In Eclipse Photon navigate to Windows > Preferences > Maven > User Settings > User Setting

For "User settings" Browse to the settings.xml of the maven. ex. in my case maven it is located on the path C:\Program Files\Apache Software Distribution\apache-maven-3.5.4\conf\Settings.xml

Depending on the Settings.xml the Local Repository gets automatically configured to the specified location.

This answer is based on the same 'theory' that is outlined well by this answer

I'm adding this answer as:
-- None of the other options fit the 'uniformity' need 'spot-on' (or not obviously-clearly so). (Noting to get the planet like distribution looking behavior particurally wanted in the original ask, you just reject from the finite list of the k uniformly created points at random (random wrt the index count in the k items back).)
--The closest other impl forced you to decide the 'N' by 'angular axis', vs. just 'one value of N' across both angular axis values ( which at low counts of N is very tricky to know what may, or may not matter (e.g. you want '5' points -- have fun ) )
--Furthermore, it's very hard to 'grok' how to differentiate between the other options without any imagery, so here's what this option looks like (below), and the ready-to-run implementation that goes with it.

with N at 20:

and then N at 80:

here's the ready-to-run python3 code, where the emulation is that same source: " http://web.archive.org/web/20120421191837/http://www.cgafaq.info/wiki/Evenly_distributed_points_on_sphere " found by others. ( The plotting I've included, that fires when run as 'main,' is taken from: http://www.scipy.org/Cookbook/Matplotlib/mplot3D )

This worked for me. All I had to do is uninstall mysql2 gem and install it again using the below commands

gem uninstall mysql2
gem install mysql2 -v '0.3.18' -- --with-mysql-config=/usr/local/Cellar/[email protected]/5.7.28/bin/mysql_config

Well, one practical use I've found out is reducing boiler plate code. For example:

void process_z_vec(vector<int>& vec)
{
  auto print_2d = [](const vector<int>& board, int bsize)
  {
    for(int i = 0; i<bsize; i++)
    {
      for(int j=0; j<bsize; j++)
      {
        cout << board[bsize*i+j] << " ";
      }
      cout << "\n";
    }
  };
  // Do sth with the vec.
  print_2d(vec,x_size);
  // Do sth else with the vec.
  print_2d(vec,y_size);
  //... 
}

Without lambda, you may need to do something for different bsize cases. Of course you could create a function but what if you want to limit the usage within the scope of the soul user function? the nature of lambda fulfills this requirement and I use it for that case.

If you just want to know about your screen width, you can just search for "smallest screen width" in your developer options. You can even edit it.

In my case, I was getting this error because my table had

varchar(50)

but I was injecting 67 character long string, which resulted in thi error. Changing it to

varchar(255)

fixed the problem.

I also faced the same issue today in my running code. Well, I found a lot of answers here. But the important thing I want to mention is that this error message is quite ambiguous and doesn't explicitly point out the exact error.

Some faced it due to browser extensions, some due to incorrect URL patterns and I faced this due to an error in my formGroup instance used in a pop-up in that screen. So, I would suggest everyone that before making any new changes in your code, please debug your code and verify that you don't have any such errors. You will certainly find the actual reason by debugging.

If nothing else works then check your URL as that is the most common reason for this issue.

You just need to inject ActivatedRoute in constructor and then just access params or queryParams over it

constructor(private route:ActivatedRoute){}
ngOnInit(){
        this.route.queryParams.subscribe(params=>{
        let username=params['username'];
      });
 }

In Some cases it doesn't give anything in NgOnInit ...maybe because of init call before initialization of params in this case you can achieve this by asking observable to wait for some time by function debounceTime(1000)

e.g=>

 constructor(private route:ActivatedRoute){}
    ngOnInit(){
            this.route.queryParams.debounceTime(100).subscribe(params=>{
            let username=params['username'];
          });
     }

debounceTime() Emits a value from source observable only after particular time span passed without another source emission

The modern way:

new URL("http://example.com/aa/bb/")

Returns an object with properties hostname and pathname, along with a few others.

The first argument is a relative or absolute URL; if it's relative, then you need to specify the second argument (the base URL). For example, for a URL relative to the current page:

new URL("/aa/bb/", location)

In addition to browsers, this API is also available in Node.js since v7, through require('url').URL.

Some RFID chips are read-write, the majority are read-only. You can find out if your chip is read-only by checking the datasheet.

@klode's answer is right.

However, you are supposed to set another response header to make your header accessible to others.

Example:

First, you add 'page-size' in response header

response.set('page-size', 20);

Then, all you need to do is expose your header

response.set('Access-Control-Expose-Headers', 'page-size')

No, only native iOS applications support push notifications.

UPDATE:
Mac OS X 10.9 & Safari 7 websites can now also send push notifications, but this still does not apply to iOS. Read the Notification Programming Guide for Websites. Also check out WWDC 2013 Session 614.

You can use the following:

MainActivity.this.getApplicationContext();

MainActivity.java:

...
public class MainActivity ... {
    static MainActivity ma;
...
    public void onCreate(Bundle b) {
         super...
         ma=this;
         ...

Any other class:

public ...
    public ANY_METHOD... {
         Context c = MainActivity.ma.getApplicationContext();

I found the answer on the web:

Dim fsT As Object
Set fsT = CreateObject("ADODB.Stream")
fsT.Type = 2 'Specify stream type - we want To save text/string data.
fsT.Charset = "utf-8" 'Specify charset For the source text data.
fsT.Open 'Open the stream And write binary data To the object

fsT.SaveToFile sFileName, 2 'Save binary data To disk

Certainly not as I expected...

Your Delivery class is internal (the default visibility for classes), however the property (and presumably the containing class) are public, so the property is more accessible than the Delivery class. You need to either make Delivery public, or restrict the visibility of the thelivery property.

@Gadde - your answer was very helpful. Thank you! I needed a "Maps"-like zoom for a div and was able to produce the feel I needed with your post. My criteria included the need to have the click repeat and continue to zoom out/in with each click. Below is my final result.

    var currentZoom = 1.0;

    $(document).ready(function () {
        $('#btn_ZoomIn').click(
            function () {
                $('#divName').animate({ 'zoom': currentZoom += .1 }, 'slow');
            })
        $('#btn_ZoomOut').click(
            function () {
                $('#divName').animate({ 'zoom': currentZoom -= .1 }, 'slow');
            })
        $('#btn_ZoomReset').click(
            function () {
                currentZoom = 1.0
                $('#divName').animate({ 'zoom': 1 }, 'slow');
            })
    });

You can do this using a group by:

select id, addressCode
from t
group by id, addressCode
having min(address) <> max(address)

Another way of writing this may seem clearer, but does not perform as well:

select id, addressCode
from t
group by id, addressCode
having count(distinct address) > 1

First of all, the keys are managed at https://www.google.com/recaptcha/admin#list

I ran into this error because I'm using the same key on a few different domains and I had forgotten to add one of the domains to the key.

After adding my site it took a minute or two (most likely because of cache) for things to work normally again.

None of those work for me.

You could also use Artifactory Query Language to get the latest artifact.

The following shell script is just an example. It uses 'items.find()' (which is available in the non-Pro version), e.g. items.find({ "repo": {"$eq":"my-repo"}, "name": {"$match" : "my-file*"}}) that searches for files that have a repository name equal to "my-repo" and match all files that start with "my-file". Then it uses the shell JSON parser ./jq to extract the latest file by sorting by the date field 'updated'. Finally it uses wget to download the artifact.

#!/bin/bash

# Artifactory settings
host="127.0.0.1"
username="downloader"
password="my-artifactory-token"

# Use Artifactory Query Language to get the latest scraper script (https://www.jfrog.com/confluence/display/RTF/Artifactory+Query+Language)
resultAsJson=$(curl -u$username:"$password" -X POST  http://$host/artifactory/api/search/aql -H "content-type: text/plain" -d 'items.find({ "repo": {"$eq":"my-repo"}, "name": {"$match" : "my-file*"}})')

# Use ./jq to pars JSON
latestFile=$(echo $resultAsJson | jq -r '.results | sort_by(.updated) [-1].name')

# Download the latest scraper script
wget -N -P ./libs/ --user $username --password $password http://$host/artifactory/my-repo/$latestFile

You can use finish() method or you can use:

android:noHistory="true"

And then there is no need to call finish() anymore.

<activity android:name=".ClassName" android:noHistory="true" ... />

Try this,to retrieve all files inside folder and sub-folder

public static void main(String[]args)
    {
        File curDir = new File(".");
        getAllFiles(curDir);
    }
    private static void getAllFiles(File curDir) {

        File[] filesList = curDir.listFiles();
        for(File f : filesList){
            if(f.isDirectory())
                getAllFiles(f);
            if(f.isFile()){
                System.out.println(f.getName());
            }
        }

    }

To retrieve files/folder only

public static void main(String[]args)
    {
        File curDir = new File(".");
        getAllFiles(curDir);
    }
    private static void getAllFiles(File curDir) {

        File[] filesList = curDir.listFiles();
        for(File f : filesList){
            if(f.isDirectory())
                System.out.println(f.getName());
            if(f.isFile()){
                System.out.println(f.getName());
            }
        }

    }

I added +/- 10-15% efficiency to the selected answer by minor code refactoring and moving the recursive function outside of the function namespace.

See my question: Are namespaced functions reevaluated on every call? for why this slows nested functions down.

function _flatten (target, obj, path) {
  var i, empty;
  if (obj.constructor === Object) {
    empty = true;
    for (i in obj) {
      empty = false;
      _flatten(target, obj[i], path ? path + '.' + i : i);
    }
    if (empty && path) {
      target[path] = {};
    }
  } 
  else if (obj.constructor === Array) {
    i = obj.length;
    if (i > 0) {
      while (i--) {
        _flatten(target, obj[i], path + '[' + i + ']');
      }
    } else {
      target[path] = [];
    }
  }
  else {
    target[path] = obj;
  }
}

function flatten (data) {
  var result = {};
  _flatten(result, data, null);
  return result;
}

See benchmark.

use the String.Trim() function.

string foo = "   hello ";
string bar = foo.Trim();

Console.WriteLine(bar); // writes "hello"

Here is a link to Adobe's reference material

http://www.adobe.com/devnet/pdf/pdf_reference.html

You should know though that PDF is only about presentation, not structure. Parsing will not come easy.

CREATE [TEMPORARY] TABLE [IF NOT EXISTS] tbl_name
[(create_definition,...)]
[table_options]
select_statement

Example :

CREATE TEMPORARY TABLE IF NOT EXISTS mytable
(id int(11) NOT NULL, PRIMARY KEY (id)) ENGINE=MyISAM;
INSERT IGNORE INTO mytable SELECT id FROM table WHERE xyz;

In your current code, what Dictionary.update() does is that it updates (update means the value is overwritten from the value for same key in passed in dictionary) the keys in current dictionary with the values from the dictionary passed in as the parameter to it (adding any new key:value pairs if existing) . A single flat dictionary does not satisfy your requirement , you either need a list of dictionaries or a dictionary with nested dictionaries.

If you want a list of dictionaries (where each element in the list would be a diciotnary of a entry) then you can make case_list as a list and then append case to it (instead of update) .

