I was looking into this because R was having issues installing into the default location and was instead just putting the packages into the temp folder. It turned out to be the latest update for Mcaffee Endpoint Security which apparently has issues with R. You can disable the threat protection while you install the packages and it will work properly.
What is wrong with the following code?
$a = 2;
function foo()
{
$a = 3;
}
foo();
echo $a;
You can just delete .git. Typically:
rm -rf .git
Then, recreate as the right user.
There is no tool specifically in the 'setup.exe' installer that offers the functionality of apt-get. There is, however, a command-line package installer for Cygwin that can be downloaded separately, but it is not entirely stable and relies on workarounds.

Try this:
$(document).on('click','#save',function(e) {
var data = $("#form-search").serialize();
$.ajax({
data: data,
type: "post",
url: "insertmail.php",
success: function(data){
alert("Data Save: " + data);
}
});
});
and in insertmail.php:
<?php
if(isset($_REQUEST))
{
mysql_connect("localhost","root","");
mysql_select_db("eciticket_db");
error_reporting(E_ALL && ~E_NOTICE);
$email=$_POST['email'];
$sql="INSERT INTO newsletter_email(email) VALUES ('$email')";
$result=mysql_query($sql);
if($result){
echo "You have been successfully subscribed.";
}
}
?>
Don't use mysql_
it's deprecated.
another method:
Actually if your problem is null value inserted into the database then try this and here no need of ajax.
<?php
if($_POST['email']!="")
{
mysql_connect("localhost","root","");
mysql_select_db("eciticket_db");
error_reporting(E_ALL && ~E_NOTICE);
$email=$_POST['email'];

$result=mysql_query($sql);
if($result){
//echo "You have been successfully subscribed.";
setcookie("msg","You have been successfully subscribed.",time()+5,"/");
header("location:yourphppage.php");
}
if(!$sql)
die(mysql_error());
mysql_close();
}
?>
<?php if(isset($_COOKIE['msg'])){?>
<span><?php echo $_COOKIE['msg'];setcookie("msg","",time()-5,"/");?></span>
<?php }?>
<form id="form-search" method="post" action="<?php echo $_SERVER['PHP_SELF'];?>">

If you want to filter on a grandchild (or deeper) of the given object, you can continue to build out your object hierarchy. For example, if you want to filter on 'thing.properties.title', you can do the following:
<div ng-repeat="thing in things | filter: { properties: { title: title_filter } }">
You can also filter on multiple properties of an object just by adding them to your filter object:
<div ng-repeat="thing in things | filter: { properties: { title: title_filter, id: id_filter } }">
For a div-Element you could just set the opacity via a class to enable or disable the effect.
.mute-all {
opacity: 0.4;
}
There is also a very helpful GUI tool called Product Browser which appears to be made by Microsoft or at least an employee of Microsoft.

Delete .android folder cache files, Also delete the build folder manually from a directory and open android studio and run again.
I had the same problem. Turns out the project I was referencing did not get build. When I went to the build configuration manager in visual studio and enabled the reference project , the issue got resolved.
You can use the zip()
and sort()
functions to accomplish this:
Python 2.6.5 (r265:79063, Jun 12 2010, 17:07:01)
[GCC 4.3.4 20090804 (release) 1] on cygwin
>>> list1 = [3,2,4,1,1]
>>> list2 = ['three', 'two', 'four', 'one', 'one2']
>>> zipped = zip(list1, list2)
>>> zipped.sort()
>>> slist1 = [i for (i, s) in zipped]
>>> slist1
[1, 1, 2, 3, 4]
>>> slist2 = [s for (i, s) in zipped]
>>> slist2
['one', 'one2', 'two', 'three', 'four']
Hope this helps
There shouldn't be any difference in gzip & deflate for decompression. Gzip is just deflate with a few dozen byte header wrapped around it including a checksum. The checksum is the reason for the slower compression. However when you're precompressing zillions of files you want those checksums as a sanity check in your filesystem. In addition you can utilize commandline tools to get stats on the file. For our site we are precompressing a ton of static data (the entire open directory, 13,000 games, autocomplete for millions of keywords, etc.) and we are ranked 95% faster than all websites by Alexa. Faxo Search. However, we do utilize a home grown proprietary web server. Apache/mod_deflate just didn't cut it. When those files are compressed into the filesystem not only do you take a hit for your file with the minimum filesystem block size but all the unnecessary overhead in managing the file in the filesystem that the webserver could care less about. Your concerns should be total disk footprint and access/decompression time and secondarily speed in being able to get this data precompressed. The footprint is important because even though disk space is cheap you want as much as possible to fit in the cache.
The "official" way to get the vs2015 is to go to https://my.visualstudio.com/ ; join the " Visual Studio Dev Essentials" and then search the relevant file to download https://my.visualstudio.com/Downloads?q=Visual%20Studio%202015%20with%20Update%203
This will not work:
wget -q -S -O - google.com 1>wget.txt 2>&1
since redirects are evaluated right to left, this sends html to wget.txt and the header to STDOUT:
wget -q -S -O - google.com 2>&1 1>wget.txt
Here is some text from MSDN about unmanaged code.
Some library code needs to call into unmanaged code (for example, native code APIs, such as Win32). Because this means going outside the security perimeter for managed code, due caution is required.
Here is some other complimentary explication about Managed code:
For your problem:
I think it's because NUnit execute your code for UnitTesting and might have some part of it that is unmanaged. But I am not sure about it, so do not take this for gold. I am sure someone will be able to give you more information about it. Hope it helps!
The only way to add any book marks in MobileSafari (including ones on the home screen) is with the builtin UI, and that Apples does not provide anyway to do this from scripts within a page. In fact, I am pretty sure there is no mechanism for doing this on the desktop version of Safari either.

Another solution without background image and without the need for a container (though the max sizes of the bounding box must be known):
img{
max-height: 100px;
max-width: 100px;
width: auto; /* These two are added only for clarity, */
height: auto; /* as the default is auto anyway */
}
img {
max-height: 100%;
max-width: 100%;
width: auto; /* These two are added only for clarity, */
height: auto; /* as the default is auto anyway */
}
div.container {
width: 100px;
height: 100px;
}
For this you would have something like:
<table>
<tr>
<td>Lorem</td>
<td>Ipsum<br />dolor</td>
<td>
<div class="container"><img src="image5.png" /></div>
</td>
</tr>
</table>

Invoking any method on any null reference will always result in an exception. Test if the object is null first:
List<Object> test = null;
if (test != null && !test.isEmpty()) {
// ...
}
Alternatively, write a method to encapsulate this logic:
public static <T> boolean IsNullOrEmpty(Collection<T> list) {
return list == null || list.isEmpty();
}
Then you can do:
List<Object> test = null;
if (!IsNullOrEmpty(test)) {
// ...
}
This could be complicated way of doing
String newString = new String(oldString);
This shortens the String is the underlying char[] used is much longer.
However more specifically it will be checking that every character can be UTF-8 encoded.
There are some "characters" you can have in a String which cannot be encoded and these would be turned into ?
Any character between \uD800 and \uDFFF cannot be encoded and will be turned into '?'
String oldString = "\uD800";
String newString = new String(oldString.getBytes("UTF-8"), "UTF-8");
System.out.println(newString.equals(oldString));
prints
false
Typically a .sh file is a shell script which you can execute in a terminal. Specifically, the script you mentioned is a bash script, which you can see if you open the file and look in the first line of the file, which is called the shebang or magic line.
You need to get hold of the axes themselves. Probably the cleanest way is to change your last row:
lm = sns.lmplot('X','Y',df,col='Z',sharex=False,sharey=False)
Then you can get hold of the axes objects (an array of axes):
axes = lm.axes
After that you can tweak the axes properties
axes[0,0].set_ylim(0,)
axes[0,1].set_ylim(0,)
creates:
You could do a simple calculation, pimped with an regex, if the chosen date format is 'YYYYMM':
echo $(($(date +"%Y%m") - 1)) | sed -e 's/99$/12/'
In January of 2020 it will return 201912 ;-) But, it's only a workaround, when date does not have calculation options and other dateinterpreter options (e.g. using perl) not available ;-)
I reached the point that I set, up to max_iter=1200000
on my LinearSVC
classifier, but still the "ConvergenceWarning" was still present. I fix the issue by just setting dual=False
and leaving max_iter
to its default.
With LogisticRegression(solver='lbfgs')
classifier, you should increase max_iter
. Mine have reached max_iter=7600
before the "ConvergenceWarning" disappears when training with large dataset's features.
I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.
Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled
Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is
Here is the xmlns reference:
xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI"
Then the ad itself:
<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480" AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/>
My issue was similar. This is what my experience has been on testing the IMG tag on gmail (assuming most of the organization's would have a dev qa and prod server.)
I had to send emails to customers on their personal email id's and we could see that gmail would add something of its own like following to src attribute of img tag. Now when we were sending these images from our dev environment they would never render on gmail and we were always curious why?
https://ci7.googleusercontent.com/proxy/AEF54znasdUhUYhuHuHuhHkHfT7u2w5zsOnWJ7k1MwrKe8pP69hY9W9eo8_n6-tW0KdSIaG4qaBEbcXue74nbVBysdfqweAsNNmmmJyTB-JQzcgn1j=s0-d-e2-ft#https://www.prodserver.com/Folder1/Images/OurImage.PNG
so an image sent to my gmail id as following never worked for me
<img src="https://ci7.googleuser....Blah.Blah..https://devserver.com/Folder1/Images/OurImage.PNG">
and our dev server we can't render this image by hitting following URL on Chrome(or any browser).
https://www.devserver.com/folder1/folder2/myactualimage.jpg
now as long as the src has www on it worked all the time and we didnt had to add any other attributes.
<img src="https://www.**prodserver**.com/folder1/folder2/myactualimage.jpg">
Just to clarify the answer given by JScoobyCed, the scp command cannot copy files to directories that require administrative permission. However, you can use the scp command to copy to directories that belong to the remote user.
So, to copy to a directory that requires root privileges, you must first copy that file to a directory belonging to the remote user using the scp command. Next, you must login to the remote account using ssh. Once logged in, you can then move the file to the directory of your choosing by using the sudo mv command. In short, the commands to use are as follows:
Using scp, copy file to a directory in the remote user's account, for example the Documents directory:
scp /path/to/your/local/file remoteUser@some_address:/home/remoteUser/Documents
Next, login to the remote user's account using ssh and then move the file to a restricted directory using sudo:
ssh remoteUser@some_address
sudo mv /home/remoteUser/Documents/file /var/www
If you are using drawableStart, drawableEnd, drawableTop or drawableBottom; you must use "setCompoundDrawablesRelativeWithIntrinsicBounds"

