datetime.timedelta is just the difference between two datetimes ... so it's like a period of time, in days / seconds / microseconds

>>> import datetime
>>> a = datetime.datetime.now()
>>> b = datetime.datetime.now()
>>> c = b - a

>>> c
datetime.timedelta(0, 4, 316543)
>>> c.days
0
>>> c.seconds
4
>>> c.microseconds
316543

Be aware that c.microseconds only returns the microseconds portion of the timedelta! For timing purposes always use c.total_seconds().

You can do all sorts of maths with datetime.timedelta, eg:

>>> c / 10
datetime.timedelta(0, 0, 431654)

It might be more useful to look at CPU time instead of wallclock time though ... that's operating system dependant though ... under Unix-like systems, check out the 'time' command.

you can use Array.select or Array.index to do that.

If you need to call the same method from both Activities why not then use a third object?

public class FirstActivity extends Activity 
{  

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main2);

    }      

    // Utility.method() used somewhere in FirstActivity
}

public class Utility {

    public static void method()
    {

    }  

}

public class SecondActivity extends Activity 
{  

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main2);

        Utility.method();

    }
}

Of course making it static depends on the use case.

Update May 2020, installed Anaconda 3 Individual Edition from https://www.anaconda.com/products/individual, chose 32-bit installer for Python 3.7, and installed with Default options.

Here is the directory where Anaconda was installed (C:\ProgramData\Anaconda3). Note ProgramData is a hidden folder not visible via Windows File Explorer.

And launching Anaconda command prompt from Start Menu>>Anaconda3 gives below command shell

"where anaconda" command gives below output C:\ProgramData\Anaconda3\Scripts\anaconda.exe and versions for anaconda, conda, python

Updated original question which was asked 3 years ago, and is relevant today as well in May 2020 as I had similar question/doubt when installing Anaconda recently.

I use Telegram.Bot and got the ID the following way:

1. Add the bot to the channel
2. Run the bot
3. Write something into the channel (eg: /authenticate or foo)

Telegram.Bot:

private static async Task Main()
{
    var botClient = new TelegramBotClient("key");
    botClient.OnUpdate += BotClientOnOnUpdate;
    Console.ReadKey();
}

private static async void BotClientOnOnUpdate(object? sender, UpdateEventArgs e)
{
    var id = e.Update.ChannelPost.Chat.Id;
    await botClient.SendTextMessageAsync(new ChatId(id), $"Hello World! Channel ID is {id}");
}

Plain API:

This translates to the getUpdates method in the plain API, which has an array of Update which then contains channel_post.chat.id

Try this if the above solution aren't working, worked for me

Cut the whole contents in the worksheet using "Ctrl + A" followed by "Ctrl + X" and paste it to a new sheet. Your reference to formulas will remain intact when you cut paste.

BUT imagine a large table with changing columns. You have to compare every column and if the database changes you have to adjust the trigger. AND it doesn't "feel" good to compare every row hardcoded :)

Yeah, but that's the way to proceed.

As a side note, it's also good practice to pre-emptively check before updating:

UPDATE foo SET b = 3 WHERE a=3 and b <> 3;

In your example this would make it update (and thus overwrite) two rows instead of three.

For batch processing with files in folder aiming for 190 VBR and file extension = .mp3 instead of .ac3.mp3 you can use the following code

Change .ac3 to whatever the source audio format is.

ffmpeg mp3 settings

for f in *.ac3 ; do ffmpeg -i "$f" -acodec libmp3lame -q:a 2 "${f%.*}.mp3"; done

What's going on? Python modules can be part written in C or C++ (typically for speed). If you try to install such a package with Pip (or setup.py), it has to compile that C/C++ from source. Out the box, Pip will brazenly assume you the compiler Microsoft Visual C++ installed. If you don't have it, you'll see this cryptic error message "Error: Unable to find vcvarsall.bat".

The prescribed solution is to install a C/C++ compiler, either Microsoft Visual C++, or MinGW (an open-source project). However, installing and configuring either is prohibitively difficult. (Edit 2014: Microsoft have published a special C++ compiler for Python 2.7)

The easiest solution is to use Christoph Gohlke's Windows installers (.msi) for popular Python packages. He builds installers for Python 2.x and 3.x, 32 bit and 64 bit. You can download them from http://www.lfd.uci.edu/~gohlke/pythonlibs/

If you too think "Error: Unable to find vcvarsall.bat" is a ludicrously cryptic and unhelpful message, then please comment on the bug at http://bugs.python.org/issue2943 to replace it with a more helpful and user-friendly message.

For comparison, Ruby ships with a package manager Gem and offers a quasi-official C/C++ compiler, DevKit. If you try to install a package without it, you see this helpful friendly useful message:

Please update your PATH to include build tools or download the DevKit from http://rubyinstaller.org/downloads and follow the instructions at http://github.com/oneclick/rubyinstaller/wiki/Development-Kit

I asked a question that kinda duplicated on this topic a while back, and after excessive research, and seeing a lot of information missing that should be here, I feel I have something valuable to add to this older post.

• Firstly I want to address that there are several ways to obtain the value of a property and store it in a dynamic Variable. The first most popular, and easiest way IMHO would be:

let properyValue = element.style['enter-a-property'];

however I rarely go this route because it doesn't work on property values assigned via style-sheets. To give you an example, I'll demonstrate with a bit of pseudo code.

 let elem = document.getElementById('someDiv');
 let cssProp = elem.style['width'];

Using the code example above; if the width property of the div element that was stored in the 'elem' variable was styled in a CSS style-sheet, and not styled inside of its HTML tag, you are without a doubt going to get a return value of undefined stored inside of the cssProp variable. The undefined value occurs because in-order to get the correct value, the code written inside a CSS Style-Sheet needs to be computed in-order to get the value, therefore; you must use a method that will compute the value of the property who's value lies within the style-sheet.

• Henceforth the getComputedStyle() method!

function getCssProp(){
  let ele = document.getElementById("test");
  let cssProp = window.getComputedStyle(ele,null).getPropertyValue("width");
}

W3Schools getComputedValue Doc This gives a good example, and lets you play with it, however, this link Mozilla CSS getComputedValue doc talks about the getComputedValue function in detail, and should be read by any aspiring developer who isn't totally clear on this subject.

• As a side note, the getComputedValue method only gets, it does not set. This, obviously is a major downside, however there is a method that gets from CSS style-sheets, as well as sets values, though it is not standard Javascript. The JQuery method...

$(selector).css(property,value)

...does get, and does set. It is what I use, the only downside is you got to know JQuery, but this is honestly one of the very many good reasons that every Javascript Developer should learn JQuery, it just makes life easy, and offers methods, like this one, which is not available with standard Javascript. Hope this helps someone!!!

Rather than using sub queries in where condition which will increase the query time where records are huge.

I would suggest to use Inner Join as a better option to this problem.

Considering the same table this could give the result

SELECT EmailAddress, CustomerName FROM Customers as a 
Inner Join Customers as b on a.CustomerName <> b.CustomerName and a.EmailAddress = b.EmailAddress

For still better results I would suggest you to use CustomerID or any unique field of your table. Duplication of CustomerName is possible.

You don't actually need LINQ for this because List<T> provides a method that does exactly what you want: Find.

Searches for an element that matches the conditions defined by the specified predicate, and returns the first occurrence within the entire List<T>.

Example code:

PricePublicModel result = pricePublicList.Find(x => x.Size == 200);

Well, just to be different, I found an article that references using Reflection.Emit to do so.

Here's the link: http://www.codeproject.com/KB/cs/dotnetattributes.aspx , you will also want to look into some of the comments at the bottom of the article, because possible approaches are discussed.

A simple way but dangerous way to do this would be to use eval(). eval() executes the string passed to it as code. The dangerous thing about this is that if this string is gained from user input, they could maliciously execute code that could break the computer. I would get the input, check it with a regex, and then execute it if you determine if it's OK. If it's only going to be in the format "number operation number", then you could use a simple regex:

import re
s = raw_input('What is your math problem? ')
if re.findall('\d+? *?\+ *?\d+?', s):
  print eval(s)
else:
  print "Try entering a math problem"

Otherwise, you would have to come up with something a bit stricter than this. You could also do it conversely, using a regex to find if certain things are not in it, such as numbers and operations. Also you could check to see if the input contains certain commands.

What is the purpose of this

 names = list;

? Also, no ; required in Python.

Do you want

 names = []

or

 names = list()

at the start of your program instead? Though given your particular code, there's no need for this statement to create this names variable since you do so later when you read data into it from your file.

@JBernardo has already pointed out the other (and more major) problem with the code.

This worked for me and does not require background color behind the text to hide a border line, instead uses actual hr tag. You can play around with the widths to get different sizes of hr lines.

<div>
    <div style="display:inline-block;width:45%"><hr width='80%' /></div>
    <div style="display:inline-block;width: 9%;text-align: center;vertical-align:90%;text-height: 24px"><h4>OR</h4></div>
    <div style="display:inline-block;width:45%;float:right" ><hr width='80%'/></div>
</div>

Using COUNT instead of SUM removes the requirement for an ELSE statement:

SELECT jobId, jobName,
    COUNT(CASE WHEN Priority=1 THEN 1 END) AS Priority1,
    COUNT(CASE WHEN Priority=2 THEN 1 END) AS Priority2,
    COUNT(CASE WHEN Priority=3 THEN 1 END) AS Priority3,
    COUNT(CASE WHEN Priority=4 THEN 1 END) AS Priority4,
    COUNT(CASE WHEN Priority=5 THEN 1 END) AS Priority5
FROM TableName
GROUP BY jobId, jobName

^{Assuming you actually mean timestamp because there is no datetime in Postgres}

Cast the timestamp column to a date, that will remove the time part:

select *
from the_table
where the_timestamp_column::date = date '2015-07-15';

This will return all rows from July, 15th.

Note that the above will not use an index on the_timestamp_column. If performance is critical, you need to either create an index on that expression or use a range condition:

select *
from the_table
where the_timestamp_column >= timestamp '2015-07-15 00:00:00'
  and the_timestamp_column < timestamp '2015-07-16 00:00:00';

there is a simpler way of checking if a variable is an integer. you can use $.isNumeric() function. e.g.

$.isNumeric( 10 );     // true

this will return true but if you put a string in place of the 10, you will get false.

I hope this works for you.

This thread was very helpful to get some insights how backups of git repos could be done. I think it still lacks some hints, information or conclusion to find the "correct way" (tm) for oneself. Therefore sharing my thoughts here to help others and put them up for discussions to enhance them. Thanks.

So starting with picking-up the original question:

• Goal is to get as close as possible to a "full" backup of a git repository.

Then enriching it with the typical wishes and specifiying some presettings:

• Backup via a "hot-copy" is preferred to avoid service downtime.
• Shortcomings of git will be worked around by additional commands.
• A script should do the backup to combine the multiple steps for a single backup and to avoid human mistakes (typos, etc.).
• Additionally a script should do the restore to adapt the dump to the target machine, e.g. even the configuration of the original machine may have changed since the backup.
• Environment is a git server on a Linux machine with a file system that supports hardlinks.

1. What is a "full" git repo backup?

The point of view differs on what a "100%" backup is. Here are two typical ones.

#1 Developer's point of view

• Content
• References

git is a developer tool and supports this point of view via git clone --mirror and git bundle --all.

#2 Admin's point of view

• Content files
  • Special case "packfile": git combines and compacts objects into packfiles during garbage collection (see git gc)
• git configuration
  • see https://git-scm.com/book/en/v2/Git-Internals-Plumbing-and-Porcelain
  • docs: man git-config, man gitignore
  • .git/config
  • .git/description (for hooks and tools, e.g. post-receive-email hook, gitolite, GitWeb, etc.)
  • .git/hooks/
  • .git/info/ (repository exclude file, etc.)
• Optional: OS configuration (file system permissions, etc.)

git is a developer tool and leaves this to the admin. Backup of the git configuration and OS configuration should be seen as separated from the backup of the content.

2. Techniques

• "Cold-Copy"
  • Stop the service to have exclusive access to its files. Downtime!
• "Hot-Copy"
  • Service provides a fixed state for backup purposes. On-going changes do not affect that state.

3. Other topics to think about

Most of them are generic for backups.

• Is there enough space to hold the full backups? How many generations will be stored?
• Is an incremental approach wanted? How many generations will be stored and when to create a full backup again?
• How to verify that a backup is not corrupted after creation or over time?
• Does the file system support hardlinks?
• Put backup into a single archive file or use directory structure?

4. What git provides to backup content

• git gc --auto

  • docs: man git-gc
  • Cleans up and compacts a repository.

• git bundle --all

  • docs: man git-bundle, man git-rev-list
  • Atomic = "Hot-Copy"
  • Bundles are dump files and can be directly used with git (verify, clone, etc.).
  • Supports incremental extraction.
  • Verifiable via git bundle verify.

• git clone --mirror

  • docs: man git-clone, man git-fsck, What's the difference between git clone --mirror and git clone --bare
  • Atomic = "Hot-Copy"
  • Mirrors are real git repositories.
  • Primary intention of this command is to build a full active mirror, that periodically fetches updates from the original repository.
  • Supports hardlinks for mirrors on same file system to avoid wasting space.
  • Verifiable via git fsck.
  • Mirrors can be used as a basis for a full file backup script.

5. Cold-Copy

A cold-copy backup can always do a full file backup: deny all accesses to the git repos, do backup and allow accesses again.

