$('html, body').animate({scrollTop: $("#page").offset().top}, 2000);

scrollTop() returns the number of pixels that are hidden from view from the scrollable area, so giving it:

$(document).height()

will actually overshoot the bottom of the page. For the scroll to actually 'stop' at the bottom of the page, the current height of the browser window needs subtracting. This will allow the use of easing if required, so it becomes:

$('html, body').animate({ 
   scrollTop: $(document).height()-$(window).height()}, 
   1400, 
   "easeOutQuint"
);

This solution worked for me

// store the currently selected tab in the hash value
    if(history.pushState) {
        window.history.pushState(null, null, '#' + id);
    }
    else {
        window.location.hash = id;
    }

// on load of the page: switch to the currently selected tab
var hash = window.location.hash;
$('#myTab a[href="' + hash + '"]').tab('show');

And my full js code is

$('#myTab a').click(function(e) {
  e.preventDefault();
  $(this).tab('show');
});

// store the currently selected tab in the hash value
$("ul.nav-tabs > li > a").on("shown.bs.tab", function(e) {
  var id = $(e.target).attr("href").substr(1);
    if(history.pushState) {
        window.history.pushState(null, null, '#' + id);
    }
    else {
        window.location.hash = id;
    }
   // window.location.hash = '#!' + id;
});

// on load of the page: switch to the currently selected tab
var hash = window.location.hash;
// console.log(hash);
$('#myTab a[href="' + hash + '"]').tab('show');

Yep, even in plain JavaScript it's pretty easy. You give an element an id and then you can use that as a "bookmark":

<div id="here">here</div>

If you want it to scroll there when a user clicks a link, you can just use the tried-and-true method:

<a href="#here">scroll to over there</a>

To do it programmatically, use scrollIntoView()

document.getElementById("here").scrollIntoView()

Combining this question with the best answer from jQuery trigger action when a user scrolls past a certain part of the page

var element_position = $('#scroll-to').offset().top;

$(window).on('scroll', function() {
    var y_scroll_pos = window.pageYOffset;
    var scroll_pos_test = element_position;

    if(y_scroll_pos > scroll_pos_test) {
        //do stuff
    }
});

UPDATE

I've improved the code so that it will trigger when the element is half way up the screen rather than at the very top. It will also trigger the code if the user hits the bottom of the screen and the function hasn't fired yet.

var element_position = $('#scroll-to').offset().top;
var screen_height = $(window).height();
var activation_offset = 0.5;//determines how far up the the page the element needs to be before triggering the function
var activation_point = element_position - (screen_height * activation_offset);
var max_scroll_height = $('body').height() - screen_height - 5;//-5 for a little bit of buffer

//Does something when user scrolls to it OR
//Does it when user has reached the bottom of the page and hasn't triggered the function yet
$(window).on('scroll', function() {
    var y_scroll_pos = window.pageYOffset;

    var element_in_view = y_scroll_pos > activation_point;
    var has_reached_bottom_of_page = max_scroll_height <= y_scroll_pos && !element_in_view;

    if(element_in_view || has_reached_bottom_of_page) {
        //Do something
    }
});

The one exception worth noting is that while you can't delete apps, the folks over at Google Play Developer Support are able to on their end if the app is both unpublished and has 0 lifetime installs. So if your app has 0 lifetime installs, you might be in luck.

First you will need unpublish the app and wait 24 hours (to allow global stats to update and ensure that no last-minute installs happened). Assuming no last-minute installs happen over those 24 hours, you can contact Google Play Developer Support and check to see if they can delete it.

Please note that their requirement for 0 installs is a hard requirement. No exceptions can be made (not even if you installed the app yourself for testing purposes).

You should use IS NOT NULL. (The comparison operators = and <> both give UNKNOWN with NULL on either side of the expression.)

SELECT * 
FROM table 
WHERE YourColumn IS NOT NULL;

Just for completeness I'll mention that in MySQL you can also negate the null safe equality operator but this is not standard SQL.

SELECT *
FROM table 
WHERE NOT (YourColumn <=> NULL);

Edited to reflect comments. It sounds like your table may not be in first normal form in which case changing the structure may make your task easier. A couple of other ways of doing it though...

SELECT val1 AS val
FROM  your_table
WHERE val1 IS NOT NULL
UNION ALL
SELECT val2 
FROM  your_table
WHERE val2 IS NOT NULL
/*And so on for all your columns*/

The disadvantage of the above is that it scans the table multiple times once for each column. That may possibly be avoided by the below but I haven't tested this in MySQL.

SELECT CASE idx
         WHEN 1 THEN val1
         WHEN 2 THEN val2
       END AS val
FROM   your_table
        /*CROSS JOIN*/
       JOIN (SELECT 1 AS idx
                   UNION ALL
                   SELECT 2) t
HAVING val IS NOT NULL  /*Can reference alias in Having in MySQL*/

Doesn't all of this assume that the base class is a new-style class?

class A:
    def __init__(self):
        print("A.__init__()")

class B(A):
    def __init__(self):
        print("B.__init__()")
        super(B, self).__init__()

Will not work in Python 2. class A must be new-style, i.e: class A(object)

The download from java.com which installs in /Library/Internet Plug-Ins is only the JRE, for development you probably want to download the JDK from http://www.oracle.com/technetwork/java/javase/downloads/index.html and install that instead. This will install the JDK at /Library/Java/JavaVirtualMachines/jdk1.7.0_<something>.jdk/Contents/Home which you can then add to Eclipse via Preferences -> Java -> Installed JREs.

import time
mintt=input("How many seconds you want to time?:")
timer=int(mintt)
while (timer != 0 ):
    timer=timer-1
    time.sleep(1)
    print(timer)

This work very good to time seconds.

If you mean using a literal, you simply have to create a binary string:

insert into Files (FileId, FileData) values (1, 0x010203040506)

And you will have a record with a six byte value for the FileData field.

You indicate in the comments that you want to just specify the file name, which you can't do with SQL Server 2000 (or any other version that I am aware of).

You would need a CLR stored procedure to do this in SQL Server 2005/2008 or an extended stored procedure (but I'd avoid that at all costs unless you have to) which takes the filename and then inserts the data (or returns the byte string, but that can possibly be quite long).

In regards to the question of only being able to get data from a SP/query, I would say the answer is yes, because if you give SQL Server the ability to read files from the file system, what do you do when you aren't connected through Windows Authentication, what user is used to determine the rights? If you are running the service as an admin (God forbid) then you can have an elevation of rights which shouldn't be allowed.

Maybe the following is what you are looking for:

SELECT name, pathfilename
  FROM table1
  NATURAL JOIN table2
  NATURAL JOIN table3
  WHERE name = 'John';

In my case in the module's build.gradle the mainClassName assignment must state the fully qualified class name, ie. as specified as the package name in the main class' source code file.

You can see a complete example using java 8, recursion and streams -> Dijkstra algorithm with java

Number of a columns in the result set you can get with code (as DB is used PostgreSQL):

//load the driver for PostgreSQL
Class.forName("org.postgresql.Driver");

String url = "jdbc:postgresql://localhost/test";
Properties props = new Properties();
props.setProperty("user","mydbuser");
props.setProperty("password","mydbpass");
Connection conn = DriverManager.getConnection(url, props);

//create statement
Statement stat = conn.createStatement();

//obtain a result set
ResultSet rs = stat.executeQuery("SELECT c1, c2, c3, c4, c5 FROM MY_TABLE");

//from result set give metadata
ResultSetMetaData rsmd = rs.getMetaData();

//columns count from metadata object
int numOfCols = rsmd.getColumnCount();

But you can get more meta-informations about columns:

for(int i = 1; i <= numOfCols; i++)
{
    System.out.println(rsmd.getColumnName(i));
}

And at least but not least, you can get some info not just about table but about DB too, how to do it you can find here and here.

I've had good results with FileServlet, as it supports pretty much all of HTTP (etags, chunking, etc.).

most editors support save as ‘Unicode’ encoding actually.

This is an unfortunate misnaming perpetrated by Windows.

Because Windows uses UTF-16LE encoding internally as the memory storage format for Unicode strings, it considers this to be the natural encoding of Unicode text. In the Windows world, there are ANSI strings (the system codepage on the current machine, subject to total unportability) and there are Unicode strings (stored internally as UTF-16LE).

This was all devised in the early days of Unicode, before we realised that UCS-2 wasn't enough, and before UTF-8 was invented. This is why Windows's support for UTF-8 is all-round poor.

This misguided naming scheme became part of the user interface. A text editor that uses Windows's encoding support to provide a range of encodings will automatically and inappropriately describe UTF-16LE as “Unicode”, and UTF-16BE, if provided, as “Unicode big-endian”.

(Other editors that do encodings themselves, like Notepad++, don't have this problem.)

If it makes you feel any better about it, ‘ANSI’ strings aren't based on any ANSI standard, either.

To represent the character you can use Universal Character Names (UCNs). The character '?' has the Unicode value U+0444 and so in C++ you could write it '\u0444' or '\U00000444'. Also if the source code encoding supports this character then you can just write it literally in your source code.

// both of these assume that the character can be represented with
// a single char in the execution encoding
char b = '\u0444';
char a = '?'; // this line additionally assumes that the source character encoding supports this character

Printing such characters out depends on what you're printing to. If you're printing to a Unix terminal emulator, the terminal emulator is using an encoding that supports this character, and that encoding matches the compiler's execution encoding, then you can do the following:

#include <iostream>

int main() {
    std::cout << "Hello, ? or \u0444!\n";
}

This program does not require that '?' can be represented in a single char. On OS X and most any modern Linux install this will work just fine, because the source, execution, and console encodings will all be UTF-8 (which supports all Unicode characters).

Things are harder with Windows and there are different possibilities with different tradeoffs.

Probably the best, if you don't need portable code (you'll be using wchar_t, which should really be avoided on every other platform), is to set the mode of the output file handle to take only UTF-16 data.

#include <iostream>
#include <io.h>
#include <fcntl.h>

int main() {
    _setmode(_fileno(stdout), _O_U16TEXT);
    std::wcout << L"Hello, \u0444!\n";
}

Portable code is more difficult.

Ram Narasimhan explained the concept very nicely here below is an alternative explanation through the code example of Naive Bayes in action
It uses an example problem from this book on page 351
This is the data set that we will be using

In the above dataset if we give the hypothesis = {"Age":'<=30', "Income":"medium", "Student":'yes' , "Creadit_Rating":'fair'} then what is the probability that he will buy or will not buy a computer.
The code below exactly answers that question.
Just create a file called named new_dataset.csv and paste the following content.

Age,Income,Student,Creadit_Rating,Buys_Computer
<=30,high,no,fair,no
<=30,high,no,excellent,no
31-40,high,no,fair,yes
>40,medium,no,fair,yes
>40,low,yes,fair,yes
>40,low,yes,excellent,no
31-40,low,yes,excellent,yes
<=30,medium,no,fair,no
<=30,low,yes,fair,yes
>40,medium,yes,fair,yes
<=30,medium,yes,excellent,yes
31-40,medium,no,excellent,yes
31-40,high,yes,fair,yes

This did not require any TechNet rigamarole or the use of their horrible Java 7 based download manager.

Alex, it's pretty much what your computer does when it boots up. ('Booting' a computer actually comes from the word bootstrapping)

Initially, the small program in your BIOS runs. That contains enough machine code to load and run a larger, more complex program.

That second program is probably something like NTLDR (in Windows) or LILO (in Linux), which then executes and is able to load, then run, the rest of the operating system.

Hi You can write data to bytes and then create a file in sdcard folder with whatever name and extension you want and then write the bytes to that file. This will save bitmap to sdcard.

ByteArrayOutputStream bytes = new ByteArrayOutputStream();
_bitmapScaled.compress(Bitmap.CompressFormat.JPEG, 40, bytes);

//you can create a new file name "test.jpg" in sdcard folder.
File f = new File(Environment.getExternalStorageDirectory()
                        + File.separator + "test.jpg");
f.createNewFile();
//write the bytes in file
FileOutputStream fo = new FileOutputStream(f);
fo.write(bytes.toByteArray());

// remember close de FileOutput
fo.close();

calling a function is simple ..

 myFunction();

so your code will be something like..

