The shorthand is:

$(function() {
    // Code here
});

If I understood your question correctly, this should do what you need.

1. you can specifiy the directory you would like to add through $check variable
2. if the directory is already in the list, the output is "dir already listed"
3. if the directory is not yet in the list, it is appended to my_list.txt

In one line: check="/tmp/newdirectory"; [[ -n $(grep "^$check\$" my_list.txt) ]] && echo "dir already listed" || echo "$check" >> my_list.txt

If it were me, I'd probably boil it down to a single selector:

$('someTableSelector tr:not(:first)').remove();

I had also the same problem. Please add this line in application tag in manifest. I hope it will also help you.

android:usesCleartextTraffic="true"

If you want to use the MAX(id) instead of the count, after reading the comments from Pax then the following SQL will give you what you want

SELECT COALESCE(MAX(id)+1, 0) FROM words

If it retures "permission denied" on adb shell -> su...

Go to "Developer Options" -> Root access -> "Apps and ADB"

This will replace all ? with ':

UPDATE dbo.authors    
SET    city = replace(city, '?', '''')
WHERE city LIKE '%?%'

If you need to update more than one column, you can either change city each time you execute to a different column name, or list the columns like so:

UPDATE dbo.authors    
SET    city = replace(city, '?', '''')
      ,columnA = replace(columnA, '?', '''')
WHERE city LIKE '%?%'
OR columnA LIKE '%?%'

I just want to mention a thing, there are many tools can do text processing, e.g. sort, cut, split, join, paste, comm, uniq, column, rev, tac, tr, nl, pr, head, tail.....

they are very handy but you have to learn their options etc.

A lazy way (not the best way) to learn text processing might be: only learn grep , sed and awk. with this three tools, you can solve almost 99% of text processing problems and don't need to memorize above different cmds and options. :)

AND, if you 've learned and used the three, you knew the difference. Actually, the difference here means which tool is good at solving what kind of problem.

a more lazy way might be learning a script language (python, perl or ruby) and do every text processing with it.

This issue seems to be bug in Android Studio.

I tried all other workarounds but the issue was appearing randomly.

I also have custom named apk for output. But Android studio was randomly picking custom apk name and default apk name.

Adding Gradle-aware Make solved the issue.

Following are the steps.

1. Menu Run -> Edit Configuration

2. Select "app" configuration

3. Add Gradle-aware Make to Before Launch actions

You are done.

Following article helped me in finding the solution https://android.jlelse.eu/android-studio-3-1-how-to-fix-it-b49f72eb054f

Setting its background image to none also works:

button {
    background-image: none;
}

Swift has a very clear, specific sequence of operations that are done in initializers. Let's start with some basic examples and work our way up to a general case.

Let's take an object A. We'll define it as follows.

class A {
    var x: Int
    init(x: Int) {
        self.x = x
    }
}

Notice that A does not have a superclass, so it cannot call a super.init() function as it does not exist.

OK, so now let's subclass A with a new class named B.

class B: A {
    var y: Int
    init(x: Int, y: Int) {
        self.y = y
        super.init(x: x)
    }
}

This is a departure from Objective-C where [super init] would typically be called first before anything else. Not so in Swift. You are responsible for ensuring that your instance variables are in a consistent state before you do anything else, including calling methods (which includes your superclass' initializer).

I had the same problem, the logfile showed me this error:

2016/03/30 14:35:51 [error] 11915#0: *3 directory index of "path_scripts/viewerjs/" is forbidden, client: IP.IP.IP.IP,     server: domain.com, request: "GET /scripts/viewerjs/ HTTP/1.1", host: "domain", referrer: "domain.com/new_project/do_update"

I am hosting a PHP app with codeignitor framework. When i wanted to view uploaded files i received a 403 Error.

The problem was, that the nginx.conf was not properly defined. Instead of

index index.html index.htm index.php

i only included

index index.php

I have an index.php in my root and i thought that was enough, i was wrong ;) The hint gave me NginxLibrary

In support to @thorinkor's answer I would extend my answer to use not only @Table (name = "table_name") annotation for entity, but also every child variable of entity class should be annotated with @Column(name = "col_name"). This results into seamless updation to the table on the go.

For those who are looking for a Java class based hibernate config, the rule applies in java based configurations also(NewHibernateUtil). Hope it helps someone else.

OK, the right answer definitely has to do something with the CPU cache. But to use the cache argument can be quite difficult, especially without data.

There are many answers, that led to a lot of discussion, but let's face it: Cache issues can be very complex and are not one dimensional. They depend heavily on the size of the data, so my question was unfair: It turned out to be at a very interesting point in the cache graph.

@Mysticial's answer convinced a lot of people (including me), probably because it was the only one that seemed to rely on facts, but it was only one "data point" of the truth.

That's why I combined his test (using a continuous vs. separate allocation) and @James' Answer's advice.

The graphs below shows, that most of the answers and especially the majority of comments to the question and answers can be considered completely wrong or true depending on the exact scenario and parameters used.

Note that my initial question was at n = 100.000. This point (by accident) exhibits special behavior:

1. It possesses the greatest discrepancy between the one and two loop'ed version (almost a factor of three)

2. It is the only point, where one-loop (namely with continuous allocation) beats the two-loop version. (This made Mysticial's answer possible, at all.)

The result using initialized data:

The result using uninitialized data (this is what Mysticial tested):

And this is a hard-to-explain one: Initialized data, that is allocated once and reused for every following test case of different vector size:

Proposal

Every low-level performance related question on Stack Overflow should be required to provide MFLOPS information for the whole range of cache relevant data sizes! It's a waste of everybody's time to think of answers and especially discuss them with others without this information.

Here is very handy directive angular-datetime. You can use it like this:

<input type="text" datetime="yyyy-MM-dd HH:mm:ss" ng-model="myDate">

It also add mask to your input and perform validation.

Avoid paddings and margins in newsletters, some email clients will ignore this properties.

You can use empty tr and td as was suggested (but this will result in a lot of html), or you can use borders with the same border color as the background of the email. so, instead of padding-top: 40px you can use border-top: 40px solid #ffffff (assuming that the background color of the email is #ffffff)

I've tested this solution in gmail (and gmail for business), yahoo mail, outlook web, outlook desktop, thunderbird, apple mail and more. As far as I can tell, border property is pretty safe to use everywhere.

Example:

<!-- With paddings: WON'T WORK IN ALL EMAIL CLIENTS! -->
<table>

    <tr>

        <td style="padding: 10px 10px 10px 10px">
            <!-- Content goes here -->
        </td>

    </tr>

</table>


<!-- Same result with borders and same border color of the background -->
<table>

    <tr>

        <td style="border: solid 10px #ffffff">
           <!-- Content goes here -->
        </td>

    </tr>

</table>


<!-- Same result using empty td/tr. (A lot more html than borders, get messy on large emails) -->
<table>

    <tr>
        <td colspan="3" height="10" style="height: 10px; line-height: 1px">&nbsp;</td>
    </tr>


    <tr>

        <td width="10" style="width: 10px; line-height: 1px">&nbsp;</td>

        <td><!--Content goes here--></td>

        <td width="10" style="width: 10px; line-height: 1px">&nbsp;</td>

    </tr>


    <tr>
        <td colspan="3" height="10" style="height: 10px; line-height: 1px">&nbsp;</td>
    </tr>

</table>
<!-- With tr/td every property is needed. height must be setted both as attribute and style, same with width, line-height must be setted JIC default value is greater than actual height and without the &nbsp; some email clients won't render the column because is empty. You can remove the colspan and still will work, but is annoying when inspecting the element in browser not to see a perfect square table -->

In addition, here is an excelent guide to make responsive newsletters without mediaqueries. The emails really works everywhere:

In fact, this is a "how to" subject. So, here is the reference implementation:

    public class BOX

        double height, length, breadth;

        public static bool operator == (BOX b1, BOX b2)
        {

                return (object)b2 == null;

            return b1.Equals(b2);
        }

        public static bool operator != (BOX b1, BOX b2)
        {
            return !(b1 == b2);
        }

        public override bool Equals(object obj)
        {
            if (obj == null || GetType() != obj.GetType())
                return false;

            var b2 = (BOX)obj;
            return (length == b2.length && breadth == b2.breadth && height == b2.height);
        }

        public override int GetHashCode()
        {
            return height.GetHashCode() ^ length.GetHashCode() ^ breadth.GetHashCode();
        }
    }

UPDATE: the cast to (object) in the operator == implementation is important, otherwise, it would re-execute the operator == overload, leading to a stackoverflow. Credits to @grek40.

You've already gone down the list of most things that would be helpful, but you could try:

• Exit Android Studio
• Back up your project
• Delete all the .iml files and the .idea folder
• Relaunch Android Studio and reimport your project

By the way, the error messages you see in the Project Structure dialog are bogus for the most part.

UPDATE:

Android Studio 0.4.3 is available in the canary update channel, and should hopefully solve most of these issues. There may be some lingering problems; if you see them in 0.4.3, let us know, and try to give us a reliable set of steps to reproduce so we can ensure we've taken care of all code paths.

Make certain to specify stringsAsFactors=FALSE when creating the dataframe:

> rm(list=ls())
> trigonometry <- data.frame(character(0), numeric(0), stringsAsFactors=FALSE)
> colnames(trigonometry) <- c("theta", "sin.theta")
> trigonometry
[1] theta     sin.theta
<0 rows> (or 0-length row.names)
> trigonometry[nrow(trigonometry) + 1, ] <- c("0", sin(0))
> trigonometry[nrow(trigonometry) + 1, ] <- c("pi/2", sin(pi/2))
> trigonometry
  theta sin.theta
1     0         0
2  pi/2         1
> typeof(trigonometry)
[1] "list"
> class(trigonometry)
[1] "data.frame"

Failing to use stringsAsFactors=FALSE when creating the dataframe will result in the following error when attempting to add the new row:

> trigonometry[nrow(trigonometry) + 1, ] <- c("0", sin(0))
Warning message:
In `[<-.factor`(`*tmp*`, iseq, value = "0") :

You're running the code before the DOM is loaded.

Try this:

Live example:

http://jsfiddle.net/FvMYz/

$(function() {    // Makes sure the code contained doesn't run until
                  //     all the DOM elements have loaded

    $('#colorselector').change(function(){
        $('.colors').hide();
        $('#' + $(this).val()).show();
    });

});

What worked for me was updating Android Studio and updating JAVA_HOME and ANDROID_HOME environment variables. I believe it was caused due to the fact that I updated Java Version (through updater) but did not update jdk.

view.layer.borderWidth = 1.0
view.layer.borderColor = UIColor.lightGray.cgColor

for a monthpicker, using JQuery v 1.7.2, I have the following javascript which is doing just that

$l("[id$=txtDtPicker]").monthpicker({
showOn: "both",
buttonImage: "../../images/Calendar.png",
buttonImageOnly: true,
pattern: 'yyyymm', // Default is 'mm/yyyy' and separator char is not mandatory
monthNames: ['Jan', 'Fev', 'Mar', 'Abr', 'Mai', 'Jun', 'Jul', 'Ago', 'Set', 'Out', 'Nov', 'Dez']
});

This way I was able to call MyService

private REST_API_SERVER = 'http://localhost:4040/abc';
public sendGetRequest() {
   var myFormData = { email: '[email protected]', password: '123' };
   const headers = new HttpHeaders();
   headers.append('Content-Type', 'application/json');
   //HTTP POST REQUEST
   this.httpClient
  .post(this.REST_API_SERVER, myFormData, {
    headers: headers,
   })
  .subscribe((data) => {
    console.log("i'm from service............", data, myFormData, headers);
    return data;
  });
}

We're coding after MISRA standard. The ruleset has "MUST" and "CAN" parts, and we spent hours of discussing which rules we don't want to apply and why, when someday upper management said "We want to tell our customers we're 100% compliant. Tomorrow, we apply all."

Among the rules is one that says: No bit operations on signed data. Trying to find out what the rule is for, the explanation was presented: There is no guarantee about the bit representation of signed data. There is only 2s complement in the world, but the standard makes no guarantee!

Anyway, doesn't sound like a big thing - who wants to declare bitcoded variables as signed?

