You can't divide IF/ELSE instructions into two separate blocks. If you need HTML code to be printed, use echo.
<html>
<?php
function login()
{
// Login function code
}
if (login())
{
echo "<h2>Welcome Administrator</h2>
<a href=\"upload.php\">Upload Files</a>
<br />
<a href=\"points.php\">Edit Points Tally</a>";
}
else
{
echo "Incorrect login details. Please login";
}
?>
Some more HTML code

Yes, Javascript always passes by value, but in an array or object, the value is a reference to it, so you can 'change' the contents.
But, I think you already read it on SO; here you have the documentation you want:
You can use this method to create hidden text field with/without form. If you need form just pass form with object status = true
.
You can also add multiple hidden fields. Use this way:
CustomizePPT.setHiddenFields(
{
"hidden" :
{
'fieldinFORM' : 'thisdata201' ,
'fieldinFORM2' : 'this3' //multiple hidden fields
.
.
.
.
.
'nNoOfFields' : 'nthData'
},
"form" :
{
"status" : "true",
"formID" : "form3"
}
} );
var CustomizePPT = new Object();_x000D_
CustomizePPT.setHiddenFields = function(){ _x000D_
var request = [];_x000D_
var container = '';_x000D_
console.log(arguments);_x000D_

container = document.getElementById("container");_x000D_
}_x000D_
_x000D_
//var container = document.getElementById("container");_x000D_
Object.keys(request).forEach(function(elem)_x000D_

Another way to pass named parameters to Bash... is passing by reference. This is supported as of Bash 4.0
#!/bin/bash
function myBackupFunction(){ # directory options destination filename
local directory="$1" options="$2" destination="$3" filename="$4";
echo "tar cz ${!options} ${!directory} | ssh root@backupserver \"cat > /mnt/${!destination}/${!filename}.tgz\"";
}
declare -A backup=([directory]=".." [options]="..." [destination]="backups" [filename]="backup" );
myBackupFunction backup[directory] backup[options] backup[destination] backup[filename];
An alternative syntax for Bash 4.3 is using a nameref.
Although the nameref is a lot more convenient in that it seamlessly dereferences, some older supported distros still ship an older version, so I won't recommend it quite yet.
Finally, I found a solution to this problem without reinstalling npm and I'm posting it because in future it will help someone, Most of the time this error occurs javascript heap went out of the memory. As the error says itself this is not a problem with npm. Only we have to do is
instead of,
npm run build -prod
extend the javascript memory by following,
node --max_old_space_size=4096 node_modules/@angular/cli/bin/ng build --prod
I faced the same issue and tried various solutions to load the html page from Spring MVC, following solution worked for me
Step-1 in server's web.xml comment these two lines
<!-- <mime-mapping>
<extension>htm</extension>
<mime-type>text/html</mime-type>
</mime-mapping>-->
<!-- <mime-mapping>
<extension>html</extension>
<mime-type>text/html</mime-type>
</mime-mapping>
-->
Step-2 enter following code in application's web xml
<servlet-mapping>
<servlet-name>jsp</servlet-name>
<url-pattern>*.htm</url-pattern>
</servlet-mapping>
Step-3 create a static controller class
@Controller
public class FrontController {
@RequestMapping("/landingPage")
public String getIndexPage() {
return "CompanyInfo";
}
}
Step-4 in the Spring configuration file change the suffix to .htm .htm
Step-5 Rename page as .htm file and store it in WEB-INF and build/start the server
localhost:8080/.../landingPage
I used this one is working for me. One thing needs to be consider that what appcompat
version you are using. I am using appcompat-v7:26.+
so this is working for me.
implementation 'com.android.support:recyclerview-v7:26.+'
import os
rows, columns = os.popen('stty size', 'r').read().split()
uses the 'stty size' command which according to a thread on the python mailing list is reasonably universal on linux. It opens the 'stty size' command as a file, 'reads' from it, and uses a simple string split to separate the coordinates.
Unlike the os.environ["COLUMNS"] value (which I can't access in spite of using bash as my standard shell) the data will also be up-to-date whereas I believe the os.environ["COLUMNS"] value would only be valid for the time of the launch of the python interpreter (suppose the user resized the window since then).
(See answer by @GringoSuave on how to do this on python 3.3+)
Use the below code. For me it is working
jQuery("[id$='hfSpecialty_ids']").focus()
It is a way of generating a valid URL, generally using data already obtained. For instance, using the title of an article to generate a URL.
Ruby implementation
def find_consecutive_1(n)
num = n.to_s(2)
arr = num.split("")
counter = 0
max = 0
arr.each do |x|
if x.to_i==1
counter +=1
else
max = counter if counter > max
counter = 0
end
max = counter if counter > max
end
max
end
puts find_consecutive_1(439)
The '\r'
character is the carriage return, and the carriage return-newline pair is both needed for newline in a network virtual terminal session.
From the old telnet specification (RFC 854) (page 11):
The sequence "CR LF", as defined, will cause the NVT to be positioned at the left margin of the next print line (as would, for example, the sequence "LF CR").
However, from the latest specification (RFC5198) (page 13):
...
In Net-ASCII, CR MUST NOT appear except when immediately followed by either NUL or LF, with the latter (CR LF) designating the "new line" function. Today and as specified above, CR should generally appear only when followed by LF. Because page layout is better done in other ways, because NUL has a special interpretation in some programming languages, and to avoid other types of confusion, CR NUL should preferably be avoided as specified above.
LF CR SHOULD NOT appear except as a side-effect of multiple CR LF sequences (e.g., CR LF CR LF).
So newline in Telnet should always be '\r\n'
but most implementations have either not been updated, or keeps the old '\n\r'
for backwards compatibility.
I assume you have different sized images. I tested this myself, and it works as you describe (always centered, images widths appropriately)
/*CSS*/
div.c-wrapper{
width: 80%; /* for example */
margin: auto;
}
.carousel-inner > .item > img,
.carousel-inner > .item > a > img{
width: 100%; /* use this, or not */
margin: auto;
}
<!--html-->
<div class="c-wrapper">
<div id="carousel-example-generic" class="carousel slide">
<!-- Indicators -->
<ol class="carousel-indicators">
<li data-target="#carousel-example-generic" data-slide-to="0" class="active"></li>
<li data-target="#carousel-example-generic" data-slide-to="1"></li>
<li data-target="#carousel-example-generic" data-slide-to="2"></li>
</ol>
<!-- Wrapper for slides -->
<div class="carousel-inner">
<div class="item active">
<img src="http://placehold.it/600x400">
<div class="carousel-caption">
hello
</div>
</div>
<div class="item">
<img src="http://placehold.it/500x400">
<div class="carousel-caption">
hello
</div>
</div>
<div class="item">
<img src="http://placehold.it/700x400">
<div class="carousel-caption">

</div>
</div>
</div>
<!-- Controls -->
<a class="left carousel-control" href="#carousel-example-generic" data-slide="prev">
<span class="icon-prev"></span>
</a>
<a class="right carousel-control" href="#carousel-example-generic" data-slide="next">

</div>
This creates a "jump" due to variable heights... to solve that, try something like this: Select the tallest image of a list
Or use media-query to set your own fixed height.
use simplejson or cjson for speedups
import simplejson as json
json.loads(obj)
or
cjson.decode(obj)
you don't need to pass any regular expression there. this works just fine..
(function($) {
$(document).ready(function() {
$('#data').click(function(e) {
e.preventDefault();
$.each($("#keywords").val().split("\n"), function(e, element) {
alert(element);
});
});
});
})(jQuery);
I found an other way to achieve this...
Step 1: Put the dialog opening code in a method (Or Function in C).
Step 2: Inside the onClick of yes
(Your positiveButton), call this dialog opening
method recursively if your condition is not satisfied (By using if...else...). Like below :
private void openSave() {
final AlertDialog.Builder builder=new AlertDialog.Builder(Phase2Activity.this);
builder.setTitle("SAVE")
.setIcon(R.drawable.ic_save_icon)
.setPositiveButton("Save", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
if((!editText.getText().toString().isEmpty() && !editText1.getText().toString().isEmpty())){
createPdf(fileName,title,file);
}else {
openSave();
Toast.makeText(Phase2Activity.this, "Some fields are empty.", Toast.LENGTH_SHORT).show();
}
})
.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
}
})
.setCancelable(false)
.create()
.show();
}
But this will make the dialog disappear just for a moment and it will appear again instantly. :)
Just ran into this again (certain I had before and came up with a less-than-satisfying solution).
For a tri-state boolean semantic (for example, using models.NullBooleanField
), this works well:
{% if test.passed|lower == 'false' %} ... {% endif %}
Or if you prefer getting excited over the whole thing...
{% if test.passed|upper == 'FALSE' %} ... {% endif %}
Either way, this handles the special condition where you don't care about the None
(evaluating to False in the if block) or True
case.
I think that this will do the trick:
table{
table-layout: fixed;
width: 300px;
}
Today I filed a JEP draft to OpenJDK about this aliasing feature. I hope they will reconsider it.

