You can use a Spring-EL expression, for eg on JDK 1.7:
@Cacheable(value="bookCache", key="T(java.util.Objects).hash(#p0,#p1, #p2)")
Not 100%; however, it sounds like the heap is an object or set of allocated space (on RAM) that is built into the functionality of the code either Java itself or more likely functionality from ehcache itself, and the off-heap Ram is there own system as well; however, it sounds like this is one magnitude slower as it is not as organized, meaning it may not use a heap (meaning one long set of space of ram), and instead uses different address spaces likely making it slightly less efficient.
Then of course the next tier lower is hard-drive space itself.
I don't use ehcache, so you may not want to trust me, but that what is what I gathered from their documentation.
This is the simple example to use both of them:
import {
Directive, HostListener, HostBinding
}
from '@angular/core';
@Directive({
selector: '[Highlight]'
})
export class HighlightDirective {
@HostListener('mouseenter') mouseover() {
this.backgroundColor = 'green';
};
@HostListener('mouseleave') mouseleave() {
this.backgroundColor = 'white';
}
@HostBinding('style.backgroundColor') get setColor() {
return this.backgroundColor;
};
private backgroundColor = 'white';
constructor() {}
}
Introduction:
HostListener can bind an event to the element.
HostBinding can bind a style to the element.
this is directive, so we can use it for
Some TextSo according to the debug, we can find that this div has been binded style = "background-color:white"
Some Textwe also can find that EventListener of this div has two event: mouseenter
and mouseleave
. So when we move the mouse into the div, the colour will become green, mouse leave, the colour will become white.
A simple alternative solution:
Paste the URL into a json to csv converter
Open the CSV file in either Excel or Open Office
Use the spreadsheet tools to parse the data
"Renaming" a remote branch is actually a 2 step process (not necessarily ordered):
git push [space]:<old_name>
as ksrb explained);I use TortoiseGit and when I first tried to delete the branch through the command line, I got this:
$ git push origin :in
fatal: 'origin' does not appear to be a git repository
fatal: Could not read from remote repository.
Please make sure you have the correct access rights and the repository exists.
This was likely due to pageant not having the private key loaded (which TortoiseGit loads automatically into pageant). Moreover, I noticed that TortoiseGit commands do not have the origin
ref in them (e.g. git.exe push --progress "my_project" interesting_local:interesting
).
I am also using Bitbucket and, as others web-based online git managers of the sort (GitHub, GitLab), I was able to delete the remote branch directly through their interface (branches page):
However, in TortoiseGit you may also delete remote branches through Browse References:
By right-clicking on a remote branch (remotes list) the Delete remote branch option shows up:
After deleting the old remote branch I pushed directly into a new remote branch through TortoiseGit just by typing the new name in the Remote: field of the Push window and this branch was automatically created and visible in Bitbucket.
However, if you still prefer to do it manually, a point that has not been mentioned yet in this thread is that -u
= --set-upstream
.
From git push
docs, -u
is just an alias of --set-upstream
, so the commands in the answers of Sylvain (-set-upstream new-branch
) and Shashank (-u origin new_branch
) are equivalent, since the remote ref defaults to origin
if no other ref was previously defined:
git push origin -u new_branch
= git push -u new_branch
from the docs description:
If the configuration is missing, it defaults to
origin
.
In the end, I did not manually type in or used any of the commands suggested by the other answers in here, so perhaps this might be useful to others in a similar situation.
I'll assume that uninstall and reinstall Tomcat is not acceptable to you. The screen shot show basic auth challenge screen from browser and on the default app. So most likely you have set up users on the tomcat using the conf/tomcat-users.xml Try going through this guide https://tomcat.apache.org/tomcat-7.0-doc/realm-howto.html#UserDatabaseRealm
There are several other realms that you could have possibly used. Hopefully you will remember when you start reading the doc

I don't know is there any method in Python API.But you can use this simple code to add Salt-and-Pepper noise to an image.
import numpy as np
import random
import cv2
def sp_noise(image,prob):
'''
Add salt and pepper noise to image
prob: Probability of the noise
'''
output = np.zeros(image.shape,np.uint8)
thres = 1 - prob
for i in range(image.shape[0]):
for j in range(image.shape[1]):
rdn = random.random()
if rdn < prob:
output[i][j] = 0
elif rdn > thres:
output[i][j] = 255
else:
output[i][j] = image[i][j]
return output
image = cv2.imread('image.jpg',0) # Only for grayscale image
noise_img = sp_noise(image,0.05)
cv2.imwrite('sp_noise.jpg', noise_img)
java.exe is the command where it waits for application to complete untill it takes the next command. javaw.exe is the command which will not wait for the application to complete. you can go ahead with another commands.
you can define it like this :
let table = $('.datatable-sales').DataTable({
processing: true,
responsive: true,
serverSide: true,
ajax: {
url: "<?php echo site_url("your url"); ?>",
cache: false,
type: "POST",
data: {
<?php echo your api; ?>,
}
}
or like this :
$.get({url: <?php echo json_encode(site_url('your api'))?>, cache: false})
hope it helps
I would recommend a combination of PatIndex and Left. Carefully constructed, you can write a query that always works, no matter what your data looks like.
Ex:
Declare @Temp Table(Data VarChar(20))
Insert Into @Temp Values('BTA200')
Insert Into @Temp Values('BTA50')
Insert Into @Temp Values('BTA030')
Insert Into @Temp Values('BTA')
Insert Into @Temp Values('123')
Insert Into @Temp Values('X999')
Select Data, Left(Data, PatIndex('%[0-9]%', Data + '1') - 1)
From @Temp
PatIndex will look for the first character that falls in the range of 0-9, and return it's character position, which you can use with the LEFT function to extract the correct data. Note that PatIndex is actually using Data + '1'. This protects us from data where there are no numbers found. If there are no numbers, PatIndex would return 0. In this case, the LEFT function would error because we are using Left(Data, PatIndex - 1). When PatIndex returns 0, we would end up with Left(Data, -1) which returns an error.
There are still ways this can fail. For a full explanation, I encourage you to read:
Extracting numbers with SQL Server
That article shows how to get numbers out of a string. In your case, you want to get alpha characters instead. However, the process is similar enough that you can probably learn something useful out of it.
Try:
sudo service mongod stop
sudo mongod
To stop current active mongodb service, allowing you to then start a new one
I would think Eigenface, which you are doing already, is the way to go if you want to calculate the distance between faces. You could try out different approaches like Support Vector Machine or Hidden Markov Model. I found a page that lists major algorithms that could be used for facial recognition: Face Recognition Homepage.
Also, when you say "better performance," do you mean speed or accuracy? What kind of problem are you having? How varying are the data? Are they mostly frontal face or do they include profiles?
If you're using nmap, MAC addresses are only available if you're on the same network segment as the target. Newer versions of nmap will only show the MAC address to you if you're running as root.
i.e.:
sudo nmap -sP -n 192.168.0.0/24
date -j -f "%Y-%m-%d" "2010-10-02" "+%s"
The following example using the iris dataset works fine:
dat = melt(subset(iris, select = c("Sepal.Length","Sepal.Width", "Species")),
id.vars = "Species")
ggplot(aes(x = 1:nrow(iris), y = value, color = variable), data = dat) +
geom_point() + geom_line()
A working example.
DECLARE @TableName AS VARCHAR(100)
SELECT @TableName = 'YourTableName'
EXECUTE ('SELECT * INTO #TEMP FROM ' + @TableName +'; SELECT * FROM #TEMP;')
Second solution with accessible temp table
DECLARE @TableName AS VARCHAR(100)
SELECT @TableName = 'YOUR_TABLE_NAME'
EXECUTE ('CREATE VIEW vTemp AS
SELECT *
FROM ' + @TableName)
SELECT * INTO #TEMP FROM vTemp
--DROP THE VIEW HERE
DROP VIEW vTemp
/*START USING TEMP TABLE
************************/
--EX:
SELECT * FROM #TEMP
--DROP YOUR TEMP TABLE HERE
DROP TABLE #TEMP
As it was said you have a unique index.
However, when I added most of the list yesterday I didn't get this error once even though a lot of the entries I added yesterday have a blank cell in column 2 as well. Whats going on?
That means that all these entries contain value NULL
, not empty string ''
. Mysql lets you have multiple NULL
values in unique fields.
if using /bin/sh
you can use:
if [ <condition> ] && [ <condition> ]; then
...
fi
if using /bin/bash
you can use:
if [[ <condition> && <condition> ]]; then
...
fi
Try this, it works.

in my particular example i have a stick that have also a card reader build in it and i can see only the stick using fdisk:

I am not sure I understood your question, but if you write:
mask_data[:3, :3] = 1
mask_data[3:, 3:] = 0
This will make all values of mask data whose x and y indexes are less than 3 to be equal to 1 and all rest to be equal to 0

