first of all;

a Fragment must be inside a FragmentActivity, that's the first rule,

a FragmentActivity is quite similar to a standart Activity that you already know, besides having some Fragment oriented methods

second thing about Fragments, is that there is one important method you MUST call, wich is onCreateView, where you inflate your layout, think of it as the setContentLayout

here is an example:

    @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {     mView       = inflater.inflate(R.layout.fragment_layout, container, false);       return mView; } 

and continu your work based on that mView, so to find a View by id, call mView.findViewById(..);

for the FragmentActivity part:

the xml part "must" have a FrameLayout in order to inflate a fragment in it

        <FrameLayout             android:id="@+id/content_frame"             android:layout_width="match_parent"             android:layout_height="match_parent"  >         </FrameLayout> 

as for the inflation part

getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, new YOUR_FRAGMENT, "TAG").commit();

begin with these, as there is tons of other stuf you must know about fragments and fragment activities, start of by reading something about it (like life cycle) at the android developer site

After trying almost everything on this thread and others, continuing to Google, the only thing that worked for me, in the end, was to start Visual Studio as my AD user via command line:

cd C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE
runas /netonly /user:<comp\name.surname> devenv.exe

Original issue: [1]: https://developercommunity.visualstudio.com/content/problem/304224/git-failed-with-a-fatal-errorauthentication-failed.html

My situation is I'm on a personal machine connecting to a company's internal/local devops server (not cloud-based) that uses AD authorization. I had no issue with TFS, but with git could not get the clone to work (Git failed with a fatal error. Authentication failed for [url]) until I did that.

First you need to use this command

npm config set registry https://registry.your-registry.npme.io/

This we are doing to set our companies Enterprise registry as our default registry.

You can try other given solutions also.

exampleData=

        const json1 = [
            {id: 1, test: 1},
            {id: 2, test: 2},
            {id: 3, test: 3},
            {id: 4, test: 4},
            {id: 5, test: 5}
        ];

        const json2 = [
            {id: 3, test: 6},
            {id: 4, test: 7},
            {id: 5, test: 8},
            {id: 6, test: 9},
            {id: 7, test: 10}
        ];

example1=

        const finalData1 = json1.concat(json2).reduce(function (index, obj) {
            index[obj.id] = Object.assign({}, obj, index[obj.id]);
            return index;
        }, []).filter(function (res, obj) {
            return obj;
        });

example2=

        let hashData = new Map();

        json1.concat(json2).forEach(function (obj) {
            hashData.set(obj.id, Object.assign(hashData.get(obj.id) || {}, obj))
        });

        const finalData2 = Array.from(hashData.values());

I recommend second example , it is faster.

I have just tested the following pipeline and it works

parallel firstBranch: {
    stage ('Starting Test') 
    {
        build job: 'test1', parameters: [string(name: 'Environment', value: "$env.Environment")]
    }
}, secondBranch: {
    stage ('Starting Test2') 
    {
        build job: 'test2', parameters: [string(name: 'Environment', value: "$env.Environment")]
    }
}

This Job named 'trigger-test' accepts one parameter named 'Environment'

Job 'test1' and 'test2' are simple jobs:

Example for 'test1'

• One parameter named 'Environment'
• Pipeline : echo "$env.Environment-TEST1"

On execution, I am able to see both stages running in the same time

My problem was that my company proxy was getting in the way. The solution here was to identify the Root CA / certificate chain of our proxy, (on mac) export it from the keychain in .pem format, then export a variable for node to use.

export NODE_EXTRA_CA_CERTS=/path/to/your/CA/cert.pem

As other folks have mentioned, Java, ActiveX, Silverlight, Browser Helper Objects (BHOs) and other plugins are not supported in Microsoft Edge. Most modern browsers are moving away from plugins and toward standard HTML5 controls and technologies.

If you must continue to use the Java plugin in a corporate web app, consider adding the site to an Enterprise Mode site list. This will automatically prompt the user to open in IE.

This could also happen if you don't add $('#myTable').DataTable(); inside the document.ready

So instead of this

$('#myTable').DataTable();

Try This

$(document).ready(function() {
    $('#myTable').DataTable();
});

Once the user has marked "Do not ask again," the question can not be displayed again. But it can be explained to the user that he has previously denied the permission and must grant permission in the settings. And reference him to the settings, with the following code:

@Override
public void onRequestPermissionsResult(int permsRequestCode, String[] permissions, int[] grantResults) {

    if (grantResults.length > 0
            && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
        // now, you have permission go ahead
        // TODO: something

    } else {

        if (ActivityCompat.shouldShowRequestPermissionRationale(MainActivity.this,
                Manifest.permission.READ_CALL_LOG)) {
            // now, user has denied permission (but not permanently!)

        } else {

            // now, user has denied permission permanently!

            Snackbar snackbar = Snackbar.make(findViewById(android.R.id.content), "You have previously declined this permission.\n" +
                "You must approve this permission in \"Permissions\" in the app settings on your device.", Snackbar.LENGTH_LONG).setAction("Settings", new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                startActivity(new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS, Uri.parse("package:" + BuildConfig.APPLICATION_ID)));

            }
        });
        View snackbarView = snackbar.getView();
        TextView textView = (TextView) snackbarView.findViewById(android.support.design.R.id.snackbar_text);
        textView.setMaxLines(5);  //Or as much as you need
        snackbar.show();

        }

    }
    return;
}

The other plus of using RecycleView is animation, it can be done in two lines of code

RecyclerView.ItemAnimator itemAnimator = new DefaultItemAnimator();
        recyclerView.setItemAnimator(itemAnimator);

But the widget is still raw, e.g you can't create header and footer.

You could also use missing() to test whether or not the argument y was supplied:

fooBar <- function(x,y){
    if(missing(y)) {
        x
    } else {
        x + y
    }
}

fooBar(3,1.5)
# [1] 4.5
fooBar(3)
# [1] 3

In my case,I was getting error while refreshing gradle ('View'->Tool Windows->Gradle) tab and hit "refresh" and getting this error no such property gradleversion for class jetgradleplugin.

Either:

1. with row.name inside the apply(..., axis=1) call:

df = pandas.DataFrame([[1,2,3],[4,5,6]], columns=['a','b','c'], index=['x','y'])

   a  b  c
x  1  2  3
y  4  5  6

df.apply(lambda row: row.name, axis=1)

x    x
y    y

2. with iterrows() (slower)

DataFrame.iterrows() allows you to iterate over rows, and access their index:

for idx, row in df.iterrows():
    ...

The issue, I got is Earlier, I was using jdk 1.8.0_31 with certificate installed. I switched to jdk 1.8.0_191 but did not install certificate.

But, my projects were working fine, I realized that their dependencies were downloaded already. So, they would only compile and package those projects. But, this did not work for new maven projects as their dependencies were not downloaded earlier.

Solution::

1. Switch to earlier jdk version(which had certificate already installed) for your new project and do clean install
2. Download certificate again for the new jdk version that you have recently switched to and then do clean install

I GOT THIS problem too, and I solved it finally, this is the solution:

go to windows-->preference-->maven-->user settings

Change the settings.xml path to a valid path.

The path maybe not under .m2 directory (in your home directory)..

From a little search on google the first thing I tried was this

npm config set registry http://registry.npmjs.org/
npm config set proxy "your proxy"
npm config set https-proxy "your proxy"

But still npm seemed to lose connection when trying to do "npm install"s. then I ran this line in command prompt and now I can use npm install

set NODE_TLS_REJECT_UNAUTHORIZED=0

You can use this class : class="sticky-top alert alert-dismissible"

*Note : This will show popup once per browser as the data is stored in browser memory.

Try HTML localStorage.

Methods :

• localStorage.getItem('key');
• localStorage.setItem('key','value');

$j(document).ready(function() {
    if(localStorage.getItem('popState') != 'shown'){
        $j('#popup').delay(2000).fadeIn();
        localStorage.setItem('popState','shown')
    }

    $j('#popup-close, #popup').click(function() // You are clicking the close button
    {
        $j('#popup').fadeOut(); // Now the pop up is hidden.
    });
});

Working Demo

I had this issue as well. In my case, I was trying to get a post-receive Git hook to update a working copy on a server with each push. Tried to follow the instructions in the blog you linked to. Didn't work for me as well and overriding the settings on a per-user basis didn't seem to work either.

What I ended up having to do was disable SSL verification (as the article mentions) for Git as a whole. Not the perfect solution, but it'll work until I can figure out a better one.

I edited the Git config text file (with my favorite line-ending neutral app like Notepad++) located at:

C:\Program Files (x86)\Git\etc\gitconfig

In the [http] block, I added an option to disable sslVerify. It looked like this when I was done:

[http]
    sslVerify = false
    sslCAinfo = /bin/curl-ca-bundle.crt

That did the trick.

NOTE:

• This disables SSL verification and is not recommended as a long term solution.

• You can disable this per-repository which still isn't great, but localizes the setting.

• With the advent of LetsEncrypt.org, it is now fairly simple, automated and free to set up SSL as an alternative to self-signed certs and negates the need to turn off sslVerify.

Your mail won't be sent online unless you complete the two-step verification for your g-mail account and use that password.

You will get the proxy host and port from your server administrator or support.

After that set up

npm config set http_proxy http://username:[email protected]:itsport npm config set proxy http://username:[email protected]:itsport If there any special character in password try with % urlencode. Eg:- pound(hash) shuold be replaced by %23.

This worked for me...

UPDATE:

compile 'com.android.volley:volley:1.0.0'

OLD ANSWER: You need the next in your build.gradle of your app module:

dependencies {
        compile 'com.mcxiaoke.volley:library:1.0.19'
        (Rest of your dependencies)

    }

This is not the official repo but is a highly trusted one.

This Worked for me. For getting the latest code from master to my branch

git rebase origin/master

I used ProcessBuilder but had the same issue. The issue was with using command as one String line (like I would type it in cmd) instead of String array. In example from above. If I ran

ProcessBuilder pb = new ProcessBuilder("C:/Program Files/WinRAR/winrar x myjar.jar *.* new");
pb.directory(new File("H:/"));
pb. redirectErrorStream(true);

Process p = pb.start();

I got an error. But if I ran

ProcessBuilder pb = new ProcessBuilder("C:/Program Files/WinRAR/winrar", "x", "myjar.jar", "*.*", "new");
pb.directory(new File("H:/"));
pb. redirectErrorStream(true);

Process p = pb.start();

everything was OK.

urllib2 does not verify server certificate by default. Check this documentation.

Edit: As pointed out in below comment, this is not true anymore for newer versions (seems like >= 2.7.9) of Python. Refer the below ANSWER

You can do it with an confirm() message using Javascript.

For me this works perfect

insert into oehr.employees select * from employees where employee_id=99

I am not sure why you get error. The nature of the error code you have produced is the columns didn't match.

One good approach will be to use the answer @Parodo specified

You can try my package node-global-proxy which work with all node versions and most of http-client (axios, got, superagent, request etc.)

after install by

npm install node-global-proxy --save

a global proxy can start by

const proxy = require("node-global-proxy").default;

proxy.setConfig({
  http: "http://localhost:1080",
  https: "https://localhost:1080",
});
proxy.start();

/** Proxy working now! */

I've seen these 3 errors for pod command in terminal

pod install

[!] The MY_APP [Debug/Release] target overrides the HEADER_SEARCH_PATHS ...
[!] The MY_APP [Debug/Release] target overrides the OTHER_LDFLAGS ...
[!] The MY_APP [Debug/Release] target overrides the GCC_PREPROCESSOR_DEFINITIONS ...

All these 3 errors would be gone by adding $(inherited) to

1. Header Search Paths
2. Other Linker Flags
3. Preprocessor Macros

in Project -> Target -> Build Settings

And now the command would run without giving any errors

pod install

Here is a method using a lookup table of thresholds and associated colours to map the colours to the variable of interest.

 # make a grid 'Grd' of points and number points for side of square 'GrdD'
Grd <- expand.grid(seq(0.5,400.5,10),seq(0.5,400.5,10))
GrdD <- length(unique(Grd$Var1))

# Add z-values to the grid points
Grd$z <- rnorm(length(Grd$Var1), mean = 10, sd =2)

# Make a vector of thresholds 'Brks' to colour code z 
Brks <- c(seq(0,18,3),Inf)

# Make a vector of labels 'Lbls' for the colour threhsolds
Lbls <- Lbls <- c('0-3','3-6','6-9','9-12','12-15','15-18','>18')

# Make a vector of colours 'Clrs' for to match each range
Clrs <- c("grey50","dodgerblue","forestgreen","orange","red","purple","magenta")

# Make up lookup dataframe 'LkUp' of the lables and colours 
LkUp <- data.frame(cbind(Lbls,Clrs),stringsAsFactors = FALSE)

# Add a new variable 'Lbls' the grid dataframe mapping the labels based on z-value
Grd$Lbls <- as.character(cut(Grd$z, breaks = Brks, labels = Lbls))

# Add a new variable 'Clrs' to the grid dataframe based on the Lbls field in the grid and lookup table
Grd <- merge(Grd,LkUp, by.x = 'Lbls')

# Plot the grid using the 'Clrs' field for the colour of each point
plot(Grd$Var1,
     Grd$Var2,
     xlim = c(0,400),
     ylim = c(0,400),
     cex = 1.0,
     col = Grd$Clrs,
     pch = 20,
     xlab = 'mX',
     ylab = 'mY',
     main = 'My Grid',
     axes = FALSE,
     labels = FALSE,
     las = 1
)

axis(1,seq(0,400,100))
axis(2,seq(0,400,100),las = 1)
box(col = 'black')

legend("topleft", legend = Lbls, fill = Clrs, title = 'Z')

My solution shuffles the rows, then takes the first 75% of the rows as train and the last 25% as test. Super simples!

row_count <- nrow(orders_pivotted)
shuffled_rows <- sample(row_count)
train <- orders_pivotted[head(shuffled_rows,floor(row_count*0.75)),]
test <- orders_pivotted[tail(shuffled_rows,floor(row_count*0.25)),]

You need not to use even the package "tcltk". You can simply do as shown below:

write.csv(x, file = "c:\\myname\\yourfile.csv", row.names = FALSE)

Give your path inspite of "c:\myname\yourfile.csv".

Timer

As mentioned on the javadocs you are better off using a ScheduledThreadPoolExecutor.

ScheduledThreadPoolExecutor

Use this class when your use case requires multiple worker threads and the sleep interval is small. How small ? Well, I'd say about 15 minutes. The AlarmManager starts schedule intervals at this time and it seems to suggest that for smaller sleep intervals this class can be used. I do not have data to back the last statement. It is a hunch.

Service

Your service can be closed any time by the VM. Do not use services for recurring tasks. A recurring task can start a service, which is another matter entirely.

BroadcastReciever with AlarmManager

For longer sleep intervals (>15 minutes), this is the way to go. AlarmManager already has constants ( AlarmManager.INTERVAL_DAY ) suggesting that it can trigger tasks several days after it has initially been scheduled. It can also wake up the CPU to run your code.

You should use one of those solutions based on your timing and worker thread needs.

Why not:

<button type="submit">

Run this query from PostgreSQL:

SELECT version();

I was getting an "authenticationrequired" (407) error when clicking the [Sync] button (using the MS Git Provider), and this worked for me (VS 2013):

..\Program Files\Microsoft Visual Studio 12.0\Common7\IDE\devenv.exe.config

  <system.net>
    <defaultProxy useDefaultCredentials="true" enabled="true">
      <proxy proxyaddress="http://username:password@proxyip:port" />
    </defaultProxy>
    <settings>
      <ipv6 enabled="false"/>
      <servicePointManager expect100Continue="false"/>
    </settings>
  </system.net>

I think the magic for me was setting 'ipv6' to 'false' - not sure why (perhaps only IPv4 is supported in my case). I tried other ways as shown above, but I move the "settings" section AFTER "defaultProxy", and changed "ipv6", and it worked perfectly with my login added (every other way I tried in all other answers posted just failed for me).

Edit: Just found another work around (without changing the config file). For some reason, if I disable the windows proxy (it's a URL to a PAC file in my case), try again (it will fail), and re-enable the proxy, it works. Seems to cache something internally that gets reset when I do this (at least in my case).

import java.util.Scanner;

class CalculateGCD 
{   
  public static int calGCD(int a, int b) 
  { 
   int c=0,d=0;  
   if(a>b){c=b;} 
   else{c=a;}  
   for(int i=c; i>0; i--) 
   { 
    if(((a%i)+(b%i))==0) 
    { 
     d=i; 
     break; 
    } 
   } 
   return d;  
  }  

  public static void main(String args[]) 
  { 
   Scanner sc=new Scanner(System.in); 
   System.out.println("Enter the nos whose GCD is to be calculated:"); 
   int a=sc.nextInt(); 
   int b=sc.nextInt(); 
   System.out.println(calGCD(a,b));  
  } 
 } 

Log4js is one of the most popular logging library for nodejs application.

