However you opened the port, you close it in the same way. For example, if you created a socket, bound it to port 0.0.0.0:5955, and called listen, close that same socket.

You can also just kill the process that has the port open.

If you want to find out what process has a port open, try this:

lsof -i :5955

If you want to know whether a port is open, you can do the same lsof command (if any process has it open, it's open; otherwise, it's not), or you can just try to connect to it, e.g.:

nc localhost 5955

If it returns immediately with no output, the port isn't open.

It may be worth mentioning that, technically speaking, it's not a port that's open, but a host:port combination. For example, if you're plugged into a LAN as 10.0.1.2, you could bind a socket to 127.0.0.1:5955, or 10.0.1.2:5955, without either one affecting the other, or you could bind to 0.0.0.0:5955 to handle both at once. You can see all of your computer's IPv4 and IPv6 addresses with the ifconfig command.

Try ssh -t -t(or ssh -tt for short) to force pseudo-tty allocation even if stdin isn't a terminal.

See also: Terminating SSH session executed by bash script

From ssh manpage:

-T      Disable pseudo-tty allocation.

-t      Force pseudo-tty allocation.  This can be used to execute arbitrary 
        screen-based programs on a remote machine, which can be very useful,
        e.g. when implementing menu services.  Multiple -t options force tty
        allocation, even if ssh has no local tty.

When filtering a DataFrame with string values, I find that the pyspark.sql.functions lower and upper come in handy, if your data could have column entries like "foo" and "Foo":

import pyspark.sql.functions as sql_fun
result = source_df.filter(sql_fun.lower(source_df.col_name).contains("foo"))

NVL(value, default) is the function you are looking for.

select type, craft, sum(NVL(regular, 0) + NVL(overtime, 0) ) as total_hours
from hours_t
group by type, craft
order by type, craft

Oracle have 5 NULL-related functions:

1. NVL
2. NVL2
3. COALESCE
4. NULLIF
5. LNNVL

NVL:

NVL(expr1, expr2)

NVL lets you replace null (returned as a blank) with a string in the results of a query. If expr1 is null, then NVL returns expr2. If expr1 is not null, then NVL returns expr1.

NVL2 :

NVL2(expr1, expr2, expr3)

NVL2 lets you determine the value returned by a query based on whether a specified expression is null or not null. If expr1 is not null, then NVL2 returns expr2. If expr1 is null, then NVL2 returns expr3.

COALESCE

COALESCE(expr1, expr2, ...)

COALESCE returns the first non-null expr in the expression list. At least one expr must not be the literal NULL. If all occurrences of expr evaluate to null, then the function returns null.

NULLIF

NULLIF(expr1, expr2)

NULLIF compares expr1 and expr2. If they are equal, then the function returns null. If they are not equal, then the function returns expr1. You cannot specify the literal NULL for expr1.

LNNVL

LNNVL(condition)

LNNVL provides a concise way to evaluate a condition when one or both operands of the condition may be null.

# Goole Maps API.
link = 'http://maps.googleapis.com/maps/api/directions/json?origin=Chicago,IL&destination=Los+Angeles,CA&waypoints=Joplin,MO|Oklahoma+City,OK&sensor=false'

# Request data from link as 'str'
data = requests.get(link).text

# convert 'str' to Json
data = json.loads(data)

# Now you can access Json 
for i in data['routes'][0]['legs'][0]['steps']:
    lattitude = i['start_location']['lat']
    longitude = i['start_location']['lng']
    print('{}, {}'.format(lattitude, longitude))

I have implemented a solution for:

• Dynamic fragment replacement inside the tab
• Maintenance of the history per tab
• Working with orientation changes

The tricks to achieve this are the following:

• Use the notifyDataSetChanged() method to apply the fragment replacement
• Use the fragment manager only for back stage and no for fragament replacement
• Maintain the history using the memento pattern (stack)

The adapter code is the following:

public class TabsAdapter extends FragmentStatePagerAdapter implements ActionBar.TabListener, ViewPager.OnPageChangeListener {

/** The sherlock fragment activity. */
private final SherlockFragmentActivity mActivity;

/** The action bar. */
private final ActionBar mActionBar;

/** The pager. */
private final ViewPager mPager;

/** The tabs. */
private List<TabInfo> mTabs = new LinkedList<TabInfo>();

/** The total number of tabs. */
private int TOTAL_TABS;

private Map<Integer, Stack<TabInfo>> history = new HashMap<Integer, Stack<TabInfo>>();

/**

 *
 * @param activity the activity
 * @param pager    the pager
 */
public TabsAdapter(SherlockFragmentActivity activity, ViewPager pager) {
    super(activity.getSupportFragmentManager());
    activity.getSupportFragmentManager();
    this.mActivity = activity;
    this.mActionBar = activity.getSupportActionBar();
    this.mPager = pager;
    mActionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

The very first time you add all tabs, we need to call the method createHistory(), to create the initial history

public void createHistory() {
    int position = 0;
    TOTAL_TABS = mTabs.size();
    for (TabInfo mTab : mTabs) {
        if (history.get(position) == null) {
            history.put(position, new Stack<TabInfo>());
        }
        history.get(position).push(new TabInfo(mTab.fragmentClass, mTab.args));
        position++;
    }
}

Every time you want to replace a fragment to a specific tab you call: replace(final int position, final Class fragmentClass, final Bundle args)

/* Save the fragment to the history. */
    mActivity.getSupportFragmentManager().beginTransaction().addToBackStack(null).commit();

    /* Update the tabs. */
    updateTabs(new TabInfo(fragmentClass, args), position);

    /* Updates the history. */
    history.get(position).push(new TabInfo(mTabs.get(position).fragmentClass, mTabs.get(position).args));

    notifyDataSetChanged();

On back pressed you need to call the back() method:

public void back() {
    int position = mActionBar.getSelectedTab().getPosition();
    if (!historyIsEmpty(position)) {
        /* In case there is not any other item in the history, then finalize the activity. */
        if (isLastItemInHistory(position)) {
            mActivity.finish();
        }
        final TabInfo currentTabInfo = getPrevious(position);
        mTabs.clear();
        for (int i = 0; i < TOTAL_TABS; i++) {
            if (i == position) {
                mTabs.add(new TabInfo(currentTabInfo.fragmentClass, currentTabInfo.args));
            } else {
                TabInfo otherTabInfo = history.get(i).peek();
                mTabs.add(new TabInfo(otherTabInfo.fragmentClass, otherTabInfo.args));
            }
        }
    }
    mActionBar.selectTab(mActionBar.getTabAt(position));
    notifyDataSetChanged();
}

The solution works with sherlock action bar and with swipe gesture.

1. go to your image in windows and copy it
2. go to the res folder and select one of the drawable folders and paste the image in there
3. click on imageview then go to properties and scroll down until you see src
4. insert this into src @drawable/imagename

As we all know storing password in clear text in database is not secure. the bcrypt is a hashing password technique.It is used to built password security. one of the amazing function of bcrypt is it save us from hackers it is used to protect the password from hacking attacks because the password is stored in bcrypted form.

the password_hash() function is used to create a new password hash. It uses a strong & robust hashing algorithm.The password_hash() function is very much compatible with the crypt() function. Therefore, password hashes created by crypt() may be used with password_hash() and vice-versa. The functions password_verify() and password_hash() just the wrappers around the function crypt(), and they make it much easier to use it accurately.

SYNTAX

string password_hash($password , $algo , $options)

The following algorithms are currently supported by password_hash() function:

PASSWORD_DEFAULT PASSWORD_BCRYPT PASSWORD_ARGON2I PASSWORD_ARGON2ID

Parameters: This function accepts three parameters as mentioned above and described below:

password: It stores the password of the user. algo: It is the password algorithm constant that is used continuously while denoting the algorithm which is to be used when the hashing of password takes place. options: It is an associative array, which contains the options. If this is removed and doesn’t include, a random salt is going to be used, and the utilization of a default cost will happen. Return Value: It returns the hashed password on success or False on failure.

Example:

Input : echo password_hash("GFG@123", PASSWORD_DEFAULT); Output : $2y$10$.vGA19Jh8YrwSJFDodbfoHJIOFH)DfhuofGv3Fykk1a

Below programs illustrate the password_hash() function in PHP:

<?php echo password_hash("GFG@123", PASSWORD_DEFAULT); ?>

OUTPUT

$2y$10$Z166W1fBdsLcXPVQVfPw/uRq1ueWMA6sLt9bmdUFz9AmOGLdM393G

I have got this error when trying to create JPA entity with the name "User" (in Postgres) that is reserved. So the way it is resolved is to change the table name by @Table annotation:

@Entity
@Table(name="users")
public class User {..}

Or change the table name manually.

I think you haven't messed up yet. Try:

git reset HEAD^

This will bring the dir to state before you've made the commit, HEAD^ means the parent of the current commit (the one you don't want anymore), while keeping changes from it (unstaged).

export in sh and related shells (such as bash), marks an environment variable to be exported to child-processes, so that the child inherits them.

export is defined in POSIX:

The shell shall give the export attribute to the variables corresponding to the specified names, which shall cause them to be in the environment of subsequently executed commands. If the name of a variable is followed by = word, then the value of that variable shall be set to word.

You need to open a new window:

window.open(url);

https://developer.mozilla.org/en-US/docs/DOM/window.open

<a style="cursor:pointer"
  onclick=" window.open('http://YOUR.URL.TARGET','',' scrollbars=yes,menubar=no,width=500, resizable=yes,toolbar=no,location=no,status=no')">Your text</a>

Since I18n is the Rails core feature starting from version 2.2 you can use its localize-method. By applying the forementioned strftime %-variables you can specify the desired format under config/locales/en.yml (or whatever language), in your case like this:

time:
  formats:
    default: '%FT%T'

Or if you want to use this kind of format in a few specific places you can refer it as a variable like this

time:
  formats:
    specific_format: '%FT%T'

After that you can use it in your views like this:

l(Mode.last.created_at, format: :specific_format)  

I wrote an unzipper in Javascript. It works.

It relies on Andy G.P. Na's binary file reader and some RFC1951 inflate logic from notmasteryet. I added the ZipFile class.

working example:
http://cheeso.members.winisp.net/Unzip-Example.htm (dead link)

The source:
http://cheeso.members.winisp.net/srcview.aspx?dir=js-unzip (dead link)

NB: the links are dead; I'll find a new host soon.

Included in the source is a ZipFile.htm demonstration page, and 3 distinct scripts, one for the zipfile class, one for the inflate class, and one for a binary file reader class. The demo also depends on jQuery and jQuery UI. If you just download the js-zip.zip file, all of the necessary source is there.