When using in Maven, update artifact junit:junit from e.g. 4.8.2 to 4.11.
I strongly suspect that's because of the network connection or the web server you're talking to - it's not BufferedReader
's fault. Try measuring this:
InputStream stream = conn.getInputStream();
byte[] buffer = new byte[1000];
// Start timing
while (stream.read(buffer) > 0)
{
}
// End timing
I think you'll find it's almost exactly the same time as when you're parsing the text.
Note that you should also give InputStreamReader
an appropriate encoding - the platform default encoding is almost certainly not what you should be using.
If you still haven't resolved this issue - like me - here is what caused this error for me. As @jkyoutsey suggested, I was indeed trying to create a modal component. I spent considerable time following his suggestions by moving my component to a service and injecting it into the page component. Also changing providedIn: 'root' to MyModule, which of course had to be moved at least one level up to avoid a circular reference. I'm not all together sure any of that actually was necessary.
What finally solved the 8-hour long puzzle was to NOT implement ngOnInit in my component. I had blindly implemented ngOnInit even though the function was empty. I tend to do that. It's probably a bad practice.
Anyway, if someone could shed light on why an empty ngOnInit would have caused this error, I'd love to read the comments.
Keep it simple and clean
var d = new Date();
var n = d.toLocaleString();
Use the DateTime object ToString with a custom format string like myDate.ToString("MM/dd/yy") for example.
According to the C99 spec,
NULL
expands to a null pointer constant, which is not required to be, but typically is of type void *
'\0'
is a character constant; character constants are of type int
, so it's equivalen to plain 0
"\0"
is a null-terminated string literal and equivalent to the compound literal (char [2]){ 0, 0 }
NULL
, '\0'
and 0
are all null pointer constants, so they'll all yield null pointers on conversion, whereas "\0"
yields a non-null char *
(which should be treated as const
as modification is undefined); as this pointer may be different for each occurence of the literal, it can't be used as sentinel value.
Although you may use any integer constant expression of value 0
as a null pointer constant (eg '\0'
or sizeof foo - sizeof foo + (int)0.0
), you should use NULL
to make your intentions clear.
To keep it in one line use:
git add . && git commit -am "comment"
This line will add and commit all changed and added files to repository.
The simple answer is onPressed : null
gives a disabled button.
I had to return a rtf file and this worked for me.
// create a byte array of the file in correct format
byte[] docStream = createDoc(fragments);
return Response

.header("content-disposition","attachment; filename = doc.rtf")
.build();
Well you can simply use this piece of code in your scss file; This will remove that unwanted color change,
a:-webkit-any-link {
&:hover {
color: white;
}
}
String b = "[" + readlocationFeed + "]";
JSONArray jsonArray1 = new JSONArray(b);
jsonarray_length1 = jsonArray1.length();
for (int i = 0; i < jsonarray_length1; i++) {
}
or convert it in JSONOBJECT
JSONObject jsonobj = new JSONObject(readlocationFeed);
JSONArray jsonArray = jsonobj.getJSONArray("locations");
Use modulus:
function isEven(n) {
return n % 2 == 0;
}
function isOdd(n) {
return Math.abs(n % 2) == 1;
}
You can check that any value in Javascript can be coerced to a number with:
Number.isFinite(parseFloat(n))
This check should preferably be done outside the isEven
and isOdd
functions, so you don't have to duplicate error handling in both functions.
You can use this code...
public class Main {
public static void main(String args[]) {
String[] names = {"First", "Second", "Third"};//You Can Add More Names
double[] amount = {20.0, 30.0, 40.0};//You Can Add More Amount
List<Customer> customers = new ArrayList<Customer>();
int i = 0;
while (i < names.length) {
customers.add(new Customer(names[i], amount[i]));
i++;
}
}
}
You could also do this:
$dump = print_r($variable, true);
Although maven exec does the trick here, I found it pretty poor for a real test. While waiting for maven shell, and hoping this could help others, I finally came out to this repo mvnexec
Clone it, and symlink the script somewhere in your path. I use ~/bin/mvnexec
, as I have ~/bin
in my path. I think mvnexec is a good name for the script, but is up to you to change the symlink...
Launch it from the root of your project, where you can see src and target dirs.
The script search for classes with main method, offering a select to choose one (Example with mavenized JMeld project)
$ mvnexec
1) org.jmeld.ui.JMeldComponent
2) org.jmeld.ui.text.FileDocument
3) org.jmeld.JMeld
4) org.jmeld.util.UIDefaultsPrint
5) org.jmeld.util.PrintProperties
6) org.jmeld.util.file.DirectoryDiff
7) org.jmeld.util.file.VersionControlDiff
8) org.jmeld.vc.svn.InfoCmd

#?
If one is selected (typing number), you are prompt for arguments (you can avoid with mvnexec -P
)
By default it compiles project every run. but you can avoid that using mvnexec -B
It allows to search only in test classes -M
or --no-main
, or only in main classes -T
or --no-test
. also has a filter by name option -f <whatever>
Hope this could save you some time, for me it does.
you'd use any of these:
JSTL c:forEach varStatus properties
Property Getter Description
current getCurrent() The item (from the collection) for the current round of iteration.
index getIndex() The zero-based index for the current round of iteration.
count getCount() The one-based count for the current round of iteration
last isLast() Flag indicating whether the current round is the last pass through the iteration
begin getBegin() The value of the begin attribute
end getEnd() The value of the end attribute
step getStep() The value of the step attribute
You can use the below code to select columns based on their index (position). You can alter the numbers for variable colNos to select only those columns
import org.apache.spark.sql.functions.col
val colNos = Seq(0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35)
val Df_01 = Df.select(colNos_01 map Df.columns map col: _*)
Df_01.show(20, false)
You are calling DoDownloadAsync() but you don't wait it. So your program going to the next line. But there is another problem, Async methods should return Task
or Task<T>
, if you return nothing and you want your method will be run asyncronously you should define your method like this:
private static async Task DoDownloadAsync() { WebClient w = new WebClient(); string txt = await w.DownloadStringTaskAsync("http://www.google.com/"); Debug.WriteLine(txt); }
And in Main method you can't await for DoDownloadAsync
, because you can't use await keyword in non-async function, and you can't make Main
async. So consider this:
var result = DoDownloadAsync(); Debug.WriteLine("DoDownload done"); result.Wait();
Firstly, the level name to use is FINE
, not DEBUG
. Let's assume for a minute that DEBUG
is actually valid, as it makes the following explanation make a bit more sense...
In the Handler specific properties
section, you're setting the logging level for those handlers to DEBUG
. This means the handlers will handle any log messages with the DEBUG
level or higher. It doesn't necessarily mean any DEBUG
messages are actually getting passed to the handlers.
In the Facility specific properties
section, you're setting the logging level for a few explicitly-named loggers to DEBUG
. For those loggers, anything at level DEBUG
or above will get passed to the handlers.
The default logging level is INFO
, and apart from the loggers mentioned in the Facility specific properties
section, all loggers will have that level.
If you want to see all FINE
messages, add this:
.level = FINE
However, this will generate a vast quantity of log messages. It's probably more useful to set the logging level for your code:
your.package.level = FINE
See the Tomcat 6/Tomcat 7 logging documentation for more information. The example logging.properties file shown there uses FINE
instead of DEBUG
:
...
1catalina.org.apache.juli.FileHandler.level = FINE
...
and also gives you examples of setting additional logging levels:
# For example, set the com.xyz.foo logger to only log SEVERE
# messages:
#org.apache.catalina.startup.ContextConfig.level = FINE
#org.apache.catalina.startup.HostConfig.level = FINE
#org.apache.catalina.session.ManagerBase.level = FINE
This is a security update. If an attacker can modify some file in the web server (the JS one, for example), he can make every loaded pages to download another script (for example to keylog your password or steal your SessionID and send it to his own server).
To avoid it, the browser check the Same-origin policy
Your problem is that the browser is trying to load something with your script (with an Ajax request) that is on another domain (or subdomain). To avoid it (if it is on your own website) you can:
I found this version most suitable for all cases. It doesn't remove all whitespaces.
For example "a (test) b" -> "a b"
"Hello, this is Mike (example)".replace(/ *\([^)]*\) */g, " ").trim();
"Hello, this is (example) Mike ".replace(/ *\([^)]*\) */g, " ").trim();
ERROR 2005 (HY000): Unknown MySQL server host 'localhost' (0)
modify list of host names for your system:
C:\Windows\System32\drivers\etc\hosts
Make sure that you have the following entry:
127.0.0.1 localhost
In my case that entry was 0.0.0.0 localhost which caussed all problem
(you may need to change modify permission to modify this file)
This performs DNS resolution of host “localhost” to the IP address 127.0.0.1.
Code summary:
using System.Windows.Forms;
...
MessageBox.Show( "hello world" );
Also (as per this other stack post): In Visual Studio expand the project in Solution Tree, right click on References, Add Reference, Select System.Windows.Forms
on Framework tab. This will get the MessageBox working in conjunction with the using System.Windows.Forms reference from above.
In the controller action append to the header the following lines
public ActionResult Create(string PositionID)
{
Response.AppendHeader("Cache-Control", "no-cache, no-store, must-revalidate"); // HTTP 1.1.
Response.AppendHeader("Pragma", "no-cache"); // HTTP 1.0.
Response.AppendHeader("Expires", "0"); // Proxies.
I just posted a fix here that would also apply in this case - basically, you do a hex find-and-replace in your external library to make it think that it's ARMv7s code. You should be able to use lipo
to break it into 3 static libraries, duplicate / modify the ARMv7 one, then use lipo
again to assemble a new library for all 4 architectures.
Here are a couple: http://www.amp-what.com/unicode/search/check%20mark

