All mentioned comments above are great, sharing the path that worked with me for this Blacklist file that need to be edited:

The spec files are unit tests for your source files. The convention for Angular applications is to have a .spec.ts file for each .ts file. They are run using the Jasmine javascript test framework through the Karma test runner (https://karma-runner.github.io/) when you use the ng test
command.
You can use this for some further reading:
ansible-playbok -i <inventory> <playbook-name> -e "proc_name=sshd"
You can use the above command in below playbooks.

For Spring 5.2+ this works for me:

.map(uri -> ResponseEntity.noContent().<Void>build())
.orElse(ResponseEntity.notFound().build());
}
I'm using Django CMS 3.4 with Django 1.8. I stepped through the root cause in the Django CMS code. Root cause is the Django CMS is not changing directory to the directory with file containing the SQLite3 database before making database calls. The error message is spurious. The underlying problem is that a SQLite database call is made in the wrong directory.
The workaround is to ensure all your Django applications change directory back to the Django Project root directory when changing to working directories.
Route::get('/', function () {
return view('greeting', ['name' => 'James']);
});
<html>
<body>
<h1>Hello, {{ $name }}</h1>
</body>
</html>
or
public function index($id)
{
$category = Category::find($id);
$topics = $category->getTopicPaginator();
$message = Message::find(1);
// here I would just use "->with([$category, $topics, $message])"
return View::make('category.index')->with(compact('category', 'topics', 'message'));
}
Command like this :
composer.phar require intervention/image
error: composer.phar: command not found
I solved the problem by following this process
i set the composer globally and renamed composer.phar
to composer
then run this command composer require intervention/image
. and now it's working fine
Assume the following scenario:
composer.json
"parsecsv/php-parsecsv": "0.*"
composer.lock file
"name": "parsecsv/php-parsecsv",
"version": "0.1.4",
Latest release is
1.1.0
. The latest0.*
release is0.3.2
install: composer install parsecsv/php-parsecsv
This will install version 0.1.4
as specified in the lock file
update: composer update parsecsv/php-parsecsv
This will update the package to 0.3.2
. The highest version with respect to your composer.json. The entry in composer.lock
will be updated.
require: composer require parsecsv/php-parsecsv
This will update or install the newest version 1.1.0
. Your composer.lock
file and composer.json
file will be updated as well.
List installed dependencies:
composer show -i
composer show -i -t
-i
short for --installed
.
-t
short for --tree
.
I had a similar problem. I was working on a project where I did not control the web.xml configuration file, so I could not use the changes suggested about altering the version. Of course the project was not using JSF so this was especially annoying for me.
I found that there is a really simple fix. Go to Preferences > Maven > Java EE Itegration and uncheck the "JSF Configurator" box.
I did this in a fresh workspace before importing the project again, but it may work equally as well on an existing project ... not sure.
Simple for three dots

android:maxLines="2" <!--count your line>

While git clean
works well, I still find it useful to use my own script to clean the git repo, it has some advantages.
This shows a list of files to be cleaned, then interactively prompts to clean or not. This is nearly always what I want since interactively prompting per file gets tedious.
It also allows manual filtering of the list which comes in handy when there are file types you don't want to clean (and have reason not to commit).
git_clean.sh
#!/bin/bash
readarray -t -d '' FILES < <(
git ls-files -z --other --directory |
grep --null-data --null -v '.bin$\|Cargo.lock$'
)
if [ "$FILES" = "" ]; then
echo "Nothing to clean!"
exit 0
fi
echo "Dirty files:"
printf ' %s\n' "${FILES[@]}"
DO_REMOVE=0
while true; do
echo ""
read -p "Remove ${#FILES[@]} files? [y/n]: " choice
case "$choice" in
y|Y )
DO_REMOVE=1
break ;;
n|N )
echo "Exiting!"
break ;;
* ) echo "Invalid input, expected [Y/y/N/n]"
continue ;;
esac
done
if [ "$DO_REMOVE" -eq 1 ];then
echo "Removing!"
for f in "${FILES[@]}"; do
rm -rfv "$f"
done
fi
I output my Testresults HTML based, in this case it was helpfull to flush the content:
var_dump($array);
ob_flush();
There is a second PHP Method
flush()
which i not has tried.
With Nginx you can take advantage of the "x-forwarded-proto" header:
function ensureSec(req, res, next){
if (req.headers["x-forwarded-proto"] === "https"){
return next();
}
res.redirect("https://" + req.headers.host + req.url);
}
Updating since these answers are slightly outdated (although some still apply).
Simple feature added in rails 2.3.4, db/seeds.rb
Provides a new rake task
rake db:seed
Good for populating common static records like states, countries, etc...
http://railscasts.com/episodes/179-seed-data
*Note that you can use fixtures if you had already created them to also populate with the db:seed task by putting the following in your seeds.rb file (from the railscast episode):
require 'active_record/fixtures'
Fixtures.create_fixtures("#{Rails.root}/test/fixtures", "operating_systems")
For Rails 3.x use 'ActiveRecord::Fixtures' instead of 'Fixtures' constant
require 'active_record/fixtures'
ActiveRecord::Fixtures.create_fixtures("#{Rails.root}/test/fixtures", "fixtures_file_name")
I experienced the same as above after removing signing of assemblies in the solution. The projects would not build.
I found that one of the projects referenced the StrongNamer NuGet package, which modifies the build process and tries to sign non-signed Nuget packages.
After removing the StrongNamer package I was able to build the project again without signing/strong-naming the assemblies.
Guys use this code for adding nodes and childnodes for TreeView from C# code. *
KISS (Keep It Simple & Stupid :)*
protected void Button1_Click(object sender, EventArgs e)
{
TreeNode a1 = new TreeNode("Apple");
TreeNode b1 = new TreeNode("Banana");
TreeNode a2 = new TreeNode("gree apple");
TreeView2.Nodes.Add(a1);
TreeView2.Nodes.Add(b1);
a1.ChildNodes.Add(a2);
}
This is one of the ways that just came to mind:
combo1.Items.Add(new ListItem("Text", "Value"))
And to change text of or value of an item, you can do it like this:
combo1.Items[0].Text = 'new Text';
combo1.Items[0].Value = 'new Value';
There is no class called ListItem in Windows Forms. It only exists in ASP.NET, so you will need to write your own class before using it, the same as @Adam Markowitz did in his answer.

On a MacBook Pro running Mavericks, sysctl -a | grep hw.cpu
will only return some cryptic details. Much more detailed and accessible information is revealed in the machdep.cpu
section, ie:
sysctl -a | grep machdep.cpu
In particular, for processors with HyperThreading
(HT), you'll see the total enumerated CPU count (logical_per_package
) as double that of the physical core count (cores_per_package
).
sysctl -a | grep machdep.cpu | grep per_package
// 2. Select a database to use
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
die("Database selection failed: " . mysqli_error($connection));
}
You got the order of the arguments to mysqli_select_db()
backwards. And mysqli_error()
requires you to provide a connection argument. mysqli_XXX is not like mysql_XXX, these arguments are no longer optional.
Note also that with mysqli you can specify the DB in mysqli_connect()
:
$connection = mysqli_connect(DB_SERVER, DB_USER, DB_PASS, DB_NAME);
if (!$connection) {
die("Database connection failed: " . mysqli_connect_error();
}
You must use mysqli_connect_error()
, not mysqli_error()
, to get the error from mysqli_connect()
, since the latter requires you to supply a valid connection.
I did a fun hack to solve this issue to my satisfaction. I've got an AJAX site that loads content dynamically, then modifies the window.location.hash, and I had code to run upon $(document).ready() to parse the hash and load the appropriate section. The thing is that I was perfectly happy with my section loading code for navigation, but wanted to add a way to intercept the browser back and forward buttons, which change the window location, but not interfere with my current page loading routines where I manipulate the window.location, and polling the window.location at constant intervals was out of the question.
What I ended up doing was creating an object as such:
var pageload = {
ignorehashchange: false,
loadUrl: function(){
if (pageload.ignorehashchange == false){
//code to parse window.location.hash and load content
};
}
};
Then, I added a line to my site script to run the pageload.loadUrl
function upon the hashchange event, as such:
window.addEventListener("hashchange", pageload.loadUrl, false);
Then, any time I want to modify the window.location.hash
without triggering this page loading routine, I simply add the following line before each window.location.hash =
line:
pageload.ignorehashchange = true;
and then the following line after each hash modification line:
setTimeout(function(){pageload.ignorehashchange = false;}, 100);
So now my section loading routines are usually running, but if the user hits the 'back' or 'forward' buttons, the new location is parsed and the appropriate section loaded.
Use this approach to sum the list of BigDecimal:
List<BigDecimal> values = ... // List of BigDecimal objects
BigDecimal sum = values.stream().reduce((x, y) -> x.add(y)).get();
This approach maps each BigDecimal as a BigDecimal only and reduces them by summing them, which is then returned using the get()
method.
Here's another simple way to do the same summing:
List<BigDecimal> values = ... // List of BigDecimal objects
BigDecimal sum = values.stream().reduce(BigDecimal::add).get();
Update
If I were to write the class and lambda expression in the edited question, I would have written it as follows:
import java.math.BigDecimal;
import java.util.LinkedList;
public class Demo
{
public static void main(String[] args)
{
LinkedList<Invoice> invoices = new LinkedList<>();
invoices.add(new Invoice("C1", "I-001", BigDecimal.valueOf(.1), BigDecimal.valueOf(10)));
invoices.add(new Invoice("C2", "I-002", BigDecimal.valueOf(.7), BigDecimal.valueOf(13)));
invoices.add(new Invoice("C3", "I-003", BigDecimal.valueOf(2.3), BigDecimal.valueOf(8)));
invoices.add(new Invoice("C4", "I-004", BigDecimal.valueOf(1.2), BigDecimal.valueOf(7)));
// Java 8 approach, using Method Reference for mapping purposes.
invoices.stream().map(Invoice::total).forEach(System.out::println);
System.out.println("Sum = " + invoices.stream().map(Invoice::total).reduce((x, y) -> x.add(y)).get());
}
// This is just my style of writing classes. Yours can differ.
static class Invoice
{
private String company;
private String number;
private BigDecimal unitPrice;
private BigDecimal quantity;
public Invoice()
{
unitPrice = quantity = BigDecimal.ZERO;
}
public Invoice(String company, String number, BigDecimal unitPrice, BigDecimal quantity)
{
setCompany(company);
setNumber(number);
setUnitPrice(unitPrice);
setQuantity(quantity);
}
public BigDecimal total()
{
return unitPrice.multiply(quantity);
}
public String getCompany()
{
return company;
}
public void setCompany(String company)
{
this.company = company;
}
public String getNumber()
{
return number;
}
public void setNumber(String number)
{
this.number = number;
}
public BigDecimal getUnitPrice()
{
return unitPrice;
}
public void setUnitPrice(BigDecimal unitPrice)
{
this.unitPrice = unitPrice;
}
public BigDecimal getQuantity()
{
return quantity;
}
public void setQuantity(BigDecimal quantity)
{
this.quantity = quantity;
}
}
}
(Note: root, base, apex domains are all the same thing. Using interchangeably for google-foo.)
Traditionally, to point your apex domain you'd use an A record pointing to your server's IP. This solution doesn't scale and isn't viable for a cloud platform like Heroku, where multiple and frequently changing backends are responsible for responding to requests.
For subdomains (like www.example.com
) you can use CNAME records pointing to your-app-name.herokuapp.com
. From there on, Heroku manages the dynamic A records behind your-app-name.herokuapp.com
so that they're always up-to-date. Unfortunately, the DNS specification does not allow CNAME records on the zone apex (the base domain). (For example, MX records would break as the CNAME would be followed to its target first.)
Back to root domains, the simple and generic solution is to not use them at all. As a fallback measure, some DNS providers offer to setup an HTTP redirect for you. In that case, set it up so that example.com
is an HTTP redirect to www.example.com
.
Some DNS providers have come forward with custom solutions that allow CNAME-like behavior on the zone apex. To my knowledge, we have DNSimple's ALIAS record and DNS Made Easy's ANAME record; both behave similarly.
Using those, you could setup your records as (using zonefile notation, even tho you'll probably do this on their web user interface):
@ IN ALIAS your-app-name.herokuapp.com.
www IN CNAME your-app-name.herokuapp.com.
Remember @
here is a shorthand for the root domain (example.com
). Also mind you that the trailing dots are important, both in zonefiles, and some web user interfaces.
Amazon's Route 53 also has an ALIAS record type, but it's somewhat limited, in that it only works to point within AWS. At the moment I would not recommend using this for a Heroku setup.
Some people confuse DNS providers with domain name registrars, as there's a bit of overlap with companies offering both. Mind you that to switch your DNS over to one of the aforementioned providers, you only need to update your nameserver records with your current domain registrar. You do not need to transfer your domain registration.