• Possible Issues
  • May not be easy - or even possible - to deny all accesses, e.g. shared access via file system.
  • Even if the repo is on a client-only machine with a single user, then the user still may commit something during an automated backup run :(
  • Downtime may not be acceptable on server and doing a backup of multiple huge repos can take a long time.
• Ideas for Mitigation:
  • Prevent direct repo access via file system in general, even if clients are on the same machine.
  • For SSH/HTTP access use git authorization managers (e.g. gitolite) to dynamically manage access or modify authentication files in a scripted way.
  • Backup repos one-by-one to reduce downtime for each repo. Deny one repo, do backup and allow access again, then continue with the next repo.
  • Have planned maintenance schedule to avoid upset of developers.
  • Only backup when repository has changed. Maybe very hard to implement, e.g. list of objects plus having packfiles in mind, checksums of config and hooks, etc.

6. Hot-Copy

File backups cannot be done with active repos due to risk of corrupted data by on-going commits. A hot-copy provides a fixed state of an active repository for backup purposes. On-going commits do not affect that copy. As listed above git's clone and bundle functionalities support this, but for a "100% admin" backup several things have to be done via additional commands.

"100% admin" hot-copy backup

• Option 1: use git bundle --all to create full/incremental dump files of content and copy/backup configuration files separately.
• Option 2: use git clone --mirror, handle and copy configuration separately, then do full file backup of mirror.
  • Notes:
  • A mirror is a new repository, that is populated with the current git template on creation.
  • Clean up configuration files and directories, then copy configuration files from original source repository.
  • Backup script may also apply OS configuration like file permissions on the mirror.
  • Use a filesystem that supports hardlinks and create the mirror on the same filesystem as the source repository to gain speed and reduce space consumption during backup.

7. Restore

• Check and adopt git configuration to target machine and latest "way of doing" philosophy.
• Check and adopt OS configuration to target machine and latest "way of doing" philosophy.

Use reference wherever you can, pointers wherever you must.

Avoid pointers until you can't.

The reason is that pointers make things harder to follow/read, less safe and far more dangerous manipulations than any other constructs.

So the rule of thumb is to use pointers only if there is no other choice.

For example, returning a pointer to an object is a valid option when the function can return nullptr in some cases and it is assumed it will. That said, a better option would be to use something similar to std::optional (requires C++17; before that, there's boost::optional).

Another example is to use pointers to raw memory for specific memory manipulations. That should be hidden and localized in very narrow parts of the code, to help limit the dangerous parts of the whole code base.

In your example, there is no point in using a pointer as argument because:

1. if you provide nullptr as the argument, you're going in undefined-behaviour-land;
2. the reference attribute version doesn't allow (without easy to spot tricks) the problem with 1.
3. the reference attribute version is simpler to understand for the user: you have to provide a valid object, not something that could be null.

If the behaviour of the function would have to work with or without a given object, then using a pointer as attribute suggests that you can pass nullptr as the argument and it is fine for the function. That's kind of a contract between the user and the implementation.

Save the commands in a .SQL file, ex: ClearTables.sql, say in your C:\temp folder.

Contents of C:\Temp\ClearTables.sql

Delete from TableA;
Delete from TableB;
Delete from TableC;
Delete from TableD;
Delete from TableE;

Then use sqlcmd to execute it as follows. Since you said the database is remote, use the following syntax (after updating for your server and database instance name).

sqlcmd -S <ComputerName>\<InstanceName> -i C:\Temp\ClearTables.sql

For example, if your remote computer name is SQLSVRBOSTON1 and Database instance name is MyDB1, then the command would be.

sqlcmd -E -S SQLSVRBOSTON1\MyDB1 -i C:\Temp\ClearTables.sql

Also note that -E specifies default authentication. If you have a user name and password to connect, use -U and -P switches.

You will execute all this by opening a CMD command window.

Using a Batch File.

If you want to save it in a batch file and double-click to run it, do it as follows.

Create, and save the ClearTables.bat like so.

echo off
sqlcmd -E -S SQLSVRBOSTON1\MyDB1 -i C:\Temp\ClearTables.sql
set /p delExit=Press the ENTER key to exit...:

Then double-click it to run it. It will execute the commands and wait until you press a key to exit, so you can see the command output.

For those who want to have the accepted answer run in Ansible without further searches, I post the task here for convenience and future reference.

Accepted answer recommendation: https://stackoverflow.com/a/35165401/78935

you can't animate every property,

here's a reference to which are the animatable properties

visibility is animatable while display isn't...

in your case you could also animate opacity or height depending of the kind of effect you want to render_

fiddle with opacity animation

You need to use CreateProcess [ http://msdn.microsoft.com/en-us/library/windows/desktop/ms682425(v=vs.85).aspx ]

For ex:

LPTSTR szCmdline[] = _tcsdup(TEXT("\"C:\Program Files\MyApp\" -L -S")); CreateProcess(NULL, szCmdline, /.../);

To delete all files and directories within the current directory:

find . -mtime +3 | xargs rm -Rf

Or alternatively, more in line with the OP's original command:

find . -mtime +3 -exec rm -Rf -- {} \;

The method show() must be called from the User-Interface (UI) thread, while doInBackground() runs on different thread which is the main reason why AsyncTask was designed.

You have to call show() either in onProgressUpdate() or in onPostExecute().

For example:

class ExampleTask extends AsyncTask<String, String, String> {

    // Your onPreExecute method.

    @Override
    protected String doInBackground(String... params) {
        // Your code.
        if (condition_is_true) {
            this.publishProgress("Show the dialog");
        }
        return "Result";
    }

    @Override
    protected void onProgressUpdate(String... values) {
        super.onProgressUpdate(values);
        connectionProgressDialog.dismiss();
        downloadSpinnerProgressDialog.show();
    }
}

All you have to do is to delete the "0" in the cells that contain just that and try again. That should work.

Try

ROLLBACK WORK;

It usually works

You may use this to access a specific folder and get particular image

 public void Retrieve(String path, String Name)
   {
    File imageFile = new File(path+Name);

    if(imageFile.exists()){

        Bitmap myBitmap = BitmapFactory.decodeFile(path+Name);
        myImage = (ImageView) findViewById(R.id.savedImage);
        myImage.setImageBitmap(myBitmap);
        Toast.makeText(SaveImage.this, myBitmap.toString(), Toast.LENGTH_LONG).show();

    }
}

And then you can call it by

Retrieve(Environment.getExternalStorageDirectory().toString()+"/Aqeel/Images/","Image2.PNG");
Toast.makeText(SaveImage.this, "Saved", Toast.LENGTH_LONG).show();

I find until very useful with sleep. example:

> time = Time.now
> sleep 2.seconds until Time.now > time + 10.seconds # breaks when true
# or something like
> sleep 1.seconds until !req.loading # suggested by ohsully

You can also do it without the [xml] cast. (Although xpath is a world unto itself. https://www.w3schools.com/xml/xml_xpath.asp)

$xml = (select-xml -xpath / -path stack.xml).node
$xml.objects.object.property

Or just this, xpath is case sensitive. Both have the same output:

$xml = (select-xml -xpath /Objects/Object/Property -path stack.xml).node
$xml


Name         Type                                                #text

What you are trying to achieve is equivalent to

interface Event {
   name: string;
   dateCreated: string;
   type: string;
}

interface UserEvent extends Event {
   UserId: string; 
}

The way you defined the types does not allow for specifying inheritance, however you can achieve something similar using intersection types, as artem pointed out.

As stated above to define a map as constant is not possible. But you can declare a global variable which is a struct that contains a map.

The Initialization would look like this:

var romanNumeralDict = struct {
    m map[int]string
}{m: map[int]string {
    1000: "M",
    900: "CM",
    //YOUR VALUES HERE
}}

func main() {
    d := 1000
    fmt.Printf("Value of Key (%d): %s", d, romanNumeralDict.m[1000])
}

PrincipalContext for browsing the AD is ridiculously slow (only use it for .ValidateCredentials, see below), use DirectoryEntry instead and .PropertiesToLoad() so you only pay for what you need.

Filters and syntax here: https://social.technet.microsoft.com/wiki/contents/articles/5392.active-directory-ldap-syntax-filters.aspx

Attributes here: https://docs.microsoft.com/en-us/windows/win32/adschema/attributes-all

using (var root = new DirectoryEntry($"LDAP://{Domain}"))
{
    using (var searcher = new DirectorySearcher(root))
    {
        // looking for a specific user
        searcher.Filter = $"(&(objectCategory=person)(objectClass=user)(sAMAccountName={username}))";
        // I only care about what groups the user is a memberOf
        searcher.PropertiesToLoad.Add("memberOf");

        // FYI, non-null results means the user was found
        var results = searcher.FindOne();

        var properties = results?.Properties;
        if (properties?.Contains("memberOf") == true)
        {
            // ... iterate over all the groups the user is a member of
        }
    }
}

Clean, simple, fast. No magic, no half-documented calls to .RefreshCache to grab the tokenGroups or to .Bind or .NativeObject in a try/catch to validate credentials.

For authenticating the user:

using (var context = new PrincipalContext(ContextType.Domain))
{
    return context.ValidateCredentials(username, password);
}

Math.NET's Iridium library provides a fast, regularly updated collection of math-related functions, including the FFT. It's licensed under the LGPL so you are free to use it in commercial products.

You have mentioned Wrong id

alert(document.getElementById("name").value);

if you want to use name attribute then

alert(document.getElementsByName("username")[0].value);

Updates:

input type="text" id="name" name="username"  

id is different from name

An interesting collection library is https://github.com/mgesmundo/smart-collection. Allows you to watch arrays and add views to them as well. Not sure about the performance as I am testing it out myself. Will update this post soon.

This function will make sure that a file is loaded after the dependency file is loaded completely. You just need to provide the files in a sequence keeping in mind the dependencies on other files.

function loadFiles(files, fn) {
    if (!files.length) {
        files = [];
    }
    var head = document.head || document.getElementsByTagName('head')[0];

    function loadFile(index) {
        if (files.length > index) {
            var fileref = document.createElement('script');
            fileref.setAttribute("type", "text/javascript");
            fileref.setAttribute("src", files[index]);
            head.appendChild(fileref);
            index = index + 1;
            // Used to call a callback function
            fileref.onload = function () {
                loadFile(index);
            }
        } else if(fn){
            fn();
        }
    }
    loadFile(0);
}

My preference is to multiline the args, this is simplest and easiest to read. Also, the script can be changed without affecting the image, just need to restart the pod. For example, for a mysql dump, the container spec could be something like this:

containers:
  - name: mysqldump
    image: mysql
    command: ["/bin/sh", "-c"]
    args:
      - echo starting;
        ls -la /backups;
        mysqldump --host=... -r /backups/file.sql db_name;
        ls -la /backups;
        echo done;
    volumeMounts:
      - ...

The reason this works is that yaml actually concatenates all the lines after the "-" into one, and sh runs one long string "echo starting; ls... ; echo done;".

You cannot prevent people from copying text from your page. If you are trying to satisfy a "requirement" this may work for you:

How to disable Ctrl C/V using javascript for both internet explorer and firefox browsers

A more advanced aproach:

How to detect Ctrl+V, Ctrl+C using JavaScript?

Edit: I just want to emphasise that disabling copy/paste is annoying, won't prevent copying and is 99% likely a bad idea.

It looks like ng-attr is a new directive in AngularJS 1.1.4 that you can possibly use in this case.

<!-- example -->
<a ng-attr-title="{{product.shortDesc}}"></a>

However, if you stay with 1.0.7, you can probably write a custom directive to mirror the effect.

• You can use pandas.Series.astype

• You can do something like this :

  weather["Temp"] = weather.Temp.astype(float)
  

• You can also use pd.to_numeric that will convert the column from object to float

• For details on how to use it checkout this link :http://pandas.pydata.org/pandas-docs/version/0.20/generated/pandas.to_numeric.html

• Example :

  s = pd.Series(['apple', '1.0', '2', -3])
  print(pd.to_numeric(s, errors='ignore'))
  print("=========================")
  print(pd.to_numeric(s, errors='coerce'))
  

• Output:

  0    apple
  1      1.0
  2        2
  3       -3
  =========================
  dtype: object
  0    NaN
  1    1.0
  2    2.0
  3   -3.0
  dtype: float64
  

• In your case you can do something like this:

  weather["Temp"] = pd.to_numeric(weather.Temp, errors='coerce')
  

• Other option is to use convert_objects

• Example is as follows

  >> pd.Series([1,2,3,4,'.']).convert_objects(convert_numeric=True)
  
  0     1
  1     2
  2     3
  3     4
  4   NaN
  dtype: float64
  

• You can use this as follows:

  weather["Temp"] = weather.Temp.convert_objects(convert_numeric=True)
  

• I have showed you examples because if any of your column won't have a number then it will be converted to NaN... so be careful while using it.

Update:

The question doesn't ask for jquery. So lets do it without jquery:

document.addEventListener("DOMContentLoaded", function(event) { 
    //Do work
});

Note this method will not work on IE8.

Old Answer:

You are calling this script before DOM is ready. If you write this code into jquery's $(function() method it will work.

Within Nano use Ctrl+O to save and Ctrl+X to exit if you were wondering

Not an answer to the original question, but an example to the how-to-make-reusable and working custom renderers without breaking MVC :-)

// WRONG
public class DataWrapper {
   final Data data;
   final String description;
   public DataWrapper(Object data, String description) {
       this.data = data;
       this.description = description;
   }
   ....
   @Override
   public String toString() {
       return description;
   } 
}
// usage
myModel.add(new DataWrapper(data1, data1.getName());

It is wrong in a MVC environment, because it is mixing data and view: now the model doesn't contain the data but a wrapper which is introduced for view reasons. That's breaking separation of concerns and encapsulation (every class interacting with the model needs to be aware of the wrapped data).

The driving forces for breaking of rules were:

• keep functionality of the default KeySelectionManager (which is broken by a custom renderer)
• reuse of the wrapper class (can be applied to any data type)

As in Swing a custom renderer is the small coin designed to accomodate for custom visual representation, a default manager which can't cope is ... broken. Tweaking design just to accommodate for such a crappy default is the wrong way round, kind of upside-down. The correct is, to implement a coping manager.

