use this command for run every service just write name service for example :
for xrdp :
sudo /etc/init.d/xrdp start
for redis :
sudo /etc/init.d/redis start
(for any other service, check the init.d folder for filenames)
I actually used the answer from How do I run a node.js app as a background service? combined with what dwrz said above. In my case, I was creating a Discord bot that needed to be able to run when I was not around.
With this service in place, I initially got the same error that the initial poster did, which brought me here. I was missing the #!/usr/bin/env node
at the top of my executed node.js script.
Since then, no problems, although I intend to see what else can be extended to the service itself.
The output of ps aux
looks like you did not start docker through systemd/systemctl.
It looks like you started it with:
sudo dockerd -H gridsim1103:2376
When you try to stop it with systemctl, nothing should happen as the resulting dockerd process is not controlled by systemd. So the behavior you see is expected.
The correct way to start docker is to use systemd/systemctl:
systemctl enable docker
systemctl start docker
After this, docker should start on system start.
EDIT: As you already have the docker process running, simply kill it by pressing CTRL+C on the terminal you started it. Or send a kill signal to the process.
open my.cnf and copy the log-error
path
then check the permission for the copied log file using
$ ls -l /var/log/mysql.log
if any log file permission may changed from mysql:mysql, please change the file permission to
$ chown -R mysql:mysql /var/log/mysql.log
then restart the mysql server
$ service mysql restart || systemctl restart mysqld
note: this kind of errors formed by the permission issues. all the mysql service start commands using the log file for writing the status of mysql. If the permission has been changed, the service can't be write anything into the log files. If it happens it will stopped to run the service
If you already have a config.json file then the final file should look something like this...
Here registry.myprivate.com
is the one which was giving me problems.
{
"auths": {
"https://index.docker.io/v1/": {
"auth": "xxxxxxxxxxxxxxxxxxxx=="
},
"registry.myprivate.com": {
"auth": "xxxxxxxxxxxxxxxxxxxx="
}
},
"HttpHeaders": {
"User-Agent": "Docker-Client/19.03.8 (linux)"
},
"insecure-registries" : ["registry.myprivate.com"]
}
It work's using rules
instead of loaders
module : {
rules : [
{
test : /\.jsx?/,
include : APP_DIR,
loader : 'babel-loader'
}
]
}
In my case I were starting jenkins service from root instead of jenkins user
i did
sed -i 's/JENKINS_USER="jenkins"/JENKINS_USER="root"/g /etc/sysconfig/jenkins
then
service jenkins restart
all work well
Ubuntu 14 and lower does not have "systemctl
" Source: https://docs.docker.com/install/linux/linux-postinstall/#configure-docker-to-start-on-boot
Configure Docker to start on boot:
Most current Linux distributions (RHEL, CentOS, Fedora, Ubuntu 16.04 and higher) use systemd to manage which services start when the system boots. Ubuntu 14.10 and below use upstart.
1) systemd (Ubuntu 16 and above):
$ sudo systemctl enable docker
To disable this behavior, use disable instead.
$ sudo systemctl disable docker
2) upstart (Ubuntu 14 and below):
Docker is automatically configured to start on boot using upstart. To disable this behavior, use the following command:
$ echo manual | sudo tee /etc/init/docker.override
chkconfig
$ sudo chkconfig docker on
Done.
I got the same error because of a simple typo in vhost.conf. Remember to make sure you don't have any errors in the config files.
apachectl configtest
I suggest using the official pkg on Mac. I guess docker-compose is no longer included with docker by default: https://docs.docker.com/toolbox/toolbox_install_mac/
There's no need to set a fact.
- shell: cat "hello"
register: cat_contents
- shell: echo "I cat hello"
when: cat_contents.stdout == "hello"
This worked for me:
First, go to
and make the changes in nginx.conf and make the default port to listen from 80 to any of your choice 85 or something.
Then use this command to bind that port type for nginx to use it:
where PORT_TYPE is one of the following: http_cache_port_t, http_port_t, jboss_management_port_t, jboss_messaging_port_t, ntop_port_t, puppet_port_t.
Then run:
[you should see active status]; #sudo systemctl enable nginx
S3N is not a default file format. You need to build your version of Spark with a version of Hadoop that has the additional libraries used for AWS compatibility. Additional info I found here, https://www.hakkalabs.co/articles/making-your-local-hadoop-more-like-aws-elastic-mapreduce
struct Connectivity {
static let sharedInstance = NetworkReachabilityManager()!
static var isConnectedToInternet:Bool {
return self.sharedInstance.isReachable
}
}
Now call it
if Connectivity.isConnectedToInternet{
call_your_methods_here()
} else{
show_alert_for_noInternet()
}
Put the IPtables configuration in the traditional file and it will be loaded after boot:
/etc/sysconfig/iptables
When you clone project from somewhere which uses Cocoapods you need to install them to your project.
Here step-by-step what you need to do:
Good luck!
In my case the issue was caused by the JDK version. To solve this I suggest to go into your pom file and check the <jdk.version>1.7</jdk.version>.
Afterwards check java version in your cmd(windows) or terminal ( OSX or LINUX ) by typing : java -version.
Compare the version shown in the terminal\command prompt with what you have in your pom file. Make sure they are the same. Then run your project again.
To attempt command line arguments directly is not possible.
One alternative might be environment variables (https://superuser.com/questions/728951/systemd-giving-my-service-multiple-arguments).
This is where I found the answer: http://www.freedesktop.org/software/systemd/man/systemctl.html
so sudo systemctl restart myprog -v
-- systemctl will think you're trying to set one of its flags, not myprog's flag.
sudo systemctl restart myprog someotheroption
-- systemctl will restart myprog and the someotheroption service, if it exists.
The main thread here seems to be a corrupted user account profile for the account that is used to start the DB engine. This is the account that was specified for the "SQL Server Database" engine during installation. In the setup event log, it's also indicated by the following entry:
SQLSVCACCOUNT: NT AUTHORITY\SYSTEM
According to the link provided by @royki:
The root cause of this issue, in most cases, is that the profile of the user being used for the service account (in my case it was local system) is corrupted.
This would explain why other respondents had success after changing to different accounts:
To fix the user profile that's causing the error, follow the steps listed KB947215.
The main steps from KB947215 are summarized as follows:-
regedit
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList
Navigate to the SID for the corrupted profile
To find the SID, click on each SID GUID, review the value for the ProfileImagePath
value, and see if it's the correct account. For system accounts, there's a different way to know the SID for the account that failed:
The main system account SIDs of interest are:
SID Name Also Known As
S-1-5-18 Local System NT AUTHORITY\SYSTEM
S-1-5-19 LocalService NT AUTHORITY\LOCAL SERVICE
S-1-5-20 NetworkService NT AUTHORITY\NETWORK SERVICE
For information on additional SIDs, see Well-known security identifiers in Windows operating systems.

I had similar issue with creating custom TableCell. The issue was that I set FileOwner to my custom class and then connected outlets.
FileOwner should remain NSObject.
In case there is a possibility for dataloss EF does not complete the update-database command since AutomaticMigrationDataLossAllowed = false by default, and roolbacks the action unless you run it with the -force parameter.
Update-Database –TargetMigration:"Your migration name" -force
or
Update-Database –TargetMigration:Your_Migration_Index -force
The Runnable
interface is another way in which you can implement multi-threading other than extending the Thread
class due to the fact that Java allows you to extend only one class.
You can however, use the new Thread(Runnable runnable) constructor, something like this:
private Thread thread = new Thread(new Runnable() {
public void run() {
final long start = mStartTime;
long millis = SystemClock.uptimeMillis() - start;
int seconds = (int) (millis / 1000);
int minutes = seconds / 60;
seconds = seconds % 60;
if (seconds < 10) {
mTimeLabel.setText("" + minutes + ":0" + seconds);
} else {
mTimeLabel.setText("" + minutes + ":" + seconds);
}
mHandler.postAtTime(this,
start + (((minutes * 60) + seconds + 1) * 1000));
}
});
thread.start();
Yes, they have deprecated the previous buildSessionFactory API, and it's quite easy to do well.. you can do something like this..
EDIT : ServiceRegistryBuilder is deprecated. you must use StandardServiceRegistryBuilder
public void testConnection() throws Exception {
logger.info("Trying to create a test connection with the database.");
Configuration configuration = new Configuration();
configuration.configure("hibernate_sp.cfg.xml");
StandardServiceRegistryBuilder ssrb = new StandardServiceRegistryBuilder().applySettings(configuration.getProperties());
SessionFactory sessionFactory = configuration.buildSessionFactory(ssrb.build());
Session session = sessionFactory.openSession();
logger.info("Test connection with the database created successfuly.");
}
For more reference and in depth detail, you can check the hibernate's official test case at https://github.com/hibernate/hibernate-orm/blob/master/hibernate-testing/src/main/java/org/hibernate/testing/junit4/BaseCoreFunctionalTestCase.java function (buildSessionFactory()).
The number of map tasks for a given job is driven by the number of input splits and not by the mapred.map.tasks parameter. For each input split a map task is spawned. So, over the lifetime of a mapreduce job the number of map tasks is equal to the number of input splits. mapred.map.tasks is just a hint to the InputFormat for the number of maps.
In your example Hadoop has determined there are 24 input splits and will spawn 24 map tasks in total. But, you can control how many map tasks can be executed in parallel by each of the task tracker.
Also, removing a space after -D might solve the problem for reduce.
For more information on the number of map and reduce tasks, please look at the below url
https://cwiki.apache.org/confluence/display/HADOOP2/HowManyMapsAndReduces
At the risk of sounding obvious, always check the spelling of your forward class files. Sometimes XCode (at least XCode 4.3.2) will turn a declaration green that's actually camel cased incorrectly. Like in this example:
"_OBJC_CLASS_$_RadioKit", referenced from:
objc-class-ref in RadioPlayerViewController.o
If RadioKit was a class file and you make it a property of another file, in the interface declaration, you might see that
Radiokit *rk;
has "Radiokit" in green when the actual decalaration should be:
RadioKit *rk;
This error will also throw this type of error. Another example (in my case), is when you have _iPhone and _iphone extensions on your class names for universal apps. Once I changed the appropriate file from _iphone to the correct _iPhone, the errors went away.
I just add this line exactly as it appears below (if you need a second delay):
try {
Thread.sleep(1000);
} catch(InterruptedException e) {
// Process exception
}
I find the catch IS necessary (Your app can crash due to Android OS as much as your own code).
The solution of this problem is very simple Just go to the directory where the project installed and open the file with extension ".xcworkspace"
That will solve the problem .
The easiest way I found:
<Setter Property="Focusable" Value="false"/>
SET @uids := "";
UPDATE myf___ingtable
SET id = id
WHERE id < 5
AND ( SELECT @uids := CONCAT_WS(',', CAST(id AS CHAR CHARACTER SET utf8), @uids) );
SELECT @uids;
I had to CAST the id (dunno why)... or I cannot get the @uids content (it was a blob) Btw many thanks for Pomyk answer!
I use git from cygwin on Windows, the git apply
solution doesn't work for me. Here is my solution, run chmod
on every file to reset its permissions.
#!/bin/bash
IFS=$'\n'
for c in `git diff -p |sed -n '/diff --git/{N;s/diff --git//g;s/\n/ /g;s# a/.* b/##g;s/old mode //g;s/\(.*\) 100\(.*\)/chmod \2 \1/g;p}'`
do

