JetBrains has a .gitignore_global on GitHub.

The last 9 elements can be read from left to right using numlist[-9:], or from right to left using numlist[:-10:-1], as you want.

>>> a=range(17)
>>> print a
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16]
>>> print a[-9:]
[8, 9, 10, 11, 12, 13, 14, 15, 16]
>>> print a[:-10:-1]
[16, 15, 14, 13, 12, 11, 10, 9, 8]

Below command worked for me.

redis-cli -h redis_host_url KEYS "*abcd*" | xargs redis-cli -h redis_host_url DEL

The ProGit book has a very good explanation:

Tracking Branches

Checking out a local branch from a remote branch automatically creates what is called a tracking branch. Tracking branches are local branches that have a direct relationship to a remote branch. If you’re on a tracking branch and type git push, Git automatically knows which server and branch to push to. Also, running git pull while on one of these branches fetches all the remote references and then automatically merges in the corresponding remote branch.

When you clone a repository, it generally automatically creates a master branch that tracks origin/master. That’s why git push and git pull work out of the box with no other arguments. However, you can set up other tracking branches if you wish — ones that don’t track branches on origin and don’t track the master branch. The simple case is the example you just saw, running git checkout -b [branch] [remotename]/[branch]. If you have Git version 1.6.2 or later, you can also use the --track shorthand:

$ git checkout --track origin/serverfix
Branch serverfix set up to track remote branch refs/remotes/origin/serverfix.
Switched to a new branch "serverfix"

To set up a local branch with a different name than the remote branch, you can easily use the first version with a different local branch name:

$ git checkout -b sf origin/serverfix
Branch sf set up to track remote branch refs/remotes/origin/serverfix.
Switched to a new branch "sf"

Now, your local branch sf will automatically push to and pull from origin/serverfix.

BONUS: extra git status info

With a tracking branch, git status will tell you whether how far behind your tracking branch you are - useful to remind you that you haven't pushed your changes yet! It looks like this:

$ git status
On branch master
Your branch is ahead of 'origin/master' by 1 commit.
  (use "git push" to publish your local commits)

or

$ git status
On branch dev
Your branch and 'origin/dev' have diverged,
and have 3 and 1 different commits each, respectively.
  (use "git pull" to merge the remote branch into yours)

If you are calling from within Stored Procedure don't use @. In my case it returns 0

CALL SP_NAME(L_OUTPUT_PARAM)

Cern's ROOT produces some pretty nice stuff, I use it to display Neural Network data a lot.

I would probably use something like this:

function generatePassword() {
    var length = 8,
        charset = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789",
        retVal = "";
    for (var i = 0, n = charset.length; i < length; ++i) {
        retVal += charset.charAt(Math.floor(Math.random() * n));
    }
    return retVal;
}

That can then be extended to have the length and charset passed by a parameter.

I added some codes and save .class file.

What you see in JD EClipse Decompiler is decompiled representation of byte code in the .class file. Even though you change the text it won't affect the byte code.

also happens when you use jinja templates (which have different syntax for calling object methods) and you forget to set it in settings.py

as.character() would be the general way rather than use paste() for its side effect

> v <- 20081101
> date <- as.Date(as.character(v), format = "%Y%m%d")
> date
[1] "2008-11-01"

(I presume this is a simple example and something like this:

v <- "20081101"

isn't possible?)

Thanks to @IanRoberts, I had to use the normalize-space function on my nodes to check if they were empty.

<xsl:if test="((node/ABC!='') and (normalize-space(node/DEF)='') and (normalize-space(node/GHI)=''))">
  This worked perfectly fine.
</xsl:if>

The DateTime object has a Property which returns only the date portion of the value.

    public static void Main()
{
    System.DateTime _Now = DateAndTime.Now;
    Console.WriteLine("The Date and Time is " + _Now);
    //will return the date and time
    Console.WriteLine("The Date Only is " + _Now.Date);
    //will return only the date
    Console.Write("Press any key to continue . . . ");
    Console.ReadKey(true);
}

The easiest way would be

Section = 'Sec_' + Section

But for efficiency, see: https://waymoot.org/home/python_string/

NSArray *directoryPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory,NSUserDomainMask,YES);
NSString *imagePath =  [directoryPath objectAtIndex:0];
//If you have superate folder
imagePath= [imagePath stringByAppendingPathComponent:@"ImagesFolder"];//Get docs dir path with folder name
_imageName = [_imageName stringByAppendingString:@".jpg"];//Assign image name
imagePath= [imagePath stringByAppendingPathComponent:_imageName];
NSLog(@"%@", imagePath);

//Method 1:
BOOL file = [[NSFileManager defaultManager] fileExistsAtPath: imagePath];
if (file == NO){
    NSLog("File not exist");
} else {
    NSLog("File exist");
}

//Method 2:
NSData *data = [NSData dataWithContentsOfFile:imagePath];
UIImage *image = [UIImage imageWithData:data];
if (!(image == nil)) {//Check image exist or not
    cell.photoImageView.image = image;//Display image
}

I think you should try with this API

Create a quick export from a database table into Excel

Compile some statistical records with a few calculations and deliver
the result in an Excel worksheet

Gather the items off your (web-based) todo list, put them in a
worksheet and use it as a foundation for some more statistics
magic.**

If you want a query to use currently selected database. simply copy paste this query. (No modification required)

SELECT table_name ,
  round(((data_length + index_length) / 1024 / 1024), 2) as SIZE_MB
FROM information_schema.TABLES
WHERE table_schema = DATABASE() ORDER BY SIZE_MB DESC;

How things change in a year. In addition to the header attribute in place of xhr.setRequestHeader, current jQuery (1.7.2+) includes a username and password attribute with the $.ajax call.

$.ajax
({
  type: "GET",
  url: "index1.php",
  dataType: 'json',
  username: username,
  password: password,
  data: '{ "comment" }',
  success: function (){
    alert('Thanks for your comment!'); 
  }
});

EDIT from comments and other answers: To be clear - in order to preemptively send authentication without a 401 Unauthorized response, instead of setRequestHeader (pre -1.7) use 'headers':

$.ajax
({
  type: "GET",
  url: "index1.php",
  dataType: 'json',
  headers: {
    "Authorization": "Basic " + btoa(USERNAME + ":" + PASSWORD)
  },
  data: '{ "comment" }',
  success: function (){
    alert('Thanks for your comment!'); 
  }
});

The quoting rules are painful. I think you want:

SELECT nextval('foo."SQ_ID"');

to prevent case-folding of SQ_ID.

Try:

printf("%04x",a);

• 0 - Left-pads the number with zeroes (0) instead of spaces, where padding is specified.
• 4 (width) - Minimum number of characters to be printed. If the value to be printed is shorter than this number, the result is right justified within this width by padding on the left with the pad character. By default this is a blank space, but the leading zero we used specifies a zero as the pad char. The value is not truncated even if the result is larger.
• x - Specifier for hexadecimal integer.

More here

>>> bits_in_word=12
>>> int('111111111111',2)-(1<<bits_in_word)
-1

This works because:

The two's complement of a binary number is defined as the value obtained by subtracting the number from a large power of two (specifically, from 2^N for an N-bit two's complement). The two's complement of the number then behaves like the negative of the original number in most arithmetic, and it can coexist with positive numbers in a natural way.

Correct answer is: $("#selElement_Id option:selected").removeAttr("selected");

Towards the second half of Create REST API using ASP.NET MVC that speaks both JSON and plain XML, to quote:

Now we need to accept JSON and XML payload, delivered via HTTP POST. Sometimes your client might want to upload a collection of objects in one shot for batch processing. So, they can upload objects using either JSON or XML format. There's no native support in ASP.NET MVC to automatically parse posted JSON or XML and automatically map to Action parameters. So, I wrote a filter that does it."

He then implements an action filter that maps the JSON to C# objects with code shown.

In Haskell:

filter ((==) 12345 . sum) $ subsequences [1,5,22,15,0,..]

And J:

(]#~12345=+/@>)(]<@#~[:#:@i.2^#)1 5 22 15 0 ...

As you may notice, both take the same approach and divide the problem into two parts: generate each member of the power set, and check each member's sum to the target.

There are other solutions but this is the most straightforward.

Do you need help with either one, or finding a different approach?

To disable all previous dates, give start date as today date

startDate: new Date()

Solution: disable all previous dates from today

$(function() {_x000D_
    $( "#datepicker" ).datepicker({ startDate: new Date()});_x000D_
 });

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<link href="https://cdnjs.cloudflare.com/ajax/libs/datepicker/0.6.5/datepicker.min.css" rel="stylesheet"/>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/datepicker/0.6.5/datepicker.min.js"></script>_x000D_
_x000D_
<div> Select Date <input type="text" id="datepicker" /></div>

Solution: disable all past dates from a particular date.

$(function() {_x000D_
    $( "#datepicker" ).datepicker({ startDate: new Date("2019-10-15")});_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<link href="https://cdnjs.cloudflare.com/ajax/libs/datepicker/0.6.5/datepicker.min.css" rel="stylesheet"/>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/datepicker/0.6.5/datepicker.min.js"></script>_x000D_
_x000D_
<div> Select Date <input type="text" id="datepicker" /></div>

This will disable all days before the date 15th October 2019 (2019-10-15)

My comment might not be relevant to the tags given. However, I was lead to this page from my search. I was looking for similar check in R and I came up the following with the help of @hugovdbeg post. I hope it would be helpful for someone who is looking for similar solution in R

'USERNAME' %in% names(Sys.getenv())

To get the convenient list of tables on the left panel below each database you have to click the tiny icon on the top right of the left panel. At least in MySQL Workbench 6.3 CE on Win7 this worked to get the full list of tables.

See my screenshot to explain.

Sadly this icon not even has a mouseover title attribute, so it was a lucky guess that I found it.

The #define allows you to establish a value in a header that would otherwise compile to size-greater-than-zero. Your headers should not compile to size-greater-than-zero.

// File:  MyFile.h

// This header will compile to size-zero.
#define TAX_RATE 0.625

// NO:  static const double TAX_RATE = 0.625;
// NO:  extern const double TAX_RATE;  // WHAT IS THE VALUE?

EDIT: As Neil points out in the comment to this post, the explicit definition-with-value in the header would work for C++, but not C.

Depends on if the form that the select is contained in has the method set to "get" or "post".

If <form method="get"> then the value of the select will be located in the super global array $_GET['taskOption'].

If <form method="post"> then the value of the select will be located in the super global array $_POST['taskOption'].

To store it into a variable you would:

$option = $_POST['taskOption']

A good place for more information would be the PHP manual: http://php.net/manual/en/tutorial.forms.php

As specified in oracle official tutorial , it states that:

If a client can reasonably be expected to recover from an exception, make it a checked exception. If a client cannot do anything to recover from the exception, make it an unchecked exception.