 $(function(){
     $('#elementID').click(function(){
         myFuntion();  //this will call your function
    });
 });

  $(function(){
     $('#elementID').click( myFuntion );

 });

or with some condition

if(something){
   myFunction();  //this will call your function
}

Here's how you can mock your FileConnection

Mock<IFileConnection> fileConnection = new Mock<IFileConnection>(
                                                           MockBehavior.Strict);
fileConnection.Setup(item => item.Get(It.IsAny<string>,It.IsAny<string>))
              .Throws(new IOException());

Then instantiate your Transfer class and use the mock in your method call

Transfer transfer = new Transfer();
transfer.GetFile(fileConnection.Object, someRemoteFilename, someLocalFileName);

Update:

First of all you have to mock your dependencies only, not the class you are testing(Transfer class in this case). Stating those dependencies in your constructor make it easy to see what services your class needs to work. It also makes it possible to replace them with fakes when you are writing your unit tests. At the moment it's impossible to replace those properties with fakes.

Since you are setting those properties using another dependency, I would write it like this:

public class Transfer
{
    public Transfer(IInternalConfig internalConfig)
    {
        source = internalConfig.GetFileConnection("source");
        destination = internalConfig.GetFileConnection("destination");
    }

    //you should consider making these private or protected fields
    public virtual IFileConnection source { get; set; }
    public virtual IFileConnection destination { get; set; }

    public virtual void GetFile(IFileConnection connection, 
        string remoteFilename, string localFilename)
    {
        connection.Get(remoteFilename, localFilename);
    }

    public virtual void PutFile(IFileConnection connection, 
        string localFilename, string remoteFilename)
    {
        connection.Get(remoteFilename, localFilename);
    }

    public virtual void TransferFiles(string sourceName, string destName)
    {
        var tempName = Path.GetTempFileName();
        GetFile(source, sourceName, tempName);
        PutFile(destination, tempName, destName);
    }
}

This way you can mock internalConfig and make it return IFileConnection mocks that does what you want.

Justin has correctly shown the expansion in the case where the join is just followed by a select. If you've got something else, it becomes more tricky due to transparent identifiers - the mechanism the C# compiler uses to propagate the scope of both halves of the join.

So to change Justin's example slightly:

var result = from sc in enumerableOfSomeClass
             join soc in enumerableOfSomeOtherClass
             on sc.Property1 equals soc.Property2
             where sc.X + sc.Y == 10
             select new { SomeClass = sc, SomeOtherClass = soc }

would be converted into something like this:

var result = enumerableOfSomeClass
    .Join(enumerableOfSomeOtherClass,
          sc => sc.Property1,
          soc => soc.Property2,
          (sc, soc) => new { sc, soc })
    .Where(z => z.sc.X + z.sc.Y == 10)
    .Select(z => new { SomeClass = z.sc, SomeOtherClass = z.soc });

The z here is the transparent identifier - but because it's transparent, you can't see it in the original query :)

The example you are using is wrong. See the man page for easy_setopt. In the example write_data uses its own FILE, *outfile, and not the fp that was specified in CURLOPT_WRITEDATA. That's why closing fp causes problems - it's not even opened.

This is more or less what it should look like (no libcurl available here to test)

#include <stdio.h>
#include <curl/curl.h>
/* For older cURL versions you will also need 
#include <curl/types.h>
#include <curl/easy.h>
*/
#include <string>

size_t write_data(void *ptr, size_t size, size_t nmemb, FILE *stream) {
    size_t written = fwrite(ptr, size, nmemb, stream);
    return written;
}

int main(void) {
    CURL *curl;
    FILE *fp;
    CURLcode res;
    char *url = "http://localhost/aaa.txt";
    char outfilename[FILENAME_MAX] = "C:\\bbb.txt";
    curl = curl_easy_init();
    if (curl) {
        fp = fopen(outfilename,"wb");
        curl_easy_setopt(curl, CURLOPT_URL, url);
        curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, write_data);
        curl_easy_setopt(curl, CURLOPT_WRITEDATA, fp);
        res = curl_easy_perform(curl);
        /* always cleanup */
        curl_easy_cleanup(curl);
        fclose(fp);
    }
    return 0;
}

Updated: as suggested by @rsethc types.h and easy.h aren't present in current cURL versions anymore.

The && function is not vectorized. You need the & function:

EUR <- PCs[which(PCs$V13 < 9 & PCs$V13 > 3), ]

I had a similar situation and solved by using a temp table inside the procedure, with the same fields being returned by the original Stored Procedure:

CREATE PROCEDURE mynewstoredprocedure
AS 
BEGIN

INSERT INTO temptable (field1, field2)
EXEC mystoredprocedure @param1, @param2

select field1, field2 from temptable

In addition to previous post you can have

<h:form rendered="#{bean.textvalue == 'value'}" />

Jsf 2.0

This worked for me

1. Save the file https://requirejs.org/docs/release/2.3.5/minified/require.js. It is the file for RequestJS which is what we will use.
2. Load it into your HTML content like this: <script data-main="your-script.js" src="require.js"></script>
   

Notes!

Use require(['moudle-name']) in your-script.js, not require('moudle-name')

Use const {ipcRenderer} = require(['electron']), not const {ipcRenderer} = require('electron')

Enums are not actual classes, even if they look like it. Internally, they are treated just like their underlying type (by default Int32). Therefore, you can only do this by "copying" single values from one enum to another and casting them to their integer number to compare them for equality.

The best way to go about this is to use 'BatchMode' in addition to 'StrictHostKeyChecking'. This way, your script will accept a new hostname and write it to the known_hosts file, but won't require yes/no intervention.

ssh -o BatchMode=yes -o StrictHostKeyChecking=no [email protected] "uptime"

The solution suggested

<system.webServer>
  <modules runAllManagedModulesForAllRequests="true" >
    <remove name="UrlRoutingModule"/>    
  </modules>
</system.webServer>

works, but can degrade performance and can even cause errors, because now all registered HTTP modules run on every request, not just managed requests (e.g. .aspx). This means modules will run on every .jpg .gif .css .html .pdf etc.

A more sensible solution is to include this in your web.config:

<system.webServer>
  <modules>
    <remove name="UrlRoutingModule-4.0" />
    <add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" preCondition="" />
  </modules>
</system.webServer>

Programs that prompt for passwords usually set the tty into "raw" mode, and read input directly from the tty. If you spawn the subprocess in a pty you can make that work. That is what Expect does...

you can also use MEDIUMBLOB/LONGBLOB or MEDIUMTEXT/LONGTEXT

A BLOB type in MySQL can store up to 65,534 bytes, if you try to store more than this much data MySQL will truncate the data. MEDIUMBLOB can store up to 16,777,213 bytes, and LONGBLOB can store up to 4,294,967,292 bytes.

Hope my answer is getting seen down here as this took me a while to figure out but I just got it working.

First of all you need to build and run the App on your simulator. Then you open the Activity Monitor. Double click the name of your App to find its content.

In the next screen open the Open Files and Ports tab and find the line with MyAppName.app/MyAppName.

Copy the link but make sure to stop at the MyAppName.app. Do not copy the path following it.

Control click onto the finder icon and select Go to folder.

]

Paste the path and click enter. You will see your MyAppName.app file. Copy it to the Desktop and zip it. Move it to your desired 2nd computer and unzip the file. Build a random project to have a simulator open.

Lastly: Literally drag and drop the App from your Desktop into your Simulator. You will see the install and the App opens and does not crash.

For parseInt to work, your string should have only numerical data. Something like this:

 str1 = "123.00";
 str2 = "50.00";
 total = parseInt(str1)+parseInt(str2);
 alert(total);

Can you split the string before you start processing them for a total?

What about doing some preprocessing? I would stitch a mark or id number in every sock in a way that every pair has the same mark/id number. This process might be done every time you buy a new pair of socks. Then, you could do a radix sort to get O(n) total cost. Find a place for every mark/id number and just pick all the socks one by one and put them into the correct place.

Those are two different approaches:

Imperative Management

kubectl create is what we call Imperative Management. On this approach you tell the Kubernetes API what you want to create, replace or delete, not how you want your K8s cluster world to look like.

Declarative Management

kubectl apply is part of the Declarative Management approach, where changes that you may have applied to a live object (i.e. through scale) are "maintained" even if you apply other changes to the object.

You can read more about imperative and declarative management in the Kubernetes Object Management documentation.

Just a quick suggestion.. As indexing costs you additional writes and storage space, so if your application requires more insert/update operation, you might want to use tables without indexes, but if it requires more data retrieval operations, you should go for indexed table.

If you're planning to generate a single JAR file with all of its dependencies (the typical xxxx-all.jar), then provided scope matters, because the classes inside this scope won't be package in the resulting JAR.

See maven-assembly-plugin for more information

When I was trying to accomplish something very similar, I ended up doing something along these lines:

wp-content/themes/resources/functions.php

add_action('init', 'my_php_function');
function my_php_function() {
    if (stripos($_SERVER['REQUEST_URI'], 'page-with-custom-php') !== false) {
        // add desired php code here
    }
}

I'm unable to find an scenario where a global var is the best option, of course you can have one, but take a look at these examples and you may find a better way to accomplish the same:

Scenario 1: Put the stuff in config files

You need some value that it's the same across the application, but it changes depending on the environment (production, dev or test), the mailer type as example, you'd need:

// File: config/environments/production.json
{
    "mailerType": "SMTP",
    "mailerConfig": {
      "service": "Gmail",
      ....
}

and

// File: config/environments/test.json
{
    "mailerType": "Stub",
    "mailerConfig": {
      "error": false
    }
}

(make a similar config for dev too)

To decide which config will be loaded make a main config file (this will be used all over the application)

// File: config/config.js
var _ = require('underscore');

module.exports = _.extend(
    require(__dirname + '/../config/environments/' + process.env.NODE_ENV + '.json') || {});

And now you can get the data like this:

// File: server.js
...
var config = require('./config/config');
...
mailer.setTransport(nodemailer.createTransport(config.mailerType, config.mailerConfig));

Scenario 2: Use a constants file

// File: constants.js
module.exports = {
  appName: 'My neat app',
  currentAPIVersion: 3
};

And use it this way

// File: config/routes.js

var constants = require('../constants');

module.exports = function(app, passport, auth) {
  var apiroot = '/api/v' + constants.currentAPIVersion;
...
  app.post(apiroot + '/users', users.create);
...

Scenario 3: Use a helper function to get/set the data

Not a big fan of this one, but at least you can track the use of the 'name' (citing the OP's example) and put validations in place.

// File: helpers/nameHelper.js

var _name = 'I shall not be null'

exports.getName = function() {
  return _name;
};

exports.setName = function(name) {
  //validate the name...
  _name = name;
};

And use it

// File: controllers/users.js

var nameHelper = require('../helpers/nameHelper.js');

exports.create = function(req, res, next) {
  var user = new User();
  user.name = req.body.name || nameHelper.getName();
  ...

There could be a use case when there is no other solution than having a global var, but usually you can share the data in your app using one of these scenarios, if you are starting to use node.js (as I was sometime ago) try to organize the way you handle the data over there because it can get messy really quick.

sizeof(source) returns the number of bytes required by the pointer char*. You should replace it with strlen(source) which will be the length of the string you're trying to display.

Also, you should probably replace printf("%s",source[i]) with printf("%c",source[i]) since you're displaying a character.

On the other hand, referring to a different blogging Scott (Watermasyck, of Telligent) - they found that most users could speed up the websites (using Telligent's Community Server), by putting the database on the same machine as the web site. However, in their customer's case, usually the db & web server are the only applications on that machine, and the website isn't straining the machine that much. Then, the efficiency of not having to send data across the network more that made up for the increased strain.

in the example below I exclude

spring-boot-starter-tomcat

compile("org.springframework.boot:spring-boot-starter-web") {
     //by both name and group
     exclude group: 'org.springframework.boot', module: 'spring-boot-starter-tomcat' 
}

For this, you need to declare the variable as global. However, a global variable is also accessible from outside the module by using module_name.var_name. Add this as the first line of your module:

global __DBNAME__

You can do that with

var list = new List<string>{ "foo", "bar" };

Here are some other common instantiations of other common Data Structures:

Dictionary

var dictionary = new Dictionary<string, string> 
{
    { "texas",   "TX" },
    { "utah",    "UT" },
    { "florida", "FL" }
};

Array list

var array = new string[] { "foo", "bar" };

Queue

var queque = new Queue<int>(new[] { 1, 2, 3 });

Stack

var queque = new Stack<int>(new[] { 1, 2, 3 });

As you can see for the majority of cases it is merely adding the values in curly braces, or instantiating a new array followed by curly braces and values.