Example -

case_list = []
for entry in entries_list:
    case = {'key1': entry[0], 'key2': entry[1], 'key3':entry[2] }
    case_list.append(case)

Or you can also have a dictionary of dictionaries with the key of each element in the dictionary being entry1 or entry2 , etc and the value being the corresponding dictionary for that entry.

case_list = {}
for entry in entries_list:
    case = {'key1': value, 'key2': value, 'key3':value }
    case_list[entryname] = case  #you will need to come up with the logic to get the entryname.

Adding this for diversity and clean approach.

This code uses functional style approach. I have used onresize instead of addEventListener as mentioned in other answers.

import { useState, useEffect } from "react";

export default function App() {
  const [size, setSize] = useState({
    x: window.innerWidth,
    y: window.innerHeight
  });
  const updateSize = () =>
    setSize({
      x: window.innerWidth,
      y: window.innerHeight
    });
  useEffect(() => (window.onresize = updateSize), []);
  return (
    <>
      <p>width is : {size.x}</p>
      <p>height is : {size.y}</p>
    </>
  );
}

Use System.Windows.Forms.SystemInformation.UserName for the actually logged in user as Environment.UserName still returns the account being used by the current process.

Enabling Tracing may be a better alternative to the Windows Event Log. This gave me the information I needed to fix my own WebService.

All you need is to create two layouts:

1. an empty layout

2. main layout

Then write the code below in _viewStart file:

@{
   if (Request.IsAjaxRequest())
   {
      Layout = "~/Areas/Dashboard/Views/Shared/_emptyLayout.cshtml";
   }
   else
   {
      Layout = "~/Areas/Dashboard/Views/Shared/_Layout.cshtml";
   }
 }

of course, maybe it is not the best solution

Excerpt from the package description

Package java.util.concurrent.atomic description: A small toolkit of classes that support lock-free thread-safe programming on single variables.[...]

The specifications of these methods enable implementations to employ efficient machine-level atomic instructions that are available on contemporary processors.[...]

Instances of classes AtomicBoolean, AtomicInteger, AtomicLong, and AtomicReference each provide access and updates to a single variable of the corresponding type.[...]

The memory effects for accesses and updates of atomics generally follow the rules for volatiles:

• get has the memory effects of reading a volatile variable.
• set has the memory effects of writing (assigning) a volatile variable.
• weakCompareAndSet atomically reads and conditionally writes a variable, is ordered with respect to other memory operations on that variable, but otherwise acts as an ordinary non-volatile memory operation.
• compareAndSet and all other read-and-update operations such as getAndIncrement have the memory effects of both reading and writing volatile variables.

Not tested but you can give a try. Tested and working. I hope you can play with AutoSizeMode of DataGridViewColum to achieve what you need.

Try setting

dataGridView1.DataSource = yourdatasource;<--set datasource before you set AutoSizeMode

//Set the following properties after setting datasource
dataGridView1.Columns[0].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
dataGridView1.Columns[1].AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCells;
dataGridView1.Columns[2].AutoSizeMode = DataGridViewAutoSizeColumnMode.Fill;

This should work

|| returns a boolean value by OR'ing two values (Thats why its known as a LOGICAL or)

IE:

if (A || B) 

Would return true if either A or B is true, or false if they are both false.

| is an operator that performs a bitwise operation on two values. To better understand bitwise operations, you can read here:

http://en.wikipedia.org/wiki/Bitwise_operation

If you want to use a column with 24/11/15 (for 24th November 2015) in your Pivot that will sort correctly, you can make sure it is properly formatted by doing the following - highlight the column, go to Data – Text to Columns – click Next twice, then select “Date” and use the default of DMY (or select as applicable to your data) and click ok

When you pivot now you should see it sorting properly as we have properly formatted that column to be a date field so Excel can work with it

You can use any of the two based on your need:

Field[] fields = ClassName.class.getFields(); // returns inherited members but not private members.
Field[] fields = ClassName.class.getDeclaredFields(); // returns all members including private members but not inherited members.

To filter only the public fields from the above list (based on requirement) use below code:

List<Field> fieldList = Arrays.asList(fields).stream().filter(field -> Modifier.isPublic(field.getModifiers())).collect(
    Collectors.toList());

In My case the issue was fixed by changing the solution platform from AnyCPU to x86.

The latest google api docs document how to write to a spreadsheet with python but it's a little difficult to navigate to. Here is a link to an example of how to append.

The following code is my first successful attempt at appending to a google spreadsheet.

to see changes that are not merged, I did this:

git checkout experiment
git merge --no-commit master

git diff --cached

Note: This shows changes in master that are not in experiment.

Don't forget to:

git merge --abort

When you're done lookin.

You do not need to user where clause while ordering the data alphabetically. here is my code

SELECT * FROM tbl_name ORDER BY field_name

that's it. It return the data in alphabetical order ie; From A to Z. :)

To get all the values from a list of dictionaries, use the following code :

list = [{'text': 1, 'b': 2}, {'text': 3, 'd': 4}, {'text': 5, 'f': 6}]
subtitle=[]
for value in list:
   subtitle.append(value['text'])

And for comedic value:

label.text = [NSString stringWithFormat:@"%@", [NSNumber numberWithInt:count]];

(Though it could be useful if one day you're dealing with NSNumber's)

There is a pseudocolumn called %%physloc%% that shows the physical address of the row.

See Equivalent of Oracle's RowID in SQL Server

This will be possible with setiosflags(ios::showpoint).

You told your repository to rebase. It looks like you were on a commit (identified by SHA 9c168a5) and then did git rebase master or git pull --rebase master.

You are rebasing the branch master onto that commit. You can end the rebase via git rebase --abort. This would put back at the state that you were at before you started rebasing.

If you are releasing, use the keystore you used to export your app with and not the debug.keystore.

You could use the CSS3 background-size property for this.

.header .logo {
background-size: 100%;
}

@user20877984's answer is excellent. Since they summed it up far better than my previous answer, here is my (posibly still shoddy) attempt at an application of the concept:

Using do.call in a basic fashion:

powvalues <- list(power=0.9,delta=2)
do.call(power.t.test,powvalues)

Working on a full data set:

# get the example data
df <- data.frame(delta=c(1,1,2,2), power=c(.90,.85,.75,.45))

#> df
#  delta power
#1     1  0.90
#2     1  0.85
#3     2  0.75
#4     2  0.45

lapply the power.t.test function to each of the rows of specified values:

result <- lapply(
  split(df,1:nrow(df)),
  function(x) do.call(power.t.test,x)
)

> str(result)
List of 4
 $ 1:List of 8
  ..$ n          : num 22
  ..$ delta      : num 1
  ..$ sd         : num 1
  ..$ sig.level  : num 0.05
  ..$ power      : num 0.9
  ..$ alternative: chr "two.sided"
  ..$ note       : chr "n is number in *each* group"
  ..$ method     : chr "Two-sample t test power calculation"
  ..- attr(*, "class")= chr "power.htest"
 $ 2:List of 8
  ..$ n          : num 19
  ..$ delta      : num 1
  ..$ sd         : num 1
  ..$ sig.level  : num 0.05
  ..$ power      : num 0.85
... ...

Personally (and given what I know, i.e., Java and axis), I'd generate a Java data model from the .xsd files (Axis 2 can do this), and then add an interface to describe my web service that uses that model, and then generate a WSDL from that interface.

Because .NET has all these features as well, it must be possible to do all this in that ecosystem as well.

Yes, you can!))

Disclaimer: This is not a solution, it is more of a hack to test out something. User-defined functions cannot be used to perform actions that modify the database state.

I found one way to make INSERT, UPDATE or DELETE in function using xp_cmdshell.

So you need just to replace the code inside @sql variable.

CREATE FUNCTION [dbo].[_tmp_func](@orderID NVARCHAR(50))
RETURNS INT
AS
BEGIN
DECLARE @sql varchar(4000), @cmd varchar(4000)
SELECT @sql = 'INSERT INTO _ord (ord_Code) VALUES (''' + @orderID + ''') '
SELECT @cmd = 'sqlcmd -S ' + @@servername +
              ' -d ' + db_name() + ' -Q "' + @sql + '"'
EXEC master..xp_cmdshell @cmd, 'no_output'
RETURN 1
END

This might be seen as a little complex but does exactly what you want

SELECT 
  DISTINCT(p.`ProductID`) AS ProductID,
  SUM(pl.CashAmount) AS Cash,
  SUM(pr.CashAmount) AS `Check`,
  SUM(px.CashAmount) AS `Credit Card`,
  SUM(pl.CashAmount) + SUM(pr.CashAmount) +SUM(px.CashAmount) AS Amount
FROM
  `payments` AS p 
  LEFT JOIN (SELECT ProductID,PaymentMethod , IFNULL(Amount,0) AS CashAmount FROM payments WHERE PaymentMethod = 'Cash' GROUP BY ProductID , PaymentMethod ) AS pl 
    ON pl.`PaymentMethod` = p.`PaymentMethod` AND pl.ProductID = p.`ProductID`
  LEFT JOIN (SELECT ProductID,PaymentMethod , IFNULL(Amount,0) AS CashAmount FROM payments WHERE PaymentMethod = 'Check' GROUP BY ProductID , PaymentMethod) AS pr 
    ON pr.`PaymentMethod` = p.`PaymentMethod` AND pr.ProductID = p.`ProductID`
  LEFT JOIN (SELECT ProductID, PaymentMethod , IFNULL(Amount,0) AS CashAmount FROM payments WHERE PaymentMethod = 'Credit Card' GROUP BY ProductID , PaymentMethod) AS px 
    ON px.`PaymentMethod` = p.`PaymentMethod` AND px.ProductID = p.`ProductID`
GROUP BY p.`ProductID` ;

Output

ProductID | Cash | Check | Credit Card | Amount
-----------------------------------------------
    3     | 20   |  15   |   25        |  60
    4     | 5    |  6    |   7         |  18

For Apache HttpClient 4.4:

HttpClientBuilder b = HttpClientBuilder.create();

SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(null, new TrustStrategy() {
    public boolean isTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {
        return true;
    }
}).build();
b.setSslcontext( sslContext);

// or SSLConnectionSocketFactory.getDefaultHostnameVerifier(), if you don't want to weaken
HostnameVerifier hostnameVerifier = SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER;

SSLConnectionSocketFactory sslSocketFactory = new SSLConnectionSocketFactory(sslContext, hostnameVerifier);
Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()
        .register("http", PlainConnectionSocketFactory.getSocketFactory())
        .register("https", sslSocketFactory)
        .build();

// allows multi-threaded use
PoolingHttpClientConnectionManager connMgr = new PoolingHttpClientConnectionManager( socketFactoryRegistry);
b.setConnectionManager( connMgr);

HttpClient client = b.build();

This is extracted from our actual working implementation.

The other answers are popular, but for HttpClient 4.4 they don't work. I spent hours trying & exhausting possibilities, but there seems to have been extremely major API change & relocation at 4.4.

Hope that helps!

