Note that there are two reasons this might not work like you want it to. You may be aware of these, but I mention them just in case.

First, it won't affect a web browser, for example, that already has the current, "real" IP address resolved. So, it won't always take effect right away.

Second, it requires you to add an entry for every host name on a domain; just adding websitename.com will not block www.websitename.com, for example.

Add the jar file to your WEB-INF/lib folder. Right-click your project in Eclipse, and go to "Build Path > Configure Build Path" Add the "Web App Libraries" library This will ensure all WEB-INF/lib jars are included on the classpath. helped me..

Drag and drop in WEB-INF/lib folder and restart eclipse ans start webservice then create client

If you simply want to execute some code at the end of the loop, here's a slightly simpler variation that doesn't require extra event handling:

<div ng-controller="Ctrl">
  <div class="thing" ng-repeat="thing in things" my-post-repeat-directive>
    thing {{thing}}
  </div>
</div>

function Ctrl($scope) {
  $scope.things = [
    'A', 'B', 'C'  
  ];
}

angular.module('myApp', [])
.directive('myPostRepeatDirective', function() {
  return function(scope, element, attrs) {
    if (scope.$last){
      // iteration is complete, do whatever post-processing
      // is necessary
      element.parent().css('border', '1px solid black');
    }
  };
});

See a live demo.

When not told otherwise commands take over the foreground. You only have one "foreground" process running in a single shell session. The & symbol instructs commands to run in a background process and immediately returns to the command line for additional commands.

sh my_script.sh &

A background process will not stay alive after the shell session is closed. SIGHUP terminates all running processes. By default anyway. If your command is long-running or runs indefinitely (ie: microservice) you need to pr-pend it with nohup so it remains running after you disconnect from the session:

nohup sh my_script.sh &

EDIT: There does appear to be a gray area regarding the closing of background processes when & is used. Just be aware that the shell may close your process depending on your OS and local configurations (particularly on CENTOS/RHEL): https://serverfault.com/a/117157.

Match against the pattern and use the host language to invert the boolean result of the match. This will be much more legible and maintainable.

    This works but the value I get is multiplied times the screen density factor
  (1.5 for hdpi, 2.0 for xhdpi, etc).

I think it is good to get the value as per resolution but if you not want to do this give this in px.......

Density-independent pixel (dp)

A virtual pixel unit that you should use when defining UI layout, to express layout dimensions or position in a density-independent way. The density-independent pixel is equivalent to one physical pixel on a 160 dpi screen, which is the baseline density assumed by the system for a "medium" density screen. At runtime, the system transparently handles any scaling of the dp units, as necessary, based on the actual density of the screen in use. The conversion of dp units to screen pixels is simple: px = dp * (dpi / 160). For example, on a 240 dpi screen, 1 dp equals 1.5 physical pixels. You should always use dp units when defining your application's UI, to ensure proper display of your UI on screens with different densities.

I think it is good to change the value as per resolution but if you not want to do this give this in px.......

refer this link

as per this

dp

Density-independent Pixels - An abstract unit that is based on the physical density of the screen. These units are relative to a 160 dpi (dots per inch) screen, on which 1dp is roughly equal to 1px. When running on a higher density screen, the number of pixels used to draw 1dp is scaled up by a factor appropriate for the screen's dpi. Likewise, when on a lower density screen, the number of pixels used for 1dp is scaled down. The ratio of dp-to-pixel will change with the screen density, but not necessarily in direct proportion. Using dp units (instead of px units) is a simple solution to making the view dimensions in your layout resize properly for different screen densities. In other words, it provides consistency for the real-world sizes of your UI elements across different devices.

px

Pixels - Corresponds to actual pixels on the screen. This unit of measure is not recommended because the actual representation can vary across devices; each devices may have a different number of pixels per inch and may have more or fewer total pixels available on the screen.

In Intellij, I simple changed the name of the docker files to *.Dockerfile, and associated the file type *.Dockerfile to docker syntax.

The following code I use mostly for achieving the asked effect:

body {
    background-image: url('../images/bg.jpg');
    background-repeat: no-repeat;
    background-size: 100%;
}

In your broadcast receiver you could access a view via inflation a root layout from XML resource and then find all your views from this root layout with findViewByid():

View view = View.inflate(context, R.layout.ROOT_LAYOUT, null);

Now you can access your views via 'view' and cast them to your view type:

myImage = (ImageView) view.findViewById(R.id.my_image);

Not really related to this answer, but I'd ditch git pull, which just runs git fetch followed by git merge. You are doing three merges, which is going to make your Git run three fetch operations, when one fetch is all you will need. Hence:

git fetch origin   # update all our origin/* remote-tracking branches

git checkout demo         # if needed -- your example assumes you're on it
git merge origin/demo     # if needed -- see below

git checkout master
git merge origin/master

git merge -X theirs demo   # but see below

git push origin master     # again, see below

Controlling the trickiest merge

The most interesting part here is git merge -X theirs. As root545 noted, the -X options are passed on to the merge strategy, and both the default recursive strategy and the alternative resolve strategy take -X ours or -X theirs (one or the other, but not both). To understand what they do, though, you need to know how Git finds, and treats, merge conflicts.

A merge conflict can occur within some file¹ when the base version differs from both the current (also called local, HEAD, or --ours) version and the other (also called remote or --theirs) version of that same file. That is, the merge has identified three revisions (three commits): base, ours, and theirs. The "base" version is from the merge base between our commit and their commit, as found in the commit graph (for much more on this, see other StackOverflow postings). Git has then found two sets of changes: "what we did" and "what they did". These changes are (in general) found on a line-by-line, purely textual basis. Git has no real understanding of file contents; it is merely comparing each line of text.

These changes are what you see in git diff output, and as always, they have context as well. It's possible that things we changed are on different lines from things they changed, so that the changes seem like they would not collide, but the context has also changed (e.g., due to our change being close to the top or bottom of the file, so that the file runs out in our version, but in theirs, they have also added more text at the top or bottom).

If the changes happen on different lines—for instance, we change color to colour on line 17 and they change fred to barney on line 71—then there is no conflict: Git simply takes both changes. If the changes happen on the same lines, but are identical changes, Git takes one copy of the change. Only if the changes are on the same lines, but are different changes, or that special case of interfering context, do you get a modify/modify conflict.

The -X ours and -X theirs options tell Git how to resolve this conflict, by picking just one of the two changes: ours, or theirs. Since you said you are merging demo (theirs) into master (ours) and want the changes from demo, you would want -X theirs.

Blindly applying -X, however, is dangerous. Just because our changes did not conflict on a line-by-line basis does not mean our changes do not actually conflict! One classic example occurs in languages with variable declarations. The base version might declare an unused variable:

int i;

In our version, we delete the unused variable to make a compiler warning go away—and in their version, they add a loop some lines later, using i as the loop counter. If we combine the two changes, the resulting code no longer compiles. The -X option is no help here since the changes are on different lines.

If you have an automated test suite, the most important thing to do is to run the tests after merging. You can do this after committing, and fix things up later if needed; or you can do it before committing, by adding --no-commit to the git merge command. We'll leave the details for all of this to other postings.

¹You can also get conflicts with respect to "file-wide" operations, e.g., perhaps we fix the spelling of a word in a file (so that we have a change), and they delete the entire file (so that they have a delete). Git will not resolve these conflicts on its own, regardless of -X arguments.

Doing fewer merges and/or smarter merges and/or using rebase

There are three merges in both of our command sequences. The first is to bring origin/demo into the local demo (yours uses git pull which, if your Git is very old, will fail to update origin/demo but will produce the same end result). The second is to bring origin/master into master.

It's not clear to me who is updating demo and/or master. If you write your own code on your own demo branch, and others are writing code and pushing it to the demo branch on origin, then this first-step merge can have conflicts, or produce a real merge. More often than not, it's better to use rebase, rather than merge, to combine work (admittedly, this is a matter of taste and opinion). If so, you might want to use git rebase instead. On the other hand, if you never do any of your own commits on demo, you don't even need a demo branch. Alternatively, if you want to automate a lot of this, but be able to check carefully when there are commits that both you and others, made, you might want to use git merge --ff-only origin/demo: this will fast-forward your demo to match the updated origin/demo if possible, and simply outright fail if not (at which point you can inspect the two sets of changes, and choose a real merge or a rebase as appropriate).

This same logic applies to master, although you are doing the merge on master, so you definitely do need a master. It is, however, even likelier that you would want the merge to fail if it cannot be done as a fast-forward non-merge, so this probably also should be git merge --ff-only origin/master.

Let's say that you never do your own commits on demo. In this case we can ditch the name demo entirely:

git fetch origin   # update origin/*

git checkout master
git merge --ff-only origin/master || die "cannot fast-forward our master"

git merge -X theirs origin/demo || die "complex merge conflict"

git push origin master

If you are doing your own demo branch commits, this is not helpful; you might as well keep the existing merge (but maybe add --ff-only depending on what behavior you want), or switch it to doing a rebase. Note that all three methods may fail: merge may fail with a conflict, merge with --ff-only may not be able to fast-forward, and rebase may fail with a conflict (rebase works by, in essence, cherry-picking commits, which uses the merge machinery and hence can get a merge conflict).

Noneof the answers worked for me, I was getting "'HttpRequestBase' does not contain a definition for 'Query'", but this did work:

HttpContext.Current.Request.QueryString["index"]

Another solution is to use an Oracle Collection as a Hashmap:

declare 
-- create a type for your "Array" - it can be of any kind, record might be useful
  type hash_map is table of varchar2(1000) index by varchar2(30);
  my_hmap hash_map ;
-- i will be your iterator: it must be of the index's type
  i varchar2(30);
begin
  my_hmap('a') := 'apple';
  my_hmap('b') := 'box';
  my_hmap('c') := 'crow';
-- then how you use it:

  dbms_output.put_line (my_hmap('c')) ;

-- or to loop on every element - it's a "collection"
  i := my_hmap.FIRST;

  while (i is not null)  loop     
    dbms_output.put_line(my_hmap(i));      
    i := my_hmap.NEXT(i);
  end loop;

end;

FPM is a process manager to manage the FastCGI SAPI (Server API) in PHP.

Basically, it replaces the need for something like SpawnFCGI. It spawns the FastCGI children adaptively (meaning launching more if the current load requires it).

Otherwise, there's not much operating difference between it and FastCGI (The request pipeline from start of request to end is the same). It's just there to make implementing it easier.

sum = Double.parseDouble(""+marks.get(i));

I've tried the other answers listed above, but they are very far from decent solutions when dealing with large files -- especially once a single line's size occupies more than ~1/4 of available RAM.

Both bash and awk slurp the entire line, even though for this problem it's not needed. Bash will error out once a line is too long, even if you have enough memory.

I've implemented an extremely simple, fairly unoptimized python script that when tested with large files (~4 GB per line) doesn't slurp, and is by far a better solution than those given.

If this is time critical code for production, you can rewrite the ideas in C or perform better optimizations on the read call (instead of only reading a single byte at a time), after testing that this is indeed a bottleneck.

Code assumes newline is a linefeed character, which is a good assumption for Unix, but YMMV on Mac OS/Windows. Be sure the file ends with a linefeed to ensure the last line character count isn't overlooked.

from sys import stdin, exit

counter = 0
while True:
    byte = stdin.buffer.read(1)
    counter += 1
    if not byte:
        exit()
    if byte == b'\x0a':
        print(counter-1)
        counter = 0

The only thing you have to do is replace a registry value during the installation, I've done it about three times already, and every time found a different reference on-line, none here on stackoverflow.

There is no standard support for renaming properties in JavaScriptSerializer however you can quite easily add your own:

    }

    public string Name
    {
        get;
        set;
    }
}

The DataObject class then becomes:

public class DataObject
{
    [JsonProperty("user_id")]
    public int UserId { get; set; }

    [JsonProperty("detail_level")]
    public DetailLevel DetailLevel { get; set; }

I appreicate this might be a little late but thought other people wanting to use the JavaScriptSerializer rather than the DataContractJsonSerializer might appreciate it.