Not sure about the (errors="ignore") option but it seems to work for files with strange Unicode characters.

to the EditText in xml and thats all.(If someone still needs to know how to do that with the easy way)
Caution: This answer was written in 2010 and technology moves fast. For a more recent solution, see @ctrl-alt-dileep's answer below.
Depending on your needs, you may wish to try the jQuery touch plugin; you can try an example here. It works fine to drag on my iPhone, whereas jQuery UI Draggable doesn't.
Alternatively, you can try this plugin, though that might require you to actually write your own draggable function.
As a sidenote: Believe it or not, we're hearing increasing buzz about how touch devices such as the iPad and iPhone is causing problems both for websites using :hover/onmouseover functions and draggable content.
If you're interested in the underlying solution for this, it's to use three new JavaScript events; ontouchstart, ontouchmove and ontouchend. Apple actually has written an article about their use, which you can find here. A simplified example can be found here. These events are used in both of the plugins I linked to.
Like @takeshin said .d stands for declaration file for typescript (.ts).
Few points to be clarified before proceeding to answer this post -
If you are thinking if typescript is just syntactic superset, what benefits does it offer - https://basarat.gitbooks.io/typescript/docs/why-typescript.html#the-typescript-type-system
To Answer this post -
As we discussed, typescript is superset of javascript and needs to be transpiled into javascript. So if a library or third party code is written in typescript, it eventually gets converted to javascript which can be used by javascript project but vice versa does not hold true.
For ex -
If you install javascript library -
npm install --save mylib
and try importing it in typescript code -
import * from "mylib";
you will get error.
"Cannot find module 'mylib'."
As mentioned by @Chris, many libraries like underscore, Jquery are already written in javascript. Rather than re-writing those libraries for typescript projects, an alternate solution was needed.
In order to do this, you can provide type declaration file in javascript library named as *.d.ts, like in above case mylib.d.ts. Declaration file only provides type declarations of functions and variables defined in respective javascript file.
Now when you try -
import * from "mylib";
mylib.d.ts gets imported which acts as an interface between javascript library code and typescript project.
As long as you clearly reference the other commit from the empty commit it should be fine. Something like:
Commit message errata for [commit sha1]
[new commit message]
As others have pointed out, this is often preferable to force pushing a corrected commit.
Try using this:
var x:Int!
var xTimesTwo:Int {
get {
return x * 2
}
set {
x = newValue / 2
}
}
This is basically Jack Wu's answer, but the difference is that in Jack Wu's answer his x variable is var x: Int
, in mine, my x variable is like this: var x: Int!
, so all I did was make it an optional type.
Please stick to the semantics of protocol. Use 2xx for successful responses and 4xx , 5xx for error responses - be it your business exceptions or other. Had using 2xx for any response been the intended use case in the protocol, they would not have other status codes in the first place.
After editting the "right" files (all php.ini's). i had still the issue. My solution was:
Adding a System variable: OPENSSL_CONF
the value of OPENSSL_CONF should be the openssl.cnf file of your current php version.
for me it was:
-> Restart WAMP -> should work now
No, CSV doesn't specify any way of tagging comments - they will just be loaded by programs like Excel as additional cells containing text.
The closest you can manage (with CSV being imported into a specific application such as Excel) is to define a special way of tagging comments that Excel will ignore. For Excel, you can "hide" the comment (to a limited degree) by embedding it into a formula. For example, try importing the following csv file into Excel:
=N("This is a comment and will appear as a simple zero value in excel")
John, Doe, 24
You still end up with a cell in the spreadsheet that displays the number 0, but the comment is hidden.
Alternatively, you can hide the text by simply padding it out with spaces so that it isn't displayed in the visible part of cell:
This is a sort-of hidden comment!,
John, Doe, 24
Note that you need to follow the comment text with a comma so that Excel fills the following cell and thus hides any part of the text that doesn't fit in the cell.
Nasty hacks, which will only work with Excel, but they may suffice to make your output look a little bit tidier after importing.
I tried this out for transmitting continuous data (float values converted to string) from my PC (MATLAB) to my phone. But, still my App misreads the delimiter '\n' and still data gets garbled. So, I took the character 'N' as the delimiter rather than '\n' (it could be any character that doesn't occur as part of your data) and I've achieved better transmission speed - I gave just 0.1 seconds delay between transmitting successive samples - with more than 99% data integrity at the receiver i.e. out of 2000 samples (float values) that I transmitted, only 10 were not decoded properly in my application.
My answer in short is: Choose a delimiter other than '\r' or '\n' as these create more problems for real-time data transmission when compared to other characters like the one I've used. If we work more, may be we can increase the transmission rate even more. I hope my answer helps someone!
Here is a sample:
<?php
// Snippet from PHP Share: http://www.phpshare.org
function formatSizeUnits($bytes)
{
if ($bytes >= 1073741824)
{
$bytes = number_format($bytes / 1073741824, 2) . ' GB';
}
elseif ($bytes >= 1048576)
{
$bytes = number_format($bytes / 1048576, 2) . ' MB';
}
elseif ($bytes >= 1024)
{
$bytes = number_format($bytes / 1024, 2) . ' KB';
}
elseif ($bytes > 1)
{
$bytes = $bytes . ' bytes';
}
elseif ($bytes == 1)
{
$bytes = $bytes . ' byte';
}
else

Do which sshpass
in your command line to get the absolute path to sshpass
and replace it in the bash script.
You should also probably do the same with the command
you are trying to run.
The problem might be that it is not finding it.
Due to its folder nesting Windows can’t delete the folder as its name is too long. To solve this, install RimRaf:
npm install rimraf -g
rimraf node_modules
From the Docs:
(function( $ ){
$.fn.myfunction = function() {
alert('hello world');
return this;
};
})( jQuery );
Then you do
$('#my_div').myfunction();
range()
can only work with integers, but dividing with the /
operator always results in a float value:
>>> 450 / 10
45.0
>>> range(450 / 10)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'float' object cannot be interpreted as an integer
Make the value an integer again:
for i in range(int(c / 10)):
or use the //
floor division operator:
for i in range(c // 10):
To answer your main question, you want to use the subplot command. I think changing plt.figure(i)
to plt.subplot(4,4,i+1)
should work.
Yeah, as others have said, there's no convenient 'DELETE FROM my_table ... CASCADE' (or equivalent). To delete non-cascading foreign key-protected child records and their referenced ancestors, your options include:
It's on purpose that circumventing foreign key constraints isn't made convenient, I assume; but I do understand why in particular circumstances you'd want to do it. If it's something you'll be doing with some frequency, and if you're willing to flout the wisdom of DBAs everywhere, you may want to automate it with a procedure.
I came here a few months ago looking for an answer to the "CASCADE DELETE just once" question (originally asked over a decade ago!). I got some mileage out of Joe Love's clever solution (and Thomas C. G. de Vilhena's variant), but in the end my use case had particular requirements (handling of intra-table circular references, for one) that forced me to take a different approach. That approach ultimately became recursively_delete (PG 10.10).
I've been using recursively_delete in production for a while, now, and finally feel (warily) confident enough to make it available to others who might wind up here looking for ideas. As with Joe Love's solution, it allows you to delete entire graphs of data as if all foreign key constraints in your database were momentarily set to CASCADE, but offers a couple additional features:
What worked for me was
<WebBrowser Source="pack://siteoforigin:,,,/StartPage.html" />
from here. I copied StartPage.html to the same output directory as the xaml-file and it loaded it from that relative path.
If you want a UTF8 string, where every byte is correct ('Ö' -> [195, 0] , [150, 0]), you can use the followed:
public static string Utf16ToUtf8(string utf16String)
{
/**************************************************************
* Every .NET string will store text with the UTF16 encoding, *
* known as Encoding.Unicode. Other encodings may exist as *
* Byte-Array or incorrectly stored with the UTF16 encoding. *
* *
* UTF8 = 1 bytes per char *
* ["100" for the ansi 'd'] *
* ["206" and "186" for the russian '?'] *
* *
* UTF16 = 2 bytes per char *
* ["100, 0" for the ansi 'd'] *
* ["186, 3" for the russian '?'] *
* *
* UTF8 inside UTF16 *
* ["100, 0" for the ansi 'd'] *
* ["206, 0" and "186, 0" for the russian '?'] *
* *
* We can use the convert encoding function to convert an *
* UTF16 Byte-Array to an UTF8 Byte-Array. When we use UTF8 *
* encoding to string method now, we will get a UTF16 string. *
* *
* So we imitate UTF16 by filling the second byte of a char *
* with a 0 byte (binary 0) while creating the string. *
**************************************************************/
// Storage for the UTF8 string
string utf8String = String.Empty;
// Get UTF16 bytes and convert UTF16 bytes to UTF8 bytes
byte[] utf16Bytes = Encoding.Unicode.GetBytes(utf16String);
byte[] utf8Bytes = Encoding.Convert(Encoding.Unicode, Encoding.UTF8, utf16Bytes);
// Fill UTF8 bytes inside UTF8 string
for (int i = 0; i < utf8Bytes.Length; i++)
{
// Because char always saves 2 bytes, fill char with 0
byte[] utf8Container = new byte[2] { utf8Bytes[i], 0 };
utf8String += BitConverter.ToChar(utf8Container, 0);
}
// Return UTF8
return utf8String;
}
In my case the DLL request is a UTF8 string too, but unfortunately the UTF8 string must be interpreted with UTF16 encoding ('Ö' -> [195, 0], [19, 32]). So the ANSI '–' which is 150 has to be converted to the UTF16 '–' which is 8211. If you have this case too, you can use the following instead:
public static string Utf16ToUtf8(string utf16String)
{
// Get UTF16 bytes and convert UTF16 bytes to UTF8 bytes
byte[] utf16Bytes = Encoding.Unicode.GetBytes(utf16String);
byte[] utf8Bytes = Encoding.Convert(Encoding.Unicode, Encoding.UTF8, utf16Bytes);
// Return UTF8 bytes as ANSI string
return Encoding.Default.GetString(utf8Bytes);
}
Or the Native-Method:
[DllImport("kernel32.dll")]
private static extern Int32 WideCharToMultiByte(UInt32 CodePage, UInt32 dwFlags, [MarshalAs(UnmanagedType.LPWStr)] String lpWideCharStr, Int32 cchWideChar, [Out, MarshalAs(UnmanagedType.LPStr)] StringBuilder lpMultiByteStr, Int32 cbMultiByte, IntPtr lpDefaultChar, IntPtr lpUsedDefaultChar);
public static string Utf16ToUtf8(string utf16String)
{
Int32 iNewDataLen = WideCharToMultiByte(Convert.ToUInt32(Encoding.UTF8.CodePage), 0, utf16String, utf16String.Length, null, 0, IntPtr.Zero, IntPtr.Zero);
if (iNewDataLen > 1)
{
StringBuilder utf8String = new StringBuilder(iNewDataLen);
WideCharToMultiByte(Convert.ToUInt32(Encoding.UTF8.CodePage), 0, utf16String, -1, utf8String, utf8String.Capacity, IntPtr.Zero, IntPtr.Zero);
return utf8String.ToString();
}
else
{
return String.Empty;
}
}
If you need it the other way around, see Utf8ToUtf16. Hope I could be of help.
You could subscribe for the onkeypress event:
<input type="text" class="textfield" value="" id="extra7" name="extra7" onkeypress="return isNumber(event)" />
and then define the isNumber
function:
function isNumber(evt) {
evt = (evt) ? evt : window.event;
var charCode = (evt.which) ? evt.which : evt.keyCode;
if (charCode > 31 && (charCode < 48 || charCode > 57)) {
return false;
}
return true;
}
You can see it in action here.
Well, even the accepted answer does not exactly output what op has asked for. It outputs the JSON string but with "
characters escaped. So, although might be a little late, I am answering hopeing it will help people! Here is how I do it:
StringWriter writer = new StringWriter();
JsonGenerator jgen = new JsonFactory().createGenerator(writer);
jgen.setCodec(new ObjectMapper());
jgen.writeObject(object);
jgen.close();
System.out.println(writer.toString());
private void buttonHook_Click(object sender, EventArgs e)
{
// Hooks only into specified Keys (here "A" and "B").
// (***) Use this constructor
_globalKeyboardHook = new GlobalKeyboardHook(new Keys[] { Keys.A, Keys.B });
// Hooks into all keys.
// (***) Or this - not both
_globalKeyboardHook = new GlobalKeyboardHook();
_globalKeyboardHook.KeyboardPressed += OnKeyPressed;
}
And then is working fine.
To make this work on Ubuntu Linux:
I installed the Ubuntu package ruby-json:
apt-get install ruby-json
I wrote the script in ${HOME}/rubybin/jsonDEMO
$HOME/.bashrc
included:
${HOME}/rubybin:${PATH}
(On this occasion I also typed the above on the bash command line.)
Then it worked when I entered on the command line:
jsonDemo
You could type "prop" and then press tab twice. That will generate the following.
public TYPE Type { get; set; }
Then you change "TYPE" and "Type":
public string myString {get; set;}
You can also get the full property typing "propfull" and then tab twice. That would generate the field and the full property.
private int myVar;
public int MyProperty
{
get { return myVar;}
set { myVar = value;}
}
navigator.clipboard doesn't work over http connection according to their document. So you can check if it's coming undefined and use document.execCommand('copy') instead, this solution should cover almost all the browsers
const defaultCopySuccessMessage = 'ID copied!'
const CopyItem = (props) => {
const { copySuccessMessage = defaultCopySuccessMessage, value } = props
const [showCopySuccess, setCopySuccess] = useState(false)
function fallbackToCopy(text) {

