynamic just tells the compiler that the getter and setter methods are implemented not by the class itself but somewhere else (like the superclass or will be provided at runtime).
Uses for @dynamic are e.g. with subclasses of NSManagedObject
(CoreData) or when you want to create an outlet for a property defined by a superclass that was not defined as an outlet.
@dynamic also can be used to delegate the responsibility of implementing the accessors. If you implement the accessors yourself within the class then you normally do not use @dynamic.
Super class:
@property (nonatomic, retain) NSButton *someButton;
...
@synthesize someButton;
Subclass:
@property (nonatomic, retain) IBOutlet NSButton *someButton;
...
@dynamic someButton;
This is how you create a borderless (flat) button programmatically without using XML
ContextThemeWrapper myContext = new ContextThemeWrapper(this.getActivity(),
R.style.Widget_AppCompat_Button_Borderless_Colored);
Button myButton = new Button(myContext, null,
R.style.Widget_AppCompat_Button_Borderless_Colored);
For symfony 2.6 and above we can use
{{ app.user.getFirstname() }}
as app.security global variable for Twig template has been deprecated and will be removed from 3.0
more info:
http://symfony.com/blog/new-in-symfony-2-6-security-component-improvements
and see the global variables in

I used a very similar method to @bott, but I modified it a little bit to make there be no need to resize the image:
BufferedImage img = null;
try {
img = ImageIO.read(new File("image.jpg"));
} catch (IOException e) {
e.printStackTrace();
}
Image dimg = img.getScaledInstance(800, 508, Image.SCALE_SMOOTH);
ImageIcon imageIcon = new ImageIcon(dimg);
setContentPane(new JLabel(imageIcon));
Works every time. You can also get the width and height of the jFrame and use that in place of the 800 and 508 respectively.
Express.js is a Node.js web application server framework, designed for building single-page, multi-page, and hybrid web applications. It is the de facto standard server framework for node.js.
Frameworks built on Express.
Several popular Node.js frameworks are built on Express:
LoopBack: Highly-extensible, open-source Node.js framework for quickly creating dynamic end-to-end REST APIs.
Sails: MVC framework for Node.js for building practical, production-ready apps.
Kraken: Secure and scalable layer that extends Express by providing structure and convention.
MEAN: Opinionated fullstack JavaScript framework that simplifies and accelerates web application development.
Express adds dead simple routing and support for Connect middleware, allowing many extensions and useful features.
For example,
have a look at this Regex & PHP - isolate src attribute from img tag
perhaps you can walk through the DOM and get the desired attributes. It works fine for me, getting attributes from the body-tag
I was getting this error on Vue 3. It was because defineComponent
must be imported like this:
<script lang="ts">
import { defineComponent } from "vue";
export default defineComponent({
name: "HelloWorld",
props: {
msg: String,
},
created() {
this.testF();
},
methods: {
testF() {
console.log("testF");
},
},
});
</script>
I actually had this identical issue with the inverse solution. I had upgraded a .NET project to .NET 4.0 and then reverted back to .NET 3.5. The app.config in my project continued to have the following which was causing the above error in question:
<startup>
<supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>
</startup>
The solution to solve the error for this was to revert it back to the proper 2.0 reference as follows:
<startup>
<supportedRuntime version="v2.0.50727"/>
</startup>
So if a downgrade is producing the above error, you might need to back up the .NET Framework supported version.
You can do this by providing in class numbers
:
By the way, there is a strong convention that Java class names are uppercased.
Case 1 (simple getter):
public class Numbers {
private List<Integer> list;
public List<Integer> getList() { return list; }
...
}
Case 2 (non-modifiable wrapper):
public class Numbers {
private List<Integer> list;
public List<Integer> getList() { return Collections.unmodifiableList( list ); }
...
}
Case 3 (specific methods):
public class Numbers {
private List<Integer> list;
public void addToList( int i ) { list.add(i); }
public int getValueAtIndex( int index ) { return list.get( index ); }
...
}
You can check the availability of the view in various ways
FOR SQL SERVER
use sys.objects
IF EXISTS(
SELECT 1
FROM sys.objects
WHERE OBJECT_ID = OBJECT_ID('[schemaName].[ViewName]')
AND Type_Desc = 'VIEW'
)
BEGIN
PRINT 'View Exists'
END
use sysobjects
IF NOT EXISTS (
SELECT 1
FROM sysobjects
WHERE NAME = '[schemaName].[ViewName]'
AND xtype = 'V'
)
BEGIN
PRINT 'View Exists'
END
use sys.views
IF EXISTS (
SELECT 1
FROM sys.views
WHERE OBJECT_ID = OBJECT_ID(N'[schemaName].[ViewName]')
)
BEGIN
PRINT 'View Exists'
END
use INFORMATION_SCHEMA.VIEWS
IF EXISTS (
SELECT 1
FROM INFORMATION_SCHEMA.VIEWS
WHERE table_name = 'ViewName'
AND table_schema = 'schemaName'
)
BEGIN
PRINT 'View Exists'
END
use OBJECT_ID
IF EXISTS(
SELECT OBJECT_ID('ViewName', 'V')
)
BEGIN
PRINT 'View Exists'
END
use sys.sql_modules
IF EXISTS (
SELECT 1
FROM sys.sql_modules
WHERE OBJECT_ID = OBJECT_ID('[schemaName].[ViewName]')
)
BEGIN
PRINT 'View Exists'
END
The best solution would be to go to http://projects.eclipse.org/projects/tools.pdt/downloads where you will find the URL to the most updated PDT, as most of the URLS listed above are hitting a 404. Then pasting the URL to eclipse.
Assuming you mean "list" where you say "array", you can do
if item in my_list:
# whatever
This works for any collection, not just for lists. For dictionaries, it checks whether the given key is present in the dictionary.
You need to add width: 0
to make columns equal if contents of the items make it grow bigger.
.item {
flex: 1 1 0;
width: 0;
}
Use logging:
import unittest
import logging
import inspect
import os
logging_level = logging.INFO
try:
log_file = os.environ["LOG_FILE"]
except KeyError:
log_file = None
def logger(stack=None):
if not hasattr(logger, "initialized"):
logging.basicConfig(filename=log_file, level=logging_level)
logger.initialized = True
if not stack:
stack = inspect.stack()
name = stack[1][3]
try:
name = stack[1][0].f_locals["self"].__class__.__name__ + "." + name
except KeyError:
pass
return logging.getLogger(name)
def todo(msg):
logger(inspect.stack()).warning("TODO: {}".format(msg))
def get_pi():
logger().info("sorry, I know only three digits")
return 3.14
class Test(unittest.TestCase):
def testName(self):
todo("use a better get_pi")
pi = get_pi()
logger().info("pi = {}".format(pi))
todo("check more digits in pi")
self.assertAlmostEqual(pi, 3.14)
logger().debug("end of this test")
pass
Usage:
# LOG_FILE=/tmp/log python3 -m unittest LoggerDemo
.
----------------------------------------------------------------------
Ran 1 test in 0.047s
OK
# cat /tmp/log
WARNING:Test.testName:TODO: use a better get_pi
INFO:get_pi:sorry, I know only three digits
INFO:Test.testName:pi = 3.14
WARNING:Test.testName:TODO: check more digits in pi
If you do not set LOG_FILE
, logging will got to stderr
.
current package : com.company.name
New package : com.mycomapny.name
Steps: 1) Suppose you are at this screen which is shown below.
2) Open project pane and click on settings icon.
3) Deselect Compact Empty Middle Packages.
4) Then your package is now broken into individual parts as shown below .
5) right click on "company" select Refactor -> select rename ->rename directory.
6) Now your "company" has been changed to new "mycomapny" and changes were reflected as shown in below figure.
7) Now change the package name in AndroidManifest.xml file .
8) Open app level build.gradle and change package name .
9) you will get errors as Cannot resolve symbol "R" .
10) Remove line which gives this error and studio will import new R file automatically.
11) If you have multiple files then use find and replace option by pressing " Cntrl+Shift+R "
Or " Select Edit->Find->Replace in path.."
12) select Replace All.
You could try using Insight a graphical front-end for gdb written by Red Hat Or if you use GNOME desktop environment, you can also try Nemiver.
If you need to specify the exact charactor length, we have to avoid values with 0 in-front.
Final String representation must have that exact character length.
String GenerateRandomNumber(int charLength) {
return String.valueOf(charLength < 1 ? 0 : new Random()
.nextInt((9 * (int) Math.pow(10, charLength - 1)) - 1)
+ (int) Math.pow(10, charLength - 1));
}
Create an array with the number of items you want first and then convert the array in to a List.
int[] fakeArray = new int[10];
List<int> list = fakeArray.ToList();
It happens because you have not installed the minSdkVersion or targetSdkVersion in you’re computer. I've tested it right now.
For example, if you have those lines in your Manifest.xml:
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
And you have installed only the API17 in your computer, it will report you an error. If you want to test it, try installing the other API version (in this case, API 8).
Even so, it's not an important error. It doesn't mean that your app is wrong.
Sorry about my expression. English is not my language. Bye!

