I'm obviosly not a very good R coder, but if you wanted to do this with ggplot2:

data<- rbind(c(480, 780, 431, 295, 670, 360,  190),
             c(720, 350, 377, 255, 340, 615,  345),
             c(460, 480, 179, 560,  60, 735, 1260),
             c(220, 240, 876, 789, 820, 100,   75))

a <- cbind(data[, 1], 1, c(1:4))
b <- cbind(data[, 2], 2, c(1:4))
c <- cbind(data[, 3], 3, c(1:4))
d <- cbind(data[, 4], 4, c(1:4))
e <- cbind(data[, 5], 5, c(1:4))
f <- cbind(data[, 6], 6, c(1:4))
g <- cbind(data[, 7], 7, c(1:4))

data           <- as.data.frame(rbind(a, b, c, d, e, f, g))
colnames(data) <-c("Time", "Type", "Group")
data$Type      <- factor(data$Type, labels = c("A", "B", "C", "D", "E", "F", "G"))

library(ggplot2)

ggplot(data = data, aes(x = Type, y = Time, fill = Group)) + 
       geom_bar(stat = "identity") +
       opts(legend.position = "none")

For every client you need to start separate thread. Example:

public class ThreadedEchoServer {

    static final int PORT = 1978;

    public static void main(String args[]) {
        ServerSocket serverSocket = null;
        Socket socket = null;

        try {
            serverSocket = new ServerSocket(PORT);
        } catch (IOException e) {
            e.printStackTrace();

        }
        while (true) {
            try {
                socket = serverSocket.accept();
            } catch (IOException e) {
                System.out.println("I/O error: " + e);
            }
            // new thread for a client
            new EchoThread(socket).start();
        }
    }
}

and

public class EchoThread extends Thread {
    protected Socket socket;

    public EchoThread(Socket clientSocket) {
        this.socket = clientSocket;
    }

    public void run() {
        InputStream inp = null;
        BufferedReader brinp = null;
        DataOutputStream out = null;
        try {
            inp = socket.getInputStream();
            brinp = new BufferedReader(new InputStreamReader(inp));
            out = new DataOutputStream(socket.getOutputStream());
        } catch (IOException e) {
            return;
        }
        String line;
        while (true) {
            try {
                line = brinp.readLine();
                if ((line == null) || line.equalsIgnoreCase("QUIT")) {
                    socket.close();
                    return;
                } else {
                    out.writeBytes(line + "\n\r");
                    out.flush();
                }
            } catch (IOException e) {
                e.printStackTrace();
                return;
            }
        }
    }
}

You can also go with more advanced solution, that uses NIO selectors, so you will not have to create thread for every client, but that's a bit more complicated.

I just thought I should share how I actually solved the problem and why I think this is the right solution (provided you don't optimize for old browser).

Converting data to dataURL (data: ...)

var blob = new Blob(
              // I'm using page innerHTML as data
              // note that you can use the array
              // to concatenate many long strings EFFICIENTLY
              [document.body.innerHTML],
              // Mime type is important for data url
              {type : 'text/html'}
); 
// This FileReader works asynchronously, so it doesn't lag
// the web application
var a = new FileReader();
a.onload = function(e) {
     // Capture result here
     console.log(e.target.result);
};
a.readAsDataURL(blob);

Allowing user to save data

Apart from obvious solution - opening new window with your dataURL as URL you can do two other things.

1. Use fileSaver.js

File saver can create actual fileSave dialog with predefined filename. It can also fallback to normal dataURL approach.

2. Use (experimental) URL.createObjectURL

This is great for reusing base64 encoded data. It creates a short URL for your dataURL:

console.log(URL.createObjectURL(blob));
//Prints: blob:http://stackoverflow.com/7c18953f-f5f8-41d2-abf5-e9cbced9bc42

Don't forget to use the URL including the leading blob prefix. I used document.body again:

You can use this short URL as AJAX target, <script> source or <a> href location. You're responsible for destroying the URL though:

URL.revokeObjectURL('blob:http://stackoverflow.com/7c18953f-f5f8-41d2-abf5-e9cbced9bc42')

I deleted the entire Config folder but preserved the files repositories.yml repository-cache repository-grouping.yml. after running SmartGit, it created the config folder (i think it used the config from an older build (to save things like my git credentials)), then i copied back my three files and i had all my repositories which is the most important info i needed.

I think your problem may lie in how your datepicker is setup. Why don't you disconnect the input... do not use altField. Instead explicitly set the values when the onSelect fires. This will give you control of each interaction; the user text field, and the datepicker.

Note: Sometimes you have to call the routine on .change() and not .onSelect() because onSelect can be called on different interactions that you are not expecting.

Pseudo Code:

$('#date').datepicker({
    //altField: , //do not use
    onSelect: function(date){
        $('#date').val(date); //Set my textbox value
        //Do your search routine
    },
}).change(function(){
    //Or do it here...
});

$('#date').change(function(){
    var thisDate = $(this).val();
    if(isValidDate(thisDate)){
        $('#date').datepicker('setDate', thisDate); //Set my datepicker value
        //Do your search routine
    });
});

In Java (version 6+), you can also do:

Desktop d = Desktop.getDesktop();
d.browse(uri);

Though this won't work on all Linuxes. At the time of writing, Gnome is supported, KDE isn't.

Make sure you've set your locale settings right before running the script from the shell, e.g.

$ locale -a | grep "^en_.\+UTF-8"
en_GB.UTF-8
en_US.UTF-8
$ export LC_ALL=en_GB.UTF-8
$ export LANG=en_GB.UTF-8

Docs: man locale, man setlocale.

I don't think your question is very clear, this code assumes that if you're going to include the -domain parameter, it's always 'named' (i.e. dostuff computername arg2 -domain domain); this also makes the computername parameter mandatory.

Function DoStuff(){
    param(
        [Parameter(Mandatory=$true)][string]$computername,
        [Parameter(Mandatory=$false)][string]$arg2,
        [Parameter(Mandatory=$false)][string]$domain
    )
    if(!($domain)){
        $domain = 'domain1'
    }
    write-host $domain
    if($arg2){
        write-host "arg2 present... executing script block"
    }
    else{
        write-host "arg2 missing... exiting or whatever"
    }
}

I personally prefer to just get them in one object hash, then I can access them anywhere. This could easily be set to an injectable variable and then everything could have it and it only grabbed once.

By wrapping the function this can also be done as a one liner.

var meta = (function () {
    var m = document.querySelectorAll("meta"), r = {};
    for (var i = 0; i < m.length; i += 1) {
        r[m[i].getAttribute("name")] = m[i].getAttribute("content")
    }
    return r;
})();

Now you can use nameof:

public static void Output<T>(IEnumerable<T> dataSource) where T : class
{
    string dataSourceName = typeof(T).Name;
    switch (dataSourceName)
    {
        case nameof(CustomerDetails):
            var t = 123;
            break;
        default:
            Console.WriteLine("Test");
    }
}

nameof(CustomerDetails) is basically identical to the string literal "CustomerDetails", but with a compile-time check that it refers to some symbol (to prevent a typo).

nameof appeared in C# 6.0, so after this question was asked.

I was receiving the error (I'm using Vue) and I switched my onclick="someFunction()" to @click="someFunction" and now they are working.

Just for educational purposes you could also do it with any of the following ways:

1.

    var query = {"roll": {$gt: 70};
    var cursor = db.student.find(query);
    cursor.project({"roll":1, "_id":0});

2.

    var query = {"roll": {$gt: 70};
    var projection = {"roll":1, "_id":0};
    var cursor = db.student.find(query,projection);

This is Web GUI of a GitHub repository:

Drag and drop your folder to the above area. When you upload too much folder/files, GitHub will notice you:

Yowza, that’s a lot of files. Try again with fewer than 100 files.

and add commit message

And press button Commit changes is the last step.

Best solution IMHO:

in fragment:

protected void addClick(int id) {
    try {
        getView().findViewById(id).setOnClickListener(this);
    } catch (Exception e) {
        e.printStackTrace();
    }
}

public void onClick(View v) {
    if (v.getId()==R.id.myButton) {
        onMyButtonClick(v);
    }
}

then in Fragment's onViewStateRestored:

addClick(R.id.myButton);

In pandas you can do str.len with your boundary and using the Boolean result to filter it .

df[df['column name'].str.len().lt(2)]

Just about every modern operating system will recover all the allocated memory space after a program exits. The only exception I can think of might be something like Palm OS where the program's static storage and runtime memory are pretty much the same thing, so not freeing might cause the program to take up more storage. (I'm only speculating here.)

So generally, there's no harm in it, except the runtime cost of having more storage than you need. Certainly in the example you give, you want to keep the memory for a variable that might be used until it's cleared.

However, it's considered good style to free memory as soon as you don't need it any more, and to free anything you still have around on program exit. It's more of an exercise in knowing what memory you're using, and thinking about whether you still need it. If you don't keep track, you might have memory leaks.

On the other hand, the similar admonition to close your files on exit has a much more concrete result - if you don't, the data you wrote to them might not get flushed, or if they're a temp file, they might not get deleted when you're done. Also, database handles should have their transactions committed and then closed when you're done with them. Similarly, if you're using an object oriented language like C++ or Objective C, not freeing an object when you're done with it will mean the destructor will never get called, and any resources the class is responsible might not get cleaned up.

' \r ' means carriage return.

The \r means nothing special as a consequence.For character-mode terminals (typically emulating even-older printing ones as above), in raw mode, \r and \n act similarly (except both in terms of the cursor, as there is no carriage or roller . Historically a \n was used to move the carriage down, while the \r was used to move the carriage back to the left side of the screen.

As I understand it, the selected answer still loads all of the related tests. According to this msdn blog, there is a better way.

http://blogs.msdn.com/b/adonet/archive/2011/01/31/using-dbcontext-in-ef-feature-ctp5-part-6-loading-related-entities.aspx

Specifically

using (var context = new UnicornsContext())

    var princess = context.Princesses.Find(1);

    // Count how many unicorns the princess owns 
    var unicornHaul = context.Entry(princess)
                      .Collection(p => p.Unicorns)
                      .Query()
                      .Count();
}

Following is the solution which I came up with if there are multiple characters in the string all having the highest frequency.

mystr = input("enter string: ")
#define dictionary to store characters and their frequencies
mydict = {}
#get the unique characters
unique_chars = sorted(set(mystr),key = mystr.index)
#store the characters and their respective frequencies in the dictionary
for c in unique_chars:
    ctr = 0
    for d in mystr:
        if d != " " and d == c:
            ctr = ctr + 1
    mydict[c] = ctr
print(mydict)
#store the maximum frequency
max_freq = max(mydict.values())
print("the highest frequency of occurence: ",max_freq)
#print all characters with highest frequency
print("the characters are:")
for k,v in mydict.items():
    if v == max_freq:
        print(k)

Input: "hello people"

Output:

{'o': 2, 'p': 2, 'h': 1, ' ': 0, 'e': 3, 'l': 3}

the highest frequency of occurence: 3

the characters are:

e

l

I think that you can use

$file= public_path(). "/download/info.pdf";

$headers = array(
        'Content-Type: ' . mime_content_type( $file ),
    );

With this you be sure that is a pdf.

Read the existing answers first, this is just an addendum.

Notice that you can raise exceptions with or without arguments.

Example:

raise SystemExit

exits the program but you might want to know what happened.So you can use this.

raise SystemExit("program exited")

this will print "program exited" to stderr before closing the program.

I need to do the same thing. I ended up with something similar to Kman

       static void ExcelToCSVCoversion(string sourceFile,  string targetFile)
    {
        Application rawData = new Application();

        try
        {
            Workbook workbook = rawData.Workbooks.Open(sourceFile);
            Worksheet ws = (Worksheet) workbook.Sheets[1];
            ws.SaveAs(targetFile, XlFileFormat.xlCSV);
            Marshal.ReleaseComObject(ws);
        }

        finally
        {
            rawData.DisplayAlerts = false;
            rawData.Quit();
            Marshal.ReleaseComObject(rawData);
        }


        Console.WriteLine();
        Console.WriteLine($"The excel file {sourceFile} has been converted into {targetFile} (CSV format).");
        Console.WriteLine();
    }

If there are multiple sheets this is lost in the conversion but you could loop over the number of sheets and save each one as csv.

