@Jon's answer is the best solution when you want full detail (all the messages and the stack trace) and the recommended one.
However, there might be cases when you just want the inner messages, and for these cases I use the following extension method:
public static class ExceptionExtensions
{
public static string GetFullMessage(this Exception ex)
{
return ex.InnerException == null
? ex.Message
: ex.Message + " --> " + ex.InnerException.GetFullMessage();
}
}
I often use this method when I have different listeners for tracing and logging and want to have different views on them. That way I can have one listener which sends the whole error with stack trace by email to the dev team for debugging using the .ToString()
method and one that writes a log on file with the history of all the errors that happened each day without the stack trace with the .GetFullMessage()
method.
What Mark Rushakoff said is true, but if you iterate in the opposite direction, it is possible to remove elements from the list in the for-loop as well. E.g.,
x = [1,2,3,0,0,1]
for i in range(len(x)-1, -1, -1):
if x[i] == 0:
x.pop(i)
It's like a tall building that falls from top to bottom: even if it is in the middle of collapse, you still can "enter" into it and visit yet-to-be-collapsed floors.
Be aware that if your string number contains more than 15 significant digits float(s)
will round it.In those cases it is better to use Decimal
Here is an explanation and some code samples: https://docs.python.org/3/library/sys.html#sys.float_info
This is a broad question and there are multiple ways you can achieve this. In my experience, I've seen a lot of single page applications having an entry point file such as index.js
. This file would be responsible for 'bootstrapping' the application and will be your entry point for webpack.
index.js
import React from 'react';
import ReactDOM from 'react-dom';
import Application from './components/Application';
const root = document.getElementById('someElementIdHere');
ReactDOM.render(
<Application />,
root,
);
Your <Application />
component would contain the next pieces of your app. You've stated you want different pages and that leads me to believe you're using some sort of routing. That could be included into this component along with any libraries that need to be invoked on application start. react-router
, redux
, redux-saga
, react-devtools
come to mind. This way, you'll only need to add a single entry point into your webpack configuration and everything will trickle down in a sense.
When you've setup a router, you'll have options to set a component to a specific matched route. If you had a URL of /about
, you should create the route in whatever routing package you're using and create a component of About.js
with whatever information you need.
This is totally OK.
m.group(0)
) always captures the whole area that is covered by your regular expression. In this case, it's the whole string.(.*)(\\d+)
(the first part of your regex) covers the ...QT300
int the first group and the 0
in the second.(.*)
to (.*?)

Just use setTimeOut
with recursion:
waitUntilElementIsPresent(callback: () => void): void {
if (!this.methodToCheckIfElementIsPresent()) {
setTimeout(() => this.waitUntilElementIsPresent(callback), 500);
return;
}
callback();
}
Usage:
this.waitUntilElementIsPresent(() => console.log('Element is present!'));
You can limit amount of attempts, so an error will be thrown when the element is not present after the limit:
waitUntilElementIsPresent(callback: () => void, attempt: number = 0): void {
const maxAttempts = 10;
if (!this.methodToCheckIfElementIsPresent()) {
attempt++;
setTimeout(() => this.waitUntilElementIsPresent(callback, attempt), 500);
return;
} else if (attempt >= maxAttempts) {
return;
}
callback();
}
Just add:
import os
in the beginning, before:
from settings import PROJECT_ROOT
This will import the python's module os, which apparently is used later in the code of your module without being imported.
You can use the package sklearn and its associated preprocessing utilities to normalize the data.
import pandas as pd
from sklearn import preprocessing
x = df.values #returns a numpy array
min_max_scaler = preprocessing.MinMaxScaler()
x_scaled = min_max_scaler.fit_transform(x)
df = pd.DataFrame(x_scaled)
For more information look at the scikit-learn documentation on preprocessing data: scaling features to a range.
You can use
LEFT(column, length)
or
SUBSTRING(column, start index, length)
Ecma script 5 (ES5) which all browser support and precompiled. ES6/ES2015 and ES/2016 came this year with lots of changes so to pop up these changes there is something in between which should take cares about so TypeScript.
• TypeScript is Types -> Means we have to define datatype of each property and methods. If you know C# then Typescript is easy to understand.
• Big advantage of TypeScript is we identify Type related issues early before going to production. This allows unit tests to fail if there is any type mismatch.
If it is a valid change.
you can change the property.
Tools --> Options --> Designers --> Table and Database designers --> Uncheck --> Prevent saving changes that required table re-creation.
Now you can easily change the column name without recreating the table or losing u r records.
Also register your created service in the Manifest and uses-permission as
<application ...>
<service android:name=".MyBroadcastReceiver">
<intent-filter>
<action android:name="com.example.MyBroadcastReciver"/>
</intent-filter>
</service>
</application>
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>
and then in braod cast Reciever call your service
public class MyBroadcastReceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
Intent myIntent = new Intent(context, MyService.class);
context.startService(myIntent);
}
}
dynamic_cast uses RTTI. It can slow down your application, you can use modification of the visitor design pattern to achieve downcasting without RTTI http://arturx64.github.io/programming-world/2016/02/06/lazy-visitor.html
Be carefull NOT IN
is not an alias for <> ANY
, but for <> ALL
!

SELECT c FROM t1 LEFT JOIN t2 USING (c) WHERE t2.c IS NULL
cant' be replaced by
SELECT c FROM t1 WHERE c NOT IN (SELECT c FROM t2)
You must use
SELECT c FROM t1 WHERE c <> ANY (SELECT c FROM t2)
BUILD_ID
used to provide this information but they changed it to provide the Build Number since Jenkins 1.597. Refer this for more information.
You can achieve this using the Build Time Stamp plugin as pointed out in the other answers.
However, if you are not allowed or not willing to use a plugin, follow the below method:
def BUILD_TIMESTAMP = null
withCredentials([usernamePassword(credentialsId: 'JenkinsCredentials', passwordVariable: 'JENKINS_PASSWORD', usernameVariable: 'JENKINS_USERNAME')]) {
sh(script: "curl https://${JENKINS_USERNAME}:${JENKINS_PASSWORD}@<JENKINS_URL>/job/<JOB_NAME>/lastBuild/buildTimestamp", returnStdout: true).trim();
}
println BUILD_TIMESTAMP
This might seem a bit of overkill but manages to get the job done.
The credentials for accessing your Jenkins should be added and the id needs to be passed in the withCredentials
statement, in place of 'JenkinsCredentials'
. Feel free to omit that step if your Jenkins doesn't use authentication.
There isn't one built in, but it's simple to roll your own, as demonstrated here:
import operator
def prod(factors):
return reduce(operator.mul, factors, 1)

First of all: Yes you can mix jQuery with common JS :)
Best way to build up an intervall call of a function is to use setTimeout methode:
For example, if you have a function called test() and want to repeat it all 5 seconds, you could build it up like this:
function test(){
console.log('test called');
setTimeout(test, 5000);
}
Finally you have to trigger the function once:
$(document).ready(function(){
test();
});
This document ready function is called automatically, after all html is loaded.
On Mac OS X installing nginx with brew makes the default directory:
/usr/local/var/www
So:
root html
means
root /usr/local/var/www/html
There is no html directory so it would have to be created manually.
It just doesn't support pointers, end of story :-(.
I would like to add that, while I'm brand new and coming from a C background, from what I'm reading about the event loop and stack, you should keep whichever object as close to its caller as possible. As I'm brand new, I could have this wrong.
A lot of answers here suggest to make it global, but again if I'm reading correctly, that could possibly increase the stack hops and in a way, possibly fragment your event loop needlessly (depending on what the called object is currently doing) .
Also, any example given that mimics pointers, is just 1 in many ways to do the same thing, which will not be a pointer.
Yate (https://github.com/pasaran/yate) is specifically designed after XSLT, features JPath (a natural XPath equivalent for JS), compiles to JavaScript and has quite a history of production use. It’s practically undocumented, but reading through samples and tests should be enough.
If you are using GCC, you can use the GNU extension asprintf function.
char* str;
asprintf (&str, "%i", 12313);
free(str);
Most Git repositories use master
as the main (and default) branch - if you initialize a new Git repo via git init
, it will have master
checked out by default.
However, if you clone a repository, the default branch you have is whatever the remote's HEAD
points to (HEAD
is actually a symbolic ref that points to a branch name). So if the repository you cloned had a HEAD
pointed to, say, foo
, then your clone will just have a foo
branch.
The remote you cloned from might still have a master
branch (you could check with git ls-remote origin master
), but you wouldn't have created a local version of that branch by default, because git clone
only checks out the remote's HEAD
.
you can use instead of click :
$('#whatever').on('touchstart click', function(){ /* do something... */ });
At any stage of maven build life cycle, all the previous goals are performed.
Ex: mvn install will invoke mvn validate, mvn compile, mvn test, mvn package etc.
var reader = cmd.ExecuteReader();
var columns = new List<string>();
for(int i=0;i<reader.FieldCount;i++)
{
columns.Add(reader.GetName(i));
}
or
var columns = Enumerable.Range(0, reader.FieldCount).Select(reader.GetName).ToList();
Your syntax is incorrect.
card_value = $(array[i]).val();
or card_value = array[i].value;
array[i] is not a jQuery object (for some reason).
Checking your browser's console can be helpful for things like this.