I've run into this need on several Joomla project. The simplest way I've found to address is to add a hidden input field to my template:
<input type="hidden" id="baseurl" name="baseurl" value="<?php echo $this->baseurl; ?>" />
When I need the value in JavaScript:
var baseurl = document.getElementById('baseurl').value;
Not as fancy as using pure JavaScript but simple and gets the job done.

Facelets is a XML based view technology which uses XHTML+XML to generate HTML output. XML has five special characters which has special treatment by the XML parser:
<
the start of a tag.>
the end of a tag."
the start and end of an attribute value.'
the alternative start and end of an attribute value.&
the start of an entity (which ends with ;
).In case of <
, the XML parser is implicitly looking for the tag name and the end tag >
. However, in your particular case, you were using <
as a JavaScript operator, not as an XML entity. This totally explains the XML parsing error you got:
The content of elements must consist of well-formed character data or markup.
In essence, you're writing JavaScript code in the wrong place, a XML document instead of a JS file, so you should be escaping all XML special characters accordingly. The <
must be escaped as <
.
So, essentially, the
for (var i = 0; i < length; i++) {
must become
for (var i = 0; i < length; i++) {
to make it XML-valid.
However, this makes the JavaScript code harder to read and maintain. As stated in Mozilla Developer Network's excellent document Writing JavaScript for XHTML, you should be placing the JavaScript code in a character data (CDATA) block. Thus, in JSF terms, that would be:
<h:outputScript>
<![CDATA[
// ...
]]>
</h:outputScript>
The XML parser will interpret the block's contents as "plain vanilla" character data and not as XML and hence interpret the XML special characters "as-is".
But, much better is to just put the JS code in its own JS file which you include by <script src>
, or in JSF terms, the <h:outputScript>
.
<h:outputScript name="functions.js" target="head" />
This way you don't need to worry about XML-special characters in your JS code. Additional advantage is that this gives the browser the opportunity to cache the JS file so that average response size is smaller.
I will suggest you to use below the library because it allows you to set default values in one file and you can use it everywhere in the project without making one line of change. https://github.com/Shahbaz89khan/ShadowView
If you are fine using a graphical tool this works very well:
gitk <file>
gitk now shows all commits where the file has been updated. Marking a commit will show you the diff against the previous commit in the list. This also works for directories, but then you also get to select the file to diff for the selected commit. Super useful!
country.code
is not in your group by
statement, and is not an aggregate (wrapped in an aggregate function).

This resizes the figure immediately even after the figure has been drawn (at least using Qt4Agg/TkAgg - but not MacOSX - with matplotlib 1.4.0):
matplotlib.pyplot.get_current_fig_manager().resize(width_px, height_px)
I didn't find any of the previous solutions to be adequate enough due to bad performance, so I made my own that uses simple math instead of looping. Should work fine in all browsers as well.
According to this performance test case it is much faster then the other solutions found here.

When you want to copy a sheet named "mySheet" and use .Copy After:=, Excel first names the copied sheet exactly the same and simply adds ' (2)' so that its final name is "mySheet (2)".
Hidden or Not, doesn't matter. It rocks with 2 lines of code, adding the copied sheet at the end of the Workbook!!!
Example:
Sheets("mySheet").Copy After:=Sheets(ThisWorkbook.Sheets.count)
Sheets("mySheet (2)").name = "TheNameYouWant"
Simple no!
After some experimentation I found that a fourth value in the line controls the spread (at least in FF 10). I opposed the vertical offsets and gave them a negative spread.

You might have them turned off in your gmail settings, heres the link to change them https://support.google.com/mail/answer/145919?hl=en
Also gmail may be blocking the images thinking they are suspicious.
from the link above.
How Gmail makes images safe
Some senders try to use externally linked images in harmful ways, but Gmail takes action to ensure that images are loaded safely. Gmail serves all images through Google’s image proxy servers and transcodes them before delivery to protect you in the following ways:
Senders can’t use image loading to get information like your IP address or location. Senders can’t set or read cookies in your browser. Gmail checks your images for known viruses or malware. In some cases, senders may be able to know whether an individual has opened a message with unique image links. As always, Gmail scans every message for suspicious content and if Gmail considers a sender or message potentially suspicious, images won’t be displayed and you’ll be asked whether you want to see the images.
The struct module mimics C structures. It takes more CPU cycles for a processor to read a 16-bit word on an odd address or a 32-bit dword on an address not divisible by 4, so structures add "pad bytes" to make structure members fall on natural boundaries. Consider:
struct { 11
char a; 012345678901
short b; ------------
char c; axbbcxxxdddd
int d;
};
This structure will occupy 12 bytes of memory (x being pad bytes).
Python works similarly (see the struct documentation):
>>> import struct
>>> struct.pack('BHBL',1,2,3,4)
'\x01\x00\x02\x00\x03\x00\x00\x00\x04\x00\x00\x00'
>>> struct.calcsize('BHBL')
12
Compilers usually have a way of eliminating padding. In Python, any of =<>! will eliminate padding:
>>> struct.calcsize('=BHBL')
8
>>> struct.pack('=BHBL',1,2,3,4)
'\x01\x02\x00\x03\x04\x00\x00\x00'
Beware of letting struct handle padding. In C, these structures:
struct A { struct B {
short a; int a;
char b; char b;
}; };
are typically 4 and 8 bytes, respectively. The padding occurs at the end of the structure in case the structures are used in an array. This keeps the 'a' members aligned on correct boundaries for structures later in the array. Python's struct module does not pad at the end:
>>> struct.pack('LB',1,2)
'\x01\x00\x00\x00\x02'
>>> struct.pack('LBLB',1,2,3,4)
'\x01\x00\x00\x00\x02\x00\x00\x00\x03\x00\x00\x00\x04'
Just in case you want to handle the behaviour of the back button (at the bottom of the phone) and the home button (the one to the left of the action bar), this custom activity I'm using in my project may help you.
import android.os.Bundle;

import android.support.v7.app.AppCompatActivity;
import android.view.MenuItem;
/**
* Activity where the home action bar button behaves like back by default

public class BackActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setupHomeButton();
}
private void setupHomeButton() {
final ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);
}
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {

Example of use in your activity:
public class SomeActivity extends BackActivity {
// ....
@Override
public void onBackPressed()
{
// Example of logic
if ( yourConditionToOverride ) {
// ... do your logic ...
} else {
super.onBackPressed();
}
}
}
this short code worked for me:
Configuration wConfig = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
ServiceModelSectionGroup wServiceSection = ServiceModelSectionGroup.GetSectionGroup(wConfig);
ClientSection wClientSection = wServiceSection.Client;
wClientSection.Endpoints[0].Address = <your address>;
wConfig.Save();
Of course you have to create the ServiceClient proxy AFTER the config has changed. You also need to reference the System.Configuration and System.ServiceModel assemblies to make this work.
Cheers
In the end, both do the same thing. There are some differences in code: Web Services doesn't add a Root namespace of project, but Service Reference adds service classes to the namespace of the project. The ServiceSoapClient
class gets a different naming, which is not important. In working with TFS I'd rather use Service Reference because it works better with source control. Both work with SOAP protocols.
I find it better to use the Service Reference because it is new and will thus be better maintained.

