using PhpMyAdmin version 4.5.4.1deb2ubuntu2, you can set the variables in /etc/phpmyadmin/config-db.php
so set $dbserver
to your server name, e.g. $dbserver='mysql.example.com';
<?php
##
## database access settings in php format
## automatically generated from /etc/dbconfig-common/phpmyadmin.conf
## by /usr/sbin/dbconfig-generate-include
##
## by default this file is managed via ucf, so you shouldn't have to
## worry about manual changes being silently discarded. *however*,
## you'll probably also want to edit the configuration file mentioned
## above too.
##
$dbuser='phpmyadmin';
$dbpass='P@55w0rd';
$basepath='';
$dbname='phpmyadmin';
$dbserver='localhost';
$dbport='';
$dbtype='mysql';
The closest thing to PHP's var_dump()
is pprint()
with the getmembers()
function in the built-in inspect
module:
from inspect import getmembers
from pprint import pprint
pprint(getmembers(yourObj))
At first install necessary PDO parts by running the command
`sudo apt-get install php*-mysql`
where * is a version name of php like 5.6, 7.0, 7.1, 7.2
After installation you need to mention these two statements
extension=pdo.so
extension=pdo_mysql.so
in your .ini file (uncomment if it is already there) and restart server by command
sudo service apache2 restart
Withough testing, I'd try:
for c in session.query(Stuff).all():
c.foo = c.foo+1
session.commit()
(IIRC, commit() works without flush()).
I've found that at times doing a large query and then iterating in python can be up to 2 orders of magnitude faster than lots of queries. I assume that iterating over the query object is less efficient than iterating over a list generated by the all() method of the query object.
[Please note comment below - this did not speed things up at all].
I think cURL doesn't work with WAMP 2.2e. I tried all your solutions, but it still did not work. I got the previous version, (2.2d) and it works.
So just download the previous version :D
This got it working for me:
:set tabstop=2 shiftwidth=2 expandtab | retab
When using Windows, the comparison is cut short: memcache
appears to be the only client available.
In my case this problem occured after updating Java from 1.6 to 1.7.
To understand the error, run java.exe in the folder of eclipse.exe
. Use parameters from eclipse.ini as it will show which parameter causes the failure.
For example:
F:\Mobile Class\adt-bundle-windows-x86\adt-bundle-windows-x86\eclipse>java -star

How about
a["abc"] = [1, 2]
This will result in:
>>> a
{'abc': [1, 2]}
Is that what you were looking for?
After running into the same issue - here're some of my thoughts:
As it affects only Chrome (other browsers work fine with VideoForEverybody solution) the solution I've used is:
for every mp4 file, create a Theora encoded mp4 file (example.mp4 -> example_c.mp4) apply following js:
if (window.chrome)
$("[type=video\\\/mp4]").each(function()
{
$(this).attr('src', $(this).attr('src').replace(".mp4", "_c.mp4"));
});
Unfortunately it's a bad Chrome hack, but hey, at least it works.
Source: user: eithedog
This also can help: chrome could play html5 mp4 video but html5test said chrome did not support mp4 video codec
Also check your version of crome here: html5test
Very similar to Holger's answer. If you need to grab the URL can do something like:
Uri uri = Context.Request.Url;
var scheme = uri.Scheme // returns http, https
var scheme2 = uri.Scheme + Uri.SchemeDelimiter; // returns http://, https://
var host = uri.Host; // return www.mywebsite.com
var port = uri.Port; // returns port number
The Uri class provides a whole range of methods, many which I have not listed.
In my instance, I needed to grab LocalHost
along with the Port Number
, so this is what I did:
var Uri uri = Context.Request.Url;
var host = uri.Scheme + Uri.SchemeDelimiter + uri.Host + ":" + uri.Port;
Which successfully grabbed: http://localhost:12345
It returns a string because 0.1, and powers thereof (which are used to display decimal fractions), are not representable (at least not with full accuracy) in binary floating-point systems.
For example, 0.1 is really 0.1000000000000000055511151231257827021181583404541015625, and 0.01 is really 0.01000000000000000020816681711721685132943093776702880859375. (Thanks to BigDecimal
for proving my point. :-P)
Therefore (absent a decimal floating point or rational number type), outputting it as a string is the only way to get it trimmed to exactly the precision required for display.
This counts the rows of the inner query:
select count(*) from (
select count(SID)
from Test
where Date = '2012-12-10'
group by SID
) t
However, in this case the effect of that is the same as this:
select count(distinct SID) from Test where Date = '2012-12-10'
You may use the following method to remove last n
character -
public String removeLast(String s, int n) {
if (null != s && !s.isEmpty()) {
s = s.substring(0, s.length()-n);
}
return s;
}
There's probably a another way or better. But this is how I do this in Spring Boot.
My property file contains the following lines. "," is the delimiter in each line.
mml.pots=STDEP:DETY=LI3;,STDEP:DETY=LIMA;
mml.isdn.grunntengingar=STDEP:DETY=LIBAE;,STDEP:DETY=LIBAMA;
mml.isdn.stofntengingar=STDEP:DETY=LIPRAE;,STDEP:DETY=LIPRAM;,STDEP:DETY=LIPRAGS;,STDEP:DETY=LIPRVGS;
My server config
@Configuration
public class ServerConfig {
@Inject
private Environment env;
@Bean
public MMLProperties mmlProperties() {
MMLProperties properties = new MMLProperties();
properties.setMmmlPots(env.getProperty("mml.pots"));
properties.setMmmlPots(env.getProperty("mml.isdn.grunntengingar"));
properties.setMmmlPots(env.getProperty("mml.isdn.stofntengingar"));
return properties;
}
}
MMLProperties class.
public class MMLProperties {
private String mmlPots;
private String mmlIsdnGrunntengingar;
private String mmlIsdnStofntengingar;
public MMLProperties() {
super();
}
public void setMmmlPots(String mmlPots) {
this.mmlPots = mmlPots;
}
public void setMmlIsdnGrunntengingar(String mmlIsdnGrunntengingar) {
this.mmlIsdnGrunntengingar = mmlIsdnGrunntengingar;
}
public void setMmlIsdnStofntengingar(String mmlIsdnStofntengingar) {
this.mmlIsdnStofntengingar = mmlIsdnStofntengingar;
}
// These three public getXXX functions then take care of spliting the properties into List
public List<String> getMmmlCommandForPotsAsList() {
return getPropertieAsList(mmlPots);
}
public List<String> getMmlCommandsForIsdnGrunntengingarAsList() {
return getPropertieAsList(mmlIsdnGrunntengingar);
}
public List<String> getMmlCommandsForIsdnStofntengingarAsList() {
return getPropertieAsList(mmlIsdnStofntengingar);
}
private List<String> getPropertieAsList(String propertie) {
return ((propertie != null) || (propertie.length() > 0))
? Arrays.asList(propertie.split("\\s*,\\s*"))
: Collections.emptyList();
}
}
Then in my Runner class I Autowire MMLProperties
@Component
public class Runner implements CommandLineRunner {
@Autowired
MMLProperties mmlProperties;
@Override
public void run(String... arg0) throws Exception {
// Now I can call my getXXX function to retrieve the properties as List
for (String command : mmlProperties.getMmmlCommandForPotsAsList()) {
System.out.println(command);
}
}
}
Hope this helps
jQuery UI draggable and droppable are the two plugins I would use to achieve this effect. As for the insertion marker, I would investigate modifying the div
(or container) element that was about to have content dropped into it. It should be possible to modify the border in some way or add a JavaScript/jQuery listener that listens for the hover (element about to be dropped) event and modifies the border or adds an image of the insertion marker in the right place.
You can do it like this:
declare @results varchar(500)
select @results = coalesce(@results + ',', '') + convert(varchar(12),col)
from t
order by col
select @results as results
| RESULTS |
-----------
| 1,3,5,9 |
You mention you are using Pandas (in your title). If so, there is no need to use an external library, you can just use to_datetime
>>> pandas.to_datetime('today').normalize()
Timestamp('2015-10-14 00:00:00')
This will always return today's date at midnight, irrespective of the actual time, and can be directly used in pandas to do comparisons etc. Pandas always includes 00:00:00 in its datetimes.
Replacing today
with now
would give you the date in UTC instead of local time; note that in neither case is the tzinfo (timezone) added.
In pandas versions prior to 0.23.x, normalize
may not have been necessary to remove the non-midnight timestamp.
This can be done very simple, you were pretty close already
SELECT distinct id, DENSE_RANK() OVER (ORDER BY id) AS RowNum
FROM table
WHERE fid = 64
I posted the exact situation on a different thread. Re-post.
Excuse me, This is not an answer to the question posted above.
But brings an interesting topic --- WHEN to use AJAX and when NOT to use AJAX. In this case it's good not to use AJAX.
Let's take a simple example of login and password. If the login and/or password does not match it WOULD be nice to use AJAX to report back a simple message saying "Login Incorrect". But if the login and password IS correct, why would I have to callback an AJAX function to redirect to the user page?
In a case like, this I think it would be just nice to use a simple Form SUBMIT. And if the login fails, redirect to Relogin.php which looks same as the Login.php with a GET message in the url like Relogin.php?error=InvalidLogin... something like that...
Just my 2 cents. :)