However, the holy rules checker interprets "integer promotion" as "promotion to signed" and the C standards guru says it has to be. And every bit operation does integer promotion. So instead of:

a &= ~(1 << i)

you have to write:

a = (unsigned int)(a & (unsigned int)~(unsigned int)(1 << i))

which is obviously much more readable and portable and all. Fortunately I found out that a shifted 1u stays unsigned. So you can reduce it to:

a = (unsigned int)(a & (unsigned int)~(1u << i))

Funnily, there is a rule that was not activated: Forbid using funny characters like '\' in #include. The DOS-corrupted folks won't believe that writing #include "bla/foo.h" does work even with every windows compiler and is much more portable.

Nvm can be used to manage various node version :

• Step1: Download nvm for Windows

• Step2: Choose nvm-setup.zip

• Step3: Unzip & click on installer.

• Step4: Check if nvm properly installed, In new command prompt type nvm

• Step5: Install node js using nvm : nvm install <version> : The version can be a node.js version or "latest" for the latest stable version

• Step6: check node version - node -v

• Step7(Optional)If you want to install another version of node js - Use STEP 5 with different version.

• Step8: Check list node js version - nvm list

• Step9: If you want to use specific node version do - nvm use <version>

I am doing something like below:

    StringBuilder stringBuilder = new StringBuilder();
    for (int i = 0; i < value.length; i++) {
        stringBuilder.append(values[i]);
        if (value.length-1) {
            stringBuilder.append(", ");
        }
    }

One missing difference is: std::unique_lock can be moved but std::lock_guard can't be moved.

Note: Both cant be copied.

Here is some code from above added with actual action code (point 1 and 2);

func tableView(_ tableView: UITableView, trailingSwipeActionsConfigurationForRowAt indexPath: IndexPath) -> UISwipeActionsConfiguration? {
    let deleteAction = UIContextualAction(style: .destructive, title: "Delete") { _, _, completionHandler in

        // 1. remove object from your array
        scannedItems.remove(at: indexPath.row)
        // 2. reload the table, otherwise you get an index out of bounds crash
        self.tableView.reloadData()

        completionHandler(true)
    }
    deleteAction.backgroundColor = .systemOrange
    let configuration = UISwipeActionsConfiguration(actions: [deleteAction])
    configuration.performsFirstActionWithFullSwipe = true
    return configuration
}

If you want to do it on your local machine instead of in the context of SQL server then I would use the following. It is what we use at my company.

$ServerName = "_ServerName_"
$DatabaseName = "_DatabaseName_"
$Query = "SELECT * FROM Table WHERE Column = ''"

#Timeout parameters
$QueryTimeout = 120
$ConnectionTimeout = 30

#Action of connecting to the Database and executing the query and returning results if there were any.
$conn=New-Object System.Data.SqlClient.SQLConnection
$ConnectionString = "Server={0};Database={1};Integrated Security=True;Connect Timeout={2}" -f $ServerName,$DatabaseName,$ConnectionTimeout
$conn.ConnectionString=$ConnectionString
$conn.Open()
$cmd=New-Object system.Data.SqlClient.SqlCommand($Query,$conn)
$cmd.CommandTimeout=$QueryTimeout
$ds=New-Object system.Data.DataSet
$da=New-Object system.Data.SqlClient.SqlDataAdapter($cmd)
[void]$da.fill($ds)
$conn.Close()
$ds.Tables

Just fill in the $ServerName, $DatabaseName and the $Query variables and you should be good to go.

I am not sure how we originally found this out, but there is something very similar here.

OpenCV Specific

Opencv supports filesystem, probably through its dependency Boost.

Here is a simple demo to create customview (compoundview) by inflating from xml

attrs.xml

<resources>

    <declare-styleable name="CustomView">
        <attr format="string" name="text"/>
        <attr format="reference" name="image"/>
    </declare-styleable>
</resources>

CustomView.kt

class CustomView @JvmOverloads constructor(context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0) :
        ConstraintLayout(context, attrs, defStyleAttr) {

    init {
        init(attrs)
    }

    private fun init(attrs: AttributeSet?) {
        View.inflate(context, R.layout.custom_layout, this)

        val ta = context.obtainStyledAttributes(attrs, R.styleable.CustomView)
        try {
            val text = ta.getString(R.styleable.CustomView_text)
            val drawableId = ta.getResourceId(R.styleable.CustomView_image, 0)
            if (drawableId != 0) {
                val drawable = AppCompatResources.getDrawable(context, drawableId)
                image_thumb.setImageDrawable(drawable)
            }
            text_title.text = text
        } finally {
            ta.recycle()
        }
    }
}

custom_layout.xml

We should use merge here instead of ConstraintLayout because

If we use ConstraintLayout here, layout hierarchy will be ConstraintLayout->ConstraintLayout -> ImageView + TextView => we have 1 redundant ConstraintLayout => not very good for performance

<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    tools:parentTag="android.support.constraint.ConstraintLayout">

    <ImageView
        android:id="@+id/image_thumb"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        tools:ignore="ContentDescription"
        tools:src="@mipmap/ic_launcher" />

    <TextView
        android:id="@+id/text_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintEnd_toEndOf="@id/image_thumb"
        app:layout_constraintStart_toStartOf="@id/image_thumb"
        app:layout_constraintTop_toBottomOf="@id/image_thumb"
        tools:text="Text" />

</merge>

Using activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"

You can create custom material rating bar by defining drawable xml using material icon of your choice and then applying custom drawable to rating bar using progressDrawable attribute.

For infomration about customizing rating bar see http://www.zoftino.com/android-ratingbar-and-custom-ratingbar-example

Below drawable xml uses thumbs up icon for rating bar.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@android:id/background">
        <bitmap
            android:src="@drawable/thumb_up"
            android:tint="?attr/colorControlNormal" />
    </item>
    <item android:id="@android:id/secondaryProgress">
        <bitmap
            android:src="@drawable/thumb_up"
            android:tint="?attr/colorControlActivated" />
    </item>
    <item android:id="@android:id/progress">

The curly braces mean concatenation, from most significant bit (MSB) on the left down to the least significant bit (LSB) on the right. You are creating a 32-bit bus (result) whose 16 most significant bits consist of 16 copies of bit 15 (the MSB) of the a bus, and whose 16 least significant bits consist of just the a bus (this particular construction is known as sign extension, which is needed e.g. to right-shift a negative number in two's complement form and keep it negative rather than introduce zeros into the MSBits).

There is a tutorial here*, but it doesn't explain too much more than the above paragraph.

For what it's worth, the nested curly braces around a[15:0] are superfluous.

*Beware: the example within the tutorial link contains a typo when demonstrating multiple concatenations - the (2{C}} should be a {2{2}}.

For a String constant you have no choice other than escaping via backslash.

Maybe you find the MyBatis project interesting. It is a thin layer over JDBC where you can externalize your SQL queries in XML configuration files without the need to escape double quotes.

Conditionizr (see docs) will add browser CSS classes to your html element, including ie10.

It appears that your HTML syntax is incorrect for the table cell. Before you try the other idea below, confirm if this works or not... You can also try adding this to your table itself: table-layout:fixed.. .

<td style="overflow: hidden; width: 280px; text-align: left; valign: top; whitespace: nowrap;">
   [content]
</td>

New HTML

<td>
   <div class="MyClass"">
       [content]
   </div>
</td>

CSS Class:

.MyClass{
   height: 280px; 
   width: 456px; 
   overflow: hidden;
   white-space: nowrap;
}

On a linux server you can just use this commands to reconfigure Tomcat to listen on port 80:

sed -i 's|port="8080"|port="80"|g' /etc/tomcat?/server.xml
sed -i 's|#AUTHBIND=no|AUTHBIND=yes|g' /etc/default/tomcat?
service tomcat8 restart

You can write your own equals function:

• dicts are equal if: 1) all keys are equal, 2) all values are equal
• lists are equal if: all items are equal and in the same order
• primitives are equal if a == b

Because you're dealing with json, you'll have standard python types: dict, list, etc., so you can do hard type checking if type(obj) == 'dict':, etc.

Rough example (not tested):

def json_equals(jsonA, jsonB):
    if type(jsonA) != type(jsonB):
        # not equal
        return False
    if type(jsonA) == dict:
        if len(jsonA) != len(jsonB):
            return False
        for keyA in jsonA:
            if keyA not in jsonB or not json_equal(jsonA[keyA], jsonB[keyA]):
                return False
    elif type(jsonA) == list:
        if len(jsonA) != len(jsonB):
            return False
        for itemA, itemB in zip(jsonA, jsonB):
            if not json_equal(itemA, itemB):
                return False
    else:
        return jsonA == jsonB

Just tried this solution, we don't have to even write int.

int[][] twoDim = { { 1, 2 }, { 3, 7 }, { 8, 9 }, { 4, 2 }, { 5, 3 } };
Arrays.sort(twoDim, (a1,a2) -> a2[0] - a1[0]);

This thing will also work, it automatically detects the type of string.

What are you loading the files for - configuration or data (like an input file) or as a resource?

• If as a resource, follow the suggestion and example given by Will and Justin
• If configuration, then you can use a ResourceBundle or Spring (if your configuration is more complex).
• If you need to read a file in order to process the data inside, this code snippet may help BufferedReader file = new BufferedReader(new FileReader(filename)) and then read each line of the file using file.readLine(); Don't forget to close the file.

There is a folder called "Properties" under your project root folder, and there are *.settings file under that folder. That's where it gets stored.

Simply try:

echo apache_request_headers()[3];

You can write to files with streams.

Just do it like this:

const fs = require('fs');

const stream = fs.createWriteStream('./test.txt');
stream.write("Example text");

This is a quirk of the C grammar. A label (Cleanup:) is not allowed to appear immediately before a declaration (such as char *str ...;), only before a statement (printf(...);). In C89 this was no great difficulty because declarations could only appear at the very beginning of a block, so you could always move the label down a bit and avoid the issue. In C99 you can mix declarations and code, but you still can't put a label immediately before a declaration.

You can put a semicolon immediately after the label's colon (as suggested by Renan) to make there be an empty statement there; this is what I would do in machine-generated code. Alternatively, hoist the declaration to the top of the function:

int main (void) 
{
    char *str;
    printf("Hello ");
    goto Cleanup;
Cleanup:
    str = "World\n";
    printf("%s\n", str);
    return 0;
}

Very easy:

Here is what you want:

import os.path as path

two_up =  path.abspath(path.join(__file__ ,"../.."))

div.abc.xyz {
    /* rules go here */
}

... or simply:

.abc.xyz {
    /* rules go here */
}

you could use ⊕ or ⊗

You could do

matcher = re.compile('MICHAEL89', re.IGNORECASE)
filter(matcher.match, USERNAMES) 

Update: played around a bit and am thinking you could get a better short-circuit type approach using

matcher = re.compile('MICHAEL89', re.IGNORECASE)
if any( ifilter( matcher.match, USERNAMES ) ):
    #your code here

The ifilter function is from itertools, one of my favorite modules within Python. It's faster than a generator but only creates the next item of the list when called upon.

You can sort a map by value as below, more example here

//Sort a Map by their Value.
Map<Integer, String> random = new HashMap<Integer, String>();

random.put(1,"z");
random.put(6,"k");
random.put(5,"a");
random.put(3,"f");
random.put(9,"c");

Map<Integer, String> sortedMap =
        random.entrySet().stream()
                .sorted(Map.Entry.comparingByValue())
                .collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue,
                        (e1, e2) -> e2, LinkedHashMap::new));
System.out.println("Sorted Map: " + Arrays.toString(sortedMap.entrySet().toArray()));

remap is an option that makes mappings work recursively. By default it is on and I'd recommend you leave it that way. The rest are mapping commands, described below:

:map and :noremap are recursive and non-recursive versions of the various mapping commands. For example, if we run:

:map j gg           (moves cursor to first line)
:map Q j            (moves cursor to first line)
:noremap W j        (moves cursor down one line)

Then:

• j will be mapped to gg.
• Q will also be mapped to gg, because j will be expanded for the recursive mapping.
• W will be mapped to j (and not to gg) because j will not be expanded for the non-recursive mapping.

Now remember that Vim is a modal editor. It has a normal mode, visual mode and other modes.