InputStream is used for reading, OutputStream for writing. They are connected as decorators to one another such that you can read/write all different types of data from all different types of sources.

For example, you can write primitive data to a file:

File file = new File("C:/text.bin");
file.createNewFile();
DataOutputStream stream = new DataOutputStream(new FileOutputStream(file));
stream.writeBoolean(true);
stream.writeInt(1234);
stream.close();

To read the written contents:

File file = new File("C:/text.bin");
DataInputStream stream = new DataInputStream(new FileInputStream(file));
boolean isTrue = stream.readBoolean();
int value = stream.readInt();
stream.close();
System.out.printlin(isTrue + " " + value);

You can use other types of streams to enhance the reading/writing. For example, you can introduce a buffer for efficiency:

DataInputStream stream = new DataInputStream(
    new BufferedInputStream(new FileInputStream(file)));

You can write other data such as objects:

MyClass myObject = new MyClass(); // MyClass have to implement Serializable
ObjectOutputStream stream = new ObjectOutputStream(
    new FileOutputStream("C:/text.obj"));
stream.writeObject(myObject);
stream.close();

You can read from other different input sources:

byte[] test = new byte[] {0, 0, 1, 0, 0, 0, 1, 1, 8, 9};
DataInputStream stream = new DataInputStream(new ByteArrayInputStream(test));
int value0 = stream.readInt();
int value1 = stream.readInt();
byte value2 = stream.readByte();
byte value3 = stream.readByte();
stream.close();
System.out.println(value0 + " " + value1 + " " + value2 + " " + value3);

For most input streams there is an output stream, also. You can define your own streams to reading/writing special things and there are complex streams for reading complex things (for example there are Streams for reading/writing ZIP format).

Harder Way (learning purpose) :

var number = 150
var percent= 10
var result = 0
for (var index = 0; index < number; index++) {
   const calculate = index / number * 100
   if (calculate == percent) result += index
}
return result

If the multiple csv files are zipped, you may use zipfile to read all and concatenate as below:

import zipfile
import pandas as pd

ziptrain = zipfile.ZipFile('yourpath/yourfile.zip')

train = []

train = [ pd.read_csv(ziptrain.open(f)) for f in ziptrain.namelist() ]

df = pd.concat(train)

    

This is an old thread, but I thought I would post this link, as it helped me quite a bit on this issue. Essentially what it's saying is the server configuration can override the php config. From the article:

For example mod_fastcgi has an option called "-idle-timeout" which controls the idle time of the script. So if the script does not output anything to the fastcgi handler for that many seconds then fastcgi would terminate it. The setup is somewhat like this:

Apache <-> mod_fastcgi <-> php processes

The article has other examples and further explanation. Hope this helps somebody else.

This is something I've also been struggling with for my own images. I have a server environment from which I create a Docker image. When I update the server, I'd like all users who are running containers based on my Docker image to be able to upgrade to the latest server.

Ideally, I'd prefer to generate a new version of the Docker image and have all containers based on a previous version of that image automagically update to the new image "in place." But this mechanism doesn't seem to exist.

So the next best design I've been able to come up with so far is to provide a way to have the container update itself--similar to how a desktop application checks for updates and then upgrades itself. In my case, this will probably mean crafting a script that involves Git pulls from a well-known tag.

The image/container doesn't actually change, but the "internals" of that container change. You could imagine doing the same with apt-get, yum, or whatever is appropriate for you environment. Along with this, I'd update the myserver:latest image in the registry so any new containers would be based on the latest image.

I'd be interested in hearing whether there is any prior art that addresses this scenario.

Since mysql_connect has been deprecated, connect and query instead with mysqli:

$mysqli = new mysqli("hostname","username","password","database_name");
$sqlSelect="SELECT your_fieldname FROM your_table";
$result = $mysqli -> query ($sqlSelect);

And then, if you have more than one option list with the same values on the same page, put the values in an array:

while ($row = mysqli_fetch_array($result)) {
    $rows[] = $row;
}

And then you can loop the array multiple times on the same page:

foreach ($rows as $row) {
    print "<option value='" . $row['your_fieldname'] . "'>" . $row['your_fieldname'] . "</option>";
}

I find the accepted answer, and all the others strange, since they pass self to an abstract class. An abstract class is not instantiated so can't have a self.

So try this, it works.

from abc import ABCMeta, abstractmethod


class Abstract(metaclass=ABCMeta):
    @staticmethod
    @abstractmethod
    def foo():
        """An abstract method. No need to write pass"""


class Derived(Abstract):
    def foo(self):
        print('Hooray!')


FOO = Derived()
FOO.foo()

AFAIK, {...} can only be used as a path, not inside a query-param. Try this instead:

public interface FooService {    

    @GET("/maps/api/geocode/json?sensor=false")
    void getPositionByZip(@Query("address") String address, Callback<String> cb);
}

If you have an unknown amount of parameters to pass, you can use do something like this:

public interface FooService {    

    @GET("/maps/api/geocode/json")
    @FormUrlEncoded
    void getPositionByZip(@FieldMap Map<String, String> params, Callback<String> cb);
}

Your logic is backwards.

SELECT 
    *
FROM 
    `test_table`
WHERE
        start_date NOT BETWEEN CAST('2009-12-15' AS DATE) and CAST('2010-01-02' AS DATE)
    AND end_date NOT BETWEEN CAST('2009-12-15' AS DATE) and CAST('2010-01-02' AS DATE)

Please install openssl from below link:

then set the variables below:

If you expect the data to be numeric in some form, and all you are interested in doing is converting the result to a numeric value, I would suggest:

for (Object o:list) {
  Double.parseDouble(o.toString);
}

If, running an Oracle HotSpot JDK 1.7.x, on a Linux platform where your locale suggests UTF-8 (e.g. LANG=en_US.utf8), if you don't set it on the command-line with -Dfile.encoding, the JDK will default file.encoding and the default Charset like this:

System.out.println(String.format("file.encoding: %s", System.getProperty("file.encoding")));
System.out.println(String.format("defaultCharset: %s", Charset.defaultCharset().name()));

... yields:

file.encoding: UTF-8
defaultCharset: UTF-8

... suggesting the default is UTF-8 on such a platform.

Additionally, if java.nio.charset.Charset.defaultCharset() finds file.encoding not-set, it looks for java.nio.charset.Charset.forName("UTF-8"), suggesting it prefers that string, although it is well-aliased, so "UTF8" will also work fine.

If you run the same program on the same platform with java -Dfile.encoding=UTF8, without the hypen, it yields:

file.encoding: UTF8
defaultCharset: UTF-8

... noting that the default charset has been canonicalized from UTF8 to UTF-8.

decimal Median(decimal[] xs) {
  Array.Sort(xs);
  return xs[xs.Length / 2];
}

Should do the trick.

-- EDIT --

For those who want the full monty, here is the complete, short, pure solution (a non-empty input array is assumed):

decimal Median(decimal[] xs) {
  var ys = xs.OrderBy(x => x).ToList();
  double mid = (ys.Count - 1) / 2.0;

If you have transaction logs in you MySQL, you can create a trigger for purpose of a log instance creation. A cronjob could monitor this log and based on events created by your trigger it could invoke a php script. That is if you absolutely have no control over you insertion.

There are some problems to import functions from other file.
First: You needn't to do this file executable. Better not to do so! just add

. file

to import all functions. And all of them will be as if they are defined in your file.
Second: You may be define the function with the same name. It will be overwritten. It's bad. You may declare like that

declare -f new_function_name=old_function_name 

and only after that do import. So you may call old function by new name.
Third: You may import only full list of functions defined in file. If some not needed you may unset them. But if you rewrite your functions after unset they will be lost. But if you set reference to it as described above you may restore after unset with the same name.
Finally In common procedure of import is dangerous and not so simple. Be careful! You may write script to do this more easier and safe. If you use only part of functions(not all) better split them in different files. Unfortunately this technique not made well in bash. In python for example and some other script languages it's easy and safe. Possible to make partial import only needed functions with its own names. We all want that in next bush versions will be done the same functionality. But now We must write many additional cod so as to do what you want.

In newer versions of pycharm u can do simply by right clicking on the directory or python package from which you want to import a file, then click on 'Mark Directory As' -> 'Sources Root'

PHP 7 isset() vs empty() vs is_null()

If you are using LESS, you can use Mixins for less code. Here I will add a gradient, border, and border-radius:

.navbar-inner {
  #gradient > .vertical(#ffffff, #ECECEC);
  border: #E2E2E2;
  .border-radius(6px);
}

SQL is implemented as if a query was executed in the following order:

1. FROM clause
2. WHERE clause
3. GROUP BY clause
4. HAVING clause
5. SELECT clause
6. ORDER BY clause

For most relational database systems, this order explains which names (columns or aliases) are valid because they must have been introduced in a previous step.

So in Oracle and SQL Server, you cannot use a term in the GROUP BY clause that you define in the SELECT clause because the GROUP BY is executed before the SELECT clause.

There are exceptions though: MySQL and Postgres seem to have additional smartness that allows it.

Create unique constraint that two numbers together CANNOT together be repeated:

ALTER TABLE someTable
ADD UNIQUE (col1, col2)

Have you checked the docstring of write()? It says:

write(str) -> None. Write string str to file.

Note that due to buffering, flush() or close() may be needed before the file on disk reflects the data written.

So you need to convert y to str first.

Also note that the string will be written at the current position which will be at the end of the file, because you'll already have read the old value. Use f.seek(0) to get to the beginning of the file.`

Edit: As for the IOError, this issue seems related. A cite from there:

For the modes where both read and writing (or appending) are allowed (those which include a "+" sign), the stream should be flushed (fflush) or repositioned (fseek, fsetpos, rewind) between either a reading operation followed by a writing operation or a writing operation followed by a reading operation.

So, I suggest you try f.seek(0) and maybe the problem goes away.

$_ is a variable created by the system usually inside block expressions that are referenced by cmdlets that are used with pipe such as Where-Object and ForEach-Object.

But it can be used also in other types of expressions, for example with Select-Object combined with expression properties. Get-ChildItem | Select-Object @{Name="Name";Expression={$_.Name}}. In this case the $_ represents the item being piped but multiple expressions can exist.

It can also be referenced by custom parameter validation, where a script block is used to validate a value. In this case the $_ represents the parameter value as received from the invocation.

The closest analogy to c# and java is the lamda expression. If you break down powershell to basics then everything is a script block including a script file a, functions and cmdlets. You can define your own parameters but in some occasions one is created by the system for you that represents the input item to process/evaluate. In those situations the automatic variable is $_.

I know this is an old question, but if you encounter this problem in MVC 3 then you can decorate your ActionMethod with [ValidateInput(false)] and just switch off request validation for a single ActionMethod, which is handy. And you don't need to make any changes to the web.config file, so you can still use the .NET 4 request validation everywhere else.

e.g.

[ValidateInput(false)]
public ActionMethod Edit(int id, string value)
{
    // Do your own checking of value since it could contain XSS stuff!
    return View();
}

Using a cookie to provide the CSRF token to the client does not allow a successful attack because the attacker cannot read the value of the cookie and therefore cannot put it where the server-side CSRF validation requires it to be.

The attacker will be able to cause a request to the server with both the auth token cookie and the CSRF cookie in the request headers. But the server is not looking for the CSRF token as a cookie in the request headers, it's looking in the payload of the request. And even if the attacker knows where to put the CSRF token in the payload, they would have to read its value to put it there. But the browser's cross-origin policy prevents reading any cookie value from the target website.

The same logic does not apply to the auth token cookie, because the server is expects it in the request headers and the attacker does not have to do anything special to put it there.

Video with fall back:

  video.srcObject = mediaSource;

I know question is already answered.

But let me add one point here. This is not only case of true or false. See below:

var val="Do";

Var c= (val == "Do" || val == "Done")
          ? 7
          : 0

Here if val is Do or Done then c will be 7 else it will be zero. In this case c will be 7.

This is actually another perspective of this operator.