For those getting this error in a Jenkins pipeline, it can be fixed by using an SSH Agent plugin. Then wrap your git commands in something like this:

sshagent(['my-ssh-key']) {
    git remote set-url origin [email protected]:username/reponame.git
    sh 'git push origin branch_name'
}

This happened to me because I had the 'copyright' symbol in one of my strings! Once it was removed, problem solved.

A good rule of thumb, make sure that characters not appearing on your keyboard are removed if you are seeing this error.

Just look in file /var/log/auth.log on the server. Setting additional verbosity with -vv on the client side won't help, because the server is unlikely to offer too much information to a possible attacker.

Tuples are available since .NET4.0 and support generics:

Tuple<string, int> t = new Tuple<string, int>("Hello", 4);

In previous versions you can use System.Collections.Generic.KeyValuePair<K, V> or a solution like the following:

public class Pair<T, U> {
    public Pair() {
    }

    public Pair(T first, U second) {
        this.First = first;
        this.Second = second;
    }

    public T First { get; set; }
    public U Second { get; set; }
};

And use it like this:

Pair<String, int> pair = new Pair<String, int>("test", 2);
Console.WriteLine(pair.First);
Console.WriteLine(pair.Second);

This outputs:

test
2

Or even this chained pairs:

Pair<Pair<String, int>, bool> pair = new Pair<Pair<String, int>, bool>();
pair.First = new Pair<String, int>();
pair.First.First = "test";
pair.First.Second = 12;
pair.Second = true;

Console.WriteLine(pair.First.First);
Console.WriteLine(pair.First.Second);
Console.WriteLine(pair.Second);

That outputs:

test
12
true

If your Manifest.xml has the default android:theme="@style/AppTheme"

Go to res/values/styles.xml and change

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

to

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

And the ActionBar is disappeared!

boto3 now has a nicer interface than the client:

resource = boto3.resource('s3')
my_bucket = resource.Bucket('MyBucket')
my_bucket.download_file(key, local_filename)

This by itself isn't tremendously better than the client in the accepted answer (although the docs say that it does a better job retrying uploads and downloads on failure) but considering that resources are generally more ergonomic (for example, the s3 bucket and object resources are nicer than the client methods) this does allow you to stay at the resource layer without having to drop down.

Resources generally can be created in the same way as clients, and they take all or most of the same arguments and just forward them to their internal clients.

I got a similar error but the root cause was different. After installing the mongodb using homebrew. https://docs.mongodb.com/manual/installation/ I have to start the "mongod" service before giving the "mongo" command on terminal.

You can use console.log(...) directly in Firefox but not in IEs. In IEs you have to use window.console.

For anyone trying to

• "show text under marker on google maps", or
• "Google Maps Marker Label With Multiple Characters"

...in 2019, it's worth noting some of the code referenced here no longer exists (officially). Google discontinued support for the "MarkerWithLabel" project a long time ago. It was originally hosted on Google code here, now it's unofficially hosted on Github here.

But there is another project Google maintained until 2016, called "MapLabel"s. That approach is different (and arguably better). You create a separate map label object with the same origin as the marker instead of adding a mapLabel option to the marker itself. You can make a marker with label with multiple characters using js-marker-label.

I think you'll understand this
if didn't then use vbscript to vb/C# converter.
still didn't then contact Me.

I have done this before ,can't find the code now that this why i'm not directly givin' you the code.

This is an old question, but here's another way to do it.

You can modify the R code itself instead of the chunk options, by wrapping the source call in suppressPackageStartupMessages(), suppressMessages(), and/or suppressWarnings(). E.g:

```{r echo=FALSE}
suppressWarnings(suppressMessages(suppressPackageStartupMessages({
source("C:/Rscripts/source.R")
})
```

You can also put those functions around your library() calls inside the "source.R" script.

When you see dtype('O') inside dataframe this means Pandas string.

What is dtype?

Something that belongs to pandas or numpy, or both, or something else? If we examine pandas code:

df = pd.DataFrame({'float': [1.0],
                    'int': [1],
                    'datetime': [pd.Timestamp('20180310')],
                    'string': ['foo']})
print(df)
print(df['float'].dtype,df['int'].dtype,df['datetime'].dtype,df['string'].dtype)
df['string'].dtype

It will output like this:

   float  int   datetime string    
0    1.0    1 2018-03-10    foo
---
float64 int64 datetime64[ns] object
---
dtype('O')

You can interpret the last as Pandas dtype('O') or Pandas object which is Python type string, and this corresponds to Numpy string_, or unicode_ types.

Pandas dtype    Python type     NumPy type          Usage
object          str             string_, unicode_   Text

Like Don Quixote is on ass, Pandas is on Numpy and Numpy understand the underlying architecture of your system and uses the class numpy.dtype for that.

Data type object is an instance of numpy.dtype class that understand the data type more precise including:

• Type of the data (integer, float, Python object, etc.)
• Size of the data (how many bytes is in e.g. the integer)
• Byte order of the data (little-endian or big-endian)
• If the data type is structured, an aggregate of other data types, (e.g., describing an array item consisting of an integer and a float)
• What are the names of the "fields" of the structure
• What is the data-type of each field
• Which part of the memory block each field takes
• If the data type is a sub-array, what is its shape and data type

In the context of this question dtype belongs to both pands and numpy and in particular dtype('O') means we expect the string.

Here is some code for testing with explanation: If we have the dataset as dictionary

import pandas as pd
import numpy as np
from pandas import Timestamp

data={'id': {0: 1, 1: 2, 2: 3, 3: 4, 4: 5}, 'date': {0: Timestamp('2018-12-12 00:00:00'), 1: Timestamp('2018-12-12 00:00:00'), 2: Timestamp('2018-12-12 00:00:00'), 3: Timestamp('2018-12-12 00:00:00'), 4: Timestamp('2018-12-12 00:00:00')}, 'role': {0: 'Support', 1: 'Marketing', 2: 'Business Development', 3: 'Sales', 4: 'Engineering'}, 'num': {0: 123, 1: 234, 2: 345, 3: 456, 4: 567}, 'fnum': {0: 3.14, 1: 2.14, 2: -0.14, 3: 41.3, 4: 3.14}}
df = pd.DataFrame.from_dict(data) #now we have a dataframe

print(df)
print(df.dtypes)

The last lines will examine the dataframe and note the output:

   id       date                  role  num   fnum
0   1 2018-12-12               Support  123   3.14
1   2 2018-12-12             Marketing  234   2.14
2   3 2018-12-12  Business Development  345  -0.14
3   4 2018-12-12                 Sales  456  41.30
4   5 2018-12-12           Engineering  567   3.14
id               int64
date    datetime64[ns]
role            object
num              int64
fnum           float64
dtype: object

All kind of different dtypes

df.iloc[1,:] = np.nan
df.iloc[2,:] = None

But if we try to set np.nan or None this will not affect the original column dtype. The output will be like this:

print(df)
print(df.dtypes)

    id       date         role    num   fnum
0  1.0 2018-12-12      Support  123.0   3.14
1  NaN        NaT          NaN    NaN    NaN
2  NaN        NaT         None    NaN    NaN
3  4.0 2018-12-12        Sales  456.0  41.30
4  5.0 2018-12-12  Engineering  567.0   3.14
id             float64
date    datetime64[ns]
role            object
num            float64
fnum           float64
dtype: object

So np.nan or None will not change the columns dtype, unless we set the all column rows to np.nan or None. In that case column will become float64 or object respectively.

You may try also setting single rows:

df.iloc[3,:] = 0 # will convert datetime to object only
df.iloc[4,:] = '' # will convert all columns to object

And to note here, if we set string inside a non string column it will become string or object dtype.

public void javascriptclick(String element)
    { 
        WebElement webElement=driver.findElement(By.xpath(element));
        JavascriptExecutor js = (JavascriptExecutor) driver;

        js.executeScript("arguments[0].click();",webElement);   
        System.out.println("javascriptclick"+" "+ element);

    }

use Object.keys:

Object.keys(this.formErrors).map(key => {
  this.formErrors[key] = '';
  const control = form.get(key);

  if(control && control.dirty && !control.valid) {
    const messages = this.validationMessages[key];
    Object.keys(control.errors).map(key2 => {
      this.formErrors[key] += messages[key2] + ' ';
    });
  }
});

Throwing out of a destructor can result in a crash, because this destructor might be called as part of "Stack unwinding". Stack unwinding is a procedure which takes place when an exception is thrown. In this procedure, all the objects that were pushed into the stack since the "try" and until the exception was thrown, will be terminated -> their destructors will be called. And during this procedure, another exception throw is not allowed, because it's not possible to handle two exceptions at a time, thus, this will provoke a call to abort(), the program will crash and the control will return to the OS.

Is there any advantage in creating a temporary file in a more careful way

The temporary files are usually created in the temporary directory (such as /tmp) where all other users and processes has read and write access (any other script can create the new files there). Therefore the script should be careful about creating the files such as using with the right permissions (e.g. read only for the owner, see: help umask) and filename should be be not easily guessed (ideally random). Otherwise if the filenames aren't unique, it can create conflict with the same script ran multiple times (e.g. race condition) or some attacker could either hijack some sensitive information (e.g. when permissions are too open and filename is easy to guess) or create/replacing the file with their own version of the code (like replacing the commands or SQL queries depending on what is being stored).

You could use the following approach to create the temporary directory:

TMPDIR=".${0##*/}-$$" && mkdir -v "$TMPDIR"

or temporary file:

TMPFILE=".${0##*/}-$$" && touch "$TMPFILE"

However it is still predictable and not considered safe.

As per man mktemp, we can read:

Traditionally, many shell scripts take the name of the program with the pid as a suffix and use that as a temporary file name. This kind of naming scheme is predictable and the race condition it creates is easy for an attacker to win.

So to be safe, it is recommended to use mktemp command to create unique temporary file or directory (-d).

No this is not enough (in some specific cases)! By default PDO uses emulated prepared statements when using MySQL as a database driver. You should always disable emulated prepared statements when using MySQL and PDO:

$dbh->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

Another thing that always should be done it set the correct encoding of the database:

$dbh = new PDO('mysql:dbname=dbtest;host=127.0.0.1;charset=utf8', 'user', 'pass');

Also see this related question: How can I prevent SQL injection in PHP?

Also note that that only is about the database side of the things you would still have to watch yourself when displaying the data. E.g. by using htmlspecialchars() again with the correct encoding and quoting style.

So, I would like to explain the scenario where I had to make use of this solution. Basically, I wanted to undo the background-color attribute set by another CSS. The expected end result was to make it look as though the original CSS had never applied the background-color attribute . Setting background-color:transparent; made that effective.

javac only compiles the code. You need to use java command to run the code. The error is because your classpath doesn't contain the class Subclass iwhen you tried to compile it. you need to add them with the -cp variable in javac command

java -cp classpath-entries mainjava arg1 arg2 should run your code with 2 arguments

Most of the above mentioned solution didn't worked for me. However, below given solution works just fine:

<div class="fixed-bottom">...</div>      

Source

You have to enable the features in Add/Remove Programs section of your Control Panel. Select "Turn Windows features on or off"

Use print_r($votes); to inspect the array $votes, you will see that key 0 does not exist there. It will return NULL and throw that error.

select this_.code from true.employee this_ where this_.code=? is what will be sent to your database.

this_ is an alias for that instance of the employee table.

Another way is to create functions in global scope. This was necessary for me since it wasn't possible in Angular 1.5 to reach a component's scope.

Example:

angular.module("app", []).component("component", {_x000D_
  controller: ["$window", function($window) {_x000D_
    var self = this;_x000D_
    _x000D_
    self.logg = function() {_x000D_
      console.log("logging!");_x000D_
    };_x000D_
    _x000D_
    $window.angularControllerLogg = self.logg;_x000D_
  }_x000D_
});_x000D_
               _x000D_
window.angularControllerLogg();

create a new java project in Eclipse and copy .java files to its src directory, if you don't know where those source files should be placed, right click on the root of the project and choose new->class to create a test class and see where its .java file is placed, then put other files with it, in the same directory, you may have to adjust the package in those source files according to the new project directory structure.

if you use external libraries in your code, you have two options: either copy / download jar files or use maven if you use maven you'll have to create the project at maven project in the first place, creating java projects as maven projects are the way to go anyway but that's for another post...

os.stat returns a named tuple with st_mtime and st_ctime attributes. The modification time is st_mtime on both platforms; unfortunately, on Windows, ctime means "creation time", whereas on POSIX it means "change time". I'm not aware of any way to get the creation time on POSIX platforms.

