It specifies the size of the log file to trigger rotation. For example size 50M will trigger a log rotation once the file is 50MB or greater in size. You can use the suffix M for megabytes, k for kilobytes, and G for gigabytes. If no suffix is used, it will take it to mean bytes. You can check the example at the end. There are three directives available size, maxsize, and minsize. According to manpage:

minsize size
              Log  files  are  rotated when they grow bigger than size bytes,
              but not before the additionally specified time interval (daily,
              weekly,  monthly, or yearly).  The related size option is simi-
              lar except that it is mutually exclusive with the time interval
              options,  and  it causes log files to be rotated without regard
              for the last rotation time.  When minsize  is  used,  both  the
              size and timestamp of a log file are considered.

size size
              Log files are rotated only if they grow bigger then size bytes.
              If size is followed by k, the size is assumed to  be  in  kilo-
              bytes.  If the M is used, the size is in megabytes, and if G is
              used, the size is in gigabytes. So size 100,  size  100k,  size
              100M and size 100G are all valid.
maxsize size
              Log files are rotated when they grow bigger than size bytes even before
              the additionally specified time interval (daily, weekly, monthly, 
              or yearly).  The related size option is  similar  except  that  it 
              is mutually exclusive with the time interval options, and it causes
              log files to be rotated without regard for the last rotation time.  
              When maxsize is used, both the size and timestamp of a log file are                  
              considered.

Here is an example:

"/var/log/httpd/access.log" /var/log/httpd/error.log {
           rotate 5
           mail [email protected]
           size 100k
           sharedscripts
           postrotate
               /usr/bin/killall -HUP httpd
           endscript
       }

Here is an explanation for both files /var/log/httpd/access.log and /var/log/httpd/error.log. They are rotated whenever it grows over 100k in size, and the old logs files are mailed (uncompressed) to [email protected] after going through 5 rotations, rather than being removed. The sharedscripts means that the postrotate script will only be run once (after the old logs have been compressed), not once for each log which is rotated. Note that the double quotes around the first filename at the beginning of this section allows logrotate to rotate logs with spaces in the name. Normal shell quoting rules apply, with ,, and \ characters supported.

Edit /var/lib/logrotate.status (or /var/lib/loglogrotate/logrotate.status) to reset the 'last rotated' date on the log file you want to test.

Then run logrotate YOUR_CONFIG_FILE.

Or you can use the --force flag, but editing logrotate.status gives you more precision over what does and doesn't get rotated.

Just did this and UrlSearchParams did the trick Here is my code if it helps someone

import 'url-search-params-polyfill';
const userLogsInOptions = (username, password) => {



// const formData = new FormData();
  const formData = new URLSearchParams();
  formData.append('grant_type', 'password');
  formData.append('client_id', 'entrance-app');
  formData.append('username', username);
  formData.append('password', password);
  return (
    {
      method: 'POST',
      headers: {
        // "Content-Type": "application/json; charset=utf-8",
        "Content-Type": "application/x-www-form-urlencoded",
    },
      body: formData.toString(),
    json: true,
  }
  );
};


const getUserUnlockToken = async (username, password) => {
  const userLoginUri = `${scheme}://${host}/auth/realms/${realm}/protocol/openid-connect/token`;
  const response = await fetch(
    userLoginUri,
    userLogsInOptions(username, password),

  const responseJson = await response.json();
  console.log('acces_token ', responseJson.access_token);

You have two way for your question :

1- Use Update Command in your Trigger.

ALTER TRIGGER [dbo].[tr_SCHEDULE_Modified]
   ON [dbo].[SCHEDULE]
   AFTER UPDATE
AS BEGIN
    SET NOCOUNT ON;
    IF UPDATE (QtyToRepair) 
    BEGIN
        UPDATE SCHEDULE 
        SET modified = GETDATE()
           , ModifiedUser = SUSER_NAME()
           , ModifiedHost = HOST_NAME()
        FROM SCHEDULE S INNER JOIN Inserted I 
        ON S.OrderNo = I.OrderNo and S.PartNumber = I.PartNumber
        WHERE S.QtyToRepair <> I.QtyToRepair
    END 
END

2- Use Join between Inserted table and deleted table

ALTER TRIGGER [dbo].[tr_SCHEDULE_Modified]
   ON [dbo].[SCHEDULE]
   AFTER UPDATE
AS BEGIN
    SET NOCOUNT ON;    

    UPDATE SCHEDULE 
    SET modified = GETDATE()
       , ModifiedUser = SUSER_NAME()
       , ModifiedHost = HOST_NAME()
    FROM SCHEDULE S 
    INNER JOIN Inserted I ON S.OrderNo = I.OrderNo and S.PartNumber = I.PartNumber
    INNER JOIN Deleted D ON S.OrderNo = D.OrderNo and S.PartNumber = D.PartNumber                  
    WHERE S.QtyToRepair <> I.QtyToRepair
    AND D.QtyToRepair <> I.QtyToRepair
END

When you use update command for table SCHEDULE and Set QtyToRepair Column to new value, if new value equal to old value in one or multi row, solution 1 update all updated row in Schedule table but solution 2 update only schedule rows that old value not equal to new value.

Yes, on the server side $_SERVER['DOCUMENT_ROOT'] is equivalent to / on the client side.

For example: the value of "{$_SERVER['DOCUMENT_ROOT']}/images/thumbnail.png" will be the string /var/www/html/images/thumbnail.png on a server where it's local file at that path can be reached from the client side at the url http://example.com/images/thumbnail.png

No, in other words the value of $_SERVER['DOCUMENT_ROOT'] is not / rather it is the server's local path to what the server shows the client at example.com/

note: $_SERVER['DOCUMENT_ROOT'] does not include a trailing /

So, let's say you have this table:

CREATE TABLE YourTable(Col1 VARCHAR(10))

And you want to change Col1 to VARCHAR(20). What you need to do is this:

ALTER TABLE YourTable
ALTER COLUMN Col1 VARCHAR(20)

That'll work without problems since the length of the column got bigger. If you wanted to change it to VARCHAR(5), then you'll first gonna need to make sure that there are not values with more chars on your column, otherwise that ALTER TABLE will fail.

A dict's keys are stored in a hashtable so that is their 'natural order', i.e. psuedo-random. Any other ordering is a concept of the consumer of the dict.

sorted() always returns a list, not a dict. If you pass it a dict.items() (which produces a list of tuples), it will return a list of tuples [(k1,v1), (k2,v2), ...] which can be used in a loop in a way very much like a dict, but it is not in anyway a dict!

foo = {
    'a':    1,
    'b':    2,
    'c':    3,
    }

print foo
>>> {'a': 1, 'c': 3, 'b': 2}

print foo.items()
>>> [('a', 1), ('c', 3), ('b', 2)]

print sorted(foo.items())
>>> [('a', 1), ('b', 2), ('c', 3)]

The following feels like a dict in a loop, but it's not, it's a list of tuples being unpacked into k,v:

for k,v in sorted(foo.items()):
    print k, v

Roughly equivalent to:

for k in sorted(foo.keys()):
    print k, foo[k]

In some cases, it might be a bad idea to first add the column to the DataGridView and then hide it.

I for example have a class that has an NHibernate proxy for an Image property for company logos. If I accessed that property (e.g. by calling its ToString method to show that in a DataGridView), it would download the image from the SQL server. If I had a list of Company objects and used that as the dataSource of the DataGridView like that, then (I suspect) it would download ALL the logos BEFORE I could hide the column.

To prevent this, I used the custom attribute

 [System.ComponentModel.Browsable(false)]

on the image property, so that the DataGridView ignores the property (doesn't create the column and doesn't call the ToString methods).

 public class Company
 {
     ...
     [System.ComponentModel.Browsable(false)]
     virtual public MyImageClass Logo { get; set;}

You can simply map nginx's root folder to the location of your website:

nano /etc/nginx/sites-enabled/default

inside the default file, look for the root in the server tag and change your website's default folder, e.g. my websites are at /var/www

server {
        listen 80 default_server;
        listen [::]:80 default_server ipv6only=on;

        root /var/www; <-- Here!
...

When I was evaluating nginx, apache2 and lighttpd, I mapped all of them to my website sitting at /var/www. I found this the best way to evaluate efficiently.

Then you can start/stop the server of your choice and see which performs best.

e.g.

service apache2 stop
service nginx start

Btw, nginx actually is very fast!

For those like me who struggled to get @Sunny Shah accepted answer to work on iPads. You need to set the "Requires full screen" checkbox on in the project settings. Note that this will prevent your app from working on multitasking mode which may or not be acceptable.

No, how you are doing it is correct.

http://www.w3.org/MarkUp/html-spec/html-spec_8.html#SEC8.2.2

its super easy.

You'll need each machine to have it's own copy of ElasticSearch (simply copy the one you have now) -- the reason is that each machine / node whatever is going to keep it's own files that are sharded accross the cluster.

The only thing you really need to do is edit the config file to include the name of the cluster.

If all machines have the same cluster name elasticsearch will do the rest automatically (as long as the machines are all on the same network)

Read here to get you started: https://www.elastic.co/guide/en/elasticsearch/guide/current/deploy.html

When you create indexes (where the data goes) you define at that time how many replicas you want (they'll be distributed around the cluster)

1. ./gradlew clean

   Uses your project's gradle wrapper to execute your project's clean task. Usually, this just means the deletion of the build directory.

2. ./gradlew clean assembleDebug

   Again, uses your project's gradle wrapper to execute the clean and assembleDebug tasks, respectively. So, it will clean first, then execute assembleDebug, after any non-up-to-date dependent tasks.

3. ./gradlew clean :assembleDebug

   Is essentially the same as #2. The colon represents the task path. Task paths are essential in gradle multi-project's, not so much in this context. It means run the root project's assembleDebug task. Here, the root project is the only project.

4. Android Studio --> Build --> Clean

   Is essentially the same as ./gradlew clean. See here.

For more info, I suggest taking the time to read through the Android docs, especially this one.

I also faced similar problem while working on Affable Bean e-commerce site development. I received an error:

If you are on .NET Core, .NET Standard >= 2.1, or depend on the System.Memory package, you can also use the Span<T>.Fill() method:

var valueToFill = 165;
var data = new int[100];

data.AsSpan().Fill(valueToFill);

// print array content
for (int i = 0; i < data.Length; i++)
{
    Console.WriteLine(data[i]);
}

        <Grid>

Building on @boulder_ruby's answer, this is what I'm looking for, assuming us_eco contains the CSV table as from my gist.

CSV.open('outfile.txt','wb', col_sep: "\t") do |csvfile|
  csvfile << us_eco.first.keys
  us_eco.each do |row|
    csvfile << row.values
  end
end

Updated the gist at https://gist.github.com/tamouse/4647196

To insert a VARCHAR2 into a BLOB column you can rely on the function utl_raw.cast_to_raw as next:

insert into mytable(id, myblob) values (1, utl_raw.cast_to_raw('some magic here'));

It will cast your input VARCHAR2 into RAW datatype without modifying its content, then it will insert the result into your BLOB column.

More details about the function utl_raw.cast_to_raw

no, the difference between + and \; should be reversed. + appends the files to the end of the exec command then runs the exec command and \; runs the command for each file.

The problem is find . -type f -iname '*.cpp' -exec mv {} ./test/ \+ should be find . -type f -iname '*.cpp' -exec mv {} ./test/ + no need to escape it or terminate the +

xargs I haven't used in a long time but I think works like +.

You might like IntervalHeap from the C5 Generic Collection Library. To quote the user guide

Class IntervalHeap<T> implements interface IPriorityQueue<T> using an interval heap stored as an array of pairs. The FindMin and FindMax operations, and the indexer’s get-accessor, take time O(1). The DeleteMin, DeleteMax, Add and Update operations, and the indexer’s set-accessor, take time O(log n). In contrast to an ordinary priority queue, an interval heap offers both minimum and maximum operations with the same efficiency.

