It may happen after your Linux kernel update, if you entered this error, you can rebuild your nvidia driver using the following command to fix:
dkms
, which can automatically regenerate new modules after kernel version changes.sudo apt-get install dkms
/usr/src
.sudo dkms build -m nvidia -v 440.82
sudo dkms install -m nvidia -v 440.82
Now you can check to see if you can use it by sudo nvidia-smi
.
You should only access Linux files system (those located in lxss folder) from inside WSL; DO NOT create/modify any files in lxss folder in Windows - it's dangerous and WSL will not see these files.
Files can be shared between WSL and Windows, though; put the file outside of lxss folder. You can access them via drvFS (/mnt
) such as /mnt/c/Users/yourusername/files
within WSL. These files stay synced between WSL and Windows.
For details and why, see: https://blogs.msdn.microsoft.com/commandline/2016/11/17/do-not-change-linux-files-using-windows-apps-and-tools/
Building on the original tweet from @rustyshelf, and illustrated answer from iDevzilla, here's a solution that silences the noise from the simulator without disabling NSLog output from the device.
Do not log in as a root user, try another one with sudo permissions.
I followed these steps (for Mac).
In /etc/ssh/sshd_config
change
#ChallengeResponseAuthentication yes
#PasswordAuthentication yes
to
ChallengeResponseAuthentication no
PasswordAuthentication no
Now generate the RSA key:
ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa
(For me an RSA key worked. A DSA key did not work.)
A private key will be generated in ~/.ssh/id_rsa
along with ~/.ssh/id_rsa.pub
(public key).
Now move to the .ssh folder: cd ~/.ssh
Enter rm -rf authorized_keys
(sometimes multiple keys lead to an error).
Enter vi authorized_keys
Enter :wq
to save this empty file
Enter cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys
Restart the SSH:
sudo launchctl stop com.openssh.sshd
sudo launchctl start com.openssh.sshd
This might work for you:
sed 's|$ROOT|'"${HOME}"'|g' abc.sh > abc.sh.1
under ubuntu 12.04, eclipse juno. I face the same issue. This what I found on Yi Yu Blog
The solution is same as same as Leon
sudo -s
adb kill-server
adb start-server
adb devices
You should NOT run adb
server as root as other answers are suggesting. Instead if you are using Arch Linux do the following:
android-udev
package with PacmanReload udev rules:
# udevadm control --reload-rules
Add yourself to adbusers
group and then logout and login:
# usermod -aG adbusers $LOGNAME
Source: https://wiki.archlinux.org/index.php/android#Configuring_adb
Finally a solution that works without having to make any changes to the server:
Download the latest jsch.jar as Yvan suggests: http://sourceforge.net/projects/jsch/files/jsch.jar/ jsch-0.1.52.jar works fine
Place the downloaded file in your "...\JetBrains\PhpStorm 8.0.1\lib", and remove the existing jsch-file (for PHPStorm 8 it's jsch-0.1.50.jar)
Restart PHPStorm and it should work
Use the same solution for Webstorm
Inconsistent/duplicate module names in project structure was causing this issue for me.
File -> Project Strucutre -> Modules
This can happen when IntelliJ doesn't shut down properly and thus cannot properly save renamed module names.
Okay. I finally got to the bottom of this. You need to jump through some hoops to get the PUT and DELETE verbs working correctly with IIS8. In fact if you install the release candidate of VS 2012 and create a new WEB API project you'll find that the sample PUT and DELETE methods return 404 errors out of the box.
To use the PUT and DELETE verbs with the Web API you need to edit %userprofile%\documents\iisexpress\config\applicationhost.config and add the verbs to the ExtensionlessUrl handler as follows:
Change this line:
<add name="ExtensionlessUrl-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
to:
<add name="ExtensionlessUrl-Integrated-4.0" path="*." verb="GET,HEAD,POST,DEBUG,PUT,DELETE" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
In addition to the above you should ensure WebDAV is not interfering with your requests. This can be done by commenting out the following lines from applicationhost.config.
<add name="WebDAVModule" image="%IIS_BIN%\webdav.dll" />
<add name="WebDAVModule" />
<add name="WebDAV" path="*" verb="PROPFIND,PROPPATCH,MKCOL,PUT,COPY,DELETE,MOVE,LOCK,UNLOCK" modules="WebDAVModule" resourceType="Unspecified" requireAccess="None" />
Also be aware that the default Web API convention is that your method name should be the same as the invoked HTTP verb. For example if you're sending an HTTP delete request your method, by default, should be named Delete.
You can also use ES6 template literal concept to display the content of a JavaScript object in a string format.
alert(`${JSON.stringify(obj)}`);
const obj = {_x000D_
"name" : "John Doe",_x000D_
"habbits": "Nothing",_x000D_
};_x000D_
alert(`${JSON.stringify(obj)}`);
_x000D_
The above answer is totally true but not working for me.
I solved my problem with the following things.
Actually My XML is like that:
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/confirm_order_mail_layout"
android:layout_width="match_parent"
android:layout_height="fill_parent">
<android.support.design.widget.AppBarLayout
android:id="@+id/confirm_order_appbar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/confirm_order_list_collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:expandedTitleMarginEnd="64dp"
app:expandedTitleMarginStart="48dp"
app:layout_scrollFlags="scroll|enterAlways">
<android.support.v7.widget.Toolbar
android:id="@+id/confirm_order_toolbar_layout"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
I have tried all the option and after all I just removed CollapsingToolbarLayout
because of i do not need to use in that particular XML
So My Final XML is like:
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/confirm_order_mail_layout"
android:layout_width="match_parent"
android:layout_height="fill_parent">
<android.support.design.widget.AppBarLayout
android:id="@+id/confirm_order_appbar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="@+id/confirm_order_toolbar_layout"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>
Now you have to use setTitle()
like above answer:
mActionBarToolbar = (Toolbar) findViewById(R.id.confirm_order_toolbar_layout);
setSupportActionBar(mActionBarToolbar);
getSupportActionBar().setTitle("My Title");
Now If you want to use CollapsingToolbarLayout
and Toolbar
together then you have to use setTitle()
of CollapsingToolbarLayout
CollapsingToolbarLayout collapsingToolbarLayout = (CollapsingToolbarLayout) findViewById(R.id.confirm_order_mail_layout);
collapsingToolbarLayout.setTitle("My Title");
May it will helps you. Thank you.
The arguments can never be null
. They just wont exist.
In other words, what you need to do is check the length of your arguments.
public static void main(String[] args)
{
// Check how many arguments were passed in
if(args.length == 0)
{
System.out.println("Proper Usage is: java program filename");
System.exit(0);
}
}
Slightly related, I was looking for the unique combinations and I came up with this method:
def unique_columns(df,columns):
result = pd.Series(index = df.index)
groups = meta_data_csv.groupby(by = columns)
for name,group in groups:
is_unique = len(group) == 1
result.loc[group.index] = is_unique
assert not result.isnull().any()
return result
And if you only want to assert that all combinations are unique:
df1.set_index(['A','B']).index.is_unique
This one shows the user's uid as well as all the groups (with their gids) they belong to
id userid
You can do it in this way.
var somearray = ["20","40","80","400"];
somearray = somearray.map(Number);
var total = somearray.reduce(function(a,b){ return a+b },0)
console.log(total);
Half (but only half) snarky answer (the other half is bitter disdain of the reality of bureaucracy):
Use vh
Everything is always sized to browser window.
Always allow scroll down, but disable horizontal scroll.
Set body width to be a static 50vh, and never code css that floats or breaks out of the parent div. (If they try to mock up something that looks like it does, clever use of a background gif can throw them off track.) And style only using tables so everything is held rigidly into place as expected. Include a javascript function to undo any ctrl+/- activity the user may do.
Users will hate you, because the site doesn't flow differently based on what they're using (such as text being too small to read on phones). Your coworkers will hate you because nobody in their right mind does this and it will likely break their work (though not yours). Your programming professors will hate you because this is not a good idea. Your UX designer will hate you because it will reveal the corners they cut in designing UX mock-ups that they have to do in order to meet deadlines.
Nearly everyone will hate you, except the people who tell you to make things match the mock-up and to do so quickly. Those people, however (which generally include the project managers), will be ecstatic by your accuracy and fast turn around time. And everyone knows their opinion is the only one that matters to your paycheck.
You can use regular multiple expressions with the use of OR (|) operator.
function validateDate(date){
var regex=new RegExp("([0-9]{4}[-](0[1-9]|1[0-2])[-]([0-2]{1}[0-9]{1}|3[0-1]{1})|([0-2]{1}[0-9]{1}|3[0-1]{1})[-](0[1-9]|1[0-2])[-][0-9]{4})");
var dateOk=regex.test(date);
if(dateOk){
alert("Ok");
}else{
alert("not Ok");
}
}
Above function can validate YYYY-MM-DD, DD-MM-YYYY date formats. You can simply extend the regular expression to validate any date format. Assume you want to validate YYYY/MM/DD, just replace "[-]" with "[-|/]". This expression can validate dates to 31, months to 12. But leap years and months ends with 30 days are not validated.
In ubuntu, we can find all password related to keystore from the given path.
/home/user/.AndroidStudio2.2(current version)/system/log/idea.log.x(older versions)
edit the file and search android.injected.signing.store
, then you can find the passwords.
-Pandroid.injected.signing.store.file= path to your keystore
-Pandroid.injected.signing.store.password=yourstorepassword
-Pandroid.injected.signing.key.alias=yourkeyalias
-Pandroid.injected.signing.key.password=yourkeypassword
You could use d3py a python module that generate xml pages embedding d3.js script. For example :
import d3py
import networkx as nx
import logging
logging.basicConfig(level=logging.DEBUG)
G = nx.Graph()
G.add_edge(1,2)
G.add_edge(1,3)
G.add_edge(3,2)
G.add_edge(3,4)
G.add_edge(4,2)
# use 'with' if you are writing a script and want to serve this up forever
with d3py.NetworkXFigure(G, width=500, height=500) as p:
p += d3py.ForceLayout()
p.show()
On PostgreSQL you can use:
SELECT * FROM table_name WHERE (boolean_column IS NULL OR NOT boolean_column)
Short answer: in the Vault. Since Windows 7, a Vault was created for storing any sensitive data among it the credentials of Internet Explorer. The Vault is in fact a LocalSystem service - vaultsvc.dll.
Long answer: Internet Explorer allows two methods of credentials storage: web sites credentials (for example: your Facebook user and password) and autocomplete data. Since version 10, instead of using the Registry a new term was introduced: Windows Vault. Windows Vault is the default storage vault for the credential manager information.
You need to check which OS is running. If its Windows 8 or greater, you call VaultGetItemW8. If its isn't, you call VaultGetItemW7.
To use the "Vault", you load a DLL named "vaultcli.dll" and access its functions as needed.
A typical C++ code will be:
hVaultLib = LoadLibrary(L"vaultcli.dll");
if (hVaultLib != NULL)
{
pVaultEnumerateItems = (VaultEnumerateItems)GetProcAddress(hVaultLib, "VaultEnumerateItems");
pVaultEnumerateVaults = (VaultEnumerateVaults)GetProcAddress(hVaultLib, "VaultEnumerateVaults");
pVaultFree = (VaultFree)GetProcAddress(hVaultLib, "VaultFree");
pVaultGetItemW7 = (VaultGetItemW7)GetProcAddress(hVaultLib, "VaultGetItem");
pVaultGetItemW8 = (VaultGetItemW8)GetProcAddress(hVaultLib, "VaultGetItem");
pVaultOpenVault = (VaultOpenVault)GetProcAddress(hVaultLib, "VaultOpenVault");
pVaultCloseVault = (VaultCloseVault)GetProcAddress(hVaultLib, "VaultCloseVault");
bStatus = (pVaultEnumerateVaults != NULL)
&& (pVaultFree != NULL)
&& (pVaultGetItemW7 != NULL)
&& (pVaultGetItemW8 != NULL)
&& (pVaultOpenVault != NULL)
&& (pVaultCloseVault != NULL)
&& (pVaultEnumerateItems != NULL);
}
Then you enumerate all stored credentials by calling
VaultEnumerateVaults
Then you go over the results.
This example is using Lists: When clicking in some li it turn red
html:
<div id="app">
<ul>
<li @click="activate(li.id)" :class="{ active : active_el == li.id }" v-for="li in lista">{{li.texto}}</li>
</ul>
</div>
JS:
var app = new Vue({
el:"#app",
data:{
lista:[{"id":"1","texto":"line 1"},{"id":"2","texto":"line 2"},{"id":"3","texto":"line 3"},{"id":"4","texto":"line 4"},{"id":"5","texto":"line 5"}],
active_el:0
},
methods:{
activate:function(el){
this.active_el = el;
}
}
});
css
ul > li:hover {
cursor:pointer;
}
.active {
color:red;
font-weight:bold;
}
Fiddle:
What's this "other information"? An IP address?
In PHP, you use $_SERVER['REMOTE_ADDR']
to get the IP address of the remote client, then you can use gethostbyaddr()
to try and conver that IP into a hostname - but not all IPs have a reverse mapping configured.
One solution is to make your own params string.
This is the actual method I've been using for my latest project. You need to change args from hashtable to namevaluepair's:
private static String getPostParamString(Hashtable<String, String> params) {
if(params.size() == 0)
return "";
StringBuffer buf = new StringBuffer();
Enumeration<String> keys = params.keys();
while(keys.hasMoreElements()) {
buf.append(buf.length() == 0 ? "" : "&");
String key = keys.nextElement();
buf.append(key).append("=").append(params.get(key));
}
return buf.toString();
}
POSTing the params:
OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());
writer.write(getPostParamString(req.getPostParams()));
var time = 0;
var time_framerate = 1000; //in milliseconds
function animate(timestamp) {
if(timestamp > time + time_framerate) {
time = timestamp;
//your code
}
window.requestAnimationFrame(animate);
}
You could try changing Apache server to listen to some other port other than port 80.
Click on yellow WAMP icon in your taskbar Choose Apache -> httpd.conf Inside find these two lines of code:
Listen 80 ServerName localhost:80 and change them to something like this (they are not one next to the other):
Listen 8080 ServerName localhost:8080
OPTIONS tells you things such as "What methods are allowed for this resource".
HEAD gets the HTTP header you would get if you made a GET request, but without the body. This lets the client determine caching information, what content-type would be returned, what status code would be returned. The availability is only a small part of it.
Any Reference to 'Row' should use 'long' not 'integer' else it will overflow if the spreadsheet has a lot of data.
An array "decays" into a pointer to its first element, so scanf("%s", string)
is equivalent to scanf("%s", &string[0])
. On the other hand, scanf("%s", &string)
passes a pointer-to-char[256]
, but it points to the same place.
Then scanf
, when processing the tail of its argument list, will try to pull out a char *
. That's the Right Thing when you've passed in string
or &string[0]
, but when you've passed in &string
you're depending on something that the language standard doesn't guarantee, namely that the pointers &string
and &string[0]
-- pointers to objects of different types and sizes that start at the same place -- are represented the same way.
I don't believe I've ever encountered a system on which that doesn't work, and in practice you're probably safe. None the less, it's wrong, and it could fail on some platforms. (Hypothetical example: a "debugging" implementation that includes type information with every pointer. I think the C implementation on the Symbolics "Lisp Machines" did something like this.)
Hit this error trying to run terraform/terragrunt (Single go binary).
Using which terragrunt
to find where executable was, got strange error when running it in local dir or with full path
bash: ./terragrunt: No such file or directory
Problem was that there was two installations of terragrunt, used brew uninstall terragrunt
to remove one fixed it.
After removing the one, which terragrunt
showed the new path /usr/bin/terragrunt
everything worked fine.
I just tried it on another website, in firefox. After trying to save the webpage, it gave me a save-file-as dropdown menu with an option called webpage, svg only.
Additionally, if you want to use the filter in your controller the same way you do it here:
<div ng-repeat="item in items | filter:criteriaMatch(criteria)">
{{ item }}
</div>
You could do something like:
var filteredItems = $scope.$eval('items | filter:filter:criteriaMatch(criteria)');
I tried all the above with v 1.8.13 to no avail.
What worked for me (on macOS) was to use the doxywizard->Expert tag to fill the USE_MD_FILE_AS_MAINPAGE
setting.
It made the following changes to my Doxyfile:
USE_MDFILE_AS_MAINPAGE = ../README.md
...
INPUT = ../README.md \
../sdk/include \
../sdk/src
Note the line termination for INPUT
, I had just been using space as a separator as specified in the documentation. AFAICT this is the only change between the not-working and working version of the Doxyfile.
You can do this:
def deleteContent(pfile):
fn=pfile.name
pfile.close()
return open(fn,'w')
I can't say I know the best practice, but here's my perspective.
Are you using these variables for anything?
Personally, I haven't needed to change neither, on Linux nor Windows, in environments varying from development to production. Unless you are doing something particular that relies on them, chances are you could leave them alone.
catalina.sh
sets the variables that Tomcat needs to work out of the box. It also says that CATALINA_BASE
is optional:
# CATALINA_HOME May point at your Catalina "build" directory.
#
# CATALINA_BASE (Optional) Base directory for resolving dynamic portions
# of a Catalina installation. If not present, resolves to
# the same directory that CATALINA_HOME points to.
I'm pretty sure you'll find out whether or not your setup works when you start your server.
We just released an experimental GitHub repository which should ease the process of using NVIDIA GPUs inside Docker containers.
The easiest way is to set some variable in the file that calls include, such as
$including = true;
Then in the file that's being included, check for the variable
if (!$including) exit("direct access not permitted");
I'll explain it in a simple way.
Generics defined at Class level are completely separate from the generics defined at the (static) method level.
class Greet<T> {
public static <T> void sayHello(T obj) {
System.out.println("Hello " + obj);
}
}
When you see the above code anywhere, please note that the T defined at the class level has nothing to do with the T defined in the static method. The following code is also completely valid and equivalent to the above code.
class Greet<T> {
public static <E> void sayHello(E obj) {
System.out.println("Hello " + obj);
}
}
Why the static method needs to have its own generics separate from those of the Class?
This is because, the static method can be called without even instantiating the Class. So if the Class is not yet instantiated, we do not yet know what is T. This is the reason why the static methods needs to have its own generics.
So, whenever you are calling the static method,
Greet.sayHello("Bob");
Greet.sayHello(123);
JVM interprets it as the following.
Greet.<String>sayHello("Bob");
Greet.<Integer>sayHello(123);
Both giving the same outputs.
Hello Bob
Hello 123
It's simple with open source 7zip SFX-Packager - easy way to just "Drag & drop" folders onto it, and it creates a portable/self-extracting package.
Simplest solution: You're probably running out of virtual address space (any other form of error usually means running really slowly for a long time before you finally get a MemoryError
). This is because a 32 bit application on Windows (and most OSes) is limited to 2 GB of user mode address space (Windows can be tweaked to make it 3 GB, but that's still a low cap). You've got 8 GB of RAM, but your program can't use (at least) 3/4 of it. Python has a fair amount of per-object overhead (object header, allocation alignment, etc.), odds are the strings alone are using close to a GB of RAM, and that's before you deal with the overhead of the dictionary, the rest of your program, the rest of Python, etc. If memory space fragments enough, and the dictionary needs to grow, it may not have enough contiguous space to reallocate, and you'll get a MemoryError
.
Install a 64 bit version of Python (if you can, I'd recommend upgrading to Python 3 for other reasons); it will use more memory, but then, it will have access to a lot more memory space (and more physical RAM as well).
If that's not enough, consider converting to a sqlite3
database (or some other DB), so it naturally spills to disk when the data gets too large for main memory, while still having fairly efficient lookup.
If, at some point, you only need to export a single result set, just right click "on the data" (any column of any row) there you will find an export option. The wizard exports the complete result set regardless of what you selected
To make sure you have the application's path (and not just the current directory), use this:
http://msdn.microsoft.com/en-us/library/system.diagnostics.process.getcurrentprocess.aspx
Now you have a Process
object that represents the process that is running.
Then use Process.MainModule.FileName
:
http://msdn.microsoft.com/en-us/library/system.diagnostics.processmodule.filename.aspx
Finally, use Path.GetDirectoryName
to get the folder containing the .exe:
http://msdn.microsoft.com/en-us/library/system.io.path.getdirectoryname.aspx
So this is what you want:
string folder = Path.GetDirectoryName(Process.GetCurrentProcess().MainModule.FileName) + @"\Archive\";
string filter = "*.zip";
string[] files = Directory.GetFiles(folder, filter);
(Notice that "\Archive\"
from your question is now @"\Archive\"
: you need the @ so that the \
backslashes aren't interpreted as the start of an escape sequence)
Hope that helps!
There are many errors in your code, for example you are not really calling your deck by just typing deck
in your Shuffle
method. You can only call it by typing theCard.deck
I have changed your shuffle method:
public void Shuffle(){
for (int i = 0; i < theCard.deck.length; i++) {
int index = (int)(Math.random()*theCard.deck.length );
int temp = theCard.deck[i];
theCard.deck[i] = theCard.deck[index];
theCard.deck[index] = temp;
remainingCards--;
}
}
Also, as it is said you have structural problem. You should name classes as you understand in real life, for example, when you say card, it is only one card, when you say deck it is supposed to be 52+2 cards. In this way your code would be more understandable.
If you want to rename a single column and keep the rest as it is:
from pyspark.sql.functions import col
new_df = old_df.select(*[col(s).alias(new_name) if s == column_to_change else s for s in old_df.columns])
Created a .r file and saved it in Desktop together with a sample_10000.csv file.
Once trying to read it
heisenberg <- read.csv(file="sample_100000.csv")
was getting the same error as you
heisenberg <- read.csv(file="sample_10000") Error in file(file, "rt") : cannot open the connection In addition: Warning message: In file(file, "rt") : cannot open file 'sample_10000': No such file or directory
I knew at least two ways to fix this, one using the absolute path and the other changing the working directory.
I fixed it adding the absolute path to the file, more precisely
heisenberg <- read.csv(file="C:/Users/tiago/Desktop/sample_100000.csv")
This error shows up because RStudio has a specific working directory defined which isn't necessarily the place the .r file is at.
So, to fix using this approach I've gone to Session > Set Working Directory > Chose Directory (CTRL + Shift + H) and selected Desktop, where the .csv file was at. That way running the following command also worked
heisenberg <- read.csv(file="sample_100000.csv")
The answer by retracile should be the closest one, yet it does not work for my case. One insert query just broke in the middle and the export just stopped. Not sure what is the reason. However It works fine during .dump
.
Finally I wrote a tool for the split up the SQL generated from .dump
:
You have to create custom pipe.
import { Injectable, Pipe } from '@angular/core';
@Pipe({
name: 'keyobject'
})
@Injectable()
export class Keyobject {
transform(value, args:string[]):any {
let keys = [];
for (let key in value) {
keys.push({key: key, value: value[key]});
}
return keys;
}}
And then use it in your *ngFor
*ngFor="let item of data | keyobject"
PHP manual has a good read on the question here.
The visibility of a property or method can be defined by prefixing the declaration with the keywords public, protected or private. Class members declared public can be accessed everywhere. Members declared protected can be accessed only within the class itself and by inherited and parent classes. Members declared as private may only be accessed by the class that defines the member.
You should put the form inside each node and use ng-show
and ng-hide
to enable and disable editing, respectively. Something like this:
<li>
<span ng-hide="editing" ng-click="editing = true">{{bday.name}} | {{bday.date}}</span>
<form ng-show="editing" ng-submit="editing = false">
<label>Name:</label>
<input type="text" ng-model="bday.name" placeholder="Name" ng-required/>
<label>Date:</label>
<input type="date" ng-model="bday.date" placeholder="Date" ng-required/>
<br/>
<button class="btn" type="submit">Save</button>
</form>
</li>
The key points here are:
ng-model
to the local scopeng-show
to form
so we can show it while editingspan
with a ng-hide
to hide the content while editingng-click
, that could be in any other element, that toggles editing
to true
ng-submit
to toggle editing

