The simplest and most effective way to make a file available to your component is this:
var data = require('json!./data.json');
Note the json!
before the path
For me the problem was my file encoding...I used powershell to write the xml file and this was not UTF-8 ... It seems that spring requires UTF8 because as soon as I changed the encoding (using notepad++) it works again without any errors
Now i Use in my powershellscript the following line to output the xml file in UTF-8: [IO.File]::WriteAllLines($fname_dataloader_xml_config_file, $dataloader_configfile)
instead of using the redirection operator > to create my file
Note: I didn't put any xml parameters in my beans tag and it works

To retrieve the current directory you can use the dynamic %cd%
variable that holds the current active directory
set "curpath=%cd%"
This generates a value with a ending backslash for the root directory, and without a backslash for the rest of directories. You can force and ending backslash for any directory with
for %%a in ("%cd%\") do set "curpath=%%~fa"
Or you can use another dynamic variable: %__CD__%
that will return the current active directory with an ending backslash.
Also, remember the %cd%
variable can have a value directly assigned. In this case, the value returned will not be the current directory, but the assigned value. You can prevent this with a reference to the current directory
for %%a in (".\") do set "curpath=%%~fa"
Up to windows XP, the %__CD__%
variable has the same behaviour. It can be overwritten by the user, but at least from windows 7 (i can't test it on Vista), any change to the %__CD__%
is allowed but when the variable is read, the changed value is ignored and the correct current active directory is retrieved (note: the changed value is still visible using the set
command).
BUT all the previous codes will return the current active directory, not the directory where the batch file is stored.
set "curpath=%~dp0"
It will return the directory where the batch file is stored, with an ending backslash.
BUT this will fail if in the batch file the shift
command has been used
shift
echo %~dp0
As the arguments to the batch file has been shifted, the %0
reference to the current batch file is lost.
To prevent this, you can retrieve the reference to the batch file before any shifting, or change the syntax to shift /1
to ensure the shift operation will start at the first argument, not affecting the reference to the batch file. If you can not use any of this options, you can retrieve the reference to the current batch file in a call to a subroutine
@echo off
setlocal enableextensions
rem Destroy batch file reference
shift
echo batch folder is "%~dp0"
rem Call the subroutine to get the batch folder
call :getBatchFolder batchFolder
echo batch folder is "%batchFolder%"
exit /b
:getBatchFolder returnVar
set "%~1=%~dp0" & exit /b
This approach can also be necessary if when invoked the batch file name is quoted and a full reference is not used (read here).
We can copy all columns from one table to another, existing table:
INSERT INTO table2 SELECT * FROM table1;
Or we can copy only the columns we want to into another, existing table:
INSERT INTO table2 (column_name(s)) SELECT column_name(s) FROM table1;
or SELECT * INTO BACKUP_TABLE1 FROM TABLE1
If you i would like move scroll animation in the table, use this code. The scroll move to top with animation in .5 seconds.
[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:0.5];
[UIView setAnimationCurve:UIViewAnimationCurveEaseOut];
[_tableContent scrollRectToVisible:CGRectMake(0, 0, 1, 1) animated:YES];
[UIView commitAnimations];
Yo can simply google for "exit sub in c#".
Also why would you check every text box if it is empty. You can place requiredfieldvalidator for these text boxes if this is an asp.net app and check if(Page.IsValid)
Or another solution is to get not of these conditions:
private void button1_Click(object sender, EventArgs e)
{
if (!(textBox1.Text == "" || textBox2.Text == "" || textBox3.Text == ""))
{
//do events
}
}
And better use String.IsNullOrEmpty:
private void button1_Click(object sender, EventArgs e)
{
if (!(String.IsNullOrEmpty(textBox1.Text)
|| String.IsNullOrEmpty(textBox2.Text)
|| String.IsNullOrEmpty(textBox3.Text)))
{
//do events
}
}
Simple answer:
$("#listItem").contents().filter(function(){
return this.nodeType == 3;
})[0].nodeValue = "The text you want to replace with"
I've just started listening to the irreverent Sod This podcast series, hosted by Gary Short and Oliver Sturm of DevExpress. They are fairly entertaining and mildly educational with a guest slot, slightly sweary though.
For those who want to round up a / b
and get integer:
Another variant using integer division is
def int_ceil(a, b):
return (a - 1) // b + 1
>>> int_ceil(19, 5)
4
>>> int_ceil(20, 5)
4
>>> int_ceil(21, 5)

In xamarin if you face this issue when you add any new sdk. The simple solution is Open your styles file and add this line.
<style name="AppTheme" parent="android:Theme.Holo.Light.DarkActionBar"></style>
It's better solution rather than adding appcompat.
using ssh from java should not be as hard as jsch makes it. you might be better off with sshj.
I recommend you take a look at the list of editors on Python's wiki, as well as these related questions:
On windows if you just did a clean install and you get this you need blow away your npm cache in \AppData\Roaming
I know this is a repeat of other answers, but it has some emotional support to take the extra step for testing update :D
For testing update, hash # is your friend.
If you have an update statement like:
UPDATE
wp_history
SET history_by="admin"
WHERE
history_ip LIKE '123%'
You hash UPDATE and SET out for testing, then hash them back in:
SELECT * FROM
#UPDATE
wp_history
#SET history_by="admin"
WHERE
history_ip LIKE '123%'
It works for simple statements.
An additional practically mandatory solution is, to get a copy (backup duplicate), whenever using update on a production table. Phpmyadmin > operations > copy: table_yearmonthday. It just takes a few seconds for tables <=100M.
After the long time research i have found the solution for above:
Firstly you change the wp-config.php> Database DB_CHARSET default to "utf8"
Click the "Export" tab for the database
Click the "Custom" radio button
Go the section titled "Format-specific options" and change the dropdown for "Database system or older MySQL server to maximize output compatibility with:" from NONE to MYSQL40.
Scroll to the bottom and click go
Then you are on.
You may use:
if ( frm.product.value=="F" ){
var $select_box = $('[name=val]');
$select_box.find('[value=A],[value=C]').remove();
}
Update: If you modify your select box a bit to this
<select name="val" size="1" >
<option id="A" value="A">Apple</option>
<option id="C" value="C">Cars</option>
<option id="H" value="H">Honda</option>
<option id="F" value="F">Fiat</option>
<option id="I" value="I">Indigo</option>
</select>
the non-jQuery solution would be this
if ( frm.product.value=="F" ){
var elem = document.getElementById('A');
elem.parentNode.removeChild(elem);
var elem = document.getElementById('C');
elem.parentNode.removeChild(elem);
}
Try passing columns of the DataFrame
directly to matplotlib, as in the examples below, instead of extracting them as numpy arrays.
df = pd.DataFrame(np.random.randn(10,2), columns=['col1','col2'])
df['col3'] = np.arange(len(df))**2 * 100 + 100
In [5]: df
Out[5]:
col1 col2 col3
0 -1.000075 -0.759910 100
1 0.510382 0.972615 200
2 1.872067 -0.731010 500
3 0.131612 1.075142 1000
4 1.497820 0.237024 1700
plt.scatter(df.col1, df.col2, s=df.col3)
# OR (with pandas 0.13 and up)
df.plot(kind='scatter', x='col1', y='col2', s=df.col3)
colors = np.where(df.col3 > 300, 'r', 'k')
plt.scatter(df.col1, df.col2, s=120, c=colors)
# OR (with pandas 0.13 and up)
df.plot(kind='scatter', x='col1', y='col2', s=120, c=colors)
However, the easiest way I've found to create a scatter plot with legend is to call plt.scatter
once for each point type.
cond = df.col3 > 300
subset_a = df[cond].dropna()
subset_b = df[~cond].dropna()
plt.scatter(subset_a.col1, subset_a.col2, s=120, c='b', label='col3 > 300')
plt.scatter(subset_b.col1, subset_b.col2, s=60, c='r', label='col3 <= 300')
plt.legend()
From what I can tell, matplotlib simply skips points with NA x/y coordinates or NA style settings (e.g., color/size). To find points skipped due to NA, try the isnull
method: df[df.col3.isnull()]
To split a list of points into many types, take a look at numpy select
, which is a vectorized if-then-else implementation and accepts an optional default value. For example:
df['subset'] = np.select([df.col3 < 150, df.col3 < 400, df.col3 < 600],
[0, 1, 2], -1)
for color, label in zip('bgrm', [0, 1, 2, -1]):
subset = df[df.subset == label]
plt.scatter(subset.col1, subset.col2, s=120, c=color, label=str(label))
plt.legend()
I was receiving the same error message, and my issue was that I was not in the correct directory when running the command make install
. When I changed to the directory that had my makefile it worked.
So possibly you aren't in the right directory.
The .spec.ts files are for unit tests for individual components.
You can run Karma task runner through ng test
. In order to see code coverage of unit test cases for particular components run ng test --code-coverage
Often when you need to show so many points on the map, you'd be better off using the server-side approach, this article explains when to use each:
Geocoding Strategies: https://developers.google.com/maps/articles/geocodestrat
The client-side limit is not exactly "10 requests per second", and since it's not explained in the API docs I wouldn't rely on its behavior.
You can use the return value of the function to prevent the form submission
<form name="myForm" onsubmit="return validateMyForm();">
and function like
<script type="text/javascript">
function validateMyForm()
{
if(check if your conditions are not satisfying)
{
alert("validation failed false");
returnToPreviousPage();
return false;
}
alert("validations passed");
return true;
}
</script>
In case of Chrome 27.0.1453.116 m if above code does not work, please set the event handler's parameter's returnValue field to false to get it to work.
Thanks Sam for sharing information.
EDIT :
Thanks to Vikram for his workaround for if validateMyForm() returns false:
<form onsubmit="event.preventDefault(); validateMyForm();">
where validateMyForm() is a function that returns false if validation fails. The key point is to use the name event. We cannot use for e.g. e.preventDefault()
No need to be complex. The simplest and framework manner is to use ACCESS_NETWORK_STATE
permission and just make a connected method
public boolean isOnline() {
ConnectivityManager cm =
(ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
return cm.getActiveNetworkInfo() != null &&
cm.getActiveNetworkInfo().isConnectedOrConnecting();
}
You can also use requestRouteToHost
if you have a particualr host and connection type (wifi/mobile) in mind.
You will also need:
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
in your android manifest.
Rethrowing exceptions via throw
is useful when you don't have a particular code to handle current exceptions, or in cases when you have a logic to handle specific error cases but want to skip all others.
Example:
string numberText = "";
try
{
Console.Write("Enter an integer: ");
numberText = Console.ReadLine();
var result = int.Parse(numberText);
Console.WriteLine("You entered {0}", result);
}
catch (FormatException)
{
if (numberText.ToLowerInvariant() == "nothing")
{
Console.WriteLine("Please, please don't be lazy and enter a valid number next time.");
}
else
{
throw;
}
}
finally
{
Console.WriteLine("Freed some resources.");
}
Console.ReadKey();
However, there is also another way of doing this, using conditional clauses in catch blocks:
string numberText = "";
try
{
Console.Write("Enter an integer: ");
numberText = Console.ReadLine();
var result = int.Parse(numberText);
Console.WriteLine("You entered {0}", result);
}
catch (FormatException) when (numberText.ToLowerInvariant() == "nothing")
{
Console.WriteLine("Please, please don't be lazy and enter a valid number next time.");
}
finally
{
Console.WriteLine("Freed some resources.");
}
Console.ReadKey();
This mechanism is more efficient than re-throwing an exception because of the .NET runtime doesn’t have to rebuild the exception object before re-throwing it.
I know I'm am very late on this, but here some usefull samples:
'select the used cells in column 3 of worksheet wks
wks.columns(3).SpecialCells(xlCellTypeConstants).Select
or
'change all formulas in col 3 to values
with sheet1.columns(3).SpecialCells(xlCellTypeFormulas)
.value = .value
end with
To find the last used row in column, never rely on LastCell, which is unreliable (it is not reset after deleting data). Instead, I use someting like
lngLast = cells(rows.count,3).end(xlUp).row
For Kotlin users, I created a ImageStorageManager
class which will handle save, get and delete actions for images easily:
class ImageStorageManager {
companion object {
fun saveToInternalStorage(context: Context, bitmapImage: Bitmap, imageFileName: String): String {
context.openFileOutput(imageFileName, Context.MODE_PRIVATE).use { fos ->
bitmapImage.compress(Bitmap.CompressFormat.PNG, 25, fos)
}
return context.filesDir.absolutePath
}
fun getImageFromInternalStorage(context: Context, imageFileName: String): Bitmap? {
val directory = context.filesDir
val file = File(directory, imageFileName)
return BitmapFactory.decodeStream(FileInputStream(file))
}
fun deleteImageFromInternalStorage(context: Context, imageFileName: String): Boolean {
val dir = context.filesDir
val file = File(dir, imageFileName)
return file.delete()
}
}
}

