cp -Rvn /source/path/* /destination/path/
cp: /destination/path/any.zip: No such file or directory

It will create no existing paths in destination, if path have a source file inside. This dont create empty directories.

A moment ago i've seen xxxxxxxx: No such file or directory, because i run out of free space. without error message.

with ditto:

ditto -V /source/path/* /destination/path
ditto: /destination/path/any.zip: No space left on device

once freed space cp -Rvn /source/path/* /destination/path/ works as expected

No, you can't undo, rollback or reverse a commit.

STOP THE DATABASE!

(Note: if you deleted the data directory off the filesystem, do NOT stop the database. The following advice applies to an accidental commit of a DELETE or similar, not an rm -rf /data/directory scenario).

If this data was important, STOP YOUR DATABASE NOW and do not restart it. Use pg_ctl stop -m immediate so that no checkpoint is run on shutdown.

You cannot roll back a transaction once it has commited. You will need to restore the data from backups, or use point-in-time recovery, which must have been set up before the accident happened.

If you didn't have any PITR / WAL archiving set up and don't have backups, you're in real trouble.

Urgent mitigation

Once your database is stopped, you should make a file system level copy of the whole data directory - the folder that contains base, pg_clog, etc. Copy all of it to a new location. Do not do anything to the copy in the new location, it is your only hope of recovering your data if you do not have backups. Make another copy on some removable storage if you can, and then unplug that storage from the computer. Remember, you need absolutely every part of the data directory, including pg_xlog etc. No part is unimportant.

Exactly how to make the copy depends on which operating system you're running. Where the data dir is depends on which OS you're running and how you installed PostgreSQL.

Ways some data could've survived

If you stop your DB quickly enough you might have a hope of recovering some data from the tables. That's because PostgreSQL uses multi-version concurrency control (MVCC) to manage concurrent access to its storage. Sometimes it will write new versions of the rows you update to the table, leaving the old ones in place but marked as "deleted". After a while autovaccum comes along and marks the rows as free space, so they can be overwritten by a later INSERT or UPDATE. Thus, the old versions of the UPDATEd rows might still be lying around, present but inaccessible.

Additionally, Pg writes in two phases. First data is written to the write-ahead log (WAL). Only once it's been written to the WAL and hit disk, it's then copied to the "heap" (the main tables), possibly overwriting old data that was there. The WAL content is copied to the main heap by the bgwriter and by periodic checkpoints. By default checkpoints happen every 5 minutes. If you manage to stop the database before a checkpoint has happened and stopped it by hard-killing it, pulling the plug on the machine, or using pg_ctl in immediate mode you might've captured the data from before the checkpoint happened, so your old data is more likely to still be in the heap.

Now that you have made a complete file-system-level copy of the data dir you can start your database back up if you really need to; the data will still be gone, but you've done what you can to give yourself some hope of maybe recovering it. Given the choice I'd probably keep the DB shut down just to be safe.

Recovery

You may now need to hire an expert in PostgreSQL's innards to assist you in a data recovery attempt. Be prepared to pay a professional for their time, possibly quite a bit of time.

I posted about this on the Pg mailing list, and ?????? ?????? linked to depesz's post on pg_dirtyread, which looks like just what you want, though it doesn't recover TOASTed data so it's of limited utility. Give it a try, if you're lucky it might work.

See: pg_dirtyread on GitHub.

I've removed what I'd written in this section as it's obsoleted by that tool.

See also PostgreSQL row storage fundamentals

Prevention

See my blog entry Preventing PostgreSQL database corruption.

On a semi-related side-note, if you were using two phase commit you could ROLLBACK PREPARED for a transction that was prepared for commit but not fully commited. That's about the closest you get to rolling back an already-committed transaction, and does not apply to your situation.

In case any one stumbles upon this as I just have...

Find First blank cell in a column(I'm using column D but didn't want to include D1)

NextFree = Range("D2:D" & Rows.Count).Cells.SpecialCells(xlCellTypeBlanks).Row
Range("D" & NextFree).Select

NextFree is just a name, you could use sausages if you wanted.

The best tool for doing layouts using grid, IMHO, is graph paper and a pencil. I know you're asking for some type of program, but it really does work. I've been doing Tk programming for a couple of decades so layout comes quite easily for me, yet I still break out graph paper when I have a complex GUI.

Another thing to think about is this: The real power of Tkinter geometry managers comes from using them together*. If you set out to use only grid, or only pack, you're doing it wrong. Instead, design your GUI on paper first, then look for patterns that are best solved by one or the other. Pack is the right choice for certain types of layouts, and grid is the right choice for others. For a very small set of problems, place is the right choice. Don't limit your thinking to using only one of the geometry managers.

* The only caveat to using both geometry managers is that you should only use one per container (a container can be any widget, but typically it will be a frame).

Screen

If process is running in a screen session you can use screen's log command to log the output of that window to a file:

Switch to the script's window, C-a H to log.
Now you can :

$ tail -f screenlog.2 | grep whatever

From screen's man page:

log [on|off]

Start/stop writing output of the current window to a file "screenlog.n" in the window's default directory, where n is the number of the current window. This filename can be changed with the 'logfile' command. If no parameter is given, the state of logging is toggled. The session log is appended to the previous contents of the file if it already exists. The current contents and the contents of the scrollback history are not included in the session log. Default is 'off'.

I'm sure tmux has something similar as well.

Adding some code snippets to support the accepted answer.

Directory structure :

setup/
 |__docker/DockerFile
 |__target/scripts/<myscripts.sh>
src/
 |__<my source files>

Docker file entry:

RUN mkdir -p /home/vagrant/dockerws/chatServerInstaller/scripts/
RUN mkdir -p /home/vagrant/dockerws/chatServerInstaller/src/
WORKDIR /home/vagrant/dockerws/chatServerInstaller

#Copy all the required files from host's file system to the container file system.
COPY setup/target/scripts/install_x.sh scripts/
COPY setup/target/scripts/install_y.sh scripts/
COPY src/ src/

Command used to build the docker image

docker build -t test:latest -f setup/docker/Dockerfile .

You need to include the protocol scheme:

'http://192.168.1.61:8080/api/call'

Without the http:// part, requests has no idea how to connect to the remote server.

Note that the protocol scheme must be all lowercase; if your URL starts with HTTP:// for example, it won’t find the http:// connection adapter either.

If a computer can run it, a suitably motivated human can reverse-engineer it.

Multi thread example to calculate directory size from Microsoft Docs, which would be faster

using System;
using System.IO;
using System.Threading;
using System.Threading.Tasks;

public class Example
{
   public static void Main()
   {
      long totalSize = 0;

      String[] args = Environment.GetCommandLineArgs();
      if (args.Length == 1) {
         Console.WriteLine("There are no command line arguments.");
         return;
      }
      if (! Directory.Exists(args[1])) {
         Console.WriteLine("The directory does not exist.");
         return;
      }

      String[] files = Directory.GetFiles(args[1]);
      Parallel.For(0, files.Length,
                   index => { FileInfo fi = new FileInfo(files[index]);
                              long size = fi.Length;
                              Interlocked.Add(ref totalSize, size);
                   } );
      Console.WriteLine("Directory '{0}':", args[1]);
      Console.WriteLine("{0:N0} files, {1:N0} bytes", files.Length, totalSize);
   }
}
// The example displaysoutput like the following:
//       Directory 'c:\windows\':
//       32 files, 6,587,222 bytes

This example only calculate the files in current folder, so if you want to calculate all the files recursively, you can change the

String[] files = Directory.GetFiles(args[1]);

to

String[] files = Directory.GetFiles(args[1], "*", SearchOption.AllDirectories);

git log --full-history -- [file path] shows the changes of a file and works even if the file was deleted.

Example:

git log --full-history  -- myfile

If you want to see only the last commit, which deleted the file, use -1 in addition to the command above. Example:

git log --full-history -1 -- [file path]

See also my article: Which commit deleted a file.

I am using this and it works for me with Jquery:

Jquery:

var checkbox = $('[name="remember"]');

if (checkbox.is(':checked'))
{
    console.log('The checkbox is checked');
}else
{
    console.log('The checkbox is not checked');
}

Is very simple, but work's.

Regards!

@Mark Rajcok gave a great solution for ion projects that include a range type input.

In any other case of non ion projects I will suggest this:

HTML:

<input type="text" name="points" #points maxlength="8" [(ngModel)]="range" (ngModelChange)="range=saverange($event, points)">

Component:

    onChangeAchievement(eventStr: string, eRef): string {

      //Do something (some manipulations) on input and than return it to be saved:

       //In case you need to force of modifing the Element-Reference value on-focus of input:
       var eventStrToReplace = eventStr.replace(/[^0-9,eE\.\+]+/g, "");
       if (eventStr != eventStrToReplace) {
           eRef.value = eventStrToReplace;
       }

      return this.getNumberOnChange(eventStr);

    }

The idea here:

1. Letting the (ngModelChange) method to do the Setter job:

   (ngModelChange)="range=saverange($event, points)

2. Enabling direct access to the native Dom element using this call:

   eRef.value = eventStrToReplace;

Since a stored procedure is created, altered and dropped using queries you actually CAN manage them using phpMyAdmin.

To create a stored procedure, you can use the following (change as necessary) :

CREATE PROCEDURE sp_test()
BEGIN
  SELECT 'Number of records: ', count(*) from test;
END//

And make sure you set the "Delimiter" field on the SQL tab to //.

Once you created the stored procedure it will appear in the Routines fieldset below your tables (in the Structure tab), and you can easily change/drop it.

To use the stored procedure from PHP you have to execute a CALL query, just like you would do in plain SQL.

There is no float type. Looks like you want float64. You could also use float32 if you only need a single-precision floating point value.

package main

import "fmt"

func main() {
    i := 5
    f := float64(i)
    fmt.Printf("f is %f\n", f)
}

After installing the gems, if you want to know where a particular gem is. Try typing:

 gem list

You will be able to see the list of gems you have installed. Now use bundle show and name the gem you want to know the path for, like this:

 bundle show <gemName>

Or (as of younger versions of bundler):

 bundle info <gemName>

Do this to use a profile with name 'dev':

session = boto3.session.Session(profile_name='dev')
s3 = session.resource('s3')
for bucket in s3.buckets.all():
    print(bucket.name)

After upgrading to Mountain Lion using the NDK, I had the following error:

Cannot find 'make' program. Please install Cygwin make package or define the GNUMAKE variable to point to it

Error was fixed by downloading and using the latest NDK

The & operator takes the intersection of two sets.

{1, 2, 3} & {2, 3, 4}
Out[1]: {2, 3}

But the problem with this code is that, I cannot change the content popup content from "Please enter your name" to my html form.

Umm. Just change the string passed to the prompt() function.

While searching, I found that there we CANNOT change the content of popup Prompt Box

You can't change the title. You can change the content, it is the first argument passed to the prompt() function.

You can download image by Asyn task use this class:

public class ImageDownloaderTask extends AsyncTask<String, Void, Bitmap> {

    private final WeakReference<ImageView> imageViewReference;
    private final MemoryCache memoryCache;
    private final BrandItem brandCatogiriesItem;
    private Context context;
    private String url;

    public ImageDownloaderTask(ImageView imageView, String url, Context context) {
        imageViewReference = new WeakReference<ImageView>(imageView);
        memoryCache = new MemoryCache();
        brandCatogiriesItem = new BrandItem();
        this.url = url;
        this.context = context;
    }

    @Override
    protected Bitmap doInBackground(String... params) {

        return downloadBitmap(params[0]);
    }

    @Override
    protected void onPostExecute(Bitmap bitmap) {
        if (isCancelled()) {
            bitmap = null;
        }

        if (imageViewReference != null) {
            ImageView imageView = imageViewReference.get();
            if (imageView != null) {
                if (bitmap != null) {
                    memoryCache.put("1", bitmap);
                    brandCatogiriesItem.setUrl(url);
                    brandCatogiriesItem.setThumb(bitmap);
                    // BrandCatogiriesItem.saveLocalBrandOrCatogiries(context, brandCatogiriesItem);
                    imageView.setImageBitmap(bitmap);
                } else {
                    Drawable placeholder = imageView.getContext().getResources().getDrawable(R.drawable.placeholder);
                    imageView.setImageDrawable(placeholder);
                }
            }

        }
    }

    private Bitmap downloadBitmap(String url) {
        HttpURLConnection urlConnection = null;
        try {
            URL uri = new URL(url);
            urlConnection = (HttpURLConnection) uri.openConnection();

            int statusCode = urlConnection.getResponseCode();
            if (statusCode != HttpStatus.SC_OK) {
                return null;
            }

            InputStream inputStream = urlConnection.getInputStream();
            if (inputStream != null) {

                Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
                return bitmap;
            }
        } catch (Exception e) {
            Log.d("URLCONNECTIONERROR", e.toString());
            if (urlConnection != null) {
                urlConnection.disconnect();
            }
            Log.w("ImageDownloader", "Error downloading image from " + url);
        } finally {
            if (urlConnection != null) {
                urlConnection.disconnect();

            }
        }
        return null;
    }
}

And call this like:

new ImageDownloaderTask(thumbImage, item.thumbnail, context).execute(item.thumbnail);

I've just applied Nepster's solution and works like a charm. There is a minor modification to run it from a Fragment.