I believe this answer is better:

If your top-level directory is called images, then run rm -r images/*. This uses the shell glob operator * to run rm -r on every file or directory within images.

basically you go up one level, and then say delete everything inside X directory. This way you are still specifying what folder should have its content deleted, which is safer than just saying 'delete everything here", while preserving the original folder, (which sometimes you want to because you aren't allowed or just don't want to modify the folder's existing permissions)

This is just an updated version of Jesse Webbs code that doesn't append the unnecessary trailing , character.

public static string PrintBytes(this byte[] byteArray)
{
    var sb = new StringBuilder("new byte[] { ");
    for(var i = 0; i < byteArray.Length;i++)
    {
        var b = byteArray[i];
        sb.Append(b);
        if (i < byteArray.Length -1)
        {
            sb.Append(", ");
        }
    }
    sb.Append(" }");
    return sb.ToString();
}

The output from this method would be:

new byte[] { 48, ... 135, 31, 178, 7, 157 }

XAMPP should have come with a "fake" sendmail program. In that case, you can use sendmail as well:

[mail function]
; For Win32 only.
; http://php.net/smtp
;SMTP = localhost
; http://php.net/smtp-port
;smtp_port = 25

; For Win32 only.
; http://php.net/sendmail-from
;sendmail_from = [email protected]

; For Unix only.  You may supply arguments as well (default: "sendmail -t -i").
; http://php.net/sendmail-path
sendmail_path = "C:/xampp/sendmail/sendmail.exe -t -i"

Sendmail should have a sendmail.ini with it; it should be configured as so:

# Example for a user configuration file

# Set default values for all following accounts.
defaults
logfile "C:\xampp\sendmail\sendmail.log"

# Mercury
#account Mercury
#host localhost
#from postmaster@localhost
#auth off

# A freemail service example
account ACCOUNTNAME_HERE
tls on
tls_certcheck off
host smtp.gmail.com
from EMAIL_HERE
auth on
user EMAIL_HERE
password PASSWORD_HERE

# Set a default account
account default : ACCOUNTNAME_HERE

Of course, replace ACCOUNTNAME_HERE with an arbitrary account name, replace EMAIL_HERE with a valid email (such as a Gmail or Hotmail), and replace PASSWORD_HERE with the password to your email. Now, you should be able to send mail. Remember to restart Apache (from the control panel or the batch files) to allow the changes to PHP to work.

EDIT: I am maintaining a similar, but more in-depth answer at: https://stackoverflow.com/a/28380690/895245

To see exactly what is happening, use nc -l and an user agent like a browser or cURL.

Save the form to an .html file:

<form action="http://localhost:8000" method="post" enctype="multipart/form-data">
  <p><input type="text" name="text" value="text default">
  <p><input type="file" name="file1">
  <p><input type="file" name="file2">
  <p><button type="submit">Submit</button>
</form>

Create files to upload:

echo 'Content of a.txt.' > a.txt
echo '<!DOCTYPE html><title>Content of a.html.</title>' > a.html

Run:

nc -l localhost 8000

Open the HTML on your browser, select the files and click on submit and check the terminal.

nc prints the request received. Firefox sent:

Aternativelly, cURL should send the same POST request as your a browser form:

nc -l localhost 8000
curl -F "text=default" -F "[email protected]" -F "[email protected]" localhost:8000

You can do multiple tests with:

while true; do printf '' | nc -l localhost 8000; done

apt-get update
apt-get upgrade 

by far the easiest way to upgrade on linux, works like a charm everytime.

+ theme(plot.title = element_text(size=22))

Here is the full set of things you can change in element_text:

element_text(family = NULL, face = NULL, colour = NULL, size = NULL,
  hjust = NULL, vjust = NULL, angle = NULL, lineheight = NULL,
  color = NULL)

If I understand your question correctly:

for elem in doc.findall('timeSeries/values/value'):
    print elem.get('dateTime'), elem.text

or if you prefer (and if there is only one occurrence of timeSeries/values:

values = doc.find('timeSeries/values')
for value in values:
    print value.get('dateTime'), elem.text

The findall() method returns a list of all matching elements, whereas find() returns only the first matching element. The first example loops over all the found elements, the second loops over the child elements of the values element, in this case leading to the same result.

I don't see where the problem with not finding timeSeries comes from however. Maybe you just forgot the getroot() call? (note that you don't really need it because you can work from the elementtree itself too, if you change the path expression to for example /timeSeriesResponse/timeSeries/values or //timeSeries/values)

OK, so big Props to Joel Muller for all his input. My ultimate solution was to use the Custom SessionStateModule detailed at the end of this MSDN article:

http://msdn.microsoft.com/en-us/library/system.web.sessionstate.sessionstateutility.aspx

This was:

• Very quick to implement (actually seemed easier than going the provider route)
• Used a lot of the standard ASP.Net session handling out of the box (via the SessionStateUtility class)

This has made a HUGE difference to the feeling of "snapiness" to our application. I still can't believe the custom implementation of ASP.Net Session locks the session for the whole request. This adds such a huge amount of sluggishness to websites. Judging from the amount of online research I had to do (and conversations with several really experienced ASP.Net developers), a lot of people have experienced this issue, but very few people have ever got to the bottom of the cause. Maybe I will write a letter to Scott Gu...

I hope this helps a few people out there!

String s1 = ""; means that the empty String is assigned to s1. In this case, s1.length() is the same as "".length(), which will yield 0 as expected.

String s2 = null; means that (null) or "no value at all" is assigned to s2. So this one, s2.length() is the same as null.length(), which will yield a NullPointerException as you can't call methods on null variables (pointers, sort of) in Java.

Also, a point, the statement

String s1;

Actually has the same effect as:

String s1 = null;

Whereas

String s1 = "";

Is, as said, a different thing.

This regular expression /^(\([0-9]{3}\)\s*|[0-9]{3}\-)[0-9]{3}-[0-9]{4}$/ validates all of the following:

'123-345-3456';
'(078)789-8908';
'(078) 789-8908'; // Note the space

To break down what's happening:

1. The group in the beginning validates two ways, either (XXX) or XXX-, with optionally spaces after the closing parenthesis.
2. The part after the group checks for XXX-XXX

You have a lot of pointless jQuery in there, but the $compile service is actually super simple in this case:

.directive( 'test', function ( $compile ) {
  return {
    restrict: 'E',
    scope: { text: '@' },
    template: '<p ng-click="add()">{{text}}</p>',
    controller: function ( $scope, $element ) {
      $scope.add = function () {
        var el = $compile( "<test text='n'></test>" )( $scope );
        $element.parent().append( el );
      };
    }
  };
});

You'll notice I refactored your directive too in order to follow some best practices. Let me know if you have questions about any of those.

Keep the h2 at the top, then pull-left on the p and pull-right on the login-box

<div class='container'>
  <div class='hero-unit'>

    <h2>Welcome</h2>

    <div class="pull-left">
      <p>Please log in</p>
    </div>

    <div id='login-box' class='pull-right control-group'>
        <div class='clearfix'>
            <input type='text' placeholder='Username' />
        </div>
        <div class='clearfix'>
            <input type='password' placeholder='Password' />
        </div>
        <button type='button' class='btn btn-primary'>Log in</button>
    </div>

    <div class="clearfix"></div>

  </div>
</div>

the default vertical-align on floated boxes is baseline, so the "Please log in" exactly lines up with the "Username" (check by changing the pull-right to pull-left).

I suspect the problem is the slashes in the format string versus the ones in the data. That's a culture-sensitive date separator character in the format string, and the final argument being null means "use the current culture". If you either escape the slashes ("M'/'d'/'yyyy") or you specify CultureInfo.InvariantCulture, it will be okay.

If anyone's interested in reproducing this:

// Works
DateTime dt = DateTime.ParseExact("9/1/2009", "M'/'d'/'yyyy", 
                                  new CultureInfo("de-DE"));

// Works
DateTime dt = DateTime.ParseExact("9/1/2009", "M/d/yyyy", 
                                  new CultureInfo("en-US"));

// Works
DateTime dt = DateTime.ParseExact("9/1/2009", "M/d/yyyy", 
                                  CultureInfo.InvariantCulture);

// Fails
DateTime dt = DateTime.ParseExact("9/1/2009", "M/d/yyyy", 
                                  new CultureInfo("de-DE"));

Using setInterval:

setInterval(function() {
    // your code goes here...
}, 60 * 1000); // 60 * 1000 milsec

The function returns an id you can clear your interval with clearInterval:

var timerID = setInterval(function() {
    // your code goes here...
}, 60 * 1000); 

clearInterval(timerID); // The setInterval it cleared and doesn't run anymore.

A "sister" function is setTimeout/clearTimeout look them up.

If you want to run a function on page init and then 60 seconds after, 120 sec after, ...:

function fn60sec() {
    // runs every 60 sec and runs on init.
}
fn60sec();
setInterval(fn60sec, 60*1000);

You can use:

SELECT IDENT_CURRENT('tablename')

to access the latest identity for a perticular table.

e.g. Considering following code:

INSERT INTO dbo.MyTable(columns....) VALUES(..........)

INSERT INTO dbo.YourTable(columns....) VALUES(..........)

SELECT IDENT_CURRENT('MyTable')

SELECT IDENT_CURRENT('YourTable')

This would yield to correct value for corresponding tables.

It returns the last IDENTITY value produced in a table, regardless of the connection that created the value, and regardless of the scope of the statement that produced the value.

IDENT_CURRENT is not limited by scope and session; it is limited to a specified table. IDENT_CURRENT returns the identity value generated for a specific table in any session and any scope.

Here's an update as of Nov 2014. I find that setting method='curl' did the trick for me (while method='auto', does not).

For example:

# does not work
download.file(url='https://s3.amazonaws.com/tripdata/201307-citibike-tripdata.zip',
              destfile='localfile.zip')

# does not work. this appears to be the default anyway
download.file(url='https://s3.amazonaws.com/tripdata/201307-citibike-tripdata.zip',
              destfile='localfile.zip', method='auto')

# works!
download.file(url='https://s3.amazonaws.com/tripdata/201307-citibike-tripdata.zip',
              destfile='localfile.zip', method='curl')

Please note that since Spring Boot 1.3.0.M1, you are able to build fully executable jars using Maven and Gradle.

For Maven, just include the following in your pom.xml:

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <configuration>
        <executable>true</executable>
    </configuration>
</plugin>

For Gradle add the following snippet to your build.gradle:

springBoot {
    executable = true
}

The fully executable jar contains an extra script at the front of the file, which allows you to just symlink your Spring Boot jar to init.d or use a systemd script.

init.d example:

$ln -s /var/yourapp/yourapp.jar /etc/init.d/yourapp

This allows you to start, stop and restart your application like:

$/etc/init.d/yourapp start|stop|restart

Or use a systemd script:

[Unit]
Description=yourapp
After=syslog.target

[Service]
ExecStart=/var/yourapp/yourapp.jar
User=yourapp
WorkingDirectory=/var/yourapp
SuccessExitStatus=143

[Install]
WantedBy=multi-user.target

More information at the following links:

• Installation as an init.d service
• Installation as a systemd service

If the entire program should stop use sys.exit() otherwise just use an empty return.

This works for me. Has a nice delayed action going on.

var $mouseX = 0, $mouseY = 0;
var $xp = 0, $yp =0;

$(document).mousemove(function(e){
    $mouseX = e.pageX;
    $mouseY = e.pageY;    
});

var $loop = setInterval(function(){
// change 12 to alter damping higher is slower
$xp += (($mouseX - $xp)/12);
$yp += (($mouseY - $yp)/12);
$("#moving_div").css({left:$xp +'px', top:$yp +'px'});  
}, 30);

Nice and simples

It depends on how and when you want to redirect the user to another page.

If you want to instantly redirect a user to another page without him seeing anything of a site in between, you should use the PHP header redirect method.

If you have a Javascript and some action of the user has to result in him entering another page, that is when you should use window.location.

The meta tag refresh is often used on download sites whenever you see these "Your download should start automatically" messages. You can let the user load a page, wait for a certain amount of time, then redirect him (e.g. to a to-be-downloaded file) without Javascript.

