There's always git describe
as well. By default it gives you --
john@eleanor:/dev/shm/mpd/ncmpc/pkg (master)$ git describe --always
release-0.19-11-g7a68a75
it's a good idea to use a reset CSS. add this at the top of your CSS file
img, a {border:none, outline: none;}
hope this helps
First rename your module from app to i.e. SurveyApp
Second add this to your project top-level (root project) gradle. It's working with Gradle 3.0
//rename apk for all sub projects
subprojects {
afterEvaluate { project ->
if (project.hasProperty("android")) {
android.applicationVariants.all { variant ->
variant.outputs.all {
outputFileName = "${project.name}-${variant.name}-${variant.versionName}.apk"
}
}
}
}
}
When i inspect the console i found that the version of maven compiler is 2.5.1 but in other side i try to build my project with maven 3.2.2.So after writting the exact version in pom.xml, it works good. Here is the full tag:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.2</version>
<configuration>

Try wkhtmltopdf with either one of the following wrappers
django-wkhtmltopdf or python-pdfkit
This worked great for me,supports javascript and css or anything for that matter which a webkit browser supports.

Within Excel you need to set a reference to the VB script run-time library.
The relevant file is usually located at \Windows\System32\scrrun.dll
Microsoft Scripting Runtime
'scrrun.dll
file will be displayed below the listboxThis can also be done directly in the code if access to the VBA object model has been enabled.
Access can be enabled by ticking the check-box Trust access to the VBA project object model
found at File > Options > Trust Center > Trust Center Settings > Macro Settings
To add a reference:
Sub Add_Reference()
Application.VBE.ActiveVBProject.References.AddFromFile "C:\Windows\System32\scrrun.dll"
'Add a reference
End Sub
To remove a reference:
Sub Remove_Reference()
Dim oReference As Object
Set oReference = Application.VBE.ActiveVBProject.References.Item("Scripting")
Application.VBE.ActiveVBProject.References.Remove oReference
'Remove a reference
End Sub
Update - as of Spark 1.6, you can simply use the built-in csv data source:
spark: SparkSession = // create the Spark Session
val df = spark.read.csv("file.txt")
You can also use various options to control the CSV parsing, e.g.:
val df = spark.read.option("header", "false").csv("file.txt")
For Spark version < 1.6:
The easiest way is to use spark-csv - include it in your dependencies and follow the README, it allows setting a custom delimiter (;
), can read CSV headers (if you have them), and it can infer the schema types (with the cost of an extra scan of the data).
Alternatively, if you know the schema you can create a case-class that represents it and map your RDD elements into instances of this class before transforming into a DataFrame, e.g.:
case class Record(id: Int, name: String)
val myFile1 = myFile.map(x=>x.split(";")).map {
case Array(id, name) => Record(id.toInt, name)
}
myFile1.toDF() // DataFrame will have columns "id" and "name"
Use typings to access node functions from TypeScript:
typings install env~node --global
If you don't have typings install it:
npm install typings --global
There is this extensions that adds an event listener to attribute changes.
Usage:
<script type="text/javascript" src="http://code.jquery.com/jquery.min.js"></script>
<script type="text/javascript"
src="https://cdn.rawgit.com/meetselva/attrchange/master/js/attrchange.js"></script>
Bind attrchange handler function to selected elements
$(selector).attrchange({
trackValues: true, /* Default to false, if set to true the event object is
updated with old and new value.*/
callback: function (event) {
//event - event object
//event.attributeName - Name of the attribute modified
//event.oldValue - Previous value of the modified attribute
//event.newValue - New value of the modified attribute
//Triggered when the selected elements attribute is added/updated/removed
}
});
An alternative answer is to reshape the array so that it has dimensions (1, N)
like so:
savetext(filename, a.reshape(1, a.shape[0]))
Use this typesafe pattern with poison pills:
public sealed interface BaseMessage {
final class ValidMessage<T> implements BaseMessage {
@Nonnull
private final T value;
public ValidMessage(@Nonnull T value) {
this.value = value;
}
@Nonnull
public T getValue() {
return value;
}
@Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
ValidMessage<?> that = (ValidMessage<?>) o;
return value.equals(that.value);
}
@Override
public int hashCode() {
return Objects.hash(value);
}
@Override
public String toString() {
return "ValidMessage{value=%s}".formatted(value);
}
}
final class PoisonedMessage implements BaseMessage {
public static final PoisonedMessage INSTANCE = new PoisonedMessage();
private PoisonedMessage() {
}
@Override
public String toString() {
return "PoisonedMessage{}";
}
}
}
public class Producer implements Callable<Void> {
@Nonnull
private final BlockingQueue<BaseMessage> messages;
Producer(@Nonnull BlockingQueue<BaseMessage> messages) {
this.messages = messages;
}
@Override
public Void call() throws Exception {
messages.put(new BaseMessage.ValidMessage<>(1));
messages.put(new BaseMessage.ValidMessage<>(2));
messages.put(new BaseMessage.ValidMessage<>(3));
messages.put(BaseMessage.PoisonedMessage.INSTANCE);
return null;
}
}
public class Consumer implements Callable<Void> {
@Nonnull
private final BlockingQueue<BaseMessage> messages;
private final int maxPoisons;
public Consumer(@Nonnull BlockingQueue<BaseMessage> messages, int maxPoisons) {
this.messages = messages;
this.maxPoisons = maxPoisons;
}
@Override
public Void call() throws Exception {
int poisonsReceived = 0;
while (poisonsReceived < maxPoisons && !Thread.currentThread().isInterrupted()) {
BaseMessage message = messages.take();
if (message instanceof BaseMessage.ValidMessage<?> vm) {
Integer value = (Integer) vm.getValue();
System.out.println(value);
} else if (message instanceof BaseMessage.PoisonedMessage) {
++poisonsReceived;
} else {
throw new IllegalArgumentException("Invalid BaseMessage type: " + message);
}
}
return null;
}
}
public static class DateTool
{
public static DateTime Min(DateTime x, DateTime y)
{
return (x.ToUniversalTime() < y.ToUniversalTime()) ? x : y;
}
public static DateTime Max(DateTime x, DateTime y)
{
return (x.ToUniversalTime() > y.ToUniversalTime()) ? x : y;
}
}
This allows the dates to have different 'kinds' and returns the instance that was passed in (not returning a new DateTime constructed from Ticks or Milliseconds).
[TestMethod()]
public void MinTest2()
{
DateTime x = new DateTime(2001, 1, 1, 1, 1, 2, DateTimeKind.Utc);
DateTime y = new DateTime(2001, 1, 1, 1, 1, 1, DateTimeKind.Local);
//Presumes Local TimeZone adjustment to UTC > 0
DateTime actual = DateTool.Min(x, y);
Assert.AreEqual(x, actual);
}
Note that this test would fail East of Greenwich...
You can use the StringUtils.join()
method of Apache Commons Lang:
String join = StringUtils.join(joinList, "+");
The whole point of a class is that you create an instance, and that instance encapsulates a set of data. So it's wrong to say that your variables are global within the scope of the class: say rather that an instance holds attributes, and that instance can refer to its own attributes in any of its code (via self.whatever
). Similarly, any other code given an instance can use that instance to access the instance's attributes - ie instance.whatever
.
Take a look at this post on Java Ranch:
http://www.coderanch.com/t/300287/JDBC/java/Io-Exception-Network-Adapter-could
"The solution for my "Io exception: The Network Adapter could not establish the connection" exception was to replace the IP of the database server to the DNS name."
This works for me on the webpack.config.js
new webpack.ProvidePlugin({
$: 'jquery',
jQuery: 'jquery',
'window.jQuery': 'jquery'
}),
in another javascript or into HTML add:
global.jQuery = require('jquery');
After trying the above suggestions, the only thing that worked for me was changing the border attribute to "0" in the following sections of a child theme's style.css (do a "Find" operation to locate each one -- the following are just snippets):
.comment-content table {
border-bottom: 1px solid #ddd;
.comment-content td {
border-top: 1px solid #ddd;
padding: 6px 10px 6px 0;
}
Thus looking like this afterwards:
.comment-content table {
border-bottom: 0;
.comment-content td {
border-top: 0;
padding: 6px 10px 6px 0;
}
Return output first true value.
If all are false return last false value.
Example:-
null || undefined || false || 0 || 'apple' // Return apple
In Java 8:
Arrays.sort(files, (a, b) -> a.getName().compareTo(b.getName()));
Reverse order:
Arrays.sort(files, (a, b) -> -a.getName().compareTo(b.getName()));
ManagementObjectSearcher("SELECT UserName FROM Win32_ComputerSystem") solution worked fine for me. BUT it does not work if the service is started over a Remote Desktop Connection. To work around this, we can ask for the username of the owner of an interactive process that always is running on a PC: explorer.exe. This way, we always get the currently Windows logged-in username from our Windows service:
foreach (System.Management.ManagementObject Process in Processes.Get())
{
if (Process["ExecutablePath"] != null &&
System.IO.Path.GetFileName(Process["ExecutablePath"].ToString()).ToLower() == "explorer.exe" )
{
string[] OwnerInfo = new string[2];
Process.InvokeMethod("GetOwner", (object[])OwnerInfo);
Console.WriteLine(string.Format("Windows Logged-in Interactive UserName={0}", OwnerInfo[0]));
break;
}
}
To update a single local package:
First find out your outdated packages:
npm outdated
Then update the package or packages that you want manually as:
npm update --save package_name
This way it is not necessary to update your local package.json
file.
Note that this will update your package to the latest version.
If you write some version in your package.json
file and do:
npm update package_name
In this case you will get just the next stable version (wanted) regarding the version that you wrote in your package.json
file.
And with npm list (package_name)
you can find out the current version of your local packages.
Instead of using the "c" tags, you could also do the following:
<h:outputLink value="Images/thumb_02.jpg" target="_blank" rendered="#{not empty user or user.userId eq 0}" />
<h:graphicImage value="Images/thumb_02.jpg" rendered="#{not empty user or user.userId eq 0}" />
<h:outputLink value="/DisplayBlobExample?userId=#{user.userId}" target="_blank" rendered="#{not empty user and user.userId neq 0}" />
<h:graphicImage value="/DisplayBlobExample?userId=#{user.userId}" rendered="#{not empty user and user.userId neq 0}"/>
I think that's a little more readable alternative to skuntsel's alternative answer and is utilizing the JSF rendered attribute instead of nesting a ternary operator. And off the answer, did you possibly mean to put your image in between the anchor tags so the image is clickable?
It happens when you call a file usually by include
, require
or fopen
and PHP couldn't find the file or have not enough permission to load the file.
This can happen for a variety of reasons :
One common mistake is to not use an absolute path. This can be easily solved by using a full path or magic constants like __DIR__
or dirname(__FILE__)
:
include __DIR__ . '/inc/globals.inc.php';
or:
require dirname(__FILE__) . '/inc/globals.inc.php';
Ensuring the right path is used is one step in troubleshooting these issues, this can also be related to non-existing files, rights of the filesystem preventing access or open basedir restrictions by PHP itself.
The best way to solve this problem quickly is to follow the troubleshooting checklist below.