It supports many cool features:

1. Coloured console logging
2. Replacement of node's console.log functions (optional)
3. File appender, with log rolling based on file size
4. SMTP, GELF, hook.io, Loggly appender
5. Multiprocess appender (useful when you've got worker processes)
6. A logger for connect/express servers
7. Configurable log message layout/patterns
8. Different log levels for different log categories (make some parts of your app log as DEBUG, others only ERRORS, etc.)

Example:

1. Installation: npm install log4js

2. Configuration (./config/log4js.json):

   {"appenders": [
       {
           "type": "console",
           "layout": {
               "type": "pattern",
               "pattern": "%m"
           },
           "category": "app"
       },{
           "category": "test-file-appender",
           "type": "file",
           "filename": "log_file.log",
           "maxLogSize": 10240,
           "backups": 3,
           "layout": {
               "type": "pattern",
               "pattern": "%d{dd/MM hh:mm} %-5p %m"
           }
       }
   ],
   "replaceConsole": true }
   

3. Usage:

   var log4js = require( "log4js" );
   log4js.configure( "./config/log4js.json" );
   var logger = log4js.getLogger( "test-file-appender" );
   // log4js.getLogger("app") will return logger that prints log to the console
   logger.debug("Hello log4js");// store log in file
   

Regex is a very bad choice for this kind of task. Try to find a web service or an address database or a product which can clean address data instead.

• Address validation using Google Maps API

The accepted answer by Francisco Spaeth works and is easy to follow. However, I think that method of building JSON sucks! This was really driven home for me as I converted some Python to Java where I could use dictionaries and nested lists, etc. to build JSON with ridiculously greater ease.

What I really don't like is having to instantiate separate objects (and generally even name them) to build up these nestings. If you have a lot of objects or data to deal with, or your use is more abstract, that is a real pain!

I tried getting around some of that by attempting to clear and reuse temp json objects and lists, but that didn't work for me because all the puts and gets, etc. in these Java objects work by reference not value. So, I'd end up with JSON objects containing a bunch of screwy data after still having some ugly (albeit differently styled) code.

So, here's what I came up with to clean this up. It could use further development, but this should help serve as a base for those of you looking for more reasonable JSON building code:

import java.util.AbstractMap.SimpleEntry;
import java.util.ArrayList;
import java.util.List;
import org.json.simple.JSONObject;

//  create and initialize an object 
public static JSONObject buildObject( final SimpleEntry... entries ) { 
    JSONObject object = new JSONObject();
    for( SimpleEntry e : entries ) object.put( e.getKey(), e.getValue() );
    return object;
}

//  nest a list of objects inside another                          
public static void putObjects( final JSONObject parentObject, final String key,
                               final JSONObject... objects ) { 
    List objectList = new ArrayList<JSONObject>();
    for( JSONObject o : objects ) objectList.add( o );
    parentObject.put( key, objectList );
}   

Implementation example:

JSONObject jsonRequest = new JSONObject();
putObjects( jsonRequest, "parent1Key",
    buildObject( 
        new SimpleEntry( "child1Key1", "someValue" )
      , new SimpleEntry( "child1Key2", "someValue" ) 
    )
  , buildObject( 
        new SimpleEntry( "child2Key1", "someValue" )
      , new SimpleEntry( "child2Key2", "someValue" ) 
    )
);      

you are confusing the concept of appending and prepending. the following code is prepending:

sys.path.insert(1,'/thePathToYourFolder/')

it places the new information at the beginning (well, second, to be precise) of the search sequence that your interpreter will go through. sys.path.append() puts things at the very end of the search sequence.

it is advisable that you use something like virtualenv instead of manually coding your package directories into the PYTHONPATH everytime. for setting up various ecosystems that separate your site-packages and possible versions of python, read these two blogs:

1. python ecosystems introduction

2. bootstrapping python virtual environments

if you do decide to move down the path to environment isolation you would certainly benefit by looking into virtualenvwrapper: http://www.doughellmann.com/docs/virtualenvwrapper/

would take time to route through TeamViewer's servers (TeamViewer bypasses corporate Symmetric NATs by simply proxying traffic through their servers)

You'll find that TeamViewer rarely needs to relay traffic through their own servers. TeamViewer penetrates NAT and networks complicated by NAT using NAT traversal (I think it is UDP hole-punching, like Google's libjingle).

They do use their own servers to middle-man in order to do the handshake and connection set-up, but most of the time the relationship between client and server will be P2P (best case, when the hand-shake is successful). If NAT traversal fails, then TeamViewer will indeed relay traffic through its own servers.

I've only ever seen it do this when a client has been behind double-NAT, though.

The way a cherry-pick works is by taking the diff a changeset represents (the difference between the working tree at that point and the working tree of its parent), and applying it to your current branch.

So, if a commit has two or more parents, it also represents two or more diffs - which one should be applied?

You're trying to cherry pick fd9f578, which was a merge with two parents. So you need to tell the cherry-pick command which one against which the diff should be calculated, by using the -m option. For example, git cherry-pick -m 1 fd9f578 to use parent 1 as the base.

I can't say for sure for your particular situation, but using git merge instead of git cherry-pick is generally advisable. When you cherry-pick a merge commit, it collapses all the changes made in the parent you didn't specify to -m into that one commit. You lose all their history, and glom together all their diffs. Your call.

The better pattern is to create a standalone BroadcastReceiver. This insures that your app can respond to the broadcast, whether or not the Service is running. In fact, using this pattern may remove the need for a constant-running Service altogether.

Register the BroadcastReceiver in your Manifest, and create a separate class/file for it.

Eg:

<receiver android:name=".FooReceiver" >
    <intent-filter >
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

When the receiver runs, you simply pass an Intent (Bundle) to the Service, and respond to it in onStartCommand().

Eg:

public class FooReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        // do your work quickly!
        // then call context.startService();
    }   
}

After I stopped banging my head on the desk thinking of the entire week I spent running down this problem, I am sharing what worked for me. I have Win7 64 bit, 32-bit Oracle Client, and have my MVC 5 project set to run on x86 platform because of the Oracle bitness. I kept getting the same errors:

Could not load file or assembly 'Oracle.DataAccess' or one of its dependencies. An attempt was made to load a program with an incorrect format.

I reloaded the NuGet packages, I used copies of the DLLs that worked for others in different apps, I set the codebase in the dependent assembly to point to my project's bin folder, I tried CopyLocal as true or false, I tried everything. Finally I had enough else done I wanted to check in my code, and as a new contractor I didn't have subversion set up. While looking for a way to hook it into VS, I tripped over the answer. What I found worked was unchecking the "Use the 64 bit version of IIS Express for Web Sites and Projects" option under the Projects and Solutions => Web Projects section under the Tools=>Options menu.

Following these 2 guides a-way-to-let-users-define-custom-made-bound-if-statements and custom bound helpers I was able to adjust my shared views in this post on stackoverflow to use this instead of the standard #if statement. This should be more secure than just tossing an #if in there.

The custom bound helpers in that gist are outstanding.

In our case, the problem was fixed when we checked

git --exec-path

was pointing to a path that stopped to exist. (It was pointing to the path where we've compiled git and not where we copied afterwards for anyone to access it)

We did a:

export GIT_EXEC_PATH=<path_of_/libexec/git-core/>

and solved.

Try Jedi! There's a Vim plugin at https://github.com/davidhalter/jedi-vim.

It works just much better than anything else for Python in Vim. It even has support for renaming, goto, etc. The best part is probably that it really tries to understand your code (decorators, generators, etc. Just look at the feature list).

There are 2 main problems with static variables:

• Thread Safety - static resources are by definition not thread-safe
• Code Implicity - You do not know when a static variables is instantiated and whether or not it will be instantiated before another static variable

I think the easiest is to use Fastlane:

sudo gem install fastlane -NV
hash -r # for bash
rehash # for zsh
fastlane sigh resign ./path/app.ipa --signing_identity "Apple Distribution: Company Name" -p "my.mobileprovision"

File protocol URIs are like this

file://[HOST]/[PATH]

that's why you often see file URLs like this (3 slashes) file:///c:\path...

So if the host is server01, you want

file://server01/folder/path....

This is according to the wikipedia page on file:// protocols and checks out with .NET's Uri.IsWellFormedUriString method.

To automatically sync your forked repository with the parent repository, you could use the Pull App on GitHub.

Refer to the Readme for more details.

For advanced setup where you want to preserve your changes done to the forked repository, refer to my answer on a similar question here.

Sometimes you need to grep the process by name - in that case:

ps aux | grep simple-scan

Example output:

simple-scan  1090  0.0  0.1   4248  1432 ?        S    Jun11   0:00

You can do something like this:

[10, 20, 30, 40].slice(-1)[0]

console.log([10, 20, 30, 40].slice(-1)[0])

The amount of helper methods that can be added to a language is infinite. I suppose they just haven't considered adding this one.

I am running into a similar problem. PUT on a sub-resource seems to work when you want to update only a single field. However, sometimes you want to update a bunch of things: Think of a web form representing the resource with option to change some entries. The user's submission of form should not result in a multiple PUTs.

Here are two solution that I can think of:

1. do a PUT with the entire resource. On the server-side, define the semantics that a PUT with the entire resource ignores all the values that haven't changed.

2. do a PUT with a partial resource. On the server-side, define the semantics of this to be a merge.

2 is just a bandwidth-optimization of 1. Sometimes 1 is the only option if the resource defines some fields are required fields (think proto buffers).

The problem with both these approaches is how to clear a field. You will have to define a special null value (especially for proto buffers since null values are not defined for proto buffers) that will cause clearing of the field.

Comments?

A simplified version of SLaks' answer also works:

if ('abcdefghij'.indexOf(str) >= 0) {
    // Do something
}

....since strings are sort of arrays themselves. :)

If needed, implement the indexof function for Internet Explorer as described before me.

Since most for loops are very similar, Java provides a shortcut to reduce the amount of code required to write the loop called the for each loop.

Here is an example of the concise for each loop:

for (Integer grade : quizGrades){
      System.out.println(grade);
 }    

In the example above, the colon (:) can be read as "in". The for each loop altogether can be read as "for each Integer element (called grade) in quizGrades, print out the value of grade."

It's a hard question to answer without more information. There are a number of things you should consider when looking at implementing commenting on an existing website.

How will you address the issue of spam? It doesn't matter how remote your website is, spammers WILL find it and they'll filled it up in no time. You may want to look into something like reCAPTCHA (http://recaptcha.net/).

The structure of the website may also influence how you implement your comments. Are the comments for the overall site, a particular product or page, or even another comment? You'll need to know the relationship between the content and the comment so you can properly define the relationship in the database. To put it another way, you know you want an email address, the comment, and whether it is approved or not, but now we need a way to identify what, if anything, the comment is linked to.

If your site is already established and built on a PHP framework (CakePHP for instance) you'll need to address how to integrate your code properly with what is already in place.

Lastly, there are a number of resources and tutorials on the web for PHP. If you do a quick google search for something along the lines of "PHP blog tutorial" I'm sure you'll find hundreds and the majority will show you step by step how to implement comments.

I have added a distribution to the Python Package Index which makes the match_hostname() function from the Python 3.2 ssl package available on previous versions of Python.

http://pypi.python.org/pypi/backports.ssl_match_hostname/

You can install it with:

pip install backports.ssl_match_hostname

Or you can make it a dependency listed in your project's setup.py. Either way, it can be used like this:

from backports.ssl_match_hostname import match_hostname, CertificateError
...
sslsock = ssl.wrap_socket(sock, ssl_version=ssl.PROTOCOL_SSLv3,
                      cert_reqs=ssl.CERT_REQUIRED, ca_certs=...)
try:
    match_hostname(sslsock.getpeercert(), hostname)
except CertificateError, ce:
    ...

I'll make my point very clear: a singleton with parameters is not a singleton.

A singleton, by definition, is an object you want to be instantiated no more than once. If you are trying to feed parameters to the constructor, what is the point of the singleton?

You have two options. If you want your singleton to be initialized with some data, you may load it with data after instantiation, like so:

SingletonObj singleton = SingletonObj.getInstance();
singleton.init(paramA, paramB); // init the object with data

If the operation your singleton is performing is recurring, and with different parameters every time, you might as well pass the parameters to the main method being executed:

SingletonObj singleton = SingletonObj.getInstance();
singleton.doSomething(paramA, paramB); // pass parameters on execution

In any case, instantiation will always be parameter-less. Otherwise your singleton is not a singleton.

I've had to do something like this when using commons-httpclient to access an internal https server with a self-signed certificate. Yes, our solution was to create a custom TrustManager that simply passed everything (logging a debug message).

This comes down to having our own SSLSocketFactory that creates SSL sockets from our local SSLContext, which is set up to have only our local TrustManager associated with it. You don't need to go near a keystore/certstore at all.

So this is in our LocalSSLSocketFactory:

static {
    try {
        SSL_CONTEXT = SSLContext.getInstance("SSL");
        SSL_CONTEXT.init(null, new TrustManager[] { new LocalSSLTrustManager() }, null);
    } catch (NoSuchAlgorithmException e) {
        throw new RuntimeException("Unable to initialise SSL context", e);
    } catch (KeyManagementException e) {
        throw new RuntimeException("Unable to initialise SSL context", e);
    }
}

public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
    LOG.trace("createSocket(host => {}, port => {})", new Object[] { host, new Integer(port) });

    return SSL_CONTEXT.getSocketFactory().createSocket(host, port);
}

Along with other methods implementing SecureProtocolSocketFactory. LocalSSLTrustManager is the aforementioned dummy trust manager implementation.

You mention adding the additional include directory (C/C++|General) and additional lib dependency (Linker|Input), but have you also added the additional library directory (Linker|General)?

Including a sample error message might also help people answer the question since it's not even clear if the error is during compilation or linking.

The best way is to use fixtures.

Note: Keep in mind that fixtures do direct inserts and don't use your model so if you have callbacks that populate data you will need to find a workaround.

This approach from Microsoft works very well and provides the option to compare one list to another and switch them to get the difference in each. If you are comparing classes simply add your objects to two separate lists and then run the comparison.

SELECT only retrieves data from the database, it does not change the table itself.

If you write

SELECT a AS b FROM x

"b" is just an alias name in the query. It does not create an extra column. Your result in the example would only contain one column named "b". But the column in the table would stay "a". "b" is just another name.

I don't really understand what you mean with "so I can use it with each item later on". Do you mean later in the select statement or later in your application. Perhaps you could provide some example code.

It's been said elaborately, just as "the short answer":

• static variable (class)
  lifetime = program runtime (1)
  visibility = determined by access modifiers (private/protected/public)

• static variable (global scope)
  lifetime = program runtime (1)
  visibility = the compilation unit it is instantiated in (2)

• heap variable
  lifetime = defined by you (new to delete)
  visibility = defined by you (whatever you assign the pointer to)

• stack variable
  visibility = from declaration until scope is exited
  lifetime = from declaration until declaring scope is exited

(1) more exactly: from initialization until deinitialization of the compilation unit (i.e. C / C++ file). Order of initialization of compilation units is not defined by the standard.

(2) Beware: if you instantiate a static variable in a header, each compilation unit gets its own copy.

You may need an extra "/"

I'm fairly sure the primary monitor is the default. If the app was coded decently, when it's closed, it'll remember where it was last at and will reopen there, but -- as you've noticed -- it isn't a default behavior.

EDIT: The way I usually do it is to have the location stored in the app's settings. On load, if there is no value for them, it defaults to the center of the screen. On closing of the form, it records its position. That way, whenever it opens, it's where it was last. I don't know of a simple way to tell it to launch onto the second monitor the first time automatically, however.

@Tim's answer only does half the work -- that gets it into a datetime.datetime object.

To get it into the string format you require, you use datetime.strftime:

I was getting the same error when trying to copy a file. Closing a channel associated with the target file solved the problem.

Path destFile = Paths.get("dest file");
SeekableByteChannel destFileChannel = Files.newByteChannel(destFile);
//...
destFileChannel.close();  //removing this will throw java.nio.file.AccessDeniedException:
Files.copy(Paths.get("source file"), destFile);

As Thomas Owens pointed out, simply concatenating the files will leave multiple ID3 headers scattered throughout the resulting concatenated file - so the time/bitrate info will be wildly wrong.

You're going to need to use a tool which can combine the audio data for you.

mp3wrap would be ideal for this - it's designed to join together MP3 files, without needing to decode + re-encode the data (which would result in a loss of audio quality) and will also deal with the ID3 tags intelligently.

The resulting file can also be split back into its component parts using the mp3splt tool - mp3wrap adds information to the IDv3 comment to allow this.

if you have a string of date, then you should try this.

const FORMAT = "YYYY ddd MMM DD HH:mm";

const theDate = moment("2019 Tue Apr 09 13:30", FORMAT);
// Tue Apr 09 2019 13:30:00 GMT+0300

const theDate1 = moment("2019 Tue Apr 09 13:30", FORMAT).format('LL')
// April 9, 2019

or try this :

const theDate1 = moment("2019 Tue Apr 09 13:30").format(FORMAT);

   <input id="fileupload" name="myfile" type="file" />
   <input type="submit" value="submit" id="submit" />

To upload a file, it is essential to set enctype="multipart/form-data" on your form

You need that form type and then some php to process the file :)

You should probably check out Uploadify if you want something very customisable out of the box.