$(document).ready(function() {
$("#aDateFrom").datepicker({
    onSelect: function() {
        //- get date from another datepicker without language dependencies
        var minDate = $('#aDateFrom').datepicker('getDate');
        $("#aDateTo").datepicker("change", { minDate: minDate });
    }
});

$("#aDateTo").datepicker({
    onSelect: function() {
        //- get date from another datepicker without language dependencies
        var maxDate = $('#aDateTo').datepicker('getDate');
        $("#aDateFrom").datepicker("change", { maxDate: maxDate });
    }
});
});

cant say why, but the es5/6 syntax doesnt work

elem.onclick = (ev) => {console.log(this);} not working

elem.onclick = function(ev) {console.log(this);} working

If you check which string would come first in a lexicon, you've done a lexicographical comparison of the strings!

Some links:

• Wikipedia - String (computer science) Lexicographical ordering
• Note on comparisons: lexicographic comparison between strings

Stolen from the latter link:

A string s precedes a string t in lexicographic order if

• s is a prefix of t, or
• if c and d are respectively the first character of s and t in which s and t differ, then c precedes d in character order.

Note: For the characters that are alphabetical letters, the character order coincides with the alphabetical order. Digits precede letters, and uppercase letters precede lowercase ones.

Example:

• house precedes household
• Household precedes house
• composer precedes computer
• H2O precedes HOTEL

In my case i moved the validate part outside of the document ready function and it works fine for me. I hope it would work for u...

 $(document).ready(function () {

I had same issue, I resolved from below steps:

1. Right click on project->maven->Update project
2. Here I selected "force update for snapshot/release"
3. After that I compiled again my project and issue got fixed

As your methods an int datatype, you should use "==" instead of equals()

try replacing this if (id.equals(list[pos].getItemNumber()))

with

if (id.equals==list[pos].getItemNumber())

it will fix the error .

I think you need quotes around your {$row['null_field']}, so '{$row['null_field']}'

If you don't have the quotes, you'll occasionally end up with an insert statement that looks like this: insert into table2 (f1, f2) values ('val1',) which is a syntax error.

If that is a numeric field, you will have to do some testing above it, and if there is no value in null_field, explicitly set it to null..

Simple answer: a lot longer than two months. Learning to program competently will take longer than that, no matter what. It took me years to learn to be a competent object-oriented programmer, and I'm good at this stuff.

More detailed answers: it doesn't really matter whether you learn C# or SQL first, as they're very different. I'd probably suggest SQL, as it's easier to learn and more independently useful.

You will have a hard time getting used to the on-the-job realities at home, much as if you were studying plumbing or quantitative finance.

You're going to have a hard time putting all the information together without one or more projects you try to do. You're going to need to have other people to tell you when you're being stupid, when you're being overclever and will pay for it later, and when you're actually getting it.

Try to find an open source project you find vaguely interesting. Study their code. Figure out why they do what they do. Look at the bug list, and try to find something as trivial as possible to fix. Work from there. Learning to contribute is going to teach you things that are useful in the work world, and it will give you something to point at. It will be far easier to get your first job if you have some experience to point to.

1. If you believe that you added a path of native lib to %PATH%, try testing with:

   System.out.println(System.getProperty("java.library.path"))
   

It should show you actually if your dll is on %PATH%

2. Restart the IDE Idea, which appeared to work for me after I setup the env variable by adding it to the %PATH%

In your component i.e angular JS code:

function getData(){
    window.location.href = 'http://localhost:1036/api/Employee/GetExcelData';
}

As simple as that

  private static byte[] getByteArrayFromByteBuffer(ByteBuffer byteBuffer) {
    byte[] bytesArray = new byte[byteBuffer.remaining()];
    byteBuffer.get(bytesArray, 0, bytesArray.length);
    return bytesArray;
}

URIs identify and URLs locate; however, locators are also identifiers, so every URL is also a URI, but there are URIs which are not URLs.

Examples

• Roger Pate

This is my name, which is an identifier. It is like a URI, but cannot be a URL, as it tells you nothing about my location or how to contact me. In this case it also happens to identify at least 5 other people in the USA alone.

• 4914 West Bay Street, Nassau, Bahamas

This is a locator, which is an identifier for that physical location. It is like both a URL and URI (since all URLs are URIs), and also identifies me indirectly as "resident of..". In this case it uniquely identifies me, but that would change if I get a roommate.

I say "like" because these examples do not follow the required syntax.

Popular confusion

From Wikipedia:

In computing, a Uniform Resource Locator (URL) is a subset of the Uniform Resource Identifier (URI) that specifies where an identified resource is available and the mechanism for retrieving it. In popular usage and in many technical documents and verbal discussions it is often incorrectly used as a synonym for URI, ... [emphasis mine]

Because of this common confusion, many products and documentation incorrectly use one term instead of the other, assign their own distinction, or use them synonymously.

URNs

My name, Roger Pate, could be like a URN (Uniform Resource Name), except those are much more regulated and intended to be unique across both space and time.

Because I currently share this name with other people, it's not globally unique and would not be appropriate as a URN. However, even if no other family used this name, I'm named after my paternal grandfather, so it still wouldn't be unique across time. And even if that wasn't the case, the possibility of naming my descendants after me make this unsuitable as a URN.

URNs are different from URLs in this rigid uniqueness constraint, even though they both share the syntax of URIs.

sudo -u postgres createuser -s tom 

this should help you as this will happen if the administrator has not created a PostgreSQL user account for you. It could also be that you were assigned a PostgreSQL user name that is different from your operating system user name, in that case you need to use the -U switch.

Put your query (e.g. db.someCollection.find().pretty()) to a javascript file, let's say query.js. Then run it in your operating system's shell using command:

mongo yourDb < query.js > outputFile

Query result will be in the file named 'outputFile'.

By default Mongo prints out first 20 documents IIRC. If you want more you can define new value to batch size in Mongo shell, e.g.

DBQuery.shellBatchSize = 100.

I'm not Reputable enough to upvote or comment yet, but LukeH's answer was spot on for me.

As AES encryption is the standard to use now, it produces a base64 string (at least all the encrypt/decrypt implementations I've seen). This string has a length in multiples of 4 (string.length % 4 = 0)

The strings I was getting contained + and = on the beginning or end, and when you just concatenate that into a URL's querystring, it will look right (for instance, in an email you generate), but when the the link is followed and the .NET page recieves it and puts it into this.Page.Request.QueryString, those special characters will be gone and your string length will not be in a multiple of 4.

As the are special characters at the FRONT of the string (ex: +), as well as = at the end, you can't just add some = to make up the difference as you are altering the cypher text in a way that doesn't match what was actually in the original querystring.

So, wrapping the cypher text with HttpUtility.URLEncode (not HtmlEncode) transforms the non-alphanumeric characters in a way that ensures .NET parses them back into their original state when it is intepreted into the querystring collection.

The good thing is, we only need to do the URLEncode when generating the querystring for the URL. On the incoming side, it's automatically translated back into the original string value.

Here's some example code

string cryptostring = MyAESEncrypt(MySecretString);
string URL = WebFunctions.ToAbsoluteUrl("~/ResetPassword.aspx?RPC=" + HttpUtility.UrlEncode(cryptostring));

Today at midnight. Easy.

$stamp = mktime(0, 0, 0);

The best one I have used and researched on it is $request->merge([]) (Check My Piece of Code):

public function index(Request $request) {
    not_permissions_redirect(have_premission(2));
    $filters = (!empty($request->all())) ? true : false;
    $request->merge(['type' => 'admin']);
    $users = $this->service->getAllUsers($request->all());
    $roles = $this->roles->getAllAdminRoles();
    return view('users.list', compact(['users', 'roles', 'filters']));
}

Check line # 3 inside the index function.

After valueTuples, what's the use of ExpandoObject class? this 6 lines code with ExpandoObject:

dynamic T = new ExpandoObject();
T.x = 1;
T.y = 2;
T.z = new ExpandoObject();
T.z.a = 3;
T.b= 4;

can be written in one line with tuples:

var T = (x: 1, y: 2, z: (a: 3, b: 4));

besides with tuple syntax you have strong type inference and intlisense support

This is the code to subtract one date from another. This example converts the dates to objects as the getTime() function won't work unless it's an Date object.

    var dat1 = document.getElementById('inputDate').value;
                var date1 = new Date(dat1)//converts string to date object
                alert(date1);
                var dat2 = document.getElementById('inputFinishDate').value;
                var date2 = new Date(dat2)
                alert(date2);

                var oneDay = 24 * 60 * 60 * 1000; // hours*minutes*seconds*milliseconds
                var diffDays = Math.abs((date1.getTime() - date2.getTime()) / (oneDay));
                alert(diffDays);

The capitalization is wrong, and you have an extra argument.

Do this instead:

$('img#thumb').removeAttr('id');

For future reference, there aren't any jQuery methods that begin with a capital letter. They all take the same form as this one, starting with a lower case, and the first letter of each joined "word" is upper case.

If you're using Bash, you don't even have to use grep:

files="*.jpg"
regex="[0-9]+_([a-z]+)_[0-9a-z]*"
for f in $files    # unquoted in order to allow the glob to expand
do
    if [[ $f =~ $regex ]]
    then
        name="${BASH_REMATCH[1]}"
        echo "${name}.jpg"    # concatenate strings
        name="${name}.jpg"    # same thing stored in a variable
    else
        echo "$f doesn't match" >&2 # this could get noisy if there are a lot of non-matching files
    fi
done

It's better to put the regex in a variable. Some patterns won't work if included literally.

This uses =~ which is Bash's regex match operator. The results of the match are saved to an array called $BASH_REMATCH. The first capture group is stored in index 1, the second (if any) in index 2, etc. Index zero is the full match.

You should be aware that without anchors, this regex (and the one using grep) will match any of the following examples and more, which may not be what you're looking for:

123_abc_d4e5
xyz123_abc_d4e5
123_abc_d4e5.xyz
xyz123_abc_d4e5.xyz

To eliminate the second and fourth examples, make your regex like this:

^[0-9]+_([a-z]+)_[0-9a-z]*

which says the string must start with one or more digits. The carat represents the beginning of the string. If you add a dollar sign at the end of the regex, like this:

^[0-9]+_([a-z]+)_[0-9a-z]*$

then the third example will also be eliminated since the dot is not among the characters in the regex and the dollar sign represents the end of the string. Note that the fourth example fails this match as well.

If you have GNU grep (around 2.5 or later, I think, when the \K operator was added):

name=$(echo "$f" | grep -Po '(?i)[0-9]+_\K[a-z]+(?=_[0-9a-z]*)').jpg

The \K operator (variable-length look-behind) causes the preceding pattern to match, but doesn't include the match in the result. The fixed-length equivalent is (?<=) - the pattern would be included before the closing parenthesis. You must use \K if quantifiers may match strings of different lengths (e.g. +, *, {2,4}).

The (?=) operator matches fixed or variable-length patterns and is called "look-ahead". It also does not include the matched string in the result.

In order to make the match case-insensitive, the (?i) operator is used. It affects the patterns that follow it so its position is significant.

The regex might need to be adjusted depending on whether there are other characters in the filename. You'll note that in this case, I show an example of concatenating a string at the same time that the substring is captured.

The PHP code is executed on the server, so your redirect is executed before the browser even sees the JavaScript.

The first way
Needs root

Use kill:

adb shell ps => Will list all running processes on the device and their process ids
adb shell kill <PID> => Instead of <PID> use process id of your application

The second way
In Eclipse open DDMS perspective.
In Devices view you will find all running processes.
Choose the process and click on Stop.