While re-use is fine, doing so at the price of breaking the basic architecture is not a good bargin.

We have a problem in the presentation realm, let's solve it in the presentation realm with the elements designed to solve exactly that problem. As you might have guessed, SwingX already has such a solution :-)

In SwingX, the provider of a string representation is called StringValue, and all default renderers take such a StringValue to configure themselves:

StringValue sv = new StringValue() {
     @Override
     public String getString(Object value) {
        if (value instanceof Data) {
            return ((Data) value).getSomeProperty();
        }
        return TO_STRING.getString(value);
     }
};
DefaultListRenderer renderer = new DefaultListRenderer(sv);

As the defaultRenderer is-a StringValue (implemented to delegate to the given), a well-behaved implementation of KeySelectionManager now can delegate to the renderer to find the appropriate item:

public BetterKeySelectionManager implements KeySelectionManager {

     @Override
     public int selectionForKey(char ch, ComboBoxModel model) {

         ....
         if (getCellRenderer() instance of StringValue) {
              String text = ((StringValue) getCellRenderer()).getString(model.getElementAt(row));
              ....
         } 
     }

}

Outlined the approach because it is easily implementable even without using SwingX, simply define implement something similar and use it:

• some provider of a string representation
• a custom renderer which is configurable by that provider and guarantees to use it in configuring itself
• a well-behaved keySelectionManager with queries the renderer for its string represention

All except the string provider is reusable as-is (that is exactly one implemenation of the custom renderer and the keySelectionManager). There can be general implementations of the string provider, f.i. those formatting value or using bean properties via reflection. And all without breaking basic rules :-)

Just use That.Its Easy.

<script language="javascript" type="text/javascript">
     var images = new Array()
     images[0] = "img1.jpg";
     images[1] = "img2.jpg";
     images[2] = "img3.jpg";
     setInterval("changeImage()", 30000);
     var x=0;

     function changeImage()
     {
                document.getElementById("img").src=images[x]
                x++;
                if (images.length == x) 
                {
                    x = 0;
                }
     }
</script>

And in Body Write this Code:-

<img id="img" src="imgstart.jpg">

You can also achieve this using a CSS Grids framework, such as YUI Grids or Blue Print CSS. They solve alot of the cross browser issues and make more sophisticated column layouts possible for use mere mortals.

getdate() 

is the direct equivalent, but you should always use UTC datetimes

getutcdate()

whether your app operates across timezones or not - otherwise you run the risk of screwing up date math at the spring/fall transitions

Beware of the use of push method, if you don't use indexes, it won't work!

var main2dArray: Things[][] = []

main2dArray.push(someTmp1dArray)
main2dArray.push(someOtherTmp1dArray)

gives only a 1 line array!

use

main2dArray[0] = someTmp1dArray
main2dArray[1] = someOtherTmp1dArray

to get your 2d array working!!!

Other beware! foreach doesn't seem to work with 2d arrays!

You can combine strings using stream string like that:

#include <iostream>
#include <sstream>
using namespace std;
int main()
{
    string name = "Bill";
    stringstream ss;
    ss << "Your name is: " << name;
    string info = ss.str();
    cout << info << endl;
    return 0;
}

$(".thumbs").hover(
    function(){
        if (!$(this).hasClass("selected")) {
            $(this).stop().fadeTo("normal", 1.0);
        }
    },
    function(){
        if (!$(this).hasClass("selected")) {
            $(this).stop().fadeTo("slow", 0.3); 
        }           
    }
);

Putting an if inside of each part of the hover will allow you to change the select class dynamically and the hover will still work.

$(".thumbs").click(function() {
    $(".thumbs").each(function () {
        if ($(this).hasClass("selected")) {
            $(this).removeClass("selected");
            $(this).hover();
        }
    });                 
    $(this).addClass("selected");                   
});

As an example I've also attached a click handler to switch the selected class to the clicked item. Then I fire the hover event on the previous item to make it fade out.

In Spring 3.0 you can make your bean implement BeanDefinitionRegistryPostProcessor and add new beans via BeanDefinitionRegistry.

In previous versions of Spring you can do the same thing in BeanFactoryPostProcessor (though you need to cast BeanFactory to BeanDefinitionRegistry, which may fail).

Keep in mind that 0x80 = 80h = 128

You can see here that INT is just one of the many instructions (actually the Assembly Language representation (or should I say 'mnemonic') of it) that exists in the x86 instruction set. You can also find more information about this instruction in Intel's own manual found here.

To summarize from the PDF:

INT n/INTO/INT 3—Call to Interrupt Procedure

The INT n instruction generates a call to the interrupt or exception handler specified with the destination operand. The destination operand specifies a vector from 0 to 255, encoded as an 8-bit unsigned intermediate value. The INT n instruction is the general mnemonic for executing a software-generated call to an interrupt handler.

As you can see 0x80 is the destination operand in your question. At this point the CPU knows that it should execute some code that resides in the Kernel, but what code? That is determined by the Interrupt Vector in Linux.

One of the most useful DOS software interrupts was interrupt 0x21. By calling it with different parameters in the registers (mostly ah and al) you could access various IO operations, string output and more.

Most Unix systems and derivatives do not use software interrupts, with the exception of interrupt 0x80, used to make system calls. This is accomplished by entering a 32-bit value corresponding to a kernel function into the EAX register of the processor and then executing INT 0x80.

Take a look at this please where other available values in the interrupt handler tables are shown:

As you can see the table points the CPU to execute a system call. You can find the Linux System Call table here.

So by moving the value 0x1 to EAX register and calling the INT 0x80 in your program, you can make the process go execute the code in Kernel which will stop (exit) the current running process (on Linux, x86 Intel CPU).

A hardware interrupt must not be confused with a software interrupt. Here is a very good answer on this regard.

This also is good source.

If you're looking to change the title text size and the text color you have to change the NSDictionary titleTextAttributes, for 2 of its objects:

    self.navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"Arial" size:13.0],NSFontAttributeName,
                                                                  [UIColor whiteColor], NSForegroundColorAttributeName, 
                                                                  nil];

The easiest, if verbose way to do this is to wrap each number in a Math.abs() call, so you would add:

Math.abs(1) + Math.abs(2) + Math.abs(1) + Math.abs(-1)

with logic changes to reflect how your code is structured. Verbose, perhaps, but it does what you want.

As said above, in general you should not rely on the hash code of a class remaining the same. Note that even subsequent runs of the same application on the same VM may produce different hash values. AFAIK the Sun JVM's hash function calculates the same hash on every run, but that's not guaranteed.

Note that this is not theoretical. The hash function for java.lang.String was changed in JDK1.2 (the old hash had problems with hierarchical strings like URLs or file names, as it tended to produce the same hash for strings which only differed at the end).

java.lang.String is a special case, as the algorithm of its hashCode() is (now) documented, so you can probably rely on that. I'd still consider it bad practice. If you need a hash algorithm with special, documented properties, just write one :-).

this works for me, so try it :

Microsoft.Office.Interop.Excel.Range rng =(Microsoft.Office.Interop.Excel.Range)XcelApp.Cells[1, i];
rng.Font.Bold = true; 
rng.Interior.Color =System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Yellow);
rng.BorderAround(); 

1. Use conditional formatting instead of VBA to highlight errors.

2. Using a VBA loop like the one you posted will take a long time to process

3. the statement If cell.Value = "#N/A" Then will never work. If you insist on using VBA to highlight errors, try this instead.

   Sub ColorCells()

   Dim Data As Range
   Dim cell As Range
   Set currentsheet = ActiveWorkbook.Sheets("Comparison")
   Set Data = currentsheet.Range("A2:AW1048576")
   
   For Each cell In Data
   
   If IsError(cell.Value) Then
      cell.Interior.ColorIndex = 3
   End If
   Next
   
   End Sub
   

4. Be prepared for a long wait, since the procedure loops through 51 million cells

5. There are more efficient ways to achieve what you want to do. Update your question if you have a change of mind.

Look here:

http://web.archive.org/web/20170106202838/https://it.cornell.edu/services/managed_servers/howto/file_transfer/fileputty.cfm#puttytrans

It recommends using pscp.exe from PuTTY, which can be found here: https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

A direct transfer like FTP is not possible, because all commands during your session are send to the server.

I think you achieve with change and keyUp event.

I used Matchers.refEq for this.

I tried a couple of solution but I thing easy way like this (you are in the local folder):

#!/bin/bash
git fetch

var_local=`cat .git/refs/heads/master`
var_remote=`git log origin/master -1 | head -n1 | cut -d" " -f2`

if [ "$var_remote" = "$var_local" ]; then
    echo "Strings are equal." #1
else
    echo "Strings are not equal." #0 if you want
fi

Then you did compare local git and remote git last commit number....

How about this one.

Windows 10 and Android Studio: Ctrl + / (on small num pad), don't use Ctrl + Shift-7!

You can access the form over the event:

e.target.reset();

This is the hardware serial number. To access it on

• Android Q (>= SDK 29) android.Manifest.permission.READ_PRIVILEGED_PHONE_STATE is required. Only system apps can require this permission. If the calling package is the device or profile owner then the READ_PHONE_STATE permission suffices.

• Android 8 and later (>= SDK 26) use android.os.Build.getSerial() which requires the dangerous permission READ_PHONE_STATE. Using android.os.Build.SERIAL returns android.os.Build.UNKNOWN.

• Android 7.1 and earlier (<= SDK 25) and earlier android.os.Build.SERIAL does return a valid serial.

It's unique for any device. If you are looking for possibilities on how to get/use a unique device id you should read here.

For a solution involving reflection without requiring a permission see this answer.

For linux users: possible solution.

Build error due to "Failed to delete < any-file-or-folder >" will occur if there is by chance of only delete access provided to root user rather to normal-user.

Fix : type ll command to list file that cannot be deleted, if the file is given root access, change to normal user by :

sudo chown -R user-name:user-name filename

Later try for maven clean and build.

As the cause of the error is obvious, here's some information that should help you solve the problem:

See this MS article about Naming Files, Paths, and Namespaces

Here's a quote from the link:

Maximum Path Length Limitation In the Windows API (with some exceptions discussed in the following paragraphs), the maximum length for a path is MAX_PATH, which is defined as 260 characters. A local path is structured in the following order: drive letter, colon, backslash, name components separated by backslashes, and a terminating null character. For example, the maximum path on drive D is "D:\some 256-character path string<NUL>" where "<NUL>" represents the invisible terminating null character for the current system codepage. (The characters < > are used here for visual clarity and cannot be part of a valid path string.)

And a few workarounds (taken from the comments):

There are ways to solve the various problems. The basic idea of the solutions listed below is always the same: Reduce the path-length in order to have path-length + name-length < MAX_PATH. You may:

• Share a subfolder
• Use the commandline to assign a drive letter by means of SUBST
• Use AddConnection under VB to assign a drive letter to a path

If you have

<div>
  <input type="checkbox" class="check-with-label" id="idinput" />
  <label class="label-for-check" for="idinput">My Label</label>
</div>

you can do

.check-with-label:checked + .label-for-check {
  font-weight: bold;
}

See this working. Note that this won't work in non-modern browsers.

try:

var url = '/Home/Index/' + e.value;
 window.location = window.location.host + url; 

That should get you where you want.

Since you have a star-schema design, you might want to structure it more like a relational table and less like a dictionary.

import collections

class Jobs( object ):
    def __init__( self, state, county, title, count ):
        self.state= state
        self.count= county
        self.title= title
        self.count= count

facts = [
    Jobs( 'new jersey', 'mercer county', 'plumbers', 3 ),
    ...

def groupBy( facts, name ):
    total= collections.defaultdict( int )
    for f in facts:
        key= getattr( f, name )
        total[key] += f.count

That kind of thing can go a long way to creating a data warehouse-like design without the SQL overheads.

React Native Dimensions is only a partial answer to this question, I came here looking for the actual pixel size of the screen, and the Dimensions actually gives you density independent layout size.

You can use React Native Pixel Ratio to get the actual pixel size of the screen.

You need the import statement for both Dimenions and PixelRatio

import { Dimensions, PixelRatio } from 'react-native';

You can use object destructuring to create width and height globals or put it in stylesheets as others suggest, but beware this won't update on device reorientation.

const { width, height } = Dimensions.get('window');

From React Native Dimension Docs:

Note: Although dimensions are available immediately, they may change (e.g due to >device rotation) so any rendering logic or styles that depend on these constants >should try to call this function on every render, rather than caching the value >(for example, using inline styles rather than setting a value in a StyleSheet).

PixelRatio Docs link for those who are curious, but not much more there.

