I don't think so. The API's will provide access to delayed quotes, there is no way that real time data or tick data, will be provided for free.
To download ISIN code data the only place I see this is on the ISIN organizations website, www.isin.org. try http://isin.org, they should have a function where you can easily download.
I came across the same situation, I found the answer with use of socket library helpful but it doesn't provide support for ipv6 addresses. Found a better way for it:
Unfortunately it Works for python3 only
import ipaddress
def valid_ip(address):
try:
print ipaddress.ip_address(address)
return True
except:
return False
print valid_ip('10.10.20.30')
print valid_ip('2001:DB8::1')
print valid_ip('gibberish')
This worked for me: brew uninstall openssl; brew uninstall openssl; brew install https://github.com/tebelorg/Tump/releases/download/v1.0.0/openssl.rb

Since the accepted answer would represent overloading script method, I would like to suggest another which is, in my opinion, much cleaner and more secure due to XSS risks which come with overloading scripts.
I made a demo to show you how to use it in an action and how to inject one template into another, edit and then add to the document DOM.
<template id="mytemplate">
<style>
.image{
width: 100%;
height: auto;
}
</style>
<a href="#" class="list-group-item">
<div class="image">
<img src="" />
</div>
<p class="list-group-item-text"></p>
</a>
</template>
// select
var t = document.querySelector('#mytemplate');
// set
t.content.querySelector('img').src = 'demo.png';
t.content.querySelector('p').textContent= 'demo text';
// add to document DOM
var clone = document.importNode(t.content, true); // where true means deep copy
document.body.appendChild(clone);
+Its content is effectively inert until activated. Essentially, your markup is hidden DOM and does not render.
+Any content within a template won't have side effects. Scripts don't run, images don't load, audio doesn't play ...until the template is used.
+Content is considered not to be in the document. Using document.getElementById()
or querySelector()
in the main page won't return child nodes of a template.
+Templates can be placed anywhere inside of <head>
, <body>
, or <frameset>
and can contain any type of content which is allowed in those elements. Note that "anywhere" means that <template>
can safely be used in places that the HTML parser disallows.
Browser support should not be an issue but if you want to cover all possibilities you can make an easy check:
To feature detect
<template>
, create the DOM element and check that the .content property exists:
function supportsTemplate() {
return 'content' in document.createElement('template');
}
if (supportsTemplate()) {
// Good to go!
} else {
// Use old templating techniques or libraries.
}
<script>
tag has display:none
by default."text/javascript"
..innerHTML
. Run-time string parsing of user-supplied data can easily lead to XSS vulnerabilities.Full article: https://www.html5rocks.com/en/tutorials/webcomponents/template/#toc-old

I used the property
display: table;
and
display: table-cell;
to achieve the same.Link to fiddle below shows 3 tables wrapped in divs and these divs are further wrapped in a parent div
<div id='content'>
<div id='div-1'><!-- COntains table --></div>
<div id='div-2'><!-- contains two more divs that require to be arranged one below other --></div>
</div>
Here is the jsfiddle: http://jsfiddle.net/vikikamath/QU6WP/1/ I thought this might be helpful to someone looking to set divs in same line without using display-inline
Clean function can be called from VBA this way:
Range("A1").Value = Application.WorksheetFunction.Clean(Range("A1"))
However as written here, the CLEAN function was designed to remove the first 32 non-printing characters in the 7 bit ASCII code (values 0 through 31) from text. In the Unicode character set, there are additional nonprinting characters (values 127, 129, 141, 143, 144, and 157). By itself, the CLEAN function does not remove these additional nonprinting characters.
Rick Rothstein have written code to handle even this situation here this way:
Function CleanTrim(ByVal S As String, Optional ConvertNonBreakingSpace As Boolean = True) As String
Dim X As Long, CodesToClean As Variant
CodesToClean = Array(0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, _
21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 127, 129, 141, 143, 144, 157)
If ConvertNonBreakingSpace Then S = Replace(S, Chr(160), " ")
For X = LBound(CodesToClean) To UBound(CodesToClean)
If InStr(S, Chr(CodesToClean(X))) Then S = Replace(S, Chr(CodesToClean(X)), "")
Next
CleanTrim = WorksheetFunction.Trim(S)
End Function

It allows browsers to determine if they can handle the scripting/style language before making a request for the script or stylesheet (or, in the case of embedded script/style, identify which language is being used).
This would be much more important if there had been more competition among languages in browser space, but VBScript never made it beyond IE and PerlScript never made it beyond an IE specific plugin while JSSS was pretty rubbish to begin with.
The draft of HTML5 makes the attribute optional.
There's a plugin for jQuery to get GET params called .getUrlParams
For POST the only solution is echoing the POST into a javascript variable using PHP, like Moran suggested.
(Update) V5.1 & Hooks (Requires React >= 16.8)
You can use useHistory
, useLocation
and useRouteMatch
in your component to get match
, history
and location
.
const Child = () => {
const location = useLocation();
const history = useHistory();
const match = useRouteMatch("write-the-url-you-want-to-match-here");
return (
<div>{location.pathname}</div>
)
}
export default Child
(Update) V4 & V5
You can use withRouter
HOC in order to inject match
, history
and location
in your component props.
class Child extends React.Component {
static propTypes = {
match: PropTypes.object.isRequired,
location: PropTypes.object.isRequired,
history: PropTypes.object.isRequired
}
render() {
const { match, location, history } = this.props
return (
<div>{location.pathname}</div>
)
}
}
export default withRouter(Child)
(Update) V3
You can use withRouter
HOC in order to inject router
, params
, location
, routes
in your component props.
class Child extends React.Component {
render() {
const { router, params, location, routes } = this.props
return (
<div>{location.pathname}</div>
)
}
}
export default withRouter(Child)
Original answer
If you don't want to use the props, you can use the context as described in React Router documentation
First, you have to set up your childContextTypes
and getChildContext
class App extends React.Component{
getChildContext() {
return {
location: this.props.location
}
}
render() {
return <Child/>;
}
}
App.childContextTypes = {
location: React.PropTypes.object
}
Then, you will be able to access to the location object in your child components using the context like this
class Child extends React.Component{
render() {
return (
<div>{this.context.location.pathname}</div>
)
}
}
Child.contextTypes = {
location: React.PropTypes.object
}
I decided to write a class from this thread that may be helpful to others. Note that this is currently intended to write in the "files" directory only (e.g. does not write to "sdcard" paths).

!== should match the value and data type
!= just match the value ignoring the data type
$num = '1';
$num2 = 1;
$num == $num2; // returns true
$num === $num2; // returns false because $num is a string and $num2 is an integer
Had the same problem. Since you can still get data using the .data() method, you only have to figure out a way to write to the elements. This is the helper method I use. Like most people have said, you will have to use .attr. I have it replacing any _ with - as I know it does that. I'm not aware of any other characters it replaces...however I have not researched that.
function ExtendElementData(element, object){
//element is what you want to set data on
//object is a hash/js-object
var keys = Object.keys(object);
for (var i = 0; i < keys.length; i++){
var key = keys[i];
$(element).attr('data-'+key.replace("_", "-"), object[key]);
}
}
EDIT: 5/1/2017
I found there were still instances where you could not get the correct data using built in methods so what I use now is as follows:
function setDomData(element, object){
//object is a hash
var keys = Object.keys(object);
for (var i = 0; i < keys.length; i++){
var key = keys[i];
$(element).attr('data-'+key.replace("_", "-"), object[key]);
}
};
function getDomData(element, key){
var domObject = $(element).get(0);
var attKeys = Object.keys(domObject.attributes);
var values = null;
if (key != null){
values = $(element).attr('data-' + key);
} else {
values = {};
var keys = [];
for (var i = 0; i < attKeys.length; i++) {
keys.push(domObject.attributes[attKeys[i]]);
}
for (var i = 0; i < keys.length; i++){
if(!keys[i].match(/data-.*/)){
values[keys[i]] = $(element).attr(keys[i]);
}
}
}
return values;
};
I use this command for simple rotate a file:
mv output.log `date +%F`-output.log
In local folder I have 2019-09-25-output.log
You can make a relative shortcut manually by changing the file path. First in the usual context-menu you create a new shortcut of Windows for your file and in the properties -> location of your file:
%windir%\explorer.exe "..\data\run.bat"
I'm seeing the same thing. A quick google found this question and a bug on the chromium forums. It seems that the --user-data-dir
flag is now required.
Edit to add user-data-dir guide
Regular implementation (no yield - will do everything in memory):
def getPermutations(array):
if len(array) == 1:
return [array]
permutations = []
for i in range(len(array)):
# get all perm's of subarray w/o current item
perms = getPermutations(array[:i] + array[i+1:])
for p in perms:
permutations.append([array[i], *p])
return permutations
Yield implementation:
def getPermutations(array):
if len(array) == 1:
yield array
else:
for i in range(len(array)):
perms = getPermutations(array[:i] + array[i+1:])
for p in perms:
yield [array[i], *p]
The basic idea is to go over all the elements in the array for the 1st position, and then in 2nd position go over all the rest of the elements without the chosen element for the 1st, etc. You can do this with recursion, where the stop criteria is getting to an array of 1 element - in which case you return that array.
I disagree with the answer from Thomasleveil.
Making mysql bind to 172.17.42.1 will prevent other programs using the database on the host to reach it. This will only work if all your database users are dockerized.
Making mysql bind to 0.0.0.0 will open the db to outside world, which is not only a very bad thing to do, but also contrary to what the original question author wants to do. He explicitly says "The MySql is running on localhost and not exposing a port to the outside world, so its bound on localhost"
To answer the comment from ivant
"Why not bind mysql to docker0 as well?"
This is not possible. The mysql/mariadb documentation explicitly says it is not possible to bind to several interfaces. You can only bind to 0, 1, or all interfaces.
As a conclusion, I have NOT found any way to reach the (localhost only) database on the host from a docker container. That definitely seems like a very very common pattern, but I don't know how to do it.
Just put
export HOME=/blah/whatever
at the point in the script where you want the change to happen. Since each process has its own set of environment variables, this definition will automatically cease to have any significance when the script terminates (and with it the instance of bash that has a changed environment).
First of all what value do you have in this pice of code? int temp;
? You can't tell because in every single compilation it will have different value - you should initialize your value to not have trash value from memory. Next question is: why you assign this temp value to your array?
If you want to stick with your solution I would change reverse function like this:
void reverse(int arr[], int count)
{
int temp = 0;
for (int i = 0; i < count/2; ++i)
{
temp = arr[count - i - 1];
arr[count - i - 1] = arr[i];
arr[i] = temp;
}
for (int i = 0; i < count; ++i)
{
std::cout << arr[i] << " ";
}
}
Now it will works but you have other options to handle this problem.
Solution using pointers:
void reverse(int arr[], int count)
{
int* head = arr;
int* tail = arr + count - 1;
for (int i = 0; i < count/2; ++i)
{
if (head < tail)
{
int tmp = *tail;
*tail = *head;
*head = tmp;
head++; tail--;
}
}
for (int i = 0; i < count; ++i)
{
std::cout << arr[i] << " ";
}
}
And ofc like Carlos Abraham says use build in function in algorithm
library
Basing on your solutions I've made some trick:
When you use it, your HTML will be only
<div data-keep-ratio="75%">
<div>Main content</div>
</div>
To use it this way make: CSS:
*[data-keep-ratio] {
display: block;
width: 100%;
position: relative;
}
*[data-keep-ratio] > * {
position: absolute;
left: 0;
right: 0;
top: 0;
bottom: 0;
}
and js (jQuery)
$('*[data-keep-ratio]').each(function(){
var ratio = $(this).data('keep-ratio');
$(this).css('padding-bottom', ratio);
});
And having this you just set attr data-keep-ratio
to height/width and that's it.
Add the goal like -
<build>
<defaultGoal>install</defaultGoal>
<!-- Source directory configuration -->
<sourceDirectory>src</sourceDirectory>
</build>
This will solve the issue
I'm a relative novice compared to all the experts on Stack Overflow.
I have 2 versions of jupyter notebook running (one through a fresh Anaconda Navigator installation and one through ????). I think this is because Anaconda was installed as a local installation on my Mac (per Anaconda instructions).
I already had python 3.7 installed. After that, I used my terminal to open jupyter notebook and I think that it put another version globally onto my Mac.
However, I'm not sure because I'm just learning through trial and error!
I did the terminal command:
conda install -c anaconda certifi
(as directed above, but it didn't work.)
My python 3.7 is installed on OS Catalina10.15.3 in:
The certificate is at:
I tried to find the Install Certificate.command ... but couldn't find it through looking through the file structures...not in Applications...not in links above.
I finally installed it by finding it through Spotlight (as someone suggested above). And it double clicked automatically and installed ANOTHER certificate in the same folder as:
NONE of the above solved anything for me...I still got the same error.
So, I solved the problem by:
I can't tell you why this worked. But it solved the problem for me.
I just want to save someone the hassle next time. If someone can tell my why it worked, that would be terrific.
I didn't try the other terminal commands because of the 2 versions of jupyter notebook that I knew were a problem. I just don't know how to fix that.
I wrapped the correct answer of this question in a function that can add multiple leading zero's but defaults to adding 1 zero.
function zeroFill(nr, depth){
depth = (depth === undefined)? 1 : depth;
var zero = "0";
for (var i = 0; i < depth; ++i) {
zero += "0";
}
return (zero + nr).slice(-(depth + 1));
}
for working with numbers only and not more than 2 digits, this is also an approach:
function zeroFill(i) {
return (i < 10 ? '0' : '') + i
}
read.table
wants to return a data.frame
, which must have an element in each column. Therefore R expects each row to have the same number of elements and it doesn't fill in empty spaces by default. Try read.table("/PathTo/file.csv" , fill = TRUE )
to fill in the blanks.
e.g.
read.table( text= "Element1 Element2
Element5 Element6 Element7" , fill = TRUE , header = FALSE )
# V1 V2 V3
#1 Element1 Element2
#2 Element5 Element6 Element7
A note on whether or not to set header = FALSE
... read.table
tries to automatically determine if you have a header row thus:
header
is set toTRUE
if and only if the first row contains one fewer field than the number of columns
Asset.objects.filter( project__name__contains="Foo" )
You are trying to load a XIB named DetailViewController
, but no such XIB exists or it's not member of your current target.
${project.basedir}
is the root directory of your project.
${project.build.directory}
is equivalent to ${project.basedir}/target
as it is defined here: https://github.com/apache/maven/blob/trunk/maven-model-builder/src/main/resources/org/apache/maven/model/pom-4.0.0.xml#L53
EDIT: After your comments, I understand that you want to pass variable through your form.
You can do this using hidden field:
<input type='hidden' name='var' value='<?php echo "$var";?>'/>
In PHP action File:
<?php
if(isset($_POST['var'])) $var=$_POST['var'];
?>
Or using sessions: In your first page:
$_SESSION['var']=$var;
start_session();
should be placed at the beginning of your php page.
In PHP action File:
if(isset($_SESSION['var'])) $var=$_SESSION['var'];
First Answer:
You can also use $GLOBALS
:
if (isset($_POST['save_exit']))
{
echo $GLOBALS['var'];
}
Check this documentation for more informations.

