Sorry guys, but selecting from all_tab_privs_recd where grantee = 'your user' will not give any output except public grants and current user grants if you run the select from a different (let us say, SYS) user. As documentation says,
ALL_TAB_PRIVS_RECD describes the following types of grants:
Object grants for which the current user is the grantee Object grants for which an enabled role or PUBLIC is the grantee
So, if you're a DBA and want to list all object grants for a particular (not SYS itself) user, you can't use that system view.
In this case, you must perform a more complex query. Here is one taken (traced) from TOAD to select all object grants for a particular user:
select tpm.name privilege,
decode(mod(oa.option$,2), 1, 'YES', 'NO') grantable,
ue.name grantee,
ur.name grantor,
u.name owner,
decode(o.TYPE#, 0, 'NEXT OBJECT', 1, 'INDEX', 2, 'TABLE', 3, 'CLUSTER',
4, 'VIEW', 5, 'SYNONYM', 6, 'SEQUENCE',
7, 'PROCEDURE', 8, 'FUNCTION', 9, 'PACKAGE',
11, 'PACKAGE BODY', 12, 'TRIGGER',

and oa.grantee# = ue.user#
and oa.col# is null
and oa.privilege# = tpm.privilege
and u.user# = o.owner#
and o.TYPE# in (2, 4, 6, 9, 7, 8, 42, 23, 22, 13, 33, 32, 66, 67, 74, 57)
and ue.name = 'your user'
and bitand (o.flags, 128) = 0
union all -- column level grants
select tpm.name privilege,
decode(mod(oa.option$,2), 1, 'YES', 'NO') grantable,
ue.name grantee,
ur.name grantor,
u.name owner,
decode(o.TYPE#, 2, 'TABLE', 4, 'VIEW', 42, 'MATERIALIZED VIEW') object_type,
o.name object_name,
c.name column_name
from sys.objauth$ oa, sys.obj$ o, sys.user$ u, sys.user$ ur, sys.user$ ue,
sys.col$ c, table_privilege_map tpm
where oa.obj# = o.obj#
and oa.grantor# = ur.user#
and oa.grantee# = ue.user#
and oa.obj# = c.obj#
and oa.col# = c.col#
and bitand(c.property, 32) = 0 /* not hidden column */
and oa.col# is not null
and oa.privilege# = tpm.privilege
and u.user# = o.owner#
and o.TYPE# in (2, 4, 42)
and ue.name = 'your user'
and bitand (o.flags, 128) = 0;
This will list all object grants (including column grants) for your (specified) user. If you don't want column level grants then delete all part of the select beginning with 'union' clause.
UPD: Studying the documentation I found another view that lists all grants in much simpler way:
select * from DBA_TAB_PRIVS where grantee = 'your user';
Bear in mind that there's no DBA_TAB_PRIVS_RECD view in Oracle.

Include js files of datepicker and language (locales)
'resource/bower_components/bootstrap-datepicker/dist/js/bootstrap-datepicker.min.js',
'resource/bower_components/bootstrap-datepicker/dist/locales/bootstrap-datepicker.sv.min.js',
In the options of the datepicker, set the language as below:
$('.datepicker').datepicker({'language' : 'sv'});
In order to match a digit, you can use [0-9]
.
So you could use 5[0-9][0-9][0-9][0-9][0-9][0-9]
and [0-9][0-9][0-9][0-9]7[0-9][0-9][0-9]
. I do this a lot for zip codes.
If you can't find an existing solution it's pretty easy to build a basic one in Java. I just wrote one for a client and it took only a couple hours including researching tools.
Apache POI will read the Excel binary. http://poi.apache.org/
JSONObject will build the JSON
After that it's just a matter of iterating through the rows in the Excel data and building a JSON structure. Here's some pseudo code for the basic usage.
FileInputStream inp = new FileInputStream( file );
Workbook workbook = WorkbookFactory.create( inp );
// Get the first Sheet.
Sheet sheet = workbook.getSheetAt( 0 );
// Start constructing JSON.
JSONObject json = new JSONObject();
// Iterate through the rows.
JSONArray rows = new JSONArray();
for ( Iterator<Row> rowsIT = sheet.rowIterator(); rowsIT.hasNext(); )
{
Row row = rowsIT.next();
JSONObject jRow = new JSONObject();
// Iterate through the cells.
JSONArray cells = new JSONArray();
for ( Iterator<Cell> cellsIT = row.cellIterator(); cellsIT.hasNext(); )
{
Cell cell = cellsIT.next();
cells.put( cell.getStringCellValue() );
}
jRow.put( "cell", cells );
rows.put( jRow );
}
// Create the JSON.
json.put( "rows", rows );
// Get the JSON text.
return json.toString();
Just stack two bootstrap tables; one for columns, the other for content. No plugins, just pure bootstrap (and that ain't no bs, haha!)
<table id="tableHeader" class="table" style="table-layout:fixed">
<thead>
<tr>
<th>Col1</th>
...
</tr>
</thead>
</table>
<div style="overflow-y:auto;">
<table id="tableData" class="table table-condensed" style="table-layout:fixed">
<tbody>
<tr>
<td>data</td>
...
</tr>
</tbody>
</table>
</div>
The content table div needs overflow-y:auto
, for vertical scroll bars. Had to use table-layout:fixed
, otherwise, columns did not line up. Also, had to put the whole thing inside a bootstrap panel to eliminate space between the tables.
Have not tested with custom column widths, but provided you keep the widths consistent between the tables, it should work.
// ADD THIS JS FUNCTION TO MATCH UP COL WIDTHS
$(function () {
//copy width of header cells to match width of cells with data
//so they line up properly
var tdHeader = document.getElementById("tableHeader").rows[0].cells;
var tdData = document.getElementById("tableData").rows[0].cells;
for (var i = 0; i < tdData.length; i++)
tdHeader[i].style.width = tdData[i].offsetWidth + 'px';
});
You can write like this.
import java.util.Scanner;
class BigNoArray{
public static void main(String[] args){

int n=sc.nextInt();

for(int i=0;i<ar.length;i++){

int fbig=ar[0];
int sbig=ar[1];
int tbig=ar[3];
for(int i=1;i<ar.length;i++){
if(fbig<ar[i]){

}
}
System.out.println("first big number is "+fbig);

Modules Preconditions:
The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (
precondition="managedHandler"
) only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" preCondition="managedHandler" />
If you remove the attribute
precondition="managedHandler"
, Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See "How to Take Advantage of IIS Integrated Pipeline" for an example of enabling ASP.NET modules to run for all content.You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the "
managedHandler
" precondition.To enable all managed modules to run for all requests without configuring each module entry to remove the "
managedHandler
" precondition, use therunAllManagedModulesForAllRequests
property in the<modules>
section:<modules runAllManagedModulesForAllRequests="true" />
When you use this property, the "
managedHandler
" precondition has no effect and all managed modules run for all requests.

Floated elements don’t take up any vertical space in their containing element.
All of your elements inside #albumhold
are floated, apart from #albumhead
, which doesn’t look like it’d take up much space.
However, if you add overflow: hidden;
to #albumhold
(or some other CSS to clear floats inside it), it will expand its height to encompass its floated children.
Try to get your archive using wget
, I had the same issue when I was downloading archive through browser. Than I just copy archive link and in terminal use the command:
wget http://PATH_TO_ARCHIVE
The '\r' stands for "Carriage Return" - it's a holdover from the days of typewriters and really old printers. The best example is in Windows and other DOSsy OSes, where a newline is given as "\r\n". These are the instructions sent to an old printer to start a new line: first move the print head back to the beginning, then go down one.
Different OSes will use other newline sequences. Linux and OSX just use '\n'. Older Mac OSes just use '\r'. Wikipedia has a more complete list, but those are the important ones.
Hope this helps!
PS: As for why you get that weird output... Perhaps the console is moving the "cursor" back to the beginning of the line, and then overwriting the first bit with spaces or summat.
If you're using ng-view
in your Angular app you can listen for the $viewContentLoaded
event and push a tracking event to Google Analytics.
Assuming you've set up your tracking code in your main index.html file with a name of var _gaq
and MyCtrl is what you've defined in the ng-controller
directive.
function MyCtrl($scope, $location, $window) {
$scope.$on('$viewContentLoaded', function(event) {
$window._gaq.push(['_trackPageView', $location.url()]);
});
}
UPDATE: for new version of google-analytics use this one
function MyCtrl($scope, $location, $window) {
$scope.$on('$viewContentLoaded', function(event) {
$window.ga('send', 'pageview', { page: $location.url() });
});
}
I had the exact same issue. If you are using a relative path os.path.dirname(path) will only return the relative path. os.path.realpath does the trick:
>>> import os
>>> f = open('file.txt')
>>> os.path.realpath(f.name)
The try-with-resources
Statement.
The try-with-resources statement
is a try
statement that declares one or more resources. A resource
is an object that must be closed after the program is finished with it. The try-with-resources statement
ensures that each resource is closed at the end of the statement. Any object that implements java.lang.AutoCloseable
, which includes all objects which implement java.io.Closeable
, can be used as a resource.
The following example reads the first line from a file. It uses an instance of BufferedReader
to read data from the file. BufferedReader
is a resource that must be closed after the program is finished with it:
static String readFirstLineFromFile(String path) throws IOException {
try (BufferedReader br =
new BufferedReader(new FileReader(path))) {
return br.readLine();
}
}
In this example, the resource declared in the try-with-resources statement is a BufferedReader. The declaration statement appears within parentheses immediately after the try keyword. The class BufferedReader
, in Java SE 7 and later, implements the interface java.lang.AutoCloseable
. Because the BufferedReader
instance is declared in a try-with-resource statement, it will be closed regardless of whether the try statement completes normally or abruptly (as a result of the method BufferedReader.readLine
throwing an IOException
).
Prior to Java SE 7, you can use a finally
block to ensure that a resource is closed regardless of whether the try statement completes normally or abruptly. The following example uses a finally
block instead of a try-with-resources
statement:
static String readFirstLineFromFileWithFinallyBlock(String path)
throws IOException {
BufferedReader br = new BufferedReader(new FileReader(path));
try {
return br.readLine();
} finally {
if (br != null) br.close();
}
}
Please refer to the docs.
Well, the <head>
tag has nothing to do with the <header>
tag. In the head
comes all the metadata and stuff, while the header
is just a layout component.
And layout comes into body
. So I disagree with you.
If you're in a scenario where you are looping while a resource is unavaliable or something similar that throws an exception, you could use something like
import time
while True:
try:
f = open('some/path', 'r')
except IOError:
print('File could not be read. Retrying in 5 seconds')
time.sleep(5)
else:
break
By default Mocha will read a file named test/mocha.opts
that can contain command line arguments. So you could create such a file that contains:
--timeout 5000
Whenever you run Mocha at the command line, it will read this file and set a timeout of 5 seconds by default.
Another way which may be better depending on your situation is to set it like this in a top level describe
call in your test file:
describe("something", function () {
this.timeout(5000);
// tests...
});
This would allow you to set a timeout only on a per-file basis.
You could use both methods if you want a global default of 5000 but set something different for some files.
Note that you cannot generally use an arrow function if you are going to call this.timeout
(or access any other member of this
that Mocha sets for you). For instance, this will usually not work:
describe("something", () => {
this.timeout(5000); //will not work
// tests...
});
This is because an arrow function takes this
from the scope the function appears in. Mocha will call the function with a good value for this
but that value is not passed inside the arrow function. The documentation for Mocha says on this topic:
Passing arrow functions (“lambdas”) to Mocha is discouraged. Due to the lexical binding of this, such functions are unable to access the Mocha context.