To actually get the screen size use:

PixelRatio.getPixelSizeForLayoutSize(width);

or if you don't want width and height to be globals you can use it anywhere like this

PixelRatio.getPixelSizeForLayoutSize(Dimensions.get('window').width);

I am using Spyder (Python 2.7) and to clean the interpreter console I use either

Sendmail wasn't working for me so I used msmtp 1.6.2 w32 and most just followed the instructions at DeveloperSide. Here is a quick rundown of the setup for posterity:

Enabled IMAP access under your Gmail account (the one msmtp is sending emails from)

Enable access for less secure apps. Log into your google account and go here

Edit php.ini, find and change each setting below to reflect the following:

; These are commented out by prefixing a semicolon
;SMTP = localhost
;smtp_port = 25

; Set these paths to where you put your msmtp files.
; I used backslashes in php.ini and it works fine.
; The example in the devside guide uses forwardslashes. 
sendmail_path = "C:\wamp64\msmtp\msmtp.exe -d -C C:\wamp64\msmtp\msmtprc.ini -t --read-envelope-from"

mail.log = "C:\wamp64\msmtp\maillog.txt"

Create and edit the file msmtprc.ini in the same directory as your msmtp.exe file as follows, replacing it with your own email and password:

# Default values for all accounts
defaults
tls_certcheck off
# I used forward slashes here and it works.
logfile C:/wamp64/msmtp/msmtplog.txt

account Gmail
host smtp.gmail.com
port 587
auth on
tls on
from [email protected]
user [email protected]
password ReplaceWithYourPassword
account default : gmail

Create a Keybinding

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

Preferences > Key Bindings - users

And adding this code between the square brackets

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

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

Source here

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

@extend .myclass;
@extend #{'.my-class'};

You can do it like this (with a slightly modified array to show it works for non-square arrays):

        long[,] arr = new long[5, 4] { { 1, 2, 3, 4 }, { 1, 1, 1, 1 }, { 2, 2, 2, 2 }, { 3, 3, 3, 3 }, { 4, 4, 4, 4 } };

        int rowLength = arr.GetLength(0);
        int colLength = arr.GetLength(1);

        for (int i = 0; i < rowLength; i++)
        {
            for (int j = 0; j < colLength; j++)
            {
                Console.Write(string.Format("{0} ", arr[i, j]));
            }
            Console.Write(Environment.NewLine + Environment.NewLine);
        }
        Console.ReadLine();

on ubuntu print packages related to an executable

ldd executable_name|awk '{print $3}'|xargs dpkg -S |awk -F  ":"  '{print $1}'

The following works as of now (tested in chrome and firefox):

<form onsubmit="event.preventDefault(); return validateMyForm();">

where validateMyForm() is a function that returns false if validation fails. The key point is to use the name event. We cannot use for e.g. e.preventDefault()

Try to give it a postion: absolute;

For my part, and without any plug-in, simply saving the file either from the File menu or with keyboards shortcuts

CTRL + S (Windows, Linux) or CMD + S (Mac OS)

briefly displays the current encoding - between parentheses - in the status bar, at the bottom of the editor's window. This suggestion works in Sublime Text 2 and 3.

Note that the displayed encoding to the right in the status bar of Sublime Text 3, may display the wrong encoding of the file if you have attempted to save the file with an encoding that can't represent all the characters in your file. In this case you would have seen an informational dialog and Sublime telling you it's falling back to UTF-8. This may not be the case, so be careful.

Or you can make a simple function like this:

// Provided 'c' is only a numeric character
int parseInt (char c) {
    return c - '0';
}

I think what you have missed here is this:

https://maven.apache.org/settings.html#Servers

The repositories for download and deployment are defined by the repositories and distributionManagement elements of the POM. However, certain settings such as username and password should not be distributed along with the pom.xml. This type of information should exist on the build server in the settings.xml.

This is the prefered way of using custom repos. So probably what is happening is that the url of this repo is in settings.xml of the build server.

Once you get hold of the url and credentials, you can put them in your machine here: ~/.m2/settings.xml like this:

<settings ...> 

        .
        .
        .
        <servers>
            <server>
              <id>internal-repository-group</id>
              <username>YOUR-USERNAME-HERE</username>
              <password>YOUR-PASSWORD-HERE</password>
            </server>
        </servers>
</settings>

EDIT:

You then need to refer this repository into project POM. The id internal-repository-group can be used in every project. You can setup multiple repos and credentials setting using different IDs in settings xml.

The advantage of this approach is that project can be shared without worrying about the credentials and don't have to mention the credentials in every project.

Following is a sample pom of a project using "internal-repository-group"

<repositories>
    <repository>
        <id>internal-repository-group</id>
        <name>repo-name</name>
        <url>http://project.com/yourrepourl/</url>
        <layout>default</layout>
        <releases>
            <enabled>true</enabled>
            <updatePolicy>never</updatePolicy>

        <snapshots>
            <enabled>true</enabled>

Ensure that the permissions on your home directory and on the home directory of the user on the host you're connecting to are set to 700 ( owning user rwx only to prevent others seeing the .ssh subdirectory ).

Then ensure that the ~/.ssh directory is also 700 ( user rwx ) and that the authorized_keys is 600 ( user rw ) .

Private keys in your ~/.ssh directory should be 600 or 400 ( user rw or user r )

You can also configure m2e to use HTTP instead of HTTPS

You certainly want to hack the header to have a proper Ajax Request :

headers = {'X_REQUESTED_WITH' :'XMLHttpRequest',
           'ACCEPT': 'application/json, text/javascript, */*; q=0.01',}
request = urllib2.Request(path, data, headers)
response = urllib2.urlopen(request).read()

And to json.loads the POST on the server-side.

Edit : By the way, you have to urllib.urlencode(mydata_dict) before sending them. If you don't, the POST won't be what the server expect

How is it not compatible with C#? Boolean.Parse and Boolean.TryParse is case insensitive and the parsing is done by comparing the value to Boolean.TrueString or Boolean.FalseString which are "True" and "False".

EDIT: When looking at the Boolean.ToString method in reflector it turns out that the strings are hard coded so the ToString method is as follows:

public override string ToString()
{
    if (!this)
    {
        return "False";
    }
    return "True";
}

If order matters, you should keep a property on the "T" objects in your list that denotes sequence. In order to swap them, just swap the value of that property, and then use that in the .Sort(comparison with sequence property)

small update for swift 5:

let refreshAlert = UIAlertController(title: "Refresh", message: "All data will be lost.", preferredStyle: UIAlertController.Style.alert)

    refreshAlert.addAction(UIAlertAction(title: "Ok", style: .default, handler: { (action: UIAlertAction!) in
          print("Handle Ok logic here")
    }))

    refreshAlert.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: { (action: UIAlertAction!) in
          print("Handle Cancel Logic here")
    }))

    self.present(refreshAlert, animated: true, completion: nil)

Try this:

[(i, j) for i, j in enumerate(mylist)]

You need to put i,j inside a tuple for the list comprehension to work. Alternatively, given that enumerate() already returns a tuple, you can return it directly without unpacking it first:

[pair for pair in enumerate(mylist)]

Either way, the result that gets returned is as expected:

> [(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd')]

Here is a solution using observables.

waitForElementToAppear(elementId) {                                          

    return Observable.create(function(observer) {                            
            var el_ref;                                                      
            var f = () => {                                                  
                el_ref = document.getElementById(elementId);                 
                if (el_ref) {                                                
                    observer.next(el_ref);                                   
                    observer.complete();                                     
                    return;                                                  
                }                                                            
                window.requestAnimationFrame(f);                             
            };                                                               
            f();                                                             
        });                                                                  
}                                                                            

Now you can write

waitForElementToAppear(elementId).subscribe(el_ref => doSomethingWith(el_ref);

In addition to Gilson PJ answer:

 new webpack.optimize.CommonsChunkPlugin('common.js'),
 new webpack.optimize.DedupePlugin(),
 new webpack.optimize.UglifyJsPlugin(),
 new webpack.optimize.AggressiveMergingPlugin()

with

"scripts": {
    "build": "NODE_ENV=production webpack -p --config ./webpack.production.config.js"
},

cause that the it tries to uglify your code twice. See https://webpack.github.io/docs/cli.html#production-shortcut-p for more information.

You can fix this by removing the UglifyJsPlugin from plugins-array or add the OccurrenceOrderPlugin and remove the "-p"-flag. so one possible solution would be

 new webpack.optimize.CommonsChunkPlugin('common.js'),
 new webpack.optimize.DedupePlugin(),
 new webpack.optimize.UglifyJsPlugin(),
 new webpack.optimize.OccurrenceOrderPlugin(),
 new webpack.optimize.AggressiveMergingPlugin()

and

"scripts": {
    "build": "NODE_ENV=production webpack --config ./webpack.production.config.js"
},

You don't need the jsp:useBean to set the model if you already have a controller which prepared the model.

Just access it plain by EL:

<p>${Questions.questionPaperID}</p>
<p>${Questions.question}</p>

or by JSTL <c:out> tag if you'd like to HTML-escape the values or when you're still working on legacy Servlet 2.3 containers or older when EL wasn't supported in template text yet:

<p><c:out value="${Questions.questionPaperID}" /></p>
<p><c:out value="${Questions.question}" /></p>

See also:

• Our Servlets wiki page

Unrelated to the problem, the normal practice is by the way to start attribute name with a lowercase, like you do with normal variable names.

session.setAttribute("questions", questions);

and alter EL accordingly to use ${questions}.

Also note that you don't have any JSTL tag in your code. It's all plain JSP.

If you use C/C++, there's no "range" syntax. You can only list all values after each "case" segment. Language Ada or Pascal support range syntax.

I add a picture, show configdifference between mirror and bare. The left is bare, right is mirror. You can be clear, mirror's config file have fetch key, which means you can update it,by git remote update or git fetch --all

Simple and effective approach is models.py

The solution of Jack Giffin is great but doesn't work for arrays with numbers bigger than 2^32. Below is a refactored, fast version to filter an array based on Jack's solution but it works for 64-bit arrays.

const Math_clz32 = Math.clz32 || ((log, LN2) => x => 31 - log(x >>> 0) / LN2 | 0)(Math.log, Math.LN2);

const filterArrayByAnotherArray = (searchArray, filterArray) => {

    searchArray.sort((a,b) => a > b);
    filterArray.sort((a,b) => a > b);

    let searchArrayLen = searchArray.length, filterArrayLen = filterArray.length;
    let progressiveLinearComplexity = ((searchArrayLen<<1) + filterArrayLen)>>>0
    let binarySearchComplexity = (searchArrayLen * (32-Math_clz32(filterArrayLen-1)))>>>0;

    let i = 0;

    if (progressiveLinearComplexity < binarySearchComplexity) {
      return searchArray.filter(currentValue => {
        while (filterArray[i] < currentValue) i=i+1|0;
        return filterArray[i] !== currentValue;
      });
    }
    else return searchArray.filter(e => binarySearch(filterArray, e) === null);
}

const binarySearch = (sortedArray, elToFind) => {
  let lowIndex = 0;
  let highIndex = sortedArray.length - 1;
  while (lowIndex <= highIndex) {
    let midIndex = Math.floor((lowIndex + highIndex) / 2);
    if (sortedArray[midIndex] == elToFind) return midIndex; 
    else if (sortedArray[midIndex] < elToFind) lowIndex = midIndex + 1;
    else highIndex = midIndex - 1;
  } return null;
}

You shoudn't use app.use(express.bodyParser()). BodyParser is a union of json + urlencoded + mulitpart. You shoudn't use this because multipart will be removed in connect 3.0.

To resolve that, you can do this:

app.use(express.json());
app.use(express.urlencoded());

It´s very important know that app.use(app.router) should be used after the json and urlencoded, otherwise it does not work!

First I would suggest putting a Log in each case of your switch to be sure that your code is being called.

Then I would check that the layouts are actually different.

Instead of telling you how you could execute a certain command (Esc:wq), I can provide you two links that may help you with VIM:

• http://bullium.com/support/vim.html provides an HTML quick reference card
• http://tnerual.eriogerg.free.fr/vim.html provides a PDF quick reference card in several languages, optimized for print-out, fold and put on your desk drawer

However, the best way to learn Vim is not only using it for Git commits, but as a regular editor for your everyday work.

If you're not going to switch to Vim, it's nonsense to keep its commands in mind. In that case, go and set up your favourite editor to use with Git.

I test this code and

$db=new PDO('mysql:host=localhost;dbname=cwDB','root','',
array(PDO::MYSQL_ATTR_INIT_COMMAND => "SET NAMES utf8"));
$sql="select * from products  ";
$stmt=$db->prepare($sql);
$stmt->execute();
while($result=$stmt->fetch(PDO::FETCH_ASSOC)){                  
    $id=$result['id'];
}

Something to consider

.isDisplayed() assumes the element is present (exists in the DOM)

so if you do

expect($('[ng-show=saving]').isDisplayed()).toBe(true);

but the element is not present, then instead of graceful failed expectation, $('[ng-show=saving]').isDisplayed() will throw an error causing the rest of it block not executed

Solution

If you assume, the element you're checking may not be present for any reason on the page, then go with a safe way below

/**
*  element is Present and is Displayed
*  @param    {ElementFinder}      $element       Locator of element
*  @return   {boolean}
*/
let isDisplayed = function ($element) {
  return (await $element.isPresent()) && (await $element.isDisplayed())
}

and use

expect(await isDisplayed( $('[ng-show=saving]') )).toBe(true);

Lines 1,2,3,4 will call the default constructor. They are different in the essence as 1,2 are dynamically created object and 3,4 are statically created objects.

In Line 7, you create an object inside the argument call. So its an error.

And Lines 5 and 6 are invitation for memory leak.

It seems more pythonic to use a for loop. See the quote from What’s New In Python 3.0.

Removed reduce(). Use functools.reduce() if you really need it; however, 99 percent of the time an explicit for loop is more readable.

def nested_get(dic, keys):    
    for key in keys:
        dic = dic[key]
    return dic

Note that the accepted solution doesn't set non-existing nested keys (it raises KeyError). Using the approach below will create non-existing nodes instead:

def nested_set(dic, keys, value):
    for key in keys[:-1]:
        dic = dic.setdefault(key, {})
    dic[keys[-1]] = value

The code works in both Python 2 and 3.

The commandline interpreter does indeed have a FOR construct that you can use from the command prompt or from within a batch file.

For your purpose, you probably want something like:

FOR %i IN (*.ext) DO my-function %i

Which will result in the name of each file with extension *.ext in the current directory being passed to my-function (which could, for example, be another .bat file).

The (*.ext) part is the "filespec", and is pretty flexible with how you specify sets of files. For example, you could do:

FOR %i IN (C:\Some\Other\Dir\*.ext) DO my-function %i

To perform an operation in a different directory.

