I encountered the same issue in postman, i was selecting Accept in header section and providing the value as "application/json". So i unchecked and selected Content-Type and provided the value as "application/json". That worked!

Specifically to answer "is there a one line way of doing this?"

if 'key' in my_dict: del my_dict['key']

...well, you asked ;-)

You should consider, though, that this way of deleting an object from a dict is not atomic—it is possible that 'key' may be in my_dict during the if statement, but may be deleted before del is executed, in which case del will fail with a KeyError. Given this, it would be safest to either use dict.pop or something along the lines of

try:
    del my_dict['key']
except KeyError:
    pass

which, of course, is definitely not a one-liner.

Leushenko's answer is really cool - solely: the foo example does not compile with GCC, which fails at foo(7), stumbling over the FIRST macro and the actual function call ((_1, __VA_ARGS__), remaining with a surplus comma. Additionally, we are in trouble if we want to provide additional overloads, such as foo(double).

So I decided to elaborate the answer a little further, including to allow a void overload (foo(void) – which caused quite some trouble...).

Idea now is: Define more than one generic in different macros and let select the correct one according to the number of arguments!

Number of arguments is quite easy, based on this answer:

#define foo(...) SELECT(__VA_ARGS__)(__VA_ARGS__)

#define SELECT(...) CONCAT(SELECT_, NARG(__VA_ARGS__))(__VA_ARGS__)
#define CONCAT(X, Y) CONCAT_(X, Y)
#define CONCAT_(X, Y) X ## Y

That's nice, we resolve to either SELECT_1 or SELECT_2 (or more arguments, if you want/need them), so we simply need appropriate defines:

#define SELECT_0() foo_void
#define SELECT_1(_1) _Generic ((_1),    \
        int: foo_int,                   \
        char: foo_char,                 \
        double: foo_double              \
)
#define SELECT_2(_1, _2) _Generic((_1), \
        double: _Generic((_2),          \
                int: foo_double_int     \
        )                               \
)

OK, I added the void overload already – however, this one actually is not covered by the C standard, which does not allow empty variadic arguments, i. e. we then rely on compiler extensions!

At very first, an empty macro call (foo()) still produces a token, but an empty one. So the counting macro actually returns 1 instead of 0 even on empty macro call. We can "easily" eliminate this problem, if we place the comma after __VA_ARGS__ conditionally, depending on the list being empty or not:

#define NARG(...) ARG4_(__VA_ARGS__ COMMA(__VA_ARGS__) 4, 3, 2, 1, 0)

That looked easy, but the COMMA macro is quite a heavy one; fortunately, the topic is already covered in a blog of Jens Gustedt (thanks, Jens). Basic trick is that function macros are not expanded if not followed by parentheses, for further explanations, have a look at Jens' blog... We just have to modify the macros a little to our needs (I'm going to use shorter names and less arguments for brevity).

#define ARGN(...) ARGN_(__VA_ARGS__)

#define HAS_COMMA(...) ARGN(__VA_ARGS__, 1, 1, 1, 0)

        HAS_COMMA(SET_COMMA __VA_ARGS__ ()) \

#define COMMA_0000 ,

// ... (all others with comma)

Good news! At the time of writing, this feature has already been implemented in the 0.10.12-insiders release and carried out through 0.10.14-insiders. Hence we are going to have it in the upcoming version 1.0 Release of VS Code.

For reverse sorting just change the order of x1, x2 for calling the x1.compareTo(x2) method the result will be reverse to one another

Default order

List<String> sortedByName = citiesName.stream().sorted((s1,s2)->s1.compareTo(s2)).collect(Collectors.toList());
System.out.println("Sorted by Name : "+ sortedByName);

Reverse Order

List<String> reverseSortedByName = citiesName.stream().sorted((s1,s2)->s2.compareTo(s1)).collect(Collectors.toList());
System.out.println("Reverse Sorted by Name : "+ reverseSortedByName );

I haven't had any issues using this method:

Use autocomplete="off", add a hidden password field and then another non-hidden one. The browser tries to auto complete the hidden one if it doesn't respect autocomplete="off"

The solution that worked for me was to right click on the project --> Maven --> Update Project then click OK.

You can export collection by clicking on arrow button

and then click on download collection button

Yes, there is a command to find the size of a database in Postgres. It's the following:

SELECT pg_database.datname as "database_name", pg_size_pretty(pg_database_size(pg_database.datname)) AS size_in_mb FROM pg_database ORDER by size_in_mb DESC;

echo $STRING | cut -d " " -f $N

Write to a file with Python's print():

import numpy as np
import sys

stdout_sys = sys.stdout
np.set_printoptions(precision=8) # Sets number of digits of precision.
np.set_printoptions(suppress=True) # Suppress scientific notations.
np.set_printoptions(threshold=sys.maxsize) # Prints the whole arrays.
with open('myfile.txt', 'w') as f:
    sys.stdout = f
    print(nparr)
    sys.stdout = stdout_sys

Use set_printoptions() to customize how the objects are displayed.

In general, that depends on your shell, but if you use bash, zsh, ksh or sh (as provided by dash), the following should work:

if ! type "$foobar_command_name" > /dev/null; then
  # install foobar here
fi

For a real installation script, you'd probably want to be sure that type doesn't return successfully in the case when there is an alias foobar. In bash you could do something like this:

if ! foobar_loc="$(type -p "$foobar_command_name")" || [[ -z $foobar_loc ]]; then
  # install foobar here
fi

It probably aimed to select all the informations in your table. If you use this kind of query (for example in PHP) :

mysql_query("SELECT * FROM newsletter WHERE email = '$email'");

The email ' OR 1=1/* will give this kind of query :

mysql_query("SELECT * FROM newsletter WHERE email = '' OR 1=1/*");

So it selects all the rows (because 1=1 is always true and the rest of the query is 'commented'). But it was not successful

• if strings used in your queries are escaped
• if you don't display all the queries results on a page...

$string = '9,[email protected],8';
$array = explode(',', $string);

For more complicated situations, you may need to use preg_split.

You could do the following:

• Let the shutdown hook set some AtomicBoolean (or volatile boolean) "keepRunning" to false
• (Optionally, .interrupt the working threads if they wait for data in some blocking call)
• Wait for the working threads (executing writeBatch in your case) to finish, by calling the Thread.join() method on the working threads.
• Terminate the program

Some sketchy code:

• Add a static volatile boolean keepRunning = true;

• In run() you change to

  for (int i = 0; i < N && keepRunning; ++i)
      writeBatch(pw, i);
  

• In main() you add:

  final Thread mainThread = Thread.currentThread();
  Runtime.getRuntime().addShutdownHook(new Thread() {
      public void run() {
          keepRunning = false;
          mainThread.join();
      }
  });
  

That's roughly how I do a graceful "reject all clients upon hitting Control-C" in terminal.

From the docs:

When the virtual machine begins its shutdown sequence it will start all registered shutdown hooks in some unspecified order and let them run concurrently. When all the hooks have finished it will then run all uninvoked finalizers if finalization-on-exit has been enabled. Finally, the virtual machine will halt.

That is, a shutdown hook keeps the JVM running until the hook has terminated (returned from the run()-method.

My solution was to create all the launch images.

Then I set the Launch Images Source to the LaunchImage asset, and leave launch screen file blank.

Finally if the project does not have a Launch Screen.xib, then add that file and leave it as is.

You should to use history v4 lib.

Example from there

history.listen((location, action) => {
  console.log(`The current URL is ${location.pathname}${location.search}${location.hash}`)
  console.log(`The last navigation action was ${action}`)
})

I am using Debian 8 live off a USB. I was locked out of the system after 10 min of inactivity. The password that was required to log back in to the system for the user was:

login : Debian Live User
password : live

I hope this helps

To retrieve the entire querystring from the current URL, beginning with the ? character, you can use

location.search

https://developer.mozilla.org/en-US/docs/DOM/window.location

Example:

// URL = https://example.com?a=a%20a&b=b123
console.log(location.search); // Prints "?a=a%20a&b=b123" 

In regards to retrieving specific querystring parameters, while although classes like URLSearchParams and URL exist, they aren't supported by Internet Explorer at this time, and should probably be avoided. Instead, you can try something like this:

/**
 * Accepts either a URL or querystring and returns an object associating 
 * each querystring parameter to its value. 
 *
 * Returns an empty object if no querystring parameters found.
 */
function getUrlParams(urlOrQueryString) {
  if ((i = urlOrQueryString.indexOf('?')) >= 0) {
    const queryString = urlOrQueryString.substring(i+1);
    if (queryString) {
      return _mapUrlParams(queryString);
    } 
  }

  return {};
}

/**
 * Helper function for `getUrlParams()`
 * Builds the querystring parameter to value object map.
 *
 * @param queryString {string} - The full querystring, without the leading '?'.
 */
function _mapUrlParams(queryString) {
  return queryString    
    .split('&') 
    .map(function(keyValueString) { return keyValueString.split('=') })
    .reduce(function(urlParams, [key, value]) {
      if (Number.isInteger(parseInt(value)) && parseInt(value) == value) {
        urlParams[key] = parseInt(value);
      } else {
        urlParams[key] = decodeURI(value);
      }
      return urlParams;
    }, {});
}

You can use the above like so:

// Using location.search
let urlParams = getUrlParams(location.search); // Assume location.search = "?a=1&b=2b2"
console.log(urlParams); // Prints { "a": 1, "b": "2b2" }

// Using a URL string
const url = 'https://example.com?a=A%20A&b=1';
urlParams = getUrlParams(url);
console.log(urlParams); // Prints { "a": "A A", "b": 1 }

// To check if a parameter exists, simply do:
if (urlParams.hasOwnProperty('parameterName') { 
  console.log(urlParams.parameterName);
}

Add a View:

1. Right-Click View Folder
2. Click Add -> View
3. Click Create a strongly-typed view
4. Select your User class
5. Select List as the Scaffold template

Add a controller and action method to call the view:

public ActionResult Index()
{
    var users = DataContext.GetUsers();
    return View(users);
}

Note that using const user = {} as UserType just provides intellisense but at runtime user is empty object {} and has no property inside. that means user.Email will give undefined instead of ""

type UserType = {
    Username: string;
    Email: string;
}

So, use class with constructor for actually creating objects with default properties.

type UserType = {
  Username: string;
  Email: string;
};

class User implements UserType {
  constructor() {
    this.Username = "";
    this.Email = "";
  }

  Username: string;
  Email: string;
}

const myUser = new User();
console.log(myUser); // output: {Username: "", Email: ""}
console.log("val: "+myUser.Email); // output: ""

You can also use interface instead of type

interface UserType {
  Username: string;
  Email: string;
};

...and rest of code remains same.