You can't use a foreach statement for that. The foreach is using internally an iterator:
The iterators returned by this class's iterator and listIterator methods are fail-fast: if the list is structurally modified at any time after the iterator is created, in any way except through the iterator's own remove or add methods, the iterator will throw a ConcurrentModificationException.
(From ArrayList javadoc)
In the foreach statement you don't have access to the iterator's add method and in any case that's still not the type of add that you want because it does not append at the end. You'll need to traverse the list manually:
int listSize = list.size();
for(int i = 0; i < listSize; ++i)
list.add("whatever");
Note that this is only efficient for Lists that allow random access. You can check for this feature by checking whether the list implements the RandomAccess marker interface. An ArrayList has random access. A linked list does not.

Another minimalist Python solution without using numpy:
[0 if i < 0 else i for i in a]
No need to define any extra functions.
a = [1, 2, 3, -4, -5.23, 6]
[0 if i < 0 else i for i in a]
yields:
[1, 2, 3, 0, 0, 6]
I think that I also faced this problem, and the best solution I found was to look at my console and figure out the error that was being thrown. So, I read it carefully and found that the problem was that I didn't specify my repo, description, and valid name in my package.json
. I added those pieces of information and everything was okay.
you can use the shell (bash/ksh).
$ var="12345678abc"
$ replace="test"
$ echo ${var//12345678/$replace}

It seems like your Maven is unable to connect to Maven repository at http://repo1.maven.org/maven2.
If you are using proxy and can access the link with browser the same settings need to be applied to Spring Source Tool Suite (if you are running within suite) or Maven.
For Maven proxy setting create a settings.xml
in the .m2
directory with following details
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

</settings>
If you are not using proxy and can access the link with browser, remove any proxy settings described above.
If you want to execute multiple commands in a for loop, you can save the result of find
with mapfile
(bash >= 4) as an variable and go through the array with ${dirlist[@]}
. It also works with directories containing spaces.
The find
command is based on the answer by Boldewyn. Further information about the find
command can be found there.
IFS=""
mapfile -t dirlist < <( find . -maxdepth 1 -mindepth 1 -type d -printf '%f\n' )
for dir in ${dirlist[@]}; do
echo ">${dir}<"
# more commands can go here ...
done
I created function from @Ruel answer. You can use this:
function get_valueFromStringUrl($url , $parameter_name)
{
$parts = parse_url($url);
if(isset($parts['query']))
{
parse_str($parts['query'], $query);
if(isset($query[$parameter_name]))
{
return $query[$parameter_name];
}
else
{
return null;
}
}
else
{
return null;
}
}
Example:
$url = "https://example.com/test/the-page-here/1234?someurl=key&[email protected]";
echo get_valueFromStringUrl($url , "email");
Thanks to @Ruel
Fragments that are hard coded in XML, cannot be replaced. If you need to replace a fragment with another, you should have added them dynamically, first of all.
Note: R.id.fragment_container is a layout or container of your choice in the activity you are bringing the fragment to.
// Create new fragment and transaction
Fragment newFragment = new ExampleFragment();
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack if needed
transaction.replace(R.id.fragment_container, newFragment);
transaction.addToBackStack(null);
// Commit the transaction
transaction.commit();

This answer is just a small tweak of ellemayo's answer. It will automatically update the URL instead of just returning the updated string.
function _updateQueryString(key, value, url) {
if (!url) url = window.location.href;
let updated = ''
var re = new RegExp("([?&])" + key + "=.*?(&|#|$)(.*)", "gi"),
hash;
if (re.test(url)) {
if (typeof value !== 'undefined' && value !== null) {
updated = url.replace(re, '$1' + key + "=" + value + '$2$3');
}
else {
hash = url.split('#');
url = hash[0].replace(re, '$1$3').replace(/(&|\?)$/, '');
if (typeof hash[1] !== 'undefined' && hash[1] !== null) {
url += '#' + hash[1];
}
updated = url;
}
}
else {
if (typeof value !== 'undefined' && value !== null) {
var separator = url.indexOf('?') !== -1 ? '&' : '?';
hash = url.split('#');
url = hash[0] + separator + key + '=' + value;
if (typeof hash[1] !== 'undefined' && hash[1] !== null) {
url += '#' + hash[1];
}
updated = url;
}
else {
updated = url;
}
}
window.history.replaceState({ path: updated }, '', updated);
}
Here is a shorter version of the function presented above:
function getWidth() {
if (self.innerWidth) {
return self.innerWidth;
}
else if (document.documentElement && document.documentElement.clientHeight){
return document.documentElement.clientWidth;
}
else if (document.body) {
return document.body.clientWidth;
}
return 0;

Some more alternative options because regexes (regi ?) are awesome!
Here is a Simple regex to do the job:
regex="[^/]*$"
Example (grep):
FP="/hello/world/my/file/path/hello_my_filename.log"
echo $FP | grep -oP "$regex"
#Or using standard input
grep -oP "$regex" <<< $FP
Example (awk):
echo $FP | awk '{match($1, "$regex",a)}END{print a[0]}
#Or using stardard input
awk '{match($1, "$regex",a)}END{print a[0]} <<< $FP
If you need a more complicated regex: For example your path is wrapped in a string.
StrFP="my string is awesome file: /hello/world/my/file/path/hello_my_filename.log sweet path bro."
#this regex matches a string not containing / and ends with a period
#then at least one word character
#so its useful if you have an extension
regex="[^/]*\.\w{1,}"
#usage
grep -oP "$regex" <<< $StrFP
#alternatively you can get a little more complicated and use lookarounds
#this regex matches a part of a string that starts with / that does not contain a /
##then uses the lazy operator ? to match any character at any amount (as little as possible hence the lazy)
##that is followed by a space
##this allows use to match just a file name in a string with a file path if it has an exntension or not
##also if the path doesnt have file it will match the last directory in the file path
##however this will break if the file path has a space in it.
regex="(?<=/)[^/]*?(?=\s)"
#to fix the above problem you can use sed to remove spaces from the file path only
## as a side note unfortunately sed has limited regex capibility and it must be written out in long hand.
NewStrFP=$(echo $StrFP | sed 's:\(/[a-z]*\)\( \)\([a-z]*/\):\1\3:g')
grep -oP "$regex" <<< $NewStrFP
Total solution with Regexes:
This function can give you the filename with or without extension of a linux filepath even if the filename has multiple "."s in it. It can also handle spaces in the filepath and if the file path is embedded or wrapped in a string.
#you may notice that the sed replace has gotten really crazy looking
#I just added all of the allowed characters in a linux file path
function Get-FileName(){
local FileString="$1"
local NoExtension="$2"
local FileString=$(echo $FileString | sed 's:\(/[a-zA-Z0-9\<\>\|\\\:\)\(\&\;\,\?\*]*\)\( \)\([a-zA-Z0-9\<\>\|\\\:\)\(\&\;\,\?\*]*/\):\1\3:g')
local regex="(?<=/)[^/]*?(?=\s)"
local FileName=$(echo $FileString | grep -oP "$regex")
if [[ "$NoExtension" != "" ]]; then
sed 's:\.[^\.]*$::g' <<< $FileName
else
echo "$FileName"
fi

If you have to mess with a windows path you can start with this one:
[^\\]*$
Works for me:
List<Item> list = Task.Run(() => manager.GetList()).Result;
in this way it is not necessary to mark the method with async in the call.
using str.splitines()
and str.split()
:
In [126]: strs="""A1023 CRT
.....: A1029 Regulator
.....: A1030 Therm"""
In [127]: dict(x.split() for x in strs.splitlines())
Out[127]: {'A1023': 'CRT', 'A1029': 'Regulator', 'A1030': 'Therm'}
str.splitlines([keepends]) -> list of strings
Return a list of the lines in S, breaking at line boundaries. Line breaks are not included in the resulting list unless keepends is given and true.
str.split([sep [,maxsplit]]) -> list of strings
Return a list of the words in the string S, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done. If sep is not specified or is None, any whitespace string is a separator and empty strings are removed from the result.
Total programmatic approach to set rounded corners and add random background color to a View. I have not tested the code, but you get the idea.
GradientDrawable shape = new GradientDrawable();
shape.setCornerRadius( 8 );
// add some color
// You can add your random color generator here
// and set color
if (i % 2 == 0) {
shape.setColor(Color.RED);
} else {
shape.setColor(Color.BLUE);
}
// now find your view and add background to it
View view = (LinearLayout) findViewById( R.id.my_view );
view.setBackground(shape);
Here we are using gradient drawable so that we can make use of GradientDrawable#setCornerRadius
because ShapeDrawable
DOES NOT provide any such method.
I think it depends on the situation but anyway you can use the .toString()
method as it is very clear to understand.

