A DATE value per the SQL standard is YYYY-MM-DD. So even though Oracle stores the time information, my guess is that they're displaying the value in a way that is compatible with the SQL standard. In the standard, there is the TIMESTAMP data type that includes date and time info.

You might want to take a look at the excellent HTTP Python library called Requests. It makes every task involving HTTP a bit easier than urllib2. From Cookies section of quickstart guide:

To send your own cookies to the server, you can use the cookies parameter:

>>> cookies = dict(cookies_are='working')

>>> r = requests.get('http://httpbin.org/cookies', cookies=cookies)
>>> r.text
'{"cookies": {"cookies_are": "working"}}'

SET @@local.net_read_timeout=360;

Warning: The following will not work when you are applying it in remote connection:

SET @@global.net_read_timeout=360;

I have tried the following config for eclipse.ini:

org.eclipse.epp.package.jee.product
--launcher.defaultAction
openFile
--launcher.XXMaxPermSize
1024M
-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
1024m
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vmargs
-Dosgi.requiredJavaVersion=1.6
-Xms128m
-Xmx2048m

Now eclipse performance is about 2 times faster then before.

You can also find a good help ref here: http://help.eclipse.org/indigo/index.jsp?topic=/org.eclipse.platform.doc.isv/reference/misc/runtime-options.html

try: typeof(predQuery[preId])=='undefined'
or more generally: typeof(yourArray[yourIndex])=='undefined'
You're comparing "undefined" to undefined, which returns false =)

string.Format("{0}", myObj);

string.Format will format null as an empty string and call ToString() on non-null objects. As I understand it, this is what you were looking for.

Technically, JSP are all converted to Servlets during runtime.

JSP was initially created for the purpose of the decoupling the business logic and the design logic, following the MVC pattern. So JSP is technically all Java code during runtime.

But to answer the question, tag libraries are usually used for applying logic (removing Java code) to JSP pages.

For errors like this you should involve oracle support. Unfortunately you do not mention what oracle release you are using. The error can be related to optimizer bind peeking. Depending on the oracle version different workarounds apply.

You have two ways to address this:

• upgrade to 11.2
• set oracle parameter _optim_peek_user_binds = false

Of course underscore parameters should only be set if advised by oracle support

URL-encoded payload must be provided on the body parameter of the http.NewRequest(method, urlStr string, body io.Reader) method, as a type that implements io.Reader interface.

Based on the sample code:

package main

import (
    "fmt"
    "net/http"
    "net/url"
    "strconv"
    "strings"
)

func main() {
    apiUrl := "https://api.com"
    resource := "/user/"
    data := url.Values{}
    data.Set("name", "foo")
    data.Set("surname", "bar")

    u, _ := url.ParseRequestURI(apiUrl)
    u.Path = resource
    urlStr := u.String() // "https://api.com/user/"

    client := &http.Client{}
    r, _ := http.NewRequest(http.MethodPost, urlStr, strings.NewReader(data.Encode())) // URL-encoded payload
    r.Header.Add("Authorization", "auth_token=\"XXXXXXX\"")
    r.Header.Add("Content-Type", "application/x-www-form-urlencoded")
    r.Header.Add("Content-Length", strconv.Itoa(len(data.Encode())))

    resp, _ := client.Do(r)
    fmt.Println(resp.Status)
}

resp.Status is 200 OK this way.

You can use the :not filter selector:

$('foo:not(".someClass")')

Or not() method:

$('foo').not(".someClass")

More Info:

• http://api.jquery.com/not-selector/
• http://api.jquery.com/not/

Try this:

<?php
$to = "[email protected]";
$subject = "My subject";
$txt = "Hello world!";
$headers = "From: [email protected]" . "\r\n" .
"CC: [email protected]";

mail($to,$subject,$txt,$headers);
?>

In this particular case the clearest solution is the S.Lott answer

But in some complex logical conditions I would prefer use some boolean algebra to get a clear solution.

Using De Morgan's law ¬(A^B) = ¬Av¬B

not (u0 <= u and u < u0+step)
(not u0 <= u) or (not u < u0+step)
u0 > u or u >= u0+step

then

if u0 > u or u >= u0+step:
    pass

... in this case the «clear» solution is not more clear :P

Write multi-line text with environment variables using echo:

echo -e "
Home Directory: $HOME \n
hello world 1 \n
hello world 2 \n
line n... \n
" > file.txt 

Gathering the code in the answers, I wrote this function that seems running well on my FF 25.

function CCSStylesheetRuleStyle(stylesheet, selectorText, style, value){
  /* returns the value of the element style of the rule in the stylesheet
  *  If no value is given, reads the value
  *  If value is given, the value is changed and returned
  *  If '' (empty string) is given, erases the value.
  *  The browser will apply the default one
  *
  * string stylesheet: part of the .css name to be recognized, e.g. 'default'
  * string selectorText: css selector, e.g. '#myId', '.myClass', 'thead td'
  * string style: camelCase element style, e.g. 'fontSize'
  * string value optionnal : the new value
  */
  var CCSstyle = undefined, rules;
  for(var m in document.styleSheets){
    if(document.styleSheets[m].href.indexOf(stylesheet) != -1){
     rules = document.styleSheets[m][document.all ? 'rules' : 'cssRules'];
     for(var n in rules){
       if(rules[n].selectorText == selectorText){
         CCSstyle = rules[n].style;
         break;
       }
     }
     break;
    }
  }
  if(value == undefined)
    return CCSstyle[style]
  else
    return CCSstyle[style] = value
}

This is a way to put values in the css that will be used in JS even if not understood by the browser. e.g. maxHeight for a tbody in a scrolled table.

Call :

CCSStylesheetRuleStyle('default', "#mydiv", "height");

CCSStylesheetRuleStyle('default', "#mydiv", "color", "#EEE");

I think you already solved this problem, and as other answers suggested

android:background="@drawable/eye"

is available. But I prefer

android:src="@drawable/eye"
android:background="00000000" // transparent

and it works well too.(of course former code will set image as a background and the other will set image as a image) But according to your selected answer, I guess you meant 9-patch.

Here is a jQuery plugin that does exactly that: http://fixedheadertable.com/

Usage:

$('selector').fixedHeaderTable({ fixedColumn: 1 });

Set the fixedColumn option if you want any number of columns to be also fixed for horizontal scrolling.

EDIT: This example http://www.datatables.net/examples/basic_init/scroll_y.html is much better in my opinion, although with DataTables you'll need to get a better understanding of how it works in general.

EDIT2: For Bootstrap to work with DataTables you need to follow the instructions here: http://datatables.net/blog/Twitter_Bootstrap_2 (I have tested this and it works)- For Bootstrap 3 there's a discussion here: http://datatables.net/forums/discussion/comment/53462 - (I haven't tested this)

Procedure to get Python Working in XCode 7

Step 1: Setup your Project with a External Build System

Step 1.1: Edit the Project Scheme

Step 2: Specify Python as the executable for the project (shift-command-g) the path should be /usr/bin/python

Step 3: Specify your custom working directory

Step 4: Specify your command line arguments to be the name of your python file. (in this example "test.py")

Step 5: Thankfully thats it!

(debugging can't be added until OSX supports a python debugger?)

This is a CORS issue. There are some settings you can change in angular - these are the ones I typically set in the Angular .config method (not all are related to CORS):

$httpProvider.defaults.useXDomain = true;
$httpProvider.defaults.withCredentials = true;
delete $httpProvider.defaults.headers.common["X-Requested-With"];
$httpProvider.defaults.headers.common["Accept"] = "application/json";
$httpProvider.defaults.headers.common["Content-Type"] = "application/json";

You also need to configure your webservice - the details of this will depend on the server side language you are using. If you use a network monitoring tool you will see it sends an OPTIONS request initially. Your server needs to respond appropriately to allow the CORS request.

The reason it works in your brower is because it isn't make a cross-origin request - whereas your Angular code is.

Making use of CSS sprites and data uri gives extra interesting benefits like fast loading and less requests AND we get IE8 support by using image/base64:

Codepen sample using SVG

HTML

<div class="div1"></div>
<div class="div2"></div>

CSS

.div1:after, .div2:after {
  content: '';
  display: block;
  height: 80px;
  width: 80px;
  background-image: url(data:image/svg+xml,%3Csvg%20xmlns%3D%22http%3A%2F%2Fwww.w3.org%2F2000%2Fsvg%22%20version%3D%221.1%22%20height%3D%2280%22%20width%3D%22160%22%3E%0D%0A%20%20%3Ccircle%20cx%3D%2240%22%20cy%3D%2240%22%20r%3D%2238%22%20stroke%3D%22black%22%20stroke-width%3D%221%22%20fill%3D%22red%22%20%2F%3E%0D%0A%20%20%3Ccircle%20cx%3D%22120%22%20cy%3D%2240%22%20r%3D%2238%22%20stroke%3D%22black%22%20stroke-width%3D%221%22%20fill%3D%22blue%22%20%2F%3E%0D%0A%3C%2Fsvg%3E);
}
.div2:after {
  background-position: -80px 0;
}

For IE8, change to this:

  background-image: url(data:image/png;base64,data......);

I had the same problem recently and this helped me:

    header('Content-Description: File Transfer'); 
    header('Content-Type: application/octet-stream'); 
    header('Content-Disposition: attachment; filename="FILENAME"'); 
    header('Content-Transfer-Encoding: binary'); 
    header('Expires: 0'); 
    header('Cache-Control: must-revalidate, post-check=0, pre-check=0'); 
    header('Pragma: public'); 
    header('Content-Length: ' . filesize("PATH/TO/FILE")); 
    ob_clean(); 
    flush(); 
    readfile(PATH/TO/FILE);      
    exit();

I found this answer here

Finally I manage to ignore the invalid characters and get only the numbers to convert the text to numeric.

SELECT (NULLIF(regexp_replace(split_part(column1, '.', 1), '\D','','g'), '') 
    || '.' || COALESCE(NULLIF(regexp_replace(split_part(column1, '.', 2), '\D','','g'),''),'00')) AS result,column1
FROM (VALUES
    ('ggg'),('3,0 kg'),('15 kg.'),('2x3,25'),('96+109'),('1.10'),('132123')
) strings;  

My solution was to add

    location ~ \.php$ {
    try_files $uri =404;
    fastcgi_split_path_info ^(.+\.php)(/.+)$;
    fastcgi_pass unix:/run/php/php7.0-fpm.sock;
    fastcgi_index index.php;
    fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    include fastcgi_params;

to my custom configuration file, for example etc/nginx/sites-available/example.com.conf

Adding to /etc/nginx/sites-available/default didn't work for me.

The best way to do this is to use view port styles. It just does the work and no other techniques needed.

Code:

div{_x000D_
  height:100vh;_x000D_
}

<div></div>

You should include a path to your command, since cron runs with an extensively cut-down environment. You won't have all the environment variables you have in your interactive shell session.

It's a good idea to specify an absolute path to your script/binary, or define PATH in the crontab itself. To help debug any issues I would also redirect stdout/err to a log file.

Today,I also meet this question.This is my way to solve. Xcode 9.0,iPhone 6s,Automatically manage signing with my account. When I select "iPhone 6s",I found that there is an logo after the iPhone 6s It's the new function of Xcode 9.0 that can run an app on the iPhone without a string connect computer(iPhone and Mac must connect the same Network). So, I try to change this kind of connect way. Open "Devices and Simulators"-> unselect "Connect via network" And then, I clean, rebuild and run my project.It works! I will be happy if this method can help you.