All good answers. To put it in simple language [BCNF] No partial key can depend on a key.
i.e No partial subset ( i.e any non trivial subset except the full set ) of a candidate key can be functionally dependent on some candidate key.
I'll explain the main use cases of implicits below, but for more detail see the relevant chapter of Programming in Scala.
Implicit parameters
The final parameter list on a method can be marked implicit
, which means the values will be taken from the context in which they are called. If there is no implicit value of the right type in scope, it will not compile. Since the implicit value must resolve to a single value and to avoid clashes, it's a good idea to make the type specific to its purpose, e.g. don't require your methods to find an implicit Int
!
example:
// probably in a library
class Prefixer(val prefix: String)
def addPrefix(s: String)(implicit p: Prefixer) = p.prefix + s
// then probably in your application
implicit val myImplicitPrefixer = new Prefixer("***")
addPrefix("abc") // returns "***abc"
Implicit conversions
When the compiler finds an expression of the wrong type for the context, it will look for an implicit Function
value of a type that will allow it to typecheck. So if an A
is required and it finds a B
, it will look for an implicit value of type B => A
in scope (it also checks some other places like in the B
and A
companion objects, if they exist). Since def
s can be "eta-expanded" into Function
objects, an implicit def xyz(arg: B): A
will do as well.
So the difference between your methods is that the one marked implicit
will be inserted for you by the compiler when a Double
is found but an Int
is required.
implicit def doubleToInt(d: Double) = d.toInt
val x: Int = 42.0
will work the same as
def doubleToInt(d: Double) = d.toInt
val x: Int = doubleToInt(42.0)
In the second we've inserted the conversion manually; in the first the compiler did the same automatically. The conversion is required because of the type annotation on the left hand side.
Regarding your first snippet from Play:
Actions are explained on this page from the Play documentation (see also API docs). You are using
apply(block: (Request[AnyContent]) ? Result): Action[AnyContent]
on the Action
object (which is the companion to the trait of the same name).
So we need to supply a Function as the argument, which can be written as a literal in the form
request => ...
In a function literal, the part before the =>
is a value declaration, and can be marked implicit
if you want, just like in any other val
declaration. Here, request
doesn't have to be marked implicit
for this to type check, but by doing so it will be available as an implicit value for any methods that might need it within the function (and of course, it can be used explicitly as well). In this particular case, this has been done because the bindFromRequest
method on the Form class requires an implicit Request
argument.
In addition to the answer, you can't directly use output redirection operators in the set part of for
loop (e.g. if you wanna hide stderror output from a user and provide a nicer error message). Instead, you have to escape them with a caret character (^
):
for /f %%O in ('some-erroring-command 2^> nul') do (echo %%O)
Reference: Redirect output of command in for loop of batch script
Note that I prefer the code to be short.
List<ListItem> selected = CBLGold.Items.Cast<ListItem>()
.Where(li => li.Selected)
.ToList();
or with a simple foreach
:
List<ListItem> selected = new List<ListItem>();
foreach (ListItem item in CBLGold.Items)
if (item.Selected) selected.Add(item);
If you just want the ListItem.Value
:
List<string> selectedValues = CBLGold.Items.Cast<ListItem>()
.Where(li => li.Selected)
.Select(li => li.Value)
.ToList();
The simple solution is:
1.keep the image file and HTML file in the same folder.
2.code: <img src="Desert.png">
// your image name.
3.keep the folder in D drive.
Keeping the folder on the desktop(which is c drive) you can face the issue of permission.
I'm assuming you have a typo in your get statement and that it should be test1.get(key). If so, I'm not sure why it is not returning an ArrayList unless you are not putting in the correct type in the map in the first place.
This should work:
// populate the map
Map<String, List<String>> test1 = new LinkedHashMap<String, List<String>>();
test1.put("key1", new ArrayList<String>());
test1.put("key2", new ArrayList<String>());
// loop over the set using an entry set
for( Map.Entry<String,List<String>> entry : test1.entrySet()){
String key = entry.getKey();
List<String>value = entry.getValue();
// ...
}
or you can use
// second alternative - loop over the keys and get the value per key
for( String key : test1.keySet() ){
List<String>value = test1.get(key);
// ...
}
You should use the interface names when declaring your vars (and in your generic params) unless you have a very specific reason why you are defining using the implementation.
You can find the log within you Magento root directory under
var/log
there are two types of log files system.log and exception.log
you need to give the correct permission to var folder, then enable logging from your Magento admin by going to
System > Configuration> Developer > Log Settings > Enable = Yes
system.log is used for general debugging and catches almost all log entries from Magento, including warning, debug and errors messages from both native and custom modules.
exception.log is reserved for exceptions only, for example when you are using try-catch statement.
To output to either the default system.log or the exception.log see the following code examples:
Mage::log('My log entry');
Mage::log('My log message: '.$myVariable);
Mage::log($myArray);
Mage::log($myObject);
Mage::logException($e);
You can create your own log file for more debugging
Mage::log('My log entry', null, 'mylogfile.log');
There are plans for adding mix-ins soon, I believe.
But until then, go with the accepted answer. You can abstract that out a bit to make an "extendable" class:
class Extendable{
private $extender=array();
public function addExtender(Extender $obj){
$this->extenders[] = $obj;
$obj->setExtendee($this);
}
public function __call($name, $params){
foreach($this->extenders as $extender){
//do reflection to see if extender has this method with this argument count
if (method_exists($extender, $name)){
return call_user_func_array(array($extender, $name), $params);
}
}
}
}
$foo = new Extendable();
$foo->addExtender(new OtherClass());
$foo->other_class_method();
Note that in this model "OtherClass" gets to 'know' about $foo. OtherClass needs to have a public function called "setExtendee" to set up this relationship. Then, if it's methods are invoked from $foo, it can access $foo internally. It will not, however, get access to any private/protected methods/variables like a real extended class would.
This is what worked for me:
$.get({
method: 'GET',
url: 'api.php',
headers: {
'Content-Type': 'application/json',
},
// query parameters go under "data" as an Object
data: {
client: 'mikescafe'
}
});
will make a REST/AJAX call - > GET http://localhost:3000/api.php?client=mikescafe
Good Luck.
There is another way of using Uri
and we can achieve the same goal
http://api.example.org/data/2.5/forecast/daily?q=94043&mode=json&units=metric&cnt=7
To build the Uri you can use this:
final String FORECAST_BASE_URL =
"http://api.example.org/data/2.5/forecast/daily?";
final String QUERY_PARAM = "q";
final String FORMAT_PARAM = "mode";
final String UNITS_PARAM = "units";
final String DAYS_PARAM = "cnt";
You can declare all this the above way or even inside the Uri.parse()
and appendQueryParameter()
Uri builtUri = Uri.parse(FORECAST_BASE_URL)
.buildUpon()
.appendQueryParameter(QUERY_PARAM, params[0])
.appendQueryParameter(FORMAT_PARAM, "json")
.appendQueryParameter(UNITS_PARAM, "metric")
.appendQueryParameter(DAYS_PARAM, Integer.toString(7))
.build();
At last
URL url = new URL(builtUri.toString());
A non-jQuery way to get the available screen dimension. window.screen.width/height
has already been put up, but for responsive webdesign and completeness sake I think its worth to mention those attributes:
alert(window.screen.availWidth);
alert(window.screen.availHeight);
http://www.quirksmode.org/dom/w3c_cssom.html#t10 :
availWidth and availHeight - The available width and height on the screen (excluding OS taskbars and such).
There is no need to install Anaconda again. Conda, the package manager for Anaconda, fully supports separated environments. The easiest way to create an environment for Python 2.7 is to do
conda create -n python2 python=2.7 anaconda
This will create an environment named python2
that contains the Python 2.7 version of Anaconda. You can activate this environment with
source activate python2
This will put that environment (typically ~/anaconda/envs/python2
) in front in your PATH
, so that when you type python
at the terminal it will load the Python from that environment.
If you don't want all of Anaconda, you can replace anaconda
in the command above with whatever packages you want. You can use conda
to install packages in that environment later, either by using the -n python2
flag to conda
, or by activating the environment.
You can also use Apache's ExceptionUtils.
Example:
import org.apache.commons.lang.exception.ExceptionUtils;
import org.apache.log4j.Logger;
public class Test {
static Logger logger = Logger.getLogger(Test.class);
public static void main(String[] args) {
try{
String[] avengers = null;
System.out.println("Size: "+avengers.length);
} catch (NullPointerException e){
logger.info(ExceptionUtils.getFullStackTrace(e));
}
}
}
Console output:
java.lang.NullPointerException
at com.aimlessfist.avengers.ironman.Test.main(Test.java:11)
Try the following:
^((ht|f)tp(s?)\:\/\/|~/|/)?([\w]+:\w+@)?([a-zA-Z]{1}([\w\-]+\.)+([\w]{2,5}))(:[\d]{1,5})?((/?\w+/)+|/?)(\w+\.[\w]{3,4})?((\?\w+=\w+)?(&\w+=\w+)*)?
It supports HTTP / FTP, subdomains, folders, files etc.
I found it from a quick google search:
http://geekswithblogs.net/casualjim/archive/2005/12/01/61722.aspx
First, open a terminal session and run:
cd /usr/local/
git status
to see if Homebrew is clean.
If it's dirty, run:
git reset --hard && git clean -df
then
brew doctor
brew update
If it's still broken, try this in your session:
sudo rm /System/Library/Frameworks/Ruby.framework/Versions/Current
sudo ln -s /System/Library/Frameworks/Ruby.framework/Versions/1.8 /System/Library/Frameworks/Ruby.framework/Versions/Current
This will force Homebrew to use Ruby 1.8 from the system's installation.