Instant.ofEpochSecond( 1_280_512_800L )
2010-07-30T18:00:00Z
The new java.time framework built into Java 8 and later is the successor to Joda-Time.
These new classes include a handy factory method to convert a count of whole seconds from epoch. You get an Instant
, a moment on the timeline in UTC with up to nanoseconds resolution.
Instant instant = Instant.ofEpochSecond( 1_280_512_800L );
instant.toString(): 2010-07-30T18:00:00Z
See that code run live at IdeOne.com.
Asia/Kabul
or Asia/Tehran
time zones ?You reported getting a time-of-day value of 22:30 instead of the 18:00 seen here. I suspect your PHP utility is implicitly applying a default time zone to adjust from UTC. My value here is UTC, signified by the Z
(short for Zulu
, means UTC). Any chance your machine OS or PHP is set to Asia/Kabul
or Asia/Tehran
time zones? I suppose so as you report IRST
in your output which apparently means Iran time. Currently in 2017 those are the only zones operating with a summer time that is four and a half hours ahead of UTC.
Specify a proper time zone name in the format of continent/region
, such as America/Montreal
, Africa/Casablanca
, or Pacific/Auckland
. Never use the 3-4 letter abbreviation such as EST
or IST
or IRST
as they are not true time zones, not standardized, and not even unique(!).
If you want to see your moment through the lens of a particular region's time zone, apply a ZoneId
to get a ZonedDateTime
. Still the same simultaneous moment, but seen as a different wall-clock time.
ZoneId z = ZoneId.of( "Asia/Tehran" ) ;
ZonedDateTime zdt = instant.atZone( z ); // Same moment, same point on timeline, but seen as different wall-clock time.
2010-07-30T22:30+04:30[Asia/Tehran]
You should stick with the new java.time classes. But you can convert to old if required.
java.util.Date date = java.util.Date.from( instant );
UPDATE: The Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes.
FYI, the constructor for a Joda-Time DateTime is similar: Multiply by a thousand to produce a long
(not an int
!).
DateTime dateTime = new DateTime( ( 1_280_512_800L * 1000_L ), DateTimeZone.forID( "Europe/Paris" ) );
Best to avoid the notoriously troublesome java.util.Date and .Calendar classes. But if you must use a Date, you can convert from Joda-Time.
java.util.Date date = dateTime.toDate();
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.*
classes.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
For more clarity on the answers given here, this is how you can use the extension functions. This is only if you are using Kotlin
If you are using com.squareup.okhttp3:okhttp:4.0.1
the older methods of creating objects of MediaType and RequestBody have been deprecated and cannot be used in Kotlin.
If you want to use the extension functions to get a MediaType object and a ResponseBody object from your strings, firstly add the following lines to the class in which you expect to use them.
import okhttp3.MediaType.Companion.toMediaType
import okhttp3.RequestBody.Companion.toRequestBody
You can now directly get an object of MediaType this way
val mediaType = "application/json; charset=utf-8".toMediaType()
To get an object of RequestBody first convert the JSONObject you want to send to a string this way. You have to pass the mediaType object to it.
val requestBody = myJSONObject.toString().toRequestBody(mediaType)
In the PHP version you can send 'true' in the last parameter, but the default is 'false'. The following algorithm is equivalent to the default PHP's hash function when passing 'sha256' as the first parameter:
public static string GetSha256FromString(string strData)
{
var message = Encoding.ASCII.GetBytes(strData);
SHA256Managed hashString = new SHA256Managed();
string hex = "";
var hashValue = hashString.ComputeHash(message);
foreach (byte x in hashValue)

hex += String.Format("{0:x2}", x);

There are all sorts of ways to get the Last Inserted ID but the easiest way I have found is by simply retrieving it from the TableAdapter in the DataSet like so:
<Your DataTable Class> tblData = new <Your DataTable Class>();
<Your Table Adapter Class> tblAdpt = new <Your Table Adapter Class>();
/*** Initialize and update Table Data Here ***/
/*** Make sure to call the EndEdit() method ***/
/*** of any Binding Sources before update ***/
<YourBindingSource>.EndEdit();
//Update the Dataset
tblAdpt.Update(tblData);
//Get the New ID from the Table Adapter
long newID = tblAdpt.Adapter.InsertCommand.LastInsertedId;
Hope this Helps ...
A little bit of decorator treatment (very loosely inspired by the Maybe monad and lifting). You can safely remove Python 3.6 type annotations and use an older message formatting style.
fallible.py
from functools import wraps
from typing import Callable, TypeVar, Optional
import logging
A = TypeVar('A')
def fallible(*exceptions, logger=None) \

:param logger: pass a custom logger; None means the default logger,
False disables logging altogether.
"""
def fwrap(f: Callable[..., A]) -> Callable[..., Optional[A]]:
@wraps(f)
def wrapped(*args, **kwargs):
try:
return f(*args, **kwargs)
except exceptions:
message = f'called {f} with *args={args} and **kwargs={kwargs}'
if logger:
logger.exception(message)
if logger is None:
logging.exception(message)
return None
return wrapped
return fwrap
Demo:

You can also modify this solution to return something a bit more meaningful than None
from the except
part (or even make the solution generic, by specifying this return value in fallible
's arguments).
If you project is at /home/forge/laravel-project/
You can properly execute your artisan like this
php /home/forge/laravel-project/artisan ...
You should probably use NOT EXISTS
for multiple columns.
Yes, they can throw exceptions. If so, they will only be partially initialized and if non-final, subject to attack.
The following is from the Secure Coding Guidelines 2.0.
Partially initialized instances of a non-final class can be accessed via a finalizer attack. The attacker overrides the protected finalize method in a subclass, and attempts to create a new instance of that subclass. This attempt fails (in the above example, the SecurityManager check in ClassLoader's constructor throws a security exception), but the attacker simply ignores any exception and waits for the virtual machine to perform finalization on the partially initialized object. When that occurs the malicious finalize method implementation is invoked, giving the attacker access to this, a reference to the object being finalized. Although the object is only partially initialized, the attacker can still invoke methods on it (thereby circumventing the SecurityManager check).
The classes which you are importing have to be on the classpath. So either the users of your Applet have to have the libraries in the right place or you simply provide those libraries by including them in your jar file. For example like this: Easiest way to merge a release into one JAR file
Yes you can. Example :
DELETE TableA
FROM TableA AS a
INNER JOIN TableB AS b
ON a.BId = b.BId
WHERE [filter condition]
If you're giving the same seed, that's normal. That's an important feature allowing tests.
Check this to understand pseudo random generation and seeds:
A pseudorandom number generator (PRNG), also known as a deterministic random bit generator DRBG, is an algorithm for generating a sequence of numbers that approximates the properties of random numbers. The sequence is not truly random in that it is completely determined by a relatively small set of initial values, called the PRNG's state, which includes a truly random seed.
If you want to have different sequences (the usual case when not tuning or debugging the algorithm), you should call the zero argument constructor which uses the nanoTime to try to get a different seed every time. This Random
instance should of course be kept outside of your method.
Your code should probably be like this:
private Random generator = new Random();
double randomGenerator() {
return generator.nextDouble()*0.5;
}
The jersey-container-servlet
actually uses the jersey-container-servlet-core
dependency. But if you use maven, that does not really matter. If you just define the jersey-container-servlet
usage, it will automatically download the dependency as well.
But for those who add jar files to their project manually (i.e. without maven) It is important to know that you actually need both jar files. The org.glassfish.jersey.servlet.ServletContainer
class is actually part of the core dependency.
Yup, there's the convert_tz

Using ES6,
you can use forEach
to iterate over the Keys of an Object.
To get all the keys you can use Object.keys
which returns all the keys in an Object
Object.keys(obj).forEach(function(keyValue, index, map) {
console.log(keyValue);
});
Short hand of the above snippet would be, which only takes one parameter
Object.keys(obj).forEach(function(keyValue) {
console.log(keyValue);
});