I came across this post while trying to figure out how to get OrderedDict to work. PyDev for Eclipse couldn't find OrderedDict at all, so I ended up deciding to make a tuple of my dictionary's key values as I would like them to be ordered. When I needed to output my list, I just iterated through the tuple's values and plugged the iterated 'key' from the tuple into the dictionary to retrieve my values in the order I needed them.

example:

test_dict = dict( val1 = "hi", val2 = "bye", val3 = "huh?", val4 = "what....")
test_tuple = ( 'val1', 'val2', 'val3', 'val4')
for key in test_tuple: print(test_dict[key])

It's a tad cumbersome, but I'm pressed for time and it's the workaround I came up with.

note: the list of lists approach that somebody else suggested does not really make sense to me, because lists are ordered and indexed (and are also a different structure than dictionaries).

let res = /^[a-zA-Z]+$/.test('sfjd');
console.log(res);

Note: If you have any punctuation marks or anything, those are all invalid too. Dashes and underscores are invalid. \w covers a-zA-Z and some other word characters. It all depends on what you need specifically.

Use strftime:

strftime("%F %T");

• %F is the same as %Y-%m-%d.

• %T is the same as %H:%M:%S.

Here's a demo on ideone.

I discovered that the accepted answer actually doesn't always work, because \\Z may occur in the file. Another problem is that if you don't have the correct charset a whole bunch of unexpected things may happen which may cause the scanner to read only a part of the file.

The solution is to use a delimiter which you are certain will never occur in the file. However, this is theoretically impossible. What we CAN do, is use a delimiter that has such a small chance to occur in the file that it is negligible: such a delimiter is a UUID, which is natively supported in Java.

String content = new Scanner(file, "UTF-8")
    .useDelimiter(UUID.randomUUID().toString()).next();

If you want to copy files and see a "progress" I suggest the script below in Batch that I used from another script as a base

I used a progress bar and a percentage while the script copies the game files Nuclear throne:

I think the most significant problem is that you're incrementing code as you read stuff in, and then returning the final value of code, i.e. you'll be returning a pointer to the end of the string. You probably want to make a copy of code before the loop, and return that instead.

Also, C strings need to be null-terminated. You need to make sure that you place a '\0' directly after the final character that you read in.

Note: You could just use fgets() to get the entire line in one hit.

select sys_context('USERENV','INSTANCE_NAME') from dual;

&

select instance_name from v$instance;

will give you the instance name. You can also use select * from global_name; to view the global name of the instance.

You can write a quick script that erases a single #include directive, compiles the projects, and logs the name in the #include and the file it was removed from in the case that no compilation errors occurred.

Let it run during the night, and the next day you will have a 100% correct list of include files you can remove.

Sometimes brute-force just works :-)

edit: and sometimes it doesn't :-). Here's a bit of information from the comments:

1. Sometimes you can remove two header files separately, but not both together. A solution is to remove the header files during the run and not bring them back. This will find a list of files you can safely remove, although there might a solution with more files to remove which this algorithm won't find. (it's a greedy search over the space of include files to remove. It will only find a local maximum)
2. There may be subtle changes in behavior if you have some macros redefined differently depending on some #ifdefs. I think these are very rare cases, and the Unit Tests which are part of the build should catch these changes.

To get the port number in your code you can use the following:

@Autowired
Environment environment;

@GetMapping("/test")
String testConnection(){
    return "Your server is up and running at port: "+environment.getProperty("local.server.port");      
}

To understand the Environment property you can go through this Spring boot Environment

# Pseudo code
# Corners in ax,ay,bx,by,dx,dy
# Point in x, y

bax = bx - ax
bay = by - ay
dax = dx - ax
day = dy - ay

if ((x - ax) * bax + (y - ay) * bay < 0.0) return false
if ((x - bx) * bax + (y - by) * bay > 0.0) return false
if ((x - ax) * dax + (y - ay) * day < 0.0) return false
if ((x - dx) * dax + (y - dy) * day > 0.0) return false

return true

If I understand correctly, you want Base functionality to always be performed, while a piece of it should be left to implementations.

You might get helped by the 'template method' design pattern.

Base = function() {}
Base.prototype.do = function() { 
    // .. prologue code
    this.impldo(); 
    // epilogue code 
}
// note: no impldo implementation for Base!

derived = new Base();
derived.impldo = function() { /* do derived things here safely */ }

Here is a way to transform a date string with a time of day to a date object. For example to convert "20/10/2020 18:11:25" ("DD/MM/YYYY HH:MI:SS" format) to a date object

    function newUYDate(pDate) {
      let dd = pDate.split("/")[0].padStart(2, "0");
      let mm = pDate.split("/")[1].padStart(2, "0");
      let yyyy = pDate.split("/")[2].split(" ")[0];
      let hh = pDate.split("/")[2].split(" ")[1].split(":")[0].padStart(2, "0");
      let mi = pDate.split("/")[2].split(" ")[1].split(":")[1].padStart(2, "0");
      let secs = pDate.split("/")[2].split(" ")[1].split(":")[2].padStart(2, "0");
    
      mm = (parseInt(mm) - 1).toString(); // January is 0
    
      return new Date(yyyy, mm, dd, hh, mi, secs);
    }

or you can simply use

def question_params

  params.require(:question).permit(team_ids: [])

end

Upper div use higher z-index and lower div use lower z-index then use absolute/fixed/relative position

This is rather easy to achieve by making a dataset with a text-query like this:

SELECT 'Item1'
UNION
SELECT 'Item2'
UNION
SELECT 'Item3'
UNION
SELECT 'Item4'
UNION
SELECT 'ItemN'

The query should return all items that can be selected.

grep -nr "search string" directory

This gives you the line with the line number.

As noted by VonC, this has already been included in git 2.16+. Unfortunately, the name of the option (--ignore-cr-at-eol) differs from the one used by GNU diff that I'm used to (--strip-trailing-cr).

When I was confronted with this problem, my solution was to invoke GNU diff instead of git's built-in diff, because my git is older than 2.16. I did that using this command line:

GIT_EXTERNAL_DIFF='diff -u --strip-trailing-cr "$2" "$5";true;#' git diff --ext-diff

That allows using --strip-trailing-cr and any other GNU diff options.

There's also this other way:

git difftool -y -x 'diff -u --strip-trailing-cr'

but it doesn't use the configured pager settings, which is why I prefer the former.

Try using the not() method instead of the :not() selector.

$(".content a").click(function() {
    $(".content a").not(this).hide("slow");
});

mod = a % b

This stores the result of a mod b in the variable mod.

And you are right, 15 mod 4 is 3, which is exactly what python returns:

>>> 15 % 4
3

a %= b is also valid.

HI im going to leave this here cz i cant comment due to restrictions but i found AlexFitiskin's answer perfect, but a small correction was needed

document.getElementById('here').innerHTML = data.name; 

This needed to be changed to

document.getElementById('here').innerHTML = data.n;

I know that after five years the owner of the post will not find it of any importance but this is for people who might come across in the future .

the following code is for making the same y axis limit on two subplots

f ,ax = plt.subplots(1,2,figsize = (30, 13),gridspec_kw={'width_ratios': [5, 1]})
df.plot(ax = ax[0], linewidth = 2.5)
ylim = [lower_limit,upper_limit]
ax[0].set_ylim(ylim)
ax[1].hist(data,normed =1, bins = num_bin, color = 'yellow' ,alpha = 1) 
ax[1].set_ylim(ylim)

just a reminder, plt.hist(range=[low, high]) the histogram auto crops the range if the specified range is larger than the max&min of the data points. So if you want to specify the y-axis range number, i prefer to use set_ylim

The simplest solutions are the best, so You just need:

var list = document.getElementById('list');_x000D_
while (list.firstChild) {_x000D_
    list.removeChild(list.firstChild);_x000D_
}

<select id="list">_x000D_
  <option value="0">0</option>_x000D_
  <option value="1">1</option>_x000D_
</select>

Encapsulation: Is hiding unwanted/un-expected/propriety implementation details from the actual users of object. e.g.

List<string> list = new List<string>();
list.Sort(); /* Here, which sorting algorithm is used and hows its 
implemented is not useful to the user who wants to perform sort, that's 
why its hidden from the user of list. */

Abstraction: Is a way of providing generalization and hence a common way to work with objects of vast diversity. e.g.

class Aeroplane : IFlyable, IFuelable, IMachine
{ // Aeroplane's Design says:
  // Aeroplane is a flying object
  // Aeroplane can be fueled
  // Aeroplane is a Machine
}
// But the code related to Pilot, or Driver of Aeroplane is not bothered 
// about Machine or Fuel. Hence,
// pilot code:
IFlyable flyingObj = new Aeroplane();
flyingObj.Fly();
// fighter Pilot related code
IFlyable flyingObj2 = new FighterAeroplane();
flyingObj2.Fly();
// UFO related code 
IFlyable ufoObj = new UFO();
ufoObj.Fly();
// **All the 3 Above codes are genaralized using IFlyable,
// Interface Abstraction**
// Fly related code knows how to fly, irrespective of the type of 
// flying object they are.

// Similarly, Fuel related code:
// Fueling an Aeroplane
IFuelable fuelableObj = new Aeroplane();
fuelableObj.FillFuel();
// Fueling a Car
IFuelable fuelableObj2 = new Car(); // class Car : IFuelable { }
fuelableObj2.FillFuel();

// ** Fueling code does not need know what kind of vehicle it is, so far 
// as it can Fill Fuel**

You can delete the selected item with this:

$("#selectBox option:selected").remove();

This is useful if you have a list and not a dropdown.

The most simple and native way it's to use CURL directly.

This works for me :

<?php
$login = 'login';
$password = 'password';
$url = 'http://your.url';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, "$login:$password");
$result = curl_exec($ch);
curl_close($ch);  
echo($result);

Also very late, but here is an answer from Karvy1 that worked well for me if you don't have pandas >=0.25 version: https://stackoverflow.com/a/52511166/10740287

For the example above you may write:

data = [(row.subject, row.trial_num, sample) for row in df.itertuples() for sample in row.samples]
data = pd.DataFrame(data, columns=['subject', 'trial_num', 'samples'])

Speed test:

%timeit data = pd.DataFrame([(row.subject, row.trial_num, sample) for row in df.itertuples() for sample in row.samples], columns=['subject', 'trial_num', 'samples'])

1.33 ms ± 74.8 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

%timeit data = df.set_index(['subject', 'trial_num'])['samples'].apply(pd.Series).stack().reset_index()

4.9 ms ± 189 µs per loop (mean ± std. dev. of 7 runs, 100 loops each)

%timeit data = pd.DataFrame({col:np.repeat(df[col].values, df['samples'].str.len())for col in df.columns.drop('samples')}).assign(**{'samples':np.concatenate(df['samples'].values)})

1.38 ms ± 25 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

If you need to do many append operations to build a large string, you can use StringIO or cStringIO. The interface is like a file. ie: you write to append text to it.

If you're just appending two strings then just use +.

In addition to Richard Cresswells and dpbradleys answer: If you neither want to create a TNS name nor the '//123.45.67.89:1521/Test' input works (some configurations wont), you can put

(DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 123.45.67.89)(PORT = 1521)) (CONNECT_DATA = (SID = TEST)(SERVER = DEDICATED)))

(as one line) into the 'database' section of the login dialog.

Update April 2019

jQuery isn't needed for cookie reading/manipulation, so don't use the original answer below.

Go to https://github.com/js-cookie/js-cookie instead, and use the library there that doesn't depend on jQuery.

Basic examples:

// Set a cookie
Cookies.set('name', 'value');

// Read the cookie
Cookies.get('name') => // => 'value'

See the docs on github for details.