The .css()
function doesn't queue behind running animations, it's instantaneous.
To match the behaviour that you're after, you'd need to do the following:
$(document).ready(function() {
$("button").mouseover(function() {
var p = $("p#44.test").css("background-color", "yellow");
p.hide(1500).show(1500);
p.queue(function() {
p.css("background-color", "red");
});
});
});
The .queue()
function waits for running animations to run out and then fires whatever's in the supplied function.

System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure
Fortunately, the certificate was generated using a chain. Of course, you can always ignore this solution and use the above solutions.
So here is my solution:
I saved the certificate using Chrome on my computer in P7B format.
Convert certificate to PEM format using this command:
openssl pkcs7 -inform DER -outform PEM -in <cert>.p7b -print_certs > ca_bundle.crt
Open the ca_bundle.crt file and delete all Subject recordings, leaving a clean file. Example below:
-----BEGIN CERTIFICATE-----
_BASE64 DATA_
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
_BASE64 DATA_
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
_BASE64 DATA_
-----END CERTIFICATE-----

RUN apt-get update && apt-get install -y curl && apt-get install -y ca-certificates

I know its way too old to be answered now.. but still, a small tweak to @Daniel's answer for rectifying the problem of not showing zero valued progress bar. Just draw the Progress only if the inner rectangle's width is found to be non-zero.
Thanks to all the contributers.
public class ProgressBarEx : ProgressBar
{
public ProgressBarEx()
{
this.SetStyle(ControlStyles.UserPaint, true);
}
protected override void OnPaintBackground(PaintEventArgs pevent){}
// None... Helps control the flicker.
protected override void OnPaint(PaintEventArgs e)
{
const int inset = 2; // A single inset value to control teh sizing of the inner rect.
using (Image offscreenImage = new Bitmap(this.Width, this.Height))
{
using (Graphics offscreen = Graphics.FromImage(offscreenImage))
{
Rectangle rect = new Rectangle(0, 0, this.Width, this.Height);
if (ProgressBarRenderer.IsSupported)
ProgressBarRenderer.DrawHorizontalBar(offscreen, rect);
rect.Inflate(new Size(-inset, -inset)); // Deflate inner rect.
rect.Width = (int)(rect.Width * ((double)this.Value / this.Maximum));
if (rect.Width != 0)
{
LinearGradientBrush brush = new LinearGradientBrush(rect, this.ForeColor, this.BackColor, LinearGradientMode.Vertical);
offscreen.FillRectangle(brush, inset, inset, rect.Width, rect.Height);
e.Graphics.DrawImage(offscreenImage, 0, 0);

Use the str.isspace()
method:
Return
True
if there are only whitespace characters in the string and there is at least one character,False
otherwise.A character is whitespace if in the Unicode character database (see unicodedata), either its general category is Zs (“Separator, space”), or its bidirectional class is one of WS, B, or S.
Combine that with a special case for handling the empty string.
Alternatively, you could use str.strip()
and check if the result is empty.
One of my coworker shared this regex with me. I like it a lot.
function isValidEmailAddress (email) {
var validEmail = false;
if (email) {
email = email.trim().toLowerCase();
var pattern = /^[\w-']+(\.[\w-']+)*@([a-zA-Z0-9]+[a-zA-Z0-9-]+(\.[a-zA-Z0-9-]+)*?\.[a-zA-Z]{2,6}|(\d{1,3}\.){3}\d{1,3})(:\d{4})?$/;
validEmail = pattern.exec(email);
}
return validEmail;
}
if (typeof String.prototype.trim !== 'function') {
String.prototype.trim = function() {
return this.replace(/^\s+|\s+$/g, '');
};
}
I believe you can hide it with CSS:
.ui-dialog-titlebar {
display: none;
}
Alternatively, you can apply this to specific dialogs with the dialogClass
option:
$( "#createUserDialog" ).dialog({
dialogClass: "no-titlebar"
});
.no-titlebar .ui-dialog-titlebar {
display: none;
}
Check out "Theming" the Dialog. The above suggestion makes use of the dialogClass
option, which appears to be on it's way out in favor of a new method.
Autofill works with name attribute of the input, so if you set a name for an input like "firstname", chrome will fill it.
If you want to disable it, use an odd name like "supermanname".
Javascript can't solve your problem.
Second solution: You can make your inputs hidden with the same names, and set their values with other inputs. I simplified the Js with jQUery.
<form action="handlerfile.php" method="post">
<input type="text" id="1" onclick="$("#2").val($("#1").val())"/>
<input type="hidden" name="username" id="2">
</form>
Write a program to accept two integers and output the largest of two numbers to a file at a location of your choice. Now describe what each statement does.
It's possible to drill down pretty deep starting from the significance of the import statement, right down to abnormal termination
CASE is the answer, but you will need to have a separate case statement for each column you want returned. As long as the WHERE clause is the same, there won't be much benefit separating it out into multiple queries.
Example:
SELECT
CASE @var
WHEN 'xyz' THEN col1
WHEN 'zyx' THEN col2
ELSE col7
END,
CASE @var
WHEN 'xyz' THEN col2
WHEN 'zyx' THEN col3
ELSE col8
END
FROM Table
...
I normally have them in an array and call writeBooleanArray
and readBooleanArray
If it's a single boolean you need to pack, you could do this:
parcel.writeBooleanArray(new boolean[] {myBool});
The previous answers still leave room for improvement because of the possibilities, the intuitiveness of the code, and the use of id
versus name
. One can get a read-out of three data of a selected option -- its index number, its value and its text. This simple, cross-browser code does all three:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Demo GetSelectOptionData</title>
</head>
<body>
<form name="demoForm">
<select name="demoSelect" onchange="showData()">
<option value="zilch">Select:</option>
<option value="A">Option 1</option>
<option value="B">Option 2</option>
<option value="C">Option 3</option>
</select>
</form>
<p id="firstP"> </p>
<p id="secondP"> </p>
<p id="thirdP"> </p>
<script>
function showData() {
var theSelect = demoForm.demoSelect;
var firstP = document.getElementById('firstP');
var secondP = document.getElementById('secondP');
var thirdP = document.getElementById('thirdP');
firstP.innerHTML = ('This option\'s index number is: ' + theSelect.selectedIndex + ' (Javascript index numbers start at 0)');
secondP.innerHTML = ('Its value is: ' + theSelect[theSelect.selectedIndex].value);
thirdP.innerHTML = ('Its text is: ' + theSelect[theSelect.selectedIndex].text);
}
</script>
</body>
</html>
Live demo: http://jsbin.com/jiwena/1/edit?html,output .
id
should be used for make-up purposes. For functional form purposes, name
is still valid, also in HTML5, and should still be used. Lastly, mind the use of square versus round brackets in certain places. As was explained before, only (older versions of) Internet Explorer will accept round ones in all places.
The query can be written slightly simpler, like this:
DECLARE @T INT = 2
SELECT CASE
WHEN @T < 1 THEN 'less than one'
WHEN @T = 1 THEN 'one'
ELSE 'greater than one'
END T
To print to any printer on the network you can send a PJL/PCL print job directly to a network printer on port 9100.
Please have a look at the below link that should give a good start:
http://frank.zinepal.com/printing-directly-to-a-network-printer
Also, If there is a way to call Windows cmd you can use FTP put to print your page on 9100. Below link should give you details, I have used this method for HP printers but I believe it will work for other printers.

Person result = (from p in Context.Persons
where p.person_id == 5
select p).SingleOrDefault();
result.is_default = false;
Context.SaveChanges();
and here's how you update multiple records:
List<Person> results = (from p in Context.Persons
where .... // add where condition here
select p).ToList();
foreach (Person p in results)
{
p.is_default = false;

This is an older thread, but I just searched and found it. I am new to using Web Developer Tools: primarily Firefox Developer Tools (Firefox v.51), but also Chrome DevTools (Chrome v.56)].
I wasn't able to run functions from the Developer Tools console, but I then found this
https://developer.mozilla.org/en-US/docs/Tools/Scratchpad
and I was able to add code to the Scratchpad, highlight and run a function, outputted to console per the attched screenshot.
I also added the Chrome "Scratch JS" extension: it looks like it provides the same functionality as the Scratchpad in Firefox Developer Tools (screenshot below).

Actually VBA can be used to compile DLLs. The Office 2000 and Office XP Developer editions included a VBA editor that could be used for making DLLs for use as COM Addins.
This functionality was removed in later versions (2003 and 2007) with the advent of the VSTO (VS Tools for Office) software, although obviously you could still create COM addins in a similar fashion without the use of VSTO (or VS.Net) by using VB6 IDE.

I had this issue in VS 2015. The following solved it for me:
Find "webpages:Version" in the appsettings and update it to version 3.0.0.0. My web.config had
<add key="webpages:Version" value="2.0.0.0" />
and I updated it to
<add key="webpages:Version" value="3.0.0.0" />
Most of the time we go for OrderedDict when we required a custom order not a generic one like ASC etc.
Here is the proposed solution:
import collections
ship = {"NAME": "Albatross",
"HP":50,
"BLASTERS":13,
"THRUSTERS":18,
"PRICE":250}
ship = collections.OrderedDict(ship)
print ship
new_dict = collections.OrderedDict()
new_dict["NAME"]=ship["NAME"]
new_dict["HP"]=ship["HP"]
new_dict["BLASTERS"]=ship["BLASTERS"]
new_dict["THRUSTERS"]=ship["THRUSTERS"]
new_dict["PRICE"]=ship["PRICE"]
print new_dict
This will be output:
OrderedDict([('PRICE', 250), ('HP', 50), ('NAME', 'Albatross'), ('BLASTERS', 13), ('THRUSTERS', 18)])
OrderedDict([('NAME', 'Albatross'), ('HP', 50), ('BLASTERS', 13), ('THRUSTERS', 18), ('PRICE', 250)])
Note: The new sorted dictionaries maintain their sort order when entries are deleted. But when new keys are added, the keys are appended to the end and the sort is not maintained.(official doc)
As you have already stated in your question you have more than one option. A very basic approach would be using the tag referencing your PHP file in the method attribute. However as esoteric as it may sound AJAX is a more complete approach. Considering that an AJAX call (in combination with jQuery) can be as simple as:
$.post("yourfile.php", {data : "This can be as long as you want"});
And you get a more flexible solution, for example triggering a function after the server request is completed. Hope this helps.
Use backticks for system commands, which helps to store their results into Perl variables.
my $pid = 5892;
my $not = ``top -H -p $pid -n 1 | grep myprocess | wc -l`;
print "not = $not\n";
It formats the string as two uppercase hexadecimal characters.
In more depth, the argument "X2"
is a "format string" that tells the ToString()
method how it should format the string. In this case, "X2" indicates the string should be formatted in Hexadecimal.
byte.ToString()
without any arguments returns the number in its natural decimal representation, with no padding.
Microsoft documents the standard numeric format strings which generally work with all primitive numeric types' ToString()
methods. This same pattern is used for other types as well: for example, standard date/time format strings can be used with DateTime.ToString()
.
app.get('/fruit/:fruitName/:fruitColor', function(req, res) {
var data = {
"fruit": {
"apple": req.params.fruitName,
"color": req.params.fruitColor
}
};
send.json(data);
});
If that doesn't work, try using console.log(req.params) to see what it is giving you.
You want hasOwnProperty()
:
var myObj1 = { _x000D_
prop1: 'no',_x000D_
prop2: function () { return false; }_x000D_
}_x000D_
var myObj2 = { _x000D_
prop1: 'no'_x000D_
}_x000D_
_x000D_
console.log(myObj1.hasOwnProperty('prop2')); // returns true_x000D_
console.log(myObj2.hasOwnProperty('prop2')); // returns false_x000D_
_x000D_