If you use windows server, you can change Environment Variable, restart server to apply new Environment Value and start Elastic Service. More detail in Install Elastic in Windows Server
We can read website html content as below :
from urllib.request import urlopen
response = urlopen('http://google.com/')
html = response.read()
print(html)
Do you actually have the single quotes in your command? I don't think they are necessary. Plus, I think you also need --no-auth-cache
and --non-interactive
Here is what I use (no single quotes)
--non-interactive --no-auth-cache --username XXXX --password YYYY
See the Client Credentials Caching documentation in the svnbook for more information.
I had the same problem. I closed terminal and restarted node. This worked for me.
Check out javapassion, they have a number of courses that encompass web programming, and were free (until circumstances conspired to make the website need to support itself).
Even with the nominal fee, you get a lot for an entire year. It's a bargain compared to the amount of time you'll be investing.
The other options are to look to Oracle's online tutorials, they lack the glitz of Codeacademy, but are surprisingly good. I haven't read the one on web programming, that might be embedded in the Java EE tutorial(s), which is not tuned for a new beginner to Java.
for var index = self.indexOfObject(object); index != NSNotFound; index = self.indexOfObject(object)
is for loop in C-style and has been removed
Change your code to something like this to remove all similar object if it have looped:
let indexes = arrContacts.enumerated().filter { $0.element == contacts[indexPath.row] }.map{ $0.offset }
for index in indexes.reversed() {
arrContacts.remove(at: index)
}
You also have the Trim, TrimEnd and TrimStart methods of the System.String class. The trim method will strip whitespace (with a couple of Unicode quirks) from the leading and trailing portion of the string while allowing you to optionally specify the characters to remove.
#Note there are spaces at the beginning and end
Write-Host " ! This is a test string !%^ "
! This is a test string !%^
#Strips standard whitespace
Write-Host " ! This is a test string !%^ ".Trim()
! This is a test string !%^
#Strips the characters I specified
Write-Host " ! This is a test string !%^ ".Trim('!',' ')
This is a test string !%^
#Now removing ^ as well
Write-Host " ! This is a test string !%^ ".Trim('!',' ','^')
This is a test string !%
Write-Host " ! This is a test string !%^ ".Trim('!',' ','^','%')
This is a test string
#Powershell even casts strings to character arrays for you
Write-Host " ! This is a test string !%^ ".Trim('! ^%')
This is a test string
TrimStart and TrimEnd work the same way just only trimming the start or end of the string.
I tried (with minor changes as suggested) the code from Andrew Cooke's answer. (I am running python 2.7).
The code:
#!/usr/bin/env python
class Celsius:
def __get__(self, instance, owner): return 9 * (instance.fahrenheit + 32) / 5.0
def __set__(self, instance, value): instance.fahrenheit = 32 + 5 * value / 9.0
class Temperature:
def __init__(self, initial_f): self.fahrenheit = initial_f
celsius = Celsius()
if __name__ == "__main__":
t = Temperature(212)
print(t.celsius)
t.celsius = 0
print(t.fahrenheit)
The result:
C:\Users\gkuhn\Desktop>python test2.py
<__main__.Celsius instance at 0x02E95A80>
212
With Python prior to 3, make sure you subclass from object which will make the descriptor work correctly as the get magic does not work for old style classes.
I guess it's best way to set attributes at once for any element in this class.
function SetAtt(elements, attributes) {
for (var element = 0; element < elements.length; element++) {
for (var attribute = 0; attribute < attributes.length; attribute += 2) {
elements[element].setAttribute(attributes[attribute], attributes[attribute + 1]);
}
}
}
var Class = document.getElementsByClassName("ClassName"); // class array list
var Data = ['att1', 'val1', 'att2', 'val2', 'att3', 'val3']; //attributes array list
SetAtt(Class, Data);
you can add custom clear button and control the size and every thing using this:
UIButton *clearButton = [UIButton buttonWithType:UIButtonTypeCustom];
[clearButton setImage:img forState:UIControlStateNormal];
[clearButton setFrame:frame];
[clearButton addTarget:self action:@selector(clearTextField:) forControlEvents:UIControlEventTouchUpInside];
textField.rightViewMode = UITextFieldViewModeAlways; //can be changed to UITextFieldViewModeNever, UITextFieldViewModeWhileEditing, UITextFieldViewModeUnlessEditing
[textField setRightView:clearButton];

Here's an updated answer for the latest Bootstrap 4.0.0. This version has classes that will help you create a sticky or fixed sidebar without the extra CSS....
Use sticky-top
:
<div class="container">
<div class="row py-3">
<div class="col-3 order-2" id="sticky-sidebar">
<div class="sticky-top">
...
</div>
</div>
<div class="col" id="main">
<h1>Main Area</h1>
...
</div>
</div>
</div>
Demo: https://codeply.com/go/O9GMYBer4l
or, use position-fixed
:
<div class="container-fluid">
<div class="row">
<div class="col-3 px-1 bg-dark position-fixed" id="sticky-sidebar">
...
</div>
<div class="col offset-3" id="main">
<h1>Main Area</h1>
...
</div>
</div>
</div>
Demo: https://codeply.com/p/0Co95QlZsH

The fastest code for counting files with ANY attributes in folder %FOLDER%
and its subfolders is the following. The code is for script in a command script (batch) file.
@for /f %%a in ('2^>nul dir "%FOLDER%" /a-d/b/-o/-p/s^|find /v /c ""') do set n=%%a
@echo Total files: %n%.
This useful query also works if you are using Azure SQL / Synapse Anlaytics

FROM sys.sql_modules m
INNER JOIN sys.objects o
ON m.object_id=o.object_id
WHERE m.definition Like '%Table_Name%'
You can also use the Termial view to ssh/telnet to your local machine. Doesn't have that funny input box for commands.
For question #1, let's break it into two parts. First, increment any document that has "items.item_name" equal to "my_item_two". For this you'll have to use the positional "$" operator. Something like:
db.bar.update( {user_id : 123456 , "items.item_name" : "my_item_two" } ,
{$inc : {"items.$.price" : 1} } ,
false ,
true);
Note that this will only increment the first matched subdocument in any array (so if you have another document in the array with "item_name" equal to "my_item_two", it won't get incremented). But this might be what you want.
The second part is trickier. We can push a new item to an array without a "my_item_two" as follows:
db.bar.update( {user_id : 123456, "items.item_name" : {$ne : "my_item_two" }} ,
{$addToSet : {"items" : {'item_name' : "my_item_two" , 'price' : 1 }} } ,
false ,
true);
For your question #2, the answer is easier. To increment the total and the price of item_three in any document that contains "my_item_three," you can use the $inc operator on multiple fields at the same time. Something like:
db.bar.update( {"items.item_name" : {$ne : "my_item_three" }} ,
{$inc : {total : 1 , "items.$.price" : 1}} ,
false ,
true);
The simpliest way I've found to get the current UTC time in milliseconds is:
# timeutil.py
import datetime
def get_epochtime_ms():
return round(datetime.datetime.utcnow().timestamp() * 1000)
# sample.py
import timeutil
timeutil.get_epochtime_ms()
Imho, writing
python /path/to/script.py
Is quite wrong, especially in these days. Which python? python2.6? 2.7? 3.0? 3.1? Most of times you need to specify the python version in shebang tag of python file. I encourage to use
#!/usr/bin/env python2 #or python2.6 or python3 or even python3.1for compatibility.
In such case, is much better to have the script executable and invoke it directly:
#!/bin/bash /path/to/script.py
This way the version of python you need is only written in one file. Most of system these days are having python2 and python3 in the meantime, and it happens that the symlink python points to python3, while most people expect it pointing to python2.
If you associate default functions for (sub)parsers, as is mentioned under add_subparsers
, you can simply add it as the default action:
parser = argparse.ArgumentParser()
parser.set_defaults(func=lambda x: parser.print_usage())
args = parser.parse_args()
args.func(args)
Add the try-except if you raise exceptions due to missing positional arguments.
This is what I found:
Demo: http://tympanus.net/Tutorials/ItemBlur/
and Tutorial: http://tympanus.net/codrops/2011/12/14/item-blur-effect-with-css3-and-jquery/
The statement:
(my $newstring = $oldstring) =~ s/foo/bar/g;
Which is equivalent to:
my $newstring = $oldstring;
$newstring =~ s/foo/bar/g;
Alternatively, as of Perl 5.13.2 you can use /r
to do a non destructive substitution:
use 5.013;
#...
my $newstring = $oldstring =~ s/foo/bar/gr;
Because if a factor is greater than the square root of n, the other factor that would multiply with it to equal n is necessarily less than the square root of n.
<a href="javascript:void(0)" class="aaf" id="users_id">add as a friend</a>
on jquery
$('.aaf').on("click",function(){
var usersid = $(this).attr("id");
//post code
})
//other method is to use the data attribute
<a href="javascript:void(0)" class="aaf" data-id="102" data-username="sample_username">add as a friend</a>
on jquery
$('.aaf').on("click",function(){
var usersid = $(this).data("id");
var username = $(this).data("username");
})
Your example works because you are passing the address of your variable to a function that manipulates its value with the dereference operator.
While C does not support reference data types, you can still simulate passing-by-reference by explicitly passing pointer values, as in your example.
The C++ reference data type is less powerful but considered safer than the pointer type inherited from C. This would be your example, adapted to use C++ references:
void f(int &j) {
j++;
}
int main() {
int i = 20;
f(i);
printf("i = %d\n", i);
return 0;
}
The lubridate package is amazing for this kind of thing:

Tieme put a lot of effort into his excellent answer, but I think the core of the OP's question is how these technologies relate to PHP rather than how each technology works.
PHP is the most used language in web development besides the obvious client side HTML, CSS, and Javascript. Yet PHP has 2 major issues when it comes to real-time applications:
libphp5.so
on Linux, php5ts.dll
on Windows, etc) as if it still a CGI processing a GET/POST request. It still executes code as if it just has to build a "page" and then end its life cycle. As a result, it has very little support for multi-thread or event-driven programming (within PHP userspace), making it currently unpractical for real-time, multi-user applications.Note that PHP does have extensions to provide event loops (such as libevent
) and threads (such as pthreads
) in PHP userspace, but very, very, few of the applications use these.
PHP 7 will be a great step to fix these issues as well, and seems very promising as a platform for real-time applications.
Try this:
String output = response.getEntity(String.class);
EDIT
Thanks to @Martin Spamer to mention that it will work for Jersey 1.x jars only. For Jersey 2.x use
String output = response.readEntity(String.class);
I think this article explains well:

Resurrecting this to post the DISTINCT FROM
option, which has been around since Postgres 8. The approach is similar to Brad Dre's answer. In your case, your select would be something like
SELECT *

# docker rm $(docker ps -q -f 'status=exited')
After execution of the above commands, restart docker by,

You can try to use this function if you need to round down to a specific number of decimal places
function roundDown(number, decimals) {
decimals = decimals || 0;
return ( Math.floor( number * Math.pow(10, decimals) ) / Math.pow(10, decimals) );
}
examples
alert(roundDown(999.999999)); // 999
alert(roundDown(999.999999, 3)); // 999.999
alert(roundDown(999.999999, -1)); // 990
Simple way
Create a new java class
public class ActivityName extends FragmentActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState == null){
getSupportFragmentManager().beginTransaction()
.add(android.R.id.content, new Fragment_name_which_you_wantto_open()).commit();}
}
}
in your activity where u want to call fragment
Intent i = new Intent(Currentactivityname.this,ActivityName.class);
startActivity(i);
Another Method
Place frame layout in your activity where u want to open fragment
<FrameLayout
android:id="@+id/frameLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</FrameLayout>
Paste this code where u want to open fragment
Fragment mFragment = null;
mFragment = new Name_of_fragment_which_you_want_to_open();
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.frameLayout, mFragment).commit();
try it:
const cors = require('cors')
const corsOptions = {
origin: 'http://localhost:4200',
credentials: true,
}
app.use(cors(corsOptions));
To answer your question, you can explore the contents of the model's output by saving the model as a variable and clicking on it in the environment window. You can then click around to see what it contains and what is stored where.
Another way is to type yourmodelname$
and select the components of the model one by one to see what each contains. When you get to yourmodelname$coefficients
, you will see all of beta-, p, and t- values you desire.