Here is your updated Plunker.
Disclaimer: this is an update to Cascabel's answer, which I'm writing to save the curious some time.
I tried in vain to replicate (in Git 2.0.1) the remote HEAD is ambiguous
message that Cascabel mentions in his answer; so I did a bit of digging (by cloning https://github.com/git/git and searching the log). It used to be that
Determining HEAD is ambiguous since it is done by comparing SHA1s. In the case of multiple matches we return refs/heads/master if it matches, else we return the first match we encounter. builtin-remote needs all matches returned to it, so add a flag for it to request such.
(Commit 4229f1fa325870d6b24fe2a4c7d2ed5f14c6f771
, dated Feb 27, 2009, found with git log --reverse --grep="HEAD is ambiguous"
)
However, the ambiguity in question has since been lifted:
One long-standing flaw in the pack transfer protocol used by "git clone" was that there was no way to tell the other end which branch "HEAD" points at, and the receiving end needed to guess. A new capability has been defined in the pack protocol to convey this information so that cloning from a repository with more than one branches pointing at the same commit where the HEAD is at now reliably sets the initial branch in the resulting repository.
(Commit 9196a2f8bd46d36a285bdfa03b4540ed3f01f671
, dated Nov 8, 2013, found with git log --grep="ambiguous" --grep="HEAD" --all-match
)
Edit (thanks to torek):
$ git name-rev --name-only 9196a2f8bd46d36a285bdfa03b4540ed3f01f671