For me, the simplest way to do this is

1) Download and unzip bootstrap into vendor

2) Add the bootstrap path to your config

config.assets.paths << Rails.root.join("vendor/bootstrap-3.3.6-dist")

3) Require them

in css *= require css/bootstrap

in js //= require js/bootstrap

Done!

This methods makes the fonts load without any other special configuration and doesn't require moving the bootstrap files out of their self-contained directory.

Note, it appears to me that if you change the width the thumb width does not change correctly. I didn't take the time to fix it right, i just fixed it for my case. Here is what i did. Couldn't figure out how to contact the original creator.

public void setThumb(Drawable thumb) {
    if (thumb != null) {
        thumb.setCallback(this);

        // Assuming the thumb drawable is symmetric, set the thumb offset
        // such that the thumb will hang halfway off either edge of the
        // progress bar.
        //This was orginally divided by 2, seems you have to adjust here when you adjust width.
        mThumbOffset = (int)thumb.getIntrinsicHeight();
    }

Let's solve this problem for this array:

var array = ['A', 'B', 'C'];

1. Remove only the first: Use If you are sure that the item exist

array.splice(array.indexOf('B'), 1);

2. Remove only the last: Use If you are sure that the item exist

array.splice(array.lastIndexOf('B'), 1);

3. Remove all occurrences:

array = array.filter(v => v !== 'B'); 

I think you could write it that way too. I am also a student so I understand your struggle. A bit late response but ok .

#include<stdio.h>
#define n 3

struct {
    double p[3];//position
    double v[3];//velocity
    double a[3];//acceleration
    double radius;
    double mass;
}bodies[n];

In addition to Tom Mulcahy's answer, if you want to filter by PID on Windows' console, you can create a little batch file like that:

@ECHO OFF

:: find the process id of our app (2nd token)
FOR /F "tokens=1-2" %%A IN ('adb shell ps ^| findstr com.example.my.package') DO SET PID=%%B

:: run logcat and filter the output by PID
adb logcat | findstr %PID%

There are some perfectly capable answers here. However for non-trivial script it may be desirable to retain the code in a cache, or for debugging purposes, or even to have dynamically self-updating code.

To that end, sometimes it's simpler or more robust to interact with Java via command line. Create a temporary directory, output your script and any assets, create the jar. Finally import your new code.

It's a bit beyond the scope of normal eval() use in most languages, though you could certainly implement eval by returning the result from some function in your jar.

Still, thought I'd mention this method as it does fully encapsulate everything Java can do without 3rd party tools, in case of desperation. This method allows me to turn HTML templates into objects and save them, avoiding the need to parse a template at runtime.

Close and re-open the tab. That should do the trick.

Tip : To make Auto size work , the call to sheet.autoSizeColumn(columnNumber) should be made after populating the data into the excel.

Calling the method before populating the data, will have no effect.

The number you are trying to store is too big for the field. Look at the SCALE and PRECISION. The difference between the two is the number of digits ahead of the decimal place that you can store.

select cast (10 as number(1,2)) from dual
             *
ERROR at line 1:
ORA-01438: value larger than specified precision allowed for this column

select cast (15.33 as number(3,2)) from dual
             *
ERROR at line 1:
ORA-01438: value larger than specified precision allowed for this column

Anything at the lower end gets truncated (silently)

select cast (5.33333333 as number(3,2)) from dual;
CAST(5.33333333ASNUMBER(3,2))
-----------------------------
                         5.33

INSERT INTO preliminary_image (style_id,pre_image_status,file_extension,reviewer_id,
uploader_id,is_deleted,last_updated) 

SELECT '4827499',pre_image_status,file_extension,reviewer_id,
uploader_id,'0',last_updated FROM preliminary_image WHERE style_id=4827488

Analysis

We can use above query if we want to copy data from one table to another table in mysql

1. Here source and destination table are same, we can use different tables also.
2. Few columns we are not copying like style_id and is_deleted so we selected them hard coded from another table
3. Table we used in source also contains auto increment field so we left that column and it get inserted automatically with execution of query.

Execution results

1 queries executed, 1 success, 0 errors, 0 warnings

For me the following worked on Jenkins 2.190.1 and was much simpler than some of the other workarounds:

matcher = manager.getLogMatcher('^.*Text we want comes next: (.*)$');

if (matcher.matches()) {
    def myVar = matcher.group(1);
    def envVar = new EnvVars([MY_ENV_VAR: myVar]);
    def newEnv = Environment.create(envVar);
    manager.build.environments.add(0, newEnv);
    // now the matched text from the LogMatcher is passed to an
    // env var we can access at $MY_ENV_VAR in post build steps
}

This was using the Groovy Script plugin with no additional changes to Jenkins.

If you are grouping by some other value, then instead of what you have,

write it as

Sum(CASE WHEN col1 > col2 THEN SUM(col3*col4) ELSE 0 END) as SumSomeProduct

If, otoh, you want to group By the internal expression, (col3*col4) then

write the group By to match the expression w/o the SUM...

Select Sum(Case When col1 > col2 Then col3*col4 Else 0 End) as SumSomeProduct
From ...

Group By Case When col1 > col2 Then col3*col4 Else 0 End 

Finally, if you want to group By the actual aggregate

Select SumSomeProduct, Count(*), <other aggregate functions>
From (Select <other columns you are grouping By>, 
      Sum(Case When col1 > col2 
          Then col3*col4 Else 0 End) as SumSomeProduct
      From Table
      Group By <Other Columns> ) As Z
Group by SumSomeProduct

I had this problem before, and the reason is very simple: Check your variables, if there were strings, so put it in quotes '$your_string_variable_here' ,, if it were numerical keep it without any quotes. for example, if I had these data: $name ( It will be string ) $phone_number ( It will be numerical ) So, it will be like that:

$query = "INSERT INTO users (name, phone) VALUES ('$name', $phone)"; Just like that and it will be fixed ^_^

I had the same problem and finally figured out, that it was the Logitech SetPoint Software.

Deinstalled it - and the error is gone.

It is not possible to write exception-safe code under the assumption that "any line can throw". The design of exception-safe code relies critically on certain contracts/guarantees that you are supposed to expect, observe, follow and implement in your code. It is absolutely necessary to have code that is guaranteed to never throw. There are other kinds of exception guarantees out there.

In other words, creating exception-safe code is to a large degree a matter of program design not just a matter of plain coding.

Can't add a comment to the solution but that didn't work for me. The solution that worked for me was to use:

var des = (MyClass)Newtonsoft.Json.JsonConvert.DeserializeObject(response, typeof(MyClass)); 
return des.data.Count.ToString();

Deserializing JSON array into strongly typed .NET object

I found another way to solve it - use Table Lock. Sure, it can be unappropriate for your application - if you need to update table at same time.

See: Try using LOCK TABLES to lock the entire table, instead of the default action of InnoDB's MVCC row-level locking. If I'm not mistaken, the "lock table" is referring to the InnoDB internal structure storing row and version identifiers for the MVCC implementation with a bit identifying the row is being modified in a statement, and with a table of 60 million rows, probably exceeds the memory allocated to it. The LOCK TABLES command should alleviate this problem by setting a table-level lock instead of row-level:

SET @@AUTOCOMMIT=0;
LOCK TABLES avgvol WRITE, volume READ;
INSERT INTO avgvol(date,vol)
SELECT date,avg(vol) FROM volume
GROUP BY date;
UNLOCK TABLES;

For Python 3

Remove the rb argument and use either r or don't pass argument (default read mode).

with open( <path-to-file>, 'r' ) as theFile:
    reader = csv.DictReader(theFile)
    for line in reader:
        # line is { 'workers': 'w0', 'constant': 7.334, 'age': -1.406, ... }
        # e.g. print( line[ 'workers' ] ) yields 'w0'
        print(line)

For Python 2

import csv
with open( <path-to-file>, "rb" ) as theFile:
    reader = csv.DictReader( theFile )
    for line in reader:
        # line is { 'workers': 'w0', 'constant': 7.334, 'age': -1.406, ... }
        # e.g. print( line[ 'workers' ] ) yields 'w0'

Python has a powerful built-in CSV handler. In fact, most things are already built in to the standard library.

Well, for a link, there must be a link tag around. what you can also do is that make a css class for the button and assign that class to the link tag. like,

#btn {_x000D_
  background: url(https://image.flaticon.com/icons/png/128/149/149668.png) no-repeat 0 0;_x000D_
  display: block;_x000D_
  width: 128px;_x000D_
  height: 128px;_x000D_
  border: none;_x000D_
  outline: none;_x000D_
}

<a href="btnlink.html" id="btn"></a>

Just type the following commands from console.

cd /your_project
heroku restart

You can do so by creating an array of dtype=object. If you try to assign a long string to a normal numpy array, it truncates the string:

>>> a = numpy.array(['apples', 'foobar', 'cowboy'])
>>> a[2] = 'bananas'
>>> a
array(['apples', 'foobar', 'banana'], 
      dtype='|S6')

But when you use dtype=object, you get an array of python object references. So you can have all the behaviors of python strings:

>>> a = numpy.array(['apples', 'foobar', 'cowboy'], dtype=object)
>>> a
array([apples, foobar, cowboy], dtype=object)
>>> a[2] = 'bananas'
>>> a
array([apples, foobar, bananas], dtype=object)

Indeed, because it's an array of objects, you can assign any kind of python object to the array:

>>> a[2] = {1:2, 3:4}
>>> a
array([apples, foobar, {1: 2, 3: 4}], dtype=object)

However, this undoes a lot of the benefits of using numpy, which is so fast because it works on large contiguous blocks of raw memory. Working with python objects adds a lot of overhead. A simple example:

>>> a = numpy.array(['abba' for _ in range(10000)])
>>> b = numpy.array(['abba' for _ in range(10000)], dtype=object)
>>> %timeit a.copy()
100000 loops, best of 3: 2.51 us per loop
>>> %timeit b.copy()
10000 loops, best of 3: 48.4 us per loop

So, it's easy to detect the Xoom, hard to detect if a specific Android version is mobile or not.

High-Level Design (HLD) involves decomposing a system into modules, and representing the interfaces & invocation relationships among modules. An HLD is referred to as software architecture.

LLD, also known as a detailed design, is used to design internals of the individual modules identified during HLD i.e. data structures and algorithms of the modules are designed and documented.

Now, HLD and LLD are actually used in traditional Approach (Function-Oriented Software Design) whereas, in OOAD, the system is seen as a set of objects interacting with each other.

As per the above definitions, a high-level design document will usually include a high-level architecture diagram depicting the components, interfaces, and networks that need to be further specified or developed. The document may also depict or otherwise refer to work flows and/or data flows between component systems.

Class diagrams with all the methods and relations between classes come under LLD. Program specs are covered under LLD. LLD describes each and every module in an elaborate manner so that the programmer can directly code the program based on it. There will be at least 1 document for each module. The LLD will contain - a detailed functional logic of the module in pseudo code - database tables with all elements including their type and size - all interface details with complete API references(both requests and responses) - all dependency issues - error message listings - complete inputs and outputs for a module.

With atan2 you can determine the quadrant as stated here.

You can use atan2 if you need to determine the quadrant.

Do you have Adobe PDFL or Acrobat Professional? You can use preflight operation if you do.

You can do this with the scp command, which uses the ssh protocol to copy files across machines. It extends the syntax of cp to allow references to other systems:

scp username1@hostname1:/path/to/file username2@hostname2:/path/to/other/file

Copy something from this machine to some other machine:

scp /path/to/local/file username@hostname:/path/to/remote/file

Copy something from another machine to this machine:

scp username@hostname:/path/to/remote/file /path/to/local/file

Copy with a port number specified:

scp -P 1234 username@hostname:/path/to/remote/file /path/to/local/file

If you target android 5.0 and above. You could use:

Activity.startLockTask()

Just with the above answer I hope it was the problem.