Before April 2019 (old)

See the plugin:

https://github.com/carhartl/jquery-cookie

You can then do:

$.cookie("test", 1);

To delete:

$.removeCookie("test");

Additionally, to set a timeout of a certain number of days (10 here) on the cookie:

$.cookie("test", 1, { expires : 10 });

If the expires option is omitted, then the cookie becomes a session cookie and is deleted when the browser exits.

To cover all the options:

$.cookie("test", 1, {
   expires : 10,           // Expires in 10 days

   path    : '/',          // The value of the path attribute of the cookie
                           // (Default: path of page that created the cookie).

   domain  : 'jquery.com', // The value of the domain attribute of the cookie
                           // (Default: domain of page that created the cookie).

   secure  : true          // If set to true the secure attribute of the cookie
                           // will be set and the cookie transmission will
                           // require a secure protocol (defaults to false).
});

To read back the value of the cookie:

var cookieValue = $.cookie("test");

You may wish to specify the path parameter if the cookie was created on a different path to the current one:

var cookieValue = $.cookie("test", { path: '/foo' });

UPDATE (April 2015):

As stated in the comments below, the team that worked on the original plugin has removed the jQuery dependency in a new project (https://github.com/js-cookie/js-cookie) which has the same functionality and general syntax as the jQuery version. Apparently the original plugin isn't going anywhere though.

The easiest way is through keyword arguments:

class City():
  def __init__(self, city=None):
    pass

someCity = City(city="Berlin")

This is pretty basic stuff. Maybe look at the Python documentation?

$final_array = array_combine($a, $a);

Reference: http://php.net/array-combine

P.S. Be careful with source array containing duplicated keys like the following:

$a = ['one','two','one'];

Note the duplicated one element.

If you use docker-compose just set UPLOAD_LIMIT

phpmyadmin:
    image: phpmyadmin/phpmyadmin
    environment:
        UPLOAD_LIMIT: 1G

Use <> to negate the where clause.

Alt + Shift + o
Will solve your problem and agree with @Korhan Ozturk as well :)

This is known as Toggle Mark occurrence (Alt + Shift + O), Means will highlight all occurrence of focused variable. Same thing can be achieved from tool bar as follows

In same tool bar there is another switch if you turn that on you will see complete path for opened file, That is Breadcrumb

there are some more very useful switches like word wrap, Show white Characters just after toggle mark occurrence

There are differences and constraints in options offered by @Steve C and @ashosborne1. They must be specified, I believe.

When can we can use: File resourcesDirectory = new File("src/test/resources");?

• 1 When tests are going to be run via maven only but not via IDE.
• 2.1 When tests are going to be run via maven or
• 2.2 via IDE and only one project is imported into IDE. (I use “imported” term, cause it is used in IntelliJ IDEA. I think users of eclipse also import their maven project). This will work, cause working directory when you run tests via IDE is the same as your project.
• 3.1 When tests are going to be run via maven or
• 3.2 via IDE, and more than one projects are imported into IDE (when you are not a student, you usually import several projects), AND before you run tests via IDE, you manually configure working directory for your tests. That working directory should refer to your imported project that contains the tests. By default, working directory of all projects imported into IDE is only one. Probably it is a restriction of IntelliJ IDEA only, but I think all IDEs work like this. And this configuration that must be done manually, is not good at all. Working with several tests existing in different maven projects, but imported into one big “IDE” project, force us to remember this and don’t allow to relax and get pleasure from your work.

Solution offered by @ashosborne1 (personally I prefer this one) requires 2 additional requirements that must be done before you run tests. Here is a list of steps to use this solution:

• Create a test folder (“teva”) and file (“readme”) inside of “src/test/resources/”:

  src/test/resources/teva/readme

  File must be created in the test folder, otherwise, it will not work. Maven ignores empty folders.

• At least once build project via mvn clean install. It will run tests also. It may be enough to run only your test class/method via maven without building a whole project. As a result your test resources will be copied into test-classes, here is a path: target/test-classes/teva/readme

• After that, you can access the folder using code, already offered by @ashosborne1 (I'm sorry, that I could not edit this code inside of this list of items correctly):

public static final String TEVA_FOLDER = "teva"; ... 
URL tevaUrl = YourTest.class.getClassLoader().getResource(TEVA_FOLDER); 
String tevaTestFolder = new File(tevaUrl.toURI()).getAbsolutePath();

Now you can run your test via IDE as many times as you want. Until you run mvn clean. It will drop the target folder.

Creating file inside a test folder and running maven first time, before you run tests via IDE are needed steps. Without these steps, if you just in your IDE create test resources, then write test and run it via IDE only, you'll get an error. Running tests via mvn copies test resources into target/test-classes/teva/readme and they become accessible for a classloader.

You may ask, why do I need import more than one maven project in IDE and why so many complicated things? For me, one of the main motivation: keeping IDA-related files far from code. I first create a new project in my IDE. It is a fake project, that is just a holder of IDE-related files. Then, I import already existing maven projects. I force these imported projects to keep IDEA files in my original fake project only. As a result I don't see IDE-related files among the code. SVN should not see them (don't offer to configure svn/git to ignore such files, please). Also it is just very convenient.

Here is a "safe HTML" function using a 'reduce' multiple replacement function (this function applies each replacement to the entire string, so dependencies among replacements are significant).

// Test:
document.write(SafeHTML('<div>\n\
    x</div>'));

function SafeHTML(str)
    {
    const replacements = [
        {'&':'&amp;'},
        {'<':'&lt;'},
        {'>':'&gt;'},
        {'"':'&quot;'},
        {"'":'&apos;'},
        {'`':'&grave;'},
        {'\n':'<br>'},
        {' ':'&nbsp;'}
        ];
    return replaceManyStr(replacements,str);
    } // HTMLToSafeHTML

function replaceManyStr(replacements,str)
    {
    return replacements.reduce((accum,t) => accum.replace(new RegExp(Object.keys(t)[0],'g'),t[Object.keys(t)[0]]),str);
    }

You need the Microsoft.AspNet.WebApi.Core package.

You can see it in the .csproj file:

<Reference Include="System.Web.Http, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35, processorArchitecture=MSIL">
  <SpecificVersion>False</SpecificVersion>
  <HintPath>..\packages\Microsoft.AspNet.WebApi.Core.5.0.0\lib\net45\System.Web.Http.dll</HintPath>
</Reference>

I used SSH.Net in a project a while ago and was very happy with it. It also comes with a good documentation with lots of samples on how to use it.

The original package website can be still found here, including the documentation (which currently isn't available on GitHub).

For your case the code would be something like this.

using (var client = new SshClient("hostnameOrIp", "username", "password"))
{
    client.Connect();
    client.RunCommand("etc/init.d/networking restart");
    client.Disconnect();
}

In ksh you do it:

set -A array element1 element2 elementn

# view the first element
echo ${array[0]}

# Amount elements (You have to substitute 1)
echo ${#array[*]}

# show last element
echo ${array[ $(( ${#array[*]} - 1 )) ]}

If you wish to change the font color inside string.xml file, you may try the following code.

<resources>
   <string name="hello_world"><font fgcolor="#ffff0000">Hello world!</font></string>
</resources>

line=$((${RANDOM} % $(wc -l < /etc/passwd)))
sed -n "${line}p" /etc/passwd

just with your file instead.

In this example I used the file /etc/password, using the special variable ${RANDOM} (about which I learned here), and the sed expression you had, only difference is that I am using double quotes instead of single to allow the variable expansion.

I tried most of the recommended fixes here, and still couldn't avoid the error message. I finally performed a combination of a few recommended solutions:

1. Added this entry to the top of the AppSettings section of my web.config:

   <add key="owin:AutomaticAppStartup" value="false"/>

2. Expanded the References node of my project and deleted everything that contained the string OWIN. (I felt safe doing so since my organization is not (and won't be) an active OWIN provider in the future)

I then clicked Run and my homepage loaded right up.

Java doesn't allow you to do that. You'll need to refer to one of the classes by its fully qualified name and only import the other one.

This is where the window function row_number() comes in handy:

SELECT s.siteName, s.siteIP, h.date
FROM sites s INNER JOIN
     (select h.*, row_number() over (partition by siteName order by date desc) as seqnum
      from history h
     ) h
    ON s.siteName = h.siteName and seqnum = 1
ORDER BY s.siteName, h.date

I created it a long time ago, related question

String.Format = function (b) {
    var a = arguments;
    return b.replace(/(\{\{\d\}\}|\{\d\})/g, function (b) {
        if (b.substring(0, 2) == "{{") return b;
        var c = parseInt(b.match(/\d/)[0]);
        return a[c + 1]
    })
};

If you want to do this in RegexBuddy, there are two ways to get a list of all lines not matching a regex.

On the toolbar on the Test panel, set the test scope to "Line by line". When you do that, an item List All Lines without Matches will appear under the List All button on the same toolbar. (If you don't see the List All button, click the Match button in the main toolbar.)

On the GREP panel, you can turn on the "line-based" and the "invert results" checkboxes to get a list of non-matching lines in the files you're grepping through.

In my case, when I'm in an activity that extends from AppCompatActivity, it did not work(Activity) getApplicationContext (), I just putthis in its place.

>>> x = 'lipsum'
>>> x.replace(x[:3], '')
'sum'

Give this a try:

PS> $nl = [Environment]::NewLine
PS> gci hklm:\software\microsoft\windows\currentversion\uninstall | 
        ForEach { $_.GetValue("DisplayName") } | Where {$_} | Sort |
        Foreach {"$_$nl"} | Out-File addrem.txt -Enc ascii

It yields the following text in my addrem.txt file:

Adobe AIR

Adobe Flash Player 10 ActiveX

...

Note: on my system, GetValue("DisplayName") returns null for some entries, so I filter those out. BTW, you were close with this:

ForEach-Object -Process { "$_.GetValue("DisplayName") `n" }

Except that within a string, if you need to access a property of a variable, that is, "evaluate an expression", then you need to use subexpression syntax like so:

Foreach-Object -Process { "$($_.GetValue('DisplayName'))`r`n" }

Essentially within a double quoted string PowerShell will expand variables like $_, but it won't evaluate expressions unless you put the expression within a subexpression using this syntax:

$(`<Multiple statements can go in here`>).

Seems like you can't iterate through JSONArray with a for each. You can loop through your JSONArray like this:

for (int i=0; i < arr.length(); i++) {
    arr.getJSONObject(i);
}

You can use ymd from lubridate

lubridate::ymd(v)
#[1] "2008-11-01"

Or anytime::anydate

anytime::anydate(v)
#[1] "2008-11-01"

Mostly the image is not displayed because you URL contains spaces. In your case you almost did everything correct. Except one thing - you have not added single quotes like you do if you specify background-image in css I.e.

.bg-img {                \/          \/
    background-image: url('http://...');
}

To do so escape quot character in HTML via \'

                                          \/                                  \/
<div [ngStyle]="{'background-image': 'url(\''+ item.color.catalogImageLink + '\')'}"></div>

I think that main difference is whether you frequently need to insert or remove stuff from the top of the list.

With an array, if you remove something from the top of list than the complexity is o(n) because all of the indices of the array elements will have to shift.

With a linked list, it is o(1) because you need only create the node, reassign the head and assign the reference to next as the previous head.