This means that, if you're using Git v1.8.4.3 or later, you shouldn't run into any ambiguous-remote-HEAD problem.
Actually, .size()
is not pure JavaScript method, there is a accessor property .size
of Set object that is a little looks like .size()
but it is not a function method, just as I said, it is an accessor property of a Set object to show the unique number of (unique) elements in a Set object.
The size accessor property returns the number of (unique) elements in a Set object.
const set1 = new Set();
const object1 = new Object();
set1.add(42);
set1.add('forty two');
set1.add('forty two');
set1.add(object1);
console.log(set1.size);
// expected output: 3
And length
is a property of an iterable object(array) that returns the number of elements in that array. The value is an unsigned, 32-bit integer that is always numerically greater than the highest index in the array.
const clothing = ['shoes', 'shirts', 'socks', 'sweaters'];
console.log(clothing.length);
// expected output: 4
If you are using Visual Studio. The reason you might be recieving this error may be because you originally created a new header file.h and then renamed it to file.cpp where you placed your main() function.
To fix the issue right click file.cpp -> click Properties
go to
Configuration Properties -> General ->Item Type and change its value to
C/C++ compiler instead of C/C++ header.
The accepted answer makes you believe that you must use a class or a std::function
as comparator. This is not true! As cute_ptr's answer shows, you can pass a function pointer to the constructor. However, the syntax to do so is much simpler than shown there:
class Node;
bool Compare(Node a, Node b);
std::priority_queue<Node, std::vector<Node>, decltype(&Compare)> openSet(Compare);
That is, there is no need to explicitly encode the function's type, you can let the compiler do that for you using decltype
.
This is very useful if the comparator is a lambda. You cannot specify the type of a lambda in any other way than using decltype
. For example:
auto compare = [](Node a, Node b) { return a.foo < b.foo; }
std::priority_queue<Node, std::vector<Node>, decltype(compare)> openSet(compare);
None of the answers here satisfies my needs.
The answer from Muno is wrong because it lists ONLY the USB ports.
The answer from code4life is wrong because it lists all EXCEPT the USB ports. (Nevertheless it has 44 up-votes!!!)
I have an EPSON printer simulation port on my computer which is not listed by any of the answers here. So I had to write my own solution. Additionally I want to display more information than just the caption string. I also need to separate the port name from the description.
My code has been tested on Windows XP, Windows 7 and Windows 10.
The Port Name (like "COM1") must be read from the registry because WMI does not give this information for all COM ports (EPSON).
If you use my code you do not need SerialPort.GetPortNames()
anymore. My function returns the same ports, but with additional details. Why did Microsoft not implement such a function into the framework??
using System.Management;
using Microsoft.Win32;
using (ManagementClass i_Entity = new ManagementClass("Win32_PnPEntity"))
{
foreach (ManagementObject i_Inst in i_Entity.GetInstances())
{
Object o_Guid = i_Inst.GetPropertyValue("ClassGuid");
if (o_Guid == null || o_Guid.ToString().ToUpper() != "{4D36E978-E325-11CE-BFC1-08002BE10318}")
continue; // Skip all devices except device class "PORTS"
String s_Caption = i_Inst.GetPropertyValue("Caption") .ToString();
String s_Manufact = i_Inst.GetPropertyValue("Manufacturer").ToString();
String s_DeviceID = i_Inst.GetPropertyValue("PnpDeviceID") .ToString();
String s_RegPath = "HKEY_LOCAL_MACHINE\\System\\CurrentControlSet\\Enum\\" + s_DeviceID + "\\Device Parameters";
String s_PortName = Registry.GetValue(s_RegPath, "PortName", "").ToString();
int s32_Pos = s_Caption.IndexOf(" (COM");
if (s32_Pos > 0) // remove COM port from description
s_Caption = s_Caption.Substring(0, s32_Pos);
Console.WriteLine("Port Name: " + s_PortName);
Console.WriteLine("Description: " + s_Caption);
Console.WriteLine("Manufacturer: " + s_Manufact);
Console.WriteLine("Device ID: " + s_DeviceID);
Console.WriteLine("-----------------------------------");
}
}

You can also create a search pipe to filter results:
import { Pipe, PipeTransform } from '@angular/core';
@Pipe({
name : 'searchPipe',
})
export class SearchPipe implements PipeTransform {
public transform(value, key: string, term: string) {
return value.filter((item) => {
if (item.hasOwnProperty(key)) {
if (term) {
let regExp = new RegExp('\\b' + term, 'gi');
return regExp.test(item[key]);
} else {
return true;
}
} else {
return false;
}
});
}
}
Use pipe in HTML :
<md-input placeholder="Item name..." [(ngModel)]="search" ></md-input>
<div *ngFor="let item of items | searchPipe:'name':search ">
{{item.name}}
</div>
how do you get
"\u6f22\u5b57"
from??
in JavaScript?
These are JavaScript Unicode escape sequences e.g. \u12AB
. To convert them, you could iterate over every code unit in the string, call .toString(16)
on it, and go from there.
However, it is more efficient to also use hexadecimal escape sequences e.g. \xAA
in the output wherever possible.
Also note that ASCII symbols such as A
, b
, and -
probably don’t need to be escaped.
I’ve written a small JavaScript library that does all this for you, called jsesc
. It has lots of options to control the output.
Here’s an online demo of the tool in action: http://mothereff.in/js-escapes#1%E6%BC%A2%E5%AD%97
Your question was tagged as utf-8
. Reading the rest of your question, UTF-8 encoding/decoding didn’t seem to be what you wanted here, but in case you ever need it: use utf8.js
(online demo).
%W
and %w
allow you to create an Array of strings without using quotes and commas.
POSIX 7 on echo
http://pubs.opengroup.org/onlinepubs/9699919799/utilities/echo.html
-e
is not defined and backslashes are implementation defined:
If the first operand is -n, or if any of the operands contain a <backslash> character, the results are implementation-defined.
unless you have an optional XSI extension.
So I recommend that you should use printf
instead, which is well specified:
format operand shall be used as the format string described in XBD File Format Notation [...]
the File Format Notation:
\n <newline> Move the printing position to the start of the next line.
Also keep in mind that Ubuntu 15.10 and most distros implement echo
both as:
help echo
which echo
which can lead to some confusion.

In my opinion the best solutions is in this link: http://www.myonlinetraininghub.com/excel-factor-12-secret-evaluate-function
Here is a summary: 1) In cell A1 enter 1, 2) In cell A2 enter 2, 3) In cell A3 enter +, 4) Create a named range, with "=Evaluate(A1 & A3 & A2)" in the refers to field while creating the named range. Lets call this named range "testEval", 5) In cell A4 enter =testEval,
Cell A4 should have the value 3 in it.
Notes: a) Requires no programming/vba. b) I did this in Excel 2013 and it works.
Granted you have administrative Windows privileges on the server, another option would be to start SQL Server in Single User Mode, using the Startup parameter "-m". Doing this, you can login using SQLCMD, create a new user and give it sysadmin privileges. Finally, you have to disable Single User Mode, login to SSMS using your new user, and go to Segurity/Logins and change "sa" user password.
You can check this post: http://v-consult.be/2011/05/26/recover-sa-password-microsoft-sql-server-2008-r2/
The easiest way to get a new list would be:
List<long> unique = longs.Distinct().ToList();
Is that good enough for you, or do you need to mutate the existing list? The latter is significantly more long-winded.
Note that Distinct()
isn't guaranteed to preserve the original order, but in the current implementation it will - and that's the most natural implementation. See my Edulinq blog post about Distinct()
for more information.
If you don't need it to be a List<long>
, you could just keep it as:
IEnumerable<long> unique = longs.Distinct();
At this point it will go through the de-duping each time you iterate over unique
though. Whether that's good or not will depend on your requirements.
If you set the domain for the php session cookie, browsers seem to hold on to it for 30 seconds or so. It doesn't seem to matter if you close the tab or browser window.
So if you are managing sessions using something like the following it may be causing the cookie to hang in the browser for longer than expected.
ini_set("session.cookie_domain", 'www.domain.com');
The only way I've found to get rid of the hanging cookie is to remove the line of code that sets the session cookie's domain. Also watch out for session_set_cookie_params() function. Dot prefixing the domain seems to have no bearing on the issue either.
This might be a php bug as php sends a session cookie (i.e. PHPSESSID=b855ed53d007a42a1d0d798d958e42c9
) in the header after the session has been destroyed. Or it might be a server propagation issue but I don't thinks so since my test were on a private servers.
Take IISReset as a suite of commands that helps you manage IIS start / stop etc.
Which means you need to specify option (/switch
) what you want to do to carry any operation.
Default behavior OR default switch is /restart
with iisreset
so you do not need to run command twice with /start
and /stop
.
Hope this clarifies your question. For reference the output of iisreset /?
is:
IISRESET.EXE (c) Microsoft Corp. 1998-2005 Usage: iisreset [computername] /RESTART Stop and then restart all Internet services. /START Start all Internet services. /STOP Stop all Internet services. /REBOOT Reboot the computer. /REBOOTONERROR Reboot the computer if an error occurs when starting, stopping, or restarting Internet services. /NOFORCE Do not forcefully terminate Internet services if attempting to stop them gracefully fails. /TIMEOUT:val Specify the timeout value ( in seconds ) to wait for a successful stop of Internet services. On expiration of this timeout the computer can be rebooted if the /REBOOTONERROR parameter is specified. The default value is 20s for restart, 60s for stop, and 0s for reboot. /STATUS Display the status of all Internet services. /ENABLE Enable restarting of Internet Services on the local system. /DISABLE Disable restarting of Internet Services on the local system.
When deciding whether to make a class static or non-static you need to look at what information you are trying to represent. This entails a more 'bottom-up' style of programming where you focus on the data you are representing first. Is the class you are writing a real-world object like a rock, or a chair? These things are physical and have physical attributes such as color, weight which tells you that you may want to instantiate multiple objects with different properties. I may want a black chair AND a red chair at the same time. If you ever need two configurations at the same time then you instantly know you will want to instantiate it as an object so each object can be unique and exist at the same time.
On the other end, static functions tend to lend more to actions which do not belong to a real-world object or an object that you can easily represent. Remember that C#'s predecessors are C++ and C where you can just define global functions that do not exist in a class. This lends more to 'top-down' programming. Static methods can be used for these cases where it doesn't make sense that an 'object' performs the task. By forcing you to use classes this just makes it easier to group related functionality which helps you create more maintainable code.
Most classes can be represented by either static or non-static, but when you are in doubt just go back to your OOP roots and try to think about what you are representing. Is this an object that is performing an action (a car that can speed up, slow down, turn) or something more abstract (like displaying output).
Get in touch with your inner OOP and you can never go wrong!
Why nobody mentions matchMedia?

Did not test that much, but tested with android default and android chrome browsers, desktop chrome, so far it looks like it works well.
Of course it does not return number value, but returns boolean - if matches or not, so might not exactly fit the question but that's what we want anyway and probably the author of question wants.
In standard Markdown, place an anchor <a name="abcd"></a>
where you want to link to and refer to it on the same page by [link text](#abcd)
.
(This uses name=
and not id=
, for reasons explained in this answer.)
Remote references can use [link text](http://...#abcd)
of course.
This works like a dream, provided you have control over the source and target texts. The anchor can even appear in a heading, thus:
### <a name="head1234"></a>A Heading in this SO entry!
produces:
and we can even link to it so:
and we can even [link](#head1234) to it so:
(On SO, the link doesn't work because the anchor is stripped.)
You need to have at least the same number of columns and each column has to be defined in exactly the same way, i.e. a varchar column can't be inserted into an int column.
For bulk transfer, check the documentation for the SQL implementation you're using. There are often tools available to bulk transfer data from one table to another. For SqlServer 2005, for example, you could use the SQL Server Import and Export Wizard. Right-click on the database you're trying to move data around in and click Export to access it.
Angular CLI: 8.3.1
when you have multiple module.ts
files inside a module, you need to specify for which module file you are generating component.
ng g c modulefolder/componentname --module=modulename.module
for e.g. i have shared module folder inside which i have shared.module.ts
and material.module.ts
like this
shared
> shared.module.ts
> material.module.ts
and i want to generate sidebar
component for shared.module.ts
then i will run following command
ng g c shared/sidebar --module=shared.module
if you want to export the component then run following command
ng g c shared/sidebar --module=shared.module --export
I don't know anything about jquery so can't help you with that, but as far as Javascript is concerned you have an array of objects, so what you will only be able to access the names & values through each array element. E.g arr[0].name
will give you 'k1'
, arr[1].value
will give you 'hi'
.
Maybe you want to do something like:
var obj = {};
obj.k1 = "abc";
obj.k2 = "hi";
obj.k3 = "oa";
alert ("obj.k2:" + obj.k2);
The 'more than 100% width' on the table really made it work for me.

