Another approach for same issue may help you Read and write file in private context of application
String NOTE = "note.txt";
private void writeToFile() {
try {
OutputStreamWriter out = new OutputStreamWriter(openFileOutput(
NOTES, 0));
out.write("testing");
out.close();
}
catch (Throwable t) {
Toast.makeText(this, "Exception: " + t.toString(), 2000).show();
}
}
private void ReadFromFile()
{
try {
InputStream in = openFileInput(NOTES);
if (in != null) {
InputStreamReader tmp = new InputStreamReader(in);
BufferedReader reader = new BufferedReader(tmp);
String str;
StringBuffer buf = new StringBuffer();
while ((str = reader.readLine()) != null) {
buf.append(str + "\n");
}
in.close();
String temp = "Not Working";
temp = buf.toString();
Toast.makeText(this, temp, Toast.LENGTH_SHORT).show();
}
} catch (java.io.FileNotFoundException e) {
// that's OK, we probably haven't created it yet
} catch (Throwable t) {
Toast.makeText(this, "Exception: " + t.toString(), 2000).show();
}
}
Named pipes and sockets are not functionally equivalent; sockets provide more features (they are bidirectional, for a start).
We cannot tell you which will perform better, but I strongly suspect it doesn't matter.
Unix domain sockets will do pretty much what tcp sockets will, but only on the local machine and with (perhaps a bit) lower overhead.
If a Unix socket isn't fast enough and you're transferring a lot of data, consider using shared memory between your client and server (which is a LOT more complicated to set up).
Unix and NT both have "Named pipes" but they are totally different in feature set.
To add to the end, use the +=
operator:
myArray += ["Craig"]
myArray += ["Jony", "Eddy"]
That operator is generally equivalent to the append(contentsOf:)
method. (And in really old Swift versions, could append single elements, not just other collections of the same element type.)
There's also insert(_:at:)
for inserting at any index.
If, say, you'd like a convenience function for inserting at the beginning, you could add it to the Array
class with an extension.
foreach ($basearr as &$row)
{
$row['value'] = $row['url'];
unset( $row['url'] );
}
unset($row);
The correct way of using post variables is
<?php
$department = $_POST['department'];
?>
Use single quotation(')
Maybe declaring a range might workout better for you.
// fill in the starting and ending range programmatically this is just an example.
string startRange = "A1";
string endRange = "A1";
Excel.Range currentRange = (Excel.Range)excelWorksheet.get_Range(startRange , endRange );
currentRange.Style.HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignLeft;
git rebase origin
means "rebase from the tracking branch of origin
", while git rebase origin/master
means "rebase from the branch master
of origin
"
You must have a tracking branch in ~/Desktop/test
, which means that git rebase origin
knows which branch of origin
to rebase with. If no tracking branch exists (in the case of ~/Desktop/fallstudie
), git doesn't know which branch of origin
it must take, and fails.
To fix this, you can make the branch track origin/master
with:
git branch --set-upstream-to=origin/master
Or, if master
isn't the currently checked-out branch:
git branch --set-upstream-to=origin/master master
What worked for me is to create a .launchd.conf
with the variables I needed:
setenv FOO barbaz
This file is read by launchd at login. You can add a variable 'on the fly' to the running launchd using:
launchctl setenv FOO barbaz`
In fact, .launchd.cond
simply contains launchctl commands.
Variables set this way seem to be present in GUI applications properly.
If you happen to be trying to set your LANG or LC_ variables in this way, and you happen to be using iTerm2, make sure you disable the 'Set locale variables automatically' setting under the Terminal tab of the Profile you're using. That seems to override launchd's environment variables, and in my case was setting a broken LC_CTYPE causing issues on remote servers (which got passed the variable).
(The environment.plist still seems to work on my Lion though. You can use the RCenvironment preference pane to maintain the file instead of manually editing it or required Xcode. Still seems to work on Lion, though it's last update is from the Snow Leopard era. Makes it my personally preferred method.)
Does this do what you want?
.childRightCol, .childLeftCol
{
display: inline-block;
width: 50%;
margin: 0;
padding: 0;
vertical-align: top;
}
It is a build target that is not a filename.
For old Python (tested on 2.4) the top solution points the way. You can do this:
import string
def try_interp():
d = 1
f = 1.1
s = "s"
print string.Template("d: $d f: $f s: $s").substitute(**locals())
try_interp()
And you get
d: 1 f: 1.1 s: s
You want awk
.
This would be a quick and dirty hack:
awk -F "\"" '{print $2}' /tmp/file.txt