Got it to work go to the local.properties file under your build.gradle files to find out the PATH to your SDK, from the SDK location go into the platform-tools folder and look and see if you have adb.exe.
If not go to http://adbshell.com/downloads and download ADB KITS. Copy the zip folder's contents into the platform-tools folder and re-make your project.
I didn't need to update the PATH in the Extended Controls Settings section on the emulator, I left Use detected ADB location settings on. Hope this makes this faster for you !
You can implement your OTF
font using @font-face like:
@font-face {
font-family: GraublauWeb;
src: url("path/GraublauWeb.otf") format("opentype");
}
@font-face {
font-family: GraublauWeb;
font-weight: bold;
src: url("path/GraublauWebBold.otf") format("opentype");
}
// Edit: OTF now works in most browsers, see comments
However if you want to support a wide variety of browsers i would recommend you to switch to WOFF
and TTF
font types. WOFF
type is implemented by every major desktop browser, while the TTF
type is a fallback for older Safari, Android and iOS browsers. If your font is a free font, you could convert your font using for example a transfonter.
@font-face {
font-family: GraublauWeb;
src: url("path/GraublauWebBold.woff") format("woff"), url("path/GraublauWebBold.ttf") format("truetype");
}
If you want to support nearly every browser that is still out there (not necessary anymore IMHO), you should add some more font-types like:
@font-face {
font-family: GraublauWeb;
src: url("webfont.eot"); /* IE9 Compat Modes */
src: url("webfont.eot?#iefix") format("embedded-opentype"), /* IE6-IE8 */
url("webfont.woff") format("woff"), /* Modern Browsers */
url("webfont.ttf") format("truetype"), /* Safari, Android, iOS */
url("webfont.svg#svgFontName") format("svg"); /* Legacy iOS */
}
You can read more about why all these types are implemented and their hacks here. To get a detailed view of which file-types are supported by which browsers, see:
hope this helps
On linux you can use simple shell script https://github.com/dfsq/compressJS.sh to combine multiple javascript files into the single one. It makes use of the Closure Compiler online service so the resulting script is also effectively compressed.

}
Recognizes ftp://
, ftps://
, http://

I would also check the mysql configuration. I was running into this problem with my own server but I was a bit too hasty and misconfigured the innodb_buffer_pool_size for my machine.
innodb_buffer_pool_size = 4096M
It usually runs fine up to 2048 but I guess I don't have the memory necessary to support 4 gigs.
I imagine this could also happen with other mysql configuration settings.
You need to find the location of what you're looking for with .indexOf()
then remove it with .splice()
function remove(arr, what) {
var found = arr.indexOf(what);
while (found !== -1) {
arr.splice(found, 1);
found = arr.indexOf(what);
}
}
var array = new Array();
array.push("A");
array.push("B");
array.push("C");
?
remove(array, 'B');
alert(array)????;
This will take care of all occurrences.
I would implement a dialog asking the user if they wanted to exit and then call super.onBackPressed()
if they did.
@Override
public void onBackPressed() {
new AlertDialog.Builder(this)
.setTitle("Really Exit?")
.setMessage("Are you sure you want to exit?")
.setNegativeButton(android.R.string.no, null)
.setPositiveButton(android.R.string.yes, new OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
WelcomeActivity.super.onBackPressed();
}
}).create().show();
}
In the above example, you'll need to replace WelcomeActivity with the name of your activity.
You have to use escaping of characters. It's a solution of this chicken-and-egg problem: how do I write a ", if I need it to terminate a string literal? So, the C creators decided to use a special character that changes treatment of the next char:
printf("this is a \"quoted string\"");
Also you can use '\' to input special symbols like "\n", "\t", "\a", to input '\' itself: "\\" and so on.
Just replace following line
exec -a "$0" "$HERE/chrome" "$@"
with
exec -a "$0" "$HERE/chrome" "$@" --user-data-dir
all things will be right.
while (fscanf(input,"%s",arr) != EOF && count!=7) {
len=strlen(arr);
count++;
}
Use the id selector #
$('#passwordsNoMatchRegister').show();
For those interested in removing extension from filename, you can use https://nodejs.org/api/path.html#path_path_basename_path_ext
path.basename('/foo/bar/baz/asdf/quux.html', '.html');
FirebaseMessaging.getInstance().getToken().addOnSuccessListener(new
OnSuccessListener<String>() {

@Html.Raw(Json.Encode(object)) can be used to convert the View Modal Object to JSON
If you are using Windows PowerShell, the easiest way is to:
cat ~/.ssh/id_<key-type-here>.pub | clip
That will copy the key to your clipboard for easy pasting.
So, in my instance, I use ed25519 since RSA is now fairly hackable:
cat ~/.ssh/id_ed25519.pub | clip
Because I find myself doing this a lot, I created a function and set a simple alias I could remember in my PowerShell profile (learn more about PowerShell profiles here. Just add this to your Microsoft.PowerShell_profile.ps1
:
function Copy-SSHKey {
Get-Content ~/.ssh/id_ed25519.pub | clip
}
Set_Alias -Name sshkey -Value Copy-SSHKey
Then, in a PowerShell console, run . $profile
to load the functions. Then from now on all you will need to do is run sshkey
, and then paste the key into wherever you need via the clipboard.
Although this is not exactly what OP meant as this is not super simple, however, when running scripts from Notepad++ the os.getcwd()
method doesn't work as expected. This is what I would do:
import os
# get real current directory (determined by the file location)
curDir, _ = os.path.split(os.path.abspath(__file__))
print(curDir) # print current directory
Define a function like this:
def dir_up(path,n): # here 'path' is your path, 'n' is number of dirs up you want to go
for _ in range(n):
path = dir_up(path.rpartition("\\")[0], 0) # second argument equal '0' ensures that
# the function iterates proper number of times
return(path)
The use of this function is fairly simple - all you need is your path and number of directories up.
print(dir_up(curDir,3)) # print 3 directories above the current one
The only minus is that it doesn't stop on drive letter, it just will show you empty string.
you could use class for all your checkboxes, and do:
$(".check_class").click(function() {
$(".check_class").attr("checked", false); //uncheck all checkboxes
$(this).attr("checked", true); //check the clicked one
});
Just Modify your styles.xml
<!-- ActionBar styles -->

Kotlin Native:
memScoped {
val q = alloc<utsname>()
uname(q.ptr)
val identifier = NSString.stringWithCString(q.machine, encoding = NSUTF8StringEncoding)
}
You can do :
document.forms["loginForm"].submit()
But this won't call the onclick
action of your button, so you will need to call it by hand.
Be aware that you must use the name
of your form and not the id
to access it.
This is a simple solution with the function aggregate
:
aggregate(order_no ~ name, myvec, function(x) length(unique(x)))
Two options, either reference the new jars in your classpath or unpack all classes in the enclosing jars and re-jar the whole lot! As far as I know packaging jars within jars is not recommeneded and you'll forever have the class not found exception!
If you really must use jQuery to solve this problem (NB: you shouldn't):
(function($) {
$.rand = function(arg) {
if ($.isArray(arg)) {
return arg[$.rand(arg.length)];
} else if (typeof arg === "number") {
return Math.floor(Math.random() * arg);
} else {
return 4; // chosen by fair dice roll
}
};
})(jQuery);
var items = [523, 3452, 334, 31, ..., 5346];
var item = jQuery.rand(items);
This plugin will return a random element if given an array, or a value from [0 .. n) given a number, or given anything else, a guaranteed random value!
For extra fun, the array return is generated by calling the function recursively based on the array's length :)

Resizing the icon is not straightforward. You need to use Java's graphics 2D to scale the image. The first parameter is a Image class which you can easily get from ImageIcon
class. You can use ImageIcon
class to load your image file and then simply call getter method to get the image.
private Image getScaledImage(Image srcImg, int w, int h){
BufferedImage resizedImg = new BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB);
Graphics2D g2 = resizedImg.createGraphics();
g2.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
g2.drawImage(srcImg, 0, 0, w, h, null);
g2.dispose();
return resizedImg;
}
The tab character is \t
. Notice the use of "
instead of '
.
$chunk = "abc\tdef\tghi";
If the string is enclosed in double-quotes ("), PHP will interpret more escape sequences for special characters:
...
\t horizontal tab (HT or 0x09 (9) in ASCII)
Also, let me recommend the fputcsv() function which is for the purpose of writing CSV files.
The difference between test, [ and [[ is explained in great details in the BashFAQ.
To cut a long story short: test implements the old, portable syntax of the command. In almost all shells (the oldest Bourne shells are the exception), [ is a synonym for test (but requires a final argument of ]). Although all modern shells have built-in implementations of [, there usually still is an external executable of that name, e.g. /bin/[.
[[ is a new improved version of it, which is a keyword, not a program. This has beneficial effects on the ease of use, as shown below. [[ is understood by KornShell and BASH (e.g. 2.03), but not by the older POSIX or BourneShell.
And the conclusion:
When should the new test command [[ be used, and when the old one [? If portability to the BourneShell is a concern, the old syntax should be used. If on the other hand the script requires BASH or KornShell, the new syntax is much more flexible.
The query you want to show as an example is:
SELECT * FROM temp WHERE mydate > '2009-06-29 16:00:44';
04:00:00 is 4AM, so all the results you're displaying come after that, which is correct.
If you want to show everything after 4PM, you need to use the correct (24hr) notation in your query.
To make things a bit clearer, try this:
SELECT mydate, DATE_FORMAT(mydate, '%r') FROM temp;
That will show you the date, and its 12hr time.
The first answer is too complex, historic, and uninformative for my tastes.
It's actually rather simple. Docker provides for a functionality called multi-stage builds the basic idea here is to,
Let's start with the first. Very often with something like Debian you'll see.
RUN apt-get update \
&& apt-get dist-upgrade \
&& apt-get install <whatever> \
&& apt-get clean
We can explain all of this in terms of the above. The above command is chained together so it represents a single change with no intermediate Images required. If it was written like this,
RUN apt-get update ;
RUN apt-get dist-upgrade;
RUN apt-get install <whatever>;
RUN apt-get clean;
It would result in 3 more temporary intermediate Images. Having it reduced to one image, there is one remaining problem: apt-get clean
doesn't clean up artifacts used in the install. If a Debian maintainer includes in his install a script that modifies the system that modification will also be present in the final solution (see something like pepperflashplugin-nonfree
for an example of that).
By using a multi-stage build you get all the benefits of a single changed action, but it will require you to manually whitelist and copy over files that were introduced in the temporary image using the COPY --from
syntax documented here. Moreover, it's a great solution where there is no alternative (like an apt-get clean
), and you would otherwise have lots of un-needed files in your final image.