To your Fragment

// sending intent to onNewIntent() of MainActivity
Intent intent = new Intent(getActivity(), MainActivity.class);
intent.putExtra("transparent_nav_changed", true);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);

And to your OnNewIntent() of the Activity you would like to restart.

// recreate activity when transparent_nav was just changed
if (getIntent().getBooleanExtra("transparent_nav_changed", false)) {
    finish(); // finish and create a new Instance
    Intent restarter = new Intent(MainActivity.this, MainActivity.class);
    startActivity(restarter);
}

From your example it seems reasonable to assume that the siteIP column is determined by the siteName column (that is, each site has only one siteIP). If this is indeed the case, then there is a simple solution using group by:

select
  sites.siteName,
  sites.siteIP,
  max(history.date)
from sites
inner join history on
  sites.siteName=history.siteName
group by
  sites.siteName,
  sites.siteIP
order by
  sites.siteName;

However, if my assumption is not correct (that is, it is possible for a site to have multiple siteIP), then it is not clear from you question which siteIP you want the query to return in the second column. If just any siteIP, then the following query will do:

select
  sites.siteName,
  min(sites.siteIP),
  max(history.date)
from sites
inner join history on
  sites.siteName=history.siteName
group by
  sites.siteName
order by
  sites.siteName;

This works flawlessly @ 2019

See this question for additional information.

Many answers for this questions are great and some have even looked into the corner cases. I would like to add a simple answer that can be of daily use... where you mostly get into those corner cases (like having escaped commas or commas in quotes etc.,).

FS (Field Separator) is the variable whose value is dafaulted to space. So awk by default splits at space for any line.

So using BEGIN (Execute before taking input) we can set this field to anything we want...

awk 'BEGIN {FS = ","}; {print $3}'

The above code will print the 3rd column in a csv file.

I think you should put

`

(backtick) symbols around your variable.

Things to remember:

When custom modules are used (modules other than AppModule) then it is necessary to import the common module in it.

yourmodule.module.ts

import { CommonModule } from '@angular/common';

@NgModule({
  imports: [
    CommonModule
  ],
  exports:[ ],
  declarations: []
})

apache-tomcat-8.0.33

If you want to enable debug logging in tomcat for TLD scanned jars then you have to change /conf/logging.properties file in tomcat directory.

uncomment the line :
org.apache.jasper.servlet.TldScanner.level = FINE

FINE level is for debug log.

This should work for normal tomcat.

If the tomcat is running under eclipse. Then you have to set the path of tomcat logging.properties in eclipse.

1. Open servers view in eclipse.Stop the server.Double click your tomcat server.
   This will open Overview window for the server.
2. Click on Open launch configuration.This will open another window.
3. Go to the Arguments tab(second tab).Go to VM arguments section.
4. paste this two line there :-
   -Djava.util.logging.config.file="{CATALINA_HOME}\conf\logging.properties"
   -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
   Here CATALINA_HOME is your PC's corresponding tomcat server directory.
5. Save the Changes.Restart the server.

Now the jar files that scanned for TLDs should show in the log.

The property you are looking for that first td is rowspan: http://www.angelfire.com/fl5/html-tutorial/tables/tr_code.htm

<table>
<tr><td rowspan="2"></td><td colspan='4'></td></tr>
<tr><td></td><td></td><td></td><td></td></tr>
<tr><td></td><td></td><td></td><td></td><td></td></tr>
</table>

Try just

sudo service mysql restart

It worked for me

SELECT PersonName, songName, status
FROM table
WHERE name IN ('Holly', 'Ryan')

If you are using parametrized Stored procedure:

1. Pass in comma separated string
2. Use special function to split comma separated string into table value variable
3. Use INNER JOIN ON t.PersonName = newTable.PersonName using a table variable which contains passed in names

If the characters you want to remove are always the same characters, then consider chomp:

'abc123'.chomp('123')    # => "abc"

The advantages of chomp are: no counting, and the code more clearly communicates what it is doing.

With no arguments, chomp removes the DOS or Unix line ending, if either is present:

"abc\n".chomp      # => "abc"
"abc\r\n".chomp    # => "abc"

From the comments, there was a question of the speed of using #chomp versus using a range. Here is a benchmark comparing the two:

require 'benchmark'

S = 'asdfghjkl'
SL = S.length
T = 10_000
A = 1_000.times.map { |n| "#{n}#{S}" }

GC.disable

Benchmark.bmbm do |x|
  x.report('chomp') { T.times { A.each { |s| s.chomp(S) } } }
  x.report('range') { T.times { A.each { |s| s[0...-SL] } } }
end

Benchmark Results (using CRuby 2.13p242):

Rehearsal -----------------------------------------
chomp   1.540000   0.040000   1.580000 (  1.587908)
range   1.810000   0.200000   2.010000 (  2.011846)
-------------------------------- total: 3.590000sec

            user     system      total        real
chomp   1.550000   0.070000   1.620000 (  1.610362)
range   1.970000   0.170000   2.140000 (  2.146682)

So chomp is faster than using a range, by ~22%.

I don't know if it's possible to do ranges in awk. You could do a for loop, but you would have to add handling to filter out the columns you don't want. It's probably easier to do this:

awk -F, '{OFS=",";print $1,$2,$3,$4,$5,$6,$7,$8,$9,$10,$20,$21,$22,$23,$24,$25,$30,$33}' infile.csv > outfile.csv

something else to consider - and this faster and more concise:

cut -d "," -f1-10,20-25,30-33 infile.csv > outfile.csv

As to the second part of your question, I would probably write a script in perl that knows how to handle header rows, parsing the columns names from stdin or a file and then doing the filtering. It's probably a tool I would want to have for other things. I am not sure about doing in a one liner, although I am sure it can be done.

Spring is a collection of best-practise API patterns, you can write up a shopping list of them as long as your arm. The way that the API is designed encourages you (but doesn't force you) to follow these patterns, and half the time you follow them without knowing you are doing so.

The way to get the results of your formula would be to start in a new sheet.

In cell A1 put the formula

=IF('testsheet'!C1 <= 99,'testsheet'!A1,"") 

Copy that cell down to row 40 In cell B1 put the formula

=A1

In cell B2 put the formula

=B1 & A2

Copy that cell down to row 40.

The value you want is now in that column in row 40.

Not really the answer you want, but that is the fastest way to get things done excel wise without creating a custom formula that takes in a range and makes the calculation (which would be more fun to do).

Try this,

return RedirectToAction("ActionEventName", "Controller", new { ID = model.ID, SiteID = model.SiteID });

Here i mention you are pass multiple values or model also. That's why here i mention that.

Just click on the certificate in the keychain access and change the access permission if you want to avoid entering password at all, else select Always allow and it will prompt probably 4-5 times and it will be done.

What you are trying to do is add additional information to each item in the list that you already created so

    alist[ 'from form', 'stuff 2', 'stuff 3']

    for j in range( 0,len[alist]):
        temp= []
        temp.append(alist[j]) # alist[0] is 'from form' 
        temp.append('t') # slot for first piece of data 't'
        temp.append('-') # slot for second piece of data

    blist.append(temp)      # will be alist with 2 additional fields for extra stuff assocated with each item in alist  

The SQL dialect converts the HQL query which we write in our java or any other object oriented program to the specific database SQL.

For example in the java suppose I write List employees = session.createQuery("FROM Employee").list();

but when my dialect is <property name="hibernate.dialect"> org.hibernate.dialect.MySQLDialect

The HQL ("FROM Employee") gets converted to "SELECT * FROM EMPLOYEE" before hitting the MySQL database

There is a better way than having to manually navigate to https://url , knowing what button to click in what browser, knowing where and how to save the "certificate" file and finally knowing the magic incantation for the keytool to install it locally.

Just do this:

1. Save code below to InstallCert.java
2. Open command line and execute: javac InstallCert.java
3. Run like: java InstallCert <host>[:port] [passphrase] (port and passphrase are optional)

Here is the code for InstallCert, note the year in header, will need to modify some parts for "later" versions of java:

add external jar of jstl-standard.jar as the external jar by right click on JRE system libraries under configure build path -> build path. it worked for me!!

The other big difference is Abandon does not remove items immediately, but when it does then cleanup it does a loop over session items to check for STA COM objects it needs to handle specially. And this can be a problem.

Under high load it's possible for two (or more) requests to make it to the server for the same session (that is two requests with the same session cookie). Their execution will be serialized, but since Abandon doesn't clear out the items synchronously but rather sets a flag it's possible for both requests to run, and both requests to schedule a work item to clear out session "later". Both these work items can then run at the same time, and both are checking the session objects, and both are clearing out the array of objects, and what happens when you have two things iterating over a list and changing it?? Boom! And since this happens in a queueuserworkitem callback and is NOT done in a try/catch (thanks MS), it will bring down your entire app domain. Been there.

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

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

    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 100, 30)];
    label.text = @"Your String.";
    label.layer.cornerRadius = 8.0;
    [self.view addSubview:label];

This should work properly just try it.

import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/of';

If you have a valid integer value and your requirement is to compare values, you can simply go ahead with the comparison as seen below.

Sub t()

Dim i As Integer
Dim s  As String

' pass
i = 65
s = "65"
If i = s Then
MsgBox i
End If

' fail - Type Mismatch
i = 65
s = "A"
If i = s Then
MsgBox i
End If
End Sub

Some examples:

async function loadItems() { try { let response = await fetch(https://url/${AppID}); let result = await response.json(); return result; } catch (err) { } }

async function addItem(item) {
    try {
        let response = await fetch("https://url", {
            method: "POST",
            body: JSON.stringify({
                AppId: appId,
                Key: item,
                Value: item,
                someBoolean: false,
            }),
            headers: {
                "Content-Type": "application/json",
            },
        });
        let result = await response.json();
        return result;
    } catch (err) {
    }
}

async function removeItem(id) {
    try {
        let response = await fetch(`https://url/${id}`, {
            method: "DELETE",
        });
    } catch (err) {
    }
}

async function updateItem(item) {
    try {
        let response = await fetch(`https://url/${item.id}`, {
            method: "PUT",
            body: JSON.stringify(todo),
            headers: {
                "Content-Type": "application/json",
            },
        });
    } catch (err) {
    }
}

you may have multiple separators, including whitespace characters, commas, semicolons, etc. take those in repeatable group with []+, like:

 String[] tokens = "a , b,  ,c; ;d,      ".split( "[,; \t\n\r]+" );

you'll have 4 tokens -- a, b, c, d

leading separators in the source string need to be removed before applying this split.

as answer to question asked:

String data = "5|6|7||8|9||";
String[] split = data.split("[\\| \t\n\r]+");

whitespaces added just in case if you'll have those as separators along with |

Your code works as is for me. I'm verifying this by using netcat on Linux.

Using netcat, I can do nc -ul 127.0.0.1 5005 which will listen for packets at:

• IP: 127.0.0.1
• Port: 5005
• Protocol: UDP

That being said, here's the output that I see when I run your script, while having netcat running.

[9:34am][wlynch@watermelon ~] nc -ul 127.0.0.1 5005
Hello, World!

An alternative way to (not dynamically) link a text to activate a worksheet without macros is to make the selected string an actual link. You can do this by selecting the cell that contains the text and press CTRL+K then select the option/tab 'Place in this document' and select the tab you want to activate. If you would click the text (that is now a link) the configured sheet will become active/selected.

Add the following to the top of your file # coding=utf-8

If you go to the link in the error you can seen the reason why:

Defining the Encoding

Python will default to ASCII as standard encoding if no other encoding hints are given. To define a source code encoding, a magic comment must be placed into the source files either as first or second line in the file, such as: # coding=

If none of the options in the select have a selected attribute, the first option will be the one selected.

In order to select a default option that is not the first, add a selected attribute to that option:

<option selected="selected">Select a language</option>

You can read the HTML 4.01 spec regarding defaults in select element.

I suggest reading a good HTML book if you need to learn HTML basics like this - I recommend Head First HTML.

It's not that different from uploading one file - $_FILES is an array containing any and all uploaded files.

There's a chapter in the PHP manual: Uploading multiple files

If you want to enable multiple file uploads with easy selection on the user's end (selecting multiple files at once instead of filling in upload fields) take a look at SWFUpload. It works differently from a normal file upload form and requires Flash to work, though. SWFUpload was obsoleted along with Flash. Check the other, newer answers for the now-correct approach.

echo

Not having return type

print

Have return type

print_r()

Outputs as formatted,

Judging by the declaration and description of the startsWith Java function, the "most straight forward way" to implement it in VBA would either be with Left:

Public Function startsWith(str As String, prefix As String) As Boolean
    startsWith = Left(str, Len(prefix)) = prefix
End Function

Or, if you want to have the offset parameter available, with Mid:

Public Function startsWith(str As String, prefix As String, Optional toffset As Integer = 0) As Boolean
    startsWith = Mid(str, toffset + 1, Len(prefix)) = prefix
End Function

if your SQL query is like this

SELECT col-1, col-2 FROM tableName WHERE col-1=apple,col-2=mango
GROUPBY col-3 HAVING Count(col-4) > 5  ORDERBY col-2 DESC LIMIT 15;

Then for query() method, we can do as:-

String table = "tableName";
String[] columns = {"col-1", "col-2"};
String selection = "col-1 =? AND col-2=?";       
String[] selectionArgs = {"apple","mango"};
String groupBy =col-3;
String having =" COUNT(col-4) > 5";
String orderBy = "col-2 DESC";
String limit = "15";

query(tableName, columns, selection, selectionArgs, groupBy, having, orderBy, limit);

I had a similar error..This might be due to two reasons. a) If you have used variables, re-evaluate the expressions in which variables are used and make sure the expression is evaluated without errors. b) If you are deleting the excel sheet and creating excel sheet on the fly in your package.