Exception handling is included in free standing implementations.
The reason of this is that you possibly use gcc
to compile your code. If you compile with the option -###
you will notice it is missing the linker-option -lstdc++
when it invokes the linker process . Compiling with g++
will include that library, and thus the symbols defined in it.
Jawn is a very flexible JSON parser library in Scala. It also allows generation of custom ASTs; you just need to supply it with a small trait to map to the AST.
Worked great for a recent project that needed a little bit of JSON parsing.
I'm aware this is quite old but I just had the same problem with Visual Studio 2010 all patched up so others may still run into this.

Try disabling any anti-virus/resident shield and see if it fixes the problem. If so, add your project path to excluded directories in your AV config.
When you don't care about removing the Html Dom-Element, use *ngIf.
Otherwise, use this:
<div [style.visibility]="(numberOfUnreadAlerts == 0) ? 'hidden' : 'visible' ">
COUNTER: {{numberOfUnreadAlerts}}
</div>
$(':focus')[0]
will give you the actual element.
$(':focus')
will give you an array of elements, usually only one element is focused at a time so this is only better if you somehow have multiple elements focused.
Brian, This approach works great for non-Ajax requests, but as Lion_cl stated, if you have an error during an Ajax call, your Share/Error.aspx view (or your custom error page view) will be returned to the Ajax caller--the user will NOT be redirected to the error page.
If you need to order your code into namespaces, just use the keyword namespace
:
file1.php
namespace foo\bar;
In file2.php
$obj = new \foo\bar\myObj();
You can also use use
. If in file2 you put
use foo\bar as mypath;
you need to use mypath
instead of bar
anywhere in the file:
$obj = new mypath\myObj();
Using use foo\bar;
is equal to use foo\bar as bar;
.
for (var i = 0; i < 10; i = i + 2) {
// code here
}?
I was getting the error:
NameError: uninitialized constant
Then I noticed that I had accidentally created a plural model so I went back and renamed the model file to singular and also changed the class name in the model file to singular and that solved it.
The nature of arrays is that their length is immutable. You can't add or delete any of the array items.
You will have to create a new array that is one element shorter and copy the old items to the new array, excluding the element you want to delete.
So it is probably better to use a List instead of an array.
You must update the Windows PowerShell to minimum of version 4.0 for the script below to work.
[array]$SiteLinks = "http://mypage.global/Chemical/test.html"
"http://maypage2:9080/portal/site/hotpot/test.json"
foreach($url in $SiteLinks) {
try {
Write-host "Verifying $url" -ForegroundColor Yellow
$checkConnection = Invoke-WebRequest -Uri $url
if ($checkConnection.StatusCode -eq 200) {
Write-Host "Connection Verified!" -ForegroundColor Green
}
}
catch [System.Net.WebException] {
$exceptionMessage = $Error[0].Exception
if ($exceptionMessage -match "503") {
Write-Host "Server Unavaiable" -ForegroundColor Red
}
elseif ($exceptionMessage -match "404") {
Write-Host "Page Not found" -ForegroundColor Red
}
}
}
This might make a little more sense from a coding perspective (available with ant-contrib: http://ant-contrib.sourceforge.net/):
<target name="someTarget">
<if>
<available file="abc.txt"/>
<then>
...
</then>
<else>
...
</else>
</if>
</target>
VLookup
You can do it with a simple VLOOKUP formula. I've put the data in the same sheet, but you can also reference a different worksheet. For the price column just change the last value from 2 to 3, as you are referencing the third column of the matrix "A2:C4".
External Reference
To reference a cell of the same Workbook use the following pattern:
<Sheetname>!<Cell>
Example:
Table1!A1
To reference a cell of a different Workbook use this pattern:
[<Workbook_name>]<Sheetname>!<Cell>
Example:
[MyWorkbook]Table1!A1
Previous answers assume that the branch to be reset is the current branch (checked out). In comments, OP hap497 clarified that the branch is indeed checked out, but this is not explicitly required by the original question. Since there is at least one "duplicate" question, Reset branch completely to repository state, which does not assume that the branch is checked out, here's an alternative:
If branch "mybranch" is not currently checked out, to reset it to remote branch "myremote/mybranch"'s head, you can use this low-level command:
git update-ref refs/heads/mybranch myremote/mybranch
This method leaves the checked out branch as it is, and the working tree untouched. It simply moves mybranch's head to another commit, whatever is given as the second argument. This is especially helpful if multiple branches need to be updated to new remote heads.
Use caution when doing this, though, and use gitk
or a similar tool to double check source and destination. If you accidentally do this on the current branch (and git will not keep you from this), you may become confused, because the new branch content does not match the working tree, which did not change (to fix, update the branch again, to where it was before).

Bootstrap 3
Yes, it's possible. This "off-canvas" example should help to get you started.
https://codeply.com/p/esYgHWB2zJ
Basically you need to wrap the layout in an outer div, and use media queries to toggle the layout on smaller screens.
/* collapsed sidebar styles */
@media screen and (max-width: 767px) {
.row-offcanvas {
position: relative;
-webkit-transition: all 0.25s ease-out;
-moz-transition: all 0.25s ease-out;
transition: all 0.25s ease-out;
}
.row-offcanvas-right
.sidebar-offcanvas {
right: -41.6%;
}
.row-offcanvas-left
.sidebar-offcanvas {
left: -41.6%;
}
.row-offcanvas-right.active {
right: 41.6%;
}
.row-offcanvas-left.active {
left: 41.6%;
}
.sidebar-offcanvas {
position: absolute;
top: 0;
width: 41.6%;
}
#sidebar {
padding-top:0;
}
}
Also, there are several more Bootstrap sidebar examples here
Bootstrap 4
I'd suggest getting into one of the JS libraries out there. They ensure compatibility so you can get up and running really fast. jQuery and DOJO are both really great. To do what you're trying to do in jQuery, for example, it would go something like this:
<script type="text/javascript" language="JavaScript">
$.ajax({
url: "x.html",
context: document.body,
success: function(response) {
$("#yourDiv").html(response);
}
});
</script>
You need to make the object first, then use []
to set it.
var key = "happyCount";
var obj = {};
obj[key] = someValueArray;
myArray.push(obj);
UPDATE 2018:
If you're able to use ES6 and Babel, you can use this new feature:
{
[yourKeyVariable]: someValueArray,
}
I have tried all the above steps mentioned but nothing worked for me. Finally, restarting the computer worked for this issue :D
IDLE's console does not support ANSI escape sequences, or any other form of escapes for coloring your output.
You can learn how to talk to IDLE's console directly instead of just treating it like normal stdout and printing to it (which is how it does things like color-coding your syntax), but that's pretty complicated. The idle
documentation just tells you the basics of using IDLE itself, and its idlelib
library has no documentation (well, there is a single line of documentation—"(New in 2.3) Support library for the IDLE development environment."—if you know where to find it, but that isn't very helpful). So, you need to either read the source, or do a whole lot of trial and error, to even get started.
Alternatively, you can run your script from the command line instead of from IDLE, in which case you can use whatever escape sequences your terminal handles. Most modern terminals will handle at least basic 16/8-color ANSI. Many will handle 16/16, or the expanded xterm-256 color sequences, or even full 24-bit colors. (I believe gnome-terminal
is the default for Ubuntu, and in its default configuration it will handle xterm-256, but that's really a question for SuperUser or AskUbuntu.)
Learning to read the termcap
entries to know which codes to enter is complicated… but if you only care about a single console—or are willing to just assume "almost everything handles basic 16/8-color ANSI, and anything that doesn't, I don't care about", you can ignore that part and just hardcode them based on, e.g., this page.
Once you know what you want to emit, it's just a matter of putting the codes in the strings before printing them.
But there are libraries that can make this all easier for you. One really nice library, which comes built in with Python, is curses
. This lets you take over the terminal and do a full-screen GUI, with colors and spinning cursors and anything else you want. It is a little heavy-weight for simple uses, of course. Other libraries can be found by searching PyPI, as usual.
I whould choose swing just because it's "native" for java.
Plus, have a look at http://swingx.java.net/.
This can be done by using the java.net.URI class to construct a new instance using the parts from an existing one, this should ensure it conforms to URI syntax.
The query part will either be null or an existing string, so you can decide to append another parameter with & or start a new query.
public class StackOverflow26177749 {
public static URI appendUri(String uri, String appendQuery) throws URISyntaxException {
URI oldUri = new URI(uri);
String newQuery = oldUri.getQuery();
if (newQuery == null) {
newQuery = appendQuery;
} else {
newQuery += "&" + appendQuery;
}
return new URI(oldUri.getScheme(), oldUri.getAuthority(),
oldUri.getPath(), newQuery, oldUri.getFragment());
}
public static void main(String[] args) throws Exception {
System.out.println(appendUri("http://example.com", "name=John"));
System.out.println(appendUri("http://example.com#fragment", "name=John"));
System.out.println(appendUri("http://[email protected]", "name=John"));
System.out.println(appendUri("http://[email protected]#fragment", "name=John"));
}
}
Shorter alternative
public static URI appendUri(String uri, String appendQuery) throws URISyntaxException {
URI oldUri = new URI(uri);
return new URI(oldUri.getScheme(), oldUri.getAuthority(), oldUri.getPath(),
oldUri.getQuery() == null ? appendQuery : oldUri.getQuery() + "&" + appendQuery, oldUri.getFragment());
}
Output
http://example.com?name=John
http://example.com?name=John#fragment
http://[email protected]&name=John
http://[email protected]&name=John#fragment
In order to add the file to the email as an attachment, it will need to be stored on the server briefly. It's trivial, though, to place it in a tmp location then delete it after you're done with it.
As for emailing, Zend Mail has a very easy to use interface for dealing with email attachments. We run with the whole Zend Framework installed, but I'm pretty sure you could just install the Zend_Mail library without needing any other modules for dependencies.
With Zend_Mail, sending an email with an attachment is as simple as:
$mail = new Zend_Mail();
$mail->setSubject("My Email with Attachment");
$mail->addTo("[email protected]");
$mail->setBodyText("Look at the attachment");
$attachment = $mail->createAttachment(file_get_contents('/path/to/file'));
$mail->send();
If you're looking for a one-file-package to do the whole form/email/attachment thing, I haven't seen one. But the individual components are certainly available and easy to assemble. Trickiest thing of the whole bunch is the email attachment, which the above recommendation makes very simple.
This way you can remove all spaces from all character variables in your data frame. If you would prefer to choose only some of the variables, use mutate
or mutate_at
.
library(dplyr)
library(stringr)
remove_all_ws<- function(string){
return(gsub(" ", "", str_squish(string)))
}
df<-df %>% mutate_if(is.character, remove_all_ws)
May be this helps someone. The error I was getting was
SyntaxError: expected expression, got '<'
What I did clicked on view source in chrome and there I found this error
Notice: Undefined variable: string in D:\Projects\demo\ge.php on line 66
The issue was this snippet of code,
$string= ''; <---- this should be declared outside the loop
while($row = mysql_fetch_assoc($result))
{
$string .= '{ id:'.$row['menu_id'].', pId:'.$row['parent_id'].', name:"'.$row['menu_name'].'"},';
}
which fixed the problem.
You could use IsEmpty()
function like this:
...
Set rRng = Sheet1.Range("A10")
If IsEmpty(rRng.Value) Then ...
you could also use following:
If ActiveCell.Value = vbNullString Then ...
Your define following in router.js
$stateProvider.state('users', {
url: '/users',
controller: 'UsersCtrl',
params: {
obj: null
}
})
Your controller need add $stateParams.
function UserCtrl($stateParams) {
console.log($stateParams);
}
You can send an object by parameter as follows.
$state.go('users', {obj:yourObj});
If the author has a GitHub account, just click the author's username from anywhere in the commit history, and the commits you can see will be filtered down to those by that author:
You can also click the 'n commits' link below their name on the repo's "contributors" page:
Alternatively, you can directly append ?author=<theusername>
or ?author=<emailaddress>
to the URL. For example, https://github.com/jquery/jquery/commits/master?author=dmethvin or https://github.com/jquery/jquery/commits/[email protected] both give me:
For authors without a GitHub account, only filtering by email address will work, and you will need to manually add ?author=<emailaddress>
to the URL - the author's name will not be clickable from the commits list.
You can also get the list of commits by a particular author from the command line using
git log --author=[your git name]
Example:
git log --author=Prem
The error comes up when you are trying to assign a list of numpy array of different length to a data frame, and it can be reproduced as follows:
A data frame of four rows:
df = pd.DataFrame({'A': [1,2,3,4]})
Now trying to assign a list/array of two elements to it:
df['B'] = [3,4] # or df['B'] = np.array([3,4])
Both errors out:
ValueError: Length of values does not match length of index
Because the data frame has four rows but the list and array has only two elements.
Work around Solution (use with caution): convert the list/array to a pandas Series, and then when you do assignment, missing index in the Series will be filled with NaN:
df['B'] = pd.Series([3,4])
df
# A B
#0 1 3.0
#1 2 4.0
#2 3 NaN # NaN because the value at index 2 and 3 doesn't exist in the Series
#3 4 NaN
For your specific problem, if you don't care about the index or the correspondence of values between columns, you can reset index for each column after dropping the duplicates:
df.apply(lambda col: col.drop_duplicates().reset_index(drop=True))
# A B
#0 1 1.0
#1 2 5.0
#2 7 9.0
#3 8 NaN
For what it's worth I do miss the ^ operator when raising a power of 2 to define a binary constant. Can't use Math.Pow() there, but shifting an unsigned int of 1 to the left by the exponent's value works. When I needed to define a constant of (2^24)-1:
public static int Phase_count = 24;
public static uint PatternDecimal_Max = ((uint)1 << Phase_count) - 1;
Remember the types must be (uint) << (int).
A Runnable is basically a type of class (Runnable is an Interface) that can be put into a thread, describing what the thread is supposed to do.
The Runnable Interface requires of the class to implement the method run()
like so:
public class MyRunnableTask implements Runnable {
public void run() {
// do stuff here
}
}
And then use it like this:
Thread t = new Thread(new MyRunnableTask());
t.start();
If you did not have the Runnable
interface, the Thread class, which is responsible to execute your stuff in the other thread, would not have the promise to find a run()
method in your class, so you could get errors. That is why you need to implement the interface.
Note that you do not need to define a class as usual, you can do all of that inline:
Thread t = new Thread(new Runnable() {
public void run() {
// stuff here
}
});
t.start();
This is similar to the above, only you don't create another named class.
Can you change the if condition to this:
if (!is.na(comments[l])) print(comments[l]);
You can only check for NA values with is.na().
The first and the last, at least, are possible using the following syntax:
String.Format("{0,20}", "String goes here");
String.Format("{0,-20}", "String goes here");
This problem appears when we are using any third party solution, without using the handlers for the cleanup activitiy. For me this was happening for EhCache. We were using EhCache in our project for caching. And often we used to see following error in the logs
SEVERE: The web application [/products] appears to have started a thread named [products_default_cache_configuration] but has failed to stop it. This is very likely to create a memory leak.
Aug 07, 2017 11:08:36 AM org.apache.catalina.loader.WebappClassLoader clearReferencesThreads
SEVERE: The web application [/products] appears to have started a thread named [Statistics Thread-products_default_cache_configuration-1] but has failed to stop it. This is very likely to create a memory leak.
And we often noticed tomcat failing for OutOfMemory error during development where we used to do backend changes and deploy the application multiple times for reflecting our changes.
This is the fix we did
<listener>
<listener-class>
net.sf.ehcache.constructs.web.ShutdownListener
</listener-class>
</listener>
So point I am trying to make is check the documentation of the third party libraries which you are using. They should be providing some mechanisms to clean up the threads during shutdown. Which you need to use in your application. No need to re-invent the wheel unless its not provided by them. The worst case is to provide your own implementation.
Reference for EHCache Shutdown http://www.ehcache.org/documentation/2.8/operations/shutdown.html
The below command is enough to get the path of the file from a dialog box -
my_FileName = Application.GetOpenFilename("Excel Files (*.tsv), *.txt")

