Besides the solution of m79lkm above, my 2 cents on this topic is not to directly pipe the result in gzip but first dump it as a .sql file, and then gzip it. (Use && instead of | )
The dump itself will be faster. (for what I tested it was double as fast)
Otherwise you tables will be locked longer and the downtime/slow-responding of your application can bother the users. The mysqldump command is taking a lot of resources from your server.
So I would go for "&& gzip" instead of "| gzip"
Important: check for free disk space first with df -h
since you will need more then piping | gzip.
mysqldump -u user -p[user_password] [database_name] > dumpfilename.sql && gzip dumpfilename.sql
-> which will also result in 1 file called dumpfilename.sql.gz
Furthermore the option --single-transaction
prevents the tables being locked but still result in a solid backup. So you might consider to use that option. See docs here
mysqldump --single-transaction -u user -p[user_password] [database_name] > dumpfilename.sql && gzip dumpfilename.sql

I tried the solution below

$array = explode("\r\n", trim($jobs)); // trim() gets rid of the last \r\n
foreach ($array as $key => $item) {
if ($item == '') {
unset($array[$key]);
}
}
return $array;
}
static private function arrayToString($jobs = array()) {
$string = implode("\r\n", $jobs);
return $string;
}
static public function getJobs() {
$output = shell_exec('crontab -l');
return self::stringToArray($output);
}

As seen in Install crontab on CentOS, the crontab package in CentOS is vixie-cron
. Hence, do install it with:
yum install vixie-cron
And then start it with:
service crond start
To make it persistent, so that it starts on boot, use:
chkconfig crond on
On CentOS 7 you need to use cronie
:
yum install cronie
On CentOS 6 you can install vixie-cron
, but the real package is cronie
:
yum install vixie-cron
and
yum install cronie
In both cases you get the same output:

You need to also install cygrunsrv
so you can set cron up as a windows service, then run cron-config
.
If you want the cron jobs to send email of any output you'll also need to install either exim
or ssmtp
(before running cron-config
.)
See /usr/share/doc/Cygwin/cron-*.README
for more details.
Regarding programs without a .exe
extension, they are probably shell scripts of some type. If you look at the first line of the file you could see what program you need to use to run them (e.g., "#!/bin/sh
"), so you could perhaps execute them from the windows scheduler by calling the shell program (e.g., "C:\cygwin\bin\sh.exe -l /my/cygwin/path/to/prog
".)
use
path_to_exe >> log_file
to see the output of your command also errors can be redirected with
path_to_exe &> log_file
also you can use
crontab -l
to check if your edits were saved.
you can write multiple lines in case of different minutes, for example you want to run at 10:01 AM and 2:30 PM
1 10 * * * php -f /var/www/package/index.php controller function
30 14 * * * php -f /var/www/package/index.php controller function
but the following is the best solution for running cron multiple times in a day as minutes are same, you can mention hours like 10,30
.
30 10,14 * * * php -f /var/www/package/index.php controller function
You can also use day names like Mon
for Monday, Tue
for Tuesday, etc. It's more human friendly.
The unix setup should be like the following:
0 */3 * * * sh cron/update_old_citations.sh
good reference for how to set various settings in cron at: http://www.thegeekstuff.com/2011/07/cron-every-5-minutes/
every minute:
* * * * * /path/to/php /var/www/html/a.php
every 24hours (every midnight):
0 0 * * * /path/to/php /var/www/html/reset.php
See this reference for how crontab works: http://adminschoice.com/crontab-quick-reference, and this handy tool to build cron jobx: http://www.htmlbasix.com/crontab.shtml
An easy way to write cron is to use the online cron generator It will generate the line for you. One thing to note is that if you wish to run it each day (not just weekdays) you need to highlight all the days.
Even more simple answer to you question would be:
echo "0 1 * * * /root/test.sh" | tee -a /var/spool/cron/root
You can setup cronjobs on remote servers as below:
#!/bin/bash
servers="srv1 srv2 srv3 srv4 srv5"
for i in $servers
do
echo "0 1 * * * /root/test.sh" | ssh $i " tee -a /var/spool/cron/root"
done
In Linux, the default location of the crontab
file is /var/spool/cron/
. Here you can find the crontab
files of all users. You just need to append your cronjob entry to the respective user's file. In the above example, the root user's crontab file is getting appended with a cronjob to run /root/test.sh
every day at 1 AM.
You can also try using runuser
(as root) to run a command as a different user
*/1 * * * * runuser php5 \
--command="/var/www/web/includes/crontab/queue_process.php \
>> /var/www/web/includes/crontab/queue.log 2>&1"
See also: man runuser
Try,
# cat test.sh
#!/bin/bash
/bin/touch file.txt
cron as:
* * * * * /bin/sh /home/myUser/scripts/test.sh
And you can confirm this by:
# tailf /var/log/cron
You just need to open pg_hba.conf and sets trust in all methods. That's works for me. Therefore the security is null.
When specifying your cron values you'll need to make sure that your values fall within the ranges. For instance, some cron's use a 0-7 range for the day of week where both 0 and 7 represent Sunday. We do not(check below).
Seconds: 0-59
Minutes: 0-59
Hours: 0-23
Day of Month: 1-31
Months: 0-11
Day of Week: 0-6

I tried @ScottK's approach, first as a side feature of my functional UDF, then as a standalone _Help suffix version when I ran into trouble (see below). In hindsight, the latter approach is better anyway--more obvious to a user attentive enough to see a tool tip, and it doesn't clutter up the functional code.
I figured if an inattentive user just typed the function name and closed the parentheses while he thought it over, help would appear and he would be on his way. But dumping a bunch of text into a single cell that I cannot format didn't seem like a good idea. Instead, When the function is entered in a cell with no arguments i.e.
= interpolateLinear()
or
= interpolateLinear_Help()
a msgBox opens with the help text. A msgBox is limited to ~1000 characters, maybe it's 1024. But that's enough (barely 8^/) for my overly tricked out interpolation function. If it's not, you can always open a user form and go to town.
The first time the message box opened, it looked like success. But there are a couple of problems. First of course, the user has to know to enter the function with no arguments (+1 for the _Help suffix UDF).
The big problem is, the msgBox reopens several times in succession, spontaneously while working in unrelated parts of the workbook. Needless to say, it's very annoying. Sometimes it goes on until I get a circular reference warning. Go figure. If a UDF could change the cell formula, I would have done that to shut it up.
I don't know why Excel feels the need recalculate the formula over and over; neither the _Help standalone, nor the full up version (in help mode) has precedents or dependents. There's not an application.volatile statement anywhere. Of course the function returns a value to the calling cell. Maybe that triggers the recalc? But that's what UDFs do. I don't think you can not return a value.
Since you can't modify a worksheet formula from a UDF, I tried to return a specific string --a value --to the calling cell (the only one you can change the value of from a UDF), figuring I would inspect the cell value using application.caller on the next cycle, spot my string, and know not to re-display the help message. Seemed like a good idea at the time--didn't work. Maybe I did something stupid in my sleep-deprived state. I still like the idea. I'll update this when (if) I fix the problem. My quick fix was to add a line on the help box: "Seek help only in an emergency. Delete the offending formula to end the misery.
In the meantime, I tried the Application.MacroOptions approach. Pretty easy, and it looks professional. Just one problem to work out. I'll post a separate answer on that approach later.
It was almost correct just change your last line like:
String stopEnd = stop.substring(0, stop.length() - 1); //replace stopName with stop.
OR
you can replace your last two lines;
String stopEnd = stopName.substring(0, stopName.length() - 2);
Okay, so I've joined the google group of libphonenumber ( https://groups.google.com/forum/?hl=en&fromgroups#!forum/libphonenumber-discuss ) and I've asked a question.
I don't need to set the country in parameter if my phone number begins with "+". Here is an example :
PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
// phone must begin with '+'
PhoneNumber numberProto = phoneUtil.parse(phone, "");
int countryCode = numberProto.getCountryCode();
} catch (NumberParseException e) {
System.err.println("NumberParseException was thrown: " + e.toString());
}
From my Diceshaker application:
// Ensures the shake is strong enough on at least two axes before declaring it a shake.
// "Strong enough" means "greater than a client-supplied threshold" in G's.
static BOOL L0AccelerationIsShaking(UIAcceleration* last, UIAcceleration* current, double threshold) {
double
deltaX = fabs(last.x - current.x),
deltaY = fabs(last.y - current.y),
deltaZ = fabs(last.z - current.z);
return
(deltaX > threshold && deltaY > threshold) ||
(deltaX > threshold && deltaZ > threshold) ||
(deltaY > threshold && deltaZ > threshold);
}
@interface L0AppDelegate : NSObject <UIApplicationDelegate> {
BOOL histeresisExcited;
UIAcceleration* lastAcceleration;
}
@property(retain) UIAcceleration* lastAcceleration;
@end
@implementation L0AppDelegate
- (void)applicationDidFinishLaunching:(UIApplication *)application {
[UIAccelerometer sharedAccelerometer].delegate = self;
}
- (void) accelerometer:(UIAccelerometer *)accelerometer didAccelerate:(UIAcceleration *)acceleration {
if (self.lastAcceleration) {
if (!histeresisExcited && L0AccelerationIsShaking(self.lastAcceleration, acceleration, 0.7)) {
histeresisExcited = YES;
/* SHAKE DETECTED. DO HERE WHAT YOU WANT. */
} else if (histeresisExcited && !L0AccelerationIsShaking(self.lastAcceleration, acceleration, 0.2)) {
histeresisExcited = NO;
}
}
self.lastAcceleration = acceleration;
}
// and proper @synthesize and -dealloc boilerplate code
@end
The histeresis prevents the shake event from triggering multiple times until the user stops the shake.
I want to add that when using Npgsql (data provider for PostgreSQL), arrays and lists of primitive types are actually supported:
Use the -S (note: capital S) switch to GCC, and it will emit the assembly code to a file with a .s extension. For example, the following command:
gcc -O2 -S foo.c
will leave the generated assembly code on the file foo.s.