Here is the Best and shortest solution that works for me as of may, 2018 for Laravel 5.5
just cut your .htaccess
file from the /public directory to the root directory and replace it content with the following code:
<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
Options -MultiViews
</IfModule>
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)/$ /$1 [L,R=301]
RewriteCond %{REQUEST_URI} !(\.css|\.js|\.png|\.jpg|\.gif|robots\.txt)$ [NC]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ server.php [L]
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_URI} !^/public/
RewriteRule ^(css|js|images)/(.*)$ public/$1/$2 [L,NC]
</IfModule>
Just save the .htaccess
file and that is all.
Rename your server.php
file to index.php
. that is all enjoy!
For years, I've tried to convince people that they needed to write unit test for their code. Whether they wrote the tests first (as in TDD) or after they coded the functionality, I always tried to explain them all the benefits of having unit tests for code. Hardly anyone disagreed with me. You cannot disagree with something that is obvious, and any smart person will see the benefits of unit test and TDD.
The problem with unit testing is that it requires a behavioral change, and it is very hard to change people's behavior. With words, you will get a lot of people to agree with you, but you won't see many changes in the way they do things.
You have to convince people by doing. Your personal success will atract more people than all the arguments you may have. If they see you are not just talking about unit test or TDD, but you are doing what you preach, and you are successful, people will try to imitate you.
You should also take on a lead role because no one writes unit test right the first time, so you may need to coach them on how to do it, show them the way, and the tools available to them. Help them while they write their first tests, review the tests they write on their own, and show them the tricks, idioms and patterns you've learned through your own experiences. After a while, they will start seeing the benefits on their own, and they will change their behavior to incorporate unit tests or TDD into their toolbox.
Changes won't happen over night, but with a little of patience, you may achieve your goal.
If you want to revert the file to its state in master
:
git checkout origin/master [filename]
Simply putting - this.setState({data: value}) is asynchronous in nature that means it moves out of the Call Stack and only comes back to the Call Stack unless it is resolved.
Please read about Event Loop to have a clear picture about Asynchronous nature in JS and why it takes time to update -
https://medium.com/front-end-weekly/javascript-event-loop-explained-4cd26af121d4
Hence -
this.setState({data:value});
console.log(this.state.data); // will give undefined or unupdated value
as it takes time to update. To achieve the above process -
this.setState({data:value},function () {
console.log(this.state.data);
});
Include the type specifier in your format expression:
>>> a = 10.1234
>>> f'{a:.2f}'
'10.12'
I know it's already answered but couldn't you just synchronize the settings in the settings designer to move back to your default settings?
You can also use the Package Manager Console and invoke the Install-Package
cmdlet by specifying the path to the directory that contains the package file in the -Source
parameter:
Install-Package SomePackage -Source C:\PathToThePackageDir\
If you just want, say, a head line and a content line, you can use:
git commit -m "My head line" -m "My content line."
Note that this creates separate paragraphs - not lines. So there will be a blank line between each two -m
lines, e.g.:
My head line
My content line.
You need to link the with the -lm
linker option
You need to compile as
gcc test.c -o test -lm
gcc (Not g++) historically would not by default include the mathematical functions while linking. It has also been separated from libc onto a separate library libm. To link with these functions you have to advise the linker to include the library -l
linker option followed by the library name m
thus -lm
.
The two queries express the same question. Apparently the query optimizer chooses two different execution plans. My guess would be that the distinct
approach is executed like:
business_key
values to a temporary tableThe group by
could be executed like:
business key
in a hashtableThe first method optimizes for memory usage: it would still perform reasonably well when part of the temporary table has to be swapped out. The second method optimizes for speed, but potentially requires a large amount of memory if there are a lot of different keys.
Since you either have enough memory or few different keys, the second method outperforms the first. It's not unusual to see performance differences of 10x or even 100x between two execution plans.
If you need local based string comparison, you can use strcoll
instead of strcmp
.
Remeber to first use setlocale
with LC_COLLATE
to set locale information if needed.
usort($your_data,function($a,$b){
setlocale (LC_COLLATE, 'pl_PL.UTF-8'); // Example of Polish language collation
return strcoll($a->name,$b->name);
});
You can get that error if you have an object with the same name as the schema. For example:
create sequence s2;
begin
s2.a;
end;
/
ORA-06550: line 2, column 6:
PLS-00302: component 'A' must be declared
ORA-06550: line 2, column 3:
PL/SQL: Statement ignored
When you refer to S2.MY_FUNC2
the object name is being resolved so it doesn't try to evaluate S2 as a schema name. When you just call it as MY_FUNC2
there is no confusion, so it works.
The documentation explains name resolution. The first piece of the qualified object name - S2 here - is evaluated as an object on the current schema before it is evaluated as a different schema.
It might not be a sequence; other objects can cause the same error. You can check for the existence of objects with the same name by querying the data dictionary.
select owner, object_type, object_name
from all_objects
where object_name = 'S2';
? 1. Can I set state inside a useEffect hook?
In principle, you can set state freely where you need it - including inside useEffect
and even during rendering. Just make sure to avoid infinite loops by settting Hook deps
properly and/or state conditionally.
? 2. Lets say I have some state that is dependent on some other state. Is it appropriate to create a hook that observes A and sets B inside the useEffect hook?
You just described the classic use case for useReducer
:
useReducer
is usually preferable touseState
when you have complex state logic that involves multiple sub-values or when the next state depends on the previous one. (React docs)When setting a state variable depends on the current value of another state variable, you might want to try replacing them both with
useReducer
. [...] When you find yourself writingsetSomething(something => ...)
, it’s a good time to consider using a reducer instead. (Dan Abramov, Overreacted blog)

? 3. Will the effects cascade such that, when I click the button, the first effect will fire, causing b to change, causing the second effect to fire, before the next render?
useEffect
always runs after the render is committed and DOM changes are applied. The first effect fires, changes b
and causes a re-render. After this render has completed, second effect will run due to b
changes.

? 4. Are there any performance downsides to structuring code like this?
Yes. By wrapping the state change of b
in a separate useEffect
for a
, the browser has an additional layout/paint phase - these effects are potentially visible for the user. If there is no way you want give useReducer
a try, you could change b
state together with a
directly:

Java implementations typically use a two-step compilation process. Java source code is compiled down to bytecode by the Java compiler. The bytecode is executed by a Java Virtual Machine (JVM). Modern JVMs use a technique called Just-in-Time (JIT) compilation to compile the bytecode to native instructions understood by hardware CPU on the fly at runtime.
Some implementations of JVM may choose to interpret the bytecode instead of JIT compiling it to machine code, and running it directly. While this is still considered an "interpreter," It's quite different from interpreters that read and execute the high level source code (i.e. in this case, Java source code is not interpreted directly, the bytecode, output of Java compiler, is.)
It is technically possible to compile Java down to native code ahead-of-time and run the resulting binary. It is also possible to interpret the Java code directly.
To summarize, depending on the execution environment, bytecode can be:
Open the file using vi or nano. and then press " i " ,
For save and quit
Enter Esc
and write the following command
:wq
without save and quit
:q!
The best way I have found to get a feel for things like this is to try them out:
import java.io.File;
public class PathTesting {
public static void main(String [] args) {
File f = new File("test/.././file.txt");
System.out.println(f.getPath());
System.out.println(f.getAbsolutePath());
try {
System.out.println(f.getCanonicalPath());
}
catch(Exception e) {}
}
}
Your output will be something like:
test\..\.\file.txt
C:\projects\sandbox\trunk\test\..\.\file.txt
C:\projects\sandbox\trunk\file.txt
So, getPath()
gives you the path based on the File object, which may or may not be relative; getAbsolutePath()
gives you an absolute path to the file; and getCanonicalPath()
gives you the unique absolute path to the file. Notice that there are a huge number of absolute paths that point to the same file, but only one canonical path.
When to use each? Depends on what you're trying to accomplish, but if you were trying to see if two Files
are pointing at the same file on disk, you could compare their canonical paths. Just one example.
A transaction is a way of representing a state change. Transactions ideally have four properties, commonly known as ACID:
See the Wikipedia ACID entry for more details.
Although this is typically applied to databases, it doesn't have to be. (In particular, see Software Transactional Memory.)
Assuming that yourObject.toString() returns "true" or "false", you can try
boolean b = Boolean.valueOf(yourObject.toString())
For me, none of these answers worked, but I finally found one that did.
I needed this for IE-
$('input:text').attr("disabled", 'disabled');
I also had to add this for Chrome and Firefox -
$('input:text').AddClass("notactive");
and this -
<style type="text/css">
.notactive {
pointer-events: none;
cursor: default;
}
</style>
<input type="button" />
buttons will not submit a form - they don't do anything by default. They're generally used in conjunction with JavaScript as part of an AJAX application.
<input type="submit">
buttons will submit the form they are in when the user clicks on them, unless you specify otherwise with JavaScript.
I Set variables in onCreate(), save scroll position in onPause() and set scroll position in onResume()
public static int index = -1;
public static int top = -1;
LinearLayoutManager mLayoutManager;
@Override
public void onCreate(Bundle savedInstanceState)
{
//Set Variables
super.onCreate(savedInstanceState);
cRecyclerView = ( RecyclerView )findViewById(R.id.conv_recycler);
mLayoutManager = new LinearLayoutManager(this);
cRecyclerView.setHasFixedSize(true);
cRecyclerView.setLayoutManager(mLayoutManager);
}
@Override
public void onPause()
{
super.onPause();
//read current recyclerview position
index = mLayoutManager.findFirstVisibleItemPosition();
View v = cRecyclerView.getChildAt(0);
top = (v == null) ? 0 : (v.getTop() - cRecyclerView.getPaddingTop());
}
@Override
public void onResume()
{
super.onResume();
//set recyclerview position
if(index != -1)
{
mLayoutManager.scrollToPositionWithOffset( index, top);
}
}
It looks like you probably pasted this (or used a word processor like MS Word) using a kind of double-quotes that are not recognized by the browser. Please check that your code uses actual double-quotes like this one "
, which is different from the following character: ”
Replace the meta tag with this one and try again:

Behavior difference: clicking in the space between label and input
If you click on the space between the label and the input it activates the input only if the label contains the input.
This makes sense since in this case the space is just another character of the label.
<p>Inside:</p>_x000D_
_x000D_
<label>_x000D_
<input type="checkbox" />_x000D_
|<----- Label. Click between me and the checkbox._x000D_
</label>_x000D_
_x000D_
<p>Outside:</p>_x000D_
_x000D_
<input type="checkbox" id="check" />_x000D_
<label for="check">|<----- Label. Click between me and the checkbox.</label>
_x000D_
Being able to click between label and box means that it is:
Bootstrap checkbox v3.3 examples use the input inside: http://getbootstrap.com/css/#forms Might be wise to follow them. But they changed their minds in v4.0 https://getbootstrap.com/docs/4.0/components/forms/#checkboxes-and-radios so I don't know what is wise anymore:
Checkboxes and radios use are built to support HTML-based form validation and provide concise, accessible labels. As such, our
<input>
s and<label>
s are sibling elements as opposed to an<input>
within a<label>
. This is slightly more verbose as you must specify id and for attributes to relate the<input>
and<label>
.