In addition, you can change Eclipse shortcut in Windows -> Preferences -> General -> Keys
You must use a .ts
file - e.g. test.ts
to get Typescript validation, intellisense typing
of vars, return types, as well as "typed" error checking (e.g. passing a string
to a method that expects an number
param will error out).
It will be transpiled into (standard) .js
via tsc
.
Clarification needed based on down-votes, very helpful comments and other answers.
types
Yes, you can do type
checking in VS Code in .js
files with @ts-check
- as shown in the animation
What I originally was referring to for Typescript types
is something like this in .ts
which isn't quite the same thing:
hello-world.ts
function hello(str: string): string {
return 1;
}
function foo(str:string):void{
console.log(str);
}
This will not compile. Error: Type "1" is not assignable to String
if you tried this syntax in a Javascript hello-world.js
file:
//@ts-check
function hello(str: string): string {
return 1;
}
function foo(str:string):void{
console.log(str);
}
The error message referenced by OP is shown: [js] 'types' can only be used in a .ts file
If there's something I missed that covers this as well as the OP's context, please add. Let's all learn.
INSERT
statements that use VALUES
syntax can insert multiple rows. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas.
Example:
INSERT INTO tbl_name (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9);
The particular case of RubyGems (the command line tool) is that it requires to bundle inside of its code the trust certificates, which allow RubyGems to establish a connection with the servers even when base operating system is unable to verify the identity of them.
Up until a few months ago, this certificate was provided by one CA, but newer certificate is provided by a different one.
Because of this, existing installations of RubyGems would have to been updated before the switch of the certificate and give enough time for the change to spread (and people to update)
Anyone can find his solution by following the simple steps given in the link below
using System.Security.Cryptography;
public static byte[] GetHash(string inputString)
{
using (HashAlgorithm algorithm = SHA256.Create())
return algorithm.ComputeHash(Encoding.UTF8.GetBytes(inputString));
}
public static string GetHashString(string inputString)
{
StringBuilder sb = new StringBuilder();
foreach (byte b in GetHash(inputString))
sb.Append(b.ToString("X2"));
return sb.ToString();
}
Additional Notes
Simply sleeping for 10 seconds or using threading.Timer(10,foo)
will result in start time drift. (You may not care about this, or it may be a significant source of problems depending on your exact situation.) There can be two causes for this - inaccuracies in the wake up time of your thread or execution time for your function.
You can see some results at the end of this post, but first an example of how to fix it. You need to track when your function should next be called as opposed to when it actually got called and account for the difference.
Here's a version that drifts slightly:
import datetime, threading
def foo():
print datetime.datetime.now()
threading.Timer(1, foo).start()
foo()
Its output looks like this:
2013-08-12 13:05:36.483580
2013-08-12 13:05:37.484931
2013-08-12 13:05:38.485505
2013-08-12 13:05:39.486945
2013-08-12 13:05:40.488386
2013-08-12 13:05:41.489819
2013-08-12 13:05:42.491202
2013-08-12 13:05:43.492486
2013-08-12 13:05:44.493865
2013-08-12 13:05:45.494987
2013-08-12 13:05:46.496479
2013-08-12 13:05:47.497824
2013-08-12 13:05:48.499286
2013-08-12 13:05:49.500232
You can see that the sub-second count is constantly increasing and thus, the start time is "drifting".
This is code that correctly accounts for drift:
import datetime, threading, time
next_call = time.time()
def foo():
global next_call
print datetime.datetime.now()
next_call = next_call+1
threading.Timer( next_call - time.time(), foo ).start()
foo()
Its output looks like this:
2013-08-12 13:21:45.292565
2013-08-12 13:21:47.293000
2013-08-12 13:21:48.293939
2013-08-12 13:21:49.293327
2013-08-12 13:21:50.293883
2013-08-12 13:21:51.293070
2013-08-12 13:21:52.293393
Here you can see that there is no longer any increase in the sub-second times.
If your events are occurring really frequently you may want to run the timer in a single thread, rather than starting a new thread for each event. While accounting for drift this would look like:
import datetime, threading, time
def foo():
next_call = time.time()
while True:
print datetime.datetime.now()
next_call = next_call+1;
time.sleep(next_call - time.time())
timerThread = threading.Thread(target=foo)
timerThread.start()
However your application will not exit normally, you'll need to kill the timer thread. If you want to exit normally when your application is done, without manually killing the thread, you should use
timerThread = threading.Thread(target=foo)
timerThread.daemon = True
timerThread.start()
The answers on here are specific to using the custom UI Editor. I spent some time creating the interface without that wonderful program, so I am documenting the solution here to help anyone else decide if they need that custom UI editor or not.
I came across the following microsoft help webpage - https://msdn.microsoft.com/en-us/library/office/ff861787.aspx. This shows how to set up the interface manually, but I had some trouble when pointing to my custom add-in code.
To get the buttons to work with your custom macros, setup the macro in your .xlam subs to be called as described in this SO answer - Calling an excel macro from the ribbon. Basically, you'll need to add that "control As IRibbonControl" paramter to any module pointed from your ribbon xml. Also, your ribbon xml should have the onAction="myaddin!mymodule.mysub" syntax to properly call any modules loaded by the add in.
Using those instructions I was able to create an excel add in (.xlam file) that has a custom tab loaded when my VBA gets loaded into Excel along with the add in. The buttons execute code from the add in and the custom tab uninstalls when I remove the add in.
An elegant RxJava/Kotlin solution is to use Completable.fromCallable
, which will give you an Observable which does not return a value, but can observed and subscribed on a different thread.
public Completable insert(Event event) {
return Completable.fromCallable(new Callable<Void>() {
@Override
public Void call() throws Exception {
return database.eventDao().insert(event)
}
}
}
Or in Kotlin:
fun insert(event: Event) : Completable = Completable.fromCallable {
database.eventDao().insert(event)
}
You can the observe and subscribe as you would usually:
dataManager.insert(event)
.subscribeOn(scheduler)
.observeOn(AndroidSchedulers.mainThread())
.subscribe(...)
In addition to axtavt's answer, don't forget you can inject Entity Manager in your custom implementation if you need it to build your queries:
public class AccountRepositoryImpl implements AccountRepositoryCustom {
@PersistenceContext
private EntityManager em;
public void customMethod() {
...
em.createQuery(yourCriteria);
...
}
}
This code works for me: I set values whit an INSERT and get the LAST_INSERT_ID() of this value whit a SELECT; I use java NetBeans 8.1, MySql and java.JDBC.driver
try {
String Query = "INSERT INTO `stock`(`stock`, `min_stock`,
`id_stock`) VALUES ("
+ "\"" + p.get_Stock().getStock() + "\", "
+ "\"" + p.get_Stock().getStockMinimo() + "\","
+ "" + "null" + ")";
Statement st = miConexion.createStatement();
st.executeUpdate(Query);
java.sql.ResultSet rs;
rs = st.executeQuery("Select LAST_INSERT_ID() from stock limit 1");
rs.next(); //para posicionar el puntero en la primer fila
ultimo_id = rs.getInt("LAST_INSERT_ID()");
} catch (SqlException ex) { ex.printTrace;}
In my opinion the answer is wrong! He asked for event.preventDefault();
when you simply return false; it calls event.preventDefault();
AND event.stopPropagation();
as well!
You can solve it by this:
<a href="#" onclick="callmymethod(event, 24)">Call</a>
function callmymethod(e, myVal){
//doing custom things with myVal
//here I want to prevent default
e = e || window.event;
e.preventDefault();
}
I mean, why not a p/invoke method?
using System;
using System.IO;
using System.Runtime.InteropServices;
using System.Text;
public class AppInfo
{
[DllImport("kernel32.dll", CharSet = CharSet.Auto, ExactSpelling = false)]
private static extern int GetModuleFileName(HandleRef hModule, StringBuilder buffer, int length);
private static HandleRef NullHandleRef = new HandleRef(null, IntPtr.Zero);
public static string StartupPath
{
get
{
StringBuilder stringBuilder = new StringBuilder(260);
GetModuleFileName(NullHandleRef, stringBuilder, stringBuilder.Capacity);
return Path.GetDirectoryName(stringBuilder.ToString());
}
}
}
You would use it just like the Application.StartupPath:
Console.WriteLine("The path to this executable is: " + AppInfo.StartupPath + "\\" + System.Diagnostics.Process.GetCurrentProcess().ProcessName + ".exe");
When I did just a remove the option remained in the ddl on the view, but was gone in the html (if u inspect the page)
$("#ddlSelectList option[value='2']").remove(); //removes the option with value = 2
$('#ddlSelectList').val('').trigger('chosen:updated'); //refreshes the drop down list
Your syntax is incorrect, you should either specify a hash:
hash = {abc: true, def: true, ghi: true};
Or an array:
arr = ['abc','def','ghi'];
You can effectively remove an item from a hash by simply setting it to null:
hash['def'] = null;
hash.def = null;
Or removing it entirely:
delete hash.def;
To remove an item from an array you have to iterate through each item and find the one you want (there may be duplicates). You could use array searching and splicing methods:
arr.splice(arr.indexOf("def"), 1);
This finds the first index of "def" and then removes it from the array with splice. However I would recommend .filter() because it gives you more control:
arr.filter(function(item) { return item !== 'def'; });
This will create a new array with only elements that are not 'def'.
It is important to note that arr.filter() will return a new array, while arr.splice will modify the original array and return the removed elements. These can both be useful, depending on what you want to do with the items.
For your case solution is :
php artisan cache:clear
php artisan route:cache
Optimizing Route Loading is a must on production :
If you are building a large application with many routes, you should make sure that you are running the route:cache Artisan command during your deployment process:
php artisan route:cache
This command reduces all of your route registrations into a single method call within a cached file, improving the performance of route registration when registering hundreds of routes.
Since this feature uses PHP serialization, you may only cache the routes for applications that exclusively use controller based routes. PHP is not able to serialize Closures.
Laravel 5 clear cache from route, view, config and all cache data from application
I would like to share my experience and solution. when i was working on my laravel e commerce website with gitlab. I was fetching one issue suddenly my view cache with error during development. i did try lot to refresh and something other but i can't see any more change in my view, but at last I did resolve my problem using laravel command so, let's see i added several command for clear cache from view, route, config etc.
Reoptimized class loader:
php artisan optimize
Clear Cache facade value:
php artisan cache:clear
Clear Route cache:
php artisan route:cache
Clear View cache:
php artisan view:clear
Clear Config cache:
php artisan config:cache
When you run the Windows Command Prompt, and type in python
, it starts the Python interpreter.
Typing it again tries to interpret python
as a variable, which doesn't exist and thus won't work:
Microsoft Windows [Version 6.1.7601]
Copyright (c) 2009 Microsoft Corporation. All rights reserved.
C:\Users\USER>python
Python 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'python' is not defined
>>> print("interpreter has started")
interpreter has started
>>> quit() # leave the interpreter, and go back to the command line
C:\Users\USER>
If you're not doing this from the command line, and instead running the Python interpreter (python.exe or IDLE's shell) directly, you are not in the Windows Command Line, and python
is interpreted as a variable, which you have not defined.
I want to add a point that you can also (and should if what you are writing is complex) add a test variable to rollback if you are in test mode. Then you can execute the whole thing at once. Often I also add code to see the before and after results of various operations especially if it is a complex script.
Example below:
USE AdventureWorks;
GO
DECLARE @TEST INT = 1--1 is test mode, use zero when you are ready to execute
BEGIN TRANSACTION;
BEGIN TRY
IF @TEST= 1
BEGIN
SELECT *FROM Production.Product
WHERE ProductID = 980;
END
-- Generate a constraint violation error.
DELETE FROM Production.Product
WHERE ProductID = 980;
IF @TEST= 1
BEGIN
SELECT *FROM Production.Product
WHERE ProductID = 980;
IF @@TRANCOUNT > 0
ROLLBACK TRANSACTION;
END
END TRY
BEGIN CATCH
SELECT
ERROR_NUMBER() AS ErrorNumber
,ERROR_SEVERITY() AS ErrorSeverity
,ERROR_STATE() AS ErrorState
,ERROR_PROCEDURE() AS ErrorProcedure
,ERROR_LINE() AS ErrorLine
,ERROR_MESSAGE() AS ErrorMessage;
IF @@TRANCOUNT > 0
ROLLBACK TRANSACTION;
END CATCH;
IF @@TRANCOUNT > 0 AND @TEST = 0
COMMIT TRANSACTION;
GO
Simply setting the Network Setting to bridged did the trick for me.
Your IP will change when you do this. However, in my case it didn't change immediately. ifconfig

If you want to access event object as well as data passed, you have to pass event

both as parameters, like following:
HTML
<input type="number" v-on:input="addToCart($event, ticket.id)" min="0" placeholder="0">
Javascript
methods: {
addToCart: function (event, id) {
// use event here as well as id
console.log('In addToCart')
console.log(id)
}
}
See working fiddle: https://jsfiddle.net/nee5nszL/
In case you are using vue-router, you may have to use $event in your v-on:input
method like following:
<input type="number" v-on:input="addToCart($event, num)" min="0" placeholder="0">

In a nutshell :
-> Git Merge: It will simply merge your local changes and remote changes, and that will create another commit history record
-> Git Rebase: It will put your changes above all new remote changes, and rewrite commit history, so your commit history will be much cleaner than git merge. Rebase is a destructive operation. That means, if you do not apply it correctly, you could lose committed work and/or break the consistency of other developer's repositories.
if you have
<span class="label label-default">New</span>
just add the style="font-size:XXpx;", ej.
<span class="label label-default" style="font-size:15px;">New</span>
Declare an output cursor variable to the inner sp :
@c CURSOR VARYING OUTPUT
Then declare a cursor c to the select you want to return. Then open the cursor. Then set the reference:
DECLARE c CURSOR LOCAL FAST_FORWARD READ_ONLY FOR
SELECT ...
OPEN c
SET @c = c
DO NOT close or reallocate.
Now call the inner sp from the outer one supplying a cursor parameter like:
exec sp_abc a,b,c,, @cOUT OUTPUT
Once the inner sp executes, your @cOUT
is ready to fetch. Loop and then close and deallocate.
Watch for filenames in italic
Note that, the file name on the tab is formatted in italic if it has been opened in Preview Mode
.
Quickly take a file out of Preview Mode
To keep the file always available in VSCode editor (that is, to take it out of Preview Mode
into normal mode), you can double-click on the tab. Then, you will notice the name becomes non-italic.
Feature or bug?
I believe Preview Mode is helpful especially when you have limited screen space and need to check many files.

This is the most reliable way when you are passing integer kind of value or other short parameters. More advance in this method if you are using any special characters in the value while passing it through query string, you must encode the value before passing it to next page. So our code snippet of will be something like this:
FirstForm.aspx.cs
Response.Redirect("SecondForm.aspx?Parameter=" + Server.UrlEncode(TextBox1.Text));
SecondForm.aspx.cs
TextBox1.Text = Server.UrlDecode(Request.QueryString["Parameter"].ToString());
URL Encoding
2. Passing value through context object
Passing value through context object is another widely used method.
FirstForm.aspx.cs
TextBox1.Text = this.Context.Items["Parameter"].ToString();
SecondForm.aspx.cs
this.Context.Items["Parameter"] = TextBox1.Text;
Server.Transfer("SecondForm.aspx", true);
Note that we are navigating to another page using Server.Transfer instead of Response.Redirect.Some of us also use Session object to pass values. In that method, value is store in Session object and then later pulled out from Session object in Second page.
3. Posting form to another page instead of PostBack
Third method of passing value by posting page to another form. Here is the example of that:
FirstForm.aspx.cs
private void Page_Load(object sender, System.EventArgs e)
{
buttonSubmit.Attributes.Add("onclick", "return PostPage();");
}
And we create a javascript function to post the form.
SecondForm.aspx.cs
function PostPage()
{
document.Form1.action = "SecondForm.aspx";
document.Form1.method = "POST";
document.Form1.submit();
}
TextBox1.Text = Request.Form["TextBox1"].ToString();
Here we are posting the form to another page instead of itself. You might get viewstate invalid or error in second page using this method. To handle this error is to put EnableViewStateMac=false
4. Another method is by adding PostBackURL property of control for cross page post back
In ASP.NET 2.0, Microsoft has solved this problem by adding PostBackURL property of control for cross page post back. Implementation is a matter of setting one property of control and you are done.
FirstForm.aspx.cs
<asp:Button id=buttonPassValue style=”Z-INDEX: 102" runat=”server” Text=”Button” PostBackUrl=”~/SecondForm.aspx”></asp:Button>
SecondForm.aspx.cs
TextBox1.Text = Request.Form["TextBox1"].ToString();
In above example, we are assigning PostBackUrl property of the button we can determine the page to which it will post instead of itself. In next page, we can access all controls of the previous page using Request object.
You can also use PreviousPage class to access controls of previous page instead of using classic Request object.
SecondForm.aspx
TextBox textBoxTemp = (TextBox) PreviousPage.FindControl(“TextBox1");
TextBox1.Text = textBoxTemp.Text;
As you have noticed, this is also a simple and clean implementation of passing value between pages.