Hey this is pretty simple to solve this error.Just follow this steps:
First uninstall any existing installation:
pip uninstall scikit-image
or, on conda-based systems:
conda uninstall scikit-image
Now, clone scikit-image on your local computer, and install:
git clone https://github.com/scikit-image/scikit-image.git
cd scikit-image
pip install -e .
To update the installation:
git pull # Grab latest source
pip install -e . # Reinstall
For other os and manual process please check this Link.
Luckily, it’s very easy to resolve. Run the follow command from an elevated command prompt:
%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i
If you’re on a 32-bit machine, you may have to use the following:
%windir%\Microsoft.NET\Framework\v4.0.30319\aspnet_regiis.exe -i
Similar solution but much cleaner to use

Yes, a table row can slide up and down, but it's ugly, since it changes the shape of the table and makes everything jump. Instead, put and element in each td
... something that makes sense like a p
or h2
etc.
For how to implement a table slide toggle...
It's probably simplest to put the click handler on the entire table, .stopPropagation()
and check what was clicked.
If a td in a row with a colspan is clicked, close the p
in it. If it's not a td in a row with a colspan, then close then toggle the following row's p
.
It is essentially to wrap all your written content in an element inside the td
s, since you never want to slideUp
a td
or tr
or table shape will change!
Something like:
$(function() {
// Initially hide toggleable content
$("td[colspan=3]").find("p").hide();
// Click handler on entire table
$("table").click(function(event) {
// No bubbling up
event.stopPropagation();
var $target = $(event.target);
// Open and close the appropriate thing
if ( $target.closest("td").attr("colspan") > 1 ) {
$target.slideUp();
} else {
$target.closest("tr").next().find("p").slideToggle();
}
});
});?
... and try out this jsFiddle showing implementation of a +
- -
toggle.
The HTML just has to have alternating rows of several td
s and then a row with a td
of a colspan greater than 1. You can obviously adjust the specifics quite easily.
The HTML would look something like:
<table>
<tr><td><p>Name</p></td><td><p>Age</p></td><td><p>Info</p></td></tr>
<tr><td colspan="3"><p>Blah blah blah blah blah blah blah.</p>
</td></tr>
<tr><td><p>Name</p></td><td><p>Age</p></td><td><p>Info</p></td></tr>
<tr><td colspan="3"><p>Blah blah blah blah blah blah blah.</p>
</td></tr>
<tr><td><p>Name</p></td><td><p>Age</p></td><td><p>Info</p></td></tr>
<tr><td colspan="3"><p>Blah blah blah blah blah blah blah.</p>
</td></tr>
</table>?
In my case I had to remove the android platform and add it again. Something got stuck and copying all my code into another app worked like a charm - hence my idea of cleaning up the build for android by removing the platform.
cordova platform remove android
cordova platform add android
I guess it's some kind of cleanup that you have to do from time to time :-(
I think you are saying that a container
vs container-fluid
is the difference between responsive and non-responsive to the grid. This is not true...what is saying is that the width is not fixed...its full width!
This is hard to explain so lets look at the examples
Example one
container-fluid
:
So you see how the container takes up the whole screen...that's a container-fluid
.
Now lets look at the other just a normal container
and watch the edges of the preview
Example two
container
Now do you see the white space in the example? That's because its a fixed width container
! It might make more sense to open both examples up in two different tabs and switch back and forth.
EDIT
Better yet here is an example with both containers at once! Now you can really tell the difference!
I hope this helped clarify a little bit!
Yes we can check the length of queue object created from collections.
from collections import deque
class Queue():
def __init__(self,batchSize=32):
#self.batchSie = batchSize
self._queue = deque(maxlen=batchSize)
def enqueue(self, items):
''' Appending the items to the queue'''
self._queue.append(items)
def dequeue(self):
'''remoe the items from the top if the queue becomes full '''
return self._queue.popleft()
Creating an object of class
q = Queue(batchSize=64)
q.enqueue([1,2])
q.enqueue([2,3])
q.enqueue([1,4])
q.enqueue([1,22])
Now retrieving the length of the queue
#check the len of queue
print(len(q._queue))
#you can print the content of the queue
print(q._queue)
#Can check the content of the queue
print(q.dequeue())
#Check the length of retrieved item
print(len(q.dequeue()))
check the results in attached screen shot
Hope this helps...
if anyone needs to extract the first part of the string then can try,
Query:
$s = "This_is_a_string_233718";
$text = $s."_".substr($s, 0, strrpos($s, "_"));
Output:
This_is_a_string
With SQLServer 2005 Express, what I found was that even with autocommit off, insertions into a Db table were committed without my actually issuing a commit command from the Management Studio session. The only difference was, when autocommit was off, I could roll back all the insertions; with *autocommit on, I could not.* Actually, I was wrong. With autocommit mode off, I see the changes only in the QA (Query Analyzer) window from which the commands were issued. If I popped a new QA (Query Analyzer) window, I do not see the changes made by the first window (session), i.e. they are NOT committed! I had to issue explicit commit or rollback commands to make changes visible to other sessions(QA windows) -- my bad! Things are working correctly.
is this what you want?
var grouped = CustomerList.GroupBy(m => m.GroupID).Select((n) => new { GroupId = n.Key, Items = n.ToList() });

Look at http://github.com/mono/mono/tree/master/mcs/class/Mono.Options/
Except when it is the operand of the sizeof
or unary &
operator, or is a string literal being used to initialize another array in a declaration, an expression of type "N-element array of T
" is converted ("decays") to an expression of type "pointer to T
", and the value of the expression is the address of the first element of the array.
If the declaration of the array being passed is
int S[4][4] = {...};
then when you write
rotateArr( S );
the expression S
has type "4-element array of 4-element array of int
"; since S
is not the operand of the sizeof
or unary &
operators, it will be converted to an expression of type "pointer to 4-element array of int
", or int (*)[4]
, and this pointer value is what actually gets passed to rotateArr
. So your function prototype needs to be one of the following:
T rotateArr( int (*arr)[4] )
or
T rotateArr( int arr[][4] )
or even
T rotateArr( int arr[4][4] )
In the context of a function parameter list, declarations of the form T a[N]
and T a[]
are interpreted as T *a
; all three declare a
as a pointer to T
.
You're probably wondering why I changed the return type from int
to T
. As written, you're trying to return a value of type "4-element array of 4-element array of int
"; unfortunately, you can't do that. C functions cannot return array types, nor can you assign array types. IOW, you can't write something like:
int a[N], b[N];
...
b = a; // not allowed
a = f(); // not allowed either
Functions can return pointers to arrays, but that's not what you want here. D
will cease to exist once the function returns, so any pointer you return will be invalid.
If you want to assign the results of the rotated array to a different array, then you'll have to pass the target array as a parameter to the function:
void rotateArr( int (*dst)[4], int (*src)[4] )
{
...
dst[i][n] = src[n][M - i + 1];
...
}
And call it as
int S[4][4] = {...};
int D[4][4];
rotateArr( D, S );

Use the git commit
command without any flags. The configured editor will open (Vim in this case):
To start typing press the INSERT key on your keyboard, then in insert mode create a better commit with description how do you want. For example:
Once you have written all that you need, to returns to git, first you should exit insert mode, for that press ESC. Now close the Vim editor with save changes by typing on the keyboard :wq
(w - write, q - quit):
and press ENTER.
On GitHub this commit will looks like this:
As a commit editor you can use VS Code:

Similar to the Ubuntu answer above, the Windows admin default password is stored in {jenkins install dir}\secrets\initialAdminPassword file (default install location would it in C:\Program Files (x86)\Jenkins\secrets\initialAdminPassword )

I find it easier to implement it in the XML file as it can be harder to trace the line of code in a class with hundreds of lines. For the XML you can use "null":
android:divider="@null"
You can also delete the branch on the remote directly. Having done that, the next update will remove it from your working copy.
svn rm "^/reponame/branches/name_of_branch" -m "cleaning up old branch name_of_branch"
The ^
is short for the URL of the remote, as seen in 'svn info'. The double quotes are necessary on Windows command line, because ^
is a special character.
This command will also work if you have never checked out the branch.
We can add Unique key index by using fluent api. Below code worked for me
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<User>().Property(p => p.Email).HasColumnAnnotation("Index", new IndexAnnotation(new IndexAttribute("IX_EmailIndex") { IsUnique = true }));
}
Just a word on drawing (incorrect) conclusions from any of the performance measurement commands referred to in the answers. There are a number of pitfalls that should taken in consideration aside from looking to the bare invocation time of a (custom) function or command.
'Sjoemelsoftware' voted Dutch word of the year 2015
Sjoemelen means cheating, and the word sjoemelsoftware came into being due to the Volkswagen emissions scandal. The official definition is "software used to influence test results".
Personally, I think that "Sjoemelsoftware" is not always deliberately created to cheat test results but might originate from accommodating practical situation that are similar to test cases as shown below.
As an example, using the listed performance measurement commands, Language Integrated Query (LINQ)(1), is often qualified as the fasted way to get something done and it often is, but certainly not always! Anybody who measures a speed increase of a factor 40 or more in comparison with native PowerShell commands, is probably incorrectly measuring or drawing an incorrect conclusion.
The point is that some .Net classes (like LINQ) using a lazy evaluation (also referred to as deferred execution(2)). Meaning that when assign an expression to a variable, it almost immediately appears to be done but in fact it didn't process anything yet!
Let presume that you dot-source your . .\Dosomething.ps1
command which has either a PowerShell or a more sophisticated Linq expression (for the ease of explanation, I have directly embedded the expressions directly into the Measure-Command
):
$Data = @(1..100000).ForEach{[PSCustomObject]@{Index=$_;Property=(Get-Random)}}
(Measure-Command {
$PowerShell = $Data.Where{$_.Index -eq 12345}
}).totalmilliseconds
864.5237
(Measure-Command {
$Linq = [Linq.Enumerable]::Where($Data, [Func[object,bool]] { param($Item); Return $Item.Index -eq 12345})
}).totalmilliseconds
24.5949
The result appears obvious, the later Linq command is a about 40 times faster than the first PowerShell command. Unfortunately, it is not that simple...
Let's display the results:
PS C:\> $PowerShell
Index Property
----- --------
12345 104123841
PS C:\> $Linq
Index Property
----- --------
12345 104123841
As expected, the results are the same but if you have paid close attention, you will have noticed that it took a lot longer to display the $Linq
results then the $PowerShell
results.
Let's specifically measure that by just retrieving a property of the resulted object:
PS C:\> (Measure-Command {$PowerShell.Property}).totalmilliseconds
14.8798
PS C:\> (Measure-Command {$Linq.Property}).totalmilliseconds
1360.9435
It took about a factor 90 longer to retrieve a property of the $Linq
object then the $PowerShell
object and that was just a single object!
Also notice an other pitfall that if you do it again, certain steps might appear a lot faster then before, this is because some of the expressions have been cached.
Bottom line, if you want to compare the performance between two functions, you will need to implement them in your used case, start with a fresh PowerShell session and base your conclusion on the actual performance of the complete solution.
(1) For more background and examples on PowerShell and LINQ, I recommend tihis site: High Performance PowerShell with LINQ
(2) I think there is a minor difference between the two concepts as with lazy evaluation the result is calculated when needed as apposed to deferred execution were the result is calculated when the system is idle
You dont need to use a regex for this, PHP has an inbuilt function ctype_alnum
which will do this for you, and execute faster:

$strings = array('AbCd1zyZ9', 'foo!#$bar');
foreach ($strings as $testcase) {
if (ctype_alnum($testcase)) {
echo "The string $testcase consists of all letters or digits.\n";
} else {
echo "The string $testcase does not consist of all letters or digits.\n";
}
}
?>
If you desperately want to use a regex, you have a few options.
Firstly:
preg_match('/^[\w]+$/', $string);
\w
includes more than alphanumeric (it includes underscore), but includes all
of \d
.
Alternatively:
/^[a-zA-Z\d]+$/
Or even just:
/^[^\W_]+$/
What I would do is use the same trick often use for hovering on buttons. Prepare an image that has 2 parts: (1) a top half which is greyed out, meaning incomplete, and (2) a bottom half which is colored in, meaning completed. Use the same image 4 times to make up the 4 steps of the progress bar, and align top for incomplete steps, and align bottom for incomplete steps.
In order to take advantage of image alignment, you'd have to use the image as the background for 4 divs, rather than using the img element.
This is the CSS for background image alignment:
div.progress-incomplete {
background-position: top;
}
div.progress-finished {
background-position: bottom;
}
On Webpack 2 I tried all 12 devtool options. The following options link to the original file in the console and preserve line numbers. See the note below re: lines only.

Source Maps are simplified to a single mapping per line. This usually means a single mapping per statement (assuming you author is this way). This prevents you from debugging execution on statement level and from settings breakpoints on columns of a line. Combining with minimizing is not possible as minimizers usually only emit a single line.
REVISITING THIS
On a large project I find ... eval-source-map rebuild time is ~3.5s ... inline-source-map rebuild time is ~7s
Mongo DB requires space to store it files. So you should create folder structure for Mongo DB before starting the Mongodb server/client.
for e.g. MongoDb/Dbfiles where Mongo DB is installed.
Then in cmd promt exe mongod.exe and mongo.exe for client and done.