Welcome to the concept of the pointer. Generations of beginning programmers have found the concept elusive, but if you wish to grow into a competent programmer, you must eventually master this concept — and moreover, you are already asking the right question. That's good.
Is it clear to you what an address is? See this diagram:
---------- ----------
| 0x4000 | | 0x4004 |
| 1 | | 7 |
---------- ----------
In the diagram, the integer 1 is stored in memory at address 0x4000. Why at an address? Because memory is large and can store many integers, just as a city is large and can house many families. Each integer is stored at a memory location, as each family resides in a house. Each memory location is identified by an address, as each house is identified by an address.
The two boxes in the diagram represent two distinct memory locations. You can think of them as if they were houses. The integer 1 resides in the memory location at address 0x4000 (think, "4000 Elm St."). The integer 7 resides in the memory location at address 0x4004 (think, "4004 Elm St.").
You thought that your program was comparing the 1 to the 7, but it wasn't. It was comparing the 0x4000 to the 0x4004. So what happens when you have this situation?
---------- ----------
| 0x4000 | | 0x4004 |
| 1 | | 1 |
---------- ----------
The two integers are the same but the addresses differ. Your program compares the addresses.
To pass the parameter you need to use resolve and inject the items in controller
$scope.Edit = function (Id) {
var modalInstance = $modal.open({
templateUrl: '/app/views/admin/addeditphone.html',
controller: 'EditCtrl',
resolve: {
editId: function () {
return Id;
}
}
});
}
Now if you will use like this:
app.controller('EditCtrl', ['$scope', '$location'
, function ($scope, $location, editId)
in this case editId will be undefined. You need to inject it, like this:
app.controller('EditCtrl', ['$scope', '$location', 'editId'
, function ($scope, $location, editId)
Now it will work smooth, I face the same problem many time, once injected, everything start working!
I have the same problem that I found some color in form of #AAAAAA
and I want to conver that into a form that android could make use of.
I found that you can just use 0xFFAAAAAA
so that android could automatically tell the color. Notice the first FF
is telling alpha
value.
Hope it helps
The answer I got is that variables and subqueries will not work and we have to user dynamic SQL script. The following works:
DECLARE @SQL VARCHAR(4000)
SET @SQL = 'ALTER TABLE dbo.Student DROP CONSTRAINT |ConstraintName| '
SET @SQL = REPLACE(@SQL, '|ConstraintName|', ( SELECT name
FROM sysobjects
WHERE xtype = 'PK'
AND parent_obj = OBJECT_ID('Student')))
EXEC (@SQL)
I ran into the same issue with CLion 1.2.1 (at the time of writing this answer) after updating Windows 10. It was working fine before I had updated my OS. My OS is installed in C:\ drive and CLion 1.2.1 and Cygwin (64-bit) are installed in D:\ drive.
The issue seems to be with CMake. I am using Cygwin. Below is the short answer with steps I used to fix the issue.
SHORT ANSWER (should be similar for MinGW too but I haven't tried it):
LONG ANSWER:
Below are the detailed steps that solved this issue for me:
Uninstall/delete the previous version of Cygwin (MinGW in your case)
Make sure that CLion is up-to-date
Run Cygwin setup (x64 for my 64-bit OS)
Install at least the following packages for Cygwin:
gcc
g++
make
Cmake
gdb
Make sure you are installing the correct versions of the above packages that CLion requires. You can find the required version numbers at CLion's Quick Start section (I cannot post more than 2 links until I have more reputation points).
Next, you need to add Cygwin (or MinGW) to your Windows Environment Variable called 'Path'. You can Google how to find environment variables for your version of Windows
[On Win 10, right-click on 'This PC' and select Properties -> Advanced system settings -> Environment variables... -> under 'System Variables' -> find 'Path' -> click 'Edit']
Add the 'bin' folder to the Path variable. For Cygwin, I added:
D:\cygwin64\bin
Start CLion and go to 'Settings' either from the 'Welcome Screen' or from File -> Settings
Select 'Build, Execution, Deployment' and then click on 'Toolchains'
Your 'Environment' should show the correct path to your Cygwin installation directory (or MinGW)
For 'CMake executable', select 'Use bundled CMake x.x.x' (3.3.2 in my case at the time of writing this answer)
'Debugger' shown to me says 'Cygwin GDB GNU gdb (GDB) 7.8' [too many gdb's in that line ;-)]
Below that it should show a checkmark for all the categories and should also show the correct path to 'make', 'C compiler' and 'C++ compiler'
See screenshot: Check all paths to the compiler, make and gdb
See screenshot: Check the configuration to run the project
There should be no errors in the console window. You will see that the 'Run' -> 'Build' option is now active
Build your project and then run the project. You should see the output in the terminal window
Hope this helps! Good luck and enjoy CLion.

You can use a watchpoint for this (A breakpoint on data instead of code).
You can start by using watch i
.
Then set a condition for it using condition <breakpoint num> i == 5
You can get the breakpoint number by using info watch
you can apply awk to many situations
echo "[email protected];[email protected]"|awk -F';' '{printf "%s\n%s\n", $1, $2}'
also you can use this
echo "[email protected];[email protected]"|awk -F';' '{print $1,$2}' OFS="\n"
If you like to avoid both changes()=0
and INSERT OR IGNORE
even if you cannot afford deleting the row - You can use this logic;
First, insert (if not exists) and then update by filtering with the unique key.
-- Table structure
CREATE TABLE players (
id INTEGER PRIMARY KEY AUTOINCREMENT,
user_name VARCHAR (255) NOT NULL
UNIQUE,
age INTEGER NOT NULL
);
-- Insert if NOT exists
INSERT INTO players (user_name, age)
SELECT 'johnny', 20
WHERE NOT EXISTS (SELECT 1 FROM players WHERE user_name='johnny' AND age=20);
-- Update (will affect row, only if found)
-- no point to update user_name to 'johnny' since it's unique, and we filter by it as well
UPDATE players
SET age=20
WHERE user_name='johnny';
Notice: I haven't tested it to see the which triggers are being called, but I assume the following:
in this way you can have a single SQL command
-- Table structure
CREATE TABLE players (
id INTEGER PRIMARY KEY AUTOINCREMENT,
user_name VARCHAR (255) NOT NULL
UNIQUE,
age INTEGER NOT NULL
);
-- Single command to insert or update
INSERT OR REPLACE INTO players
(id, user_name, age)
VALUES ((SELECT id from players WHERE user_name='johnny' AND age=20),
'johnny',
20);
Edit: added option 2.
df2 <- data.frame(apply(df1, 2, function(x) as.numeric(as.character(x))))
I was having same error using DownloadString; and was able to make it works as below with suggestions on this page
System.Net.WebClient client = new System.Net.WebClient();
ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
string sHttpResonse = client.DownloadString(sUrl);
Try this:
function add()

var inputs = document.getElementsByTagName("input");
for(i = 0; i <= inputs.length; i++)
{
if( inputs[i].name == 'qty'+i)

}
}
console.log(sum)

The question was how to copy a folder from remote to local with scp
command.
$ scp -r userRemote@remoteIp:/path/remoteDir /path/localDir
But here is the better way for do it with sftp
- SSH File Transfer Protocol (also Secure File Transfer Protocol, or SFTP) is a network protocol that provides file access, file transfer, and file management over any reliable data stream.(wikipedia).
$ sftp user_remote@remote_ip
sftp> cd /path/to/remoteDir
sftp> get -r remoteDir
Fetching /path/to/remoteDir to localDir 100% 398 0.4KB/s 00:00
For help about sftp
command just type help

They are binding to keydown in the autocomplete source, so triggering the keydown will case it to update.
$("#CompanyList").trigger('keydown');
They aren't binding to the 'change' event because that only triggers at the DOM level when the form field loses focus. The autocomplete needs to respond faster than 'lost focus' so it has to bind to a key event.
Doing this:
companyList.autocomplete('option','change').call(companyList);
Will cause a bug if the user retypes the exact option that was there before.
To avoid the boxing of KeyValuePair.Equals(object)
you can use a ValueTuple
.
if ((getResult.Key, getResult.Value) == default)

delegate:nil //or self
cancelButtonTitle:@"OK"
otherButtonTitles:nil];