Late to the party, but for posterity, the stringr package (part of the popular "tidyverse" suite of packages) now provides functions with harmonised signatures for string handling:
string <- c("G1:E001", "G2:E002", "G3:E003")
# match string to keep
stringr::str_extract(string = string, pattern = "E[0-9]+")
# [1] "E001" "E002" "E003"
# replace leading string with ""
stringr::str_remove(string = string, pattern = "^.*:")
# [1] "E001" "E002" "E003"

Just to generalize Rob's answer a little, if you're not doing it on output, you can still use the same interface with sprintf()
.
I think there is another way to do it, though. You can try ceil()
and floor()
to round up and down. A nice trick is to add 0.5, so anything over 0.5 rounds up but anything under it rounds down. ceil()
and floor()
only work on double
s though.
EDIT: Also, for floats, you can use truncf()
to truncate floats. The same +0.5 trick should work to do accurate rounding.
public static final long SECOND_IN_MILLIS = 1000;
public static final long MINUTE_IN_MILLIS = SECOND_IN_MILLIS * 60;
public static final long HOUR_IN_MILLIS = MINUTE_IN_MILLIS * 60;
public static final long DAY_IN_MILLIS = HOUR_IN_MILLIS * 24;
public static final long WEEK_IN_MILLIS = DAY_IN_MILLIS * 7;
You could cast int but I would recommend using long.
Direct Javascript calls between frames and/or windows are only allowed if they conform to the same-origin policy. If your window and iframe share a common parent domain you can set document.domain
to "domain lower") one or both such that they can communicate. Otherwise you'll need to look into something like the postMessage() API.
The below regex would match white spaces but not of a new line character.
(?:(?!\n)\s)
If you want to add carriage return also then add \r
with the |
operator inside the negative lookahead.
(?:(?![\n\r])\s)
Add +
after the non-capturing group to match one or more white spaces.
(?:(?![\n\r])\s)+
I don't know why you people failed to mention the POSIX character class [[:blank:]]
which matches any horizontal whitespaces (spaces and tabs). This POSIX chracter class would work on BRE(Basic REgular Expressions), ERE(Extended Regular Expression), PCRE(Perl Compatible Regular Expression).
/**
* @param filePath
* @param fs
* @return list of absolute file path present in given path
* @throws FileNotFoundException
* @throws IOException
*/
public static List<String> getAllFilePath(Path filePath, FileSystem fs) throws FileNotFoundException, IOException {
List<String> fileList = new ArrayList<String>();
FileStatus[] fileStatus = fs.listStatus(filePath);
for (FileStatus fileStat : fileStatus) {
if (fileStat.isDirectory()) {
fileList.addAll(getAllFilePath(fileStat.getPath(), fs));
} else {
fileList.add(fileStat.getPath().toString());
}
}
return fileList;
}
Quick Example : Suppose you have the following file structure:
a -> b
-> c -> d
-> e
-> d -> f
Using the code above, you get:
a/b
a/c/d
a/c/e
a/d/f
If you want only the leaf (i.e. fileNames), use the following code in else
block :
...
} else {
String fileName = fileStat.getPath().toString();
fileList.add(fileName.substring(fileName.lastIndexOf("/") + 1));
}
This will give:
b
d
e
f
getElementById
Return Value: An Element Object, representing an element with the specified ID. Returns null if no elements with the specified ID exists see: https://www.w3schools.com/jsref/met_document_getelementbyid.asp
Truthy vs Falsy
In JavaScript, a truthy value is a value that is considered true when evaluated in a Boolean context. All values are truthy unless they are defined as falsy (i.e., except for false, 0, "", null, undefined, and NaN). see: https://developer.mozilla.org/en-US/docs/Glossary/Truthy
When the dom element is not found in the document
it will return null
. null is a Falsy and can be used as boolean expression
in the if statement.
var myElement = document.getElementById("myElement");
if(myElement){
// Element exists
}
You can chain .fail()
callback for error response.
$.get('http://example.com/page/2/', function(data){
$(data).find('#reviews .card').appendTo('#reviews');
})
.fail(function() {
//Error logic
})
I have a full discussion of events and delegates in my events article. For the simplest kind of event, you can just declare a public event and the compiler will create both an event and a field to keep track of subscribers:
public event EventHandler Foo;
If you need more complicated subscription/unsubscription logic, you can do that explicitly:
public event EventHandler Foo
{
add
{
// Subscription logic here
}
remove
{
// Unsubscription logic here
}
}
I tried all the provided solutions (forking, systemloader, more memory etc..), nothing worked.
Environment: The build failed in gitlab ci environment, running the build inside a docker container.
Solution: We used surefireplugin in version 2.20.1 and upgrading to 2.21.0 or greater (we used 2.22.1) fixed the issue.
Cause:
SUREFIRE-1422 - surefire uses the command ps
, which wasnt available in the docker environment and led to the "crash". This issue is fixed in 2.21.0 or greater.
Thanks to this answer from another question: https://stackoverflow.com/a/50568662/2970422
Sometimes the column you want to filter may appear in a different position than column index 2 or have a variable name.
In this case, you can simply refer the column name you want to filter as:
columnNameToFilter = "cell_type"
expr[expr[[columnNameToFilter]] == "hesc", ]
The following configs works on Cent OS 6 or earlier
As stated above first have to disable selinux.
Step 1 nano /etc/sysconfig/selinux
Make sure the file has this configurations
SELINUX=disabled
SELINUXTYPE=targeted
Then restart the system
Step 2
iptables -A INPUT -m state --state NEW -p tcp --dport 8080 -j ACCEPT
Step 3
sudo service iptables save
For Cent OS 7
step 1
firewall-cmd --zone=public --permanent --add-port=8080/tcp
Step 2
firewall-cmd --reload
HTML
<div id="mydiv" data-myval="10"></div>
JS
var a = $('#mydiv').data('myval'); //getter
$('#mydiv').data('myval',20); //setter
From the reference:
jQuery itself uses the
.data()
method to save information under the names 'events' and 'handle', and also reserves any data name starting with an underscore ('_') for internal use.
It should be noted that jQuery's data()
doesn't change the data
attribute in HTML.
So, if you need to change the data
attribute in HTML, you should use .attr()
instead.
HTML
<div id="outer">
<div id="mydiv" data-myval="10"></div>
</div>
?JS:
alert($('#outer').html()); // alerts <div id="mydiv" data-myval="10"> </div>
var a = $('#mydiv').data('myval'); //getter
$('#mydiv').attr("data-myval","20"); //setter
alert($('#outer').html()); //alerts <div id="mydiv" data-myval="20"> </div>

Querying for a Date Range (Specific Month or Day) in the MongoDB Cookbook has a very good explanation on the matter, but below is something I tried out myself and it seems to work.
items.save({
name: "example",
created_at: ISODate("2010-04-30T00:00:00.000Z")
})
items.find({
created_at: {
$gte: ISODate("2010-04-29T00:00:00.000Z"),
$lt: ISODate("2010-05-01T00:00:00.000Z")
}
})
=> { "_id" : ObjectId("4c0791e2b9ec877893f3363b"), "name" : "example", "created_at" : "Sun May 30 2010 00:00:00 GMT+0300 (EEST)" }
Based on my experiments you will need to serialize your dates into a format that MongoDB supports, because the following gave undesired search results.
items.save({
name: "example",
created_at: "Sun May 30 18.49:00 +0000 2010"
})
items.find({
created_at: {
$gte:"Mon May 30 18:47:00 +0000 2015",
$lt: "Sun May 30 20:40:36 +0000 2010"
}
})
=> { "_id" : ObjectId("4c079123b9ec877893f33638"), "name" : "example", "created_at" : "Sun May 30 18.49:00 +0000 2010" }
In the second example no results were expected, but there was still one gotten. This is because a basic string comparison is done.
the implementation in the cpp file should be in the form
gameObject::gameObject()
{
x = 0;
y = 0;
}
gameObject::gameObject(int inx, int iny)
{
x = inx;
y = iny;
}
gameObject::~gameObject()
{
//
}
int gameObject::add()
{
return x+y;
}
not within a class gameObject { } definition block
I was looking for the same solution and Pawel gave me 99% of the answer. The only thing that was missing that I needed for the Extension to display was adding the following Razor Code into the cshtml(view) page:
@using programname.Models.Extensions
I was looking for the FirstName, to display in the top right of my NavBar after the user logged in.
I thought I would post this incase it helps someone else, So here is my code:
I created a new folder called Extensions(Under my Models Folder) and created the new class as Pawel specified above: IdentityExtensions.cs
using System.Security.Claims;
using System.Security.Principal;
namespace ProgramName.Models.Extensions
{
public static class IdentityExtensions
{
public static string GetUserFirstname(this IIdentity identity)
{
var claim = ((ClaimsIdentity)identity).FindFirst("FirstName");
// Test for null to avoid issues during local testing
return (claim != null) ? claim.Value : string.Empty;
}
}
}
IdentityModels.cs
:
public class ApplicationUser : IdentityUser
{
//Extended Properties
public string FirstName { get; internal set; }
public string Surname { get; internal set; }
public bool isAuthorized { get; set; }
public bool isActive { get; set; }
public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
{
// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);
// Add custom user claims here
userIdentity.AddClaim(new Claim("FirstName", this.FirstName));
return userIdentity;
}
}
Then in my _LoginPartial.cshtml
(Under Views/Shared
Folders) I added @using.ProgramName.Models.Extensions
I then added the change to the folling line of code that was going to use the Users First name after Logging in :
@Html.ActionLink("Hello " + User.Identity.GetUserFirstname() + "!", "Index", "Manage", routeValues: null, htmlAttributes: new { title = "Manage" })
Perhaps this helps someone else down the line.
As of jQuery 1.7, the .live()
method is deprecated. Use .on()
to attach event handlers.
Example -
$( document ).on( events, selector, data, handler );

The above things are useful for any date parsing, not only now or today. It can be useful for any date parsing.
e.g.
my_date = "23-02-2018 00:00:00"
datetime.strptime(str(my_date),'%d-%m-%Y %H:%M:%S').strftime('%Y-%m-%d %H:%M:%S+00:00')
datetime.strptime(str(my_date),'%d-%m-%Y %H:%M:%S').strftime('%m')

This is my way i do comments (I think its secure):
<h1>Comment's:</h1>
<?php
$i = addslashes($_POST['a']);
$ip = addslashes($_POST['b']);
$a = addslashes($_POST['c']);
$b = addslashes($_POST['d']);
if(isset($i) & isset($ip) & isset($a) & isset($b))
{
$r = mysql_query("SELECT COUNT(*) FROM $db.ban WHERE ip=$ip"); //Check if banned
$r = mysql_fetch_array($r);
if(!$r[0]) //Phew, not banned
{
if(mysql_query("INSERT INTO $db.com VALUES ($a, $b, $ip, $i)"))
{
?>
<script type="text/javascript">
window.location="/index.php?id=".<?php echo $i; ?>;
</script>
<?php
}
else echo "Error, in mysql query";
}
else echo "Error, You are banned.";
}
$x = mysql_query("SELECT * FROM $db.com WHERE i=$i");
while($r = mysql_fetch_object($x) echo '<div class="c">'.$r->a.'<p>'.$row->b.'</p> </div>';
?>
<h1>Leave a comment, pl0x:</h1>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<input type="hidden" name="a" value="<?php $echo $_GET['id']; ?>" />

