works for me! :)

This is my answer (though I made it with jQuery but only for the purpose of selecting elements and to add and remove a class, so you can easily replace it with pure JS selectors & pure JS add attribute )

<input type='radio' name='radioBtn'>
<input type='radio' name='radioBtn'>
<input type='radio' name='radioBtn'>

$(document).on("click", "input[name='radioBtn']", function(){
    thisRadio = $(this);
    if (thisRadio.hasClass("imChecked")) {
        thisRadio.removeClass("imChecked");
        thisRadio.prop('checked', false);
    } else { 
        thisRadio.prop('checked', true);
        thisRadio.addClass("imChecked");
    };
})

I was able to do this by calling the DefaultIfEmpty() on the main model. This allowed me to left join on lazy loaded entities, seems more readable to me:

        var complaints = db.Complaints.DefaultIfEmpty()
            .Where(x => x.DateStage1Complete == null || x.DateStage2Complete == null)
            .OrderBy(x => x.DateEntered)
            .Select(x => new
            {
                ComplaintID = x.ComplaintID,
                CustomerName = x.Customer.Name,
                CustomerAddress = x.Customer.Address,
                MemberName = x.Member != null ? x.Member.Name: string.Empty,
                AllocationName = x.Allocation != null ? x.Allocation.Name: string.Empty,
                CategoryName = x.Category != null ? x.Category.Ssl_Name : string.Empty,
                Stage1Start = x.Stage1StartDate,
                Stage1Expiry = x.Stage1_ExpiryDate,
                Stage2Start = x.Stage2StartDate,
                Stage2Expiry = x.Stage2_ExpiryDate
            });

Suppose I have the following table T:

a   b
--------
1   abc
1   def
1   ghi
2   jkl
2   mno
2   pqr

And I do the following query:

SELECT a, b
FROM T
GROUP BY a

The output should have two rows, one row where a=1 and a second row where a=2.

But what should the value of b show on each of these two rows? There are three possibilities in each case, and nothing in the query makes it clear which value to choose for b in each group. It's ambiguous.

This demonstrates the single-value rule, which prohibits the undefined results you get when you run a GROUP BY query, and you include any columns in the select-list that are neither part of the grouping criteria, nor appear in aggregate functions (SUM, MIN, MAX, etc.).

Fixing it might look like this:

SELECT a, MAX(b) AS x
FROM T
GROUP BY a

Now it's clear that you want the following result:

a   x
--------
1   ghi
2   pqr

If you are pushing a new private image for the first time, make sure your subscription supports this extra image.

Docker allows you to have 6 private images named, even if you only pay for 5, but not to push that 6th image. The lack of an informative message is confusing and irritating.

Profiling shows that statement: std::copy() is always as fast as memcpy() or faster is false.

Red Alert pointed out that the code uses memcpy from array to array and std::copy from array to vector. That coud be a reason for faster memcpy.

Since there is

v.reserve(sizeof(arr1));

there shall be no difference in copy to vector or array.

The code is fixed to use array for both cases. memcpy still faster:

{
    time_t t = time(NULL);
    for(uint32_t i = 0; i < iterations; ++i)
        memcpy(arr1, arr2, sizeof(arr1));
    printf("memcpy()    elapsed %ld s\n", time(NULL) - t);
}

{
    time_t t = time(NULL);
    for(uint32_t i = 0; i < iterations; ++i)
        std::copy(arr1, arr1 + sizeof(arr1), arr2);
    printf("std::copy() elapsed %ld s\n", time(NULL) - t);
}

memcpy()    elapsed 44 s
std::copy() elapsed 48 s 

Yes, some how the ajax call aborted. The cause may be following.

1. Before completion of ajax request, user navigated to other page.
2. Ajax request have timeout.
3. Server is not able to return any response.

One thing to watch out for in benchmarks (especially phpbench.com), is even though the numbers are sound, the tests are not. Alot of the tests on phpbench.com are doing things at are trivial and abuse PHP's ability to cache array lookups to skew benchmarks or in the case of iterating over an array doesn't actually test it in real world cases (no one writes empty for loops). I've done my own benchmarks that I've found are fairly reflective of the real world results and they always show the language's native iterating syntax foreach coming out on top (surprise, surprise).

//make a nicely random array
$aHash1 = range( 0, 999999 );
$aHash2 = range( 0, 999999 );
shuffle( $aHash1 );
shuffle( $aHash2 );
$aHash = array_combine( $aHash1, $aHash2 );


$start1 = microtime(true);
foreach($aHash as $key=>$val) $aHash[$key]++;
$end1 = microtime(true);

$start2 = microtime(true);
while(list($key) = each($aHash)) $aHash[$key]++;
$end2 = microtime(true);


$start3 = microtime(true);
$key = array_keys($aHash);
$size = sizeOf($key);
for ($i=0; $i<$size; $i++) $aHash[$key[$i]]++;
$end3 = microtime(true);

$start4 = microtime(true);
foreach($aHash as &$val) $val++;
$end4 = microtime(true);

echo "foreach ".($end1 - $start1)."\n"; //foreach 0.947947025299

//For these tests we MUST do an array lookup,

If you want to pass two values, you can use this approach

<asp:LinkButton ID="RemoveFroRole" Text="Remove From Role" runat="server"
CommandName='<%# Eval("UserName") %>' CommandArgument='<%# Eval("RoleName") %>'
 OnClick="RemoveFromRole_Click" />

Basically I am treating {CommmandName,CommandArgument} as key value. Set both from database field. You will have to use OnClick event and use OnCommand event in this case, which I think is more clean code.

Summary.

Can I nest git repositories?

Yes. However, by default git does not track the .git folder of the nested repository. Git has features designed to manage nested repositories (read on).

Does it make sense to git init/add the /project_root to ease management of everything locally or do I have to manage my_project and the 3rd party one separately?

It probably doesn't make sense as git has features to manage nested repositories. Git's built in features to manage nested repositories are submodule and subtree.

Here is a blog on the topic and here is a SO question that covers the pros and cons of using each.

Apart from the excellent answers above I though I would write a C function that does not use any libraries and has some guards against bad strings.

uint8_t* datahex(char* string) {

    if(string == NULL) 
       return NULL;

    size_t slength = strlen(string);
    if((slength % 2) != 0) // must be even
       return NULL;

    size_t dlength = slength / 2;

    uint8_t* data = malloc(dlength);
    memset(data, 0, dlength);

    size_t index = 0;
    while (index < slength) {
        char c = string[index];
        int value = 0;
        if(c >= '0' && c <= '9')
          value = (c - '0');
        else if (c >= 'A' && c <= 'F') 
          value = (10 + (c - 'A'));
        else if (c >= 'a' && c <= 'f')
          value = (10 + (c - 'a'));
        else {
          free(data);
          return NULL;
        }

        data[(index/2)] += value << (((index + 1) % 2) * 4);

        index++;
    }

    return data;
}

Explanation:

a. index / 2 | Division between integers will round down the value, so 0/2 = 0, 1/2 = 0, 2/2 = 1, 3/2 = 1, 4/2 = 2, 5/2 = 2, etc. So, for every 2 string characters we add the value to 1 data byte.

b. (index + 1) % 2 | We want odd numbers to result to 1 and even to 0 since the first digit of a hex string is the most significant and needs to be multiplied by 16. so for index 0 => 0 + 1 % 2 = 1, index 1 => 1 + 1 % 2 = 0 etc.

c. << 4 | Shift by 4 is multiplying by 16. example: b00000001 << 4 = b00010000

If you can't just use filter join but need to perform some operations on the array's entry:

{% for entry in array %}
User {{ entry.attribute1 }} has id {{ entry.attribute2 }}
{% if not loop.last %}, {% endif %}
{% endfor %}

How to reset all data for a given URL / Website on Chrome Mobile for android:

1 - Open the Chrome menu, and tap on the "i (info)" icon

2 - tap "Site settings"

3 - Tap the trashcan icon

That's it, even the most deeply ensconsed service worker for that URL will now die.

Say, let we have column E filled by formulas that returns string, like:

= " = " & D7

where D7 cell consist more complicated formula, that composes final desired result, say:

= 3.02 * 1024 * 1024 * 1024

And so in all huge qty of rows that are.

When rows are a little - it just enough to copy desired cells as values (by RMB)
to nearest column, say G, and press F2 with following Enter in each of rows.
However, in case of huge qty of rows it's impossible ...

So, No VBA. No extra formulas. No F&R

No mistakes, no typo, but stupid mechanical actions instead only,

Like on a Ford conveyor. And in just a few seconds only:

1. [Assume, all of involved columns are in "General" format.]
2. Open Notepad++
3. Select entire column D
4. Ctrl+C
5. Ctrl+V in NPP
6. Ctrl+A in NPP
7. Select cell in the first row of desired column G1
8. Ctrl+V
9. Enjoy :) .

I think is not possible to do that. It would be a huge security risk if a browser access to that kind of personal information

Your code attempts to overwrite a string literal. This is undefined behaviour.

There are several ways to fix this:

1. use malloc() then strcpy() then free();
2. turn str into an array and use strcpy();
3. use strdup().

To close a windows form (System.Windows.Forms.Form) when one of its button is clicked: in Visual Studio, open the form in the designer, right click on the button and open its property page, then select the field DialogResult an set it to OK or the appropriate value.

The answer is You can't. Java (in your case JSP) is a server-side scripting language, which means that it is compiled and executed before all javascript code. You can assign javascript variables to JSP variables but not the other way around. If possible, you can have the variable appear in a QueryString or pass it via a form (through a hidden field), post it and extract the variable through JSP that way. But this would require resubmitting the page.

Hope this helps.

I have created a JSFiddle with my bindHTML knockout binding handler here: https://jsfiddle.net/glaivier/9859uq8t/

First, save the binding handler into its own (or a common) file and include after Knockout.

If you use this switch your bindings to this:

<div data-bind="bindHTML: htmlValue"></div>

OR

<!-- ko bindHTML: htmlValue --><!-- /ko -->

Use "%%". The man page describes this requirement:

% A '%' is written. No argument is converted. The complete conversion specification is '%%'.

See my new answer for the current version of SourceTree for Windows, 1.5.2.0. I'm leaving this answer behind for historical purposes.

Original Answer

as I'm on Windows I don't have a command line tool nor do I know how to use one :( Is it the only way to get that sorted out? The GUI doesn't cover all the git's functions? — Original Poster

Regarding Git GUIs, no, they don't cover all of Git's functions. They don't even come close. I suggest you check out one of the answers in How do I edit an incorrect commit message in Git?, Git is flexible enough that there are multiple solutions...from the command line.

SourceTree might actually come with the msysgit bash shell already, or it might be able to use the standard Windows command shell. Either way, you open it up form SourceTree by clicking the Terminal button:

You set which terminal SourceTree uses (bash or Windows) here:

That being said, here's one way you can do it in SourceTree. Since you mentioned in the comments that you don't mind "reverting back to the faulty commit" (by which I assume you actually mean resetting, which is a different operation in Git), then here are the steps:

1. Do a hard reset in SourceTree to the bad commit by right-clicking on it and selecting Reset current branch to this commit, and selecting the hard reset option from the drop down.
2. Click the Commit button, then
3. Click on the checkbox at the bottom that says "Amend latest commit".
4. Make the changes you want to the message, then click Commit again. Voila!

Regarding this comment:

if it's not possible because it's already pushed to Bitbucket, I would not mind creating a new repository and starting over.

Does this mean that you're the only person working on the repo? This is important because it's not trivial to change the history of a repo (like by amending a commit) without causing problems for your collaborators. However, assuming that you're the only person working on the repo, then the next thing you would want to do is force push your changed history to the remote.

Be aware, though, that because you did a hard reset to the faulty commit, then force pushing causes you to lose all work that come after it previously. If that's okay, then you might need to use the following command at the command line to do the force push, because I couldn't find an option to do it in SourceTree:

git push remote-repo head -f

This also assumes that BitBucket will allow you to force push to a repo.

You should really learn how to use Git from the command line anyways though, it'll make you more proficient in Git. #ProTip, use msysgit and turn on Quick Edit mode on in the terminal properties, so that you can double click to highlight a line of text, right click to copy, and right click again to paste. It's pretty quick.

I changed :

compile 'com.google.android.gms:play-services:9.0.0'

compile 'com.google.android.gms:play-services-auth:9.0.0'

to :

compile 'com.google.android.gms:play-services-maps:9.0.0'

compile 'com.google.android.gms:play-services-auth:9.0.0'

You can use jquery-validate.js . The following is the code snippet from jquery-validate.js.

// ajax mode: abort
// usage: $.ajax({ mode: "abort"[, port: "uniqueport"]});
// if mode:"abort" is used, the previous request on that port (port can be undefined) is aborted via XMLHttpRequest.abort()

var pendingRequests = {},
    ajax;
// Use a prefilter if available (1.5+)
if ( $.ajaxPrefilter ) {
    $.ajaxPrefilter(function( settings, _, xhr ) {
        var port = settings.port;
        if ( settings.mode === "abort" ) {
            if ( pendingRequests[port] ) {
                pendingRequests[port].abort();
            }
            pendingRequests[port] = xhr;
        }
    });
} else {
    // Proxy ajax
    ajax = $.ajax;
    $.ajax = function( settings ) {
        var mode = ( "mode" in settings ? settings : $.ajaxSettings ).mode,
            port = ( "port" in settings ? settings : $.ajaxSettings ).port;
        if ( mode === "abort" ) {
            if ( pendingRequests[port] ) {
                pendingRequests[port].abort();
            }
            pendingRequests[port] = ajax.apply(this, arguments);
            return pendingRequests[port];
        }
        return ajax.apply(this, arguments);
    };
}

So that you just only need to set the parameter mode to abort when you are making ajax request.

In my opinion, the laziest solution (especially if you don't rely on latest bleeding edge C/C++ features, or latest compiler features) wasn't mentioned yet, so here it is:

Just build on the system with the oldest GLIBC you still want to support.

This is actually pretty easy to do nowadays with technologies like chroot, or KVM/Virtualbox, or docker, even if you don't really want to use such an old distro directly on any pc. In detail, to make a maximum portable binary of your software I recommend following these steps:

1. Just pick your poison of sandbox/virtualization/... whatever, and use it to get yourself a virtual older Ubuntu LTS and compile with the gcc/g++ it has in there by default. That automatically limits your GLIBC to the one available in that environment.

2. Avoid depending on external libs outside of foundational ones: like, you should dynamically link ground-level system stuff like glibc, libGL, libxcb/X11/wayland things, libasound/libpulseaudio, possibly GTK+ if you use that, but otherwise preferrably statically link external libs/ship them along if you can. Especially mostly self-contained libs like image loaders, multimedia decoders, etc can cause less breakage on other distros (breakage can be caused e.g. if only present somewhere in a different major version) if you statically ship them.

