Here is what I ended up doing to work around the error.
First, I set up the database recovery model as SIMPLE. More information here.
Then, by deleting some old files I was able to make 5GB of free space which gave the log file more space to grow.
I reran the DELETE statement sucessfully without any warning.
I thought that by running the DELETE statement the database would inmediately become smaller thus freeing space in my hard drive. But that was not true. The space freed after a DELETE statement is not returned to the operating system inmediatedly unless you run the following command:
DBCC SHRINKDATABASE (MyDb, 0);
GO
More information about that command here.
I'm using Jetbrains Rider and it was a hassle copying the results from above examples to re-execute because it seemed to wrap it all in JSON. This joins them into a single statement that was easier to run
select string_agg('drop table if exists "' || tablename || '" cascade', ';')
from pg_tables where schemaname != $$pg_catalog$$ and tableName like $$rm_%$$
This might be your problem:
height: .05em;
Chrome is a bit funky with decimals, so try a fixed-pixel height:
height: 2px;
TRIM(BOTH chr(13)||chr(10)||' ' FROM str)
Basically, you have three options:
EXPOSE
nor -p
EXPOSE
EXPOSE
and -p
1) If you specify neither EXPOSE
nor -p
, the service in the container will only be accessible from inside the container itself.
2) If you EXPOSE
a port, the service in the container is not accessible from outside Docker, but from inside other Docker containers. So this is good for inter-container communication.
3) If you EXPOSE
and -p
a port, the service in the container is accessible from anywhere, even outside Docker.
The reason why both are separated is IMHO because:
The documentation explicitly states:
The
EXPOSE
instruction exposes ports for use within links.
It also points you to how to link containers, which basically is the inter-container communication I talked about.
PS: If you do -p
, but do not EXPOSE
, Docker does an implicit EXPOSE
. This is because if a port is open to the public, it is automatically also open to other Docker containers. Hence -p
includes EXPOSE
. That's why I didn't list it above as a fourth case.
I removed Android dependencies from build path and it worked.
Edit: ignore that. I had same jar in my maven dependencies and libs folder. I removed the one at the lib folder.
Nobody actualy brought it so, the way it was made to work is animation-play-state set to paused.
With UpdateData As
(
SELECT RS_NOM,
ROW_NUMBER() OVER (ORDER BY [RS_NOM] DESC) AS RN
FROM DESTINATAIRE_TEMP
)
UPDATE DESTINATAIRE_TEMP SET CODE_DEST = RN
FROM DESTINATAIRE_TEMP
INNER JOIN UpdateData ON DESTINATAIRE_TEMP.RS_NOM = UpdateData.RS_NOM
string nonNormalized = "\r\n\n\r";
string normalized = nonNormalized.Replace("\r", "\n").Replace("\n", "\r\n");
CASE
isn't used for flow control... for this, you would need to use IF
...
But, there's a set-based solution to this problem instead of the procedural approach:
UPDATE tblEmployee
SET
InOffice = CASE WHEN @NewStatus = 'InOffice' THEN -1 ELSE InOffice END,
OutOffice = CASE WHEN @NewStatus = 'OutOffice' THEN -1 ELSE OutOffice END,
Home = CASE WHEN @NewStatus = 'Home' THEN -1 ELSE Home END
WHERE EmpID = @EmpID
Note that the ELSE
will preserves the original value if the @NewStatus
condition isn't met.
Also there is the short delegate solution:
ServicePointManager.ServerCertificateValidationCallback = delegate { return true; };
I'd say it makes it easier to reuse memory that might be used in different ways, i.e. saving memory. E.g. you'd like to do some "variant" struct that's able to save a short string as well as a number:
struct variant {
int type;
double number;
char *string;
};
In a 32 bit system this would result in at least 96 bits or 12 bytes being used for each instance of variant
.
Using an union you can reduce the size down to 64 bits or 8 bytes:
struct variant {
int type;
union {
double number;
char *string;
} value;
};
You're able to save even more if you'd like to add more different variable types etc. It might be true, that you can do similar things casting a void pointer - but the union makes it a lot more accessible as well as type safe. Such savings don't sound massive, but you're saving one third of the memory used for all instances of this struct.
Works for me
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js" type="text/javascript"></script>
<script type="text/javascript">
$("#btn").click(function() {
alert("email")
});
</script>
To make this process more robust, you could consider using the SAX parser (that way you don't have to hold the whole file in memory), read & write till the end of tree and then start appending.
Bootstrap allows you to use styling via data-content:
<select class="selectpicker">
<option data-content="<span class='label label-success'>Relish</span>">Relish</option>
</select>

It looks like changes after pandas 10.1/13.1
I upgraded from 10.1 to 13.1, before iloc is not available.
Now with 13.1, iloc[0]['label']
gets a single value array rather than a scalar.
Like this:
lastprice=stock.iloc[-1]['Close']
Output:

2014-02-26 118.2
name:Close, dtype: float64
EDIT ouch, too late... I know read your comment stating that you want to keep the feature-x changeset around, so the cloning approach here doesn't work.
I'll still let the answer here for it may help others.
If you want to completely get rid of "feature X", because, for example, it didn't work, you can clone. This is one of the method explained in the article and it does work, and it talks specifically about heads.
As far as I understand you have this and want to get rid of the "feature-x" head once and for all:
@ changeset: 7:00a7f69c8335
|\ tag: tip
| | parent: 4:31b6f976956b
| | parent: 2:0a834fa43688
| | summary: merge
| |
| | o changeset: 5:013a3e954cfd
| |/ summary: Closed branch feature-x
| |
| o changeset: 4:31b6f976956b
| | summary: Changeset2

|
o changeset: 1:1cc843e7f4b5
| summary: Changeset B
|
o changeset: 0:a9afb25eaede
summary: Changeset A
So you do this:
hg clone . ../cleanedrepo --rev 7
And you'll have the following, and you'll see that feature-x is indeed gone:
@ changeset: 5:00a7f69c8335

I may have misunderstood what you wanted but please don't mod down, I took time reproducing your use case : )
There's sweet Alert version 1 and 2. Actual version 2 works with HTML nodes.
I have a Sweet Alert 2 with a data form that looks this way:
<script>
var form = document.createElement("div");
form.innerHTML = `
<span id="tfHours">0</span> hours<br>
<input style="width:90%;" type="range" name="tfHours" value=0 step=1 min=0 max=25
onchange="window.changeHours(this.value)"
oninput="window.changeHours(this.value)"
><br>
<span id="tfMinutes">0</span> min<br>
<input style="width:60%;" type="range" name="tfMinutes" value=0 step=5 min=0 max=60
onchange="window.changeMinutes(this.value)"
oninput="window.changeMinutes(this.value)"
>`;
swal({
title: 'Request time to XXX',
text: 'Select time to send / request',
content: form,
buttons: {
cancel: "Cancel",
catch: {
text: "Create",
value: 5,
},
}
}).then((value) => {
console.log(value);
});
window.changeHours = function (value){
var tfHours = document.getElementById("tfHours");
tfHours.innerHTML = value;
}
window.changeMinutes = function (value){
var tfMinutes = document.getElementById("tfMinutes");
tfMinutes.innerHTML = value;
}
From this looks of this MSDN article, it looks like you can now bypass the MAX_PATH restriction in Windows 10 v1607 (AKA 'anniversary update') by changing a value in the registry - or via Group Policy
The ValueTuple types are built into newer frameworks:
Until you target one of those newer framework versions, you need to reference the ValueTuple package.
More details at http://blog.monstuff.com/archives/2017/03/valuetuple-availability.html
For python >= 3.6
, you can use dload:
import dload
t = dload.text(url)
For json
:
j = dload.json(url)
Install:
pip install dload
In short:
In MySQL Workbench 6.0+
With this setting you will be able to concatenate fields without getting blobs.
I think this applies to versions 5.2.22 and later and is the result of this MySQL bug.
Disclaimer: I don't know what the downside of this setting is - maybe when you are selecting BINARY
/VARBINARY
values you will see it as plain text which may be misleading and/or maybe it will hinder performance if they are large enough?
It seems like you're actually trying to extract a name vice simply find a match. If this is the case, having span indexes for your match is helpful and I'd recommend using re.finditer
. As a shortcut, you know the name
part of your regex is length 5 and the is valid
is length 9, so you can slice the matching text to extract the name.
Note - In your example, it looks like s
is string with line breaks, so that's what's assumed below.
## covert s to list of strings separated by line: s2 = s.splitlines() ## find matches by line: for i, j in enumerate(s2): matches = re.finditer("name (.*) is valid", j) ## ignore lines without a match if matches: ## loop through match group elements for k in matches: ## get text match_txt = k.group(0) ## get line span match_span = k.span(0) ## extract username my_user_name = match_txt[5:-9] ## compare with original text print(f'Extracted Username: {my_user_name} - found on line {i}') print('Match Text:', match_txt)
The server_name
docs directive is used to identify virtual hosts, they're not used to set the binding.
netstat
tells you that nginx listens on 0.0.0.0:80
which means that it will accept connections from any IP.
If you want to change the IP nginx binds on, you have to change the listen
docs rule.
So, if you want to set nginx to bind to localhost
, you'd change that to:
listen 127.0.0.1:80;
In this way, requests that are not coming from localhost are discarded (they don't even hit nginx).
You can update with a join if you only affect one table like this:
UPDATE table1
SET table1.name = table2.name
FROM table1, table2
WHERE table1.id = table2.id
AND table2.foobar ='stuff'
But you are trying to affect multiple tables with an update statement that joins on multiple tables. That is not possible.
However, updating two tables in one statement is actually possible but will need to create a View using a UNION that contains both the tables you want to update. You can then update the View which will then update the underlying tables.
But this is a really hacky parlor trick, use the transaction and multiple updates, it's much more intuitive.
You can use this solution :
function toCamelCase(str){
return str.split(' ').map(function(word,index){
// If it is the first word make sure to lowercase all the chars.
if(index == 0){
return word.toLowerCase();
}
// If it is not the first word only upper case the first char and lowercase the rest.
return word.charAt(0).toUpperCase() + word.slice(1).toLowerCase();
}).join('');
}
I recently had to figure this out for myself and ended up on a solution inspired by @Zahymaka 's answer, but solving the 2x looping of the array.
What you can do is create an array with all your keys, in the order they exist, and then loop through that.
$keys=array_keys($items);
foreach($keys as $index=>$key){
echo "position: $index".PHP_EOL."item: ".PHP_EOL;
var_dump($items[$key]);
...
}
PS: I know this is very late to the party, but since I found myself searching for this, maybe this could be helpful to someone else
Incrementing / Decrementing Operators
++
increment operator
--
decrement operator
Example Name Effect
---------------------------------------------------------------------
++$a Pre-increment Increments $a by one, then returns $a.
$a++ Post-increment Returns $a, then increments $a by one.
--$a Pre-decrement Decrements $a by one, then returns $a.
$a-- Post-decrement Returns $a, then decrements $a by one.
These can go before or after the variable.
If put before the variable, the increment/decrement operation is done to the variable first then the result is returned. If put after the variable, the variable is first returned, then the increment/decrement operation is done.
For example:
$apples = 10;
for ($i = 0; $i < 10; ++$i) {
echo 'I have ' . $apples-- . " apples. I just ate one.\n";
}
In the case above ++$i
is used, since it is faster. $i++
would have the same results.
Pre-increment is a little bit faster because it really increments the variable and after that 'returns' the result. Post-increment creates a special variable, copies there the value of the first variable and only after the first variable is used, replaces its value with second's.
However, you must use $apples--
, since first, you want to display the current number of apples, and then you want to subtract one from it.
You can also increment letters in PHP:
$i = "a";
while ($i < "c") {
echo $i++;
}
Once z
is reached aa
is next, and so on.
Note that character variables can be incremented but not decremented and even so only plain ASCII characters (a-z and A-Z) are supported.