Simple and short answer to your question is

Please add following line into your "Execute shell" Build step.

#!/bin/sh

Now let me explain you the reason why we require this line for "Execute Shell" build job.

By default Jenkins take /bin/sh -xe and this means -x will print each and every command.And the other option -e, which causes shell to stop running a script immediately when any command exits with non-zero (when any command fails) exit code.

So by adding the #!/bin/sh will allow you to execute with no option.

This maybe what you're looking for:

awk 'BEGIN {FS=" ";} {printf "'\''%s'\'' ", $1}'

That is, with '\'' you close the opening ', then print a literal ' by escaping it and finally open the ' again.

Starting from Xcode 8, you can use the class property attribute as answered by Berbie.

However, in the implementation, you need to define both class getter and setter for the class property using a static variable in lieu of an iVar.

Sample.h

@interface Sample: NSObject
@property (class, retain) Sample *sharedSample;
@end

Sample.m

@implementation Sample
static Sample *_sharedSample;
+ ( Sample *)sharedSample {
   if (_sharedSample==nil) {
      [Sample setSharedSample:_sharedSample];
   }
   return _sharedSample;
}

+ (void)setSharedSample:(Sample *)sample {
   _sharedSample = [[Sample alloc]init];
}
@end

One advantage you get with the approach mentioned by @Tom is that you don't have to create any constructors in the SomeManager, and hence limiting the clients to instantiate it.

@RunWith(MockitoJUnitRunner.class)
public class SomeManagerTest {

    @InjectMocks
    private SomeManager someManager;

    @Mock
    private SomeDependency someDependency; // this will be injected into someManager

    //You don't need to instantiate the SomeManager with default contructor at all
   //SomeManager someManager = new SomeManager();    
   //Or SomeManager someManager = new SomeManager(someDependency);

     //tests...

}

Whether its a good practice or not depends on your application design.

And it works, thanks @trichetriche. The problem was in my RequestOptions, apparently, you can not pass params or body to the RequestOptions while using the post. Removing one of them gives me an error, removing both and it works. Still no final solution to my problem, but I now have something to work with. Final working code.

public post(cmd: string, data: string): Observable<any> {

    const options = new RequestOptions({
      headers: this.getAuthorizedHeaders(),
      responseType: ResponseContentType.Json,
      withCredentials: false
    });

    console.log('Options: ' + JSON.stringify(options));

    return this.http.post(this.BASE_URL, JSON.stringify({
      cmd: cmd,
      data: data}), options)
      .map(this.handleData)
      .catch(this.handleError);
  }

Here's a minor update to the solution provided by Dave Sexton. Many times you need multiple filters. The Filter parameter can only take a single string whereas the -Include parameter can take a string array. if you have a large file tree it also makes sense to only get the date to compare with once, not for each file. Here's my updated version:

$compareDate = (Get-Date).AddDays(-3)    
@(Get-ChildItem -Path c:\pstbak\*.* -Filter '*.pst','*.mdb' -Recurse | Where-Object { $_.LastWriteTime -gt $compareDate}).Count

This error usually means that the target machine is running, but the service that you're trying to connect to is not available. (Either it stopped, crashed, or is busy with another request.)

In English: The connection to the machine (remote host/server/PC that the service runs at) was made but since the service was not available on that machine, the machine didn't know what to do with the request.

If the connection to the machine was not available, you'd see a different error. I forget what it is, but it's along the lines of "Service Unreachable" or "Unavailable".

Edit - added

It IS possible that this is being caused by a firewall blocking the port, but given that you say it's intermittent ("sometimes when the client tries to connect"), that's very unlikely. I didn't include that originally because I had ruled it out mentally before replying.

Rather than using if statements might I suggest using a switch instead, I try to avoid using if statements when possible.

var result = MessageBox.Show(@"Do you want to save the changes?", "Confirmation", MessageBoxButtons.YesNoCancel);
switch (result)
{
    case DialogResult.Yes:
        SaveChanges();
        break;
    case DialogResult.No:
        Rollback();
        break;
    default:
        break;
}

I just ran into this problem too. In my case, I was dealing with some images that were not localized and others that were--in multiple languages. A base URL didn't get the images inside localized folders for me. I solved this by doing the following:

// make sure you have the image name and extension (for demo purposes, I'm using "myImage" and "png" for the file "myImage.png", which may or may not be localized)
NSString *imageFileName = @"myImage";
NSString *imageFileExtension = @"png";

// load the path of the image in the main bundle (this gets the full local path to the image you need, including if it is localized and if you have a @2x version)
NSString *imagePath = [[NSBundle mainBundle] pathForResource:imageFileName ofType:imageFileExtension];

// generate the html tag for the image (don't forget to use file:// for local paths)
NSString *imgHTMLTag = [NSString stringWithFormat:@"<img src=\"file://%@\" />", imagePath];

Then, use imgHTMLTag in your UIWebView HTML code when you load the contents.

I hope this helps anyone who ran into the same problem.

    });
}

It looks like on load, it finds all inputs with autofill, adds their outerHTML and removes the original, while preserving value and name (easily changed to preserve ID etc)

If this preserves the autofill text, you could just set

var text = "";   /* $(this).val(); */

From the original form where this was posted, it claims to preserve autocomplete. :)

Good luck!

I have to say I was quite surprised that HttpContext is null inside the constructor. I'm sure it's for performance reasons. Have confirmed that using IPrincipal as described below does get it injected into the constructor. Its essentially doing the same as the accepted answer, but in a more interfacey-way.

For anyone finding this question looking for an answer to the generic "How to get current user?" you can just access User directly from Controller.User. But you can only do this inside action methods (I assume because controllers don't only run with HttpContexts and for performance reasons).

However - if you need it in the constructor (as OP did) or need to create other injectable objects that need the current user then the below is a better approach:

Inject IPrincipal to get user

First meet IPrincipal and IIdentity

public interface IPrincipal
{
    IIdentity Identity { get; }
    bool IsInRole(string role);
}

public interface IIdentity
{
    string AuthenticationType { get; }
    bool IsAuthenticated { get; }
    string Name { get; }
}

IPrincipal and IIdentity represents the user and username. Wikipedia will comfort you if 'Principal' sounds odd.

Important to realize that whether you get it from IHttpContextAccessor.HttpContext.User, ControllerBase.User or ControllerBase.HttpContext.User you're getting an object that is guaranteed to be a ClaimsPrincipal object which implements IPrincipal.

There's no other type of User that ASP.NET uses for User right now, (but that's not to say other something else couldn't implement IPrincipal).

So if you have something which has a dependency of 'the current user name' that you want injected you should be injecting IPrincipal and definitely not IHttpContextAccessor.

Important: Don't waste time injecting IPrincipal directly to your controller, or action method - it's pointless since User is available to you there already.

In startup.cs:

   // Inject IPrincipal
   services.AddTransient<IPrincipal>(provider => provider.GetService<IHttpContextAccessor>().HttpContext.User);

Then in your DI object that needs the user you just inject IPrincipal to get the current user.

The most important thing here is if you're doing unit tests you don't need to send in an HttpContext, but only need to mock something that represents IPrincipal which can just be ClaimsPrincipal.

One extra important thing that I'm not 100% sure about. If you need to access the actual claims from ClaimsPrincipal you need to cast IPrincipal to ClaimsPrincipal. This is fine since we know 100% that at runtime it's of that type (since that's what HttpContext.User is). I actually like to just do this in the constructor since I already know for sure any IPrincipal will be a ClaimsPrincipal.

If you're doing mocking, just create a ClaimsPrincipal directly and pass it to whatever takes IPrincipal.

Exactly why there is no interface for IClaimsPrincipal I'm not sure. I assume MS decided that ClaimsPrincipal was just a specialized 'collection' that didn't warrant an interface.

For first 5 lines, simply do:

N=5
with open("data_file", "r") as file:
    for i in range(N):
       print file.next()

You can copy your div like this

$(".package").html($(".button").html())

I want to add my solution to above, maybe it helps someone. When i create a field on a model via Room and do not generate getter/setter for the field. As a result project is not compiling and no clear errors.

To my knowledge the setTimeout function is called asynchronously. What you can do is wrap the entire loop within an async function and await a Promise that contains the setTimeout as shown:

var looper = async function () {
  for (var start = 1; start < 10; start++) {
    await new Promise(function (resolve, reject) {
      setTimeout(function () {
        console.log("iteration: " + start.toString());
        resolve(true);
      }, 1000);
    });
  }
  return true;
}

And then you call run it like so:

looper().then(function(){
  console.log("DONE!")
});

Please take some time to get a good understanding of asynchronous programming.

This seems to be a recent regression or some strange behavior in typescript. If you have the code:

const result = []

Usually it would be treated as if you wrote:

const result:any[] = []

however, if you have both noImplicitAny FALSE, AND strictNullChecks TRUE in your tsconfig, it is treated as:

const result:never[] = []

This behavior defies all logic, IMHO. Turning on null checks changes the entry types of an array?? And then turning on noImplicitAny actually restores the use of any without any warnings??

When you truly have an array of any, you shouldn't need to indicate it with extra code.

Wikipedia, of all places, actually discusses this.

The idea is to make sure all package names are unique world-wide, by having authors use a variant of a DNS name they own to name the package. For example, the owners of the domain name joda.org created a number of packages whose names begin with org.joda, for example:

• org.joda.time
• org.joda.time.base
• org.joda.time.chrono
• org.joda.time.convert
• org.joda.time.field
• org.joda.time.format

I had to add the .classpath too, form a java project. I made a dummy java project and looked in the workspace for this dummy java project to see what is required. I transferred the two files. profile and .claspath to my checked out, and disconnected source from my subversion server. From then on it turned to a java project from just a plain old project.

I think that every JSON response should contain a property (e.g. {authenticated: false}) and the client has to test it everytime: if false, then the Angular controller/service will "redirect" to the login page.

And what happen if the user catch de JSON and change the bool to True?

I think you should never rely on client side to do these kind of stuff. If the user is not authenticated, the server should just redirect to a login/error page.

Verry Easy, change order of element:

Origin

<div style="">

    My Text

    <button type="button" style="float: right; margin:5px;">
       My Button
    </button>

</div>

Change to:

<div style=""> 

    <button type="button" style="float: right; margin:5px;">
       My Button
     </button>

   My Text

</div>

You can also take advantage of the built-in Service Parameters system, which lets you isolate or reuse the value:

# app/config/parameters.yml
parameters:
    ga_tracking: UA-xxxxx-x

# app/config/config.yml
twig:
    globals:
        ga_tracking: "%ga_tracking%"

Now, the variable ga_tracking is available in all Twig templates:

<p>The google tracking code is: {{ ga_tracking }}</p>

The parameter is also available inside the controllers:

$this->container->getParameter('ga_tracking');

You can also define a service as a global Twig variable (Symfony2.2+):

# app/config/config.yml
twig:
    # ...
    globals:
        user_management: "@acme_user.user_management"

http://symfony.com/doc/current/templating/global_variables.html

If the global variable you want to set is more complicated - say an object - then you won't be able to use the above method. Instead, you'll need to create a Twig Extension and return the global variable as one of the entries in the getGlobals method.

What you are trying to achieve is equivalent to

interface Event {
   name: string;
   dateCreated: string;
   type: string;
}

interface UserEvent extends Event {
   UserId: string; 
}

The way you defined the types does not allow for specifying inheritance, however you can achieve something similar using intersection types, as artem pointed out.

Span is considered an in-line element. As such is basically constrains itself to the content within it. It more or less is transparent.

Think of it having the behavior of the 'b' tag.

It can be performed like <span style='font-weight: bold;'>bold text</span>

div is a block element.

Google services have a polyglot persistence architecture. BigTable is leveraged by most of its services like YouTube, Google Search, Google Analytics etc. The search service initially used MapReduce for its indexing infrastructure but later transitioned to BigTable during the Caffeine release.

Google Cloud datastore has over 100 applications in production at Google both facing internal and external users. Applications like Gmail, Picasa, Google Calendar, Android Market & AppEngine use Cloud Datastore & Megastore.

Google Trends use MillWheel for stream processing. Google Ads initially used MySQL later migrated to F1 DB - a custom written distributed relational database. Youtube uses MySQL with Vitess. Google stores exabytes of data across the commodity servers with the help of the Google File System.

From Sql 2012 you can force ordering in views and subqueries with OFFSET

SELECT      C.CustomerID,
            C.CustomerName,
            C.CustomerAge
FROM        dbo.Customer C
ORDER BY    CustomerAge OFFSET 0 ROWS;

Warning: this should only be used on small lists because OFFSET forces the full view to be evaluated even if further joins or filters on the view reduce its size!

There is no good way to force ordering in a view without a side effect really and for good reason.

To follow-up on Charles Bailey's answer, here's my git setup that's using p4merge (free cross-platform 3way merge tool); tested on msys Git (Windows) install:

git config --global merge.tool p4merge
git config --global mergetool.p4merge.cmd 'p4merge.exe \"$BASE\" \"$LOCAL\" \"$REMOTE\" \"$MERGED\"'

or, from a windows cmd.exe shell, the second line becomes :

git config --global mergetool.p4merge.cmd "p4merge.exe \"$BASE\" \"$LOCAL\" \"$REMOTE\" \"$MERGED\""

The changes (relative to Charles Bailey):

• added to global git config, i.e. valid for all git projects not just the current one
• the custom tool config value resides in "mergetool.[tool].cmd", not "merge.[tool].cmd" (silly me, spent an hour troubleshooting why git kept complaining about non-existing tool)
• added double quotes for all file names so that files with spaces can still be found by the merge tool (I tested this in msys Git from Powershell)
• note that by default Perforce will add its installation dir to PATH, thus no need to specify full path to p4merge in the command

Download: http://www.perforce.com/product/components/perforce-visual-merge-and-diff-tools

EDIT (Feb 2014)

As pointed out by @Gregory Pakosz, latest msys git now "natively" supports p4merge (tested on 1.8.5.2.msysgit.0).

You can display list of supported tools by running:

git mergetool --tool-help

You should see p4merge in either available or valid list. If not, please update your git.

If p4merge was listed as available, it is in your PATH and you only have to set merge.tool:

git config --global merge.tool p4merge

If it was listed as valid, you have to define mergetool.p4merge.path in addition to merge.tool:

git config --global mergetool.p4merge.path c:/Users/my-login/AppData/Local/Perforce/p4merge.exe

• The above is an example path when p4merge was installed for the current user, not system-wide (does not need admin rights or UAC elevation)
• Although ~ should expand to current user's home directory (so in theory the path should be ~/AppData/Local/Perforce/p4merge.exe), this did not work for me
• Even better would have been to take advantage of an environment variable (e.g. $LOCALAPPDATA/Perforce/p4merge.exe), git does not seem to be expanding environment variables for paths (if you know how to get this working, please let me know or update this answer)

As mentioned by h4z3, For a practical use, Sometimes your data is too big to directly load everything, or you have a generator, or real-time incoming data, you could use w+ to store in a file and read later.

You can do this in-place, rather than create a new dict, which may be preferable for large dictionaries (if you do not need a copy).

def mutate_dict(f,d):
    for k, v in d.iteritems():
        d[k] = f(v)

my_dictionary = {'a':1, 'b':2}
mutate_dict(lambda x: x+1, my_dictionary)

results in my_dictionary containing:

{'a': 2, 'b': 3}

The accepted solution only works on arrays, but not objects or associative arrays. Unfortunately, since Angular depends on the JavaScript implementation of array enumeration, the order of object properties cannot be consistently controlled. Some browsers may iterate through object properties lexicographically, but this cannot be guaranteed.

e.g. Given the following assignment:

$scope.cards = {
  "card2": {
    values: {
      opt1: 9,
      opt2: 12
    }
  },
  "card1": {
    values: {
      opt1: 9,
      opt2: 11
    }
  }
};

and the directive <ul ng-repeat="(key, card) in cards | orderBy:myValueFunction">, ng-repeat may iterate over "card1" prior to "card2", regardless of sort order.

To workaround this, we can create a custom filter to convert the object to an array, and then apply a custom sort function before returning the collection.

myApp.filter('orderByValue', function () {
  // custom value function for sorting
  function myValueFunction(card) {
    return card.values.opt1 + card.values.opt2;
  }

  return function (obj) {
    var array = [];
    Object.keys(obj).forEach(function (key) {
      // inject key into each object so we can refer to it from the template
      obj[key].name = key;
      array.push(obj[key]);
    });
    // apply a custom sorting function
    array.sort(function (a, b) {
      return myValueFunction(b) - myValueFunction(a);
    });
    return array;
  };
});

We cannot iterate over (key, value) pairings in conjunction with custom filters (since the keys for arrays are numerical indexes), so the template should be updated to reference the injected key names.