With that approach you get an old-GLIBC-compatible binary without any manual symbol tweaks, without doing a fully static binary (that may break for more complex programs because glibc hates that, and which may cause licensing issues for you), and without setting up any custom toolchain, any custom glibc copy, or whatever.

All my services were running as expected, and I still couldn't connect.

I had to update the TCP/IP properties section in the SQL Server Configuration Manager for my SQL Server Express protocols, and set the IPALL port to 1433 in order to connect to the server as expected.

TESTED

import Vue from 'vue'
    
Vue.filter('formatYear', (value) => {
  if (!value) return ''
  return moment(value).format('YYYY')
})

I have found one related behaviour that may help (sounds like your specific problem runs deeper though):

Flash checks whether a source file needs recompiling by looking at timestamps. If its compiled version is older than the source file, it will recompile. But it doesn't check whether the compiled version was generated from the same source file or not.

Specifically, if you have your actionscript files under version control, and you Revert a change, the reverted file will usually have an older timestamp, and Flash will ignore it.

I had to solve a similar problem. I inherited a large source table from MS Access with nearly 15000 records that did not have a primary key, which I had to normalize and make CakePHP compatible. One convention of CakePHP is that every table has a the primary key, that it is first column and that it is called 'id'. The following simple statement did the trick for me under MySQL 5.5:

ALTER TABLE `database_name`.`table_name` 
ADD COLUMN `id` INT NOT NULL AUTO_INCREMENT FIRST,
ADD PRIMARY KEY (`id`);

This added a new column 'id' of type integer in front of the existing data ("FIRST" keyword). The AUTO_INCREMENT keyword increments the ids starting with 1. Now every dataset has a unique numerical id. (Without the AUTO_INCREMENT statement all rows are populated with id = 0).

I messed with this for several hours and tried many different suggestions.

I finally got it to work by doing the following:

Action: Start a program

Program/Script: C:\scriptdir\script.bat

Add arguments (optional) script.bat

Start in (optional): c:\scriptdir

run only when user logged in

run with highest privileges

configure for: Windows Vista, Windows Server 2008

Like so

DECLARE @t INT=1

SELECT CASE
            WHEN @t>0 THEN
                CASE
                    WHEN @t=1 THEN 'one'
                    ELSE 'not one'
                END
            ELSE 'less than one'
        END

EDIT: After looking more at the question, I think the best option is to create a function that calculates the value. That way, if you end up having multiple places where the calculation needs done, you only have one point to maintain the logic.

AND (both classes)

var list = document.getElementsByClassName("class1 class2");
var list = document.querySelectorAll(".class1.class2");

OR (at least one class)

var list = document.querySelectorAll(".class1,.class2");

XOR (one class but not the other)

var list = document.querySelectorAll(".class1:not(.class2),.class2:not(.class1)");

NAND (not both classes)

var list = document.querySelectorAll(":not(.class1),:not(.class2)");

NOR (not any of the two classes)

var list = document.querySelectorAll(":not(.class1):not(.class2)");

You should be able to use join, which joins on the index as default. Given your desired result, you must use outer as the join type.

>>> df1.join(df2, how='outer')
            V1  V2
A 1/1/2012  12  15
  2/1/2012  14 NaN
  3/1/2012 NaN  21
B 1/1/2012  15  24
  2/1/2012   8   9
C 1/1/2012  17 NaN
  2/1/2012   9 NaN
D 1/1/2012 NaN   7
  2/1/2012 NaN  16

Signature: _.join(other, on=None, how='left', lsuffix='', rsuffix='', sort=False) Docstring: Join columns with other DataFrame either on index or on a key column. Efficiently Join multiple DataFrame objects by index at once by passing a list.

I would suggest you have a look at the Spring Cloud Netflix Hystrix starter to handle potentially unreliable/slow remote calls. It implements the Circuit Breaker pattern, that is intended for precisely this sorta thing.

this will print 2-dimensional array as table.

First row will be header.

function array_to_table($table) 
{   
    echo "<table>";

    // Table header
    foreach ($table[0] as $header) {
      echo "<th>".$header."</th>";
    }

    // Table body
    $body = array_slice( $table, 1, null, true);
    foreach ($body as $row) {
      echo "<tr>";
        foreach ($row as $cell) {
          echo "<td>".$cell."</td>";
        } 
      echo "</tr>";
    }     
  echo "</table>";
}

usage:

arrayOfArrays = array(
    array('header1',"header2","header3"),
    array('1.1','1.2','1.3'),
    array('2.1','2.2','2.3'),
);


array_to_table($arrayOfArrays);

result:

<table><tbody><tr><th>header1</th><th>header2</th><th>header3/th><tr><td>1.1</td><td>1.2</td><td>1.3</td></tr><tr><td>2.1</td><td>2.2</td><td>2.3</td></tr><tr><td>3.1</td><td>3.2</td><td>3.3</td></tr></tbody></table>

You have the following solution from https://www.mkyong.com/java/java-how-to-compare-two-sets/

public static boolean equals(Set<?> set1, Set<?> set2){

    if(set1 == null || set2 ==null){
        return false;
    }

    if(set1.size() != set2.size()){
        return false;
    }

    return set1.containsAll(set2);
}

Or if you prefer to use a single return statement:

public static boolean equals(Set<?> set1, Set<?> set2){

  return set1 != null 
    && set2 != null 
    && set1.size() == set2.size() 
    && set1.containsAll(set2);
}

The answer, in a few words

In your example, itsProblem is a local variable.

Your must use self to set and get instance variables. You can set it in the __init__ method. Then your code would be:

class Example(object):
    def __init__(self):
        self.itsProblem = "problem"


theExample = Example()
print(theExample.itsProblem)

But if you want a true class variable, then use the class name directly:

class Example(object):
    itsProblem = "problem"


theExample = Example()
print(theExample.itsProblem)
print (Example.itsProblem)

But be careful with this one, as theExample.itsProblem is automatically set to be equal to Example.itsProblem, but is not the same variable at all and can be changed independently.

Some explanations

In Python, variables can be created dynamically. Therefore, you can do the following:

class Example(object):
    pass

Example.itsProblem = "problem"

e = Example()
e.itsSecondProblem = "problem"

print Example.itsProblem == e.itsSecondProblem 

prints

True

Therefore, that's exactly what you do with the previous examples.

Indeed, in Python we use self as this, but it's a bit more than that. self is the the first argument to any object method because the first argument is always the object reference. This is automatic, whether you call it self or not.

Which means you can do:

class Example(object):
    def __init__(self):
        self.itsProblem = "problem"


theExample = Example()
print(theExample.itsProblem)

or:

class Example(object):
    def __init__(my_super_self):
        my_super_self.itsProblem = "problem"


theExample = Example()
print(theExample.itsProblem)

It's exactly the same. The first argument of ANY object method is the current object, we only call it self as a convention. And you add just a variable to this object, the same way you would do it from outside.

Now, about the class variables.

When you do:

class Example(object):
    itsProblem = "problem"


theExample = Example()
print(theExample.itsProblem)

You'll notice we first set a class variable, then we access an object (instance) variable. We never set this object variable but it works, how is that possible?

Well, Python tries to get first the object variable, but if it can't find it, will give you the class variable. Warning: the class variable is shared among instances, and the object variable is not.

As a conclusion, never use class variables to set default values to object variables. Use __init__ for that.

Eventually, you will learn that Python classes are instances and therefore objects themselves, which gives new insight to understanding the above. Come back and read this again later, once you realize that.

For sending data to a service you can use:

Intent intent = new Intent(getApplicationContext(), YourService.class);
intent.putExtra("SomeData","ItValue");
startService(intent);

And after in service in onStartCommand() get data from intent.

For sending data or event from a service to an application (for one or more activities):

private void sendBroadcastMessage(String intentFilterName, int arg1, String extraKey) {
    Intent intent = new Intent(intentFilterName);
    if (arg1 != -1 && extraKey != null) {
        intent.putExtra(extraKey, arg1);
    }
    sendBroadcast(intent);
}

This method is calling from your service. You can simply send data for your Activity.

private void someTaskInYourService(){

    //For example you downloading from server 1000 files
    for(int i = 0; i < 1000; i++) {
        Thread.sleep(5000) // 5 seconds. Catch in try-catch block
        sendBroadCastMessage(Events.UPDATE_DOWNLOADING_PROGRESSBAR, i,0,"up_download_progress");
    }

For receiving an event with data, create and register method registerBroadcastReceivers() in your activity:

private void registerBroadcastReceivers(){
    broadcastReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            int arg1 = intent.getIntExtra("up_download_progress",0);
            progressBar.setProgress(arg1);
        }
    };
    IntentFilter progressfilter = new IntentFilter(Events.UPDATE_DOWNLOADING_PROGRESS);
    registerReceiver(broadcastReceiver,progressfilter);

For sending more data, you can modify method sendBroadcastMessage();. Remember: you must register broadcasts in onResume() & unregister in onStop() methods!

UPDATE

Please don't use my type of communication between Activity & Service. This is the wrong way. For a better experience please use special libs, such us:

1) EventBus from greenrobot

2) Otto from Square Inc

P.S. I'm only using EventBus from greenrobot in my projects,

val lines = scala.io.Source.fromFile("file.txt").mkString

By the way, "scala." isn't really necessary, as it's always in scope anyway, and you can, of course, import io's contents, fully or partially, and avoid having to prepend "io." too.

The above leaves the file open, however. To avoid problems, you should close it like this:

val source = scala.io.Source.fromFile("file.txt")
val lines = try source.mkString finally source.close()

Another problem with the code above is that it is horrible slow due to its implementation nature. For larger files one should use:

source.getLines mkString "\n"

In Chart.js version 2.0, it is possible to set labels for axes:

options = {
  scales: {
    yAxes: [{
      scaleLabel: {
        display: true,
        labelString: 'probability'
      }
    }]
  }     
}

See Labelling documentation for more details.

My scenario is when the user strikes the enter key while typing in textarea i have to include a line break.I achieved this using the below code......Hope it may helps somebody......

function CheckLength()
{
    var keyCode = event.keyCode
    if (keyCode == 13)
    {
        document.getElementById('ctl00_ContentPlaceHolder1_id_txt_Suggestions').value = document.getElementById('ctl00_ContentPlaceHolder1_id_txt_Suggestions').value + "\n<br>";
    }
}

From $http.get docs, the second parameter is a configuration object:

get(url, [config]);

Shortcut method to perform GET request.

You may change your code to:

$http.get('accept.php', {
    params: {
        source: link, 
        category_id: category
    }
});

Or:

$http({
    url: 'accept.php', 
    method: 'GET',
    params: { 
        source: link, 
        category_id: category
    }
});

As a side note, since Angular 1.6: .success should not be used anymore, use .then instead:

$http.get('/url', config).then(successCallback, errorCallback);

The correct answer to this particular questions is "don't select". Sometimes you have to select or activate, but 99% of the time you don't. If your code looks like

Select something
Do something to the selection
Select something else
Do something to the selection

You probably need to refactor and consider not selecting.

The error, Method 'Range' of object '_Worksheet' failed, error 1004, that you're getting is because the sheet with the button on it doesn't have a range named "Result". Most (maybe all) properties that return an object have a default Parent object. In this case, you're using the Range property to return a Range object. Because you don't qualify the Range property, Excel uses the default.

The default Parent object can be different based on the circumstances. If your code were in a standard module, then the ActiveSheet would be the default Parent and Excel would try to resolve ActiveSheet.Range("Result"). Your code is in a sheet's class module (the sheet with the button on it). When the unqualified reference is used there, the default Parent is the sheet that's attached to that module. In this case they're the same because the sheet has to be active to click the button, but that isn't always the case.

When Excel gives the error that includes text like '_Object' (yours said '_Worksheet') it's always referring to the default Parent object - the underscore gives that away. Generally the way to fix that is to qualify the reference by being explicit about the parent. But in the case of selecting and activating when you don't need to, it's better to just refactor the code.

Here's one way to write your code without any selecting or activating.

Private Sub cmdRecord_Click()

    Dim shSource As Worksheet
    Dim shDest As Worksheet
    Dim rNext As Range

    'Me refers to the sheet whose class module you're in
    'Me.Parent refers to the workbook
    Set shSource = Me.Parent.Worksheets("BxWsn Simulation")
    Set shDest = Me.Parent.Worksheets("Reslt Record")

    Set rNext = shDest.Cells(shDest.Rows.Count, 1).End(xlUp).Offset(1, 0)

    shSource.Range("Result").Copy
    rNext.PasteSpecial xlPasteFormulasAndNumberFormats

    Application.CutCopyMode = False

End Sub

When I'm in a class module, like the sheet's class module that you're working in, I always try to do things in terms of that class. So I use Me.Parent instead of ActiveWorkbook. It makes the code more portable and prevents unexpected problems when things change.

I'm sure the code you have now runs in milliseconds, so you may not care, but avoiding selecting will definitely speed up your code and you don't have to set ScreenUpdating. That may become important as your code grows or in a different situation.

Note that if variable is list of lists, some approaches would fail. For example:

v1 = [[range(3)] for x in range(4)]
v2 = v1[:3]+v1[4:] # this fails
v2

For the general case, use

removed_index = 1
v1 = [[range(3)] for x in range(4)]
v2 = [x for i,x in enumerate(v1) if x!=removed_index]
v2

simply you can use regex to trim all spaces or minify your array items

$array = array_map(function ($item) {
    return preg_replace('/\s+/', '', $item);
}, $array);

CSS properties should be set by cssText property or setAttribute method.

// Set multiple styles in a single statement
elt.style.cssText = "color: blue; border: 1px solid black"; 
// Or
elt.setAttribute("style", "color:red; border: 1px solid blue;");

Styles should not be set by assigning a string directly to the style property (as in elt.style = "color: blue;"), since it is considered read-only, as the style attribute returns a CSSStyleDeclaration object which is also read-only.

Unless I misunderstand your question, you can just open a file read only. Here is a simply example, without any checks.