OP here (I am answering this question after two years, the post made by Daniel Cerecedo was not bad at a time, but the web services are developing very fast)
After three years of full-time software development (with focus also on software architecture, project management and microservice architecture) I definitely choose the second way (but with one general endpoint) as the best one.
If you have a special endpoint for images, it gives you much more power over handling those images.
We have the same REST API (Node.js) for both - mobile apps (iOS/android) and frontend (using React). This is 2017, therefore you don't want to store images locally, you want to upload them to some cloud storage (Google cloud, s3, cloudinary, ...), therefore you want some general handling over them.
Our typical flow is, that as soon as you select an image, it starts uploading on background (usually POST on /images endpoint), returning you the ID after uploading. This is really user-friendly, because user choose an image and then typically proceed with some other fields (i.e. address, name, ...), therefore when he hits "send" button, the image is usually already uploaded. He does not wait and watching the screen saying "uploading...".
The same goes for getting images. Especially thanks to mobile phones and limited mobile data, you don't want to send original images, you want to send resized images, so they do not take that much bandwidth (and to make your mobile apps faster, you often don't want to resize it at all, you want the image that fits perfectly into your view). For this reason, good apps are using something like cloudinary (or we do have our own image server for resizing).
Also, if the data are not private, then you send back to app/frontend just URL and it downloads it from cloud storage directly, which is huge saving of bandwidth and processing time for your server. In our bigger apps there are a lot of terabytes downloaded every month, you don't want to handle that directly on each of your REST API server, which is focused on CRUD operation. You want to handle that at one place (our Imageserver, which have caching etc.) or let cloud services handle all of it.
Cons : The only "cons" which you should think of is "not assigned images". User select images and continue with filling other fields, but then he says "nah" and turn off the app or tab, but meanwhile you successfully uploaded the image. This means you have uploaded an image which is not assigned anywhere.
There are several ways of handling this. The most easiest one is "I don't care", which is a relevant one, if this is not happening very often or you even have desire to store every image user send you (for any reason) and you don't want any deletion.
Another one is easy too - you have CRON and i.e. every week and you delete all unassigned images older than one week.
This indicates the linux has delivered a SIGTERM
to your process. This is usually at the request of some other process (via kill()
) but could also be sent by your process to itself (using raise()
). This signal requests an orderly shutdown of your process.
If you need a quick cheatsheet of signal numbers, open a bash shell and:
$ kill -l
1) SIGHUP 2) SIGINT 3) SIGQUIT 4) SIGILL
5) SIGTRAP 6) SIGABRT 7) SIGBUS 8) SIGFPE
9) SIGKILL 10) SIGUSR1 11) SIGSEGV 12) SIGUSR2

You can determine the sender by using an appropriate signal handler like:
#include <signal.h>
#include <stdio.h>
#include <stdlib.h>
void sigterm_handler(int signal, siginfo_t *info, void *_unused)
{
fprintf(stderr, "Received SIGTERM from process with pid = %u\n",
info->si_pid);
exit(0);
}
int main (void)
{
struct sigaction action = {
.sa_handler = NULL,
.sa_sigaction = sigterm_handler,
.sa_mask = 0,
.sa_flags = SA_SIGINFO,
.sa_restorer = NULL
};
sigaction(SIGTERM, &action, NULL);
sleep(60);
return 0;
}
Notice that the signal handler also includes a call to exit()
. It's also possible for your program to continue to execute by ignoring the signal, but this isn't recommended in general (if it's a user doing it there's a good chance it will be followed by a SIGKILL if your process doesn't exit, and you lost your opportunity to do any cleanup then).

It depends on what you mean by "dropped". For TCP sockets, if the other end closes the connection either through close() or the process terminating, you'll find out by reading an end of file, or getting a read error, usually the errno being set to whatever 'connection reset by peer' is by your operating system. For python, you'll read a zero length string, or a socket.error will be thrown when you try to read or write from the socket.
Take a look at my implementation. It's safe from null lists.
IList<string> all= new List<string>();
if (letterForm.SecretaryPhone!=null)// first list may be null
all=all.Concat(letterForm.SecretaryPhone).ToList();
if (letterForm.EmployeePhone != null)// second list may be null
all= all.Concat(letterForm.EmployeePhone).ToList();
if (letterForm.DepartmentManagerName != null) // this is not list (its just string variable) so wrap it inside list then concat it
all = all.Concat(new []{letterForm.DepartmentManagerPhone}).ToList();
Sometimes, this error pops up because of the kernel has reached its limit. Try to restart the kernel redo the necessary steps.
Try the following code:
first = [1, 2, 3, 4]
second = [2, 3, 4, 5]
third = map(sum, zip(first, second))
In order to achieve validation when both inputs change, I use the following code (which was a combination of all others other answers):
angular.module('app.directives')
.directive('passwordVerify', [function () {
return {
require: '?ngModel',
restrict: 'A',
scope: {
origin: '=passwordVerify'
},
link: function (scope, element, attrs, ctrl) {
if(!ctrl) {
return;
}
function validate(value) {
ctrl.$setValidity('passwordMatch', scope.origin === value);
return value;
}
ctrl.$parsers.unshift(validate);
scope.$watch('origin', function(value) {
validate(ctrl.$viewValue);
});
}
};
}]);
int
to Hex :
Integer.toHexString(intValue);
Hex to int
:
Integer.valueOf(hexString, 16).intValue();
You may also want to use long
instead of int
(if the value does not fit the int
bounds):
Hex to long
:
Long.valueOf(hexString, 16).longValue()
long
to Hex
Long.toHexString(longValue)
FileUtils from apache commons is a pretty good way to achieve this in a single line.
FileOutputStream s = FileUtils.openOutputStream(new File("/home/nikhil/somedir/file.txt"))
This will create parent folders if do not exist and create a file if not exists and throw a exception if file object is a directory or cannot be written to. This is equivalent to:
File file = new File("/home/nikhil/somedir/file.txt");
file.getParentFile().mkdirs(); // Will create parent directories if not exists
file.createNewFile();
FileOutputStream s = new FileOutputStream(file,false);
All the above operations will throw an exception if the current user is not permitted to do the operation.
C90 does not support the boolean data type.
C99 does include it with this include:
#include <stdbool.h>
How about this?
fscanf(file,"%d %d %d %d %d %d %d",&line1_1,&line1_2, &line1_3, &line2_1, &line2_2, &line3_1, &line3_2);
In this case spaces in fscanf
match multiple occurrences of any whitespace until the next token in found.

I came up with a solution that I call “BatchImageDownloader” that has served well. Here’s a quick summary of how it is used:
Keep a global HashMap (ideally in your Application object) that serves as a cache of drawable objects
In the getView() method of your List Adapter, use the drawable from the cache for populating the ImageView in your list item.
Create an instance of BatchImageDownloader, passing in your ListView Adapter
Call addUrl() for each image that needs to be fetched/displayed
When done, call execute(). This fires an AsyncTask that fetches all images, and as each image is fetched and added to the cache, it refreshes your ListView (by calling notifyDataSetChanged())
The approach has the following advantages:
Here is the source code of BatchImageDownloader:
package com.mobrite.androidutils;
import java.io.IOException;
import java.io.InputStream;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import org.apache.http.HttpResponse;
import org.apache.http.client.ClientProtocolException;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import android.graphics.drawable.Drawable;
import android.os.AsyncTask;
import android.widget.BaseAdapter;
public class BatchImageDownloader extends AsyncTask<Void, Void, Void> {
List<String> imgUrls = new ArrayList<String>();
BaseAdapter adapter;
HashMap<String, Drawable> imageCache;
public BatchImageDownloader(BaseAdapter adapter,
HashMap<String, Drawable> imageCache) {
this.adapter = adapter;
this.imageCache = imageCache;
}
public void addUrl(String url) {
imgUrls.add(url);
}
@Override
protected Void doInBackground(Void... params) {
for (String url : imgUrls) {
if (!imageCache.containsKey(url)) {
Drawable bm = downloadImage(url);
if (null != bm) {
imageCache.put(url, bm);
publishProgress();
}
}
}
return null;
}
@Override
protected void onProgressUpdate(Void... values) {
adapter.notifyDataSetChanged();
}
@Override
protected void onPostExecute(Void result) {
adapter.notifyDataSetChanged();
}
public Drawable downloadImage(String url) {
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet request = new HttpGet(url);
try {
HttpResponse response = httpClient.execute(request);
InputStream stream = response.getEntity().getContent();
Drawable drawable = Drawable.createFromStream(stream, "src");
return drawable;
} catch (ClientProtocolException e) {
e.printStackTrace();
return null;
} catch (IllegalStateException e) {
e.printStackTrace();
return null;
} catch (IOException e) {
e.printStackTrace();
return null;
}
}
}
This is because the CHARINDEX-1 is returning a -ive value if the look-up for " " (space) is 0. The simplest solution would be to avoid '-ve' by adding
ABS(CHARINDEX(' ', PostCode ) -1))
which will return only +ive values for your length even if CHARINDEX(' ', PostCode ) -1)
is a -ve value. Correct me if I'm wrong!

For completing the answers, Spring MVC uses viewResolver(for example, as axtavt metionned, InternalResourceViewResolver) to get the specific view. Therefore the first step is making sure that a viewResolver is configured.
Secondly, you should pay attention to the url of redirection(redirect or forward). A url starting with "/" means that it's a url absolute in the application. As Jigar says,
return "redirect:/index.html";
should work. If your view locates in the root of the application, Spring can find it. If a url without a "/", such as that in your question, it means a url relative. It explains why it worked before and don't work now. If your page calling "redirect" locates in the root by chance, it works. If not, Spring can't find the view and it doesn't work.
Here is the source code of the method of RedirectView of Spring
protected void renderMergedOutputModel(
Map<String, Object> model, HttpServletRequest request, HttpServletResponse response)
throws IOException {
// Prepare target URL.
StringBuilder targetUrl = new StringBuilder();
if (this.contextRelative && getUrl().startsWith("/")) {
// Do not apply context path to relative URLs.
targetUrl.append(request.getContextPath());
}
targetUrl.append(getUrl());
// ...
sendRedirect(request, response, targetUrl.toString(), this.http10Compatible);
}
As drew_w said, you can find a good example here.