I've found also a nice and simple way to address hostsvars right on one of Ansible's Github issues
Looks like you can do this as well:
- debug:
msg: "{{ ansible_ssh_host }}"
This is a BUG reported in launchpad, but there is a workaround :
Run this to see where these files are located
$ find /usr/ -name crti*
/usr/lib/x86_64-linux-gnu/crti.o
then add this path to LIBRARY_PATH variable
$ export LIBRARY_PATH=/usr/lib/x86_64-linux-gnu:$LIBRARY_PATH
IF EXISTS (SELECT 1 FROM Table WHERE FieldValue='')
BEGIN
SELECT TableID FROM Table WHERE FieldValue=''
END
ELSE
BEGIN
INSERT INTO TABLE(FieldValue) VALUES('')
SELECT SCOPE_IDENTITY() AS TableID
END
See here for more information on IF ELSE
Note: written without a SQL Server install handy to double check this but I think it is correct
Also, I've changed the EXISTS bit to do SELECT 1 rather than SELECT * as you don't care what is returned within an EXISTS, as long as something is I've also changed the SCOPE_IDENTITY() bit to return just the identity assuming that TableID is the identity column
Dim ws as Object
Set ws = Worksheets("name")
when declaring the worksheet as worksheet instead of an ojbect I had issues working with OptionButtons (Active X) in this worksheet (I guess the same will be with any Active-X element. When declared as object everything works fine.
If your $location.search()
is not working, then make sure you have the following:
1) html5Mode(true)
is configured in app's module config
appModule.config(['$locationProvider', function($locationProvider) {
$locationProvider.html5Mode(true);
}]);
2) <base href="/">
is present in your HTML
<head>
<base href="/">
...
</head>
References:
While the other answers have not worked for me in all situations, the best solution I could find (working with POST
as well), taken from here:
curl -vs 'https://some-site.com' 1> /dev/null
Prior to version 1.14, wget timeout arguments were not adhered to if downloading over https due to a bug.
Since phone numbers must conform to a pattern, you can use regular expressions to match the entered phone number against the pattern you define in regexp.
php has both ereg and preg_match() functions. I'd suggest using preg_match() as there's more documentation for this style of regex.
An example
$phone = '000-0000-0000';
if(preg_match("/^[0-9]{3}-[0-9]{4}-[0-9]{4}$/", $phone)) {
// $phone is valid
}
I think this is what you need if I'm understanding you correctly:
<div id="wrapperHeader">
<div id="header">
<img src="images/logo.png" alt="logo" />
</div>
</div>
div#wrapperHeader {
width:100%;
height;200px; /* height of the background image? */
background:url(images/header.png) repeat-x 0 0;
text-align:center;
}
div#wrapperHeader div#header {
width:1000px;
height:200px;
margin:0 auto;
}
div#wrapperHeader div#header img {
width:; /* the width of the logo image */
height:; /* the height of the logo image */
margin:0 auto;
}
Convert.ChangeType()
doesn't correctly handle nullable types or enumerations in .NET 2.0 BCL (I think it's fixed for BCL 4.0 though). Rather than make the outer implementation more complex, make the converter do more work for you. Here's an implementation I use:
public static class Converter
{
public static T ConvertTo<T>(object value)
{
return ConvertTo(value, default(T));
}
public static T ConvertTo<T>(object value, T defaultValue)
{
if (value == DBNull.Value)
{
return defaultValue;
}
return (T) ChangeType(value, typeof(T));
}
public static object ChangeType(object value, Type conversionType)
{
if (conversionType == null)
{
throw new ArgumentNullException("conversionType");
}
// if it's not a nullable type, just pass through the parameters to Convert.ChangeType
if (conversionType.IsGenericType && conversionType.GetGenericTypeDefinition().Equals(typeof(Nullable<>)))
{
// null input returns null output regardless of base type
if (value == null)
{
return null;
}
// it's a nullable type, and not null, which means it can be converted to its underlying type,
// so overwrite the passed-in conversion type with this underlying type
conversionType = Nullable.GetUnderlyingType(conversionType);
}
else if (conversionType.IsEnum)
{
// strings require Parse method
if (value is string)
{
return Enum.Parse(conversionType, (string) value);
}
// primitive types can be instantiated using ToObject
else if (value is int || value is uint || value is short || value is ushort ||
value is byte || value is sbyte || value is long || value is ulong)
{
return Enum.ToObject(conversionType, value);
}
else
{
throw new ArgumentException(String.Format("Value cannot be converted to {0} - current type is " +
"not supported for enum conversions.", conversionType.FullName));
}
}
return Convert.ChangeType(value, conversionType);
}
}
Then your implementation of GetQueryString<T> can be:
public static T GetQueryString<T>(string key)
{
T result = default(T);
string value = HttpContext.Current.Request.QueryString[key];
if (!String.IsNullOrEmpty(value))
{
try
{
result = Converter.ConvertTo<T>(value);
}
catch
{
//Could not convert. Pass back default value...
result = default(T);
}
}
return result;
}
Setting android:layout_gravity="bottom|right"
worked for me
when nothing else works, open a new terminal then:
$ ps aux | grep attach
username <pid_here> .............. 0:00 docker attach <CONTAINER_HASH_HERE>
username <another_pid> .............. 0:00 grep --color=auto attach
$ kill -9 <pid_here>
Instead of having static methods and passing around a pointer to the class instance, you could use functionality in the new C++11 standard: std::function
and std::bind
:
#include <functional>
class EventHandler
{
public:
void addHandler(std::function<void(int)> callback)
{
cout << "Handler added..." << endl;
// Let's pretend an event just occured
callback(1);
}
};
The addHandler
method now accepts a std::function
argument, and this "function object" have no return value and takes an integer as argument.
To bind it to a specific function, you use std::bind
:
class MyClass
{
public:
MyClass();
// Note: No longer marked `static`, and only takes the actual argument
void Callback(int x);
private:
int private_x;
};
MyClass::MyClass()
{
using namespace std::placeholders; // for `_1`
private_x = 5;
handler->addHandler(std::bind(&MyClass::Callback, this, _1));
}
void MyClass::Callback(int x)
{
// No longer needs an explicit `instance` argument,
// as `this` is set up properly
cout << x + private_x << endl;
}
You need to use std::bind
when adding the handler, as you explicitly needs to specify the otherwise implicit this
pointer as an argument. If you have a free-standing function, you don't have to use std::bind
:
void freeStandingCallback(int x)
{
// ...
}
int main()
{
// ...
handler->addHandler(freeStandingCallback);
}
Having the event handler use std::function
objects, also makes it possible to use the new C++11 lambda functions:
handler->addHandler([](int x) { std::cout << "x is " << x << '\n'; });
try this
Intent a = new Intent(Intent.ACTION_MAIN);
a.addCategory(Intent.CATEGORY_HOME);
a.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(a);
2020 answer since I was missing the functionality to automatically delete a parameter, so:
Based on my favorite answer https://stackoverflow.com/a/20420424/6284674 : I combined it with the ability to:
automatically delete an URL param if the value if null
or ''
based on answer https://stackoverflow.com/a/25214672/6284674
optionally push the updated URL directly in the window.location bar
IE support since it's only using regex and no URLSearchParams
JSfiddle: https://jsfiddle.net/MickV/zxc3b47u/
function replaceUrlParam(url, paramName, paramValue){
if(paramValue == null || paramValue == "")
return url
.replace(new RegExp('[?&]' + paramValue + '=[^&#]*(#.*)?$'), '$1')
.replace(new RegExp('([?&])' + paramValue + '=[^&]*&'), '$1');
url = url.replace(/\?$/,'');
var pattern = new RegExp('\\b('+paramName+'=).*?(&|$)')
if(url.search(pattern)>=0){
return url.replace(pattern,'$1' + paramValue + '$2');
}
return url + (url.indexOf('?')>0 ? '&' : '?') + paramName + '=' + paramValue
}
// Orginal URL (default jsfiddle console URL)

If someone wants the answer, I think I just got it. Try this:
override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
return UIInterfaceOrientationMask.Portrait.toRaw().hashValue | UIInterfaceOrientationMask.PortraitUpsideDown.toRaw().hashValue
}
Hope it helps !
EDIT :
To force rotation, use the following code :
let value = UIInterfaceOrientation.LandscapeRight.rawValue
UIDevice.currentDevice().setValue(value, forKey: "orientation")
It works for iOS 7 & 8 !
You can do this with html5 very easily:
var link = document.createElement('a');
link.href = "/WWW/test.pdf";
link.download = "file_" + new Date() + ".pdf";
link.click();
link.remove()

os.chdir(<module_path>)
import <module>
os.chdir(cwd)

Node.js uses libuv behind the scenes. libuv has a thread pool (of size 4 by default). Therefore Node.js does use threads to achieve concurrency.
However, your code runs on a single thread (i.e., all of the callbacks of Node.js functions will be called on the same thread, the so called loop-thread or event-loop). When people say "Node.js runs on a single thread" they are really saying "the callbacks of Node.js run on a single thread".
Great answer above. Another way is to use the great yaml jq wrapper tool, yq at https://github.com/kislyuk/yq
Save your JSON example to a file, say ex.json and then
yq -y '.' ex.json

This is a good way to do it:
<?php
if (!(isset($_SERVER['HTTPS']) && ($_SERVER['HTTPS'] == 'on' ||
$_SERVER['HTTPS'] == 1) ||
isset($_SERVER['HTTP_X_FORWARDED_PROTO']) &&
$_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https'))
{
$redirect = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
header('HTTP/1.1 301 Moved Permanently');
header('Location: ' . $redirect);
exit();
}
?>
You just need to add this line to the window there:
exec (your stored proc name) (and possibly add parameters)
What is your stored proc called, and what parameters does it expect?
There should also be a YEAR().
As for comparing, you could compare dates that are the first days of those years and months, or you could convert the year/month pair into a number suitable for comparison (i.e. bigger = later). (Exercise left to the reader. For hints, read about the ISO date format.)
Or you could use multiple comparisons (i.e. years first, then months).
To keep it basic, I used a loop and something like this to get you started (my index are datetimes):
import pandas as pd
import datetime as dt
#populate your dataframe: "df"
#...
df[df.index<(df.index[0]+dt.timedelta(hours=1))] #gives you a slice. you can then take .sum() .mean(), whatever
and then you can run functions on that slice. You can see how adding an iterator to make the start of the window something other than the first value in your dataframes index would then roll the window (you could use a > rule for the start as well for example).
Note, this may be less efficient for SUPER large data or very small increments as your slicing may become more strenuous (works for me well enough for hundreds of thousands of rows of data and several columns though for hourly windows across a few weeks)
Adding to all the answers already available for this question, I would like to add the steps I followed to install Python3 on AWS EC2 instance running CentOS 7. You can find the entire details at this link.
https://aws-labs.com/install-python-3-centos-7-2/
First, we need to enable SCL. SCL is a community project that allows you to build, install, and use multiple versions of software on the same system, without affecting system default packages.
sudo yum install centos-release-scl
Now that we have SCL repository, we can install the python3
sudo yum install rh-python36
To access Python 3.6 you need to launch a new shell instance using the Software Collection scl tool:
scl enable rh-python36 bash
If you check the Python version now you’ll notice that Python 3.6 is the default version
python --version
It is important to point out that Python 3.6 is the default Python version only in this shell session. If you exit the session or open a new session from another terminal Python 2.7 will be the default Python version.
Now, Install the python development tools by typing:
sudo yum groupinstall ‘Development Tools’
Now create a virtual environment so that the default python packages don't get messed up.
mkdir ~/my_new_project
cd ~/my_new_project
python -m venv my_project_venv
To use this virtual environment,
source my_project_venv/bin/activate
Now, you have your virtual environment set up with python3.
In Sharepoint Server 2010 they are stored here:
"c:\Program Files\Common Files\Microsoft Shared\web server extensions\14\LOGS"
To view them you can use ULS Viewer by Microsoft (unsupported). http://ulsviewer.codeplex.com/
When you opening modal on a tag and want show tooltip and if you implement tooltip inside tag it will show tooltip nearby tag. like this
I will suggest that use div outside a tag and use "display: inline-block;"
<div data-toggle="tooltip" title="" data-original-title="Add" style=" display inline-block;">
<a class="btn btn-primary" data-toggle="modal" data-target="#myModal" onclick="setSelectedRoleId(6)">
<span class="fa fa-plus"></span>
</a>
</div>
To round out the possibilities, you can use writeLines()
with sink()
, if you want:
> sink("tempsink", type="output")
> writeLines("Hello\nWorld")
> sink()
> file.show("tempsink", delete.file=TRUE)
Hello
World
To me, it always seems most intuitive to use print()
, but if you do that the output won't be what you want:
...
> print("Hello\nWorld")
...
[1] "Hello\nWorld"
Try this plugin JQuery UI Message box. He uses jQuery UI Dialog.
You can use the following code to get last day of the month
public static String getLastDayOfTheMonth(String date) {
String lastDayOfTheMonth = "";
SimpleDateFormat formatter = new SimpleDateFormat("dd-MM-yyyy");
try{
java.util.Date dt= formatter.parse(date);
Calendar calendar = Calendar.getInstance();
calendar.setTime(dt);
calendar.add(Calendar.MONTH, 1);
calendar.set(Calendar.DAY_OF_MONTH, 1);
calendar.add(Calendar.DATE, -1);
java.util.Date lastDay = calendar.getTime();
lastDayOfTheMonth = formatter.format(lastDay);
} catch (ParseException e) {
e.printStackTrace();
}
return lastDayOfTheMonth;
}
An abstract class can be used instead of an interface (in C# 7.3).
// Like interface
abstract class IIO
{
public virtual async Task<string> DoOperation(string Name)
{
throw new NotImplementedException(); // throwing exception
// return await Task.Run(() => { return ""; }); // or empty do
}
}
// Implementation
class IOImplementation : IIO
{
public override async Task<string> DoOperation(string Name)
{
return await await Task.Run(() =>
{
if(Name == "Spiderman")
return "ok";
return "cancel";
});
}
}

