If multiple clock are generated with different frequencies, then clock generation can be simplified if a procedure is called as concurrent procedure call. The time resolution issue, mentioned by Martin Thompson, may be mitigated a little by using different high and low time in the procedure. The test bench with procedure for clock generation is:

library ieee;
use ieee.std_logic_1164.all;

entity tb is
end entity;

architecture sim of tb is

  -- Procedure for clock generation
  procedure clk_gen(signal clk : out std_logic; constant FREQ : real) is
    constant PERIOD    : time := 1 sec / FREQ;        -- Full period
    constant HIGH_TIME : time := PERIOD / 2;          -- High time
    constant LOW_TIME  : time := PERIOD - HIGH_TIME;  -- Low time; always >= HIGH_TIME
  begin
    -- Check the arguments
    assert (HIGH_TIME /= 0 fs) report "clk_plain: High time is zero; time resolution to large for frequency" severity FAILURE;
    -- Generate a clock cycle
    loop
      clk <= '1';
      wait for HIGH_TIME;
      clk <= '0';
      wait for LOW_TIME;
    end loop;
  end procedure;

  -- Clock frequency and signal
  signal clk_166 : std_logic;
  signal clk_125 : std_logic;

begin

  -- Clock generation with concurrent procedure call
  clk_gen(clk_166, 166.667E6);  -- 166.667 MHz clock
  clk_gen(clk_125, 125.000E6);  -- 125.000 MHz clock

  -- Time resolution show
  assert FALSE report "Time resolution: " & time'image(time'succ(0 fs)) severity NOTE;

end architecture;

The time resolution is printed on the terminal for information, using the concurrent assert last in the test bench.

If the clk_gen procedure is placed in a separate package, then reuse from test bench to test bench becomes straight forward.

Waveform for clocks are shown in figure below.

An more advanced clock generator can also be created in the procedure, which can adjust the period over time to match the requested frequency despite the limitation by time resolution. This is shown here:

-- Advanced procedure for clock generation, with period adjust to match frequency over time, and run control by signal
procedure clk_gen(signal clk : out std_logic; constant FREQ : real; PHASE : time := 0 fs; signal run : std_logic) is
  constant HIGH_TIME   : time := 0.5 sec / FREQ;  -- High time as fixed value
  variable low_time_v  : time;                    -- Low time calculated per cycle; always >= HIGH_TIME
  variable cycles_v    : real := 0.0;             -- Number of cycles
  variable freq_time_v : time := 0 fs;            -- Time used for generation of cycles
begin
  -- Check the arguments
  assert (HIGH_TIME /= 0 fs) report "clk_gen: High time is zero; time resolution to large for frequency" severity FAILURE;
  -- Initial phase shift
  clk <= '0';
  wait for PHASE;
  -- Generate cycles
  loop
    -- Only high pulse if run is '1' or 'H'
    if (run = '1') or (run = 'H') then
      clk <= run;
    end if;
    wait for HIGH_TIME;
    -- Low part of cycle
    clk <= '0';
    low_time_v := 1 sec * ((cycles_v + 1.0) / FREQ) - freq_time_v - HIGH_TIME;  -- + 1.0 for cycle after current
    wait for low_time_v;
    -- Cycle counter and time passed update
    cycles_v := cycles_v + 1.0;
    freq_time_v := freq_time_v + HIGH_TIME + low_time_v;
  end loop;
end procedure;

Again reuse through a package will be nice.

A 24 hour clock:

setInterval(function(){

        var currentTime = new Date();
        var hours = currentTime.getHours();
        var minutes = currentTime.getMinutes();
        var seconds = currentTime.getSeconds();

        // Add leading zeros
        minutes = (minutes < 10 ? "0" : "") + minutes;
        seconds = (seconds < 10 ? "0" : "") + seconds;
        hours = (hours < 10 ? "0" : "") + hours;

        // Compose the string for display
        var currentTimeString = hours + ":" + minutes + ":" + seconds;
        $(".clock").html(currentTimeString);

},1000);

// 24 hour clock  _x000D_
setInterval(function() {_x000D_
_x000D_
  var currentTime = new Date();_x000D_
  var hours = currentTime.getHours();_x000D_
  var minutes = currentTime.getMinutes();_x000D_
  var seconds = currentTime.getSeconds();_x000D_
_x000D_
  // Add leading zeros_x000D_
  hours = (hours < 10 ? "0" : "") + hours;_x000D_
  minutes = (minutes < 10 ? "0" : "") + minutes;_x000D_
  seconds = (seconds < 10 ? "0" : "") + seconds;_x000D_
_x000D_
  // Compose the string for display_x000D_
  var currentTimeString = hours + ":" + minutes + ":" + seconds;_x000D_
  $(".clock").html(currentTimeString);_x000D_
_x000D_
}, 1000);

<div class="clock"></div>

In the POSIX standard clock has its return value defined in terms of the CLOCKS_PER_SEC symbol and an implementation is free to define this in any convenient fashion. Under Linux, I have had good luck with the times() function.

clock() returns the number of clock ticks since your program started. There is a related constant, CLOCKS_PER_SEC, which tells you how many clock ticks occur in one second. Thus, you can test any operation like this:

clock_t startTime = clock();
doSomeOperation();
clock_t endTime = clock();
clock_t clockTicksTaken = endTime - startTime;
double timeInSeconds = clockTicksTaken / (double) CLOCKS_PER_SEC;

Simply go to the directory where the troubling file is, type touch * without quotes in the console, and you should be good.

This code snippet can be used for displaying time in seconds,milliseconds and microseconds:

#include <sys/time.h>

struct timeval start, stop;
double secs = 0;

gettimeofday(&start, NULL);

// Do stuff  here

gettimeofday(&stop, NULL);
secs = (double)(stop.tv_usec - start.tv_usec) / 1000000 + (double)(stop.tv_sec - start.tv_sec);
printf("time taken %f\n",secs);

You can also use TimerTask for that.

Here is an method

private void setTimerTask() {
    long delay = 3000;
    long periodToRepeat = 60 * 1000; /* 1 mint */
    Timer timer = new Timer();
    timer.schedule(new TimerTask() {
        @Override
        public void run() {
            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                 //   do your stuff here.
                }
            });
        }
    }, 3000, 3000);
}

Maybe you have some duplicated Activities

Like this:

<activity android:name=".register.RegisterStepsActivity" />

....

<activity android:name=".register.RegisterStepsActivity" />

just comment one of them

First, I purchased the domain in GoDaddy, and when I clicked this link https://www.google.com/settings/security/lesssecureapps I didn't have the option, it show this message "The domain administrator manages these settings", so I go to the Admin Console https://admin.google.com/

There is this option

Then appears the option that I needed in

public static function recursiveDelete($dir)
{
    foreach (new \DirectoryIterator($dir) as $fileInfo) {
        if (!$fileInfo->isDot()) {
            if ($fileInfo->isDir()) {
                recursiveDelete($fileInfo->getPathname());
            } else {
                unlink($fileInfo->getPathname());
            }
        }
    }
    rmdir($dir);
}

Maybe not very elegant, but it does the job:

exec(open("script.py").read())

If you are using at least Java 8 you can use method runAsync from class CompletableFuture

CompletableFuture.runAsync(() -> {...});

If you need to return a result use supplyAsync instead

CompletableFuture.supplyAsync(() -> 1);

Supplemental Answer

Here are some visual supplements to the other answers. My full answer is here.

The dispatchTouchEvent() method of a ViewGroup uses onInterceptTouchEvent() to choose whether it should immediately handle the touch event (with onTouchEvent()) or continue notifying the dispatchTouchEvent() methods of its children.

Best way to apply event on dynamically generated content by using delegation.

$(document).on("eventname","selector",function(){
    // code goes here
});

so your code is like this now

$(document).on("click",".test",function(){
    // code goes here
});

Simple, just use .set_color

>>> barlist=plt.bar([1,2,3,4], [1,2,3,4])
>>> barlist[0].set_color('r')
>>> plt.show()

For your new question, not much harder either, just need to find the bar from your axis, an example:

>>> f=plt.figure()
>>> ax=f.add_subplot(1,1,1)
>>> ax.bar([1,2,3,4], [1,2,3,4])
<Container object of 4 artists>
>>> ax.get_children()
[<matplotlib.axis.XAxis object at 0x6529850>, 
 <matplotlib.axis.YAxis object at 0x78460d0>,  
 <matplotlib.patches.Rectangle object at 0x733cc50>, 
 <matplotlib.patches.Rectangle object at 0x733cdd0>, 
 <matplotlib.patches.Rectangle object at 0x777f290>, 
 <matplotlib.patches.Rectangle object at 0x777f710>, 
 <matplotlib.text.Text object at 0x7836450>, 
 <matplotlib.patches.Rectangle object at 0x7836390>, 
 <matplotlib.spines.Spine object at 0x6529950>, 
 <matplotlib.spines.Spine object at 0x69aef50>,
 <matplotlib.spines.Spine object at 0x69ae310>, 
 <matplotlib.spines.Spine object at 0x69aea50>]
>>> ax.get_children()[2].set_color('r') 
 #You can also try to locate the first patches.Rectangle object 
 #instead of direct calling the index.

If you have a complex plot and want to identify the bars first, add those:

>>> import matplotlib
>>> childrenLS=ax.get_children()
>>> barlist=filter(lambda x: isinstance(x, matplotlib.patches.Rectangle), childrenLS)
[<matplotlib.patches.Rectangle object at 0x3103650>, 
 <matplotlib.patches.Rectangle object at 0x3103810>, 
 <matplotlib.patches.Rectangle object at 0x3129850>, 
 <matplotlib.patches.Rectangle object at 0x3129cd0>, 
 <matplotlib.patches.Rectangle object at 0x3112ad0>]

Unless I am misunderstanding you, this could be as easy as inspecting (F12) the icon on the page to reveal its .svg source file path, going to that path directly (Example), and then viewing the page source code with Control+u. Then just save that code.

I know it is an old thread, but recently I needed the same and found a neat way:

SELECT c.name FROM pragma_table_info('your_table_name') c;

This should work:

$(".hit").click(function(){    
   var value=$(this).closest('tr').children('td:first').text();
   alert(value);    
});

Explanation:

• .closest('tr') gets the nearest ancestor that is a <tr> element (so in this case the row where the <a> element is in).
• .children('td:first') gets all the children of this element, but with the :first selector we reduce it to the first <td> element.
• .text() gets the text inside the element

As you can see from the other answers, there is more than only one way to do this.

From the link above:

Several of these types can be modified using the keywords signed, unsigned, short, and long. When one of these type modifiers is used by itself, a data type of int is assumed

This means that you can assume the author is using ints.

Use empty (it checks both nullness and emptiness) and group the nested ternary expression by parentheses (EL is in certain implementations/versions namely somewhat problematic with nested ternary expressions). Thus, so:

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (obj.validationErrorMap.contains('key') ? 'highlight_field' : 'highlight_row')}"

If still in vain (I would then check JBoss EL configs), use the "normal" EL approach:

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (obj.validationErrorMap['key'] ne null ? 'highlight_field' : 'highlight_row')}"

Update: as per the comments, the Map turns out to actually be a List (please work on your naming conventions). To check if a List contains an item the "normal" EL way, use JSTL fn:contains (although not explicitly documented, it works for List as well).

styleClass="#{empty obj.validationErrorMap ? ' ' :  
 (fn:contains(obj.validationErrorMap, 'key') ? 'highlight_field' : 'highlight_row')}"

When working with pennies/integers. You will run into a problem with 115 (as in $1.15) and other numbers.

I had a function that would convert an Integer to a Float.

...
return float(115 * 0.01)

That worked most of the time but sometimes it would return something like 1.1500000000000001.

So I changed my function to return like this...

...
return float(format(115 * 0.01, '.2f'))

and that will return 1.15. Not '1.15' or 1.1500000000000001 (returns a float, not a string)

I'm mostly posting this so I can remember what I did in this scenario since this is the first result in google.