Turns out if you didn't install any SDK, Android Studio also shown "you haven't accept the license"...Such deceiving message, normal people would assume it implied SDK were already installed but anyway. In the Studio's SDK manager, you can just manually select the missing sdk to download and install and it handles license too. You just need to restart the Android Studio.

you can use:

In a git bash session, you can add a script to ~/.profile
or ~/.bashrc
(with ~
being usually set to %USERPROFILE%
), in order for said session to launch automatically the ssh-agent
. If the file doesn't exist, just create it.
This is what GitHub describes in "Working with SSH key passphrases".
The "Auto-launching ssh-agent on Git for Windows" section of that article has a robust script that checks if the agent is running or not. Below is just a snippet, see the GitHub article for the full solution.
# This is just a snippet. See the article above.
if ! agent_is_running; then
agent_start
ssh-add
elif ! agent_has_keys; then
ssh-add
fi
Other Resources:
"Getting ssh-agent to work with git run from windows command shell" has a similar script, but I'd refer to the GitHub article above primarily, which is more robust and up to date.
As an extra, you can take the Enum.Parse
answers already provided and put them in an easy-to-use static method in a helper class.
public static T ParseEnum<T>(string value)
{
return (T)Enum.Parse(typeof(T), value, ignoreCase: true);
}
And use it like so:
{
Content = ParseEnum<ContentEnum>(fileContentMessage);
};
Especially helpful if you have lots of (different) Enums to parse.
You can use this simple script to see commits that are not merged

# Show commits that exists only on branch and not in current
# Usage:
# git branch-notmerge <branchname>
#
# Setup git alias
# git config alias.branch-notmerge [path/to/this/script]
grep -Fvf <(git log --pretty=format:'%H - %s') <(git log $1 --pretty=format:'%H - %s')
You can use also tool git-wtf that will display state of branches
No. From the XHTML 1.0 Spec
In XML, fragment identifiers are of type ID, and there can only be a single attribute of type ID per element. Therefore, in XHTML 1.0 the id attribute is defined to be of type ID. In order to ensure that XHTML 1.0 documents are well-structured XML documents, XHTML 1.0 documents MUST use the id attribute when defining fragment identifiers on the elements listed above. See the HTML Compatibility Guidelines for information on ensuring such anchors are backward compatible when serving XHTML documents as media type text/html.
Whenever you are stuck in such type of problems, try to find the datatype of the element you want to convert first by using :
type(my_set)
Then, Use:
list(my_set)
to convert it to a list. You can use the newly built list like any normal list in python now.
If rather than the script, foo.R
, knowing its path location, if you can change your code to always reference all source
'd paths from a common root
then these may be a great help:
Given
/app/deeply/nested/foo.R
/app/other.R
This will work
#!/usr/bin/env Rscript
library(here)
source(here("other.R"))
See https://rprojroot.r-lib.org/ for how to define project roots.
billmanH's solution helped me but didn't work until i switched from:
n = data.loc[row,'json_column']
to:
n = data.iloc[[row]]['json_column']
here's the rest of it, converting to a dictionary is helpful for working with json data.
import json
for row in range(len(data)):
n = data.iloc[[row]]['json_column'].item()
jsonDict = json.loads(n)
if ('mykey' in jsonDict):
display(jsonDict['mykey'])
The paranoid version: Escaping every single character.
function javascript_escape($str) {
$new_str = '';
$str_len = strlen($str);
for($i = 0; $i < $str_len; $i++) {
$new_str .= '\\x' . sprintf('%02x', ord(substr($str, $i, 1)));
}
return $new_str;
}
EDIT: The reason why json_encode()
may not be appropriate is that sometimes, you need to prevent "
to be generated, e.g.
<div onclick="alert(???)" />
There is no defined maximum size for HTTP POST requests. If you notice such a limit then it's an arbitrary limitation of your HTTP Server/Client.
You might get a better answer if you tell how big the XML is.
var settings = new JsonSerializerSettings();
settings.ContractResolver = new CamelCasePropertyNamesContractResolver();
settings.NullValueHandling = NullValueHandling.Ignore;
//you can add multiple settings and then use it
var bodyAsJson = JsonConvert.SerializeObject(body, Formatting.Indented, settings);
I believe the following pdf will give you the bigger picture. Domain Driven Design by Eric Evans
NOTE: Think of a project you can work on, apply the little things you understood and see best practices. It will help you to grow your ability to the micro service architecture design approach too.
Add the following environment variable:
NODE_TLS_REJECT_UNAUTHORIZED=0

You can get the best of both worlds. It is possible to use ExternalProject
to download the gtest source and then use add_subdirectory()
to add it to your build. This has the following advantages:
Used in the normal way, ExternalProject won't do the download and unpacking at configure time (i.e. when CMake is run), but you can get it to do so with just a little bit of work. I've written a blog post on how to do this which also includes a generalised implementation which works for any external project which uses CMake as its build system, not just gtest. You can find them here:
Update: This approach is now also part of the googletest documentation.

Applying the DRY principle to Omar's solution, here's an HTML Helper extension:
using System.Web.Mvc;
using System.Text.RegularExpressions;
namespace System.Web.Mvc.Html {
public static class MyHtmlHelpers {
public static MvcHtmlString EncodedReplace(this HtmlHelper helper, string input, string pattern, string replacement) {
return new MvcHtmlString(Regex.Replace(helper.Encode(input), pattern, replacement));
}
}
}
Usage (with improved regex):
@Html.EncodedReplace(Model.CommentText, "[\n\r]+", "<br />")
This also has the added benefit of putting less onus on the Razor View developer to ensure security from XSS vulnerabilities.
My concern with Jacob's solution is that rendering the line breaks with CSS breaks the HTML semantics.
All too often a new developer asks this simple question which is a common problem specifically with Visual Studio IDE's. Few people answer the specific question and often critique the question or give "guesses" for solutions which don't answer the common problems. The first common problem is the IDE leads you to create new projects rather than add new files (.java, .py, .cpp, .c) to the existing solution (by default it creates a new solution) unless you change the project name and add to the current solution. This problem occurs for Python, java, c#, C++ and C project folders.
The new developer selecting "new>project>project name and changing the solution directory to "use same solution" still creates a new "project" in the same solution space, but not in the same directory space as the current user interface file or command line file which still leads to problems with "package not found" errors when building and running the project or solution. This is why the above coding suggestions to importing packages, classes, methods and functions only work (and thus don't answer the question) when the "library" file or "separate behavior" file is not only in the same solution directory path, but also in the same "user interface" or "command shell" application directory space. This does does not happen when you add another project using the new>project>project type commands of the IDE. The problem here is the new project is stored in a different directory than the existing Client or User interface code files. To create a new "file" in the same project space rather than new project the beginner needs to do the following that Microsoft won't do for you and even misleads you away from the intuitively obvious by default.
NOW the code recommendations to import libraries or using namespaces will work as described in the comments above and you don't have to change path statements or change solutions paths and solution names that Microsoft won't let you change easily (i.e. you can change the filenames or project names but the IDE won't automatically change the project path or the solution path names).
The following is a Python example but works similar for C#, java, or C/C++ using the includes, namespaces or using code commands appropriate to each language to find code in other classes/projects in the SAME DIRECTORY SPACE.
The application file "hello world" importing from other code files in the same directory.
Note the python white space delimiters are not going to space correctly in this stackoverflow comment editor:
print ("test")
from CIXMPythonFacade import ClassA
c1=ClassA
c1.methodA()
from CIXMPythonFacade import functionA
functionA()
class ClassName(object):
def __init__(object, parameter):
object.parameter = value
The library file or "façade" file containing classes, methods or functions you want to import.
class class1(object):
"""description of class"""
class ClassA(object):
print ("test2")
def methodA():
print ("test3")
def functionA ():
print ("test4")
return (0)
pass
NOW how do you actually solve the mess that the IDE leads you into? To import code from another file in the same directory space you add a reference to it.
OK so now that you have this problem solved, how do you really link two separate projects together in the same solution space?
Microsoft really, really needs to fix these problem so you can intuitively create what most people want to create as new files in the same directories and remove solutions by selecting them and deleting them from the IDE. Beginners get so frustrated with directory path statements so flexible for seasoned developers, but so unfair to new developers in their defaults.
Hope this really helps you new guys and stops seasoned developers from giving you the wrong answers that don't work for you. They assume you already understand path statements and just want to type the right code...which is also why the tunnel in on trying to correct your code but does not help you fix the problem. This is probably the most common problem continually described on stackoverflow with wrong answers that don't work for new programmers.
It sets how the database server sorts (compares pieces of text). in this case:
SQL_Latin1_General_CP1_CI_AS
breaks up into interesting parts:
latin1
makes the server treat strings using charset latin 1, basically asciiCP1
stands for Code Page 1252CI
case insensitive comparisons so 'ABC' would equal 'abc'AS
accent sensitive, so 'ü' does not equal 'u'P.S. For more detailed information be sure to read @solomon-rutzky's answer.
It contains your local IntelliJ IDE configs. I recommend adding this folder to your .gitignore

