In Windows 64, if you did this sequence correctly:
Anaconda prompt:
conda create -n tensorflow python=3.5
activate tensorflow
pip install --ignore-installed --upgrade tensorflow
Be sure you still are in tensorflow environment. The best way to make Spyder recognize your tensorflow environment is to do this:
conda install spyder
This will install a new instance of Spyder inside Tensorflow environment. Then you must install scipy, matplotlib, pandas, sklearn and other libraries. Also works for OpenCV.
Always prefer to install these libraries with "conda install" instead of "pip".
The problem seems to be that you are not returning something in the event that your first if
-case is false.
The error you are getting states that your arrow function (comment) => {
doesn't have a return statement. While it does for when your if
-case is true, it does not return anything for when it's false.
return this.props.comments.map((comment) => {
if (comment.hasComments === true) {
return (
<div key={comment.id}>
<CommentItem className="MainComment" />
{this.props.comments.map(commentReply => {
if (commentReply.replyTo === comment.id) {
return (
<CommentItem className="SubComment"/>
)
}
})
}
</div>
)
} else {
//return something here.
}
});
edit you should take a look at Kris' answer for how to better implement what you are trying to do.
The above answers work fine too, but I've found you can usually just use message.author.send("blah blah")
instead of message.author.sendMessage("blah blah")
.
-EDIT- : This is because the sendMessage command is outdated as of v12 in Discord Js
.send tends to work better for me in general than .sendMessage, which sometimes runs into problems. Hope that helps a teeny bit!
The solution is quite simple.
In your php.ini, just uncomment the line extension=php_gd2.dll
(or .so extension for unix systems.)
Hope it helps.
Install Node js - https://nodejs.org/en/
go to folder where you have html file:
npm install http-server -g
http-server
If you have specific html file. Run following command in CMD.- http-server fileName
by default port is 8080
Go to your browser and type localhost:8080
. Your Application should
run there.
If you want to run on different port: http-server fileName -p 9000
Note : To run your .js file run:
node fileName.js
fixed by setting GSSAPIAuthentication to no in /etc/ssh/sshd_config
Please Follow this process
First of all install git bash and create a repository on git
1) Go to working directory where the file exist which you want to push on remote and create .git folder by
$ git init
2) Add the files in your new local repository.
$ git add .
Note: while you are in same folder make sure you have placed dot after command if you putting path or not putting dot that will create ambiguity
3) Commit the files that you've staged in your local repository.
$ git commit -m "First commit"**
4) after this go to git repository and copy remote URL
$ git remote add origin *remote repository URL
5)
$ git remote -v
Note: this will ask for user.email and user.name just put it as per config
6)
$ git push origin master
this will push whole committed code to FILE.git on repository
And I think we done
Enable TLs 1.2 from IE and add the following
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;
This is my best solution if I understood the question well:
Use of $object->first()
method to run the code inside if
statement once, that is when on the first loop. The same concept is true with $object->last()
.
@if($object->first())
<div class="panel user-list">
<table id="myCustomTable" class="table table-hover">
<thead>
<tr>
<th class="col-email">Email</th>
</tr>
</thead>
<tbody>
@endif
@foreach ($object as $data)
<tr class="gradeX">
<td class="col-name"><strong>{{ $data->email }}</strong></td>
</tr>
@endforeach
@if($object->last())
</tbody>
</table>
</div>
@endif
in bluehost i could not reset password; with this driver worked:
MAIL_DRIVER=sendmail
Just to be sure that this is really the "conversion" you need, please note that jks
files are keystores, a file format used to store more than one certificate and allows you to retrieve them programmatically using the Java security API, it's not a one-to-one conversion between equivalent formats.
So, if you just want to import that certificate in a new ad-hoc keystore you can do it with Keystore Explorer, a graphical tool. You'll be able to modify the keystore and the certificates contained therein like you would have done with the java terminal utilities like keytool
(but in a more accessible way).
I suggest you to do:
chmod 400 ~/.ssh/id_rsa
It works fine for me.
you can use push method only if the object is an array:
var data = new Array();
data.push({"country": "IN"}).
OR
data['country'] = "IN"
if it's just an object you can use
data.country = "IN";
My issue was similar - I had a new table i was creating that ahd to tie in to the identity users. After reading the above answers, realized it had to do with IsdentityUser and the inherited properites. I already had Identity set up as its own Context, so to avoid inherently tying the two together, rather than using the related user table as a true EF property, I set up a non-mapped property with the query to get the related entities. (DataManager is set up to retrieve the current context in which OtherEntity exists.)
[Table("UserOtherEntity")]
public partial class UserOtherEntity
{
public Guid UserOtherEntityId { get; set; }
[Required]
[StringLength(128)]
public string UserId { get; set; }
[Required]
public Guid OtherEntityId { get; set; }
public virtual OtherEntity OtherEntity { get; set; }
}
public partial class UserOtherEntity : DataManager
{
public static IEnumerable<OtherEntity> GetOtherEntitiesByUserId(string userId)
{
return Connect2Context.UserOtherEntities.Where(ue => ue.UserId == userId).Select(ue => ue.OtherEntity);
}
}
public partial class ApplicationUser : IdentityUser
{
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
return userIdentity;
}
[NotMapped]
public IEnumerable<OtherEntity> OtherEntities
{
get
{
return UserOtherEntities.GetOtherEntitiesByUserId(this.Id);
}
}
}
You can use the Postman interceptor.That you can add into the chrome extension by this link:https://chrome.google.com/webstore/detail/postman-interceptor/aicmkgpgakddgnaphhhpliifpcfhicfo
This helps you send requests which use browser cookies through the Postman app. It can also send headers which are normally restricted by Chrome but are critical for testing APIs.
And also you can enable by interceptor which is there beside the orange sync icon
You can try for following solutions step by step one of them should work for you.
I have tried all three steps but STEP 4 worked for me. Because I was using two different git accounts
STEP 1:
STEP 2
Check your current branch git branch
if you are not on branch git
checkout branch_name
.
To create new branch use git checkout -b "new branch name"
to
switch on new branch use above command
STEP 3
In the special case that you are creating a new repository starting from an old repository that you used as a template (Don't do this if this is not your case). Completely erase the git files of the old repository so you can start a new one:
rm -rf .git
and repeat STEP 1
STEP 4
On windows, you can try putting write credentials or remove git credentials from the control panel by following way and repeat STEP 1
Go to Win -> Control Panel -> Credential Manager -> Windows Credentials
I also faced the same issue. Just restarting my servers solved the issue.
$.ajax({
type: "POST",
data: formData,
url: "/Forms/GetJobData",
dataType: 'json',
contentType: false,
processData: false,
success: function (response) {
if (response.success) {
alert(response.responseText);
} else {
// DoSomethingElse()
alert(response.responseText);
}
},
error: function (response) {
alert("error!"); //
}
});
Controller:
[HttpPost]
public ActionResult GetJobData(Jobs jobData)
{
var mimeType = jobData.File.ContentType;
var isFileSupported = IsFileSupported(mimeType);
if (!isFileSupported){
// Send "false"
return Json(new { success = false, responseText = "The attached file is not supported." }, JsonRequestBehavior.AllowGet);
}
else
{
// Send "Success"
return Json(new { success = true, responseText= "Your message successfuly sent!"}, JsonRequestBehavior.AllowGet);
}
}
---Supplement:---
basically you can send multiple parameters this way:
Controller:
return Json(new {
success = true,
Name = model.Name,
Phone = model.Phone,
Email = model.Email
},
JsonRequestBehavior.AllowGet);
Html:
<script>
$.ajax({
type: "POST",
url: '@Url.Action("GetData")',
contentType: 'application/json; charset=utf-8',
success: function (response) {
if(response.success){
console.log(response.Name);
console.log(response.Phone);
console.log(response.Email);
}
},
error: function (response) {
alert("error!");
}
});
For my mac Big Sur, with gist from answers above, following steps work for me.
$ ssh-keygen -q -t rsa -N 'password' -f ~/.ssh/id_rsa
$ ssh-add ~/.ssh/id_rsa
And added ssh public key to git hub by following instruction;
If all gone well, you should be able to get the following result;
$ ssh -T [email protected]
Hi user_name! You've successfully authenticated,...
I am late for this but i want put some more solution relevant to this.
@GetMapping
public ResponseEntity<List<JSONObject>> getRole() {
return ResponseEntity.ok(service.getRole());
}
In my case I had re-named the assembly that contained the code-first entity framework model. Although the actual schema hadn't changed at all the migrations table called
dbo.__MigrationHistory
contains a list of already performed migrations based on the old assembly name. I updated the old name in the migrations table to match the new and the migration then worked again.
The only thing you need to think about in this case is, in which directory you are on your computer.
Your command line window shows C:\users\rei0d\desktop\
as your current directory.
So the only thing you really need to do is:
Remove the desktop
by "going up" with the command cd ..
.
So the complete command would be:
cd ..
ping XXX.XXX.XXX.XXX -t
@echo off
ping -t localhost|find /v ""|cmd /q /v:on /c "for /l %%a in (0) do (set "data="&set /p "data="&if defined data echo(!time! !data!)"
note: code to be used inside a batch file. To use from command line replace %%a
with %a
Start the ping, force a correct line buffered output (find /v
), and start a cmd
process with delayed expansion enabled that will do an infinite loop reading the piped data that will be echoed to console prefixed with the current time.
2015-01-08 edited:
In faster/newer machines/os versions there is a synchronization problem in previous code, making the set /p
read a line while the ping
command is still writting it and the result are line cuts.
@echo off
ping -t localhost|cmd /q /v /c "(pause&pause)>nul & for /l %%a in () do (set /p "data=" && echo(!time! !data!)&ping -n 2 localhost>nul"
Two aditional pause
commands are included at the start of the subshell (only one can be used, but as pause
consumes a input character, a CRLF pair is broken and a line with a LF is readed) to wait for input data, and a ping -n 2 localhost
is included to wait a second for each read in the inner loop. The result is a more stable behaviour and less CPU usage.
NOTE: The inner ping
can be replaced with a pause
, but then the first character of each readed line is consumed by the pause
and not retrieved by the set /p
public class Application {
private static List<HttpMessageConverter<?>> getMessageConverters() {
List<HttpMessageConverter<?>> converters = new ArrayList<HttpMessageConverter<?>>();
converters.add(new MappingJacksonHttpMessageConverter());
return converters;
}
public static void main(String[] args) {
RestTemplate restTemplate = new RestTemplate();
restTemplate.setMessageConverters(getMessageConverters());
HttpHeaders headers = new HttpHeaders();
headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
HttpEntity<String> entity = new HttpEntity<String>(headers);
//Page page = restTemplate.getForObject("http://graph.facebook.com/pivotalsoftware", Page.class);
ResponseEntity<Page> response =
restTemplate.exchange("http://graph.facebook.com/skbh86", HttpMethod.GET, entity, Page.class, "1");
Page page = response.getBody();
System.out.println("Name: " + page.getId());
System.out.println("About: " + page.getFirst_name());
System.out.println("Phone: " + page.getLast_name());
System.out.println("Website: " + page.getMiddle_name());
System.out.println("Website: " + page.getName());
}
}
Supposing that you have a list and avoiding the isPresent()
issue (related with optionals) you could use .iterator().hasNext()
to check if not present.
Okay, redis is pretty user friendly but there are some gotchas.
Here are just some easy commands for working with redis on Ubuntu:
install:
sudo apt-get install redis-server
start with conf:
sudo redis-server <path to conf>
sudo redis-server config/redis.conf
stop with conf:
redis-ctl shutdown
(not sure how this shuts down the pid specified in the conf. Redis must save the path to the pid somewhere on boot)
log:
tail -f /var/log/redis/redis-server.log
Also, various example confs floating around online and on this site were beyond useless. The best, sure fire way to get a compatible conf is to copy-paste the one your installation is already using. You should be able to find it here:
/etc/redis/redis.conf
Then paste it at <path to conf>
, tweak as needed and you're good to go.
You need to add the Host
parameter
$mail->Host = "ssl://smtp.gmail.com";
Also, check if you have open_ssl
enabled.
<?php
echo !extension_loaded('openssl')?"Not Available":"Available";
git stash
to save your uncommited changesgit stash list
to list your saved uncommited stashesgit stash apply stash@{x}
where x can be 0,1,2..no of stashes that you have madeAn update if one is using Express 4.2 then the timeout middleware has been removed so need to manually add it with
npm install connect-timeout
and in the code it has to be (Edited as per comment, how to include it in the code)
var timeout = require('connect-timeout');
app.use(timeout('100s'));
Solution I have json object which has data
[{"name":"Ata","email":"[email protected]"}]
You can use following approach to iterate through ng-repeat and use table format instead of list.
<div class="container" ng-controller="fetchdataCtrl">
<ul ng-repeat="item in numbers">
<li>
{{item.name}}: {{item.email}}
</li>
</ul>
</div>
You can also use jq to track down the array within the returned json and then pipe that in to a second jq
call to get its length. Suppose it was in a property called records
, like {"records":[...]}
.
$ curl https://my-source-of-json.com/list | jq -r '.records' | jq length
2
$
There's a workaround for those who want to use Chrome. This extension allows you to request any site with AJAX from any source, since it adds 'Access-Control-Allow-Origin: *'
header to the response.
As an alternative, you can add this argument to your Chrome launcher: --disable-web-security
. Note that I'd only use this for development purposes, not for normal "web surfing". For reference see Run Chromium with Flags.
As a final note, by installing the extension mentioned on the first paragraph, you can easily enable/disable CORS.
My json file was formatted exactly as the one in the question but none of the solutions here worked out. Finally I found a workaround on another Stackoverflow thread. Since this post is the first link in Google search, I put the that answer here so that other people come to this post in the future will find it more easily.
As it's been said there the valid json file needs "[" in the beginning and "]" in the end of file. Moreover, after each json item instead of "}" there must be a "},". All brackets without quotations! This piece of code just modifies the malformed json file into its correct format.
Replace this
<button type="button" value=" Send" class="btn btn-success" type="submit" id="submit">
with
<button value=" Send" class="btn btn-success" type="submit" id="submit">
(I presume you are aware that using UDP(User Datagram Protocol) does not guarantee delivery, checks for duplicates and congestion control and will just answer your question).
In your server this line:
var data = udpServer.Receive(ref groupEP);
re-assigns groupEP
from what you had to a the address you receive something on.
This line:
udpServer.Send(new byte[] { 1 }, 1);
Will not work since you have not specified who to send the data to. (It works on your client because you called connect which means send will always be sent to the end point you connected to, of course we don't want that on the server as we could have many clients). I would:
UdpClient udpServer = new UdpClient(UDP_LISTEN_PORT);
while (true)
{
var remoteEP = new IPEndPoint(IPAddress.Any, 11000);
var data = udpServer.Receive(ref remoteEP);
udpServer.Send(new byte[] { 1 }, 1, remoteEP); // if data is received reply letting the client know that we got his data
}
Also if you have server and client on the same machine you should have them on different ports.
Here's how it should look like in order to return a simple Yes
when it's checked.
<input type="checkbox" id="newsletter" name="newsletter" value="Yes" checked>
<label for="newsletter">i want to sign up for newsletter</label>
I also added the text as a label, it means you can click the text as well to check the box. Small but, personally I hate when sites make me aim my mouse at this tiny little check box.
When the form is submitted if the check box is checked $_POST['newsletter']
will equal Yes
. Just how you are checking to see if $_POST['name']
,$_POST['email']
, and $_POST['tel']
are empty you could do the same.
Here is an example of how you would add this into your email on the php side:
Underneath your existing code:
$name = $_POST['name'];
$email_address = $_POST['email'];
$message = $_POST['tel'];
Add:
$newsletter = $_POST['newsletter'];
if ($newsletter != 'Yes') {
$newsletter = 'No';
}
If the check box is checked it will add Yes
in your email if it was not checked it will add No
.
For the first question I think answer would be:
<your DataFrame>.rename(columns={'count':'Total_Numbers'})
or
<your DataFrame>.columns = ['ID', 'Region', 'Total_Numbers']
As for second one I'd say the answer would be no. It's possible to use it like 'df.ID' because of python datamodel:
Attribute references are translated to lookups in this dictionary, e.g., m.x is equivalent to m.dict["x"]
You're mapping this JSON
{
"id": 2,
"socket": "0c317829-69bf-43d6-b598-7c0c550635bb",
"type": "getDashboard",
"data": {
"workstationUuid": "ddec1caa-a97f-4922-833f-632da07ffc11"
},
"reply": true
}
that contains an element named data
that has a JSON object as its value. You are trying to deserialize the element named workstationUuid
from that JSON object into this setter.
@JsonProperty("workstationUuid")
public void setWorkstation(String workstationUUID) {
This won't work directly because Jackson sees a JSON_OBJECT, not a String.
Try creating a class Data
public class Data { // the name doesn't matter
@JsonProperty("workstationUuid")
private String workstationUuid;
// getter and setter
}
the switch up your method
@JsonProperty("data")
public void setWorkstation(Data data) {
// use getter to retrieve it
in php.ini file,uncomment this one
sendmail_path = "\"C:\xampp\sendmail\sendmail.exe\" -t"

git revert
simply creates a new commit that is the opposite of an existing commit.
It leaves the files in the same state as if the commit that has been reverted never existed. For example, consider the following simple example:
$ cd /tmp/example
$ git init
Initialized empty Git repository in /tmp/example/.git/
$ echo "Initial text" > README.md
$ git add README.md
$ git commit -m "initial commit"
[master (root-commit) 3f7522e] initial commit
1 file changed, 1 insertion(+)
create mode 100644 README.md
$ echo "bad update" > README.md
$ git commit -am "bad update"
[master a1b9870] bad update
1 file changed, 1 insertion(+), 1 deletion(-)
In this example the commit history has two commits and the last one is a mistake. Using git revert:
$ git revert HEAD
[master 1db4eeb] Revert "bad update"
1 file changed, 1 insertion(+), 1 deletion(-)
There will be 3 commits in the log:
$ git log --oneline
1db4eeb Revert "bad update"
a1b9870 bad update
3f7522e initial commit
So there is a consistent history of what has happened, yet the files are as if the bad update never occured:
cat README.md
Initial text
It doesn't matter where in the history the commit to be reverted is (in the above example, the last commit is reverted - any commit can be reverted).
do you have to do something else after?
A git revert
is just another commit, so e.g. push to the remote so that other users can pull/fetch/merge the changes and you're done.
Do you have to commit the changes revert made or does revert directly commit to the repo?
git revert
is a commit - there are no extra steps assuming reverting a single commit is what you wanted to do.
Obviously you'll need to push again and probably announce to the team.
Indeed - if the remote is in an unstable state - communicating to the rest of the team that they need to pull to get the fix (the reverting commit) would be the right thing to do :).
It's worth noting that if you have a button in Controller A and the element you want to show in Controller B, you may need to use dot notation to access the scope variable across controllers.
For example, this will not work:
<div ng-controller="ControllerA">
<a ng-click="isReplyFormOpen = !isReplyFormOpen">Reply</a>
<div ng-controller="ControllerB">
<div ng-show="isReplyFormOpen" id="replyForm">
</div>
</div>
</div>
To solve this, create a global variable (ie. in Controller A or your main Controller):
.controller('ControllerA', function ($scope) {
$scope.global = {};
}
Then add a 'global' prefix to your click and show variables:
<div ng-controller="ControllerA">
<a ng-click="global.isReplyFormOpen = !global.isReplyFormOpen">Reply</a>
<div ng-controller="ControllerB">
<div ng-show="global.isReplyFormOpen" id="replyForm">
</div>
</div>
</div>
For more detail, check out the Nested States & Nested Views in the Angular-UI documentation, watch a video, or read understanding scopes.
Check this one. It will work.