If I have an Application interacting with database using JDBC , And I have a method that takes the argument as the int item and double price. The price for corresponding item is read from database table. I simply multiply the total number of item purchased with the price value and return the result. Although I am always sure at my end(Application end) that price field value in the table could never be negative .But what if the price value comes out negative? It shows that there is a serious issue with the database side. Perhaps wrong price entry by the operator. This is the kind of issue that the other part of application calling that method can't anticipate and can't recover from it. It is a BUG in your database. So , and IllegalArguementException() should be thrown in this case which would state that the price can't be negative.
I hope that I have expressed my point clearly..

I was looking for this too. I've got a project that runs HWC, and I'd like to keep the web site out of the app tree, but I don't want to keep it in the debug (or release) directory. FWIW, the accepted solution (and this one as well) only identifies the directory the executable is running in.

To find that directory, I've been using

string startupPath = System.IO.Path.GetFullPath(".\\").

This happens because you put bracket of return on the next line. That might be a common mistake if you write js without semicolons and use a style where you put opened braces on the next line.

Interpreter thinks that you return undefined and doesn't check your next line. That's the return operator thing.

Put your opened bracket on the same line with the return.

A really fast way to solve this problem is to make a database link from the Oracle database to the MySQL database. You can create database links to non-Oracle databases. After you have created the database link you can retrieve your data from the MySQL database with a ... create table mydata as select * from ... statement. This is called heterogeneous connectivity. This way you don't have to do anything in your .net application to move the data.

Another way is to use ODP.NET. In ODP.NET you can use the OracleBulkCopy-class.

But I don't think that inserting 160k records in an Oracle table with System.Data.OracleClient should take 25 minutes. I think you commit too many times. And do you bind your values to the insert statement with parameters or do you concatenate your values. Binding is much faster.

           @Html.RadioButton("Insured.GenderType", 1, (Model.Insured.GenderType == 1 ))
           @Web.Mvc.Claims.Resources.PartyResource.MaleLabel
           @Html.RadioButton("Insured.GenderType", 2, Model.Insured.GenderType == 2)
           @Web.Mvc.Claims.Resources.PartyResource.FemaleLabel

"aoColumnDefs" : [   
{
  'bSortable' : false,  
  'aTargets' : [ 0 ]
}]

Here 0 is the index of the column, if you want multiple columns to be not sorted, mention column index values seperated by comma(,)

You can also create a borderless window, and make the borders and title bar yourself

hostname -I | awk ' {print $1}'

I had the same issue. Changing

$.ajax(...)

to

jQuery.ajax(...)

did not work. But then I found that jQuery was included twice and removing one of them fixed the problem.

Note the tilda that reverses the selection. It uses pandas methods (i.e. is faster than if/else).

df.loc[(df['c1'] == 'Value'), 'c2'] = 10
df.loc[~(df['c1'] == 'Value'), 'c2'] = df['c3']

id is the method you want to use: to convert it to hex:

hex(id(variable_here))

For instance:

x = 4
print hex(id(x))

Gave me:

0x9cf10c

Which is what you want, right?

(Fun fact, binding two variables to the same int may result in the same memory address being used.)
Try:

x = 4
y = 4
w = 9999
v = 9999
a = 12345678
b = 12345678
print hex(id(x))
print hex(id(y))
print hex(id(w))
print hex(id(v))
print hex(id(a))
print hex(id(b))

This gave me identical pairs, even for the large integers.

I've faked readonly on a radio button by disabling only the un-checked radio buttons. It keeps the user from selecting a different value, and the checked value will always post on submit.

Using jQuery to make readonly:

$(':radio:not(:checked)').attr('disabled', true);

This approach also worked for making a select list readonly, except that you'll need to disable each un-selected option.

This dplyr method works nicely when piping.

For selected columns:

library(dplyr)
iris %>% 
  select(Sepal.Width, Species) %>% 
  t %>% c %>% unique

CSS rules are inherited by default - hence the "cascading" name. To get what you want you need to use !important:

form div
{
    font-size: 12px;
    font-weight: bold;
}

div.content
{
    // any rule you want here, followed by !important
}

Send the data from the form:

$("#change_section_type").live "change", ->
url = $(this).attr("data-url")
postData = $(this).parents("#contract_setting_form").serializeArray()
$.ajax
  type: "PUT"
  url: url
  dataType: "script"
  data: postData

If example is not final then a simple reassignment would work:

example = new String[example.length];

This assumes you need the array to remain the same size. If that's not necessary then create an empty array:

example = new String[0];

If it is final then you could null out all the elements:

Arrays.fill( example, null );

• See: void Arrays#fill(Object[], Object)
• Consider using an ArrayList or similar collection

I am a beginner so here is a beginners answer. The if in the for loop gives i which can then be used however needed such as Numbers[i] in another vector. Most is fluff for examples sake, the for/if really says it all.

int main(){
vector<string>names{"Sara", "Harold", "Frank", "Taylor", "Sasha", "Seymore"};
string req_name;
cout<<"Enter search name: "<<'\n';
cin>>req_name;
    for(int i=0; i<=names.size()-1; ++i) {
        if(names[i]==req_name){
            cout<<"The index number for "<<req_name<<" is "<<i<<'\n';
            return 0;
        }
        else if(names[i]!=req_name && i==names.size()-1) {
            cout<<"That name is not an element in this vector"<<'\n';
        } else {
            continue;
        }
    }

Dictionaries in python have no order. You could use a list of tuples as your data structure instead.

d = { 'a': 10, 'b': 20, 'c': 30}
newd = [('a',10), ('b',20), ('c',30)]

Then this code could be used to find the locations of keys with a specific value

locations = [i for i, t in enumerate(newd) if t[0]=='b']

>>> [1]

The suggested causes are now proven to be mostly impossible. I'm running SSMS V17.9.2 against SS 2014 and still have the problem. Memory problems have existed with this tool since at least 2006 when I started using SSMS.

Yes, MS 'wants' to get rid of diagramming but users won't let them. I have a feeling they will never fix any of these issues because they want users to be so fed up with the tool that enough of them quit using it and they can abandon it entirely.

Restarting is still a workaround if you can stand doing so numerous times per day.

Postgres started on Linux/Unix. I suspect that reversing the slash with fix it.

If you need to fully qualify something

\i c:/somedir/script2.sql

If that doesn't fix it, my next guess would be you need to escape the backslash.

\i somedir\\script2.sql

When you use a function ...

<p onclick="update_url('/en/step2');">Link</p>

<script>
function update_url(url) {
    history.pushState(null, null, url);
}
</script>

Change your positioning a bit:

.container {
    border: 1px solid #DDDDDD;
    width: 200px;
    height: 200px;
    position:relative;
}
.tag {
    float: left;
    position: absolute;
    left: 0px;
    top: 0px;
    background-color: green;
}

jsFiddle example

You need to set relative positioning on the container and then absolute on the inner tag div. The inner tag's absolute positioning will be with respect to the outer relatively positioned div. You don't even need the z-index rule on the tag div.

To prevent duplication in memory, resharper is suggesting this:

List<string> myList = new List<string>();
IEnumerable<string> myEnumerable = myList;
List<string> listAgain = myList as List<string>() ?? myEnumerable.ToList();

.ToList() returns a new immutable list. So changes to listAgain does not effect myList in @Tamas Czinege answer. This is correct in most instances for least two reasons: This helps prevent changes in one area effecting the other area (loose coupling), and it is very readable, since we shouldn't be designing code with compiler concerns.

But there are certain instances, like being in a tight loop or working on an embedded or low memory system, where compiler considerations should be taken into consideration.

Download the file and from the same directory run docker build -t nodebb .

This will give you an image on your local machine that's named nodebb that you can launch an container from with docker run -d nodebb (you can change nodebb to your own name).

1. To properly purge the queue of waiting tasks you have to stop all the workers (http://celery.readthedocs.io/en/latest/faq.html#i-ve-purged-messages-but-there-are-still-messages-left-in-the-queue):

$ sudo rabbitmqctl stop

or (in case RabbitMQ/message broker is managed by Supervisor):

$ sudo supervisorctl stop all

2. ...and then purge the tasks from a specific queue:

$ cd <source_dir>
$ celery amqp queue.purge <queue name>

3. Start RabbitMQ:

$ sudo rabbitmqctl start

or (in case RabbitMQ is managed by Supervisor):

$ sudo supervisorctl start all

Another Ionic way. Using this ion-buttons tag, and the right keyword puts all the buttons in this group to the right. I made some custom toggle buttons that i wanted on one line, but the group to be right justified.

Because I just went through this - I wanted to give my solution even though this is a bit old.

I have several computers on a home router and I have been working on some projects for myself. Well, I wanted to see what it looked like on my mobil devices. But WAMP was set so I could only get on from the development system. So I began looking around and found this article as well as some others. The problem is - none of them worked for me. So I was left to figure this out on my own.

My solution:

First, in the HTTPD.CONF file you need to add one line to the end of the list of what devices are allowed to access your WAMP server. So instead of:

#    Require all granted
#   onlineoffline tag - don't remove
     Order Deny,Allow
     Deny from all
     Allow from 127.0.0.1
     Allow from ::1
     Allow from localhost

make it:

#    Require all granted
#   onlineoffline tag - don't remove
     Order Deny,Allow
     Deny from all
     Allow from 127.0.0.1
     Allow from ::1
     Allow from localhost
     Allow from 192.168.78

The above says that any device that is on your router (the '78' is just an arbitrary number picked for this solution. It should be whatever your router is set up for. So it might be 192.168.1 or 192.168.0 or even 192.168.254 - you have to look it up on your router.) can now access your server.

The above did NOT do anything for me - at first. There is more you need to do. But first - what you do NOT need to do. You do NOT need to change the WAMP setting from Offline to Online. FOR ME - changing that setting doesn't do anything. Unknown why - it just doesn't. So change it if you want - but I don't think it needs to be changed.

So what else DOES need to be changed? You have to go all the way back to the beginning of the httpd.conf file for this next change and it is really simple. You have to add a new line after the

Listen Localhost:80

add

Listen 192.168.78.###:80

Where the "###" is what IP your server is on. So let's say your server is on IP number 234. Then the above command would become

Listen localhost:80
Listen 192.168.78.234:80

Again - the '78' is just an arbitrary number I picked. To get your real IP number you have to open a command window and type in

ipconfig/all

command. Look for what your TCP/IPv4 number is and set it to that number or TCP/IPv6 if that is all you have (although on internal router sets you usually have an IPv4 number).

Note: In case you do not know how to bring up a command window - you click on Start, select the "Run" option, and type "cmd.exe" in to the dialog box without the quotes. On newer systems (since they keep changing everything) it might be the white windows icon or the circle or Bill Gates jumping up and down. Whatever it is - click on it.