You can't: It's a security feature in all modern browsers.
For IE8, it's off by default, but can be reactivated using a security setting:
When a file is selected by using the input type=file object, the value of the value property depends on the value of the "Include local directory path when uploading files to a server" security setting for the security zone used to display the Web page containing the input object.
The fully qualified filename of the selected file is returned only when this setting is enabled. When the setting is disabled, Internet Explorer 8 replaces the local drive and directory path with the string C:\fakepath\ in order to prevent inappropriate information disclosure.
In all other current mainstream browsers I know of, it is also turned off. The file name is the best you can get.
More detailed info and good links in this question. It refers to getting the value server-side, but the issue is the same in JavaScript before the form's submission.
Edit: As of February, 2020, there's now a first-class UI for automatically mounting Drive.
First, open the file browser on the left hand side. It will show a 'Mount Drive' button. Once clicked, you'll see a permissions prompt to mount Drive, and afterwards your Drive files will be present with no setup when you return to the notebook. The completed flow looks like so:
The original answer follows, below. (This will also still work for shared notebooks.)
You can mount your Google Drive files by running the following code snippet:
from google.colab import drive
drive.mount('/content/drive')
Then, you can interact with your Drive files in the file browser side panel or using command-line utilities.
You must make your foreign key nullable:
public class User
{
public int Id { get; set; }
public int? CountryId { get; set; }
public virtual Country Country { get; set; }
}
It might be a good practice to define variables like below:
v_departmentid departments.department_id%TYPE;
NOT like below:
v_departmentid NUMBER(4)
i use this in linux :

then restore your_file.sql
mysql -u yourdBUser -p yourdBPasswd yourdB < your_file.sql
See the relevant documentation in general and specifically
from matplotlib.ticker import FormatStrFormatter
fig, ax = plt.subplots()
ax.yaxis.set_major_formatter(FormatStrFormatter('%.2f'))
Best way would be to declare Boolean
variable within the code block and return
it at end of code, like this:
public boolean Test(){
boolean booleanFlag= true;
if (A>B)
{booleanFlag= true;}
else
{booleanFlag = false;}
return booleanFlag;
}
I find this the best way.
you can also use vbscript
Set objFS = CreateObject("Scripting.FileSystemObject")
strFolder = "c:\test"
strDestination = "c:\tmp\"
Set objFolder = objFS.GetFolder(strFolder)
Go(objFolder)
Sub Go(objDIR)
If objDIR <> "\System Volume Information" Then
For Each eFolder in objDIR.SubFolders
Go eFolder
Next
For Each strFile In objDIR.Files
strFileName = strFile.Name
strExtension = objFS.GetExtensionName(strFile)
If strExtension = "doc" Then
objFS.CopyFile strFile , strDestination & strFileName
End If
Next
End If
End Sub
save as mycopy.vbs and on command line
c:\test> cscript /nologo mycopy.vbs
I overrode the Count method of the associated FragmentStatePagerAdapter and have it return the total count minus the number of pages to hide:
public class MyAdapter : Android.Support.V13.App.FragmentStatePagerAdapter
{
private List<Fragment> _fragments;
public int TrimmedPages { get; set; }
public MyAdapter(Android.App.FragmentManager fm) : base(fm) { }
public MyAdapter(Android.App.FragmentManager fm, List<Android.App.Fragment> fragments) : base(fm)
{
_fragments = fragments;
TrimmedPages = 0;
}
public override int Count
{
//get { return _fragments.Count; }
get { return _fragments.Count - TrimmedPages; }
}
}
So, if there are 3 fragments initially added to the ViewPager, and only the first 2 should be shown until some condition is met, override the page count by setting TrimmedPages to 1 and it should only show the first two pages.
This works good for pages on the end, but wont really help for ones on the beginning or middle (though there are plenty of ways of doing this).
AdBlockers usually have some rules, i.e. they match the URIs against some type of expression (sometimes they also match the DOM against expressions, not that this matters in this case).
Having rules and expressions that just operate on a tiny bit of text (the URI) is prone to create some false-positives...
Besides instructing your users to disable their extensions (at least on your site) you can also get the extension and test which of the rules/expressions blocked your stuff, provided the extension provides enough details about that. Once you identified the culprit, you can either try to avoid triggering the rule by using different URIs, report the rule as incorrect or overly-broad to the team that created it, or both. Check the docs for a particular add-on on how to do that.
For example, AdBlock Plus has a Blockable items view that shows all blocked items on a page and the rules that triggered the block. And those items also including XHR requests.

At this point, I would definitely consider using em
values instead of pixels. For more information, check this post: https://zellwk.com/blog/media-query-units/.
For your last question, why ? I'll try to explain with what I know
A brief explanation of those three status codes in layman's terms.
If caching is enabled in the server
For some files browser is deciding to request from server and for some it's deciding to read from stored (cached) files. Why is this ? Every files has an expiry date, so
If a file is not expired then the browser will use from cache (200 cache).
If file is expired, browser requests server for a file. Server check file in both places (browser and server). If same file found, server refuses the request. As per protocol browser uses existing file.
look at this nginx configuration
location / {
add_header Cache-Control must-revalidate;
expires 60;
etag on;
...
}
Here the expiry is set to 60 seconds, so all static files are cached for 60 seconds. So if u request a file again within 60 seconds browser will read from memory (200 memory). If u request after 60 seconds browser will request server (304).
I assumed that the file is not changed after 60 seconds, in that case you would get 200 (ie, updated file will be fetched from server).
So, if the servers are configured with different expiring and caching headers (policies), the status may differ.
In your case you are using cdn, the main purpose of cdn is high availability and fast delivery. Therefore they use multiple servers. Even though it seems like files are in same directory, cdn might use multiple servers to provide u content, if those servers have different configurations. Then these status can change. Hope it helps.

Also you can use guppy module.