For each of these sets of mappings, there is a mapping that works in normal, visual, select and operator modes (:map and :noremap), one that works in normal mode (:nmap and :nnoremap), one in visual mode (:vmap and :vnoremap) and so on.

For more guidance on this, see:

:help :map
:help :noremap
:help recursive_mapping
:help :map-modes

The only case where you may want such a function is an UPDATE query which will alter your table to store Firstname and Lastname into separate fields.

Database design must follow certain rules, and Database Normalization is among most important ones

Step 1: use https://modernizr.com/

Step 2: use the html class .regions to select only Safari

a { color: blue; }
html.regions a { color: green; }

Modernizr will add html classes to the DOM based on what the current browser supports. Safari supports regions http://caniuse.com/#feat=css-regions whereas other browsers do not (yet anyway). This method is also very effective in selecting different versions of IE. May the force be with you.

You can set enable/disable bounce or scrolling the tableview by selecting/deselecting these in the Scroll View area

Put this on an event

$(function(){
    $('.package').click(function(){
       var content = $('.container').html();
       $(this).html(content);
    });
});

You can use this method for any minute / hour / period (aka am/pm) combination:

- (NSDate *)todayModifiedWithHours:(NSString *)hours
                           minutes:(NSString *)minutes
                         andPeriod:(NSString *)period
{
    NSDate *todayModified = NSDate.date;

    NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar];

    NSDateComponents *components = [calendar components:NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit|NSMinuteCalendarUnit fromDate:todayModified];

    [components setMinute:minutes.intValue];

    int hour = 0;

    if ([period.uppercaseString isEqualToString:@"AM"]) {

        if (hours.intValue == 12) {
            hour = 0;
        }
        else {
            hour = hours.intValue;
        }
    }
    else if ([period.uppercaseString isEqualToString:@"PM"]) {

        if (hours.intValue != 12) {
            hour = hours.intValue + 12;
        }
        else {
            hour = 12;
        }
    }
    [components setHour:hour];

    todayModified = [calendar dateFromComponents:components];

    return todayModified;
}

Requested Example:

NSDate *todayAt10AM = [self todayModifiedWithHours:@"10"
                                           minutes:@"00"
                                         andPeriod:@"am"];

Your code could look more like:

<?php
session_start();
$errorMsg = "";
$validUser = $_SESSION["login"] === true;
if(isset($_POST["sub"])) {
  $validUser = $_POST["username"] == "admin" && $_POST["password"] == "password";
  if(!$validUser) $errorMsg = "Invalid username or password.";
  else $_SESSION["login"] = true;
}
if($validUser) {
   header("Location: /login-success.php"); die();
}
?>
<!DOCTYPE html>
<html>
<head>
  <meta http-equiv="content-type" content="text/html;charset=utf-8" />
  <title>Login</title>
</head>
<body>
  <form name="input" action="" method="post">
    <label for="username">Username:</label><input type="text" value="<?= $_POST["username"] ?>" id="username" name="username" />
    <label for="password">Password:</label><input type="password" value="" id="password" name="password" />
    <div class="error"><?= $errorMsg ?></div>
    <input type="submit" value="Home" name="sub" />
  </form>
</body>
</html>

Now, when the page is redirected based on the header('LOCATION:wherever.php), put session_start() at the top of the page and test to make sure $_SESSION['login'] === true. Remember that == would be true if $_SESSION['login'] == 1 as well. Of course, this is a bad idea for security reasons, but my example may teach you a different way of using PHP.

Default file format is Parquet with spark.read.. and file reading csv that why you are getting the exception. Specify csv format with api you are trying to use

You can do it like this:

class UsersController < ApplicationController
  ## Exception Handling
  class NotActivated < StandardError
  end

  rescue_from NotActivated, :with => :not_activated

  def not_activated(exception)
    flash[:notice] = "This user is not activated."
    Event.new_event "Exception: #{exception.message}", current_user, request.remote_ip
    redirect_to "/"
  end

  def show
      // Do something that fails..
      raise NotActivated unless @user.is_activated?
  end
end

What you're doing here is creating a class "NotActivated" that will serve as Exception. Using raise, you can throw "NotActivated" as an Exception. rescue_from is the way of catching an Exception with a specified method (not_activated in this case). Quite a long example, but it should show you how it works.

Instead of using XML to add margin between items in RecyclerView, it's better way to use RecyclerView.ItemDecoration that provide by android framework.

So, I create a library to solve this issue.

https://github.com/TheKhaeng/recycler-view-margin-decoration

Add an onChange handler to each of your TextField and DropDownMenu elements. When it is called, save the new value of these inputs in the state of your Content component. In render, retrieve these values from state and pass them as the value prop. See Controlled Components.

var Content = React.createClass({

    getInitialState: function() {
        return {
            textFieldValue: ''
        };
    },

    _handleTextFieldChange: function(e) {
        this.setState({
            textFieldValue: e.target.value
        });
    },

    render: function() {
        return (
            <div>
                <TextField value={this.state.textFieldValue} onChange={this._handleTextFieldChange} />
            </div>
        )
    }

});

Now all you have to do in your _handleClick method is retrieve the values of all your inputs from this.state and send them to the server.

You can also use the React.addons.LinkedStateMixin to make this process easier. See Two-Way Binding Helpers. The previous code becomes:

var Content = React.createClass({

    mixins: [React.addons.LinkedStateMixin],

    getInitialState: function() {
        return {
            textFieldValue: ''
        };
    },

    render: function() {
        return (
            <div>
                <TextField valueLink={this.linkState('textFieldValue')} />
            </div>
        )
    }

});

Pull right was depreciated as of v3.1.0 . Just a heads up.

http://getbootstrap.com/components/#callout-dropdown-pull-right

You can use LIKE instead of =. Without any wildcards this will have the same effect.

DECLARE @Village TABLE
        (CastleType TEXT)

INSERT INTO @Village
VALUES
  (
    'foo'
  )

SELECT *
FROM   @Village
WHERE  [CastleType] LIKE 'foo' 

text is deprecated. Changing to varchar(max) will be easier to work with.

Also how large is the data likely to be? If you are going to be doing equality comparisons you will ideally want to index this column. This isn't possible if you declare the column as anything wider than 900 bytes though you can add a computed checksum or hash column that can be used to speed this type of query up.

A nice simple solution for parsing a JSON Response to HTML.

var json_response = jQuery.parseJSON(data);
html_response += 'JSON Response:<br />';

jQuery.each(json_response, function(k, v) {
    html_response += outputJSONReponse(k, v);
});

function outputJSONReponse(k, v) {
    var html_response = k + ': ';

    if(jQuery.isArray(v) || jQuery.isPlainObject(v)) {
        jQuery.each(v, function(j, w) {
            html_response += outputJSONReponse(j, w);
        });
    } else {
        html_response += v + '<br />';
    }

    return html_response;
}

 DateTime.Today.ToString("MM/dd/yy")

Look at the docs for custom date and time format strings for more info.

(Oh, and I hope this app isn't destined for other cultures. That format could really confuse a lot of people... I've never understood the whole month/day/year thing, to be honest. It just seems weird to go "middle/low/high" in terms of scale like that.)

For development you can disable password policy if no other profile was set (i.e. disable password expiration in default one):

ALTER PROFILE "DEFAULT" LIMIT PASSWORD_VERIFY_FUNCTION NULL;

Then, reset password and unlock user account. It should never expire again:

alter user user_name identified by new_password account unlock;

There can be one more approach. However it is not as efficient as the one already suggested in answers.

• Create a path vector for the node n1.

• Create a second path vector for the node n2.

• Path vector implying the set nodes from that one would traverse to reach the node in question.

• Compare both path vectors. The index where they mismatch, return the node at that index - 1. This would give the LCA.

Cons for this approach:

Need to traverse the tree twice for calculating the path vectors. Need addtional O(h) space to store path vectors.

However this is easy to implement and understand as well.

Code for calculating the path vector:

private boolean findPathVector (TreeNode treeNode, int key, int pathVector[], int index) {

        if (treeNode == null) {
            return false;
        }

        pathVector [index++] = treeNode.getKey ();

        if (treeNode.getKey () == key) {
            return true;
        }
        if (findPathVector (treeNode.getLeftChild (), key, pathVector, index) || 
            findPathVector (treeNode.getRightChild(), key, pathVector, index)) {

            return true;        
        }

        pathVector [--index] = 0;
        return false;       
    }

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

I had the same issue. I started to reset the default of the column.

change_column :users, :column_name, :boolean, default: nil
change_column :users, :column_name, :integer, using: 'column_name::integer', default: 0, null: false

Base URL in JavaScript

You can access the current url quite easily in JavaScript with window.location

You have access to the segments of that URL via this locations object. For example:

// This article:
// https://stackoverflow.com/questions/21246818/how-to-get-the-base-url-in-javascript

var base_url = window.location.origin;
// "http://stackoverflow.com"

var host = window.location.host;
// stackoverflow.com

var pathArray = window.location.pathname.split( '/' );
// ["", "questions", "21246818", "how-to-get-the-base-url-in-javascript"]

In Chrome Dev Tools, you can simply enter window.location in your console and it will return all of the available properties.

Further reading is available on this Stack Overflow thread

Assuming your "states" collection is like:

{"name" : "Spain", "cities" : [ { "name" : "Madrid" }, { "name" : null } ] }
{"name" : "France" }

The query to find states with null cities would be:

db.states.find({"cities.name" : {"$eq" : null, "$exists" : true}});

It is a common mistake to query for nulls as:

db.states.find({"cities.name" : null});

because this query will return all documents lacking the key (in our example it will return Spain and France). So, unless you are sure the key is always present you must check that the key exists as in the first query.

Use ng-disabled or a special CSS class with ng-class

<input data-ng-model="userInf.username"  
       class="span12 editEmail" 
       type="text"  
       placeholder="[email protected]"  
       pattern="[^@]+@[^@]+\.[a-zA-Z]{2,6}" 
       required 
       ng-disabled="{expression or condition}"
/>

Following @user2019515 answer, I needed to handle exclusions to my archive. here is the resulting function with an example.

Zip Function :

function Zip($source, $destination, $include_dir = false, $exclusions = false){
    // Remove existing archive
    if (file_exists($destination)) {
        unlink ($destination);
    }

    $zip = new ZipArchive();
    if (!$zip->open($destination, ZIPARCHIVE::CREATE)) {
        return false;
    }
    $source = str_replace('\\', '/', realpath($source));
    if (is_dir($source) === true){
        $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($source), RecursiveIteratorIterator::SELF_FIRST);
        if ($include_dir) {
            $arr = explode("/",$source);
            $maindir = $arr[count($arr)- 1];
            $source = "";
            for ($i=0; $i < count($arr) - 1; $i++) {
                $source .= '/' . $arr[$i];
            }
            $source = substr($source, 1);
            $zip->addEmptyDir($maindir);
        }
        foreach ($files as $file){
            // Ignore "." and ".." folders
            $file = str_replace('\\', '/', $file);
            if(in_array(substr($file, strrpos($file, '/')+1), array('.', '..'))){
                continue;
            }

            // Add Exclusion
            if(($exclusions)&&(is_array($exclusions))){
                if(in_array(str_replace($source.'/', '', $file), $exclusions)){
                    continue;
                }
            }

            $file = realpath($file);
            if (is_dir($file) === true){
                $zip->addEmptyDir(str_replace($source . '/', '', $file . '/'));
            } elseif (is_file($file) === true){
                $zip->addFromString(str_replace($source . '/', '', $file), file_get_contents($file));
            }
        }
    } elseif (is_file($source) === true){
        $zip->addFromString(basename($source), file_get_contents($source));
    }
    return $zip->close();
}

How to use it :

function backup(){
    $backup = 'tmp/backup-'.$this->site['version'].'.zip';
    $exclusions = [];
    // Excluding an entire directory
    $files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator('tmp/'), RecursiveIteratorIterator::SELF_FIRST);
    foreach ($files as $file){
        array_push($exclusions,$file);
    }
    // Excluding a file
    array_push($exclusions,'config/config.php');
    // Excluding the backup file
    array_push($exclusions,$backup);
    $this->Zip('.',$backup, false, $exclusions);
}