The third way
It will kill only background process of an application.

adb shell am kill [options] <PACKAGE> => Kill all processes associated with (the app's package name). This command kills only processes that are safe to kill and that will not impact the user experience.
Options are:

--user | all | current: Specify user whose processes to kill; all users if not specified.

The fourth way
Needs root

adb shell pm disable <PACKAGE> => Disable the given package or component (written as "package/class").

The fifth way
Note that run-as is only supported for apps that are signed with debug keys.

run-as <package-name> kill <pid>

The sixth way
Introduced in Honeycomb

adb shell am force-stop <PACKAGE> => Force stop everything associated with (the app's package name).

P.S.: I know that the sixth method didn't work for you, but I think that it's important to add this method to the list, so everyone will know it.

You can use IIF (I think from SQL Server 2012)

Prepared statements / parameterized queries are generally sufficient to prevent 1st order injection on that statement^*. If you use un-checked dynamic sql anywhere else in your application you are still vulnerable to 2nd order injection.

2nd order injection means data has been cycled through the database once before being included in a query, and is much harder to pull off. AFAIK, you almost never see real engineered 2nd order attacks, as it is usually easier for attackers to social-engineer their way in, but you sometimes have 2nd order bugs crop up because of extra benign ' characters or similar.

You can accomplish a 2nd order injection attack when you can cause a value to be stored in a database that is later used as a literal in a query. As an example, let's say you enter the following information as your new username when creating an account on a web site (assuming MySQL DB for this question):

' + (SELECT UserName + '_' + Password FROM Users LIMIT 1) + '

If there are no other restrictions on the username, a prepared statement would still make sure that the above embedded query doesn't execute at the time of insert, and store the value correctly in the database. However, imagine that later the application retrieves your username from the database, and uses string concatenation to include that value a new query. You might get to see someone else's password. Since the first few names in users table tend to be admins, you may have also just given away the farm. (Also note: this is one more reason not to store passwords in plain text!)

We see, then, that prepared statements are enough for a single query, but by themselves they are not sufficient to protect against sql injection attacks throughout an entire application, because they lack a mechanism to enforce all access to a database within an application uses safe code. However, used as part of good application design — which may include practices such as code review or static analysis, or use of an ORM, data layer, or service layer that limits dynamic sql — prepared statements are the primary tool for solving the Sql Injection problem. If you follow good application design principles, such that your data access is separated from the rest of your program, it becomes easy to enforce or audit that every query correctly uses parameterization. In this case, sql injection (both first and second order) is completely prevented.

_{^*It turns out that MySql/PHP are (okay, were) just dumb about handling parameters when wide characters are involved, and there is still a rare case outlined in the other highly-voted answer here that can allow injection to slip through a parameterized query.}

Being a geezer programmer, many of my school programming projects used text menu driven interactions. Virtually all used something like the following logic for the main procedure:

do
    display options
    get choice
    perform action appropriate to choice
while choice is something other than exit

Since school days, I have found that I use the while loop more frequently.

public class SortingArray {
public static void main(String[] args) {

int[] a={3,7,9,5,1,4,0,2,8,6};
int temp=0;

boolean isSwapped=true;


System.out.println(" before sorting the array: ");

for(int i=0;i<a.length;i++)
{
    System.out.print(a[i]);
}
System.out.println("");

do
{

isSwapped=false;

for(int i=0;i<a.length-1;i++)

{

    if(a[i]>a[i+1])

    {

        temp=a[i];

        a[i]=a[i+1];

        a[i+1]=temp;

    }



}


}while(isSwapped);


System.out.println("after sorting the array: ");

    for(int array:a)

    {

        System.out.print(array);


    }
  }
}

How can I decrypt MySQL passwords

You can't really because they are hashed and not encrypted.

Here's the essence of the PASSWORD function that current MySQL uses. You can execute it from the sql terminal:

mysql> SELECT SHA1(UNHEX(SHA1("password")));

+------------------------------------------+
| SHA1(UNHEX(SHA1("password")))            |
+------------------------------------------+
| 2470C0C06DEE42FD1618BB99005ADCA2EC9D1E19 |
+------------------------------------------+
1 row in set (0.00 sec)

How can I change or retrieve these?

If you are having trouble logging in on a debian or ubuntu system, first try this (thanks to tohuwawohu at https://askubuntu.com/questions/120718/cant-log-to-mysql):

$ sudo cat /etc/mysql/debian.conf | grep -i password
...
password: QWERTY12345...

Then, log in with the debian maintenance user:

$ mysql -u debian-sys-maint -p
password:

Finally, change the user's password:

mysql> UPDATE mysql.user SET Password=PASSWORD('new password') WHERE User='root';
mysql> FLUSH PRIVILEGES;
mysql> quit;

When I look in the PHPmyAdmin the passwords are encrypted

Related, if you need to dump the user database for the relevant information, try:

mysql> SELECT User,Host,Password FROM mysql.user;
+------------------+-----------+----------------------+
| User             | Host      | Password             |
+------------------+-----------+----------------------+
| root             | localhost | *0123456789ABCDEF... |
| root             | 127.0.0.1 | *0123456789ABCDEF... |
| root             | ::1       | *0123456789ABCDEF... |

And yes, those passwords are NOT salted. So an attacker can prebuild the tables and apply them to all MySQL installations. In addition, the adversary can learn which users have the same passwords.

Needles to say, the folks at mySQL are not following best practices. John Steven did an excellent paper on Password Storage Best Practice at OWASP's Password Storage Cheat Sheet. In fairness to the MySQL folks, they may be doing it because of pain points in the architecture, design or implementation (I simply don't know).

If you use the PASSWORD and UPDATE commands and the change does not work, then see http://dev.mysql.com/doc/refman/5.0/en/resetting-permissions.html. Even though the page is named "resetting permissions", its really about how to change a password. (Its befuddling the MySQL password change procedure is so broken that you have to jump through the hoops, but it is what it is).

Try adding a Reference to System.Configuration, you get some of the configuration namespace by referencing the System namespace, adding the reference to System.Configuration should allow you to access ConfigurationManager.

It should be possible to create custom java agent that overrides default HostnameVerifier:

import javax.net.ssl.*;
import java.lang.instrument.Instrumentation;

public class LenientHostnameVerifierAgent {
    public static void premain(String args, Instrumentation inst) {
        HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
            public boolean verify(String s, SSLSession sslSession) {
                return true;
            }
        });
    }
}

Then just add -javaagent:LenientHostnameVerifierAgent.jar to program's java startup arguments.

I encountered this issue while importing some of the files from the Add Health data into R (see: http://www.icpsr.umich.edu/icpsrweb/ICPSR/studies/21600?archive=ICPSR&q=21600 ) For example, the following command to read the DS12 data file in tab separated .tsv format will generate the following error:

ds12 <- read.table("21600-0012-Data.tsv", sep="\t", comment.char="", 
quote = "\"", header=TRUE)

Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, 
na.strings,  : line 2390 did not have 1851 elements

It appears there is a slight formatting issue with some of the files that causes R to reject the file. At least part of the issue appears to be the occasional use of double quotes instead of an apostrophe that causes an uneven number of double quote characters in a line.

After fiddling, I've identified three possible solutions:

1. Open the file in a text editor and search/replace all instances of a quote character " with nothing. In other words, delete all double quotes. For this tab-delimited data, this meant only that some verbatim excerpts of comments from subjects were no longer in quotes which was a non-issue for my data analysis.

2. With data stored on ICPSR (see link above) or other archives another solution is to download the data in a new format. A good option in this case is to download the Stata version of the DS12 and then open it using the read.dta command as follows:

   library(foreign)
   ds12 <- read.dta("21600-0012-Data.dta")
   

3. A related solution/hack is to open the .tsv file in Excel and re-save it as a tab separated text file. This seems to clean up whatever formatting issue makes R unhappy.

None of these are ideal in that they don't quite solve the problem in R with the original .tsv file but data wrangling often requires the use of multiple programs and formats.

It seems that if you know the type of elements in the array you can also use that to your advantage with sizeof.

int numList[] = { 0, 1, 2, 3, 4 };

cout << sizeof(numList) / sizeof(int);

// => 5

Lets assume we have the string variables $string, $start, and $limit we can borrow 3 or 4 functions from PHP to achieve this. They are:

• script_tags() PHP function to remove the unnecessary HTML and PHP tags (if there are any). This wont be necessary, if there are no HTML or PHP tags.
• explode() to split the $string into an array
• array_splice() to specify the number of words and where it'll start from. It'll be controlled by vallues assigned to our $start and $limit variables.

• and finally, implode() to join the array elements into your truncated string..

  function truncateString($string, $start, $limit){
      $stripped_string =strip_tags($string); // if there are HTML or PHP tags
      $string_array =explode(' ',$stripped_string);
      $truncated_array = array_splice($string_array,$start,$limit);
      $truncated_string=implode(' ',$truncated_array);
  
      return $truncated_string;
  }
  

It's that simple..

I hope this was helpful.

The currently-accepted answer to this question is wrong. C11 6.9.2/2:

If a translation unit contains one or more tentative definitions for an identifier, and the translation unit contains no external definition for that identifier, then the behavior is exactly as if the translation unit contains a file scope declaration of that identifier, with the composite type as of the end of the translation unit, with an initializer equal to 0.

So the original code in the question behaves as if file1.c and file2.c each contained the line int i = 0; at the end, which causes undefined behaviour due to multiple external definitions (6.9/5).

Since this is a Semantic rule and not a Constraint, no diagnostic is required.

Here are two more questions about the same code with correct answers:

• Tentative definitions in C and linking
• How do I use extern to share variables between source files?

If you don't want to change your default settings, and you only want to change the width of the current notebook you're working on, you can enter the following into a cell:

from IPython.core.display import display, HTML
display(HTML("<style>.container { width:100% !important; }</style>"))

I am using 11.2 and received timeouts.

I resolved by using the version of jsoup below.

    <dependency>
        <groupId>org.jsoup</groupId>
        <artifactId>jsoup</artifactId>
        <version>1.7.2</version>
        <scope>compile</scope>
    </dependency>

For me, this code worked:

/Applications/Postgres.app/Contents/Versions/9.4/bin/createuser -s postgres

it came from here: http://talk.growstuff.org/t/fatal-role-postgres-does-not-exist/216/4

It wasn't obvious to me that although you can accept a Collection as a request param, but on the consumer side you still have to pass in the collection items as comma separated values.

For example if the server side api looks like this:

@PostMapping("/post-topics")
public void handleSubscriptions(@RequestParam("topics") Collection<String> topicStrings) {

    topicStrings.forEach(topic -> System.out.println(topic));
}

Directly passing in a collection to the RestTemplate as a RequestParam like below will result in data corruption

public void subscribeToTopics() {

    List<String> topics = Arrays.asList("first-topic", "second-topic", "third-topic");

    RestTemplate restTemplate = new RestTemplate();
    restTemplate.postForEntity(
            "http://localhost:8088/post-topics?topics={topics}",
            null,
            ResponseEntity.class,
            topics);
}

Instead you can use

public void subscribeToTopics() {

    List<String> topicStrings = Arrays.asList("first-topic", "second-topic", "third-topic");
    String topics = String.join(",",topicStrings);

    RestTemplate restTemplate = new RestTemplate();
    restTemplate.postForEntity(
            "http://localhost:8088/post-topics?topics={topics}",
            null,
            ResponseEntity.class,
            topics);
}

The complete example can be found here, hope it saves someone the headache :)

here are some code examples taken from the web and from answers to this question.

For Each Method, I have modified the original code so each use the same table and column: NumbersTest and Number, with 10,000 rows or as close to that as possible. Also, I have provided links to the place of origin.

After looking at all these methods, I really like Method 7, which was the fastest and the code is fairly simple too.

setting Cellpadding and cellspacing to 0 will remove the unnecessary space between rows and columns...