For me it was not running the minify task after concatenation as it expects concatenated input and it was not generated some times.

I tried adding to a default task in execution order and it didn't worked. It worked after adding just a return for each tasks and getting the minification inside gulp.start() like below.

/**
* Concatenate JavaScripts
*/
gulp.task('concat-js', function(){
    return gulp.src([
        'js/jquery.js',
        'js/jquery-ui.js',
        'js/bootstrap.js',
        'js/jquery.onepage-scroll.js',
        'js/script.js'])
    .pipe(maps.init())
    .pipe(concat('ux.js'))
    .pipe(maps.write('./'))
    .pipe(gulp.dest('dist/js'));
});

/**
* Minify JavaScript
*/
gulp.task('minify-js', function(){
    return gulp.src('dist/js/ux.js')
    .pipe(uglify())
    .pipe(rename('ux.min.js'))
    .pipe(gulp.dest('dist/js'));
});

gulp.task('concat', ['concat-js'], function(){
   gulp.start('minify-js');
});

gulp.task('default',['concat']);

For people using Kotlin you can put this in your MainActivity.kt:

window.navigationBarColor = ContextCompat.getColor(this@MainActivity, R.color.yourColor)

With window being:

val window: Window = [email protected]

Or you can put this in your themes.xml or styles.xml (requires API level 21):

<item name='android:navigationBarColor'>@color/yourColor</item>

An import is required, import scipy.io...

import scipy.io
mat = scipy.io.loadmat('file.mat')

As was in my case if your sql is generated by concatenating or uses converts then sql at execute need to be prefixed with letter N as below

e.g.

Exec N'Select bla..' 

the N defines string literal is unicode.

DECIMAL_DIG from <float.h> should give at least a reasonable approximation of that. Since that deals with decimal digits, and it's really stored in binary, you can probably store something a little larger without losing precision, but exactly how much is hard to say. I suppose you should be able to figure it out from FLT_RADIX and DBL_MANT_DIG, but I'm not sure I'd completely trust the result.

By using this query you can see all open transactions.

List All:

SHOW FULL PROCESSLIST  

if you want to kill a hang transaction copy transaction id and kill transaction by using this command:

KILL <id>    // e.g KILL 16543

(eg: div,footer,table) Right click -> Edit as HTML

Then you can copy and paster wherever you need...

that's all enjoy your coding.....

Many things has been told but for me simplest way is:

dpkg -l | grep packagename

First off: The variables a and b in the loops refer to numpy.ndarray objects.

In the first loop, a = a + 1 is evaluated as follows: the __add__(self, other) function of numpy.ndarray is called. This creates a new object and hence, A is not modified. Afterwards, the variable a is set to refer to the result.

In the second loop, no new object is created. The statement b += 1 calls the __iadd__(self, other) function of numpy.ndarray which modifies the ndarray object in place to which b is referring to. Hence, B is modified.

dim mydate = from cv in mydata.t1s
  select cv.date1 asc

datetime mindata = mydate[0];

If you want the complete URL e.g. website.com/workingdirectory/ use: window.location.hostname+window.location.pathname.replace(/[^\\\/]*$/, '');

Being aware of the two(?) different types of windows available in SQL Server Management Studio.

If you right-click a table and select Open it will use an editable grid that you can modify the cells in. If you right-click the database and select New Query it will create a slightly different type of window that you can't modify the grid in but it gives you a few other nice features, such as allowing different code snippets and letting you execute them separately by selection.

    WebElement button = driver.findElement(By.xpath("//button[@type='submit']"));
    int height = button.getSize().getHeight();
    int width = button.getSize().getWidth();
    Actions act = new Actions(driver);
    act.moveToElement(button).moveByOffset((width/2)+2,(height/2)+2).click();

You don't need to find the file.

Only write this instruction on terminal:

git config --global --edit

You can use this code

$(document).keypress(function(event){
    var keycode = (event.keyCode ? event.keyCode : event.which);
    if(keycode == '13'){
       alert('You pressed a ENTER key.');
    }
});

I would recommend you using the Conditional Attribute!

Update: 3.5 years later

You can use #if like this (example copied from MSDN):

// preprocessor_if.cs
#define DEBUG
#define VC_V7
using System;
public class MyClass 
{
    static void Main() 
    {
#if (DEBUG && !VC_V7)
        Console.WriteLine("DEBUG is defined");
#elif (!DEBUG && VC_V7)
        Console.WriteLine("VC_V7 is defined");
#elif (DEBUG && VC_V7)
        Console.WriteLine("DEBUG and VC_V7 are defined");
#else
        Console.WriteLine("DEBUG and VC_V7 are not defined");
#endif
    }
}

Only useful for excluding parts of methods.

If you use #if to exclude some method from compilation then you will have to exclude from compilation all pieces of code which call that method as well (sometimes you may load some classes at runtime and you cannot find the caller with "Find all references"). Otherwise there will be errors.

If you use conditional compilation on the other hand you can still leave all pieces of code that call the method. All parameters will still be validated by the compiler. The method just won't be called at runtime. I think that it is way better to hide the method just once and not have to remove all the code that calls it as well. You are not allowed to use the conditional attribute on methods which return value - only on void methods. But I don't think this is a big limitation because if you use #if with a method that returns a value you have to hide all pieces of code that call it too.

Here is an example:

    // calling Class1.ConditionalMethod() will be ignored at runtime 
    // unless the DEBUG constant is defined


    using System.Diagnostics;
    class Class1 
    {
       [Conditional("DEBUG")]
       public static void ConditionalMethod() {
          Console.WriteLine("Executed Class1.ConditionalMethod");
       }
    }

Summary:

I would use #ifdef in C++ but with C#/VB I would use Conditional attribute. This way you hide the method definition without having to hide the pieces of code that call it. The calling code is still compiled and validated by the compiler, the method is not called at runtime though. You may want to use #if to avoid dependencies because with Conditional attribute your code is still compiled.

You can also use something like

<c:if test="${ testObject.testPropert == "testValue" }">...</c:if>

1. Is it really a .ico, or is it just named ".ico"?
2. What browser are you testing in?

The absolutely easiest way to have a favicon is to place an icon called "favicon.ico" in the root folder. That just works everywhere, no code needed at all.

If you must have it in a subdirectory, use:

<link rel="shortcut icon" href="/img/favicon.ico" />

Note the / before img to ensure it is anchored to the root folder.

There are two basic techniques. The first uses PSAPI; MSDN has an example that uses EnumProcesses, OpenProcess, EnumProcessModules, and GetModuleBaseName.

The other uses Toolhelp, which I prefer. Use CreateToolhelp32Snapshot to get a snapshot of the process list, walk over it with Process32First and Process32Next, which provides module name and process ID, until you find the one you want, and then call OpenProcess to get a handle.

This may help:

public string NonBlankValueOf(string strTestString)
{
    return String.IsNullOrEmpty(strTestString)? "0": strTestString;
}

Use this to have a csv loaded into a list

import csv

csvfile = open(myfile, 'r')
reader = csv.reader(csvfile, delimiter='\t')
my_list = list(reader)
print my_list
>>>[['1st_line', '0'],
    ['2nd_line', '0']]

You could use a bit of workaround by placing a sass file in folder what you would like to import and import all files in that file like this:

file path:main/current/_current.scss

@import "placeholders"; @import "colors";

and in next dir level file you just use import for file what imported all files from that dir:

file path:main/main.scss

@import "EricMeyerResetCSSv20"; @import "clearfix"; @import "current";

That way you have same number of files, like you are importing the whole dir. Beware of order, file that comes last will override the matching stiles.

If you are using Rails 5 and above, the following solution will work.

#delete based on id
user_id = 50
User.find(id: user_id).delete_all

#delete based on condition
threshold_age = 20
User.where(age: threshold_age).delete_all

https://www.rubydoc.info/docs/rails/ActiveRecord%2FNullRelation:delete_all

Here is the simplest solution to your query

$date=date_create("2013-03-15"); // or your date string
date_add($date,date_interval_create_from_date_string("40 days"));// add number of days 
echo date_format($date,"Y-m-d"); //set date format of the result

I know this answer violates the terms of your question, but I think the correct answer to your intent is simply this: use whichever algorithm allows you the longest key length, then make sure you choose a really good key. Minor differences in the performance of most well regarded algorithms (cryptographically and chronologically) are overwhelmed by a few extra bits of a key.

I realize this question was posted a while ago; nonetheless, Bootstrap v4.0 has card layout support out of the box. You can find the documentation here: Bootstrap Card Layouts.

I've gotten back into using Bootstrap for a recent project that relies heavily on the card layout UI. I've found success with the following implementation across the standard breakpoints:

After trying both the Bootstrap .card-group and .card-deck card layout classes with quirky results at best across the standard breakpoints, I finally decided to give the .card-columns class a shot. And it worked!

Your results may vary, but .card-columns seems to be the most stable implementation here.

I found a very interesting issue with Android Studio and the mircrosoft upgrade to the web browser. I upgraded "stupidly" to the latest version of ie. of course Microsoft in their infinite wisdom knows exactly what to do with security. When I tried to compile my app I kept getting the error Gradle - build fails -- Execution failed for task. looking in the stack I saw that it did not recognize the path to java.exe. I found that odd as I was just able to compile the day before. I added JAVA_HOME to the env vars for the system, closed Android Studio and reopened it. Low and behold if the fire wall nag screen did not pop asking if I wanted to all jave.exe through.

What a cluster!

In JDK8

Stream<String> lines = Files.lines(path);
String data = lines.collect(Collectors.joining("\n"));
lines.close();

Generally what's meant by that is a fairly intimate familiarity with one (or probably more) of the .NET languages (C#, VB.NET, etc.) and one (or less probably more) of the .NET stacks (WinForms, ASP.NET, WPF, etc.).

As for a specific "formal definition", I don't think you'll find one beyond that. The job description should be specific about what they're looking for. I wouldn't consider a job listing that asks for a ".NET developer" and provides no more detail than that to be sufficiently descriptive.

I took what you had, and added another X-Testing header

var config = {headers:  {
        'Authorization': 'Basic d2VudHdvcnRobWFuOkNoYW5nZV9tZQ==',
        'Accept': 'application/json;odata=verbose',
        "X-Testing" : "testing"
    }
};

$http.get("/test", config);

And in the Chrome network tab, I see them being sent.

Are you not seeing them from the browser, or on the server? Try the browser tooling or a debug proxy and see what is being sent out.

var array = string.split(',')

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

In Node.js, you can set global variables via the "global" or "GLOBAL" object:

GLOBAL._ = require('underscore'); // But you "shouldn't" do this! (see note below)

or more usefully...

GLOBAL.window = GLOBAL;  // Like in the browser

From the Node.js source, you can see that these are aliased to each other:

node-v0.6.6/src/node.js:
28:     global = this;
128:    global.GLOBAL = global;

In the code above, "this" is the global context. With the CommonJS module system (which Node.js uses), the "this" object inside of a module (i.e., "your code") is not the global context. For proof of this, see below where I spew the "this" object and then the giant "GLOBAL" object.

console.log("\nTHIS:");
console.log(this);
console.log("\nGLOBAL:");
console.log(global);

/* Outputs ...

** Note: regarding setting "GLOBAL._", in general you should just do var _ = require('underscore');. Yes, you do that in every single file that uses Underscore.js, just like how in Java you do import com.foo.bar;. This makes it easier to figure out what your code is doing because the linkages between files are 'explicit'. It is mildly annoying, but a good thing. .... That's the preaching.

There is an exception to every rule. I have had precisely exactly one instance where I needed to set "GLOBAL._". I was creating a system for defining "configuration" files which were basically JSON, but were "written in JavaScript" to allow a bit more flexibility. Such configuration files had no 'require' statements, but I wanted them to have access to Underscore.js (the entire system was predicated on Underscore.js and Underscore.js templates), so before evaluating the "configuration", I would set "GLOBAL._". So yeah, for every rule, there's an exception somewhere. But you had better have a darn good reason and not just "I get tired of typing 'require', so I want to break with the convention".