Thank you for this thread. I've been having a hard time implementing a Timer in my code for 5 minutes to run an activity, because my phone I have set to screen off/sleep around 2 minutes. With the above information it appears I have been able to get the work around.
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/* Time Lockout after 5 mins */
getWindow().addFlags(LayoutParams.FLAG_KEEP_SCREEN_ON);
Timer timer = new Timer();
timer.schedule(new TimerTask() {
public void run() {
Intent i = new Intent(AccountsList.this, AppEntryActivity.class);
i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);
finish();
return;
}
}, 300000);
/* Time Lockout END */
}
Based on your requirement that you want to put a border around an arbitrary block of MxN cells there really is no easier way of doing it without using Javascript. If your cells are fixed with you can use floats but this is problematic for other reasons. what you're doing may be tedious but it's fine.
Ok, if you're interested in a Javascript solution, using jQuery (my preferred approach), you end up with this fairly scary piece of code:
<html>
<head>
<style type="text/css">
td.top { border-top: thin solid black; }
td.bottom { border-bottom: thin solid black; }
td.left { border-left: thin solid black; }
td.right { border-right: thin solid black; }
</style>

}
if (typeof width == 'undefined') {
width = 1;
}
$("table").each(function() {
$("tr:nth-child(" + row + ")", this).children().slice(col - 1, col + width - 1).addClass("top");

I'll happily take suggestions on easier ways to do this...
If-elseif-else can be written as a nested if-else. These are (logically speaking) equivalent:
if (A)
{
doA();
}
else if (B)
{
doB();
}
else if (C)
{
doC();
}
else
{
doX();
}
is the same as:
if (A)
{
doA();
}
else
{
if (B)
{
doB();
}
else
{
if (C)
{
doC();
}
else
{
doX();
}
}
}
The result is that ultimately only one of doA
, doB
, doC
, or doX
will be evaluated.
In component.ts add this function
_keyUp(event: any) {
const pattern = /[0-9\+\-\ ]/;
let inputChar = String.fromCharCode(event.key);
if (!pattern.test(inputChar)) {
// invalid character, prevent input
event.preventDefault();
}
}
In your template use the following
<input(keyup)="_keyUp($event)">
This will catch the input before angular2 catches the event.
The issue is that you haven't got command line tools installed, I believe. Try run in terminal:
sudo gem update --system
after that download command line tools from Apple just search for 'Command Line Tools' and download the right version for your OS. Once you install it run in terminal:
sudo gem install cocoapods
pod setup
You can also download swagger ui from: https://github.com/swagger-api/swagger-ui, take the dist folder, modify index.html: change the constructor
const ui = SwaggerUIBundle({
url: ...,
into
const ui = SwaggerUIBundle({
spec: YOUR_JSON,
now the dist folder contains all what you need and can be distributed as is
Use the map
function in pipe
function and it will solve your problem.
You can check the documentation here.
this.items = this.afs.collection('blalal').snapshotChanges().pipe(map(changes => {
return changes.map(a => {
const data = a.payload.doc.data() as Items;
data.id = a.payload.doc.id;
return data;
})
})
In C# 5 you can get that information using caller info:
//using System.Runtime.CompilerServices;
public void SendError(string Message, [CallerMemberName] string callerName = "")
{
Console.WriteLine(callerName + "called me.");
}
You can also get the [CallerFilePath]
and [CallerLineNumber]
.
In case it helps anyone else - my issue was a rookie error, I had a space in the name line of my package.json and it caused the dependencies to be unreadable.
I encountered a similar problem like this, problem was with the backend . I was using node server(Express). I had a get request from the frontend(angular) as shown below
onGetUser(){
return this.http.get("http://localhost:3000/user").pipe(map(
(response:Response)=>{
const user =response.json();
return user;
}
))
}
But it gave the following error
This is the backend code written using express without the headers
app.get('/user',async(req,res)=>{
const user=await getuser();
res.send(user);
})
After adding a header to the method problem was solved
app.get('/user',async(req,res)=>{
res.header("Access-Control-Allow-Origin", "*");
const user=await getuser();
res.send(user);
})

Not really, because as you say, the compiler only knows that callFriend() is returning an Animal, not a Dog or Duck.
Can you not add an abstract makeNoise() method to Animal that would be implemented as a bark or quack by its subclasses?
I don't like very much iterator's semantic, please consider this as an option. It's also safer as you publish less of your internal state
private Map<String, String> JSONtoMAP(String jsonString) {
JSONObject json = new JSONObject(jsonString);
Map<String, String> outMap = new HashMap<String, String>();
for (String curKey : (Set<String>) json.keySet()) {
outMap.put(curKey, json.getString(curKey));
}
return outMap;
}
I too had the same issue and I believe the code below is more simple and it is working for me,
public class MultiReadHttpServletRequest extends HttpServletRequestWrapper {
private String _body;
public MultiReadHttpServletRequest(HttpServletRequest request) throws IOException {
super(request);
_body = "";
BufferedReader bufferedReader = request.getReader();
String line;
while ((line = bufferedReader.readLine()) != null){
_body += line;
}
}
@Override
public ServletInputStream getInputStream() throws IOException {
final ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(_body.getBytes());
return new ServletInputStream() {
public int read() throws IOException {
return byteArrayInputStream.read();
}
};
}
@Override
public BufferedReader getReader() throws IOException {
return new BufferedReader(new InputStreamReader(this.getInputStream()));
}
}
in the filter java class,
HttpServletRequest properRequest = ((HttpServletRequest) req);
MultiReadHttpServletRequest wrappedRequest = new MultiReadHttpServletRequest(properRequest);
req = wrappedRequest;
inputJson = IOUtils.toString(req.getReader());
System.out.println("body"+inputJson);
Please let me know if you have any queries
Since some of the other answers include info on rebuilding, and my use case also required a rebuild, I had a better solution (compared to those).
There's still a way to easily target just the one single worker
container that both rebuilds + restarts it in a single line, albeit it's not actually a single command. The best solution for me was simply rebuild and restart:
docker-compose build worker && docker-compose restart worker
This accomplishes both major goals at once for me:
worker
containerHope this helps anyone else getting here.
A rather roundabout way, just for completeness:
for /f "delims=" %i in ('type CON') do set inp=%i
Of course that requires ^Z as a terminator, and so the Johannes answer is better in all practical ways.
look at it is informative [Qualified identifiers
A qualified id-expression is an unqualified id-expression prepended by a scope resolution operator ::, and optionally, a sequence of enumeration, (since C++11)class or namespace names or decltype expressions (since C++11) separated by scope resolution operators. For example, the expression std::string::npos is an expression that names the static member npos in the class string in namespace std. The expression ::tolower names the function tolower in the global namespace. The expression ::std::cout names the global variable cout in namespace std, which is a top-level namespace. The expression boost::signals2::connection names the type connection declared in namespace signals2, which is declared in namespace boost.
The keyword template may appear in qualified identifiers as necessary to disambiguate dependent template names]1

This helped me get to my answer. There are two php.ini
files located, in my case, for wamp. One is under the php folder and the other one is in the C:\wamp\bin\apache\Apachex.x.x\bin
folder. When connecting to SQL through sqlsrv_connect
function, we are referring to the php.ini
file in the apache
folder. Add the following (as per your version) to this file:
extension=c:/wamp/bin/php/php5.4.16/ext/php_sqlsrv_53_ts.dll
The numeric type overview for MySQL states: BOOL, BOOLEAN: These types are synonyms for TINYINT(1). A value of zero is considered false. Nonzero values are considered true.

Find highest number, including negative:

Using Guava library:
int size = Iterators.size(iterator);
Internally it just iterates over all elements so its just for convenience.

I faced a problem upgrading pip from version 9.0.1 to 9.0.3 The upgrade failed middle way(after uninstalling version 9.0.1 and without installing version 9.0.3). This usually creates a broken pip file. Broken pip can be solved by the command-->
easy_install pip
Which usually installs the latest version of pip, and solves the issue. In order to confirm, type
pip --version
Hope this was helpfull...
Here:
$file = 'http://www.example.com/somefile.jpg';
$file_headers = @get_headers($file);
if(!$file_headers || $file_headers[0] == 'HTTP/1.1 404 Not Found') {
$exists = false;
}
else {
$exists = true;
}
From here and right below the above post, there's a curl solution:
function url_exists($url) {
return curl_init($url) !== false;
}
One more option - mod_qos
Not simple to configure - but powerful.
Dictionaries have a built in function called iterkeys()
.
Try:
for team in league.iterkeys():
runs_scored = float(league[team][0])
runs_allowed = float(league[team][1])
win_percentage = round((runs_scored**2)/((runs_scored**2)+(runs_allowed**2))*1000)
print win_percentage
Maybe it help you. I use this in my app

Using ruby 2.4 you can do the same thing using transform_values
, this feature extracted from rails to ruby.
h = {a: 1, b: 2, c: 3}
h.transform_values { |v| v * 10 }
#=> {a: 10, b: 20, c: 30}
I think this is the easiest way to do it.
static bool IsPrime(int number)
{
for (int i = 2; i <= number/2; i++)
if (number % i == 0)
return false;
return true;
}
in file .xml, set
android:textStyle="bold"
will set text type is bold.
When a
and b
are 1-dimensional sequences, numpy.cov(a,b)[0][1]
is equivalent to your cov(a,b)
.
The 2x2 array returned by np.cov(a,b)
has elements equal to
cov(a,a) cov(a,b)
cov(a,b) cov(b,b)
(where, again, cov
is the function you defined above.)
Now, is more easy with HTML 5 and CSS 3:

First, you need to create selfsigned.key and selfsigned.crt files. Go to Create a Self-Signed SSL Certificate Or do following steps.
Go to the terminal and run the following command.
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout ./selfsigned.key -out selfsigned.crt
After creation adds key & cert file in your code, and pass the options to the server.
const express = require('express');
const https = require('https');
const fs = require('fs');
const port = 3000;
var key = fs.readFileSync(__dirname + '/../certs/selfsigned.key');
var cert = fs.readFileSync(__dirname + '/../certs/selfsigned.crt');
var options = {
key: key,
cert: cert
};
app = express()
app.get('/', (req, res) => {
res.send('Now using https..');
});
var server = https.createServer(options, app);
server.listen(port, () => {
console.log("server starting on port : " + port)
});

The output of Get-Service
is a System.ServiceProcess.ServiceController
.NET class that can operate on remote computers. How it accomplishes that, I don't know - probably DCOM or WMI. Once you've gotten one of these from Get-Service
, it can be passed into Stop-Service
which most likely just calls the Stop()
method on this object. That stops the service on the remote machine. In fact, you could probably do this as well:
(get-service -ComputerName remotePC -Name Spooler).Stop()
text= re.sub('[0-9\n]',' ',text)
install regex in python which is re then do the following code.
You need commas after end
finishing the case statement. And, the "as" goes after the case
statement, not inside it:
Insert into TblStuff(FullName, Address, City, Zip)
Select (Case When Middle is Null Then Fname + LName
Else Fname +' ' + Middle + ' '+ Lname
End) as FullName,
(Case When Address2 is Null Then Address1
else Address1 +', ' + Address2
End) as Address,
City as City,
Zip as Zip

The SQLite equivalent of anything this robust is a tangled weave of substr
and instr
calls that you should avoid.
Angular has several timepoints to start executing functions. If you seek for something like jQuery's
$(document).ready();
You may find this analog in angular to be very useful:
$scope.$watch('$viewContentLoaded', function(){
//do something
});
This one is helpful when you want to manipulate the DOM elements. It will start executing only after all te elements are loaded.
UPD: What is said above works when you want to change css properties. However, sometimes it doesn't work when you want to measure the element properties, such as width, height, etc. In this case you may want to try this:
$scope.$watch('$viewContentLoaded',
function() {
$timeout(function() {
//do something
},0);
});
@Zelazny7's answer works, but if you want to keep ties you could do:
df[which(df$Amount == min(df$Amount)), ]
For example with the following data frame:
df <- data.frame(Name = c("A", "B", "C", "D", "E"),
Amount = c(150, 120, 175, 160, 120))
df[which.min(df$Amount), ]
# Name Amount
# 2 B 120
df[which(df$Amount == min(df$Amount)), ]
# Name Amount
# 2 B 120
# 5 E 120
Edit: If there are NAs in the Amount
column you can do:
df[which(df$Amount == min(df$Amount, na.rm = TRUE)), ]
I've used this request to delete all my records but sometimes it's necessary to commit this.
For that, add &commit=true
to your request :
http://host:port/solr/core/update?stream.body=<delete><query>*:*</query></delete>&commit=true
If you're using Chrome you can't see enough information in the standard Chrome networking panel to determine the root cause of a (canceled)
request.
You need to use chrome://net-internals/#events
which will show you the gory detail of the request you are sending - including hidden redirects / security information about cookies being sent etc.
e.g. the following shows a redirect I wasn't seeing in the network trace - caused by my cookies not being sent cross sub-domain:
t=1374052796448 [st= 1] +URL_REQUEST_START_JOB [dt=261]

I haven't studied yet, when Maven does which look-up, but to get stable and reproducible builds, I strongly recommend not to access Maven Respositories directly but to use a Maven Repository Manager such as Nexus.

You should be able to set these via the attr()
or prop()
functions in jQuery as shown below:
jQuery (< 1.7):
// This will disable just the div
$("#dcacl").attr('disabled','disabled');
or
// This will disable everything contained in the div
$("#dcacl").children().attr("disabled","disabled");
jQuery (>= 1.7):
// This will disable just the div
$("#dcacl").prop('disabled',true);
or
// This will disable everything contained in the div
$("#dcacl").children().prop('disabled',true);
or
// disable ALL descendants of the DIV
$("#dcacl *").prop('disabled',true);
Javascript:
// This will disable just the div
document.getElementById("dcalc").disabled = true;
or
// This will disable all the children of the div
var nodes = document.getElementById("dcalc").getElementsByTagName('*');
for(var i = 0; i < nodes.length; i++){
nodes[i].disabled = true;
}
You can use TreeMap which internally implements the SortedMap below is the example
Sorting by ascending ordering :
Map<Float, String> ascsortedMAP = new TreeMap<Float, String>();
ascsortedMAP.put(8f, "name8");
ascsortedMAP.put(5f, "name5");
ascsortedMAP.put(15f, "name15");
ascsortedMAP.put(35f, "name35");
ascsortedMAP.put(44f, "name44");
ascsortedMAP.put(7f, "name7");
ascsortedMAP.put(6f, "name6");
for (Entry<Float, String> mapData : ascsortedMAP.entrySet()) {
System.out.println("Key : " + mapData.getKey() + "Value : " + mapData.getValue());
}
Sorting by descending ordering :
If you always want this create the map to use descending order in general, if you only need it once create a TreeMap with descending order and put all the data from the original map in.
// Create the map and provide the comparator as a argument
Map<Float, String> dscsortedMAP = new TreeMap<Float, String>(new Comparator<Float>() {
@Override
public int compare(Float o1, Float o2) {
return o2.compareTo(o1);
}

Check your build types of each project under project properties - I bet one or the other will be set to build against .NET XX - Client Profile
.
With inconsistent versions, specifically with one being Client Profile
and the other not, then it works at design time but fails at compile time. A real gotcha.
There is something funny going on in Visual Studio 2010 for me, which keeps setting projects seemingly randomly to Client Profile
, sometimes when I create a project, and sometimes a few days later. Probably some keyboard shortcut I'm accidentally hitting...
I came across a similar question when dealing with an API that accepts both XML and JSON, but doesn't document how it would handle what you'd expect to be duplicate keys in the JSON accepted.
The following is a valid XML representation of your sample JSON:
<object>
<a>x</a>
<a>y</a>
</object>
When this is converted into JSON, you get the following:
{
"object": {
"a": [
"x",
"y"
]
}
}
A natural mapping from a language that handles what you might call duplicate keys to another, can serve as a potential best practice reference here.
Hope that helps someone!
You can use toolz.merge([x, y])
for this.
Use a convert function to get all entries for a particular day.
Select * from tblErrorLog where convert(date,errorDate,101) = '12/20/2008'
See CAST and CONVERT for more info
Yes, each package must be defined in its own directory.
The source structure is defined in How to Write Go Code.
A package is a component that you can use in more than one program, that you can publish, import, get from an URL, etc. So it makes sense for it to have its own directory as much as a program can have a directory.
The only way that I was able to get the column names was using the following query:
select COLUMN_NAME
FROM all_tab_columns atc
WHERE table_name like 'USERS'
The answers above are so wrong! DO NOT add custom headers. Judging from your sample xml, it is a standard WS-Security header. WCF definitely supports it out of the box. When you add a service reference you should have basicHttpBinding binding created for you in the config file. You will have to modify it to include security element with mode TransportWithMessageCredential and message element with clientCredentialType = UserName:
<basicHttpBinding>
<binding name="usernameHttps">
<security mode="TransportWithMessageCredential">
<message clientCredentialType="UserName"/>
</security>
</binding>
</basicHttpBinding>
The config above is telling WCF to expect userid/password in the SOAP header over HTTPS. Then you can set id/password in your code before making a call:
var service = new MyServiceClient();
service.ClientCredentials.UserName.UserName = "username";
service.ClientCredentials.UserName.Password = "password";
Unless this particular service provider deviated from the standard, it should work.
For debugging purposes, you could use print(repr(data))
.
To display text, always print Unicode. Don't hardcode the character encoding of your environment such as Cp850 inside your script. To decode the HTTP response, see A good way to get the charset/encoding of an HTTP response in Python.
To print Unicode to Windows console, you could use win-unicode-console
package.
mylist[c(5,7,9)]
should do it.
You want the sublists returned as sublists of the result list; you don't use [[]]
(or rather, the function is [[
) for that -- as Dason mentions in comments, [[
grabs the element.
Even though a bit old thread, for those who still looking for the differences:
Aside from layout (space) taken in Hidden and not taken in Collapsed, there is another difference.
If we have custom controls inside this 'Collapsed' main control, the next time we set it to Visible, it will "load" all custom controls. It will not pre-load when window is started.
As for 'Hidden', it will load all custom controls + main control which we set as hidden when the "window" is started.
In my case, I used a button to show the modal
<button type="button" class="btn btn-success" style="color:white"
data-toggle="modal" data-target="#my-modal-to-show" >
<i class="fas fa-plus"></i> Call MODAL
</button>
So in my code, to close the modal (that has the id = 'my-modal-to-show') I call that function (in Angular typescript):
closeById(modalId: string) {
$(modalId).modal('toggle');
$(modalId+ ' .close').click();
}
If I call $(modalId).modal('hide') it does't work and I don't know why
PS.: in my modal I coded that button element with .close class too
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
If you still want a custom filter you can pass in the search model to the filter:
<article data-ng-repeat="result in results | cartypefilter:search" class="result">
Where definition for the cartypefilter can look like this:
app.filter('cartypefilter', function() {
return function(items, search) {
if (!search) {
return items;
}
var carType = search.carType;
if (!carType || '' === carType) {
return items;
}
return items.filter(function(element, index, array) {
return element.carType.name === search.carType;
});
};
});
Suppose the DataFrames you want to join are df1 and df2, and you are joining them on column 'a', then you have 2 methods
Method 1
df1.join(df2,'a','left_outer')
This is an awsome method and it is highly recommended.
Method 2
df1.join(df2,df1.a == df2.a,'left_outer').drop(df2.a)
I verified the following on both Python 2.7 and Python 3.8
I did print(100<<3) Converting 100 to Binary gives 1100100. What I did is I droped the first 3 bits and added 3 bits with the value '0' at the end. So it should result as 0100000, and I converted this to Decimal and the answer was 32.
For my suprise when I executed print(100<<3) the answer was 800. I was puzzled. I converted 800 to Binary to check whats going on. And this is what I got 1100100000.
If you see how 800 was Python answer, they did not shift or drop the first 3 bits but they added value '0' to last 3 bits.
Where as print(100>>3) , worked perfect. I did manual calculation and cheked the print result from python. It worked correctly. Dropped last 3 bits and added value '0' to first 3 bits.
Looks like (100<<3) , left shift operator has a bug on Python.
First of all, install the prerequisite libraries:
sudo apt-get update
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev
Then install rbenv, which is used to install Ruby:
cd
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL
git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL
rbenv install 2.3.1
rbenv global 2.3.1
ruby -v
Then (optional) tell Rubygems to not install local documentation:
echo "gem: --no-ri --no-rdoc" > ~/.gemrc