TypeScript is a typed superset of JavaScript that compiles to plain JavaScript - typescriptlang.org.
JavaScript is a programming language that is developed by EMCA's Technical Committee 39, which is a group of people composed of many different stakeholders. TC39 is a committee hosted by ECMA: an internal standards organization. JavaScript has many different implementations by many different vendors (e.g. Google, Microsoft, Oracle, etc.). The goal of JavaScript is to be the lingua franca of the web.
TypeScript is a superset of the JavaScript language that has a single open-source compiler and is developed mainly by a single vendor: Microsoft. The goal of TypeScript is to help catch mistakes early through a type system and to make JavaScript development more efficient.
Essentially TypeScript achieves its goals in three ways:
Support for modern JavaScript features - The JavaScript language (not the runtime) is standardized through the ECMAScript standards. Not all browsers and JavaScript runtimes support all features of all ECMAScript standards (see this overview). TypeScript allows for the use of many of the latest ECMAScript features and translates them to older ECMAScript targets of your choosing (see the list of compile targets under the --target
compiler option). This means that you can safely use new features, like modules, lambda functions, classes, the spread operator and destructuring, while remaining backwards compatible with older browsers and JavaScript runtimes.
Advanced type system - The type support is not part of the ECMAScript standard and will likely never be due to the interpreted nature instead of compiled nature of JavaScript. The type system of TypeScript is incredibly rich and includes: interfaces, enums, hybrid types, generics, union/intersection types, access modifiers and much more. The official website of TypeScript gives an overview of these features. Typescript's type system is on-par with most other typed languages and in some cases arguably more powerful.
Developer tooling support - TypeScript's compiler can run as a background process to support both incremental compilation and IDE integration such that you can more easily navigate, identify problems, inspect possibilities and refactor your codebase.
TypeScript has a unique philosophy compared to other languages that compile to JavaScript. JavaScript code is valid TypeScript code; TypeScript is a superset of JavaScript. You can almost rename your .js
files to .ts
files and start using TypeScript (see "JavaScript interoperability" below). TypeScript files are compiled to readable JavaScript, so that migration back is possible and understanding the compiled TypeScript is not hard at all. TypeScript builds on the successes of JavaScript while improving on its weaknesses.
On the one hand, you have future proof tools that take modern ECMAScript standards and compile it down to older JavaScript versions with Babel being the most popular one. On the other hand, you have languages that may totally differ from JavaScript which target JavaScript, like CoffeeScript, Clojure, Dart, Elm, Haxe, Scala.js, and a whole host more (see this list). These languages, though they might be better than where JavaScript's future might ever lead, run a greater risk of not finding enough adoption for their futures to be guaranteed. You might also have more trouble finding experienced developers for some of these languages, though the ones you will find can often be more enthusiastic. Interop with JavaScript can also be a bit more involved, since they are farther removed from what JavaScript actually is.
TypeScript sits in between these two extremes, thus balancing the risk. TypeScript is not a risky choice by any standard. It takes very little effort to get used to if you are familiar with JavaScript, since it is not a completely different language, has excellent JavaScript interoperability support and it has seen a lot of adoption recently.
JavaScript is dynamically typed. This means JavaScript does not know what type a variable is until it is actually instantiated at run-time. This also means that it may be too late. TypeScript adds type support to JavaScript and catches type errors during compilation to JavaScript. Bugs that are caused by false assumptions of some variable being of a certain type can be completely eradicated if you play your cards right (how strict you type your code or if you type your code at all is up to you).
TypeScript makes typing a bit easier and a lot less explicit by the usage of type inference. For example: var x = "hello"
in TypeScript is the same as var x : string = "hello"
. The type is simply inferred from its use. Even it you don't explicitly type the types, they are still there to save you from doing something which otherwise would result in a run-time error.
TypeScript is optionally typed by default. For example function divideByTwo(x) { return x / 2 }
is a valid function in TypeScript which can be called with any kind of parameter, even though calling it with a string will obviously result in a runtime error. Just like you are used to in JavaScript. This works, because when no type was explicitly assigned and the type could not be inferred, like in the divideByTwo example, TypeScript will implicitly assign the type any
. This means the divideByTwo function's type signature automatically becomes function divideByTwo(x : any) : any
. There is a compiler flag to disallow this behavior: --noImplicitAny
. Enabling this flag gives you a greater degree of safety, but also means you will have to do more typing.
Types have a cost associated with them. First of all, there is a learning curve, and second of all, of course, it will cost you a bit more time to set up a codebase using proper strict typing too. In my experience, these costs are totally worth it on any serious codebase you are sharing with others. A Large Scale Study of Programming Languages and Code Quality in Github suggests that "statically typed languages, in general, are less defect prone than the dynamic types, and that strong typing is better than weak typing in the same regard".
It is interesting to note that this very same paper finds that TypeScript is less error-prone than JavaScript:
For those with positive coefficients we can expect that the language is associated with, ceteris paribus, a greater number of defect fixes. These languages include C, C++, JavaScript, Objective-C, Php, and Python. The languages Clojure, Haskell, Ruby, Scala, and TypeScript, all have negative coefficients implying that these languages are less likely than the average to result in defect fixing commits.
The development experience with TypeScript is a great improvement over JavaScript. The IDE is informed in real-time by the TypeScript compiler on its rich type information. This gives a couple of major advantages. For example, with TypeScript, you can safely do refactorings like renames across your entire codebase. Through code completion, you can get inline help on whatever functions a library might offer. No more need to remember them or look them up in online references. Compilation errors are reported directly in the IDE with a red squiggly line while you are busy coding. All in all, this allows for a significant gain in productivity compared to working with JavaScript. One can spend more time coding and less time debugging.
There is a wide range of IDEs that have excellent support for TypeScript, like Visual Studio Code, WebStorm, Atom and Sublime.
Runtime errors of the form cannot read property 'x' of undefined
or undefined is not a function
are very commonly caused by bugs in JavaScript code. Out of the box TypeScript already reduces the probability of these kinds of errors occurring, since one cannot use a variable that is not known to the TypeScript compiler (with the exception of properties of any
typed variables). It is still possible though to mistakenly utilize a variable that is set to undefined
. However, with the 2.0 version of TypeScript you can eliminate these kinds of errors all together through the usage of non-nullable types. This works as follows:
With strict null checks enabled (--strictNullChecks
compiler flag) the TypeScript compiler will not allow undefined
to be assigned to a variable unless you explicitly declare it to be of nullable type. For example, let x : number = undefined
will result in a compile error. This fits perfectly with type theory since undefined
is not a number. One can define x
to be a sum type of number
and undefined
to correct this: let x : number | undefined = undefined
.
Once a type is known to be nullable, meaning it is of a type that can also be of the value null
or undefined
, the TypeScript compiler can determine through control flow based type analysis whether or not your code can safely use a variable or not. In other words when you check a variable is undefined
through for example an if
statement the TypeScript compiler will infer that the type in that branch of your code's control flow is not anymore nullable and therefore can safely be used. Here is a simple example:
let x: number | undefined;
if (x !== undefined) x += 1; // this line will compile, because x is checked.
x += 1; // this line will fail compilation, because x might be undefined.
During the build, 2016 conference co-designer of TypeScript Anders Hejlsberg gave a detailed explanation and demonstration of this feature: video (from 44:30 to 56:30).
To use TypeScript you need a build process to compile to JavaScript code. The build process generally takes only a couple of seconds depending of course on the size of your project. The TypeScript compiler supports incremental compilation (--watch
compiler flag) so that all subsequent changes can be compiled at greater speed.
The TypeScript compiler can inline source map information in the generated .js files or create separate .map files. Source map information can be used by debugging utilities like the Chrome DevTools and other IDE's to relate the lines in the JavaScript to the ones that generated them in the TypeScript. This makes it possible for you to set breakpoints and inspect variables during runtime directly on your TypeScript code. Source map information works pretty well, it was around long before TypeScript, but debugging TypeScript is generally not as great as when using JavaScript directly. Take the this
keyword for example. Due to the changed semantics of the this
keyword around closures since ES2015, this
may actually exists during runtime as a variable called _this
(see this answer). This may confuse you during debugging but generally is not a problem if you know about it or inspect the JavaScript code. It should be noted that Babel suffers the exact same kind of issue.
There are a few other tricks the TypeScript compiler can do, like generating intercepting code based on decorators, generating module loading code for different module systems and parsing JSX. However, you will likely require a build tool besides the Typescript compiler. For example, if you want to compress your code you will have to add other tools to your build process to do so.
There are TypeScript compilation plugins available for Webpack, Gulp, Grunt and pretty much any other JavaScript build tool out there. The TypeScript documentation has a section on integrating with build tools covering them all. A linter is also available in case you would like even more build time checking. There are also a great number of seed projects out there that will get you started with TypeScript in combination with a bunch of other technologies like Angular 2, React, Ember, SystemJS, Webpack, Gulp, etc.
Since TypeScript is so closely related to JavaScript it has great interoperability capabilities, but some extra work is required to work with JavaScript libraries in TypeScript. TypeScript definitions are needed so that the TypeScript compiler understands that function calls like _.groupBy
or angular.copy
or $.fadeOut
are not in fact illegal statements. The definitions for these functions are placed in .d.ts
files.
The simplest form a definition can take is to allow an identifier to be used in any way. For example, when using Lodash, a single line definition file declare var _ : any
will allow you to call any function you want on _
, but then, of course, you are also still able to make mistakes: _.foobar()
would be a legal TypeScript call, but is, of course, an illegal call at run-time. If you want proper type support and code completion your definition file needs to to be more exact (see lodash definitions for an example).
Npm modules that come pre-packaged with their own type definitions are automatically understood by the TypeScript compiler (see documentation). For pretty much any other semi-popular JavaScript library that does not include its own definitions somebody out there has already made type definitions available through another npm module. These modules are prefixed with "@types/" and come from a Github repository called DefinitelyTyped.
There is one caveat: the type definitions must match the version of the library you are using at run-time. If they do not, TypeScript might disallow you from calling a function or dereferencing a variable that exists or allow you to call a function or dereference a variable that does not exist, simply because the types do not match the run-time at compile-time. So make sure you load the right version of the type definitions for the right version of the library you are using.
To be honest, there is a slight hassle to this and it may be one of the reasons you do not choose TypeScript, but instead go for something like Babel that does not suffer from having to get type definitions at all. On the other hand, if you know what you are doing you can easily overcome any kind of issues caused by incorrect or missing definition files.
Any .js
file can be renamed to a .ts
file and ran through the TypeScript compiler to get syntactically the same JavaScript code as an output (if it was syntactically correct in the first place). Even when the TypeScript compiler gets compilation errors it will still produce a .js
file. It can even accept .js
files as input with the --allowJs
flag. This allows you to start with TypeScript right away. Unfortunately, compilation errors are likely to occur in the beginning. One does need to remember that these are not show-stopping errors like you may be used to with other compilers.
The compilation errors one gets in the beginning when converting a JavaScript project to a TypeScript project are unavoidable by TypeScript's nature. TypeScript checks all code for validity and thus it needs to know about all functions and variables that are used. Thus type definitions need to be in place for all of them otherwise compilation errors are bound to occur. As mentioned in the chapter above, for pretty much any JavaScript framework there are .d.ts
files that can easily be acquired with the installation of DefinitelyTyped packages. It might, however, be that you've used some obscure library for which no TypeScript definitions are available or that you've polyfilled some JavaScript primitives. In that case, you must supply type definitions for these bits for the compilation errors to disappear. Just create a .d.ts
file and include it in the tsconfig.json's files
array, so that it is always considered by the TypeScript compiler. In it declare those bits that TypeScript does not know about as type any
. Once you've eliminated all errors you can gradually introduce typing to those parts according to your needs.
Some work on (re)configuring your build pipeline will also be needed to get TypeScript into the build pipeline. As mentioned in the chapter on compilation there are plenty of good resources out there and I encourage you to look for seed projects that use the combination of tools you want to be working with.
The biggest hurdle is the learning curve. I encourage you to play around with a small project at first. Look how it works, how it builds, which files it uses, how it is configured, how it functions in your IDE, how it is structured, which tools it uses, etc. Converting a large JavaScript codebase to TypeScript is doable when you know what you are doing. Read this blog for example on converting 600k lines to typescript in 72 hours). Just make sure you have a good grasp of the language before you make the jump.
TypeScript is open-source (Apache 2 licensed, see GitHub) and backed by Microsoft. Anders Hejlsberg, the lead architect of C# is spearheading the project. It's a very active project; the TypeScript team has been releasing a lot of new features in the last few years and a lot of great ones are still planned to come (see the roadmap).
Some facts about adoption and popularity:
As much as this answer might not be the best depending on your use case, it works. Instead of using the Radio button for a Male and Female selection, using the <select> </select>
works perfectly, both for saving and editing.
<select formControlName="gender" name="gender" class="">
<option value="M">Male</option>
<option value="F">Female</option>
</select>
The above should do just fine, for editing using FormGroup with patchValue
. For creating, you could use [(ngModel)]
instead of the formControlName
. Still works.
The plumbing work involved with the radio button one, I chose to go with the select instead. Visually and UX-wise, it doesn't appear to be the best, but from a developer's standpoint, it's a ton easier.
In C99(ISO/IEC 9899:TC3)
which seems absent from this discussion thus far the following steteents are made regarding order of evaluaiton.
[...]the order of evaluation of subexpressions and the order in which side effects take place are both unspecified. (Section 6.5 pp 67)
The order of evaluation of the operands is unspecified. If an attempt is made to modify the result of an assignment operator or to access it after the next sequence point, the behavior[sic] is undefined.(Section 6.5.16 pp 91)
The get
method of a dict (like for example characters
) works just like indexing the dict, except that, if the key is missing, instead of raising a KeyError
it returns the default value (if you call .get
with just one argument, the key, the default value is None
).
So an equivalent Python function (where calling myget(d, k, v)
is just like d.get(k, v)
might be:
def myget(d, k, v=None):
try: return d[k]
except KeyError: return v
The sample code in your question is clearly trying to count the number of occurrences of each character: if it already has a count for a given character, get
returns it (so it's just incremented by one), else get
returns 0 (so the incrementing correctly gives 1
at a character's first occurrence in the string).
UPDATE R
SET R.status = '0'
FROM dbo.ProductReviews AS R
INNER JOIN dbo.products AS P
ON R.pid = P.id
WHERE R.id = '17190'
AND P.shopkeeper = '89137';
I just want to add what solved this problem for me, as it is different to all of the above answers.
The ajax calls that were causing the problem were trying to pass an empty data object. It seems IE does not like this, but other browsers don't mind.
To fix it I simply removed data: {},
from the ajax call.
Switch to the branch from which you created the pull request:
$ git checkout pull-request-branch
Overwrite the modified file(s) with the file in another branch, let's consider it's master:
git checkout origin/master -- src/main/java/HelloWorld.java
Commit and push it to the remote:
git commit -m "Removed a modified file from pull request"
git push origin pull-request-branch
re.search
searches for the pattern throughout the string, whereas re.match
does not search the pattern; if it does not, it has no other choice than to match it at start of the string.
For me it work fine
&:not(:last-child){
text-transform: uppercase;
}
If you are not bothered about the location of the text present, then you could use Driver.PageSource property as below:
Driver.PageSource.Contains("expected message");
I'm not sure how you want to use the file names, but one of these should help:
If you just want to see the names, you can use something like gulp-debug
, which lists the details of the vinyl file. Insert this anywhere you want a list, like so:
var gulp = require('gulp'),
debug = require('gulp-debug');
gulp.task('examples', function() {
return gulp.src('./examples/*.html')
.pipe(debug())
.pipe(gulp.dest('./build'));
});
Another option is gulp-filelog
, which I haven't used, but sounds similar (it might be a bit cleaner).
Another options is gulp-filesize
, which outputs both the file and it's size.
If you want more control, you can use something like gulp-tap
, which lets you provide your own function and look at the files in the pipe.
In general, I always put my enums in a struct
. I have seen several guidelines including "prefixing".
enum Color
{
Clr_Red,
Clr_Yellow,
Clr_Blue,
};
Always thought this looked more like C
guidelines than C++
ones (for one because of the abbreviation and also because of the namespaces in C++
).
So to limit the scope we now have two alternatives:
I personally tend to use a struct
because it can be used as parameters for template programming while a namespace cannot be manipulated.
Examples of manipulation include:
template <class T>
size_t number() { /**/ }
which returns the number of elements of enum inside the struct T
:)
Another way of configuring nvcc to use a specific version of gcc (gcc-4.4, for instance), is to edit nvcc.profile and alter PATH to include the path to the gcc you want to use first.
For example (gcc-4.4.6 installed in /opt):
PATH += /opt/gcc-4.4.6/lib/gcc/x86_64-unknown-linux-gnu/4.4.6:/opt/gcc-4.4.6/bin:$(TOP)/open64/bin:$(TOP)/share/cuda/nvvm:$(_HERE_):
The location of nvcc.profile varies, but it should be in the same directory as the nvcc executable itself.
This is a bit of a hack, as nvcc.profile is not intended for user configuration as per the nvcc manual, but it was the solution which worked best for me.
Not sure if JSF provides a built-in functionality, but you could use java.sql.Date
's constructor to convert to a date object: http://download.oracle.com/javase/1.5.0/docs/api/java/sql/Date.html#Date(long)
Then you should be able to use higher level features provided by Java SE, Java EE to display and format the extracted date. You could instantiate a java.util.Calendar
and explicitly set the time: http://download.oracle.com/javase/1.5.0/docs/api/java/util/Calendar.html#setTime(java.util.Date)
EDIT: The JSF components should not take care of the conversion. Your data access layer (persistence layer) should take care of this. In other words, your JSF components should not handle the long
typed attributes but only a Date
or Calendar
typed attributes.
Git doesn't store file permissions other than executable scripts. Consider using something like git-cache-meta to save file ownership and permissions.
Git can only store two types of modes: 755 (executable) and 644 (not executable). If your file was 444 git would store it has 644.
This accomplishes the same thing but is much simpler:
$(document).ready(function() {
$("#board").delay(1000).append(".");
});
You can chain a delay before almost any jQuery method.
Use the Nlog http://nlog-project.org/. It is free and allows to write to file, database, event log and other 20+ targets. The other logging framework is log4net - http://logging.apache.org/log4net/ (ported from java Log4j project). Its also free.
Best practices are to use common logging - http://commons.apache.org/logging/ So you can later change NLog or log4net to other logging framework.
Recursion is your friend. I updated the function to account for property arrays:
function getObject(theObject) {
var result = null;
if(theObject instanceof Array) {
for(var i = 0; i < theObject.length; i++) {
result = getObject(theObject[i]);
if (result) {
break;
}
}
}
else
{
for(var prop in theObject) {
console.log(prop + ': ' + theObject[prop]);
if(prop == 'id') {
if(theObject[prop] == 1) {
return theObject;
}
}
if(theObject[prop] instanceof Object || theObject[prop] instanceof Array) {
result = getObject(theObject[prop]);
if (result) {
break;
}
}
}
}
return result;
}