You can load data from a csv or text file. If you have a text file with records from a table, you can load those records within the table. For example if you have a text file, where each row is a record with the values for each column, you can load the records this way.
id //field 1
name //field2
1,peter
2,daniel
...
--example on windows
LOAD DATA LOCAL INFILE 'C:\\directory_example\\table.txt'
INTO TABLE Table
CHARACTER SET UTF8
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\r\n';

This would do the matching, if you only want to allow that just wrap it in ^$ or any other delimiters that you see appropriate, if you do this no specific disallow logic is needed.
You have to edit three files to set a permanent environment variable as follow:
When you open any terminal window this file will be run. Therefore, if you wish to have a permanent environment variable in all of your terminal windows you have to add the following line at the end of this file:
export DISPLAY=0
Same as bashrc you have to put the mentioned command line at the end of this file to have your environment variable in every login of your OS.
If you want your environment variable in every window or application (not just terminal window) you have to edit this file. Add the following command at the end of this file:
DISPLAY=0
Note that in this file you do not have to write export command
Normally you have to restart your computer to apply these changes. But you can apply changes in bashrc and profile by these commands:
$ source ~/.bashrc
$ source ~/.profile
But for /etc/environment you have no choice but restarting (as far as I know)
I've written a simple script for these procedures to do all those work. You just have to set the name and value of your environment variable.
#!/bin/bash
echo "Enter variable name: "
read variable_name
echo "Enter variable value: "
read variable_value
echo "adding " $variable_name " to environment variables: " $variable_value
echo "export "$variable_name"="$variable_value>>~/.bashrc
echo $variable_name"="$variable_value>>~/.profile
echo $variable_name"="$variable_value>>/etc/environment
source ~/.bashrc
source ~/.profile
echo "do you want to restart your computer to apply changes in /etc/environment file? yes(y)no(n)"
read restart
case $restart in
y) sudo shutdown -r 0;;
n) echo "don't forget to restart your computer manually";;
esac
exit
Save these lines in a shfile then make it executable and just run it!
You should check the parent process name, see The Code Project article about a .NET based solution**.
A non-programmatic way to check:
c:\windows\notepad.exe
)The same can be checked by getting the parent process name.
Simple Answer which worked for me:

I guess you cant, this maybe a limitation or not included in the IE browser. I have tried your jsfiddle with IE6-8 and all of it doesn't show the scrollbar and not sure with IE9. While in FF and chrome the scrollbar is shown. I also want to see how to do it in IE if possible.
If you really want to show the scrollbar, you can add a fake scrollbar. If you are familiar with some of the js library which use in RIA. Like in jquery/dojo some of the select is editable, because it is a combination of textbox + select or it can also be a textbox + div.
As an example, see it here a JavaScript that make select like editable.
If you want to avoid error cases, don't allow wc -l
to see files with newlines (which it will count as 2+ files)
e.g. Consider a case where we have a single file with a single EOL character in it
> mkdir emptydir && cd emptydir
> touch $'file with EOL(\n) character in it'
> find -type f
./file with EOL(?) character in it
> find -type f | wc -l
2
Since at least gnu wc
does not appear to have an option to read/count a null terminated list (except from a file), the easiest solution would just be to not pass it filenames, but a static output each time a file is found, e.g. in the same directory as above
> find -type f -exec printf '\n' \; | wc -l
1
Or if your find
supports it
> find -type f -printf '\n' | wc -l
1
You have one occult directory named ".metadata" in workspace directory. Close Eclipse, delete ".metadata" and open Eclipse. When eclipse ask you about workspace make sure that ".metadata" isn't in workspace directory and click "ok" button to select default workspace.
Modify to suit your specifics, or make more generic as needed:
Private Sub CopyItOver()
Set NewBook = Workbooks.Add
Workbooks("Whatever.xlsx").Worksheets("output").Range("A1:K10").Copy
NewBook.Worksheets("Sheet1").Range("A1").PasteSpecial (xlPasteValues)
NewBook.SaveAs FileName:=NewBook.Worksheets("Sheet1").Range("E3").Value
End Sub
To be compliant with all browsers you should always declare the input type.
Some browsers will assume default type as 'text', but this isn't a good practice.

SELECT CONVERT(NVARCHAR(10), PaymentDate, 120) [Month], SUM(Amount) [TotalAmount]
FROM Payments
GROUP BY CONVERT(NVARCHAR(10), PaymentDate, 120)
ORDER BY [Month]
You could also try:
SELECT DATEPART(Year, PaymentDate) Year, DATEPART(Month, PaymentDate) Month, SUM(Amount) [TotalAmount]
FROM Payments
GROUP BY DATEPART(Year, PaymentDate), DATEPART(Month, PaymentDate)
ORDER BY Year, Month
Wouldn't it just be a case of:
ArrayList<ArrayList<String>> outer = new ArrayList<ArrayList<String>>();
ArrayList<String> nodeList = new ArrayList<String>();
// Fill in nodeList here...
outer.add(nodeList);
Repeat as necesary.
This should return you a list in the format you specified.
The first version is preferable:
{1: 'one', 2: 'two'}
. The second variant only works for (some) string keys. Using different kinds of syntax depending on the type of the keys would be an unnecessary inconsistency.It is faster:
$ python -m timeit "dict(a='value', another='value')"
1000000 loops, best of 3: 0.79 usec per loop
$ python -m timeit "{'a': 'value','another': 'value'}"
1000000 loops, best of 3: 0.305 usec per loop

One liner if you are using RxJava & RxBindings. Similar approach without the boilerplate. This also solves the hack to suppress warnings as in the answer by Tim Autin.
RxView.layoutChanges(yourView).take(1)
.subscribe(aVoid -> {
// width and height have been calculated here
});
This is it. No need to be unsubscribe, even if never called.

It's a good practice to make all the images in vector based format so you can resize them easily using a vector design software like Illustrator etc..
To display it in ls -lh
format, use:
(du -sh ./*; ls -lh --color=no) | awk '{ if($1 == "total") {X = 1} else if (!X) {SIZES[$2] = $1} else { sub($5 "[ ]*", sprintf("%-7s ", SIZES["./" $9]), $0); print $0} }'
Awk code explained:
if($1 == "total") { // Set X when start of ls is detected
X = 1
} else if (!X) { // Until X is set, collect the sizes from `du`
SIZES[$2] = $1
} else {
// Replace the size on current current line (with alignment)
sub($5 "[ ]*", sprintf("%-7s ", SIZES["./" $9]), $0);
print $0
}
Sample output:

I had the same sort of need and found this to work well for me (postgres 8.4):
CAST((COALESCE(myfield,'0')) AS INTEGER)
Some test cases to demonstrate:
db=> select CAST((COALESCE(NULL,'0')) AS INTEGER);
int4
------
0
(1 row)
db=> select CAST((COALESCE('','0')) AS INTEGER);
int4
------
0
(1 row)
db=> select CAST((COALESCE('4','0')) AS INTEGER);
int4
------
4
(1 row)
db=> select CAST((COALESCE('bad','0')) AS INTEGER);
ERROR: invalid input syntax for integer: "bad"
If you need to handle the possibility of the field having non-numeric text (such as "100bad") you can use regexp_replace to strip non-numeric characters before the cast.
CAST(REGEXP_REPLACE(COALESCE(myfield,'0'), '[^0-9]+', '', 'g') AS INTEGER)
Then text/varchar values like "b3ad5" will also give numbers
db=> select CAST(REGEXP_REPLACE(COALESCE('b3ad5','0'), '[^0-9]+', '', 'g') AS INTEGER);
regexp_replace
----------------
35
(1 row)
To address Chris Cogdon's concern with the solution not giving 0 for all cases, including a case such as "bad" (no digit characters at all), I made this adjusted statement:
CAST((COALESCE(NULLIF(REGEXP_REPLACE(myfield, '[^0-9]+', '', 'g'), ''), '0')) AS INTEGER);
It works similar to the simpler solutions, except will give 0 when the value to convert is non-digit characters only, such as "bad":
db=> select CAST((COALESCE(NULLIF(REGEXP_REPLACE('no longer bad!', '[^0-9]+', '', 'g'), ''), '0')) AS INTEGER);
coalesce
----------
0
(1 row)
OK, I've solved this with some help from ES support. Issue the following command to the API on all nodes (or the nodes you believe to be the cause of the problem):
curl -XPUT 'localhost:9200/<index>/_settings' \
-d '{"index.routing.allocation.disable_allocation": false}'
where <index>
is the index you believe to be the culprit. If you have no idea, just run this on all nodes:
curl -XPUT 'localhost:9200/_settings' \
-d '{"index.routing.allocation.disable_allocation": false}'
I also added this line to my yaml config and since then, any restarts of the server/service have been problem free. The shards re-allocated back immediately.
FWIW, to answer an oft sought after question, set MAX_HEAP_SIZE to 30G unless your machine has less than 60G RAM, in which case set it to half the available memory.
Personally, I use ... | Out-Null
because, as others have commented, that looks like the more "PowerShellish" approach compared to ... > $null
and [void] ...
. $null = ...
is exploiting a specific automatic variable and can be easy to overlook, whereas the other methods make it obvious with additional syntax that you intend to discard the output of an expression. Because ... | Out-Null
and ... > $null
come at the end of the expression I think they effectively communicate "take everything we've done up to this point and throw it away", plus you can comment them out easier for debugging purposes (e.g. ... # | Out-Null
), compared to putting $null =
or [void]
before the expression to determine what happens after executing it.
Let's look at a different benchmark, though: not the amount of time it takes to execute each option, but the amount of time it takes to figure out what each option does. Having worked in environments with colleagues who were not experienced with PowerShell or even scripting at all, I tend to try to write my scripts in a way that someone coming along years later that might not even understand the language they're looking at can have a fighting chance at figuring out what it's doing since they might be in a position of having to support or replace it. This has never occurred to me as a reason to use one method over the others until now, but imagine you're in that position and you use the help
command or your favorite search engine to try to find out what Out-Null
does. You get a useful result immediately, right? Now try to do the same with [void]
and $null =
. Not so easy, is it?
Granted, suppressing the output of a value is a pretty minor detail compared to understanding the overall logic of a script, and you can only try to "dumb down" your code so much before you're trading your ability to write good code for a novice's ability to read...not-so-good code. My point is, it's possible that some who are fluent in PowerShell aren't even familiar with [void]
, $null =
, etc., and just because those may execute faster or take less keystrokes to type, doesn't mean they're the best way to do what you're trying to do, and just because a language gives you quirky syntax doesn't mean you should use it instead of something clearer and better-known.*
* I am presuming that Out-Null
is clear and well-known, which I don't know to be $true
. Whichever option you feel is clearest and most accessible to future readers and editors of your code (yourself included), regardless of time-to-type or time-to-execute, that's the option I'm recommending you use.