Actually, you can even skip the constructor part and use it like this:

class User implements UserType {
      Username = ""; // will be added to new obj
      Email: string; // will not be added
}

const myUser = new User();
console.log(myUser); // output: {Username: ""}

It looks like there are many options. The answer depends on your Windows installation. Here is my experience when having the same problem in a Windows 10 fresh install and fix the issue with the following step:

1. Install Visual C++ Redistributable
2. Open XAMPP and select configure in the Apache service
3. Change the port 80 to 9000 or 81 or whatever you want in file httpd.conf on the line Listen 80
4. Change the port on httpd-ssl.conf and change Listen 443 to Listen 441
5. Restart XAMPP and start the Apache service. It works for me.

Note: I'm using XAMPP version 5.6.15 and XAMPP Control Panel version 3.2.2.

You're attempting to free something that isn't a pointer to a "freeable" memory address. Just because something is an address doesn't mean that you need to or should free it.

There are two main types of memory you seem to be confusing - stack memory and heap memory.

• Stack memory lives in the live span of the function. It's temporary space for things that shouldn't grow too big. When you call the function main, it sets aside some memory for your variables you've declared (p,token, and so on).

• Heap memory lives from when you malloc it to when you free it. You can use much more heap memory than you can stack memory. You also need to keep track of it - it's not easy like stack memory!

You have a few errors:

• You're trying to free memory that's not heap memory. Don't do that.

• You're trying to free the inside of a block of memory. When you have in fact allocated a block of memory, you can only free it from the pointer returned by malloc. That is to say, only from the beginning of the block. You can't free a portion of the block from the inside.

For your bit of code here, you probably want to find a way to copy relevant portion of memory to somewhere else...say another block of memory you've set aside. Or you can modify the original string if you want (hint: char value 0 is the null terminator and tells functions like printf to stop reading the string).

EDIT: The malloc function does allocate heap memory*.

"9.9.1 The malloc and free Functions

The C standard library provides an explicit allocator known as the malloc package. Programs allocate blocks from the heap by calling the malloc function."

~Computer Systems : A Programmer's Perspective, 2nd Edition, Bryant & O'Hallaron, 2011

EDIT 2: * The C standard does not, in fact, specify anything about the heap or the stack. However, for anyone learning on a relevant desktop/laptop machine, the distinction is probably unnecessary and confusing if anything, especially if you're learning about how your program is stored and executed. When you find yourself working on something like an AVR microcontroller as H2CO3 has, it is definitely worthwhile to note all the differences, which from my own experience with embedded systems, extend well past memory allocation.

You can push multiple elements into an array in the following way

var a = [];_x000D_
    _x000D_
a.push(1, 2, 3);_x000D_
_x000D_
console.log(a);

One thing __init__.py allows is converting a module to a package without breaking the API or creating extraneous nested namespaces or private modules*. This helps when I want to extend a namespace.

If I have a file util.py containing

def foo():
    ...

then users will access foo with

from util import foo

If I then want to add utility functions for database interaction, and I want them to have their own namespace under util, I'll need a new directory**, and to keep API compatibility (so that from util import foo still works), I'll call it util/. I could move util.py into util/ like so,

util/
  __init__.py
  util.py
  db.py

and in util/__init__.py do

from util import *

but this is redundant. Instead of having a util/util.py file, we can just put the util.py contents in __init__.py and the user can now

from util import foo
from util.db import check_schema

I think this nicely highlights how a util package's __init__.py acts in a similar way to a util module

* this is hinted at in the other answers, but I want to highlight it here
** short of employing import gymnastics. Note it won't work to create a new package with the same name as the file, see this

For Python 3 users:

changing the encoding from 'ascii' to 'latin1' works.

Also, you can try finding the encoding automatically by reading the top 10000 bytes using the below snippet:

import chardet  
with open("dataset_path", 'rb') as rawdata:  
            result = chardet.detect(rawdata.read(10000))  
print(result)

I just did it very simply using onpause and onplay properties of the html video tag. Create some javascript function to toggle a global variable so that the page knows the status of the video for other functions.

Javascript below:

   // onPause function
   function videoPause() {
      videoPlaying = 0;
   }

   // onPause function
   function videoPlay() {
      videoPlaying = 1;
   }

Html video tag:

<video id="mainVideo" width="660" controls onplay="videoPlay();" onpause="videoPause();" >
                             <source src="video/myvideo.mp4" type="video/mp4">

                            </video>

than you can use onclick javascript to do something depending on the status variable in this case videoPlaying.

hope this helps...

For jQuery 1.6+:

For jQuery < 1.6:

$(':input','#myform')
  .not(':button, :submit, :reset, :hidden')
  .val('')
  .removeAttr('checked')
  .removeAttr('selected');

Please see this post: Resetting a multi-stage form with jQuery

Or

$('#myform')[0].reset();

As jQuery suggests:

To retrieve and change DOM properties such as the checked, selected, or disabled state of form elements, use the .prop() method.

also had same problem once,

if you are unable to solve the problem you can run the following command on command line
chrome.exe --user-data-dir="C://Chrome dev session" --disable-web-security

Note: you have to navigate to the installation path of your chrome.
For example:cd C:\Program Files\Google\Chrome\Application

A developer session chrome browser will be opened, you can now launch your app on the new chrome browse.
I hope this should be helpful

I believe it's safer to remove the tail slash('/') before doing substring. Because I got an empty string in my scenario.

window.alert((window.location.pathname).replace(/\/$/, "").substr((window.location.pathname.replace(/\/$/, "")).lastIndexOf('/') + 1));

Only using Session.Clear() when a user logs out can pose a security hole. As the session is still valid as far as the Web Server is concerned. It is then a reasonably trivial matter to sniff, and grab the session Id, and hijack that session.

For this reason, when logging a user out it would be safer and more sensible to use Session.Abandon() so that the session is destroyed, and a new session created (even though the logout UI page would be part of the new session, the new session would not have any of the users details in it and hijacking the new session would be equivalent to having a fresh session, hence it would be mute).

just parse as an array:

Review[] reviews = new Gson().fromJson(jsonString, Review[].class);

then if you need you can also create a list in this way:

List<Review> asList = Arrays.asList(reviews);

Sounds like you're calling sp_executesql with a VARCHAR statement, when it needs to be NVARCHAR.

e.g. This will give the error because @SQL needs to be NVARCHAR

DECLARE @SQL VARCHAR(100)
SET @SQL = 'SELECT TOP 1 * FROM sys.tables'
EXECUTE sp_executesql @SQL

So:

DECLARE @SQL NVARCHAR(100)
SET @SQL = 'SELECT TOP 1 * FROM sys.tables'
EXECUTE sp_executesql @SQL

In simple terms:

var = variable

val = variable + final

You can use "wildcards" with MATCH so assuming "ASDFGHJK" in H1 as per Peter's reply you can use this regular formula

=INDEX(G:G,MATCH("*"&H1&"*",G:G,0)+3)

MATCH can only reference a single column or row so if you want to search 6 columns you either have to set up a formula with 6 MATCH functions or change to another approach - try this "array formula", assuming search data in A2:G100

=INDIRECT("R"&REPLACE(TEXT(MIN(IF(ISNUMBER(SEARCH(H1,A2:G100)),(ROW(A2:G100)+3)*1000+COLUMN(A2:G100))),"000000"),4,0,"C"),FALSE)

I got this problem after moving a project and deleting it's packages folder. Nuget was showning that MSTest.TestAdapter and MSTest.TestFramework v 1.3.2 was installed. The fix seemed to be to open VS as administrator and build After that I was able to re-open and build without having admin priviledge.

It's generally not a real good idea to import the VisualBasic libraries into C# programs (not because they won't work, but just for compatibility, style, and ability to upgrade), but you can call Microsoft.VisualBasic.Interaction.InputBox() to display the kind of box you're looking for.

If you can create a Windows.Forms object, that would be best, but you say you cannot do that.

The modulus is a mathematical operation, sometimes described as "clock arithmetic." I find that describing it as simply a remainder is misleading and confusing because it masks the real reason it is used so much in computer science. It really is used to wrap around cycles.

Think of a clock: Suppose you look at a clock in "military" time, where the range of times goes from 0:00 - 23.59. Now if you wanted something to happen every day at midnight, you would want the current time mod 24 to be zero:

if (hour % 24 == 0):

You can think of all hours in history wrapping around a circle of 24 hours over and over and the current hour of the day is that infinitely long number mod 24. It is a much more profound concept than just a remainder, it is a mathematical way to deal with cycles and it is very important in computer science. It is also used to wrap around arrays, allowing you to increase the index and use the modulus to wrap back to the beginning after you reach the end of the array.

You can use @@ROWCOUNT to check whether row should be inserted or updated:

update table1 
set name = 'val2', itemname = 'val3', itemcatName = 'val4', itemQty = 'val5'
where id = 'val1'
if @@ROWCOUNT = 0
insert into table1(id, name, itemname, itemcatName, itemQty)
values('val1', 'val2', 'val3', 'val4', 'val5')

in this case if update fails, the new row will be inserted

Unpopular opinion from 2020:

When it comes to ASP.NET apps I still prefer WebClient over HttpClient because:

1. The modern implementation comes with async/awaitable task-based methods
2. Has smaller memory footprint and 2x-5x faster (other answers already mention that)
3. It's suggested to "reuse a single instance of HttpClient for the lifetime of your application". But ASP.NET has no "lifetime of application", only lifetime of a request.

I can't see a new-line after that last brace.

As you know: "If a source file that is not empty does not end in a new-line character, ... the behavior is undefined".

In short, they are equivalent. Let's have a history view:

(1) at first, the function looks like this.

    class MySubClass(MySuperClass):
        def __init__(self):
            MySuperClass.__init__(self)

(2) to make code more abstract (and more portable). A common method to get Super-Class is invented like:

    super(<class>, <instance>)

And init function can be:

    class MySubClassBetter(MySuperClass):
        def __init__(self):
            super(MySubClassBetter, self).__init__()

However requiring an explicit passing of both the class and instance break the DRY (Don't Repeat Yourself) rule a bit.

(3) in V3. It is more smart,

    super()

is enough in most case. You can refer to http://www.python.org/dev/peps/pep-3135/

A callable piece of code (routine) can be a Sub (called for a side effect/what it does) or a Function (called for its return value) or a mixture of both. As the docs for MsgBox

Displays a message in a dialog box, waits for the user to click a button, and returns a value indicating which button the user clicked.

MsgBox(prompt[, buttons][, title][, helpfile, context])

indicate, this routine is of the third kind.

The syntactical rules of VBScript are simple:

Use parameter list () when calling a (routine as a) Function

If you want to display a message to the user and need to know the user's reponse:

Dim MyVar
MyVar = MsgBox ("Hello World!", 65, "MsgBox Example")
   ' MyVar contains either 1 or 2, depending on which button is clicked.