If you don't want any dependency on Spring's HATEOAS or javax.* namespace, use ServletUriComponentsBuilder to get URI of current request:

import org.springframework.web.util.UriComponentsBuilder;

ServletUriComponentsBuilder.fromCurrentRequest();
ServletUriComponentsBuilder.fromCurrentRequestUri();

Save your username, password and sever name in an RDP file and run the RDP file from your script

Essentially the same as Gringo Suave's answer, but with a generator:

from datetime import datetime, timedelta


def datetime_range(start=None, end=None):
    span = end - start
    for i in xrange(span.days + 1):
        yield start + timedelta(days=i)

Then you can use it as follows:

In: list(datetime_range(start=datetime(2014, 1, 1), end=datetime(2014, 1, 5)))
Out: 
[datetime.datetime(2014, 1, 1, 0, 0),
 datetime.datetime(2014, 1, 2, 0, 0),
 datetime.datetime(2014, 1, 3, 0, 0),
 datetime.datetime(2014, 1, 4, 0, 0),
 datetime.datetime(2014, 1, 5, 0, 0)]

Or like this:

In []: for date in datetime_range(start=datetime(2014, 1, 1), end=datetime(2014, 1, 5)):
   ...:     print date
   ...:     
2014-01-01 00:00:00
2014-01-02 00:00:00
2014-01-03 00:00:00
2014-01-04 00:00:00
2014-01-05 00:00:00

Use the -o option.

git commit -o path/to/myfile -m "the message"

-o, --only commit only specified files

The setReadOnly(state) is very useful for forms, we can set any field to setReadOnly(state) directly or from various condition.But I prefer to use readOnly for setting opacity to the selector otherwise the attr='disabled' also worked like the same way.

readOnly examples:

$('input').setReadOnly(true);

or through the various codition like

var same = this.checked;
$('input').setReadOnly(same);

here we are using the state boolean value to set and remove readonly attribute from the input depending on a checkbox click.

There is an easy method to wrap your data and send it to server as if you were sending an HTML form using POST. you can do that using FormData object as following:

data = new FormData()
data.set('Foo',1)
data.set('Bar','boo')

let request = new XMLHttpRequest();
request.open("POST", 'some_url/', true);
request.send(data)

now you can handle the data on the server-side just like the way you deal with reugular HTML Forms.

Additional Info

It is advised that you must not set Content-Type header when sending FormData since the browser will take care of that.

In an ideal case, you would like to test for all three values, null, "" or empty(field doesn't exist in the record)

You can do the following.

db.users.find({$and: [{"name" : {$nin: ["", null]}}, {"name" : {$exists: true}}]})

I encounter a problem in quasar which is a mobile framework based vue, the tidle syntax ~assets/cover.jpg works in normal component, but not in my dynamic defined component, that is defined by

let c=Vue.component('compName',{...})

finally this work:

    computed: {
      coverUri() {
        return require('../assets/cover.jpg');
      }
    }

<q-img class="coverImg" :src="coverUri" :height="uiBook.coverHeight" spinner-color="white"/>

according to the explain at https://quasar.dev/quasar-cli/handling-assets

In *.vue components, all your templates and CSS are parsed by vue-html-loader and css-loader to look for asset URLs. For example, in <img src="./logo.png"> and background: url(./logo.png), "./logo.png" is a relative asset path and will be resolved by Webpack as a module dependency.

Using jQuery:

   $('#test').hide();

Using Javascript:

document.getElementById("test").style.display="none";

Threw an error "Cannot set property 'display' of undefined"

So, fix for this would be:

document.getElementById("test").style="display:none";

where your html code will look like this:

<div style="display:inline-block" id="test"></div>

This returns the last modified date and its age.

DateTime.Now.Subtract(System.IO.File.GetLastWriteTime(FilePathwithName).Date)

If you want a generic solution without boxing:

public class KeyBasedEqualityComparer<T, TKey> : IEqualityComparer<T>
{
    private readonly Func<T, TKey> _keyGetter;

    public KeyBasedEqualityComparer(Func<T, TKey> keyGetter)
    {
        _keyGetter = keyGetter;
    }

    public bool Equals(T x, T y)
    {
        return EqualityComparer<TKey>.Default.Equals(_keyGetter(x), _keyGetter(y));
    }

    public int GetHashCode(T obj)
    {
        TKey key = _keyGetter(obj);

        return key == null ? 0 : key.GetHashCode();
    }
}

public static class KeyBasedEqualityComparer<T>
{
    public static KeyBasedEqualityComparer<T, TKey> Create<TKey>(Func<T, TKey> keyGetter)
    {
        return new KeyBasedEqualityComparer<T, TKey>(keyGetter);
    }
}

usage:

KeyBasedEqualityComparer<Class_reglement>.Create(x => x.Numf)

Overriding navigationBar(_ navigationBar:shouldPop): This is not a good idea, even if it works. for me it generated random crashes on navigating back. I advise you to just override the back button by removing the default backButton from navigationItem and creating a custom back button like below:

override func viewDidLoad(){
   super.viewDidLoad()
   
   navigationItem.leftBarButton = .init(title: "Go Back", ... , action: #selector(myCutsomBackAction) 

   ...
 
}

========================================

Building on previous responses with UIAlert in Swift5 in a Asynchronous way

protocol NavigationControllerBackButtonDelegate {
    func shouldPopOnBackButtonPress(_ completion: @escaping (Bool) -> ())
}

extension UINavigationController: UINavigationBarDelegate {
    public func navigationBar(_ navigationBar: UINavigationBar, shouldPop item: UINavigationItem) -> Bool {
      
        if viewControllers.count < navigationBar.items!.count {
            return true
        }
        
        // Check if we have a view controller that wants to respond to being popped
        
        if let viewController = topViewController as? NavigationControllerBackButtonDelegate {
            
            viewController.shouldPopOnBackButtonPress { shouldPop in
                if (shouldPop) {
                    /// on confirm => pop
                    DispatchQueue.main.async {
                        self.popViewController(animated: true)
                    }
                } else {
                    /// on cancel => do nothing
                }
            }
            /// return false => so navigator will cancel the popBack
            /// until user confirm or cancel
            return false
        }else{
            DispatchQueue.main.async {
                self.popViewController(animated: true)
            }
        }
        return true
    }
}

On your controller

extension MyController: NavigationControllerBackButtonDelegate {
    
    func shouldPopOnBackButtonPress(_ completion: @escaping (Bool) -> ()) {
    
        let msg = "message"
        
        /// show UIAlert
        alertAttention(msg: msg, actions: [
            
            .init(title: "Continuer", style: .destructive, handler: { _ in
                completion(true)
            }),
            .init(title: "Annuler", style: .cancel, handler: { _ in
                completion(false)
            })
            ])
   
    }

}

The simplest way is with the pkill command. In your case:

pkill -9 -t pts/6
pkill -9 -t pts/9
pkill -9 -t pts/10

Regarding tty sessions, the commands below are always useful:

w - shows active terminal sessions

tty - shows your current terminal session (so you won't close it by accident)

last | grep logged - shows currently logged users

Sometimes we want to close all sessions of an idle user (ie. when connections are lost abruptly).

pkill -u username - kills all sessions of 'username' user.

And sometimes when we want to kill all our own sessions except the current one, so I made a script for it. There are some cosmetics and some interactivity (to avoid accidental running on the script).

#!/bin/bash
MYUSER=`whoami`
MYSESSION=`tty | cut -d"/" -f3-`
OTHERSESSIONS=`w $MYUSER | grep "^$MYUSER" | grep -v "$MYSESSION" | cut -d" " -f2`
printf "\e[33mCurrent session\e[0m: $MYUSER[$MYSESSION]\n"

if [[ ! -z $OTHERSESSIONS ]]; then
  printf "\e[33mOther sessions:\e[0m\n"
  w $MYUSER | egrep "LOGIN@|^$MYUSER" | grep -v "$MYSESSION" | column -t
  echo ----------
  read -p "Do you want to force close all your other sessions? [Y]Yes/[N]No: " answer
  answer=`echo $answer | tr A-Z a-z`
  confirm=("y" "yes")

  if [[ "${confirm[@]}" =~ "$answer" ]]; then
  for SESSION in $OTHERSESSIONS
    do
         pkill -9 -t $SESSION
         echo Session $SESSION closed.
    done
  fi
else
        echo "There are no other sessions for the user '$MYUSER'".
fi

If it is a simple py script refer here

Else for GUI :

$ pip3 install cx_Freeze

1) Create a setup.py file and put in the same directory as of the .py file you want to convert.

2)Copy paste the following lines in the setup.py and do change the "filename.py" into the filename you specified.

from cx_Freeze import setup, Executable
setup(
    name="GUI PROGRAM",
    version="0.1",
    description="MyEXE",
    executables=[Executable("filename.py", base="Win32GUI")],
    )

3) Run the setup.py "$python setup.py build"

4)A new directory will be there there called "build". Inside it you will get your .exe file to be ready to launced directly. (Make sure you copy paste the images files and other external files into the build directory)

The most canonical approach when wanting to delete files over a certain duration is by using the file's LastWriteTime (Last time the file was modified):

Directory.GetFiles(dirName)
         .Select(f => new FileInfo(f))
         .Where(f => f.LastWriteTime < DateTime.Now.AddMonths(-3))
         .ToList()
         .ForEach(f => f.Delete());

(The above based on Uri's answer but with LastWriteTime.)

Whenever you hear people talking about deleting files older than a certain time frame (which is a pretty common activity), doing it based on the file's LastModifiedTime is almost always what they are looking for.

Alternatively, for very unusual circumstances you could use the below, but use these with caution as they come with caveats.

CreationTime
.Where(f => f.CreationTime < DateTime.Now.AddMonths(-3))

The time the file was created in the current location. However, be careful if the file was copied, it will be the time it was copied and CreationTime will be newer than the file's LastWriteTime.

LastAccessTime
.Where(f => f.LastAccessTime < DateTime.Now.AddMonths(-3))

If you want to delete the files based on the last time they were read you could use this but, there is no guarantee it will be updated as it can be disabled in NTFS. Check fsutil behavior query DisableLastAccess to see if it is on. Also under NTFS it may take up to an hour for the file's LastAccessTime to update after it was accessed.

I did it like this and it works just fine (version 5.5.41):

# prepare column list using info from a table of choice
SET @dyn_colums = (SELECT REPLACE(
GROUP_CONCAT(`COLUMN_NAME`), ',column_name_to_remove','') 
FROM `INFORMATION_SCHEMA`.`COLUMNS` WHERE 
`TABLE_SCHEMA`='database_name' AND `TABLE_NAME`='table_name');

# set sql command using prepared columns
SET @sql = CONCAT("SELECT ", @dyn_colums, " FROM table_name");

# prepare and execute
PREPARE statement FROM @sql;
EXECUTE statement;

To sum up: UUid is used to uniquely identify applications. Each application has a unique UUid

So, use the same UUid for each device

This is what I came up with for a gradle build script:

task doLast {
    ext.FindFile = { list, curPath ->
        def files = file(curPath).listFiles().sort()

        files.each {  File file ->

            if (file.isFile()) {
                list << file
            }
            else {
                list << file  // If you want the directories in the list

                list = FindFile( list, file.path) 
            }
        }
        return list
    }

    def list = []
    def theFile = FindFile(list, "${project.projectDir}")

    list.each {
        println it.path
    }
}

Other alternative, perhaps not as elegant as the use of bind, but it is valid for events in a loop

for (var key in catalog){
    document.getElementById(key).my_id = key
    document.getElementById(key).addEventListener('click', function(e) {
        editorContent.loadCatalogEntry(e.srcElement.my_id)
    }, false);
}

It has been tested for google chrome extensions and maybe e.srcElement must be replaced by e.source in other browsers

I found this solution using the comment posted by Imatoria but I cannot mark it as useful because I do not have enough reputation :D

Now with NodeJS >= 10.12.0, you can use fs.mkdirSync(path, { recursive: true }) fs.mkdirSync

Dim obj : Set obj = CreateObject("Scripting.FileSystemObject")
Dim outFile : Set outFile = obj.CreateTextFile("listfile.txt")
Dim inFile: Set inFile = obj.OpenTextFile("listfile.txt")

' read file
data = inFile.ReadAll
inFile.Close

' write file
outFile.write (data)
outFile.Close

That's a bullet: •

A simple way to do what OP desires in core JS.

document.getElementById(parent.id).children[child.id];

I'd refrain from using floats for this sort of thing; I'd rather use inline-block.