I know this is old, but I would like to suggest using a linear-gradient to achieve the same effect instead of margin offset. This is will maintain any content at its original place.
HTML
<ul>
<li><a href="#">One</a></li>
<li><a href="#">Two</a></li>
<li><a href="#">Three</a></li>
</ul>

ul, li, a {
margin: 0; padding: 0;
}
/* nav stuff */
ul, li, a {
display: inline-block;
text-align: center;
}
/* appearance styling */
ul {
/* hacks to make one side slant only */
overflow: hidden;
background: linear-gradient(to right, red, white, white, red);
}
li {
background-color: red;

You should install IIS sub components from
Control Panel
-> Programs and Features
-> Turn Windows features on or off
Internet Information Services
has subsection World Wide Web Services
/ Application Development Features
There you must check ASP.NET
(.NET Extensibility
, ISAPI Extensions
, ISAPI Filters
will be selected automatically). Double check that specific versions are checked. Under Windows Server 2012 R2, these options are split into 4 & 4.5.
Run from cmd
:
%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -ir
Finally check in IIS manager, that your application uses application pool with .NET framework version v4.0.
Also, look at this answer.
You set the text to a field that was rendered in another instance of your activity residing in cash,say when it was landscape oriented. Then it was recreated due to some reason. You need to set the text in an unusual way by saving the string to SharedPreferences and force relaunch the activity using recreate(), say for mOutputText:
@Override
protected void onResume() {
super.onResume();
String sLcl=mPreferences.getString("response","");
if(!sLcl.isEmpty()){
mOutputText.setText(sLcl);
mPreferences.edit().putString("response","").commit();
}
}
private void changeText() {
mPreferences.edit().putString("response",responseText).commit();
recreate();
}
@Override
protected void onActivityResult(
int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case CAPTURE_MEDIA_RESULT_CODE:
if (null == data || null == data.getData()) {
showMessage("Sorry. You didn't save any video");
} else {
videoUri = data.getData();
mProgress = new ProgressDialog(this);
mProgress.setMessage("Uploading onYoutube ...");
authorizeIt();// SAY YOU CALL THE changeText() at the end of this method
}
break;
}
}
I ran into this issue with OSX.
It seems like a gpg update (of brew) changed to location of gpg
to gpg1
, you can change the binary where git looks up the gpg:
git config --global gpg.program gpg1
If you don't have gpg1: brew install gpg1
.
It looks like gpg1 is being deprecated/"gently nudged out of usage", so you probably should actually update to gpg2, unfortunately this involves quite a few more steps/a bit of time:
brew upgrade gnupg # This has a make step which takes a while
brew link --overwrite gnupg
brew install pinentry-mac
echo "pinentry-program /usr/local/bin/pinentry-mac" >> ~/.gnupg/gpg-agent.conf
killall gpg-agent
The first part installs gpg2, and latter is a hack required to use it. For troubleshooting, see this answer (though that is about linux not brew), it suggests a good test:
echo "test" | gpg --clearsign # on linux it's gpg2 but brew stays as gpg
If this test is successful (no error/output includes PGP signature), you have successfully updated to the latest gpg version.
You should now be able to use git signing again!
It's worth noting you'll need to have:
git config --global gpg.program gpg # perhaps you had this already? On linux maybe gpg2
git config --global commit.gpgsign true # if you want to sign every commit
Note: After you've ran a signed commit, you can verify it signed with:
git log --show-signature -1
which will include gpg info for the last commit.
In Laravel you can add a function inside app/Helper/helper.php like
function formatDate($date = '', $format = 'Y-m-d'){
if($date == '' || $date == null)
return;
return date($format,strtotime($date));
}
And call this function on any controller like this
$start_date = formatDate($start_date,'Y-m-d');
Hope it helps!
You could do:
SELECT
Orders.OrderNumber,
LineItems.Quantity,
LineItems.Description
FROM
Orders INNER JOIN LineItems
ON Orders.OrderID = LineItems.OrderID
WHERE
LineItems.LineItemID = (
SELECT MIN(LineItemID)
FROM LineItems
WHERE OrderID = Orders.OrderID
)
This requires an index (or primary key) on LineItems.LineItemID
and an index on LineItems.OrderID
or it will be slow.
inside the Android manifest file of your project, find the activity declaration of whose you want to fix the orientation and add the following piece of code ,
android:screenOrientation="landscape"
for landscape orientation and for portrait add the following code,
android:screenOrientation="portrait"
Use a controller method if you need to run arbitrary JavaScript code, or you could define a filter that returned true or false.
I just tested (should have done that first), and something like ng-show="!a && b"
worked as expected.
Here is a small jQuery plugin that (among other things) can empty an dropdown list.
Just write:
$('your-select-element').selectUtils('setEmpty');
You can create your <script>
element with an "onload" handler, and that will be called when the script has been loaded and evaluated by the browser.
var script = document.createElement('script');
script.onload = function() {
alert("Script loaded and ready");
};
script.src = "http://whatever.com/the/script.js";
document.getElementsByTagName('head')[0].appendChild(script);
You can't do it synchronously.
edit — it's been pointed out that, true to form, IE doesn't fire a "load" event on <script>
tags being loaded/evaluated. Thus I suppose the next thing to do would be to fetch the script with an XMLHttpRequest and then eval()
it yourself. (Or, I suppose, stuff the text into a <script>
tag you add; the execution environment of eval()
is affected by the local scope, so it won't necessarily do what you want it to do.)
edit — As of early 2013, I'd strongly advise looking into a more robust script loading tool like Requirejs. There are a lot of special cases to worry about. For really simple situations, there's yepnope, which is now built into Modernizr.
DO N'T Use another <application>
tag in manifest file.Just do one change in existing <application>
tag , add this line android:name=".ApplicationName"
where, ApplicationName
will be name of your subclass(use to store global) that, you is about to create.
so, finally your ONE AND ONLY <application>
tag in manifest file should look like this :-
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:theme="@style/Theme.AppCompat.NoActionBar"
android:name=".ApplicationName"

It is mentioned in the .data()
documentation
The data- attributes are pulled in the first time the data property is accessed and then are no longer accessed or mutated (all data values are then stored internally in jQuery)
This was also covered on Why don't changes to jQuery $.fn.data() update the corresponding html 5 data-* attributes?
The demo on my original answer below doesn't seem to work any more.
Updated answer
Again, from the .data()
documentation
The treatment of attributes with embedded dashes was changed in jQuery 1.6 to conform to the W3C HTML5 specification.
So for <div data-role="page"></div>
the following is true $('div').data('role') === 'page'
I'm fairly sure that $('div').data('data-role')
worked in the past but that doesn't seem to be the case any more. I've created a better showcase which logs to HTML rather than having to open up the Console and added an additional example of the multi-hyphen to camelCase data- attributes conversion.
Also see jQuery Data vs Attr?
HTML
<div id="changeMe" data-key="luke" data-another-key="vader"></div>
<a href="#" id="changeData"></a>
<table id="log">
<tr><th>Setter</th><th>Getter</th><th>Result of calling getter</th><th>Notes</th></tr>
</table>
JavaScript (jQuery 1.6.2+)
var $changeMe = $('#changeMe');
var $log = $('#log');
var logger;
(logger = function(setter, getter, note) {
note = note || '';
eval('$changeMe' + setter);
var result = eval('$changeMe' + getter);
$log.append('<tr><td><code>' + setter + '</code></td><td><code>' + getter + '</code></td><td>' + result + '</td><td>' + note + '</td></tr>');
})('', ".data('key')", "Initial value");
$('#changeData').click(function() {
// set data-key to new value
logger(".data('key', 'leia')", ".data('key')", "expect leia on jQuery node object but DOM stays as luke");
// try and set data-key via .attr and get via some methods
logger(".attr('data-key', 'yoda')", ".data('key')", "expect leia (still) on jQuery object but DOM now yoda");
logger("", ".attr('key')", "expect undefined (no attr <code>key</code>)");
logger("", ".attr('data-key')", "expect yoda in DOM and on jQuery object");
// bonus points
logger('', ".data('data-key')", "expect undefined (cannot get via this method)");
logger(".data('anotherKey')", ".data('anotherKey')", "jQuery 1.6+ get multi hyphen <code>data-another-key</code>");
logger(".data('another-key')", ".data('another-key')", "jQuery < 1.6 get multi hyphen <code>data-another-key</code> (also supported in jQuery 1.6+)");
return false;
});
$('#changeData').click();
Original answer
For this HTML:
<div id="foo" data-helptext="bar"></div>
<a href="#" id="changeData">change data value</a>
and this JavaScript (with jQuery 1.6.2)
console.log($('#foo').data('helptext'));
$('#changeData').click(function() {
$('#foo').data('helptext', 'Testing 123');
// $('#foo').attr('data-helptext', 'Testing 123');
console.log($('#foo').data('data-helptext'));
return false;
});
Using the Chrome DevTools Console to inspect the DOM, the $('#foo').data('helptext', 'Testing 123');
does not update the value as seen in the Console but $('#foo').attr('data-helptext', 'Testing 123');
does.
In my case, I had to add _id: Object
into my Schema, and then everything worked fine.
You could try updating the composer:
sudo composer self-update
If that doest works remove composer files & then use: SSH into terminal & type :
$ cd ~
$ sudo curl -sS https://getcomposer.org/installer | sudo php
$ sudo mv composer.phar /usr/local/bin/composer
$ sudo ln -s /usr/local/bin/composer /usr/bin/composer
If you face an error that says: PHP Fatal error: Uncaught exception 'ErrorException' with message 'proc_open(): fork failed - Cannot allocate memory' in phar

To install package use:
composer global require "package-name"

Correct solution is to copy or install to /usr/local/bin
not /usr/bin
.This is due to System Integrity Protection (SIP). SIP makes /usr/bin
read-only but leaves /usr/local
as read-write.
SIP should not be disabled as stated in the answer above because it adds another layer of protection against malware gaining root access. Here is a complete explanation of what SIP does and why it is useful.
As suggested in this answer one should not disable SIP (rootless mode) "It is not recommended to disable rootless mode! The best practice is to install custom stuff to "/usr/local" only."

check out help smooth freq
to see why the above makes a histogram
to deal with ranges just set the xrange variable.
The example method above does not compile. Here is a corrected version (but untested as to whether or not it works.)

Here is a very handy and helpful information about Git Push: Git Push: Just the Tip
The most common use of git push is to push your local changes to your public upstream repository. Assuming that the upstream is a remote named "origin" (the default remote name if your repository is a clone) and the branch to be updated to/from is named "master" (the default branch name), this is done with: git push origin master
git push origin
will push changes from all local branches to matching branches the origin remote.
git push origin master
will push changes from the local master branch to the remote master branch.
git push origin master:staging
will push changes from the local master branch to the remote staging branch if it exists.
If you do not have an LDF file then:
1) put the MDF in the C:\Program Files\Microsoft SQL Server\MSSQL13.SQLEXPRESS\MSSQL\DATA\
2) In ssms, go to Databases -> Attach
and add the MDF file. It will not let you add it this way but it will tell you the database name contained within.
3) Make sure the user you are running ssms.exe as has acccess to this MDF file.
4) Now that you know the DbName, run
EXEC sp_attach_single_file_db @dbname = 'DbName',
@physname = N'C:\Program Files\Microsoft SQL Server\MSSQL13.SQLEXPRESS\MSSQL\DATA\yourfile.mdf';