Use:

import matplotlib.pyplot as plt

plt.gcf().subplots_adjust(bottom=0.15)

to make room for the label.

Edit:

Since i gave the answer, matplotlib has added the tight_layout() function. So i suggest to use it:

plt.tight_layout()

should make room for the xlabel.

It could be something like that:

var a = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j'];

Here is the optimised solution in Swift5, including handling the wrong indexPath. - Michael Lin Liu

• Step1. Get the indexPath of the current cell.
• Step2. Detect the velocity when scroll.
• Step3. Increase the indexPath's row when the velocity is increased.
• Step4. Tell the collection view to scroll to the next item

    func scrollViewWillEndDragging(_ scrollView: UIScrollView, withVelocity velocity: CGPoint, targetContentOffset: UnsafeMutablePointer<CGPoint>) {
        
        targetContentOffset.pointee = scrollView.contentOffset
        
        //M: Get the first visiable item's indexPath from visibaleItems.
        var indexPaths = *YOURCOLLECTIONVIEW*.indexPathsForVisibleItems
        indexPaths.sort()
        var indexPath = indexPaths.first!

        //M: Use the velocity to detect the paging control movement.
        //M: If the movement is forward, then increase the indexPath.
        if velocity.x > 0{
            indexPath.row += 1
            
            //M: If the movement is in the next section, which means the indexPath's row is out range. We set the indexPath to the first row of the next section.
            if indexPath.row == *YOURCOLLECTIONVIEW*.numberOfItems(inSection: indexPath.section){
                indexPath.row = 0
                indexPath.section += 1
            }
        }
        else{
            //M: If the movement is backward, the indexPath will be automatically changed to the first visiable item which is indexPath.row - 1. So there is no need to write the logic.
        }
        
        //M: Tell the collection view to scroll to the next item.
        *YOURCOLLECTIONVIEW*.scrollToItem(at: indexPath, at: .left, animated: true )
 }

try this..

$(element).find("option:contains(" + theText+ ")").attr('selected', 'selected');

This solution also works for NestedScrollView

NestedScrollView nestedScrollView = view.findViewById(R.id.YourNestedScrollViewID);
nestedScrollView.fullScroll(ScrollView.FOCUS_UP);

In XCode 10.1, I had to set "Library Search Paths" to something like $(PROJECT_DIR)/.../path/to/your/library

See section 5.1:

http://docs.python.org/library/stdtypes.html

Any object can be tested for truth value, for use in an if or while condition or as operand of the Boolean operations below. The following values are considered false:

None

False

zero of any numeric type, for example, 0, 0L, 0.0, 0j.

any empty sequence, for example, '', (), [].

any empty mapping, for example, {}.

instances of user-defined classes, if the class defines a __nonzero__() or __len__() method, when that method returns the integer zero or bool value False. [1]

All other values are considered true — so objects of many types are always true.

Operations and built-in functions that have a Boolean result always return 0 or False for false and 1 or True for true, unless otherwise stated. (Important exception: the Boolean operations or and and always return one of their operands.)

The other answers have pointed out the solution for the majority of cases involving PropertySources, but none have mentioned that certain property sources are unable to be casted into useful types.

One such example is the property source for command line arguments. The class that is used is SimpleCommandLinePropertySource. This private class is returned by a public method, thus making it extremely tricky to access the data inside the object. I had to use reflection in order to read the data and eventually replace the property source.

If anyone out there has a better solution, I would really like to see it; however, this is the only hack I have gotten to work.

You're missing your database name:

$sql = "SELECT ID, ListStID, ListEmail, Title FROM ".$entry_database." WHERE ID = ". $ReqBookID .";

And make sure that $entry_database isn't null or empty:

var_dump($entry_database);

Also notice that you don't need to have $ReqBookID in '' as if it's an Int.

The following will place the cursor back at beginning of the previous row. It's up to you to place it in the right horizontal position (using $pos.X to move it sideways):

$pos = $host.ui.RawUI.get_cursorPosition()
$pos.Y -= 1
$host.UI.RawUI.set_cursorPosition($Pos)

Your current output is 27 spaces over, so $pos.X = 27 might work.

Under use strict, say:

(my $new = $original) =~ s/foo/bar/;

instead.

If you don't want to jQuery, here's the vanilla JavaScript:

///Mute
var video = document.getElementById("your-video-id");
video.muted= true;

//Unmute
var video = document.getElementById("your-video-id");
video.muted= false;

It will work for audio too, just put the element's id and it will work (and change the var name if you want, to 'media' or something suited for both audio/video as you like).

I tried this:

import pandas as p
import numpy as n

closingValue = p.read_csv("<FILENAME>", usecols=[4], dtype=float)
print(closingValue)

Update (7 years later)

The reference cited in the original answer below was wrong. There is a built in function for this, which is exactly what kaiser suggests below: toLocaleString

So you can do:

(1234567.89).toLocaleString('en')              // for numeric input
parseFloat("1234567.89").toLocaleString('en')  // for string input

The function implemented below works, too, but simply isn't necessary.

(I thought perhaps I'd get lucky and find out that it was necessary back in 2010, but no. According to this more reliable reference, toLocaleString has been part of the standard since ECMAScript 3rd Edition [1999], which I believe means it would have been supported as far back as IE 5.5.)

Original Answer

According to this reference there isn't a built in function for adding commas to a number. But that page includes an example of how to code it yourself:

function addCommas(nStr) {
    nStr += '';
    var x = nStr.split('.');
    var x1 = x[0];
    var x2 = x.length > 1 ? '.' + x[1] : '';
    var rgx = /(\d+)(\d{3})/;
    while (rgx.test(x1)) {
            x1 = x1.replace(rgx, '$1' + ',' + '$2');
    }
    return x1 + x2;
}

Edit: To go the other way (convert string with commas to number), you could do something like this:

parseFloat("1,234,567.89".replace(/,/g,''))

The most useful thing you can do here is display/i $pc, before using stepi as already suggested in R Samuel Klatchko's answer. This tells gdb to disassemble the current instruction just before printing the prompt each time; then you can just keep hitting Enter to repeat the stepi command.

(See my answer to another question for more detail - the context of that question was different, but the principle is the same.)

When you say:

 #include <cstring>

the g++ compiler should put the <string.h> declarations it itself includes into the std:: AND the global namespaces. It looks for some reason as if it is not doing that. Try replacing one instance of strcpy with std::strcpy and see if that fixes the problem.

Sometimes npm install -g webpack does not save properly. Better to use npm install webpack --save . It worked for me.

The Substring has a parameter called startIndex. Set it according to the index you want to start at.

I don't think gcc has a flag for it, since it's primarily a compiler, but another of the GNU development tools does. objdump takes a -d/--disassemble flag:

$ objdump -d /path/to/binary

The disassembly looks like this:

080483b4 <main>:

 80483cf:   90                      nop

You can try

var browserZoomLevel = Math.round(window.devicePixelRatio * 100);

This will give you browser zoom percentage level on non-retina displays. For high DPI/retina displays, it would yield different values (e.g., 200 for Chrome and Safari, 140 for Firefox).

To catch zoom event you can use

$(window).resize(function() { 
// your code 
});

check this one out.

<input type="text" name="tree[tree2][height]">

<input type="text" name="tree[tree3][fruit]">

The DBA views are restricted. So you won't be able to query them unless you're connected as a DBA or similarly privileged user.

The ALL views show you the information you're allowed to see. Normally that would be jobs you've submitted, unless you have additional privileges.

The privileges you need are defined in the Admin Guide. Find out more.

So, either you need a DBA account or you need to chat with your DBA team about getting access to the information you need.

you want to work onMessageReceived(RemoteMessage remoteMessage) in background send only data part notification part this:

"data":    "image": "",    "message": "Firebase Push Message Using API", 

"AnotherActivity": "True", "to" : "device id Or Device token"

By this onMessageRecivied is call background and foreground no need to handle notification using notification tray on your launcher activity. Handle data payload in using this:

  public void onMessageReceived(RemoteMessage remoteMessage)
    if (remoteMessage.getData().size() > 0) 
    Log.d(TAG, "Message data payload: " + remoteMessage.getData());      

I think you just need COUNT(DISTINCT post_id) FROM votes.

See "4.2.7. Aggregate Expressions" section in http://www.postgresql.org/docs/current/static/sql-expressions.html.

EDIT: Corrected my careless mistake per Erwin's comment.

It can be done with LinearLayout (less overhead and more control than the Relative Layout option). Give the second view the remaining space so gravity can work. Tested back to API 16.

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Aligned left" />

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="end"
        android:text="Aligned right" />
</LinearLayout> 

If you want to limit the size of the first text view, do this:

Adjust weights as required. Relative layout won't allow you to set a percentage weight like this, only a fixed dp of one of the views

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:text="Aligned left but too long and would squash the other view" />

    <TextView
        android:layout_width="0dp"
        android:layout_weight="1"
        android:layout_height="wrap_content"
        android:gravity="end"
        android:text="Aligned right" />
</LinearLayout>

for ( i = 0; i < total.length; i++ ); // remove this
{
    if (total[i]!=0)
        System.out.println( "Letter" + (char)( 'a' + i) + " count =" + total[i]);
}

The for loop loops until i=26 (where 26 is total.length) and then your if is executed, going over the bounds of the array. Remove the ; at the end of the for loop.

There are a few good answers posted here, but I think you can simplify your code and skip the check for inputElement.selectionStart support: it is not supported only on IE8 and earlier (see documentation) which represents less than 1% of the current browser usage.

var input = document.getElementById('myinput'); // or $('#myinput')[0]
var caretPos = input.selectionStart;

// and if you want to know if there is a selection or not inside your input:

if (input.selectionStart != input.selectionEnd)
{
    var selectionValue =
    input.value.substring(input.selectionStart, input.selectionEnd);
}

For text:

[RangeObject].Font.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

For cell background

[RangeObject].Interior.Color = System.Drawing.ColorTranslator.ToOle(System.Drawing.Color.Red);

From the docs, to send HTML e-mail you want to use alternative content-types, like this:

from django.core.mail import EmailMultiAlternatives

subject, from_email, to = 'hello', '[email protected]', '[email protected]'
text_content = 'This is an important message.'
html_content = '<p>This is an <strong>important</strong> message.</p>'
msg = EmailMultiAlternatives(subject, text_content, from_email, [to])
msg.attach_alternative(html_content, "text/html")
msg.send()

You'll probably want two templates for your e-mail - a plain text one that looks something like this, stored in your templates directory under email.txt:

Hello {{ username }} - your account is activated.

and an HTMLy one, stored under email.html:

Hello <strong>{{ username }}</strong> - your account is activated.

You can then send an e-mail using both those templates by making use of get_template, like this:

from django.core.mail import EmailMultiAlternatives
from django.template.loader import get_template
from django.template import Context

plaintext = get_template('email.txt')
htmly     = get_template('email.html')

d = Context({ 'username': username })

subject, from_email, to = 'hello', '[email protected]', '[email protected]'
text_content = plaintext.render(d)
html_content = htmly.render(d)
msg = EmailMultiAlternatives(subject, text_content, from_email, [to])
msg.attach_alternative(html_content, "text/html")
msg.send()

In EntityFramework Core 2.x there is no need for Attach:

 // get a tracked entity
 var entity = context.User.Find(userId);
 entity.someProp = someValue;
 // other property changes might come here
 context.SaveChanges();

Tried this in SQL Server and profiling it:

exec sp_executesql N'SET NOCOUNT ON;
UPDATE [User] SET [someProp] = @p0
WHERE [UserId] = @p1;
SELECT @@ROWCOUNT;

',N'@p1 int,@p0 bit',@p1=1223424,@p0=1

Find ensures that already loaded entities do not trigger a SELECT and also automatically attaches the entity if needed (from the docs):

    ///     Finds an entity with the given primary key values. If an entity with the given primary key values
    ///     is being tracked by the context, then it is returned immediately without making a request to the
    ///     database. Otherwise, a query is made to the database for an entity with the given primary key values
    ///     and this entity, if found, is attached to the context and returned. If no entity is found, then
    ///     null is returned.

if the zipcode field is not a required field then add null=True and blank=True, then run makemigrations and migrate command to successfully reflect the changes in the database.