The API is simple enough

> var heap = new C5.IntervalHeap<int>();
> heap.Add(10);
> heap.Add(5);
> heap.FindMin();
5

Merge commits: retains all of the commits in your branch and interleaves them with commits on the base branch

Merge Squash: retains the changes but omits the individual commits from history

Rebase: This moves the entire feature branch to begin on the tip of the master branch, effectively incorporating all of the new commits in master

If you want to extract just a simple piece of information, you can get that using git show with the --format=<string> option...and ask it not to give you the diff with --no-patch. This means you can get a printf-style output of whatever you want, which might often be a single field.

For instance, to get just the shortened hash (%h) you could say:

$ git show --format="%h" --no-patch
4b703eb

If you're looking to save that into an environment variable in bash (a likely thing for people to want to do) you can use the $() syntax:

$ GIT_COMMIT="$(git show --format="%h" --no-patch)"

$ echo $GIT_COMMIT
4b703eb

The full list of what you can do is in git show --help. But here's an abbreviated list of properties that might be useful:

• %H commit hash
• %h abbreviated commit hash
• %T tree hash
• %t abbreviated tree hash
• %P parent hashes
• %p abbreviated parent hashes
• %an author name
• %ae author email
• %at author date, UNIX timestamp
• %aI author date, strict ISO 8601 format
• %cn committer name
• %ce committer email
• %ct committer date, UNIX timestamp
• %cI committer date, strict ISO 8601 format
• %s subject
• %f sanitized subject line, suitable for a filename
• %gD reflog selector, e.g., refs/stash@{1}
• %gd shortened reflog selector, e.g., stash@{1}

You can find them in /var/log within your root Magento installation

Here are the high-level differences:

Forking

Pros

• Keeps branches separated by user
• Reduces clutter in the primary repository
• Your team process reflects the external contributor process

Cons

• Makes it more difficult to see all of the branches that are active (or inactive, for that matter)
• Collaborating on a branch is trickier (the fork owner needs to add the person as a collaborator)
• You need to understand the concept of multiple remotes in Git
  • Requires additional mental bookkeeping
  • This will make the workflow more difficult for people who aren't super comfortable with Git

Branching

Pros

• Keeps all of the work being done around a project in one place
• All collaborators can push to the same branch to collaborate on it
• There's only one Git remote to deal with

Cons

• Branches that get abandoned can pile up more easily
• Your team contribution process doesn't match the external contributor process
• You need to add team members as contributors before they can branch

If above function is called from many places and you are sure first 2 parameters are passed from every where but not sure about 3rd parameter then you can use window.

window.param3 will handle if it is not defined from the caller method.

The original poster is quoting a GCC compiler error message, but even by reading this thread, it's not clear that the error message is properly addressed - except by @pmg's answer. (+1, btw)

error: void value not ignored as it ought to be

This is a GCC error message that means the return-value of a function is 'void', but that you are trying to assign it to a non-void variable.

Example:

void myFunction()
{
   //...stuff...
}

int main()
{
   int myInt = myFunction(); //Compile error!

    return 0;
}

You aren't allowed to assign void to integers, or any other type.

In the OP's situation:

int a = srand(time(NULL));

...is not allowed. srand(), according to the documentation, returns void.

This question is a duplicate of:

• error: void value not ignored as it ought to be
• "void value not ignored as it ought to be" - Qt/C++
• GCC C compile error, void value not ignored as it ought to be

I am responding, despite it being duplicates, because this is the top result on Google for this error message. Because this thread is the top result, it's important that this thread gives a succinct, clear, and easily findable result.

Here is a link from developer.nokia.com wiki pages, which explains how to install Windows Phone 8 SDK on a Virtual Machine with Working Emulator

And another link here

AFAIK, it is not possible to directly install WP8 SDK in Windows 7, because WP8 sdk is VS 2012 supported and also its emulator works on a Hyper-V (which is integrated into the Windows 8).

If you run the mount command with no command-line arguments, which displays the file systems mounted on your system, you’ll notice a line that looks something like this: none on /dev/pts type devpts (rw,gid=5,mode=620) This indicates that a special type of file system, devpts , is mounted at /dev/pts .This file system, which isn’t associated with any hardware device, is a “magic” file system that is created by the Linux kernel. It’s similar to the /proc file system

Like the /dev directory, /dev/pts contains entries corresponding to devices. But unlike /dev , which is an ordinary directory, /dev/pts is a special directory that is cre- ated dynamically by the Linux kernel.The contents of the directory vary with time and reflect the state of the running system. The entries in /dev/pts correspond to pseudo-terminals (or pseudo-TTYs, or PTYs).

Linux creates a PTY for every new terminal window you open and displays a corre- sponding entry in /dev/pts .The PTY device acts like a terminal device—it accepts input from the keyboard and displays text output from the programs that run in it. PTYs are numbered, and the PTY number is the name of the corresponding entry in /dev/pts .

For example, if the new terminal window’s PTY number is 7, invoke this command from another window: % echo ‘I am a virtual di ’ > /dev/pts/7 The output appears in the new terminal window.

I'm afraid there is not such a function. You'll need a macro to acomplish this task.

You could do something like this in column E(remember to set custom format "dd/mm/yyyy hh:mm"):

=If(B1="";"";Now())

But it will change value everytime file opens.

You'll need save the value via macro.

You can do this by using cors. cors will handle your CORS response

var cors = require('cors')

app.use(cors());

Make sure that this element you would like to control with z-index does not have a parent with z-index property, because element is in a lower stacking context due to its parent’s z-index level.

Here's an example:

<section class="content">            
    <div class="modal"></div>
</section>

<div class="side-tab"></div>

// CSS //
.content {
    position: relative;
    z-index: 1;
}

.modal {
    position: fixed;
    z-index: 100;
}

.side-tab {
    position: fixed;
    z-index: 5;
}

In the example above, the modal has a higher z-index than the content, although the content will appear on top of the modal because "content" is the parent with a z-index property.

Here's an article that explains 4 reasons why z-index might not work: https://coder-coder.com/z-index-isnt-working/

Run this command in your project folder. Use serve instead of build

If you just want to sniff if a Source exists on the local machine but don't have ability to get authorization to do this, you can finger it through the following example (VB).

This bypasses the security error. You could similarly modify this function to return the LogName for the Source.

Public Shared Function eventLogSourceExists(sSource as String) as Boolean
    Try
        EventLog.LogNameFromSourceName(sSource, ".")
        Return True
    Catch
        Return False
    End Try
End Function

API 29.+ usage AndroidX libraries. If you are using API 29.+, then you cannot remove these. If you want to remove AndroidX, then you need to remove the entire 29.+ API from your SDK:

This will work fine.

We had the same issue, in making a websocket connection to the Load Balancer. The issue is in LB, accepting http connection on port 80 and forwarding the request to node (tomcat app on port 8080). We have changed this to accept tcp (http has been changed as 'tcp') connection on port 80. So the first handshake request is forwarded to Node and a websocket connection is made successfully on some random( as far as i know, may be wrong) port.

below command has been used to test the websocket handshake process.

curl -v -i -N -H "Connection: Upgrade" -H "Upgrade: websocket" -H "Host: localhost" -H "Origin: http://LB URL:80" http://LB URL

• Rebuilt URL to: http:LB URL/
• Trying LB URL...
• TCP_NODELAY set
• Connected to LB URL (LB URL) port 80 (#0)

  GET / HTTP/1.1 Host: localhost User-Agent: curl/7.60.0 Accept: / Connection: Upgrade Upgrade: websocket Origin: http://LB URL:80

• Recv failure: Connection reset by peer
• Closing connection 0 curl: (56) Recv failure: Connection reset by peer

For people using Google Cloud Platform, any error will stop the import process. Personally I encountered two different errors depending on the pg_dump command I issued :

1- The input is a PostgreSQL custom-format dump. Use the pg_restore command-line client to restore this dump to a database.

Occurs when you've tried to dump your DB in a non plain text format. I.e when the command lacks the -Fp or --format=plain parameter. However, if you add it to your command, you may then encounter the following error :

2- SET SET SET SET SET SET CREATE EXTENSION ERROR: must be owner of extension plpgsql

This is a permission issue I have been unable to fix using the command provided in the GCP docs, the tips from this current thread, or following advice from Google Postgres team here. Which recommended to issue the following command :

pg_dump -Fp --no-acl --no-owner -U myusername myDBName > mydump.sql

The only thing that did the trick in my case was manually editing the dump file and commenting out all commands relating to plpgsql.

I hope this helps GCP-reliant souls.

Update :

It's easier to dump the file commenting out extensions, especially since some dumps can be huge : pg_dump ... | grep -v -E '(CREATE\ EXTENSION|COMMENT\ ON)' > mydump.sql

Which can be narrowed down to plpgsql : pg_dump ... | grep -v -E '(CREATE\ EXTENSION\ IF\ NOT\ EXISTS\ plpgsql|COMMENT\ ON\ EXTENSION\ plpgsql)' > mydump.sql

As @joris pointed out, iterrows is much slower than itertuples and itertuples is approximately 100 times fater than iterrows, and I tested speed of both methods in a DataFrame with 5027505 records the result is for iterrows, it is 1200it/s, and itertuples is 120000it/s.

If you use itertuples, note that every element in the for loop is a namedtuple, so to get the value in each column, you can refer to the following example code

>>> df = pd.DataFrame({'col1': [1, 2], 'col2': [0.1, 0.2]},
                      index=['a', 'b'])
>>> df
   col1  col2
a     1   0.1
b     2   0.2
>>> for row in df.itertuples():
...     print(row.col1, row.col2)
...
1, 0.1
2, 0.2

matplotlib.rcParams.update({'font.size': 22})

If the delete is recent enough (Like an Oh-NO! moment) you should still have a message:

Deleted branch <branch name> (was abcdefghi).

you can still run:

git checkout abcdefghi

git checkout -b <some new branch name or the old one>

Essentially, there are three settings that one has to update (Preference >> settings):

• workbench.editor.enablePreview: set this to globally enable or disable preview editors

• workbench.editor.enablePreviewFromQuickOpen: set this to enable or disable preview editors when opened from Quick Open

• workbench.editor.showTabs: finally one will need to set this
  otherwise, there will be no tabs displayed and you will just be
  wondering why setting/unsetting the above two did not work

Use css text-transform to display text in all input type text. In Jquery you can then transform the value to uppercase on blur event.

Css:

input[type=text] {
    text-transform: uppercase;
}

Jquery:

$(document).on('blur', "input[type=text]", function () {
    $(this).val(function (_, val) {
        return val.toUpperCase();
    });
});

Adding to previous solutions, you can also specify the font size relative to the base_size included in themes such as theme_bw() (where base_size is 11) using the rel() function.

For example:

ggplot(mtcars, aes(disp, mpg)) +
  geom_point() +
  theme_bw() +
  theme(axis.text.x=element_text(size=rel(0.5), angle=90))

git log --grep=<pattern>
            Limit the commits output to ones with log message that matches the
            specified pattern (regular expression).

this works for me, so try it :

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

For SQL Server 2008 R2, installing Cumulative Update 7 will fix the problem. The file you need is

SQLServer2008R2_RTM_CU7_2507770_10_50_1777_x86
or
SQLServer2008R2_RTM_CU7_2507770_10_50_1777_x64

I also had to uninstall and re-install SQL Server 2008 first (which didn't fix it, but the CU did).

We want to automatically pick property file based upon mentioned the profile name in spring.profiles.active and the path in -Dspring.config.location

application-dev.properties

If we are running jar in Unix OS then we have to use / at the end of -Dspring.config.location otherwise it will give below error.

Error :: java.lang.IllegalStateException: File extension of config file location 'file:/home/xyz/projectName/cfg' is not known to any PropertySourceLoader. If the location is meant to reference a directory, it must end in '/'

Example

java -Dspring.profiles.active=dev -Dspring.config.location=/home/xyz/projectName/cfg/ -jar /home/xyz/project/abc.jar

or

java -jar /home/xyz/project/abc.jar --spring.profiles.active=dev --spring.config.location=/home/xyz/projectName/cfg/

Try this code it's really working.

    number = Integer.parseInt(YourEditTextName.getText().toString());
} catch(NumberFormatException e) {
   System.out.println("parse value is not valid : " + e);
} 

Use dynamic_cast for converting pointers/references within an inheritance hierarchy.