[alert autorelease];
Note : Use it if calculating / adding days from current date.
Be aware: this answer has issues (see comments)
var myDate = new Date();
myDate.setDate(myDate.getDate() + AddDaysHere);
It should be like
var newDate = new Date(date.setTime( date.getTime() + days * 86400000 ));
Use GET method if you want to retrieve the resources from URL. You could always see the last page if you hit the back button of your browser, and it could be bookmarked, so it is not as secure as POST method.
Use POST method if you want to 'submit' something to the URL. For example you want to create a google account and you may need to fill in all the detailed information, then you hit 'submit' button (POST method is called here), once you submit successfully, and try to hit back button of your browser, you will get error or a new blank form, instead of last page with filled form.
A simple trick to change a particular point marker shape, size... is to first plot it with all the other data then plot one more plot only with that point (or set of points if you want to change the style of multiple points). Suppose we want to change the marker shape of second point:
x = [1,2,3,4,5]
y = [2,1,3,6,7]
plt.plot(x, y, "-o")
x0 = [2]
y0 = [1]
plt.plot(x0, y0, "s")
plt.show()
Result is: Plot with multiple markers
Redux can't return a function instead of an action. It's just a fact. That's why people use Thunk. Read these 14 lines of code to see how it allows the async cycle to work with some added function layering:
function createThunkMiddleware(extraArgument) {
return ({ dispatch, getState }) => (next) => (action) => {
if (typeof action === 'function') {
return action(dispatch, getState, extraArgument);
}
return next(action);
};
}
const thunk = createThunkMiddleware();
thunk.withExtraArgument = createThunkMiddleware;
export default thunk;
Try this test:
any(substring in string for substring in substring_list)
It will return True
if any of the substrings in substring_list
is contained in string
.
Note that there is a Python analogue of Marc Gravell's answer in the linked question:
from itertools import imap
any(imap(string.__contains__, substring_list))
In Python 3, you can use map
directly instead:
any(map(string.__contains__, substring_list))
Probably the above version using a generator expression is more clear though.
Try this
import csv, json, sys
input = open(sys.argv[1])
data = json.load(input)
input.close()
output = csv.writer(sys.stdout)
output.writerow(data[0].keys()) # header row
for item in data:
output.writerow(item.values())
You need to add the MVC-specific Razor configuration to your web.config. See here: Razor HtmlHelper Extensions (or other namespaces for views) Not Found
Use the MVC 3 upgrade tool to automatically ensure you have the right config values.
Assuming your products LINQ class uses a similar yield for enumerating/iterating, the first version is more efficient because its only yielding one value each time its iterated over.
The second example is converting the enumerator/iterator to a list with the ToList() method. This means it manually iterates over all the items in the enumerator and then returns a flat list.
There also is XML schema learner
which is available on Github.
It can take multiple xml files and extract a common XSD from all of those files.
You have several options
integer(3)
numeric(3)
rep(0, 3)
rep(0L, 3)
What do you mean, the error only shows up when you assign? For example on GCC, with no assignment in sight:
int main() {
struct blah *b = 0;
*b; // this is line 6
}
incompletetype.c:6: error: dereferencing pointer to incomplete type
.
The error is at line 6, that's where I used an incomplete type as if it were a complete type. I was fine up until then.
The mistake is that you should have included whatever header defines the type. But the compiler can't possibly guess what line that should have been included at: any line outside of a function would be fine, pretty much. Neither is it going to go trawling through every text file on your system, looking for a header that defines it, and suggest you should include that.
Alternatively (good point, potatoswatter), the error is at the line where b
was defined, when you meant to specify some type which actually exists, but actually specified blah
. Finding the definition of the variable b
shouldn't be too difficult in most cases. IDEs can usually do it for you, compiler warnings maybe can't be bothered. It's some pretty heinous code, though, if you can't find the definitions of the things you're using.
With the YouTube video updated as of June 2020 it's very straight forward
You will get and .sbv file
Got this problem to, and finaly, I build myself a short solution. You just have to ellipsize manually the line you want, your maxLine attribute will cut your text.
This example cut your text for 3 lines max
final TextView title = (TextView)findViewById(R.id.text);
title.setText("A really long text");
ViewTreeObserver vto = title.getViewTreeObserver();
vto.addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
ViewTreeObserver obs = title.getViewTreeObserver();
obs.removeGlobalOnLayoutListener(this);
if(title.getLineCount() > 3){
Log.d("","Line["+title.getLineCount()+"]"+title.getText());
int lineEndIndex = title.getLayout().getLineEnd(2);
String text = title.getText().subSequence(0, lineEndIndex-3)+"...";
title.setText(text);
Log.d("","NewText:"+text);
}
}
});
I had the same problem.
I've installed fresh mysql at Ubuntu but I left mysql password empty, and as a result I couldn't connect to mysql in any way.
Lately I've revealed that there is a table of users where are names, hosts, passwords and some plugins. So for my user root@localhost mysql while installing assigned a plugin called auth_socket, which let Unix user "root" log in as a mysql user "root" without password, but don't allow login as another Unix user. So to fix that you should turn off this plugin and set usual authentication:

Since Python 3.5, things are much easier with os.scandir()
with os.scandir(path) as it:
for entry in it:
if entry.name.endswith(".asm") and entry.is_file():
print(entry.name, entry.path)
Using scandir() instead of listdir() can significantly increase the performance of code that also needs file type or file attribute information, because os.DirEntry objects expose this information if the operating system provides it when scanning a directory. All os.DirEntry methods may perform a system call, but is_dir() and is_file() usually only require a system call for symbolic links; os.DirEntry.stat() always requires a system call on Unix but only requires one for symbolic links on Windows.

The problem is that you're not initializing the pointer. You've created a pointer to "anywhere you want"—which could be the address of some other variable, or the middle of your code, or some memory that isn't mapped at all.
You need to create an int
variable somewhere in memory for the int *
variable to point at.
Your second example does this, but it does other things that aren't relevant here. Here's the simplest thing you need to do:
int main(){
int variable;
int *ptr = &variable;
*ptr = 20;
printf("%d", *ptr);
return 0;
}
Here, the int
variable isn't initialized—but that's fine, because you're just going to replace whatever value was there with 20
. The key is that the pointer is initialized to point to the variable
. In fact, you could just allocate some raw memory to point to, if you want:
int main(){
void *memory = malloc(sizeof(int));
int *ptr = (int *)memory;
*ptr = 20;
printf("%d", *ptr);
free(memory);
return 0;
}
You can create an AppleScript file to open Eclipse with a given workspace. You can even save the AppleScript file as an Application, which is equivalent to creating an alias with arguments in Windows OS.
Open Script Editor and type the following:
do shell script "open '/path/to/your/Eclipse/installation' -n --args -data /path/to/your/workspace"
For instance:
do shell script "open '/Applications/Eclipse.app' -n --args -data /MyWorkspaces/Personal"
Press the Run button to check it's working.
This script can be saved as such, but I prefer to save it as an Application. That way I can customize the icon by copying the *.icns icon from the original Eclipse.app bundle to the script application bundle.
To open an App folder, use the "see contents" contextual menu option. It should look like this:
Where "main.scpt" is the AppleScript file and "applet.icns" is the icon from the original Eclipse bundle.

The Denver SQL Server Users group has had some really good presentations over the last couple of months on the new features in SQL 2008 including one from Paul Nielsen just last week shortly after he got back from "Jump Start" up in Redmond (if I remember the name of the event correctly).
A couple of caveats on all of the "new features" for SQL 2008, the triage to determine which features will be in the various editions is still in progress. Many/most of the new/very cool features like data compression, partitioned indexes, policies, etc. are only going to be in the enterprise edition. Unless you're planning on running enterprise edition a lot of the features that are in the CTP's will probably not be in SQL 2008 standard, etc.
On other minor but often overlooked issue - SQL 2008 will only be 64-bit, if you're buying new hardware shouldn't be an issue but if you're planning on using existing hardware... also, if you've got dependencies on third party drivers (e.g. oracle) best be sure that a 64-bit version is available/works
To remove a timezone (tzinfo) from a datetime object:
# dt_tz is a datetime.datetime object
dt = dt_tz.replace(tzinfo=None)
If you are using a library like arrow, then you can remove timezone by simply converting an arrow object to to a datetime object, then doing the same thing as the example above.
# <Arrow [2014-10-09T10:56:09.347444-07:00]>
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')
# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444, tzinfo=tzoffset(None, -25200))
tmpDatetime = arrowObj.datetime
# datetime.datetime(2014, 10, 9, 10, 56, 9, 347444)
tmpDatetime = tmpDatetime.replace(tzinfo=None)
Why would you do this? One example is that mysql does not support timezones with its DATETIME type. So using ORM's like sqlalchemy will simply remove the timezone when you give it a datetime.datetime
object to insert into the database. The solution is to convert your datetime.datetime
object to UTC (so everything in your database is UTC since it can't specify timezone) then either insert it into the database (where the timezone is removed anyway) or remove it yourself. Also note that you cannot compare datetime.datetime
objects where one is timezone aware and another is timezone naive.
##############################################################################
# MySQL example! where MySQL doesn't support timezones with its DATETIME type!
##############################################################################
arrowObj = arrow.get('2014-10-09T10:56:09.347444-07:00')
arrowDt = arrowObj.to("utc").datetime
# inserts datetime.datetime(2014, 10, 9, 17, 56, 9, 347444, tzinfo=tzutc())
insertIntoMysqlDatabase(arrowDt)
# returns datetime.datetime(2014, 10, 9, 17, 56, 9, 347444)
dbDatetimeNoTz = getFromMysqlDatabase()
# cannot compare timzeone aware and timezone naive
dbDatetimeNoTz == arrowDt # False, or TypeError on python versions before 3.3
# compare datetimes that are both aware or both naive work however
dbDatetimeNoTz == arrowDt.replace(tzinfo=None) # True
Also, you can use shelljs
plugin.
It's easy and it's cross-platform.
Install command:
npm install [-g] shelljs
What is shellJS
ShellJS is a portable (Windows/Linux/OS X) implementation of Unix shell commands on top of the Node.js API. You can use it to eliminate your shell script's dependency on Unix while still keeping its familiar and powerful commands. You can also install it globally so you can run it from outside Node projects - say goodbye to those gnarly Bash scripts!
An example of how it works:
var shell = require('shelljs');
if (!shell.which('git')) {
shell.echo('Sorry, this script requires git');
shell.exit(1);
}
// Copy files to release dir
shell.rm('-rf', 'out/Release');
shell.cp('-R', 'stuff/', 'out/Release');
// Replace macros in each .js file
shell.cd('lib');
shell.ls('*.js').forEach(function (file) {
shell.sed('-i', 'BUILD_VERSION', 'v0.1.2', file);
shell.sed('-i', /^.*REMOVE_THIS_LINE.*$/, '', file);
shell.sed('-i', /.*REPLACE_LINE_WITH_MACRO.*\n/, shell.cat('macro.js'), file);
});
shell.cd('..');
// Run external tool synchronously
if (shell.exec('git commit -am "Auto-commit"').code !== 0) {
shell.echo('Error: Git commit failed');
shell.exit(1);
}
Also, you can use from the command line:
$ shx mkdir -p foo
$ shx touch foo/bar.txt
$ shx rm -rf foo
For PHP, Java, C++, C, Perl, JavaScript, CSS you can try:
I am posting an answer here, since I had the same error message for a different reason.
This error message can happen, for example, if you are using apache httpd to proxy requests from a source on protocol A to target on protocol B.
Here is the example of my situation:
AH01144: No protocol handler was valid for the URL /sockjs-node/info (scheme 'ws').
In the case above, what was happening was simply the following. I had enabled mod proxy to proxy websocket requests to nodejs based on path /sockjs-node.
The problem is that node does not use the path /sockjs-node for websocket requests exclusively. It also uses this path for hosting REST entrypoints that deliver information about websockets.
In this manner, when the application would try to open http://localhost:7001/sockjs-node/info, apache httpd would be trying to route the rest call from HTTP protocol to to a Webscoket endpoint call. Node did not accept this.
This lead to the exception above.
So be mindful that even if you enable the right modules, if you try to do the wrong forwarding, this will end with apache httpd informing you that the protocol you tried to use on the target server is not valid.
In addition, it is also possible to turn logging off programmatically:
Logger.getRootLogger().setLevel(Level.OFF);
Or
Logger.getRootLogger().removeAllAppenders();
Logger.getRootLogger().addAppender(new NullAppender());

import org.apache.log4j.Level;
import org.apache.log4j.NullAppender;
Methods for sanitizing user input with PHP:
$mysqli->set_charset("utf8");manual

$pdo->exec("set names utf8");manual
$pdo = new PDO( "mysql:host=$host;dbname=$db", $user, $pass, array( PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION, PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8" ) );manual
[deprecated in PHP 5.5.0, removed in PHP 7.0.0].mysql_set_charset('utf8')
$stmt = $mysqli->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$param = "' OR 1=1 /*";
$stmt->bind_param('s', $param);
$stmt->execute();
PDO::quote() - places quotes around the input string (if required) and escapes special characters within the input string, using a quoting style appropriate to the underlying driver:
$pdo = new PDO('mysql:host=localhost;dbname=testdb;charset=UTF8', $user, $password);explicit set the character set
$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);disable emulating prepared statements to prevent fallback to emulating statements that MySQL can't prepare natively (to prevent injection)
$var = $pdo->quote("' OR 1=1 /*");not only escapes the literal, but also quotes it (in single-quote ' characters) $stmt = $pdo->query("SELECT * FROM test WHERE name = $var LIMIT 1");
PDO Prepared Statements: vs MySQLi prepared statements supports more database drivers and named parameters:
$pdo = new PDO('mysql:host=localhost;dbname=testdb;charset=UTF8', $user, $password);explicit set the character set
$pdo->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);disable emulating prepared statements to prevent fallback to emulating statements that MySQL can't prepare natively (to prevent injection) $stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1'); $stmt->execute(["' OR 1=1 /*"]);