Firstly, use these settings for Google:
$mail->IsSMTP();
$mail->Host = "smtp.gmail.com";
$mail->SMTPAuth = true;
$mail->SMTPSecure = "tls"; //edited from tsl
$mail->Username = "myEmail";
$mail->Password = "myPassword";
$mail->Port = "587";
But also, what firewall have you got set up?
If you're filtering out TCP ports 465/995, and maybe 587, you'll need to configure some exceptions or take them off your rules list.
You are doing all well. Just you have to check different SMTP ports like 465 and others that works on your system.
Another thing to keep in mind to allow access to the less secure apps by google account otherwise it throws the same error.
I have gone through it for a whole day and the only thing I am doing wrong is the port no., I just changed the port no. and it works.
What we usually do with e-mail, preventing spam-folders as the end destination, is using either Gmail as the smtp server or Mandrill as the smtp server.
to fix this, I had to change permissions for whole directory to 755 (777 did not work for me), and changed file owners for whole directory
chmod -R 755 public_html
chown -R nobody:nobody public_html
nobody is user that runs php in my computer.
You can solve the issue by clearing value of address in endpoint tag in web.config:
<endpoint address="" name="wsHttpEndpoint" ....... />
I have figured out how this is done for Sony devices.
I've blogged about it here. I've also posted a seperate SO question about this here.
Sony devices use a class named BadgeReciever
.
Declare the com.sonyericsson.home.permission.BROADCAST_BADGE
permission in your manifest file:
Broadcast an Intent
to the BadgeReceiver
:
Intent intent = new Intent();
intent.setAction("com.sonyericsson.home.action.UPDATE_BADGE");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.ACTIVITY_NAME", "com.yourdomain.yourapp.MainActivity");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", true);
intent.putExtra("com.sonyericsson.home.intent.extra.badge.MESSAGE", "99");
intent.putExtra("com.sonyericsson.home.intent.extra.badge.PACKAGE_NAME", "com.yourdomain.yourapp");
sendBroadcast(intent);
Done. Once this Intent
is broadcast the launcher should show a badge on your application icon.
To remove the badge again, simply send a new broadcast, this time with SHOW_MESSAGE
set to false:
intent.putExtra("com.sonyericsson.home.intent.extra.badge.SHOW_MESSAGE", false);
I've excluded details on how I found this to keep the answer short, but it's all available in the blog. Might be an interesting read for someone.
Right after @mail($email_to, $email_subject, $email_message, $headers);
header('Location: nextpage.php');
Note that you will never see 'Thanks for subscribing to our mailing list'
That should be on the next page, if you echo any text you will get an error because the headers would have been already created, if you want to redirect never return any text, not even a space!
I had this same issue and it turned out to be an improper usage of an java API. I was initializing a builder in a batch processing method that was that not supposed to be initiallized more than once.
Basically I was doing something like:
for (batch in batches) {
process_batch(batch)
}
def process_batch(batch) {
var client = TransportClient.builder().build()
client.processList(batch)
}
when I should have done this:
for (batch in batches) {
var client = TransportClient.builder().build()
process_batch(batch, client)
}
def process_batch(batch, client) {
client.processList(batch)
}
to get the object you do not need to use cURL (you are loading another dll into memory and have another dependency, unless you really need curl I'd stick with built in php functions), you can use one simple php file_get_contents(url) function: http://il1.php.net/manual/en/function.file-get-contents.php
$unparsed_json = file_get_contents("api.php?action=getThreads&hash=123fajwersa&node_id=4&order_by=post_date&order=desc&limit=1&grab_content&content_limit=1");
$json_object = json_decode($unparsed_json);
then json_decode() parses JSON into a PHP object, or an array if you pass true
to the second parameter.
http://php.net/manual/en/function.json-decode.php
For example:
$json = '{"a":1,"b":2,"c":3,"d":4,"e":5}';
var_dump(json_decode($json)); // Object
var_dump(json_decode($json, true)); // Associative array
It's not Twitter bootstrap specific, it is a normal HTML5 component and you can specify the range with the min
and max
attributes (in your case only the first attribute). For example:
<div> _x000D_
<input type="number" id="replyNumber" min="0" data-bind="value:replyNumber" />_x000D_
</div>
_x000D_
I'm not sure if only integers are allowed by default in the control or not, but else you can specify the step
attribute:
<div> _x000D_
<input type="number" id="replyNumber" min="0" step="1" data-bind="value:replyNumber" />_x000D_
</div>
_x000D_
Now only numbers higher (and equal to) zero can be used and there is a step of 1, which means the values are 0, 1, 2, 3, 4, ... .
BE AWARE: Not all browsers support the HTML5 features, so it's recommended to have some kind of JavaScript fallback (and in your back-end too) if you really want to use the constraints.
For a list of browsers that support it, you can look at caniuse.com.
Try using the smtpsend program that comes with JavaMail, as described here. If that fails in the same way, there's something wrong with your JDK configuration or your network configuration.
Anderscc has got it correct. Thanks. It worked for me but not 100%.
I had to set
$mail->SMTPDebug = 0;
Setting it to 1, can cause errors especially if you are passing some data as json to next page. Example - Performing verification if mail is sent, using json to pass data through ajax.
I had to lower my gmail account security settings to get rid of errors: " SMTP connect() failed " and " SMTP ERROR: Password command failed "
Solution: This problem can be caused by either 'less secure' applications trying to use the email account (this is according to google help, not sure how they judge what is secure and what is not) OR if you are trying to login several time in a row OR if you change countries (for example use VPN, move code to different server or actually try to login from different part of the world).
Links that fix the problem (you must be logged into google account):
view recent attempts to use the account and accept suspicious access.
link to disable the feature of blocking suspicious apps/technologies:
Note: You can go to the following stackoverflow answer link for more detailed reference.
First you better set debug to TRUE:
$email->SMTPDebug = true;
Or temporary change value of public $SMTPDebug = false; in PHPMailer class.
And then you can see the full log in the browser. For me it was too many emails per second:
...
SMTP -> FROM SERVER:XXX.XX.XX.X Ok
SMTP -> get_lines(): $data was ""
SMTP -> get_lines(): $str is "XXX.XX.XX.X Requested action not taken: too many emails per second "
SMTP -> get_lines(): $data is "XXX.XX.XX.X Requested action not taken: too many emails per second "
SMTP -> FROM SERVER:XXX.XX.XX.X Requested action not taken: too many emails per second
SMTP -> ERROR: DATA command not accepted from server: 550 5.7.0 Requested action not taken: too many emails per second
...
Thus I got to know what was the exact issue.
When I ran into this error, I spent hours trying to find a solution.
My issue was that when I went to save the file I had accidentally hit the key stroke "G" in the web.config. I had a straggler Character just sittings outside, so the web.config did not know how to interpret the improperly formatted data.
Hope this helps.
Alternative way of achieving same result is not to use JOIN
keyword at all.
UPDATE TABLE_A, TABLE_B
SET TABLE_A.column_c = TABLE_B.column_c + 1
WHERE TABLE_A.join_col = TABLE_B.join_col
I'm posting this in case someone faces the same problem I am facing right now. I've got a Zebra thermal printer, equipped with the ZebraNet print server, which offers a HTML-based user interface for editing multiple settings, seeing the printer's current status, etc. I need to get the status of the printer, which is displayed in one of those html pages, offered by the ZebraNet server and, for example, alert() a message to the user in the browser. This means that I have to get that html page in Javascript first. Although the printer is within the LAN of the user's PC, that Same Origin Policy is still staying firmly in my way. I tried JSONP, but the server returns html and I haven't found a way to modify its functionality (if I could, I would have already set the magic header Access-control-allow-origin: *). So I decided to write a small console app in C#. It has to be run as Admin to work properly, otherwise it trolls :D an exception. Here is some code:
// Create a listener.
HttpListener listener = new HttpListener();
// Add the prefixes.
//foreach (string s in prefixes)
//{
// listener.Prefixes.Add(s);
//}
listener.Prefixes.Add("http://*:1234/"); // accept connections from everywhere,
//because the printer is accessible only within the LAN (no portforwarding)
listener.Start();
Console.WriteLine("Listening...");
// Note: The GetContext method blocks while waiting for a request.
HttpListenerContext context;
string urlForRequest = "";
HttpWebRequest requestForPage = null;
HttpWebResponse responseForPage = null;
string responseForPageAsString = "";
while (true)
{
context = listener.GetContext();
HttpListenerRequest request = context.Request;
urlForRequest = request.RawUrl.Substring(1, request.RawUrl.Length - 1); // remove the slash, which separates the portNumber from the arg sent
Console.WriteLine(urlForRequest);
//Request for the html page:
requestForPage = (HttpWebRequest)WebRequest.Create(urlForRequest);
responseForPage = (HttpWebResponse)requestForPage.GetResponse();
responseForPageAsString = new StreamReader(responseForPage.GetResponseStream()).ReadToEnd();
// Obtain a response object.
HttpListenerResponse response = context.Response;
// Send back the response.
byte[] buffer = System.Text.Encoding.UTF8.GetBytes(responseForPageAsString);
// Get a response stream and write the response to it.
response.ContentLength64 = buffer.Length;
response.AddHeader("Access-Control-Allow-Origin", "*"); // the magic header in action ;-D
System.IO.Stream output = response.OutputStream;
output.Write(buffer, 0, buffer.Length);
// You must close the output stream.
output.Close();
//listener.Stop();
All the user needs to do is run that console app as Admin. I know it is way too ... frustrating and complicated, but it is sort of a workaround to the Domain Policy problem in case you cannot modify the server in any way.
edit: from js I make a simple ajax call:
$.ajax({
type: 'POST',
url: 'http://LAN_IP:1234/http://google.com',
success: function (data) {
console.log("Success: " + data);
},
error: function (e) {
alert("Error: " + e);
console.log("Error: " + e);
}
});
The html of the requested page is returned and stored in the data variable.
I will recommend to use an alternative method using seaborn
which more powerful tool for data plotting. You can use seaborn scatterplot
and define colum 3 as hue
and size
.
Working code:
import pandas as pd
import seaborn as sns
import numpy as np
#creating sample data
sample_data={'col_name_1':np.random.rand(20),
'col_name_2': np.random.rand(20),'col_name_3': np.arange(20)*100}
df= pd.DataFrame(sample_data)
sns.scatterplot(x="col_name_1", y="col_name_2", data=df, hue="col_name_3",size="col_name_3")
In my case, I had trouble with GoDaddy and SSL encryption.
Setting the encryption to Null and Port to 80 (Or any supportive port) did the job.
You are using a wrong overload of the Html.ActionLink
helper. What you think is routeValues
is actually htmlAttributes
! Just look at the generated HTML, you will see that this anchor's href property doesn't look as you expect it to look.
Here's what you are using:
@Html.ActionLink(
"Reply", // linkText
"BlogReplyCommentAdd", // actionName
"Blog", // routeValues
new { // htmlAttributes
blogPostId = blogPostId,
replyblogPostmodel = Model,
captchaValid = Model.AddNewComment.DisplayCaptcha
}
)
and here's what you should use:
@Html.ActionLink(
"Reply", // linkText
"BlogReplyCommentAdd", // actionName
"Blog", // controllerName
new { // routeValues
blogPostId = blogPostId,
replyblogPostmodel = Model,
captchaValid = Model.AddNewComment.DisplayCaptcha
},
null // htmlAttributes
)
Also there's another very serious issue with your code. The following routeValue:
replyblogPostmodel = Model
You cannot possibly pass complex objects like this in an ActionLink. So get rid of it and also remove the BlogPostModel
parameter from your controller action. You should use the blogPostId
parameter to retrieve the model from wherever this model is persisted, or if you prefer from wherever you retrieved the model in the GET action:
public ActionResult BlogReplyCommentAdd(int blogPostId, bool captchaValid)
{
BlogPostModel model = repository.Get(blogPostId);
...
}
As far as your initial problem is concerned with the wrong overload I would recommend you writing your helpers using named parameters:
@Html.ActionLink(
linkText: "Reply",
actionName: "BlogReplyCommentAdd",
controllerName: "Blog",
routeValues: new {
blogPostId = blogPostId,
captchaValid = Model.AddNewComment.DisplayCaptcha
},
htmlAttributes: null
)
Now not only that your code is more readable but you will never have confusion between the gazillions of overloads that Microsoft made for those helpers.
No, you can't instantite an abstract class.We instantiate only anonymous class.In abstract class we declare abstract methods and define concrete methods only.
Steps:
Create ssh keys on source server
ssh-keygen
Cat and copy id_rsa.pub located under ~./ssh directory
Check if it works by running below command on the source server
git remote show origin
For fetch and push from the source server, if the protocol is 'https' then you have to change it to 'git+ssh' by running below command
git remote set-url origin git+ssh://<bitbucketaccount>@bitbucket.org/<accountname>/repo.git
Check if you can do push to the repo.
Done!
It is worth noting that you can build upon Gavin Toweys answer by using multiple fields from across your query such as
SUM(table.field = 1 AND table2.field = 2)
You can also use this syntax for COUNT
and I am sure other functions as well.
This will work:
$email_to = "[email protected],[email protected],[email protected]";
EOF is a special out-of-band signal which means the end of input. It's not a character (though in the old DOS days, 0x1B acted like EOF), but rather a signal from the OS that the input has ended.
On Windows, you can "input" an EOF by pressing Ctrl+Z
at the command prompt. This signals the terminal to close the input stream, which presents an EOF to the running program. Note that on other OSes or terminal emulators, EOF is usually signalled using Ctrl+D
.
As for your issue with Sublime Text 2, it seems that stdin
is not connected to the terminal when running a program within Sublime, and so consequently programs start off connected to an empty file (probably nul
or /dev/null
). See also Python 3.1 and Sublime Text 2 error.
When you do from socket import *
python is loading a socket
module to the current namespace. Thus you can use module's members as if they are defined within your current python module.
When you do import socket
, a module is loaded in a separate namespace. When you are accessing its members, you should prefix them with a module name. For example, if you want to refer to a socket
class, you will need to write client_socket = socket.socket(socket.AF_INET,socket.SOCK_DGRAM)
.
As for the problem with timeout - all you need to do is to change except socket.Timeouterror:
to except timeout:
, since timeout
class is defined inside socket
module and you have imported all its members to your namespace.

I have found the answer to this, and it is annoyingly/frustratingly simple! Basically the reply to addresses needed to be added before the from address as such:
$mail->addReplyTo('[email protected]', 'Reply to name');
$mail->SetFrom('[email protected]', 'Mailbox name');
Looking at the phpmailer code in more detail this is the offending line:
public function SetFrom($address, $name = '',$auto=1) {
$address = trim($address);
$name = trim(preg_replace('/[\r\n]+/', '', $name)); //Strip breaks and trim
if (!self::ValidateAddress($address)) {
$this->SetError($this->Lang('invalid_address').': '. $address);
if ($this->exceptions) {
throw new phpmailerException($this->Lang('invalid_address').': '.$address);
}
echo $this->Lang('invalid_address').': '.$address;
return false;
}
$this->From = $address;
$this->FromName = $name;
if ($auto) {
if (empty($this->ReplyTo)) {
$this->AddAnAddress('ReplyTo', $address, $name);
}
if (empty($this->Sender)) {
$this->Sender = $address;
}
}
return true;
}
Specifically this line:
if (empty($this->ReplyTo)) {
$this->AddAnAddress('ReplyTo', $address, $name);
}
Thanks for your help everyone!
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).
for safety we should not use self signed certificates in our implementation. However, when it comes to development often we have to use trial environments which got self-signed certs. I tried to fix this issue programmatically in my code and I fail. However, by adding the cert to the jre trust-store fixed my issue. Please find below steps,
Download the site cert,
Copy the certificate(ex:cert_file.cer) into the directory $JAVA_HOME\Jre\Lib\Security
Open CMD in Administrator and change the directory to $JAVA_HOME\Jre\Lib\Security
Import the certificate to a trust store using below command,
keytool -import -alias ca -file cert_file.cer -keystore cacerts -storepass changeit
If you got a error saying keytool is not recognizable please refer this.
Type yes like below
Trust this certificate: [Yes]
Update
If your app server is jboss try adding below system property
System.setProperty("org.jboss.security.ignoreHttpsHost","true");
Hope this helps!
You were setting BCC but then overwriting the variable with the FROM
$to = "[email protected]";
$subject .= "".$emailSubject."";
$headers .= "Bcc: ".$emailList."\r\n";

"X-Mailer: php";

My random guess is: TV uses x264 codec which has a commercial license (otherwise TeamViewer would have to release their source code). At some point (more than 5 years ago), I recall main developer of x264 wrote an article about improvements he made for low delay encoding (if you delay by a few frames encoders can compress better), plus he mentioned some other improvements that were relevant for TeamViewer-like use. In that post he mentioned playing quake over video stream with no noticeable issues. Back then I was kind of sure who was the sponsor of these improvements, as TeamViewer was pretty much the only option at that time. x264 is an open source implementation of H264 video codec, and it's insanely good implementation, it's the best one. At the same time it's extremely well optimized. Most likely due to extremely good implementation of x264 you get much better results with TV at lower CPU load. AnyDesk and Chrome Remote Desk use libvpx, which isn't as good as x264 (optimization and video quality wise).
However, I don't think TeamView can beat microsoft's RDP. To me it's the best, however it works between windows PCs or from Mac to Windows only. TV works even from mobiles.
Update: article was written in January 2010, so that work was done roughly 10 years ago. Also, I made a mistake: he played call of duty, not quake. When you posted your question, if my guess is correct, TeamViewer had been using that work for 3 years. Read that blog post from web archive: x264: the best low-latency video streaming platform in the world. When I read the article back in 2010, I was sure that the "startup–which has requested not to be named" that the author mentions was TeamViewer.
i use $().one()
for solve this;
When page loaded, I send ajax to server and wait to done.
Then pass result to function.$().one()
is important .Because force typehead.js to attach to input one time.