prints all keys one key per line without quotes.

cd
Converting my old comment for better visibility: For a "better way to do this" without map
entirely, if your inputs are known to be ASCII ordinals, it's generally much faster to convert to bytes
and decode, a la bytes(list_of_ordinals).decode('ascii')
. That gets you a str
of the values, but if you need a list
for mutability or the like, you can just convert it (and it's still faster). For example, in ipython
microbenchmarks converting 45 inputs:
>>> %%timeit -r5 ordinals = list(range(45))
... list(map(chr, ordinals))
...
3.91 µs ± 60.2 ns per loop (mean ± std. dev. of 5 runs, 100000 loops each)
>>> %%timeit -r5 ordinals = list(range(45))
... [*map(chr, ordinals)]
...
3.84 µs ± 219 ns per loop (mean ± std. dev. of 5 runs, 100000 loops each)
>>> %%timeit -r5 ordinals = list(range(45))
... [*bytes(ordinals).decode('ascii')]
...
1.43 µs ± 49.7 ns per loop (mean ± std. dev. of 5 runs, 1000000 loops each)
>>> %%timeit -r5 ordinals = list(range(45))
... bytes(ordinals).decode('ascii')
...
781 ns ± 15.9 ns per loop (mean ± std. dev. of 5 runs, 1000000 loops each)
If you leave it as a str
, it takes ~20% of the time of the fastest map
solutions; even converting back to list it's still less than 40% of the fastest map
solution. Bulk convert via bytes
and bytes.decode
then bulk converting back to list
saves a lot of work, but as noted, only works if all your inputs are ASCII ordinals (or ordinals in some one byte per character locale specific encoding, e.g. latin-1
).
The -i
flag specifies the private key (.pem file) to use. If you don't specify that flag (as in your first command) it will use your default ssh key (usually under ~/.ssh/
).
So in your first command, you are actually asking scp
to upload the .pem file itself using your default ssh key. I don't think that is what you want.
Try instead with:
scp -r -i /Applications/XAMPP/htdocs/keypairfile.pem uploads/* ec2-user@publicdns:/var/www/html/uploads
There are four cases.
:focus
(without active).:active
(without focus).:active:focus
(active and focus simultaneously).Example:
<div>
I cannot be focused.
</div>
<div tabindex="0">
I am focusable.
</div>
div:focus {
background: green;
}
div:active {
color: orange;
}
div:focus:active {
font-weight: bold;
}
When the page loads both are in case 1. When you press tab you will focus the second div and see it exhibit case 2. When you click on the first div you see case 3. When you click the second div, you see case 4.
Whether an element is focusable or not is another question. Most are not by default. But, it's safe to assume <a>
, <input>
, <textarea>
are focusable by default.
say you want to split into 5 parts:
p1, p2, p3, p4, p5 = np.split(df, 5)
See adeneo's answer, but to make this work in Excel in all countries you should add "SEP=," to the first line of the file. This will set the standard separator in Excel and will not show up in the actual document
var csvString = "SEP=, \n" + csvRows.join("\r\n");
You can take database back-up of SQL server instance using C#, as below
Step 1: Install Nuget package "Install-Package Microsoft.SqlServer.SqlManagementObjects
"
Step 2: Use the below C# Command to take backup using Custom function

{
//Define a Backup object variable.
Backup sqlBackup = new Backup();
//Specify the type of backup, the description, the name, and the database to be backed up.
sqlBackup.Action = BackupActionType.Database;
sqlBackup.BackupSetDescription = "BackUp of:" + databaseName + "on" + DateTime.Now.ToShortDateString();
sqlBackup.BackupSetName = "FullBackUp";
sqlBackup.Database = databaseName;
//Declare a BackupDeviceItem
BackupDeviceItem deviceItem = new BackupDeviceItem(destinationPath + "FullBackUp.bak", DeviceType.File);
//Define Server connection
ServerConnection connection = new ServerConnection(serverName, userName, password); //To Avoid TimeOut Exception
Server sqlServer = new Server(connection);
sqlServer.ConnectionContext.StatementTimeout = 60 * 60;
Database db = sqlServer.Databases[databaseName];
(Reference Database As microsoft.sqlserver.management.smo.database, not as System.entity.database)

sqlBackup.Checksum = true;
sqlBackup.ContinueAfterError = true;
//Add the device to the Backup object.
sqlBackup.Devices.Add(deviceItem);

A lot of answers are deprecated so I'll update the thread and show how to change text color and backgroundcolor on ActionBar (Toolbar) and in ActionBar pop up menu.
The latest approach in Android (as of May 2018) in working with Action bar (Toolbar) is to use Theme with NoActionBar and use Toolbar instead.
so here is what you need:
In Activity (which extends AppCompatActivity) declare Toolbar:
Toolbar myToolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(myToolbar);
Add Toolbar in the Activity's layout xml. Here we will set our custom (overwritten themes), note android:theme="@style/ThemeOverlay.AppTheme.ActionBar"
and app:popupTheme="@style/ThemeOverlay.AppTheme.PopupMenu"
, they will do the trick.
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="?attr/actionBarSize"
android:theme="@style/ThemeOverlay.AppTheme.ActionBar"
app:popupTheme="@style/ThemeOverlay.AppTheme.PopupMenu"
app:layout_constraintTop_toTopOf="parent" />
In your styles.xml you will have to overwrite those two styles to set custom colors:
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="actionBarTheme">@style/ThemeOverlay.AppTheme.ActionBar</item>
<item name="actionBarPopupTheme">@style/ThemeOverlay.AppTheme.PopupMenu</item>
</style>
<style name="ThemeOverlay.AppTheme.ActionBar" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
<item name="android:textColorPrimary">@color/action_bar_text_color</item>
<item name="android:background">@color/action_bar_bg_color</item>
</style>
<style name="ThemeOverlay.AppTheme.PopupMenu" parent="ThemeOverlay.AppCompat.Dark.ActionBar">
<item name="android:background">@color/popup_bg_color</item>
<item name="android:textColorPrimary">@color/popup_text_color</item>
</style>
That's it folks
p.s. if you ask me I would say: YES, this whole Theme thing is a hell of a mess.