Tested with a IPA signed with cert1 for app store submission with no devices added in the provisioning profile. Results in a new IPA signed with a enterprise account and a mobile provisioning profile for in house deployment (the mobile provisioning profile gets embedded to the IPA).
Solution:
Unzip the IPA
unzip Application.ipa
Remove old CodeSignature
rm -r "Payload/Application.app/_CodeSignature" "Payload/Application.app/CodeResources" 2> /dev/null | true
Replace embedded mobile provisioning profile
cp "MyEnterprise.mobileprovision" "Payload/Application.app/embedded.mobileprovision"
Re-sign
/usr/bin/codesign -f -s "iPhone Distribution: Certificate Name" --resource-rules "Payload/Application.app/ResourceRules.plist" "Payload/Application.app"
Re-package
zip -qr "Application.resigned.ipa" Payload
Edit: Removed the Entitlement part (see alleys comment, thanks)
You can pass in a pointer to a time_t
object that time
will fill up with the current time (and the return value is the same one that you pointed to). If you pass in NULL
, it just ignores it and merely returns a new time_t
object that represents the current time.
Actually Apache is a web server and Tomcat is an application server. When as HTTP request comes to web server. Then static contents send back to browser by web server. Is there and logic do to done, then that request send to the application server. after processing the logic then response send to web server and send to the client.
Check out section 5.14.2. Moving files and folders (or check out "move" in the Index of the help) of the TortoiseSVN help. You do a move via right-dragging. It also mentions that you need to commit from the parent folder to make it "one" revision. This works for doing the change in a working copy.
(Note that the SVN items in the following image will only show up if the destination folder has already been added to the repository.)
You can also do the move via the Repo Browser (section 5.23. The Repository Browser of the help).
Converted into a convenience extension via Nick's answer:
extension Dictionary {
static func contentsOf(path: URL) -> Dictionary<String, AnyObject> {
let data = try! Data(contentsOf: path)
let plist = try! PropertyListSerialization.propertyList(from: data, options: .mutableContainers, format: nil)
return plist as! [String: AnyObject]
}
}
usage:
let path = Bundle.main.path(forResource: "plistName", ofType: "plist")!
let url = URL(fileURLWithPath: path)
let dict = Dictionary<String, AnyObject>.contentsOf(path: url)
I'd be willing to bet that it would also work to create a similar extension for Arrays
The error "Message: element not interactable" mostly occurs when your element is not clickable or it is not visible yet, and you should click or choose one other element before it. Then your element will get displayed and you can modify it.
You can check if your element is visible or not by calling is_displayed()
method like this:
print("Element is visible? " + str(element_name.is_displayed()))
CURLOPT_USERPWD
basically sends the base64 of the user:password
string with http header like below:
Authorization: Basic dXNlcjpwYXNzd29yZA==
So apart from the CURLOPT_USERPWD
you can also use the HTTP-Request
header option as well like below with other headers:
$headers = array(
'Content-Type:application/json',
'Authorization: Basic '. base64_encode("user:password") // <---
);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
The code below will work just fine in all browsers:
<button onClick="location.href = 'http://www.google.com'">Go to Google</button>
What you're looking for is 'outerHTML', but wee need a fallback coz it's not compatible with old browsers.
var getString = (function() {
var DIV = document.createElement("div");
if ('outerHTML' in DIV)
return function(node) {
return node.outerHTML;
};
return function(node) {
var div = DIV.cloneNode();
div.appendChild(node.cloneNode(true));
return div.innerHTML;
};
})();
// getString(el) == "<p>Test</p>"

Instead of running perror
on any error code you get, you can retrieve a complete listing of errno
values on your system with the following one-liner:
cpp -dM /usr/include/errno.h | grep 'define E' | sort -n -k 3
Additionally, if you want the flexibility of choosing the width
, you can choose between one of the following two formats (with or without truncation):
int width = 30;
// No truncation uses %-*s
printf( "%-*s %s\n", width, "Starting initialization...", "Ok." );
// Output is "Starting initialization... Ok."
// Truncated to the specified width uses %-.*s
printf( "%-.*s %s\n", width, "Starting initialization...", "Ok." );
// Output is "Starting initialization... Ok."
display: inline-flex
does not make flex items display inline. It makes the flex container display inline. That is the only difference between display: inline-flex
and display: flex
. A similar comparison can be made between display: inline-block
and display: block
, and pretty much any other display type that has an inline counterpart.1
There is absolutely no difference in the effect on flex items; flex layout is identical whether the flex container is block-level or inline-level. In particular, the flex items themselves always behave like block-level boxes (although they do have some properties of inline-blocks). You cannot display flex items inline; otherwise you don't actually have a flex layout.
It is not clear what exactly you mean by "vertically align" or why exactly you want to display the contents inline, but I suspect that flexbox is not the right tool for whatever you are trying to accomplish. Chances are what you're looking for is just plain old inline layout (display: inline
and/or display: inline-block
), for which flexbox is not a replacement; flexbox is not the universal layout solution that everyone claims it is (I'm stating this because the misconception is probably why you're considering flexbox in the first place).
1 The differences between block layout and inline layout are outside the scope of this question, but the one that stands out the most is auto width: block-level boxes stretch horizontally to fill their containing block, whereas inline-level boxes shrink to fit their contents. In fact, it is for this reason alone you will almost never use display: inline-flex
unless you have a very good reason to display your flex container inline.

Here is a link to another similar SO question, which has an answer pointing to this good article on "Reading, writing and photo metadata" in .Net.
You are confusing 'sets' and 'lists'. A set does not guarantee order, but lists do.
Sets are declared using curly brackets: {}
. In contrast, lists are declared using square brackets: []
.
mySet = {a, b, c, c}
Does not guarantee order, but list does:
myList = [a, b, c]
alert( JSON.stringify(product) );
Sometimes you can have multiple fields with similar validation in your application. In such a case I recommend to create common component field where you keep this validation.
For instance, let's assume that you have mandatory text input in a few places in your application. You can create a TextInput component:
constructor(props) {
super(props);
this.state = {
touched: false, error: '', class: '', value: ''
}
}
onValueChanged = (event) => {
let [error, validClass, value] = ["", "", event.target.value];
[error, validClass] = (!value && this.props.required) ?
["Value cannot be empty", "is-invalid"] : ["", "is-valid"]
this.props.onChange({value: value, error: error});
this.setState({
touched: true,
error: error,
class: validClass,
value: value
})
}
render() {
return (
<div>
<input type="text"
value={this.props.value}
onChange={this.onValueChanged}
className={"form-control " + this.state.class}
id="{this.props.id}"
placeholder={this.props.placeholder} />
{this.state.error ?
<div className="invalid-feedback">
{this.state.error}
</div> : null
}
</div>
)
}
And then you can use such a component anywhere in your application:
constructor(props) {
super(props);
this.state = {
user: {firstName: '', lastName: ''},
formState: {
firstName: { error: '' },
lastName: { error: '' }
}
}
}
onFirstNameChange = (model) => {
let user = this.state.user;
user.firstName = model.value;
this.setState({
user: user,
formState: {...this.state.formState, firstName: { error: model.error }}
})
}
onLastNameChange = (model) => {
let user = this.state.user;
user.lastName = model.value;
this.setState({
user: user,
formState: {...this.state.formState, lastName: { error: model.error }}
})
}
onSubmit = (e) => {
// submit logic
}
render() {
return (
<form onSubmit={this.onSubmit}>
<TextInput id="input_firstName"
value={this.state.user.firstName}
onChange={this.onFirstNameChange}
required = {true}
placeholder="First name" />
<TextInput id="input_lastName"
value={this.state.user.lastName}
onChange={this.onLastNameChange}
required = {true}
placeholder="Last name" />
{this.state.formState.firstName.error || this.state.formState.lastName.error ?
<button type="submit" disabled className="btn btn-primary margin-left disabled">Save</button>
: <button type="submit" className="btn btn-primary margin-left">Save</button>
}
</form>
)
}
Benefits:
First Way:
You didn't create the directory. Also, you are passing an absolute path to openFileOutput()
, which is wrong.
Second way:
You created an empty file with the desired name, which then prevented you from creating the directory. Also, you are passing an absolute path to openFileOutput()
, which is wrong.
Third way:
You didn't create the directory. Also, you are passing an absolute path to openFileOutput()
, which is wrong.
Fourth Way:
You didn't create the directory. Also, you are passing an absolute path to openFileOutput()
, which is wrong.
Fifth way:
You didn't create the directory. Also, you are passing an absolute path to openFileOutput()
, which is wrong.
Correct way:
File
for your desired directory (e.g., File path=new File(getFilesDir(),"myfolder");
)mkdirs()
on that File
to create the directory if it does not existFile
for the output file (e.g., File mypath=new File(path,"myfile.txt");
)File
(e.g., using new BufferedWriter(new FileWriter(mypath))
)Another alternative is numpy.broadcast_to(val,n)
which returns in constant time regardless of the size and is also the most memory efficient (it returns a view of the repeated element). The caveat is that the returned value is read-only.
Below is a comparison of the performances of all the other methods that have been proposed using the same benchmark as in Nico Schlömer's answer.
I found that this can be done rather simple using the ".values" method, which also gives named fields:
result_list = list(my_queryset.values('first_named_field', 'second_named_field'))
return HttpResponse(json.dumps(result_list))
"list" must be used to get data as iterable, since the "value queryset" type is only a dict if picked up as an iterable.

I also met the case to use both python2 and python3 on my Windows machine. Here's how i resolved it:
C:\Python35;C:\Python35\Scripts;C:\Python27;C:\Python27\Scripts
to environment variable PATH
.C:\Python35
to rename python.exe
to python3.exe
, also to C:\Python27
, rename python.exe
to python2.exe
.python2 scriptname.py
, or python3 scriptname.py
in command line to switch the version you like.If you only want to read the first 999,999 (non-header) rows:
read_csv(..., nrows=999999)
If you only want to read rows 1,000,000 ... 1,999,999
read_csv(..., skiprows=1000000, nrows=999999)
nrows : int, default None Number of rows of file to read. Useful for reading pieces of large files*
skiprows : list-like or integer Row numbers to skip (0-indexed) or number of rows to skip (int) at the start of the file
and for large files, you'll probably also want to use chunksize:
chunksize : int, default None Return TextFileReader object for iteration
For me docker system prune
did the trick. I`m running mac os.
Quoting API on referencedColumnName:
The name of the column referenced by this foreign key column.
Default (only applies if single join column is being used): The same name as the primary key column of the referenced table.
Where this would be used?
When there is a composite PK in referenced table, then you need to specify column name you are referencing.
Use hsh.delete_if. In your specific case, something like: hsh.delete_if { |k, v| v.empty? }
Using Lodash
var array = [
{ "name": "Joe", "age": 17 },
{ "name": "Bob", "age": 17 },
{ "name": "Carl", "age": 35 }
];
_.chain(array).map('age').unique().value();
Returns [17,35]
Use Google Sheets and import the CSV file.
Then you can export that to use in Excel
I suppose this would help:
<%!
String someOutput() {
return "Some Output";
}
%>
...
<%= someOutput() %>
Anyway, it isn't a good idea to have code in a view.
import traceback
traceback.print_stack()
Since they are running on different ports, they are different JavaScript origin
. It doesn't matter that they are on the same machine/hostname.
You need to enable CORS on the server (localhost:8080). Check out this site: http://enable-cors.org/
All you need to do is add an HTTP header to the server:
Access-Control-Allow-Origin: http://localhost:3000
Or, for simplicity:
Access-Control-Allow-Origin: *
Thought don't use "*" if your server is trying to set cookie and you use withCredentials = true
when responding to a credentialed request, server must specify a domain, and cannot use wild carding.
Here is @Vitaliy Gozhenko's answer, in Swift.
To summarize you will create a UITableViewHeaderFooterView that contains a UITableViewCell. This UITableViewCell will be "dequeuable" and you can design it in your storyboard.
Create a UITableViewHeaderFooterView class
class CustomHeaderFooterView: UITableViewHeaderFooterView {
var cell : UITableViewCell? {
willSet {
cell?.removeFromSuperview()
}
didSet {
if let cell = cell {
cell.frame = self.bounds
cell.autoresizingMask = [UIViewAutoresizing.FlexibleHeight, UIViewAutoresizing.FlexibleWidth]
self.contentView.backgroundColor = UIColor .clearColor()
self.contentView .addSubview(cell)
}
}
}
Plug your tableview with this class in your viewDidLoad function:
self.tableView.registerClass(CustomHeaderFooterView.self, forHeaderFooterViewReuseIdentifier: "SECTION_ID")
When asking, for a section header, dequeue a CustomHeaderFooterView, and insert a cell into it
func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
let view = self.tableView.dequeueReusableHeaderFooterViewWithIdentifier("SECTION_ID") as! CustomHeaderFooterView
if view.cell == nil {
let cell = self.tableView.dequeueReusableCellWithIdentifier("Cell")
view.cell = cell;
}
// Fill the cell with data here
return view;
}