To compare Strings for equality, don't use ==. The == operator checks to see if two objects are exactly the same object:
In Java there are many string comparisons.
String s = "something", t = "maybe something else";
if (s == t) // Legal, but usually WRONG.
if (s.equals(t)) // RIGHT
if (s > t) // ILLEGAL
if (s.compareTo(t) > 0) // also CORRECT>
Take a look at this solution using Linq. His example is similar in that he needed different markup for every 3rd item.
foreach( var myItem in Model.Members.Select(x,i) => new {Member = x, Index = i){
...
}
Are you using an error handler? If you're ignoring errors and try to name a sheet the same as an existing sheet or a name with invalid characters, it could be just skipping over that line. See the CleanSheetName function here
http://www.dailydoseofexcel.com/archives/2005/01/04/naming-a-sheet-based-on-a-cell/
for a list of invalid characters that you may want to check for.
Update
Other things to try: Fully qualified references, throwing in a Doevents, code cleaning. This code qualifies your Sheets reference to ThisWorkbook (you can change it to ActiveWorkbook if that suits). It also adds a thousand DoEvents (stupid overkill, but if something's taking a while to get done, this will allow it to - you may only need one DoEvents if this actually fixes anything).
Dim WS As Worksheet
Dim i As Long
With ThisWorkbook
Set WS = .Worksheets.Add(After:=.Sheets(.Sheets.Count))
End With
For i = 1 To 1000
DoEvents
Next i
WS.Name = txtSheetName.Value
Finally, whenever I have a goofy VBA problem that just doesn't make sense, I use Rob Bovey's CodeCleaner. It's an add-in that exports all of your modules to text files then re-imports them. You can do it manually too. This process cleans out any corrupted p-code that's hanging around.
You can use the following
p{word-break: break-all;}
<p>LoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolorLoremipsumdolor</p>
On linux command line, you can simply execute:
curl -H "Content-Type: text/xml; charset=utf-8" -H "SOAPAction:" -d @your_soap_request.xml -X POST https://ws.paymentech.net/PaymentechGateway
If you really want to "ExecuteCall a shell script in current shell with sudo permission" you can use exec
to...
replace the shell with a given program (executing it, not as new process)
I insist on replacing "execute" with "call" because the former has a meaning that includes creating a new process and ID, where the latter is ambiguous and leaves room for creativity, of which I am full.
Consider this test case and look closely at pid 1337
# Don't worry, the content of this script is cat'ed below
$ ./test.sh -o foo -p bar
User ubuntu is running...
PID TT USER COMMAND
775 pts/1 ubuntu -bash
1408 pts/1 ubuntu \_ bash ./test.sh -o foo -p bar
1411 pts/1 ubuntu \_ ps -t /dev/pts/1 -fo pid,tty,user,args
User root is running...
PID TT USER COMMAND
775 pts/1 ubuntu -bash
1337 pts/1 root \_ sudo ./test.sh -o foo -p bar
1412 pts/1 root \_ bash ./test.sh -o foo -p bar
1415 pts/1 root \_ ps -t /dev/pts/1 -fo pid,tty,user,args
Take 'exec' out of the command and this script would get cat-ed twice. (Try it.)
#!/usr/bin/env bash
echo; echo "User $(whoami) is running..."
ps -t $(tty) -fo pid,tty,user,args
if [[ $EUID > 0 ]]; then
# exec replaces the current process effectively ending execution so no exit is needed.
exec sudo "$0" "$@"
fi
echo; echo "Take 'exec' out of the command and this script would get cat-ed twice. (Try it.)"; echo
cat $0
Here is another test using sudo -s
$ ps -fo pid,tty,user,args; ./test2.sh
PID TT USER COMMAND
10775 pts/1 ubuntu -bash
11496 pts/1 ubuntu \_ ps -fo pid,tty,user,args
User ubuntu is running...
PID TT USER COMMAND
10775 pts/1 ubuntu -bash
11497 pts/1 ubuntu \_ bash ./test2.sh
11500 pts/1 ubuntu \_ ps -fo pid,tty,user,args
User root is running...
PID TT USER COMMAND
11497 pts/1 root sudo -s
11501 pts/1 root \_ /bin/bash
11503 pts/1 root \_ ps -fo pid,tty,user,args
$ cat test2.src
echo; echo "User $(whoami) is running..."
ps -fo pid,tty,user,args
$ cat test2.sh
#!/usr/bin/env bash
source test2.src
exec sudo -s < test2.src
And a simpler test using sudo -s
$ ./exec.sh
bash's PID:25194 user ID:7809
systemd(1)---bash(23064)---bash(25194)---pstree(25196)
Finally...
bash's PID:25199 user ID:0
systemd(1)---bash(23064)---sudo(25194)---bash(25199)---pstree(25201)
$ cat exec.sh
#!/usr/bin/env bash
pid=$$
id=$(id -u)
echo "bash's PID:$pid user ID:$id"
pstree -ps $pid
# the quoted EOF is important to prevent shell expansion of the $...
exec sudo -s <<EOF
echo
echo "Finally..."
echo "bash's PID:\$\$ user ID:\$(id -u)"
pstree -ps $pid
EOF
Before you lose more time solving the problem, like me, try just to restart your windows machine. Worked for me after applying all the other solutions.
For Spring Boot 2.1.0 and later you can use
mvn spring-boot:run -Dspring-boot.run.profiles=foo,bar
For "partial" I always use it as follows:
If there's something you need to include in a page that you need to go via the controller (like you would with an Ajax call) then use "Html.RenderPartial".
If you have a 'static' include that isn't linked to a controller per-se and just in the 'shared' folder for example, use "HTML.partial"
If you want to use a format that allows you to keep the number like your entry this format works for me:
"# \\%"
A race condition is a situation on concurrent programming where two concurrent threads or processes compete for a resource and the resulting final state depends on who gets the resource first.
If you want your container ports to bind on your ipv4 address, just :
works for me on docker 1.9.1
There is no best way, it depends on your use case.
Person
(you should start the name with a capital letter) is called the constructor function. This is similar to classes in other OO languages.Update: As requested examples for the third way.
Dependent properties:
The following does not work as this
does not refer to book
. There is no way to initialize a property with values of other properties in a object literal:
var book = {
price: somePrice * discount,
pages: 500,
pricePerPage: this.price / this.pages
};
instead, you could do:
var book = {
price: somePrice * discount,
pages: 500
};
book.pricePerPage = book.price / book.pages;
// or book['pricePerPage'] = book.price / book.pages;
Dynamic property names:
If the property name is stored in some variable or created through some expression, then you have to use bracket notation:
var name = 'propertyName';
// the property will be `name`, not `propertyName`
var obj = {
name: 42
};
// same here
obj.name = 42;
// this works, it will set `propertyName`
obj[name] = 42;
so, it seems there arent, but you can use this workaround using guava or an equivalent Function class implementation, because that class is extremely simple, ex.:
assert false : new com.google.common.base.Function<Void,String>(){
@Override public String apply(Void input) {
//your complex code go here
return "weird message";
}}.apply(null);
yes, this is dead code just to exemplify how to create a complex code block (within {}) to do something so specific that shouldnt bother us on creating any method for it, AKA inline!
I think the most efficient way to do this is this is using RemoveAt
:
rows.RemoveAt(rows.Count - 1)
This can be massively simplified with just 1 line of code in viewDidAppear:
override func viewDidAppear(animated: Bool) {
super.viewDidAppear(animated)
tableViewHeightConstraint.constant = tableView.contentSize.height
}
The Bearer
authentication scheme is what you are looking for.
Is it related to bears?
Errr... No :)
According to the Oxford Dictionaries, here's the definition of bearer:
bearer /'b??r?/
noun
A person or thing that carries or holds something.
A person who presents a cheque or other order to pay money.
The first definition includes the following synonyms: messenger, agent, conveyor, emissary, carrier, provider.
And here's the definition of bearer token according to the RFC 6750:
Bearer Token
A security token with the property that any party in possession of the token (a "bearer") can use the token in any way that any other party in possession of it can. Using a bearer token does not require a bearer to prove possession of cryptographic key material (proof-of-possession).
The Bearer
authentication scheme is registered in IANA and originally defined in the RFC 6750 for the OAuth 2.0 authorization framework, but nothing stops you from using the Bearer
scheme for access tokens in applications that don't use OAuth 2.0.
Stick to the standards as much as you can and don't create your own authentication schemes.
An access token must be sent in the Authorization
request header using the Bearer
authentication scheme:
2.1. Authorization Request Header Field
When sending the access token in the
Authorization
request header field defined by HTTP/1.1, the client uses theBearer
authentication scheme to transmit the access token.For example:
GET /resource HTTP/1.1 Host: server.example.com Authorization: Bearer mF_9.B5f-4.1JqM
[...]
Clients SHOULD make authenticated requests with a bearer token using the
Authorization
request header field with theBearer
HTTP authorization scheme. [...]
In case of invalid or missing token, the Bearer
scheme should be included in the WWW-Authenticate
response header:
3. The WWW-Authenticate Response Header Field
If the protected resource request does not include authentication credentials or does not contain an access token that enables access to the protected resource, the resource server MUST include the HTTP
WWW-Authenticate
response header field [...].All challenges defined by this specification MUST use the auth-scheme value
Bearer
. This scheme MUST be followed by one or more auth-param values. [...].For example, in response to a protected resource request without authentication:
HTTP/1.1 401 Unauthorized WWW-Authenticate: Bearer realm="example"
And in response to a protected resource request with an authentication attempt using an expired access token:
HTTP/1.1 401 Unauthorized WWW-Authenticate: Bearer realm="example", error="invalid_token", error_description="The access token expired"
I had the same problem. I used a trigger and in that trigger I called a procedure which computed some values into 2 OUT variables. When I tried to print the result in the trigger body, nothing showed on screen. But then I solved this problem by making 2 local variables in a function, computed what I need with them and finally, copied those variables in your OUT procedure variables. I hope it'll be useful and successful!
This belongs in a comment to Phil Hunt's answer but alas I don't have the rep.
To strip the ".00" off the end of your number string, parsename is super-handy. It tokenizes period-delimited strings and returns the specified element, starting with the rightmost token as element 1.
SELECT PARSENAME(CONVERT(varchar, CAST(987654321 AS money), 1), 2)
Yields "987,654,321"
For people still looking a couple of years later, things have changed a bit. You can now use the queue
for .fadeIn()
as well so that it will work like this:
$('.tooltip').fadeIn({queue: false, duration: 'slow'});
$('.tooltip').animate({ top: "-10px" }, 'slow');
This has the benefit of working on display: none
elements so you don't need the extra two lines of code.
<link rel="stylesheet" href="{{ URL::asset('css/styles.css') }}">
It will search for the file in your project public
folder
The problem may be that ssh is trying to connect to all the different IPs that www.google.com
resolves to. For example on my machine:

If I run it with a specific IP, it returns much faster.
EDIT: I've timed it (with time
) and the results are:
It is rare, in reality, that you would want to use an array. Definitely use a List<T>
any time you want to add/remove data, since resizing arrays is expensive. If you know the data is fixed length, and you want to micro-optimise for some very specific reason (after benchmarking), then an array may be useful.
List<T>
offers a lot more functionality than an array (although LINQ evens it up a bit), and is almost always the right choice. Except for params
arguments, of course. ;-p
As a counter - List<T>
is one-dimensional; where-as you have have rectangular (etc) arrays like int[,]
or string[,,]
- but there are other ways of modelling such data (if you need) in an object model.
See also:
That said, I make a lot of use of arrays in my protobuf-net project; entirely for performance:
byte[]
is pretty much essential for encoding;byte[]
buffer which I fill before sending down to the underlying stream (and v.v.); quicker than BufferedStream
etc;Foo[]
rather than List<Foo>
), since the size is fixed once built, and needs to be very fast.But this is definitely an exception; for general line-of-business processing, a List<T>
wins every time.
If you are using the Eloquent ORM you should consider using scopes. This would keep your logic in the model where it belongs.
So, in the model you would have:
public function scopeIdDescending($query)
{
return $query->orderBy('id','DESC');
}
And outside the model you would have:
$posts = Post::idDescending()->get();