As of November 2016, this is a little rough around the edges, but displays the basic principle. The url_encoded_fmt_stream_map today does not have a space after the colon (better make this optional) and "

Some time This Code Not worked proper
Same-origin policy
https://en.wikipedia.org/wiki/Same-origin_policy
https://en.wikipedia.org/wiki/Cross-origin_resource_sharing
problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is [CORS][1].
url_encoded_fmt_stream_map // traditional: contains video and audio stream
adaptive_fmts // DASH: contains video or audio stream
Each of these is a comma separated array of what I would call "stream objects". Each "stream object" will contain values like this
url // direct HTTP link to a video
itag // code specifying the quality
s // signature, security measure to counter downloading
Each URL will be encoded so you will need to decode them. Now the tricky part.
YouTube has at least 3 security levels for their videos
unsecured // as expected, you can download these with just the unencoded URL
s // see below
RTMPE // uses "rtmpe://" protocol, no known method for these
The RTMPE videos are typically used on official full length movies, and are protected with SWF Verification Type 2. This has been around since 2011 and has yet to be reverse engineered.
The type "s" videos are the most difficult that can actually be downloaded. You will typcially see these on VEVO videos and the like. They start with a signature such as
AA5D05FA7771AD4868BA4C977C3DEAAC620DE020E.0F421820F42978A1F8EAFCDAC4EF507DB5 Then the signature is scrambled with a function like this
function mo(a) {
a = a.split("");
a = lo.rw(a, 1);
a = lo.rw(a, 32);
a = lo.IC(a, 1);
a = lo.wS(a, 77);
a = lo.IC(a, 3);
a = lo.wS(a, 77);
a = lo.IC(a, 3);
a = lo.wS(a, 44);
return a.join("")
}
This function is dynamic, it typically changes every day. To make it more difficult the function is hosted at a URL such as
http://s.ytimg.com/yts/jsbin/html5player-en_US-vflycBCEX.js
this introduces the problem of Same-origin policy. Essentially, you cannot download this file from www.youtube.com because they are different domains. A workaround of this problem is CORS. With CORS, s.ytimg.com could add this header
Access-Control-Allow-Origin: http://www.youtube.com
and it would allow the JavaScript to download from www.youtube.com. Of course they do not do this. A workaround for this workaround is to use a CORS proxy. This is a proxy that responds with the following header to all requests
Access-Control-Allow-Origin: *
So, now that you have proxied your JS file, and used the function to scramble the signature, you can use that in the querystring to download a video.
You can compare the length of the string with one where the commas are removed:
len(value) - len(replace(value,',',''))
Before jumping into any further error checking please first check whether its
document.getElementsByClassName() itself.
double check its getElements and not getElement
I am using AutoMapper 6.1.1 and asp.net Core 1.1.2.
First of all, define Profile classes inherited by Profile Class of Automapper. I Created IProfile interface which is empty, the purpose is only to find the classes of this type.
public class UserProfile : Profile, IProfile
{
public UserProfile()
{
CreateMap<User, UserModel>();
CreateMap<UserModel, User>();
}
}
Now create a separate class e.g Mappings
public class Mappings
{
public static void RegisterMappings()
{
var all =
Assembly
.GetEntryAssembly()
.GetReferencedAssemblies()
.Select(Assembly.Load)
.SelectMany(x => x.DefinedTypes)
.Where(type => typeof(IProfile).GetTypeInfo().IsAssignableFrom(type.AsType()));
foreach (var ti in all)
{
var t = ti.AsType();
if (t.Equals(typeof(IProfile)))
{
Mapper.Initialize(cfg =>
{
cfg.AddProfiles(t); // Initialise each Profile classe
});
}
}
}
}
Now in MVC Core web Project in Startup.cs file, in the constructor, call Mapping class which will initialize all mappings at the time of application loading.
Mappings.RegisterMappings();
When you create an App, a file called styles.xml will be created in your res/values folder. If you change the styles, you can change the background, text color, etc for all your layouts. That way you don’t have to go into each individual layout and change the it manually.
styles.xml:
<resources xmlns:android="http://schemas.android.com/apk/res/android">
<style name="Theme.AppBaseTheme" parent="@android:style/Theme.Light">
<item name="android:editTextColor">#295055</item>
<item name="android:textColorPrimary">#295055</item>
<item name="android:textColorSecondary">#295055</item>
<item name="android:textColorTertiary">#295055</item>
<item name="android:textColorPrimaryInverse">#295055</item>
<item name="android:textColorSecondaryInverse">#295055</item>
<item name="android:textColorTertiaryInverse">#295055</item>
<item name="android:windowBackground">@drawable/custom_background</item>
</style>
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>
parent="@android:style/Theme.Light"
is Google’s native colors. Here is a reference of what the native styles are:
https://android.googlesource.com/platform/frameworks/base/+/refs/heads/master/core/res/res/values/themes.xml
The default Android style is also called “Theme”. So you calling it Theme probably confused the program.
name="Theme.AppBaseTheme"
means that you are creating a style that inherits all the styles from parent="@android:style/Theme.Light"
.
This part you can ignore unless you want to inherit from AppBaseTheme again. = <style name="AppTheme" parent="AppBaseTheme">
@drawable/custom_background is a custom image I put in the drawable’s folder. It is a 300x300 png image.
#295055 is a dark blue color.
My code changes the background and text color. For Button text, please look through Google’s native stlyes (the link I gave u above).
Then in Android Manifest, remember to include the code:
<application
android:theme="@style/Theme.AppBaseTheme">
HTTP Basic Access Authentication
Basic Authentication uses base64 encoding(not encryption) for generating our cryptographic string which contains the information of username and password. HTTP Basic doesn’t need to be implemented over SSL, but if you don’t, it isn’t secure at all. So I’m not even going to entertain the idea of using it without.
Pros:
Cons:
In Summary – if you have control of the clients, or can ensure they use SSL, HTTP Basic is a good choice. The slowness of the SSL can be cancelled out by the speed of only making one request
Syntax of basic Authentication
Value = username:password
Encoded Value = base64(Value)
Authorization Value = Basic <Encoded Value>
//at last Authorization key/value map added to http header as follows
Authorization: <Authorization Value>
HTTP Digest Access Authentication
Digest Access Authentication uses the hashing(i.e digest means cut into small pieces) methodologies to generate the cryptographic result. HTTP Digest access authentication is a more complex form of authentication that works as follows:
Pros:
Cons:
In Summary, HTTP Digest is inherently vulnerable to at least two attacks, whereas a server using strong encryption for passwords with HTTP Basic over SSL is less likely to share these vulnerabilities.
If you don’t have control over your clients however they could attempt to perform Basic authentication without SSL, which is much less secure than Digest.
RFC 2069 Digest Access Authentication Syntax
Hash1=MD5(username:realm:password)
Hash2=MD5(method:digestURI)
response=MD5(Hash1:nonce:Hash2)
RFC 2617 Digest Access Authentication Syntax
Hash1=MD5(username:realm:password)
Hash2=MD5(method:digestURI)
response=MD5(Hash1:nonce:nonceCount:cnonce:qop:Hash2)
//some additional parameters added
In Postman looks as follows:
Note:
With 500k documents, there is no reason to scale whatsoever. A typical laptop with an SSD and 8GB of ram can easily do 10s of millions of records, so if you are trying to pick because of scaling your choice doesn't really matter. I would suggest you pick what you like the most, and perhaps where you can find the most online support with.
For me once I disabled MTP (in Settings>Storage>Menu>MTP) I finally got the RSA prompt
No, and the fact that you want to seems like a bad idea. Do you really need a default constructor like this?
I had a similar problem . For this you can use a Hashmap which takes "string" and "object" as shown in code below:
/** stores the image database icons */
public static int[] imageIconDatabase = { R.drawable.ball,
R.drawable.catmouse, R.drawable.cube, R.drawable.fresh,
R.drawable.guitar, R.drawable.orange, R.drawable.teapot,
R.drawable.india, R.drawable.thailand, R.drawable.netherlands,
R.drawable.srilanka, R.drawable.pakistan,
};
private void initializeImageList() {
// TODO Auto-generated method stub
for (int i = 0; i < imageIconDatabase.length; i++) {
map = new HashMap<String, Object>();
map.put("Name", imageNameDatabase[i]);
map.put("Icon", imageIconDatabase[i]);
}
}
HTML5 has several goals which differentiate it from HTML4.
The primary one is consistent, defined error handling. As you know, HTML purposely supports 'tag soup', or the ability to write malformed code and have it corrected into a valid document. The problem is that the rules for doing this aren't written down anywhere. When a new browser vendor wants to enter the market, they just have to test malformed documents in various browsers (especially IE) and reverse-engineer their error handling. If they don't, then many pages won't display correctly (estimates place roughly 90% of pages on the net as being at least somewhat malformed).
So, HTML5 is attempting to discover and codify this error handling, so that browser developers can all standardize and greatly reduce the time and money required to display things consistently. As well, long in the future after HTML has died as a document format, historians may still want to read our documents, and having a completely defined parsing algorithm will greatly aid this.
The secondary goal of HTML5 is to develop the ability of the browser to be an application platform, via HTML, CSS, and Javascript. Many elements have been added directly to the language that are currently (in HTML4) Flash or JS-based hacks, such as <canvas>
, <video>
, and <audio>
. Useful things such as Local Storage (a js-accessible browser-built-in key-value database, for storing information beyond what cookies can hold), new input types such as date for which the browser can expose easy user interface (so that we don't have to use our js-based calendar date-pickers), and browser-supported form validation will make developing web applications much simpler for the developers, and make them much faster for the users (since many things will be supported natively, rather than hacked in via javascript).
There are many other smaller efforts taking place in HTML5, such as better-defined semantic roles for existing elements (<strong>
and <em>
now actually mean something different, and even <b>
and <i>
have vague semantics that should work well when parsing legacy documents) and adding new elements with useful semantics - <article>
, <section>
, <header>
, <aside>
, and <nav>
should replace the majority of <div>
s used on a web page, making your pages a bit more semantic, but more importantly, easier to read. No more painful scanning to see just what that random </div>
is closing - instead you'll have an obvious </header>
, or </article>
, making the structure of your document much more intuitive.
Craig Stuntz has written an extensive (in my opinion) blog post on troubleshooting this exact error message, I personally would start there.