Some more points to consider:

• Inline styles are bad for maintainability
• You shouldn't have spaces in selector names
• You missed some important HTML tags, like <head> and <body>
• You didn't include a doctype

Here's a better way to format your document:

<!DOCTYPE html>
<html>
<head>
<title>Website Title</title>
<style type="text/css">
* {margin: 0; padding: 0;}
#container {height: 100%; width:100%; font-size: 0;}
#left, #middle, #right {display: inline-block; *display: inline; zoom: 1; vertical-align: top; font-size: 12px;}
#left {width: 25%; background: blue;}
#middle {width: 50%; background: green;}
#right {width: 25%; background: yellow;}
</style>
</head>
<body>
<div id="container">
    <div id="left">Left Side Menu</div>
    <div id="middle">Random Content</div>
    <div id="right">Right Side Menu</div>
</div>
</body>
</html>

Here's a jsFiddle for good measure.

I like the aliases too ... however, I've had issues with MySQLCOM for start ... it fails silently ... My workaround is akin to the others ... ~/.bash_aliases

alias mysqlstart='sudo /usr/local/mysql/support-files/mysql.server start'
alias mysqlstop='sudo /usr/local/mysql/support-files/mysql.server stop' 

Use boost::filesystem, that will give you a portable way of doing those kinds of things and abstract away all ugly details for you.

A hackish perl solution can be like this. It's nice because it doesn't load all the file in memory, prints intermediate temp files, and then uses the all-wonderful paste

#!/usr/bin/perl
use warnings;
use strict;

my $counter;
open INPUT, "<$ARGV[0]" or die ("Unable to open input file!");
while (my $line = <INPUT>) {
    chomp $line;
    my @array = split ("\t",$line);
    open OUTPUT, ">temp$." or die ("unable to open output file!");
    print OUTPUT join ("\n",@array);
    close OUTPUT;
    $counter=$.;
}
close INPUT;

# paste files together
my $execute = "paste ";
foreach (1..$counter) {
    $execute.="temp$counter ";
}
$execute.="> $ARGV[1]";
system $execute;

For MySql 5.6 installed from DMG on Mavericks

sudo ln -s /usr/local/mysql-5.6.14-osx10.7-x86_64/lib/libmysqlclient.18.dylib /usr/lib/libmysqlclient.18.dylib

The best way I found to do this was to use a custom dictionary class as explained in this post: https://stackoverflow.com/a/14620633/8484485

If iPython autocompletion support is needed, simply define the dir() function like this:

class AttrDict(dict):
    def __init__(self, *args, **kwargs):
        super(AttrDict, self).__init__(*args, **kwargs)
        self.__dict__ = self
    def __dir__(self):
        return self.keys()

You then define your pseudo struct like so: (this one is nested)

my_struct=AttrDict ({
    'com1':AttrDict ({
        'inst':[0x05],
        'numbytes':2,
        'canpayload':False,
        'payload':None
    })
})

You can then access the values inside my_struct like this:

print(my_struct.com1.inst)

=>[5]

This works using grep without needing to use perl or find.

grep -rli 'old-word' * | xargs -i@ sed -i 's/old-word/new-word/g' @

Simple way to display pdf files from database and we can download it.
$resume is pdf file name which comes from database.
../resume/filename is path of folder where your file is stored.

<a href="../resumes/<?php echo $resume; ?>"/><?php echo $resume; ?></a>

You can use the by() function:

by(dataFrame, seq_len(nrow(dataFrame)), function(row) dostuff)

But iterating over the rows directly like this is rarely what you want to; you should try to vectorize instead. Can I ask what the actual work in the loop is doing?

Normally yes, .gitignore is useful for everyone who wants to work with the repository. On occasion you'll want to ignore more private things (maybe you often create LOG or something. In those cases you probably don't want to force that on anyone else.

For the checked out branch, in the case the commit you want to point to is ahead of the current branch (which should be the case unless you want to undo the last commits of the current branch), you can simply do:

git merge --ff-only <commit>

This makes a softer alternative to git reset --hard, and will fail if you are not in the case described above.

To do the same thing for a non checked out branch, the equivalent would be:

git push . <commit>:<branch>

You could also change resolution of your bluestacks emulator. For example from 800x1280 to 1280x800

Here are instructions for how to change the screen resolution.

To change screen resolution in BlueStacks Android emulator you need to edit two registry items:

1. Run regedit.exe

2. Set new resolution (in decimal):

HKEY_LOCAL_MACHINE\SOFTWARE\BlueStacks\Guests\Android\FrameBuffer\0\Height

and

HKEY_LOCAL_MACHINE\SOFTWARE\BlueStacks\Guests\Android\FrameBuffer\0\Width

Kill all BlueStacks processes.

Restart BlueStacks

Access the database as the administrator user (root maybe).

Check current SQL_mode

mysql> SELECT @@sql_mode;

To set a new sql_mode, exit the database, create a file

nano /etc/mysql/conf.d/<filename>.cnf 

with your sql_mode content

[mysqld]
sql_mode=NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

Restart Mysql

mysql> sudo service mysql stop
mysql> sudo service mysql start

We create a file in the folder /etc/mysql/conf.d/ because in the main config file /etc/mysql/my.cnf the command is written to include all the settings files from the folder /etc/mysql/conf.d/

I have case to have some bottom border between pictures in div container and the best one line code was - border-bottom-style: inset;

Your regex "sentence(.*)" is right. To retrieve the contents of the group in parenthesis, you would call:

Pattern p = Pattern.compile( "sentence(.*)" );
Matcher m = p.matcher( "some lame sentence that is awesome" );
if ( m.find() ) {
   String s = m.group(1); // " that is awesome"
}

Note the use of m.find() in this case (attempts to find anywhere on the string) and not m.matches() (would fail because of the prefix "some lame"; in this case the regex would need to be ".*sentence(.*)")

I came across this error message through a silly mistake. A classic example of Python giving you plenty of room to make a fool of yourself. Observe:

class DOH(object):
def __init__(self, property=None):
    self.property=property

def property():
    return property

x = DOH(1)
print(x.property())

Results

$ python3 t.py
Traceback (most recent call last):
  File "t.py", line 9, in <module>
    print(x.property())
TypeError: 'int' object is not callable

The problem here of course is that the function is overwritten with a property.

In order to hide the default radio button, I'd suggest to remove the button instead of making it transparent as all visual feedback is handled by the drawable background :

android:button="@null"

Also it would be better to use styles as there are several radio buttons :

<RadioButton style="@style/RadioButtonStyle" ... />

<style name="RadioButtonStyle" parent="@android:style/Widget.CompoundButton">
    <item name="android:background">@drawable/customButtonBackground</item>
    <item name="android:button">@null</item>
</style>

You'll need the Seslyn customButtonBackground drawable too.

Looking into the actual implementation of UrlBasedViewResolver and RedirectView the redirect will always be contextRelative if your redirect target starts with /. So also sending a //yahoo.com/path/to/resource wouldn't help to get a protocol relative redirect.

So to achieve what you are trying you could do something like:

@RequestMapping(method = RequestMethod.POST)
public String processForm(HttpServletRequest request, LoginForm loginForm, 
                          BindingResult result, ModelMap model) 
{
    String redirectUrl = request.getScheme() + "://www.yahoo.com";
    return "redirect:" + redirectUrl;
}

Sometimes when using open(filepath) in which filepath actually is not a file would get the same error, so firstly make sure the file you're trying to open exists:

import os
assert os.path.isfile(filepath)

You can only include a script file in an HTML page, not in another script file. That said, you can write JavaScript which loads your "included" script into the same page:

var imported = document.createElement('script');
imported.src = '/path/to/imported/script';
document.head.appendChild(imported);

There's a good chance your code depends on your "included" script, however, in which case it may fail because the browser will load the "imported" script asynchronously. Your best bet will be to simply use a third-party library like jQuery or YUI, which solves this problem for you.

// jQuery
$.getScript('/path/to/imported/script.js', function()
{
    // script is now loaded and executed.
    // put your dependent JS here.
});

This saved my life--->

1. set this line

   ListView.setDescendantFocusability(ViewGroup.FOCUS_AFTER_DESCENDANTS);

2. Then in your manifest in activity tag type this-->

   <activity android:windowSoftInputMode="adjustPan">

Your usual intent

I could see $.ajax is removed from jQuery slim 3.2.1

From the jQuery docs

You can also use the slim build, which excludes the ajax and effects modules

Below is the comment from the slim version with the features removed

/*! jQuery v3.2.1 -ajax,-ajax/jsonp,-ajax/load,-ajax/parseXML,-ajax/script,-ajax/var/location,-ajax/var/nonce,-ajax/var/rquery,-ajax/xhr,-manipulation/_evalUrl,-event/ajax,-effects,-effects/Tween,-effects/animatedSelector | (c) JS Foundation and other contributors | jquery.org/license */

If you want to add a directory and all the files which are located inside it recursively, Go to the directory where the directory you want to add is located.

$ cd directory
$ git add directoryname

Don't use Date, use Calendar:

// Beware: months are zero-based and no out of range errors are reported
Calendar date = new GregorianCalendar(2012, 9, 5);
int year = date.get(Calendar.YEAR);  // 2012
int month = date.get(Calendar.MONTH);  // 9 - October!!!
int day = date.get(Calendar.DAY_OF_MONTH);  // 5

It supports time as well:

Calendar dateTime = new GregorianCalendar(2012, 3, 4, 15, 16, 17);
int hour = dateTime.get(Calendar.HOUR_OF_DAY);  // 15
int minute = dateTime.get(Calendar.MINUTE);  // 16
int second = dateTime.get(Calendar.SECOND);  // 17

The problem with using height:100% is that it will be 100% of the page instead of 100% of the window (as you would probably expect it to be). This will cause the problem that you're seeing, because the non-fixed content is long enough to include the fixed content with 100% height without requiring a scroll bar. The browser doesn't know/care that you can't actually scroll that bar down to see it

You can use fixed to accomplish what you're trying to do.

.fixed-content {
    top: 0;
    bottom:0;
    position:fixed;
    overflow-y:scroll;
    overflow-x:hidden;
}

This fork of your fiddle shows my fix: http://jsfiddle.net/strider820/84AsW/1/

Without any jQuery:

function decodeEntities(encodedString) {_x000D_
  var textArea = document.createElement('textarea');_x000D_
  textArea.innerHTML = encodedString;_x000D_
  return textArea.value;_x000D_
}_x000D_
_x000D_
console.log(decodeEntities('1 & 2')); // '1 & 2'

This works similarly to the accepted answer, but is safe to use with untrusted user input.

Security issues in similar approaches

As noted by Mike Samuel, doing this with a <div> instead of a <textarea> with untrusted user input is an XSS vulnerability, even if the <div> is never added to the DOM:

function decodeEntities(encodedString) {_x000D_
  var div = document.createElement('div');_x000D_
  div.innerHTML = encodedString;_x000D_
  return div.textContent;_x000D_
}_x000D_
_x000D_
// Shows an alert_x000D_
decodeEntities('<img src="nonexistent_image" onerror="alert(1337)">')

However, this attack is not possible against a <textarea> because there are no HTML elements that are permitted content of a <textarea>. Consequently, any HTML tags still present in the 'encoded' string will be automatically entity-encoded by the browser.

function decodeEntities(encodedString) {_x000D_
    var textArea = document.createElement('textarea');_x000D_
    textArea.innerHTML = encodedString;_x000D_
    return textArea.value;_x000D_
}_x000D_
_x000D_
// Safe, and returns the correct answer_x000D_
console.log(decodeEntities('<img src="nonexistent_image" onerror="alert(1337)">'))

Warning: Doing this using jQuery's .html() and .val() methods instead of using .innerHTML and .value is also insecure* for some versions of jQuery, even when using a textarea. This is because older versions of jQuery would deliberately and explicitly evaluate scripts contained in the string passed to .html(). Hence code like this shows an alert in jQuery 1.8:

//<!-- CDATA_x000D_
// Shows alert_x000D_
$("<textarea>")_x000D_
.html("<script>alert(1337);</script>")_x000D_
.text();_x000D_
_x000D_
//-->

Props can change when a component's parent renders the component again with different properties. I think this is mostly an optimization so that no new component needs to be instantiated.