To get the file path from the user use this function:

Private Function get_user_specified_filepath() As String
    'or use the other code example here.
    Dim fd As Office.FileDialog
    Set fd = Application.FileDialog(msoFileDialogFilePicker)
    fd.AllowMultiSelect = False
    fd.Title = "Please select the file."
    get_user_specified_filepath = fd.SelectedItems(1)
End Function

Then just open the file read only and assign it to a variable:

dim wb as workbook
set wb = Workbooks.Open(get_user_specified_filepath(), ReadOnly:=True)

This will put the results in tab delimited file(s) under a directory:

INSERT OVERWRITE LOCAL DIRECTORY '/home/hadoop/YourTableDir'
ROW FORMAT DELIMITED
FIELDS TERMINATED BY '\t'
STORED AS TEXTFILE
SELECT * FROM table WHERE id > 100;

It's quite interesting and makes me feel so powerful. :)

You can use directly replace function on javascript with regex or define a help function as in php ltrim(left) and rtrim(right):

1) With replace:

var myArray = ",'first string','more','even more'".replace(/^\s+/, '').split(/'?,?'/);

2) Help functions:

if (!String.prototype.ltrim) String.prototype.ltrim = function() {
    return this.replace(/^\s+/, '');
};
if (!String.prototype.rtrim) String.prototype.rtrim = function() {
    return this.replace(/\s+$/, '');
};
var myArray = ",'first string','more','even more'".ltrim().split(/'?,?'/).filter(function(el) {return el.length != 0});;

You can do and other things to add parameter to the help function with what you want to replace the char, etc.

You can do it with PHP:

header("Refresh:0");

It refreshes your current page, and if you need to redirect it to another page, use following:

header("Refresh:0; url=page2.php");

This will give you an array with 50 random numbers and display the smallest number in the array. I did it for an assignment in my programming class.

public static void main(String args[]) {
    // TODO Auto-generated method stub

    int i;
    int[] array = new int[50];
    for(i = 0; i <  array.length; i++) {
        array[i] = (int)(Math.random() * 100);
        System.out.print(array[i] + "  ");

        int smallest = array[0];

        for (i=1; i<array.length; i++)
        {
        if (array[i]<smallest)
        smallest = array[i];
        }



    }

}

}`

If you use IntelliJ IDEA you can browse all maven goals/tasks (including plugins) in Maven Projects tab:

objdump -T *.so may also do the job

placeBets(betList, stakeAmt) is an instance method not a static method. You need to create an instance of CBetfairAPI first:

MyBetfair api = new MyBetfair();
ArrayList bets = api.placeBets(betList, stakeAmt);

print "%02d"%a is the python 2 variant

python 3 uses a somewhat more verbose formatting system:

"{0:0=2d}".format(a)

The relevant doc link for python2 is: http://docs.python.org/2/library/string.html#format-specification-mini-language

For python3, it's http://docs.python.org/3/library/string.html#string-formatting

The easiest answer: jQuery. Do something like this:

$(document).ready(function(){
   var $form = $('form');
   $form.submit(function(){
      $.post($(this).attr('action'), $(this).serialize(), function(response){
            // do something here on success
      },'json');
      return false;
   });
});

If you want to add content dynamically and still need it to work, and also with more than one form, you can do this:

   $('form').live('submit', function(){
      $.post($(this).attr('action'), $(this).serialize(), function(response){
            // do something here on success
      },'json');
      return false;
   });

This is an addition to Josh's answer.

You can also keep the values of other variables while filtering out duplicated rows in data.table

Example:

library(data.table)

#create data table
dt <- data.table(
  V1=LETTERS[c(1,1,1,1,2,3,3,5,7,1)],
  V2=LETTERS[c(2,3,4,2,1,4,4,6,7,2)],
  V3=c(1),
  V4=c(2) )

> dt
# V1 V2 V3 V4
# A  B  1  2
# A  C  1  2
# A  D  1  2
# A  B  1  2
# B  A  1  2
# C  D  1  2
# C  D  1  2
# E  F  1  2
# G  G  1  2
# A  B  1  2

# set the key to all columns
setkey(dt)

# Get Unique lines in the data table
unique( dt[list(V1, V2), nomatch = 0] ) 

# V1 V2 V3 V4
# A  B  1  2
# A  C  1  2
# A  D  1  2
# B  A  1  2
# C  D  1  2
# E  F  1  2
# G  G  1  2

Alert: If there are different combinations of values in the other variables, then your result will be

unique combination of V1 and V2

Here is another non-regexp, non-super-awesome, non-super-optimized, however very easy to understand non-external-lib solution:

public static String trimStringByString(String text, String trimBy) {
    int beginIndex = 0;
    int endIndex = text.length();

    while (text.substring(beginIndex, endIndex).startsWith(trimBy)) {
        beginIndex += trimBy.length();
    } 

    while (text.substring(beginIndex, endIndex).endsWith(trimBy)) {
        endIndex -= trimBy.length();
    }

    return text.substring(beginIndex, endIndex);
}

Usage:

String trimmedString = trimStringByString(stringToTrim, "/");

I got this problem while using Bootstrap and I had multiple columns in each rows.

I was trying to give page-break-inside: avoid; or break-inside: avoid; to the col-md-6 div elements. That was not working.

I took a hint from the answers given above by DOK that floating elements do not work well with page-break-inside: avoid;.

Instead, I had to give page-break-inside: avoid; or break-inside: avoid; to the <div class="row"> element. And I had multiple rows in my print page.

That is, each row only had 2 columns in it. And they always fit horizontally and do not wrap on a new line.

In another example case, if you want 4 columns in each row, then use col-md-3.

Up until jQuery 1.11.1, you could use the following URLs to get the latest version of jQuery:

• https://code.jquery.com/jquery-latest.min.js - jQuery hosted (minified)
• https://code.jquery.com/jquery-latest.js - jQuery hosted (uncompressed)
• https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.min.js - Google hosted (minified)
• https://ajax.googleapis.com/ajax/libs/jquery/1/jquery.js - Google hosted (uncompressed)

For example:

<script src="https://code.jquery.com/jquery-latest.min.js"></script>

However, since jQuery 1.11.1, both jQuery and Google stopped updating these URL's; they will forever be fixed at 1.11.1. There is no supported alternative URL to use. For an explanation of why this is the case, see this blog post; Don't use jquery-latest.js.

Both hosts support https as well as http, so change the protocol as you see fit (or use a protocol relative URI)

Here goes:

char str[] = "This is the end";
char input[100];

printf("%s\n", str);
printf("%c\n", *str);

scanf("%99s", input);

There are 3 main ways to perform a case-insensitive search in Oracle without using full-text indexes.

Ultimately what method you choose is dependent on your individual circumstances; the main thing to remember is that to improve performance you must index correctly for case-insensitive searching.

1. Case your column and your string identically.

You can force all your data to be the same case by using UPPER() or LOWER():

select * from my_table where upper(column_1) = upper('my_string');

or

select * from my_table where lower(column_1) = lower('my_string');

If column_1 is not indexed on upper(column_1) or lower(column_1), as appropriate, this may force a full table scan. In order to avoid this you can create a function-based index.

create index my_index on my_table ( lower(column_1) );

If you're using LIKE then you have to concatenate a % around the string you're searching for.

select * from my_table where lower(column_1) LIKE lower('my_string') || '%';

This SQL Fiddle demonstrates what happens in all these queries. Note the Explain Plans, which indicate when an index is being used and when it isn't.

2. Use regular expressions.

From Oracle 10g onwards REGEXP_LIKE() is available. You can specify the _match_parameter_ 'i', in order to perform case-insensitive searching.

In order to use this as an equality operator you must specify the start and end of the string, which is denoted by the carat and the dollar sign.

select * from my_table where regexp_like(column_1, '^my_string$', 'i');

In order to perform the equivalent of LIKE, these can be removed.

select * from my_table where regexp_like(column_1, 'my_string', 'i');

Be careful with this as your string may contain characters that will be interpreted differently by the regular expression engine.

This SQL Fiddle shows you the same example output except using REGEXP_LIKE().

3. Change it at the session level.

The NLS_SORT parameter governs the collation sequence for ordering and the various comparison operators, including = and LIKE. You can specify a binary, case-insensitive, sort by altering the session. This will mean that every query performed in that session will perform case-insensitive parameters.

alter session set nls_sort=BINARY_CI

There's plenty of additional information around linguistic sorting and string searching if you want to specify a different language, or do an accent-insensitive search using BINARY_AI.

You will also need to change the NLS_COMP parameter; to quote:

The exact operators and query clauses that obey the NLS_SORT parameter depend on the value of the NLS_COMP parameter. If an operator or clause does not obey the NLS_SORT value, as determined by NLS_COMP, the collation used is BINARY.

The default value of NLS_COMP is BINARY; but, LINGUISTIC specifies that Oracle should pay attention to the value of NLS_SORT:

Comparisons for all SQL operations in the WHERE clause and in PL/SQL blocks should use the linguistic sort specified in the NLS_SORT parameter. To improve the performance, you can also define a linguistic index on the column for which you want linguistic comparisons.

So, once again, you need to alter the session

alter session set nls_comp=LINGUISTIC

As noted in the documentation you may want to create a linguistic index to improve performance

create index my_linguistc_index on my_table 
   (NLSSORT(column_1, 'NLS_SORT = BINARY_CI'));

You may want to try compiling with Facebook's HipHop.

For those who are looking for the shortest possible "item renderer" solution from a partial, so a combo of ng-repeat and ng-include:

<div ng-repeat="item in items" ng-include src="'views/partials/item.html'" />

Actually, if you use it like this for one repeater, it will work, but won't for 2 of them! Angular (v1.2.16) will freak out for some reason if you have 2 of these one after another, so it is safer to close the div the pre-xhtml way:

<div ng-repeat="item in items" ng-include src="'views/partials/item.html'"></div>

For the record an alternative approach might be to make the clickable layer the overlay: you make it semi-transparent and then place the "overlay" image behind it (somewhat counterintuitively, the "overlay" image could then be opaque). Depending on what you're trying to do, you might well be able to get the exact same visual effect (of an image and a clickable layer semi-transparently superimposed on top of each other), while avoiding clickability problems (because the "overlay" is in fact in the background).

JButton#isEnabled changes the user interactivity of a component, that is, whether a user is able to interact with it (press it) or not.

When a JButton is pressed, it fires a actionPerformed event.

You are receiving Add button is pressed when you press the confirm button because the add button is enabled. As stated, it has nothing to do with the pressed start of the button.

Based on you code, if you tried to check the "pressed" start of the add button within the confirm button's ActionListener it would always be false, as the button will only be in the pressed state while the add button's ActionListeners are being called.

Based on all this information, I would suggest you might want to consider using a JCheckBox which you can then use JCheckBox#isSelected to determine if it has being checked or not.

Take a closer look at How to Use Buttons for more details

I also wanted this and came up with this solution (I'm only using the date part - a default time makes no sense as a PropertyGrid default):

public class DefaultDateAttribute : DefaultValueAttribute {
  public DefaultDateAttribute(short yearoffset)
    : base(DateTime.Now.AddYears(yearoffset).Date) {
  }
}

This just creates a new attribute that you can add to your DateTime property. E.g. if it defaults to DateTime.Now.Date:

[DefaultDate(0)]

The top answers are correct. Please check them direct in MySQL CLI first. If this fixes the problem there, you may want to have it working in Python3 just pass it to the MySQLdb.connectas parameter

self.connection = MySQLdb.connect(
                    host=host, user=settings_DB.db_config['USER'],
                    port=port, passwd=settings_DB.db_config['PASSWORD'], 
                    db=settings_DB.db_config['NAME'],
                    local_infile=True)

1. Remove this line of code: For i = 1 To DatDiff. A For loop must have the word NEXT
2. Also, remove this line of code: StrSQL = StrSQL & "SELECT 'Test'" because its making Access look at your final SQL statement like this; INSERT INTO Test (Start_Date) VALUES ('" & InDate & "' );SELECT 'Test' Notice the semicolon in the middle of the SQL statement (should always be at the end. its by the way not required. you can also omit it). also, there is no space between the semicolon and the key word SELECT

in summary: remove those two lines of code above and your insert statement will work fine. You can the modify the code it later to suit your specific needs. And by the way, some times, you have to enclose dates in pounds signs like #

Here is a function I use to execute sql commands. You just have to change $sqlCommand.CommandText to the name of your sproc and $SqlCommand.CommandType to CommandType.StoredProcedure.

function execute-Sql{
    param($server, $db, $sql )
    $sqlConnection = new-object System.Data.SqlClient.SqlConnection
    $sqlConnection.ConnectionString = 'server=' + $server + ';integrated security=TRUE;database=' + $db 
    $sqlConnection.Open()
    $sqlCommand = new-object System.Data.SqlClient.SqlCommand
    $sqlCommand.CommandTimeout = 120
    $sqlCommand.Connection = $sqlConnection
    $sqlCommand.CommandText= $sql
    $text = $sql.Substring(0, 50)
    Write-Progress -Activity "Executing SQL" -Status "Executing SQL => $text..."
    Write-Host "Executing SQL => $text..."
    $result = $sqlCommand.ExecuteNonQuery()
    $sqlConnection.Close()
}

It depends on number of entities which are going to be updated, if you have large number of entities using JPA Query Update statement is better as you dont have to load all the entities from database, if you are going to update just one entity then using find and update is fine.

JSONObject responseDetailsJson = new JSONObject();
JSONArray jsonArray = new JSONArray();

List<String> ls =new  ArrayList<String>();

for(product cj:cities.getList()) {
    ls.add(cj);
    JSONObject formDetailsJson = new JSONObject();
    formDetailsJson.put("id", cj.id);
    formDetailsJson.put("name", cj.name);
    jsonArray.put(formDetailsJson);
}

responseDetailsJson.put("Cities", jsonArray);

return responseDetailsJson;

This is probably due to your target server not having a valid SSL certificate.

This problem might occur if you are behind corporate proxy and corporation uses its own certificate. Just add "--no-check-certificate" in the command. e.g. wget --no-check-certificate -qO - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add -

It works. If you want to see what is going on, you can use verbose command instead of quiet before adding "--no-check-certificate" option. e.g. wget -vO - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add - This will tell you to use "--no-check-certificate" if you are behind proxy.

Use py2exe.... use the below set up files:

from distutils.core import setup
import py2exe

from distutils.filelist import findall
import matplotlib

setup(
    console = ['PlotMemInfo.py'],

    options = {
        'py2exe': {
            'packages': ['matplotlib'],
            'dll_excludes': ['libgdk-win32-2.0-0.dll',
                             'libgobject-2.0-0.dll',
            'libgdk_pixbuf-2.0-0.dll']
        }
    },
    data_files = matplotlib.get_py2exe_datafiles()
)

It might be not direct solution, but I've created a lib that allows you to use 3 fingers touch instead of shake to open dev menu, when in development mode

https://github.com/pie6k/react-native-dev-menu-on-touch

You only have to wrap your app inside:

import DevMenuOnTouch from 'react-native-dev-menu-on-touch'; // or: import { DevMenuOnTouch } from 'react-native-dev-menu-on-touch'

class YourRootApp extends Component {
  render() {
    return (
      <DevMenuOnTouch>
        <YourApp />
      </DevMenuOnTouch>
    );
  }
}

It's really useful when you have to debug on real device and you have co-workers sitting next to you.