There are scores of options for the filespec and FOR in general. See

HELP FOR

from the command prompt for more information.

Use smaller h

// 24 hrs 
H:i 
// output 14:20

// 12 hrs 
h:i 
// output 2:20

you can use .NET's built in method to remove the QueryString. i.e., Request.QueryString.Remove["whatever"];

here whatever in the [ ] is name of the querystring which you want to remove.

Try this... I hope this will help.

To perform this operation see the next images:

and next step is add *.mdf file,

very important, the .mdf file must be located in C:......\MSSQL12.SQLEXPRESS\MSSQL\DATA

Now remove the log file

In static class, if you are getting information from xml or reg, class tries to initialize all properties. therefore, you should control if the config variable is there otherwise properties will not initialize so the class.

Check xml referance variable is there, Check reg referance variable is is there, Make sure you handle if they are not there.

Cloning the objects before adding them. For example, instead of newList.addAll(oldList);

for(Person p : oldList) {
    newList.add(p.clone());
}

Assuming clone is correctly overriden inPerson.

This works fine

<?php
      $con=mysqli_connect("localhost","my_user","my_password","my_db");
      $con->query("SET GLOBAL time_zone = 'Asia/Calcutta'");
      $con->query("SET time_zone = '+05:30'");
      $con->query("SET @@session.time_zone = '+05:30'");
?>

The problem with all the approaches based on gethostbyname is that you will not get all IP addresses assigned to a particular machine. Servers usually have more than one adapter.

Here is an example of how you can iterate through all Ipv4 and Ipv6 addresses on the host machine:

void ListIpAddresses(IpAddresses& ipAddrs)
{
  IP_ADAPTER_ADDRESSES* adapter_addresses(NULL);
  IP_ADAPTER_ADDRESSES* adapter(NULL);

  // Start with a 16 KB buffer and resize if needed -
  // multiple attempts in case interfaces change while
  // we are in the middle of querying them.
  DWORD adapter_addresses_buffer_size = 16 * KB;
  for (int attempts = 0; attempts != 3; ++attempts)
  {
    adapter_addresses = (IP_ADAPTER_ADDRESSES*)malloc(adapter_addresses_buffer_size);
    assert(adapter_addresses);

    DWORD error = ::GetAdaptersAddresses(
      AF_UNSPEC, 
      GAA_FLAG_SKIP_ANYCAST | 
        GAA_FLAG_SKIP_MULTICAST | 
        GAA_FLAG_SKIP_DNS_SERVER |
        GAA_FLAG_SKIP_FRIENDLY_NAME, 
      NULL, 
      adapter_addresses,
      &adapter_addresses_buffer_size);

    if (ERROR_SUCCESS == error)
    {
      // We're done here, people!
      break;
    }
    else if (ERROR_BUFFER_OVERFLOW == error)
    {
      // Try again with the new size
      free(adapter_addresses);
      adapter_addresses = NULL;

      continue;
    }
    else
    {
      // Unexpected error code - log and throw
      free(adapter_addresses);
      adapter_addresses = NULL;

      // @todo
      LOG_AND_THROW_HERE();
    }
  }

  // Iterate through all of the adapters
  for (adapter = adapter_addresses; NULL != adapter; adapter = adapter->Next)
  {
    // Skip loopback adapters
    if (IF_TYPE_SOFTWARE_LOOPBACK == adapter->IfType)
    {
      continue;
    }

    // Parse all IPv4 and IPv6 addresses
    for (
      IP_ADAPTER_UNICAST_ADDRESS* address = adapter->FirstUnicastAddress; 
      NULL != address;
      address = address->Next)
    {
      auto family = address->Address.lpSockaddr->sa_family;
      if (AF_INET == family)
      {
        // IPv4
        SOCKADDR_IN* ipv4 = reinterpret_cast<SOCKADDR_IN*>(address->Address.lpSockaddr);

        char str_buffer[INET_ADDRSTRLEN] = {0};
        inet_ntop(AF_INET, &(ipv4->sin_addr), str_buffer, INET_ADDRSTRLEN);
        ipAddrs.mIpv4.push_back(str_buffer);
      }
      else if (AF_INET6 == family)
      {
        // IPv6
        SOCKADDR_IN6* ipv6 = reinterpret_cast<SOCKADDR_IN6*>(address->Address.lpSockaddr);

        char str_buffer[INET6_ADDRSTRLEN] = {0};
        inet_ntop(AF_INET6, &(ipv6->sin6_addr), str_buffer, INET6_ADDRSTRLEN);

        std::string ipv6_str(str_buffer);

        // Detect and skip non-external addresses
        bool is_link_local(false);
        bool is_special_use(false);

        if (0 == ipv6_str.find("fe"))
        {
          char c = ipv6_str[2];
          if (c == '8' || c == '9' || c == 'a' || c == 'b')
          {
            is_link_local = true;
          }
        }
        else if (0 == ipv6_str.find("2001:0:"))
        {
          is_special_use = true;
        }

        if (! (is_link_local || is_special_use))
        {
          ipAddrs.mIpv6.push_back(ipv6_str);
        }
      }
      else
      {
        // Skip all other types of addresses
        continue;
      }
    }
  }

  // Cleanup
  free(adapter_addresses);
  adapter_addresses = NULL;

  // Cheers!
}

I've wrestled with this myself, trying to make it work from the server. Couldn't. Instead...

1. To clarify on @dnc253's answer, $window.open(URL) is a method for having an Angular application open a given URL in another window. (It's really just a testable angular proxy for the universal window.open().) This is a great solution, preserves your history, and gets the file downloaded and possibly renders it in that fresh browser window if that's supported. But it often runs into popup blockers, which is a huge problem for reliability. Users often simply don't understand what's going on with them. So, if you don't mind immediately downloading the file with the current window, you can simply use the equally effective universal javascript method: location.href = "uriString", which works like a charm for me. Angular doesn't even realize anything has happened. I call it in a promise handler for once my POST/PUT operation has completed. If need be, have the POST/PUT return the URL to call, if you can't already infer it. You'll get the same behavior for the user as if it had downloaded in response to the PUT/POST. For example:

   $http.post(url, payload).then(function(returnData){
       var uriString = parseReturn(returnData);
       location.href="uriString"
   })
   

2. You can, in fact, download something directly from an XHR request, but it requires full support for the HTML5 file API and is usually more trouble than it's worth unless you need to perform local transformations upon the file before you make it available to the user. (Sadly, I lack the time to provide details on that but there are other SO posts about using it.)

These configurations worked in January of 2020 on my new machine build:

(1 - x64 only) Windows 10 x64, Office 365 x64, AccessDatabaseEngine_x64 2016 installed with /passive argument, VStudio build settings set to x64 explicitly, with the following connection string: Provider= Microsoft.ACE.OLEDB.16.0; Data Source=D:...\MyDatabase.accdb

(2 - x64 or x32) Windows 10 x64, Office 365 x64, AccessDatabaseEngine_x64 2016 installed with /passive argument, PLUS AccessDatabaseEngine 2010 (32bit) installed with /passive argument, VStudio build settings set to AnyCPU, with the following connection string: Provider= Microsoft.ACE.OLEDB.16.0; Data Source=D:...\MyDatabase.accdb

(3 - x32 only) Windows 10 x64, Office 365 x32, AccessDatabaseEngine 2010 (32bit) installed with /passive argument, VStudio build settings set to x86, with the following connection string: Provider= Microsoft.ACE.OLEDB.12.0; Data Source=D:...\MyDatabase.accdb

FAILURE NOTES

Using the ACE.OLEDB.12.0 x64 provider in the connection string failed with only the AccessDatabaseEngine_x64 2016 installed as above in (1).

Using AnyCPU in the visual studio build settings failed in (1). Setting x64 is required. Maybe this is because AnyCPU means that Vstudio must see an x32 ACE.OLEDB.nn.0 provider at compile time.

The ACE.OLEDB.12.0 2016 x32 /passive engine would NOT install when it saw x64 applications around. (The ACE.OLEDB.12.0 2010 x32 /passive installer worked.)

CONCLUSIONS

To use x64 build settings, you need to have the 2016 x64 database engine AND the ACE.OLEDB.16.0 connection-string provider AND explicit x64 build settings to work with Office 365 in January of 2020. Using the /passive option makes installations easy. Credit to whoever posted that tip!

To use AnyCPU, I needed to have both the ACE.OLEDB.12.0 2010 x32 engine and the ACE.OLEDB.16.0 x64 engines installed. That way Vstudio could see both x32 and x64 engines at "AnyCPU" compile time. I could change the provider connection string to ACE.OLEDB.12.0 for x32 operation or to ACE.OLEDB.16.0 for x64 operation. Both worked fine.

To use x86 build settings, you need to have the 2010 x32 database engine AND the ACE.OLEDB.12.0 connection-string provider AND explicit x86 build settings to work with Office 365 x32 in January of 2020.

From MySQL docs:

A character set is a set of symbols and encodings. A collation is a set of rules for comparing characters in a character set. Let's make the distinction clear with an example of an imaginary character set.

Suppose that we have an alphabet with four letters: 'A', 'B', 'a', 'b'. We give each letter a number: 'A' = 0, 'B' = 1, 'a' = 2, 'b' = 3. The letter 'A' is a symbol, the number 0 is the encoding for 'A', and the combination of all four letters and their encodings is a character set.

Now, suppose that we want to compare two string values, 'A' and 'B'. The simplest way to do this is to look at the encodings: 0 for 'A' and 1 for 'B'. Because 0 is less than 1, we say 'A' is less than 'B'. Now, what we've just done is apply a collation to our character set. The collation is a set of rules (only one rule in this case): "compare the encodings." We call this simplest of all possible collations a binary collation.

But what if we want to say that the lowercase and uppercase letters are equivalent? Then we would have at least two rules: (1) treat the lowercase letters 'a' and 'b' as equivalent to 'A' and 'B'; (2) then compare the encodings. We call this a case-insensitive collation. It's a little more complex than a binary collation.

In real life, most character sets have many characters: not just 'A' and 'B' but whole alphabets, sometimes multiple alphabets or eastern writing systems with thousands of characters, along with many special symbols and punctuation marks. Also in real life, most collations have many rules: not just case insensitivity but also accent insensitivity (an "accent" is a mark attached to a character as in German 'ö') and multiple-character mappings (such as the rule that 'ö' = 'OE' in one of the two German collations).

There's already a question about this, you could perhaps read it

Deep cloning objects

There's no Clone() method as it exists in Java for example, but you could include a copy constructor in your clases, that's another good approach.

class A
{
  private int attr

  public int Attr
  {
     get { return attr; }
     set { attr = value }
  }

  public A()
  {
  }

  public A(A p)
  {
     this.attr = p.Attr;
  }  
}

This would be an example, copying the member 'Attr' when building the new object.

Just use the following method, pass it lat and long and get distance in meter:

private static double distance_in_meter(final double lat1, final double lon1, final double lat2, final double lon2) {
    double R = 6371000f; // Radius of the earth in m
    double dLat = (lat1 - lat2) * Math.PI / 180f;
    double dLon = (lon1 - lon2) * Math.PI / 180f;
    double a = Math.sin(dLat/2) * Math.sin(dLat/2) +
            Math.cos(latlong1.latitude * Math.PI / 180f) * Math.cos(latlong2.latitude * Math.PI / 180f) *
                    Math.sin(dLon/2) * Math.sin(dLon/2);
    double c = 2f * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));
    double d = R * c;
    return d;
}

Besides calling omp_get_num_threads() outside of the parallel region in your case, calling omp_set_num_threads() still doesn't guarantee that the OpenMP runtime will use exactly the specified number of threads. omp_set_num_threads() is used to override the value of the environment variable OMP_NUM_THREADS and they both control the upper limit of the size of the thread team that OpenMP would spawn for all parallel regions (in the case of OMP_NUM_THREADS) or for any consequent parallel region (after a call to omp_set_num_threads()). There is something called dynamic teams that could still pick smaller number of threads if the run-time system deems it more appropriate. You can disable dynamic teams by calling omp_set_dynamic(0) or by setting the environment variable OMP_DYNAMIC to false.

To enforce a given number of threads you should disable dynamic teams and specify the desired number of threads with either omp_set_num_threads():

omp_set_dynamic(0);     // Explicitly disable dynamic teams
omp_set_num_threads(4); // Use 4 threads for all consecutive parallel regions
#pragma omp parallel ...
{
    ... 4 threads used here ...
}

or with the num_threads OpenMP clause:

omp_set_dynamic(0);     // Explicitly disable dynamic teams
// Spawn 4 threads for this parallel region only
#pragma omp parallel ... num_threads(4)
{
    ... 4 threads used here ...
}

The Version 56.0.2924.87 which I am in now, Undocks the DevTools automatically if you are NOT in a desktop. Otherwise Open a NEW new Chrome tab and Inspect to Dock the DevTools back into the window.

Go to http://dev.mysql.com/downloads/connector/j and with in the dropdown select "Platform Independent" then it will show you the options to download tar.gz file or zip file.

Download zip file and extract it, with in that you will find mysql-connector-XXX.jar file

If you are using maven then you can add the dependency from the link http://mvnrepository.com/artifact/mysql/mysql-connector-java

Select the version you want to use and add the dependency in your pom.xml file

When I'm doing something like this I use the onKeyUp event.

<script type="text/javascript">
 function bar() {
      //do stuff
 }
<input type="text" name="foo" onKeyUp="return bar()" />

but if you don't want to use an HTML event you could try to use jQuerys .change() method

$('.target').change(function() {
   //do stuff
});

in this example, the input would have to have a class "target"

if you're going to have multiple text boxes that you want to have done the same thing when their text is changed and you need their data then you could do this:

$('.target').change(function(event) {
   //do stuff with the "event" object as the object that called the method
)};

that way you can use the same code, for multiple text boxes using the same class without having to rewrite any code.