var parsedData;
try {
parsedData = JSON.parse(data)
} catch (e) {
// is not a valid JSON string
}
However, I will suggest to you that your http call / service should return always a data in the same format. So if you have an error, than you should have a JSON object that wrap this error:
{"error" : { "code" : 123, "message" : "Foo not supported" } }
And maybe use as well as HTTP status a 5xx code.
I believe it must work but any ways I'm not able to identify. Other approach can be,
<textarea (keyup)="emitWordCount(myModel)" [(ngModel)]="myModel"></textarea>
export class TextEditorComponent {
@Output() countUpdate = new EventEmitter<number>();
emitWordCount(model) {
this.countUpdate.emit(
(model.match(/\S+/g) || []).length);
}
}
gitk <path_to_filename>
Assuming the package "gitk" is already installed.
If it is not installed, do this:
sudo apt-get install gitk
And then try the above command. It is for Linux... It might help Linux users if they want a GUI.
It took me a while, but here's how I made it dynamic. It doesn't depend on a sorted table.
First I started with a column of state names (Column A) and a column of aircraft in each state (Column B). (Row 1 is a header row).
Finding the cell that contains the number of aircraft was:
=MATCH(MAX($B$2:$B$54),$B$2:$B$54,0)+MIN(ROW($B$2:$B$54))-1
I put that into a cell and then gave that cell a name, "StateRow" Then using the tips from above, I wound up with this:
=INDIRECT(ADDRESS(StateRow,1))
This returns the name of the state from the dynamic value in row "StateRow", column 1
Now, as the values in the count column change over time as more data is entered, I always know which state has the most aircraft.
For anyone still looking into this in order to learn specifically what a stack is, the term "stack" is referring to a "solution stack." A solution stack is simply a complete set of software to address a given problem, usually by combining to provide the platform or infrastructure necessary. This term is the parent of both "server stack" and "web stack." Accordingly, a LAMP stack is a specific and complete set of software specifically aimed at serving dynamic content over the web.
Some extra reading:

If you are getting this from an outside site it might be helpful to use jQuery's getJSON. If it's a list you can iterate through it with $.each
$.getJSON(url, function (json) {
alert(json.result);
$.each(json.list, function (i, fb) {
alert(fb.result);
});
});
The default port for SQL Server Database Engine is 1433.
And as a best practice it should always be changed after the installation. 1433 is widely known which makes it vulnerable to attacks.

In your controller, render the new
action from your create action if validation fails, with an instance variable, @car
populated from the user input (i.e., the params
hash). Then, in your view, add a logic check (either an if block around the form
or a ternary on the helpers, your choice) that automatically sets the value of the form fields to the params
values passed in to @car if car exists. That way, the form will be blank on first visit and in theory only be populated on re-render in the case of error. In any case, they will not be populated unless @car
is set.
Use position: relative on the parent element.
Also note that had you not added any position attributes to any of the divs you wouldn't have seen this behavior. Juan explains further.

Here is an alternative, by testing with javascript if a css rule is supported, via the native CSS support api. Might evolve, to be adapted!
Note that it's possible to pass many css rules separated by a semicolon, for the finest detection.
if (CSS.supports("( -webkit-box-reflect:unset )")){
console.log("WEBKIT BROWSER")
// More math...
} else {
console.log("ENJOY")
}
_x000D_
if (CSS.supports("( -moz-user-select:unset )")){
console.log("FIREFOX!!!")
}
_x000D_
Beware to not use it in loops, for performance it's better to populate a constant on load:
const ff = CSS.supports("( -moz-user-select:unset )")
if (ff){ //... }
Using CSS only, the above would be:
@supports (-webkit-box-reflect:unset) {
div {
background: red
}
}
@supports (-moz-user-select:unset) {
div {
background: green
}
}
_x000D_
<div>
Hello world!!
</div>
_x000D_

on Jupyter notebook, try this:
pwd #this shows the current directory
if this is not the directory you like and you would like to change, try this:
import os
os.chdir ('THIS SHOULD BE YOUR DESIRED DIRECTORY')
Then try pwd again to see if the directory is what you want.
It works for me.
Another option would be to enclose the update statement in an IF statement and call TRIGGER_NESTLEVEL() to restrict the update being run a second time.
CREATE TRIGGER Table_A_Update ON Table_A AFTER UPDATE
AS
IF ((SELECT TRIGGER_NESTLEVEL()) < 2)
BEGIN
UPDATE a
SET Date_Column = GETDATE()
FROM Table_A a
JOIN inserted i ON a.ID = i.ID
END
When the trigger initially runs the TRIGGER_NESTLEVEL is set to 1 so the update statement will be executed. That update statement will in turn fire that same trigger except this time the TRIGGER_NESTLEVEL is set to 2 and the update statement will not be executed.
You could also check the TRIGGER_NESTLEVEL first and if its greater than 1 then call RETURN to exit out of the trigger.
IF ((SELECT TRIGGER_NESTLEVEL()) > 1) RETURN;
Try:
java -cp . Echo "hello"
Assuming that you compiled with:
javac Echo.java
Then there is a chance that the "current" directory is not in your classpath ( where java looks for .class definitions )
If that's the case and listing the contents of your dir displays:
Echo.java
Echo.class
Then any of this may work:
java -cp . Echo "hello"
or
SET CLASSPATH=%CLASSPATH;.
java Echo "hello"
And later as Fredrik points out you'll get another error message like.
Exception in thread "main" java.lang.NoSuchMethodError: main

You should try and avoid jQuery in ReactJS. But if you really want to use it, you'd put it in componentDidMount() lifecycle function of the component.
e.g.
class App extends React.Component {
componentDidMount() {
// Jquery here $(...)...
}
// ...
}
Ideally, you'd want to create a reusable Accordion component. For this you could use Jquery, or just use plain javascript + CSS.
class Accordion extends React.Component {
constructor() {
super();
this._handleClick = this._handleClick.bind(this);
}
componentDidMount() {
this._handleClick();
}
_handleClick() {
const acc = this._acc.children;
for (let i = 0; i < acc.length; i++) {
let a = acc[i];
a.onclick = () => a.classList.toggle("active");
}
}
render() {
return (
<div
ref={a => this._acc = a}
onClick={this._handleClick}>
{this.props.children}
</div>
)
}
}
Then you can use it in any component like so:
class App extends React.Component {
render() {
return (
<div>
<Accordion>
<div className="accor">
<div className="head">Head 1</div>
<div className="body"></div>
</div>
</Accordion>
</div>
);
}
}

Simply put HS256

for verification but about 2 orders of magnitude faster than RS256
for issuing (signing).