Extract the hour, look for a leading space, if found replace with a zero;

set hr=%time:~0,2%
if "%hr:~0,1%" equ " " set hr=0%hr:~1,1%
echo Archive_%date:~-4,4%%date:~-10,2%%date:~-7,2%_%hr%%time:~3,2%%time:~6,2%.zip

Add the following to package.json:

  "engines": {
    "node": ">=10.0.0",
    "npm": ">=6.0.0"
  },

Add the following to .npmrc (same directory as package.json):

engine-strict=true

Bit late but hopefully can still be useful to someone.

2 steps to adding items to a specific position in an ArrayList

1. add null items to a specific index in an ArrayList

2. Then set the positions as and when required.

       list = new ArrayList();//Initialise the ArrayList
   for (Integer i = 0; i < mItems.size(); i++) {
       list.add(i, null); //"Add" all positions to null
   }
      // "Set" Items
       list.set(position, SomeObject);
   

This way you don't have redundant items in the ArrayList i.e. if you were to add items such as,

list = new ArrayList(mItems.size());    
list.add(position, SomeObject);

This would not overwrite existing items in the position merely, shifting existing ones to the right by one - so you have an ArrayList with twice as many indicies.

You can look into HTML TIDY - http://uk.php.net/tidy

It can be installed as a PHP module and will (correctly, safely) strip whitespace and all other nastiness, whilst still outputting perfectly valid HTML / XHTML markup. It will also clean your code, which can be a great thing or a terrible thing, depending on how good you are at writing valid code in the first place ;-)

Additionally, you can gzip the output using the following code at the start of your file:

ob_start('ob_gzhandler');

FileStream fileStream = new FileStream("file.txt", FileMode.Open);
using (StreamReader reader = new StreamReader(fileStream))
{
    string line = reader.ReadLine();
}

Using the System.IO.FileStream and System.IO.StreamReader. You can use System.IO.BinaryReader or System.IO.BinaryWriter as well.

The supplied answers didn't work for me.

I had an empty repo on GitHub with only the LICENSE file and a single commit locally. What worked was:

$ git fetch
$ git merge --allow-unrelated-histories
Merge made by the 'recursive' strategy.
 LICENSE | 21 +++++++++++++++++++++
 1 file changed, 21 insertions(+)
 create mode 100644 LICENSE

Also before merge you may want to:

$ git branch --set-upstream-to origin/master
Branch 'master' set up to track remote branch 'master' from 'origin'.

Another one. Supports case and diacritic options.

Swift 3.0

struct MyString {
  static func contains(_ text: String, substring: String,
                       ignoreCase: Bool = true,
                       ignoreDiacritic: Bool = true) -> Bool {

    var options = NSString.CompareOptions()

    if ignoreCase { _ = options.insert(NSString.CompareOptions.caseInsensitive) }
    if ignoreDiacritic { _ = options.insert(NSString.CompareOptions.diacriticInsensitive) }

    return text.range(of: substring, options: options) != nil
  }
}

Usage

MyString.contains("Niels Bohr", substring: "Bohr") // true

iOS 9+

Case and diacritic insensitive function available since iOS 9.

if #available(iOS 9.0, *) {
  "Für Elise".localizedStandardContains("fur") // true
}

This is a work in progress, but this is what I don't understand:

ActivityManager activityManager = (ActivityManager) context.getSystemService(ACTIVITY_SERVICE);
MemoryInfo memoryInfo = new ActivityManager.MemoryInfo();
activityManager.getMemoryInfo(memoryInfo);

Log.i(TAG, " memoryInfo.availMem " + memoryInfo.availMem + "\n" );
Log.i(TAG, " memoryInfo.lowMemory " + memoryInfo.lowMemory + "\n" );
Log.i(TAG, " memoryInfo.threshold " + memoryInfo.threshold + "\n" );

List<RunningAppProcessInfo> runningAppProcesses = activityManager.getRunningAppProcesses();

Map<Integer, String> pidMap = new TreeMap<Integer, String>();
for (RunningAppProcessInfo runningAppProcessInfo : runningAppProcesses)
{
    pidMap.put(runningAppProcessInfo.pid, runningAppProcessInfo.processName);
}

Collection<Integer> keys = pidMap.keySet();

for(int key : keys)
{
    int pids[] = new int[1];
    pids[0] = key;
    android.os.Debug.MemoryInfo[] memoryInfoArray = activityManager.getProcessMemoryInfo(pids);
    for(android.os.Debug.MemoryInfo pidMemoryInfo: memoryInfoArray)
    {
        Log.i(TAG, String.format("** MEMINFO in pid %d [%s] **\n",pids[0],pidMap.get(pids[0])));
        Log.i(TAG, " pidMemoryInfo.getTotalPrivateDirty(): " + pidMemoryInfo.getTotalPrivateDirty() + "\n");
        Log.i(TAG, " pidMemoryInfo.getTotalPss(): " + pidMemoryInfo.getTotalPss() + "\n");
        Log.i(TAG, " pidMemoryInfo.getTotalSharedDirty(): " + pidMemoryInfo.getTotalSharedDirty() + "\n");
    }
}

Why isn't the PID mapped to the result in activityManager.getProcessMemoryInfo()? Clearly you want to make the resulting data meaningful, so why has Google made it so difficult to correlate the results? The current system doesn't even work well if I want to process the entire memory usage since the returned result is an array of android.os.Debug.MemoryInfo objects, but none of those objects actually tell you what pids they are associated with. If you simply pass in an array of all pids, you will have no way to understand the results. As I understand it's use, it makes it meaningless to pass in more than one pid at a time, and then if that's the case, why make it so that activityManager.getProcessMemoryInfo() only takes an int array?

I don't recall the exact syntax, but you may set the table column to be case insensitive. But be careful because then you won't be able to match based on case anymore and if you WANT 'cool' to not match 'CoOl' it will no longer be possible.

Should work:

.attr({
    target:"nw", 
    title:"Opens in a new window",
    "data-value":"internal link" // attributes which contain dash(-) should be covered in quotes.
});

Note:

" When setting multiple attributes, the quotes around attribute names are optional.

WARNING: When setting the 'class' attribute, you must always use quotes!

From the jQuery documentation (Sep 2016) for .attr:

Attempting to change the type attribute on an input or button element created via document.createElement() will throw an exception on Internet Explorer 8 or older.

Edit:
For future reference... To get a single attribute you would use

var strAttribute = $(".something").attr("title");

To set a single attribute you would use

$(".something").attr("title","Test");

To set multiple attributes you need to wrap everything in { ... }

$(".something").attr( { title:"Test", alt:"Test2" } );

Edit - If you're trying to get/set the 'checked' attribute from a checkbox...

You will need to use prop() as of jQuery 1.6+

the .prop() method provides a way to explicitly retrieve property values, while .attr() retrieves attributes.

...the most important concept to remember about the checked attribute is that it does not correspond to the checked property. The attribute actually corresponds to the defaultChecked property and should be used only to set the initial value of the checkbox. The checked attribute value does not change with the state of the checkbox, while the checked property does

So to get the checked status of a checkbox, you should use:

$('#checkbox1').prop('checked'); // Returns true/false

Or to set the checkbox as checked or unchecked you should use:

$('#checkbox1').prop('checked', true); // To check it
$('#checkbox1').prop('checked', false); // To uncheck it

from Mario Viviani blog one can use this solution from 17 Android Version:

https://plus.google.com/+MarioViviani/posts/fhuzYkji9zz

or

https://gist.github.com/Mariuxtheone/903c35b4927c0df18cf8

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

FROM TABLE A

The other way is

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

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

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

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

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

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

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

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

I have developed this functionality from one Blog. There are 2 ways you can send SMS.

1. Open native SMS composer
2. write your message and send from your Android application

This is the code of 1st method.

Main.xml

<?xml version="1.0" encoding="utf-8"?>  
    <RelativeLayout  
        android:id="@+id/relativeLayout1"  
        android:layout_width="fill_parent"  
        android:layout_height="fill_parent"  
        xmlns:android="http://schemas.android.com/apk/res/android">  

            <Button  
                android:id="@+id/btnSendSMS"  
               android:layout_height="wrap_content"  
               android:layout_width="wrap_content"  
               android:text="Send SMS"  
               android:layout_centerInParent="true"  
               android:onClick="sendSMS">  
           </Button>  
   </RelativeLayout>

Activity

public class SendSMSActivity extends Activity {  
     /** Called when the activity is first created. */  
     @Override  
     public void onCreate(Bundle savedInstanceState) {  
         super.onCreate(savedInstanceState);  
         setContentView(R.layout.main);  
      }  

     public void sendSMS(View v)  
     {  
         String number = "12346556";  // The number on which you want to send SMS  
         startActivity(new Intent(Intent.ACTION_VIEW, Uri.fromParts("sms", number, null)));  
     }  
    /* or 
     public void sendSMS(View v) 
      { 
     Uri uri = Uri.parse("smsto:12346556"); 
         Intent it = new Intent(Intent.ACTION_SENDTO, uri); 
         it.putExtra("sms_body", "Here you can set the SMS text to be sent"); 
         startActivity(it); 
      } */  
 }

NOTE:- In this method, you don’t require SEND_SMS permission inside the AndroidManifest.xml file.

For 2nd method refer to this BLOG. You will find a good explanation from here.

Hope this will help you...

I've found that there will be a new version of npm 5.7.1 with the new command npm ci, that will install from package-lock.json only

The new npm ci command installs from your lock-file ONLY. If your package.json and your lock-file are out of sync then it will report an error.

It works by throwing away your node_modules and recreating it from scratch.

Beyond guaranteeing you that you'll only get what is in your lock-file it's also much faster (2x-10x!) than npm install when you don't start with a node_modules.

As you may take from the name, we expect it to be a big boon to continuous integration environments. We also expect that folks who do production deploys from git tags will see major gains.

Hi nice answer by @Matti Virkkunen

public static List<int> AllIndexesOf(this string str, string value) {
    if (String.IsNullOrEmpty(value))
        throw new ArgumentException("the string to find may not be empty", "value");
    List<int> indexes = new List<int>();
    for (int index = 0;; index += value.Length) {
        index = str.IndexOf(value, index);
        if (index == -1)
            return indexes;
        indexes.Add(index);
        index--;
    }
}

But this covers tests cases like AOOAOOA where substring

Output 0 and 3

To add to Jefromi's answer, if you don't want to place a meaningless merge in the history of the source branch, you can create a temporary branch for the ours merge, then throw it away:

git checkout <source>
git checkout -b temp            # temporary branch for merge
git merge -s ours <target>      # create merge commit with contents of <source>
git checkout <target>           # fast forward <target> to merge commit
git merge temp                  # ...
git branch -d temp              # throw temporary branch away

That way the merge commit will only exist in the history of the target branch.

Alternatively, if you don't want to create a merge at all, you can simply grab the contents of source and use them for a new commit on target:

git checkout <source>                          # fill index with contents of <source>
git symbolic-ref HEAD <target>                 # tell git we're committing on <target>
git commit -m "Setting contents to <source>"   # make an ordinary commit with the contents of <source>

A sspi failed in xamarin android.

I found this solution; put this code before you hit on an HTTPS link

const SslProtocols _Tls12 = (SslProtocols)0x00000C00;
const SecurityProtocolType Tls12 = (SecurityProtocolType)_Tls12;
ServicePointManager.SecurityProtocol = Tls12;

I think a lot of times when you see this code, it's from people who are in the habit of event handlers for forms, buttons, inputs, and things of that sort.

Basically, when you have something like:

<form onsubmit="return callSomeFunction();"></form>

or

<a href="#" onclick="return callSomeFunction();"></a>`

and callSomeFunction() returns true, then the form or a will submit, otherwise it won't.

Other more obvious general purposes for returning true or false as a result of a function are because they are expected to return a boolean.

To display a phone number with (###) ###-#### format, you can create a new HtmlHelper.