You can use json module of python to pretty print.
>>> import json
>>> print json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=4)
{
"4": 5,
"6": 7
}
So, in your case
>>> print json.dumps(json_output, indent=4)
Try to set response dataType property directly:
dataType: 'text'
and put
die('');
in the end of your php file. You've got error callback cause jquery cannot parse your response. In anyway, you may use a "complete:" callback, just to make sure your request has been processed.
There is a great library to make your life easier Dapper.Contrib.Extensions. After including this you can just write:
public int Add(Transaction transaction)
{
using (IDbConnection db = Connection)
{
return (int)db.Insert(transaction);
}
}
I have encountered a similar error today and the reason was that the support library was referenced by two library projects used by my app project but with different versions.
In more details: My app depends on 2 library projects
To solve the problem I had to make FaceBookSDK library depend on ABS library instead of the support library directly.
I have resolved this same issue by doing below steps:
File > Close Project
Import Project
Select you project via the system file popup
Check "Import project from external model" radio button and select Maven entry
And some Next buttons (select JDK, ...)
Then the project will be imported as Maven module.
For me, it relate to Firewall setting. Go to your firewall setting, allow DTC Service and it worked.
This answer needs to be updated to work with Express 4.0. Here is how I got the separate http server to work:
var express = require('express');
var http = require('http');
var https = require('https');
// Primary https app
var app = express()
var port = process.env.PORT || 3000;
app.set('env', 'development');
app.set('port', port);
var router = express.Router();
app.use('/', router);
// ... other routes here
var certOpts = {
key: '/path/to/key.pem',
cert: '/path/to/cert.pem'
};
var server = https.createServer(certOpts, app);
server.listen(port, function(){
console.log('Express server listening to port '+port);
});
// Secondary http app
var httpApp = express();
var httpRouter = express.Router();
httpApp.use('*', httpRouter);
httpRouter.get('*', function(req, res){
var host = req.get('Host');
// replace the port in the host
host = host.replace(/:\d+$/, ":"+app.get('port'));
// determine the redirect destination
var destination = ['https://', host, req.url].join('');
return res.redirect(destination);
});
var httpServer = http.createServer(httpApp);
httpServer.listen(8080);
The solution has to do with the fact that your the file holding your php configurations. i.e php.ini has uncommented the extension responsible for acting as the middleman between php and postgres, by placing a ";" in front of the statement "extension=pdo_pgsql"
Quick Fix
Thank you Joseph for your answer. However, in the method possiblyResizeChildOfContent(), the portion
else {
// keyboard probably just became hidden
frameLayoutParams.height = usableHeightSansKeyboard;
}
was not working for me, as the lower portion of view became hidden. So I had to take a global variable restoreHeight, and in the constructor, I inserted the last line
restoreHeight = frameLayoutParams.height;
and then I replaced the former mentioned part with
else {
// keyboard probably just became hidden
frameLayoutParams.height = restoreHeight;
}
But I have no idea why your code didn't work for me. It would be of great help, if someone can shed light on this.
Here is the focus listener example.
editText.setOnFocusChangeListener(new OnFocusChangeListener() {
@Override
public void onFocusChange(View view, boolean hasFocus) {
if (hasFocus) {
Toast.makeText(getApplicationContext(), "Got the focus", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(getApplicationContext(), "Lost the focus", Toast.LENGTH_LONG).show();
}
}
});
Did you try this?
let barHeight = self.navigationController?.navigationBar.frame.height ?? 0
import re
regex = re.compile(
r'^(?:http|ftp)s?://' # http:// or https://
r'(?:(?:[A-Z0-9](?:[A-Z0-9-]{0,61}[A-Z0-9])?\.)+(?:[A-Z]{2,6}\.?|[A-Z0-9-]{2,}\.?)|' #domain...
r'localhost|' #localhost...
r'\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3})' # ...or ip
r'(?::\d+)?' # optional port
r'(?:/?|[/?]\S+)$', re.IGNORECASE)
print(re.match(regex, "http://www.example.com") is not None) # True
print(re.match(regex, "example.com") is not None) # False
That should work. Better if you pass a function to val
:
$('#replyBox').val(function(i, text) {
return text + quote;
});
This way you avoid searching the element and calling val
twice.
Unless the variable k
is defined, that's probably what's causing your trouble. Something like this will do what you want:
var new_tweets = { };
new_tweets.k = { };
new_tweets.k.tweet_id = 98745521;
new_tweets.k.user_id = 54875;
new_tweets.k.data = { };
new_tweets.k.data.in_reply_to_screen_name = 'other_user';
new_tweets.k.data.text = 'tweet text';
// Will create the JSON string you're looking for.
var json = JSON.stringify(new_tweets);
You can also do it all at once:
var new_tweets = {
k: {
tweet_id: 98745521,
user_id: 54875,
data: {
in_reply_to_screen_name: 'other_user',
text: 'tweet_text'
}
}
}
That would work depending on what client.get does when passed undefined as its first parameter.
Something like this would be safer:
app.get('/:key?', function(req, res, next) {
var key = req.params.key;
if (!key) {
next();
return;
}
client.get(key, function(err, reply) {
if(client.get(reply)) {
res.redirect(reply);
}
else {
res.render('index', {
link: null
});
}
});
});
There's no problem in calling next() inside the callback.
According to this, handlers are invoked in the order that they are added, so as long as your next route is app.get('/', ...) it will be called if there is no key.
I know this is an old post, but the current answers dont address the fact that outlook and many other email providers dont support inline images or CID images. The most effective way to place images in emails is to host it online and place a link to it in the email. For small email lists a public dropbox works fine. This also keeps the email size down.
This solves my problem:
ssh-agent bash
ssh-add
Well, you want to have an answer that is up-to-date and modern.
Here is my answer:
When I need to mail in Python, I use the mailgun API wich get's a lot of the headaches with sending mails sorted out. They have a wonderfull app/api that allows you to send 5,000 free emails per month.
Sending an email would be like this:
def send_simple_message():
return requests.post(
"https://api.mailgun.net/v3/YOUR_DOMAIN_NAME/messages",
auth=("api", "YOUR_API_KEY"),
data={"from": "Excited User <mailgun@YOUR_DOMAIN_NAME>",
"to": ["[email protected]", "YOU@YOUR_DOMAIN_NAME"],
"subject": "Hello",
"text": "Testing some Mailgun awesomness!"})
You can also track events and lots more, see the quickstart guide.
I hope you find this useful!
The solution for me was to install the oracle unlimited JCE and install in JRE_HOME/lib/security. Then restarted glassfish and I was able to connect to my sftp server using jsch.
Try creating a new service and calling it. The processing can be done there, and returned back.
http://code.msdn.microsoft.com/windowsazure/WCF-Azure-AJAX-Calculator-4cf3099e
function makeCall(operation){
var n1 = document.getElementById("num1").value;
var n2 = document.getElementById("num2").value;
if(n1 && n2){
// Instantiate a service proxy
var proxy = new Service();
// Call correct operation on vf cproxy
switch(operation){
case "gridOne":
proxy.Calculate(AjaxService.Operation.getWeather, n1, n2,
onSuccess, onFail, null);
****HTML CODE****
<p>Major City: <input type="text" id="num1" onclick="return num1_onclick()"
/></p>
<p>Country: <input type="text" id="num2" onclick="return num2_onclick()"
/></p>
<input id="btnDivide" type="button" onclick="return makeCall('gridOne');"
There's actually a good reason:
The non-static access does not always work, for reasons of ambiguity.
Suppose we have two classes, A and B, the latter being a subclass of A, with static fields with the same name:
public class A {
public static String VALUE = "Aaa";
}
public class B extends A {
public static String VALUE = "Bbb";
}
Direct access to the static variable:
A.VALUE (="Aaa")
B.VALUE (="Bbb")
Indirect access using an instance (gives a compiler warning that VALUE should be statically accessed):
new B().VALUE (="Bbb")
So far, so good, the compiler can guess which static variable to use, the one on the superclass is somehow farther away, seems somehow logical.
Now to the point where it gets tricky: Interfaces can also have static variables.
public interface C {
public static String VALUE = "Ccc";
}
public interface D {
public static String VALUE = "Ddd";
}
Let's remove the static variable from B, and observe following situations:
B implements C, D
B extends A implements C
B extends A implements C, D
B extends A implements C
where A implements D
B extends A implements C
where C extends D
The statement new B().VALUE
is now ambiguous, as the compiler cannot decide which static variable was meant, and will report it as an error:
error: reference to VALUE is ambiguous
both variable VALUE in C and variable VALUE in D match
And that's exactly the reason why static variables should be accessed in a static way.
This answer took me forever to find as well. I discovered that all you have to do is concatenate the URL ('?' after the file name and extension) with the URL-encoded query string. It doesn't even look like you have to set the POST cURL options. See the fake example below:
//create URL
$exampleURL = 'http://www.example.com/example.php?';
// create curl resource
$ch = curl_init();
// build URL-encoded query string
$data = http_build_query(
array('first' => 'John', 'last' => 'Smith', '&'); // set url
curl_setopt($ch, CURLOPT_URL, $exampleURL . $data);
// return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources <br/>
curl_close($ch);
You can also use file_get_contents()
:
// read entire webpage file into a string
$output = file_get_contents($exampleURL . $data);
You can specify the name attribute as below:
$( 'input[name="testGroup"]:radio' ).change(
Axes sizing in MATLAB can be a bit tricky sometimes. You are correct to suspect the paper sizing properties as one part of the problem. Another is the automatic margins MATLAB calculates. Fortunately, there are settable axes properties that allow you to circumvent these margins. You can reset the margins to be just big enough for axis labels using a combination of the Position
and TightInset
properties which are explained here. Try this:
>> h = figure; >> axes; >> set(h, 'InvertHardcopy', 'off'); >> saveas(h, 'WithMargins.pdf');
and you'll get a PDF that looks like: but now do this:
>> tightInset = get(gca, 'TightInset'); >> position(1) = tightInset(1); >> position(2) = tightInset(2); >> position(3) = 1 - tightInset(1) - tightInset(3); >> position(4) = 1 - tightInset(2) - tightInset(4); >> set(gca, 'Position', position); >> saveas(h, 'WithoutMargins.pdf');
and you'll get:
Just to go a little bit further in the matter, you can also set a bitmap directly, like this:
ImageView imageView = new ImageView(this);
Bitmap bImage = BitmapFactory.decodeResource(this.getResources(), R.drawable.my_image);
imageView.setImageBitmap(bImage);
Of course, this technique is only useful if you need to change the image.
This will log the id of the element that's been clicked: addFields.

object = copyWithoutCircularReferences([object], object);_x000D_

if (value && typeof value === 'object') {_x000D_
if (references.indexOf(value) < 0) {_x000D_

Mixing Bash and Expect is not a good way to achieve the desired effect. I'd try to use only Expect:
#!/usr/bin/expect
eval spawn ssh -oStrictHostKeyChecking=no -oCheckHostIP=no usr@$myhost.example.com
# Use the correct prompt
set prompt ":|#|\\\$"
interact -o -nobuffer -re $prompt return
send "my_password\r"
interact -o -nobuffer -re $prompt return
send "my_command1\r"
interact -o -nobuffer -re $prompt return
send "my_command2\r"
interact
Sample solution for bash could be:
#!/bin/bash
/usr/bin/expect -c 'expect "\n" { eval spawn ssh -oStrictHostKeyChecking=no -oCheckHostIP=no usr@$myhost.example.com; interact }'
This will wait for Enter and then return to (for a moment) the interactive session.
I tested dkarp's solution with gmail and it was filtered to spam. Use the Reply-To header instead (or in addition, although gmail apparently doesn't need it). Here's how linkedin does it:
Sender: [email protected]
From: John Doe via LinkedIn <[email protected]>
Reply-To: John Doe <[email protected]>
To: My Name <[email protected]>
Once I switched to this format, gmail is no longer filtering my messages as spam.
expr is used instead of [ rather than inside it, and variables are only expanded inside double quotes, so try this:
if expr match "$LIST" "$SOURCE"; then
But I'm not really clear what SOURCE is supposed to represent.
It looks like your code will read in a pattern from standard input, and exit if it matches a database alias, otherwise it will echo "ok". Is that what you want?
For sending data to a service you can use:
Intent intent = new Intent(getApplicationContext(), YourService.class);
intent.putExtra("SomeData","ItValue");
startService(intent);
And after in service in onStartCommand() get data from intent.
For sending data or event from a service to an application (for one or more activities):
private void sendBroadcastMessage(String intentFilterName, int arg1, String extraKey) {
Intent intent = new Intent(intentFilterName);
if (arg1 != -1 && extraKey != null) {
intent.putExtra(extraKey, arg1);
}
sendBroadcast(intent);
}
This method is calling from your service. You can simply send data for your Activity.
private void someTaskInYourService(){
//For example you downloading from server 1000 files
for(int i = 0; i < 1000; i++) {
Thread.sleep(5000) // 5 seconds. Catch in try-catch block
sendBroadCastMessage(Events.UPDATE_DOWNLOADING_PROGRESSBAR, i,0,"up_download_progress");
}
For receiving an event with data, create and register method registerBroadcastReceivers() in your activity:
private void registerBroadcastReceivers(){
broadcastReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
int arg1 = intent.getIntExtra("up_download_progress",0);
progressBar.setProgress(arg1);
}
};
IntentFilter progressfilter = new IntentFilter(Events.UPDATE_DOWNLOADING_PROGRESS);
registerReceiver(broadcastReceiver,progressfilter);
For sending more data, you can modify method sendBroadcastMessage();
. Remember: you must register broadcasts in onResume() & unregister in onStop() methods!
UPDATE
Please don't use my type of communication between Activity & Service. This is the wrong way. For a better experience please use special libs, such us:
1) EventBus from greenrobot
2) Otto from Square Inc
P.S. I'm only using EventBus from greenrobot in my projects,
On Mac OS I had to open the server's self-signed certificate with system Keychain Access tool, import it, dobubleclick it and then select "Always trust" (even though I set the same in importer). Before that, of course I ran java key took with -importcert to import same file to cacert storage.
You can attach an event listener as below. It will trigger whenever the div having selector #my-id
loads completely to DOM.
$(document).on('EventName', '#my-id', function() {
// do something
});
Inthis case EventName may be 'load' or 'click'
First of all, it is a bad design, if you need something like that, it is good idea to refactor, e.g. by renaming the method. Java allows calling of overriden method using the "super" keyword, but only one level up in the hierarchy, I am not sure, maybe Scala and some other JVM languages support it for any level.
Use your bean class like this, if your JSON data starts with an an array object. it helps you.
Users[] bean = gson.fromJson(response,Users[].class);
Users is my bean class.
Response is my JSON data.
jQuery will do the job. You can use either jQuery.ajax function, which is general one for performing ajax calls, or its wrappers: jQuery.get, jQuery.post for getting/posting data. Its very easy to use, for example, check out this tutorial, which shows how to use jQuery with PHP.
Since some of the answers give here relate to setting up SMTP in general (and not just for @shinod particular issue where it had been working and stopped), I thought it would be helpful if I updated the answer because this is a lot simpler to do now than it used to be :-)
In PHP 4 the PEAR Mail package is typically already installed, and this really simple tutorial shows you the few lines of code that you need to add to your php file http://email.about.com/od/emailprogrammingtips/qt/PHP_Email_SMTP_Authentication.htm
Most hosting companies list the SMTP settings that you'll need. I use JustHost, and they list theirs at https://my.justhost.com/cgi/help/26 (under Outgoing Mail Server)
Important:
I'm sorry to say that the response from "Borealid" is imprecise and somewhat incorrect - firstly there is no relation to statefulness or statelessness to answer this question, and most importantly the definition of the tuple for a socket is incorrect.
First remember below two rules:
Primary key of a socket: A socket is identified by {SRC-IP, SRC-PORT, DEST-IP, DEST-PORT, PROTOCOL}
not by {SRC-IP, SRC-PORT, DEST-IP, DEST-PORT}
- Protocol is an important part of a socket's definition.
OS Process & Socket mapping: A process can be associated with (can open/can listen to) multiple sockets which might be obvious to many readers.
Example 1: Two clients connecting to same server port means: socket1 {SRC-A, 100, DEST-X,80, TCP}
and socket2{SRC-B, 100, DEST-X,80, TCP}
. This means host A connects to server X's port 80 and another host B also connects to same server X to the same port 80. Now, how the server handles these two sockets depends on if the server is single threaded or multiple threaded (I'll explain this later). What is important is that one server can listen to multiple sockets simultaneously.
To answer the original question of the post:
Irrespective of stateful or stateless protocols, two clients can connect to same server port because for each client we can assign a different socket (as client IP will definitely differ). Same client can also have two sockets connecting to same server port - since such sockets differ by SRC-PORT
. With all fairness, "Borealid" essentially mentioned the same correct answer but the reference to state-less/full was kind of unnecessary/confusing.
To answer the second part of the question on how a server knows which socket to answer. First understand that for a single server process that is listening to same port, there could be more than one sockets (may be from same client or from different clients). Now as long as a server knows which request is associated with which socket, it can always respond to appropriate client using the same socket. Thus a server never needs to open another port in its own node than the original one on which client initially tried to connect. If any server allocates different server-ports after a socket is bound, then in my opinion the server is wasting its resource and it must be needing the client to connect again to the new port assigned.
A bit more for completeness:
Example 2: It's a very interesting question: "can two different processes on a server listen to the same port". If you do not consider protocol as one of parameter defining socket then the answer is no. This is so because we can say that in such case, a single client trying to connect to a server-port will not have any mechanism to mention which of the two listening processes the client intends to connect to. This is the same theme asserted by rule (2). However this is WRONG answer because 'protocol' is also a part of the socket definition. Thus two processes in same node can listen to same port only if they are using different protocol. For example two unrelated clients (say one is using TCP and another is using UDP) can connect and communicate to the same server node and to the same port but they must be served by two different server-processes.
Server Types - single & multiple:
When a server's processes listening to a port that means multiple sockets can simultaneously connect and communicate with the same server-process. If a server uses only a single child-process to serve all the sockets then the server is called single-process/threaded and if the server uses many sub-processes to serve each socket by one sub-process then the server is called multi-process/threaded server. Note that irrespective of the server's type a server can/should always uses the same initial socket to respond back (no need to allocate another server-port).
Suggested Books and rest of the two volumes if you can.
A Note on Parent/Child Process (in response to query/comment of 'Ioan Alexandru Cucu')
Wherever I mentioned any concept in relation to two processes say A and B, consider that they are not related by parent child relationship. OS's (especially UNIX) by design allow a child process to inherit all File-descriptors (FD) from parents. Thus all the sockets (in UNIX like OS are also part of FD) that a process A listening to, can be listened by many more processes A1, A2, .. as long as they are related by parent-child relation to A. But an independent process B (i.e. having no parent-child relation to A) cannot listen to same socket. In addition, also note that this rule of disallowing two independent processes to listen to same socket lies on an OS (or its network libraries) and by far it's obeyed by most OS's. However, one can create own OS which can very well violate this restrictions.
I finally got a proof-of-concept project to work, so I will share it here.