The simplest (and hence best) C++ (using the 2011 standard) answer is
#include <random>
std::random_device rd; // only used once to initialise (seed) engine
std::mt19937 rng(rd()); // random-number engine used (Mersenne-Twister in this case)
std::uniform_int_distribution<int> uni(min,max); // guaranteed unbiased
auto random_integer = uni(rng);
No need to re-invent the wheel. No need to worry about bias. No need to worry about using time as random seed.
Linux: You can use this command if you know the port :
netstat -plten | grep LISTEN | grep 8080
AIX:
netstat -Aan | grep LISTEN | grep 8080
You then take the first column (example: f100050000b05bb8) and run the following command:
rmsock f100050000b05bb8 tcpcb
kill process.
Here is how I transitioned from UIWebView to WKWebView.
Note: There is no property like UIWebView that you can drag onto your storyboard, you have to do it programatically.
Make sure you import WebKit/WebKit.h into your header file.
This is my header file:
#import <WebKit/WebKit.h>
@interface ViewController : UIViewController
@property(strong,nonatomic) WKWebView *webView;
@property (strong, nonatomic) NSString *productURL;
@end
Here is my implementation file:
#import "ViewController.h"
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.productURL = @"http://www.URL YOU WANT TO VIEW GOES HERE";
NSURL *url = [NSURL URLWithString:self.productURL];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
_webView = [[WKWebView alloc] initWithFrame:self.view.frame];
[_webView loadRequest:request];
_webView.frame = CGRectMake(self.view.frame.origin.x,self.view.frame.origin.y, self.view.frame.size.width, self.view.frame.size.height);
[self.view addSubview:_webView];
}

Assuming Java (JDK + JRE) is installed in your system, do the following:

You have to use either DQL or the QueryBuilder. E.g. in your Purchase-EntityRepository you could do something like this:
$q = $this->createQueryBuilder('p')
->where('p.prize > :purchasePrize')
->setParameter('purchasePrize', 200)
->getQuery();
$q->getResult();
For even more complex scenarios take a look at the Expr() class.
Your first problem is that you are passing -3 to the 2nd parameter of Columns.Add. It needs to be -2 for it to auto-size the column. Source: http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.columns.aspx (look at the comments on the code example at the bottom)
private void initListView()
{
// Add columns
lvRegAnimals.Columns.Add("Id", -2,HorizontalAlignment.Left);
lvRegAnimals.Columns.Add("Name", -2, HorizontalAlignment.Left);
lvRegAnimals.Columns.Add("Age", -2, HorizontalAlignment.Left);
}
You can also use the other overload, Add(string). E.g:
lvRegAnimals.Columns.Add("Id");
lvRegAnimals.Columns.Add("Name");
lvRegAnimals.Columns.Add("Age");
Reference for more overloads: http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.columnheadercollection.aspx
Second, to add items to the ListView, you need to create instances of ListViewItem and add them to the listView's Items collection. You will need to use the string[] constructor.
var item1 = new ListViewItem(new[] {"id123", "Tom", "24"});
var item2 = new ListViewItem(new[] {person.Id, person.Name, person.Age});
lvRegAnimals.Items.Add(item1);
lvRegAnimals.Items.Add(item2);
You can also store objects in the item's Tag property.
item2.Tag = person;
And then you can extract it
var person = item2.Tag as Person;
Let me know if you have any questions and I hope this helps!
jQuery is up in here, so:
jQuery.fn.goodOLauterHTML= function() {
return $('<a></a>').append( this.clone() ).html();
}
Return all that HTML stuff:
$('div' /*elys with HTML text stuff that you want */ ).goodOLauterHTML(); // alerts tags and all
if you just want to round a number or a list, simply use
round(data, 2)
Then, data will be round to 2 decimal place.
To access the raw RGB values of an UIImage in Swift 5 use the underlying CGImage and its dataProvider:
import UIKit
let image = UIImage(named: "example.png")!
guard let cgImage = image.cgImage,
let data = cgImage.dataProvider?.data,
let bytes = CFDataGetBytePtr(data) else {
fatalError("Couldn't access image data")
}
assert(cgImage.colorSpace?.model == .rgb)
let bytesPerPixel = cgImage.bitsPerPixel / cgImage.bitsPerComponent
for y in 0 ..< cgImage.height {
for x in 0 ..< cgImage.width {
let offset = (y * cgImage.bytesPerRow) + (x * bytesPerPixel)
let components = (r: bytes[offset], g: bytes[offset + 1], b: bytes[offset + 2])
print("[x:\(x), y:\(y)] \(components)")
}
print("---")
}

Here, the '\n'
left by cin, is creating issues.
do {
system("cls");
manageCustomerMenu();
cin >> choice; #This cin is leaving a trailing \n
system("cls");
switch (choice) {
case '1':
createNewCustomer();
break;
This \n
is being consumed by next getline in createNewCustomer()
. You should use getline instead -
do {
system("cls");
manageCustomerMenu();
getline(cin, choice)
system("cls");
switch (choice) {
case '1':
createNewCustomer();
break;
I think this would resolve the issue.
As a non-java selenium user, here is the python equivalent to Margus's answer:

def setUp(self, ):
desired = DesiredCapabilities.CHROME
desired ['loggingPrefs'] = { 'browser':'ALL' }
self.driver = webdriver.Chrome(desired_capabilities=desired)
def analyzeLog(self, ):
data = self.driver.get_log('browser')
print(data)
def testMethod(self, ):
self.setUp()
self.driver.get("http://mypage.com")
self.analyzeLog()

Click on the Supporting Files group(left side top - name of your project). Navigate to Info. Click on + somewhere between lists, like below bundle name. And add "View controller-based status bar appearence" and set it to NO. Then open AppDelegate.swift and modify like this:

UIApplication.sharedApplication().setStatusBarStyle(UIStatusBarStyle.LightContent, animated: true)
return true
}
Thats it.
Advantages of a PreparedStatement
:
Precompilation and DB-side caching of the SQL statement leads to overall faster execution and the ability to reuse the same SQL statement in batches.
Automatic prevention of SQL injection attacks by builtin escaping of quotes and other special characters. Note that this requires that you use any of the PreparedStatement
setXxx()
methods to set the values
preparedStatement = connection.prepareStatement("INSERT INTO Person (name, email, birthdate, photo) VALUES (?, ?, ?, ?)");
preparedStatement.setString(1, person.getName());
preparedStatement.setString(2, person.getEmail());
preparedStatement.setTimestamp(3, new Timestamp(person.getBirthdate().getTime()));
preparedStatement.setBinaryStream(4, person.getPhoto());
preparedStatement.executeUpdate();
and thus don't inline the values in the SQL string by string-concatenating.
preparedStatement = connection.prepareStatement("INSERT INTO Person (name, email) VALUES ('" + person.getName() + "', '" + person.getEmail() + "'");
preparedStatement.executeUpdate();
Eases setting of non-standard Java objects in a SQL string, e.g. Date
, Time
, Timestamp
, BigDecimal
, InputStream
(Blob
) and Reader
(Clob
). On most of those types you can't "just" do a toString()
as you would do in a simple Statement
. You could even refactor it all to using PreparedStatement#setObject()
inside a loop as demonstrated in the utility method below:
public static void setValues(PreparedStatement preparedStatement, Object... values) throws SQLException {
for (int i = 0; i < values.length; i++) {
preparedStatement.setObject(i + 1, values[i]);
}
}
Which can be used as below:
preparedStatement = connection.prepareStatement("INSERT INTO Person (name, email, birthdate, photo) VALUES (?, ?, ?, ?)");
setValues(preparedStatement, person.getName(), person.getEmail(), new Timestamp(person.getBirthdate().getTime()), person.getPhoto());
preparedStatement.executeUpdate();
You could try to assign properties to the ENUM you're trying to create and statically contruct it by using a loaded properties file. Big hack, but it works :)

A bit late in the game, i know... but this is what i recently did. It is slightly different than yours, but allows the programmer to dictate what the equality operation needs to be (predicate). Which i find very useful when dealing with different types, since i then have a generic way of doing it regardless of object type and <T>
built in equality operator.
It also has a very very small memory footprint, and is very, very fast/efficient... if you care about that.
At worse, you'll just add this to your list of extensions.
Anyway... here it is.
public static int IndexOf<T>(this IEnumerable<T> source, Func<T, bool> predicate)
{
int retval = -1;
var enumerator = source.GetEnumerator();
while (enumerator.MoveNext())
{
retval += 1;
if (predicate(enumerator.Current))
{
IDisposable disposable = enumerator as System.IDisposable;
if (disposable != null) disposable.Dispose();
return retval;
}
}
IDisposable disposable = enumerator as System.IDisposable;
if (disposable != null) disposable.Dispose();
return -1;
}
Hopefully this helps someone.
If the server is started on the same terminal, then it's the server's stderr that is presumably being written to the terminal and which you are not capturing.
The best way to capture everything would be to run:
script output.txt
before starting up either the server or the client. This will launch a new shell with all terminal output redirected out output.txt as well as the terminal. Then start the server from within that new shell, and then the client. Everything that you see on the screen (both your input and the output of everything writing to the terminal from within that shell) will be written to the file.
When you are done, type "exit" to exit the shell run by the script
command.
You can use the ThenBy and ThenByDescending extension methods:
foobarList.OrderBy(x => x.Foo).ThenBy( x => x.Bar)
To set an existing column right/left of another, based on their names:
def df_move_column(df, col_to_move, col_left_of_destiny="", right_of_col_bool=True):
cols = list(df.columns.values)
index_max = len(cols) - 1
if not right_of_col_bool:
# set left of a column "c", is like putting right of column previous to "c"
# ... except if left of 1st column, then recursive call to set rest right to it
aux = cols.index(col_left_of_destiny)
if not aux:
for g in [x for x in cols[::-1] if x != col_to_move]:
df = df_move_column(
df,
col_to_move=g,
col_left_of_destiny=col_to_move
)
return df
col_left_of_destiny = cols[aux - 1]
index_old = cols.index(col_to_move)
index_new = 0
if len(col_left_of_destiny):
index_new = cols.index(col_left_of_destiny) + 1
if index_old == index_new:
return df
if index_new < index_old:
index_new = np.min([index_new, index_max])
cols = (
cols[:index_new]
+ [cols[index_old]]
+ cols[index_new:index_old]
+ cols[index_old + 1 :]
)
else:
cols = (
cols[:index_old]
+ cols[index_old + 1 : index_new]
+ [cols[index_old]]
+ cols[index_new:]
)
df = df[cols]
return df
E.g.
cols = list("ABCD")
df2 = pd.DataFrame(np.arange(4)[np.newaxis, :], columns=cols)
for k in cols:
print(30 * "-")
for g in [x for x in cols if x != k]:
df_new = df_move_column(df2, k, g)
print(f"{k} after {g}: {df_new.columns.values}")
for k in cols:
print(30 * "-")
for g in [x for x in cols if x != k]:
df_new = df_move_column(df2, k, g, right_of_col_bool=False)
print(f"{k} before {g}: {df_new.columns.values}")
Output:
This might work:
^(\*|\d+(\.\d+){0,2}(\.\*)?)$
At the top level, "*" is a special case of a valid version number. Otherwise, it starts with a number. Then there are zero, one, or two ".nn" sequences, followed by an optional ".*". This regex would accept 1.2.3.* which may or may not be permitted in your application.
The code for retrieving the matched sequences, especially the (\.\d+){0,2}
part, will depend on your particular regex library.
In String type we have several method valueOf
static String valueOf(boolean b)
static String valueOf(char c)
static String valueOf(char[] data)
static String valueOf(char[] data, int offset, int count)
static String valueOf(double d)
static String valueOf(float f)
static String valueOf(int i)
static String valueOf(long l)
static String valueOf(Object obj)
As we can see those method are capable to resolve all kind of numbers
every implementation of specific method like you have presented: So for integers we have
Integer.toString(int i)
for double
Double.toString(double d)
and so on
In my opinion this is not some historical thing, but it is more useful for a developer to use the method valueOf
from the String class than from the proper type, as it leads to fewer changes for us to make.
Sample 1:
public String doStuff(int num) {
// Do something with num...
return String.valueOf(num);
}
Sample2:
public String doStuff(int num) {
// Do something with num...
return Integer.toString(num);
}
As we see in sample 2 we have to do two changes, in contrary to sample one.
In my conclusion, using the valueOf
method from String class is more flexible and that's why it is available there.
Have a look at Schema and Data Comparison tools in dbForge Studio for MySQL. These tool will help you to compare, to see the differences, generate a synchronization script and synchronize two databases.