Don't use parameter list () when calling a (routine as a) Sub

If you want to display a message to the user and are not interested in the response:

MsgBox "Hello World!", 65, "MsgBox Example"

This beautiful simplicity is messed up by:

The design flaw of using () for parameter lists and to force call-by-value semantics

>> Sub S(n) : n = n + 1 : End Sub
>> n = 1
>> S n
>> WScript.Echo n
>> S (n)
>> WScript.Echo n
>>
2
2

S (n) does not mean "call S with n", but "call S with a copy of n's value". Programmers seeing that

>> s = "value"
>> MsgBox(s)

'works' are in for a suprise when they try:

>> MsgBox(s, 65, "MsgBox Example")
>>
Error Number:       1044
Error Description:  Cannot use parentheses when calling a Sub

The compiler's leniency with regard to empty () in a Sub call. The 'pure' Sub Randomize (called for the side effect of setting the random seed) can be called by

Randomize()

although the () can neither mean "give me your return value) nor "pass something by value". A bit more strictness here would force prgrammers to be aware of the difference in

Randomize n

and

Randomize (n)

The Call statement that allows parameter list () in Sub calls:

s = "value" Call MsgBox(s, 65, "MsgBox Example")

which further encourage programmers to use () without thinking.

(Based on What do you mean "cannot use parentheses?")

Go to Settings->Basic, on top you will find a Switch button which will say App is in development mode.

Click on in development switch button, it will ask you to make app live, and after providing all necessary things, it will become live.

In my humble opinion the best way is to just add a full day in milliseconds, depending on how you factor your code it can mess up if your on the last day of the month.

for example Feb 28 or march 31.

Here is an example of how i would do it:

var current = new Date(); //'Mar 11 2015' current.getTime() = 1426060964567
var followingDay = new Date(current.getTime() + 86400000); // + 1 day in ms
followingDay.toLocaleDateString();

imo this insures accuracy

here is another example i Do not like that can work for you but not as clean that dose the above

var today = new Date('12/31/2015');
var tomorrow = new Date(today);
tomorrow.setDate(today.getDate()+1);
tomorrow.toLocaleDateString();

imho this === 'POOP'

So some of you have had gripes about my millisecond approach because of day light savings time. So Im going to bash this out. First, Some countries and states do not have Day light savings time. Second Adding exactly 24 hours is a full day. If the date number dose not change once a year but then gets fixed 6 months later i don't see a problem there. But for the purpose of being definite and having to deal with allot the evil Date() i have thought this through and now thoroughly hate Date. So this is my new Approach

var dd = new Date(); // or any date and time you care about 
var dateArray =  dd.toISOString().split('T')[0].split('-').concat( dd.toISOString().split('T')[1].split(':') );
// ["2016", "07", "04", "00", "17", "58.849Z"] at Z 

Now for the fun part!

var date = { 
    day: dateArray[2],
    month: dateArray[1],
    year: dateArray[0],
    hour: dateArray[3],
    minutes: dateArray[4],
    seconds:dateArray[5].split('.')[0],
    milliseconds: dateArray[5].split('.')[1].replace('Z','')
}

now we have our Official Valid international Date Object clearly written out at Zulu meridian. Now to change the date

  dd.setDate(dd.getDate()+1); // this gives you one full calendar date forward
  tomorrow.setDate(dd.getTime() + 86400000);// this gives your 24 hours into the future. do what you want with it.

Tabview is really good. Worked with 200+MB files that displayed nicely which were buggy with LibreOffice as well as csv plugin in gvim.

The Anaconda version is available here: https://anaconda.org/bioconda/tabview

This error means that for whatever reason the client cannot connect to the port on the computer running server script. This can be caused by few things, like lack of routing to the destination, but since you can ping the server, it should not be the case. The other reason might be that you have a firewall somewhere between your client and the server - it could be on server itself or on the client. Given your network addressing, I assume both server and client are on the same LAN, so there shouldn't be any router/firewall involved that could block the traffic. In this case, I'd try the following:

• check if you really have that port listening on the server (this should tell you if your code does what you think it should): based on your OS, but on linux you could do something like netstat -ntulp
• check from the server, if you're accepting the connections to the server: again based on your OS, but telnet LISTENING_IP LISTENING_PORT should do the job
• check if you can access the port of the server from the client, but not using the code: just us the telnet (or appropriate command for your OS) from the client

and then let us know the findings.

Yes, you can do that, but only if #b is after #a in the HTML.

If #b comes immediately after #a: http://jsfiddle.net/u7tYE/

#a:hover + #b {
    background: #ccc
}

<div id="a">Div A</div>
<div id="b">Div B</div>

That's using the adjacent sibling combinator (+).

If there are other elements between #a and #b, you can use this: http://jsfiddle.net/u7tYE/1/

#a:hover ~ #b {
    background: #ccc
}

<div id="a">Div A</div>
<div>random other elements</div>
<div>random other elements</div>
<div>random other elements</div>
<div id="b">Div B</div>

That's using the general sibling combinator (~).

Both + and ~ work in all modern browsers and IE7+

If #b is a descendant of #a, you can simply use #a:hover #b.

ALTERNATIVE: You can use pure CSS to do this by positioning the second element before the first. The first div is first in markup, but positioned to the right or below the second. It will work as if it were a previous sibling.

Like other said you can't use the "-" in python naming, there are many workarounds, one such workaround which would be useful if you had to add multiple modules from a path is using sys.path

For example if your structure is like this:

foo-bar
+-- barfoo.py
+-- __init__.py

import sys
sys.path.append('foo-bar')

import barfoo

Just access the Priority property of the object returned from the pipeline:

$var = (Get-WSManInstance -enumerate wmicimv2/win32_process).Priority

(This won't work if Get-WSManInstance returns multiple objects.²)

For the second question: to get two properties there are several options, problably the simplest is to have have one variable* containing an object with two separate properties:

$var = (Get-WSManInstance -enumerate wmicimv2/win32_process | select -first 1 Priority, ProcessID)

and then use, assuming only one process:

$var.Priority

and

$var.ProcessID

If there are multiple processes $var will be an array which you can index, so to get the properties of the first process (using the array literal syntax @(...) so it is always a collection¹):

$var = @(Get-WSManInstance -enumerate wmicimv2/win32_process | select -first 1 Priority, ProcessID)

and then use:

$var[0].Priority
$var[0].ProcessID

¹ PowerShell helpfully for the command line, but not so helpfully in scripts has some extra logic when assigning the result of a pipeline to a variable: if no objects are returned then set $null, if one is returned then that object is assigned, otherwise an array is assigned. Forcing an array returns an array with zero, one or more (respectively) elements.

² This changes in PowerShell V3 (at the time of writing in Release Candidate), using a member property on an array of objects will return an array of the value of those properties.

Before stumbling onto this post, I came up with this solution - to toggle the TopMost property:

this.TopMost = true;
this.TopMost = false;

I have this code in my form's constructor, eg:

public MyForm()
{
    //...

    // Brint-to-front hack
    this.TopMost = true;
    this.TopMost = false;

    //...
}

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.

try to use this one on your view it worked for me:

<View
    android:id="@+id/fucused"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:focusable="true"
    android:focusableInTouchMode="true"/>

Using class members to give default values works very well just so long as you are careful only to do it with immutable values. If you try to do it with a list or a dict that would be pretty deadly. It also works where the instance attribute is a reference to a class just so long as the default value is None.

I've seen this technique used very successfully in repoze which is a framework that runs on top of Zope. The advantage here is not just that when your class is persisted to the database only the non-default attributes need to be saved, but also when you need to add a new field into the schema all the existing objects see the new field with its default value without any need to actually change the stored data.

I find it also works well in more general coding, but it's a style thing. Use whatever you are happiest with.

128M == 134217728, the number you are seeing.

The memory limit is working fine. When it says it tried to allocate 32 bytes, that the amount requested by the last operation before failing.

Are you building any huge arrays or reading large text files? If so, remember to free any memory you don't need anymore, or break the task down into smaller steps.

@Abdel Olakara answer donese not work in .net 3.5, should be modified as below:

    public static void ByteArrayToStructure<T>(byte[] bytearray, ref T obj)
    {
        int len = Marshal.SizeOf(obj);
        IntPtr i = Marshal.AllocHGlobal(len);
        Marshal.Copy(bytearray, 0, i, len);
        obj = (T)Marshal.PtrToStructure(i, typeof(T));
        Marshal.FreeHGlobal(i);
    }

You have the right idea, as documentation shows:

http://docs.jquery.com/CSS/css#namevalue

Are you sure you're correctly identify this with class or id?

For example, if your class is myElementClass

$('.myElementClass').css('text-align','center');

Also, I haven't worked with Firebug in a while, but are you looking at the dom and not the html? Your source isn't changed by javascript, but the dom is. Look in the dom tab and see if the change was applied.

You should not. If your private methods have enough complexity that must be tested, you should put them on another class. Keep high cohesion, a class should have only one purpose. The class public interface should be enough.

This didn't work,

android:background="@android:color/transparent"

Setting the webview background color as worked

webView.setBackgroundColor(0)

Additionally, I set window background drawable as transparent

In almost every language with arrays you can't really go wrong with A[A.size-1]. I can't think of an example of a language with 1 based arrays (as opposed to zero based).

inside your onClickListener.onClick, put

getFragmentManager().beginTransaction().replace(R.id.container, new tasks()).commit();

In another word, in your mycontacts.class

public class mycontacts extends Fragment {

    public mycontacts() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        final View v = super.getView(position, convertView, parent);
        ImageView purple = (ImageView) v.findViewById(R.id.imageView1);
        purple.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                getFragmentManager()
                        .beginTransaction()
                        .replace(R.id.container, new tasks())
                        .commit();
            }
        });
        return view;

    }
}

now, remember R.id.container is the container (FrameLayout or other layouts) for the activity that calls the fragment

The easiest way to do this is to click on the Terminate button(red square) in the console:

If you aren't using jQuery, it gets ugly. Here's a snippet that should work on all new browsers. The behavior is different in Quirks mode and standards mode in IE. This takes care of it.

var elem = (document.compatMode === "CSS1Compat") ? 
    document.documentElement :
    document.body;

var height = elem.clientHeight;
var width = elem.clientWidth;

Is the maximum recommended title length really 50?

I have believed this for years, but as I just noticed the documentation of "git commit" actually states

$ git help commit | grep -C 1 50
      Though not required, it’s a good idea to begin the commit message with
      a single short (less than 50 character) line summarizing the change,
      followed by a blank line and then a more thorough description. The text

$  git version
git version 2.11.0

One could argue that "less then 50" can only mean "no longer than 49".

I think this is what your looking for:

    var objs= (from c in List_Objects 
orderby c.TypeID  select c).GroupBy(g=>g.TypeID).Select(x=>x.FirstOrDefault());      

Similar to this Returning a Distinct IQueryable with LINQ?

Creating a 350 characters GUID:

dbms_random.STRING ('a', 350) - returning string in mixed case alpha characters

dbms_random.STRING ('x', 350) - returning string in uppercase alpha-numeric characters

The problem is that you can't use a list as the key in a dict, since dict keys need to be immutable. Use a tuple instead.