$_POST['search'] instead of $_post['search']

And again use LIKE '%$name%' instead of LIKE '%{$name}%'

try following js code

location = '..'

declare @testVal varchar(20)

set @testVal = '?t/es?ti/n*g 1*2?3*'

select @testVal = REPLACE(@testVal, item, '') from (select '?' item union select '*' union select '/') list

select @testVal;

Try this

.Bold { font-weight: bold; }

<span> normal text</span> <br>_x000D_
<span class="Bold"> bold text</span> <br>_x000D_
<span> normal text</span> <spanspan>

In asp.net is more to do, to get completely running under another namespace.

• Copy your source folder and rename it to your new project name.
• Open it and Replace all by Ctrl + H and be sure to include all Replace everything
• Press F2 on your Projectname and rename it to your new project name
• go to your project properties and adjust it, coz everything has gone and you need to make a new Debug Profile Profile to Create
• All dependencies have now an exclamation mark - restart visual studio
• Clean your solution and Run it and it should work :)

Got an answer for this problem without using ExifInterface. We can get the rotation of the camera either front camera or back camera whichever you are using then while creating the Bitmap we can rotate the bitmap using Matrix.postRotate(degree)

public int getRotationDegree() {
    int degree = 0;

    for (int i = 0; i < Camera.getNumberOfCameras(); i++) {
        Camera.CameraInfo info = new Camera.CameraInfo();
        Camera.getCameraInfo(i, info);
        if (info.facing == Camera.CameraInfo.CAMERA_FACING_BACK) {
            degree = info.orientation;

            return degree;
        }
    }

    return degree;
}

After calculating the rotation you can rotate you bitmap like below:

 Matrix matrix = new Matrix();

 matrix.postRotate(getRotationDegree());

 Bitmap.createBitmap(bm, 0, 0, bm.getWidth(), bm.getHeight(), matrix, true);

Herare bm should be your bitmap.

If you want to know the rotation of your front camera just change Camera.CameraInfo.CAMERA_FACING_BACK to Camera.CameraInfo.CAMERA_FACING_FRONT above.

I hope this helps.

Type cast your object to an array.

$arr =  (array) $Obj;

It will solve your problem.

You can filter all characters from the string that are not printable using string.printable, like this:

>>> s = "some\x00string. with\x15 funny characters"
>>> import string
>>> printable = set(string.printable)
>>> filter(lambda x: x in printable, s)
'somestring. with funny characters'

string.printable on my machine contains:

0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
!"#$%&\'()*+,-./:;<=>?@[\\]^_`{|}~ \t\n\r\x0b\x0c

EDIT: On Python 3, filter will return an iterable. The correct way to obtain a string back would be:

''.join(filter(lambda x: x in printable, s))

I will advise you to uninstall the bs4 library by using this command:

pip uninstall bs4

and then install it using this command:

sudo apt-get install python3-bs4

I was facing the same problem in my Linux Ubuntu when I used the following command for installing bs4 library:

pip install bs4

function isPrime(num) { // returns boolean
  if (num <= 1) return false; // negatives
  if (num % 2 == 0 && num > 2) return false; // even numbers
  const s = Math.sqrt(num); // store the square to loop faster
  for(let i = 3; i <= s; i += 2) { // start from 3, stop at the square, increment in twos
      if(num % i === 0) return false; // modulo shows a divisor was found
  }
  return true;
}
console.log(isPrime(121));

Thanks to Zeph for fixing my mistakes.

In Javascript method names are camel case, so it's replace, not Replace:

$scope.newString = oldString.replace("stackover","NO");

Note that contrary to how the .NET Replace method works, the Javascript replace method replaces only the first occurrence if you are using a string as first parameter. If you want to replace all occurrences you need to use a regular expression so that you can specify the global (g) flag:

$scope.newString = oldString.replace(/stackover/g,"NO");

See this example.

Use the zzz format specifier to get the timezone offset as hours and minutes. You also want to use the HH format specifier to get the hours in 24 hour format.

DateTime.Now.ToString("yyyy-MM-ddTHH:mm:sszzz")

Result:

2011-08-09T23:49:58+02:00

Some culture settings uses periods instead of colons for time, so you might want to use literal colons instead of time separators:

DateTime.Now.ToString("yyyy-MM-ddTHH':'mm':'sszzz")

Custom Date and Time Format Strings

You can check that theHref is defined by checking against undefined.

if (undefined !== theHref && theHref.length) {
    // `theHref` is not undefined and has truthy property _length_
    // do stuff
} else {
    // do other stuff
}

If you want to also protect yourself against falsey values like null then check theHref is truthy, which is a little shorter

if (theHref && theHref.length) {
    // `theHref` is truthy and has truthy property _length_
}

NSDate has a compare function.

compare: Returns an NSComparisonResult value that indicates the temporal ordering of the receiver and another given date.

(NSComparisonResult)compare:(NSDate *)anotherDate

Parameters: anotherDate The date with which to compare the receiver. This value must not be nil. If the value is nil, the behavior is undefined and may change in future versions of Mac OS X.

Return Value:

• If the receiver and anotherDate are exactly equal to each other, NSOrderedSame
• If the receiver is later in time than anotherDate, NSOrderedDescending
• If the receiver is earlier in time than anotherDate, NSOrderedAscending.

//defines an array of 280 pointers (1120 or 2240 bytes)
int  *pointer1 [280];

//defines a pointer (4 or 8 bytes depending on 32/64 bits platform)
int (*pointer2)[280];      //pointer to an array of 280 integers
int (*pointer3)[100][280]; //pointer to an 2D array of 100*280 integers

Using pointer2 or pointer3 produce the same binary except manipulations as ++pointer2 as pointed out by WhozCraig.

I recommend using typedef (producing same binary code as above pointer3)

typedef int myType[100][280];
myType *pointer3;

Note: Since C++11, you can also use keyword using instead of typedef

using myType = int[100][280];
myType *pointer3;

in your example:

myType *pointer;                // pointer creation
pointer = &tab1;                // assignation
(*pointer)[5][12] = 517;        // set (write)
int myint = (*pointer)[5][12];  // get (read)

Note: If the array tab1 is used within a function body => this array will be placed within the call stack memory. But the stack size is limited. Using arrays bigger than the free memory stack produces a stack overflow crash.

The full snippet is online-compilable at gcc.godbolt.org

int main()
{
    //defines an array of 280 pointers (1120 or 2240 bytes)
    int  *pointer1 [280];
    static_assert( sizeof(pointer1) == 2240, "" );

    //defines a pointer (4 or 8 bytes depending on 32/64 bits platform)
    int (*pointer2)[280];      //pointer to an array of 280 integers
    int (*pointer3)[100][280]; //pointer to an 2D array of 100*280 integers  
    static_assert( sizeof(pointer2) == 8, "" );
    static_assert( sizeof(pointer3) == 8, "" );

    // Use 'typedef' (or 'using' if you use a modern C++ compiler)
    typedef int myType[100][280];
    //using myType = int[100][280];

    int tab1[100][280];

    myType *pointer;                // pointer creation
    pointer = &tab1;                // assignation
    (*pointer)[5][12] = 517;        // set (write)
    int myint = (*pointer)[5][12];  // get (read)

    return myint;
}

There is big difference between dot (".") and text() :-

• The dot (".") in XPath is called the "context item expression" because it refers to the context item. This could be match with a node (such as an element, attribute, or text node) or an atomic value (such as a string, number, or boolean). While text() refers to match only element text which is in string form.

• The dot (".") notation is the current node in the DOM. This is going to be an object of type Node while Using the XPath function text() to get the text for an element only gets the text up to the first inner element. If the text you are looking for is after the inner element you must use the current node to search for the string and not the XPath text() function.

For an example :-

<a href="something.html">
  <img src="filename.gif">
  link
</a>

Here if you want to find anchor a element by using text link, you need to use dot ("."). Because if you use //a[contains(.,'link')] it finds the anchor a element but if you use //a[contains(text(),'link')] the text() function does not seem to find it.

Hope it will help you..:)

I Found Solution Of You Question But In Stack Not Allow to Upload Video See the link below it show better explain

How to link two (multiple) workbooks and cells in Excel...

The first push should be a:

git push -u origin branchname

That would make sure:

• your local branch has a remote tracking branch of the same name referring an upstream branch in your remote repo 'origin',
• this is compliant with the default push policy 'simple'

Any future git push will, with that default policy, only push the current branch, and only if that branch has an upstream branch with the same name.
that avoid pushing all matching branches (previous default policy), where tons of test branches were pushed even though they aren't ready to be visible on the upstream repo.

Depending on what I'm using it for, or if I'm doing something that others will use, I typically just input("Do eighteen backflips to continue") if it's just for me, if others will be using I just create a batch file and pause it after

cd '/file/path/here'
python yourfile.py
pause 

I use the above if there is going to be files renamed, moved, copied, etc. and my cmd needs to be in the particular folder for things to fall where I want them, otherwise - just

python '/path/to/file/yourfile.py'
pause

I was also confused about them. See this example below:

<Window x:Class="WpfApplicationWPF.CommandsWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="CommandsWindow" Height="300" Width="300">

    <StackPanel>
        <Button Name="ButtonNew" 
                Click="ButtonNew_Click" 
                Background="{DynamicResource PinkBrush}">NEW</Button>
        <Image Name="ImageNew" 
               Source="pack://application:,,,/images/winter.jpg"></Image>
    </StackPanel>


    <Window.Background>
        <DynamicResource ResourceKey="PinkBrush"></DynamicResource>
    </Window.Background>

</Window>

Here I have used dynamic resource for button and window and have not declared it anywhere.Upon runtime, the ResourceDictionary of the hierarchy will be checked.Since I have not defined it, I guess the default will be used.

If I add the code below to click event of Button, since they use DynamicResource, the background will be updated accordingly.

private void ButtonNew_Click(object sender, RoutedEventArgs e)
{
    this.Resources.Add(  "PinkBrush"
                         ,new SolidColorBrush(SystemColors.DesktopColor)
                       );
}

If they had used StaticResource:

• The resource has to be declared in XAML
• And that too "before" they are used.

Hope I cleared some confusion.

Complete working example in Kotlin, I have replaced my API keys with 1111...

        val apiService = API.getInstance().retrofit.create(MyApiEndpointInterface::class.java)
        val params = HashMap<String, String>()
        params["q"] =  "munich,de"
        params["APPID"] = "11111111111111111"

        val call = apiService.getWeather(params)

        call.enqueue(object : Callback<WeatherResponse> {
            override fun onFailure(call: Call<WeatherResponse>?, t: Throwable?) {
                Log.e("Error:::","Error "+t!!.message)
            }

            override fun onResponse(call: Call<WeatherResponse>?, response: Response<WeatherResponse>?) {
                if (response != null && response.isSuccessful && response.body() != null) {
                    Log.e("SUCCESS:::","Response "+ response.body()!!.main.temp)

                    temperature.setText(""+ response.body()!!.main.temp)

                }
            }

        })

I always prefer to check time in hours, minutes and seconds (%H:%M:%S) format:

from datetime import datetime
start = datetime.now()
# your code
end = datetime.now()
time_taken = end - start
print('Time: ',time_taken) 

output:

Time:  0:00:00.000019

This is a start, I don't think it works exactly as you intend, but it at least produces a consistent result.