Select * from Table1 left join Table2 ...
and
Select * from Table2 right join Table1 ...
are indeed completely interchangeable. Try however Table2 left join Table1
(or its identical pair, Table1 right join Table2
) to see a difference. This query should give you more rows, since Table2 contains a row with an id which is not present in Table1.
I was trying to to the same, I found lots of information on reading .docx but much less on .doc; Anyway, I managed to read the text using the following:

Use .onkeydown
and cancel the removing with return false;
. Like this:
var input = document.getElementById('myInput');
input.onkeydown = function() {
var key = event.keyCode || event.charCode;
if( key == 8 || key == 46 )
return false;
};
Or with jQuery, because you added a jQuery tag to your question:
jQuery(function($) {
var input = $('#myInput');
input.on('keydown', function() {
var key = event.keyCode || event.charCode;
if( key == 8 || key == 46 )
return false;
});
});

print(unFld(lst))
Output :
1 on

press any key to exit
the best way is using the base::function as say @sth
if ( condition ) {
return;
}
The return
exits the function returning undefined
.
The exit
statement doesn't exist in javascript.
The break
statement allows you to exit a loop, not a function. For example:
var i = 0;
while ( i < 10 ) {
i++;
if ( i === 5 ) {
break;
}
}
This also works with the for
and the switch
loops.
My answer is similar but different, there are a few ways to achieve toggling effect. I guess it depends on your circumstance. This may not be the best way for you in the end.
The missing piece you've been looking for is to create an if
statement. This allows for you to toggle your text.
JSFiddle: http://jsfiddle.net/8u2jF/
Javascript:
var status = "less";
function toggleText()
{
var text="Here is some text that I want added to the HTML file";
if (status == "less") {
document.getElementById("textArea").innerHTML=text;
document.getElementById("toggleButton").innerText = "See Less";
status = "more";
} else if (status == "more") {
document.getElementById("textArea").innerHTML = "";
document.getElementById("toggleButton").innerText = "See More";
status = "less"
}
}
For Schema related stuff
Model.column_names
Model.columns_hash
Model.columns
For instance variables/attributes in an AR object
object.attribute_names
object.attribute_present?
object.attributes
For instance methods without inheritance from super class
Model.instance_methods(false)
Upon investigation, it's also worth noting that when you want to start using docker in a new terminal window, the correct command is:

I know this has been answered, but TypeScript introduced type guards: https://www.typescriptlang.org/docs/handbook/advanced-types.html#typeof-type-guards
If you have a type like: Object[] | string[]
and what to do something conditionally based on what type it is - you can use this type guarding:
function isStringArray(value: any): value is string[] {
if (value instanceof Array) {
value.forEach(function(item) { // maybe only check first value?
if (typeof item !== 'string') {
return false
}
})
return true
}
return false
}
function join<T>(value: string[] | T[]) {
if (isStringArray(value)) {
return value.join(',') // value is string[] here
} else {
return value.map((x) => x.toString()).join(',') // value is T[] here
}
}
There is an issue with an empty array being typed as string[]
, but that might be okay
Regardless of following a naming convention that avoids using reserved words, Microsoft does add new reserved words. Using brackets allows your code to be upgraded to a new SQL Server version, without first needing to edit Microsoft's newly reserved words out of your client code. That editing can be a significant concern. It may cause your project to be prematurely retired....
Brackets can also be useful when you want to Replace All in a script. If your batch contains a variable named @String and a column named [String], you can rename the column to [NewString], without renaming @String to @NewString.
URL yahoo = new URL("http://www.yahoo.com/");
BufferedReader in = new BufferedReader(

System.out.println(inputLine);
in.close();
You could use a nested Any()
for this check which is available on any Enumerable
:
bool hasMatch = myStrings.Any(x => parameters.Any(y => y.source == x));
Faster performing on larger collections would be to project parameters
to source
and then use Intersect
which internally uses a HashSet<T>
so instead of O(n^2) for the first approach (the equivalent of two nested loops) you can do the check in O(n) :
bool hasMatch = parameters.Select(x => x.source)
.Intersect(myStrings)
.Any();
Also as a side comment you should capitalize your class names and property names to conform with the C# style guidelines.
In your code, you can find this function:
// Update a particular HTML element with a new value
function updateHTML(elmId, value) {
document.getElementById(elmId).innerHTML = value;
}
Later on, you call this function with several params:
updateHTML("videoCurrentTime", secondsToHms(ytplayer.getCurrentTime())+' /');
updateHTML("videoDuration", secondsToHms(ytplayer.getDuration()));
updateHTML("bytesTotal", ytplayer.getVideoBytesTotal());
updateHTML("startBytes", ytplayer.getVideoStartBytes());
updateHTML("bytesLoaded", ytplayer.getVideoBytesLoaded());
updateHTML("volume", ytplayer.getVolume());
The first param is used for the "getElementById", but the elements with ID "bytesTotal", "startBytes", "bytesLoaded" and "volume" don't exist. You'll need to create them, since they'll return null.
With IE 10 I resolved the problem with :
var file = document.getElementById("file-input");
file.removeAttribute('value');
file.parentNode.replaceChild(file.cloneNode(true),file);
where :
<input accept="image/*" onchange="angular.element(this).scope().uploadFile(this)" id="file-input" type="file"/>
Use percent-encoded form. Some (mainly old) computers running Windows XP for example do not support Unicode, but rather ISO encodings. That is the reason percent-encoded URLs were invented. Also, if you give a URL printed on paper to a user, containing characters that cannot be easily typed, that user may have a hard time typing it (or just ignore it). Percent-encoded form can even be used in many of the oldest machines that ever existed (although they don't support internet of course).
There is a downside though, as percent-encoded characters are longer than the original ones, thus possibly resulting in really long URLs. But just try to ignore it, or use a URL shortener (I would recommend goo.gl in this case, which makes a 13-character long URL). Also, if you don't want to register for a Google account, try bit.ly (bit.ly makes slightly longer URLs, with the length being 14 characters).
For lists, use enumerate
for field, possible_values in enumerate(fields):
print(field, possible_values)
iteritems
will not work for list objects
ORA-06512 is part of the error stack. It gives us the line number where the exception occurred, but not the cause of the exception. That is usually indicated in the rest of the stack (which you have still not posted).
In a comment you said
"still, the error comes when pNum is not between 12 and 14; when pNum is between 12 and 14 it does not fail"
Well, your code does this:
IF ((pNum < 12) OR (pNum > 14)) THEN
RAISE vSOME_EX;
That is, it raises an exception when pNum is not between 12 and 14. So does the rest of the error stack include this line?
ORA-06510: PL/SQL: unhandled user-defined exception
If so, all you need to do is add an exception block to handle the error. Perhaps:
PROCEDURE PX(pNum INT,pIdM INT,pCv VARCHAR2,pSup FLOAT)
AS
vSOME_EX EXCEPTION;
BEGIN
IF ((pNum < 12) OR (pNum > 14)) THEN
RAISE vSOME_EX;
ELSE
EXECUTE IMMEDIATE 'INSERT INTO M'||pNum||'GR (CV, SUP, IDM'||pNum||') VALUES('||pCv||', '||pSup||', '||pIdM||')';
END IF;
exception
when vsome_ex then
raise_application_error(-20000
, 'This is not a valid table: M'||pNum||'GR');
END PX;
The documentation covers handling PL/SQL exceptions in depth.
Just put
echo "<link rel='stylesheet' type='text/css' href='CSS/main.css'>";
inside the php code, then your style is incuded. Worked for me, I tried.
To update, you can install n
sudo npm install -g n
Then just :
sudo n latest
or a specific version
sudo n 8.9.0
this.state.myArray.push('new value')
returns the length of the extended array, instead of the array itself.Array.prototype.push().
I guess you expect the returned value to be the array.
It seems it's rather the behaviour of React:
NEVER mutate this.state directly, as calling setState() afterwards may replace the mutation you made. Treat this.state as if it were immutable.React.Component.
I guess, you would do it like this (not familiar with React):
var joined = this.state.myArray.concat('new value');
this.setState({ myArray: joined })
You need formulas to convert latitude and longitude to rectangular coordinates. There are a great number to choose from and each will distort the map in a different way. Wolfram MathWorld has a good collection:

To search all the words with start with "icon-" the following command works perfect. I am using Ack here which is similar to grep but with better options and nice formatting.

This usually occurs when your current directory does not exist anymore. Most likely, from another terminal you remove that directory (from within a script or whatever). To get rid of this, in case your current directory was recreated in the meantime, just cd
to another (existing) directory and then cd
back; the simplest would be: cd; cd -
.
this code will work with OI File Manager :
File root = new File(Environment.getExternalStorageDirectory().getPath()
+ "/myFolder/");
Uri uri = Uri.fromFile(root);
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setData(uri);
startActivityForResult(intent, 1);
you can get OI File manager here : http://www.openintents.org/en/filemanager
If you want to close it you can either hide it or remove it from the page. To hide it you would do some javascript like:
this.parentNode.style.display = 'none';
To remove it you use removeChild
this.parentNode.parentNode.removeChild(this.parentNode);
If you had a library like jQuery included then hiding or removing the div would be slightly easier:
$(this).parent().hide();
$(this).parent().remove();
One other thing, as your img
is in an anchor the onclick event on the anchor is going to fire as well. As the href
is set to # then the page will scroll back to the top of the page. Generally it is good practice that if you want a link to do something other than go to its href
you should set the onclick event to return false;
All modern browsers now support the unprefixed event:
element.addEventListener('transitionend', callback, false);
Works in the latest versions of Chrome, Firefox and Safari. Even IE10+.
This one uses PATINDEX to match ids from a table to a non-digit delimited integer list.
-- Given a string @myList containing character delimited integers
-- (supports any non digit delimiter)
DECLARE @myList VARCHAR(MAX) = '1,2,3,4,42'
SELECT * FROM [MyTable]
WHERE
-- When the Id is at the leftmost position
-- (nothing to its left and anything to its right after a non digit char)
PATINDEX(CAST([Id] AS VARCHAR)+'[^0-9]%', @myList)>0
OR
-- When the Id is at the rightmost position
-- (anything to its left before a non digit char and nothing to its right)
PATINDEX('%[^0-9]'+CAST([Id] AS VARCHAR), @myList)>0
OR
-- When the Id is between two delimiters
-- (anything to its left and right after two non digit chars)
PATINDEX('%[^0-9]'+CAST([Id] AS VARCHAR)+'[^0-9]%', @myList)>0
OR
-- When the Id is equal to the list
-- (if there is only one Id in the list)
CAST([Id] AS VARCHAR)=@myList
Notes:
To get a connection from a data source, the following code should work:
import java.sql.Connection;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.sql.DataSource;
Context ctx = new InitialContext();
DataSource dataSource = ctx.lookup("java:comp/env/jdbc/xxxx");
Connection conn = dataSource.getConnection();
// use the connection
conn.close();
While you can look up a data source as defined in the Websphere Data Sources config (i.e. through the websphere console) directly, the lookup from java:comp/env/jdbc/xxxx means that there needs to be an entry in web.xml:
<resource-ref>
<res-ref-name>jdbc/xxxx</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
<res-sharing-scope>Shareable</res-sharing-scope>
</resource-ref>
This means that data sources can be mapped on a per application bases and you don't need to change the name of the data source if you want to point your app to a different data source. This is useful when deploying the application to different servers (e.g. test, preprod, prod) which need to point to different databases.
Import the file into Excel by first opening excel, then going to DATA, import from TXT File, choose the csv extension which will preserve 0 prefixed values, and save that column as TEXT because excel will drop the leading 0 otherwise (DO NOT double click to open with Excel if you have numeric data in a field starting with a 0 [zero]). Then just save out as a Tab Delimited Text file. When you are importing into excel you get an option to save as GENERAL, TEXT, etc.. choose TEXT so that quotes in the middle of a string in a field like YourCompany,LLC are preserved also...