Use static_cast for ordinary type conversions.

Use reinterpret_cast for low-level reinterpreting of bit patterns. Use with extreme caution.

Use const_cast for casting away const/volatile. Avoid this unless you are stuck using a const-incorrect API.

If you're interested in the reasons for these rules, it's because the time it takes the earth to make exactly one orbit around the sun is a long imprecise decimal value. It's not exactly 365.25. It's slightly less than 365.25, so every 100 years, one leap day must be eliminated (365.25 - 0.01 = 365.24). But that's not exactly correct either. The value is slightly larger than 365.24. So only 3 out of 4 times will the 100 year rule apply (or in other words, add back in 1 day every 400 years; 365.25 - 0.01 + 0.0025 = 365.2425).

The profile choices need to be setup as a ManyToManyField for this to work correctly.

So... your model should be like this:

class Choices(models.Model):
  description = models.CharField(max_length=300)

class Profile(models.Model):
  user = models.ForeignKey(User, blank=True, unique=True, verbose_name='user')
  choices = models.ManyToManyField(Choices)

Then, sync the database and load up Choices with the various options you want available.

Now, the ModelForm will build itself...

class ProfileForm(forms.ModelForm):
  Meta:
    model = Profile
    exclude = ['user']

And finally, the view:

if request.method=='POST':
  form = ProfileForm(request.POST)
  if form.is_valid():
    profile = form.save(commit=False)
    profile.user = request.user
    profile.save()
else:
  form = ProfileForm()

return render_to_response(template_name, {"profile_form": form}, context_instance=RequestContext(request))

It should be mentioned that you could setup a profile in a couple different ways, including inheritance. That said, this should work for you as well.

Good luck.

Most of the LINQ extension methods return results. ForEach does not fit into this pattern as it returns nothing.

If you want the accepted answer to work in JQuery 3 change the code like this:

var scrollItems = menuItems.map(function () {
    var id = $(this).attr("href");
    try {
        var item = $(id);
      if (item.length) {
        return item;
      }
    } catch {}
  });

I also added a try-catch to prevent javascript from crashing if there is no element by that id. Feel free to improve it even more ;)

• Use the fill handle or Ctrl+D to fill it down to the length of Column K's values.
• Select the whole of Column L's values and copy them to the clipboard
• Select the same range in Column K, right-click to select 'Paste Special' and choose 'Values'

Use

Model.created_at.strftime("%FT%T")

where,

%F - The ISO 8601 date format (%Y-%m-%d)
%T - 24-hour time (%H:%M:%S)

Following are some of the frequently used useful list of Date and Time formats that you could specify in strftime method:

Date (Year, Month, Day):
  %Y - Year with century (can be negative, 4 digits at least)
          -0001, 0000, 1995, 2009, 14292, etc.
  %C - year / 100 (round down.  20 in 2009)
  %y - year % 100 (00..99)

  %m - Month of the year, zero-padded (01..12)
          %_m  blank-padded ( 1..12)
          %-m  no-padded (1..12)
  %B - The full month name (``January'')
          %^B  uppercased (``JANUARY'')
  %b - The abbreviated month name (``Jan'')
          %^b  uppercased (``JAN'')
  %h - Equivalent to %b

  %d - Day of the month, zero-padded (01..31)
          %-d  no-padded (1..31)
  %e - Day of the month, blank-padded ( 1..31)

  %j - Day of the year (001..366)

Time (Hour, Minute, Second, Subsecond):
  %H - Hour of the day, 24-hour clock, zero-padded (00..23)
  %k - Hour of the day, 24-hour clock, blank-padded ( 0..23)
  %I - Hour of the day, 12-hour clock, zero-padded (01..12)
  %l - Hour of the day, 12-hour clock, blank-padded ( 1..12)
  %P - Meridian indicator, lowercase (``am'' or ``pm'')
  %p - Meridian indicator, uppercase (``AM'' or ``PM'')

  %M - Minute of the hour (00..59)

  %S - Second of the minute (00..59)

  %L - Millisecond of the second (000..999)
  %N - Fractional seconds digits, default is 9 digits (nanosecond)
          %3N  millisecond (3 digits)
          %6N  microsecond (6 digits)
          %9N  nanosecond (9 digits)
          %12N picosecond (12 digits)

There is not really any other way in JavaScript to concatenate strings.
You could theoretically use .concat(), but that's way slower than just +

Libraries are more often than not slower than native JavaScript, especially on basic operations like string concatenation, or numerical operations.

Simply put: + is the fastest.

This can also happen due to the bad unzipping process of SDK.It Happend to me. Dont use inbuilt windows unzip process. use WINRAR software for unzipping sdk

Swift 4:

I was having an issue with the most accepted answer, in which hiding the keyboard did not return the view all the way to the bottom of the page (only partially). This worked for me (+updated for Swift 4).

How do I run an executable JAR file? If you have a jar file called Example.jar, follow these rules:

Open a notepad.exe.
Write : java -jar Example.jar.
Save it with the extension .bat.
Copy it to the directory which has the .jar file.
Double click it to run your .jar file.

ActionDone is use when click in next button in the keyboard that time keyboard is hide.Use in Edit Text or AppcompatEdit

XML

1.1 If you use AppCompatEdittext

    <android.support.v7.widget.AppCompatEditText
    android:id="@+id/edittext"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:imeOptions="actionDone"/>

1.2 If you use Edittext

    <EditText
    android:id="@+id/edittext"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:imeOptions="actionDone"/>

JAVA

EditText edittext= (EditText) findViewById(R.id.edittext);
edittext.setImeOptions(EditorInfo.IME_ACTION_DONE);

Below is the solution in javascript language using ES6 syntax.

Stack.js

//stack using array
class Stack {
  constructor() {
    this.data = [];
  }

  push(data) {
    this.data.push(data);
  }

  pop() {
    return this.data.pop();
  }

  peek() {
    return this.data[this.data.length - 1];
  }

  size(){
    return this.data.length;
  }
}

export { Stack };

QueueUsingTwoStacks.js

import { Stack } from "./Stack";

class QueueUsingTwoStacks {
  constructor() {
    this.stack1 = new Stack();
    this.stack2 = new Stack();
  }

  enqueue(data) {
    this.stack1.push(data);
  }

  dequeue() {
    //if both stacks are empty, return undefined
    if (this.stack1.size() === 0 && this.stack2.size() === 0)
      return undefined;

    //if stack2 is empty, pop all elements from stack1 to stack2 till stack1 is empty
    if (this.stack2.size() === 0) {
      while (this.stack1.size() !== 0) {
        this.stack2.push(this.stack1.pop());
      }
    }

    //pop and return the element from stack 2
    return this.stack2.pop();
  }
}

export { QueueUsingTwoStacks };

Below is the usage:

index.js

import { StackUsingTwoQueues } from './StackUsingTwoQueues';

let que = new QueueUsingTwoStacks();
que.enqueue("A");
que.enqueue("B");
que.enqueue("C");

console.log(que.dequeue());  //output: "A"

Good to also check the other combinators in the family and to get back to what is this specific one.

• ul li
• ul > li
• ul + ul
• ul ~ ul

Example checklist:

• ul li - Looking inside - Selects all the li elements placed (anywhere) inside the ul; Descendant selector
• ul > li - Looking inside - Selects only the direct li elements of ul; i.e. it will only select direct children li of ul; Child Selector or Child combinator selector
• ul + ul - Looking outside - Selects the ul immediately following the ul; It is not looking inside, but looking outside for the immediately following element; Adjacent Sibling Selector
• ul ~ ul - Looking outside - Selects all the ul which follows the ul doesn't matter where it is, but both ul should be having the same parent; General Sibling Selector

The one we are looking at here is General Sibling Selector

I was wondering, would this be on any use to you?

Do not use regular expressions to parse HTML.

But if you ever need to find all regexp matches in a string, use the findall function.

import re
line = 'bla bla bla<form>Form 1</form> some text...<form>Form 2</form> more text?'
matches = re.findall('<form>(.*?)</form>', line, re.DOTALL)
print(matches)

# Output: ['Form 1', 'Form 2']

No it is not safe. You could later do var IsLoggedIn = "Foo"; and JavaScript will not throw an error.

It is possible to do

var IsLoggedIn = new Boolean(false);
var IsLoggedIn = new Boolean(true);

You can also pass the non boolean variable into the new Boolean() and it will make IsLoggedIn boolean.

var IsLoggedIn = new Boolean(0); // false
var IsLoggedIn = new Boolean(NaN); // false
var IsLoggedIn = new Boolean("Foo"); // true
var IsLoggedIn = new Boolean(1); // true

Yes, according to RFC 3696 apostrophes are valid as long as they come before the @ symbol.

According to the curl man page:

You can specify any amount of URLs on the command line. They will be fetched in a sequential manner in the specified order.

So the simplest and most efficient (curl will send them all down a single TCP connection [those to the same origin]) approach would be put them all on a single invocation of curl e.g.:

curl http://example.com/?update_=1 http://example.com/?update_=2

To create a "drop down menu" you can use OptionMenu in tkinter

Example of a basic OptionMenu:

from Tkinter import *

master = Tk()

variable = StringVar(master)
variable.set("one") # default value

w = OptionMenu(master, variable, "one", "two", "three")
w.pack()

mainloop()

More information (including the script above) can be found here.

Creating an OptionMenu of the months from a list would be as simple as:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

mainloop()

In order to retrieve the value the user has selected you can simply use a .get() on the variable that we assigned to the widget, in the below case this is variable:

from tkinter import *

OPTIONS = [
"Jan",
"Feb",
"Mar"
] #etc

master = Tk()

variable = StringVar(master)
variable.set(OPTIONS[0]) # default value

w = OptionMenu(master, variable, *OPTIONS)
w.pack()

def ok():
    print ("value is:" + variable.get())

button = Button(master, text="OK", command=ok)
button.pack()

mainloop()

I would highly recommend reading through this site for further basic tkinter information as the above examples are modified from that site.

OPcache replaces APC

Because OPcache is designed to replace the APC module, it is not possible to run them in parallel in PHP. This is fine for caching PHP opcode as neither affects how you write code.

However it means that if you are currently using APC to store other data (through the apc_store() function) you will not be able to do that if you decide to use OPCache.

You will need to use another library such as either APCu or Yac which both store data in shared PHP memory, or switch to use something like memcached, which stores data in memory in a separate process to PHP.

Also, OPcache has no equivalent of the upload progress meter present in APC. Instead you should use the Session Upload Progress.

Settings for OPcache

The documentation for OPcache can be found here with all of the configuration options listed here. The recommended settings are:

; Sets how much memory to use
opcache.memory_consumption=128

;Sets how much memory should be used by OPcache for storing internal strings 
;(e.g. classnames and the files they are contained in)
opcache.interned_strings_buffer=8

; The maximum number of files OPcache will cache
opcache.max_accelerated_files=4000

;How often (in seconds) to check file timestamps for changes to the shared
;memory storage allocation.
opcache.revalidate_freq=60

;If enabled, a fast shutdown sequence is used for the accelerated code
;The fast shutdown sequence doesn't free each allocated block, but lets
;the Zend Engine Memory Manager do the work.
opcache.fast_shutdown=1

;Enables the OPcache for the CLI version of PHP.
opcache.enable_cli=1

If you use any library or code that uses code annotations you must enable save comments:

opcache.save_comments=1

If disabled, all PHPDoc comments are dropped from the code to reduce the size of the optimized code. Disabling "Doc Comments" may break some existing applications and frameworks (e.g. Doctrine, ZF2, PHPUnit)

With the inspiration of @Joel Ostblom

For those who already have a workable dictionary for merely aggregation, you can use/modify the following code for the newer version aggregation, separating aggregation and renaming part. Please be aware of the nested dictionary if there are more than 1 item.

def agg_translate_agg_rename(input_agg_dict):
    agg_dict = {}
    rename_dict = {}
    for k, v in input_agg_dict.items():
        if len(v) == 1:
            agg_dict[k] = list(v.values())[0]
            rename_dict[k] = list(v.keys())[0]
        else:
            updated_index = 1
            for nested_dict_k, nested_dict_v in v.items():
                modified_key = k + "_" + str(updated_index)
                agg_dict[modified_key] = nested_dict_v
                rename_dict[modified_key] = nested_dict_k
                updated_index += 1
    return agg_dict, rename_dict

one_dict = {"column1": {"foo": 'sum'}, "column2": {"mean": 'mean', "std": 'std'}}
agg, rename = agg_translator_aa(one_dict)

We get

agg = {'column1': 'sum', 'column2_1': 'mean', 'column2_2': 'std'}
rename = {'column1': 'foo', 'column2_1': 'mean', 'column2_2': 'std'}

Please let me know if there is a smarter way to do it. Thanks.