TL;DR
Error #1064 means that MySQL can't understand your command. To fix it:
Read the error message. It tells you exactly where in your command MySQL got confused.
Examine your command. If you use a programming language to create your command, use
echo
,console.log()
, or its equivalent to show the entire command so you can see it.Check the manual. By comparing against what MySQL expected at that point, the problem is often obvious.
Check for reserved words. If the error occurred on an object identifier, check that it isn't a reserved word (and, if it is, ensure that it's properly quoted).
Error messages may look like gobbledygook, but they're (often) incredibly informative and provide sufficient detail to pinpoint what went wrong. By understanding exactly what MySQL is telling you, you can arm yourself to fix any problem of this sort in the future.
As in many programs, MySQL errors are coded according to the type of problem that occurred. Error #1064 is a syntax error.
Whilst "syntax" is a word that many programmers only encounter in the context of computers, it is in fact borrowed from wider linguistics. It refers to sentence structure: i.e. the rules of grammar; or, in other words, the rules that define what constitutes a valid sentence within the language.
For example, the following English sentence contains a syntax error (because the indefinite article "a" must always precede a noun):
This sentence contains syntax error a.
Whenever one issues a command to a computer, one of the very first things that it must do is "parse" that command in order to make sense of it. A "syntax error" means that the parser is unable to understand what is being asked because it does not constitute a valid command within the language: in other words, the command violates the grammar of the programming language.
It's important to note that the computer must understand the command before it can do anything with it. Because there is a syntax error, MySQL has no idea what one is after and therefore gives up before it even looks at the database and therefore the schema or table contents are not relevant.
Obviously, one needs to determine how it is that the command violates MySQL's grammar. This may sound pretty impenetrable, but MySQL is trying really hard to help us here. All we need to do is…
MySQL not only tells us exactly where the parser encountered the syntax error, but also makes a suggestion for fixing it. For example, consider the following SQL command:
UPDATE my_table WHERE id=101 SET name='foo'
That command yields the following error message:
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'WHERE id=101 SET name='foo'' at line 1
MySQL is telling us that everything seemed fine up to the word WHERE
, but then a problem was encountered. In other words, it wasn't expecting to encounter WHERE
at that point.
Messages that say ...near '' at line...
simply mean that the end of command was encountered unexpectedly: that is, something else should appear before the command ends.
Programmers often create SQL commands using a programming language. For example a php program might have a (wrong) line like this:
$result = $mysqli->query("UPDATE " . $tablename ."SET name='foo' WHERE id=101");
If you write this this in two lines
$query = "UPDATE " . $tablename ."SET name='foo' WHERE id=101"
$result = $mysqli->query($query);
then you can add echo $query;
or var_dump($query)
to see that the query actually says
UPDATE userSET name='foo' WHERE id=101
Often you'll see your error immediately and be able to fix it.
MySQL is also recommending that we "check the manual that corresponds to our MySQL version for the right syntax to use". Let's do that.
I'm using MySQL v5.6, so I'll turn to that version's manual entry for an UPDATE
command. The very first thing on the page is the command's grammar (this is true for every command):
UPDATE [LOW_PRIORITY] [IGNORE] table_reference
SET col_name1={expr1|DEFAULT} [, col_name2={expr2|DEFAULT}] ...
[WHERE where_condition]
[ORDER BY ...]
[LIMIT row_count]
The manual explains how to interpret this syntax under Typographical and Syntax Conventions, but for our purposes it's enough to recognise that: clauses contained within square brackets [
and ]
are optional; vertical bars |
indicate alternatives; and ellipses ...
denote either an omission for brevity, or that the preceding clause may be repeated.
We already know that the parser believed everything in our command was okay prior to the WHERE
keyword, or in other words up to and including the table reference. Looking at the grammar, we see that table_reference
must be followed by the SET
keyword: whereas in our command it was actually followed by the WHERE
keyword. This explains why the parser reports that a problem was encountered at that point.
Of course, this was a simple example. However, by following the two steps outlined above (i.e. observing exactly where in the command the parser found the grammar to be violated and comparing against the manual's description of what was expected at that point), virtually every syntax error can be readily identified.
I say "virtually all", because there's a small class of problems that aren't quite so easy to spot—and that is where the parser believes that the language element encountered means one thing whereas you intend it to mean another. Take the following example:
UPDATE my_table SET where='foo'
Again, the parser does not expect to encounter WHERE
at this point and so will raise a similar syntax error—but you hadn't intended for that where
to be an SQL keyword: you had intended for it to identify a column for updating! However, as documented under Schema Object Names:
If an identifier contains special characters or is a reserved word, you must quote it whenever you refer to it. (Exception: A reserved word that follows a period in a qualified name must be an identifier, so it need not be quoted.) Reserved words are listed at Section 9.3, “Keywords and Reserved Words”.
[ deletia ]The identifier quote character is the backtick (“
`
”):mysql> SELECT * FROM `select` WHERE `select`.id > 100;
If the
ANSI_QUOTES
SQL mode is enabled, it is also permissible to quote identifiers within double quotation marks:mysql> CREATE TABLE "test" (col INT); ERROR 1064: You have an error in your SQL syntax... mysql> SET sql_mode='ANSI_QUOTES'; mysql> CREATE TABLE "test" (col INT); Query OK, 0 rows affected (0.00 sec)
Here's a two line code I found online that might be helpful for a beginner
# Absolute value of the 32/64
abs_image_in32_64 = np.absolute(image_in32_64)
image_8U = np.uint8(abs_image_in32_64)
Yeah, as others have suggested, this error seems to mean that ssh-agent is installed but its service (on windows) hasn't been started.
You can check this by running in Windows PowerShell:
> Get-Service ssh-agent
And then check the output of status is not running.
Status Name DisplayName
------ ---- -----------
Stopped ssh-agent OpenSSH Authentication Agent
Then check that the service has been disabled by running
> Get-Service ssh-agent | Select StartType
StartType
---------
Disabled
I suggest setting the service to start manually. This means that as soon as you run ssh-agent, it'll start the service. You can do this through the Services GUI or you can run the command in admin mode:
> Get-Service -Name ssh-agent | Set-Service -StartupType Manual
Alternatively, you can set it through the GUI if you prefer.

Use console.log(JSON.stringify(result))
to get the JSON in a string format.
EDIT: If your intention is to get the id and other properties from the result object and you want to see it console to know if its there then you can check with hasOwnProperty
and access the property if it does exist:
var obj = {id : "007", name : "James Bond"};
console.log(obj); // Object { id: "007", name: "James Bond" }
console.log(JSON.stringify(obj)); //{"id":"007","name":"James Bond"}
if (obj.hasOwnProperty("id")){
console.log(obj.id); //007
}
ioutil.ReadDir
is a good find, but if you click and look at the source you see that it calls the method Readdir of os.File. If you are okay with the directory order and don't need the list sorted, then this Readdir method is all you need.
None of the above answers worked perfectly for me. So I found another way which works well.
Just add a scroll.(namespace)
listener and set scrollTop
of the document
to the latest of it's value...
and also remove the listener in your close script.
// in case of bootstrap modal example:
$('#myModal').on('shown.bs.modal', function () {
var documentScrollTop = $(document).scrollTop();
$(document).on('scroll.noScroll', function() {
$(document).scrollTop(documentScrollTop);
return false;
});
}).on('hidden.bs.modal', function() {
$(document).off('scroll.noScroll');
});
seems, this does not work well on chrome. any suggestion to fix it ?
You can find ===
and !==
operators in several other dynamically-typed languages as well. It always means that the two values are not only compared by their "implied" value (i.e. either or both values might get converted to make them comparable), but also by their original type.
That basically means that if 0 == "0"
returns true, 0 === "0"
will return false because you are comparing a number and a string. Similarly, while 0 != "0"
returns false, 0 !== "0"
returns true.
<img style="float: right;" alt="" src="http://example.com/image.png" />

Concise without regular expressions, but HTTPResponseCode=> httpresponse_code:

name = name.replace("_", "")
_cas = lambda _x : [_i.isupper() for _i in _x]
seq = zip(_cas(name[1:-1]), _cas(name[2:]))
ss = [_x + 1 for _x, (_i, _j) in enumerate(seq) if (_i, _j) == (False, True)]
return "".join([ch + "_" if _x in ss else ch for _x, ch in numerate(name.lower())])
The easiest way might be to get it from NuGet:

The OP needed to cast as string outside the {% set ... %}
.
But if that not your case you can do:
{% set curYear = 2013 | string() %}
Note that you need the parenthesis on that jinja filter.
If you're concatenating 2 variables, you can also use the ~
custom operator.
That Exception is thrown if there is already a key in the dictionary when you try to add the new one.
There must be more than one line in rct3Lines
with the same first word. You can't have 2 entries in the same dictionary with the same key.
You need to decide what you want to happen if the key already exists - if you want to just update the value where the key exists you can simply
rct3Features[items[0]]=items[1]
but, if not you may want to test if the key already exists with:
if(rect3Features.ContainsKey(items[0]))
{
//Do something
}
else
{
//Do something else
}
I would propose simply:
def get_digest(file_path):
h = hashlib.sha256()
with open(file_path, 'rb') as file:
while True:
# Reading is buffered, so we can read smaller chunks.
chunk = file.read(h.block_size)
if not chunk:
break
h.update(chunk)
return h.hexdigest()
All other answers here seem to complicate too much. Python is already buffering when reading (in ideal manner, or you configure that buffering if you have more information about underlying storage) and so it is better to read in chunks the hash function finds ideal which makes it faster or at lest less CPU intensive to compute the hash function. So instead of disabling buffering and trying to emulate it yourself, you use Python buffering and control what you should be controlling: what the consumer of your data finds ideal, hash block size.
I found this solution that is simple and worked for me:
<form ...>
<input ...>
<button ... onclick="this.disabled=true;this.value='Submitting...'; this.form.submit();">
</form>

Referencing my comments on other answers. This is how I would work out the difference in days based on 24 hours and calender days. the days attribute works well for 24 hours and the function works best for calendar checks.
from datetime import timedelta, datetime
def cal_days_diff(a,b):
A = a.replace(hour = 0, minute = 0, second = 0, microsecond = 0)
B = b.replace(hour = 0, minute = 0, second = 0, microsecond = 0)
return (A - B).days
if __name__ == '__main__':
x = datetime(2013, 06, 18, 16, 00)
y = datetime(2013, 06, 19, 2, 00)
print (y - x).days # 0
print cal_days_diff(y, x) # 1
z = datetime(2013, 06, 20, 2, 00)
print (z - x).days # 1
print cal_days_diff(z, x) # 2
UPDATE totals
SET total = total + 1
WHERE name = 'bill';
If you want to make sure the current value is indeed 203 (and not accidently increase it again) you can also add another condition:
UPDATE totals
SET total = total + 1
WHERE name = 'bill'
AND total = 203;
*NgIf can create problem here , so either use display none css or easier way is to Use [hidden]="!condition"
Check your firewall. When you disable it, then you can connect. If you want/can't disable the firewall, add a rule for your remote connection.
not sure if that's what you need but try this in ruby console:
h = Hash.new
h["name"] = "test"
h["post_number"] = 20
h["active"] = true
h
obviously it will return you a hash in console. if you want to return a hash from within a method - instead of just "h" try using "return h.inspect", something similar to:
def wordcount(str)
h = Hash.new()
str.split.each do |key|
if h[key] == nil
h[key] = 1
else
h[key] = h[key] + 1
end
end
return h.inspect
end
Same with something more complex...getting the ec2 instance region from within the instance.