In addition to other answers, if you find the flash of template code to still be occuring it is likely you have your scripts at the bottom of the page and that means that the ng-cloak directive straight up will not work. You can either move your scripts to the head or create a CSS rule.
The docs say "For the best result, the angular.js script must be loaded in the head section of the html document; alternatively, the css rule above must be included in the external stylesheet of the application."
Now, it doesn't have to be an external stylesheet but just in a element in the head.
<style type="text/css">
.ng-cloak {
display: none !important;
}
</style>

You should always try to use a composite object with concrete types (using composite design pattern) rather than a list of object types. Who would remember what the heck each of those objects is? Think about maintenance of your code later on... Instead, try something like this:
Public (Class or Structure) MyPerson
public string FirstName { get; set; }
public string LastName { get; set; }
public string Address { get; set; }
public int ZipCode { get; set; }
End Class
And then:
Dim person as new MyPerson With { .FirstName = “Joe”,
.LastName = "Smith”,
...
}
backgroundWorker1.RunWorkerAsync(person)
and then:
private void backgroundWorker1_DoWork (object sender, DoWorkEventArgs e)
{
MyPerson person = e.Argument as MyPerson
string firstname = person.FirstName;
string lastname = person.LastName;
int zipcode = person.ZipCode;
}
If you want an synchronous request set the async
property to false
for the request. Check out the jQuery AJAX Doc
1D array of primitives does copy elements when it is cloned. This tempts us to clone 2D array(Array of Arrays).
Remember that 2D array clone doesn't work due to shallow copy implementation of clone()
.
public static void main(String[] args) {
int row1[] = {0,1,2,3};
int row2[] = row1.clone();
row2[0] = 10;
System.out.println(row1[0] == row2[0]); // prints false
int table1[][]={{0,1,2,3},{11,12,13,14}};
int table2[][] = table1.clone();
table2[0][0] = 100;
System.out.println(table1[0][0] == table2[0][0]); //prints true
}
With some Javascript you can get the exact width of the containing TD and then assign that directly to the input element.
The following is raw javascript but jQuery would make it cleaner...
var inputs = document.getElementsByTagName('input');
for (var i = 0; i < inputs.length; i++)
{
var el = inputs[i];
if (el.style.width == '100%')
{
var pEl = el.parentNode; // Assumes the parent node is the TD...
el.style.width = pEl.offsetWidth;
}
}
The issues with this solution are:
1) If you have your inputs contained in another element such as a SPAN then you will need loop up and find the TD because elements like SPANs will wrap the input and show its size rather then being limited to the size of the TD.
2) If you have padding or margins added at different levels then you might have to explicitly subtract that from [pEl.offsetWidth]. Depending on your HTML structure that can be calculated.
3) If the table columns are sized dynamically then changing the size of one element will cause the table to reflow in some browsers and you might get a stepped effect as you sequentially "fix" the input sizes. The solution is to assign specific widths to the column either as percentages or pixels OR collect the new widths and set them after. See the code below..
var inputs = document.getElementsByTagName('input');
var newSizes = [];
for (var i = 0; i < inputs.length; i++)
{
var el = inputs[i];
if (el.style.width == '100%')
{
var pEl = el.parentNode; // Assumes the parent node is the TD...
newSizes.push( { el: el, width: pEl.offsetWidth });
}
}
// Set the sizes AFTER to avoid stepping...
for (var i = 0; i < newSizes.length; i++)
{
newSizes[i].el.style.width = newSizes[i].width;
}
You can get list of temp tables by following query :
select left(name, charindex('_',name)-1)
from tempdb..sysobjects
where charindex('_',name) > 0 and
xtype = 'u' and not object_id('tempdb..'+name) is null
Many UNIX programs respect the http_proxy
environment variable, curl included. The format curl accepts is [protocol://]<host>[:port]
.
In your shell configuration:
export http_proxy http://proxy.server.com:3128
For proxying HTTPS requests, set https_proxy
as well.
Curl also allows you to set this in your .curlrc
file (_curlrc
on Windows), which you might consider more permanent:
http_proxy=http://proxy.server.com:3128
I'm going to hazard a historical and practical hot take here:
Yes, according to specifications, <strong>
had a semantic meaning in HTML4 and <b>
had a strictly presentational meaning.
Yes, when HTML5 came along, new semantic meaning that was slightly different was introduced for b
and i
.
Yes, the W3C recommends — basically — TL,DR; don't use b and i.
You should always bear in mind that the content of a b element may not always be bold, and that of an i element may not always be italic. The actual style is dependent on the CSS style definitions. You should also bear in mind that bold and italic may not be the preferred style for content in certain languages. You should not use b and i tags if there is a more descriptive and relevant tag available.
BUT:
The real world internet has massive loads of existing HTML that is never going to get updated. The real world internet has to account for content generated and copy and pasted between a vast network of software and CMS systems that all have different developer teams and were built in different eras.
So if you're writing HTML or building a system that writes HTML for other people — sure — definitely use <strong>
instead of <b>
to mean "strongly emphasized" because it's more semantically correct.
But really, the on-the-ground reality is that the semantic and stylistic meaning of <strong>
and <b>
have merged over time out of necessity.
If I'm building a CMS that allows any pasting of styled text, I need to plan both for people who are pasting in <b>
and mean "strongly emphasized" and for people who are pasting in <strong>
and mean "make this text bold". It might not be "right", but it's how the real world works at this moment in time.
And so, if I'm writing a stylesheet for that site, I'm probably going to end up writing some styles that look like this:
b,
strong {
font-weight: 700;
/* ... more styles here */
}
i,
em {
font-style: italic;
/* ... more styles here */
}
Or, I'm going to rely on the browser defaults, which do the same thing as the code above in every modern browser I know of.
Or, I might be one of probably millions of sites that use normalize.css, which takes care to ensure that b and strong are treated the same.
There's such a massive ocean of HTML out there in the world already that works off of this expectation, I just can't imagine that b
will EVER be depreciated in favor of strong
or that browsers will ever start displaying them differently by default.
So that's it. That's my hot take on semantics, history and the real world. Are b/i and strong/em the same? No. Will they probably both exist and be treated as identical in almost every situation until the collapse of modern civilization? I think, yes.
Presumably, those columns are integer columns - which will be the reason as the result of the calculation will be of the same type.
e.g. if you do this:
SELECT 1 / 2
you will get 0, which is obviously not the real answer. So, convert the values to e.g. decimal and do the calculation based on that datatype instead.
e.g.
SELECT CAST(1 AS DECIMAL) / 2
gives 0.500000
Try converting your procedure in to an Inline Function which returns a table as follows:
CREATE FUNCTION MyProc()
RETURNS TABLE AS
RETURN (SELECT * FROM MyTable)
And then you can call it as
SELECT * FROM MyProc()
You also have the option of passing parameters to the function as follows:
CREATE FUNCTION FuncName (@para1 para1_type, @para2 para2_type , ... )
And call it
SELECT * FROM FuncName ( @para1 , @para2 )
Call this method:
public static void shareApp(Context context)
{
final String appPackageName = context.getPackageName();
Intent sendIntent = new Intent();
sendIntent.setAction(Intent.ACTION_SEND);
sendIntent.putExtra(Intent.EXTRA_TEXT, "Check out the App at: https://play.google.com/store/apps/details?id=" + appPackageName);
sendIntent.setType("text/plain");
context.startActivity(sendIntent);
}
emplace_back
shouldn't take an argument of type vector::value_type
, but instead variadic arguments that are forwarded to the constructor of the appended item.
template <class... Args> void emplace_back(Args&&... args);
It is possible to pass a value_type
which will be forwarded to the copy constructor.
Because it forwards the arguments, this means that if you don't have rvalue, this still means that the container will store a "copied" copy, not a moved copy.
std::vector<std::string> vec;
vec.emplace_back(std::string("Hello")); // moves
std::string s;
vec.emplace_back(s); //copies
But the above should be identical to what push_back
does. It is probably rather meant for use cases like:
std::vector<std::pair<std::string, std::string> > vec;
vec.emplace_back(std::string("Hello"), std::string("world"));
// should end up invoking this constructor:
//template<class U, class V> pair(U&& x, V&& y);
//without making any copies of the strings
Paste my contains
example here:
//table[contains(@class, "EC_result")]/tbody
Another solution, if you find yourself casting the same object a lot and you don't want to litter your code with @SupressWarnings("unchecked")
, would be to create a method with the annotation. This way you're centralizing the cast, and hopefully reducing the possibility for error.
@SuppressWarnings("unchecked")
public static List<String> getFooStrings(Map<String, List<String>> ctx) {
return (List<String>) ctx.get("foos");
}
It looks like you are trying to set elements 0 through 11 of PriceList to new values. The syntax would usually look like this:
prompt = "What would you like the new price for all standard pizzas to be? "
PizzaChange = float(input(prompt))
for i in [0, 1, 2, 3, 4, 5, 6]: PriceList[i] = PizzaChange
for i in [7, 8, 9, 10, 11]: PriceList[i] = PizzaChange + 3
If they are always consecutive ranges, then it's even simpler to write:
prompt = "What would you like the new price for all standard pizzas to be? "
PizzaChange = float(input(prompt))
for i in range(0, 7): PriceList[i] = PizzaChange
for i in range(7, 12): PriceList[i] = PizzaChange + 3
For reference, PriceList[0][1][2][3][4][5][6]
refers to "Element 6 of element 5 of element 4 of element 3 of element 2 of element 1 of element 0 of PriceList
. Put another way, it's the same as ((((((PriceList[0])[1])[2])[3])[4])[5])[6]
.
You cannot change the order of columns in smaller screens but you can do that in large screens.
So change the order of your columns.
<!--Main Content-->
<div class="col-lg-9 col-lg-push-3">
</div>
<!--Sidebar-->
<div class="col-lg-3 col-lg-pull-9">
</div>
By default this displays the main content first.
So in mobile main content is displayed first.
By using col-lg-push
and col-lg-pull
we can reorder the columns in large screens and display sidebar on the left and main content on the right.