RandomStringUtils
from Apache commons-lang might help:
RandomStringUtils.randomAlphanumeric(17).toUpperCase()
2017 update: RandomStringUtils
has been deprecated, you should now use RandomStringGenerator.
You could also just pass an EventEmitter as Input. Not quite sure if this is best practice tho...
CategoryComponent.ts:
categoryIdEvent: EventEmitter<string> = new EventEmitter<>();
- OTHER CODE -
setCategoryId(id) {
this.category.id = id;
this.categoryIdEvent.emit(this.category.id);
}
CategoryComponent.html:
<video-list *ngIf="category" [categoryId]="categoryIdEvent"></video-list>
And in VideoListComponent.ts:
@Input() categoryIdEvent: EventEmitter<string>
....
ngOnInit() {
this.categoryIdEvent.subscribe(newID => {
this.categoryId = newID;
}
}
You can install other builds but not Appstore build.
From Xcode 8.2,drag and drop the build to simulator for the installation.

.selector{
background-size: cover;
/* stretches background WITHOUT deformation so it would fill the background space,
it may crop the image if the image's dimensions are in different ratio,
than the element dimensions. */
}
Max. stretch without crop nor deformation (may not fill the background): background-size: contain;
Force absolute stretch (may cause deformation, but no crop): background-size: 100% 100%;
Absolute positioning image as a first child of the (relative positioned) parent and stretching it to the parent size.
HTML
<div class="selector">
<img src="path.extension" alt="alt text">
<!-- some other content -->
</div>
background-size: cover;
:To achieve this dynamically, you would have to use the opposite of contain method alternative (see below) and if you need to center the cropped image, you would need a JavaScript to do that dynamically - e.g. using jQuery:
$('.selector img').each(function(){
$(this).css({
"left": "50%",
"margin-left": "-"+( $(this).width()/2 )+"px",
"top": "50%",
"margin-top": "-"+( $(this).height()/2 )+"px"
});
});
Practical example:
background-size: contain;
:This one can be a bit tricky - the dimension of your background that would overflow the parent will have CSS set to 100% the other one to auto. Practical example:
.selector img{
position: absolute; top:0; left: 0;
width: 100%;
height: auto;
/* -- OR -- */
/* width: auto;
height: 100%; */
}
background-size: 100% 100%;
:.selector img{
position: absolute; top:0; left: 0;
width: 100%;
height: 100%;
}
PS: To do the equivalents of cover/contain in the "old" way completely dynamically (so you will not have to care about overflows/ratios) you would have to use javascript to detect the ratios for you and set the dimensions as described...
The following function rot(s, n)
encodes a string s
with ROT-n
encoding for any integer n
, with n
defaulting to 13. Both upper- and lowercase letters are supported. Values of n
over 26 or negative values are handled appropriately, e.g., shifting by 27 positions is equal to shifting by one position. Decoding is done with invrot(s, n)
.
import string
def rot(s, n=13):
'''Encode string s with ROT-n, i.e., by shifting all letters n positions.
When n is not supplied, ROT-13 encoding is assumed.
'''
upper = string.ascii_uppercase
lower = string.ascii_lowercase
upper_start = ord(upper[0])
lower_start = ord(lower[0])
out = ''
for letter in s:
if letter in upper:
out += chr(upper_start + (ord(letter) - upper_start + n) % 26)
elif letter in lower:
out += chr(lower_start + (ord(letter) - lower_start + n) % 26)
else:
out += letter
return(out)

When n is not supplied, ROT-13 is assumed.
'''
return(rot(s, -n))
Chrome will not render background-color, or several other styles, when printing if the background graphics setting is turned off.
This has nothing to do with css, @media, or specificity. You can probably hack your way around it, but the easiest way to get chrome to show the background-color and other graphics is to properly check this checkbox under More Settings.
function sample() {
alert("This is sample function");
}
$(function() {
$("#button").click(function() {
setTimeout(sample, 2000);
});
});
If you want to encapsulate sample()
there, wrap the whole thing in a self invoking function (function() { ... })()
.
I second jdk's answer: any public static member of any class of your application can be considered as a "global variable".
However, do note that this is an ASP.NET application, and as such, it's a multi-threaded context for your global variables. Therefore, you should use some locking mechanism when you update and/or read the data to/from these variables. Otherwise, you might get your data in a corrupted state.
you can use grid system without adding empty columns
<div class="col-xs-2 center-block" style="float:none"> ... </div>
change col-xs-2 to suit your layout.

Your test is good, but it measures only some specific situation: we have one polygon with many vertices, and long array of points to check them within polygon.
Moreover, I suppose that you're measuring not matplotlib-inside-polygon-method vs ray-method, but matplotlib-somehow-optimized-iteration vs simple-list-iteration
Let's make N independent comparisons (N pairs of point and polygon)?
# ... your code...
lenpoly = 100
polygon = [[np.sin(x)+0.5,np.cos(x)+0.5] for x in np.linspace(0,2*np.pi,lenpoly)[:-1]]
M = 10000
start_time = time()
# Ray tracing
for i in range(M):
x,y = np.random.random(), np.random.random()
inside1 = ray_tracing_method(x,y, polygon)
print "Ray Tracing Elapsed time: " + str(time()-start_time)
# Matplotlib mplPath
start_time = time()
for i in range(M):
x,y = np.random.random(), np.random.random()
inside2 = path.contains_points([[x,y]])
print "Matplotlib contains_points Elapsed time: " + str(time()-start_time)
Result:
Ray Tracing Elapsed time: 0.548588991165
Matplotlib contains_points Elapsed time: 0.103765010834
Matplotlib is still much better, but not 100 times better. Now let's try much simpler polygon...
lenpoly = 5
# ... same code
result:
Ray Tracing Elapsed time: 0.0727779865265
Matplotlib contains_points Elapsed time: 0.105288982391
One possible solution that I use is to use python3. It seems to solve many utf issues.
Sorry for the late answer, but it may help people in the future.
For example,
#!/usr/bin/env python3
import json
# your code follows
whats about using this way:
public enum HL_COLORS{
YELLOW,
ORANGE;
public int getColorValue() {
switch (this) {
case YELLOW:
return 0xffffff00;
case ORANGE:
return 0xffffa500;
default://YELLOW
return 0xffffff00;
}
}
}
there is only one method ..
you can use static method and pass the Enum as parameter like:
public enum HL_COLORS{
YELLOW,
ORANGE;
public static int getColorValue(HL_COLORS hl) {
switch (hl) {
case YELLOW:
return 0xffffff00;
case ORANGE:
return 0xffffa500;
default://YELLOW
return 0xffffff00;
}
}
Note that these two ways use less memory and more process units .. I don't say this is the best way but its just another approach.
You could always try the Synth look & feel. You provide an xml file that acts as a sort of stylesheet, along with any images you want to use. The code might look like this:
try {
SynthLookAndFeel synth = new SynthLookAndFeel();
Class aClass = MainFrame.class;
InputStream stream = aClass.getResourceAsStream("\\default.xml");
if (stream == null) {
System.err.println("Missing configuration file");
System.exit(-1);
}
synth.load(stream, aClass);
UIManager.setLookAndFeel(synth);
} catch (ParseException pe) {
System.err.println("Bad configuration file");
pe.printStackTrace();
System.exit(-2);
} catch (UnsupportedLookAndFeelException ulfe) {
System.err.println("Old JRE in use. Get a new one");
System.exit(-3);
}
From there, go on and add your JButton like you normally would. The only change is that you use the setName(string) method to identify what the button should map to in the xml file.
The xml file might look like this:
<synth>
<style id="button">
<font name="DIALOG" size="12" style="BOLD"/>
<state value="MOUSE_OVER">
<imagePainter method="buttonBackground" path="dirt.png" sourceInsets="2 2 2 2"/>
<insets top="2" botton="2" right="2" left="2"/>
</state>
<state value="ENABLED">
<imagePainter method="buttonBackground" path="dirt.png" sourceInsets="2 2 2 2"/>
<insets top="2" botton="2" right="2" left="2"/>
</state>
</style>
<bind style="button" type="name" key="dirt"/>
</synth>
The bind element there specifies what to map to (in this example, it will apply that styling to any buttons whose name property has been set to "dirt").
And a couple of useful links:

http://docs.oracle.com/javase/tutorial/uiswing/lookandfeel/synth.html
CATALINA_HOME
vs CATALINA_BASE
If you're running multiple instances, then you need both variables, otherwise only CATALINA_HOME
.
In other words: CATALINA_HOME
is required and CATALINA_BASE
is optional.
CATALINA_HOME
represents the root of your Tomcat installation.
Optionally, Tomcat may be configured for multiple instances by defining
$CATALINA_BASE
for each instance. If multiple instances are not configured,$CATALINA_BASE
is the same as$CATALINA_HOME
.
See: Apache Tomcat 7 - Introduction
Running with separate CATALINA_HOME
and CATALINA_BASE
is documented in RUNNING.txt which say:
The
CATALINA_HOME
andCATALINA_BASE
environment variables are used to specify the location of Apache Tomcat and the location of its active configuration, respectively.You cannot configure
CATALINA_HOME
andCATALINA_BASE
variables in thesetenv
script, because they are used to find that file.
For example:
(4.1) Tomcat can be started by executing one of the following commands:
%CATALINA_HOME%\bin\startup.bat (Windows) $CATALINA_HOME/bin/startup.sh (Unix)
or
%CATALINA_HOME%\bin\catalina.bat start (Windows) $CATALINA_HOME/bin/catalina.sh start (Unix)
In many circumstances, it is desirable to have a single copy of a Tomcat binary distribution shared among multiple users on the same server. To make this possible, you can set the
CATALINA_BASE
environment variable to the directory that contains the files for your 'personal' Tomcat instance.When running with a separate
CATALINA_HOME
andCATALINA_BASE
, the files and directories are split as following:In
CATALINA_BASE
:
bin
- Only: setenv.sh (*nix) or setenv.bat (Windows), tomcat-juli.jarconf
- Server configuration files (including server.xml)lib
- Libraries and classes, as explained belowlogs
- Log and output fileswebapps
- Automatically loaded web applicationswork
- Temporary working directories for web applicationstemp
- Directory used by the JVM for temporary files>In
CATALINA_HOME
:
bin
- Startup and shutdown scriptslib
- Libraries and classes, as explained belowendorsed
- Libraries that override standard "Endorsed Standards". By default it's absent.
The easiest way to check what's your CATALINA_BASE
and CATALINA_HOME
is by running startup.sh
, for example:
$ /usr/share/tomcat7/bin/startup.sh
Using CATALINA_BASE: /usr/share/tomcat7
Using CATALINA_HOME: /usr/share/tomcat7
You may also check where the Tomcat files are installed, by dpkg
tool as below (Debian/Ubuntu):
dpkg -L tomcat7-common
How reliable is your format? If the seperator is always exactly ': ', the following works. If not, a comparatively simple regex should do the job.
As long as you're working with fairly simple variable types, Python's eval function makes persisting variables to files surprisingly easy.
(The below gives you a dictionary, btw, which you mentioned was one of your prefered solutions).
def read_config(filename):
f = open(filename)
config_dict = {}
for lines in f:

The error is due to corrupt or missing SSL chain certificate files in the PKI directory. You’ll need to make sure the files ca-bundle, following steps: In your console/terminal:
mkdir /usr/src/ca-certificates && cd /usr/src/ca-certificates
Enter this site: https://rpmfind.net/linux/rpm2html/search.php?query=ca-certificates , get your ca-certificate, for yout SO, for example: ftp://rpmfind.net/linux/fedora/linux/updates/24/x86_64/c/ca-certificates-2016.2.8-1.0.fc24.noarch.rpm << CentOS. Copy url of download and paste in url: wget your_url_donwload_ca-ceritificated.rpm now, install yout rpm:
rpm2cpio your_url_donwload_ca-ceritificated.rpm | cpio -idmv
now restart your service: my example this command:
sudo service2 httpd restart
very great good look
Just putting my 2 cents here.
Given the following class:
class Foo
{
private $data;
public function __construct(array $data)
{
$this->data = $data;
}
public function __get($name)
{
return $data[$name];
}
public function __isset($name)
{
return array_key_exists($name, $this->data);
}
}
the following will happen:
$foo = new Foo(['key' => 'value', 'bar' => null]);
var_dump(property_exists($foo, 'key')); // false
var_dump(isset($foo->key)); // true
var_dump(property_exists($foo, 'bar')); // false
var_dump(isset($foo->bar)); // true, although $data['bar'] == null
Hope this will help anyone
coll.Reverse().Take(N).Reverse().ToList();
public static IEnumerable<T> TakeLast<T>(this IEnumerable<T> coll, int N)
{
return coll.Reverse().Take(N).Reverse();
}
UPDATE: To address clintp's problem: a) Using the TakeLast() method I defined above solves the problem, but if you really want the do it without the extra method, then you just have to recognize that while Enumerable.Reverse() can be used as an extension method, you aren't required to use it that way:
List<string> mystring = new List<string>() { "one", "two", "three" };
mystring = Enumerable.Reverse(mystring).Take(2).Reverse().ToList();
You will certainly be able to do that using WITH clause, or use analytic functions available in Oracle SQL.
With some effort you'd be able to get anything out of them in terms of cycles as in ordinary procedural languages. Both approaches are pretty powerful compared to ordinary SQL.