First and foremost, I highly suggest using a profiler or atleast use timeit.
However if you wanted to write your own timing method strictly to learn, here is somewhere to get started using a decorator.
Python 2:
def timing(f):
def wrap(*args):
time1 = time.time()
ret = f(*args)
time2 = time.time()
print '%s function took %0.3f ms' % (f.func_name, (time2-time1)*1000.0)
return ret
return wrap
And the usage is very simple, just use the @timing decorator:
@timing
def do_work():
#code
Python 3:
def timing(f):
def wrap(*args, **kwargs):
time1 = time.time()
ret = f(*args, **kwargs)
time2 = time.time()
print('{:s} function took {:.3f} ms'.format(f.__name__, (time2-time1)*1000.0))
return ret
return wrap
Note I'm calling f.func_name
to get the function name as a string(in Python 2), or f.__name__
in Python 3.
You could do the following:
DELETE * FROM table WHERE NOT(id = 2);
When you #include
a header, it's exactly as if you put the code into the source file itself. In both cases the varGlobal
variable is defined in the source so it will work no matter how it's declared.
Also as pointed out in the comments, C++ variables at file scope are not static in scope even though they will be assigned to static storage. If the variable were a class member for example, it would need to be accessible to other compilation units in the program by default and non-class members are no different.
From this post:
To get the entire PC CPU and Memory usage:
using System.Diagnostics;
Then declare globally:
private PerformanceCounter theCPUCounter =
new PerformanceCounter("Processor", "% Processor Time", "_Total");
Then to get the CPU time, simply call the NextValue()
method:
this.theCPUCounter.NextValue();
This will get you the CPU usage
As for memory usage, same thing applies I believe:
private PerformanceCounter theMemCounter =
new PerformanceCounter("Memory", "Available MBytes");
Then to get the memory usage, simply call the NextValue()
method:
this.theMemCounter.NextValue();
For a specific process CPU and Memory usage:
private PerformanceCounter theCPUCounter =
new PerformanceCounter("Process", "% Processor Time",
Process.GetCurrentProcess().ProcessName);
where Process.GetCurrentProcess().ProcessName
is the process name you wish to get the information about.
private PerformanceCounter theMemCounter =
new PerformanceCounter("Process", "Working Set",
Process.GetCurrentProcess().ProcessName);
where Process.GetCurrentProcess().ProcessName
is the process name you wish to get the information about.
Note that Working Set may not be sufficient in its own right to determine the process' memory footprint -- see What is private bytes, virtual bytes, working set?
To retrieve all Categories, see Walkthrough: Retrieving Categories and Counters
The difference between Processor\% Processor Time
and Process\% Processor Time
is Processor
is from the PC itself and Process
is per individual process. So the processor time of the processor would be usage on the PC. Processor time of a process would be the specified processes usage. For full description of category names: Performance Monitor Counters
An alternative to using the Performance Counter
Use System.Diagnostics.Process.TotalProcessorTime and System.Diagnostics.ProcessThread.TotalProcessorTime properties to calculate your processor usage as this article describes.

Combining the answers from ratty's and Haim's posts (including comments) I've come up with this, which for SQL Server seems to be the most elegant so far:
-- DROP TABLE #tmpTableSizes
CREATE TABLE #tmpTableSizes
(
tableName varchar(100),
numberofRows varchar(100),
reservedSize varchar(50),
dataSize varchar(50),
indexSize varchar(50),
unusedSize varchar(50)
)
insert #tmpTableSizes
EXEC sp_MSforeachtable @command1="EXEC sp_spaceused '?'"
select * from #tmpTableSizes
order by cast(LEFT(reservedSize, LEN(reservedSize) - 4) as int) desc
This gives you a list of all your tables in order of reserved size, ordered from largest to smallest.
If you're more comfortable working inside Excel/VBA, use the open event and test the environment: either have a signal file, a registry entry or an environment variable that controls what the open event does.
You can create the file/setting outside and test inside (use GetEnviromentVariable for env-vars) and test easily. I've written VBScript but the similarities to VBA cause me more angst than ease..

As I understand the problem, you want to use a spreadsheet normally most/some of the time yet have it run in batch and do something extra/different. You can open the sheet from the excel.exe command line but you can't control what it does unless it knows where it is. Using an environment variable is relatively simple and makes testing the spreadsheet easy.
To clarify, use the function below to examine the environment. In a module declare:
Private Declare Function GetEnvVar Lib "kernel32" Alias "GetEnvironmentVariableA" _
(ByVal lpName As String, ByVal lpBuffer As String, ByVal nSize As Long) As Long
Function GetEnvironmentVariable(var As String) As String
Dim numChars As Long
GetEnvironmentVariable = String(255, " ")
numChars = GetEnvVar(var, GetEnvironmentVariable, 255)
End Function
In the Workbook open event (as others):
Private Sub Workbook_Open()
If GetEnvironmentVariable("InBatch") = "TRUE" Then
Debug.Print "Batch"
Else
Debug.Print "Normal"
End If
End Sub
Add in active code as applicable. In the batch file, use
set InBatch=TRUE
You could do it like this:
iterations = 10
variables = 2
output <- matrix(ncol=variables, nrow=iterations)
for(i in 1:iterations){
output[i,] <- runif(2)
}
output
and then turn it into a data.frame
output <- data.frame(output)
class(output)
what this does:
The most important use case is probably exception checking.
While junit4 includes the expected element for checking if an exception occurred, it seems like it isn't part of the newer junit5. Another advantage of using fail()
over the expected
is that you can combine it with finally
allowing test-case cleanup.
dao.insert(obj);
try {
dao.insert(obj);
fail("No DuplicateKeyException thrown.");
} catch (DuplicateKeyException e) {
assertEquals("Error code doesn't match", 123, e.getErrorCode());
} finally {
//cleanup
dao.delete(obj);
}
As noted in another comment. Having a test to fail until you can finish implementing it sounds reasonable as well.
How about something like: Using HTML Agility Pack
HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(@"<html><body><p><table id=""foo""><tr><th>hello</th></tr><tr><td>world</td></tr></table></body></html>");
foreach (HtmlNode table in doc.DocumentNode.SelectNodes("//table")) {
Console.WriteLine("Found: " + table.Id);
foreach (HtmlNode row in table.SelectNodes("tr")) {
Console.WriteLine("row");
foreach (HtmlNode cell in row.SelectNodes("th|td")) {
Console.WriteLine("cell: " + cell.InnerText);
}
}
}
Note that you can make it prettier with LINQ-to-Objects if you want:
var query = from table in doc.DocumentNode.SelectNodes("//table").Cast<HtmlNode>()
from row in table.SelectNodes("tr").Cast<HtmlNode>()
from cell in row.SelectNodes("th|td").Cast<HtmlNode>()
select new {Table = table.Id, CellText = cell.InnerText};
foreach(var cell in query) {
Console.WriteLine("{0}: {1}", cell.Table, cell.CellText);
}
jQuery Library must be in the head section then.
<button onclick="var less = parseInt($('#qty').val()) - 1; $('#qty').val(less);"></button>
<input type="text" id="qty" value="2">
<button onclick="var add = parseInt($('#qty').val()) + 1; $('#qty').val(add);">+</button>
In my case I have a sequence called PS_LOG_SEQ
which had a LAST_NUMBER = 3920
.
I then imported some data from PROD
to my local machine and inserted into the PS_LOG
table. Production data had more than 20000
rows with the latest LOG_ID (primary key) being 20070. After importing I tried to insert new rows in this table but when saving I got an exception like this one:
ORA-00001: unique constraint (LOG.PS_LOG_PK) violated
Surely this has to do with the Sequence PS_LOG_SEQ
associated with the PS_LOG
table. The LAST_NUMBER
was colliding with data I imported which had already used the next ID value from the PS_LOG_SEQ
.
To solve that I used this command to update the sequence to the latest \ max(LOG_ID)
+ 1:
alter sequence PS_LOG_SEQ restart start with 20071;
This command reset the LAST_NUMBER
value and I could then insert new rows into the table. No more collision. :)
Note: this alter sequence
command is new in Oracle 12c.
Note: this blog post
documents the ALTER SEQUENCE RESTART option does exist, but as of 18c, is not documented. Its apparently intended for internal Oracle use.
Set Architectures to armv7 armv7s, Build Active Architecture Only to NO, for every target in the project, including every one in Pods
In my case, mismatch of version of two libraries.
I am using angular 7.0.0 and installed
"@swimlane/ngx-dnd": "^8.0.0"
and this caused the problem. Reverting this library to
"@swimlane/ngx-dnd": "6.0.0"
worked for me.
You could make use of expect (man expect comes with examples).
Mongoose Model
s inherit from Document
s, which have a toObject()
method. I believe what you're looking for should be the result of doc.toObject()
.
http://mongoosejs.com/docs/api.html#document_Document-toObject
Here is an example code that you may use:
$ STR="String;1;2;3"
$ for EACH in `echo "$STR" | grep -o -e "[^;]*"`; do
echo "Found: \"$EACH\"";
done
grep -o -e "[^;]*" will select anything that is not ';', therefore spliting the string by ';'.
Hope that help.
Simply use the graph API with this url format: https://graph.facebook.com/[email protected]&type=user&access_token=... You can easily create an application here and grab an access token for it here. I believe you get an estimated 600 requests per 600 seconds, although this isn't documented.
If you are doing this in bulk, you could use batch requests in batches of 20 email addresses. This may help with rate limits (I am not sure if you get 600 batch requests per 600 seconds or 600 individual requests).
I am currently working on a Linq-like library for Typescript and wanted to implement something like GetProperties of C# in Typescript / Javascript. The more I work with Typescript and generics, the clearer picture I get of that you usually have to have an instantiated object with intialized properties to get any useful information out at runtime about properties of a class. But it would be nice to retrieve information anyways just from the constructor function object, or an array of objects and be flexible about this.
Here is what I ended up with for now.
First off, I define Array prototype method ('extension method' for you C# developers).
export { } //creating a module of below code
declare global {
interface Array<T> {
GetProperties<T>(TClass: Function, sortProps: boolean): string[];
} }
The GetProperties method then looks like this, inspired by madreason's answer.
if (!Array.prototype.GetProperties) {
Array.prototype.GetProperties = function <T>(TClass: any = null, sortProps: boolean = false): string[] {
if (TClass === null || TClass === undefined) {
if (this === null || this === undefined || this.length === 0) {
return []; //not possible to find out more information - return empty array
}
}
// debugger
if (TClass !== null && TClass !== undefined) {
if (this !== null && this !== undefined) {
if (this.length > 0) {
let knownProps: string[] = Describer.describe(this[0]).Where(x => x !== null && x !== undefined);
if (sortProps && knownProps !== null && knownProps !== undefined) {
knownProps = knownProps.OrderBy(p => p);
}
return knownProps;
}
if (TClass !== null && TClass !== undefined) {
let knownProps: string[] = Describer.describe(TClass).Where(x => x !== null && x !== undefined);
if (sortProps && knownProps !== null && knownProps !== undefined) {
knownProps = knownProps.OrderBy(p => p);
}
return knownProps;
}
}
}
return []; //give up..
}
}
The describer method is about the same as madreason's answer. It can handle both class Function and if you get an object instead. It will then use Object.getOwnPropertyNames if no class Function is given (i.e. the class 'type' for C# developers).
class Describer {
private static FRegEx = new RegExp(/(?:this\.)(.+?(?= ))/g);
static describe(val: any, parent = false): string[] {
let isFunction = Object.prototype.toString.call(val) == '[object Function]';
if (isFunction) {
let result = [];
if (parent) {
var proto = Object.getPrototypeOf(val.prototype);
if (proto) {
result = result.concat(this.describe(proto.constructor, parent));
}
}
result = result.concat(val.toString().match(this.FRegEx));
result = result.Where(r => r !== null && r !== undefined);
return result;
}
else {
if (typeof val == "object") {
let knownProps: string[] = Object.getOwnPropertyNames(val);
return knownProps;
}
}
return val !== null ? [val.tostring()] : [];
}
}
Here you see two specs for testing this out with Jasmine.
class Hero {
name: string;
gender: string;
age: number;
constructor(name: string = "", gender: string = "", age: number = 0) {
this.name = name;
this.gender = gender;
this.age = age;
}
}
class HeroWithAbility extends Hero {
ability: string;
constructor(ability: string = "") {
super();
this.ability = ability;
}
}
describe('Array Extensions tests for TsExtensions Linq esque library', () => {
it('can retrieve props for a class items of an array', () => {
let heroes: Hero[] = [<Hero>{ name: "Han Solo", age: 44, gender: "M" }, <Hero>{ name: "Leia", age: 29, gender: "F" }, <Hero>{ name: "Luke", age: 24, gender: "M" }, <Hero>{ name: "Lando", age: 47, gender: "M" }];
let foundProps = heroes.GetProperties(Hero, false);
//debugger
let expectedArrayOfProps = ["name", "age", "gender"];
expect(foundProps).toEqual(expectedArrayOfProps);
expect(heroes.GetProperties(Hero, true)).toEqual(["age", "gender", "name"]);
});
it('can retrieve props for a class only knowing its function', () => {
let heroes: Hero[] = [];
let foundProps = heroes.GetProperties(Hero, false);
let expectedArrayOfProps = ["this.name", "this.gender", "this.age"];
expect(foundProps).toEqual(expectedArrayOfProps);
let foundPropsThroughClassFunction = heroes.GetProperties(Hero, true);
//debugger
expect(foundPropsThroughClassFunction.SequenceEqual(["this.age", "this.gender", "this.name"])).toBe(true);
});
And as madreason mentioned, you have to initialize the props to get any information out from just the class Function itself, or else it is stripped away when Typescript code is turned into Javascript code.
Typescript 3.7 is very good with Generics, but coming from a C# and Reflection background, some fundamental parts of Typescript and generics still feels somewhat loose and unfinished business. Like my code here, but at least I got out the information I wanted - a list of property names for a given class or instance of objects.
SequenceEqual is this method btw:
if (!Array.prototype.SequenceEqual) {
Array.prototype.SequenceEqual = function <T>(compareArray: T): boolean {
if (!Array.isArray(this) || !Array.isArray(compareArray) || this.length !== compareArray.length)
return false;
var arr1 = this.concat().sort();
var arr2 = compareArray.concat().sort();
for (var i = 0; i < arr1.length; i++) {
if (arr1[i] !== arr2[i])
return false;
}
return true;
}
}
you can try:
jQuery(this).get(0).tagName;
or
jQuery(this).get(0).nodeName;
note: replace this with your selector (h1, h3 or ...)
You can very well use Collections.synchronizedList(List) if all you need is simple invocation synchronization:
List<Object> objList = Collections.synchronizedList(new ArrayList<Object>());
Use jquery.ajaxchimp plugin to achieve that. It's dead easy!
<form method="post" action="YOUR_SUBSCRIBE_URL_HERE">
<input type="text" name="EMAIL" placeholder="e-mail address" />
<input type="submit" name="subscribe" value="subscribe!" />
<p class="result"></p>
</form>
JavaScript:
$(function() {
$('form').ajaxChimp({
callback: function(response) {
$('form .result').text(response.msg);
}
});
})
Please add this option:
//Boolean - Whether the scale should start at zero, or an order of magnitude down from the lowest value
scaleBeginAtZero : true,
(Reference: Chart.js)
N.B: The original solution I posted was for Highcharts, if you are not using Highcharts then please remove the tag to avoid confusion
Memcached is a newer API, it also provides memcached as a session provider which could be great if you have a farm of server.
After the version is still really low 0.2 but I have used both and I didn't encounter major problem, so I would go to memcached since it's new.