HAPPY CODING!
I did this in the web.config file. I added to Sobhan's answer, thanks btw.
<connectionStrings>
<add name="listdb" connectionString="Data Source=|DataDirectory|\db\listdb.sdf"/>
</connectionStrings>
Where "db" becomes my database directory instead of "App_Data" directory.
And opened normally with:
var db = Database.Open("listdb");
In drawable I use this xml code to define the border and background:
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<stroke android:width="4dp" android:color="#D8FDFB" />
<padding android:left="7dp" android:top="7dp"
android:right="7dp" android:bottom="7dp" />
<corners android:radius="4dp" />
<solid android:color="#f0600000"/>
</shape>
None of the answers here worked for me. I fixed it by putting my PHP as the very very first thing in the page.
Like other headers, cookies must be sent before any output from your script (this is a protocol restriction). This requires that you place calls to this function prior to any output, including and tags as well as any whitespace.
Similar to previous answer:
<script type="text/javascript">
var wait = false;
$(function(){
console.log('Loaded...');
loadPost(5);
});
$(window).scroll(function(){
if($(window).scrollTop() >= $(document).height() - $(window).height()-100){
// Get last item
var last = $('.post_id:last-of-type').val();
loadPost(1,last);
}
});
function loadPost(qty,offset){
if(wait !== true){
wait = true;
var data = {
items:qty,
oset:offset
}
$.ajax({
url:"api.php",
type:"POST",
dataType:"json",
data:data,
success:function(data){
//var d = JSON.parse(data);
console.log(data);
$.each(data.content, function(index, value){
$('#content').append('<input class="post_id" type="hidden" value="'+value.id+'">')
$('#content').append('<h2>'+value.id+'</h2>');
$('#content').append(value.content+'<hr>');
$('#content').append('<h3>'+value.date+'</h3>');
});
wait = false;
}
});
}
}
</script>
Try:
-webkit-transition: all .2s linear, background-position 0;
This worked for me on something similar..
Set alias: (based on the top answer)
git config --global alias.track-all-branches '!git fetch --all && for remote in `git branch -r`; do git branch --track ${remote#origin/} $remote; done && git fetch --all'
Now to track all the branches:
git track-all-branches
var $select = $(document.getElementById("selectTagName"));
var selectize = $select[0].selectize;
selectize.setValue(selectize.search("My Default Value").items[0]);
Use #propagate() method. Sample non-Guava implementation from Java 8 Blog by Sam Beran:
public class Throwables {
public interface ExceptionWrapper<E> {
E wrap(Exception e);
}
public static <T> T propagate(Callable<T> callable) throws RuntimeException {
return propagate(callable, RuntimeException::new);
}
public static <T, E extends Throwable> T propagate(Callable<T> callable, ExceptionWrapper<E> wrapper) throws E {
try {
return callable.call();
} catch (RuntimeException e) {
throw e;
} catch (Exception e) {
throw wrapper.wrap(e);
}
}
}

if you are using extracted tomcat then,
startup.sh
and shutdown.sh
are two script located in TOMCAT/bin/ to start and shutdown tomcat, You could use that
if tomcat is installed then
/etc/init.d/tomcat5.5 start
/etc/init.d/tomcat5.5 stop
/etc/init.d/tomcat5.5 restart
Recently I learned of the following syntax:
DELETE (SELECT *
FROM productfilters pf
INNER JOIN product pr
ON pf.productid = pr.id
WHERE pf.id >= 200
AND pr.NAME = 'MARK')
I think it looks much cleaner then other proposed code.
One more thing - if You edited the shell script in some Windows text editor, which produces the \r\n
line-endings, cygwin's bash wouldn't accept those \r
. Just run dos2unix testit.sh
before executing the script:
C:\cygwin\bin\dos2unix testit.sh
C:\cygwin\bin\bash testit.sh
I recognize that the answer works and has been accepted but there is a much cleaner way to write that query. Tested on mysql and postgres.

This won't get rid of the close button, but it will stop someone closing the window.
Put this in your code behind file:
protected override void OnClosing(CancelEventArgs e)
{
base.OnClosing(e);
e.Cancel = true;
}
Facelets is a XML based view technology. The &
is a special character in XML representing the start of an entity like &
which ends with the ;
character. You'd need to either escape it, which is ugly:
rendered="#{beanA.prompt == true && beanB.currentBase != null}"
or to use the and
keyword instead, which is preferred as to readability and maintainability:
rendered="#{beanA.prompt == true and beanB.currentBase != null}"
Unrelated to the concrete problem, comparing booleans with booleans makes little sense when the expression expects a boolean outcome already. I'd get rid of == true
:
rendered="#{beanA.prompt and beanB.currentBase != null}"
So there's are multiple answers and requires a all content at once place so I'm adding this answer:
If you're using AutoLayout, by setting this only should work for you:
tableView.alwaysBounceVertical = false
Just find this option and untick
"Bounce Vertically
" option.
Here's the reference:
If you're not using AutoLayout:
override func viewDidLayoutSubviews() {
// Enable scrolling based on content height
tableView.isScrollEnabled = tableView.contentSize.height > tableView.frame.size.height
}
You can definitely use num1 = (20 if someBoolValue else num1) if you want.
Try:

For v1.19.0 for JQuery Validation I found this one line of code worked for me:
$('.field-validation-error').removeClass('field-validation-error').addClass('field-validation-valid').html('');
In effect making the field appear valid to the user but when they click submit again the validation re-fires.
Try this php code.

$_SERVER['HTTP_CLIENT_IP'] = $_SERVER["HTTP_CF_CONNECTING_IP"];
}
$client = @$_SERVER['HTTP_CLIENT_IP'];
$forward = @$_SERVER['HTTP_X_FORWARDED_FOR'];
$remote = $_SERVER['REMOTE_ADDR'];
if(filter_var($client, FILTER_VALIDATE_IP))
{
$ip = $client;
}
elseif(filter_var($forward, FILTER_VALIDATE_IP))
{
$ip = $forward;
}
else
{

return $ip;
}
$user_ip = getUserIP();
echo $user_ip; // Output IP address [Ex: 177.87.193.134]

Implementation of seconds/minutes/hours, which are rails methods. Note that implicit returns aren't needed, but they look cleaner, so I prefer them. I'm not sure Rails even has .days or if it goes further, but these are the ones I need.
class Integer
def seconds
return self
end
def minutes
return self * 60
end
def hours
return self * 3600
end
def days
return self * 86400
end
end
After this, you can do:
sleep 5.seconds
to sleep for 5 seconds. You can do sleep 5.minutes
to sleep for 5 min. You can do sleep 5.hours
to sleep for 5 hours. And finally, you can do sleep 5.days
to sleep for 5 days... You can add any method that return the value of self * (amount of seconds in that timeframe).
As an exercise, try implementing it for months!

For me I removed whole data
folder from xampp\mysql\
and pasted data
folder of previous one here which solved my problem...
This should work (adapted from https://stackoverflow.com/a/8285722/388902).
var ctrl_down = false;
var ctrl_key = 17;
var s_key = 83;
$(document).keydown(function(e) {
if (e.keyCode == ctrl_key) ctrl_down = true;
}).keyup(function(e) {
if (e.keyCode == ctrl_key) ctrl_down = false;
});
$(document).keydown(function(e) {
if (ctrl_down && (e.keyCode == s_key)) {
alert('Ctrl-s pressed');
// Your code
return false;
}
});