Declaring variables inside or outside of a loop, It's the result of JVM specifications But in the name of best coding practice it is recommended to declare the variable in the smallest possible scope (in this example it is inside the loop, as this is the only place where the variable is used). Declaring objects in the smallest scope improve readability. The scope of local variables should always be the smallest possible. In your example I presume str is not used outside of the while loop, otherwise you would not be asking the question, because declaring it inside the while loop would not be an option, since it would not compile.
Does it make a difference if I declare variables inside or outside a , Does it make a difference if I declare variables inside or outside a loop in Java? Is this for(int i = 0; i < 1000; i++) { int At the level of the individual variable there is no significant difference in effeciency, but if you had a function with 1000 loops and 1000 variables (never mind the bad style implied) there could be systemic differences because all the lives of all the variables would be the same instead of overlapped.
Declaring Loop Control Variables Inside the for Loop, When you declare a variable inside a for loop, there is one important point to remember: the scope of that variable ends when the for statement does. (That is, the scope of the variable is limited to the for loop.) This Java Example shows how to declare multiple variables in Java For loop using declaration block.
use Json & jQuery. It's way easier than oldschool javascript
function savedata1() {
var obj = $('#myTable tbody tr').map(function() {
var $row = $(this);
var t1 = $row.find(':nth-child(1)').text();
var t2 = $row.find(':nth-child(2)').text();
var t3 = $row.find(':nth-child(3)').text();
return {
td_1: $row.find(':nth-child(1)').text(),
td_2: $row.find(':nth-child(2)').text(),
td_3: $row.find(':nth-child(3)').text()
};
}).get();
Use output buffering:
<?php
ob_start();
var_dump($someVar);
$result = ob_get_clean();
?>
This is the behavior of ln
if the second arg is a directory. It places a link to the first arg inside it. If you want /etc/nginx
to be the symlink, you should remove that directory first and run that same command.
Added: I found something that should do the trick right away, but the rest of the code below also offers an alternative.
Use the subplots_adjust()
function to move the bottom of the subplot up:
fig.subplots_adjust(bottom=0.2) # <-- Change the 0.02 to work for your plot.
Then play with the offset in the legend bbox_to_anchor
part of the legend command, to get the legend box where you want it. Some combination of setting the figsize
and using the subplots_adjust(bottom=...)
should produce a quality plot for you.
Alternative: I simply changed the line:
fig = plt.figure(1)
to:
fig = plt.figure(num=1, figsize=(13, 13), dpi=80, facecolor='w', edgecolor='k')
and changed
lgd = ax.legend(loc=9, bbox_to_anchor=(0.5,0))
to
lgd = ax.legend(loc=9, bbox_to_anchor=(0.5,-0.02))
and it shows up fine on my screen (a 24-inch CRT monitor).
Here figsize=(M,N)
sets the figure window to be M inches by N inches. Just play with this until it looks right for you. Convert it to a more scalable image format and use GIMP to edit if necessary, or just crop with the LaTeX viewport
option when including graphics.
There are 3 different methods depending on what I is my requirement and which version I am using.
Here are the methods..
1) Using Convert
DECLARE @DateTime DATETIME = GETDATE();
--Using Convert
SELECT
CONVERT(NVARCHAR, @DateTime,120) AS 'myDateTime'
,CONVERT(NVARCHAR(10), @DateTime, 120) AS 'myDate'
,RIGHT(CONVERT(NVARCHAR, @DateTime, 120),8) AS 'myTime'
2) Using Cast (SQL Server 2008 and beyond)
SELECT
CAST(@DateTime AS DATETIME2) AS 'myDateTime'
,CAST(@DateTime AS DATETIME2(3)) AS 'myDateTimeWithPrecision'
,CAST(@DateTime AS DATE) AS 'myDate'
,CAST(@DateTime AS TIME) AS 'myTime'
,CAST(@DateTime AS TIME(3)) AS 'myTimeWithPrecision'
3) Using Fixed-length character data type
DECLARE @myDateTime NVARCHAR(20) = CONVERT(NVARCHAR, @DateTime, 120);
DECLARE @myDate NVARCHAR(10) = CONVERT(NVARCHAR, @DateTime, 120);
SELECT
@myDateTime AS 'myDateTime'
,@myDate AS 'myDate'
All of the answers are good but not complete. Use this.

This gets a little complicated. These objects are custom classes or structs, and looking inside them is not as easy on Xcode as in other development environments.
If I were you, I'd NSLog the values you want to see, with some description.
i.e:
NSLog(@"Description of object & time: %i", indexPath.row);

To give an extra solution to the above 'This app is incompatible with your...' problem, let me share my solution for a different problem cause. I tried installing an app on a low-end Samsung Galaxy Y (GT-S6350) device and got this error from the Play store. To test various AndroidManifest configurations, I created an account and followed the routine as described in https://stackoverflow.com/a/5449397/372838 until my device showed up in the supported device list.
It turned out that a lot of devices become incompatible when you use the Camera permission:
<uses-permission android:name="android.permission.CAMERA" />
When I removed that specific permission, the application was available for 1180 devices instead of 870. Hope it will help someone

It's torture. Instead of including a generic conf file, they make you hit return 9000 times to generate one.
I would change your binding to be:
<button type="button" value="click me" onclick="check_me" />
I would then change your check_me()
function declaration to be:
function check_me() {
//event.preventDefault();
var hello = document.myForm.username.value;
var err = '';
if(hello == '' || hello == null) {
err = 'User name required';
}
if(err != '') {
alert(err);
$('username').focus();
event.preventDefault();
} else {
return true; }
}
Probably the shortest version:
[System.Collections.ArrayList]$someArray
It is also faster because it does not call relatively expensive New-Object
.
If you change your html code a bit - remove the ids
<ul id='myid'>
<li>First</li>
<li>Second</li>
<li>Third</li>
<li>Fourth</li>
<li>Fifth</li>
</ul>
Then the jquery code you want is...
$("#myid li").click(function() {
alert($(this).prevAll().length+1);
});?
You don't need to place any ids, just keep on adding li items.

Date beginDate = dateFormat.parse("2013-11-29");
Date endDate = dateFormat.parse("2013-12-4");
Calendar beginCalendar = Calendar.getInstance();
beginCalendar.setTime(beginDate);
Calendar endCalendar = Calendar.getInstance();
endCalendar.setTime(endDate);
There is simple way to implement it. We can use Calendar.add method with loop. The minus days between beginDate and endDate, and the implemented code as below,
int minusDays = 0;
while (true) {
minusDays++;
// Day increasing by 1
beginCalendar.add(Calendar.DAY_OF_MONTH, 1);
if (dateFormat.format(beginCalendar.getTime()).
equals(dateFormat.format(endCalendar).getTime())) {
break;
}
}
System.out.println("The subtraction between two days is " + (minusDays + 1));**
This answer is for XAMPP on Ubuntu.
The manual for installation and download is on (site official)
http://www.apachefriends.org/it/xampp-linux.html
After to start XAMPP simply call this command:
sudo /opt/lampp/lampp start
You should now see something like this on your screen:
Starting XAMPP 1.8.1...
LAMPP: Starting Apache...
LAMPP: Starting MySQL...
LAMPP started.
If you have this
Starting XAMPP for Linux 1.8.1...
XAMPP: Another web server daemon is already running.
XAMPP: Another MySQL daemon is already running.
XAMPP: Starting ProFTPD...
XAMPP for Linux started
. The solution is
sudo /etc/init.d/apache2 stop
sudo /etc/init.d/mysql stop
And the restast with sudo //opt/lampp/lampp restart
You to fix most of the security weaknesses simply call the following command:
/opt/lampp/lampp security
After the change this file
sudo kate //opt/lampp/etc/extra/httpd-xampp.conf
Find and replace on
#
# New XAMPP security concept

Besides using Android Studio, you can also take a screenshot with adb which is faster.
adb shell screencap -p /sdcard/screen.png
adb pull /sdcard/screen.png
adb shell rm /sdcard/screen.png
Shorter one line alternative in Unix/OSX
adb shell screencap -p | perl -pe 's/\x0D\x0A/\x0A/g' > screen.png

gacutil comes with Visual Studio, not with VSTS. It is part of Windows SDK and can be download separately at http://www.microsoft.com/downloads/details.aspx?FamilyId=F26B1AA4-741A-433A-9BE5-FA919850BDBF&displaylang=en . This installation will have gacutil.exe
included. But first check it here
C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin
you might have it installed.
As @devi mentioned
If you decide to grab gacutil files from existing installation, note that from .NET 4.0 is three files: gacutil.exe gacutil.exe.config and 1033/gacutlrc.dll
General Question:
Stream does not store any elements.
So iterating elements in the reverse order is not possible without storing the elements in some intermediate collection.
Stream.of("1", "2", "20", "3")
.collect(Collectors.toCollection(ArrayDeque::new)) // or LinkedList
.descendingIterator()
.forEachRemaining(System.out::println);
Update: Changed LinkedList to ArrayDeque (better) see here for details
Prints:
3
20
2
1
By the way, using sort
method is not correct as it sorts, NOT reverses (assuming stream may have unordered elements)
Specific Question:
I found this simple, easier and intuitive(Copied @Holger comment)
IntStream.iterate(to - 1, i -> i - 1).limit(to - from)
Try PowerPoint ActiveX 2.4. This is an ActiveX component that embeds PowerPoint into an OCX.
Since you are using just Internet Explorer 6 and Internet Explorer 7 you can embed this component into the HTML.