If double-clicking the .jar file in Windows Explorer works, then you should be able to use this:

start myapp.jar

in your batch file.

The Windows start command does exactly the same thing behind the scenes as double-clicking a file.

shell("cls") if on Windows,

shell("clear") if on Linux or Mac.

(shell() passes a command (or any string) to the host terminal.)

Yes.

However, if you need to use Application.DoEvents, this is mostly an indication of a bad application design. Perhaps you'd like to do some work in a separate thread instead?

sender refers to the object that invoked the event that fired the event handler. This is useful if you have many objects using the same event handler.

EventArgs is something of a dummy base class. In and of itself it's more or less useless, but if you derive from it, you can add whatever data you need to pass to your event handlers.

When you implement your own events, use an EventHandler or EventHandler<T> as their type. This guarantees that you'll have exactly these two parameters for all your events (which is a good thing).

You can try this also to replace existing object

toDoTaskList = [
                {id:'abcd', name:'test'},
                {id:'abcdc', name:'test'},
                {id:'abcdtr', name:'test'}
              ];

newRecordToUpdate = {id:'abcdc', name:'xyz'};
this.toDoTaskList.map((todo, i) => {
         if (todo.id == newRecordToUpdate .id){
            this.toDoTaskList[i] = updatedVal;
          }
        });

So, say you have your View with PartialView, which have to be updated by button click:

<div class="target">
    @{ Html.RenderAction("UpdatePoints");}
</div>

<input class="button" value="update" />

There are some ways to do it. For example you may use jQuery:

<script type="text/javascript">
    $(function(){    
        $('.button').on("click", function(){        
            $.post('@Url.Action("PostActionToUpdatePoints", "Home")').always(function(){
                $('.target').load('/Home/UpdatePoints');        
            })        
        });
    });        
</script>

PostActionToUpdatePoints is your Action with [HttpPost] attribute, which you use to update points

If you use logic in your action UpdatePoints() to update points, maybe you forgot to add [HttpPost] attribute to it:

[HttpPost]
public ActionResult UpdatePoints()
{    
    ViewBag.points =  _Repository.Points;
    return PartialView("UpdatePoints");
}

If you use a static key, encrypt and decrypt always give the same result;

public static final String CRYPTOR_KEY = "your static key here";
byte[] keyByte = Base64.getDecoder().decode(CRYPTOR_KEY);
key = new SecretKeySpec(keyByte, "AES");

You can use the built-in forEach function for arrays.

Like this:

//this sets all product descriptions to a max length of 10 characters
data.products.forEach( (element) => {
    element.product_desc = element.product_desc.substring(0,10);
});

Your version wasn't wrong though. It should look more like this:

for(let i=0; i<data.products.length; i++){
    console.log(data.products[i].product_desc); //use i instead of 0
}

You can try SDWebImage, it provides:

1. Asynchronous loading
2. Caching for offline use
3. Place holder image to appear while loading
4. Works well with UITableView

Quick example:

    [cell.imageView setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"] placeholderImage:[UIImage imageNamed:@"placeholder.png"]];

Here is the solution:

1. Login to DB;
2. Run a command show full processlist;to get the process id with status and query itself which causes the database hanging;
3. Select the process id and run a command KILL <pid>; to kill that process.

Sometimes it is not enough to kill each process manually. So, for that we've to go with some trick:

1. Login to MySQL;
2. Run a query Select concat('KILL ',id,';') from information_schema.processlist where user='user'; to print all processes with KILL command;
3. Copy the query result, paste and remove a pipe | sign, copy and paste all again into the query console. HIT ENTER. BooM it's done.

Many people will suggest you use MERGE, but I caution you against it. By default, it doesn't protect you from concurrency and race conditions any more than multiple statements, but it does introduce other dangers:

http://www.mssqltips.com/sqlservertip/3074/use-caution-with-sql-servers-merge-statement/

Even with this "simpler" syntax available, I still prefer this approach (error handling omitted for brevity):

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
UPDATE dbo.table SET ... WHERE PK = @PK;
IF @@ROWCOUNT = 0
BEGIN
  INSERT dbo.table(PK, ...) SELECT @PK, ...;
END
COMMIT TRANSACTION;

A lot of folks will suggest this way:

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
IF EXISTS (SELECT 1 FROM dbo.table WHERE PK = @PK)
BEGIN
  UPDATE ...
END
ELSE
BEGIN
  INSERT ...
END
COMMIT TRANSACTION;

But all this accomplishes is ensuring you may need to read the table twice to locate the row(s) to be updated. In the first sample, you will only ever need to locate the row(s) once. (In both cases, if no rows are found from the initial read, an insert occurs.)

Others will suggest this way:

BEGIN TRY
  INSERT ...
END TRY
BEGIN CATCH
  IF ERROR_NUMBER() = 2627
    UPDATE ...
END CATCH

However, this is problematic if for no other reason than letting SQL Server catch exceptions that you could have prevented in the first place is much more expensive, except in the rare scenario where almost every insert fails. I prove as much here:

• http://www.mssqltips.com/sqlservertip/2632/checking-for-potential-constraint-violations-before-entering-sql-server-try-and-catch-logic/
• http://www.sqlperformance.com/2012/08/t-sql-queries/error-handling

Not sure what you think you gain by having a single statement; I don't think you gain anything. MERGE is a single statement but it still has to really perform multiple operations anyway - even though it makes you think it doesn't.

IMO extremely important rule of thumb for your client side js code is to keep separated the data handling and ui building logic into different funcs, which is also valid for axios data fetching ... in this way your control flow and error handlings will be much more simple and easier to manage, as it could be seen from this ok fetch

and this NOK fetch

I had the same issue and I resolved it with MySQL workbench, as shown in the attached screenshot:

1. in the navigator (on the left side), under the section "management", click on "Status and System variables",
2. then choose "system variables" (tab at the top),
3. then search for "connection" in the search field,
4. and 5. you will see two fields that need to be adjusted to fit your needs (max_connections and mysqlx_max_connections).

Hope that helps!

The system does not allow me to upload pictures, instead please click on this link and you can see my screenshot...

Use another flex container to fix the min-height issue in IE10 and IE11:

HTML

<div class="ie-fixMinHeight">
    <div id="page">
        <div id="header"></div>
        <div id="content"></div>
        <div id="footer"></div>
    </div>
</div>

CSS

.ie-fixMinHeight {
    display:flex;
}

#page {
    min-height:100vh;
    width:100%;
    display:flex;
    flex-direction:column;
}

#content {
    flex-grow:1;
}

See a working demo.

• Don't use flexbox layout directly on body because it screws up elements inserted via jQuery plugins (autocomplete, popup, etc.).
• Don't use height:100% or height:100vh on your container because the footer will stick at the bottom of window and won't adapt to long content.
• Use flex-grow:1 rather than flex:1 cause IE10 and IE11 default values for flex are 0 0 auto and not 0 1 auto.

Here is my code that is finally working

using System;
using System.IO;
using System.Net;
using System.Net.Sockets;
using System.Text.RegularExpressions;
using System.Threading;

class TelnetTest
{

    static void Main(string[] args)

        tt.ns = tt.tcpClient.GetStream();

        tt.connectHost("admin", "admin");
        tt.sendCommand();

        tt.tcpClient.Close();
    }

    bool i = true;
    while (i)
    {
        Console.WriteLine("Connecting.....");
        Byte[] output = new Byte[1024];
        String responseoutput = String.Empty;
        Byte[] cmd = System.Text.Encoding.ASCII.GetBytes("\n");
        ns.Write(cmd, 0, cmd.Length);

The desired effect can also be achieved by moving the submit button outside of the form as described here:

Prevent page reload and redirect on form submit ajax/jquery

Like this:

<form id="getPatientsForm">
    Enter URL for patient server
    <br/><br/>
    <input name="forwardToUrl" type="hidden" value="/WEB-INF/jsp/patient/patientList.jsp" />
    <input name="patientRootUrl" size="100"></input>
    <br/><br/>
</form>

<button onclick="javascript:postGetPatientsForm();">Connect to Server</button>

This is a template for a function decorator that does not require () if no parameters are to be given:

import functools


def decorator(x_or_func=None, *decorator_args, **decorator_kws):
    def _decorator(func):
        @functools.wraps(func)
        def wrapper(*args, **kws):

                    or callable(x_or_func) \
                    or x_or_func is None:
                x = ...  # <-- default `x` value
            else:
                x = x_or_func
            return func(*args, **kws)

        return wrapper

    return _decorator(x_or_func) if callable(x_or_func) else _decorator

an example of this is given below:

I got the same error message. In my case, it was due to not using quotes.

Although the column was supposed to have only numbers, it was a Varchar column, and one of the rows had a letter in it.

So I was doing this:

select * from mytable where myid = 1234

While I should be doing this:

select * from mytable where myid = '1234'

If the column had all numbers, the conversion would have worked, but not in this case.

Try making the field names legal by removing spaces. It's a long shot but it has actually helped me before.

You can use Prefix tree (trie) data structure to store words and keep track of count of words within Prefix Tree Node.

  #define  ALPHABET_SIZE 26
  // Structure of each node of prefix tree
  struct prefix_tree_node {
    prefix_tree_node() : count(0) {}
    int count;
    prefix_tree_node *child[ALPHABET_SIZE];
  };
  void insert_string_in_prefix_tree(string word)
  {
    prefix_tree_node *current = root;
    for(unsigned int i=0;i<word.size();++i){
      // Assuming it has only alphabetic lowercase characters
            // Note ::::: Change this check or convert into lower case
    const unsigned int letter = static_cast<int>(word[i] - 'a');

      // Invalid alphabetic character, then continue
      // Note :::: Change this condition depending on the scenario
      if(letter > 26)
        throw runtime_error("Invalid alphabetic character");

      if(current->child[letter] == NULL)
        current->child[letter] = new prefix_tree_node();

      current = current->child[letter];
    }
  current->count++;
  // Insert this string into Max Heap and sort them by counts
}

    // Data structure for storing in Heap will be something like this
    struct MaxHeapNode {
       int count;
       string word;
    };

After inserting all words, you have to print word and count by iterating Maxheap.

Seaborn box plot returns a matplotlib axes instance. Unlike pyplot itself, which has a method plt.title(), the corresponding argument for an axes is ax.set_title(). Therefore you need to call

sns.boxplot('Day', 'Count', data= gg).set_title('lalala')

A complete example would be:

import seaborn as sns
import matplotlib.pyplot as plt

tips = sns.load_dataset("tips")
sns.boxplot(x=tips["total_bill"]).set_title("LaLaLa")

plt.show()

Of course you could also use the returned axes instance to make it more readable:

ax = sns.boxplot('Day', 'Count', data= gg)
ax.set_title('lalala')
ax.set_ylabel('lololo')

Or, if you don't insist on using a list comprehension:

>>> mylist = ["a","b","c","d"]
>>> list(enumerate(mylist))
[(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd')]

And with HTML5 we have native DOM Mutation Observers.

It is not allocating memory at assignment of value 12 to integer pointer. Therefore it crashes, because it's not finding any memory.

You can try this:

#include<stdio.h>
#include<stdlib.h>
int *fun();

int main()
{
    int *ptr;
    ptr=fun();
    printf("\n\t\t%d\n",*ptr);
}

int *fun()
{
    int ptr;
    ptr=12;
    return(&ptr);
}

For image purpose you can do something like this

img {
    width: calc(100% + 20px); // twice the value of the parent's padding
    margin-left: -10px; // -1 * parent's padding
}

You can use the DISTINCT keyword within the COUNT aggregate function:

SELECT COUNT(DISTINCT column_name) AS some_alias FROM table_name

This will count only the distinct values for that column.

You can also concat df1, df2:

x = pd.concat([df1, df2])

and then remove all duplicates:

y = x.drop_duplicates(keep=False, inplace=False)

It is safer to do:

curl --netrc-file my-password-file http://example.com

...as passing a plain user/password string on the command line, is a bad idea.

The format of the password file is (as per man curl):

machine <example.com> login <username> password <password>

Note:

1. Machine name must not include https:// or similar! Just the hostname.
2. The words 'machine', 'login', and 'password' are just keywords; the actual information is the stuff after those keywords.

Well, yes, and no...

I understand that you want your local copies to "override" what's in the remote, but, oh, man, if someone has modified the files in the remote repo in some different way, and you just ignore their changes and try to "force" your own changes without even looking at possible conflicts, well, I weep for you (and your coworkers) ;-)

That said, though, it's really easy to do the "right thing..."

Step 1:

git stash

in your local repo. That will save away your local updates into the stash, then revert your modified files back to their pre-edit state.