I feel a bit stupid on this but let this be a lesson to everyone...Make sure you target the right selector!
Basically the console wasn't logging anything because this particular code snippet was attempting to grab the scrolling area of my window, when in fact my code was setup differently to scroll an entire DIV instead. As soon as I changed:
$(window).scroll(function() {
to this:
$('#scroller').scroll(function() {
The console started logging the correct messages.
I'm going to begin this answer with an illustration:
var colours = ['red', 'green', 'blue'];
document.getElementById('element').addEventListener('click', function() {
// this is a reference to the element clicked on
var that = this;
colours.forEach(function() {
// this is undefined
// that is a reference to the element clicked on
});
});
My answer originally demonstrated this with jQuery, which is only very slightly different:
$('#element').click(function(){
// this is a reference to the element clicked on
var that = this;
$('.elements').each(function(){
// this is a reference to the current element in the loop
// that is still a reference to the element clicked on
});
});
Because this
frequently changes when you change the scope by calling a new function, you can't access the original value by using it. Aliasing it to that
allows you still to access the original value of this
.
Personally, I dislike the use of that
as the alias. It is rarely obvious what it is referring to, especially if the functions are longer than a couple of lines. I always use a more descriptive alias. In my examples above, I'd probably use clickedEl
.
OPT
ional
It holds optional software and packages that you install that are not required for the system to run.
changing java proxy settings to direct connection did not fix my issue.
What worked for me:
This is a way to create tables dynamically using T-SQL stored procedures:
declare @cmd nvarchar(1000), @MyTableName nvarchar(100);
set @MyTableName = 'CustomerDetails';
set @cmd = 'CREATE TABLE dbo.' + quotename(@MyTableName, '[') + '(ColumnName1 int not null,ColumnName2 int not null);';
Execute it as:
exec(@cmd);
In this case a relatively simple GROUP BY
can work, but in general, when there are additional columns where you can't order by but you want them from the particular row which they are associated with, you can either join back to the detail using all the parts of the key or use OVER()
:
Runnable example (Wofkflow20 error in original data corrected)
;WITH partitioned AS (
SELECT company
,workflow
,date
,other_columns
,ROW_NUMBER() OVER(PARTITION BY company, workflow
ORDER BY date) AS seq
FROM workflowTable
)
SELECT *
FROM partitioned WHERE seq = 1
In summary, valid characters in the text are:
&