There is no documented LEFT() function in Oracle. Find the full set here.

Probably what you have is a user-defined function. You can check that easily enough by querying the data dictionary:

select * from all_objects
where object_name = 'LEFT'

But there is the question of why the stored procedure works and the query doesn't. One possible solution is that the stored procedure is owned by another schema, which also owns the LEFT() function. They have granted rights on the procedure but not its dependencies. This works because stored procedures run with DEFINER privileges by default, so you run the stored procedure as if you were its owner.

If this is so then the data dictionary query I listed above won't help you: it will only return rows for objects you have rights on. In which case you will need to run the query as the stored procedure's owner or connect as a user with the rights to query DBA_OBJECTS instead.

You can include this directly in your buttun. It works very well. I hope it'll be useful for you. onclick="setTimeout('location.href = ../../dashboard.xhtml;', 7000);"

Related answer, but if you want to run clean up a user inputting values into a form, here's what you can do:

const numFormatter = new Intl.NumberFormat('en-US', {
  style: "decimal",
  maximumFractionDigits: 2
})

// Good Inputs
parseFloat(numFormatter.format('1234').replace(/,/g,"")) // 1234
parseFloat(numFormatter.format('123').replace(/,/g,"")) // 123

// 3rd decimal place rounds to nearest
parseFloat(numFormatter.format('1234.233').replace(/,/g,"")); // 1234.23
parseFloat(numFormatter.format('1234.239').replace(/,/g,"")); // 1234.24

// Bad Inputs
parseFloat(numFormatter.format('1234.233a').replace(/,/g,"")); // NaN
parseFloat(numFormatter.format('$1234.23').replace(/,/g,"")); // NaN

// Edge Cases
parseFloat(numFormatter.format(true).replace(/,/g,"")) // 1
parseFloat(numFormatter.format(false).replace(/,/g,"")) // 0
parseFloat(numFormatter.format(NaN).replace(/,/g,"")) // NaN

Use the international date local via format. This cleans up any bad inputs, if there is one it returns a string of NaN you can check for. There's no way currently of removing commas as part of the locale (as of 10/12/19), so you can use a regex command to remove commas using replace.

ParseFloat converts the this type definition from string to number

If you use React, this is what your calculate function could look like:

updateCalculationInput = (e) => {
    let value;
    value = numFormatter.format(e.target.value); // 123,456.78 - 3rd decimal rounds to nearest number as expected
    if(value === 'NaN') return; // locale returns string of NaN if fail
    value = value.replace(/,/g, ""); // remove commas
    value = parseFloat(value); // now parse to float should always be clean input

    // Do the actual math and setState calls here
}

You are using the wrong format tokens when parsing your input. You should use ddd for an abbreviation of the name of day of the week, DD for day of the month, MMM for an abbreviation of the month's name, YYYY for the year, hh for the 1-12 hour, mm for minutes and A for AM/PM. See moment(String, String) docs.

Here is a working live sample:

console.log( moment('Mon 03-Jul-2017, 11:00 AM', 'ddd DD-MMM-YYYY, hh:mm A').format('hh:mm A') );_x000D_
console.log( moment('Mon 03-Jul-2017, 11:00 PM', 'ddd DD-MMM-YYYY, hh:mm A').format('hh:mm A') );

<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.18.1/moment.min.js"></script>

I encountered the same problem and solved it by

git checkout -f branch

and its specification is rather clear.

-f, --force

When switching branches, proceed even if the index or the working tree differs from HEAD. This is used to throw away local changes.

When checking out paths from the index, do not fail upon unmerged entries; instead, unmerged entries are ignored.

In most regex implementations (including Java's), : has no special meaning, neither inside nor outside a character class.

Your problem is most likely due to the fact the - acts as a range operator in your class:

[A-Za-z0-9.,-:]*

where ,-: matches all ascii characters between ',' and ':'. Note that it still matches the literal ':' however!

Try this instead:

[A-Za-z0-9.,:-]*

By placing - at the start or the end of the class, it matches the literal "-". As mentioned in the comments by Keoki Zee, you can also escape the - inside the class, but most people simply add it at the end.

A demo:

public class Test {
    public static void main(String[] args) {
        System.out.println("8:".matches("[,-:]+"));      // true: '8' is in the range ','..':'
        System.out.println("8:".matches("[,:-]+"));      // false: '8' does not match ',' or ':' or '-'
        System.out.println(",,-,:,:".matches("[,:-]+")); // true: all chars match ',' or ':' or '-'
    }
}

In my case , after I build hadoop on my 64 bit Linux mint OS, I replaced the native library in hadoop/lib. Still the problem persist. Then I figured out the hadoop pointing to hadoop/lib not to the hadoop/lib/native. So I just moved all content from native library to its parent. And the warning just gone.

Is there are more correct way?

Yes, there is.

LocalDate.now( 
    ZoneId.of( "America/Montreal" ) 
).atStartOfDay(
    ZoneId.of( "America/Montreal" )
)

java.time

Java 8 and later now has the new java.time framework built-in. See Tutorial. Inspired by Joda-Time, defined by JSR 310, and extended by the ThreeTen-Extra project.

Examples

Some examples follow, using java.time. Note how they specify a time zone. If omitted, your JVM’s current default time zone. That default can vary, even changing at any moment during runtime, so I suggest you specify a time zone explicitly rather than rely implicitly on the default.

Here is an example of date-only, without time-of-day nor time zone.

ZoneId zonedId = ZoneId.of( "America/Montreal" );
LocalDate today = LocalDate.now( zonedId );
System.out.println( "today : " + today );

today : 2015-10-19

Here is an example of getting current date-time.

ZoneId zonedId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.now( zonedId );
System.out.println( "zdt : " + zdt );

When run:

zdt : 2015-10-19T18:07:02.910-04:00[America/Montreal]

First Moment Of The Day

The Question asks for the date-time where the time is set to zero. This assumes the first moment of the day is always the time 00:00:00.0 but that is not always the case. Daylight Saving Time (DST) and perhaps other anomalies mean the day may begin at a different time such as 01:00.0.

Fortunately, java.time has a facility to determine the first moment of a day appropriate to a particular time zone, LocalDate::atStartOfDay. Let's see some code using the LocalDate named today and the ZoneId named zoneId from code above.

ZonedDateTime todayStart = today.atStartOfDay( zoneId );

zdt : 2015-10-19T00:00:00-04:00[America/Montreal]

Interoperability

If you must have a java.util.Date for use with classes not yet updated to work with the java.time types, convert. Call the java.util.Date.from( Instant instant ) method.

java.util.Date date = java.util.Date.from( zdt.toInstant() );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

It supports lists, but not as a separate data structure (ignoring arrays for the moment).

The for loop iterates over a list (in the generic sense) of white-space separated values, regardless of how that list is created, whether literally:

for i in 1 2 3; do
    echo "$i"
done

or via parameter expansion:

listVar="1 2 3"
for i in $listVar; do
    echo "$i"
done

or command substitution:

for i in $(echo 1; echo 2; echo 3); do
    echo "$i"
done

An array is just a special parameter which can contain a more structured list of value, where each element can itself contain whitespace. Compare the difference:

array=("item 1" "item 2" "item 3")
for i in "${array[@]}"; do   # The quotes are necessary here
    echo "$i"

(Additional step from solution above for if you are missing the AutoReconnect or Offline registry value)

For Visual Studio 2015, Version 14

1. Turn off all VS instances
2. HKEY_CURRENT_USER\SOFTWARE\Microsoft\VisualStudio\14.0\TeamFoundation\Instances{YourServerName}\Collections{TheCollectionName} (To get to this directory on Windows, hit the Windows + R key and search for "regedit")
3. Set both the Offline and AutoReconnect values to 0.
4. If you are missing one of those attributes (in my case I was missing AutoReconnect), right click and and create a new DWORD(32-bit) value with the desired missing name, AutoReconnect or Offline.
5. Again, make sure both values are set to zero.
6. Restart your solution

I had old MySQL and Centos OS (ver 6 I believe) that was not supported.
One day I couldn't access Plesk.
Using Filezilla, I copied files the database files from var/lib/mysql/databasename/ I then purchased a new server with new Centos 8 OS and MariaDB. In Plesk, I created a new database with the same name as my old one.
Using Filezilla, I then pasted the old database files into the newly created database folder. I could see the data in phpmyadmin but it was giving errors such as the ones described here. I happened to have an old sql backup dump file. I imported the dump file and it overwrote those files. I then pasted the old files back into var/lib/mysql/databasename/ I then had to do a repair in Plesk. To my suprise. It worked. I had over 6 months of order data restored and I didn't lose anything.

You can use pageX and pageY to get the position of the mouse in the window. You can also use jQuery's offset to get the position of an element.

So, it should be pageX - offset.left for how far from the left of the image and pageY - offset.top for how far from the top of the image.

Here is an example:

$(document).ready(function() {
  $('img').click(function(e) {
    var offset = $(this).offset();
    alert(e.pageX - offset.left);
    alert(e.pageY - offset.top);
  });
});

I've made a live example here and here is the source.

To calculate how far from the bottom or right, you would have to use jQuery's width and height methods.

Here is an handy solution! I'm using SQL Server 2008 R2.

As you want to modify the FK constraint by adding ON DELETE/UPDATE CASCADE, follow these steps:

NUMBER 1:

Right click on the constraint and click to Modify

NUMBER 2:

Choose your constraint on the left side (if there are more than one). Then on the right side, collapse "INSERT And UPDATE Specification" point and specify the actions on Delete Rule or Update Rule row to suit your need. After that, close the dialog box.

NUMBER 3:

The final step is to save theses modifications (of course!)

PS: It's saved me from a bunch of work as I want to modify a primary key referenced in another table.

If you're accessing this via a View then try sp_recompile or refreshing views.

sp_recompile:

Causes stored procedures, triggers, and user-defined functions to be recompiled the next time that they are run. It does this by dropping the existing plan from the procedure cache forcing a new plan to be created the next time that the procedure or trigger is run. In a SQL Server Profiler collection, the event SP:CacheInsert is logged instead of the event SP:Recompile.

Arguments

[ @objname= ] 'object'

The qualified or unqualified name of a stored procedure, trigger, table, view, or user-defined function in the current database. object is nvarchar(776), with no default. If object is the name of a stored procedure, trigger, or user-defined function, the stored procedure, trigger, or function will be recompiled the next time that it is run. If object is the name of a table or view, all the stored procedures, triggers, or user-defined functions that reference the table or view will be recompiled the next time that they are run.

Return Code Values

0 (success) or a nonzero number (failure)

Remarks

sp_recompile looks for an object in the current database only.

The queries used by stored procedures, or triggers, and user-defined functions are optimized only when they are compiled. As indexes or other changes that affect statistics are made to the database, compiled stored procedures, triggers, and user-defined functions may lose efficiency. By recompiling stored procedures and triggers that act on a table, you can reoptimize the queries.

try this method

private string removeNestedWhitespaces(char[] st)
{
    StringBuilder sb = new StringBuilder();
    int indx = 0, length = st.Length;
    while (indx < length)
    {
        sb.Append(st[indx]);
        indx++;
        while (indx < length && st[indx] == ' ')
            indx++;
        if(sb.Length > 1  && sb[0] != ' ')
            sb.Append(' ');
    }
    return sb.ToString();

use it like this:

string test = removeNestedWhitespaces("1 2 3  4    5".toCharArray());

Extra instructions when following @Luke-West's + @Vaiden's solutions:

• If your scheme has not changed (still showing my mac) on the top left next to the stop button:

1. Click NEWLY created Project name (next to stop button) > Click Edit Schemes > Build (left hand side) > Remove the old target (will say it's missing) and replace with the NEWLY named project under NEWLY named project logo

Also, I did not have to use step 3 of @Vaiden's solution. Just running rm -rf Pods/ in terminal got rid of all old pod files

I also did not have to use step 9 in @Vaiden's solution, instead I just removed the OLD project named framework under Link Binary Libraries (the NEWLY named framework was already there)

So the updated steps would be as follows:

Step 1 - Rename the project

0. If you are using cocoapods in your project, close the workspace, and open the XCode project for these steps.
1. Click on the project you want to rename in the "Project navigator" on the left of the Xcode view.
2. On the right select the "File inspector" and the name of your project should be in there under "Identity and Type", change it to the new name.
3. Click "Rename" in a dropdown menu

Step 2 - Rename the Scheme

1. In the top bar (near "Stop" button), there is a scheme for your OLD product, click on it, then go to "Manage schemes"
2. Click on the OLD name in the scheme, and it will become editable, change the name
3. Quit XCode.
4. In the master folder, rename OLD.xcworkspace to NEW.xcworkspace.

Step 3 - Rename the folder with your assets

1. Quit Xcode
2. In the correctly named master folder, there is a newly named xcodeproj file with the the wrongly named OLD folder. Rename the OLD folder to your new name
3. Reopen the project, you will see a warning: "The folder OLD does not exist", dismiss the warning
4. In the "Project navigator" on the left, click the top level OLD folder name
5. In Utilities pane under "Identity and type" you will see the "Name" entry, change this from the OLD to the new name
6. Just below there is a "Location" entry. Click on a folder with the OLD name and chose the newly renamed folder

Step 4 - Rename the Build plist data

1. Click on the project in the "Project navigator" on the left, in the main panel select "Build Settings"
2. Search for "plist" in this section Under packaging, you will see Info.plist, and Product bundle identifier
3. Rename the top entry in Info.plist
4. Do the same for Product Identifier

Step 5 Handling Podfile

1. In XCode: choose and edit Podfile from the project navigator. You should see a target clause with the OLD name. Change it to NEW.
2. Quit XCode.
3. In terminal, cd into project directory, then: pod deintegrate
4. Run pod install.
5. Open XCode.
6. Click on your project name in the project navigator.
7. In the main pane, switch to the Build Phases tab. Under Link Binary With Libraries, look for the OLD framework and remove it (should say it is missing) The NEWLY named framework should already be there, if not use the "+" button at the bottom of the window to add it
8. If you have an objective-c Bridging header go to Build settings and change the location of the header from OLD/OLD-Bridging-Header.h to NEW/NEW-Bridging-Header.h
9. Clean and run.