The main difference between EBS and EFS is that EBS is only accessible from a single EC2 instance in your particular AWS region, while EFS allows you to mount the file system across multiple regions and instances.
Finally, Amazon S3 is an object store good at storing vast numbers of backups or user files.
I want to select the distinct values from one column 'GrondOfLucht' but they should be sorted in the order as given in the column 'sortering'. I cannot get the distinct values of just one column using
Select distinct GrondOfLucht,sortering
from CorWijzeVanAanleg
order by sortering
It will also give the column 'sortering' and because 'GrondOfLucht' AND 'sortering' is not unique, the result will be ALL rows.
use the GROUP to select the records of 'GrondOfLucht' in the order given by 'sortering
SELECT GrondOfLucht
FROM dbo.CorWijzeVanAanleg
GROUP BY GrondOfLucht, sortering
ORDER BY MIN(sortering)
You need to implement your own Comparator
, and then use it: for example
Arrays.sort(persons, new PersonComparator());
Your Comparator could look a bit like this:
public class PersonComparator implements Comparator<? extends Person> {
public int compare(Person p1, Person p2) {
int nameCompare = p1.name.compareToIgnoreCase(p2.name);
if (nameCompare != 0) {
return nameCompare;
} else {
return Integer.valueOf(p1.age).compareTo(Integer.valueOf(p2.age));
}
}
}
The comparator first compares the names, if they are not equals it returns the result from comparing them, else it returns the compare result when comparing the ages of both persons.
This code is only a draft: because the class is immutable you could think of building an singleton of it, instead creating a new instance for each sorting.
diff a1.txt a2.txt | grep '> ' | sed 's/> //' > a3.txt
I tried almost all the answers in this thread, but none was complete. After few trails above one worked for me. diff will give you difference but with some unwanted special charas. where you actual difference lines starts with '> '. so next step is to grep lines starts with '> 'and followed by removing the same with sed.
int myInt = (int) myFloat;
Worked fine for me.
int myInt = [[NSNumber numberWithFloat:myFloat] intValue];
Well, that is one option. If you like the detour, I could think of some using NSString. Why easy, when there is a complicated alternative? :)
If you want to refresh the page if there is no activity then you need to figure out how to define activity. Let's say we refresh the page every minute unless someone presses a key or moves the mouse. This uses jQuery for event binding:
<script>
var time = new Date().getTime();
$(document.body).bind("mousemove keypress", function(e) {
time = new Date().getTime();
});
function refresh() {
if(new Date().getTime() - time >= 60000)
window.location.reload(true);
else
setTimeout(refresh, 10000);
}
setTimeout(refresh, 10000);
</script>
Replace
import { Router, Route, Link, browserHistory } from 'react-router';
With
import { BrowserRouter as Router, Route } from 'react-router-dom';
It will start working. It is because react-router-dom exports BrowserRouter
I figured out myself.
cmp
calls ComputeBetasAndNuHat
which returns a list which has objective
as minusloglik
So I can change the function cmp
to get this value.
targetList = list1.Concat(list2).ToList();
It's working fine I think so. As previously said, Concat returns a new sequence and while converting the result to List, it does the job perfectly.
I think that the main difference is that Marshalling supposedly also involves the codebase. In other words, you would not be able to marshal and unmarshal an object into a state-equivalent instance of a different class. .
Serialization just means that you can store the object and reobtain an equivalent state, even if it is an instance of another class.
That being said, they are typically synonyms.
Ok, first launch an ipython shell

Now, we can watch the GPU memory usage in a console using the following command:
# realtime update for every 2s
$ watch -n 2 nvidia-smi
Since we've only import
ed TensorFlow but have not used any GPU yet, the usage stats will be:
Notice how the GPU memory usage is very less (~ 700MB); Sometimes the GPU memory usage might even be as low as 0 MB.
Now, let's load the GPU in our code. As indicated in tf documentation
, do:
In [2]: sess = tf.Session(config=tf.ConfigProto(log_device_placement=True))
Now, the watch stats should show an updated GPU usage memory as below:
Observe now how our Python process from the ipython shell is using ~ 7 GB of the GPU memory.
P.S. You can continue watching these stats as the code is running, to see how intense the GPU usage is over time.
On the same note, if your server supports both http
and https
you can connect using:
var socket = io.connect('//localhost');
to auto detect the browser scheme and connect using http/https accordingly. when in https, the transport will be secured by default, as connecting using
var socket = io.connect('https://localhost');
will use secure web sockets - wss://
(the {secure: true}
is redundant).
for more information on how to serve both http and https easily using the same node server check out this answer.