It requires some effort though. Don't be afraid to post a concrete example.
Using simple pseudo table DUAL helps too.
There is no 100% solution to delete browser cookies.
The problem is that cookies are uniquely identified by not just by their key "name" but also their "domain" and "path".
Without knowing the "domain" and "path" of a cookie, you cannot reliably delete it. This information is not available through JavaScript's document.cookie
. It's not available through the HTTP Cookie header either!
However, if you know the name, path and domain of a cookie, then you can clear it by setting an empty cookie with an expiry date in the past, for example:
function clearCookie(name, domain, path){
var domain = domain || document.domain;
var path = path || "/";
document.cookie = name + "=; expires=" + +new Date + "; domain=" + domain + "; path=" + path;
};

I had the same requirements as you but couldn't find a suitable database. nStore was promising but the API was not nearly complete enough and not very coherent.
That's why I made NeDB, which a dependency-less embedded database for Node.js projects. You can use it with a simple require()
, it is persistent, and its API is the most commonly used subset of the very well-known MongoDB API.
The other answer didn't work for me (on Windows 7). But this worked:
telnet localhost 5554
kill
I pass around a simple Hashtable object with a single result member to avoid the return craziness as I also want to output to the console. It acts through pass by reference.
function sample-loop($returnObj) {
for($i = 0; $i -lt 10; $i++) {
Write-Host "loop counter: $i"
$returnObj.result++
}
}
function main-sample() {
$countObj = @{ result = 0 }
sample-loop -returnObj $countObj
Write-Host "_____________"
Write-Host "Total = " ($countObj.result)
}
main-sample

Twisted can help you with what you are doing, check out their documentation, there are plenty of examples. Also it is a mature product with a big developer/user community behind it.
Zonble has already provided an excellent answer.
I thought it may be useful to include a short code snippet for adding a UIView
to the tableview cell that will present as the selected background view.
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
UIView *selectionColor = [[UIView alloc] init];
selectionColor.backgroundColor = [UIColor colorWithRed:(245/255.0) green:(245/255.0) blue:(245/255.0) alpha:1];
cell.selectedBackgroundView = selectionColor;
UITableViewCell
selectedBackgroundView
to be the UIView
that I created with my chosen background colourThis worked well for me. Thanks for the tip Zonble.
Are you trying to find some work around getting xpath in IE?
There are many add-ons for other browsers like xpather for Chrome or xpather, xpath-checker and firebug for FireFox that will give you the xpath of an element in a second. But sadly there is no add-on or tool available that will do this for IE. For most cases you can get the xpath of the elements that fall in your script using the above tools in Firefox and tweak them a little (if required) to make them work in IE.
But if you are testing an application that will work only in IE or the specific scenario or page that has this element will open-up/play-out only in IE then you cannot use any of the above mention tools to find the XPATH. Well the only thing that works in this case is the Bookmarklets that were coded just for this purpose. Bookmarklets are JavaScript code that you will add in IE as bookmarks and later use to get the XPATH of the element you desire. Using these you can get the XPATH as easily as you get using xpather or any other firefox addon.
STEPS TO INSTALL BOOKMARKLETS
1)Open IE
2)Type about:blank in the address bar and hit enter
3)From Favorites main menu select ---> Add favorites
4) In the Add a favorite popup window enter name GetXPATH1.
5)Click add button in the add a favorite popup window.
6)Open the Favorites menu and right click the newly added favorite and select properties option.
7)GetXPATH1 Properties will open up. Select the web Document Tab.
8)Enter the following in the URL field.
javascript:function getNode(node){var nodeExpr=node.tagName;if(!nodeExpr)return null;if(node.id!=''){nodeExpr+="[@id='"+node.id+"']";return "/"+nodeExpr;}var rank=1;var ps=node.previousSibling;while(ps){if(ps.tagName==node.tagName){rank++;}ps=ps.previousSibling;}if(rank>1){nodeExpr+='['+rank+']';}else{var ns=node.nextSibling;while(ns){if(ns.tagName==node.tagName){nodeExpr+='[1]';break;}ns=ns.nextSibling;}}return nodeExpr;}
9)Click Ok. Click YES on the popup alert.
10)Add another favorite by following steps 3 to 5, Name this favorite GetXPATH2 (step4)
11)Repeat steps 6 and 7 for GetXPATH2 that you just created.
12)Enter the following in the URL field for GetXPATH2
javascript:function o__o(){var currentNode=document.selection.createRange().parentElement();var path=[];while(currentNode){var pe=getNode(currentNode);if(pe){path.push(pe);if(pe.indexOf('@id')!=-1)break;}currentNode=currentNode.parentNode;}var xpath="/"+path.reverse().join('/');clipboardData.setData("Text", xpath);}o__o();
13)Repeat Step 9.
You are all done!!
Now to get the XPATH of elements just select the element with your mouse. This would involve clicking the left mouse button just before the element (link, button, image, checkbox, text etc) begins and dragging it till the element ends. Once you do this first select the favorite GetXPATH1 from the favorites menu and then select the second favorite GetXPATH2. At this point you will get a confirmation, hit allow access button. Now open up a notepad file, right click and select paste option. This will give you the XPATH of the element you seek.
While ASP.NET MVC will allow you to have two actions with the same name, .NET won't allow you to have two methods with the same signature - i.e. the same name and parameters.
You will need to name the methods differently use the ActionName attribute to tell ASP.NET MVC that they're actually the same action.
That said, if you're talking about a GET and a POST, this problem will likely go away, as the POST action will take more parameters than the GET and therefore be distinguishable.
So, you need either:
[HttpGet]
public ActionResult ActionName() {...}
[HttpPost, ActionName("ActionName")]
public ActionResult ActionNamePost() {...}
Or,
[HttpGet]
public ActionResult ActionName() {...}
[HttpPost]
public ActionResult ActionName(string aParameter) {...}
Obligatory answer in Swift : NSIndexPath(forRow:row, inSection: section)
You will notice that NSIndexPath.indexPathForRow(row, inSection: section)
is not available in swift and you must use the first method to construct the indexPath.
If script execution order is not the issue, another possible cause of the problem is that the element is not being selected properly:
getElementById
requires the passed string to be the ID verbatim, and nothing else. If you prefix the passed string with a #
, and the ID does not start with a #
, nothing will be selected:
<div id="foo"></div>
// Error, selected element will be null:
document.getElementById('#foo')
// Fix:
document.getElementById('foo')
Similarly, for getElementsByClassName
, don't prefix the passed string with a .
:
<div class="bar"></div>
// Error, selected element will be undefined:
document.getElementsByClassName('.bar')[0]
// Fix:
document.getElementsByClassName('bar')[0]
With querySelector, querySelectorAll, and jQuery, to match an element with a particular class name, put a .
directly before the class. Similarly, to match an element with a particular ID, put a #
directly before the ID:
<div class="baz"></div>
// Error, selected element will be null:
document.querySelector('baz')
$('baz')
// Fix:
document.querySelector('.baz')
$('.baz')
The rules here are, in most cases, identical to those for CSS selectors, and can be seen in detail here.
To match an element which has two or more attributes (like two class names, or a class name and a data-
attribute), put the selectors for each attribute next to each other in the selector string, without a space separating them (because a space indicates the descendant selector). For example, to select:
<div class="foo bar"></div>
use the query string .foo.bar
. To select
<div class="foo" data-bar="someData"></div>
use the query string .foo[data-bar="someData"]
. To select the <span>
below:
<div class="parent">
<span data-username="bob"></span>
</div>
use div.parent > span[data-username="bob"]
.
Capitalization and spelling does matter for all of the above. If the capitalization is different, or the spelling is different, the element will not be selected:
<div class="result"></div>
// Error, selected element will be null:
document.querySelector('.results')
$('.Result')
// Fix:
document.querySelector('.result')
$('.result')
You also need to make sure the methods have the proper capitalization and spelling. Use one of:
$(selector)
document.querySelector
document.querySelectorAll
document.getElementsByClassName
document.getElementsByTagName
document.getElementById
Any other spelling or capitalization will not work. For example, document.getElementByClassName
will throw an error.
Make sure you pass a string to these selector methods. If you pass something that isn't a string to querySelector
, getElementById
, etc, it almost certainly won't work.
If the HTML attributes on elements you want to select are surrounded by quotes, they must be plain straight quotes (either single or double); curly quotes like ‘
or ”
will not work if you're trying to select by ID, class, or attribute.
Max has the best solution for when you always want to start both projects, but you can also right click a project and choose menu Debug ? Start New Instance.
This is an option when you only occasionally need to start the second project or when you need to delay the start of the second project (maybe the server needs to get up and running before the client tries to connect, or something).
I realize I am biased as an old C programmer, but there are times when the various Python conventions make things hard to follow. I find the indent convention a bit of an annoyance at times.
Sometimes, clarity of when a statement or block ends is very useful. Standard C code will often read something like this:
for(i=0; i<100; i++) {
do something here;
do another thing here;
}
continue doing things;
where you use the whitespace for a lot of clarity - and it is easy to see where the loop ends.
Python does let you terminate with an (optional) semicolon. As noted above, that does NOT mean that there is a statement to execute followed by a 'null' statement. SO, for example,
print(x);
print(y);
Is the same as
print(x)
print(y)
If you believe that the first one has a null statement at the end of each line, try - as suggested - doing this:
print(x);;
It will throw a syntax error.
Personally, I find the semicolon to make code more readable when you have lots of nesting and functions with many arguments and/or long-named args. So, to my eye, this is a lot clearer than other choices:
if some_boolean_is_true:
call_function(
long_named_arg_1,
long_named_arg_2,
long_named_arg_3,
long_named_arg_4
);
since, to me, it lets you know that last ')' ends some 'block' that ran over many lines.
I personally think there is much to much made of PEP style guidelines, IDEs that enforce them, and the belief there is 'only one Pythonic way to do things'. If you believe the latter, go look at how to format numbers: as of now, Python supports four different ways to do it.
I am sure I will be flamed by some diehards, but the compiler/interpreter doesn't care if the arguments have long or short names, and - but for the indentation convention in Python - doesn't care about whitespace. The biggest problem with code is giving clarity to another human (and even yourself after months of work) to understand what is going on, where things start and end, etc.
Please try this - Create a directory 'config' in your lumen setup, and then create app.php file inside this 'config' dir. it will look like this -
<?php return ['app.timezone' => 'America/Los_Angeles'];
Then you can access its value anywhere like this -
$value = config('app.timezone');
If it doesn't work, you can add this lines in routes.php
date_default_timezone_set('America/Los_Angeles');
This worked for me!
For all practical purposes, the first thing you should be worried about is CHANGING YOUR PASSWORDS! It's not clear from your question whether your git repository is entirely local or whether you have a remote repository elsewhere yet; if it is remote and not secured from others you have a problem. If anyone has cloned that repository before you fix this, they'll have a copy of your passwords on their local machine, and there's no way you can force them to update to your "fixed" version with it gone from history. The only safe thing you can do is change your password to something else everywhere you've used it.
With that out of the way, here's how to fix it. GitHub answered exactly that question as an FAQ:
Note for Windows users: use double quotes (") instead of singles in this command
git filter-branch --index-filter \
'git update-index --remove PATH-TO-YOUR-FILE-WITH-SENSITIVE-DATA' <introduction-revision-sha1>..HEAD
git push --force --verbose --dry-run
git push --force
Update 2019:
This is the current code from the FAQ:
git filter-branch --force --index-filter \
"git rm --cached --ignore-unmatch PATH-TO-YOUR-FILE-WITH-SENSITIVE-DATA" \
--prune-empty --tag-name-filter cat -- --all
git push --force --verbose --dry-run
git push --force
Keep in mind that once you've pushed this code to a remote repository like GitHub and others have cloned that remote repository, you're now in a situation where you're rewriting history. When others try pull down your latest changes after this, they'll get a message indicating that the changes can't be applied because it's not a fast-forward.
To fix this, they'll have to either delete their existing repository and re-clone it, or follow the instructions under "RECOVERING FROM UPSTREAM REBASE" in the git-rebase manpage.
Tip: Execute git rebase --interactive
In the future, if you accidentally commit some changes with sensitive information but you notice before pushing to a remote repository, there are some easier fixes. If you last commit is the one to add the sensitive information, you can simply remove the sensitive information, then run:
git commit -a --amend
That will amend the previous commit with any new changes you've made, including entire file removals done with a git rm
. If the changes are further back in history but still not pushed to a remote repository, you can do an interactive rebase:
git rebase -i origin/master
That opens an editor with the commits you've made since your last common ancestor with the remote repository. Change "pick" to "edit" on any lines representing a commit with sensitive information, and save and quit. Git will walk through the changes, and leave you at a spot where you can:
$EDITOR file-to-fix
git commit -a --amend
git rebase --continue
For each change with sensitive information. Eventually, you'll end up back on your branch, and you can safely push the new changes.
Veverke mentioned that it is possible to disable generation of binding redirects by setting AutoGEneratedBindingRedirects to false. Not sure if it's a new thing since this question was posted, but there is an "Skip applying binding redirects" option in Tools/Options/Nuget Packet Manager, which can be toggled. By default it is off, meaning the redirects will be applied. However if you do this, you will have to manage any necessary binding redirects manually.
cout
is in std namespace, you shall use std::cout
in your code.
And you shall not add using namespace std;
in your header file, it's bad to mix your code with std namespace, especially don't add it in header file.
Often you will want to have a definition of an interface without having to ship the entire code. For example, if you have a shared library, you would ship a header file with it which defines all the functions and symbols used in the shared library. Without header files, you would need to ship the source.
Within a single project, header files are used, IMHO, for at least two purposes:
innerHTML is not standard and may not work in some browsers. I have used html() in all browsers with no problem.
Yes there is a problem with Click event handler (klik) - First argument must be an object type and second must be EventArgs.
public void klik(object sender, EventArgs e) {
//
}
If you want to paint on a form or control then use CreateGraphics
method.
public void klik(object sender, EventArgs e) {
Bitmap c = this.DrawMandel();
Graphics gr = CreateGraphics(); // Graphics gr=(sender as Button).CreateGraphics();
gr.DrawImage(b, 150, 200);
}
The problem was that the wrong hamcrest.Matcher
, not hamcrest.MatcherAssert
, class was being used. That was being pulled in from a junit-4.8 dependency one of my dependencies was specifying.
To see what dependencies (and versions) are included from what source while testing, run:
mvn dependency:tree -Dscope=test
Type in pip3 install yaml or like Connor pip3 install strictyaml
In Visual Studio 2015 Update3 I have this feature.
Just by highlighting properties and then press Ctrl + . and then press Generate Constructor.
For example, if you've highlighted two properties it will suggest you to create a constructor with two parameters and if you've selected three it will suggest one with three parameters and so on.
It also works with Visual Studio 2017 and 2019.
The correct thing to do here is to store it as uniqueidentifier
- this is then fully indexable, etc. at the database. The next-best option would be a binary(16)
column: standard GUIDs are exactly 16 bytes in length.
If you must store it as a string, the length really comes down to how you choose to encode it. As hex (AKA base-16 encoding) without hyphens it would be 32 characters (two hex digits per byte), so char(32)
.
However, you might want to store the hyphens. If you are short on space, but your database doesn't support blobs / guids natively, you could use Base64 encoding and remove the ==
padding suffix; that gives you 22 characters, so char(22)
. There is no need to use Unicode, and no need for variable-length - so nvarchar(max)
would be a bad choice, for example.
I would suggest to use jquery for this type of requirement . Give this a try
<div id="commentList"></div>
<div id="addCommentContainer">
<p>Add a Comment</p> <br/> <br/>
<form id="addCommentForm" method="post" action="">
<div>
Your Name <br/>
<input type="text" name="name" id="name" />
<br/> <br/>
Comment Body <br/>
<textarea name="body" id="body" cols="20" rows="5"></textarea>
<input type="submit" id="submit" value="Submit" />
</div>
</form>
</div>?
$(document).ready(function(){
/* The following code is executed once the DOM is loaded */
/* This flag will prevent multiple comment submits: */
var working = false;
$("#submit").click(function(){
$.ajax({
type: 'POST',
url: "mysubmitpage.php",
data: $('#addCommentForm').serialize(),
success: function(response) {
alert("Submitted comment");
$("#commentList").append("Name:" + $("#name").val() + "<br/>comment:" + $("#body").val());
},
error: function() {
//$("#commentList").append($("#name").val() + "<br/>" + $("#body").val());
alert("There was an error submitting comment");
}
});
});
});?
If your Rails version is between > 3.1.0
and < 4
, place your fonts in any of the these folders:
app/assets/fonts
lib/assets/fonts
vendor/assets/fonts
For Rails versions > 4
, you must place your fonts in the app/assets/fonts
folder.
Note: To place fonts outside of these designated folders, use the following configuration:
config.assets.precompile << /\.(?:svg|eot|woff|ttf)\z/
For Rails versions > 4.2
, it is recommended to add this configuration to config/initializers/assets.rb
.
However, you can also add it to either config/application.rb
, or to config/production.rb
Declare your font in your CSS file:
@font-face {
font-family: 'Icomoon';
src:url('icomoon.eot');
src:url('icomoon.eot?#iefix') format('embedded-opentype'),
url('icomoon.svg#icomoon') format('svg'),
url('icomoon.woff') format('woff'),
url('icomoon.ttf') format('truetype');
font-weight: normal;
font-style: normal;
}
Make sure your font is named exactly the same as in the URL portion of the declaration. Capital letters and punctuation marks matter. In this case, the font should have the name icomoon
.
If you are using Sass or Less with Rails > 3.1.0
(your CSS file has .scss
or .less
extension), then change the url(...)
in the font declaration to font-url(...)
.
Otherwise, your CSS file should have the extension .css.erb
, and the font declaration should be url('<%= asset_path(...) %>')
.
If you are using Rails > 3.2.1
, you can use font_path(...)
instead of asset_path(...)
. This helper does exactly the same thing but it's more clear.
Finally, use your font in your CSS like you declared it in the font-family
part. If it was declared capitalized, you can use it like this:
font-family: 'Icomoon';
Uses of Reflection
Reflection is commonly used by programs which require the ability to examine or modify the runtime behavior of applications running in the Java virtual machine. This is a relatively advanced feature and should be used only by developers who have a strong grasp of the fundamentals of the language. With that caveat in mind, reflection is a powerful technique and can enable applications to perform operations which would otherwise be impossible.
Extensibility Features
An application may make use of external, user-defined classes by creating instances of extensibility objects using their fully-qualified names. Class Browsers and Visual Development Environments A class browser needs to be able to enumerate the members of classes. Visual development environments can benefit from making use of type information available in reflection to aid the developer in writing correct code. Debuggers and Test Tools Debuggers need to be able to examine private members in classes. Test harnesses can make use of reflection to systematically call a discoverable set APIs defined on a class, to ensure a high level of code coverage in a test suite.
Drawbacks of Reflection
Reflection is powerful, but should not be used indiscriminately. If it is possible to perform an operation without using reflection, then it is preferable to avoid using it. The following concerns should be kept in mind when accessing code via reflection.
Because reflection involves types that are dynamically resolved, certain Java virtual machine optimizations cannot be performed. Consequently, reflective operations have slower performance than their non-reflective counterparts and should be avoided in sections of code which are called frequently in performance-sensitive applications.
Reflection requires a runtime permission which may not be present when running under a security manager. This is in an important consideration for code which has to run in a restricted security context, such as in an Applet.
Since reflection allows code to perform operations that would be illegal in non-reflective code, such as accessing private fields and methods, the use of reflection can result in unexpected side-effects, which may render code dysfunctional and may destroy portability. Reflective code breaks abstractions and therefore may change behavior with upgrades of the platform.