You should be able to build with no errors after you have followed all of the steps successfully

I posted some gist code (based on someone else's work which I note) that lets you properly authenticate against a self generated certificate (and how to get a free certificate - see comments bottom of Cocoanetics)

Use jQuery's IsNumeric method.

http://api.jquery.com/jQuery.isNumeric/

if ($.isNumeric(id)) {
   //it's numeric
}

CORRECTION: that would not ensure an integer. This would:

if ( (id+"").match(/^\d+$/) ) {
   //it's all digits
}

That, of course, doesn't use jQuery, but I assume jQuery isn't actually mandatory as long as the solution works

There are different ways we can pass the Access-Control-Expose-Headers.

• As jgauffin has explained we can create a new attribute.
• As LaundroMatt has explained we can add in the web.config file.

• Another way is we can add code as below in the webApiconfig.cs file.

  config.EnableCors(new EnableCorsAttribute("", headers: "", methods: "*",exposedHeaders: "TestHeaderToExpose") { SupportsCredentials = true });

Or we can add below code in the Global.Asax file.

protected void Application_BeginRequest()
        {
            if (HttpContext.Current.Request.HttpMethod == "OPTIONS")
            {
                //These headers are handling the "pre-flight" OPTIONS call sent by the browser
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Methods", "GET, POST, OPTIONS");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Headers", "*");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Credentials", "true");
                HttpContext.Current.Response.AddHeader("Access-Control-Allow-Origin", "http://localhost:4200");
                HttpContext.Current.Response.AddHeader("Access-Control-Expose-Headers", "TestHeaderToExpose");
                HttpContext.Current.Response.End();
            }
        }

I have written it for the options. Please modify the same as per your need.

Happy Coding !!

If you import the module (.py) file you are creating now from another python script it will not execute the code within

if __name__ == '__main__':
    ...

If you run the script directly from the console, it will be executed.

Python does not use or require a main() function. Any code that is not protected by that guard will be executed upon execution or importing of the module.

This is expanded upon a little more at python.berkely.edu

Chart.js is quite useful, supporting numerous other types of charts as well.

It can be used both with jQuery and without.

You have to traverse the whole array and keep two auxiliary values:

• The minimum value you find (on your way towards the end)
• The index of the place where you found the min value

Suppose your array is called myArray. At the end of this code minIndex has the index of the smallest value.

var min = Number.MAX_VALUE; //the largest number possible in JavaScript
var minIndex = -1;

for (int i=0; i<myArray.length; i++){
   if (myArray[i] < min){
      min = myArray[i];
      minIndex = i;
   }
}

This is assuming the worst case scenario: a totally random array. It is an O(n) algorithm or order n algorithm, meaning that if you have n elements in your array, then you have to look at all of them before knowing your answer. O(n) algorithms are the worst ones because they take a lot of time to solve the problem.

If your array is sorted or has any other specific structure, then the algorithm can be optimized to be faster.

Having said that, though, unless you have a huge array of thousands of values then don't worry about optimization since the difference between an O(n) algorithm and a faster one would not be noticeable.

Visitor

Visitor allows one to add new virtual functions to a family of classes without modifying the classes themselves; instead, one creates a visitor class that implements all of the appropriate specializations of the virtual function

Visitor structure:

Use Visitor pattern if:

1. Similar operations have to be performed on objects of different types grouped in a structure
2. You need to execute many distinct and unrelated operations. It separates Operation from objects Structure
3. New operations have to be added without change in object structure
4. Gather related operations into a single class rather than force you to change or derive classes
5. Add functions to class libraries for which you either do not have the source or cannot change the source

Even though Visitor pattern provides flexibility to add new operation without changing the existing code in Object, this flexibility has come with a drawback.

If a new Visitable object has been added, it requires code changes in Visitor & ConcreteVisitor classes. There is a workaround to address this issue : Use reflection, which will have impact on performance.

Code snippet:

import java.util.HashMap;

interface Visitable{
    void accept(Visitor visitor);
}

interface Visitor{
    void logGameStatistics(Chess chess);
    void logGameStatistics(Checkers checkers);
    void logGameStatistics(Ludo ludo);    
}
class GameVisitor implements Visitor{
    public void logGameStatistics(Chess chess){
        System.out.println("Logging Chess statistics: Game Completion duration, number of moves etc..");    
    }
    public void logGameStatistics(Checkers checkers){
        System.out.println("Logging Checkers statistics: Game Completion duration, remaining coins of loser");    
    }
    public void logGameStatistics(Ludo ludo){
        System.out.println("Logging Ludo statistics: Game Completion duration, remaining coins of loser");    
    }
}

abstract class Game{
    // Add game related attributes and methods here
    public Game(){

    }
    public void getNextMove(){};
    public void makeNextMove(){}
    public abstract String getName();
}
class Chess extends Game implements Visitable{
    public String getName(){
        return Chess.class.getName();
    }
    public void accept(Visitor visitor){
        visitor.logGameStatistics(this);
    }
}
class Checkers extends Game implements Visitable{
    public String getName(){
        return Checkers.class.getName();
    }
    public void accept(Visitor visitor){
        visitor.logGameStatistics(this);
    }
}
class Ludo extends Game implements Visitable{
    public String getName(){
        return Ludo.class.getName();
    }
    public void accept(Visitor visitor){
        visitor.logGameStatistics(this);
    }
}

public class VisitorPattern{
    public static void main(String args[]){
        Visitor visitor = new GameVisitor();
        Visitable games[] = { new Chess(),new Checkers(), new Ludo()};
        for (Visitable v : games){
            v.accept(visitor);
        }
    }
}

Explanation:

1. Visitable (Element) is an interface and this interface method has to be added to a set of classes.
2. Visitor is an interface, which contains methods to perform an operation on Visitable elements.
3. GameVisitor is a class, which implements Visitor interface ( ConcreteVisitor).
4. Each Visitable element accept Visitor and invoke a relevant method of Visitor interface.
5. You can treat Game as Element and concrete games like Chess,Checkers and Ludo as ConcreteElements.

In above example, Chess, Checkers and Ludo are three different games ( and Visitable classes). On one fine day, I have encountered with a scenario to log statistics of each game. So without modifying individual class to implement statistics functionality, you can centralise that responsibility in GameVisitor class, which does the trick for you without modifying the structure of each game.

output:

Logging Chess statistics: Game Completion duration, number of moves etc..
Logging Checkers statistics: Game Completion duration, remaining coins of loser
Logging Ludo statistics: Game Completion duration, remaining coins of loser

I had this happen repeatedly after adding images to a project in Eclipse and making them part of the build path. The solution was to right-click on the class containing the main method, and then choose Run As -> Java Application. It seems that when you add a file to the build path, Eclipse automatically assumes that file is where the main method is. By going through the Run As menu instead of just clicking the green Run As button, it allows you to specify the correct entry-point.

For top right corner try this:

position: absolute;
top: 0;
right: 0;

For me, i wanted my devl to be back to the master after it was ahead.

While on develop:

git checkout master
git pull

git checkout develop
git pull

git reset --hard origin/master
git push -f

If the file is large, you may not want to load it entirely into memory at once. This approach avoids that. (Of course, making a dict out of it could still take up some RAM, but it's guaranteed to be smaller than the original file.)

my_dict = {}
for i, line in enumerate(file):
    if (i - 8) % 7:
        continue
    k, v = line.split("\t")[:3:2]
    my_dict[k] = v

(pip maintainer here!)

If the package is not a wheel, pip tries to build a wheel for it (via setup.py bdist_wheel). If that fails for any reason, you get the "Failed building wheel for pycparser" message and pip falls back to installing directly (via setup.py install).

Once we have a wheel, pip can install the wheel by unpacking it correctly. pip tries to install packages via wheels as often as it can. This is because of various advantages of using wheels (like faster installs, cache-able, not executing code again etc).

Your error message here is due to the wheel package being missing, which contains the logic required to build the wheels in setup.py bdist_wheel. (pip install wheel can fix that.)

The above is the legacy behavior that is currently the default; we'll switch to PEP 517 by default, sometime in the future, moving us to a standards-based process for this. We also have isolated builds for that so, you'd have wheel installed in those environments by default. :)

• A blog post on "PEP 517 and 518 in Plain English"

The simplest method is to use LIKE:

SELECT CASE WHEN 'FDAJLK' LIKE '%[0-9]%' THEN 'True' ELSE 'False' END;  -- False
SELECT CASE WHEN 'FDAJ1K' LIKE '%[0-9]%' THEN 'True' ELSE 'False' END;  -- True

The following CSS changes in bold (plus a bunch of content in the columns to test scrolling) will work. See the result in this Pen.

.content { flex: 1; display: flex; height: 1px; }

.column { padding: 20px; border-right: 1px solid #999; overflow: auto; }

The trick seems to be that a scrollable panel needs to have a height literally set somewhere (in this case, via its parent), not just determined by flexbox. So even height: 1px works. The flex-grow:1 will still size the panel to fit properly.

If using a Mac

1. highlight column
2. copy
3. open terminal.app
4. type pbpaste|sort -u|wc -l

Linux users replace pbpaste with xclip xsel or similar

Here is how to make an authenticated POST request, using Refinery as an example:

# Copy the CSRF token "_csrf_token" and place it in the login request.
# Log in from the console to create a session
app.post '/community_members/login', {"authenticity_token"=>"gT7G17RNFaWUDLC6PJGapwHk/OEyYfI1V8yrlg0lHpM=",  "refinery_user[login]"=>'chloe', 'refinery_user[password]'=>'test'}
# View the session to verify CSRF token is the same
app.session.to_hash
# Copy the CSRF token "_csrf_token" and place it in the request. It's best to edit this in Notepad++
app.post '/refinery/blog/posts', {"authenticity_token"=>"gT7G17RNFaWUDLC6PJGapwHk/OEyYfI1V8yrlg0lHpM=", "switch_locale"=>"en", "post"=>{"title"=>"Test", "homepage"=>"0", "featured"=>"0", "magazine"=>"0", "refinery_category_ids"=>["1282"], "body"=>"Tests do a body good.", "custom_teaser"=>"", "draft"=>"0", "tag_list"=>"", "published_at(1i)"=>"2014", "published_at(2i)"=>"5", "published_at(3i)"=>"27", "published_at(4i)"=>"21", "published_at(5i)"=>"20", "custom_url"=>"", "source_url_title"=>"", "source_url"=>"", "user_id"=>"56", "browser_title"=>"", "meta_description"=>""}, "continue_editing"=>"false", "locale"=>:en}

You might find these useful too if you get an error:

app.cookies.to_hash
app.flash.to_hash
app.response # long, raw, HTML

Okay you got the syntax wrong here, correct way to do this is:

var arr: Criminal[] = [];

I'm assuming you are using var so that means declaring it somewhere inside the func(),my suggestion would be use let instead of var.

If declaring it as c class property usse acces modifiers like private, public, protected.

Update 1 November 2012

My original answer applies specifically to jQuery 1.6. My advice remains the same but jQuery 1.6.1 changed things slightly: in the face of the predicted pile of broken websites, the jQuery team reverted attr() to something close to (but not exactly the same as) its old behaviour for Boolean attributes. John Resig also blogged about it. I can see the difficulty they were in but still disagree with his recommendation to prefer attr().

Original answer

If you've only ever used jQuery and not the DOM directly, this could be a confusing change, although it is definitely an improvement conceptually. Not so good for the bazillions of sites using jQuery that will break as a result of this change though.

I'll summarize the main issues:

• You usually want prop() rather than attr().
• In the majority of cases, prop() does what attr() used to do. Replacing calls to attr() with prop() in your code will generally work.
• Properties are generally simpler to deal with than attributes. An attribute value may only be a string whereas a property can be of any type. For example, the checked property is a Boolean, the style property is an object with individual properties for each style, the size property is a number.
• Where both a property and an attribute with the same name exists, usually updating one will update the other, but this is not the case for certain attributes of inputs, such as value and checked: for these attributes, the property always represents the current state while the attribute (except in old versions of IE) corresponds to the default value/checkedness of the input (reflected in the defaultValue / defaultChecked property).
• This change removes some of the layer of magic jQuery stuck in front of attributes and properties, meaning jQuery developers will have to learn a bit about the difference between properties and attributes. This is a good thing.

If you're a jQuery developer and are confused by this whole business about properties and attributes, you need to take a step back and learn a little about it, since jQuery is no longer trying so hard to shield you from this stuff. For the authoritative but somewhat dry word on the subject, there's the specs: DOM4, HTML DOM, DOM Level 2, DOM Level 3. Mozilla's DOM documentation is valid for most modern browsers and is easier to read than the specs, so you may find their DOM reference helpful. There's a section on element properties.

As an example of how properties are simpler to deal with than attributes, consider a checkbox that is initially checked. Here are two possible pieces of valid HTML to do this:

<input id="cb" type="checkbox" checked>
<input id="cb" type="checkbox" checked="checked">

So, how do you find out if the checkbox is checked with jQuery? Look on Stack Overflow and you'll commonly find the following suggestions:

• if ( $("#cb").attr("checked") === true ) {...}
• if ( $("#cb").attr("checked") == "checked" ) {...}
• if ( $("#cb").is(":checked") ) {...}

This is actually the simplest thing in the world to do with the checked Boolean property, which has existed and worked flawlessly in every major scriptable browser since 1995:

if (document.getElementById("cb").checked) {...}

The property also makes checking or unchecking the checkbox trivial:

document.getElementById("cb").checked = false

In jQuery 1.6, this unambiguously becomes

$("#cb").prop("checked", false)

The idea of using the checked attribute for scripting a checkbox is unhelpful and unnecessary. The property is what you need.

• It's not obvious what the correct way to check or uncheck the checkbox is using the checked attribute
• The attribute value reflects the default rather than the current visible state (except in some older versions of IE, thus making things still harder). The attribute tells you nothing about the whether the checkbox on the page is checked. See http://jsfiddle.net/VktA6/49/.

You can do this:

<div class"my_class">
<?php if ($cart->count_product > 0) {
          print $cart->count_product; 
      } else { 
          print ''; 
      } 
?>
</div>

Before hitting the div, we are not in PHP tags

>>> df.groupby('id').first()
     value
id        
1    first
2    first
3    first
4   second
5    first
6    first
7   fourth

If you need id as column:

>>> df.groupby('id').first().reset_index()
   id   value
0   1   first
1   2   first
2   3   first
3   4  second
4   5   first
5   6   first
6   7  fourth

To get n first records, you can use head():

>>> df.groupby('id').head(2).reset_index(drop=True)
    id   value
0    1   first
1    1  second
2    2   first
3    2  second
4    3   first
5    3   third
6    4  second
7    4   fifth
8    5   first
9    6   first
10   6  second
11   7  fourth
12   7   fifth

According to the grammar in the CSP spec, you need to specify schemes as scheme:, not just scheme. So, you need to change the image source directive to:

img-src 'self' data:;

try table.Rows.add(row); after your for statement.