With Git 2.7 (release January 5th, 2015), you have a more coherent solution using git remote
:
git remote get-url origin
(nice pendant of git remote set-url origin <newurl>
)
See commit 96f78d3 (16 Sep 2015) by Ben Boeckel (mathstuf
).
(Merged by Junio C Hamano -- gitster
-- in commit e437cbd, 05 Oct 2015):
remote: add get-url subcommand
Expanding
insteadOf
is a part ofls-remote --url
and there is no way to expandpushInsteadOf
as well.
Add aget-url
subcommand to be able to query both as well as a way to get all configured URLs.
get-url:
Retrieves the URLs for a remote.
Configurations forinsteadOf
andpushInsteadOf
are expanded here.
By default, only the first URL is listed.
- With '
--push
', push URLs are queried rather than fetch URLs.- With '
--all
', all URLs for the remote will be listed.
Before git 2.7, you had:
git config --get remote.[REMOTE].url
git ls-remote --get-url [REMOTE]
git remote show [REMOTE]
Currently, setTextSize(float size)

android.widget.TextView.java source code
/**
* Set the default text size to the given value, interpreted as "scaled

* user font size preference.
*
* <p>Note: if this TextView has the auto-size feature enabled than this function is no-op.
*
* @param size The scaled pixel size.
*
* @attr ref android.R.styleable#TextView_textSize
*/
@android.view.RemotableViewMethod
public void setTextSize(float size) {
setTextSize(TypedValue.COMPLEX_UNIT_SP, size);
}
Example using
textView.setTextSize(20); // set your text size = 20sp
Warning: Both solutions given ( astype() and apply() ) do not preserve NULL values in either the nan or the None form.

I believe this is fixed by the implementation of to_string()

You only need to copy <iframe> from the YouTube Embed section (click on SHARE below the video and then EMBED and copy the entire iframe).
The correct way of setting a listener to a fragment is by setting it when it is attached. The problem I had was that onAttachFragment() was never called. After some investigation I realised that I had been using getFragmentManager instead of getChildFragmentManager
Here is how I do it:
MyDialogFragment dialogFragment = MyDialogFragment.newInstance("title", "body");
dialogFragment.show(getChildFragmentManager(), "SOME_DIALOG");
Attach it in onAttachFragment:
@Override
public void onAttachFragment(Fragment childFragment) {
super.onAttachFragment(childFragment);
if (childFragment instanceof MyDialogFragment) {
MyDialogFragment dialog = (MyDialogFragment) childFragment;
dialog.setListener(new MyDialogFragment.Listener() {
@Override
public void buttonClicked() {
}
});
}
}
The three operators have related but different meanings, despite the misleading note from the IDE.
The ::
operator is known as the scope resolution operator, and it is used to get from a namespace or class to one of its members.
The .
and ->
operators are for accessing an object instance's members, and only comes into play after creating an object instance. You use .
if you have an actual object (or a reference to the object, declared with &
in the declared type), and you use ->
if you have a pointer to an object (declared with *
in the declared type).
The this
object is always a pointer to the current instance, hence why the ->
operator is the only one that works.
Examples:
// In a header file
namespace Namespace {
class Class {
private:
int x;
public:
Class() : x(4) {}
void incrementX();
};
}
// In an implementation file
namespace Namespace {
void Class::incrementX() { // Using scope resolution to get to the class member when we aren't using an instance
++(this->x); // this is a pointer, so using ->. Equivalent to ++((*this).x)
}
}
// In a separate file lies your main method
int main() {
Namespace::Class myInstance; // instantiates an instance. Note the scope resolution
Namespace::Class *myPointer = new Namespace::Class;
myInstance.incrementX(); // Calling a function on an object instance.
myPointer->incrementX(); // Calling a function on an object pointer.
(*myPointer).incrementX(); // Calling a function on an object pointer by dereferencing first
return 0;
}
I think ResponseEntityExceptionHandler
meets your requirements. A sample piece of code for HTTP 400:
@ControllerAdvice
public class MyExceptionHandler extends ResponseEntityExceptionHandler {
@ResponseStatus(value = HttpStatus.BAD_REQUEST)
@ExceptionHandler({HttpMessageNotReadableException.class, MethodArgumentNotValidException.class,
HttpRequestMethodNotSupportedException.class})
public ResponseEntity<Object> badRequest(HttpServletRequest req, Exception exception) {
// ...
}
}

You need an external library for this.
JSONArray jsonA = JSONArray.fromObject(mybeanList);
System.out.println(jsonA);
Google GSON is one of such libraries
You can also take a look here for examples on converting Java object collection to JSON string.
The best and easiest way to do it (currently in 2015 2020) is using flexbox:
.parent-selector {
display: flex;
align-items: center;

vertical-align: middle;
}
Working example:
div {_x000D_
border: 1px solid red;_x000D_
height: 150px;_x000D_
width: 350px;_x000D_
text-align: center;_x000D_
_x000D_
/* Actual code */_x000D_
display: table-cell;_x000D_
vertical-align: middle;_x000D_
}
_x000D_
<div>_x000D_
<p>Hola</p>_x000D_
</div>
_x000D_
If it does not work you can try setting its parent as display: table;
:
.parent-selector {
display: table;
}
Edit: You have this method plus all the methods covered on this question in this other question: How do I vertically center text with CSS?
According to this Video if you use the ProGuard you don't need even think about Enums performance issues!!
Proguard can in many situations optimize Enums to INT values on your behalf so really don't need to think about it or do any work.
Without checking your code, I think what you are describing is that your pages are out of sync and you have stale data.
You say you are changing the number of pages, then crashing because you are accessing the old set of pages. This sounds to me like you are not calling pageAdapter.notifyDataSetChanged()
after changing your data.
When your viewPager
is showing page 3 of a set of 10 pages, and you change to a set with only 5, then call notifyDataSetChanged()
, what you'll find is you are now viewing page 3 of the new set. If you were previously viewing page 8 of the old set, after putting in the new set and calling notifyDataSetChanged()
you will find you are now viewing the last page of the new set without crashing.
If you simply change your current page, you may just be masking the problem.
According to the jQuery documentation for .keypress(), it does not catch non-printable characters, so backspace will not work on keypress, but it is caught in keydown and keyup:
The keypress event is sent to an element when the browser registers keyboard input. This is similar to the keydown event, except that modifier and non-printing keys such as Shift, Esc, and delete trigger keydown events but not keypress events. Other differences between the two events may arise depending on platform and browser. (https://api.jquery.com/keypress/)
In some instances keyup isn't desired or has other undesirable effects and keydown is sufficient, so one way to handle this is to use keydown
to catch all keystrokes then set a timeout of a short interval so that the key is entered, then do processing in there after.
jQuery(el).keydown( function() {
var that = this; setTimeout( function(){
/** Code that processes backspace, etc. **/
}, 100 );
} );
A complete solution is here
it's explained very nice with sample code. However, be careful that it does not close the application.Add the line Application.Current.Shutdown(); to gracefully close the app.
If you're registering a domain and the termination (ex .com
) it is not IDN, as Aaron Hathaway said:
Hostnames are composed of series of labels concatenated with dots, as are all domain names. For example, en.wikipedia.org
is a hostname. Each label must be between 1 and 63 characters long, and the entire hostname (including the delimiting dots but not a trailing dot) has a maximum of 253 ASCII characters.
The Internet standards (Requests for Comments) for protocols mandate that component hostname labels may contain only the ASCII letters a
through z
(in a case-insensitive manner), the digits 0
through 9
, and the hyphen -
. The original specification of hostnames in RFC 952, mandated that labels could not start with a digit or with a hyphen, and must not end with a hyphen. However, a subsequent specification (RFC 1123) permitted hostname labels to start with digits. No other symbols, punctuation characters, or white space are permitted.
Later, Spain with it's .es
, .com.es
, .org.es
, .nom,es
, .gob.es
and .edu.es
introduced IDN tlds, if your tld is one of .es
or any other that supports it, any character can be used, but you can't combine alphabets like Latin, Greek or Cyril in one hostname, and that it respects the things that can't go at the start or at the end.
If you're using non-registered tlds, just for local networking, like with local DNS or with hosts files, you can treat them all as IDN.
Keep in mind some programs could not work well, especially old, outdated and unpopular ones.
The following seems to work:
import datetime
print (datetime.datetime.now().strftime("%y"))
The datetime.data object that it wants is on the "left" of the dot rather than the right. You need an instance of the datetime to call the method on, which you get through now()
I know that this thread is quite old, however, I am missing here one option. If you have metadata (in any format) that you want to send along with the data to upload, you can make a single multipart/related
request.
The Multipart/Related media type is intended for compound objects consisting of several inter-related body parts.
You can check RFC 2387 specification for more in-depth details.
Basically each part of such a request can have content with different type and all parts are somehow related (e.g. an image and it metadata). The parts are identified by a boundary string, and the final boundary string is followed by two hyphens.
Example:
POST /upload HTTP/1.1
Host: www.hostname.com
Content-Type: multipart/related; boundary=xyz
Content-Length: [actual-content-length]
--xyz
Content-Type: application/json; charset=UTF-8
{
"name": "Sample image",
"desc": "...",
...
}
--xyz
Content-Type: image/jpeg
[image data]
[image data]
[image data]
...
--foo_bar_baz--
One more option, not exactly what you asked, but can be useful:
Go to Settings
-> Editor
-> File and code templates
-> Includes
tab (on the right). There is a template header for the new files, you can use the username here:
/**
* @author myname
*/
For system username use:
/**
* @author ${USER}
*/
Here is some PowerShell that creates a single TypeScript definition file a library that includes multiple *.js
files with modern JavaScript.
First, change all the extensions to .ts
.
Get-ChildItem | foreach { Rename-Item $_ $_.Name.Replace(".js", ".ts") }
Second, use the TypeScript compiler to generate definition files. There will be a bunch of compiler errors, but we can ignore those.
Get-ChildItem | foreach { tsc $_.Name }
Finally, combine all the *.d.ts
files into one index.d.ts
, removing the import
statements and removing the default
from each export statement.
Remove-Item index.d.ts;
Get-ChildItem -Path *.d.ts -Exclude "Index.d.ts" | `
foreach { Get-Content $_ } | `
where { !$_.ToString().StartsWith("import") } | `
foreach { $_.Replace("export default", "export") } | `
foreach { Add-Content index.d.ts $_ }
This ends with a single, usable index.d.ts
file that includes many of the definitions.
I was able to figure out the solution:
start notepad "myfile.txt"
"myshortcut.lnk"
exit
I'd like to add one important aspect to other answers, which actually explained this topic to me in the best way:
If 2 joined tables contain M and N rows, then cross join will always produce (M x N) rows, but full outer join will produce from MAX(M,N) to (M + N) rows (depending on how many rows actually match "on" predicate).
EDIT:
From logical query processing perspective, CROSS JOIN does indeed always produce M x N rows. What happens with FULL OUTER JOIN is that both left and right tables are "preserved", as if both LEFT and RIGHT join happened. So rows, not satisfying ON predicate, from both left and right tables are added to the result set.
If anybody needs a simple thing, following is a simple key-expiring set. It might be converted to a map easily.
public class CacheSet<K> {
public static final int TIME_OUT = 86400 * 1000;
LinkedHashMap<K, Hit> linkedHashMap = new LinkedHashMap<K, Hit>() {
@Override
protected boolean removeEldestEntry(Map.Entry<K, Hit> eldest) {
final long time = System.currentTimeMillis();
if( time - eldest.getValue().time > TIME_OUT) {
Iterator<Hit> i = values().iterator();
i.next();
do {
i.remove();
} while( i.hasNext() && time - i.next().time > TIME_OUT );
}
return false;
}
};
public boolean putIfNotExists(K key) {
Hit value = linkedHashMap.get(key);
if( value != null ) {
return false;
}
linkedHashMap.put(key, new Hit());
return true;
}
private static class Hit {
final long time;
Hit() {
this.time = System.currentTimeMillis();
}
}
}
Slightly related, I was looking for the unique combinations and I came up with this method:
def unique_columns(df,columns):
result = pd.Series(index = df.index)
groups = meta_data_csv.groupby(by = columns)
for name,group in groups:
is_unique = len(group) == 1
result.loc[group.index] = is_unique
assert not result.isnull().any()
return result
And if you only want to assert that all combinations are unique:
df1.set_index(['A','B']).index.is_unique
I would recommend a regular expression for this since it handles cases that you might not have considered.
var input = "o1 1232.5467 1232.5467 1232.5467 1232.5467 1232.5467 1232.5467";
var regex = new Regex(@"^(.*? .*?) ");
var match = regex.Match(input);
if (match.Success)
{
Console.WriteLine(string.Format("'{0}'", match.Groups[1].Value));
}
You could create a class Dictionary so you can interact with the Dictionary list easily:
class Dictionary {_x000D_
constructor() {_x000D_
this.items = {};_x000D_
}_x000D_
has(key) {_x000D_
return key in this.items;_x000D_
}_x000D_
set(key,value) {_x000D_
this.items[key] = value;_x000D_
}_x000D_
delete(key) {_x000D_
if( this.has(key) ){_x000D_
delete this.items[key]_x000D_
return true;_x000D_
}_x000D_
return false;_x000D_
}_x000D_
}_x000D_
_x000D_
var d = new Dictionary();_x000D_
d.set(1, "value1")_x000D_
d.set(2, "value2")_x000D_
d.set(3, "value3")_x000D_
console.log(d.has(2));_x000D_
d.delete(2);_x000D_
console.log(d.has(2));
_x000D_
If ever you need to do the same thing with mongoid:
Model.all.rename(:old_field, :new_field)
UPDATE
There is change in the syntax in monogoid 4.0.0
:
Model.all.rename(old_field: :new_field)
here is a solution:
Bitmap bitmap = BitmapFactory.decodeFile(filePath);
You can use this code:
$dateValue = strtotime('2012-06-05');
$year = date('Y',$dateValue);
$monthName = date('F',$dateValue);
$monthNo = date('m',$dateValue);
printf("m=[%s], m=[%d], y=[%s]\n", $monthName, $monthNo, $year);
For horizontal only, you can trick the box-shadow using overflow on its parent div:
<div class="parent">
<div class="box-shadow">content</div>
</div>
.parent{
overflow:hidden;
}
.box-shadow{
box-shadow: box-shadow: 0 5px 5px 0 #000;
}