Usage

@Html.DisplayForPhone(item.Phone)

HtmlHelper Extension

public static class HtmlHelperExtensions
{
    public static HtmlString DisplayForPhone(this HtmlHelper helper, string phone)
    {
        if (phone == null)
        {
            return new HtmlString(string.Empty);
        }
        string formatted = phone;
        if (phone.Length == 10)
        {
            formatted = $"({phone.Substring(0,3)}) {phone.Substring(3,3)}-{phone.Substring(6,4)}";
        }
        else if (phone.Length == 7)
        {
            formatted = $"{phone.Substring(0,3)}-{phone.Substring(3,4)}";
        }
        string s = $"<a href='tel:{phone}'>{formatted}</a>";
        return new HtmlString(s);
    }
}

I've developed my own MySQL escape method in Java (if useful for anyone).

See class code below.

Warning: wrong if NO_BACKSLASH_ESCAPES SQL mode is enabled.

private static final HashMap<String,String> sqlTokens;
private static Pattern sqlTokenPattern;

static
{           
    //MySQL escape sequences: http://dev.mysql.com/doc/refman/5.1/en/string-syntax.html
    String[][] search_regex_replacement = new String[][]
    {
                //search string     search regex        sql replacement regex
            {   "\u0000"    ,       "\\x00"     ,       "\\\\0"     },
            {   "'"         ,       "'"         ,       "\\\\'"     },
            {   "\""        ,       "\""        ,       "\\\\\""    },
            {   "\b"        ,       "\\x08"     ,       "\\\\b"     },
            {   "\n"        ,       "\\n"       ,       "\\\\n"     },
            {   "\r"        ,       "\\r"       ,       "\\\\r"     },
            {   "\t"        ,       "\\t"       ,       "\\\\t"     },
            {   "\u001A"    ,       "\\x1A"     ,       "\\\\Z"     },
            {   "\\"        ,       "\\\\"      ,       "\\\\\\\\"  }
    };

    sqlTokens = new HashMap<String,String>();
    String patternStr = "";
    for (String[] srr : search_regex_replacement)
    {
        sqlTokens.put(srr[0], srr[2]);
        patternStr += (patternStr.isEmpty() ? "" : "|") + srr[1];            
    }
    sqlTokenPattern = Pattern.compile('(' + patternStr + ')');
}


public static String escape(String s)
{
    Matcher matcher = sqlTokenPattern.matcher(s);
    StringBuffer sb = new StringBuffer();
    while(matcher.find())
    {
        matcher.appendReplacement(sb, sqlTokens.get(matcher.group(1)));
    }
    matcher.appendTail(sb);
    return sb.toString();
}

Absolutely valid.

    <form action="javascript:alert('Hello there, I am being submitted');">
        <button type="submit">
            Let's do it
        </button>
    </form>
    <!-- Tested in Firefox, Chrome, Edge and Safari -->

So for a short answer: yes, this is an option, and a nice one. It says "when submitted, please don't go anywhere, just run this script" - quite to the point.

A minor improvement

To let the event handler know which form we're dealing with, it would seem an obvious way to pass on the sender object:

    <form action="javascript:myFunction(this)">  <!-- should work, but it won't -->

But instead, it will give you undefined. You can't access it because javascript: links live in a separate scope. Therefore I'd suggest the following format, it's only 13 characters more and works like a charm:

    <form action="javascript:;" onsubmit="myFunction(this)">  <!-- now you have it! -->

... now you can access the sender form properly. (You can write a simple "#" as action, it's quite common - but it has a side effect of scrolling to the top when submitting.)

Again, I like this approach because it's effortless and self-explaining. No "return false", no jQuery/domReady, no heavy weapons. It just does what it seems to do. Surely other methods work too, but for me, this is The Way Of The Samurai.

A note on validation

Forms only get submitted if their onsubmit event handler returns something truthy, so you can easily run some preemptive checks:

    <form action="/something.php" onsubmit="return isMyFormValid(this)">

Now isMyFormValid will run first, and if it returns false, server won't even be bothered. Needless to say, you will have to validate on server side too, and that's the more important one. But for quick and convenient early detection this is fine.

I used ini_set('display_errors','off'); and it worked great.

Use eval() instead of ast.literal_eval() if the input is trusted (which it is in your case).

raw_data = userfile.read().split('\n')
for a in raw_data : 
    print a
    btc_history.append(eval(a))

This works for me in Python 3.6.0

I appreciate the help, I do think I have found a solution if someone would comment on the effectiveness I would appreciate it. Essentially what I did is. I realize it is somewhat static in its implementation but I does what I need it to do (forgive incorrect syntax)

SELECT
  ordered_item.id as `Id`,
  ordered_item.Item_Name as `ItemName`,
  Options1.Value
  Options2.Value
FROM ORDERED_ITEMS
LEFT JOIN (Ordered_Options as Options1)
    ON (Options1.Ordered_Item.ID = Ordered_Options.Ordered_Item_ID 
        AND Options1.Option_Number = 43)
LEFT JOIN (Ordered_Options as Options2)
    ON (Options2.Ordered_Item.ID = Ordered_Options.Ordered_Item_ID
        AND Options2.Option_Number = 44);

(Ah, just re-read your question and see that this doesn't quite apply.)

Here is a sample program that makes uses the python logging module. This logging module has been in all versions since 2.3. In this sample the logging is configurable by command line options.

    # Output logging information to screen
    if not options.quiet:
        hdlr = logging.StreamHandler(sys.stderr)
        hdlr.setFormatter(formatter)

    # Output logging information to file
    logfile = os.path.join(options.logdir, "project.log")
    if options.clean and os.path.isfile(logfile):
        os.remove(logfile)
    hdlr2 = logging.FileHandler(logfile)
    hdlr2.setFormatter(formatter)
    logger.addHandler(hdlr2)

Here is a guide on how to manually sign an APK. It includes info about the new apk-signer introduced in build-tools 24.0.3 (10/2016)

Automated Process:

Use this tool (uses the new apksigner from Google):

https://github.com/patrickfav/uber-apk-signer

^{Disclaimer: Im the developer :)}

Manual Process:

Step 1: Generate Keystore (only once)

You need to generate a keystore once and use it to sign your unsigned apk. Use the keytool provided by the JDK found in %JAVA_HOME%/bin/

keytool -genkey -v -keystore my.keystore -keyalg RSA -keysize 2048 -validity 10000 -alias app

Step 2 or 4: Zipalign

zipalign which is a tool provided by the Android SDK found in e.g. %ANDROID_HOME%/sdk/build-tools/24.0.2/ is a mandatory optimzation step if you want to upload the apk to the Play Store.

zipalign -p 4 my.apk my-aligned.apk

Note: when using the old jarsigner you need to zipalign AFTER signing. When using the new apksigner method you do it BEFORE signing (confusing, I know). Invoking zipalign before apksigner works fine because apksigner preserves APK alignment and compression (unlike jarsigner).

You can verify the alignment with

zipalign -c 4 my-aligned.apk

Step 3: Sign & Verify

Using build-tools 24.0.2 and older

Use jarsigner which, like the keytool, comes with the JDK distribution found in %JAVA_HOME%/bin/ and use it like so:

jarsigner -verbose -sigalg SHA1withRSA -digestalg SHA1 -keystore my.keystore my-app.apk my_alias_name

and can be verified with

jarsigner -verify -verbose my_application.apk

Using build-tools 24.0.3 and newer

Android 7.0 introduces APK Signature Scheme v2, a new app-signing scheme that offers faster app install times and more protection against unauthorized alterations to APK files (See here and here for more details). Threfore Google implemented their own apk signer called apksigner (duh!) The script file can be found in %ANDROID_HOME%/sdk/build-tools/24.0.3/ (the .jar is in the /lib subfolder). Use it like this

apksigner sign --ks my.keystore my-app.apk --ks-key-alias alias_name

and can be verified with

apksigner verify my-app.apk

The official documentation can be found here.

The easiest way is using shift(). If you have an array, the shift function shifts everything to the left.

var arr = [1, 2, 3, 4]; 
var theRemovedElement = arr.shift(); // theRemovedElement == 1
console.log(arr); // [2, 3, 4]

Use DATESTR

>> datestr(40189)
ans =
12-Jan-0110

Unfortunately, Excel starts counting at 1-Jan-1900. Find out how to convert serial dates from Matlab to Excel by using DATENUM

>> datenum(2010,1,11)
ans =
      734149
>> datenum(2010,1,11)-40189
ans =
      693960
>> datestr(40189+693960)
ans =
11-Jan-2010

In other words, to convert any serial Excel date, call

datestr(excelSerialDate + 693960)

EDIT

To get the date in mm/dd/yyyy format, call datestr with the specified format

excelSerialDate = 40189;
datestr(excelSerialDate + 693960,'mm/dd/yyyy')
ans =
01/11/2010

Also, if you want to get rid of the leading zero for the month, you can use REGEXPREP to fix things

excelSerialDate = 40189;
regexprep(datestr(excelSerialDate + 693960,'mm/dd/yyyy'),'^0','')
ans =
1/11/2010

python -m timeit -h

There are two solutions to fix this:

1. Use clear:both after the last floated tag. This works good.
2. If you have fixed height for your div or clipping of content is fine, go with: overflow: hidden

• in the parent pom application==> Version put the tag as follows: x.x.x-SNAPSHOT

example :0.0.1-SNAPSHOT

• "-SNAPSHOT" : is very important

Step 1) Create Profile and Account

You need to create a profile and account using the Configure Database Mail Wizard which can be accessed from the Configure Database Mail context menu of the Database Mail node in Management Node. This wizard is used to manage accounts, profiles, and Database Mail global settings.

Step 2)

RUN:

sp_CONFIGURE 'show advanced', 1
GO
RECONFIGURE
GO
sp_CONFIGURE 'Database Mail XPs', 1
GO
RECONFIGURE
GO

Step 3)

USE msdb
GO
EXEC sp_send_dbmail @profile_name='yourprofilename',
@recipients='[email protected]',
@subject='Test message',
@body='This is the body of the test message.
Congrates Database Mail Received By you Successfully.'

To loop through the table

DECLARE @email_id NVARCHAR(450), @id BIGINT, @max_id BIGINT, @query NVARCHAR(1000)

SELECT @id=MIN(id), @max_id=MAX(id) FROM [email_adresses]

WHILE @id<=@max_id
BEGIN
    SELECT @email_id=email_id 
    FROM [email_adresses]

    set @query='sp_send_dbmail @profile_name=''yourprofilename'',
                        @recipients='''+@email_id+''',
                        @subject=''Test message'',
                        @body=''This is the body of the test message.
                        Congrates Database Mail Received By you Successfully.'''

    EXEC @query
    SELECT @id=MIN(id) FROM [email_adresses] where id>@id

END

Posted this on the following link http://ms-sql-queries.blogspot.in/2012/12/how-to-send-email-from-sql-server.html

$customer_id = get_current_user_id();
print get_user_meta( $customer_id, 'billing_first_name', true );

Use this app : Servers Ultimate
With this app can run any server you can imagine on your android device (php, mysql, ftp, dhcp, ...) your phone will be a real server, just install the app click on (+) sign to add server, if the server is not installed the app will ask to download the package. You can access your server via LAN or WAN easily.

Filters as the name suggest used to perform filtering on either the request to a resource or on the response from a resource, or both. Spring Boot provides few options to register custom filters in the Spring Boot application. Let’s look at the different options.

1. Define Spring Boot Filter and Invocation Order

Implement Filter interface to create a new filter in Spring Boot.

@Configuration
@Order(Ordered.HIGHEST_PRECEDENCE)
public class CustomFilter implements Filter {

 private static final Logger LOGGER = LoggerFactory.getLogger(CustomFilter.class);

 @Override
 public void init(FilterConfig filterConfig) throws ServletException {
  LOGGER.info("########## Initiating Custom filter ##########");
 }

 @Override
 public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {

  HttpServletRequest request = (HttpServletRequest) servletRequest;
  HttpServletResponse response = (HttpServletResponse) servletResponse;

  LOGGER.info("Logging Request  {} : {}", request.getMethod(), request.getRequestURI());

  //call next filter in the filter chain
  filterChain.doFilter(request, response);

  LOGGER.info("Logging Response :{}", response.getContentType());
 }

 @Override
 public void destroy() {
  // TODO: 7/4/18
 }
}

Let’s quickly look at some important points in the above code

• The filter registered by @Component annotation.