Another info: If you want use a Route Constraint, imagine that you want force that parameter has int datatype, then you need use this syntax:
[Route("v1/location/**{deviceOrAppid:int?}**", Name = "AddNewLocation")]
The ? character is put always before the last } character
For more information see: Optional URI Parameters and Default Values
Try this way.
public static bool hasSpecialChar(string input)
{
string specialChar = @"\|!#$%&/()=?»«@£§€{}.-;'<>_,";
foreach (var item in specialChar)
{
if (input.Contains(item)) return true;
}
return false;

As TASKKILL might be unavailable on some Home/basic editions of windows here some alternatives:
TSKILL processName
or
TSKILL PID
Have on mind that processName
should not have the .exe
suffix and is limited to 18 characters.
Another option is WMIC
:
wmic Path win32_process Where "Caption Like 'MyProcess.exe'" Call Terminate
wmic offer even more flexibility than taskkill .With wmic Path win32_process get
you can see the available fileds you can filter.
Use this method:
private Long secondsBetween(Date first, Date second){

For future readers, here is an elegant solution(5x5):
var matrix = [[Int]](repeating: [Int](repeating: 0, count: 5), count: 5)
and a dynamic approach:
var matrix = [[Int]]() // creates an empty matrix
var row = [Int]() // fill this row
matrix.append(row) // add this row
Check if have a python interpreter alive in any of the terminal windows. If so kill it and try sudo pip
which worked for me.
There's no need to manually set the colors. Instead, specify a grayscale colormap...
import numpy as np
import matplotlib.pyplot as plt
# Generate data...
x = np.random.random(10)
y = np.random.random(10)
# Plot...
plt.scatter(x, y, c=y, s=500)
plt.gray()
plt.show()
Or, if you'd prefer a wider range of colormaps, you can also specify the cmap
kwarg to scatter
. To use the reversed version of any of these, just specify the "_r
" version of any of them. E.g. gray_r
instead of gray
. There are several different grayscale colormaps pre-made (e.g. gray
, gist_yarg
, binary
, etc).
import matplotlib.pyplot as plt
import numpy as np
# Generate data...
x = np.random.random(10)
y = np.random.random(10)
plt.scatter(x, y, c=y, s=500, cmap='gray')
plt.show()
Your question is mixing a few different concepts. You started out saying you wanted to run sites on the same server using the same domain, but in different folders. That doesn't require any special setup. Once you get the single domain running, you just create folders under that docroot.
Based on the rest of your question, what you really want to do is run various sites on the same server with their own domain names.
The best documentation you'll find on the topic is the virtual host documentation in the apache manual.
There are two types of virtual hosts: name-based and IP-based. Name-based allows you to use a single IP address, while IP-based requires a different IP for each site. Based on your description above, you want to use name-based virtual hosts.
The initial error you were getting was due to the fact that you were using different ports than the NameVirtualHost
line. If you really want to have sites served from ports other than 80, you'll need to have a NameVirtualHost
entry for each port.
Assuming you're starting from scratch, this is much simpler than it may seem.
If you are using 2.3 or earlier, the first thing you need to do is tell Apache that you're going to use name-based virtual hosts.
NameVirtualHost *:80
If you are using 2.4 or later do not add a NameVirtualHost line. Version 2.4 of Apache deprecated the NameVirtualHost
directive, and it will be removed in a future version.
Now your vhost definitions:
<VirtualHost *:80>
DocumentRoot "/home/user/site1/"
ServerName site1
</VirtualHost>
<VirtualHost *:80>
DocumentRoot "/home/user/site2/"
ServerName site2
</VirtualHost>
You can run as many sites as you want on the same port. The ServerName
being different is enough to tell Apache which vhost to use. Also, the ServerName
directive is always the domain/hostname and should never include a path.
If you decide to run sites on a port other than 80, you'll always have to include the port number in the URL when accessing the site. So instead of going to http://example.com you would have to go to http://example.com:81
SELECT *
FROM tbl
WHERE id = 1
ORDER BY signin DESC
LIMIT 1;
The obvious index would be on (id)
, or a multicolumn index on (id, signin DESC)
.
Conveniently for the case, MySQL sorts NULL
values last in descending order. That's what you typically want if there can be NULL
values: the row with the latest not-null signin
.
To get NULL
values first:
ORDER BY signin IS NOT NULL, signin DESC
You may want to append more expressions to ORDER BY
to get a deterministic pick from (potentially) multiple rows with NULL
.
The same applies without NULL
if signin
is not defined UNIQUE
.

The SQL standard does not explicitly define a default sort order for NULL
values. The behavior varies quite a bit across different RDBMS. See:
But there are the NULLS FIRST
/ NULLS LAST
clauses defined in the SQL standard and supported by most major RDBMS, but not by MySQL. See:
My answer is similar to Alex's. I'm not sure why React-Router made this so needlessly complicated. Why should I have to wrap my component with a HoC just to get access to what's essentially a global?
Anyway, if you take a look at how they implemented <BrowserRouter>
, it's just a tiny wrapper around history.
We can pull that history bit out so that we can import it from anywhere. The trick, however, is if you're doing server-side rendering and you try to import
the history module, it won't work because it uses browser-only APIs. But that's OK because we usually only redirect in response to a click or some other client-side event. Thus it's probably OK to fake it:
// history.js
if(__SERVER__) {
module.exports = {};
} else {
module.exports = require('history').createBrowserHistory();
}
With the help of webpack, we can define some vars so we know what environment we're in:
plugins: [
new DefinePlugin({
'__SERVER__': 'false',
'__BROWSER__': 'true', // you really only need one of these, but I like to have both
}),
And now you can
import history from './history';
From anywhere. It'll just return an empty module on the server.
If you don't want use these magic vars, you'll just have to require
in the global object where it's needed (inside your event handler). import
won't work because it only works at the top-level.
Do you mean, for concatenation?
Real world example: You want to create a new string out of many others.
For instance to send a message:
String
String s = "Dear " + user.name + "<br>" +
" I saw your profile and got interested in you.<br>" +
" I'm " + user.age + "yrs. old too"
StringBuilder
String s = new StringBuilder().append.("Dear ").append( user.name ).append( "<br>" )
.append(" I saw your profile and got interested in you.<br>")
.append(" I'm " ).append( user.age ).append( "yrs. old too")
.toString()
Or
String s = new StringBuilder(100).appe..... etc. ...
// The difference is a size of 100 will be allocated upfront as fuzzy lollipop points out.
StringBuffer ( the syntax is exactly as with StringBuilder, the effects differ )
About
StringBuffer
vs. StringBuilder
The former is synchonized and later is not.
So, if you invoke it several times in a single thread ( which is 90% of the cases ), StringBuilder
will run much faster because it won't stop to see if it owns the thread lock.
So, it is recommendable to use StringBuilder
( unless of course you have more than one thread accessing to it at the same time, which is rare )
String
concatenation ( using the + operator ) may be optimized by the compiler to use StringBuilder
underneath, so, it not longer something to worry about, in the elder days of Java, this was something that everyone says should be avoided at all cost, because every concatenation created a new String object. Modern compilers don't do this anymore, but still it is a good practice to use StringBuilder
instead just in case you use an "old" compiler.
edit
Just for who is curious, this is what the compiler does for this class:
class StringConcatenation {
int x;
String literal = "Value is" + x;
String builder = new StringBuilder().append("Value is").append(x).toString();
}
javap -c StringConcatenation
Compiled from "StringConcatenation.java"
class StringConcatenation extends java.lang.Object{
int x;
java.lang.String literal;
java.lang.String builder;
StringConcatenation();

Lines numbered 5 - 27 are for the String named "literal"
Lines numbered 31-53 are for the String named "builder"
Ther's no difference, exactly the same code is executed for both strings.