You can create a list of lists

   public class MultiDimList: List<List<string>> {  }

or a Dictionary of key-accessible Lists

   public class MultiDimDictList: Dictionary<string, List<int>>  { }
   MultiDimDictList myDicList = new MultiDimDictList ();
   myDicList.Add("ages", new List<int>()); 
   myDicList.Add("Salaries", new List<int>()); 
   myDicList.Add("AccountIds", new List<int>()); 

Generic versions, to implement suggestion in comment from @user420667

  public class MultiDimList<T>: List<List<T>> {  }

and for the dictionary,

   public class MultiDimDictList<K, T>: Dictionary<K, List<T>>  { }

  // to use it, in client code
   var myDicList = new MultiDimDictList<string, int> ();
   myDicList.Add("ages", new List<T>()); 
   myDicList["ages"].Add(23);
   myDicList["ages"].Add(32);
   myDicList["ages"].Add(18);

   myDicList.Add("salaries", new List<T>());
   myDicList["salaries"].Add(80000);
   myDicList["salaries"].Add(100000);

   myDicList.Add("accountIds", new List<T>()); 
   myDicList["accountIds"].Add(321123);
   myDicList["accountIds"].Add(342653);

or, even better, ...

   public class MultiDimDictList<K, T>: Dictionary<K, List<T>>  
   {
       public void Add(K key, T addObject)
       {
           if(!ContainsKey(key)) Add(key, new List<T>());
           if (!base[key].Contains(addObject)) base[key].Add(addObject);
       }           
   }


  // and to use it, in client code
    var myDicList = new MultiDimDictList<string, int> ();
    myDicList.Add("ages", 23);
    myDicList.Add("ages", 32);
    myDicList.Add("ages", 18);
    myDicList.Add("salaries", 80000);
    myDicList.Add("salaries", 110000);
    myDicList.Add("accountIds", 321123);
    myDicList.Add("accountIds", 342653);

EDIT: to include an Add() method for nested instance:

public class NestedMultiDimDictList<K, K2, T>: 
           MultiDimDictList<K, MultiDimDictList<K2, T>>: 
{
       public void Add(K key, K2 key2, T addObject)
       {
           if(!ContainsKey(key)) Add(key, 
                  new MultiDimDictList<K2, T>());
           if (!base[key].Contains(key2)) 
               base[key].Add(key2, addObject);
       }    
}

You can use jspdf to capture a canvas into an image or pdf like this:

var imgData = canvas.toDataURL('image/png');              
var doc = new jsPDF('p', 'mm');
doc.addImage(imgData, 'PNG', 10, 10);
doc.save('sample-file.pdf');

Just use the KeepAlive like @toster-cx says and then use the Socket Connected status to check if the Socket is still connected. Set your receive timeout at the same timeout of the keepalive. If you have more questions i am always happy to help!

I think that the usage of @Html.LabelForModel() should be explained in more detail.

The LabelForModel Method returns an HTML label element and the property name of the property that is represented by the model.

You could refer to the following code:

Code in model:

using System.ComponentModel;

[DisplayName("MyModel")]
public class MyModel
{
    [DisplayName("A property")]
    public string Test { get; set; }
}

Code in view:

@Html.LabelForModel()
<div class="form-group">

    @Html.LabelFor(model => model.Test, new { @class = "control-label col-md-2" })

    <div class="col-md-10">
        @Html.EditorFor(model => model.Test)
        @Html.ValidationMessageFor(model => model.Test)
    </div>
</div>

As the other answers have described, lit and typedLit are how to add constant columns to DataFrames. lit is an important Spark function that you will use frequently, but not for adding constant columns to DataFrames.

You'll commonly be using lit to create org.apache.spark.sql.Column objects because that's the column type required by most of the org.apache.spark.sql.functions.

Suppose you have a DataFrame with a some_date DateType column and would like to add a column with the days between December 31, 2020 and some_date.

Here's your DataFrame:

+----------+
| some_date|
+----------+
|2020-09-23|
|2020-01-05|
|2020-04-12|
+----------+

Here's how to calculate the days till the year end:

val diff = datediff(lit(Date.valueOf("2020-12-31")), col("some_date"))
df
  .withColumn("days_till_yearend", diff)
  .show()

+----------+-----------------+
| some_date|days_till_yearend|
+----------+-----------------+
|2020-09-23|               99|
|2020-01-05|              361|
|2020-04-12|              263|
+----------+-----------------+

You could also use lit to create a year_end column and compute the days_till_yearend like so:

import java.sql.Date

df
  .withColumn("yearend", lit(Date.valueOf("2020-12-31")))
  .withColumn("days_till_yearend", datediff(col("yearend"), col("some_date")))
  .show()

+----------+----------+-----------------+
| some_date|   yearend|days_till_yearend|
+----------+----------+-----------------+
|2020-09-23|2020-12-31|               99|
|2020-01-05|2020-12-31|              361|
|2020-04-12|2020-12-31|              263|
+----------+----------+-----------------+

Most of the time, you don't need to use lit to append a constant column to a DataFrame. You just need to use lit to convert a Scala type to a org.apache.spark.sql.Column object because that's what's required by the function.

See the datediff function signature:

As you can see, datediff requires two Column arguments.

If you want recursive to include subprojects, you can always write it yourself:

Paste into the top-level build.gradle:

task allDeps << {
    println "All Dependencies:"
    allprojects.each { p ->
        println()
        println " $p.name ".center( 60, '*' )
        println()
        p.configurations.all.findAll { !it.allDependencies.empty }.each { c ->
            println " ${c.name} ".center( 60, '-' )
            c.allDependencies.each { dep ->
                println "$dep.group:$dep.name:$dep.version"
            }
            println "-" * 60
        }
    }
}

Run with:

gradle allDeps

You use std::find from <algorithm>, which works equally well for std::list and std::vector. std::vector does not have its own search/find function.

#include <list>
#include <algorithm>

int main()
{
    std::list<int> ilist;
    ilist.push_back(1);
    ilist.push_back(2);
    ilist.push_back(3);

    std::list<int>::iterator findIter = std::find(ilist.begin(), ilist.end(), 1);
}

Note that this works for built-in types like int as well as standard library types like std::string by default because they have operator== provided for them. If you are using using std::find on a container of a user-defined type, you should overload operator== to allow std::find to work properly: EqualityComparable concept

I landed up on this page when searching for a solution for “Could not open input file” error. Here's my 2 cents for this error.

I faced this same error while because I was using parameters in my php file path like this:

/usr/bin/php -q /home/**/public_html/cron/job.php?id=1234

But I found out that this is not the proper way to do it. The proper way of sending parameters is like this:

/usr/bin/php -q /home/**/public_html/cron/job.php id=1234

Just replace the "?" with a space " ".

Use anchor links and the scroll-behavior property (MDN reference) for the scrolling container:

scroll-behavior: smooth;

Browser support: Firefox 36+, Chrome 61+ (therefore also Edge 79+) and Opera 48+.

Intenet Explorer, non-Chromium Edge and (so far) Safari do not support scroll-behavior and simply "jump" to the link target.

Example usage:

<head>
  <style type="text/css">
    html {
      scroll-behavior: smooth;
    }
  </style>
</head>
<body id="body">
  <a href="#foo">Go to foo!</a>

  <!-- Some content -->

  <div id="foo">That's foo.</div>
  <a href="#body">Back to top</a>
</body>

Here's a Fiddle.

And here's also a Fiddle with both horizontal and vertical scrolling.

When you print it with this print 'I\nwould\nexpect\nmultiple\nlines' you would get:

I
would
expect
multiple
lines

The \n is a new line character specially used for marking END-OF-TEXT. It signifies the end of the line or text. This characteristics is shared by many languages like C, C++ etc.

Try

.img{
   width:100vw; /* Matches to the Viewport Width */
   height:auto;
   max-width:100% !important;
}

Only works with display block and inline block, this has no effect on flex items as I've just spent ages trying to find out.

Easy way of doing it would be:

<input type="file" accept=".gif,.jpg,.jpeg,.png,.doc,.docx">

Works with all browsers, except IE9. I haven't tested it in IE10+.

typeperf gives me issues when it randomly doesn't work on some computers (Error: No valid counters.) or if the account has insufficient rights. Otherwise, here is a way to extract just the value from its output. It still needs rounding though:

@for /f "delims=, tokens=2" %p in ('typeperf "\Processor(_Total)\% Processor Time" -sc 3 ^| find ":"') do @echo %~p%

Powershell has two cmdlets to get the percent utilization for all CPUs: Get-Counter (preferred) or Get-WmiObject:

Powershell "Get-Counter '\Processor(*)\% Processor Time' | Select -Expand Countersamples | Select InstanceName, CookedValue"

Or,

Powershell "Get-WmiObject Win32_PerfFormattedData_PerfOS_Processor | Select Name, PercentProcessorTime"

To get the overall CPU load with formatted output exactly like the question:

Powershell "[string][int](Get-Counter '\Processor(*)\% Processor Time').Countersamples[0].CookedValue + '%'"

Or,

 Powershell "gwmi Win32_PerfFormattedData_PerfOS_Processor | Select -First 1 | %{'{0}%' -f $_.PercentProcessorTime}"

As a follow on, you could select "all nodes with a particular attribute" like this:

//*[@id='4']

Two important notes:

1. You need to call layoutIfNeeded within the animation block. Apple actually recommends you call it once before the animation block to ensure that all pending layout operations have been completed

2. You need to call it specifically on the parent view (e.g. self.view), not the child view that has the constraints attached to it. Doing so will update all constrained views, including animating other views that might be constrained to the view that you changed the constraint of (e.g. View B is attached to the bottom of View A and you just changed View A's top offset and you want View B to animate with it)

Try this:

Objective-C

- (void)moveBannerOffScreen {
    [self.view layoutIfNeeded];

    [UIView animateWithDuration:5
        animations:^{
            self._addBannerDistanceFromBottomConstraint.constant = -32;
            [self.view layoutIfNeeded]; // Called on parent view
        }];
    bannerIsVisible = FALSE;
}

- (void)moveBannerOnScreen { 
    [self.view layoutIfNeeded];

    [UIView animateWithDuration:5
        animations:^{
            self._addBannerDistanceFromBottomConstraint.constant = 0;
            [self.view layoutIfNeeded]; // Called on parent view
        }];
    bannerIsVisible = TRUE;
}

Swift 3

UIView.animate(withDuration: 5) {
    self._addBannerDistanceFromBottomConstraint.constant = 0
    self.view.layoutIfNeeded()
}

The filename should be a string. In other names it should be within quotes.

f = open("D\\python\\HW\\2_1 - Copy.cp","r")
lines = f.readlines()
for i in lines:
    thisline = i.split(" ");

You can also open the file using with

with open("D\\python\\HW\\2_1 - Copy.cp","r") as f:
    lines = f.readlines()
    for i in lines:
        thisline = i.split(" ");

There is no need to add the semicolon(;) in python. It's ugly.

I came across the situation where I met a condition that broke the loop, however the code after the .each() function still executed. I then set a flag to "true" with an immediate check for the flag after the .each() function to ensure the code that followed was not executed.

$('.groupName').each(function() {
    if($(this).text() == groupname){
        alert('This group already exists');
        breakOut = true;
        return false;
    }
});
if(breakOut) {
    breakOut = false;
    return false;
} 

Assuming your string is s:

'$' in s        # found
'$' not in s    # not found

# original answer given, but less Pythonic than the above...
s.find('$')==-1 # not found
s.find('$')!=-1 # found

And so on for other characters.

... or

pattern = re.compile(r'\d\$,')
if pattern.findall(s):
    print('Found')
else
    print('Not found')

... or

chars = set('0123456789$,')
if any((c in chars) for c in s):
    print('Found')
else:
    print('Not Found')

[Edit: added the '$' in s answers]

I'm Using Windows 8.1 and I use this command

c:\wamp\bin\mysql\mysql5.6.12\bin\mysql.exe

instead of

 c:\wamp\bin\mysql\mysql5.6.12\bin\mysqld

and it works fine..