Here's what the application code looks like in Javascript:

// In my demo, this gets attached to a click event.
// it instantiates a ZipFile, and provides a callback that is
// invoked when the zip is read.  This can take a few seconds on a
// large zip file, so it's asynchronous. 
var readFile = function(){
    $("#status").html("<br/>");
    var url= $("#urlToLoad").val();
    var doneReading = function(zip){
        extractEntries(zip);
    };

    var zipFile = new ZipFile(url, doneReading);
};


// this function extracts the entries from an instantiated zip
function extractEntries(zip){
    $('#report').accordion('destroy');

    // clear
    $("#report").html('');

    var extractCb = function(id) {
        // this callback is invoked with the entry name, and entry text
        // in my demo, the text is just injected into an accordion panel.
        return (function(entryName, entryText){
            var content = entryText.replace(new RegExp( "\\n", "g" ), "<br/>");
            $("#"+id).html(content);
            $("#status").append("extract cb, entry(" + entryName + ")  id(" + id + ")<br/>");
            $('#report').accordion('destroy');
            $('#report').accordion({collapsible:true, active:false});
        });
    }

    // for each entry in the zip, extract it. 
    for (var i=0; i<zip.entries.length;  i++) {
        var entry = zip.entries[i];

        var entryInfo = "<h4><a>" + entry.name + "</a></h4>\n<div>";

        // contrive an id for the entry, make it unique
        var randomId = "id-"+ Math.floor((Math.random() * 1000000000));

        entryInfo += "<span class='inputDiv'><h4>Content:</h4><span id='" + randomId +
            "'></span></span></div>\n";

        // insert the info for one entry as the last child within the report div
        $("#report").append(entryInfo);

        // extract asynchronously
        entry.extract(extractCb(randomId));
    }
}

The demo works in a couple of steps: The readFile fn is triggered by a click, and instantiates a ZipFile object, which reads the zip file. There's an asynchronous callback for when the read completes (usually happens in less than a second for reasonably sized zips) - in this demo the callback is held in the doneReading local variable, which simply calls extractEntries, which just blindly unzips all the content of the provided zip file. In a real app you would probably choose some of the entries to extract (allow the user to select, or choose one or more entries programmatically, etc).

The extractEntries fn iterates over all entries, and calls extract() on each one, passing a callback. Decompression of an entry takes time, maybe 1s or more for each entry in the zipfile, which means asynchrony is appropriate. The extract callback simply adds the extracted content to an jQuery accordion on the page. If the content is binary, then it gets formatted as such (not shown).

It works, but I think that the utility is somewhat limited.

For one thing: It's very slow. Takes ~4 seconds to unzip the 140k AppNote.txt file from PKWare. The same uncompress can be done in less than .5s in a .NET program. EDIT: The Javascript ZipFile unpacks considerably faster than this now, in IE9 and in Chrome. It is still slower than a compiled program, but it is plenty fast for normal browser usage.

For another: it does not do streaming. It basically slurps in the entire contents of the zipfile into memory. In a "real" programming environment you could read in only the metadata of a zip file (say, 64 bytes per entry) and then read and decompress the other data as desired. There's no way to do IO like that in javascript, as far as I know, therefore the only option is to read the entire zip into memory and do random access in it. This means it will place unreasonable demands on system memory for large zip files. Not so much a problem for a smaller zip file.

Also: It doesn't handle the "general case" zip file - there are lots of zip options that I didn't bother to implement in the unzipper - like ZIP encryption, WinZip encryption, zip64, UTF-8 encoded filenames, and so on. (EDIT - it handles UTF-8 encoded filenames now). The ZipFile class handles the basics, though. Some of these things would not be hard to implement. I have an AES encryption class in Javascript; that could be integrated to support encryption. Supporting Zip64 would probably useless for most users of Javascript, as it is intended to support >4gb zipfiles - don't need to extract those in a browser.

I also did not test the case for unzipping binary content. Right now it unzips text. If you have a zipped binary file, you'd need to edit the ZipFile class to handle it properly. I didn't figure out how to do that cleanly. It does binary files now, too.

EDIT - I updated the JS unzip library and demo. It now does binary files, in addition to text. I've made it more resilient and more general - you can now specify the encoding to use when reading text files. Also the demo is expanded - it shows unzipping an XLSX file in the browser, among other things.

So, while I think it is of limited utility and interest, it works. I guess it would work in Node.js.

mysql 5.4 provides a native split function:

SPLIT_STR(<column>, '<delimiter>', <index>)

Unless you plan on creating your own drop down list (and not using a standard library drop down list), you are stuck. The DDL control's look is going to be based upon the system you are running and/or the browser that is rendering the output.

rm -rf .git should suffice. That will blow away all Git-related information.

private static final int[] CDRIVES = new int[] {0xe0, 0xf4, ...};

and after access convert to byte.

I think the problem is that you are using type="text" instead of textarea. What you want is:

<textarea class="span6" rows="3" placeholder="What's up?" required></textarea>

To clarify, a type="text" will always be one row, where-as a textarea can be multiple.

I needed to find out how many duplicates there were and what they were so I wrote a function building off of what Naveed had posted earlier:

def print_duplicates(array)
  puts "Array count: #{array.count}"
  map = {}
  total_dups = 0
  array.each do |v|
    map[v] = (map[v] || 0 ) + 1
  end

  map.each do |k, v|
    if v != 1
      puts "#{k} appears #{v} times"
      total_dups += 1
    end
  end
  puts "Total items that are duplicated: #{total_dups}"
end

In your selector you seem to be attempting to fetch some nested element of your radio button with a given id. If you want to check a radio button, you should select this radio button in the selector and not something else:

$('input:radio[name="cols"]').attr('checked', 'checked');

This assumes that you have the following radio button in your markup:

<input type="radio" name="cols" value="1" />

If your radio button had an id:

<input type="radio" name="cols" value="1" id="myradio" />

you could directly use an id selector:

$('#myradio').attr('checked', 'checked');

The best practice for this, in my opinion is:

TimeUnit.DAYS.toMillis(1);     // 1 day to milliseconds.
TimeUnit.MINUTES.toMillis(23); // 23 minutes to milliseconds.
TimeUnit.HOURS.toMillis(4);    // 4 hours to milliseconds.
TimeUnit.SECONDS.toMillis(96); // 96 seconds to milliseconds.

Arrgh, I can't get the code to show up correctly. Sorry, I got it working. Sorry again, I don't think I read the question properly.

String  foo[] = {"a","cc","a","dd"},
remove = "a";
boolean gaps[] = new boolean[foo.length];
int newlength = 0;

for (int c = 0; c<foo.length; c++)
{
    if (foo[c].equals(remove))
    {
        gaps[c] = true;
        newlength++;
    }
    else 
        gaps[c] = false;

    System.out.println(foo[c]);
}

String newString[] = new String[newlength];

System.out.println("");

for (int c1=0, c2=0; c1<foo.length; c1++)
{
    if (!gaps[c1])
    {
        newString[c2] = foo[c1];
        System.out.println(newString[c2]);
        c2++;
    }
}

The RemoveAll method should do the trick:

parameterList.RemoveAll(delegate (object o) { return o == null; });

For the carousel, I believe all images have to be exactly the same height and width.

Also, when you refer back to the scaffolding page from bootstrap, I'm pretty sure that span16 = 940px. With this in mind, I think we can assume that if you have a

<div class="row">
     <div class="span4"> 
        <!--left content div guessing around 235px in width -->
     </div>
     <div class="span8">
        <!--right content div guessing around 470px in width -->
     </div>
</div>

So yes, you have to be careful when setting the spans space within a row because if the image width is to large, it will send your div over into the next "row" and that is no fun :P

I was using spring boot 1.5.10 and tries to exclude logback, the given solution above did not work well, I use configurations instead

configurations.all {
    exclude group: "org.springframework.boot", module:"spring-boot-starter-logging"
}

There is a very simple mental mapping in response that was a bit hard to find in the other answers:

• done implements tap as in bluebird Promises

• then implements then as in ES6 Promises

You can do it by using attr, the mistake that you made is that you put the true inside quotes. instead of that try this:

$("input").attr("required", true);

I think you need this ..

Dim n as Integer   

For n = 5 to 17
  msgbox cells(n,3) '--> sched waste
  msgbox cells(n,4) '--> type of treatm
  msgbox format(cells(n,5),"dd/MM/yyyy") '--> Lic exp
  msgbox cells(n,6) '--> email col
Next

try:
    whatever()
except:
    # this will catch any exception or error

It is worth mentioning this is not proper Python coding. This will catch also many errors you might not want to catch.

Regex for remove white space

\s+

var str = "Visit Microsoft!";
var res = str.replace(/\s+/g, "");
console.log(res);

or

[ ]+

var str = "Visit Microsoft!";
var res = str.replace(/[ ]+/g, "");
console.log(res);

Remove all white space at begin of string

^[ ]+

var str = "    Visit Microsoft!";
var res = str.replace(/^[ ]+/g, "");
console.log(res);

remove all white space at end of string

[ ]+$

var str = "Visit Microsoft!      ";
var res = str.replace(/[ ]+$/g, "");
console.log(res);

This answer may appear at the surface to be unrelated, but there is an indirect cause of this error message.

First, the "Uses VFP register..." error message is directly caused from mixing mfloat-abi=soft and mfloat-abi=hard options within your build. This setting must be consistent for all objects that are to be linked. This fact is well covered in the other answers to this question.

The indirect cause of this error may be due to the Eclipse editor getting confused by a self-inflicted error in the project's ".cproject" file. The Eclipse editor frequently reswizzles file links and sometimes it breaks itself when you make changes to your directory structures or file locations. This can also affect the path settings to your gcc compiler - and only for a subset of your project's files. While I'm not yet sure of exactly what causes this failure, replacing the .cproject file with a backup copy corrected this problem for me. In my case I noticed .java.null.pointer errors after adding an include directory path and started receiving the "VFP register error" messages out of the blue. In the build log I noticed that a different path to the gcc compiler was being used for some of my sources that were local to the workspace, but not all of them!? The two gcc compilers were using different float settings for unknown reasons - hence the VFP register error.

I compared the .cproject settings with a older copy and observed differences in entries for the sources causing the trouble - even though the overriding of project settings was disabled. By replacing the .cproject file with the old version the problem went away, and I'm leaving this answer as a reminder of what happened.

Although there are many ways to do this. But if you want to do it in an easy way and want to format text before writing it to log file. You can create a helper function for this.

if (!function_exists('logIt')) {
    function logIt($logMe)
    {
        $logFilePath = storage_path('logs/cron.log.'.date('Y-m-d').'.log');
        $cronLogFile = fopen($logFilePath, "a");
        fwrite($cronLogFile, date('Y-m-d H:i:s'). ' : ' .$logMe. PHP_EOL);
        fclose($cronLogFile);
    }
}

Simplest way? It works. :)

    Dim queryString As String = "Stor_Proc_Name " & data1 & "," & data2
    Try
        Using connection As New SqlConnection(ConnStrg)
            connection.Open()
            Dim command As New SqlCommand(queryString, connection)
            Dim reader As SqlDataReader = command.ExecuteReader()
            Dim DTResults As New DataTable

            DTResults.Load(reader)
            MsgBox(DTResults.Rows(0)(0).ToString)

        End Using
    Catch ex As Exception
        MessageBox.Show("Error while executing .. " & ex.Message, "")
    Finally
    End Try

ntext, text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

Even though above answers are correct, I wanna add a notice to distinguish types of storage:

• Internal storage: It should say 'private storage' because it belongs to the app and cannot be shared. Where it's saved is based on where the app installed. If the app was installed on an SD card (I mean the external storage card you put more into a cell phone for more space to store images, videos, ...), your file will belong to the app means your file will be in an SD card. And if the app was installed on an Internal card (I mean the onboard storage card coming with your cell phone), your file will be in an Internal card.
• External storage: It should say 'public storage' because it can be shared. And this mode divides into 2 groups: private external storage and public external storage. Basically, they are nearly the same, you can consult more from this site: https://developer.android.com/training/data-storage/files
• A real SD card (I mean the external storage card you put more into a cell phone for more space to store images, videos, ...): this was not stated clearly on Android docs, so many people might be confused with how to save files in this card.

Here is the link to source code for cases I mentioned above: https://github.com/mttdat/utils/blob/master/utils/src/main/java/mttdat/utils/FileUtils.java

I think you are trying to run some utility or shell script from UNIX\LINUX which has some GUI. Anyways

SOLUTION: dude all you need is an XServer & X11 forwarding enabled. I use XMing (XServer). You are already enabling X11 forwarding. Just Install it(XMing) and keep it running when you create the session with PuTTY.

