Simply call list on the generator.

lst = list(gen)
lst

Be aware that this affects the generator which will not return any further items.

You also cannot directly call list in IPython, as it conflicts with a command for listing lines of code.

Tested on this file:

def gen():
    yield 1
    yield 2
    yield 3
    yield 4
    yield 5
import ipdb
ipdb.set_trace()

g1 = gen()

text = "aha" + "bebe"

mylst = range(10, 20)

which when run:

$ python code.py 
> /home/javl/sandbox/so/debug/code.py(10)<module>()
      9 
---> 10 g1 = gen()
     11 

ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
     11 
---> 12 text = "aha" + "bebe"
     13 

ipdb> lst = list(g1)
ipdb> lst
[1, 2, 3, 4, 5]
ipdb> q
Exiting Debugger.

General method for escaping function/variable/debugger name conflicts

There are debugger commands p and pp that will print and prettyprint any expression following them.

So you could use it as follows:

$ python code.py 
> /home/javl/sandbox/so/debug/code.py(10)<module>()
      9 
---> 10 g1 = gen()
     11 

ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
     11 
---> 12 text = "aha" + "bebe"
     13 

ipdb> p list(g1)
[1, 2, 3, 4, 5]
ipdb> c

There is also an exec command, called by prefixing your expression with !, which forces debugger to take your expression as Python one.

ipdb> !list(g1)
[]

For more details see help p, help pp and help exec when in debugger.

ipdb> help exec
(!) statement
Execute the (one-line) statement in the context of
the current stack frame.
The exclamation point can be omitted unless the first word
of the statement resembles a debugger command.
To assign to a global variable you must always prefix the
command with a 'global' command, e.g.:
(Pdb) global list_options; list_options = ['-l']

There is a php library (pdfparser) that does exactly what you want.

project website

http://www.pdfparser.org/

github

https://github.com/smalot/pdfparser

Demo page/api

http://www.pdfparser.org/demo

After including pdfparser in your project you can get all text from mypdf.pdf like so:

<?php
$parser = new \installpath\PdfParser\Parser();
$pdf    = $parser->parseFile('mypdf.pdf');  
$text = $pdf->getText();
echo $text;//all text from mypdf.pdf

?>

Simular you can get the metadata from the pdf as wel as getting the pdf objects (for example images).

Specify the maxrecursion option at the end of the query:

...
from EmployeeTree
option (maxrecursion 0)

That allows you to specify how often the CTE can recurse before generating an error. Maxrecursion 0 allows infinite recursion.

You don't have to convert the object to a MyClass object because it already is. Wnat you really want to do is to cast it, but since the class name is not known at compile time, you can't do that, since you can't declare a variable of that class. My guess is that you want/need something like "duck typing", i.e. you don't know the class name but you know the method name at compile time. Interfaces, as proposed by Gregory, are your best bet to do that.

If you are converting string to float:

import re
A1 = [' "29.0" ',' "65.2" ',' "75.2" ']
float_values = [float(re.search(r'\d+.\d+',number).group()) for number in A1]
print(float_values)
>>> [29.0, 65.2, 75.2]

Insert command tree in bash.

Also, there is a DOS comnand "tree". You can displays directory paths and files in each subdirectory with command:

tree /F

https://web.csulb.edu/~murdock/tree.html

By default there will be no branches listed and pops up only after some file is placed. You don't have to worry much about it. Just run all your commands like creating folder structures, adding/deleting files, commiting files, pushing it to server or creating branches. It works seamlessly without any issue.

https://git-scm.com/docs

An important note: JavaScript Arrays are not associative arrays like those you might be used to from PHP. If your "array key" is a string, you're no longer operating on the contents of an array. Your array is an object, and you're using bracket notation to access the member named <key name>. Thus:

var myArray = [];
myArray["bar"] = true;
myArray["foo"] = true;
alert(myArray.length); // returns 0.

because you have not added elements to the array, you have only modified myArray's bar and foo members.

One shouldn't use the using directive at the global scope, especially in headers. However, there are situations where it is appropriate even in a header file:

template <typename FloatType> inline
FloatType compute_something(FloatType x)
{
    using namespace std; // No problem since scope is limited
    return exp(x) * (sin(x) - cos(x * 2) + sin(x * 3) - cos(x * 4));
}

This is better than explicit qualification (std::sin, std::cos...), because it is shorter and has the ability to work with user defined floating point types (via argument-dependent lookup (ADL)).

Short answer: you can't. AngularJS won't allow you to inject services into the config because it can't be sure they have been loaded correctly.

See this question and answer: AngularJS dependency injection of value inside of module.config

A module is a collection of configuration and run blocks which get applied to the application during the bootstrap process. In its simplest form the module consist of collection of two kinds of blocks:

Configuration blocks - get executed during the provider registrations and configuration phase. Only providers and constants can be injected into configuration blocks. This is to prevent accidental instantiation of services before they have been fully configured.

You can do this if you use an <a> tag instead of a button. I know it's not exactly what you asked for, but it might give you some other options if you cannot find a solution to this:

Borrowing from a demo from another answer here I produced this:

a {_x000D_
  display: block;_x000D_
  font-size: 18px;_x000D_
  border: 2px solid gray;_x000D_
  border-radius: 100px;_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
  text-align: center;_x000D_
  line-height: 100px;_x000D_
}_x000D_
_x000D_
a:active {_x000D_
  font-size: 18px;_x000D_
  border: 2px solid green;_x000D_
  border-radius: 100px;_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
}_x000D_
_x000D_
a:target {_x000D_
  font-size: 18px;_x000D_
  border: 2px solid red;_x000D_
  border-radius: 100px;_x000D_
  width: 100px;_x000D_
  height: 100px;_x000D_
}

<a id="btn" href="#btn">Demo</a>

Notice the use of :target; this will be the style applied when the element is targeted via the hash. Which also means your HTML will need to be this: <a id="btn" href="#btn">Demo</a> a link targeting itself. and the demo http://jsfiddle.net/rlemon/Awdq5/4/

Thanks to @BenjaminGruenbaum here is a better demo: http://jsfiddle.net/agzVt/

_{Also, as a footnote: this should really be done with JavaScript and applying / removing CSS classes from the element. It would be much less convoluted.}

//1 year from today's date
echo date('d-m-Y', strtotime('+1 year'));

//1 year from from specific date
echo date('22-09-Y', strtotime('+1 year'));

hope this simpler bit of code helps someone in future :)

If with the word "anywhere" you mean without having an explicit Context (for example from a background thread) you should define a class in your project like:

public class MyApp extends Application {
    private static MyApp instance;

    public static MyApp getInstance() {
        return instance;
    }

    public static Context getContext(){
        return instance;
        // or return instance.getApplicationContext();
    }

    @Override
    public void onCreate() {
        instance = this;
        super.onCreate();
    }
}

Then in your manifest you need to add this class to the Name field at the Application tab. Or edit the xml and put

<application
    android:name="com.example.app.MyApp"
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    .......
    <activity
        ......

and then from anywhere you can call

String packagename= MyApp.getContext().getPackageName();

Hope it helps.

you can use between too:

SELECT Table.date
  FROM Table 
  WHERE date between current_date and current_date - interval '10 day';

I would tentatively recommend using PDO for your SQL access.

Then it is only a case of changing the driver and ensuring the SQL works on the new backend. In theory. Data migration is a different issue.

Abstract database access is great.

Follow the screen shots

you are ready to Go!

a += b is shorthand for a = a +b which means:

1) 1 += 2 // won't compile

2) 15

The problem is that $money is an array and you are treating it like a string or a variable which can be easily converted to string. You should say something like:

 '.... Money:'.$money['money']

Be sure to serve up the file without a no-cache header! IE has issues with this, if user tries to "open" the download without saving first.

While createting the bat file, you can easly avoid the space. If you want to mentioned "program files "folder in batch file.

Do following steps:

1. Type c: then press enter

2. cd program files

3. cd "choose your own folder name"

then continue as you wish.

This way you can create batch file and you can mention program files folder.

If you are using Eclipse then you can do this by specifying the required size for the particular application in its Run Configuration's VM Arguments as EX: -Xms128m -Xmx512m

Or if you want all applications running from your eclipse to have the same specified size then you can specify this in the eclipse.ini file which is present in your Eclipse home directory.

To get the size of the JVM during Runtime you can use Runtime.totalMemory() which returns the total amount of memory in the Java virtual machine, measured in bytes.

I have read multiple threads and none of them fixed the issue that people are describing and I have experienced too.

I have even tried to move away from conda and use pip, to upgrade to python 3.7, i have tried all coding proposed and none of them fixed.