According to the documentation, Android should support mp4 H.264 playback (decoding) for all API levels. However, there seem to be a lot of factors that affect whether an actual video will play or not. The most in depth answer I could find that told how to encode the videos is here. It uses the powerful ffmpeg
command line tool to do the conversion to something that should be playable on all (hopefully?) Android devices. Read the answer I linked to for more explanation. I used a slightly modified version because I was getting errors with the original version.
ffmpeg -y -i input_file.avi -s 432x320 -b:v 384k -vcodec libx264 -flags +loop+mv4 -cmp 256 -partitions +parti4x4+parti8x8+partp4x4+partp8x8 -subq 6 -trellis 0 -refs 5 -bf 0 -coder 0 -me_range 16 -g 250 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -qmin 10 -qmax 51 -qdiff 4 -c:a aac -ac 1 -ar 16000 -r 13 -ab 32000 -aspect 3:2 -strict -2 output_file.mp4
I would definitely read up a lot more on each of those parameters to see which need adjusting as far as video and audio quality go.
Next, rename output_file.mp4
to test.mp4
and put it in your Android project's /res/raw
folder. Create the folder if it doesn't exist already.
There is not much to the code. The video plays when the "Play" button is clicked. Thanks to this answer for help.
MainActivity.java
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void onButtonClick(View v) {
VideoView videoview = (VideoView) findViewById(R.id.videoview);
Uri uri = Uri.parse("android.resource://"+getPackageName()+"/"+R.raw.test);
videoview.setVideoURI(uri);
videoview.start();
}
}
That's all. You should be able play your video clip on the simulator or a real device now.
Use the backslash to escape a character. For example:
/\\d/
This will match \d instead of a numeric character
Why not convert the string to an integer of the form YYYYMMDDHHMMSS? Each increment of time would then create a larger integer, and you can filter on the integers instead of worrying about converting to ISO time.
Reading one line of text at a time, and appending said line to a string individually is time-consuming both in extracting each line and the overhead of so many method invocations.
I was able to get better performance by allocating a decent-sized byte array to hold the stream data, and which is iteratively replaced with a larger array when needed, and trying to read as much as the array could hold.
For some reason, Android repeatedly failed to download the entire file when the code used the InputStream returned by HTTPUrlConnection, so I had to resort to using both a BufferedReader and a hand-rolled timeout mechanism to ensure I would either get the whole file or cancel the transfer.
private static final int kBufferExpansionSize = 32 * 1024;
private static final int kBufferInitialSize = kBufferExpansionSize;
private static final int kMillisecondsFactor = 1000;
private static final int kNetworkActionPeriod = 12 * kMillisecondsFactor;
private String loadContentsOfReader(Reader aReader)
{
BufferedReader br = null;
char[] array = new char[kBufferInitialSize];
int bytesRead;
int totalLength = 0;
String resourceContent = "";
long stopTime;
long nowTime;
try
{
br = new BufferedReader(aReader);
nowTime = System.nanoTime();
stopTime = nowTime + ((long)kNetworkActionPeriod * kMillisecondsFactor * kMillisecondsFactor);
while(((bytesRead = br.read(array, totalLength, array.length - totalLength)) != -1)
&& (nowTime < stopTime))
{
totalLength += bytesRead;
if(totalLength == array.length)
array = Arrays.copyOf(array, array.length + kBufferExpansionSize);
nowTime = System.nanoTime();
}
if(bytesRead == -1)
resourceContent = new String(array, 0, totalLength);
}
catch(Exception e)
{
e.printStackTrace();
}
try
{
if(br != null)
br.close();
}
catch(IOException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
}
EDIT: It turns out that if you don't need to have the content re-encoded (ie, you want the content AS IS) you shouldn't use any of the Reader subclasses. Just use the appropriate Stream subclass.
Replace the beginning of the preceding method with the corresponding lines of the following to speed it up an extra 2 to 3 times.
String loadContentsFromStream(Stream aStream)
{
BufferedInputStream br = null;
byte[] array;
int bytesRead;
int totalLength = 0;
String resourceContent;
long stopTime;
long nowTime;
resourceContent = "";
try
{
br = new BufferedInputStream(aStream);
array = new byte[kBufferInitialSize];
what error do you get is it a SmtpFailedrecipientException? if so you can check the innerexceptions list and view the StatusCode to get more information. the link below has some good information
Edit for the new information
Thisis a problem with finding your SMTP server from what I can see, though you say that it only happens on some emails. Are you using more than one smtp server and if so maybe you can tract the issue down to one in particular, if not it may be that the speed/amount of emails you are sending is causing your smtp server some issue.
headers were not working for me on my shared hosting, reason was i was using my hotmail email address in header. i created a email on my cpanel and i set that same email in the header yeah it worked like a charm!
$header = 'From: ShopFive <[email protected]>' . "\r\n";
Someone who also has xml files, might want to look at my Xidel. It is a cli, dependency-free JSONiq processor. (i.e. it also supports XQuery for xml or json processing)
The example in the question would be:
xidel -e 'json("http://twitter.com/users/username.json")("name")'
Or with my own, non standard extension syntax:
xidel -e 'json("http://twitter.com/users/username.json").name'
In my case it was server redirection; curl -L
solved my problem.
this works for me every time try this.
echo "<font color='blue'>".$myvariable."</font>";
since font is not supported in html5 you can do this
echo "<p class="variablecolor">".$myvariable."</p>";
then in css do
.variablecolor{
color: blue;}
Either decorate your root entity with the XmlRoot attribute which will be used at compile time.
[XmlRoot(Namespace = "www.contoso.com", ElementName = "MyGroupName", DataType = "string", IsNullable=true)]
Or specify the root attribute when de serializing at runtime.
XmlRootAttribute xRoot = new XmlRootAttribute();
xRoot.ElementName = "user";
// xRoot.Namespace = "http://www.cpandl.com";
xRoot.IsNullable = true;
XmlSerializer xs = new XmlSerializer(typeof(User),xRoot);
You need to change the sshd_config
file in the remote server (probably in /etc/ssh/sshd_config
).
Change
PasswordAuthentication no
to
PasswordAuthentication yes
And then restart the sshd
daemon.
In your binding configuration, there are four timeout values you can tweak:
<bindings>
<basicHttpBinding>
<binding name="IncreasedTimeout"
sendTimeout="00:25:00">
</binding>
</basicHttpBinding>
The most important is the sendTimeout
, which says how long the client will wait for a response from your WCF service. You can specify hours:minutes:seconds
in your settings - in my sample, I set the timeout to 25 minutes.
The openTimeout
as the name implies is the amount of time you're willing to wait when you open the connection to your WCF service. Similarly, the closeTimeout
is the amount of time when you close the connection (dispose the client proxy) that you'll wait before an exception is thrown.
The receiveTimeout
is a bit like a mirror for the sendTimeout
- while the send timeout is the amount of time you'll wait for a response from the server, the receiveTimeout
is the amount of time you'll give you client to receive and process the response from the server.
In case you're send back and forth "normal" messages, both can be pretty short - especially the receiveTimeout
, since receiving a SOAP message, decrypting, checking and deserializing it should take almost no time. The story is different with streaming - in that case, you might need more time on the client to actually complete the "download" of the stream you get back from the server.
There's also openTimeout, receiveTimeout, and closeTimeout. The MSDN docs on binding gives you more information on what these are for.
To get a serious grip on all the intricasies of WCF, I would strongly recommend you purchase the "Learning WCF" book by Michele Leroux Bustamante:
and you also spend some time watching her 15-part "WCF Top to Bottom" screencast series - highly recommended!
For more advanced topics I recommend that you check out Juwal Lowy's Programming WCF Services book.
If you are using EBS, you can also try to mount the EBS Volume on a running instance. Then mount it on that running instance and see what's going on in /home. You can see things like is the user ubuntu or ec2-user ? or does it have the right public keys under ~/.ssh/authorized_keys
The Microsoft System.Interactive package has a version of Distinct that takes a key selector lambda. This is effectively the same as Jon Skeet's solution, but it may be helpful for people to know, and to check out the rest of the library.

In my experience you can rely on dkpg's exit codes.
The return code of dpkg -s is 0 if the package is installed and 1 if it's not, so the simplest solution I found was:
dpkg -s <pkg-name> 2>/dev/null >/dev/null || sudo apt-get -y install <pkg-name>
Works fine for me...
Check if sendmail is enabled, mostly if your server is provided by another company.

Now, let's say you are going to send it from a mailing list, that implements VERP (or some other bounce tracking mechanism that uses a different return-path). Lets say it will have a return-path of [email protected]
. The SMTP session might look like:
{S}220 workstation1 Microsoft ESMTP MAIL Service {C}HELO workstation1 {S}250 workstation1 Hello [127.0.0.1] {C}MAIL FROM:<[email protected]> {S}250 2.1.0 [email protected] OK {C}RCPT TO:<[email protected]> {S}250 2.1.5 [email protected] {C}DATA {S}354 Start mail input; end with <CRLF>.<CRLF> {C}From: <[email protected]> To: <[email protected]> Subject: Super simple email Reply-To: <[email protected]> This is a very simple body. . {S}250 Queued mail for delivery {C}QUIT {S}221 Service closing transmission channel
Where {C} and {S} represent Client and Server commands, respectively.
The recipient's mail would look like:
Return-Path: [email protected] From: <[email protected]> To: <[email protected]> Subject: Super simple email Reply-To: <[email protected]> This is a very simple body.
Now, let's describe the different "FROM"s.
MAIL FROM
command. As you can see, this does not need to be the same value that is found in the message headers. Only the recipient's mail server is supposed to add a Return-Path header to the top of the email. This records the actual Return-Path sender during the SMTP session. If a Return-Path header already exists in the message, then that header is removed and replaced by the recipient's mail server.All bounces that occur during the SMTP session should go back to the Return-Path address. Some servers may accept all email, and then queue it locally, until it has a free thread to deliver it to the recipient's mailbox. If the recipient doesn't exist, it should bounce it back to the recorded Return-Path value.
Note, not all mail servers obey this rule; Some mail servers will bounce it back to the FROM address.
The FROM address is the value found in the FROM header. This is supposed to be who the message is FROM. This is what you see as the "FROM" in most mail clients. If an email does not have a Reply-To header, then all human (mail client) replies should go back to the FROM address.
The Reply-To header is added by the sender (or the sender's software). It is where all human replies should be addressed too. Basically, when the user clicks "reply", the Reply-To value should be the value used as the recipient of the newly composed email. The Reply-To value should not be used by any server. It is meant for client-side (MUA) use only.
However, as you can tell, not all mail servers obey the RFC standards or recommendations.
Hopefully this should help clear things up. However, if I missed anything, let me know, and I'll try to answer.
This isn't on the code parter it's on the server side Contact your Server Manager or fix it from server if you own it If you use CPANEL/WHM GO TO WHM/SMTP RESTRICTIONS AND DISABLE IT
I know I'm joining late to the discussion, but I think this can be useful to others.
I wanted to avoid deprecated stuff and after a lot of fiddling I found a simple way to send to servers requiring Implicit SSL: use NuGet and add the MailKit package to the project. (I used VS2017 targetting .NET 4.6.2 but it should work on lower .NET versions...)
Then you'll only need to do something like this:
using MailKit.Net.Smtp;
using MimeKit;
var client = new SmtpClient();
client.Connect("server.name", 465, true);
// Note: since we don't have an OAuth2 token, disable the XOAUTH2 authentication mechanism.
client.AuthenticationMechanisms.Remove ("XOAUTH2");
if (needsUserAndPwd)
{
// Note: only needed if the SMTP server requires authentication
client.Authenticate (user, pwd);
}
var msg = new MimeMessage();
msg.From.Add(new MailboxAddress("[email protected]"));
msg.To .Add(new MailboxAddress("[email protected]"));
msg.Subject = "This is a test subject";
msg.Body = new TextPart("plain") {
Text = "This is a sample message body"
};
client.Send(msg);
client.Disconnect(true);
Of course you can also tweak it to use Explicit SSL or no transport security at all.
I'm not a WCF expert but I'm wondering if you aren't running into a DDOS protection on IIS. I know from experience that if you run a bunch of simultaneous connections from a single client to a server at some point the server stops responding to the calls as it suspects a DDOS attack. It will also hold the connections open until they time-out in order to slow the client down in his attacks.
Multiple connection coming from different machines/IP's should not be a problem however.
There's more info in this MSDN post:
http://msdn.microsoft.com/en-us/library/bb463275.aspx
Check out the MaxConcurrentSession sproperty.
In our case the problem was that we change the default root namespace name.
This is the Project Configuration screen
We finally decided to back to the original name and the problem was solved.
The problem actually was the dots in the Root namespace. With two dots (Name.Child.Child) it doesnt work. But with one (Name.ChidChild) works.
use my function as diagnostic certificates issues - see screen
System.Net.ServicePointManager.ServerCertificateValidationCallback = Function(s As Object,
cert As System.Security.Cryptography.X509Certificates.X509Certificate,
chain As System.Security.Cryptography.X509Certificates.X509Chain,
err As System.Net.Security.SslPolicyErrors)
Return True
End Function
Another option might be to avoid WCF all-together and just use a .NET HttpHandler. The HttpHandler can grab the query-string variables from your GET and just write back a response to the Java code.
Try this:
public class Person {
public int Id { get; set; }
public string Name { get; set; }
}
And then:
var list = new[] {
new Person { Id = 1, Name = "Name1" },
new Person { Id = 2, Name = "Name2" },
new Person { Id = 3, Name = "Name3" }
};
var selectList = new SelectList(list, "Id", "Name", 2);
ViewData["People"] = selectList;
Html.DropDownList("PeopleClass", (SelectList)ViewData["People"])
With MVC RC2, I get:
<select id="PeopleClass" name="PeopleClass">
<option value="1">Name1</option>
<option selected="selected" value="2">Name2</option>
<option value="3">Name3</option>
</select>
First, attempt to pull from the same refspec that you are trying to push to.
If this does not work, you can force a git push
by using git push -f <repo> <refspec>
, but use caution: this method can cause references to be deleted on the remote repository.
This won't do what you are expecting:
<img src="image1.gif" alt="image2.gif" />
The ALT attribute is text-only--it won't do anything special if you give it an image URL.
If you want to initially display a low res image, then replace it with a high res image, you could do some javascript coding to swap out the images. Or, perhaps load the image into a div which has a background pattern filled with the low res image. Then, when the high res image loads, it'll load overtop the background.
Unfortunately, there's no direct way to do this.
Your second attempt will create a link to image2, but actually display image1.
<a href="image2.gif" ><img src="image1.gif"/></a>
If you want to popup a higher res version, @Sam's suggestion is a good idea.
This CSS might work for you (it works for me in Firefox 3):
<html>
<head>
<style>
.lowres { background-image: url('low-res.png');}
</style>
</head>
<body>
<div class="lowres" style="height:500px; width:500px">
<img src="hi-res.png" />
</div>
</body>
</html>
In that example, you have to set the div height/width to that of the image. It will actually load both images simultaneously, but presuming the low-res one loads quick, you might see it first while the hi-res image downloads.
I think the problem can be because of the NAT. Normally the DNS clients make requests via UDP. But when the DNS server is behind the NAT the UDP requests will not work.
It largely depends on the library you decide to use. For instance, if you use the wxWidgets library, the creation of a thread would look like this:
class RThread : public wxThread {
public:
RThread()
: wxThread(wxTHREAD_JOINABLE){
}
private:
RThread(const RThread ©);
public:
void *Entry(void){
//Do...
return 0;
}
};
wxThread *CreateThread() {
//Create thread
wxThread *_hThread = new RThread();
//Start thread
_hThread->Create();
_hThread->Run();
return _hThread;
}
If your main thread calls the CreateThread method, you'll create a new thread that will start executing the code in your "Entry" method. You'll have to keep a reference to the thread in most cases to join or stop it. More info here: wxThread documentation
In Linux, you can start a process in a new independent thread by appending an ampersand at the end of the command
mycommand -someparam somevalue &
In Windows, you can use the "start" DOS command
start mycommand -someparam somevalue
The existing answers have quite broken code. The DNS method does not work at all. Here is code that I used to configure my NIC:

An IDE handles grunt work that saves you time.
It keeps all associated project files together which makes it easy to collaborate.
You can usually integrate your source control into your IDE saving more grunt work and further enhancing collaboration.
If it has auto complete features, it can help you explore your language of choice and also save some typing.
Basically, an IDE reduces non-programming work for the programmer.
Linux manual said:
EPIPE The local end has been shut down on a connection oriented socket. In this case the process will also receive a SIGPIPE unless MSG_NOSIGNAL is set.
But for Ubuntu 12.04 it isn't right. I wrote a test for that case and I always receive EPIPE withot SIGPIPE. SIGPIPE is genereated if I try to write to the same broken socket second time. So you don't need to ignore SIGPIPE if this signal happens it means logic error in your program.
Use data type long instead.. dont use int because it only allows whole numbers between -32,768 and 32,767 but if you use long data type you can insert numbers between -2,147,483,648 and 2,147,483,647.
What is the difference between exit(0)
and exit(1)
in C language?
exit(0)
indicates successful program termination & it is fully portable, While
exit(1)
(usually) indicates unsucessful termination. However, it's usage is non-portable.
Note that the C standard defines EXIT_SUCCESS
and EXIT_FAILURE
to return termination status from a C program.
0
and EXIT_SUCCESS
are the values specified by the standard to indicate successful termination, however, only EXIT_FAILURE
is the standard value for returning unsucessful termination. 1
is used for the same in many implementations though.
Reference:
C99 Standard: 7.20.4.3 The exit
function
Para 5
Finally, control is returned to the host environment. If the value of status is zero or
EXIT_SUCCESS
, an implementation-de?ned form of the status successful termination is returned. If the value of status isEXIT_FAILURE
, an implementation-de?ned form of the status unsuccessful termination is returned. Otherwise the status returned is implementation-de?ned.
Since your JPA repository name is UserBoardRepository, your custom Interface name should be UserBoardRepositoryCustom (it should end with 'Custom') and your implementation class name should be UserBoardRepositoryImpl (should end with Impl; you can set it with a different postfix using the repository-impl-postfix property)
Open the jenkins.xml
in the jenkins home folder (usually C:\Program Files (x86)\Jenkins
) and change the port number:
httpPort=xxxx
to
httpPort=yyyy
then restart the service. it should change the setting permanently.
By default link color is blue and the visited color is purple. Also, the text-decoration is underlined and the color is blue. If you want to keep the same color for visited, hover and focus then follow below code-
For example color is: #000
a:visited, a:hover, a:focus {
text-decoration: none;
color: #000;
}
If you want to use a different color for hover, visited and focus. For example Hover color: red visited color: green and focus color: yellow then follow below code
a:hover {
color: red;
}
a:visited {
color: green;
}
a:focus {
color: yellow;
}
NB: good practice is to use color code.
How can I validate if a String is null or empty using the c tags of JSTL?
You can use the empty
keyword in a <c:if>
for this:
<c:if test="${empty var1}">
var1 is empty or null.
</c:if>
<c:if test="${not empty var1}">
var1 is NOT empty or null.
</c:if>
Or the <c:choose>
:
<c:choose>
<c:when test="${empty var1}">
var1 is empty or null.
</c:when>
<c:otherwise>
var1 is NOT empty or null.
</c:otherwise>
</c:choose>
Or if you don't need to conditionally render a bunch of tags and thus you could only check it inside a tag attribute, then you can use the EL conditional operator ${condition? valueIfTrue : valueIfFalse}
:
<c:out value="${empty var1 ? 'var1 is empty or null' : 'var1 is NOT empty or null'}" />
To learn more about those ${}
things (the Expression Language, which is a separate subject from JSTL), check here.
You could specify what branch you want to pull:
git pull origin master
Or you could set it up so that your local master branch tracks github master branch as an upstream:
git branch --set-upstream-to=origin/master master
git pull
This branch tracking is set up for you automatically when you clone a repository (for the default branch only), but if you add a remote to an existing repository you have to set up the tracking yourself. Thankfully, the advice given by git makes that pretty easy to remember how to do.
For tasks of this type I usually use Crawller4j + Jsoup.
With crawler4j I download the pages from a domain, you can specify which ULR with a regular expression.
With jsoup, I "parsed" the html data you have searched for and downloaded with crawler4j.
Normally you can also download data with jsoup, but Crawler4J makes it easier to find links. Another advantage of using crawler4j is that it is multithreaded and you can configure the number of concurrent threads
You could use a negative look-ahead assertion:
^(?!tbd_).+
Or a negative look-behind assertion:
(^.{1,3}$|^.{4}(?<!tbd_).*)
Or just plain old character sets and alternations:
^([^t]|t($|[^b]|b($|[^d]|d($|[^_])))).*
I followed @LachlanB approach and indeed the session was available when the session cookie was present on the request. The missing part is how the Session cookie is sent to the client the first time?
I created a HttpModule which not only enabling the HttpSessionState availability but also sends the cookie to the client when a new session is created.
public class WebApiSessionModule : IHttpModule
{
private static readonly string SessionStateCookieName = "ASP.NET_SessionId";
public void Init(HttpApplication context)
{
context.PostAuthorizeRequest += this.OnPostAuthorizeRequest;
context.PostRequestHandlerExecute += this.PostRequestHandlerExecute;
}
public void Dispose()
{
}
protected virtual void OnPostAuthorizeRequest(object sender, EventArgs e)
{
HttpContext context = HttpContext.Current;
if (this.IsWebApiRequest(context))
{
context.SetSessionStateBehavior(SessionStateBehavior.Required);
}
}
protected virtual void PostRequestHandlerExecute(object sender, EventArgs e)
{
HttpContext context = HttpContext.Current;
if (this.IsWebApiRequest(context))
{
this.AddSessionCookieToResponseIfNeeded(context);
}
}
protected virtual void AddSessionCookieToResponseIfNeeded(HttpContext context)
{
HttpSessionState session = context.Session;
if (session == null)
{
// session not available
return;
}
if (!session.IsNewSession)
{
// it's safe to assume that the cookie was
// received as part of the request so there is
// no need to set it
return;
}
string cookieName = GetSessionCookieName();
HttpCookie cookie = context.Response.Cookies[cookieName];
if (cookie == null || cookie.Value != session.SessionID)
{
context.Response.Cookies.Remove(cookieName);
context.Response.Cookies.Add(new HttpCookie(cookieName, session.SessionID));
}
}
protected virtual string GetSessionCookieName()
{
var sessionStateSection = (SessionStateSection)ConfigurationManager.GetSection("system.web/sessionState");
return sessionStateSection != null && !string.IsNullOrWhiteSpace(sessionStateSection.CookieName) ? sessionStateSection.CookieName : SessionStateCookieName;
}
protected virtual bool IsWebApiRequest(HttpContext context)
{
string requestPath = context.Request.AppRelativeCurrentExecutionFilePath;
if (requestPath == null)
{
return false;
}
return requestPath.StartsWith(WebApiConfig.UrlPrefixRelative, StringComparison.InvariantCultureIgnoreCase);
}
}
Here my two cents, which permits casting up and down, and adds customizable precision:
def convertFloatToDecimal(f=0.0, precision=2):

'''

as final unit.

assert sizeIn.upper() in {"B", "KB", "MB", "GB"}, "sizeIn type error"
assert sizeOut.upper() in {"B", "KB", "MB", "GB"}, "sizeOut type error"
if sizeIn == "B":
if sizeOut == "KB":
return convertFloatToDecimal((size/1024.0), precision)

File extensions do not have any bearing or impact on the content of the file. You can hold YAML content in files with any extension: .yml
, .yaml
or indeed anything else.
The (rather sparse) YAML FAQ recommends that you use .yaml
in preference to .yml
, but for historic reasons many Windows programmers are still scared of using extensions with more than three characters and so opt to use .yml
instead.
So, what really matters is what is inside the file, rather than what its extension is.