<input type="submit" />
</form>
This does it all in one page (This is only the comments section, some configuration is needed)

you can just do this:
string id = GridName.DataKeys[Convert.ToInt32(e.CommandArgument)].Value.ToString();
Im not sure if im out of the subject, but i found solution for me; You have a class based view, and you want to have a get parameter as a template tag:
class MyView(DetailView):
model = MyModel
def get_context_data(self, **kwargs):
ctx = super().get_context_data(**kwargs)
ctx['tag_name'] = self.request.GET.get('get_parameter_name', None)
return ctx
Then you make your get request /mysite/urlname?get_parameter_name='stuff
.
In your template, when you insert {{ tag_name }}
, you will have access to the get parameter value ('stuff'). If you have an url in your template that also needs this parameter, you can do
{% url 'my_url' %}?get_parameter_name={{ tag_name }}"
You will not have to modify your url configuration
It depends on wether the locatoin is detected by different DNS resolution from different locations, or by IP address that you are browsing from.
If its by DNS, you could just modify your hosts file to point at the server used in europe. Get your friend to ping the address, to see if its different from the one yours resolves to.
To browse from a different IP address:
You can rent a VPS server. You can use putty / SSH to act as a proxy. I use this from time to time to brows from the US using a VPS server I rent in the US.
Having an account on a remote host may or may not be enough. Sadly, my dreamhost account, even though I have ssh access, does not allow proxying.
I have been using NetworkImageView from the new Android Volley Library com.android.volley.toolbox.NetworkImageView

Bringing this back from the dead again. I got around a similar credentials problem by wrapping the .ps1 in a batch file and doing the Win7, Shift + r.Click RunAs. If you wanted to, you can also use PsExec thus:
psexec.exe /accepteula /h /u user /p pwd cmd /c "echo. | powershell.exe -File script.ps1"

In SQL Server Management Studio 2008 (R2) and newer, you can Right Click on the
DB -> Tasks -> Generate Scripts
Select the tables you want to DROP.
Select "Save to new query window".
Click on the Advanced button.
Set Script DROP and CREATE to Script DROP.
Set Script Foreign Keys to True.
Click OK.
Click Next -> Next -> Finish.
View the script and then Execute.
Another way is to use the object tag. This works on Chrome, IE, Firefox, Safari and Opera.
<object data="html/stuff_to_include.html">
Your browser doesn’t support the object tag.
</object>

For some time now I've been thinking about near-compile-time constraints, so this is a perfect opportunity to launch the concept.
The basic idea is that if you cannot do a check compile time, you should do it at the earliest possible point in time, which is basically the moment the application starts. If all checks are okay, the application will run; if a check fails, the application will fail instantly.
Behavior
The best possible outcome is that our program doesn't compile if the constraints are not met. Unfortunately that's not possible in the current C# implementation.
Next best thing is that the program crashes the moment it's started.
The last option is that the program will crash the moment the code is hit. This is the default behavior of .NET. For me, this is completely unacceptable.
Prerequirements
We need to have a constraint mechanism, so for the lack of anything better... let's use an attribute. The attribute will be present on top of a generic constraint to check if it matches our conditions. If it doesn't, we give an ugly error.
This enables us to do things like this in our code:
public class Clas<[IsInterface] T> where T : class
(I've kept the where T:class
here, because I always prefer compile-time checks to run-time checks)
So, that only leaves us with 1 problem, which is checking if all the types that we use match the constraint. How hard can it be?
Let's break it up
Generic types are always either on a class (/struct/interface) or on a method.
Triggering a constraint requires you to do one of the following things:
At this point, I would like to state that you should always avoid doing (4) in any program IMO. Regardless, these checks won't support it, since it would effectively mean solving the halting problem.
Case 1: using a type
Example:
public class TestClass : SomeClass<IMyInterface> { ... }
Example 2:
public class TestClass
{
SomeClass<IMyInterface> myMember; // or a property, method, etc.
}
Basically this involves scanning all types, inheritance, members, parameters, etc, etc, etc. If a type is a generic type and has a constraint, we check the constraint; if it's an array, we check the element type.
At this point I must add that this will break the fact that by default .NET loads types 'lazy'. By scanning all the types, we force the .NET runtime to load them all. For most programs this shouldn't be a problem; still, if you use static initializers in your code, you might encounter problems with this approach... That said, I wouldn't advice anyone to do this anyways (except for things like this :-), so it shouldn't give you a lot of problems.
Case 2: using a type in a method
Example:
void Test() {
new SomeClass<ISomeInterface>();
}
To check this we have only 1 option: decompile the class, check all member tokens that are used and if one of them is the generic type - check the arguments.
Case 3: Reflection, runtime generic construction
Example:
typeof(CtorTest<>).MakeGenericType(typeof(IMyInterface))
I suppose it's theoretically possible to check this with similar tricks as case (2), but the implementation of it is much harder (you need to check if MakeGenericType
is called in some code path). I won't go into details here...
Case 4: Reflection, runtime RTTI
Example:
Type t = Type.GetType("CtorTest`1[IMyInterface]");
This is the worst case scenario and as I explained before generally a bad idea IMHO. Either way, there's no practical way to figure this out using checks.
Testing the lot
Creating a program that tests case (1) and (2) will result in something like this:
[AttributeUsage(AttributeTargets.GenericParameter)]
public class IsInterface : ConstraintAttribute
{
public override bool Check(Type genericType)
{
return genericType.IsInterface;
}
public override string ToString()
{
return "Generic type is not an interface";
}
}
public abstract class ConstraintAttribute : Attribute
{
public ConstraintAttribute() {}
public abstract bool Check(Type generic);

To count the number of values larger than x in any numpy array you can use:
n = len(matrix[matrix > x])
The boolean indexing returns an array that contains only the elements where the condition (matrix > x) is met. Then len() counts these values.
You can use try-catch block to check for integer value
for eg:
User inputs in form of string
try
{
int num=Integer.parseInt("Some String Input");
}
catch(NumberFormatException e)
{
//If number is not integer,you wil get exception and exception message will be printed
System.out.println(e.getMessage());

for SQL server, the way to work around this is to first declare a temp table, insert value to that temp table, and then use MERGE
Like this:
declare @Source table
(
name varchar(30),
age decimal(23,0)
)
insert into @Source VALUES
('Helen', 24),
('Katrina', 21),
('Samia', 22),
('Hui Ling', 25),
('Yumie', 29);
MERGE beautiful AS Tg
using @source as Sc
on tg.namet=sc.name
when matched then update
set tg.age=sc.age
when not matched then
insert (name, age) VALUES
(SC.name, sc.age);
This was a real issue for me, and quite a sneaky problem to try and remedy...
The problem I had was that a module that was installed on my WiFi adapter was conflicting with the Microsoft Virtual Adapter (or whatever it's actually called).
To fix it:
R
ncpa.cpl
in to the box, and hit OK
.Properties
.The connection uses the following items:
. Look down the list for anything that seems out of the ordinary, and uncheck it. Hit OK
.netsh wlan start hostednetwork
command again.In my case my adapter was running a module called SoftEther Lightweight Network Protocol
, which I believe is used to help connect to VPN Gate VPN servers via the SoftEther software.
If literally nothing else works, then I'd suspect something similar to the problem I encountered, namely that a module on your network adapter is interfering with the hostednetwork aspect of your driver.
So,. I had this issue,. except I got [object object]
I'm sure you could do this with recursion but this worked for me:
Here is what I did in my console:
var object_that_is_not_shallow = $("all_obects_with_this_class_name");
var str = '';
object_that_is_not_shallow.map(function(_,e){
str += $(e).html();
});
copy(str);
Then paste into your editor.
In this tutorial is explained how to consume a web api with C#, in this example a console application is used, but you can also use another web api to consume of course.
http://www.asp.net/web-api/overview/web-api-clients/calling-a-web-api-from-a-net-client
You should have a look at the HttpClient
HttpClient client = new HttpClient();
client.BaseAddress = new Uri("http://localhost/yourwebapi");
Make sure your requests ask for the response in JSON using the Accept header like this:
client.DefaultRequestHeaders.Accept.Add(
new MediaTypeWithQualityHeaderValue("application/json"));
Now comes the part that differs from the tutorial, make sure you have the same objects as the other WEB API
, if not, then you have to map the objects to your own objects. ASP.NET
will convert the JSON
you receive to the object you want it to be.
HttpResponseMessage response = client.GetAsync("api/yourcustomobjects").Result;
if (response.IsSuccessStatusCode)
{
var yourcustomobjects = response.Content.ReadAsAsync<IEnumerable<YourCustomObject>>().Result;
foreach (var x in yourcustomobjects)
{
//Call your store method and pass in your own object
SaveCustomObjectToDB(x);
}
}
else
{
//Something has gone wrong, handle it here
}
please note that I use .Result
for the case of the example. You should consider using the async
await
pattern here.
Your second DELETE
query was nearly correct. Just be sure to put the table name (or an alias) between DELETE
and FROM
to specify which table you are deleting from. This is simpler than using a nested SELECT
statement like in the other answers.
DELETE tableA
FROM tableA
INNER JOIN tableB u on (u.qlabel = tableA.entityrole AND u.fieldnum = tableA.fieldnum)
WHERE (LENGTH(tableA.memotext) NOT IN (8,9,10)
OR tableA.memotext NOT LIKE '%/%/%')
AND (u.FldFormat = 'Date')
DELETE q
FROM tableA q
INNER JOIN tableB u on (u.qlabel = q.entityrole AND u.fieldnum = q.fieldnum)
WHERE (LENGTH(q.memotext) NOT IN (8,9,10)
OR q.memotext NOT LIKE '%/%/%')
AND (u.FldFormat = 'Date')
More examples here:
How to Delete using INNER JOIN with SQL Server?
To add to James's example, it seems you always have to create an intermediate when performing calculations on NA-containing data frames.
For instance, adding two columns (A and B) together from a data frame dfr
:
temp.df <- data.frame(dfr) # copy the original
temp.df[is.na(temp.df)] <- 0
dfr$C <- temp.df$A + temp.df$B # or any other calculation
remove('temp.df')
When I do this I throw away the intermediate afterwards with remove
/rm
.
Interesting blog post here:
http://geekswithblogs.net/cskardon/archive/2008/06/23/dispose-of-a-wpf-usercontrol-ish.aspx
It mentions subscribing to Dispatcher.ShutdownStarted to dispose of your resources.
You could just:
from random import randint
foo = ["a", "b", "c", "d", "e"]
print(foo[randint(0,4)])

Generic methods to compare a char at a position between 2 strings with ignore case.
public static boolean isEqualIngoreCase(char one, char two){
return Character.toLowerCase(one)==Character .toLowerCase(two);
}
public static boolean isEqualStringCharIgnoreCase(String one, String two, int position){
char oneChar = one.charAt(position);
char twoChar = two.charAt(position);
return isEqualIngoreCase(oneChar, twoChar);
}
Function call
boolean isFirstCharEqual = isEqualStringCharIgnoreCase("abc", "ABC", 0)
The literal answer to your question (to do exactly what you asked, changing only the wrapper, not the functions or the function calls) is simply to alter the line
func(args)
to read
func(*args)
This tells Python to take the list given (in this case, args
) and pass its contents to the function as positional arguments.
This trick works on both "sides" of the function call, so a function defined like this:
def func2(*args):
return sum(args)
would be able to accept as many positional arguments as you throw at it, and place them all into a list called args
.
I hope this helps to clarify things a little. Note that this is all possible with dicts/keyword arguments as well, using **
instead of *
.

exec is for statement and does not return anything. eval is for expression and returns value of expression.
expression means "something" while statement means "do something".
OK, just change your code to something like this:
<script>
function submit() {
return confirm('Do you really want to submit the form?');
}
</script>
<form onsubmit="return submit(this);">
<input type="image" src="xxx" border="0" name="submit" onclick="show_alert();"
alt="PayPal - The safer, easier way to pay online!" value="Submit">
</form>
Also this is the code in run, just I make it easier to see how it works, just run the code below to see the result:
function submitForm() {_x000D_
return confirm('Do you really want to submit the form?');_x000D_
}
_x000D_
<form onsubmit="return submitForm(this);">_x000D_
<input type="text" border="0" name="submit" />_x000D_
<button value="submit">submit</button>_x000D_
</form>

A good way to test if a string is a correct date is to use the command date:
if date -d "${DATE}" >/dev/null 2>&1
then
# do what you need to do with your date
else
echo "${DATE} incorrect date" >&2
exit 1
fi
from comment: one can use formatting
if [ "2017-01-14" == $(date -d "2017-01-14" '+%Y-%m-%d') ]
Change clean to
rm -f .lambda .lambda_t .activity .activity_t_lambda
I.e. don't prompt for remove; don't complain if file doesn't exist.
Simple function to check this:
function isArray(object)
{
return object.constructor === Array;

Try to edit your my.cf and comment the original sql_mode and add sql_mode = "".