.>
is not valid if following ]]
.Sections 2.2 and 2.4 of the XML specification provide the answer in detail:
Characters
Legal characters are tab, carriage return, line feed, and the legal characters of Unicode and ISO/IEC 10646
Character data
The ampersand character (&) and the left angle bracket (<) must not appear in their literal form, except when used as markup delimiters, or within a comment, a processing instruction, or a CDATA section. If they are needed elsewhere, they must be escaped using either numeric character references or the strings " & " and " < " respectively. The right angle bracket (>) may be represented using the string " > ", and must, for compatibility, be escaped using either " > " or a character reference when it appears in the string " ]]> " in content, when that string is not marking the end of a CDATA section.
// Remove active for all items.
$('.sidebar-menu li').removeClass('active');
// highlight submenu item
$('li a[href="' + this.location.pathname + '"]').parent().addClass('active');
// Highlight parent menu item.
$('ul a[href="' + this.location.pathname + '"]').parents('li').addClass('active')
Have you tried using the "auto-fill" in Excel?
If you have an entire column of items you put the formula in the first cell, make sure you get the result you desire and then you can do the copy/paste, or use auto fill which is an option that sits on the bottom right corner of the cell.
You go to that corner in the cell and once your cursor changes to a "+", you can double-click on it and it should populate all the way down to the last entry (as long as there are no populated cells, that is).
In general I use system
, open
, IPC::Open2
, or IPC::Open3
depending on what I want to do. The qx//
operator, while simple, is too constraining in its functionality to be very useful outside of quick hacks. I find open
to much handier.
system
: run a command and wait for it to returnUse system
when you want to run a command, don't care about its output, and don't want the Perl script to do anything until the command finishes.
#doesn't spawn a shell, arguments are passed as they are
system("command", "arg1", "arg2", "arg3");
or
#spawns a shell, arguments are interpreted by the shell, use only if you
#want the shell to do globbing (e.g. *.txt) for you or you want to redirect
#output
system("command arg1 arg2 arg3");
qx//
or ``: run a command and capture its STDOUTUse qx//
when you want to run a command, capture what it writes to STDOUT, and don't want the Perl script to do anything until the command finishes.
#arguments are always processed by the shell
#in list context it returns the output as a list of lines
my @lines = qx/command arg1 arg2 arg3/;
#in scalar context it returns the output as one string
my $output = qx/command arg1 arg2 arg3/;
exec
: replace the current process with another process.Use exec
along with fork
when you want to run a command, don't care about its output, and don't want to wait for it to return. system
is really just
sub my_system {
die "could not fork\n" unless defined(my $pid = fork);
return waitpid $pid, 0 if $pid; #parent waits for child
exec @_; #replace child with new process
}
You may also want to read the waitpid
and perlipc
manuals.
open
: run a process and create a pipe to its STDIN or STDERRUse open
when you want to write data to a process's STDIN or read data from a process's STDOUT (but not both at the same time).
#read from a gzip file as if it were a normal file
open my $read_fh, "-|", "gzip", "-d", $filename
or die "could not open $filename: $!";
#write to a gzip compressed file as if were a normal file
open my $write_fh, "|-", "gzip", $filename
or die "could not open $filename: $!";
Use IPC::Open2
when you need to read from and write to a process's STDIN and STDOUT.
use IPC::Open2;
open2 my $out, my $in, "/usr/bin/bc"
or die "could not run bc";
print $in "5+6\n";
my $answer = <$out>;
use IPC::Open3
when you need to capture all three standard file handles of the process. I would write an example, but it works mostly the same way IPC::Open2 does, but with a slightly different order to the arguments and a third file handle.
Here is the another way to achive this:
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
item.setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
item.setEnabled(true);
item.setTitle(Html.fromHtml("<font color='#ff3824'>Settings</font>"));
return false;
}
});
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
Another possible solution:
var MyReader = new System.Configuration.AppSettingsReader();
string keyvalue = MyReader.GetValue("keyalue",typeof(string)).ToString();
mylist = [("aaaa8"),("bb8"),("ccc8"),("dddddd8")]
print mylist
j=0
for i in mylist:
mylist[j]=i.rstrip("8")
j+=1
print mylist
No, but you might consider using a set of functions (or macros) to approximate using default args:
// No default args
int foo3(int a, int b, int c)
{
return ...;
}
// Default 3rd arg
int foo2(int a, int b)
{
return foo3(a, b, 0); // default c
}
// Default 2nd and 3rd args
int foo1(int a)
{
return foo3(a, 1, 0); // default b and c
}
Set your PYTHONPATH environment variable. For example like this PYTHONPATH=.:.. (for *nix family).
Also you can manually add your current directory (src in your case) to pythonpath:
import os
import sys
sys.path.insert(0, os.getcwd())
Get-ChildItem $originalPath\* -Include @("*.gif", "*.jpg", "*.xls*", "*.doc*", "*.pdf*", "*.wav*", "*.ppt")
embedded with closures or functions is one way. This is common in JS although not required for non-browser platforms or browser workers.
In Python it seems a bit strange, but if something really needs to be hidden than that might be the way. More to the point using the python API and keeping things that require to be hidden in the C (or other language) is probably the best way. Failing that I would go for putting the code inside a function, calling that and having it return the items you want to export.
It's worth noting that the distinct
keyword in HQL does not map directly to the distinct
keyword in SQL.
If you use the distinct
keyword in HQL, then sometimes Hibernate will use the distinct
SQL keyword, but in some situations it will use a result transformer to produce distinct results. For example when you are using an outer join like this:
select distinct o from Order o left join fetch o.lineItems
It is not possible to filter out duplicates at the SQL level in this case, so Hibernate uses a ResultTransformer
to filter duplicates after the SQL query has been performed.
As Leo points out, the code you added to your question would not suggest a strong reference cycle (a.k.a., retain cycle). One operation-related issue that could cause a strong reference cycle would be if the operation is not getting released. While your code snippet suggests that you have not defined your operation to be concurrent, but if you have, it wouldn't be released if you never posted isFinished
, or if you had circular dependencies, or something like that. And if the operation isn't released, the view controller wouldn't be released either. I would suggest adding a breakpoint or NSLog
in your operation's dealloc
method and confirm that's getting called.
You said:
I understand the notion of retain cycles, but I am not quite sure what happens in blocks, so that confuses me a little bit
The retain cycle (strong reference cycle) issues that occur with blocks are just like the retain cycle issues you're familiar with. A block will maintain strong references to any objects that appear within the block, and it will not release those strong references until the block itself is released. Thus, if block references self
, or even just references an instance variable of self
, that will maintain strong reference to self, that is not resolved until the block is released (or in this case, until the NSOperation
subclass is released.
For more information, see the Avoid Strong Reference Cycles when Capturing self section of the Programming with Objective-C: Working with Blocks document.
If your view controller is still not getting released, you simply have to identify where the unresolved strong reference resides (assuming you confirmed the NSOperation
is getting deallocated). A common example is the use of a repeating NSTimer
. Or some custom delegate
or other object that is erroneously maintaining a strong
reference. You can often use Instruments to track down where objects are getting their strong references, e.g.:
Or in Xcode 5:
First of all go to the /home directorty then open invisible shell script with some text editor, ~/.bash_profile (macOS) or ~/.bashrc (linux)
go to the bottom, you would see something like this,
export LD_LIBRARY_PATH = /usr/local/lib
change this like that( remove blank point around the =
),
export LD_LIBRARY_PATH=/usr/local/lib
it should be useful.