Since I wrote my prior answer, I have formulated a new definition of the declarative property which is quoted below. I have also defined imperative programming as the dual property.
This definition is superior to the one I provided in my prior answer, because it is succinct and it is more general. But it may be more difficult to grok, because the implication of the incompleteness theorems applicable to programming and life in general are difficult for humans to wrap their mind around.
The quoted explanation of the definition discusses the role pure functional programming plays in declarative programming.
Declarative vs. Imperative
The declarative property is weird, obtuse, and difficult to capture in a technically precise definition that remains general and not ambiguous, because it is a naive notion that we can declare the meaning (a.k.a semantics) of the program without incurring unintended side effects. There is an inherent tension between expression of meaning and avoidance of unintended effects, and this tension actually derives from the incompleteness theorems of programming and our universe.
It is oversimplification, technically imprecise, and often ambiguous to define declarative as “what to do” and imperative as “how to do”. An ambiguous case is the “what” is the “how” in a program that outputs a program— a compiler.
Evidently the unbounded recursion that makes a language Turing complete, is also analogously in the semantics— not only in the syntactical structure of evaluation (a.k.a. operational semantics). This is logically an example analogous to Gödel's theorem— “any complete system of axioms is also inconsistent”. Ponder the contradictory weirdness of that quote! It is also an example that demonstrates how the expression of semantics does not have a provable bound, thus we can't prove2 that a program (and analogously its semantics) halt a.k.a. the Halting theorem.
The incompleteness theorems derive from the fundamental nature of our universe, which as stated in the Second Law of Thermodynamics is “the entropy (a.k.a. the # of independent possibilities) is trending to maximum forever”. The coding and design of a program is never finished— it's alive!— because it attempts to address a real world need, and the semantics of the real world are always changing and trending to more possibilities. Humans never stop discovering new things (including errors in programs ;-).
To precisely and technically capture this aforementioned desired notion within this weird universe that has no edge (ponder that! there is no “outside” of our universe), requires a terse but deceptively-not-simple definition which will sound incorrect until it is explained deeply.
Definition:
The declarative property is where there can exist only one possible set of statements that can express each specific modular semantic.
The imperative property3 is the dual, where semantics are inconsistent under composition and/or can be expressed with variations of sets of statements.
This definition of declarative is distinctively local in semantic scope, meaning that it requires that a modular semantic maintain its consistent meaning regardless where and how it's instantiated and employed in global scope. Thus each declarative modular semantic should be intrinsically orthogonal to all possible others— and not an impossible (due to incompleteness theorems) global algorithm or model for witnessing consistency, which is also the point of “More Is Not Always Better” by Robert Harper, Professor of Computer Science at Carnegie Mellon University, one of the designers of Standard ML.
Examples of these modular declarative semantics include category theory functors e.g. the
Applicative
, nominal typing, namespaces, named fields, and w.r.t. to operational level of semantics then pure functional programming.Thus well designed declarative languages can more clearly express meaning, albeit with some loss of generality in what can be expressed, yet a gain in what can be expressed with intrinsic consistency.
An example of the aforementioned definition is the set of formulas in the cells of a spreadsheet program— which are not expected to give the same meaning when moved to different column and row cells, i.e. cell identifiers changed. The cell identifiers are part of and not superfluous to the intended meaning. So each spreadsheet result is unique w.r.t. to the cell identifiers in a set of formulas. The consistent modular semantic in this case is use of cell identifiers as the input and output of pure functions for cells formulas (see below).
Hyper Text Markup Language a.k.a. HTML— the language for static web pages— is an example of a highly (but not perfectly3) declarative language that (at least before HTML 5) had no capability to express dynamic behavior. HTML is perhaps the easiest language to learn. For dynamic behavior, an imperative scripting language such as JavaScript was usually combined with HTML. HTML without JavaScript fits the declarative definition because each nominal type (i.e. the tags) maintains its consistent meaning under composition within the rules of the syntax.
A competing definition for declarative is the commutative and idempotent properties of the semantic statements, i.e. that statements can be reordered and duplicated without changing the meaning. For example, statements assigning values to named fields can be reordered and duplicated without changed the meaning of the program, if those names are modular w.r.t. to any implied order. Names sometimes imply an order, e.g. cell identifiers include their column and row position— moving a total on spreadsheet changes its meaning. Otherwise, these properties implicitly require global consistency of semantics. It is generally impossible to design the semantics of statements so they remain consistent if randomly ordered or duplicated, because order and duplication are intrinsic to semantics. For example, the statements “Foo exists” (or construction) and “Foo does not exist” (and destruction). If one considers random inconsistency endemical of the intended semantics, then one accepts this definition as general enough for the declarative property. In essence this definition is vacuous as a generalized definition because it attempts to make consistency orthogonal to semantics, i.e. to defy the fact that the universe of semantics is dynamically unbounded and can't be captured in a global coherence paradigm.
Requiring the commutative and idempotent properties for the (structural evaluation order of the) lower-level operational semantics converts operational semantics to a declarative localized modular semantic, e.g. pure functional programming (including recursion instead of imperative loops). Then the operational order of the implementation details do not impact (i.e. spread globally into) the consistency of the higher-level semantics. For example, the order of evaluation of (and theoretically also the duplication of) the spreadsheet formulas doesn't matter because the outputs are not copied to the inputs until after all outputs have been computed, i.e. analogous to pure functions.
C, Java, C++, C#, PHP, and JavaScript aren't particularly declarative. Copute's syntax and Python's syntax are more declaratively coupled to intended results, i.e. consistent syntactical semantics that eliminate the extraneous so one can readily comprehend code after they've forgotten it. Copute and Haskell enforce determinism of the operational semantics and encourage “don't repeat yourself” (DRY), because they only allow the pure functional paradigm.
2 Even where we can prove the semantics of a program, e.g. with the language Coq, this is limited to the semantics that are expressed in the typing, and typing can never capture all of the semantics of a program— not even for languages that are not Turing complete, e.g. with HTML+CSS it is possible to express inconsistent combinations which thus have undefined semantics.
3 Many explanations incorrectly claim that only imperative programming has syntactically ordered statements. I clarified this confusion between imperative and functional programming. For example, the order of HTML statements does not reduce the consistency of their meaning.
Edit: I posted the following comment to Robert Harper's blog:
in functional programming ... the range of variation of a variable is a type
Depending on how one distinguishes functional from imperative programming, your ‘assignable’ in an imperative program also may have a type placing a bound on its variability.
The only non-muddled definition I currently appreciate for functional programming is a) functions as first-class objects and types, b) preference for recursion over loops, and/or c) pure functions— i.e. those functions which do not impact the desired semantics of the program when memoized (thus perfectly pure functional programming doesn't exist in a general purpose denotational semantics due to impacts of operational semantics, e.g. memory allocation).
The idempotent property of a pure function means the function call on its variables can be substituted by its value, which is not generally the case for the arguments of an imperative procedure. Pure functions seem to be declarative w.r.t. to the uncomposed state transitions between the input and result types.
But the composition of pure functions does not maintain any such consistency, because it is possible to model a side-effect (global state) imperative process in a pure functional programming language, e.g. Haskell's IOMonad and moreover it is entirely impossible to prevent doing such in any Turing complete pure functional programming language.
As I wrote in 2012 which seems to the similar consensus of comments in your recent blog, that declarative programming is an attempt to capture the notion that the intended semantics are never opaque. Examples of opaque semantics are dependence on order, dependence on erasure of higher-level semantics at the operational semantics layer (e.g. casts are not conversions and reified generics limit higher-level semantics), and dependence on variable values which can not be checked (proved correct) by the programming language.
Thus I have concluded that only non-Turing complete languages can be declarative.
Thus one unambiguous and distinct attribute of a declarative language could be that its output can be proven to obey some enumerable set of generative rules. For example, for any specific HTML program (ignoring differences in the ways interpreters diverge) that is not scripted (i.e. is not Turing complete) then its output variability can be enumerable. Or more succinctly an HTML program is a pure function of its variability. Ditto a spreadsheet program is a pure function of its input variables.
So it seems to me that declarative languages are the antithesis of unbounded recursion, i.e. per Gödel's second incompleteness theorem self-referential theorems can't be proven.
Lesie Lamport wrote a fairytale about how Euclid might have worked around Gödel's incompleteness theorems applied to math proofs in the programming language context by to congruence between types and logic (Curry-Howard correspondence, etc).
You could embed the ''
default in your regex by adding |$
:
>>> re.findall('\d+|$', 'aa33bbb44')[0]
'33'
>>> re.findall('\d+|$', 'aazzzbbb')[0]
''
>>> re.findall('\d+|$', '')[0]
''
Also works with re.search
pointed out by others:
>>> re.search('\d+|$', 'aa33bbb44').group()
'33'
>>> re.search('\d+|$', 'aazzzbbb').group()
''
>>> re.search('\d+|$', '').group()
''
You can simply write
string time = dateTimeObect.ToString("HH:mm");
In my case it was $NODE_PATH missing:
NODE="/home/ubuntu/local/node" #here your user account after home
NODE_PATH="/usr/local/lib/node_modules"
PATH="$PATH:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:$NODE/bin:$NODE/lib/node_modules"
To check just echo $NODE_PATH
empty means it is not set. Add them to .bashrc is recommended.
use absolute path where the image actually exists (e.g) '/home/artitra/pictures/filename.jpg'
or create static folder inside your project directory like this
| templates
- static/
- images/
- yourimagename.jpg
then do this
app = Flask(__name__, static_url_path='/static')
then you can access your image like this in index.html
src ="/static/images/yourimage.jpg"
in img tag
I had the same problem but solved it with a switch statement switch(a value you are switching on) { case 1: the code you want to happen; case 2: the code you want to happen; default: return a value }
foreach makes the intention of your code clearer and that is normally preferred over a very minor speed improvement - if any.
Whenever I see an indexed loop I have to parse it a little longer to make sure it does what I think it does E.g. Does it start from zero, does it include or exclude the end point etc.?
Most of my time seems to be spent reading code (that I wrote or someone else wrote) and clarity is almost always more important than performance. Its easy to dismiss performance these days because Hotspot does such an amazing job.
Try with:
@Scheduled(cron = "0 1 1 * * ?")
Below you can find the example patterns from the spring forum:
* "0 0 * * * *" = the top of every hour of every day.
* "*/10 * * * * *" = every ten seconds.
* "0 0 8-10 * * *" = 8, 9 and 10 o'clock of every day.
* "0 0 8,10 * * *" = 8 and 10 o'clock of every day.
* "0 0/30 8-10 * * *" = 8:00, 8:30, 9:00, 9:30 and 10 o'clock every day.
* "0 0 9-17 * * MON-FRI" = on the hour nine-to-five weekdays
* "0 0 0 25 12 ?" = every Christmas Day at midnight
Cron expression is represented by six fields:
second, minute, hour, day of month, month, day(s) of week
(*)
means match any
*/X
means "every X"
?
("no specific value") - useful when you need to specify something in one of the two fields in which the character is allowed, but not the other. For example, if I want my trigger to fire on a particular day of the month (say, the 10th), but I don't care what day of the week that happens to be, I would put "10" in the day-of-month field and "?" in the day-of-week field.