Once you have done the above - restart all services and everything should come up just fine.

Finally - why? Why do you have to change the Listen command? It has to do with localhost. 'localhost' is set to 127.0.0.1 and NOT your IP address by default. This can be found in your host file which is usually found in the system32 folder under Windows but probably has been moved by Microsoft to somewhere else. Look it up online for where it is and go look at it. If you see a lot of sex, porn, etc sites in your localhost host file - you need to get rid of them (unless that is your thing). I suggest RogueKiller (at AdLice.com) be used to take a look at your system because it can reset your host file for you.

If your host file is normal though - it should contain just one entry and that entry is to set localhost to 127.0.0.1. That is why using localhost in the httpd.conf file makes it so you only can work on everything and see everything from your server computer.

So if you feel adventurous - change your host file and leave the Listen command alone OR just change the Listen command to listen to port 80 on your server.

NEW (I forgot to put in this part)

You MAY have to change your TCP/IP address. (Mine is already set up so I didn't need to do this.) You will need to look up for your OS how to get to where your TCP/IP address is defined. Under Windows XP this was Control Panel->Network Connections. This has changed in later OSs so you have to look up how to get there. Anyway, once there you will see your Wireless Network Connection or Local Area Connection (Windows). Basically WIFI or Ethernet cable. Select the one that is active and in use. Under Windows you then right-click and select Properties. A dialog should pop-up and you should see a list of checkboxes with what they are to the side. Look for the one that is for TCP/IP. There should be one that says TCP/IP v4. Select it. (If there isn't one - you should proceed with caution.) Click the Properties button and you should get another dialog box. This one shows either "Obtain an IP address automatically" or "Use the following IP address" selected. If it is the first one then you have to change it to the second one. BUT BEFORE YOU DO THAT - bring up a command window and type in the ipcongfig/all command so you have, right there in front of you, what your default gateway is. Then change it from "Obtain..." to "Use...". Where it says "IP address" put in the IP address you want to always use. This is the IP address you put in on the Listen command above. The second line (Subnet mask) usually is 255.255.255.0 meaning only the last number (ie: 0) changes. Then, looking back at the command window put in your default gateway. Last, but not least, when you changed from "Obtain..." to "Use..." the DNS settings may have changed. If the section which deals with DNS settings has changed to "Use..." and it is blank - the answer is simple. Just look at that ipconfig/all output, find the DNS setting(s) there and put them in to the fields provided. Once done click the OK button and then click the second OK button. Once the dialog closes you may have to reboot your system for the changes to take effect. Try it out by going to Google or Stack Overflow. If you can still go places - then no reboot is required. Otherwise, reboot. Remember! If you can't get on the internet afterwards all you do is go back and reset everything to the "Obtain..." option. The most likely reason, after making the changes, that you can no longer get on the internet is because the TCP/IP address you chose to use is already in use by the router. The saying "There can be only one" goes for TCP/IP addresses too. This is why I always pick a high one-hundreds number or a low two-hundreds number. Because most DHCP set ups use numbers less than fifty. So in this way you don't collide with someone else's TCP/IP number.

This is how I fixed my problem.

Alternative way:

std::string s = "This is an STL string";
QString qs = QString::fromAscii(s.data(), s.size());

This has the advantage of not using .c_str() which might cause the std::string to copy itself in case there is no place to add the '\0' at the end.

ConcurrentLinkedQueue

If you don't care about having index-based access and just want the insertion-order-preserving characteristics of a List, you could consider a java.util.concurrent.ConcurrentLinkedQueue. Since it implements Iterable, once you've finished adding all the items, you can loop over the contents using the enhanced for syntax:

Queue<String> globalQueue = new ConcurrentLinkedQueue<String>();

//Multiple threads can safely call globalQueue.add()...

for (String href : globalQueue) {
    //do something with href
}

Best thing I found is: https://github.com/mattt/TTTAttributedLabel

It's a UILabel subclass so you can just drop it in, and then to change the line height:

myLabel.lineHeightMultiple = 0.85;
myLabel.leading = 2;

More universal can be: for each v Selection : v.value = "'" & v.value : next and selecting range of cells before execution

this works for me:

cmake -D DBUILD_SHARED_LIBS=ON DBUILD_STATIC_LIBS=ON DBUILD_TESTS=ON ..

Sometimes you just need to recreate new device

In your entity class, when you declare mapping from user to roles, try specifying the fetchType to EAGER. Some thing like this:

@OneToMany(fetch=FetchType.EAGER)
public Collection<Role> getRoleSet(){
 ...
}

UPDATE: Recent comments this answer's received make me revisit this. It's been a while since I answered, when I only started working with Hibernate. What Rafael and Mukus say are reasonable. If you have a large collection, you shouldn't use eager fetching. It jointly selects all data mapped to your entry and loads to memory. An alternative to this is to still use lazy fetching and open a Hibernate session each time you need to work on the related collection, i.e, each time you need to invoke getRoleSet method. This way, Hibernate will execute the select query to database each time this method is invoked and doesn't keep the collection data in memory. You can refer to my post here for details: http://khuevu.github.io/2013/01/20/understand-hibernate.html

That's said, it can depend on your actual use case. If your collection data is small and you frequently need to query the data, you will better off using eager fetching. I think, in your specific case, a collection of role is probably quite small and suitable to use eager fetching.

When you are using Express edition you can try this:

#if DEBUG
    if( fooVariable == true )
        System.Diagnostics.Debugger.Break();
#endif

if statement makes sure that in release build breakepoint will not be present.

Use this one line query, replace desired_column_name by your column name.

SELECT TABLE_NAME FROM information_schema.columns WHERE column_name = 'desired_column_name';

@RichieHindle solution is now deprecated as of Visual Studio 2012. As the VS studio prompt now states:

Screenshot:

If you plan to use the signed distance calculation snippet posted by phi (like I did) and your b might have value 0, you probably want to fix the code as described below:

import math

def distance(a, b):
    if (a == b):
        return 0
    elif (a < 0) and (b < 0) or (a > 0) and (b >= 0): # fix: b >= 0 to cover case b == 0
        if (a < b):
            return (abs(abs(a) - abs(b)))
        else:
            return -(abs(abs(a) - abs(b)))
    else:
        return math.copysign((abs(a) + abs(b)),b)

The original snippet does not work correctly regarding sign when a > 0 and b == 0.

I had a similar problem in IntelliJ IDEA. My code was 100% correct, but after starting the Tomcat, you receive an exception. java.lang.IllegalStateException: Neither BindingResult

I just removed and added again Tomcat configuration. And it worked for me.

A picture Tomcat configuration

I got so fed up with checking for null and empty strings specifically, that I now usually just write and call a small function to do it for me.

/**
 * Test if the given value equals null or the empty string.
 * 
 * @param {string} value
**/
const isEmpty = (value) => value === null || value === '';

// Test:
isEmpty('');        // true
isEmpty(null);      // true
isEmpty(1);         // false
isEmpty(0);         // false
isEmpty(undefined); // false

lambda should be useful for this case. For example,

1. create function y=x+1 y=lambda x:x+1

2. call the function y(1) then return 2.

This works in Chrome 26, Internet Explorer 9 and Safari 5.1.7 (without the use of a helper page, ala Nick's answer):

<script type="text/javascript">
    window.open('javascript:window.open("", "_self", "");window.close();', '_self');
</script>

The nested window.open is to make IE not display the Do you want to close this window prompt.

Unfortunately it is impossible to get Firefox to close the window.

The image below helps show the differences between B+ trees and B trees.

Advantages of B+ trees:

• Because B+ trees don't have data associated with interior nodes, more keys can fit on a page of memory. Therefore, it will require fewer cache misses in order to access data that is on a leaf node.
• The leaf nodes of B+ trees are linked, so doing a full scan of all objects in a tree requires just one linear pass through all the leaf nodes. A B tree, on the other hand, would require a traversal of every level in the tree. This full-tree traversal will likely involve more cache misses than the linear traversal of B+ leaves.

Advantage of B trees:

• Because B trees contain data with each key, frequently accessed nodes can lie closer to the root, and therefore can be accessed more quickly.

One more efficient implementation

int i, j;

/* new length of modified array */
int NewLength = 1;

for(i=1; i< Length; i++){

   for(j=0; j< NewLength ; j++)
   {

      if(array[i] == array[j])
      break;
   }

   /* if none of the values in index[0..j] of array is not same as array[i],
      then copy the current value to corresponding new position in array */

  if (j==NewLength )
      array[NewLength++] = array[i];
}

In this implementation there is no need for sorting the array. Also if a duplicate element is found, there is no need for shifting all elements after this by one position.

The output of this code is array[] with size NewLength

Here we are starting from the 2nd elemt in array and comparing it with all the elements in array up to this array. We are holding an extra index variable 'NewLength' for modifying the input array. NewLength variabel is initialized to 0.

Element in array[1] will be compared with array[0]. If they are different, then value in array[NewLength] will be modified with array[1] and increment NewLength. If they are same, NewLength will not be modified.

So if we have an array [1 2 1 3 1], then

In First pass of 'j' loop, array[1] (2) will be compared with array0, then 2 will be written to array[NewLength] = array[1] so array will be [1 2] since NewLength = 2

In second pass of 'j' loop, array[2] (1) will be compared with array0 and array1. Here since array[2] (1) and array0 are same loop will break here. so array will be [1 2] since NewLength = 2

and so on

Also consider Int16. If you need to store an Integer in memory in your application and you are concerned about the amount of memory used, then you could go with Int16 since it uses less memeory and has a smaller min/max range than Int32 (which is what int is.)

typeid(uint8_t).name() is nice, but it returns "unsigned char" while you may expect "uint8_t".

This piece of code will return you the appropriate type

#define DECLARE_SET_FORMAT_FOR(type) \
    if ( typeid(type) == typeid(T) ) \
        formatStr = #type;

template<typename T>
static std::string GetFormatName()
{
    std::string formatStr;

    DECLARE_SET_FORMAT_FOR( uint8_t ) 
    DECLARE_SET_FORMAT_FOR( int8_t ) 

    DECLARE_SET_FORMAT_FOR( uint16_t )
    DECLARE_SET_FORMAT_FOR( int16_t )

    DECLARE_SET_FORMAT_FOR( uint32_t )
    DECLARE_SET_FORMAT_FOR( int32_t )

    DECLARE_SET_FORMAT_FOR( float )

    // .. to be exptended with other standard types you want to be displayed smartly

    if ( formatStr.empty() )
    {
        assert( false );
        formatStr = typeid(T).name();
    }

    return formatStr;
}

__FUNCTION__ is non standard, __func__ exists in C99 / C++11. The others (__LINE__ and __FILE__) are just fine.

It will always report the right file and line (and function if you choose to use __FUNCTION__/__func__). Optimization is a non-factor since it is a compile time macro expansion; it will never affect performance in any way.