res://*/Models.WraithNath.co.uk.csdl|
res://*/Models.WraithNath.co.uk.ssdl|
res://*/Models.WraithNath.co.uk.msl;
Make sure each one has the name of your .edmx file after the "*/", with the "edmx" changed to the extension for that res (.csdl, .ssdl, or .msl).
It also may help to specify the assembly rather than using "//*/".
Worst case, you can check everything (a bit slower but should always find the resource) by using
<add name="Entities" connectionString="metadata=
res://*/;provider= <!-- ... -->
If all the previous answers didn't give any solution, you should check your user privileges.
If you could login as root
to mysql
then you should add this:
CREATE USER 'root'@'192.168.1.100' IDENTIFIED BY '***';
GRANT ALL PRIVILEGES ON * . * TO 'root'@'192.168.1.100' IDENTIFIED BY '***' WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;
Then try to connect again using mysql -ubeer -pbeer -h192.168.1.100
. It should work.
Python Static methods can be created in two ways.
Using staticmethod()
class Arithmetic:
def add(x, y):
return x + y
# create add static method
Arithmetic.add = staticmethod(Arithmetic.add)
print('Result:', Arithmetic.add(15, 10))
Output:
Result: 25
Using @staticmethod
class Arithmetic:
# create add static method
@staticmethod
def add(x, y):
return x + y
print('Result:', Arithmetic.add(15, 10))
Output:
Result: 25
Resolved this issue for vue, by adding to the options an id: 'alertBox'
so now every modal container has its parent set to something like alertBox__id0whatver
which can easily be changed with css:
div[id*="alertBox"] { background: red; }
(meaning if id name contains ( *=
) 'alertBox' it will be applied.
With Django version 1.3, the class based approach is:
from django.conf.urls.defaults import patterns, url
from django.views.generic import RedirectView
urlpatterns = patterns('',
url(r'^some-url/$', RedirectView.as_view(url='/redirect-url/'), name='some_redirect'),
)
This example lives in in urls.py
You can easily make your own 'AlertView' and use it everywhere.
alertView("You really want this?");
Implement it once:
private void alertView( String message ) {
AlertDialog.Builder dialog = new AlertDialog.Builder(context);
dialog.setTitle( "Hello" )
.setIcon(R.drawable.ic_launcher)
.setMessage(message)
// .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
// public void onClick(DialogInterface dialoginterface, int i) {
// dialoginterface.cancel();
// }})
.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialoginterface, int i) {
}
}).show();
}
add:
.SubItems.Add("asdasdasd");
to the last line of your code so it will look like this in the end.
listView1.Items.Add("sdasdasdasd").SubItems.Add("asdasdasd");
I got the similar requirement and got help from reading few of the above solutions and across other websites, I have came up with below script, Just wanted to share if it might help anyone.
from boto3.session import Session
import os
def sync_s3_folder(access_key_id,secret_access_key,bucket_name,folder,destination_path):
session = Session(aws_access_key_id=access_key_id,aws_secret_access_key=secret_access_key)
s3 = session.resource('s3')
your_bucket = s3.Bucket(bucket_name)
for s3_file in your_bucket.objects.all():
if folder in s3_file.key:

your_bucket.download_file(s3_file.key,file)
sync_s3_folder(access_key_id,secret_access_key,bucket_name,folder,destination_path)
you have to call a function before it can return anything.
function mainFunction() {
function subFunction() {
var str = "foo";
return str;
}
return subFunction();
}
var test = mainFunction();
alert(test);
Or:
function mainFunction() {
function subFunction() {
var str = "foo";
return str;
}
return subFunction;
}
var test = mainFunction();
alert( test() );
for your actual code. The return should be outside, in the main function. The callback is called somewhere inside the getLocations
method and hence its return value is not recieved inside your main function.
function reverseGeocode(latitude,longitude){
var address = "";
var country = "";
var countrycode = "";
var locality = "";
var geocoder = new GClientGeocoder();
var latlng = new GLatLng(latitude, longitude);
geocoder.getLocations(latlng, function(addresses) {
address = addresses.Placemark[0].address;
country = addresses.Placemark[0].AddressDetails.Country.CountryName;
countrycode = addresses.Placemark[0].AddressDetails.Country.CountryNameCode;
locality = addresses.Placemark[0].AddressDetails.Country.AdministrativeArea.SubAdministrativeArea.Locality.LocalityName;
});
return country

There is a much simpler way to do it using seaborn:

sns.distplot(data)
plt.show()

This code worked for me. I had to add TLS2 because that's what the URL I am interested in was using.
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
ServicePointManager.ServerCertificateValidationCallback +=
(sender, cert, chain, sslPolicyErrors) => { return true; };
using (var client = new HttpClient())
{
client.BaseAddress = new Uri(UserDataUrl);
client.DefaultRequestHeaders.Accept.Clear();
client.DefaultRequestHeaders.Accept.Add(new
MediaTypeWithQualityHeaderValue("application/json"));
Task<string> response = client.GetStringAsync(UserDataUrl);
response.Wait();
if (response.Exception != null)
{
return null;
}
return JsonConvert.DeserializeObject<UserData>(response.Result);
}
This is how I fixed it:
import os
import sys
module_path = os.path.abspath(os.getcwd() + '\\..')
if module_path not in sys.path:
sys.path.append(module_path)
I would consider this more of an old-school C style; it is not really good practice in JavaScript so you should avoid it.
It's not exactly clear how you want to search the array. Here are some alternatives:
Find all items containing the exact string "Ra" (returns items 2 and 3):
Dim result As String() = Array.FindAll(arr, Function(s) s.Contains("Ra"))
Find all items starting with the exact string "Ra" (returns items 2 and 3):
Dim result As String() = Array.FindAll(arr, Function(s) s.StartsWith("Ra"))
Find all items containing any case version of "ra" (returns items 0, 2 and 3):
Dim result As String() = Array.FindAll(arr, Function(s) s.ToLower().Contains("ra"))
Find all items starting with any case version of "ra" (retuns items 0, 2 and 3):
Dim result As String() = Array.FindAll(arr, Function(s) s.ToLower().StartsWith("ra"))
-
If you are not using VB 9+ then you don't have anonymous functions, so you have to create a named function.
Example:
Function ContainsRa(s As String) As Boolean
Return s.Contains("Ra")
End Function
Usage:
Dim result As String() = Array.FindAll(arr, ContainsRa)
Having a function that only can compare to a specific string isn't always very useful, so to be able to specify a string to compare to you would have to put it in a class to have somewhere to store the string:
Public Class ArrayComparer
Private _compareTo As String
Public Sub New(compareTo As String)
_compareTo = compareTo
End Sub
Function Contains(s As String) As Boolean
Return s.Contains(_compareTo)
End Function
Function StartsWith(s As String) As Boolean
Return s.StartsWith(_compareTo)
End Function
End Class
Usage:
Dim result As String() = Array.FindAll(arr, New ArrayComparer("Ra").Contains)
Here's a nice function template using C++11 magic, working for both std::map, std::unordered_map:
template<template <typename...> class MAP, class KEY, class VALUE>
std::vector<KEY>
keys(const MAP<KEY, VALUE>& map)
{
std::vector<KEY> result;
result.reserve(map.size());
for(const auto& it : map){
result.emplace_back(it.first);
}
return result;
}

I use RStudio or Emacs and always use the editor shortcuts available to comment regions. If this is not a possibility then you could use Paul's answer but this only works if your code is syntactically correct.
Here is another dirty way I came up with, wrap it in scan()
and remove the result. It does store the comment in memory for a short while so it will probably not work with very large comments. Best still is to just put #
signs in front of every line (possibly with editor shortcuts).
foo <- scan(what="character")
These are comments
These are still comments
Can also be code:
x <- 1:10
One line must be blank
rm(foo)
I am just throwing in another one for reference since there was an additional question to Mark Edgars input and here is an additional example and touches on the topic overall:
[[ `cmd` ]] && echo success_else_silence
Which is the same as cmd || exit errcode
as someone showed.
For example, I want to make sure a partition is unmounted if mounted:
[[ `mount | grep /dev/sda1` ]] && umount /dev/sda1
I don't like and understand things, which can be explained visually, by words.
int intlen(int integer){
int a;
for(a = 1; integer /= 10; a++);
return a;
}
Give name and values to those submit buttons like:
<td>
<input type="submit" name='mybutton' class="noborder" id="save" value="save" alt="Save" tabindex="4" />
</td>
<td>
<input type="submit" name='mybutton' class="noborder" id="publish" value="publish" alt="Publish" tabindex="5" />
</td>
and then in your php script you could check
if($_POST['mybutton'] == 'save')
{
///do save processing
}
elseif($_POST['mybutton'] == 'publish')
{
///do publish processing here
}
To simplify Amiram Korach's solution:
dtList.RemoveAll(s => string.IsNullOrWhiteSpace(s))
No need to use Distinct() or ToList()
Try this:
document.addEventListener("keydown", KeyCheck); //or however you are calling your method
function KeyCheck(event)
{
var KeyID = event.keyCode;
switch(KeyID)
{
case 8:
alert("backspace");
break;
case 46:
alert("delete");
break;
default:
break;
}
}
I am not certain about what precisely you are trying to do, but I think this SQL function will help you:
SELECT DATEADD(day,-1,'2013-04-01 16:25:00.250')
The above will give you 2013-03-31 16:25:00.250
.
It takes you back exactly one day and works on any standard date-time or date format.
Try running this command and see if it gives you what you are looking for:
SELECT DATEADD(day,-1,@CreatedDate)
CASE WHEN B.[STAT] IS NULL THEN (C.[EVENT DATE]+10) -- Type DATETIME
ELSE '-' -- Type VARCHAR
END AS [DATE]
You need to select one type or the other for the field, the field type can't vary by row.
The simplest is to remove the ELSE '-'
and let it implicitly get the value NULL
instead for the second case.
I am going to use this one. Very similar to third one shown by @Marin.