Include the following code in your class code.

 def __iter__(self):
        for x in self.iterable:
            yield x

Make sure that you replace self.iterablewith the iterable which you iterate through.

Here's an example code

class someClass:
    def __init__(self,list):
        self.list = list
    def __iter__(self):
        for x in self.list:
            yield x


var = someClass([1,2,3,4,5])
for num in var: 
    print(num) 

Output

1
2
3
4
5

Note: Since strings are also iterable, they can also be used as an argument for the class

foo = someClass("Python")
for x in foo:
    print(x)

Output

P
y
t
h
o
n

You can try with this

nFilter.style.cssText = 'width:330px;float:left;';

That should do it for you.

Command go

Download and install packages and dependencies

Usage:

go get [-d] [-f] [-t] [-u] [-v] [-fix] [-insecure] [build flags] [packages]

Get downloads the packages named by the import paths, along with their dependencies. It then installs the named packages, like 'go install'.

The -d flag instructs get to stop after downloading the packages; that is, it instructs get not to install the packages.

The -f flag, valid only when -u is set, forces get -u not to verify that each package has been checked out from the source control repository implied by its import path. This can be useful if the source is a local fork of the original.

The -fix flag instructs get to run the fix tool on the downloaded packages before resolving dependencies or building the code.

The -insecure flag permits fetching from repositories and resolving custom domains using insecure schemes such as HTTP. Use with caution.

The -t flag instructs get to also download the packages required to build the tests for the specified packages.

The -u flag instructs get to use the network to update the named packages and their dependencies. By default, get uses the network to check out missing packages but does not use it to look for updates to existing packages.

The -v flag enables verbose progress and debug output.

Get also accepts build flags to control the installation. See 'go help build'.

When checking out a new package, get creates the target directory GOPATH/src/. If the GOPATH contains multiple entries, get uses the first one. For more details see: 'go help gopath'.

When checking out or updating a package, get looks for a branch or tag that matches the locally installed version of Go. The most important rule is that if the local installation is running version "go1", get searches for a branch or tag named "go1". If no such version exists it retrieves the default branch of the package.

When go get checks out or updates a Git repository, it also updates any git submodules referenced by the repository.

Get never checks out or updates code stored in vendor directories.

For more about specifying packages, see 'go help packages'.

For more about how 'go get' finds source code to download, see 'go help importpath'.

This text describes the behavior of get when using GOPATH to manage source code and dependencies. If instead the go command is running in module-aware mode, the details of get's flags and effects change, as does 'go help get'. See 'go help modules' and 'go help module-get'.

See also: go build, go install, go clean.

The solution below has a "SEO friendlier" version:

function hyphenize($string) {
    $dict = array(
        "I'm"      => "I am",
        "thier"    => "their",
        // Add your own replacements here
    );
    return strtolower(
        preg_replace(
          array( '#[\\s-]+#', '#[^A-Za-z0-9. -]+#' ),
          array( '-', '' ),
          // the full cleanString() can be downloaded from http://www.unexpectedit.com/php/php-clean-string-of-utf8-chars-convert-to-similar-ascii-char
          cleanString(
              str_replace( // preg_replace can be used to support more complicated replacements
                  array_keys($dict),
                  array_values($dict),
                  urldecode($string)
              )
          )
        )
    );
}

function cleanString($text) {
    $utf8 = array(
        '/[áàâãªä]/u'   =>   'a',
        '/[ÁÀÂÃÄ]/u'    =>   'A',
        '/[ÍÌÎÏ]/u'     =>   'I',
        '/[íìîï]/u'     =>   'i',
        '/[éèêë]/u'     =>   'e',
        '/[ÉÈÊË]/u'     =>   'E',
        '/[óòôõºö]/u'   =>   'o',
        '/[ÓÒÔÕÖ]/u'    =>   'O',
        '/[úùûü]/u'     =>   'u',
        '/[ÚÙÛÜ]/u'     =>   'U',
        '/ç/'           =>   'c',
        '/Ç/'           =>   'C',
        '/ñ/'           =>   'n',
        '/Ñ/'           =>   'N',
        '/–/'           =>   '-', // UTF-8 hyphen to "normal" hyphen
        '/[’‘‹›‚]/u'    =>   ' ', // Literally a single quote
        '/[“”«»„]/u'    =>   ' ', // Double quote
        '/ /'           =>   ' ', // nonbreaking space (equiv. to 0x160)
    );
    return preg_replace(array_keys($utf8), array_values($utf8), $text);
}

The rationale for the above functions (which I find way inefficient - the one below is better) is that a service that shall not be named apparently ran spelling checks and keyword recognition on the URLs.

After losing a long time on a customer's paranoias, I found out they were not imagining things after all -- their SEO experts [I am definitely not one] reported that, say, converting "Viaggi Economy Perù" to viaggi-economy-peru "behaved better" than viaggi-economy-per (the previous "cleaning" removed UTF8 characters; Bogotà became bogot, Medellìn became medelln and so on).

There were also some common misspellings that seemed to influence the results, and the only explanation that made sense to me is that our URL were being unpacked, the words singled out, and used to drive God knows what ranking algorithms. And those algorithms apparently had been fed with UTF8-cleaned strings, so that "Perù" became "Peru" instead of "Per". "Per" did not match and sort of took it in the neck.

In order to both keep UTF8 characters and replace some misspellings, the faster function below became the more accurate (?) function above. $dict needs to be hand tailored, of course.

Previous answer

A simple approach:

// Remove all characters except A-Z, a-z, 0-9, dots, hyphens and spaces
// Note that the hyphen must go last not to be confused with a range (A-Z)
// and the dot, NOT being special (I know. My life was a lie), is NOT escaped

$str = preg_replace('/[^A-Za-z0-9. -]/', '', $str);

// Replace sequences of spaces with hyphen
$str = preg_replace('/  */', '-', $str);

// The above means "a space, followed by a space repeated zero or more times"
// (should be equivalent to / +/)

// You may also want to try this alternative:
$str = preg_replace('/\\s+/', '-', $str);

// where \s+ means "zero or more whitespaces" (a space is not necessarily the
// same as a whitespace) just to be sure and include everything

Note that you might have to first urldecode() the URL, since %20 and + both are actually spaces - I mean, if you have "Never%20gonna%20give%20you%20up" you want it to become Never-gonna-give-you-up, not Never20gonna20give20you20up . You might not need it, but I thought I'd mention the possibility.

So the finished function along with test cases:

function hyphenize($string) {
    return 
    ## strtolower(
          preg_replace(
            array('#[\\s-]+#', '#[^A-Za-z0-9. -]+#'),
            array('-', ''),
        ##     cleanString(
              urldecode($string)
        ##     )
        )
    ## )
    ;
}

print implode("\n", array_map(
    function($s) {
            return $s . ' becomes ' . hyphenize($s);
    },
    array(
    'Never%20gonna%20give%20you%20up',
    "I'm not the man I was",
    "'Légeresse', dit sa majesté",
    )));


Never%20gonna%20give%20you%20up    becomes  never-gonna-give-you-up
I'm not the man I was              becomes  im-not-the-man-I-was
'Légeresse', dit sa majesté        becomes  legeresse-dit-sa-majeste

To handle UTF-8 I used a cleanString implementation found online (link broken since, but a stripped down copy with all the not-too-esoteric UTF8 characters is at the beginning of the answer; it's also easy to add more characters to it if you need) that converts UTF8 characters to normal characters, thus preserving the word "look" as much as possible. It could be simplified and wrapped inside the function here for performance.

The function above also implements converting to lowercase - but that's a taste. The code to do so has been commented out.

Try this code:

    $(function() { 
        // ...

        var $body = $(document);
        $body.bind('scroll', function() {
            if ($body.scrollLeft() !== 0) {
                $body.scrollLeft(0);
            }
        });

        // ...
    });

As mentioned you can sort by:

• Making your object implement Comparable
• Or pass a Comparator to Collections.sort

If you do both, the Comparable will be ignored and Comparator will be used. This helps that the value objects has their own logical Comparable which is most reasonable sort for your value object, while each individual use case has its own implementation.

Like this: ^[^0-9]+$

Explanation:

• ^ matches the beginning of the string
• [^...] matches anything that isn't inside
• 0-9 means any character between 0 and 9
• + matches one or more of the previous thing
• $ matches the end of the string

I have searched for this a few minutes and i couldn't find any working code.

But now i finaly did it ! Take a look:

<div class="input-group" id="unified-inputs">
<input type="text" class="form-control" placeholder="MinVal" />
<input type="text" class="form-control" placeholder="MaxVal" />
</div>

And css

#unified-inputs.input-group { width: 100%; }
#unified-inputs.input-group input { width: 50% !important; }
#unified-inputs.input-group input:last-of-type { border-left: 0; }

Dead simple solution for Double numbers (keep it mind that this is not the best user-friendly solution), in your UITextFieldDelegate delegate:

func textField(_ textField: UITextField,
               shouldChangeCharactersIn range: NSRange,
               replacementString string: String) -> Bool {
        guard let currentString = textField.text as NSString? else {
            return false
        }
        let newString = currentString.replacingCharacters(in: range, with: string)
        return Double(newString) != nil
}

I would use GCJ (GNU Compiler for Java) in your situation. It's an AOT (ahead of time) compiler for Java, much like GCC is for C. Instead of interpreting code, or generating intermediate java code to be run at a later time by the Java VM, it generates machine code.

GCJ is available on almost any Linux system through its respective package manager (if available). After installation, the GCJ compiler should be added to the path so that it can be invoked through the terminal. If you're using Windows, you can download and install GCJ through Cygwin or MinGW.

I would strongly recommend, however, that you rewrite your source for another language that is meant to be compiled, such as C++. Java is meant to be a portable, interpreted language. Compiling it to machine code is completely against what the language was developed for.

Objective-C doesn't have named parameters, so everything on the left side of a colon is part of the method name. For example,

getBusStops: forTime:

is the name of the method. The name is broken up so it can be more descriptive. You could simply name your method

getBusStops: :

but that doesn't tell you much about the second parameter.

You want to make filter dynamic then you have to use Lambda like

from django.db.models import Q

brands = ['ABC','DEF' , 'GHI']

queryset = Product.objects.filter(reduce(lambda x, y: x | y, [Q(brand=item) for item in brands]))

reduce(lambda x, y: x | y, [Q(brand=item) for item in brands]) is equivalent to

Q(brand=brands[0]) | Q(brand=brands[1]) | Q(brand=brands[2]) | .....

You should try not open the file with a folder-explorer method (i.e. file://), but open that file from http:// (i.e. http://yoursite.com/ from http://localhost/)

If you can guarantee the 7-zip app will be installed (and in the path) on all target machines, you can offload by calling the command line app 7z. Not the most elegant solution but it is the least work.

According to it

No value was specified for the AUTO_INCREMENT column, so MySQL assigned sequence numbers automatically. You can also explicitly assign NULL or 0 to the column to generate sequence numbers.