As Oscar Wilde said
Consistency is the last refuge of the unimaginative.
R is more of an evolved rather than designed language, so these things happen. names()
and colnames()
work on a data.frame
but names()
does not work on a matrix:
R> DF <- data.frame(foo=1:3, bar=LETTERS[1:3])
R> names(DF)
[1] "foo" "bar"

As discussed, there are several ways to search:
/pattern
?pattern
* (and g*, which I sometimes use in macros)
# (and g#)
plus, navigating prev/next with N and n.
You can also edit/recall your search history by pulling up the search prompt with /
and then cycle with C-p
/C-n
. Even more useful is q/
, which takes you to a window where you can navigate the search history.
Also for consideration is the all-important 'hlsearch'
(type :hls
to enable). This makes it much easier to find multiple instances of your pattern. You might even want make your matches extra bright with something like:
hi Search ctermfg=yellow ctermbg=red guifg=...
But then you might go crazy with constant yellow matches all over your screen. So you’ll often find yourself using :noh
. This is so common that a mapping is in order:
nmap <leader>z :noh<CR>
I easily remember this one as z
since I used to constantly type /zz<CR>
(which is a fast-to-type uncommon occurrence) to clear my highlighting. But the :noh
mapping is way better.
Thanks Philip this helped me - my use case was I had a form with lot of input fields so I maintained initial state as object and I was not able to update the object state.The above post helped me :)
const [projectGroupDetails, setProjectGroupDetails] = useState({
"projectGroupId": "",
"projectGroup": "DDD",
"project-id": "",
"appd-ui": "",
"appd-node": ""
});
const inputGroupChangeHandler = (event) => {
setProjectGroupDetails((prevState) => ({
...prevState,
[event.target.id]: event.target.value
}));
}
<Input
id="projectGroupId"
labelText="Project Group Id"
value={projectGroupDetails.projectGroupId}
onChange={inputGroupChangeHandler}
/>
Background images, ideally, are always done with CSS. All other images are done with html. This will span the whole background of your site.
body {
background: url('../images/cat.ong');
background-size: cover;
background-position: center;
background-attachment: fixed;
}
Your friend's PC is missing the runtime support DLLs for your program:
I think what he is trying to say is to use the
getContentPane().setBackground(Color.the_Color_you_want_here)
but if u want to set the color to any other then the JFrame, you use the object.setBackground(Color.the_Color_you_want_here)
Eg:
jPanel.setbackground(Color.BLUE)
np.random.uniform
fits your use case:
sampl = np.random.uniform(low=0.5, high=13.3, size=(50,))
Update Oct 2019:
While the syntax is still supported, it looks like the API changed with NumPy 1.17 to support greater control over the random number generator. Going forward the API has changed and you should look at https://docs.scipy.org/doc/numpy/reference/random/generated/numpy.random.Generator.uniform.html
The enhancement proposal is here: https://numpy.org/neps/nep-0019-rng-policy.html
List all your emulators:

df['Col1']=df['Col1'].apply(lambda x: '{0:0>5}'.format(x))
The 5 is the number of total digits.

Note: This answer shows how to achieve this using only the datetime
and calendar
standard library (stdlib) modules - which is what was explicitly asked for. The accepted answer shows how to better achieve this with one of the many dedicated non-stdlib libraries. If you can use non-stdlib libraries, by all means do so for these kinds of date/time manipulations!
How about this?
def add_one_month(orig_date):
# advance year and month by one month
new_year = orig_date.year
new_month = orig_date.month + 1
# note: in datetime.date, months go from 1 to 12
if new_month > 12:
new_year += 1
new_month -= 12
new_day = orig_date.day
# while day is out of range for month, reduce by one
while True:
try:
new_date = datetime.date(new_year, new_month, new_day)
except ValueError as e:
new_day -= 1
else:
break
return new_date
EDIT:
Improved version which:
calendar.monthrange
from the calendar
module in the stdlib:import datetime
import calendar
def add_one_month(orig_date):
# advance year and month by one month
new_year = orig_date.year
new_month = orig_date.month + 1
# note: in datetime.date, months go from 1 to 12
if new_month > 12:
new_year += 1
new_month -= 12
last_day_of_month = calendar.monthrange(new_year, new_month)[1]
new_day = min(orig_date.day, last_day_of_month)
return orig_date.replace(year=new_year, month=new_month, day=new_day)
d= {'george':16,'amber':19}
dict((v,k) for k,v in d.items()).get(16)
The output is as follows:
-> prints george
This issue may be occurred due to improper jquery version. like 1.4 etc. where done method is not supported
You can specify the destination directory as second parameter of the git clone
command, so you can do:
git clone <remote> .
This will clone the repository directly in the current local directory.
As you comment in your question, awk
is really the way to go. To use cut
is possible together with tr -s
to squeeze spaces, as kev's answer shows.
Let me however go through all the possible combinations for future readers. Explanations are at the Test section.
tr -s ' ' < file | cut -d' ' -f4
awk '{print $4}' file
while read -r _ _ _ myfield _
do
echo "forth field: $myfield"
done < file
sed -r 's/^([^ ]*[ ]*){3}([^ ]*).*/\2/' file
Given this file, let's test the commands:
$ cat a
this is line 1 more text
this is line 2 more text
this is line 3 more text
this is line 4 more text
$ cut -d' ' -f4 a
is
# it does not show what we want!
$ tr -s ' ' < a | cut -d' ' -f4
1
2 # this makes it!
3
4
$
$ awk '{print $4}' a
1
2
3
4
This reads the fields sequentially. By using _
we indicate that this is a throwaway variable as a "junk variable" to ignore these fields. This way, we store $myfield
as the 4th field in the file, no matter the spaces in between them.
$ while read -r _ _ _ a _; do echo "4th field: $a"; done < a
4th field: 1
4th field: 2
4th field: 3
4th field: 4
This catches three groups of spaces and no spaces with ([^ ]*[ ]*){3}
. Then, it catches whatever coming until a space as the 4th field, that it is finally printed with \1
.
$ sed -r 's/^([^ ]*[ ]*){3}([^ ]*).*/\2/' a

If the method accepts non-primitive data type then the following method can be used to invoke a private method of any class:
public static Object genericInvokeMethod(Object obj, String methodName,
Object... params) {
int paramCount = params.length;
Method method;
Object requiredObj = null;
Class<?>[] classArray = new Class<?>[paramCount];
for (int i = 0; i < paramCount; i++) {
classArray[i] = params[i].getClass();
}
try {
method = obj.getClass().getDeclaredMethod(methodName, classArray);
method.setAccessible(true);
requiredObj = method.invoke(obj, params);
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
return requiredObj;
}
The Parameter accepted are obj, methodName and the parameters. For example
public class Test {
private String concatString(String a, String b) {
return (a+b);
}
}
Method concatString can be invoked as
Test t = new Test();
String str = (String) genericInvokeMethod(t, "concatString", "Hello", "Mr.x");
If you want to submit a form using Javascript FormData API with uploading files you need to set below two options:
processData: false,
contentType: false
You can try as follows:
//Ajax Form Submission
$(document).on("click", ".afs", function (e) {
e.preventDefault();
e.stopPropagation();
var thisBtn = $(this);
var thisForm = thisBtn.closest("form");
var formData = new FormData(thisForm[0]);
//var formData = thisForm.serializeArray();
$.ajax({
type: "POST",
url: "<?=base_url();?>assignment/createAssignment",
data: formData,
processData: false,
contentType: false,
success:function(data){
if(data=='yes')
{
alert('Success! Record inserted successfully');
}
else if(data=='no')
{
alert('Error! Record not inserted successfully')
}
else
{
alert('Error! Try again');
}
}
});
});
Try this:
Using LinearLayout if you are using textview height and width match_parent You can set the gravity text to center and text alignment to center text horizontal if you are using textview height and width wrap_content then add gravity center attribute in your LinearLayout.
XML Code
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textAlignment="center"
android:gravity="center"
android:textColor="#000"
android:textSize="30sp"
android:text="Welcome to Android" />
</LinearLayout>
Java code
You can programatically do like this:-
(textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.CENTER_HORIZONTAL);
Thank you
I got this problem while using Bootstrap and I had multiple columns in each rows.
I was trying to give page-break-inside: avoid;
or break-inside: avoid;
to the col-md-6
div elements. That was not working.
I took a hint from the answers given above by DOK that floating elements do not work well with page-break-inside: avoid;
.
Instead, I had to give page-break-inside: avoid;
or break-inside: avoid;
to the <div class="row">
element. And I had multiple rows in my print page.
That is, each row only had 2 columns in it. And they always fit horizontally and do not wrap on a new line.
In another example case, if you want 4 columns in each row, then use col-md-3
.
If you want the second highest number you can use
=LARGE(E4:E9;2)
although that doesn't account for duplicates so you could get the same result as the Max
If you want the largest number that is smaller than the maximum number you can use this version
=LARGE(E4:E9;COUNTIF(E4:E9;MAX(E4:E9))+1)
If you stuck in python command line and none of above solutions worked for you,
try exit(2)
As the rank doesn't depend at all from the contacts
RANKED_RSLTS
QRY_ID | RES_ID | SCORE | RANK
-------------------------------------
A | 1 | 15 | 3
A | 2 | 32 | 1
A | 3 | 29 | 2
C | 7 | 61 | 1
C | 9 | 30 | 2
Thus :
SELECT
C.*
,R.SCORE
,MYRANK
FROM CONTACTS C LEFT JOIN
(SELECT *,
MYRANK = RANK() OVER (PARTITION BY QRY_ID ORDER BY SCORE DESC)
FROM RSLTS) R
ON C.RES_ID = R.RES_ID
AND C.QRY_ID = R.QRY_ID
You are not leveraging async / await effectively because the request thread will be blocked while executing the synchronous method ReturnAllCountries()
The thread that is assigned to handle a request will be idly waiting while ReturnAllCountries()
does it's work.
If you can implement ReturnAllCountries()
to be asynchronous, then you would see scalability benefits. This is because the thread could be released back to the .NET thread pool to handle another request, while ReturnAllCountries()
is executing. This would allow your service to have higher throughput, by utilizing threads more efficiently.
Most updated way to achieve this is:
Add this to your EditText in XML:
android:imeOptions="actionSearch"
Then in your Activity/Fragment:
EditText.setOnEditorActionListener { _, actionId, _ ->
if (actionId == EditorInfo.IME_ACTION_SEARCH) {
// Do what you want here
return@setOnEditorActionListener true
}
return@setOnEditorActionListener false
}
Just want to share with what I used so far to save your time.
Here are examples of hard-coded headers and dynamic headers (in case if don't care about data structure). In both cases I wrote some simple directive: customSort
customSort
.directive("customSort", function() {
return {
restrict: 'A',
transclude: true,
scope: {
order: '=',
sort: '='
},
template :
' <a ng-click="sort_by(order)" style="color: #555555;">'+
' <span ng-transclude></span>'+
' <i ng-class="selectedCls(order)"></i>'+
'</a>',
link: function(scope) {
// change sorting order
scope.sort_by = function(newSortingOrder) {
var sort = scope.sort;
if (sort.sortingOrder == newSortingOrder){
sort.reverse = !sort.reverse;
}
sort.sortingOrder = newSortingOrder;
};
scope.selectedCls = function(column) {
if(column == scope.sort.sortingOrder){
return ('icon-chevron-' + ((scope.sort.reverse) ? 'down' : 'up'));
}
else{
return'icon-sort'
}
};
}// end link
}
});
I used single ng-repeat
This is a good example in Fiddle (Notice, there is no jQuery library!)
<tbody>
<tr ng-repeat="item in pagedItems[currentPage] | orderBy:sortingOrder:reverse">
<td>{{item.id}}</td>
<td>{{item.name}}</td>
<td>{{item.description}}</td>
<td>{{item.field3}}</td>
<td>{{item.field4}}</td>
<td>{{item.field5}}</td>
</tr>
</tbody>