On Swift 3. You can create an extension and add after your view class.
extension UITextField
{
func setBottomBorder(borderColor: UIColor)
{
self.borderStyle = UITextBorderStyle.none
self.backgroundColor = UIColor.clear
let width = 1.0
let borderLine = UIView()
borderLine.frame = CGRect(x: 0, y: Double(self.frame.height) - width, width: Double(self.frame.width), height: width)
borderLine.backgroundColor = borderColor
self.addSubview(borderLine)
}
}
This is the best and easiest code:
public class test
{
public static void main(String str[])
{
String jsonString = "{\"stat\": { \"sdr\": \"aa:bb:cc:dd:ee:ff\", \"rcv\": \"aa:bb:cc:dd:ee:ff\", \"time\": \"UTC in millis\", \"type\": 1, \"subt\": 1, \"argv\": [{\"type\": 1, \"val\":\"stackoverflow\"}]}}";
JSONObject jsonObject = new JSONObject(jsonString);
JSONObject newJSON = jsonObject.getJSONObject("stat");
System.out.println(newJSON.toString());
jsonObject = new JSONObject(newJSON.toString());
System.out.println(jsonObject.getString("rcv"));
System.out.println(jsonObject.getJSONArray("argv"));
}
}
The library definition of the json files are given here. And it is not same libraries as posted here, i.e. posted by you. What you had posted was simple json library I have used this library.
You can download the zip. And then create a package
in your project with org.json as name. and paste all the downloaded codes there, and have fun.
I feel this to be the best and the most easiest JSON Decoding.
You have to indent the docstring after the function definition there (line 3, 4):
def print_lol(the_list):
"""this doesn't works"""
print 'Ain't happening'
Indented:
def print_lol(the_list):
"""this works!"""
print 'Aaaand it's happening'
Or you can use #
to comment instead:
def print_lol(the_list):
#this works, too!
print 'Hohoho'
Also, you can see PEP 257 about docstrings.
Hope this helps!
You will not be able to do that. You can download apps again to the same userid account on different devices, but you cannot transfer those licenses to other userids.
There is no way to do this programatically - I don't think you can do that practically (except for trying to call customer support at the Play Store).
The usual way to set the line color in matplotlib is to specify it in the plot command. This can either be done by a string after the data, e.g. "r-"
for a red line, or by explicitely stating the color
argument.
import matplotlib.pyplot as plt
plt.plot([1,2,3], [2,3,1], "r-") # red line
plt.plot([1,2,3], [5,5,3], color="blue") # blue line
plt.show()
See also the plot command's documentation.
In case you already have a line with a certain color, you can change that with the lines2D.set_color()
method.
line, = plt.plot([1,2,3], [4,5,3], color="blue")
line.set_color("black")
import matplotlib.pyplot as plt
import pandas as pd
df = pd.DataFrame({ "x" : [1,2,3,5], "y" : [3,5,2,6]})
df.plot("x", "y", color="r") #plot red line
plt.show()
If you want to change this color later on, you can do so by
plt.gca().get_lines()[0].set_color("black")
This will get you the first (possibly the only) line of the current active axes.
In case you have more axes in the plot, you could loop through them
for ax in plt.gcf().axes:
ax.get_lines()[0].set_color("black")
and if you have more lines you can loop over them as well.
Can't bind to 'formGroup' since it isn't a known property of 'form'
means that you try to bind a property using angular ([prop]
) but angular cant find anything he knows for that element (in this case form
).
this can happen by not using the right module (missing an import somewhere in the way) and sometimes just cause a typo like:
[formsGroup]
, with s
after form
try $conn = mysql_connect("localhost", "root")
or $conn = mysql_connect("localhost", "root", "")
In a conda
environment, this is what solved my problem (I was missing cudart64-100.dll
:
Downloaded it from dll-files.com/CUDART64_100.DLL
Put it in my conda environment at
C:\Users\<user>\Anaconda3\envs\<env name>\Library\bin
That's all it took! You can double check if it's working:
import tensorflow as tf
tf.config.experimental.list_physical_devices('GPU')
One way you can do it, is to get the slaves list from the frame that needs to be cleared and destroy or "hide" them according to your needs. To get a clear frame you can do it like this:
from tkinter import *
root = Tk()
def clear():
list = root.grid_slaves()
for l in list:
l.destroy()
Label(root,text='Hello World!').grid(row=0)
Button(root,text='Clear',command=clear).grid(row=1)
root.mainloop()
You should call grid_slaves()
, pack_slaves()
or slaves()
depending on the method you used to add the widget to the frame.
The convert
function with the format specifier 120 will give you the format "yyyy-MM-dd HH:mm:ss", so you just have to limit the length to 10 to get only the date part:
convert(varchar(10), theDate, 120)
However, formatting dates is generally better to do in the presentation layer rather than in the database or business layer. If you return the date formatted from the database, then the client code has to parse it to a date again if it needs to do any calculations on it.
Example in C#:
theDate.ToString("yyyy-MM-dd")
BT version 2.0 or less - You should be able to pair/bond using a standard PIN code, entered programmatically e.g. 1234 or 0000. This is not very secure but many BT devices do this.
BT version 2.1 or greater - Mode 4 Secure Simple Pairing "just works" model can be used. It uses elliptical encryption (whatever that is) and is very secure but is open to Man In The Middle attacks. Compared to the old '0000' pin code approach it is light years ahead. This doesn't require any user input.
This is according to the Bluetooth specs but what you can use depends on what verson of the Bluetooth standard your stack supports and what API you have.
Those who are getting same error in Android 3.0.1,can resolve it by simply update the versions of compileSdkVersion and targetSdkVersion to 27 and also Implement com.android.support:appcompat-v7:27.1.1' in dependencies.
Radio buttons have another attribute - checked or unchecked. You need to set which button was selected by the user, so you have to write PHP code inside the HTML with these values - checked or unchecked. Here's one way to do it:
The PHP code:
<?PHP
$male_status = 'unchecked';
$female_status = 'unchecked';
if (isset($_POST['Submit1'])) {
$selected_radio = $_POST['gender'];
if ($selected_radio == 'male') {
$male_status = 'checked';
}else if ($selected_radio == 'female') {
$female_status = 'checked';
}
}
?>
The HTML FORM code:
<FORM name ="form1" method ="post" action ="radioButton.php">
<Input type = 'Radio' Name ='gender' value= 'male'
<?PHP print $male_status; ?>
>Male
<Input type = 'Radio' Name ='gender' value= 'female'
<?PHP print $female_status; ?>
>Female
<P>
<Input type = "Submit" Name = "Submit1" VALUE = "Select a Radio Button">
</FORM>
In Bootstrap 3, .form-control
(the class you give your inputs) has a width of 100%, which allows you to wrap them into col-lg-X divs for arrangement. Example from the docs:
<div class="row">
<div class="col-lg-2">
<input type="text" class="form-control" placeholder=".col-lg-2">
</div>
<div class="col-lg-3">
<input type="text" class="form-control" placeholder=".col-lg-3">
</div>
<div class="col-lg-4">
<input type="text" class="form-control" placeholder=".col-lg-4">
</div>
</div>
See under Column sizing.
It's a bit different than in Bootstrap 2.3.2, but you get used to it quickly.
Using the Intl object (or via toLocaleString) is somewhat problematic, but it can be made precise using the formatToParts method and manually putting the parts in order, e.g.
function formatDate(date = new Date()) {_x000D_
let {day, month, year} = new Intl.DateTimeFormat('en', {_x000D_
day:'2-digit',_x000D_
month: 'short',_x000D_
year: 'numeric'_x000D_
}).formatToParts(date).reduce((acc, part) => {_x000D_
if (part.type != 'literal') {_x000D_
acc[part.type] = part.value;_x000D_
}_x000D_
return acc;_x000D_
}, Object.create(null));_x000D_
return `${day}-${month}-${year}`;_x000D_
}_x000D_
_x000D_
console.log(formatDate());
_x000D_
Using reduce on the array returned by formatToParts trims out the literals and creates an object with named properties that is then assigned to variables and finally formatted.
This function doesn't always work nicely for languages other than English though as the short month name may have punctuation.
Now on the Api 30 level , it should be done like this
final WindowMetrics metrics = windowManager.getCurrentWindowMetrics();
// Gets all excluding insets
final WindowInsets windowInsets = metrics.getWindowInsets();
Insets insets = windowInsets.getInsetsIgnoreVisibility(WindowInsets.Type.navigationBars()
| WindowInsets.Type.displayCutout());
int insetsWidth = insets.right + insets.left;
int insetsHeight = insets.top + insets.bottom;
// Legacy size that Display#getSize reports
final Rect bounds = metrics.getBounds();
final Size legacySize = new Size(bounds.width() - insetsWidth,
bounds.height() - insetsHeight);
you have to rename each column
SELECT col1 as MyCol1,
col2 as MyCol2,
.......
FROM `foobar`
for i=1,#target do
game.Players.target[i].Character:BreakJoints()
end
Is incorrect, if "target" contains "FakeNameHereSoNoStalkers" then the run code would be:
game.Players.target.1.Character:BreakJoints()
Which is completely incorrect.
c = game.Players:GetChildren()
Never use "Players:GetChildren()", it is not guaranteed to return only players.
Instead use:
c = Game.Players:GetPlayers()
if msg:lower()=="me" then
table.insert(people, source)
return people
Here you add the player's name in the list "people", where you in the other places adds the player object.
Fixed code:
local Admins = {"FakeNameHereSoNoStalkers"}
function Kill(Players)
for i,Player in ipairs(Players) do
if Player.Character then
Player.Character:BreakJoints()
end
end
end
function IsAdmin(Player)
for i,AdminName in ipairs(Admins) do
if Player.Name:lower() == AdminName:lower() then return true end
end
return false
end
function GetPlayers(Player,Msg)
local Targets = {}
local Players = Game.Players:GetPlayers()
if Msg:lower() == "me" then
Targets = { Player }
elseif Msg:lower() == "all" then
Targets = Players
elseif Msg:lower() == "others" then
for i,Plr in ipairs(Players) do
if Plr ~= Player then
table.insert(Targets,Plr)
end
end
else
for i,Plr in ipairs(Players) do
if Plr.Name:lower():sub(1,Msg:len()) == Msg then
table.insert(Targets,Plr)
end
end
end
return Targets
end
Game.Players.PlayerAdded:connect(function(Player)
if IsAdmin(Player) then
Player.Chatted:connect(function(Msg)
if Msg:lower():sub(1,6) == ":kill " then
Kill(GetPlayers(Player,Msg:sub(7)))
end
end)
end
end)
Simply you can use the following code:
$arr=explode('sep1',str_replace(array('sep2','sep3','sep4'),'sep1',$mystring));
For big array, is better to concatenate without array_merge, for avoid a memory copy.
$array1 = array_fill(0,50000,'aa');
$array2 = array_fill(0,100,'bb');
// Test 1 (array_merge)
$start = microtime(true);
$r1 = array_merge($array1, $array2);
echo sprintf("Test 1: %.06f\n", microtime(true) - $start);
// Test2 (avoid copy)
$start = microtime(true);
foreach ($array2 as $v) {
$array1[] = $v;
}
echo sprintf("Test 2: %.06f\n", microtime(true) - $start);
// Test 1: 0.004963
// Test 2: 0.000038
The only way to do it is by checking the value of the isCancelled() method and stopping playback when it returns true.
If you have more than one version of python installed, run the respective pip command.
For example for python3.6 run the following
pip3.6 install beautifulsoup4
To check the available command/version of pip and python on Mac run
ls /usr/local/bin
I think this is related to the newer version of spring boot plus using spring data JPA just replace @Bean annotation above public LocalContainerEntityManagerFactoryBean entityManagerFactory() to @Bean(name="entityManagerFactory")
Determining the name of bean should solve the issue
I solved this problem very easily after finding out this happens when you aren't outputting a proper JSON object, I simply used the echo json_encode($arrayName);
instead of print_r($arrayName);
With my php api.
Every programming language or at least most programming languages should have their own version of the json_encode()
and json_decode()
functions.
this did it for me. you can vary the options for the output format to Base64.Default whatsoever.
// encode base64 from image
ByteArrayOutputStream baos = new ByteArrayOutputStream();
imageBitmap.compress(Bitmap.CompressFormat.PNG, 100, baos);
byte[] b = baos.toByteArray();
encodedString = Base64.encodeToString(b, Base64.URL_SAFE | Base64.NO_WRAP);
Framebuffer seems the way to go, it will not always contain 2+ frames like mentioned by Ryan Conrad. In my case it contained only one. I guess it depends on the frame/display size.
I tried to read the framebuffer continuously but it seems to return for a fixed amount of bytes read. In my case that is (3 410 432) bytes, which is enough to store a display frame of 854*480 RGBA (3 279 360 bytes). Yes, the frame in binary outputed from fb0 is RGBA in my device. This will most likely depend from device to device. This will be important for you to decode it =)
In my device /dev/graphics/fb0 permissions are so that only root and users from group graphics can read the fb0. graphics is a restricted group so you will probably only access fb0 with a rooted phone using su command.
Android apps have the user id (uid) app_## and group id (guid) app_## .
adb shell has uid shell and guid shell, which has much more permissions than an app. You can actually check those permissions at /system/permissions/platform.xml
This means you will be able to read fb0 in the adb shell without root but you will not read it within the app without root.
Also, giving READ_FRAME_BUFFER and/or ACCESS_SURFACE_FLINGER permissions on AndroidManifest.xml will do nothing for a regular app because these will only work for 'signature' apps.