• To fire filters in the right order–we needed to use the @Order annotation.

  @Component
  @Order(1)
  public class CustomFirstFilter implements Filter {
  
  }
  @Component
  @Order(2)
  public class CustomSecondFilter implements Filter {
  
  }
  

In the above code, CustomFirstFilter will run before the CustomSecondFilter.

The lower the number, the higher the precedence

2. URL Pattern

If the convention-based mapping is not flexible enough, we can use FilterRegistrationBean for the complete control of the application. Here, don’t use @Component annotation for the filter class but register the filter using a FilterRegistrationBean.

 public class CustomURLFilter implements Filter {

 private static final Logger LOGGER = LoggerFactory.getLogger(CustomURLFilter.class);

 @Override
 public void init(FilterConfig filterConfig) throws ServletException {
  LOGGER.info("########## Initiating CustomURLFilter filter ##########");
 }

 @Override
 public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {

  HttpServletRequest request = (HttpServletRequest) servletRequest;
  HttpServletResponse response = (HttpServletResponse) servletResponse;

  LOGGER.info("This Filter is only called when request is mapped for /customer resource");

  //call next filter in the filter chain
  filterChain.doFilter(request, response);
 }

 @Override
 public void destroy() {

 }
}

Register the custom Filter using FilterRegistrationBean.

@Configuration
public class AppConfig {

 @Bean
 public FilterRegistrationBean < CustomURLFilter > filterRegistrationBean() {
  FilterRegistrationBean < CustomURLFilter > registrationBean = new FilterRegistrationBean();
  CustomURLFilter customURLFilter = new CustomURLFilter();

  registrationBean.setFilter(customURLFilter);
  registrationBean.addUrlPatterns("/greeting/*");
  registrationBean.setOrder(2); //set precedence
  return registrationBean;
 }
}

You also can Redirect within the Route as follows. This is for handle invalid routes.

<Route path='*' render={() => 
     (
       <Redirect to="/error"/>
     )
}/>

I had the same error. To fix the error:

1. Open the console menu Gallery Menu and select API Manager.
2. On the left, click Credentials and then click New Credentials.
3. Click Create Credentials.
4. Click API KEY.
5. Click Navigator Key (there are more options; It depends on when consumed).

You must use this new API Navigator Key, generated by the system.

You can make a class to extend FPDF and add this:

class utfFPDF extends FPDF {

function Cell($w, $h=0, $txt="", $border=0, $ln=0, $align='', $fill=false, $link='')
{
    if (!empty($txt)){
        if (mb_detect_encoding($txt, 'UTF-8', false)){
            $txt = iconv('UTF-8', 'ISO-8859-5', $txt);

        }
    }
    parent::Cell($w, $h, $txt, $border, $ln, $align, $fill, $link);

} 

}

Try this. It will work for sure.

var userInput = $('#txt_name').attr('value')

SQL Developer will look in the following location in this order for a tnsnames.ora file

1. $HOME/.tnsnames.ora
2. $TNS_ADMIN/tnsnames.ora
3. TNS_ADMIN lookup key in the registry
4. /etc/tnsnames.ora ( non-windows )
5. $ORACLE_HOME/network/admin/tnsnames.ora
6. LocalMachine\SOFTWARE\ORACLE\ORACLE_HOME_KEY
7. LocalMachine\SOFTWARE\ORACLE\ORACLE_HOME

To see which one SQL Developer is using, issue the command show tns in the worksheet

If your tnsnames.ora file is not getting recognized, use the following procedure:

1. Define an environmental variable called TNS_ADMIN to point to the folder that contains your tnsnames.ora file.

   In Windows, this is done by navigating to Control Panel > System > Advanced system settings > Environment Variables...

   In Linux, define the TNS_ADMIN variable in the .profile file in your home directory.

2. Confirm the os is recognizing this environmental variable

   From the Windows command line: echo %TNS_ADMIN%

   From linux: echo $TNS_ADMIN

3. Restart SQL Developer

4. Now in SQL Developer right click on Connections and select New Connection.... Select TNS as connection type in the drop down box. Your entries from tnsnames.ora should now display here.

this worked for me inside a directive and works without refreshing the baseurl (just adds the endpoint).Good for Single Page Apps with routing mechanism.

  $(location).attr('href', 'http://localhost:10005/#/endpoint') 

If you are using jaxrs or any other, then there will be a class called mediatype.User interceptor before sending the request and compare it against this.

Java's import statement is pure syntactical sugar. import is only evaluated at compile time to indicate to the compiler where to find the names in the code.

You may live without any import statement when you always specify the full qualified name of classes. Like this line needs no import statement at all:

javax.swing.JButton but = new  javax.swing.JButton();

The import statement will make your code more readable like this:

import javax.swing.*;

JButton but = new JButton();

What I usually do is git reset #commit_hash

to the last commit where I think rebase had no effect.

then git pull

Now your branch should match exactly like master and rebased commits should not be in it.

Now one can just cherry-pick the commits on this branch.

If you want to break a string literal onto multiple lines, you can concatenate multiple strings together, one on each line, like so:

printf("name: %s\t"
"args: %s\t"
"value %d\t"
"arraysize %d\n", 
sp->name, 
sp->args, 
sp->value, 
sp->arraysize);

Since Java 8

        mixedArrayList.forEach((o) -> {
            String type = o.getClass().getSimpleName();
            switch (type) {
                case "String":
                    // treat as a String
                    break;
                case "Integer":
                    // treat as an int
                    break;
                case "Double":
                    // treat as a double
                    break;
                ...
                default:
                    // whatever
            }
        });

You do not need to parse every single line and then concatenate them again...

Source.fromFile(path)(Codec.UTF8).mkString

I prefer to use this:

import scala.io.{BufferedSource, Codec, Source}
import scala.util.Try

def readFileUtf8(path: String): Try[String] = Try {
  val source: BufferedSource = Source.fromFile(path)(Codec.UTF8)
  val content = source.mkString
  source.close()
  content
}

If you are looking to do an exact match, use the following syntax: (param)?.

Eg.

<Route path={`my/(exact)?/path`} component={MyComponent} />

The nice thing about this is that you'll have props.match to play with, and you don't need to worry about checking the value of the optional parameter:

{ props: { match: { "0": "exact" } } }

This might work for you:

OIFS=$IFS; IFS=$'\n'; array=($(ls -ls)); IFS=$OIFS; echo "${array[1]}"

Here is a solution for the single column search using PATINDEX.
It also displays the StartPosition, InvalidCharacter and ASCII code.

select line,
  patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,Line) as [Position],
  substring(line,patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,Line),1) as [InvalidCharacter],
  ascii(substring(line,patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,Line),1)) as [ASCIICode]
from  staging.APARMRE1
where patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,Line) >0

If you have 32-bit Windows, this method is not working without following settings.

1. Run prompt cmd.exe (important : Run As Administrator)
2. type bcdedit.exe and run
3. Look at the "increaseuserva" params and there is no then write following statement
4. bcdedit /set increaseuserva 3072
5. and again step 2 and check params

We added this settings and this block started.

if exist "$(DevEnvDir)..\tools\vsvars32.bat" (
   call "$(DevEnvDir)..\tools\vsvars32.bat"
   editbin /largeaddressaware "$(TargetPath)"

None of those worked for me, so I had three commits to revert (the last three commits), so I did:

git revert HEAD
git revert HEAD~2
git revert HEAD~4
git rebase -i HEAD~3 # pick, squash, squash

Worked like a charm :)

Simply put, casting is more efficient than creating a Double object.

Solution without page reload

<?php
  function removeday() { echo 'Day removed'; }

  if (isset($_GET['remove'])) { return removeday(); }
?>


<!DOCTYPE html><html><title>Days</title><body>

  <a href="" onclick="removeday(event)" class="deletebtn">Delete</a>

  <script>
  async function removeday(e) {
    e.preventDefault(); 
    document.body.innerHTML+= '<br>'+ await(await fetch('?remove=1')).text();

You can do it using dynamic instead of object:

dynamic item = AnyFunction(....);
string value = item.name;

Note that the Dynamic Language Runtime (DLR) has built-in caching mechanisms, so subsequent calls are very fast.

string test = "<body><head>test header</head></body>";

XmlDocument xmltest = new XmlDocument();
xmltest.LoadXml(test);

XmlNodeList elemlist = xmltest.GetElementsByTagName("head");

string result = elemlist[0].InnerXml; 

//result -> "test header"

Is the value of your particular COMMENT column null?

Sometimes NOT LIKE doesn't know how to behave properly around nulls.

Only this sample working without problem:

var crop = new Rectangle(0, y, bitmap.Width, h);
var bmp = new Bitmap(bitmap.Width, h);
var tempfile = Application.StartupPath+"\\"+"TEMP"+"\\"+Path.GetRandomFileName();


using (var gr = Graphics.FromImage(bmp))
{
    try
    {
        var dest = new Rectangle(0, 0, bitmap.Width, h);
        gr.DrawImage(image,dest , crop, GraphicsUnit.Point);
        bmp.Save(tempfile,ImageFormat.Jpeg);
        bmp.Dispose();
    }
    catch (Exception)
    {


    }

}

If you only need to remove duplicates then use DISTINCT. GROUP BY should be used to apply aggregate operators to each group

GROUP BY v DISTINCT

When using Bash, the first of ~/.bash_profile, ~/.bash_login and ~/.profile will be run for an interactive login shell. I believe ~/.profile is generally run by Unix shells besides Bash. Bash will run ~/.bashrc for a non-login interactive shell.

I typically put everything I want to always set in .bashrc and then run it from .bash_profile, where I also set up a few things that should run only when I'm logging in, such as setting up ssh-agent or running screen.

You can apply the .toUpperCase() directly on String variables or as an attribute to text fields. Ex: -

String str;
TextView txt;

str.toUpperCase();// will change it to all upper case OR
txt.append(str.toUpperCase());
txt.setText(str.toUpperCase());

Very effective solution here for WindowsForms TextBox control. (not sure about XAML).

This will work in Multliline mode also.

Probably it may be extended for other controls, like ComboBox control (not checked)

=IF(CR<=10, "RED", if(CR<50, "YELLOW", if(CR<101, "GREEN")))

CR = ColRow (Cell) This is an example. In this example when value in Cell is less then or equal to 10 then RED word will appear on that cell. In the same manner other if conditions are true if first if is false.

The name open addressing refers to the fact that the location ("address") of the element is not determined by its hash value. (This method is also called closed hashing).

In separate chaining, each bucket is independent, and has some sort of ADT (list, binary search trees, etc) of entries with the same index. In a good hash table, each bucket has zero or one entries, because we need operations of order O(1) for insert, search, etc.

This is a example of separate chaining using C++ with a simple hash function using mod operator (clearly, a bad hash function)

Hadoop comes with a useful program called distcp for copying large amounts of data to and from Hadoop Filesystems in parallel. The canonical use case for distcp is for transferring data between two HDFS clusters. If the clusters are running identical versions of hadoop, then the hdfs scheme is appropriate to use.

$ hadoop distcp hdfs://namenode1/foo hdfs://namenode2/bar

The data in /foo directory of namenode1 will be copied to /bar directory of namenode2. If the /bar directory does not exist, it will create it. Also we can mention multiple source paths.

Similar to rsync command, distcp command by default will skip the files that already exist. We can also use -overwrite option to overwrite the existing files in destination directory. The option -update will only update the files that have changed.

$ hadoop distcp -update hdfs://namenode1/foo hdfs://namenode2/bar/foo

distcp can also be implemented as a MapReduce job where the work of copying is done by the maps that run in parallel across the cluster. There will be no reducers.