So I have ElementTree 1.2.6 on my box now, and ran the following code against the XML chunk you posted:

import elementtree.ElementTree as ET

tree = ET.parse("test.xml")
doc = tree.getroot()
thingy = doc.find('timeSeries')

print thingy.attrib

and got the following back:

{'name': 'NWIS Time Series Instantaneous Values'}

It appears to have found the timeSeries element without needing to use numerical indices.

What would be useful now is knowing what you mean when you say "it doesn't work." Since it works for me given the same input, it is unlikely that ElementTree is broken in some obvious way. Update your question with any error messages, backtraces, or anything you can provide to help us help you.

You set the DisplayMemberPath and the SelectedValuePath to "Name", so I assume that you have a class PhoneBookEntry with a public property Name.

Have you set the DataContext to your ConnectionViewModel object?

I copied you code and made some minor modifications, and it seems to work fine. I can set the viewmodels PhoneBookEnty property and the selected item in the combobox changes, and I can change the selected item in the combobox and the view models PhoneBookEntry property is set correctly.

Here is my XAML content:

<Window x:Class="WpfApplication6.Window1"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="Window1" Height="300" Width="300">
<Grid>
    <StackPanel>
        <Button Click="Button_Click">asdf</Button>
        <ComboBox ItemsSource="{Binding Path=PhonebookEntries}"
                  DisplayMemberPath="Name"
                  SelectedValuePath="Name"
                  SelectedValue="{Binding Path=PhonebookEntry}" />
    </StackPanel>
</Grid>
</Window>

And here is my code-behind:

namespace WpfApplication6
{

    /// <summary>
    /// Interaction logic for Window1.xaml
    /// </summary>
    public partial class Window1 : Window
    {
        public Window1()
        {
            InitializeComponent();
            ConnectionViewModel vm = new ConnectionViewModel();
            DataContext = vm;
        }

        private void Button_Click(object sender, RoutedEventArgs e)
        {
            ((ConnectionViewModel)DataContext).PhonebookEntry = "test";
        }
    }

    public class PhoneBookEntry
    {
        public string Name { get; set; }

        public PhoneBookEntry(string name)
        {
            Name = name;
        }

        public override string ToString()
        {
            return Name;
        }
    }

    public class ConnectionViewModel : INotifyPropertyChanged
    {
        public ConnectionViewModel()
        {
            IList<PhoneBookEntry> list = new List<PhoneBookEntry>();
            list.Add(new PhoneBookEntry("test"));
            list.Add(new PhoneBookEntry("test2"));
            _phonebookEntries = new CollectionView(list);
        }

        private readonly CollectionView _phonebookEntries;
        private string _phonebookEntry;

        public CollectionView PhonebookEntries
        {
            get { return _phonebookEntries; }
        }

        public string PhonebookEntry
        {
            get { return _phonebookEntry; }
            set
            {
                if (_phonebookEntry == value) return;
                _phonebookEntry = value;
                OnPropertyChanged("PhonebookEntry");
            }
        }

        private void OnPropertyChanged(string propertyName)
        {
            if (PropertyChanged != null)
                PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
        }
        public event PropertyChangedEventHandler PropertyChanged;
    }
}

Edit: Geoffs second example does not seem to work, which seems a bit odd to me. If I change the PhonebookEntries property on the ConnectionViewModel to be of type ReadOnlyCollection, the TwoWay binding of the SelectedValue property on the combobox works fine.

Maybe there is an issue with the CollectionView? I noticed a warning in the output console:

System.Windows.Data Warning: 50 : Using CollectionView directly is not fully supported. The basic features work, although with some inefficiencies, but advanced features may encounter known bugs. Consider using a derived class to avoid these problems.

Edit2 (.NET 4.5): The content of the DropDownList can be based on ToString() and not of DisplayMemberPath, while DisplayMemberPath specifies the member for the selected and displayed item only.

To understand the difference between a simulator and an emulator, keep in mind that a simulator tries to mimic the behavior of a real device. For example, in the case of the iOS Simulator, it simulates the real behavior of an actual iPhone/iPad device. However, the Simulator itself uses the various libraries installed on the Mac (such as QuickTime) to perform its rendering so that the effect looks the same as an actual iPhone. In addition, applications tested on the Simulator are compiled into x86 code, which is the byte-code understood by the Simulator. A real iPhone device, conversely, uses ARM-based code.

In contrast, an emulator emulates the working of a real device. Applications tested on an emulator are compiled into the actual byte-code used by the real device. The emulator executes the application by translating the byte-code into a form that can be executed by the host computer running the emulator.

To understand the subtle difference between simulation and emulation, imagine you are trying to convince a child that playing with knives is dangerous. To simulate this, you pretend to cut yourself with a knife and groan in pain. To emulate this, you actually cut yourself.

For those who still getting The magic number in GZip header is not correct. Make sure you are passing in a GZip stream. ERROR and if your string was zipped using php you'll need to do something like:

       public static string decodeDecompress(string originalReceivedSrc) {
        byte[] bytes = Convert.FromBase64String(originalReceivedSrc);

        using (var mem = new MemoryStream()) {
            //the trick is here
            mem.Write(new byte[] { 0x1f, 0x8b, 0x08, 0x00, 0x00, 0x00, 0x00, 0x00 }, 0, 8);
            mem.Write(bytes, 0, bytes.Length);

            mem.Position = 0;

            using (var gzip = new GZipStream(mem, CompressionMode.Decompress))
            using (var reader = new StreamReader(gzip)) {
                return reader.ReadToEnd();
                }
            }
        }

In order for Webpack to return the correct asset paths, you need to use require('./relative/path/to/file.jpg'), which will get processed by file-loader and returns the resolved URL.

computed: {
  iconUrl () {
    return require('./assets/img.png')
    // The path could be '../assets/img.png', etc., which depends on where your vue file is
  }
}

This happened to me when I accidentally switched the Build Action of the edmx file (appears under Properties in the IDE) from 'EntityDeploy' to 'None'. EntityDeploy is what populates the metadata for you: see http://msdn.microsoft.com/en-us/library/cc982037.aspx

Maven

The Answer by Bhesh Gurung is correct… unless your NetBeans project is Maven based.

Dependency

Under Maven, you add a "dependency". A dependency is a description of a library (its name & version number) you want to use from your code.

Or a dependency could be a description of a library which another library needs ("depends on"). Maven automatically handles this chain, libraries that need other libraries that then need other libraries and so on. For the mathematical-minded, perhaps the phrase "Maven resolves the transitive dependencies" makes sense.

Repository

Maven gets this related-ness information, and the libraries themselves from a Maven repository. A repository is basically an online database and collection of download files (the dependency library).

Easy to Use

Adding a dependency to a Maven-based project is really quite easy. That is the whole point to Maven, to make managing dependent libraries easy and to make building them into your project easy. To get started with adding a dependency, see this Question, Adding dependencies in Maven Netbeans and my Answer with screenshot.

The reason why you have to modify the AppData could be:

1. Node.js couldn't handle path longer then 256 characters, windows tend to have very long PATH.
2. If you are login from a corporate environment, your AppData might be on the server - that won't work. The npm directory must be in your local drive.

Even after doing that, the latest LTE (4.4.4) still have problem with Windows 10, it worked for a little while then whenever I try to:

$ npm install _some_package_ --global 

Node throw the "FATAL ERROR CALL_AND_RETRY_LAST Allocation failed - process out of memory" error. Still try to find a solution to that problem.

The only thing I find works is to run Vagrant or Virtual box, then run the Linux command line (must matching the path) which is quite a messy solution.

Within a module, Verilog contains essentially two constructs: items and statements. Statements are always found in procedural contexts, which include anything in between begin..end, functions, tasks, always blocks and initial blocks. Items, such as generate constructs, are listed directly in the module. For loops and most variable/constant declarations can exist in both contexts.

In your code, it appears that you want the for loop to be evaluated as a generate item but the loop is actually part of the procedural context of the always block. For a for loop to be treated as a generate loop it must be in the module context. The generate..endgenerate keywords are entirely optional(some tools require them) and have no effect. See this answer for an example of how generate loops are evaluated.

//Compiler sees this
parameter ROWBITS = 4;
reg [ROWBITS-1:0] temp;
genvar c;

    always @(posedge sysclk) //Procedural context starts here
    begin
        for (c = 0; c < ROWBITS; c = c + 1) begin: test
            temp[c] <= 1'b0; //Still a genvar
        end
    end

To fetch a remote PR into your local repo,

git fetch origin pull/$ID/head:$BRANCHNAME

where $ID is the pull request id and $BRANCHNAME is the name of the new branch that you want to create. Once you have created the branch, then simply

git checkout $BRANCHNAME

See the official GitHub documentation for more.

No, there is no way for an webapp to receive push notification. What you could do is to wrap your webapp into a native app which has push notifications.

Correct, use --httpPort parameter. If you also want to specify the $JENKINS_HOME, you can do like this:

java -DJENKINS_HOME=/Users/Heros/jenkins -jar jenkins.war  --httpPort=8484

onCreate() method gets called when activity gets created, and its called only once in whole Activity life cycle. where as onStart() is called when activity is stopped... I mean it has gone to background and its onStop() method is called by the os. onStart() may be called multiple times in Activity life cycle.More details here

This eclipse documentation has details on the markups in .project file: The project description file

It describes the .project file as:

When a project is created in the workspace, a project description file is automatically generated that describes the project. The purpose of this file is to make the project self-describing, so that a project that is zipped up or released to a server can be correctly recreated in another workspace. This file is always called ".project"

Try this in your alice repository (before pushing):

git config push.default tracking

Or, configure it as the default for your user with git config --global ….

git push does default to the origin repository (which is normally the repository from which you cloned the current repository), but it does not default to pushing the current branch—it defaults to pushing only branches that exist in both the source repository and the destination repository.

The push.default configuration variable (see git-config(1)) controls what git push will push when it is not given any “refspec” arguments (i.e. something after a repository name). The default value gives the behavior described above.

Here are possible values for push.default:

• nothing
  This forces you to supply a “refspec”.

• matching (the default)
  This pushes all branches that exist in both the source repository and the destination repository.
  This is completely independent of the branch that is currently checked out.

• upstream or tracking
  (Both values mean the same thing. The later was deprecated to avoid confusion with “remote-tracking” branches. The former was introduced in 1.7.4.2, so you will have to use the latter if you are using Git 1.7.3.1.)
  These push the current branch to the branch specified by its “upstream” configuration.

• current
  This pushes the current branch to the branch of the same name at the destination repository.

  These last two end up being the same for common cases (e.g. working on local master which uses origin/master as its upstream), but they are different when the local branch has a different name from its “upstream” branch:

  git checkout master
  # hack, commit, hack, commit
  
  # bug report comes in, we want a fix on master without the above commits
  
  git checkout -b quickfix origin/master  # "upstream" is master on origin
  # fix, commit
  git push
  

  With push.default equal to upstream (or tracking), the push would go to origin’s master branch. When it is equal to current, the push would go to origin’s quickfix branch.

The matching setting will update bare’s master in your scenario once it has been established. To establish it, you could use git push origin master once.