Running in a Docker container introduced a whole slew of additional problems for connecting so hopefully this helps someone. I ended up needed to add the following options which I'll explain below:
-Dcom.sun.management.jmxremote=true
-Dcom.sun.management.jmxremote.local.only=false
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.ssl=false
-Djava.rmi.server.hostname=${DOCKER_HOST_IP}
-Dcom.sun.management.jmxremote.port=9999
-Dcom.sun.management.jmxremote.rmi.port=9998
DOCKER_HOST_IP
Unlike using jconsole locally, you have to advertise a different IP than you'll probably see from within the container. You'll need to replace ${DOCKER_HOST_IP}
with the externally resolvable IP (DNS Name) of your Docker host.
JMX Remote & RMI Ports
It looks like JMX also requires access to a remote management interface (jstat) that uses a different port to transfer some data when arbitrating the connection. I didn't see anywhere immediately obvious in jconsole
to set this value. In the linked article the process was:
jconsole
with logging enabledjconsole
attempted to useiptables
/firewall
rules as necessary to allow that port to connectWhile that works, it's certainly not an automatable solution. I opted for an upgrade from jconsole to VisualVM since it let's you to explicitly specify the port on which jstatd
is running. In VisualVM, add a New Remote Host and update it with values that correlate to the ones specified above:
Then right-click the new Remote Host Connection and Add JMX Connection...
Don't forget to check the checkbox for Do not require SSL connection
. Hopefully, that should allow you to connect.
Regarding the question 'can R help me find the best fitting model', there is probably a function to do this, assuming you can state the set of models to test, but this would be a good first approach for the set of n-1 degree polynomials:
polyfit <- function(i) x <- AIC(lm(y~poly(x,i)))
as.integer(optimize(polyfit,interval = c(1,length(x)-1))$minimum)
Notes
The validity of this approach will depend on your objectives, the assumptions of optimize()
and AIC()
and if AIC is the criterion that you want to use,
polyfit()
may not have a single minimum. check this with something like:
for (i in 2:length(x)-1) print(polyfit(i))
I used the as.integer()
function because it is not clear to me how I would interpret a non-integer polynomial.
for testing an arbitrary set of mathematical equations, consider the 'Eureqa' program reviewed by Andrew Gelman here
Update
Also see the stepAIC
function (in the MASS package) to automate model selection.
Run this SQL:
select * from v$version;

OR
tr td:first-child {padding-left:0px;}
td {padding:10px 0px 10px 50px;}
The direct answer to this question is:
if(rows.Any()) //prevent IndexOutOfRangeException for empty list
{
rows.RemoveAt(rows.Count - 1);
}
However... in the specific case of this question, it makes more sense not to add the row in the first place:
Row row = new Row();
//...
if (!row.cell[0].Equals("Something"))
{
rows.Add(row);
}
TBH, I'd go a step further by testing "Something"
against user.""
, and not even instantiating a Row
unless the condition is satisfied, but seeing as user.""
won't compile, I'll leave that as an exercise for the reader.
Whenever you are in the following situation:
a = []
for i in range(5):
a.append(i)
and you want something similar in numpy, several previous answers have pointed out ways to do it, but as @katrielalex pointed out these methods are not efficient. The efficient way to do this is to build a long list and then reshape it the way you want after you have a long list. For example, let's say I am reading some lines from a file and each row has a list of numbers and I want to build a numpy array of shape (number of lines read, length of vector in each row). Here is how I would do it more efficiently:
long_list = []
counter = 0
with open('filename', 'r') as f:
for row in f:
row_list = row.split()
long_list.extend(row_list)
counter++
# now we have a long list and we are ready to reshape
result = np.array(long_list).reshape(counter, len(row_list)) # desired numpy array
The Spring Framework has a class which allows to recursively search through the classpath:

loads of reading documentation on how to round numbers, many experts suggest writing your own rounding routines, as the 'canned' version provided with your language may not be precise enough, or contain errors. i imagine, however, they're talking many decimal places not just one, two, or three. with that in mind, here is my solution (although not EXACTLY as requested as my needs are to display dollars - the process is not much different, though).
sub asDollars($) {
my ($cost) = @_;
my $rv = 0;
my $negative = 0;
if ($cost =~ /^-/) {
$negative = 1;
$cost =~ s/^-//;
}
my @cost = split(/\./, $cost);
# let's get the first 3 digits of $cost[1]
my ($digit1, $digit2, $digit3) = split("", $cost[1]);
# now, is $digit3 >= 5?
# if yes, plus one to $digit2.
# is $digit2 > 9 now?
# if yes, $digit2 = 0, $digit1++
# is $digit1 > 9 now??
# if yes, $digit1 = 0, $cost[0]++
if ($digit3 >= 5) {
$digit3 = 0;
$digit2++;
if ($digit2 > 9) {
$digit2 = 0;
$digit1++;
if ($digit1 > 9) {
$digit1 = 0;
$cost[0]++;
}
}
}
$cost[1] = $digit1 . $digit2;
if ($digit1 ne "0" and $cost[1] < 10) { $cost[1] .= "0"; }
# and pretty up the left of decimal
if ($cost[0] > 999) { $cost[0] = commafied($cost[0]); }
$rv = join(".", @cost);
if ($negative) { $rv = "-" . $rv; }
return $rv;
}
sub commafied($) {
#*
# to insert commas before every 3rd number (from the right)
# positive or negative numbers
#*
my ($num) = @_; # the number to insert commas into!
my $negative = 0;
if ($num =~ /^-/) {
$negative = 1;
$num =~ s/^-//;
}
$num =~ s/^(0)*//; # strip LEADING zeros from given number!
$num =~ s/0/-/g; # convert zeros to dashes because ... computers!
if ($num) {
my @digits = reverse split("", $num);
$num = "";
for (my $i = 0; $i < @digits; $i += 3) {
$num .= $digits[$i];
if ($digits[$i+1]) { $num .= $digits[$i+1]; }
if ($digits[$i+2]) { $num .= $digits[$i+2]; }
if ($i < (@digits - 3)) { $num .= ","; }
if ($i >= @digits) { last; }
}
#$num =~ s/,$//;
$num = join("", reverse split("", $num));
$num =~ s/-/0/g;
}
if ($negative) { $num = "-" . $num; }
return $num; # a number with commas added
#usage: my $prettyNum = commafied(1234567890);

Excel has no way of gathering that attribute with it's built-in functions. If you're willing to use some VB, all your color-related questions are answered here:
http://www.cpearson.com/excel/colors.aspx
Example form the site:
The SumColor function is a color-based analog of both the SUM and SUMIF function. It allows you to specify separate ranges for the range whose color indexes are to be examined and the range of cells whose values are to be summed. If these two ranges are the same, the function sums the cells whose color matches the specified value. For example, the following formula sums the values in B11:B17 whose fill color is red.
=SUMCOLOR(B11:B17,B11:B17,3,FALSE)

2. Object o is a prestationEco object. Not a String.
mbaird's answer works fine. Just be aware that there seems to be a bug in Android (2.1 at least), that if you set any individual corner's radius to 0, it forces all the corners to 0 (at least that's the case with "dp" units; I didn't try it with any other units).
I needed a shape where the top corners were rounded and the bottom corners were square. I got achieved this by setting the corners I wanted to be square to a value slightly larger than 0: 0.1dp. This still renders as square corners, but it doesn't force the other corners to be 0 radius.
The error possibly comes because of the different structure of the code that you are committing and that present on GitHub. It creates conflicts which can be solved by
git pull
Merge conflicts resolving:
git push
If you confirm that your new code is all fine you can use:
git push -f origin master
Where -f
stands for "force commit".
You can read about it here.

I had this problem when I did a SharePoint 2010 to 2013 migration. I suspected that because the database server is on the other side of a firewall which does not route IP6 that it was trying then to use IP6 and failing when connecting to the database.
I think the issue is now solved. The errors seem to have stopped. What I did was I simply disabled IP6 (by unchecking it) for the network adapter on the SharePoint Servers.
May be this will help some one. I have my proxy setup in python script but keep getting the error mentioned in the question.

auth = req.HTTPBasicAuthHandler()
opener = req.build_opener(proxy, auth, req.HTTPHandler)
req.install_opener(opener)
If you are using corporate laptop and if you did not connect to Direct Access or office VPN then the above block will throw error. All you need to do is to connect to your org VPN and then execute your python script.

This worked out for me.
Use "php -l <filename>" (that's an 'L') from the command line to output the syntax error that could be causing PHP to throw the status 500 error. It'll output something like:
PHP Parse error: syntax error, unexpected '}' in <filename> on line 18
Adding dependencies didn't fix the issue at my end.
The issue was happening at my end because of "additional" fields that are part of the "@Entity" class and don't exist in the database.
I removed the additional fields from the @Entity class and it worked.

act as componentDidMount, componentDidUpdate, so after updating state it will work
Simple and dirty way using $rootScope
:
<html ng-app="project">
<head>
<title ng-bind="title">Placeholder title</title>
In your controllers, when you have the data necessary to create the title, do:
$rootScope.title = 'Page X'
Move the config files from src/main/java
to src/main/resources
.
This command will redirect the output to a text file of your choice:
$hive -e "select * from table where id > 10" > ~/sample_output.txt
There are a few ways to rerender your component:
The simplest solution is to use forceUpdate() method:
this.forceUpdate()
One more solution is to create not used key in the state(nonUsedKey) and call setState function with update of this nonUsedKey:
this.setState({ nonUsedKey: Date.now() } );
Or rewrite all current state:
this.setState(this.state);
Props changing also provides component rerender.

From a Terminal prompt:
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
The command brew install wget
is an example of how to use Homebrew to install another application (in this case, wget
) after brew is already installed.