It seems you are hitting a UTF-8 byte order mark (BOM). Try using this unicode string with BOM extracted out:
import codecs
content = unicode(q.content.strip(codecs.BOM_UTF8), 'utf-8')
parser.parse(StringIO.StringIO(content))
I used strip
instead of lstrip
because in your case you had multiple occurences of BOM, possibly due to concatenated file contents.
For more complex type validations I like typeguard's approach of validating based on python type hint annotations:
from typeguard import check_type
from typing import List
try:
check_type('mylist', [1, 2], List[int])
except TypeError as e:
print(e)
You can perform very complex validations in very clean and readable fashion.
check_type('foo', [1, 3.14], List[Union[int, float]])
# vs
isinstance(foo, list) and all(isinstance(a, (int, float)) for a in foo)
I have also tried some things using the asynchronous methods in python, how ever I have had much better luck using twisted for asynchronous programming. It has fewer problems and is well documented. Here is a link of something simmilar to what you are trying in twisted.
http://pythonquirks.blogspot.com/2011/04/twisted-asynchronous-http-request.html
If you are mocking the behavior (with something like doNothing()
) there should really be no need to call to verify*()
. That said, here's my stab at re-writing your test method:
@PrepareForTest({InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest { //Note the renaming of the test class.
public void testProcessOrder() {
//Variables
InternalService is = new InternalService();
Order order = mock(Order.class);
//Mock Behavior
when(order.isSuccessful()).thenReturn(true);
mockStatic(Internalutils.class);
doNothing().when(InternalUtils.class); //This is the preferred way
//to mock static void methods.
InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());
//Execute
is.processOrder(order);
//Verify
verifyStatic(InternalUtils.class); //Similar to how you mock static methods
//this is how you verify them.
InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());
}
}
I grouped into four sections to better highlight what is going on:
I choose to declare any instance variables / method arguments / mock collaborators here. If it is something used in multiple tests, consider making it an instance variable of the test class.
This is where you define the behavior of all of your mocks. You're setting up return values and expectations here, prior to executing the code under test. Generally speaking, if you set the mock behavior here you wouldn't need to verify the behavior later.
Nothing fancy here; this just kicks off the code being tested. I like to give it its own section to call attention to it.
This is when you call any method starting with verify
or assert
. After the test is over, you check that the things you wanted to have happen actually did happen. That is the biggest mistake I see with your test method; you attempted to verify the method call before it was ever given a chance to run. Second to that is you never specified which static method you wanted to verify.
This is mostly personal preference on my part. There is a certain order you need to do things in but within each grouping there is a little wiggle room. This helps me quickly separate out what is happening where.
I also highly recommend going through the examples at the following sites as they are very robust and can help with the majority of the cases you'll need:
You can use something like:
<beans>
<bean id="myBean" class="..." init-method="init"/>
</beans>
This will call the "init" method when the bean is instantiated.
From my point of view this error "Error: Aesthetics must either be length one, or the same length as the data" refers to the argument aes(x,y) I tried the na.omit() and worked just fine to me.
ArrayList
already have support for this, with the equals
method. Quoting the docs
... In other words, two lists are defined to be equal if they contain the same elements in the same order.
It does require you to properly implement equals
in your MyData
class.
Edit
You have updated the question stating that the lists could have different orders. In that case, sort your list first, and then apply equals.
If the variable is a parameter then you could use advanced function parameter binding like below to validate not null or empty:
[CmdletBinding()]
Param (
[parameter(mandatory=$true)]
[ValidateNotNullOrEmpty()]
[string]$Version
)
select distinct a.FirstName, a.LastName, v.District from AddTbl a inner join ValTbl v on a.LastName = v.LastName order by a.FirstName;
hope this helps
Use the exec() method. For example, say you have a dictionary and you want to turn each key into a variable with its original dictionary value can do the following.
Python 2
>>> c = {"one": 1, "two": 2}
>>> for k,v in c.iteritems():
... exec("%s=%s" % (k,v))
>>> one
1
>>> two
2
Python 3
>>> c = {"one": 1, "two": 2}
>>> for k,v in c.items():
... exec("%s=%s" % (k,v))
>>> one
1
>>> two
2
check the above image(static directory) for dir structure
const publicDirectoryPath = path.join(__dirname,'../public')

res.sendFile(path.join(publicDirectoryPath,'index.html'))
Use regex pattern ^(?=.{8})(?=.*[^a-zA-Z])
Explanation:
^(?=.{8})(?=.*[^a-zA-Z])
¦+------++-------------+
¦ ¦ ¦
¦ ¦ + string contains some non-letter character
¦ ¦
¦ + string contains at least 8 characters
¦
+ begining of line/string
If you want to limit also maximum length (let's say 16), then use regex pattern:
^(?=.{8,16}$)(?=.*[^a-zA-Z])
You can use Windows Containers inside a virtual machine (the guest OS should match the requirements - Windows 10 Pro or Windows 2016).
For example you can use VirtualBox, just enable Hyper-V inside System / Acceleration / Paravirtualization Interface.
After that if Docker doesn't start up because of an error, use the "Switch to Windows containers..." in the settings.
(this could be moved as a comment to the accepted answer, but I don't have enough reputation to do so)
Use this query,
alter table `table_name` add primary key(`column_name`);

works just fine.
Note: this post assumes Python 3.x syntax.†
A generator is simply a function which returns an object on which you can call next
, such that for every call it returns some value, until it raises a StopIteration
exception, signaling that all values have been generated. Such an object is called an iterator.
Normal functions return a single value using return
, just like in Java. In Python, however, there is an alternative, called yield
. Using yield
anywhere in a function makes it a generator. Observe this code:
>>> def myGen(n):
... yield n
... yield n + 1
...
>>> g = myGen(6)
>>> next(g)
6
>>> next(g)
7
>>> next(g)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
StopIteration
As you can see, myGen(n)
is a function which yields n
and n + 1
. Every call to next
yields a single value, until all values have been yielded. for
loops call next
in the background, thus:
>>> for n in myGen(6):
... print(n)
...
6
7
Likewise there are generator expressions, which provide a means to succinctly describe certain common types of generators:
>>> g = (n for n in range(3, 5))
>>> next(g)
3
>>> next(g)
4
>>> next(g)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
StopIteration
Note that generator expressions are much like list comprehensions:
>>> lc = [n for n in range(3, 5)]
>>> lc
[3, 4]
Observe that a generator object is generated once, but its code is not run all at once. Only calls to next
actually execute (part of) the code. Execution of the code in a generator stops once a yield
statement has been reached, upon which it returns a value. The next call to next
then causes execution to continue in the state in which the generator was left after the last yield
. This is a fundamental difference with regular functions: those always start execution at the "top" and discard their state upon returning a value.
There are more things to be said about this subject. It is e.g. possible to send
data back into a generator (reference). But that is something I suggest you do not look into until you understand the basic concept of a generator.
Now you may ask: why use generators? There are a couple of good reasons:
Generators allow for a natural way to describe infinite streams. Consider for example the Fibonacci numbers:
>>> def fib():
... a, b = 0, 1
... while True:
... yield a
... a, b = b, a + b
...
>>> import itertools
>>> list(itertools.islice(fib(), 10))
[0, 1, 1, 2, 3, 5, 8, 13, 21, 34]
This code uses itertools.islice
to take a finite number of elements from an infinite stream. You are advised to have a good look at the functions in the itertools
module, as they are essential tools for writing advanced generators with great ease.
† About Python <=2.6: in the above examples next
is a function which calls the method __next__
on the given object. In Python <=2.6 one uses a slightly different technique, namely o.next()
instead of next(o)
. Python 2.7 has next()
call .next
so you need not use the following in 2.7:
>>> g = (n for n in range(3, 5))
>>> g.next()
3
Different browsers do this differently.
First open console window by right clicking on the page and selecting "Inspect Element", or by hitting F12.
In the console, type...

David's answer provides the meaning of each access modifier. As for when to use each, I'd suggest making public all classes and the methods of each class that are meant for external use (its API), and everything else private.
Over time you'll develop a sense for when to make some classes package-private and when to declare certain methods protected for use in subclasses.
Python, like most modern programming languages, does not support "goto". Instead, you must use control functions. There are essentially two ways to do this.
1. Loops
An example of how you could do exactly what your SmallBasic example does is as follows:
while True :
print "Poo"
It's that simple.
2. Recursion
def the_func() :
print "Poo"
the_func()
the_func()
Note on Recursion: Only do this if you have a specific number of times you want to go back to the beginning (in which case add a case when the recursion should stop). It is a bad idea to do an infinite recursion like I define above, because you will eventually run out of memory!
#Alan's Toolkit for conversions
invalid_input = True
def start() :
print ("Welcome to the converter toolkit made by Alan.")
op = input ("Please input what operation you wish to perform. 1 for Fahrenheit to Celsius, 2 for meters to centimetres and 3 for megabytes to gigabytes")
if op == "1":
#stuff
invalid_input = False # Set to False because input was valid
elif op == "2":
#stuff
invalid_input = False # Set to False because input was valid
elif op == "3": # you still have this as "if"; I would recommend keeping it as elif
#stuff
invalid_input = False # Set to False because input was valid
else:
print ("Sorry, that was an invalid command!")
while invalid_input : # this will loop until invalid_input is set to be True

the key point is finding the right path where your grunt was installed.
I installed grunt through npm, but my grunt path was /Users/${whoyouare}/.npm-global/lib/node_modules/grunt/bin/grunt
. So after I added /Users/${whoyouare}/.npm-global/lib/node_modules/grunt/bin
to ~/.bash_profile
,and source ~/.bash_profile
, It worked.
So the steps are as followings:
1. find the path where your grunt was installed(when you installed grunt, it told you. if you don't remember, you can install it one more time)
2. vi ~/.bash_profile
3. export PATH=$PATH:/your/path/where/grunt/was/installed
4. source ~/.bash_profile
You can refer http://www.hongkiat.com/blog/grunt-command-not-found/
Using $emit and $broadcast, (as mentioned by walv in the comments above)
To fire an event upwards (from child to parent)
$scope.$emit('myTestEvent', 'Data to send');
To fire an event downwards (from parent to child)
$scope.$broadcast('myTestEvent', {
someProp: 'Sending you some data'
});
and finally to listen
$scope.$on('myTestEvent', function (event, data) {
console.log(data);
});