You can not return anonymous types directly, but you can loop them through your generic method. So do most of LINQ extension methods. There is no magic in there, while it looks like it they would return anonymous types. If parameter is anonymous result can also be anonymous.
var result = Repeat(new { Name = "Foo Bar", Age = 100 }, 10);
private static IEnumerable<TResult> Repeat<TResult>(TResult element, int count)
{
for(int i=0; i<count; i++)
{
yield return element;
}
}
Below an example based on code from original question:
var result = GetDogsWithBreedNames((Name, BreedName) => new {Name, BreedName });
public static IQueryable<TResult> GetDogsWithBreedNames<TResult>(Func<object, object, TResult> creator)
{
var db = new DogDataContext(ConnectString);
var result = from d in db.Dogs
join b in db.Breeds on d.BreedId equals b.BreedId
select creator(d.Name, b.BreedName);
return result;
}
Well! As I saw my question now, I realized that I didn't want to mention fixed margin value because of the dynamic height of header.
Here is what I have been using for such scenarios.
Calculate the header height using jQuery and apply that as a top margin value.
var divHeight = $('#header-wrap').height();
$('#container').css('margin-top', divHeight+'px');
To change bottom line color, you can use this in your app theme:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
<item name="colorControlNormal">#c5c5c5</item>
<item name="colorControlActivated">#ffe100</item>
<item name="colorControlHighlight">#ffe100</item>
</style>
To change floating label color write following theme:
<style name="TextAppearence.App.TextInputLayout" parent="@android:style/TextAppearance">
<item name="android:textColor">#4ffd04[![enter image description here][1]][1]</item>
</style>
and use this theme in your layout:
<android.support.design.widget.TextInputLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="20dp"
app:hintTextAppearance="@style/TextAppearence.App.TextInputLayout">
<EditText
android:id="@+id/edtTxtFirstName_CompleteProfileOneActivity"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:capitalize="characters"
android:hint="User Name"
android:imeOptions="actionNext"
android:inputType="text"
android:singleLine="true"
android:textColor="@android:color/white" />
</android.support.design.widget.TextInputLayout>
I have used in this way. Its Working fine!
$rules = [
'password' => [
'required',
'string',
'min:6',
'max:12', // must be at least 8 characters in length
],
'confirm_password' => 'required|same:password|min:6'
];
I had the same problem with .c files that contained functions (not main()
of my program). For example, my header files were "fact.h" and "fact.c", and my main program was "main.c" so my commands were like this:
E:\proj> gcc -c fact.c
Now I had an object file of fact.c (fact.o). after that:
E:\proj>gcc -o prog.exe fact.o main.c
Then my program (prog.exe) was ready to use and worked properly. I think that -c
after gcc
was important, because it makes object files that can attach to make the program we need. Without using -c
, gcc ties to find main in your program and when it doesn't find it, it gives you this error.
If it is a directory you own, grant yourself access to it:
chmod u+rx,go-w openfire
That grants you permission to use the directory and the files in it (x
) and to list the files that are in it (r
); it also denies group and others write permission on the directory, which is usually correct (though sometimes you may want to allow group to create files in your directory - but consider using the sticky bit on the directory if you do).
If it is someone else's directory, you'll probably need some help from the owner to change the permissions so that you can access it (or you'll need help from root
to change the permissions for you).
MSVC 2010 solution, since it doesn't support std::initializer_list<>
for vectors but it does support std::end
const char *args[] = {"hello", "world!"};
std::vector<std::string> v(args, std::end(args));