    }

    public static String pathJoin(final String ... pathElements)
    {
        final String path;

        if(pathElements == null || pathElements.length == 0)
        {
            path = File.separator;
        }
        else
        {
            final StringBuilder builder;

            builder = new StringBuilder();

            for(final String pathElement : pathElements)
            {
                final String sanitizedPathElement;

                // the "\\" is for Windows... you will need to come up with the 
                // appropriate regex for this to be portable
                sanitizedPathElement = pathElement.replaceAll("\\" + File.separator, "");

                if(sanitizedPathElement.length() > 0)
                {
                    builder.append(sanitizedPathElement);
                    builder.append(File.separator);
                }
            }

            path = builder.toString();
        }

        return (path);
    }
}

When you open a transaction nothing gets locked by itself. But if you execute some queries inside that transaction, depending on the isolation level, some rows, tables or pages get locked so it will affect other queries that try to access them from other transactions.

• To remove white spaces:

1) To remove white space everywhere:

df.columns = df.columns.str.replace(' ', '')

2) To remove white space at the beginning of string:

df.columns = df.columns.str.lstrip()

3) To remove white space at the end of string:

df.columns = df.columns.str.rstrip()

4) To remove white space at both ends:

df.columns = df.columns.str.strip()

• To replace white spaces with other characters (underscore for instance):

5) To replace white space everywhere

df.columns = df.columns.str.replace(' ', '_')

6) To replace white space at the beginning:

df.columns = df.columns.str.replace('^ +', '_')

7) To replace white space at the end:

df.columns = df.columns.str.replace(' +$', '_')

8) To replace white space at both ends:

df.columns = df.columns.str.replace('^ +| +$', '_')

All above applies to a specific column as well, assume you have a column named col, then just do:

df[col] = df[col].str.strip()  # or .replace as above

If you do not need the recording and playback functionality in your app, using off-the-shelf streaming app and player is a reasonable choice.

If you do need them to be in your app, however, you will have to look into MediaRecorder API (for the server/camera app) and MediaPlayer (for client/player app).

Quick sample code for the server:

// this is your network socket
ParcelFileDescriptor pfd = ParcelFileDescriptor.fromSocket(socket);
mCamera = getCameraInstance();
mMediaRecorder = new MediaRecorder();
mCamera.unlock();
mMediaRecorder.setCamera(mCamera);
mMediaRecorder.setAudioSource(MediaRecorder.AudioSource.CAMCORDER);
mMediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);
// this is the unofficially supported MPEG2TS format, suitable for streaming (Android 3.0+)
mMediaRecorder.setOutputFormat(8);
mMediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.DEFAULT);
mMediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.DEFAULT);
mediaRecorder.setOutputFile(pfd.getFileDescriptor());
mMediaRecorder.setPreviewDisplay(mPreview.getHolder().getSurface());
mMediaRecorder.prepare();
mMediaRecorder.start();

On the player side it is a bit tricky, you could try this:

// this is your network socket, connected to the server
ParcelFileDescriptor pfd = ParcelFileDescriptor.fromSocket(socket);
mMediaPlayer = new MediaPlayer();
mMediaPlayer.setDataSource(pfd.getFileDescriptor());
mMediaPlayer.prepare();
mMediaPlayer.start();

Unfortunately mediaplayer tends to not like this, so you have a couple of options: either (a) save data from socket to file and (after you have a bit of data) play with mediaplayer from file, or (b) make a tiny http proxy that runs locally and can accept mediaplayer's GET request, reply with HTTP headers, and then copy data from the remote server to it. For (a) you would create the mediaplayer with a file path or file url, for (b) give it a http url pointing to your proxy.

Additionally you can use an app like AutoStart if you dont want to modify the code, to launch an android application at startup: AutoStart - No root

You can also try ternary operator. Something like this

Let me just add a warning to all the existing answers:

When using the SELECT ... FROM syntax, you should keep in mind that it is proprietary syntax for T-SQL and is non-deterministic. The worst part is, that you get no warning or error, it just executes smoothly.

Full explanation with example is in the documentation:

Use caution when specifying the FROM clause to provide the criteria for the update operation. The results of an UPDATE statement are undefined if the statement includes a FROM clause that is not specified in such a way that only one value is available for each column occurrence that is updated, that is if the UPDATE statement is not deterministic.

Based on process id, we can send the signal to process to terminate forcefully or gracefully or any other signal.

List all process :

C:\>tasklist

To kill the process:

C:\>Taskkill /IM firefox.exe /F
or
C:\>Taskkill /PID 26356 /F

To add a header just add the following code to the location block where you want to add the header:

location some-location {
  add_header X-my-header my-header-content;      
}

Obviously, replace the x-my-header and my-header-content with what you want to add. And that's all there is to it.

It's been awhile since I've done anything with batch files but I think that the following works:

find /c "string" file
if %errorlevel% equ 1 goto notfound
echo found
goto done
:notfound
echo notfound
goto done
:done

This is really a proof of concept; clean up as it suits your needs. The key is that find returns an errorlevel of 1 if string is not in file. We branch to notfound in this case otherwise we handle the found case.

In Visual Studio 2008 and Visual Studio 2005 at least, you can specify changes to environment variables in the project settings.

Open your project. Go to Project -> Properties... Under Configuration Properties -> Debugging, edit the 'Environment' value to set environment variables.

For example, if you want to add the directory "c:\foo\bin" to the path when debugging your application, set the 'Environment' value to "PATH=%PATH%;c:\foo\bin".

Morgan should not be used to log in the way you're describing. Morgan was built to do logging in the way that servers like Apache and Nginx log to the error_log or access_log. For reference, this is how you use morgan:

var express     = require('express'),
    app         = express(),
    morgan      = require('morgan'); // Require morgan before use

// You can set morgan to log differently depending on your environment
if (app.get('env') == 'production') {
  app.use(morgan('common', { skip: function(req, res) { return res.statusCode < 400 }, stream: __dirname + '/../morgan.log' }));
} else {
  app.use(morgan('dev'));
}

Note the production line where you see morgan called with an options hash {skip: ..., stream: __dirname + '/../morgan.log'}

The stream property of that object determines where the logger outputs. By default it's STDOUT (your console, just like you want) but it'll only log request data. It isn't going to do what console.log() does.

If you want to inspect things on the fly use the built in util library:

var util = require('util');
console.log(util.inspect(anyObject)); // Will give you more details than console.log

So the answer to your question is that you're asking the wrong question. But if you still want to use Morgan for logging requests, there you go.

You can use Request object or Uri object to get host of url.

Using Request.Url

string host = Request.Url.Host;

Using Uri

Uri myUri = new Uri("http://www.contoso.com:8080/");   
string host = myUri.Host;  // host is "www.contoso.com"

why not

def pairwise(iterable):
    "s -> (s0,s1), (s1,s2), (s2, s3), ..."
    a, b = tee(iterable)
    next(b, None)
    return zip(a, b)

It is documented in Python doc . You can easily extend it to wider window.

Here is my simplistic approach. I am using the classic builder pattern for this. It is typesafe (no boxing/unboxing) and also compatbile with .NET 2.0 (no extension methods etc.).

It is used like this:

public override int GetHashCode()
{
    HashBuilder b = new HashBuilder();
    b.AddItems(this.member1, this.member2, this.member3);
    return b.Result;
} 

And here is the acutal builder class:

internal class HashBuilder
{
    private const int Prime1 = 17;
    private const int Prime2 = 23;
    private int result = Prime1;

    public HashBuilder()
    {
    }

    public HashBuilder(int startHash)
    {
        this.result = startHash;
    }

    public int Result
    {
        get
        {
            return this.result;
        }
    }

    public void AddItem<T>(T item)
    {
        unchecked
        {
            this.result = this.result * Prime2 + item.GetHashCode();
        }
    }

    public void AddItems<T1, T2>(T1 item1, T2 item2)
    {
        this.AddItem(item1);
        this.AddItem(item2);
    }

    public void AddItems<T1, T2, T3>(T1 item1, T2 item2, T3 item3)
    {
        this.AddItem(item1);
        this.AddItem(item2);
        this.AddItem(item3);
    }

    public void AddItems<T1, T2, T3, T4>(T1 item1, T2 item2, T3 item3, 
        T4 item4)
    {
        this.AddItem(item1);
        this.AddItem(item2);
        this.AddItem(item3);
        this.AddItem(item4);
    }

    public void AddItems<T1, T2, T3, T4, T5>(T1 item1, T2 item2, T3 item3, 
        T4 item4, T5 item5)
    {
        this.AddItem(item1);
        this.AddItem(item2);
        this.AddItem(item3);
        this.AddItem(item4);
        this.AddItem(item5);
    }        

    public void AddItems<T>(params T[] items)
    {
        foreach (T item in items)
        {
            this.AddItem(item);
        }
    }
}

Try:

SELECT post_datetime 
FROM post 
WHERE type = 'published' 
ORDER BY post_datetime DESC 
LIMIT 3

You can simply do tar -xvf <rpm file> as well!

SELECT *
FROM BOOKING_SESSION
WHERE TO_CHAR(T_SESSION_DATETIME, 'DD-MM-YYYY') ='20-03-2012';

This code will convert the text 0xA7.0x9B.0x46.0x8D.0x1E.0x52.0xA7.0x9B.0x7B.0x31.0xD2 into a stream of 11 bytes with equivalent values. These bytes will be written to standard out.

TESTDATA=$(echo '0xA7.0x9B.0x46.0x8D.0x1E.0x52.0xA7.0x9B.0x7B.0x31.0xD2' | tr '.' ' ')
for c in $TESTDATA; do
    echo $c | xxd -r
done

As others have pointed out, this will not result in a printable ASCII string for the simple reason that the specified bytes are not ASCII. You need post more information about how you obtained this string for us to help you with that.

How it works: xxd -r translates hexadecimal data to binary (like a reverse hexdump). xxd requires that each line start off with the index number of the first character on the line (run hexdump on something and see how each line starts off with an index number). In our case we want that number to always be zero, since each execution only has one line. As luck would have it, our data already has zeros before every character as part of the 0x notation. The lower case x is ignored by xxd, so all we have to do is pipe each 0xhh character to xxd and let it do the work.

The tr translates periods to spaces so that for will split it up correctly.

Execute the workbench.action.reloadWindow command.

There are some ways to do so:

1. Open the command palette (Ctrl + Shift + P) and execute the command:

   >Reload Window    
   

2. Define a keybinding for the command (for example CTRL+F5) in keybindings.json:

   [
     {
       "key": "ctrl+f5",
       "command": "workbench.action.reloadWindow",
       "when": "editorTextFocus"
     }
   ]
   

Ctrl-/ will insert // style commenting, for javascript, etc
Ctrl-/ will insert <!-- --> comments for HTML,
Ctrl-/ will insert # comments for Ruby,
..etc

But does not work perfectly on HTML <script> tags.

HTML <script> ..blah.. </script> tags:
Ctrl-/ twice (ie Ctrl-/Ctrl-/) will effectively comment out the line:

• The first Ctrl-/ adds // to the beginning of the line,
  which comments out the script tag, but adds "//" text to your webpage.
• The second Ctrl-/ then surrounds that in <!-- --> style comments, which accomplishes the task.

Ctrl--Shift-/ does not produce multi-line comments on HTML (or even single line comments), but does
add /* */ style multi-line comments in Javascript, text, and other file formats.

--

[I added as a new answer since I could not add comments.
I included this info because this is the info I was looking for, and this is the only related StackOverflow page from my search results.
I since discovered the / / trick for HTML script tags and decided to share this additional information, since it requires a slight variation of the usual catch-all (and reported above)
/ and Ctrl--Shift-/ method of commenting out one's code in sublime.]