<ul ng-repeat="card in cards | orderByValue">
    <li>{{card.name}} {{value(card)}}</li>
</ul>

Here is a working fiddle utilizing a custom filter on an associative array: http://jsfiddle.net/av1mLpqx/1/

If you are using Swift, the Just library does this for you. Example from it's readme file:

//  talk to registration end point
Just.post(
    "http://justiceleauge.org/member/register",
    data: ["username": "barryallen", "password":"ReverseF1ashSucks"],
    files: ["profile_photo": .URL(fileURLWithPath:"flash.jpeg", nil)]
) { (r)
    if (r.ok) { /* success! */ }
}

If you want a list of lists:

>>> [list(t) for t in zip(*l)]
[[1, 3, 8], [2, 4, 9]]

If a list of tuples is OK:

>>> zip(*l)
[(1, 3, 8), (2, 4, 9)]

Solution -

1) Upgrade your Selenium Server i.e. selenium jar "selenium-server-standalone-2.xx.x.JAR" TO "selenium-server-standalone-2.45.0.JAR"

2) Upgrade your Selenium Client Driver i.e. selenium libs folder "selenium-java-2.xx.x" TO "selenium-java-2.45.0"

3) Check and Install compatible Firefox version

Is there a way to get it via $event->getComposer()->getRepositoryManager()->getAllPackages()

In C, the compiler is allowed to dictate some alignment for every primitive type. Typically the alignment is the size of the type. But it's entirely implementation-specific.

Padding bytes are introduced so every object is properly aligned. Reordering is not allowed.

Possibly every remotely modern compiler implements #pragma pack which allows control over padding and leaves it to the programmer to comply with the ABI. (It is strictly nonstandard, though.)

From C99 §6.7.2.1:

12 Each non-bit-field member of a structure or union object is aligned in an implementation- defined manner appropriate to its type.

13 Within a structure object, the non-bit-field members and the units in which bit-fields reside have addresses that increase in the order in which they are declared. A pointer to a structure object, suitably converted, points to its initial member (or if that member is a bit-field, then to the unit in which it resides), and vice versa. There may be unnamed padding within a structure object, but not at its beginning.

An inner class is a friend of the class it is defined within.
So, yes; an object of type Outer::Inner can access the member variable var of an object of type Outer.

Unlike Java though, there is no correlation between an object of type Outer::Inner and an object of the parent class. You have to make the parent child relationship manually.

#include <string>
#include <iostream>

class Outer
{
    class Inner
    {
        public:
            Inner(Outer& x): parent(x) {}
            void func()
            {
                std::string a = "myconst1";
                std::cout << parent.var << std::endl;

                if (a == MYCONST)
                {   std::cout << "string same" << std::endl;
                }
                else
                {   std::cout << "string not same" << std::endl;
                }
            }
        private:
            Outer&  parent;
    };

    public:
        Outer()
            :i(*this)
            ,var(4)
        {}
        Outer(Outer& other)
            :i(other)
            ,var(22)
        {}
        void func()
        {
            i.func();
        }
    private:
        static const char* const MYCONST;
        Inner i;
        int var;
};

const char* const Outer::MYCONST = "myconst";

int main()
{

    Outer           o1;
    Outer           o2(o1);
    o1.func();

I have researched this a little and from what I have found you have four options:

Version 1: Parent div with display as table-cell

If you do not mind using the display:table-cell on your parent div, you can use of the following options:

.area{
    height: 100px;
    width: 100px;
    background: red;
    margin:10px;
    text-align: center;
    display:table-cell;
    vertical-align:middle;
}?

Version 2: Parent div with display block and content display table-cell

.area{
    height: 100px;
    width: 100px;
    background: red;
    margin:10px;
    text-align: center;
    display:block;
}

.content {
    height: 100px;
    width: 100px;
    display:table-cell;
    vertical-align:middle;    
}?

Version 3: Parent div floating and content div as display table-cell

.area{
    background: red;
    margin:10px;
    text-align: center;
    display:block;
    float: left;
}

.content {
    display:table-cell;
    vertical-align:middle;
    height: 100px;
    width: 100px;
}?

Live DEMO

Version 4: Parent div position relative with content position absolute

The only problem that I have had with this version is that it seems you will have to create the css for every specific implementation. The reason for this is the content div needs to have the set height that your text will fill and the margin-top will be figured off of that. This issue can be seen in the demo. You can get it to work for every scenario manually by changing the height % of your content div and multiplying it by -.5 to get your margin-top value.

.area{
    position:relative; 
    display:block;
    height:100px;
    width:100px;
    border:1px solid black;
    background:red;
    margin:10px;
}

.content { 
    position:absolute;
    top:50%; 
    height:50%; 
    width:100px;
    margin-top:-25%;
    text-align:center;
}?

It's important to point out that all of the above solutions map the port to every interface on your machine. This is less than desirable if you have a public IP address, or your machine has an IP on a large network. Your application may be exposed to a much wider audience than you'd hoped.

redis:
  build:
    context:
    dockerfile: Dockerfile-redis
    ports:
    - "127.0.0.1:3901:3901"

127.0.0.1 is the ip address that maps to the hostname localhost on your machine. So now your application is only exposed over that interface and since 127.0.0.1 is only accessible via your machine, you're not exposing your containers to the entire world.

The documentation explains this further and can be found here: https://docs.docker.com/compose/compose-file/#ports

Note: If you're using Docker for mac this will make the container listen on 127.0.0.1 on the Docker for Mac VM and will not be accessible from your localhost. If I recall correctly.

since python 3.5 you can use * iterable unpacking operator:

user_list = [*your_iterator]

but the pythonic way to do it is:

user_list  = list(your_iterator)

Branch with short hash and last comment:

git branch -v

  develop      717c2f9 [ahead 42] blabla
* master       2722bbe [ahead 1] bla

To make things simple, here is how you can get just the one you want:

Simple:

$headerValue = $_SERVER['HTTP_X_REQUESTED_WITH'];

or when you need to get one at a time:

<?php
/**
 * @param $pHeaderKey
 * @return mixed
 */
function get_header( $pHeaderKey )
{
    // Expanded for clarity.
    $headerKey = str_replace('-', '_', $pHeaderKey);
    $headerKey = strtoupper($headerKey);
    $headerValue = NULL;
    // Uncomment the if when you do not want to throw an undefined index error.
    // I leave it out because I like my app to tell me when it can't find something I expect.
    //if ( array_key_exists($headerKey, $_SERVER) ) {
    $headerValue = $_SERVER[ $headerKey ];
    //}
    return $headerValue;
}
// X-Requested-With mainly used to identify Ajax requests. Most JavaScript frameworks
// send this header with value of XMLHttpRequest, so this will not always be present.
$header_x_requested_with = get_header( 'X-Requested-With' );

The other headers are also in the super global array $_SERVER, you can read about how to get at them here: http://php.net/manual/en/reserved.variables.server.php

To me an advantage/benefit of an interface is that it is more flexible than an abstract class. Since you can only inherit 1 abstract class but you can implement multiple interfaces, changes to a system that inherits an abstract class in many places becomes problematic. If it is inherited in 100 places, a change requires changes to all 100. But, with the interface, you can place the new change in a new interface and just use that interface where its needed (Interface Seq. from SOLID). Additionally, the memory usage seems like it would be less with the interface as an object in the interface example is used just once in memory despite how many places implement the interface.

Using Javascript you can download like this in a simple method

var oReq = new XMLHttpRequest();
// The Endpoint of your server 
var URLToPDF = "https://mozilla.github.io/pdf.js/web/compressed.tracemonkey-pldi-09.pdf";
// Configure XMLHttpRequest
oReq.open("GET", URLToPDF, true);

// Important to use the blob response type
oReq.responseType = "blob";

// When the file request finishes
// Is up to you, the configuration for error events etc.
oReq.onload = function() {
// Once the file is downloaded, open a new window with the PDF
// Remember to allow the POP-UPS in your browser
var file = new Blob([oReq.response], { 
    type: 'application/pdf' 
});

// Generate file download directly in the browser !
saveAs(file, "mypdffilename.pdf");
};

oReq.send();

Download the appropriate APR based tomcat native library for your operating system so that Apache tomcat server can take some advantage of the feature of your OS which is not included by default in tomcat. For windows it will be a .dll file.

I too got the warning while starting the server and you don't have to worry about this if you are testing or developing. This is meant to be on production purposes. After putting the tcnative-1.dll file inside the bin folder of Apache Tomcat 7 following are the output in the stderr file,

Visible gallery changes visibility which is how you get the gallery over other view overlap. the Home sample app has some good examples of this technique.

Changing an element's value can trigger a DOM event. Listeners that respond to events can be used to implement data binding in JavaScript.

For example:

function bindValues(id1, id2) {
  const e1 = document.getElementById(id1);
  const e2 = document.getElementById(id2);
  e1.addEventListener('input', function(event) {
    e2.value = event.target.value;
  });
  e2.addEventListener('input', function(event) {
    e1.value = event.target.value;
  });
}

Here is code and a demo that shows how DOM elements can be bound with each other or with a JavaScript object.

To round down towards negative infinity, use:

rounded=Math.floor(number);

To round down towards zero (if the number can round to a 32-bit integer between -2147483648 and 2147483647), use:

rounded=number|0;

To round down towards zero (for any number), use:

if(number>0)rounded=Math.floor(number);else rounded=Math.ceil(number);

You can always just export the HTML table to an XLS document. Excel does a pretty good job understanding HTML tables.

Another possiblitly is to export the HTML tables as a CSV or TSV file, but you would need to setup the formatting in your code. This isn't too difficult to accomplish.

There's some classes in the Microsoft.Office.Interop that allow you to create an Excel file programatically, but I have always found them to be a little clumsy. You can find a .NET version of creating a spreadsheet here, which should be pretty easy to modify for classic ASP.

As for .NET, I've always liked CarlosAG's Excel XML Writer Library. It has a nice generator so you can setup your Excel file, save it as an XML spreadsheet and it generates the code to do all the formatting and everything. I know it's not classic ASP, but I thought that I would throw it out there.

With what you're trying above, try adding the header:

"Content-Disposition", "attachment; filename=excelTest.xls"

See if that works. Also, I always use this for the content type:

  Response.ContentType = "application/octet-stream"
    Response.ContentType = "application/vnd.ms-excel"

AsyncTask uses a thread pool pattern for running the stuff from doInBackground(). The issue is initially (in early Android OS versions) the pool size was just 1, meaning no parallel computations for a bunch of AsyncTasks. But later they fixed that and now the size is 5, so at most 5 AsyncTasks can run simultaneously. Unfortunately I don't remember in what version exactly they changed that.

UPDATE:

Here is what current (2012-01-27) API says on this:

When first introduced, AsyncTasks were executed serially on a single background thread. Starting with DONUT, this was changed to a pool of threads allowing multiple tasks to operate in parallel. After HONEYCOMB, it is planned to change this back to a single thread to avoid common application errors caused by parallel execution. If you truly want parallel execution, you can use the executeOnExecutor(Executor, Params...) version of this method with THREAD_POOL_EXECUTOR; however, see commentary there for warnings on its use.

DONUT is Android 1.6, HONEYCOMB is Android 3.0.

UPDATE: 2

See the comment by kabuko from Mar 7 2012 at 1:27.

It turns out that for APIs where "a pool of threads allowing multiple tasks to operate in parallel" is used (starting from 1.6 and ending on 3.0) the number of simultaneously running AsyncTasks depends on how many tasks have been passed for execution already, but have not finished their doInBackground() yet.

This is tested/confirmed by me on 2.2. Suppose you have a custom AsyncTask that just sleeps a second in doInBackground(). AsyncTasks use a fixed size queue internally for storing delayed tasks. Queue size is 10 by default. If you start 15 your custom tasks in a row, then first 5 will enter their doInBackground(), but the rest will wait in a queue for a free worker thread. As soon as any of the first 5 finishes, and thus releases a worker thread, a task from the queue will start execution. So in this case at most 5 tasks will run simultaneously. However if you start 16 your custom tasks in a row, then first 5 will enter their doInBackground(), the rest 10 will get into the queue, but for the 16th a new worker thread will be created so it'll start execution immediately. So in this case at most 6 tasks will run simultaneously.

There is a limit of how many tasks can be run simultaneously. Since AsyncTask uses a thread pool executor with limited max number of worker threads (128) and the delayed tasks queue has fixed size 10, if you try to execute more than 138 your custom tasks the app will crash with java.util.concurrent.RejectedExecutionException.

Starting from 3.0 the API allows to use your custom thread pool executor via AsyncTask.executeOnExecutor(Executor exec, Params... params) method. This allows, for instance, to configure the size of the delayed tasks queue if default 10 is not what you need.

As @Knossos mentions, there is an option to use AsyncTaskCompat.executeParallel(task, params); from support v.4 library to run tasks in parallel without bothering with API level. This method became deprecated in API level 26.0.0.

UPDATE: 3

Here is a simple test app to play with number of tasks, serial vs. parallel execution: https://github.com/vitkhudenko/test_asynctask

UPDATE: 4 (thanks @penkzhou for pointing this out)

Starting from Android 4.4 AsyncTask behaves differently from what was described in UPDATE: 2 section. There is a fix to prevent AsyncTask from creating too many threads.

Before Android 4.4 (API 19) AsyncTask had the following fields:

private static final int CORE_POOL_SIZE = 5;
private static final int MAXIMUM_POOL_SIZE = 128;
private static final BlockingQueue<Runnable> sPoolWorkQueue =
        new LinkedBlockingQueue<Runnable>(10);

In Android 4.4 (API 19) the above fields are changed to this:

private static final int CPU_COUNT = Runtime.getRuntime().availableProcessors();
private static final int CORE_POOL_SIZE = CPU_COUNT + 1;
private static final int MAXIMUM_POOL_SIZE = CPU_COUNT * 2 + 1;
private static final BlockingQueue<Runnable> sPoolWorkQueue =
        new LinkedBlockingQueue<Runnable>(128);

This change increases the size of the queue to 128 items and reduces the maximum number of threads to the number of CPU cores * 2 + 1. Apps can still submit the same number of tasks.

Sample usage while creating a table:

[ColumnName]     BIT   NULL   DEFAULT 0

$("#closeLink").click(closeIt);

Let's say you want to call your function passing some args to it i.e., closeIt(1, false). Then, you should build an anonymous function and call closeIt from it.

$("#closeLink").click(function() {
    closeIt(1, false);
});

Jokab's answer helped me a lot but in my case I could not push to github until I logged in my github account to my git bash so i ran the following commands

git config credential.helper store

then

git push http://github.com/[user name]/[repo name].git

After the second command a GUI window appeared, I provided my login credentials and it worked for me.

Yes, Javascript always passes by value, but in an array or object, the value is a reference to it, so you can 'change' the contents.

But, I think you already read it on SO; here you have the documentation you want:

I had issues installing Express on Ubuntu:

If for some reason NPM command is missing, test npm command with npm help. If not there, follow these steps - http://arnolog.net/post/8424207595/installing-node-js-npm-express-mongoose-on-ubuntu

If just the Express command is not working, try:

sudo npm install -g express

This made everything work as I'm used to with Windows7 and OSX.

Hope this helps!

Thank you!

I was having the same problem:
Sources directory is already NetBeans project (maybe only in memory).

Netbeans creates a folder in your project named "nbproject". Once you delete that, restart the IDE and you're good to go.

This code worked for me:

$(function(){

    $('input:radio').change(function(){
        alert('changed');   
    });          

});

You have install nodeJs on your system in order to execute npm commands. Once npm is properly working you can visit bower.io. There you will find complete documentation on this topic. You will find a command $ npm install bower. this will install bower on your machine. After installing bower you can install Bootstrap easily.

Here is a video tutorial on that

If you are using Java 8+, use java.time.LocalDate type instead.

LocalDate now = LocalDate.now();
System.out.println(now.toString());

The output:

2019-05-30

https://docs.oracle.com/javase/8/docs/api/java/time/LocalDate.html

Simply use

java.util.Collections.sort(list)

without String.CASE_INSENSITIVE_ORDER comparator parameter.

In some extent, You CAN trigger HTML5 form validation and show hints to user without submitting the form!

Two button, one for validate, one for submit

Set a onclick listener on the validate button to set a global flag(say justValidate) to indicate this click is intended to check the validation of the form.

And set a onclick listener on the submit button to set the justValidate flag to false.

Then in the onsubmit handler of the form, you check the flag justValidate to decide the returning value and invoke the preventDefault() to stop the form to submit. As you know, the HTML5 form validation(and the GUI hint to user) is preformed before the onsubmit event, and even if the form is VALID you can stop the form submit by returning false or invoke preventDefault().