When frequently inserting or removing at the end of the list, arrays are preferable because the complexity will be o(1), no reindexing is required, but for a linked list it will be o(n) because you need to go from the head to the last node.

I think that searching in both linked list and arrays will be o(log n) because you will be probably be using a binary search.

I think the correct access method is using the index:

df_2.loc[:,'D'] = df_2['B']

Since this issue happened because calling model another time. Work around to this issue by wrapping your model code in try catch block. typescript code is like this -

         Import {Schema, model} from 'mongoose';
         export function user(){
              try{
                   return model('user', new Schema ({
                            FirstName: String,
                            Last name: String
                     }));
              }
             catch{
                   return model('user');
              }
         }

Similarly you can write code in js too.

Simply type the command:

$ gdb <Binary> <codeDump>

Or

$ gdb <binary>

$ gdb) core <coreDump>

There isn't any need to provide any command line argument. The code dump generated due to an earlier exercise.

To answer the updated part of your question: to style the drawer icon/arrow, you have two options:

Style the arrow itself

To do this, override drawerArrowStyle in your theme like so:

<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <item name="drawerArrowStyle">@style/MyTheme.DrawerArrowToggle</item>
</style>
<style name="MyTheme.DrawerArrowToggle" parent="Widget.AppCompat.DrawerArrowToggle">
    <item name="color">@android:color/holo_purple</item>
    <!-- ^ this will make the icon purple -->
</style>

This is probably not what you want, because the ActionBar itself should have consistent styling with the arrow, so, most probably, you want the option two:

Theme the ActionBar/Toolbar

Override the android:actionBarTheme (actionBarTheme for appcompat) attribute of the global application theme with your own theme (which you probably should derive from ThemeOverlay.Material.ActionBar/ThemeOverlay.AppCompat.ActionBar) like so:

<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <item name="actionBarTheme">@style/MyTheme.ActionBar</item>
</style>
<style name="MyTheme.ActionBar" parent="ThemeOverlay.AppCompat.ActionBar">
    <item name="android:textColorPrimary">@android:color/white</item>
    <!-- ^ this will make text and arrow white -->
    <!-- you can also override drawerArrowStyle here -->
</style>

An important note here is that when using a custom layout with a Toolbar instead of stock ActionBar implementation (e.g. if you're using the DrawerLayout-NavigationView-Toolbar combo to achieve the Material-style drawer effect where it's visible under translucent statusbar), the actionBarTheme attribute is obviosly not picked up automatically (because it's meant to be taken care of by the AppCompatActivity for the default ActionBar), so for your custom Toolbar don't forget to apply your theme manually:

<!--inside your custom layout with DrawerLayout
and NavigationView or whatever -->
<android.support.v7.widget.Toolbar
        ...
        app:theme="?actionBarTheme">

-- this will resolve to either AppCompat's default ThemeOverlay.AppCompat.ActionBar or your override if you set the attribute in your derived theme.

PS a little comment about the drawerArrowStyle override and the spinBars attribute -- which a lot of sources suggest should be set to true to get the drawer/arrow animation. Thing is, spinBars it is true by default in AppCompat (check out the Base.Widget.AppCompat.DrawerArrowToggle.Common style), you don't have to override actionBarTheme at all to get the animation working. You get the animation even if you do override it and set the attribute to false, it's just a different, less twirly animation. The important thing here is to use ActionBarDrawerToggle, it's what pulls in the fancy animated drawable.

I use the following snippet to view all the rows in a table. Use a query to find all the rows. The returned objects are the class instances. They can be used to view/edit the values as required:

from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import create_engine, Sequence
from sqlalchemy import String, Integer, Float, Boolean, Column
from sqlalchemy.orm import sessionmaker

Base = declarative_base()

class MyTable(Base):
    __tablename__ = 'MyTable'
    id = Column(Integer, Sequence('user_id_seq'), primary_key=True)
    some_col = Column(String(500))

    def __init__(self, some_col):
        self.some_col = some_col

engine = create_engine('sqlite:///sqllight.db', echo=True)
Session = sessionmaker(bind=engine)
session = Session()

for class_instance in session.query(MyTable).all():
    print(vars(class_instance))

session.close()

You CAN use UTF-8 in the POST request, all you need is to specify the charset in your request.

You should use this request:

curl -X POST -H "Content-Type: application/x-www-form-urlencoded; charset=utf-8" --data-ascii "content=derinhält&date=asdf" http://myserverurl.com/api/v1/somemethod

The easiest way would be to specify

SELECT productid FROM product where purchase_date > sysdate-30;

Remember this sysdate above has the time component, so it will be purchase orders newer than 03-06-2011 8:54 AM based on the time now.

If you want to remove the time conponent when comparing..

SELECT productid FROM product where purchase_date > trunc(sysdate-30);

And (based on your comments), if you want to specify a particular date, make sure you use to_date and not rely on the default session parameters.

SELECT productid FROM product where purchase_date > to_date('03/06/2011','mm/dd/yyyy')

And regardng the between (sysdate-30) - (sysdate) comment, for orders you should be ok with usin just the sysdate condition unless you can have orders with order_dates in the future.

Just use public_path() it will find public folder and address it itself.

<img src=public_path().'/images/imagename.jpg' >

Give this a shot:

SELECT name, description, ...
WHERE id IN
    (SELECT id FROM table1 WHERE...)
ORDER BY
    (SELECT display_order FROM table1 WHERE...),
    (SELECT name FROM table1 WHERE...)

The WHEREs will probably take a little tweaking to get the correlated subqueries working properly, but the basic principle should be sound.

If you want to remove all pending tasks and also the active and reserved ones to completely stop Celery, this is what worked for me:

from proj.celery import app
from celery.task.control import inspect, revoke

# remove pending tasks
app.control.purge()

# remove active tasks
i = inspect()
jobs = i.active()
for hostname in jobs:
    tasks = jobs[hostname]
    for task in tasks:
        revoke(task['id'], terminate=True)

# remove reserved tasks
jobs = i.reserved()
for hostname in jobs:
    tasks = jobs[hostname]
    for task in tasks:
        revoke(task['id'], terminate=True)

How about creating your own Custom Panel class? That way you won't have to worry about overriding Bootstrap.

HTML

<div class="panel panel-custom-horrible-red">
   <div class="panel-heading">
      <h3 class="panel-title">Panel title</h3>
   </div>
   <div class="panel-body">
      Panel content
    </div>
</div>

CSS

.panel-custom-horrible-red {
    border-color: #ff0000;
}
.panel-custom-horrible-red > .panel-heading {
    background: #ff0000; 
    color: #ffffff;
    border-color: #ff0000;
}

So from the error above. All you have to do to fix this issue is to revert your code. (git revert HEAD) then git pull and then redo your changes, then git pull again and was able to commit or merge with no errors.

In Bash and zsh you can do this with Brace Expansion. This simply expands a list of items in braces. For example:

# echo {vanilla,chocolate,strawberry}-ice-cream
vanilla-ice-cream chocolate-ice-cream strawberry-ice-cream

So you can do your rename as follows:

mv {,new.}original.filename

as this expands to:

mv original.filename new.original.filename

I find that image mapping works pretty well. If you have any headers or footers that are images make sure that you apply a bgcolor="fill in the blank" because outlook in most cases wont load the image and you will be left with a transparent header. If you at least designate a color that works with the over all feel of the email it will be less of a shock for the user. Never try and use any styling sheets. Or CSS at all! Just avoid it.

Depending if you're copying content from a word or shared google Doc be sure to (command+F) Find all the (') and (") and replace them within your editing software (especially dreemweaver) because they will show up as code and it's just not good.

ALT is your best friend. use the ALT tag to add in text to all your images. Because odds are they are not going to load right. And that ALT text is what gets people to click the (see images) button. Also define your images Width, Height and make the boarder 0 so you dont get weird lines around your image.

Consider editing all images within Photoshop with a 15px boarder on each side (make background transparent and save as a PNG 24) of image. Sometimes the email clients do not read any padding styles that you apply to the images so it avoids any weird formatting!

Also i found the line under links particularly annoying so if you apply < style="text-decoration:none; color:#whatever color you want here!" > it will remove the line and give you the desired look.

There is alot that can really mess with the over all look and feel.

Regret to say, but Both Otacku's and @clatonh's methods aren't working for me - neither have Outlook Bitness nor {90140000-0011-0000-1000-0000000FF1CE} in registry (for 64-bit Office without Outlook installed).

The only way I have found, though, not via the registry, is to check bitness for one of the Office executables with the use of the Windows API function GetBinaryType (since Windows 2000 Professional).

For example, you can check the bitness of Winword.exe, which path is stored under
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\Winword.exe.

Here is the MFC code fragment:

CRegKey rk;
if (ERROR_SUCCESS == rk.Open(HKEY_LOCAL_MACHINE, 
  "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\App Paths\\Winword.exe", 
  KEY_READ)) {
    CString strWinwordPath;
    DWORD dwSize = MAX_PATH;
    if (ERROR_SUCCESS == rk.QueryStringValue(strWinwordPath, 
        strWinwordPath.GetBuffer(MAX_PATH), &dwSize)) {
            strWinwordPath.ReleaseBuffer();
            DWORD dwBinaryType;
            if (::GetBinaryType(strWinwordPath, &dwBinaryType)) {
                if (SCS_64BIT_BINARY == dwBinaryType) {
                    // Detected 64-bit Office 
                } else {
                    // Detected 32-bit Office 
                }
            } else {
                // Failed
            }
        } else {
            // Failed
        }
    } else {
    // Failed
}

Just had a similar issue

Resolved it by checking in httpd.conf

     # AllowOverride controls what directives may be placed in .htaccess files.
     # It can be "All", "None", or any combination of the keywords:
     #   Options FileInfo AuthConfig Limit
     #
     AllowOverride All   <--- make sure this is not set to "None"

It is worth bearing in mind I tried (from Mark's answer) the "put garbage in the .htaccess" which did give a server error - but even though it was being read, it wasn't being acted on due to no overrides allowed.

Just to show an example of how to dynamically add the "Content-type" header to every POST request. In may case I'm passing POST params as query string, that is done using the transformRequest. In this case its value is application/x-www-form-urlencoded.

// set Content-Type for POST requests
angular.module('myApp').run(basicAuth);
function basicAuth($http) {
    $http.defaults.headers.post = {'Content-Type': 'application/x-www-form-urlencoded'};
}

Then from the interceptor in the request method before return the config object

// if header['Content-type'] is a POST then add data
'request': function (config) {
  if (
    angular.isDefined(config.headers['Content-Type']) 
    && !angular.isDefined(config.data)
  ) {
    config.data = '';
  }
  return config;
}

Packet Capture Android app implements a VPN that logs all network traffic on the Android device. You don't need to setup any VPN/proxy server on your PC. Does not needs root. Supports SSL decryption which tPacketCapture does not. It also includes a good log viewer.