The characters '<', and '>', are to indicate a place-holder, you should remove them to read:

php /usr/local/solusvm/scripts/pass.php --type=admin --comm=change --username=ADMINUSERNAME

In my case, it's a typo caused this issue:

<VirtualHost *.8080>

should be

<VirtualHost *:8080>

• To run https functionality or SSL authentication in flask application you first install "pyOpenSSL" python package using:

   pip install pyopenssl
  

• Next step is to create 'cert.pem' and 'key.pem' using following command on terminal :

   openssl req -x509 -newkey rsa:4096 -nodes -out cert.pem -keyout key.pem -days 365
  

• Copy generated 'cert.pem' and 'kem.pem' in you flask application project

• Add ssl_context=('cert.pem', 'key.pem') in app.run()

For example:

    from flask import Flask, jsonify

    app = Flask(__name__)

    @app.route('/')

    def index():

        return 'Flask is running!'


    @app.route('/data')

    def names():

        data = {"names": ["John", "Jacob", "Julie", "Jennifer"]}

        return jsonify(data)

  if __name__ == '__main__':

        app.run(ssl_context=('cert.pem', 'key.pem'))

You can use the exit keyword. Here is an example from one of my batch files:

start myProgram.exe param1
exit

While AngularJS allows you to get a hand on a click event (and thus a target of it) with the following syntax (note the $event argument to the setMaster function; documentation here: http://docs.angularjs.org/api/ng.directive:ngClick):

function AdminController($scope) {    
  $scope.setMaster = function(obj, $event){
    console.log($event.target);
  }
}

this is not very angular-way of solving this problem. With AngularJS the focus is on the model manipulation. One would mutate a model and let AngularJS figure out rendering.

The AngularJS-way of solving this problem (without using jQuery and without the need to pass the $event argument) would be:

<div ng-controller="AdminController">
    <ul class="list-holder">
        <li ng-repeat="section in sections" ng-class="{active : isSelected(section)}">
            <a ng-click="setMaster(section)">{{section.name}}</a>
        </li>
    </ul>
    <hr>
    {{selected | json}}
</div>

where methods in the controller would look like this:

$scope.setMaster = function(section) {
    $scope.selected = section;
}

$scope.isSelected = function(section) {
    return $scope.selected === section;
}

git rev-parse --show-toplevel

could be enough if executed within a git repo.
From git rev-parse man page:

--show-toplevel

Show the absolute path of the top-level directory.

For older versions (before 1.7.x), the other options are listed in "Is there a way to get the git root directory in one command?":

git rev-parse --git-dir

That would give the path of the .git directory.

The OP mentions:

git rev-parse --show-prefix

which returns the local path under the git repo root. (empty if you are at the git repo root)

Note: for simply checking if one is in a git repo, I find the following command quite expressive:

git rev-parse --is-inside-work-tree

And yes, if you need to check if you are in a .git git-dir folder:

git rev-parse --is-inside-git-dir

You can also include the guid in the create statement of the table as default, for example:

create table t_sysguid
( id     raw(16) default sys_guid() primary key
, filler varchar2(1000)
)
/

See here: http://rwijk.blogspot.com/2009/12/sysguid.html

Some times less is more, do you really need to know the percentage through the file you are when coding? What about the type of file?

set statusline=%F%m%r%h%w\ 
set statusline+=%{fugitive#statusline()}\    
set statusline+=[%{strlen(&fenc)?&fenc:&enc}]
set statusline+=\ [line\ %l\/%L]          
set statusline+=%{rvm#statusline()}       

I also prefer minimal color as not to distract from the code.

Taken from: https://github.com/krisleech/vimfiles

Note: rvm#statusline is Ruby specific and fugitive#statusline is git specific.

I had to take John Douthat's steps one step further and cd into the submodule's directory, and then remove the Git repository:

cd submodule
rm -fr .git

Then I could commit the files as a part of the parent Git repository without the old reference to a submodule.

The postgresql port is defined in your postgresql.conf file.

For me in Ubuntu 14.04 it is: /etc/postgresql/9.3/main/postgresql.conf

Inside there is a line:

port = 5432

Changing the number there requires restart of postgresql for it to take effect.

In Python, the Scipy library can be used to convert the 2-D NumPy matrix into a Sparse matrix. SciPy 2-D sparse matrix package for numeric data is scipy.sparse

The scipy.sparse package provides different Classes to create the following types of Sparse matrices from the 2-dimensional matrix:

1. Block Sparse Row matrix
2. A sparse matrix in COOrdinate format.
3. Compressed Sparse Column matrix
4. Compressed Sparse Row matrix
5. Sparse matrix with DIAgonal storage
6. Dictionary Of Keys based sparse matrix.
7. Row-based list of lists sparse matrix
8. This class provides a base class for all sparse matrices.

CSR (Compressed Sparse Row) or CSC (Compressed Sparse Column) formats support efficient access and matrix operations.

Example code to Convert Numpy matrix into Compressed Sparse Column(CSC) matrix & Compressed Sparse Row (CSR) matrix using Scipy classes:

import sys                 # Return the size of an object in bytes
import numpy as np         # To create 2 dimentional matrix
from scipy.sparse import csr_matrix, csc_matrix 
# csr_matrix: used to create compressed sparse row matrix from Matrix
# csc_matrix: used to create compressed sparse column matrix from Matrix

create a 2-D Numpy matrix

A = np.array([[1, 0, 0, 0, 0, 0],\
              [0, 0, 2, 0, 0, 1],\
              [0, 0, 0, 2, 0, 0]])
print("Dense matrix representation: \n", A)
print("Memory utilised (bytes): ", sys.getsizeof(A))
print("Type of the object", type(A))

Print the matrix & other details:

Dense matrix representation: 
 [[1 0 0 0 0 0]
 [0 0 2 0 0 1]
 [0 0 0 2 0 0]]
Memory utilised (bytes):  184
Type of the object <class 'numpy.ndarray'>

Converting Matrix A to the Compressed sparse row matrix representation using csr_matrix Class:

S = csr_matrix(A)
print("Sparse 'row' matrix: \n",S)
print("Memory utilised (bytes): ", sys.getsizeof(S))
print("Type of the object", type(S))

The output of print statements:

Sparse 'row' matrix:
(0, 0) 1
(1, 2) 2
(1, 5) 1
(2, 3) 2
Memory utilised (bytes): 56
Type of the object: <class 'scipy.sparse.csr.csc_matrix'>

Converting Matrix A to Compressed Sparse Column matrix representation using csc_matrix Class:

S = csc_matrix(A)
print("Sparse 'column' matrix: \n",S)
print("Memory utilised (bytes): ", sys.getsizeof(S))
print("Type of the object", type(S))

The output of print statements:

Sparse 'column' matrix:
(0, 0) 1
(1, 2) 2
(2, 3) 2
(1, 5) 1
Memory utilised (bytes): 56
Type of the object: <class 'scipy.sparse.csc.csc_matrix'>

As it can be seen the size of the compressed matrices is 56 bytes and the original matrix size is 184 bytes.

Mac OS

To install new Theme on Mac go to Preferences -> Plugins -> Browse Repositories -> Select Category "UI" and search theme name, I recommend "Material Theme UI" click on the green button "Install" and then restart after installation.

If your theme is .icls format.

1. Right click on finder and select "go to folder"
2. type "~/Library/" to go to hidden library folder
3. find "Preferences"
4. find "AndroidStudio2.x"
5. if you don't have "colors" folder then create one
6. paste .icls theme files into colors.

new theme will be installed.

to change themes go to Preferences -> Editor -> Colors & Fonts and then select the scheme.

Below is another method to import spreadsheet data into a MySQL database that doesn't rely on any extra software. Let's assume you want to import your Excel table into the sales table of a MySQL database named mydatabase.

1. Select the relevant cells:

   

2. Paste into Mr. Data Converter and select the output as MySQL:

   

3. Change the table name and column definitions to fit your requirements in the generated output:

CREATE TABLE sales (
  id INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
  Country VARCHAR(255),
  Amount INT,
  Qty FLOAT
);
INSERT INTO sales
  (Country,Amount,Qty)
VALUES
  ('America',93,0.60),
  ('Greece',9377,0.80),
  ('Australia',9375,0.80);

4. If you're using MySQL Workbench or already logged into mysql from the command line, then you can execute the generated SQL statements from step 3 directly. Otherwise, paste the code into a text file (e.g., import.sql) and execute this command from a Unix shell:

   mysql mydatabase < import.sql

   Other ways to import from a SQL file can be found in this Stack Overflow answer.

You don't want to make the function wait, because JavaScript is intended to be non-blocking. Rather return the promise at the end of the function, then the calling function can use the promise to get the server response.

var promise = query.find(); 
return promise; 

//Or return query.find(); 

The following will do.

string datestring = DateTime.Now.ToString("yyyy-MM-dd", CultureInfo.InvariantCulture);

You can do this in the router like that:

ReactDOM.render((
<Router onUpdate={() => window.scrollTo(0, 0)} history={browserHistory}>
     <Route path='/' component={App}>
        <IndexRoute component={Home}></IndexRoute>
        <Route path="/about" component={About}/>
        <Route path="/work">
            <IndexRoute component={Work}></IndexRoute>
            <Route path=":id" component={ProjectFull}></Route>
        </Route>
        <Route path="/blog" component={Blog}/>
    </Route>
 </Router>
), document.getElementById('root'));

The onUpdate={() => window.scrollTo(0, 0)} put the scroll top. For more information check: codepen link

$HOME/.gitconfig is your global config for git.
There are three levels of config files.

 cat $(git rev-parse --show-toplevel)/.git/config

(mentioned by bereal) is your local config, local to the repo you have cloned.

you can also type from within your repo:

git remote -v

And see if there is any remote named 'origin' listed in it.

If not, if that remote (which is created by default when cloning a repo) is missing, you can add it again:

git remote add origin url/to/your/fork

The OP mentions:

Doing git remote -v gives:

upstream git://git.moodle.org/moodle.git (fetch) 
upstream git://git.moodle.org/moodle.git (push)

So 'origin' is missing: the reference to your fork.
See "What is the difference between origin and upstream in github"

I would be careful with setting the display of the element to block. Different elements have the standard display as different things. For example setting display to block for a table row in firefox causes the width of the cells to be incorrect.

Is the name of the element actually test1. I know that .NET can add extra things onto the start or end. The best way to find out if your selector is working properly is by doing this.

alert($('#text1').length);

You might just need to remove the visibility attribute

$('#text1').removeAttr('visibility');

I've created a library with a custom view to solve this issue, and it should be very simple to use. See https://github.com/Comcast/DahDit for more. You can add dashed lines like this:

<com.xfinity.dahdit.DashedLine
    android:layout_width="250dp"
    android:layout_height="wrap_content"
    app:dashHeight="4dp"
    app:dashLength="8dp"
    app:minimumDashGap="3dp"
    app:layout_constraintRight_toRightOf="parent"
    android:id="@+id/horizontal_dashes"/>

my problem was to copy the whole source files contains .idea directory and my webstorm terminal commands were run on the original directory of the source
I delete the .idea directory and it worked fine

Check out this MD5 implementation for JavaScript. Its BSD Licensed and really easy to use. Example:

md5 = hex_md5("message to digest")

On Windows (WAMP) in CLI ini file:

X:\wamp\bin\php\php5.x.xx\php.ini

comment line

; XDEBUG Extension

;zend_extension = "X:/wamp/bin/php/php5.x.xx/zend_ext/php_xdebug-xxxxxx.dll"

Apache will process xdebug, and composer will not.