Everyone points to key_buffer_size first which you have addressed. With 96GB memory I'd be wary of any tiny default value (likely to be only 96M!).

Here's one I made on a 1 Million point set with 3 categories (colored Red, Green, and Blue). Here's a link to the repository if you'd like to try the function. Github Repo

histplot(
    X,
    Y,
    labels,
    bins=2000,
    range=((-3,3),(-3,3)),
    normalize_each_label=True,
    colors = [
        [1,0,0],
        [0,1,0],
        [0,0,1]],
    gain=50)

In case anyone needed the above in swift :

SWIFT 3.0 and above :

this will capitalize your string, make the first letter capital :

viewNoteDateMonth.text  = yourString.capitalized

this will uppercase your string, make all the string upper case :

viewNoteDateMonth.text  = yourString.uppercased()

Well, you can always try WHERE textcolumn LIKE "%SUBSTRING%" - but this is guaranteed to be pretty slow, as your query can't do an index match because you are looking for characters on the left side.

It depends on the field type - a textarea usually won't be saved as VARCHAR, but rather as (a kind of) TEXT field, so you can use the MATCH AGAINST operator.

To get the columns that don't match, simply put a NOT in front of the like: WHERE textcolumn NOT LIKE "%SUBSTRING%".

Whether the search is case-sensitive or not depends on how you stock the data, especially what COLLATION you use. By default, the search will be case-insensitive.

Updated answer to reflect question update:

I say that doing a WHERE field LIKE "%value%" is slower than WHERE field LIKE "value%" if the column field has an index, but this is still considerably faster than getting all values and having your application filter. Both scenario's:

1/ If you do SELECT field FROM table WHERE field LIKE "%value%", MySQL will scan the entire table, and only send the fields containing "value".

2/ If you do SELECT field FROM table and then have your application (in your case PHP) filter only the rows with "value" in it, MySQL will also scan the entire table, but send all the fields to PHP, which then has to do additional work. This is much slower than case #1.

Solution: Please do use the WHERE clause, and use EXPLAIN to see the performance.

Edited Java 8 Solution:

final Drawable drawable = 
    Optional.ofNullable(Common.getDrawableFromUrl(this, product.getMapPath()))
        .orElseGet(() -> getRandomDrawable());

You can declare drawable final in this case.

As Chasmo pointed out, Android doesn't support Java 8 at the moment. So this solution is only possible in other contexts.

Also, this might help finding the actual location the btsnoop_hci.log is being saved:

adb shell "cat /etc/bluetooth/bt_stack.conf | grep FileName"

Here's a quick example:

termList = []
termList.append(('term1', [1,2,3,4]))
termList.append(('term2', [5,6,7,8]))
termList.append(('term3', [9,10,11,12]))

result = [x[1] for x in termList if x[0] == 'term3']

print(result)

Simply:

1. Create UIView as wrapper with auto layout to views around.
2. Put UILabel inside that wrapper. Add constraints that will stick tyour label to edges of wrapper.
3. Put UIButton inside your wrapper, then simple add the same constraints as you did for UILabel.
4. Enjoy your autosized button along with text.

There is also a GUI tool that allows visual JKS creation and certificates importing.

I had to wrap techfoobar's answer in a try..catch block, like so:

try {
  if(typeof arrayName[index] == 'undefined') {
    // does not exist
  }
  else {
  // does exist
  }
} 
catch (error){ /* ignore */ }

...that's how it worked in chrome, anyway (otherwise, the code stopped with an error).

The problem will be that you cannot represent 0.575 exactly as a binary floating point number (eg a double). Though I don't know exactly it seems that the representation closest is probably just a bit lower and so when rounding it uses the true representation and rounds down.

If you want to avoid this problem then use a more appropriate data type. decimal will do what you want:

Math.Round(0.575M, 2, MidpointRounding.AwayFromZero)

Result: 0.58

The reason that 0.75 does the right thing is that it is easy to represent in binary floating point since it is simple 1/2 + 1/4 (ie 2^-1 +2^-2). In general any finite sum of powers of two can be represented in binary floating point. Exceptions are when your powers of 2 span too great a range (eg 2^100+2 is not exactly representable).

Edit to add:

Formatting doubles for output in C# might be of interest in terms of understanding why its so hard to understand that 0.575 is not really 0.575. The DoubleConverter in the accepted answer will show that 0.575 as an Exact String is 0.5749999999999999555910790149937383830547332763671875 You can see from this why rounding give 0.57.

Socket.io uses the EventEmitter pattern to disconnect/connect/check heartbeats so you could do. Client.emit('disconnect');

val means immutable and var means mutable

you can think val as java programming language final key world or c++ language const key world?

CodeIgniter file upload optionally ...works perfectly..... :)

---------- controller ---------

function file()
{
 $this->load->view('includes/template', $data);
}

function valid_file()
{
 $this->form_validation->set_rules('userfile', 'File', 'trim|xss_clean');

 if ($this->form_validation->run()==FALSE) 
 {
    $this->file();
 }
 else
 {
  $config['upload_path']   = './documents/';
  $config['allowed_types'] = 'gif|jpg|png|docx|doc|txt|rtf';
  $config['max_size']      = '1000';
  $config['max_width']     = '1024';
  $config['max_height']    = '768';

  $this->load->library('upload', $config);

  if ( !$this->upload->do_upload('userfile',FALSE))
  {
    $this->form_validation->set_message('checkdoc', $data['error'] = $this->upload->display_errors());

    if($_FILES['userfile']['error'] != 4)
    {
        return false;
    }

  }
  else
  {
    return true;
  }
}

i just use this lines which makes it optionally,

if($_FILES['userfile']['error'] != 4)
{
 return false;
}

$_FILES['userfile']['error'] != 4 is for file required to upload.

you can make it unnecessary by using $_FILES['userfile']['error'] != 4, then it will pass this error for file required and works great with other types of errors if any by using return false , hope it works for u ....

Converting java.util.Data to java.sql.Data will loose hour, minute and second. So if it is possible, I suggest you use java.sql.Timestamp like this:

prepareStatement.setTimestamp(1, new Timestamp(utilDate.getTime()));

There is always sys.exit().

The system library in Python's core library has an exit function which is super handy when prototyping. The code would be along the lines of:

import sys

while True:
    selection = raw_input("U: Create User\nQ: Quit")
    if selection is "Q" or selection is "q":
        print("Quitting")
        sys.exit()
    if selection is "U" or selection is "u":
        print("User")
        #do_something()

     <?php $date= date("Y-m-d");
$time=date("H:m");
$datetime=$date."T".$time;
mysql_query(INSERT INTO table (`dateposted`) VALUES ($datetime));
?>

<form action="form.php" method="get">
<input type="datetime-local" name="date" value="<?php echo $datetime; ?>">
<input type="submit" name="submit" value="submit">

I have stumbled across this question and I will submit my answer that I used and worked pretty well. I had a search box that filtered and array of objects and on my search box I used the (ngModelChange)="onChange($event)"

in my .html

<input type="text" [(ngModel)]="searchText" (ngModelChange)="reSearch(newValue)" placeholder="Search">

then in my component.ts

reSearch(newValue: string) {
    //this.searchText would equal the new value
    //handle my filtering with the new value
}

const x = {obj1: 1, pass: 2, obj2: 3, obj3:26};

const objectWithoutKey = (object, key) => {
  const {[key]: deletedKey, ...otherKeys} = object;
  return otherKeys;
}

console.log(objectWithoutKey(x, 'pass'));

Know that there is an X-XSRF-TOKEN cookie that is set for convenience. Framework like Angular and others set it by default. Check this in the doc https://laravel.com/docs/5.7/csrf#csrf-x-xsrf-token You may like to use it.

The best way is to use the meta, case the cookies are deactivated.

    var xsrfToken = decodeURIComponent(readCookie('XSRF-TOKEN'));
    if (xsrfToken) {
        $.ajaxSetup({
            headers: {
                'X-XSRF-TOKEN': xsrfToken
            }
        });
    } else console.error('....');

Here the recommended meta way (you can put the field any way, but meta is quiet nice):

$.ajaxSetup({
    headers: {
        'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
    }
});   

Note the use of decodeURIComponent(), it's decode from uri format which is used to store the cookie. [otherwise you will get an invalid payload exception in laravel].

Here the section about the csrf cookie in the doc to check : https://laravel.com/docs/5.7/csrf#csrf-x-csrf-token

Also here how laravel (bootstrap.js) is setting it for axios by default:

let token = document.head.querySelector('meta[name="csrf-token"]');

if (token) {
    window.axios.defaults.headers.common['X-CSRF-TOKEN'] = token.content;
} else {
    console.error('CSRF token not found: https://laravel.com/docs/csrf#csrf-x-csrf-token');
} 

you can go check resources/js/bootstrap.js.

And here read cookie function:

   function readCookie(name) {
        var nameEQ = name + "=";
        var ca = document.cookie.split(';');
        for (var i = 0; i < ca.length; i++) {
            var c = ca[i];
            while (c.charAt(0) == ' ') c = c.substring(1, c.length);
            if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length, c.length);
       }
        return null;
    }

Using the @Override annotation on methods that implement those declared by an interface is only valid from Java 6 onward. It's an error in Java 5.

Make sure that your IDE projects are setup to use a Java 6 JRE, and that the "source compatibility" is set to 1.6 or greater:

1. Open the Window > Preferences dialog
2. Browse to Java > Compiler.
3. There, set the "Compiler compliance level" to 1.6.

Remember that Eclipse can override these global settings for a specific project, so check those too.

Update:

The error under Java 5 isn't just with Eclipse; using javac directly from the command line will give you the same error. It is not valid Java 5 source code.

However, you can specify the -target 1.5 option to JDK 6's javac, which will produce a Java 5 version class file from the Java 6 source code.

Try to set a longer max_execution_time:

<IfModule mod_php5.c>
    php_value max_execution_time 300
</IfModule>

<IfModule mod_php7.c>
    php_value max_execution_time 300
</IfModule>

I checked all the answers around the web and the best one seemed to be: (actually it isn't)

<img src="image.png?cache=none">

at first.

However, if you add cache=none parameter (which is static "none" word), it doesn't effect anything, browser still loads from cache.

Solution to this problem was:

<img src="image.png?nocache=<?php echo time(); ?>">

where you basically add unix timestamp to make the parameter dynamic and no cache, it worked.

However, my problem was a little different: I was loading on the fly generated php chart image, and controlling the page with $_GET parameters. I wanted the image to be read from cache when the URL GET parameter stays the same, and do not cache when the GET parameters change.

To solve this problem, I needed to hash $_GET but since it is array here is the solution:

$chart_hash = md5(implode('-', $_GET));
echo "<img src='/images/mychart.png?hash=$chart_hash'>";

Edit:

Although the above solution works just fine, sometimes you want to serve the cached version UNTIL the file is changed. (with the above solution, it disables the cache for that image completely) So, to serve cached image from browser UNTIL there is a change in the image file use:

echo "<img src='/images/mychart.png?hash=" . filemtime('mychart.png') . "'>";

filemtime() gets file modification time.

Both rebase (and cherry-pick) and merge have their advantages and disadvantages. I argue for merge here, but it's worth understanding both. (Look here for an alternate, well-argued answer enumerating cases where rebase is preferred.)

merge is preferred over cherry-pick and rebase for a couple of reasons.

1. Robustness. The SHA1 identifier of a commit identifies it not just in and of itself but also in relation to all other commits that precede it. This offers you a guarantee that the state of the repository at a given SHA1 is identical across all clones. There is (in theory) no chance that someone has done what looks like the same change but is actually corrupting or hijacking your repository. You can cherry-pick in individual changes and they are likely the same, but you have no guarantee. (As a minor secondary issue the new cherry-picked commits will take up extra space if someone else cherry-picks in the same commit again, as they will both be present in the history even if your working copies end up being identical.)
2. Ease of use. People tend to understand the merge workflow fairly easily. rebase tends to be considered more advanced. It's best to understand both, but people who do not want to be experts in version control (which in my experience has included many colleagues who are damn good at what they do, but don't want to spend the extra time) have an easier time just merging.

Even with a merge-heavy workflow rebase and cherry-pick are still useful for particular cases:

1. One downside to merge is cluttered history. rebase prevents a long series of commits from being scattered about in your history, as they would be if you periodically merged in others' changes. That is in fact its main purpose as I use it. What you want to be very careful of, is never to rebase code that you have shared with other repositories. Once a commit is pushed someone else might have committed on top of it, and rebasing will at best cause the kind of duplication discussed above. At worst you can end up with a very confused repository and subtle errors it will take you a long time to ferret out.
2. cherry-pick is useful for sampling out a small subset of changes from a topic branch you've basically decided to discard, but realized there are a couple of useful pieces on.

As for preferring merging many changes over one: it's just a lot simpler. It can get very tedious to do merges of individual changesets once you start having a lot of them. The merge resolution in git (and in Mercurial, and in Bazaar) is very very good. You won't run into major problems merging even long branches most of the time. I generally merge everything all at once and only if I get a large number of conflicts do I back up and re-run the merge piecemeal. Even then I do it in large chunks. As a very real example I had a colleague who had 3 months worth of changes to merge, and got some 9000 conflicts in 250000 line code-base. What we did to fix is do the merge one month's worth at a time: conflicts do not build up linearly, and doing it in pieces results in far fewer than 9000 conflicts. It was still a lot of work, but not as much as trying to do it one commit at a time.

I like and use many of the answers here, so I'd choose whichever works best for you. That said, the method I prefer when I need something like objective-c's @synchronized uses the defer statement introduced in swift 2.