You can get this in following way,

DateTimeFormatInfo mfi = new DateTimeFormatInfo();
string strMonthName = mfi.GetMonthName(8).ToString(); //August

Now, get first three characters

string shortMonthName = strMonthName.Substring(0, 3); //Aug

This happened to me yesterday. What happened was that when I added the device Xcode included it in the wrong profile by default. This is easier to fix now that Apple has updated the provisioning portal:

1. Log in to developer.apple.com/ios and click Certificates, Identifiers & Profiles
2. Click devices and make sure that the device in question is listed
3. Click provisioning profiles > All and select the one you want to use
4. Click the edit button
5. You will see another devices list which also has a label which will probably say "3 of 4 devices selected" or something of that nature.
6. Check the select all box or scroll through the list and check the device. If your device was unchecked, this is your problem.
7. Click "Generate"
8. DON'T hit Download & Install – while this will work it's likely to screw up your project file if you've already installed the provisioning profile (see this question for more info).
9. Open Xcode, open the Organizer, switch to the Devices tab, and hit the Refresh button in the lower right corner. This will pull in the changes to the provisioning profile.

Now it should work.

You can use this code to find HyperLink in GridView. Use of e.Row.Cells[0].Controls[0] to find First position of control in GridView.

To plot multiple graphs on the same figure you will have to do:

c = a + b

plt.plot(t, a, 'r') # plotting t, a separately 
plt.plot(t, b, 'b') # plotting t, b separately 
plt.plot(t, c, 'g') # plotting t, c separately 
plt.show()

Oracle does not have a simple database model like MySQL or MS SQL Server. I find the closest thing is to query the tablespaces and the corresponding users within them.

For example, I have a DEV_DB tablespace with all my actual 'databases' within them:

SQL> SELECT TABLESPACE_NAME FROM USER_TABLESPACES;

Resulting in:

SYSTEM
SYSAUX
UNDOTBS1
TEMP
USERS
EXAMPLE
DEV_DB

It is also possible to query the users in all tablespaces:

SQL> select USERNAME, DEFAULT_TABLESPACE from DBA_USERS;

Or within a specific tablespace (using my DEV_DB tablespace as an example):

SQL> select USERNAME, DEFAULT_TABLESPACE from DBA_USERS where DEFAULT_TABLESPACE = 'DEV_DB';

ROLES DEV_DB
DATAWARE DEV_DB
DATAMART DEV_DB
STAGING DEV_DB

You can simply get it in the format you want.

BEGIN TRAN
    INSERT INTO T VALUES ('A');
    INSERT INTO T VALUES ('B');
    INSERT INTO T VALUES ('B');
    INSERT INTO T VALUES ('C');
COMMIT TRAN
SELECT * FROM T; -- Check after.
DELETE T;

            public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
                return true;
            }

        }).build();
        SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
                sslContext, NoopHostnameVerifier.INSTANCE);
        CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsf).build();

In psql that would be

\dx

See the manual for details: http://www.postgresql.org/docs/current/static/app-psql.html

Doing it in plain SQL it would be a select on pg_extension:

SELECT * 
FROM pg_extension

Here in your code demo is id where you want to display your result after click event has occur and just nothing.

You can take anything

<p id="demo">

or

<div id="demo"> 

It is just node in a document where you just want to display your result.

I use this for Zip Codes, quick and easy.

<input type="text" id="zip_code" name="zip_code" onkeypress="return event.charCode > 47 && event.charCode < 58;" pattern="[0-9]{5}" required></input>

In case someone is still searching for a query to display the difference in hr min and sec format: (This will display the difference in this format: 2 hr 20 min 22 secs)

SELECT
CAST(DATEDIFF(minute, StartDateTime, EndDateTime)/ 60 as nvarchar(20)) + ' hrs ' + CAST(DATEDIFF(second, StartDateTime, EndDateTime)/60 as nvarchar(20)) + ' mins' +          CAST(DATEDIFF(second, StartDateTime, EndDateTime)% 60 as nvarchar(20))  + ' secs'

OR can be in the format as in the question:

CAST(DATEDIFF(minute, StartDateTime, EndDateTime)/ 60 as nvarchar(20)) + ':' + CAST(DATEDIFF(second, StartDateTime, EndDateTime)/60 as nvarchar(20))

Consider using axios

axios.get( url,
{ headers: {"Content-Type": "application/json"} } ).then( res => {

  if(res.data.error) {

  } else { 
    doAnything( res.data )
  }

}).catch(function (error) {
   doAnythingError(error)
});

I had this issue using fetch and axios worked perfectly.

If the list is in random order, you can just take the first 50.

Otherwise, use

import random
random.sample(the_list, 50)

random.sample help text:

sample(self, population, k) method of random.Random instance
    Chooses k unique random elements from a population sequence.

    Returns a new list containing elements from the population while
    leaving the original population unchanged.  The resulting list is
    in selection order so that all sub-slices will also be valid random
    samples.  This allows raffle winners (the sample) to be partitioned
    into grand prize and second place winners (the subslices).

    Members of the population need not be hashable or unique.  If the
    population contains repeats, then each occurrence is a possible
    selection in the sample.

    To choose a sample in a range of integers, use xrange as an argument.
    This is especially fast and space efficient for sampling from a
    large population:   sample(xrange(10000000), 60)

Some people would say that two threads is too many - I'm not quite in that camp :-)

Here's my advice: measure, don't guess. One suggestion is to make it configurable and initially set it to 100, then release your software to the wild and monitor what happens.

If your thread usage peaks at 3, then 100 is too much. If it remains at 100 for most of the day, bump it up to 200 and see what happens.

You could actually have your code itself monitor usage and adjust the configuration for the next time it starts but that's probably overkill.

For clarification and elaboration:

I'm not advocating rolling your own thread pooling subsystem, by all means use the one you have. But, since you were asking about a good cut-off point for threads, I assume your thread pool implementation has the ability to limit the maximum number of threads created (which is a good thing).

I've written thread and database connection pooling code and they have the following features (which I believe are essential for performance):

• a minimum number of active threads.
• a maximum number of threads.
• shutting down threads that haven't been used for a while.

The first sets a baseline for minimum performance in terms of the thread pool client (this number of threads is always available for use). The second sets a restriction on resource usage by active threads. The third returns you to the baseline in quiet times so as to minimise resource use.

You need to balance the resource usage of having unused threads (A) against the resource usage of not having enough threads to do the work (B).

(A) is generally memory usage (stacks and so on) since a thread doing no work will not be using much of the CPU. (B) will generally be a delay in the processing of requests as they arrive as you need to wait for a thread to become available.

That's why you measure. As you state, the vast majority of your threads will be waiting for a response from the database so they won't be running. There are two factors that affect how many threads you should allow for.

The first is the number of DB connections available. This may be a hard limit unless you can increase it at the DBMS - I'm going to assume your DBMS can take an unlimited number of connections in this case (although you should ideally be measuring that as well).

Then, the number of threads you should have depend on your historical use. The minimum you should have running is the minimum number that you've ever had running + A%, with an absolute minimum of (for example, and make it configurable just like A) 5.

The maximum number of threads should be your historical maximum + B%.

You should also be monitoring for behaviour changes. If, for some reason, your usage goes to 100% of available for a significant time (so that it would affect the performance of clients), you should bump up the maximum allowed until it's once again B% higher.

In response to the "what exactly should I measure?" question:

What you should measure specifically is the maximum amount of threads in concurrent use (e.g., waiting on a return from the DB call) under load. Then add a safety factor of 10% for example (emphasised, since other posters seem to take my examples as fixed recommendations).

In addition, this should be done in the production environment for tuning. It's okay to get an estimate beforehand but you never know what production will throw your way (which is why all these things should be configurable at runtime). This is to catch a situation such as unexpected doubling of the client calls coming in.

row=5
col=5
[[x]*col for x in [b for b in range(row)]]

The above will give you a 5x5 2D array

[[0, 0, 0, 0, 0],
 [1, 1, 1, 1, 1],
 [2, 2, 2, 2, 2],
 [3, 3, 3, 3, 3],
 [4, 4, 4, 4, 4]]

It is using nested list comprehension. Breakdown as below:

[[x]*col for x in [b for b in range(row)]]

[x]*col --> final expression that is evaluated
for x in --> x will be the value provided by the iterator
[b for b in range(row)]] --> Iterator.

[b for b in range(row)]] this will evaluate to [0,1,2,3,4] since row=5
so now it simplifies to

[[x]*col for x in [0,1,2,3,4]]

This will evaluate to [[0]*5 for x in [0,1,2,3,4]] --> with x=0 1st iteration
[[1]*5 for x in [0,1,2,3,4]] --> with x=1 2nd iteration
[[2]*5 for x in [0,1,2,3,4]] --> with x=2 3rd iteration
[[3]*5 for x in [0,1,2,3,4]] --> with x=3 4th iteration
[[4]*5 for x in [0,1,2,3,4]] --> with x=4 5th iteration

long millisecond = beginupd.getTime();

Date.getTime() JavaDoc states:

Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT represented by this Date object.

it's simple, use the "-B" option to add .h files' dir to search path.

E.g. g++ -B /header_file.h your.cpp -o bin/your_command

In 99.9% of all cases it is bad program design to share non-constant, global variables between files. There are very few cases when you actually need to do this: they are so rare that I cannot come up with any valid cases. Declarations of hardware registers perhaps.

In most of the cases, you should either use (possibly inlined) setter/getter functions ("public"), static variables at file scope ("private"), or incomplete type implementations ("private") instead.

In those few rare cases when you need to share a variable between files, do like this:

// file.h
extern int my_var;

// file.c
#include "file.h"
int my_var = something;

// main.c
#include "file.h"
use(my_var);

Never put any form of variable definition in a h-file.

Within your click handler, the mistake is the .validate() method; it only initializes the plugin, it does not validate the form.

To eliminate the need to have a submit button within the form, use .valid() to trigger a validation check...

$('#btn').on('click', function() {
    $("#form1").valid();
});

jsFiddle Demo

.validate() - to initialize the plugin (with options) once on DOM ready.

.valid() - to check validation state (boolean value) or to trigger a validation test on the form at any time.

Otherwise, if you had a type="submit" button within the form container, you would not need a special click handler and the .valid() method, as the plugin would capture that automatically.

Demo without click handler

EDIT:

You also have two issues within your HTML...

<input id="field1" type="text" class="required">

• You don't need class="required" when declaring rules within .validate(). It's redundant and superfluous.

• The name attribute is missing. Rules are declared within .validate() by their name. The plugin depends upon unique name attributes to keep track of the inputs.

Should be...

<input name="field1" id="field1" type="text" />

yes you can rename pane names, and not only window names starting with tmux >= 2.3. Just type the following in your shell:

printf '\033]2;%s\033\\' 'title goes here'

you might need to add the following to your .tmux.conf to display pane names:

# Enable names for panes
set -g pane-border-status top

you can also automatically assign a name:

set -g pane-border-format "#P: #{pane_current_command}"

We should avoid using traditional for loop while working with Collections. The simple reason what I will give is that the complexity of for loop is of the order O(sqr(n)) and complexity of Iterator or even the enhanced for loop is just O(n). So it gives a performence difference.. Just take a list of some 1000 items and print it using both ways. and also print the time difference for the execution. You can sees the difference.

using Aaron's answer, this can be the short & easiest solution:

function filterSelectList(selectListId, filterId)
{
    var filter = $("#" + filterId).val().toUpperCase();

    $("#" + selectListId + " option").each(function(i){
       if ($(this).text.toUpperCase().includes(filter))
           $(this).css("display", "block");
       else
           $(this).css("display", "none");
    });
};

For vector graphics, ImageMagick has both a render resolution and an output size that are independent of each other.

Try something like

convert -density 300 image.eps -resize 1024x1024 image.jpg

Which will render your eps at 300dpi. If 300 * width > 1024, then it will be sharp. If you render it too high though, you waste a lot of memory drawing a really high-res graphic only to down sample it again. I don't currently know of a good way to render it at the "right" resolution in one IM command.