on shell works , sending to sdtout not , so that is one workaround, to write to stdout .
I made other approach, which is not run if sys.stdout.encoding is not define, or in others words , need export PYTHONIOENCODING=UTF-8 first to write to stdout.
import sys
if (sys.stdout.encoding is None):
print >> sys.stderr, "please set python env PYTHONIOENCODING=UTF-8, example: export PYTHONIOENCODING=UTF-8, when write to stdout."
exit(1)
so, using same example:
export PYTHONIOENCODING=UTF-8

will work
You won't face any terrible consequence, just the history will look kind of confusing.
You could change the commit message by doing
git commit --amend
git push --force-with-lease # (as opposed to --force, it doesn't overwrite others' work)
BUT this will override the remote history with yours, meaning that if anybody pulled that repo in the meanwhile, this person is going to be very mad at you...
Just do it if you are the only person accessing the repo.
Your "bad" output is UTF-8 displayed as CP1252.
On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:
df.to_csv('file.csv',encoding='utf-8-sig')
That encoder will add the BOM.
I see readytocloud.com is hosted on Apache 2.2.
There is a much simpler and more efficient way to redirect the non-www site to the www site in Apache.
Add the following rewrite rules to the Apache configs (either inside the virtual host or outside. It doesn't matter):
RewriteCond %{HTTP_HOST} ^readytocloud.com [NC]
RewriteRule ^/$ http://www.readytocloud.com/ [R=301,L]
Or, the following rewrite rules if you want a 1-to-1 mapping of URLs from the non-www site to the www site:
RewriteCond %{HTTP_HOST} ^readytocloud.com [NC]
RewriteRule (.*) http://www.readytocloud.com$1 [R=301,L]
Note, the mod_rewrite module needs to be loaded for this to work. Luckily readytocloud.com is runing on a CentOS box, which by default loads mod_rewrite.
We have a client server running Apache 2.2 with just under 3,000 domains and nearly 4,000 redirects, however, the load on the server hover around 0.10 - 0.20.
I'm using Studio 3.3.1 Build from Jan 28.
For me I was getting the "error android resource linking failed" pointing to a line in a layout file using ConstraintLayout that had been working correctly until today when the only change to my app level gradle file was to update the versions of:
android.arch.navigation:navigation-fragment
android.arch.navigation:navigation-ui
from 1.0.0-rc01
to 1.0.0-rc02
.
The error message said something about not recognizing layout_constraintTop_toTopOf
which of course is silly because it had been compiling quite happily for months.
I am already on 28.0.3 of build tools and compileSdkVersion
of 28. I've been using androidx.appcompat
everywhere for a while now (converted this project months back to androidx).
I first went through a project clean (no help), and invalidating cache/restart (no help). The layout in question had been originally defined using
<TextView>
, <EditText>
and <ImageView>
components (which had been working fine until today).
But after reading the above answers I thought maybe somehow there was confusion being caused here so I changed the layout to use:
<androidx.appcompat.widget
versions of all the various components. No change - still got the error.
I then deleted the <androidx.appcompat.widget.AppCompatTextView
block that was causing the compilation error. I changed all references to it in the other widgets to refer to "parent" instead. Did a Make. This time the compile completed without error.
So something strange in that widget definition I thought....here is what it was:
<androidx.appcompat.widget.AppCompatTextView
android:id="@+id/contact_firstname_label"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="@string/contact_fname_label"
android:gravity="end"
android:textAppearance="@android:style/TextAppearance.Material.Small"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toLeftOf="@+id/contact_detail_fname"
app:layout_constraintBaseline_toBaselineOf="@+id/contact_detail_fname"/>
I then pasted back the block I had Ctrl-V cut previously and changed the references back to that ID in the other components that reference it in the layout. Compile failed.
I cut the block again and pasted it to WordPad. Then reading from the WordPad paste, I actually typed it back in (i.e. I didn't copy/paste this time) - line by line, doing a make on the project after I typed in the minimal definition, and then again thereafter when I put in each new line. Each time the project compiled cleanly!
I don't know what to make of this. Perhaps some spurious invisible character was in the file originally?
static private Drawable **scaleDrawable**(Drawable drawable, int width, int height) {
int wi = drawable.getIntrinsicWidth();
int hi = drawable.getIntrinsicHeight();
int dimDiff = Math.abs(wi - width) - Math.abs(hi - height);
float scale = (dimDiff > 0) ? width / (float)wi : height /
(float)hi;
Rect bounds = new Rect(0, 0, (int)(scale * wi), (int)(scale * hi));
drawable.setBounds(bounds);
return drawable;
}

I didn't have time to read through them all but it seemed everyone was providing solutions to problems that shouldn't exist in the first place.
If you need all of the registered IService implementations then you need them all. But DO NOT inject them all with IEnumerable and then use logic to select one based on some type of key. Problem with doing that is you need a key and the logic should not need to change if the key changes ie; different implementation of IService so typeof doesn't work any more.
The Real Problem
There is business logic here that should be in an engine service. Something like IServiceDecisionEngine is needed. The implementation of the IServiceDecisionEngine gets ONLY the needed IService implementations from DI. Like
public class ServiceDecisionEngine<SomeData>: IServiceDecisionEngine<T>
{
public ServiceDecisionEngine(IService serviceA, IService serviceB) { }
public IService ResolveService(SomeData dataNeededForLogic)
{
if (dataNeededForLogic.someValue == true)
{
return serviceA;
}
return serviceB;
}
}
Now in your DI, you can do .AddScoped<IServiceDecisionEngine<SomeData>, new ServiceDecisionEngine(new ServiceA(), new ServiceB())
and the managerService that needs an IService will get it by injecting and using IServiceDecisionEngine.