I used accepted answer reference and would like to put an example, since Angular 2 documentation is very very hard to read, I hope this is easier:

1. Import NgZone:

   import { Component, NgZone } from '@angular/core';
   

2. Add it to your class constructor

   constructor(public zone: NgZone, ...args){}
   

3. Run code with zone.run:

   this.zone.run(() => this.donations = donations)
   

According to the GCC manual for omp_get_num_threads:

In a sequential section of the program omp_get_num_threads returns 1

So this:

cout<<"sum="<<sum<<endl;
cout<<"threads="<<omp_get_num_threads()<<endl;

Should be changed to something like:

#pragma omp parallel
{
    cout<<"sum="<<sum<<endl;
    cout<<"threads="<<omp_get_num_threads()<<endl;
}

The code I use follows Hristo's advice of disabling dynamic teams, too.

Since I needed something, that also works with Localization, I came up with these two methods:

    private int getArrayPositionForValue(final int arrayResId, final String value) {
        final Resources english = Utils.getLocalizedResources(this, new Locale("en"));
        final List<String> arrayValues = Arrays.asList(english.getStringArray(arrayResId));

        for (int position = 0; position < arrayValues.size(); position++) {
            if (arrayValues.get(position).equalsIgnoreCase(value)) {
                return position;
            }
        }
        Log.w(TAG, "getArrayPosition() --> return 0 (fallback); No index found for value = " + value);
        return 0;
    }

As you can see, I also stumbled over additional complexity of case sensitivity between arrays.xml and the value I am comparing against. If you don't have this, the above method can be simplified to something like:

return arrayValues.indexOf(value);

Static helper method

public static Resources getLocalizedResources(Context context, Locale desiredLocale) {
        Configuration conf = context.getResources().getConfiguration();
        conf = new Configuration(conf);
        conf.setLocale(desiredLocale);
        Context localizedContext = context.createConfigurationContext(conf);
        return localizedContext.getResources();
    }

Just set your width to auto:

#myWorkContent{
    width: auto;
    height:210px;
    border: 13px solid #bed5cd;
    overflow-x: scroll;
    overflow-y: hidden;
    white-space: nowrap;
}

This way your div can be as wide as possible, so you can add as many kitty images as possible ;3

Your div's width will expand based on the child elements it contains.

I have the same problem trying to connect to an 3270 terminal using the s3270 scripting software in Python. Now I'm solving the problem with an subclass of Process that I found here:

http://code.activestate.com/recipes/440554/

And here is the sample taken from file:

def recv_some(p, t=.1, e=1, tr=5, stderr=0):
    if tr < 1:
        tr = 1
    x = time.time()+t
    y = []
    r = ''
    pr = p.recv
    if stderr:
        pr = p.recv_err
    while time.time() < x or r:
        r = pr()
        if r is None:
            if e:
                raise Exception(message)
            else:
                break
        elif r:
            y.append(r)
        else:
            time.sleep(max((x-time.time())/tr, 0))
    return ''.join(y)

def send_all(p, data):
    while len(data):
        sent = p.send(data)
        if sent is None:
            raise Exception(message)
        data = buffer(data, sent)

if __name__ == '__main__':
    if sys.platform == 'win32':
        shell, commands, tail = ('cmd', ('dir /w', 'echo HELLO WORLD'), '\r\n')
    else:
        shell, commands, tail = ('sh', ('ls', 'echo HELLO WORLD'), '\n')

    a = Popen(shell, stdin=PIPE, stdout=PIPE)
    print recv_some(a),
    for cmd in commands:
        send_all(a, cmd + tail)
        print recv_some(a),
    send_all(a, 'exit' + tail)
    print recv_some(a, e=0)
    a.wait()

Following the first logic, you have to use = in the comparison.

<?php 
    function age($birthdate) {
        $birthdate = strtotime($birthdate);
        $now = time();
        $age = 0;
        while ($now >= ($birthdate = strtotime("+1 YEAR", $birthdate))) {
            $age++;
        }
        return $age;
    }

    // Usage:

    echo age(implode("-",array_reverse(explode("/",'14/09/1986')))); // format yyyy-mm-dd is safe!
    echo age("-10 YEARS") // without = in the comparison, will returns 9.

?>

I think your solution would be the standard way, but - as you noted yourself - it is probably not the fastest way possible.

You may look at GNU Trove. That is a library which contains all sorts of fast primitive Collections. Your example would use a TObjectIntHashMap which has a method adjustOrPutValue which does exactly what you want.

not found on the java.library.path: /usr/java/packages/lib/amd64:/usr/lib64:/lib64:/lib:/usr/lib

The native lib is expected in one of the following locations

/usr/java/packages/lib/amd64
/usr/lib64
/lib64
/lib
/usr/lib

and not in

tomcat/lib

The files in tomcat/lib are all jar file and are added by tomcat to the classpath so that they are available to your application.

The native lib is needed by tomcat to perform better on the platform it is installed on and thus cannot be a jar, for linux it could be a .so file, for windows it could be a .dll file.

Just download the native library for your platform and place it in the one of the locations tomcat is expecting it to be.

Note that you are not required to have this lib for development/test purposes. Tomcat runs just fine without it.

org.apache.catalina.startup.Catalina start INFO: Server startup in 2882 ms

EDIT

The output you are getting is very normal, it's just some logging outputs from tomcat, the line right above indicates that the server correctly started and is ready for operating.

If you are troubling with running your servlet then after the run on sever command eclipse opens a browser window (embeded (default) or external, depends on your config). If nothing shows on the browser, then check the url bar of the browser to see whether your servlet was requested or not.

It should be something like that

http://localhost:8080/<your-context-name>/<your-servlet-name>

EDIT 2

Try to call your servlet using the following url

http://localhost:8080/com.filecounter/FileCounter

Also each web project has a web.xml, you can find it in your project under WebContent\WEB-INF.

It is better to configure your servlets there using servlet-name servlet-class and url-mapping. It could look like that:

  <servlet>
    <description></description>
    <display-name>File counter - My first servlet</display-name>
    <servlet-name>file_counter</servlet-name>
    <servlet-class>com.filecounter.FileCounter</servlet-class>
  </servlet>

  <servlet-mapping>
    <servlet-name>file_counter</servlet-name>
    <url-pattern>/FileFounter</url-pattern>
  </servlet-mapping>

In eclipse dynamic web project the default context name is the same as your project name.

http://localhost:8080/<your-context-name>/FileCounter

will work too.

This was a very important issue for me in order for my site to be multilingual. So here is my conclusion tested in Firefox and Chrome.

jQuery trigger comes in handy.

So this hides the standard boring type=file labels. You can place any label you want and format anyway. I customized a script from http://demo.smarttutorials.net/ajax1/. The script allows multiple file uploads with thumbnail preview and uses PHP and MySQL.

<form enctype="multipart/form-data" name='imageform' role="form"    ="imageform" method="post" action="upload_ajax.php">
    <div class="form-group">
        <div id="select_file">Select a file</div>
        <input class='file' type="file" style="display: none " class="form-control" name="images_up" id="images_up" placeholder="Please choose your image">
        <div id="my_file"></div>
        <span class="help-block"></span>
    </div>
    <div id="loader" style="display: none;">
        Please wait image uploading to server....
    </div>
    <input type="submit" value="Upload" name="image_upload" id="image_upload" class="btn"/>
</form>

$('#select_file').click(function() {
    $('#images_up').trigger('click');
    $('#images_up').change(function() {
        var filename = $('#images_up').val();
        if (filename.substring(3,11) == 'fakepath') {
            filename = filename.substring(12);
        } // Remove c:\fake at beginning from localhost chrome
        $('#my_file').html(filename);
   });
});

You could try:

const obj = { a: 4, b: 0.5 , c: 0.35, d: 5 };
const max = Math.max.apply(null, Object.values(obj));
console.log(max) // 5

Following code will:

• print enabled protocols
• print available protocols
• enable TLS1.2 if platform supports it and if it is not enabled to begin with
• disable SSL3 if it is enabled
• print end result

Constants:

• 48 is SSL3
• 192 is TLS1
• 768 is TLS1.1
• 3072 is TLS1.2

Other protocols will not be affected. This makes this compatible with future protocols (Tls1.3, etc).

Code

// print initial status
    Console.WriteLine("Runtime: " + System.Diagnostics.FileVersionInfo.GetVersionInfo(typeof(int).Assembly.Location).ProductVersion);
    Console.WriteLine("Enabled protocols:   " + ServicePointManager.SecurityProtocol);
    Console.WriteLine("Available protocols: ");
    Boolean platformSupportsTls12 = false;
    foreach (SecurityProtocolType protocol in Enum.GetValues(typeof(SecurityProtocolType))) {                
        Console.WriteLine(protocol.GetHashCode());
        if (protocol.GetHashCode() == 3072){
            platformSupportsTls12 = true;
        }
    }
    Console.WriteLine("Is Tls12 enabled: " + ServicePointManager.SecurityProtocol.HasFlag((SecurityProtocolType)3072));    


// enable Tls12, if possible
    if (!ServicePointManager.SecurityProtocol.HasFlag((SecurityProtocolType)3072)){
        if (platformSupportsTls12){
            Console.WriteLine("Platform supports Tls12, but it is not enabled. Enabling it now.");
            ServicePointManager.SecurityProtocol |= (SecurityProtocolType)3072;
        } else {
            Console.WriteLine("Platform does not supports Tls12.");
        }
    }

// disable ssl3
   if (ServicePointManager.SecurityProtocol.HasFlag(SecurityProtocolType.Ssl3)) { 
      Console.WriteLine("Ssl3SSL3 is enabled. Disabling it now.");
      // disable SSL3. Has no negative impact if SSL3 is already disabled. The enclosing "if" if just for illustration.
      System.Net.ServicePointManager.SecurityProtocol &= ~SecurityProtocolType.Ssl3;                      
   }
    Console.WriteLine("Enabled protocols:   " + ServicePointManager.SecurityProtocol);

Output

Runtime: 4.7.2114.0
Enabled protocols:   Ssl3, Tls
Available protocols: 
0
48
192
768
3072
Is Tls12 enabled: False
Platform supports Tls12, but it is not enabled. Enabling it now.
Ssl3 is enabled. Disabling it now.
Enabled protocols:   Tls, Tls12

You need to delete your old db folder and recreate new one. It will resolve your issue.

ex: url/:id

var sample= app.controller('sample', function ($scope, $routeParams) {
  $scope.init = function () {
    var qa_id = $routeParams.qa_id;
  }
});

This can be accomplished with a simple VBA function. Excel has support for a Worksheet Change Sub which can be programmed to put a date in a related column every time it fires.

Private Sub Worksheet_Change(ByVal Target As Range)
    If Target.Column = 2 And Target.Offset(0, 3).Value = "" Then
        Target.Offset(0, 3) = Format(Now(), "HH:MM:SS")
    End If
End Sub

A quick explanation. The following "if" statement checks for two things: (1) if it is the second column that changed (Column B), and (2) if the cell 3 columns over (Column E) is currently empty.

If Target.Column = 2 And Target.Offset(0, 3).Value = "" Then

If both conditions are true, then it puts the date into the cell in Column E with the NOW() function.

Target.Offset(0, 3) = Format(Now(), "HH:MM:SS")

Range.Offset

Range.Column

You could use the following code, it does a recursive call into the function in order to properly wait for the desired time.

function exportar(page,miliseconds,totalpages)
{
    if (page <= totalpages)
    {
        nextpage = page + 1;
        console.log('fnExcelReport('+ page +'); nextpage = '+ nextpage + '; miliseconds = '+ miliseconds + '; totalpages = '+ totalpages );
        fnExcelReport(page);
        setTimeout(function(){
            exportar(nextpage,miliseconds,totalpages);
        },miliseconds);
    };
}

Browsers control a lot of this functionality but

<a href="http://www.yahoo.com" target="_blank">Go to Yahoo</a>

will attempt to open yahoo.com in a new window.