In my case it did not work until I ran the command

that way you can leave the foreign keys inside the create Schema
public function up()
{
//
Schema::create('priorities', function($table) {
$table->increments('id', true);
$table->integer('user_id');
$table->foreign('user_id')->references('id')->on('users');
$table->string('priority_name');
$table->smallInteger('rank');
$table->text('class');
$table->timestamps('timecreated');
});
}
/**

public function down()
{
//
Schema::drop('priorities');
}
Yes, something like this:
SELECT
id,
action_heading,
CASE
WHEN action_type = 'Income' THEN action_amount
ELSE NULL
END AS income_amt,
CASE
WHEN action_type = 'Expense' THEN action_amount
ELSE NULL
END AS expense_amt
FROM tbl_transaction;
As other answers have pointed out, MySQL also has the IF()
function to do this using less verbose syntax. I generally try to avoid this because it is a MySQL-specific extension to SQL that isn't generally supported elsewhere. CASE
is standard SQL and is much more portable across different database engines, and I prefer to write portable queries as much as possible, only using engine-specific extensions when the portable alternative is considerably slower or less convenient.
CentOS 7+ Minimal Secure Solution: (should work with RedHat too)
chcon -Rv --type=mysqld_db_t /YOUR/PATH/
Explanation:
Knowing that you applied the good practice of using secure-file-priv=/YOUR/PATH/
in my.cnf
in order to use load data infile
sql statement, you still see the following:
ERROR 13 (HY000): Can't get stat of '/YOUR/PATH/FILE.EXT' (Errcode: 13 "Permission denied")
That's caused by SELinux Enforcing
mode, it's not secure to change the mode to Permissive
or disable SELinux.
In short,
chcon
change SELinux security context of a file or files/directories in a similar way to how 'chown' or 'chmod' may be used to change the ownership or standard file permissions of a file.
SELinux Enforcing
mode prevents mysqld
from accessing directories with secure-context-type default_t
, hence we need to change the secure-context-type of our path to mysqld_db_t
. To see the current secure-context-type use the command:
ls --directory --scontext /YOUR/PATH/
In case you want to reset/undo the solution, then apply below command:
restorecon -Rv /YOUR/PATH/
The solution I shared is referenced in below links:
https://wiki.centos.org/HowTos/SELinux
https://mariadb.com/kb/en/selinux/
https://linux.die.net/man/8/mysqld_selinux
Why are you sending it through a post if you already have it on the server (PHP) side?
Why not just save the array to s $_SESSION
variable so you can use it when the form gets submitted, that might make it more "secure" since then the client cannot change the variables by editing the source.
It all depends on what you really want to do.
>>> list1 = [1,2,3,4,5,6]
>>> list2 = [3, 5, 7, 9]
>>> list(set(list1).intersection(list2))
[3, 5]
If you need a combination of both version and build num, here's a short way using Swift 3:
let appVersion = Bundle.main.infoDictionary!["CFBundleShortVersionString"]!
let buildNum = Bundle.main.infoDictionary!["CFBundleVersion"]!
let versionInfo = "\(appVersion) (build \(buildNum))"
// versionInfo is now something like "2.3.0 (build 17)"
Add an as! String
to the end of either the appVersion
or buildNum
line to get only that portion as a String
object. No need for that though if you're looking for the full versionInfo
.
I hope this helps!
$(document).ready(function() {
// do needed things
});
This will trigger once the DOM structure is ready.
Static:
Obj.someMethod
Use static
when you want to provide class level access to a method, i.e. where the method should be callable without an instance of the class.
You've staged the deletion so you need to do:
git checkout HEAD cc.properties store/README store/cc.properties
git checkout .
only checks out from the index where the deletion has already been staged.
I haven't done this, so I'm just going to point at the right answer.
C has provisions for functions that take unspecified numbers of operands, using the <stdarg.h>
header. You can define your function as void log_out(const char *fmt, ...);
, and get the va_list
inside the function. Then you can allocate memory and call vsprintf()
with the allocated memory, format, and va_list
.
Alternately, you could use this to write a function analogous to sprintf()
that would allocate memory and return the formatted string, generating it more or less as above. It would be a memory leak, but if you're just logging out it may not matter.
You can use the format
option, as described in the documentation
$("#timePicker").datetimepicker({
format: 'Y-m-d H:i'
});
I got the same trouble, in mobile device with Microsoft's Edge browser. I can solve the problem with: aria-haspopup="true"
. It need to add to the div and the :hover
, :active
, :focus
for the other mobile browsers.
Example html:
<div class="left_bar" aria-haspopup="true">
CSS:
.left_bar:hover, .left_bar:focus, .left_bar:active{
left: 0%;
}
type MyProps = {
workoutType: string | null;
};
Yes, you can always use null
instead of an object. Just be careful because some methods might throw error.
It would be 1.
also null
s would be factored in in the for loop, but you could use
for(Item i : itemList) {
if (i!= null) {
//code here
}
}
when you try to change targetSDKVersion 26 to 25 that time occurred i was found solution of No resource found that matches the given name: attr 'android:keyboardNavigationCluster'. when updating to Support Library 26.0.0
Just Chage This code from Your Build.gradle