Eclipse Juno, Indigo and Kepler when using the bundled maven version(m2e), are not suppressing the message SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". This behaviour is present from the m2e version 1.1.0.20120530-0009 and onwards.
Although, this is indicated as an error your logs will be saved normally. The highlighted error will still be present until there is a fix of this bug. More about this in the m2e support site.
The current available solution is to use an external maven version rather than the bundled version of Eclipse. You can find about this solution and more details regarding this bug in the question below which i believe describes the same problem you are facing.
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". error
Separate the time value from the date value if you want to use indexes in your search (you probably should, for performance). You can: (1) use function-based indexes or (2) create a new column for time only, index this column and use it in you SELECT
clause.
Keep in mind you will lose any index performance boost if you use functions in a SQL's WHERE
clause, the engine has to do a scan search. Just run your query with EXPLAIN SELECT...
to confirm this. This happens because the engine has to process EVERY value in the field for EACH comparison, and the converted value is not indexed.
Most answers say to use float()
, convert()
, cast()
, addtime()
, etc.. Again, your database won't use indexes if you do this. For small tables that may be OK.
It is OK to use functions in WHERE
params though (where field = func(value)
), because you won't be changing EACH field's value in the table.
In case you want to keep use of indexes, you can create a function-based index for the time value. The proper way to do this (and support for it) may depend on your database engine. Another option is adding a column to store only the time value and index this column, but try the former approach first.
Do some performance tests before updating your database to have a new time column or whatever to make use of indexes. In my tests, I found out the performance boost was minimal (when I could see some improvement) and wouldn't be worth the trouble and overhead of adding a new index.
In relation to the original question I'd like to add to the accepted answer by Mohamed Mansour that there is also a way to make this work the other way around:
You can access other extension pages (i.e. options page, popup page) from within the background page/script with the chrome.extension.getViews()
call. As described here.
// overwrite the console object with the right one.
var optionsPage = ( chrome.extension.getViews()
&& (chrome.extension.getViews().length > 1) )
? chrome.extension.getViews()[1] : null;
// safety precaution.
if (optionsPage) {
var console = optionsPage.console;
}
Are you sure you are using Python 3.x? The syntax isn't available in Python 2.x because print
is still a statement.
print("foo" % bar, end=" ")
in Python 2.x is identical to
print ("foo" % bar, end=" ")
or
print "foo" % bar, end=" "
i.e. as a call to print with a tuple as argument.
That's obviously bad syntax (literals don't take keyword arguments). In Python 3.x print
is an actual function, so it takes keyword arguments, too.
The correct idiom in Python 2.x for end=" "
is:
print "foo" % bar,
(note the final comma, this makes it end the line with a space rather than a linebreak)
If you want more control over the output, consider using sys.stdout
directly. This won't do any special magic with the output.
Of course in somewhat recent versions of Python 2.x (2.5 should have it, not sure about 2.4), you can use the __future__
module to enable it in your script file:
from __future__ import print_function
The same goes with unicode_literals
and some other nice things (with_statement
, for example). This won't work in really old versions (i.e. created before the feature was introduced) of Python 2.x, though.
Better yet, consider sp_getapplock
which is designed for this. Or use SET LOCK_TIMEOUT
Otherwise, you'd have to do something with sys.dm_tran_locks
which I'd use only for DBA stuff: not for user defined concurrency.
Nested ifs:
if (condition)
{
// half-massive amount of code here
if (!breakOutCondition)
{
//half-massive amount of code here
}
}
At the risk of being downvoted -- it's happened to me in the past -- I'll mention that another (unpopular) option would of course be the dreaded goto
; a break statement is just a goto in disguise.
And finally, I'll echo the common sentiment that your design could probably be improved so that the massive if statement is not necessary, let alone breaking out of it. At least you should be able to extract a couple of methods, and use a return:
if (condition)
{
ExtractedMethod1();
if (breakOutCondition)
return;
ExtractedMethod2();
}
There is no way to recursively search through the classpath. You need to know the Full pathname of a resource to be able to retrieve it in this way. The resource may be in a directory in the file system or in a jar file so it is not as simple as performing a directory listing of "the classpath". You will need to provide the full path of the resource e.g. '/com/mypath/bla.xml'.
For your second question, getResource will return the first resource that matches the given resource name. The order that the class path is searched is given in the javadoc for getResource.
I think these official guide should work for your case.
VS Code allows you to quickly search over all files in the currently-opened folder. Press Ctrl+Shift+F and enter in your search term. Search results are grouped into files containing the search term, with an indication of the hits in each file and its location. Expand a file to see a preview of all of the hits within that file. Then single-click on one of the hits to view it in the editor.
One notice. On Windows, place your _curlrc in '%APPDATA%' or '%USERPROFILE%\Application Data'.
I had this issue recently and I resolved it by simply rolling IE8 back to IE7.
My guess is that IE7 had these files as a wrapper for working on Windows XP, but IE8 was likely made to work with Vista/7 so it removed the files because the later editions just don't use the shim.
This should work for you:
IF NOT EXIST "\path\to\your\folder" md \path\to\your\folder
However, there is another method, but it may not be 100% useful:
md \path\to\your\folder >NUL 2>NUL
This one creates the folder, but does not show the error output if folder exists. I highly recommend that you use the first one. The second one is if you have problems with the other.
Check to make sure that both score and array[x] are numerical types. You might be comparing an integer to a string...which is heartbreakingly possible in Python 2.x.
>>> 2 < "2"
True
>>> 2 > "2"
False
>>> 2 == "2"
False
Edit
Further explanation: How does Python compare string and int?
Context.getResources().getDimension(int id);
Set the image to be the background of a div, then set the background size to be half the width of the image.
<div class="myimage"></div>
Then in your css, if your image is 300px x 200px:
.myimage {
background: url('images/myimage.png') no-repeat;
background-size:150px;
width:150px;
height:100px;
}
If the object is actually a Boolean
instance, then just cast it:
boolean di = (Boolean) someObject;
The explicit cast will do the conversion to Boolean
, and then there's the auto-unboxing to the primitive value. Or you can do that explicitly:
boolean di = ((Boolean) someObject).booleanValue();
If someObject
doesn't refer to a Boolean value though, what do you want the code to do?
I found this will have git ignore temporary files created by vim:
[._]*.s[a-w][a-z]
[._]s[a-w][a-z]
*.un~
Session.vim
.netrwhist
*~
It can also be viewed here.
call/apply executes function immediately:
func.call(context, arguments);
func.apply(context, [argument1,argument2,..]);
bind doesn't execute function immediately, but returns wrapped apply function (for later execution):
function bind(func, context) {
return function() {
return func.apply(context, arguments);
};
}
You can add property to your model as follows:
public string DetailsClass { get { return Details.Count > 0 ? "show" : "hide" } }
and then your view will be simpler and will contain no logic at all:
<div class="details @Model.DetailsClass"/>
This will work even with many classes and will not render class if it is null:
<div class="@Model.Class1 @Model.Class2"/>
with 2 not null properties will render:
<div class="class1 class2"/>
if class1 is null
<div class=" class2"/>
I thought I would expand on these answers for OSX and Linux folks (not that they need it):
I prefer to use mvnDebug too. But after OSX maverick destroyed my Java dev environment, I am starting from scratch and stubbled upon this post, and thought I would add to it.
$ mvnDebug vertx:runMod
-bash: mvnDebug: command not found
DOH! I have not set it up on this box after the new SSD drive and/or the reset of everything Java when I installed Maverick.
I use a package manager for OSX and Linux so I have no idea where mvn really lives. (I know for brief periods of time.. thanks brew.. I like that I don't know this.)
Let's see:
$ which mvn
/usr/local/bin/mvn
There you are... you little b@stard.
Now where did you get installed to:
$ ls -l /usr/local/bin/mvn
lrwxr-xr-x 1 root wheel 39 Oct 31 13:00 /
/usr/local/bin/mvn -> /usr/local/Cellar/maven30/3.0.5/bin/mvn
Aha! So you got installed in /usr/local/Cellar/maven30/3.0.5/bin/mvn. You cheeky little build tool. No doubt by homebrew...
Do you have your little buddy mvnDebug with you?
$ ls /usr/local/Cellar/maven30/3.0.5/bin/mvnDebug
/usr/local/Cellar/maven30/3.0.5/bin/mvnDebug
Good. Good. Very good. All going as planned.
Now move that little b@stard where I can remember him more easily.
$ ln -s /usr/local/Cellar/maven30/3.0.5/bin/mvnDebug /usr/local/bin/mvnDebug
ln: /usr/local/bin/mvnDebug: Permission denied
Darn you computer... You will submit to my will. Do you know who I am? I am SUDO! BOW!
$ sudo ln -s /usr/local/Cellar/maven30/3.0.5/bin/mvnDebug /usr/local/bin/mvnDebug
Now I can use it from Eclipse (but why would I do that when I have IntelliJ!!!!)
$ mvnDebug vertx:runMod
Preparing to Execute Maven in Debug Mode
Listening for transport dt_socket at address: 8000
Internally mvnDebug uses this:
MAVEN_DEBUG_OPTS="-Xdebug -Xnoagent -Djava.compiler=NONE \
-Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=8000"
So you could modify it (I usually debug on port 9090).
This blog explains how to setup Eclipse remote debugging (shudder)
http://javarevisited.blogspot.com/2011/02/how-to-setup-remote-debugging-in.html
Ditto Netbeans
https://blogs.oracle.com/atishay/entry/use_netbeans_to_debug_a
Ditto IntelliJ http://www.jetbrains.com/idea/webhelp/run-debug-configuration-remote.html
Here is some good docs on the -Xdebug command in general.
http://docs.oracle.com/cd/E13150_01/jrockit_jvm/jrockit/jrdocs/refman/optionX.html
"-Xdebug enables debugging capabilities in the JVM which are used by the Java Virtual Machine Tools Interface (JVMTI). JVMTI is a low-level debugging interface used by debuggers and profiling tools. With it, you can inspect the state and control the execution of applications running in the JVM."
"The subset of JVMTI that is most typically used by profilers is always available. However, the functionality used by debuggers to be able to step through the code and set breakpoints has some overhead associated with it and is not always available. To enable this functionality you must use the -Xdebug option."
-Xrunjdwp:transport=dt_socket,server=y,suspend=n myApp
Check out the docs on -Xrunjdwp too. You can enable it only when a certain exception is thrown for example. You can start it up suspended or running. Anyway.. I digress.
You can use a try-except
try:
print(str.to.id)
except AttributeError: # Not a Retweet
print('null')
Comparision:
if (userProfile.AccountType == AccountType.Retailer)
{
//your code
}
In case to prevent the NullPointerException you could add the following condition before comparing the AccountType:
if(userProfile != null)
{
if (userProfile.AccountType == AccountType.Retailer)
{
//your code
}
}
or shorter version:
if (userProfile !=null && userProfile.AccountType == AccountType.Retailer)
{
//your code
}
You could try csync, it is the sync engine under the hood of owncloud.