For chromium browser is so simple.

Version : navigator.userAgentData.brands[0].version

Browser Name : navigator.userAgentData.brands[0].brand

There is a method called unbindService that will take a ServiceConnection which you will have created upon calling bindService. This will allow you to disconnect from the service while still leaving it running.

This may pose a problem when you connect to it again, since you probably don't know whether it's running or not when you start the activity again, so you'll have to consider that in your activity code.

Good luck!

var array = string.split(',')

and good morning, too, since I have to type 30 chars ...

One thing to note that you guys are over-complicating the problem just like a lot of other posts! All you need to do is create drawable selectors with whatever backgrounds you need and set them to actual items. I just spend two hours trying your solutions (all suggested on this page) and none of them worked. Not to mention that there are tons of errors that essentially slow your performance in those try/catch blocks you have.

Anyways here is a menu xml file:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/m1"
          android:icon="@drawable/item1_selector"
          />
    <item android:id="@+id/m2"
          android:icon="@drawable/item2_selector"
          />
</menu>

Now in your item1_selector:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@drawable/item_highlighted" />
    <item android:state_selected="true" android:drawable="@drawable/item_highlighted" />
    <item android:state_focused="true" android:drawable="@drawable/item_nonhighlighted" />
    <item android:drawable="@drawable/item_nonhighlighted" />
</selector>

Next time you decide to go to the supermarket through Canada try google maps!

If you're running python3, you'll have to do:

pip3 install lxml

Set a session variable for every page on your site (actual pages not includes or rpcs) that contains the current page name, then in your Ajax call pass a nonce salted with the $_SERVER['SCRIPT_NAME'];

<?php
function create_nonce($optional_salt='')
{
    return hash_hmac('sha256', session_id().$optional_salt, date("YmdG").'someSalt'.$_SERVER['REMOTE_ADDR']);
}
$_SESSION['current_page'] = $_SERVER['SCRIPT_NAME'];
?>

<form>
  <input name="formNonce" id="formNonce" type="hidden" value="<?=create_nonce($_SERVER['SCRIPT_NAME']);?>">
  <label class="form-group">
    Login<br />
    <input name="userName" id="userName" type="text" />
  </label>
  <label class="form-group">
    Password<br />
    <input name="userPassword" id="userPassword" type="password" />
  </label>
  <button type="button" class="btnLogin">Sign in</button>
</form>
<script type="text/javascript">
    $("form.login button").on("click", function() {
        authorize($("#userName").val(),$("#userPassword").val(),$("#formNonce").val());
    });

    function authorize (authUser, authPassword, authNonce) {
        $.ajax({
          type: "POST",
          url: "/inc/rpc.php",
          dataType: "json",
          data: "userID="+authUser+"&password="+authPassword+"&nonce="+authNonce
        })
        .success(function( msg ) {
            //some successful stuff
        });
    }
</script>

Then in the rpc you are calling test the nonce you passed, if it is good then odds are pretty great that your rpc was legitimately called:

<?php
function check_nonce($nonce, $optional_salt='')
{
    $lasthour = date("G")-1<0 ? date('Ymd').'23' : date("YmdG")-1;
    if (hash_hmac('sha256', session_id().$optional_salt, date("YmdG").'someSalt'.$_SERVER['REMOTE_ADDR']) == $nonce || 
        hash_hmac('sha256', session_id().$optional_salt, $lasthour.'someSalt'.$_SERVER['REMOTE_ADDR']) == $nonce)
    {
        return true;
    } else {
        return false;
    }
}

$ret = array();
header('Content-Type: application/json');
if (check_nonce($_POST['nonce'], $_SESSION['current_page']))
{
    $ret['nonce_check'] = 'passed';
} else {
    $ret['nonce_check'] = 'failed';
}
echo json_encode($ret);
exit;
?>

edit: FYI the way I have it set the nonce is only good for an hour and change, so if they have not refreshed the page doing the ajax call in the last hour or 2 the ajax request will fail.

Path.GetDirectoryName()... but you need to know that the path you are passing to it does contain a file name; it simply removes the final bit from the path, whether it is a file name or directory name (it actually has no idea which).

You could validate first by testing File.Exists() and/or Directory.Exists() on your path first to see if you need to call Path.GetDirectoryName

\n - simple newline character insertion works:

# Here's the test example - string with newline char:
In [36]: test_line = "Hi!!!\n testing first line.. \n testing second line.. \n and third line....."

# Output:
In [37]: print(test_line)

Hi!!!
 testing first line..
 testing second line..
 and third line.....

if (args[i] == "&")

Ok, let's disect what this does.

args is an array of pointers. So, here you are comparing args[i] (a pointer) to "&" (also a pointer). Well, the only way this will every be true is if somewhere you have args[i]="&" and even then, "&" is not guaranteed to point to the same place everywhere.

I believe what you are actually looking for is either strcmp to compare the entire string or your wanting to do if (*args[i] == '&') to compare the first character of the args[i] string to the & character

GO ends a batch, you would only very rarely need to use it in code. Be aware that if you use it in a stored proc, no code after the GO will be executed when you execute the proc.

BEGIN and END are needed for any procedural type statements with multipe lines of code to process. You will need them for WHILE loops and cursors (which you will avoid if at all possible of course) and IF statements (well techincally you don't need them for an IF statment that only has one line of code, but it is easier to maintain the code if you always put them in after an IF). CASE statements also use an END but do not have a BEGIN.

...building on Jan-Philip Gehrcke's answer.

The reason why len(df) or len(df.index) is faster than df.shape[0]:

Look at the code. df.shape is a @property that runs a DataFrame method calling len twice.

df.shape??
Type:        property
String form: <property object at 0x1127b33c0>
Source:
# df.shape.fget
@property
def shape(self):
    """
    Return a tuple representing the dimensionality of the DataFrame.
    """
    return len(self.index), len(self.columns)

And beneath the hood of len(df)

df.__len__??
Signature: df.__len__()
Source:
    def __len__(self):
        """Returns length of info axis, but here we use the index """
        return len(self.index)
File:      ~/miniconda2/lib/python2.7/site-packages/pandas/core/frame.py
Type:      instancemethod

len(df.index) will be slightly faster than len(df) since it has one less function call, but this is always faster than df.shape[0]

I don't think it's good to generally turn off CSRF protection as long as you don't exclusively implement an API.

When looking at the Rails 4 API documentation for ActionController I found that you can turn off forgery protection on a per controller or per method base.

For example to turn off CSRF protection for methods you can use

class FooController < ApplicationController
  protect_from_forgery except: :index

In my case it happened after I moved my solution folder from one location to another, re-organized it a bit and in the process its relative folder structure changed.

So I had to edit all entries similar to the following one in my .csproj file from

  <Import Project="..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets" Condition="Exists('..\packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets')" />

to

  <Import Project="packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets" Condition="Exists('packages\Microsoft.Bcl.Build.1.0.14\tools\Microsoft.Bcl.Build.targets')" />

(Note the change from ..\packages\ to packages\. It might be a different relative structure in your case, but you get the idea.)

Compose an email in the phone email client:

Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("plain/text");
intent.putExtra(Intent.EXTRA_EMAIL, new String[] { "[email protected]" });
intent.putExtra(Intent.EXTRA_SUBJECT, "subject");
intent.putExtra(Intent.EXTRA_TEXT, "mail body");
startActivity(Intent.createChooser(intent, ""));

The following should work and not require any permissions in the manifest (basically override shouldOverrideUrlLoading and handle links separately from tel, mailto, etc.):

    mWebView = (WebView) findViewById(R.id.web_view);

    WebSettings webSettings = mWebView.getSettings();
    webSettings.setJavaScriptEnabled(true);

    mWebView.setWebViewClient(new WebViewClient(){
        @Override
        public boolean shouldOverrideUrlLoading(WebView view, String url) {
            if( url.startsWith("http:") || url.startsWith("https:") ) {
                return false;
            }

            // Otherwise allow the OS to handle things like tel, mailto, etc.
            Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
            startActivity( intent );
            return true;
        }
    });
    mWebView.loadUrl(url);

Also, note that in the above snippet I am enabling JavaScript, which you will also most likely want, but if for some reason you don't, just remove those 2 lines.

I use below code to start a simple web server which render default html file if no file mentioned in Url.

var http = require('http'),
fs = require('fs'),
url = require('url'),
rootFolder = '/views/',
defaultFileName = '/views/5 Tips on improving Programming Logic   Geek Files.htm';


http.createServer(function(req, res){

    var fileName = url.parse(req.url).pathname;
    // If no file name in Url, use default file name
    fileName = (fileName == "/") ? defaultFileName : rootFolder + fileName;

    fs.readFile(__dirname + decodeURIComponent(fileName), 'binary',function(err, content){
        if (content != null && content != '' ){
            res.writeHead(200,{'Content-Length':content.length});
            res.write(content);
        }
        res.end();
    });

}).listen(8800);

It will render all js, css and image file, along with all html content.

Agree on statement "No content-type is better than a wrong one"

httpListener.Prefixes.Add("http://*:4444/");

you use "*" so you execute following cmd as admin

netsh http add urlacl url=http://*:4444/ user=username

no use +, must use *, because you spec *:4444~.

Another application for XOR is in circuits. It is used to sum bits.

When you look at a truth table:

 x | y | x^y
---|---|-----
 0 | 0 |  0     // 0 plus 0 = 0 
 0 | 1 |  1     // 0 plus 1 = 1
 1 | 0 |  1     // 1 plus 0 = 1
 1 | 1 |  0     // 1 plus 1 = 0 ; binary math with 1 bit

You can notice that the result of XOR is x added with y, without keeping track of the carry bit, the carry bit is obtained from the AND between x and y.

x^y // is actually ~xy + ~yx
    // Which is the (negated x ANDed with y) OR ( negated y ANDed with x ).

to open a local file or url with chrome, i used:

const open = require('open'); // npm i open
// open('http://google.com')
open('build_mytest/index.html', {app: "chrome.exe"})

Alternatively to information_schema it is possible to use pg_tables:

select * from pg_tables where schemaname='public';

I'm not clear on why you can't use PHP. You could then simply add and use variables as you wish, save the file as a PHP file and link to that .php file as the style sheet instead of the .css file.

It doesn't have to be PHP, but you get what I mean.

When we want programming stuff, why not use a programming language until CSS (maybe) supports things like variables?

Also, check out Nicole Sullivan's Object-oriented CSS.

And it worked:

You will have to connect your RDS through a computer which as mysql installed on it I used one of my hosting VPS using SSH

After i was logged in my VPS ( i used putty ) It was simple, in the prompt i entered the following command:

mysqladmin -h [YOUR RDS END POINT URL] -P 3306 -u [DB USER] -p flush-hosts

I needed to create a drag and drop + rotation that works on desktop, mobile, tablet including windows phone. The last one made it more complicated (mspointer vs. touch events).

The solution came from The great Greensock library

It took some jumping through hoops to make the same object draggable and rotatable but it works perfectly

Ask them how they ensure their pages continue to be usable when the user has JavaScript turned off or JavaScript isn't available.

There's no One True Answer, but you're fishing for an answer talking about some strategies for Progressive Enhancement.

Progressive Enhancement consists of the following core principles:

• basic content should be accessible to all browsers
• basic functionality should be accessible to all browsers
• sparse, semantic markup contains all content
• enhanced layout is provided by externally linked CSS
• enhanced behavior is provided by [[Unobtrusive JavaScript|unobtrusive]], externally linked JavaScript
• end user browser preferences are respected

Tested it and it worked for me. The element finding me change as per the document structure that you have.

If it gets into the selinux arena you've got a much more complicated issue. It's not a good idea to remove the selinux protection but to embrace it and use the tools that were designed to manage it.

If you are serving content out of /var/www/abc, you can verify the selinux permissions with a Z appended to the normal ls -l command. i.e. ls -laZ will give the selinux context.

To add a directory to be served by selinux you can use the semanage command like this. This will change the label on /var/www/abc to httpd_sys_content_t

semanage fcontext -a -t httpd_sys_content_t /var/www/abc

this will update the label for /var/www/abc

restorecon /var/www/abc 

This answer was taken from unixmen and modified to fit this question. I had been searching for this answer for a while and finally found it so felt like I needed to share somewhere. Hope it helps someone.