And here is why (the problem):

by default python/flask search the static and the template in a folder structure like:

/Users/username/folder_one/folder_two/ProjectName/src/app_name/<static>
 and 
/Users/username/folder_one/folder_two/ProjectName/src/app_name/<template>

you can verify by yourself using the debugger on Pycharm (or anything else) and check the values on the app (app = Flask(name)) and search for teamplate_folder and static_folder

in order to fix this, you have to specify the values when creating the app something like this:

TEMPLATE_DIR = os.path.abspath('../templates')
STATIC_DIR = os.path.abspath('../static')

# app = Flask(__name__) # to make the app run without any
app = Flask(__name__, template_folder=TEMPLATE_DIR, static_folder=STATIC_DIR)

the path TEMPLATE_DIR and STATIC_DIR depend on where the file app is located. in my case, see the picture, it was located within a folder under src.

you can change the template and static folders as you wish and register on the app = Flask...

In truth, I have started experiencing the problem when messing around with folder and at times worked at times not. this fixes the problem once and for all

the html code looks like this:

<link href="{{ url_for('static', filename='libraries/css/bootstrap.css') }}" rel="stylesheet" type="text/css" >

This the code

Here the structure of the folders

You can refer in this line - Difference between ASP.NET Core (.NET Core) and ASP.NET Core (.NET Framework)

Xamarin is not a debate at all. When you want to build mobile (iOS, Android, and Windows Mobile) apps using C#, Xamarin is your only choice.

The .NET Framework supports Windows and Web applications. Today, you can use Windows Forms, WPF, and UWP to build Windows applications in .NET Framework. ASP.NET MVC is used to build Web applications in .NET Framework.

.NET Core is the new open-source and cross-platform framework to build applications for all operating system including Windows, Mac, and Linux. .NET Core supports UWP and ASP.NET Core only. UWP is used to build Windows 10 targets Windows and mobile applications. ASP.NET Core is used to build browser based web applications.

Since the java.sql.Date has a constructor that takes 'long time' and java.util.Date has a method that returns 'long time', I just pass the returned 'long time' to the java.sql.Date to create the date.

java.util.Date date = new java.util.Date();
java.sql.Date sqlDate = new Date(date.getTime());

It looks like API level 11 has support for what you need. See WebViewClient.shouldInterceptRequest().

My problem wasn't that the connection string I was providing was wrong, or that the connection string in the app.config I thought I was using was wrong, but that I was using the wrong app.config.

This is intended behavior.

When you make an HTTP request, the server normally returns code 200 OK. If you set If-Modified-Since, the server may return 304 Not modified (and the response will not have the content). This is supposed to be your cue that the page has not been modified.

The authors of the class have foolishly decided that 304 should be treated as an error and throw an exception. Now you have to clean up after them by catching the exception every time you try to use If-Modified-Since.

Your debut and fin values are floating point values, not integers, because taille is a float.

Make those values integers instead:

item = plateau[int(debut):int(fin)]

Alternatively, make taille an integer:

taille = int(sqrt(len(plateau)))

Here's a quick local task to permanently set key/values on /etc/environment (which is system-wide, all users):

- name: populate /etc/environment
  lineinfile:
    dest: "/etc/environment"
    state: present
    regexp: "^{{ item.key }}="
    line: "{{ item.key }}={{ item.value}}"
  with_items: "{{ os_environment }}"

and the vars for it:

os_environment:
  - key: DJANGO_SETTINGS_MODULE 
    value : websec.prod_settings  
  - key: DJANGO_SUPER_USER 
    value : admin

and, yes, if you ssh out and back in, env shows the new environment variables.

The best approach would be to keep your job configurations in a Jenkinsfile that live in source control.

If the javascript file is loaded from the admin dashboard, this javascript function will give you the root of your WordPress installation. I use this a lot when I'm building plugins that need to make ajax requests from the admin dashboard.

  var index = href.indexOf('/wp-admin');
  var homeUrl = href.substring(0, index);
  return homeUrl;

I had the same issue but managed to resolve it using boto3.client and list_objects_v2 with Bucket and StartAfter parameters.

s3client = boto3.client('s3')
bucket = 'my-bucket-name'
startAfter = 'firstlevelFolder/secondLevelFolder'

theobjects = s3client.list_objects_v2(Bucket=bucket, StartAfter=startAfter )
for object in theobjects['Contents']:
    print object['Key']

The output result for the code above would display the following:

firstlevelFolder/secondLevelFolder/item1
firstlevelFolder/secondLevelFolder/item2

Boto3 list_objects_v2 Documentation

In order to strip out only the directory name for secondLevelFolder I just used python method split():

s3client = boto3.client('s3')
bucket = 'my-bucket-name'
startAfter = 'firstlevelFolder/secondLevelFolder'

theobjects = s3client.list_objects_v2(Bucket=bucket, StartAfter=startAfter )
for object in theobjects['Contents']:
    direcoryName = object['Key'].encode("string_escape").split('/')
    print direcoryName[1]

The output result for the code above would display the following:

secondLevelFolder
secondLevelFolder

Python split() Documentation

If you'd like to get the directory name AND contents item name then replace the print line with the following:

print "{}/{}".format(fileName[1], fileName[2])

And the following will be output:

secondLevelFolder/item2
secondLevelFolder/item2

Hope this helps

I use this method as a wrapper so that I can send parameters. Also using the variables in the top of the method allows it to be minimized at a higher ratio and allows for some code reuse if making multiple similar calls.

function InfoByDate(sDate, eDate){
    var divToBeWorkedOn = "#AjaxPlaceHolder";
    var webMethod = "http://MyWebService/Web.asmx/GetInfoByDates";
    var parameters = "{'sDate':'" + sDate + "','eDate':'" + eDate + "'}";

    $.ajax({
        type: "POST",
        url: webMethod,
        data: parameters,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function(msg) {
            $(divToBeWorkedOn).html(msg.d);
        },
        error: function(e){
            $(divToBeWorkedOn).html("Unavailable");
        }
    });
}

I hope that helps.

Please note that this requires the 3.5 framework to expose JSON webmethods that can be consumed in this manner.

I had a similar problem to solve, here is a simple solution of how to pass variables to template files, the trick is to write the template file taking advantage of the variable. You need to create a dictionary (list is also possible), which holds the set of variables corresponding to each of the file. Then within the template file access them.

see below:

the template file: test_file.j2
# {{ ansible_managed }} created by [email protected]

{% set dkey  = (item | splitext)[0]  %}
{% set fname = test_vars[dkey].name  %}
{% set fip   = test_vars[dkey].ip    %}
{% set fport = test_vars[dkey].port  %}
filename: {{ fname }}
ip address: {{ fip }}
port: {{ fport }}

I solved in this way: I logged in with root username

mysql -u root -p -h localhost

I created a new user with

CREATE USER 'francesco'@'localhost' IDENTIFIED BY 'some_pass';

then I created the database

CREATE DATABASE shop;

I granted privileges for new user for this database

GRANT ALL PRIVILEGES ON shop.* TO 'francesco'@'localhost';

Then I logged out root and logged in new user

quit;
mysql -u francesco -p -h localhost

I rebuilt my database using a script

source shop.sql;

And that's it.. Now from php works without problems with the call

 $conn = new mysqli("localhost", "francesco", "some_pass", "shop");

Thanks to all for your time :)

Is there something that prevents you from merging all revisions on trunk since the last merge?

svn merge -rLastRevisionMergedFromTrunkToBranch:HEAD url/of/trunk path/to/branch/wc

should work just fine. At least if you want to merge all changes on trunk to your branch.

In PowerShell 5 and PowerShell 5 ISE, it is also possible to use just Shift + Enter for multiline editing (instead of standard backticks ` at the end of each line):

PS> &"C:\Program Files\IIS\Microsoft Web Deploy\msdeploy.exe" # Shift+Enter
>>> -verb:sync # Shift+Enter
>>> -source:contentPath="c:\workspace\xxx\master\Build\_PublishedWebsites\xxx.Web" # Shift+Enter
>>> -dest:contentPath="c:\websites\xxx\wwwroot,computerName=192.168.1.1,username=administrator,password=xxx"

It's quite simple, actually. Create a new resource file, for example Strings.resx. Set Access Modifier to Public. Use the apprioriate file template, so Visual Studio will automatically generate an accessor class (the name will be Strings, in this case). This is your default language.

Now, when you want to add, say, German localization, add a localized resx file. This will be typically Strings.de.resx in this case. If you want to add additional localization for, say, Austria, you'll additionally create a Strings.de-AT.resx.

Now go create a string - let's say a string with the name HelloWorld. In your Strings.resx, add this string with the value "Hello, world!". In Strings.de.resx, add "Hallo, Welt!". And in Strings.de-AT.resx, add "Servus, Welt!". That's it so far.

Now you have this generated Strings class, and it has a property with a getter HelloWorld. Getting this property will load "Servus, Welt!" when your locale is de-AT, "Hallo, Welt! when your locale is any other de locale (including de-DE and de-CH), and "Hello, World!" when your locale is anything else. If a string is missing in the localized version, the resource manager will automatically walk up the chain, from the most specialized to the invariant resource.

You can use the ResourceManager class for more control about how exactly you are loading things. The generated Strings class uses it as well.