Dictionary class is not optimized for this case, but if you really wanted to do it (in C# 2.0), you can do:

public List<TKey> GetKeysFromValue<TKey, TVal>(Dictionary<TKey, TVal> dict, TVal val)
{
   List<TKey> ks = new List<TKey>();
   foreach(TKey k in dict.Keys)
   {
      if (dict[k] == val) { ks.Add(k); }
   }
   return ks;
}

I prefer the LINQ solution for elegance, but this is the 2.0 way.

In my opinion, deferreds/promises (as you have mentionned) is the way to go, rather than using timeouts.

Here is an example I have just written to demonstrate how you could do it using deferreds/promises.

Take some time to play around with deferreds. Once you really understand them, it becomes very easy to perform asynchronous tasks.

Hope this helps!

$(function(){
    function1().done(function(){

Preliminary code

import glob
import fnmatch
import pathlib
import os

pattern = '*.py'
path = '.'

Solution 1 - use "glob"

# lookup in current dir
glob.glob(pattern)

In [2]: glob.glob(pattern)
Out[2]: ['wsgi.py', 'manage.py', 'tasks.py']

Solution 2 - use "os" + "fnmatch"

Variant 2.1 - Lookup in current dir

# lookup in current dir
fnmatch.filter(os.listdir(path), pattern)

In [3]: fnmatch.filter(os.listdir(path), pattern)
Out[3]: ['wsgi.py', 'manage.py', 'tasks.py']

Variant 2.2 - Lookup recursive

# lookup recursive
for dirpath, dirnames, filenames in os.walk(path):

    if not filenames:
        continue

    pythonic_files = fnmatch.filter(filenames, pattern)
    if pythonic_files:
        for file in pythonic_files:
            print('{}/{}'.format(dirpath, file))

Result

./wsgi.py
./manage.py
./tasks.py
./temp/temp.py
./apps/diaries/urls.py
./apps/diaries/signals.py
./apps/diaries/actions.py
./apps/diaries/querysets.py
./apps/library/tests/test_forms.py
./apps/library/migrations/0001_initial.py
./apps/polls/views.py
./apps/polls/formsets.py
./apps/polls/reports.py
./apps/polls/admin.py

Solution 3 - use "pathlib"

# lookup in current dir
path_ = pathlib.Path('.')
tuple(path_.glob(pattern))

# lookup recursive
tuple(path_.rglob(pattern))

Notes:

1. Tested on the Python 3.4
2. The module "pathlib" was added only in the Python 3.4
3. The Python 3.5 added a feature for recursive lookup with glob.glob https://docs.python.org/3.5/library/glob.html#glob.glob. Since my machine is installed with Python 3.4, I have not tested that.

If you have no changes, you can always be really thorough and/or lazy and do...

rm -rf *
svn update

But, no really, do not do that unless you are really sure that the nuke-from-space option is what you want!! This has the advantage of also nuking all build cruft, temporary files, and things that SVN ignores.

The more correct solution is to use the revert command:

svn revert -R .

The -R causes subversion to recurse and revert everything in and below the current working directory.

I found this official tool from facebook developer page, this page will you following information related to access token - App ID, Type, App-Scoped,User last installed this app via, Issued, Expires, Data Access Expires, Valid, Origin, Scopes. Just need access token.

Environment variables may also provide a useful means -- COMPUTERNAME on Windows, HOSTNAME on most modern Unix/Linux shells.

See: https://stackoverflow.com/a/17956000/768795

I'm using these as "supplementary" methods to InetAddress.getLocalHost().getHostName(), since as several people point out, that function doesn't work in all environments.

Runtime.getRuntime().exec("hostname") is another possible supplement. At this stage, I haven't used it.

import java.net.InetAddress;
import java.net.UnknownHostException;

// try InetAddress.LocalHost first;
//      NOTE -- InetAddress.getLocalHost().getHostName() will not work in certain environments.
try {
    String result = InetAddress.getLocalHost().getHostName();
    if (StringUtils.isNotEmpty( result))
        return result;
} catch (UnknownHostException e) {
    // failed;  try alternate means.
}

// try environment properties.
//      
String host = System.getenv("COMPUTERNAME");
if (host != null)
    return host;
host = System.getenv("HOSTNAME");
if (host != null)
    return host;

// undetermined.
return null;

Using furl and regex (python 3)

>>> import re
>>> import furl
>>> p = re.compile(r'(\/)+')
>>> url = furl.furl('/media/path').add(path='/js/foo.js').url
>>> url
'/media/path/js/foo.js'
>>> p.sub(r"\1", url)
'/media/path/js/foo.js'
>>> url = furl.furl('/media/path').add(path='js/foo.js').url
>>> url
'/media/path/js/foo.js'
>>> p.sub(r"\1", url)
'/media/path/js/foo.js'
>>> url = furl.furl('/media/path/').add(path='js/foo.js').url
>>> url
'/media/path/js/foo.js'
>>> p.sub(r"\1", url)
'/media/path/js/foo.js'
>>> url = furl.furl('/media///path///').add(path='//js///foo.js').url
>>> url
'/media///path/////js///foo.js'
>>> p.sub(r"\1", url)
'/media/path/js/foo.js'

map3 = new HashMap<>();

map3.putAll(map1);
map3.putAll(map2);

HTML event handler code behaves like the body of a JavaScript function. Many languages such as C or Perl implicitly return the value of the last expression evaluated in the function body. JavaScript doesn't, it discards it and returns undefined unless you write an explicit returnEXPR.

The size of arrays in Java cannot be changed. So, technically you cannot remove any elements from the array.

One way to simulate removing an element from the array is to create a new, smaller array, and then copy all of the elements from the original array into the new, smaller array.

String[] yourArray = Arrays.copyOfRange(oldArr, 1, oldArr.length);

However, I would not suggest the above method. You should really be using a List<String>. Lists allow you to add and remove items from any index. That would look similar to the following:

List<String> list = new ArrayList<String>(); // or LinkedList<String>();
list.add("Stuff");
// add lots of stuff
list.remove(0); // removes the first item

From the research I have done, if you are targeting Nvidia GPUs and have decided to use CUDA over OpenCL, I found three ways to use the CUDA API in java.

1. JCuda (or alternative)- http://www.jcuda.org/. This seems like the best solution for the problems I am working on. Many of libraries such as CUBLAS are available in JCuda. Kernels are still written in C though.
2. JNI - JNI interfaces are not my favorite to write, but are very powerful and would allow you to do anything CUDA can do.
3. JavaCPP - This basically lets you make a JNI interface in Java without writing C code directly. There is an example here: What is the easiest way to run working CUDA code in Java? of how to use this with CUDA thrust. To me, this seems like you might as well just write a JNI interface.

All of these answers basically are just ways of using C/C++ code in Java. You should ask yourself why you need to use Java and if you can't do it in C/C++ instead.

If you like Java and know how to use it and don't want to work with all the pointer management and what-not that comes with C/C++ then JCuda is probably the answer. On the other hand, the CUDA Thrust library and other libraries like it can be used to do a lot of the pointer management in C/C++ and maybe you should look at that.

If you like C/C++ and don't mind pointer management, but there are other constraints forcing you to use Java, then JNI might be the best approach. Though, if your JNI methods are just going be wrappers for kernel commands you might as well just use JCuda.

There are a few alternatives to JCuda such as Cuda4J and Root Beer, but those do not seem to be maintained. Whereas at the time of writing this JCuda supports CUDA 10.1. which is the most up-to-date CUDA SDK.

Additionally there are a few java libraries that use CUDA, such as deeplearning4j and Hadoop, that may be able to do what you are looking for without requiring you to write kernel code directly. I have not looked into them too much though.

Some optimizing compilers will be able to do better loop unrolling with a for loop, but odds are that if you're doing something that can be unrolled, a compiler smart enough to unroll it is probably also smart enough to interpret the loop condition of your while loop as something it can unroll as well.

Jonas's answer does not change the font size of the axes. Sergeyf's answer does not work when there are multiple subplots.

Here is a modification of their answers that works for me when I have multiple subplots:

set(findall(gcf,'type','axes'),'fontsize',30)
set(findall(gcf,'type','text'),'fontSize',30) 

You have to also add the "navbar-brand" class to your image a container, also you have to include it inside the .navbar-inner container, like so:

 <div class="navbar navbar-fixed-top">
   <div class="navbar-inner">
     <div class="container">
        <a class="navbar-brand" href="index.html"> <img src="images/57x57x300.jpg"></a>
     </div>
   </div>
 </div>

Since nobody has mentioned it, I'd like to add that Facebook chat is written in Erlang.

You need to make sure and have the following:

#include <windows.h>

and not this:

#include "windows.h"

If that's not the problem, then check RichieHindle's response.

In order to get the popup exactly centered, it's a simple matter of applying a negative top margin of half the div height, and a negative left margin of half the div width. For this example, like so:

.div {
    position: fixed;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
    width: 50%;
}

  Check balanced parenthesis or brackets with stack-- 
  var excp = "{{()}[{a+b+b}][{(c+d){}}][]}";
   var stk = [];   
   function bracket_balance(){
      for(var i=0;i<excp.length;i++){
          if(excp[i]=='[' || excp[i]=='(' || excp[i]=='{'){
             stk.push(excp[i]);
          }else if(excp[i]== ']' && stk.pop() != '['){
             return false;
          }else if(excp[i]== '}' && stk.pop() != '{'){

            return false;
          }else if(excp[i]== ')' && stk.pop() != '('){

            return false;
          }
      }

      return true;
   }

  console.log(bracket_balance());
  //Parenthesis are balance then return true else false

Database files cannot be reduced in size. While "repairing" database, it is only possible for mongo server to delete some of its files. If large amount of data has been deleted, mongo server will "release" (delete), during repair, some of its existing files.

You can find some technical comparison on npmcompare

Comparing browserify vs. grunt vs. gulp vs. webpack

As you can see webpack is very well maintained with a new version coming out every 4 days on average. But Gulp seems to have the biggest community of them all (with over 20K stars on Github) Grunt seems a bit neglected (compared to the others)

So if need to choose one over the other i would go with Gulp

You can use this extensions to improve substringWithRange

Swift 2.3

extension String
{   
    func substringWithRange(start: Int, end: Int) -> String
    {
        if (start < 0 || start > self.characters.count)
        {
            print("start index \(start) out of bounds")
            return ""
        }
        else if end < 0 || end > self.characters.count
        {
            print("end index \(end) out of bounds")
            return ""
        }
        let range = Range(start: self.startIndex.advancedBy(start), end: self.startIndex.advancedBy(end))
        return self.substringWithRange(range)
    }

    func substringWithRange(start: Int, location: Int) -> String
    {
        if (start < 0 || start > self.characters.count)
        {
            print("start index \(start) out of bounds")
            return ""
        }
        else if location < 0 || start + location > self.characters.count
        {
            print("end index \(start + location) out of bounds")
            return ""
        }
        let range = Range(start: self.startIndex.advancedBy(start), end: self.startIndex.advancedBy(start + location))
        return self.substringWithRange(range)
    }
}