Google crawlers are not smart enough, they can't crawl relative URLs, that's why it's always recommended to use absolute URL's for better crawlability and indexability.
Therefore, you can not use this variation
> sitemap: /sitemap.xml
Recommended syntax is
Sitemap: https://www.yourdomain.com/sitemap.xml
Note:
If you only want to remove quotes from the beginning or the end, use the following regular expression:
'"Hello"'.replace(/(^"|"$)/g, '');
In bash scripts (non-interactive) by default JOB CONTROL is disabled so you can't do the the commands: job, fg, and bg.
Here is what works well for me:
#!/bin/sh
set -m # Enable Job Control
for i in `seq 30`; do # start 30 jobs in parallel
sleep 3 &
done
# Wait for all parallel jobs to finish
while [ 1 ]; do fg 2> /dev/null; [ $? == 1 ] && break; done
The last line uses "fg" to bring a background job into the foreground. It does this in a loop until fg returns 1 ($? == 1), which it does when there are no longer any more background jobs.

A test subject performs actions in response to certain prompts (function calls) or other stimuli. Here are concrete examples of test situations.
A student has studied to be an Emergency Medical Technician. Go watch Ian Gallagher in Shameless Season 6, Episode 10 if you are unfamiliar with this test situation.
It is too expensive to find patients with various illnesses for test purposes. Instead we use actors. We ask the test subject (Ian) "you arrive on the scene and the patient is immobilized and unconscious what do you do first?" Ian responds "I check if the scene is safe". And the test instructor says "the scene is safe".
The instructor (and actor) are able to inject arbitrary answers to the test subject's queries.
Here, the instructor (and actor) are a mock. Medical training uses this terminology (e.g. mock code simulation) the same as computer scientists.
You are testing Yahoo, a new email service you heard about. In order to sign up, you must provide your birthday and answers to other intrusive questions.

You can literally convert it into float using:
float_value = float(integer_value)
Likewise, you can convert an integer back to float datatype with:
integer_value = int(float_value)

Check out LiquiBase XML for keeping a changelog of updates. I had never used it until this year, but I found that it's very easy to learn and make DB revision control/migration/change management very foolproof. I work on a Groovy/Grails project, and Grails uses Hibernate underneath for all its ORM (called "GORM"). We use Liquibase to manage all SQL schema changes, which we do fairly often as our app evolves with new features.
Basically, you keep an XML file of changesets that you continue to add to as your application evolves. This file is kept in git (or whatever you are using) with the rest of your project. When your app is deployed, Liquibase checks it's changelog table in the DB you are connecting to so it will know what has already been applied, then it intelligently just applies whatever changesets have not been applied yet from the file. It works absolutely great in practice, and if you use it for all your schema changes, then you can be 100% confident that code you checkout and deploy will always be able to connect to a fully compatible database schema.
The awesome thing is that I can take a totally blank slate mysql database on my laptop, fire up the app, and right away the schema is set up for me. It also makes it easy to test schema changes by applying these to a local-dev or staging db first.
The easiest way to get started with it would probably be to take your existing DB and then use Liquibase to generate an initial baseline.xml file. Then in the future you can just append to it and let liquibase take over managing schema changes.
I deal with this issue for some hours. Let's consider the request is Reactjs (javascript) and backend (API) is Asp .Net Core.
in the request, you must set in header Content-Type:
Axios({
method: 'post',
headers: { 'Content-Type': 'application/json'},
url: 'https://localhost:44346/Order/Order/GiveOrder',
data: order,
}).then(function (response) {
console.log(response);
});
and in backend (Asp .net core API) u must have some setting:
1. in Startup --> ConfigureServices:
#region Allow-Orgin
services.AddCors(c =>
{
c.AddPolicy("AllowOrigin", options => options.AllowAnyOrigin());
});
#endregion
2. in Startup --> Configure before app.UseMvc() :
app.UseCors(builder => builder
.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader()
.AllowCredentials());
3. in controller before action:
[EnableCors("AllowOrigin")]
Quoted from CSS-Discuss Wiki
The @page rule has been cut down in scope from CSS2 to CSS2.1. The full CSS2 @page rule was reportedly implemented only in Opera (and buggily even then). My own testing shows that IE and Firefox don't support @page at all. According to the now-obsolescent CSS2 spec section 13.2.2 it is possible to override the user's setting of orientation and (for example) force printing in Landscape but the relevant "size" property has been dropped from CSS2.1, consistent with the fact that no current browser supports it. It has been reinstated in the CSS3 Paged Media module but note that this is only a Working Draft (as at July 2009).
Conclusion: forget about @page for the present. If you feel your document needs to be printed in Landscape orientation, ask yourself if you can instead make your design more fluid. If you really can't (perhaps because the document contains data tables with many columns, for example), you will need to advise the user to set the orientation to Landscape and perhaps outline how to do it in the most common browsers. Of course, some browsers have a print fit-to-width (shrink-to-fit) feature (e.g. Opera, Firefox, IE7) but it's inadvisable to rely on users having this facility or having it switched on.
I used this command to find last 5 minutes logs for particular event "DHCPACK

else {
print("Not found")

If you have this error while you create segues with the view controllers not with the UI elements you have to change sender: Any?
to this
@IBAction func backButtonPressed(_ sender: Any) {
performSegue(withIdentifier: "goToMainScreen", sender: self)
}
It will work.

I had this issue and found that the installation of the newer openssl
did actually work, but my PATH
was setup incorrectly for it -- my $PATH
had the ports path placed before my brew path so it always found the older version of openssl
.
The fix for me was to put the path to brew
(/usr/local/bin) at the front of my $PATH
.
To find out where you're loading openssl
from, run which openssl
and note the output. It will be the location of the version your system is using when you run openssl
. Its going to be somewhere other than the brew
path of "/usr/local/bin". Change your $PATH
, close that terminal tab and open a new one, and run which openssl
. You should see a different path now, probably under /usr/local/bin. Now run openssl version
and you should see the new version you installed "OpenSSL 1.0.1e 11 Feb 2013".
It is stretching because align-self default value is stretch. there is two solution for this case : 1. set img align-self : center OR 2. set parent align-items : center

This one is like the answer above which uses the MySql DATE_FORMAT() function. I also selected just one specific week in Jan.
SELECT
DatePart(day, DateAdded) AS date,

GROUP BY
DatePart(day, DateAdded )
At a guess, you used Code::Blocks to create a Console Application project. Such a project does not link in the GDI stuff, because console applications are generally not intended to do graphics, and TextOut
is a graphics function. If you want to use the features of the GDI, you should create a Win32 Gui Project, which will be set up to link in the GDI for you.
I see the picture, and all your classes are in the same package. So you don't have to import, you can create a new instance without the import sentence.
Use the ToString() method - standard and custom numeric format strings. Have a look at the MSDN article How to: Pad a Number with Leading Zeros.
string text = no.ToString("0000");
As a side note, the reason revoke usage on *.* from 'phpmyadmin'@'localhost';
does not work is quite simple : There is no grant called USAGE
.
The actual named grants are in the MySQL Documentation
The grant USAGE
is a logical grant. How? 'phpmyadmin'@'localhost' has an entry in mysql.user
where user='phpmyadmin' and host='localhost'. Any row in mysql.user semantically means USAGE
. Running DROP USER 'phpmyadmin'@'localhost';
should work just fine. Under the hood, it's really doing this:
DELETE FROM mysql.user WHERE user='phpmyadmin' and host='localhost';
DELETE FROM mysql.db WHERE user='phpmyadmin' and host='localhost';
FLUSH PRIVILEGES;
Therefore, the removal of a row from mysql.user
constitutes running REVOKE USAGE
, even though REVOKE USAGE
cannot literally be executed.
For Swift 3 and Xcode 8:
var dataTask: URLSessionDataTask?
if let url = URL(string: urlString) {
self.dataTask = URLSession.shared.dataTask(with: url, completionHandler: { (data, response, error) in
if let error = error {
print(error.localizedDescription)
} else if let httpResponse = response as? HTTPURLResponse, httpResponse.statusCode == 200 {
// You can use data received.
self.process(data: data as Data?)
}
})
}
}
//Note: You can always use debugger to check error
//How to use RedirectToAction in MVC
return RedirectToAction("actionName", "ControllerName", routevalue);
return RedirectToAction("Index", "Home", new { id = 2});
We also can use
import { Home } from './layouts/Home';
using export keyword before class keyword.
export class Home extends React.Component{
render(){
........
}
}
For default
import Home from './layouts/Home';
Default export class
export default class Home extends React.Component{
render(){
........
}
}
Both case don't need to write
export default Home;
after class.
According to your example here it seems that they both reside in the same namespace, i conclude that they are both part of the same project ( if you haven't created another project with the same namespace) and all class by default are defined as internal to the project they are defined in, if haven't declared otherwise, therefore i guess the problem is that your file is not included in your project. You can include it by right clicking the file in the solution explorer window => Include in project, if you cannot see the file inside the project files in the solution explorer then click the show the upper menu button of the solution explorer called show all files ( just hove your mouse cursor over the button there and you'll see the names of the buttons)
Just for basic knowledge: If the file resides in a different project\ assembly then it has to be defined, otherwise it has to be define at least as internal or public. in case your class is inheriting from that class that it can be protected as well.
You can try:
jar tvf jarfile.jar
This will be helpful only if your jar is executable i.e. in manifest you have defined some class as main class
The message you mention is quite clear:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
SLF4J API could not find a binding, and decided to default to a NOP implementation. In your case slf4j-log4j12.jar was somehow not visible when the LoggerFactory class was loaded into memory, which is admittedly very strange. What does "mvn dependency:tree" tell you?
The various dependency declarations may not even be directly at cause here. I strongly suspect that a pre-1.6 version of slf4j-api.jar
is being deployed without your knowledge.
This may seem obvious but just in case: If someone placed the JS code inside $(document).ready like this:
$(document).ready(function() {
... Google Maps JS code ...
}
Then that's the problem because using async
defer
when loading the Google Maps API library, it will load asynchronously, and when it finishes loading, will look for the callback function, which needs to be available by then.
So, you just need to put the code outside $(document).ready, and:
<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap"
async defer></script>
at the very bottom, so your page loads FAST :-)
Check this query in Athena for only one-space separated string (e.g. first name and middle name combination):
SELECT name, REVERSE( SUBSTR( REVERSE(name), 1, STRPOS(REVERSE(name), ' ') ) ) AS middle_name
FROM name_table
If you expect to have two or more spaces, you can easily extend the above query.