<tr>
<th ng-repeat="header in table_headers"
class="{{header.name}}" custom-sort order="header.name" sort="sort"

</th>
</tr>

<td colspan="6">

ng-class="{active: n == currentPage}"
ng-click="setPage()">

<td ng-repeat="val in item" ng-bind-html-unsafe="item[table_headers[$index].name]"></td>

As a side note:
The ng-bind-html-unsafe
is deprecated, so I used it only for Demo (2nd example). You welcome to edit.
First of all you need to remove the data-toggle attribute. We will use some JQuery, so make sure you include it.
<ul class='nav nav-tabs'>
<li class='active'><a href='#home'>Home</a></li>
<li><a href='#menu1'>Menu 1</a></li>
<li><a href='#menu2'>Menu 2</a></li>
<li><a href='#menu3'>Menu 3</a></li>
</ul>
<div class='tab-content'>
<div id='home' class='tab-pane fade in active'>
<h3>HOME</h3>
<div id='menu1' class='tab-pane fade'>
<h3>Menu 1</h3>
</div>
<div id='menu2' class='tab-pane fade'>
<h3>Menu 2</h3>
</div>
<div id='menu3' class='tab-pane fade'>
<h3>Menu 3</h3>
</div>
</div>
</div>
<script>
$(document).ready(function(){
// Handling data-toggle manually
$('.nav-tabs a').click(function(){
$(this).tab('show');
});
// The on tab shown event
$('.nav-tabs a').on('shown.bs.tab', function (e) {
alert('Hello from the other siiiiiide!');
var current_tab = e.target;
var previous_tab = e.relatedTarget;
});
});
</script>
For V4 Select2 if you want to change both the value of the select2 and the text representation of the drop down.
var intValueOfFruit = 1;
var selectOption = new Option("Fruit", intValueOfFruit, true, true);
$('#select').append(selectOption).trigger('change');
This will set not only the value behind the scenes but also the text display for the select2.

You can use the multiprocessing module added in Python 2.6. You can use pools of processes and then get results asynchronously with:
apply_async(func[, args[, kwds[, callback]]])
E.g.:
from multiprocessing import Pool
def f(x):
return x*x
if __name__ == '__main__':
pool = Pool(processes=1) # Start a worker processes.
result = pool.apply_async(f, [10], callback) # Evaluate "f(10)" asynchronously calling callback when finished.
This is only one alternative. This module provides lots of facilities to achieve what you want. Also it will be really easy to make a decorator from this.
I can't believe javascript isn't more consistent with parsing dates. And I hear the default when there is no timezone is gonna change from UTC to local -- hope the web is prepared ;)
I prefer to let Javascript do the heavy lifting when it comes to parsing dates. However it would be nice to handle the local timezone issue fairly transparently. With both of these things in mind, here is a function to do it with the current status quo -- and when Javascript changes it will still work but then can be removed (with a little time for people to catch up with older browsers/nodejs of course).
function strToDate(dateStr)
{
var dateTry = new Date(dateStr);
if (!dateTry.getTime())
{
throw new Exception("Bad Date! dateStr: " + dateStr);
}
var tz = dateStr.trim().match(/(Z)|([+-](\d{2})\:?(\d{2}))$/);
if (!tz)
{
var newTzOffset = dateTry.getTimezoneOffset() / 60;
var newSignStr = (newTzOffset >= 0) ? '-' : '+';
var newTz = newSignStr + ('0' + Math.abs(newTzOffset)).slice(-2) + ':00';
dateStr = dateStr.trim() + newTz;
dateTry = new Date(dateStr);
if (!dateTry.getTime())
{
throw new Exception("Bad Date! dateStr: " + dateStr);
}
}
return dateTry;
}
We need a date object regardless; so createone. If there is a timezone, we are done. Otherwise, create a local timezone string using the +hh:mm format (more accepted than +hhmm).
The right way to close all excel process
var _excel = new Application();
foreach (Workbook _workbook in _excel.Workbooks) {
_workbook.Close(0);
}
_excel.Quit();
_excel = null;
Using process example, this may close all the excel process regardless.
var process = System.Diagnostics.Process.GetProcessesByName("Excel");
foreach (var p in process) {
if (!string.IsNullOrEmpty(p.ProcessName)) {
try {
p.Kill();
} catch { }
}
}
I think its best used in place of a switch case statement. Imagine if we have a switch case statement as below:
option = 1
switch(option) {
case 1: print '1st option'
case 2: print '2nd option'
case 3: print '3rd option'
default: return 'No such option'
}
There is no switch
case statements available in python. We can achieve the same by using defaultdict
.
from collections import defaultdict
def default_value(): return "Default Value"
dd = defaultdict(default_value)
dd[1] = '1st option'
dd[2] = '2nd option'
dd[3] = '3rd option'
print(dd[4])
print(dd[5])
print(dd[3])
It prints:
Default Value
Default Value
3rd option
In the above snippet dd
has no keys 4 or 5 and hence it prints out a default value which we have configured in a helper function. This is quite nicer than a raw dictionary where a KeyError
is thrown if key is not present. From this it is evident that defaultdict
more like a switch case statement where we can avoid a complicated if-elif-elif-else
blocks.
One more good example that impressed me a lot from this site is:
>>> from collections import defaultdict
>>> food_list = 'spam spam spam spam spam spam eggs spam'.split()
>>> food_count = defaultdict(int) # default value of int is 0
>>> for food in food_list:
... food_count[food] += 1 # increment element's value by 1
...
defaultdict(<type 'int'>, {'eggs': 1, 'spam': 7})
>>>
If we try to access any items other than eggs
and spam
we will get a count of 0.
You may have this issue as well if you have environment variable GCC_ROOT pointing to a wrong location. Probably simplest fix could be (on *nix like system):
unset GCC_ROOT
in more complicated cases you may need to repoint it to proper location
Here is a tidyverse
option that might work depending on the data, and some caveats on its usage:
library(tidyverse)
starting_df %>%
rownames_to_column() %>%
gather(variable, value, -rowname) %>%
spread(rowname, value)
rownames_to_column()
is necessary if the original dataframe has meaningful row names, otherwise the new column names in the new transposed dataframe will be integers corresponding to the orignal row number. If there are no meaningful row names you can skip rownames_to_column()
and replace rowname
with the name of the first column in the dataframe, assuming those values are unique and meaningful. Using the tidyr::smiths
sample data would be:
smiths %>%
gather(variable, value, -subject) %>%
spread(subject, value)
Using the example starting_df
with the tidyverse
approach will throw a warning message about dropping attributes. This is related to converting columns with different attribute types into a single character column. The smiths
data will not give that warning because all columns except for subject
are doubles.
The earlier answer using as.data.frame(t())
will convert everything to a factor
if there are mixed column types unless stringsAsFactors = FALSE
is added,
whereas the tidyverse
option converts everything to a character by default if
there are mixed column types.

In my case, I am restricted to only using the sftp command.
So, I had to use a batchfile with sftp. I created a script such as the following. This assumes you are working in the /tmp directory, and you want to put the files in the destdir_on_remote_system on the remote system. This also only works with a noninteractive login. You need to set up public/private keys so you can login without entering a password. Change as needed.
#!/bin/bash
cd /tmp
# start script with list of files to transfer
ls -1 fileset1* > batchfile1
ls -1 fileset2* >> batchfile1
sed -i -e 's/^/put /' batchfile1
echo "cd destdir_on_remote_system" > batchfile
cat batchfile1 >> batchfile
rm batchfile1
sftp -b batchfile user@host
Does document.getElementById("blue") exist? if it doesn't then blue_box will be equal to null. you can't set a onclick on something that's null
You can't pass a parameter in a @selector().
It looks like you're trying to implement a callback. The best way to do that would be something like this:
[object setCallbackObject:self withSelector:@selector(myMethod:)];
Then in your object's setCallbackObject:withSelector: method: you can call your callback method.
-(void)setCallbackObject:(id)anObject withSelector:(SEL)selector {
[anObject performSelector:selector];
}
Yes, JavaScript variables will exist in the scope they are created.
var bannerID = 55;
<input id="EditBanner" type="button"
value="Edit Image" onclick="EditBanner(bannerID);"/>
function EditBanner(id) {
//Do something with id
}
If you use event handlers and jQuery it is simple also
$("#EditBanner").click(function() {
EditBanner(bannerID);
});
You wouldn’t: it’s messy and hard to read.
You’re looking for the switch
statement in the first case. The second is fine as it is but still could be converted for consistency
Ternary statements are much more suited to boolean values and alternating logic.
The ServletContext#getRealPath()
is intented to convert a web content path (the path in the expanded WAR folder structure on the server's disk file system) to an absolute disk file system path.
The "/"
represents the web content root. I.e. it represents the web
folder as in the below project structure:
YourWebProject
|-- src
| :
|
|-- web
| |-- META-INF
| | `-- MANIFEST.MF
| |-- WEB-INF
| | `-- web.xml
| |-- index.jsp
| `-- login.jsp
:
So, passing the "/"
to getRealPath()
would return you the absolute disk file system path of the /web
folder of the expanded WAR file of the project. Something like /path/to/server/work/folder/some.war/
which you should be able to further use in File
or FileInputStream
.
Note that most starters don't seem to see/realize that you can actually pass the whole web content path to it and that they often use
String absolutePathToIndexJSP = servletContext.getRealPath("/") + "index.jsp"; // Wrong!
or even
String absolutePathToIndexJSP = servletContext.getRealPath("") + "index.jsp"; // Wronger!
instead of
String absolutePathToIndexJSP = servletContext.getRealPath("/index.jsp"); // Right!
Also note that even though you can write new files into it using FileOutputStream
, all changes (e.g. new files or edited files) will get lost whenever the WAR is redeployed; with the simple reason that all those changes are not contained in the original WAR file. So all starters who are attempting to save uploaded files in there are doing it wrong.
Moreover, getRealPath()
will always return null
or a completely unexpected path when the server isn't configured to expand the WAR file into the disk file system, but instead into e.g. memory as a virtual file system.
getRealPath()
is unportable; you'd better never use itUse getRealPath()
carefully. There are actually no sensible real world use cases for it. Based on my 20 years of Java EE experience, there has always been another way which is much better and more portable than getRealPath()
.
If all you actually need is to get an InputStream
of the web resource, better use ServletContext#getResourceAsStream()
instead, this will work regardless of the way how the WAR is expanded. So, if you for example want an InputStream
of index.jsp
, then do not do:
InputStream input = new FileInputStream(servletContext.getRealPath("/index.jsp")); // Wrong!
But instead do:
InputStream input = servletContext.getResourceAsStream("/index.jsp"); // Right!
Or if you intend to obtain a list of all available web resource paths, use ServletContext#getResourcePaths()
instead.
Set<String> resourcePaths = servletContext.getResourcePaths("/");
You can obtain an individual resource as URL
via ServletContext#getResource()
. This will return null
when the resource does not exist.
URL resource = servletContext.getResource(path);
Or if you intend to save an uploaded file, or create a temporary file, then see the below "See also" links.
jnettop is another candidate.
edit: it only shows the streams, not the owner processes.
Maybe you can get the files (gems) from the gems directory?
gemsdir = "gems directory"
gems = Dir.new(gemsdir).entries
Middleware is a general term for software that serves to "glue together" separate, often complex and already existing, programs. Some software components that are frequently connected with middleware include enterprise applications and Web services.