This might be a simple solution to achieve this:
INSERT INTO funds (ID, date, price)
SELECT 23, DATE('2013-02-12'), 22.5
FROM dual
WHERE NOT EXISTS (SELECT 1
FROM funds
WHERE ID = 23
AND date = DATE('2013-02-12'));
p.s. alternatively (if ID
a primary key):
INSERT INTO funds (ID, date, price)
VALUES (23, DATE('2013-02-12'), 22.5)
ON DUPLICATE KEY UPDATE ID = 23; -- or whatever you need
see this Fiddle.
You can just do something like this and pass in the whole number and then the cents after.

I've just fixed such an issue on my laptop running windows 10. Suddenly wamp became super slow - a request to load a page was taking 2 minutes.
After trying numerous things, what it turned out to fix the problem was disabling windows defender. All worked like a charm after that.
p.s. I'd suggest you add your apache root dir to the exceptions list and not actually disable defender completely.
SSH based git access method can be specified in <repo_path>/.git/config
using either a full URL or an SCP-like syntax, as specified in http://git-scm.com/docs/git-clone:
URL style:
url = ssh://[user@]host.xz[:port]/path/to/repo.git/
SCP style:
url = [user@]host.xz:path/to/repo.git/
Notice that the SCP style does not allow a direct port change, relying instead on an ssh_config
host definition in your ~/.ssh/config
such as:
Host my_git_host
HostName git.some.host.org
Port 24589
User not_a_root_user
Then you can test in a shell with:
ssh my_git_host
and alter your SCP-style URI in <repo_path>/.git/config
as:
url = my_git_host:path/to/repo.git/

Ugliest interface possible, but does what you ask. Zero allocations.
http://zserge.com/jsmn.html Another zero-allocation approach.
The solutions posted above all do dynamic memory allocation, hence will be inevitably end up slower at some point, depending on the data structure - and will be dangerous to include in a heap constrained environment like an embedded system.
Benchmarks of vjson, rapidjson and sajson here : http://chadaustin.me/2013/01/json-parser-benchmarking/ if you are interested in that sort of thing.
And to answer your "writer" part of the question i doubt that you could beat an efficient
printf("{%s:%s}",name,value)
implementation with any library - assuming your printf/sprintf implementation itself is lightweight of course.
EDIT: actually let me take that back, RapidJson allows on-stack allocation only through its MemoryPoolAllocator and actually makes this a default for its GenericReader. I havent done the comparison but i would expect it to be more robust than anything else listed here. It also doesnt have any dependencies, and it doesnt throw exceptions which probably makes it ultimately suitable for embedded. Fully header based lib so, easy to include anywhere.

GWT Designer is very good and allows for rapid development of GWT websites. (http://www.instantiations.com/gwtdesigner/)
You can define more details by extending AbstractMongoConfiguration.
@Configuration
@EnableMongoRepositories("demo.mongo.model")
public class SpringMongoConfig extends AbstractMongoConfiguration {
@Value("${spring.profiles.active}")
private String profileActive;
@Value("${spring.application.name}")
private String proAppName;
@Value("${spring.data.mongodb.host}")
private String mongoHost;
@Value("${spring.data.mongodb.port}")
private String mongoPort;
@Value("${spring.data.mongodb.database}")
private String mongoDB;
@Override
public MongoMappingContext mongoMappingContext()
throws ClassNotFoundException {
// TODO Auto-generated method stub
return super.mongoMappingContext();
}
@Override
@Bean
public Mongo mongo() throws Exception {
return new MongoClient(mongoHost + ":" + mongoPort);
}
@Override
protected String getDatabaseName() {
// TODO Auto-generated method stub
return mongoDB;
}
}
In your 'encrypt' method, you should either get rid of the try/catch and instead add a try/catch around where you call encrypt (inside 'actionPerformed') or return null inside the catch within encrypt (that's the second error.
As MySql accepts the date in y-m-d format in date type column, you need to STR_TO_DATE
function to convert the date into yyyy-mm-dd format for insertion in following way:
INSERT INTO table_name(today)
VALUES(STR_TO_DATE('07-25-2012','%m-%d-%y'));
Similary, if you want to select the date in different format other than Mysql format, you should try DATE_FORMAT
function
SELECT DATE_FORMAT(today, '%m-%d-%y') from table_name;
Thanks for enlightening us Cypawer.
I also tried this app https://play.google.com/store/apps/details?id=com.oneguyinabasement.leapwifi
and it worked flawlessly.
The curly braces inside backgroundImage property are wrong.
Probably you are using webpack along with image files loader, so Background should be already a String:
backgroundImage: "url(" + Background + ")"
You can also use ES6 string templates as below to achieve the same effect:
backgroundImage: `url(${Background})`
It'll be easier (and more "proper", see below) if you just run your script as
myprogram /path/to/file
Then you can access the path within the script as $1
(for argument #1, similarly $2
is argument #2, etc.)
file="$1"
externalprogram "$file" [other parameters]
Or just
externalprogram "$1" [otherparameters]
If you want to extract the path from something like --file=/path/to/file
, that's usually done with the getopts
shell function. But that's more complicated than just referencing $1
, and besides, switches like --file=
are intended to be optional. I'm guessing your script requires a file name to be provided, so it doesn't make sense to pass it in an option.
Alpine uses the command adduser
and addgroup
for creating users and groups (rather than useradd
and usergroup
).
FROM alpine:latest
# Create a group and user
RUN addgroup -S appgroup && adduser -S appuser -G appgroup
# Tell docker that all future commands should run as the appuser user
USER appuser
The flags for adduser
are:
Usage: adduser [OPTIONS] USER [GROUP] Create new user, or add USER to GROUP -h DIR Home directory -g GECOS GECOS field -s SHELL Login shell -G GRP Group -S Create a system user -D Don't assign a password -H Don't create home directory -u UID User id -k SKEL Skeleton directory (/etc/skel)
Another approach is to set the axis locator:
import matplotlib.ticker as plticker
loc = plticker.MultipleLocator(base=1.0) # this locator puts ticks at regular intervals
ax.xaxis.set_major_locator(loc)
There are several different types of locator depending upon your needs.
Here is a full example:
import matplotlib.pyplot as plt
import matplotlib.ticker as plticker
x = [0,5,9,10,15]
y = [0,1,2,3,4]
fig, ax = plt.subplots()
ax.plot(x,y)
loc = plticker.MultipleLocator(base=1.0) # this locator puts ticks at regular intervals
ax.xaxis.set_major_locator(loc)
plt.show()
There's one big difference between CLOCK_REALTIME and MONOTONIC. CLOCK_REALTIME can jump forward or backward according to NTP. By default, NTP allows the clock rate to be speeded up or slowed down by up to 0.05%, but NTP cannot cause the monotonic clock to jump forward or backward.
You cannot do so - the browser will not allow this because of security concerns. Although there are workarounds, the fact is that you shouldn't count on this working. The following Stack Overflow questions are relevant here:
In addition to these, the new HTML5 specification states that browsers will need to feed a Windows compatible fakepath into the input type="file"
field, ostensibly for backward compatibility reasons.
So trying to obtain the path is worse then useless in newer browsers - you'll actually get a fake one instead.
Just tried this solution, we don't have to even write int.
int[][] twoDim = { { 1, 2 }, { 3, 7 }, { 8, 9 }, { 4, 2 }, { 5, 3 } };
Arrays.sort(twoDim, (a1,a2) -> a2[0] - a1[0]);
This thing will also work, it automatically detects the type of string.
I recently started playing with MQTT http://mqtt.org for Android as a way of doing what you're asking for (i.e. not SMS but data driven, almost immediate message delivery, scalable, not polling, etc.)
I have a blog post with background information on this in case it's helpful http://dalelane.co.uk/blog/?p=938
(Note: MQTT is an IBM technology, and I should point out that I work for IBM.)
Except char
, every other numerical data type in Java are signed.
As said in a previous answer, you can get the unsigned value by performing an and
operation with 0xFF
. In this answer, I'm going to explain how it happens.
int i = 234;
byte b = (byte) i;
System.out.println(b); // -22
int i2 = b & 0xFF;
// This is like casting b to int and perform and operation with 0xFF
System.out.println(i2); // 234
If your machine is 32-bit, then the int
data type needs 32-bits to store values. byte
needs only 8-bits.
The int
variable i
is represented in the memory as follows (as a 32-bit integer).
0{24}11101010
Then the byte
variable b
is represented as:
11101010
As byte
s are unsigned, this value represent -22
. (Search for 2's complement to learn more on how to represent negative integers in memory)
Then if you cast is to int
it will still be -22
because casting preserves the sign of a number.
1{24}11101010
The the casted 32-bit
value of b
perform and
operation with 0xFF
.
1{24}11101010 & 0{24}11111111
=0{24}11101010
Then you get 234
as the answer.
For anyone using a Form request
In my case i tried all of the following none of them worked:
$this->id
, $this->user->id
, $this->user
.
It was because i could not access the model $id
nor the $id
directly.
So i got the $id
from a query using the same unique
field i am trying to validate:
/**
* Get the validation rules that apply to the request.
*
* @return array
*/
public function rules()
{
$id = YourModel::where('unique_field',$this->request->get('unique_field'))->value('id');
return [
'unique_field' => ['rule1','rule2',Rule::unique('yourTable')->ignore($id)],
];
}
A C solution.
int two(int a, int b, int c) {
return !a + !b + !c < 2;
}
or you may prefer:
int two(int a, int b, int c) {
return !!a + !!b + !!c >= 2;
}
This link can help you: http://www.scriptol.com/html5/combobox.php
You have two examples. One in html4 and other in html5
HTML5
<input type="text" list="browsers"/>
<datalist id="browsers">

function combo(thelist, theinput) {
theinput = document.getElementById(theinput);
var idx = thelist.selectedIndex;
var content = thelist.options[idx].innerHTML;
theinput.value = content;

It depends on your project structure. But most straightforward is:
go build -o ./myproject ./...
then run ./myproject
.
Suppose your project structure looks like this
- hello
|- main.go
then you just go to the project directory and run
go build -o ./myproject
then run ./myproject
on shell.
or
# most easiest; builds and run simultaneously
go run main.go
suppose your main file is nested into a sub-directory like a cmd
- hello
|- cmd
|- main.go
then you will run
go run cmd/main.go
\mbox
is the simplest answer. Regarding the update:
TeX prefers overlong lines to adding too much space between words on a line; I think the idea is that you will notice the lines that extend into the margin (and the black boxes it inserts after such lines), and will have a chance to revise the contents, whereas if there was too much space, you might not notice it.
Use \sloppy
or \begin{sloppypar}...\end{sloppypar}
to adjust this behavior, at least a little. Another possibility is \raggedright
(or \begin{raggedright}...\end{raggedright}
).
- Each time you append or do any modification with it, it creates a new String
object.
- So use append()
method of StringBuilder
(If thread safety is not important), else use StringBuffer
(If thread safety is important.), that will be efficient way to do it.
There can only be one Access-Control-Allow-Origin
response header, and that header can only have one origin value. Therefore, in order to get this to work, you need to have some code that:
Origin
request header.Access-Control-Allow-Origin
header with that value.I don't think there's any way to do this solely through the web.config.
if (ValidateRequest()) {
Response.Headers.Remove("Access-Control-Allow-Origin");
Response.AddHeader("Access-Control-Allow-Origin", Request.UrlReferrer.GetLeftPart(UriPartial.Authority));
Response.Headers.Remove("Access-Control-Allow-Credentials");
Response.AddHeader("Access-Control-Allow-Credentials", "true");
Response.Headers.Remove("Access-Control-Allow-Methods");
Response.AddHeader("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS");
}
As an addition to @ANisus' answer...
below is some information from the "Go in action" book, which I think is worth mentioning:
nil
& empty
slicesIf we think of a slice like this:
[pointer] [length] [capacity]
then:
nil slice: [nil][0][0]
empty slice: [addr][0][0] // points to an address
nil slice
They’re useful when you want to represent a slice that doesn’t exist, such as when an exception occurs in a function that returns a slice.
// Create a nil slice of integers. var slice []int
empty slice
Empty slices are useful when you want to represent an empty collection, such as when a database query returns zero results.
// Use make to create an empty slice of integers. slice := make([]int, 0) // Use a slice literal to create an empty slice of integers. slice := []int{}
Regardless of whether you’re using a nil slice or an empty slice, the built-in functions
append
,len
, andcap
work the same.
package main
import (
"fmt"
)
func main() {
var nil_slice []int
var empty_slice = []int{}
fmt.Println(nil_slice == nil, len(nil_slice), cap(nil_slice))
fmt.Println(empty_slice == nil, len(empty_slice), cap(empty_slice))
}
prints:
true 0 0
false 0 0
If you are running postgresql on mac os, try these:
Edit the pg_hba.conf file
sudo vi /Library/PostgreSQL/9.2/data/pg_hba.conf
Change the "md5" method for all users to "trust" near the bottom of the file
Find the name of the service
ls /Library/LaunchDaemons
Look for postgresql
Stop the postgresql service
sudo launchctl stop com.edb.launchd.postgresql-9.2
Start the postgresql service
sudo launchctl start com.edb.launchd.postgresql-9.2
Start psql session as postgres
psql -U postgres
(shouldn't ask for password because of 'trust' setting)
Reset password in psql session by typing
ALTER USER postgres with password 'secure-new-password';
enter
Edit the pg_hba.conf file
Switch it back to 'md5'
Restart services again
You are probably behind a firewall. Try cloning via https – that has a higher chance of not being blocked:

Good cocoa function:
-(BOOL) NSStringIsValidEmail:(NSString *)checkString
{
BOOL stricterFilter = NO; // Discussion http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/
NSString *stricterFilterString = @"^[A-Z0-9a-z\\._%+-]+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2,4}$";
NSString *laxString = @"^.+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2}[A-Za-z]*$";
NSString *emailRegex = stricterFilter ? stricterFilterString : laxString;
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
return [emailTest evaluateWithObject:checkString];
}
Discussion on Lax vs. Strict - http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/
And because categories are just better, you could also add an interface:
@interface NSString (emailValidation)
- (BOOL)isValidEmail;
@end
Implement
@implementation NSString (emailValidation)
-(BOOL)isValidEmail
{
BOOL stricterFilter = NO; // Discussion http://blog.logichigh.com/2010/09/02/validating-an-e-mail-address/
NSString *stricterFilterString = @"^[A-Z0-9a-z\\._%+-]+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2,4}$";
NSString *laxString = @"^.+@([A-Za-z0-9-]+\\.)+[A-Za-z]{2}[A-Za-z]*$";
NSString *emailRegex = stricterFilter ? stricterFilterString : laxString;
NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];
return [emailTest evaluateWithObject:self];
}
@end
And then utilize:
if([@"[email protected]" isValidEmail]) { /* True */ }
if([@"InvalidEmail@notreallyemailbecausenosuffix" isValidEmail]) { /* False */ }
There are two ways to change the dialog button color.
Basic Way
If you just want to change in an activity, write the below two lines after alertDialog.show();
alertDialog.getButton(AlertDialog.BUTTON_POSITIVE).setTextColor(getResources().getColor(R.color.colorPrimary));
alertDialog.getButton(AlertDialog.BUTTON_NEGATIVE).setTextColor(getResources().getColor(R.color.colorPrimaryDark));
Recommended
I'll recommend adding a theme for AlertDialog
in styles.xml
so you don't have to write the same code again and again in each activity/dialog call. You can just create a style and apply that theme on the dialog box. So whenever you want to change the color of AlertDialog box, just change color in styles.xml and all the dialog boxes will be updated in the whole application.
<style name="AlertDialogTheme" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="colorAccent">@color/colorPrimary</item>
</style>
And apply the theme in AlertDialog.Builder
AlertDialog.Builder builder = new AlertDialog.Builder(this, R.style.AlertDialogTheme);
You can use a very good online tool for it. Here is the link dreampuf.github.io Just replace the code inside editer with your code.
getActivity()- Return the Activity this fragment is currently associated with.
I had a similar problem for the preview Web API. Did not port that part to the new MVC 4 Web API yet, but maybe this helps:
REST file upload with HttpRequestMessage or Stream?
Please let me know, can sit down tomorrow and try to implement it again.
You can either:
pre { white-space: normal; }
to maintain the monospace font but add word-wrap, or:
pre { overflow: auto; }
which will allow a fixed size with horizontal scrolling for long lines.
I'm making the following assumptions with this function:
This should be treated as a demonstration of a simple strategy.
/**
* Checks the equality of two objects that contain primitive values. (ie. no nested objects, functions, etc.)
* @param {Object} object1
* @param {Object} object2
* @param {Boolean} [order_matters] Affects the return value of unordered objects. (ex. {a:1, b:2} and {b:2, a:1}).
* @returns {Boolean}
*/
function isEqual( object1, object2, order_matters ) {
var keys1 = Object.keys(object1),
keys2 = Object.keys(object2),
i, key;
// Test 1: Same number of elements
if( keys1.length != keys2.length ) {
return false;
}
// If order doesn't matter isEqual({a:2, b:1}, {b:1, a:2}) should return true.
// keys1 = Object.keys({a:2, b:1}) = ["a","b"];
// keys2 = Object.keys({b:1, a:2}) = ["b","a"];
// This is why we are sorting keys1 and keys2.
if( !order_matters ) {
keys1.sort();
keys2.sort();
}
// Test 2: Same keys
for( i = 0; i < keys1.length; i++ ) {
if( keys1[i] != keys2[i] ) {
return false;
}
}
// Test 3: Values
for( i = 0; i < keys1.length; i++ ) {
key = keys1[i];
if( object1[key] != object2[key] ) {
return false;
}
}
return true;
}
For excluding one or more library globally add the following to your build.gradle
configurations.all {
exclude group:"org.apache.geronimo.specs", module: "geronimo-servlet_2.5_spec"
exclude group:"ch.qos.logback", module:"logback-core"
}
Now the exclude block has two properties group and module. For those of you coming from maven background, group is same as groupId and module is same as artifactId. Example: To exclude com.mchange:c3p0:0.9.2.1 following should be exclude block
exclude group:"com.mchange", module:"c3p0"
you have three ways to enable CORS:
Enable CORS with named policy:
public class Startup
{
readonly string CorsPolicy = "_corsPolicy";
public void ConfigureServices(IServiceCollection services)
{
services.AddCors(options =>
{
options.AddPolicy(name: CorsPolicy,
builder =>
{
builder.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader()
.AllowCredentials();
});
});
// services.AddResponseCaching();
services.AddControllers();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
app.UseRouting();
app.UseCors(CorsPolicy);
// app.UseResponseCaching();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
}
}
UseCors must be called before UseResponseCaching when using UseResponseCaching.
Enable CORS with default policy:
public class Startup
{
public void ConfigureServices(IServiceCollection services)
{
services.AddCors(options =>
{
options.AddDefaultPolicy(
builder =>
{
builder.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader()
.AllowCredentials();
});
});
services.AddControllers();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
app.UseRouting();
app.UseCors();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
}
}
Enable CORS with endpoint
public class Startup
{
readonly string CorsPolicy = "_corsPolicy ";
public void ConfigureServices(IServiceCollection services)
{
services.AddCors(options =>
{
options.AddPolicy(name: CorsPolicy,
builder =>
{
builder.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader()
.AllowCredentials();
});
});
services.AddControllers();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
app.UseRouting();
app.UseCors();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers()
.RequireCors(CorsPolicy)
});
}
}
Enable CORS with attributes
you have tow option
First I recommend you as @ChrisHuang-Leaver suggested to define a new file with all the choices you need it there, like choices.py
:
STATUS_CHOICES = (
(1, _("Not relevant")),
(2, _("Review")),
(3, _("Maybe relevant")),
(4, _("Relevant")),
(5, _("Leading candidate"))
)
RELEVANCE_CHOICES = (
(1, _("Unread")),
(2, _("Read"))
)
Now you need to import them on the models, so the code is easy to understand like this(models.py):
from myApp.choices import *
class Profile(models.Model):
user = models.OneToOneField(User)
status = models.IntegerField(choices=STATUS_CHOICES, default=1)
relevance = models.IntegerField(choices=RELEVANCE_CHOICES, default=1)
And you have to import the choices in the forms.py too:
forms.py:
from myApp.choices import *
class CViewerForm(forms.Form):
status = forms.ChoiceField(choices = STATUS_CHOICES, label="", initial='', widget=forms.Select(), required=True)
relevance = forms.ChoiceField(choices = RELEVANCE_CHOICES, required=True)
Anyway you have an issue with your template, because you're not using any {{form.field}}
, you generate a table but there is no inputs only hidden_fields.
When the user is staff you should generate as many input fields as users you can manage. I think django form is not the best solution for your situation.
I think it will be better for you to use html form, so you can generate as many inputs using the boucle: {% for user in users_list %}
and you generate input with an ID related to the user, and you can manage all of them in the view.
You have conditions that are mutually exclusive - if meta_key is 'first_name', it can't also be 'yearofpassing'. Most likely you need your AND's to be OR's:
$result = mysql_query("SELECT user_id FROM wp_usermeta
WHERE (meta_key = 'first_name' AND meta_value = '$us_name')
OR (meta_key = 'yearofpassing' AND meta_value = '$us_yearselect')
OR (meta_key = 'u_city' AND meta_value = '$us_reg')
OR (meta_key = 'us_course' AND meta_value = '$us_course')")
Although I was expecting an automatic solution (fitting to the screen automatically), resizing solves the problem as well.
import cv2
cv2.namedWindow("output", cv2.WINDOW_NORMAL) # Create window with freedom of dimensions
im = cv2.imread("earth.jpg") # Read image
imS = cv2.resize(im, (960, 540)) # Resize image
cv2.imshow("output", imS) # Show image
cv2.waitKey(0) # Display the image infinitely until any keypress
Try using GET method,
var request = $.ajax({
url: 'url',
type: 'GET',
data: { field1: "hello", field2 : "hello2"} ,
contentType: 'application/json; charset=utf-8'
});
request.done(function(data) {
// your success code here
});
request.fail(function(jqXHR, textStatus) {
// your failure code here
});
You cannot see parameters in URL with POST method.
Edit:
Deprecation Notice: The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callbacks are removed as of jQuery 3.0. You can use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.
If you put the username and password at clientside into the request this way:
URL url = new URL("http://localhost:8080/myapplication?wsdl");
MyWebService webservice = new MyWebServiceImplService(url).getMyWebServiceImplPort();
Map<String, Object> requestContext = ((BindingProvider) webservice).getRequestContext();
requestContext.put(BindingProvider.USERNAME_PROPERTY, "myusername");
requestContext.put(BindingProvider.PASSWORD_PROPERTY, "mypassword");
and call your webservice
String response = webservice.someMethodAtMyWebservice("test");
Then you can read the Basic Authentication string like this at the server side (you have to add some checks and do some exceptionhandling):
@Resource
WebServiceContext webserviceContext;
public void someMethodAtMyWebservice(String parameter) {
MessageContext messageContext = webserviceContext.getMessageContext();
Map<String, ?> httpRequestHeaders = (Map<String, ?>) messageContext.get(MessageContext.HTTP_REQUEST_HEADERS);
List<?> authorizationList = (List<?>) httpRequestHeaders.get("Authorization");
if (authorizationList != null && !authorizationList.isEmpty()) {
String basicString = (String) authorizationList.get(0);
String encodedBasicString = basicString.substring("Basic ".length());
String decoded = new String(Base64.getDecoder().decode(encodedBasicString), StandardCharsets.UTF_8);
String[] splitter = decoded.split(":");
String usernameFromBasicAuth = splitter[0];
String passwordFromBasicAuth = splitter[1];
}

O.K. I neither have rep to comment on previous answer (of Philippe De Muyter) nor raise it's score, hence a new example using his define for SIGNED_MAX trivially extended for unsigned types:
// We can use it to define limits based on actual compiler built-in types also:
#define INT_MAX SIGNED_MAX(int)
// based on the above, we can extend it for unsigned types also:
#define UNSIGNED_MAX(x) ( (SIGNED_MAX(x)<<1) | 1 ) // We reuse SIGNED_MAX
#define UINT_MAX UNSIGNED_MAX(unsigned int) // on ARM: 4294967295
// then we can have:
unsigned int width = UINT_MAX;
Unlike using this or that header, here we use the real type from the compiler.

Modified from the recipes section of Python's itertools docs:
from itertools import zip_longest
def grouper(iterable, n, fillvalue=None):
args = [iter(iterable)] * n
return zip_longest(*args, fillvalue=fillvalue)
Example
In pseudocode to keep the example terse.
grouper('ABCDEFG', 3, 'x') --> 'ABC' 'DEF' 'Gxx'
Note: on Python 2 use izip_longest
instead of zip_longest
.

I used Castle dynamic proxy to solve the Dispose() issue, and also implemented auto-refreshing the channel when it is in an unusable state. To use this you must create a new interface that inherits your service contract and IDisposable. The dynamic proxy implements this interface and wraps a WCF channel:
Func<object> createChannel = () =>
ChannelFactory<IHelloWorldService>
.CreateChannel(new NetTcpBinding(), new EndpointAddress(uri));
var factory = new WcfProxyFactory();
var proxy = factory.Create<IDisposableHelloWorldService>(createChannel);
proxy.HelloWorld();
I like this since you can inject WCF services without consumers needing to worry about any details of WCF. And there's no added cruft like the other solutions.
Have a look at the code, it's actually pretty simple: WCF Dynamic Proxy
What about::
pip install --help

-e, --editable <path/url> Install a project in editable mode (i.e. setuptools
"develop mode") from a local project path or a VCS url.
eg, pip install -e /srv/pkg
where /srv/pkg is the top-level directory where 'setup.py' can be found.
Important to mention:
On the commandline you can't use
svn add *
This will also add the ignored files, because the command line expands *
and therefore svn add
believes that you want all files to be added. Therefore use this instead:
svn add --force .
It turns out that you can create 32-bit ODBC connections using C:\Windows\SysWOW64\odbcad32.exe
. My solution was to create the 32-bit ODBC connection as a System DSN. This still didn't allow me to connect to it since .NET couldn't look it up. After significant and fruitless searching to find how to get the OdbcConnection class to look for the DSN in the right place, I stumbled upon a web site that suggested modifying the registry to solve a different problem.
I ended up creating the ODBC connection directly under HKLM\Software\ODBC
. I looked in the SysWOW6432 key to find the parameters that were set up using the 32-bit version of the ODBC administration tool and recreated this in the standard location. I didn't add an entry for the driver, however, as that was not installed by the standard installer for the app either.
After creating the entry (by hand), I fired up my windows service and everything was happy.

Thanks, I didn't have the idea of an UPDATE with INNER JOIN.
In the original query, the mistake was to name the subquery, which must return a value and can't therefore be aliased.
UPDATE Competition
SET Competition.NumberOfTeams =
(SELECT count(*) -- no column alias
FROM PicksPoints
WHERE UserCompetitionID is not NULL
-- put the join condition INSIDE the subquery :
AND CompetitionID = Competition.CompetitionID
group by CompetitionID
) -- no table alias
should do the trick for every record of Competition.
To be noticed :
The effect is NOT EXACTLY the same as the query proposed by mellamokb, which won't update Competition records with no corresponding PickPoints.
Since SELECT id, COUNT(*) GROUP BY id
will only count for existing values of ids,
whereas a SELECT COUNT(*)
will always return a value, being 0 if no records are selected.
This may, or may not, be a problem for you.
0-aware version of mellamokb query would be :
Update Competition as C
LEFT join (
select CompetitionId, count(*) as NumberOfTeams
from PicksPoints as p
where UserCompetitionID is not NULL
group by CompetitionID
) as A on C.CompetitionID = A.CompetitionID
set C.NumberOfTeams = IFNULL(A.NumberOfTeams, 0)
In other words, if no corresponding PickPoints are found, set Competition.NumberOfTeams to zero.

You can use the following code:
public static void main(String[] args) {
capitalizeFirstLetter("java");
capitalizeFirstLetter("java developer");
}
public static void capitalizeFirstLetter(String text) {
StringBuilder str = new StringBuilder();
String[] tokens = text.split("\\s");// Can be space,comma or hyphen
for (String token : tokens) {
str.append(Character.toUpperCase(token.charAt(0))).append(token.substring(1)).append(" ");
}
str.toString().trim(); // Trim trailing space
System.out.println(str);
}
You can do something like this:
div {_x000D_
display: none;_x000D_
}_x000D_
_x000D_
a:hover + div {_x000D_
display: block;_x000D_
}
_x000D_
<a>Hover over me!</a>_x000D_
<div>Stuff shown on hover</div>
_x000D_
This uses the adjacent sibling selector, and is the basis of the suckerfish dropdown menu.
HTML5 allows anchor elements to wrap almost anything, so in that case the div
element can be made a child of the anchor. Otherwise the principle is the same - use the :hover
pseudo-class to change the display
property of another element.
Here is how i resolved this:
1 - create a Field Variable like: private Menu mMenuItem;
2 - override the method invalidateOptionsMenu():
@Override
public void invalidateOptionsMenu() {
super.invalidateOptionsMenu();
}
3 - call the method invalidateOptionsMenu()
in your onCreate()
4 - add mMenuItem = menu
in your onCreateOptionsMenu(Menu menu)
like this:
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.webview_menu, menu);
mMenuItem = menu;
return super.onCreateOptionsMenu(menu);
}
5 - in the method onOptionsItemSelected(MenuItem item)
change the icon you want like this:
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()){
case R.id.R.id.action_settings:
mMenuItem.getItem(0).setIcon(R.drawable.ic_launcher); // to change the fav icon
//Toast.makeText(this, " " + mMenuItem.getItem(0).getTitle(), Toast.LENGTH_SHORT).show(); <<--- this to check if the item in the index 0 is the one you are looking for
return true;
}
return super.onOptionsItemSelected(item);
}
In order to comply with boneheaded precedent, getYear()
returns the number of years since 1900.
Instead, you should call getFullYear()
, which returns the actual year.
In your example, it’s fine as it is: it’s simple and works. The only things I’d suggest are:
make sure your API is sending the Content-Type
header to tell the client to expect a JSON response:
header('Content-Type: application/json');
echo json_encode($response);
Other than that, an API is something that takes an input and provides an output. It’s possible to “over-engineer” things, in that you make things more complicated that need be.
If you wanted to go down the route of controllers and models, then read up on the MVC pattern and work out how your domain objects fit into it. Looking at the above example, I can see maybe a MathController
with an add()
action/method.
There are a few starting point projects for RESTful APIs on GitHub that are worth a look.
On OSX, the command will depend on the flavour of python installation you have.
Python 2.x - Default
sudo pip install requests
Python 3.x
sudo pip3 install requests
Using the win32 API it is possible to "eat" another application. Basically you get the top window for that application and set it's parent to be the handle of the panel you want to place it in. If you don't want the MDI style effect you also have to adjust the window style to make it maximised and remove the title bar.
Here is some simple sample code where I have a form with a button and a panel:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Diagnostics;
using System.Runtime.InteropServices;
using System.Threading;
namespace WindowsFormsApplication2
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void button1_Click(object sender, EventArgs e)
{
Process p = Process.Start("notepad.exe");
Thread.Sleep(500); // Allow the process to open it's window
SetParent(p.MainWindowHandle, panel1.Handle);
}
[DllImport("user32.dll")]
static extern IntPtr SetParent(IntPtr hWndChild, IntPtr hWndNewParent);
}
}
I just saw another example where they called WaitForInputIdle instead of sleeping. So the code would be like this:
Process p = Process.Start("notepad.exe");
p.WaitForInputIdle();
SetParent(p.MainWindowHandle, panel1.Handle);
The Code Project has a good article one the whole process: Hosting EXE Applications in a WinForm project
Your print
is messing things up, because it resets @@ROWCOUNT
. Whenever you use @@ROWCOUNT
, my advice is to always set it immediately to a variable. So:
DECLARE @RC int;
WHILE @RC > 0 or @RC IS NULL
BEGIN
SET rowcount 5;
UPDATE TableName
SET Value = 'abc1'
WHERE Parameter1 = 'abc' AND Parameter2 = 123 AND Value <> 'abc1';
SET @RC = @@ROWCOUNT;
PRINT(@@ROWCOUNT)
END;
SET rowcount = 0;
And, another nice feature is that you don't need to repeat the update
code.
As others have mentioned, from C++17 onwards you can make use of structured bindings for multiple variable assignments.
Combining this with std::array
and template argument deduction we can write a function that assigns a value to an arbitrary number of variables without repeating the type or value.
#include <iostream>
#include <array>
template <int N, typename T> auto assign(T value)
{
std::array<T, N> out;
out.fill(value);
return out;
}
int main()
{
auto [a, b, c] = assign<3>(1);
for (const auto& v : {a, b, c})
{
std::cout << v << std::endl;
}
return 0;
}
I had the same problem. I changed the order of the scripts in the head part, and it worked for me. Every script the plugin needs - needs to stay close.
For example:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js"></script>
<script type="text/javascript" src="http://cloud.github.com/downloads/malsup/cycle/jquery.cycle.all.latest.js"></script>
<script type="text/javascript">
$(document).ready(function() {
$('#slider').cycle({
fx: 'fade'
});
});
</script>

The hint (using axfr) only works if the NS you're querying (ns1.foo.bar in your example) is configured to allow AXFR requests from the IP you're using; this is unlikely, unless your IP is configured as a secondary for the domain in question.
Basically, there's no easy way to do it if you're not allowed to use axfr. This is intentional, so the only way around it would be via brute force (i.e. dig a.some_domain.com
, dig b.some_domain.com
, ...), which I can't recommend, as it could be viewed as a denial of service attack.
This is now possible with C# 7.0's pattern matching. For example:
var myString = "abcDEF";
switch(myString)
{
case string x when x.StartsWith("abc"):
//Do something here
break;
}
var str = 'asd-0.testing';
var regex = /(asd-)\d(\.\w+)/;
str = str.replace(regex, "$11$2");
console.log(str);
Or if you're sure there won't be any other digits in the string:
var str = 'asd-0.testing';
var regex = /\d/;
str = str.replace(regex, "1");
console.log(str);
$_SERVER['SERVER_NAME'] is based on your web servers configuration. $_SERVER['HTTP_HOST'] is based on the request from the client.
I found it very useful to build also a json message with repeated code, like this:
@POST
@Consumes("application/json")
@Produces("application/json")
public Response authUser(JsonObject authData) {
String email = authData.getString("email");
String password = authData.getString("password");
JSONObject json = new JSONObject();
if (email.equalsIgnoreCase(user.getEmail()) && password.equalsIgnoreCase(user.getPassword())) {
json.put("status", "success");
json.put("code", Response.Status.OK.getStatusCode());
json.put("message", "User " + authData.getString("email") + " authenticated.");
return Response.ok(json.toString()).build();
} else {
json.put("status", "error");
json.put("code", Response.Status.NOT_FOUND.getStatusCode());
json.put("message", "User " + authData.getString("email") + " not found.");
return Response.status(Response.Status.NOT_FOUND).entity(json.toString()).build();
}
}
The RestTemplate getForObject()
method does not support setting headers. The solution is to use the exchange()
method.
So instead of restTemplate.getForObject(url, String.class, param)
(which has no headers), use
HttpHeaders headers = new HttpHeaders();
headers.set("Header", "value");
headers.set("Other-Header", "othervalue");
...
HttpEntity entity = new HttpEntity(headers);
ResponseEntity<String> response = restTemplate.exchange(
url, HttpMethod.GET, entity, String.class, param);
Finally, use response.getBody()
to get your result.
This question is similar to this question.
You can change the listen port as per your requirement. This task can be accomplished in two diffrent ways. By changing config.xml file By changing in admin console Change the listen port in config.xml as per your requirement and bounce the domain. Admin Console Login to AdminConsole->Server->Configuration->ListenPort (Change it) Note: It is a bad practice to edit config.xml and try to edit in admin console(It's a good practise as well)
My version without a loop would be like this:

array_map(
function ($k, $v) {
return "$k is at $v";
},
array_keys($page),
array_values($page)
)
);

It's the remainder operator and is used to get the remainder after integer division. Lots of languages have it. For example:
10 % 3 // = 1 ; because 3 * 3 gets you 9, and 10 - 9 is 1.
Apparently it is not the same as the modulo operator entirely.
Whenever I need an "instant data object that also behaves like a dictionary" (I don't think of C structs!), I think of this cute hack:
class Map(dict):
def __init__(self, **kwargs):
super(Map, self).__init__(**kwargs)
self.__dict__ = self
Now you can just say:
struct = Map(field1='foo', field2='bar', field3=42)
self.assertEquals('bar', struct.field2)
self.assertEquals(42, struct['field3'])
Perfectly handy for those times when you need a "data bag that's NOT a class", and for when namedtuples are incomprehensible...
You can use as following.
$start_date = date('Y-m-d H:i:s');
$end_date = date("Y-m-d 23:59:59", strtotime('+3 days', strtotime($start_date)));
You can also set days as constant and use like below.
if (!defined('ADD_DAYS')) define('ADD_DAYS','+3 days');
$end_date = date("Y-m-d 23:59:59", strtotime(ADD_DAYS, strtotime($start_date)));

Because it makes these things so easy, you could consider using a JavaScript library like jQuery to do this:
<script>
$(document).ready(function() {
$('img.thumbnail').click(function() {
window.location.href = this.id + '.html';
});
});
</script>
Basically, it attaches an onClick
event to all images with class thumbnail
to redirect to the corresponding HTML page (id
+ .html
). Then you only need the images in your HTML (without the a
elements), like this:
<img src="bottle.jpg" alt="bottle" class="thumbnail" id="bottle" />
<img src="glass.jpg" alt="glass" class="thumbnail" id="glass" />
This may be helpful if you have more than one python versions installed and dont know how to tell your ide's to use a specific version.

in that. Hope it helps!!
My trick is to create a transparent .png with the color and use background:url()
.
It's basically like a callback that express.js use after a certain part of the code is executed and done, you can use it to make sure that part of code is done and what you wanna do next thing, but always be mindful you only can do one res.send
in your each REST block...
So you can do something like this as a simple next()
example:
app.get("/", (req, res, next) => {
console.log("req:", req, "res:", res);
res.send(["data": "whatever"]);
next();
},(req, res) =>
console.log("it's all done!");
);
It's also very useful when you'd like to have a middleware in your app...
To load the middleware function, call app.use(), specifying the middleware function. For example, the following code loads the myLogger middleware function before the route to the root path (/).
var express = require('express');
var app = express();
var myLogger = function (req, res, next) {
console.log('LOGGED');
next();
}
app.use(myLogger);
app.get('/', function (req, res) {
res.send('Hello World!');
})
app.listen(3000);
Try this
SELECT distinct id
FROM (SELECT id, ROW_NUMBER() OVER (ORDER BY id) AS RowNum
FROM table
WHERE fid = 64) t
Or use RANK()
instead of row number and select records DISTINCT rank
SELECT id
FROM (SELECT id, ROW_NUMBER() OVER (PARTITION BY id ORDER BY id) AS RowNum
FROM table
WHERE fid = 64) t
WHERE t.RowNum=1
This also returns the distinct ids
$("#first").val(); // this will give you value of selected element. i.e. 1,2,3.