A Y-combinator is a "functional" (a function that operates on other functions) that enables recursion, when you can't refer to the function from within itself. In computer-science theory, it generalizes recursion, abstracting its implementation, and thereby separating it from the actual work of the function in question. The benefit of not needing a compile-time name for the recursive function is sort of a bonus. =)

This is applicable in languages that support lambda functions. The expression-based nature of lambdas usually means that they cannot refer to themselves by name. And working around this by way of declaring the variable, refering to it, then assigning the lambda to it, to complete the self-reference loop, is brittle. The lambda variable can be copied, and the original variable re-assigned, which breaks the self-reference.

Y-combinators are cumbersome to implement, and often to use, in static-typed languages (which procedural languages often are), because usually typing restrictions require the number of arguments for the function in question to be known at compile time. This means that a y-combinator must be written for any argument count that one needs to use.

Below is an example of how the usage and working of a Y-Combinator, in C#.

Using a Y-combinator involves an "unusual" way of constructing a recursive function. First you must write your function as a piece of code that calls a pre-existing function, rather than itself:

// Factorial, if func does the same thing as this bit of code...
x == 0 ? 1: x * func(x - 1);

Then you turn that into a function that takes a function to call, and returns a function that does so. This is called a functional, because it takes one function, and performs an operation with it that results in another function.

// A function that creates a factorial, but only if you pass in
// a function that does what the inner function is doing.
Func<Func<Double, Double>, Func<Double, Double>> fact =
  (recurs) =>
    (x) =>
      x == 0 ? 1 : x * recurs(x - 1);

Now you have a function that takes a function, and returns another function that sort of looks like a factorial, but instead of calling itself, it calls the argument passed into the outer function. How do you make this the factorial? Pass the inner function to itself. The Y-Combinator does that, by being a function with a permanent name, which can introduce the recursion.

// One-argument Y-Combinator.
public static Func<T, TResult> Y<T, TResult>(Func<Func<T, TResult>, Func<T, TResult>> F)
{
  return
    t =>  // A function that...
      F(  // Calls the factorial creator, passing in...
        Y(F)  // The result of this same Y-combinator function call...
              // (Here is where the recursion is introduced.)
        )
      (t); // And passes the argument into the work function.
}

Rather than the factorial calling itself, what happens is that the factorial calls the factorial generator (returned by the recursive call to Y-Combinator). And depending on the current value of t the function returned from the generator will either call the generator again, with t - 1, or just return 1, terminating the recursion.

It's complicated and cryptic, but it all shakes out at run-time, and the key to its working is "deferred execution", and the breaking up of the recursion to span two functions. The inner F is passed as an argument, to be called in the next iteration, only if necessary.

As the other answers said, the function you need is cv2.rectangle(), but keep in mind that the coordinates for the bounding box vertices need to be integers if they are in a tuple, and they need to be in the order of (left, top) and (right, bottom). Or, equivalently, (xmin, ymin) and (xmax, ymax).

have you tried display:inline-block;?

I came across a similar issue but instead of changing the regedit I decided to change the Chrome settings

Try the following steps

1. In the chrome browser type: chrome://plugins/
2. Click on + Details (top right corner) to expand all the plugin details.
3. Find Java and click on Disable for the path(s) that you don't want to be used.

You might have to restart the browser to see the changes. This also assumes that the Java that you have enabled is the latest Java.

Hope this helps

you can have the return as an object. You create that object 'on fly' in your

function: if(int) 
 return new object(){
   int nr=..
}

same for string. But I am concerned that is an expensive solution...

I had this issue; I fixed it by going to

Computer-->Properties-->Advanced Settings-->Environmental Variables

In the System Variables find the variable named PATH.
-->Select Edit -->At the very end of the Path Variable, put a ";" then add your path of your JDK and put \bin\ at the end

Should be fixed.

Example:

System Variable-

C:\Program Files (x86)\Common Files.......HP\LeanFT\bin

JDK path-

C:\Programs Files\Java\jre1.8.0_121

Final Path -

C:\Program Files (x86)\Common Files.......HP\LeanFT\bin;C:\Programs Files\Java\jre1.8.0_121\bin\

Sources: https://www.java.com/en/download/help/path.xml

Thought I'd add the Centos installs:

sudo yum -y install gcc gcc-c++ 
sudo yum -y install zlib zlib-devel
sudo yum -y install libffi-devel 

Check python version:

python3 -V

Create virtualenv:

virtualenv -p python3 venv

To plot an equation that is not solved for a specific variable (like circle or hyperbola):

xlist = np.linspace(-2.0, 2.0, 100) # Create 1-D arrays for x,y dimensions
ylist = np.linspace(-2.0, 2.0, 100) 
X,Y = np.meshgrid(xlist, ylist) # Create 2-D grid xlist,ylist values
F = X**2 + Y**2 - 1  #  'Circle Equation
plt.contour(X, Y, F, [0], colors = 'k', linestyles = 'solid')
plt.show()

const unsigned attribName = getname();
const unsigned attribVal = getvalue();
const char *attrName=NULL, *attrVal=NULL;
attrName = (const char*) attribName;
attrVal = (const char*) attribVal;

If the value is hardcoded in the source of the page using the value attribute then you can

$('#attached_docs :input[value="123"]').remove();

If you want to target elements that have a value of 123, which was set by the user or programmatically then use EDIT works both ways ..

or

$('#attached_docs :input').filter(function(){return this.value=='123'}).remove();

demo http://jsfiddle.net/gaby/RcwXh/2/

Try this

keys = [next(iter(x.keys())) for x in test]
print(list(keys))

The result looks like this. ['foo', 'hello']

You can find more possible solutions here.

I've done this in the past.

Either do it manually, (build a nice gui that helps the user do it quickly) or have it automated and check against a recent address database (you have to buy that) and manually handle errors.

Manual handling will take about 10 seconds each, meaning you can do 3600/10 = 360 per hour, so 4000 should take you approximately 11-12 hours. This will give you a high rate of accuracy.

For automation, you need a recent US address database, and tweak your rules against that. I suggest not going fancy on the regex (hard to maintain long-term, so many exceptions). Go for 90% match against the database, do the rest manually.

Do get a copy of Postal Addressing Standards (USPS) at http://pe.usps.gov/cpim/ftp/pubs/Pub28/pub28.pdf and notice it is 130+ pages long. Regexes to implement that would be nuts.

For international addresses, all bets are off. US-based workers would not be able to validate.

Alternatively, use a data service. I have, however, no recommendations.

Furthermore: when you do send out the stuff in the mail (that's what it's for, right?) make sure you put "address correction requested" on the envelope (in the right place) and update the database. (We made a simple gui for the front desk person to do that; the person who actually sorts through the mail)

Finally, when you have scrubbed data, look for duplicates.

If you are using a version of jQuery that is less than version 1.8 you can use the $('.class').size() which takes zero parameters. See documentation for more information on .size() method.

However if you are using (or plan to upgrade) to 1.8 or greater you can use $('.class').length property. See documentation for more information on .length property.

In python notebooks I often want to filter out 'dangling' numpy.ndarray's, in particular the ones that are stored in _1, _2, etc that were never really meant to stay alive.

I use this code to get a listing of all of them and their size.

Not sure if locals() or globals() is better here.

import sys
import numpy
from humanize import naturalsize

for size, name in sorted(
    (value.nbytes, name)
    for name, value in locals().items()
    if isinstance(value, numpy.ndarray)):
  print("{:>30}: {:>8}".format(name, naturalsize(size)))

Even though you've got your answer, for those that find this question, it is also possible to open an Excel spreadsheet as a JET data store. Borrowing the connection string from a project I've used it on, it will look kinda like this:

strExcelConn = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & objFile.Path & ";Extended Properties=""Excel 8.0;HDR=Yes"""
strSQL = "SELECT * FROM [RegistrationList$] ORDER BY DateToRegister DESC"

Note that "RegistrationList" is the name of the tab in the workbook. There are a few tutorials floating around on the web with the particulars of what you can and can't do accessing a sheet this way.

Just thought I'd add. :)

On Linux/unix/MacOSX use core files (you can enable them with ulimit or compatible system call). On Windows use Microsoft error reporting (you can become a partner and get access to your application crash data).

I encounter similar situation. I would like to have background of the last .item to be yellow in the elements that look like...

<div class="container">
  <div class="item">item 1</div>
  <div class="item">item 2</div>
  <div class="item">item 3</div>
  ...
  <div class="item">item x</div>
  <div class="other">I'm here for some reasons</div>
</div>

I use nth-last-child(2) to achieve it.

.item:nth-last-child(2) {
  background-color: yellow;
}

It strange to me because nth-last-child of item suppose to be the second of the last item but it works and I got the result as I expect. I found this helpful trick from CSS Trick

You can use [DisplayMatrics][1] and determine the screen density. Something like this:

int pixelsValue = 5; // margin in pixels
float d = context.getResources().getDisplayMetrics().density;
int margin = (int)(pixelsValue * d);

As I remember it's better to use flooring for offsets and rounding for widths.

Often, a Python program is run by naming a .py file on the command line:

$ python my_program.py

You can also create a directory or zipfile full of code, and include a __main__.py. Then you can simply name the directory or zipfile on the command line, and it executes the __main__.py automatically:

$ python my_program_dir
$ python my_program.zip
# Or, if the program is accessible as a module
$ python -m my_program

You'll have to decide for yourself whether your application could benefit from being executed like this.

Note that a __main__ module usually doesn't come from a __main__.py file. It can, but it usually doesn't. When you run a script like python my_program.py, the script will run as the __main__ module instead of the my_program module. This also happens for modules run as python -m my_module, or in several other ways.

If you saw the name __main__ in an error message, that doesn't necessarily mean you should be looking for a __main__.py file.

if you have

<span class="label label-default">New</span>

just add the style="font-size:XXpx;", ej.

<span class="label label-default" style="font-size:15px;">New</span>

A simple solution that no one else has said but worked for me was not running without sudo or not as root.

Just loop...

foreach(var table in DataSet1.Tables) {
    foreach(var col in table.Columns) {
       ...
    }
    foreach(var row in table.Rows) {
        object[] values = row.ItemArray;
        ...
    }
}

Yes you can do that.