I would suggest adding

(?!.*pass|.*word|.*1234|.*qwer|.*asdf) exclude common passwords

You can't use add_timestamps and null:false if you have existing records, so here is the solution :

def change
  add_timestamps(:buttons, null: true)

  Button.find_each { |b| b.update(created_at: Time.zone.now, updated_at: Time.zone.now) }

  change_column_null(:buttons, :created_at, false)
  change_column_null(:buttons, :updated_at, false)
end

I frequently use this because it's short and provides the syntactic sugar I need...

public class MultiKeyDictionary<T1, T2, T3> : Dictionary<T1, Dictionary<T2, T3>>
{
    new public Dictionary<T2, T3> this[T1 key]
    {
        get
        {
            if (!ContainsKey(key))
                Add(key, new Dictionary<T2, T3>());

            Dictionary<T2, T3> returnObj;
            TryGetValue(key, out returnObj);

            return returnObj;
        }
    }
}

To use it:

dict[cat][fish] = 9000;

where the "Cat" key doesn't have to exist either.

There are tcpdump filters for HTTP GET & HTTP POST (or for both plus message body):

• Run man tcpdump | less -Ip examples to see some examples

• Here’s a tcpdump filter for HTTP GET (GET = 0x47, 0x45, 0x54, 0x20):

  sudo tcpdump -s 0 -A 'tcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x47455420'
  

• Here’s a tcpdump filter for HTTP POST (POST = 0x50, 0x4f, 0x53, 0x54):

  sudo tcpdump -s 0 -A 'tcp dst port 80 and (tcp[((tcp[12:1] & 0xf0) >> 2):4] = 0x504f5354)'
  

• Monitor HTTP traffic including request and response headers and message body (source):

  tcpdump -A -s 0 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)'
  tcpdump -X -s 0 'tcp port 80 and (((ip[2:2] - ((ip[0]&0xf)<<2)) - ((tcp[12]&0xf0)>>2)) != 0)'
  

For more information on the bit-twiddling in the TCP header see: String-Matching Capture Filter Generator (link to Sake Blok's explanation).

Do you mean you want the script's own path so you can reference a file next to the script? Try this:

$scriptpath = $MyInvocation.MyCommand.Path
$dir = Split-Path $scriptpath
Write-host "My directory is $dir"

You can get a lot of info from $MyInvocation and its properties.

If you want to reference a file in the current working directory, you can use Resolve-Path or Get-ChildItem:

$filepath = Resolve-Path "somefile.txt"

EDIT (based on comment from OP):

# temporarily change to the correct folder
Push-Location $folder

# do stuff, call ant, etc

# now back to previous directory
Pop-Location

There's probably other ways of achieving something similar using Invoke-Command as well.

I usually lose track of all of my -20001-type error codes, so I try to consolidate all my application errors into a nice package like such:

SET SERVEROUTPUT ON

CREATE OR REPLACE PACKAGE errors AS
  invalid_foo_err EXCEPTION;
  invalid_foo_num NUMBER := -20123;
  invalid_foo_msg VARCHAR2(32767) := 'Invalid Foo!';
  PRAGMA EXCEPTION_INIT(invalid_foo_err, -20123);  -- can't use var >:O

  illegal_bar_err EXCEPTION;
  illegal_bar_num NUMBER := -20156;
  illegal_bar_msg VARCHAR2(32767) := 'Illegal Bar!';
  PRAGMA EXCEPTION_INIT(illegal_bar_err, -20156);  -- can't use var >:O

  PROCEDURE raise_err(p_err NUMBER, p_msg VARCHAR2 DEFAULT NULL);
END;
/

CREATE OR REPLACE PACKAGE BODY errors AS
  unknown_err EXCEPTION;
  unknown_num NUMBER := -20001;
  unknown_msg VARCHAR2(32767) := 'Unknown Error Specified!';

  PROCEDURE raise_err(p_err NUMBER, p_msg VARCHAR2 DEFAULT NULL) AS
    v_msg VARCHAR2(32767);
  BEGIN
    IF p_err = unknown_num THEN
      v_msg := unknown_msg;
    ELSIF p_err = invalid_foo_num THEN
      v_msg := invalid_foo_msg;
    ELSIF p_err = illegal_bar_num THEN
      v_msg := illegal_bar_msg;
    ELSE
      raise_err(unknown_num, 'USR' || p_err || ': ' || p_msg);
    END IF;

    IF p_msg IS NOT NULL THEN
      v_msg := v_msg || ' - '||p_msg;
    END IF;

    RAISE_APPLICATION_ERROR(p_err, v_msg);
  END;
END;
/

Then call errors.raise_err(errors.invalid_foo_num, 'optional extra text') to use it, like such:

BEGIN
  BEGIN
    errors.raise_err(errors.invalid_foo_num, 'Insufficient Foo-age!');
  EXCEPTION
    WHEN errors.invalid_foo_err THEN
      dbms_output.put_line(SQLERRM);
  END;

  BEGIN
    errors.raise_err(errors.illegal_bar_num, 'Insufficient Bar-age!');
  EXCEPTION
    WHEN errors.illegal_bar_err THEN
      dbms_output.put_line(SQLERRM);
  END;

  BEGIN
    errors.raise_err(-10000, 'This Doesn''t Exist!!');
  EXCEPTION
    WHEN OTHERS THEN
      dbms_output.put_line(SQLERRM);
  END;
END;
/

produces this output:

ORA-20123: Invalid Foo! - Insufficient Foo-age!
ORA-20156: Illegal Bar! - Insufficient Bar-age!
ORA-20001: Unknown Error Specified! - USR-10000: This Doesn't Exist!!

Try this:

$('#contra').focusout(function (){
    $('#btnPassword').focus();
});

Another option is the static String.valueOf method.

String.valueOf(i)

It feels slightly more right than Integer.toString(i) to me. When the type of i changes, for example from int to double, the code will stay correct.

Method 1 (Preferred) - Using hMailServer

After installation, you need the following configuration to properly send mail from wampserver:

1) When you first open hMailServer Administrator, you need to add a new domain.
2) Click on the "Add Domain ..." button at the Welcome page. 
3) Under the domain text field, enter your computer's IP, in this case it should be 127.0.0.1.
4) Click on the Save button.
5) Go to Settings>Protocols>SMTP and select "Delivery of Email" tab
6) Enter "localhost" in the localhost name field.
7) Click on the Save button.

If you need to send mail using a FROM addressee of another computer, you need to allow deliveries from External to External accounts. To do that, follow these steps:

1) Go to Settings>Advanced>IP Ranges and double click on "My Computer" which should have IP address of 127.0.0.1
2) Check the Allow Deliveries from External to External accounts checkbox.
3) Save settings using Save button.

(However, Windows Live/Hotmail has denied all emails coming from dynamic IPs, which most residential computers are using. The workaround is to use Gmail account )

Note to use Gmail users :

1) Go to Settings>Protocols>SMTP and select "Delivery of Email" tab
2) Enter "smtp.gmail.com" in the Remote Host name field.
3) Enter "465" as the port number
4) Check "Server requires authentication"
5) Enter gmail address in the Username
6) Enter gmail password in the password 
7) Check "Use SSL"

(Note, From field doesnt function with gmail)
*p.s. For some people it might also be needed to untick everything under require SMTP authentication in :

• for local : Settings>Advanced>IP Ranges>"My Computer"
  
• for external : Settings>Advanced>IP Ranges>"Internet"

Method 2 - Using SendMail

You can use SendMail installation.

Method 3 - Using different methods

Use any of these methods.

As stated in many other answers both methods perform shallow copies of the array. However there are differences and recommendations that have not been addressed yet and that are highlighted in the following lists.

Characteristics of System.Array.Clone:

• Tests, using .NET 4.0, show that it is slower than CopyTo probably because it uses Object.MemberwiseClone;
• Requires casting the result to the appropriate type;
• The resulting array has the same length as the source.

Characteristics of System.Array.CopyTo:

• Is faster than Clone when copying to array of same type;
• It calls into Array.Copy inheriting is capabilities, being the most useful ones:
  • Can box value type elements into reference type elements, for example, copying an int[] array into an object[];
  • Can unbox reference type elements into value type elements, for example, copying a object[] array of boxed int into an int[];
  • Can perform widening conversions on value types, for example, copying a int[] into a long[].
  • Can downcast elements, for example, copying a Stream[] array into a MemoryStream[] (if any element in source array is not convertible to MemoryStream an exception is thrown).
• Allows to copy the source to a target array that has a length greater than the source.

Also note, these methods are made available to support ICloneable and ICollection, so if you are dealing with variables of array types you should not use Clone or CopyTo and instead use Array.Copy or Array.ConstrainedCopy. The constrained copy assures that if the copy operation cannot complete successful then the target array state is not corrupted.

Try this:

div {
    width: 200px;
    word-wrap: break-word;
}

Put a black, semitransparent, div on top of it.

Here is the official explanation: https://github.com/golang/go/wiki/InterfaceSlice

var dataSlice []int = foo()
var interfaceSlice []interface{} = make([]interface{}, len(dataSlice))
for i, d := range dataSlice {
    interfaceSlice[i] = d
}

This is how to load/use a local html with relative references.

1. Drag the resource into your xcode project (I dragged a folder named www from my finder window), you will get two options "create groups for any added folders" and "create folders references for any added folders".
2. Select the "create folder references.." option.

3. Use the below given code. It should work like a charm.

   NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"index" ofType:@"html" inDirectory:@"www"]];
[webview loadRequest:[NSURLRequest requestWithURL:url]];

Now all your relative links(like img/.gif, js/.js) in the html should get resolved.

Swift 3

    if let path = Bundle.main.path(forResource: "dados", ofType: "html", inDirectory: "root") {
        webView.load( URLRequest(url: URL(fileURLWithPath: path)) )
    }

If you are making your own module then add CommonModule in imports in your own module

You can convert, but I don't think there's anything built in to do it automatically:

public static int[] convertIntegers(List<Integer> integers)
{
    int[] ret = new int[integers.size()];
    for (int i=0; i < ret.length; i++)
    {
        ret[i] = integers.get(i).intValue();
    }
    return ret;
}

(Note that this will throw a NullPointerException if either integers or any element within it is null.)

EDIT: As per comments, you may want to use the list iterator to avoid nasty costs with lists such as LinkedList:

public static int[] convertIntegers(List<Integer> integers)
{
    int[] ret = new int[integers.size()];
    Iterator<Integer> iterator = integers.iterator();
    for (int i = 0; i < ret.length; i++)
    {
        ret[i] = iterator.next().intValue();
    }
    return ret;
}

if (($("#one").length > 0)){
   alert('yes');
}

if (($("#two").length > 0)){
   alert('yes');
}

if (($("#three").length > 0)){
   alert('yes');
}

if (($("#four")).length == 0){
   alert('no');
}

This is what you need :)

Base on @tbranyen's solution, I create an index.js file that load arbitrary javascripts under current folder as part of the exports.

// Load `*.js` under current directory as properties
//  i.e., `User.js` will become `exports['User']` or `exports.User`
require('fs').readdirSync(__dirname + '/').forEach(function(file) {
  if (file.match(/\.js$/) !== null && file !== 'index.js') {
    var name = file.replace('.js', '');
    exports[name] = require('./' + file);
  }
});

Then you can require this directory from any where else.

Why does it implement its methods? How can it implement its methods when an interface can't contain method body? How can it implement the methods when it extends the other interface and not implement it? What is the purpose of an interface implementing another interface?