The only things I can think of are

1. including files
2. replacing elements within files using preg_match_all
3. using assigned variables

I have recently been using str_replace and setting text in the HTML portion like so

{{TEXT_TO_REPLACE}}

using file_get_contents() you can grab html data and then organise it how you like.

here is a demo

myReplacementCodeFunction(){
  $text = '<img src="'.$row['name'].'" />'; 
  $text .= "<div>".$row['name']."</div>";
  $text .= "<div>".$row['title']."</div>";
  $text .= "<div>".$row['description']."</div>";
  $text .= "<div>".$row['link']."</div>";
  $text .= "<br />";
  return $text;
}

$htmlContents = file_get_contents("myhtmlfile.html");
$htmlContents = str_replace("{{TEXT_TO_REPLACE}}", myReplacementCodeFunction(), $htmlContents);
echo $htmlContents;

and now a demo html file:

<html>
<head>
   <style type="text/css">
      body{background:#666666;}
      div{border:1px solid red;}
   </style>
  </head>
  <body>
    {{TEXT_TO_REPLACE}}
  </body>
</html>

In my case, @ caused some sort of encoding problem, I still prefer my old way:

curl -d "$(cat /path/to/file)" https://example.com

At first, the problem is because you did't put any parameter for mysqli_error. I can see that it has been solved based on the post here. Most probably, the next problem is cause by wrong file path for the included file.. .

Are you sure this code

$myConnection = mysqli_connect("$db_host","$db_username","$db_pass","$db_name") or die ("could not connect to mysql");

is in the 'scripts' folder and your main code file is on the same level as the script folder?

Doesn't independent means that Java code should be able to run on any machine and would need no special software to be installed (JVM in this case has to be present in the machine)?

With Java, you can compile source code on Windows and the compiled code (bytecode to be precise) can be executed (interpreted) on any platform running a JVM. So yes you need a JVM but the JVM can run any compiled code, the compiled code is platform independent.

In other words, you have both portability of source code and portability of compiled code.

Like, for example, we need to have Turbo C Compiler in order to compile C/C++ source code and then execute it.. The machine has to have the C compiler.

The machine doesn't have to have a C compiler, the machine has to use a platform specific binary. With C or C++, the compiled code is specific to each architecture, it is platform independent.

In other words, with C / C++ you have portability of source code (with some discipline) but not portability of compiled code: you need to recompile for each architecture into platform specific binaries.

cURL is disabled for most hosting control panels for security reasons, but it's required for a lot of php applications. It's not unusual for a client to request it. Since the risk of enabling cURL is minimal, you are probably better off enabling it than losing a customer. It's simply a utility that helps php scripts fetch things using standard Internet URLs.

To enable cURL, you will remove curl_exec from the "disabled list" in the control panel php advanced settings. You will also find a disabled list in the various php.ini files; look in /etc/php.ini and other paths that might exist for your control panel. You will need to restart Apache to make the change take effect.

service httpd restart

To confirm whether cURL is enabled or disabled, create a file somewhere in your system and paste the following contents.

<?php
echo '<pre>';
var_dump(curl_version());
echo '</pre>';
?>

Save the file as testcurl.php and then run it as a php script.

php testcurl.php

If cURL is disabled you will see this error.

Fatal error: Call to undefined function curl_version() in testcurl.php on line 2

If cURL is enabled you will see a long list of attributes, like this.

Why I can't initialize static data members in class?

The C++ standard allows only static constant integral or enumeration types to be initialized inside the class. This is the reason a is allowed to be initialized while others are not.

Reference:
C++03 9.4.2 Static data members
§4

If a static data member is of const integral or const enumeration type, its declaration in the class definition can specify a constant-initializer which shall be an integral constant expression (5.19). In that case, the member can appear in integral constant expressions. The member shall still be defined in a namespace scope if it is used in the program and the namespace scope definition shall not contain an initializer.

What are integral types?

C++03 3.9.1 Fundamental types
§7

Types bool, char, wchar_t, and the signed and unsigned integer types are collectively called integral types.43) A synonym for integral type is integer type.

Footnote:

⁴³⁾ Therefore, enumerations (7.2) are not integral; however, enumerations can be promoted to int, unsigned int, long, or unsigned long, as specified in 4.5.

Workaround:

You could use the enum trick to initialize an array inside your class definition.

class A 
{
    static const int a = 3;
    enum { arrsize = 2 };

    static const int c[arrsize] = { 1, 2 };

};

Why does the Standard does not allow this?

Bjarne explains this aptly here:

A class is typically declared in a header file and a header file is typically included into many translation units. However, to avoid complicated linker rules, C++ requires that every object has a unique definition. That rule would be broken if C++ allowed in-class definition of entities that needed to be stored in memory as objects.

Why are only static const integral types & enums allowed In-class Initialization?

The answer is hidden in Bjarne's quote read it closely,
"C++ requires that every object has a unique definition. That rule would be broken if C++ allowed in-class definition of entities that needed to be stored in memory as objects."

Note that only static const integers can be treated as compile time constants. The compiler knows that the integer value will not change anytime and hence it can apply its own magic and apply optimizations, the compiler simply inlines such class members i.e, they are not stored in memory anymore, As the need of being stored in memory is removed, it gives such variables the exception to rule mentioned by Bjarne.

It is noteworthy to note here that even if static const integral values can have In-Class Initialization, taking address of such variables is not allowed. One can take the address of a static member if (and only if) it has an out-of-class definition.This further validates the reasoning above.

enums are allowed this because values of an enumerated type can be used where ints are expected.^{see citation above}

How does this change in C++11?

C++11 relaxes the restriction to certain extent.

C++11 9.4.2 Static data members
§3

If a static data member is of const literal type, its declaration in the class definition can specify a brace-or-equal-initializer in which every initializer-clause that is an assignment-expression is a constant expression. A static data member of literal type can be declared in the class definition with the constexpr specifier; if so, its declaration shall specify a brace-or-equal-initializer in which every initializer-clause that is an assignment-expression is a constant expression. [ Note: In both these cases, the member may appear in constant expressions. —end note ] The member shall still be defined in a namespace scope if it is used in the program and the namespace scope definition shall not contain an initializer.

Also, C++11 will allow(§12.6.2.8) a non-static data member to be initialized where it is declared(in its class). This will mean much easy user semantics.

Note that these features have not yet been implemented in latest gcc 4.7, So you might still get compilation errors.

Adobe Illustrator uses bezier curves like SVG, and for circles it creates four points. You can create a circle with two elliptical arc commands...but then for a circle in SVG I would use a <circle /> :)

You also can use in this form:

<a href="@Url.Action("Information", "Admin", null)"> Admin</a>

Old post, but I'd say the cleanest approach would be to add a class to the surrounding div and a button class on each button so your CSS rule becomes useful for more use cases:

/* Added to highlight spacing */_x000D_
.is-grouped {   _x000D_
    display: inline-block;_x000D_
    background-color: yellow;_x000D_
}_x000D_
_x000D_
.is-grouped > .button:not(:last-child) {_x000D_
    margin-right: 10px;_x000D_
}

Spacing shown in yellow<br><br>_x000D_
_x000D_
<div class='is-grouped'>_x000D_
    <button class='button'>Save</button>_x000D_
    <button class='button'>Save As...</button>_x000D_
    <button class='button'>Delete</button>_x000D_
</div>

You must use %ld to print a long int, and %lld to print a long long int.

Note that only long long int is guaranteed to be large enough to store the result of that calculation (or, indeed, the input values you're using).

You will also need to ensure that you use your compiler in a C99-compatible mode (for example, using the -std=gnu99 option to gcc). This is because the long long int type was not introduced until C99; and although many compilers implement long long int in C90 mode as an extension, the constant 2147483648 may have a type of unsigned int or unsigned long in C90. If this is the case in your implementation, then the value of -2147483648 will also have unsigned type and will therefore be positive, and the overall result will be not what you expect.

Per the comments to the original post, merges / joins are well-suited for this problem. In particular, an inner join will return only values that are present in both dataframes, making thesetdiff statement unnecessary.

Using the data from Dinre's example:

In base R:

cleanedA <- merge(data_A, data_B[, "index"], by = 1, sort = FALSE)
cleanedB <- merge(data_B, data_A[, "index"], by = 1, sort = FALSE)

Using the dplyr package:

library(dplyr)
cleanedA <- inner_join(data_A, data_B %>% select(index))
cleanedB <- inner_join(data_B, data_A %>% select(index))

To keep the data as two separate tables, each containing only its own variables, this subsets the unwanted table to only its index variable before joining. Then no new variables are added to the resulting table.

There are many cases when small differences between environments can bite you. This is one into which I have ran recently. What is the difference between these two commands?

1 ~ $ nohup myprocess.out &
2 ~ $ myprocess.out &

The answer is the same as usual - it depends.

nohup catches the hangup signal while the ampersand does not.

What is the hangup signal?

SIGHUP - hangup detected on controlling terminal or death of controlling process (value: 1).

Normally, when running a command using & and exiting the shell afterwards, the shell will terminate the sub-command with the hangup signal (like kill -SIGHUP $PID). This can be prevented using nohup, as it catches the signal and ignores it so that it never reaches the actual application.

Fine, but like in this case there are always ‘buts’. There is no difference between these launching methods when the shell is configured in a way where it does not send SIGHUP at all.

In case you are using bash, you can use the command specified below to find out whether your shell sends SIGHUP to its child processes or not:

~ $ shopt | grep hupon

And moreover - there are cases where nohup does not work. For example, when the process you start reconnects the NOHUP signal (it is done inside, on the application code level).

In the described case, lack of differences bit me when inside a custom service launching script there was a call to a second script which sets up and launches the proper application without a nohup command.

On one Linux environment everything worked smoothly, on a second one the application quit as soon as the second script exited (detecting that case, of course took me much more time then you might think :stuck_out_tongue:).

After adding nohup as a launching method to second script, application keeps running even if the scripts will exit and this behavior became consistent on both environments.

If you want to specifically use java ArrayList then you can do something like this:

fun initList(){
    val list: ArrayList<String> = ArrayList()
    list.add("text")
    println(list)
}

Otherwise @guenhter answer is the one you are looking for.

If you know that certain characters are not used, you can translate "\t" into something else. cat my_file | tr "\t" "," | sed "s/(.*)/,\1/"

v%

will select the whole block.

Play with also:

v}, vp, vs, etc.

See help:

:help text-objects

which lists the different ways to select letters, words, sentences, paragraphs, blocks, and so on.

$ends_with = strrchr($text, '.'); // Ends with dot
$start_with = (0 === strpos($text, '.')); // Starts with dot

Funny you brought this up, I just had the exact same problem. I solved it eventually, but I'm still unsure as to what caused it.