Though this question is rather old, here's a answer :)
What you are asking for can be achieved by using jQuery's .click() event method and .on() event method
So this could be the code:
// Set the global variables
var userImage = $("#img-giLkojRpuK");
var hangoutButton = $("#hangout-giLkojRpuK");
$(document).ready(function() {
// When the document is ready/loaded, execute function
// Hide hangoutButton
hangoutButton.hide();
// Assign "click"-event-method to userImage
userImage.on("click", function() {
console.log("in onclick");
hangoutButton.click();
});
});
Imagine you are the manager of a software company and you just bought a brand new server. Just the hardware.
Think of Dockerfile
as a set of instructions you would tell your system adminstrator what to install on this brand new server. For example:
/var/www
)By contrast, think of docker-compose.yml
as a set of instructions you would tell your system administrator how the server can interact with the rest of the world. For example,
(This is not a precise explanation but good enough to start with.)
You best see if you have a parent element of the div you are querying. If so get the parent element and perform an element.querySelectorAll("div")
. Once you get the nodeList
apply a filter on it over the innerText
property. Assume that a parent element of the div that we are querying has an id
of container
. You can normally access container directly from the id but let's do it the proper way.
var conty = document.getElementById("container"),
divs = conty.querySelectorAll("div"),
myDiv = [...divs].filter(e => e.innerText == "SomeText");
So that's it.
iPad Multitasking support requires all the orientations but your app does not, so you need to opt out of it, just add the UIRequiresFullScreen
key to your Xcode project’s Info.plist
file and apply the Boolean value YES
.
The least complicated, most straight-forward way of doing this is by simply wrapping your main query with the pivot in a common table expression, then grouping/aggregating.
WITH PivotCTE AS
(
select * from mytransactions
pivot (sum (totalcount) for country in ([Australia], [Austria])) as pvt
)
SELECT
numericmonth,
chardate,
SUM(totalamount) AS totalamount,
SUM(ISNULL(Australia, 0)) AS Australia,
SUM(ISNULL(Austria, 0)) Austria
FROM PivotCTE
GROUP BY numericmonth, chardate
The ISNULL
is to stop a NULL
value from nullifying the sum (because NULL
+ any value = NULL
)
The short answer
The simple answer is: No, there is no generic means to determine that an object is equal to another in the sense you mean. The exception is when you are strictly thinking of an object being typeless.
The long answer
The concept is that of an Equals method that compares two different instances of an object to indicate whether they are equal at a value level. However, it is up to the specific type to define how an Equals
method should be implemented. An iterative comparison of attributes that have primitive values may not be enough, there may well be attributes which are not to be considered part of the object value. For example,
function MyClass(a, b)
{
var c;
this.getCLazy = function() {
if (c === undefined) c = a * b // imagine * is really expensive
return c;
}
}
In this above case, c
is not really important to determine whether any two instances of MyClass are equal, only a
and b
are important. In some cases c
might vary between instances and yet not be significant during comparison.
Note this issue applies when members may themselves also be instances of a type and these each would all be required to have a means of determining equality.
Further complicating things is that in JavaScript the distinction between data and method is blurred.
An object may reference a method that is to be called as an event handler, and this would likely not be considered part of its 'value state'. Whereas another object may well be assigned a function that performs an important calculation and thereby makes this instance different from others simply because it references a different function.
What about an object that has one of its existing prototype methods overridden by another function? Could it still be considered equal to another instance that it otherwise identical? That question can only be answered in each specific case for each type.
As stated earlier, the exception would be a strictly typeless object. In which case the only sensible choice is an iterative and recursive comparison of each member. Even then one has to ask what is the 'value' of a function?
An Enumerator
shows you the items in a list or collection.
Each instance of an Enumerator is at a certain position (the 1st element, the 7th element, etc) and can give you that element (IEnumerator.Current
) or move to the next one (IEnumerator.MoveNext
). When you write a foreach
loop in C#, the compiler generates code that uses an Enumerator.
An Enumerable
is a class that can give you Enumerator
s. It has a method called GetEnumerator
which gives you an Enumerator
that looks at its items. When you write a foreach
loop in C#, the code that it generates calls GetEnumerator
to create the Enumerator
used by the loop.
If you want more compact code, I suggest using Apache Commons DbUtils. In this case:
Connection conn = null;
PreparedStatement stmt = null;
ResultSet rs = null;
try {
conn = // Retrieve connection
stmt = conn.prepareStatement(// Some SQL);
rs = stmt.executeQuery();
} catch(Exception e) {
// Error Handling
} finally {
DbUtils.closeQuietly(rs);
DbUtils.closeQuietly(stmt);
DbUtils.closeQuietly(conn);
}
You can try the above way to activate a profile
You can write DateTime? newdate = null;
It should be implemented as a free, non-friend functions, especially if, like most things these days, the output is mainly used for diagnostics and logging. Add const accessors for all the things that need to go into the output, and then have the outputter just call those and do formatting.
I've actually taken to collecting all of these ostream output free functions in an "ostreamhelpers" header and implementation file, it keeps that secondary functionality far away from the real purpose of the classes.
Note: this solution works only if the slaves have the same directory structure as the master. pwd()
will return the workspace directory on the master due to JENKINS-33511.
I used to do it using pwd()
functionality of pipeline plugin. So, if you need to get a workspace on slave, you may do smth like this:
node('label'){
//now you are on slave labeled with 'label'
def workspace = pwd()
//${workspace} will now contain an absolute path to job workspace on slave
}
I would probably do something along the lines of
<div id='search-logo-bar'><input type='text'/></div>
with css
div#search-logo-bar {
padding-left:10%;
background:#333 url(logo.png) no-repeat left center;
background-size:10%;
}
input[type='text'] {
display:block;
width:100%;
}

I was trying to find the meaning of GRANT USAGE on *.* TO
and found here. I can clarify that GRANT USAGE on *.* TO user IDENTIFIED BY PASSWORD password
will be granted when you create the user with the following command (CREATE

CREATE USER 'user'@'localhost' IDENTIFIED BY 'password';
When you grant privilege with GRANT
, new privilege s will be added on top of it.
While @dfa answer of org.apache.commons.lang.StringEscapeUtils.escapeHtml
is nice and I have used it in the past it should not be used for escaping HTML (or XML) attributes otherwise the whitespace will be normalized (meaning all adjacent whitespace characters become a single space).
I know this because I have had bugs filed against my library (JATL) for attributes where whitespace was not preserved. Thus I have a drop in (copy n' paste) class (of which I stole some from JDOM) that differentiates the escaping of attributes and element content.
While this may not have mattered as much in the past (proper attribute escaping) it is increasingly become of greater interest given the use use of HTML5's data-
attribute usage.
Make sure you are using the SSH URL for the GitHub repository rather than the HTTPS URL. It will ask for username and password when you are using HTTPS and not SSH. You can check the file .git/config

or git remote show origin
to verify the URL and change it if needed.
You want:
DECLARE @times int

You also don't need the 'as' clause.
I encounter this error when I'm querying an entry of another domain of the forrest and this entry have some custom attribut of the other domain.

My solution was to change the layout file from

If this is your app, if you connect the device to your computer, you can use the "Devices" option on Xcode's "Window" menu and then download the app's data container to your computer. Just select your app from the list of installed apps, and click on the "gear" icon and choose "Download Container".
Once you've downloaded it, right click on the file in the Finder and choose "Show Package Contents".
I have added a distribution to the Python Package Index which makes the match_hostname()
function from the Python 3.2 ssl
package available on previous versions of Python.
http://pypi.python.org/pypi/backports.ssl_match_hostname/
You can install it with:
pip install backports.ssl_match_hostname
Or you can make it a dependency listed in your project's setup.py
. Either way, it can be used like this:
from backports.ssl_match_hostname import match_hostname, CertificateError
...
sslsock = ssl.wrap_socket(sock, ssl_version=ssl.PROTOCOL_SSLv3,
cert_reqs=ssl.CERT_REQUIRED, ca_certs=...)
try:
match_hostname(sslsock.getpeercert(), hostname)
except CertificateError, ce:

from the String

and split each element by =

put each part separated by =

Better yet, use union to grab all the rows you want to delete, then delete them all at once. The rows need not be continuous.
dim rng as range
dim rDel as range
for each rng in {the range you're searching}
if {Conditions to be met} = true then
if not rDel is nothing then
set rDel = union(rng,rDel)
else
set rDel = rng
end if
end if
next
rDel.entirerow.delete
That way you don't have to worry about sorting or things being at the bottom.
Scala is supported. See example.
Support for other languages is problematic:
7) Something like the dx tool can be forced into the phone, so that Java code could in principle continue to generate bytecodes, yet have them be translated into a VM-runnable form. But, at present, Java code cannot be generated on the fly. This means Dalvik cannot run dynamic languages (JRuby, Jython, Groovy). Yet. (Perhaps the dex format needs a detuned variant which can be easily generated from bytecodes.)
What Works For Me is :
if ( !refreshed()) {
//Your Submit Here
if (isset( $_GET['refresh'])) {
setcookie("refresh",$_GET['refresh'], time() + (86400 * 5), "/");
}
}
}
function refreshed()
{
if (isset($_GET['refresh'])) {
$token = $_GET['refresh'];
if (isset($_COOKIE['refresh'])) {
if ($_COOKIE['refresh'] != $token) {
return false;
} else {
return true;
}
} else {
return false;
}
} else {
return false;
}
}
function createToken($length) {
$characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
$charactersLength = strlen($characters);
$randomString = '';
for ($i = 0; $i < $length; $i++) {
$randomString .= $characters[rand(0, $charactersLength - 1)];
}
return $randomString;
}
?>
And in your Form
<form action="?refresh=<?php echo createToken(3)?>">
</form>
For those running in such issues right now, just try to put an alias for the table, this should the trick, e.g:
SELECT myvalue
INTO myvar
FROM mytable x
WHERE x.anothervalue = 1;
It worked for me.
Cheers.
You want to use the array_key_exists function.
I think I am a bit late to the party but... In my opinion, what you need is the object oriented API of matplotlib. In matplotlib 1.4.2 and using IPython 2.4.1 with Qt4Agg backend, I can do the following:
import matplotlib.pyplot as plt
fig, ax = plt.subplots(1) # Creates figure fig and add an axes, ax.
fig2, ax2 = plt.subplots(1) # Another figure
ax.plot(range(20)) #Add a straight line to the axes of the first figure.
ax2.plot(range(100)) #Add a straight line to the axes of the first figure.
fig.show() #Only shows figure 1 and removes it from the "current" stack.
fig2.show() #Only shows figure 2 and removes it from the "current" stack.
plt.show() #Does not show anything, because there is nothing in the "current" stack.
fig.show() # Shows figure 1 again. You can show it as many times as you want.
In this case plt.show() shows anything in the "current" stack. You can specify figure.show() ONLY if you are using a GUI backend (e.g. Qt4Agg). Otherwise, I think you will need to really dig down into the guts of matplotlib to monkeypatch a solution.
Remember that most (all?) plt.* functions are just shortcuts and aliases for figure and axes methods. They are very useful for sequential programing, but you will find blocking walls very soon if you plan to use them in a more complex way.