Work this end (XP).
Create a new file, call it test.vbs. Put this in it.
WScript.Sleep 1000
MsgBox "TEST"
Run it, notice the delay before the message box is shown.
Note, the number is in Milliseconds, so 1000 is 1 second.
The simplest way is to generate a random nuber between 0-1 then strech it by multiplying, and shifting it.
So yo would multiply by (x-y) so the result is in the range of 0 to x-y,
Then add x and you get the random number between x and y.
To get a five multiplier use rounding. If this is unclear let me know and I'll add code snippets.
Starting from C# 2.0, you can use the nullable generic type Nullable, and in C# there is a shorthand notation the type followed by ?
e.g.
private void Example(int? arg1, int? arg2)
{
if(arg1 == null)
{
//do something
}
if(arg2 == null)
{
//do something else
}
}
Perhaps GitHub's support for deploy keys is what you're looking for? To quote that page:
When should I use a deploy key?
Simple, when you have a server that needs pull access to a single private repo. This key is attached directly to the repository instead of to a personal user account.
If that's what you're already trying and it doesn't work, you might want to update your question with more details of the URLs being used, the names and location of the key files, etc.
Now for the technical part: How to use your SSH key with Jenkins?
If you have, say, a jenkins
unix user, you can store your deploy key in ~/.ssh/id_rsa
. When Jenkins tries to clone the repo via ssh, it will try to use that key.
In some setups, you cannot run Jenkins as an own user account, and possibly also cannot use the default ssh key location ~/.ssh/id_rsa
. In such cases, you can create a key in a different location, e.g. ~/.ssh/deploy_key
, and configure ssh
to use that with an entry in ~/.ssh/config
:
Host github-deploy-myproject
HostName github.com
User git
IdentityFile ~/.ssh/deploy_key
IdentitiesOnly yes
Because all you authenticate to all Github repositories using [email protected]
and you don't want the above key to be used for all your connections to Github, we created a host alias github-deploy-myproject. Your clone URL now becomes
git clone github-deploy-myproject:myuser/myproject
and that is also what you put as repository URL into Jenkins.
(Note that you must not put ssh:// in front in order for this to work.)
Assuming that you only want to read a single line, then use LINE_MAX
, which is defined in <limits.h>
:
#include <stdio.h>
#include <limits.h>
...
char line[LINE_MAX];
...
if (fgets(line, LINE_MAX, stdin) != NULL) {
...
}
...
You can also specify context location relatively to current classpath, which may be preferable
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:applicationContext*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
Here's the mysql reference for cursors. So I'm guessing it's something like this:
DECLARE done INT DEFAULT 0;
DECLARE products_id INT;
DECLARE result varchar(4000);
DECLARE cur1 CURSOR FOR SELECT products_id FROM sets_products WHERE set_id = 1;
DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;
OPEN cur1;
REPEAT
FETCH cur1 INTO products_id;
IF NOT done THEN
CALL generate_parameter_list(@product_id, @result);
SET param = param + "," + result; -- not sure on this syntax
END IF;
UNTIL done END REPEAT;
CLOSE cur1;
-- now trim off the trailing , if desired
this should work out,
kable(dt) %>%
kable_styling("striped") %>%
add_header_above(c(" " = 1, "Group 1" = 2, "Group 2" = 2, "Group 3" = 2))
#OR
kable(dt) %>%
kable_styling(c("striped", "bordered")) %>%
add_header_above(c(" ", "Group 1" = 2, "Group 2" = 2, "Group 3" = 2)) %>%
add_header_above(c(" ", "Group 4" = 4, "Group 5" = 2)) %>%
add_header_above(c(" ", "Group 6" = 6))

I am facing small trouble in returning a value from callback function in Node.js
This is not a "small trouble", it is actually impossible to "return" a value in the traditional sense from an asynchronous function.
Since you cannot "return the value" you must call the function that will need the value once you have it. @display_name already answered your question, but I just wanted to point out that the return in doCall is not returning the value in the traditional way. You could write doCall as follow:
function doCall(urlToCall, callback) {
urllib.request(urlToCall, { wd: 'nodejs' }, function (err, data, response) {
var statusCode = response.statusCode;
finalData = getResponseJson(statusCode, data.toString());
// call the function that needs the value
callback(finalData);
// we are done
return;
});
}
Line callback(finalData);
is what calls the function that needs the value that you got from the async function. But be aware that the return statement is used to indicate that the function ends here, but it does not mean that the value is returned to the caller (the caller already moved on.)
The first proposed solution is pretty close. If you use stop() instead of interrupt() it even kills runaway threads, that run endlessly in a groovy system script. This will kill any build, that runs for a job. Here is the code:
Thread.getAllStackTraces().keySet().each() {
if (it.name.contains('YOUR JOBNAME')) {
println "Stopping $it.name"
it.stop()
}
}
A tiny update for @Terry Young answer, i.e. add IE 10+ support
if (window.navigator.msSaveOrOpenBlob) {
// IE 10+
var blob = new Blob([decodeURIComponent(encodeURI(csvString))], {
type: 'text/csv;charset=' + document.characterSet
});
window.navigator.msSaveBlob(blob, filename);
} else {
// actual real browsers
//Data URI
csvData = 'data:application/csv;charset=utf-8,' + encodeURIComponent(csvData);
$(this).attr({
'download': filename,
'href': csvData,
'target': '_blank'
});
}
Assuming you're in the Object Explorer Details (F7) showing the list of Stored Procedures, click the Filters button and enter the name (or partial name).
The easiest way is:
var oldstr="Angular isn't easy";
var newstr=oldstr.toString().replace("isn't","is");
Kindly ensure, the other columns are not constrained to accept Not null
values, hence while creating columns in table just ignore "Not Null" syntax. eg
Create Table Table_Name(
col1 DataType,
col2 DataType);
You can then insert multiple row values in any of the columns you want to. For instance:
Insert Into TableName(columnname)
values
(x),
(y),
(z);
and so on…
Hope this helps.
The -f
is actually required because of the rebase. Whenever you do a rebase you would need to do a force push because the remote branch cannot be fast-forwarded to your commit. You'd always want to make sure that you do a pull before pushing, but if you don't like to force push to master or dev for that matter, you can create a new branch to push to and then merge or make a PR.
I'm using this on my site (for example here), but I'm using some extra stuff to do lazy loading, meaning extracting the code isn't as straightforward as I would like it to be for putting it in a fiddle.
Also, my templating engine is smarty, but I'm sure you get the idea.
The meat...
Updating the indicators:
<ol class="carousel-indicators">
{assign var='walker' value=0}
{foreach from=$item["imagearray"] key="key" item="value"}
<li data-target="#myCarousel" data-slide-to="{$walker}"{if $walker == 0} class="active"{/if}>
<img src='http://farm{$value["farm"]}.static.flickr.com/{$value["server"]}/{$value["id"]}_{$value["secret"]}_s.jpg'>
</li>
{assign var='walker' value=1 + $walker}
{/foreach}
</ol>
Changing the CSS related to the indicators:
.carousel-indicators {
bottom:-50px;
height: 36px;
overflow-x: hidden;
white-space: nowrap;
}
.carousel-indicators li {
text-indent: 0;
width: 34px !important;
height: 34px !important;
border-radius: 0;
}
.carousel-indicators li img {
width: 32px;
height: 32px;
opacity: 0.5;
}
.carousel-indicators li:hover img, .carousel-indicators li.active img {
opacity: 1;
}
.carousel-indicators .active {
border-color: #337ab7;
}
When the carousel has slid, update the list of thumbnails:
$('#myCarousel').on('slid.bs.carousel', function() {
var widthEstimate = -1 * $(".carousel-indicators li:first").position().left + $(".carousel-indicators li:last").position().left + $(".carousel-indicators li:last").width();
var newIndicatorPosition = $(".carousel-indicators li.active").position().left + $(".carousel-indicators li.active").width() / 2;
var toScroll = newIndicatorPosition + indicatorPosition;
var adjustedScroll = toScroll - ($(".carousel-indicators").width() / 2);
if (adjustedScroll < 0)
adjustedScroll = 0;
if (adjustedScroll > widthEstimate - $(".carousel-indicators").width())
adjustedScroll = widthEstimate - $(".carousel-indicators").width();
$('.carousel-indicators').animate({ scrollLeft: adjustedScroll }, 800);
indicatorPosition = adjustedScroll;
});
And, when your page loads, set the initial scroll position of the thumbnails:
var indicatorPosition = 0;
What is that BasePagerAdapter
? You should use one of the standard pager adapters -- either FragmentPagerAdapter
or FragmentStatePagerAdapter
, depending on whether you want Fragments that are no longer needed by the ViewPager
to either be kept around (the former) or have their state saved (the latter) and re-created if needed again.
Sample code for using ViewPager
can be found here
It is true that the management of fragments in a view pager across activity instances is a little complicated, because the FragmentManager
in the framework takes care of saving the state and restoring any active fragments that the pager has made. All this really means is that the adapter when initializing needs to make sure it re-connects with whatever restored fragments there are. You can look at the code for FragmentPagerAdapter
or FragmentStatePagerAdapter
to see how this is done.
This is the class I use. Works like RandomNumber.GenerateRandom(1, 666)
internal static class RandomNumber
{
private static Random r = new Random();
private static object l = new object();
private static Random globalRandom = new Random();
[ThreadStatic]
private static Random localRandom;
public static int GenerateNewRandom(int min, int max)
{
return new Random().Next(min, max);
}
public static int GenerateLockedRandom(int min, int max)
{
int result;
lock (RandomNumber.l)
{
result = RandomNumber.r.Next(min, max);
}
return result;
}
public static int GenerateRandom(int min, int max)
{
Random random = RandomNumber.localRandom;
if (random == null)
{
int seed;
lock (RandomNumber.globalRandom)
{
seed = RandomNumber.globalRandom.Next();
}
random = (RandomNumber.localRandom = new Random(seed));
}
return random.Next(min, max);
}
}
I found this related question on the topic, but if you want direct links, here they are:
I'm surprised node.js doesn't come with a shell, but I guess it's really more like an epoll/selector-based callback/event-oriented webserver, so perhaps it doesn't need the full JS feature set, but I'm not too familiar with its inner workings.
Since you seem interested in node.js and since it's based on V8, it might be best to follow those instructions on getting a V8 environment set up so you can have a consistent basis for your JavaScript programming (I should hope JSC and V8 are mostly the same, but I'm not sure).
set a rule to check the file name (if the form is multipart)
$this->form_validation->set_rules('upload_file[name]', 'Upload file', 'required', 'No upload image :(');
overwrite the $_POST
array as follows:
$_POST['upload_file'] = $_FILES['upload_file']
and then do:
$this->form_validation->run()
you have a date string like this, "24052010" and you want date object for this,
from datetime import datetime
cus_date = datetime.strptime("24052010", "%d%m%Y").date()
this cus_date will give you date object.
you can retrieve date string from your date object using this,
cus_date.strftime("%d%m%Y")

I came across this question because I had a problem when following the answers, so I post my solution here.
The above examples all show samples with strings containing only ASCII values, in which case everything works fine. However, when dealing with strings in Windows whcih can also contain other characters, like german umlauts, then these solutions don't work
The only code that gives correct results in such cases is
std::string s = "Übernahme";
QString q = QString::fromLocal8Bit(s.c_str());
If you don't have to deal with such strings, then the above answers will work fine.
Difference b/w scp and rsync on different parameter
scp
: scp is relatively less optimise and speed
rsync
: rsync is comparatively more optimise and speed
scp
: scp command line tool cannot resume aborted downloads from lost network connections
rsync
: If the above rsync session itself gets interrupted, you can resume it as many time as you want by typing the same command. rsync will automatically restart the transfer where it left off.
http://ask.xmodulo.com/resume-large-scp-file-transfer-linux.html
$ scp source_file_path destination_file_path
$ cd /path/to/directory/of/partially_downloaded_file
$ rsync -P --rsh=ssh [email protected]:bigdata.tgz ./bigdata.tgz
The -P
option is the same as --partial --progress
, allowing rsync to work with partially downloaded files. The --rsh=ssh
option tells rsync to use ssh as a remote shell.
scp is more secure. You have to use rsync --rsh=ssh
to make it as secure as scp.