Notice I have this in a class lib, so thus the "self::validate_phone_number" call from the first function/method.
Notice line # 32 of the "validate_phone_number" function where I added the:
if ( !$valid['format'] ) {
return false;
} else {
to get me the false return needed if not valid phone number.
Still need to test this against more data, but working on current data, with current format and I'm using style '8' for this particular data batch.
Also I commented out the "extension" logic as I was constantly getting errors from it, seeing I do not have any of that info in my data.
The above answers missing a way to find the realm file in Android platform and believe me this way will save your lot's of time which we generally waste in other approaches to get the realm file. So let's start...
First open "Device File Explorer" in android studio(View -> Tools Windows -> Device File Explorer.
This will open your device explorer.
now open data -> data -> (your_app_package_name) -> files -> default.realm
default.realm is the file for which we are here. Now Save_as this file at your location and access the file from the realm_browser and you will get your database.
NOTE: Mentioned approach is tested on non-rooted phone(one+3).
hdfs dfs -count <dir>
info from man page:
-count [-q] [-h] [-v] [-t [<storage type>]] [-u] <path> ... :
Count the number of directories, files and bytes under the paths
that match the specified file pattern. The output columns are:
DIR_COUNT FILE_COUNT CONTENT_SIZE PATHNAME
or, with the -q option:
QUOTA REM_QUOTA SPACE_QUOTA REM_SPACE_QUOTA
DIR_COUNT FILE_COUNT CONTENT_SIZE PATHNAME
As mentioned in "Polling must die: triggering Jenkins builds from a git hook", you can notify Jenkins of a new commit:
With the latest Git plugin 1.1.14 (that I just release now), you can now do this more >easily by simply executing the following command:
curl http://yourserver/jenkins/git/notifyCommit?url=<URL of the Git repository>
This will scan all the jobs that’s configured to check out the specified URL, and if they are also configured with polling, it’ll immediately trigger the polling (and if that finds a change worth a build, a build will be triggered in turn.)
This allows a script to remain the same when jobs come and go in Jenkins.
Or if you have multiple repositories under a single repository host application (such as Gitosis), you can share a single post-receive hook script with all the repositories. Finally, this URL doesn’t require authentication even for secured Jenkins, because the server doesn’t directly use anything that the client is sending. It runs polling to verify that there is a change, before it actually starts a build.
As mentioned here, make sure to use the right address for your Jenkins server:
since we're running Jenkins as standalone Webserver on port 8080 the URL should have been without the
/jenkins
, like this:http://jenkins:8080/git/notifyCommit?url=git@gitserver:tools/common.git
To reinforce that last point, ptha adds in the comments:
It may be obvious, but I had issues with:
curl http://yourserver/jenkins/git/notifyCommit?url=<URL of the Git repository>.
The url parameter should match exactly what you have in Repository URL of your Jenkins job.
When copying examples I left out the protocol, in our casessh://
, and it didn't work.
You can also use a simple post-receive hook like in "Push based builds using Jenkins and GIT"
#!/bin/bash
/usr/bin/curl --user USERNAME:PASS -s \
http://jenkinsci/job/PROJECTNAME/build?token=1qaz2wsx
Configure your Jenkins job to be able to “Trigger builds remotely” and use an authentication token (
1qaz2wsx
in this example).
However, this is a project-specific script, and the author mentions a way to generalize it.
The first solution is easier as it doesn't depend on authentication or a specific project.
I want to check in change set whether at least one java file is there the build should start.
Suppose the developers changed only XML files or property files, then the build should not start.
Basically, your build script can:
git notes
) on the first callHEAD
of your branch candidate for build and the commit referenced by the git notes
'build' (git show refs/notes/build
): git diff --name-only SHA_build HEAD
.git notes
'build
' to HEAD
.May 2016: cwhsu points out in the comments the following possible url:
you could just use
curl --user USER:PWD http://JENKINS_SERVER/job/JOB_NAME/build?token=YOUR_TOKEN
if you set trigger config in your item
June 2016, polaretto points out in the comments:
I wanted to add that with just a little of shell scripting you can avoid manual url configuration, especially if you have many repositories under a common directory.
For example I used these parameter expansions to get the repo namerepository=${PWD%/hooks}; repository=${repository##*/}
and then use it like:
curl $JENKINS_URL/git/notifyCommit?url=$GIT_URL/$repository
So all you need to do for this to work is add:
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json'
}
as a field to your post request and it'll work.
In Rails 4, this is a better (DRYer) solution:
change_column_null :my_models, :date_column, false
To ensure no records exist with NULL
values in that column, you can pass a fourth parameter, which is the default value to use for records with NULL
values:
change_column_null :my_models, :date_column, false, Time.now
I had a similar issue when trying to access a service (old ASMX service). The call would work when accessing via an IP however when calling with an alias I would get the remote name could not be resolved.
Added the following to the config and it resolved the issue:
<system.net>
<defaultProxy enabled="true">
</defaultProxy>
</system.net>
On BS3
.tooltip-inner {
min-width: 150px; /* the minimum width */
}
You can call [aDictionary description], or anywhere you would need a format string, just use %@ to stand in for the dictionary:
[NSString stringWithFormat:@"my dictionary is %@", aDictionary];
or
NSLog(@"My dictionary is %@", aDictionary);
One thing where didSet
is really handy is when you use outlets to add additional configuration.
@IBOutlet weak var loginOrSignupButton: UIButton! {
didSet {
let title = NSLocalizedString("signup_required_button")
loginOrSignupButton.setTitle(title, for: .normal)
loginOrSignupButton.setTitle(title, for: .highlighted)
}
It happens when Xcode doesn't recognize your certificate.
It's just a pain in the ass to solve it, there are a lot of possibilities to help you.
But the first thing you should try is removing in the "Window" tab => Organizer, the provisioning that is in your device. Then re-add them (download them again on the apple website). And try to compile again.
By the way, did you check in the Project Info Window the "code signing identity" ?
Good Luck.
you can use
display: table;
for your container and therfore avoid the overflow: hidden;
. It should do the job if you used it just for warpping purpose.
This error means that length of index index
is more then 1000 bytes. MySQL and storage engines may have this restriction. I have got similar error on MySQL 5.5 - 'Specified key was too long; max key length is 3072 bytes' when ran this script:
CREATE TABLE IF NOT EXISTS test_table1 (
column1 varchar(500) NOT NULL,
column2 varchar(500) NOT NULL,
column3 varchar(500) NOT NULL,
column4 varchar(500) NOT NULL,
column5 varchar(500) NOT NULL,
column6 varchar(500) NOT NULL,
KEY `index` (column1, column2, column3, column4, column5, column6)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
UTF8 is multi-bytes, and key length is calculated in this way - 500 * 3 * 6 = 9000 bytes.
But note, next query works!
CREATE TABLE IF NOT EXISTS test_table1 (
column1 varchar(500) NOT NULL,
column2 varchar(500) NOT NULL,
column3 varchar(500) NOT NULL,
column4 varchar(500) NOT NULL,
column5 varchar(500) NOT NULL,
column6 varchar(500) NOT NULL,
KEY `index` (column1, column2, column3, column4, column5, column6)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
...because I used CHARSET=latin1, in this case key length is 500 * 6 = 3000 bytes.
Assuming every dict has a value
key, you can write (assuming your list is named l
)
[d['value'] for d in l]
If value
might be missing, you can use
[d['value'] for d in l if 'value' in d]

Original Answer
As answered on other question, you need to use original onMeasure() method when your recycler view height is bigger than screen height. This layout manager can calculate ItemDecoration and can scroll with more.
public class MyLinearLayoutManager extends LinearLayoutManager {
public MyLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
super(context, orientation, reverseLayout);
}
private int[] mMeasuredDimension = new int[2];
@Override
public void onMeasure(RecyclerView.Recycler recycler, RecyclerView.State state,
int widthSpec, int heightSpec) {
final int widthMode = View.MeasureSpec.getMode(widthSpec);
final int heightMode = View.MeasureSpec.getMode(heightSpec);
final int widthSize = View.MeasureSpec.getSize(widthSpec);
final int heightSize = View.MeasureSpec.getSize(heightSpec);
int width = 0;
int height = 0;
for (int i = 0; i < getItemCount(); i++) {
measureScrapChild(recycler, i,
View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
mMeasuredDimension);
if (getOrientation() == HORIZONTAL) {
width = width + mMeasuredDimension[0];
if (i == 0) {
height = mMeasuredDimension[1];
}
} else {
height = height + mMeasuredDimension[1];
if (i == 0) {
width = mMeasuredDimension[0];
}
}
}
// If child view is more than screen size, there is no need to make it wrap content. We can use original onMeasure() so we can scroll view.
if (height < heightSize && width < widthSize) {
switch (widthMode) {
case View.MeasureSpec.EXACTLY:
width = widthSize;
case View.MeasureSpec.AT_MOST:
case View.MeasureSpec.UNSPECIFIED:
}
switch (heightMode) {
case View.MeasureSpec.EXACTLY:
height = heightSize;
case View.MeasureSpec.AT_MOST:
case View.MeasureSpec.UNSPECIFIED:
}
setMeasuredDimension(width, height);
} else {
super.onMeasure(recycler, state, widthSpec, heightSpec);
}
}
private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
int heightSpec, int[] measuredDimension) {
View view = recycler.getViewForPosition(position);
// For adding Item Decor Insets to view
super.measureChildWithMargins(view, 0, 0);
if (view != null) {
RecyclerView.LayoutParams p = (RecyclerView.LayoutParams) view.getLayoutParams();
int childWidthSpec = ViewGroup.getChildMeasureSpec(widthSpec,
getPaddingLeft() + getPaddingRight() + getDecoratedLeft(view) + getDecoratedRight(view), p.width);
int childHeightSpec = ViewGroup.getChildMeasureSpec(heightSpec,
getPaddingTop() + getPaddingBottom() + getPaddingBottom() + getDecoratedBottom(view) , p.height);
view.measure(childWidthSpec, childHeightSpec);
// Get decorated measurements
measuredDimension[0] = getDecoratedMeasuredWidth(view) + p.leftMargin + p.rightMargin;
measuredDimension[1] = getDecoratedMeasuredHeight(view) + p.bottomMargin + p.topMargin;
recycler.recycleView(view);
}
}
}

This the most recent way to do this, the above answer is outdated:

After finding this page, along with several seemingly invasive solutions, I read through the hotfix option at https://support.microsoft.com/en-us/help/3002339/unexpected-dialog-box-appears-when-you-open-projects-in-visual-studio as suggested here.
Please avoid doing anything too drastic, and note the section of that page marked "Workaround" as shown below:
Workaround
To work around this issue, click OK when the dialog box appears after you either create a new project or open an existing Web Site Project or Windows Azure project. After you do this, the project works as expected.
In other words, click OK on the dialog box one time, and the message is gone forever. The project will work just fine.

So far, nobody has answered the actual question.
Someone can figure what is happening ?
The problem here is that while the value of your $JAVA_HOME
is correct, you defined it in the wrong place.
~/.bash_profile
file. Thus, when you enter echo $JAVA_HOME
, it will return the value that has been set there.~/.bash_profile
… why should it? So to IntelliJ, this variable is not set.There are two possible solutions to this:
"/Applications/IntelliJ IDEA.app/Contents/MacOS/idea"
. The idea
process will inherit any environment variables of Bash that have been export
ed. (Since you did export JAVA_HOME=…
, it works!), or, the sophisticated way:Set global environment variables that apply to all programs, not only Bash sessions. This is more complicated than you might think, and is explained here and here, for example. What you should do is run
/bin/launchctl setenv JAVA_HOME $(/usr/libexec/java_home)
However, this gets reset after a reboot. To make sure this gets run on every boot, execute
cat << EOF > ~/Library/LaunchAgents/setenv.JAVA_HOME.plist
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN"

Note that this also affects the Terminal process, so there is no need to put anything in your ~/.bash_profile
.
Just for the sake of completeness you can just take the wanted data type and add brackets with the number of elements like so:
x <- character(10)
Both these will give you the first child node:
console.log(parentElement.firstChild); // or
console.log(parentElement.childNodes[0]);
If you need the first child that is an element node then use:
console.log(parentElement.children[0]);
Edit
Ah, I see your problem now; parentElement
is an array.
If you know that getElementsByClassName will only return one result, which it seems you do, you should use [0]
to dearray (yes, I made that word up) the element:
var parentElement = document.getElementsByClassName("uniqueClassName")[0];
You can use method shown here and replace isNull
with isnan
:
from pyspark.sql.functions import isnan, when, count, col
df.select([count(when(isnan(c), c)).alias(c) for c in df.columns]).show()
+-------+----------+---+
|session|timestamp1|id2|
+-------+----------+---+
| 0| 0| 3|
+-------+----------+---+
or
df.select([count(when(isnan(c) | col(c).isNull(), c)).alias(c) for c in df.columns]).show()
+-------+----------+---+
|session|timestamp1|id2|
+-------+----------+---+
| 0| 0| 5|

I just came across a similar situation and was surprised at the rounding issues of 'very large numbers' presented within SSMS v17.9.1 / SQL 2017.
I am not suggesting I have a solution, however I have observed that FORMAT presents a number which appears correct. I can not imply this reduces further rounding issues or is useful within a complicated mathematical function.
T SQL Code supplied which should clearly demonstrate my observations while enabling others to test their code and ideas should the need arise.