With CMake, it's generally recommended to do an "out of source" build. Create your CMakeLists.txt in the root of your project. Then from the root of your project:

mkdir Release
cd Release
cmake -DCMAKE_BUILD_TYPE=Release ..
make

And for Debug (again from the root of your project):

mkdir Debug
cd Debug
cmake -DCMAKE_BUILD_TYPE=Debug ..
make

Release / Debug will add the appropriate flags for your compiler. There are also RelWithDebInfo and MinSizeRel build configurations.

You can modify/add to the flags by specifying a toolchain file in which you can add CMAKE_<LANG>_FLAGS_<CONFIG>_INIT variables, e.g.:

set(CMAKE_CXX_FLAGS_DEBUG_INIT "-Wall")
set(CMAKE_CXX_FLAGS_RELEASE_INIT "-Wall")

See CMAKE_BUILD_TYPE for more details.

As for your third question, I'm not sure what you are asking exactly. CMake should automatically detect and use the compiler appropriate for your different source files.

the provided solutions seem a little complex? this might help:

https://msdn.microsoft.com/en-us/library/ms174420.aspx

select
   mystuff,
   DATEPART ( year, MyDateColumn ) as yearnr,
   DATEPART ( week, MyDateColumn ) as weeknr
from mytable
group by ...etc

You have to do this on the change event of the input type file this way:

$('#select_file').click(function() {
    $('#image_file').show();
    $('.btn').prop('disabled', false);
    $('#image_file').change(function() {
        var filename = $('#image_file').val();
        $('#select_file').html(filename);
    });
});?

Since the only noise terminals tend to make is the bell and if you want it off everywhere, the very simplest way to do it for bash on Windows:

1. Mash backspace a bunch at the prompt
2. Right click sound icon and choose Open Volume Mixer
3. Lower volume on Console Window Host to zero

If you're trying to add typings to a destructured object literal, for example in arguments to a function, the syntax is:

function foo({ bar, baz }: { bar: boolean, baz: string }) {
  // ...
}

foo({ bar: true, baz: 'lorem ipsum' });

This worked for me:

static void ClearLine(){
    Console.SetCursorPosition(0, Console.CursorTop);
    Console.Write(new string(' ', Console.WindowWidth)); 
    Console.SetCursorPosition(0, Console.CursorTop - 1);
}

It seem that w3c switched it to font/woff2

I see there is some discussion about the proper mime type. In the link we read:

This document defines a top-level MIME type "font" ...

... the officially defined IANA subtypes such as "application/font-woff" ...

The members of the W3C WebFonts WG believe the use of "application" top-level type is not ideal.

and later

6.5. WOFF 2.0

    Type name:

        font
    Subtype name:

        woff2

So proposition from W3C differs from IANA.

We can see that it also differs from woff type: http://dev.w3.org/webfonts/WOFF/spec/#IMT where we read:

Type name:

    application
Subtype name:

    font-woff

which is

application/font-woff

Viewport units for CSS

1vw = 1% of viewport width
1vh = 1% of viewport height

This way, you don't have to write many different media queries or javascript.

If you prefer JS

window.innerWidth;
window.innerHeight;

If you have a file called scaffolds.css.scss, then there's a chance that's overriding all the custom things you're doing in the other files. I commented out that file and suddenly everything worked. If there isn't anything important in that file, you might as well just delete it!

You might check Select2 plugin:

http://ivaynberg.github.io/select2/

Select2 is a jQuery based replacement for select boxes. It supports searching, remote data sets, and infinite scrolling of results.

It's quite popular and very maintainable. It should cover most of your needs if not all.

Long story short, node draws from V8, which is internally single-threaded. There are ways to work around the constraints for CPU-intensive tasks.

At one point (0.7) the authors tried to introduce isolates as a way of implementing multiple threads of computation, but were ultimately removed: https://groups.google.com/forum/#!msg/nodejs/zLzuo292hX0/F7gqfUiKi2sJ

function getURLParameter(name) {
  return decodeURIComponent((new RegExp('[?|&]' + name + '=' + '([^&;]+?)(&|#|;|$)').exec(location.search) || [null, ''])[1].replace(/\+/g, '%20')) || null;
}

So you can use:

myvar = getURLParameter('myvar');

Make sure you have project_id in the fillable property of your Comment model.

I had the same issue, And this was the reason.

What about this: ^[1-9][0-9]*$

My synopsis of rfc2397 is:

Once you've got your base64 encoded image data put it inside the <Image></Image> tags prefixed with "data:{mimetype};base64," this is similar to the prefixing done in the parenthesis of url() definition in CSS or in the quoted value of the src attribute of the img tag in [X]HTML. You can test the data url in firefox by putting the data:image/... line into the URL field and pressing enter, it should show your image.

For actually encoding I think we need to go over all your options, not just PHP, because there's so many ways to base64 encode something.

1. Use the base64 command line tool. It's part of the GNU coreutils (v6+) and pretty much default in any Cygwin, Linux, GnuWin32 install, but not the BSDs I tried. Issue: $ base64 imagefile.ico > imagefile.base64.txt
2. Use a tool that features the option to convert to base64, like Notepad++ which has the feature under plugins->MIME tools->base64 Encode
3. Email yourself the file and view the raw email contents, copy and paste.
4. Use a web form.

A note on mime-types: I would prefer you use one of image/png image/jpeg or image/gif as I can't find the popular image/x-icon. Should that be image/vnd.microsoft.icon? Also the other formats are much shorter.

compare 265 bytes vs 1150 bytes:

You can do the following

1. Click on extensions
2. Type Reload
3. Then install

It will add a reload button on your right hand at the bottom of the vs code.

Use the $(( )) arithmetic expansion.

num=$(( $num + $metab ))

See Chapter 13. Arithmetic Expansion for more information.

I don't know if you can change the size at runtime but you can allocate the size at runtime. Try using this code:

class MyClass {
    void myFunction () {
        Scanner s = new Scanner (System.in);
        int myArray [];
        int x;

        System.out.print ("Enter the size of the array: ");
        x = s.nextInt();

        myArray = new int[x];
    }
}

this assigns your array size to be the one entered at run time into x.

You can use these commands:

npm cache clean
npm update -g [package....]

If you are upgrading from a previous version of node, then you will want to update all existing global packages. You can also specify the package name to be updated.

public static String readClob(Clob clob) throws SQLException, IOException {
    StringBuilder sb = new StringBuilder((int) clob.length());
    Reader r = clob.getCharacterStream();
    char[] cbuf = new char[2048];
    int n;
    while ((n = r.read(cbuf, 0, cbuf.length)) != -1) {
        sb.append(cbuf, 0, n);
    }
    return sb.toString();
}

The above approach is also very efficient.

Serialization is the process of saving an object in a storage medium (such as a file, or a memory buffer) or to transmit it over a network connection in binary form. The serialized objects are JVM independent and can be re-serialized by any JVM. In this case the "in memory" java objects state are converted into a byte stream. This type of the file can not be understood by the user. It is a special types of object i.e. reused by the JVM (Java Virtual Machine). This process of serializing an object is also called deflating or marshalling an object.

The object to be serialized must implement java.io.Serializable Interface. Default serialization mechanism for an object writes the class of the object, the class signature, and the values of all non-transient and non-static fields.

class ObjectOutputStream extends java.io.OutputStream implements ObjectOutput,

ObjectOutput interface extends the DataOutput interface and adds methods for serializing objects and writing bytes to the file. The ObjectOutputStream extends java.io.OutputStream and implements ObjectOutput interface. It serializes objects, arrays, and other values to a stream. Thus the constructor of ObjectOutputStream is written as:

ObjectOutput ObjOut = new ObjectOutputStream(new FileOutputStream(f));

Above code has been used to create the instance of the ObjectOutput class with the ObjectOutputStream( ) constructor which takes the instance of the FileOuputStream as a parameter.

The ObjectOutput interface is used by implementing the ObjectOutputStream class. The ObjectOutputStream is constructed to serialize the object.

Deserializing an Object in java

The opposite operation of the serialization is called deserialization i.e. to extract the data from a series of bytes is s known as deserialization which is also called inflating or unmarshalling.

ObjectInputStream extends java.io.InputStream and implements ObjectInput interface. It deserializes objects, arrays, and other values from an input stream. Thus the constructor of ObjectInputStream is written as:

ObjectInputStream obj = new ObjectInputStream(new FileInputStream(f));

Above code of the program creates the instance of the ObjectInputStream class to deserialize that file which had been serialized by the ObjectInputStream class. The above code creates the instance using the instance of the FileInputStream class which holds the specified file object which has to be deserialized because the ObjectInputStream() constructor needs the input stream.

Something like this should work unless I'm missing the point:

import json
import urllib2
json.load(urllib2.urlopen("url"))

Simply using "target=_blank" will respect the user/browser preference of whether to use a tab or a new window, which in most cases is "doing the right thing".

• IE9+ Default: Tab : Preference: "Always open pop-ups in a new tab"
• Chrome Default: Tab. Hidden preference:
• Firefox: Default: Tab https://support.mozilla.org/en-US/kb/tab-preferences-and-settings
• Safari: Default: Tab

If you specify the dimensions of the new window, some browsers will use this as an indicator that a certain size is needed, in which case a new window will always be used. Stack overflow code example Stack Overflow

String s1=""; // empty string assigned to s1 , s1 has length 0, it holds a value of no length string

String s2=null; // absolutely nothing, it holds no value, you are not assigning any value to s2

so null is not the same as empty.

hope that helps!!!

Maybe you want unpack elements of array, I don't know if I got it, but below a example:

def my_func(*args):
    for a in args:
        print a

my_func(*[1,2,3,4])
my_list = ['a','b','c']
my_func(*my_list)

Use this:

TextView txt = (TextView) findViewById(R.id.Textview1);
txt.setPaintFlags(txt.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);

Class that will call the methods:

namespace myNamespace
{
    public class myClass
    {
        public static void voidMethodWithoutParameters()
        {
            // code here
        }
        public static string stringReturnMethodWithParameters(string param1, string param2)
        {
            // code here
            return "output";
        }
    }
}

Calling myClass static methods using Reflection:

var myClassType = Assembly.GetExecutingAssembly().GetType(GetType().Namespace + ".myClass");
                    
// calling my void Method that has no parameters.
myClassType.GetMethod("voidMethodWithoutParameters", BindingFlags.Public | BindingFlags.Static).Invoke(null, null);

// calling my string returning Method & passing to it two string parameters.
Object methodOutput = myClassType.GetMethod("stringReturnMethodWithParameters", BindingFlags.Public | BindingFlags.Static).Invoke(null, new object[] { "value1", "value1" });
Console.WriteLine(methodOutput.ToString());

Note: I don't need to instantiate an object of myClass to use it's methods, as the methods I'm using are static.

Great resources:

• How C# Reflection Works
• MethodBase.Invoke Method

I understand that the answer is given but I wrote a simple example to make it easy to understand for beginners like me:

var x = { println("x"); 15 }
lazy val y = { println("y"); x + 1 }
println("-----")
x = 17
println("y is: " + y)

Output of above code is:

x
-----
y
y is: 18

As it can be seen, x is printed when it's initialized, but y is not printed when it's initialized in same way (I have taken x as var intentionally here - to explain when y gets initialized). Next when y is called, it's initialized as well as value of last 'x' is taken into consideration but not the old one.

Hope this helps.