First you are linking the file that is here:

<script src="../Script/login.js"> 

Which would lead the website to a file in the Folder Script, but then in the second paragraph you are saying that the folder name is

and also i have onother folder named scripts that contains the the following login.js file

So, this won't work! Because you are not accessing the correct file. To do that please write the code as

<script src="/script/login.js"></script>

Try removing the .. from the beginning of the code too.

This way, you'll reach the js file where the function would run!

Just to make sure:

Just to make sure that the files are attached the HTML DOM, then please open Developer Tools (F12) and in the network workspace note each request that the browser makes to the server. This way you will learn which files were loaded and which weren't, and also why they were not!

Good luck.

To answer your direct question, it is:

Range("A1").NumberFormat = "@"

Or

Cells(1,1).NumberFormat = "@"

However, I suggest making changing the format to what you actually want displayed. This allows you to retain the data type in the cell and easily use cell formulas to manipulate the data.

I do it with this python one-liner:

python -c "import subprocess as sp;[sp.call('cordova plugin rm ' + p.split()[0], shell=True) for p in sp.check_output('cordova plugin', shell=True).split('\n') if p]"

Obviously it doesn't handle any sort of error conditions, but it gets the job done.

tl;dr

Instant.parse ( "2010-04-05T17:16:00Z" )

ISO 8601 Standard

Your String complies with the ISO 8601 standard (of which the mentioned RFC 3339 is a profile).

Avoid java.util.Date

The java.util.Date and .Calendar classes bundled with Java are notoriously troublesome. Avoid them.

Instead use either the Joda-Time library or the new java.time package in Java 8. Both use ISO 8601 as their defaults for parsing and generating string representations of date-time values.

java.time

The java.time framework built into Java 8 and later supplants the troublesome old java.util.Date/.Calendar classes. The new classes are inspired by the highly successful Joda-Time framework, intended as its successor, similar in concept but re-architected. Defined by JSR 310. Extended by the ThreeTen-Extra project. See the Tutorial.

The Instant class in java.time represents a moment on the timeline in UTC time zone.

The Z at the end of your input string means Zulu which stands for UTC. Such a string can be directly parsed by the Instant class, with no need to specify a formatter.

String input = "2010-04-05T17:16:00Z";
Instant instant = Instant.parse ( input );

Dump to console.

System.out.println ( "instant: " + instant );

instant: 2010-04-05T17:16:00Z

From there you can apply a time zone (ZoneId) to adjust this Instant into a ZonedDateTime. Search Stack Overflow for discussion and examples.

If you must use a java.util.Date object, you can convert by calling the new conversion methods added to the old classes such as the static method java.util.Date.from( Instant ).

java.util.Date date = java.util.Date.from( instant );

Joda-Time

Example in Joda-Time 2.5.

DateTimeZone timeZone = DateTimeZone.forID( "Europe/Paris" ):
DateTime dateTime = new DateTime( "2010-04-05T17:16:00Z", timeZone );

Convert to UTC.

DateTime dateTimeUtc = dateTime.withZone( DateTimeZone.UTC );

Convert to a java.util.Date if necessary.

java.util.Date date = dateTime.toDate();

I built one of the first SOAP servers, including code generation and WSDL generation, from the original spec as it was being developed, when I was working at Hewlett-Packard. I do NOT recommend using SOAP for anything.

The acronym "SOAP" is a lie. It is not Simple, it is not Object-oriented, it defines no Access rules. It is, arguably, a Protocol. It is Don Box's worst spec ever, and that's quite a feat, as he's the man who perpetrated "COM".

There is nothing useful in SOAP that can't be done with REST for transport, and JSON, XML, or even plain text for data representation. For transport security, you can use https. For authentication, basic auth. For sessions, there's cookies. The REST version will be simpler, clearer, run faster, and use less bandwidth.

XML-RPC clearly defines the request, response, and error protocols, and there are good libraries for most languages. However, XML is heavier than you need for many tasks.

In case of circle all you need is one div, but in case of hollow square you need to have 2 divs. The divs are having a display of inline-block which you can change accordingly. Live Codepen link: Click Me

In case of circle all you need to change is the border properties and the dimensions(width and height) of circle. If you want to change color just change the border color of hollow-circle.

In case of the square background-color property needs to be changed depending upon the background of page or the element upon which you want to place the hollow-square. Always keep the inner-circle dimension small as compared to the hollow-square. If you want to change color just change the background-color of hollow-square. The inner-circle is centered upon the hollow-square using the position, top, left, transform properties just don't mess with them.

Code is as follows:

/* CSS Code */_x000D_
_x000D_
.hollow-circle {_x000D_
  width: 4rem;_x000D_

Parameter int defStyleAttr does not specifies the style. From the Android documentation:

defStyleAttr - An attribute in the current theme that contains a reference to a style resource that supplies default values for the view. Can be 0 to not look for defaults.

To setup the style in View constructor we have 2 possible solutions:

1. With use of ContextThemeWrapper:

   ContextThemeWrapper wrappedContext = new ContextThemeWrapper(yourContext, R.style.your_style);
   TextView textView = new TextView(wrappedContext, null, 0);
   

2. With four-argument constructor (available starting from LOLLIPOP):

   TextView textView = new TextView(yourContext, null, 0, R.style.your_style);
   

Key thing for both solutions - defStyleAttr parameter should be 0 to apply our style to the view.

I use this:

import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.IOException;
import java.io.InputStream;

public class IconImageUtilities
{
    public static void setIconImage(Window window)
    {
        try
        {
            InputStream imageInputStream = window.getClass().getResourceAsStream("/Icon.png");
            BufferedImage bufferedImage = ImageIO.read(imageInputStream);
            window.setIconImage(bufferedImage);
        } catch (IOException exception)
        {
            exception.printStackTrace();
        }
    }
}

Just place your image called Icon.png in the resources folder and call the above method with itself as parameter inside a class extending a class from the Window family such as JFrame or JDialog:

IconImageUtilities.setIconImage(this);

If you want to be correct, use INFORMATION_SCHEMA.

SELECT * 
FROM information_schema.tables
WHERE table_schema = 'yourdb' 
    AND table_name = 'testtable'
LIMIT 1;

Alternatively, you can use SHOW TABLES

SHOW TABLES LIKE 'yourtable';

If there is a row in the resultset, table exists.

Try use While/Wend and Do While / Loop statements...

i = 1
While i < N + 1
Do While true
    [Code]
    If Condition1 Then
       Exit Do
    End If

    [MoreCode]
    If Condition2 Then
       Exit Do
    End If

    [...]

    Exit Do
Loop
Wend

You do not have to install something.

parseInt(req.params.year, 10);

should work properly.

console.log(typeof parseInt(req.params.year)); // returns 'number'

What is your output, if you use parseInt? is it still a string?

If you can comment out code and your program still works, then yes, that code was optional.

.strip() with no arguments (or None as the first argument) removes all whitespace at the start and end, including spaces, tabs, newlines and carriage returns. Leaving it in doesn't do any harm, and allows your program to deal with unexpected extra whitespace inserted into the file.

For example, by using .strip(), the following two lines in a file would lead to the same end result:

 foo\tbar \n
foo\tbar\n

I'd say leave it in.

You can simply use format() to achieve this:

format(3.140, '.10g') where 10 is the precision you want.

You want the :checkbox:checked selector and map to create an array of the values:

var checkedValues = $('input:checkbox:checked').map(function() {
    return this.value;
}).get();

If your checkboxes have a shared class it would be faster to use that instead, eg. $('.mycheckboxes:checked'), or for a common name $('input[name="Foo"]:checked')

- Update -

If you don't need IE support then you can now make the map() call more succinct by using an arrow function:

var checkedValues = $('input:checkbox:checked').map((i, el) => el.value).get();

If you want to first take mean on the combination of ['cluster', 'org'] and then take mean on cluster groups, you can use:

In [59]: (df.groupby(['cluster', 'org'], as_index=False).mean()
            .groupby('cluster')['time'].mean())
Out[59]:
cluster
1          15
2          54
3           6
Name: time, dtype: int64

If you want the mean of cluster groups only, then you can use:

In [58]: df.groupby(['cluster']).mean()
Out[58]:
              time
cluster
1        12.333333
2        54.000000
3         6.000000

You can also use groupby on ['cluster', 'org'] and then use mean():

In [57]: df.groupby(['cluster', 'org']).mean()
Out[57]:
               time
cluster org
1       a    438886
        c        23
2       d      9874
        h        34
3       w         6

Well, Apache is HTTP webserver, where as Tomcat is also webserver for Servlets and JSP. Moreover Apache is preferred over Apache Tomcat in real time

The easy way to do it is to use background-image then just put an <img> in that element.

The other way to do is using css layers. There is a ton a resources available to help you with this, just search for css layers.

Sed!

Given template.txt:

The number is ${i}
The word is ${word}

we just have to say:

sed -e "s/\${i}/1/" -e "s/\${word}/dog/" template.txt

Thanks to Jonathan Leffler for the tip to pass multiple -e arguments to the same sed invocation.

I think your professor is trying to stop a bad habit before it even starts.

Global variables have their place and like many people said knowing where and when to use them can be complicated. So I think rather than get into the nitty gritty of the why, how, when, and where of global variables your professor decided to just ban. Who knows, he might un-ban them in the future.

Try this:

data = f.flatMap(lambda x: x.split(' '))
map = data.map(lambda x: (x, 1))
mapreduce = map.reduceByKey(lambda x,y: x+y)
result = mapreduce.collect()

Please note that when you run collect(), the RDD - which is a distributed data set is aggregated at the driver node and is essentially converted to a list. So obviously, it won't be a good idea to collect() a 2T data set. If all you need is a couple of samples from your RDD, use take(10).

Leveraging the power of java.util.Optional#map():

List<Car> requiredCars = cars.stream()
  .filter (car -> 
    Optional.ofNullable(car)
      .map(Car::getName)
      .map(name -> name.startsWith("M"))
      .orElse(false) // what to do if either car or getName() yields null? false will filter out the element
    )
  .collect(Collectors.toList())
;

Just add:

import os

in the beginning, before:

from settings import PROJECT_ROOT

This will import the python's module os, which apparently is used later in the code of your module without being imported.

Simple code to implement ReCaptcha v3

The basic JS code

<script src="https://www.google.com/recaptcha/api.js?render=your reCAPTCHA site key here"></script>
<script>
    grecaptcha.ready(function() {
    // do request for recaptcha token
    // response is promise with passed token
        grecaptcha.execute('your reCAPTCHA site key here', {action:'validate_captcha'})
                  .then(function(token) {
            // add token value to form
            document.getElementById('g-recaptcha-response').value = token;
        });
    });
</script>

The basic HTML code

<form id="form_id" method="post" action="your_action.php">
    <input type="hidden" id="g-recaptcha-response" name="g-recaptcha-response">
    <input type="hidden" name="action" value="validate_captcha">
    .... your fields
</form>

The basic PHP code

if (isset($_POST['g-recaptcha-response'])) {
    $captcha = $_POST['g-recaptcha-response'];
} else {
    $captcha = false;
}

if (!$captcha) {
    //Do something with error
} else {
    $secret   = 'Your secret key here';
    $response = file_get_contents(
        "https://www.google.com/recaptcha/api/siteverify?secret=" . $secret . "&response=" . $captcha . "&remoteip=" . $_SERVER['REMOTE_ADDR']
    );
    // use json_decode to extract json response
    $response = json_decode($response);

    if ($response->success === false) {
        //Do something with error
    }
}

//... The Captcha is valid you can continue with the rest of your code
//... Add code to filter access using $response . score
if ($response->success==true && $response->score <= 0.5) {
    //Do something to denied access
}

You have to filter access using the value of $response.score. It can takes values from 0.0 to 1.0, where 1.0 means the best user interaction with your site and 0.0 the worst interaction (like a bot). You can see some examples of use in ReCaptcha documentation.