This is a list:

[x, y]

This is a tuple:

(x, y)

Note that in most cases, the ( and ) are optional, since , is what actually defines a tuple (as long as it's not surrounded by [] or {}, or used as a function argument).

You might find the section on tuples in the Python tutorial useful:

Though tuples may seem similar to lists, they are often used in different situations and for different purposes. Tuples are immutable, and usually contain an heterogeneous sequence of elements that are accessed via unpacking (see later in this section) or indexing (or even by attribute in the case of namedtuples). Lists are mutable, and their elements are usually homogeneous and are accessed by iterating over the list.

And in the section on dictionaries:

Unlike sequences, which are indexed by a range of numbers, dictionaries are indexed by keys, which can be any immutable type; strings and numbers can always be keys. Tuples can be used as keys if they contain only strings, numbers, or tuples; if a tuple contains any mutable object either directly or indirectly, it cannot be used as a key. You can’t use lists as keys, since lists can be modified in place using index assignments, slice assignments, or methods like append() and extend().

In case you're wondering what the error message means, it's complaining because there's no built-in hash function for lists (by design), and dictionaries are implemented as hash tables.

You should configure the sonar-runner to use your existing SonarQube server. To do so, you need to update its conf/sonar-runner.properties file and specify the SonarQube server URL, username, password, and JDBC URL as well. See https://docs.sonarqube.org/display/SCAN/Analyzing+with+SonarQube+Scanner for details.

If you don't yet have an up and running SonarQube server, then you can launch one locally (with the default configuration) - it will bind to http://localhost:9000 and work with the default sonar-runner configuration. See https://docs.sonarqube.org/latest/setup/get-started-2-minutes/ for details on how to get started with the SonarQube server.

For me, it works,

git push -f heroku otherBranch:master

The -f (force flag) is recommended in order to avoid conflicts with other developers’ pushes. Since you are not using Git for your revision control, but as a transport only, using the force flag is a reasonable practice.

In Windows 10 you might also want to delete Windows Explorer's override for file extension association:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.ps1\UserChoice

in addition to the HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\Shell\open\command change mentioned in other answers.

See https://stackoverflow.com/a/2697804/1360907

CSS3 can solve this problem. Unfortunately it's only supported on 60% of used browsers nowadays.

For IE and iOS you can't turn off resizing but you can limit the textarea dimension by setting its width and height.

/* One can also turn on/off specific axis. Defaults to both on. */
textarea { resize:vertical; } /* none|horizontal|vertical|both */

I've found a better way how to manage JS packages in my project with NPM Gulp/Grunt task runners. I don't like the idea to have a NPM with another layer of javascript library to handle the "automation", and my number one requirement is to simple run the npm update without any other worries about to if I need to run gulp stuff, if it successfully copied everything and vice versa.

The NPM way:

• The JS minifier is already bundled in the ASP.net core, look for bundleconfig.json so this is not an issue for me (not compiling something custom)
• The good thing about NPM is that is have a good file structure so I can always find the pre-compiled/minified versions of the dependencies under the node_modules/module/dist
• I'm using an NPM node_modules/.hooks/{eventname} script which is handling the copy/update/delete of the Project/wwwroot/lib/module/dist/.js files, you can find the documentation here https://docs.npmjs.com/misc/scripts (I'll update the script that I'm using to git once it'll be more polished) I don't need additional task runners (.js tools which I don't like) what keeps my project clean and simple.

The python way:

https://pypi.python.org/pyp... but in this case you need to maintain the sources manually

@tvanfosson rocks with his answer.

However, I would suggest an improvement within js and a small controller check.

When we use @Url helper to call an action, we are going to receive a formatted html. It would be better to update the content (.html) not the actual element (.replaceWith).

More about at: What's the difference between jQuery's replaceWith() and html()?

$.get( '@Url.Action("details","user", new { id = Model.ID } )', function(data) {
    $('#detailsDiv').html(data);
}); 

This is specially useful in trees, where the content can be changed several times.

At the controller we can reuse the action depending on requester:

public ActionResult Details( int id )
{
    var model = GetFooModel();
    if (Request.IsAjaxRequest())
    {
        return PartialView( "UserDetails", model );
    }
    return View(model);
}

A C++14 version of the answer provided by R. Martinho Fernandes would be:

#include <type_traits>

template <typename E>
constexpr auto to_underlying(E e) noexcept
{
    return static_cast<std::underlying_type_t<E>>(e);
}

As with the previous answer, this will work with any kind of enum and underlying type. I have added the noexcept keyword as it will never throw an exception.

Everything in the java.lang package is implicitly imported (including String) and you do not need to do so yourself. This is simply a feature of the Java language. ArrayList and HashMap are however in the java.util package, which is not implicitly imported.

The package java.lang mostly includes essential features, such a class version of primitives, basic exceptions and the Object class. This being integral to most programs, forcing people to import them is redundant and thus the contents of this package are implicitly imported.

I understand that the answer was useful however for some reason it does not work for me however I have moved the situation with the following code and it is perfect

    <?php

$codigoarticulo = $_POST['codigoarticulo'];
$nombrearticulo = $_POST['nombrearticulo'];
$seccion        = $_POST['seccion'];
$precio         = $_POST['precio'];
$fecha          = $_POST['fecha'];
$importado      = $_POST['importado'];
$paisdeorigen   = $_POST['paisdeorigen'];
try {

  $server = 'mysql: host=localhost; dbname=usuarios';
  $user   = 'root';
  $pass   = '';
  $base   = new PDO($server, $user, $pass);

  $base->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

  $base->query("SET character_set_results = 'utf8',
                     character_set_client = 'utf8',
                     character_set_connection = 'utf8',
                     character_set_database = 'utf8',
                     character_set_server = 'utf8'");

  $base->exec("SET character_set_results = 'utf8',

An XSD is included with EntLib 5, and is installed in the Visual Studio schema directory. In my case, it could be found at:

C:\Program Files (x86)\Microsoft Visual Studio 10.0\Xml\Schemas\EnterpriseLibrary.Configuration.xsd

CONTEXT

• Visual Studio 2010
• Enterprise Library 5

STEPS TO REMOVE THE WARNINGS

1. open app.config in your Visual Studio project
2. right click in the XML Document editor, select "Properties"
3. add the fully qualified path to the "EnterpriseLibrary.Configuration.xsd"

ASIDE

It is worth repeating that these "Error List" "Messages" ("Could not find schema information for the element") are only visible when you open the app.config file. If you "Close All Documents" and compile... no messages will be reported.

I solved the problem with the following steps:

1. Open "services.msc" from command / Windows RUN.

2. Find the service (which is greyed out).

3. Double click on that service and go to the "Recovery" tab.

4. Ensure that

   • First Failure action is selected as "Take No action".
   • Second Failure action is selected as "Take No action".
   • Subsequent Failures action is selected as "Take No action".

   and Press OK.

Now, the service will not try to restart and you can able to delete the greyed out service from services list (i.e. greyed out will be gone).

Check out the device model / machine name, DO NOT use the point/pixel count in your code directly, it's hard code and meaningless for the device hardware, the device model is the only unique identifier for a type of device to match.

#import <sys/utsname.h>

NSString* deviceName()
{
    struct utsname systemInfo;
    uname(&systemInfo);

    return [NSString stringWithCString:systemInfo.machine
                          encoding:NSUTF8StringEncoding];
}

Result:

@"iPhone10,3" on iPhone X (CDMA)
@"iPhone10,6" on iPhone X (GSM)

Refer to this answer.

Full code implementation:

#import <sys/utsname.h>

NSString * GetDeviceModel(void)
{
    static dispatch_once_t onceToken;
    static NSString *strModelID = nil;

    dispatch_once(&onceToken, ^{
#if TARGET_IPHONE_SIMULATOR
        strModelID = NSProcessInfo.processInfo.environment[@"SIMULATOR_MODEL_IDENTIFIER"];
#else
        struct utsname systemInfo;

        uname(&systemInfo);
        strModelID = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding];
#endif
    });

    return strModelID;
}

// See the `Hardware strings` in https://en.wikipedia.org/wiki/List_of_iOS_devices
BOOL IsiPhoneX(void)
{
    NSString *strModelID = GetDeviceModel();

    return [strModelID isEqualToString:@"iPhone10,3"] || [strModelID isEqualToString:@"iPhone10,6"];
}

BOOL IsNotchiPhone(void)
{
    NSArray<NSString *> *notchiModels = @[
        @"iPhone10,3", @"iPhone10,6", // iPhone X
        @"iPhone11,2", @"iPhone11,4", @"iPhone11,6", // iPhone XS (Max)
        @"iPhone11,8", // iPhone XR
        @"iPhone12,1", @"iPhone12,3", @"iPhone12,5", // iPhone 11 (Pro (Max))
        @"iPhone13,1", @"iPhone13,2", @"iPhone13,3", @"iPhone13,4", // iPhone 12 ([mini]|[Pro (Max)])
    ];

    return [notchiModels containsObject:GetDeviceModel()];
}

Swift 2.0:

1. Replace default section header with fully customisable UILabel.

Implement viewForHeaderInSection, like so:

  override func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {

    let sectionTitle: String = self.tableView(tableView, titleForHeaderInSection: section)!
    if sectionTitle == "" {
      return nil
    }

    let title: UILabel = UILabel()

    title.text = sectionTitle
    title.textColor = UIColor(red: 0.0, green: 0.54, blue: 0.0, alpha: 0.8)
    title.backgroundColor = UIColor.clearColor()
    title.font = UIFont.boldSystemFontOfSize(15)

    return title
  }

2. Alter the default header (retains default).

Implement willDisplayHeaderView, like so:

  override func tableView(tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {

    if let view = view as? UITableViewHeaderFooterView {
      view.backgroundView?.backgroundColor = UIColor.blueColor()
      view.textLabel!.backgroundColor = UIColor.clearColor()
      view.textLabel!.textColor = UIColor.whiteColor()
      view.textLabel!.font = UIFont.boldSystemFontOfSize(15)
    }
  }

Remember: If you're using static cells, the first section header is padded higher than other section headers due to the top of the UITableView; to fix this:

Implement heightForHeaderInSection, like so:

  override func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {

    return 30.0 // Or whatever height you want!
  }

Use:

document.location.href = "http://yoursite.com" + document.getElementById('somefield');

That would get the value of some text field or hidden field, and add it to your site URL to get a new URL (href). You can modify this to suit your needs.

An answer that helps those who desperately want to get rid of the redirect cache:

Chrome caches the 301 redirect infinitely (in the local disk cache). To clear this cache:

• open your DevTools (press F12)
• on the Network tab check the "Disable cache" checkbox
• keep DevTools open and reload the page (press F5)

When everything is okay, you can uncheck "Disable cache" and everything will continue to work as expected.