Have a look at the WebRequestHandler Class and its ServerCertificateValidationCallback Property:

using (var handler = new WebRequestHandler())
{
    handler.ServerCertificateValidationCallback = ...

    using (var client = new HttpClient(handler))
    {
        ...
    }
}

You can easily use the MODE argument:

MySQL :: MySQL 5.5 Reference Manual :: 12.7 Date and Time Functions

If the mode argument is omitted, the value of the default_week_format system variable is used:

MySQL :: MySQL 5.1 Reference Manual :: 5.1.4 Server System Variables

Angular has a built-in filter for showing JSON

<pre>{{data | json}}</pre>

Note the use of the pre-tag to conserve whitespace and linebreaks

Demo:

angular.module('app', [])_x000D_
  .controller('Ctrl', ['$scope',_x000D_
    function($scope) {_x000D_
_x000D_
      $scope.data = {_x000D_
        a: 1,_x000D_
        b: 2,_x000D_
        c: {_x000D_
          d: "3"_x000D_
        },_x000D_
      };_x000D_
_x000D_
    }_x000D_
  ]);

<!DOCTYPE html>_x000D_
<html ng-app="app">_x000D_
_x000D_
  <head>_x000D_
    <script data-require="[email protected]" data-semver="1.2.15" src="//code.angularjs.org/1.2.15/angular.js"></script>_x000D_

  <body ng-controller="Ctrl">_x000D_
    <pre>{{data | json}}</pre>_x000D_
  </body>_x000D_
_x000D_
</html>

There's also an angular.toJson method, but I haven't played around with that (Docs)

As RocketDonkey suggested, your module itself needs to have some docstrings.

For example, in myModule/__init__.py:

"""
The mod module
"""

You'd also want to generate documentation for each file in myModule/*.py using

pydoc myModule.thefilename

to make sure the generated files match the ones that are referenced from the main module documentation file.

I happen to miss spaces in my query and this error comes.

Ex: $sql= "SELECT * FROM";
$sql .= "table1";

Though the example might look simple, when coding complex queries, the probability for this error is high. I was missing space before word "table1".

For those who expect JSON and still getting the same error, make sure that you parse your data:

$scope.customers = JSON.parse(data)

Just wishing to avoid the console error, I solved this using a similar approach to Artur's earlier answer, following these steps:

1. Downloaded the YouTube Iframe API (from https://www.youtube.com/iframe_api) to a local yt-api.js file.
2. Removed the code which inserted the www-widgetapi.js script.
3. Downloaded the www-widgetapi.js script (from https://s.ytimg.com/yts/jsbin/www-widgetapi-vfl7VfO1r/www-widgetapi.js) to a local www-widgetapi.js file.
4. Replaced the targetOrigin argument in the postMessage call which was causing the error in the console, with a "*" (indicating no preference - see https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage).
5. Appended the modified www-widgetapi.js script to the end of the yt-api.js script.

This is not the greatest solution (patched local script to maintain, losing control of where messages are sent) but it solved my issue.

Please see the security warning about removing the targetOrigin URI stated here before using this solution - https://developer.mozilla.org/en-US/docs/Web/API/Window/postMessage

Patched yt-api.js example

If you're on the New Google Sheets, this is all you need to do, according to the docs:

change your recalculation setting to "On change and every minute" in your spreadsheet at File > Spreadsheet settings.

This will make the entire sheet update itself every minute, on the server side, regardless of whether you have the spreadsheet up in your browser or not.

If you're on the old Google Sheets, you'll want to add a cell with this formula to achieve the same functionality:

=GoogleClock()

EDIT to include old and new Google Sheets and change to =GoogleClock().

Just like any other environment variable, with SET:

SET PATH=%PATH%;c:\whatever\else

If you want to have a little safety check built in first, check to see if the new path exists first:

IF EXIST c:\whatever\else SET PATH=%PATH%;c:\whatever\else

If you want that to be local to that batch file, use setlocal:

setlocal
set PATH=...
set OTHERTHING=...

@REM Rest of your script

Read the docs carefully for setlocal/endlocal , and have a look at the other references on that site - Functions is pretty interesting too and the syntax is tricky.

The Syntax page should get you started with the basics.

I think LayeredPane is your best bet here. You would need a third panel though to contain A and B. This third panel would be the layeredPane and then panel A and B could still have a nice LayoutManagers. All you would have to do is center B over A and there is quite a lot of examples in the Swing trail on how to do this. Tutorial for positioning without a LayoutManager.

public class Main {
    private JFrame frame = new JFrame();
    private JLayeredPane lpane = new JLayeredPane();
    private JPanel panelBlue = new JPanel();
    private JPanel panelGreen = new JPanel();
    public Main()
    {
        frame.setPreferredSize(new Dimension(600, 400));
        frame.setLayout(new BorderLayout());
        frame.add(lpane, BorderLayout.CENTER);
        lpane.setBounds(0, 0, 600, 400);
        panelBlue.setBackground(Color.BLUE);
        panelBlue.setBounds(0, 0, 600, 400);
        panelBlue.setOpaque(true);
        panelGreen.setBackground(Color.GREEN);
        panelGreen.setBounds(200, 100, 100, 100);
        panelGreen.setOpaque(true);
        lpane.add(panelBlue, new Integer(0), 0);
        lpane.add(panelGreen, new Integer(1), 0);
        frame.pack();
        frame.setVisible(true);
    }


    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        new Main();
    }

}

You use setBounds to position the panels inside the layered pane and also to set their sizes.

Edit to reflect changes to original post You will need to add component listeners that detect when the parent container is being resized and then dynamically change the bounds of panel A and B.

Update: As suggested by a commenter (additional credit to How can I disable the spell checker on text inputs on the iPhone), use this to handle all desktop and mobile browsers.

<tag autocomplete="off" autocorrect="off" autocapitalize="off" spellcheck="false"/>

Original answer: Javascript cannot override user settings, so unless you use another mechanism other than textfields, this is not (or shouldn't be) possible.

Here is a working exemple :

printf("-%s-", (char[2]){'A', 0});

This will display -A-

there is a good library to use its called djagno-nomad, although not directly related to the question asked, thought of sharing this,

scenario: most of the time when switching to project, we feel like it should revert our changes that we did on this current branch, that's what exactly this library does, checkout below

https://pypi.org/project/django-nomad/

You can always point to your home directory using ~ then you can refer to your data folder.

import pandas as pd
df = pd.read_csv("~/mydata/data.csv")

For your case, it should be like this

import pandas as pd
df = pd.read_csv("~/folder/folder2/data_folder/data.csv")

You can also set your data directory as a prefix

import pandas as pd
DATA_DIR = "~/folder/folder2/data_folder/"
df = pd.read_csv(DATA_DIR+"data.csv")

You can take advantage of f-strings as @nikos-tavoularis said

import pandas as pd
DATA_DIR = "~/folder/folder2/data_folder/"
FILE_NAME = "data.csv"
df = pd.read_csv(f"{DATA_DIR}{FILE_NAME}")

<input type="text" class="input-control" placeholder="My Input">   

Add the following CSS in your head section.

<style type="text/css">
    .input-control::placeholder { /* Chrome, Firefox, Opera, Safari 10.1+ */
                    color: red !important;
                    opacity: 1; /* Firefox */
    }
        
     .input-control:-ms-input-placeholder { /* Internet Explorer 10-11 */
                    color: red !important;
     }
        
     .input-control::-ms-input-placeholder { /* Microsoft Edge */
                    color: red !important;
     }
</style>

The following is the reference link. https://www.w3schools.com/howto/howto_css_placeholder.asp

In my case, I wanted to see .htaccess files, but not all the other .* resources.
In Zend Studio for Eclipse, in PHP Explorer (not Remote System Explorer), click the downward facing arrow (next to the left/right arrows).
Choose Filters.
Uncheck .* resources
In the "Name filter patterns" area, type the filenames you want to ignore.
I used: .svn, .cvs, .DS_Store, .buildpath, .project

SVG

Would recommend using svg for graphical elements. While using css to style your elements.

#box {_x000D_
  fill: orange;_x000D_
  stroke: black;_x000D_
}

<svg>_x000D_
  <rect id="box" x="0" y="0" width="50" height="50"/>_x000D_
</svg>

Incase arguments have spaces in it, you can pass like shown below.

java -jar myjar.jar 'first argument' 'second argument'

$percentage = 50;
$totalWidth = 350;

$new_width = ($percentage / 100) * $totalWidth;

1) Allow remote connect to MySQL. Edit file:

>sudo nano /etc/mysql/my.cnf

Comment line:

#bind-address       = 127.0.0.1

Restart MySQL:

>sudo service mysql restart

2) Create user for remote connection.

>mysql -uroot -p

CREATE USER 'developer'@'localhost' IDENTIFIED BY 'dev_password';
CREATE USER 'developer'@'%' IDENTIFIED BY 'dev_password';

GRANT ALL ON *.* TO 'developer'@'localhost';
GRANT ALL ON *.* TO 'developer'@'%';

3) In my case I need to connect remotely from Windows to VirtualBox machine with Ubuntu. So I need to allow port 3306 in iptables:

>iptables -A INPUT -i eth0 -p tcp -m tcp --dport 3306 -j ACCEPT

UPDATE March 2016

By Android Support Library 23.2.1 of a support library version. So all WRAP_CONTENT should work correctly.

Please update version of a library in gradle file.

compile 'com.android.support:recyclerview-v7:23.2.1'

This allows a RecyclerView to size itself based on the size of its contents. This means that previously unavailable scenarios, such as using WRAP_CONTENT for a dimension of the RecyclerView, are now possible.

you’ll be required to call setAutoMeasureEnabled(true)

Fixed bugs related to various measure-spec methods in update

Check https://developer.android.com/topic/libraries/support-library/features.html

Here's another option, which is less efficient but more concise. It's how I generally handle this sort of problem:

Get-ChildItem -Recurse .\targetdir -Exclude *.log |
  Where-Object { $_.FullName -notmatch '\\excludedir($|\\)' }

The \\excludedir($|\\)' expression allows you to exclude the directory and its contents at the same time.

Update: Please check the excellent answer from msorens for an edge case flaw with this approach, and a much more fleshed out solution overall.

You can do something like that in pure html using an <object> tag:
<div><object data="file.txt"></object></div>

This method has some limitations though, like, it won't fit size of the block to the content - you have to specify width and height manually. And styles won't be applied to the text.

I found another case and therefore I thing you are all wrong.

This is what I had:

/usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../x86_64-suse-linux/bin/ld: eggtrayicon.o: undefined reference to symbol 'XFlush'
/usr/lib64/libX11.so.6: error adding symbols: DSO missing from command line

The problem is that the command line DID NOT contain -lX11 - although the libX11.so should be added as a dependency because there were also GTK and GNOME libraries in the arguments.

So, the only explanation for me is that this message might have been intended to help you, but it didn't do it properly. This was probably simple: the library that provides the symbol was not added to the command line.

Please note three important rules concerning linkage in POSIX:

• Dynamic libraries have defined dependencies, so only libraries from the top-dependency should be supplied in whatever order (although after the static libraries)
• Static libraries have just undefined symbols - it's up to you to know their dependencies and supply all of them in the command line
• The order in static libraries is always: requester first, provider follows. Otherwise you'll get undefined symbol message, just like when you forgot to add the library to the command line
• When you specify the library with -l<name>, you never know whether it will take lib<name>.so or lib<name>.a. The dynamic library is preferred, if found, and static libraries only can be enforced by compiler option - that's all. And whether you have any problems as above, it depends on whether you had static or dynamic libraries
• Well, sometimes the dependencies may be lacking in dynamic libraries :D

In the step 5 of Phil, "Resources" is no longer available in the new version of the Chrome. You need to click the page icon just beside the Ajax page listed in the bottom pane with the columns of Name, Method, Status, ...

Then it will show you more panels where you will find the error messages.

You define var scatterSeries = [];, and then try to parse it as a json string at console.info(JSON.parse(scatterSeries)); which obviously fails. The variable is converted to an empty string, which causes an "unexpected end of input" error when trying to parse it.

You could probably use an inheritance structure although the more I played with this the dirtier I felt.

class AnimalEnum:
  @classmethod
  def verify(cls, other):
    return issubclass(other.__class__, cls)


class Dog(AnimalEnum):
  pass

def do_something(thing_that_should_be_an_enum):
  if not AnimalEnum.verify(thing_that_should_be_an_enum):
    raise OhGodWhy

In Eclipse if you turn on the option "Escape text when pasting into a string literal" (in Preferences > Java > Editor > Typing) and paste a multi-lined string whithin quotes, it will automatically add " and \n" + for all your lines.