It seems the answers here do not support an enterprise use case where a Nexus server has multiple users and has project-based isolation (protection) based on user id ALONG with using an automated build (CI) system like Jenkins. You would not be able to create a settings.xml file to satisfy the different user ids needed for different projects. I am not sure how to solve this, except by opening Nexus up to anonymous access for reading repositories, unless the projects could store a project-specific generic user id in their pom.xml.
Just an addition to the previous answers. Let's not forget that when dealing with real data there might be null values, so it's useful to also include those in the counting by using the option dropna=False

The accepted answer has the drawback that it doesn't take into consideration that a database can be locked by a connection that is executing a query that involves tables in a database other than the one connected to.
This can be the case if the server instance has more than one database and the query directly or indirectly (for example through synonyms) use tables in more than one database etc.
I therefore find that it sometimes is better to use syslockinfo to find the connections to kill.
My suggestion would therefore be to use the below variation of the accepted answer from AlexK:
USE [master];
DECLARE @kill varchar(8000) = '';
SELECT @kill = @kill + 'kill ' + CONVERT(varchar(5), req_spid) + ';'
FROM master.dbo.syslockinfo
WHERE rsc_type = 2
AND rsc_dbid = db_id('MyDB')
EXEC(@kill);
You can do it by using below CSS:
table {
width: 100%;
table-layout: fixed;
}
th, td {
overflow: hidden;
width: 200px;
text-overflow: ellipsis;
white-space: nowrap;
}

tl;dr the "standards" are a hodge-podge mess; it depends who you ask!
Overall, there appears to be no MIME type image/jpg
. Yet, in practice, nearly all software handles image files named "*.jpg
" just fine.
This particular topic is confusing because the varying association of file name extension associated to a MIME type depends which organization created the table of file name extensions to MIME types. In other words, file name extension .jpg
could be many different things.
For example, here are three "complete lists" and one RFC that with varying JPEG Image format file name extensions and the associated MIME types.
.jfif
, .jfif-tbnl
, .jpe
, .jpeg
, .jpg
? image/jpeg
.jfif
, .jpe
, .jpeg
, .jpg
? image/pjpeg
.jpeg
, .jpg
? image/jpeg
.jpeg
, .jpg
? image/x-citrix-jpeg
.pjpeg
? image/pjpeg
jpg
not mentionedjpeg
? see RFC 2045 (no mention), see RFC 2046 ? image/jpeg
13JPEG
? video/JPEG
jpeg2000
? video/jpeg2000
jpm
? image/jpm
(JPEG 2000)jpx
? image/jpx
(JPEG 2000)vnd.sealedmedia.softseal.jpg
? image/vnd.sealedmedia.softseal.jpg
These "complete lists" and RFC do not have MIME type image/jpg
! But for MIME type image/jpeg
some lists do have varying file name extensions (.jpeg
, .jpg
, …). Other lists do not mention image/jpeg
.
Also, there are different types of JPEG Image formats (e.g. Progressive JPEG Image format, JPEG 2000, etcetera) and "JPEG Extensions" that may or may not overlap in file name extension and declared MIME type.
Another confusing thing is RFC 3745 does not appear to match IANA Media Types yet the same RFC is supposed to inform the IANA Media Types document. For example, in RFC 3745 .jpf
is preferred file extension for image/jpx
but in IANA Media Types the name jpf
is not present (and that IANA document references RFC 3745!).
Another confusing thing is IANA Media Types lists "names" but does not list "file name extensions". This is on purpose, but confuses the endeavor of mapping file name extensions to MIME types.
Another confusing thing: is it "mime", or "MIME", or "MIME type", or "mime type", or "mime/type", or "media type"?
The most official seeming document by IANA is surprisingly inadequate. No MIME type is registered for file extension .jpg
yet there exists the odd vnd.sealedmedia.softseal.jpg
. File extension.JPEG
is only known as a video
type while file extension .jpeg
is an image type (when did lowercase and uppercase letters start mattering!?). At the same time, jpeg2000
is type video
yet RFC 3745 considers JPEG 2000 an image
type! The IANA list seems to cater to company-specific jpeg formats (e.g. vnd.sealedmedia.softseal.jpg
).
Because of the prior confusions, it is difficult to find an industry-accepted canonical document that maps file name extensions to MIME types, particularly for the JPEG Image File Format.

I face same issue with sts 3.8.4, so I tried different settings but not luck, I reinstall jdk again n tried but same problem. Finally I downloaded sts 3.8.2 n it runs with out any issue. Using windows 8, 64 bit os. thanks
for /f "tokens=* delims= " %%f in (myfile) do
This reads a file line-by-line, removing leading spaces (thanks, jeb).
set line=%%f
sets then the line
variable to the line just read and
call :procesToken
calls a subroutine that does something with the line
:processToken
is the start of the subroutine mentioned above.
for /f "tokens=1* delims=/" %%a in ("%line%") do
will then split the line at /
, but stopping tokenization after the first token.
echo Got one token: %%a
will output that first token and
set line=%%b
will set the line
variable to the rest of the line.
if not "%line%" == "" goto :processToken
And if line
isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.
Force popen
to not continue until all output is read by doing:

My contribution based on the algorithm for fast exponentiation.
/**
* Repeats the given {@link String} n times.
*
* @param str
* the {@link String} to repeat.
* @param n
* the repetition count.
* @throws IllegalArgumentException
* when the given repetition count is smaller than zero.
* @return the given {@link String} repeated n times.
*/
public static String repeat(String str, int n) {
if (n < 0)
throw new IllegalArgumentException(
"the given repetition count is smaller than zero!");
else if (n == 0)
return "";
else if (n == 1)
return str;
else if (n % 2 == 0) {
String s = repeat(str, n / 2);
return s.concat(s);
} else
return str.concat(repeat(str, n - 1));
}
I tested the algorithm against two other approaches:
String.concat()
to concatenate stringStringBuilder
Test code (concatenation using a for loop and String.concat()
becomes to slow for large n
, so I left it out after the 5th iteration).
/**
* Test the string concatenation operation.
*
* @param args
*/
public static void main(String[] args) {
long startTime;
String str = " ";
int n = 1;
for (int j = 0; j < 9; ++j) {
n *= 10;
System.out.format("Performing test with n=%d\n", n);
startTime = System.currentTimeMillis();
StringUtil.repeat(str, n);
System.out
.format("\tStringUtil.repeat() concatenation performed in %d milliseconds\n",
System.currentTimeMillis() - startTime);
if (j <5) {
startTime = System.currentTimeMillis();
String string = "";
for (int i = 0; i < n; ++i)
string = string.concat(str);
System.out
.format("\tString.concat() concatenation performed in %d milliseconds\n",
System.currentTimeMillis() - startTime);
} else
System.out
.format("\tString.concat() concatenation performed in x milliseconds\n");
startTime = System.currentTimeMillis();
StringBuilder b = new StringBuilder();
for (int i = 0; i < n; ++i)
b.append(str);
b.toString();
System.out
.format("\tStringBuilder.append() concatenation performed in %d milliseconds\n",
System.currentTimeMillis() - startTime);
}
}

Conclusion:
n
- use the recursive approachn
- for loop has sufficient speedI think that you could use a POST or PATCH method to handle this since they typically design for this.
Using a POST
method is typically used to add an element when used on list resource but you can also support several actions for this method. See this answer: How to Update a REST Resource Collection. You can also support different representation formats for the input (if they correspond to an array or a single elements).
In the case, it's not necessary to define your format to describe the update.
Using a PATCH
method is also suitable since corresponding requests correspond to a partial update. According to RFC5789 (http://tools.ietf.org/html/rfc5789):
Several applications extending the Hypertext Transfer Protocol (HTTP) require a feature to do partial resource modification. The existing HTTP PUT method only allows a complete replacement of a document. This proposal adds a new HTTP method, PATCH, to modify an existing HTTP resource.
In the case, you have to define your format to describe the partial update.
I think that in this case, POST
and PATCH
are quite similar since you don't really need to describe the operation to do for each element. I would say that it depends on the format of the representation to send.
The case of PUT
is a bit less clear. In fact, when using a method PUT
, you should provide the whole list. As a matter of fact, the provided representation in the request will be in replacement of the list resource one.
You can have two options regarding the resource paths.
In this case, you need to explicitely provide the link of docs with a binder in the representation you provide in the request.
Here is a sample route for this /docs
.
The content of such approach could be for method POST
:
[
{ "doc_number": 1, "binder": 4, (other fields in the case of creation) },
{ "doc_number": 2, "binder": 4, (other fields in the case of creation) },
{ "doc_number": 3, "binder": 5, (other fields in the case of creation) },
(...)
]
In addition you could also consider to leverage sub routes to describe the link between docs and binders. The hints regarding the association between a doc and a binder doesn't have now to be specified within the request content.
Here is a sample route for this /binder/{binderId}/docs
. In this case, sending a list of docs with a method POST
or PATCH
will attach docs to the binder with identifier binderId
after having created the doc if it doesn't exist.
The content of such approach could be for method POST
:
[
{ "doc_number": 1, (other fields in the case of creation) },
{ "doc_number": 2, (other fields in the case of creation) },
{ "doc_number": 3, (other fields in the case of creation) },
(...)
]
Regarding the response, it's up to you to define the level of response and the errors to return. I see two levels: the status level (global level) and the payload level (thinner level). It's also up to you to define if all the inserts / updates corresponding to your request must be atomic or not.
In this case, you can leverage the HTTP status. If everything goes well, you get a status 200
. If not, another status like 400
if the provided data aren't correct (for example binder id not valid) or something else.
In this case, a status 200
will be returned and it's up to the response representation to describe what was done and where errors eventually occur. ElasticSearch has an endpoint in its REST API for bulk update. This could give you some ideas at this level: http://www.elasticsearch.org/guide/en/elasticsearch/guide/current/bulk.html.
You can also implement an asynchronous processing to handle the provided data. In this case, the HTTP status returns will be 202
. The client needs to pull an additional resource to see what happens.
Before finishing, I also would want to notice that the OData specification addresses the issue regarding relations between entities with the feature named navigation links. Perhaps could you have a look at this ;-)

As an additional info to Joey's answer, which isn't described in the help of set /?