Try checking your bin/pip and bin/activate scripts. In bin/pip, look at the shebang. Is it correct? If not, correct it. Then on line ~42 in your bin/activate, check to see if your virtualenv path is right. It'll look something like this

VIRTUAL_ENV="/Users/me/path/to/virtual/environment"

If it's wrong, correct it, deactivate, then . bin/activate, and if our mutual problem had the same cause, it should work. If it still doesn't, you're on the right track, anyway. I went through the same problem solving routine as you did, which piping over and over, following the stack trace, etc.

Make absolutely sure that

/Users/kristof/VirtualEnvs/testpy3/bin/pip3

is what you want, and not referring to another similarly-named test project (I had that problem, and have no idea how it started. My suspicion is running multiple virtualenvs at the same time).

If none of this works, a temporary solution may be to, as Joe Holloway said,

Just run the virtualenv's pip with its full path (i.e. don't rely on searching the executable path) and you don't even need to activate the environment. It will do the right thing.

Perhaps not ideal, but it ought to work in a pinch.

Link to my original question:

VirtualEnv/Pip trying to install packages globally

<?php
ini_set("SMTP", "aspmx.l.google.com");
ini_set("sendmail_from", "[email protected]");

$message = "The mail message was sent with the following mail setting:\r\nSMTP = aspmx.l.google.com\r\nsmtp_port = 25\r\nsendmail_from = [email protected]";

$headers = "From: [email protected]";

mail("[email protected]", "Testing", $message, $headers);
echo "Check your email now....&lt;BR/>";
?>

or, for more details, read on.

As far as I know, the order of the repositories in your pom.xml will also decide the order of the repository access.

As for configuring repositories in settings.xml, I've read that the order of repositories is interestingly enough the inverse order of how the repositories will be accessed.

Here a post where someone explains this curiosity:
http://community.jboss.org/message/576851

Just in case you arrived here because you copied a branch name from Github, note that a remote branch is not automatically also a local branch, so a merge will not work and give the "not something we can merge" error.

In that case, you have two options:

git checkout [branchYouWantToMergeInto]
git merge origin/[branchYouWantToMerge]

or

# this creates a local branch
git checkout [branchYouWantToMerge]

git checkout [branchYouWantToMergeInto]
git merge [branchYouWantToMerge]

just simply press enter it make a break

I think you can do something like this..

EDIT : Changed the code to work irrespective of the caret postion

First part of the code is to get the caret position.

Ref: How to get the caret column (not pixels) position in a textarea, in characters, from the start?

function getCaret(el) { 
    if (el.selectionStart) { 
        return el.selectionStart; 
    } else if (document.selection) { 
        el.focus();
        var r = document.selection.createRange(); 
        if (r == null) { 
            return 0;
        }
        var re = el.createTextRange(), rc = re.duplicate();
        re.moveToBookmark(r.getBookmark());
        rc.setEndPoint('EndToStart', re);
        return rc.text.length;
    }  
    return 0; 
}

And then replacing the textarea value accordingly when Shift + Enter together , submit the form if Enter is pressed alone.

$('textarea').keyup(function (event) {
    if (event.keyCode == 13) {
        var content = this.value;  
        var caret = getCaret(this);          
        if(event.shiftKey){
            this.value = content.substring(0, caret - 1) + "\n" + content.substring(caret, content.length);
            event.stopPropagation();
        } else {
            this.value = content.substring(0, caret - 1) + content.substring(caret, content.length);
            $('form').submit();
        }
    }
});

Here is a demo

can use

border-width:2px;
border-style:solid;
border-color:black;

or as shorthand

border: 2px solid black

A while loop can be simulated in cmd.exe with:

:still_more_files
    if %countfiles% leq 21 (
        rem change countfile here
        goto :still_more_files
    )

For example, the following script:

    @echo off
    setlocal enableextensions enabledelayedexpansion
    set /a "x = 0"

:more_to_process
    if %x% leq 5 (
        echo %x%
        set /a "x = x + 1"
        goto :more_to_process
    )

    endlocal

outputs:

0
1
2
3
4
5

For your particular case, I would start with the following. Your initial description was a little confusing. I'm assuming you want to delete files in that directory until there's 20 or less:

    @echo off
    set backupdir=c:\test

:more_files_to_process
    for /f %%x in ('dir %backupdir% /b ^| find /v /c "::"') do set num=%%x
    if %num% gtr 20 (
        cscript /nologo c:\deletefile.vbs %backupdir%
        goto :more_files_to_process
    )

if(navigator.app){
        navigator.app.exitApp();
}else if(navigator.device){
        navigator.device.exitApp();
}

Keith Elder nicely compares ASMX to WCF here. Check it out.

Another comparison of ASMX and WCF can be found here - I don't 100% agree with all the points there, but it might give you an idea.

WCF is basically "ASMX on stereoids" - it can be all that ASMX could - plus a lot more!.

ASMX is:

• easy and simple to write and configure
• only available in IIS
• only callable from HTTP

WCF can be:

• hosted in IIS, a Windows Service, a Winforms application, a console app - you have total freedom
• used with HTTP (REST and SOAP), TCP/IP, MSMQ and many more protocols

In short: WCF is here to replace ASMX fully.

Check out the WCF Developer Center on MSDN.

Check if you're referencing jquery.js BEFORE bootstrap.js and bootstrap.js is loaded only once. That fixed the same error for me:

You could read the html file manually and then use loadData or loadDataWithBaseUrl methods of WebView to show it.

I met the same question, and solved it by using SSH protocol.

git clone [email protected]:micro/micro.git

It breaks pages using XML rendering (like XHTML pages).

Best: some browser switch back to HTML rendering and everything works fine.

Probable: some browser disable the document.write() function in XML rendering mode.

Worst: some browser will fire an XML error whenever using the document.write() function.

Thought about using the test to pass in the vars? Something like:

Test input would be something like:

{
  "TABLE_NAME": "MyDevTable",
  "PARTITION_KEY": "REGION",
  "SORT_KEY": "COUNTRY"
}

Adjusted your code to accept the inputs:

const AWS = require('aws-sdk');
const docClient = new AWS.DynamoDB.DocumentClient({ apiVersion: '2012-08-10' });

exports.handler = async (event) => {
    const TABLE_NAME = event.TABLE_NAME;
    const PARTITION_KEY = event.PARTITION_KEY;
    const SORT_KEY = event.SORT_KEY;
    let params = {
        TableName: TABLE_NAME,
    };
    console.log(`keys: ${PARTITION_KEY} ${SORT_KEY}`);

    let items = [];
    let data = await docClient.scan(params).promise();
    items = [...items, ...data.Items];
    
    while (typeof data.LastEvaluatedKey != 'undefined') {
        params.ExclusiveStartKey = data.LastEvaluatedKey;

        data = await docClient.scan(params).promise();
        items = [...items, ...data.Items];
    }

    let leftItems = items.length;
    let group = [];
    let groupNumber = 0;

    console.log('Total items to be deleted', leftItems);

    for (const i of items) {
        // console.log(`item: ${i[PARTITION_KEY] } ${i[SORT_KEY]}`);
        const deleteReq = {DeleteRequest: {Key: {},},};
        deleteReq.DeleteRequest.Key[PARTITION_KEY] = i[PARTITION_KEY];
        deleteReq.DeleteRequest.Key[SORT_KEY] = i[SORT_KEY];

        // console.log(`DeleteRequest: ${JSON.stringify(deleteReq)}`);
        group.push(deleteReq);
        leftItems--;

        if (group.length === 25 || leftItems < 1) {
            groupNumber++;

            console.log(`Batch ${groupNumber} to be deleted.`);

            const params = {
                RequestItems: {
                    [TABLE_NAME]: group,
                },
            };

            await docClient.batchWrite(params).promise();

            console.log(
                `Batch ${groupNumber} processed. Left items: ${leftItems}`
            );

            // reset
            group = [];
        }
    }

    const response = {
        statusCode: 200,
        //  Uncomment below to enable CORS requests
        headers: {
            "Access-Control-Allow-Origin": "*"
        },
        body: JSON.stringify('Hello from Lambda!'),
    };
    return response;
};

@John Woo's answer helped me solve a similar problem. I've improved upon his answer by setting the correct ordering as well. This has worked for me:

SELECT  a.*, c.*
FROM users a 
    INNER JOIN payments c
        ON a.id = c.user_ID
    INNER JOIN (
        SELECT user_ID, MAX(date) as maxDate FROM
        (
            SELECT user_ID, date
            FROM payments
            ORDER BY date DESC
        ) d
        GROUP BY user_ID
    ) b ON c.user_ID = b.user_ID AND
           c.date = b.maxDate
WHERE a.package = 1

I'm not sure how efficient this is, though.

How about either of:

>>> df
         date  duration user_id
0  2013-04-01        30    0001
1  2013-04-01        15    0001
2  2013-04-01        20    0002
3  2013-04-02        15    0002
4  2013-04-02        30    0002
>>> df.groupby("date").agg({"duration": np.sum, "user_id": pd.Series.nunique})
            duration  user_id
date                         
2013-04-01        65        2
2013-04-02        45        1
>>> df.groupby("date").agg({"duration": np.sum, "user_id": lambda x: x.nunique()})
            duration  user_id
date                         
2013-04-01        65        2
2013-04-02        45        1

Try to replace the \n with %0A just like you have spaces replaced with %20.

You could approach this method.

Here is my solution. By calling the function below you ensure that all dirs leading to the file path specified exist. Note that file_path argument is not directory name here but rather a path to a file that you are going to create after calling mkpath().

Eg., mkpath("/home/me/dir/subdir/file.dat", 0755) shall create /home/me/dir/subdir if it does not exist. mkpath("/home/me/dir/subdir/", 0755) does the same.

Works with relative paths as well.

Returns -1 and sets errno in case of an error.

int mkpath(char* file_path, mode_t mode) {
    assert(file_path && *file_path);
    for (char* p = strchr(file_path + 1, '/'); p; p = strchr(p + 1, '/')) {
        *p = '\0';
        if (mkdir(file_path, mode) == -1) {
            if (errno != EEXIST) {
                *p = '/';
                return -1;
            }
        }
        *p = '/';
    }
    return 0;
}

Note that file_path is modified during the action but gets restored afterwards. Therefore file_path is not strictly const.

I would go for:

"([^"]*)"

The [^"] is regex for any character except '"'
The reason I use this over the non greedy many operator is that I have to keep looking that up just to make sure I get it correct.

For some programs setting the super secret __COMPAT_LAYER environment variable to RunAsInvoker will work.Check this :

set "__COMPAT_LAYER=RunAsInvoker"
start regedit.exe

Though like this there will be no UAC prompting the user will continue without admin permissions.

On a side note, it would have been much easier to just do this.

For debug purposes only, you can call _viewDelegate on views to get their view controllers. This is private API, so not safe for App Store, but for debugging it is useful.