{ 
    objc_sync_enter(lock)
    defer { objc_sync_exit(lock) }

    //
    // code of critical section goes here
    //

} // <-- lock released when this block is exited

The nice thing about this method, is that your critical section can exit the containing block in any fashion desired (e.g., return, break, continue, throw), and "the statements within the defer statement are executed no matter how program control is transferred."1

Node.JS does not fully support ES6 currently, so you can either use asyncawait module or transpile it using Bable.

install

npm install --save asyncawait

helloz.js

var async = require('asyncawait/async');
var await = require('asyncawait/await');

(async (function testingAsyncAwait() {
    await (console.log("Print me!"));
}))();

Assuming your dataframe is mydf:

mydf$task <- factor(mydf$task, levels = c("up", "down", "left", "right", "front", "back"))

In case you need the [] syntax, useful for "edit forms" when you need to pass parameters like id with the route, you would do something like:

[routerLink]="['edit', business._id]"

As for an "about page" with no parameters like yours,

[routerLink]="/about"

or

[routerLink]=['about']

will do the trick.

option-1:

edit \My Documents\IISExpress\config\applicationhost.config file and enable windowsAuthentication, i.e:

<system.webServer>
...
  <security>
...
    <authentication>
      <windowsAuthentication enabled="true" />
    </authentication>
...
  </security>
...
</system.webServer>

option-2:

Unlock windowsAuthentication section in \My Documents\IISExpress\config\applicationhost.config as follows

<add name="WindowsAuthenticationModule" lockItem="false" />

Alter override settings for the required authentication types to 'Allow'

<sectionGroup name="security">
    ...
    <sectionGroup name="system.webServer">
        ...
        <sectionGroup name="authentication">
            <section name="anonymousAuthentication" overrideModeDefault="Allow" />
            ...
            <section name="windowsAuthentication" overrideModeDefault="Allow" />
    </sectionGroup>
</sectionGroup>

Add following in the application's web.config

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
      <security>
        <authentication>
          <windowsAuthentication enabled="true" />
        </authentication>
      </security>
    </system.webServer>
</configuration>

Below link may help: http://learn.iis.net/page.aspx/376/delegating-configuration-to-webconfig-files/

After installing VS 2010 SP1 applying option 1 + 2 may be required to get windows authentication working. In addition, you may need to set anonymous authentication to false in IIS Express applicationhost.config:

<authentication>

            <anonymousAuthentication enabled="false" userName="" />

for VS2015, the IIS Express applicationhost config file may be located here:

$(solutionDir)\.vs\config\applicationhost.config

and the <UseGlobalApplicationHostFile> option in the project file selects the default or solution-specific config file.

This may help you. I may be mistaken but it seems to me that this is related with returning START_STICKY in your onStartCommand() method. You can avoid the service from being called again by returning START_NOT_STICKY instead.

I'd use minlog, personally. It's extremely simple, as the logging class is a few hundred lines of code.

The code below gives the HEX and RGB value of the range whether formatted using conditional formatting or otherwise. If the range is not formatted using Conditional Formatting and you intend to use iColor function in the Excel as UDF. It won't work. Read the below excerpt from MSDN.

Note that the DisplayFormat property does not work in user defined functions. For example, in a worksheet function that returns the interior color of a cell, if you use a line similar to:

Range.DisplayFormat.Interior.ColorIndex

then the worksheet function executes to return a #VALUE! error. If you are not finding color of the conditionally formatted range, then I encourage you to rather use

Range.Interior.ColorIndex

as then the function can also be used as UDF in Excel. Such as iColor(B1,"HEX")

Public Function iColor(rng As Range, Optional formatType As String) As Variant
'formatType: Hex for #RRGGBB, RGB for (R, G, B) and IDX for VBA Color Index
    Dim colorVal As Variant
    colorVal = rng.DisplayFormat.Interior.Color
    Select Case UCase(formatType)
        Case "HEX"
            iColor = "#" & Format(Hex(colorVal Mod 256),"00") & _
                           Format(Hex((colorVal \ 256) Mod 256),"00") & _
                           Format(Hex((colorVal \ 65536)),"00")
        Case "RGB"
            iColor = Format((colorVal Mod 256),"00") & ", " & _
                     Format(((colorVal \ 256) Mod 256),"00") & ", " & _
                     Format((colorVal \ 65536),"00")
        Case "IDX"
            iColor = rng.Interior.ColorIndex
        Case Else
            iColor = colorVal
    End Select
End Function

'Example use of the iColor function
Sub Get_Color_Format()
    Dim rng As Range

    For Each rng In Selection.Cells
        rng.Offset(0, 1).Value = iColor(rng, "HEX")
        rng.Offset(0, 2).Value = iColor(rng, "RGB")
    Next
End Sub

If you want to disable editing the entire grid, you can set IsReadOnly to true on the grid. If you want to disable user to add new rows, you set the property CanUserAddRows="False"

<DataGrid IsReadOnly="True" CanUserAddRows="False" />

Further more you can set IsReadOnly on individual columns to disable editing.

I prefer to avoid using select

     With sheets("sheetname").range("I10") 
          .PasteSpecial Paste:=xlPasteValues, _
                  Operation:=xlNone, _

                  Transpose:=False

You can handle in many ways in Selenium.

You can use direct click operation to Select values

or

you can write general xpath to match all values from calender and click on specific date as per requirement.

I have written detailed post on it.

Hope it will help

Since PyYAML's yaml.load() function parses YAML documents to native Python data structures, you can just access items by key or index. Using the example from the question you linked:

import yaml
with open('tree.yaml', 'r') as f:
    doc = yaml.load(f)

To access branch1 text you would use:

txt = doc["treeroot"]["branch1"]
print txt
"branch1 text"

because, in your YAML document, the value of the branch1 key is under the treeroot key.

Just for the sake of completeness, here is a link to the golang documentation which describes all types. In your case it is numeric types:

uint8       the set of all unsigned  8-bit integers (0 to 255)
uint16      the set of all unsigned 16-bit integers (0 to 65535)
uint32      the set of all unsigned 32-bit integers (0 to 4294967295)
uint64      the set of all unsigned 64-bit integers (0 to 18446744073709551615)

int8        the set of all signed  8-bit integers (-128 to 127)
int16       the set of all signed 16-bit integers (-32768 to 32767)
int32       the set of all signed 32-bit integers (-2147483648 to 2147483647)
int64       the set of all signed 64-bit integers (-9223372036854775808 to 9223372036854775807)

float32     the set of all IEEE-754 32-bit floating-point numbers
float64     the set of all IEEE-754 64-bit floating-point numbers

complex64   the set of all complex numbers with float32 real and imaginary parts
complex128  the set of all complex numbers with float64 real and imaginary parts

byte        alias for uint8
rune        alias for int32

Which means that you need to use float64(integer_value).

I took AhrB's list, while appended three more files. Here is the full list I have used:

sudo rm -rf /usr/local/lib/node /usr/local/lib/node_modules /var/db/receipts/org.nodejs.*
sudo rm -rf /usr/local/include/node /Users/$USER/.npm
sudo rm /usr/local/bin/node
sudo rm /usr/local/share/man/man1/node.1

sudo rm /usr/local/share/systemtap/tapset/node.stp
sudo rm /usr/local/lib/dtrace/node.d
# In case you want to reinstall node with HomeBrew:
# brew install node

First, here's some sample data:

set.seed(1)
dat <- data.frame(one = rnorm(15),
                 two = sample(LETTERS, 15),
                 three = rnorm(15),
                 four = runif(15))
dat <- data.frame(lapply(dat, function(x) { x[sample(15, 5)] <- NA; x }))
head(dat)
#          one  two       three      four
# 1         NA    M  0.80418951 0.8921983
# 2  0.1836433    O -0.05710677        NA
# 3 -0.8356286    L  0.50360797 0.3899895
# 4         NA    E          NA        NA
# 5  0.3295078    S          NA 0.9606180
# 6 -0.8204684 <NA> -1.28459935 0.4346595

Here's our replacement:

dat[["four"]][is.na(dat[["four"]])] <- 0
head(dat)
#          one  two       three      four
# 1         NA    M  0.80418951 0.8921983
# 2  0.1836433    O -0.05710677 0.0000000
# 3 -0.8356286    L  0.50360797 0.3899895
# 4         NA    E          NA 0.0000000
# 5  0.3295078    S          NA 0.9606180
# 6 -0.8204684 <NA> -1.28459935 0.4346595

Alternatively, you can, of course, write dat$four[is.na(dat$four)] <- 0

The related name parameter is actually an option. If we do not set it, Django automatically creates the other side of the relation for us. In the case of the Map model, Django would have created a map_set attribute, allowing access via m.map_set in your example(m being your class instance). The formula Django uses is the name of the model followed by the string _set. The related name parameter thus simply overrides Django’s default rather than providing new behavior.

def eggs(someParameter):
    del spam[3]
    someParameter.insert(3, ' and cats.')


spam = ['apples', 'bananas', 'tofu', 'cats']
eggs(spam)
spam =(','.join(spam))
print(spam)

So the solution depend on whether you adjust the subplot. If you specify plt.subplots_adjust (top, bottom, right, left), you don't want to use the kwargs of bbox_inches='tight' with plt.savefig, as it paradoxically creates whitespace padding. It also allows you to save the image as the same dims as the input image (600x600 input image saves as 600x600 pixel output image).

If you don't care about the output image size consistency, you can omit the plt.subplots_adjust attributes and just use the bbox_inches='tight' and pad_inches=0 kwargs with plt.savefig.

This solution works for matplotlib versions 3.0.1, 3.0.3 and 3.2.1. It also works when you have more than 1 subplot (eg. plt.subplots(2,2,...).

def save_inp_as_output(_img, c_name, dpi=100):
    h, w, _ = _img.shape
    fig, axes = plt.subplots(figsize=(h/dpi, w/dpi))
    fig.subplots_adjust(top=1.0, bottom=0, right=1.0, left=0, hspace=0, wspace=0) 
    axes.imshow(_img)
    axes.axis('off')
    plt.savefig(c_name, dpi=dpi, format='jpeg') 

I had this issue and found that the problem was that I had not registered the JacksonFeature class:

// Create JAX-RS application.
final Application application = new ResourceConfig()
    ...
    .register(JacksonFeature.class);

Without doing this your application does not know how to convert the JSON to a java object.

You can't depend on the file having a BOM. UTF-8 doesn't require it. And non-Unicode encodings don't even have a BOM. There are, however, other ways to detect the encoding.

UTF-32

BOM is 00 00 FE FF (for BE) or FF FE 00 00 (for LE).

But UTF-32 is easy to detect even without a BOM. This is because the Unicode code point range is restricted to U+10FFFF, and thus UTF-32 units always have the pattern 00 {00-10} xx xx (for BE) or xx xx {00-10} 00 (for LE). If the data has a length that's a multiple of 4, and follows one of these patterns, you can safely assume it's UTF-32. False positives are nearly impossible due to the rarity of 00 bytes in byte-oriented encodings.

US-ASCII

No BOM, but you don't need one. ASCII can be easily identified by the lack of bytes in the 80-FF range.

UTF-8

BOM is EF BB BF. But you can't rely on this. Lots of UTF-8 files don't have a BOM, especially if they originated on non-Windows systems.

But you can safely assume that if a file validates as UTF-8, it is UTF-8. False positives are rare.

Specifically, given that the data is not ASCII, the false positive rate for a 2-byte sequence is only 3.9% (1920/49152). For a 7-byte sequence, it's less than 1%. For a 12-byte sequence, it's less than 0.1%. For a 24-byte sequence, it's less than 1 in a million.

UTF-16

BOM is FE FF (for BE) or FF FE (for LE). Note that the UTF-16LE BOM is found at the start of the UTF-32LE BOM, so check UTF-32 first.

If you happen to have a file that consists mainly of ISO-8859-1 characters, having half of the file's bytes be 00 would also be a strong indicator of UTF-16.

Otherwise, the only reliable way to recognize UTF-16 without a BOM is to look for surrogate pairs (D[8-B]xx D[C-F]xx), but non-BMP characters are too rarely-used to make this approach practical.

XML

If your file starts with the bytes 3C 3F 78 6D 6C (i.e., the ASCII characters "<?xml"), then look for an encoding= declaration. If present, then use that encoding. If absent, then assume UTF-8, which is the default XML encoding.

If you need to support EBCDIC, also look for the equivalent sequence 4C 6F A7 94 93.

In general, if you have a file format that contains an encoding declaration, then look for that declaration rather than trying to guess the encoding.

None of the above

There are hundreds of other encodings, which require more effort to detect. I recommend trying Mozilla's charset detector or a .NET port of it.

A reasonable default

If you've ruled out the UTF encodings, and don't have an encoding declaration or statistical detection that points to a different encoding, assume ISO-8859-1 or the closely related Windows-1252. (Note that the latest HTML standard requires a “ISO-8859-1” declaration to be interpreted as Windows-1252.) Being Windows' default code page for English (and other popular languages like Spanish, Portuguese, German, and French), it's the most commonly encountered encoding other than UTF-8.

Just use this:

$(function() {
 $('#watchButton').trigger('click');
});

Give this parent DIV font-size:0. Write like this:

<div style="font-size:0">
  <div style="width:50%; display:inline-table;font-size:15px">A</div>
  <div style="width:50%; display:inline-table;font-size:15px">B</div>
</div>

Your question didnt ask how to use BETWEEN correctly, rather asked for help with the unexpectedly truncated results...

As mentioned/hinting at in the other answers, the problem is that you have time segments in addition to the dates.

In my experience, using date diff is worth the extra wear/tear on the keyboard. It allows you to express exactly what you want, and you are covered.

select * 
from xxx 
where datediff(d, '2012-10-26', dates) >=0
and  datediff(d, dates,'2012-10-27') >=0

using datediff, if the first date is before the second date, you get a positive number. There are several ways to write the above, for instance always having the field first, then the constant. Just flipping the operator. Its a matter of personal preference.

you can be explicit about whether you want to be inclusive or exclusive of the endpoints by dropping one or both equal signs.