%~0
expands to the name of the own batch, exactly as it was typed.
So if you start your batch it will be expanded as
%~0 - mYbAtCh
%~n0 - mybatch
%~nx0 - mybatch.bat
But there is one exception, expanding in a subroutine could fail
echo main- %~0
call :myFunction
exit /b
:myFunction
echo func - %~0
echo func - %~n0
exit /b
This results to
main - myBatch
Func - :myFunction
func - mybatch
In a function %~0
expands always to the name of the function, not of the batch file.
But if you use at least one modifier it will show the filename again!

The answer above with spark-csv is correct but there is an issue - the library creates several files based on the data frame partitioning. And this is not what we usually need. So, you can combine all partitions to one:
df.coalesce(1).
write.
format("com.databricks.spark.csv").
option("header", "true").
save("myfile.csv")
and rename the output of the lib (name "part-00000") to a desire filename.

Sorry this isn't complete because I can't test it here, but it may get you off in the right direction. I'm translating from something I use that makes a similar query:
select mt.section, mt1.count as Active, mt2.count as Inactive
from mytable mt
left join (select section, count from mytable where status='Active')mt1
on mt.section = mt1.section
left join (select section, count from mytable where status='Inactive')mt2
on mt.section = mt2.section
group by mt.section,
mt1.count,
mt2.count
order by mt.section asc;
The code I'm working from is:
select m.typeID, m1.highBid, m2.lowAsk, m1.highBid - m2.lowAsk as diff, 100*(m1.highBid - m2.lowAsk)/m2.lowAsk as diffPercent
from mktTrades m
left join (select typeID,MAX(price) as highBid from mktTrades where bid=1 group by typeID)m1
on m.typeID = m1.typeID
left join (select typeID,MIN(price) as lowAsk from mktTrades where bid=0 group by typeID)m2
on m1.typeID = m2.typeID
group by m.typeID,
m1.highBid,
m2.lowAsk
order by diffPercent desc;
which will return a typeID, the highest price bid and the lowest price asked and the difference between the two (a positive difference would mean something could be bought for less than it can be sold).
og_date = "2012-10-01";
console.log(og_date); // => "2012-10-01"
console.log(og_date.split('-')); // => [ '2012', '10', '01' ]
og_date.value
would only work if the date were stored as a property on the og_date object.
Such as: var og_date = {}; og_date.value="2012-10-01";
In that case, your original console.log would work.

json.loads()
takes a JSON encoded string, not a filename. You want to use json.load()
(no s
) instead and pass in an open file object:
with open('/Users/JoshuaHawley/clean1.txt') as jsonfile:
data = json.load(jsonfile)
The open()
command produces a file object that json.load()
can then read from, to produce the decoded Python object for you. The with
statement ensures that the file is closed again when done.
The alternative is to read the data yourself and then pass it into json.loads()
.
var firstObjectsOfValues = (from d in dic select d.Value[0].ComponentValue("Dep"));
You also need to install software-properties-common for add-apt-repository to work. so it will be
sudo apt-get purge nodejs npm
sudo apt-get install -y python-software-properties python g++ make software-properties-common
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs
you need RequestOptions
let headers = new Headers({'Content-Type': 'application/json'});
headers.append('Authorization','Bearer ')
let options = new RequestOptions({headers: headers});
return this.http.post(APIname,body,options)
.map(this.extractData)
.catch(this.handleError);

One-liner solution here:
var1 = locals().get("var1", "default value")
Instead of having NameError
, this solution will set var1
to default value
if var1
hasn't been defined yet.
Here's how it looks like in Python interactive shell:
>>> var1
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'var1' is not defined
>>> var1 = locals().get("var1", "default value 1")
>>> var1
'default value 1'
>>> var1 = locals().get("var1", "default value 2")
>>> var1
'default value 1'
>>>

Quickest way:
if(IntPtr.Size == 8) {
// 64 bit machine
} else if(IntPtr.Size == 4) {
// 32 bit machine
}
Note: this is very direct and works correctly on 64-bit only if the program does not force execution as a 32-bit process (e.g. through <Prefer32Bit>true</Prefer32Bit>
in the project settings).
I would open another terminal on your laptop and do the scp from there, since you already know how to set that connection up.
scp username@remotecomputer:/path/to/file/you/want/to/copy where/to/put/file/on/laptop
The username@remotecomputer
is the same string you used with ssh initially.
Typing /**

I just created a subclass of UILabel to specially address such use cases. You can add multiple links easily and define different handlers for them. It also supports highlighting the pressed link when you touch down for touch feedback. Please refer to https://github.com/null09264/FRHyperLabel.
In your case, the code may like this:
FRHyperLabel *label = [FRHyperLabel new];
NSString *string = @"This morph was generated with Face Dancer, Click to view in the app store.";
NSDictionary *attributes = @{NSFontAttributeName: [UIFont preferredFontForTextStyle:UIFontTextStyleHeadline]};
label.attributedText = [[NSAttributedString alloc]initWithString:string attributes:attributes];
[label setLinkForSubstring:@"Face Dancer" withLinkHandler:^(FRHyperLabel *label, NSString *substring){
[[UIApplication sharedApplication] openURL:aURL];
}];
Sample Screenshot (the handler is set to pop an alert instead of open a url in this case)
The Constructor is executed when the class is instantiated. It has nothing do with the angular. It is the feature of Javascript and Angular does not have the control over it
The ngOnInit is Angular specific and is called when the Angular has initialized the component with all its input properties
The @Input properties are available under the ngOnInit lifecycle hook. This will help you to do some initialization stuff like getting data from the back-end server etc to display in the view
@Input properties are shows up as undefined inside the constructor
The apply
function takes two arguments; the object this
will be binded to, and the arguments, represented with an array.
some_func = function (a, b) { return b }
some_func.apply(obj, ["arguments", "are", "here"])
// "are"
For AspNetCore, it looks like this:

I wrote this method to handle UTF8 arrays and JSON problems. It works fine with array (simple and multidimensional).
/**
* Encode array from latin1 to utf8 recursively
* @param $dat
* @return array|string
*/
public static function convert_from_latin1_to_utf8_recursively($dat)
{
if (is_string($dat)) {
return utf8_encode($dat);
} elseif (is_array($dat)) {
$ret = [];
foreach ($dat as $i => $d) $ret[ $i ] = self::convert_from_latin1_to_utf8_recursively($d);
return $ret;
} elseif (is_object($dat)) {
foreach ($dat as $i => $d) $dat->$i = self::convert_from_latin1_to_utf8_recursively($d);
return $dat;
} else {
return $dat;
}
}
// Sample use
// Just pass your array or string and the UTF8 encode will be fixed
$data = convert_from_latin1_to_utf8_recursively($data);
ES6 (ECMAScript 2015) Version:
const counts = [4, 9, 15, 6, 2];
const goal = 5;
const output = counts.reduce((prev, curr) => Math.abs(curr - goal) < Math.abs(prev - goal) ? curr : prev);
console.log(output);

For reusability you can wrap in a curry function that supports placeholders (http://ramdajs.com/0.19.1/docs/#curry or https://lodash.com/docs#curry). This gives lots of flexibility depending on what you need:
const getClosest = _.curry((counts, goal) => {
return counts.reduce((prev, curr) => Math.abs(curr - goal) < Math.abs(prev - goal) ? curr : prev);
});
const closestToFive = getClosest(_, 5);
const output = closestToFive([4, 9, 15, 6, 2]);
console.log(output);

You probably want to run git difftool origin/master...
. that should show the unified diff of what is on your current branch that is not on the origin/master branch yet and display it in the graphical diff tool of your choice. To be most up-to-date, run git fetch
first.
You could also do something like:
String str = "a + b - c * d / e < f > g >= h <= i == j";
String[] arr = str.split("(?<=\\G(\\w+(?!\\w+)|==|<=|>=|\\+|/|\\*|-|(<|>)(?!=)))\\s*");
It handles white spaces and words of variable length and produces the array:
[a, +, b, -, c, *, d, /, e, <, f, >, g, >=, h, <=, i, ==, j]
You should write :
if (self.a != 0) and (self.b != 0) :
"&
" is the bit wise operator and does not suit for boolean operations. The equivalent of "&&
" is "and" in Python.
A shorter way to check what you want is to use the "in" operator :
if 0 not in (self.a, self.b) :
You can check if anything is part of a an iterable with "in", it works for :
"foo" in ("foo", 1, c, etc)
will return true"foo" in ["foo", 1, c, etc]
will return true"a" in "ago"
will return true"foo" in {"foo" : "bar"}
will return trueAs an answer to the comments :
Yes, using "in" is slower since you are creating an Tuple object, but really performances are not an issue here, plus readability matters a lot in Python.
For the triangle check, it's easier to read :
0 not in (self.a, self.b, self.c)
Than
(self.a != 0) and (self.b != 0) and (self.c != 0)
It's easier to refactor too.
Of course, in this example, it really is not that important, it's very simple snippet. But this style leads to a Pythonic code, which leads to a happier programmer (and losing weight, improving sex life, etc.) on big programs.
Simply,
$res = (object)array("success"=>false); // $res->success = bool(false);
Or you could instantiate classes with:
$res = (object)array(); // object(stdClass) -> recommended
$res = (object)[]; // object(stdClass) -> works too
$res = new \stdClass(); // object(stdClass) -> old method
and fill values with:
$res->success = !!0; // bool(false)
$res->success = false; // bool(false)
$res->success = (bool)0; // bool(false)