You can use Array.push()
for appending elements to an array.
For deleting, it is best to use this.$delete(array, index)
for reactive objects.
Vue.delete( target, key )
: Delete a property on an object. If the object is reactive, ensure the deletion triggers view updates. This is primarily used to get around the limitation that Vue cannot detect property deletions, but you should rarely need to use it.
- name: Move the src file to dest
command: mv /path/to/src /path/to/dest
args:
removes: /path/to/src
creates: /path/to/dest
This runs the mv
command only when /path/to/src
exists and /path/to/dest
does not, so it runs once per host, moves the file, then doesn't run again.
I use this method when I need to move a file or directory on several hundred hosts, many of which may be powered off at any given time. It's idempotent and safe to leave in a playbook.
If you don't want to modify the dataframe, you could use a custom formatter for that column.
import pandas as pd
pd.options.display.float_format = '${:,.2f}'.format
df = pd.DataFrame([123.4567, 234.5678, 345.6789, 456.7890],
index=['foo','bar','baz','quux'],
columns=['cost'])
print df.to_string(formatters={'cost':'${:,.2f}'.format})
yields
cost
foo $123.46
bar $234.57
baz $345.68
quux $456.79
<div>
is a block-level element and <span>
is an inline element.
If you wanted to do something with some inline text, <span>
is the way to go since it will not introduce line breaks that a <div>
would.
As noted by others, there are some semantics implied with each of these, most significantly the fact that a <div>
implies a logical division in the document, akin to maybe a section of a document or something, a la:
<div id="Chapter1">
<p>Lorem ipsum dolor sit amet, <span id="SomeSpecialText1">consectetuer adipiscing</span> elit. Duis congue vehicula purus.</p>
<p>Nam <span id="SomeSpecialText2">eget magna nec</span> sapien fringilla euismod. Donec hendrerit.</p>
</div>
I see only two options:
The trick is to visit the original page using the 64-bit version of Internet Explorer. The site will then offer you the appropriate download options.
Although this topic is a decade old, I still often require to 'backpatch' existing applications which relied upon the mysql
extension — the original programmers were too lazy to refactor all their code, and just tell customers to make sure that they run the latest PHP 5.6 version available.
PHP 5.6 is now officially deprecated; in other words, developers had a decade to get rid of their dependencies upon mysql
and move to PDO
(or, well, mysqli
...). But... changing so much legacy code is expensive, and not every manager is willing to pay for the uncountable hours to 'fix' projects with dozens of thousands of lines.
I've searched for many solutions, and, in my case, I often used the solution presented by @esty-shlomovitz — but in the meantime, I've found something even better:
https://www.phpclasses.org/package/9199-PHP-Replace-mysql-functions-using-the-mysqli-extension.html
(you need to register to download it, but that just takes a minute)
These are just two files which act as drop-in replacements for the whole mysql
extension and very cleverly emulate pretty much everything (using mysqli
) without the need to worry much about it. Of course, it's not a perfect solution, but very likely it will work in 99% of all cases out there.
Also, a good tutorial for dealing with the chores of migration (listing many of the common pitfalls when migrating) can also be found here: https://www.phpclasses.org/blog/package/9199/post/3-Smoothly-Migrate-your-PHP-Code-using-the-Old-MySQL-extension-to-MySQLi.html

Update: @crashwap noted on the comments below that you can also get the same code directly from GitHub. Thanks for the tip, @crashwap :-)
Since Python 3.5 (PEP 448 -- Additional Unpacking Generalizations) one can use the following literal syntax to convert a tuple to a list:
>>> t = (1,2,3)
>>> lst = [*t]
>>> lst
[1, 2, 3]
>>> *lst, # back to tuple
(1, 2, 3)
A list comprehension can be use to convert a tuple of tuples to a list of lists:
>>> level1 = (
... (1,1,1,1,1,1),
... (1,0,0,0,0,1),
... (1,0,0,0,0,1),
... (1,0,0,0,0,1),
... (1,0,0,0,0,1),
... (1,1,1,1,1,1))
>>> level1_list = [[*row] for row in level1]
>>> level1_list
[[1, 1, 1, 1, 1, 1],
[1, 0, 0, 0, 0, 1],
[1, 0, 0, 0, 0, 1],
[1, 0, 0, 0, 0, 1],
[1, 0, 0, 0, 0, 1],
[1, 1, 1, 1, 1, 1]]
>>> *((*row,) for row in level1_list),
((1, 1, 1, 1, 1, 1),
(1, 0, 0, 0, 0, 1),
(1, 0, 0, 0, 0, 1),
(1, 0, 0, 0, 0, 1),
(1, 0, 0, 0, 0, 1),
(1, 1, 1, 1, 1, 1))
>>> _ == level1

Just Add "JsonRequestBehavior.AllowGet" on your Json object.
Add to app.module.ts
import {MatIconModule} from '@angular/material/icon';
& link in your global index.html.
It couldn't get simpler than this in Swift 2 and the latest Xcode 7 (no need to specify enum type, or .rawValue, descriptors etc...)
Updated for Swift 3 and Xcode 8:
enum Audience {
case Public
case Friends
case Private
}
let audience: Audience = .Public // or, let audience = Audience.Public
print(audience) // "Public"
You could create an extension method to add all property values through reflection:
public static DataSet ToDataSet<T>(this IList<T> list)
{
Type elementType = typeof(T);
DataSet ds = new DataSet();
DataTable t = new DataTable();
ds.Tables.Add(t);
//add a column to table for each public property on T
foreach(var propInfo in elementType.GetProperties())
{
t.Columns.Add(propInfo.Name, propInfo.PropertyType);
}
//go through each property on T and add each value to the table
foreach(T item in list)
{
DataRow row = t.NewRow();
foreach(var propInfo in elementType.GetProperties())
{
row[propInfo.Name] = propInfo.GetValue(item, null);
}
}
return ds;
}
AStyle can be customized in great detail for C++ and Java (and others too)
This is a source code formatting tool.
clang-format is a powerful command line tool bundled with the clang compiler which handles even the most obscure language constructs in a coherent way.
It can be integrated with Visual Studio, Emacs, Vim (and others) and can format just the selected lines (or with git/svn to format some diff).
It can be configured with a variety of options listed here.
When using config files (named .clang-format
) styles can be per directory - the closest such file in parent directories shall be used for a particular file.
Styles can be inherited from a preset (say LLVM or Google) and can later override different options
It is used by Google and others and is production ready.
Also look at the project UniversalIndentGUI. You can experiment with several indenters using it: AStyle, Uncrustify, GreatCode, ... and select the best for you. Any of them can be run later from a command line.
Uncrustify has a lot of configurable options. You'll probably need Universal Indent GUI (in Konstantin's reply) as well to configure it.