if you are using the less source, there should be a variable for the navbar height in the variables.less
file. If you are not using the source, then you can customize it using the customize utilty that bootstrap's site provides. And then you can downloaded it and include it in your project. The variable you are looking for is: @navbar-height
You can set :
overflow-y: scroll;height: XX px
Ctrl + Alt + L works with Android Studio under xfce4 on Linux. I see that Gnome used to use this shortcut for lock screen, but in Gnome 3 it was changed to Super+L (AKA Windows+L): https://wiki.gnome.org/Design/OS/KeyboardShortcuts
/dev/tty
is a synonym for the controlling terminal (if any) of the current process. As jtl999 says, it's a character special file; that's what the c
in the ls -l
output means.
man 4 tty
or man -s 4 tty
should give you more information, or you can read the man page online here.
Incidentally, pwd > /dev/tty
doesn't necessarily print to the shell's stdout (though it is the pwd
command's standard output). If the shell's standard output has been redirected to something other than the terminal, /dev/tty
still refers to the terminal.
You can also read from /dev/tty
, which will normally read from the keyboard.
The other answers are what you asked about, but in case it’s useful to anyone else, here’s how to set the font conditionally from the screen DPI (Windows only):
set guifont=default
if has('windows')
"get dpi, strip out utf-16 garbage and new lines
"system() converts 0x00 to 0x01 for 'platform independence'
"should return something like 'PixelsPerXLogicalInch=192'
"get the part from the = to the end of the line (eg '=192') and strip
"the first character
"and convert to a number
let dpi = str2nr(strpart(matchstr(substitute(
\system('wmic desktopmonitor get PixelsPerXLogicalInch /value'),
\'\%x01\|\%x0a\|\%x0a\|\%xff\|\%xfe', '', 'g'),
\'=.*$'), 1))
if dpi > 100
set guifont=high_dpi_font
endif
endif
Suppose:
$array = array( 4 => 'apple', 7 => 'orange', 13 => 'plum' );
Just use:
$array[key($array)]
to get first element or
key($array)
to get first key.
Or you can unlink the first if you want to remove it.
In the Latest version of Laravel i.e above Laravel 5.0. It is quite simple to perform this task. In Model, inside the class just write 'use SoftDeletes'. Example
<?php
namespace App;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\SoftDeletes;
class User extends Model
{
use SoftDeletes;
}
And In Controller, you can do deletion. Example
User::where('email', '[email protected]')->delete();
or
User::where('email', '[email protected]')->softDeletes();
Make sure that you must have 'deleted_at' column in the users Table.
And if you want to pass a value from your model and want to select a radio button from the group on load based on value, than use:
Jquery:
var priority = Model.Priority; //coming for razor model in this case
var allInputIds = "#slider-vertical-" + itemIndex + " fieldset input";
$(allInputIds).val([priority]); //Select at start up
And the html:
<div id="@("slider-vertical-"+Model.Id)">
<fieldset data-role="controlgroup" data-type="horizontal" data-mini="true">
<input type="radio" name="@("radio-choice-b-"+Model.Id)" id="@("high-"+Model.Id)" value="1" checked="checked">
<label for="@("high-"+Model.Id)" style="width:100px">@UIStrings.PriorityHighText</label>
<input type="radio" name="@("radio-choice-b-"+Model.Id)" id="@("medium-"+Model.Id)" value="2">
<label for="@("medium-"+Model.Id)" style="width:100px">@UIStrings.PriorityMediumText</label>
<input type="radio" name="@("radio-choice-b-"+Model.Id)" id="@("low-"+Model.Id)" value="3">
<label for="@("low-"+Model.Id)" style="width:100px">@UIStrings.PriorityLowText</label>
</fieldset>
</div>
When I did this for a navigation database built from ARINC424 I did a fair amount of testing and looking back at the code, I used a DECIMAL(18,12) (Actually a NUMERIC(18,12) because it was firebird).
Floats and doubles aren't as precise and may result in rounding errors which may be a very bad thing. I can't remember if I found any real data that had problems - but I'm fairly certain that the inability to store accurately in a float or a double could cause problems
The point is that when using degrees or radians we know the range of the values - and the fractional part needs the most digits.
The MySQL Spatial Extensions are a good alternative because they follow The OpenGIS Geometry Model. I didn't use them because I needed to keep my database portable.
If you don't want to modify the databound object from some reason (for example you want to show some view in your grid, but you don't want it as a part of the datasource object), you might want to do this:
1.Add column manually:
DataGridViewColumn c = new DataGridViewColumn();
DataGridViewCell cell = new DataGridViewTextBoxCell();
c.CellTemplate = cell;
c.HeaderText = "added";
c.Name = "added";
c.Visible = true;
dgv.Columns.Insert(0, c);
2.In the DataBindingComplete event do something like this:
foreach (DataGridViewRow row in dgv.Rows)
{if (row.Cells[7].Value.ToString()=="1")
row.Cells[0].Value = "number one"; }
(just a stupid example)
but remember IT HAS to be in the DataBindingComplete, otherwise value will remain blank
I've seen both methods been used in seed files.
// Uncomment the below to wipe the table clean before populating
DB::table('table_name')->truncate();
//or
DB::table('table_name')->delete();
Even though you can not use the first one if you want to set foreign keys.
Cannot truncate a table referenced in a foreign key constraint
So it might be a good idea to use the second one.
the command should be java -version
$ echo -n 'Hello world!' | hd
00000000 48 65 6c 6c 6f 20 77 6f 72 6c 64 21 |Hello world!|
0000000c
Normal text editors are nano
, or vi
.
For example:
root@user:# nano galfit.feedme
or
root@user:# vi galfit.feedme
You can use the following command to
kill -9 $(ps aux | grep 'process' | grep -v 'grep' | awk '{print $2}')
Use the @ViewChildren decorator combined with QueryList. Both of these are from "@angular/core"
@ViewChildren(CustomComponent) customComponentChildren: QueryList<CustomComponent>;
Doing something with each child looks like:
this.customComponentChildren.forEach((child) => { child.stuff = 'y' })
There is further documentation to be had at angular.io, specifically: https://angular.io/docs/ts/latest/cookbook/component-communication.html#!#sts=Parent%20calls%20a%20ViewChild
By using https://github.com/nick318/FindElementInFrames You can find webElement across all frames:
SearchByFramesFactory searchFactory = new SearchByFramesFactory(driver);
SearchByFrames searchInFrame = searchFactory.search(() -> driver.findElement(By.tagName("body")));
Optional<WebElement> elem = searchInFrame.getElem();
The above answer is correct. Works really well. There is also quick way to do this.
Type - echo export "ANDROID_HOME=/Users/yourName/Library/Android/sdk" >> ~/.bash_profile
Thats's it.
Close your terminal.
Open it again.
Type - echo $ANDROID_HOME to check if the home is set.