Other useful methods:

• _viewControllerForAncestor - get the first controller that manages a view in the superview chain. (thanks n00neimp0rtant)
• _rootAncestorViewController - get the ancestor controller whose view hierarchy is set in the window currently.

Not the react way, but I beleive that this one-line function can help you :)

const getQueryParams = () => window.location.search.replace('?', '').split('&').reduce((r,e) => (r[e.split('=')[0]] = decodeURIComponent(e.split('=')[1]), r), {});

Example:
URL:  ...?a=1&b=c&d=test
Code:  

>  getQueryParams()
<  {
     a: "1",
     b: "c",
     d: "test"
   }

Returning the whole object on an update would not seem very relevant, but I can hardly see why returning the whole object when it is created would be a bad practice in a normal use case. This would be useful at least to get the ID easily and to get the timestamps when relevant. This is actually the default behavior got when scaffolding with Rails.

I really do not see any advantage to returning only the ID and doing a GET request after, to get the data you could have got with your initial POST.

Anyway as long as your API is consistent I think that you should choose the pattern that fits your needs the best. There is not any correct way of how to build a REST API, imo.

Above tools extract the jar. Also there are certain other tools and commands to extract the jar. But AFAIK you cant get the java code in case code has been obfuscated.

Theres the ByteArrayInputStream.

It does exactly this.

I had a similar problem but I found a 100% working solution for it.

<?php
    function super_unique($array,$key)
    {
       $temp_array = [];
       foreach ($array as &$v) {
           if (!isset($temp_array[$v[$key]]))
           $temp_array[$v[$key]] =& $v;
       }
       $array = array_values($temp_array);
       return $array;

    }


$arr="";
$arr[0]['id']=0;
$arr[0]['titel']="ABC";
$arr[1]['id']=1;
$arr[1]['titel']="DEF";
$arr[2]['id']=2;
$arr[2]['titel']="ABC";
$arr[3]['id']=3;
$arr[3]['titel']="XYZ";

echo "<pre>";
print_r($arr);
echo "unique*********************<br/>";
print_r(super_unique($arr,'titel'));

?>

Unfortunately, the Preferences dialog is not always very helpful, but by tweaking around you should be able to get everything working.

To be able to type Swedish characters in Terminal, add the following lines to your ~/.inputrc (most likely you must create this file):

set input-meta on
set output-meta on
set convert-meta off

This should do the work both with utf8 and other codings in bash, nano and many other programs. Some programs, like tmux, also depends on the locale. Then, adding for instance export LC_ALL=en_US.UTF-8 to your ~/.profile file should help, but keep in mind that a few (mainly obscure) programs require a standard locale, so if you have trouble running or compiling a program, try going back to LC_ALL=C.

Some references that may be helpful:

Here is a filter that use:

app.filter('milliSecondsToTimeCode', function () {
    return function msToTime(duration) {
        var milliseconds = parseInt((duration % 1000) / 100)
            , seconds = parseInt((duration / 1000) % 60)
            , minutes = parseInt((duration / (1000 * 60)) % 60)
            , hours = parseInt((duration / (1000 * 60 * 60)) % 24);

        hours = (hours < 10) ? "0" + hours : hours;
        minutes = (minutes < 10) ? "0" + minutes : minutes;
        seconds = (seconds < 10) ? "0" + seconds : seconds;

        return hours + ":" + minutes + ":" + seconds + "." + milliseconds;
    };
});

Just add it to your expression as such

{{milliseconds | milliSecondsToTimeCode}}

Two simple examples to capture output the pwd command:

$ b=$(pwd)
$ echo $b
/home/user1

or

$ a=`pwd`
$ echo $a
/home/user1

The first way is preferred. Note that there can't be any spaces after the = for this to work.

Example using a short script:

#!/bin/bash

echo "hi there"

then:

$ ./so.sh
hi there
$ a=$(so.sh)
$ echo $a
hi there

In general a more flexible approach would be to return an exit value from the command and use it for further processing, though sometimes we just may want to capture the simple output from a command.

I've written just this to execute compiling and run the file after, plus fileinputname = fileoutputname on windowsmashines, if your compilerpath is registred in the windows PATH-var:

NPP_SAVE
cd "$(CURRENT_DIRECTORY)"
set LEN~ strrfind $(FILE_NAME) .
set EXENAME ~ substr 0 $(LEN) $(FILE_NAME)
set $(EXENAME) = $(EXENAME).exe
c++.exe "$(FILE_NAME)" -o "$(EXENAME)"
"$(EXENAME)"

should work for any compiler if you change c++.exe to what you want

I really like the Broken Arrow's solution above in this post. I have just improved/changed it a bit so that what was called labels can be toggled and are not considered options. I have used a small piece of jQuery, but this could be done without jQuery.

I have replaced intermediate labels (no leaf labels) with links, which call a function on click. This function is in charge of toggling the next div of the clicked link, so that it expands/collapses the options. This avoids the possibility of selecting an intermediate element in the hierarchy, which usually is something desired. Making a variant that allows to select intermediate elements should be easy.

This is the modified html:

<div class="NestedSelect">
    <a onclick="toggleDiv(this)">Fruit</a>
    <div>
        <label>
            <input type="radio" name="MySelectInputName"><span>Apple</span></label>
        <label>
            <input type="radio" name="MySelectInputName"><span>Banana</span></label>
        <label>
            <input type="radio" name="MySelectInputName"><span>Orange</span></label>
    </div>

    <a onclick="toggleDiv(this)">Drink</a>
    <div>
        <label>
            <input type="radio" name="MySelectInputName"><span>Water</span></label>

        <a onclick="toggleDiv(this)">Soft</a>
        <div>
            <label>
                <input type="radio" name="MySelectInputName"><span>Cola</span></label>
            <label>
                <input type="radio" name="MySelectInputName"><span>Soda</span></label>
            <label>
                <input type="radio" name="MySelectInputName"><span>Lemonade</span></label>
        </div>

        <a onclick="toggleDiv(this)">Hard</a>
        <div>
            <label>
                <input type="radio" name="MySelectInputName"><span>Bear</span></label>
            <label>
                <input type="radio" name="MySelectInputName"><span>Whisky</span></label>
            <label>
                <input type="radio" name="MySelectInputName"><span>Vodka</span></label>
            <label>
                <input type="radio" name="MySelectInputName"><span>Gin</span></label>
        </div>
    </div>
</div>

A small javascript/jQuery function:

function toggleDiv(element) {
    $(element).next('div').toggle('medium');
}

And the css:

.NestedSelect {
    display: inline-block;
    height: 100%;
    border: 1px Black solid;
    overflow-y: scroll;
}

.NestedSelect a:hover, .NestedSelect span:hover  {
    background-color: #0092ff;
    color: White;
    cursor: pointer;
}

.NestedSelect input[type="radio"] {
    display: none;
}

.NestedSelect input[type="radio"] + span {
    display: block;
    padding-left: 0px;
    padding-right: 5px;
}

.NestedSelect input[type="radio"]:checked + span {
    background-color: Black;
    color: White;
}

.NestedSelect div {
    display: none;
    margin-left: 15px;
    border-left: 1px black
    solid;
}

.NestedSelect label > span:before, .NestedSelect a:before{
    content: '- ';
}

.NestedSelect a {
    display: block;
}

Running sample in JSFiddle

If you want to see the array as an array, you can say

alert(JSON.stringify(aCustomers));

instead of all those document.writes.

http://jsfiddle.net/5b2eb/

However, if you want to display them cleanly, one per line, in your popup, do this:

alert(aCustomers.join("\n"));

http://jsfiddle.net/5b2eb/1/

You have to set Connection property of Command object and use parametersized query instead of hardcoded SQL to avoid SQL Injection.

 using(SqlConnection openCon=new SqlConnection("your_connection_String"))
    {
      string saveStaff = "INSERT into tbl_staff (staffName,userID,idDepartment) VALUES (@staffName,@userID,@idDepartment)";

      using(SqlCommand querySaveStaff = new SqlCommand(saveStaff))
       {
         querySaveStaff.Connection=openCon;
         querySaveStaff.Parameters.Add("@staffName",SqlDbType.VarChar,30).Value=name;
         .....
         openCon.Open();

         querySaveStaff.ExecuteNonQuery();
       }
     }

If you want to remove EVERYTHING :

textarea {
    border: none;
    background-color: transparent;
    resize: none;
    outline: none;
}

No, you can't configure memory amount needed by VM. However, note that this is virtual memory, not resident, so it just stays there without harm if not actually used.

Alernatively, you can try some other JVM then Sun one, with smaller memory footprint, but I can't advise here.

If you have a String object you want to tokenize, favor using String's split method over a StringTokenizer. If you're parsing text data from a source outside your program, like from a file, or from the user, that's where a Scanner comes in handy.

This shall also work.

SSL properties are set at the JVM level via system properties. Meaning you can either set them when you run the program (java -D....) Or you can set them in code by doing System.setProperty.

The specific keys you have to set are below:

javax.net.ssl.keyStore- Location of the Java keystore file containing an application process's own certificate and private key. On Windows, the specified pathname must use forward slashes, /, in place of backslashes.

javax.net.ssl.keyStorePassword - Password to access the private key from the keystore file specified by javax.net.ssl.keyStore. This password is used twice: To unlock the keystore file (store password), and To decrypt the private key stored in the keystore (key password).

javax.net.ssl.trustStore - Location of the Java keystore file containing the collection of CA certificates trusted by this application process (trust store). On Windows, the specified pathname must use forward slashes, /, in place of backslashes, \.

If a trust store location is not specified using this property, the SunJSSE implementation searches for and uses a keystore file in the following locations (in order):

1. $JAVA_HOME/lib/security/jssecacerts
2. $JAVA_HOME/lib/security/cacerts

javax.net.ssl.trustStorePassword - Password to unlock the keystore file (store password) specified by javax.net.ssl.trustStore.

javax.net.ssl.trustStoreType - (Optional) For Java keystore file format, this property has the value jks (or JKS). You do not normally specify this property, because its default value is already jks.

javax.net.debug - To switch on logging for the SSL/TLS layer, set this property to ssl.

I needed to download and install the Windows 8.0 (and not 8.1) SDK to make the error disappear on my TeamCity server.

If you get a Error 509 in Libre office you may replace , by ; in the DATE() function

=(((COLUMN_ID_HERE/60)/60)/24)+DATE(1970;1;1)

Here is code that should replace document.write in-place:

document.write=function(s){
    var scripts = document.getElementsByTagName('script');
    var lastScript = scripts[scripts.length-1];
    lastScript.insertAdjacentHTML("beforebegin", s);
}

You can do just:

var regex = /^[1-9]\d{0,2}$/g
regex.test('2') // outputs true

From MSDN -

CollectionViewSource.GetDefaultView(myGrid.ItemsSource).Refresh();

Each key in a HashMap must be unique.