I actually tried to implement connection pooling on the django end using:
https://github.com/gmcguire/django-db-pool
but I still received this error, despite lowering the number of connections available to below the standard development DB quota of 20 open connections.
There is an article here about how to move your postgresql database to the free/cheap tier of Amazon RDS. This would allow you to set max_connections
higher. This will also allow you to pool connections at the database level using PGBouncer.
https://www.lewagon.com/blog/how-to-migrate-heroku-postgres-database-to-amazon-rds
UPDATE:
Heroku responded to my open ticket and stated that my database was improperly load balanced in their network. They said that improvements to their system should prevent similar problems in the future. Nonetheless, support manually relocated my database and performance is noticeably improved.
in spring boot project we can write logging.level.root=WARN but here problem is, we have to restart again even we added devtools dependency, in property file if we are modified any value will not autodetectable, for this limitation i came to know the solution i,e we can add actuator in pom.xml and pass the logger level as below shown in postman client in url bar http://localhost:8080/loggers/ROOT or http://localhost:8080/loggers/com.mycompany and in the body you can pass the json format like below
{
"configuredLevel": "WARN"
}
Try with this solution: http://phppot.com/php/sorting-mysql-row-order-using-jquery/ where new order is saved in some HMTL element. Then you submit the form with this data to some PHP script, and iterate trough it with for loop.
Note: I had to add another db field of type INT(11) which is updated(timestamp'ed) on each iteration - it serves for script to know which row is recenty updated, or else you end up with scrambled results.
According to this :
SmtpClient and its network of types are poorly designed, we strongly recommend you use https://github.com/jstedfast/MailKit and https://github.com/jstedfast/MimeKit instead.
Reference : https://docs.microsoft.com/en-us/dotnet/api/system.net.mail.smtpclient?view=netframework-4.8
It's better to use MailKit
to send emails :
var message = new MimeMessage ();
message.From.Add (new MailboxAddress ("Joey Tribbiani", "[email protected]"));
message.To.Add (new MailboxAddress ("Mrs. Chanandler Bong", "[email protected]"));
message.Subject = "How you doin'?";
message.Body = new TextPart ("plain") {
Text = @"Hey Chandler,
I just wanted to let you know that Monica and I were going to go play some paintball, you in?
-- Joey"
};
using (var client = new SmtpClient ()) {
// For demo-purposes, accept all SSL certificates (in case the server supports STARTTLS)
client.ServerCertificateValidationCallback = (s,c,h,e) => true;
client.Connect ("smtp.friends.com", 587, false);
// Note: only needed if the SMTP server requires authentication
client.Authenticate ("joey", "password");
client.Send (message);
client.Disconnect (true);
}
Keep in mind that the Rewrite engine only kicks in once the HTTP request has been received - which means you would still need a certificate, in order for the client to set up the connection to send the request over!
However if the backup machine will appear to have the same hostname (as far as the client is concerned), then there should be no reason you can't use the same certificate as the main production machine.
I had a similar problem at NPM modules won't install globally without sudo, the issue was that when i installed node i did it with sudo via chris/lea ppa repo.
My solution was to uninstall node and then install it this way:
Download latest stable node sources from nodejs.org #in my case node-v0.10.20.tar.gz
tar -zxf node-v0.10.20.tar.gz #uncompress sources
cd node-v0.10.20 #enter uncompressed folder
sudo chown $USER -R /usr/local
./configure --prefix=/usr/local && make && make install
PD: If you don't want to change ownership of the /usr/local folder, you can install it somewhere you already own. The problem of this approach is that you will have to bind the installation folder with the bash command line so that we can use the node command later on
mkdir ~/opt
./configure --prefix=~/opt && make && make install
echo 'export PATH=~/opt/bin:${PATH}' >> ~/.bashrc #or ~/.profile or ~/.bash_profile or ~/.zshenv depending on the current Operative System
With either of those approaches, you will be able to do the following without using sudo
npm install -g module_to_install
According to HTML 5.2:
When specified on an element, [the
hidden
attribute] indicates that the element is not yet, or is no longer, directly relevant to the page’s current state, or that it is being used to declare content to be reused by other parts of the page as opposed to being directly accessed by the user.
Examples include a tab list where some panels are not exposed, or a log-in screen that goes away after a user logs in. I like to call these things “temporally relevant” i.e. they are relevant based on timing.
On the other hand, ARIA 1.1 says:
[The
aria-hidden
state] indicates whether an element is exposed to the accessibility API.
In other words, elements with aria-hidden="true"
are removed from the accessibility tree, which most assistive technology honors, and elements with aria-hidden="false"
will definitely be exposed to the tree. Elements without the aria-hidden
attribute are in the "undefined (default)" state, which means user agents should expose it to the tree based on its rendering. E.g. a user agent may decide to remove it if its text color matches its background color.
Now let’s compare semantics. It’s appropriate to use hidden
, but not aria-hidden
, for an element that is not yet “temporally relevant”, but that might become relevant in the future (in which case you would use dynamic scripts to remove the hidden
attribute). Conversely, it’s appropriate to use aria-hidden
, but not hidden
, on an element that is always relevant, but with which you don’t want to clutter the accessibility API; such elements might include “visual flair”, like icons and/or imagery that are not essential for the user to consume.
The semantics have predictable effects in browsers/user agents. The reason I make a distinction is that user agent behavior is recommended, but not required by the specifications.
The hidden
attribute should hide an element from all presentations, including printers and screen readers (assuming these devices honor the HTML specs). If you want to remove an element from the accessibility tree as well as visual media, hidden
would do the trick. However, do not use hidden
just because you want this effect. Ask yourself if hidden
is semantically correct first (see above). If hidden
is not semantically correct, but you still want to visually hide the element, you can use other techniques such as CSS.
Elements with aria-hidden="true"
are not exposed to the accessibility tree, so for example, screen readers won’t announce them. This technique should be used carefully, as it will provide different experiences to different users: accessible user agents won’t announce/render them, but they are still rendered on visual agents. This can be a good thing when done correctly, but it has the potential to be abused.
Lastly, there is a difference in syntax between the two attributes.
hidden
is a boolean attribute, meaning if the attribute is present it is true—regardless of whatever value it might have—and if the attribute is absent it is false. For the true case, the best practice is to either use no value at all (<div hidden>...</div>
), or the empty string value (<div hidden="">...</div>
). I would not recommend hidden="true"
because someone reading/updating your code might infer that hidden="false"
would have the opposite effect, which is simply incorrect.
aria-hidden
, by contrast, is an enumerated attribute, allowing one of a finite list of values. If the aria-hidden
attribute is present, its value must be either "true"
or "false"
. If you want the "undefined (default)" state, remove the attribute altogether.

xhr.getResponseHeader('Set-Cookie');
It won't work for me.
I use this
function getCookie(cname) {
var name = cname + "=";
var ca = document.cookie.split(';');
for(var i=0; i<ca.length; i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1);
if (c.indexOf(name) != -1) return c.substring(name.length,c.length);
}
return "";
}
success: function(output, status, xhr) {
alert(getCookie("MyCookie"));
},
First step: see if postgres has a repository with prebuilt binaries for the version you want for your OS: https://www.postgresql.org/download/
If that doesn't work (for instance if your distro is there but is no longer supported, so correct binaries aren't provided for it), or if you just want to go straight or the source and not have to worry about adding remote repo's, etc.
What I did is download the raw source of postgres for the desired version.
Untar it, cd into it, build it ./configure && make
, then:
postgresql-12.3 $ find . -name pg_dump
./src/bin/pg_dump/pg_dump
$ ./src/bin/pg_dump/pg_dump
unable to load libpg.so.5 # if it says this...
$ find . -name libpg.so.5
$ export LD_LIBRARY_PATH=/your/path/to/the/shared/dir/of/above/file
$ ./src/bin/pg_dump/pg_dump # works now
Now you have access to any version that builds on your box. Which should be any.
your understanding is right. For detailed info on {} see bash ref - parameter expansion
'for' and 'while' have different syntax and offer different styles of programmer control for an iteration. Most non-asm languages offer a similar syntax.
With while, you would probably write i=0; while [ $i -lt 10 ]; do echo $i; i=$(( i + 1 )); done
in essence manage everything about the iteration yourself
You can use :
var placeholder = 'search here';
$('#search').focus(function(){
if ($.trim($(this).val()) === placeholder){
this.value ='';
}
}).blur(function(){
if ($.trim($(this).val()) === ''){
this.value = placeholder;
}
}).val(placeholder);
use DECIMAL()
or NUMERIC()
as they are fixed precision and scale numbers.
SELECT fullName,
CAST(totalBal as DECIMAL(9,2)) _totalBal
FROM client_info
ORDER BY _totalBal DESC
If you are using the fixed pipeline (OpenGL < 3.3) or the compatibility profile you can use
//Turn on wireframe mode
glPolygonMode(GL_FRONT_AND_BACK, GL_LINE);
//Draw the scene with polygons as lines (wireframe)
renderScene();
//Turn off wireframe mode
glPolygonMode(GL_FRONT_AND_BACK, GL_FILL);
In this case you can change the line width by calling glLineWidth
Otherwise you need to change the polygon mode inside your draw method (glDrawElements, glDrawArrays, etc) and you may end up with some rough results because your vertex data is for triangles and you are outputting lines. For best results consider using a Geometry shader or creating new data for the wireframe.
If you want to enable general error logs and slow query error log in the table instead of file
To start logging in table instead of file:
set global log_output = “TABLE”;
To enable general and slow query log:
set global general_log = 1;
set global slow_query_log = 1;
To view the logs:
select * from mysql.slow_log;
select * from mysql.general_log;