Work with checkboxes using observables
You could even choose to use a behaviourSubject
to utilize the power of observables so you can start a certain chain of reaction starting at the isChecked$
observable.
In your component.ts:
public isChecked$ = new BehaviorSubject(false);
toggleChecked() {
this.isChecked$.next(!this.isChecked$.value)
}
In your template
<input type="checkbox" [checked]="isChecked$ | async" (change)="toggleChecked()">

What about you declare the following "Key" class:
public class Key {
public Object key1, key2, ..., keyN;
public Key(Object key1, Object key2, ..., Object keyN) {
this.key1 = key1;
this.key2 = key2;
...
this.keyN = keyN;
}
@Override
public boolean equals(Object obj) {
if (!(obj instanceof Key))
return false;
Key ref = (Key) obj;
return this.key1.equals(ref.key1) &&
this.key2.equals(ref.key2) &&
...
this.keyN.equals(ref.keyN)
}
@Override
public int hashCode() {
return key1.hashCode() ^ key2.hashCode() ^
... ^ keyN.hashCode();
}
}
Declaring the Map
Map<Key, Double> map = new HashMap<Key,Double>();
Declaring the key object
Key key = new Key(key1, key2, ..., keyN)
Filling the map
map.put(key, new Double(0))
Getting the object from the map
Double result = map.get(key);
I have not compiled this as it is meant for a proof of concept. This is how I have implemented a Progress bar for database access in the past. This example shows access to a SQLite database using the System.Data.SQLite module
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
// Get the BackgroundWorker that raised this event.
BackgroundWorker worker = sender as BackgroundWorker;
using(SQLiteConnection cnn = new SQLiteConnection("Data Source=MyDatabase.db"))
{
cnn.Open();
int TotalQuerySize = GetQueryCount("Query", cnn); // This needs to be implemented and is not shown in example
using (SQLiteCommand cmd = cnn.CreateCommand())
{
cmd.CommandText = "Query is here";
using(SQLiteDataReader reader = cmd.ExecuteReader())
{
int i = 0;
while(reader.Read())
{
// Access the database data using the reader[]. Each .Read() provides the next Row
if(worker.WorkerReportsProgress) worker.ReportProgress(++i * 100/ TotalQuerySize);
}
}
}
}
}
private void backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
{
this.progressBar1.Value = e.ProgressPercentage;
}
private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
// Notify someone that the database access is finished. Do stuff to clean up if needed
// This could be a good time to hide, clear or do somthign to the progress bar
}
public void AcessMySQLiteDatabase()
{
BackgroundWorker backgroundWorker1 = new BackgroundWorker();
backgroundWorker1.DoWork +=
new DoWorkEventHandler(backgroundWorker1_DoWork);
backgroundWorker1.RunWorkerCompleted +=
new RunWorkerCompletedEventHandler(

Use ifelse
df %>%
mutate(g = ifelse(a == 2 | a == 5 | a == 7 | (a == 1 & b == 4), 2,
ifelse(a == 0 | a == 1 | a == 4 | a == 3 | c == 4, 3, NA)))
Added - if_else: Note that in dplyr 0.5 there is an if_else
function defined so an alternative would be to replace ifelse
with if_else
; however, note that since if_else
is stricter than ifelse
(both legs of the condition must have the same type) so the NA
in that case would have to be replaced with NA_real_
.
df %>%
mutate(g = if_else(a == 2 | a == 5 | a == 7 | (a == 1 & b == 4), 2,
if_else(a == 0 | a == 1 | a == 4 | a == 3 | c == 4, 3, NA_real_)))
Added - case_when Since this question was posted dplyr has added case_when
so another alternative would be:
df %>% mutate(g = case_when(a == 2 | a == 5 | a == 7 | (a == 1 & b == 4) ~ 2,
a == 0 | a == 1 | a == 4 | a == 3 | c == 4 ~ 3,
TRUE ~ NA_real_))
Added - arithmetic/na_if If the values are numeric and the conditions (except for the default value of NA at the end) are mutually exclusive, as is the case in the question, then we can use an arithmetic expression such that each term is multiplied by the desired result using na_if
at the end to replace 0 with NA.
df %>%
mutate(g = 2 * (a == 2 | a == 5 | a == 7 | (a == 1 & b == 4)) +
3 * (a == 0 | a == 1 | a == 4 | a == 3 | c == 4),
g = na_if(g, 0))
Just you need to desc with asc. Write the query like below. It will return the values in ascending order.
SELECT * FROM table GROUP BY m_id ORDER BY m_id asc;
To check whether select box has any values:
if( $('#fruit_name').has('option').length > 0 ) {
To check whether selected value is empty:
if( !$('#fruit_name').val() ) {
We can simply declare more than one Controller in the same module. Here's an example:

Use the somewhat hidden security feature:
pip install requests[security]
or
pip install pyOpenSSL ndg-httpsclient pyasn1
Both commands install following extra packages:
Please note that this is not required for python-2.7.9+.
If pip install
fails with errors, check whether you have required development packages for libffi
, libssl
and python
installed in your system using distribution's package manager:
Debian/Ubuntu - python-dev
libffi-dev
libssl-dev
packages.
Fedora - openssl-devel
python-devel
libffi-devel
packages.
Distro list above is incomplete.
Workaround (see the original answer by @TomDotTom):
In case you cannot install some of the required development packages, there's also an option to disable that warning:
import requests.packages.urllib3
requests.packages.urllib3.disable_warnings()
If your pip
itself is affected by InsecurePlatformWarning
and cannot install anything from PyPI, it can be fixed with this step-by-step guide to deploy extra python packages manually.
You can use CSS to do it for example

I did the test (but it is not your example) and the data does not return them orderly or complete
>>> ind = ['p5','p1','p8','p4','p2','p8']
>>> newind = {x.replace('p','') for x in ind}
>>> newind
{'1', '2', '8', '5', '4'}
I proved that this works:
>>> ind = ['p5','p1','p8','p4','p2','p8']
>>> newind = [x.replace('p','') for x in ind]
>>> newind
['5', '1', '8', '4', '2', '8']
or
>>> newind = []
>>> ind = ['p5','p1','p8','p4','p2','p8']
>>> for x in ind:
... newind.append(x.replace('p',''))
>>> newind
['5', '1', '8', '4', '2', '8']

Adding to Ophirs answer, JsonFormat is available even before protobuf 3.0. However, the way to do it differs a little bit.
In Protobuf 3.0+, the JsonFormat class is a singleton and therefore do something like the below
String jsonString = "";
JsonFormat.parser().ignoringUnknownFields().merge(jsonString,yourObjectBuilder);
In Protobuf 2.5+, the below should work
String jsonString = "";
JsonFormat jsonFormat = new JsonFormat();
jsonString = jsonFormat.printToString(yourProtobufMessage);
Here is a link to a tutorial I wrote that uses the JsonFormat class in a TypeAdapter that can be registered to a GsonBuilder object. You can then use Gson's toJson and fromJson methods to convert the proto data to Java and back.
Replying to jean . If we have the protobuf data in a file and want to parse it into a protobuf message object, use the merge method TextFormat class. See the below snippet:
// Let your proto text data be in a file MessageDataAsProto.prototxt
// Read it into string
String protoDataAsString = FileUtils.readFileToString(new File("MessageDataAsProto.prototxt"));
// Create an object of the message builder
MyMessage.Builder myMsgBuilder = MyMessage.newBuilder();
// Use text format to parse the data into the message builder
TextFormat.merge(protoDataAsString, ExtensionRegistry.getEmptyRegistry(), myMsgBuilder);
// Build the message and return
return myMsgBuilder.build();
IMHO the best place to find this information is: http://code.google.com/p/yahoo-finance-managed/
I used to use the "gummy-stuff" too but then I found this page which is far more organized and full of easy to use examples. I am using it now to get the data in CSV files and use the files in my C++/Qt project.
When you are only dealing with a single table anyway, the biggest practical difference I have found is that DataSet has a "HasChanges" method but DataTable does not. Both have a "GetChanges" however, so you can use that and test for null.
They should have the same time, the update is supposed to be atomic, meaning that whatever how long it takes to perform, the action is supposed to occurs as if all was done at the same time.
If you're experiencing a different behaviour, it's time to change for another DBMS.
Assuming we can use some ES6 syntax like the spread operator, we'll want to do something as many times as the sum of all numbers in the collection.
In this case if times is equal to [1,2,3]
, the total number of times will be 6, i.e. 1+2+3.
/**
* @param {number[]} times
* @param {cb} function
*/
function doTimes(times, cb) {
// Get the sum of all the times
const totalTimes = times.reduce((acc, time) => acc + time);
// Call the callback as many times as the sum
[...Array(totalTimes)].map(cb);
}
doTimes([1,2,3], () => console.log('something'));
// => Prints 'something' 6 times
This post should be helpful if the logic behind constructing and spreading an array isn't apparent.
I use this syntax for flexibility and speed -
begin
--
with KLUJ as
( select 0 ROES from dual
union
select count(*) from MY_TABLE where rownum = 1
) select max(ROES) into has_rows from KLUJ;
--
end;
Dual returns 1 row, rownum adds 0 or 1 rows, and max() groups to exactly 1. This gives 0 for no rows in a table and 1 for any other number of rows.
I extend the where clause to count rows by condition, remove rownum to count rows meeting a condition, and increase rownum to count rows meeting the condition up to a limit.