Step 2:

git pull

to get any modified versions. Now, hopefully, that won't get any new versions of the files you're worried about. If it doesn't, then the next step will work smoothly. If it does, then you've got some work to do, and you'll be glad you did.

Step 3:

git stash pop

That will merge your modified versions that you stashed away in Step 1 with the versions you just pulled in Step 2. If everything goes smoothly, then you'll be all set!

If, on the other hand, there were real conflicts between what you pulled in Step 2 and your modifications (due to someone else editing in the interim), you'll find out and be told to resolve them. Do it.

Things will work out much better this way - it will probably keep your changes without any real work on your part, while alerting you to serious, serious issues.

Every datetime field in input/output needs to be in UNIX/epoch format. This avoids the confusion between developers across different sides of the API.

Pros:

• Epoch format does not have a timezone.
• Epoch has a single format (Unix time is a single signed number).
• Epoch time is not effected by daylight saving.
• Most of the Backend frameworks and all native ios/android APIs support epoch conversion.
• Local time conversion part can be done entirely in application side depends on the timezone setting of user's device/browser.

Cons:

• Extra processing for converting to UTC for storing in UTC format in the database.
• Readability of input/output.
• Readability of GET URLs.

Notes:

• Timezones are a presentation-layer problem! Most of your code shouldn't be dealing with timezones or local time, it should be passing Unix time around.
• If you want to store a humanly-readable time (e.g. logs), consider storing it along with Unix time, not instead of Unix time.

Apart from the <h:panelGroup> component (which comes as a bit of a surprise to me), you could use a <f:verbatim> tag with the escape parameter set to false to generate any mark-up you want. For example:

<f:verbatim escape="true">
    <div id="blah"></div>
</f:verbatim>

Bear in mind it's a little less elegant than the panelGroup solution, as you have to generate this for both the start and end tags if you want to wrap any of your JSF code with the div tag.

Alternatively, all the major UI Frameworks have a div component tag, or you could write your own.

I've been able to make it work on inline LI elements. Unfortunately, it does not work if the LI elements are inline-block:

Live demo: http://jsfiddle.net/dWkdp/

Or the cliff notes version:

li { 
     display: inline; 
}
li:nth-child(3):after { 
     content: "\A";
     white-space: pre; 
}

Gil's answer holds promise (the library he linked to) --- but for the time being, it still doesn't work when scrolled down on the mobile device.

I solved the issue for myself using just a snippet of CSS at the end of my CSS files:

@media (max-width: 767px) {
  #content .modal.fade.in {
    top: 5%;
  }
}

The #content selector is simply an id that wraps my html so I can override Bootstrap's specificity (set to your own id wrapping your modal html).

The downside: It's not centered vertically on the mobile devices.

The upside: It's visible, and on smaller devices, a reasonably sized modal will take up much of the screen, so the "non-centering" won't be as apparent.

Why it works:

When you're at low screen sizes with Bootstrap's responsive CSS, for devices with smaller screens, it sets .modal.fade.in's 'top' to 'auto'. For some reason the mobile webkit browsers seem to have a hard time with figuring out the vertical placement with the "auto" assignment. So just switch it back to a fixed value and it works great.

Since the modal is already set to postition: absolute, the value is relative to the viewport's height, not the document height, so it works no matter how long the page is or where you're scrolled to.

If the first segment doesn't start with / it is a relative route. router.navigate needs a relativeTo parameter for relative navigation

Either you make the route absolute:

this.router.navigate(['/foo-content', 'bar-contents', 'baz-content', 'page'], this.params.queryParams)

or you pass relativeTo

this.router.navigate(['../foo-content', 'bar-contents', 'baz-content', 'page'], {queryParams: this.params.queryParams, relativeTo: this.currentActivatedRoute})

The answer anhic gave can be very inefficient if you have a large database and the attribute name is present only in some of the documents.

To improve efficiency you can add a $match to the aggregation.

db.collection.aggregate(
    {"$match": {"name" :{ "$ne" : null } } }, 
    {"$group" : {"_id": "$name", "count": { "$sum": 1 } } },
    {"$match": {"count" : {"$gt": 1} } }, 
    {"$project": {"name" : "$_id", "_id" : 0} }
)

Beware float: left…

…there are many ways to align elements side-by-side.

Below are the most common ways to achieve two elements side-by-side…

Demo: View/edit all the below examples on Codepen

Basic styles for all examples below…

Some basic css styles for parent and child elements in these examples:

.parent {
  background: mediumpurple;
  padding: 1rem;
}
.child {
  border: 1px solid indigo;
  padding: 1rem;
}

Using the float solution my have unintended affect on other elements. (Hint: You may need to use a clearfix.)

html

<div class='parent'>
  <div class='child float-left-child'>A</div>
  <div class='child float-left-child'>B</div>
</div>

css

.float-left-child {
  float: left;
}

html

<div class='parent'>
  <div class='child inline-block-child'>A</div>
  <div class='child inline-block-child'>B</div>
</div>

css

.inline-block-child {
  display: inline-block;
}

Note: the space between these two child elements can be removed, by removing the space between the div tags:

html

<div class='parent'>
  <div class='child inline-block-child'>A</div><div class='child inline-block-child'>B</div>
</div>

css

.inline-block-child {
  display: inline-block;
}

html

<div class='parent flex-parent'>
  <div class='child flex-child'>A</div>
  <div class='child flex-child'>B</div>
</div>

css

.flex-parent {
  display: flex;
}
.flex-child {
  flex: 1;

As of today (Feb 27), there is a new For-Each toolbox on the MATLAB File Exchange that accomplishes the concept of foreach. foreach is not a part of the MATLAB language but use of this toolbox gives us the ability to emulate what foreach would do.

Here's another difference. I will... buy you a beer if you can explain the reasoning or reason as to this state of affairs:

enum Foo { a = 'a', b = 'b' }

type TFoo = {
  [k in Foo]: boolean;
}

const foo1: TFoo = { a: true, b: false} // good
// const foo2: TFoo = { a: true }       // bad: missing b
// const foo3: TFoo = { a: true, b: 0}  // bad: b is not a boolean

// So type does roughly what I'd expect and want

interface IFoo {
//  [k in Foo]: boolean;
/*
  Uncommenting the above line gives the following errors:
  A computed property name in an interface must refer to an expression whose type is a      
    literal type or a 'unique symbol' type.
  A computed property name must be of type 'string', 'number', 'symbol', or 'any'.
  Cannot find name 'k'.
*/
}

// ???

This sort of makes me want to say the hell with interfaces unless I'm intentionally implementing some OOP design pattern, or require merging as described above (which I'd never do unless I had a very good reason for it).

You can use:

f.Controls[name];

Where f is your form variable. That gives you the control with name name.

if (yourString.Length > 1)
    withoutLast = yourString.Substring(0, yourString.Length - 1);

or

if (yourString.Length > 1)
    withoutLast = yourString.TrimEnd().Substring(0, yourString.Length - 1);

...in case you want to remove a non-whitespace character from the end.

You can also get BLOB object directly from XMLHttpRequest. Setting responseType to blob makes the trick. Here is my code:

var xhr = new XMLHttpRequest();
xhr.open("GET", "http://localhost/image.jpg");
xhr.responseType = "blob";
xhr.onload = response;
xhr.send();

And the response function looks like this:

function response(e) {
   var urlCreator = window.URL || window.webkitURL;
   var imageUrl = urlCreator.createObjectURL(this.response);
   document.querySelector("#image").src = imageUrl;
}

We just have to make an empty image element in HTML:

<img id="image"/>

Other alternative way to reset the windows.timer is using the counter, as follows:

int timerCtr = 0;
Timer mTimer;

private void ResetTimer() => timerCtr = 0;
private void mTimer_Tick()
{
    timerCtr++;
    // Perform task
}  

So if you intend to repeat every 1 second, you can set the timer interval at 100ms, and test the counter to 10 cycles.

This is suitable if the timer should wait for some processes those may be ended at the different time span.

In addition to the nested scrolling NestedScrollView added one major functionality, which could even make it interesting outside of nested contexts: It has build in support for OnScrollChangeListener. Adding a OnScrollChangeListener to the original ScrollView below API 23 required subclassing ScrollView or messing around with the ViewTreeObserver of the ScrollView which often means even more work than subclassing. With NestedScrollView it can be done using the build-in setter.

HTML

<div id="products"></div>

JS

var someone = {
"name":"Mahmoude Elghandour",
"price":"174 SR",
"desc":"WE Will BE WITH YOU"
 };
 var name = $("<div/>",{"text":someone.name,"class":"name"
});

var price = $("<div/>",{"text":someone.price,"class":"price"});
var desc = $("<div />", {   
"text": someone.desc,
"class": "desc"
});
$("#products").fadeIn(1500);
$("#products").append(name).append(price).append(desc);

On Bootstrap 4, you can easily review the template option, by overriding the max-width :

$('#myButton').popover({
    placement: 'bottom',
    html: true,
    trigger: 'click',
    template: '<div class="popover" style="max-width: 500px;" role="tooltip"><div class="arrow"></div><h3 class="popover-header"></h3><div class="popover-body"></div></div>'
});

This is a good solution if you have several popovers on page.

The general methodology would be to iterate through the ArrayList, and insert the values into the HashMap. An example is as follows:

HashMap<String, Product> productMap = new HashMap<String, Product>();
for (Product product : productList) {
   productMap.put(product.getProductCode(), product);
}

Sum of arithmetical progression

(A1+AN)/2*N = (1 + (N-1))/2*(N-1) = N*(N-1)/2

See whether the below query will help

SELECT *
FROM MY_TABLE
WHERE CHARINDEX('.',MY_FIELD) = 0 AND CHARINDEX(',',MY_FIELD) = 0       
AND ISNUMERIC(MY_FIELD) = 1 AND CONVERT(FLOAT,MY_FIELD) / 2147483647 <= 1

Maybe python changed since this question, all of the below seem to work well

Python2.7

int(1324343032.324325235 * 1000) / 1000.0
float(int(1324343032.324325235 * 1000)) / 1000
round(int(1324343032.324325235 * 1000) / 1000.0,3)
# result for all of the above is 1324343032.324

If you do not use the transaction logs for restores (i.e. You only ever do full backups), you can set Recovery Mode to "Simple", and the transaction log will very shortly shrink and never fill up again.

If you are using SQL 7 or 2000, you can enable "truncate log on checkpoint" in the database options tab. This has the same effect.

This is not recomended in production environments obviously, since you will not be able to restore to a point in time.

I had a similar issue as you, although I was trying to use start to open Chrome and using the file path. I used only start chrome.exe and it opened just fine. You may want to try to do the same with exe file. Using the file path may be unnecessary.

Here are some examples (using the file name you gave in a comment on another answer):

• Instead of C:\Program^ Files\temp.exe you can try temp.exe.

• Instead of start C:\Program^ Files\temp.exe you can try start temp.exe

How to specify the JDK version?

Use any of three ways: (1) Spring Boot feature, or use Maven compiler plugin with either (2) source & target or (3) with release.

Spring Boot

1. <java.version> is not referenced in the Maven documentation.
   It is a Spring Boot specificity.
   It allows to set the source and the target java version with the same version such as this one to specify java 1.8 for both :

   1.8

Feel free to use it if you use Spring Boot.

maven-compiler-plugin with source & target

2. Using maven-compiler-plugin or maven.compiler.source/maven.compiler.target properties are equivalent.

That is indeed :

<plugins>
    <plugin>    
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
            <source>1.8</source>
            <target>1.8</target>
        </configuration>
    </plugin>
</plugins>

is equivalent to :

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

according to the Maven documentation of the compiler plugin since the <source> and the <target> elements in the compiler configuration use the properties maven.compiler.source and maven.compiler.target if they are defined.

source

The -source argument for the Java compiler.
Default value is: 1.6.
User property is: maven.compiler.source.

target

The -target argument for the Java compiler.
Default value is: 1.6.
User property is: maven.compiler.target.

About the default values for source and target, note that since the 3.8.0 of the maven compiler, the default values have changed from 1.5 to 1.6.

maven-compiler-plugin with release instead of source & target

3. The maven-compiler-plugin 3.6 and later versions provide a new way :

   org.apache.maven.plugins maven-compiler-plugin 3.8.0 9

You could also declare just :

<properties>
    <maven.compiler.release>9</maven.compiler.release>
</properties>

But at this time it will not work as the maven-compiler-plugin default version you use doesn't rely on a recent enough version.

The Maven release argument conveys release : a new JVM standard option that we could pass from Java 9 :

Compiles against the public, supported and documented API for a specific VM version.

This way provides a standard way to specify the same version for the source, the target and the bootstrap JVM options.
Note that specifying the bootstrap is a good practice for cross compilations and it will not hurt if you don't make cross compilations either.

Which is the best way to specify the JDK version?

The first way (<java.version>) is allowed only if you use Spring Boot.

For Java 8 and below :

About the two other ways : valuing the maven.compiler.source/maven.compiler.target properties or using the maven-compiler-plugin, you can use one or the other. It changes nothing in the facts since finally the two solutions rely on the same properties and the same mechanism : the maven core compiler plugin.

Well, if you don't need to specify other properties or behavior than Java versions in the compiler plugin, using this way makes more sense as this is more concise:

<properties>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

From Java 9 :

The release argument (third point) is a way to strongly consider if you want to use the same version for the source and the target.