Above command to install the Brew is migrated to:

Specifically if someone is facing problem in Chrome
:
What you need to do to fix this is to use the onSubmit
tag in the <form>
element to set the submit button disabled
. This will allow Chrome to disable the button immediately after it is pressed and the form submission will still go ahead...
<form name ="myform" method="POST" action="dosomething.php" onSubmit="document.getElementById('submit').disabled=true;">
<input type="submit" name="submit" value="Submit" id="submit">
</form>
This happens when you index a row/column with a number that is larger than the dimensions of your dataframe
. For instance, getting the eleventh column when you have only three.
import pandas as pd
df = pd.DataFrame({'Name': ['Mark', 'Laura', 'Adam', 'Roger', 'Anna'],
'City': ['Lisbon', 'Montreal', 'Lisbon', 'Berlin', 'Glasgow'],
'Car': ['Tesla', 'Audi', 'Porsche', 'Ford', 'Honda']})
You have 5 rows and three columns:
Name City Car
0 Mark Lisbon Tesla
1 Laura Montreal Audi
2 Adam Lisbon Porsche
3 Roger Berlin Ford
4 Anna Glasgow Honda
Let's try to index the eleventh column (it doesn't exist):
df.iloc[:, 10] # there is obviously no 11th column
IndexError: single positional indexer is out-of-bounds
If you are a beginner with Python, remember that df.iloc[:, 10]
would refer to the eleventh column.

why not just pass an data an object with your key/value pairs then you don't have to worry about encoding

I want to create a 2D array that each cell is an ArrayList!
If you want to create a 2D array of ArrayList
.Then you can do this :
ArrayList[][] table = new ArrayList[10][10];
table[0][0] = new ArrayList(); // add another ArrayList object to [0,0]
table[0][0].add(); // add object to that ArrayList
You are getting this error because the value cannot be found in the range. String or integer doesn't matter. Best thing to do in my experience is to do a check first to see if the value exists.
I used CountIf below, but there is lots of different ways to check existence of a value in a range.
Public Sub test()
Dim rng As Range
Dim aNumber As Long
aNumber = 666
Set rng = Sheet5.Range("B16:B615")
If Application.WorksheetFunction.CountIf(rng, aNumber) > 0 Then
rowNum = Application.WorksheetFunction.Match(aNumber, rng, 0)
Else
MsgBox aNumber & " does not exist in range " & rng.Address
End If
End Sub
ALTERNATIVE WAY
Public Sub test()
Dim rng As Range
Dim aNumber As Variant
Dim rowNum As Long
aNumber = "2gg"
Set rng = Sheet5.Range("B1:B20")
If Not IsError(Application.Match(aNumber, rng, 0)) Then
rowNum = Application.Match(aNumber, rng, 0)
MsgBox rowNum
Else
MsgBox "error"
End If
End Sub
OR
Public Sub test()
Dim rng As Range
Dim aNumber As Variant
Dim rowNum As Variant
aNumber = "2gg"
Set rng = Sheet5.Range("B1:B20")
rowNum = Application.Match(aNumber, rng, 0)
If Not IsError(rowNum) Then
MsgBox rowNum
Else
MsgBox "error"
End If

In my case $(document).ready(function() was missing. Try this.
$(document).ready(function(){
("#table tr").click(function(){
$(this).addClass('selected').siblings().removeClass('selected');
var value=$(this).find('td:first').html();
alert(value);
});
$('.ok').on('click', function(e){
alert($("#table tr.selected td:first").html());
});
});
Added MSSQLSERVER full access to the folder, diskadmin and bulkadmin server roles.
In my c# application, when preparing for the bulk insert command,
string strsql = "BULK INSERT PWCR_Contractor_vw_TEST FROM '" + strFileName + "' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\\n')";
And I get this error - Bulk load data conversion error (type mismatch or invalid character for the specified codepage) for row 1, column 8 (STATUS).
I looked at my logfile and found that the terminator becomes ' ' instead of '\n'. The OLE DB provider "BULK" for linked server "(null)" reported an error. The provider did not give any information about the error:
Cannot fetch a row from OLE DB provider "BULK" for linked server "(null)". Query :BULK INSERT PWCR_Contractor_vw_TEST FROM 'G:\NEWSTAGEWWW\CalAtlasToPWCR\Results\parsedRegistration.csv' WITH (FIELDTERMINATOR = ',', **ROWTERMINATOR = ''**)
So I added extra escape to the rowterminator - string strsql = "BULK INSERT PWCR_Contractor_vw_TEST FROM '" + strFileName + "' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\\n')";
And now it inserts successfully.
Bulk Insert SQL - ---> BULK INSERT PWCR_Contractor_vw_TEST FROM 'G:\\NEWSTAGEWWW\\CalAtlasToPWCR\\Results\\parsedRegistration.csv' WITH (FIELDTERMINATOR = ',', ROWTERMINATOR = '\n')
Bulk Insert to PWCR_Contractor_vw_TEST successful... ---> clsDatase.PerformBulkInsert
Fastest way to do this is using "SELECT INTO" command e.g.
SELECT * INTO #TempTableName
FROM....
This will create a new table, you don't have to create it in advance.
My problem was including minutes in the file name - it looked for appname_debug_0.9.0.1_170214_2216.apk when the generated file was appname_debug_0.9.0.1_170214_2217.apk so the output filename code (nabbed from elsewhere) was clearly being called from two different points in the build.
applicationVariants.all { variant ->
variant.outputs.each { output ->
def project = "appname"
def SEP = "_"
// def flavor = variant.productFlavors[0].name
def buildType = variant.variantData.variantConfiguration.buildType.name
def version = variant.versionName
def date = new Date();
def formattedDate = date.format('yyMMdd_HHmm')
def newApkName = project + SEP + /*flavor + */ SEP + buildType + SEP + version + SEP + formattedDate + ".apk"
output.outputFile = new File(output.outputFile.parent, newApkName)
}
}
This worked for me:
Do
$ git status
And check if you have Unmerged paths
# Unmerged paths:
# (use "git reset HEAD <file>..." to unstage)
# (use "git add <file>..." to mark resolution)
#
# both modified: app/assets/images/logo.png
# both modified: app/models/laundry.rb
Fix them with git add
to each of them and try git stash
again.
git add app/assets/images/logo.png
Note that this problem usually occure for two reasons:
1-Port 80 is busy.
2-Port 443 is busy.
For number one as the others said, you can kill Skype and SQL Serever Reporter from
Windows Task Manager>"Services" Tab>"Services..." Button.
But if it dosen't worked, it's probably because of port 443, so try this one:
If you use VMware, go to
Windows Task Manager>"Services" Tab>"Services..." Button, and find "VMware Workstation Server" service, double click on it and press "Stop" button.
There is no need to stop other VMware's services.
Then again try to run Apache
I know that it is very late to answer the question, but it may help someone like me who spent lots off time to fetch data using hql
So the thing is you just have to write a query
Query query = session.createQuery("from Employee");
it will give you all the data list but to fetch data from this you have to write this line.
List<Employee> fetchedData = query.list();
As simple as it looks.

Using ruby 2.4 you can do the same thing using transform_values
, this feature extracted from rails to ruby.
h = {a: 1, b: 2, c: 3}
h.transform_values { |v| v * 10 }
#=> {a: 10, b: 20, c: 30}
In C#, per MSDN library, we have the "const" keyword that does the work of the "#define" keyword in other languages.
"...when the compiler encounters a constant identifier in C# source code (for example, months), it substitutes the literal value directly into the intermediate language (IL) code that it produces." ( https://msdn.microsoft.com/en-us/library/ms173119.aspx )
Initialize constants at time of declaration since there is no changing them.
public const int cMonths = 12;
You are correct with your observation.
If x == 0.0
, then abs(x) * epsilon
is zero and you're testing whether abs(y) <= 0.0
.
If y == 0.0
then you're testing abs(x) <= abs(x) * epsilon
which means either epsilon >= 1
(it isn't) or x == 0.0
.
So either is_equal(val, 0.0)
or is_equal(0.0, val)
would be pointless, and you could just say val == 0.0
. If you want to only accept exactly +0.0
and -0.0
.
The FAQ's recommendation in this case is of limited utility. There is no "one size fits all" floating-point comparison. You have to think about the semantics of your variables, the acceptable range of values, and the magnitude of error introduced by your computations. Even the FAQ mentions a caveat, saying this function is not usually a problem "when the magnitudes of x and y are significantly larger than epsilon, but your mileage may vary".
Try this to get all the list at first, then your desired element (say the First in your case):
var desiredElementCompoundValueList = new List<YourType>();
dic.Values.ToList().ForEach( elem =>
{
desiredElementCompoundValue.Add(elem.ComponentValue("Dep"));
});
var x = desiredElementCompoundValueList.FirstOrDefault();
To get directly the first element value without a lot of foreach iteration and variable assignment:
var desiredCompoundValue = dic.Values.ToList().Select( elem => elem.CompoundValue("Dep")).FirstOrDefault();
See the difference between the two approaches: in the first one you get the list through a ForEach, then your element. In the second you can get your value in a straight way.
Same result, different computation ;)
Doing this yourself will give you insight into how a WSDL is structured and how it gets your job done. It is a good learning opportunity. This can be done using soapUI, if you only have the URL of the WSDL. (I'm using soapUI 5.2.1) If you actually have the complete WSDL as a file available to you, you don't even need soapUI. The title of the question says "Request & Response XML" while the question body says "Request & Response XML formats" which I interpret as the schema of the request and response. At any rate, the following will give you the schema which you can use on XSD2XML to generate sample XML.
<s:element name="GetWeather">
and ends with </s:element>
.
<?xml version="1.0" encoding="UTF-8"?>
<s:schema xmlns:s="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified">
</s:schema>