If trying to copy data between two HDFS clusters that are running different versions, the copy will process will fail, since the RPC systems are incompatible. In that case we need to use the read-only HTTP based HFTP filesystems to read from the source. Here the job has to run on destination cluster.

$ hadoop distcp hftp://namenode1:50070/foo hdfs://namenode2/bar

50070 is the default port number for namenode's embedded web server.

You can try this code for Swift

 let popup : PopupVC = self.storyboard?.instantiateViewControllerWithIdentifier("PopupVC") as! PopupVC
 let navigationController = UINavigationController(rootViewController: popup)
 navigationController.modalPresentationStyle = UIModalPresentationStyle.OverCurrentContext
 self.presentViewController(navigationController, animated: true, completion: nil)

For swift 4 latest syntax using extension

extension UIViewController {
    func presentOnRoot(`with` viewController : UIViewController){
        let navigationController = UINavigationController(rootViewController: viewController)
        navigationController.modalPresentationStyle = UIModalPresentationStyle.overCurrentContext
        self.present(navigationController, animated: false, completion: nil)

If you have custom defines and want to save them before cleaning, run the following in your build directory:

sed -ne '/variable specified on the command line/{n;s/.*/-D \0 \\/;p}' CMakeCache.txt

Then create a new build directory (or remove the old build directory and recreate it) and finally run cmake with the arguments you'll get with the script above.

You may use this command for listing the files for your own debuggable apk:

adb shell run-as com.corp.appName ls /data/data/com.corp.appName/cache

And this script for pulling from cache:

#!/bin/sh
adb shell "run-as com.corp.appName cat '/data/data/com.corp.appNamepp/$1' > '/sdcard/$1'"
adb pull "/sdcard/$1"
adb shell "rm '/sdcard/$1'"

Then you can pull a file from cache like this:

./pull.sh cache/someCachedData.txt

Root is not required.

You can create swap space using the following steps Here we are creating swap at /home/

1. dd if=/dev/zero of=/home/swapfile1 bs=1024 count=8388608
   Here count is kilobyte count of swap space

2. mkswap /home/swapfile1

3. vi /etc/fstab
   make entry :
   /home/swapfile1 swap swap defaults 0 0

4. run:
   swapon -a

My solution, as answered here, is to use:

    var json = require('./data.json'); //with path

The file is loaded only once, further requests use cache.

edit To avoid caching, here's the helper function from this blogpost given in the comments, using the fs module:

var readJson = (path, cb) => {
  fs.readFile(require.resolve(path), (err, data) => {
    if (err)
      cb(err)
    else
      cb(null, JSON.parse(data))
  })
}

if you want to invoke ps1 scripts from cmd and pass arguments without invoking the script like

powershell.exe script.ps1 -c test
script -c test ( wont work )

you can do the following

setx PATHEXT "%PATHEXT%;.PS1;" /m
assoc .ps1=Microsoft.PowerShellScript.1
ftype Microsoft.PowerShellScript.1=powershell.exe "%1" %*

This is assuming powershell.exe is in your path

It's the other way round:

Vehicle[] car = new Vehicle[N];

This makes more sense, as the number of elements in the array isn't part of the type of car, but it is part of the initialization of the array whose reference you're initially assigning to car. You can then reassign it in another statement:

car = new Vehicle[10]; // Creates a new array

(Note that I've changed the type name to match Java naming conventions.)

For further information about arrays, see section 10 of the Java Language Specification.

What is the difference between exit(0) and exit(1) in C language?

exit(0) indicates successful program termination & it is fully portable, While
exit(1) (usually) indicates unsucessful termination. However, it's usage is non-portable.

Note that the C standard defines EXIT_SUCCESS and EXIT_FAILURE to return termination status from a C program.

0 and EXIT_SUCCESS are the values specified by the standard to indicate successful termination, however, only EXIT_FAILURE is the standard value for returning unsucessful termination. 1 is used for the same in many implementations though.

Reference:

C99 Standard: 7.20.4.3 The exit function
Para 5

Finally, control is returned to the host environment. If the value of status is zero or EXIT_SUCCESS, an implementation-de?ned form of the status successful termination is returned. If the value of status is EXIT_FAILURE , an implementation-de?ned form of the status unsuccessful termination is returned. Otherwise the status returned is implementation-de?ned.

• The @@identity function returns the last identity created in the same session.
• The scope_identity() function returns the last identity created in the same session and the same scope.
• The ident_current(name) returns the last identity created for a specific table or view in any session.
• The identity() function is not used to get an identity, it's used to create an identity in a select...into query.

The session is the database connection. The scope is the current query or the current stored procedure.

A situation where the scope_identity() and the @@identity functions differ, is if you have a trigger on the table. If you have a query that inserts a record, causing the trigger to insert another record somewhere, the scope_identity() function will return the identity created by the query, while the @@identity function will return the identity created by the trigger.

So, normally you would use the scope_identity() function.

DP size of any device is (actual resolution / density conversion factor).

Density conversion factor for density buckets are as follows:

ldpi: 0.75
mdpi: 1.0 (base density)
hdpi: 1.5
xhdpi: 2.0
xxhdpi: 3.0
xxxhdpi: 4.0

Examples of resolution/density conversion to DP:

• ldpi device of 240 X 320 px will be of 320 X 426.66 DP. 240 / 0.75 = 320 dp 320 / 0.75 = 426.66 dp

• xxhdpi device of 1080 x 1920 pixels (Samsung S4, S5) will be of 360 X 640 dp. 1080 / 3 = 360 dp 1920 / 3 = 640 dp

The canvas element provides a toDataURL method which returns a data: URL that includes the base64-encoded image data in a given format. For example:

var jpegUrl = canvas.toDataURL("image/jpeg");
var pngUrl = canvas.toDataURL(); // PNG is the default

Although the return value is not just the base64 encoded binary data, it's a simple matter to trim off the scheme and the file type to get just the data you want.

The toDataURL method will fail if the browser thinks you've drawn to the canvas any data that was loaded from a different origin, so this approach will only work if your image files are loaded from the same server as the HTML page whose script is performing this operation.

For more information see the MDN docs on the canvas API, which includes details on toDataURL, and the Wikipedia article on the data: URI scheme, which includes details on the format of the URI you'll receive from this call.

Sidenote, if you want to concatenate one string to all of the column names, you can just use this simple code.

colnames(df) <- paste("renamed_",colnames(df),sep="")

You can copy subscribers dictionary object to a same type of temporary dictionary object and then iterate the temporary dictionary object using foreach loop.

Try this:

{ "dt" : { "$gte" : ISODate("2013-10-01") } }

In my case, I copied the project and pasted it as another project. The Global.asax file contains the wrong file name, so I just change

<%@ Application Codebehind="Global.asax.cs" 
    Inherits="WrongAppname.MvcApplication" Language="C#" %>

to

<%@ Application Codebehind="Global.asax.cs" 
    Inherits="RightAppName.MvcApplication" Language="C#" %>

From the context, the conflict was caused by the version of the package.
Let's take a look the manual about rpm:

--force
    Same as using --replacepkgs, --replacefiles, and --oldpackage.

--oldpackage
    Allow an upgrade to replace a newer package with an older one.

So, you can execute the command rpm -Uvh info-4.13a-2.rpm --force to solve your issue.

Not for entire application or particular class.

CurrentUICulture and CurrentCulture are settable per thread as discussed here Is there a way of setting culture for a whole application? All current threads and new threads?. You can't change InvariantCulture at all.

Sample code to change cultures for current thread:

CultureInfo ci = new CultureInfo(theCultureString);
Thread.CurrentThread.CurrentCulture = ci;
Thread.CurrentThread.CurrentUICulture = ci;

For class you can set/restore culture inside critical methods, but it would be significantly safe to use appropriate overrides for most formatting related methods that take culture as one of arguments:

(3.3).ToString(new CultureInfo("fr-FR"))

I was able to go around the whole thing by replacing the context reference from this or Context.this to getapplicationcontext.

This only works if you control both the outside page and the iframe page.

On the outside page, make the iframe unscrollable.

<iframe src="" height=200 scrolling=no></iframe>

On the iframe page, add this.

<!doctype html>
...
<style>
html, body {height:100%; overflow:hidden}
body {overflow:auto; -webkit-overflow-scrolling:touch}
</style>

This works because modern browsers uses html to determine the height, so we just give that a fixed height and turn the body into a scrollable node.

Try this instead:

String scheme = req.getScheme();             
String serverName = req.getServerName(); 
int serverPort = req.getServerPort();    
String uri = (String) req.getAttribute("javax.servlet.forward.request_uri");
String prmstr = (String) req.getAttribute("javax.servlet.forward.query_string");
String url = scheme + "://" +serverName + ":" + serverPort + uri + "?" + prmstr;

Note: You can't get HREF anchor from your url. Example, if you have url "toc.html#top" then you can get only "toc.html"

Note: req.getAttribute("javax.servlet.forward.request_uri") work only in JSP. if you run this in controller before JSP then result is null

You can use code for both variant:

public static String getCurrentUrl(HttpServletRequest req) {
    String url = getCurrentUrlWithoutParams(req);
    String prmstr = getCurrentUrlParams(req);
    url += "?" + prmstr;
    return url;
}

public static String getCurrentUrlParams(HttpServletRequest request) {
    return StringUtil.safeString(request.getQueryString());
}

public static String getCurrentUrlWithoutParams(HttpServletRequest request) {
    String uri = (String) request.getAttribute("javax.servlet.forward.request_uri");
    if (uri == null) {
        return request.getRequestURL().toString();
    }
    String scheme = request.getScheme();
    String serverName = request.getServerName();
    int serverPort = request.getServerPort();
    String url = scheme + "://" + serverName + ":" + serverPort + uri;
    return url;
}

You're close. This should do the trick:

new {items = new [] {
    new {name = "command" , index = "X", optional = "0"}, 
    new {name = "command" , index = "X", optional = "0"}
}}

If your source was an enumerable of some sort, you might want to do this:

new {items = source.Select(item => new 
{
    name = item.Name, index = item.Index, options = item.Optional
})};

this is how you can create an array of boolean in TS and initialize it with false:

var array: boolean[] = [false, false, false]

or another approach can be:

var array2: Array<boolean> =[false, false, false] 

you can specify the type after the colon which in this case is boolean array

The major exact difference between DLL and EXE that DLL hasn't got an entry point and EXE does. If you are familiar with c++ you can see that build EXE has main() entry function and DLL doesn't :)

None of the above worked for me, the only one working was

insert into tableName  
select 11, 'BALOO' from sysibm.sysdummy1 union all
select 22, nullif('','') AS nullColumn from sysibm.sysdummy1

The nullif is used since it is not possible to pass null in the select statement otherwise.

With Jquery... You can add class to html elements like this:

$(".divclass").find("p,h1,h2,h3,figure,span,a").addClass('nameclassorid');

nameclassorid no point or # at the beginning

This does in fact relate to the long standing issue at http://jira.mongodb.org/browse/SERVER-1243 where there are in fact a number of challenges to a clear syntax that supports "all cases" where mutiple array matches are found. There are in fact methods already in place that "aid" in solutions to this problem, such as Bulk Operations which have been implemented after this original post.

It is still not possible to update more than a single matched array element in a single update statement, so even with a "multi" update all you will ever be able to update is just one mathed element in the array for each document in that single statement.

The best possible solution at present is to find and loop all matched documents and process Bulk updates which will at least allow many operations to be sent in a single request with a singular response. You can optionally use .aggregate() to reduce the array content returned in the search result to just those that match the conditions for the update selection:

db.collection.aggregate([
    { "$match": { "events.handled": 1 } },
    { "$project": {
        "events": {
            "$setDifference": [
               { "$map": {
                   "input": "$events",
                   "as": "event",
                   "in": {
                       "$cond": [
                           { "$eq": [ "$$event.handled", 1 ] },
                           "$$el",
                           false
                       ]
                   }
               }},
               [false]
            ]
        }
    }}
]).forEach(function(doc) {
    doc.events.forEach(function(event) {
        bulk.find({ "_id": doc._id, "events.handled": 1  }).updateOne({
            "$set": { "events.$.handled": 0 }
        });
        count++;

        if ( count % 1000 == 0 ) {
            bulk.execute();
            bulk = db.collection.initializeOrderedBulkOp();
        }
    });
});

if ( count % 1000 != 0 )
    bulk.execute();

The .aggregate() portion there will work when there is a "unique" identifier for the array or all content for each element forms a "unique" element itself. This is due to the "set" operator in $setDifference used to filter any false values returned from the $map operation used to process the array for matches.