I agree with Bryan's answer
if I do
cell.isUserInteractionEnabled = false
then the subviews within the cell won't be user interacted.
On the other site, setting
cell.selectionStyle = .none
will trigger the didSelect method despite not updating the selection color.
Using willSelectRowAt is the way I solved my problem. Example:
func tableView(_ tableView: UITableView, willSelectRowAt indexPath: IndexPath) -> IndexPath? {
if indexPath.section == 0{
if indexPath.row == 0{
return nil
}
}
else if indexPath.section == 1{
if indexPath.row == 0{
return nil
}
}
return indexPath
}
Try:
if (isset($_FILES['uploaded_file']) &&
$_FILES['uploaded_file']['error'] == UPLOAD_ERR_OK) {
$mail->AddAttachment($_FILES['uploaded_file']['tmp_name'],
$_FILES['uploaded_file']['name']);
}
Basic example can also be found here.
The function definition for AddAttachment
is:
public function AddAttachment($path,
$name = '',
$encoding = 'base64',
$type = 'application/octet-stream')
You can create a unix timestamp date from a date this way:
NSTimeInterval timestamp = [[NSDate date] timeIntervalSince1970];
cd $(dirname $(readlink -f $0))
To show vertical scroll bar in your div you need to add
height: 100px;
overflow-y : scroll;
or
height: 100px;
overflow-y : auto;
Create am array and put inside the first, in this case i get data from JSON response
$.getJSON('/Tool/GetAllActiviesStatus/',
var dataFC = new Array();
function (data) {
for (var i = 0; i < data.Result.length; i++) {
var serie = new Array(data.Result[i].FUNCAO, data.Result[i].QT, true, true);
dataFC.push(serie);
});
In my case i had two declaration of
<?xml version="1.0" encoding="utf-8"?>
in my vector drawable icon
all i had to do was delete one
Add this at your TODO point:

Here is what I use:

class BackgroundLocationManager :NSObject, CLLocationManagerDelegate {
static let instance = BackgroundLocationManager()
static let BACKGROUND_TIMER = 150.0 // restart location manager every 150 seconds

previousTaskId = UIBackgroundTaskInvalid
}
timer = NSTimer.scheduledTimerWithTimeInterval(BackgroundLocationManager.BACKGROUND_TIMER, target: self, selector: #selector(self.restart),userInfo: nil, repeats: false)

}
I start the tracking in AppDelegate like that:
BackgroundLocationManager.instance.start()
Websockets use sockets in their implementation. Websockets are based on a standard protocol (now in final call, but not yet final) that defines a connection "handshake" and message "frame." The two sides go through the handshake procedure to mutually accept a connection and then use the standard message format ("frame") to pass messages back and forth.
I'm developing a framework that will allow you to communicate directly machine to machine with installed software. It might suit your purpose. You can follow my blog if you wish: http://highlevellogic.blogspot.com/2011/09/websocket-server-demonstration_26.html
Not the greatest, but this should work:
sed -i 'Ns/.*/replacement-line/' file.txt
where N
should be replaced by your target line number. This replaces the line in the original file. To save the changed text in a different file, drop the -i
option:
sed 'Ns/.*/replacement-line/' file.txt > new_file.txt
SIMPLE
It's a prefix to indicate the number is in hexadecimal rather than in some other base. The C programming language uses it to tell compiler.
Example :
0x6400
translates to 6*16^3 + 4*16^2 + 0*16^1 +0*16^0 = 25600.
When compiler reads 0x6400
, It understands the number is hexadecimal with the help of 0x term. Usually we can understand by (6400)16 or (6400)8
or any base ..
Hope Helped in some way.
Good day,
I think in this case they are the same, but here is an example where order matters:
const int* cantChangeTheData;
int* const cantChangeTheAddress;
If you are on a OS X, this probably has nothing to do with the sed command. On the OSX version of sed
, the -i
option expects an extension
argument so your command is actually parsed as the extension
argument and the file path is interpreted as the command code.
Try adding the -e
argument explicitly and giving ''
as argument to -i
:
find ./ -type f -exec sed -i '' -e "s/192.168.20.1/new.domain.com/" {} \;
See this.
Two options:
for (let item in MotifIntervention) {
if (isNaN(Number(item))) {
console.log(item);
}
}
Or
Object.keys(MotifIntervention).filter(key => !isNaN(Number(MotifIntervention[key])));
String enums look different than regular ones, for example:
enum MyEnum {
A = "a",
B = "b",
C = "c"
}
Compiles into:
var MyEnum;
(function (MyEnum) {
MyEnum["A"] = "a";
MyEnum["B"] = "b";
MyEnum["C"] = "c";
})(MyEnum || (MyEnum = {}));
Which just gives you this object:
{
A: "a",
B: "b",
C: "c"
}
You can get all the keys (["A", "B", "C"]
) like this:
Object.keys(MyEnum);
And the values (["a", "b", "c"]
):
Object.keys(MyEnum).map(key => MyEnum[key])
Or using Object.values():
Object.values(MyEnum)
<c:set var="baseURL" value="${pageContext.request.requestURL.substring(0, pageContext.request.requestURL.length() - pageContext.request.requestURI.length())}${pageContext.request.contextPath}/" />
<head>
<base href="${baseURL}" />
To set flashdata you need to redirect controller function
$this->session->set_flashdata('message_name', 'This is test message');
//redirect to some function
redirect("controller/function_name");
//echo in view or controller
$this->session->flashdata('message_name');
since you set your itemsource to your collection, your textbox is tied to each individual item in that collection. the selected item property is useful in this scenario if you were trying to do a master-detail form, having 2 listboxes. you would bind the second listbox's itemsource to the child collection of rules. in otherwords the selected item alerts outside controls that your source has changed, internal controls(those inside your datatemplate already are aware of the change.
and to answer your question yes in most circumstances setting the itemsource is the same as setting the datacontext of the control.
I discovered a neat workaround for mingw32 (i.e. for those of you using the version of bash which is installed by git-scm.com on windows):
code () { VSCODE_CWD="$PWD" cmd //c code $* ;}
If you don't care about the compatibility with older IE versions (< 8), you could make a custom jQuery plugin and then call it on the overflowing element.
This solution has an advantage over the one Šime Vidas proposed, as it doesn't overwrite the scrolling behavior - it just blocks it when appropriate.
$.fn.isolatedScroll = function() {
this.bind('mousewheel DOMMouseScroll', function (e) {
var delta = e.wheelDelta || (e.originalEvent && e.originalEvent.wheelDelta) || -e.detail,
bottomOverflow = this.scrollTop + $(this).outerHeight() - this.scrollHeight >= 0,
topOverflow = this.scrollTop <= 0;
if ((delta < 0 && bottomOverflow) || (delta > 0 && topOverflow)) {
e.preventDefault();
}
});
return this;
};
$('.scrollable').isolatedScroll();
Since the question is not restricted to Android Studio, So I am giving the path for Visual Studio 2015 (worked for Xamarin).
Special Thanks to other answerers of this question.
index
and find
Next to the find
method there is as well index
. find
and index
both yield the same result: returning the position of the first occurrence, but if nothing is found index
will raise a ValueError
whereas find
returns -1
. Speedwise, both have the same benchmark results.
s.find(t) #returns: -1, or index where t starts in s
s.index(t) #returns: Same as find, but raises ValueError if t is not in s
rfind
and rindex
:In general, find and index return the smallest index where the passed-in string starts, and
rfind
andrindex
return the largest index where it starts Most of the string searching algorithms search from left to right, so functions starting withr
indicate that the search happens from right to left.
So in case that the likelihood of the element you are searching is close to the end than to the start of the list, rfind
or rindex
would be faster.
s.rfind(t) #returns: Same as find, but searched right to left
s.rindex(t) #returns: Same as index, but searches right to left

this works with "NA"
not for NA
comments = c("no","yes","NA")
for (l in 1:length(comments)) {
#if (!is.na(comments[l])) print(comments[l])
if (comments[l] != "NA") print(comments[l])
}
This resolved issue for me.