In my experience, the best way is right:0;
, left:0;
and margin:0 auto
. This way if the div is wide then you aren't hindered by the left: 50%;
that will offset your div which results in adding negative margins etc.
DEMO http://jsfiddle.net/kevinPHPkevin/DeTJH/4/
#logo {
background:red;
height:50px;
position:absolute;
width:50px;
margin:0 auto;
right:0;
left:0;
}
I'm using the J.S. to fix a sidebar menu. I've tried a lot of solutions with CSS but it's the simplest way to solve it, just add J.S. adding and removing a native BootStrap class: "position-fixed".
The J.S.:
var lateral = false;
function fixar() {
var element, name, arr;
element = document.getElementById("minhasidebar");
if (lateral) {
element.className = element.className.replace(
/\bposition-fixed\b/g, "");
lateral = false;
} else {
name = "position-fixed";
arr = element.className.split(" ");
if (arr.indexOf(name) == -1) {
element.className += " " + name;
}
lateral = true;
}
}
The HTML:
Sidebar:
<aside>
<nav class="sidebar ">
<div id="minhasidebar">
<ul class="nav nav-pills">
<li class="nav-item"><a class="nav-link active"
th:href="@{/hoje/inicial}"> <i class="oi oi-clipboard"></i>
<span>Hoje</span>
</a></li>
</ul>
</div>
</nav>
</aside>
It's fairly simple. You write values using keys and expiry times. You get values using keys. You can expire keys from the system.
Most clients follow the same rules. You can read the generic instructions and best practices on the memcached homepage.
If you really want to dig into it, I'd look at the source. Here's the header comment:
"""
client module for memcached (memory cache daemon)
Overview
========
See U{the MemCached homepage<http://www.danga.com/memcached>} for more about memcached.
Usage summary
=============
This should give you a feel for how this module operates::
import memcache
mc = memcache.Client(['127.0.0.1:11211'], debug=0)
mc.set("some_key", "Some value")
value = mc.get("some_key")
mc.set("another_key", 3)
mc.delete("another_key")
mc.set("key", "1") # note that the key used for incr/decr must be a string.
mc.incr("key")
mc.decr("key")
The standard way to use memcache with a database is like this::
key = derive_key(obj)
obj = mc.get(key)
if not obj:
obj = backend_api.get(...)
mc.set(key, obj)
# we now have obj, and future passes through this code
# will use the object from the cache.
Detailed Documentation
======================
More detailed documentation is available in the L{Client} class.
"""
With Spring Boot
its not necessary to have any config file like persistence.xml
. You can configure with annotations
Just configure your DB config for JPA in the
spring.datasource.driverClassName=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@DB...
spring.datasource.username=username
spring.datasource.password=pass
spring.jpa.database-platform=org.hibernate.dialect....
spring.jpa.show-sql=true
Then you can use CrudRepository
provided by Spring where you have standard CRUD
transaction methods. There you can also implement your own SQL's
like JPQL
.
@Transactional
public interface ObjectRepository extends CrudRepository<Object, Long> {
...
}
And if you still need to use the Entity Manager
you can create another class.
public class ObjectRepositoryImpl implements ObjectCustomMethods{
@PersistenceContext
private EntityManager em;
}
This should be in your pom.xml

I had a case very similar where I was posting in an each loop and then setting the html markup in some fields from numbers received from the ajax. I then needed to do a sum of the (now-updated) values of these fields and place in a total field.
Thus the problem was that I was trying to do a sum on all of the numbers but no data had arrived back yet from the async ajax calls. I needed to complete this functionality in a few functions to be able to reuse the code. My outer function awaits the data before I then go and do some stuff with the fully updated DOM.
// 1st
function Outer() {
var deferreds = GetAllData();
$.when.apply($, deferreds).done(function () {
// now you can do whatever you want with the updated page
});
}
// 2nd
function GetAllData() {
var deferreds = [];
$('.calculatedField').each(function (data) {
deferreds.push(GetIndividualData($(this)));
});
return deferreds;
}
// 3rd
function GetIndividualData(item) {
var def = new $.Deferred();
$.post('@Url.Action("GetData")', function (data) {
item.html(data.valueFromAjax);
def.resolve(data);
});
return def;
}
The easiest is setting a program variable (see GDB: assignment):
(gdb) l
6 {
7 int i;
8 struct file *f, *ftmp;
9
(gdb) set variable i = 10
(gdb) p i
$1 = 10
Or you can just update arbitrary (writable) location by address:
(gdb) set {int}0x83040 = 4
There's more. Read the manual.
the problem is in url pattern of servlet-mapping.
<url-pattern>/DispatcherServlet</url-pattern>
let's say our controller is
@Controller
public class HomeController {
@RequestMapping("/home")
public String home(){
return "home";
}
}
when we hit some URL on our browser. the dispatcher servlet will try to map this url.
the url pattern of our serlvet currently is /Dispatcher
which means resources are served from {contextpath}/Dispatcher
but when we request http://localhost:8080/home
we are actually asking resources from /
which is not available.
so either we need to say dispatcher servlet to serve from /
by doing
<url-pattern>/</url-pattern>
our make it serve from /Dispatcher by doing /Dispatcher/*
E.g
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://xmlns.jcp.org/xml/ns/javaee"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID"
version="3.1">
<display-name>springsecuritydemo</display-name>
<servlet>
<description></description>
<display-name>offers</display-name>
<servlet-name>offers</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>offers</servlet-name>
<url-pattern>/Dispatcher/*</url-pattern>
</servlet-mapping>
</web-app>
and request it with http://localhost:8080/Dispatcher/home
or put just /
to request like
http://localhost:8080/home
I just installed Fedora 16 (yea, I know it's old and not supported but, I had the CD burnt :) )
Anyway, coming to the solution, this is what I was required to do:
su -
gedit /etc/phpMyAdmin/config.inc.php
if not found... try phpmyadmin - all small caps.
gedit /etc/phpmyadmin/config.inc.php
Locate
$cfg['Servers'][$i]['AllowNoPassword']
and set it to:
$cfg['Servers'][$i]['AllowNoPassword'] = TRUE;
Save it.
EasyCharts is commercial so i couldn't use it for my project. I used the GRAL graphing library instead. I found it very easy to customize and it's licensed under LGPL just like JFreeChart, so you can use it for free:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.example.app"
tools:ignore="GoogleAppIndexingWarning">
You can remove the warning by adding xmlns:tools="http://schemas.android.com/tools"
and tools:ignore="GoogleAppIndexingWarning"
to the <manifest>
tag.
Here is a concise breadth-first iterative solution, which I prefer to recursion:
const findCar = function(car) {
const carSearch = [cars];
while(carSearch.length) {
let item = carSearch.shift();
if (item.label === car) return true;
carSearch.push(...item.subs);
}
return false;
}