String str = "paste your text here";

The keepNA = TRUE option prevents problems with NA

nchar(NA)
## [1] 2
nchar(NA, keepNA=TRUE)
## [1] NA

Try this one:

 $ find . -name "*.txt" -type f -print | xargs file | grep "foo=" | cut -d: -f1

Founded here: http://www.unix.com/shell-programming-scripting/42573-search-files-excluding-binary-files.html

There's no such feature today, the CTRL+SHIFT+O == CTRL+P @ doesn't work for all languages.

As a last resort you can use the search panel - although it is not so fast an easy to use as you'd like - you can enter this regex in the search panel to find all functions:

function\s([_A-Za-z0-9]+)\s*\(

The user who originally created the SQL view or procedure has been deleted. If you recreate that user, it should address your error.

results = context.Orders.Where(o => o.OrderDate <= today && today <= o.OrderDate)

The select is uneeded as you are already working with an order.

You can change it in you php-configuration on your webserver. Search in php.ini for

session.gc_maxlifetime() The value is set in Seconds.

The ls command has a parameter -t to sort by time. You can then grab the first (newest) with head -1.

ls -t b2* | head -1

But beware: Why you shouldn't parse the output of ls

My personal opinion: parsing ls is only dangerous when the filenames can contain funny characters like spaces or newlines. If you can guarantee that the filenames will not contain funny characters then parsing ls is quite safe.

If you are developing a script which is meant to be run by many people on many systems in many different situations then I very much do recommend to not parse ls.

Here is how to do it "right": How can I find the latest (newest, earliest, oldest) file in a directory?

unset -v latest
for file in "$dir"/*; do
  [[ $file -nt $latest ]] && latest=$file
done

This may be OLD, but here is the best answer:

    float dist = (float) Math.sqrt(
            Math.pow(x1 - x2, 2) +
            Math.pow(y1 - y2, 2) );

I use the following format and works well.

robocopy \\SourceServer\Path \\TargetServer\Path filename.txt

to copy everything you can replace filename.txt with *.* and there are plenty of other switches to copy subfolders etc... see here: http://ss64.com/nt/robocopy.html

Update: As the comment below says, this answer is obsolete.

As everyone else has said, @require only gets run when the script has installed. However, you should note as well that currently jQuery 1.4.* doesn't work with greasemonkey. You can see here for details: http://forum.jquery.com/topic/importing-jquery-1-4-1-into-greasemonkey-scripts-generates-an-error

You will have to use jQuery 1.3.2 until things change.

Try Case

SELECT   stock.name,
      CASE 
         WHEN stock.quantity <20 THEN 'Buy urgent'
         ELSE 'There is enough'
      END
FROM stock

You have VisualTkinter also known as Visual Python. Development seems not active. You have sourceforge and googlecode sites. Web site is here.

On the other hand, you have PAGE that seems active and works in python 2.7 and py3k

As you indicate on your comment, none of these use the grid geometry. As far as I can say the only GUI builder doing that could probably be Komodo Pro GUI Builder which was discontinued and made open source in ca. 2007. The code was located in the SpecTcl repository.

It seems to install fine on win7 although has not used it yet. This is an screenshot from my PC:

By the way, Rapyd Tk also had plans to implement grid geometry as in its documentation says it is not ready 'yet'. Unfortunately it seems 'nearly' abandoned.

dumps takes an object and produces a string:

>>> a = {'foo': 3}
>>> json.dumps(a)
'{"foo": 3}'

load would take a file-like object, read the data from that object, and use that string to create an object:

with open('file.json') as fh:
    a = json.load(fh)

Note that dump and load convert between files and objects, while dumps and loads convert between strings and objects. You can think of the s-less functions as wrappers around the s functions:

def dump(obj, fh):
    fh.write(dumps(obj))

def load(fh):
    return loads(fh.read())

No, unlike in a lot of other languages, XSLT variables cannot change their values after they are created. You can however, avoid extraneous code with a technique like this:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="xml" indent="yes" omit-xml-declaration="yes"/>

  <xsl:variable name="mapping">
    <item key="1" v1="A" v2="B" />
    <item key="2" v1="X" v2="Y" />
  </xsl:variable>
  <xsl:variable name="mappingNode"
                select="document('')//xsl:variable[@name = 'mapping']" />

  <xsl:template match="....">
    <xsl:variable name="testVariable" select="'1'" />

    <xsl:variable name="values" select="$mappingNode/item[@key = $testVariable]" />

    <xsl:variable name="variable1" select="$values/@v1" />
    <xsl:variable name="variable2" select="$values/@v2" />
  </xsl:template>
</xsl:stylesheet>

In fact, once you've got the values variable, you may not even need separate variable1 and variable2 variables. You could just use $values/@v1 and $values/@v2 instead.

There is no error when I use your code,

but I am calling the hasLetter method like this:

hasLetter("a",words);

Beamer just delegates responsibility for managing layout of itemize environments back to the base LaTeX packages, so there's nothing funky you need to do in Beamer itself to alter the apperaance / layout of your lists.

Since Beamer redefines itemize, item, etc., the fully proper way to manipulate things like indentation is to redefine the Beamer templates. I get the impression that you're not looking to go that far, but if that's not the case, let me know and I'll elaborate.

There are at least three ways of accomplishing your goal from within your document, without mussing about with Beamer templates.

With itemize

In the following code snippet, you can change the value of \itemindent from 0em to whatever you please, including negative values. 0em is the default item indentation.

The advantage of this method is that the list is styled normally. The disadvantage is that Beamer's redefinition of itemize and \item means that the number of paramters that can be manipulated to change the list layout is limited. It can be very hard to get the spacing right with multi-line items.

\begin{itemize}
  \setlength{\itemindent}{0em}
  \item This is a normally-indented item.
\end{itemize}

With list

In the following code snippet, the second parameter to \list is the bullet to use, and the third parameter is a list of layout parameters to change. The \leftmargin parameter adjusts the indentation of the entire list item and all of its rows; \itemindent alters the indentation of subsequent lines.

The advantage of this method is that you have all of the flexibility of lists in non-Beamer LaTeX. The disadvantage is that you have to setup the bullet style (and other visual elements) manually (or identify the right command for the template you're using). Note that if you leave the second argument empty, no bullet will be displayed and you'll save some horizontal space.

\begin{list}{$\square$}{\leftmargin=1em \itemindent=0em}
  \item This item uses the margin and indentation provided above.
\end{list}

Defining a customlist environment

The shortcomings of the list solution can be ameliorated by defining a new customlist environment that basically redefines the itemize environment from Beamer but also incorporates the \leftmargin and \itemindent (etc.) parameters. Put the following in your preamble:

\makeatletter
\newenvironment{customlist}[2]{
  \ifnum\@itemdepth >2\relax\@toodeep\else
      \advance\@itemdepth\@ne%
      \beamer@computepref\@itemdepth%
      \usebeamerfont{itemize/enumerate \beameritemnestingprefix body}%
      \usebeamercolor[fg]{itemize/enumerate \beameritemnestingprefix body}%
      \usebeamertemplate{itemize/enumerate \beameritemnestingprefix body begin}%
      \begin{list}
        {
            \usebeamertemplate{itemize \beameritemnestingprefix item}
        }
        { \leftmargin=#1 \itemindent=#2
            \def\makelabel##1{%
              {%  
                  \hss\llap{{%
                    \usebeamerfont*{itemize \beameritemnestingprefix item}%
                        \usebeamercolor[fg]{itemize \beameritemnestingprefix item}##1}}%
              }%  
            }%  
        }
  \fi
}
{
  \end{list}
  \usebeamertemplate{itemize/enumerate \beameritemnestingprefix body end}%
}
\makeatother

Now, to use an itemized list with custom indentation, you can use the following environment. The first argument is for \leftmargin and the second is for \itemindent. The default values are 2.5em and 0em respectively.

\begin{customlist}{2.5em}{0em}
   \item Any normal item can go here.
\end{customlist}

A custom bullet style can be incorporated into the customlist solution using the standard Beamer mechanism of \setbeamertemplate. (See the answers to this question on the TeX Stack Exchange for more information.)

Alternatively, the bullet style can just be modified directly within the environment, by replacing \usebeamertemplate{itemize \beameritemnestingprefix item} with whatever bullet style you'd like to use (e.g. $\square$).

php.net/mb_detect_encoding

echo mb_detect_encoding($str, "auto");

or

echo mb_detect_encoding($str, "UTF-8, ASCII, ISO-8859-1");

i really don't know what the results are, but i'd suggest you just take some of your feeds with different encodings and try if mb_detect_encoding works or not.

update
auto is short for "ASCII,JIS,UTF-8,EUC-JP,SJIS". it returns the detected charset, which you can use to convert the string to utf-8 with iconv.

<?php
function convertToUTF8($str) {
    $enc = mb_detect_encoding($str);

    if ($enc && $enc != 'UTF-8') {
        return iconv($enc, 'UTF-8', $str);
    } else {
        return $str;
    }
}
?>

i haven't tested it, so no guarantee. and maybe there's a simpler way.

You can get this if the client specifies "https" but the server is only running "http". So, the server isn't expecting to make a secure connection.

Not really. for backward compatibility it is 32 bits.
If you want 64 bits you have long, size_t or int64_t

In your layout xml do the following:

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">

    <solid android:color="@android:color/holo_red_dark" />

    <corners android:radius="32dp" />

</shape>

By changing the android:radius you can change the amount of "radius" of the corners.

<solid> is used to define the color of the drawable.

You can use replace android:radius with android:bottomLeftRadius, android:bottomRightRadius, android:topLeftRadius and android:topRightRadius to define radius for each corner.

This works for me :

<style>
   .WidgetBody
        {   
            background: #F0F0F0;
            background-image:url('images/mini-loader.gif');
            background-position: 50% 50%;            
            background-repeat:no-repeat;            
        }
</style>        

it works

Add this inside your head tag

<link rel="shortcut icon" href="http://example.com/myicon.png" />

$ sudo killall node in another terminal works on mac, while killall node not working:

$ killall node

I use the following with a private github repository:

npm install github:mygithubuser/myproject

You can either use regex, or keep on using str_replace.

Eg.

$url = parse_url($_SERVER['REQUEST_URI']);

if ($url != '/') {
    parse_str($url['query']);
    echo $id;
    echo $othervar;
}

Output will be: http://www.testing.com/123/123

Yes, you can do this. The knack you need is the concept that there are two ways of getting tables out of the table server. One way is ..

FROM TABLE A

The other way is

FROM (SELECT col as name1, col2 as name2 FROM ...) B

Notice that the select clause and the parentheses around it are a table, a virtual table.

So, using your second code example (I am guessing at the columns you are hoping to retrieve here):

SELECT a.attr, b.id, b.trans, b.lang
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, a.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)

Notice that your real table attribute is the first table in this join, and that this virtual table I've called b is the second table.

This technique comes in especially handy when the virtual table is a summary table of some kind. e.g.

SELECT a.attr, b.id, b.trans, b.lang, c.langcount
FROM attribute a
JOIN (
 SELECT at.id AS id, at.translation AS trans, at.language AS lang, at.attribute
 FROM attributeTranslation at
) b ON (a.id = b.attribute AND b.lang = 1)
JOIN (
 SELECT count(*) AS langcount,  at.attribute
 FROM attributeTranslation at
 GROUP BY at.attribute
) c ON (a.id = c.attribute)

See how that goes? You've generated a virtual table c containing two columns, joined it to the other two, used one of the columns for the ON clause, and returned the other as a column in your result set.

Just the heads up, there seems to be special CSS class for this called form-horizontal

input-append has another side effect, that it drops font-size to zero

Why don't you simply use set_index method?