I believe you need subexpressions. If I remember right you can use the normal ()
brackets for subexpressions.
This part is From grep manual:
Back References and Subexpressions
The back-reference \n, where n is a single digit, matches the substring
previously matched by the nth parenthesized subexpression of the
regular expression.
Do something like ^[^(abc)]
should do the trick.
It is highly unlikely that adding NameVirtualHost *:443
is the right solution, because there are a limited number of situations in which it is possible to support name-based virtual hosts over SSL. Read this and this for some details (there may be better docs out there; these were just ones I found that discuss the issue in detail).
If you're running a relatively stock Apache configuration, you probably have this somewhere:
<VirtualHost _default_:443>
Your best bet is to either:
VirtualHost
container, or VirtualHost
block and create a new one. Don't forget to include all the relevant SSL options.Using Moment library, see their website -> https://momentjs.com/timezone/docs/#/using-timezones/converting-to-zone/
i notice they also user their own library in their website, so you can have a try using the browser console before installing it
moment().tz(String);
The moment#tz mutator will change the time zone and update the offset.
moment("2013-11-18").tz("America/Toronto").format('Z'); // -05:00
moment("2013-11-18").tz("Europe/Berlin").format('Z'); // +01:00
This information is used consistently in other operations, like calculating the start of the day.
var m = moment.tz("2013-11-18 11:55", "America/Toronto");
m.format(); // 2013-11-18T11:55:00-05:00
m.startOf("day").format(); // 2013-11-18T00:00:00-05:00
m.tz("Europe/Berlin").format(); // 2013-11-18T06:00:00+01:00
m.startOf("day").format(); // 2013-11-18T00:00:00+01:00
Without an argument, moment#tz returns:
the time zone name assigned to the moment instance or
undefined if a time zone has not been set.
var m = moment.tz("2013-11-18 11:55", "America/Toronto");
m.tz(); // America/Toronto
var m = moment.tz("2013-11-18 11:55");
m.tz() === undefined; // true
I warmly recommend this snippet to ensure, accidentally left code pieces don't fail on clients browsers:
/* neutralize absence of firebug */
if ((typeof console) !== 'object' || (typeof console.info) !== 'function') {
window.console = {};
window.console.info = window.console.log = window.console.warn = function(msg) {};
window.console.trace = window.console.error = window.console.assert = function(msg) {};
}
rather than defining an empty function, this snippet is also a good starting point for rolling your own console surrogate if needed, i.e. dumping those infos into a .debug Container, show alerts (could get plenty) or such...
If you do use firefox+firebug, console.dir()
is best for dumping array output, see here.
You could use the substr
function please check following example,
$string1 = "tarunmodi";
$first4 = substr($string1, 4);
echo $first4;
Output: nmodi
You should be able to just run select * from information_schema.tables
to get a listing of every table being managed by Postgres for a particular database.
You can also add a where table_schema = 'information_schema'
to see just the tables in the information schema.
If you run a the module task with android plugin 1.2.3 in module directory , the problem appears. Try this:
../gradlew -b ../build.gradle -c ../settings.gradle :module:xxx
Answered here quite elegantly using attached behaviors, my preferred method for almost anything.
Here's a slightly more flexible approach using the match
method. With this, you can extract more than one string:
s = "<ants> <pants>"
matchdata = s.match(/<([^>]*)> <([^>]*)>/)
# Use 'captures' to get an array of the captures
matchdata.captures # ["ants","pants"]
# Or use raw indices
matchdata[0] # whole regex match: "<ants> <pants>"
matchdata[1] # first capture: "ants"
matchdata[2] # second capture: "pants"
In my case, I don't got tmp folder setting up right. What I end up with these steps:
1. cd /
2. ln -s private/tmp /tmp
If you want to rotate 45 degrees, you can use the CSS transform property:
.fa-rotate-45 {
-ms-transform:rotate(45deg); /* Internet Explorer 9 */
-webkit-transform:rotate(45deg); /* Chrome, Safari, Opera */
transform:rotate(45deg); /* Standard syntax */
}
I've found out that somethimes one ScrollView regains focus and the other loses focus. You can prevent that, by only granting one of the scrollView focus:
scrollView1= (ScrollView) findViewById(R.id.scrollscroll);
scrollView1.setAdapter(adapter);
scrollView1.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
scrollView1.getParent().requestDisallowInterceptTouchEvent(true);
return false;
}
});
Look the answer to my previous question here
c:\> for %i in (java.exe) do @echo. %~$PATH:i
C:\WINDOWS\system32\java.exe
You can also check contents of *.tag.gz file using pigz
(parallel gzip) to speedup the archive check:
pigz -cvdp number_of_threads /[...]path[...]/archive_name.tar.gz | tar -tv > /dev/null
Try following these if these might help:
Since your installation works on the terminal you installed, all the exports
you did, work on the current bash and its child process
. but is not spawned to new terminals
.
env
variables are lost if the session is closed; using .bash_profile
, you can make it available in all sessions, since when a bash
session starts, it 'runs' its .bashrc and .bash_profile
Now follow these steps and see if it helps:
type env | grep M2_HOME
on the terminal that is working. This should give something like
M2_HOME=/usr/local/apache-maven/apache-maven-3.1.1
typing env | grep JAVA_HOME
should give like this:
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home
Now you have the PATH for M2_HOME
and JAVA_HOME
.
If you just do ls /usr/local/apache-maven/apache-maven-3.1.1/bin
, you will see mvn
binary there.
All you have to do now is to point to this location everytime using PATH. since bash
searches in all the directory path mentioned in PATH
, it will find mvn
.
now open .bash_profile
, if you dont have one just create one
vi ~/.bash_profile
Add the following:
#set JAVA_HOME
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.7.0_40.jdk/Contents/Home
export JAVA_HOME
M2_HOME=/usr/local/apache-maven/apache-maven-3.1.1
export M2_HOME
PATH=$PATH:$JAVA_HOME/bin:$M2_HOME/bin
export PATH
save the file and type source ~/.bash_profile
. This steps executes the commands in the .bash_profile
file and you are good to go now.
open a new terminal and type mvn
that should work.
For MySQL Workbench 6.1: in the home window click on the server instance(connection)/ or create a new one. In the thus opened 'connection' tab click on 'server' -> 'data import'. The rest of the steps remain as in Vishy's answer.
If you are still inside the vi editor, you might be in a different mode from the one you want. Hit ESC a couple of times (until it rings or flashes) and then "i" to enter INSERT mode or "a" to enter APPEND mode (they are the same, just start before or after current character).
If you are back at the command prompt, make sure you can locate the file, then navigate to that directory and perform the mentioned "vi helloWorld.txt". Once you are in the editor, you'll need to check the vi reference to know how to perform the editions you want (you may want to google "vi reference" or "vi cheat sheet").
Once the edition is done, hit ESC again, then type :wq
to save your work or :q!
to quit without saving.
For quick reference, here you have a text-based cheat sheet.
Instead of relying only on <c:out />
, an antixss library should also be used, which will not only encode but also sanitize malicious script in input. One of the best library available is OWASP Antisamy, it's highly flexible and can be configured(using xml policy files) as per requirement.
For e.g. if an application supports only text input then most generic policy file provided by OWASP can be used which sanitizes and removes most of the html tags. Similarly if application support html editors(such as tinymce) which need all kind of html tags, a more flexible policy can be use such as ebay policy file
You need to enclose your try-catch
inside a while
loop like this: -
int count = 0;
int maxTries = 3;
while(true) {
try {
// Some Code
// break out of loop, or return, on success
} catch (SomeException e) {
// handle exception
if (++count == maxTries) throw e;
}
}
I have taken count
and maxTries
to avoid running into an infinite loop, in case the exception keeps on occurring in your try block
.
For completeness, guava also has a handy utility for this
ByteStreams.copy(input, output);
Just use the --jars
parameter. Spark will share those jars (comma-separated) with the executors.
Try this
$("#message span").text("hello world!");
function Errormessage(txt) {
var elem = $("#message");
elem.fadeIn("slow");
// find the span inside the div and assign a text
elem.children("span").text("your text");
elem.children("a.close-notify").click(function() {
elem.fadeOut("slow");
});
}
In Java size of array is fixed , but you can add elements dynamically to a fixed sized array using its index and for loop. Please find example below.
package simplejava;
import java.util.Arrays;
/**
*
* @author sashant
*/
public class SimpleJava {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
try{
String[] transactions;
transactions = new String[10];
for(int i = 0; i < transactions.length; i++){
transactions[i] = "transaction - "+Integer.toString(i);
}
System.out.println(Arrays.toString(transactions));
}catch(Exception exc){
System.out.println(exc.getMessage());
System.out.println(Arrays.toString(exc.getStackTrace()));
}
}
}
JavaScript validation is not secure as anybody can change what your script does in the browser. Using it for enhancing the visual experience is ok though.
var textBox = document.getElementById("myTextBox");
var textLength = textBox.value.length;
if(textLength > 5)
{
//red
textBox.style.backgroundColor = "#FF0000";
}
else
{
//green
textBox.style.backgroundColor = "#00FF00";
}
Make sure SQL Server is enabled for TCP/IP (someone may have disabled it)?
This will also help you to check/verify the port number the SQL instance is using (in case someone changed it from the default of port 1433).
Obviously port 1433 (or whatever port SQL is listening on) needs to be unblocked by any firewalls between your machine and the box SQL is running on.
To check SQL's network configuration (requires SQL Server Client Tools installed): Start -> Programs -> SQL Server 200x -> Configuration Tools -> SQL Server Configuration Manager
Connect to the machine you need then expand the Tree Item (LHS) "SQL Server Network Configuration", then pick instance. You should have four options - Shared Memory, Named Pipes, TCP/IP and VIA. You can check that TCP/IP is enabled in the RHS window.
If you double click TCP/IP and hit the "Advanced" tab, you can also view the Port number.
Other thoughts.. Are you using SQL Authentication or Windows (Domain) authentication?
If SQL Authentication (which I assume you are using given you said username and password), are you sure the SQL instance you're connecting to has mixed mode authentication enabled? If not, you have to connect as Administrator and change the default security settings to allow SQL authentication.
If Windows Authentication, could your network be using Kerberos potentially? One would think the VPN credentials would be used for the handshake. I'd check your account has appropriate login rights.
This is what I did to get it to work.
I am using pythonbrew(which is using pip) with python 2.7.5 installed.
I first did what Zubair(above) said and ran this command:
sudo apt-get install libsqlite3-dev
Then I ran this command:
pip install pysqlite
This fixed the database problem and I got confirmation of this when I ran:
python manager.py syncdb
Nice solutions, but I wonder why nobody is giving the solution for windows.
If you are using windows you just have to "Run as Administrator" the cmd.
One command to convert date time to Unix format and then to string
DateTime.strptime(Time.now.utc.to_i.to_s,'%s').strftime("%d %m %y")
Time.now.utc.to_i #Converts time from Unix format
DateTime.strptime(Time.now.utc.to_i.to_s,'%s') #Converts date and time from unix format to DateTime
finally strftime is used to format date
Example:
irb(main):034:0> DateTime.strptime("1410321600",'%s').strftime("%d %m %y")
"10 09 14"
Getting python to read a single character from the terminal in an unbuffered manner is a little bit tricky, but here's a recipe that'll do it:
For people using private GitLabs, here's a snippet that may help: https://gist.github.com/MicahParks/1ba2b19c39d1e5fccc3e892837b10e21
Also pasted below:
The go
command line tool needs to be able to fetch dependencies from your private GitLab, but authenticaiton is required.
This assumes your private GitLab is hosted at privategitlab.company.com
.
The following environment variables are recommended:
export GO111MODULE=on
export GOPRIVATE=privategitlab.company.com
The above lines might fit best in your shell startup, like a ~/.bashrc
.
GO111MODULE=on
tells Golang command line tools you are using modules. I have not tested this with projects not using
Golang modules on a private GitLab.
GOPRIVATE=privategitlab.company.com
tells Golang command line tools to not use public internet resources for the hostnames
listed (like the public module proxy).
To future proof these instructions, please follow this guide from the GitLab docs.
I know that the read_api
scope is required for Golang command line tools to work, and I may suspect read_repository
as
well, but have not confirmed this.
~/.netrc
In order for the Golang command line tools to authenticate to GitLab, a ~/.netrc
file is best to use.
To create the file if it does not exist, run the following commands:
touch ~/.netrc
chmod 600 ~/.netrc
Now edit the contents of the file to match the following:
machine privategitlab.company.com login USERNAME_HERE password TOKEN_HERE
Where USERNAME_HERE
is replaced with your GitLab username and TOKEN_HERE
is replaced with the access token aquired in the
previous section.
Do not set up a global git configuration with something along the lines of this:
git config --global url."[email protected]:".insteadOf "https://privategitlab.company.com"
I beleive at the time of writing this, the SSH git is not fully supported by Golang command line tools and this may cause
conflicts with the ~/.netrc
.
For regular use of the git
tool, not the Golang command line tools, it's convient to have a ~/.ssh/config
file set up.
In order to do this, run the following commands:
mkdir ~/.ssh
chmod 700 ~/.ssh
touch ~/.ssh/config
chmod 600 ~/.ssh/config
Please note the permissions on the files and directory above are essentail for SSH to work in it's default configuration on most Linux systems.
Then, edit the ~/.ssh/config
file to match the following:
Host privategitlab.company.com
Hostname privategitlab.company.com
User USERNAME_HERE
IdentityFile ~/.ssh/id_rsa
Please note the spacing in the above file matters and will invalidate the file if it is incorrect.
Where USERNAME_HERE
is your GitLab username and ~/.ssh/id_rsa
is the path to your SSH private key in your file system.
You've already uploaded its public key to GitLab. Here are some instructions.
Just Change the Distribution url at gradle-wrapper.properties
Place it : https://services.gradle.org/distributions/gradle-4.10.1-all.zip
From the update 2 and after narrowing down the problem scope, we can easily find that there is a brace missing at the end of the function addWord
. The compiler will never explicitly identify such a syntax error. instead, it will assume that the missing function definition located in some other object file. The linker will complain about it and hence directly will be categorized under one of the broad the error phrases which is identifier is undefined
. Reasonably, because with the current syntax the next function definition (in this case is ac_search
) will be included under the addWord
scope. Hence, it is not a global function anymore. And that is why compiler will not see this function outside addWord
and will throw this error message stating that there is no such a function. A very good elaboration about the compiler and the linker can be found in this article
ECMAScript 2015 introduced destructuring assignment which works pretty nice:
[a, b] = [1, 2]
a
will equal 1
and b
will equal 2
.
This is a prompt to create a bunch of object, such as sp_help_diagram (?), that do not exist.
This should have nothing to do with the owner of the db.
You can also try setting the system variable path to the location of your nuget exe and restarting VS.
PATH
variable and add the location of your nuget.exe (for me this is: C:\Program Files (x86)\NuGet\Visual Studio 2013
)I would have posted this as a comment to your answer @done_merson but I didn't have the required reputation to do that.
yes_js_login = function() {
// Your code here
return false;
}
If you return false it should prevent the default action (going to the href).
Edit: Sorry that doesn't seem to work, you can do the following instead:
<a href="http://example.com/no-js-login" onclick="yes_js_login(); return false;">Link</a>
The following command will (1) compare the file of the correct branch, to master (2) interactively ask you which modifications to apply.
git checkout --patch master
Thanks for the replies.
What I did was,
1. I install meinberg ntp software application on windows 7 pc. (softros ntp server is also possible.)
2. change raspberry pi ntp.conf file (for auto update date and time)
server xxx.xxx.xxx.xxx iburst
server 1.debian.pool.ntp.org iburst
server 2.debian.pool.ntp.org iburst
server 3.debian.pool.ntp.org iburst
3. If you want to make sure that date and time update at startup run this python script in rpi,
import os
try:
client = ntplib.NTPClient()
response = client.request('xxx.xxx.xxx.xxx', version=4)
print "===================================="
print "Offset : "+str(response.offset)
print "Version : "+str(response.version)
print "Date Time : "+str(ctime(response.tx_time))
print "Leap : "+str(ntplib.leap_to_text(response.leap))
print "Root Delay : "+str(response.root_delay)
print "Ref Id : "+str(ntplib.ref_id_to_text(response.ref_id))
os.system("sudo date -s '"+str(ctime(response.tx_time))+"'")
print "===================================="
except:
os.system("sudo date")
print "NTP Server Down Date Time NOT Set At The Startup"
pass
I found more info in raspberry pi forum.
if you want to change only the colour of the flag on hover