What happens if the version differs between the JDK in JAVA_HOME and which one specified in the pom.xml?

It is not a problem if the JDK referenced by the JAVA_HOME is compatible with the version specified in the pom but to ensure a better cross-compilation compatibility think about adding the bootstrap JVM option with as value the path of the rt.jar of the target version.

An important thing to consider is that the source and the target version in the Maven configuration should not be superior to the JDK version referenced by the JAVA_HOME.
A older version of the JDK cannot compile with a more recent version since it doesn't know its specification.

To get information about the source, target and release supported versions according to the used JDK, please refer to java compilation : source, target and release supported versions.

How handle the case of JDK referenced by the JAVA_HOME is not compatible with the java target and/or source versions specified in the pom?

For example, if your JAVA_HOME refers to a JDK 1.7 and you specify a JDK 1.8 as source and target in the compiler configuration of your pom.xml, it will be a problem because as explained, the JDK 1.7 doesn't know how to compile with.
From its point of view, it is an unknown JDK version since it was released after it.
In this case, you should configure the Maven compiler plugin to specify the JDK in this way :

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <configuration>
        <source>1.8</source>
        <target>1.8</target>
        <compilerVersion>1.8</compilerVersion>      
        <fork>true</fork>
        <executable>D:\jdk1.8\bin\javac</executable>                
    </configuration>
</plugin>

You could have more details in examples with maven compiler plugin.

It is not asked but cases where that may be more complicated is when you specify source but not target. It may use a different version in target according to the source version. Rules are particular : you can read about them in the Cross-Compilation Options part.

Why the compiler plugin is traced in the output at the execution of the Maven package goal even if you don't specify it in the pom.xml?

To compile your code and more generally to perform all tasks required for a maven goal, Maven needs tools. So, it uses core Maven plugins (you recognize a core Maven plugin by its groupId : org.apache.maven.plugins) to do the required tasks : compiler plugin for compiling classes, test plugin for executing tests, and so for... So, even if you don't declare these plugins, they are bound to the execution of the Maven lifecycle.
At the root dir of your Maven project, you can run the command : mvn help:effective-pom to get the final pom effectively used. You could see among other information, attached plugins by Maven (specified or not in your pom.xml), with the used version, their configuration and the executed goals for each phase of the lifecycle.

In the output of the mvn help:effective-pom command, you could see the declaration of these core plugins in the <build><plugins> element, for example :

...
<plugin>
   <artifactId>maven-clean-plugin</artifactId>
   <version>2.5</version>
   <executions>
     <execution>
       <id>default-clean</id>
       <phase>clean</phase>
       <goals>
         <goal>clean</goal>
       </goals>
     </execution>
   </executions>
 </plugin>
 <plugin>
   <artifactId>maven-resources-plugin</artifactId>
   <version>2.6</version>
   <executions>
     <execution>
       <id>default-testResources</id>
       <phase>process-test-resources</phase>
       <goals>
         <goal>testResources</goal>
       </goals>
     </execution>
     <execution>
       <id>default-resources</id>
       <phase>process-resources</phase>
       <goals>
         <goal>resources</goal>
       </goals>
     </execution>
   </executions>
 </plugin>
 <plugin>
   <artifactId>maven-compiler-plugin</artifactId>
   <version>3.1</version>
   <executions>
     <execution>
       <id>default-compile</id>
       <phase>compile</phase>
       <goals>
         <goal>compile</goal>
       </goals>
     </execution>
     <execution>
       <id>default-testCompile</id>
       <phase>test-compile</phase>
       <goals>
         <goal>testCompile</goal>
       </goals>
     </execution>
   </executions>
 </plugin>
  ...

You can have more information about it in the introduction of the Maven lifeycle in the Maven documentation.

Nevertheless, you can declare these plugins when you want to configure them with other values as default values (for example, you did it when you declared the maven-compiler plugin in your pom.xml to adjust the JDK version to use) or when you want to add some plugin executions not used by default in the Maven lifecycle.

Use the a mode. It stands for append.

$myfile = fopen("logs.txt", "a") or die("Unable to open file!");
$txt = "user id date";
fwrite($myfile, "\n". $txt);
fclose($myfile);

You can read the lines and replace all special characters safely this way.
Keep in mind that if you use \\W you will not replace underscores.

Scanner scan = new Scanner(System.in);

while(scan.hasNextLine()){
    System.out.println(scan.nextLine().replaceAll("[^a-zA-Z0-9]", ""));
}

Are you working with Pandas?

You can use pd.to_datetime from the pandas library. Here are various options, depending on what you want returned.

import pandas as pd

pd.to_datetime('today')  # pd.to_datetime('now')
# Timestamp('2019-03-27 00:00:10.958567')

As a python datetime object,

pd.to_datetime('today').to_pydatetime()
# datetime.datetime(2019, 4, 18, 3, 50, 42, 587629)

As a formatted date string,

pd.to_datetime('today').isoformat()
# '2019-04-18T04:03:32.493337'

# Or, `strftime` for custom formats.
pd.to_datetime('today').strftime('%Y-%m-%d')
# '2019-03-27'

To get just the date from the timestamp, call Timestamp.date.

pd.to_datetime('today').date()
# datetime.date(2019, 3, 27)

Aside from to_datetime, you can directly instantiate a Timestamp object using,

pd.Timestamp('today')  # pd.Timestamp('now')
# Timestamp('2019-04-18 03:43:33.233093')

pd.Timestamp('today').to_pydatetime()
# datetime.datetime(2019, 4, 18, 3, 53, 46, 220068)

If you want to make your Timestamp timezone aware, pass a timezone to the tz argument.

pd.Timestamp('now', tz='America/Los_Angeles')
# Timestamp('2019-04-18 03:59:02.647819-0700', tz='America/Los_Angeles')

Yet another date parser library: Pendulum

This one's good, I promise.

If you're working with pendulum, there are some interesting choices. You can get the current timestamp using now() or today's date using today().

import pendulum 

pendulum.now()
# DateTime(2019, 3, 27, 0, 2, 41, 452264, tzinfo=Timezone('America/Los_Angeles'))

pendulum.today()
# DateTime(2019, 3, 27, 0, 0, 0, tzinfo=Timezone('America/Los_Angeles'))

Additionally, you can also get tomorrow() or yesterday()'s date directly without having to do any additional timedelta arithmetic.

pendulum.yesterday()
# DateTime(2019, 3, 26, 0, 0, 0, tzinfo=Timezone('America/Los_Angeles'))

pendulum.tomorrow()
# DateTime(2019, 3, 28, 0, 0, 0, tzinfo=Timezone('America/Los_Angeles'))

There are various formatting options available.

pendulum.now().to_date_string()
# '2019-03-27'

pendulum.now().to_formatted_date_string()
# 'Mar 27, 2019'

pendulum.now().to_day_datetime_string()
# 'Wed, Mar 27, 2019 12:04 AM'

Rationale for this answer

A lot of pandas users stumble upon this question because they believe it is a python question more than a pandas one. This answer aims to be useful to folks who are already using these libraries and would be interested to know that there are ways to achieve these results within the scope of the library itself.

If you are not working with pandas or pendulum already, I definitely do not recommend installing them just for the sake of running this code! These libraries are heavy and come with a lot of plumbing under the hood. It is not worth the trouble when you can use the standard library instead.

Another pitfall is that connectionString sometimes refers to the name of the connection string in the app/web-config and sometimes to the actual connection string itself and vice versa.

Very easy to fix but sometimes hard to spot.

I had similar problem with polish language

I tried:

$fileEndEnd = mb_convert_encoding($fileEndEnd, 'UTF-8', mb_detect_encoding($fileEndEnd, 'UTF-8', true));

I tried:

$fileEndEnd = utf8_encode ( $fileEndEnd );

I tried:

$fileEndEnd = iconv( "UTF-8", "UTF-8", $fileEndEnd );

And then -

$fileEndEnd = mb_convert_encoding($fileEndEnd, 'HTML-ENTITIES', "UTF-8");

This last worked perfectly !!!!!!

First and foremost, I highly recommend you buy the PDF/E-Book from PHP Architect. It's US$20, but is the only straightforward "Here's how Magento works" resource I've been able to find. I've also started writing Magento tutorials at my own website.

Second, if you have a choice, and aren't an experienced programmer or don't have access to an experienced programmer (ideally in PHP and Java), pick another cart. Magento is well engineered, but it was engineered to be a shopping cart solution that other programmers can build modules on top of. It was not engineered to be easily understood by people who are smart, but aren't programmers.

Third, Magento MVC is very different from the Ruby on Rails, Django, CodeIgniter, CakePHP, etc. MVC model that's popular with PHP developers these days. I think it's based on the Zend model, and the whole thing is very Java OOP-like. There's two controllers you need to be concerned about. The module/frontName controller, and then the MVC controller.

Fourth, the Magento application itself is built using the same module system you'll be using, so poking around the core code is a useful learning tactic. Also, a lot of what you'll be doing with Magento is overriding existing classes. What I'm covering here is creating new functionality, not overriding. Keep this in mind when you're looking at the code samples out there.

I'm going to start with your first question, showing you how to setup a controller/router to respond to a specific URL. This will be a small novel. I might have time later for the model/template related topics, but for now, I don't. I will, however, briefly speak to your SQL question.

Magento uses an EAV database architecture. Whenever possible, try to use the model objects the system provides to get the information you need. I know it's all there in the SQL tables, but it's best not to think of grabbing data using raw SQL queries, or you'll go mad.

Final disclaimer. I've been using Magento for about two or three weeks, so caveat emptor. This is an exercise to get this straight in my head as much as it is to help Stack Overflow.

Create a module

All additions and customizations to Magento are done through modules. So, the first thing you'll need to do is create a new module. Create an XML file in app/modules named as follows

cd /path/to/store/app
touch etc/modules/MyCompanyName_HelloWorld.xml

<?xml version="1.0"?>
<config>
     <modules>
        <MyCompanyName_HelloWorld>
            <active>true</active>
            <codePool>local</codePool>
        </MyCompanyName_HelloWorld>
     </modules>
</config>

MyCompanyName is a unique namespace for your modifications, it doesn't have to be your company's name, but that the recommended convention my magento. HelloWorld is the name of your module.

Clear the application cache

Now that the module file is in place, we'll need to let Magento know about it (and check our work). In the admin application

1. Go to System->Cache Management
2. Select Refresh from the All Cache menu
3. Click Save Cache settings

Now, we make sure that Magento knows about the module

1. Go to System->Configuration
2. Click Advanced
3. In the "Disable modules output" setting box, look for your new module named "MyCompanyName_HelloWorld"

If you can live with the performance slow down, you might want to turn off the application cache while developing/learning. Nothing is more frustrating then forgetting the clear out the cache and wondering why your changes aren't showing up.

Setup the directory structure

Next, we'll need to setup a directory structure for the module. You won't need all these directories, but there's no harm in setting them all up now.

mkdir -p app/code/local/MyCompanyName/HelloWorld/Block
mkdir -p app/code/local/MyCompanyName/HelloWorld/controllers
mkdir -p app/code/local/MyCompanyName/HelloWorld/Model
mkdir -p app/code/local/MyCompanyName/HelloWorld/Helper
mkdir -p app/code/local/MyCompanyName/HelloWorld/etc
mkdir -p app/code/local/MyCompanyName/HelloWorld/sql

And add a configuration file

touch app/code/local/MyCompanyName/HelloWorld/etc/config.xml

and inside the configuration file, add the following, which is essentially a "blank" configuration.

<?xml version="1.0"?>
<config>
    <modules>
        <MyCompanyName_HelloWorld>
            <version>0.1.0</version>
        </MyCompanyName_HelloWorld>
    </modules>
</config>

Oversimplifying things, this configuration file will let you tell Magento what code you want to run.

Setting up the router

Next, we need to setup the module's routers. This will let the system know that we're handling any URLs in the form of

http://example.com/magento/index.php/helloworld

So, in your configuration file, add the following section.

<config>
<!-- ... -->
    <frontend>
        <routers>
            <!-- the <helloworld> tagname appears to be arbitrary, but by
            convention is should match the frontName tag below-->
            <helloworld>
                <use>standard</use>
                <args>
                    <module>MyCompanyName_HelloWorld</module>
                    <frontName>helloworld</frontName>
                </args>
            </helloworld>
        </routers>
    </frontend>
<!-- ... -->
</config>

What you're saying here is "any URL with the frontName of helloworld ...

http://example.com/magento/index.php/helloworld

should use the frontName controller MyCompanyName_HelloWorld".

So, with the above configuration in place, when you load the helloworld page above, you'll get a 404 page. That's because we haven't created a file for our controller. Let's do that now.

touch app/code/local/MyCompanyName/HelloWorld/controllers/IndexController.php

Now try loading the page. Progress! Instead of a 404, you'll get a PHP/Magento exception

Controller file was loaded but class does not exist

So, open the file we just created, and paste in the following code. The name of the class needs to be based on the name you provided in your router.