If your array content does not have unique elements you can try an alternate approach with $redact:

db.collection.aggregate([
    { "$match": { "events.handled": 1 } },
    { "$redact": {
        "$cond": {
            "if": {
                "$eq": [ { "$ifNull": [ "$handled", 1 ] }, 1 ]
            },
            "then": "$$DESCEND",
            "else": "$$PRUNE"
        }
    }}
])

Where it's limitation is that if "handled" was in fact a field meant to be present at other document levels then you are likely going to get unexepected results, but is fine where that field appears only in one document position and is an equality match.

Future releases ( post 3.1 MongoDB ) as of writing will have a $filter operation that is simpler:

db.collection.aggregate([
    { "$match": { "events.handled": 1 } },
    { "$project": {
        "events": {
            "$filter": {
                "input": "$events",
                "as": "event",
                "cond": { "$eq": [ "$$event.handled", 1 ] }
            }
        }
    }}
])

And all releases that support .aggregate() can use the following approach with $unwind, but the usage of that operator makes it the least efficient approach due to the array expansion in the pipeline:

db.collection.aggregate([
    { "$match": { "events.handled": 1 } },
    { "$unwind": "$events" },
    { "$match": { "events.handled": 1 } },
    { "$group": {
        "_id": "$_id",
        "events": { "$push": "$events" }
    }}        
])

In all cases where the MongoDB version supports a "cursor" from aggregate output, then this is just a matter of choosing an approach and iterating the results with the same block of code shown to process the Bulk update statements. Bulk Operations and "cursors" from aggregate output are introduced in the same version ( MongoDB 2.6 ) and therefore usually work hand in hand for processing.

In even earlier versions then it is probably best to just use .find() to return the cursor, and filter out the execution of statements to just the number of times the array element is matched for the .update() iterations:

db.collection.find({ "events.handled": 1 }).forEach(function(doc){ 
    doc.events.filter(function(event){ return event.handled == 1 }).forEach(function(event){
        db.collection.update({ "_id": doc._id },{ "$set": { "events.$.handled": 0 }});
    });
});

If you are aboslutely determined to do "multi" updates or deem that to be ultimately more efficient than processing multiple updates for each matched document, then you can always determine the maximum number of possible array matches and just execute a "multi" update that many times, until basically there are no more documents to update.

A valid approach for MongoDB 2.4 and 2.2 versions could also use .aggregate() to find this value:

var result = db.collection.aggregate([
    { "$match": { "events.handled": 1 } },
    { "$unwind": "$events" },
    { "$match": { "events.handled": 1 } },
    { "$group": {
        "_id": "$_id",
        "count": { "$sum": 1 }
    }},
    { "$group": {
        "_id": null,
        "count": { "$max": "$count" }
    }}
]);

var max = result.result[0].count;

while ( max-- ) {
    db.collection.update({ "events.handled": 1},{ "$set": { "events.$.handled": 0 }},{ "multi": true })
}

Whatever the case, there are certain things you do not want to do within the update:

1. Do not "one shot" update the array: Where if you think it might be more efficient to update the whole array content in code and then just $set the whole array in each document. This might seem faster to process, but there is no guarantee that the array content has not changed since it was read and the update is performed. Though $set is still an atomic operator, it will only update the array with what it "thinks" is the correct data, and thus is likely to overwrite any changes occurring between read and write.

2. Do not calculate index values to update: Where similar to the "one shot" approach you just work out that position 0 and position 2 ( and so on ) are the elements to update and code these in with and eventual statement like:

   { "$set": {
       "events.0.handled": 0,
       "events.2.handled": 0
   }}
   

   Again the problem here is the "presumption" that those index values found when the document was read are the same index values in th array at the time of update. If new items are added to the array in a way that changes the order then those positions are not longer valid and the wrong items are in fact updated.

So until there is a reasonable syntax determined for allowing multiple matched array elements to be processed in single update statement then the basic approach is to either update each matched array element in an indvidual statement ( ideally in Bulk ) or essentially work out the maximum array elements to update or keep updating until no more modified results are returned. At any rate, you should "always" be processing positional $ updates on the matched array element, even if that is only updating one element per statement.

Bulk Operations are in fact the "generalized" solution to processing any operations that work out to be "multiple operations", and since there are more applications for this than merely updating mutiple array elements with the same value, then it has of course been implemented already, and it is presently the best approach to solve this problem.

the different way to disable test tasks in the project is:

tasks.withType(Test) {enabled = false}

this behavior needed sometimes if you want to disable tests in one of a project(or the group of projects).

This way working for the all kind of test task, not just a java 'tests'. Also, this way is safe. Here's what I mean let's say: you have a set of projects in different languages: if we try to add this kind of record in main build.gradle:

 subprojects{
 .......
 tests.enabled=false
 .......
}

we will fail in a project when if we have no task called tests

str_replace with arrays just performs all the replacements sequentially. Use strtr instead to do them all at once:

$new_message = strtr($message, 'lmnopq...', 'abcdef...');

It could also be because, it might not be able to found the .dll file required. Either the file is not in the folder or is renamed. I faced the same issue and found that .dll file was missing in my bin folder some how.

Eva M from above, almost had the answer as posted above (Thanks Eva M!):

var validator = $( "#myform" ).validate();
validator.form();

This is almost the answer, but it causes problems, in even the most up to date jquery validation plugin as of 13 DEC 2018. The problem is that if one directly copies that sample, and EVER calls ".validate()" more than once, the focus/key processing of the validation can get broken, and the validation may not show errors properly.

Here is how to use Eva M's answer, and ensure those focus/key/error-hiding issues do not occur:

1) Save your validator to a variable/global.

var oValidator = $("#myform").validate();

2) DO NOT call $("#myform").validate() EVER again.

If you call $("#myform").validate() more than once, it may cause focus/key/error-hiding issues.

3) Use the variable/global and call form.

var bIsValid = oValidator.form();

The non-recursive version of the function is not too hard - here it is for integers:

long powi(long x, unsigned n)
{
    long p = x;
    long r = 1;

    while (n > 0)
    {
        if (n % 2 == 1)
            r *= p;
        p *= p;
        n /= 2;
    }

    return(r);
}

(Hacked out of code for raising a double value to an integer power - had to remove the code to deal with reciprocals, for example.)

This option is no longer supported in recent versions of karma:

see https://github.com/karma-runner/karma/issues/1731#issuecomment-174227054

The files array can be redefined using the CLI as such:

karma start --files=Array("test/Spec/services/myServiceSpec.js")

or escaped:

karma start --files=Array\(\"test/Spec/services/myServiceSpec.js\"\)

Here's some quick-n-dirty code that uses jQuery to do what you want. I highly recommend using jQuery. It'll make things a lot more easier for you, especially since you're new to JavaScript.

<select id = "pricingOptions" name = "pricingOptions">
    <option value = "500">Option A</option>
    <option value = "1000">Option B</option>
</select>

<script type = "text/javascript" language = "javascript">
    jQuery(document).ready(function() {
        jQuery("#pricingOptions").change(function() {
            if(this.options[this.selectedIndex].value == "500") {
                window.location = "http://example.com/foo.php?option=500";
            }
        });
    });
</script>

The easiest way that I found for adding a column to a DataFrame was to use the "add" function. Here's a snippet of code, also with the output to a CSV file. Note that including the "columns" argument allows you to set the name of the column (which happens to be the same as the name of the np.array that I used as the source of the data).

#  now to create a PANDAS data frame
df = pd.DataFrame(data = FF_maxRSSBasal, columns=['FF_maxRSSBasal'])
# from here on, we use the trick of creating a new dataframe and then "add"ing it
df2 = pd.DataFrame(data = FF_maxRSSPrism, columns=['FF_maxRSSPrism'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = FF_maxRSSPyramidal, columns=['FF_maxRSSPyramidal'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = deltaFF_strainE22, columns=['deltaFF_strainE22'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = scaled, columns=['scaled'])
df = df.add( df2, fill_value=0 )
df2 = pd.DataFrame(data = deltaFF_orientation, columns=['deltaFF_orientation'])
df = df.add( df2, fill_value=0 )
#print(df)
df.to_csv('FF_data_frame.csv')

when it comes to security for transmitting data i.e Two way communication you use encryption.All encryption requires a key

when it comes to authorization you use hashing.There is no key in hashing

Hashing takes any amount of data (binary or text) and creates a constant-length hash representing a checksum for the data. For example, the hash might be 16 bytes. Different hashing algorithms produce different size hashes. You obviously cannot re-create the original data from the hash, but you can hash the data again to see if the same hash value is generated. One-way Unix-based passwords work this way. The password is stored as a hash value, and to log onto a system, the password you type is hashed, and the hash value is compared against the hash of the real password. If they match, then you must've typed the correct password

why is hashing irreversible :

Hashing isn't reversible because the input-to-hash mapping is not 1-to-1. Having two inputs map to the same hash value is usually referred to as a "hash collision". For security purposes, one of the properties of a "good" hash function is that collisions are rare in practical use.

He who is Shy^* gave you the germ of an answer, but only the germ. The basic technique for converting a value into a string in the C pre-processor is indeed via the '#' operator, but a simple transliteration of the proposed solution gets a compilation error:

#define TEST_FUNC test_func
#define TEST_FUNC_NAME #TEST_FUNC

#include <stdio.h>
int main(void)
{
    puts(TEST_FUNC_NAME);
    return(0);
}

The syntax error is on the 'puts()' line - the problem is a 'stray #' in the source.

In section 6.10.3.2 of the C standard, 'The # operator', it says:

Each # preprocessing token in the replacement list for a function-like macro shall be followed by a parameter as the next preprocessing token in the replacement list.

The trouble is that you can convert macro arguments to strings -- but you can't convert random items that are not macro arguments.

So, to achieve the effect you are after, you most certainly have to do some extra work.

#define FUNCTION_NAME(name) #name
#define TEST_FUNC_NAME  FUNCTION_NAME(test_func)

#include <stdio.h>

int main(void)
{
    puts(TEST_FUNC_NAME);
    return(0);
}

I'm not completely clear on how you plan to use the macros, and how you plan to avoid repetition altogether. This slightly more elaborate example might be more informative. The use of a macro equivalent to STR_VALUE is an idiom that is necessary to get the desired result.

#define STR_VALUE(arg)      #arg
#define FUNCTION_NAME(name) STR_VALUE(name)

#define TEST_FUNC      test_func
#define TEST_FUNC_NAME FUNCTION_NAME(TEST_FUNC)

#include <stdio.h>

static void TEST_FUNC(void)
{
    printf("In function %s\n", TEST_FUNC_NAME);
}

int main(void)
{
    puts(TEST_FUNC_NAME);
    TEST_FUNC();
    return(0);
}

If you do not want to use numpy,

sorted(range(len(seq)), key=seq.__getitem__)

is fastest, as demonstrated here.

Assuming this is a personal certificate created by windows on the system you copied your project from, you can use the certificate manager on the system where the project is now and import the certificate. Start the certificate manager (certmgr) and select the personal certificates then right click below the list of existing certificates and select import from the tasks. Use the browse to find the .pfx in the project (the .pfx from the previous system that you copied over with the project). It should be in the sub-directory with the same name as the project directory. I am familiar with C# and VS, so if that is not your environment maybe the .pfx will be elsewhere or maybe this suggestion does not apply. After the import you should get a status message. If you succeeded, the compile certificate error should be gone.