Swift 3

extension String
{
    func substring(start: Int, end: Int) -> String
    {
        if (start < 0 || start > self.characters.count)
        {
            print("start index \(start) out of bounds")
            return ""
        }
        else if end < 0 || end > self.characters.count
        {
            print("end index \(end) out of bounds")
            return ""
        }
        let startIndex = self.characters.index(self.startIndex, offsetBy: start)
        let endIndex = self.characters.index(self.startIndex, offsetBy: end)
        let range = startIndex..<endIndex

        return self.substring(with: range)
    }

    func substring(start: Int, location: Int) -> String
    {
        if (start < 0 || start > self.characters.count)
        {
            print("start index \(start) out of bounds")
            return ""
        }
        else if location < 0 || start + location > self.characters.count
        {
            print("end index \(start + location) out of bounds")
            return ""
        }
        let startIndex = self.characters.index(self.startIndex, offsetBy: start)
        let endIndex = self.characters.index(self.startIndex, offsetBy: start + location)
        let range = startIndex..<endIndex

        return self.substring(with: range)
    }
}

Usage:

let str = "Hello, playground"

let substring1 = str.substringWithRange(0, end: 5) //Hello
let substring2 = str.substringWithRange(7, location: 10) //playground

you can't hash a list like that. try this instead, it uses tuples

d[tuple([i for i in range(1,11)])] = True

C# This is performing great:

static readonly Regex _base64RegexPattern = new Regex(BASE64_REGEX_STRING, RegexOptions.Compiled);

private const String BASE64_REGEX_STRING = @"^[a-zA-Z0-9\+/]*={0,3}$";

private static bool IsBase64(this String base64String)
{
    var rs = (!string.IsNullOrEmpty(base64String) && !string.IsNullOrWhiteSpace(base64String) && base64String.Length != 0 && base64String.Length % 4 == 0 && !base64String.Contains(" ") && !base64String.Contains("\t") && !base64String.Contains("\r") && !base64String.Contains("\n")) && (base64String.Length % 4 == 0 && _base64RegexPattern.Match(base64String, 0).Success);
    return rs;
}

You might be interested in itertools.product, which returns an iterable yielding tuples of values from all the iterables you pass it. That is, itertools.product(A, B) yields all values of the form (a, b), where the a values come from A and the b values come from B. For example:

import itertools

A = [50, 60, 70]
B = [0.1, 0.2, 0.3, 0.4]

print [a + b for a, b in itertools.product(A, B)]

This prints:

[50.1, 50.2, 50.3, 50.4, 60.1, 60.2, 60.3, 60.4, 70.1, 70.2, 70.3, 70.4]

Notice how the final argument passed to itertools.product is the "inner" one. Generally, itertools.product(a0, a1, ... an) is equal to [(i0, i1, ... in) for in in an for in-1 in an-1 ... for i0 in a0]

These are positional arguments of the script.

Executing

./script.sh Hello World

Will make

$0 = ./script.sh
$1 = Hello
$2 = World

Note

If you execute ./script.sh, $0 will give output ./script.sh but if you execute it with bash script.sh it will give output script.sh.

You need to set JDK 1.5 to your project and also all dependent project or jar file should also compiled with JDK 1.5

To adjust the length of the samples:

set key samplen X

(default is 4)

To adjust the vertical spacing of the samples:

set key spacing X

(default is 1.25)

and (for completeness), to adjust the fontsize:

set key font "<face>,<size>"

(default depends on the terminal)

And of course, all these can be combined into one line:

set key samplen 2 spacing .5 font ",8"

Note that you can also change the position of the key using set key at <position> or any one of the pre-defined positions (which I'll just defer to help key at this point)

The WriteXLS function from the WriteXLS package can write data to Excel.

Alternatively, write.xlsx from the xlsx package will also work.

You can use curl or wget to retrieve the raw data, or you can use w3m -dump to have a nice text representation of a web page.

$ foo=$(w3m -dump http://www.example.com/); echo $foo
You have reached this web page by typing "example.com", "example.net","example.org" or "example.edu" into your web browser. These domain names are reserved for use in documentation and are not available for registration. See RFC 2606, Section 3.

I do not see Python answers here. You can script folder upload using Python/boto3. Here's how to recursively get all file names from directory tree:

def recursive_glob(treeroot, extention):
    results = [os.path.join(dirpath, f)
        for dirpath, dirnames, files in os.walk(treeroot)
        for f in files if f.endswith(extention)]
    return results

Here's how to upload a file to S3 using Python/boto:

k = Key(bucket)
k.key = s3_key_name
k.set_contents_from_file(file_handle, cb=progress, num_cb=20, reduced_redundancy=use_rr )

I used these ideas to write Directory-Uploader-For-S3

What you want is this constructor: std::string ( const string& str, size_t pos, size_t n = npos ), passing pos as 0. Your const char* c-style string will get implicitly cast to const string for the first parameter.

const char *c_style = "012abd";
std::string cpp_style = new std::string(c_style, 0, 10);

var singleClickTimer = 0; //define a var to hold timer event in parent scope
jqueryElem.click(function(e){ //using jquery click handler
    if (e.detail == 1) { //ensure this is the first click
        singleClickTimer = setTimeout(function(){ //create a timer
            alert('single'); //run your single click code
        },250); //250 or 1/4th second is about right
    }
});

jqueryElem.dblclick(function(e){ //using jquery dblclick handler
    clearTimeout(singleClickTimer); //cancel the single click
    alert('double'); //run your double click code
});

// This code was tested by me (Helio Barbosa)

    // this directory (../backup) is for try only.
    // it is necessary create it and put files into him.

    $hDir = '../backup';
    if ($handle = opendir( $hDir )) {
        echo "Manipulador de diretório: $handle\n";
        echo "Arquivos:\n";

        /* Esta é a forma correta de varrer o diretório */
        /* Here is the correct form to do find files into the directory */
        while (false !== ($file = readdir($handle))) {
            // echo($file . "</br>");
            $filepath = $hDir . "/" . $file ;
            // echo( $filepath . "</br>" );
            if(is_file($filepath))
            {
                echo("Deleting:" . $file . "</br>");
                unlink($filepath);
            }           
        }

        closedir($handle);
    }

This is achieved through URL rewriting, not through URL obfuscating, which can't be done.

Another way to do this, as has been mentioned is by changing the hashtag, with

window.location.hash = "/2131/"

Try to slightly modify your code:

Sub forEachWs()
    Dim ws As Worksheet
    For Each ws In ActiveWorkbook.Worksheets
        Call resizingColumns(ws)
    Next
End Sub

Sub resizingColumns(ws As Worksheet)
    With ws
        .Range("A:A").ColumnWidth = 20.14
        .Range("B:B").ColumnWidth = 9.71
        .Range("C:C").ColumnWidth = 35.86
        .Range("D:D").ColumnWidth = 30.57
        .Range("E:E").ColumnWidth = 23.57
        .Range("F:F").ColumnWidth = 21.43
        .Range("G:G").ColumnWidth = 18.43
        .Range("H:H").ColumnWidth = 23.86
        .Range("i:I").ColumnWidth = 27.43
        .Range("J:J").ColumnWidth = 36.71
        .Range("K:K").ColumnWidth = 30.29
        .Range("L:L").ColumnWidth = 31.14
        .Range("M:M").ColumnWidth = 31
        .Range("N:N").ColumnWidth = 41.14
        .Range("O:O").ColumnWidth = 33.86
    End With
End Sub

Note, resizingColumns routine takes parametr - worksheet to which Ranges belongs.

Basically, when you're using Range("O:O") - code operats with range from ActiveSheet, that's why you should use With ws statement and then .Range("O:O").

And there is no need to use global variables (unless you are using them somewhere else)

Use permission symbols instead of numbers

Your problem would have been avoided if you had used the more semantically named permission symbols rather than raw magic numbers, e.g. for 664:

#!/usr/bin/env python3

import os
import stat

os.chmod(
    'myfile',
    stat.S_IRUSR |
    stat.S_IWUSR |
    stat.S_IRGRP |
    stat.S_IWGRP |
    stat.S_IROTH
)

This is documented at https://docs.python.org/3/library/os.html#os.chmod and the names are the same as the POSIX C API values documented at man 2 stat.

Another advantage is the greater portability as mentioned in the docs:

Note: Although Windows supports chmod(), you can only set the file’s read-only flag with it (via the stat.S_IWRITE and stat.S_IREAD constants or a corresponding integer value). All other bits are ignored.

chmod +x is demonstrated at: How do you do a simple "chmod +x" from within python?

Tested in Ubuntu 16.04, Python 3.5.2.

The keys are maintained with the removed key missing but they can be rearranged by doing this:

$array = array(1,2,3,4,5);
unset($array[2]);
$arranged = array_values($array);
print_r($arranged);

Outputs:

Array
(
    [0] => 1
    [1] => 2
    [2] => 4
    [3] => 5
)

Notice that if we do the following without rearranging:

unset($array[2]);
$array[]=3;

The index of the value 3 will be 5 because it will be pushed to the end of the array and will not try to check or replace missing index. This is important to remember when using FOR LOOP with index access.

The almighty switch works well here:

'one
two
three' > file

$regex = '^t'

switch -regex -file file { 
  $regex { "line is $_" } 
}

Output:

line is two
line is three

Sure you can:

Option Explicit

'***** User defined type
Public Type MyType
     MyInt As Integer
     MyString As String
     MyDoubleArr(2) As Double
End Type

All this tricks just look (more or less) as local functions, but they don't work like that. In a local function you can use local variables of it's super functions. It's kind of semi-globals. Non of these tricks can do that. The closest is the lambda trick from c++0x, but it's closure is bound in definition time, not the use time.

Necromancing, just in case all the links go dark:

1. Add a group to your report
   Also, be advised to set the sort order of the group expression here, so the tabs will be alphabetically sorted (or however you want it sorted).
   
   

   • 'Zeilengruppe' means 'Target group'
   • 'Gruppeneigenschaften' means 'Group properties'

2. Set the page break in the group properties

   • 'Seitenumbruche' means 'Page break'
   • 'Zwischen den einzelnen Instanzen einer Gruppe' means 'Between the individual instances of a group'

3. Now you need to set the PageName of the Tablix Member (group), NOT the PageName of the Tablix itselfs.
   If you got the right object, if will say "Tablix Member" (Tablix-Element in German) in the title box of the properties grid. If it's the wrong object, it will say only "table/tablix" (without member) in the property grid's title box.
   

4. Note: If you get the tablix instead of the tablix member, it will put the same tab name in every tab, followed by a (tabNum)! If that happens, you now know what the problem is.

If I'm not using any category then how can I use this code? Actually, I want to use this code for custom post type.

The second sample assigns a unique ID to the element in question. This element can then be manipulated or accessed using DHTML.

The first one, on the other hand, sets a named location within the document, akin to a bookmark. Attached to an "anchor", it makes perfect sense.

You can find the commit id related to each commit in the commits section of GitHub/BitBucket/Gitlab. Its very simple, suppose your commit id is 5889575 then if you want to go back to this part in your code then you simply need to type

git checkout 5889575 .

This will take you to that point of time in your code.

The easiest way to customize the integrated facebook button for both java and kotlin

Try this

Window > Show View > Package Explorer

it will display the hidden 'Package Explorer' on your eclipse IDE.

• 'Window' is in your Eclipse' menubar.

I have a full discussion of events and delegates in my events article. For the simplest kind of event, you can just declare a public event and the compiler will create both an event and a field to keep track of subscribers:

public event EventHandler Foo;

If you need more complicated subscription/unsubscription logic, you can do that explicitly:

public event EventHandler Foo
{
    add
    {
        // Subscription logic here
    }
    remove
    {
        // Unsubscription logic here
    }
}

if (function_exists('header_remove')) {
    header_remove('X-Powered-By'); // PHP 5.3+
} else {
    @ini_set('expose_php', 'off');
}

You can do it this way. It needs to go in the maven format:

repositories {
  maven { url uri('folderName')}
}

And then your AAR needs to go in a folder structure for a group id "com.example":

folderName/
  com/
    example/
       verion/
          myaar-version.aar

Then reference as a dependency:

compile 'com.example:myaar:version@aar'

Where version is the version of your aar file (ie, 3.0, etc)

You could use JavaScript and trigger the hidden file input when the button input has been clicked.

http://jsfiddle.net/gregorypratt/dhyzV/ - simple

http://jsfiddle.net/gregorypratt/dhyzV/1/ - fancier with a little JQuery

Or, you could style a div directly over the file input and set pointer-events in CSS to none to allow the click events to pass through to the file input that is "behind" the fancy div. This only works in certain browsers though; http://caniuse.com/pointer-events

for me this error was actually caused by a field falsely declared as public instead of private.

Another simple solution is list(np.where(df['b'].isnull())[0])

You will have to provide the entire user dn in SECURITY_PRINCIPAL

like this

env.put(Context.SECURITY_PRINCIPAL, "cn=username,ou=testOu,o=test"); 

Perfectly fine.
You can't instantiate abstract classes.. but abstract classes can be used to house common implementations for m1() and m3().
So if m2() implementation is different for each implementation but m1 and m3 are not. You could create different concrete IAnything implementations with just the different m2 implementation and derive from AbstractThing -- honoring the DRY principle. Validating if the interface is completely implemented for an abstract class is futile..