<?php
class MyCompanyName_HelloWorld_IndexController extends Mage_Core_Controller_Front_Action{
    public function indexAction(){
        echo "We're echoing just to show that this is what's called, normally you'd have some kind of redirect going on here";
    }
}

What we've just setup is the module/frontName controller. This is the default controller and the default action of the module. If you want to add controllers or actions, you have to remember that the tree first part of a Magento URL are immutable they will always go this way http://example.com/magento/index.php/frontName/controllerName/actionName

So if you want to match this url

http://example.com/magento/index.php/helloworld/foo

You will have to have a FooController, which you can do this way :

touch app/code/local/MyCompanyName/HelloWorld/controllers/FooController.php

<?php
class MyCompanyName_HelloWorld_FooController extends Mage_Core_Controller_Front_Action{
    public function indexAction(){
        echo 'Foo Index Action';
    }

    public function addAction(){
        echo 'Foo add Action';
    }

    public function deleteAction(){
        echo 'Foo delete Action';
    }
}

Please note that the default controller IndexController and the default action indexAction can by implicit but have to be explicit if something come after it. So http://example.com/magento/index.php/helloworld/foo will match the controller FooController and the action indexAction and NOT the action fooAction of the IndexController. If you want to have a fooAction, in the controller IndexController you then have to call this controller explicitly like this way : http://example.com/magento/index.php/helloworld/index/foo because the second part of the url is and will always be the controllerName. This behaviour is an inheritance of the Zend Framework bundled in Magento.

You should now be able to hit the following URLs and see the results of your echo statements

http://example.com/magento/index.php/helloworld/foo
http://example.com/magento/index.php/helloworld/foo/add
http://example.com/magento/index.php/helloworld/foo/delete

So, that should give you a basic idea on how Magento dispatches to a controller. From here I'd recommended poking at the existing Magento controller classes to see how models and the template/layout system should be used.

Update

As of 2019 this can be easily achieved using ProgressIndicator, in Material Components library, used with the Widget.MaterialComponents.ProgressIndicator.Circular.Indeterminate style.

For more details please check Gabriele Mariotti's answer below.

Old implementation

Here is an awesome implementation of the material design circular intermediate progress bar https://gist.github.com/castorflex/4e46a9dc2c3a4245a28e. The implementation only lacks the ability add various colors like in inbox by android app but this does a pretty great job.

I upgraded from 2010 to 2013 and after changing all the projects' Platform Toolset, I need to right-click on the Solution and choose Retarget... to make it work.

String[] result = "hi i'm paul".split("\\s+"); to split across one or more cases.

Or you could take a look at Apache Common StringUtils. It has StringUtils.split(String str) method that splits string using white space as delimiter. It also has other useful utility methods

If you only need the names of the remote repositories (and not any of the other data), a simple git remote is enough.

$ git remote

Why not using jQuery.parseHTML() http://api.jquery.com/jquery.parsehtml/?

The other answers here adequately explain the security caveats which are also mentioned in the subprocess documentation. But in addition to that, the overhead of starting a shell to start the program you want to run is often unnecessary and definitely silly for situations where you don't actually use any of the shell's functionality. Moreover, the additional hidden complexity should scare you, especially if you are not very familiar with the shell or the services it provides.

Where the interactions with the shell are nontrivial, you now require the reader and maintainer of the Python script (which may or may not be your future self) to understand both Python and shell script. Remember the Python motto "explicit is better than implicit"; even when the Python code is going to be somewhat more complex than the equivalent (and often very terse) shell script, you might be better off removing the shell and replacing the functionality with native Python constructs. Minimizing the work done in an external process and keeping control within your own code as far as possible is often a good idea simply because it improves visibility and reduces the risks of -- wanted or unwanted -- side effects.

Wildcard expansion, variable interpolation, and redirection are all simple to replace with native Python constructs. A complex shell pipeline where parts or all cannot be reasonably rewritten in Python would be the one situation where perhaps you could consider using the shell. You should still make sure you understand the performance and security implications.

In the trivial case, to avoid shell=True, simply replace

subprocess.Popen("command -with -options 'like this' and\\ an\\ argument", shell=True)

with

subprocess.Popen(['command', '-with','-options', 'like this', 'and an argument'])

Notice how the first argument is a list of strings to pass to execvp(), and how quoting strings and backslash-escaping shell metacharacters is generally not necessary (or useful, or correct). Maybe see also When to wrap quotes around a shell variable?

If you don't want to figure this out yourself, the shlex.split() function can do this for you. It's part of the Python standard library, but of course, if your shell command string is static, you can just run it once, during development, and paste the result into your script.

As an aside, you very often want to avoid Popen if one of the simpler wrappers in the subprocess package does what you want. If you have a recent enough Python, you should probably use subprocess.run.

• With check=True it will fail if the command you ran failed.
• With stdout=subprocess.PIPE it will capture the command's output.
• With text=True (or somewhat obscurely, with the synonym universal_newlines=True) it will decode output into a proper Unicode string (it's just bytes in the system encoding otherwise, on Python 3).

If not, for many tasks, you want check_output to obtain the output from a command, whilst checking that it succeeded, or check_call if there is no output to collect.

I'll close with a quote from David Korn: "It's easier to write a portable shell than a portable shell script." Even subprocess.run('echo "$HOME"', shell=True) is not portable to Windows.

Perhaps the question needs to be slightly more precise here about what is required because it can be read it two different ways. i.e.

1. How do I get the structure/definition for a table in mysql?
2. How do I get the name of the schema/database this table resides in?

Given the accepted answer, the OP clearly intended it to be interpreted the first way. For anybody reading the question the other way try

SELECT `table_schema` 
FROM `information_schema`.`tables` 
WHERE `table_name` = 'whatever';

To call the method, you need to qualify function with self.. In addition to that, if you want to pass a filename, add a filename parameter (or other name you want).

class MyHandler(FileSystemEventHandler):

    def on_any_event(self, event):
        srcpath = event.src_path
        print (srcpath, 'has been ',event.event_type)
        print (datetime.datetime.now())
        filename = srcpath[12:]
        self.dropbox_fn(filename) # <----

    def dropbox_fn(self, filename):  # <-----
        print('In dropbox_fn:', filename)

Add all your objects to the TreeSet, you will get a sorted Set. Below is a raw example.

HashSet myHashSet = new HashSet();
myHashSet.add(1);
myHashSet.add(23);
myHashSet.add(45);
myHashSet.add(12);

TreeSet myTreeSet = new TreeSet();
myTreeSet.addAll(myHashSet);
System.out.println(myTreeSet); // Prints [1, 12, 23, 45]

The reason for using dictionaries in the first place is performance. Although it is correct that you can use named vectors and lists for the task the issue is that they are becoming quite slow and memory hungry with more data.

Yet what many people don't know is that R has indeed an inbuilt dictionary data structure: environments with the option hash = TRUE

See the following example for how to make it work:

# vectorize assign, get and exists for convenience
assign_hash <- Vectorize(assign, vectorize.args = c("x", "value"))
get_hash <- Vectorize(get, vectorize.args = "x")
exists_hash <- Vectorize(exists, vectorize.args = "x")

# keys and values
key<- c("tic", "tac", "toe")
value <- c(1, 22, 333)

# initialize hash
hash = new.env(hash = TRUE, parent = emptyenv(), size = 100L)
# assign values to keys
assign_hash(key, value, hash)
## tic tac toe 
##   1  22 333
# get values for keys
get_hash(c("toe", "tic"), hash)
## toe tic 
## 333   1
# alternatively:
mget(c("toe", "tic"), hash)
## $toe
## [1] 333
## 
## $tic
## [1] 1
# show all keys
ls(hash)
## [1] "tac" "tic" "toe"
# show all keys with values
get_hash(ls(hash), hash)
## tac tic toe 
##  22   1 333
# remove key-value pairs
rm(list = c("toe", "tic"), envir = hash)
get_hash(ls(hash), hash)
## tac 
##  22
# check if keys are in hash
exists_hash(c("tac", "nothere"), hash)
##     tac nothere 
##    TRUE   FALSE
# for single keys this is also possible:
# show value for single key
hash[["tac"]]
## [1] 22
# create new key-value pair
hash[["test"]] <- 1234
get_hash(ls(hash), hash)
##  tac test 
##   22 1234
# update single value
hash[["test"]] <- 54321
get_hash(ls(hash), hash)
##   tac  test 
##    22 54321

Edit: On the basis of this answer I wrote a blog post with some more context: http://blog.ephorie.de/hash-me-if-you-can

A really nice way to implement an isUTF8-function can be found on php.net:

function isUTF8($string) {
    return (utf8_encode(utf8_decode($string)) == $string);
}

React.createClass method has been deprecated in the new version of React, you can do it very simply in the following way make one functional component and another class component to maintain state:

Parent:

const ParentComp = () => {_x000D_
  _x000D_
  getLanguage = (language) => {_x000D_
    console.log('Language in Parent Component: ', language);_x000D_
  }_x000D_
  _x000D_
  <ChildComp onGetLanguage={getLanguage}_x000D_
};

Child:

class ChildComp extends React.Component {_x000D_
    state = {_x000D_
      selectedLanguage: ''_x000D_
    }_x000D_
    _x000D_
    handleLangChange = e => {_x000D_
        const language = e.target.value;_x000D_
        thi.setState({_x000D_
          selectedLanguage = language;_x000D_
        });_x000D_
        this.props.onGetLanguage({language}); _x000D_
    }_x000D_
_x000D_
    render() {_x000D_
        const json = require("json!../languages.json");_x000D_
        const jsonArray = json.languages;_x000D_
        const selectedLanguage = this.state;_x000D_
        return (_x000D_
            <div >_x000D_
                <DropdownList ref='dropdown'_x000D_
                    data={jsonArray} _x000D_
                    value={tselectedLanguage}_x000D_
                    caseSensitive={false} _x000D_
                    minLength={3}_x000D_
                    filter='contains'_x000D_
                    onChange={this.handleLangChange} />_x000D_
            </div>            _x000D_
        );_x000D_
    }_x000D_
};

Credit to @wjandrea for dict.fromdict method idea:

def solve(arr): 
    return list(dict.fromkeys(arr[::-1]))[::-1]

This will reverse input and output to iterate properly

The method which you are using is rendering login button from the Facebook Javascript code. However, you can write your own Javascript code function to mimic the functionality. Here is how to do it -

1. Create a simple anchor tag link with the image you want to show. Have a onclick method on anchor tag which would actually do the real job.

<a href="#" onclick="fb_login();"><img src="images/fb_login_awesome.jpg" border="0" alt=""></a>

2. Next, we create the Javascript function which will show the actual popup and will fetch the complete user information, if user allows. We also handle the scenario if user disallows our facebook app.

window.fbAsyncInit = function() {
    FB.init({
        appId   : 'YOUR_APP_ID',
        oauth   : true,
        status  : true, // check login status
        cookie  : true, // enable cookies to allow the server to access the session
        xfbml   : true // parse XFBML
    });

  };

function fb_login(){
    FB.login(function(response) {

        if (response.authResponse) {
            console.log('Welcome!  Fetching your information.... ');
            //console.log(response); // dump complete info
            access_token = response.authResponse.accessToken; //get access token
            user_id = response.authResponse.userID; //get FB UID

            FB.api('/me', function(response) {
                user_email = response.email; //get user email
          // you can store this data into your database             
            });

        } else {
            //user hit cancel button
            console.log('User cancelled login or did not fully authorize.');

        }
    }, {
        scope: 'public_profile,email'
    });
}
(function() {
    var e = document.createElement('script');
    e.src = document.location.protocol + '//connect.facebook.net/en_US/all.js';
    e.async = true;
    document.getElementById('fb-root').appendChild(e);
}());

3. We are done.

Please note that the above function is fully tested and works. You just need to put your facebook APP ID and it will work.

Try this: It works in any case, if the file doesn't exists, it will create it and then write to it. And if already exists, no problem it will open and write to it :

 using (FileStream fs= new FileStream(@"File.txt",FileMode.Create,FileAccess.ReadWrite))
 { 
   fs.close();
 }
 using (StreamWriter sw = new StreamWriter(@"File.txt")) 
 { 
   sw.WriteLine("bla bla bla"); 
   sw.Close(); 
 } 

I think your assignment is backwards:

a[i] = b[i];

should be:

b[i] = a[i];

There are several approaches.

One is to use a non-capturing group in the regex: (?:/(?P<title>[a-zA-Z]+)/)?
Making a Regex Django URL Token Optional

Another, easier to follow way is to have multiple rules that matches your needs, all pointing to the same view.

urlpatterns = patterns('',
    url(r'^project_config/$', views.foo),
    url(r'^project_config/(?P<product>\w+)/$', views.foo),
    url(r'^project_config/(?P<product>\w+)/(?P<project_id>\w+)/$', views.foo),
)

Keep in mind that in your view you'll also need to set a default for the optional URL parameter, or you'll get an error:

def foo(request, optional_parameter=''):
    # Your code goes here

There is no such thing as Xand or Xnot. There is Nand, which is the opposite of and

TRUE and TRUE   : TRUE
TRUE and FALSE  : FALSE
FALSE and TRUE  : FALSE
FALSE and FALSE : FALSE


TRUE nand TRUE   : FALSE
TRUE nand FALSE  : TRUE
FALSE nand TRUE  : TRUE
FALSE nand FALSE : TRUE

Best command is: tree -fi

-f print the full path prefix for each file
-i don't print indentations

e.g.