I have come accross the above issue. I have solved it as below. Its working fine for me.
Download the 'org.apache.commons.io.jar' file on navigating to [org.apache.commons.io.FileUtils] [ http://www.java2s.com/Code/Jar/o/Downloadorgapachecommonsiojar.htm ]
Extract the downloaded zip file to a specified folder.
Update the project properties by using below navigation Right click on project>Select Properties>Select Java Build Path> Click Libraries tab>Click Add External Class Folder button>Select the folder where zip file is extracted for org.apache.commons.io.FileUtils.zip file.
Now access the File Utils.
Following madlep's answer you can also just copy one directory from another branch with the directory blob.
git checkout other-branch app/**
As to the op's question if you've only changed one file in there this will work fine ^_^
The abstract version can be:
import numpy as np
myList = [10, 20, 30, 40, 50, 60, 70, 80, 90]
myInt = 10
newList = np.divide(myList, myInt)
What is that BasePagerAdapter
? You should use one of the standard pager adapters -- either FragmentPagerAdapter
or FragmentStatePagerAdapter
, depending on whether you want Fragments that are no longer needed by the ViewPager
to either be kept around (the former) or have their state saved (the latter) and re-created if needed again.
Sample code for using ViewPager
can be found here
It is true that the management of fragments in a view pager across activity instances is a little complicated, because the FragmentManager
in the framework takes care of saving the state and restoring any active fragments that the pager has made. All this really means is that the adapter when initializing needs to make sure it re-connects with whatever restored fragments there are. You can look at the code for FragmentPagerAdapter
or FragmentStatePagerAdapter
to see how this is done.
Try this:
Create A Macro with the following thing inside:
Selection.Copy
ActiveCell.Offset(1, 0).Select
ActiveSheet.Paste
ActiveCell.Offset(-1, 1).Select
Selection.Copy
ActiveCell.Offset(1, 0).Select
ActiveSheet.Paste
ActiveCell.Offset(0, -1).Select
That particular macro will copy the current cell (place your cursor in the VOL cell you wish to copy) down one row and then copy the CAP cell also.
This is only a single loop so you can automate copying VOL and CAP of where your current active cell (where your cursor is) to down 1 row.
Just put it inside a For loop statement to do it x number of times. like:
For i = 1 to 100 'Do this 100 times
Selection.Copy
ActiveCell.Offset(1, 0).Select
ActiveSheet.Paste
ActiveCell.Offset(-1, 1).Select
Selection.Copy
ActiveCell.Offset(1, 0).Select
ActiveSheet.Paste
ActiveCell.Offset(0, -1).Select
Next i
This will not only change the max_retries but also enable a backoff strategy which makes requests to all http:// addresses sleep for a period of time before retrying (to a total of 5 times):
import requests
from urllib3.util.retry import Retry
from requests.adapters import HTTPAdapter
s = requests.Session()
retries = Retry(total=5,
backoff_factor=0.1,
status_forcelist=[ 500, 502, 503, 504 ])
s.mount('http://', HTTPAdapter(max_retries=retries))
s.get('http://httpstat.us/500')
As per documentation for Retry
: if the backoff_factor is 0.1, then sleep() will sleep for [0.1s, 0.2s, 0.4s, ...] between retries. It will also force a retry if the status code returned is 500, 502, 503 or 504.
Various other options to Retry
allow for more granular control:
MaxRetryError
, or to return a response with a response code in the 3xx range.NB: raise_on_status is relatively new, and has not made it into a release of urllib3 or requests yet. The raise_on_status keyword argument appears to have made it into the standard library at most in python version 3.6.
To make requests retry on specific HTTP status codes, use status_forcelist. For example, status_forcelist=[503] will retry on status code 503 (service unavailable).
By default, the retry only fires for these conditions:
TimeoutError
HTTPException
raised (from http.client in Python 3 else httplib).
This seems to be low-level HTTP exceptions, like URL or protocol not
formed correctly.SocketError
ProtocolError
Notice that these are all exceptions that prevent a regular HTTP response from being received. If any regular response is generated, no retry is done. Without using the status_forcelist, even a response with status 500 will not be retried.
To make it behave in a manner which is more intuitive for working with a remote API or web server, I would use the above code snippet, which forces retries on statuses 500, 502, 503 and 504, all of which are not uncommon on the web and (possibly) recoverable given a big enough backoff period.
EDITED: Import Retry
class directly from urllib3.
It's easy to create a .NET Windows GUI in C++.
See the following tutorial from MSDN. You can download everything you need (Visual C++ Express) for free.
Of course you tie yourself to .NET, but if you're just playing around or only need a Windows application you'll be fine (most people still have Windows...for now).
consoleargs deserves to be mentioned here. It is very easy to use. Check it out:
from consoleargs import command
@command
def main(url, name=None):
"""
:param url: Remote URL
:param name: File name
"""
print """Downloading url '%r' into file '%r'""" % (url, name)
if __name__ == '__main__':
main()
Now in console:
% python demo.py --help
Usage: demo.py URL [OPTIONS]
URL: Remote URL
Options:
--name -n File name
% python demo.py http://www.google.com/
Downloading url ''http://www.google.com/'' into file 'None'
% python demo.py http://www.google.com/ --name=index.html
Downloading url ''http://www.google.com/'' into file ''index.html''
On a linux system, you can modify terminal behaviour using the stty
command. By default, the terminal will buffer all information until Enter is pressed, before even sending it to the C program.
A quick, dirty, and not-particularly-portable example to change the behaviour from within the program itself:
#include<stdio.h>
#include<stdlib.h>
int main(void){
int c;
/* use system call to make terminal send all keystrokes directly to stdin */
system ("/bin/stty raw");
while((c=getchar())!= '.') {
/* type a period to break out of the loop, since CTRL-D won't work raw */
putchar(c);
}
/* use system call to set terminal behaviour to more normal behaviour */
system ("/bin/stty cooked");
return 0;
}
Please note that this isn't really optimal, since it just sort of assumes that stty cooked
is the behaviour you want when the program exits, rather than checking what the original terminal settings were. Also, since all special processing is skipped in raw mode, many key sequences (such as CTRL-C or CTRL-D) won't actually work as you expect them to without explicitly processing them in the program.
You can man stty
for more control over the terminal behaviour, depending exactly on what you want to achieve.
The classic way would be to add commas to the left and right:
select * from shirts where CONCAT(',', colors, ',') like '%,1,%'
But find_in_set also works:
select * from shirts where find_in_set('1',colors) <> 0
I have had the same problem in my project. I used an IntelliJ Idea 14 and Maven 8. And what I've noticed is that when I added a tomcat destination to to IDE it automaticly linked two jars from tomcat lib directory, they were servlet-api and jsp-api. Also I had them in my pom.xml. I killed a whole day trying to figure out why I'm getting java.lang.ClassNotFoundException: org.apache.jsp.index_jsp. And kewpiedoll99 is right. That is because there are dependency conflicts. When I added provided to those two jars in my pom.xml I found a happiness :)
Your "bad" output is UTF-8 displayed as CP1252.
On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:
df.to_csv('file.csv',encoding='utf-8-sig')
That encoder will add the BOM.
I'm afraid it's the best solution that I can think of. But you can use reserve() to pre-allocate the minimum required memory in advance to speed up things a bit. You'll end up with a new string that will probably be shorter but that takes up the same amount of memory, but you'll avoid reallocations.
EDIT: Depending on your situation, this may incur less overhead than jumbling characters around.
You should try different approaches and see what is best for you: you might not have any performance issues at all.
If you used read.table()
(or one of it's ilk, e.g. read.csv()
) then the easy fix is to change the call to:
read.table(file = "foo.txt", row.names = 1, ....)
where ....
are the other arguments you needed/used. The row.names
argument takes the column number of the data file from which to take the row names. It need not be the first column. See ?read.table
for details/info.
If you already have the data in R and can't be bothered to re-read it, or it came from another route, just set the rownames
attribute and remove the first variable from the object (assuming obj
is your object)
rownames(obj) <- obj[, 1] ## set rownames
obj <- obj[, -1] ## remove the first variable
Since your Print() method presumably deals with Text data, could you rewrite it to accept a TextWriter
parameter?
The library provides a StringWriter: TextWriter
but not a StringStream. I suppose you could create one by wrapping a MemoryStream, but is it really necessary?
After the Update:
void Main()
{
string myString; // outside using
using (MemoryStream stream = new MemoryStream ())
{
Print(stream);
myString = Encoding.UTF8.GetString(stream.ToArray());
}
...
}
You may want to change UTF8 to ASCII, depending on the encoding used by Print().
There are various scripts floating around that will do that depending on how crazy you want to get. I would personally use Pete Finnigan's find_all_privs script.
If you want to write it yourself, the query gets rather challenging. Users can be granted system privileges which are visible in DBA_SYS_PRIVS
. They can be granted object privileges which are visible in DBA_TAB_PRIVS
. And they can be granted roles which are visible in DBA_ROLE_PRIVS
(roles can be default or non-default and can require a password as well, so just because a user has been granted a role doesn't mean that the user can necessarily use the privileges he acquired through the role by default). But those roles can, in turn, be granted system privileges, object privileges, and additional roles which can be viewed by looking at ROLE_SYS_PRIVS
, ROLE_TAB_PRIVS
, and ROLE_ROLE_PRIVS
. Pete's script walks through those relationships to show all the privileges that end up flowing to a user.

Add config/secrets.yml
to version control and deploy again. You might need to remove a line from .gitignore
so that you can commit the file.
I had this exact same issue and it just turned out that the boilerplate .gitignore

.
This one is even simpler and execs no external commands.

Much simpler to my opinion:
sed -r 's/\s+//g' filename
someVar
value should be accessible only in some_function()
context, not from listener's.
If you like to have it within listener, you must do something like:
someObj.addEventListener("click",
function(){
var newVar = someVar;
some_function(someVar);
},
false);
and use newVar
instead.
The other way is to return someVar
value from some_function()
for using it further in listener (as a new local var):
var someVar = some_function(someVar);
I've just found a great tool for that need, it is called tabulate.
It prints tabular data and works with DataFrame
.
from tabulate import tabulate
import pandas as pd
df = pd.DataFrame({'col_two' : [0.0001, 1e-005 , 1e-006, 1e-007],
'column_3' : ['ABCD', 'ABCD', 'long string', 'ABCD']})
print(tabulate(df, headers='keys', tablefmt='psql'))
+----+-----------+-------------+
| | col_two | column_3 |
|----+-----------+-------------|
| 0 | 0.0001 | ABCD |
| 1 | 1e-05 | ABCD |
| 2 | 1e-06 | long string |
| 3 | 1e-07 | ABCD |
+----+-----------+-------------+
Note:
To suppress row indices for all types of data, pass
showindex="never"
orshowindex=False
.
You need to plug it into the task scheduler, such that it is launched after login of a user, using a user account that has administrative access on the system, with the highest privileges that are afforded to processes launched by that account.
This is the implementation that is used to autostart processes with administrative privileges when logging in as an ordinary user.
I've used it to launch the 'OpenVPN GUI' helper process which needs elevated privileges to work correctly, and thus would not launch properly from the registry key.
From the command line, you can create the task from an XML description of what you want to accomplish; so for example we have this, exported from my system, which would start notepad with the highest privileges when i log in:
<?xml version="1.0" encoding="UTF-16"?>

this answer should really be moved over to one of the other stackexchange sites, as it's not actually a programming question per se.
A UDF will only return a value it won't allow you to change the properties of a cell/sheet/workbook. Move your code to a Worksheet_Change event or similar to change properties.
Eg
Private Sub worksheet_change(ByVal target As Range)
target.Font.Bold = True
End Sub
@amro's answer translated to Swift 4.0:
if UserDefaults.standard.object(forKey: "FirstInstall") == nil {
UserDefaults.standard.set(false, forKey: "FirstInstall")
UserDefaults.standard.synchronize()
}
You have to check if the argument is undefined:
function func(a, b) {
if (a === undefined) a = "default value";
if (b === undefined) b = "default value";
}
You can always do:
int i, j;
for (i = j = 0; j < foo.length; ++j)
if (!"a".equals(foo[j])) foo[i++] = foo[j];
foo = Arrays.copyOf(foo, i);
I had the same issue and it was to do with my file name. If you set the file location using CD in CMD, and then type DIR it will list the files in that directory. Check that the file name appears and check that the spelling and filename ending is correct.
It should be .java but mine was .java.txt. The instructions on the Java tutorials website state that you should select "Save as Type Text Documents" but for me that always adds .txt onto the end of the file name. If I change it to "Save as Type All Documents" it correctly saved the file name.
Use expandRows()
from the splitstackshape
package:
library(splitstackshape)
expandRows(df, "freq")
Simple syntax, very fast, works on data.frame
or data.table
.
Result:
var1 var2
1 a d
2 b e
2.1 b e
3 c f
3.1 c f
3.2 c f
You could define a name for the VLOOKUP part of the formula.
=VLOOKUP(A1,B:B, 1, 0)
=IF( Value > 10, Value - 10, Value )
Step (1) is important here: I guess on the second row, you want Excel to use VLOOKUP(A2,B:B, 1, 0)
, the third row VLOOKUP(A3,B:B, 1, 0)
, etc. Step (4) achieves this by using relative references (A1
and B:B
), not absolute references ($A$1
and $B:$B
).
Note:
For newer Excel versions with the ribbon, go to Formulas ribbon -> Define Name. It's the same after that. Also, to use your name, you can do "Use in Formula", right under Define Name, while editing the formula, or else start typing it, and Excel will suggest the name (credits: Michael Rusch)
Shortened steps: 1. Right click a cell and click Define name... 2. Enter a name and the formula which you want to associate with that name/local variable 3. Use variable (credits: Jens Bodal)
I use this to avoid negative interval.