The order of the arguments matters! The -density X argument needs to go before image.eps because you want to affect the resolution that the input file is rendered at.

This is not super obvious in the manpage for convert, but is hinted at:

SYNOPSIS

convert [input-option] input-file [output-option] output-file

Rabin-Miller is a standard probabilistic primality test. (you run it K times and the input number is either definitely composite, or it is probably prime with probability of error 4^-K. (a few hundred iterations and it's almost certainly telling you the truth)

There is a non-probabilistic (deterministic) variant of Rabin Miller.

The Great Internet Mersenne Prime Search (GIMPS) which has found the world's record for largest proven prime (2^74,207,281 - 1 as of June 2017), uses several algorithms, but these are primes in special forms. However the GIMPS page above does include some general deterministic primality tests. They appear to indicate that which algorithm is "fastest" depends upon the size of the number to be tested. If your number fits in 64 bits then you probably shouldn't use a method intended to work on primes of several million digits.

Use the method setAnimation(null) to stop an animation, it exposed as public method in View.java, it is the base class for all widgets, which are used to create interactive UI components (buttons, text fields, etc.). /** * Sets the next animation to play for this view. * If you want the animation to play immediately, use * {@link #startAnimation(android.view.animation.Animation)} instead. * This method provides allows fine-grained * control over the start time and invalidation, but you * must make sure that 1) the animation has a start time set, and * 2) the view's parent (which controls animations on its children) * will be invalidated when the animation is supposed to * start. * * @param animation The next animation, or null. */ public void setAnimation(Animation animation)

You may also be able to use the Duration class. E.g.

Date currentDate = new Date();
Date oneDayFromCurrentDate = new Date(currentDate.getTime() - Duration.ofDays(1).toMillis());

Regardless of how do you index the pushbacks your vector contains 10 elements indexed from 0 (0, 1, ..., 9). So in your second loop v[j] is invalid, when j is 10.

This will fix the error:

for(int j = 9;j >= 0;--j)
{
    cout << v[j];
}

In general it's better to think about indexes as 0 based, so I suggest you change also your first loop to this:

for(int i = 0;i < 10;++i)
{
    v.push_back(i);
}

Also, to access the elements of a container, the idiomatic approach is to use iterators (in this case: a reverse iterator):

for (vector<int>::reverse_iterator i = v.rbegin(); i != v.rend(); ++i)
{
    std::cout << *i << std::endl;
}

How about the Omondo Plugin for Eclipse. I have used it and I find it to be quite useful. Although if you are generating diagrams for large sources, you might have to start Eclipse with more memory.

Here's another simple way using Runnable interface in Thread Constructor

public class Demo {
    public static void main(String[] args) {
        Thread t1 = new Thread(new Runnable() {

            @Override
            public void run() {
                for(int i = 0; i < 5; i++){
                    try {
                        Thread.sleep(3000);
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    System.out.println("Thread T1 : "+i);
                }
            }
        });

        Thread t2 = new Thread(new Runnable() {

            @Override
            public void run() {
                for(int i = 0; i < 5; i++) {
                    try {
                        Thread.sleep(3000);
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    System.out.println("Thread T2 : "+i);
                }
            }
        });

        Thread t3 = new Thread(new Runnable() {

            @Override
            public void run() {
                for(int i = 0; i < 5; i++){
                    try {
                        Thread.sleep(3000);
                    } catch (InterruptedException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    System.out.println("Thread T3 : "+i);
                }
            }
        });

        t1.start();
        t2.start();
        t3.start();
    }
}

You have to assign the returned value of the setInterval function to a variable

var interval;
$(document).on('ready',function(){
    interval = setInterval(updateDiv,3000);
});

and then use clearInterval(interval) to clear it again.

Anticipating that I already had the answer, which is that there is no built-in worksheet function that returns the background color of a cell, I decided to review this article, in case I was wrong. I was amused to notice a citation to the very same MVP article that I used in the course of my ongoing research into colors in Microsoft Excel.

While I agree that, in the purest sense, color is not data, it is meta-data, and it has uses as such. To that end, I shall attempt to develop a function that returns the color of a cell. If I succeed, I plan to put it into an add-in, so that I can use it in any workbook, where it will join a growing legion of other functions that I think Microsoft left out of the product.

Regardless, IMO, the ColorIndex property is virtually useless, since there is essentially no connection between color indexes and the colors that can be selected in the standard foreground and background color pickers. See Color Combinations: Working with Colors in Microsoft Office and the associated binary workbook, Color_Combinations Workbook.

Your code is a no-op. By the definition of the loop, "item" has to be in Z. A "For ... in" loop in Python means "Loop though the list called 'z', each time you loop, give me the next item in the list, and call it 'item'"

http://docs.python.org/tutorial/controlflow.html#for-statements

I think your confusion arises from the fact that you're using the variable name "item" twice, to mean two different things.

Use bookmarklet. Drag this link in bookmarks, then edit and paste this code:

(function(){ var arr=[], l=document.links; var ext=prompt("select extension for download (all links containing that, will be downloaded.", ".mp3"); for(var i=0; i<l.length; i++) { if(l[i].href.indexOf(ext) !== false){ l[i].setAttribute("download",l[i].text); l[i].click(); } } })();

and go on page (from where you want to download files), and click that bookmarklet.

Posting this in an effort to help others with similar problems. I solved this issue with a five step approach -- save the context, translate the context, rotate the context, draw the text, then restore the context to its saved state.

I think of translations and transforms to the context as manipulating the coordinate grid overlaid on the canvas. By default the origin (0,0) starts in the upper left hand corner of the canvas. X increases from left to right, Y increases from top to bottom. If you make an "L" w/ your index finger and thumb on your left hand and hold it out in front of you with your thumb down, your thumb would point in the direction of increasing Y and your index finger would point in the direction of increasing X. I know it's elementary, but I find it helpful when thinking about translations and rotations. Here's why:

When you translate the context, you move the origin of the coordinate grid to a new location on the canvas. When you rotate the context, think of rotating the "L" you made with your left hand in a clockwise direction the amount indicated by the angle you specify in radians about the origin. When you strokeText or fillText, specify your coordinates in relation to the newly aligned axes. To orient your text so it's readable from bottom to top, you would translate to a position below where you want to start your labels, rotate by -90 degrees and fill or strokeText, offsetting each label along the rotated x axis. Something like this should work:

 context.save();
 context.translate(newx, newy);
 context.rotate(-Math.PI/2);
 context.textAlign = "center";
 context.fillText("Your Label Here", labelXposition, 0);
 context.restore();

.restore() resets the context back to the state it had when you called .save() -- handy for returning things back to "normal".

I have a solution for this. First thing that add is already having a string value as input() function by default takes the input as string. Second thing that you can use append method to append value of add variable in your list.

Please do check my code I have done some modification : - {1} You can enter command in capital or small or mix {2} If user entered wrong command then your program will ask to input command again

inventory = ["sword","potion","armour","bow"] print(inventory) print("\ncommands : use (remove item) and pickup (add item)") selection=input("choose a command [use/pickup] : ") while True: if selection.lower()=="use": print(inventory) remove_item=input("What do you want to use? ") inventory.remove(remove_item) print(inventory) break

 elif selection.lower()=="pickup":
      print(inventory)
      add_item=input("What do you want to pickup? ")
      inventory.append(add_item)
      print(inventory)
      break
 
 else:
      print("Invalid Command. Please check your input")
      selection=input("Once again choose a command [use/pickup] : ")

private Toolbar toolbar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    toolbar = (Toolbar) findViewById(R.id.my_toolbar);
    *// here is where you set it to show on the toolbar*
    setSupportActionBar(toolbar);
}

Well, you need to set support action bar setSupportActionBar(); and pass your variable, like so: setSupportActionBar(toolbar);

It is not entirely clear what your desired outcome is, so there is some confusion about the "correct" way of doing it in the answers and their comments. I try to give an overview and see the following three options:

Try merge and use B for conflicts

This is not the "theirs version for git merge -s ours" but the "theirs version for git merge -X ours" (which is short for git merge -s recursive -X ours):

git checkout branchA
# also uses -s recursive implicitly
git merge -X theirs branchB

This is what e.g. Alan W. Smith's answer does.

Use content from B only

This creates a merge commit for both branches but discards all changes from branchA and only keeps the contents from branchB.

# Get the content you want to keep.
# If you want to keep branchB at the current commit, you can add --detached,
# else it will be advanced to the merge commit in the next step.
git checkout branchB

# Do the merge an keep current (our) content from branchB we just checked out.
git merge -s ours branchA

# Set branchA to current commit and check it out.
git checkout -B branchA

Note that the merge commits first parent now is that from branchB and only the second is from branchA. This is what e.g. Gandalf458's answer does.

Use content from B only and keep correct parent order

This is the real "theirs version for git merge -s ours". It has the same content as in the option before (i.e. only that from branchB) but the order of parents is correct, i.e. the first parent comes from branchA and the second from branchB.

git checkout branchA

# Do a merge commit. The content of this commit does not matter,
# so use a strategy that never fails.
# Note: This advances branchA.
git merge -s ours branchB

# Change working tree and index to desired content.
# --detach ensures branchB will not move when doing the reset in the next step.
git checkout --detach branchB

# Move HEAD to branchA without changing contents of working tree and index.
git reset --soft branchA

# 'attach' HEAD to branchA.
# This ensures branchA will move when doing 'commit --amend'.
git checkout branchA

# Change content of merge commit to current index (i.e. content of branchB).
git commit --amend -C HEAD

This is what Paul Pladijs's answer does (without requiring a temporary branch).

psutil can find process by name and kill it:

import psutil

PROCNAME = "python.exe"

for proc in psutil.process_iter():
    # check whether the process name matches
    if proc.name() == PROCNAME:
        proc.kill()

I thought I would contribute by providing a concrete example of the practical use of the scale function. Say you have 3 test scores (Math, Science, and English) that you want to compare. Maybe you may even want to generate a composite score based on each of the 3 tests for each observation. Your data could look as as thus:

student_id <- seq(1,10)
math <- c(502,600,412,358,495,512,410,625,573,522)
science <- c(95,99,80,82,75,85,80,95,89,86)
english <- c(25,22,18,15,20,28,15,30,27,18)
df <- data.frame(student_id,math,science,english)

Obviously it would not make sense to compare the means of these 3 scores as the scale of the scores are vastly different. By scaling them however, you have more comparable scoring units:

z <- scale(df[,2:4],center=TRUE,scale=TRUE)

You could then use these scaled results to create a composite score. For instance, average the values and assign a grade based on the percentiles of this average. Hope this helped!

Note: I borrowed this example from the book "R In Action". It's a great book! Would definitely recommend.

java.time.Instant

Just use Instant of java.time.

    System.out.println(Instant.now());

This just printed:

2018-01-27T09:35:23.179612Z

Instant.toString always gives UTC time.

The output is usually sortable, but there are unfortunate exceptions. toString gives you enough groups of three decimals to render the precision it holds. On the Java 9 on my Mac the precision of Instant.now() seems to be microseconds, but we should expect that in approximately one case out of a thousand it will hit a whole number of milliseconds and print only three decimals. Strings with unequal numbers of decimals will be sorted in the wrong order (unless you write a custom comparator to take this into account).

Instant is one of the classes in java.time, the modern Java date and time API, which I warmly recommend that you use instead of the outdated Date class. java.time is built into Java 8 and later and has also been backported to Java 6 and 7.