In newer versions of OS X (especially Yosemite, EL Capitan), Apple has removed Java support for security reasons. To fix this you have to do the following.
Mount the disk image file and install Java 6 runtime for OS X.
After this you should not be seeing any of the below messages:
- Unable to find any JVMs matching version "(null)"
- No Java runtime present, try --request to install.
b = email.message_from_string(a)

The .NET documentation says: State Property: A bitwise combination of the ConnectionState values
So I think you should check
!myConnection.State.HasFlag(ConnectionState.Open)
instead of
myConnection.State != ConnectionState.Open
because State can have multiple flags.
I think, this could be done without IIS URL Rewrite module. <httpRedirect>
supports wildcards, so you can configure it this way:
<system.webServer>
<httpRedirect enabled="true">
<add wildcard="/" destination="/menu_1/MainScreen.aspx" />
</httpRedirect>
</system.webServer>
Note that you need to have the "HTTP Redirection" feature enabled on IIS - see HTTP Redirects

Everybody is using the parse_url
function, but sometimes user may pass the argumet in different format.
So as to fix that, I have created the function. Check this out:
function fixDomainName($url='')
{
$strToLower = strtolower(trim($url));
$httpPregReplace = preg_replace('/^http:\/\//i', '', $strToLower);
$httpsPregReplace = preg_replace('/^https:\/\//i', '', $httpPregReplace);
$wwwPregReplace = preg_replace('/^www\./i', '', $httpsPregReplace);
$explodeToArray = explode('/', $wwwPregReplace);
$finalDomainName = trim($explodeToArray[0]);
return $finalDomainName;
}
Just pass the URL and get the domain.
For example,
echo fixDomainName('https://stackoverflow.com');
will return the result will be
stackoverflow.com
And in some situation:
echo fixDomainName('stackoverflow.com/questions/id/slug');
And it will also return stackoverflow.com
.
You can also use MetaWhere gem to not mix up your code with SQL stuff:
Person.where((:name => "John") | (:lastname => "Smith"))
The following should work, but you may need to change the format:
echo date('l F jS, Y (m-d-Y)', strtotime('+3 months', strtotime($DateToAdjust)));
Using parameter --force:
npm i -f
For Antlr 4 the java code generation process is below:-

Update your jar name in classpath accordingly.
Have you tried it with the same() matcher? As in:
verify(mockObj).someMethod(same(specificInstance));
I had the same problem. I tried it with the eq() matcher as well as the refEq() matcher but I always had false positives. When I used the same() matcher, the test failed when the arguments were different instances and passed once the arguments were the same instance.
var foo = true;
if (foo){
window.location.reload(true);
foo = false;
}
I was able to figure it out. In case someone wants to know below the code that worked for me:
ASCIIEncoding ascii = new ASCIIEncoding();
byte[] byteArray = Encoding.UTF8.GetBytes(sOriginal);
byte[] asciiArray = Encoding.Convert(Encoding.UTF8, Encoding.ASCII, byteArray);
string finalString = ascii.GetString(asciiArray);
Let me know if there is a simpler way o doing it.
When you use a code like this:
using (var rsa = new RSACryptoServiceProvider(1024))
{
// Do something with the key...
// Encrypt, export, etc.
}
.NET (actually Windows) stores your key in a persistent key container forever. The container is randomly generated by .NET
This means:
Any random RSA/DSA key you have EVER generated for the purpose of protecting data, creating custom X.509 certificate, etc. may have been exposed without your awareness in the Windows file system. Accessible by anyone who has access to your account.
Your disk is being slowly filled with data. Normally not a big concern but it depends on your application (e.g. it might generates hundreds of keys every minute).
To resolve these issues:
using (var rsa = new RSACryptoServiceProvider(1024))
{
try
{
// Do something with the key...
// Encrypt, export, etc.
}
finally
{
rsa.PersistKeyInCsp = false;
}
}

Bearer token is one or more repetition of alphabet, digit, "-" , "." , "_" , "~" , "+" , "/" followed by 0 or more "=".
RFC 6750 2.1. Authorization Request Header Field (Format is ABNF (Augmented BNF))
The syntax for Bearer credentials is as follows:
b64token = 1*( ALPHA / DIGIT /
"-" / "." / "_" / "~" / "+" / "/" ) *"="
credentials = "Bearer" 1*SP b64token
It looks like Base64 but according to Should the token in the header be base64 encoded?, it is not.
Digging a bit deeper in to "HTTP/1.1, part 7: Authentication"**, however, I see that b64token is just an ABNF syntax definition allowing for characters typically used in base64, base64url, etc.. So the b64token doesn't define any encoding or decoding but rather just defines what characters can be used in the part of the Authorization header that will contain the access token.
This fully addresses the first 3 items in the OP question's list. So I'm extending this answer to address the 4th question, about whether the token must be validated, so @mon feel free to remove or edit:
The authorizer is responsible for accepting or rejecting the http request. If the authorizer says the token is valid, it's up to you to decide what this means:

To install Pycrypto in Windows,
Try this in Command Prompt,
Set path=C:\Python27\Scripts (i.e path where easy_install is located)
Then execute the following,
easy_install pycrypto
For Ubuntu:
Try this,
Download Pycrypto from "https://pypi.python.org/pypi/pycrypto"
Then change your current path to downloaded path using your terminal and user should be root:
Eg: root@xyz-virtual-machine:~/pycrypto-2.6.1#
Then execute the following using the terminal:
python setup.py install
It's worked for me. Hope works for all..
You have two options as far as I know:
SaveChanges()
.If you use option 2, you're losing some of the abstraction that the Entity Framework gives you, but if you need to perform a very large update, this might be the best choice for performance reasons.
It works for me just run following command
git config --global http.sslVerify false
it will open a git credentials window give your credentials . for first time only it ask
SELECT a AS current_a, COUNT(*) AS b,
(SELECT COUNT(*) FROM t WHERE a = current_a AND c = 'const' ) as d
from t group by a order by b desc
You are the 742342nd user to ask this bash FAQ. The answer also describes the general case of variables set in subshells created by pipes:
E4) If I pipe the output of a command into
read variable
, why doesn't the output show up in$variable
when the read command finishes?This has to do with the parent-child relationship between Unix processes. It affects all commands run in pipelines, not just simple calls to
read
. For example, piping a command's output into awhile
loop that repeatedly callsread
will result in the same behavior.Each element of a pipeline, even a builtin or shell function, runs in a separate process, a child of the shell running the pipeline. A subprocess cannot affect its parent's environment. When the
read
command sets the variable to the input, that variable is set only in the subshell, not the parent shell. When the subshell exits, the value of the variable is lost.Many pipelines that end with
read variable
can be converted into command substitutions, which will capture the output of a specified command. The output can then be assigned to a variable:grep ^gnu /usr/lib/news/active | wc -l | read ngroup
can be converted into
ngroup=$(grep ^gnu /usr/lib/news/active | wc -l)
This does not, unfortunately, work to split the text among multiple variables, as read does when given multiple variable arguments. If you need to do this, you can either use the command substitution above to read the output into a variable and chop up the variable using the bash pattern removal expansion operators or use some variant of the following approach.
Say /usr/local/bin/ipaddr is the following shell script:
#! /bin/sh host `hostname` | awk '/address/ {print $NF}'
Instead of using
/usr/local/bin/ipaddr | read A B C D
to break the local machine's IP address into separate octets, use
OIFS="$IFS" IFS=. set -- $(/usr/local/bin/ipaddr) IFS="$OIFS" A="$1" B="$2" C="$3" D="$4"
Beware, however, that this will change the shell's positional parameters. If you need them, you should save them before doing this.
This is the general approach -- in most cases you will not need to set $IFS to a different value.
Some other user-supplied alternatives include:
read A B C D << HERE $(IFS=.; echo $(/usr/local/bin/ipaddr)) HERE
and, where process substitution is available,
read A B C D < <(IFS=.; echo $(/usr/local/bin/ipaddr))

I'll answer for horizontal stretching of text, since the vertical is the easy part - just use "transform: scaleY()"
.stretched-text {
letter-spacing: 2px;
display: inline-block;
font-size: 32px;
transform: scaleY(0.5);
transform-origin: 0 0;
margin-bottom: -50%;
}
span {
font-size: 16px;
vertical-align: top;
}
_x000D_
<span class="stretched-text">this is some stretched text</span>
<span>and this is some random<br />triple line <br />not stretched text</span>
_x000D_
letter-spacing just adds space between letters, stretches nothing, but it's kinda relative
inline-block because inline elements are too restrictive and the code below wouldn't work otherwise
font-size to get to the size we want - that way the text will really be of the length it's supposed to be and the text before and after it will appear next to it (scaleX is just for show, the browser still sees the element at its original size when positioning other elements).
scaleY to reduce the height of the text, so that it's the same as the text beside it.
transform-origin to make the text scale from the top of the line.
margin-bottom set to a negative value, so that the next line will not be far below - preferably percentage, so that we won't change the line-height property. vertical-align set to top, to prevent the text before or after from floating to other heights (since the stretched text has a real size of 32px)
-- The simple span element has a font-size, only as a reference.
The question asked for a way to prevent the boldness of the text caused by the stretch and I still haven't given one, BUT the font-weight property has more values than just normal and bold.
I know, you just can't see that, but if you search for the appropriate fonts, you can use the more values.