However, the upstream setting (or maybe current) seems like it might be a better match for what you expect to happen, so you might want to try it:

# try it once (in Git 1.7.2 and later)
git -c push.default=upstream push

# configure it for only this repository
git config push.default upstream

# configure it for all repositories that do not override it themselves
git config --global push.default upstream

(Again, if you are still using a Git before 1.7.4.2, you will need to use tracking instead of upstream).

This was implemented by Facebook by design for security reasons. Here's the explanation from Eric Osgood, a Facebook Team member:

This has been marked as 'by design' because it prevents a potential security vulnerability.

Some browsers will append the hash fragment from a URL to the end of a new URL to which they have been redirected (if that new URL does not itself have a hash fragment).

For example if example1.com returns a redirect to example2.com, then a browser going to example1.com#abc will go to example2.com#abc, and the hash fragment content from example1.com would be accessible to a script on example2.com.

Since it is possible to have one auth flow redirect to another, it would be possible to have sensitive auth data from one app accessible to another.

This is mitigated by appending a new hash fragment to the redirect URL to prevent this browser behavior.

If the aesthetics, or client-side behavior, of the resulting URL are of concern, it would be possible to use window.location.hash (or even a server-side redirect of your own) to remove the offending characters.

A table can have multiple candidate keys. Each candidate key is a column or set of columns that are UNIQUE, taken together, and also NOT NULL. Thus, specifying values for all the columns of any candidate key is enough to determine that there is one row that meets the criteria, or no rows at all.

Candidate keys are a fundamental concept in the relational data model.

It's common practice, if multiple keys are present in one table, to designate one of the candidate keys as the primary key. It's also common practice to cause any foreign keys to the table to reference the primary key, rather than any other candidate key.

I recommend these practices, but there is nothing in the relational model that requires selecting a primary key among the candidate keys.

Try this:

var var1=42;
var var2;

alert(var2 = var1); //show result of assignment expression is assigned value
alert(var2); // show assignment did occur.

Note the single '=' in the first alert. This will show that the result of an assignment expression is the assigned value, and the 2nd alert will show you that assignment did occur.

It follows logically that assignment must have chained from right to left. However, since this is all atomic to the javascript (there's no threading) a particular engine may choose to actually optimize it a little differently.

The :query_string_normalizer option is also available, which will override the default normalizer HashConversions.to_params(query)

query_string_normalizer: ->(query){query.to_json}

I had given an answer in Super User site for the thread "Open a network drive with different user" (https://superuser.com/questions/577113/open-a-network-drive-with-different-user/1524707#1524707)

I want to use a router's USB drive as a network storage for different users, as this thread I met the error message

"Multiple Connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again."

Beside the method using "NET USE" command, I found another way from the webpage

http://backupchain.com/i/how-to-fix-error-1219-multiple-connections-to-a-server-or-shared-resource-by-the-same-user

It is better to solve the Windows connection limitation by editing the hosts file which is under the directory "C:\Windows\System32\Drivers\etc".

For example, my router IP address is 192.168.1.1 and its USB drive has three share folders as \user1, \user2 and \user3 which separated for three users, then we can add the following three lines in hosts file,

192.168.1.1 server1

192.168.1.1 server2

192.168.1.1 server3

in this example we map the server1 to user #1, server2 to user #2 and server3 to user #3.

After reboot the PC, we can connect the folder \user1 for user #1, \user2 for user #2 and \user3 for user #3 simultaneously in Windows File Explorer, that is

if we type the router name as \\server1 in folder indication field of Explorer, it will show all shared folders of router's USB drive in Explorer right pane and sever1 under "Network" item in left pane of Explorer, then the user #1 may access the share folder \user1.

At this time if we type \\server2 or \\server3 in the directory indication field of Explorer, then we may connect the router's USB drive as server2 or server3 and access the share folder \user2 or \user3 for user #2 or user #3 and keep the "server1" connection simultaneously.

Using this method we may also use the "NET USE" command to do these actions.

Try this, at the end of the each loop, ids array will contain all the hexcodes.

var ids = [];

    $(document).ready(function($) {
    var $div = $("<div id='hexCodes'></div>").appendTo(document.body), code;
    $(".color_cell").each(function() {
        code = $(this).attr('id');
        ids.push(code);
        $div.append(code + "<br />");
    });



});

a little plugin for it.

(function($) {
    $.fn.hasScrollBar = function() {
        return this.get(0).scrollHeight > this.height();
    }
})(jQuery);

use it like this,

$('#my_div1').hasScrollBar(); // returns true if there's a `vertical` scrollbar, false otherwise..

tested working on Firefox, Chrome, IE6,7,8

but not working properly on body tag selector

demo

Edit

I found out that when you have horizontal scrollbar that causes vertical scrollbar to appear, this function does not work....

I found out another solution... use clientHeight

return this.get(0).scrollHeight > this.get(0).clientHeight;

For me, I have fixed the problem using android:layout_centerVertical="true" in a parent RelativeLayout:

<RelativeLayout ... >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:layout_centerVertical="true">

</RelativeLayout>

JavaScript runs in the context of the current HTML document, so it won't be able to determine anything about a current user unless it's in the current page or you do AJAX calls to a server-side script to get more information.

JavaScript will not be able to determine your Windows user name.

You can set up a developer application and set the url to localhost.com:port Make sure to map localhost.com to localhost on your hosts file

Works for me

Instead of

Object.values(myObject);

use

Object["values"](myObject);

In your example case:

const values = Object["values"](data).map(x => x.substr(0, x.length - 4));

This will hide the ts compiler error.

What about gethostname()?

Edit: This might not be an option I suppose, depending on your environment. It's new in PHP 5.3. php_uname('n') might work as an alternative.

use the String.Trim() function.

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

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

You have two ways to hide the title bar by hiding it in a specific activity or hiding it on all of the activity in your app.

You can achieve this by create a custom theme in your styles.xml.

<resources>
    <style name="MyTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>
</resources>

If you are using AppCompatActivity, there is a bunch of themes that android provides nowadays. And if you choose a theme that has .NoActionBaror .NoTitleBar. It will disable you action bar for your theme.

After setting up a custom theme, you might want to use the theme in you activity/activities. Go to manifest and choose the activity that you want to set the theme on.

SPECIFIC ACTIVITY

AndroidManifest.xml

<application
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name">

    <activity android:name=".FirstActivity"
        android:label="@string/app_name"
        android:theme="@style/MyTheme">
    </activity>
</application>

Notice that I have set the FirstActivity theme to the custom theme MyTheme. This way the theme will only be affected on certain activity. If you don't want to hide toolbar for all your activity then try this approach.

The second approach is where you set the theme to all of your activity.

ALL ACTIVITY

<application
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/MyTheme">

    <activity android:name=".FirstActivity"
        android:label="@string/app_name">
    </activity>
</application>

Notice that I have set the application theme to the custom theme MyTheme. This way the theme will only be affected on all of activity. If you want to hide toolbar for all your activity then try this approach instead.

Improved One-Liner answer: If you are looking for a boolean return value, we can do it better by adding isPresent:

return dataSource.getParkingLots().stream().filter(parkingLot -> Objects.equals(parkingLot.getId(), id)).findFirst().isPresent();

Look at DATEADD

SELECT DATEADD(mm, 1, OrderDate)AS TimeFrame

Here's the MSDN

In your case

...WHERE reference_dt = DATEADD(MM,1, myColDate)

To understand sed command, we have to build it step by step.

Here is your original text

user@linux:~$ echo "Here is a String"
Here is a String
user@linux:~$ 

Let's try to remove Here string with substition option in sed

user@linux:~$ echo "Here is a String" | sed 's/Here //'
is a String
user@linux:~$ 

At this point, I believe you would be able to remove String as well

user@linux:~$ echo "Here is a String" | sed 's/String//'
Here is a
user@linux:~$ 

But this is not your desired output.

To combine two sed commands, use -e option

user@linux:~$ echo "Here is a String" | sed -e 's/Here //' -e 's/String//'
is a
user@linux:~$ 

Hope this helps

I found the answer here: How can I delete all git branches which have been merged?

git branch --merged | grep -v "\*" | xargs -n 1 git branch -d

Make sure we keep master

You can ensure that master, or any other branch for that matter, doesn't get removed by adding another grep after the first one. In that case you would go:

git branch --merged | grep -v "\*" | grep -v "YOUR_BRANCH_TO_KEEP" | xargs -n 1 git branch -d

So if we wanted to keep master, develop and staging for instance, we would go:

git branch --merged | grep -v "\*" | grep -v "master" | grep -v "develop" | grep -v "staging" | xargs -n 1 git branch -d

Make this an alias

Since it's a bit long, you might want to add an alias to your .zshrc or .bashrc. Mine is called gbpurge (for git branches purge):

alias gbpurge='git branch --merged | grep -v "\*" | grep -v "master" | grep -v "develop" | grep -v "staging" | xargs -n 1 git branch -d'

Then reload your .bashrc or .zshrc:

. ~/.bashrc

or

. ~/.zshrc

Dates should be used as immutable points in time; Calendars are mutable, and can be passed around and modified if you need to collaborate with other classes to come up with a final date. Consider them analogous to String and StringBuilder and you'll understand how I consider they should be used.

(And yes, I know Date isn't actually technically immutable, but the intention is that it should not be mutable, and if nothing calls the deprecated methods then it is so.)

Modern Java version of Steffi Keran's answer

public class Solution {
    public static void main(String[] args) {
        // create a simple hash map and insert some key-value pairs into it
        Map<String, Integer> map = new HashMap<>();
        map.put("Python", 3);
        map.put("C", 0);
        map.put("JavaScript", 4);
        map.put("C++", 1);
        map.put("Golang", 5);
        map.put("Java", 2);
        // Create a linked list from the above map entries
        List<Map.Entry<String, Integer>> list = new LinkedList<>(map.entrySet());
        // sort the linked list using Collections.sort()
        list.sort(Comparator.comparing(Map.Entry::getValue));
        list.forEach(System.out::println);
    }
}

There are a couple of different ways to approach the problem:

1. Wrap command-line programs
2. use a Python library that provides SSH capabilities (eg - Paramiko or Twisted Conch)

Each approach has its own quirks. You will need to setup SSH keys to enable password-less logins if you are wrapping system commands like "ssh", "scp" or "rsync." You can embed a password in a script using Paramiko or some other library, but you might find the lack of documentation frustrating, especially if you are not familiar with the basics of the SSH connection (eg - key exchanges, agents, etc). It probably goes without saying that SSH keys are almost always a better idea than passwords for this sort of stuff.

NOTE: its hard to beat rsync if you plan on transferring files via SSH, especially if the alternative is plain old scp.

I've used Paramiko with an eye towards replacing system calls but found myself drawn back to the wrapped commands due to their ease of use and immediate familiarity. You might be different. I gave Conch the once-over some time ago but it didn't appeal to me.

If opting for the system-call path, Python offers an array of options such as os.system or the commands/subprocess modules. I'd go with the subprocess module if using version 2.4+.

In my case:

• The phone was connected as a media device.
• Clicked on that message and got a menu. "USB computer connection"
• In that menu chose to connect it as a camera (for devices that do not support MTP)

And then it worked.

See the announcement for ASP.NET Core 3 Preview 4, which explains that this tool is no longer built-in and requires an explicit install:

The dotnet ef tool is no longer part of the .NET Core SDK

This change allows us to ship dotnet ef as a regular .NET CLI tool that can be installed as either a global or local tool. For example, to be able to manage migrations or scaffold a DbContext, install dotnet ef as a global tool typing the following command:

dotnet tool install --global dotnet-ef

To install a specific version of the tool, use the following command:

dotnet tool install --global dotnet-ef --version 3.1.4

The reason for the change is explained in the docs:

Why

This change allows us to distribute and update dotnet ef as a regular .NET CLI tool on NuGet, consistent with the fact that the EF Core 3.0 is also always distributed as a NuGet package.