If width:100% works in any cases, just use that, otherwise you can use vw in this case which is relative to 1% of the width of the viewport.

That means if you want to cover off the width, just use 100vw.

Look at the image I draw for you here:

Try the snippet I created for you as below:

.full-width {_x000D_
  width: 100vw;_x000D_
  height: 100px;_x000D_
  margin-bottom: 40px;_x000D_
  background-color: red;_x000D_
}_x000D_
_x000D_
.one-vw-width {_x000D_
  width: 1vw;_x000D_
  height: 100px;_x000D_
  background-color: red;_x000D_
}

<div class="full-width"></div>_x000D_
<div class="one-vw-width"></div>

These are all great answers, but I needed something a bit more robust, and thought you all might like to have what I created.

It is a simple library method that does dissection and manipulation of URL parameters. The static method has the following sub methods that can be called on the subject URL:

• getHost
• getPath
• getHash
• setHash
• getParams
• getQuery
• setParam
• getParam
• hasParam
• removeParam

Example:

URLParser(url).getParam('myparam1')

var url = "http://www.test.com/folder/mypage.html?myparam1=1&myparam2=2#something";

function URLParser(u){
    var path="",query="",hash="",params;
    if(u.indexOf("#") > 0){
        hash = u.substr(u.indexOf("#") + 1);
        u = u.substr(0 , u.indexOf("#"));
    }
    if(u.indexOf("?") > 0){
        path = u.substr(0 , u.indexOf("?"));
        query = u.substr(u.indexOf("?") + 1);
        params= query.split('&');

The answer is no. Please see Spring Reference: Using @Transactional :

The @Transactional annotation may be placed before an interface definition, a method on an interface, a class definition, or a public method on a class

You can pass multiple arguments to angular filter !

Defining my angular app and and an app level variable -

var app = angular.module('filterApp',[]);
app.value('test_obj', {'TEST' : 'test be check se'});

Your Filter will be like :-

app.filter('testFilter', [ 'test_obj', function(test_obj) {
    function test_filter_function(key, dynamic_data) {
      if(dynamic_data){
        var temp = test_obj[key]; 
        for(var property in dynamic_data){
            temp = temp.replace(property, dynamic_data[property]);
        }
        return temp;
      }
      else{
        return test_obj[key] || key;
      }

    }
    test_filter_function.$stateful = true;
    return test_filter_function;
  }]);

And from HTML you will send data like :-

<span ng-bind="'TEST' | testFilter: { 'be': val, 'se': value2 }"></span>

Here I am sending a JSON object to the filter. You can also send any kind of data like string or number.

also you can pass dynamic number of arguments to filter , in that case you have to use arguments to get those arguments.

For a working demo go here - passing multiple arguments to angular filter

No, TRUNCATE is all or nothing. You can do a DELETE FROM <table> WHERE <conditions> but this loses the speed advantages of TRUNCATE.

Orabig is correct.

You can bind 10.0.2.15 in Ubuntu (VirtualBox) then do a port forwarding from host to guest Ubuntu.

in /etc/redis/redis.conf

bind 10.0.2.15

then, restart redis:

sudo systemctl restart redis

It shall work!

Since you have not replied to my comment above, I am posting a solution for both.

You are missing ' in Extended Properties

For Excel 2003 try this (TRIED AND TESTED)

    private void button1_Click(object sender, EventArgs e)
    {
        String name = "Items";
        String constr = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" +
                        "C:\\Sample.xls" + 
                        ";Extended Properties='Excel 8.0;HDR=YES;';";

        OleDbConnection con = new OleDbConnection(constr);
        OleDbCommand oconn = new OleDbCommand("Select * From [" + name + "$]", con);
        con.Open();

        OleDbDataAdapter sda = new OleDbDataAdapter(oconn);
        DataTable data = new DataTable();
        sda.Fill(data);
        grid_items.DataSource = data;
    }

BTW, I stopped working with Jet longtime ago. I use ACE now.

    private void button1_Click(object sender, EventArgs e)
    {
        String name = "Items";
        String constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" +
                        "C:\\Sample.xls" + 
                        ";Extended Properties='Excel 8.0;HDR=YES;';";

        OleDbConnection con = new OleDbConnection(constr);
        OleDbCommand oconn = new OleDbCommand("Select * From [" + name + "$]", con);
        con.Open();

        OleDbDataAdapter sda = new OleDbDataAdapter(oconn);
        DataTable data = new DataTable();
        sda.Fill(data);
        grid_items.DataSource = data;
    }

For Excel 2007+

    private void button1_Click(object sender, EventArgs e)
    {
        String name = "Items";
        String constr = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" +
                        "C:\\Sample.xlsx" + 
                        ";Extended Properties='Excel 12.0 XML;HDR=YES;';";

        OleDbConnection con = new OleDbConnection(constr);
        OleDbCommand oconn = new OleDbCommand("Select * From [" + name + "$]", con);
        con.Open();

        OleDbDataAdapter sda = new OleDbDataAdapter(oconn);
        DataTable data = new DataTable();
        sda.Fill(data);
        grid_items.DataSource = data;
    }

Well I would atleast clean it up as follows:

print "%.2f kg = %.2f lb = %.2f gal = %.2f l" % (var1, var2, var3, var4)

the small one implement by the OS

<RatingBar
    android:id="@+id/ratingBar"
    style="?android:attr/ratingBarStyleSmall"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" 
    />

You need to set the Content-Disposition header on the HttpResponseMessage:

HttpResponseMessage response = new HttpResponseMessage();
response.StatusCode = HttpStatusCode.OK;
response.Content = new StreamContent(result);
response.Content.Headers.ContentDisposition = new ContentDispositionHeaderValue("attachment")
{
    FileName = "foo.txt"
};

You can auto generate Image map from this website for selected area of image. https://www.image-map.net/

Easiest way to execute!

First of all: I'm the author of the The Single Page Interface Manifesto cited by raganwald

As raganwald has explained very well, the most important aspect of the Single Page Interface (SPI) approach used in FaceBook and Twitter is the use of hash # in URLs

The character ! is added only for Google purposes, this notation is a Google "standard" for crawling web sites intensive on AJAX (in the extreme Single Page Interface web sites). When Google's crawler finds an URL with #! it knows that an alternative conventional URL exists providing the same page "state" but in this case on load time.

In spite of #! combination is very interesting for SEO, is only supported by Google (as far I know), with some JavaScript tricks you can build SPI web sites SEO compatible for any web crawler (Yahoo, Bing...).

The SPI Manifesto and demos do not use Google's format of ! in hashes, this notation could be easily added and SPI crawling could be even easier (UPDATE: now ! notation is used and remains compatible with other search engines).

Take a look to this tutorial, is an example of a simple ItsNat SPI site but you can pick some ideas for other frameworks, this example is SEO compatible for any web crawler.

The hard problem is to generate any (or selected) "AJAX page state" as plain HTML for SEO, in ItsNat is very easy and automatic, the same site is in the same time SPI or page based for SEO (or when JavaScript is disabled for accessibility). With other web frameworks you can ever follow the double site approach, one site is SPI based and another page based for SEO, for instance Twitter uses this "double site" technique.

Yes it should be possible, even if the site is from another domain.

For example, in an HTML page on my site I have an iFrame whose contents are sourced from another website. The iFrame content is a single select field.

I need to be able to read the selected value on my site. In other words, I need to use the select list from another domain inside my own application. I do not have control over any server settings.

Initially therefore we might be tempted to do something like this (simplified):

HTML in my site:

<iframe name='select_frame' src='http://www.othersite.com/select.php?initial_name=jim'></iframe>
<input type='button' name='save' value='SAVE'>

HTML contents of iFrame (loaded from select.php on another domain):

<select id='select_name'>
    <option value='john'>John</option>
    <option value='jim' selected>Jim</option>
</select>

jQuery:

$('input:button[name=save]').click(function() {
    var name = $('iframe[name=select_frame]').contents().find('#select_name').val();
});

However, I receive this javascript error when I attempt to read the value:

Blocked a frame with origin "http://www.myownsite.com" from accessing a frame with origin "http://www.othersite.com". Protocols, domains, and ports must match.

To get around this problem, it seems that you can indirectly source the iFrame from a script in your own site, and have that script read the contents from the other site using a method like file_get_contents() or curl etc.

So, create a script (for example: select_local.php in the current directory) on your own site with contents similar to this:

PHP content of select_local.php:

<?php
    $url = "http://www.othersite.com/select.php?" . $_SERVER['QUERY_STRING'];
    $html_select = file_get_contents($url);
    echo $html_select;
?>

Also modify the HTML to call this local (instead of the remote) script:

<iframe name='select_frame' src='select_local.php?initial_name=jim'></iframe>
<input type='button' name='save' value='SAVE'>

Now your browser should think that it is loading the iFrame content from the same domain.

Here's how I download an ad banner. It's best to do it in the background if you're downloading a large image or a bunch of images.