Though the carret will be preferable way to do this here's one more approach using macro that constructs a command by the passed arguments:

@echo off
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
set "{{=setlocal enableDelayedExpansion&for %%a in (" & set "}}="::end::" ) do if "%%~a" neq "::end::" (set command=!command! %%a) else (call !command! & endlocal)"
:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

%{{%
    echo
    "command"
    written
    on a
    few lines
%}}%

command is easier to read without the carets but using special symbols e.g. brackets,redirection and so on will break it. So you can this for more simpler cases. Though you can still enclose parameters in double quotes

i coped with same error and my suggestion are:

1. Start with try build another user in git lab
2. Recheck username & password (although it sounds obvious)
3. Validate the windows cerdential (start -> "cred")
4. Copy & paste same URL like you get from git lab, the struct should be:

http://{srvName}/{userInGitLab}/{Repository.git} no '/' at the end

5. Recheck the authorization in GitLab
6. Give an attention to case sensitive

Hope one of the above will solve it.

As per matplotlib's suggestion for image grids:

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import ImageGrid

fig = plt.figure(figsize=(4., 4.))
grid = ImageGrid(fig, 111,  # similar to subplot(111)
                 nrows_ncols=(2, 2),  # creates 2x2 grid of axes
                 axes_pad=0.1,  # pad between axes in inch.
                 )

for ax, im in zip(grid, image_data):
    # Iterating over the grid returns the Axes.
    ax.imshow(im)

plt.show()

var str1 = "150:05:05",
var str2 = "80:04:59";   

function compareTime(str1, str2){

    if(str1 === str2){
        return 0;
    }

    var time1 = str1.split(':');
    var time2 = str2.split(':');

    for (var i = 0; i < time1.length; i++) {
        if(time1[i] > time2[i]){
            return 1;
        } else if(time1[i] < time2[i]) {
            return -1;
        }
    }
}

Try keydown instead of keypress.

The keyboard events occur in this order: keydown, keyup, keypress

The problem with backspace probably is, that the browser will navigate back on keyup and thus your page will not see the keypress event.

You can rename a file using git's mv command:

$ git mv file_from file_to

Example:

$ git mv helo.txt hello.txt

$ git status
# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#   renamed:    helo.txt -> hello.txt
#

$ git commit -m "renamed helo.txt to hello.txt"
[master 14c8c4f] renamed helo.txt to hello.txt
 1 files changed, 0 insertions(+), 0 deletions(-)
 rename helo.txt => hello.txt (100%)

I usually do it this way whenever I need a date/time string:

set dt=%DATE:~6,4%_%DATE:~3,2%_%DATE:~0,2%__%TIME:~0,2%_%TIME:~3,2%_%TIME:~6,2%
set dt=%dt: =0%

This is for the German date/time format (dd.mm.yyyy hh:mm:ss). Basically I concatenate the substrings and finally replace all spaces with zeros.

Short explanation of how substrings work:

%VARIABLE:~num_chars_to_skip,num_chars_to_keep%

So to get just the year from a date like "29.03.2018" use:

%DATE:~6,4%
       ^-----skip 6 characters
         ^---keep 4 characters 

this is very old question, but since I came here while searching worth putting my answer.

SELECT DATEPART(ISO_WEEK,'2020-11-13') AS ISO_8601_WeekNr

To reload all sections, not just one with custom duration.

User duration parameter of UIView.animate to set custom duration.

UIView.animate(withDuration: 0.4, animations: { [weak self] in
    guard let `self` = self else { return }
    let indexSet = IndexSet(integersIn: 0..<self.tableView.numberOfSections)
    self.tableView.reloadSections(indexSet, with: UITableView.RowAnimation.fade)
})

You can easily restart your MySql service. This kicks the error off.

CSS Gallery has variety of Time Pickers. Have a look.

Perifer Design's time picker is similar to google one

Task method worked for me, except Browser.Task.IsCompleted has to be changed to PageLoaded.Task.IsCompleted.

Sorry I didnt add comment, that is because I need higher reputation to add comments.

Swift 2.0 Solution

You create a tap, pinch or swipe gesture recognizer in the same manor. Below I'll walk you through 4 steps to getting your recognizer up and running.

4 Steps

1.) Inherit from UIGestureRecognizerDelegate by adding it to your class signature.

class ViewController: UIViewController, UIGestureRecognizerDelegate {...}

2.) Control drag from your image to your viewController to create an IBOutlet:

@IBOutlet weak var tapView: UIImageView!

3.) In your viewDidLoad add the following code:

// create an instance of UITapGestureRecognizer and tell it to run 
// an action we'll call "handleTap:"
let tap = UITapGestureRecognizer(target: self, action: Selector("handleTap:"))
// we use our delegate
tap.delegate = self
// allow for user interaction
tapView.userInteractionEnabled = true
// add tap as a gestureRecognizer to tapView
tapView.addGestureRecognizer(tap)

4.) Create the function that will be called when your gesture recognizer is tapped. (You can exclude the = nil if you choose).

func handleTap(sender: UITapGestureRecognizer? = nil) {
    // just creating an alert to prove our tap worked!
    let tapAlert = UIAlertController(title: "hmmm...", message: "this actually worked?", preferredStyle: UIAlertControllerStyle.Alert)
    tapAlert.addAction(UIAlertAction(title: "OK", style: .Destructive, handler: nil))
    self.presentViewController(tapAlert, animated: true, completion: nil)
}

Your final code should look something like this:

class ViewController: UIViewController, UIGestureRecognizerDelegate {

    @IBOutlet weak var tapView: UIImageView!

    override func viewDidLoad() {
        super.viewDidLoad()

        let tap = UITapGestureRecognizer(target: self, action: Selector("handleTap:"))
        tap.delegate = self
        tapView.userInteractionEnabled = true
        tapView.addGestureRecognizer(tap)
    }

    func handleTap(sender: UITapGestureRecognizer? = nil) {
        let tapAlert = UIAlertController(title: "hmmm...", message: "this actually worked?", preferredStyle: UIAlertControllerStyle.Alert)
        tapAlert.addAction(UIAlertAction(title: "OK", style: .Destructive, handler: nil))
        self.presentViewController(tapAlert, animated: true, completion: nil)
    }
}

If this SQL is being used in any peoplesoft specific code (Application Engine, SQLEXEC, SQLfetch, etc..) you could use %Datein metaSQL. Peopletools automatically converts the date to a format which would be accepted by the database platform the application is running on.

In case this SQL is being used to perform a backend update from a query analyzer (like SQLDeveloper, SQLTools), the date format that is being used is wrong. Oracle expects the date format to be DD-MMM-YYYY, where MMM could be JAN, FEB, MAR, etc..

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

You may also write it like

{ this.state.banner && <div>{...}</div> }

If your state.banner is null or undefined, the right side of the condition is skipped.

You do it like this:

df = read.table("file.txt", nrows=1, header=TRUE, sep="\t", stringsAsFactors=FALSE)
colClasses = as.list(apply(df, 2, class))
needCols = c("Year", "Jan", "Feb", "Mar", "Apr", "May", "Jun")
colClasses[!names(colClasses) %in% needCols] = list(NULL)
df = read.table("file.txt", header=TRUE, colClasses=colClasses, sep="\t", stringsAsFactors=FALSE)

Use the pandas.DataFrame.rename funtion. Check this link for description.

data.rename(columns = {'gdp': 'log(gdp)'}, inplace = True)

If you intend to rename multiple columns then

data.rename(columns = {'gdp': 'log(gdp)', 'cap': 'log(cap)', ..}, inplace = True)

Apart from all the answers given, I would like to add few points :-

1) __repr__() is invoked when you simply write object's name on interactive python console and press enter.

2) __str__() is invoked when you use object with print statement.

3) In case, if __str__ is missing, then print and any function using str() invokes __repr__() of object.

4) __str__() of containers, when invoked will execute __repr__() method of its contained elements.

5) str() called within __str__() could potentially recurse without a base case, and error on maximum recursion depth.

6) __repr__() can call repr() which will attempt to avoid infinite recursion automatically, replacing an already represented object with ....

VirtualBox is a virtualizer, not an emulator. (The name kinda gives it away.) I.e. it can only virtualize a CPU that is actually there, not emulate one that isn't. In particular, VirtualBox can only virtualize x86 and AMD64 CPUs. iOS only runs on ARM CPUs.

For an iBeacon with ProximityUUID E2C56DB5-DFFB-48D2-B060-D0F5A71096E0, major 0, minor 0, and calibrated Tx Power of -59 RSSI, the transmitted BLE advertisement packet looks like this:

d6 be 89 8e 40 24 05 a2 17 6e 3d 71 02 01 1a 1a ff 4c 00 02 15 e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 00 00 00 00 c5 52 ab 8d 38 a5

This packet can be broken down as follows:

d6 be 89 8e # Access address for advertising data (this is always the same fixed value)
40 # Advertising Channel PDU Header byte 0.  Contains: (type = 0), (tx add = 1), (rx add = 0)
24 # Advertising Channel PDU Header byte 1.  Contains:  (length = total bytes of the advertising payload + 6 bytes for the BLE mac address.)
05 a2 17 6e 3d 71 # Bluetooth Mac address (note this is a spoofed address)
02 01 1a 1a ff 4c 00 02 15 e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 00 00 00 00 c5 # Bluetooth advertisement
52 ab 8d 38 a5 # checksum

The key part of that packet is the Bluetooth Advertisement, which can be broken down like this:

02 # Number of bytes that follow in first AD structure
01 # Flags AD type
1A # Flags value 0x1A = 000011010  
   bit 0 (OFF) LE Limited Discoverable Mode
   bit 1 (ON) LE General Discoverable Mode
   bit 2 (OFF) BR/EDR Not Supported
   bit 3 (ON) Simultaneous LE and BR/EDR to Same Device Capable (controller)
   bit 4 (ON) Simultaneous LE and BR/EDR to Same Device Capable (Host)
1A # Number of bytes that follow in second (and last) AD structure
FF # Manufacturer specific data AD type
4C 00 # Company identifier code (0x004C == Apple)
02 # Byte 0 of iBeacon advertisement indicator
15 # Byte 1 of iBeacon advertisement indicator
e2 c5 6d b5 df fb 48 d2 b0 60 d0 f5 a7 10 96 e0 # iBeacon proximity uuid
00 00 # major 
00 00 # minor 
c5 # The 2's complement of the calibrated Tx Power

Any Bluetooth LE device that can be configured to send a specific advertisement can generate the above packet. I have configured a Linux computer using Bluez to send this advertisement, and iOS7 devices running Apple's AirLocate test code pick it up as an iBeacon with the fields specified above. See: Use BlueZ Stack As A Peripheral (Advertiser)

This blog has full details about the reverse engineering process.

You can take a look here ( this is not a solution but the idea is here)

sample multi client with the google chat example

what you have to change/do :

• separate server and client logique in different classes

• for the client you need an object to manage one connect thread and on connected thread

• for the server you need an object to manage one listening thread per client, and one connected thread per client

• the server open a listening thread on each UUID (one per client)

• each client try to connect to each uuid (the uuid already taken will fail the connection => first come first served)

Any question ?