FWIW, I had this same error message under JSch 0.1.50. Upgrading to 0.1.52 solved the problem.
I had the same problem earlier when I tried to edit an open source project from the internet .
Solved it by just Cleaning the solution and rebuilding it .
Hope this helps.
One option is to use lapply
and class
. For example:
> foo <- data.frame(c("a", "b"), c(1, 2))
> names(foo) <- c("SomeFactor", "SomeNumeric")
> lapply(foo, class)
$SomeFactor
[1] "factor"
$SomeNumeric
[1] "numeric"
Another option is str
:
> str(foo)
'data.frame': 2 obs. of 2 variables:
$ SomeFactor : Factor w/ 2 levels "a","b": 1 2
$ SomeNumeric: num 1 2
SELECT @var = col1,
@var2 = col2
FROM Table
Here is some interesting information about SET / SELECT
- SET is the ANSI standard for variable assignment, SELECT is not.
- SET can only assign one variable at a time, SELECT can make multiple assignments at once.
- If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one)
- When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value)
- As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.
Move all of your state and your handleClick
function from Header
to your MainWrapper
component.
Then pass values as props to all components that need to share this functionality.
class MainWrapper extends React.Component {
constructor() {
super();
this.state = {
sidbarPushCollapsed: false,
profileCollapsed: false
};
this.handleClick = this.handleClick.bind(this);
}
handleClick() {
this.setState({
sidbarPushCollapsed: !this.state.sidbarPushCollapsed,
profileCollapsed: !this.state.profileCollapsed
});
}
render() {
return (
//...
<Header
handleClick={this.handleClick}
sidbarPushCollapsed={this.state.sidbarPushCollapsed}
profileCollapsed={this.state.profileCollapsed} />
);
Then in your Header's render() method, you'd use this.props
:
<button type="button" id="sidbarPush" onClick={this.props.handleClick} profile={this.props.profileCollapsed}>
I suspect that this occurs after an attempt to undeploy your app. Do you ever kill off that thread that you've initialised during the init()
process ? I would do this in the corresponding destroy()
method.
You have a few options:
1) Use the Bundle from the Intent:
Intent mIntent = new Intent(this, Example.class);
Bundle extras = mIntent.getExtras();
extras.putString(key, value);
2) Create a new Bundle
Intent mIntent = new Intent(this, Example.class);
Bundle mBundle = new Bundle();
mBundle.putString(key, value);
mIntent.putExtras(mBundle);
3) Use the putExtra() shortcut method of the Intent
Intent mIntent = new Intent(this, Example.class);
mIntent.putExtra(key, value);
Then, in the launched Activity, you would read them via:
String value = getIntent().getExtras().getString(key)
NOTE: Bundles have "get" and "put" methods for all the primitive types, Parcelables, and Serializables. I just used Strings for demonstrational purposes.
Going to keep this pithier, this is already asked and answered above .
I'd step back however and answer it slightly differently, the docker engine itself adds orchestration as one of its extras and this is the disruptive part. Once you start running an app as a combination of containers running 'somewhere' across multiple container engines it gets really exciting. Robustness, Horizontal Scaling, complete abstraction from the underlying hardware, i could go on and on...
Its not just Docker that gives you this, in fact the de facto Container Orchestration standard is Kubernetes which comes in a lot of flavours, a Docker one, but also OpenShift, SuSe, Azure, AWS...
Then beneath K8S there are alternative container engines; the interesting ones are Docker and CRIO - recently built, daemonless, intended as a container engine specifically for Kubernetes but immature. Its the competition between these that I think will be the real long term choice for a container engine.
There are two main differences.
The first one is related to how you will access the relationship. For a unidirectional association, you can navigate the association from one end only.
So, for a unidirectional @ManyToOne
association, it means you can only access the relationship from the child side where the foreign key resides.
If you have a unidirectional @OneToMany
association, it means you can only access the relationship from the parent side which manages the foreign key.
For the bidirectional @OneToMany
association, you can navigate the association in both ways, either from the parent or from the child side.
You also need to use add/remove utility methods for bidirectional associations to make sure that both sides are properly synchronized.
The second aspect is related to performance.
@OneToMany
, unidirectional associations don't perform as well as bidirectional ones.@OneToOne
, a bidirectional association will cause the parent to be fetched eagerly if Hibernate cannot tell whether the Proxy should be assigned or a null value.@ManyToMany
, the collection type makes quite a difference as Sets
perform better than Lists
.Give the height and width you need for your image to the div that contains the <img> tag. Don't forget to give the height/width in the proper style tag.
In the <img> tag, give the max-height
and max-width
as 100%.
<div style="height:750px; width:700px;">
<img alt="That Image" style="max-height:100%; max-width:100%;" src="">
</div>
You can add the details in the appropriate classes after you get it right.

here is the Guid version they have in case the link does not work later.
module System {
export class Guid {
constructor (public guid: string) {
this._guid = guid;
}
private _guid: string;
public ToString(): string {
return this.guid;
}
// Static member
static MakeNew(): Guid {
var result: string;
var i: string;
var j: number;
result = "";
for (j = 0; j < 32; j++) {
if (j == 8 || j == 12 || j == 16 || j == 20)
result = result + '-';
i = Math.floor(Math.random() * 16).toString(16).toUpperCase();
result = result + i;
}
return new Guid(result);
}
}
}
You can dump the value in hex using UTL_RAW.CAST_TO_RAW(UTL_RAW.CAST_TO_VARCHAR2())
.
SELECT b FROM foo;
-- (BLOB)
SELECT UTL_RAW.CAST_TO_RAW(UTL_RAW.CAST_TO_VARCHAR2(b))
FROM foo;
-- 1F8B080087CDC1520003F348CDC9C9D75128CF2FCA49D1E30200D7BBCDFC0E000000
This is handy because you this is the same format used for inserting into BLOB columns:
CREATE GLOBAL TEMPORARY TABLE foo (
b BLOB);
INSERT INTO foo VALUES ('1f8b080087cdc1520003f348cdc9c9d75128cf2fca49d1e30200d7bbcdfc0e000000');
DESC foo;
-- Name Null Type
-- ---- ---- ----
-- B BLOB
However, at a certain point (2000 bytes?) the corresponding hex string exceeds Oracle’s maximum string length. If you need to handle that case, you’ll have to combine How do I get textual contents from BLOB in Oracle SQL with the documentation for DMBS_LOB.SUBSTR
for a more complicated approach that will allow you to see substrings of the BLOB.

If you're not bound to curl, you might want to use wget in recursive mode but restricting it to one level of recursion, try the following;
wget --no-verbose --no-parent --recursive --level=1\
--no-directories --user=login --password=pass ftp://ftp.myftpsite.com/
--no-parent
: Do not ever ascend to the parent directory when retrieving recursively.--level=depth
: Specify recursion maximum depth level depth. The default maximum depth is five layers.--no-directories
: Do not create a hierarchy of directories when retrieving recursively.You could try to force the browser to open a "Save As..." dialog by doing something like:
header('Content-type: text/csv');
header('Content-disposition: attachment;filename=MyVerySpecial.csv');
echo "cell 1, cell 2";
Which should work across most major browsers.
At first you should create constructor like this
constructor(props) {
super(props);
this.state = {
close: true,
};
}
yourFunction = () => {
this.setState({
close: !this.state.close,
});
};
then use this like
render() {
const {close} = this.state;
return (
<Fragment>
<div onClick={() => this.yourFunction()}></div>
<div className={close ? "isYourDefaultClass" : "isYourOnChangeClass"}></div>
</Fragment>
)
}
}

if you used List object and passed to the adapter you can remove the value from the List object and than call the notifyDataSetChanged() using adapter object.
for e.g.
List<String> list = new ArrayList<String>();
ArrayAdapter adapter;
adapter = new ArrayAdapter<String>(DeleteManyTask.this,
android.R.layout.simple_list_item_1,
(String[])list.toArray(new String[0]));
listview = (ListView) findViewById(R.id.list);
listview.setAdapter(adapter);
listview.setAdapter(listAdapter);
for remove do this way
list.remove(index); //or
list.clear();
adpater.notifyDataSetChanged();
or without list object remove item from list.
adapter.clear();
adpater.notifyDataSetChanged();
Scenario: changing the submodule from directory dirA-xxx to another directory dirB-xxx
run git submodule status
if return error: No submodule mapping found in .gitmodules for path dirA-xxx. This is due to dirA-xxx is not existing, yet it is still tracked by git. Update the git index by: git rm --cached dirA-xxx
Try with git submodule foreach git pull
.
I didn't go through the actual study of git submodule structure, so above steps may break something. Nonetheless going through above steps, things look good at the moment. If you have any insight or proper steps to get thing done, do share it here. :)
Use the File.Copy method instead
eg.
File.Copy(@"C:\oldFile.txt", @"C:\newFile.txt");
You can call it whatever you want in the newFile, and it will rename it accordingly.
Lambdas in Python are fairly restrictive with regard to what you're allowed to use. Specifically, you can't have any keywords (except for operators like and
, not
, or
, etc) in their body.
So, there's no way you could use a lambda for your example (because you can't use raise
), but if you're willing to concede on that… You could use:
f = lambda x: x == 2 and x or None
I would rather include the factory as dependencies on the controllers than inject them with their own line of code: http://jsfiddle.net/XqDxG/550/
myModule.factory('mySharedService', function($rootScope) {
return sharedService = {thing:"value"};
});
function ControllerZero($scope, mySharedService) {
$scope.thing = mySharedService.thing;
ControllerZero.$inject = ['$scope', 'mySharedService'];
If you are importing file1.py
from file2.py
and used this:
if __name__ == '__main__':
# etc
Variables below that in file1.py
cannot be imported to file2.py
because __name__
does not equal __main__
!
If you want to import something from file1.py
to file2.py
, you need to use this in file1.py
:
if __name__ == 'file1':
# etc
In case of doubt, make an assert
statement to determine if __name__=='__main__'
Here's the better answer:
You can't implement a button clicked event for button cells in a DataGridViewButtonColumn. Instead, you use the DataGridView's CellClicked event and determine if the event fired for a cell in your DataGridViewButtonColumn. Use the event's DataGridViewCellEventArgs.RowIndex property to find out which row was clicked.
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e) {
// Ignore clicks that are not in our
if (e.ColumnIndex == dataGridView1.Columns["MyButtonColumn"].Index && e.RowIndex >= 0) {
Console.WriteLine("Button on row {0} clicked", e.RowIndex);
}
}

It's called a destructor/finalizer, and is usually created when implementing the Disposed pattern.
It's a fallback solution when the user of your class forgets to call Dispose, to make sure that (eventually) your resources gets released, but you do not have any guarantee as to when the destructor is called.
In this Stack Overflow question, the accepted answer correctly shows how to implement the dispose pattern. This is only needed if your class contain any unhandeled resources that the garbage collector does not manage to clean up itself.
A good practice is to not implement a finalizer without also giving the user of the class the possibility to manually Disposing the object to free the resources right away.

The official Jenkins documentation only mentions single line commands like the following:
// Declarative //
and (see)
pipeline {
/* insert Declarative Pipeline here */
}
The syntax of the Jenkinsfile is based on Groovy so it is also possible to use groovy syntax for comments. Quote:
/* a standalone multiline comment
spanning two lines */
println "hello" /* a multiline comment starting
at the end of a statement */
println 1 /* one */ + 2 /* two */
or
/**
* such a nice comment
*/

I had the same error. Basically, I suspect that the path cannot start either with "U" or "User" after "C:\". I changed my directory to "c:\file_name.png" by putting the file that I want to access from python right under the 'c:\' path.
In your case, if you have to access the "python" folder, perhaps reinstall the python, and change the installation path to something like "c:\python". Otherwise, just avoid the "...\User..." in your path, and put your project under C:.