Regarding Phil Street's post:

It may actually be installed in your 32-bit program folder instead of your default x64, if you're running 64-bit OS. Check to see where 7-zip is installed, and if it is in Program Files (x86) then try using this instead:

PATH=%PATH%;C:\Program Files (x86)\7-Zip

For any Windows users still having this issue, this is what fixed it for me:

1. Run where create-react-app to get the path (mine was in C:\Users\username\AppData\Local\Yarn\bin).
2. Navigate to that directory and delete both "create-react-app" and "create-react-app.cmd".
3. Navigate to the directory you want to start a project in.
4. Run npm install create-react-app, npx create-react-app name-of-app, cd name-of-app, yarn start.

Step #4 will vary based on your configuration, but that's just what got me up and running.

Here is a very simple code in C++11 using boost::filesystem library to get file names in a directory (excluding folder names):

#include <string>
#include <iostream>
#include <boost/filesystem.hpp>
using namespace std;
using namespace boost::filesystem;

int main()
{
    path p("D:/AnyFolder");
    for (auto i = directory_iterator(p); i != directory_iterator(); i++)
    {
        if (!is_directory(i->path())) //we eliminate directories
        {
            cout << i->path().filename().string() << endl;
        }
        else
            continue;
    }
}

Output is like:

file1.txt
file2.dat

Layman's terms, it's dummy data (or fake data, test data...etc.) that you can use to test or develop your code against until you (or the other party) is ready to present/receive real data. It's a programmer's "Lorem Ipsum".

Employee database not ready? Make up a simple one with Jane Doe, John Doe...etc. API not ready? Make up a fake one by creating a static .json file containing fake data.

There's no way to allocate the whole thing in one go. Instead, create an array of pointers, then, for each pointer, create the memory for it. For example:

int** array;
array = (int**)malloc(sizeof(int*) * 50);
for(int i = 0; i < 50; i++)
    array[i] = (int*)malloc(sizeof(int) * 50);

Of course, you can also declare the array as int* array[50] and skip the first malloc, but the second set is needed in order to dynamically allocate the required storage.

It is possible to hack a way to allocate it in a single step, but it would require a custom lookup function, but writing that in such a way that it will always work can be annoying. An example could be L(arr,x,y,max_x) arr[(y)*(max_x) + (x)], then malloc a block of 50*50 ints or whatever and access using that L macro, e.g.

#define L(arr,x,y,max_x) arr[(y)*(max_x) + (x)]

int dim_x = 50;
int dim_y = 50;

int* array = malloc(dim_x*dim_y*sizeof(int));

int foo = L(array, 4, 6, dim_x);

But that's much nastier unless you know the effects of what you're doing with the preprocessor macro.

I've just set up a quick benchmarking exercise:

Function             time to run 1 million iterations
--------------------------------------------
(int) "123":                0.55029
intval("123"):              1.0115  (183%)

(int) "0":                  0.42461
intval("0"):                0.95683 (225%)

(int) int:                  0.1502
intval(int):                0.65716 (438%)

(int) array("a", "b"):      0.91264
intval(array("a", "b")):    1.47681 (162%)

(int) "hello":              0.42208
intval("hello"):            0.93678 (222%)

On average, calling intval() is two and a half times slower, and the difference is the greatest if your input already is an integer.

I'd be interested to know why though.

Update: I've run the tests again, this time with coercion (0 + $var)

| INPUT ($x)      |  (int) $x  |intval($x) |  0 + $x   |
|-----------------|------------|-----------|-----------|
| "123"           |   0.51541  |  0.96924  |  0.33828  |
| "0"             |   0.42723  |  0.97418  |  0.31353  |
| 123             |   0.15011  |  0.61690  |  0.15452  |
| array("a", "b") |   0.8893   |  1.45109  |  err!     |
| "hello"         |   0.42618  |  0.88803  |  0.1691   |
|-----------------|------------|-----------|-----------|

Addendum: I've just come across a slightly unexpected behaviour which you should be aware of when choosing one of these methods:

$x = "11";
(int) $x;      // int(11)
intval($x);    // int(11)
$x + 0;        // int(11)

$x = "0x11";
(int) $x;      // int(0)
intval($x);    // int(0)
$x + 0;        // int(17) !

$x = "011";
(int) $x;      // int(11)
intval($x);    // int(11)
$x + 0;        // int(11) (not 9)

_{Tested using PHP 5.3.1}

You change the title by changing the title of the view controller being displayed:

viewController.title = "some title"

Normally this is done in view did load on the view controller:

override func viewDidLoad() {
    super.viewDidLoad()
    self.title = "some title"
}

However, this only works if you have your view controller embedded in a UINavigationController. I highly recommend doing this instead of creating a navigation bar yourself. If you insist on creating a navigation bar yourself, you can change the title by doing:

navigationBar.topItem.title = "some title"

I think this is enough to get you on a nice path:

Sub a()
  Dim btn As Button
  Application.ScreenUpdating = False
  ActiveSheet.Buttons.Delete
  Dim t As Range
  For i = 2 To 6 Step 2
    Set t = ActiveSheet.Range(Cells(i, 3), Cells(i, 3))
    Set btn = ActiveSheet.Buttons.Add(t.Left, t.Top, t.Width, t.Height)
    With btn
      .OnAction = "btnS"
      .Caption = "Btn " & i
      .Name = "Btn" & i
    End With
  Next i
  Application.ScreenUpdating = True
End Sub

Sub btnS()
 MsgBox Application.Caller
End Sub

It creates the buttons and binds them to butnS(). In the btnS() sub, you should show your dialog, etc.

The solution I find is to use custom action Layout: Here is XML for menu.

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:Eventapp="http://schemas.android.com/apk/res-auto">
<!-- This is a comment. -->
    <item
        android:id="@+id/action_create"
        android:actionLayout="@layout/action_view_details_layout"
        android:orderInCategory="50"
        android:showAsAction = "always"/>
</menu>

The Layout is

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<TextView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="5dp"
    android:gravity="center"
    android:text="@string/create"/>

<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="5dp"
    android:paddingRight="5dp"
    android:gravity="center"
    android:src="@drawable/ic_action_v"/>

</LinearLayout>

this will show the icon and the text together.

To get the clickitem the the fragment or activity:

public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
    //super.onCreateOptionsMenu(menu, inflater);
    inflater.inflate(R.menu.menu_details_fragment, menu);
    View view = menu.findItem(R.id.action_create).getActionView();
    view.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(getActivity(), "Clicked", Toast.LENGTH_SHORT).show();
        }
    });
}

AppDomain.CurrentDomain.BaseDirectory

Addendum:

The important concept is that you are evaluating an expression in your Razor code. The best way to do this (if, for example, you are in a foreach loop) is using a generic method.

The syntax for calling a generic method in Razor is:

@(expression)

In this case, the expression is:

User.Identity.IsAuthenticated ? "auth" : "anon"

Therefore, the solution is:

@(User.Identity.IsAuthenticated ? "auth" : "anon")

This code can be used anywhere in Razor, not just for an html attribute.

See @Kyralessa 's comment for C# Razor Syntax Quick Reference (Phil Haack's blog).

Your code can be written as¹,

s = "Hello world," "nice to see you," "or not."

...but I doubt that's what you're looking for. In your case, you are probably looking for streams:

std::stringstream ss;
ss << "Hello world, " << 42 << "nice to see you.";
std::string s = ss.str();

¹ "can be written as" : This only works for string literals. The concatenation is done by the compiler.

if you want just the parts of url after http://domain.com, try this:

<?php echo $_SERVER['REQUEST_URI']; ?>

if the current url was http://domain.com/some-slug/some-id, echo will return only '/some-slug/some-id'.

if you want the full url, try this:

<?php echo 'http://' . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']; ?>

This maybe a bit off topic.

I was looking for a way to write this kind of information to the Docker log of my PHP-FPM container and came up with the snippet below. I'm sure this can be used by Docker PHP-FPM users.

fwrite(fopen('php://stdout', 'w'), var_export($object, true));

Using == to compare two enum values works, because there is only one object for each enum constant.

On a side note, there is actually no need to use == to write null-safe code, if you write your equals() like this:

public useEnums(final SomeEnum a) {
    if (SomeEnum.SOME_ENUM_VALUE.equals(a)) {
        …
    }
    …
}

This is a best practice known as Compare Constants From The Left that you definitely should follow.

You can put this code to make your code work with just single line of code

<input type="file" onchange="javascript:this.form.submit()">

This will upload the file on server without clicking on submit button

if you want to configure them in gradle it should look like

signingConfigs {
        debug {
            storeFile file('PATH_TO_HOME/.android/debug.keystore')
            storePassword 'android'                   
            keyAlias 'AndroidDebugKey'
            keyPassword 'android'                     
        }
        ...
}

My scenario was different after I tested all the possible options. If you have changed the ports and still get the same problem, well here's something you can try out. This was done in Windows 7.

Step 1: Confirm the cause of the error by going to Control Panel -> System and Security -> Administrative Tools -> Event Viewer -> Windows Logs -> Application -> Error. Mine said "The Apache service named reported the following error:

httpd.exe: Syntax error on line 424 of C:/xampp/apache/conf/httpd.conf: Cannot load c:\xampp\php\php5apache.dll into server: The specified module could not be found." So I needed to change \php5apache.dll to the version of my php and apache version installed which was php7apache2_4.dll

Step 2: To get the correct name for your .dll php and apache file, got to C:\xampp\php. You will see something like php7apache2_4.dll with other files in the folder.

Step 3: Go to C:/xampp/apache/conf/httpd.conf and edit the configuration file and change "c:\xampp\php\php5apache.dll" to "c:\xampp\php\php7apache2_4.dll" in my case. Make sure you open the file as administrator save changes made.

Step 4: Run the xampp server and everything should work fine. Do not forget to shut down the xampp server before doing the changes to the apache configuration file.

Hope this helps. Cheers! :)

You do not need to use substring at all since your format doesn't hold that info.

SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String fechaStr = "2013-10-10 10:49:29.10000";  
Date fechaNueva = format.parse(fechaStr);

System.out.println(format.format(fechaNueva)); // Prints 2013-10-10 10:49:29

• These methods are performance-engineered (they integrate with operating system native I/O).
• These methods work with files, directories and links.
• Each of the options supplied may be left out - they are optional.

Copying a directory or file

long bytes = java.nio.file.Files.copy( 
                 new java.io.File("<filepath1>").toPath(), 
                 new java.io.File("<filepath2>").toPath(),
                 java.nio.file.StandardCopyOption.REPLACE_EXISTING,
                 java.nio.file.StandardCopyOption.COPY_ATTRIBUTES,
                 java.nio.file.LinkOption.NOFOLLOW_LINKS);

Moving a directory or file

long bytes = java.nio.file.Files.move( 
                 new java.io.File("<filepath1>").toPath(), 
                 new java.io.File("<filepath2>").toPath(),
                 java.nio.file.StandardCopyOption.ATOMIC_MOVE,
                 java.nio.file.StandardCopyOption.REPLACE_EXISTING);

Copying a directory or file recursively

long bytes = com.yourcompany.nio.Files.copyRecursive( 
                 new java.io.File("<filepath1>").toPath(), 
                 new java.io.File("<filepath2>").toPath(),

                 java.nio.file.LinkOption.NOFOLLOW_LINKS );

For those interested in text alignment, a simple solution is to create a new class:

.text-right-large {
    text-align: right;
}
@media (max-width: 991px) {
    .text-right-large {
        text-align: left;
    }
}

Then add that class:

<div class="row">
    <div class="col-lg-6 col-md-6">elements 1</div>
    <div class="col-lg-6 col-md-6 text-right-large">
        elements 2
    </div>
</div>

When I was in grad school, we had a member of our research team who was blind. He was a bit older, maybe mid-40s. He told us about how he programmed his first computer (which was well before text-to-speech was common) to output the contents of the screen in Morse Code. To overcome the obvious chicken-and-egg problem, he had to completely rewrite the code each time through from scratch until it was working well enough for him to have it read back to him.

Now he uses text-to-speech, though he plans the code very thoroughly before actually writing any of it, to minimize the debug loop.

He was also pretty good at giving PowerPoint presentations that, despite his lack of sight, were just about as well formatted as any sighted presenter's.