Here's a much cleaner solution for ES6 that I see isn't included here. It uses the Set and the spread operator: ...

var a = [1, 1, 2];

[... new Set(a)]

Which returns [1, 2]

Another approach is to wrap your table in a scrollable element and set the header cells to stick to the top.

The advantage of this approach is that you don't have to change the display on tbody and you can leave it to the browser to calculate column width while keeping the header cell widths in line with the data cell column widths.

Be aware that when you do press your <leader> key you have only 1000ms (by default) to enter the command following it.

This is exacerbated because there is no visual feedback (by default) that you have pressed your <leader> key and vim is awaiting the command; and so there is also no visual way to know when this time out has happened.

If you add set showcmd to your vimrc then you will see your <leader> key appear in the bottom right hand corner of vim (to the left of the cursor location) and perhaps more importantly you will see it disappear when the time out happens.

The length of the timeout can also be set in your vimrc, see :help timeoutlen for more information.

I agree with using events for this. Since I suspect that you're building an MDI-application (since you create many child forms) and creates windows dynamically and might not know when to unsubscribe from events, I would recommend that you take a look at Weak Event Patterns. Alas, this is only available for framework 3.0 and 3.5 but something similar can be implemented fairly easy with weak references.

However, if you want to find a control in a form based on the form's reference, it's not enough to simply look at the form's control collection. Since every control have it's own control collection, you will have to recurse through them all to find a specific control. You can do this with these two methods (which can be improved).

public static Control FindControl(Form form, string name)
{
    foreach (Control control in form.Controls)
    {
        Control result = FindControl(form, control, name);

        if (result != null)
            return result;
    }

    return null;
}

private static Control FindControl(Form form, Control control, string name)
{
    if (control.Name == name) {
        return control;
    }

    foreach (Control subControl in control.Controls)
    {
        Control result = FindControl(form, subControl, name);

        if (result != null)
            return result;
    }

    return null;
}

You may want to look into os dependent line separators, e.g.:

import os

with open('./output.txt', 'a') as f1:
    f1.write(content + os.linesep)

I'm using OS X 10.10, open the shell, type

export PATH=$PATH:/usr/local/mysql/bin

it works temporary.if you use Command+T to open a new tab ,mysql command will not work anymore.

We need to create a .bash_profile file to make it work each time you open a new tab.

nano ~/.bash_profile

add the following line to the file.

# Set architecture flags
export ARCHFLAGS="-arch x86_64"
# Ensure user-installed binaries take precedence
export PATH=/usr/local/mysql/bin:$PATH
# Load .bashrc if it exists
test -f ~/.bashrc && source ~/.bashrc

Save the file, then open a new shell tab, it works like a charm..

by the way, why not try https://github.com/dbcli/mycli

pip install -U mycli

it's a tool way better than the mysqlcli.. A command line client for MySQL that can do auto-completion and syntax highlighting

POSIX is a set of standards put forth by IEEE and The Open Group that describes how an ideal Unix would operate. Programmers, users, and administrators can all become familiar with the POSIX document, and expect a POSIX-complaint Unix to provide all of the standard facilities mentioned.

Since every Unix does things a little differently -- Solaris, Mac OS X, IRIX, BSD, and Linux all have their quirks -- POSIX is especially useful to those in the industry as it defines a standard environment to operate in. For example, most of the functions in the C library are based in POSIX; a programmer can, therefore, use one in his application and expect it to behave the same across most Unices.

However, the divergent areas of Unix are typically the focus, rather than the standard ones.

The great thing about POSIX is that you're welcome to read it yourself:

The Open Group Base Specifications Issue 7

Issue 7 is known as POSIX.1-2008, and there are new things in there -- however, Google-fu for POSIX.1 and such will allow you to see the entire history behind what Unix is.

Using android:singleLine="true" is deprecated.

Just add your input type and set maxline to 1 and everything will work fine

android:inputType="text"
android:maxLines="1"

Maybe using Where() before First() can help you, as my problem has been solved in this case.

var documentRow = _dsACL.Documents.Where(o => o.ID == id).FirstOrDefault();

String text = "In early March, the city of Topeka, Kansas," + "<br>" +
              "temporarily changed its name to Google..." + "<br>" + "<br>" +
              "...in an attempt to capture a spot" + "<br>" +
              "in Google's new broadband/fiber-optics project." + "<br>" + "<br>" +"<br>" +
              "source: http://en.wikipedia.org/wiki/Google_server#Oil_Tanker_Data_Center";
JLabel label = new JLabel("<html><div style='text-align: center;'>" + text + "</div></html>");

As far as the compiler is concerned, those two methods are identical. There will be one implementation of both.

This isn't a problem if the two methods are effectively identical, in that they should have the same implementation. If they are contractually different (as per the documentation for each interface), you'll be in trouble.

The two syntaxes are not equivalent and it can lead to unexpected errors. Here is a simple example showing the differences. If you have a model:

from django.db import models

class Test(models.Model):

    added = models.DateTimeField(auto_now_add=True)

And you create a first object:

foo = Test.objects.create(pk=1)

Then you try to create an object with the same primary key:

foo_duplicate = Test.objects.create(pk=1)
# returns the error:

You can use PSCP to copy files from Windows to Linux.

1. Download PSCP from putty.org
2. Open cmd in the directory with pscp.exe file

3. Type command pscp source_file user@host:destination_file

   • Ex.
     pscp sample.txt [email protected]:/mydata/sample.txt

Use

text-align: right

The text-align CSS property describes how inline content like text is aligned in its parent block element. text-align does not control the alignment of block elements itself, only their inline content.

See

text-align

<td class='alnright'>text to be aligned to right</td>

<style>
    .alnright { text-align: right; }
</style>

First define an Interface with the method you want to pass as a parameter

public interface Callable {
  public void call(int param);
}

Implement a class with the method

class Test implements Callable {
  public void call(int param) {
    System.out.println( param );
  }
}

// Invoke like that

Callable cmd = new Test();

This allows you to pass cmd as parameter and invoke the method call defined in the interface

public invoke( Callable callable ) {
  callable.call( 5 );
}

It's rather simple. Private setters allow you to create read-only public or protected properties.

That's it. That's the only reason.

Yes, you can create a read-only property by only specifying the getter, but with auto-implmeneted properties you are required to specify both get and set, so if you want an auto-implemented property to be read-only, you must use private setters. There is no other way to do it.

It's true that Private setters were not created specificlly for auto-implemented read-only properties, but their use is a bit more esoteric for other reasons, largely centering around read-only properties and the use of reflection and serialization.

SELECT cast(CAST([field_name] AS bigint) as nvarchar(255)) FROM table_name

In my case i wasn't exporting the module. module.exports = router;

The For-each loop, as it is called, is a type of for loop that is used with collections to guarantee that all items in a collection are iterated over. For example

for ( Object o : objects ) {
    System.out.println(o.toString());
}

Will call the toString() method on each object in the collection "objects". One nice thing about this is that you cannot get an out of bounds exception.

No, it's not possible in java.

You can do this way .. But try to avoid it.

String one, two, three;
one = two = three = "";

Would you be better off having just the one animation, but having it reverse?

animation-direction: reverse

This command:

iconv -f utf-8 -t utf-8 -c file.txt

will clean up your UTF-8 file, skipping all the invalid characters.

-f is the source format
-t the target format
-c skips any invalid sequence

Instead of using fake dates like 0000-00-00 00:00:00 or 0001-01-01 00:00:00 (the latter should be accepted as it is a valid date), change your database schema, to allow NULL values.

ALTER TABLE table_name MODIFY COLUMN date TIMESTAMP NULL

You may have used the filter function in the console which will hide anything that doesn't match your query. Remove the query and your messages will display.

Since this is tagged C# 4. With the open sourece framework ImpromptuIntereface it will use the dlr to call the constructor it is significantly faster than Activator when your constructor has arguments, and negligibly slower when it doesn't. However the main advantage is that it will handle constructors with C# 4.0 optional parameters correctly, something that Activator won't do.

protected T GetObject(params object[] args)
{
    return (T)Impromptu.InvokeConstructor(typeof(T), args);
}

The following link explains filters in Angular extremely well. It shows how it is possible to define custom sort logic within an ng-repeat. http://toddmotto.com/everything-about-custom-filters-in-angular-js

For sorting object with properties, this is the code I have used: (Note that this sort is the standard JavaScript sort method and not specific to angular) Column Name is the name of the property on which sorting is to be performed.

self.myArray.sort(function(itemA, itemB) {
    if (self.sortOrder === "ASC") {
        return itemA[columnName] > itemB[columnName];
    } else {
        return itemA[columnName] < itemB[columnName];
    }
});

Blob URLs (ref W3C, official name) or Object-URLs (ref. MDN and method name) are used with a Blob or a File object.

src="blob:https://crap.crap" I opened the blob url that was in src of video it gave a error and i can't open but was working with the src tag how it is possible?

Blob URLs can only be generated internally by the browser. URL.createObjectURL() will create a special reference to the Blob or File object which later can be released using URL.revokeObjectURL(). These URLs can only be used locally in the single instance of the browser and in the same session (ie. the life of the page/document).

What is blob url?
Why it is used?

Blob URL/Object URL is a pseudo protocol to allow Blob and File objects to be used as URL source for things like images, download links for binary data and so forth.

For example, you can not hand an Image object raw byte-data as it would not know what to do with it. It requires for example images (which are binary data) to be loaded via URLs. This applies to anything that require an URL as source. Instead of uploading the binary data, then serve it back via an URL it is better to use an extra local step to be able to access the data directly without going via a server.

It is also a better alternative to Data-URI which are strings encoded as Base-64. The problem with Data-URI is that each char takes two bytes in JavaScript. On top of that a 33% is added due to the Base-64 encoding. Blobs are pure binary byte-arrays which does not have any significant overhead as Data-URI does, which makes them faster and smaller to handle.

Can i make my own blob url on a server?

No, Blob URLs/Object URLs can only be made internally in the browser. You can make Blobs and get File object via the File Reader API, although BLOB just means Binary Large OBject and is stored as byte-arrays. A client can request the data to be sent as either ArrayBuffer or as a Blob. The server should send the data as pure binary data. Databases often uses Blob to describe binary objects as well, and in essence we are talking basically about byte-arrays.

if you have then Additional detail

You need to encapsulate the binary data as a BLOB object, then use URL.createObjectURL() to generate a local URL for it:

var blob = new Blob([arrayBufferWithPNG], {type: "image/png"}),
    url = URL.createObjectURL(blob),
    img = new Image();

img.onload = function() {
    URL.revokeObjectURL(this.src);     // clean-up memory
    document.body.appendChild(this);   // add image to DOM
}

img.src = url;                         // can now "stream" the bytes

Note that URL may be prefixed in webkit-browsers, so use:

var url = (URL || webkitURL).createObjectURL(...);

Instead just directly print the characters onto the console because the text file maybe very large and you may require a lot of memory.