def oct(x):
return x*x
timeit.Timer("for x in range(100): oct(x)", "gc.enable()").timeit()
const express = require('express');_x000D_
let app = express();_x000D_
app.use(express.json());
_x000D_
This app.use(express.json) will now let you read the incoming post JSON object
In my experience I have seen Enum usage sometimes cause systems to be very difficult to change. If you are using an Enum for a set of domain-specific values that change frequently, and it has a lot of other classes and components that depend on it, you might want to consider not using an Enum.
For example, a trading system that uses an Enum for markets/exchanges. There are a lot of markets out there and it's almost certain that there will be a lot of sub-systems that need to access this list of markets. Every time you want a new market to be added to your system, or if you want to remove a market, it's possible that everything under the sun will have to be rebuilt and released.
A better example would be something like a product category type. Let's say your software manages inventory for a department store. There are a lot of product categories, and many reasons why this list of categories could change. Managers may want to stock a new product line, get rid of other product lines, and possibly reorganize the categories from time to time. If you have to rebuild and redeploy all of your systems simply because users want to add a product category, then you've taken something that should be simple and fast (adding a category) and made it very difficult and slow.
Bottom line, Enums are good if the data you are representing is very static over time and has a limited number of dependencies. But if the data changes a lot and has a lot of dependencies, then you need something dynamic that isn't checked at compile time (like a database table).
We managed installation of netbeans 6.8 under windows 8 successfully the following way:
-> installation executes without any errors
My suggested name for this technique (including multiple top-level classes in a single source file) would be "mess". Seriously, I don't think it's a good idea - I'd use a nested type in this situation instead. Then it's still easy to predict which source file it's in. I don't believe there's an official term for this approach though.
As for whether this actually changes between implementations - I highly doubt it, but if you avoid doing it in the first place, you'll never need to care :)
You can just use the global object.
var X = ['a', 'b', 'c'];
global.x = X;
console.log(x);

To see the performance difference, try this:
SELECT count(*)
FROM master..sysobjects as A
JOIN tempdb..sysobjects as B
on A.name = B.name
SELECT count(*)
FROM master..sysobjects as A
JOIN tempdb..sysobjects as B
on A.name LIKE B.name
Comparing strings with '=' is much faster.
You can implement Finite State Machine in two different ways.
Option 1:
Finite State machine with a pre-defined workflow : Recommended if you know all states in advance and state machine is almost fixed without any changes in future
Identify all possible states in your application
Identify all the events in your application
Identify all the conditions in your application, which may lead state transition
Occurrence of an event may cause transitions of state
Build a finite state machine by deciding a workflow of states & transitions.
e.g If an event 1 occurs at State 1, the state will be updated and machine state may still be in state 1.
If an event 2 occurs at State 1, on some condition evaluation, the system will move from State 1 to State 2
This design is based on State and Context patterns.
Have a look at Finite State Machine prototype classes.
Option 2:
Behavioural trees: Recommended if there are frequent changes to state machine workflow. You can dynamically add new behaviour without breaking the tree.
The base Task class provides a interface for all these tasks, the leaf tasks are the ones just mentioned, and the parent tasks are the interior nodes that decide which task to execute next.
The Tasks have only the logic they need to actually do what is required of them, all the decision logic of whether a task has started or not, if it needs to update, if it has finished with success, etc. is grouped in the TaskController class, and added by composition.
The decorators are tasks that “decorate” another class by wrapping over it and giving it additional logic.
Finally, the Blackboard class is a class owned by the parent AI that every task has a reference to. It works as a knowledge database for all the leaf tasks

A simple example for writing multiple data to excel at a time. And also when you want to append data to a sheet on a written excel file (closed excel file).
When it is your first time writing to an excel. (Writing "df1" and "df2" to "1st_sheet" and "2nd_sheet")
import pandas as pd
from openpyxl import load_workbook
df1 = pd.DataFrame([[1],[1]], columns=['a'])
df2 = pd.DataFrame([[2],[2]], columns=['b'])
df3 = pd.DataFrame([[3],[3]], columns=['c'])
excel_dir = "my/excel/dir"
with pd.ExcelWriter(excel_dir, engine='xlsxwriter') as writer:
df1.to_excel(writer, '1st_sheet')
df2.to_excel(writer, '2nd_sheet')
writer.save()
After you close your excel, but you wish to "append" data on the same excel file but another sheet, let's say "df3" to sheet name "3rd_sheet".
book = load_workbook(excel_dir)
with pd.ExcelWriter(excel_dir, engine='openpyxl') as writer:
writer.book = book
writer.sheets = dict((ws.title, ws) for ws in book.worksheets)
## Your dataframe to append.
df3.to_excel(writer, '3rd_sheet')
writer.save()
Be noted that excel format must not be xls, you may use xlsx one.

You can use the <datalist>
tag instead of the <select>
tag.
<input list="browsers" name="browser" id="browser">
<datalist id="browsers">
<option value="Edge">
<option value="Firefox">
<option value="Chrome">
<option value="Opera">
<option value="Safari">
</datalist>
You can use:
element = driver.find_element_by_class_name("class_name").text
This will return the text within the element and will allow you to verify it after that.
When i'm not root on the server, I use lsprofcalltree.py and run my program like this:
python lsprofcalltree.py -o callgrind.1 test.py
Then I can open the report with any callgrind-compatible software, like qcachegrind
You should note that div tag behaves like nothing and just let you to put something in it. It means that if you insert a paragraph with 100 lines of text within a div tag, it shows all the text but its height won't change to contain all the text.
So you have to use a CSS & HTML trick to handle this issue. This trick is very simple. you must use an empty div tag with class="clear" and then you will have to add this class to your CSS. Also note that your have #wrap in your CSS file but you don't have any tag with this id. In summary you have to change you code to something like below:
HTML Code:
<!-- Change "id" from "container" to "wrap" -->
<div id="wrap">
<div id="header">
</div>
<div id="navigation">
<a href="/" class="navigation">home</a>
<a href="about.php" class="navigation">about</a>
<a href="fanlisting.php" class="navigation">fanlisting</a>
<a href="reasons.php" class="navigation">100 reasons</a>
<a href="letter.php" class="navigation">letter</a>
</div>
<div id="content" >
<h1>Update Information</h1>
<iframe name="frame" id="frame" src="http://website.org/update.php" allowtransparency="true" frameborder="0"></iframe>
<!-- Add this line -->
<div class="clear"></div>
</div>
<div id="footer">
</div>
<!-- Add this line -->
<div class="clear"></div>
</div>
And also add this line to your CSS file:
.clear{ display: block; clear: both;}
The static keyword, when applied to a class, tells the compiler to create a single instance of that class. It is not then possible to 'new' one or more instance of the class. All methods in a static class must themselves be declared static.
It is possible, And often desirable, to have static methods of a non-static class. For example a factory method when creates an instance of another class is often declared static as this means that a particular instance of the class containing the factor method is not required.
For a good explanation of how, when and where see MSDN
There's one thing to keep in mind.
Mysqli does not support fetch_assoc() function which would return the columns with keys representing column names. Of course it's possible to write your own function to do that, it's not even very long, but I had really hard time writing it (for non-believers: if it seems easy to you, try it on your own some time and don't cheat :) )
So why is td default set to vertical-align: top;? I really don't know that yet. I would not dare to touch it. Instead add this to your stylesheet. It alters the buttons in the tables.
table .btn{
vertical-align: top;
}
If you like doing it using ruby:
ruby -e "`gem list`.split(/$/).each { |line| puts `gem uninstall -Iax #{line.split(' ')[0]}` unless line.strip.empty? }"

Here is the way I look at COALESCE...and hopefully it makes sense...
In a simplistic form….
Coalesce(FieldName, 'Empty')
So this translates to…If "FieldName" is NULL, populate the field value with the word "EMPTY".
Now for mutliple values...
Coalesce(FieldName1, FieldName2, Value2, Value3)
If the value in Fieldname1 is null, fill it with the value in Fieldname2, if FieldName2 is NULL, fill it with Value2, etc.
This piece of test code for the AdventureWorks2012 sample database works perfectly & gives a good visual explanation of how COALESCE works:
SELECT Name, Class, Color, ProductNumber,
COALESCE(Class, Color, ProductNumber) AS FirstNotNull
FROM Production.Product
cardeal's answer was really helpful. Took it a little further and figured it may help others some where down the line. Here is the fiddle:

This can be done through the youtube player API:
Working example:

// create youtube player
var player;
function onYouTubePlayerAPIReady() {
player = new YT.Player('player', {

}
// autoplay video
function onPlayerReady(event) {
event.target.playVideo();

Once you have put the values into the JSONObject then put the JSONObject into the JSONArray staright after.
Something like this maybe:
jsonObj.put("value1", 1);
jsonObj.put("value2", 900);
jsonObj.put("value3", 1368349);
jsonArray.put(jsonObj);
Then create new JSONObject, put the other values into it and add it to the JSONArray:
jsonObj.put("value1", 2);
jsonObj.put("value2", 1900);
jsonObj.put("value3", 136856);
jsonArray.put(jsonObj);
When this method executes, it retrieves the content of location.href
, but then jQuery parses the returned document to find the element with divId
. This element, along with its contents, is inserted into the element with an ID (divId
) of result, and the rest of the retrieved document is discarded.
$("#divId").load(location.href + " #divId>*", "");
hope this may help someone to understand

I have a similar scenario, and had no problem connecting after setting the JNLP port as you describe, and adding a single firewall rule allowing a connection on the server using that port. Granted it is a randomly selected client port going to a known server port (a host:ANY -> server:1 rule is needed).
From my reading of the source code, I don't see a way to set the local port to use when making the request from the slave. It's unfortunate, it would be a nice feature to have.
Alternatives:
Use a simple proxy on your client that listens on port N and then does forward all data to the actual Jenkins server on the remote host using a constant local port. Connect your slave to this local proxy instead of the real Jenkins server.
Create a custom Jenkins slave build that allows an option to specify the local port to use.
Remember also if you are using HTTPS via a self-signed certificate, you must alter the configuration jenkins-slave.xml file on the slave to specify the -noCertificateCheck option on the command line.
Just had this in VS 2010.
Fixed by editing the .sln file and changing the TargetFrameworkMoniker to have the value ".NETFramework,Version%3Dv4.0" assigned to it.