Enjoy :)
If this error occurs when you want to use a classvariable in a new form, you should put the class definition in the
Formname.Designer.cs
instead of the Formname.cs file.
Using Collections#addAll()
String[] words = {"ace","boom","crew","dog","eon"};
List<String> arrayList = new ArrayList<>();
Collections.addAll(arrayList, words);
If the string you need to append is SVG and you add the proper namespace, you can parse the string as XML and append to the parent.
var xml = jQuery.parseXML('<circle xmlns="http://www.w3.org/2000/svg" cx="100" cy="50" r="40" stroke="black" stroke-width="2" fill="red"/>');
$("svg").append(xml.documentElement))
Create a concrete class that inherits the abstract class and then test the functions the concrete class inherits from the abstract class.
In Apache 2.4, there's a new stock module called mod_ratelimit. For emulating modem speeds, you can use mod_dialup. Though I don't see why you just couldn't use mod_ratelimit for everything.
For my answer, it is worth remembering that the TPL (Task-Parallel-Library), Task
class and TaskStatus
enumeration were introduced prior to the async-await keywords and the async-await keywords were not the original motivation of the TPL.
In the context of methods marked as async
, the resulting Task
is not a Task
representing the execution of the method, but a Task
for the continuation of the method.
This is only able to make use of a few possible states:
I understand that Running
could appear to have been a better default than WaitingForActivation
, however this could be misleading, as the majority of the time, an async method being executed is not actually running (i.e. it may be await
-ing something else). The other option may have been to add a new value to TaskStatus
, however this could have been a breaking change for existing applications and libraries.
All of this is very different to when making use of Task.Run
which is a part of the original TPL, this is able to make use of all the possible values of the TaskStatus
enumeration.
If you wish to keep track of the status of an async method, take a look at the IProgress(T)
interface, this will allow you to report the ongoing progress. This blog post, Async in 4.5: Enabling Progress and Cancellation in Async APIs will provide further information on the use of the IProgress(T)
interface.
Not exactly answering your question, but I came across your question, while looking for an answer to an issue that I had. Maybe it will help somebody else.
My issue was that cookies were set in server response, but were not saved by the browser.
The server response came back with cookies set:
Set-Cookie:my_cookie=HelloWorld; Path=/; Expires=Wed, 15 Mar 2017 15:59:59 GMT
This is how I solved it.
I used fetch
in the client-side code. If you do not specify credentials: 'include'
in the fetch
options, cookies are neither sent to server nor saved by the browser, even though the server response sets cookies.
Example:
var headers = new Headers();
headers.append('Content-Type', 'application/json');
headers.append('Accept', 'application/json');
return fetch('/your/server_endpoint', {
method: 'POST',
mode: 'same-origin',
redirect: 'follow',
credentials: 'include', // Don't forget to specify this if you need cookies
headers: headers,
body: JSON.stringify({
first_name: 'John',
last_name: 'Doe'
})
})
I hope this helps somebody.
As I outline in this other answer here on StackOverflow, you can do this by timing the download of files of various sizes (start small, ramp up if the connection seems to allow it), ensuring through cache headers and such that the file is really being read from the remote server and not being retrieved from cache. This doesn't necessarily require that you have a server of your own (the files could be coming from S3 or similar), but you will need somewhere to get the files from in order to test connection speed.
That said, point-in-time bandwidth tests are notoriously unreliable, being as they are impacted by other items being downloaded in other windows, the speed of your server, links en route, etc., etc. But you can get a rough idea using this sort of technique.
Simplest way to remove padding and margin is with simple css.
<div class="header" style="margin:0px;padding:0px;">
.....
.....
.....
</div>
Maybe I'm a straight thinker but I'm a bit puzzled, don't you know the column number of your table?
By the way IE6 doesn't honor the colspan="0", with or without a colgroup defined. I tried also to use thead and th to generate the groups of columns but the browser doesn't recognlise the form colspan="0".
I've tried with Firefox 3.0 on windows and linux and it works only with a strict doctype.
You can check a test on several bowser at
http://browsershots.org/http://hsivonen.iki.fi/test/wa10/tables/colspan-0.html
I found the test page here http://hsivonen.iki.fi/test/wa10/tables/colspan-0.html
Edit: Please copy and paste the link, the formatting won't accept the double protocol parts in the link (or I am not so smart to correctly format it).
You can use as the following code;
cd /my_folder && \
rm *.jar && \
svn co path to repo && \
mvn compile package install
It works...
You need to do something like this:
// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");
// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");
// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
// grab the "id" attribute
XmlAttribute idAttribute = aNode.Attributes["id"];
// check if that attribute even exists...
if (idAttribute != null)
{
// if yes - read its current value
string currentValue = idAttribute.Value;
// here, you can now decide what to do - for demo purposes,
// I just set the ID value to a fixed value if it was empty before
if (string.IsNullOrEmpty(currentValue))
{
idAttribute.Value = "515";
}
}
}
// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");
The following adds one line after SearchPattern
.
sed -i '/SearchPattern/aNew Text' SomeFile.txt
It inserts New Text
one line below each line that contains SearchPattern
.
To add two lines, you can use a \
and enter a newline while typing New Text
.
POSIX sed requires a \
and a newline after the a
sed function. [1]
Specifying the text to append without the newline is a GNU sed extension (as documented in the sed
info page), so its usage is not as portable.

While I agree it's not good style to catch a raw Exception, there are ways of handling exceptions which provide for superior logging, and the ability to handle the unexpected. Since you are in an exceptional state, you are probably more interested in getting good information than in response time, so instanceof performance shouldn't be a big hit.
try{
// IO code
} catch (Exception e){
if(e instanceof IOException){
// handle this exception type
} else if (e instanceof AnotherExceptionType){
//handle this one
} else {
// We didn't expect this one. What could it be? Let's log it, and let it bubble up the hierarchy.
throw e;
}
}
However, this doesn't take into consideration the fact that IO can also throw Errors. Errors are not Exceptions. Errors are a under a different inheritance hierarchy than Exceptions, though both share the base class Throwable. Since IO can throw Errors, you may want to go so far as to catch Throwable
try{
// IO code
} catch (Throwable t){
if(t instanceof Exception){
if(t instanceof IOException){
// handle this exception type
} else if (t instanceof AnotherExceptionType){
//handle this one
} else {
// We didn't expect this Exception. What could it be? Let's log it, and let it bubble up the hierarchy.
}
} else if (t instanceof Error){
if(t instanceof IOError){
// handle this Error
} else if (t instanceof AnotherError){
//handle different Error
} else {
// We didn't expect this Error. What could it be? Let's log it, and let it bubble up the hierarchy.
}
} else {
// This should never be reached, unless you have subclassed Throwable for your own purposes.
throw t;
}
}
Windows Users Only
This is a bit late but just figured that some answers are to go to the bios settings but for me, I was able to resolve this by just disabling the hyper-v feature. We do this by following these steps:
My Problem:
My solution (uses the Windows function _wcstod_l):
// string to convert. Note: decimal seperator is ',' here
std::wstring str = L"1,101";
// Use this for error detection
wchar_t* stopString;
// Create a locale for "C". Thus a '.' is expected as decimal separator
double dbl = _wcstod_l(str.c_str(), &stopString, _create_locale(LC_ALL, "C"));
if (wcslen(stopString) != 0)
{
// ... error handling ... we'll run into this because of the separator
}
HTH ... took me pretty long to get to this solution. And I still have the feeling that I don't know enough about string localization and stuff...
Use:
string str = "Hello";
char[] characters = str.ToCharArray();
If you have a single character string, You can also try
string str = "A";
char character = char.Parse(str);
//OR
string str = "A";
char character = str.ToCharArray()[0];
wp_register_script('custom-js',WP_PLUGIN_URL.'/PLUGIN_NAME/js/custom.js',array(),NULL,true);
wp_enqueue_script('custom-js');
$wnm_custom = array( 'template_url' => get_bloginfo('template_url') );
wp_localize_script( 'custom-js', 'wnm_custom', $wnm_custom );
and in custom.js
alert(wnm_custom.template_url);
After trying all the above and using the answer from @Aaron Hall, I was getting memory errors for a ~90 Mb file on a computer running Window 10, 8 Gb RAM and Python 3.5 32-bit. I was recommended by a colleague to use numpy
instead and it works wonders.
By far, the fastest to read an entire binary file (that I have tested) is:
import numpy as np
file = "binary_file.bin"
data = np.fromfile(file, 'u1')
Multitudes faster than any other methods so far. Hope it helps someone!
I found a way to do it without replacing the slashes
select CONVERT(VARCHAR(10), GETDATE(), 112)
This would return: "YYYYMMDD"
Depends on what you have. If your svg icon is just a path, then it's easy enough to add that glyph by just copying the 'd' attribute to a new <glyph> element. However, the path needs to be scaled to the font's coordinate system (the EM-square, which typically is [0,0,2048,2048] - the standard for Truetype fonts) and aligned with the baseline you want.
Not all browsers support svg fonts however, so you're going to have to convert it to other formats too if you want it to work everywhere.
Fontforge can import svg files (select a glyph slot, File > Import and then select your svg image), and you can then convert to all the relevant font formats (svg, truetype, woff etc).

As chmullig wrote, use Jenkins. Some additional points:
In fact, arguably it was Oracle who did the forking! And technically, too, that's kinda what happened.
It's interesting to see what comes out of "Hudson" though. While the "Winston summarizes the state and rosy future of the Hudson project" stuff they posted on the (new) Hudson website originally seemed like odd humour to me, perhaps this was a purposeful takeover, and the Sonatype guys actually have some big ideas up their sleeve. This analysis, suggesting a deliberate strategy by Oracle/Sonatype to oust Kohsuke and crew to create a more "enterprisy" Hudson is a very interesting read!
In any case, this brief comparison a fortnight after the split—while not exactly scientific—shows Jenkins to be by far more active of the two projects.
...and a little background info:
The creator of Hudson, Kohsuke Kawaguchi, started the project on his free time, even if he was working for Sun Microsystems and later paid by them to develop it further. As @erickson noted at another SO question,
[Hudson/Jenkins] is the product of a single genius intellect—Kohsuke Kawaguchi. Because of that, it's consistent, coherent, and rock solid.
After the acquisition by Oracle, Kohsuke didn't hang around for long (due to lack of monitors...? ;-]), and went to work for CloudBees. What started in late 2010 as conflict over tools between the dev community and Oracle and ended in the rename/fork/split is well documented in the links chmullig provided. To me, that whole conundrum speaks, perhaps more than anything else, to Oracle's utter inability or unwillingness to sponsor an open-source project in a way that keeps all parties (Oracle, developers, users) happy. It's not in their DNA or something, as we've seen in other cases too.
Given all of the above, I would personally follow Kohsuke and other core developers in this matter, and go with Jenkins.
You did two mistakes . I think you misplace FROM and WHERE keywords.
SELECT DISTINCT Description, Date as treatmentDate
FROM doothey.Patient P, doothey.Account A, doothey.AccountLine AL, doothey.Item.I --Here you use "." operator to "I" alias
WHERE -- WHERE should be located here.
P.PatientID = A.PatientID
AND A.AccountNo = AL.AccountNo
AND AL.ItemNo = I.ItemNo
AND (p.FamilyName = 'Stange' AND p.GivenName = 'Jessie');
I made my own way based on Caitlin Morris's answer for fetching all folowers and followings on Instagram. Just copy this code, paste in browser console and wait for a few seconds.
You need to use browser console from instagram.com tab to make it works.

You won't be able to make an ajax call to http://www.ecb.europa.eu/stats/eurofxref/eurofxref-daily.xml
from a file deployed at http://run.jsbin.com
due to the same-origin policy.
As the source (aka origin) page and the target URL are at different domains (run.jsbin.com
and www.ecb.europa.eu
), your code is actually attempting to make a Cross-domain (CORS) request, not an ordinary GET
.
In a few words, the same-origin policy says that browsers should only allow ajax calls to services at the same domain of the HTML page.
A page at http://www.example.com/myPage.html
can only directly request services that are at http://www.example.com
, like http://www.example.com/api/myService
. If the service is hosted at another domain (say http://www.ok.com/api/myService
), the browser won't make the call directly (as you'd expect). Instead, it will try to make a CORS request.
To put it shortly, to perform a (CORS) request* across different domains, your browser:
Origin
header in the original request (with the page's domain as value) and perform it as usual; and thenAccess-Control-Allow-Origin
is one of them) allowing the CORS request, the browse will complete the call (almost** exactly the way it would if the HTML page was at the same domain).
* The above depicts the steps in a simple request, such as a regular GET
with no fancy headers. If the request is not simple (like a POST
with application/json
as content type), the browser will hold it a moment, and, before fulfilling it, will first send an OPTIONS
request to the target URL. Like above, it only will continue if the response to this OPTIONS
request contains the CORS headers. This OPTIONS
call is known as preflight request.
** I'm saying almost because there are other differences between regular calls and CORS calls. An important one is that some headers, even if present in the response, will not be picked up by the browser if they aren't included in the Access-Control-Expose-Headers
header.
Was it just a typo? Sometimes the JavaScript code has just a typo in the target domain. Have you checked? If the page is at www.example.com
it will only make regular calls to www.example.com
! Other URLs, such as api.example.com
or even example.com
or www.example.com:8080
are considered different domains by the browser! Yes, if the port is different, then it is a different domain!
Add the headers. The simplest way to enable CORS is by adding the necessary headers (as Access-Control-Allow-Origin
) to the server's responses. (Each server/language has a way to do that - check some solutions here.)
Last resort: If you don't have server-side access to the service, you can also mirror it (through tools such as reverse proxies), and include all the necessary headers there.
Calling a JavaScript function from code behind
Step 1 Add your Javascript code
<script type="text/javascript" language="javascript">
function Func() {
alert("hello!")
}
</script>
Step 2 Add 1 Script Manager in your webForm and Add 1 button too
Step 3 Add this code in your button click event
ScriptManager.RegisterStartupScript(this.Page, Page.GetType(), "text", "Func()", true);
If you need refresh, this is another posibility:
setTimeout(function () {
$("#jsSegurosProductos").jsGrid("refresh");
}, 1000);
Below is the pseudo-code for using sub-query using Criteria API.
CriteriaBuilder criteriaBuilder = entityManager.getCriteriaBuilder();
CriteriaQuery<Object> criteriaQuery = criteriaBuilder.createQuery();
Root<EMPLOYEE> from = criteriaQuery.from(EMPLOYEE.class);
Path<Object> path = from.get("compare_field"); // field to map with sub-query
from.fetch("name");
from.fetch("id");
CriteriaQuery<Object> select = criteriaQuery.select(from);
Subquery<PROJECT> subquery = criteriaQuery.subquery(PROJECT.class);
Root fromProject = subquery.from(PROJECT.class);
subquery.select(fromProject.get("requiredColumnName")); // field to map with main-query
subquery.where(criteriaBuilder.and(criteriaBuilder.equal("name",name_value),criteriaBuilder.equal("id",id_value)));
select.where(criteriaBuilder.in(path).value(subquery));
TypedQuery<Object> typedQuery = entityManager.createQuery(select);
List<Object> resultList = typedQuery.getResultList();
Also it definitely needs some modification as I have tried to map it according to your query. Here is a link http://www.ibm.com/developerworks/java/library/j-typesafejpa/ which explains concept nicely.
Use:
pandas.set_option('display.max_columns', 7)
This will force Pandas to display the 7 columns you have. Or more generally:
pandas.set_option('display.max_columns', None)
which will force it to display any number of columns.
Explanation: the default for max_columns
is 0
, which tells Pandas to display the table only if all the columns can be squeezed into the width of your console.
Alternatively, you can change the console width (in chars) from the default of 80 using e.g:
pandas.set_option('display.width', 200)
\d
means a digit in most languages. You can also use [0-9]
in all languages. For the "period or comma" use [\.,]
. Depending on your language you may need more backslashes based on how you quote the expression. Ultimately, the regular expression engine needs to see a single backslash.
*
means "zero-or-more", so \d*
and [0-9]*
mean "zero or more numbers". ?
means "zero-or-one". Neither of those qualifiers means exactly one. Most languages also let you use {m,n}
to mean "between m and n" (ie: {1,2} means "between 1 and 2")
Since the dot or comma and additional numbers are optional, you can put them in a group and use the ?
quantifier to mean "zero-or-one" of that group.
Putting that all together you can use:
\d{1,2}([\.,][\d{1,2}])?
Meaning, one or two digits \d{1,2}
, followed by zero-or-one of a group (...)?
consisting of a dot or comma followed by one or two digits [\.,]\d{1,2}
I just bumped into the same problem and I used the following solution (all from Package Manager Console)
PM> Enable-Migrations -MigrationsDirectory "Migrations\ContextA" -ContextTypeName MyProject.Models.ContextA
PM> Enable-Migrations -MigrationsDirectory "Migrations\ContextB" -ContextTypeName MyProject.Models.ContextB
This will create 2 separate folders in the Migrations folder. Each will contain the generated Configuration.cs
file. Unfortunately you still have to rename those Configuration.cs
files otherwise there will be complaints about having two of them. I renamed my files to ConfigA.cs
and ConfigB.cs
EDIT: (courtesy Kevin McPheat) Remember when renaming the Configuration.cs files, also rename the class names and constructors /EDIT
With this structure you can simply do
PM> Add-Migration -ConfigurationTypeName ConfigA
PM> Add-Migration -ConfigurationTypeName ConfigB
Which will create the code files for the migration inside the folder next to the config files (this is nice to keep those files together)
PM> Update-Database -ConfigurationTypeName ConfigA
PM> Update-Database -ConfigurationTypeName ConfigB
And last but not least those two commands will apply the correct migrations to their corrseponding databases.
EDIT 08 Feb, 2016: I have done a little testing with EF7 version 7.0.0-rc1-16348
I could not get the -o|--outputDir option to work. It kept on giving Microsoft.Dnx.Runtime.Common.Commandline.CommandParsingException: Unrecognized command or argument
However it looks like the first time an migration is added it is added into the Migrations folder, and a subsequent migration for another context is automatically put into a subdolder of migrations.
The original names ContextA
seems to violate some naming conventions so I now use ContextAContext
and ContextBContext
. Using these names you could use the following commands:
(note that my dnx still works from the package manager console and I do not like to open a separate CMD window to do migrations)
PM> dnx ef migrations add Initial -c "ContextAContext"
PM> dnx ef migrations add Initial -c "ContextBContext"
This will create a model snapshot and a initial migration in the Migrations
folder for ContextAContext
. It will create a folder named ContextB
containing these files for ContextBContext
I manually added a ContextA
folder and moved the migration files from ContextAContext
into that folder. Then I renamed the namespace inside those files (snapshot file, initial migration and note that there is a third file under the initial migration file ... designer.cs). I had to add .ContextA
to the namespace, and from there the framework handles it automatically again.
Using the following commands would create a new migration for each context
PM> dnx ef migrations add Update1 -c "ContextAContext"
PM> dnx ef migrations add Update1 -c "ContextBContext"
and the generated files are put in the correct folders.