Convert Lists to Collection and use removeAll

    Collection<String> listOne = new ArrayList(Arrays.asList("a","b", "c", "d", "e", "f", "g"));
    Collection<String> listTwo = new ArrayList(Arrays.asList("a","b",  "d", "e", "f", "gg", "h"));


    List<String> sourceList = new ArrayList<String>(listOne);
    List<String> destinationList = new ArrayList<String>(listTwo);


    sourceList.removeAll( listTwo );
    destinationList.removeAll( listOne );



    System.out.println( sourceList );
    System.out.println( destinationList );

Output:

[c, g]
[gg, h]

[EDIT]

other way (more clear)

  Collection<String> list = new ArrayList(Arrays.asList("a","b", "c", "d", "e", "f", "g"));

    List<String> sourceList = new ArrayList<String>(list);
    List<String> destinationList = new ArrayList<String>(list);

    list.add("boo");
    list.remove("b");

    sourceList.removeAll( list );
    list.removeAll( destinationList );


    System.out.println( sourceList );
    System.out.println( list );

Output:

[b]
[boo]

You can use onlinefontconverter.com site. It works fine and have plenty of output formats (afm bin cff dfont eot pfa pfb pfm ps pt3 suit svg t42 tfm ttc ttf woff). One of the advantages I saw, is that it export all the fonts contained inside the ttc at once (which is very convenient).

}

You could also use pdf2ps, ps2image and then convert from the resulting image to tiff with other utilities (I remember 'paul' [paul - Yet another image viewer (displays PNG, TIFF, GIF, JPG, etc.])

I know that this isn't what you asked for but LINQPad is a really great tool to teach yourself LINQ (and it's free :o).

When time isn't critical, I have been using it for the last week or so instead or a query window in SQL Server and my LINQ skills are getting better and better.

It's also a nice little code snippet tool. Its only downside is that the free version doesn't have IntelliSense.

  .web(WebApplicationType.NONE)
  .run(args);

I had to manually edit the 2 text files (httpd.conf and httpd-ssl.conf) using the Config button for Apache to run and change in notepad from 80 > 81 and 443 > 444

Using the Xampp UI config manager doesn't save the changes into Apache.

If I'm reading this question correctly, you may be missing that a jQuery mobile "button" widget is not the same thing as an HTML button element. I think this boils down to you can't call $('input').button('disable') unless you have previously called $('input').button(); to initialize a jQuery Mobile button widget on your input.

Of course, you may not want to be using jQuery button widget functionality, in which case Alexander's answer should set you right.

There is no need to put anchor. To change style of div on hover then Change background color of div on hover.

<div class="div_hover"> Change div background color on hover</div>

In .css page

.div_hover { background-color: #FFFFFF; }

.div_hover:hover { background-color: #000000; }

You can use the bit column type.

As to formulas being "updated" in the new row, since all the copying occurs after the shift, the old row (now one index up from the new row) has already had its formula shifted, so copying it to the new row will make the new row reference the old rows cells. A solution would be to parse out the formulas BEFORE the shift, then apply those (a simple String array would do the job. I'm sure you can code that in a few lines).

At start of function:

ArrayList<String> fArray = new ArrayList<String>();
Row origRow = sheet.getRow(sourceRow);
for (int i = 0; i < origRow.getLastCellNum(); i++) {
    if (origRow.getCell(i) != null && origRow.getCell(i).getCellType() == Cell.CELL_TYPE_FORMULA) 
        fArray.add(origRow.getCell(i).getCellFormula());
    else fArray.add(null);
}

Then when applying the formula to a cell:

newCell.setCellFormula(fArray.get(i));

You have to set the associatedEmployee on the Vehicle before persisting the Employee.

Employee newEmployee = new Employee("matt");
vehicle1.setAssociatedEmployee(newEmployee);
vehicles.add(vehicle1);

newEmployee.setVehicles(vehicles);

Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);

You can solve this issue be adding max-width:

#element {
   width: 100vw;
   height: 100vw;
   max-width: 100%;
}

When you using CSS to make the wrapper full width using the code width: 100vw; then you will notice a horizontal scroll in the page, and that happened because the padding and margin of html and body tags added to the wrapper size, so the solution is to add max-width: 100%

Even if I don't generally like the tone of John Gruber's Daring Fireball blog, his Larger iPhone Display Conjecture is well worth the read.

He guessed but got exactly right both the resolution in points and in pixels for both models, except that he did not (me neither) expect Apple to build a smaller resolution physical display and scale down (details are in @Tommy's answer).

The gist of it all is that one should stop thinking in terms of pixels and start thinking in terms of points (this has been the case for quite some time, it's not a recent invention) and resulting physical size of UI elements. In short, both new iPhone models improve in this regard as physically most elements remain the same size, you can just fit more of them on the screen (for each bigger screen you can fit more).

I'm just slightly disappointed they haven't kept mapping of internal resolution to actual screen resolution 1:1 for the bigger model.

The problem you are reporting seems to me caused by the following:

1. you are trying to compile C code and the source file has .cpp extension
2. you are trying to compile C++ code and the source file has .c extension

In such situation Eclipse cannot recognize the proper compiler to use.

All the answers above are helpful but none solved my issue. In my production file, my STATIC_URL was https://<URL>/static and I used the same STATIC_URL in my dev settings.py file.

This causes a silent failure in django/conf/urls/static.py.

The test elif not settings.DEBUG or '://' in prefix: picks up the '//' in the URL and does not add the static URL pattern, causing no static files to be found.

It would be thoughtful if Django spit out an error message stating you can't use a http(s):// with DEBUG = True

I had to change STATIC_URL to be '/static/'

You can also use:

driver.switch_to.frame(0)

(0) being the first iframe on the html.

to switch back to the default content:

driver.switch_to.default_content()

Yes, it is very Simple. Just Put your Code Inside this:

<androidx.core.widget.NestedScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" 
    android:layout_height="match_parent">

//YOUR CODE

</androidx.core.widget.NestedScrollView>

(function(){
    var i = 0;
    function stop(){
        clearTimeout(i);
    }

    function start(){
        i = setTimeout( timed, 1000 );
    }

    function timed(){
       document.getElementById("input").value++;
       start();
    }

    window.stop = stop;
    window.start = start;
})()

Just in case any dummies like me tried the suggestions here with a button and found nothing worked, you probably want this:

$(':button.myclass')

Run below command into the current branch folder to merge from this <commit-id> to current branch, --no-commit do not make a new commit automatically

git merge --no-commit <commit-id>

git merge --continue can only be run after the merge has resulted in conflicts.

git merge --abort Abort the current conflict resolution process, and try to reconstruct the pre-merge state.

These days a drop-down template is included in the API Gateway Console on AWS.

For your API, click on the resource name... then GET

Expand "Body Mapping Templates"

Type in

application/json

for Content-Type (must be explicitly typed out) and click the tick

A new window will open with the words "Generate template" and a dropdown (see image).

Select

Method Request passthrough

Then click save

To access any variables, just use the following syntax (this is Python) e.g. URL:

https://yourURL.execute-api.us-west-2.amazonaws.com/prod/confirmReg?token=12345&uid=5

You can get variables as follows:

from __future__ import print_function

import boto3
import json

print('Loading function')


def lambda_handler(event, context):
    print(event['params']['querystring']['token'])
    print(event['params']['querystring']['uid'])

So there is no need to explicitly name or map each variable you desire.

$output = curl_exec($ch);
$result = iconv("Windows-1251", "UTF-8", $output);

Shell scripts are run inside a subshell, and each subshell has its own concept of what the current directory is. The cd succeeds, but as soon as the subshell exits, you're back in the interactive shell and nothing ever changed there.

One way to get around this is to use an alias instead:

alias proj="cd /home/tree/projects/java"

Try out these videos egghead.io They are awesome to get started

@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
    super.onPageStarted(view, url, favicon);
    if (url.equals("your url")) {
        
            Intent intent = new Intent(view.getContext(), TransferAllDoneActivity.class);
            startActivity(intent);
        
    }
}

Even if you have indexes on some columns that are used in some queries, the fact that your 'ad-hoc' query causes a table scan shows that you don't have sufficient indexes to allow this query to complete efficiently.

For date ranges in particular it is difficult to add good indexes.

Just looking at your query, the db has to sort all the records by the selected column to be able to return the first n records.

Does the db also do a full table scan without the order by clause? Does the table have a primary key - without a PK, the db will have to work harder to perform the sort?

Why not use an ImageButton control?

Create a Keybinding

To auto indent on Sublime text 3 with a key bind try going to

Preferences > Key Bindings - users

And adding this code between the square brackets

{"keys": ["alt+shift+f"], "command": "reindent", "args": {"single_line": false}}

it sets shift + alt + f to be your full page auto indent.

Source here

Note: if this doesn't work correctly then you should convert your indentation to tabs. Also comments in your code can push your code to the wrong indentation level and may have to be moved manually.

James' answer is correct, of course, but I should remind you that the whole ASMX thing is, if not obsolete, at least not the current method. I strongly suggest that you look into WCF, if only to avoid learning things you will need to forget.

Error 'Duplicate entry '338620-7' for key 2' on query. Default database

As the other have mentioned, the load event does not bubble. Instead you can manually trigger a load-like event with a custom event:

$('#item').on('namespace/onload', handleOnload).trigger('namespace/onload')

If your element is already listening to a change event:

$('#item').on('change', handleChange).trigger('change')

I find this works well. Though, I stick to custom events to be more explicit and avoid side effects.

Note if you are using typings do the following:

rm -r typings
typings install

If your doing the angular 2 tutorial use this:

rm -r typings
npm run postinstall
npm start

if the postinstall command dosen't work, try installing typings globally like so:

npm install -g typings

you can also try the following as opposed to postinstall:

typings install

and you should have this issue fixed!

Actually this is the path and you should mention a valid path for this to work. If your data directory is in current directory then instead of my-data you should mention ./my-data, otherwise it will give you that error in mysql and mariadb also.

volumes:
 ./my-data:/var/lib/mysql

I find it very useful to append both stdout and stderr to a log file. I was glad to see a solution by alfonx with exec > >(tee -a), because I was wondering how to accomplish this using exec. I came across a creative solution using here-doc syntax and .: https://unix.stackexchange.com/questions/80707/how-to-output-text-to-both-screen-and-file-inside-a-shell-script

I discovered that in zsh, the here-doc solution can be modified using the "multios" construct to copy output to both stdout/stderr and the log file:

#!/bin/zsh
LOG=$0.log
# 8 is an arbitrary number;
# multiple redirects for the same file descriptor 
# triggers "multios"
. 8<<\EOF /dev/fd/8 2>&2 >&1 2>>$LOG >>$LOG
# some commands
date >&2
set -x
echo hi
echo bye
EOF
echo not logged

It is not as readable as the exec solution but it has the advantage of allowing you to log just part of the script. Of course, if you omit the EOF then the whole script is executed with logging. I'm not sure how zsh implements multios, but it may have less overhead than tee. Unfortunately it seems that one cannot use multios with exec.

Assuming they are in a file or array just do the replace as a batch (i.e. on all at once):

$input = str_replace(array('.', ','), array('', '.'), $input); 

and then process the numbers from there taking full advantage of PHP's loosely typed nature.

For Swift 4;

let uuid = NSUUID().uuidString.lowercased()

You have indented part of your code in settings.py:

# Uncomment the next line to enable the admin:
     'django.contrib.admin',
    # Uncomment the next line to enable admin documentation:
    #'django.contrib.admindocs',
     'tinymce',
     'sorl.thumbnail',
     'south',
     'django_facebook',
     'djcelery',
     'devserver',
     'main',

Therefore, it is giving you an error.