BETWEEN will work in your case, because the endpoints are both assumed to be midnight (ie DATEs). If your endpoints were also DATETIME, using BETWEEN may require even more casting. In my mind DATEDIFF was put in our lives to insulate us from those issues.

Go to any page you want to see it in browser right click--> view in browser. this way working with me.

Just for a more animated and cute solution:

$(window).scroll(function(){
  $("#div").stop().animate({"marginTop": ($(window).scrollTop()) + "px", "marginLeft":($(window).scrollLeft()) + "px"}, "slow" );
});

And a pen for those who want to see: http://codepen.io/think123/full/mAxlb, and fork: http://codepen.io/think123/pen/mAxlb

Update: and a non-animated jQuery solution:

$(window).scroll(function(){
  $("#div").css({"margin-top": ($(window).scrollTop()) + "px", "margin-left":($(window).scrollLeft()) + "px"});
});

If you should need to replace the handle with something else entirely, rather than just restyling it:

You can specify custom handle elements by creating and appending the elements and adding the ui-slider-handle class before initialization.

Working Example

$('.slider').append('<div class="my-handle ui-slider-handle"><svg height="18" width="14"><path d="M13,9 5,1 A 10,10 0, 0, 0, 5,17z"/></svg></div>');_x000D_
_x000D_
$('.slider').slider({_x000D_
  range: "min",_x000D_
  value: 10_x000D_
});

.slider .ui-state-default {_x000D_
  background: none;_x000D_
}_x000D_
.slider.ui-slider .ui-slider-handle {_x000D_

Are you looking for "SELECT * FROM temp_tickets GROUP BY ticket_id ORDER BY ticket_id ?

UPDATE

SELECT t.* 
FROM 
(SELECT ticket_id, MAX(id) as id FROM temp_tickets GROUP BY ticket_id) a  
INNER JOIN temp_tickets t ON (t.id = a.id)

More cleaner way using LINQ

var lines = dictionary.Select(kvp => kvp.Key + ": " + kvp.Value.ToString());
textBox3.Text = string.Join(Environment.NewLine, lines);

It doesn't - the C# compiler does :)

So this code:

string x = "hello";
string y = "there";
string z = "chaps";
string all = x + y + z;

actually gets compiled as:

string x = "hello";
string y = "there";
string z = "chaps";
string all = string.Concat(x, y, z);

(Gah - intervening edit removed other bits accidentally.)

The benefit of the C# compiler noticing that there are multiple string concatenations here is that you don't end up creating an intermediate string of x + y which then needs to be copied again as part of the concatenation of (x + y) and z. Instead, we get it all done in one go.

EDIT: Note that the compiler can't do anything if you concatenate in a loop. For example, this code:

string x = "";
foreach (string y in strings)
{
    x += y;
}

just ends up as equivalent to:

string x = "";
foreach (string y in strings)
{
    x = string.Concat(x, y);
}

... so this does generate a lot of garbage, and it's why you should use a StringBuilder for such cases. I have an article going into more details about the two which will hopefully answer further questions.

CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName(1);

See Here for more details.

Or

DateTime dt = DateTime.Now;
Console.WriteLine( dt.ToString( "MMMM" ) );

Or if you want to get the culture-specific abbreviated name.

GetAbbreviatedMonthName(1);

Reference

You can use this (from https://github.com/aspnet/EntityFrameworkCore/issues/1862#issuecomment-451671168 ) :

public static class SqlQueryExtensions
{
    public static IList<T> SqlQuery<T>(this DbContext db, string sql, params object[] parameters) where T : class
    {
        using (var db2 = new ContextForQueryType<T>(db.Database.GetDbConnection()))
        {
            return db2.Query<T>().FromSql(sql, parameters).ToList();
        }
    }

    private class ContextForQueryType<T> : DbContext where T : class
    {
        private readonly DbConnection connection;

        public ContextForQueryType(DbConnection connection)
        {
            this.connection = connection;
        }

        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
        {
            // switch on the connection type name to enable support multiple providers
            // var name = con.GetType().Name;
            optionsBuilder.UseSqlServer(connection, options => options.EnableRetryOnFailure());

            base.OnConfiguring(optionsBuilder);
        }

        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            modelBuilder.Entity<T>().HasNoKey();
            base.OnModelCreating(modelBuilder);
        }
    }
}

And the usage:

    using (var db = new Db())
    {
        var results = db.SqlQuery<ArbitraryType>("select 1 id, 'joe' name");
        //or with an anonymous type like this
        var results2 = db.SqlQuery(() => new { id =1, name=""},"select 1 id, 'joe' name");
    }

Here's another way to do it :) The concept is to create a clip-path polygon with the wave as one side.

This approach is fairly flexible. You can change the position (left, right, top or bottom) in which the wave appears, change the wave function to any function(t) which maps to [0,1]). The polygon can also be used for shape-outside, which lets text flow around the wave when in 'left' or 'right' orientation.

At the end, an example you can uncomment which demonstrates animating the wave.

Here is an alternative method using ls:

(ls x.txt && echo yes) || echo no

If you want to hide any output from ls so you only see yes or no, redirect stdout and stderr to /dev/null:

(ls x.txt >> /dev/null 2>&1 && echo yes) || echo no

I had successfully used the following on Arch Linux (where the -a flag is used for attachments) for several years:

mailx -s "The Subject $( echo -e "\nContent-Type: text/html" [email protected] < email.html

This appended the Content-Type header to the subject header, which worked great until a recent update. Now the new line is filtered out of the -s subject. Presumably, this was done to improve security.

Instead of relying on hacking the subject line, I now use a bash subshell:

(
    echo -e "Content-Type: text/html\n"
    cat mail.html
 ) | mail -s "The Subject" -t [email protected]

And since we are really only using mailx's subject flag, it seems there is no reason not to switch to sendmail as suggested by @dogbane:

(
    echo "To: [email protected]"
    echo "Subject: The Subject"
    echo "Content-Type: text/html"
    echo
    cat mail.html
) | sendmail -t

The use of bash subshells avoids having to create a temporary file.

Why not use a library function to validate the ip address?

>>> ip="241.1.1.112343434" 
>>> socket.inet_aton(ip)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
socket.error: illegal IP address string passed to inet_aton

Important Update : As @equiman points out, there are some USB cables that are for charging only and do not transmit data. Sometimes just swapping cables will help.

Update for some versions of adb, ~/.android/adb_usb.ini has to be removed.

Executive summary: Add the Vendor ID to ~/.android/adb_usb.ini and restart adb

Full Details: Most of the time nothing will need to be done to get the Mac to recognize the phone/device. Seriously, 99% of the time "it just works."

That being said, the quickest way to reset adb is to restart it with the following commands in sequence:

  adb kill-server
  adb devices

But every now and then the adb devices command just fails to find your device. Maybe if you're working with some experimental or prototype or out-of-the-ordinary device, maybe it's just unknown and won't show up.

You can help adb to find your device by telling it about your device's "Vendor ID," essentially providing it with a hint. This can be done by putting the hex Vendor ID in the file ~/.android/adb_usb.ini

But first you have to find the Vendor ID value. Fortunately on Mac this is pretty easy. Launch the System Information application. It is located in the /Applications/Utilities/ folder, or you can get to it via the Apple Menu in the top left corner of the screen, select "About this Mac", then click the "More Info..." button. Screen grab here:

Expand the "Hardware" tree, select "USB", then look for your target device. In the above example, my device is named "SomeDevice" (I did that in photoshop to hide the real device manufacturer). Another example would be a Samsung tablet which shows up as "SAMSUNG_Android" (btw, I didn't have to do anything special to make the Samsung tablet work.) Anyway, click your device and the full details will display in the pane below. This is where it lists the Vendor ID. In my example from the screenshot the value is 0x9d17 -- use this value in the next command

echo 0x9d17 >> ~/.android/adb_usb.ini

It's okay if you didn't already have that adb_usb.ini file before this, most of the time it's just not needed for finding your device so it's not unusual for that file to not be present. The above command will create it or append to the bottom of it if it already exists. Now run the commands listed way above to restart adb and you should be good to go.

adb kill-server ; adb devices

* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached 
123ABC456DEF001 device

The problem is in your playerMovement method. You are creating the string name of your room variables (ID1, ID2, ID3):

letsago = "ID" + str(self.dirDesc.values())

However, what you create is just a str. It is not the variable. Plus, I do not think it is doing what you think its doing:

>>>str({'a':1}.values())
'dict_values([1])'

If you REALLY needed to find the variable this way, you could use the eval function:

>>>foo = 'Hello World!'
>>>eval('foo')
'Hello World!'

or the globals function:

class Foo(object):
    def __init__(self):
        super(Foo, self).__init__()
    def test(self, name):
        print(globals()[name])

foo = Foo()
bar = 'Hello World!'
foo.text('bar')

However, instead I would strongly recommend you rethink you class(es). Your userInterface class is essentially a Room. It shouldn't handle player movement. This should be within another class, maybe GameManager or something like that.

You could try something like this using approach for How to find the last field using 'cut':

Explanation

• rev reverses /home/user/mydir/file_name.c to be c.eman_elif/ridym/resu/emoh/
• cut uses dot (ie /) as the delimiter, and chooses the first field, which is c.eman_elif
• lastly, we reverse it again to get file_name.c

$ VAR="/home/user/mydir/file_name.c"
$ echo $VAR | rev | cut -f1 -d"/" | rev
file_name.c

Below is made by purely MUI Grid system,

With the code below,

// MuiGrid.js

import React from "react";
import { makeStyles } from "@material-ui/core/styles";
import Paper from "@material-ui/core/Paper";
import Grid from "@material-ui/core/Grid";

const useStyles = makeStyles(theme => ({
  root: {
    flexGrow: 1
  },
  paper: {
    padding: theme.spacing(2),
    textAlign: "center",
    color: theme.palette.text.secondary,
    backgroundColor: "#b5b5b5",
    margin: "10px"
  }
}));

export default function FullWidthGrid() {
  const classes = useStyles();

  return (
    <div className={classes.root}>
      <Grid container spacing={0}>
        <Grid item xs={12}>
          <Paper className={classes.paper}>xs=12</Paper>
        </Grid>
        <Grid item xs={12} sm={6}>
          <Paper className={classes.paper}>xs=12 sm=6</Paper>
        </Grid>
        <Grid item xs={12} sm={6}>
          <Paper className={classes.paper}>xs=12 sm=6</Paper>
        </Grid>
        <Grid item xs={6} sm={3}>
          <Paper className={classes.paper}>xs=6 sm=3</Paper>
        </Grid>
        <Grid item xs={6} sm={3}>

        <Grid item xs={6} sm={3}>
          <Paper className={classes.paper}>xs=6 sm=3</Paper>
        </Grid>
      </Grid>
    </div>

Further expanding on Hamid's answer, I wrote a helper class that can be started and stopped repeatedly (for profiling inside a loop).

   class ExecutionTime
   {
      private $startTime;
      private $endTime;
      private $compTime = 0;
      private $sysTime = 0;

      public function Start(){
         $this->startTime = getrusage();
      }

      public function End(){
         $this->endTime = getrusage();
         $this->compTime += $this->runTime($this->endTime, $this->startTime, "utime");
         $this->systemTime += $this->runTime($this->endTime, $this->startTime, "stime");
      }

      private function runTime($ru, $rus, $index) {
         return ($ru["ru_$index.tv_sec"]*1000 + intval($ru["ru_$index.tv_usec"]/1000))
         -  ($rus["ru_$index.tv_sec"]*1000 + intval($rus["ru_$index.tv_usec"]/1000));
      }

      public function __toString(){
         return "This process used " . $this->compTime . " ms for its computations\n" .
                "It spent " . $this->systemTime . " ms in system calls\n";
      }
   }

I know it is an old question. Just want to add my funny obfuscated "Hello world!" in Python 3 and some tips ;)

It is possible to do manually, my tips are:

• use eval and/or exec with encrypted strings

• use [ord(i) for i in s] / ''.join(map(chr, [list of chars goes here])) as simple encryption/decryption

• use obscure variable names

• make it unreadable

• Don't write just 1 or True, write 1&True&0x00000001 ;)

• use different number systems

• add confusing comments like "line 2" on line 10 or "it returns 0" on while loop.

• use __builtins__

• use getattr and setattr

Please try the given code below, hope it will helpful to you,

import java.util.Scanner;

class String55 {
    public static int frequency(String s1,String s2)
    {

        int count=0;
        char ch[]=s1.toCharArray();
        char ch1[]=s2.toCharArray();
        for (int i=0;i<ch.length-1; i++)
        {



                int k=i;

                int j1=i+1;

                    while(k<ch.length && j11<ch1.length && ch[k]==ch1[j11])
                    {

Thank-you.Happy coding.

str1 = "Hello"
str2 = "World"
newstr = " ".join((str1, str2))

That joins str1 and str2 with a space as separators. You can also do "".join(str1, str2, ...). str.join() takes an iterable, so you'd have to put the strings in a list or a tuple.

That's about as efficient as it gets for a builtin method.

if you are outputting the code as html - change /n -->
and do echo $message;

For me the error was misleading. I discovered the true error by testing the errant web service with SoapUI.

var i = "[{a:1,b:2}]",_x000D_
    j = i.replace(/([a-zA-Z0-9]+?):/g, '"$1":').replace(/'/g,'"'),_x000D_
    k = JSON.parse(j);_x000D_
_x000D_
console.log(k)

// => declaring regular expression

[a-zA-Z0-9] => match all a-z, A-Z, 0-9

(): => group all matched elements

$1 => replacement string refers to the first match group in the regex.

g => global flag