A side from the very long complete accepted answer there is an important point to make about IndexOutOfRangeException compared with many other exception types, and that is:

Often there is complex program state that maybe difficult to have control over at a particular point in code e.g a DB connection goes down so data for an input cannot be retrieved etc... This kind of issue often results in an Exception of some kind that has to bubble up to a higher level because where it occurs has no way of dealing with it at that point.

IndexOutOfRangeException is generally different in that it in most cases it is pretty trivial to check for at the point where the exception is being raised. Generally this kind of exception get thrown by some code that could very easily deal with the issue at the place it is occurring - just by checking the actual length of the array. You don't want to 'fix' this by handling this exception higher up - but instead by ensuring its not thrown in the first instance - which in most cases is easy to do by checking the array length.

Another way of putting this is that other exceptions can arise due to genuine lack of control over input or program state BUT IndexOutOfRangeException more often than not is simply just pilot (programmer) error.

Just another note that you can a id/string enum with the following:

class EnumyObjects{
    public static BOUNCE={str:"Bounce",id:1};
    public static DROP={str:"Drop",id:2};
    public static FALL={str:"Fall",id:3};


}

If you are using a UNIX system, you could do

git log|grep "Author"|wc -l

You have three options:

• Xcode Organizer
• Jailbroken device with syslogd + openSSH
• Use dup2 to redirect all STDERR and STDOUT to a file and then "tail -f" that file (this last one is more a simulator thing, since you are stuck with the same problem of tailing a file on the device).

So, to get the 2º one you just need to install syslogd and OpenSSH from Cydia, restart required after to get syslogd going; now just open a ssh session to your device (via terminal or putty on windows), and type "tail -f /var/log/syslog". And there you go, wireless real time system log.

If you would like to try the 3º just search for "dup2" online, it's a system call.

You're getting that because VARCHAR is not a valid type to cast into. According to the MySQL docs (http://dev.mysql.com/doc/refman/5.5/en/cast-functions.html#function_cast) you can only cast to:

• BINARY[(N)]
• CHAR[(N)]
• DATE
• DATETIME
• DECIMAL[(M[,D])]
• SIGNED
• [INTEGER]
• TIME
• UNSIGNED [INTEGER]

I think your best-bet is to use CHAR.

a bit late to this, but yes rabbitmq has a build in tracer that allows you to see the incomming messages in a log. When enabled, you can just tail -f /var/tmp/rabbitmq-tracing/.log (on mac) to watch the messages.

I'd start by using one of the projects out there for Java and CUDA: http://www.jcuda.org/

I managed out how to make it works. Tell me in case I am wrong. I used only one way to serialize/deserialize: I removed all annotations regarding this (@JSONSerialize and @JSONDeserialize) and registered Serializers and Deserializers in CustomObjectMapper class. I didn't find an article explaining this behaviour but I resolved in this way. Hope it's useful.

Adding to what @KyleMit said, consider using:

• col-md-* classes for the larger outer columns
• col-xs-* classes for the smaller inner columns

This will be useful when you view the page on different screen sizes.

On a small screen, the wrapping of larger outer columns will then happen while maintaining the smaller inner columns, if possible

Yes, if you really want / need to do it you can use PowerMock. This should be considered a last resort. With PowerMock you can cause it to return a mock from the call to the constructor. Then do the verify on the mock. That said, csturtz's is the "right" answer.

Here is the link to Mock construction of new objects

$('selector').css('cursor', 'pointer'); // 'default' to revert

I know that may be confusing per your original question, but the "finger" cursor is actually called "pointer".

The normal arrow cursor is just "default".

I was getting the below as well trying to get out to github.com as our proxy re-writes the HTTPS connection with their self-signed cert:

no peer certificate available No client certificate CA names sent

In my output there was also:

Protocol : TLSv1.3

I added -tls1_2 and it worked fine and now I can see which CA it is using on the outgoing request. e.g.:
openssl s_client -connect github.com:443 -tls1_2

The question doesn't address multiline strings, but here is how you would strip leading whitespace from a multiline string using python's standard library textwrap module. If we had a string like:

s = """
    line 1 has 4 leading spaces
    line 2 has 4 leading spaces
    line 3 has 4 leading spaces
"""

if we print(s) we would get output like:

>>> print(s)
    this has 4 leading spaces 1
    this has 4 leading spaces 2
    this has 4 leading spaces 3

and if we used textwrap.dedent:

>>> import textwrap
>>> print(textwrap.dedent(s))
this has 4 leading spaces 1
this has 4 leading spaces 2
this has 4 leading spaces 3

Use case:

 sesssionStorage.setObj(1,{date:Date.now(),action:'save firstObject'});
 sesssionStorage.setObj(2,{date:Date.now(),action:'save 2nd object'}); 
 //Query first object
  sesssionStorage.getObj(1)
  //Retrieve date created of 2nd object
  new Date(sesssionStorage.getObj(1).date)

API

Storage.prototype.setObj = function(key, obj) {

        return this.setItem(key, JSON.stringify(obj))
    };
    
    Storage.prototype.getObj = function(key) {
        return JSON.parse(this.getItem(key))
    };

This is the code I ended up using. It stretches input & output cells to the left and right. Note that the input/output number indication will be gone:

from IPython.core.display import display, HTML
display(HTML("<style>.container { width:100% !important; }</style>"))
display(HTML("<style>.output_result { max-width:100% !important; }</style>"))
display(HTML("<style>.prompt { display:none !important; }</style>"))

No, one per customer prior to Java 7.

You can catch a superclass, like java.lang.Exception, as long as you take the same action in all cases.

try {
    // some code
} catch(Exception e) { //All exceptions are caught here as all are inheriting java.lang.Exception
    e.printStackTrace();
}

But that might not be the best practice. You should only catch an exception when you have a strategy for actually handling it - and logging and rethrowing is not "handling it". If you don't have a corrective action, better to add it to the method signature and let it bubble up to someone that can handle the situation.

Return data Should be below format

 label = u.person_full_name,
 value = u.user_id

Try perl -MCPAN -e "upgrade /(.\*)/". It works fine for me.

You can use ComboBox, then point your mouse to the upper arrow facing right, it will unfold a box called ComboBox Tasks and in there you can go ahead and edit your items or fill in the items / strings one per line. This should be the easiest.

Try setting the time on the mobile device and the Mac to "set date and time automatically" checkbox and restart xcode, that did it for me

public void Foo(IList<Bar> list)
{
     // Do Something with the list here.
}

In this case you could pass in any class which implements the IList<Bar> interface. If you used List<Bar> instead, only a List<Bar> instance could be passed in.

The IList<Bar> way is more loosely coupled than the List<Bar> way.

Below code is used in my application to send email with an attachment here the attachments is an image .You can send any type of file only thing is to keep in mind is that you had to specify the correct 'mimeType'

add this to your .h file

#import <MessageUI/MFMailComposeViewController.h>

Add MessageUI.framework to your project file

NSArray *paths = SSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask, YES);

NSString *documentsDirectory = [paths objectAtIndex:0];

NSString *getImagePath = [documentsDirectory stringByAppendingPathComponent:@"myGreenCard.png"];



MFMailComposeViewController* controller = [[MFMailComposeViewController alloc] init];
controller.mailComposeDelegate = self;
[controller setSubject:@"Green card application"];
[controller setMessageBody:@"Hi , <br/>  This is my new latest designed green card." isHTML:YES]; 
[controller addAttachmentData:[NSData dataWithContentsOfFile:getImagePath] mimeType:@"png" fileName:@"My Green Card"];
if (controller)
    [self presentModalViewController:controller animated:YES];
[controller release];

Delegate method is as shown below

  -(void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error;
{
    if (result == MFMailComposeResultSent) {
        NSLog(@"It's away!");
    }
    [self dismissModalViewControllerAnimated:YES];
}

Here is improved @lucasjones answer. I included improvements mentioned in comment section after his answer. I hope someone will find this useful.

public static string[] GetTypePropertyNames(object classObject,  BindingFlags bindingFlags)
{
    if (classObject == null)
    {
        throw new ArgumentNullException(nameof(classObject));
    }

        var type = classObject.GetType();
        var propertyInfos = type.GetProperties(bindingFlags);

        return propertyInfos.Select(propertyInfo => propertyInfo.Name).ToArray();
 }

For Linux users who can't use Microsoft Credential Manager. This is the only solution I found aside from using ssh. You need to generate the credentials in the repository view (See images below)

And the result is:

Copy the password!. Azure devops doesn't store it and you won't be able to see it again!

NB: As of 2020 Alternate credentials have been disabled check Microsoft blog

If you want to iterate over every item in the array as if it were a flattened array, you can just do:

foreach (int i in array) {
    Console.Write(i);
}

which would print

123456

If you want to be able to know the x and y indexes as well, you'll need to do:

for (int x = 0; x < array.GetLength(0); x += 1) {
    for (int y = 0; y < array.GetLength(1); y += 1) {
        Console.Write(array[x, y]);
    }
}

Alternatively you could use a jagged array instead (an array of arrays):

int[][] array = new int[2][] { new int[3] {1, 2, 3}, new int[3] {4, 5, 6} };
foreach (int[] subArray in array) {
    foreach (int i in subArray) {
        Console.Write(i);
    }
}

or

int[][] array = new int[2][] { new int[3] {1, 2, 3}, new int[3] {4, 5, 6} };
for (int j = 0; j < array.Length; j += 1) {
    for (int k = 0; k < array[j].Length; k += 1) {
        Console.Write(array[j][k]);
    }
}

Using code like this in a form I can capture the original source upload filename, copy it to a second simple input field. This is so user can provide an alternate upload filename in submit request since the file upload filename is immutable.

    <input type="file" id="imgup1" name="imagefile">
      onchange="document.getElementsByName('imgfn1')[0].value = document.getElementById('imgup1').value;">
    <input type="text" name="imgfn1" value="">

As per the HTML:

<html>
    <body>
    <p class="content">Link1.</p>
    </body>
<html>
<html>
    <body>
    <p class="content">Link2.</p>
    </body>
<html>

Two(2) <p> elements are having the same class content.

So to filter the elements having the same class i.e. content and create a list you can use either of the following Locator Strategies:

• Using class_name:

  elements = driver.find_elements_by_class_name("content")
  

• Using css_selector:

   elements = driver.find_elements_by_css_selector(".content")
  

• Using xpath:

  elements = driver.find_elements_by_xpath("//*[@class='content']")
  

Ideally, to click on the element you need to induce WebDriverWait for the visibility_of_all_elements_located() and you can use either of the following Locator Strategies:

• Using CLASS_NAME:

  elements = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CLASS_NAME, "content")))
  

• Using CSS_SELECTOR:

  elements = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, ".content")))
  

• Using XPATH:

  elements = WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//*[@class='content']")))
  

• Note : You have to add the following imports :

  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC

Try this:

<script>
var form_original_data = $("form").serialize(); 
var form_submit=false;
$('[type="submit"]').click(function() {
    form_submit=true;
});
window.onbeforeunload = function() {

You may store the parameters for the blob detector in a file, but this is not necessary. Example:

// set up the parameters (check the defaults in opencv's code in blobdetector.cpp)
cv::SimpleBlobDetector::Params params;
params.minDistBetweenBlobs = 50.0f;
params.filterByInertia = false;
params.filterByConvexity = false;
params.filterByColor = false;
params.filterByCircularity = false;
params.filterByArea = true;
params.minArea = 20.0f;
params.maxArea = 500.0f;
// ... any other params you don't want default value

// set up and create the detector using the parameters
cv::SimpleBlobDetector blob_detector(params);
// or cv::Ptr<cv::SimpleBlobDetector> detector = cv::SimpleBlobDetector::create(params)

// detect!
vector<cv::KeyPoint> keypoints;
blob_detector.detect(image, keypoints);

// extract the x y coordinates of the keypoints: 

for (int i=0; i<keypoints.size(); i++){
    float X = keypoints[i].pt.x; 
    float Y = keypoints[i].pt.y;
}

>>> myDict
{'lastName': ['Stone', 'Lee'], 'age': ['12'], 'firstName': ['Alan', 'Mary-Ann'],
 'address': ['34 Main Street, 212 First Avenue']}

>>> Set = set()

>>> not ['' for Key, Values in myDict.items() for Value in Values if 'Mary' in Value and Set.add(Key)] and list(Set)
['firstName']

So Nodejs comes with the default global variable called '__fileName' that holds the current file being executed My advice is to pass the __fileName to a service from any file , so that the retrieval of the fileName is made dynamic

Below, I make use of the fileName string and then split it based on the path.sep. Note path.sep avoids issues with posix file seperators and windows file seperators (issues with '/' and '\'). It is much cleaner. Getting the substring and getting only the last seperated name and subtracting it with the actulal length by 3 speaks for itself.