#include <stdio.h>
#include <stdlib.h>

int main() {

    FILE *f;
    char c;
    f=fopen("test.txt","rt");

    while((c=fgetc(f))!=EOF){
        printf("%c",c);
    }

    fclose(f);
    return 0;
}

Similar to Lloyd's answer, but works with any size array.

$missing = array();
$missing[] = 'name';
$missing[] = 'zipcode';
$missing[] = 'phone';

if( is_array($missing) && count($missing) > 0 )
        {
            $result = '';
            $total = count($missing) - 1;
            for($i = 0; $i <= $total; $i++)
            { 
              if($i == $total && $total > 0)
                   $result .= "and ";

              $result .= $missing[$i];

              if($i < $total)
                $result .= ", ";
            }

            echo 'You need to provide your '.$result.'.';
            // Echos "You need to provide your name, zipcode, and phone."
        }

the settings below solved my issue

  "editor.detectIndentation": false,
  "editor.insertSpaces": false,
  "editor.tabSize": 2,

Try adding JSON.stringify(result) to convert the JS Object into a JSON string.

From your code I can see you are logging the result in error which is called if the AJAX request fails, so I'm not sure how you'd go about accessing the id/name/etc. then (you are checking for success inside the error condition!).

Note that if you use Chrome's console you should be able to browse through the object without having to stringify the JSON, which makes it easier to debug.

This is what may be happening, if the value of item.photo is undefined then item.photo != '' will always show as true. And if you think logically it actually makes sense, item.photo is not an empty string (so this condition comes true) since it is undefined.

Now for people who are trying to check if the value of input is empty or not in Angular 6, can go by this approach.

Lets say this is the input field -

<input type="number" id="myTextBox" name="myTextBox"_x000D_
 [(ngModel)]="response.myTextBox"_x000D_
            #myTextBox="ngModel">

To check if the field is empty or not this should be the script.

<div *ngIf="!myTextBox.value" style="color:red;">_x000D_
 Your field is empty_x000D_
</div>

Do note the subtle difference between the above answer and this answer. I have added an additional attribute .value after my input name myTextBox.
I don't know if the above answer worked for above version of Angular, but for Angular 6 this is how it should be done.

I got trouble to get it so I post pictures showing different options:

The execmgr.log will show the commandline and ccmcache folder used for installation. Typically, required apps don't show on appenforce.log and some clients will have outdated appenforce or no ppenforce.log files. execmgr.log also shows required hidden uninstall actions as well.

You may want to save the blog link. I still reference it from time to time.

ASP.NET grants access from the configuration file as a matter of precedence. In case of a potential conflict, the first occurring grant takes precedence. So,

deny user="?" 

denies access to the anonymous user. Then

allow users="dan,matthew" 

grants access to that user. Finally, it denies access to everyone. This shakes out as everyone except dan,matthew is denied access.

Edited to add: and as @Deviant points out, denying access to unauthenticated is pointless, since the last entry includes unauthenticated as well. A good blog entry discussing this topic can be found at: Guru Sarkar's Blog

Try this

html,
body {
  margin: 0;
  padding: 0;
  height: 100%;
}

Check the project properties. It's configurable there if you are using another .net windows application for example

In JavaScript, you can assign values to data attributes through Element.dataset.

For example:

avatar.dataset.id = 12345;

Reference: https://developer.mozilla.org/en/docs/Web/API/HTMLElement/dataset

Just for the sake of easy understanding you could follow this article: https://www.cs.utexas.edu/~scottm/cs307/handouts/deepCopying.htm

Shallow Copy:

Deep Copy:

Declare variable to assign value returned from setInterval(...) and pass the assigned variable to clearInterval();

e.g.

var timer, intervalInSec = 2;

timer = setInterval(func, intervalInSec*1000, 30 ); // third parameter is argument to called function 'func'

function func(param){
   console.log(param);
}

// Anywhere you've access to timer declared above call clearInterval

$('.htmlelement').click( function(){  // any event you want

       clearInterval(timer);// Stops or does the work
});

Your code is fine. Only the super was missing in the method :

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    // TODO add your menu : 
    inflater.inflate(R.menu.my_menu, menu);
    //TODO call super
    super.onCreateOptionsMenu(menu, inflater);
}

From the documentation:

We can add to a list in many ways:

assert [1,2] + 3 + [4,5] + 6 == [1, 2, 3, 4, 5, 6]
assert [1,2].plus(3).plus([4,5]).plus(6) == [1, 2, 3, 4, 5, 6]
    //equivalent method for +
def a= [1,2,3]; a += 4; a += [5,6]; assert a == [1,2,3,4,5,6]
assert [1, *[222, 333], 456] == [1, 222, 333, 456]
assert [ *[1,2,3] ] == [1,2,3]
assert [ 1, [2,3,[4,5],6], 7, [8,9] ].flatten() == [1, 2, 3, 4, 5, 6, 7, 8, 9]

def list= [1,2]
list.add(3) //alternative method name
list.addAll([5,4]) //alternative method name
assert list == [1,2,3,5,4]

list= [1,2]
list.add(1,3) //add 3 just before index 1
assert list == [1,3,2]
list.addAll(2,[5,4]) //add [5,4] just before index 2
assert list == [1,3,5,4,2]

list = ['a', 'b', 'z', 'e', 'u', 'v', 'g']
list[8] = 'x'
assert list == ['a', 'b', 'z', 'e', 'u', 'v', 'g', null, 'x']

You can also do:

def myNewList = myList << "fifth"

Something along the lines:

import os
if os.name == "posix":
    print(os.system("uname -a"))
# insert other possible OSes here
# ...
else:
    print("unknown OS")

My partial context looks like:

public partial class MyContext : DbContext
{
    public MyContext (string ConnectionString)
        : base(ConnectionString)
    {
        this.SetCommandTimeOut(300);
    }

    public void SetCommandTimeOut(int Timeout)
    {
        var objectContext = (this as IObjectContextAdapter).ObjectContext;
        objectContext.CommandTimeout = Timeout;
    }
}

I left SetCommandTimeOut public so only the routines I need to take a long time (more than 5 minutes) I modify instead of a global timeout.

Memory management in Linux is a bit tricky to understand, and I can't say I fully understand it yet, but I'll try to share a little bit of my experience and knowledge.

Short answer to your question: Yes there are other stuff included than whats in the list.

What's being shown in your list is applications run in userspace. The kernel uses memory for itself and modules, on top of that it also has a lower limit of free memory that you can't go under. When you've reached that level it will try to free up resources, and when it can't do that anymore, you end up with an OOM problem.

From the last line of your list you can read that the kernel reports a total-vm usage of: 1498536kB (1,5GB), where the total-vm includes both your physical RAM and swap space. You stated you don't have any swap but the kernel seems to think otherwise since your swap space is reported to be full (Total swap = 524284kB, Free swap = 0kB) and it reports a total vmem size of 1,5GB.

Another thing that can complicate things further is memory fragmentation. You can hit the OOM killer when the kernel tries to allocate lets say 4096kB of continous memory, but there are no free ones availible.

Now that alone probably won't help you solve the actual problem. I don't know if it's normal for your program to require that amount of memory, but I would recommend to try a static code analyzer like cppcheck to check for memory leaks or file descriptor leaks. You could also try to run it through Valgrind to get a bit more information out about memory usage.

Angular Material 10 now includes a new date range picker.

To use the new date range picker, you can use the mat-date-range-input and mat-date-range-picker components.

Example

HTML

<mat-form-field>
  <mat-label>Enter a date range</mat-label>
  <mat-date-range-input [rangePicker]="picker">
    <input matStartDate matInput placeholder="Start date">
    <input matEndDate matInput placeholder="End date">
  </mat-date-range-input>
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-date-range-picker #picker></mat-date-range-picker>
</mat-form-field>

You can read and learn more about this in their official documentation.

Unfortunately, they still haven't build a timepicker on this release.

To escape the backslash, simply use 2 of them, like this: \\

If you need to escape other things, this may be helpful..

I faced the same error when I used another class instead of component down the component decorator.

Component class must come just after the component decorator

  @Component({
 selector: 'app-smsgtrecon',
 templateUrl: './smsgtrecon.component.html',
 styleUrls: ['./smsgtrecon.component.css'],
 providers: [ChecklistDatabase]
 })


// THIS CAUSE ISSUE MOVE THIS UP TO COMPONENT DECORATOR
/**
* Node for to-do item
*/
 export class TodoItemNode {
 children: TodoItemNode[];
 item: string;
}


 export class SmsgtreconComponent implements OnInit {

After moving TodoItemNode to the top of component decorator it worked

Solution

// THIS CAUSE ISSUE MOVE THIS UP TO COMPONENT DECORATOR
/**
* Node for to-do item
*/
 export class TodoItemNode {
 children: TodoItemNode[];
 item: string;
}


@Component({
 selector: 'app-smsgtrecon',
 templateUrl: './smsgtrecon.component.html',
 styleUrls: ['./smsgtrecon.component.css'],
 providers: [ChecklistDatabase]
 })


 export class SmsgtreconComponent implements OnInit {

If you're going to use the preprocessor anyway, as per the other answers, then you can make the compiler determine the value of NUM_TYPES automagically:

#define NUM_TYPES (sizeof types / sizeof types[0])
static int types[] = { 
  1,
  2, 
  3, 
  4 };

To get selected item, you have to use SELECTEDITEM property of comboBox. And since this is an Object, if you wanna assign it to a string, you have to convert it to string, by using ToString() method:

string myItem = comboBox1.SelectedItem.ToString(); //this does the trick

• You can do this without installing anything into python itself.

• You don't need sudo or any privileges.

• You don't need to find the latest version of a virtualenv tar file

• You don't need to edit version info in a bash script to keep things up-to-date.

• You don't need curl/wget or tar installed, nor pip or easy_install

• this works for 2.7 as well as for 3.X

Save the following to /tmp/initvenv.py:

finally:
    shutil.rmtree(tmp_dir)  # always clean up

and use it as

python_binary_to_use_in_venv /tmp/initvenv.py your_venv_name [optional packages]

e.g. (if you really need the distribute compatibility layer for setuptools)

python /tmp/initvenv.py venv distribute

Please note that, with older python versions, this might give you InsecurePlatformWarnings¹.

Once you have your virtualenv (name e.g. venv) you can setup another virtualenv by using the virtualenv just installed:

venv/bin/virtualenv venv2

virtualenvwrapper

I recommend taking a look at virtualenvwrapper as well, after a one time setup:

% /opt/python/2.7.10/bin/python /tmp/initvenv.py venv virtualenvwrapper

and activation (can be done from your login script):

% source venv/bin/virtualenvwrapper.sh

you can do things like:

% mktmpenv 
New python executable in tmp-17bdc3054a46b2b/bin/python
Installing setuptools, pip, wheel...done.
This is a temporary environment. It will be deleted when you run 'deactivate'.
(tmp-17bdc3054a46b2b)% 

¹ _{I have not found a way to suppress the warning. It could be solved in pip and/or request, but the developers point to each other as the cause. I got the, often non-realistic, recommendation to upgrade the python version I was using to the latest version. I am sure this would break e.g my Linux Mint 17 install. Fortunately pip caches packages, so the Warning is made only once per package install.}

GitHub now supports closing a pull request

Basically, you need to do the following steps:

1. Visit the pull request page
2. Click on the pull request
3. Click the "close pull request" button

Example (button on the very bottom):

This way the pull request gets closed (and ignored), without merging it.