Simple to me is like this:
$Time = Get-Date -Format "yyyy-MM-dd HH:mm K"
$Description = "Done on time"
"$Time,$Description"|Add-Content -Path $File # Keep no space between content variables
If you have a lot of columns, then create a variable like $NewRow
like:
$Time = Get-Date -Format "yyyy-MM-dd HH:mm K"
$Description = "Done on time"
$NewRow = "$Time,$Description" # No space between variables, just use comma(,).
$NewRow | Add-Content -Path $File # Keep no space between content variables
Please note the difference between Set-Content
(overwrites the existing contents) and Add-Content
(appends to the existing contents) of the file.
Basic Authentication use base 64 Encoding for generating cryptographic string which contains the information of username and password.
Digest Access Authentication uses the hashing methodologies to generate the cryptographic result
In getUserById
you shouldn't create a new object (user1) which isn't used. Just assign it to the already (but null) initialized user
. Otherwise Hibernate.initialize(user);
is actually Hibernate.initialize(null);
Here's the new getUserById
(I haven't tested this ;)):
public User getUserById(Long user_id) {
Session session = null;
Object user = null;
try {
session = HibernateUtil.getSessionFactory().openSession();
user = (User)session.load(User.class, user_id);
Hibernate.initialize(user);
} catch (Exception e) {
e.printStackTrace();
} finally {
if (session != null && session.isOpen()) {
session.close();
}
}
return user;
}
I solved it by adding this to the /etc/profile - system wide (or to user local .profile, or _.bash_profile_):
# SSH-AGENT
#!/usr/bin/env bash
SERVICE='ssh-agent'
WHOAMI=`who am i |awk '{print $1}'`
if pgrep -u $WHOAMI $SERVICE >/dev/null
then
echo $SERVICE running.
else
echo $SERVICE not running.
echo starting
ssh-agent > ~/.ssh/agent_env
fi
. ~/.ssh/agent_env
This starts a new ssh-agent if not running for the current user, or re-sets the ssh-agent env parameter if running.
At the time of writing in 2013, this was one way to do it. Composer has added support for better ways: See @igorw 's answer
DO YOU HAVE A REPOSITORY?
Git, Mercurial and SVN is supported by Composer.
DO YOU HAVE WRITE ACCESS TO THE REPOSITORY?
Yes?
DOES THE REPOSITORY HAVE A composer.json
FILE
If you have a repository you can write to: Add a composer.json
file, or fix the existing one, and DON'T use the solution below.
Go to @igorw 's answer
ONLY USE THIS IF YOU DON'T HAVE A REPOSITORY
OR IF THE REPOSITORY DOES NOT HAVE A composer.json
AND YOU CANNOT ADD IT
This will override everything that Composer may be able to read from the original repository's composer.json
, including the dependencies of the package and the autoloading.
Using the package
type will transfer the burden of correctly defining everything onto you. The easier way is to have a composer.json
file in the repository, and just use it.
This solution really only is for the rare cases where you have an abandoned ZIP download that you cannot alter, or a repository you can only read, but it isn't maintained anymore.