List last updated on December 1, 2020:

As of November 30, 2020, AWS now has EC2 Mac instances:

• https://aws.amazon.com/ec2/instance-types/mac/

We previously used and had good experiences with:

• https://MacStadium.com/

Here are some other sites that I am aware of:

• https://flow.swiss/
• https://hostmyapple.com/ (We used them a long time ago, before MacStadium)
• https://macincloud.com/
• https://macminivault.com/
• https://macweb.com/
• https://virtualmacosx.com/
• https://xcloud.me/
• https://zeromac.com/
• http://www.cloud4mac.com/ 404 as of July, 2014
• https://www.macminicloud.net/ (Redirects to macweb.com)
• https://xcloud.me/ (Redirects to flow.swiss)

When we were with MacStadium, we loved them. We had great connectivity/uptime. When I've needed hands-on support to plug in a Time Machine backup, they've been great. They performed a seamless upgrade to better hardware for us over one weekend (when we could afford a bit of downtime), and that went off without a hitch. Highly recommended. (Not affiliated - just happy).

In April of 2020, we stopped using MacStadium, simply because we no longer needed a Mac server. If I need another Mac host, I would be happy to go back to them.

Since AmazonDynamoDBClient(credentials) is deprecated i use this.

init {
        val cp= AWSStaticCredentialsProvider(BasicAWSCredentials(ACCESS_KEY, SECRET_KEY))
        val client = AmazonDynamoDBClientBuilder.standard().withCredentials(cp).withRegion(Regions.US_EAST_1).build()
        dynamoDB = DynamoDB(client)
    }

You have to indent the docstring after the function definition there (line 3, 4):

def print_lol(the_list):
"""this doesn't works"""
    print 'Ain't happening'

Indented:

def print_lol(the_list):
    """this works!"""
    print 'Aaaand it's happening'

Or you can use # to comment instead:

def print_lol(the_list):
#this works, too!
    print 'Hohoho'

Also, you can see PEP 257 about docstrings.

Hope this helps!

You can also print the path of MSBuild.exe to the command line:

reg.exe query "HKLM\SOFTWARE\Microsoft\MSBuild\ToolsVersions\4.0" /v MSBuildToolsPath

This is what you wanna do:

var oldSrc = 'http://example.com/smith.gif';
var newSrc = 'http://example.com/johnson.gif';
$('img[src="' + oldSrc + '"]').attr('src', newSrc);

If both application have the same signature (meaning that both APPS are yours and signed with the same key), you can call your other app activity as follows:

Intent LaunchIntent = getActivity().getPackageManager().getLaunchIntentForPackage(CALC_PACKAGE_NAME);
startActivity(LaunchIntent);

Hope it helps.

I think it is totally independent. Just install them, then you have the commands e.g. /usr/bin/python2.5 and /usr/bin/python2.6. Link /usr/bin/python to the one you want to use as default.

All the libraries are in separate folders (named after the version) anyway.

If you want to compile the versions manually, this is from the readme file of the Python source code:

Installing multiple versions

On Unix and Mac systems if you intend to install multiple versions of Python using the same installation prefix (--prefix argument to the configure script) you must take care that your primary python executable is not overwritten by the installation of a different version. All files and directories installed using "make altinstall" contain the major and minor version and can thus live side-by-side. "make install" also creates ${prefix}/bin/python3 which refers to ${prefix}/bin/pythonX.Y. If you intend to install multiple versions using the same prefix you must decide which version (if any) is your "primary" version. Install that version using "make install". Install all other versions using "make altinstall".

For example, if you want to install Python 2.5, 2.6 and 3.0 with 2.6 being the primary version, you would execute "make install" in your 2.6 build directory and "make altinstall" in the others.

I would suggest the following:

String[] parsedInput = str.split("\n"); String firstName = parsedInput[0].split(": ")[1]; String lastName = parsedInput[1].split(": ")[1]; myMap.put(firstName,lastName); 

if a device has an SD card, you use:

Environment.getExternalStorageState() 

if you don't have an SD card, you use:

Environment.getDataDirectory()

if there is no SD card, you can create your own directory on the device locally.

    //if there is no SD card, create new directory objects to make directory on device
        if (Environment.getExternalStorageState() == null) {
                        //create new file directory object
            directory = new File(Environment.getDataDirectory()
                    + "/RobotiumTestLog/");
            photoDirectory = new File(Environment.getDataDirectory()
                    + "/Robotium-Screenshots/");
            /*
             * this checks to see if there are any previous test photo files
             * if there are any photos, they are deleted for the sake of
             * memory
             */
            if (photoDirectory.exists()) {
                File[] dirFiles = photoDirectory.listFiles();
                if (dirFiles.length != 0) {
                    for (int ii = 0; ii <= dirFiles.length; ii++) {
                        dirFiles[ii].delete();
                    }
                }
            }
            // if no directory exists, create new directory
            if (!directory.exists()) {
                directory.mkdir();
            }

            // if phone DOES have sd card
        } else if (Environment.getExternalStorageState() != null) {
            // search for directory on SD card
            directory = new File(Environment.getExternalStorageDirectory()
                    + "/RobotiumTestLog/");
            photoDirectory = new File(
                    Environment.getExternalStorageDirectory()
                            + "/Robotium-Screenshots/");
            if (photoDirectory.exists()) {
                File[] dirFiles = photoDirectory.listFiles();
                if (dirFiles.length > 0) {
                    for (int ii = 0; ii < dirFiles.length; ii++) {
                        dirFiles[ii].delete();
                    }
                    dirFiles = null;
                }
            }
            // if no directory exists, create new directory to store test
            // results
            if (!directory.exists()) {
                directory.mkdir();
            }
        }// end of SD card checking

add permissions on your manifest.xml

Happy coding..

Using " is the way to do it. I tried your second code snippet, and it works in both Firefox and Internet Explorer.

The reason i could not delete some of the users via 'drop' statement was that there is a bug in Mysql http://bugs.mysql.com/bug.php?id=62255 with hostname containing upper case letters. The solution was running following query:

I am still trying to figure the other issue where the root user with all permissions are unable to grant privileges to new user for particular database

Here's a way:

                var value = $('input[type="hidden"]')[0].value;
                alert(value.split(/\?/)[1]);
            });
        </script>

What you actually created with:

MyType[] list = []

Was fixed size array (not list) with size of 0. You can create fixed size array of size for example 4 with:

MyType[] array = new MyType[4]

But there's no add method of course.

If you create list with def it's something like creating this instance with Object (You can read more about def here). And [] creates empty ArrayList in this case.

So using def list = [] you can then append new items with add() method of ArrayList

list.add(new MyType())

Or more groovy way with overloaded left shift operator:

list << new MyType() 

This works:

$('img').bind('contextmenu', function(e) {
    return false;
}); 

Or for newer jQuery:

$('#nearestStaticContainer').on('contextmenu', 'img', function(e){ 
  return false; 
});

jsFiddle example

A shorter answer: flatten the array of data ordered by columns then

//$array = array( '1','2','3','4','5', '1','2','3','4','5');
$arCount = count($array);
$rCount = ($arCount  ? $arCount - 1 : 0);
$criteria = sprintf("(?,?,?,?,?)%s", str_repeat(",(?,?,?,?,?)", $rCount));
$sql = "INSERT INTO table(c1,c2,c3,c4,c5) VALUES$criteria";

When inserting a 1,000 or so records you don't want to have to loop through every record to insert them when all you need is a count of the values.

all you need is to

1. open terminal type

   opt/lampp/lampp start

to start it and then

2. sudo chmod 755 /opt/lampp/phpmyadmin/config.inc.php

then visit in your browser

localhost/phpmyadmin

it will work fine.

JEP 354: Switch Expressions (Preview) in JDK-13 and JEP 361: Switch Expressions (Standard) in JDK-14 will extend the switch statement so it can be used as an expression.

Now you can:

• directly assign variable from switch expression,
• use new form of switch label (case L ->):

  The code to the right of a "case L ->" switch label is restricted to be an expression, a block, or (for convenience) a throw statement.

• use multiple constants per case, separated by commas,
• and also there are no more value breaks:

  To yield a value from a switch expression, the break with value statement is dropped in favor of a yield statement.

So the demo from the answers (1, 2) might look like this:

  public static void main(String[] args) {
    switch (args[0]) {
      case "Monday", "Tuesday", "Wednesday" ->  System.out.println("boring");
      case "Thursday" -> System.out.println("getting better");
      case "Friday", "Saturday", "Sunday" -> System.out.println("much better");
    }

you can create your own custom event by using diagnostics.Event log class. Open a windows application and on a button click do the following code.

System.Diagnostics.EventLog.CreateEventSource("ApplicationName", "MyNewLog");

"MyNewLog" means the name you want to give to your log in event viewer.

var numbers = sNumbers.Split(',').Select(Int32.Parse).ToList();

I believe there is still no ideal solution that would correctly preserve all whitespace characters and is fast enough, so I'll post my answer. Using ${foo:$i:1} works, but is very slow, which is especially noticeable with large strings, as I will show below.

My idea is an expansion of a method proposed by Six, which involves read -n1, with some changes to keep all characters and work correctly for any string:

while IFS='' read -r -d '' -n 1 char; do
        # do something with $char
done < <(printf %s "$string")

How it works:

• IFS='' - Redefining internal field separator to empty string prevents stripping of spaces and tabs. Doing it on a same line as read means that it will not affect other shell commands.
• -r - Means "raw", which prevents read from treating \ at the end of the line as a special line concatenation character.
• -d '' - Passing empty string as a delimiter prevents read from stripping newline characters. Actually means that null byte is used as a delimiter. -d '' is equal to -d $'\0'.
• -n 1 - Means that one character at a time will be read.
• printf %s "$string" - Using printf instead of echo -n is safer, because echo treats -n and -e as options. If you pass "-e" as a string, echo will not print anything.
• < <(...) - Passing string to the loop using process substitution. If you use here-strings instead (done <<< "$string"), an extra newline character is appended at the end. Also, passing string through a pipe (printf %s "$string" | while ...) would make the loop run in a subshell, which means all variable operations are local within the loop.

Now, let's test the performance with a huge string. I used the following file as a source:
https://www.kernel.org/doc/Documentation/kbuild/makefiles.txt
The following script was called through time command:

#!/bin/bash

# Saving contents of the file into a variable named `string'.
# This is for test purposes only. In real code, you should use
# `done < "filename"' construct if you wish to read from a file.
# Using `string="$(cat makefiles.txt)"' would strip trailing newlines.
IFS='' read -r -d '' string < makefiles.txt

while IFS='' read -r -d '' -n 1 char; do
        # remake the string by adding one character at a time
        new_string+="$char"
done < <(printf %s "$string")

# confirm that new string is identical to the original
diff -u makefiles.txt <(printf %s "$new_string")

And the result is:

$ time ./test.sh

real    0m1.161s
user    0m1.036s
sys     0m0.116s

As we can see, it is quite fast.
Next, I replaced the loop with one that uses parameter expansion:

for (( i=0 ; i<${#string}; i++ )); do
    new_string+="${string:$i:1}"
done

The output shows exactly how bad the performance loss is:

$ time ./test.sh

real    2m38.540s
user    2m34.916s
sys     0m3.576s

The exact numbers may very on different systems, but the overall picture should be similar.

You can run easy_install to install python packages in your home directory even without root access. There's a standard way to do this using site.USER_BASE which defaults to something like $HOME/.local or $HOME/Library/Python/2.7/bin and is included by default on the PYTHONPATH

To do this, create a .pydistutils.cfg in your home directory:

cat > $HOME/.pydistutils.cfg <<EOF
[install]
user=1
EOF

Now you can run easy_install without root privileges:

easy_install boto

Alternatively, this also lets you run pip without root access:

pip install boto

This works for me.