- (void)viewDidLoad {
    [super viewDidLoad];

    [self performSelectorInBackground:@selector(loadImageIntoMemory) withObject:nil];

}
- (void)loadImageIntoMemory {
    NSString *temp_Image_String = [[NSString alloc] initWithFormat:@"http://yourwebsite.com/MyImageName.jpg"];
    NSURL *url_For_Ad_Image = [[NSURL alloc] initWithString:temp_Image_String];
    NSData *data_For_Ad_Image = [[NSData alloc] initWithContentsOfURL:url_For_Ad_Image];
    UIImage *temp_Ad_Image = [[UIImage alloc] initWithData:data_For_Ad_Image];
    [self saveImage:temp_Ad_Image];
    UIImageView *imageViewForAdImages = [[UIImageView alloc] init];
    imageViewForAdImages.frame = CGRectMake(0, 0, 320, 50);
    imageViewForAdImages.image = [self loadImage];
    [self.view addSubview:imageViewForAdImages];
}
- (void)saveImage: (UIImage*)image {
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString* path = [documentsDirectory stringByAppendingPathComponent: @"MyImageName.jpg" ];
    NSData* data = UIImagePNGRepresentation(image);
    [data writeToFile:path atomically:YES];
}
- (UIImage*)loadImage {
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString* path = [documentsDirectory stringByAppendingPathComponent:@"MyImageName.jpg" ];
    UIImage* image = [UIImage imageWithContentsOfFile:path];
    return image;
}

In case you have multiple images and you want to loop though them and show them 1 by 1 along with titles - this is what you can do. No need to explicitly define ax1, ax2, etc.

1. The catch is you can define dynamic axes(ax) as in Line 1 of code and you can set its title inside a loop.
2. The rows of 2D array is length (len) of axis(ax)
3. Each row has 2 items i.e. It is list within a list (Point No.2)
4. set_title can be used to set title, once the proper axes(ax) or subplot is selected.

import matplotlib.pyplot as plt    
fig, ax = plt.subplots(2, 2, figsize=(6, 8))  
for i in range(len(ax)): 
    for j in range(len(ax[i])):
        ## ax[i,j].imshow(test_images_gr[0].reshape(28,28))
        ax[i,j].set_title('Title-' + str(i) + str(j))

I could do this (demo):

<!doctype html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.0/jquery.min.js"></script>
</head>
<body>
    <form >
        <input type="file" id="f" data-max-size="32154" />
        <input type="submit" />
    </form>
<script>
$(function(){
    $('form').submit(function(){
        var isOk = true;
        $('input[type=file][data-max-size]').each(function(){
            if(typeof this.files[0] !== 'undefined'){
                var maxSize = parseInt($(this).attr('max-size'),10),
                size = this.files[0].size;
                isOk = maxSize > size;
                return isOk;
            }
        });
        return isOk;
    });
});
</script>
</body>
</html>

It turns out that Popper.js doesn't provide compiled files on its GitHub repository. Therefore, one has to compile the project on his/her own or download compiled files from CDNs. It cannot be automatically imported.

Writing as

var formData = new FormData;
var array = ['1', '2'];
for (var i = 0; i < array.length; i++) {
    formData.append('array_php_side[]', array[i]);
}

you can receive just as normal array post/get by php.

The problem is the tv.setText(text). The variable tv is probably null and you call the setText method on that null, which you can't. My guess that the problem is on the findViewById method, but it's not here, so I can't tell more, without the code.

just remove the breaks between li's in your html code... make the li's in one line only..

0 in the start here specifies that the base is 8 (not 10), which is pretty easy to see:

>>> int('010101', 0)
4161

If you don't start with a 0, then python assumes the number is base 10.

>>> int('10101', 0)
10101

You don't mention if this is an anonymous PL/SQL block or a declarative one ie. Package, Procedure or Function. However, in PL/SQL a COMMIT must be explicitly made to save your transaction(s) to the database. The COMMIT actually saves all unsaved transactions to the database from your current user's session.

If an error occurs the transaction implicitly does a ROLLBACK.

This is the default behaviour for PL/SQL.

Another reason to prefer NSOperation over GCD is the cancelation mechanism of NSOperation. For example, an App like 500px that shows dozens of photos, use NSOperation we can cancel requests of invisible image cells when we scroll table view or collection view, this can greatly improve App performance and reduce memory footprint. GCD can't easily support this.

Also with NSOperation, KVO can be possible.

Here is an article from Eschaton which is worth reading.

Yes by using spring-boot with hibernate configuration files we can persist the data to the database. keep hibernating .cfg.xml in your src/main/resources folder for reading the configurations related to database.

When requesting paginated data, you know (by explicit page size parameter value or default page size value) the page size, so you know if you got all data in response or not. When there is less data in response than is a page size, then you got whole data. When a full page is returned, you have to ask again for another page.

I prefer have separate endpoint for count (or same endpoint with parameter countOnly). Because you could prepare end user for long/time consuming process by showing properly initiated progressbar.

If you want to return datasize in each response, there should be pageSize, offset mentionded as well. To be honest the best way is to repeat a request filters too. But the response became very complex. So, I prefer dedicated endpoint to return count.

<data>
  <originalRequest>
    <filter/>
    <filter/>
  </originalReqeust>
  <totalRecordCount/>
  <pageSize/>
  <offset/>
  <list>
     <item/>
     <item/>
  </list>
</data>

Couleage of mine, prefer a countOnly parameter to existing endpoint. So, when specified the response contains metadata only.

endpoint?filter=value

<data>
  <count/>
  <list>
    <item/>
    ...
  </list>
</data>

endpoint?filter=value&countOnly=true

<data>
  <count/>
  <!-- empty list -->
  <list/>
</data>

add path(:/usr/local/bin/) in profile.

It was particular for me. I am sending a header named 'SESSIONHASH'. No problem for Chrome and Opera, but Firefox also wants this header in the list "Access-Control-Allow-Headers". Otherwise, Firefox will throw the CORS error.

I got this

String appPath = App.getApp().getApplicationContext().getFilesDir().getAbsolutePath();

from here:

Something like this for $.ajax (HTML5 only though):

$.ajax({
    xhr: function() {
        var xhr = new window.XMLHttpRequest();
        xhr.upload.addEventListener("progress", function(evt) {
            if (evt.lengthComputable) {
                var percentComplete = evt.loaded / evt.total;
                //Do something with upload progress here
            }
       }, false);

       xhr.addEventListener("progress", function(evt) {
           if (evt.lengthComputable) {
               var percentComplete = evt.loaded / evt.total;
               //Do something with download progress
           }
       }, false);

       return xhr;
    },
    type: 'POST',
    url: "/",
    data: {},
    success: function(data){
        //Do something on success
    }
});

Found out by adding this to your url parameters

approval_prompt=force

Update:

Use access_type=offline&prompt=consent instead.

approval_prompt=force no longer works https://github.com/googleapis/oauth2client/issues/453

Using Java 8 or above you can use an Optional and Java Streams.

So you can simply use the JdbcTemplate.queryForList() method, create a Stream and use Stream.findFirst() which will return the first value of the Stream or an empty Optional:

public Optional<String> test() {
    String sql = "select ID_NMB_SRZ from codb_owner.TR_LTM_SLS_RTN where id_str_rt = '999' and ID_NMB_SRZ = '60230009999999'";
    return jdbc.queryForList(sql, String.class)
            .stream().findFirst();
}

To improve the performance of the query you can append LIMIT 1 to your query, so not more than 1 item is transferred from the database.

Yes, gzip will let you do this. If you simply run gzip > foo.gz, it will compress STDIN to the file foo.gz. You can also pipe data into it, like some_command | gzip > foo.gz.

In case you want to increase the font of the labels of the histogram when setting labels=TRUE

bp=hist(values, labels = FALSE, 
 main='Histogram',
 xlab='xlab',ylab='ylab',  cex.main=2, cex.lab=2,cex.axis=2)

text(x=bp$mids, y=bp$counts, labels=bp$counts ,cex=2,pos=3)

Try This:

foreach (string files in Directory.GetFiles(SourcePath))
{
   FileInfo fileInfo = new FileInfo(files);
   fileInfo.Delete(); //delete the files first. 
}
Directory.Delete(SourcePath);// delete the directory as it is empty now.

The best solution I could find at present time to open a window maximized is (Internet Explorer 11, Chrome 49, Firefox 45):

  var popup = window.open("your_url", "popup", "fullscreen");
  if (popup.outerWidth < screen.availWidth || popup.outerHeight < screen.availHeight)
  {
    popup.moveTo(0,0);
    popup.resizeTo(screen.availWidth, screen.availHeight);
  }

see https://jsfiddle.net/8xwocrp6/7/

Note 1: It does not work on Edge (13.1058686). Not sure whether it's a bug or if it's as designed (I've filled a bug report, we'll see what they have to say about it). Here is a workaround:

if (navigator.userAgent.match(/Edge\/\d+/g))
{
    return window.open("your_url", "popup", "width=" + screen.width + ",height=" + screen.height);
}

Note 2: moveTo or resizeTo will not work (Access denied) if the window you are opening is on another domain.