As the name suggests ClassNotFoundException
in Java is a subclass of java.lang.Exception
and Comes when Java Virtual Machine tries to load a particular class and doesn't found the requested class in classpath.
Another important point about this Exception is that, It is a checked Exception and you need to provide explicitly Exception handling while using methods which can possibly throw ClassNotFoundException
in java either by using try-catch block or by using throws clause.
public class ClassNotFoundException
extends ReflectiveOperationException
Thrown when an application tries to load in a class through its string name using:
but no definition for the class with the specified name could be found.
You can use a $where. Just be aware it will be fairly slow (has to execute Javascript code on every record) so combine with indexed queries if you can.
db.T.find( { $where: function() { return this.Grade1 > this.Grade2 } } );
or more compact:
db.T.find( { $where : "this.Grade1 > this.Grade2" } );
you can use $expr
as described in recent answer
As you are asking for a word and not for a string, I would like to present a solution which is not sensitive to prefixes / suffixes and ignores case:
#!/usr/bin/env python
import re
def is_word_in_text(word, text):
"""
Check if a word is in a text.
Parameters
----------
word : str
text : str
Returns
-------
bool : True if word is in text, otherwise False.
Examples
--------
>>> is_word_in_text("Python", "python is awesome.")
True
>>> is_word_in_text("Python", "camelCase is pythonic.")
False
>>> is_word_in_text("Python", "At the end is Python")
True
"""
pattern = r'(^|[^\w]){}([^\w]|$)'.format(word)
pattern = re.compile(pattern, re.IGNORECASE)
matches = re.search(pattern, text)
return bool(matches)
if __name__ == '__main__':
import doctest
doctest.testmod()
If your words might contain regex special chars (such as +
), then you need re.escape(word)
I think a correct approach would be by means of Regex:
String fileContent = <text from file>;
String[] words = Pattern.compile("\\s+").split(fileContent);
System.out.println("File has " + words.length + " words");
Hope it helps. The "\s+" meaning is in Pattern javadoc
Extension of the above-mentioned answer. I wrote a UNIX command so I can easily do it in my workflow.
Copy Google Drive Image URL
https://drive.google.com/file/d/XXXX/view?usp=sharing
Command:
echo https://drive.google.com/uc\?export\=view\&id\=`echo $(pbpaste) | cut -d '/' -f 6`
Output:
https://drive.google.com/uc?export=view&id=XXXX
P.S. If you copy the command from here. Make sure to copy the Google Drive image URL again. :P
No need to change anything in the Step 2 command as it takes from Clipboard. Make sure it is copied in right format E.g.

Try this Javascript (jquery) code. Its an ajax request to an external URL. Use the callback function to fire any code:
<script type="text/javascript">
$(function() {
$('form').submit(function(){
$.post('http://example.com/upload', function() {
window.location = 'http://google.com';
});
return false;
});
});
</script>
please test below solution:
first open command prompt cmd ==> window+r
and go to the location where laravel installed.
try composer require laravel/laravel
Here is the solution I found: On the project tree "app", right click mouse button to get the context menu. Select "open module setting", on the tree "app" - "properties" tab, select the existing "build tools version" you have. The gradle will start to build.
The posted answers are very good when working with data.frame
s. However, these tasks can be pretty inefficient from a memory perspective. With large data, removing a column can take an unusually long amount of time and/or fail due to out of memory
errors. Package data.table
helps address this problem with the :=
operator:
library(data.table)
> dt <- data.table(a = 1, b = 1, c = 1)
> dt[,a:=NULL]
b c
[1,] 1 1
I should put together a bigger example to show the differences. I'll update this answer at some point with that.

Create a model which contains your list and other things you need for the view.
For example:
public class MyModel
{
public List<string> _MyList { get; set; }
}
From the action method put your desired list to the Model, _MyList
property, like:
public ActionResult ArticleList(MyModel model)
{
model._MyList = new List<string>{"item1","item2","item3"};
return PartialView(@"~/Views/Home/MyView.cshtml", model);
}
In your view access the model as follows
@model MyModel
foreach (var item in Model)
{
<div>@item</div>
}
I think it will help for start.
If you are not using "-XX:HeapDumpPath" option then in case of JBoss EAP/As by default the heap dump file will be generated in "JBOSS_HOME/bin" directory.
https://gist.github.com/danomanion/6175687 proposes an elegant solution, using a custom bullet in place of a background image:
a.logo {
display: list-item;
list-style-image: url("../images/desired-background.png");
list-style-position: inside;
}
By including this within a
@media print {
}
block, I'm able to replace a white-on-transparent logo on the screen, rendered as a background-image, with a black-on-transparent logo for print.
You should put your model class before create_all()
call, like this:
from flask import Flask
from flask_sqlalchemy import SQLAlchemy
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql+psycopg2://login:pass@localhost/flask_app'
db = SQLAlchemy(app)
class User(db.Model):
id = db.Column(db.Integer, primary_key=True)
username = db.Column(db.String(80), unique=True)
email = db.Column(db.String(120), unique=True)
def __init__(self, username, email):
self.username = username
self.email = email
def __repr__(self):
return '<User %r>' % self.username
db.create_all()
db.session.commit()
admin = User('admin', '[email protected]')
guest = User('guest', '[email protected]')
db.session.add(admin)
db.session.add(guest)
db.session.commit()
users = User.query.all()
print users
If your models are declared in a separate module, import them before calling create_all()
.
Say, the User
model is in a file called models.py
,
from flask import Flask
from flask_sqlalchemy import SQLAlchemy
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'postgresql+psycopg2://login:pass@localhost/flask_app'
db = SQLAlchemy(app)
# See important note below
from models import User
db.create_all()
db.session.commit()
admin = User('admin', '[email protected]')
guest = User('guest', '[email protected]')
db.session.add(admin)
db.session.add(guest)
db.session.commit()
users = User.query.all()
print users
Important note: It is important that you import your models after initializing the db
object since, in your models.py
_you also need to import the db
object from this module.
According to documentation: to verify host or peer certificate you need to specify alternate certificates with the CURLOPT_CAINFO
option or a certificate directory can be specified with the CURLOPT_CAPATH
option.
Also look at CURLOPT_SSL_VERIFYHOST:
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
A too late answer :)
If you apply float to tr
elements, you can space between two rows with margin
attribute.
table tr{
float: left
width: 100%;
}
tr.classname {
margin-bottom:5px;
}
From backdrop-filter
...apply graphical effects such as blurring or color shifting to the area behind an element. Because it applies to everything behind the element, to see the effect you must make the element or its background at least partially transparent.
If you're creating redirections, test with curl to avoid browser caching issues. Use -I to fetch http headers only. Use -L to follow all redirections.
If you are using LINUX, you can use pyALSAAUDIO. For windows, we have PyAudio and there is also a library called SoundAnalyse.
I found an example for Linux here:
#!/usr/bin/python
## This is an example of a simple sound capture script.
##
## The script opens an ALSA pcm for sound capture. Set
## various attributes of the capture, and reads in a loop,
## Then prints the volume.
##
## To test it out, run it and shout at your microphone:
import alsaaudio, time, audioop
# Open the device in nonblocking capture mode. The last argument could
# just as well have been zero for blocking mode. Then we could have
# left out the sleep call in the bottom of the loop
inp = alsaaudio.PCM(alsaaudio.PCM_CAPTURE,alsaaudio.PCM_NONBLOCK)
# Set attributes: Mono, 8000 Hz, 16 bit little endian samples
inp.setchannels(1)
inp.setrate(8000)
inp.setformat(alsaaudio.PCM_FORMAT_S16_LE)
# The period size controls the internal number of frames per period.
# The significance of this parameter is documented in the ALSA api.
# For our purposes, it is suficcient to know that reads from the device
# will return this many frames. Each frame being 2 bytes long.
# This means that the reads below will return either 320 bytes of data
# or 0 bytes of data. The latter is possible because we are in nonblocking
# mode.
inp.setperiodsize(160)
while True:
# Read data from device
l,data = inp.read()
if l:
# Return the maximum of the absolute value of all samples in a fragment.
print audioop.max(data, 2)
time.sleep(.001)
A possible refinement to Thomas's excellent answer is to have Linux and possibly OSX also try to open ports and return only those which could be opened. This is because Linux, at least, lists a boatload of ports as files in /dev/ which aren't connected to anything. If you're running in a terminal, /dev/tty is the terminal in which you're working and opening and closing it can goof up your command line, so the glob is designed to not do that. Code:
# ... Windows code unchanged ...
elif sys.platform.startswith ('linux'):
temp_list = glob.glob ('/dev/tty[A-Za-z]*')
result = []
for a_port in temp_list:
try:
s = serial.Serial(a_port)
s.close()
result.append(a_port)
except serial.SerialException:
pass
return result
This modification to Thomas's code has been tested on Ubuntu 14.04 only.
I was facing the same issue in eclipse so I am telling you the same step that I did you just need to go eclipse installed folder where you will find the file named eclipse.ini in my case the location was
C:\Users\comp\eclipse\jee-2018-12\eclipse
you can find your location.
in that location, open eclipse.ini in text mode and there you will find some below text
-Xms256m
-Xmx1024m
change it to
-Xms512m -Xmx1024m
I hope that will help you 100% as checked in my System ;-)
This function gets the series names, puts them into an array, sorts the array and based on that defines the plotting order which will give the desired output.