There are many ways to update the rows.
When it comes to UPDATE
the rows using subqueries, you can use any of these approaches.
UPDATE
<table1>
SET
customer=<table2>.customer,
address=<table2>.address,
partn=<table2>.partn
FROM
<table2>
WHERE
<table1>.address_id=<table2>.address_i;
Explanation:
table1
is the table which we want to update,table2
is the table, from which we'll get the value to be replaced/updated. We are usingFROM
clause, to fetch thetable2
's data.WHERE
clause will help to set the proper data mapping.
UPDATE
<table1>
SET
customer=subquery.customer,
address=subquery.address,
partn=subquery.partn
FROM
(
SELECT
address_id, customer, address, partn
FROM /* big hairy SQL */ ...
) AS subquery
WHERE
dummy.address_id=subquery.address_id;
Explanation: Here we are using subquerie inside the
FROM
clause, and giving an alias to it. So that it will act like the table.
UPDATE
<table1>
SET
customer=<table2>.customer,
address=<table2>.address,
partn=<table2>.partn
FROM
<table2> as t2
JOIN <table3> as t3
ON
t2.id = t3.id
WHERE
<table1>.address_id=<table2>.address_i;
Explanation: Sometimes we face the situation in that table join is so important to get proper data for the update. To do so, Postgres allows us to Join multiple tables inside the
FROM
clause.
Approach-4 [Using WITH statement]
WITH subquery AS (
SELECT
address_id,
customer,
address,
partn
FROM
<table1>;
)
UPDATE <table-X>
SET customer = subquery.customer,
address = subquery.address,
partn = subquery.partn
FROM subquery
WHERE <table-X>.address_id = subquery.address_id;
WITH subquery AS (
SELECT address_id, customer, address, partn
FROM
<table1> as t1
JOIN
<table2> as t2
ON
t1.id = t2.id;
-- You can build as COMPLEX as this query as per your need.
)
UPDATE <table-X>
SET customer = subquery.customer,
address = subquery.address,
partn = subquery.partn
FROM subquery
WHERE <table-X>.address_id = subquery.address_id;
Explanation: From Postgres 9.1, this(
WITH
) concept has been introduces. Using that We can make any complex queries and generate desire result. Here we are using this approach to update the table.
I hope, this would be helpful.
Here's a good discussion on this:
Basically you should
function chunkArrayInGroups(arr, size) {
var newArr=[];
for (var i=0; arr.length>size; i++){
newArr.push(arr.splice(0,size));
}
newArr.push(arr.slice(0));
return newArr;
}
chunkArrayInGroups([0, 1, 2, 3, 4, 5, 6], 3);
Getting SOAP working usually does not require compiling PHP from source. I would recommend trying that only as a last option.
For good measure, check to see what your phpinfo says, if anything, about SOAP extensions:
$ php -i | grep -i soap
to ensure that it is the PHP extension that is missing.
Assuming you do not see anything about SOAP in the phpinfo, see what PHP SOAP packages might be available to you.
In Ubuntu/Debian you can search with:
$ apt-cache search php | grep -i soap
or in RHEL/Fedora you can search with:
$ yum search php | grep -i soap
There are usually two PHP SOAP packages available to you, usually php-soap
and php-nusoap
. php-soap
is typically what you get with configuring PHP with --enable-soap
.
In Ubuntu/Debian you can install with:
$ sudo apt-get install php-soap
Or in RHEL/Fedora you can install with:
$ sudo yum install php-soap
After the installation, you might need to place an ini file and restart Apache.
RENAME TABLE old_table_name TO new_table_name;
I used a form with a single submit button. Point the "action" attribute to the ID of the element that needs to be navigated to. Worked for me with just "#top" without needing to define an ID in my stylesheet:
<form action="#top">
<button type="submit">Back to Top</button>
</form>
Maybe a couple extra lines than is desirable but it's a button, at least. I find this the most concise and descriptive way to go about it.
You can use text
.
text(x, y, s, fontsize=12)
text
coordinates can be given relative to the axis, so the position of your text will be independent of the size of the plot:
The default transform specifies that text is in data coords, alternatively, you can specify text in axis coords (0,0 is lower-left and 1,1 is upper-right). The example below places text in the center of the axes::
text(0.5, 0.5,'matplotlib',
horizontalalignment='center',
verticalalignment='center',
transform = ax.transAxes)
To prevent the text to interfere with any point of your scatter is more difficult afaik. The easier method is to set y_axis (ymax in ylim((ymin,ymax))
) to a value a bit higher than the max y-coordinate of your points. In this way you will always have this free space for the text.
EDIT: here you have an example:
In [17]: from pylab import figure, text, scatter, show
In [18]: f = figure()
In [19]: ax = f.add_subplot(111)
In [20]: scatter([3,5,2,6,8],[5,3,2,1,5])
Out[20]: <matplotlib.collections.CircleCollection object at 0x0000000007439A90>
In [21]: text(0.1, 0.9,'matplotlib', ha='center', va='center', transform=ax.transAxes)
Out[21]: <matplotlib.text.Text object at 0x0000000007415B38>
In [22]:
The ha and va parameters set the alignment of your text relative to the insertion point. ie. ha='left' is a good set to prevent a long text to go out of the left axis when the frame is reduced (made narrower) manually.
For a shorten version. If all the indices are smaller than 10, then use the following:
do i=0,9
fid=100+i
fname='OUTPUT'//NCHAR(i+48) //'.txt'
open(fid, file=fname)
!....
end do
For a general version:
character(len=5) :: charI
do i = 0,100
fid = 100 + i
write(charI,"(A)"), i
fname ='OUTPUT' // trim(charI) // '.txt'
open(fid, file=fname)
end do
That's all.
If you need autocomplete support from within in your templates from the Angular Language Service:
Synchronous:
myVar = { hello: '' };
<ng-container *ngIf="myVar; let var;">
{{var.hello}}
</ng-container>
Using async pipe:
myVar$ = of({ hello: '' });
<ng-container *ngIf="myVar$ | async; let var;">
{{var.hello}}
</ng-container>
No need to go in such deep technicalities, and get yourself blasted. Let me explain it in the most easiest way. We all have studied "Sets" during our school-age in Mathematics. Just consider 3D numpy array as the formation of "sets".
x = np.zeros((2,3,4))
Simply Means:
2 Sets, 3 Rows per Set, 4 Columns
Example:
Input
x = np.zeros((2,3,4))
Output
Set # 1 ---- [[[ 0., 0., 0., 0.], ---- Row 1
[ 0., 0., 0., 0.], ---- Row 2
[ 0., 0., 0., 0.]], ---- Row 3
Set # 2 ---- [[ 0., 0., 0., 0.], ---- Row 1
[ 0., 0., 0., 0.], ---- Row 2
[ 0., 0., 0., 0.]]] ---- Row 3
Explanation: See? we have 2 Sets, 3 Rows per Set, and 4 Columns.
Note: Whenever you see a "Set of numbers" closed in double brackets from both ends. Consider it as a "set". And 3D and 3D+ arrays are always built on these "sets".
You should try
if (row.Table.Columns.Contains("US_OTHERFRIEND"))
I don't believe that row has a columns property itself.
UPDATE
While these methods work, newer versions of VS Code uses the Ctrl+] shortcut to indent a block of code once, and Ctrl+[ to remove indentation.
This method detects the indentation in a file and indents accordingly.You can change the size of indentation by clicking on the Select Indentation setting in the bottom right of VS Code (looks something like "Spaces: 2"), selecting "Indent using Spaces" from the drop-down menu and then selecting by how many spaces you would like to indent.
I prefer Scanner
because it doesn't throw checked exceptions and therefore it's usage results in a more streamlined code.
Using set_time_limit(0)
is useless when using php-fpm or similar process manager.
Bottomline is not to use set_time_limit
when using php-fpm
, to increase your execution timeout, check this tutorial.
Intent service is child of Service
IntentService: If you want to download a bunch of images at the start of opening your app. It's a one-time process and can clean itself up once everything is downloaded.
Service: A Service which will constantly be used to communicate between your app and back-end with web API calls. Even if it is finished with its current task, you still want it to be around a few minutes later, for more communication
This ought to be good for you:
Make sure you download the wkhtmltoimage distribution!
I wrote a library which makes working with json data and deserialization a breeze in Swift. You can get it here: https://github.com/isair/JSONHelper
Edit: I updated my library, you can now do it with just this:
class Business: Deserializable {
var id: Int?
var name = "N/A" // This one has a default value.
required init(data: [String: AnyObject]) {
id <-- data["id"]
name <-- data["name"]
}
}
var businesses: [Business]()
Alamofire.request(.GET, "http://MyWebService/").responseString { (request, response, string, error) in
businesses <-- string
}
Old Answer:
First, instead of using .responseString, use .response to get a response object. Then change your code to:
func getAllBusinesses() {
Alamofire.request(.GET, "http://MyWebService/").response { (request, response, data, error) in
var businesses: [Business]?
businesses <-- data
if businesses == nil {
// Data was not structured as expected and deserialization failed, do something.
} else {
// Do something with your businesses array.
}
}
}
And you need to make a Business class like this:
class Business: Deserializable {
var id: Int?
var name = "N/A" // This one has a default value.
required init(data: [String: AnyObject]) {
id <-- data["id"]
name <-- data["name"]
}
}

If you are trying to simply return a string to a View, try this:
public string Test()
{
return "test";
}
This will return a view with the word test in it. You can insert some html in the string.
You can also try this:
public ActionResult Index()
{
return Content("<html><b>test</b></html>");
}
return el instanceof jQuery ? el.size() > 0 : (el && el.tagName);
Take away the spaces. So do:
matches <- unique(grep("A1|A9|A6", myfile$Letter, value=TRUE, fixed=TRUE))
from pandas import DataFrame
import pandas as pd

test = df.sort_values(['one'], ascending=False)

You've probably heard of Bluestacks, and actually you can run and debug your android apps on the Bluestacks emulator. I think this is the best solution to the slow Android Studios emulator speed. Also next time think about buying an Intel processor instead. Look here for more information: Connect Bluestacks to Android Studio
First, make sure you have the following address in your Environment Variables
Path
C:\Program Files (x86)\Microsoft SDKs\TypeScript\2.0
Then open your Command Prompt
and type the following command:
tsc -v
If you get this error while using manage.py shell
, one possible reason is that you have a development server running (manage.py runserver
) which is locking the database. Stoping the server while using the shell has always fixed the problem for me.
As everyone else here has stated: You cannot upload just any file automatically with JavaScript.
HOWEVER! If you have access to the information you want to send in your code (i.e., not C:\passwords.txt
), then you can upload it as a blob-type, and then treat it as a file.
What the server will end up seeing will be indistinguishable from someone actually setting the value of <input type="file" />
. The trick, ultimately, is to begin a new XMLHttpRequest()
with the server...
function uploadFile (data) {
// define data and connections
var blob = new Blob([JSON.stringify(data)]);
var url = URL.createObjectURL(blob);
var xhr = new XMLHttpRequest();
xhr.open('POST', 'myForm.php', true);
// define new form
var formData = new FormData();
formData.append('someUploadIdentifier', blob, 'someFileName.json');
// action after uploading happens
xhr.onload = function(e) {
console.log("File uploading completed!");
};
// do the uploading
console.log("File uploading started!");
xhr.send(formData);
}
// This data/text below is local to the JS script, so we are allowed to send it!
uploadFile({'hello!':'how are you?'});
So, what could you possibly use this for? I use it for uploading HTML5 canvas elements as jpg's. This saves the user the trouble of having to open a file
input
element, only to select the local, cached image that they just resized, modified, etc.. But it should work for any file type.
You can use the following to get the previous URL.
var oldURL = document.referrer;
alert(oldURL);
You dont need to define option tags, you can do this using the ngOptions directive: https://docs.angularjs.org/api/ng/directive/ngOptions
<select class="form-control" ng-change="unitChanged()" ng-model="data.unit" ng-options="unit.id as unit.label for unit in units"></select>
In order to give a value in the table, we need to give a command:
php artisan make:migration create_users_table
and after then this command line
php artisan migrate
......
You can fetch the list of tables and schemata by querying the SQLITE_MASTER table:
sqlite> .tab
job snmptarget t1 t2 t3
sqlite> select name from sqlite_master where type = 'table';
job
t1
t2
snmptarget
t3
sqlite> .schema job
CREATE TABLE job (
id INTEGER PRIMARY KEY,
data VARCHAR
);
sqlite> select sql from sqlite_master where type = 'table' and name = 'job';
CREATE TABLE job (
id INTEGER PRIMARY KEY,
data VARCHAR
)
Think of it as the natural orthogonal operation to split.
I understand why it is applicable to anything iterable and so can't easily be implemented just on list.
For readability, I'd like to see it in the language but I don't think that is actually feasible - if iterability were an interface then it could be added to the interface but it is just a convention and so there's no central way to add it to the set of things which are iterable.
If you want to check if some string is present in another string, use something like String.contains
If you want to check if some pattern is present in a string, append and prepend the pattern with '.*'. The result will accept strings that contain the pattern.
Example: Suppose you have some regex a(b|c) that checks if a string matches ab
or ac
.*(a(b|c)).*
will check if a string contains a ab
or ac
.
A disadvantage of this method is that it will not give you the location of the match.