And, in HTML5 you have a method to check the form's validation: the form.checkValidity(), then in you can know if the form is validate or not in your code.

OK, here is the demo: http://jsbin.com/buvuku/2/edit

There are already several solutions provided for this question but I have read and tested most of the code here and I ended up with this solution which is a mix of what I learned here:

The function

The function is bundled here in a Symfony2 bundle but it can be extracted to be used as plain PHP, it only has a dependency with the iconv function that must be enabled:

Filesystem.php:

<?php

namespace COil\Bundle\COilCoreBundle\Component\HttpKernel\Util;

use Symfony\Component\HttpKernel\Util\Filesystem as BaseFilesystem;

/**
 * Extends the Symfony filesystem object.
 */
class Filesystem extends BaseFilesystem
{
    /**
     * Make a filename safe to use in any function. (Accents, spaces, special chars...)
     * The iconv function must be activated.
     *
     * @param string  $fileName       The filename to sanitize (with or without extension)
     * @param string  $defaultIfEmpty The default string returned for a non valid filename (only special chars or separators)
     * @param string  $separator      The default separator
     * @param boolean $lowerCase      Tells if the string must converted to lower case
     *
     * @author COil <https://github.com/COil>
     * @see    http://stackoverflow.com/questions/2668854/sanitizing-strings-to-make-them-url-and-filename-safe
     *
     * @return string
     */
    public function sanitizeFilename($fileName, $defaultIfEmpty = 'default', $separator = '_', $lowerCase = true)
    {
    // Gather file informations and store its extension
    $fileInfos = pathinfo($fileName);
    $fileExt   = array_key_exists('extension', $fileInfos) ? '.'. strtolower($fileInfos['extension']) : '';

    // Removes accents
    $fileName = @iconv('UTF-8', 'us-ascii//TRANSLIT', $fileInfos['filename']);

    // Removes all characters that are not separators, letters, numbers, dots or whitespaces
    $fileName = preg_replace("/[^ a-zA-Z". preg_quote($separator). "\d\.\s]/", '', $lowerCase ? strtolower($fileName) : $fileName);

    // Replaces all successive separators into a single one
    $fileName = preg_replace('!['. preg_quote($separator).'\s]+!u', $separator, $fileName);

    // Trim beginning and ending seperators
    $fileName = trim($fileName, $separator);

    // If empty use the default string
    if (empty($fileName)) {
        $fileName = $defaultIfEmpty;
    }

    return $fileName. $fileExt;
    }
}

The unit tests

What is interesting is that I have created PHPUnit tests, first to test edge cases and so you can check if it fits your needs: (If you find a bug, feel free to add a test case)

FilesystemTest.php:

<?php

namespace COil\Bundle\COilCoreBundle\Tests\Unit\Helper;

use COil\Bundle\COilCoreBundle\Component\HttpKernel\Util\Filesystem;

/**

 */
class FilesystemTest extends \PHPUnit_Framework_TestCase
{
    /**
     * test sanitizeFilename()
     */
    public function testFilesystem()
    {
    $fs = new Filesystem();

    $this->assertEquals('logo_orange.gif', $fs->sanitizeFilename('--logö  _  __   ___   ora@@ñ--~gé--.gif'), '::sanitizeFilename() handles complex filename with specials chars');
    $this->assertEquals('coilstack', $fs->sanitizeFilename('cOiLsTaCk'), '::sanitizeFilename() converts all characters to lower case');
    $this->assertEquals('cOiLsTaCk', $fs->sanitizeFilename('cOiLsTaCk', 'default', '_', false), '::sanitizeFilename() lower case can be desactivated, passing false as the 4th argument');
    $this->assertEquals('coil_stack', $fs->sanitizeFilename('coil stack'), '::sanitizeFilename() convert a white space to a separator');
    $this->assertEquals('coil-stack', $fs->sanitizeFilename('coil stack', 'default', '-'), '::sanitizeFilename() can use a different separator as the 3rd argument');
    $this->assertEquals('coil_stack', $fs->sanitizeFilename('coil          stack'), '::sanitizeFilename() removes successive white spaces to a single separator');
    $this->assertEquals('coil_stack', $fs->sanitizeFilename('       coil stack'), '::sanitizeFilename() removes spaces at the beginning of the string');
    $this->assertEquals('coil_stack', $fs->sanitizeFilename('coil   stack         '), '::sanitizeFilename() removes spaces at the end of the string');
    $this->assertEquals('coilstack', $fs->sanitizeFilename('coil,,,,,,stack'), '::sanitizeFilename() removes non-ASCII characters');
    $this->assertEquals('coil_stack', $fs->sanitizeFilename('coil_stack  '), '::sanitizeFilename() keeps separators');
    $this->assertEquals('coil_stack', $fs->sanitizeFilename(' coil________stack'), '::sanitizeFilename() converts successive separators into a single one');
    $this->assertEquals('coil_stack.gif', $fs->sanitizeFilename('cOil Stack.GiF'), '::sanitizeFilename() lower case filename and extension');
    $this->assertEquals('copy_of_coil.stack.exe', $fs->sanitizeFilename('Copy of coil.stack.exe'), '::sanitizeFilename() keeps dots before the extension');
    $this->assertEquals('default.doc', $fs->sanitizeFilename('____________.doc'), '::sanitizeFilename() returns a default file name if filename only contains special chars');
    $this->assertEquals('default.docx', $fs->sanitizeFilename('     ___ -  --_     __%%%%__¨¨¨***____      .docx'), '::sanitizeFilename() returns a default file name if filename only contains special chars');
    $this->assertEquals('logo_edition_1314352521.jpg', $fs->sanitizeFilename('logo_edition_1314352521.jpg'), '::sanitizeFilename() returns the filename untouched if it does not need to be modified');
    $userId = rand(1, 10);
    $this->assertEquals('user_doc_'. $userId. '.doc', $fs->sanitizeFilename('?????.doc', 'user_doc_'. $userId), '::sanitizeFilename() returns the default string (the 2nd argument) if it can\'t be sanitized');
    }
}

I was trying to do this on Drupal 7 with the " fb_likebox" module (https://drupal.org/project/fb_likebox). To get it to be responsive. Turns out I had to write my own Contrib module Variation and stripe out the width setting option. (the default height option didn't matter for me). Once I removed the width, I added the <div id="likebox-wrapper"> in the fb_likebox.tpl.php.

Here's my CSS to style it:

 `#likebox-wrapper * {
  width: 100% !important;
  background: url('../images/block.png') repeat 0 0;
  color: #fbfbfb;
 -webkit-border-radius: 7px;
  -moz-border-radius: 7px;
   -o-border-radius: 7px;
  border-radius: 7px;
   border: 1px solid #DDD;}`

Sub systemcmd(ByVal cmd As String)
    Shell("cmd /c """ & cmd & """", AppWinStyle.MinimizedFocus, True)
End Sub

you can pickle your dict and save as string.

import pickle
import redis

r = redis.StrictRedis('localhost')
mydict = {1:2,2:3,3:4}
p_mydict = pickle.dumps(mydict)
r.set('mydict',p_mydict)

read_dict = r.get('mydict')
yourdict = pickle.loads(read_dict)

maxFiles: 1 does the job but if you also want to remove the additional files you can use this sample code taken from the Wiki page:

How can I limit the number of files?

You're in luck! Starting with 3.7.0 Dropzone supports the maxFiles option. Simply set it to the desired quantity and you're good to go. If you don't want the rejected files to be viewed, simply register for the maxfilesexceeded event, and remove the file immediately:

myDropzone.on("maxfilesexceeded", function(file)
{
    this.removeFile(file);
});

I got this issue because I accidentally imported the .m instead of the .h. Hope reading this saves someone with same problem some time.

I have a lot of issues with most of the answers posted - they either use deprecated libraries that have been ported over with limited features, or provide a solution with too much magic on the execution of the request, making it difficult to error handle. If they do not fall into one of the above categories, they're 3rd party libraries or deprecated.

Some of the solutions works alright purely in http requests, but the solutions fall short for any other kind of request, which is ludicrous. A highly customized solution is not necessary here.

Simply using the python built-in library asyncio is sufficient enough to perform asynchronous requests of any type, as well as providing enough fluidity for complex and usecase specific error handling.

import asyncio

loop = asyncio.get_event_loop()

def do_thing(params):
    async def get_rpc_info_and_do_chores(id):
        # do things
        response = perform_grpc_call(id)
        do_chores(response)

    async def get_httpapi_info_and_do_chores(id):
        # do things
        response = requests.get(URL)
        do_chores(response)

    async_tasks = []
    for element in list(params.list_of_things):
       async_tasks.append(loop.create_task(get_chan_info_and_do_chores(id)))
       async_tasks.append(loop.create_task(get_httpapi_info_and_do_chores(ch_id)))

    loop.run_until_complete(asyncio.gather(*async_tasks))

How it works is simple. You're creating a series of tasks you'd like to occur asynchronously, and then asking a loop to execute those tasks and exit upon completion. No extra libraries subject to lack of maintenance, no lack of functionality required.

if x is a vector with raw scores then scale(x) is a vector with standardized scores.

Or manually: (x-mean(x))/sd(x)

If the file does not exists, open(name,'r+') will fail.

You can use open(name, 'w'), which creates the file if the file does not exist, but it will truncate the existing file.

Alternatively, you can use open(name, 'a'); this will create the file if the file does not exist, but will not truncate the existing file.

One of the nicest things about git is that you don't need to track file renames explicitly. Git will figure it out by comparing the contents of the files.

So, in your case, don't work so hard:

$ mkdir include
$ mv common include
$ git rm -r common
$ git add include/common

Running git status should show you something like this:

$ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   renamed:    common/file.txt -> include/common/file.txt
#

I'm doing like that:

$('<div/>',{
    text: 'Div text',
    class: 'className'
}).appendTo('#parentDiv');

Don't give up so quickly, because this can be done (in modern browsers) using parts of the FileAPI:

var xhr = new XMLHttpRequest();
xhr.open('POST', url, true);
xhr.responseType = 'blob';
xhr.onload = function () {
    if (this.status === 200) {
        var blob = this.response;
        var filename = "";
        var disposition = xhr.getResponseHeader('Content-Disposition');
        if (disposition && disposition.indexOf('attachment') !== -1) {
            var filenameRegex = /filename[^;=\n]*=((['"]).*?\2|[^;\n]*)/;
            var matches = filenameRegex.exec(disposition);
            if (matches != null && matches[1]) filename = matches[1].replace(/['"]/g, '');
        }

        if (typeof window.navigator.msSaveBlob !== 'undefined') {
            // IE workaround for "HTML7007: One or more blob URLs were revoked by closing the blob for which they were created. These URLs will no longer resolve as the data backing the URL has been freed."
            window.navigator.msSaveBlob(blob, filename);
        } else {
            var URL = window.URL || window.webkitURL;
            var downloadUrl = URL.createObjectURL(blob);

            if (filename) {
                // use HTML5 a[download] attribute to specify filename
                var a = document.createElement("a");
                // safari doesn't support this yet
                if (typeof a.download === 'undefined') {
                    window.location.href = downloadUrl;
                } else {
                    a.href = downloadUrl;
                    a.download = filename;
                    document.body.appendChild(a);
                    a.click();
                }
            } else {
                window.location.href = downloadUrl;
            }

            setTimeout(function () { URL.revokeObjectURL(downloadUrl); }, 100); // cleanup
        }
    }
};
xhr.setRequestHeader('Content-type', 'application/x-www-form-urlencoded');
xhr.send($.param(params, true));

Or if using jQuery.ajax:

$.ajax({
    type: "POST",
    url: url,
    data: params,
    xhrFields: {
        responseType: 'blob' // to avoid binary data being mangled on charset conversion
    },
    success: function(blob, status, xhr) {
        // check for a filename
        var filename = "";
        var disposition = xhr.getResponseHeader('Content-Disposition');
        if (disposition && disposition.indexOf('attachment') !== -1) {
            var filenameRegex = /filename[^;=\n]*=((['"]).*?\2|[^;\n]*)/;
            var matches = filenameRegex.exec(disposition);
            if (matches != null && matches[1]) filename = matches[1].replace(/['"]/g, '');
        }

        if (typeof window.navigator.msSaveBlob !== 'undefined') {
            // IE workaround for "HTML7007: One or more blob URLs were revoked by closing the blob for which they were created. These URLs will no longer resolve as the data backing the URL has been freed."
            window.navigator.msSaveBlob(blob, filename);
        } else {
            var URL = window.URL || window.webkitURL;
            var downloadUrl = URL.createObjectURL(blob);

            if (filename) {
                // use HTML5 a[download] attribute to specify filename
                var a = document.createElement("a");
                // safari doesn't support this yet
                if (typeof a.download === 'undefined') {
                    window.location.href = downloadUrl;
                } else {
                    a.href = downloadUrl;
                    a.download = filename;
                    document.body.appendChild(a);
                    a.click();
                }
            } else {
                window.location.href = downloadUrl;
            }

            setTimeout(function () { URL.revokeObjectURL(downloadUrl); }, 100); // cleanup
        }
    }
});

Beware of adding an unwanted timezone to your results, especially if the date is going to be sent out via a Web API. Use UtcNow instead, to make it timezone-less.

try using dedicated functions from high level programming languages. JavaScript .getSeconds(); suits here:

var specifiedTime = new Date("November 02, 2017 06:00:00");
var specifiedTimeSeconds = specifiedTime.getSeconds(); 

var currentTime = new Date();
var currentTimeSeconds = currentTime.getSeconds(); 

alert(specifiedTimeSeconds-currentTimeSeconds);

<?php echo substr("abcabcabc", 0, -3); ?>

If you can use Groovy (which runs on the JVM):

def list = ['a', 'b', 'c', 'd']
println list.join(',')

All credit to Rajeev Kumar's answer, but I received a list of anonymous type that evaluated to string, which was not as easy to iterate over. Updating the code as below helped to return a List that was more easy to manipulate (or, for example, drop straight into a foreach block).

var distinctIds = datatable.AsEnumerable().Select(row => row.Field<string>("id")).Distinct().ToList();

You can't style a disabled checkbox directly because it's controlled by the browser / OS.

However you can be clever and replace the checkbox with a label that simulates a checkbox using pure CSS. You need to have an adjacent label that you can use to style a new "pseudo checkbox". Essentially you're completely redrawing the thing but it gives you complete control over how it looks in any state.

I've thrown up a basic example so that you can see it in action: http://jsfiddle.net/JohnSReid/pr9Lx5th/3/

Here's the sample:

input[type="checkbox"] {_x000D_
    display: none;_x000D_
}_x000D_
_x000D_
label:before {_x000D_
    background: linear-gradient(to bottom, #fff 0px, #e6e6e6 100%) repeat scroll 0 0 rgba(0, 0, 0, 0);_x000D_
    border: 1px solid #035f8f;_x000D_
    height: 36px;_x000D_
    width: 36px;_x000D_
    display: block;_x000D_
    cursor: pointer;_x000D_
}_x000D_
input[type="checkbox"] + label:before {_x000D_
    content: '';_x000D_
    background: linear-gradient(to bottom, #e6e6e6 0px, #fff 100%) repeat scroll 0 0 rgba(0, 0, 0, 0);_x000D_
    border-color: #3d9000;_x000D_
    color: #96be0a;_x000D_
    font-size: 38px;_x000D_
    line-height: 35px;_x000D_
    text-align: center;_x000D_
}_x000D_
_x000D_
input[type="checkbox"]:disabled + label:before {_x000D_
    border-color: #eee;_x000D_
    color: #ccc;_x000D_
    background: linear-gradient(to top, #e6e6e6 0px, #fff 100%) repeat scroll 0 0 rgba(0, 0, 0, 0);_x000D_
}_x000D_
_x000D_
input[type="checkbox"]:checked + label:before {_x000D_
    content: '?';_x000D_
}

<div><input id="cb1" type="checkbox" disabled checked /><label for="cb1"></label></div>_x000D_
<div><input id="cb2" type="checkbox" disabled /><label for="cb2"></label></div>_x000D_

Depending on your level of browser compatibility and accessibility, some additional tweaks will need to be made.

It is possible and you don't need to code it on your own.

Just set the ringer volume to zero and vibration to none if incomingNumber equals an empty string. Thats it ...

Its just done for you with the application Nostalk from Android Market. Just give it a try ...

Although systemd indeed does not provide way to pass command-line arguments for unit files, there are possibilities to write instances: http://0pointer.de/blog/projects/instances.html

For example: /lib/systemd/system/[email protected] looks something like this:

[Unit]
Description=Serial Getty on %I
BindTo=dev-%i.device
After=dev-%i.device systemd-user-sessions.service

[Service]
ExecStart=-/sbin/agetty -s %I 115200,38400,9600
Restart=always
RestartSec=0

So, you may start it like:

$ systemctl start [email protected]
$ systemctl start [email protected]

For systemd it will different instances:

$ systemctl status [email protected]
[email protected] - Getty on ttyUSB0
      Loaded: loaded (/lib/systemd/system/[email protected]; static)
      Active: active (running) since Mon, 26 Sep 2011 04:20:44 +0200; 2s ago
    Main PID: 5443 (agetty)
      CGroup: name=systemd:/system/[email protected]/ttyUSB0
          + 5443 /sbin/agetty -s ttyUSB0 115200,38400,9600

It also mean great possibility enable and disable it separately.