If you are using debug configuration for maven, use the command
clean install
And skip all the tests.
var elems = document.querySelectorAll(".widget.hover");
[].forEach.call(elems, function(el) {
el.classList.remove("hover");
});
You can patch .classList
into IE9. Otherwise, you'll need to modify the .className
.
var elems = document.querySelectorAll(".widget.hover");
[].forEach.call(elems, function(el) {
el.className = el.className.replace(/\bhover\b/, "");
});
The .forEach()
also needs a patch for IE8, but that's pretty common anyway.
The files need to be in a JPEG or PNG format of 24 bits, in a 2:1 ratio if it is a portrait and a 16:9 ratio for landscapes. Be careful that if you go for different sizes: the maximum size should not be more than twice bigger than the minimum size.
Just throwing this out there...Can't you just do:
Collections.sort(myarrayList);
It's been awhile though...
You could always listen to the window resize event. If, on that event, the window went from being taller than it is wide to wider than it is tall (or vice versa), you can be pretty sure the phone orientation was just changed.
alias
is used to replace the location part path (LPP) in the request path, while the root
is used to be prepended to the request path.
They are two ways to map the request path to the final file path.
alias
could only be used in location block, and it will override the outside root
.
alias
and root
cannot be used in location block together.
I ran into this problem recently and solved it a different way. If you are running MySQL version 5.6.20 there is a known bug in the system. See MySQL docs
Important Due to Bug #69477, redo log writes for large, externally stored BLOB fields could overwrite the most recent checkpoint. To address this bug, a patch introduced in MySQL 5.6.20 limits the size of redo log BLOB writes to 10% of the redo log file size. As a result of this limit, innodb_log_file_size should be set to a value greater than 10 times the largest BLOB data size found in the rows of your tables plus the length of other variable length fields (VARCHAR, VARBINARY, and TEXT type fields).
In my situation the offending blob table was around 16MB. Thus, the way I solved it was by adding a line to my.cnf that ensured I had at least 10x that amount and then some:
innodb_log_file_size = 256M
While the answer given by Paul H shows the essential part, it is not a complete example. On the other hand the matplotlib example seems rather complicated and does not show how to use days.
So for everyone in need here is a full working example:
from datetime import datetime
import matplotlib.pyplot as plt
from matplotlib.dates import DateFormatter
myDates = [datetime(2012,1,i+3) for i in range(10)]
myValues = [5,6,4,3,7,8,1,2,5,4]
fig, ax = plt.subplots()
ax.plot(myDates,myValues)
myFmt = DateFormatter("%d")
ax.xaxis.set_major_formatter(myFmt)
## Rotate date labels automatically
fig.autofmt_xdate()
plt.show()
To find all files modified in the last 24 hours use the one below. The -1 here means changed 1 day or less ago.

This happened to me when I was trying to push the develop branch (I am using git flow). Someone had push updates to master. to fix it I did:
git co master
git pull
Which fetched those changes. Then,
git co develop
git pull
Which didn't do anything. I think the develop branch already pushed despite the error message. Everything is up to date now and no errors.
I stumbled over this as chocolatey sets M2_HOME
. I wanted to locate settings.xml
.
The current way for settings.xml
is to go to %USERPROFILE%
. There, a directory .m2
is contained, where one finds settings.xml
.
Never use M2_HOME
. It is unsupported since Apache Maven 3.5.0.
Details:
Based on problems in using
M2_HOME
related to different Maven versions installed and to simplify things, the usage ofM2_HOME
has been removed and is not supported any more MNG-5823, MNG-5836, MNG-5607.Important change for windows users: The usage of
%HOME%
has been replaced with%USERPROFILE%
MNG-6001

For me, I had //= require jquery
after //= require bootstrap
. Once I moved jquery before bootstrap, everything worked.
Random r = new Random();
int i1 = r.nextInt(80 - 65) + 65;
This gives a random integer between 65 (inclusive) and 80 (exclusive), one of 65,66,...,78,79
.
From looking at the source code, it seems like the pg_stat_database query gives you the number of connections to the current database for all users. On the other hand, the pg_stat_activity query gives the number of connections to the current database for the querying user only.
Ok, at that time got it done with the help of a friend and the code looks like this.
Sub Saving()
Dim part1 As String
Dim part2 As String
part1 = Range("C5").Value
part2 = Range("C8").Value
ActiveWorkbook.SaveAs Filename:= _
"C:\-docs\cmat\Desktop\pieteikumi\" & part1 & " " & part2 & ".xlsm", FileFormat:= _
xlOpenXMLWorkbookMacroEnabled, CreateBackup:=False
End Sub
How do I edit this part (FileFormat:= _ xlOpenXMLWorkbookMacroEnabled) for it to save as Excel 97-2013 Workbook, have tried several variations with no success. Thankyou
Seems, that I found the solution, but my idea is flawed. By doing this FileFormat:= _ xlOpenXMLWorkbook, it drops out a popup saying, the you cannot save this workbook as a file without Macro enabled. So, is this impossible?
You can use any of the following way based on Service Name
or SID
whatever you have.
With SID:
import cx_Oracle
dsn_tns = cx_Oracle.makedsn('server', 'port', 'sid')
conn = cx_Oracle.connect(user='username', password='password', dsn=dsn_tns)
c = conn.cursor()
c.execute('select count(*) from TABLE_NAME')
for row in c:
print(row)
conn.close()
OR
With Service Name:
import cx_Oracle
dsn_tns = cx_Oracle.makedsn('server', 'port', service_name='service_name')
conn = cx_Oracle.connect(user='username', password='password', dsn=dsn_tns)
c = conn.cursor()
c.execute('select count(*) from TABLE_NAME')
for row in c:
print(row)
conn.close()

Setting 'checked' or null instead of true or false respectively will do the work.
// checkbox selection
var $chk=$(':checkbox');
$chk.prop('checked',$chk.is(':checked') ? null:'checked');
If your error event handler takes the three arguments (xmlhttprequest, textstatus, and message) when a timeout happens, the status arg will be 'timeout'.
Per the jQuery documentation:
Possible values for the second argument (besides null) are "timeout", "error", "notmodified" and "parsererror".
You can handle your error accordingly then.
I created this fiddle that demonstrates this.
$.ajax({
url: "/ajax_json_echo/",
type: "GET",
dataType: "json",
timeout: 1000,
success: function(response) { alert(response); },
error: function(xmlhttprequest, textstatus, message) {
if(textstatus==="timeout") {
alert("got timeout");
} else {
alert(textstatus);
}
}
});?
With jsFiddle, you can test ajax calls -- it will wait 2 seconds before responding. I put the timeout setting at 1 second, so it should error out and pass back a textstatus of 'timeout' to the error handler.
Hope this helps!
erickson is almost right: since you want to match on counts of duplicates, you want a Bag. In Java, this looks something like:
(new HashBag(collection1)).equals(new HashBag(collection2))
I'm sure C# has a built-in Set implementation. I would use that first; if performance is a problem, you could always use a different Set implementation, but use the same Set interface.
The accepted answer worked for me using a CollapsingToolbarLayout. It's important to note though, that setSytstemUiVisibility()
overrides any previous calls to that function. So if you're using that function somewhere else for the same view, you need to include the View.SYSTEM_UI_FLAG_LAYOUT_STABLE
and View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
flags, or they will be overridden with the new call.
This was the case for me, and once I added the two flags to the other place I was making a call to setSystemUiVisibility()
, the accepted answer worked perfectly.
I've used something else (I think better...) and want to share it:
I created a VIEW that has a "group" clause
CREATE VIEW vCountries AS SELECT * PROVINCES GROUP BY country_code
SELECT * FROM client INNER JOIN vCountries on client_province = province_id
I want to say yet, that I think that we need to do this solution BECAUSE WE DID SOMETHING WRONG IN THE ANALYSIS... at least in my case... but sometimes it's cheaper to do this that to redesign everything...
I hope it helps!
Before MySQL 5.6 Full-Text Search is supported only with MyISAM Engine.
Therefore either change the engine for your table to MyISAM
CREATE TABLE gamemech_chat (
id bigint(20) unsigned NOT NULL auto_increment,
from_userid varchar(50) NOT NULL default '0',
to_userid varchar(50) NOT NULL default '0',
text text NOT NULL,
systemtext text NOT NULL,
timestamp datetime NOT NULL default '0000-00-00 00:00:00',
chatroom bigint(20) NOT NULL default '0',
PRIMARY KEY (id),
KEY from_userid (from_userid),
FULLTEXT KEY from_userid_2 (from_userid),
KEY chatroom (chatroom),
KEY timestamp (timestamp)
) ENGINE=MyISAM;
Here is SQLFiddle demo
or upgrade to 5.6 and use InnoDB Full-Text Search.
I had a similar problem recently, and needed to change the permissions of my vendor folder
By running following commands :
php artisan cache:clear
chmod -R 777 storage vendor
composer dump-autoload
I need to give all the permissions required to open and write vendor files to solve this issue
This works too and also demonstrates how to change the legend title:
ggplot(df, aes(x, y, colour=g)) +
geom_line(stat="identity") +
theme(legend.position="bottom") +
scale_color_discrete(name="")
Here is a workaround using a flag:
//outside your event or method, but inside your class
private bool IsExecuted = false;
private async Task MethodA()
{
//Do Stuff Here
IsExecuted = true;
}
.
.
.
//Inside your event or method
{
await MethodA();
while (!isExecuted) Thread.Sleep(200); // <-------
await MethodB();
}
Represent it as a text entity (ASCII 39):
<input type='text' id='abc' value='hel'lo'>
Either use the

Had this issue on Python 2.7.9, solved by updating to Python 2.7.10 (unreleased when this question was asked and answered).
I used the command netstat -ano | grep "portnumber"
in order to list out the port number/PID for that process.
Then, you can use taskkill -f //pid 111111
to kill the process, last value being the pid you find from the first command.
One problem I run into at times is node respawning even after killing the process, so I have to use the good old task manager to manually kill the node process.
What worked for me now is:
CSS:
.right {
text-align: right;
margin-right: 1em;
}
.left {
text-align: left;
margin-left: 1em;
}
HTML:
<table width="100%">
<tbody>
<tr>
<td class="left">
<input id="abort" type="submit" name="abort" value="Back">
<input id="save" type="submit" name="save" value="Save">
</td>
<td class="right">
<input id="delegate" type="submit" name="delegate" value="Delegate">
<input id="unassign" type="submit" name="unassign" value="Unassign">
<input id="complete" type="submit" name="complete" value="Complete">
</td>
</tr>

See the following fiddle:
class Node:
rChild,lChild,data = None,None,None
This is wrong - it makes your variables class variables - that is, every instance of Node uses the same values (changing rChild of any node changes it for all nodes!). This is clearly not what you want; try
class Node:
def __init__(self, key):
self.rChild = None
self.lChild = None
self.data = key
now each node has its own set of variables. The same applies to your definition of Tree,
class Tree:
root,size = None,0 # <- lose this line!
def __init__(self):
self.root = None
self.size = 0
Further, each class should be a "new-style" class derived from the "object" class and should chain back to object.__init__():
class Node(object):
def __init__(self, data, rChild=None, lChild=None):
super(Node,self).__init__()
self.data = data
self.rChild = rChild
self.lChild = lChild
class Tree(object):
def __init__(self):
super(Tree,self).__init__()
self.root = None
self.size = 0
Also, main() is indented too far - as shown, it is a method of Tree which is uncallable because it does not accept a self argument.
Also, you are modifying the object's data directly (t.root = Node(4)
) which kind of destroys encapsulation (the whole point of having classes in the first place); you should be doing something more like
def main():
t = Tree()
t.add(4) # <- let the tree create a data Node and insert it
t.add(5)