A character is anything that you can type such as letters,digits,punctuations and spaces. Strings appears in variables.i.e they are text items in perls. A character consist of 16bits. While the lenght of a string is unlimited.

Have a look at XPCOM, there might be something that you can use if Firefox 3 is used by a client.

Here, it is found at /mnt/shell/emulated/0

var results = {"id":"2231f87c-a62c-4c2c-8f5d-b76d11942301"}
console.log(results.id)
=>2231f87c-a62c-4c2c-8f5d-b76d11942301

results is now an object.

This works for me, and in this case was a remote connection: Note: The port was IMPORTANT for me

$dsn = "sqlsrv:Server=server.dyndns.biz,1433;Database=DBNAME";
$conn = new PDO($dsn, "root", "P4sw0rd");
$conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );

$sql = "SELECT * FROM Table";

foreach ($conn->query($sql) as $row) {
    print_r($row);
} 

There's no built in type for ConcurrentHashSet because you can always derive a set from a map. Since there are many types of maps, you use a method to produce a set from a given map (or map class).

Prior to Java 8, you produce a concurrent hash set backed by a concurrent hash map, by using Collections.newSetFromMap(map)

In Java 8 (pointed out by @Matt), you can get a concurrent hash set view via ConcurrentHashMap.newKeySet(). This is a bit simpler than the old newSetFromMap which required you to pass in an empty map object. But it is specific to ConcurrentHashMap.

Anyway, the Java designers could have created a new set interface every time a new map interface was created, but that pattern would be impossible to enforce when third parties create their own maps. It is better to have the static methods that derive new sets; that approach always works, even when you create your own map implementations.

Although not a merge per se, sometimes the entire contents of another file on another branch are needed. Jason Rudolph's blog post provides a simple way to copy files from one branch to another. Apply the technique as follows:

$ git checkout branch1 # ensure in branch1 is checked out and active
$ git checkout branch2 file.py

Now file.py is now in branch1.

Check out Pathname and in particular Pathname#exist?.

File and its FileTest module are perhaps simpler/more direct, but I find Pathname a nicer interface in general.

For disable trigger

You can't manipulate :after, because it's not technically part of the DOM and therefore is inaccessible by any JavaScript. But you can add a new class with a new :after specified.

    border-top-width: 22px;
    border-left-width: 22px;
    border-right-width: 22px;
}

JS:

$('.pageMenu .active').toggleClass('changed');

UPDATE: while it's impossible to directly modify the :after content, there are ways to read and/or override it using JavaScript. See "Manipulating CSS pseudo-elements using jQuery (e.g. :before and :after)" for a comprehensive list of techniques.

In case you want to add years to specific date besides today's date using either years, or months, or days. You can do the following

var christmas2000 = new Date(2000, 12, 25); 
christmas2000.setFullYear(christmas2000.getFullYear() + 5); // using year: next 5 years
christmas2000.setFullYear(christmas2000.getMonth() + 24); // using months: next 24 months
christmas2000.setFullYear(christmas2000.getDay() + 365); // using days: next 365 months

One method would be to use the array to initialize the vector

static const int arr[] = {16,2,77,29};
vector<int> vec (arr, arr + sizeof(arr) / sizeof(arr[0]) );

You can use simple jQuery jPut plugin

http://plugins.jquery.com/jput/

<script>
$(document).ready(function(){

var json = [{"name": "name1","email":"[email protected]"},{"name": "name2","link":"[email protected]"}];
//while running this code the template will be appended in your div with json data
$("#tbody").jPut({
    jsonData:json,
    //ajax_url:"youfile.json",  if you want to call from a json file
    name:"tbody_template",
});

});
</script>   

<table jput="t_template">
 <tbody jput="tbody_template">
     <tr>
         <td>{{name}}</td>
         <td>{{email}}</td>
     </tr>
 </tbody>
</table>

<table>
 <tbody id="tbody">
 </tbody>
</table>

Local variables are automatically freed when the function ends, you don't need to free them by yourself. You only free dynamically allocated memory (e.g using malloc) as it's allocated on the heap:

char *arr = malloc(3 * sizeof(char));
strcpy(arr, "bo");
// ...
free(arr);

I realize the following suggestion doesn't answer your question, but the simplest method I have found to capture a rapidly-changing DirectX view, is to plug a video camera into the S-video port of the video card, and record the images as a movie. Then transfer the video from the camera back to an MPG, WMV, AVI etc. file on the computer.

You can store it as a JSON string in a constant. And application point of view, JSON can be useful in other cases.

define ("FRUITS", json_encode(array ("apple", "cherry", "banana")));    
$fruits = json_decode (FRUITS);    
var_dump($fruits);

File.GetLastWriteTime to Get last modified

File.CreationTime to get Created time

The best solution to this in my opinion is this:

1. Create a custom filter which can be in a common.module.js file for example - used through out your app:

   var app = angular.module('common.module', []);
   
   // html filter (render text as html)
   app.filter('html', ['$sce', function ($sce) { 
       return function (text) {
           return $sce.trustAsHtml(text);
       };    
   }])
   

2. Usage:

   <span ng-bind-html="yourDataValue | html"></span>
   

Now - I don't see why the directive ng-bind-html does not trustAsHtml as part of its function - seems a bit daft to me that it doesn't

Anyway - that's the way I do it - 67% of the time, it works ever time.

This is what I do for Jupyter/Anaconda on Windows. This method also passes jupyter a python configuration script. I use this to add a path to my project parent folder:

1 Create jnote.bat somewhere:

@echo off
call activate %1
call jupyter notebook "%CD%" %2 %3
pause

In the same folder create a windows shortcut jupyter-notebook

        TARGET: D:\util\jnote.bat py3-jupyter --config=jupyter_notebook_config.py
        START IN: %CD%

Add the jupyter icon to the shortcut.

2 In your jupyter projects folders(s) do the following:

Create jupyter_notebook_config.py, put what you like in here:

import os
import sys
import inspect

# Add parent folder to sys path

currentdir = os.path.dirname(os.path.abspath(
    inspect.getfile(inspect.currentframe())))

parentdir = os.path.dirname(currentdir)

os.environ['PYTHONPATH'] = parentdir

Then paste the jupyter-notebook shortcut. Double-click the shortcut and your jupyter should light up and the packages in the parent folder will be available.

Using Python to extract a value from the provided Json

Working sample:-

import json
import sys

//load the data into an element
data={"test1" : "1", "test2" : "2", "test3" : "3"}

//dumps the json object into an element
json_str = json.dumps(data)

//load the json to a string
resp = json.loads(json_str)

//print the resp
print (resp)

//extract an element in the response
print (resp['test1'])

As already pointed out by Nico Huysamen, finding multiple mode in Java 1.8 can be done alternatively as below.

import java.util.ArrayList;
import java.util.List;
import java.util.HashMap;
import java.util.Map;

public static void mode(List<Integer> numArr) {
    Map<Integer, Integer> freq = new HashMap<Integer, Integer>();;
    Map<Integer, List<Integer>> mode = new HashMap<Integer, List<Integer>>();

    int modeFreq = 1; //record the highest frequence
    for(int x=0; x<numArr.size(); x++) { //1st for loop to record mode
        Integer curr = numArr.get(x); //O(1)
        freq.merge(curr, 1, (a, b) -> a + b); //increment the frequency for existing element, O(1)
        int currFreq = freq.get(curr); //get frequency for current element, O(1)

        //lazy instantiate a list if no existing list, then
        //record mapping of frequency to element (frequency, element), overall O(1)
        mode.computeIfAbsent(currFreq, k -> new ArrayList<>()).add(curr);

        if(modeFreq < currFreq) modeFreq = currFreq; //update highest frequency
    }
    mode.get(modeFreq).forEach(x -> System.out.println("Mode = " + x)); //pretty print the result //another for loop to return result
}

Happy coding!

A TreeMap is always sorted by the keys, anything else is impossible. A Comparator merely allows you to control how the keys are sorted.

If you want the sorted values, you have to extract them into a List and sort that.

If you know that the values are strings, you can call the replace method on them while in the cycle: this way you will change the value.

Altohugh this is limited to the case in which the values are strings and hence doesn't answer the question fully, I thought it can be useful to someone.

@DSM's answer is perfectly fine in almost any normal scenario. But if you're the type of programmer who wants to go a little deeper than the surface level, you might be interested to know that it is a little faster to call numpy functions on the underlying .to_numpy() (or .values for <0.24) array instead of directly calling the (cythonized) functions defined on the DataFrame/Series objects.

For example, you can use ndarray.max() along the first axis.

# Data borrowed from @DSM's post.
df = pd.DataFrame({"A": [1,2,3], "B": [-2, 8, 1]})
df
   A  B
0  1 -2
1  2  8
2  3  1

df['C'] = df[['A', 'B']].values.max(1)
# Or, assuming "A" and "B" are the only columns, 
# df['C'] = df.values.max(1) 
df

   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3 

If your data has NaNs, you will need numpy.nanmax:

df['C'] = np.nanmax(df.values, axis=1)
df

   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3 

You can also use numpy.maximum.reduce. numpy.maximum is a ufunc (Universal Function), and every ufunc has a reduce:

df['C'] = np.maximum.reduce(df['A', 'B']].values, axis=1)
# df['C'] = np.maximum.reduce(df[['A', 'B']], axis=1)
# df['C'] = np.maximum.reduce(df, axis=1)
df

   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3

np.maximum.reduce and np.max appear to be more or less the same (for most normal sized DataFrames)—and happen to be a shade faster than DataFrame.max. I imagine this difference roughly remains constant, and is due to internal overhead (indexing alignment, handling NaNs, etc).

The graph was generated using perfplot. Benchmarking code, for reference:

import pandas as pd
import perfplot

np.random.seed(0)
df_ = pd.DataFrame(np.random.randn(5, 1000))

perfplot.show(
    setup=lambda n: pd.concat([df_] * n, ignore_index=True),
    kernels=[
        lambda df: df.assign(new=df.max(axis=1)),
        lambda df: df.assign(new=df.values.max(1)),
        lambda df: df.assign(new=np.nanmax(df.values, axis=1)),
        lambda df: df.assign(new=np.maximum.reduce(df.values, axis=1)),
    ],
    labels=['df.max', 'np.max', 'np.maximum.reduce', 'np.nanmax'],
    n_range=[2**k for k in range(0, 15)],
    xlabel='N (* len(df))',
    logx=True,
    logy=True)