Update: Interestingly, I find that C# enforces this as a compile error. You are forced to copy the method signatures and prefix them with 'abstract public' in the abstract base class in this scenario.. (something new everyday:)

Actually CSRF is a session based token. Add your route in a route group and add a middleware which control the sessions.

web is a default middleware in laravel and it can controls the session requests.

Route::group(array('middleware' => ['web']), function () {
  Route::post('/foo', function () {
     echo 1;
     return;
  });
});

I had an outdated symlink that was preventing me from accessing the proper bin. I had also recently gone through a node upgrade which means a lot of my newer bins were available in a different folder with what i think was a lower priority

Here is what worked for me:

yarn -v 
> 1.15.2

which yarn
> /Users/lfender/.yarn/bin/yarn 

rm -rf /Users/lfender/.yarn/bin/yarn
npm uninstall --global yarn; npm install --global yarn

> + [email protected]
> added 1 package in 0.179s

which yarn
> /Users/lfender/.nvm/versions/node/v12.2.0/bin/yarn

yarn -v
> 1.16.0

If you are not using NVM, the location of your bin installs are likely to be unique to your system

From there, I've switched to doing yarn policies set-version as outlined here https://stackoverflow.com/a/55278430/1426788 to define my yarn version at the repo level

Windows 10 Home Edition does not have Local Users and Groups option so that is the reason you aren't able to see that in Computer Management.

You can use User Accounts by pressing Window+R, typing netplwiz and pressing OK as described here.

This is the eclipse pain in the ass UI. If you unckecked previously some components because they have broken dependencies, it blocks in the license. You have to unselect them in the first step.

Note that avoid to use the update feature of Eclipse it broke all my plugin, I had to delete my ./eclipse folder and reinstall all.

There are two ways to solve the issue "cannot be resolved to a type ":

1. For non maven project, add jars manually in a folder and add it in java build path. This would solve the compilation errors.
2. For maven project, right click on the project and go to maven -> update project. Select all the projects where you are getting compilation errors and also check "Force update of snapshots/releases". This will update the project and fix the compilation errors.

When using the Spring Framework (either as a collection of utilities or container - you do not need to use the latter functionality) you can easily use the Resource abstraction.

Resource resource = new ClassPathResource("com/example/Foo.class");

Through the Resource interface you can access the resource as InputStream, URL, URI or File. Changing the resource type to e.g. a file system resource is a simple matter of changing the instance.

JavaScript will get the job done.

Get all links in the document and compare their reference URLs to the document's URL. If there is a match, add a class to that link.

JavaScript

<script>
    currentLinks = document.querySelectorAll('a[href="'+document.URL+'"]')
    currentLinks.forE??ach(function(link) {
        link.className += ' current-link')
    });
</script>

One Liner Version of Above

document.querySelectorAll('a[href="'+document.URL+'"]').forE??ach(function(elem){e??lem.className += ' current-link')});

CSS

.current-link {
    color:#baada7;
}

Other Notes

Taraman's jQuery answer above only searches on [href] which will return link tags and tags other than a which rely on the href attribute. Searching on a[href='*https://urlofcurrentpage.com*'] captures only those links which meets the criteria and therefore runs faster.

In addtion, if you don't need to rely on the jQuery library, a vanilla JavaScript solution is definitely the way to go.

In C++11, the using keyword when used for type alias is identical to typedef.

7.1.3.2

A typedef-name can also be introduced by an alias-declaration. The identifier following the using keyword becomes a typedef-name and the optional attribute-specifier-seq following the identifier appertains to that typedef-name. It has the same semantics as if it were introduced by the typedef specifier. In particular, it does not define a new type and it shall not appear in the type-id.

Bjarne Stroustrup provides a practical example:

typedef void (*PFD)(double);    // C style typedef to make `PFD` a pointer to a function returning void and accepting double
using PF = void (*)(double);    // `using`-based equivalent of the typedef above
using P = [](double)->void; // using plus suffix return type, syntax error
using P = auto(double)->void // Fixed thanks to DyP

Pre-C++11, the using keyword can bring member functions into scope. In C++11, you can now do this for constructors (another Bjarne Stroustrup example):

class Derived : public Base { 
public: 
    using Base::f;    // lift Base's f into Derived's scope -- works in C++98
    void f(char);     // provide a new f 
    void f(int);      // prefer this f to Base::f(int) 

    using Base::Base; // lift Base constructors Derived's scope -- C++11 only
    Derived(char);    // provide a new constructor 
    Derived(int);     // prefer this constructor to Base::Base(int) 
    // ...
}; 

Ben Voight provides a pretty good reason behind the rationale of not introducing a new keyword or new syntax. The standard wants to avoid breaking old code as much as possible. This is why in proposal documents you will see sections like Impact on the Standard, Design decisions, and how they might affect older code. There are situations when a proposal seems like a really good idea but might not have traction because it would be too difficult to implement, too confusing, or would contradict old code.

Here is an old paper from 2003 n1449. The rationale seems to be related to templates. Warning: there may be typos due to copying over from PDF.

First let’s consider a toy example:

template <typename T>
class MyAlloc {/*...*/};

template <typename T, class A>
class MyVector {/*...*/};

template <typename T>

struct Vec {
typedef MyVector<T, MyAlloc<T> > type;
};
Vec<int>::type p; // sample usage

The fundamental problem with this idiom, and the main motivating fact for this proposal, is that the idiom causes the template parameters to appear in non-deducible context. That is, it will not be possible to call the function foo below without explicitly specifying template arguments.

template <typename T> void foo (Vec<T>::type&);

So, the syntax is somewhat ugly. We would rather avoid the nested ::type We’d prefer something like the following:

template <typename T>
using Vec = MyVector<T, MyAlloc<T> >; //defined in section 2 below
Vec<int> p; // sample usage

Note that we specifically avoid the term “typedef template” and introduce the new syntax involving the pair “using” and “=” to help avoid confusion: we are not defining any types here, we are introducing a synonym (i.e. alias) for an abstraction of a type-id (i.e. type expression) involving template parameters. If the template parameters are used in deducible contexts in the type expression then whenever the template alias is used to form a template-id, the values of the corresponding template parameters can be deduced – more on this will follow. In any case, it is now possible to write generic functions which operate on Vec<T> in deducible context, and the syntax is improved as well. For example we could rewrite foo as:

template <typename T> void foo (Vec<T>&);

We underscore here that one of the primary reasons for proposing template aliases was so that argument deduction and the call to foo(p) will succeed.

The follow-up paper n1489 explains why using instead of using typedef:

It has been suggested to (re)use the keyword typedef — as done in the paper [4] — to introduce template aliases:

template<class T> 
    typedef std::vector<T, MyAllocator<T> > Vec;

That notation has the advantage of using a keyword already known to introduce a type alias. However, it also displays several disavantages among which the confusion of using a keyword known to introduce an alias for a type-name in a context where the alias does not designate a type, but a template; Vec is not an alias for a type, and should not be taken for a typedef-name. The name Vec is a name for the family std::vector< [bullet] , MyAllocator< [bullet] > > – where the bullet is a placeholder for a type-name. Consequently we do not propose the “typedef” syntax. On the other hand the sentence

template<class T>
    using Vec = std::vector<T, MyAllocator<T> >;

can be read/interpreted as: from now on, I’ll be using Vec<T> as a synonym for std::vector<T, MyAllocator<T> >. With that reading, the new syntax for aliasing seems reasonably logical.

I think the important distinction is made here, aliases instead of types. Another quote from the same document:

An alias-declaration is a declaration, and not a definition. An alias- declaration introduces a name into a declarative region as an alias for the type designated by the right-hand-side of the declaration. The core of this proposal concerns itself with type name aliases, but the notation can obviously be generalized to provide alternate spellings of namespace-aliasing or naming set of overloaded functions (see ? 2.3 for further discussion). [My note: That section discusses what that syntax can look like and reasons why it isn't part of the proposal.] It may be noted that the grammar production alias-declaration is acceptable anywhere a typedef declaration or a namespace-alias-definition is acceptable.

Summary, for the role of using:

• template aliases (or template typedefs, the former is preferred namewise)
• namespace aliases (i.e., namespace PO = boost::program_options and using PO = ... equivalent)
• the document says A typedef declaration can be viewed as a special case of non-template alias-declaration. It's an aesthetic change, and is considered identical in this case.
• bringing something into scope (for example, namespace std into the global scope), member functions, inheriting constructors

It cannot be used for:

int i;
using r = i; // compile-error

Instead do:

using r = decltype(i);

Naming a set of overloads.

// bring cos into scope
using std::cos;

// invalid syntax
using std::cos(double);

// not allowed, instead use Bjarne Stroustrup function pointer alias example
using test = std::cos(double);

After fighting with this for a long time, it looks like I found something that seems to work. I was optimizing the urls to not include the username (keep it as generic as possible), but the authentication dialog kept popping up:

I tried everything that came into mind, such as:

1. Enable and disable MFA (Multi Factor Authentication)
2. Create app passwords (again, with and without MFA enabled)

No matter what tools I used (including SourceTree), nothing worked. The server kept returning: "Create an app password"

Basically you must

1. Use the url including the username (e.g. https://[email protected]/...)
2. Use an app password created in bitbucket

Would be so nice if the server would have returned this in the response instead of suggesting to use an app password...

The 2nd parameter in the get call is a config object. You want something like this:

$http
    .get('accept.php', {
        params: {
            source: link,
            category_id: category
        }
     })
     .success(function (data,status) {
          $scope.info_show = data
     });

See the Arguments section of http://docs.angularjs.org/api/ng.$http for more detail

Using the syntax text_element.selectionStart we can get the starting position of the selection of a text in terms of the index of the first character of the selected text in the text_element.value and in case we want to get the same of the last character in the selection we have to use text_element.selectionEnd.

Use it as follows:

<input type=text id=t1 value=abcd>
<button onclick="alert(document.getElementById('t1').selectionStart)">check position</button>

I'm giving you the fiddle_demo

just use a property

int  _theVariable;
public int TheVariable{
  get{return _theVariable;}
  set{
    _theVariable = value; 
    if ( _theVariable == 1){
      //Do stuff here.
    }
  }
}

OK, I know at first might be a bit confusing, but display is talking about the parent element, so means when we say: display: flex;, it's about the element and when we say display:inline-flex;, is also making the element itself inline...

It's like make a div inline or block, run the snippet below and you can see how display flex breaks down to next line:

.inline-flex {_x000D_
  display: inline-flex;_x000D_
}_x000D_
_x000D_
.flex {_x000D_
  display: flex;_x000D_
}_x000D_
_x000D_
p {_x000D_
  color: red;_x000D_
}

Something that just happened to me and caused me some headaches:

I have set up a new Linux RabbitMQ server and used a shell script to set up my own custom users (not guest!).

The script had several of those "code" blocks:

rabbitmqctl add_user test test
rabbitmqctl set_user_tags test administrator
rabbitmqctl set_permissions -p / test ".*" ".*" ".*"

Very similar to the one in Gabriele's answer, so I take his code and don't need to redact passwords.

Still I was not able to log in in the management console. Then I noticed that I had created the setup script in Windows (CR+LF line ending) and converted the file to Linux (LF only), then reran the setup script on my Linux server.

... and was still not able to log in, because it took another 15 minutes until I realized that calling add_user over and over again would not fix the broken passwords (which probably ended with a CR character). I had to call change_password for every user to fix my earlier mistake:

rabbitmqctl change_password test test

(Another solution would have been to delete all users and then call the script again)

To improve upon the answer given by derobert,

You can determine what your OS connection limit is by catting nf_conntrack_max.

For example: cat /proc/sys/net/netfilter/nf_conntrack_max

You can use the following script to count the number of tcp connections to a given range of tcp ports. By default 1-65535.

This will confirm whether or not you are maxing out your OS connection limit.

Here's the script.

#!/bin/bash
OS=$(uname)

    'SunOS')
            AWK=/usr/bin/nawk

            ;;

    if ( sip ~ /:/ )