$ tree -fi
.
./README.md
./node_modules
./package.json
./src
./src/datasources
./src/datasources/bookmarks.js
./src/example.json
./src/index.js
./src/resolvers.js
./src/schema.js

In order to use the files but not the links, you have to remove > from your output:

tree -fi |grep -v \>

If you want to know the nature of each file, (to read only ASCII files for example) with two whiles:

tree -fi | \
grep -v \> | \
while read first ; do 
    file ${first}
done | \
while read second; do 
    echo ${second} | grep ASCII
done

If your variable is an argument, you can simply use %~dpn (for paths) or %~n (for names only) followed by the argument number, so you don't have to worry for varying extension lengths.

For instance %~dpn0 will return the path of the batch file without its extension, %~dpn1 will be %1 without extension, etc.

Whereas %~n0 will return the name of the batch file without its extension, %~n1 will be %1 without path and extension, etc.

We can do this by using request.query_string.

Example:

Lets consider view.py

from my_script import get_url_params

@app.route('/web_url/', methods=('get', 'post'))
def get_url_params_index():
    return Response(get_url_params())

You also make it more modular by using Flask Blueprints - https://flask.palletsprojects.com/en/1.1.x/blueprints/

Lets consider first name is being passed as a part of query string /web_url/?first_name=john

## here is my_script.py

## import required flask packages
from flask import request
def get_url_params():
    ## you might further need to format the URL params through escape.    
    firstName = request.args.get('first_name') 
    return firstName
    

As you see this is just a small example - you can fetch multiple values + formate those and use it or pass it onto the template file.

Using JSON.stringify(data);:

$.ajax({
    url: ...
    success:function(data){
        JSON.stringify(data); //to string
        alert(data.you_value); //to view you pop up
    }
});

I tried all the fixes - taking databases offline and then bringing them online, installed Cumulative update 10, repaired SQL Server Installation, refreshed local cache, made changes to the required settings on SQL Server Management Studio but everything was in vain. Finally installing the correct service pack (SP1) did the trick for me !

Follow the link below, and download SQLServer2008R2SP1-KB2528583-x86-ENU.exe (or the x64 file for a x64 bit instance of SQL Server)

Finally i have Intellisense enabled !

You can do this with a pivot table and add a line with the pourcentage for each category like brettdj showed in his answer. But if you want to keep your data as it is, there is a solution by using some javascript.

Javascript is a powerful language offering a lot of useful data visualization libraries like plotly.js.

Here is a working code I have written for you:

https://www.funfun.io/1/#/edit/5a58c6368dfd67466879ed27

In this example, I use a Json file to get the data from the embedded spreadsheet, so I can use it in my javascript code and create a bar chart.

I calculate the percentage by adding the values of all the category present in the table and using this formula (you can see it in the script.js file): Percentage (%) = 100 x partial value / total value

It automatically calculates the total and pourcentage even if you add more categories.

I used plotly.js to create my chart, it has a good documentation and lots of examples for beginners, this code gets all the option you want to use:

var trace1 = {
    x: xValue, 
    y: data,
    type: 'bar',
    text: yValue,
    textposition: 'auto',
    hoverinfo: 'none',
    marker: {
    color: 'yellow',
    opacity: 0.6,
    line: {
      color: 'yellow',
      width: 1.5
    }
  }
};

It is rather self explanatory, the text is where you put the percentage.

Once you've made your chart you can load it in excel by passing the URL in the Funfun add-in. Here is how it looks like with my example:

I know it is an old post but I hope it helps people with the same problem !

If you don't have an existing local branch, it is truly as simple as:

git fetch
git checkout <remote-branch-name>

For instance if you fetch and there is a new remote tracking branch called origin/feature/Main_Page, just do this:

git checkout feature/Main_Page

This creates a local branch with the same name as the remote branch, tracking that remote branch. If you have multiple remotes with the same branch name, you can use the less ambiguous:

git checkout -t <remote>/<remote-branch-name>

If you already made the local branch and don't want to delete it, see How do you make an existing Git branch track a remote branch?.

Open the file again using vi. and then press " i " or press insert key ,

For save and quit

  Enter Esc    

and write the following command

For those using the Symfony framework, the phpseclib can also be used to connect via SSH. It can be installed using composer:

composer require phpseclib/phpseclib

Next, simply use it as follows:

use phpseclib\Net\SSH2;

// Within a controller for example:
$ssh = new SSH2('hostname or ip');
if (!$ssh->login('username', 'password')) {
    // Login failed, do something
}

$return_value = $ssh->exec('command');

This is a crazy thing of apple. When you say self.navigationItem.rightBarButtonItem.title then it will say nil while on the GUI it shows Edit or Save. Fresher likes me will take a lot of time to debug this behavior.

There is a requirement that the Item will show Edit in the firt load then user taps on it It will change to Save title. To archive this, i did as below.

//view did load will say Edit title

private func loadRightBarItem() {
    let logoutBarButtonItem = UIBarButtonItem(title: "Edit", style: .done, target: self, action: #selector(handleEditBtn))
    self.navigationItem.rightBarButtonItem  = logoutBarButtonItem
}

// tap Edit item will change to Save title

@objc private func handleEditBtn() {
    print("clicked on Edit btn")
    let logoutBarButtonItem = UIBarButtonItem(title: "Save", style: .done, target: self, action: #selector(handleSaveBtn))
    self.navigationItem.rightBarButtonItem  = logoutBarButtonItem
    blockEditTable(isBlock: false)
}

//tap Save item will display Edit title

@objc private func handleSaveBtn(){
    print("clicked on Save btn")
    let logoutBarButtonItem = UIBarButtonItem(title: "Edit", style: .done, target: self, action: #selector(handleEditBtn))
    self.navigationItem.rightBarButtonItem  = logoutBarButtonItem

    saveInvitation()
    blockEditTable(isBlock: true)

}

The date, datetime, and time objects all support a strftime(format) method, to create a string representing the time under the control of an explicit format string.

Here is a list of the format codes with their directive and meaning.

    %a  Locale’s abbreviated weekday name.
    %A  Locale’s full weekday name.      
    %b  Locale’s abbreviated month name.     
    %B  Locale’s full month name.
    %c  Locale’s appropriate date and time representation.   
    %d  Day of the month as a decimal number [01,31].    
    %f  Microsecond as a decimal number [0,999999], zero-padded on the left
    %H  Hour (24-hour clock) as a decimal number [00,23].    
    %I  Hour (12-hour clock) as a decimal number [01,12].    
    %j  Day of the year as a decimal number [001,366].   
    %m  Month as a decimal number [01,12].   
    %M  Minute as a decimal number [00,59].      
    %p  Locale’s equivalent of either AM or PM.
    %S  Second as a decimal number [00,61].
    %U  Week number of the year (Sunday as the first day of the week)
    %w  Weekday as a decimal number [0(Sunday),6].   
    %W  Week number of the year (Monday as the first day of the week)
    %x  Locale’s appropriate date representation.    
    %X  Locale’s appropriate time representation.    
    %y  Year without century as a decimal number [00,99].    
    %Y  Year with century as a decimal number.   
    %z  UTC offset in the form +HHMM or -HHMM.
    %Z  Time zone name (empty string if the object is naive).    
    %%  A literal '%' character.

This is what we can do with the datetime and time modules in Python

    import time
    import datetime

    print "Time in seconds since the epoch: %s" %time.time()
    print "Current date and time: ", datetime.datetime.now()
    print "Or like this: ", datetime.datetime.now().strftime("%y-%m-%d-%H-%M")


    print "Current year: ", datetime.date.today().strftime("%Y")
    print "Month of year: ", datetime.date.today().strftime("%B")
    print "Week number of the year: ", datetime.date.today().strftime("%W")
    print "Weekday of the week: ", datetime.date.today().strftime("%w")
    print "Day of year: ", datetime.date.today().strftime("%j")
    print "Day of the month : ", datetime.date.today().strftime("%d")
    print "Day of week: ", datetime.date.today().strftime("%A")

That will print out something like this:

    Time in seconds since the epoch:    1349271346.46
    Current date and time:              2012-10-03 15:35:46.461491
    Or like this:                       12-10-03-15-35
    Current year:                       2012
    Month of year:                      October
    Week number of the year:            40
    Weekday of the week:                3
    Day of year:                        277
    Day of the month :                  03
    Day of week:                        Wednesday

YOur best bet is to fix the datbase design and add the identioty column to the table. Why do you havea table without one in the first place? Especially one with duplicate records! Clearly the database itself needs redesigning.

And why do you have to have this in a view, why isn't your solution with the temp table a valid solution? Views are not usually a really good thing to do to a perfectly nice database.

Because equal is a function derived from Object class, this function compares items of the class. if you use it with null it will return false cause cause class content is not null. In addition == compares reference to an object.

If your element is not directly on you scene go back to Parent to remove it

  function removeEntity(object) {
        var selectedObject = scene.getObjectByName(object.name);
        selectedObject.parent.remove( selectedObject );
    }

It's possibly a 32 - 64 bits mismatch.

If you're running on a 64-bit OS, the Assembly RevitAPI may be compiled as 32-bit and your process as 64-bit or "Any CPU".

Or, the RevitAPI is compiled as 64-bit and your process is compiled as 32-bit or "Any CPU" and running on a 32-bit OS.

To change DNS to automatic via command, you can run the following command:

The answer to my comment above on the Original Question makes me think this is all he wants:

loopnum = 0
word = 'afrykanerskojezyczny'
wordlist = ['afrykanerskojezycznym','afrykanerskojezyczni','nieafrykanerskojezyczni']
for i in wordlist:
    wordlist[loopnum] = word
    loopnum += 1

This will do the following:

For every value in wordlist, set that value of the wordlist to the origional code.

All you have to do is put this piece of code where you need to change wordlist, making sure you store the words you need to change in wordlist, and that the original word is correct.

Hope this helps!

Ternary Operator is basically shorthand for if/else statement. We can use to reduce few lines of code and increases readability.

Your code looks cleaner to me. But we can add more cleaner way as follows-

$test = (empty($address['street2'])) ? 'Yes <br />' : 'No <br />';

Another way-

$test = ((empty($address['street2'])) ? 'Yes <br />' : 'No <br />');

Note- I have added bracket to whole expression to make it cleaner. I used to do this usually to increase readability. With PHP7 we can use Null Coalescing Operator / php 7 ?? operator for better approach. But your requirement it does not fit.

Step1: Delete all instances of java from you machine

Step2: Delete all the environment variables related to java/jdk/jre

Step3: Check in programm files and program files(X86) folder, there should not be java folder.

Step4: Install java again.

Step5: Go to cmd and type "java -version" Result: it will display the java version which is installed in your machine.

Step6: now delete all the files which are in C:/User/AdminOrUserNameofYourMachine/.m2 folder

Step6: go to cmd and run "mvn -v" Result: It will display the Apache maven version installed on your machine

Step7: Now Rebuild your project.

This worked for me.

Try this:

$month = ( isset($_POST['month']) ) ? $_POST['month'] : '';

$op = ( isset($_POST['op']) ) ? $_POST['op'] : '';

I agree and found this file under xammp-control the type of file is configuration. When I changed it to 8080 it worked automagically!

Kind of an anonymous lookup table rather than a long switch statement:

return (const char *[]) {
    "bananas & monkeys",
    "Round and orange", 
    "APPLE",
}[enumVal];

if(isset($_POST['submit']))
   {  
 if(!empty($_POST['login_username']) && !empty($_POST['login_password']))
    {
     $uname = $_POST['login_username'];
     $pass = $_POST['login_password'];
     $res="SELECT count(*),uname,role FROM users WHERE uname='$uname' and  password='$pass' ";
$query=mysql_query($res)or die (mysql_error());  

list($result,$uname,$role) = mysql_fetch_row($query);   
$_SESSION['username'] = $uname;
$_SESSION['role'] = $role;
 if(isset($_SESSION['username']) && $_SESSION['role']=="admin")
 {
 if($result>0)
      {
       header ('Location:Dashboard.php');
      }
      else
      {
         header ('Location:loginform.php');
      }
 }

Try this code for disabling inspect element option

        if (e.keyCode == 123 || e.keyCode == 18) {
            return false
        }
    };

    document.oncontextmenu = function(e) {
        var t = e || window.event;
        var n = t.target || t.srcElement;
        if (n.nodeName != "A") return false
    };
    document.ondragstart = function() {
        return false
    };
});

Check if a program exists from a Bash script covers this very well. In any shell script, you're best off running command -v $command_name for testing if $command_name can be run. In bash you can use hash $command_name, which also hashes the result of any path lookup, or type -P $binary_name if you only want to see binaries (not functions etc.)

Caveat Emptor - Destructive commands ahead.

Mitigation - git reflog can save you if you need it.

1) UNDO local file changes and KEEP your last commit

git reset --hard

2) UNDO local file changes and REMOVE your last commit

git reset --hard HEAD^

3) KEEP local file changes and REMOVE your last commit

git reset --soft HEAD^

For anyone that simply are looking to bypass the ERROR page to display the content on shared hosting. You might wanna try and use redirect in .htaccess file. If it is say 406 error, on UnoEuro it didn't seem to work simply deactivating the security. So I used this instead:

ErrorDocument 406 /

Then you can always change the error status using PHP. But be aware that in my case doing so means I am opening a door to SQL injections as I am bypassing WAF. So you will need to make sure that you either have your own security measures or enable the security again asap.