WScript.exe
exists in two versions, one in C:\Windows\System32\
and the other in C:\Windows\SysWOW64\
directories. They run respectively in 64 bits and 32 bits (against immediate logic but true).
You may add the following code at the beginning of your script so that it automatically starts again in 32 bits if it detects that it's called in 64 bits.
Note that it transmits the arguments if it calls itself to switch to 64 bits.
' C:\Windows\System32\WScript.exe = WScript.exe
Dim ScriptHost : ScriptHost = Mid(WScript.FullName, InStrRev(WScript.FullName, "\") + 1, Len(WScript.FullName))
Dim oWs : Set oWs = CreateObject("WScript.Shell")
Dim oProcEnv : Set oProcEnv = oWs.Environment("Process")
' Am I running 64-bit version of WScript.exe/Cscript.exe? So, call script again in x86 script host and then exit.
If InStr(LCase(WScript.FullName), LCase(oProcEnv("windir") & "\System32\")) And oProcEnv("PROCESSOR_ARCHITECTURE") = "AMD64" Then
' rebuild arguments
If Not WScript.Arguments.Count = 0 Then
Dim sArg, Arg
sArg = ""
For Each Arg In Wscript.Arguments
sArg = sArg & " " & """" & Arg & """"
Next
End If
Dim sCmd : sCmd = """" & oProcEnv("windir") & "\SysWOW64\" & ScriptHost & """" & " """ & WScript.ScriptFullName & """" & sArg

In HTML, the <br/>
tag breaks the line. So, there's no sense to use an ASCII character for it.
In CSS we can use \A
for line break:
.selector::after{
content: '\A';
}
But if you want to display <br>
in the HTML as text then you can use:
<br> // < denotes to < sign and > denotes to > sign
It seems that with ASP.NET Core 2, you can again inherit AuthorizeAttribute
, you just need to also implement IAuthorizationFilter
(or IAsyncAuthorizationFilter
):
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = true, Inherited = true)]
public class CustomAuthorizeAttribute : AuthorizeAttribute, IAuthorizationFilter
{
private readonly string _someFilterParameter;
public CustomAuthorizeAttribute(string someFilterParameter)
{
_someFilterParameter = someFilterParameter;
}
public void OnAuthorization(AuthorizationFilterContext context)
{
var user = context.HttpContext.User;
if (!user.Identity.IsAuthenticated)
{
// it isn't needed to set unauthorized result
// as the base class already requires the user to be authenticated
// this also makes redirect to a login page work properly
// context.Result = new UnauthorizedResult();
return;
}
// you can also use registered services
var someService = context.HttpContext.RequestServices.GetService<ISomeService>();
var isAuthorized = someService.IsUserAuthorized(user.Identity.Name, _someFilterParameter);
if (!isAuthorized)
{
context.Result = new StatusCodeResult((int)System.Net.HttpStatusCode.Forbidden);
return;
}
}
}
Use the getWidth method in the following class:
import java.awt.*;
import java.awt.geom.*;
import java.awt.font.*;
class StringMetrics {
Font font;
FontRenderContext context;
public StringMetrics(Graphics2D g2) {
font = g2.getFont();
context = g2.getFontRenderContext();
}
Rectangle2D getBounds(String message) {
return font.getStringBounds(message, context);
}
double getWidth(String message) {
Rectangle2D bounds = getBounds(message);
return bounds.getWidth();
}
double getHeight(String message) {
Rectangle2D bounds = getBounds(message);
return bounds.getHeight();
}
}
Check the Namespace.
You might assign System.Web.Webpages.Html.SelectListItem in the Controller, instead of System.Web.Mvc.SelectListItem.

The problem in your initial definition of the class is that you've written:
class name(object, name):
This means that the class inherits the base class called "object", and the base class called "name". However, there is no base class called "name", so it fails. Instead, all you need to do is have the variable in the special init method, which will mean that the class takes it as a variable.
class name(object):
def __init__(self, name):
print name
If you wanted to use the variable in other methods that you define within the class, you can assign name to self.name, and use that in any other method in the class without needing to pass it to the method.
For example:
class name(object):
def __init__(self, name):
self.name = name
def PrintName(self):
print self.name
a = name('bob')
a.PrintName()
bob
For Kotlin:
Create two extensions, one for EditText and one for TextView
EditText:
fun EditText.clear() { text.clear() }
TextView:
fun TextView.clear() { text = "" }
and use it like
myEditText.clear()
myTextView.clear()
I ran into a similar problem because my master was set to " # of executor (The maximum number of concurrent builds that Jenkins may perform on this agent).
Go to Jenkins --> Manage Jenkins --> Manage Nodes, and click on the configure button of your master node (increase the number of executor to run mutiple jobs at a time).
HTTPS using Jersey client has two different version if you are using java 6 ,7 and 8 then
SSLContext sc = SSLContext.getInstance("SSL");
If using java 8 then
SSLContext sc = SSLContext.getInstance("TLSv1");
System.setProperty("https.protocols", "TLSv1");
Please find working code

Once you start running application will get Certificate error ,download certificate from browser and add into
C:\java-8\jdk1_8_0\jre\lib\security
Add into cacerts , you will get details in following links.
Few useful link to understand error

http://magicmonster.com/kb/prg/java/ssl/pkix_path_building_failed.html
I have tested following code for get and post method with SSL and basic Authentication here you can skip SSL Certificate , you can directly copy three class and add jar into java project and run.

I realize there is an accepted answer, and apparently it was either the size of memory chosen or the infinite loop suggestion that solved the issue for the OP.
For me, I added an array to the config file earlier and made some other changes prior to running artisan and getting the out of memory error and no amount of increasing memory helped. What it turned out to be was a missing comma after the array I added to the config file.
I am adding this answer in hopes that it helps someone else figure out what might be causing out of memory error. I am using laravel 5.4 under MAMP.
Use r.URL.Query()
when you appending to existing query, if you are building new set of params use the url.Values
struct like so
package main
import (
"fmt"
"log"
"net/http"
"net/url"
"os"
)
func main() {
req, err := http.NewRequest("GET","http://api.themoviedb.org/3/tv/popular", nil)
if err != nil {
log.Print(err)
os.Exit(1)
}
// if you appending to existing query this works fine
q := req.URL.Query()
q.Add("api_key", "key_from_environment_or_flag")
q.Add("another_thing", "foo & bar")
// or you can create new url.Values struct and encode that like so
q := url.Values{}
q.Add("api_key", "key_from_environment_or_flag")
q.Add("another_thing", "foo & bar")
req.URL.RawQuery = q.Encode()
fmt.Println(req.URL.String())
// Output:
// http://api.themoviedb.org/3/tv/popularanother_thing=foo+%26+bar&api_key=key_from_environment_or_flag
}

Hi i tried this it is working.
$("#change_align").css({"margin-top":"-39px","margin-right":"0px","margin-bottom":"0px","margin-left":"719px"});
Since sockstat wasn't natively installed on my machine I hacked up stanwise's answer to use netstat instead..
netstat -nlp | grep -E "[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\:2000" | awk '{print $7}' | sed -e "s/\/.*//g""
If you have error like "ERROR: could not open server file "/file": Permission denied" you can fix it that:
Ran through the same problem, and this is the solution I found: Create a new folder (for instance, tmp) under /home $ cd /home make postgres the owner of that folder $ chown -R postgres:postgres tmp copy in tmp the files you want to write into the database, and make sure they also are owned by postgres. That's it. You should be in business after that.
You can do it by using pymysql:
For example, let's suppose you have a MySQL database with the next user, password, host and port and you want to write in the database 'data_2', if it is already there or not.
import pymysql
user = 'root'
passw = 'my-secret-pw-for-mysql-12ud'
host = '172.17.0.2'
port = 3306
database = 'data_2'
If you already have the database created:
conn = pymysql.connect(host=host,
port=port,
user=user,
passwd=passw,
db=database,
charset='utf8')
data.to_sql(name=database, con=conn, if_exists = 'replace', index=False, flavor = 'mysql')
If you do NOT have the database created, also valid when the database is already there:
conn = pymysql.connect(host=host, port=port, user=user, passwd=passw)
conn.cursor().execute("CREATE DATABASE IF NOT EXISTS {0} ".format(database))
conn = pymysql.connect(host=host,
port=port,
user=user,
passwd=passw,
db=database,
charset='utf8')
data.to_sql(name=database, con=conn, if_exists = 'replace', index=False, flavor = 'mysql')