Up to C#5 (-VS2013) you have to call a function/method for it. Either a "normal" function such as String.Format
or an overload of the + operator.
string str = "Hello " + name; // This calls an overload of operator +.
In C#6 (VS2015) string interpolation has been introduced (as described by other answers).

sort
has been replaced in v0.20 by DataFrame.sort_values
and DataFrame.sort_index
. Aside from this, we also have argsort
.
Here are some common use cases in sorting, and how to solve them using the sorting functions in the current API. First, the setup.
# Setup
np.random.seed(0)
df = pd.DataFrame({'A': list('accab'), 'B': np.random.choice(10, 5)})
df
A B
0 a 7
1 c 9
2 c 3
3 a 5
4 b 2
For example, to sort df
by column "A", use sort_values
with a single column name:
df.sort_values(by='A')
A B
0 a 7
3 a 5
4 b 2
1 c 9
2 c 3
If you need a fresh RangeIndex, use DataFrame.reset_index
.
For example, to sort by both col "A" and "B" in df
, you can pass a list to sort_values
:
df.sort_values(by=['A', 'B'])
A B
3 a 5
0 a 7
4 b 2
2 c 3
1 c 9
df2 = df.sample(frac=1)
df2
A B
1 c 9
0 a 7
2 c 3
3 a 5
4 b 2
You can do this using sort_index
:
df2.sort_index()
A B
0 a 7
1 c 9
2 c 3
3 a 5
4 b 2
df.equals(df2)
# False
df.equals(df2.sort_index())
# True
Here are some comparable methods with their performance:
%timeit df2.sort_index()
%timeit df2.iloc[df2.index.argsort()]
%timeit df2.reindex(np.sort(df2.index))
605 µs ± 13.6 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
610 µs ± 24.2 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
581 µs ± 7.63 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)
For example,
idx = df2.index.argsort()
idx
# array([0, 7, 2, 3, 9, 4, 5, 6, 8, 1])
This "sorting" problem is actually a simple indexing problem. Just passing integer labels to iloc
will do.
df.iloc[idx]
A B
1 c 9
0 a 7
2 c 3
3 a 5
4 b 2
You can do it by making the background into a pattern:
<defs>
<pattern id="img1" patternUnits="userSpaceOnUse" width="100" height="100">
<image href="wall.jpg" x="0" y="0" width="100" height="100" />
</pattern>
</defs>
Adjust the width and height according to your image, then reference it from the path like this:
<path d="M5,50
l0,100 l100,0 l0,-100 l-100,0
M215,100
a50,50 0 1 1 -100,0 50,50 0 1 1 100,0
M265,50
l50,100 l-100,0 l50,-100
z"
fill="url(#img1)" />
what about this
--// Convert NVARCHAR to DATETIME
DECLARE @date DATETIME = (SELECT convert(DATETIME, '2013-08-29 13:55:48', 120))
--// Convert DATETIME to custom NVARCHAR FORMAT
SELECT
RIGHT('00'+ CAST(DAY(@date) AS NVARCHAR),2) + '-' +
RIGHT('00'+ CAST(MONTH(@date) AS NVARCHAR),2) + '-' +
CAST(YEAR(@date) AS NVARCHAR) + ' ' +
CAST(CONVERT(TIME,@date) AS NVARCHAR)
result: '29-08-2013 13:55:48.0000000'
I just love getting information like BalusC gives here - and he is kind enough to help SO many people with such GOOD information that I regard his words as gospel, but I was not able to use that order of events to solve this same kind of timing issue in my project. Since BalusC put a great general reference here that I even bookmarked, I thought I would donate my solution for some advanced timing issues in the same place since it does solve the original poster's timing issues as well. I hope this code helps someone:
<p:pickList id="formPickList"
value="#{mediaDetail.availableMedia}"
converter="MediaPicklistConverter"
widgetVar="formsPicklistWidget"
var="mediaFiles"
itemLabel="#{mediaFiles.mediaTitle}"
itemValue="#{mediaFiles}" >
<f:facet name="sourceCaption">Available Media</f:facet>
<f:facet name="targetCaption">Chosen Media</f:facet>
</p:pickList>
<p:commandButton id="viewStream_btn"
value="Stream chosen media"
icon="fa fa-download"
ajax="true"
action="#{mediaDetail.prepareStreams}"
update=":streamDialogPanel"
oncomplete="PF('streamingDialog').show()"
styleClass="ui-priority-primary"
style="margin-top:5px" >
<p:ajax process="formPickList" />
</p:commandButton>
The dialog is at the top of the XHTML outside this form and it has a form of its own embedded in the dialog along with a datatable which holds additional commands for streaming the media that all needed to be primed and ready to go when the dialog is presented. You can use this same technique to do things like download customized documents that need to be prepared before they are streamed to the user's computer via fileDownload buttons in the dialog box as well.
As I said, this is a more complicated example, but it hits all the high points of your problem and mine. When the command button is clicked, the result is to first insure the backing bean is updated with the results of the pickList, then tell the backing bean to prepare streams for the user based on their selections in the pick list, then update the controls in the dynamic dialog with an update, then show the dialog box ready for the user to start streaming their content.
The trick to it was to use BalusC's order of events for the main commandButton and then to add the <p:ajax process="formPickList" />
bit to ensure it was executed first - because nothing happens correctly unless the pickList updated the backing bean first (something that was not happening for me before I added it). So, yea, that commandButton rocks because you can affect previous, pending and current components as well as the backing beans - but the timing to interrelate all of them is not easy to get a handle on sometimes.
Happy coding!
Try adding an event listener for clicks:
document.getElementById('button').addEventListener("click", function() {
alert("You clicked me");
}?);?
Using addEventListener
is probably a better idea then setting onclick
- onclick
can easily be overwritten by another piece of code.
You can use a variable to store whether or not the button has been clicked before:
var clicked = false
document.getElementById('button').addEventListener("click", function() {
clicked = true
}?);?
I've tryied all answers of this topic, but just this below worked fine on my project.

at agm-map

When the normType
is NORM_MINMAX
, cv::normalize
normalizes _src
in such a way that the min value of dst
is alpha
and max value of dst
is beta
. cv::normalize
does its magic using only scales and shifts (i.e. adding constants and multiplying by constants).
CV_8UC1
says how many channels dst
has.
The documentation here is pretty clear: http://docs.opencv.org/modules/core/doc/operations_on_arrays.html#normalize

create a pair of client / server, so that after the execution, client server sends the correct time and date. Then, the client asks the server pm GMT and the server sends back the answer right.
Yes, they are all the same.
We can review the interpreted machine code to confirm that that they're all doing the exact same thing.
import dis
def f1():
print "Hello World"
return None
def f2():
print "Hello World"
return
def f3():
print "Hello World"
dis.dis(f1)
4 0 LOAD_CONST 1 ('Hello World')
3 PRINT_ITEM
4 PRINT_NEWLINE
5 5 LOAD_CONST 0 (None)
8 RETURN_VALUE
dis.dis(f2)
9 0 LOAD_CONST 1 ('Hello World')
3 PRINT_ITEM
4 PRINT_NEWLINE
10 5 LOAD_CONST 0 (None)
8 RETURN_VALUE
dis.dis(f3)
14 0 LOAD_CONST 1 ('Hello World')
3 PRINT_ITEM
4 PRINT_NEWLINE
5 LOAD_CONST 0 (None)
8 RETURN_VALUE
The previous answers show 3 approaches
Let me show #4 approach "By using "cbind" and "rename" that works for my case
df <- data.frame(b = c(1, 1, 1), c = c(2, 2, 2), d = c(3, 3, 3))
new_column = c(0, 0, 0)
df <- cbind(new_column, df)
colnames(df)[1] <- "a"
Create a group object and call methods like below example:
grp = df.groupby(['col1', 'col2', 'col3'])
grp.max()
grp.mean()
grp.describe()
char ch = 't';
char chArray[2];
sprintf(chArray, "%c", ch);
char chOutput[10]="tes";
strcat(chOutput, chArray);
cout<<chOutput;
OUTPUT:
test
Other answers are correct to suggest Sort
, but they seem to have missed the fact that the storage location is typed as IList<string
. Sort
is not part of the interface.
If you know that ListaServizi
will always contain a List<string>
, you can either change its declared type, or use a cast. If you're not sure, you can test the type:
if (typeof(List<string>).IsAssignableFrom(ListaServizi.GetType()))
((List<string>)ListaServizi).Sort();
else
{
//... some other solution; there are a few to choose from.
}
Perhaps more idiomatic:
List<string> typeCheck = ListaServizi as List<string>;
if (typeCheck != null)
typeCheck.Sort();
else
{
//... some other solution; there are a few to choose from.
}
If you know that ListaServizi
will sometimes hold a different implementation of IList<string>
, leave a comment, and I'll add a suggestion or two for sorting it.
It's simple. Wrap the image and the "appear on hover" description in a div with the same dimensions of the image. Then, with some CSS, order the description to appear while hovering that div.

A nice fiddle: https://jsfiddle.net/govdqd8y/
As DimtryB mentioned, by default the keystore is under the user directory. But if you are trying to update the cacerts
file, so that the JVM can pick the keys, then you will have to update the cacerts
file under jre/lib/security
. You can also view the keys by executing the command keytool -list -keystore cacerts
to see if your certificate is added.
Ok, here in 2020 on 9.1.12. I don't understand why exactly this process is so difficult. I followed almost every post above and none of them worked for me.
What DID work was this: Totally removing the favicon reference in index.html. It's totally counter intuitive but it works. You DON'T need to put it in the assets
folder. I tried all of that but unfortunately none of those suggestions worked.
index.html
<!-- <link rel="icon" type="image/x-icon" href="favicon.ico"> DELETE THIS -->
angular.json
"assets": [
"src/favicon.ico",
"src/assets"
],
and when I run ng build --prod
, the favicon is there. Displays on my live server too.
To accessing member functions or variables from one scope to another scope (In your case one method to another method we need to refer method or variable with class object. and you can do it by referring with self keyword which refer as class object.
class YourClass():
def your_function(self, *args):
self.callable_function(param) # if you need to pass any parameter
def callable_function(self, *params):
print('Your param:', param)
I might suggest this, as a more gracefully degrading solution, using preventDefault
:
$('a').click(function(e) {
e.preventDefault(); //stop the browser from following
window.location.href = 'uploads/file.doc';
});
<a href="no-script.html">Download now!</a>
Even if there's no Javascript, at least this way the user will get some feedback.
In my case, the issue was not about binding redirects or missing/mismatched Microsoft.AspNet.Razor package/dlls, so the above solutions didn't work.
The issue, in my non-web project, was that RazorEngine+Microsoft.AspNet.Razor were installed in a different project (Project A) than the calling assembly/start-up project (Project B). Because there's no explicit reference to Razor, the System.Web.Razor did NOT get copied to /bin in a Release build.
The solution was to Install RazorEngine+Microsoft.AspNet.Razor in the application entry point (Project B, ConsoleApplication in my case), then the System.Web.Razor gets copied to /bin and everyone's happy.
The ol, ul lists will work if you want you can also use a table with border: none in the css.
All the other solutions require specifying a release/version number which obviously breaks automation.
This solution- currently tested and known to work with Github API v3- however can be used programmatically to grab the LATEST release without specifying any tag or release number and un-TARs the binary to an arbitrary name you specify in switch --one-top-level="pi-ap"
. Just swap-out user f1linux and repo pi-ap in below example with your own details and Bob's your uncle:
curl -L https://api.github.com/repos/f1linux/pi-ap/tarball | tar xzvf - --one-top-level="pi-ap" --strip-components 1
I had a similar issue, in that I only wanted return elements that were visible in a page object. I found that I'm able to use the css :not
. In the case of this issue, this should do you...
expect($('i.icon-spinner:not(.ng-hide)').isDisplayed()).toBeTruthy();
In the context of a page object, you can get ONLY those elements that are visible in this way as well. Eg. given a page with multiple items, where only some are visible, you can use:
this.visibileIcons = $$('i.icon:not(.ng-hide)');
This will return you all visible i.icon