I'm sure this question should have a more general answer with some reusable code that works with cookies as key-value pairs.
This snippet is taken from MDN and probably is trustable. This is UTF-safe object for work with cookies:
var docCookies = {
getItem: function (sKey) {
return decodeURIComponent(document.cookie.replace(new RegExp("(?:(?:^|.*;)\\s*" + encodeURIComponent(sKey).replace(/[\-\.\+\*]/g, "\\$&") + "\\s*\\=\\s*([^;]*).*$)|^.*$"), "$1")) || null;
},
setItem: function (sKey, sValue, vEnd, sPath, sDomain, bSecure) {
if (!sKey || /^(?:expires|max\-age|path|domain|secure)$/i.test(sKey)) { return false; }
var sExpires = "";
if (vEnd) {
switch (vEnd.constructor) {
case Number:
sExpires = vEnd === Infinity ? "; expires=Fri, 31 Dec 9999 23:59:59 GMT" : "; max-age=" + vEnd;
break;
case String:
sExpires = "; expires=" + vEnd;
break;
case Date:
sExpires = "; expires=" + vEnd.toUTCString();
break;
}
}
document.cookie = encodeURIComponent(sKey) + "=" + encodeURIComponent(sValue) + sExpires + (sDomain ? "; domain=" + sDomain : "") + (sPath ? "; path=" + sPath : "") + (bSecure ? "; secure" : "");
return true;
},
removeItem: function (sKey, sPath, sDomain) {
if (!sKey || !this.hasItem(sKey)) { return false; }
document.cookie = encodeURIComponent(sKey) + "=; expires=Thu, 01 Jan 1970 00:00:00 GMT" + ( sDomain ? "; domain=" + sDomain : "") + ( sPath ? "; path=" + sPath : "");
return true;
},
hasItem: function (sKey) {
return (new RegExp("(?:^|;\\s*)" + encodeURIComponent(sKey).replace(/[\-\.\+\*]/g, "\\$&") + "\\s*\\=")).test(document.cookie);
},
keys: /* optional method: you can safely remove it! */ function () {
var aKeys = document.cookie.replace(/((?:^|\s*;)[^\=]+)(?=;|$)|^\s*|\s*(?:\=[^;]*)?(?:\1|$)/g, "").split(/\s*(?:\=[^;]*)?;\s*/);
for (var nIdx = 0; nIdx < aKeys.length; nIdx++) { aKeys[nIdx] = decodeURIComponent(aKeys[nIdx]); }
return aKeys;
}
};
Mozilla has some tests to prove this works in all cases.
There is an alternative snippet here:
This is the benchmark I have run after finding some articles around the net.
With 2.4.0 the winner is re.match?(str)
(as suggested by @wiktor-stribizew), on previous versions, re =~ str
seems to be fastest, although str =~ re
is almost as fast.
#!/usr/bin/env ruby
require 'benchmark'
str = "aacaabc"
re = Regexp.new('a+b').freeze
N = 4_000_000
Benchmark.bm do |b|
b.report("str.match re\t") { N.times { str.match re } }
b.report("str =~ re\t") { N.times { str =~ re } }
b.report("str[re] \t") { N.times { str[re] } }
b.report("re =~ str\t") { N.times { re =~ str } }
b.report("re.match str\t") { N.times { re.match str } }
if re.respond_to?(:match?)
b.report("re.match? str\t") { N.times { re.match? str } }
end
end
Results MRI 1.9.3-o551:

stack size can indeed be unlimited. _STK_LIM
is the default, _STK_LIM_MAX
is something that differs per architecture, as can be seen from include/asm-generic/resource.h
:
/*
* RLIMIT_STACK default maximum - some architectures override it:
*/
#ifndef _STK_LIM_MAX
# define _STK_LIM_MAX RLIM_INFINITY
#endif
As can be seen from this example generic value is infinite, where RLIM_INFINITY
is, again, in generic case defined as:
/*
* SuS says limits have to be unsigned.
* Which makes a ton more sense anyway.
*
* Some architectures override this (for compatibility reasons):
*/
#ifndef RLIM_INFINITY
# define RLIM_INFINITY (~0UL)
#endif
So I guess the real answer is - stack size CAN be limited by some architecture, then unlimited stack trace will mean whatever _STK_LIM_MAX
is defined to, and in case it's infinity - it is infinite. For details on what it means to set it to infinite and what implications it might have, refer to the other answer, it's way better than mine.
If you write code with Happy path design pattern (i.e. for embedded device) you may simulate exception error processing (aka deffering or finally emulation) with operator "goto".
int process(int port)
{
int rc;
int fd1;
int fd2;
fd1 = open("/dev/...", ...);
if (fd1 == -1) {
rc = -1;
goto out;
}
fd2 = open("/dev/...", ...);
if (fd2 == -1) {
rc = -1;
goto out;
}
// Do some with fd1 and fd2 for example write(f2, read(fd1))
rc = 0;
out:
//if (rc != 0) {
(void)close(fd1);
(void)close(fd2);
//}
return rc;
}
It does not actually exception handler but it take you a way to handle error at fucntion exit.
P.S. You should be careful use goto only from same or more deep scopes and never jump variable declaration.
Try it, learn it:
DECLARE @r INT = 5
DECLARE @i INT = 0
DECLARE @F varchar(max) = ''
WHILE @i < @r
BEGIN
DECLARE @j INT = 0
DECLARE @o varchar(max) = ''
WHILE @j < @r - @i - 1
BEGIN
SET @o = @o + ' '
SET @j += 1
END
DECLARE @k INT = 0
WHILE @k < @i + 1
BEGIN
SET @o = @o + ' *' -- '*'
SET @k += 1
END
SET @i += 1
SET @F = @F + @o + CHAR(13)
END
PRINT @F
With date:
DECLARE @d DATE = '2019-11-01'
WHILE @d < GETDATE()
BEGIN
PRINT @d
SET @d = DATEADD(DAY,1,@d)
END
PRINT 'n'
PRINT @d

Guids are statistically unique. The odds of two different clients generating the same Guid are infinitesimally small (assuming no bugs in the Guid generating code). You may as well worry about your processor glitching due to a cosmic ray and deciding that 2+2=5 today.
Multiple threads allocating new guids will get unique values, but you should get that the function you are calling is thread safe. Which environment is this in?
Your syntax is for table valued function which return a resultset and can be queried like a table. For scalar function do
select dbo.fun_functional_score('01091400003') as [er]
You may try this one
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
textView.setTextAppearance(R.style.Lato_Bold);
} else {
textView.setTextAppearance(getActivity(), R.style.Lato_Bold);
}
Ólafur forgot the surrogate key:
A surrogate key in a database is a unique identifier for either an entity in the modeled world or an object in the database. The surrogate key is not derived from application data.
You can pass lists just like other types:
l = [1,2,3]
def stuff(a):
for x in a:
print a
stuff(l)
This prints the list l. Keep in mind lists are passed as references not as a deep copy.
First, Set :
ALTER TABLE person ALTER COLUMN phone DROP NOT NULL;
Version 1 is preferable because it is shorter and the compiler will in fact turn it into version 2 - no performance difference whatsoever.
More importantly given we have only 3 properties it might not make a difference, but at what point do you switch from concat to builder?
At the point where you're concatenating in a loop - that's usually when the compiler can't substitute StringBuilder
by itself.
I don't know if this is the best way, but it has worked for me.
$root = $_SERVER['DOCUMENT_ROOT'];
include($root."/path/to/file.php");
Try to add to your PATH variable the following:
C:\Users\YOUR_USER\AppData\Roaming\npm
I had the same problem and I solved adding the path to my node modules.
First execute the below command:
sp_who2
After that execute the below command with SPID, which you got from above command:
KILL {SPID value}
You can use zIndex
for placing a view on top of another. It works like the CSS z-index property - components with a larger zIndex
will render on top.

For those strictly looking for a solution that works for input or textarea, this is the simplest solution I've came across. Only a few lines of CSS and one line of JS.
The JavaScript sets a data-* attribute on the element equal to the value of the input. The input is set within a CSS grid, where that grid is a pseudo-element that uses that data-* attribute as its content. That content is what stretches the grid to the appropriate size based on the input value.

in the file group_vars/tests
:

This solution is for someone facing this issue while deploying a windows application,
I know this is late, but this maybe useful for someone in future, In my scenario, purely this is a connection string issue I developed a windows application using entity framework (DB First approach) and I published it, the code was worked fine on my machine, but it's not worked on the client machine
Reason for this issue:-
I updated the client machine connection string in App.config file, but this is wrong, if that is a windows application, then it will not read the connection string from App.config (For deployed machines), it will read from .exe.config file,
So after deployment, we need to change the connection string in "AppicationName".exe.config file
I also found myself in a similar position a couple of weeks ago. You can also do this by creating a custom ElementLocatorFactory (or simply passing in divA into the DefaultElementLocatorFactory) to see if it's a child of the first div - you would then call the appropriate PageFactory initElements method.
In this case if you did the following:
PageFactory.initElements(new DefaultElementLocatorFactory(divA), pageObjectInstance));
// The Page Object instance would then need a WebElement
// annotated with something like the xpath above or @FindBy(tagName = "input")
Here is my answer using the group by clause.
SELECT *
FROM feeds f
LEFT JOIN
(
SELECT artist_id, feed_id
FROM feeds_artists
GROUP BY artist_id, feed_id
) fa ON fa.feed_id = f.id
LEFT JOIN artists a ON a.artist_id = fa.artist_id
I know that this question is old but i would like to contribute too:
The main difference between others responses is the hashmap return.
@GetMapping("...")
@ResponseBody
public Map<String, Object> endPointExample(...) {
Map<String, Object> rtn = new LinkedHashMap<>();
rtn.put("pic", image);
rtn.put("potato", "King Potato");
return rtn;
}
This will return:
{"pic":"a17fefab83517fb...beb8ac5a2ae8f0449","potato":"King Potato"}
Based on the highly scientific method of watching animated gifs I would say Insertion and Bubble sorts are good candidates.
Another option of course is to use Javascript (Jquery here):
$('.box1,.box2').each(function(){
$(this).height($(this).parent().height());
})
i solved this in a shorter fashion.
Dim marray() as variant, array2() as variant, YY ,ZZ as integer
YY=1
ZZ=1
Redim marray(1 to 1000, 1 to 10)
Do while ZZ<100 ' this is populating the first array
marray(ZZ,YY)= "something"
ZZ=ZZ+1
YY=YY+1
Loop
'this part is where you store your array in another then resize and restore to original
array2= marray
Redim marray(1 to ZZ-1, 1 to YY)
marray = array2