If You try to connect by pysftp to "normal" FTP You have to set hostkey to None.

import pysftp

cnopts = pysftp.CnOpts()
cnopts.hostkeys = None 
with pysftp.Connection(host='****',username='****',password='***',port=22,cnopts=cnopts) as sftp:
    print('DO SOMETHING')

The best place to find answers to general (and somewhat easy questions) such as this is to read up on PHP docs. Specifically in your case you can read more on objects. You can store stdObject and instantiated objects within an array. In fact, there is a process known as 'hydration' which populates the member variables of an object with values from a database row, then the object is stored in an array (possibly with other objects) and returned to the calling code for access.

-- Edit --

class Car
{
    public $color;
    public $type;
}

$myCar = new Car();
$myCar->color = 'red';
$myCar->type = 'sedan';

$yourCar = new Car();
$yourCar->color = 'blue';
$yourCar->type = 'suv';

$cars = array($myCar, $yourCar);

foreach ($cars as $car) {
    echo 'This car is a ' . $car->color . ' ' . $car->type . "\n";
}

This little function I made has always worked for me :)

String.prototype.deleteWord = function (searchTerm) {
    var str = this;
    var n = str.search(searchTerm);
    while (str.search(searchTerm) > -1) {
        n = str.search(searchTerm);
        str = str.substring(0, n) + str.substring(n + searchTerm.length, str.length);
    }
    return str;
}

// Use it like this:
var string = "text is the cool!!";
string.deleteWord('the'); // Returns text is cool!!

I know it is not the best, but It has always worked for me :)

You almost always want autocrlf=input unless you really know what you are doing.

Some additional context below:

It should be either core.autocrlf=true if you like DOS ending or core.autocrlf=input if you prefer unix-newlines. In both cases, your Git repository will have only LF, which is the Right Thing. The only argument for core.autocrlf=false was that automatic heuristic may incorrectly detect some binary as text and then your tile will be corrupted. So, core.safecrlf option was introduced to warn a user if a irreversable change happens. In fact, there are two possibilities of irreversable changes -- mixed line-ending in text file, in this normalization is desirable, so this warning can be ignored, or (very unlikely) that Git incorrectly detected your binary file as text. Then you need to use attributes to tell Git that this file is binary.

The above paragraph was originally pulled from a thread on gmane.org, but it has since gone down.

In case the error appears when upgrading from Laravel 6 to Laravel 7, the command composer require laravel/ui "^2.0" solves the problem (see https://laravel.com/docs/7.x/upgrade#authentication -scaffolding)

Try this one.. It is working... Here JSBIN

table tbody { height:300px; overflow-y:scroll; display:block; }
table thead { display:block; }

You could implement a JavaScript block which contains a function with your needs.

<div style="position: absolute; left: 10px; top: 40px;"> 
    <img src="logg.png" width="114" height="38" onclick="DoSomething();" />
</div>

I was not even concentrating, here is how to do it

$DOCDIR = [Environment]::GetFolderPath("MyDocuments")
$TARGETDIR = '$DOCDIR\MatchedLog'
if(!(Test-Path -Path $TARGETDIR )){
    New-Item -ItemType directory -Path $TARGETDIR
}

Not an answer to your question (which others have answered), but if you want to have some edit functionality of an uploaded file field, what you probably want to do is:

• show the current value of this field by just printing the filename or URL, a clickable link to download it, or if it's an image: just show it, possibly as thumbnail
• the <input> tag to upload a new file
• a checkbox that, when checked, deletes the currently uploaded file. note that there's no way to upload an 'empty' file, so you need something like this to clear out the field's value

I am running mysql on a computer on a local network. MySQL Workbench could connect to that server, but not my c# code. I solved my issue by disconnecting from a vpn client that was running.

Jin Yong - IE has an issue with polluting the global scope with object references to any DOM elements with a "name" or "id" attribute set on the "initial" page load.

Thus you may have issues due to your variable name.

Try this and see if it works.

var someOtherName="abc";
//  ^^^^^^^^^^^^^
document.getElementById('msg').value = someOtherName;
document.getElementById('sp_100').checked = true;

There is a chance (in your original code) that IE attempts to set the value of the input to a reference to that actual element (ignores the error) but leaves you with no new value.

Keep in mind that in IE6/IE7 case doesn't matter for naming objects. IE believes that "foo" "Foo" and "FOO" are all the same object.

netstat -ano|find ":port_no" will give you the list.
a: Displays all connections and listening ports.
n: Displays addresses and port numbers in numerical form.
o: Displays the owning process ID associated with each connection .

example : netstat -ano | find ":1900" This gives you the result like this.

Yes typically, a session will end after 20 minutes in PHP.

For Asp.Net MVC

@Html.ListBox("parameterName", ViewBag.ParameterValueList as MultiSelectList, 
 new { 
 @class = "chosen-select form-control"
 }) 

or

  @Html.ListBoxFor(model => model.parameterName,
  ViewBag.ParameterValueList as MultiSelectList,
   new{
       data_placeholder = "Select Options ",
       @class = "chosen-select form-control"
   })

We can try a simpler one as follows:

docker image inspect image_id

This worked in Docker version:

DockerVersion": "18.05.0-ce"

You can get good Time Series graphs in Excel, the way you want, but you have to work with a few quirks.

1. Be sure to select "Scatter Graph" (with a line option). This is needed if you have non-uniform time stamps, and will scale the X-axis accordingly.

2. In your data, you need to add a column with the mid-point. Here's what I did with your sample data. (This trick ensures that the data gets plotted at the mid-point, like you desire.)

3. You can format the x-axis options with this menu. (Chart->Design->Layout)

4. Select "Axes" and go to Primary Horizontal Axis, and then select "More Primary Horizontal Axis Options"

5. Set up the options you wish. (Fix the starting and ending points.)

6. And you will get a graph such as the one below.

You can then tweak many of the options, label the axes better etc, but this should get you started.

Hope this helps you move forward.

According to the documentation:

$validator = Validator::make($request->all(), [
    'file' => 'max:500000',
]);

The value is in kilobytes. I.e. max:10240 = max 10 MB.

A global function that can be reused:

function getCheckedGroupBoxes(groupName) {

    var checkedAry= [];
    $.each($("input[name='" + groupName + "']:checked"), function () {
        checkedAry.push($(this).attr("id"));
    });

     return checkedAry;

}

where the groupName is the name of the group of the checkboxes, in you example :'options[]'

I had the same problem building VS 2013 Project with Visual Studio 2017 IDE. The solution was to set the right "Platformtoolset v120 (Visual Studio 2013). Therefor there must be the Windows SDK 8.1 installed. If you want to use Platformtoolset v141 (Visual Studio 2017) there must be Windows SDK 10. The Platformtoolset can be chosen inside the properties dialog of the project: General -> Platformtoolset

update YourTable
    set YourColumn = replace(YourColumn, '@domain2', '@domain1')
    where charindex('@domain2', YourColumn) <> 0

Okay, I am now connecting without the semaphore timeout problem.

If anyone reading ever encounters the same thing, I hope that this procedure works for you; but no promises; hey, it's windows.

In my case this was Windows 7

I got a little hint from This page on eHow; not sure if that might help anyone or not.

So anyway, this was the simple twenty three step procedure that worked for me

• Click on start button

• Choose Control Panel

• From Control Panel, choose Device Manger

• From Device Manager, choose Universal Serial Bus Controllers

• From Universal Serial Bus Controllers, click the little sideways triangle

• I cannot predict what you'll see on your computer, but on mine I get a long drop-down list

• Begin the investigation to figure out which one of these members of this list is the culprit...

  • On each member of the drop-down list, right-click on the name

  • A list will open, choose Properties

  • Guesswork time: using the various tabs near the top of the resulting window which opens, make a guess if this is the USB adapter driver which is choking your stuff with semaphore timeouts

• Once you have made the proper guess, then close the USB Root Hub Properties window (but leave the Device Manager window open).

• Physically disonnect anything and everything from that USB hub.

• Unplug it.

• Return your mouse pointer to that USB Root Hub in the list which you identified earlier.

• Right click again

• Choose Uninstall

• Let Windows do its thing

• Wait a little while

• Power Down the whole computer if you have the time; some say this is required. I think I got away without it.

• Plug the USB hub back into a USB connector on the PC

• If the list in the device manager blinks and does a few flash-bulbs, it's okay.

• Plug the BlueTooth connector back into the USB hub

• Let windows do its thing some more

• Within two minutes, I had a working COM port again, no semaphore timeouts.

Hope it works for anyone else who may be having a similar problem.

Just to shed some light on this.

After I deleted my p12 certificate from Keychain. I re-downloaded my own certificate from Apple developer portal.

I was only able to download the certificate. But to sign you need the private key as well. So you either:

• export both private key and certificate from Keychain to get it.

• Upload a Certificate Signing Request and generate new certificates

That certificate by itself has no value for signing purposes. My guess is that the private key is created by keychain the moment you 'request a certificate from a certificate authority' but isn't shown to you until you add its tying certificate.

var top = $('html').offset().top;

should do it.

edit: this is the negative of $(document).scrollTop()

First composer requires doctrine/dbal, then:

According to the jQuery Plugin Authoring page (http://docs.jquery.com/Plugins/Authoring), it's best not to muddy up the jQuery and jQuery.fn namespaces. They suggest this method:

(function( $ ){

    var methods = {
        init : function(options) {

        },
        show : function( ) {    },// IS
        hide : function( ) {  },// GOOD
        update : function( content ) {  }// !!!
    };

    $.fn.tooltip = function(methodOrOptions) {
        if ( methods[methodOrOptions] ) {
            return methods[ methodOrOptions ].apply( this, Array.prototype.slice.call( arguments, 1 ));
        } else if ( typeof methodOrOptions === 'object' || ! methodOrOptions ) {
            // Default to "init"
            return methods.init.apply( this, arguments );
        } else {
            $.error( 'Method ' +  methodOrOptions + ' does not exist on jQuery.tooltip' );
        }    
    };


})( jQuery );

Basically you store your functions in an array (scoped to the wrapping function) and check for an entry if the parameter passed is a string, reverting to a default method ("init" here) if the parameter is an object (or null).

Then you can call the methods like so...

$('div').tooltip(); // calls the init method
$('div').tooltip({  // calls the init method
  foo : 'bar'
});
$('div').tooltip('hide'); // calls the hide method
$('div').tooltip('update', 'This is the new tooltip content!'); // calls the update method

Javascripts "arguments" variable is an array of all the arguments passed so it works with arbitrary lengths of function parameters.

The root of it all is to make sure that the requests are coming from the actual users of the site. A csrf token is generated for the forms and Must be tied to the user's sessions. It is used to send requests to the server, in which the token validates them. This is one way of protecting against csrf, another would be checking the referrer header.

If you have date in DateTime variable then its a DateTime object and doesn't contain any format. Formatted date are expressed as string when you call DateTime.ToString method and provide format in it.

Lets say you have two DateTime variable, you can use the compare method for comparision,

DateTime date1 = new DateTime(2009, 8, 1, 0, 0, 0);
DateTime date2 = new DateTime(2009, 8, 2, 0, 0, 0);
int result = DateTime.Compare(date1, date2);
string relationship;

if (result < 0)
   relationship = "is earlier than";
else if (result == 0)
   relationship = "is the same time as";         
else
   relationship = "is later than";