You can use only two commands to revert a merge or restart by a specific commit:
git reset --hard commitHash
(you should use the commit that you want to restart, eg. 44a587491e32eafa1638aca7738)git push origin HEAD --force
(Sending the new local master branch to origin/master)Good luck and go ahead!
Driver manager logs can be used to get console logs from browser and it will help to identify errors appears in console.

{
LogEntries log= driver.manage().logs().get("browser")
List<LogEntry> logs=log.getAll();
return logs;

You certainly are able to have multiple CTEs in a single query expression. You just need to separate them with a comma. Here is an example. In the example below, there are two CTEs. One is named CategoryAndNumberOfProducts
and the second is named ProductsOverTenDollars
.
WITH CategoryAndNumberOfProducts (CategoryID, CategoryName, NumberOfProducts) AS
(
SELECT
CategoryID,
CategoryName,
(SELECT COUNT(1) FROM Products p
WHERE p.CategoryID = c.CategoryID) as NumberOfProducts
FROM Categories c
),
ProductsOverTenDollars (ProductID, CategoryID, ProductName, UnitPrice) AS
(
SELECT
ProductID,
CategoryID,
ProductName,
UnitPrice
FROM Products p
WHERE UnitPrice > 10.0
)
SELECT c.CategoryName, c.NumberOfProducts,
p.ProductName, p.UnitPrice
FROM ProductsOverTenDollars p
INNER JOIN CategoryAndNumberOfProducts c ON
p.CategoryID = c.CategoryID
ORDER BY ProductName
The Content-Type
header is just used as info for your application. The browser doesn't care what it is. The browser just returns you the data from the AJAX call. If you want to parse it as JSON, you need to do that on your own.
The header is there so your app can detect what data was returned and how it should handle it. You need to look at the header, and if it's application/json
then parse it as JSON.
This is actually how jQuery works. If you don't tell it what to do with the result, it uses the Content-Type
to detect what to do with it.
Make sure you are running the test as a superuser.
sudo nginx -t
Or the test wont have all the permissions needed to complete the test properly.
Don't forget to inject $location
into controller.
sed -e 's/Here\(.*\)String/\1/'
The api is fairly easy to use.
// Lookup the dns, if the ip exists.
if (!ip.isEmpty()) {
InetAddress inetAddress = InetAddress.getByName(ip);
dns = inetAddress.getCanonicalHostName();
}
In this approach only one statement is executed when the UPDATE is successful.
-- For each row in source
BEGIN TRAN
UPDATE target
SET <target_columns> = <source_values>
WHERE <target_expression>
IF (@@ROWCOUNT = 0)
INSERT target (<target_columns>)
VALUES (<source_values>)
COMMIT
This can be considered as bit tricky way as in my situation, I can't use a CTE table, so decided to join with sys.all_objects
and then created row numbers and added that to start date till it reached the end date.
See the code below where I generated all dates in Jul 2018. Replace hard coded dates with your own variables (tested in SQL Server 2016):
select top (datediff(dd, '2018-06-30', '2018-07-31')) ROW_NUMBER()
over(order by a.name) as SiNo,
Dateadd(dd, ROW_NUMBER() over(order by a.name) , '2018-06-30') as Dt from sys.all_objects a

** Update ** A scalars converter has been added to retrofit that allows for a String
response with less ceremony than my original answer below.
Example interface --
public interface GitHubService {
@GET("/users/{user}")
Call<String> listRepos(@Path("user") String user);
}
Add the ScalarsConverterFactory
to your retrofit builder. Note: If using ScalarsConverterFactory
and another factory, add the scalars factory first.
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(ScalarsConverterFactory.create())
// add other factories here, if needed.
.build();
You will also need to include the scalars converter in your gradle file --
implementation 'com.squareup.retrofit2:converter-scalars:2.1.0'
--- Original Answer (still works, just more code) ---
I agree with @CommonsWare that it seems a bit odd that you want to intercept the request to process the JSON yourself. Most of the time the POJO has all the data you need, so no need to mess around in JSONObject
land. I suspect your specific problem might be better solved using a custom gson TypeAdapter
or a retrofit Converter
if you need to manipulate the JSON. However, retrofit provides more the just JSON parsing via Gson. It also manages a lot of the other tedious tasks involved in REST requests. Just because you don't want to use one of the features, doesn't mean you have to throw the whole thing out. There are times you just want to get the raw stream, so here is how to do it -
First, if you are using Retrofit 2, you should start using the Call
API. Instead of sending an object to convert as the type parameter, use ResponseBody
from okhttp --
public interface GitHubService {
@GET("/users/{user}")
Call<ResponseBody> listRepos(@Path("user") String user);
}
then you can create and execute your call --
GitHubService service = retrofit.create(GitHubService.class);
Call<ResponseBody> result = service.listRepos(username);
result.enqueue(new Callback<ResponseBody>() {
@Override
public void onResponse(Response<ResponseBody> response) {
try {
System.out.println(response.body().string());
} catch (IOException e) {
e.printStackTrace();
}
}
@Override
public void onFailure(Throwable t) {
e.printStackTrace();
}
});
Note The code above calls string()
on the response object, which reads the entire response into a String. If you are passing the body off to something that can ingest streams, you can call charStream()
instead. See the ResponseBody
docs.
private void startFloatingWidgetService() {
startService(new Intent(MainActivity.this,FloatingWidgetService.class)
.setAction(FloatingWidgetService.ACTION_PLAY));
}
instead of :
private void startFloatingWidgetService() {
startService(new Intent(FloatingWidgetService.ACTION_PLAY));
}
Because when you try 2nd one then you get an error saying : java.lang.IllegalArgumentException: Service Intent must be explicit: Intent { act=com.floatingwidgetchathead_demo.SampleService.ACTION_START }
Then your Service be like this :
static final String ACTION_START = "com.floatingwidgetchathead_demo.SampleService.ACTION_START";
static final String ACTION_PLAY = "com.floatingwidgetchathead_demo.SampleService.ACTION_PLAY";
static final String ACTION_PAUSE = "com.floatingwidgetchathead_demo.SampleService.ACTION_PAUSE";
static final String ACTION_DESTROY = "com.yourcompany.yourapp.SampleService.ACTION_DESTROY";
@SuppressLint("LogConditional")
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
String action = intent.getAction();
//System.out.println("ACTION: "+action);
switch (action){
case ACTION_START:
Log.d(TAG, "onStartCommand: "+action);
break;
case ACTION_PLAY:
Log.d(TAG, "onStartCommand: "+action);
addRemoveView();
addFloatingWidgetView();
break;
case ACTION_PAUSE:
Log.d(TAG, "onStartCommand: "+action);
break;
case ACTION_DESTROY:
Log.d(TAG, "onStartCommand: "+action);
break;
}
return START_STICKY;
}

I ran into a similar problem and just passed the end of the array to the ArrayList.add()
index param like so:
public class Stack {
private ArrayList<String> stringList = new ArrayList<String>();
RandomStringGenerator rsg = new RandomStringGenerator();
private void push(){
String random = rsg.randomStringGenerator();
stringList.add(stringList.size(), random);
}
}
It's very simple, trying to explain in a simple word. get the today's date as below
Calendar calendar = Calendar.getInstance();
System.out.println(calendar.getTime());// print today's date
calendar.add(Calendar.DATE, 1);
Now set one day ahead with this date by calendar.add method which takes (constant, value). Here constant could be DATE, hours, min, sec etc. and value is the value of constant. Like for one day, ahead constant is Calendar.DATE and its value are 1 because we want one day ahead value.
System.out.println(calendar.getTime());// print modified date which is
tomorrow's date
Thanks
setRetaininstance
is only useful when your activity
is destroyed and recreated due to a configuration change because the instances are saved during a call to onRetainNonConfigurationInstance
. That is, if you rotate the device, the retained fragments will remain there(they're not destroyed and recreated.) but when the runtime kills the activity to reclaim resources, nothing is left. When you press back button and exit the activity, everything is destroyed.
Usually I use this function to saved orientation changing Time.Say I have download a bunch of Bitmaps from server and each one is 1MB, when the user accidentally rotate his device, I certainly don't want to do all the download work again.So I create a Fragment
holding my bitmaps and add it to the manager and call setRetainInstance
,all the Bitmaps are still there even if the screen orientation changes.

An ioctl
, which means "input-output control" is a kind of device-specific system call. There are only a few system calls in Linux (300-400), which are not enough to express all the unique functions devices may have. So a driver can define an ioctl which allows a userspace application to send it orders. However, ioctls are not very flexible and tend to get a bit cluttered (dozens of "magic numbers" which just work... or not), and can also be insecure, as you pass a buffer into the kernel - bad handling can break things easily.
An alternative is the sysfs
interface, where you set up a file under /sys/
and read/write that to get information from and to the driver. An example of how to set this up:
static ssize_t mydrvr_version_show(struct device *dev,
struct device_attribute *attr, char *buf)
{
return sprintf(buf, "%s\n", DRIVER_RELEASE);
}
static DEVICE_ATTR(version, S_IRUGO, mydrvr_version_show, NULL);
And during driver setup:
device_create_file(dev, &dev_attr_version);
You would then have a file for your device in /sys/
, for example, /sys/block/myblk/version
for a block driver.
Another method for heavier use is netlink, which is an IPC (inter-process communication) method to talk to your driver over a BSD socket interface. This is used, for example, by the WiFi drivers. You then communicate with it from userspace using the libnl
or libnl3
libraries.
Check this one. hope it will help full for you.