Answer without the need for a exterior array or additional function
function permutator (arr) {
var permutations = [];
if (arr.length === 1) {
return [ arr ];
}
for (var i = 0; i < arr.length; i++) {
var subPerms = permutator(arr.slice(0, i).concat(arr.slice(i + 1)));
for (var j = 0; j < subPerms.length; j++) {
subPerms[j].unshift(arr[i]);
permutations.push(subPerms[j]);
}
}
return permutations;
}
If you are using CMS like Drupal or Wordpress - just install jQuery Update module and error no longer persists.
Add second parameter
You need to pass additional parameter to your function:
function parts($site_url, $part) {
$structure = 'http://' . $site_url . 'content/';
echo $structure . $part . '.php';
}
In case of closures
If you'd rather use closures then you can import variable to the current scope (the use
keyword):
$parts = function($part) use ($site_url) {
$structure = 'http://' . $site_url . 'content/';
echo $structure . $part . '.php';
};
global
- a bad practice
This post is frequently read, so something needs to be clarified about global
. Using it is considered a bad practice (refer to this and this).
For the completeness sake here is the solution using global
:
function parts($part) {
global $site_url;
$structure = 'http://' . $site_url . 'content/';
echo($structure . $part . '.php');
}
It works because you have to tell interpreter that you want to use a global variable, now it thinks it's a local variable (within your function).
Suggested reading:
P stands for polynomial time. NP stands for non-deterministic polynomial time.
Definitions:
Polynomial time means that the complexity of the algorithm is O(n^k), where n is the size of your data (e. g. number of elements in a list to be sorted), and k is a constant.
Complexity is time measured in the number of operations it would take, as a function of the number of data items.
Operation is whatever makes sense as a basic operation for a particular task. For sorting, the basic operation is a comparison. For matrix multiplication, the basic operation is multiplication of two numbers.
Now the question is, what does deterministic vs. non-deterministic mean? There is an abstract computational model, an imaginary computer called a Turing machine (TM). This machine has a finite number of states, and an infinite tape, which has discrete cells into which a finite set of symbols can be written and read. At any given time, the TM is in one of its states, and it is looking at a particular cell on the tape. Depending on what it reads from that cell, it can write a new symbol into that cell, move the tape one cell forward or backward, and go into a different state. This is called a state transition. Amazingly enough, by carefully constructing states and transitions, you can design a TM, which is equivalent to any computer program that can be written. This is why it is used as a theoretical model for proving things about what computers can and cannot do.
There are two kinds of TM's that concern us here: deterministic and non-deterministic. A deterministic TM only has one transition from each state for each symbol that it is reading off the tape. A non-deterministic TM may have several such transition, i. e. it is able to check several possibilities simultaneously. This is sort of like spawning multiple threads. The difference is that a non-deterministic TM can spawn as many such "threads" as it wants, while on a real computer only a specific number of threads can be executed at a time (equal to the number of CPUs). In reality, computers are basically deterministic TMs with finite tapes. On the other hand, a non-deterministic TM cannot be physically realized, except maybe with a quantum computer.
It has been proven that any problem that can be solved by a non-deterministic TM can be solved by a deterministic TM. However, it is not clear how much time it will take. The statement P=NP means that if a problem takes polynomial time on a non-deterministic TM, then one can build a deterministic TM which would solve the same problem also in polynomial time. So far nobody has been able to show that it can be done, but nobody has been able to prove that it cannot be done, either.
NP-complete problem means an NP problem X, such that any NP problem Y can be reduced to X by a polynomial reduction. That implies that if anyone ever comes up with a polynomial-time solution to an NP-complete problem, that will also give a polynomial-time solution to any NP problem. Thus that would prove that P=NP. Conversely, if anyone were to prove that P!=NP, then we would be certain that there is no way to solve an NP problem in polynomial time on a conventional computer.
An example of an NP-complete problem is the problem of finding a truth assignment that would make a boolean expression containing n variables true.
For the moment in practice any problem that takes polynomial time on the non-deterministic TM can only be done in exponential time on a deterministic TM or on a conventional computer.
For example, the only way to solve the truth assignment problem is to try 2^n possibilities.
FireBug Lite: http://getfirebug.com/firebuglite
You can also use unlist()
, which is often useful for handling lists:
> mylist <- list(A = c(1:3), B = c(4:6), C = c(7:9))
> mylist
$A
[1] 1 2 3
$B
[1] 4 5 6
$C
[1] 7 8 9
> unlist(mylist)
A1 A2 A3 B1 B2 B3 C1 C2 C3
1 2 3 4 5 6 7 8 9
> length(unlist(mylist))
[1] 9
unlist() is a simple way of executing other functions on lists as well, such as:
> sum(mylist)
Error in sum(mylist) : invalid 'type' (list) of argument
> sum(unlist(mylist))
[1] 45
you can use simply inside your controller:
return response()->download($filePath);
Happy coding :)
You can wrap jQuery calls inside normal JavaScript code. So, for example:
$(document).ready(function() {
if (someCondition && someOtherCondition) {
// Make some jQuery call.
}
});
You can also do it as part of the declaration:
int[] a = new int[] {0, 0, 0, 0};
Just to add to roya's answer. In c# 6.0 you can now use string interpolation:
Console.WriteLine($"{customer[DisplayPos],10}" +
$"{salesFigures[DisplayPos],10}" +
$"{feePayable[DisplayPos],10}" +
$"{seventyPercentValue,10}" +
$"{thirtyPercentValue,10}");
This can actually be one line without all the extra dollars, I just think it makes it a bit easier to read like this.
And you could also use a static import on System.Console, allowing you to do this:
using static System.Console;
WriteLine(/* write stuff */);
public class arrayFloats {
public static void main (String [] args){
float [] Values = new float[3];
float Incre = 0.1f;
int Count = 0;
for (Count = 0;Count<3 ;Count++ ) {
Values [Count] = Incre + 0.0f;
Incre += 0.1f;
System.out.println("Values [" + Count + "] : " + Values [Count]);
}
}
}
//OUTPUT:
//Values [0] : 0.1
//Values [1] : 0.2
//Values [2] : 0.3
This isn't the all and be all of assigning values to a specific array. Since I've seen the sample was 0.1 - 0.3 you could do it this way. This method is very useful if you're designing charts and graphs. You can have the x-value incremented by 0.1 until nth time.
Or you want to design some grid of some sort.
$(this).css('background-color', 'red');

significant security risk as anyone with access to the mysql
command may access your databases without a password. You may want
to close active shell sessions and/or disable shell access before
doing this):
# systemctl stop mysqld
# /usr/sbin/mysqld --skip-grant-tables -u mysql &
In your nonroot session, log in to mysql and set the mysql root password:
$ mysql
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
mysql> SET PASSWORD FOR 'root'@'localhost' = PASSWORD('MyNewPass');
Query OK, 0 rows affected, 1 warning (0.01 sec)
mysql> quit;
In your root session, kill the passwordless instance of mysqld and restore the normal mysqld listener to service:
# kill %1
# systemctl start mysqld
In your nonroot session, test the new root password you configured above:
$ mysql -u root -p
Enter password:
Welcome to the MySQL monitor. Commands end with ; or \g.

The problem it may cause if you do not synchronize before wait()
is as follows:
makeChangeOnX()
and checks the while condition, and it is true
(x.metCondition()
returns false
, means x.condition
is false
) so it will get inside it. Then just before the wait()
method, another thread goes to setConditionToTrue()
and sets the x.condition
to true
and notifyAll()
.wait()
method (not affected by the notifyAll()
that happened few moments before).
In this case, the 1st thread will stay waiting for another thread to perform setConditionToTrue()
, but that might not happen again.But if you put
synchronized
before the methods that change the object state, this will not happen.
class A {
private Object X;
makeChangeOnX(){
while (! x.getCondition()){
wait();
}
// Do the change
}
setConditionToTrue(){
x.condition = true;
notifyAll();
}
setConditionToFalse(){
x.condition = false;
notifyAll();
}
bool getCondition(){
return x.condition;
}
}
Lots of reasons for a floating point exception. Looking at your code your for loop seems to be a bit "incorrect". Looks like a possible division by zero.
for (i>0; i--;){
c= input%i;
Thats division by zero at some point since you are decrementing i.
It's very simple
const array1 = [
{id: 1, val: 60},
{id: 2, val: 2},
{id: 3, val: 89},
{id: 4, val: 78}
];
const array2 = [1,6,8,79,45,21,65,85,32,654];
const max = array1.reduce((acc, item) => acc = acc > item.val ? acc : item.val, 0);
const max2 = array2.reduce((acc, item) => acc = acc > item ? acc : item, 0);
console.log(max);
console.log(max2);

I use the package enumitem. You may then set such margins when you declare your lists (enumerate, description, itemize):
\begin{itemize}[leftmargin=0cm]
\item Foo
\item Bar
\end{itemize}
Naturally, the package provides lots of other nice customizations for lists (use 'label=' to change the bullet, use 'itemsep=' to change the spacing between items, etc...)
Here is a solution found at http://www.mrexcel.com/forum/excel-questions/510011-fails-activeworkbook-refreshall-backgroundquery-%3Dfalse.html:
Either have all the pivotcaches' backgroundquery properties set to False, or loop through all the workbook's pivotcaches:
Code:
For Each pc In ActiveWorkbook.PivotCaches
pc.BackgroundQuery = False
pc.Refresh
Next
this will leave all pivotcaches backgroundquery properties as false. You could retain each one's settings with:
Code:
For Each pc In ActiveWorkbook.PivotCaches
originalBGStatus = pc.BackgroundQuery
pc.BackgroundQuery = False
pc.Refresh
pc.BackgroundQuery = originalBGStatus
Next
You may supply extra argument for confirming a new image is posted.
Something like:
def save(self, new_image=False, *args, **kwargs):
if new_image:
small=rescale_image(self.image,width=100,height=100)
self.image_small=SimpleUploadedFile(name,small_pic)
super(Model, self).save(*args, **kwargs)
or pass request variable
def save(self, request=False, *args, **kwargs):
if request and request.FILES.get('image',False):
small=rescale_image(self.image,width=100,height=100)
self.image_small=SimpleUploadedFile(name,small_pic)
super(Model, self).save(*args, **kwargs)
I think these wont break your save when called simply.
You may put this in your admin.py so that this work with admin site too (for second of above solutions):
class ModelAdmin(admin.ModelAdmin):
....
def save_model(self, request, obj, form, change):
instance = form.save(commit=False)
instance.save(request=request)
return instance
Try this:
private void NewNumber()
{
Random a = new Random(Guid.newGuid().GetHashCode());
MyNumber = a.Next(0, 10);
}
Some Explnations:
Guid
: base on here : Represents a globally unique identifier (GUID)
Guid.newGuid()
produces a unique identifier like "936DA01F-9ABD-4d9d-80C7-02AF85C822A8"
and it will be unique in all over the universe base on here
Hash code here produce a unique integer from our unique identifier
so Guid.newGuid().GetHashCode()
gives us a unique number and the random class will produce real random numbers throw this
Sample: https://rextester.com/ODOXS63244
generated ten random numbers with this approach with result of:

Microsoft guidelines as checked by FxCop discourage use of List<T> in public APIs - prefer IList<T>.
Incidentally, I now almost always declare one-dimensional arrays as IList<T>, which means I can consistently use the IList<T>.Count property rather than Array.Length. For example:
public interface IMyApi
{
IList<int> GetReadOnlyValues();
}
public class MyApiImplementation : IMyApi
{
public IList<int> GetReadOnlyValues()
{
List<int> myList = new List<int>();
... populate list
return myList.AsReadOnly();
}
}
public class MyMockApiImplementationForUnitTests : IMyApi
{
public IList<int> GetReadOnlyValues()
{
IList<int> testValues = new int[] { 1, 2, 3 };
return testValues;
}
}

Delphi used properties and they have found their way into .NET (because it has the same architect).
In Delphi they are often used in combination with runtime type information such that the integrated property editor can be used to set the property in designtime.
Properties are not always related to fields. They can be functions that possible have side effects (but of course that is very bad design).
By default on Linux/Windows for an English keyboard the shortcut is Ctrl+Shift+/ to toggle a block comment, and Ctrl+/ to toggle a line comment.
If you go into Preferences->Key Bindings - Default
, you can find all the shortcuts, below are the lines for commenting.
{ "keys": ["ctrl+/"], "command": "toggle_comment", "args": { "block": false } },
{ "keys": ["ctrl+shift+/"], "command": "toggle_comment", "args": { "block": true } },
git status
is your friend, use it often. Good for answering questions like:
Unlike, say svn status
, git status
runs nigh-instantly even on large projects. I often found it reassuring while learning git to use it frequently, to make sure my mental model of what was going on was accurate. Now I mostly just use it to remind myself what I've changed since my last commit.
Obviously, it's much more useful if your .gitignore is sanely configured.
Just a small addition to Nick's answer (which works great !) :
If you want to allow spaces in between letters, for example , you may restrict to enter only letters in full name, but it should allow space as well - just list the space as below with a comma. And in the same way if you need to allow any other specific character:
jQuery.validator.addMethod("lettersonly", function(value, element)
{
return this.optional(element) || /^[a-z," "]+$/i.test(value);
}, "Letters and spaces only please");
I did some research on this by using different methods to assign values to a nullable int. Here is what happened when I did various things. Should clarify what's going on.
Keep in mind: Nullable<something>
or the shorthand something?
is a struct for which the compiler seems to be doing a lot of work to let us use with null as if it were a class.
As you'll see below, SomeNullable == null
and SomeNullable.HasValue
will always return an expected true or false. Although not demonstrated below, SomeNullable == 3
is valid too (assuming SomeNullable is an int?
).
While SomeNullable.Value
gets us a runtime error if we assigned null
to SomeNullable
. This is in fact the only case where nullables could cause us a problem, thanks to a combination of overloaded operators, overloaded object.Equals(obj)
method, and compiler optimization and monkey business.
Here is a description of some code I ran, and what output it produced in labels:
int? val = null;
lbl_Val.Text = val.ToString(); //Produced an empty string.
lbl_ValVal.Text = val.Value.ToString(); //Produced a runtime error. ("Nullable object must have a value.")
lbl_ValEqNull.Text = (val == null).ToString(); //Produced "True" (without the quotes)
lbl_ValNEqNull.Text = (val != null).ToString(); //Produced "False"
lbl_ValHasVal.Text = val.HasValue.ToString(); //Produced "False"
lbl_NValHasVal.Text = (!(val.HasValue)).ToString(); //Produced "True"
lbl_ValValEqNull.Text = (val.Value == null).ToString(); //Produced a runtime error. ("Nullable object must have a value.")
lbl_ValValNEqNull.Text = (val.Value != null).ToString(); //Produced a runtime error. ("Nullable object must have a value.")
Ok, lets try the next initialization method:
int? val = new int?();
lbl_Val.Text = val.ToString(); //Produced an empty string.
lbl_ValVal.Text = val.Value.ToString(); //Produced a runtime error. ("Nullable object must have a value.")
lbl_ValEqNull.Text = (val == null).ToString(); //Produced "True" (without the quotes)
lbl_ValNEqNull.Text = (val != null).ToString(); //Produced "False"
lbl_ValHasVal.Text = val.HasValue.ToString(); //Produced "False"
lbl_NValHasVal.Text = (!(val.HasValue)).ToString(); //Produced "True"
lbl_ValValEqNull.Text = (val.Value == null).ToString(); //Produced a runtime error. ("Nullable object must have a value.")
lbl_ValValNEqNull.Text = (val.Value != null).ToString(); //Produced a runtime error. ("Nullable object must have a value.")
All the same as before. Keep in mind that initializing with int? val = new int?(null);
, with null passed to the constructor, would have produced a COMPILE time error, since the nullable object's VALUE is NOT nullable. It is only the wrapper object itself that can equal null.
Likewise, we would get a compile time error from:
int? val = new int?();
val.Value = null;
not to mention that val.Value
is a read-only property anyway, meaning we can't even use something like:
val.Value = 3;
but again, polymorphous overloaded implicit conversion operators let us do:
val = 3;
No need to worry about polysomthing whatchamacallits though, so long as it works right? :)

I noticed "[" indexing columns fails to create levels when iterating:
for ( a_feature in convert.to.factors) {
feature.df[a_feature] <- factor(feature.df[a_feature]) }
It creates, e.g. for the "Status" column:
Status : Factor w/ 1 level "c(\"Success\", \"Fail\")" : NA NA NA ...
Which is remedied by using "[[" indexing:
for ( a_feature in convert.to.factors) {
feature.df[[a_feature]] <- factor(feature.df[[a_feature]]) }
Giving instead, as desired:
. Status : Factor w/ 2 levels "Success", "Fail" : 1 1 2 1 ...

If you are seeing only part of your request payload, you need to call the setMaxPayloadLength
function as it defaults to showing only 50 characters in your request body. Also, setting setIncludeHeaders
to false is a good idea if you don't want to log your auth headers!
@Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
CommonsRequestLoggingFilter loggingFilter = new CommonsRequestLoggingFilter();
loggingFilter.setIncludeClientInfo(false);
loggingFilter.setIncludeQueryString(false);
loggingFilter.setIncludePayload(true);
loggingFilter.setIncludeHeaders(false);
loggingFilter.setMaxPayloadLength(500);
return loggingFilter;
}
By far the best tool I have used for reverse engineering, and round tripping java -> UML is Borland's Together. It is based on Eclipse (not just a single plugin) and really works well.

If using sqlplus you can define a variable thus:
define <varname>=<varvalue>
And you can display the value by:
define <varname>
And then use it in a query as, for example:
select *
from tab1
where col1 = '&varname';
This works:
insert into TABLE_NAME (COL1,COL2)
select my_seq.nextval, a
from
(SELECT 'SOME VALUE' as a FROM DUAL
UNION ALL
SELECT 'ANOTHER VALUE' FROM DUAL)
// woot, global var. I havent done this for a long time.
For future googlers (thousands have now googled this question):
To set your mind at ease, the onClick
event does work with divs in react, so double-check your code syntax.
These are right:
<div onClick={doThis}>
<div onClick={() => doThis()}>
These are wrong:
<div onClick={doThis()}>
<div onClick={() => doThis}>
(and don't forget to close your tags... Watch for this:
<div onClick={doThis}
missing closing tag on the div)
A possible workaround for the page title:
document.title = "Print page title"; window.print();
This should work in every browser.

A simple and proper way I've found to Handle Checked/Unchecked events using MVVM pattern is the Following, with Caliburn.Micro :
<CheckBox IsChecked="{Binding IsCheckedBooleanProperty}" Content="{DynamicResource DisplayContent}" cal:Message.Attach="[Event Checked] = [Action CheckBoxClicked()]; [Event Unchecked] = [Action CheckBoxClicked()]" />
And implement a Method CheckBoxClicked() in the ViewModel, to do stuff you want.
import datetime
timestamp = datetime.datetime.fromtimestamp(1500000000)

I optimized the answers with the following points:
if (cond) { stmt; }
as cond && stmt;
I'll present two solutions, one using forEach, the other using reduce:
Solution 1: Using forEach
var options = [_x000D_
{ name: 'One', assigned: true }, _x000D_
{ name: 'Two', assigned: false }, _x000D_
{ name: 'Three', assigned: true }, _x000D_
];_x000D_
var reduced = []_x000D_
options.forEach(o => {_x000D_
o.assigned && reduced.push( { name: o.name, newProperty: 'Foo' } );_x000D_
} );_x000D_
console.log(reduced);
_x000D_
Solution 2: Using reduce
var options = [_x000D_
{ name: 'One', assigned: true }, _x000D_
{ name: 'Two', assigned: false }, _x000D_
{ name: 'Three', assigned: true }, _x000D_
];_x000D_
var reduced = options.reduce((a, o) => {_x000D_
o.assigned && a.push( { name: o.name, newProperty: 'Foo' } );_x000D_
return a;_x000D_
}, [ ] );_x000D_
console.log(reduced);
_x000D_
I leave it up to you to decide which solution to go for.
Have you installed drivers for the phone? http://developer.android.com/sdk/win-usb.html
It appears that the the sdk does not "install" the USB drivers. You can select that usb drivers in the sdk to see the file location, open that up, and right click to install the driver yourself.
If above doesn't work, @Abir Hasan appears to have another method in answers below.
Here's probably what you are looking for: php-get-url-query-string. You can combine it with other suggested $_SERVER
parameters.
The strange part is that I don't see a main function anywhere.
That is exactly your problem. The project merely creates a DLL. It has no executable to run.
You will need to add a second project, which is an executable which references the other project, and calls something in it.
== Equality operator evaluates the arguments after converting them to numbers. So string zero "0" is converted to Number data type and boolean false is converted to Number 0. So
"0" == false // true
Same applies to `
false == "0" //true
=== Strict equality check evaluates the arguments with the original data type
"0" === false // false, because "0" is a string and false is boolean
Same applies to
false === "0" // false
In
if("0") console.log("ha");
The String "0" is not comparing with any arguments, and string is a true value until or unless it is compared with any arguments. It is exactly like
if(true) console.log("ha");
But
if (0) console.log("ha"); // empty console line, because 0 is false