Off course it lack much power of command line parsing, but in common way it is used as some sort of config files selection. For example you may look at Fedora [email protected]: http://pkgs.fedoraproject.org/cgit/openvpn.git/tree/[email protected]

To Whom, deailing with share hosting environment and still chance to have Current PHP less than 7.0 Who does not have dirname( __FILE__, 2 ); it is possible to use following.

function dirname_safe($path, $level = 0){
    $dir = explode(DIRECTORY_SEPARATOR, $path);
    $level = $level * -1;
    if($level == 0) $level = count($dir);
    array_splice($dir, $level);
    return implode($dir, DIRECTORY_SEPARATOR).DIRECTORY_SEPARATOR;
}

print_r(dirname_safe(__DIR__, 2));

I know this is not an answer to this question, but I came across it when searching for a solution to my problem.

In my case, the complex type was not being bound but I was not doing a POST, I was doing a GET with querystring parameters. The solution was to add [FromUri] to the arg:

public class MyController : ApiController
{
    public IEnumerable<MyModel> Get([FromUri] MyComplexType input)
    {
        // input is not null as long as [FromUri] is present in the method arg
    }
}

To avoid an input with only spaces, use: "[a-zA-Z0-9]+[a-zA-Z0-9 ]+".

eg: abc | abc aBc | abc 123 AbC 938234

To ensure, for example, that a first AND last name are entered, use a slight variation like

"[a-zA-Z]+[ ][a-zA-Z]+"

eg: abc def

I think you would like to learn ajax first, try this: Ajax Tutorial

If you want to know how ajax works, it is not a good way to use jQuery directly. I support to learn the native way to send a ajax request to the server, see something about XMLHttpRequest:

var xhr = new XMLHttpReuqest();
xhr.open("GET", "http://some.com");

xhr.onreadystatechange = handler; // do something here...
xhr.send();

You can try this too:

public class Match
{
    [Key]
    public int MatchId { get; set; }

    [ForeignKey("HomeTeam"), Column(Order = 0)]
    public int? HomeTeamId { get; set; }
    [ForeignKey("GuestTeam"), Column(Order = 1)]
    public int? GuestTeamId { get; set; }

    public float HomePoints { get; set; }
    public float GuestPoints { get; set; }
    public DateTime Date { get; set; }

    public virtual Team HomeTeam { get; set; }
    public virtual Team GuestTeam { get; set; }
}

When you make a FK column allow NULLS, you are breaking the cycle. Or we are just cheating the EF schema generator.

In my case, this simple modification solve the problem.

Simple solution would be as below. This is improvement of solution from vale.

private void dgMapTable_SelectionChanged(object sender, EventArgs e) 
{
    int active_map=0;
    if(dgMapTable.SelectedRows.Count>0)
        active_map = dgMapTable.SelectedRows[0].Index;
    // User code if required Process_ROW(active_map);
}

Note for other reader, for above code to work FullRowSelect selection mode for datagridview should be used. You may extend this to give message if more than two rows selected.

I think you probably should not use ternary operator in php. Consider next example:

<?php

function f1($n) {
    var_dump("first funct");
    return $n == 1;
}

function f2($n) {
    var_dump("second funct");
    return $n == 2;
}


$foo = 1;
$a = (f1($foo)) ? "uno" : (f2($foo)) ? "dos" : "tres";
print($a);

How do you think, what $a variable will contain? (hint: dos) And it will remain the same even if $foo variable will be assigned to 2.

To make things better you should either refuse to using this operator or surround right part with braces in the following way:

$a = (f1($foo)) ? "uno" : ((f2($foo)) ? "dos" : "tres");

I came here with a similar question/problem, but I only needed a single value to be stored from the query, not an array/table of results as in the orig post. I was able to use the table method above for a single value, however I have stumbled upon an easier way to store a single value.

declare @myVal int; set @myVal = isnull((select a from table1), 0);

Make sure to default the value in the isnull statement to a valid type for your variable, in my example the value in table1 that we're storing is an int.

This is an example of how to set time in a div(only_time) using javascript.

function date_time() {
    var date = new Date();
    var am_pm = "AM";
    var hour = date.getHours();
    if(hour>=12){
        am_pm = "PM";
    }
    if (hour == 0) {
        hour = 12;
    }
    if(hour>12){
        hour = hour - 12;
    }
    if(hour<10){
        hour = "0"+hour;
    }

    var minute = date.getMinutes();
    if (minute<10){
        minute = "0"+minute;
    }
    var sec = date.getSeconds();
    if(sec<10){
        sec = "0"+sec;
    }

    document.getElementById("time").innerHTML =  hour+":"+minute+":"+sec+" "+am_pm;
}
setInterval(date_time,500);
<per>
<div class="date" id="time"></div>
</per>

The easiest way to do it, at least for me:

git fetch origin <branchName> # Will fetch the branch locally
git checkout <branchName> # To move to that branch

You can simply use jQuery UI Dialog

Example:

$(function() {_x000D_
  $("#dialog").dialog();_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<html lang="en">_x000D_
_x000D_
<head>_x000D_
  <meta charset="utf-8" />_x000D_
  <title>jQuery UI Dialog - Default functionality</title>_x000D_
  <link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css" />_x000D_
  <script src="http://code.jquery.com/ui/1.10.3/jquery-ui.js"></script>_x000D_
  <link rel="stylesheet" href="/resources/demos/style.css" />_x000D_
</head>_x000D_
_x000D_
<body>_x000D_
  <div id="dialog" title="Basic dialog">_x000D_
    <p>This is the default dialog which is useful for displaying information. The dialog window can be moved, resized and closed with the 'x' icon.</p>_x000D_
  </div>_x000D_
</body>_x000D_
</html>

This worked for me

sudo apt install openjdk-8-jre-headless

I found this to be a lot easier

from dateutil import relativedelta
relativedelta.relativedelta(end_time,start_time).seconds

You can do the following to install java 8 on your machine. First get the link of tar that you want to install. You can do this by:

1. go to java downloads page and find the appropriate download.
2. Accept the license agreement and download it.
3. In the download page in your browser right click and copy link address.

Then in your terminal:

$ cd /tmp
$ wget http://download.oracle.com/otn-pub/java/jdk/8u74-b02/jdk-8u74-linux-x64.tar.gz\?AuthParam\=1458001079_a6c78c74b34d63befd53037da604746c
$ tar xzf jdk-8u74-linux-x64.tar.gz?AuthParam=1458001079_a6c78c74b34d63befd53037da604746c
$ sudo mv jdk1.8.0_74 /opt
$ cd /opt/jdk1.8.0_74/
$ sudo update-alternatives --install /usr/bin/java java /opt/jdk1.8.0_91/bin/java 2
$ sudo update-alternatives --config java // select version
$ sudo update-alternatives --install /usr/bin/jar jar /opt/jdk1.8.0_91/bin/jar 2
$ sudo update-alternatives --install /usr/bin/javac javac /opt/jdk1.8.0_91/bin/javac 2
$ sudo update-alternatives --set jar /opt/jdk1.8.0_91/bin/jar
$ sudo update-alternatives --set javac /opt/jdk1.8.0_74/bin/javac
$ java -version // you should have the updated java

int fun(int n_args, ...) {
   int *p = &n_args; 
   int s = sizeof(int);
   p += s + s - 1;
   for(int i = 0; i < n_args; i++) {
     printf("A1 %d!\n", *p);
     p += 2;
   }
}

Plain version

set a style for the image

<asp:Image ID="Image1" runat="server" style="max-height:1000px;max-width:900px;height:auto;width:auto;" />

var app=angular.module('myApp',[]);
        app.controller('myController',function($scope){         
              $scope.names = ['1288323623006','1388323623006'];

        });

Here Controller name is "myController" and app name is "myApp".

<div ng-app="myApp" ng-controller="myController">
        <ul>
            <li ng-repeat="x in names">
                {{x | date:'mm-dd-yyyy'}}

            </li>

        </ul>
    </div>

Result will look like this :- * 10-29-2010 * 01-03-2013

None of the above solutions worked for me on Windows 8

But the following command works fine

SHIFT + Q

I had a similar problem with R-studio. When I tried to do my plots, this message was showing up.

Eventually I realised that the reason behind this was that my "window" for the plots was too small, and I had to make it bigger to "fit" all the plots inside!

Hope to help

Wikipedia is built on MediaWiki, and here's the MediaWiki API.

Your formula is wrong. You probably meant something like:

=IF(AND(NOT(ISBLANK(Q2));NOT(ISBLANK(R2)));IF(Q2<=R2;"1";"0");"")

Another equivalent:

=IF(NOT(OR(ISBLANK(Q2);ISBLANK(R2)));IF(Q2<=R2;"1";"0");"")

Or even shorter:

=IF(OR(ISBLANK(Q2);ISBLANK(R2));"";IF(Q2<=R2;"1";"0"))

OR EVEN SHORTER:

=IF(OR(ISBLANK(Q2);ISBLANK(R2));"";--(Q2<=R2))

The statement you're executing is valid. The error seems to mean that Toad is including the trailing semicolon as part of the command, which does cause an ORA-00911 when it's included as part of a statement - since it is a statement separator in the client, not part of the statement itself.

It may be the following commented-out line that is confusing Toad (as described here); or it might be because you're trying to run everything as a single statement, in which case you can try to use the run script command (F9) instead of run statement (F5).

Just removing the commented-out line makes the problem go away, but if you also saw this with an actual commit then it's likely to be that you're using the wrong method to run the statements.

There is a bit more information about how Toad parses the semicolons in a comment on this related question, but I'm not familiar enough with Toad to go into more detail.

There are several methods given in Laravel for checking results count/check empty/not empty:

$result->isNotEmpty(); // True if result is not empty.
$result->isEmpty(); // True if result is empty.
$result->count(); // Return count of records in result.

It's much easier (and faster) to get this information by only parsing the output of ver:

@echo off
setlocal
for /f "tokens=4-5 delims=. " %%i in ('ver') do set VERSION=%%i.%%j
if "%version%" == "10.0" echo Windows 10
if "%version%" == "6.3" echo Windows 8.1
if "%version%" == "6.2" echo Windows 8.
if "%version%" == "6.1" echo Windows 7.
if "%version%" == "6.0" echo Windows Vista.
rem etc etc
endlocal

This table on MSDN documents which version number corresponds to which Windows product version (this is where you get the 6.1 means Windows 7 information from).

The only drawback of this technique is that it cannot distinguish between the equivalent server and consumer versions of Windows.

First of all, you tried to replace the entire 12.00 with '', which isn't going to give your desired results.

Second you are trying to do replace directly on a decimal. Replace must be performed on a string, so you have to CAST.

There are many ways to get your desired results, but this replace would have worked (assuming your column name is "height":

REPLACE(CAST(height as varchar(31)),'.00','')

EDIT:

This script works:

DECLARE @Height decimal(6,2);
SET @Height = 12.00;
SELECT @Height, REPLACE(CAST(@Height AS varchar(31)),'.00','');

Use the in keyword to test if a attribute is defined in a object

if (assoc_var in assoc_pagine)

OR

if ("home" in assoc_pagine)

There are quite a few issues here.

Firstly, is var supposed to a variable has the value "home", "work" or "about"? Or did you mean to inspect actual property called "var"?

If var is supposed to be a variable that has a string value, please note that var is a reserved word in JavaScript and you will need to use another name, such as assoc_var.

var assoc_var = "home";
assoc_pagine[assoc_var] // equals 0 in your example

If you meant to inspect the property called "var", then you simple need to put it inside of quotes.

assoc_pagine["var"]

Then, undefined is not the same as "undefined". You will need typeof to get the string representation of the objects type.

This is a breakdown of all the steps.

var assoc_var = "home"; 
var value = assoc_pagine[assoc_var]; // 0
var typeofValue = typeof value; // "number"

So to fix your problem

if (typeof assoc_pagine[assoc_var] != "undefined") 

update: As other answers have indicated, using a array is not the best sollution for this problem. Consider using a Object instead.

var assoc_pagine = new Object();
assoc_pagine["home"]=0;
assoc_pagine["about"]=1;
assoc_pagine["work"]=2;

This may be overkill for what you require, but I found this library to be very helpful:

http://fittextjs.com/

It's only good for single lines though, so I'm not certain if that fits your requirement.

you don't need to set the width of header in css, just put the background image as center using this code:

background: url("images/logo.png") no-repeat top center;

or you can just use img tag and put align="center" in the div

Try the Properties Maven Plugin

A little late to the game here, but I was running into some performance issues with HYRY's solution, so I had to come up with another one.

It works by finding the frequency of each key-value, and then, for each key, only keeping the value that appears with it most often.

There's also an additional solution that supports multiple modes.

On a scale test that's representative of the data I'm working with, this reduced runtime from 37.4s to 0.5s!

Here's the code for the solution, some example usage, and the scale test:

import numpy as np
import pandas as pd
import random
import time

test_input = pd.DataFrame(columns=[ 'key',          'value'],
                          data=  [[ 1,              'A'    ],
                                  [ 1,              'B'    ],
                                  [ 1,              'B'    ],
                                  [ 1,              np.nan ],
                                  [ 2,              np.nan ],
                                  [ 3,              'C'    ],
                                  [ 3,              'C'    ],
                                  [ 3,              'D'    ],

This approach with ViewGroup.MarginLayoutParams worked for me:

RelativeLayout myLayout = (RelativeLayout) findViewById(R.id.my_layout);

TextView someTextView = ...

int leftMargin = Util.getXPos();
int topMargin = Util.getYPos();

RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
    new ViewGroup.MarginLayoutParams(
        RelativeLayout.LayoutParams.WRAP_CONTENT,
        RelativeLayout.LayoutParams.WRAP_CONTENT));

lp.setMargins(leftMargin, topMargin, 0, 0);

myLayout.addView(someTextView, lp);

It turns out that Google Android ships with Apache HttpClient 4.0, and I was able to figure out how to do it using the "Form based logon" example in the HttpClient docs:

You can do that with some easy jQuery:

http://jsfiddle.net/jpXjH/6/

var elementPosition = $('#navigation').offset();

$(window).scroll(function(){
        if($(window).scrollTop() > elementPosition.top){
              $('#navigation').css('position','fixed').css('top','0');
        } else {
            $('#navigation').css('position','static');
        }    
});

For those who had trouble with the apt-get, or with the long instruction. I solved it in a relatively painless way.

1. Download the installer from here, or direct download link
2. $ sudo dpkg -i oracle-java8-installer_8u51+8u51arm-1-webupd8-0_all.deb

You've got a few things going on there. One, why a class? Do you actually have multiple of these on the page? The CSS suggests you can't. If not you should use an ID - it's faster to select both in CSS and jQuery:

<div id=bottomMenu>You read it all.</div>

Second you've got a few crazy things going on in that CSS - in particular the z-index is supposed to just be a number, not measured in pixels. It specifies what layer this tag is on, where each higher number is closer to the user (or put another way, on top of/occluding tags with lower z-indexes).

The animation you're trying to do is basically .fadeIn(), so just set the div to display: none; initially and use .fadeIn() to animate it:

$('#bottomMenu').fadeIn(2000);

.fadeIn() works by first doing display: (whatever the proper display property is for the tag), opacity: 0, then gradually ratcheting up the opacity.

Full working example:

http://jsfiddle.net/b9chris/sMyfT/

CSS:

#bottomMenu {
    display: none;
    position: fixed;
    left: 0; bottom: 0;
    width: 100%; height: 60px;
    border-top: 1px solid #000;
    background: #fff;
    z-index: 1;
}

JS:

var $win = $(window);

function checkScroll() {
    if ($win.scrollTop() > 100) {
        $win.off('scroll', checkScroll);
        $('#bottomMenu').fadeIn(2000);
    }
}

$win.scroll(checkScroll);

For the block element not occupy the whole line, set it's width to something small and the white-space:nowrap

label
{
    width:10px;
    display:block;
    white-space:nowrap;
}

const is like let, it is a LexicalDeclaration (VariableStatement, Declaration) used to define an identifier in your block.

You are trying to mix this with the default keyword, which expects a HoistableDeclaration, ClassDeclaration or AssignmentExpression to follow it.

Therefore it is a SyntaxError.

If you want to const something you need to provide the identifier and not use default.

export by itself accepts a VariableStatement or Declaration to its right.

AFAIK the export in itself should not add anything to your current scope.

The following is fineexport default Tab;

Tab becomes an AssignmentExpression as it's given the name default ^?

export default Tab = connect( mapState, mapDispatch )( Tabs ); is fine

Here Tab = connect( mapState, mapDispatch )( Tabs ); is an AssignmentExpression.