For those who want to get height and width of device even when the display is resized (dynamically & in real-time):
In that Component do: import { HostListener } from "@angular/core";
In the component's class body write:
@HostListener('window:resize', ['$event'])
onResize(event?) {
this.screenHeight = window.innerHeight;
this.screenWidth = window.innerWidth;
}
In the component's constructor
call the onResize
method to initialize the variables. Also, don't forget to declare them first.
constructor() {
this.onResize();
}
Complete code:
import { Component, OnInit } from "@angular/core";
import { HostListener } from "@angular/core";
@Component({
selector: "app-login",
templateUrl: './login.component.html',
styleUrls: ['./login.component.css']
})
export class FooComponent implements OnInit {
screenHeight: number;
screenWidth: number;
constructor() {
this.getScreenSize();
}
@HostListener('window:resize', ['$event'])
getScreenSize(event?) {
this.screenHeight = window.innerHeight;
this.screenWidth = window.innerWidth;
console.log(this.screenHeight, this.screenWidth);
}
}
I know this isn't going to help, but it might help someone in the future.
I've just had the same problem, closing and re-opening the services manager removed both the entry from the registry and completed the uninstall of the service.
Previous to that, refreshing the services manager hadn't helped.
Very Simple with no extra code, just input, conversion and output.
using System;
namespace _01.Decimal_to_Binary
{
class DecimalToBinary
{
static void Main(string[] args)
{
Console.Write("Decimal: ");
int decimalNumber = int.Parse(Console.ReadLine());
int remainder;
string result = string.Empty;
while (decimalNumber > 0)
{
remainder = decimalNumber % 2;
decimalNumber /= 2;
result = remainder.ToString() + result;
}
Console.WriteLine("Binary: {0}",result);
}
}
}
You can use one-line heredoc
cat <<< "This is coming from the stdin"
the above is the same as
cat <<EOF
This is coming from the stdin
EOF
or you can redirect output from a command, like
diff <(ls /bin) <(ls /usr/bin)
or you can read as
while read line
do
echo =$line=
done < some_file
or simply
echo something | read param
Depending on the schema/account you are using to connect to the database, I would suspect you are missing a grant to the account you are using to connect to the database.
Connect as PCT account in the database, then grant the account you are using select access for the table.
grant select on pi_int to Account_used_to_connect
In order to populate referenced subdocuments, you need to explicitly define the document collection to which the ID references to (like created_by: { type: Schema.Types.ObjectId, ref: 'User' }
).
Given this reference is defined and your schema is otherwise well defined as well, you can now just call populate
as usual (e.g. populate('comments.created_by')
)
Proof of concept code:
// Schema
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var UserSchema = new Schema({
name: String
});
var CommentSchema = new Schema({
text: String,
created_by: { type: Schema.Types.ObjectId, ref: 'User' }
});
var ItemSchema = new Schema({
comments: [CommentSchema]
});
// Connect to DB and instantiate models
var db = mongoose.connect('enter your database here');
var User = db.model('User', UserSchema);
var Comment = db.model('Comment', CommentSchema);
var Item = db.model('Item', ItemSchema);
// Find and populate
Item.find({}).populate('comments.created_by').exec(function(err, items) {
console.log(items[0].comments[0].created_by.name);
});
Finally note that populate
works only for queries so you need to first pass your item into a query and then call it:
item.save(function(err, item) {
Item.findOne(item).populate('comments.created_by').exec(function (err, item) {
res.json({
status: 'success',
message: "You have commented on this item",
comment: item.comments.id(comment._id)
});
});
});
Insert this in your Makefile
$(MAKE) -C $(KDIR) M=$(PWD) modules_install
it will install the module in the directory /lib/modules/<var>/extra/
After make , insert module with modprobe module_name (without .ko extension)
OR
After your normal make, you copy module module_name.ko into directory /lib/modules/<var>/extra/
then do modprobe module_name (without .ko extension)
Swift 4.0
you create the Selector like below.
1.add the event to a button like:
button.addTarget(self, action: #selector(clickedButton(sender:)), for: UIControlEvents.touchUpInside)
and the function will be like below:
@objc func clickedButton(sender: AnyObject) {
}
You do not include a <scope>
tag in your dependency. If you add it, your dependency becomes something like:
<dependency>
<groupId>org.openrdf.sesame</groupId>
<artifactId>sesame-runtime</artifactId>
<version>2.7.2</version>
<scope> ... </scope>
</dependency>
The "scope" tag tells maven at which stage of the build your dependency is needed. Examples for the values to put inside are "test", "provided" or "runtime" (omit the quotes in your pom). I do not know your dependency so I cannot tell you what value to choose. Please consult the Maven documentation and the documentation of your dependency.
A refinement on the answer by JSmyth:
console.logCopy = console.log.bind(console);
console.log = function()
{
if (arguments.length)
{
var timestamp = new Date().toJSON(); // The easiest way I found to get milliseconds in the timestamp
var args = arguments;
args[0] = timestamp + ' > ' + arguments[0];
this.logCopy.apply(this, args);
}
};
This:
.log
Another approach is to use ngModelChange
:
Template:
<input type="checkbox" ngModel (ngModelChange)="onChecked(obj, $event)" />
Controller:
onChecked(obj: any, isChecked: boolean){
console.log(obj, isChecked); // {}, true || false
}
I prefer this method because here you get the relevant object and true
/false
values of a checkbox.
Here's a solution that uses httplib
instead.
import httplib
def get_status_code(host, path="/"):
""" This function retreives the status code of a website by requesting
HEAD data from the host. This means that it only requests the headers.
If the host cannot be reached or something else goes wrong, it returns
None instead.
"""
try:
conn = httplib.HTTPConnection(host)
conn.request("HEAD", path)
return conn.getresponse().status
except StandardError:
return None
print get_status_code("stackoverflow.com") # prints 200
print get_status_code("stackoverflow.com", "/nonexistant") # prints 404
We had the same issue while trying to launch Selenium tests from Jenkins. I had selected the 'Start Xvfb before the build, and shut it down after' box and passed in the necessary screen options, but I was still getting this error.
It finally worked when we passed in the following commands in the Execute Shell box.
Xvfb :99 -ac -screen 0 1280x1024x24 &
nice -n 10 x11vnc 2>&1 &
...
killall Xvfb
I figured it out!
After reading this blog post I realized that the placement of this line:
<script src="{% static "build/react.js" %}"></script>
was wrong. That line needs to be the last line in the <body>
section, right before the </body>
tag. Moving the line down solves the problem.
My explanation for this is that react was looking for the id in between the <head>
tags, instead of in the <body>
tags. Because of this it couldn't find the content
id, and thus it wasn't a real DOM element.
This can help too
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int i, float v, int i1) {
}
@Override
public void onPageSelected(int i) {
tablayout.getTabAt(i).select();
}
@Override
public void onPageScrollStateChanged(int i) {
}
});
This basically has to do with the hardware architecture (i.e. RAM and caches).
If you don't use synchronized
together with wait()
or notify()
, another thread could enter the same block instead of waiting for the monitor to enter it. Moreover, when e.g. accessing an array without a synchronized block, another thread may not see the changement to it...actually another thread will not see any changements to it when it already has a copy of the array in the x-level cache (a.k.a. 1st/2nd/3rd-level caches) of the thread handling CPU core.
But synchronized blocks are only one side of the medal: If you actually access an object within a synchronized context from a non-synchronized context, the object still won't be synchronized even within a synchronized block, because it holds an own copy of the object in its cache. I wrote about this issues here: https://stackoverflow.com/a/21462631 and When a lock holds a non-final object, can the object's reference still be changed by another thread?
Furthermore, I'm convinced that the x-level caches are responsible for most non-reproducible runtime errors. That's because the developers usually don't learn the low-level stuff, like how CPU's work or how the memory hierarchy affects the running of applications: http://en.wikipedia.org/wiki/Memory_hierarchy
It remains a riddle why programming classes don't start with memory hierarchy and CPU architecture first. "Hello world" won't help here. ;)
First few lines: man head
.
Append lines: use the >>
operator (?) in Bash:
echo 'This goes at the end of the file' >> file
You can use the simple not flag to validate that. Example
if !@objectname
This will return true if @objectname is nil. You should not use dot operator or a nil value, else it will throw
*** NoMethodError Exception: undefined method `isNil?' for nil:NilClass
An ideal nil check would be like:
!@objectname || @objectname.nil? || @objectname.empty?
You have to cast, I'm afraid:
f((byte)0);
I believe that will perform the appropriate conversion at compile-time instead of execution time, so it's not actually going to cause performance penalties. It's just inconvenient :(
Another way to refresh the current page using selenium in Java.
//first: get the current URL in a String variable
String currentURL = driver.getCurrentUrl();
//second: call the current URL
driver.get(currentURL);
Using this will refresh the current page like clicking the address bar of the browser and pressing enter.
If this is for some configuration file processing, consider using Apache configuration. https://commons.apache.org/proper/commons-configuration/javadocs/v1.10/apidocs/index.html?org/apache/commons/configuration/PropertiesConfiguration.html It has way to multiple values to single key- The format is bit different though
key=value1,value2,valu3
gives three values against same key.

Should do it. Assuming you don't need it to flow.
Use ./gradlew
instead of gradle
to resolve this issue.
Figured this out. Pretty simple:
new PDO("sqlsrv:server=[sqlservername];Database=[sqlserverdbname]", "[username]", "[password]");
If you use the ino command line:
ino upload
it can be because you use the arduino software at the same time, try to kill it.
Remove your script, and change the HTML:
<a id="closemodal" href="https://www.google.com" class="btn btn-primary close" data-dismiss="modal" target="_blank">Launch google.com</a>
EDIT: Please note that currently this will not work as this functionality does not yet exist in bootstrap. See issue here.
In my case, the problem was I used wrong alias for git commit -m
. I used gc
alias which dit not meant git commit -m
Unless I misunderstand your question, you can just open a file read only. Here is a simply example, without any checks.
To get the file path from the user use this function:
Private Function get_user_specified_filepath() As String
'or use the other code example here.
Dim fd As Office.FileDialog
Set fd = Application.FileDialog(msoFileDialogFilePicker)
fd.AllowMultiSelect = False
fd.Title = "Please select the file."
get_user_specified_filepath = fd.SelectedItems(1)
End Function
Then just open the file read only and assign it to a variable:
dim wb as workbook
set wb = Workbooks.Open(get_user_specified_filepath(), ReadOnly:=True)
press escape and then type below combinations fast:
gg=G
You can keep primitive type by setting default value, in the your case just add "required = false" property:
@RequestParam(value = "i", required = false, defaultValue = "10") int i
P.S. This page from Spring documentation might be useful: Annotation Type RequestParam
You could wrap the hidden div in another div that will toggle the visibility with onMouseOver and onMouseOut event handlers in JavaScript:
<style type="text/css">
#div1, #div2, #div3 {
visibility: hidden;
}
</style>
<script>
function show(id) {
document.getElementById(id).style.visibility = "visible";
}
function hide(id) {
document.getElementById(id).style.visibility = "hidden";
}
</script>
<div onMouseOver="show('div1')" onMouseOut="hide('div1')">
<div id="div1">Div 1 Content</div>
</div>
<div onMouseOver="show('div2')" onMouseOut="hide('div2')">
<div id="div2">Div 2 Content</div>
</div>
<div onMouseOver="show('div3')" onMouseOut="hide('div3')">
<div id="div3">Div 3 Content</div>
</div>
I depends on the version and the distro.
For example the default download pre-2.2 from the MongoDB site uses: /data/db
but the Ubuntu install at one point used to use: var/lib/mongodb
.
I think these have been standardised now so that 2.2+ will only use data/db
whether it comes from direct download on the site or from the repos.
A2 Hosting permits node.js on their shared hosting accounts. I can vouch that I've had a positive experience with them.
Here are instructions in their KnowledgeBase for installing node.js using Apache/LiteSpeed as a reverse proxy: https://www.a2hosting.com/kb/installable-applications/manual-installations/installing-node-js-on-managed-hosting-accounts . It takes about 30 minutes to set up the configuration, and it'll work with npm, Express, MySQL, etc.