Yes, it's historical. Without it, it creates an old-style class.
If you use type()
on an old-style object, you just get "instance". On a new-style object you get its class.
Use getColorStateList
like this
setTextColor(resources.getColorStateList(R.color.button_states_color))
instead of getColor
setTextColor(resources.getColor(R.color.button_states_color))
The problem id because of inp.read();
method. Its return single character at a time and because you are storing it into int type of array so that is just storing ascii value of that.
What you can do simply

String s= inp.readLine();
String[] intValues = inp.readLine().split(" ");
int[] m= new int[2];
m[0]=Integer.parseInt(intValues[0]);
m[1]=Integer.parseInt(intValues[1]);
// Checking whether I am taking the inputs correctly
System.out.println(s);
System.out.println(m[0]);
System.out.println(m[1]);

@robertc has it right, but you also need to notice that svg, #container
causes the svg to be scaled exponentially for anything but 100% (once for #container
and once for svg
).
In other words, if I applied 50% h/w to both elements, it's actually 50% of 50%, or .5 * .5, which equals .25, or 25% scale.
One selector works fine when used as @robertc suggests.
svg {
width:50%;
height:50%;
}
You could use a string stream and read the elements into the vector.
Here are many different examples...
A copy of one of the examples:
std::vector<std::string> split(const std::string& s, char seperator)
{
std::vector<std::string> output;
std::string::size_type prev_pos = 0, pos = 0;
while((pos = s.find(seperator, pos)) != std::string::npos)
{
std::string substring( s.substr(prev_pos, pos-prev_pos) );
output.push_back(substring);

The character set is part of the locale, which is determined by the value of NLS_LANG
. As the documentation makes clear this is an operating system variable:
NLS_LANG
is set as an environment variable on UNIX platforms.NLS_LANG
is set in the registry on Windows platforms.
Now we can use ALTER SESSION
to change the values for a couple of locale elements, NLS_LANGUAGE and NLS_TERRITORY. But not, alas, the character set. The reason for this discrepancy is - I think - that the language and territory simply effect how Oracle interprets the stored data, e.g. whether to display a comma or a period when displaying a large number. Wheareas the character set is concerned with how the client application renders the displayed data. This information is picked up by the client application at startup time, and cannot be changed from within.

screws up elements inserted via jQuery plugins (autocomplete, popup,

on your container because the footer will stick at the bottom of window and won't adapt to long content.flex-grow:1
rather than flex:1

.Generally you can do
select * from your_table
order by case when name = 'core' then 1 else 2 end,
priority
Especially in MySQL you can also do
select * from your_table
order by name <> 'core',
priority
Since the result of a comparision in MySQL is either 0
or 1
and you can sort by that result.
Try:
to_dict = lambda **k: k
apple = 1
banana = 'f'
carrot = 3
to_dict(apple=apple, banana=banana, carrot=carrot)
#{'apple': 1, 'banana': 'f', 'carrot': 3}

php -i | grep libxml
If this is a personal script, rather than one you're planning on distributing, it might be simpler to write a shell function for this:
function warextract { jar xf $1 $2 && mv $2 $3 }
which you could then call from python like so:
warextract /home/foo/bar/Portal.ear Binaries.war /home/foo/bar/baz/
If you really feel like it, you could use sed to parse out the filename from the path, so that you'd be able to call it with
warextract /home/foo/bar/Portal.ear /home/foo/bar/baz/Binaries.war
I'll leave that as an excercise to the reader, though.
Of course, since this will extract the .war out into the current directory first, and then move it, it has the possibility of overwriting something with the same name where you are.
Changing directory, extracting it, and cd-ing back is a bit cleaner, but I find myself using little one-line shell functions like this all the time when I want to reduce code clutter.
I assume you're trying to tunnel into some unix box.
Make sure X11 forwarding is enabled in your PuTTY settings.
Several answers here have addressed that .length()
gives the wrong results with multibyte characters, but there are 11 answers and none of them have provided a solution.
First of all, it's important to know what you mean by "length". For a motivating example, consider the string "Z??????a???????_l?`?¨???????g????????o???¯????????" (note that some languages, notably Thai, actually use combining diacritical marks, so this isn't just useful for 15-year-old memes, but obviously that's the most important use case). Assume it is encoded in UTF-8. There are 3 ways we can talk about the length of this string:
00000000: 5acd a5cd accc becd 89cc b3cc ba61 cc92 Z............a..
00000010: cc92 cd8c cc8b cdaa ccb4 cd95 ccb2 6ccd ..............l.

There are C++ classes for ICU, but they require converting to UTF-16. You can use the C types and macros directly to get some UTF-8 support:
#include <memory>
#include <iostream>
#include <unicode/utypes.h>
#include <unicode/ubrk.h>
#include <unicode/utext.h>
//
// C++ helpers so we can use RAII
//
// Note that ICU internally provides some C++ wrappers (such as BreakIterator), however these only seem to work
// for UTF-16 strings, and require transforming UTF-8 to UTF-16 before use.
// If you already have UTF-16 strings or can take the performance hit, you should probably use those instead of
// the C functions. See: http://icu-project.org/apiref/icu4c/
//
struct UTextDeleter { void operator()(UText* ptr) { utext_close(ptr); } };
struct UBreakIteratorDeleter { void operator()(UBreakIterator* ptr) { ubrk_close(ptr); } };

Boost.Locale wraps ICU, and might provide a nicer interface. However, it still requires conversion to/from UTF-16.
You can also use inspect.getdoc
. It cleans up the __doc__
by normalizing tabs to spaces and left shifting the doc body to remove common leading spaces.
Look at Linked List as a data structure. It's mechanism to represent self-aggregation in OOD. And you may think of it as real world object (for some people it is reality)
The simplest way to log out and redirect back to the login or index:
<?php
if (!isset($_SESSION)) { session_start(); }
$_SESSION = array();
session_destroy();
header("Location: login.php"); // Or wherever you want to redirect
exit();
?>
It's an indication that connection pooling is being used (which is a good thing).
About answer 3 removing only the last \n off string code :
if (!s.empty() && s[s.length()-1] == '\n') {
s.erase(s.length()-1);
}
Will the if condition not fail if the string is really empty ?
Is it not better to do :
if (!s.empty())
{
if (s[s.length()-1] == '\n')
s.erase(s.length()-1);
}
To add to @migontech's answer and also his address his comment that you could "probably make it more generic", here's a way to do it. The below will allow you to search by any property:
.filter('getByProperty', function() {
return function(propertyName, propertyValue, collection) {
var i=0, len=collection.length;
for (; i<len; i++) {
if (collection[i][propertyName] == +propertyValue) {
return collection[i];
}
}
return null;
}
});
The call to filter would then become:
var found = $filter('getByProperty')('id', fish_id, $scope.fish);
Note, I removed the unary(+) operator to allow for string-based matches...
You can simply use JSON.parse
.
The definition of the JSON
object is part of the ECMAScript 5 specification. node.js is built on Google Chrome's V8 engine, which adheres to ECMA standard. Therefore, node.js also has a global object JSON
[docs].
Note - JSON.parse
can tie up the current thread because it is a synchronous method. So if you are planning to parse big JSON objects use a streaming json parser.
Upgrading Atom appears to break command line functionality on the occasion. Looks like in my case it created two versions of the application instead of overwriting them. Occurs because the new file structure doesn't match file paths created by "Atom -> Install Shell Commands". In order fix the issue you'll need to do the following.
After that everything should work just like it did before. Hopefully this saves someone 30 minutes of poking around.
You can simply open the phpmyadmin page from your browser, then open any existing database -> go to Privileges tab, click on your root user and then a popup window will appear, you can set your password there.. Hope this Helps.
I'm new in ASP.NET MVC. I faced the same problem, the following is my workable in my Erorr.vbhtml (it work if you only need to log the error using Elmah log)
@ModelType System.Web.Mvc.HandleErrorInfo
@Code
ViewData("Title") = "Error"
Dim item As HandleErrorInfo = CType(Model, HandleErrorInfo)
//To log error with Elmah
Elmah.ErrorLog.GetDefault(HttpContext.Current).Log(New Elmah.Error(Model.Exception, HttpContext.Current))
End Code

Well I ran your A and B examples 20 times each, looping 100 million times.(JVM - 1.5.0)
A: average execution time: .074 sec
B: average execution time : .067 sec
To my surprise B was slightly faster. As fast as computers are now its hard to say if you could accurately measure this. I would code it the A way as well but I would say it doesn't really matter.
Since the introduction of Visual Studio 2015, this location has changed and is added into your solution root under the following location:

A while ago i wrote a detailed article about Hibernate key generators: http://blog.eyallupu.com/2011/01/hibernatejpa-identity-generators.html
Choosing the correct generator is a complicated task but it is important to try and get it right as soon as possible - a late migration might be a nightmare.
A little off topic but a good chance to raise a point usually overlooked which is sharing keys between applications (via API). Personally I always prefer surrogate keys and if I need to communicate my objects with other systems I don't expose my key (even though it is a surrogate one) – I use an additional ‘external key’. As a consultant I have seen more than once 'great' system integrations using object keys (the 'it is there let's just use it' approach) just to find a year or two later that one side has issues with the key range or something of the kind requiring a deep migration on the system exposing its internal keys. Exposing your key means exposing a fundamental aspect of your code to external constrains shouldn’t really be exposed to.
Yes, contains is case sensitive. You can use java.util.regex.Pattern with the CASE_INSENSITIVE flag for case insensitive matching:
Pattern.compile(Pattern.quote(wantedStr), Pattern.CASE_INSENSITIVE).matcher(source).find();
EDIT: If s2 contains regex special characters (of which there are many) it's important to quote it first. I've corrected my answer since it is the first one people will see, but vote up Matt Quail's since he pointed this out.
You can create your own cursors and set them as the cursor using cursor: url('path-to-your-cursor');
, or find Firefox's and copy them (bonus: a nice consistent look in every browser).
from python 3.4 you may use :
import pathlib
def delete_folder(pth) :
for sub in pth.iterdir() :
if sub.is_dir() :
delete_folder(sub)
else :
sub.unlink()
pth.rmdir() # if you just want to delete the dir content but not the dir itself, remove this line
where pth
is a pathlib.Path
instance. Nice, but may not be the fastest.
This is probably the easiest way, not the prettiest though:
SELECT *,
(SELECT Count(*) FROM eventsTable WHERE columnName = 'Business') as RowCount
FROM eventsTable
WHERE columnName = 'Business'
This will also work without having to use a group by
SELECT *, COUNT(*) OVER () as RowCount
FROM eventsTables
WHERE columnName = 'Business'
it's android:button="@drawable/selector_checkbox"
to make it work
dat <- data.frame(x1 = c(1,2,3, NA, 5), x2 = c(100, NA, 300, 400, 500))
na.omit(dat)

Finally, I get the cell using the following code:
UITableViewCell *cell = (UITableViewCell *)[(UITableView *)self.view cellForRowAtIndexPath:nowIndex];
Because the class is extended UITableViewController:
@interface SearchHotelViewController : UITableViewController
So, the self
is "SearchHotelViewController".
In my legacy app Array.from of prototype js was conflicting with angular's Array.from that was causing this problem. I resolved it by saving angular's Array.from version and reassigning it after prototype load.
FWIW I created a JavaScript class that can be used at run-time.
It's over on GitHub, here.
There is a readme there with a more in-depth explanation, but I'll do a quick example below:
var ba = new BootstrapAlert();
ba.addP("Some content here");
$("body").append(ba.render());
The above would create a simple primary alert with a paragraph element inside containing the text "Some content here".
There are also options that can be set on initialisation.
For your requirement you'd do:
var ba = new BootstrapAlert({
dismissible: true,
background: 'warning'
});
ba.addP("Invalid Credentials");
$("body").append(ba.render());
The render
method will return an HTML element, which can then be inserted into the DOM. In this case, we append it to the bottom of the body tag.
This is a work in progress library, but it still is in a very good working order.
You can use the _count
API to get the value for the size
parameter:
http://localhost:9200/foo/_count?q=<your query>
Returns {count:X, ...}
. Extract value 'X' and then do the actual query:
http://localhost:9200/foo/_search?q=<your query>&size=X
If your grep -i does not work then try using tr command to convert the the output of your file to lower case and then pipe it into standard grep with whatever you are looking for. (it sounds complicated but the actual command which I have provided for you is not !).
Notice the tr command does not change the content of your original file, it just converts it just before it feeds it into grep.
1.here is how you can do this on a file
tr '[:upper:]' '[:lower:]' <your_file.txt|grep what_ever_you_are_searching_in_lower_case
2.or in your case if you are just echoing something
echo "ABC"|tr '[:upper:]' '[:lower:]' | grep abc
The only thing you need to think about in this case is, in which directory you are on your computer.
Your command line window shows C:\users\rei0d\desktop\
as your current directory.
So the only thing you really need to do is:
Remove the desktop
by "going up" with the command cd ..
.
So the complete command would be:
cd ..
ping XXX.XXX.XXX.XXX -t
You will need to melt
your dataframe to get it into the so-called long format:
require(reshape2)
sample.data.M <- melt(sample.data)
Now your field values are represented by their own rows and identified through the variable column. This can now be leveraged within the ggplot aesthetics:
require(ggplot2)
c <- ggplot(sample.data.M, aes(x = Rank, y = value, fill = variable))
c + geom_bar(stat = "identity")
Instead of stacking you may also be interested in showing multiple plots using facets:
c <- ggplot(sample.data.M, aes(x = Rank, y = value))
c + facet_wrap(~ variable) + geom_bar(stat = "identity")
Looking my projects:
The click event is not bound to your new element, use a jQuery.on
to handle the click.
The problem is your query returned false
meaning there was an error in your query. After your query you could do the following:
if (!$result) {
die(mysqli_error($link));
}
Or you could combine it with your query:
$results = mysqli_query($link, $query) or die(mysqli_error($link));
That will print out your error.
Also... you need to sanitize your input. You can't just take user input and put that into a query. Try this:
$query = "SELECT * FROM shopsy_db WHERE name LIKE '%" . mysqli_real_escape_string($link, $searchTerm) . "%'";
In reply to: Table 'sookehhh_shopsy_db.sookehhh_shopsy_db' doesn't exist
Are you sure the table name is sookehhh_shopsy_db? maybe it's really like users or something.
Starting with PowerShell 6, you get the filename without extension like so:

I tried to edit the answer provided by marc_s however it wasn't accepted for some reason. It formats the sql for easier reading, includes the schema and also names the Default name so that this can easily be pasted into other code.

I find the existing answers don't actually give the size of tables on the disk, which is more helpful. This query gives more accurate disk estimate compared to table size based on data_length & index. I had to use this for an AWS RDS instance where you cannot physically examine the disk and check file sizes.
select NAME as TABLENAME,FILE_SIZE/(1024*1024*1024) as ACTUAL_FILE_SIZE_GB
, round(((data_length + index_length) / 1024 / 1024/1024), 2) as REPORTED_TABLE_SIZE_GB
from INFORMATION_SCHEMA.INNODB_SYS_TABLESPACES s
join INFORMATION_SCHEMA.TABLES t
on NAME = Concat(table_schema,'/',table_name)
order by FILE_SIZE desc
You need to put the files into an array in order to sort and find the last modified file.
$files = array();
if ($handle = opendir('.')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
$files[filemtime($file)] = $file;
}
}
closedir($handle);
// sort
ksort($files);
// find the last modification
$reallyLastModified = end($files);
foreach($files as $file) {
$lastModified = date('F d Y, H:i:s',filemtime($file));
if(strlen($file)-strpos($file,".swf")== 4){
if ($file == $reallyLastModified) {
// do stuff for the real last modified file
}
echo "<tr><td><input type=\"checkbox\" name=\"box[]\"></td><td><a href=\"$file\" target=\"_blank\">$file</a></td><td>$lastModified</td></tr>";
}
}
}
Not tested, but that's how to do it.
You have to modify the php.ini files in your xampp folder. Three files in three different places need to be changed.
Follow the following steps to enable curl library with XAMPP in Windows:
Browse and open the following 3 files
C:\Program Files\xampp\apache\bin\php.ini
C:\Program Files\xampp\php\php.ini
C:\Program Files\xampp\php\php4\php.ini
Uncomment the following line in your php.ini file by removing the semicolon (;).
;extension=php_curl.dll
After that it will look something like something below-
extension=php_curl.dll
Restart your Apache server.
Check your phpinfo()
to see whether curl has properly enabled or not.
Enjoy using curl() library.
Why not simply try this:
var promise = $http.get(url, {
params: query
}).then(function(response) {
console.log('Content-Range: ' + response.headers('Content-Range'));
return response.data;
});
Especially if you want to return the promise
so it could be a part of a promises chain.
If you are getting this from your own package.json
, just add the repository
field to it. (use the link to your actual repository):
"repository" : {
"type" : "git",
"url" : "https://github.com/npm/npm.git"
}
by splitting with newlines.
for line in wallop_of_a_string_with_many_lines.split('\n'):
#do_something..
if you iterate over a string, you are iterating char by char in that string, not by line.
>>>string = 'abc'
>>>for line in string:
print line

Here is the solution. I have fixed it. Here is the code
child: _status(data[index]["status"]),
Widget _status(status) {
if (status == "3") {
return Text('Process');
} else if(status == "1") {
return Text('Order');
} else {
return Text("Waiting");
}
}
I have read all the answers here and none of them was complete answer for my situation (which is exactly the same in this question) so here is how I gathered some parts of the suggested answers and come up with the exact solution:
echo this code below before any HTML output or header! (even a whitespace will cause PHP to send HTML/TEXT HTTP Header and it won't work) The code below should be your first line!
<?php header('HTTP/1.0 403 Forbidden');
$contents = file_get_contents('/home/your_account/public_html/domain.com/403.html', TRUE);
exit($contents);
Now you have the exact solution. I checked and verified with CPANEL Latest Visitors and it is registered as exact 403 event.
exclude()
The Django issue tracker has the remarkable entry #5763, titled "Queryset doesn't have a "not equal" filter operator". It is remarkable because (as of April 2016) it was "opened 9 years ago" (in the Django stone age), "closed 4 years ago", and "last changed 5 months ago".
Read through the discussion, it is interesting.
Basically, some people argue __ne
should be added
while others say exclude()
is clearer and hence __ne
should not be added.
(I agree with the former, because the latter argument is
roughly equivalent to saying Python should not have !=
because
it has ==
and not
already...)