When "adding a duplicate key" the old value (for the same key, as keys must be unique) is simply replaced; see HashMap.put:

Associates the specified value with the specified key in this map. If the map previously contained a mapping for the key, the old value is replaced.

Returns the previous value associated with key, or null if there was no mapping for key.

As far as nulls: a single null key is allowed (as keys must be unique) but the HashMap can have any number of null values, and a null key need not have a null value. Per the documentation:

[.. HashMap] permits null values and [a] null key.

However, the documentation says nothing about null/null needing to be a specific key/value pair or null/"a" being invalid.

Try this.

 objectMapper.enable(SerializationConfig.Feature.INDENT_OUTPUT);

If updating cURL doesn't fix it, updating NSS should do the trick.

You can simply read each line from the file and assign it to an array.

#!/bin/bash
i=0
while read line 
do
        arr[$i]="$line"
        i=$((i+1))
done < file.txt

Try the Parse method.

You should type into the command line

git add --all

This will commit all untracked files

Edit:

After staging your files they are ready for commit so your next command should be

git commit -am "Your commit message"

Since others have covered the differences, I'll hit the uses.

TIFF is usually used by scanners. It makes huge files and is not really used in applications.

BMP is uncompressed and also makes huge files. It is also not really used in applications.

GIF used to be all over the web but has fallen out of favor since it only supports a limited number of colors and is patented.

JPG/JPEG is mainly used for anything that is photo quality, though not for text. The lossy compression used tends to mar sharp lines.

PNG isn't as small as JPEG but is lossless so it's good for images with sharp lines. It's in common use on the web now.

Personally, I usually use PNG everywhere I can. It's a good compromise between JPG and GIF.

You can do it directly on the style:

var nFilter = document.createElement('div');
nFilter.className = 'well';
nFilter.innerHTML = '<label>'+sSearchStr+'</label>';

// Css styling
nFilter.style.width = "330px";
nFilter.style.float = "left";

// or
nFilter.setAttribute("style", "width:330px;float:left;");

You should be able to do the count on the purch variable:

purch.Count();

e.g.

var purch = from purchase in myBlaContext.purchases
select purchase;

purch.Count();

I'll post my memo here, because I have to come back here again and again.

SCENARIO 1. Normal developer: You are developer who can't merge to master and have to play with feature branches only.

Case 1: master is a king. You want to refresh your feature branch (= rebase to master), because master contains new updates of dependencies and you want to overwrite your modest changes.

git checkout master
git pull

git checkout feature
git rebase -X ours master

Case 2: you are a king. You want to rebase your feature branch to master changes. But you did more than your colleagues had and want to use your own changes in a priority.

git checkout master
git pull

git checkout feature
git rebase -X theirs master

IMPORTANT: As you can see normal developers should prefer rebase and repeat it every morning like exercises/coffee.

SCENARIO 2. Merging-sensei: You are a team-lead and want to merge other branches and push a merged result directly to a master. master is a branch you will change.

Case 1: master is a king You want to merge third-party branch, but master is a priority. feature is a branch that your senior did.

git checkout feature
git pull

git checkout master
git merge -X ours feature

Case 2: new changes is a king When your senior developer released a cool feature and you want to overwrite the old s**t in the master branch.

git checkout feature
git pull

git checkout master
git merge -X theirs feature

REMEMBER: To remember in a midnight which one to choose: master is ours ALWAYS. And theirs is a feature that theirs have done.

I have tried adding ;DATABASE_TO_UPPER=false parameter, which it did work a single test, but what did the trick for me was ;CASE_INSENSITIVE_IDENTIFIERS=TRUE.

At the I had: jdbc:h2:mem:testdb;CASE_INSENSITIVE_IDENTIFIERS=TRUE

Moreover, the problem for me was when I upgraded to Spring Boot 2.4.1.

Check out the pack URI syntax. You want something like this:

<ResourceDictionary Source="pack://application:,,,/YourAssembly;component/Subfolder/YourResourceFile.xaml"/>

Actually, if you're using AngularJS, you don't need jQuery anymore. AngularJS itself has the binding and directive, which is a very good "replacement" for most things you can do with jQuery.

I usually develop mobile applications using AngularJS and Cordova. The ONLY thing from jQuery I needed is the Selector.

By googling, I see that there is a standalone jQuery selector module out there. It's Sizzle.

And I decided to make a tiny code snippet that help me quickly start a website using AngularJS with the power of jQuery Selector (using Sizzle).

I shared my code here: https://github.com/huytd/Sizzular

This won't directly solve your problem as you want to switch on your own user-defined types, but for the benefit of others who only want to switch on built-in types, you can use the TypeCode enumeration:

switch (Type.GetTypeCode(node.GetType()))
{
    case TypeCode.Decimal:
        // Handle Decimal
        break;

    case TypeCode.Int32:
        // Handle Int32
        break;
     ...
}

This one is correct:

ALTER TABLE `users`
    ADD COLUMN `count` SMALLINT(6) NOT NULL AFTER `lastname`,
    ADD COLUMN `log` VARCHAR(12) NOT NULL AFTER `count`,
    ADD COLUMN `status` INT(10) UNSIGNED NOT NULL AFTER `log`;

var list = new List<string>();
var queryable = list.AsQueryable();

How to insert table values from one server/database to another database?

1 Creating Linked Servers {if needs} (SQL server 2008 R2 - 2012) http://technet.microsoft.com/en-us/library/ff772782.aspx#SSMSProcedure

2 configure the linked server to use Credentials a) http://technet.microsoft.com/es-es/library/ms189811(v=sql.105).aspx

EXEC sp_addlinkedsrvlogin 'NAMEOFLINKEDSERVER', 'false', null, 'REMOTEUSERNAME', 'REMOTEUSERPASSWORD'

-- CHECK SERVERS

SELECT * FROM sys.servers

-- TEST LINKED SERVERS

EXEC sp_testlinkedserver N'NAMEOFLINKEDSERVER'

INSERT INTO NEW LOCAL TABLE

SELECT * INTO NEWTABLE
FROM [LINKEDSERVER\INSTANCE].remoteDATABASE.remoteSCHEMA.remoteTABLE

OR

INSERT AS NEW VALUES IN REMOTE TABLE

INSERT
INTO    [LINKEDSERVER\INSTANCE].remoteDATABASE.remoteSCHEMA.remoteTABLE
SELECT  *
FROM    localTABLE

INSERT AS NEW LOCAL TABLE VALUES

INSERT
INTO    localTABLE
SELECT  *
FROM    [LINKEDSERVER\INSTANCE].remoteDATABASE.remoteSCHEMA.remoteTABLE

I had this problem with this kind of simple form:

public partial class MyForm : Form
{
    public MyForm()
    {
        Load += new EventHandler(Form1_Load);
    }

    private void Form1_Load(Object sender, EventArgs e)
    {
        InitializeComponent();
    }

    internal void UpdateLabel(string s)
    {
        Invoke(new Action(() => { label1.Text = s; }));
    }
}

Then for n other async threads I was using new MyForm().UpdateLabel(text) to try and call the UI thread, but the constructor gives no handle to the UI thread instance, so other threads get other instance handles, which are either Object reference not set to an instance of an object or Invoke or BeginInvoke cannot be called on a control until the window handle has been created. To solve this I used a static object to hold the UI handle:

public partial class MyForm : Form
{
    private static MyForm _mf;        

    public MyForm()
    {
        Load += new EventHandler(Form1_Load);
    }

    private void Form1_Load(Object sender, EventArgs e)
    {
        InitializeComponent();
        _mf = this;
    }

    internal void UpdateLabel(string s)
    {
        _mf.Invoke((MethodInvoker) delegate { _mf.label1.Text = s; });
    }
}

I guess it's working fine, so far...

This is another valid way to make a copy of a vector, just use its constructor:

std::vector<int> newvector(oldvector);

This is even simpler than using std::copy to walk the entire vector from start to finish to std::back_insert them into the new vector.

That being said, your .swap() one is not a copy, instead it swaps the two vectors. You would modify the original to not contain anything anymore! Which is not a copy.

if any interested I've made a typescript version:

interface IResizeImageOptions {
  maxSize: number;
  file: File;
}
const resizeImage = (settings: IResizeImageOptions) => {
  const file = settings.file;
  const maxSize = settings.maxSize;
  const reader = new FileReader();
  const image = new Image();
  const canvas = document.createElement('canvas');
  const dataURItoBlob = (dataURI: string) => {
    const bytes = dataURI.split(',')[0].indexOf('base64') >= 0 ?
        atob(dataURI.split(',')[1]) :
        unescape(dataURI.split(',')[1]);
    const mime = dataURI.split(',')[0].split(':')[1].split(';')[0];
    const max = bytes.length;
    const ia = new Uint8Array(max);
    for (var i = 0; i < max; i++) ia[i] = bytes.charCodeAt(i);
    return new Blob([ia], {type:mime});
  };
  const resize = () => {
    let width = image.width;
    let height = image.height;

    if (width > height) {
        if (width > maxSize) {
            height *= maxSize / width;
            width = maxSize;
        }
    } else {
        if (height > maxSize) {
            width *= maxSize / height;
            height = maxSize;
        }
    }

    canvas.width = width;
    canvas.height = height;
    canvas.getContext('2d').drawImage(image, 0, 0, width, height);
    let dataUrl = canvas.toDataURL('image/jpeg');
    return dataURItoBlob(dataUrl);
  };

  return new Promise((ok, no) => {
      if (!file.type.match(/image.*/)) {
        no(new Error("Not an image"));
        return;
      }

      reader.onload = (readerEvent: any) => {
        image.onload = () => ok(resize());
        image.src = readerEvent.target.result;
      };
      reader.readAsDataURL(file);
  })    
};

and here's the javascript result:

var resizeImage = function (settings) {
    var file = settings.file;
    var maxSize = settings.maxSize;
    var reader = new FileReader();
    var image = new Image();
    var canvas = document.createElement('canvas');
    var dataURItoBlob = function (dataURI) {
        var bytes = dataURI.split(',')[0].indexOf('base64') >= 0 ?
            atob(dataURI.split(',')[1]) :
            unescape(dataURI.split(',')[1]);
        var mime = dataURI.split(',')[0].split(':')[1].split(';')[0];
        var max = bytes.length;
        var ia = new Uint8Array(max);
        for (var i = 0; i < max; i++)
            ia[i] = bytes.charCodeAt(i);
        return new Blob([ia], { type: mime });
    };
    var resize = function () {
        var width = image.width;
        var height = image.height;
        if (width > height) {
            if (width > maxSize) {
                height *= maxSize / width;
                width = maxSize;
            }
        } else {
            if (height > maxSize) {
                width *= maxSize / height;
                height = maxSize;
            }
        }
        canvas.width = width;
        canvas.height = height;
        canvas.getContext('2d').drawImage(image, 0, 0, width, height);
        var dataUrl = canvas.toDataURL('image/jpeg');
        return dataURItoBlob(dataUrl);
    };
    return new Promise(function (ok, no) {
        if (!file.type.match(/image.*/)) {
            no(new Error("Not an image"));
            return;
        }
        reader.onload = function (readerEvent) {
            image.onload = function () { return ok(resize()); };
            image.src = readerEvent.target.result;
        };
        reader.readAsDataURL(file);
    });
};

usage is like:

resizeImage({
    file: $image.files[0],
    maxSize: 500
}).then(function (resizedImage) {
    console.log("upload resized image")
}).catch(function (err) {
    console.error(err);
});

or (async/await):

const config = {
    file: $image.files[0],
    maxSize: 500
};
const resizedImage = await resizeImage(config)
console.log("upload resized image")

I created this simple function to help me. This makes my calls a lot easier to read that having inline an Get-WmiObject, Where-Object statements, etc.

function GetDiskSizeInfo($drive) {
    $diskReport = Get-WmiObject Win32_logicaldisk
    $drive = $diskReport | Where-Object { $_.DeviceID -eq $drive}

    $result = @{
        Size = $drive.Size
        FreeSpace = $drive.Freespace
    }
    return $result
}

$diskspace = GetDiskSizeInfo "C:"
write-host $diskspace.FreeSpace " " $diskspace.Size

If you don't mind hardcoding it you can do this ~> android:background="#eeeeee" and drop any hex color # you wish.