A simple solution would be to just write

this.date = new Date().toLocaleDateString();

date .toLocaleDateString() time .toLocaleTimeString() both .toLocaleString()

Hope this helps.

Some of these above answers didn't work for me but this did. Just in case someone else has the same issue.

The problem was that Linux paths are apparently case-sensitive so I had to rename my library files from "ckeditor.php" to "CKEditor.php".

I also changed my load call to match the capitalization:

$this->load->library('CKEditor');

It contains the allocated size, 10. The remaining indexes will contain the default value which is 0.

• Unique - Guarantees unique values for the column(or set of columns) included in the index
• Covering - Includes all of the columns that are used in a particular query (or set of queries), allowing the database to use only the index and not actually have to look at the table data to retrieve the results
• Clustered - This is way in which the actual data is ordered on the disk, which means if a query uses the clustered index for looking up the values, it does not have to take the additional step of looking up the actual table row for any data not included in the index.

SELECT
  b.name,
  MAX(b.value) as MaxValue,
  MAX(b.Anothercolumn) as AnotherColumn
FROM out_pumptabl
INNER JOIN (SELECT 
              name,
              MAX(value) as MaxValue
            FROM out_pumptabl
            GROUP BY Name) a ON 
  a.name = b.name AND a.maxValue = b.value
GROUP BY b.Name

Note this would be far easier if you had a primary key. Here is an Example

SELECT * FROM out_pumptabl c
WHERE PK in 
    (SELECT
      MAX(PK) as MaxPK
    FROM out_pumptabl b
    INNER JOIN (SELECT 
                  name,
                  MAX(value) as MaxValue
                FROM out_pumptabl
                GROUP BY Name) a ON 
      a.name = b.name AND a.maxValue = b.value) 

tl;dr What to do in modern (2018) times? Assume tel: is supported, use it and forget about anything else.

The tel: URI scheme RFC5431 (as well as sms: but also feed:, maps:, youtube: and others) is handled by protocol handlers (as mailto: and http: are).

They're unrelated to HTML5 specification (it has been out there from 90s and documented first time back in 2k with RFC2806) then you can't check for their support using tools as modernizr. A protocol handler may be installed by an application (for example Skype installs a callto: protocol handler with same meaning and behaviour of tel: but it's not a standard), natively supported by browser or installed (with some limitations) by website itself.

What HTML5 added is support for installing custom web based protocol handlers (with registerProtocolHandler() and related functions) simplifying also the check for their support through isProtocolHandlerRegistered() function.

There is some easy ways to determine if there is an handler or not:" How to detect browser's protocol handlers?).

In general what I suggest is:

1. If you're running on a mobile device then you can safely assume tel: is supported (yes, it's not true for very old devices but IMO you can ignore them).
2. If JS isn't active then do nothing.
3. If you're running on desktop browsers then you can use one of the techniques in the linked post to determine if it's supported.
4. If tel: isn't supported then change links to use callto: and repeat check desctibed in 3.
5. If tel: and callto: aren't supported (or - in a desktop browser - you can't detect their support) then simply remove that link replacing URL in href with javascript:void(0) and (if number isn't repeated in text span) putting, telephone number in title. Here HTML5 microdata won't help users (just search engines). Note that newer versions of Skype handle both callto: and tel:.

Please note that (at least on latest Windows versions) there is always a - fake - registered protocol handler called App Picker (that annoying window that let you choose with which application you want to open an unknown file). This may vanish your tests so if you don't want to handle Windows environment as a special case you can simplify this process as:

1. If you're running on a mobile device then assume tel: is supported.
2. If you're running on desktop then replace tel: with callto:. then drop tel: or leave it as is (assuming there are good chances Skype is installed).

If you are managing the Hibernate session manually, you may want to look into sessionFactory.getCurrentSession() and associated docs here:

http://www.hibernate.org/hib_docs/v3/reference/en/html/architecture-current-session.html

You need to join the two tables and then filter the result in where clause:

SELECT country.name as country, country.headofstate 
from country
inner join city on city.id = country.capital
where city.population > 100000
and country.headofstate like 'A%'

If you are using jQuery, you don't have to do anything special. Handlers added via $(document).ready() don't overwrite each other, but rather execute in turn:

$(document).ready(func1)
...
$(document).ready(func2)

If you are not using jQuery, you could use addEventListener, as demonstrated by Karaxuna, plus attachEvent for IE<9.

Note that onload is not equivalent to $(document).ready() - the former waits for CSS, images... as well, while the latter waits for the DOM tree only. Modern browsers (and IE since IE9) support the DOMContentLoaded event on the document, which corresponds to the jQuery ready event, but IE<9 does not.

if(window.addEventListener){
  window.addEventListener('load', func1)
}else{
  window.attachEvent('onload', func1)
}
...
if(window.addEventListener){
  window.addEventListener('load', func2)
}else{
  window.attachEvent('onload', func2)
}

If neither option is available (for example, you are not dealing with DOM nodes), you can still do this (I am using onload as an example, but other options are available for onload):

var oldOnload1=window.onload;
window.onload=function(){
  oldOnload1 && oldOnload1();
  func1();
}
...
var oldOnload2=window.onload;
window.onload=function(){
  oldOnload2 && oldOnload2();
  func2();
}

or, to avoid polluting the global namespace (and likely encountering namespace collisions), using the import/export IIFE pattern:

window.onload=(function(oldLoad){
  return function(){
    oldLoad && oldLoad();
    func1();
  }
})(window.onload)
...
window.onload=(function(oldLoad){
  return function(){
    oldLoad && oldLoad();
    func2();
  }
})(window.onload)

var fs = require("fs");
var filename = "./index.html";

function start(resp) {
    resp.writeHead(200, {
        "Content-Type": "text/html"
    });
    fs.readFile(filename, "utf8", function(err, data) {
        if (err) throw err;
        resp.write(data);
        resp.end();
    });
}

Debug.Print outputs to the "Immediate" window.

Also, you can simply type ? and then a statement directly into the immediate window (and then press Enter) and have the output appear right below, like this:

This can be very handy to quickly output the property of an object...

? myWidget.name

...to set the property of an object...

myWidget.name = "thingy"

...or to even execute a function or line of code, while in debugging mode:

Sheet1.MyFunction()

Add the same color of the background to the paragraph and then invert with CSS:

div {_x000D_
    background-color: #f00;_x000D_
}_x000D_
_x000D_
p { _x000D_
    color: #f00;_x000D_
    -webkit-filter: invert(100%);_x000D_
    filter: invert(100%);_x000D_
}

<div>_x000D_
    <p>inverted color</p>_x000D_
</div>

There is no need of jQuery to do that. You could code a jQuery wrapper but it would be useless so you should better use

var str = "Hello World";

window.alert("Starts with Hello ? " + /^Hello/i.test(str));        

window.alert("Ends with Hello ? " + /Hello$/i.test(str));

as the match() method is deprecated.

PS : the "i" flag in RegExp is optional and stands for case insensitive (so it will also return true for "hello", "hEllo", etc.).

To use IN, you must have a set, use this syntax instead:

SELECT * FROM Table1 WHERE Table1.principal NOT IN (SELECT principal FROM table2)

building on these answers - i also had to modify an X86 reference under Librarian -> Command Line -> Additional Options (for the x64 Platform)

Another thing you can do is to:

• create a property in your Item model that returns the category name and
• expose it as a ReadOnlyField.

Your model would look like this.

class Item(models.Model):
    name = models.CharField(max_length=100)
    category = models.ForeignKey(Category, related_name='items')

    def __unicode__(self):
        return self.name

    @property
    def category_name(self):
        return self.category.name

Your serializer would look like this. Note that the serializer will automatically get the value of the category_name model property by naming the field with the same name.

class ItemSerializer(serializers.ModelSerializer):
    category_name = serializers.ReadOnlyField()

    class Meta:
        model = Item

IN this answer when i say a file i mean the location in memory

All the data that is saved is stored in memory using a data structure called inodes Every inode has a inodenumber.The inode number is used to access the inode.All the hard links to a file may have different names but share the same inode number.Since all the hard links have the same inodenumber(which inturn access the same inode),all of them point to the same physical memory.

A symbolic link is a special kind of file.Since it is also a file it will have a file name and an inode number.As said above the inode number acceses an inode which points to data.Now what makes a symbolic link special is that the inodenumbers in symbolic links access those inodes which point to "a path" to another file.More specifically the inode number in symbolic link acceses those inodes who point to another hard link.

when we are moving,copying,deleting a file in GUI we are playing with the hardlinks of the file not the physical memory.when we delete a file we are deleting the hardlink of the file. we are not wiping out the physical memory.If all the hardlinks to file are deleted then it will not be possible to access the data stored although it may still be present in memory

Yes, according to the usual benchmarks. E.G : http://mckoss.com/jscript/SpeedTrial.htm.

But for the small strings, this is irrelevant. You will only care about performances on very large strings. What's more, in most JS script, the bottle neck is rarely on the string manipulations since there is not enough of it.

You'd better watch the DOM manipulation.

The button names are not submit, so the php $_POST['submit'] value is not set. As in isset($_POST['submit']) evaluates to false.

<html>
<form action="" method="post">
    <input type="hidden" name="action" value="submit" />
    <select name="name">
        <option>John</option>
        <option>Henry</option>
    <select>
<!-- 
make sure all html elements that have an ID are unique and name the buttons submit 
-->
    <input id="tea-submit" type="submit" name="submit" value="Tea">
    <input id="coffee-submit" type="submit" name="submit" value="Coffee">
</form>
</html>

<?php
if (isset($_POST['action'])) {
    echo '<br />The ' . $_POST['submit'] . ' submit button was pressed<br />';
}
?>

For 2 use cases:

1. I only want n overall results, not n results per file, the grep -m 2 is per file max occurrence.
2. I often use git grep which doesn't take -m

A good alternative in these scenarios is grep | sed 2q to grep first 2 occurrences across all files. sed documentation: https://www.gnu.org/software/sed/manual/sed.html

I bet this is what was intended as a result.

Please Note: The original poster was not specifically asking about PHP. All the php centric answers make large assumptions not relevant to the actual question.

The default error log as opposed to the scripts error logs usually has the (more) specific error. often it will be permissions denied or even an interpreter that can't be found.

This means the fault almost always lies with your script. e.g you uploaded a perl script but didnt give it execute permissions? or perhaps it was corrupted in a linux environment if you write the script in windows and then upload it to the server without the line endings being converted you will get this error.

in perl if you forget

print "content-type: text/html\r\n\r\n";

you will get this error

There are many reasons for it. so please first check your error log and then provide some more information.

The default error log is often in /var/log/httpd/error_log or /var/log/apache2/error.log.

The reason you look at the default error logs (as indicated above) is because errors don't always get posted into the custom error log as defined in the virtual host.

Assumes linux and not necessarily perl

    1 console.log(new Date())
    2. document.getElementById("date").valueAsDate = new Date();

1st log showing correct in console =Wed Oct 07 2020 00:40:54 GMT+0530 (India Standard Time)

2nd 06-10-2020 which is incorrect and today date is 07 and here showing 06.

This post asked a similar question and used LINQ to solve it, maybe it will help you out too.

string s1 = "1;2;3;4;5;6;7;8;9;10;11;12";
int[] ia = s1.Split(';').Select(n => Convert.ToInt32(n)).ToArray();

For developers looking for a full-featured geolocation utility, you can have a look at geolocator.js (I'm the author).

Example below will first try HTML5 Geolocation API to obtain the exact coordinates. If fails or rejected, it will fallback to Geo-IP look-up. Once it gets the coordinates, it will reverse-geocode the coordinates into an address.

var options = {
    enableHighAccuracy: true,
    timeout: 6000,
    maximumAge: 0,
    desiredAccuracy: 30,
    fallbackToIP: true, // if HTML5 geolocation fails or rejected
    addressLookup: true, // get detailed address information
    timezone: true, 
    map: "my-map" // this will even create a map for you
};

geolocator.locate(options, function (err, location) {
    console.log(err || location);
});

It supports geo-location (via HTML5 or IP lookups), geocoding, address look-ups (reverse geocoding), distance & durations, timezone information and more...

In Xcode 4

- Product menu > Manage Schemes
- Select the scheme thats having debugging problems (if only one choose that)
- Click Edit button at bottom
- Edit Scheme dialog appears
- in left panel click on Run APPNAME.app
- on Right hand panel make sure youre on INFO tab
- look for drop down DEBUGGER:
- someone had set this to None
- set to LLDB if this is your preferred debugger
- can also change BUILD CONFIGURATION drop down to Debug 
-      but I have other targets set to AdHoc which debug fine once Debugger is set

You can call this function in beforeMount section of a Vue component: like following:

 ....
 methods:{
     getUnits: function() {...}
 },
 beforeMount(){
    this.getUnits()
 },
 ......

Working fiddle: https://jsfiddle.net/q83bnLrx/1/

There are different lifecycle hooks Vue provide:

I have listed few are :

1. beforeCreate: Called synchronously after the instance has just been initialized, before data observation and event/watcher setup.
2. created: Called synchronously after the instance is created. At this stage, the instance has finished processing the options which means the following have been set up: data observation, computed properties, methods, watch/event callbacks. However, the mounting phase has not been started, and the $el property will not be available yet.
3. beforeMount: Called right before the mounting begins: the render function is about to be called for the first time.
4. mounted: Called after the instance has just been mounted where el is replaced by the newly created vm.$el.
5. beforeUpdate: Called when the data changes, before the virtual DOM is re-rendered and patched.
6. updated: Called after a data change causes the virtual DOM to be re-rendered and patched.

You can have a look at complete list here.

You can choose which hook is most suitable to you and hook it to call you function like the sample code provided above.

A solution to ensure that images don't get cut when printed in a Web page is to have the following CSS rule:

@media print { 
  img { 
    max-width:100% !important;
  } 
}

elem.classList.add("first");
elem.classList.add("second");
elem.classList.add("third");

is equal

elem.classList.add("first","second","third");

You can also use DateTime class:

$time1 = new DateTime('09:00:59');
$time2 = new DateTime('09:01:00');
$interval = $time1->diff($time2);
echo $interval->format('%s second(s)');

Result:

1 second(s)

Try this:

CSS

.style1{
    background-color:red;
    color:white;
    font-size:44px;
}

HTML

<div id="foo">hello world!</div>
<img src="zoom.png" onclick="myFunction()" />

Javascript

function myFunction()
{
    document.getElementById('foo').setAttribute("class", "style1");
}

df[df.columns[i]]

where i is the position/number of the column(starting from 0).

So, i = 0 is for the first column.

You can also get the last column using i = -1

Jacob's reply to John T works perfectly to delete the whole line, and you can Find in Files with that. Make sure to check "Regular expression" at bottom.