Actually, I think you might be confused by how you should run a script
.
If you use sh
to run a script, say, sh ./run2.sh
, even if the embedded script ends with exit
, your terminal window will still remain.
However if you use .
or source
, your terminal window will exit/close as well when subscript ends.
for more detail, please refer to What is the difference between using sh
and source
?
This worked for me:
$(document).on('keydown', ':tabbable', function(e) {
if (e.key === "Enter") {
e.preventDefault();
var $canfocus = $(':tabbable:visible');
var index = $canfocus.index(document.activeElement) + 1;
if (index >= $canfocus.length) index = 0;
$canfocus.eq(index).focus();
}
});
"ABCDEFG".chars.each do |char|
puts char
end

"ABCDEFG".each_char {|char| p char}

If the attribute you want to sort by is a property, then you can avoid importing operator.attrgetter
and use the property's fget
method instead.
For example, for a class Circle
with a property radius
we could sort a list of circles
by radii as follows:
result = sorted(circles, key=Circle.radius.fget)
This is not the most well-known feature but often saves me a line with the import.
I might be misunderstanding me, but isn't this exactly what a pivot table does? Do you have the data in a table or just a filtered list? If its not a table make it one (ctrl+l) if it is, then simply activate any cell in the table and insert a pivot table on another sheet. Then Add the columns lastname, firstname, phonenumber to the rows section. Then Add Phone number to the filter section and filter out the null values. Now Sort like normal.
If you happen to know your ASCII table off by heart and not MaxInt
:
!GH6G = 21 47 48 36 47
Just change your controller to the following:
public function create()
{
$items = Subject::all(['id', 'name']);
return View::make('your view', compact('items',$items));
}
And your view to:
<div class="form-group">
{!! Form::Label('item', 'Item:') !!}
<select class="form-control" name="item_id">
@foreach($items as $item)
<option value="{{$item->item_id}}">{{$item->id}}</option>
@endforeach
</select>
</div>
Hope this will solve your problem
For Expose.class Error i.e

In Maven: The Definitive Guide, I wrote about the differences between Maven and Ant in the introduction the section title is "The Differences Between Ant and Maven". Here's an answer that is a combination of the info in that introduction with some additional notes.
A Simple Comparison
I'm only showing you this to illustrate the idea that, at the most basic level, Maven has built-in conventions. Here's a simple Ant build file:
<project name="my-project" default="dist" basedir=".">
<description>
simple example build file
</description>
<!-- set global properties for this build -->
<property name="src" location="src/main/java"/>
<property name="build" location="target/classes"/>
<property name="dist" location="target"/>
<target name="init">
<!-- Create the time stamp -->
<tstamp/>
<!-- Create the build directory structure used by compile -->
<mkdir dir="${build}"/>
</target>
<target name="compile" depends="init"
description="compile the source " >
<!-- Compile the java code from ${src} into ${build} -->
<javac srcdir="${src}" destdir="${build}"/>
</target>
<target name="dist" depends="compile"
description="generate the distribution" >
<!-- Create the distribution directory -->
<mkdir dir="${dist}/lib"/>
<!-- Put everything in ${build} into the MyProject-${DSTAMP}.jar file
-->
<jar jarfile="${dist}/lib/MyProject-${DSTAMP}.jar" basedir="${build}"/>
</target>
<target name="clean"
description="clean up" >
<!-- Delete the ${build} and ${dist} directory trees -->
<delete dir="${build}"/>
<delete dir="${dist}"/>
</target>
</project>
In this simple Ant example, you can see how you have to tell Ant exactly what to do. There is a compile goal which includes the javac task that compiles the source in the src/main/java directory to the target/classes directory. You have to tell Ant exactly where your source is, where you want the resulting bytecode to be stored, and how to package this all into a JAR file. While there are some recent developments that help make Ant less procedural, a developer's experience with Ant is in coding a procedural language written in XML.
Contrast the previous Ant example with a Maven example. In Maven, to create a JAR file from some Java source, all you need to do is create a simple pom.xml, place your source code in ${basedir}/src/main/java and then run mvn install from the command line. The example Maven pom.xml that achieves the same results.
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>org.sonatype.mavenbook</groupId>
<artifactId>my-project</artifactId>
<version>1.0</version>
</project>
That's all you need in your pom.xml. Running mvn install from the command line will process resources, compile source, execute unit tests, create a JAR, and install the JAR in a local repository for reuse in other projects. Without modification, you can run mvn site and then find an index.html file in target/site that contains links to JavaDoc and a few reports about your source code.
Admittedly, this is the simplest possible example project. A project which only contains source code and which produces a JAR. A project which follows Maven conventions and doesn't require any dependencies or customization. If we wanted to start customizing the behavior, our pom.xml is going to grow in size, and in the largest of projects you can see collections of very complex Maven POMs which contain a great deal of plugin customization and dependency declarations. But, even when your project's POM files become more substantial, they hold an entirely different kind of information from the build file of a similarly sized project using Ant. Maven POMs contain declarations: "This is a JAR project", and "The source code is in src/main/java". Ant build files contain explicit instructions: "This is project", "The source is in src/main/java
", "Run javac
against this directory", "Put the results in target/classses
", "Create a JAR from the ....", etc. Where Ant had to be explicit about the process, there was something "built-in" to Maven that just knew where the source code was and how it should be processed.
High-level Comparison
The differences between Ant and Maven in this example? Ant...
Where Maven...
mvn install
. This command told Maven to execute a series of sequence steps until it reached the lifecycle. As a side-effect of this journey through the lifecycle, Maven executed a number of default plugin goals which did things like compile and create a JAR.What About Ivy?
Right, so someone like Steve Loughran is going to read that comparison and call foul. He's going to talk about how the answer completely ignores something called Ivy and the fact that Ant can reuse build logic in the more recent releases of Ant. This is true. If you have a bunch of smart people using Ant + antlibs + Ivy, you'll end up with a well designed build that works. Even though, I'm very much convinced that Maven makes sense, I'd happily use Ant + Ivy with a project team that had a very sharp build engineer. That being said, I do think you'll end up missing out on a number of valuable plugins such as the Jetty plugin and that you'll end up doing a whole bunch of work that you didn't need to do over time.
More Important than Maven vs. Ant
Suppose currently in your branch myBranch
Do the following :-
git status
If all changes are committed
git pull origin master
If changes are not committed than
git add .
git commit -m"commit changes"
git pull origin master
Check if there are any conflicts than resolve and commit changes
git add .
git commit -m"resolved conflicts message"
And than push
git push origin myBranch
Estimates are a useful tool for me, as development line manager, to plan what my team is working on.
They are not a promise of a feature's delivery on a specific date, and they are not a stick for driving the team to work harder.
IMHO if you force developers to commit to estimates you get the safest possible figure.
For instance -
I think a feature will probably take me around 5 days. There's a small chance of an issue that would make it take 30 days.
If the estimates are just for planning then we'll all work to 5 days, and account for the small chance of an issue should it arise.
However - if meeting that estimate is required as a promise of delivery what estimate do you think gets given?
If a developer's bonus or job security depends on meeting an estimate do you think they give their most accurate guess or the one they're most certain they will meet?
This opinion of mine is controversial with other management, and has been interpreted as me trying to worm my way out of having proper targets, or me trying to cover up poor performance. It's a tough sell every time, but one that I've gotten used to making.
SDK represents to software development kit, and IDE represents to integrated development environment. The IDE is the software or the program is used to write, compile, run, and debug such as Xcode. The SDK is the underlying engine of the IDE, includes all the platform's libraries an app needs to access. It's more basic than an IDE because it doesn't usually have graphical tools.
This really is beyond the capabilities of shell script. Shell script and the standard Unix tools are okay at parsing line oriented files, but things change when you talk about XML. Even simple tags can present a problem:
<MYTAG>Data</MYTAG>
<MYTAG>
Data
</MYTAG>
<MYTAG param="value">Data</MYTAG>
<MYTAG><ANOTHER_TAG>Data
</ANOTHER_TAG><MYTAG>
Imagine trying to write a shell script that can read the data enclosed in . The three very, very simply XML examples all show different ways this can be an issue. The first two examples are the exact same syntax in XML. The third simply has an attribute attached to it. The fourth contains the data in another tag. Simple sed
, awk
, and grep
commands cannot catch all possibilities.
You need to use a full blown scripting language like Perl, Python, or Ruby. Each of these have modules that can parse XML data and make the underlying structure easier to access. I've use XML::Simple in Perl. It took me a few tries to understand it, but it did what I needed, and made my programming much easier.
For more modularity and in case you have many background images that you want to incorporate wherever you want you can for each image create a class :
.background-image1
{
background: url(image1.jpg);
}
.background-image2
{
background: url(image2.jpg);
}
and then insert the image wherever you want by adding a div
<div class='background-image1'>
<div class="page-header text-center", style='margin: 20px 0 0px;'>
<h1>blabaaboabaon</h1>
</div>
</div>
Chrome 58 has dropped support for certificates without Subject Alternative Names.
Moving forward, this might be another reason for you encountering this error.
Please find below the easy way :
XSSFCellStyle style = workbook.createCellStyle();
style.setBorderTop((short) 6); // double lines border
style.setBorderBottom((short) 1); // single line border
XSSFFont font = workbook.createFont();
font.setFontHeightInPoints((short) 15);
font.setBoldweight(XSSFFont.BOLDWEIGHT_BOLD);
style.setFont(font);
Row row = sheet.createRow(0);
Cell cell0 = row.createCell(0);
cell0.setCellValue("Nav Value");
cell0.setCellStyle(style);
for(int j = 0; j<=3; j++)
row.getCell(j).setCellStyle(style);
You can using Javascript.
var CurrDate = new Date(); // Current Date
var numberOfDays = 5;
var days = CurrDate.setDate(CurrDate.getDate() + numberOfDays);
alert(days); // It will print 5 days before today
For PHP,
$date = date('Y-m-d', strtotime("-5 days")); // it shows 5 days before today.
echo $date;
Hope it will help you.
I really like Dan Beaulieu's answer, but it doesn't work with Swift 2.2 and I think we can avoid those nasty forced unwraps!
func backgroundThread(delay: Double = 0.0, background: (() -> Void)? = nil, completion: (() -> Void)? = nil) {
dispatch_async(dispatch_get_global_queue(QOS_CLASS_USER_INITIATED, 0)) {
background?()
if let completion = completion{
let popTime = dispatch_time(DISPATCH_TIME_NOW, Int64(delay * Double(NSEC_PER_SEC)))
dispatch_after(popTime, dispatch_get_main_queue()) {
completion()
}
}
}