You can use Command prompt for VS 2010 and then select the path that your boost located. Use "bootstrap.bat", you can successfully install it.

Try... csv download.

<?php 
mysql_connect('hostname', 'username', 'password');
mysql_select_db('dbname');
$qry = mysql_query("SELECT * FROM tablename");
$data = "";
while($row = mysql_fetch_array($qry)) {
  $data .= $row['field1'].",".$row['field2'].",".$row['field3'].",".$row['field4']."\n";
}

header('Content-Type: application/csv');
header('Content-Disposition: attachment; filename="filename.csv"');
echo $data; exit();
?>

$("#myAudioElement")[0].play();

It doesn't work with $("#myAudioElement").play() like you would expect. The official reason is that incorporating it into jQuery would add a play() method to every single element, which would cause unnecessary overhead. So instead you have to refer to it by its position in the array of DOM elements that you're retrieving with $("#myAudioElement"), aka 0.

This quote is from a bug that was submitted about it, which was closed as "feature/wontfix":

To do that we'd need to add a jQuery method name for each DOM element method name. And of course that method would do nothing for non-media elements so it doesn't seem like it would be worth the extra bytes it would take.

This works using java.util.Scanner and will take multiple "enter" keystrokes:

    Scanner scanner = new Scanner(System.in);
    String readString = scanner.nextLine();
    while(readString!=null) {
        System.out.println(readString);

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }
    }

To break it down:

Scanner scanner = new Scanner(System.in);
String readString = scanner.nextLine();

These lines initialize a new Scanner that is reading from the standard input stream (the keyboard) and reads a single line from it.

    while(readString!=null) {
        System.out.println(readString);

While the scanner is still returning non-null data, print each line to the screen.

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

If the "enter" (or return, or whatever) key is supplied by the input, the nextLine() method will return an empty string; by checking to see if the string is empty, we can determine whether that key was pressed. Here the text Read Enter Key is printed, but you could perform whatever action you want here.

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }

Finally, after printing the content and/or doing something when the "enter" key is pressed, we check to see if the scanner has another line; for the standard input stream, this method will "block" until either the stream is closed, the execution of the program ends, or further input is supplied.

Use following codes to read the file

import java.io.File;
import java.util.Scanner;

public class ReadFile {

    public static void main(String[] args) {

        try {
            System.out.print("Enter the file name with extension : ");

            Scanner input = new Scanner(System.in);

            File file = new File(input.nextLine());

            input = new Scanner(file);


            while (input.hasNextLine()) {
                String line = input.nextLine();
                System.out.println(line);
            }
            input.close();

        } catch (Exception ex) {
            ex.printStackTrace();
        }
    }

}

-> This application is printing the file content line by line

In a Jupyter Notebook

As long as you're working in a Jupyter Notebook, this short solution might be useful:

%cd ..
import nib

It works even without an __init__.py file.

I tested it with Anaconda3 on Linux and Windows 7.

James Padolsey created a wonderful filter that allows regex to be used for selection.

Say you have the following div:

<div class="asdf">

Padolsey's :regex filter can select it like so:

$("div:regex(class, .*sd.*)")

Also, check the official documentation on selectors.

UPDATE: : syntax Deprecation JQuery 3.0

Since jQuery.expr[':'] used in Padolsey's implementation is already deprecated and will render a syntax error in the latest version of jQuery, here is his code adapted to jQuery 3+ syntax:

jQuery.expr.pseudos.regex = jQuery.expr.createPseudo(function (expression) {
    return function (elem) {
        var matchParams = expression.split(','),
            validLabels = /^(data|css):/,
            attr = {
                method: matchParams[0].match(validLabels) ?
                    matchParams[0].split(':')[0] : 'attr',
                property: matchParams.shift().replace(validLabels, '')
            },
            regexFlags = 'ig',
            regex = new RegExp(matchParams.join('').replace(/^\s+|\s+$/g, ''), regexFlags);
        return regex.test(jQuery(elem)[attr.method](attr.property));
    }
});

I had a problem like this when I deleted a folder (and sub-folders) and went to recreate them from scratch. You get this error from manually deleting and re-adding folders (whereas files seem to cope OK with this).

After some frustrating messing around, found I had to:
(using TortoiseSVN on Windows)

1. Move conflicting folders out of working copy (so that I don't lose my work-in-progress)
2. Do an svn update which added old files/folders back into working copy
3. svn delete folder
4. commit
5. Copy new folder back into working copy (ensuring you delete all the .svn folders inside)
6. commit

Unfortunately it (A) requires two commits, and (B) loses file revision history as it only tracks back to the recent re-add (unless someone can explain how to fix this). An alternative solution that works around these 2 issues is to skip steps 3 and 4, the only problem being that old/unnecessary files may still be present in your directory. You could delete these manually.

Would love to hear any additional insights others might have on this.

Simon.

[Update] OK, I had this same problem again just then, but the offending folder was NOT in the last commit, so an update didn't restore it. Instead I had to browse the repository and delete the offending folder. I could then add the folder back in and commit successfully.

How about:

String.prototype.strcmp = function(s) {
    if (this < s) return -1;
    if (this > s) return 1;
    return 0;
}

Then, to compare s1 with 2:

s1.strcmp(s2)

If you want to know how to read a file, within a directory, and do something with it, here you go. This also shows you how to run a command through the power shell. This is in TypeScript! I had trouble with this, so I hope this helps someone one day. Feel free to down vote me if you think its THAT unhelpful. What this did for me was webpack all of my .ts files in each of my directories within a certain folder to get ready for deployment. Hope you can put it to use!

import * as fs from 'fs';
let path = require('path');
let pathDir = '/path/to/myFolder';
const execSync = require('child_process').execSync;

let readInsideSrc = (error: any, files: any, fromPath: any) => {
    if (error) {
        console.error('Could not list the directory.', error);
        process.exit(1);
    }

    files.forEach((file: any, index: any) => {
        if (file.endsWith('.ts')) {
            //set the path and read the webpack.config.js file as text, replace path
            let config = fs.readFileSync('myFile.js', 'utf8');
            let fileName = file.replace('.ts', '');
            let replacedConfig = config.replace(/__placeholder/g, fileName);

            //write the changes to the file
            fs.writeFileSync('myFile.js', replacedConfig);

            //run the commands wanted
            const output = execSync('npm run scriptName', { encoding: 'utf-8' });
            console.log('OUTPUT:\n', output);

            //rewrite the original file back
            fs.writeFileSync('myFile.js', config);
        }
    });
};

// loop through all files in 'path'
let passToTest = (error: any, files: any) => {
    if (error) {
        console.error('Could not list the directory.', error);
        process.exit(1);
    }

    files.forEach(function (file: any, index: any) {
        let fromPath = path.join(pathDir, file);
        fs.stat(fromPath, function (error2: any, stat: any) {
            if (error2) {
                console.error('Error stating file.', error2);
                return;
            }

            if (stat.isDirectory()) {
                fs.readdir(fromPath, (error3: any, files1: any) => {
                    readInsideSrc(error3, files1, fromPath);
                });
            } else if (stat.isFile()) {
                //do nothing yet
            }

        });
    });
};

//run the bootstrap
fs.readdir(pathDir, passToTest);

I don't think you can use braces.

According to the Bash manual about case in Conditional Constructs.

Each pattern undergoes tilde expansion, parameter expansion, command substitution, and arithmetic expansion.

Nothing about Brace Expansion unfortunately.

So you'd have to do something like this:

case $1 in
    req*)
        ...
        ;;
    met*|meet*)
        ...
        ;;
    *)
        # You should have a default one too.
esac

In general, you either have to specify $(OBJDIR) on the left hand side of all the rules that place files in $(OBJDIR), or you can run make from $(OBJDIR). VPATH is for sources, not for objects.

Take a look at these two links for more explanation, and a "clever" workaround.

You can actually do what Chris Chalmers does in his answer, but you must make sure that HAML doesn't parse the JavaScript. This approach is actually useful when you need to use a different type than text/javascript, which is was I needed to do for MathJax.

You can use the plain filter to keep HAML from parsing the script and throwing an illegal nesting error:

%script{type: "text/x-mathjax-config"}
  :plain
    MathJax.Hub.Config({
      tex2jax: {
        inlineMath: [["$","$"],["\\(","\\)"]]
      }
    });

You shouldn't use float unless you have to. In 99% of cases, double is a better choice.

int x = 1111111111;
int y = 10000;
float f = (float) x / y;
double d = (double) x / y;
System.out.println("f= "+f);
System.out.println("d= "+d);

prints

f= 111111.12
d= 111111.1111

Following @Matt's comment.

float has very little precision (6-7 digits) and shows significant rounding error fairly easily. double has another 9 digits of accuracy. The cost of using double instead of float is notional in 99% of cases however the cost of a subtle bug due to rounding error is much higher. For this reason, many developers recommend not using floating point at all and strongly recommend BigDecimal.

However I find that double can be used in most cases provided sensible rounding is used.

In this case, int x has 32-bit precision whereas float has a 24-bit precision, even dividing by 1 could have a rounding error. double on the other hand has 53-bit of precision which is more than enough to get a reasonably accurate result.

You should be able to set these via the attr() or prop() functions in jQuery as shown below:

jQuery (< 1.7):

// This will disable just the div
$("#dcacl").attr('disabled','disabled');

or

// This will disable everything contained in the div
$("#dcacl").children().attr("disabled","disabled");

jQuery (>= 1.7):

// This will disable just the div
$("#dcacl").prop('disabled',true);

or

// This will disable everything contained in the div
$("#dcacl").children().prop('disabled',true);

or

//  disable ALL descendants of the DIV
$("#dcacl *").prop('disabled',true);

Javascript:

// This will disable just the div
document.getElementById("dcalc").disabled = true;

or

// This will disable all the children of the div
var nodes = document.getElementById("dcalc").getElementsByTagName('*');
for(var i = 0; i < nodes.length; i++){
     nodes[i].disabled = true;
}

You have leaked connections on your code. You may try to use using to certify that you're closing them.

using (SqlConnection sqlconnection1 = new SqlConnection(“Server=.\\SQLEXPRESS ;Integrated security=sspi;connection timeout=5”)) 
{
    sqlconnection1.Open();
    SqlCommand sqlcommand1 = sqlconnection1.CreateCommand();
    sqlcommand1.CommandText = “raiserror (‘This is a fake exception’, 17,1)”;
    sqlcommand1.ExecuteNonQuery();  //this throws a SqlException every time it is called.
    sqlconnection1.Close(); //Still never gets called.
} // Here sqlconnection1.Dispose is _guaranteed_

Better is to Make a global Constants class to save key or variables to fetch or save data.

To save data call this method to save data from every where.

public static void saveData(Context con, String variable, String data)
{
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(con);
    prefs.edit().putString(variable, data).commit();
}

Use it to get data.

public static String getData(Context con, String variable, String defaultValue)
{
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(con);
    String data = prefs.getString(variable, defaultValue);
    return data;
}

and a method something like this will do the trick

public static User getUserInfo(Context con)
{
    String id =  getData(con, Constants.USER_ID, null);
    String name =  getData(con, Constants.USER_NAME, null);
    if(id != null && name != null)
    {
            User user = new User(); //Hope you will have a user Object.
            user.setId(id);
            user.setName(name);
            //Here set other credentials.
            return user;
    }
    else
    return null;
}

Yes, Json.Net is what you need. You basically want to deserialize a Json string into an array of objects.