Solution: ^.*#region.*$

What fixed it for me was disabling Git by setting Current source control plug-in to None in Visual Studio, menu Options → Source Control:

For any T object you can do:

return Request.CreateResponse<T>(HttpStatusCode.OK, Tobject);

Below example may help,

int main(void)
{
    double **a2d = new double*[5]; 
    /* initializing Number of rows, in this case 5 rows) */
    for (int i = 0; i < 5; i++)
    {
        a2d[i] = new double[3]; /* initializing Number of columns, in this case 3 columns */
    }

    for (int i = 0; i < 5; i++)
    {
        for (int j = 0; j < 3; j++)
        {
            a2d[i][j] = 1; /* Assigning value 1 to all elements */
        }
    }

    for (int i = 0; i < 5; i++)
    {
        for (int j = 0; j < 3; j++)
        {
            cout << a2d[i][j] << endl;  /* Printing all elements to verify all elements have been correctly assigned or not */
        }
    }

    for (int i = 0; i < 5; i++)
        delete[] a2d[i];

    delete[] a2d;


    return 0;
}

I've used the following method to detect if a string contains only whitespace. It also matches empty strings.

if (/^\s*$/.test(myStr)) {
  // the string contains only whitespace
}

If you're having an issue where the Resources added are images and are not getting copied to your build folder on compiling. You need to change the "Build Action" to None from Resource ( which is the default) and change the Copy to "If Newer" or "Always" as shown below :

const express = require('express')
const app = express()
const port = 3000

app.get('/', (req, res) => res.send('Hello World!'))

app.listen(port, () => console.log(`Example app listening on port ${port}!`))

TL;DR

mysql_real_escape_string() will provide no protection whatsoever (and could furthermore munge your data) if:

• MySQL's NO_BACKSLASH_ESCAPES SQL mode is enabled (which it might be, unless you explicitly select another SQL mode every time you connect); and

• your SQL string literals are quoted using double-quote " characters.

This was filed as bug #72458 and has been fixed in MySQL v5.7.6 (see the section headed "The Saving Grace", below).

This is another, (perhaps less?) obscure EDGE CASE!!!

In homage to @ircmaxell's excellent answer (really, this is supposed to be flattery and not plagiarism!), I will adopt his format:

The Attack

Starting off with a demonstration...

mysql_query('SET SQL_MODE="NO_BACKSLASH_ESCAPES"'); // could already be set
$var = mysql_real_escape_string('" OR 1=1 -- ');
mysql_query('SELECT * FROM test WHERE name = "'.$var.'" LIMIT 1');

This will return all records from the test table. A dissection:

1. Selecting an SQL Mode

   mysql_query('SET SQL_MODE="NO_BACKSLASH_ESCAPES"');
   

   As documented under String Literals:

   There are several ways to include quote characters within a string:

   • A “'” inside a string quoted with “'” may be written as “''”.

   • A “"” inside a string quoted with “"” may be written as “""”.

   • Precede the quote character by an escape character (“\”).

   • A “'” inside a string quoted with “"” needs no special treatment and need not be doubled or escaped. In the same way, “"” inside a string quoted with “'” needs no special treatment.

   If the server's SQL mode includes NO_BACKSLASH_ESCAPES, then the third of these options—which is the usual approach adopted by mysql_real_escape_string()—is not available: one of the first two options must be used instead. Note that the effect of the fourth bullet is that one must necessarily know the character that will be used to quote the literal in order to avoid munging one's data.

2. The Payload

   " OR 1=1 -- 
   

   The payload initiates this injection quite literally with the " character. No particular encoding. No special characters. No weird bytes.

3. mysql_real_escape_string()

   $var = mysql_real_escape_string('" OR 1=1 -- ');
   

   Fortunately, mysql_real_escape_string() does check the SQL mode and adjust its behaviour accordingly. See libmysql.c:

   ulong STDCALL
   mysql_real_escape_string(MYSQL *mysql, char *to,const char *from,
                ulong length)
   {
     if (mysql->server_status & SERVER_STATUS_NO_BACKSLASH_ESCAPES)
       return escape_quotes_for_mysql(mysql->charset, to, 0, from, length);
     return escape_string_for_mysql(mysql->charset, to, 0, from, length);
   }
   

   Thus a different underlying function, escape_quotes_for_mysql(), is invoked if the NO_BACKSLASH_ESCAPES SQL mode is in use. As mentioned above, such a function needs to know which character will be used to quote the literal in order to repeat it without causing the other quotation character from being repeated literally.

   However, this function arbitrarily assumes that the string will be quoted using the single-quote ' character. See charset.c:

   /*
     Escape apostrophes by doubling them up
   
   // [ deletia 839-845 ]
   
     DESCRIPTION
       This escapes the contents of a string by doubling up any apostrophes that
       it contains. This is used when the NO_BACKSLASH_ESCAPES SQL_MODE is in
       effect on the server.
   
   // [ deletia 852-858 ]
   */
   
   size_t escape_quotes_for_mysql(CHARSET_INFO *charset_info,
                                  char *to, size_t to_length,
                                  const char *from, size_t length)
   {
   // [ deletia 865-892 ]
   
       if (*from == '\'')
       {
         if (to + 2 > to_end)
         {
           overflow= TRUE;
           break;
         }
         *to++= '\'';
         *to++= '\'';
       }
   

   So, it leaves double-quote " characters untouched (and doubles all single-quote ' characters) irrespective of the actual character that is used to quote the literal! In our case $var remains exactly the same as the argument that was provided to mysql_real_escape_string()—it's as though no escaping has taken place at all.

4. The Query

   mysql_query('SELECT * FROM test WHERE name = "'.$var.'" LIMIT 1');
   

   Something of a formality, the rendered query is:

   SELECT * FROM test WHERE name = "" OR 1=1 -- " LIMIT 1
   

As my learned friend put it: congratulations, you just successfully attacked a program using mysql_real_escape_string()...

The Bad

mysql_set_charset() cannot help, as this has nothing to do with character sets; nor can mysqli::real_escape_string(), since that's just a different wrapper around this same function.

The problem, if not already obvious, is that the call to mysql_real_escape_string() cannot know with which character the literal will be quoted, as that's left to the developer to decide at a later time. So, in NO_BACKSLASH_ESCAPES mode, there is literally no way that this function can safely escape every input for use with arbitrary quoting (at least, not without doubling characters that do not require doubling and thus munging your data).

The Ugly

It gets worse. NO_BACKSLASH_ESCAPES may not be all that uncommon in the wild owing to the necessity of its use for compatibility with standard SQL (e.g. see section 5.3 of the SQL-92 specification, namely the <quote symbol> ::= <quote><quote> grammar production and lack of any special meaning given to backslash). Furthermore, its use was explicitly recommended as a workaround to the (long since fixed) bug that ircmaxell's post describes. Who knows, some DBAs might even configure it to be on by default as means of discouraging use of incorrect escaping methods like addslashes().

Also, the SQL mode of a new connection is set by the server according to its configuration (which a SUPER user can change at any time); thus, to be certain of the server's behaviour, you must always explicitly specify your desired mode after connecting.

The Saving Grace

So long as you always explicitly set the SQL mode not to include NO_BACKSLASH_ESCAPES, or quote MySQL string literals using the single-quote character, this bug cannot rear its ugly head: respectively escape_quotes_for_mysql() will not be used, or its assumption about which quote characters require repeating will be correct.

For this reason, I recommend that anyone using NO_BACKSLASH_ESCAPES also enables ANSI_QUOTES mode, as it will force habitual use of single-quoted string literals. Note that this does not prevent SQL injection in the event that double-quoted literals happen to be used—it merely reduces the likelihood of that happening (because normal, non-malicious queries would fail).

In PDO, both its equivalent function PDO::quote() and its prepared statement emulator call upon mysql_handle_quoter()—which does exactly this: it ensures that the escaped literal is quoted in single-quotes, so you can be certain that PDO is always immune from this bug.

As of MySQL v5.7.6, this bug has been fixed. See change log:

Functionality Added or Changed

• Incompatible Change: A new C API function, mysql_real_escape_string_quote(), has been implemented as a replacement for mysql_real_escape_string() because the latter function can fail to properly encode characters when the NO_BACKSLASH_ESCAPES SQL mode is enabled. In this case, mysql_real_escape_string() cannot escape quote characters except by doubling them, and to do this properly, it must know more information about the quoting context than is available. mysql_real_escape_string_quote() takes an extra argument for specifying the quoting context. For usage details, see mysql_real_escape_string_quote().

   Note

  Applications should be modified to use mysql_real_escape_string_quote(), instead of mysql_real_escape_string(), which now fails and produces an CR_INSECURE_API_ERR error if NO_BACKSLASH_ESCAPES is enabled.

Safe Examples

Taken together with the bug explained by ircmaxell, the following examples are entirely safe (assuming that one is either using MySQL later than 4.1.20, 5.0.22, 5.1.11; or that one is not using a GBK/Big5 connection encoding):

mysql_set_charset($charset);
mysql_query("SET SQL_MODE=''");
$var = mysql_real_escape_string('" OR 1=1 /*');
mysql_query('SELECT * FROM test WHERE name = "'.$var.'" LIMIT 1');

...because we've explicitly selected an SQL mode that doesn't include NO_BACKSLASH_ESCAPES.

mysql_set_charset($charset);
$var = mysql_real_escape_string("' OR 1=1 /*");
mysql_query("SELECT * FROM test WHERE name = '$var' LIMIT 1");

...because we're quoting our string literal with single-quotes.

$stmt = $pdo->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$stmt->execute(["' OR 1=1 /*"]);

...because PDO prepared statements are immune from this vulnerability (and ircmaxell's too, provided either that you're using PHP=5.3.6 and the character set has been correctly set in the DSN; or that prepared statement emulation has been disabled).

$var  = $pdo->quote("' OR 1=1 /*");
$stmt = $pdo->query("SELECT * FROM test WHERE name = $var LIMIT 1");

...because PDO's quote() function not only escapes the literal, but also quotes it (in single-quote ' characters); note that to avoid ircmaxell's bug in this case, you must be using PHP=5.3.6 and have correctly set the character set in the DSN.

$stmt = $mysqli->prepare('SELECT * FROM test WHERE name = ? LIMIT 1');
$param = "' OR 1=1 /*";
$stmt->bind_param('s', $param);
$stmt->execute();

...because MySQLi prepared statements are safe.

Wrapping Up

Thus, if you:

• use native prepared statements

OR

• use MySQL v5.7.6 or later

OR

• in addition to employing one of the solutions in ircmaxell's summary, use at least one of:

  • PDO;
  • single-quoted string literals; or
  • an explicitly set SQL mode that does not include NO_BACKSLASH_ESCAPES

...then you should be completely safe (vulnerabilities outside the scope of string escaping aside).

Looking at the code always helps too. That is, you can actually take a look at the generated partial class (that calls LoadComponent) by doing the following:

1. Go to the Solution Explorer pane in the Visual Studio solution that you are interested in.
2. There is a button in the tool bar of the Solution Explorer titled 'Show All Files'. Toggle that button.
3. Now, expand the obj folder and then the Debug or Release folder (or whatever configuration you are building) and you will see a file titled YourClass.g.cs.

The YourClass.g.cs ... is the code for generated partial class. Again, if you open that up you can see the InitializeComponent method and how it calls LoadComponent ... and much more.

Once upon a time, people had terminals like typewriters (with only upper-case letters, but that's another story). Search for 'Teletype', and how do you think tty got used for 'terminal device'?

Those devices had two separate motions. The carriage return moved the print head back to the start of the line without scrolling the paper; the line feed character moved the paper up a line without moving the print head back to the beginning of the line. So, on those devices, you needed two control characters to get the print head back to the start of the next line: a carriage return and a line feed. Because this was mechanical, it took time, so you had to pause for long enough before sending more characters to the terminal after sending the CR and LF characters. One use for CR without LF was to do 'bold' by overstriking the characters on the line. You'd write the line out once, then use CR to start over and print twice over the characters that needed to be bold. You could also, of course, type X's over stuff that you wanted partially hidden, or create very dense ASCII art pictures with judicious overstriking.

On Unix, all the logic for this stuff was hidden in a terminal driver. You could use the stty command and the underlying functions (in those days, ioctl() calls; they were sanitized into the termios interface by POSIX.1 in 1988) to tweak all sorts of ways that the terminal behaved.

Eventually, you got 'glass terminals' where the speeds were greater and and there were new idiosyncrasies to deal with - Hazeltine glitches and so on and so forth. These got enshrined in the termcap and later terminfo libraries, and then further encapsulated behind the curses library.

However, some other (non-Unix) systems did not hide things as well, and you had to deal with CRLF in your text files - and no, this is not just Windows and DOS that were in the 'CRLF' camp.

Anyway, on some systems, the C library has to deal with text files that contain CRLF line endings and presents those to you as if there were only a newline at the end of the line. However, if you choose to treat the text file as a binary file, you will see the CR characters as well as the LF.

Systems like the old Mac OS (version 9 or earlier) used just CR (aka \r) for the line ending. Systems like DOS and Windows (and, I believe, many of the DEC systems such as VMS and RSTS) used CRLF for the line ending. Many of the Internet standards (such as mail) mandate CRLF line endings. And Unix has always used just LF (aka NL or newline, hence \n) for its line endings. And most people, most of the time, manage to ignore CR.

Your code is rather funky in looking for \r. On a system compliant with the C standard, you won't see the CR unless the file is opened in binary mode; the CRLF or CR will be mapped to NL by the C runtime library.

Sure you can:

SELECT * FROM table
WHERE DateStamp > DATE_ADD(NOW(), INTERVAL -1 DAY)

You'll have to make a join:

SELECT A.SalesOrderID, B.Foo
FROM A
JOIN B bo ON bo.id = (
     SELECT TOP 1 id
     FROM B bi
     WHERE bi.SalesOrderID = a.SalesOrderID
     ORDER BY bi.whatever
     )
WHERE A.Date BETWEEN '2000-1-4' AND '2010-1-4'

, assuming that b.id is a PRIMARY KEY on B

In MS SQL 2005 and higher you may use this syntax:

SELECT SalesOrderID, Foo
FROM (
  SELECT A.SalesOrderId, B.Foo,
         ROW_NUMBER() OVER (PARTITION BY B.SalesOrderId ORDER BY B.whatever) AS rn
  FROM A
  JOIN B ON B.SalesOrderID = A.SalesOrderID
  WHERE A.Date BETWEEN '2000-1-4' AND '2010-1-4'
) i
WHERE rn

This will select exactly one record from B for each SalesOrderId.