In addition, you might need to add the following NuGet packages to your project:

• Microsoft.EntityFrameworkCore.SqlServer
• Microsoft.EntityFrameworkCore.Design
• Microsoft.EntityFrameworkCore.Tools

If we want to add custom HTTP headers to a POST request, we must pass them through a dictionary to the headers parameter.

Here is an example with a non-empty body and headers:

import requests
import json

url = 'https://somedomain.com'
body = {'name': 'Maryja'}
headers = {'content-type': 'application/json'}

r = requests.post(url, data=json.dumps(body), headers=headers)

Good question. These two operators work the same in PHP and C#.

| is a bitwise OR. It will compare two values by their bits. E.g. 1101 | 0010 = 1111. This is extremely useful when using bit options. E.g. Read = 01 (0X01) Write = 10 (0X02) Read-Write = 11 (0X03). One useful example would be opening files. A simple example would be:

File.Open(FileAccess.Read | FileAccess.Write);  //Gives read/write access to the file

|| is a logical OR. This is the way most people think of OR and compares two values based on their truth. E.g. I am going to the store or I will go to the mall. This is the one used most often in code. For example:

if(Name == "Admin" || Name == "Developer") { //allow access } //checks if name equals Admin OR Name equals Developer

You could try setInterval() instead:

Is it possible to add onclick to a div and have it occur if any area of the div is clicked.

Yes … although it should be done with caution. Make sure there is some mechanism that allows keyboard access. Build on things that work

If yes then why is the onclick method not going through to my div.

You are assigning a string where a function is expected.

divTag.onclick = printWorking;

There are nicer ways to assign event handlers though, although older versions of Internet Explorer are sufficiently different that you should use a library to abstract it. There are plenty of very small event libraries and every major library jQuery) has event handling functionality.

That said, now it is 2019, older versions of Internet Explorer no longer exist in practice so you can go direct to addEventListener

A date-time object is not a String

The java.sql.Timestamp class has no format. Its toString method generates a String with a format.

Do not conflate a date-time object with a String that may represent its value. A date-time object can parse strings and generate strings but is not itself a string.

java.time

First convert from the troubled old legacy date-time classes to java.time classes. Use the new methods added to the old classes.

Instant instant = mySqlDate.toInstant() ;

Lose the fraction of a second you don't want.

instant = instant.truncatedTo( ChronoUnit.Seconds );

Assign the time zone to adjust from UTC used by Instant.

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = instant.atZone( z );

Generate a String close to your desired output. Replace its T in the middle with a SPACE.

DateTimeFormatter f = DateTimeFormatter.ISO_LOCAL_DATE_TIME ;
String output = zdt.format( f ).replace( "T" , " " );

The pack method sizes the frame so that all its contents are at or above their preferred sizes. An alternative to pack is to establish a frame size explicitly by calling setSize or setBounds (which also sets the frame location). In general, using pack is preferable to calling setSize, since pack leaves the frame layout manager in charge of the frame size, and layout managers are good at adjusting to platform dependencies and other factors that affect component size.

From Java tutorial

You should also refer to Javadocs any time you need additional information on any Java API

npm link pain:

-Module name gulp-task

-Project name project-x

You want to link gulp-task:

1: Go to the gulp-task directory then do npm link this will symlink the project to your global modules

2: Go to your project project-x then do npm install make sure to remove the current node_modules directory

Now you want to remove this madness and use the real gulp-task, we have two options:

Option 1: Unlink via npm:

1: Go to your project and do npm unlink gulp-task this will remove the linked installed module

2: Go to the gulp-task directory and do npm unlink to remove symlink. Notice we didn't use the name of the module

3: celebrate

What if this didn't work, verify by locating your global installed module. My are location ls -la /usr/local/lib/node_modules/ if you are using nvm it will be a different path

Option 2: Remove the symlink like a normal linux guru

1: locate your global dependencies cd /usr/local/lib/node_modules/

2: removing symlink is simply using the rm command

rm gulp-task make sure you don't have / at the end

rm gulp-task/ is wrong

rm gulp-task ??

You can use sheet.addMergedRegion(rowFrom,rowTo,colFrom,colTo);

example sheet.addMergedRegion(new CellRangeAddress(1,1,1,4)); will merge from B2 to E2. Remember it is zero based indexing (ex. POI version 3.12).

One from a couple of hours that I wasted:

If you've applied all these tips and are only going on 500 errors because you don't have access to the server error log, maybe the problem isn't in the .htaccess but in the files it redirects to.

After I had fixed my .htaccess-problem I spent two more hours trying to fix it some more, even though I simply had forgotten about some permissions.

You can use the non-capturing group and a pipe delim list of items to remove.

perl -le '@ar=(1 .. 20);@x=(8,10,3,17);$x=join("|",@x);@ar=grep{!/^(?:$x)$/o} @ar;print "@ar"'

That very well may be a false positive. Like the warning message says, it is common for a capture to start in the middle of a tcp session. In those cases it does not have that information. If you are really missing acks then it is time to start looking upstream from your host for where they are disappearing. It is possible that tshark can not keep up with the data and so it is dropping some metrics. At the end of your capture it will tell you if the "kernel dropped packet" and how many. By default tshark disables dns lookup, tcpdump does not. If you use tcpdump you need to pass in the "-n" switch. If you are having a disk IO issue then you can do something like write to memory /dev/shm. BUT be careful because if your captures get very large then you can cause your machine to start swapping.

My bet is that you have some very long running tcp sessions and when you start your capture you are simply missing some parts of the tcp session due to that. Having said that, here are some of the things that I have seen cause duplicate/missing acks.

1. Switches - (very unlikely but sometimes they get in a sick state)
2. Routers - more likely than switches, but not much
3. Firewall - More likely than routers. Things to look for here are resource exhaustion (license, cpu, etc)
4. Client side filtering software - antivirus, malware detection etc.

try using dedicated functions from high level programming languages. JavaScript .getSeconds(); suits here:

var specifiedTime = new Date("November 02, 2017 06:00:00");
var specifiedTimeSeconds = specifiedTime.getSeconds(); 

var currentTime = new Date();
var currentTimeSeconds = currentTime.getSeconds(); 

alert(specifiedTimeSeconds-currentTimeSeconds);

My vies is:

Problem: Object belongs to some process(VM) and it's lifetime is the same

Serialisation - transform object state into stream of bytes(JSON, XML...) for saving, sharing, transforming...

Marshalling - contains Serialisation + codebase. Usually it used by Remote procedure call(RPC) -> Java Remote Method Invocation(Java RMI) where you are able to invoke a object's method which is hosted on remote Java processes.

codebase - is a place or URL to class definition where it can be downloaded by ClassLoader. CLASSPATH^[About] is as a local codebase

JVM -> Class Loader -> load class definition -> class

Very simple diagram for RMI

Serialisation - state
Marshalling - state + class definition

    | OnAwakeLogicController(); | Its called when MainLogicController is loaded into the memory , its also hold the following actions :- <br> 1. Checking Audio Settings <br>2. Initializing Level Controller|

Here you have an example working on py2.6 and py3.2:

from scipy.stats import norm
import matplotlib.mlab as mlab
import matplotlib.pyplot as plt

# read data from a text file. One number per line
arch = "test/Log(2)_ACRatio.txt"
datos = []
for item in open(arch,'r'):
    item = item.strip()
    if item != '':
        try:
            datos.append(float(item))
        except ValueError:
            pass

# best fit of data
(mu, sigma) = norm.fit(datos)

# the histogram of the data
n, bins, patches = plt.hist(datos, 60, normed=1, facecolor='green', alpha=0.75)

# add a 'best fit' line
y = mlab.normpdf( bins, mu, sigma)
l = plt.plot(bins, y, 'r--', linewidth=2)

#plot
plt.xlabel('Smarts')
plt.ylabel('Probability')
plt.title(r'$\mathrm{Histogram\ of\ IQ:}\ \mu=%.3f,\ \sigma=%.3f$' %(mu, sigma))
plt.grid(True)

plt.show()

If you use the credential file at ~/.aws/credentials and use the default profile as below:

[default]
aws_access_key_id=<your access key>
aws_secret_access_key=<your secret access key>

You do not need to use BasicAWSCredential or AWSCredentialsProvider. The SDK can pick up the credentials from the default profile, just by initializing the client object with the default constructor. Example below:

AmazonEC2Client ec2Client = new AmazonEC2Client();

In addition sometime you would need to initialize the client with the ClientConfiguration to provide proxy settings etc. Example below.

ClientConfiguration clientConfiguration = new ClientConfiguration();
clientConfiguration.setProxyHost("proxyhost");
clientConfiguration.setProxyPort(proxyport);
AmazonEC2Client ec2Client = new AmazonEC2Client(clientConfiguration);

You can try using groovy. It runs on the JVM and it comes with great support for running external processes and extracting the output:

http://groovy.codehaus.org/Executing+External+Processes+From+Groovy

You can see in this code taken from the same link how groovy makes it easy to get the status of the process:

println "return code: ${ proc.exitValue()}"
println "stderr: ${proc.err.text}"
println "stdout: ${proc.in.text}" // *out* from the external program is *in* for groovy

If you want to know if a property exists in an instance of a class that you have defined, simply combine property_exists() with isset().

public function hasProperty($property)
{
    return property_exists($this, $property) && isset($this->$property);
}

I realize this is an old question, but it pops up in Google when you search for 'javascript dictionaries', so I'd like to add to the above answers that in ECMAScript 6, the official Map object has been introduced, which is a dictionary implementation:

var dict = new Map();
dict.set("foo", "bar");

//returns "bar"
dict.get("foo");

Unlike javascript's normal objects, it allows any object as a key:

var foo = {};
var bar = {};
var dict = new Map();
dict.set(foo, "Foo");
dict.set(bar, "Bar");

//returns "Bar"
dict.get(bar);

//returns "Foo"
dict.get(foo);

//returns undefined, as {} !== foo and {} !== bar
dict.get({});

_.unique no longer works for the current version of Lodash as version 4.0.0 has this breaking change. The functionality of _.unique was splitted into _.uniq, _.sortedUniq, _.sortedUniqBy, and _.uniqBy.

You could use _.uniqBy like this:

_.uniqBy(data, function (e) {
  return e.id;
});

...or like this:

_.uniqBy(data, 'id');

Documentation: https://lodash.com/docs#uniqBy

For older versions of Lodash (< 4.0.0 ):

Assuming that the data should be uniqued by each object's id property and your data is stored in data variable, you can use the _.unique() function like this:

_.unique(data, function (e) {
  return e.id;
});

Or simply like this:

_.uniq(data, 'id');

Also note that I have no explicit "setter" methods (e.g. setDefaultUrl) in my class and I don't want to create any just for the purposes of testing.

One way to resolve this is change your class to use Constructor Injection, that is used for testing and Spring injection. No more reflection :)

So, you can pass any String using the constructor:

class MySpringClass {

    private final String defaultUrl;
    private final String defaultrPassword;

    public MySpringClass (
         @Value("#{myProps['default.url']}") String defaultUrl, 
         @Value("#{myProps['default.password']}") String defaultrPassword) {
        this.defaultUrl = defaultUrl;
        this.defaultrPassword= defaultrPassword;
    }

}

And in your test, just use it:

MySpringClass MySpringClass  = new MySpringClass("anyUrl", "anyPassword");

You can use the contains selector to search for elements containing a specific text

var elem = $('div.text_div:contains("This div contains some text")')?;
elem.text(elem.text().replace("contains", "Hello everyone"));

??????????????????????????????????????????

How about

SELECT id, COUNT(IF status=42 THEN 1 ENDIF) AS cnt
FROM table
GROUP BY table

Shorter than CASE :)

Works because COUNT() doesn't count null values, and IF/CASE return null when condition is not met and there is no ELSE.

I think it's better than using SUM().