See their examples:

string myJsonString = @"{
  "Name": "Apple",
  "Expiry": "\/Date(1230375600000+1300)\/",
  "Price": 3.99,
  "Sizes": [
    "Small",
    "Medium",
    "Large"
  ]
}";

// Deserializes the string into a Product object
Product myProduct = JsonConvert.DeserializeObject<Product>(myJsonString);

I would use VMs. Create an XP (or whatever) VM using VMware Workstation or similar product, and snapshot it. That is your oldest version. Then perform the upgrades one at a time, and snapshot each time. Then you can switch to any snapshot you need later, or clone independent VMs based on all the snapshots so you can run them all at once. You probably want to test on different operating systems as well as different versions, so VMs generalize that solution as well rather than some one-off solution of hacking multiple IEs to coexist on a single instance of Windows.

$dt = '2017-Jan-10';
         OR
$dt = '2017-January-10';

echo date('Y-m-d', strtotime($dt));

echo date('Y/m/d', strtotime($dt));

A view is a virtual table. A view consists of rows and columns just like a table. The difference between a view and a table is that views are definitions built on top of other tables (or views), and do not hold data themselves. If data is changing in the underlying table, the same change is reflected in the view. A view can be built on top of a single table or multiple tables. It can also be built on top of another view. In the SQL Create View page, we will see how a view can be built.

Views offer the following advantages:

1. Ease of use: A view hides the complexity of the database tables from end users. Essentially we can think of views as a layer of abstraction on top of the database tables.

2. Space savings: Views takes very little space to store, since they do not store actual data.

3. Additional data security: Views can include only certain columns in the table so that only the non-sensitive columns are included and exposed to the end user. In addition, some databases allow views to have different security settings, thus hiding sensitive data from prying eyes.

Answer from:http://www.1keydata.com/sql/sql-view.html

In the documentation it's stated: Use the prefix option together with the global option:

The prefix config defaults to the location where node is installed. On most systems, this is /usr/local. On windows, this is the exact location of the node.exe binary. On Unix systems, it's one level up, since node is typically installed at {prefix}/bin/node rather than {prefix}/node.exe.

When the global flag is set, npm installs things into this prefix. When it is not set, it uses the root of the current package, or the current working directory if not in a package already.

(Emphasis by them)

So in your root directory you could install with

npm install --prefix <path/to/prefix_folder> -g

and it will install the node_modules folder into the folder

<path/to/prefix_folder>/lib/node_modules

I think with async, it is possible to have a more elegant solution and not having deadlocks even when using both standardOutput and standardError:

using (Process process = new Process())
{
    process.StartInfo.FileName = filename;
    process.StartInfo.Arguments = arguments;
    process.StartInfo.UseShellExecute = false;
    process.StartInfo.RedirectStandardOutput = true;
    process.StartInfo.RedirectStandardError = true;

    process.Start();

    var tStandardOutput = process.StandardOutput.ReadToEndAsync();
    var tStandardError = process.StandardError.ReadToEndAsync();

    if (process.WaitForExit(timeout))
    {
        string output = await tStandardOutput;
        string errors = await tStandardError;

        // Process completed. Check process.ExitCode here.
    }
    else
    {
        // Timed out.
    }
}

It is base on Mark Byers answer. If you are not in an async method, you can use string output = tStandardOutput.result; instead of await

Python IndentationError unindent does not match any outer indentation level

# usr/bin/bash -tt

or

# usr/bin/python -tt

Use:

struct arg_struct *args = malloc(sizeof(struct arg_struct));

And pass this arguments like this:

pthread_create(&tr, NULL, print_the_arguments, (void *)args);

Don't forget free args! ;)

Here the code to use your app.js

input specifies file name

res.download(__dirname+'/'+input);

I got this error for my Linux Jenkins slave. I fixed it by changing from the node from "Known hosts file Verification Strategy" to "Non verifying Verification Strategy".

You're missing a GROUP BY clause:

SELECT news.id, users.username, news.title, news.date, news.body, COUNT(comments.id)
FROM news
LEFT JOIN users
ON news.user_id = users.id
LEFT JOIN comments
ON comments.news_id = news.id
GROUP BY news.id

The left join is correct. If you used an INNER or RIGHT JOIN then you wouldn't get news items that didn't have comments.

For this to work, your font also needs to be set to monospace.
If you think about it, lines can't otherwise line up perfectly perfectly.

This answer is detailed at sublime text forum:
http://www.sublimetext.com/forum/viewtopic.php?f=3&p=42052
This answer has links for choosing an appropriate font for your OS,
and gives an answer to an edge case of fonts not lining up.

Another website that lists great monospaced free fonts for programmers. http://hivelogic.com/articles/top-10-programming-fonts

On stackoverflow, see:

Michael Ruth's answer here: How to make ruler always be shown in Sublime text 2?

MattDMo's answer here: What is the default font of Sublime Text?

I have rulers set at the following:
30
50 (git commit message titles should be limited to 50 characters)
72 (git commit message details should be limited to 72 characters)
80 (Windows Command Console Window maxes out at 80 character width)

Other viewing environments that benefit from shorter lines: github: there is no word wrap when viewing a file online
So, I try to keep .js .md and other files at 70-80 characters.
Windows Console: 80 characters.

try this:

import datetime
from datetime import datetime as dt

today_date = datetime.date.today()
date_time = dt.strptime(date_time_string, '%Y-%m-%d %H:%M')

strp() doesn't exist. I think you mean strptime.

Based on the comments left above I ran this under sqlplus instead of SQL Developer and the UPDATE statement ran perfectly, leaving me to believe this is an issue in SQL Developer particularly as there was no ORA error number being returned. Thank you for leading me in the right direction.

This exact question is answered on mySql workbench-faq:

Hover over an acronym to view a description, and see the Section 8.1.11.2, “The Columns Tab” and MySQL CREATE TABLE documentation for additional details.

That means hover over an acronym in the mySql Workbench table editor.

Section 8.1.11.2, “The Columns Tab”

The following works for me:

public virtual void Send(string fileName, byte[] file)
{
    ByteArrayToFile(fileName, file);

    var request = (FtpWebRequest) WebRequest.Create(new Uri(ServerUrl + fileName));

    request.Method = WebRequestMethods.Ftp.UploadFile;
    request.UsePassive = false;
    request.Credentials = new NetworkCredential(UserName, Password);
    request.ContentLength = file.Length;

    var requestStream = request.GetRequestStream();
    requestStream.Write(file, 0, file.Length);
    requestStream.Close();

    var response = (FtpWebResponse) request.GetResponse();

    if (response != null)
        response.Close();
}

You can't read send the file parameter in your code as it is only the filename.

Use the following:

byte[] bytes = File.ReadAllBytes(dir + file);

To get the file so you can pass it to the Send method.

Base class constructors are automatically called for you if they have no argument. If you want to call a superclass constructor with an argument, you must use the subclass's constructor initialization list. Unlike Java, C++ supports multiple inheritance (for better or worse), so the base class must be referred to by name, rather than "super()".

class SuperClass
{
    public:

        SuperClass(int foo)
        {
            // do something with foo
        }
};

class SubClass : public SuperClass
{
    public:

        SubClass(int foo, int bar)
        : SuperClass(foo)    // Call the superclass constructor in the subclass' initialization list.
        {
            // do something with bar
        }
};

More info on the constructor's initialization list here and here.

I came to this site looking for an easy way to copy without changing cell references. But now I thnk my own workaround is simpler than most of these methods. My method relies on the fact that Copy changes references but Move doesn't. Here's a simple example.

Assume you have raw data in columns A and B, and a formula in C (e.g. C=A+B) and you want the same formula in column F but Copying from C to F leads to F=D+E.

1. Copy contents of C to any empty temporary column, say R. The relative references will change to R=P+Q but ignore this even if it's flagged as an error.
2. Go back to C and Move (not Copy) it to F. Formula should be unchanged so F=A+B.
3. Now go to R and copy it back to C. Relative reference will revert to C=A+B
4. Delete the temporary formula in R.
5. Bob's your uncle.

I've done this with a range of cells so I imagine it would work with virtually any level of complexity. You just need an empty area to park the coiped cells. And of course you have to remember where you left them.

The type char is a primitive -- not an object -- so it cannot be dereferenced

Dereferencing is the process of accessing the value referred to by a reference. Since a char is already a value (not a reference), it can not be dereferenced.

use Character class:

if(Character.isLetter(c)) {

This has been mentioned in other questions, but ctrl + [ is an equivalent to ESC on all keyboards.

In early versions of C, all structure declarations would share a common set of fields. Given:

struct x {int x_mode; int q; float x_f};
struct y {int y_mode; int q; int y_l};
struct z {int z_mode; char name[20];};

a compiler would essentially produce a table of structures' sizes (and possibly alignments), and a separate table of structures' members' names, types, and offsets. The compiler didn't keep track of which members belonged to which structures, and would allow two structures to have a member with the same name only if the type and offset matched (as with member q of struct x and struct y). If p was a pointer to any structure type, p->q would add the offset of "q" to pointer p and fetch an "int" from the resulting address.

Given the above semantics, it was possible to write a function that could perform some useful operations on multiple kinds of structure interchangeably, provided that all the fields used by the function lined up with useful fields within the structures in question. This was a useful feature, and changing C to validate members used for structure access against the types of the structures in question would have meant losing it in the absence of a means of having a structure that can contain multiple named fields at the same address. Adding "union" types to C helped fill that gap somewhat (though not, IMHO, as well as it should have been).

An essential part of unions' ability to fill that gap was the fact that a pointer to a union member could be converted into a pointer to any union containing that member, and a pointer to any union could be converted to a pointer to any member. While the C89 Standard didn't expressly say that casting a T* directly to a U* was equivalent to casting it to a pointer to any union type containing both T and U, and then casting that to U*, no defined behavior of the latter cast sequence would be affected by the union type used, and the Standard didn't specify any contrary semantics for a direct cast from T to U. Further, in cases where a function received a pointer of unknown origin, the behavior of writing an object via T*, converting the T* to a U*, and then reading the object via U* would be equivalent to writing a union via member of type T and reading as type U, which would be standard-defined in a few cases (e.g. when accessing Common Initial Sequence members) and Implementation-Defined (rather than Undefined) for the rest. While it was rare for programs to exploit the CIS guarantees with actual objects of union type, it was far more common to exploit the fact that pointers to objects of unknown origin had to behave like pointers to union members and have the behavioral guarantees associated therewith.

Other possible way is:

echo "text" | tee -a filename >/dev/null

The -a will append at the end of the file.

If needing sudo, use:

echo "text" | sudo tee -a filename >/dev/null

The 4K limit you read about is for the entire cookie, including name, value, expiry date etc. If you want to support most browsers, I suggest keeping the name under 4000 bytes, and the overall cookie size under 4093 bytes.

One thing to be careful of: if the name is too big you cannot delete the cookie (at least in JavaScript). A cookie is deleted by updating it and setting it to expire. If the name is too big, say 4090 bytes, I found that I could not set an expiry date. I only looked into this out of interest, not that I plan to have a name that big.

To read more about it, here are the "Browser Cookie Limits" for common browsers.

While on the subject, if you want to support most browsers, then do not exceed 50 cookies per domain, and 4093 bytes per domain. That is, the size of all cookies should not exceed 4093 bytes.

This means you can have 1 cookie of 4093 bytes, or 2 cookies of 2045 bytes, etc.

I used to say 4095 bytes due to IE7, however now Mobile Safari comes in with 4096 bytes with a 3 byte overhead per cookie, so 4093 bytes max.

Usually you already know the extension, so you might wish to use:

basename filename .extension

for example:

basename /path/to/dir/filename.txt .txt

and we get

filename