Ok, so here was my process:
keytool -list -v -keystore permanent.jks
- got me the alias.
keytool -export -alias alias_name -file certificate_name -keystore permanent.jks
- got me the certificate to import.
Then I could import it with the keytool:
keytool -import -alias alias_name -file certificate_name -keystore keystore location
As @Christian Bongiorno says the alias can't already exist in your keystore.

If you are having problems with resetting the state/region on country change try clearing the current value with
$("#dropdown").select2("val", "");
You can view the documentation here http://ivaynberg.github.io/select2/ that outlines nearly/all features. Select2 supports events such as change
that can be used to update the subsequent dropdowns.
$("#dropdown").on("change", function(e) {});
You can now update the data/list without rebuilding the control using:
fooBarDropdown.select2({
data: fromAccountData
});
The JavaScript try…catch mechanism cannot be used to intercept errors generated by asynchronous APIs. A common mistake for beginners is to try to use throw inside an error-first callback:
// THIS WILL NOT WORK:
const fs = require('fs');
try {
fs.readFile('/some/file/that/does-not-exist', (err, data) => {
// Mistaken assumption: throwing here...
if (err) {
throw err;
}
});
} catch (err) {
// This will not catch the throw!
console.error(err);
}
This will not work because the callback function passed to fs.readFile() is called asynchronously. By the time the callback has been called, the surrounding code, including the try…catch block, will have already exited. Throwing an error inside the callback can crash the Node.js process in most cases. If domains are enabled, or a handler has been registered with process.on('uncaughtException'), such errors can be intercepted.

I've had various problems (see below) installing upgraded SSL modules, even inside a virtualenv, on top of older OS-provided Python versions, so I now use pyenv
.
pyenv makes it very easy to install new Python versions and supports virtualenvs. Getting started is much easier than the recipes for virtualenv listed in other answers:
brew install pyenv
and on Linux, use pyenv-installerThis works very well to insulate the "new Python" version and virtualenv from system Python. Because you can easily use a more recent Python (post 2.7.9), the SSL modules are already upgraded, and of course like any modern virtualenv setup you are insulated from the system Python modules.
A couple of nice tutorials:
pyenv global 3.6.1
(global to current user) or pyenv local 2.7.13
(local to current directory).The pyenv-virtualenv
plugin is now built in - type pyenv commands | grep virtualenv
to check. I wouldn't use the pyenv-virtualenvwrapper plugin to start with - see how you get on with pyenv-virtualenv which is more integrated into pyenv, as this covers most of what virtualenvwrapper does.
pyenv
is modelled on rbenv
(a good tool for Ruby version switching) and its only dependency is bash.
pyvenv
- that is a virtualenv equivalent that's part of recent Python 3 versions, and doesn't handle Python version switchingTwo warnings about pyenv:
dash
, which is /bin/sh
on Ubuntu or Debian.bash --login
using a terminal), which is not always easy to achieve with automation tools such as Ansible.Hence pyenv is best for interactive use, and less good for scripting servers.
One reason to use pyenv
was that there were often problems with upgrading Python SSL modules when using older system-provided Python versions. This may be less of a problem now that current Linux distributions support Python 3.x.
You can use the "cookies" npm module, which has a comprehensive set of features.

in my case innodb_data_home_dir was no longer correct because I had shuffled some drive letters around when I added a new drive to my system
I have tried methods above, but still no module named 'MySQLdb', finally, I succeed with
easy_install mysql-python
my env is unbuntu 14.04
Use this query to create the new table with the values from existing table
CREATE TABLE New_Table_name AS SELECT * FROM Existing_table_Name;
Now you can get all the values from existing table into newly created table.
As other have answered, the result is exactly the same, None
is returned in all cases.
The difference is stylistic, but please note that PEP8 requires the use to be consistent:
Be consistent in return statements. Either all return statements in a function should return an expression, or none of them should. If any return statement returns an expression, any return statements where no value is returned should explicitly state this as return None, and an explicit return statement should be present at the end of the function (if reachable).
Yes:
def foo(x): if x >= 0: return math.sqrt(x) else: return None def bar(x): if x < 0: return None return math.sqrt(x)
No:
def foo(x): if x >= 0: return math.sqrt(x) def bar(x): if x < 0: return return math.sqrt(x)
https://www.python.org/dev/peps/pep-0008/#programming-recommendations
Basically, if you ever return non-None
value in a function, it means the return value has meaning and is meant to be caught by callers. So when you return None
, it must also be explicit, to convey None
in this case has meaning, it is one of the possible return values.
If you don't need return at all, you function basically works as a procedure instead of a function, so just don't include the return
statement.
If you are writing a procedure-like function and there is an opportunity to return earlier (i.e. you are already done at that point and don't need to execute the remaining of the function) you may use empty an return
s to signal for the reader it is just an early finish of execution and the None
value returned implicitly doesn't have any meaning and is not meant to be caught (the procedure-like function always returns None
anyway).
Update (2019, latest)
Since Jan 2019, GitHub allows private repositories for up to three collaborators.
Previous answer:
Here is the comparison for free plans listed by tree main Git Cloud based solutions:
Here is the comparison for paid plans listed by tree main Git Cloud based solutions:
I'm not seeing people mentioning GitLab here, but it seems like the best free private plan for me. I myself am using it with no problems.
GitHub: If you have a student account or want to pay for $7 monthly, GitHub has the biggest community and you can take advantage of it's public repositories, forks, etc.
Bitbucket: If you use other products from Atlassian like Jira or Confluence, Bitbucket works great with them.
GitLab: Everything that I care about (free private repository, number of private repositories, number of collaborators, etc.) are offered for free. This seems like the best choice for me.
The following command will run tar in a container with all named data volumes mounted, and redirect the output into a file:
docker run --rm `docker volume list -q | egrep -v '^.{64}$' | awk '{print "-v " $1 ":/mnt/" $1}'` alpine tar -C /mnt -cj . > data-volumes.tar.bz2
Make sure to test the resulting archive in case something went wrong:
tar -tjf data-volumes.tar.bz2
Here's the intended way to convert a String to a Date:
String timestamp = "2011-10-02-18.48.05.123";
DateFormat df = new SimpleDateFormat("yyyy-MM-dd-kk.mm.ss.SSS");
Date parsedDate = df.parse(timestamp);
Admittedly, it only has millisecond resolution, but in all services slower than Twitter, that's all you'll need, especially since most machines don't even track down to the actual nanoseconds.
You can use islower()
on your string to see if it contains some lowercase letters (amongst other characters). or
it with isupper()
to also check if contains some uppercase letters:
below: letters in the string: test yields true
>>> z = "(555) 555 - 5555 ext. 5555"
>>> z.isupper() or z.islower()
True
below: no letters in the string: test yields false.
>>> z= "(555).555-5555"
>>> z.isupper() or z.islower()
False
>>>
Not to be mixed up with isalpha()
which returns True
only if all characters are letters, which isn't what you want.
Note that Barm's answer completes mine nicely, since mine doesn't handle the mixed case well.
Here's what works for me to get the line number in Python 3.7.3 in VSCode 1.39.2 (dmsg
is my mnemonic for debug message):
import inspect
def dmsg(text_s):
print (str(inspect.currentframe().f_back.f_lineno) + '| ' + text_s)
To call showing a variable name_s
and its value:
name_s = put_code_here
dmsg('name_s: ' + name_s)
Output looks like this:
37| name_s: value_of_variable_at_line_37
In short, no. You cannot autowire or manually wire static fields in Spring. You'll have to write your own logic to do this.
You could use the following code.
print_r($_SESSION);
Presumably you have it in a variable and are using JSON.parse(data);
. In which case, use:
JSON.parse(data.replace(/"/g,'"'));
You might want to fix your JSON-writing script though, because "
is not valid in a JSON object.
The command that sold me on git personally was bisect. I don't think that this feature is available in any other version control system as of now.
That being said, if people are used to a GUI client for source control they are not going to be impressed with git. Right now the only full-featured client is command-line.
Even easier: just store the R.drawable
id in the view's id: use v.setId()
. Then get it back with v.getId()
.
As one person may have already suggested,
I passed the ISO 8601 date string directly to moment like so...
`moment.utc('2019-11-03T05:00:00.000Z').format('MM/DD/YYYY')`
or
`moment('2019-11-03T05:00:00.000Z').utc().format('MM/DD/YYYY')`
either of these solutions will give you the same result.
`console.log(moment('2019-11-03T05:00:00.000Z').utc().format('MM/DD/YYYY')) // 11/3/2019`
If you want to use environment variable during build. Lets say setting username and password.
username= Ubuntu
password= swed24sw
Dockerfile
FROM ubuntu:16.04
ARG SMB_PASS
ARG SMB_USER
# Creates a new User
RUN useradd -ms /bin/bash $SMB_USER
# Enters the password twice.
RUN echo "$SMB_PASS\n$SMB_PASS" | smbpasswd -a $SMB_USER
Terminal Command
docker build --build-arg SMB_PASS=swed24sw --build-arg SMB_USER=Ubuntu . -t IMAGE_TAG
If you use it in a database, this is a good way:
Set the ip field in database to varchar(250), and then use this:
$theip = $_SERVER["REMOTE_ADDR"];
if (!empty($_SERVER["HTTP_X_FORWARDED_FOR"])) {
$theip .= '('.$_SERVER["HTTP_X_FORWARDED_FOR"].')';
}
if (!empty($_SERVER["HTTP_CLIENT_IP"])) {
$theip .= '('.$_SERVER["HTTP_CLIENT_IP"].')';
}
$realip = substr($theip, 0, 250);
Then you just check $realip against the database ip field
This is not mentioned in you post but I suspect you are initiating an SSL connection from the browser to Apache, where VirtualHosts are configured, and Apache does a revese proxy to your Tomcat.
There is a serious bug in (some versions ?) of IE that sends the 'wrong' host information in an SSL connection (see EDIT below) and confuses the Apache VirtualHosts. In short the server name presented is the one of the reverse DNS resolution of the IP, not the one in the URL.
The workaround is to have one IP address per SSL virtual hosts/server name. Is short, you must end up with something like
1 server name == 1 IP address == 1 certificate == 1 Apache Virtual Host
EDIT
Though the conclusion is correct, the identification of the problem is better described here http://en.wikipedia.org/wiki/Server_Name_Indication
You can also set the TMPDIR
environment variable.
In some situations (Docker in my case) it's more convenient to set an environment variable than to update a config file.
To disable right click context menu on all images of a page simply do this with following:
jQuery(document).ready(function(){
// Disable context menu on images by right clicking
for(i=0;i<document.images.length;i++) {
document.images[i].onmousedown = protect;
}
});
function protect (e) {
//alert('Right mouse button not allowed!');
this.oncontextmenu = function() {return false;};
}
You can use:
String.prototype.replaceAll = function(search, replace) {
if (replace === undefined) {
return this.toString();
}
return this.split(search).join(replace);
}
1. grant privileges
mysql> GRANT ALL PRIVILEGES ON . TO 'root'@'%'WITH GRANT OPTION;
mysql> FLUSH PRIVILEGES
2. check user table:
mysql> use mysql
mysql> select host,user from user
3.Modify the configuration file
mysql default bind ip:127.0.0.1, if we want to remote visit services,just delete config
#Modify the configuration file
vi /usr/local/etc/my.cnf
#Comment out the ip-address option
[mysqld]
# Only allow connections from localhost
#bind-address = 127.0.0.1
4.finally restart the services
brew services restart mysql
If all of these rows are related and you need to alter the tabular data ... why not just wrap the entire table in a form, and change GET to POST (unless you know that you're not going to be sending more than the max amount of data a GET request can send).
I cannot wrap the entire table in a form, because some input fields of each row are input type="file" and files may be large. When the user submits the form, I want to POST only fields of current row, not all fields of the all rows which may have unneeded huge files, causing form to submit very slowly.
So, I tried incorrect nesting: tr/form and form/tr. However, it works only when one does not try to add new inputs dynamically into the form. Dynamically added inputs will not belong to incorrectly nested form, thus won't get submitted. (valid form/table dynamically inputs are submitted just fine).
Nesting div[display:table]/form/div[display:table-row]/div[display:table-cell] produced non-uniform widths of grid columns. I managed to get uniform layout when I replaced div[display:table-row] to form[display:table-row] :
div.grid {
display: table;
}
div.grid > form {
display: table-row;
div.grid > form > div {
display: table-cell;
}
div.grid > form > div.head {
text-align: center;
font-weight: 800;
}
For the layout to be displayed correctly in IE8:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
...
<meta http-equiv="X-UA-Compatible" content="IE=8, IE=9, IE=10" />
Sample of output:
<div class="grid" id="htmlrow_grid_item">
<form>
<div class="head">Title</div>
<div class="head">Price</div>
<div class="head">Description</div>
<div class="head">Images</div>
<div class="head">Stock left</div>
<div class="head">Action</div>
</form>
<form action="/index.php" enctype="multipart/form-data" method="post">
<div title="Title"><input required="required" class="input_varchar" name="add_title" type="text" value="" /></div>
It would be much harder to make this code work in IE6/7, however.
This always works for me:
import android.app.Activity;
import android.content.Context;
public class yourClass {
Context ctx;
public yourClass (Handler handler, Context context) {
super(handler);
ctx = context;
}
//Use context (ctx) in your code like this:
block1 = new Droid(BitmapFactory.decodeResource(ctx.getResources(), R.drawable.birdpic), 100, 10);
//OR
builder.setLargeIcon(BitmapFactory.decodeResource(ctx.getResources(), R.drawable.birdpic));
//OR
final Intent intent = new Intent(ctx, MainActivity.class);
//OR
NotificationManager notificationManager = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);
//ETC...
}
Not related to this question but example using a Fragment to access system resources/activity like this:
public boolean onQueryTextChange(String newText) {
Activity activity = getActivity();
Context context = activity.getApplicationContext();
returnSomething(newText);
return false;
}
View customerInfo = getActivity().getLayoutInflater().inflate(R.layout.main_layout_items, itemsLayout, false);
itemsLayout.addView(customerInfo);
Below is a fully functional example of what I believe you're trying to do (with a functional snippet).
Based on your question, you seem to be modifying 1 property in state
for all of your elements. That's why when you click on one, all of them are being changed.
In particular, notice that the state tracks an index of which element is active. When MyClickable
is clicked, it tells the Container
its index, Container
updates the state
, and subsequently the isActive
property of the appropriate MyClickable
s.