If you want to exclude the sample controller's sample action
class TestController < ApplicationController
protect_from_forgery :except => [:sample]
def sample
render json: @hogehoge
end
end
You can to process requests from outside without any problems.
you can use for example:
>>> test_list = ['title', 'email', 'password2', 'password1', 'first_name',
'last_name', 'next', 'newsletter']
>>> reorder_func = lambda x: x.insert(x.index('password2'), x.pop(x.index('password2')+1))
>>> reorder_func(test_list)
>>> test_list
... ['title', 'email', 'password1', 'password2', 'first_name', 'last_name', 'next', 'newsletter']
First, install QEMU. On Debian-based distributions like Ubuntu, run:
$ apt-get install qemu
Then run the following command:
$ qemu-img convert -O vmdk imagefile.dd vmdkname.vmdk
I’m assuming a flat disk image is a dd
-style image. The convert operation also handles numerous other formats.
For more information about the qemu-img
command, see the output of
$ qemu-img -h
Before I show you how to reload / refresh model data from the server programmatically? I have to explain for you the concept of Data Binding. This is an extremely powerful concept that will truly revolutionize the way you develop. So may be you have to read about this concept from this link or this seconde link in order to unterstand how AngularjS work.
now I'll show you a sample example that exaplain how can you update your model from server.
HTML Code:
<div ng-controller="PersonListCtrl">
<ul>
<li ng-repeat="person in persons">
Name: {{person.name}}, Age {{person.age}}
</li>
</ul>
<button ng-click="updateData()">Refresh Data</button>
</div>
So our controller named: PersonListCtrl and our Model named: persons. go to your Controller js in order to develop the function named: updateData()
that will be invoked when we are need to update and refresh our Model persons.
Javascript Code:
app.controller('adsController', function($log,$scope,...){
.....
$scope.updateData = function(){
$http.get('/persons').success(function(data) {
$scope.persons = data;// Update Model-- Line X
});
}
});
Now I explain for you how it work:
when user click on button Refresh Data, the server will call to function updateData() and inside this function we will invoke our web service by the function $http.get()
and when we have the result from our ws we will affect it to our model (Line X).Dice that affects the results for our model, our View of this list will be changed with new Data.
I have an alternative to the methods above that used the ALT tag and a CSS selector on the alt tag... Instead, add a URL hash like this:
First your Markdown image code:
![my image](/img/myImage.jpg#left)
![my image](/img/myImage.jpg#right)
![my image](/img/myImage.jpg#center)
Note the added URL hash #center.
Now add this rule in CSS using CSS 3 attribute selectors to select images with a certain path.
img[src*='#left'] {
float: left;
}
img[src*='#right'] {
float: right;
}
img[src*='#center'] {
display: block;
margin: auto;
}
You should be able to use a URL hash like this almost like defining a class name and it isn't a misuse of the ALT tag like some people had commented about for that solution. It also won't require any additional extensions. Do one for float right and left as well or any other styles you might want.
For those of you who are using MacOS and like me perhaps have been circling the internet as to why some R packages do not install here is a possible help.
If you get a non-zero exit status first check to ensure all dependencies are installed as well. Read through the messaging. If that is checked off, then look for indications such as gfortran: No such a file or directory. That might be due to Apple OS compiler issues that some packages will not install unless you use their binary version. Look for binary zip file in the package cran.r-project.org page, download it and use the following command to get the package installed:
install.packages("/PATH/zip file ", repos = NULL, type="source")

First off, BigDecimal.multiply()
returns a BigDecimal
and you're trying to store that in an int
.
Second, it takes another BigDecimal
as the argument, not an int
.
If you just use the BigDecimal
for all variables involved in these calculations, it should work fine.
I agree with CupawnTae.
SET
is not useful for changes to the master environment.
FYI: System variables are in HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment
(a good deal longer than user vars).
The full command for a system var named FOOBAR therefore is:
REG delete "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment" /F /V FOOBAR
(Note the quotes required to handle the space.)
It is too bad the setx
command doesn't support a delete syntax. :(
PS: Use responsibly - If you kill your path variable, don't blame me!
Exception code c0000005
is the code for an access violation. That means that your program is accessing (either reading or writing) a memory address to which it does not have rights. Most commonly this is caused by:
N
and you access elements with index >=N
.To solve the problem you'll need to do some debugging. If you are not in a position to get the fault to occur under your debugger on your development machine you should get a crash dump file and load it into your debugger. This will allow you to see where in the code the problem occurred and hopefully lead you to the solution. You'll need to have the debugging symbols associated with the executable in order to see meaningful stack traces.
For .net core 2.1 console application, the following approaches worked for me:
1 - from CLI (after building the application and navigating to debug or release folders based on the build type specified):
dotnet appName.dll
2 - from Visual Studio
R.C solution and click publish
'Target location' -> 'configure' ->
'Deployment Mode' = 'Self-Contained'
'Target Runtime' = 'win-x64 or win-x86 depending on the OS'
References:
For an in depth explanation of all the deployment options available for .net core applications, checkout the following articles:
Considering you have a datetime
object called d
,
use the following to get the timestamp in UTC:
d.strftime("%Y-%m-%dT%H:%M:%S.%fZ")
And for the opposite direction, use following :
d = datetime.strptime("2008-09-03T20:56:35.450686Z", "%Y-%m-%dT%H:%M:%S.%fZ")
You can use howfat which also displays dependency statistics:
npx howfat -r tree jasmine
I usually use information_Schema.columns
and information_schema.tables
, although like @yuck said, sys.tables
and sys.columns
are shorter to type.
In a loop, concatenate these
@sql = @sql + 'select' + column_name +
' from ' + table_name +
' where ' + column_name ' like ''%''+value+''%' UNION
Then execute the resulting sql.
Your server tells you exactly what you need : [Hint: SSLProxyEngine]
You need to add that directive to your VirtualHost
before the Proxy
directives :
SSLProxyEngine on
ProxyPass /primary/store https://localhost:9763/store/
ProxyPassReverse /primary/store https://localhost:9763/store/
Check this following WPF Project which decodes the properties correctly.
Java VM contains a single class object per class. Each class may have some shared variables called static variables. If the critical section of the code plays with these variables in a concurrent environment, then we need to make that particular section as synchronized. When there is more than one static synchronized method only one of them will be executed at a time without preemption. That's what lock on class object does.
You could try something like:
var Title = $('<textarea />').html("Chris' corner").text();_x000D_
console.log(Title);
_x000D_

$('form').submit(function() {_x000D_
var theString = $('#string').val();_x000D_
var varTitle = $('<textarea />').html(theString).text();_x000D_
$('#output').text(varTitle);_x000D_
return false;_x000D_
});

You can just add the word vectors of one sentence together. Then count the Cosine similarity of two sentence vector as the similarity of two sentence. I think that's the most easy way.
The flexbox way:
.foo {
display: flex;
align-items: center;
justify-content: center;
height: 50px;
}
To my knowledge, there is sadly no CSS filter to colorise an element (perhaps with the use of some SVG filter magic, but I'm somewhat unfamiliar with that) and even if that wasn't the case, filters are basically only supported by webkit browsers.
With that said, you could still work around this and use a canvas
to modify your image. Basically, you can draw an image element onto a canvas and then loop through the pixels, modifying the respective RGBA values to the colour you want.
However, canvases do come with some restrictions. Most importantly, you have to make sure that the image src comes from the same domain as the page. Otherwise the browser won't allow you to read or modify the pixel data of the canvas.
Here's a JSFiddle changing the colour of the JSFiddle logo.

I ran into this problem a few times. Many of the solutions will run the rm
command for each individual file that needs to be deleted. This is very inefficient:
find . -name "*.pdf" -print0 | xargs -0 rm -rf
I ended up writing a python script to delete the files based on the first 4 characters in the file-name:
import os
filedir = '/tmp/' #The directory you wish to run rm on
filelist = (os.listdir(filedir)) #gets listing of all files in the specified dir
newlist = [] #Makes a blank list named newlist
for i in filelist:
if str((i)[:4]) not in newlist: #This makes sure that the elements are unique for newlist
newlist.append((i)[:4]) #This takes only the first 4 charcters of the folder/filename and appends it to newlist
for i in newlist:
if 'tmp' in i: #If statment to look for tmp in the filename/dirname
print ('Running command rm -rf '+str(filedir)+str(i)+'* : File Count: '+str(len(os.listdir(filedir)))) #Prints the command to be run and a total file count
os.system('rm -rf '+str(filedir)+str(i)+'*') #Actual shell command
print ('DONE')
This worked very well for me. I was able to clear out over 2 million temp files in a folder in about 15 minutes. I commented the tar out of the little bit of code so anyone with minimal to no python knowledge can manipulate this code.

You can't do this with the column annotation. I think the only way is to set the default value when a object is created. Maybe the default constructor would be the right place to do that.
JSX:
<select value={ this.state.foo } onChange={this.handleFooChange}>
<option value="A">A</option>
<option value="B">B</option>
</select>
TypeScript:
private handleFooChange = (event: React.FormEvent<HTMLSelectElement>) => {
const element = event.target as HTMLSelectElement;
this.setState({ foo: element.value });
}