Maybe it's is completely possible with only CSS but I prefer to avoid "float" as much as I can because it interferes with it's parent's height.

If you are using jQuery, you can create a simple `wrapN` plugin that is similar to `wrapAll` except it only wraps "N" elements and then breaks and wraps the next "N" elements using a loop. Then set your wrappers class to `display: block;`.

(function ($) {
    $.fn.wrapN = function (wrapper, n, start) {
        if (wrapper === undefined || n === undefined) return false;
        if (start === undefined) start = 0;
        for (var i = start; i < $(this).size(); i += n)
           $(this).slice(i, i + n).wrapAll(wrapper);
        return this;
    };
}(jQuery));

$(document).ready(function () {
    $("li").wrapN("<span class='break' />", 3);
});

Here is a JSFiddle of the finished product:

http://jsfiddle.net/dustinpoissant/L79ahLoz/

The full modern solution to your problem is purely CSS-based, but note that older browsers won't support it, in which cases you'd need to fallback to solutions such as the others have provided.

So in pure CSS:

-webkit-user-select: none;
-khtml-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
-o-user-select: none;
user-select: none;

However the mouse cursor will still change to a caret when over the element's text, so you add to that:

cursor: default;

Modern CSS is pretty elegant.

If you use sizeof()then a char *str and char str[] will return different answers. char str[] will return the length of the string(including the string terminator) while char *str will return the size of the pointer(differs as per compiler).

after trying for ours! chrome understands that I want the child element to be 100% height when I set the display value to inline block. btw setting float will causing it.

display:inline-block

update

this is not working. the solution is to get the parentnode offsetheight and use it at the and of the page with javascript.

<script>
    SomedivElement = document.getElementById('mydiv');
    SomedivElement.style.height = String(nvleft.parentNode.offsetHeight) + 'px';    
</script>

If you are developing a Chrome App / Extension use the chrome.i18n API.

chrome.i18n.getAcceptLanguages(function(languages) {
  console.log(languages);
  // ["en-AU", "en", "en-US"]
});

There is another near perfect solution, taken from another SO answer:

if( (1 < history.length) && document.referrer ) {
    history.back();
}
else {
    // If you can't go back in history, you could perhaps close the window ?
    window.close();
}

Someone reported that it does not work when using target="_blank" but it seems to work for me on Chrome.

The reason for this error is very simple. Your AJAX is trying to call over HTTP whereas your server is running over HTTPS, so your server is denying calling your AJAX. This can be fixed by adding the following line inside the head tag of your main HTML file:

<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests"> 

It depends on what you want to do.

Case # 1: Save the model to use it yourself for inference: You save the model, you restore it, and then you change the model to evaluation mode. This is done because you usually have BatchNorm and Dropout layers that by default are in train mode on construction:

torch.save(model.state_dict(), filepath)

#Later to restore:
model.load_state_dict(torch.load(filepath))
model.eval()

Case # 2: Save model to resume training later: If you need to keep training the model that you are about to save, you need to save more than just the model. You also need to save the state of the optimizer, epochs, score, etc. You would do it like this:

state = {
    'epoch': epoch,
    'state_dict': model.state_dict(),
    'optimizer': optimizer.state_dict(),
    ...
}
torch.save(state, filepath)

To resume training you would do things like: state = torch.load(filepath), and then, to restore the state of each individual object, something like this:

model.load_state_dict(state['state_dict'])
optimizer.load_state_dict(state['optimizer'])

Since you are resuming training, DO NOT call model.eval() once you restore the states when loading.

Case # 3: Model to be used by someone else with no access to your code: In Tensorflow you can create a .pb file that defines both the architecture and the weights of the model. This is very handy, specially when using Tensorflow serve. The equivalent way to do this in Pytorch would be:

torch.save(model, filepath)

# Then later:
model = torch.load(filepath)

This way is still not bullet proof and since pytorch is still undergoing a lot of changes, I wouldn't recommend it.

As already mentioned that, break-statement works only with switches and loops. Here is another way to achieve what is being asked. I am reproducing https://stackoverflow.com/a/257421/1188057 as nobody else mentioned it. It's just a trick involving the do-while loop.

do {
  // do something
  if (error) {
    break;
  }
  // do something else
  if (error) {
    break;
  }
  // etc..
} while (0);

Though I would prefer the use of goto-statement.

It failed because you used ajax="false". This fires a full synchronous request which in turn causes a full page reload, causing the oncomplete to be never fired (note that all other ajax-related attributes like process, onstart, onsuccess, onerror and update are also never fired).

That it worked when you removed actionListener is also impossible. It should have failed the same way. Perhaps you also removed ajax="false" along it without actually understanding what you were doing. Removing ajax="false" should indeed achieve the desired requirement.

Also is it possible to execute actionlistener and oncomplete simultaneously?

No. The script can only be fired before or after the action listener. You can use onclick to fire the script at the moment of the click. You can use onstart to fire the script at the moment the ajax request is about to be sent. But they will never exactly simultaneously be fired. The sequence is as follows:

• User clicks button in client
• onclick JavaScript code is executed
• JavaScript prepares ajax request based on process and current HTML DOM tree
• onstart JavaScript code is executed
• JavaScript sends ajax request from client to server
• JSF retrieves ajax request
• JSF processes the request lifecycle on JSF component tree based on process
• actionListener JSF backing bean method is executed
• action JSF backing bean method is executed
• JSF prepares ajax response based on update and current JSF component tree
• JSF sends ajax response from server to client
• JavaScript retrieves ajax response
  • if HTTP response status is 200, onsuccess JavaScript code is executed
  • else if HTTP response status is 500, onerror JavaScript code is executed
• JavaScript performs update based on ajax response and current HTML DOM tree
• oncomplete JavaScript code is executed

Note that the update is performed after actionListener, so if you were using onclick or onstart to show the dialog, then it may still show old content instead of updated content, which is poor for user experience. You'd then better use oncomplete instead to show the dialog. Also note that you'd better use action instead of actionListener when you intend to execute a business action.

That should cover it.

If you only want to install the latest official JRE from Oracle, you can get it there, install it, and export the new JAVA_HOME in the terminal.

• Open your Terminal
• java -version gives you an error and a popup
• Get the JRE dmg on http://www.oracle.com/technetwork/java/javase/downloads/index.html
• Install it
• In your terminal, type: export JAVA_HOME="/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home"
• java -version now gives you java version "1.7.0_45"

That's the cleanest way I found to install the latest JRE.

You can add the export JAVA_HOME line in your .bashrc to have java permanently in your Terminal:

echo export JAVA_HOME=\"/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home\" >> ~/.bashrc

Maybe you can use this properties:

ActiveCell.Interior.ColorIndex - one of 56 preset colors

and

ActiveCell.Interior.Color - RGB color, used like that:

ActiveCell.Interior.Color = RGB(255,255,255)

you might use

a.view(1,5)

"End Process" on the Processes-Tab calls TerminateProcess which is the most ultimate way Windows knows to kill a process.

If it doesn't go away, it's currently locked waiting on some kernel resource (probably a buggy driver) and there is nothing (short of a reboot) you could do to make the process go away.

Have a look at this blog-entry from wayback when: http://blogs.technet.com/markrussinovich/archive/2005/08/17/unkillable-processes.aspx

Unix based systems like Linux also have that problem where processes could survive a kill -9 if they are in what's known as "Uninterruptible sleep" (shown by top and ps as state D) at which point the processes sleep so well that they can't process incoming signals (which is what kill does - sending signals).

Normally, Uninterruptible sleep should not last long, but as under Windows, broken drivers or broken userpace programs (vfork without exec) can end up sleeping in D forever.

In Chrome is keys(foo.prototype). Returns ["a", "b"].

See: https://developer.chrome.com/devtools/docs/commandline-api#keysobject

Later edit: If you need to copy it quick (for bigger objects), do copy(keys(foo.prototype)) and you will have it in the clipboard.

All of the above answers are correct and recommended; this answer is intended only as a last-resort if none of the aforementioned approaches can be used.

If all else fails, you can always recompile your program with various temporary debug-print statements (e.g. fprintf(stderr, "CHECKPOINT REACHED @ %s:%i\n", __FILE__, __LINE__);) sprinkled throughout what you believe to be the relevant parts of your code. Then run the program, and observe what the was last debug-print printed just before the crash occurred -- you know your program got that far, so the crash must have happened after that point. Add or remove debug-prints, recompile, and run the test again, until you have narrowed it down to a single line of code. At that point you can fix the bug and remove all of the temporary debug-prints.

It's quite tedious, but it has the advantage of working just about anywhere -- the only times it might not is if you don't have access to stdout or stderr for some reason, or if the bug you are trying to fix is a race-condition whose behavior changes when the timing of the program changes (since the debug-prints will slow down the program and change its timing)

For red lines an points

plt.plot(dates, values, '.r-') 

or for x markers and blue lines

There are few modes to open file (read, write etc..)