You can write a service like this (Note this is in typescript , but you can very well write it in js )

export class AppLoggingConstants {

    constructor(){

    }
      // Here make sure the fileName param is actually '__fileName'
    getDefaultMedata(fileName: string, methodName: string) {
        const appName = APP_NAME;
        const actualFileName = fileName.substring(fileName.lastIndexOf(path.sep)+1, fileName.length - 3);
        //const actualFileName = fileName;
     return appName+ ' -- '+actualFileName;
    }


}

export const AppLoggingConstantsInstance = new AppLoggingConstants();

Concept and code here

I have created a simple example for using AsyncTask of Android. It starts with onPreExecute(), doInBackground(), publishProgress() and finally onProgressUpdate().

In this, doInBackground() works as a background thread, while other works in the UI Thread. You can't access an UI element in doInBackground(). The sequence is the same as I have mentioned.

However, if you need to update any widget from doInBackground, you can publishProgress from doInBackground which will call onProgressUpdate to update your UI widget.

class TestAsync extends AsyncTask<Void, Integer, String> {
    String TAG = getClass().getSimpleName();

    protected void onPreExecute() {
        super.onPreExecute();
        Log.d(TAG + " PreExceute","On pre Exceute......");
    }

    protected String doInBackground(Void...arg0) {
        Log.d(TAG + " DoINBackGround", "On doInBackground...");

        for (int i=0; i<10; i++){
            Integer in = new Integer(i);
            publishProgress(i);
        }
        return "You are at PostExecute";
    }

    protected void onProgressUpdate(Integer...a) {
        super.onProgressUpdate(a);
        Log.d(TAG + " onProgressUpdate", "You are in progress update ... " + a[0]);
    }

    protected void onPostExecute(String result) {
        super.onPostExecute(result);
        Log.d(TAG + " onPostExecute", "" + result);
    }
}

Call it like this in your activity:

new TestAsync().execute();

I think, the statement

everyone hates it except me

makes any further discussion waste: when you keep using Git, they will blame you if anything goes wrong.

Apart from this, for me Git has two advantages over a centralized VCS that I appreciate most (as partly described by Rob Sobers):

• automatic backup of the whole repo: everytime someone pulls from the central repo, he/she gets a full history of the changes. When one repo gets lost: don't worry, take one of those present on every workstation.
• offline repo access: when I'm working at home (or in an airplane or train), I can see the full history of the project, every single checkin, without starting up my VPN connection to work and can work like I were at work: checkin, checkout, branch, anything.

But as I said: I think that you're fighting a lost battle: when everyone hates Git, don't use Git. It could help you more to know why they hate Git instead of trying them to convince them.

If they simply don't want it 'cause it's new to them and are not willing to learn something new: are you sure that you will do successful development with that staff?

Does really every single person hate Git or are they influenced by some opinion leaders? Find the leaders and ask them what's the problem. Convince them and you'll convince the rest of the team.

If you cannot convince the leaders: forget about using Git, take the TFS. Will make your life easier.

I had similar issue on MacBook Pro, I just followed the below link and issue got resolved. https://projectlombok.org/setup/eclipse

Steps followed:-

• Download the lombok.jar
• Double click on this jar
• This jar will try to find the eclipse installed on the machine, but in my case it was not able to identify the eclipse though I installed on it, this could be due to softlink to the eclipse path.
• I just specified the location of the eclipse ini file by clicking "Specify location" button
• This jar automatically updated the entry in eclipse.ini file for javaagent
  • I added the same jar to the classpath of the project in the eclipse
  • Restarted my eclipse

One liner:

<? if (have_posts()):while(have_posts()): the_post(); the_content(); endwhile; endif; ?>

Depending on the encoding you wish to use:

var str = System.Text.Encoding.Default.GetString(result);

With this code you can get the JVM arguments:

import java.lang.management.ManagementFactory;
import java.lang.management.RuntimeMXBean;
...
RuntimeMXBean runtimeMxBean = ManagementFactory.getRuntimeMXBean();
List<String> arguments = runtimeMxBean.getInputArguments();

Many of these answers reference old POI documentation and classes. In the newest POI 3.16, Cell with the int types has been deprecated

Cell.CELL_TYPE_STRING

Instead the CellType enum can be used.

CellType.STRING 

Just be sure to update your pom with the poi dependency as well as the poi-ooxml dependency to the new 3.16 version otherwise you will continue to get exceptions. One advantage with this version is that you can specify the cell type at the time the cell is created eliminating all the extra steps described in previous answers:

titleRowCell = currentReportRow.createCell(currentReportColumnIndex, CellType.STRING);

my implementation is very simple, count the number of lines in the input (and minimum 2 rows to show that it's a textarea):

textarea.rows = Math.max(2, textarea.value.split("\n").length) // # oninput

full working example with stimulus: https://jsbin.com/kajosolini/1/edit?html,js,output

(and this works with the browser's manual resize handle for instance)

You can use the values() method of a queryset, which returns a dictionary. Further, this method accepts a list of fields to subset on. The values() method will not work with get(), so you must use filter() (refer to the QuerySet API).

In view...

def show(request, object_id):
   object = Foo.objects.filter(id=object_id).values()[0]
   return render_to_response('detail.html', {'object': object})

In detail.html...

<ul>
   {% for key, value in object.items %}
        <li><b>{{ key }}:</b> {{ value }}</li>
   {% endfor %}
</ul>

For a collection of instances returned by filter:

   object = Foo.objects.filter(id=object_id).values() # no [0]

In detail.html...

{% for instance in object %}
<h1>{{ instance.id }}</h1>
<ul>
    {% for key, value in instance.items %}
        <li><b>{{ key }}:</b>  {{ value }}</li>
    {% endfor %}
</ul>
{% endfor %}

In your MakeFile or CMakeLists.txt you can set CMAKE_CXX_FLAGS as below:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -I/path/to/your/folder")

to Hide All Errors:

error_reporting(0);
ini_set('display_errors', 0);

to Show All Errors:

error_reporting(E_ALL);
ini_set('display_errors', 1);

And the Swift version of the Wasif's answer:

Swift 2.x

var token = deviceToken.description.stringByTrimmingCharactersInSet(NSCharacterSet(charactersInString: "<>"))
token = token.stringByReplacingOccurrencesOfString(" ", withString: "")
print("Token is \(token)")

Update for Swift 3

let deviceTokenString = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()

This is best solution : https://developer.android.com/studio/write/tool-attributes

This is design attributes we can set activty context in xml like

tools:context=".activity.ActivityName"

Adapter:

tools:context="com.PackegaName.AdapterName"

You can navigate to java class when clicking on the marked icon and tools have more features like

tools:text=""
tools:visibility:""
tools:listItems=""//for recycler view 

etx

Both of these are primary from the old printing days.

Carriage return is from the days of the teletype printers/old typewriters, where literally the carriage would return to the next line, and push the paper up. This is what we now call \r.

Line feed LF signals the end of the line, it signals that the line has ended - but doesn't move the cursor to the next line. In other words, it doesn't "return" the cursor/printer head to the next line.

For more sundry details, the mighty wikipedia to the rescue.

The spring docs are great on this: 3.8.1. BeanFactory or ApplicationContext?. They have a table with a comparison, I'll post a snippet:

Bean Factory

• Bean instantiation/wiring

Application Context

• Bean instantiation/wiring
• Automatic BeanPostProcessor registration
• Automatic BeanFactoryPostProcessor registration
• Convenient MessageSource access (for i18n)
• ApplicationEvent publication

So if you need any of the points presented on the Application Context side, you should use ApplicationContext.

You can use pathlib that is available in Python standard library 3.4 and above.

from pathlib import Path

files = [f for f in Path.cwd().iterdir() if f.match("145592*.jpg")]

Data can be pulled into an excel from another excel through Workbook method or External reference or through Data Import facility.

If you want to read or even if you want to update another excel workbook, these methods can be used. We may not depend only on VBA for this.

Dart http's implementation process the bytes thanks to that "charset=utf-8", so i'm sure several implementations out there supports this, to avoid the "latin-1" fallback charset when reading the bytes from the response. In my case, I totally lose format on the response body string, so I have to do the bytes encoding manually to utf8, or add that header "inner" parameter on my server's API response.

• Run

ng serve

This command run in your terminal after your in project folder location like ~/my-app$

• Then run the command - it will show the URl NG Live Development Server is listening on localhost:4200

• Open your browser on http://localhost:4200

CAREFUL: In the command in Lawakush Kurmi's answer (git tag -a v1.0) the -a flag is used. This flag tells Git to create an annotated flag. If you don't provide the flag (i.e. git tag v1.0) then it'll create what's called a lightweight tag.

Annotated tags are recommended, because they include a lot of extra information such as:

• the person who made the tag
• the date the tag was made
• a message for the tag

Because of this, you should always use annotated tags.

In the meantime, a time-window capability was added. See this link.

From manual page,

git-reset - Reset current HEAD to the specified state
git reset [-q] [<tree-ish>] [--] <paths>...
In the first and second form, copy entries from <tree-ish> to the index.

for example, when we use git reset HEAD~1 it reset our current HEAD to HEAD~1

so when we use git reset 'some-deleted-file-path'

git assume 'some-deleted-file-path' as some commit point and try to reset out current HEAD to there.

And it ends up fail

fatal: ambiguous argument 'some-deleted-file-path': unknown revision or path not in the working tree.

As Brannon says, it's OrderByDescending and ThenByDescending:

var query = from person in people
            orderby person.Name descending, person.Age descending
            select person.Name;

is equivalent to:

var query = people.OrderByDescending(person => person.Name)
                  .ThenByDescending(person => person.Age)
                  .Select(person => person.Name);

Here is the function which help you

private void saveBitmap(Bitmap bitmap,String path){
        if(bitmap!=null){
            try {
                FileOutputStream outputStream = null;
                try {
                    outputStream = new FileOutputStream(path); //here is set your file path where you want to save or also here you can set file object directly

Please check with the delegate method whether it is correct or not. For example;

-(void) tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath

for

-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath

To add to Blender's answer, you can disable SSL certificate validation for all requests using Session.verify = False

import requests

session = requests.Session()
session.verify = False
session.post(url='https://example.com', data={'bar':'baz'})

Note that urllib3, (which Requests uses), strongly discourages making unverified HTTPS requests and will raise an InsecureRequestWarning.

You are conflating Optional with having a default. An Optional accepts either a value or nil. Having a default permits the argument to be omitted in calling the function. An argument can have a default value with or without being of Optional type.

func someFunc(param1: String?,
          param2: String = "default value",
          param3: String? = "also has default value") {
    print("param1 = \(param1)")

    print("param2 = \(param2)")

    print("param3 = \(param3)")
}

Example calls with output:

someFunc(param1: nil, param2: "specific value", param3: "also specific value")

param1 = nil
param2 = specific value
param3 = Optional("also specific value")

someFunc(param1: "has a value")

param1 = Optional("has a value")
param2 = default value
param3 = Optional("also has default value")

someFunc(param1: nil, param3: nil)

param1 = nil
param2 = default value
param3 = nil

To summarize:

• Type with ? (e.g. String?) is an Optional may be nil or may contain an instance of Type
• Argument with default value may be omitted from a call to function and the default value will be used
• If both Optional and has default, then it may be omitted from function call OR may be included and can be provided with a nil value (e.g. param1: nil)