I found the above answers quite useful but not really general purpose, they all need some other major build system like Ant or Maven.
I wanted to generate a report in a simple one-shot command that I could call from anything (from a build, test or just myself) so I have created junit2html which can be found here: https://github.com/inorton/junit2html
You can install it by doing:
pip install junit2html
The reason eval
and exec
are so dangerous is that the default compile
function will generate bytecode for any valid python expression, and the default eval
or exec
will execute any valid python bytecode. All the answers to date have focused on restricting the bytecode that can be generated (by sanitizing input) or building your own domain-specific-language using the AST.
Instead, you can easily create a simple eval
function that is incapable of doing anything nefarious and can easily have runtime checks on memory or time used. Of course, if it is simple math, than there is a shortcut.
c = compile(stringExp, 'userinput', 'eval')
if c.co_code[0]==b'd' and c.co_code[3]==b'S':
return c.co_consts[ord(c.co_code[1])+ord(c.co_code[2])*256]
The way this works is simple, any constant mathematic expression is safely evaluated during compilation and stored as a constant. The code object returned by compile consists of d
, which is the bytecode for LOAD_CONST
, followed by the number of the constant to load (usually the last one in the list), followed by S
, which is the bytecode for RETURN_VALUE
. If this shortcut doesn't work, it means that the user input isn't a constant expression (contains a variable or function call or similar).
This also opens the door to some more sophisticated input formats. For example:
stringExp = "1 + cos(2)"
This requires actually evaluating the bytecode, which is still quite simple. Python bytecode is a stack oriented language, so everything is a simple matter of TOS=stack.pop(); op(TOS); stack.put(TOS)
or similar. The key is to only implement the opcodes that are safe (loading/storing values, math operations, returning values) and not unsafe ones (attribute lookup). If you want the user to be able to call functions (the whole reason not to use the shortcut above), simple make your implementation of CALL_FUNCTION
only allow functions in a 'safe' list.
from dis import opmap
from Queue import LifoQueue
from math import sin,cos

globs = {'sin':sin, 'cos':cos}

if name in context['locals']:
stack.put(context['locals'][name])
else:
stack.put(context['globals'][name])
def RETURN_VALUE(context):
return stack.get()
opfuncs = {
opmap['BINARY_ADD']: BINARY(operator.add),
opmap['UNARY_INVERT']: UNARY(operator.invert),
opmap['CALL_FUNCTION']: CALL_FUNCTION,
opmap['LOAD_CONST']: LOAD_CONST,

}
def VMeval(c):
context = dict(locals={}, globals=globs, code=c)
bci = iter(c.co_code)
for bytecode in bci:
func = opfuncs[ord(bytecode)]
if func.func_code.co_argcount==1:
ret = func(context)
else:
args = ord(bci.next()), ord(bci.next())
ret = func(context, args)
if ret:
return ret
def evaluate(expr):
return VMeval(compile(expr, 'userinput', 'eval'))
Obviously, the real version of this would be a bit longer (there are 119 opcodes, 24 of which are math related). Adding STORE_FAST
and a couple others would allow for input like 'x=5;return x+x
or similar, trivially easily. It can even be used to execute user-created functions, so long as the user created functions are themselves executed via VMeval (don't make them callable!!! or they could get used as a callback somewhere). Handling loops requires support for the goto
bytecodes, which means changing from a for
iterator to while
and maintaining a pointer to the current instruction, but isn't too hard. For resistance to DOS, the main loop should check how much time has passed since the start of the calculation, and certain operators should deny input over some reasonable limit (BINARY_POWER
being the most obvious).
While this approach is somewhat longer than a simple grammar parser for simple expressions (see above about just grabbing the compiled constant), it extends easily to more complicated input, and doesn't require dealing with grammar (compile
take anything arbitrarily complicated and reduces it to a sequence of simple instructions).
const arr= [1, 2, 3]
arr.forEach(function(element){
if(arr[arr.length-1] === element){
console.log("Last Element")
}
})
In jQuery, you design a page, and then you make it dynamic. This is because jQuery was designed for augmentation and has grown incredibly from that simple premise.
But in AngularJS, you must start from the ground up with your architecture in mind. Instead of starting by thinking "I have this piece of the DOM and I want to make it do X", you have to start with what you want to accomplish, then go about designing your application, and then finally go about designing your view.
Similarly, don't start with the idea that jQuery does X, Y, and Z, so I'll just add AngularJS on top of that for models and controllers. This is really tempting when you're just starting out, which is why I always recommend that new AngularJS developers don't use jQuery at all, at least until they get used to doing things the "Angular Way".
I've seen many developers here and on the mailing list create these elaborate solutions with jQuery plugins of 150 or 200 lines of code that they then glue into AngularJS with a collection of callbacks and $apply
s that are confusing and convoluted; but they eventually get it working! The problem is that in most cases that jQuery plugin could be rewritten in AngularJS in a fraction of the code, where suddenly everything becomes comprehensible and straightforward.
The bottom line is this: when solutioning, first "think in AngularJS"; if you can't think of a solution, ask the community; if after all of that there is no easy solution, then feel free to reach for the jQuery. But don't let jQuery become a crutch or you'll never master AngularJS.
First know that single-page applications are applications. They're not webpages. So we need to think like a server-side developer in addition to thinking like a client-side developer. We have to think about how to divide our application into individual, extensible, testable components.
So then how do you do that? How do you "think in AngularJS"? Here are some general principles, contrasted with jQuery.
In jQuery, we programmatically change the view. We could have a dropdown menu defined as a ul
like so:
<ul class="main-menu">
<li class="active">
<a href="#/home">Home</a>
</li>
<li>
<a href="#/menu1">Menu 1</a>
<ul>
<li><a href="#/sm1">Submenu 1</a></li>
<li><a href="#/sm2">Submenu 2</a></li>
<li><a href="#/sm3">Submenu 3</a></li>
</ul>
</li>
<li>
<a href="#/home">Menu 2</a>
</li>
</ul>
In jQuery, in our application logic, we would activate it with something like:
$('.main-menu').dropdownMenu();
When we just look at the view, it's not immediately obvious that there is any functionality here. For small applications, that's fine. But for non-trivial applications, things quickly get confusing and hard to maintain.
In AngularJS, though, the view is the official record of view-based functionality. Our ul
declaration would look like this instead:
<ul class="main-menu" dropdown-menu>
...
</ul>
These two do the same thing, but in the AngularJS version anyone looking at the template knows what's supposed to happen. Whenever a new member of the development team comes on board, she can look at this and then know that there is a directive called dropdownMenu
operating on it; she doesn't need to intuit the right answer or sift through any code. The view told us what was supposed to happen. Much cleaner.
Developers new to AngularJS often ask a question like: how do I find all links of a specific kind and add a directive onto them. The developer is always flabbergasted when we reply: you don't. But the reason you don't do that is that this is like half-jQuery, half-AngularJS, and no good. The problem here is that the developer is trying to "do jQuery" in the context of AngularJS. That's never going to work well. The view is the official record. Outside of a directive (more on this below), you never, ever, never change the DOM. And directives are applied in the view, so intent is clear.
Remember: don't design, and then mark up. You must architect, and then design.
This is by far one of the most awesome features of AngularJS and cuts out a lot of the need to do the kinds of DOM manipulations I mentioned in the previous section. AngularJS will automatically update your view so you don't have to! In jQuery, we respond to events and then update content. Something like:
$.ajax({
url: '/myEndpoint.json',
success: function ( data, status ) {
$('ul#log').append('<li>Data Received!</li>');
}
});
For a view that looks like this:
<ul class="messages" id="log">
</ul>
Apart from mixing concerns, we also have the same problems of signifying intent that I mentioned before. But more importantly, we had to manually reference and update a DOM node. And if we want to delete a log entry, we have to code against the DOM for that too. How do we test the logic apart from the DOM? And what if we want to change the presentation?
This a little messy and a trifle frail. But in AngularJS, we can do this:
$http( '/myEndpoint.json' ).then( function ( response ) {
$scope.log.push( { msg: 'Data Received!' } );
});
And our view can look like this:
<ul class="messages">
<li ng-repeat="entry in log">{{ entry.msg }}</li>
</ul>
But for that matter, our view could look like this:
<div class="messages">
<div class="alert" ng-repeat="entry in log">
{{ entry.msg }}
</div>
</div>
And now instead of using an unordered list, we're using Bootstrap alert boxes. And we never had to change the controller code! But more importantly, no matter where or how the log gets updated, the view will change too. Automatically. Neat!
Though I didn't show it here, the data binding is two-way. So those log messages could also be editable in the view just by doing this: <input ng-model="entry.msg" />
. And there was much rejoicing.
In jQuery, the DOM is kind of like the model. But in AngularJS, we have a separate model layer that we can manage in any way we want, completely independently from the view. This helps for the above data binding, maintains separation of concerns, and introduces far greater testability. Other answers mentioned this point, so I'll just leave it at that.
And all of the above tie into this over-arching theme: keep your concerns separate. Your view acts as the official record of what is supposed to happen (for the most part); your model represents your data; you have a service layer to perform reusable tasks; you do DOM manipulation and augment your view with directives; and you glue it all together with controllers. This was also mentioned in other answers, and the only thing I would add pertains to testability, which I discuss in another section below.
To help us out with separation of concerns is dependency injection (DI). If you come from a server-side language (from Java to PHP) you're probably familiar with this concept already, but if you're a client-side guy coming from jQuery, this concept can seem anything from silly to superfluous to hipster. But it's not. :-)
From a broad perspective, DI means that you can declare components very freely and then from any other component, just ask for an instance of it and it will be granted. You don't have to know about loading order, or file locations, or anything like that. The power may not immediately be visible, but I'll provide just one (common) example: testing.
Let's say in our application, we require a service that implements server-side storage through a REST API and, depending on application state, local storage as well. When running tests on our controllers, we don't want to have to communicate with the server - we're testing the controller, after all. We can just add a mock service of the same name as our original component, and the injector will ensure that our controller gets the fake one automatically - our controller doesn't and needn't know the difference.
Speaking of testing...
This is really part of section 3 on architecture, but it's so important that I'm putting it as its own top-level section.
Out of all of the many jQuery plugins you've seen, used, or written, how many of them had an accompanying test suite? Not very many because jQuery isn't very amenable to that. But AngularJS is.
In jQuery, the only way to test is often to create the component independently with a sample/demo page against which our tests can perform DOM manipulation. So then we have to develop a component separately and then integrate it into our application. How inconvenient! So much of the time, when developing with jQuery, we opt for iterative instead of test-driven development. And who could blame us?
But because we have separation of concerns, we can do test-driven development iteratively in AngularJS! For example, let's say we want a super-simple directive to indicate in our menu what our current route is. We can declare what we want in the view of our application:
<a href="/hello" when-active>Hello</a>
Okay, now we can write a test for the non-existent when-active
directive:
it( 'should add "active" when the route changes', inject(function() {
var elm = $compile( '<a href="/hello" when-active>Hello</a>' )( $scope );
$location.path('/not-matching');
expect( elm.hasClass('active') ).toBeFalsey();
$location.path( '/hello' );
expect( elm.hasClass('active') ).toBeTruthy();
}));
And when we run our test, we can confirm that it fails. Only now should we create our directive:
.directive( 'whenActive', function ( $location ) {
return {
scope: true,
link: function ( scope, element, attrs ) {
scope.$on( '$routeChangeSuccess', function () {
if ( $location.path() == element.attr( 'href' ) ) {
element.addClass( 'active' );
}
else {
element.removeClass( 'active' );
}
});
}
};
});
Our test now passes and our menu performs as requested. Our development is both iterative and test-driven. Wicked-cool.
You'll often hear "only do DOM manipulation in a directive". This is a necessity. Treat it with due deference!
But let's dive a little deeper...
Some directives just decorate what's already in the view (think ngClass
) and therefore sometimes do DOM manipulation straight away and then are basically done. But if a directive is like a "widget" and has a template, it should also respect separation of concerns. That is, the template too should remain largely independent from its implementation in the link and controller functions.
AngularJS comes with an entire set of tools to make this very easy; with ngClass
we can dynamically update the class; ngModel
allows two-way data binding; ngShow
and ngHide
programmatically show or hide an element; and many more - including the ones we write ourselves. In other words, we can do all kinds of awesomeness without DOM manipulation. The less DOM manipulation, the easier directives are to test, the easier they are to style, the easier they are to change in the future, and the more re-usable and distributable they are.
I see lots of developers new to AngularJS using directives as the place to throw a bunch of jQuery. In other words, they think "since I can't do DOM manipulation in the controller, I'll take that code put it in a directive". While that certainly is much better, it's often still wrong.
Think of the logger we programmed in section 3. Even if we put that in a directive, we still want to do it the "Angular Way". It still doesn't take any DOM manipulation! There are lots of times when DOM manipulation is necessary, but it's a lot rarer than you think! Before doing DOM manipulation anywhere in your application, ask yourself if you really need to. There might be a better way.
Here's a quick example that shows the pattern I see most frequently. We want a toggleable button. (Note: this example is a little contrived and a skosh verbose to represent more complicated cases that are solved in exactly the same way.)
.directive( 'myDirective', function () {
return {
template: '<a class="btn">Toggle me!</a>',
link: function ( scope, element, attrs ) {
var on = false;
$(element).click( function () {
on = !on;
$(element).toggleClass('active', on);
});
}
};
});
There are a few things wrong with this:
angular.element
and our component will still work when dropped into a project that doesn't have jQuery.angular.element
) will always use jQuery if it was loaded! So we needn't use the $
- we can just use angular.element
.$
- the element
that is passed to the link
function would already be a jQuery element! This directive can be rewritten (even for very complicated cases!) much more simply like so:
.directive( 'myDirective', function () {
return {
scope: true,
template: '<a class="btn" ng-class="{active: on}" ng-click="toggle()">Toggle me!</a>',
link: function ( scope, element, attrs ) {
scope.on = false;
scope.toggle = function () {
scope.on = !scope.on;
};
}
};
});
Again, the template stuff is in the template, so you (or your users) can easily swap it out for one that meets any style necessary, and the logic never had to be touched. Reusability - boom!
And there are still all those other benefits, like testing - it's easy! No matter what's in the template, the directive's internal API is never touched, so refactoring is easy. You can change the template as much as you want without touching the directive. And no matter what you change, your tests still pass.
w00t!
So if directives aren't just collections of jQuery-like functions, what are they? Directives are actually extensions of HTML. If HTML doesn't do something you need it to do, you write a directive to do it for you, and then use it just as if it was part of HTML.
Put another way, if AngularJS doesn't do something out of the box, think how the team would accomplish it to fit right in with ngClick
, ngClass
, et al.
Don't even use jQuery. Don't even include it. It will hold you back. And when you come to a problem that you think you know how to solve in jQuery already, before you reach for the $
, try to think about how to do it within the confines the AngularJS. If you don't know, ask! 19 times out of 20, the best way to do it doesn't need jQuery and to try to solve it with jQuery results in more work for you.
The best way to do this is as below:
public class Test {
public static void main(String args[]){
System.out.println(String.format("%s something", new Double(3.456)));
System.out.println(String.format("%s something", new Double(3.456234523452)));
System.out.println(String.format("%s something", new Double(3.45)));
System.out.println(String.format("%s something", new Double(3)));
}
}
Output:
3.456 something
3.456234523452 something
3.45 something
3.0 something
The only issue is the last one where .0 doesn't get removed. But if you are able to live with that then this works best. %.2f will round it to the last two decimal digits. So will DecimalFormat. If you need all the decimal places, but not the trailing zeros then this works best.

This helped me find the "Dynamic web project" in Eclipse 2020-12 version. Restart the eclipse and go to file->new->other->web and you will see project will be available.
You need to use -I
with each directory. But you can still delimit the directories with whitespace if you use (GNU) make's foreach

INC=$(DIR1) $(DIR2) ...
INC_PARAMS=$(foreach d, $(INC), -I$d)
Download Androidx86 from this This is an iso file, so you'd
need something like VMWare or VirtualBox to run it When creating the virtual machine, you need to set the type of guest OS as Linux
instead of Other.
After creating the virtual machine set the network adapter to 'Bridged'. · Start the VM and select 'Live CD VESA' at boot.
Now you need to find out the IP of this VM. Go to terminal in VM (use Alt+F1 & Alt+F7 to toggle) and use the netcfg command to find this.
Now you need open a command prompt and go to your android install folder (on host). This is usually C:\Program Files\Android\android-sdk\platform-tools>.
Type adb connect IP_ADDRESS. There done! Now you need to add Bluetooth. Plug in your USB Bluetooth dongle/Bluetooth device.
In VirtualBox screen, go to Devices>USB devices. Select your dongle.
Done! now your Android VM has Bluetooth. Try powering on Bluetooth and discovering/paring with other devices.
Now all that remains is to go to Eclipse and run your program. The Android AVD manager should show the VM as a device on the list.
Alternatively, Under settings of the virtual machine, Goto serialports -> Port 1 check Enable serial port select a port number then select port mode as disconnected click ok. now, start virtual machine. Under Devices -> USB Devices -> you can find your laptop bluetooth listed. You can simply check the option and start testing the android bluetooth application .
Here's are some examples:

Since assertThat
which was the old answer is now deprecated, I am posting the correct solution:
assertTrue(objectUnderTest instanceof TargetObject);
Although, there are many useful answers. Whereas, just to add another way to it. You can also use
git shortlog --author="<author name>" --format="%h %s"
It will show the output in the grouped manner:
<Author Name> (5):
4da3975f dependencies upgraded
49172445 runtime dependencies resolved
bff3e127 user-service, kratos, and guava dependencies upgraded
414b6f1e dropwizard :- service, rmq and db-sharding depedencies upgraded
a96af8d3 older dependecies removed
Here, total of 5 commits are done by <Author Name>
under the current branch. Whereas, you can also use --all
to enforce the search everywhere (all the branches) in the git repository.
One catch: git internally tries to match an input <author name>
with the name and email of the author in the git database. It is case-sensitive.

You can try:
int sum = startingNumber;
for (int i=0; i < positiveInteger; i++) {
sum += i;
}
cout << sum;
But much easier is to note that the sum 1+2+...+n = n*(n+1) / 2
, so you do not need a loop at all, just use the formula n*(n+1)/2
.
Just add this namespace,
using System.Linq;
This is the solution if your file has more . (dots) in the name.
<script type="text/javascript">var x = "file1.asdf.txt";
var y = x.split(".");
alert(y[(y.length)-1]);</script>