just create new android project and copy paste my code and have fun! :) also remember in xml i have image view and his background images replace with yout own images thanks..
If you are reading special files like stdin or a pipe, you are not going to be able to use fstat to get the file size beforehand. Also, if you are reading a binary file fgets is going to lose the string size information because of embedded '\0' characters. Best way to read a file then is to use read and realloc:
#include <stdio.h>
#include <unistd.h>
#include <errno.h>
#include <string.h>
int main () {
char buf[4096];
ssize_t n;
char *str = NULL;
size_t len = 0;
while (n = read(STDIN_FILENO, buf, sizeof buf)) {
if (n < 0) {
if (errno == EAGAIN)
continue;
perror("read");
break;
}
str = realloc(str, len + n + 1);
memcpy(str + len, buf, n);
len += n;
str[len] = '\0';
}
printf("%.*s\n", len, str);
return 0;
}
You can experiment with the native DB driver for Excel in language/platform of your choice. In Java world, you can try with http://code.google.com/p/sqlsheet/ which provides a JDBC driver for working with Excel sheets directly. Similarly, you can get drivers for the DB technology for other platforms.
However, I can guarantee that you will soon hit a wall with the number of features these wrapper libraries provide. Better way will be to use Apache HSSF/POI or similar level of library but it will need more coding effort.
Here is another way to iterate over the properties:
Enumeration eProps = properties.propertyNames();
while (eProps.hasMoreElements()) {
String key = (String) eProps.nextElement();
String value = properties.getProperty(key);
System.out.println(key + " => " + value);
}
Here I am giving you a proper example of one callback method . so suppose we have a method like method login() :
public void login() {
loginService = new LoginService();
loginService.login(loginProvider, new LoginListener() {
@Override
public void onLoginSuccess() {
loginService.getresult(true);
}
@Override
public void onLoginFaliure() {
loginService.getresult(false);
}
});
System.out.print("@@##### get called");
}
I also put all the helper class here to make the example more clear: loginService class
public class LoginService implements Login.getresult{
public void login(LoginProvider loginProvider,LoginListener callback){
String username = loginProvider.getUsername();
String pwd = loginProvider.getPassword();
if(username != null && pwd != null){
callback.onLoginSuccess();
}else{
callback.onLoginFaliure();
}
}
@Override
public void getresult(boolean value) {
System.out.print("login success"+value);
}}
and we have listener LoginListener as :
interface LoginListener {
void onLoginSuccess();
void onLoginFaliure();
}
now I just wanted to test the method login() of class Login
@Test
public void loginTest() throws Exception {
LoginService service = mock(LoginService.class);
LoginProvider provider = mock(LoginProvider.class);
whenNew(LoginProvider.class).withNoArguments().thenReturn(provider);
whenNew(LoginService.class).withNoArguments().thenReturn(service);
when(provider.getPassword()).thenReturn("pwd");
when(provider.getUsername()).thenReturn("username");
login.getLoginDetail("username","password");
verify(provider).setPassword("password");
verify(provider).setUsername("username");
verify(service).login(eq(provider),captor.capture());
LoginListener listener = captor.getValue();
listener.onLoginSuccess();
verify(service).getresult(true);
also dont forget to add annotation above the test class as
@RunWith(PowerMockRunner.class)
@PrepareForTest(Login.class)
cat find_replace | while read pattern replacement ; do
sed -i "/${pattern}/c ${replacement}" file
done
find_replace file contains 2 columns, c1 with pattern to match, c2 with replacement, the sed loop replaces each line conatining one of the pattern of variable 1
you use script in php..
<?php
$num = 1;
echo $num;
echo '<input type="button"
name="lol"
value="Click to increment"
onclick="Inc()" />
<br>
<script>
function Inc()
{';
$num = 2;
echo $num;
echo '}
</script>';
?>
You can create a one-way hash with bcrypt using PHP's crypt()
function and passing in an appropriate Blowfish salt. The most important of the whole equation is that A) the algorithm hasn't been compromised and B) you properly salt each password. Don't use an application-wide salt; that opens up your entire application to attack from a single set of Rainbow tables.

One possible option is to use itertools.cycle()
, which will allow you to iterate indefinitely without any trick like .seek(0)
.
iterDic = itertools.cycle(csv.DictReader(open('file.csv')))
Adding my localhost on Valid OAuth redirect URIs at https://developers.facebook.com/apps/YOUR_APP_ID/fb-login/ solved the problem!
And pay attention for one detail here:
In this case http://localhost:3000 is not the same of http://0.0.0.0:3000 or http://127.0.0.1:3000
Make sure you are using exactly the running url of you sandbox server. I spend some time to discover that...
There are various scripts floating around that will do that depending on how crazy you want to get. I would personally use Pete Finnigan's find_all_privs script.
If you want to write it yourself, the query gets rather challenging. Users can be granted system privileges which are visible in DBA_SYS_PRIVS
. They can be granted object privileges which are visible in DBA_TAB_PRIVS
. And they can be granted roles which are visible in DBA_ROLE_PRIVS
(roles can be default or non-default and can require a password as well, so just because a user has been granted a role doesn't mean that the user can necessarily use the privileges he acquired through the role by default). But those roles can, in turn, be granted system privileges, object privileges, and additional roles which can be viewed by looking at ROLE_SYS_PRIVS
, ROLE_TAB_PRIVS
, and ROLE_ROLE_PRIVS
. Pete's script walks through those relationships to show all the privileges that end up flowing to a user.
In addition to the previous response, the best option to submit a form with different buttons without language problems is actually using a button tag.
<form>
...
<button type="submit" name="submit" value="servlet1">Go to 1st Servlet</button>
<button type="submit" name="submit" value="servlet2">Go to 2nd Servlet</button>
</form>
I cloned the following: https://github.com/google/play-licensing
Then I imported that into my project.
Steps (1) Just Select your range, rows or column or array , (2) Press ctrl+H , (3 a) then in the find type a space (3 b) in the replace do not enter anything, (4)then just click on replace all..... you are done.
add \ before special characters:
s/\?page=one&/page\/one\//g
etc.
in a Visual Basic Macro you would use
pName = ActiveWorkbook.Path ' the path of the currently active file
wbName = ActiveWorkbook.Name ' the file name of the currently active file
shtName = ActiveSheet.Name ' the name of the currently selected worksheet
The first sheet in a workbook can be referenced by
ActiveWorkbook.Worksheets(1)
so after deleting the [Report] tab you would use
ActiveWorkbook.Worksheets("Report").Delete
shtName = ActiveWorkbook.Worksheets(1).Name
to "work on that sheet later on" you can create a range object like
Dim MySheet as Range
MySheet = ActiveWorkbook.Worksheets(shtName).[A1]
and continue working on MySheet(rowNum, colNum)
etc. ...
shortcut creation of a range object without defining shtName:
Dim MySheet as Range
MySheet = ActiveWorkbook.Worksheets(1).[A1]
Once an instance has been started, there is no way to change the keypair associated with the instance at a meta data level, but you can change what ssh key you use to connect to the instance.

There are two ways to access properties of objects:
var obj = {a: 'foo', b: 'bar'};
obj.a //foo
obj['b'] //bar
Or, if you need to dynamically do it:
var key = 'b';
obj[key] //bar
If you don't already have it as an object, you'll need to convert it.
For a more complex example, let's assume you have an array of objects that represent users:
var users = [{name: 'Corbin', age: 20, favoriteFoods: ['ice cream', 'pizza']},
{name: 'John', age: 25, favoriteFoods: ['ice cream', 'skittle']}];
To access the age property of the second user, you would use users[1].age
. To access the second "favoriteFood" of the first user, you'd use users[0].favoriteFoods[2]
.
Another example: obj[2].key[3]["some key"]
That would access the 3rd element of an array named 2. Then, it would access 'key' in that array, go to the third element of that, and then access the property name some key
.
As Amadan noted, it might be worth also discussing how to loop over different structures.
To loop over an array, you can use a simple for loop:
var arr = ['a', 'b', 'c'],
i;
for (i = 0; i < arr.length; ++i) {
console.log(arr[i]);
}
To loop over an object is a bit more complicated. In the case that you're absolutely positive that the object is a plain object, you can use a plain for (x in obj) { }
loop, but it's a lot safer to add in a hasOwnProperty check. This is necessary in situations where you cannot verify that the object does not have inherited properties. (It also future proofs the code a bit.)
var user = {name: 'Corbin', age: 20, location: 'USA'},
key;
for (key in user) {
if (user.hasOwnProperty(key)) {
console.log(key + " = " + user[key]);
}
}
(Note that I've assumed whatever JS implementation you're using has console.log
. If not, you could use alert
or some kind of DOM manipulation instead.)
Update February 2016:
www.javadecompilers.com lists JAD as being:
the most popular Java decompiler, but primarily of this age only. Written in C++, so very fast.
Outdated, unsupported and does not decompile correctly Java 5 and later
So your mileage may vary with recent jdk (7, 8).
The same site list other tools.
And javadecompiler, as noted by Salvador Valencia in the comments (Sept 2017), offers a SaaS where you upload the .class
file to the cloud and it returns you the decompiled code.
Original answer: Oct. 2008
Java Decompiler (Yet another Fast Java decompiler) has:
It works with compilers from JDK 1.1.8 up to JDK 1.7.0, and others (Jikes, JRockit, etc.).
It features an online live demo version that is actually fully functional! You can just drop a jar file on the page and see the decompiled source code without installing anything.
We can use arrayUnion({})
method to achive this.
Try this:
collectionRef.doc(ID).update({
sharedWith: admin.firestore.FieldValue.arrayUnion({
who: "[email protected]",
when: new Date()
})
});
Documentation can find here: https://firebase.google.com/docs/firestore/manage-data/add-data#update_elements_in_an_array
your first try is using declarative pipelines, and the second working one is using scripted pipelines. you need to enclose steps in a steps declaration, and you can't use if
as a top-level step in declarative, so you need to wrap it in a script
step. here's a working declarative version:
pipeline {
agent any
stages {
stage('test') {
steps {
sh 'echo hello'
}
}
stage('test1') {
steps {
sh 'echo $TEST'
}
}
stage('test3') {
steps {
script {
if (env.BRANCH_NAME == 'master') {
echo 'I only execute on the master branch'
} else {
echo 'I execute elsewhere'
}
}
}
}
}
}
you can simplify this and potentially avoid the if statement (as long as you don't need the else) by using "when". See "when directive" at https://jenkins.io/doc/book/pipeline/syntax/. you can also validate jenkinsfiles using the jenkins rest api. it's super sweet. have fun with declarative pipelines in jenkins!
Your arguments are in the wrong order. The connection comes first according to the docs
<?php
require("constants.php");
// 1. Create a database connection
$connection = mysqli_connect(DB_SERVER,DB_USER,DB_PASS);
if (!$connection) {
error_log("Failed to connect to MySQL: " . mysqli_error($connection));
die('Internal server error');
}
// 2. Select a database to use
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
error_log("Database selection failed: " . mysqli_error($connection));
die('Internal server error');
}
?>
A generic piece of code that will work for multiple columns. This can also be used if there is a need to conditionally implement search functionality in the application.
search_key = "abc"
search_args = [col.ilike('%%%s%%' % search_key) for col in ['col1', 'col2', 'col3']]
query = Query(table).filter(or_(*search_args))
session.execute(query).fetchall()
Note: the %%
are important to skip % formatting the query.
On mac, open the terminal and type:
cd /usr/local/mysql/bin
then type:
./mysql -u root -p
It will ask you for the mysql root password. Enter your password and use mysql database in the terminal.
Most code I've seen is camelCase
functions (lower case initial letter), and ProperCase/PascalCase
class names, and (most usually), snake_case
variables.
But, to be honest, this is all just guidance. The single most important thing is to be consistent across your code base. Pick what seems natural / works for you, and stick to it. If you're joining a project in progress, follow their standards.
I would use this syntax. It achives the same as Josh and Chris's suggestions, but with the advantage it is ANSI complient and not tied to a particular database vendor.