Here's how I "automate" Dropping connected users in Oracle database:
# A shell script to Drop a Database Schema, forcing off any Connected Sessions (for example, before an Import)
# Warning! With great power comes great responsibility.
# It is often advisable to take an Export before Dropping a Schema
if [ "$1" = "" ]
then
echo "Which Schema?"
read schema
else
echo "Are you sure? (y/n)"
read reply
[ ! $reply = y ] && return 1
schema=$1
fi
sqlplus / as sysdba <<EOF
set echo on
alter user $schema account lock;
-- Exterminate all sessions!
begin
for x in ( select sid, serial# from v\$session where username=upper('$schema') )
loop
execute immediate ( 'alter system kill session '''|| x.Sid || ',' || x.Serial# || ''' immediate' );
end loop;
dbms_lock.sleep( seconds => 2 ); -- Prevent ORA-01940: cannot drop a user that is currently connected
end;
/
drop user $schema cascade;
quit
EOF
This happened to me as well. For me, Postfix was located at the same server as the PHP script, and the error was happening when I would be using SMTP authentication and smtp.domain.com instead of localhost.
So when I commented out these lines:
$mail->SMTPAuth = true;
$mail->SMTPSecure = "tls";
and set the host to
$mail->Host = "localhost";
instead
$mail->Host = 'smtp.mydomainiuse.com'
and it worked :)
Using parameter --force:
npm i -f
The term parameter refers to any declaration within the parentheses following the method/function name in a method/function declaration or definition; the term argument refers to any expression within the parentheses of a method/function call. i.e.
Please have a look at the below example for better understanding:
package com.stackoverflow.works;
public class ArithmeticOperations {
public static int add(int x, int y) { //x, y are parameters here
return x + y;
}
public static void main(String[] args) {
int x = 10;
int y = 20;
int sum = add(x, y); //x, y are arguments here
System.out.println("SUM IS: " +sum);
}
}
Thank you!
For anyone looking also for a solution for authentication, I would add on the scoped packages solution that you can have multiple lines in your .npmrc
file:
//internal-npm.example.com:8080/:_authToken=xxxxxxxxxxxxxxx
//registry.npmjs.org/:_authToken=yyyyyyyyyy
Each line represents a different NPM registry
For some algorithms you need a consistent bias when 'nearest' is a tie.
// round-to-nearest with mid-value bias towards positive infinity
int div_nearest( int n, int d )
{
if (d<0) n*=-1, d*=-1;
return (abs(n)+((d-(n<0?1:0))>>1))/d * ((n<0)?-1:+1);
}
This works regardless of the sign of the numerator or denominator.
If you want to match the results of round(N/(double)D)
(floating-point division and rounding), here are a few variations that all produce the same results:
int div_nearest( int n, int d )
{
int r=(n<0?-1:+1)*(abs(d)>>1); // eliminates a division
// int r=((n<0)^(d<0)?-1:+1)*(d/2); // basically the same as @ericbn
// int r=(n*d<0?-1:+1)*(d/2); // small variation from @ericbn
return (n+r)/d;
}
Note: The relative speed of (abs(d)>>1)
vs. (d/2)
is likely to be platform dependent.
There is no issue with your code.

Yes, #id
selectors combined with a multiple selector (comma) is perfectly valid in both jQuery and CSS.
However, for your example, since <script>
comes before the elements, you need a document.ready
handler, so it waits until the elements are in the DOM to go looking for them, like this:
<script>
$(function() {
$("#segement1,#segement2,#segement3").hide()
});
</script>
<div id="segement1"></div>
<div id="segement2"></div>
<div id="segement3"></div>
Updating with more options
list1 = ['foo', 'fob', 'faz', 'funk']
addstring = 'bar'
for index, value in enumerate(list1):
list1[index] = addstring + value #this will prepend the string
#list1[index] = value + addstring this will append the string
Avoid using keywords as variables like 'list', renamed 'list' as 'list1' instead
6 years later here, but for them who are stil facing this issue, I solved it as following.
It happened when my module had a different gradle version than the main project. I had gradle version 3.5.3
in project and an older version in module. So, I Just updated that version. The file is here:
./node-modules/[module-name]/android/build.gradle
By design it is to be done this way:
OutputStream out = ...;
try (Writer w = new OutputStreamWriter(out, "UTF-8")) {
w.write("Hello, World!");
} // or w.close(); //close will auto-flush
Probably my question should have been more specific. I actually know a base class for the string so solved it by:
ReportClass report = (ReportClass)Activator.CreateInstance(Type.GetType(reportClass));
The Activator.CreateInstance class has various methods to achieve the same thing in different ways. I could have cast it to an object but the above is of the most use to my situation.
You can make sure that the object in question is stringified before passing it to parse function by simply using JSON.stringify()

JSON.parse(JSON.stringify({"balance":0,"count":0,"time":1323973673061,"firstname":"howard","userId":5383,"localid":1,"freeExpiration":0,"status":false}));
or if you have JSON stored in some variable:
JSON.parse(JSON.stringify(yourJSONobject));
Another approach to add the class to element using pure JavaScript
For adding class:
document.getElementById("div1").classList.add("classToBeAdded");
For removing class:
document.getElementById("div1").classList.remove("classToBeRemoved");
Note: but not supported in IE <= 9 or Safari <=5.0
Suppose you want to write that in the same file, you can do as follows:
Set-Content -Path "C:\temp\Newtext.txt" -Value (get-content -Path "c:\Temp\Newtext.txt" | Select-String -Pattern 'H\|159' -NotMatch)
dictionary["C1"]=map(lambda x:x+10,dictionary["C1"])
Should do it...
After several days of searching found the EAN API - http://developer.ean.com/ - it is a very big one, but it provides really good information. Free demos, XML\JSON format. Looks good.
It's just bcz your JS gets loaded before the HTML part and so it can't find that element. Just put your whole JS code inside a function which will be called when the window gets loaded.
You can also put your Javascript code below the html.
Its very simple for those who are using API 21 or greater Use this code below
<resources>
<style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
<!-- Customize your theme here. -->
<item name="android:background">@color/colorDarkGrey</item>
</style>
<resources>
<style name="AppTheme" parent="Theme.AppCompat.Light.ActionBar">
<item name="android:background">@color/colorDarkGrey</item>
</style>
To find the last filled column use the following :
lastColumn = ActiveSheet.Cells(1, Columns.Count).End(xlToLeft).Column
; Default Value: On
; Development Value: Off
; Production Value: Off
; http://php.net/short-open-tag
;short_open_tag=Off <--Comment this out
; XAMPP for Linux is currently old fashioned
short_open_tag = On <--Uncomment this
Pass the method from Parent
component down as a prop
to your Child
component.
ie:
export default class Parent extends Component {
state = {
word: ''
}
handleCall = () => {
this.setState({ word: 'bar' })
}
render() {
const { word } = this.state
return <Child handler={this.handleCall} word={word} />
}
}
const Child = ({ handler, word }) => (
<span onClick={handler}>Foo{word}</span>
)
My solution expands on @tak3r's.
It returns an empty object when there are no query parameters and supports the array notation ?a=1&a=2&a=3
:
function getQueryParams () {
function identity (e) { return e; }
function toKeyValue (params, param) {
var keyValue = param.split('=');
var key = keyValue[0], value = keyValue[1];
params[key] = params[key]?[value].concat(params[key]):value;
return params;
}
return decodeURIComponent(window.location.search).
replace(/^\?/, '').split('&').
filter(identity).
reduce(toKeyValue, {});
}
Since you add ..
after cmake, it will jump up and up (just like cd ..
) in the directory. But if you want to run cmake under the same folder with CMakeLists.txt, please use .
instead of ..
.
It sounds like you may want to use something like SimpleDateFormat. http://java.sun.com/j2se/1.4.2/docs/api/java/text/SimpleDateFormat.html
You declare your date format and then call the parse method with your string.
private static final DateFormat DF = new SimpleDateFormat(...);
Date myDate = DF.parse("1234");
And as Guillaume says, set the timezone!
The accepted answer does not show 0 in integer place on giving input like 0.299. It shows .3 in WPF UI. So my suggestion to use following string format
<TextBox Text="{Binding Value, StringFormat={}{0:#,0.0}}"
Use a suitable guard in the outer loop. Set the guard in the inner loop before you break.
bool exitedInner = false;
for (int i = 0; i < N && !exitedInner; ++i) {
.... some outer loop stuff
for (int j = 0; j < M; ++j) {
if (sometest) {
exitedInner = true;
break;
}
}
if (!exitedInner) {
... more outer loop stuff
}
}
Or better yet, abstract the inner loop into a method and exit the outer loop when it returns false.
for (int i = 0; i < N; ++i) {
.... some outer loop stuff
if (!doInner(i, N, M)) {
break;
}
... more outer loop stuff
}
The word check_
in the name means that if the command (the shell in this case that returns the exit status of the last command (yum
in this case)) returns non-zero status then it raises CalledProcessError
exception. It is by design. If the command that you want to run may return non-zero status on success then either catch this exception or don't use check_
methods. You could use subprocess.call
in your case because you are ignoring the captured output, e.g.:
import subprocess
rc = subprocess.call(['grep', 'pattern', 'file'],
stdout=subprocess.DEVNULL, stderr=subprocess.STDOUT)
if rc == 0: # found
...
elif rc == 1: # not found
...
elif rc > 1: # error
...
You don't need shell=True
to run the commands from your question.