In : col = ['a','b','c']

In : data = DataFrame([[1,2,3],[10,11,12],[20,21,22]],columns=col)

In : data
Out:
    a   b   c
0   1   2   3
1  10  11  12
2  20  21  22

In : data2 = data.set_index('a')

In : data2
Out:
     b   c
a
1    2   3
10  11  12
20  21  22

If you want it visually formatted to two decimals as a string (for output) use toFixed():

var priceString = someValue.toFixed(2);

The answer by @David has two problems:

1. It leaves the result as a floating point number, and consequently holds the possibility of displaying a particular result with many decimal places, e.g. 134.1999999999 instead of "134.20".

2. If your value is an integer or rounds to one tenth, you will not see the additional decimal value:

   var n = 1.099;
   (Math.round( n * 100 )/100 ).toString() //-> "1.1"
   n.toFixed(2)                            //-> "1.10"
   
   var n = 3;
   (Math.round( n * 100 )/100 ).toString() //-> "3"
   n.toFixed(2)                            //-> "3.00"
   

And, as you can see above, using toFixed() is also far easier to type. ;)

int index = std::distance(std::begin(myArray), std::find(begin(myArray), end(std::myArray), VALUE));

Returns an invalid index (length of the array) if not found.

Assuming a simple table:

CREATE TABLE dbo.foo(ID INT IDENTITY(1,1), name SYSNAME);

We can capture IDENTITY values in a table variable for further consumption.

DECLARE @IDs TABLE(ID INT);

-- minor change to INSERT statement; add an OUTPUT clause:
INSERT dbo.foo(name) 
  OUTPUT inserted.ID INTO @IDs(ID)
SELECT N'Fred'
UNION ALL
SELECT N'Bob';

SELECT ID FROM @IDs;

The nice thing about this method is (a) it handles multi-row inserts (SCOPE_IDENTITY() only returns the last value) and (b) it avoids this parallelism bug, which can lead to wrong results, but so far is only fixed in SQL Server 2008 R2 SP1 CU5.

Type:

type = list.AsEnumerable().SingleOrDefault().GetType();

If you are using more than one libraries of firebase then make sure that the version are same.

Before:
  compile 'com.google.firebase:firebase-database:9.2.0'
    compile 'com.google.firebase:firebase-storage:9.2.0'
    compile 'com.firebaseui:firebase-ui-database:0.4.0'
    compile 'com.squareup.picasso:picasso:2.5.2'
    compile 'com.google.firebase:firebase-auth:9.0.2'

After:  compile 'com.google.firebase:firebase-database:9.2.0'
    compile 'com.google.firebase:firebase-storage:9.2.0'
    compile 'com.firebaseui:firebase-ui-database:0.4.0'
    compile 'com.squareup.picasso:picasso:2.5.2'
    compile 'com.google.firebase:firebase-auth:9.2.0'

in my case i have used auth with 9.0.2 .So i changed to 9.2.0

It allows servlets to have multiple servlet mappings:

<servlet>
    <servlet-name>Servlet1</servlet-name>
    <servlet-path>foo.Servlet</servlet-path>
</servlet>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/enroll</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/pay</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>Servlet1</servlet-name>
    <url-pattern>/bill</url-pattern>
</servlet-mapping>

It allows filters to be mapped on the particular servlet:

<filter-mapping>
    <filter-name>Filter1</filter-name>
    <servlet-name>Servlet1</servlet-name>
</filter-mapping>

Your proposal would support neither of them. Note that the web.xml is read and parsed only once during application's startup, not on every HTTP request as you seem to think.

Since Servlet 3.0, there's the @WebServlet annotation which minimizes this boilerplate:

@WebServlet("/enroll")
public class Servlet1 extends HttpServlet {

Or, if you're kicking it old school:

cd /path/to/other/repository
patch -p1 < 0001-whatever.patch

Since you've already stashed your changes, all you need is this one-liner:

• git stash branch <branchname> [<stash>]

From the docs (https://www.kernel.org/pub/software/scm/git/docs/git-stash.html):

Creates and checks out a new branch named <branchname> starting from the commit at which the <stash> was originally created, applies the changes recorded in <stash> to the new working tree and index. If that succeeds, and <stash> is a reference of the form stash@{<revision>}, it then drops the <stash>. When no <stash> is given, applies the latest one.

This is useful if the branch on which you ran git stash save has changed enough that git stash apply fails due to conflicts. Since the stash is applied on top of the commit that was HEAD at the time git stash was run, it restores the originally stashed state with no conflicts.

String.matches is the way to do pattern matching in the regex sense.

But as a handy aside, word.firstLetter in real Scala code looks like:

word(0)

Scala treats Strings as a sequence of Char's, so if for some reason you wanted to explicitly get the first character of the String and match it, you could use something like this:

"Cat"(0).toString.matches("[a-cA-C]")
res10: Boolean = true

I'm not proposing this as the general way to do regex pattern matching, but it's in line with your proposed approach to first find the first character of a String and then match it against a regex.

EDIT: To be clear, the way I would do this is, as others have said:

"Cat".matches("^[a-cA-C].*")
res14: Boolean = true

Just wanted to show an example as close as possible to your initial pseudocode. Cheers!

It's not practical to parse URLs using regex. A full implementation of the RFC1738 rules would result in an enormously long regex (assuming it's even possible). Certainly your current expression fails many valid URLs, and passes invalid ones.

Instead:

a. use a proper URL parser that actually follows the real rules. (I don't know of one for JavaScript; it would probably be overkill. You could do it on the server side though). Or,

b. just trim away any leading or trailing spaces, then check it has one of your preferred schemes on the front (typically ‘http://’ or ‘https://’), and leave it at that. Or,

c. attempt to use the URL and see what lies at the end, for example by sending it am HTTP HEAD request from the server-side. If you get a 404 or connection error, it's probably wrong.

it return true even if url is something like "http://wwww".

Well, that is indeed a perfectly valid URL.

If you want to check whether a hostname such as ‘wwww’ actually exists, you have no choice but to look it up in the DNS. Again, this would be server-side code.

You can simply use one line javascript in browser console to convert a hex map key to base64. Open console in latest browser (F12 on Windows, ? Option+? Command+I on macOS, Ctrl+? Shift+I on Linux) and paste the code and replace the SHA-1, SHA-256 hex map that Google Play provides under Release Setup App signing:

Hex map key to Base64 key hash

> btoa('a7:77:d9:20:c8:01:dd:fa:2c:3b:db:b2:ef:c5:5a:1d:ae:f7:28:6f'.split(':').map(hc => String.fromCharCode(parseInt(hc, 16))).join(''))
< "p3fZIMgB3fosO9uy78VaHa73KG8="

You can also convert it here; run the below code snippet and paste hex map key and hit convert button:

document.getElementById('convert').addEventListener('click', function() {
  document.getElementById('result').textContent = btoa(
    document.getElementById('hex-map').value
      .split(':')
      .map(hc => String.fromCharCode(parseInt(hc, 16)))
      .join('')
  );
});

<textarea id="hex-map" placeholder="paste hex key map here" style="width: 100%"></textarea>
<button id="convert">Convert</button>
<p><code id="result"></code></p>

And if you want to reverse a key hash to check and validate it:

Reverse Base64 key hash to hex map key

> atob('p3fZIMgB3fosO9uy78VaHa73KG8=').split('').map(c => c.charCodeAt(0).toString(16)).join(':')
< "a7:77:d9:20:c8:1:dd:fa:2c:3b:db:b2:ef:c5:5a:1d:ae:f7:28:6f"

document.getElementById('convert').addEventListener('click', function() {
  document.getElementById('result').textContent = atob(document.getElementById('base64-hash').value)
    .split('')
    .map(c => c.charCodeAt(0).toString(16))
    .join(':')
});

<textarea id="base64-hash" placeholder="paste base64 key hash here" style="width: 100%"></textarea>
<button id="convert">Convert</button>
<p><code id="result"></code></p>

You can try to use the parameter "enable-automation"

var options = new ChromeOptions();

// hide selenium
options.AddExcludedArguments(new List<string>() { "enable-automation" });

var driver = new ChromeDriver(ChromeDriverService.CreateDefaultService(), options);

But, I want to warn that this ability was fixed in ChromeDriver 79.0.3945.16. So probably you should use older versions of chrome.

Also, as another option, you can try using InternetExplorerDriver instead of Chrome. As for me, IE does not block at all without any hacks.

And for more info try to take a look here:

Selenium webdriver: Modifying navigator.webdriver flag to prevent selenium detection

Unable to hide "Chrome is being controlled by automated software" infobar within Chrome v76

Here are some differences:

1. You can call app.render on root level and res.render only inside a route/middleware.

2. app.render always returns the html in the callback function, whereas res.render does so only when you've specified the callback function as your third parameter. If you call res.render without the third parameter/callback function the rendered html is sent to the client with a status code of 200.

   Take a look at the following examples.

   • app.render

     app.render('index', {title: 'res vs app render'}, function(err, html) {
         console.log(html)
     });
     
     // logs the following string (from default index.jade)
     <!DOCTYPE html><html><head><title>res vs app render</title><link rel="stylesheet" href="/stylesheets/style.css"></head><body><h1>res vs app render</h1><p>Welcome to res vs app render</p></body></html>
     

   • res.render without third parameter

     app.get('/render', function(req, res) {
         res.render('index', {title: 'res vs app render'})
     })
     
     // also renders index.jade but sends it to the client 
     // with status 200 and content-type text/html on GET /render
     

   • res.render with third parameter

     app.get('/render', function(req, res) {
         res.render('index', {title: 'res vs app render'}, function(err, html) {
             console.log(html);
             res.send('done');
         })
     })
     
     // logs the same as app.render and sends "done" to the client instead 
     // of the content of index.jade
     

3. res.render uses app.render internally to render template files.

4. You can use the render functions to create html emails. Depending on your structure of your app, you might not always have acces to the app object.

   For example inside an external route:

   app.js

   var routes = require('routes');
   
   app.get('/mail', function(req, res) {
       // app object is available -> app.render
   })
   
   app.get('/sendmail', routes.sendmail);
   

   ---

   routes.js

   exports.sendmail = function(req, res) {
       // can't use app.render -> therefore res.render
   }
   

void Console()
{
    AllocConsole();
    FILE *pFileCon = NULL;
    pFileCon = freopen("CONOUT$", "w", stdout);

    COORD coordInfo;
    coordInfo.X = 130;
    coordInfo.Y = 9000;

    SetConsoleScreenBufferSize(GetStdHandle(STD_OUTPUT_HANDLE), coordInfo);
    SetConsoleMode(GetStdHandle(STD_OUTPUT_HANDLE),ENABLE_QUICK_EDIT_MODE| ENABLE_EXTENDED_FLAGS);
}

int main(int argc, char *argv[])
{
    Console();
    std::cout<<"start@@";
    qDebug()<<"start!";

You can't use std::cout as others have said,my way is perfect even for some code can't include "qdebug" !

You have a lot of variants for using @RequestParam with additional optional elements, e.g.

@RequestParam(required = false, defaultValue = "someValue", value="someAttr") String someAttr

If you don't put required = false - param will be required by default.

defaultValue = "someValue" - the default value to use as a fallback when the request parameter is not provided or has an empty value.

If request and method param are the same - you don't need value = "someAttr"

If your csv file contains extra data, columns can be deleted from the DataFrame after import.

import pandas as pd
from StringIO import StringIO

csv = r"""dummy,date,loc,x
bar,20090101,a,1
bar,20090102,a,3
bar,20090103,a,5
bar,20090101,b,1
bar,20090102,b,3
bar,20090103,b,5"""

df = pd.read_csv(StringIO(csv),
        index_col=["date", "loc"], 
        usecols=["dummy", "date", "loc", "x"],
        parse_dates=["date"],
        header=0,
        names=["dummy", "date", "loc", "x"])
del df['dummy']

Which gives us:

                x
date       loc
2009-01-01 a    1
2009-01-02 a    3
2009-01-03 a    5
2009-01-01 b    1
2009-01-02 b    3
2009-01-03 b    5