If the .project
and .classpath
are already committed, then they need to be removed from the index (but not the disk)
git rm --cached .project
git rm --cached .classpath
Then the .gitignore
would work (and that file can be added and shared through clones).
For instance, this gitignore.io/api/eclipse
file will then work, which does include:
# Eclipse Core
.project
# JDT-specific (Eclipse Java Development Tools)
.classpath
Note that you could use a "Template Directory" when cloning (make sure your users have an environment variable $GIT_TEMPLATE_DIR
set to a shared folder accessible by all).
That template folder can contain an info/exclude
file, with ignore rules that you want enforced for all repos, including the new ones (git init
) that any user would use.
When you change the index, you need to commit the change and push it.
Then the file is removed from the repository. So the newbies cannot checkout the files.classpath
and.project
from the repo.
Plots in a single line are really simple, and can help one see patterns of highs and lows.

You cannot expect to parse a date with a SimpleDateFormat that is set up with a different format.
To parse your "Thu Jun 18 20:56:02 EDT 2009" date string you need a SimpleDateFormat like this (roughly):
SimpleDateFormat parser=new SimpleDateFormat("EEE MMM d HH:mm:ss zzz yyyy");
Use this to parse the string into a Date, and then your other SimpleDateFormat to turn that Date into the format you want.
String input = "Thu Jun 18 20:56:02 EDT 2009";
SimpleDateFormat parser = new SimpleDateFormat("EEE MMM d HH:mm:ss zzz yyyy");
Date date = parser.parse(input);
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");

Guide to Git on Windows and GitHub using SSH to push/pull: An Illustrated Guide to Git on Windows
There is an excellent answer provided by @Adem Öztas, for use with httplib
and urllib2
. For requests
, if the question is strictly about resource existence, then the answer can be improved upon in the case of large resource existence.
The previous answer for requests
suggested something like the following:
def uri_exists_get(uri: str) -> bool:
try:
response = requests.get(uri)
try:
response.raise_for_status()
return True
except requests.exceptions.HTTPError:
return False
except requests.exceptions.ConnectionError:
return False
requests.get
attempts to pull the entire resource at once, so for large media files, the above snippet would attempt to pull the entire media into memory. To solve this, we can stream the response.
def uri_exists_stream(uri: str) -> bool:
try:
with requests.get(uri, stream=True) as response:
try:
response.raise_for_status()
return True
except requests.exceptions.HTTPError:
return False
except requests.exceptions.ConnectionError:
return False
I ran the above snippets with timers attached against two web resources:
1) http://bbb3d.renderfarming.net/download.html, a very light html page
2) http://distribution.bbb3d.renderfarming.net/video/mp4/bbb_sunflower_1080p_30fps_normal.mp4, a decently sized video file
Timing results below:
uri_exists_get("http://bbb3d.renderfarming.net/download.html")
# Completed in: 0:00:00.611239
uri_exists_stream("http://bbb3d.renderfarming.net/download.html")
# Completed in: 0:00:00.000007
uri_exists_get("http://distribution.bbb3d.renderfarming.net/video/mp4/bbb_sunflower_1080p_30fps_normal.mp4")
# Completed in: 0:01:12.813224
uri_exists_stream("http://distribution.bbb3d.renderfarming.net/video/mp4/bbb_sunflower_1080p_30fps_normal.mp4")
# Completed in: 0:00:00.000007
As a last note: this function also works in the case that the resource host doesn't exist. For example "http://abcdefghblahblah.com/test.mp4"
will return False
.
I think this solves
using System.Linq;
(datagridview1.DataSource as DataTable).AsEnumerable().Sum(c => c.Field<double>("valor"))
if A:
will prove false if A is 0, False, empty string, empty list or None, which can lead to undesired results.
char ch='"';
System.out.println(ch + "String" + ch);
Or
System.out.println('"' + "ASHISH" + '"');
list()
is inherently slower than []
, because
there is symbol lookup (no way for python to know in advance if you did not just redefine list to be something else!),
there is function invocation,
then it has to check if there was iterable argument passed (so it can create list with elements from it) ps. none in our case but there is "if" check
In most cases the speed difference won't make any practical difference though.
Does document.getElementById("blue") exist? if it doesn't then blue_box will be equal to null. you can't set a onclick on something that's null
Nanda's answer wasn't enough in my setup. What I needed to do is:
A simple way to achieve what you want:
import cv2
s_img = cv2.imread("smaller_image.png")
l_img = cv2.imread("larger_image.jpg")
x_offset=y_offset=50
l_img[y_offset:y_offset+s_img.shape[0], x_offset:x_offset+s_img.shape[1]] = s_img
I suppose you want to take care of the alpha channel too. Here is a quick and dirty way of doing so:
s_img = cv2.imread("smaller_image.png", -1)
y1, y2 = y_offset, y_offset + s_img.shape[0]
x1, x2 = x_offset, x_offset + s_img.shape[1]
alpha_s = s_img[:, :, 3] / 255.0
alpha_l = 1.0 - alpha_s
for c in range(0, 3):
l_img[y1:y2, x1:x2, c] = (alpha_s * s_img[:, :, c] +
alpha_l * l_img[y1:y2, x1:x2, c])
You can pass values by using the below .
@Html.ActionLink("About", "About", "Home",new { name = ViewBag.Name }, htmlAttributes:null )
Controller:
public ActionResult About(string name)
{
ViewBag.Message = "Your application description page.";
ViewBag.NameTransfer = name;
return View();
}
And the URL looks like
http://localhost:50297/Home/About?name=My%20Name%20is%20Vijay
Bind variable can be used in Oracle SQL query with "in" clause.
Works in 10g; I don't know about other versions.
Bind variable is varchar up to 4000 characters.
Example: Bind variable containing comma-separated list of values, e.g.
:bindvar = 1,2,3,4,5
select * from mytable
where myfield in
(
SELECT regexp_substr(:bindvar,'[^,]+', 1, level) items
FROM dual
CONNECT BY regexp_substr(:bindvar, '[^,]+', 1, level) is not null
);
(Same info as I posted here: How do you specify IN clause in a dynamic query using a variable? )
I had same problem. It said could not copy from bin\debug to obj.....
When i build web project i found my dll were all in bin folder and not in bin\debug. During publish vs was looking for files in bin\debug. So i opened web project file in editor and look for instances of bin\debug and i found all the dll were mentioned as bin\debug\mylibrary.dll. I removed all \debug from the path and published again. This time vs was able to find all the dll in bin folder and publish succeeded.
I have no idea how this path got changed in web project file.
I spent more than 5 hours debugging this and finally found solution on my own.
This is the right answer.
All we know is "All instances of a any class shares the same java.lang.Class object of that type of class"
e.g)
Student a = new Student();
Student b = new Student();
Then a.getClass() == b.getClass()
is true.
Now assume
Teacher t = new Teacher();
without generics the below is possible.
Class studentClassRef = t.getClass();
But this is wrong now ..?
e.g) public void printStudentClassInfo(Class studentClassRef) {}
can be called with Teacher.class
This can be avoided using generics.
Class<Student> studentClassRef = t.getClass(); //Compilation error.
Now what is T ?? T is type parameters (also called type variables); delimited by angle brackets (<>), follows the class name.
T is just a symbol, like a variable name (can be any name) declared during writing of the class file. Later that T will be substituted with
valid Class name during initialization (HashMap<String> map = new HashMap<String>();
)
e.g) class name<T1, T2, ..., Tn>
So Class<T>
represents a class object of specific class type 'T
'.
Assume that your class methods has to work with unknown type parameters like below
/**
* Generic version of the Car class.
* @param <T> the type of the value
*/
public class Car<T> {
// T stands for "Type"
private T t;
public void set(T t) { this.t = t; }
public T get() { return t; }
}
Here T can be used as String
type as CarName
OR T can be used as Integer
type as modelNumber,
OR T can be used as Object
type as valid car instance.
Now here the above is the simple POJO which can be used differently at runtime.
Collections e.g) List, Set, Hashmap are best examples which will work with different objects as per the declaration of T, but once we declared T as String
e.g) HashMap<String> map = new HashMap<String>();
Then it will only accept String Class instance objects.
Generic Methods
Generic methods are methods that introduce their own type parameters. This is similar to declaring a generic type, but the type parameter's scope is limited to the method where it is declared. Static and non-static generic methods are allowed, as well as generic class constructors.
The syntax for a generic method includes a type parameter, inside angle brackets, and appears before the method's return type. For generic methods, the type parameter section must appear before the method's return type.
class Util {
// Generic static method
public static <K, V, Z, Y> boolean compare(Pair<K, V> p1, Pair<Z, Y> p2) {
return p1.getKey().equals(p2.getKey()) &&
p1.getValue().equals(p2.getValue());
}
}
class Pair<K, V> {
private K key;
private V value;
}
Here <K, V, Z, Y>
is the declaration of types used in the method arguments which should before the return type which is boolean
here.
In the below; type declaration <T>
is not required at method level, since it is already declared at class level.
class MyClass<T> {
private T myMethod(T a){
return a;
}
}
But below is wrong as class-level type parameters K, V, Z, and Y cannot be used in a static context (static method here).
class Util <K, V, Z, Y>{
// Generic static method
public static boolean compare(Pair<K, V> p1, Pair<Z, Y> p2) {
return p1.getKey().equals(p2.getKey()) &&
p1.getValue().equals(p2.getValue());
}
}
OTHER VALID SCENARIOS ARE
class MyClass<T> {
//Type declaration <T> already done at class level
private T myMethod(T a){
return a;
}
//<T> is overriding the T declared at Class level;
//So There is no ClassCastException though a is not the type of T declared at MyClass<T>.
private <T> T myMethod1(Object a){
return (T) a;
}
//Runtime ClassCastException will be thrown if a is not the type T (MyClass<T>).
private T myMethod1(Object a){
return (T) a;
}
// No ClassCastException
// MyClass<String> obj= new MyClass<String>();
// obj.myMethod2(Integer.valueOf("1"));
// Since type T is redefined at this method level.
private <T> T myMethod2(T a){
return a;
}
// No ClassCastException for the below
// MyClass<String> o= new MyClass<String>();
// o.myMethod3(Integer.valueOf("1").getClass())
// Since <T> is undefined within this method;
// And MyClass<T> don't have impact here
private <T> T myMethod3(Class a){
return (T) a;
}
// ClassCastException for o.myMethod3(Integer.valueOf("1").getClass())
// Should be o.myMethod3(String.valueOf("1").getClass())
private T myMethod3(Class a){
return (T) a;
}
// Class<T> a :: a is Class object of type T
//<T> is overriding of class level type declaration;
private <T> Class<T> myMethod4(Class<T> a){
return a;
}
}
And finally Static method always needs explicit <T>
declaration; It wont derive from class level Class<T>
. This is because of Class level T is bound with instance.

You only use the M
for a numeric literal, when you cast it's just:
decimal dtot = (decimal)doubleTotal;
Note that a floating point number is not suited to keep an exact value, so if you first add numbers together and then convert to Decimal
you may get rounding errors. You may want to convert the numbers to Decimal
before adding them together, or make sure that the numbers aren't floating point numbers in the first place.