Left, Right and Below tabs were removed from Bootstrap 3, but you can add custom CSS to achieve this..

UPDATE

If you don't need the exact look of a tab (bordered appropriately on the left or right as each tab is activated), you can simple use nav-stacked, along with Bootstrap col-* to float the tabs to the left or right...

nav-stacked demo: http://codeply.com/go/rv3Cvr0lZ4

<ul class="nav nav-pills nav-stacked col-md-3">
    <li><a href="#a" data-toggle="tab">1</a></li>
    <li><a href="#b" data-toggle="tab">2</a></li>
    <li><a href="#c" data-toggle="tab">3</a></li>
</ul>

I am assuming what you are trying to achieve is to insert a line after the first few lines of of a textfile.

head -n10 file.txt >> newfile.txt
echo "your line >> newfile.txt
tail -n +10 file.txt >> newfile.txt

If you don't want to rest of the lines from the file, just skip the tail part.

Not exactly php, but you could exec a program from php to convert the pdf to a temporary html file and then parse the resulting file with php. I've done something similar for a project of mine and this is the program I used:

PdfToHtml

The resulting HTML wraps text elements in < div > tags with absolute position coordinates. It seems like this is exactly what you are trying to do.

Use SequenceEqual to check for sequence equality because Equals method checks for reference equality.

var a = ints1.SequenceEqual(ints2);

Or if you don't care about elements order use Enumerable.All method:

var a = ints1.All(ints2.Contains);

The second version also requires another check for Count because it would return true even if ints2 contains more elements than ints1. So the more correct version would be something like this:

var a = ints1.All(ints2.Contains) && ints1.Count == ints2.Count;

In order to check inequality just reverse the result of All method:

var a = !ints1.All(ints2.Contains)

There's no pretty way. You might be able to use a proxy with the handler having the target methods and delegating everything else to them. Of course you'll have to use a factory because there'll be no constructor.

When nesting repetition operators, make absolutely sure that there is only one way to match the same match.

As hinted at in yatima2975's answer, there is an additional difference:

substr() accepts a negative starting position as an offset from the end of the string. substring() does not.

From MDN:

If start is negative, substr() uses it as a character index from the end of the string.

So to sum up the functional differences:

substring(begin-offset, end-offset-exclusive) where begin-offset is 0 or greater

substr(begin-offset, length) where begin-offset may also be negative

Here's a detailed explanation about the calculation of MaxClients and MaxRequestsPerChild

http://web.archive.org/web/20160415001028/http://www.genericarticles.com/mediawiki/index.php?title=How_to_optimize_apache_web_server_for_maximum_concurrent_connections_or_increase_max_clients_in_apache

ServerLimit 16
StartServers 2
MaxClients 200
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25

First of all, whenever an apache is started, it will start 2 child processes which is determined by StartServers parameter. Then each process will start 25 threads determined by ThreadsPerChild parameter so this means 2 process can service only 50 concurrent connections/clients i.e. 25x2=50. Now if more concurrent users comes, then another child process will start, that can service another 25 users. But how many child processes can be started is controlled by ServerLimit parameter, this means that in the configuration above, I can have 16 child processes in total, with each child process can handle 25 thread, in total handling 16x25=400 concurrent users. But if number defined in MaxClients is less which is 200 here, then this means that after 8 child processes, no extra process will start since we have defined an upper cap of MaxClients. This also means that if I set MaxClients to 1000, after 16 child processes and 400 connections, no extra process will start and we cannot service more than 400 concurrent clients even if we have increase the MaxClient parameter. In this case, we need to also increase ServerLimit to 1000/25 i.e. MaxClients/ThreadsPerChild=40 So this is the optmized configuration to server 1000 clients

<IfModule mpm_worker_module>
    ServerLimit          40
    StartServers          2
    MaxClients          1000
    MinSpareThreads      25
    MaxSpareThreads      75 
    ThreadsPerChild      25
    MaxRequestsPerChild   0
</IfModule>

The following worked for me against a SQL Azure backend (using SQL Server Management Studio), so YMMV, but, if it works for you, it's waaaaay simpler than the other solutions.

ALTER TABLE MyTable
    DROP CONSTRAINT FK_MyColumn
    CONSTRAINT DK_MyColumn
    -- etc...
    COLUMN MyColumn
GO

You can also search with -- option which basically ignores all the special characters and it won't be interpreted by grep.

$ cat foo |grep -- "0\.49"

To reflect the status as of 2015:

Behaviorally both 400 and 422 response codes will be treated the same by clients and intermediaries, so it actually doesn't make a concrete difference which you use.

However I would expect to see 400 currently used more widely, and furthermore the clarifications that the HTTPbis spec provides make it the more appropriate of the two status codes:

• The HTTPbis spec clarifies the intent of 400 to not be solely for syntax errors. The broader phrase "indicates that the server cannot or will not process the request due to something which is perceived to be a client error" is now used.
• 422 is specifically a WebDAV extension, and is not referenced in RFC 2616 or in the newer HTTPbis specification.

For context, HTTPbis is a revision of the HTTP/1.1 spec that attempts to clarify areas that were unclear or inconsistent. Once it has reached approved status it will supersede RFC2616.

Or, you can declare input number as long, and then let it do the code tango :D ...

public static void main(String[] args) {

    Scanner in = new Scanner(System.in);
    System.out.println("Enter a number");
    long n = in.nextLong();

    for (long i = 2; i <= n; i++) {
        while (n % i == 0) {
            System.out.print(", " + i);
            n /= i;
        }
    }
}

You will need to change JAVA_HOME path to the Java SDK directory instead of the Java RE directory. In Windows you can do this using the set command in a command prompt.

e.g.

set JAVA_HOME="C:\Program Files\Java\jdk1.6.0_14"

Please add this option:

//Boolean - Whether the scale should start at zero, or an order of magnitude down from the lowest value
scaleBeginAtZero : true,

(Reference: Chart.js)

N.B: The original solution I posted was for Highcharts, if you are not using Highcharts then please remove the tag to avoid confusion

None of the above worked for me in Sublime Text 2 on Windows.

I did this:

• click on an empty line;
• drag to the following empty line (selecting the invisible character after the line);
• press ctrl+H for replace;
• input desired replacement character/string or leave it empty;
• click "Replace all";

By selecting before hitting ctrl+H it uses that as the character to be replaced.

You can use the .blur() method. See http://api.jquery.com/blur/

When you want to make your php value storable, you have to turn it to be a string value, that is what serialize() does. And unserialize() does the reverse thing.

You (as in the process that runs b.php, either you through CLI or a webserver) need write access to the directory in which the files are located. You are updating the directory content, so access to the file is not enough.

Note that if you use the PHP chmod() function to set the mode of a file or folder to 777 you should use 0777 to make sure the number is correctly interpreted as an octal number.

You can use pandas.cut:

bins = [0, 1, 5, 10, 25, 50, 100]
df['binned'] = pd.cut(df['percentage'], bins)
print (df)
   percentage     binned
0       46.50   (25, 50]
1       44.20   (25, 50]
2      100.00  (50, 100]
3       42.12   (25, 50]

bins = [0, 1, 5, 10, 25, 50, 100]
labels = [1,2,3,4,5,6]
df['binned'] = pd.cut(df['percentage'], bins=bins, labels=labels)
print (df)
   percentage binned
0       46.50      5
1       44.20      5
2      100.00      6
3       42.12      5

Or numpy.searchsorted:

bins = [0, 1, 5, 10, 25, 50, 100]
df['binned'] = np.searchsorted(bins, df['percentage'].values)
print (df)
   percentage  binned
0       46.50       5
1       44.20       5
2      100.00       6
3       42.12       5

...and then value_counts or groupby and aggregate size:

s = pd.cut(df['percentage'], bins=bins).value_counts()
print (s)
(25, 50]     3
(50, 100]    1
(10, 25]     0
(5, 10]      0
(1, 5]       0
(0, 1]       0
Name: percentage, dtype: int64

s = df.groupby(pd.cut(df['percentage'], bins=bins)).size()
print (s)
percentage
(0, 1]       0
(1, 5]       0
(5, 10]      0
(10, 25]     0
(25, 50]     3
(50, 100]    1
dtype: int64

By default cut return categorical.

Series methods like Series.value_counts() will use all categories, even if some categories are not present in the data, operations in categorical.

It is indeed possible.

Here is an example calling the Weather SOAP Service using plain requests lib:

import requests
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
#headers = {'content-type': 'application/soap+xml'}
headers = {'content-type': 'text/xml'}
body = """<?xml version="1.0" encoding="UTF-8"?>
         <SOAP-ENV:Envelope xmlns:ns0="http://ws.cdyne.com/WeatherWS/" xmlns:ns1="http://schemas.xmlsoap.org/soap/envelope/" 
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
            <SOAP-ENV:Header/>
              <ns1:Body><ns0:GetWeatherInformation/></ns1:Body>
         </SOAP-ENV:Envelope>"""

response = requests.post(url,data=body,headers=headers)
print response.content

Some notes:

• The headers are important. Most SOAP requests will not work without the correct headers. application/soap+xml is probably the more correct header to use (but the weatherservice prefers text/xml
• This will return the response as a string of xml - you would then need to parse that xml.
• For simplicity I have included the request as plain text. But best practise would be to store this as a template, then you can load it using jinja2 (for example) - and also pass in variables.

For example:

from jinja2 import Environment, PackageLoader
env = Environment(loader=PackageLoader('myapp', 'templates'))
template = env.get_template('soaprequests/WeatherSericeRequest.xml')
body = template.render()

Some people have mentioned the suds library. Suds is probably the more correct way to be interacting with SOAP, but I often find that it panics a little when you have WDSLs that are badly formed (which, TBH, is more likely than not when you're dealing with an institution that still uses SOAP ;) ).

You can do the above with suds like so:

from suds.client import Client
url="http://wsf.cdyne.com/WeatherWS/Weather.asmx?WSDL"
client = Client(url)
print client ## shows the details of this service

result = client.service.GetWeatherInformation() 
print result 

Note: when using suds, you will almost always end up needing to use the doctor!

Finally, a little bonus for debugging SOAP; TCPdump is your friend. On Mac, you can run TCPdump like so:

sudo tcpdump -As 0 

This can be helpful for inspecting the requests that actually go over the wire.

The above two code snippets are also available as gists:

• SOAP Request with requests
• SOAP Request with suds

[[ $var =~ ^-?[0-9]+$ ]]

• The ^ indicates the beginning of the input pattern
• The - is a literal "-"
• The ? means "0 or 1 of the preceding (-)"
• The + means "1 or more of the preceding ([0-9])"
• The $ indicates the end of the input pattern

So the regex matches an optional - (for the case of negative numbers), followed by one or more decimal digits.

References:

in Swift 4.2

var nav = self.navigationController?.navigationBar
nav?.barStyle = UIBarStyle.Black
nav?.tintColor = UIColor.white
nav?.titleTextAttributes = [NSForegroundColorAttributeName: UIColor.orange]

You can use jquery.serializeJSON to do this.

Here's a simple, yet powerful example, using the apache class HierarchicalINIConfiguration:

HierarchicalINIConfiguration iniConfObj = new HierarchicalINIConfiguration(iniFile); 

// Get Section names in ini file     
Set setOfSections = iniConfObj.getSections();
Iterator sectionNames = setOfSections.iterator();

while(sectionNames.hasNext()){

 String sectionName = sectionNames.next().toString();

 SubnodeConfiguration sObj = iniObj.getSection(sectionName);
 Iterator it1 =   sObj.getKeys();

    while (it1.hasNext()) {
    // Get element
    Object key = it1.next();
    System.out.print("Key " + key.toString() +  " Value " +  
                     sObj.getString(key.toString()) + "\n");
}

Commons Configuration has a number of runtime dependencies. At a minimum, commons-lang and commons-logging are required. Depending on what you're doing with it, you may require additional libraries (see previous link for details).

1) The command is C:\Program Files\Microsoft SDKs\Windows\v6.0A\bin\sn -T {your.dll}

In the above example, the Microsoft SDK resides in C:\Program Files\Microsoft SDKs\Windows\v6.0A. Your environment may differ.

2) To get the public key token of any of your project, you can add sn.exe as part of your External Tools in Visual Studio. The steps are shown in this Microsoft link: How to: Create a Tool to Get the Public Key of an Assembly

You need to use v-bind: or its alias :. For example,

<a v-bind:href="'/job/'+ r.id">

or

<a :href="'/job/' + r.id">

Based on this HTML5 Doctor diagram, I'm thinking this may be the best markup:

<aside class="sidebar">
    <article id="widget_1" class="widget">...</article>
    <article id="widget_2" class="widget">...</article>
    <article id="widget_3" class="widget">...</article>
</aside> <!-- end .sidebar -->

I think it's clear that <aside> is the appropriate element as long as it's outside the main <article> element.

Now, I'm thinking that <article> is also appropriate for each widget in the aside. In the words of the W3C:

The article element represents a self-contained composition in a document, page, application, or site and that is, in principle, independently distributable or reusable, e.g. in syndication. This could be a forum post, a magazine or newspaper article, a blog entry, a user-submitted comment, an interactive widget or gadget, or any other independent item of content.

You need to find reference of existing Fragment and remove that fragment using below code. You need add/commit fragment using one tag ex. "TAG_FRAGMENT".

Fragment fragment = getSupportFragmentManager().findFragmentByTag(TAG_FRAGMENT);
if(fragment != null)
    getSupportFragmentManager().beginTransaction().remove(fragment).commit();

That is it.

declare @counter as int
set @counter = 0
declare @date as varchar(50)
set @date = cast(1+@counter as varchar)+'/01/2013'
while(@counter < 12)
begin 
select  cast(1+@counter as varchar)+'/01/2013' as date
set @counter = @counter + 1
end

There's little-no documentation on angular for uploading files. A lot of solutions require custom directives other dependencies (jquery in primis... just to upload a file...). After many tries I've found this with just angularjs (tested on v.1.0.6)

<input type="file" name="file" onchange="angular.element(this).scope().uploadFile(this.files)"/>

Angularjs (1.0.6) not support ng-model on "input-file" tags so you have to do it in a "native-way" that pass the all (eventually) selected files from the user.

controller

$scope.uploadFile = function(files) {
    var fd = new FormData();
    //Take the first selected file
    fd.append("file", files[0]);

    $http.post(uploadUrl, fd, {
        withCredentials: true,
        headers: {'Content-Type': undefined },
        transformRequest: angular.identity
    }).success( ...all right!... ).error( ..damn!... );

};

The cool part is the undefined content-type and the transformRequest: angular.identity that give at the $http the ability to choose the right "content-type" and manage the boundary needed when handling multipart data.

As you keep getting pages of results I'm assuming you started the session in SQL*Plus. If so, the easy thing to do is to bash ctrl + break many, many times until it stops.

The more complicated and the more generic way(s) I detail below in order of increasing ferocity / evil. The first one will probably work for you but if it doesn't you can keep moving down the list.

Most of these are not recommended and can have unintended consequences.

1. Oracle level - Kill the process in the database

As per ObiWanKenobi's answer and the ALTER SESSION documentation

alter system kill session 'sid,serial#';

To find the sid, session id, and the serial#, serial number, run the following query - summarised from OracleBase - and find your session:

select s.sid, s.serial#, p.spid, s.username, s.schemaname
     , s.program, s.terminal, s.osuser
  from v$session s
  join v$process p
    on s.paddr = p.addr
 where s.type != 'BACKGROUND'

If you're running a RAC then you need to change this slightly to take into account the multiple instances, inst_id is what identifies them:

select s.inst_id, s.sid, s.serial#, p.spid, s.username
     , s.schemaname, s.program, s.terminal, s.osuser
  from Gv$session s
  join Gv$process p
    on s.paddr = p.addr
   and s.inst_id = p.inst_id
 where s.type != 'BACKGROUND'

This query would also work if you're not running a RAC.

If you're using a tool like PL/SQL Developer then the sessions window will also help you find it.

For a slightly stronger "kill" you can specify the IMMEDIATE keyword, which instructs the database to not wait for the transaction to complete:

alter system kill session 'sid,serial#' immediate;

2. OS level - Issue a SIGTERM

kill pid

This assumes you're using Linux or another *nix variant. A SIGTERM is a terminate signal from the operating system to the specific process asking it to stop running. It tries to let the process terminate gracefully.

Getting this wrong could result in you terminating essential OS processes so be careful when typing.

You can find the pid, process id, by running the following query, which'll also tell you useful information like the terminal the process is running from and the username that's running it so you can ensure you pick the correct one.

select p.*
  from v$process p
  left outer join v$session s
    on p.addr = s.paddr
 where s.sid = ?
   and s.serial# = ?

Once again, if you're running a RAC you need to change this slightly to:

select p.*
  from Gv$process p
  left outer join Gv$session s
    on p.addr = s.paddr
 where s.sid = ?
   and s.serial# = ?