You don't say what platform you're targeting. Referring to tables as files, though, leads me to believe that you're NOT running DB2 on Linux, UNIX or Windows (LUW).
However, if you are on DB2 LUW, see the MERGE statement:
For your example statement, this would be written as:
merge into file1 a
using (select anotherfield, something from file2) b
on substr(a.firstfield,10,20) = substr(b.anotherfield,1,10)
when matched and a.firstfield like 'BLAH%'
then update set a.firstfield = 'BIT OF TEXT' || b.something;
Please note: For DB2, the third argument of the SUBSTR function is the number of bytes to return, not the ending position. Therefore, SUBSTR(a.firstfield,10,20) returns CHAR(20). However, SUBSTR(b.anotherfield,1,10) returns CHAR(10). I'm not sure if this was done on purpose, but it may affect your comparison.
The following is what i just used in my project .And hope it can help you

$replace = array('“', '’', '…', '—', '–', '‘', 'é', '', '•', '˜', '”');
$content = str_replace($find, $replace, $content);
Its the method i use and help alot. Thanks!

When getting/setting checkbox state, one may encounter these phenomenons:
.trigger("click");
Does check an unchecked checkbox, but do not add the checked attribute. If you use triggers, do not try to get the state with "checked" attribute.
.attr("checked", "");
Does not uncheck the checkbox...
If you have a single play that you want to loop over the items, define that list in group_vars/all or somewhere else that makes sense:
all_items:
- first
- second
- third
- fourth
Then your task can look like this:
- name: List items or default list
debug:
var: item
with_items: "{{ varlist | default(all_items) }}"
Pass in varlist as a JSON array:
ansible-playbook <playbook_name> --extra-vars='{"varlist": [first,third]}'
Prior to that, you might also want a task that checks that each item in varlist is also in all_items:
- name: Ensure passed variables are in all_items
fail:
msg: "{{ item }} not in all_items list"
when: item not in all_items
with_items: "{{ varlist | default(all_items) }}"
Okay, as all posts say, if you want to make it search engine-friendly then bots can scrape for sure.
But you can still do a few things, and it may be affective for 60-70 % scraping bots.
Make a checker script like below.
If a particular IP address is visiting very fast then after a few visits (5-10) put its IP address + browser information in a file or database.
(This would be a background process and running all time or scheduled after a few minutes.) Make one another script that will keep on checking those suspicious IP addresses.
Case 1. If the user Agent is of a known search engine like Google, Bing, Yahoo (you can find more information on user agents by googling it). Then you must see http://www.iplists.com/. This list and try to match patterns. And if it seems like a faked user-agent then ask to fill in a CAPTCHA on the next visit. (You need to research a bit more on bots IP addresses. I know this is achievable and also try whois of the IP address. It can be helpful.)
Case 2. No user agent of a search bot: Simply ask to fill in a CAPTCHA on the next visit.
I've solved that problem.
Since readonly="readonly"
tag is not working (I've tried different browsers), you have to use disabled="disabled"
instead. But your checkbox's value will not post then...
Here is my solution:
To get "readonly" look and POST checkbox's value in the same time, just add a hidden "input" with the same name and value as your checkbox. You have to keep it next to your checkbox or between the same <form></form>
tags:
<input type="checkbox" checked="checked" disabled="disabled" name="Tests" value="4">SOME TEXT</input>
<input type="hidden" id="Tests" name="Tests" value="4" />
Also, just to let ya'll know readonly="readonly", readonly="true", readonly="",
or just READONLY
will NOT solve this! I've spent few hours to figure it out!
This reference is also NOT relevant (may be not yet, or not anymore, I have no idea): http://www.w3schools.com/tags/att_input_readonly.asp

Use the fromkeys
function to initialize a dictionary with any default value. In your case, you will initialize with None
since you don't have a default value in mind.
empty_dict = dict.fromkeys(['apple','ball'])
this will initialize empty_dict
as:
empty_dict = {'apple': None, 'ball': None}
As an alternative, if you wanted to initialize the dictionary with some default value other than None
, you can do:
default_value = 'xyz'
nonempty_dict = dict.fromkeys(['apple','ball'],default_value)
class PriorityQueue<T>
{

public PriorityQueue(IComparer<T> comparer) : this(16, comparer) { }

this.heap = new T[capacity];
}
public void push(T v)
{
if (Count >= heap.Length) Array.Resize(ref heap, Count * 2);
heap[Count] = v;
SiftUp(Count++);
}
public T pop()
{
var v = top();
heap[0] = heap[--Count];
if (Count > 0) SiftDown(0);
return v;
}
public T top()
{
if (Count > 0) return heap[0];
throw new InvalidOperationException("??????");
}
void SiftUp(int n)
{
var v = heap[n];
for (var n2 = n / 2; n > 0 && comparer.Compare(v, heap[n2]) > 0; n = n2, n2 /= 2) heap[n] = heap[n2];
heap[n] = v;
}
void SiftDown(int n)
{
var v = heap[n];
for (var n2 = n * 2; n2 < Count; n = n2, n2 *= 2)
{
if (n2 + 1 < Count && comparer.Compare(heap[n2 + 1], heap[n2]) > 0) n2++;
if (comparer.Compare(v, heap[n2]) >= 0) break;
heap[n] = heap[n2];
}
heap[n] = v;

paste(sdata, collapse = '')
Here is a non-regex heap allocation friendly fast solution which was what I was looking for.
Unsafe edition.
public static unsafe void ToAlphaNumeric(ref string input)
{
fixed (char* p = input)
{
int offset = 0;
for (int i = 0; i < input.Length; i++)
{
if (char.IsLetterOrDigit(p[i]))
{
p[offset] = input[i];
offset++;
}
}
((int*)p)[-1] = offset; // Changes the length of the string
p[offset] = '\0';
}
}
And for those who don't want to use unsafe or don't trust the string length hack.
public static string ToAlphaNumeric(string input)
{
int j = 0;
char[] newCharArr = new char[input.Length];
for (int i = 0; i < input.Length; i++)
{
if (char.IsLetterOrDigit(input[i]))
{
newCharArr[j] = input[i];
j++;
}
}
Array.Resize(ref newCharArr, j);
return new string(newCharArr);
}
The only reason that I know of why a formula wouldn't be available to summarize on is if it didn't reference any database fields or whose value wasn't dynamic throughout sections of the report. For example, if you have a formula that returns a constant it won't be available. Or if it only references a field that is set throughout the report and returns a value based on that field, like "if {parameter}=1 then 1" would not be available either.
In general, the formula's value should not be static through the sections of the report you're summarizing over (Though the way Crystal determines this is beyond me and this doesn't seem to be a hard and fast rule)
EDIT: One other reason why a formula wouldn't be available is if you're already using a summary function in that formula. Only one level of summaries at a time!
<?php
$con=mysqli_connect("localhost","my_user","my_password","my_db");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql="SELECT Lastname,Age FROM Persons ORDER BY Lastname";
if ($result=mysqli_query($con,$sql))
{
// Return the number of rows in result set
$rowcount=mysqli_num_rows($result);
echo "number of rows: ",$rowcount;
// Free result set
mysqli_free_result($result);
}
mysqli_close($con);
?>
it is best way (I think) to get the number of special row in mysql with php.
It's almost always advisable to not use scriptlets in your JSP. They're considered bad form. Instead, try using JSTL (JSP Standard Tag Library) combined with EL (Expression Language) to run the conditional logic you're trying to do. As an added benefit, JSTL also includes other important features like looping.
Instead of:
<%String user=request.getParameter("user"); %>
<%if(user == null || user.length() == 0){
out.print("I see! You don't have a name.. well.. Hello no name");
}
else {%>
<%@ include file="response.jsp" %>
<% } %>
Use:
<c:choose>
<c:when test="${empty user}">
I see! You don't have a name.. well.. Hello no name
</c:when>
<c:otherwise>
<%@ include file="response.jsp" %>
</c:otherwise>
</c:choose>
Also, unless you plan on using response.jsp somewhere else in your code, it might be easier to just include the html in your otherwise statement:
<c:otherwise>
<h1>Hello</h1>
${user}
</c:otherwise>
Also of note. To use the core tag, you must import it as follows:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
You want to make it so the user will receive a message when the user submits a username. The easiest way to do this is to not print a message at all when the "user" param is null
. You can do some validation to give an error message when the user submits null
. This is a more standard approach to your problem. To accomplish this:
In scriptlet:
<% String user = request.getParameter("user");
if( user != null && user.length() > 0 ) {
<%@ include file="response.jsp" %>
}
%>
In jstl:
<c:if test="${not empty user}">
<%@ include file="response.jsp" %>
</c:if>
To pull data for the last 3 days, not the current date :
date(timestamp) >= curdate() - 3
AND date(timestamp) < curdate()
Example:
SELECT *
FROM user_login
WHERE age > 18
AND date(timestamp) >= curdate() - 3
AND date(timestamp) < curdate()
LIMIT 10

I just want to add, in case you need just certain functions imported from your tools.js, then you can use a destructuring assignment which is supported in node.js since version 6.4 - see node.green.
Example: (both files are in the same folder)
tools.js
module.exports = {
sum: function(a,b) {
return a + b;
},
isEven: function(a) {
return a % 2 == 0;
}
};
main.js
const { isEven } = require('./tools.js');
console.log(isEven(10));
output: true
This also avoids that you assign those functions as properties of another object as its the case in the following (common) assignment:
const tools = require('./tools.js');
where you need to call tools.isEven(10)
.
NOTE:
Don't forget to prefix your file name with the correct path - even if both files are in the same folder, you need to prefix with ./
From Node.js docs:
Without a leading '/', './', or '../' to indicate a file, the module must either be a core module or is loaded from a node_modules folder.
Late but as a note: after upgrading Chrome to v/81, all check boxes & radio buttons turned blue. So here is a dead simple solution if you ain't okay with blue but with grayscale;
input[type='checkbox'], input[type='radio'] { filter: grayscale(1) }
See more on MDN:
https://developer.mozilla.org/en-US/docs/Web/CSS/filter
https://developer.mozilla.org/en-US/docs/Web/CSS/filter-function/grayscale
well, thought I should mention a solution I came across through some trying. Discovered whilst fixing a defect of someone comparing dates as strings.
new Date(Date.parse('01-01-1970 01:03:44'))
The checkbox is in a td
, so need to get the parent first:
$("input:checkbox").on("change", function() {
$(this).parent().next().find("label").text("TESTTTT");
});
Alternatively, find a label which has a for
with the same id
(perhaps more performant than reverse traversal) :
$("input:checkbox").on("change", function() {
$("label[for='" + $(this).attr('id') + "']").text("TESTTTT");
});
Or, to be more succinct just this.id
:
$("input:checkbox").on("change", function() {
$("label[for='" + this.id + "']").text("TESTTTT");
});
If the src is https and the certificate has expired -- and even if you've made an exception -- firefox will still display this error message, and you can see the exact reason why if you look at the request under the network tab.
I think that the most elegant way to do it is to implement custom Flash Scope in Spring MVC.
the main idea for the flash scope is to store data from one controller till next redirect in second controller
Please refer to my answer on the custom scope question:
The only thing that is missing in this code is the following xml configuration:
<bean id="flashScopeInterceptor" class="com.vanilla.springMVC.scope.FlashScopeInterceptor" />
<bean id="handlerMapping" class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
<property name="interceptors">
<list><ref bean="flashScopeInterceptor"/></list>
</property>
</bean>
This should work for every default repo:
git pull origin master
If your default branch is different than master
, you will need to specify the branch name:
git pull origin my_default_branch_name
The problem you face is that you try to assign the return of imshow
(which is an matplotlib.image.AxesImage
to an existing axes object.
The correct way of plotting image data to the different axes in axarr
would be
f, axarr = plt.subplots(2,2)
axarr[0,0].imshow(image_datas[0])
axarr[0,1].imshow(image_datas[1])
axarr[1,0].imshow(image_datas[2])
axarr[1,1].imshow(image_datas[3])
The concept is the same for all subplots, and in most cases the axes instance provide the same methods than the pyplot (plt) interface.
E.g. if ax
is one of your subplot axes, for plotting a normal line plot you'd use ax.plot(..)
instead of plt.plot()
. This can actually be found exactly in the source from the page you link to.
You can use CSS to hide the close button instead of JavaScript:
.ui-dialog-titlebar-close{
display: none;
}
If you don't want to affect all the modals, you could use a rule like
.hide-close-btn .ui-dialog-titlebar-close{
display: none;
}
And apply .hide-close-btn
to the top node of the dialog
Here is a solution for the single column search using PATINDEX.
It also displays the StartPosition, InvalidCharacter and ASCII code.
select line,
patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,Line) as [Position],
substring(line,patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,Line),1) as [InvalidCharacter],
ascii(substring(line,patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,Line),1)) as [ASCIICode]
from staging.APARMRE1
where patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,Line) >0
Things get messy quickly if you are talking about checked-in code in an enterprise environment. We've found that the best approach is to have the web.Release.config contain the following:
<system.web>
<compilation xdt:Transform="RemoveAttributes(debug)" />
<authentication>
<forms xdt:Transform="Replace" timeout="20" requireSSL="true" />
</authentication>
</system.web>
That way, developers are not affected (running in Debug), and only servers that get Release builds are requiring cookies to be SSL.
There's an illegal character at index 16. I'd say it doesn't like the space in the path. You can percent encode special characters like spaces. Replace it with a %20 in this case.
The question I linked to above suggests using URLEncoder:
String thePath = "file://E:/Program Files/IBM/SDP/runtimes/base";
thePath = URLEncoder.encode(thePath, "UTF-8");