Interface does not implement the methods of another interface but just extends them. One example where the interface extension is needed is: consider that you have a vehicle interface with two methods moveForward and moveBack but also you need to incorporate the Aircraft which is a vehicle but with some addition methods like moveUp, moveDown so in the end you have:

public interface IVehicle {
  bool moveForward(int x);
  bool moveBack(int x);
};

and airplane:

public interface IAirplane extends IVehicle {
  bool moveDown(int x);
  bool moveUp(int x);
};

Use Notification Center in the viewDidLoad: method of your ViewController to call a method and from there do what you were supposed to do in your viewWillAppear: method. Calling viewWillAppear: directly is not a good option.

- (void)viewDidLoad
{
    [super viewDidLoad];
    NSLog(@"view did load");

    [[NSNotificationCenter defaultCenter] addObserver:self 
        selector:@selector(applicationIsActive:) 
        name:UIApplicationDidBecomeActiveNotification 
        object:nil];

    [[NSNotificationCenter defaultCenter] addObserver:self 
        selector:@selector(applicationEnteredForeground:) 
        name:UIApplicationWillEnterForegroundNotification
        object:nil];
}

- (void)applicationIsActive:(NSNotification *)notification {
    NSLog(@"Application Did Become Active");
}

- (void)applicationEnteredForeground:(NSNotification *)notification {
    NSLog(@"Application Entered Foreground");
}

Regarding @Suragch's Alternative to "Remove element of unknown index":

There is a more powerful version of "indexOf(element)" that will match on a predicate instead of the object itself. It goes by the same name but it called by myObjects.indexOf{$0.property = valueToMatch}. It returns the index of the first matching item found in myObjects array.

If the element is an object/struct, you may want to remove that element based on a value of one of its properties. Eg, you have a Car class having car.color property, and you want to remove the "red" car from your carsArray.

if let validIndex = (carsArray.indexOf{$0.color == UIColor.redColor()}) {
  carsArray.removeAtIndex(validIndex)
}

Foreseeably, you could rework this to remove "all" red cars by embedding the above if statement within a repeat/while loop, and attaching an else block to set a flag to "break" out of the loop.

name = "my text"
x.times do name.chop! end

Here in the console:

>name = "Nabucodonosor"
 => "Nabucodonosor" 
> 7.times do name.chop! end
 => 7 
> name
 => "Nabuco" 

Tuples are compared position by position: the first item of the first tuple is compared to the first item of the second tuple; if they are not equal (i.e. the first is greater or smaller than the second) then that's the result of the comparison, else the second item is considered, then the third and so on.

See Common Sequence Operations:

Sequences of the same type also support comparisons. In particular, tuples and lists are compared lexicographically by comparing corresponding elements. This means that to compare equal, every element must compare equal and the two sequences must be of the same type and have the same length.

Also Value Comparisons for further details:

Lexicographical comparison between built-in collections works as follows:

• For two collections to compare equal, they must be of the same type, have the same length, and each pair of corresponding elements must compare equal (for example, [1,2] == (1,2) is false because the type is not the same).
• Collections that support order comparison are ordered the same as their first unequal elements (for example, [1,2,x] <= [1,2,y] has the same value as x <= y). If a corresponding element does not exist, the shorter collection is ordered first (for example, [1,2] < [1,2,3] is true).

If not equal, the sequences are ordered the same as their first differing elements. For example, cmp([1,2,x], [1,2,y]) returns the same as cmp(x,y). If the corresponding element does not exist, the shorter sequence is considered smaller (for example, [1,2] < [1,2,3] returns True).

Note 1: < and > do not mean "smaller than" and "greater than" but "is before" and "is after": so (0, 1) "is before" (1, 0).

Note 2: tuples must not be considered as vectors in a n-dimensional space, compared according to their length.

Note 3: referring to question https://stackoverflow.com/questions/36911617/python-2-tuple-comparison: do not think that a tuple is "greater" than another only if any element of the first is greater than the corresponding one in the second.

Or the Euclidean algorithm for calculating the GCD...

public int egcd(int a, int b) {
    if (a == 0)
        return b;

    while (b != 0) {
        if (a > b)
            a = a - b;
        else
            b = b - a;
    }

    return a;
}

The svg-tag needs the namespace attribute xmlns:

<svg xmlns="http://www.w3.org/2000/svg"></svg>

If you need to update the value in a particular table:

UPDATE TABLE-NAME SET COLUMN-NAME = REPLACE(TABLE-NAME.COLUMN-NAME, 'STRING-TO-REPLACE', 'REPLACEMENT-STRING');

where

  TABLE-NAME         - The name of the table being updated
  COLUMN-NAME        - The name of the column being updated
  STRING-TO-REPLACE  - The value to replace
  REPLACEMENT-STRING - The replacement

You are simply sending signals to the processes. kill is a command to send those signals.

The keyboard command Ctrl+C sends a SIGINT, kill -9 sends a SIGKILL, and kill -15 sends a SIGTERM.

What signal do you want to send to your server to end it?

I had the same problem and resulted that was an "every day" error in the rails controller. I don't know why, but on production, puma runs the error again and again causing the message:

upstream timed out (110: Connection timed out) while reading response header from upstream

Probably because Nginx tries to get the data from puma again and again.The funny thing is that the error caused the timeout message even if I'm calling a different action in the controller, so, a single typo blocks all the app.

Check your log/puma.stderr.log file to see if that is the situation.

You can always load a json data

here i defined Chart as namespace

 $.getJSON('data.json', function(data){
                Chart.options.series[0].data = data[0].data;
                Chart.options.series[1].data = data[1].data;
                Chart.options.series[2].data = data[2].data;

                var chart = new Highcharts.Chart(Chart.options);

            });

You don't need jQuery to create a Script DOM Element. It can be done with vanilla ES6 like so:

const script = "console.log('Did it work?')"
new Promise((resolve, reject) => {
  (function(i,s,o,g,r,a,m){
      a=s.createElement(o),m=s.getElementsByTagName(o)[0];
      a.innerText=g;
      a.onload=r;m.parentNode.insertBefore(a,m)}
  )(window,document,'script',script, resolve())
}).then(() => console.log('Sure did!'))

It doesn't need to be wrapped in a Promise, but doing so allows you to resolve the promise when the script loads, helping prevent race conditions for long-running scripts.

compiler changes checks your source code for errors and changes it into object code.this is the code that operating system runs.

You often don't write a whole program in single file so linker links all your object code files.

your program wont get executed unless it is in main memory

Use newtonsoft like so:

using System.Collections.Generic;
using System.Linq;
using Newtonsoft.Json.Linq;

class Program
{
    static void Main()
    {
        string json = "{'results':[{'SwiftCode':'','City':'','BankName':'Deutsche    Bank','Bankkey':'10020030','Bankcountry':'DE'},{'SwiftCode':'','City':'10891    Berlin','BankName':'Commerzbank Berlin (West)','Bankkey':'10040000','Bankcountry':'DE'}]}";

        var resultObjects = AllChildren(JObject.Parse(json))
            .First(c => c.Type == JTokenType.Array && c.Path.Contains("results"))
            .Children<JObject>();

        foreach (JObject result in resultObjects) {
            foreach (JProperty property in result.Properties()) {
                // do something with the property belonging to result
            }
        }
    }

    // recursively yield all children of json
    private static IEnumerable<JToken> AllChildren(JToken json)
    {
        foreach (var c in json.Children()) {
            yield return c;
            foreach (var cc in AllChildren(c)) {
                yield return cc;
            }
        }
    }
}

You can change this in your CSS with the property padding:

.navbar-nav > li{
  padding-left:30px;
  padding-right:30px;
}

Also you can set margin

.navbar-nav > li{
  margin-left:30px;
  margin-right:30px;
}

Try this. Don't forget using System.Reflection.

string baseDir = System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location);

sp_help will give you a whole bunch of information about a table including the columns, keys and constraints. For example, running

exec sp_help 'Address' 

will give you information about Address.

I think that for simple HTTP requests like this it's better to use the request module. You need to install it with npm (npm install request) and then your code can look like this:

const request = require('request')
     ,url = 'http://graph.facebook.com/517267866/?fields=picture'

request(url, (error, response, body)=> {
  if (!error && response.statusCode === 200) {
    const fbResponse = JSON.parse(body)
    console.log("Got a response: ", fbResponse.picture)
  } else {
    console.log("Got an error: ", error, ", status code: ", response.statusCode)
  }
})

This happened to me, even though I had already registered the Bundle Id with my account. It turns out that the capitalisation differed, so I had to change the bundle id in Xcode to lowercase, and it all worked. Hope that helps someone else :)

Combining a couple of the previous answers, you could try start /b cmd /c foo.exe.

For a trivial example, if you wanted to print out the versions of java/groovy/grails/gradle, you could do this in a batch file:

@start /b cmd /c java -version
@start /b cmd /c gradle -version
@start /b cmd /c groovy -version
@start /b cmd /c grails -version

If you have something like Process Explorer (Sysinternals), you will see a few child cmd.exe processes each with a java process (as per the above commands). The output will print to the screen in whatever order they finish.

start /b :  Start application without creating a new window. The
             application has ^C handling ignored. Unless the application
             enables ^C processing, ^Break is the only way to interrupt
             the application

cmd /c : Carries out the command specified by string and then terminates

It is very simple and above answers are complicating things. Simply you can get both local and public ip addresses using this method.

   <?php 
$publicIP = file_get_contents("http://ipecho.net/plain");
echo $publicIP;

$localIp = gethostbyname(gethostname());
echo $localIp;

?>

Try

string reversed(temp.rbegin(), temp.rend());

EDIT: Elaborating as requested.

string::rbegin() and string::rend(), which stand for "reverse begin" and "reverse end" respectively, return reverse iterators into the string. These are objects supporting the standard iterator interface (operator* to dereference to an element, i.e. a character of the string, and operator++ to advance to the "next" element), such that rbegin() points to the last character of the string, rend() points to the first one, and advancing the iterator moves it to the previous character (this is what makes it a reverse iterator).

Finally, the constructor we are passing these iterators into is a string constructor of the form:

template <typename Iterator>
string(Iterator first, Iterator last);

which accepts a pair of iterators of any type denoting a range of characters, and initializes the string to that range of characters.

The input operator for number skips leading whitespace, so you can just read the number in a loop:

while (myfile >> a)
{
    // ...
}

I've wrapped Darin's answer into a nicely reusable extension method.

This past week I installed Microsoft SQL Server 2014 Developer Edition on my dev box, and immediately ran into a problem I had never seen before.

I’ve installed various versions of SQL Server countless times, and it is usually a painless procedure. Install the server, run the Management Console, it’s that simple. However, after completing this installation, when I tried to log in to the server using SSMS, I got an error like the one below:

SQL Server login error 18456 “Login failed for user… (Microsoft SQL Server, Error: 18456)” I’m used to seeing this error if I typed the wrong password when logging in – but that’s only if I’m using mixed mode (Windows and SQL Authentication). In this case, the server was set up with Windows Authentication only, and the user account was my own. I’m still not sure why it didn’t add my user to the SYSADMIN role during setup; perhaps I missed a step and forgot to add it. At any rate, not all hope was lost.

The way to fix this, if you cannot log on with any other account to SQL Server, is to add your network login through a command line interface. For this to work, you need to be an Administrator on Windows for the PC that you’re logged onto.