My solution which can be compiled in Xcode 5:

#ifdef __IPHONE_8_0
    NSUInteger code = [CLLocationManager authorizationStatus];
    if (code == kCLAuthorizationStatusNotDetermined && ([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)] || [self.locationManager respondsToSelector:@selector(requestWhenInUseAuthorization)])) {
        // choose one request according to your business.
        if([[NSBundle mainBundle] objectForInfoDictionaryKey:@"NSLocationAlwaysUsageDescription"]){
            [self.locationManager requestAlwaysAuthorization];
        } else if([[NSBundle mainBundle] objectForInfoDictionaryKey:@"NSLocationWhenInUseUsageDescription"]) {
            [self.locationManager  requestWhenInUseAuthorization];
        } else {
            NSLog(@"Info.plist does not contain NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription");
        }
    }
#endif
    [self.locationManager startUpdatingLocation];

2019 Update (just for reference):

Starting with .NET Core 3.0, this feature is supported out of the box. To take advantage of the single-file executable publishing, just add the following line to the project configuration file:

<PropertyGroup>
  <PublishSingleFile>true</PublishSingleFile>
</PropertyGroup>

Now, dotnet publish should produce a single .exe file without using any external tool.

More documentation for this feature is available at https://github.com/dotnet/designs/blob/master/accepted/single-file/design.md.

Another way to wait for maximum of certain amount say 10 seconds of time for the element to be displayed as below:

(new WebDriverWait(driver, 10)).until(new ExpectedCondition<Boolean>() {
            public Boolean apply(WebDriver d) {
                return d.findElement(By.id("<name>")).isDisplayed();

            }
        });

Errors

I wanted to address the error's people are getting. Because the errors drove me nuts too... On a mac if you install xattr in python, then your environment may have an issue.

There are two different paths on my mac for xattr

type -a xattr

    # xattr is /usr/local/bin/xattr    # PYTHON Installed Version
    # xattr is /usr/bin/xattr          # Mac OSX Installed Version

So in one of the example's where -c will not work in xargs is because in bash you default to the non-python version.

Works with -c

/usr/bin/xattr -c

Does NOT Work with -c

/usr/local/bin/xattr -c
    # option -c not recognized

My Shell/Terminal defaults to /usr/local/bin/xattr because my $PATH /usr/local/bin: is before /usr/bin: which I believe is the default.

I can prove this because, if you try to uninstall the python xattr you will see:

pip3 uninstall xattr
Uninstalling xattr-0.9.6:
  Would remove:
    /usr/local/bin/xattr
    /usr/local/lib/python3.7/site-packages/xattr-0.9.6.dist-info/*
    /usr/local/lib/python3.7/site-packages/xattr/*
Proceed (y/n)?

Workarounds

To Fix option -c not recognized Errors.

1. Uninstall any Python xattr you may have: pip3 uninstall xattr
2. Close all Terminal windows & quit Terminal
3. Reopen a new Terminal window.
4. ReRun xattr command and it should now work.

OR

If you want to keep the Python xattr then use

/usr/bin/xattr

for any Shell commands in Terminal

Example:

Python's version of xattr doesn't handle images at all:

You can always load a json data

here i defined Chart as namespace

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

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

            });

You can use a subquery:

SELECT *
FROM terms
WHERE id IN (SELECT term_id FROM terms_relation WHERE taxonomy='categ');

and if you need to show all columns from both tables:

SELECT t.*, tr.*
FROM terms t, terms_relation tr
WHERE t.id = tr.term_id
AND tr.taxonomy='categ'

raw_input returns a string (a sequence of characters). In Python, multiplying a string and a float makes no defined meaning (while multiplying a string and an integer has a meaning: "AB" * 3 is "ABABAB"; how much is "L" * 3.14 ? Please do not reply "LLL|"). You need to parse the string to a numerical value.

You might want to try:

salesAmount = float(raw_input("Insert sale amount here\n"))

You are getting this error because the value cannot be found in the range. String or integer doesn't matter. Best thing to do in my experience is to do a check first to see if the value exists.

I used CountIf below, but there is lots of different ways to check existence of a value in a range.

Public Sub test()

Dim rng As Range
Dim aNumber As Long

aNumber = 666

Set rng = Sheet5.Range("B16:B615")

    If Application.WorksheetFunction.CountIf(rng, aNumber) > 0 Then

        rowNum = Application.WorksheetFunction.Match(aNumber, rng, 0)

    Else
        MsgBox aNumber & " does not exist in range " & rng.Address
    End If

End Sub

ALTERNATIVE WAY

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Long

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    If Not IsError(Application.Match(aNumber, rng, 0)) Then
        rowNum = Application.Match(aNumber, rng, 0)
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

OR

Public Sub test()
    Dim rng As Range
    Dim aNumber As Variant
    Dim rowNum As Variant

    aNumber = "2gg"

    Set rng = Sheet5.Range("B1:B20")

    rowNum = Application.Match(aNumber, rng, 0)

    If Not IsError(rowNum) Then
        MsgBox rowNum
    Else
        MsgBox "error"
    End If
End Sub

Try this one. it works for me. :)

I also disabled Hyper-V to makes mine work.

Genymotion FAQ

To date, VirtualBox is not yet fully compatible with Windows 10. As Genymotion relies on the use of VirtualBox in the background, some problems may arise. If you have any troubles running Genymotion on Windows 10, we first recommend that you put VirtualBox in a clean state. To do so:

1. Uninstall VirtualBox.Reboot your computer if prompted by the installer.
2. Install the version of VirtualBox recommended for Windows 10 Reboot your computer if prompted by the installer.
3. Open VirtualBox and go to File > Preferences > Network.
4. Remove all existing host-only networks by clicking Description 1.
5. Start Genymotion a first time.
6. In the event of a failure, start Genymotion a second time.

If Genymotion still doesn’t run, you can manually configure a host-only network:

1. Open VirtualBox and go to File > Preferences > Network.
2. Add a new host-only network by clicking Description 1.
3. Edit its configuration by clicking Description 1.
4. In the Adapter tab, set the following values: IPv4 Address: 192.168.56.1 IPv4 Network Mask: 255.255.255.0
5. In the DHCP Server tab, set the following values: Check Enable Server. Server Address: 192.168.56.100 Server Mask: 255.255.255.0 Lower Address Bound: 192.168.56.101 Upper Address Bound: 192.168.56.254

For best performance I recommend doing DataFrame.drop_duplicates followed up aggfunc='count'.

Others are correct that aggfunc=pd.Series.nunique will work. This can be slow, however, if the number of index groups you have is large (>1000).

So instead of (to quote @Javier)

df2.pivot_table('X', 'Y', 'Z', aggfunc=pd.Series.nunique)

I suggest

df2.drop_duplicates(['X', 'Y', 'Z']).pivot_table('X', 'Y', 'Z', aggfunc='count')

This works because it guarantees that every subgroup (each combination of ('Y', 'Z')) will have unique (non-duplicate) values of 'X'.

Adding to ben.bourdin answer, you can at least in any HTML based application, check if the browser supports HLS in its video element:

Let´s assume that your video element ID is "myVideo", then through javascript you can use the "canPlayType" function (http://www.w3schools.com/tags/av_met_canplaytype.asp)

var videoElement = document.getElementById("myVideo");
if(videoElement.canPlayType('application/vnd.apple.mpegurl') === "probably" || videoElement.canPlayType('application/vnd.apple.mpegurl') === "maybe"){
    //Actions like playing the .m3u8 content
}
else{
    //Actions like playing another video type
}

The canPlayType function, returns:

"" when there is no support for the specified audio/video type

"maybe" when the browser might support the specified audio/video type

"probably" when it most likely supports the specified audio/video type (you can use just this value in the validation to be more sure that your browser supports the specified type)

Hope this help :)

Best regards!

hierynomus/sshj has a complete implementation of SFTP version 3 (what OpenSSH implements)

Example code from SFTPUpload.java

package net.schmizz.sshj.examples;

import net.schmizz.sshj.SSHClient;
import net.schmizz.sshj.sftp.SFTPClient;
import net.schmizz.sshj.xfer.FileSystemFile;

import java.io.File;
import java.io.IOException;

/** This example demonstrates uploading of a file over SFTP to the SSH server. */
public class SFTPUpload {

    public static void main(String[] args)
            throws IOException {
        final SSHClient ssh = new SSHClient();
        ssh.loadKnownHosts();
        ssh.connect("localhost");
        try {
            ssh.authPublickey(System.getProperty("user.name"));
            final String src = System.getProperty("user.home") + File.separator + "test_file";
            final SFTPClient sftp = ssh.newSFTPClient();
            try {
                sftp.put(new FileSystemFile(src), "/tmp");
            } finally {
                sftp.close();
            }
        } finally {
            ssh.disconnect();
        }
    }

}

Apply

startActivity(new Intent(FirstActivity.this,SecondActivity.class));

then

overridePendingTransition(0, 0);

This will stop the animation.

I had just duplicated an existing scheme and added another configuration to the project. I had to add a configuration with the same name to the framework's project in order for it to also build in the same DerivedData/($AppName)/Build/Products/($CONFIGURATION_NAME) folder. Otherwise the .framework file doesn't get created and therefore can't be imported.

This builds on Jon Willis's answer that relies upon assert, which only gets executed in Debug compilations:

func Log(_ str: String) { 
    assert(DebugLog(str)) 
}
func DebugLog(_ str: String) -> Bool { 
    print(str) 
    return true
}

My use case is for logging print statements. Here is a benchmark for Release version on iPhone X:

let iterations = 100_000_000
let time1 = CFAbsoluteTimeGetCurrent()
for i in 0 ..< iterations {
    Log ("? unarchiveArray:\(fileName) memoryTime:\(memoryTime) count:\(array.count)")
}
var time2 = CFAbsoluteTimeGetCurrent()
print ("Log: \(time2-time1)" )

prints:

Log: 0.0

Looks like Swift 4 completely eliminates the function call.

If you want to show the name of processes and kill them by the command of the kill, I recommended using this script to kill all python3 running process and set your ram memory free :

ps auxww | grep 'python3' | awk '{print $2}' | xargs kill -9

use spans. ex) <span style='color: #FF0000;'>January 30, 2011</span>

You should also be able to do:

apt install sudo

sudo -i -u tomcat

Then you should be the tomcat user. It's not clear which Linux distribution you're using, but this works with Ubuntu 18.04 LTS, for example.

I had the same problem in Visual Studio Pro 2017: missing MSVCP120.dll file in Release mode and missing MSVCP120d.dll file in Debug mode. I installed Visual C++ Redistributable Packages for Visual Studio 2013 and Update for Visual C++ 2013 and Visual C++ Redistributable Package as suggested here Microsoft answer this fixed the release mode. For the debug mode what eventually worked was to copy msvcp120d.dll and msvcr120d.dll from a different computer (with Visual studio 2013) into C:\Windows\System32

In Identity inspector change class name with the corresponding identifier and also In Attributes inspector modify Indentifier then it should work as expected.

Use String.Format:

string title1 = "Sample Title One";
string element1 = "Element One";
string format = "{0,-20} {1,-10}";

string result = string.Format(format, title1, element1);
//or you can print to Console directly with
//Console.WriteLine(format, title1, element1);

In the format {0,-20} means the first argument has a fixed length 20, and the negative sign guarantees the string is printed from left to right.

You have a couple of problems here.

First, the XSD has an issue where an element is both named or referenced; in your case should be referenced.

Change:

<xsd:element name="stock" ref="Stock" minOccurs="1" maxOccurs="unbounded"/> 

To:

<xsd:element name="stock" type="Stock" minOccurs="1" maxOccurs="unbounded"/> 

And:

• Remove the declaration of the global element Stock
• Create a complex type declaration for a type named Stock

So:

<xsd:element name="Stock">
    <xsd:complexType>

To:

<xsd:complexType name="Stock">

Make sure you fix the xml closing tags.