When it comes to Muhammad Mehdi's answer, it is better to do:
private void salary_texbox_PreviewTextInput(object sender, TextCompositionEventArgs e)
{
Regex regex = new Regex ( "[^0-9]+" );
if(regex.IsMatch(e.Text))
{
MessageBox.Show("Error");
}
}
Because when comparing with the TextCompositionEventArgs it gets also the last character, while with the textbox.Text it does not. With textbox, the error will show after next inserted character.
A DateTime
in C# is a value type, not a reference type, and therefore cannot be null. It can however be the constant DateTime.MinValue
which is outside the range of Sql Servers DATETIME
data type.
Value types are guaranteed to always have a (default) value (of zero) without always needing to be explicitly set (in this case DateTime.MinValue).
Conclusion is you probably have an unset DateTime value that you are trying to pass to the database.
DateTime.MinValue = 1/1/0001 12:00:00 AM
DateTime.MaxValue = 23:59:59.9999999, December 31, 9999,
exactly one 100-nanosecond tick
before 00:00:00, January 1, 10000
MSDN: DateTime.MinValue
Regarding Sql Server
datetime
Date and time data from January 1, 1753 through December 31, 9999, to an accuracy of one three-hundredth of a second (equivalent to 3.33 milliseconds or 0.00333 seconds). Values are rounded to increments of .000, .003, or .007 secondssmalldatetime
Date and time data from January 1, 1900, through June 6, 2079, with accuracy to the minute. smalldatetime values with 29.998 seconds or lower are rounded down to the nearest minute; values with 29.999 seconds or higher are rounded up to the nearest minute.
MSDN: Sql Server DateTime and SmallDateTime
Lastly, if you find yourself passing a C# DateTime
as a string to sql, you need to format it as follows to retain maximum precision and to prevent sql server from throwing a similar error.
string sqlTimeAsString = myDateTime.ToString("yyyy-MM-ddTHH:mm:ss.fff");
Update (8 years later)
Consider using the sql DateTime2
datatype which aligns better with the .net DateTime
with date range 0001-01-01 through 9999-12-31
and time range 00:00:00 through 23:59:59.9999999
string dateTime2String = myDateTime.ToString("yyyy-MM-ddTHH:mm:ss.fffffff");
Using reduce we can verify if each path exists and create it if necessary, also this way I think it is easier to follow. Edited, thanks @Arvin, we should use path.sep to get the proper platform-specific path segment separator.
const path = require('path');
// Path separators could change depending on the platform
const pathToCreate = 'path/to/dir';
pathToCreate
.split(path.sep)
.reduce((prevPath, folder) => {
const currentPath = path.join(prevPath, folder, path.sep);
if (!fs.existsSync(currentPath)){
fs.mkdirSync(currentPath);
}
return currentPath;
}, '');

As per the REST Implementation,
1) Path variables are used for the direct action on the resources, like a contact or a song
ex..
GET etc /api/resource/{songid} or
GET etc /api/resource/{contactid} will return respective data.
2) Query perms/argument are used for the in-direct resources like metadata of a song ex.., GET /api/resource/{songid}?metadata=genres it will return the genres data for that particular song.
Here's my code for 2D list in python which would read no. of rows from the input :
empty = []
row = int(input())
for i in range(row):
temp = list(map(int, input().split()))
empty.append(temp)
for i in empty:
for j in i:
print(j, end=' ')
print('')

As stated in the answer, in order to use a non deprecated way to sign your own script, one should use New-SelfSignedCertificate.
New-SelfSignedCertificate -DnsName [email protected] -Type CodeSigning -CertStoreLocation cert:\CurrentUser\My
Export-Certificate -Cert (Get-ChildItem Cert:\CurrentUser\My -CodeSigningCert)[0] -FilePath code_signing.crt
The [0] will make this work for cases when you have more than one certificate... Obviously make the index match the certificate you want to use... or use a way to filtrate (by thumprint or issuer).
Import-Certificate -FilePath .\code_signing.crt -Cert Cert:\CurrentUser\TrustedPublisher
Import-Certificate -FilePath .\code_signing.crt -Cert Cert:\CurrentUser\Root
Set-AuthenticodeSignature .\script.ps1 -Certificate (Get-ChildItem Cert:\CurrentUser\My -CodeSigningCert)
Obviously once you have setup the key, you can simply sign any other scripts with it.

When I ran into this error the fix was simple. I was simply missing a setter for a property. Make sure you define matching getters / setters for all your properties.
This is more general than .NET and Windows. Managed is an environment where you have automatic memory management, garbage collection, type safety, ... unmanaged is everything else. So for example .NET is a managed environment and C/C++ is unmanaged.

Throwing exceptions in a constructor is not bad practice. In fact, it is the only reasonable way for a constructor to indicate that there is a problem; e.g. that the parameters are invalid.
I also think that throwing checked exceptions can be OK1, assuming that the checked exception is 1) declared, 2) specific to the problem you are reporting, and 3) it is reasonable to expect the caller to deal with a checked exception for this2.
However explicitly declaring or throwing java.lang.Exception
is almost always bad practice.
You should pick an exception class that matches the exceptional condition that has occurred. If you throw Exception
it is difficult for the caller to separate this exception from any number of other possible declared and undeclared exceptions. This makes error recovery difficult, and if the caller chooses to propagate the Exception, the problem just spreads.
1 - Some people may disagree, but IMO there is no substantive difference between this case and the case of throwing exceptions in methods. The standard checked vs unchecked advice applies equally to both cases.
2 - For example, the existing FileInputStream
constructors will throw FileNotFoundException
if you try to open a file that does not exist. Assuming that it is reasonable for FileNotFoundException
to be a checked exception3, then the constructor is the most appropriate place for that exception to be thrown. If we threw the FileNotFoundException
the first time that (say) a read
or write
call was made, that is liable to make application logic more complicated.
3 - Given that this is one of the motivating examples for checked exceptions, if you don't accept this you are basically saying that all exceptions should be unchecked. That is not practical ... if you are going to use Java.
Someone suggested using assert
for checking arguments. The problem with this is that checking of assert
assertions can be turned on and off via a JVM command-line setting. Using assertions to check internal invariants is OK, but using them to implement argument checking that is specified in your javadoc is not a good idea ... because it means your method will only strictly implement the specification when assertion checking is enabled.
The second problem with assert
is that if an assertion fails, then AssertionError
will be thrown, and received wisdom is that it is a bad idea to attempt to catch Error
and any of its subtypes.
CoffeeScript version of this answer, with proper error handling:
fs = require "fs"
{join} = require "path"
async = require "async"
get_subdirs = (root, callback)->
fs.readdir root, (err, files)->
return callback err if err
subdirs = []
async.each files,
(file, callback)->
fs.stat join(root, file), (err, stats)->
return callback err if err
subdirs.push file if stats.isDirectory()
callback null
(err)->
return callback err if err
callback null, subdirs
Depends on async

.There is another useful method called AutoResizeColumn
which allows you to auto size a specific column with the required parameter.
You can call it like this:
listview1.AutoResizeColumn(1, ColumnHeaderAutoResizeStyle.ColumnContent);
listview1.AutoResizeColumn(2, ColumnHeaderAutoResizeStyle.ColumnContent);
listview1.AutoResizeColumn(3, ColumnHeaderAutoResizeStyle.HeaderSize);
listview1.AutoResizeColumn(4, ColumnHeaderAutoResizeStyle.HeaderSize);
like this :
df.groupby('colour').size().plot(kind='bar')
I write one with js and python, used in two projects, very nice and simple: a simple library (less then 2kb) used to format date with *** time ago
statement.
simple, small, easy used, and well tested.
npm install timeago.js
import timeago from 'timeago.js'; // or use script tag
use api format
.
Sample:
var timeagoIns = timeago();
timeagoIns .format('2016-06-12');
Also you can render in real-time.
var timeagoIns = timeago();
timeagoIns.render(document.querySelectorAll('time'));
You can use this method as an alternative.
What will happen is that we take all the tables associated with the users table and delete the related data using looping

foreach($tables as $table){
$table_name = $table->TABLE_NAME;
$column_name = $table->COLUMN_NAME;
DB::delete("delete from $table_name where $column_name = ?", [$id]);
}

As @ingyhere said:
Shallow Clone
First, turn off compression:
git config --global core.compression 0
Next, let's do a partial clone to truncate the amount of info coming down:
git clone --depth 1 <repo_URI>
When that works, go into the new directory and retrieve the rest of the clone:
git fetch --unshallow
or, alternately,
git fetch --depth=2147483647
Now, do a pull:
git pull --all
Then to solve the problem of your local branch only tracking master
open your git config file (.git/config
) in the editor of your choice
where it says:
[remote "origin"]
url=<git repo url>
fetch = +refs/heads/master:refs/remotes/origin/master
change the line
fetch = +refs/heads/master:refs/remotes/origin/master
to
fetch = +refs/heads/*:refs/remotes/origin/*
Do a git fetch and git will pull all your remote branches now
Using Boost.Filesystem:
boost::filesystem::path p("C:\\folder\\foo.txt");
boost::filesystem::path dir = p.parent_path();
The memory must be configured in several places.
Set memory_limit
to 512M:
sudo vi /etc/php5/cgi/php.ini
sudo vi /etc/php5/cli/php.ini
sudo vi /etc/php5/apache2/php.ini Or /etc/php5/fpm/php.ini
Restart service:
sudo service service php5-fpm restart
sudo service service nginx restart
or
sudo service apache2 restart
Finally it should solve the problem of the memory_limit

Here's a performance comparison of the two. HTTP is more responsive for request-response of small files, but FTP may be better for large files if tuned properly. FTP used to be generally considered faster. FTP requires a control channel and state be maintained besides the TCP state but HTTP does not. There are 6 packet transfers before data starts transferring in FTP but only 4 in HTTP.
I think a properly tuned TCP layer would have more effect on speed than the difference between application layer protocols. The Sun Blueprint Understanding Tuning TCP has details.
Heres another good comparison of individual characteristics of each protocol.
Everybody did explain why this problem occurs, but it's still very easy to forget about it and then scratching your head why you got wrong results. Especially when you're working on big sets of data when the results seem to be fine at first glance.
Using Object.entries
you ensure to go trough all properties:
var arr = [3, 5, 7];
arr.foo = "hello";
for ( var [key, val] of Object.entries( arr ) ) {
console.log( val );
}
/* Result:
3
5
7
hello
*/
new Date(new Date().setDate(new Date().getDate()-1))
var select = document.getElementById("DropList");
var length = select.options.length;
for (i = 0; i < length; i++) {
select.options[i].remove();
}

I ran into this exact problem too. In my case, adding parenthesis around any internal functions (to get them to evaluate first) seemed to do the trick:
Changed
=SUM(A1, SUBSTITUTE(A2,"x","3",1), A3)
to
=SUM(A1, (SUBSTITUTE(A2,"x","3",1)), A3)
It will merger two array and remove duplicate
<?php
$first = 'your first array';
$second = 'your second array';
$result = array_merge($first,$second);
print_r($result);
$result1= array_unique($result);
print_r($result1);
?>
Try this link link1
This is a way of doing the trick.
f = open("path_to_file", "r")
contents = f.readlines()
f.close()
contents.insert(index, value)
f = open("path_to_file", "w")
contents = "".join(contents)
f.write(contents)
f.close()
"index" and "value" are the line and value of your choice, lines starting from 0.
Just clear the scope model value on click event and it should do the trick for you.
<input type="text" ng-model="searchAll" />
<a class="clear" ng-click="searchAll = null">
<span class="glyphicon glyphicon-remove"></span>
</a>
Or if you keep your controller's $scope
function and clear it from there. Make sure you've set your controller correctly.
$scope.clearSearch = function() {
$scope.searchAll = null;
}
jww is right — you're referencing the wrong intermediate certificate.
As you have been issued with a SHA256 certificate, you will need the SHA256 intermediate. You can grab it from here: http://secure2.alphassl.com/cacert/gsalphasha2g2r1.crt
There is a very simple way to remove browser cache for http redirects e.g. 301, 307 etc.