As already answered, this is per spec not possible with the fetch
-API, yet. But I have to note:
If you are on node
, there's the querystring
package. It can stringify/parse objects/querystrings:
var querystring = require('querystring')
var data = { key: 'value' }
querystring.stringify(data) // => 'key=value'
...then just append it to the url to request.
However, the problem with the above is, that you always have to prepend a question mark (?
). So, another way is to use the parse
method from nodes url
package and do it as follows:
var url = require('url')
var data = { key: 'value' }
url.format({ query: data }) // => '?key=value'
See query
at https://nodejs.org/api/url.html#url_url_format_urlobj
This is possible, as it does internally just this:
search = obj.search || (
obj.query && ('?' + (
typeof(obj.query) === 'object' ?
querystring.stringify(obj.query) :
String(obj.query)
))
) || ''
You can just locate pg_dump
and use the full path in command
locate pg_dump
/usr/bin/pg_dump
/usr/bin/pg_dumpall
/usr/lib/postgresql/9.3/bin/pg_dump
/usr/lib/postgresql/9.3/bin/pg_dumpall
/usr/lib/postgresql/9.6/bin/pg_dump
/usr/lib/postgresql/9.6/bin/pg_dumpall
Now just use the path of the desired version in the command
/usr/lib/postgresql/9.6/bin/pg_dump books > books.out
Just a notice for a sharing hosting server or added on domains =
For your settings to work you must have a different save session dir for added domain by using php_value session.save_path folderA/sessionsA
.
So create a folder to your root server, not into the public_html
and not to be publicity accessed from outside. For my cpanel/server worked fine the folder permissions 0700
. Give a try...
# Session timeout, 2628000 sec = 1 month, 604800 = 1 week, 57600 = 16 hours, 86400 = 1 day
ini_set('session.save_path', '/home/server/.folderA_sessionsA');
ini_set('session.gc_maxlifetime', 57600);
ini_set('session.cookie_lifetime', 57600);
# session.cache_expire is in minutes unlike the other settings above
ini_set('session.cache_expire', 960);
ini_set('session.name', 'MyDomainA');
before session_start();
or put this in your .htaccess
file.
php_value session.save_path /home/server/.folderA_sessionsA
php_value session.gc_maxlifetime 57600
php_value session.cookie_lifetime 57600
php_value session.cache_expire 57600
php_value session.name MyDomainA
After many researching and testing this worked fine for shared cpanel/php7 server. Many thanks to: NoiS
I don't know if it would work, but what about calling sync
?
I used tableViewCell to show multiple data, after swipe () right to left on a cell it will show two buttons Approve And reject, there are two methods, the first one is ApproveFunc which takes one argument, and the another one is RejectFunc which also takes one argument.
func tableView(_ tableView: UITableView, editActionsForRowAt indexPath: IndexPath) -> [UITableViewRowAction]? {
let Approve = UITableViewRowAction(style: .normal, title: "Approve") { action, index in
self.ApproveFunc(indexPath: indexPath)
}
Approve.backgroundColor = .green
let Reject = UITableViewRowAction(style: .normal, title: "Reject") { action, index in
self.rejectFunc(indexPath: indexPath)
}
Reject.backgroundColor = .red
return [Reject, Approve]
}
func tableView(_ tableView: UITableView, canEditRowAt indexPath: IndexPath) -> Bool {
return true
}
func ApproveFunc(indexPath: IndexPath) {
print(indexPath.row)
}
func rejectFunc(indexPath: IndexPath) {
print(indexPath.row)

sort dictionary 'in_dict' by value in decreasing order
sorted_dict = {r: in_dict[r] for r in sorted(in_dict, key=in_dict.get, reverse=True)}

sorted_d = {r: d[r] for r in sorted(d, key=d.get('key3'), reverse=True)}
The accepted solution used to work for me once, but not now. I had to re-create a hello-world of the same kind (!) in a new workspace, made it compile, and then copied all directories, including .hg
and .hgignore
.
hg diff
shows:
- android:targetSdkVersion="19" />
+ android:targetSdkVersion="21" />
Binary file libs/android-support-v4.jar has changed
It looks like Eclipse wants to compile for API 21 and fails to do anything with API 19. Darkly.
It is easier to check if a rectangle is completly outside the other, so if it is either
on the left...
(r1.x + r1.width < r2.x)
or on the right...
(r1.x > r2.x + r2.width)
or on top...
(r1.y + r1.height < r2.y)
or on the bottom...
(r1.y > r2.y + r2.height)
of the second rectangle, it cannot possibly collide with it. So to have a function that returns a Boolean saying weather the rectangles collide, we simply combine the conditions by logical ORs and negate the result:
function checkOverlap(r1, r2) : Boolean
{
return !(r1.x + r1.width < r2.x || r1.y + r1.height < r2.y || r1.x > r2.x + r2.width || r1.y > r2.y + r2.height);
}
To already receive a positive result when touching only, we can change the "<" and ">" by "<=" and ">=".
DTO
is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.
DTO
should only contain private fields for your data, getters, setters, and constructors.DTO
is not recommended to add business logic methods to such classes, but it is OK to add some util methods.DAO
is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).
Here is an example of how the DAO and DTO interfaces would look like:
interface PersonDTO {
String getName();
void setName(String name);
//.....
}
interface PersonDAO {
PersonDTO findById(long id);
void save(PersonDTO person);
//.....
}
The MVC
is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.
As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.
a potentially more efficient algorithm than the ones presented here already (especially if there are small prime factons in n
). the trick here is to adjust the limit up to which trial division is needed every time prime factors are found:
def factors(n):
'''
return prime factors and multiplicity of n
n = p0^e0 * p1^e1 * ... * pk^ek encoded as
res = [(p0, e0), (p1, e1), ..., (pk, ek)]
'''
res = []
# get rid of all the factors of 2 using bit shifts
mult = 0
while not n & 1:
mult += 1
n >>= 1
if mult != 0:
res.append((2, mult))
limit = round(sqrt(n))
test_prime = 3
while test_prime <= limit:
mult = 0
while n % test_prime == 0:
mult += 1
n //= test_prime
if mult != 0:
res.append((test_prime, mult))
if n == 1: # only useful if ek >= 3 (ek: multiplicity
break # of the last prime)
limit = round(sqrt(n)) # adjust the limit
test_prime += 2 # will often not be prime...
if n != 1:
res.append((n, 1))
return res
this is of course still trial division and nothing more fancy. and therefore still very limited in its efficiency (especially for big numbers without small divisors).
this is python3; the division //
should be the only thing you need to adapt for python 2 (add from __future__ import division
).
This can be archived by adding code on the onchange event of the select control.
For Example:
<select onchange="this.options[this.selectedIndex].value && (window.location = this.options[this.selectedIndex].value);">
<option value="http://gmail.com">Gmail</option>
<option value="http://youtube.com">Youtube</option>
</select>
A request to list "Number of employees in each department" or "Display how many people work in each department" is the same as "For each department, list the number of employees", this must include departments with no employees. In the sample database, Operations has 0 employees. So a LEFT OUTER JOIN should be used.
SELECT dept.name, COUNT(emp.empno) AS count
FROM dept
LEFT OUTER JOIN emp ON emp.deptno = dept.deptno
GROUP BY dept.name;
When you call test
with &nKByte
, the address-of operator creates a temporary value, and you can't normally have references to temporary values because they are, well, temporary.
Either do not use a reference for the argument, or better yet don't use a pointer.
Use this:
os.path.splitext("name.fasta")[0]+".aln"
And here is how the above works:
The splitext method separates the name from the extension creating a tuple:
os.path.splitext("name.fasta")
the created tuple now contains the strings "name" and "fasta". Then you need to access only the string "name" which is the first element of the tuple:
os.path.splitext("name.fasta")[0]
And then you want to add a new extension to that name:
os.path.splitext("name.fasta")[0]+".aln"
It looks like you can use msdb.dbo.sysjobactivity
, checking for a record with a non-null start_execution_date and a null stop_execution_date, meaning the job was started, but has not yet completed.
This would give you currently running jobs:
SELECT sj.name
, sja.*
FROM msdb.dbo.sysjobactivity AS sja
INNER JOIN msdb.dbo.sysjobs AS sj ON sja.job_id = sj.job_id
WHERE sja.start_execution_date IS NOT NULL
AND sja.stop_execution_date IS NULL
Just found the answer, in this SO question (literally, inside the question, not any answer):
SELECT @@servername
returns servername\instance as far as this is not the default instance
SELECT @@servicename
returns instance name, even if this is the default (MSSQLSERVER)
You can use Array.prototype.find function in javascript. Array find MDN.
So to find string in array of string, the code becomes very simple. Plus as browser implementation, it will provide good performance.
Ex.
var strs = ['abc', 'def', 'ghi', 'jkl', 'mno'];
var value = 'abc';
strs.find(
function(str) {
return str == value;
}
);
or using lambda expression it will become much shorter
var strs = ['abc', 'def', 'ghi', 'jkl', 'mno'];
var value = 'abc';
strs.find((str) => str === value);
Shuffling is the process by which intermediate data from mappers are transferred to 0,1 or more reducers. Each reducer receives 1 or more keys and its associated values depending on the number of reducers (for a balanced load). Further the values associated with each key are locally sorted.
Because, on whatever line the error is occurring at (you didn't tell us which that is), you're passing something to foreach
that is not an array.
Look at what you're passing into foreach
, determine what it is (with var_export
), find out why it's not an array... and fix it.
Basic, basic debugging.
Try this
#include <stdio.h>
struct context;
struct funcptrs{
void (*func0)(struct context *ctx);
void (*func1)(void);
};
struct context{
struct funcptrs fps;
};
void func1 (void) { printf( "1\n" ); }
void func0 (struct context *ctx) { printf( "0\n" ); }
void getContext(struct context *con){
con->fps.func0 = func0;
con->fps.func1 = func1;
}
int main(int argc, char *argv[]){
struct context c;
c.fps.func0 = func0;
c.fps.func1 = func1;
getContext(&c);
c.fps.func0(&c);
getchar();
return 0;
}
It has to do with how the list comprehension is performed.
Keep in mind the following:
[ expression for item in list if conditional ]
Is equivalent to:
for item in list:
if conditional:
expression
Where the expression
is in a slightly different format (think switching the subject and verb order in a sentence).
Therefore, your code [x+1 for x in l if x >= 45]
does this:
for x in l:
if x >= 45:
x+1
However, this code [x+1 if x >= 45 else x+5 for x in l]
does this (after rearranging the expression
):
for x in l:
if x>=45: x+1
else: x+5
The second function should have:
var value = document.getElementById(id).value;
Then they are basically the same function.
What is DATA ACCESS OBJECT (DAO) -
It is a object/interface, which is used to access data from database of data storage.
WHY WE USE DAO:
it abstracts the retrieval of data from a data resource such as a database. The concept is to "separate a data resource's client interface from its data access mechanism."
The problem with accessing data directly is that the source of the data can change. Consider, for example, that your application is deployed in an environment that accesses an Oracle database. Then it is subsequently deployed to an environment that uses Microsoft SQL Server. If your application uses stored procedures and database-specific code (such as generating a number sequence), how do you handle that in your application? You have two options:
Its in all referred as DAO Pattern, It consist of following:
Please check this example, This will clear things more clearly.
Example
I assume this things must have cleared your understanding of DAO up to certain extend.
A character set is a subset of all written glyphs. A character encoding specifies how those characters are mapped to numeric values. Some character encodings, like UTF-8 and UTF-16, can encode any character in the Universal Character Set. Others, like US-ASCII or ISO-8859-1 can only encode a small subset, since they use 7 and 8 bits per character, respectively. Because many standards specify both a character set and a character encoding, the term "character set" is often substituted freely for "character encoding".
A collation comprises rules that specify how characters can be compared for sorting. Collations rules can be locale-specific: the proper order of two characters varies from language to language.
Choosing a character set and collation comes down to whether your application is internationalized or not. If not, what locale are you targeting?
In order to choose what character set you want to support, you have to consider your application. If you are storing user-supplied input, it might be hard to foresee all the locales in which your software will eventually be used. To support them all, it might be best to support the UCS (Unicode) from the start. However, there is a cost to this; many western European characters will now require two bytes of storage per character instead of one.
Choosing the right collation can help performance if your database uses the collation to create an index, and later uses that index to provide sorted results. However, since collation rules are often locale-specific, that index will be worthless if you need to sort results according to the rules of another locale.
Here's mine:
git remote --verbose | grep origin | grep fetch | cut -f2 | cut -d' ' -f1
no better than the others, but I made it a bash function so I can drop in the remote name if it isn't origin.
grurl () {
xx_remote=$1
[ -z "$xx_remote" ] && xx_remote=origin
git remote --verbose | grep "$1" | grep fetch | cut -f2 | cut -d' ' -f1
unset xx_remote
}
Found my solution on Apache/2.2.15 (Unix).