P.S. Don't forget connect.commit()

Based on the given answers and information in the question, this is the code you should use:
public static boolean doesURLExist(URL url) throws IOException
{
// We want to check the current URL
HttpURLConnection.setFollowRedirects(false);
HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
// We don't need to get data
httpURLConnection.setRequestMethod("HEAD");
// Some websites don't like programmatic access so pretend to be a browser
httpURLConnection.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)");
int responseCode = httpURLConnection.getResponseCode();
// We only accept response code 200
return responseCode == HttpURLConnection.HTTP_OK;
}
Of course tested and working.
In your project settings.py file,set ALLOWED_HOSTS like this :

Please take a look here:
1) You can use this with Windows (incl. MinGW) as well as Linux. Alternative you can only use the code as an example.
2) Step-by-step tutorial how to use serial ports on windows
3) You can use this literally on MinGW
Here's some very, very simple code (without any error handling or settings):
#include <windows.h>
/* ... */
// Open serial port
HANDLE serialHandle;
serialHandle = CreateFile("\\\\.\\COM1", GENERIC_READ | GENERIC_WRITE, 0, 0, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, 0);
// Do some basic settings
DCB serialParams = { 0 };
serialParams.DCBlength = sizeof(serialParams);
GetCommState(serialHandle, &serialParams);
serialParams.BaudRate = baudrate;
serialParams.ByteSize = byteSize;
serialParams.StopBits = stopBits;
serialParams.Parity = parity;
SetCommState(serialHandle, &serialParams);
// Set timeouts
COMMTIMEOUTS timeout = { 0 };
timeout.ReadIntervalTimeout = 50;
timeout.ReadTotalTimeoutConstant = 50;
timeout.ReadTotalTimeoutMultiplier = 50;
timeout.WriteTotalTimeoutConstant = 50;
timeout.WriteTotalTimeoutMultiplier = 10;
SetCommTimeouts(serialHandle, &timeout);
Now you can use WriteFile()
/ ReadFile()
to write / read bytes.
Don't forget to close your connection:
CloseHandle(serialHandle);
Found a comparison of the 2 techniques (query string vs file name) here:
Version as a querystring has two problems.
First, it may not always be a browser that implements caching through which we need to bust. It is said that certain (possibly older) proxies do ignore the querystring with respect to their caching behavior.
Second, in certain more complex deployment scenarios, where you have multiple frontend and/or multiple backend servers, an upgrade is anything but instantaneous. You need to be able to serve both the old and the new version of your assets at the same time. See for example how this affects you when using Google App Engine.
I found this suggestion useful in my case:
def product_params
params.require(:product).permit(:name).tap do |whitelisted|
whitelisted[:data] = params[:product][:data]
end
end
Check this link of Xavier's comment on github.
This approach whitelists the entire params[:measurement][:groundtruth] object.
Using the original questions attributes:
def product_params
params.require(:measurement).permit(:name, :groundtruth).tap do |whitelisted|
whitelisted[:groundtruth] = params[:measurement][:groundtruth]
end
end
You can achieve this with pattern matching with the switch expression in C#8/9
FooTextBox.Text = strFoo switch
{
{ Length: >0 } s => s, // If the length of the string is greater than 0
_ => "0" // Anything else
};
long totalSeconds = currentTimeMillis / 1000;
int currentSecond = (int)totalSeconds % 60;
long totalMinutes = totalSeconds / 60;
int currentMinute = (int)totalMinutes % 60;
long totalHours = totalMinutes / 60;
int currentHour = (int)totalHours % 12;
TextView tvTime = findViewById(R.id.tvTime);
tvTime.setText((currentHour + OR - TIME YOU ARE FROM GMT) + ":" + currentMinute + ":" + currentSecond);

You'll probably want to use addEventListener
or jQuery (etc.) to register your evt handlers - this is just for brevity's sake.
For people just stumbling upon this now, I resolved an error of this type that was thrown with all the references and using statements placed properly. There's evidently some confusion with substituting in a function that returns DataTable instead of calling it on a declared DataTable. For example:
This worked for me:
DataTable dt = SomeObject.ReturnsDataTable();
List<string> ls = dt.AsEnumerable().Select(dr => dr["name"].ToString()).ToList<string>();
But this didn't:
List<string> ls = SomeObject.ReturnsDataTable().AsEnumerable().Select(dr => dr["name"].ToString()).ToList<string>();
I'm still not 100% sure why, but if anyone is frustrated by an error of this type, give this a try.
My answer is similar to the others. If you do not want to create a new function you can use what pandas has defined for you already. Use the pipe method.
df.pipe(lambda d: d[d['column'] == value])
I'd just store it as CSV, if it's simple values then it should be all you need (XML is very verbose and serializing to/from it would probably be overkill but that would be an option as well).
Here's a good answer for how to pull out CSVs with LINQ.

As of 2020, using ContentResult
is still the right approach as proposed above, but the usage is as follows:
return new System.Web.Mvc.ContentResult
{
Content = "Hi there! ?",
ContentType = "text/plain; charset=utf-8"
}
You can use fetch to do that:
fetch('some_url')
.then(function (response) {
switch (response.status) {
// status "OK"
case 200:
return response.text();
// status "Not Found"
case 404:
throw response;
}
})
.then(function (template) {
console.log(template);
})
.catch(function (response) {
// "Not Found"
console.log(response.statusText);
});
Asynchronous with arrow function version:
(async () => {
var response = await fetch('some_url');
switch (response.status) {
// status "OK"
case 200:
var template = await response.text();
console.log(template);
break;
// status "Not Found"
case 404:
console.log('Not Found');
break;
}
})();
Here's a comfortable way to do it for activity, fragment or context. It will also auto-unregister if you do it for activity/fragment (in onDestroy), if you wish:
abstract class ConnectionBroadcastReceiver : BroadcastReceiver() {
companion object {
@JvmStatic
fun registerWithoutAutoUnregister(context: Context, connectionBroadcastReceiver: ConnectionBroadcastReceiver) {
context.registerReceiver(connectionBroadcastReceiver, IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION))
}
@JvmStatic
fun registerToFragmentAndAutoUnregister(context: Context, fragment: Fragment, connectionBroadcastReceiver: ConnectionBroadcastReceiver) {
val applicationContext = context.applicationContext
registerWithoutAutoUnregister(applicationContext, connectionBroadcastReceiver)
fragment.lifecycle.addObserver(object : LifecycleObserver {
@OnLifecycleEvent(Lifecycle.Event.ON_DESTROY)
fun onDestroy() {
applicationContext.unregisterReceiver(connectionBroadcastReceiver)
}
})
}
@JvmStatic
fun registerToActivityAndAutoUnregister(activity: AppCompatActivity, connectionBroadcastReceiver: ConnectionBroadcastReceiver) {
registerWithoutAutoUnregister(activity, connectionBroadcastReceiver)
activity.lifecycle.addObserver(object : LifecycleObserver {
@OnLifecycleEvent(Lifecycle.Event.ON_DESTROY)
fun onDestroy() {
activity.unregisterReceiver(connectionBroadcastReceiver)
}
})
}
@JvmStatic
fun hasInternetConnection(context: Context): Boolean {
val info = (context.getSystemService(Context.CONNECTIVITY_SERVICE) as ConnectivityManager).activeNetworkInfo
return !(info == null || !info.isConnectedOrConnecting)
}
}
override fun onReceive(context: Context, intent: Intent) {
val hasConnection = !intent.getBooleanExtra(ConnectivityManager.EXTRA_NO_CONNECTIVITY, false)
// Log.d("AppLog", "conenctivity changed. hasConnection? $hasConnection")
onConnectionChanged(hasConnection)
}
abstract fun onConnectionChanged(hasConnection: Boolean)
}
Usage in fragment:
ConnectionBroadcastReceiver.registerToFragmentAndAutoUnregister(activity!!, this, object : ConnectionBroadcastReceiver() {
override fun onConnectionChanged(hasConnection: Boolean) {
// Log.d("AppLog", "onConnectionChanged:" + hasConnection)
}
})
I found this useful command:
npm rebuild node-sass
From the rebuild
documentation:
This is useful when you install a new version of node (or switch node versions), and must recompile all your C++ addons with the new node.js binary.
http://laravel.io/forum/10-29-2014-laravel-elixir-sass-error
I honestly suggest that you use moment.js. Just download moment.min.js
and then use this snippet to get your date in whatever format you want:
<script>
$(document).ready(function() {
// set an element
$("#date").val( moment().format('MMM D, YYYY') );
// set a variable
var today = moment().format('D MMM, YYYY');
});
</script>
Use following chart for date formats:
trunc(tran_date) = trunc(sysdate -1)
Just use the array of options, to see, which option is currently selected.
$options = array( 'one', 'two', 'three' );
$output = '';
for( $i=0; $i<count($options); $i++ ) {
$output .= '<option '
. ( $_GET['sel'] == $options[$i] ? 'selected="selected"' : '' ) . '>'
. $options[$i]
. '</option>';
}
Sidenote: I would define a value to be some kind of id for each element, else you may run into problems, when two options have the same string representation.
Run java
with -d64
or -d32
specified, it will give you an error message if it doesn't support 64-bit or 32-bit respectively. Your JVM may support both.
You try the following ways to run the multiple python scripts:
import os
print "Starting script1"
os.system("python script1.py arg1 arg2 arg3")
print "script1 ended"
print "Starting script2"
os.system("python script2.py arg1 arg2 arg3")
print "script2 ended"
Note: The execution of multiple scripts depends purely underlined operating system, and it won't be concurrent, I was new comer in Python when I answered it.
Update: I found a package: https://pypi.org/project/schedule/ Above package can be used to run multiple scripts and function, please check this and maybe on weekend will provide some example too.
i.e:
import schedule
import time
import script1, script2
def job():
print("I'm working...")
schedule.every(10).minutes.do(job)
schedule.every().hour.do(job)
schedule.every().day.at("10:30").do(job)
schedule.every(5).to(10).days.do(job)
schedule.every().monday.do(job)
schedule.every().wednesday.at("13:15").do(job)
while True:
schedule.run_pending()
time.sleep(1)
The warning from your compiler is telling you that your format specifier doesn't match the data type you're passing to it.
Try using %lx
or %llx
. For more portability, include inttypes.h
and use the PRIx64
macro.
For example: printf("val = 0x%" PRIx64 "\n", val);
(note that it's string concatenation)
I needed an easy-to-use C++ library for parsing CSV files but couldn't find any available, so I ended up building one. Rapidcsv is a C++11 header-only library which gives direct access to parsed columns (or rows) as vectors, in datatype of choice. For example:
#include <iostream>
#include <vector>
#include <rapidcsv.h>
int main()
{
rapidcsv::Document doc("../tests/msft.csv");
std::vector<float> close = doc.GetColumn<float>("Close");
std::cout << "Read " << close.size() << " values." << std::endl;
}
you can use this on your button click activity
Intent webOpen = new Intent(android.content.Intent.ACTION_VIEW);
WebOpen.setData(Uri.parse("http://www.google.com"));
startActivity(myWebLink);
and import this on your code
import android.net.Uri;
Try this
$attribute = $_product->getResource()->getAttribute('custom_attribute_code');
if ($attribute)
{
echo $attribute_value = $attribute ->getFrontend()->getValue($_product);
}
Avoid of lot of fat fingering by starting with a Dictionary in the Model
namespace EzPL8.Models
{
public class MyEggs
{
public Dictionary<int, string> Egg { get; set; }
public MyEggs()
{
Egg = new Dictionary<int, string>()
{
{ 0, "No Preference"},
{ 1, "I hate eggs"},
{ 2, "Over Easy"},
{ 3, "Sunny Side Up"},
{ 4, "Scrambled"},
{ 5, "Hard Boiled"},
{ 6, "Eggs Benedict"}
};
}
}
In the View convert it to a list for display
@Html.DropDownListFor(m => m.Egg.Keys,
new SelectList(
Model.Egg,
"Key",
"Value"))