There is a nice css tricks article about this here: https://css-tricks.com/gradient-borders-in-css/
I was able to come up with a pretty simple, single element, solution to this using multiple backgrounds and the background-origin property.

background: linear-gradient(#222, #222),
linear-gradient(to right, red, purple);
background-origin: padding-box, border-box;
background-repeat: no-repeat; /* this is important */

Personally, I like setting the options directly with an assignment statement as it is easy to find via tab completion thanks to iPython. I find it hard to remember what the exact option names are, so this method works for me.
For instance, all I have to remember is that it begins with pd.options
pd.options.<TAB>
Most of the options are available under display
pd.options.display.<TAB>
From here, I usually output what the current value is like this:
pd.options.display.max_rows
60
I then set it to what I want it to be:
pd.options.display.max_rows = 100
Also, you should be aware of the context manager for options, which temporarily sets the options inside of a block of code. Pass in the option name as a string followed by the value you want it to be. You may pass in any number of options in the same line:
with pd.option_context('display.max_rows', 100, 'display.max_columns', 10):
some pandas stuff
You can also reset an option back to its default value like this:
pd.reset_option('display.max_rows')
And reset all of them back:
pd.reset_option('all')
It is still perfectly good to set options via pd.set_option
. I just find using the attributes directly is easier and there is less need for get_option
and set_option
.
I noticed that this question was not marked as answered after 2 years - I think the closest answer is Richards, but it can be simplified quite a lot to this:
list1.Concat(list2)
.ToLookup(p => p.Name)
.Select(g => g.Aggregate((p1, p2) => new Person
{
Name = p1.Name,
Value = p1.Value,
Change = p2.Value - p1.Value
}));
Although this won't error in the case where you have duplicate names in either set.
Some other answers have suggested using unioning - this is definitely not the way to go as it will only get you a distinct list, without doing the combining.
I'm a big fan of Business Rules Engines, since it can help you make your life much easier as a programmer. One of the first experiences I've had while working on a Data Warehouse project was to find Stored Procedures containing complicated CASE structures stretching over entire pages. It was a nightmare to debug, since it was very difficult to understand the logic applied in such long CASE structures, and to determine if you have an overlapping between a rule at page 1 of the code and another from page 5. Overall, we had more than 300 such rules embedded in the code.
When we've received a new development requirement, for something called Accounting Destination, which was involving treating more than 3000 rules, i knew something had to change. Back then I've been working on a prototype which later on become the parent of what now is a Custom Business Rule engine, capable of handling all SQL standard operators. Initially we've been using Excel as an authoring tool and , later on, we've created an ASP.net application which will allow the Business Users to define their own business rules, without the need of writing code. Now the system works fine, with very few bugs, and contains over 7000 rules for calculating this Accounting Destination. I don't think such scenario would have been possible by just hard-coding. And the users are pretty happy that they can define their own rules without IT becoming their bottleneck.
Still, there are limits to such approach:
More details on this topic can be found on a post I've written: http://dwhbp.com/post/2011/10/30/Implementing-a-Business-Rule-Engine.aspx
Overall, the biggest advantage of using a Business Rule Engines is that it allows the users to take back control over the Business Rule definitions and authoring, without the need of going to the IT department each time they need to modify something. It also the reduces the workload over IT development teams, which can now focus on building stuff with more added value.

One thing you need to realize is in Ruby everything is an object. Given that, if you don't define your methods within Module
or Class
, Ruby will put it within the Object
class. So, your code will be local to the Object
scope.
A typical approach on Object Oriented Programming is encapsulate all logic within a class:
class Point
attr_accessor :x, :y
# If we don't specify coordinates, we start at 0.
def initialize(x = 0, y = 0)
# Notice that `@` indicates instance variables.
@x = x
@y = y
end
# Here we override the `+' operator.
def +(point)
Point.new(self.x + point.x, self.y + point.y)
end
# Here we draw the point.
def draw(offset = nil)
if offset.nil?
new_point = self
else
new_point = self + offset
end
new_point.draw_absolute
end
def draw_absolute
puts "x: #{self.x}, y: #{self.y}"
end
end
first_point = Point.new(100, 200)
second_point = Point.new(3, 4)
second_point.draw(first_point)
Hope this clarifies a bit.
I'm guessing that you're referring to the fact that you often have to put a 'return false;' statement in your event handlers, i.e.
<a href="#" onclick="doSomeFunction(); return false;">...
The 'return false;' in this case stops the browser from jumping to the current location, as indicated by the href="#" - instead, only doSomeFunction() is executed. It's useful for when you want to add events to anchor tags, but don't want the browser jumping up and down to each anchor on each click

If you need the VM to be aware when the CheckBox
is changed, you should really bind the CheckBox
to the VM, and not a static value:
public class ViewModel
{
private bool _caseSensitive;
public bool CaseSensitive
{
get { return _caseSensitive; }
set
{
_caseSensitive = value;
NotifyPropertyChange(() => CaseSensitive);
Settings.Default.bSearchCaseSensitive = value;
}
}
}
XAML:
<CheckBox Content="Case Sensitive" IsChecked="{Binding CaseSensitive}"/>
Try this:
var alphaExp = /^[a-zA-Z]+$/;
if(document.myForm.name.match(alphaExp))
{
//Your logice will be here.
}
else{
alert("Please enter only alphabets");
}
Thanks.
The date function can return this if you specify the format correctly:
$daynum = date("w", strtotime("wednesday"));
will return 0 for Sunday through to 6 for Saturday.
An alternative format is:
$daynum = date("N", strtotime("wednesday"));
which will return 1 for Monday through to 7 for Sunday (this is the ISO-8601 represensation).
Bash alias absolutely does accept parameters. I just added an alias to create a new react app which accepts the app name as a parameter. Here's my process:
Open the bash_profile for editing in nano
nano /.bash_profile
Add your aliases, one per line:
alias gita='git add .'
alias gitc='git commit -m "$@"'
alias gitpom='git push origin master'
alias creact='npx create-react-app "$@"'
note: the "$@" accepts parameters passed in like "creact my-new-app"
Save and exit nano editor
ctrl+o to to write (hit enter); ctrl+x to exit
Tell terminal to use the new aliases in .bash_profile
source /.bash_profile
That's it! You can now use your new aliases
Here's how I have setup my cron tasks. I have one to make daily backups of SQL database (using rake) and another to expire cache once a month. Any output is logged in a file log/cron_log. My crontab looks like this:
crontab -l # command to print all cron tasks
crontab -e # command to edit/add cron tasks
# Contents of crontab
0 1 * * * cd /home/lenart/izziv. whiskas.si/current; /bin/sh cron_tasks >> log/cron_log 2>&1
0 0 1 * * cd /home/lenart/izziv.whiskas.si/current; /usr/bin/env /usr/local/bin/ruby script/runner -e production lib/monthly_cron.rb >> log/cron_log 2>&1
The first cron task makes daily db backups. The contents of cron_tasks are the following:
/usr/local/bin/rake db:backup RAILS_ENV=production; date; echo "END OF OUTPUT ----";
The second task was setup later and uses script/runner to expire cache once a month (lib/monthly_cron.rb):
#!/usr/local/bin/ruby
# Expire challenge cache
Challenge.force_expire_cache
puts "Expired cache for Challenges (Challenge.force_expire_cache) #{Time.now}"
I guess I could backup database some other way but so far it works for me :)
The paths to rake and ruby can vary on different servers. You can see where they are by using:
whereis ruby # -> ruby: /usr/local/bin/ruby
whereis rake # -> rake: /usr/local/bin/rake
You could also try listing the css in the style sheet as !important
I beleive I'm little late here. But I think this would help the new peeps!

Bootstrap 3
Yes, it's possible. This "off-canvas" example should help to get you started.
https://codeply.com/p/esYgHWB2zJ
Basically you need to wrap the layout in an outer div, and use media queries to toggle the layout on smaller screens.
/* collapsed sidebar styles */
@media screen and (max-width: 767px) {
.row-offcanvas {
position: relative;
-webkit-transition: all 0.25s ease-out;
-moz-transition: all 0.25s ease-out;
transition: all 0.25s ease-out;
}
.row-offcanvas-right
.sidebar-offcanvas {
right: -41.6%;
}
.row-offcanvas-left
.sidebar-offcanvas {
left: -41.6%;
}
.row-offcanvas-right.active {
right: 41.6%;
}
.row-offcanvas-left.active {
left: 41.6%;
}
.sidebar-offcanvas {
position: absolute;
top: 0;
width: 41.6%;
}
#sidebar {
padding-top:0;
}
}
Also, there are several more Bootstrap sidebar examples here
Bootstrap 4
Somebody wrote a blog post about this a few years back. There are examples in several languages, using both WebKit and Mozilla. There's also an example in Ruby.
It boils down to this: decide how wide you want your window to be; put a browser component in the window; wait until the page loads; capture the pixel buffer contents.

Bash has a feature called parameter expansion, which, among other things, allows string replacement based on so-called patterns (patterns resemble regular expressions, but there are fundamental differences and limitations). [flussence's original line: Bash has regular expressions, but they're well-hidden:]
The following demonstrates how to remove all white space (even from the interior) from a variable value.
$ var='abc def'
$ echo "$var"
abc def
# Note: flussence's original expression was "${var/ /}", which only replaced the *first* space char., wherever it appeared.
$ echo -n "${var//[[:space:]]/}"
abcdef
I had a similar problem. As you increase the line-height the space above the text increases. It's not padding but it will affect the vertical space between content. I found that adding a -ve top margin seemed to do the trick. It had to be done for all of the different instances of line-height and it varies with font-family too. Maybe this is something which designers need to be more aware of when passing design requirements (?) So for a particular instance of font-family and line-height:
h1 {
font-family: 'Garamond Premier Pro Regular';
font-size: 24px;
color: #001230;
line-height: 29px;
margin-top: -5px; /* CORRECTION FOR LINE-HEIGHT */
}

There are some changes in Xcode 8.0
Step 1:
Change scheme destination to Generic IOS device
.
Step 2:
Click Product
> Archive
> once this is complete open up the Organiser and click the latest version.
Step 3:
Click on Export...
option from right side of organiser window.
Step 4: Select a method for export > Choose correct signing > Save to Destination.
Xcode 10.0
Step 3: From Right Side Panel Click on Distribute App.
Step 4: Select Method of distribution and click next.
Step 5: It Opens up distribution option window. Select All compatible device variants and click next.
Step 6: Choose signing certificate.
Step 7: It will open up Preparing archive for distribution window. it takes few min.
Step 8: It will open up Archives window. Click on export and save it.
I deleted all my onedrive keys, installed latest preview etc and finally realized that the icons were working all along for some explorer directory views and not others.
In other words, medium, large, extra large, and tiles, but not list or detail. Since I don't want to learn all about how that works, I am just viewing my work directories as tiles for now.
When executable path has whitespace in system, call
#include<iostream>
using namespace std;
int main()
{
system("explorer C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe ");
system("pause");
return 0;
}
nohup node server.js > /dev/null 2>&1 &
nohup
means: Do not terminate this process even when the stty is cut
off.> /dev/null
means: stdout goes to /dev/null (which is a dummy
device that does not record any output). 2>&1
means: stderr also goes to the stdout (which is already redirected to /dev/null
). You may replace &1 with a file path to keep a log of errors, e.g.: 2>/tmp/myLog
&
at the end means: run this command as a background task.When you follow the above answer https://stackoverflow.com/a/10236938/6117565, you might get the error "No route to host".