I switched from @Inject
to @EJB
because @EJB
allows circular injection whereas @Inject
pukes on it.
Details: I needed @PostConstruct
to call an @Asynchronous
method but it would do so synchronously. The only way to make the asynchronous call was to have the original call a method of another bean and have it call back the method of the original bean. To do this each bean needed a reference to the other -- thus circular. @Inject
failed for this task whereas @EJB
worked.

Solved, just use select method for the dataframe to select columns:
val df=spark.read.csv("C:\\Users\\Ahmed\\Desktop\\cabs_trajectories\\cabs_trajectories\\green\\2014\\green_tripdata_2014-09.csv")
val df1=df.select("_c0")
this would subset the first column of the dataframe

It seems to change from one keyboard layout to another, so better look for it with Cmd+Shift+P and type "go to bracket" as others suggested.
There are MYSQL functions you can use. Like this one that resolves the user:
SELECT USER();
This will return something like root@localhost
so you get the host and the user.
To get the current database run this statement:
SELECT DATABASE();

This is my solution for the problem. This is controller with 2 action methods
public class FeedbackController : Controller
{
public ActionResult Index()
{
var feedbacks =dataFromSomeSource.getData;
return View(feedbacks);
}
[System.Web.Mvc.HttpDelete]
[System.Web.Mvc.Authorize(Roles = "admin")]
public ActionResult Delete([FromBody]int id)
{
return RedirectToAction("Index");
}
}
In View I render construct following structure.
<html>
..
<script src="~/Scripts/bootbox.min.js"></script>
<script>
function confirmDelete(id) {
bootbox.confirm('@Resources.Resource.AreYouSure', function(result) {
if (result) {
document.getElementById('idField').value = id;
document.getElementById('myForm').submit();
}
}.bind(this));
}
</script>
@using (Html.BeginForm("Delete", "Feedback", FormMethod.Post, new { id = "myForm" }))
{
@Html.HttpMethodOverride(HttpVerbs.Delete)
@Html.Hidden("id",null,new{id="idField"})
foreach (var feedback in @Model)
{
if (User.Identity.IsAuthenticated && User.IsInRole("admin"))
{
@Html.ActionLink("Delete Item", "", new { id = @feedback.Id }, new { onClick = "confirmDelete("+feedback.Id+");return false;" })
}
}
...
</html>
Point of interest in Razor View:
JavaScript function confirmDelete(id)
which is called when the link generated with @Html.ActionLink
is clicked;
confirmDelete()
function required id of item being clicked. This item is passed from onClick
handler confirmDelete("+feedback.Id+");return false;
Pay attention handler returns false to prevent default action - which is get request to target. OnClick
event for buttons could be attached with jQuery for all buttons in the list as alternative (probably it will be even better, as it will be less text in the HTML page and data could be passed via data-
attribute).
Form has id=myForm
, in order to find it in confirmDelete()
.
Form includes @Html.HttpMethodOverride(HttpVerbs.Delete)
in order to use the HttpDelete
verb, as action marked with the HttpDeleteAttribute
.
In the JS function I do use action confirmation (with help of external plugin, but standard confirm works fine too. Don't forget to use bind()
in call back or var that=this
(whatever you prefer).
Form has a hidden element with id='idField'
and name='id'
. So before the form is submitted after confirmation (result==true
), the value of the hidden element is set to value passed argument and browser will submit data to controller like this:
Request URL:http://localhost:38874/Feedback/Delete
Request Method:POST Status Code:302 Found
Response Headers
Location:/Feedback Host:localhost:38874 Form Data X-HTTP-Method-Override:DELETE id:5
As you see it is POST request with X-HTTP-Method-Override:DELETE and data in body set to "id:5". Response has 302 code which redirect to Index action, by this you refresh your screen after delete.
The simples way arround is to put -40dp margin at the buttom of the top imageview
Bonus answer since this use-case brought me here:
In the case where you need to do this as some other user
echo "some output" | sudo -u some_user tee /some/path/some_file
Note that the echo will happen as you and the file write will happen as "some_user" what will NOT work is if you were to run the echo as "some_user" and redirect the output with >> "some_file" because the file redirect will happen as you.
Hint: tee also supports append with the -a flag, if you need to replace a line in a file as another user you could execute sed as the desired user.
cvc-elt.1: Cannot find the declaration of element 'Root'. [7]
Your schemaLocation
attribute on the root element should be xsi:schemaLocation
, and you need to fix it to use the right namespace.
You should probably change the targetNamespace
of the schema and the xmlns
of the document to http://myNameSpace.com
(since namespaces are supposed to be valid URIs, which Test.Namespace
isn't, though urn:Test.Namespace
would be ok). Once you do that it should find the schema. The point is that all three of the schema's target namespace, the document's namespace, and the namespace for which you're giving the schema location must be the same.
(though it still won't validate as your <element2>
contains an <element3>
in the document where the schema expects item
)
In Bash and zsh you can do this with Brace Expansion. This simply expands a list of items in braces. For example:
# echo {vanilla,chocolate,strawberry}-ice-cream
vanilla-ice-cream chocolate-ice-cream strawberry-ice-cream
So you can do your rename as follows:
mv {,new.}original.filename
as this expands to:
mv original.filename new.original.filename

Try using cmake itself. In the build directory, run:
cmake --build .
In C++ the stack memory is where local variables get stored/constructed. The stack is also used to hold parameters passed to functions.
The stack is very much like the std::stack class: you push parameters onto it and then call a function. The function then knows that the parameters it expects can be found on the end of the stack. Likewise, the function can push locals onto the stack and pop them off it before returning from the function. (caveat - compiler optimizations and calling conventions all mean things aren't this simple)
The stack is really best understood from a low level and I'd recommend Art of Assembly - Passing Parameters on the Stack. Rarely, if ever, would you consider any sort of manual stack manipulation from C++.
Generally speaking, the stack is preferred as it is usually in the CPU cache, so operations involving objects stored on it tend to be faster. However the stack is a limited resource, and shouldn't be used for anything large. Running out of stack memory is called a Stack buffer overflow. It's a serious thing to encounter, but you really shouldn't come across one unless you have a crazy recursive function or something similar.
Heap memory is much as rskar says. In general, C++ objects allocated with new, or blocks of memory allocated with the likes of malloc end up on the heap. Heap memory almost always must be manually freed, though you should really use a smart pointer class or similar to avoid needing to remember to do so. Running out of heap memory can (will?) result in a std::bad_alloc.
std::is_same()
is only available since C++11. For pre-C++11 you can use typeid()
:
template <typename T>
void foo()
{
if (typeid(T) == typeid(animal)) { /* ... */ }
}
You could also do
var x = $('#element').height(); // or any changing value
$('selector').css({'top' : x + 'px'});
OR
You can use directly
$('#element').css( "height" )
The difference between .css( "height" )
and .height()
is that the latter returns a unit-less pixel value (for example, 400
) while the former returns a value with units intact (for example, 400px
). The .height() method is recommended when an element's height needs to be used in a mathematical calculation. jquery doc
you can try like this:
d?.property1 , d?.property2
I have tested it and working with .netcore 2.1
public class SQLCon
{
public static string cs =
ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString;
}

SqlDataAdapter MyDataAdapter;
SQLCon cs = new SQLCon();
DataSet RsUser = new DataSet();
RsUser = new DataSet();
using (SqlConnection MyConnection = new SqlConnection(SQLCon.cs))
{
MyConnection.Open();
MyDataAdapter = new SqlDataAdapter("GetAPPID", MyConnection);
//'Set the command type as StoredProcedure.
MyDataAdapter.SelectCommand.CommandType = CommandType.StoredProcedure;
RsUser = new DataSet();
MyDataAdapter.SelectCommand.Parameters.Add(new SqlParameter("@organizationID",
SqlDbType.Int));
MyDataAdapter.SelectCommand.Parameters["@organizationID"].Value = TxtID.Text;
MyDataAdapter.Fill(RsUser, "GetAPPID");
}
if (RsUser.Tables[0].Rows.Count > 0) //data was found
{
Session["AppID"] = RsUser.Tables[0].Rows[0]["AppID"].ToString();
}
else
{
}
}
If anyone is working a project which is synced via Subversion and this still happening, I think this can slow the process of workflow in Android Studio. For example if it work very slow while: scrolling in a class,xml etc, while my app is still running on my device.
here is direct link for api 17 documentation. Just extract at under docs folder. Hope it helps.

As user @aaracrr pointed out in a comment on another answer probably the best answer is to re-require the package with the same version constraint.
ie.
composer require vendor/package
or specifying a version constraint
composer require vendor/package:^1.0.0
You could actually just set the image of the UIButton
to what you would normally put in a UIImageView
. For example, where you would do:
myImageView.image = myUIImage
You could instead use:
myButton.setImage(myUIImage, forState: UIControlState.Normal)
So, here's what your code could look like:
override func viewDidLoad(){
super.viewDidLoad()
var myUIImage: UIImage //set the UIImage here
myButton.setImage(myUIImage, forState: UIControlState.Normal)
}
@IBOutlet var myButton: UIButton!
@IBAction func buttonTap(sender: UIButton!){
//handle the image tap
}
The great thing about using this method is that if you have to load the image from a database, you could set the title of the button before you set the image:
myButton.setTitle("Loading Image...", forState: UIControlState.Normal)
To tell your users that you are loading the image
This following works better if you need to scroll to an arbitrary item in the list (rather than always to the bottom):
function scrollIntoView(element, container) {
var containerTop = $(container).scrollTop();
var containerBottom = containerTop + $(container).height();
var elemTop = element.offsetTop;
var elemBottom = elemTop + $(element).height();
if (elemTop < containerTop) {
$(container).scrollTop(elemTop);
} else if (elemBottom > containerBottom) {
$(container).scrollTop(elemBottom - $(container).height());
}
}
They can be considered as equivalent. The limits in size are the same:
There is also the DBCLOBs, for double byte characters.

So, I tested above themes and found out none of them are showing proper color combination when using Productivity Power Tools in Visual Studio.
Ultimately, being a fan of dark themes, I created one myself which is fully supported from VS2005 to VS2013.
Here's the screenshot
Download this dark theme from here: Obsidian Meets Visual Studio
To use this theme go to Tools -> Import and Export Setting... -> import selected environment settings -> (optional to save current settings) -> Browse select and then Finish.
Do not forget to verify if your text editor encodes properly your code in UTF-8.
Otherwise, you may have invisible characters that are not interpreted as UTF-8.
Instead of adding the line breaks with nl2br() and then removing the line breaks with explode(), try using the line break character '\r' or '\n' or '\r\n'.
<?php $options= file_get_contents("employees.txt"); $options=explode("\n",$options); // try \r as well. foreach ($options as $singleOption){ echo "<option value='".$singleOption."'>".$singleOption."</option>"; } ?>
This could also fix the issue if the problem was due to Google Spreadsheets reading the line breaks.
You cannot 'alter' the property syntax this way. What you can do is this:
class Foo
{
string MyProperty { get; set; } // auto-property with inaccessible backing field
}
and a generic version would look like this:
class Foo<T>
{
T MyProperty { get; set; }
}