If you want to read from file you should type file = open("File.txt","r"), if write than file = open("File.txt","w"). You need to give the right permission regarding your usage.

more modes:

• r. Opens a file for reading only.
• rb. Opens a file for reading only in binary format.
• r+ Opens a file for both reading and writing.
• rb+ Opens a file for both reading and writing in binary format.
• w. Opens a file for writing only.
• you can find more modes in here

Suppose we have directory structure like

1]

/home/User/P/Q/R

We want to access the path of "P" from the directory R then we can access using

ROOT = os.path.abspath(os.path.join("..", os.pardir));

2]

/home/User/P/Q/R

We want to access the path of "Q" directory from the directory R then we can access using

ROOT = os.path.abspath(os.path.join(".", os.pardir));

RadioButton by default takes the colour of colorAccent in res/values/colors.xml file. So go to that file and change the value of

<color name="colorAccent">#3F51B5</color>

to the colour you want.

why don't you store your values in HTML5 storage objects such as sessionStorage or localStorage, visit HTML5 Storage Doc to get more details. Using this you can store intermediate values temporarily/permanently locally and then access your values later.

To store values for a session:

sessionStorage.getItem('label')
sessionStorage.setItem('label', 'value')

or more permanently:

localStorage.getItem('label')
localStorage.setItem('label', 'value')

So you can store (temporarily) form data between multiple pages using HTML5 storage objects which you can even retain after reload..

Since PHP 5.5, you can use array_column:

$ids = array_column($users, 'id');

This is the preferred option on any modern project. However, if you must support PHP<5.5, the following alternatives exist:

Since PHP 5.3, you can use array_map with an anonymous function, like this:

$ids = array_map(function ($ar) {return $ar['id'];}, $users);

Before ^{_{(Technically PHP 4.0.6+)}}, you must create an anonymous function with create_function instead:

$ids = array_map(create_function('$ar', 'return $ar["id"];'), $users);

It's a way of adding text to HTML without it being rendered or normalized.

It's no different than adding it like:

 <textarea style="display:none"><span>{{name}}</span></textarea>

For Spark 1.5 or later, you can use the functions package:

from pyspark.sql.functions import *
newDf = df.withColumn('address', regexp_replace('address', 'lane', 'ln'))

Quick explanation:

• The function withColumn is called to add (or replace, if the name exists) a column to the data frame.
• The function regexp_replace will generate a new column by replacing all substrings that match the pattern.

You can use that, I create a simple extension for Dictionary in github https://github.com/DaRkD0G/LoadExtension

extension Dictionary {
    /**
        Load a Plist file from the app bundle into a new dictionary

        :param: File name
        :return: Dictionary<String, AnyObject>?
    */
    static func loadPlistFromProject(filename: String) -> Dictionary<String, AnyObject>? {

        if let path = NSBundle.mainBundle().pathForResource("GameParam", ofType: "plist") {
            return NSDictionary(contentsOfFile: path) as? Dictionary<String, AnyObject>
        }
        println("Could not find file: \(filename)")
        return nil
    }
}

And you can use that for load

/**
  Example function for load Files Plist

  :param: Name File Plist
*/
func loadPlist(filename: String) -> ExampleClass? {
    if let dictionary = Dictionary<String, AnyObject>.loadPlistFromProject(filename) {
        let stringValue = (dictionary["name"] as NSString)
        let intergerValue = (dictionary["score"] as NSString).integerValue
        let doubleValue = (dictionary["transition"] as NSString).doubleValue

        return ExampleClass(stringValue: stringValue, intergerValue: intergerValue, doubleValue: doubleValue)
    }
    return nil
}

#include <stdio.h>

using namespace std;

int main()

    float arr[2095879];
    long k,i;
    char ch[100];
    k=0;

    do{
        cin>>ch;
        arr[k]=atof(ch);
        k++;
     }while(ch[0]=='0');

    cout<<"Array output"<<endl;
    for(i=0;i<k;i++){
        cout<<arr[i]<<endl;
    }

    return 0;
}

The above code works, the maximum float or int array size that could be defined was with size 2095879, and exit condition would be non zero beginning input number

os.system() returns the (encoded) process exit value. 0 means success:

On Unix, the return value is the exit status of the process encoded in the format specified for wait(). Note that POSIX does not specify the meaning of the return value of the C system() function, so the return value of the Python function is system-dependent.

The output you see is written to stdout, so your console or terminal, and not returned to the Python caller.

If you wanted to capture stdout, use subprocess.check_output() instead:

x = subprocess.check_output(['whoami'])

.md is markdown. README.md is used to generate the html summary you see at the bottom of projects. Github has their own flavor of Markdown.

Order of Preference: If you have two files named README and README.md, the file named README.md is preferred, and it will be used to generate github's html summary.

FWIW, Stack Overflow uses local Markdown modifications as well (also see Stack Overflow's C# Markdown Processor)

    }

The appropriate way for doing this:

        if 'download' in request.form:
            pass # do something
        elif 'watch' in request.form:
            pass # do something else

Put watch and download buttons into your template:

<input type="submit" name="download" value="Download">
<input type="submit" name="watch" value="Watch">

You have 4 columns A,B,C,D

Here is a better way to select the columns you need for the new dataframe:-

df2 = df1[['A','D']]

if you wish to use column numbers instead, use:-

df2 = df1[[0,3]]

sudo apt-get install zlib1g:i386 fixed the Gradle issue on Android 2.1.1 on Xubuntu 16.04.

First of all print isn't a function in Python 2, it is a statement.

To suppress the automatic newline add a trailing ,(comma). Now a space will be used instead of a newline.

Demo:

print 1,
print 2

output:

1 2

Or use Python 3's print() function:

from __future__ import print_function
print(1, end=' ') # default value of `end` is '\n'
print(2)

As you can clearly see print() function is much more powerful as we can specify any string to be used as end rather a fixed space.

A serval times of fighting, I finally solved the problem.
(Note: I use standard AES as symmetric algorithm. This answer may not suitable for everyone.)

1. Change the algorithm class. Replace the RijndaelManaged class to AESManaged one.
2. Do not explicit set the KeySize of algorithm class, left them default.
   (This is the very important step. I think there is a bug in KeySize property.)

Here is a list you want to check which argument you might have missed:

• Key
  (byte array, length must be exactly one of 16, 24, 32 byte for different key size.)
• IV
  (byte array, 16 bytes)
• CipherMode
  (One of CBC, CFB, CTS, ECB, OFB)
• PaddingMode
  (One of ANSIX923, ISO10126, None, PKCS7, Zeros)

Even better approach using array's join method

I was comparing worldcitiesdatabae.info with www.worldcitiesdatabase.com and it appears the latter one to be more resourceful. However, maxmind has a free database so then why buy a cities database. Just get the free one and there is lot of help available on internet about maxmind db. If you put in extra efforts then you can save those few bucks :)

There is one interesting option in this scenario I haven`t found in answers here.

You can Nack messages with "requeue" feature in one consumer to process them in another. Generally speaking it is not a right way, but maybe it will be good enough for someone.

https://www.rabbitmq.com/nack.html

And beware of loops (when all concumers nack+requeue message)!

In my case, I had to select the "src/main/java" and select the "Run As" menu Just like this, so that "Spring Boot App" would be displayed as here.

All the solutions here failed to work on my VS2013, however I put the #define _CRT_SECURE_NO_WARNINGS in the stdafx.h just before the #pragma once and all warnings were suppressed. Note: I only code for prototyping purposes to support my research so please make sure you understand the implications of this method when writing your code.

Hope this helps

Here is an improvement on miku's original answer that addresses Dennis Williamson's concerns about the case where the variable is not set:

the_world_is_flat=true

if ${the_world_is_flat:-false} ; then
    echo "Be careful not to fall off!"
fi

And to test if the variable is false:

if ! ${the_world_is_flat:-false} ; then
    echo "Be careful not to fall off!"
fi

About other cases with a nasty content in the variable, this is a problem with any external input fed to a program.

Any external input must be validated before trusting it. But that validation has to be done just once, when that input is received.

It doesn't have to impact the performance of the program by doing it on every use of the variable like Dennis Williamson suggests.

You probably don't included the path to mysql headers, which can be found at /usr/include/mysql, on several unix systems I think. See this post, it may be helpfull.

By the way, related with the question of that guy above, about syntastic configuration. One can add the following to your ~/.vimrc:

let b:syntastic_c_cflags = '-I/usr/include/mysql'

and you can always check the wiki page of the developers on github. Enjoy!

I just looked and found cell|all output|clear which worked with:

Could you use jQuery, since it's cross-browser compatible?

function isOnScreen(element)
{
    var curPos = element.offset();
    var curTop = curPos.top;
    var screenHeight = $(window).height();
    return (curTop > screenHeight) ? false : true;
}

And then call the function using something like:

if(isOnScreen($('#myDivId'))) { /* Code here... */ };

var confirm=document.getElementById("confirm").value;
         if((confirm.checked==false)
         {

There is a wonderful print_r implementation for JavaScript in php.js library.