To be more semantically correct and answer the OPs orginal question about aligning them side by side I would use this:

<figure>

./
refers to the current working directory, except in the require()
function. When using require()
, it translates ./
to the directory of the current file called. __dirname
is always the directory of the current file.
For example, with the following file structure
/home/user/dir/files/config.json
{
"hello": "world"
}
/home/user/dir/files/somefile.txt
text file
/home/user/dir/dir.js
var fs = require('fs');
console.log(require('./files/config.json'));
console.log(fs.readFileSync('./files/somefile.txt', 'utf8'));
If I cd
into /home/user/dir
and run node dir.js
I will get
{ hello: 'world' }
text file
But when I run the same script from /home/user/
I get
{ hello: 'world' }
Error: ENOENT, no such file or directory './files/somefile.txt'
at Object.openSync (fs.js:228:18)
at Object.readFileSync (fs.js:119:15)
at Object.<anonymous> (/home/user/dir/dir.js:4:16)
at Module._compile (module.js:432:26)
at Object..js (module.js:450:10)
at Module.load (module.js:351:31)
at Function._load (module.js:310:12)
at Array.0 (module.js:470:10)
at EventEmitter._tickCallback (node.js:192:40)
Using ./
worked with require
but not for fs.readFileSync
. That's because for fs.readFileSync
, ./
translates into the cwd (in this case /home/user/
). And /home/user/files/somefile.txt
does not exist.
Actually, it is

At least if you look at the .NET library, which IMO is the best way to decide naming conventions - so your code doesn't look out of place.
It's been a while since I posted this, but I thought I would show how I figured it out (as best as I recall now).
I did a Maven dependency tree to find dependency conflicts, and I removed all conflicts with exclusions in dependencies, e.g.:
<dependency>
<groupId>commons-logging</groupId>
<artifactId>commons-logging-api</artifactId>
<version>1.1</version>
<exclusions>
<exclusion>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
</exclusion>
</exclusions>
</dependency>
Also, I used the provided
scope for javax.servlet dependencies so as not to introduce an additional conflict with what is provided by Tomcat when I run the app.
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.1</version>
<scope>provided</scope>
</dependency>
HTH.
In order to put the number in the correct order i modified your code to have a variable (s) for the output. This allows you to put the characters in the correct order.
s=""
def ChangeHex(n):
if (n < 0):
print(0)
elif (n<=1):
print(n)
else:
x =(n%16)
if (x < 10):
s=str(x)+s,
if (x == 10):
s="A"+s,
if (x == 11):
s="B"+s,
if (x == 12):
s="C"+s,
if (x == 13):
s="D"+s,
if (x == 14):
s="E"+s,
if (x == 15):
s="F"+s,
ChangeHex( n / 16 )
NOTE: This was done in python 3.7.4 so it may not work for you.
You can use us jquery function getJson :

If there are multiple ways a user might order person, you could also have multiple Comparators setup as constants somewhere. Most of the sort operations and sorted collections take a comparator as a parameter.
Just to complement m59's correct answer, here is a working jsfiddle:

Another simple way to exclude the auto configuration classes,
Add below similar configuration to your application.yml file,
---
spring:
profiles: test
autoconfigure.exclude: org.springframework.boot.autoconfigure.session.SessionAutoConfiguration
Try this:
$str = htmlentities($str,ENT_QUOTES,'UTF-8');
So, after filtering your data using htmlentities()
function, you can use the data in XML tag like:
<mytag>$str</mytag>
If you don't care about dirty reads (i.e. in a predominately READ situation), then NOLOCK
is fine.
BUT, be aware that the majority of locking problems are due to not having the 'correct' indexes for your query workload (assuming the hardware is up to the task).
And the guru's explanation was correct. It is usually a band-aid solution to a more serious problem.
Edit: I'm definitely not suggesting that NOLOCK should be used. I guess I should have made that obviously clear. (I would only ever use it, in extreme circumstances where I had analysed that it was OK). AS an example, a while back I worked on some TSQL that had been sprinkled with NOLOCK to try and alleviate locking problems. I removed them all, implemented the correct indexes, and ALL of the deadlocks went away.
For game authoring, one of the best solutions is to use a library which solves the many problems we face when writing code for the web, such as howler.js. howler.js abstracts the great (but low-level) Web Audio API into an easy to use framework. It will attempt to fall back to HTML5 Audio Element if Web Audio API is unavailable.
var sound = new Howl({
urls: ['sound.mp3', 'sound.ogg']
}).play();
// it also provides calls for spatial/3d audio effects (most browsers)
sound.pos3d(0.1,0.3,0.5);
Another great library is wad.js, which is especially useful for producing synth audio, such as music and effects. For example:
var saw = new Wad({source : 'sawtooth'})
saw.play({
volume : 0.8,
wait : 0, // Time in seconds between calling play() and actually triggering the note.
loop : false, // This overrides the value for loop on the constructor, if it was set.
pitch : 'A4', // A4 is 440 hertz.
label : 'A', // A label that identifies this note.
env : {hold : 9001},
panning : [1, -1, 10],
filter : {frequency : 900},
delay : {delayTime : .8}
})
Another library similar to Wad.js is "Sound for Games", it has more focus on effects production, while providing a similar set of functionality through a relatively distinct (and perhaps more concise feeling) API:
function shootSound() {
soundEffect(
1046.5, //frequency
0, //attack
0.3, //decay
"sawtooth", //waveform
1, //Volume
-0.8, //pan
0, //wait before playing
1200, //pitch bend amount
false, //reverse bend
0, //random pitch range
25, //dissonance
[0.2, 0.2, 2000], //echo array: [delay, feedback, filter]
undefined //reverb array: [duration, decay, reverse?]
);
}
Each of these libraries are worth a look, whether you need to play back a single sound file, or perhaps create your own html-based music editor, effects generator, or video game.
Solved. The problem is, executable is working in a different way in Linux. If you want to run an .sh
file, you should add the exec-maven-plugin to the <plugins>

file.

<version>3.0.0</version>
<groupId>org.codehaus.mojo</groupId>

You can also edit the preferences file by hand to set the Array Fetch Size to any value.
Mine is found at C:\Users\<user>\AppData\Roaming\SQL Developer\system4.0.2.15.21\o.sqldeveloper.12.2.0.15.21\product-preferences.xml
on Win 7 (x64).
The value is on line 372 for me and reads <value n="ARRAYFETCHSIZE" v="200"/>
I have changed it to 2000 and it works for me.
I had to restart SQL Developer.
The idea of MD5 is that is a one-way hashing, so it can't be once the original value has been passed through the hashing algorithm (if at all).
You could (potentially) create a database table with a pairing of the original and the MD5 values but I guess that's highly impractical and poses a major security risk.
Download java-json.jar from here, which contains org.json.JSONArray

Specifically for boolean is*()
getters:
I've spend a lot of time on why neither below
@JsonAutoDetect(fieldVisibility = Visibility.ANY, getterVisibility = Visibility.NONE, setterVisibility = Visibility.NONE)
nor this
setVisibility(PropertyAccessor.SETTER, JsonAutoDetect.Visibility.NONE);
setVisibility(PropertyAccessor.GETTER, JsonAutoDetect.Visibility.NONE);
setVisibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY);
worked for my Boolean Getter/Setter.
Solution is simple:
@JsonAutoDetect(isGetterVisibility = Visibility.NONE, ...
setVisibility(PropertyAccessor.IS_GETTER, JsonAutoDetect.Visibility.NONE);
UPDATE: spring-boot allowed configure it:
jackson:
visibility.field: any
visibility.getter: none
visibility.setter: none
visibility.is-getter: none
I would use following Guava API: com.google.common.collect.Maps#fromProperties
Properties properties = new Properties();
Map<String, String> map = Maps.fromProperties(properties);
There are two method two remove index in mysql. First method is GUI. In this method you have to open GUI interface of MYSQL and then go to that database and then go to that particular table in which you want to remove index.
After that click on the structure option, Then you can see table structure and below you can see table indexes. You can remove indexes by clicking on drop option
Second method by
ALTER TABLE student_login_credentials DROP INDEX created_at;
here student_login_credentials is table name and created_at is column name
Try this:
$('#myAnchor')[0].click();
It works for me.

Use the readonly

<input type="text" readonly />
I solved this problem by adding C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\System.Runtime.Serialization.dll in the reference
<div id='child' style='width: 50px; height: 100px; margin:0 auto;'>Text</div>
This might work for you
public void save(String fileName) throws FileNotFoundException {
FileOutputStream fout= new FileOutputStream (fileName);
ObjectOutputStream oos = new ObjectOutputStream(fout);
oos.writeObject(clubs);
fout.close();
}
To read back you can have
public void read(String fileName) throws FileNotFoundException {
FileInputStream fin= new FileInputStream (fileName);
ObjectInputStream ois = new ObjectInputStream(fin);
clubs= (ArrayList<Clubs>)ois.readObject();
fin.close();
}
The Hashset
Internally implements HashMap
. If you see the internal implementation the values inserted in HashSet are stored as keys in the HashMap and the value is a Dummy object of Object class.
Difference between HashMap vs HashSet is:-
HashMap
contains key value pairs and each value can be accessed by key where as HashSet needs to be iterated everytime as there is no get method.HashMap
implements Map interface and allows one null value as a key and multiple null values as values.Where as HashSet
implements Set interface, allows only one null value and no duplicated values.(Remeber one null key is allowed in HashMap key hence one null value in HashSet as HashSet implemements HashMap internally). HashSet
and HashMap
does not maintain the order of insertion while iterating.I believe app:itemBackground
expects a drawable. So follow the steps below :
Make a drawable file highlight_color.xml
with following contents :
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid android:color="YOUR HIGHLIGHT COLOR"/>
</shape>
Make another drawable file nav_item_drawable.xml
with following contents:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/highlight_color" android:state_checked="true"/>
</selector>
Finally add app:itemBackground
tag in the NavView :
<android.support.design.widget.NavigationView
android:id="@+id/activity_main_navigationview"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/drawer_header"
app:itemIconTint="@color/black"
app:itemTextColor="@color/primary_text"
app:itemBackground="@drawable/nav_item_drawable"
app:menu="@menu/menu_drawer">
here the highlight_color.xml file defines a solid color drawable for the background. Later this color drawable is assigned to nav_item_drawable.xml selector.
This worked for me. Hopefully this will help.
********************************************** UPDATED **********************************************
Though the above mentioned answer gives you fine control over some properties, but the way I am about to describe feels more SOLID and is a bit COOLER.
So what you can do is, you can define a ThemeOverlay in the styles.xml
for the NavigationView like this :
<style name="ThemeOverlay.AppCompat.navTheme">
<!-- Color of text and icon when SELECTED -->
<item name="colorPrimary">@color/color_of_your_choice</item>
<!-- Background color when SELECTED -->
<item name="colorControlHighlight">@color/color_of_your_choice</item>
</style>
now apply this ThemeOverlay to app:theme
attribute of NavigationView, like this:
<android.support.design.widget.NavigationView
android:id="@+id/activity_main_navigationview"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:theme="@style/ThemeOverlay.AppCompat.navTheme"
app:headerLayout="@layout/drawer_header"
app:menu="@menu/menu_drawer">
I hope this will help.
If you are migrating to ASP.NET Core MVC from .Net Framework MVC like I was, things have changed slightly. The ajax call must be on the raw object using stringify so rather than passing data of { vals: arrayOfValues }
it should be JSON.stringify(arrayOfValues)
as follows:
$.ajax({
url: 'controller/myaction',
data: JSON.stringify(arrayOfValues),
success: function(data) { /* Whatever */ }
});
The other change that has been made in ASP.NET Core is to prevent cross-site request forgery so for calls to an MVC action from an ajax method the [FromBody]
atribute must be applied to the action parameter as follows:
public ActionResult MyAction([FromBody] IEnumerable<int> arrayOfValues )
This is an old post but maybe this could help people to complete the CORS problem. To complete the basic authorization problem you should avoid authorization for OPTIONS requests in your server. This is an Apache configuration example. Just add something like this in your VirtualHost or Location.
<LimitExcept OPTIONS>
AuthType Basic
AuthName <AUTH_NAME>
Require valid-user
AuthUserFile <FILE_PATH>
</LimitExcept>
If you're running Angular 2 through ASP.NET Core 1 in Visual Studio 2015, you might find this solution from Jürgen Gutsch helpful. He describes it in a blog post. It was the best solution for me. Place the C# code provided below in your Startup.cs public void Configure() just before app.UseStaticFiles();
app.Use( async ( context, next ) => {
await next();
if( context.Response.StatusCode == 404 && !Path.HasExtension( context.Request.Path.Value ) ) {
context.Request.Path = "/index.html";
await next();
}
});
I don't think you need a case statement. You just need to update your where clause and make sure you have correct parentheses to group the clauses.
SELECT Sum(CAMount) as PaymentAmount
from TableOrderPayment
where (CStatus = 'Active' AND CPaymentType = 'Cash')
OR (CStatus = 'Active' and CPaymentType = 'Check' and CDate<=SYSDATETIME())
The answers posted before mine assume that CDate<=SYSDATETIME() is also appropriate for Cash payment type as well. I think I split mine out so it only looks for that clause for check payments.
It depends on your definition of what memory query you wish to get.
Usually, you'd like to know the status of the heap memory, since if it uses too much memory, you get OOM and crash the app.
For this, you can check the next values:
final Runtime runtime = Runtime.getRuntime();
final long usedMemInMB=(runtime.totalMemory() - runtime.freeMemory()) / 1048576L;
final long maxHeapSizeInMB=runtime.maxMemory() / 1048576L;
final long availHeapSizeInMB = maxHeapSizeInMB - usedMemInMB;
The more the "usedMemInMB" variable gets close to "maxHeapSizeInMB", the closer availHeapSizeInMB
gets to zero, the closer you get OOM. (Due to memory fragmentation, you may get OOM BEFORE this reaches zero.)
That's also what the DDMS tool of memory usage shows.
Alternatively, there is the real RAM usage, which is how much the entire system uses - see accepted answer to calculate that.
Update: since Android O makes your app also use the native RAM (at least for Bitmaps storage, which is usually the main reason for huge memory usage), and not just the heap, things have changed, and you get less OOM (because the heap doesn't contain bitmaps anymore,check here), but you should still keep an eye on memory use if you suspect you have memory leaks. On Android O, if you have memory leaks that should have caused OOM on older versions, it seems it will just crash without you being able to catch it. Here's how to check for memory usage:
val nativeHeapSize = Debug.getNativeHeapSize()
val nativeHeapFreeSize = Debug.getNativeHeapFreeSize()
val usedMemInBytes = nativeHeapSize - nativeHeapFreeSize
val usedMemInPercentage = usedMemInBytes * 100 / nativeHeapSize
But I believe it might be best to use the profiler of the IDE, which shows the data in real time, using a graph.
So the good news on Android O is that it's much harder to get crashes due to OOM of storing too many large bitmaps, but the bad news is that I don't think it's possible to catch such a case during runtime.
EDIT: seems Debug.getNativeHeapSize()
changes over time, as it shows you the total max memory for your app. So those functions are used only for the profiler, to show how much your app is using.
If you want to get the real total and available native RAM , use this:
val memoryInfo = ActivityManager.MemoryInfo()
(getSystemService(Context.ACTIVITY_SERVICE) as ActivityManager).getMemoryInfo(memoryInfo)
val nativeHeapSize = memoryInfo.totalMem
val nativeHeapFreeSize = memoryInfo.availMem
val usedMemInBytes = nativeHeapSize - nativeHeapFreeSize
val usedMemInPercentage = usedMemInBytes * 100 / nativeHeapSize
Log.d("AppLog", "total:${Formatter.formatFileSize(this, nativeHeapSize)} " +
"free:${Formatter.formatFileSize(this, nativeHeapFreeSize)} " +
"used:${Formatter.formatFileSize(this, usedMemInBytes)} ($usedMemInPercentage%)")