KEY is normally a synonym for INDEX. The key attribute PRIMARY KEY can also be specified as just KEY when given in a column definition. This was implemented for compatibility with other database systems.

column_definition:
      data_type [NOT NULL | NULL] [DEFAULT default_value]
      [AUTO_INCREMENT] [UNIQUE [KEY] | [PRIMARY] KEY]
      ...

Main difference between JPA and JDBC is level of abstraction.

JDBC is a low level standard for interaction with databases. JPA is higher level standard for the same purpose. JPA allows you to use an object model in your application which can make your life much easier. JDBC allows you to do more things with the Database directly, but it requires more attention. Some tasks can not be solved efficiently using JPA, but may be solved more efficiently with JDBC.

If you are using alphine with docker, do this:

apk --update add gcc make g++ zlib-dev

Message queues are ideal for requests which may take a long time to process. Requests are queued and can be processed offline without blocking the client. If the client needs to be notified of completion, you can provide a way for the client to periodically check the status of the request.

Message queues also allow you to scale better across time. It improves your ability to handle bursts of heavy activity, because the actual processing can be distributed across time.

Note that message queues and web services are orthogonal concepts, i.e. they are not mutually exclusive. E.g. you can have a XML based web service which acts as an interface to a message queue. I think the distinction your looking for is Message Queues versus Request/Response, the latter is when the request is processed synchronously.

Alternatively,

StringBuilder result = new StringBuilder();
for(String string : collection) {
    result.append(string);
    result.append(',');
}
return result.substring(0, result.length() - 1) ;

I had the same issue. I solved it downloading modify-headers firefox add-on and activate it with selenium.

The code in python is the following

fp = webdriver.FirefoxProfile()
path_modify_header = 'C:/xxxxxxx/modify_headers-0.7.1.1-fx.xpi'
fp.add_extension(path_modify_header)

fp.set_preference("modifyheaders.headers.count", 1)
fp.set_preference("modifyheaders.headers.action0", "Add")
fp.set_preference("modifyheaders.headers.name0", "Name_of_header") # Set here the name of the header
fp.set_preference("modifyheaders.headers.value0", "value_of_header") # Set here the value of the header
fp.set_preference("modifyheaders.headers.enabled0", True)
fp.set_preference("modifyheaders.config.active", True)
fp.set_preference("modifyheaders.config.alwaysOn", True)

driver = webdriver.Firefox(firefox_profile=fp)

The cex parameter will do that for you.

a <- c(3, 2, 2, 2, 1, 2 )
barplot(a, beside = T,
        col = 1:6, space = c(0, 2))
legend("topright", 
       legend = c("a", "b", "c", "d", "e", "f"), 
       fill = 1:6, ncol = 2,
       cex = 0.75)

In Angular 6, you can do this:

In your service file:

 function_name(data) {
    const url = `the_URL`;
    let input = new FormData();
    input.append('url', data);   // "url" as the key and "data" as value
    return this.http.post(url, input).pipe(map((resp: any) => resp));
  }

In component.ts file: in any function say xyz,

xyz(){
this.Your_service_alias.function_name(data).subscribe(d => {   // "data" can be your file or image in base64 or other encoding
      console.log(d);
    });
}

According to the release-notes, Java 11 removed the Java EE modules:

java.xml.bind (JAXB) - REMOVED

• Java 8 - OK
• Java 9 - DEPRECATED
• Java 10 - DEPRECATED
• Java 11 - REMOVED

See JEP 320 for more info.

You can fix the issue by using alternate versions of the Java EE technologies. Simply add Maven dependencies that contain the classes you need:

<dependency>
  <groupId>javax.xml.bind</groupId>
  <artifactId>jaxb-api</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-core</artifactId>
  <version>2.3.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.0</version>
</dependency>

Jakarta EE 8 update (Mar 2020)

Instead of using old JAXB modules you can fix the issue by using Jakarta XML Binding from Jakarta EE 8:

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>2.3.3</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>2.3.3</version>
  <scope>runtime</scope>
</dependency>

Jakarta EE 9 update (Nov 2020)

Use latest release of Eclipse Implementation of JAXB 3.0.0:

• Jakarta EE9 API jakarta.xml.bind-api
• compatible implementation jaxb-impl

<dependency>
  <groupId>jakarta.xml.bind</groupId>
  <artifactId>jakarta.xml.bind-api</artifactId>
  <version>3.0.0</version>
</dependency>
<dependency>
  <groupId>com.sun.xml.bind</groupId>
  <artifactId>jaxb-impl</artifactId>
  <version>3.0.0</version>
  <scope>runtime</scope>
</dependency>

Note: Jakarta EE 9 adopts new API package namespace jakarta.xml.bind.*, so update import statements:

javax.xml.bind -> jakarta.xml.bind

With java 8:

Arrays.stream(MyEnum.values()).map(Enum::name)
                    .collect(Collectors.toList()).toArray();

FileReaderJS can read the files for you. You get the file content inside onLoad(e) event handler as e.target.result.

DCEVM supports enhanced class redefinitions and is available for current JDK7 and JDK8.

https://github.com/dcevm/dcevm/releases

HotswapAgent is an free JRebel alternative and supports DCEVM in various Frameworks.

http://hotswapagent.org/

for(map<string, pair<string,string> >::const_iterator it = myMap.begin();
    it != myMap.end(); ++it)
{
    std::cout << it->first << " " << it->second.first << " " << it->second.second << "\n";
}

In C++11, you don't need to spell out map<string, pair<string,string> >::const_iterator. You can use auto

for(auto it = myMap.cbegin(); it != myMap.cend(); ++it)
{
    std::cout << it->first << " " << it->second.first << " " << it->second.second << "\n";
}

Note the use of cbegin() and cend() functions.

Easier still, you can use the range-based for loop:

for(auto elem : myMap)
{
   std::cout << elem.first << " " << elem.second.first << " " << elem.second.second << "\n";
}

ul {
  list-style-type: none;
}

ul > li:before {
  content: "–"; /* en dash */
  position: absolute;
  margin-left: -1.1em; 
}

You can use the following command:

where the '^' means use CTRL key.

From the solutions in this thread, I came up with the following probably overcomplicated solution that lets you delay rendering any html (scripts too) within a using block.

USAGE

Create the "section"

1. Typical scenario: In a partial view, only include the block one time no matter how many times the partial view is repeated in the page:

   @using (Html.Delayed(isOnlyOne: "some unique name for this section")) {
       <script>
           someInlineScript();
       </script>
   }
   

2. In a partial view, include the block for every time the partial is used:

   @using (Html.Delayed()) {
       <b>show me multiple times, @Model.Whatever</b>
   }
   

3. In a partial view, only include the block once no matter how many times the partial is repeated, but later render it specifically by name when-i-call-you:

   @using (Html.Delayed("when-i-call-you", isOnlyOne: "different unique name")) {
       <b>show me once by name</b>
       <span>@Model.First().Value</span>
   }
   

Render the "sections"

(i.e. display the delayed section in a parent view)

@Html.RenderDelayed(); // writes unnamed sections (#1 and #2, excluding #3)
@Html.RenderDelayed("when-i-call-you", false); // writes the specified block, and ignore the `isOnlyOne` setting so we can dump it again
@Html.RenderDelayed("when-i-call-you"); // render the specified block by name
@Html.RenderDelayed("when-i-call-you"); // since it was "popped" in the last call, won't render anything due to `isOnlyOne` provided in `Html.Delayed`

 mediaplayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
 mediaplayer.prepareAsync();
 mediaplayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
      @Override
      public void onPrepared(MediaPlayer mp) {
          mediaplayer.start();
      }
 });

This isn't as easy to do as one might expect -- you can really only do vertical alignment if you know the height of your container. IF this is the case, you can do it with absolute positioning.

The concept is to set the top / left positions at 50%, and then use negative margins (set to half the height / width) to pull the container back to being centered.

Example: http://jsbin.com/ipawe/edit

Basic CSS:

#mydiv { 
    position: absolute;
    top: 50%;
    left: 50%;
    height: 400px;
    width: 700px;
    margin-top: -200px; /* -(1/2 height) */
    margin-left: -350px; /* -(1/2 width) */
  }

One line: $ran[rand(0, count($ran) - 1)]

The best way is to check the type, because undefined/null/false are a tricky thing in JS. So:

if(typeof obj !== "undefined") {
    // obj is a valid variable, do something here.
}

Note that typeof always returns a string, and doesn't generate an error if the variable doesn't exist at all.

Try this:

public  boolean isNumber(String str)
{       
    short count = 0;
    char chc[]  = {'0','1','2','3','4','5','6','7','8','9','.','-','+'};
    for (char c : str.toCharArray())
    {   
        for (int i = 0;i < chc.length;i++)
        {
            if( c  == chc[i]){
                count++;        
            }
         }                      
    }
    if (count != str.length() ) 
        return false;
    else
        return true;
}

@Blender Comment is the best approach. Never hard code the protocol anywhere in the code as it will be difficult to change if you move from http to https. Since you need to manually edit and update all the files.

This is always better as it automatically detect the protocol.

You can also just clone the repo, after cloning is done, just pick the folder or vile that you want. To clone:

git clone https://github.com/somegithubuser/somgithubrepo.git

then go to the cloned DIR and find your file or DIR you want to copy.

This worked for me.

$ echo 54657374696e672031203220330 | xxd -r -p
Testing 1 2 3$

-r tells it to convert hex to ascii as opposed to its normal mode of doing the opposite

-p tells it to use a plain format.

The original question on this post was: How to get Keras and Tensorflow to run with an AMD GPU.

The answer to this question is as followed:

1.) Keras will work if you can make Tensorflow work correctly (optionally within your virtual/conda environment).

2.) To get Tensorflow to work on an AMD GPU, as others have stated, one way this could work is to compile Tensorflow to use OpenCl. To do so read the link below. But for brevity I will summarize the required steps here:

• You will need AMDs proprietary drivers. These are currently only available on Ubuntu 14.04 (the version before Ubuntu decided to change the way the UI is rendered). Support for Ubuntu 16.04 is at the writing of this post limited to a few GPUs through AMDProDrivers. Readers who want to do deep learning on AMD GPUs should be aware of this!

• Compiling Tensorflow with OpenCl support also requires you to obtain and install the following prerequisites: OpenCl headers, ComputeCpp.

• After the prerequisites are fulfilled, configure your build. Note that there are 3 options for compiling Tensorflow: Std Tensorflow (stable), Benoits Steiner's Tensorflow-opencl (developmental), and Luke Iwanski's Tensorflow-opencl (highly experimental) which you can pull from github. Also note that if you decide to build from any of the opencl versions, the question to use opencl will be missing because it is assumed that you are using it. Conversely, this means that if you configure from the standard tensorflow, you will need to select "Yes" when the configure script asks you to use opencl and "NO" for CUDA.

• Then run tests like so:

  $ bazel test --config=sycl -k --test_timeout 1600 -- //tensorflow/... -//tensorflow/contrib/... -//tensorflow/java/... -//tensorflow /compiler/...

Update: Doing this on my setup takes exceedingly long on my setup. The part that takes long are all the tests running. I am not sure what this means but a lot of my tests are timeing out at 1600 seconds. The duration can probably be shortened at the expense of more tests timeing out. Alternatively, you can just build tensor flow without tests. At the time of this writing, running the tests has taken 2 days already.

Or just build the pip package like so:

bazel build --local_resources 2048,.5,1.0 -c opt --config=sycl //tensorflow/tools/pip_package:build_pip_package

Please actually read the blog post over at Codeplay: Lukas Iwansky posted a comprehensive tutorial post on how to get Tensorflow to work with OpenCl just on March 30th 2017. So this is a very recent post. There are also some details which I did not write about here.

As indicated in the many posts above, little bits of information are spread throughout the interwebs. What Lukas' post adds in terms of value is that all the information was put together into one place which should make setting up Tensforflow and OpenCl a bit less daunting. I will only provide a link here:

https://www.codeplay.com/portal/03-30-17-setting-up-tensorflow-with-opencl-using-sycl

A slightly more complete walk-through has been posted here:

http://deep-beta.co.uk/setting-up-tensorflow-with-opencl-using-sycl/

It differs mainly by explicitly telling the user that he/she needs to:

• create symlinks to a subfolder
• and then actually install tensorflow via "python setup.py develop" command.

Note an alternative approach was mentioned above using tensorflow-cl:

https://github.com/hughperkins/tensorflow-cl

I am unable to discern which approach is better at this time though it appears that this approach is less active. Fewer issues are posted, and fewer conversations to resolve those issues are happening. There was a major push last year. Additional pushes have ebbed off since November 2016 although Hugh seems to have pushed some updates a few days ago as of the writing of this post. (Update: If you read some of the documentation readme, this version of tensorflowo now only relies on community support as the main developer is busy with life.)

UPDATE (2017-04-25): I have some notes based on testing tensorflow-opencl below.

• The future user of this package should note that using opencl means that all the heavy-lifting in terms of computing is shifted to the GPU. I mention this because I was personally thinking that the compute work-load would be shared between my CPU and iGPU. This means that the power of your GPU is very important (specifically, bandwidth, and available VRAM).

Following are some numbers for calculating 1 epoch using the CIFAR10 data set for MY SETUP (A10-7850 with iGPU). Your mileage will almost certainly vary!

• Tensorflow (via pip install): ~ 1700 s/epoch
• Tensorflow (w/ SSE + AVX): ~ 1100 s/epoch
• Tensorflow (w/ opencl & iGPU): ~ 5800 s/epoch

You can see that in this particular case performance is worse. I attribute this to the following factors:

• The iGPU only has 1GB. This leads to a lot of copying back and forth between CPU and GPU. (Opencl 1.2 does not have the ability to data pass via pointers yet; instead data has to be copied back and forth.)
• The iGPU only has 512 stream processors (and 32 Gb/s memory bandwidth) which in this case is slower than 4 CPUs using SSE4 + AVX instruction sets.
• The development of tensorflow-opencl is in it's beginning stages, and a lot of optimizations in SYCL etc. have not been done yet.

If you are using an AMD GPU with more VRAM and more stream processors, you are certain to get much better performance numbers. I would be interested to read what numbers people are achieving to know what's possible.

I will continue to maintain this answer if/when updates get pushed.

3.) An alternative way is currently being hinted at which is using AMD's RocM initiative, and miOpen (cuDNN equivalent) library. These are/will be open-source libraries that enable deep learning. The caveat is that RocM support currently only exists for Linux, and that miOpen has not been released to the wild yet, but Raja (AMD GPU head) has said in an AMA that using the above, it should be possible to do deep learning on AMD GPUs. In fact, support is planned for not only Tensorflow, but also Cafe2, Cafe, Torch7 and MxNet.