To add to the other responses, sp_lock can also be used to dump full lock information on all running processes. The output can be overwhelming, but if you want to know exactly what is locked, it's a valuable one to run. I usually use it along with sp_who2 to quickly zero in on locking problems.

There are multiple different versions of "friendlier" sp_lock procedures available online, depending on the version of SQL Server in question.

In your case, for SQL Server 2005, sp_lock is still available, but deprecated, so it's now recommended to use the sys.dm_tran_locks view for this kind of thing. You can find an example of how to "roll your own" sp_lock function here.

There actually is a trick how to execute a parallel operation in a specific fork-join pool. If you execute it as a task in a fork-join pool, it stays there and does not use the common one.

final int parallelism = 4;
ForkJoinPool forkJoinPool = null;
try {
    forkJoinPool = new ForkJoinPool(parallelism);
    final List<Integer> primes = forkJoinPool.submit(() ->
        // Parallel task here, for example
        IntStream.range(1, 1_000_000).parallel()
                .filter(PrimesPrint::isPrime)
                .boxed().collect(Collectors.toList())
    ).get();
    System.out.println(primes);
} catch (InterruptedException | ExecutionException e) {
    throw new RuntimeException(e);
} finally {
    if (forkJoinPool != null) {
        forkJoinPool.shutdown();
    }
}

The trick is based on ForkJoinTask.fork which specifies: "Arranges to asynchronously execute this task in the pool the current task is running in, if applicable, or using the ForkJoinPool.commonPool() if not inForkJoinPool()"

As Nikolai has said you can use the gdb 'set' command to change the value of a variable.

You can also use the 'set' command to change memory locations. eg. Expanding on Nikolai's example:

(gdb) l
6       {
7           int i;
8           struct file *f, *ftmp;
9
(gdb) set variable i = 10
(gdb) p i
$1 = 10

(gdb) p &i
$2 = (int *) 0xbfbb0000
(gdb) set *((int *) 0xbfbb0000) = 20
(gdb) p i
$3 = 20

This should work for any valid pointer, and can be cast to any appropriate data type.

homes.sort(function(a,b) { return a.city - b.city } );
homes.sort(function(a,b){
    if (a.city==b.city){
        return parseFloat(b.price) - parseFloat(a.price);
    } else {
        return 0;
    }
});

You can update values from another table using inner join like this

UPDATE [table1_name] AS t1 INNER JOIN [table2_name] AS t2 ON t1.column1_name] = t2.[column1_name] SET t1.[column2_name] = t2.column2_name];

Follow here to know how to use this query http://www.voidtricks.com/mysql-inner-join-update/

or you can use select as subquery to do this

UPDATE [table_name] SET [column_name] = (SELECT [column_name] FROM [table_name] WHERE [column_name] = [value]) WHERE [column_name] = [value];

query explained in details here http://www.voidtricks.com/mysql-update-from-select/

You can use onLayout to get the width, height, and relative-to-parent position of a component at the earliest moment that they're available:

<View
  onLayout={event => {
    const layout = event.nativeEvent.layout;
    console.log('height:', layout.height);
    console.log('width:', layout.width);
    console.log('x:', layout.x);
    console.log('y:', layout.y);
  }}

Compared to using .measure() as shown in the accepted answer, this has the advantage that you'll never have to fiddle around deferring your .measure() calls with setTimeout to make sure that the measurements are available, but the disadvantage that it doesn't give you offsets relative to the entire page, only ones relative to the element's parent.

I've just encountered a bit different but similar situation. Not 100% sure if it'd be a resolution to your case, but I resolved the issue for Django 1.3 by setting a POST parameter 'csrfmiddlewaretoken' with the proper cookie value string which is usually returned within the form of your home HTML by Django's template system with '{% csrf_token %}' tag. I did not try on the older Django, just happened and resolved on Django1.3. My problem was that the first request submitted via Ajax from a form was successfully done but the second attempt from the exact same from failed, resulted in 403 state even though the header 'X-CSRFToken' is correctly placed with the CSRF token value as well as in the case of the first attempt. Hope this helps.

Yes;

git commit FILE

will commit just FILE. Then you can use

git reset --hard

to undo local changes in other files.

There may be other ways too that I don't know about...

edit: or, as NicDumZ said, git-checkout just the files you want to undo the changes on (the best solution depends on wether there are more files to commit or more files to undo :-)

http://blueimp.github.com/jQuery-File-Upload/ = great solution

According to their docs, the following browsers support drag & drop:

• Firefox 4+
• Safari 5+
• Google Chrome

First, you may want to install glances:

sudo apt-get install python-pip build-essential python-dev lm-sensors 
sudo pip install psutil logutils bottle batinfo https://bitbucket.org/gleb_zhulik/py3sensors/get/tip.tar.gz zeroconf netifaces pymdstat influxdb elasticsearch potsdb statsd pystache docker-py pysnmp pika py-cpuinfo bernhard
sudo pip install glances

Then run it in the terminal!

glances

In your Python code, add at the begin of the file, the following:

import os
import gc # Garbage Collector

After using the "Big" variable (for example: myBigVar) for which, you would like to release memory, write in your python code the following:

del myBigVar
gc.collect()

In another terminal, run your python code and observe in the "glances" terminal, how the memory is managed in your system!

Good luck!

P.S. I assume you are working on a Debian or Ubuntu system

It seems that the queries are not exactly the same. At least for MySQL.

Compare:

1. describe select distinct productname from northwind.products
2. describe select productname from northwind.products group by productname

The second query gives additionally "Using filesort" in Extra.

This value is from user's machine and it can be changed anytime so I think it doesn't matter, I just want to get an approximate value and then convert it to GMT in my server.

For example, I am from Taiwan and it returns "+8" for me.

Working example

JS

function timezone() {
    var offset = new Date().getTimezoneOffset();
    var minutes = Math.abs(offset);
    var hours = Math.floor(minutes / 60);
    var prefix = offset < 0 ? "+" : "-";
    return prefix+hours;
}


$('#result').html(timezone());

HTML

<div id="result"></div>

Result

+8

The outfile should be in binary mode.

So here is a simple example of how to use classes: Suppose you are a finance institute. You want your customer's accounts to be managed by a computer. So you need to model those accounts. That is where classes come in. Working with classes is called object oriented programming. With classes you model real world objects in your computer. So, what do we need to model a simple bank account? We need a variable that saves the balance and one that saves the customers name. Additionally, some methods to in- and decrease the balance. That could look like:

class bankaccount():
    def __init__(self, name, money):
        self.name = name
        self.money = money

    def earn_money(self, amount):
        self.money += amount

    def withdraw_money(self, amount):
        self.money -= amount

    def show_balance(self):
        print self.money

Now you have an abstract model of a simple account and its mechanism. The def __init__(self, name, money) is the classes' constructor. It builds up the object in memory. If you now want to open a new account you have to make an instance of your class. In order to do that, you have to call the constructor and pass the needed parameters. In Python a constructor is called by the classes's name:

spidermans_account = bankaccount("SpiderMan", 1000)

If Spiderman wants to buy M.J. a new ring he has to withdraw some money. He would call the withdraw method on his account:

spidermans_account.withdraw_money(100)

If he wants to see the balance he calls:

spidermans_account.show_balance()

The whole thing about classes is to model objects, their attributes and mechanisms. To create an object, instantiate it like in the example. Values are passed to classes with getter and setter methods like `earn_money()´. Those methods access your objects variables. If you want your class to store another object you have to define a variable for that object in the constructor.

Your constructor is expecting one parameter (data). You're not passing it in the call. I guess you wanted to initialise a field in the object. That would look like this:

class DHT:
    def __init__(self):
        self.data = {}
        self.data['one'] = '1'
        self.data['two'] = '2'
        self.data['three'] = '3'
    def showData(self):
        print(self.data)

if __name__ == '__main__':
    DHT().showData()

Or even just:

class DHT:
    def __init__(self):
        self.data = {'one': '1', 'two': '2', 'three': '3'}
    def showData(self):
        print(self.data)

You can also use CURRENT_TIMESTAMP, if you feel like being more ANSI compliant (though if you're porting code between database vendors, that'll be the least of your worries). It's exactly the same as GetDate() under the covers (see this question for more on that).

There's no ANSI equivalent for GetUTCDate(), however, which is probably the one you should be using if your app operates in more than a single time zone ...

I used $form.submit() as it keeps html input validation.

Also I used input type tel as it supported by mobile browsers, only display numeric keypad.

<input type="tel" minlength="10" maxlength="10" id="mobile" name="mobile" title="10 digit mobile number" required>


$('#mob_frm').submit(function(e) {
            e.preventDefault();
            if(!$('#mobile').val().match('[0-9]{10}'))  {
                alert("Please put 10 digit mobile number");
                return;
            }  

        });

Set the value it will set it as selected option for dropdown:

$("#salesrep").val("Bruce Jones");

Here is working Demo

If it still not working:

1. Please check JavaScript errors on console.
2. Make sure you included jquery files
3. your network is not blocking jquery file if using externally.
4. Check your view source some time exact copy of element stop jquery to work correctly

This method takes all views inside a layout, this is similar to Alexander Kulyakhtin's answer. The difference is, it accepts any type of parent layouts & returns an Array List of views.

public List<View> getAllViews(ViewGroup layout){
        List<View> views = new ArrayList<>();
        for(int i =0; i< layout.getChildCount(); i++){
            views.add(layout.getChildAt(i));
        }
        return views;
}

If anyone is using SQL and they have meta tags there and still the error is shown, this happens because of your connection from .net to SQL.

In you appsettings.json update your connection string to have: Persist Security Info=True. So your connection string should look like this:

"DefaultConnection": "Server=[[server]];Initial Catalog=[[db]];Persist Security Info=True;User ID=[[user]];Password=[[pass]];MultipleActiveResultSets=False;Encrypt=True;TrustServerCertificate=False;Connection Timeout=30;"

This will direct everything from the old host to the root of the new host:

RewriteEngine on
RewriteCond %{http_host} ^www.old.com [NC,OR]
RewriteCond %{http_host} ^old.com [NC]
RewriteRule ^(.*)$ http://www.thenewdomain.org/ [R=301,NC,L]

The XPath turns into this:

Get me all of the div elements that have an id equal to container.

As for getting the first etc, you have two options.

Turn it into a .findElement() - this will just return the first one for you anyway.

or

To explicitly do this in XPath, you'd be looking at:

(//div[@id='container'])[1]

for the first one, for the second etc:

(//div[@id='container'])[2]

Then XPath has a special indexer, called last, which would (you guessed it) get you the last element found:

(//div[@id='container'])[last()]

Worth mentioning that XPath indexers will start from 1 not 0 like they do in most programming languages.

As for getting the parent 'node', well, you can use parent:

//div[@id='container']/parent::*

That would get the div's direct parent.

You could then go further and say I want the first *div* with an id of container, and I want his parent:

(//div[@id='container'])[1]/parent::*

Hope that helps!

Wikipedia says:

Method overriding, in object oriented programming, is a language feature that allows a subclass or child class to provide a specific implementation of a method that is already provided by one of its superclasses or parent classes.

In detail, when you have an object foo that has a void hello() function:

class foo {
    virtual void hello(); // Code : printf("Hello!");
}

A child of foo, will also have a hello() function:

class bar : foo {
    // no functions in here but yet, you can call
    // bar.hello()
}

However, you may want to print "Hello Bar!" when hello() function is being called from a bar object. You can do this using override

class bar : foo {
    virtual void hello() override; // Code : printf("Hello Bar!");
}

To start redis with a config file all you need to do is specifiy the config file as an argument:

redis-server /root/config/redis.rb

Instead of using and killing PID's I would suggest creating an init script for your service

I would suggest taking a look at the Installing Redis more properly section of http://redis.io/topics/quickstart. It will walk you through setting up an init script with redis so you can just do something like service redis_server start and service redis_server stop to control your server.

I am not sure exactly what distro you are using, that article describes instructions for a Debian based distro. If you are are using a RHEL/Fedora distro let me know, I can provide you with instructions for the last couple of steps, the config file and most of the other steps will be the same.

A relatively newer (de)compression tool you might want to consider is zstandard. It does an excellent job of utilizing spare cores, and it has made some great trade-offs when it comes to compression ratio vs. (de)compression time. It is also highly tweak-able depending on your compression ratio needs.

Using the Split function seems more elegant than InStr and Left, in my opinion.