For the above code to function; you need to make sure the following directories exist (mine didn't). Just add the following to a bat and run it:

mkdir C:\Windows\System32\GroupPolicy\Machine\Scripts\Startup
mkdir C:\Windows\System32\GroupPolicy\Machine\Scripts\Shutdown
mkdir C:\Windows\System32\GroupPolicy\User\Scripts\Startup
mkdir C:\Windows\System32\GroupPolicy\User\Scripts\Shutdown

It's just that GP needs those directories to exist for:

Group Policy\Local Computer Policy\Windows Settings\Scripts (Startup/Shutdown)

to function properly.

You have to explicitly cast the string types to the same in order to concatenate them, In your case you may solve the issue by simply addig an 'N' in front of 'SomeText' (N'SomeText'). If that doesn't work, try Cast('SomeText' as nvarchar(8)).

My app manage a lot of images and it died with a OutOfMemoryError. This helped me. In the Manifest.xml Add

<application
....
   android:largeHeap="true"> 

It does not matter where the variable comes from. Main thing we have one ... Set the variable name between square brackets "[ .. ]".

var optionName = 'nameA';
var JsonVar = {
[optionName] : 'some value'
}

You can not change the REFERRER property. What you are asking is to spoof the request.

Just in case you want the referrer to be set like you have opened a url directly or for the fist time{http referrer=null} then reload the page

location.reload();

You should look at the toggle function found on jQuery. This will allow you to specify an easing method to define how the toggle works.

slideToggle will only slide up and down, not left/right if that's what you are looking for.

If you need the class to be toggled as well you can deifine that in the toggle function with a:

$(this).closest('article').toggle('slow', function() {
    $(this).toggleClass('expanded');
});

• Basic Definition

TEXT and VarChar(MAX) are Non-Unicode large Variable Length character data type, which can store maximum of 2147483647 Non-Unicode characters (i.e. maximum storage capacity is: 2GB).

• Which one to Use?

As per MSDN link Microsoft is suggesting to avoid using the Text datatype and it will be removed in a future versions of Sql Server. Varchar(Max) is the suggested data type for storing the large string values instead of Text data type.

• In-Row or Out-of-Row Storage

Data of a Text type column is stored out-of-row in a separate LOB data pages. The row in the table data page will only have a 16 byte pointer to the LOB data page where the actual data is present. While Data of a Varchar(max) type column is stored in-row if it is less than or equal to 8000 byte. If Varchar(max) column value is crossing the 8000 bytes then the Varchar(max) column value is stored in a separate LOB data pages and row will only have a 16 byte pointer to the LOB data page where the actual data is present. So In-Row Varchar(Max) is good for searches and retrieval.

• Supported/Unsupported Functionalities

Some of the string functions, operators or the constructs which doesn’t work on the Text type column, but they do work on VarChar(Max) type column.

1. = Equal to Operator on VarChar(Max) type column

2. Group by clause on VarChar(Max) type column

   • System IO Considerations

As we know that the VarChar(Max) type column values are stored out-of-row only if the length of the value to be stored in it is greater than 8000 bytes or there is not enough space in the row, otherwise it will store it in-row. So if most of the values stored in the VarChar(Max) column are large and stored out-of-row, the data retrieval behavior will almost similar to the one that of the Text type column.

But if most of the values stored in VarChar(Max) type columns are small enough to store in-row. Then retrieval of the data where LOB columns are not included requires the more number of data pages to read as the LOB column value is stored in-row in the same data page where the non-LOB column values are stored. But if the select query includes LOB column then it requires less number of pages to read for the data retrieval compared to the Text type columns.

Conclusion

Use VarChar(MAX) data type rather than TEXT for good performance.

For those looking to control the space between a dynamic number of columns, try:

<div class="row no-gutters">
    <div class="col">
        <div class="inner">
            <!-- content here -->
        </div>
    </div>
    <div class="col">
        <div class="inner">
            <!-- content here -->
        </div>
    </div>
    <!-- etc. -->
</div>

CSS:

.col:not(:last-child) .inner {
  margin: 2px; // Or whatever you want your spacing to be
}

update tablename set coldate=DATE_ADD(coldate, INTERVAL 2 DAY)

userInfos.GroupBy(userInfo => userInfo.metric)
        .OrderBy(group => group.Key)
        .Select(group => Tuple.Create(group.Key, group.Count()));

Height lines converted into points and pixel (my own formula). Here is an example with a manual entry of 213.67 points in the Row Height field:

213.67  Manual Entry    
  0.45  Add 0.45    
214.12  Subtotal    
213.75  Round to a multiple of 0.75 
213.00  Subtract 0.75 provides manual entry converted by Excel  
284.00  Divide by 0.75 gives the number of pixels of height

Here the manual entry of 213.67 points gives 284 pixels.
Here the manual entry of 213.68 points gives 285 pixels.

(Why 0.45? I do not know but it works.)

Long.valueOf(String s) - obviously due care must be taken to protect against non-numbers if that is possible in your code.

One common cause of a variable not existing after an HTML form has been submitted is the form element is not contained within a <form> tag:

Example: Element not contained within the <form>

<form action="example.php" method="post">
    <p>
        <input type="text" name="name" />
        <input type="submit" value="Submit" />
    </p>
</form>

<select name="choice">
    <option value="choice1">choice 1</option>
    <option value="choice2">choice 2</option>
    <option value="choice3">choice 3</option>
    <option value="choice4">choice 4</option>
</select>

Example: Element now contained within the <form>

<form action="example.php" method="post">
    <select name="choice">
        <option value="choice1">choice 1</option>
        <option value="choice2">choice 2</option>
        <option value="choice3">choice 3</option>
        <option value="choice4">choice 4</option>
    </select>
    <p>
        <input type="text" name="name" />
        <input type="submit" value="Submit" />
    </p>
</form>

As Mike stated, the best way is to use information_schema. As long as you're not in the master database, system stored procedures won't be returned.

SELECT * 
  FROM DatabaseName.INFORMATION_SCHEMA.ROUTINES
 WHERE ROUTINE_TYPE = 'PROCEDURE'

If for some reason you had non-system stored procedures in the master database, you could use the query (this will filter out MOST system stored procedures):

SELECT * 
  FROM [master].INFORMATION_SCHEMA.ROUTINES
 WHERE ROUTINE_TYPE = 'PROCEDURE' 
   AND LEFT(ROUTINE_NAME, 3) NOT IN ('sp_', 'xp_', 'ms_')

$("#dropdownList option[text='it\'s me']").attr("selected","selected"); 

Just for the record:

Ruby on Rails 4 application in OS X with PostgresApp (in this case 0.17.1 version needed - kind of an old project):

gem install pg -v '0.17.1' -- --with-pg-config=/Applications/Postgres.app/Contents/Versions/9.3/bin/pg_config

How host name verification should be done is defined in RFC 6125, which is quite recent and generalises the practice to all protocols, and replaces RFC 2818, which was specific to HTTPS. (I'm not even sure Java 7 uses RFC 6125, which might be too recent for this.)

From RFC 2818 (Section 3.1):

If a subjectAltName extension of type dNSName is present, that MUST be used as the identity. Otherwise, the (most specific) Common Name field in the Subject field of the certificate MUST be used. Although the use of the Common Name is existing practice, it is deprecated and Certification Authorities are encouraged to use the dNSName instead.

[...]

In some cases, the URI is specified as an IP address rather than a hostname. In this case, the iPAddress subjectAltName must be present in the certificate and must exactly match the IP in the URI.

Essentially, the specific problem you have comes from the fact that you're using IP addresses in your CN and not a host name. Some browsers might work because not all tools follow this specification strictly, in particular because "most specific" in RFC 2818 isn't clearly defined (see discussions in RFC 6215).

If you're using keytool, as of Java 7, keytool has an option to include a Subject Alternative Name (see the table in the documentation for -ext): you could use -ext san=dns:www.example.com or -ext san=ip:10.0.0.1.

EDIT:

You can request a SAN in OpenSSL by changing openssl.cnf (it will pick the copy in the current directory if you don't want to edit the global configuration, as far as I remember, or you can choose an explicit location using the OPENSSL_CONF environment variable).

Set the following options (find the appropriate sections within brackets first):

[req]
req_extensions = v3_req

[ v3_req ]
subjectAltName=IP:10.0.0.1
# or subjectAltName=DNS:www.example.com

There's also a nice trick to use an environment variable for this (rather in than fixing it in a configuration file) here: http://www.crsr.net/Notes/SSL.html

PUT ing

PUT /binders/{id}/docs Create or update, and relate a single document to a binder

e.g.:

PUT /binders/1/docs HTTP/1.1
{
  "docNumber" : 1
}

PATCH ing

PATCH /docs Create docs if they do not exist and relate them to binders

e.g.:

PATCH /docs HTTP/1.1
[
    { "op" : "add", "path" : "/binder/1/docs", "value" : { "doc_number" : 1 } },
    { "op" : "add", "path" : "/binder/8/docs", "value" : { "doc_number" : 8 } },
    { "op" : "add", "path" : "/binder/3/docs", "value" : { "doc_number" : 6 } }
] 

I'll include additional insights later, but in the meantime if you want to, have a look at RFC 5789, RFC 6902 and William Durand's Please. Don't Patch Like an Idiot blog entry.

Android Q broke most of these for me. Here's a new one that seems to be working (at least on Android Q).

adb shell "dumpsys activity activities | grep mResumedActivity"

Output looks like:

mResumedActivity: ActivityRecord{7f6df99 u0 com.sample.app/.feature.SampleActivity t92}

Edit: Works on Android R for me as well

Iv'd found 2 solutions to the problem, which its implied that you detect touch with modernizr or something else and set a touch class on the html element.

This is good but not supported very well:

html.touch *:hover {
    all:unset!important;
}

But this has a very good support:

html.touch *:hover {
    pointer-events: none !important;
}

Works flawless for me, it makes all the hover effects be like when you have a touch on a button it will light up but not end up buggy as the initial hover effect for mouse events.

Detecting touch from no-touch devices i think modernizr has done the best job:

https://github.com/Modernizr/Modernizr/blob/master/feature-detects/touchevents.js

EDIT

I found a better and simpler solution to this issue

How to determine if the client is a touch device

You can do one of the following:

<?php
    $data = 'My data';

    function menugen() {
        global $data;
        echo "[" . $data . "]";
    }

    menugen();

Or

<?php
    $data = 'My data';

    function menugen() {
        echo "[" . $GLOBALS['data'] . "]";
    }

    menugen();

That being said, overuse of globals can lead to some poor code. It is usually better to pass in what you need. For example, instead of referencing a global database object you should pass in a handle to the database and act upon that. This is called dependency injection. It makes your life a lot easier when you implement automated testing (which you should).

A more generic solution for might be the following.

    extendDf <- function (df, n) {
    withFactors <- sum(sapply (df, function(X) (is.factor(X)) )) > 0
    nr          <- nrow (df)
    colNames    <- names(df)
    for (c in 1:length(colNames)) {
        if (is.factor(df[,c])) {
            col         <- vector (mode='character', length = nr+n) 
            col[1:nr]   <- as.character(df[,c])
            col[(nr+1):(n+nr)]<- rep(col[1], n)  # to avoid extra levels
            col         <- as.factor(col)
        } else {
            col         <- vector (mode=mode(df[1,c]), length = nr+n)
            class(col)  <- class (df[1,c])
            col[1:nr]   <- df[,c] 
        }
        if (c==1) {
            newDf       <- data.frame (col ,stringsAsFactors=withFactors)
        } else {
            newDf[,c]   <- col 
        }
    }
    names(newDf) <- colNames
    newDf
}

The function extendDf() extends a data frame with n rows.

As an example:

aDf <- data.frame (l=TRUE, i=1L, n=1, c='a', t=Sys.time(), stringsAsFactors = TRUE)
extendDf (aDf, 2)
#      l i n c                   t
# 1  TRUE 1 1 a 2016-07-06 17:12:30
# 2 FALSE 0 0 a 1970-01-01 01:00:00
# 3 FALSE 0 0 a 1970-01-01 01:00:00

system.time (eDf <- extendDf (aDf, 100000))
#    user  system elapsed 
#   0.009   0.002   0.010
system.time (eDf <- extendDf (eDf, 100000))
#    user  system elapsed 
#   0.068   0.002   0.070

I am not sure if this is efficient, but this is one of the possible ways:

Read json from url use url.openStream() and read contents into a string.

construct a JSON object with this string (more at json.org)

JSONObject(java.lang.String source)
      Construct a JSONObject from a source JSON text string.

Just as a small addition, you can also do an apply if you have a complex function that you apply to a single column:

http://pandas.pydata.org/pandas-docs/dev/generated/pandas.DataFrame.apply.html

df[b] = df[a].apply(lambda col: do stuff with col here)

You can create a string[] (string array) that contains your string like :

string someString = "something";
string[] stringArray = new string[]{ someString };

The variable stringArray will now have a length of 1 and contain someString.