I had the same problem and got it resolved by deleting .m2 maven repo (C:\Users\user\ .m2)
There is a (somewhat) related question on StackOverflow:
Here the problem was that an array of shape (nx,ny,1) is still considered a 3D array, and must be squeeze
d or sliced into a 2D array.
More generally, the reason for the Exception
TypeError: Invalid dimensions for image data
is shown here: matplotlib.pyplot.imshow()
needs a 2D array, or a 3D array with the third dimension being of shape 3 or 4!
You can easily check this with (these checks are done by imshow
, this function is only meant to give a more specific message in case it's not a valid input):
from __future__ import print_function
import numpy as np
def valid_imshow_data(data):
data = np.asarray(data)
if data.ndim == 2:
return True
elif data.ndim == 3:
if 3 <= data.shape[2] <= 4:
return True
else:
print('The "data" has 3 dimensions but the last dimension '
'must have a length of 3 (RGB) or 4 (RGBA), not "{}".'
''.format(data.shape[2]))
return False
else:
print('To visualize an image the data must be 2 dimensional or '
'3 dimensional, not "{}".'
''.format(data.ndim))
return False
In your case:
>>> new_SN_map = np.array([1,2,3])
>>> valid_imshow_data(new_SN_map)
To visualize an image the data must be 2 dimensional or 3 dimensional, not "1".
False
The np.asarray
is what is done internally by matplotlib.pyplot.imshow
so it's generally best you do it too. If you have a numpy array it's obsolete but if not (for example a list
) it's necessary.
In your specific case you got a 1D array, so you need to add a dimension with np.expand_dims()
import matplotlib.pyplot as plt
a = np.array([1,2,3,4,5])
a = np.expand_dims(a, axis=0) # or axis=1
plt.imshow(a)
plt.show()
or just use something that accepts 1D arrays like plot
:
a = np.array([1,2,3,4,5])
plt.plot(a)
plt.show()
From version 9.1.4 you only need to import ReactiveFormsModule
I would add another column on the data sheet with equation =month(A2), then run the countif on that column... If you still wanted to use text month('APRIL'), you would need a lookup table to reference the name to the month number. Otherwise, just use 4 instead of April on your metric sheet.
Through PCRE verb (*SKIP)(*F)
^hede$(*SKIP)(*F)|^.*$
This would completely skips the line which contains the exact string hede
and matches all the remaining lines.
Execution of the parts:
Let us consider the above regex by splitting it into two parts.
Part before the |
symbol. Part shouldn't be matched.
^hede$(*SKIP)(*F)
Part after the |
symbol. Part should be matched.
^.*$
PART 1
Regex engine will start its execution from the first part.
^hede$(*SKIP)(*F)
Explanation:
^
Asserts that we are at the start.hede
Matches the string hede
$
Asserts that we are at the line end.So the line which contains the string hede
would be matched. Once the regex engine sees the following (*SKIP)(*F)
(Note: You could write (*F)
as (*FAIL)
) verb, it skips and make the match to fail. |
called alteration or logical OR operator added next to the PCRE verb which inturn matches all the boundaries exists between each and every character on all the lines except the line contains the exact string hede
. See the demo here. That is, it tries to match the characters from the remaining string. Now the regex in the second part would be executed.
PART 2
^.*$
Explanation:
^
Asserts that we are at the start. ie, it matches all the line starts except the one in the hede
line. See the demo here..*
In the Multiline mode, .
would match any character except newline or carriage return characters. And *
would repeat the previous character zero or more times. So .*
would match the whole line. See the demo here.
Hey why you added .* instead of .+ ?
Because .*
would match a blank line but .+
won't match a blank. We want to match all the lines except hede
, there may be a possibility of blank lines also in the input . so you must use .*
instead of .+
. .+
would repeat the previous character one or more times. See .*
matches a blank line here.
$
End of the line anchor is not necessary here.

From Hadoop page,
start-all.sh
This will startup a Namenode, Datanode, Jobtracker and a Tasktracker on your machine.
start-dfs.sh
This will bring up HDFS with the Namenode running on the machine you ran the command on. On such a machine you would need start-mapred.sh
to separately start the job tracker
start-all.sh/stop-all.sh
has to be run on the master node
You would use start-all.sh
on a single node cluster (i.e. where you would have all the services on the same node.The namenode is also the datanode and is the master node).
In multi-node setup,
You will use start-all.sh
on the master node and would start what is necessary on the slaves as well.
Alternatively,
Use start-dfs.sh
on the node you want the Namenode to run on. This will bring up HDFS with the Namenode running on the machine you ran the command on and Datanodes on the machines listed in the slaves file.
Use start-mapred.sh
on the machine you plan to run the Jobtracker on. This will bring up the Map/Reduce cluster with Jobtracker running on the machine you ran the command on and Tasktrackers running on machines listed in the slaves file.
hadoop-daemon.sh
as stated by Tariq is used on each individual node. The master node will not start the services on the slaves.In a single node setup this will act same as start-all.sh
.In a multi-node setup you will have to access each node (master as well as slaves) and execute on each of them.
Have a look at this start-all.sh
it call config followed by dfs and mapred
You can run JMeter from the command line using the -n parameter for 'Non-GUI' and the -t parameter for the test plan file.
jmeter -n -t "PATHTOJMXFILE"
If you want to further customize the command line experience, I would direct you to the 'Getting Started' section of their documentation.
You already have a version of mySQL installed on this machine that is using port 3306. Go into the most recent my.ini
file and change the port to 3307
. Restart the mySQL service and see if it comes up.
You also need to change port 3306 to 3307 in xampp\php\php.ini
Also, your compare function is incorrect. It needs to return -1, 0, or 1, not a boolean as you have it. The correct compare function would be:
def compare(item1, item2):
if fitness(item1) < fitness(item2):
return -1
elif fitness(item1) > fitness(item2):
return 1
else:
return 0

Try this
public ActionResult CreatePerson(string Enc)
window.location = '@Url.Action("CreatePerson", "Person", new { Enc = "id", actionType = "Disable" })'.replace("id", id).replace("&", "&");
you will get the id inside the Enc string.

For Java:
public class Constants {
public static final long MAX_CLICK_INTERVAL = 1000;}
Equivalent Kotlin code:
object Constants {
const val MAX_CLICK_INTERVAL: Long = 1000}
So for the equivalent of Java static methods is object class in Kotlin.

char a[2]
defines an array of char
's. a
is a pointer to the memory at the beginning of the array and using ==
won't actually compare the contents of a
with 'ab'
because they aren't actually the same types, 'ab'
is integer type. Also 'ab'
should be "ab"
otherwise you'll have problems here too. To compare arrays of char you'd want to use strcmp.
Something that might be illustrative is looking at the typeid
of 'ab'
:
#include <iostream>
#include <typeinfo>
using namespace std;
int main(){
int some_int =5;
std::cout << typeid('ab').name() << std::endl;
std::cout << typeid(some_int).name() << std::endl;
return 0;
}
on my system this returns:
i
i
showing that 'ab'
is actually evaluated as an int.
If you were to do the same thing with a std::string then you would be dealing with a class and std::string has operator ==
overloaded and will do a comparison check when called this way.
If you wish to compare the input with the string "ab" in an idiomatic c++ way I suggest you do it like so:
#include <iostream>
#include <string>
using namespace std;
int main(){
string a;
cout<<"enter ab ";
cin>>a;
if(a=="ab"){
cout<<"correct";
}
return 0;
}
This one is due to:
if(a=='ab')
, here, a
is const char*
type (ie : array of char)
'ab'
is a constant value,which isn't evaluated as string (because of single quote) but will be evaluated as integer.
Since char
is a primitive type inherited from C, no operator ==
is defined.
the good code should be:
if(strcmp(a,"ab")==0)
, then you'll compare a const char*
to another const char*
using strcmp
.