Stop the MSSQL service. Open a Command Prompt using Run As Administrator. Change to the folder that holds the SQL Server EXE file; the default for SQL Server 2014 is “C:\Program Files\Microsoft SQL Server\MSSQL12.MSSQLSERVER\MSSQL\Binn”. Run the following command: “sqlservr.exe –m”. This will start SQL Server in single-user mode. While leaving this Command Prompt open, open another one, repeating steps 2 and 3. In the second Command Prompt window, run “SQLCMD –S Server_Name\Instance_Name” In this window, run the following lines, pressing Enter after each one: 1

CREATE LOGIN [domainName\loginName] FROM WINDOWS 2 GO 3 SP_ADDSRVROLEMEMBER 'LOGIN_NAME','SYSADMIN' 4 GO Use CTRL+C to end both processes in the Command Prompt windows; you will be prompted to press Y to end the SQL Server process.

Restart the MSSQL service. That’s it! You should now be able to log in using your network login.

In short, to do modification on the list while iterating the same list.

list[:] = ["Modify the list" for each_element in list "Condition Check"]

example:

list[:] = [list.remove(each_element) for each_element in list if each_element in ["data1", "data2"]]

you could also create a class which extends ArrayList:

public static class MyList extends ArrayList<Myclass> {}

and then use it like:

List<MyClass> list = objectMapper.readValue(json, MyList.class);

Give the path relative to your project.

Create a folder called resources in your src and put your config file there.

   configuration.configure("/resources/hibernate.cfg.xml");

And If you check your code

Configuration  configuration = new Configuration().configure( "C:\\Users\\Nikolay_Tkachev\\workspace\\hiberTest\\src\\logic\\hibernate.cfg.xml");
return new Configuration().configure().buildSessionFactory();

In two lines you are creating two configuration objects.

That should work(haven't tested) if you write,

Configuration  configuration = new Configuration().configure( "C:\\Users\\Nikolay_Tkachev\\workspace\\hiberTest\\src\\logic\\hibernate.cfg.xml");
return  configuration.buildSessionFactory();

But It fails after you deploy on the server,Since you are using system path than project relative path.

Here's another good solution on stackblitz.

Alternatively:

The accepted answer is a good solution, but it can be improved since your content/chat may often scroll to the bottom involuntarily given how the ngAfterViewChecked() lifecycle hook works.

Here's an improved version...

COMPONENT

import {..., AfterViewChecked, ElementRef, ViewChild, OnInit} from 'angular2/core'
@Component({
    ...
})
export class ChannelComponent implements OnInit, AfterViewChecked {
    @ViewChild('scrollMe') private myScrollContainer: ElementRef;

    /**Add the variable**/
    scrolledToBottom = false;

    ngAfterViewChecked() {        
        this.scrollToBottom();        
    } 

    scrollToBottom(): void {
        try {
          /**Add the condition**/
          if(!this.scrolledToBottom){
             this.myScrollContainer.nativeElement.scrollTop = this.myScrollContainer.nativeElement.scrollHeight;
          }   
        } catch(err) { }                 
    }

    /**Add the method**/
    onScroll(){
      this.scrolledToBottom = true;
    }
}

TEMPLATE

<!--Add a scroll event listener-->
<div #scrollMe 
     style="overflow: scroll; height: xyz;"
     (scroll)="onScroll()">
    <div class="..." 
        *ngFor="..."
        ...>  
    </div>
</div>

You can fade-in a box using jquery. Use bootstraps built in 'hide' class to effectively set display:none on the div element:

<div id="saveAlert" class="alert alert-success hide" data-alert="alert" style="top:0">
            <a class="close" href="#">×</a>
            <p><strong>Well done!</strong> You successfully read this alert message.</p>
        </div>

and then use the fadeIn function in jquery, like so:

$("#saveAlert").fadeIn();

There are also specify a duration for the fadeIn function, e.g: $("#saveAlert").fadeIn(400);

Full details on using the fadeIn function can be found on the official jQuery documentation site: http://api.jquery.com/fadeIn/

Just a sidenote as well, if you arent using jquery, you can either add the 'hide' class to your own CSS file, or just add this to your div:

 <div style="display:none;" id="saveAlert">

Your div will then basically be set to hidden as default, and then jQuery will perform the fadeIn action, forcing the div to be displayed.

The vblank_mode environment variable does the trick. You should then get several hundreds FPS on modern hardware. And you are now able to compare the results with others.

$>   vblank_mode=0 glxgears

I present you with the cleanest way ever, in the form of the world's smallest jquery plugin:

jQuery.fn.reverse = [].reverse;

Usage:

$('jquery-selectors-go-here').reverse().each(function () {
    //business as usual goes here
});

Command+K works fine in OSX to clear screen.

Shift+Command+K to clear only the scrollback buffer.

you must be using Laravel 5 the command

  class User_Controller extends Controller {
  public $restful = true;
  public function get_index(){
  return View('user.index');
  }
  }

and in routes.php

  Route::get('/', function()
  {
  return view('home.index');
  });

  Route::get('user', function()
  {
  return view('user.index');
  });

Laravel 5 command changes for view and controller see the documentation i was having same error before

using pendingRequests is not correct because as mentioned in Angular documentation, this property is primarily meant to be used for debugging purposes.

What I recommend is to use an interceptor to know if there is any active Async call.

module.config(['$httpProvider', function ($httpProvider) {
    $httpProvider.interceptors.push(function ($q, $rootScope) {
        if ($rootScope.activeCalls == undefined) {
            $rootScope.activeCalls = 0;
        }

        return {
            request: function (config) {
                $rootScope.activeCalls += 1;
                return config;
            },
            requestError: function (rejection) {
                $rootScope.activeCalls -= 1;
                return rejection;
            },
            response: function (response) {
                $rootScope.activeCalls -= 1;
                return response;
            },
            responseError: function (rejection) {
                $rootScope.activeCalls -= 1;
                return rejection;
            }
        };
    });
}]);

and then check whether activeCalls is zero or not in the directive through a $watch.

module.directive('loadingSpinner', function ($http) {
    return {
        restrict: 'A',
        replace: true,
        template: '<div class="loader unixloader" data-initialize="loader" data-delay="500"></div>',
        link: function (scope, element, attrs) {

            scope.$watch('activeCalls', function (newVal, oldVal) {
                if (newVal == 0) {
                    $(element).hide();
                }
                else {
                    $(element).show();
                }
            });
        }
    };
});

For Swift 4;

let uuid = NSUUID().uuidString.lowercased()

Why not set stdout directly to sys.stdout? And if you need to output to a log as well, then you can simply override the write method of f.

import sys
import subprocess

class SuperFile(open.__class__):

    def write(self, data):
        sys.stdout.write(data)
        super(SuperFile, self).write(data)

f = SuperFile("log.txt","w+")       
process = subprocess.Popen(command, stdout=f, stderr=f)

For Xcode 7, brandonscript has the correct answer.

For earlier versions:

1. Log in to the Apple Developer member centre and delete the profile there: https://developer.apple.com/account/ios/profile/profileList.action
2. In Xcode you go to Preferences > Accounts and click on your apple ID and View Details...
3. Then Sync your online provisioning profiles to your local machine and the deleted ones will be removed from the list:

I believe that there is an issue with git for Windows where git randomly writes the wrong line endings on checkout and the only workaround is to checkout some other branch and force git to ignore changes. Then checkout the branch you actually want to work on.

git checkout master -f
git checkout <your branch>

Be aware that this will discard any changes you might have intentionally made, so only do this if you have this problem immediately after checkout.

Edit: I might have actually got lucky the first time. It turns out that I got bit again after switching branches. It turned out that the files git was reporting as modified after changing branches was changing. (Apparently because git was not consistently applying the CRLF line ending to files properly.)

I updated to the latest git for Windows and hope the problem is gone.

Use

myString.split("\\s+");

This will work.

If the string you need to append is SVG and you add the proper namespace, you can parse the string as XML and append to the parent.

var xml = jQuery.parseXML('<circle xmlns="http://www.w3.org/2000/svg" cx="100" cy="50" r="40" stroke="black" stroke-width="2" fill="red"/>');
$("svg").append(xml.documentElement))

There's no reliable way to do this, as there are strings which stay the same through the encoding process, i.e. is "abc" encoded or not? There's no clear answer. Also, as you've encountered, some characters have multiple encodings... But...

Your decode-check-encode-check scheme fails due to the fact that some characters may be encoded in more than one way. However, a slight modification to your function should be fairly reliable, just check if the decode modifies the string, if it does, it was encoded.

It won't be fool proof of course, as "10+20=30" will return true (+ gets converted to space), but we're actually just doing arithmetic. I suppose this is what you're scheme is attempting to counter, I'm sorry to say that I don't think there's a perfect solution.

HTH.

Edit:
As I entioned in my own comment (just reiterating here for clarity), a good compromise would probably be to check for invalid characters in your url (e.g. space), and if there are some it's not encoded. If there are none, try to decode and see if the string changes. This still won't handle the arithmetic above (which is impossible), but it'll hopefully be sufficient.

For other people coming upon this post on google. There are 2 options, either merging or rebasing your branch. Both works differently, but have similar outcomes.

The accepted answer is a rebase. This will take all the commits done to our-team and then apply the commits done to featurex, prompting you to merge them as needed.

One bit caveat of rebasing is that you lose/rewrite your branch history, essentially telling git that your branch did not began at commit 123abc but at commit 456cde. This will cause problems for other people working on the branch, and some remote tools will complain about it. If you are sure about what you are doing though, that's what the --force flag is for.

What other posters are suggesting is a merge. This will take the featurex branch, with whatever state it has and try to merge it with the current state of our-team, prompting you to do one, big, merge commit and fix all the merge errors before pushing to our-team. The difference is that you are applying your featurex commits before the our-team new commits and then fixing the differences. You also do not rewrite history, instead adding one commit to it instead of rewriting those that came before.

Both options are valid and can work in tandem. What is usually (by that I mean, if you are using widespread tools and methodology such as git-flow) done for a feature branch is to merge it into the main branch, often going through a merge-request, and solve all the conflicts that arise into one (or multiple) merge commits.

Rebasing is an interesting option, that may help you fix your branch before eventually going through a merge, and ease the pain of having to do one big merge commit.

Bash 4+ examples. Note: not using quotes will cause issues when words contain spaces, etc. Always quote in Bash IMO.

Here are some examples Bash 4+:

Example 1, check for 'yes' in string (case insensitive):

if [[ "${str,,}" == *"yes"* ]] ;then

Example 2, check for 'yes' in string (case insensitive):

if [[ "$(echo "$str" | tr '[:upper:]' '[:lower:]')" == *"yes"* ]] ;then

Example 3, check for 'yes' in string (case sensitive):

 if [[ "${str}" == *"yes"* ]] ;then

Example 4, check for 'yes' in string (case sensitive):

 if [[ "${str}" =~ "yes" ]] ;then

Example 5, exact match (case sensitive):

 if [[ "${str}" == "yes" ]] ;then

Example 6, exact match (case insensitive):

 if [[ "${str,,}" == "yes" ]] ;then

Example 7, exact match:

 if [ "$a" = "$b" ] ;then

For me, it was the local overrides in Sources -> Overrides. A file gets saved locally whenever you change the styling of a page and chrome uses that file to override the server's css.