Looks like this....

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:layout_below="@+id/textView1"
    android:text="@string/ClickMe"
    android:background="#fff"/>

Use localStorage for that. It's persistent over sessions.

Writing :

localStorage['myKey'] = 'somestring'; // only strings

Reading :

var myVar = localStorage['myKey'] || 'defaultValue';

If you need to store complex structures, you might serialize them in JSON. For example :

Reading :

var stored = localStorage['myKey'];
if (stored) myVar = JSON.parse(stored);
else myVar = {a:'test', b: [1, 2, 3]};

Writing :

localStorage['myKey'] = JSON.stringify(myVar);

Note that you may use more than one key. They'll all be retrieved by all pages on the same domain.

Unless you want to be compatible with IE7, you have no reason to use the obsolete and small cookies.

You are using a wrong overload of the Html.ActionLink helper. What you think is routeValues is actually htmlAttributes! Just look at the generated HTML, you will see that this anchor's href property doesn't look as you expect it to look.

Here's what you are using:

@Html.ActionLink(
    "Reply",                                                  // linkText
    "BlogReplyCommentAdd",                                    // actionName
    "Blog",                                                   // routeValues
    new {                                                     // htmlAttributes
        blogPostId = blogPostId, 
        replyblogPostmodel = Model, 
        captchaValid = Model.AddNewComment.DisplayCaptcha 
    }
)

and here's what you should use:

@Html.ActionLink(
    "Reply",                                                  // linkText
    "BlogReplyCommentAdd",                                    // actionName
    "Blog",                                                   // controllerName
    new {                                                     // routeValues
        blogPostId = blogPostId, 
        replyblogPostmodel = Model, 
        captchaValid = Model.AddNewComment.DisplayCaptcha 
    },
    null                                                      // htmlAttributes
)

Also there's another very serious issue with your code. The following routeValue:

replyblogPostmodel = Model

You cannot possibly pass complex objects like this in an ActionLink. So get rid of it and also remove the BlogPostModel parameter from your controller action. You should use the blogPostId parameter to retrieve the model from wherever this model is persisted, or if you prefer from wherever you retrieved the model in the GET action:

public ActionResult BlogReplyCommentAdd(int blogPostId, bool captchaValid)
{
    BlogPostModel model = repository.Get(blogPostId);
    ...
}

As far as your initial problem is concerned with the wrong overload I would recommend you writing your helpers using named parameters:

@Html.ActionLink(
    linkText: "Reply",
    actionName: "BlogReplyCommentAdd",
    controllerName: "Blog",
    routeValues: new {
        blogPostId = blogPostId, 
        captchaValid = Model.AddNewComment.DisplayCaptcha
    },
    htmlAttributes: null
)

Now not only that your code is more readable but you will never have confusion between the gazillions of overloads that Microsoft made for those helpers.

city = 'Ribeir\xc3\xa3o Preto'
print city.decode('cp1252').encode('utf-8')

I have a solution to this. Actually it is a solution to a problem that arises after rotation(Rectangular image doesn't fit ImagView) but it covers your problem too.. Although this Solution has Animation for better or for worse

    int h,w;
    Boolean safe=true;

Getting the parameters of imageView is not possible at initialisation of activity To do so please refer to this solution OR set the dimensions at onClick of a Button Like this

    rotateButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            if(imageView.getRotation()/90%2==0){
                h=imageView.getHeight();
                w=imageView.getWidth();

            }
        .
        .//Insert the code Snippet below here 
       }

And the code to be run when we want to rotate ImageView

if(safe)     
imageView.animate().rotationBy(90).scaleX(imageView.getRotation()/90%2==0?(w*1.0f/h):1).scaleY(imageView.getRotation()/90%2==0?(w*1.0f/h):1).setDuration(2000).setInterpolator(new LinearInterpolator()).setListener(new Animator.AnimatorListener() {
                @Override
                public void onAnimationStart(Animator animation) {
                      safe=false;
                }

                @Override
                public void onAnimationEnd(Animator animation) {
                      safe=true;

                }

                @Override
                public void onAnimationCancel(Animator animation) {

                }

                @Override
                public void onAnimationRepeat(Animator animation) {

                }
            }).start();
        }
    });

This solution is sufficient for the Problem above.Although it will shrink the imageView even if it is not necessary(when height is smaller than Width).If it bothers you,you can add another ternary operator inside scaleX/scaleY.

>>> a = [1, 3, 5]
>>> b = [1, 3, 5, 8]
>>> c = [3, 5, 9]
>>> set(a) <= set(b)
True
>>> set(c) <= set(b)
False

>>> a = ['yes', 'no', 'hmm']
>>> b = ['yes', 'no', 'hmm', 'well']
>>> c = ['sorry', 'no', 'hmm']
>>> 
>>> set(a) <= set(b)
True
>>> set(c) <= set(b)
False

table() function is a good way to go, as Chase suggested. If you are analyzing a large dataset, an alternative way is to use .N function in datatable package.

Make sure you installed the data table package by

install.packages("data.table")

Code:

# Import the data.table package
library(data.table)

# Generate a data table object, which draws a number 10^7 times  
# from 1 to 10 with replacement
DT<-data.table(x=sample(1:10,1E7,TRUE))

# Count Frequency of each factor level
DT[,.N,by=x]

You can initialise the whole result list in the top level call to mergesort:

result = [0]*len(x)   # replace 0 with a suitable default element if necessary. 
                      # or just copy x (result = x[:])

Then for the recursive calls you can use a helper function to which you pass not sublists, but indices into x. And the bottom level calls read their values from x and write into result directly.

That way you can avoid all that poping and appending which should improve performance.

Leave you stuff there and Try the following as well:

Start > Right-click on My computer > Properties > Advanced system settings > Environment Variables > look for variable name called "Path" in the lower box

set path value value as: (you can just add it to the starting of line, don't forgot semi column in between )

c:\Program Files\java\jre7\bin

Downcasting is allowed when there is a possibility that it succeeds at run time:

Object o = getSomeObject(),
String s = (String) o; // this is allowed because o could reference a String

In some cases this will not succeed:

Object o = new Object();
String s = (String) o; // this will fail at runtime, because o doesn't reference a String

When a cast (such as this last one) fails at runtime a ClassCastException will be thrown.

In other cases it will work:

Object o = "a String";
String s = (String) o; // this will work, since o references a String

Note that some casts will be disallowed at compile time, because they will never succeed at all:

Integer i = getSomeInteger();
String s = (String) i; // the compiler will not allow this, since i can never reference a String.

This solution is for usort() with an easy-to-remember notation for multidimensional sorting. The spaceship operator <=> is used, which is available from PHP 7.

usort($in,function($a,$b){
  return $a['first']   <=> $b['first']  //first asc
      ?: $a['second']  <=> $b['second'] //second asc
      ?: $b['third']   <=> $a['third']  //third desc (a b swapped!)
      //etc
  ;
});

Examples:

$in = [
  ['firstname' => 'Anton', 'surname' => 'Gruber', 'birthdate' => '03.08.1967', 'rank' => 3],
  ['firstname' => 'Anna', 'surname' => 'Egger', 'birthdate' => '04.01.1960', 'rank' => 1],
  ['firstname' => 'Paul', 'surname' => 'Mueller', 'birthdate' => '15.10.1971', 'rank' => 2],
  ['firstname' => 'Marie', 'surname' => 'Schmidt ', 'birthdate' => '24.12.1963', 'rank' => 2],
  ['firstname' => 'Emma', 'surname' => 'Mueller', 'birthdate' => '23.11.1969', 'rank' => 2],
];

first task: Order By rank asc, surname asc

usort($in,function($a,$b){
  return $a['rank']      <=> $b['rank']     //first asc
      ?: $a['surname']   <=> $b['surname']  //second asc
  ;
});

second task: Order By rank desc, surname asc, firstmame asc

usort($in,function($a,$b){
  return $b['rank']      <=> $a['rank']       //first desc
      ?: $a['surname']   <=> $b['surname']    //second asc
      ?: $a['firstname'] <=> $b['firstname']  //third asc
  ;
});

third task: Order By rank desc, birthdate asc

The date cannot be sorted in this notation. It is converted with strtotime.

usort($in,function($a,$b){
  return $b['rank']      <=> $a['rank']       //first desc
      ?: strtotime($a['birthdate']) <=> strtotime($b['birthdate'])    //second asc
  ;
});

I figured out that this behaves like a mousedown event:

button:active:hover {}

There are two major purposes of hashing functions:

• to disperse data points uniformly into n bits.
• to securely identify the input data.

It's impossible to recommend a hash without knowing what you're using it for.

If you're just making a hash table in a program, then you don't need to worry about how reversible or hackable the algorithm is... SHA-1 or AES is completely unnecessary for this, you'd be better off using a variation of FNV. FNV achieves better dispersion (and thus fewer collisions) than a simple prime mod like you mentioned, and it's more adaptable to varying input sizes.

If you're using the hashes to hide and authenticate public information (such as hashing a password, or a document), then you should use one of the major hashing algorithms vetted by public scrutiny. The Hash Function Lounge is a good place to start.

Since switch case always returns a single object, we can directly print its result:

puts case a
     when 0
        "It's zero"
     when 1
        "It's one"
     end

and select Disable Security Check (/GS-)