state = {_x000D_
activeIndex: null_x000D_

In response to a comment about a "loop" version, I believe the question is about rendering an array of MyClickable
elements. We won't use a loop, but map, which is typical in React + JSX. The following should give you the same result as above, but it works with an array of elements.
// New render method for `Container`
render() {
const clickables = [
{ name: "a" },
{ name: "b" },
{ name: "c" },
]
return <div>
{ clickables.map(function(clickable, i) {
return <MyClickable key={ clickable.name }
name={ clickable.name }
index={ i }
isActive={ this.state.activeIndex === i }
onClick={ this.handleClick }
/>
} )
}
</div>
}
An authority is a portion of a URI. Your error suggests that it was not expecting one. The authority section is shown below, it is what is known as the website part of the url.
From RFC3986 on URIs:
The following is an example URI and its component parts:
foo://example.com:8042/over/there?name=ferret#nose
\_/ \______________/\_________/ \_________/ \__/
| | | | |
scheme authority path query fragment
| _____________________|__
/ \ / \
urn:example:animal:ferret:nose
So there are two formats, one with an authority and one not. Regarding slashes:
"When authority is not present, the path cannot begin with two slash
characters ("//")."
Source: https://tools.ietf.org/rfc/rfc3986.txt (search for text 'authority is not present, the path cannot begin with two slash')

In 9.4.4 using the #>>
operator works for me:
select to_json('test'::text) #>> '{}';
To use with a table column:
select jsoncol #>> '{}' from mytable;
string[] result = new string[table.Columns.Count];
DataRow dr = table.Rows[0];
for (int i = 0; i < dr.ItemArray.Length; i++)
{
result[i] = dr[i].ToString();
}
foreach (string str in result)
Console.WriteLine(str);
Engine must be before select:
CREATE TEMPORARY TABLE temp1 ENGINE=MEMORY

You can use the below code on your string and you will get the complete string without html part.
string title = "<b> Hulk Hogan's Celebrity Championship Wrestling <font color=\"#228b22\">[Proj # 206010]</font></b> (Reality Series, )".Replace(" ",string.Empty);
string s = Regex.Replace(title, "<.*?>", String.Empty);

It is not recommended to call gc explicitly, but if you call
GC.Collect();
GC.WaitForPendingFinalizers();
It will call GC explicitly throughout your code, don't forget to call GC.WaitForPendingFinalizers();
after GC.Collect()
.
In such cases, you are better off re-adding the whitespace which makes the syntax error immediate apparent:
function(){
if(xmlhttp.readyState==4&&xmlhttp.status==200){
document.getElementById("content").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","data/"+id+".html",true);xmlhttp.send();
}
There's a } too many. Also, after the closing } of the function, you should add a ; before the xmlhttp.open()
And finally, I don't see what that anonymous function does up there. It's never executed or referenced. Are you sure you pasted the correct code?
=TO_DATE(TO_PURE_NUMBER(Insert Date cell, i.e. AM4)
+[how many days to add in numbers, e.g. 3 days])
Looks like in practice:
=TO_DATE(TO_PURE_NUMBER(AM4)+3)
Essentially you are converting the date into a pure number and back into a date again.

.dialog({
autoOpen: false,

height: 625,
width: 500,
title: "Some title"
});
$dialog.dialog('open');
Use this inside a function. This is great if you really want to load an external URL as an IFRAME. Also make sure that in you custom jqueryUI you have the dialog.
The link to a function in a dynamic library is resolved when the library is loaded or at run time. Therefore, both the executable file and dynamic library are loaded into memory when the program is run. The memory address at which a dynamic library is loaded cannot be determined in advance, because a fixed address might clash with another dynamic library requiring the same address.
There are two commonly used methods for dealing with this problem:
1.Relocation. All pointers and addresses in the code are modified, if necessary, to fit the actual load address. Relocation is done by the linker and the loader.
2.Position-independent code. All addresses in the code are relative to the current position. Shared objects in Unix-like systems use position-independent code by default. This is less efficient than relocation if program run for a long time, especially in 32-bit mode.
The name "position-independent code" actually implies following:
The code section contains no absolute addresses that need relocation, but only self relative addresses. Therefore, the code section can be loaded at an arbitrary memory address and shared between multiple processes.
The data section is not shared between multiple processes because it often contains writeable data. Therefore, the data section may contain pointers or addresses that need relocation.
All public functions and public data can be overridden in Linux. If a function in the main executable has the same name as a function in a shared object, then the version in main will take precedence, not only when called from main, but also when called from the shared object. Likewise, when a global variable in main has the same name as a global variable in the shared object, then the instance in main will be used, even when accessed from the shared object.
This so-called symbol interposition is intended to mimic the behavior of static libraries.
A shared object has a table of pointers to its functions, called procedure linkage table (PLT) and a table of pointers to its variables called global offset table (GOT) in order to implement this "override" feature. All accesses to functions and public variables go through this tables.
p.s. Where dynamic linking cannot be avoided, there are various ways to avoid the timeconsuming features of the position-independent code.

I think the most correct answer, assuming the use of jQuery, is a consolidation of aspects of all the answers in this page, plus the use of the event that Bootstrap passes:
$(document).on('shown.bs.modal', function(e) {
$('input:visible:enabled:first', e.target).focus();
});
It also would work changing $(document)
to $('.modal')
or to add a class to the modal that signals that this focus should occur, like $('.modal.focus-on-first-input')