The jQuery trick doesn't encode quote marks and in IE it will strip your whitespace.
Based on the escape templatetag in Django, which I guess is heavily used/tested already, I made this function which does what's needed.
It's arguably simpler (and possibly faster) than any of the workarounds for the whitespace-stripping issue - and it encodes quote marks, which is essential if you're going to use the result inside an attribute value for example.
function htmlEscape(str) {
return str
.replace(/&/g, '&')
.replace(/"/g, '"')
.replace(/'/g, ''')
.replace(/</g, '<')
.replace(/>/g, '>');
}
// I needed the opposite function today, so adding here too:
function htmlUnescape(str){
return str
.replace(/"/g, '"')
.replace(/'/g, "'")
.replace(/</g, '<')
.replace(/>/g, '>')
.replace(/&/g, '&');
}
Update 2013-06-17:
In the search for the fastest escaping I have found this implementation of a replaceAll
method:
http://dumpsite.com/forum/index.php?topic=4.msg29#msg29
(also referenced here: Fastest method to replace all instances of a character in a string)
Some performance results here:
http://jsperf.com/htmlencoderegex/25
It gives identical result string to the builtin replace
chains above. I'd be very happy if someone could explain why it's faster!?
Update 2015-03-04:
I just noticed that AngularJS are using exactly the method above:
https://github.com/angular/angular.js/blob/v1.3.14/src/ngSanitize/sanitize.js#L435
They add a couple of refinements - they appear to be handling an obscure Unicode issue as well as converting all non-alphanumeric characters to entities. I was under the impression the latter was not necessary as long as you have an UTF8 charset specified for your document.
I will note that (4 years later) Django still does not do either of these things, so I'm not sure how important they are:

You may also wish to escape forward-slash /
. This is not required for correct HTML encoding, however it is recommended by OWASP as an anti-XSS safety measure. (thanks to @JNF for suggesting this in comments)
.replace(/\//g, '/');
I'm a little confused. "foo.html" is just the name of your template. There's no inherent relationship between the route name "foo" and the template name "foo.html".
To achieve the goal of not rewriting logic code for two different routes, I would just define a function and call that for both routes. I wouldn't use redirect because that actually redirects the client/browser which requires them to load two pages instead of one just to save you some coding time - which seems mean :-P
So maybe:
def super_cool_logic():
# execute common code here
@app.route("/foo")
def do_foo():
# do some logic here
super_cool_logic()
return render_template("foo.html")
@app.route("/baz")
def do_baz():
if some_condition:
return render_template("baz.html")
else:
super_cool_logic()
return render_template("foo.html", messages={"main":"Condition failed on page baz"})
I feel like I'm missing something though and there's a better way to achieve what you're trying to do (I'm not really sure what you're trying to do)
You can use finds null separated output option with read to iterate over directory structures safely.
#!/bin/bash
find . -type f -print0 | while IFS= read -r -d $'\0' file;
do echo "$file" ;
done
So for your case
#!/bin/bash
find . -maxdepth 1 -type f -print0 | while IFS= read -r -d $'\0' file; do
for ((i=0; i<=3; i++)); do
./MyProgram.exe "$file" 'Logs/'"`basename "$file"`""$i"'.txt'
done
done
additionally
#!/bin/bash
while IFS= read -r -d $'\0' file; do
for ((i=0; i<=3; i++)); do
./MyProgram.exe "$file" 'Logs/'"`basename "$file"`""$i"'.txt'
done
done < <(find . -maxdepth 1 -type f -print0)
will run the while loop in the current scope of the script ( process ) and allow the output of find to be used in setting variables if needed
In general, this is a really bad way of doing things due to multipath interference. This is definitely more of an RF engineering question than a coding one.
Tl;dr, the wifi RF energy gets scattered in different directions after bouncing off walls, people, the floor etc. There's no way of telling where you are by trianglation alone, unless you're in an empty room with the wifi beacons placed in exactly the right place.
Google is able to get away with this because they essentially can map where every wifi SSID is to a GPS location when any android user (who opts in to their service) walks into range. That way, the next time a user walks by there, even without a perfect GPS signal, the google mothership can tell where you are. Typically, they'll use that in conjunction with a crappy GPS signal.
What I have seen done is a grid of Zigbee or BTLE devices. If you know where these are laid out, you can used the combined RSS to figure out relatively which ones you're closest to, and go from there.
Because Option 2 creates a new List
reference, and then creates an n
element array from the List
(option 1 perfectly sizes the output array). However, first you need to fix the off by one bug. Use <
(not <=
). Like,
String[] out = new String[n];
for(int i = 0; i < n; i++) {
out[i] = in.get(i);
}
The first parameter of Html.RadioButtonFor() should be the property name you're using, and the second parameter should be the value of that specific radio button. Then they'll have the same name attribute value and the helper will select the given radio button when/if it matches the property value.
Example:
<div class="editor-field">
<%= Html.RadioButtonFor(m => m.Gender, "M" ) %> Male
<%= Html.RadioButtonFor(m => m.Gender, "F" ) %> Female
</div>
Here's a more specific example:
I made a quick MVC project named "DeleteMeQuestion" (DeleteMe prefix so I know that I can remove it later after I forget about it).
I made the following model:
namespace DeleteMeQuestion.Models
{
public class QuizModel
{
public int ParentQuestionId { get; set; }
public int QuestionId { get; set; }
public string QuestionDisplayText { get; set; }
public List<Response> Responses { get; set; }
[Range(1,999, ErrorMessage = "Please choose a response.")]
public int SelectedResponse { get; set; }
}
public class Response
{
public int ResponseId { get; set; }
public int ChildQuestionId { get; set; }
public string ResponseDisplayText { get; set; }
}
}
There's a simple range validator in the model, just for fun. Next up, I made the following controller:
namespace DeleteMeQuestion.Controllers
{
[HandleError]
public class HomeController : Controller
{
public ActionResult Index(int? id)
{
// TODO: get question to show based on method parameter
var model = GetModel(id);
return View(model);
}
[HttpPost]
public ActionResult Index(int? id, QuizModel model)
{
if (!ModelState.IsValid)
{
var freshModel = GetModel(id);
return View(freshModel);
}
// TODO: save selected answer in database
// TODO: get next question based on selected answer (hard coded to 999 for now)
var nextQuestionId = 999;
return RedirectToAction("Index", "Home", new {id = nextQuestionId});
}
private QuizModel GetModel(int? questionId)
{
// just a stub, in lieu of a database
var model = new QuizModel
{
QuestionDisplayText = questionId.HasValue ? "And so on..." : "What is your favorite color?",
QuestionId = 1,
Responses = new List<Response>
{
new Response
{
ChildQuestionId = 2,
ResponseId = 1,
ResponseDisplayText = "Red"
},
new Response
{
ChildQuestionId = 3,
ResponseId = 2,
ResponseDisplayText = "Blue"
},
new Response
{
ChildQuestionId = 4,
ResponseId = 3,
ResponseDisplayText = "Green"
},
}
};
return model;
}
}
}
Finally, I made the following view that makes use of the model:
<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<DeleteMeQuestion.Models.QuizModel>" %>
<asp:Content ContentPlaceHolderID="TitleContent" runat="server">
Home Page
</asp:Content>
<asp:Content ContentPlaceHolderID="MainContent" runat="server">
<% using (Html.BeginForm()) { %>
<div>
<h1><%: Model.QuestionDisplayText %></h1>
<div>
<ul>
<% foreach (var item in Model.Responses) { %>
<li>
<%= Html.RadioButtonFor(m => m.SelectedResponse, item.ResponseId, new {id="Response" + item.ResponseId}) %>
<label for="Response<%: item.ResponseId %>"><%: item.ResponseDisplayText %></label>
</li>
<% } %>
</ul>
<%= Html.ValidationMessageFor(m => m.SelectedResponse) %>
</div>
<input type="submit" value="Submit" />
<% } %>
</asp:Content>
As I understand your context, you have questions with a list of available answers. Each answer will dictate the next question. Hopefully that makes sense from my model and TODO comments.
This gives you the radio buttons with the same name attribute, but different ID attributes.
I wrote a scheduler faster than cron. I have also implemented an overlapping guard. You can configure the scheduler to not start new process if previous one is still running. Take a look at https://github.com/sioux1977/scheduler/wiki
If you are using Swift, remember that println
will only print to the debug log (which appears in xCode's debug area). If you want to print to system.log, you have to use NSLog
as in the old days.
Then you can view the simulator log via its menu, Debug > Open System Log... (cmd + /)
You called an incorrect method of String class, try:
int tmpInt = 10;
String tmpStr10 = String.valueOf(tmpInt);
You can also do:
int tmpInt = 10;
String tmpStr10 = Integer.toString(tmpInt);
Create a URI like this one:
https://maps.google.com/?q=[lat],[long]
For example:
https://maps.google.com/?q=-37.866963,144.980615
or, if you are using the javascript API
map.setCenter(new GLatLng(0,0))
This, and other helpful info comes from here:
https://developers.google.com/maps/documentation/javascript/reference/?csw=1#Map
I used your idea, and found the difference and then just divided by 365 days. Worked a treat.
=MINUS(F2,TODAY())/365
Then I shifted my cell properties to not display decimals.
The best HTTP header for your client to send an access token (JWT or any other token) is the Authorization
header with the Bearer
authentication scheme.
This scheme is described by the RFC6750.
Example:
GET /resource HTTP/1.1
Host: server.example.com
Authorization: Bearer eyJhbGciOiJIUzI1NiIXVCJ9TJV...r7E20RMHrHDcEfxjoYZgeFONFh7HgQ
If you need stronger security protection, you may also consider the following IETF draft: https://tools.ietf.org/html/draft-ietf-oauth-pop-architecture. This draft seems to be a good alternative to the (abandoned?) https://tools.ietf.org/html/draft-ietf-oauth-v2-http-mac.
Note that even if this RFC and the above specifications are related to the OAuth2 Framework protocol, they can be used in any other contexts that require a token exchange between a client and a server.
Unlike the custom JWT
scheme you mention in your question, the Bearer
one is registered at the IANA.
Concerning the Basic
and Digest
authentication schemes, they are dedicated to authentication using a username and a secret (see RFC7616 and RFC7617) so not applicable in that context.