Materials you need:

1. WebServer
2. A Database Stored in the webserver
3. And a little bit android knowledge :)
4. Webservices (json ,Xml...etc) whatever you are comfortable with

1. First set the internet permissions in your manifest file

 <uses-permission android:name="android.permission.INTERNET" />

2. Make a class to make an HTTPRequest from the server (i am using json parisng to get the values)

for eg:

    public class JSONfunctions {

    public static JSONObject getJSONfromURL(String url) {
        InputStream is = null;
        String result = "";
        JSONObject jArray = null;

        // Download JSON data from URL
        try {
            HttpClient httpclient = new DefaultHttpClient();
            HttpPost httppost = new HttpPost(url);
            HttpResponse response = httpclient.execute(httppost);
            HttpEntity entity = response.getEntity();
            is = entity.getContent();

        } catch (Exception e) {
            Log.e("log_tag", "Error in http connection " + e.toString());
        }

        // Convert response to string
        try {
            BufferedReader reader = new BufferedReader(new InputStreamReader(
                    is, "iso-8859-1"), 8);
            StringBuilder sb = new StringBuilder();
            String line = null;
            while ((line = reader.readLine()) != null) {
                sb.append(line + "\n");
            }
            is.close();
            result = sb.toString();
        } catch (Exception e) {
            Log.e("log_tag", "Error converting result " + e.toString());
        }

        try {

            jArray = new JSONObject(result);
        } catch (JSONException e) {
            Log.e("log_tag", "Error parsing data " + e.toString());
        }

        return jArray;
    }
}

3. In your MainActivity Make an object of the class JsonFunctions and pass the url as an argument from where you want to get the data

eg:

JSONObject jsonobject;

jsonobject = JSONfunctions.getJSONfromURL("http://YOUR_DATABASE_URL");

4. And then finally read the jsontags and store the values in an arraylist and later show it in listview if you want

and if you have any problem you can follow this blog he gives excellent android tutorials AndroidHive

Since the above answer i wrote was long back and now HttpClient, HttpPost,HttpEntity have been removed in Api 23. You can use the below code in the build.gradle(app-level) to still continue using org.apache.httpin your project.

android {
    useLibrary 'org.apache.http.legacy'
    signingConfigs {}
    buildTypes {}
}

or You can use HttpURLConnection like below to get your response from server

public String getJSON(String url, int timeout) {
HttpURLConnection c = null;
try {
    URL u = new URL(url);
    c = (HttpURLConnection) u.openConnection();
    c.setRequestMethod("GET");
    c.setRequestProperty("Content-length", "0");
    c.setUseCaches(false);
    c.setAllowUserInteraction(false);
    c.setConnectTimeout(timeout);
    c.setReadTimeout(timeout);
    c.connect();
    int status = c.getResponseCode();

    switch (status) {
        case 200:
        case 201:
            BufferedReader br = new BufferedReader(new InputStreamReader(c.getInputStream()));
            StringBuilder sb = new StringBuilder();
            String line;
            while ((line = br.readLine()) != null) {
                sb.append(line+"\n");
            }
            br.close();
            return sb.toString();
    }

} catch (MalformedURLException ex) {
    Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
} catch (IOException ex) {
    Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
} finally {
   if (c != null) {
      try {
          c.disconnect();
      } catch (Exception ex) {
         Logger.getLogger(getClass().getName()).log(Level.SEVERE, null, ex);
      }
   }
}
return null;

}

or You can use 3rd party Library like Volley, Retrofit to call the webservice api and get the response and later parse it with using FasterXML-jackson, google-gson.

If you only have access to the view object, then you can get the parameters defined in the URL path this way:

view.kwargs.get('url_param')

If you only have access to the request object, use the following:

request.resolver_match.kwargs.get('url_param')

Tested on Django 3.

I had to explicitly call out the dependency for my json library in my POM.

Add the below code inside an onCreate function in your activity.

As King King said, you must add the browser specific prefix. This should cover most browsers:

Use a ByteArrayOutputStream. Here is the process:

• Get an InputStream to read data
• Create a ByteArrayOutputStream.
• Copy all the InputStream into the OutputStream
• Get your byte[] from the ByteArrayOutputStream using the toByteArray() method

@Synxmax's answer is correct when using a Service and the MediaPlayer class, however you also need to declare the Service in the Manifest for this to work, like so:

<service
    android:enabled="true"
    android:name="com.package.name.BackgroundSoundService" />

If you want to show all the rows set like bellow

pd.options.display.max_rows = None

If you want to show all columns set like bellow

pd.options.display.max_columns = None

You can also use window.location.href=window.location.href;

if you are loading file in static method then ClassLoader classLoader = getClass().getClassLoader(); this might give you an error.

You can try this e.g. file you want to load from resources is resources >> Images >> Test.gif

import org.springframework.core.io.ClassPathResource;
import org.springframework.core.io.Resource;

Resource resource = new ClassPathResource("Images/Test.gif");

    File file = resource.getFile();

PhysicalAddressDictionary.TryGetValue

 public bool TryGetValue (
    PhysicalAddressKey key,
    out PhysicalAddressEntry physicalAddress
     )

I have tried this code and It's working fine in my case.

DELETE FROM NG_USR_0_CLIENT_GRID_NEW WHERE rowid IN
( SELECT rowid FROM
  (
      SELECT wi_name, relationship, ROW_NUMBER() OVER (ORDER BY rowid DESC) RN
      FROM NG_USR_0_CLIENT_GRID_NEW
      WHERE wi_name = 'NB-0000001385-Process'
  )
  WHERE RN=2
);

Add this line in your Manifest where your Activity is called

android:windowSoftInputMode="adjustPan|adjustResize"

or

you can add this line in your onCreate

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE|WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

A few years ago I inherited a python (2.7.1) project running under Django-1.2.3 and now was asked to enhance it with QR possibilities. Got the same problem and did not find pip or apt-get either. So I solved it in a totally different but easy way. I /bin/vi-ed the setup.py and changed the line "from setuptools import setup" into: "from distutils.core import setup" That did it for me, so I thought I should post this for other users running old pythons.

numpy.random.randint accepts a third argument (size) , in which you can specify the size of the output array. You can use this to create your DataFrame -

df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))

Here - np.random.randint(0,100,size=(100, 4)) - creates an output array of size (100,4) with random integer elements between [0,100) .

Demo -

import numpy as np
import pandas as pd
df = pd.DataFrame(np.random.randint(0,100,size=(100, 4)), columns=list('ABCD'))

which produces:

     A   B   C   D
0   45  88  44  92
1   62  34   2  86
2   85  65  11  31
3   74  43  42  56
4   90  38  34  93
5    0  94  45  10
6   58  23  23  60
..  ..  ..  ..  ..

Normally, I would go with what the documentation says but if the instructor explicitly said to stick with JDK 6, I'd use JDK 6 because you would want your development environment to be as close as possible to the instructors. It would suck if you ran into an issue and having the thought in the back of your head that maybe it's because you're on JDK 7 that you're having the issue. Btw, I haven't touched Android recently but I personally never ran into issues when I was on JDK 7 but mind you, I only code Android apps casually.

If you are running in Android 29 then you have to use scoped storage or for now, you can bypass this issue by using:

android:requestLegacyExternalStorage="true"

in manifest in the application tag.

It's easy enough to "roll your own" version of a dictionary that allows "duplicate key" entries. Here is a rough simple implementation. You might want to consider adding support for basically most (if not all) on IDictionary<T>.

public class MultiMap<TKey,TValue>
{
    private readonly Dictionary<TKey,IList<TValue>> storage;

    public MultiMap()
    {
        storage = new Dictionary<TKey,IList<TValue>>();
    }

    public void Add(TKey key, TValue value)
    {
        if (!storage.ContainsKey(key)) storage.Add(key, new List<TValue>());
        storage[key].Add(value);
    }

    public IEnumerable<TKey> Keys
    {
        get { return storage.Keys; }
    }

    public bool ContainsKey(TKey key)
    {
        return storage.ContainsKey(key);
    }

    public IList<TValue> this[TKey key]
    {
        get
        {
            if (!storage.ContainsKey(key))
                throw new KeyNotFoundException(
                    string.Format(
                        "The given key {0} was not found in the collection.", key));
            return storage[key];
        }
    }
}

A quick example on how to use it:

const string key = "supported_encodings";
var map = new MultiMap<string,Encoding>();
map.Add(key, Encoding.ASCII);
map.Add(key, Encoding.UTF8);
map.Add(key, Encoding.Unicode);

foreach (var existingKey in map.Keys)
{
    var values = map[existingKey];
    Console.WriteLine(string.Join(",", values));
}

i've used this

function notIE(){
    var ua = window.navigator.userAgent;
    if (ua.indexOf('Edge/') > 0 || 
        ua.indexOf('Trident/') > 0 || 
        ua.indexOf('MSIE ') > 0){
       return false;
    }else{
        return true;                
    }
}

Definitely in Modules.

• Sheets can be deleted, copied and moved with surprising results.
• You can't call code in sheet "code-behind" from other modules without fully qualifying the reference. This will lead to coupling of the sheet and the code in other modules/sheets.
• Modules can be exported and imported into other workbooks, and put under version control
• Code in split logically into modules (data access, utilities, spreadsheet formatting etc.) can be reused as units, and are easier to manage if your macros get large.

Since the tooling is so poor in primitive systems such as Excel VBA, best practices, obsessive code hygiene and religious following of conventions are important, especially if you're trying to do anything remotely complex with it.

This article explains the intended usages of different types of code containers. It doesn't qualify why these distinctions should be made, but I believe most developers trying to develop serious applications on the Excel platform follow them.

There's also a list of VBA coding conventions I've found helpful, although they're not directly related to Excel VBA. Please ignore the crazy naming conventions they have on that site, it's all crazy hungarian.

Not quite - since each "left" row in a left-outer-join will match 0-n "right" rows (in the second table), where-as yours matches only 0-1. To do a left outer join, you need SelectMany and DefaultIfEmpty, for example:

var query = from c in db.Customers
            join o in db.Orders
               on c.CustomerID equals o.CustomerID into sr
            from x in sr.DefaultIfEmpty()
            select new {
               CustomerID = c.CustomerID, ContactName = c.ContactName,
               OrderID = x == null ? -1 : x.OrderID };   

(or via the extension methods)

From JPA 2.1 , JPA supports to call stored procedures using the dynamic StoredProcedureQuery, and the declarative @NamedStoredProcedureQuery.

I often do a quick "last week" check as well and the following tends to work well for me and includes today.

DECLARE @StartDate DATETIME 
DECLARE @EndDate DATETIME 

SET @StartDate = Getdate() - 7 /* Seven Days Earlier */
SET @EndDate = Getdate() /* Now */

SELECT id 
FROM   mytable 
WHERE  date BETWEEN @StartDate AND @Enddate 

If you want this to NOT include today just subtract an extra day from the @EndDate. If I select these two variables today get

@StartDate 2015-11-16 16:34:05.347 /* Last Monday */

@EndDate 2015-11-23 16:34:05.347 /* This Monday */

If I wanted Sunday to Sunday I would have the following.

SET @StartDate = Getdate() - 8 /* Eight Days Earlier */
SET @EndDate = Getdate() - 1  /* Yesterday */

@StartDate 2015-11-15 16:34:05.347 /* Previous Sunday */

@EndDate 2015-11-22 16:34:05.347 /* Last Sunday */

I've not seen this solution presented yet; this is my preference for its simpler readability:

select dateadd(month,-1,format(getutcdate(),'yyyy-MM-01'))

Maybe the following extract from the Chapter 23 - Using the Criteria API to Create Queries of the Java EE 6 tutorial will throw some light (actually, I suggest reading the whole Chapter 23):

Querying Relationships Using Joins

For queries that navigate to related entity classes, the query must define a join to the related entity by calling one of the From.join methods on the query root object, or another join object. The join methods are similar to the JOIN keyword in JPQL.

The target of the join uses the Metamodel class of type EntityType<T> to specify the persistent field or property of the joined entity.

The join methods return an object of type Join<X, Y>, where X is the source entity and Y is the target of the join.

Example 23-10 Joining a Query

CriteriaQuery<Pet> cq = cb.createQuery(Pet.class);
Metamodel m = em.getMetamodel();
EntityType<Pet> Pet_ = m.entity(Pet.class);

Root<Pet> pet = cq.from(Pet.class);
Join<Pet, Owner> owner = pet.join(Pet_.owners);

Joins can be chained together to navigate to related entities of the target entity without having to create a Join<X, Y> instance for each join.

Example 23-11 Chaining Joins Together in a Query

CriteriaQuery<Pet> cq = cb.createQuery(Pet.class);
Metamodel m = em.getMetamodel();
EntityType<Pet> Pet_ = m.entity(Pet.class);
EntityType<Owner> Owner_ = m.entity(Owner.class);

Root<Pet> pet = cq.from(Pet.class);
Join<Owner, Address> address = cq.join(Pet_.owners).join(Owner_.addresses);

That being said, I have some additional remarks:

First, the following line in your code:

Root entity_ = cq.from(this.baseClass);

Makes me think that you somehow missed the Static Metamodel Classes part. Metamodel classes such as Pet_ in the quoted example are used to describe the meta information of a persistent class. They are typically generated using an annotation processor (canonical metamodel classes) or can be written by the developer (non-canonical metamodel). But your syntax looks weird, I think you are trying to mimic something that you missed.

Second, I really think you should forget this assay_id foreign key, you're on the wrong path here. You really need to start to think object and association, not tables and columns.

Third, I'm not really sure to understand what you mean exactly by adding a JOIN clause as generical as possible and what your object model looks like, since you didn't provide it (see previous point). It's thus just impossible to answer your question more precisely.