Note, you should also add echo support in the code.

Here is how I did this, somewhat similar to the solutions above. Just make sure you call the loadDots() method after all images are downloaded.

    private int dotsCount;
    private TextView dotsTextView[];

    private void setupAdapter() {
        adapter = new SomeAdapter(getContext(), images);
        viewPager.setAdapter(adapter);
        viewPager.setCurrentItem(0);
        viewPager.addOnPageChangeListener(viewPagerPageChangeListener);
    }

    private final ViewPager.OnPageChangeListener viewPagerPageChangeListener = new ViewPager.OnPageChangeListener() {
        @Override
        public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {}

        @Override
        public void onPageSelected(int position) {
            for (int i = 0; i < dotsCount; i++)
                dotsTextView[i].setTextColor(Color.GRAY);

            dotsTextView[position].setTextColor(Color.WHITE);
        }

        @Override
        public void onPageScrollStateChanged(int state) {}
    };

    protected void loadDots() {
        dotsCount = adapter.getCount();
        dotsTextView = new TextView[dotsCount];
        for (int i = 0; i < dotsCount; i++) {
            dotsTextView[i] = new TextView(getContext());
            dotsTextView[i].setText(R.string.dot);
            dotsTextView[i].setTextSize(45);
            dotsTextView[i].setTypeface(null, Typeface.BOLD);
            dotsTextView[i].setTextColor(android.graphics.Color.GRAY);
            mDotsLayout.addView(dotsTextView[i]);
        }
        dotsTextView[0].setTextColor(Color.WHITE);
    }

MSVC 2015 Update 1, cl.exe version 19.00.24215.1:

#include <iostream>

template<typename X, typename Y>
struct A

  template<typename Z>
  static void f()
  {
    std::cout << "from A::f():" << std::endl
      << __FUNCTION__ << std::endl
      << __func__ << std::endl
      << __FUNCSIG__ << std::endl;
  }
};

void main()

  std::cout << "from main():" << std::endl
    << __FUNCTION__ << std::endl
    << __func__ << std::endl
    << __FUNCSIG__ << std::endl << std::endl;

  A<int, float>::f<bool>();
}

output:

from main():

main
int __cdecl main(void)

from A::f():
A<int,float>::f
f

Using of __PRETTY_FUNCTION__ triggers undeclared identifier error, as expected.

What about:

int a_as_int = (int)'a';

I too faced the same problem in Angular 6. I solved the issue by using below code. Add the code in component.ts file.

import { HttpHeaders } from '@angular/common/http';

headers;

constructor() {
    this.headers = new HttpHeaders();
    this.headers.append('Access-Control-Allow-Headers', 'Authorization');
}

getData() {
    this.http.get(url,this.headers). subscribe (res => {
    // your code here...
})}

A quick addition to Duncan C's original description vis-á-vie IB behavior. He writes: "It's trivial to make hyperlinks clickable in a UITextView. You just set the "detect links" checkbox on the view in IB, and it detects http links and turns them into hyperlinks."

My experience (at least in xcode 7) is that you also have to unclick the "Editable" behavior for the urls to be detected & clickable.

static T DeserializeXml<T>(string sourceXML) where T : class
{
    var serializer = new XmlSerializer(typeof(T));
    T result = null;

    using (TextReader reader = new StringReader(sourceXML))
    {
        result = (T) serializer.Deserialize(reader);
    }

    return result;
}

In C you get an implicit conversion from void * to any other (data) pointer.

Just like with nextSibling and nextElementSibling, just remember that, properties with "element" in their name always returns Element or null. Properties without can return any other kind of node.

console.log(document.body.parentNode, "is body's parent node");    // returns <html>
console.log(document.body.parentElement, "is body's parent element"); // returns <html>

var html = document.body.parentElement;
console.log(html.parentNode, "is html's parent node"); // returns document
console.log(html.parentElement, "is html's parent element"); // returns null

-->Get all keys from redis-cli

-redis 127.0.0.1:6379> keys *

-->Get list of patterns

-redis 127.0.0.1:6379> keys d??

This will produce keys which start by 'd' with three characters.

-redis 127.0.0.1:6379> keys *t*

This wil get keys with matches 't' character in key

-->Count keys from command line by

-redis-cli keys * |wc -l

You should install the intel hardware acceleration first on sdk manager than you can start to create your virtual device on AVD manager

I use this query

SELECT id FROM table_name WHERE field_name REGEXP '"key_name":"([^"])key_word([^"])"';
or
SELECT id FROM table_name WHERE field_name RLIKE '"key_name":"[[:<:]]key_word[[:>:]]"';

The first query I use it to search partial value. The second query I use it to search exact word.

This can de done in a relatively elegant way using SELECT DISTINCT, as follows:

SELECT DISTINCT ON (sensorID)
sensorID, timestamp, sensorField1, sensorField2 
FROM sensorTable
ORDER BY sensorID, timestamp DESC;

The above works for PostgreSQL (some more info here) but I think also other engines. In case it's not obvious, what this does is sort the table by sensor ID and timestamp (newest to oldest), and then returns the first row (i.e. latest timestamp) for each unique sensor ID.

In my use case I have ~10M readings from ~1K sensors, so trying to join the table with itself on a timestamp-based filter is very resource-intensive; the above takes a couple of seconds.

Update:

As @Ryan Leonard pointed out correctly, my answer doesn't really fix the point I made my self... You need to both trim and remove double spaces with (for example) string.replace(/ +/g, " ").. Or you could split the el.className and then remove empty values with (for example) arr.filter(Boolean).

const classes = element.className.split(' ').filter(Boolean);

or more modern

const classes = element.classList;

Old:

With all the given answers, you should never forget to user .trim() (or $.trim())

Because classes gets added and removed, it can happen that there are multiple spaces between class string.. e.g. 'class1 class2       class3'..

This would turn into ['class1', 'class2','','','', 'class3']..

When you use trim, all multiple spaces get removed..

If you only have Y to send :

$> yes Y |./your_script

If you only have N to send :

$> yes N |./your_script

This CSS seems to work in Safari and Chrome:

div#div2
{
-webkit-transform:rotate(90deg); /* Chrome, Safari, Opera */
transform:rotate(90deg); /* Standard syntax */
}

and in the body:

<div id="div2"><img src="image.jpg"  ></div>

But this (and the .rotate90 example above) pushes the rotated image higher up on the page than if it were un-rotated. Not sure how to control placement of the image relative to text or other rotated images.

Running queries on hot-standby server is somewhat tricky — it can fail, because during querying some needed rows might be updated or deleted on primary. As a primary does not know that a query is started on secondary it thinks it can clean up (vacuum) old versions of its rows. Then secondary has to replay this cleanup, and has to forcibly cancel all queries which can use these rows.

Longer queries will be canceled more often.

You can work around this by starting a repeatable read transaction on primary which does a dummy query and then sits idle while a real query is run on secondary. Its presence will prevent vacuuming of old row versions on primary.

More on this subject and other workarounds are explained in Hot Standby — Handling Query Conflicts section in documentation.

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

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

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

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

springBoot {
    executable = true
}

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

init.d example:

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

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

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

Or use a systemd script:

[Unit]
Description=yourapp
After=syslog.target

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

[Install]
WantedBy=multi-user.target

More information at the following links:

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

1. Use ref attribute on DOM element for reference

<div class="content scrollable" ref="msgContainer">
    <!-- content -->
</div>

2. You need to setup a WATCH

  data() {
    return {
      count: 5
    };
  },
  watch: {
    count: function() {
      this.$nextTick(function() {
        var container = this.$refs.msgContainer;
        container.scrollTop = container.scrollHeight + 120;
      });
    }
  }

3. Ensure you're using proper CSS

.scrollable {
  overflow: hidden;
  overflow-y: scroll;
  height: calc(100vh - 20px);
}

Actually, You can achieve this with current typescript:

type Grow<T, A extends Array<T>> = ((x: T, ...xs: A) => void) extends ((...a: infer X) => void) ? X : never;
type GrowToSize<T, A extends Array<T>, N extends number> = { 0: A, 1: GrowToSize<T, Grow<T, A>, N> }[A['length'] extends N ? 0 : 1];

export type FixedArray<T, N extends number> = GrowToSize<T, [], N>;

Examples:

// OK
const fixedArr3: FixedArray<string, 3> = ['a', 'b', 'c'];

// Error:
// Type '[string, string, string]' is not assignable to type '[string, string]'.
//   Types of property 'length' are incompatible.
//     Type '3' is not assignable to type '2'.ts(2322)
const fixedArr2: FixedArray<string, 2> = ['a', 'b', 'c'];

// Error:
// Property '3' is missing in type '[string, string, string]' but required in type 
// '[string, string, string, string]'.ts(2741)
const fixedArr4: FixedArray<string, 4> = ['a', 'b', 'c'];

EDIT (after a long time)