Before pushing, do a git pull with rebase option. This will get the changes that you made online (in your origin) and apply them locally, then add your local changes on top of it.
git pull --rebase
Now, you can push to remote
git push

You can use "
If by version you mean a tag or a release, then github provides download links for those. For example, if I want to install fetch version 0.3.2 (it is not available on npm), then I add to my package.json
under dependencies
:
"fetch": "https://github.com/github/fetch/archive/v0.3.2.tar.gz",
The only disadvantage when compared with the commit hash approach is that a hash is guaranteed not to represent changed code, whereas a tag could be replaced. Thankfully this rarely happens.
Update:
These days the approach I use is the compact notation for a GitHub served dependency:
"dependencies": {
"package": "github:username/package#commit"
}
Where commit can be anything commitish, like a tag. In the case of GitHub you can even drop the initial github:
since it's the default.
I found part of the solution. Images now have metadata that specify the orientation of the photo. There is a new CSS spec for image-orientation
.
Just add this to your CSS:
img {
image-orientation: from-image;
}
According to the spec as of Jan 25 2016, Firefox and iOS Safari (behind a prefix) are the only browsers that support this. I'm seeing issues with Safari and Chrome still. However, mobile Safari seems to natively support orientation without the CSS tag.
I suppose we'll have to wait and see if browsers wills start supporting image-orientation
.
There is no real limit -- everything is named with a 160-bit name. The size of the file must be representable in a 64 bit number so no real limit there either.
There is a practical limit, though. I have a repository that's ~8GB with >880,000 files and git gc takes a while. The working tree is rather large so operations that inspect the entire working directory take quite a while. This repo is only used for data storage, though, so it's just a bunch of automated tools that handle it. Pulling changes from the repo is much, much faster than rsyncing the same data.

CREATE [TEMPORARY] TABLE [IF NOT EXISTS] tbl_name
[(create_definition,...)]
[table_options]
select_statement
Example :
CREATE TEMPORARY TABLE IF NOT EXISTS mytable
(id int(11) NOT NULL, PRIMARY KEY (id)) ENGINE=MyISAM;
INSERT IGNORE INTO mytable SELECT id FROM table WHERE xyz;
It's simple. Just do this:
#include <iostream>
#include <vector>
#include <string.h>
int main(int argc, char *argv[])
{
std::vector<std::string> argList;
for(int i=0;i<argc;i++)
argList.push_back(argv[i]);
//now you can access argList[n]
}
@Benjamin Lindley You are right. This is not a good solution. Please read the one answered by juanchopanza.
How about trying this?
public static void main (String [] args)
{
int [] [] listTwo = new int [5][5];
// 2 Dimensional array
int x = 0;
int y = 0;
while (x < 5) {
listTwo[x][y] = (int)(Math.random()*10);
while (y <5){
listTwo [x] [y] = (int)(Math.random()*10);
System.out.print(listTwo[x][y]+" | ");
y++;
}
System.out.println("");
y=0;
x++;
}
}
The basic setup of decorators is like this:
InputStream fileStream = new FileInputStream(filename);
InputStream gzipStream = new GZIPInputStream(fileStream);
Reader decoder = new InputStreamReader(gzipStream, encoding);
BufferedReader buffered = new BufferedReader(decoder);
The key issue in this snippet is the value of encoding
. This is the character encoding of the text in the file. Is it "US-ASCII", "UTF-8", "SHIFT-JIS", "ISO-8859-9", …? there are hundreds of possibilities, and the correct choice usually cannot be determined from the file itself. It must be specified through some out-of-band channel.
For example, maybe it's the platform default. In a networked environment, however, this is extremely fragile. The machine that wrote the file might sit in the neighboring cubicle, but have a different default file encoding.
Most network protocols use a header or other metadata to explicitly note the character encoding.
In this case, it appears from the file extension that the content is XML. XML includes the "encoding" attribute in the XML declaration for this purpose. Furthermore, XML should really be processed with an XML parser, not as text. Reading XML line-by-line seems like a fragile, special case.
Failing to explicitly specify the encoding is against the second commandment. Use the default encoding at your peril!
In Windows, with GetFileInformationByHandleEx, passing FileNameInfo, you can retrieve the file name.
To pipe the result to the response object (scenarios where there is a need to download the zip rather than store locally)
archive.pipe(res);
Sam's hints for accessing the content of the directory worked for me.
src: ["**/*"]
For C99 there is P99_DECLARE_ENUM
in P99 that lets you simply declare enum
like this:
P99_DECLARE_ENUM(color, red, green, blue);
and then use color_getname(A)
to obtain a string with the color name.
If you are using JetBrains editors like IntelliJ IDEA, PhpStorm, WebStorm etc. Use the following settings in Settings > File Watchers.
Convert style.scss
to style.css
set the arguments
--no-cache --update $FileName$:$FileNameWithoutExtension$.css
and output paths to refresh
$FileNameWithoutExtension$.css
Convert style.scss
to compressed style.min.css
set the arguments
--no-cache --update $FileName$:$FileNameWithoutExtension$.min.css --style compressed
and output paths to refresh
$FileNameWithoutExtension$.min.css
Thank you guys for the help,
When I asked at first I didn't think it's even possible, but after your answers I googled and found this amazing tutorial:
Are you looking for behavior similar to the x that shows up on the right side of text fields on an iphone that clears the text when tapped? It's called clearButtonMode there. Here is how to create that same functionality in an Android EditText view:
String value = "";//any text you are pre-filling in the EditText
final EditText et = new EditText(this);
et.setText(value);
final Drawable x = getResources().getDrawable(R.drawable.presence_offline);//your x image, this one from standard android images looks pretty good actually
x.setBounds(0, 0, x.getIntrinsicWidth(), x.getIntrinsicHeight());
et.setCompoundDrawables(null, null, value.equals("") ? null : x, null);
et.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (et.getCompoundDrawables()[2] == null) {
return false;
}
if (event.getAction() != MotionEvent.ACTION_UP) {
return false;
}
if (event.getX() > et.getWidth() - et.getPaddingRight() - x.getIntrinsicWidth()) {
et.setText("");
et.setCompoundDrawables(null, null, null, null);
}
return false;
}
});
et.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
et.setCompoundDrawables(null, null, et.getText().toString().equals("") ? null : x, null);
}
@Override
public void afterTextChanged(Editable arg0) {
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
});
If you mean lists, try ==
:
l1 = [1,2,3]
l2 = [1,2,3,4]
l1 == l2 # False
If you mean array
:
l1 = array('l', [1, 2, 3])
l2 = array('d', [1.0, 2.0, 3.0])
l1 == l2 # True
l2 = array('d', [1.0, 2.0, 3.0, 4.0])
l1 == l2 # False
If you want to compare strings (per your comment):
date_string = u'Thu Sep 16 13:14:15 CDT 2010'
date_string2 = u'Thu Sep 16 14:14:15 CDT 2010'
date_string == date_string2 # False
Another instance that I faced while trying to use the camera, was that it was still busy crashing giving same _CRASHING_DUE_TO_PRIVACY
even after adding the "Camera Usage Description". After failing to get anything tangible from the call stack, switched to the "Organizer" and looked into the crash reports on the device. I found that it was in fact complaining about the privacy due to the missing "Microphone Usage Description". I added that and got rid of such a cryptic break down.
No other "addClass" methods worked for me when adding a class to an 'a' element on menu except this one:
$(function () {
var url = window.location.pathname,
urlRegExp = new RegExp(url.replace(/\/$/, '') + "$");
$('a').each(function () {
if (urlRegExp.test(this.href.replace(/\/$/, ''))) {
$(this).addClass('active');
}
});
});
This took me four hours to find it.
I go with Mark Longair's solution and comments and recommend anyone reads those before acting, but I'd suggest the emphasis should be on
git branch -f <branchname> <commit>
Here is a scenario where I have needed to do this.
Develop on the wrong branch and hence need to reset it.
Cleanly develop and release some software.
Mistake: Accidentally stay on the release branch while developing further.
"OH NO! I accidentally developed on the release branch." The workspace is maybe cluttered with half changed files that represent work-in-progress and we really don't want to touch and mess with. We'd just like git to flip a few pointers to keep track of the current state and put that release branch back how it should be.
Create a branch for the development that is up to date holding the work committed so far and switch to it.
git branch development
git checkout development
Now we are in the problem situation and need its solution! Rectify the mistake (of taking the release branch forward with the development) and put the release branch back how it should be.
Correct the release branch to point back to the last real release.
git branch -f release release2
The release branch is now correct again, like this ...
git push -f <remote> <branch>
is well described in another thread, though the word "overwrite" in the title is misleading.
Force "git push" to overwrite remote files
Best practice is to use an interface to specify the contract and an abstract class as just one implementation thereof. That abstract class can fill in a lot of the boilerplate so you can create an implementation by just overriding what you need to or want to without forcing you to use a particular implementation.
Or for what seems like rampant overkill, but is actually simplistic ... Pretty much covers all of your cases, and no empty string or unary concerns.
In the case the first arg is '-v', then do your conditional ps -ef
, else in all other cases throw the usage.
#!/bin/sh
case $1 in
'-v') if [ "$1" = -v ]; then
echo "`ps -ef | grep -v '\['`"
else
echo "`ps -ef | grep '\[' | grep root`"
fi;;
*) echo "usage: $0 [-v]"
exit 1;; #It is good practice to throw a code, hence allowing $? check
esac
If one cares not where the '-v' arg is, then simply drop the case inside a loop. The would allow walking all the args and finding '-v' anywhere (provided it exists). This means command line argument order is not important. Be forewarned, as presented, the variable arg_match is set, thus it is merely a flag. It allows for multiple occurrences of the '-v' arg. One could ignore all other occurrences of '-v' easy enough.
#!/bin/sh
usage ()
{
echo "usage: $0 [-v]"
exit 1
}
unset arg_match
for arg in $*
do
case $arg in
'-v') if [ "$arg" = -v ]; then
echo "`ps -ef | grep -v '\['`"
else
echo "`ps -ef | grep '\[' | grep root`"
fi
arg_match=1;; # this is set, but could increment.
*) ;;
esac
done
if [ ! $arg_match ]
then
usage
fi
But, allow multiple occurrences of an argument is convenient to use in situations such as:
$ adduser -u:sam -s -f -u:bob -trace -verbose
We care not about the order of the arguments, and even allow multiple -u arguments. Yes, it is a simple matter to also allow:
$ adduser -u sam -s -f -u bob -trace -verbose
I'll try to explain it visually:

non of the solutions worked well for me. especially when there are many gaps and set is small. this worked very well for me(in php):
$count = $collection->count($search);
$skip = mt_rand(0, $count - 1);
$result = $collection->find($search)->skip($skip)->limit(1)->getNext();
Since I had this problem following an upgrade, I just disable Apache2-php5
a2dismod php5
and activated php7
a2enmod php7
Hope it may help anybody!
You can use MATCH
for instance.
Select the column from the first cell, for example cell A2 to cell A100 and insert a conditional formatting, using 'New Rule...' and the option to conditional format based on a formula.
In the entry box, put:
=MATCH(A2, 'Sheet2'!A:A, 0)
Pick the desired formatting (change the font to red or fill the cell background, etc) and click OK.
MATCH
takes the value A2
from your data table, looks into 'Sheet2'!A:A
and if there's an exact match (that's why there's a 0
at the end), then it'll return the row number.
Note: Conditional formatting based on conditions from other sheets is available only on Excel 2010 onwards. If you're working on an earlier version, you might want to get the list of 'Don't check' in the same sheet.
EDIT: As per new information, you will have to use some reverse matching. Instead of the above formula, try:
=SUM(IFERROR(SEARCH('Sheet2'!$A$1:$A$44, A2),0))
and the fully automated way with bash and expect ( in this example we provision a new postgres admin with the newly provisioned postgres pw both on OS and postgres run-time level )

# for reference the manual way of doing things automated with expect bellow

Faced this issue recently with TypeScript 1.0.1, and solved this way:
enum IEvents {
/** A click on a product or product link for one or more products. */
CLICK,
/** A view of product details. */
DETAIL,
/** Adding one or more products to a shopping cart. */
ADD,
/** Remove one or more products from a shopping cart. */
REMOVE,
/** Initiating the checkout process for one or more products. */
CHECKOUT,
/** Sending the option value for a given checkout step. */
CHECKOUT_OPTION,
/** The sale of one or more products. */
PURCHASE,
/** The refund of one or more products. */
REFUND,
/** A click on an internal promotion. */
PROMO_CLICK
}
var Events = [
'click',
'detail',
'add',
'remove',
'checkout',
'checkout_option',
'purchase',
'refund',
'promo_click'
];
function stuff(event: IEvents):boolean {
// event can now be only IEvents constants
Events[event]; // event is actually a number that matches the index of the array
}
// stuff('click') won't work, it needs to be called using stuff(IEvents.CLICK)
ffmpeg -i sample.avi
will give you the audio/video format info for your file. Make sure you have the proper libraries configured to parse the input streams. Also, make sure that the file isn't corrupt.
I had same issue. I have tried many things but nothing worked Until I try following:
gradle-[version]-all
within C:\Users\<username>\.gradle\wrapper\dists\
. If you encounter a "File in use" error (or similar), terminate any running Java executables..gradle
directory.I guess something like this would work:
Add System.ServiceProcess
to your project references (It's on the .NET tab).
using System.ServiceProcess;
ServiceController sc = new ServiceController(SERVICENAME);
switch (sc.Status)
{
case ServiceControllerStatus.Running:
return "Running";
case ServiceControllerStatus.Stopped:
return "Stopped";
case ServiceControllerStatus.Paused:
return "Paused";
case ServiceControllerStatus.StopPending:
return "Stopping";
case ServiceControllerStatus.StartPending:
return "Starting";
default:
return "Status Changing";
}
Edit: There is also a method sc.WaitforStatus()
that takes a desired status and a timeout, never used it but it may suit your needs.
Edit: Once you get the status, to get the status again you will need to call sc.Refresh()
first.
Reference: ServiceController object in .NET.
When you do echo $array;
, PHP will simply echo 'Array' since it can't convert an array to a string. So The 'A' that you are actually getting is the first letter of Array, which is correct.
You might actually need
echo json_encode($array);
This should get you what you want.
EDIT : And obviously, you'd need to change your JS to work with JSON instead of just text (as pointed out by @genesis)
[attr.disabled]="valid == true ? true : null"
You have to use null
to remove attr from html element.
You can use tabindex="-1"
.
The W3C HTML5 specification supports negative tabindex
values:
If the value is a negative integer
The user agent must set the element's tabindex focus flag, but should not allow the element to be reached using sequential focus navigation.
Watch out though that this is a HTML5 feature and might not work with old browsers.
To be W3C HTML 4.01 standard (from 1999) compliant, tabindex would need to be positive.
Sample usage below in pure HTML.
<input />_x000D_
<input tabindex="-1" placeholder="NoTabIndex" />_x000D_
<input />
_x000D_
<span>
will allow you to style text, but it adds no semantic content.
As you're emphasizing some text, it sounds like you'd be better served by wrapping the text in <em></em>
and using CSS to change the color of the <em>
element. For example:
.description {
color: #fff;
}
.description em {
color: #ffa500;
}
<p class="description">Lorem ipsum dolor sit amet, consectetur
adipiscing elit. Sed hendrerit mollis varius. Etiam ornare placerat
massa, <em>eget vulputate tellus fermentum.</em></p>
In fact, I'd go to great pains to avoid the <span>
element, as it's completely meaningless to everything that doesn't render your style sheet (bots, screen readers, luddites who disable styles, parsers, etc.) or renders it in unexpected ways (personal style sheets). In many ways, it's no better than using the <font>
element.
.description {_x000D_
color: #000;_x000D_
}_x000D_
_x000D_
.description em {_x000D_
color: #ffa500;_x000D_
}
_x000D_
<p class="description">Lorem ipsum dolor sit amet, consectetur _x000D_

There is only workaround for the issue you are facing.
Check whether file id in process before starting the process of copy. You can call the following function until you get the False value.
1st Method, copied directly from this answer:
private bool IsFileLocked(FileInfo file)
{
FileStream stream = null;
try
{
stream = file.Open(FileMode.Open, FileAccess.ReadWrite, FileShare.None);
}
catch (IOException)
{
//the file is unavailable because it is:
//still being written to
//or being processed by another thread
//or does not exist (has already been processed)
return true;
}
finally
{
if (stream != null)
stream.Close();
}
//file is not locked
return false;
}
2nd Method:
const int ERROR_SHARING_VIOLATION = 32;
const int ERROR_LOCK_VIOLATION = 33;
private bool IsFileLocked(string file)
{
//check that problem is not in destination file
if (File.Exists(file) == true)
{
FileStream stream = null;
try
{
stream = File.Open(file, FileMode.Open, FileAccess.ReadWrite, FileShare.None);
}
catch (Exception ex2)
{
//_log.WriteLog(ex2, "Error in checking whether file is locked " + file);
int errorCode = Marshal.GetHRForException(ex2) & ((1 << 16) - 1);
if ((ex2 is IOException) && (errorCode == ERROR_SHARING_VIOLATION || errorCode == ERROR_LOCK_VIOLATION))
{
return true;
}
}
finally
{
if (stream != null)
stream.Close();
}
}
return false;
}
VSCode comes with in-built color themes which can be used to change the colors of the editor and the terminal.
ctrl+k+t
in windows/ubuntu or cmd+k+t
on mac.ctrl+shift+p
in windows/ubuntu or cmd+shift+p
on mac and type color
. Select preferences: color theme
from the options, to select your favourite color.category:themes
to install your favourite themes. (If you need to sort the themes by installs search category:themes @sort:installs
)Edit - for manually editing colors in terminal
VSCode team have removed customizing colors from user settings page. Currently using the themes is the only way to customize terminal colors in VSCode. For more information check out issue #6766
You can open the preferences (multiple options):

And depending on the Spyder version you can change the interpreter in the Python interpreter
section (Spyder 3.x):
or in the advanced Console
section (Spyder 2.x):
You don't need to create the table first and then add the keys in subsequent steps. You can add both primary key and foreign key while creating the table:
This example assumes the existence of a table (Codes
) that we would want to reference with our foreign key.
CREATE TABLE d (
id [numeric](1),
code [varchar](2),
PRIMARY KEY (id, code),
CONSTRAINT fk_d_codes FOREIGN KEY (code) REFERENCES Codes (code)
)
If you don't have a table that we can reference, add one like this so that the example will work:
CREATE TABLE Codes (
Code [varchar](2) PRIMARY KEY
)
NOTE: you must have a table to reference before creating the foreign key.
The toString()
implementation of java.util.Date
does not depend on the way the class is imported. It always returns a nice formatted date.
The toString()
you see comes from another class.
Specific import have precedence over wildcard imports.
in this case
import other.Date
import java.util.*
new Date();
refers to other.Date
and not java.util.Date
.
The odd thing is that
import other.*
import java.util.*
Should give you a compiler error stating that the reference to Date is ambiguous because both other.Date
and java.util.Date
matches.
you can use pathlib
from pathlib import Path
Path(r"C:\folder1\folder2\filename.xml").parts[-2]
The output of the above was this:
'folder2'
Here's a pretty ggplot2 solution:
library(ggplot2)
library(scales) # makes pretty labels on the x-axis
breaks=c(0,1,2,3,4,5,25)
ggplot(mydata,aes(x = V3)) +
geom_histogram(breaks = log10(breaks)) +
scale_x_log10(
breaks = breaks,
labels = scales::trans_format("log10", scales::math_format(10^.x))
)
Note that to set the breaks in geom_histogram, they had to be transformed to work with scale_x_log10
Row(
children: <Widget>[
Flexible(
child: TextFormField()),
Container(width: 20, height: 20),
Flexible(
child: TextFormField())
])
This works for me, there are 3 widgets inside row: Flexible, Container, Flexible
Starting with AspNetCore 2.0, it's recommended to use ContentResult
instead of the Produce
attribute in this case. See: https://github.com/aspnet/Mvc/issues/6657#issuecomment-322586885
This doesn't rely on serialization nor on content negotiation.
[HttpGet]
public ContentResult Index() {
return new ContentResult {
ContentType = "text/html",
StatusCode = (int)HttpStatusCode.OK,
Content = "<html><body>Hello World</body></html>"
};
}
I'm not sure about the "@" used in the selector. At least with the latest jQuery, I had to remove the @ to get this to function with two different checkbox arrays, otherwise all checked items were selected for each array:
var items = [];
$("input[name='items[]']:checked").each(function(){items.push($(this).val());});
var about = [];
$("input[name='about[]']:checked").each(function(){about.push($(this).val());});
Now both, items and about work.
Actually you don't have to create an image at all. drawImage()
will accept a Canvas
as well as an Image
object.
//grab the context from your destination canvas
var destCtx = destinationCanvas.getContext('2d');
//call its drawImage() function passing it the source canvas directly
destCtx.drawImage(sourceCanvas, 0, 0);
Way faster than using an ImageData
object or Image
element.
Note that sourceCanvas
can be a HTMLImageElement, HTMLVideoElement, or a HTMLCanvasElement. As mentioned by Dave in a comment below this answer, you cannot use a canvas drawing context as your source. If you have a canvas drawing context instead of the canvas element it was created from, there is a reference to the original canvas element on the context under context.canvas
.
Here is a jsPerf to demonstrate why this is the only right way to clone a canvas: http://jsperf.com/copying-a-canvas-element
Besides the powerful options on the "Run Configurations.." on a well configured project you'll see the maven tasks on the Run As as well.
Use Counter
>>> from collections import Counter
>>> MyList = ["a", "b", "a", "c", "c", "a", "c"]
>>> c = Counter(MyList)
>>> c
Counter({'a': 3, 'c': 3, 'b': 1})
When changing fonts in XCode from [Preferences] (after duplicating a template that matches colours close to what you want), you can select multiple entries and change the fonts all at once. Use [shift] to select a range or [cmd] to select multiple individual entries (e.g. you might select both 'comments' and 'strings' and change only their fonts).