To sum up, I think you need to read a bit more about JPA 2.0 Criteria and Metamodel API and I warmly recommend the resources below as a starting point.

        for word in bad_words:
            if word in line:
                clean = False
        if clean == True:
            cleanfile.write(line)

Or to do the same for all files in a directory:

import os

bad_words = ['abc', 'def', 'ghi', 'jkl']

for root, dirs, files in os.walk(".", topdown = True):
    for file in files:
        if '.txt' in file:
            with open(file) as filename, open('clean '+file, 'w') as cleanfile:
                for line in filename:
                    clean = True
                    for word in bad_words:
                        if word in line:
                            clean = False
                    if clean == True:
                        cleanfile.write(line)

I'm sure there must be a more elegant way to do it, but this did what I wanted it to.

Your code was fine except for the Base 64 encoding bit (which you mentioned was a test), the reason the output may not have made sense is that you were displaying a raw byte array (doing toString() on a byte array returns its internal Java reference, not the String representation of the contents). Here's a version that's just a teeny bit cleaned up and which prints "kyle boon" as the decoded string:

import java.security.MessageDigest;
import java.util.Arrays;

import javax.crypto.Cipher;
import javax.crypto.SecretKey;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;

public class TripleDESTest {

    public static void main(String[] args) throws Exception {

        String text = "kyle boon";

        byte[] codedtext = new TripleDESTest().encrypt(text);
        String decodedtext = new TripleDESTest().decrypt(codedtext);

        System.out.println(codedtext); // this is a byte array, you'll just see a reference to an array
        System.out.println(decodedtext); // This correctly shows "kyle boon"
    }

    public byte[] encrypt(String message) throws Exception {
        final MessageDigest md = MessageDigest.getInstance("md5");
        final byte[] digestOfPassword = md.digest("HG58YZ3CR9"
                .getBytes("utf-8"));
        final byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);
        for (int j = 0, k = 16; j < 8;) {
            keyBytes[k++] = keyBytes[j++];
        }

        final SecretKey key = new SecretKeySpec(keyBytes, "DESede");
        final IvParameterSpec iv = new IvParameterSpec(new byte[8]);
        final Cipher cipher = Cipher.getInstance("DESede/CBC/PKCS5Padding");
        cipher.init(Cipher.ENCRYPT_MODE, key, iv);

        final byte[] plainTextBytes = message.getBytes("utf-8");
        final byte[] cipherText = cipher.doFinal(plainTextBytes);
        // final String encodedCipherText = new sun.misc.BASE64Encoder()
        // .encode(cipherText);

        return cipherText;
    }

    public String decrypt(byte[] message) throws Exception {
        final MessageDigest md = MessageDigest.getInstance("md5");
        final byte[] digestOfPassword = md.digest("HG58YZ3CR9"
                .getBytes("utf-8"));
        final byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);
        for (int j = 0, k = 16; j < 8;) {
            keyBytes[k++] = keyBytes[j++];
        }

        final SecretKey key = new SecretKeySpec(keyBytes, "DESede");
        final IvParameterSpec iv = new IvParameterSpec(new byte[8]);
        final Cipher decipher = Cipher.getInstance("DESede/CBC/PKCS5Padding");
        decipher.init(Cipher.DECRYPT_MODE, key, iv);

        // final byte[] encData = new
        // sun.misc.BASE64Decoder().decodeBuffer(message);
        final byte[] plainText = decipher.doFinal(message);

        return new String(plainText, "UTF-8");
    }
}

types is optional

Simplest answer is:

Step 1: Fire up Terminal.app

Step 2: Type nano .bash_profile – This command will open the .bash_profile document (or create it if it doesn’t already exist) in the easiest to use text editor in Terminal – Nano.

Step 3: Now you can make a simple change to the file. Paste these lines of code to change your Terminal prompt.

export PS1="___________________ | \w @ \h (\u) \n| => "

export PS2="| => "

Step 4: Now save your changes by typing ctrl +o Hit return to save. Then exit Nano by typing ctrl+x

Step 5: Now we need to *activate your changes. Type source .bash_profile and watch your prompt change.

That's it! Enjoy!

You can send intent MASTER_CLEAR in adb:

adb shell am broadcast -a android.intent.action.MASTER_CLEAR

or as root

adb shell  "su -c 'am broadcast -a android.intent.action.MASTER_CLEAR'"

From the performance point of view your solution is not optimal. Every time you add another log entry with +=, the whole string is copied to another place in memory. I would recommend using StringBuilder instead:

StringBuilder sb = new StringBuilder();
...
sb.Append("log something");

...
// flush every 20 seconds as you do it
File.AppendAllText(filePath+"log.txt", sb.ToString());
sb.Clear();

By the way your timer event is probably executed on another thread. So you may want to use a mutex when accessing your sb object.

Another thing to consider is what happens to the log entries that were added within the last 20 seconds of the execution. You probably want to flush your string to the file right before the app exits.

Example of using PHP to get a value from a form:

Put this in foobar.php:

<html>
<body>
  <form action="foobar_submit.php" method="post">
    <input name="my_html_input_tag"  value="PILLS HERE"/>

    <input type="submit" name="my_form_submit_button" 
           value="Click here for penguins"/>

    </form>
</body>
</html>

Read the above code so you understand what it is doing:

"foobar.php is an HTML document containing an HTML form. When the user presses the submit button inside the form, the form's action property is run: foobar_submit.php. The form will be submitted as a POST request. Inside the form is an input tag with the name "my_html_input_tag". It's default value is "PILLS HERE". That causes a text box to appear with text: 'PILLS HERE' on the browser. To the right is a submit button, when you click it, the browser url changes to foobar_submit.php and the below code is run.

Put this code in foobar_submit.php in the same directory as foobar.php:

<?php
  echo $_POST['my_html_input_tag'];
  echo "<br><br>";
  print_r($_POST); 
?>

Read the above code so you know what its doing:

The HTML form from above populated the $_POST superglobal with key/value pairs representing the html elements inside the form. The echo prints out the value by key: 'my_html_input_tag'. If the key is found, which it is, its value is returned: "PILLS HERE".

Then print_r prints out all the keys and values from $_POST so you can peek as to what else is in there.

The value of the input tag with name=my_html_input_tag was put into the $_POST and you retrieved it inside another PHP file.

Margin="1,2,3,4"

1. Left,
2. Top,
3. Right,
4. Bottom

It is also possible to specify just two sizes like this:

Margin="1,2"

1. Left AND right
2. Top AND bottom

Finally you can specify a single size:

Margin="1"

1. used for all sides

The order is the same as in WinForms.

Introduction to Algorithms by Cormen et. al. is a standard introductory algorithms book, and is used by many universities, including my own. It has pretty good coverage and is very approachable.

And anything by Robert Sedgewick is good too.

Also it may cause some warnigs in logs like a Cglib2AopProxy Unable to proxy method. And many other reasons for this are described here Why always have single implementaion interfaces in service and dao layers?

I had the same issue. The unit test template of Visual Studio 2015 (Update 3) generates a class with TestContext property defined as follow:

    private TestContext testContextInstance;

    /// <summary>
    ///Gets or sets the test context which provides
    ///information about and functionality for the current test run.
    ///</summary>
    public TestContext TestContext
    {
        get
        {
            return testContextInstance;
        }
        set
        {
            testContextInstance = value;
        }
    }

After changing it to a public field (ungly) the test runner could discover the test.

public TestContext TestContext;

Very strange behaviour, but it was the cause of the issue in my case.

There is a gmail API now, which lets you send email, read email and create drafts via REST. Unlike the SMTP calls, it is non-blocking which can be a good thing for thread-based webservers sending email in the request thread (like python webservers). The API is also quite powerful.

• Of course, email should be handed off to a non-webserver queue, but it's nice to have options.

It's easiest to setup if you have Google Apps administrator rights on the domain, because then you can give blanket permission to your client. Otherwise you have to fiddle with OAuth authentication and permission.

Here is a gist demonstrating it:

https://gist.github.com/timrichardson/1154e29174926e462b7a

Good try! I think you just have to make a few small changes:

• Escape the square brackets ([ and ]) inside the character class (which are also indicated by [ and ])
• Escape the escape character (\) itself
• Plus there's a quirk where - is special: if it's between two characters, it means a range, but if it's at the beginning or the end, it means the literal - character.

You'll want something like this:

preg_replace('/[^a-zA-Z0-9_%\[().\]\\/-]/s', '', $String);

See http://docs.activestate.com/activeperl/5.10/lib/pods/perlrecharclass.html#special_characters_inside_a_bracketed_character_class if you want to read up further on this topic.

So what's the problem,

It's a ’ (RIGHT SINGLE QUOTATION MARK - U+2019) character which is being decoded as CP-1252 instead of UTF-8. If you check the encodings table, then you see that this character is in UTF-8 composed of bytes 0xE2, 0x80 and 0x99. If you check the CP-1252 code page layout, then you'll see that each of those bytes stand for the individual characters â, € and ™.

and how can I fix it?

Use UTF-8 instead of CP-1252 to read, write, store, and display the characters.

I have the Content-Type set to UTF-8 in both my <head> tag and my HTTP headers:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

This only instructs the client which encoding to use to interpret and display the characters. This doesn't instruct your own program which encoding to use to read, write, store, and display the characters in. The exact answer depends on the server side platform / database / programming language used. Do note that the one set in HTTP response header has precedence over the HTML meta tag. The HTML meta tag would only be used when the page is opened from local disk file system instead of from HTTP.

In addition, my browser is set to Unicode (UTF-8):

This only forces the client which encoding to use to interpret and display the characters. But the actual problem is that you're already sending ’ (encoded in UTF-8) to the client instead of ’. The client is correctly displaying ’ using the UTF-8 encoding. If the client was misinstructed to use, for example ISO-8859-1, you would likely have seen ââ¬â¢ instead.

I am using ASP.NET 2.0 with a database.

This is most likely where your problem lies. You need to verify with an independent database tool what the data looks like.

If the ’ character is there, then you aren't connecting to the database correctly. You need to tell the database connector to use UTF-8.

If your database contains ’, then it's your database that's messed up. Most probably the tables aren't configured to use UTF-8. Instead, they use the database's default encoding, which varies depending on the configuration. If this is your issue, then usually just altering the table to use UTF-8 is sufficient. If your database doesn't support that, you'll need to recreate the tables. It is good practice to set the encoding of the table when you create it.

You're most likely using SQL Server, but here is some MySQL code (copied from this article):

CREATE DATABASE db_name CHARACTER SET utf8;
CREATE TABLE tbl_name (...) CHARACTER SET utf8;

If your table is however already UTF-8, then you need to take a step back. Who or what put the data there. That's where the problem is. One example would be HTML form submitted values which are incorrectly encoded/decoded.

As of Python 3.8 (2018, https://docs.python.org/dev/whatsnew/3.8.html), the recommended method is still:

class CustomExceptionName(Exception):
    """Exception raised when very uncommon things happen"""
    pass

Please don't forget to document, why a custom exception is neccessary!

If you need to, this is the way to go for exceptions with more data:

class CustomExceptionName(Exception):
    """Still an exception raised when uncommon things happen"""
    def __init__(self, message, payload=None):
        self.message = message
        self.payload = payload # you could add more args
    def __str__(self):
        return str(self.message) # __str__() obviously expects a string to be returned, so make sure not to send any other data types

and fetch them like:

try:
    raise CustomExceptionName("Very bad mistake.", "Forgot upgrading from Python 1")
except CustomExceptionName as error:
    print(str(error)) # Very bad mistake
    print("Detail: {}".format(error.payload)) # Detail: Forgot upgrading from Python 1

payload=None is important to make it pickle-able. Before dumping it, you have to call error.__reduce__(). Loading will work as expected.

You maybe should investigate in finding a solution using pythons return statement if you need much data to be transferred to some outer structure. This seems to be clearer/more pythonic to me. Advanced exceptions are heavily used in Java, which can sometimes be annoying, when using a framework and having to catch all possible errors.