Changing the where clause to where s.status = 'KILLED' will help you find already killed process that are still "running".

3. OS - Issue a SIGKILL

kill -9 pid

Using the same pid you picked up in 2, a SIGKILL is a signal from the operating system to a specific process that causes the process to terminate immediately. Once again be careful when typing.

This should rarely be necessary. If you were doing DML or DDL it will stop any rollback being processed and may make it difficult to recover the database to a consistent state in the event of failure.

All the remaining options will kill all sessions and result in your database - and in the case of 6 and 7 server as well - becoming unavailable. They should only be used if absolutely necessary...

4. Oracle - Shutdown the database

shutdown immediate

This is actually politer than a SIGKILL, though obviously it acts on all processes in the database rather than your specific process. It's always good to be polite to your database.

Shutting down the database should only be done with the consent of your DBA, if you have one. It's nice to tell the people who use the database as well.

It closes the database, terminating all sessions and does a rollback on all uncommitted transactions. It can take a while if you have large uncommitted transactions that need to be rolled back.

5. Oracle - Shutdown the database ( the less nice way )

shutdown abort

This is approximately the same as a SIGKILL, though once again on all processes in the database. It's a signal to the database to stop everything immediately and die - a hard crash. It terminates all sessions and does no rollback; because of this it can mean that the database takes longer to startup again. Despite the incendiary language a shutdown abort isn't pure evil and can normally be used safely.

As before inform people the relevant people first.

6. OS - Reboot the server

reboot

Obviously, this not only stops the database but the server as well so use with caution and with the consent of your sysadmins in addition to the DBAs, developers, clients and users.

7. OS - The last stage

I've had reboot not work... Once you've reached this stage you better hope you're using a VM. We ended up deleting it...

An important point is to consider if you perform tasks based on difference between 2 timestamps because you will get odd behavior if you generate it with gettimeofday(), and even clock_gettime(CLOCK_REALTIME,..) at the moment where you will set the time of your system.

To prevent such problem, use clock_gettime(CLOCK_MONOTONIC_RAW, &tms) instead.

Yes, there are a few of them.

Try this:

ALTER TABLE "table_name"
MODIFY "column_name" "New Data Type";

Try this:

foreach($array as $k => $obj) { 
    $obj->{'newKey'} = "value"; 
}

It sets result to the (unsigned) value resulting from putting the 8 bits of value in the lowest 8 bits of result.

The reason something like this is necessary is that byte is a signed type in Java. If you just wrote:

int result = value;

then result would end up with the value ff ff ff fe instead of 00 00 00 fe. A further subtlety is that the & is defined to operate only on int values¹, so what happens is:

1. value is promoted to an int (ff ff ff fe).
2. 0xff is an int literal (00 00 00 ff).
3. The & is applied to yield the desired value for result.

(The point is that conversion to int happens before the & operator is applied.)

1_{Well, not quite. The & operator works on long values as well, if either operand is a long. But not on byte. See the Java Language Specification, sections 15.22.1 and 5.6.2.}

You don't add columns between other columns in SQL, you just add them. Where they're put is totally up to the DBMS. The right place to ensure that columns come out in the correct order is when you select them.

In other words, if you want them in the order {name,colnew,qty,rate}, you use:

select name, colnew, qty, rate from ...

With SQLite, you need to use alter table, an example being:

alter table mytable add column colnew char(50)

HTML are markup languages, basically they are set of tags like <html>, <body>, which is used to present a website using css, and javascript as a whole. All these, happen in the clients system or the user you will be browsing the website.

Now, Connecting to a database, happens on whole another level. It happens on server, which is where the website is hosted.

So, in order to connect to the database and perform various data related actions, you have to use server-side scripts, like php, jsp, asp.net etc.

Now, lets see a snippet of connection using MYSQLi Extension of PHP

$db = mysqli_connect('hostname','username','password','databasename');

This single line code, is enough to get you started, you can mix such code, combined with HTML tags to create a HTML page, which is show data based pages. For example:

<?php
    $db = mysqli_connect('hostname','username','password','databasename');
?>
<html>
    <body>
          <?php
                $query = "SELECT * FROM `mytable`;";
                $result = mysqli_query($db, $query);
                while($row = mysqli_fetch_assoc($result)) {
                      // Display your datas on the page
                }
          ?>
    </body>
</html>

In order to insert new data into the database, you can use phpMyAdmin or write a INSERT query and execute them.

Use cases are used to document behavior, e.g. answer this question.

A behavior extends another if it is in addition to but not necessarily part of the behavior, e.g. research the answer.

Also note that researching the answer doesn't make much sense if you are not trying to answer the question.

A behavior is included in another if it is part of the including behavior, e.g. login to stack exchange.

To clarify, the illustration is only true if you want to answer here in stack overflow :).

These are the technical definitions from UML 2.5 pages 671-672.

I highlighted what I think are important points.

Extends

An Extend is a relationship from an extending UseCase (the extension) to an extended UseCase (the extendedCase) that specifies how and when the behavior defined in the extending UseCase can be inserted into the behavior defined in the extended UseCase. The extension takes place at one or more specific extension points defined in the extended UseCase.

Extend is intended to be used when there is some additional behavior that should be added, possibly conditionally, to the behavior defined in one or more UseCases.

The extended UseCase is defined independently of the extending UseCase and is meaningful independently of the extending UseCase. On the other hand, the extending UseCase typically defines behavior that may not necessarily be meaningful by itself. Instead, the extending UseCase defines a set of modular behavior increments that augment an execution of the extended UseCase under specific conditions.

...

Includes

Include is a DirectedRelationship between two UseCases, indicating that the behavior of the included UseCase (the addition) is inserted into the behavior of the including UseCase (the includingCase). It is also a kind of NamedElement so that it can have a name in the context of its owning UseCase (the includingCase). The including UseCase may depend on the changes produced by executing the included UseCase. The included UseCase must be available for the behavior of the including UseCase to be completely described.

The Include relationship is intended to be used when there are common parts of the behavior of two or more UseCases. This common part is then extracted to a separate UseCase, to be included by all the base UseCases having this part in common. As the primary use of the Include relationship is for reuse of common parts, what is left in a base UseCase is usually not complete in itself but dependent on the included parts to be meaningful. This is reflected in the direction of the relationship, indicating that the base UseCase depends on the addition but not vice versa.

I was getting this exact error when loading an HTML file on the browser that was using a json file from the local directory. In my case, I was able to solve this by creating a simple node server that allowed to server static content. I left the code for this at this other answer.

Here is an example where pointer to data members could be useful:

#include <iostream>
#include <list>
#include <string>

template <typename Container, typename T, typename DataPtr>
typename Container::value_type searchByDataMember (const Container& container, const T& t, DataPtr ptr) {
    for (const typename Container::value_type& x : container) {
        if (x->*ptr == t)
            return x;
    }
    return typename Container::value_type{};
}

struct Object {
    int ID, value;
    std::string name;
    Object (int i, int v, const std::string& n) : ID(i), value(v), name(n) {}
};

std::list<Object*> objects { new Object(5,6,"Sam"), new Object(11,7,"Mark"), new Object(9,12,"Rob"),
    new Object(2,11,"Tom"), new Object(15,16,"John") };

int main() {
    const Object* object = searchByDataMember (objects, 11, &Object::value);
    std::cout << object->name << '\n';  // Tom
}

Yes, you must open php.ini and remove the semicolon to:

;extension=php_openssl.dll

If you don't have that line, check that you have the file (In my PC is on D:\xampp\php\ext) and add this to php.ini in the "Dynamic Extensions" section:

extension=php_openssl.dll

Things have changed for PHP > 7. This is what i had to do for PHP 7.2.

Step: 1: Uncomment extension=openssl

Step: 2: Uncomment extension_dir = "ext"

Step: 3: Restart xampp.

Done.

Explanation: ( From php.ini )

If you wish to have an extension loaded automatically, use the following syntax:

extension=modulename

Note : The syntax used in previous PHP versions (extension=<ext>.so and extension='php_<ext>.dll) is supported for legacy reasons and may be deprecated in a future PHP major version. So, when it is possible, please move to the new (extension=<ext>) syntax.

Special Note: Be sure to appropriately set the extension_dir directive.

A simple way to do this is

var jsonArray = store.data.items

So if your JSON store is

[{"text": "ABC"}, {"text": "DEF"},{"text": "GHI"},{"text": "JKL"}]

Then you can retreive "DEF" as

jsonArray[1].data.text

In the following code, I noticed that it converts each and every character into an array item.

var jsonData = Ext.encode(Ext.pluck(store.data.items, 'data'));

With pure JavaScript:

console.log(window.location.href)

Using Angular:

this.router.url

import { Component } from '@angular/core';
import { Router } from '@angular/router';

@Component({
    template: 'The href is: {{href}}'
    /*
    Other component settings
    */
})
export class Component {
    public href: string = "";

    constructor(private router: Router) {}

    ngOnInit() {
        this.href = this.router.url;
        console.log(this.router.url);
    }
}

The plunkr is here: https://plnkr.co/edit/0x3pCOKwFjAGRxC4hZMy?p=preview

If your grep supports -R, do:

grep -R 'string' dir/

If not, then use find:

find dir/ -type f -exec grep -H 'string' {} +

Building on Alex's answer, here is a more generic function:

applyToGivenRow = @(func, matrix) @(row) func(matrix(row, :));
newApplyToRows = @(func, matrix) arrayfun(applyToGivenRow(func, matrix), 1:size(matrix,1), 'UniformOutput', false)';
takeAll = @(x) reshape([x{:}], size(x{1},2), size(x,1))';
genericApplyToRows = @(func, matrix) takeAll(newApplyToRows(func, matrix));

Here is a comparison between the two functions:

>> % Example
myMx = [1 2 3; 4 5 6; 7 8 9];
myFunc = @(x) [mean(x), std(x), sum(x), length(x)];
>> genericApplyToRows(myFunc, myMx)

ans =

     2     1     6     3
     5     1    15     3
     8     1    24     3

>> applyToRows(myFunc, myMx)
??? Error using ==> arrayfun
Non-scalar in Uniform output, at index 1, output 1.
Set 'UniformOutput' to false.

Error in ==> @(func,matrix)arrayfun(applyToGivenRow(func,matrix),1:size(matrix,1))'

It appears to be a known issue.

Many IN queries can be re-written as (left outer) joins and an IS (NOT) NULL of some sort. for example

SELECT * FROM FOO WHERE ID IN (SELECT ID FROM FOO2)

can be re-written as

SELECT FOO.* FROM FOO JOIN FOO2 ON FOO.ID=FOO2.ID

or

SELECT * FROM FOO WHERE ID NOT IN (SELECT ID FROM FOO2)

can be

SELECT FOO.* FROM FOO 
LEFT OUTER JOIN FOO2 
ON FOO.ID=FOO2.ID WHERE FOO.ID IS NULL

Swift 3/4 with @IBDesignable

While almost all the above solutions work fine but I would suggest an @IBDesignable custom class for this.

@IBDesignable
class CustomLabel: UILabel {

    /*
    // Only override draw() if you perform custom drawing.
    // An empty implementation adversely affects performance during animation.
    override func draw(_ rect: CGRect) {
        // Drawing code
    }
    */

    @IBInspectable var borderColor: UIColor = UIColor.white {
        didSet {
            layer.borderColor = borderColor.cgColor
        }
    }

    @IBInspectable var borderWidth: CGFloat = 2.0 {
        didSet {
            layer.borderWidth = borderWidth
        }
    }

    @IBInspectable var cornerRadius: CGFloat = 0.0 {
        didSet {
            layer.cornerRadius = cornerRadius
        }
    }
}

Declare the class containing the event:

class MyClass {
    public event EventHandler MyEvent;

    public void Method() {
        OnEvent();
    }

    private void OnEvent() {
        if (MyEvent != null) {
            MyEvent(this, EventArgs.Empty);
        }
    }
}

Use it like this:

MyClass myObject = new MyClass();
myObject.MyEvent += new EventHandler(myObject_MyEvent);
myObject.Method();

No one has clearly mentioned this, but this kind of pattern is usually not suited for semaphores. The reason is that any thread can release a semaphore, but you usually only want the owner thread that originally locked to be able to unlock. For this use case, in Java, we usually use ReentrantLocks, which can be created like this:

import java.util.concurrent.locks.Lock;
import java.util.concurrent.locks.ReentrantLock;

private final Lock lock = new ReentrantLock(true);

And the usual design pattern of usage is:

  lock.lock();
  try {
      // do something
  } catch (Exception e) {
      // handle the exception
  } finally {
      lock.unlock();
  }

Here is an example in the java source code where you can see this pattern in action.

Reentrant locks have the added benefit of supporting fairness.

Use semaphores only if you need non-ownership-release semantics.

Re jcoby's answer:

bytea being a "normal" column also means the value being read completely into memory when you fetch it. Blobs, in contrast, you can stream into stdout. That helps in reducing the server memory footprint. Especially, when you store 4-6 MPix images.

No problem with backing up blobs. pg_dump provides "-b" option to include the large objects into the backup.

So, I prefer using pg_lo_*, you may guess.

Re Kris Erickson's answer:

I'd say the opposite :). When images are not the only data you store, don't store them on the file system unless you absolutely have to. It's such a benefit to be always sure about your data consistency, and to have the data "in one piece" (the DB). BTW, PostgreSQL is great in preserving consistency.

However, true, reality is often too performance-demanding ;-), and it pushes you to serve the binary files from the file system. But even then I tend to use the DB as the "master" storage for binaries, with all the other relations consistently linked, while providing some file system-based caching mechanism for performance optimization.

Because this shows up when you google ajax status 0 I wanted to leave some tip that just took me hours of wasted time... I was using ajax to call a PHP service which happened to be Phil's REST_Controller for Codeigniter (not sure if this has anything to do with it or not) and kept getting status 0, readystate 0 and it was driving me nuts. I was debugging it and noticed when I would echo and return instead of exit the message I'd get a success. Finally I turned debugging off and tried and it worked. Seems the xDebug debugger with PHP was somehow modifying the response. If your using a PHP debugger try turning it off to see if that helps.

First, make sure the listener on database server (computer A) that receives client connection requests is running. To do so, run lsnrctl status command.

In case, if you get TNS:no listener message (see below image), it means listener service is not running. To start it, run lsnrctl start command.

Second, for database operations and connectivity from remote clients, the following executables must be added to the Windows Firewall exception list: (see image)

Oracle_home\bin\oracle.exe - Oracle Database executable

Oracle_home\bin\tnslsnr.exe - Oracle Listener

Finally, install oracle instant client on client machine (computer B) and run:

sqlplus user/password@computerA:port/XE

In Servlet technology if you want to pass any input to a particular servlet then you need to pass in init param like below code.

 <servlet>
    <servlet-name>DBController</servlet-name>
    <servlet-class>com.test.controller.DBController</servlet-class>
    <init-param>
        <param-name>username</param-name>
        <param-value>John</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>DBController</servlet-name>
    <url-pattern>/DBController</url-pattern>
</servlet-mapping>

If you want to pass some in put that is common for all servlets then that time you need to configure context param. Example

 <context-param>
    <param-name>email</param-name>
    <param-value>[email protected]</param-value>
</context-param>

SO exactly like this when ever we are working with Spring MVC we need to provide some information to Predefined servlet provided by Spring that is DispatcherServlet through init param. So the configuration is as fallows, here we are providing the spring-servlet.xml as init parameter to DispatcherServlet.

 <?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee"
        xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
              http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
    id="WebApp_ID" version="3.0">
    <display-name>Spring MVC App</display-name>

    <servlet>
        <servlet-name>SpringController</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/spring-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>SpringController</servlet-name>
        <url-pattern>*.htm</url-pattern>
    </servlet-mapping>
</web-app>

Again we need some context param. That is applicable for whole application. So we can provide the root context that is applicationcontext.xml The configuration is like this:

    <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/applicationcontext.xml</param-value>
</context-param>
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
        <servlet-name>SpringController</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/spring-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>

    <servlet-mapping>
        <servlet-name>SpringController</servlet-name>
        <url-pattern>*.htm</url-pattern>
    </servlet-mapping>

You do not need jQuery just to do this! All you need is a tiny and very light vanilla Javascript and a css class (as in all the answers above) :

• First define a CSS class in your stylesheet called current.

• Second add the following pure JavaScript either in your existing JavaScript file or in a separate js script file (but add script tage link to it in the head of the pages) or event just add it in a script tag just before the closing body tag, it will still work in all these cases.

    function highlightCurrent() {
         const curPage = document.URL;
         const links = document.getElementsByTagName('a');
         for (let link of links) {
           if (link.href == curPage) {
             link.classList.add("current");
           }
         }
       }


       document.onreadystatechange = () => {
         if (document.readyState === 'complete') {
           highlightCurrent()
         }
       };

The 'href' attribute of current link should be the absolute path as given by document.URL (console.log it to make sure it is the same)