Better solution with smooth animation:
// this changes the scrolling behavior to "smooth"
window.scrollTo({ top: 0, behavior: 'smooth' });

Not different for other answers, my framework have almost the same levels:
You'll need to add the other repository as a remote, then fetch its changes. From there you see the commit and you can cherry-pick it.
Like that:
git remote add other https://example.link/repository.git
git fetch other
Now you have all the information to simply do git cherry-pick
.
More info about working with remotes here: https://git-scm.com/book/en/v2/Git-Basics-Working-with-Remotes
Include js files of datepicker and language (locales)
'resource/bower_components/bootstrap-datepicker/dist/js/bootstrap-datepicker.min.js',
'resource/bower_components/bootstrap-datepicker/dist/locales/bootstrap-datepicker.sv.min.js',
In the options of the datepicker, set the language as below:
$('.datepicker').datepicker({'language' : 'sv'});
I +1'd Miro's answer for the link to the header-checker site http://www.webconfs.com/http-header-check.php. It pops up an obnoxious ad every time you use it, but it is, nevertheless, very useful for verifying the presence of the Access-Control-Allow-Origin header.
I'm reading a .json file from the javascript on my web page. I found that adding the following to my .htaccess file fixed the problem when viewing my web page in IE 11 (version 11.447.14393.0):
<FilesMatch "\.(json)$">
<IfModule mod_headers.c>
Header set Access-Control-Allow-Origin "*"
</IfModule>
</FilesMatch>
I also added the following to /etc/httpd.conf (Apache's configuration file):
AllowOverride All
The header-checker site verified that the Access-Control-Allow-Origin header is now being sent (thanks, Miro!).
However, Firefox 50.0.2, Opera 41.0.2353.69, and Edge 38.14393.0.0 all fetch the file anyhow, even without the Access-Control-Allow-Origin header. (Note: they might be checking IP addresses, since the two domains I was using are both hosted on the same server, at the same IPv4 address.)
However, Chrome 54.0.2840.99 m (64-bit) ignores the Access-Control-Allow-Origin header and fails anyhow, erroneously reporting:
No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin '{mydomain}' is therefore not allowed access.
I think this has got to be some sort of "first." IE is working correctly; Chrome, Firefox, Opera and Edge are all buggy; and Chrome is the worst. Isn't that the exact opposite of the usual case?
Its not that hard to replicate in javascript :-) , though it will only work for width and height the best but you can expand it as per your expectations :-)
function calcShim(element,property,expression){
var calculated = 0;
var freed_expression = expression.replace(/ /gi,'').replace("(","").replace(")","");
// Remove all the ( ) and spaces
// Now find the parts
var parts = freed_expression.split(/[\*+-\/]/gi);
var units = {
'px':function(quantity){
var part = 0;
part = parseFloat(quantity,10);
return part;
},
'%':function(quantity){
var part = 0,
parentQuantity = parseFloat(element.parent().css(property));
part = parentQuantity * ((parseFloat(quantity,10))/100);
return part;
} // you can always add more units here.
}
for( var i = 0; i < parts.length; i++ ){
for( var unit in units ){
if( parts[i].indexOf(unit) != -1 ){
// replace the expression by calculated part.
expression = expression.replace(parts[i],units[unit](parts[i]));
break;
}
}
}
// And now compute it. though eval is evil but in some cases its a good friend.
// Though i wish there was math. calc
element.css(property,eval(expression));
}
Current best practice in CSS development is to create more general selectors with modifiers that can be applied as widely as possible throughout the web site. I would try to avoid defining separate styles for individual page elements.
If the purpose of the CSS class on the <form/>
element is to control the style of elements within the form, you could add the class attribute the existing <fieldset/>
element which encapsulates any form by default in web pages generated by ASP.NET MVC. A CSS class on the form is rarely necessary.

A hack the I've used on Solaris 9 and Linux and which works fine for both of them:
ps -o user= -p $$ | awk '{print $1}'
This snippet prints the name of the user with the current EUID.
NOTE: you need Bash as the interpreter here.
On Solaris you have problems with methods, described above:
id
does not accept the -u
and -n
parameters (so you will have to parse the output)whoami
does not exist (by default)who am I
prints owner of current terminal (ignores EUID)$USER
variable is set correctly only after reading profile files (for example, /etc/profile
)Alright guys, I found it out! I didn't really need to change the java.library.path but the "Native library location" of sqljdbc.jar

Simply create @IBDesignable
subclass of your UITextView
:
@IBDesignable class AttributedTextView: UITextView {
private let placeholderLabel = UILabel()
@IBInspectable var placeholder: String = "" {
didSet {
setupPlaceholderLabelIfNeeded()
textViewDidChange()
}
}
override var text: String! {
didSet {
textViewDidChange()
}
}
//MARK: - Initialization
override func awakeFromNib() {
super.awakeFromNib()
setupPlaceholderLabelIfNeeded()
NotificationCenter.default.addObserver(self, selector: #selector(textViewDidChange), name: .UITextViewTextDidChange, object: nil)
}
//MARK: - Deinitialization
deinit {
NotificationCenter.default.removeObserver(self)
}
//MARK: - Internal
func textViewDidChange() {
placeholderLabel.isHidden = !text.isEmpty
layoutIfNeeded()
}
//MARK: - Private
private func setupPlaceholderLabelIfNeeded() {
placeholderLabel.removeFromSuperview()
placeholderLabel.frame = CGRect(x: 0, y: 8, width: frame.size.width, height: 0)
placeholderLabel.textColor = UIColor.lightGray
placeholderLabel.text = placeholder
placeholderLabel.sizeToFit()
insertSubview(placeholderLabel, at: 0)
}
}
and then simply setup your placeholder in identity inspector:
There are really two separate issues. The first is keeping the elements of the array in proper order so that there are no "holes" after removing an element. The second is actually resizing the array itself.
Arrays in C are allocated as a fixed number of contiguous elements. There is no way to actually remove the memory used by an individual element in the array but the elements can be shifted to fill the hole made by removing an element. For example:
void remove_element(array_type *array, int index, int array_length)
{
int i;
for(i = index; i < array_length - 1; i++) array[i] = array[i + 1];
}
Statically allocated arrays can not be resized. Dynamically allocated arrays can be resized with realloc(). This will potentially move the entire array to another location in memory, so all pointers to the array or to its elements will have to be updated. For example:
remove_element(array, index, array_length); /* First shift the elements, then reallocate */
array_type *tmp = realloc(array, (array_length - 1) * sizeof(array_type) );
if (tmp == NULL && array_length > 1) {
/* No memory available */
exit(EXIT_FAILURE);
}
array_length = array_length - 1;
array = tmp;
realloc will return a NULL pointer if the requested size is 0, or if there is an error. Otherwise it returns a pointer to the reallocated array. The temporary pointer is used to detect errors when calling realloc because instead of exiting it is also possible to just leave the original array as it was. When realloc fails to reallocate an array it does not alter the original array.
Note that both of these operations will be fairly slow if the array is large or if a lot of elements are removed. There are other data structures like linked lists and hashes that can be used if efficient insertion and deletion is a priority.
For me both of these below worked, make sure your Domain is given with LDAP:// in start

Since C# 8.0 introduced a new switch expression for enums you can do it even more elegant:
public double Calculate(int left, int right, Operator op) =>
op switch
{
Operator.PLUS => left + right,
Operator.MINUS => left - right,
Operator.MULTIPLY => left * right,
Operator.DIVIDE => left / right,
_ => 0
}

Do simply like below....
HashMap<String,Object> yourHash = new HashMap<String,Object>();
yourHash.put(yourKey+"message","message");
yourHash.put(yourKey+"timestamp",timestamp);
yourHash.put(yourKey+"count ",count);
yourHash.put(yourKey+"version ",version);
typecast the value while getting back. For ex:
int count = Integer.parseInt(yourHash.get(yourKey+"count"));
//or
int count = Integer.valueOf(yourHash.get(yourKey+"count"));
//or
int count = (Integer)yourHash.get(yourKey+"count"); //or (int)
On linux I cannot set lower_case_table_names
to 2
(it reverts to 0
), but I can set it to 1
.
Before changing this setting, do a complete dump of all databases, and drop all databases. You won't be able to drop them after setting lower_case_table_names
to 1
, because any uppercase characters in database or table names will prevent them from being referenced.
Then set lower_case_table_names
to 1
, restart MySQL, and re-load your data, which will convert everything to lowercase, including any subsequent queries made.