To get .woff fonts first open the chrome dev tools panel (Ctrl+Shift+i
) go to Network and reload the page. There you will see everything the page downloads. Find the .woff file, right click and select Copy response.
The response will be a url so paste it in the navigation bar. A file will be downloaded, just add the .woff extension to it and voila.
I have the same problem. I have resolved the problem with following code:
app.use('/img',express.static(path.join(__dirname, 'public/images')));
app.use('/js',express.static(path.join(__dirname, 'public/javascripts')));
app.use('/css',express.static(path.join(__dirname, 'public/stylesheets')));

Microsoft recently modified the reflection API rendering most of these answers obsolete. The following should work on modern platforms (including Xamarin.Forms and UWP):
obj.GetType().GetTypeInfo().GetDeclaredMethod("MethodName").Invoke(obj, yourArgsHere);
Or as an extension method:
public static object InvokeMethod<T>(this T obj, string methodName, params object[] args)
{
var type = typeof(T);
var method = type.GetTypeInfo().GetDeclaredMethod(methodName);
return method.Invoke(obj, args);
}
Note:
If the desired method is in a superclass of obj
the T
generic must be explicitly set to the type of the superclass.
If the method is asynchronous you can use await (Task) obj.InvokeMethod(…)
.
After hours of searching and trying I found out that on a x64 server the MSOnline modules must be installed for x64, and some programs that need to run them are using the x86 PS version, so they will never find it.
[SOLUTION] What I did to solve the issue was:
Copy the folders called MSOnline
and MSOnline Extended
from the source
C:\Windows\System32\WindowsPowerShell\v1.0\Modules\
to the folder
C:\Windows\SysWOW64\WindowsPowerShell\v1.0\Modules\
And then in PS run the Import-Module MSOnline
, and it will automatically get the module :D
Try this
HTML
<textarea id="textarea" rows="8" cols="50" maxlength="100" ></textarea>
<div id="feedback"></div>
JS
$(document).ready(function() {
var max = 1000;
$('#feedback').html(max + 'characters remaining');
$('#textarea').keyup(function() {
var text_length = $('#textarea').val().length;
var text_remaining = max - text_length;
$('#feedback').html(text_remaining + ' characters remaining');
});
});
Using the base
package:
df <- data.frame(days = c(88, 11, 2, 5, 22, 1, 222, 2), name = c("Lynn", "Tom", "Chris", "Lisa", "Kyla", "Tom", "Lynn", "Lynn"))
# Three lines
target <- c("Tom", "Lynn")
index <- df$name %in% target
df[index, ]
# One line
df[df$name %in% c("Tom", "Lynn"), ]
Output:
days name
1 88 Lynn
2 11 Tom
6 1 Tom
7 222 Lynn
8 2 Lynn
Using sqldf
:
library(sqldf)
# Two alternatives:
sqldf('SELECT *
FROM df
WHERE name = "Tom" OR name = "Lynn"')
sqldf('SELECT *
FROM df
WHERE name IN ("Tom", "Lynn")')

useHistory
hook if you're using function componentsYou can use useHistory
hook to get history
instance.
import { useHistory } from "react-router-dom";
const MyComponent = () => {
const history = useHistory();
return (
<button onClick={() => history.push("/about")}>
Click me
</button>
);
}
The useHistory
hook gives you access to the history instance that you may use to navigate.
history
property inside page componentsReact Router injects some properties including history
to page components.
class HomePage extends React.Component {
render() {
const { history } = this.props;
return (
<div>
<button onClick={() => history.push("/projects")}>
Projects
</button>
</div>
);
}
}
withRouter
to inject router propertieswithRouter
wrapper injects router properties to components. For example you can use this wrapper to inject router to logout button component placed inside user menu.
import { withRouter } from "react-router";
const LogoutButton = withRouter(({ history }) => {
return (
<button onClick={() => history.push("/login")}>
Logout
</button>
);
});
export default LogoutButton;
It looks like CLR / C# might be getting better support for Vector<> soon.
See the Range.SpecialCells method. For example, to get cells with constant values or formulas use:
_xlWorksheet.UsedRange.SpecialCells(

Microsoft.Office.Interop.Excel.XlCellType.xlCellTypeFormulas)
Use this for unix if you are transferring using winscp or ftp:
public static void isFileReady(File entry) throws Exception {
long realFileSize = entry.length();
long currentFileSize = 0;
do {
try (FileInputStream fis = new FileInputStream(entry);) {
currentFileSize = 0;
while (fis.available() > 0) {
byte[] b = new byte[1024];
int nResult = fis.read(b);
currentFileSize += nResult;
if (nResult == -1)
break;
}
} catch (Exception e) {
e.printStackTrace();
}
System.out.println("currentFileSize=" + currentFileSize + ", realFileSize=" + realFileSize);
} while (currentFileSize != realFileSize);
}
A referral was returned from the server error usually means that the IP address is not hosted by the domain that is provided on the connection string. For more detail, see this link:
Referral was returned AD Provider
To illustrate the problem, we define two IP addresses hosted on different domains:
IP Address DC Name Notes
172.1.1.10 ozkary.com Production domain
172.1.30.50 ozkaryDev.com Development domain
If we defined a LDAP connection string with this format:
LDAP://172.1.1.10:389/OU=USERS,DC=OZKARYDEV,DC=COM
This will generate the error because the IP is actually on the OZKARY DC not the OZKARYDEV DC. To correct the problem, we would need to use the IP address that is associated to the domain.
Put the following in your .cs file:
using System.Linq;
You will then be able to use the following extension method from System.Linq.Enumerable:
public static TSource[] ToArray<TSource>(this System.Collections.Generic.IEnumerable<TSource> source)
I.e.
IEnumerable<object> query = ...;
object[] bob = query.ToArray();
public static int getDifferenceIndays(long timestamp1, long timestamp2) {
final int SECONDS = 60;
final int MINUTES = 60;
final int HOURS = 24;
final int MILLIES = 1000;
long temp;
if (timestamp1 < timestamp2) {
temp = timestamp1;
timestamp1 = timestamp2;
timestamp2 = temp;
}
Calendar startDate = Calendar.getInstance(TimeZone.getDefault());
Calendar endDate = Calendar.getInstance(TimeZone.getDefault());
endDate.setTimeInMillis(timestamp1);
startDate.setTimeInMillis(timestamp2);
if ((timestamp1 - timestamp2) < 1 * HOURS * MINUTES * SECONDS * MILLIES) {
int day1 = endDate.get(Calendar.DAY_OF_MONTH);
int day2 = startDate.get(Calendar.DAY_OF_MONTH);
if (day1 == day2) {
return 0;
} else {
return 1;
}
}
int diffDays = 0;
startDate.add(Calendar.DAY_OF_MONTH, diffDays);
while (startDate.before(endDate)) {
startDate.add(Calendar.DAY_OF_MONTH, 1);
diffDays++;
}
return diffDays;
}
Worked for me..
$timestamp = strtotime('10:09') + 60*60;
$time = date('H:i', $timestamp);
echo $time;//11:09
Explanation:
strtotime('10:09')
creates a numerical timestamp in seconds, something like 1510450372
. Simply add or remove the amount of seconds you need and use date()
to convert it back into a human readable format.
$timestamp = strtotime('10:09') + 60*60; // 10:09 + 1 hour
$timestamp = strtotime('10:09') + 60*60*2; // 10:09 + 2 hours
$timestamp = strtotime('10:09') - 60*60; // 10:09 - 1 hour
time()
also creates a numerical timestamp but for right now. You can use it in the same way.
$timestamp = time() + 60*60; // now + 1 hour
A simple solution that springs to mind is to have a String
block of spaces:
String indent = " "; // 20 spaces.
When printing out a string, compute the actual indent and add it to the end:
String output = "Newspaper";
output += indent.substring(0, indent.length - output.length);
This will mediate the number of spaces to the string, and put them all in the same column.
Setting the tz
attribute of the index explicitly seems to work:
ts_utc = ts.tz_convert("UTC")
ts_utc.index.tz = None
Simple! The folder named ..
is the parent folder, so you can make the path to the file you need as such
var foobar = require('../config/dev/foobar.json');
If you needed to go up two levels, you would write ../../
etc

Additional musings. You said insmod crashes. Insmod loads modules. The modules are built in another compile operation from building the kernel. Kernel and modules have to be built from the same headers and so forth. Are all the modules built during the kernel build, or are they "existing"?
The other idea, and something I know little about, is svn externals, which (if used) can affect what is checked out to your project. Look and see if this is any different when exporting.
Below solution will work for sure:

My team ran into this problem when using Node with React Native and PouchDB. Here is how we solved it...
NPM install buffer:
$ npm install --save buffer
Ensure Buffer
, btoa
, and atob
are loaded as a globals:
global.Buffer = global.Buffer || require('buffer').Buffer;
if (typeof btoa === 'undefined') {
global.btoa = function (str) {
return new Buffer(str, 'binary').toString('base64');
};
}
if (typeof atob === 'undefined') {
global.atob = function (b64Encoded) {
return new Buffer(b64Encoded, 'base64').toString('binary');
};
}
If you just want to get the current UNIX timestamp I'd just use time()
$timestamp = time();
clean
is its own build lifecycle phase (which can be thought of as an action or task) in Maven. mvn clean install
tells Maven to do the clean
phase in each module before running the install
phase for each module.
What this does is clear any compiled files you have, making sure that you're really compiling each module from scratch.
First of all, you would have to allocate memory:
char * S = new char[R.length() + 1];
then you can use strcpy
with S
and R.c_str()
:
std::strcpy(S,R.c_str());
You can also use R.c_str()
if the string doesn't get changed or the c string is only used once. However, if S
is going to be modified, you should copy the string, as writing to R.c_str()
results in undefined behavior.
Note: Instead of strcpy
you can also use str::copy
.
Actually, Double.NaN
is supported in all .NET versions 2.0 and greater.