Let's make it simple as hell. If you want a single number for the number of dimensions like 2, 3, 4, etc.,
then just use tf.rank()
. But, if you want the exact shape of the tensor then use tensor.get_shape()
with tf.Session() as sess:
arr = tf.random_normal(shape=(10, 32, 32, 128))
a = tf.random_gamma(shape=(3, 3, 1), alpha=0.1)
print(sess.run([tf.rank(arr), tf.rank(a)]))
print(arr.get_shape(), ", ", a.get_shape())
# for tf.rank()
[4, 3]
# for tf.get_shape()
Output: (10, 32, 32, 128) , (3, 3, 1)
I just installed Visual Studio Code v1.25.1. on a Windows 7 Professional SP1 machine. I wanted to understand workspaces in detail, so I spent a few hours figuring out how they work in this version of Visual Studio Code. I thought the results of my research might be of interest to the community.
First, workspaces are referred to by Microsoft in the Visual Studio Code documentation as "multi-root workspaces." In plain English that means "a multi-folder (A.K.A "root") work environment." A Visual Studio Code workspace is simply a collection of folders - any collection you desire, in any order you wish. The typical collection of folders constitutes a software development project. However, a folder collection could be used for anything else for which software code is being developed.
The mechanics behind how Visual Studio Code handles workspaces is a bit complicated. I think the quickest way to convey what I learned is by giving you a set of instructions that you can use to see how workspaces work on your computer. I am assuming that you are starting with a fresh install of Visual Studio Code v1.25.1. If you are using a production version of Visual Studio Code I don't recommend that you follow my instructions because you may lose some or all of your existing Visual Studio Code configuration! If you already have a test version of Visual Studio Code v1.25.1 installed, **and you are willing to lose any configuration that already exists, the following must be done to revert your Visual Studio Code to a fresh installation state:
Delete the following folder (if it exists):
C:\Users\%username%\AppData\Roaming\Code\Workspaces (where "%username%" is the name of the currently logged-on user)
You will be adding folders to Visual Studio Code to create a new workspace. If any of the folders you intend to use to create this new workspace have previously been used with Visual Studio Code, please delete the ".vscode" subfolder (if it exists) within each of the folders that will be used to create the new workspace.
Launch Visual Studio Code. If the Welcome page is displayed, close it. Do the same for the Panel (a horizontal pane) if it is displayed. If you received a message that Git isn't installed click "Remind me later." If displayed, also close the "Untitled" code page that was launched as the default code page. If the Explorer pane is not displayed click "View" on the main menu then click "Explorer" to display the Explorer pane. Inside the Explorer pane you should see three (3) View headers - Open Editors, No Folder Opened, and Outline (located at the very bottom of the Explorer pane). Make sure that, at a minimum, the open editors and no folder opened view headers are displayed.
Visual Studio Code displays a button that reads "Open Folder." Click this button and select a folder of your choice. Visual Studio Code will refresh and the name of your selected folder will have replaced the "No Folder Opened" View name. Any folders and files that exist within your selected folder will be displayed beneath the View name.
Now open the Visual Studio Code Preferences Settings file. There are many ways to do this. I'll use the easiest to remember which is menu File → Preferences → Settings. The Settings file is displayed in two columns. The left column is a read-only listing of the default values for every Visual Studio Code feature. The right column is used to list the three (3) types of user settings. At this point in your test only two user settings will be listed - User Settings and Workspace Settings. The User Settings is displayed by default. This displays the contents of your User Settings .json file. To find out where this file is located, simply hover your mouse over the "User Settings" listing that appears under the OPEN EDITORS View in Explorer. This listing in the OPEN EDITORS View is automatically selected when the "User Settings" option in the right column is selected. The path should be:
C:\Users\%username%\AppData\Roaming\Code\User\settings.json
This settings.json file is where the User Settings for Visual Studio Code are stored.
Now click the Workspace Settings option in the right column of the Preferences listing. When you do this, a subfolder named ".vscode" is automatically created in the folder you added to Explore a few steps ago. Look at the listing of your folder in Explorer to confirm that the .vscode subfolder has been added. Inside the new .vscode subfolder is another settings.json file. This file contains the workspace settings for the folder you added to Explorer a few steps ago.
At this point you have a single folder whose User Settings are stored at:
C:\Users\%username%\AppData\Roaming\Code\User\settings.json
and whose Workspace Settings are stored at:
C:\TheLocationOfYourFolder\settings.json
This is the configuration when a single folder is added to a new installation of Visual Studio Code. Things get messy when we add a second (or greater) folder. That's because we are changing Visual Studio Code's User Settings and Workspace Settings to accommodate multiple folders. In a single-folder environment only two settings.json files are needed as listed above. But in a multi-folder environment a .vscode subfolder is created in each folder added to Explorer and a new file, "workspaces.json," is created to manage the multi-folder environment. The new "workspaces.json" file is created at:
c:\Users\%username%\AppData\Roaming\Code\Workspaces\%workspace_id%\workspaces.json
The "%workspaces_id%" is a folder with a unique all-number name.
In the Preferences right column there now appears three user setting options - User Settings, Workspace Settings, and Folder Settings. The function of User Settings remains the same as for a single-folder environment. However, the settings file behind the Workspace Settings has been changed from the settings.json file in the single folder's .vscode subfolder to the workspaces.json file located at the workspaces.json file path shown above. The settings.json file located in each folder's .vscode subfolder is now controlled by a third user setting, Folder Options. This is a drop-down selection list that allows for the management of each folder's settings.json file located in each folder's .vscode subfolder. Please note: the .vscode subfolder will not be created in newly-added explorer folders until the newly-added folder has been selected at least once in the folder options user setting.
Notice that the Explorer single folder name has bee changed to "UNTITLED (WORKSPACE)." This indicates the following:
The full functionality of Visual Studio Code workspaces is only realized when a workspace is saved as a file that can be reloaded as needed. This provides the capability to create unique multi-folder workspaces (e.g., projects) and save them as files for later use! To do this select menu File → Save Workspace As from the main menu and save the current workspace configuration as a unique workspace file. If you need to create a workspace "from scratch," first save your current workspace configuration (if needed) then right-click each Explorer folder name and click "Remove Folder from Workspace." When all folders have been removed from the workspace, add the folders you require for your new workspace. When you finish adding new folders, simply save the new workspace as a new workspace file.
An important note - Visual Studio Code doesn't "revert" to single-folder mode when only one folder remains in Explorer or when all folders have been removed from Explorer when creating a new workspace "from scratch." The multi-folder workspace configuration that utilizes three user preferences remains in effect. This means that unless you follow the instructions at the beginning of this post, Visual Studio Code can never be returned to a single-folder mode of operation - it will always remain in multi-folder workspace mode.
You can get attribute value by following way
$model = Mage::getResourceModel('catalog/product');
$attribute_value = $model->getAttributeRawValue($productId, 'attribute_code', $storeId);
Interfaces can not contain any implementation (including default values). You need to switch to abstract class.
Not in CSS 2 as far as I'm aware. CSS 3 has more robust selectors but is not consistently implemented across all browsers. Even with the improved selectors, I don't believe it will accomplish exactly what you've specified in your example.
Since you are using unix you can use a path like this.
/home/Production/modulename/logs/message.log
path should start with /
In code to load a resource in the executing assembly where my image Freq.png
was in the folder Icons
and defined as Resource
:
this.Icon = new BitmapImage(new Uri(@"pack://application:,,,/"
+ Assembly.GetExecutingAssembly().GetName().Name
+ ";component/"
+ "Icons/Freq.png", UriKind.Absolute));
I also made a function:
/// <summary>
/// Load a resource WPF-BitmapImage (png, bmp, ...) from embedded resource defined as 'Resource' not as 'Embedded resource'.
/// </summary>
/// <param name="pathInApplication">Path without starting slash</param>
/// <param name="assembly">Usually 'Assembly.GetExecutingAssembly()'. If not mentionned, I will use the calling assembly</param>
/// <returns></returns>
public static BitmapImage LoadBitmapFromResource(string pathInApplication, Assembly assembly = null)
{
if (assembly == null)
{
assembly = Assembly.GetCallingAssembly();
}
if (pathInApplication[0] == '/')
{
pathInApplication = pathInApplication.Substring(1);
}
return new BitmapImage(new Uri(@"pack://application:,,,/" + assembly.GetName().Name + ";component/" + pathInApplication, UriKind.Absolute));
}
Usage (assumption you put the function in a ResourceHelper class):
this.Icon = ResourceHelper.LoadBitmapFromResource("Icons/Freq.png");
Note: see MSDN Pack URIs in WPF:
pack://application:,,,/ReferencedAssembly;component/Subfolder/ResourceFile.xaml
Yet another node based simple command line server
https://github.com/greggman/servez-cli
Written partly in response to http-server having issues, particularly on windows.
Install node.js then
npm install -g servez
servez [options] [path]
With no path it serves the current folder.
By default it serves index.html
for folder paths if it exists. It serves a directory listing for folders otherwise. It also serves CORS headers. You can optionally turn on basic authentication with --username=somename --password=somepass
and you can serve https.
There're 3 ways to achieve this after conda
4.6. (The last method has the highest priority.)
Use sub-command conda config
to change the setting.
conda config --set auto_activate_base false
In fact, the former conda config
sub-command is changing configuration file .condarc
. We can modify .condarc
directly. Add following content into .condarc
under your home directory,
# auto_activate_base (bool)
# Automatically activate the base environment during shell
# initialization. for `conda init`
auto_activate_base: false
Set environment variable CONDA_AUTO_ACTIVATE_BASE
in the shell's init file. (.bashrc
for bash, .zshrc
for zsh)
CONDA_AUTO_ACTIVATE_BASE=false
To convert from the
condarc
file-based configuration parameter name to the environment variable parameter name, make the name all uppercase and prependCONDA_
. For example, conda’salways_yes
configuration parameter can be specified using aCONDA_ALWAYS_YES
environment variable.
The environment settings take precedence over corresponding settings in .condarc
file.
You could check whether the value of your selectOneMenu
component belongs to the list of subjects.
Namely:
public void subjectSelectionChanged() {
// Cancel if subject is manually written
if (!subjectList.contains(aktNachricht.subject)) { return; }
// Write your code here in case the user selected (or wrote) an item of the list
// ....
}
Supposedly subjectList
is a collection type, like ArrayList
. Of course here your code will run in case the user writes an item of your selectOneMenu
list.
You need to add C:\xampp\php
to your PATH Environment Variable
, Only after then you would be able to execute php
command line from outside php_home
.
You can use Angular $window
:
$window.location.href = '/index.html';
Example usage in a contoller:
(function () {
'use strict';
angular
.module('app')
.controller('LoginCtrl', LoginCtrl);
LoginCtrl.$inject = ['$window', 'loginSrv', 'notify'];
function LoginCtrl($window, loginSrv, notify) {
/* jshint validthis:true */
var vm = this;
vm.validateUser = function () {
loginSrv.validateLogin(vm.username, vm.password).then(function (data) {
if (data.isValidUser) {
$window.location.href = '/index.html';
}
else
alert('Login incorrect');
});
}
}
})();
Pylint message control is documented in the Pylint manual:
Is it possible to locally disable a particular message?
Yes, this feature has been added in Pylint 0.11. This may be done by adding
# pylint: disable=some-message,another-one
at the desired block level or at the end of the desired line of code.
You can use the message code or the symbolic names.
For example,
def test():
# Disable all the no-member violations in this function
# pylint: disable=no-member
...
global VAR # pylint: disable=global-statement
The manual also has further examples.
There is a wiki that documents all Pylint messages and their codes.
Immediately after you start a new activity, using startActivity
, make sure you call finish()
so that the current activity is not stacked behind the new one.
in my case it was just an intermittent issues it seems, didn't work for a few tries, then looked at https://registry.npmjs.org (webpage worked fine), tried again, tried again and then it worked.