For me an easier, practical and direct way to understand what is going on, is that the following enumeration:
enum colors { red, green, blue };
Will be converted essentially to this:
var colors = { red: 0, green: 1, blue: 2,
[0]: "red", [1]: "green", [2]: "blue" }
Because of this, the following will be true:
colors.red === 0
colors[colors.red] === "red"
colors["red"] === 0
This creates a easy way to get the name of an enumerated as follows:
var color: colors = colors.red;
console.log("The color selected is " + colors[color]);
It also creates a nice way to convert a string to an enumerated value.
var colorName: string = "green";
var color: colors = colors.red;
if (colorName in colors) color = colors[colorName];
The two situations above are far more common situation, because usually you are far more interested in the name of a specific value and serializing values in a generic way.
Override using JavaScript
$('.mytable td').attr('style', 'display: none !important');
Worked for me.
UPDATE: more efficient solutions have been proposed, uniform_filter1d
from scipy
being probably the best among the "standard" 3rd-party libraries, and some newer or specialized libraries are available too.
You can use np.convolve
for that:
np.convolve(x, np.ones(N)/N, mode='valid')
The running mean is a case of the mathematical operation of convolution. For the running mean, you slide a window along the input and compute the mean of the window's contents. For discrete 1D signals, convolution is the same thing, except instead of the mean you compute an arbitrary linear combination, i.e., multiply each element by a corresponding coefficient and add up the results. Those coefficients, one for each position in the window, are sometimes called the convolution kernel. The arithmetic mean of N values is (x_1 + x_2 + ... + x_N) / N
, so the corresponding kernel is (1/N, 1/N, ..., 1/N)
, and that's exactly what we get by using np.ones(N)/N
.
The mode
argument of np.convolve
specifies how to handle the edges. I chose the valid
mode here because I think that's how most people expect the running mean to work, but you may have other priorities. Here is a plot that illustrates the difference between the modes:
import numpy as np
import matplotlib.pyplot as plt
modes = ['full', 'same', 'valid']
for m in modes:
plt.plot(np.convolve(np.ones(200), np.ones(50)/50, mode=m));
plt.axis([-10, 251, -.1, 1.1]);
plt.legend(modes, loc='lower center');
plt.show()
Timestamptz vs Timestamp
The timestamptz field in Postgres is basically just the timestamp field where Postgres actually just stores the “normalised” UTC time, even if the timestamp given in the input string has a timezone.
If your input string is: 2018-08-28T12:30:00+05:30 , when this timestamp is stored in the database, it will be stored as 2018-08-28T07:00:00.
The advantage of this over the simple timestamp field is that your input to the database will be timezone independent, and will not be inaccurate when apps from different timezones insert timestamps, or when you move your database server location to a different timezone.
To quote from the docs:
For timestamp with time zone, the internally stored value is always in UTC (Universal Coordinated Time, traditionally known as Greenwich Mean Time, GMT). An input value that has an explicit time zone specified is converted to UTC using the appropriate offset for that time zone. If no time zone is stated in the input string, then it is assumed to be in the time zone indicated by the system’s TimeZone parameter, and is converted to UTC using the offset for the timezone zone. To give a simple analogy, a timestamptz value represents an instant in time, the same instant for anyone viewing it. But a timestamp value just represents a particular orientation of a clock, which will represent different instances of time based on your timezone.
For pretty much any use case, timestamptz is almost always a better choice. This choice is made easier with the fact that both timestamptz and timestamp take up the same 8 bytes of data.

If you are using Outlook to send a static image with hyperlink, an easy way would be to use Word.
You can do something like this:
var radios = document.getElementsByName('genderS');_x000D_
_x000D_
for (var i = 0, length = radios.length; i < length; i++) {_x000D_
if (radios[i].checked) {_x000D_
// do whatever you want with the checked radio_x000D_
alert(radios[i].value);_x000D_
_x000D_
// only one radio can be logically checked, don't check the rest_x000D_
break;_x000D_
}_x000D_
}
_x000D_
<label for="gender">Gender: </label>_x000D_
<input type="radio" name="genderS" value="1" checked="checked">Male</input>_x000D_
<input type="radio" name="genderS" value="0">Female</input>
_x000D_

Another option, using the command module:
- name: Create file
command: touch /path/to/file
args:
creates: /path/to/file
The 'creates' argument ensures that this action is not performed if the file exists.
You can read JNE/Z as *
Jump if the status is "Not set" on Equal/Zero flag
"Not set" is a status when "equal/zero flag" in the CPU is set to 0 which only happens when the condition is met or equally matched.
You can use jQuery's filter() function to achieve this.
$("p").filter(function() {
// Matches exact string
return $(this).text() === "Hello World";
}).css("font-weight", "bold");
As it is written in the documentation you have to change the cell type to a markdown.
If you have access to a console in the context you are investigating, you can determine which version you are running by printing the value of the global constant RUBY_VERSION
.
The problem is that once the page is served up, the content is going to be in the encoding described in the content-type meta tag. The content in "wrong" encoding is already garbled.
You're best to do this on the server before serving up the page. Or as I have been know to say: UTF-8 end-to-end or die.
Yes you can do that by just creating a BroadcastReceiver
that calls your Service
when your Application boots. Here is a complete answer given by me.
Android - Start service on boot
If you don't want any icon/launcher for you Application you can do that also, just don't create any Activity with
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
Just declare your Service
as declared normally.
Run this code it will take input as audio(microphone) and convert into the text than audio play.

If your python >= 3.6, F-string formatted literal is your new friend.
It's more simple, clean, and better performance.
In [1]: params=['Hello', 'adam', 42]
In [2]: %timeit "%s %s, the answer to everything is %d."%(params[0],params[1],params[2])
448 ns ± 1.48 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
In [3]: %timeit "{} {}, the answer to everything is {}.".format(*params)
449 ns ± 1.42 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)
In [4]: %timeit f"{params[0]} {params[1]}, the answer to everything is {params[2]}."
12.7 ns ± 0.0129 ns per loop (mean ± std. dev. of 7 runs, 100000000 loops each)
You could also use operator.concat()
like this:
>>> from operator import concat
>>> a = ['a', 'b', 'c', 'd']
>>> reduce(concat, a)
'abcd'
If you're using Python 3 you need to prepend:
>>> from functools import reduce
since the builtin reduce()
has been removed from Python 3 and now lives in functools.reduce()

Rishav Rastogi is right, and with rails 3.0 or higher its:
rails generate scaffold ...
rails destroy scaffold ...
This is exactly what the OUTPUT
clause in SQL Server 2005 onwards is excellent for.
EXAMPLE
CREATE TABLE [dbo].[test_table](
[LockId] [int] IDENTITY(1,1) NOT NULL,
[StartTime] [datetime] NULL,
[EndTime] [datetime] NULL,
PRIMARY KEY CLUSTERED
(
[LockId] ASC
) ON [PRIMARY]
) ON [PRIMARY]
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 07','2009 JUL 07')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 08','2009 JUL 08')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 09','2009 JUL 09')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 10','2009 JUL 10')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 11','2009 JUL 11')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 12','2009 JUL 12')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 13','2009 JUL 13')
UPDATE test_table
SET StartTime = '2011 JUL 01'
OUTPUT INSERTED.* -- INSERTED reflect the value after the UPDATE, INSERT, or MERGE statement is completed
WHERE
StartTime > '2009 JUL 09'
Results in the following being returned
LockId StartTime EndTime
-------------------------------------------------------
4 2011-07-01 00:00:00.000 2009-07-10 00:00:00.000
5 2011-07-01 00:00:00.000 2009-07-11 00:00:00.000
6 2011-07-01 00:00:00.000 2009-07-12 00:00:00.000
7 2011-07-01 00:00:00.000 2009-07-13 00:00:00.000
In your particular case, since you cannot use aggregate functions with OUTPUT
, you need to capture the output of INSERTED.*
in a table variable or temporary table and count the records. For example,
DECLARE @temp TABLE (
[LockId] [int],
[StartTime] [datetime] NULL,
[EndTime] [datetime] NULL
)
UPDATE test_table
SET StartTime = '2011 JUL 01'
OUTPUT INSERTED.* INTO @temp
WHERE
StartTime > '2009 JUL 09'
-- now get the count of affected records
SELECT COUNT(*) FROM @temp
What's dumpsys and what are its benefit
dumpsys is an android tool that runs on the device and dumps interesting information about the status of system services.
Obvious benefits:
What information can we retrieve from dumpsys shell command and how we can use it
If you run dumpsys you would see a ton of system information. But you can use only separate parts of this big dump.
to see all of the "subcommands" of dumpsys do:
dumpsys | grep "DUMP OF SERVICE"
Output:

dumpsys is ultimately flexible and useful tool!
If you want to use this tool do not forget to add permission into your android manifest automatically android.permission.DUMP
Try to test all commands to learn more about dumpsys. Happy dumping!
For windows 10,
worked for me.
EDIT:
Indeed there was a patch which included sign()
in math, but it wasn't accepted, because they didn't agree on what it should return in all the edge cases (+/-0, +/-nan, etc)
So they decided to implement only copysign, which (although more verbose) can be used to delegate to the end user the desired behavior for edge cases - which sometimes might require the call to cmp(x,0)
.
I don't know why it's not a built-in, but I have some thoughts.
copysign(x,y):
Return x with the sign of y.
Most importantly, copysign
is a superset of sign
! Calling copysign
with x=1 is the same as a sign
function. So you could just use copysign
and forget about it.
>>> math.copysign(1, -4)
-1.0
>>> math.copysign(1, 3)
1.0
If you get sick of passing two whole arguments, you can implement sign
this way, and it will still be compatible with the IEEE stuff mentioned by others:
>>> sign = functools.partial(math.copysign, 1) # either of these
>>> sign = lambda x: math.copysign(1, x) # two will work
>>> sign(-4)
-1.0
>>> sign(3)
1.0
>>> sign(0)
1.0
>>> sign(-0.0)
-1.0
>>> sign(float('nan'))
-1.0
Secondly, usually when you want the sign of something, you just end up multiplying it with another value. And of course that's basically what copysign
does.
So, instead of:
s = sign(a)
b = b * s
You can just do:
b = copysign(b, a)
And yes, I'm surprised you've been using Python for 7 years and think cmp
could be so easily removed and replaced by sign
! Have you never implemented a class with a __cmp__
method? Have you never called cmp
and specified a custom comparator function?
In summary, I've found myself wanting a sign
function too, but copysign
with the first argument being 1 will work just fine. I disagree that sign
would be more useful than copysign
, as I've shown that it's merely a subset of the same functionality.
Most devices have some form of emulated storage. if they support sd cards they are usually mounted to /sdcard
(or some variation of that name) which is usually symlinked to to a directory in /storage
like /storage/sdcard0
or /storage/0
sometimes the emulated storage is mounted to /sdcard
and the actual path is something like /storage/emulated/legacy. You should be able to use to get the downloads directory. You are best off using the api calls to get directories.
Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);
Since the filesystems and sdcard support varies among devices.
see similar question for more info how to access downloads folder in android?
Usually the DownloadManager handles downloads and the files are then accessed by requesting the file's uri fromthe download manager using a file id to get where file was places which would usually be somewhere in the sdcard/ real or emulated since apps can only read data from certain places on the filesystem outside of their data directory like the sdcard
Maybe all fields of your POJO need Getter and Setter.
I fixed it according to this issue. reference:Spring MVC - HttpMediaTypeNotAcceptableException
And 406 is not a useful message to fix the bug. You should debug into the codes and see what the Exception is on earth.
The above final .htaccess and Test A,B,C,D,E did not work for me. I just used below 2 lines code and it works in my WordPress website:

RewriteRule ^(.*)$ https://www.thehotskills.com/$1 [R=301,L]
I'm not sure where I was making the mistake but this page helped me out.

Ben Nadel has written a good article about this, he points out the difference in the parameters to these functions:
String.slice( begin [, end ] )
String.substring( from [, to ] )
String.substr( start [, length ] )
He also points out that if the parameters to slice are negative, they reference the string from the end. Substring and substr doesn't.
Here is his article about this.
lst = [("aaaa8"),("bb8"),("ccc8"),("dddddd8")...]
msg = filter(lambda x : x != "8", lst)
print msg
EDIT: For anyone who came across this post, just for understanding the above removes any elements from the list which are equal to 8.
Supposing we use the above example the first element ("aaaaa8") would not be equal to 8 and so it would be dropped.
To make this (kinda work?) with how the intent of the question was we could perform something similar to this
msg = filter(lambda x: x != "8", map(lambda y: list(y), lst))
What this does is split each element of list up into an array of characters so ("aaaa8") would become ["a", "a", "a", "a", "8"].
This would result in a data type that looks like this
msg = [["a", "a", "a", "a"], ["b", "b"]...]
So finally to wrap that up we would have to map it to bring them all back into the same type roughly
msg = list(map(lambda q: ''.join(q), filter(lambda x: x != "8", map(lambda y: list(y[0]), lst))))
I would absolutely not recommend it, but if you were really wanting to play with map and filter, that would be how I think you could do it with a single line.
If you want to take control of /usr/bin/
You will need to reboot your system:
Right after the boot sound, Hold down Command-R to boot into the Recovery System
Click the Utilities menu and select Terminal
Type csrutil disable and press return
Click the ? menu and select Restart
Once you have committed your changes, make sure to re-enable SIP! It does a lot to protect your system. (Same steps as above except type: csrutil enable)
This one is working well in MS SQL. It transforms varchar to the result of two-decimal-places-limited float.
Select field1, cast(Try_convert(float,(Count(field2)* 100) /
Try_convert(float, (Select Count(*) From table1))) as decimal(10,2)) as new_field_name
From table1
Group By field1, field2;
this is to topup to what was selected as the correct answer. It has one missing step that when not done, the user will still be able to access the rest of the database. First, do as @DineshDB suggested
1. Connect to your SQL server instance using management studio
2. Goto Security -> Logins -> (RIGHT CLICK) New Login
3. fill in user details
4. Under User Mapping, select the databases you want the user to be able to access and configure
the missing step is below:
5. Under user mapping, ensure that "sysadmin" is NOT CHECKED and select "db_owner" as the role for the new user.
And thats it.

For SQL Management studio I used a variation of BWS' answer. This gets the data to the right of '=', or NULL if the symbol doesn't exist:
CASE WHEN (RIGHT(supplier_reference, CASE WHEN (CHARINDEX('=',supplier_reference,0)) = 0 THEN
0 ELSE CHARINDEX('=', supplier_reference) -1 END)) <> '' THEN (RIGHT(supplier_reference, CASE WHEN (CHARINDEX('=',supplier_reference,0)) = 0 THEN
0 ELSE CHARINDEX('=', supplier_reference) -1 END)) ELSE NULL END
In SQL Server , cast text as datetime
select cast('5/21/2013 9:45:48' as datetime)
At a minimum, change this:
function BlockID() {
var IDs = new Array();
images['s'] = "Images/Block_01.png";
images['g'] = "Images/Block_02.png";
images['C'] = "Images/Block_03.png";
images['d'] = "Images/Block_04.png";
return IDs;
}
To this:
function BlockID() {
var IDs = new Object();
IDs['s'] = "Images/Block_01.png";
IDs['g'] = "Images/Block_02.png";
IDs['C'] = "Images/Block_03.png";
IDs['d'] = "Images/Block_04.png";
return IDs;
}
There are a couple fixes to point out. First, images
is not defined in your original function, so assigning property values to it will throw an error. We correct that by changing images
to IDs
. Second, you want to return an Object
, not an Array
. An object can be assigned property values akin to an associative array or hash -- an array cannot. So we change the declaration of var IDs = new Array();
to var IDs = new Object();
.
After those changes your code will run fine, but it can be simplified further. You can use shorthand notation (i.e., object literal property value shorthand) to create the object and return it immediately:
function BlockID() {
return {
"s":"Images/Block_01.png"
,"g":"Images/Block_02.png"
,"C":"Images/Block_03.png"
,"d":"Images/Block_04.png"
};
}
Just to provide some variation here: You could check for
if ($_SERVER["QUERY_STRING"] == null)
it is completely identical to testing $_GET
.

I got this error because such DLL (and many others) were missing in bin folder when I pubished the web application. It seemed like a bug in Visual Studio publish function. Cleaning, recompiling and publishing it again, made such DLLs to be published correctly.
You can use Character.toString(char)
. Note that this method simply returns a call to String.valueOf(char)
, which also works.
As others have noted, string concatenation works as a shortcut as well:
String s = "" + 's';
But this compiles down to:
String s = new StringBuilder().append("").append('s').toString();
which is less efficient because the StringBuilder
is backed by a char[]
(over-allocated by StringBuilder()
to 16
), only for that array to be defensively copied by the resulting String
.
String.valueOf(char)
"gets in the back door" by wrapping the char
in a single-element array and passing it to the package private constructor String(char[], boolean)
, which avoids the array copy.
Explanation from the Preshing on Programming blog:
It’s handy when you have two related operations which you’d like to execute as a pair, with a block of code in between. The classic example is opening a file, manipulating the file, then closing it:
with open('output.txt', 'w') as f: f.write('Hi there!')
The above with statement will automatically close the file after the nested block of code. (Continue reading to see exactly how the close occurs.) The advantage of using a with statement is that it is guaranteed to close the file no matter how the nested block exits. If an exception occurs before the end of the block, it will close the file before the exception is caught by an outer exception handler. If the nested block were to contain a return statement, or a continue or break statement, the with statement would automatically close the file in those cases, too.
In case you're not in the specified directory (i.e. direct), you should use (in linux):
x_file = open('path/to/direct/filename.txt')
Note the quotes and the relative path to the directory.
This may be your problem, but you also don't have permission to access that file. Maybe you're trying to open it as another user.
You should verify following things if the two way binding does not work.
In html the ngModel should be called this way. There is no dependency on other attribute of the input element
<input [(ngModel)]="inputText">
Make Sure FormsModule is imported into the modules file
app.modules.ts
import { FormsModule } from '@angular/forms';
@NgModule({
declarations: [
AppComponent,
HomeComponent // suppose, this is the component in which you are trying to use two ay binding
],
imports: [
BrowserModule,
FormsModule,
// other modules
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Make sure the component in which you are trying to use ngModel for two way binding is added in the declarations of the. Code added in the previous point #2
This is everything that you need to do to make the two way binding using ngModel work, this is validated up to angular 9
You probably need to do a git stash
before you git pull
, this is because it is reading your old config file. So do:
git stash
git pull
git commit -am <"say first commit">
git push
Also see git-stash(1) Manual Page.
There's a solution for multi-line text with pure css. It's called line-clamp
, but it only works in webkit browsers. There is however a way to mimic this in all modern browsers (everything more recent than IE8.) Also, it will only work on solid backgrounds because you need a background-image to hide the last words of the last line. Here's how it goes:
Given this html:
<p class="example" id="example-1">

Here's the CSS:
p {
position:relative;
line-height:1.4em;
height:4.2em; /* 3 times the line-height to show 3 lines */
}
p::after {
content:"...";
font-weight:bold;
position:absolute;
bottom:0;
right:0;
padding:0 20px 1px 45px;
background:url(ellipsis_bg.png) repeat-y;
}
ellipsis_bg.png being an image of the same color of your background, that would be about 100px wide and have the same height as your line-height.
It's not very pretty, as your text may be cut of in the middle of a letter, but it may be useful in some cases.
Reference: http://www.css-101.org/articles/line-clamp/line-clamp_for_non_webkit-based_browsers.php
<%= link_to "http://www.facebook.com/sharer.php?u=" + article_url(article, :text => article.title), :class => "btn btn-primary" do %> <i class="fa fa-facebook"> Facebook Share </i> <%end%>
I am assuming that current_article_url
is http://0.0.0.0:4567/link_to_title
#collect
is actually an alias for #map
. That means the two methods can be used interchangeably, and effect the same behavior.
I finally made it work using code examples from this Undo/Redo Manager Tutorial.
This is exactly what you need to do:
- (void)applicationDidFinishLaunching:(UIApplication *)application {
application.applicationSupportsShakeToEdit = YES;
[window addSubview:viewController.view];
[window makeKeyAndVisible];
}
-(BOOL)canBecomeFirstResponder {
return YES;
}
-(void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
[self becomeFirstResponder];
}
- (void)viewWillDisappear:(BOOL)animated {
[self resignFirstResponder];
[super viewWillDisappear:animated];
}
- (void)motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event
{
if (motion == UIEventSubtypeMotionShake)
{
// your code
}
}
I have edited the code from one of the example here to use jquery. It's still not 100% jquery though. Any thoughts on the two different versions, like what are the pros and cons of each?
function column_sort() {
getCellValue = (tr, idx) => $(tr).find('td').eq( idx ).text();
comparer = (idx, asc) => (a, b) => ((v1, v2) =>
v1 !== '' && v2 !== '' && !isNaN(v1) && !isNaN(v2) ? v1 - v2 : v1.toString().localeCompare(v2)
)(getCellValue(asc ? a : b, idx), getCellValue(asc ? b : a, idx));
table = $(this).closest('table')[0];
tbody = $(table).find('tbody')[0];
elm = $(this)[0];
children = elm.parentNode.children;
Array.from(tbody.querySelectorAll('tr')).sort( comparer(
Array.from(children).indexOf(elm), table.asc = !table.asc))
.forEach(tr => tbody.appendChild(tr) );
}
table.find('thead th').on('click', column_sort);