The second problem is that the correct way to reference an external XSD is to use XSD schema with import/include within a wsdl:types element. wsdl:import is reserved to referencing other WSDL files. More information is available by going through the WS-I specification, section WSDL and Schema Import. Based on WS-I, your case would be:

INCORRECT: (the way you showed it)

<?xml version="1.0" encoding="UTF-8"?>
<definitions targetNamespace="http://stock.com/schemas/services/stock/wsdl"
    .....xmlns:external="http://stock.com/schemas/services/stock"
    <import namespace="http://stock.com/schemas/services/stock" location="Stock.xsd" />
    <message name="getStockQuoteResp">
        <part name="parameters" element="external:getStockQuoteResponse" />
    </message>
</definitions>

CORRECT:

<?xml version="1.0" encoding="UTF-8"?>
<definitions targetNamespace="http://stock.com/schemas/services/stock/wsdl"
    .....xmlns:external="http://stock.com/schemas/services/stock"
    <types>
        <schema xmlns="http://www.w3.org/2001/XMLSchema">
            <import namespace="http://stock.com/schemas/services/stock" schemaLocation="Stock.xsd" />             
        </schema>
    </types>
    <message name="getStockQuoteResp">
        <part name="parameters" element="external:getStockQuoteResponse" />
    </message>
</definitions>

SOME processors may support both syntaxes. The XSD you put out shows issues, make sure you first validate the XSD.

It would be better if you go the WS-I way when it comes to WSDL authoring.

Other issues may be related to the use of relative vs. absolute URIs in locating external content.

1) Plug in Phone through USB (w/ Developer Debugging options enabled)

2) Open Terminal and Navigate to your Android SDK (for Mac):

cd ~/Library/Android/sdk/platform-tools

3) Logcat from that directory (in your terminal) to generate a constant flow of logs (for Mac):

./adb logcat

4) Open your app that crashes to generate crash logs

5) Ctrl+C to stop terminal and look for the logs associated with the app that crashes. It may say something like the following:

AndroidRuntime: FATAL EXCEPTION: main

I did not manage to find a way to do it directly.

Instead I imported the bak file into SQL Server 2008 Express, and then used MySQL Migration Toolkit.

Worked like a charm!

Understanding that the Angular documents call checking the $$phase an anti-pattern, I tried to get $timeout and _.defer to work.

The timeout and deferred methods create a flash of unparsed {{myVar}} content in the dom like a FOUT. For me this was not acceptable. It leaves me without much to be told dogmatically that something is a hack, and not have a suitable alternative.

The only thing that works every time is:

if(scope.$$phase !== '$digest'){ scope.$digest() }.

I don't understand the danger of this method, or why it's described as a hack by people in the comments and the angular team. The command seems precise and easy to read:

"Do the digest unless one is already happening"

In CoffeeScript it's even prettier:

scope.$digest() unless scope.$$phase is '$digest'

What's the issue with this? Is there an alternative that won't create a FOUT? $safeApply looks fine but uses the $$phase inspection method, too.

A great way is to use set_exception_handler.

Warning!!! with PHP 7, you might get a white screen of death for fatal errors. For example, if you call a method on a non-object you would normally get Fatal error: Call to a member function your_method() on null and you would expect to see this if error reporting is on.

The above error will NOT be caught with catch(Exception $e). The above error will NOT trigger any custom error handler set by set_error_handler.

You must use catch(Error $e){ } to catch errors in PHP7. . This could help:

class ErrorHandler{
    public static function excep_handler($e)
    {
        print_r($e);
    }
}
set_exception_handler(array('ErrorHandler','excep_handler'));

1. Create function that parses incoming string (say "AABBCC") as a table of strings (in particular "AA", "BB", "CC").
2. Select IDs from your table and use CROSS APPLY the function with data as argument so you'll have as many rows as values contained in the current row's data. No need of cursors or stored procs.

try running after changing file name from '-' to `_'

for eg: .\my_app\my_fle.bat

instead of .\\my-app\my-fle.bat

Or

cd my_app  
 .\my_file.bat

It's the directory where java was run from, where you started the JVM. Does not have to be within the user's home directory. It can be anywhere where the user has permission to run java.

So if you cd into /somedir, then run your program, user.dir will be /somedir.

A different property, user.home, refers to the user directory. As in /Users/myuser or /home/myuser or C:\Users\myuser.

See here for a list of system properties and their descriptions.

Add this line to your floated element selector

.floated {
    float: left;
    ...
    box-sizing: border-box;
}

It will prevent padding and borders to be added to width, so element always stay in row, even if you have eg. three elements with width of 33.33333%

Note: An incorrect revision of this answer was edited out. Please review all answers.

A subselect in the WHERE clause to retrieve the greatest BALANCE aggregated over all rows. If multiple ID values share that balance value, all would be returned.

SELECT 
  ID,
  BALANCE
FROM CUSTOMERS
WHERE BALANCE = (SELECT MAX(BALANCE) FROM CUSTOMERS)

You can sort it std::sort(v, v + 2000)

Use a subquery in the where clause. For a delete query requirig a join, this example will delete rows that are unmatched in the joined table "docx_document" and that have a create date > 120 days in the "docs_documents" table.

delete from docs_documents d
where d.id in (
    select a.id from docs_documents a
    left join docx_document b on b.id = a.document_id
    where b.id is null
        and floor(sysdate - a.create_date) > 120
 );

You can do this as:

WITH abc AS( select
             FROM ...)
, XYZ AS(select
         From abc ....) /*This one uses "abc" multiple times*/
  Select 
  From XYZ....   /*using abc, XYZ multiple times*/

I came here looking for an answer to my distorted images. Not totally sure about what the op is looking for above, but I found that adding in align-items: center would solve it for me. Reading the docs, it makes sense to override this if you are flexing images directly, since align-items: stretch is the default. Another solution is to wrap your images with a div first.

.myFlexedImage {
  display: flex;
  flex-flow: row nowrap;
  align-items: center;
}

Old question, modern answer. Using object destructuring, an ECMAScript 6 feature, it's as simple as:

const { a, ...rest } = { a: 1, b: 2, c: 3 };

Or with the questions sample:

const myObject = {"ircEvent": "PRIVMSG", "method": "newURI", "regex": "^http://.*"};
const { regex, ...newObject } = myObject;
console.log(newObject);

You can see it in action in the Babel try-out editor.

Edit:

To reassign to the same variable, use a let:

let myObject = {"ircEvent": "PRIVMSG", "method": "newURI", "regex": "^http://.*"};
({ regex, ...myObject } = myObject);
console.log(myObject);

Use a packet analyzer to intercept the packets to/from somewhere.com. Studying those packets should tell you what is going on.

Time-outs or connections refused could mean that the remote host is too busy.

I don't believe there's anything built-in for this. It's made tricky by the fact that it's rare for a single line to change several times without the rest of the file changing substantially too, so you'll tend to end up with the line numbers changing a lot.

If you're lucky enough that the line always has some identifying characteristic, e.g. an assignment to a variable whose name never changed, you could use the regex choice for git blame -L. For example:

git blame -L '/variable_name *= */',+1

But this only finds the first match for that regex, so if you don't have a good way of matching the line, it's not too helpful.

You could hack something up, I suppose. I don't have time to write out code just now, but... something along these lines. Run git blame -n -L $n,$n $file. The first field is the previous commit touched, and the second field is the line number in that commit, since it could've changed. Grab those, and run git blame -n $n,$n $commit^ $file, i.e. the same thing starting from the commit before the last time the file was changed.

(Note that this will fail you if the last commit that changed the line was a merge commit. The primary way this could happen if the line was changed as part of a merge conflict resolution.)

Edit: I happened across this mailing list post from March 2011 today, which mentions that tig and git gui have a feature that will help you do this. It looks like the feature has been considered, but not finished, for git itself.

You can use java.awt.Robot to achieve this task.

There is an open-source library that has such a function, and it has cross-platform implementations: https://github.com/OpenHFT/Java-Thread-Affinity

It may be overkill just to get the PID, but if you want other things like CPU and thread id, and specifically thread affinity, it may be adequate for you.

To get the current thread's PID, just call Affinity.getAffinityImpl().getProcessId().

This is implemented using JNA (see arcsin's answer).

Also remember one thing. Very important
You have to specify the command something like this to be more precise
grep -l "pattern" *

How do you change your cursor to the finger (like for clicking on links) instead of the regular pointer?

This is very simple to achieve using the CSS property cursor, no jQuery needed.

You can read more about in: CSS cursor property and cursor - CSS | MDN

.default {_x000D_
  cursor: default;_x000D_
}_x000D_
.pointer {_x000D_
  cursor: pointer;_x000D_
}

<a class="default" href="#">default</a>_x000D_
_x000D_
<a class="pointer" href="#">pointer</a>

You can create a class in Typescript as follows:

export class coordinate {
        static x: number;
        static y: number;
        static gradient() {
            return y/x;
        }
    }

and reference it's properties and methods "without" instantiation so:

coordinate.x = 10;
coordinate.y = 10;
console.log(`x of ${coordinate.x} and y of ${coordinate.y} has gradient of ${coordinate.gradient()}`);

Fyi using backticks `` in conjunction with interpolation syntax ${} allows ease in mixing code with text :-)

As per the GNU Make manual and also pointed by 'bobbogo' in the below answer, you can use info / warning / error to display text.

$(error   text…)
$(warning text…)
$(info    text…)

To print variables,

$(error   VAR is $(VAR))
$(warning VAR is $(VAR))
$(info    VAR is $(VAR))

'error' would stop the make execution, after showing the error string

Your and should be a && in the where clause.

where epl.DepartAirportAfter >  sd.UTCDepartureTime 
and epl.ArriveAirportBy > sd.UTCArrivalTime

should be

where epl.DepartAirportAfter >  sd.UTCDepartureTime 
&& epl.ArriveAirportBy > sd.UTCArrivalTime

Code from Jonathan M looks to complicated for me so I rewrote it and got about 30% on FF v30 and 60% on Chrome v35 speed boost (http://jsperf.com/number-formating2):

    decPlaces = isNaN(decPlaces = Math.abs(decPlaces)) ? 2 : decPlaces;
    decSeparator = decSeparator == undefined ? "." : decSeparator;
    thouSeparator = thouSeparator == undefined ? "," : thouSeparator;

    var n = this.toFixed(decPlaces);
    if (decPlaces) {
        var i = n.substr(0, n.length - (decPlaces + 1));
        var j = decSeparator + n.substr(-decPlaces);
    } else {
        i = n;
        j = '';
    }

    function reverse(str) {
        var sr = '';
        for (var l = str.length - 1; l >= 0; l--) {
            sr += str.charAt(l);
        }
        return sr;
    }

    if (parseInt(i)) {
        i = reverse(reverse(i).replace(/(\d{3})(?=\d)/g, "$1" + thouSeparator));
    }
    return i+j;
};

Usage:

var sum = 123456789.5698;
var formatted = '$' + sum.formatNumber(2,',','.'); // "$123,456,789.57"

Your path includes " at the beginning and at the end. Drop the quotes, and it'll be ok.

The \" at the beginning and end of what you see in VS Debugger is what tells us that the quotes are literally in the string.

EDIT: LINQ to Objects doesn't behave how I'd expected it to. You may well be interested in the blog post I've just written about this...

They're different in terms of what will be called - the first is equivalent to:

Collection.Where(x => x.Age == 10)
          .Where(x => x.Name == "Fido")
          .Where(x => x.Fat == true)

wheras the latter is equivalent to:

Collection.Where(x => x.Age == 10 && 
                      x.Name == "Fido" &&
                      x.Fat == true)

Now what difference that actually makes depends on the implementation of Where being called. If it's a SQL-based provider, I'd expect the two to end up creating the same SQL. If it's in LINQ to Objects, the second will have fewer levels of indirection (there'll be just two iterators involved instead of four). Whether those levels of indirection are significant in terms of speed is a different matter.

Typically I would use several where clauses if they feel like they're representing significantly different conditions (e.g. one is to do with one part of an object, and one is completely separate) and one where clause when various conditions are closely related (e.g. a particular value is greater than a minimum and less than a maximum). Basically it's worth considering readability before any slight performance difference.

this works with "NA" not for NA

comments = c("no","yes","NA")
  for (l in 1:length(comments)) {
    #if (!is.na(comments[l])) print(comments[l])
    if (comments[l] != "NA") print(comments[l])
  }