Private Sub CommandButton2_Click()


Dim ThisFileName As String
Dim BaseFileName As String

Dim FileNameArray() As String

ThisFileName = ThisWorkbook.Name
FileNameArray = Split(ThisFileName, ".")
BaseFileName = FileNameArray(0)

MsgBox "Base file name is " & BaseFileName

End Sub

For JQuery 1.7+ use:

$('input[type=checkbox]').on('change', function() {
  ...
});

In case you want to pass in a block, say, for a glyphicon button, as in the following:

<%= link_to my_url, class: "stuff" do %>
  <i class="glyphicon glyphicon-inbox></i> Nice glyph-button
<% end %>

Then passing querystrings params could be accomplished through:

<%= link_to url_for(params.merge(my_params: "value")), class: "stuff" do %>
  <i class="glyphicon glyphicon-inbox></i> Nice glyph-button
<% end %>

Note that if there are ties in top 10 values, you will only get the top 10 rows, not the top 10 values with the answers provided. Ex: if the top 5 values are 10, 11, 12, 13, 14, 15 but your data contains 10, 10, 11, 12, 13, 14, 15 you will only get 10, 10, 11, 12, 13, 14 as your top 5 with a LIMIT

Here is a solution which will return more than 10 rows if there are ties but you will get all the rows where some_value_column is technically in the top 10.

select
  *
from
  (select
     *,
     rank() over (order by some_value_column desc) as my_rank
  from mytable) subquery
where my_rank <= 10

Bind them using jQuery and make jQuery handle it: http://jsfiddle.net/ZmxpW/.

$('select').change(function() {
    $(this).parents('form').submit();
});

This is caused because of trying to execute an INSERT or UPDATE statement that has created a duplicate value in a field restricted by a unique index.

You can resolve this either by

• changing the constraint to allow duplicates, or
• drop the unique constraint or you can change your SQL to avoid duplicate inserts

The selected answer doesn't always ensure that HTML is stripped, as it's still possible to construct an invalid HTML string through it by crafting a string like the following.

  "<<h1>h1>foo<<//</h1>h1/>"

This input will ensure that the stripping assembles a set of tags for you and will result in:

  "<h1>foo</h1>"

additionally jquery's text function will strip text not surrounded by tags.

Here's a function that uses jQuery but should be more robust against both of these cases:

var stripHTML = function(s) {
    var lastString;

    do {            
        s = $('<div>').html(lastString = s).text();
    } while(lastString !== s) 

    return s;
};

Although this is the accepted answer, toto_tico's answer below is better :)

Try making the onclick js use 'return' to ensure the desired return value gets used...

<button type="button" value="click me" onclick="return check_me();" />

The preferred way to get the length of any python object is to pass it as an argument to the len function. Internally, python will then try to call the special __len__ method of the object that was passed.

The Ansible 'user' module manages users, in the idempotent way. In the playbook below the first task declares state=present for the user. Note that 'register: newuser' in the first action helps the second action to determine if the user is new (newuser.changed==True) or existing (newuser.changed==False), to only generate the password once.

The Ansible playbook has:

tasks:
  - name: create deployment user
    user: 
      name: deployer 
      createhome: yes 
      state: present 
    register: newuser

  - name: generate random password for user only on creation
    shell: /usr/bin/openssl rand -base64 32 | passwd --stdin deployer
    when: newuser.changed

i know this is an old post, but i wanted to provide a JQuery plugin version and my code.

// Find the first occurrence of object in list, Similar to $.grep, but stops searching 
function findFirst(a,b){
var i; for (i = 0; i < a.length; ++i) { if (b(a[i], i)) return a[i]; } return undefined;
}

usage:

var product = $.findFirst(arrProducts, function(p) { return p.id == 10 });

If I understand your question correctly, I've made a fiddle that has this working correctly. This issue is with how you're assigning the event handlers and as others have said you have over riding event handlers. The current jQuery best practice is to use on() to register event handlers. Here's a link to the jQuery docs about on: link

Your original solution was pretty close but the way you added the event handlers is a bit confusing. It's considered best practice to not add events to HTML elements. I recommend reading up on Unobstrusive JavaScript.

Here's the JavaScript code. I added a counter variable so you can see that it is working correctly.

$('#answer').on('click', function() {
  feedback('hey there');
});

var counter = 0;

function feedback(message) {

  $('#feedback').remove();

  $('.answers').append('<div id="feedback">' + message + ' ' + counter + '</div>');

  counter++;    
}

How about the List.FindIndex Method:

int index = myList.FindIndex(a => a.Prop == oProp);

This method performs a linear search; therefore, this method is an O(n) operation, where n is Count.

If the item is not found, it will return -1

For those who are trying to get an X Window application working from Windows from Linux:

What worked for me was to setup xming server on my windows machine, set X11 forwarding option in putty when I connect to the linux host and put in my windows ip address with the display port and then the display variable with my windows IP address:0.0

Dont forget to add the linux hosts IP address to the X0.hosts file to ensure that the xming server accepts traffic from that host. Took me a while to figure that out.

My answer is inspired by Jeffrey's answer. Where that answer gives a more abstract solution, I try to provide more concrete steps on how to potentially implement it. This is simply a guide, one that can be implemented more elegantly. For a more detailed example check out this tutorial by MDN web docs.

HTML:

<div id="zoom_here">....</div>

JS

<script>
var dist1=0;
function start(ev) {
           if (ev.targetTouches.length == 2) {//check if two fingers touched screen
               dist1 = Math.hypot( //get rough estimate of distance between two fingers
                ev.touches[0].pageX - ev.touches[1].pageX,
                ev.touches[0].pageY - ev.touches[1].pageY);

    function move(ev) {
           if (ev.targetTouches.length == 2 && ev.changedTouches.length == 2) {
                 // Check if the two target touches are the same ones that started
               var dist2 = Math.hypot(//get rough estimate of new distance between fingers

Solution 1 : Creation of a JniLibs folder

Create a folder called “jniLibs” into your app and the folders containing your *.so inside. The "jniLibs" folder needs to be created in the same folder as your "Java" or "Assets" folders.

Solution 2 : Modification of the build.gradle file

If you don’t want to create a new folder and keep your *.so files into the libs folder, it is possible !

In that case, just add your *.so files into the libs folder (please respect the same architecture as the solution 1 : libs/armeabi/.so for instance) and modify the build.gradle file of your app to add the source directory of the jniLibs.

sourceSets {
    main {
        jniLibs.srcDirs = ["libs"]
    }
}

You will have more explanations, with screenshots to help you here ( Step 6 ):

http://blog.guillaumeagis.eu/setup-andengine-with-android-studio/

EDIT It had to be jniLibs.srcDirs, not jni.srcDirs - edited the code. The directory can be a [relative] path that points outside of the project directory.

Your usecase is basically only relevant for when doing arrays and matrixes of a fixed length, so that you know how long they are before hand. In that case you typically also create them before hand filling them up with None or 0, so that in fact any index you will use already exists.

You could say this: I need .get() on dictionaries quite often. After ten years as a full time programmer I don't think I have ever needed it on a list. :)

Here is the version that I created of @Kindall's answer https://stackoverflow.com/a/6894023/12900787

This version makes it so that all you have to do is input your command with arguments to create the new thread.

(I have also included a couple of tests)

this was made with python 3.8

from threading import Thread
from typing import Any


#def threader(com):  # my original Version (Ignore this)
#    try:
#        threader = Thread(target = com)
#        threader.start()
#    except Exception as e:
#        print(e)
#        print('Could not start thread')


def test(plug, plug2, plug3):
    print(f"hello {plug}")
    print(f'I am the second plug : {plug2}')
    print(plug3)
    return 'I am the return Value!'


def test2(msg):
    return f'I am from the second test: {msg}'


def test3():
    print('hello world')


def NewThread(com, Returning: bool, *arguments) -> Any:
    """
    Will create a new thread for a function/command.

    :param com: Command to be Executed
    :param arguments: Arguments to be sent to Command
    :param Returning: True/False Will this command need to return anything
    """
    
    class NewThreadWorker(Thread):
        def __init__(self, group = None, target = None, name = None, args = (), kwargs = None, *,
                     daemon = None):
            Thread.__init__(self, group, target, name, args, kwargs, daemon = daemon)
            
            self._return = None
        
        def run(self):
            if self._target is not None:
                self._return = self._target(*self._args, **self._kwargs)
        
        def join(self):
            Thread.join(self)
            return self._return
    
    ntw = NewThreadWorker(target = com, args = (*arguments,))
    ntw.start()
    if Returning:
        return ntw.join()


if __name__ == "__main__":
    # threader(test('world'))
    print(NewThread(test, True, 'hi', 'test', test2('hi')))
    NewThread(test3, True)

Hope that this is useful to someone :)

Unutbu gave a really complete answer (they got a +1 from me too), but here is a lo-tech alternative:

>>> x=np.random.randn(5)
>>> x
array([ 0.25276524,  2.28334499, -1.88221637,  0.69949927,  1.0285625 ])
>>> ['{:.2f}'.format(i) for i in x]
['0.25', '2.28', '-1.88', '0.70', '1.03']

As a function (using the format() syntax for formatting):

def ndprint(a, format_string ='{0:.2f}'):
    print [format_string.format(v,i) for i,v in enumerate(a)]

Usage:

>>> ndprint(x)
['0.25', '2.28', '-1.88', '0.70', '1.03']

>>> ndprint(x, '{:10.4e}')
['2.5277e-01', '2.2833e+00', '-1.8822e+00', '6.9950e-01', '1.0286e+00']

>>> ndprint(x, '{:.8g}')
['0.25276524', '2.283345', '-1.8822164', '0.69949927', '1.0285625']

The index of the array is accessible in the format string:

>>> ndprint(x, 'Element[{1:d}]={0:.2f}')
['Element[0]=0.25', 'Element[1]=2.28', 'Element[2]=-1.88', 'Element[3]=0.70', 'Element[4]=1.03']

I can't tell if you've found some special case code which requires you to test against private fields. But in my experience you never have to test something private - always public. Maybe you could give an example of some code where you need to test private?

Say your project is structured this way:

+---MyPythonProject
|   +---.gitignore
|   +---run.py
|   |   +---subscripts
|   |   |   +---script_one.py
|   |   |   +---script_two.py

Inside run.py, you can import scripts one and two by:

from subscripts import script_one as One
from subscripts import script_two as Two

Now, still inside run.py, you'll be able to call their methods with:

One.method_from_one(param)
Two.method_from_two(other_param)

As of Excel 2019 you could do this. The "Error" at the end is the default.

SWITCH(LEFT(A1,1), "A", "Pick Up", "B", "Collect", "C", "Prepaid", "Error")

python: read lines from compressed text files

Using gzip.GzipFile:

import gzip

with gzip.open('input.gz','r') as fin:        
    for line in fin:        
        print('got line', line)

First make your template into a jQuery object:

 var template = $("<li><div class='bar'>bla</div></li>");

Then set the attributes and append it to the DOM.

 template.find('li').attr('id','1234');
 $(document.body).append(template);

Note that it however makes no sense at all to add a li directly to the DOM since li should always be children of ul or ol. Also it is better to not make jQuery parse raw HTML. Instead create a li, set its attributes. Create a div and set it's attributes. Insert the div into the li and then append the li to the DOM.

Expanding off of what @twalberg and @iconoclast had, if you're using cmd for whatever reason, you can use:

FOR /F "usebackq" %x IN (`"git branch | grep '*' | cut -f2 -d' '"`) DO FOR /F "usebackq" %y IN (`"git merge-base %x master"`) DO git diff --name-only %x %y

The simplest solution is to completely disable security - change true to false in /var/lib/jenkins/config.xml file.

<useSecurity>true</useSecurity>

Then just restart Jenkins, by

sudo service jenkins restart

And then go to admin panel and set everything once again.

If you in case are running your Jenkins inside k8s pod from a docker, which is my case and can not run service command, then you can just restart Jenkins by deleting the pod:

kubectl delete pod <jenkins-pod-name>

Once the command was issued, the k8s will terminate the old pod and start a new one.

Flurry Support for iPhone 5 (ARMv7s) As I mentioned in yesterday’s post, Flurry started working on a version of the iOS SDK to support the ARMv7s processor in the new iPhone 5 immediately after the announcement on Wednesday.

I am happy to tell you that the work is done and the SDK is now available on the site.