Although the question specifically describes installing 2.6, I would like to add some importants points to the excellent answers above in case someone comes across this. For the record, my case was that I was trying to install 2.7 on an ubuntu 10.04 box.
First, my motivation towards the methods described in all the answers here is that installing Python from deadsnake's ppa's has been a total failure. So building a local Python is the way to go.
Having tried so, I thought relying to the default installation of pip (with sudo apt-get install pip
) would be adequate. This unfortunately is wrong. It turned out that I was getting all shorts of nasty issues and eventually not being able to create a virtualenv.
Therefore, I highly recommend to install pip locally with wget https://raw.github.com/pypa/pip/master/contrib/get-pip.py && python get-pip.py --user
. This related question gave me this hint.
Now if this doesn't work, make sure that libssl-dev
for Ubuntu or openssl-dev
for CentOS is installed. Install them with apt-get
or yum
and then re-build Python (no need to remove anything if already installed, do so on top). get-pip
complains about that, you can check so by running import ssl
on a py shell.
Last, don't forget to declare .local/bin
and local python to path, check with which pip
and which python
.
Swift:
Map.setRegion(MKCoordinateRegion(center: locValue, latitudinalMeters: 200, longitudinalMeters: 200), animated: true)
locValue is your coordinate.
Let's consider the following simplified example:
public class Example {
public static void main(String[] args) {
int[] factors = {1, 2, 3};
ArrayList<Integer> f = new ArrayList(Arrays.asList(factors));
System.out.println(f);
}
}
At the println line this prints something like "[[I@190d11]" which means that you have actually constructed an ArrayList that contains int arrays.
Your IDE and compiler should warn about unchecked assignments in that code. You should always use new ArrayList<Integer>()
or new ArrayList<>()
instead of new ArrayList()
. If you had used it, there would have been a compile error because of trying to pass List<int[]>
to the constructor.
There is no autoboxing from int[]
to Integer[]
, and anyways autoboxing is only syntactic sugar in the compiler, so in this case you need to do the array copy manually:
public static int getTheNumber(int[] factors) {
List<Integer> f = new ArrayList<Integer>();
for (int factor : factors) {
f.add(factor); // after autoboxing the same as: f.add(Integer.valueOf(factor));
}
Collections.sort(f);
return f.get(0) * f.get(f.size() - 1);
}
I was looking for the onClick option to set the title and body of the modal based on the item in a list. T145's answer helped a lot, so I wanted to share how I used it.
Make sure the tag containing the JavaScript function is of type text/javascript to avoid conflicts:
<script type="text/javascript"> function showMyModalSetTitle(myTitle, myBodyHtml) {
/*
* '#myModayTitle' and '#myModalBody' refer to the 'id' of the HTML tags in
* the modal HTML code that hold the title and body respectively. These id's
* can be named anything, just make sure they are added as necessary.
*
*/
$('#myModalTitle').html(myTitle);
$('#myModalBody').html(myBodyHtml);
$('#myModal').modal('show');
}</script>
This function can now be called in the onClick method from inside an element such as a button:
<button type="button" onClick="javascript:showMyModalSetTitle('Some Title', 'Some body txt')"> Click Me! </button>
Quoted from https://developer.mozilla.org/en/DOM/element.click
The click method is intended to be used with INPUT elements of type button, checkbox, radio, reset or submit. Gecko does not implement the click method on other elements that might be expected to respond to mouse–clicks such as links (A elements), nor will it necessarily fire the click event of other elements.
Non–Gecko DOMs may behave differently.
Unfortunately it sounds like you have already discovered the best solution to your problem.
As a side note, I agree that your solution seems less than ideal, but if you encapsulate the functionality inside a method (much like JQuery would do) it is not so bad.
Math.round(number*100.0)/100.0;
<style>
.dotted {border: 1px dotted #ff0000; border-style: none none dotted; color: #fff; background-color: #fff; }
</style>
<hr class='dotted' />
Check that doPost()
method of servlet is called from the jsp form and remove conn.commit
.
You need to convert those to actual dates instead of strings, try this:
SELECT *
FROM <TABLENAME>
WHERE start_date BETWEEN TO_DATE('2010-01-15','YYYY-MM-DD') AND TO_DATE('2010-01-17', 'YYYY-MM-DD');
Edited to deal with format as specified:
SELECT *
FROM <TABLENAME>
WHERE start_date BETWEEN TO_DATE('15-JAN-10','DD-MON-YY') AND TO_DATE('17-JAN-10','DD-MON-YY');
Your string is invalid, but assuming it was valid, you'd have to do:
var finalData = str.replace(/\\/g, "");
When you want to replace all the occurences with .replace
, the first parameter must be a regex, if you supply a string, only the first occurrence will be replaced, that's why your replace wouldn't work.

For some reason no one has mentioned the fact that the bashrc needs to be re-sourced after editing. You can either log out and log back in (like mentioned above) but you can also use the commands: source ~/.bashrc
or . ~/.bashrc
.
If you mean getting a powered NFC device to pretend to be a passive one (eg a tag).. not sure how well it works but the android app NFCClassic purports to record tag contents and then allow the tag to be activated and appear to be the copied tag to NFC readers. Creates a library of recorded tags.
You can use GCD (in the example with a 10 second delay):
let triggerTime = (Int64(NSEC_PER_SEC) * 10)
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, triggerTime), dispatch_get_main_queue(), { () -> Void in
self.functionToCall()
})
DispatchQueue.main.asyncAfter(deadline: .now() + 10.0, execute: {
self.functionToCall()
})
DispatchQueue.main.asyncAfter(deadline: .now() + 10.0) {
//call any function
}
Go to your program.cs file add UseUrs method to set your url, make sure you don't use a reserved url or port
public class Program
{
public static void Main(string[] args)
{
BuildWebHost(args).Run();
}
public static IWebHost BuildWebHost(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
// params string[] urls
.UseUrls(urls: "http://localhost:10000")
.Build();
}
For z-index to work, you also need to give it a position:
header {
width: 100%;
height: 100px;
background: url(../img/top.png) repeat-x;
z-index: 110;
position: relative;
}
Unfortunately - it could be many things - and lots of app servers and other java 'wrappers' are prone to play with properties and their 'own' take on keychains and what not. So it may be looking at something totally different.
Short of truss-ing - I'd try:
java -Djavax.net.debug=all -Djavax.net.ssl.trustStore=trustStore ...
to see if that helps. Instead of 'all' one can also set it to 'ssl', key manager and trust manager - which may help in your case. Setting it to 'help' will list something like below on most platforms.
Regardless - do make sure you fully understand the difference between the keystore (in which you have the private key and cert you prove your own identity with) and the trust store (which determines who you trust) - and the fact that your own identity also has a 'chain' of trust to the root - which is separate from any chain to a root you need to figure out 'who' you trust.
all turn on all debugging
ssl turn on ssl debugging
The following can be used with ssl:
record enable per-record tracing
handshake print each handshake message
keygen print key generation data
session print session activity
defaultctx print default SSL initialization
sslctx print SSLContext tracing
sessioncache print session cache tracing
keymanager print key manager tracing
trustmanager print trust manager tracing
pluggability print pluggability tracing
handshake debugging can be widened with:
data hex dump of each handshake message
verbose verbose handshake message printing
record debugging can be widened with:
plaintext hex dump of record plaintext
packet print raw SSL/TLS packets

If you look at the down arrow in environment tab. The attached file can appear multiple times. You may need to highlight and run detach(filename)
several times until all cases are gone then attach(newfilename)
should have no output message.
I was able to fix the error using the following query:
mongoimport --db dbName --collection collectionName --file fileName.json --jsonArray
Hopefully this is helpful to someone.
This question has been answered already several times, I'll short summary for each of them, an example and insights as of September 2019:
Example: <h1>
tag inside <section>
by default Google Chrome will make smaller than the "expected" size of <h1>
tag. Microsoft Edge on the other hand is making the "expected" size of <h1>
tag. Normalize.css will make it consistent.
Current status: the npm repository shows that normalize.css package has currently more than 500k downloads per week. GitHub stars in the project of the repository are more than 36k.
Example: it would do something like that below:
html, body, div, span, ..., audio, video {
margin: 0;
padding: 0;
border: 0;
font-size: 100%;
font: inherit;
vertical-align: baseline;
}
Current status: it's much less popular than Normalize.css, the reset-css package shows it's something around 26k downloads per week. GitHub stars are only 200, as it can be noticed from the project's repository.
From Object Explorer in SQL Server Management Studio, find your database and expand the node (click on the + sign beside your database). The first item from that expanded tree is Database Diagrams. Right-click on that and you'll see various tasks including creating a new database diagram. If you've never created one before, it'll ask if you want to install the components for creating diagrams. Click yes then proceed.
Try running git status
on the file. It will print an error if it's not tracked by git
PS$> git status foo.txt
error: pathspec 'foo.txt' did not match any file(s) known to git.
you should use the break statement
usually it's use this way
$i = 0;
foreach($data as $key => $row){
if(++$i > 2) break;
}
on the same fashion the continue statement exists if you need to skip some items.
Consider using a higher dimensional datastructure (a Panel), rather than storing an array in your column:
In [11]: p = pd.Panel({'df': df, 'csc': csc})
In [12]: p.df
Out[12]:
0 1 2
0 1 2 3
1 4 5 6
2 7 8 9
In [13]: p.csc
Out[13]:
0 1 2
0 0 1 0
1 0 0 1
2 1 0 0
Look at cross-sections etc, etc, etc.
In [14]: p.xs(0)
Out[14]:
csc df
0 0 1
1 1 2
2 0 3
Try this:
Select
Id,
Salt,
Password,
BannedEndDate,
(Select Count(*)
From LoginFails
Where username = '" + LoginModel.Username + "' And IP = '" + Request.ServerVariables["REMOTE_ADDR"] + "')
From Users
Where username = '" + LoginModel.Username + "'
And I recommend you strongly to use parameters in your query to avoid security risks with sql injection attacks!
Hope that helps!
>>> from netaddr import all_matching_cidrs
>>> all_matching_cidrs("212.11.70.34", ["192.168.0.0/24","212.11.64.0/19"] )
[IPNetwork('212.11.64.0/19')]
Here is the usage for this method:
>>> help(all_matching_cidrs)
Help on function all_matching_cidrs in module netaddr.ip:
all_matching_cidrs(ip, cidrs)
Matches an IP address or subnet against a given sequence of IP addresses and subnets.
@param ip: a single IP address or subnet.
@param cidrs: a sequence of IP addresses and/or subnets.
@return: all matching IPAddress and/or IPNetwork objects from the provided
sequence, an empty list if there was no match.
Basically you provide an ip address as the first argument and a list of cidrs as the second argument. A list of hits are returned.