This should handle bigger sizes (as basically it grows array exponentially until we get to closest power of two):

type Shift<A extends Array<any>> = ((...args: A) => void) extends ((...args: [A[0], ...infer R]) => void) ? R : never;

type GrowExpRev<A extends Array<any>, N extends number, P extends Array<Array<any>>> = A['length'] extends N ? A : {
  0: GrowExpRev<[...A, ...P[0]], N, P>,
  1: GrowExpRev<A, N, Shift<P>>
}[[...A, ...P[0]][N] extends undefined ? 0 : 1];

type GrowExp<A extends Array<any>, N extends number, P extends Array<Array<any>>> = A['length'] extends N ? A : {
  0: GrowExp<[...A, ...A], N, [A, ...P]>,
  1: GrowExpRev<A, N, P>
}[[...A, ...A][N] extends undefined ? 0 : 1];

export type FixedSizeArray<T, N extends number> = N extends 0 ? [] : N extends 1 ? [T] : GrowExp<[T, T], N, [[T]]>;

You need to make TestGetMethod async too and attach await in front of GetIdList(); will unwrap the task to List<int>, So if your helper function is returning Task make sure you have await as you are calling the function async too.

public Task<List<int>> TestGetMethod()
{
    return GetIdList();
}    

async Task<List<int>> GetIdList()
{
    using (HttpClient proxy = new HttpClient())
    {
        string response = await proxy.GetStringAsync("www.test.com");
        List<int> idList = JsonConvert.DeserializeObject<List<int>>();
        return idList;
    }
}

Another option

public async void TestGetMethod(List<int> results)
{
    results = await GetIdList(); // await will unwrap the List<int>
}

The best way to use is white-space: nowrap; This will align the text to one line.

With Google Guava's Ints class, your method can be changed to:

public static int safeLongToInt(long l) {
    return Ints.checkedCast(l);
}

From the linked docs:

checkedCast

public static int checkedCast(long value)

Returns the int value that is equal to value, if possible.

Parameters: value - any value in the range of the int type

Returns: the int value that equals value

Throws: IllegalArgumentException - if value is greater than Integer.MAX_VALUE or less than Integer.MIN_VALUE

Incidentally, you don't need the safeLongToInt wrapper, unless you want to leave it in place for changing out the functionality without extensive refactoring of course.

I had a similar problem. My laptop ran out of battery during a git operation. Boo.

I didn't have any backups. (N.B. Ubuntu One is not a backup solution for git; it will helpfully overwrite your sane repository with your corrupted one.)

To the git wizards, if this was a bad way to fix it, please leave a comment. It did, however, work for me... at least temporarily.

Step 1: Make a backup of .git (in fact I do this in between every step that changes something, but with a new copy-to name, e.g. .git-old-1, .git-old-2, etc.):

cp -a .git .git-old

Step 2: Run git fsck --full

nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git fsck --full
error: object file .git/objects/8b/61d0135d3195966b443f6c73fb68466264c68e is empty
fatal: loose object 8b61d0135d3195966b443f6c73fb68466264c68e (stored in .git/objects/8b/61d0135d3195966b443f6c73fb68466264c68e) is corrupt

Step 3: Remove the empty file. I figured what the heck; its blank anyway.

nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ rm .git/objects/8b/61d0135d3195966b443f6c73fb68466264c68e 
rm: remove write-protected regular empty file `.git/objects/8b/61d0135d3195966b443f6c73fb68466264c68e'? y

Step 3: Run git fsck again. Continue deleting the empty files. You can also cd into the .git directory and run find . -type f -empty -delete -print to remove all empty files. Eventually git started telling me it was actually doing something with the object directories:

nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git fsck --full
Checking object directories: 100% (256/256), done.
error: object file .git/objects/e0/cbccee33aea970f4887194047141f79a363636 is empty
fatal: loose object e0cbccee33aea970f4887194047141f79a363636 (stored in .git/objects/e0/cbccee33aea970f4887194047141f79a363636) is corrupt

Step 4: After deleting all of the empty files, I eventually came to git fsck actually running:

nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git fsck --full
Checking object directories: 100% (256/256), done.

Step 5: Try git reflog. Fail because my HEAD is broken.

nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git reflog
fatal: bad object HEAD

Step 6: Google. Find this. Manually get the last two lines of the reflog:

nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ tail -n 2 .git/logs/refs/heads/master
f2d4c4868ec7719317a8fce9dc18c4f2e00ede04 9f0abf890b113a287e10d56b66dbab66adc1662d Nathan VanHoudnos <[email protected]> 1347306977 -0400  commit: up to p. 24, including correcting spelling of my name
9f0abf890b113a287e10d56b66dbab66adc1662d af9fc0c5939eee40f6be2ed66381d74ec2be895f Nathan VanHoudnos <[email protected]> 1347358589 -0400  commit: fixed up to page 28

Step 7: Note that from Step 6 we learned that the HEAD is currently pointing to the very last commit. So let's try to just look at the parent commit:

nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git show 9f0abf890b113a287e10d56b66dbab66adc1662d
commit 9f0abf890b113a287e10d56b66dbab66adc1662d
Author: Nathan VanHoudnos <nathanvan@XXXXXX>
Date:   Mon Sep 10 15:56:17 2012 -0400

    up to p. 24, including correcting spelling of my name

diff --git a/tex/MCMC-in-IRT.tex b/tex/MCMC-in-IRT.tex
index 86e67a1..b860686 100644
--- a/tex/MCMC-in-IRT.tex
+++ b/tex/MCMC-in-IRT.tex

It worked!

Step 8: So now we need to point HEAD to 9f0abf890b113a287e10d56b66dbab66adc1662d.

nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git update-ref HEAD 9f0abf890b113a287e10d56b66dbab66adc1662d

Which didn't complain.

Step 9: See what fsck says:

nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git fsck --full
Checking object directories: 100% (256/256), done.
error: refs/heads/master.u1conflict does not point to a valid object!
error: 0e31469d372551bb2f51a186fa32795e39f94d5c: invalid sha1 pointer in cache-tree

missing blob e4cf65ddf80338d50ecd4abcf1caf1de3127c229

Step 10: The invalid sha1 pointer in cache-tree seemed like it was from a (now outdated) index file (source). So I killed it and reset the repo.

nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ rm .git/index
nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git reset
Unstaged changes after reset:
M   tex/MCMC-in-IRT.tex
M   tex/recipe-example/build-example-plots.R
M   tex/recipe-example/build-failure-plots.R

Step 11: Looking at the fsck again...

nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git fsck --full
Checking object directories: 100% (256/256), done.
error: refs/heads/master.u1conflict does not point to a valid object!

dangling blob dd09f7f1f033632b7ef90876d6802f5b5fede79a

The dangling blobs are not errors. I'm not concerned with master.u1conflict, and now that it is working I don't want to touch it anymore!

Step 12: Catching up with my local edits:

nathanvan@nathanvan-N61Jq:~/workspace/mcmc-chapter$ git status

So hopefully that can be of some use to people in the future. I'm glad it worked.

Use the IS NULL operator:

Select * from tb_Employee where ename is null

    var myObj = [];
    myObj['Base'] = [];
    myObj['Base']['Base.panel.panel_base'] = {ContextParent:'',ClassParent:'',NameParent:'',Context:'Base',Class:'panel',Name:'panel_base',Visible:'',ValueIst:'',ValueSoll:'',
                                              Align:'',  AlignFrom:'',AlignTo:'',Content:'',onClick:'',Style:'',content_ger_sie:'',content_ger_du:'',content_eng:'' };
    myObj['Base']['Base.panel.panel_top']  = {ContextParent:'',ClassParent:'',NameParent:'',Context:'Base',Class:'panel',Name:'panel_base',Visible:'',ValueIst:'',ValueSoll:'',
                                              Align:'',AlignFrom:'',AlignTo:'',Content:'',onClick:'',Style:'',content_ger_sie:'',content_ger_du:'',content_eng:'' };

    myObj['SC1'] = [];
    myObj['SC1']['Base.panel.panel_base'] = {ContextParent:'',ClassParent:'',NameParent:'',Context:'Base',Class:'panel',Name:'panel_base',Visible:'',ValueIst:'',ValueSoll:'',
                                              Align:'',  AlignFrom:'',AlignTo:'',Content:'',onClick:'',Style:'',content_ger_sie:'',content_ger_du:'',content_eng:'' };
    myObj['SC1']['Base.panel.panel_top']  = {ContextParent:'',ClassParent:'',NameParent:'',Context:'Base',Class:'panel',Name:'panel_base',Visible:'',ValueIst:'',ValueSoll:'',
                                              Align:'',AlignFrom:'',AlignTo:'',Content:'',onClick:'',Style:'',content_ger_sie:'',content_ger_du:'',content_eng:'' };


    console.log(myObj);

    if ('Base' in myObj) {
      console.log('Base found');

      if ('Base.panel.panel_base' in myObj['Base'])  {
        console.log('Base.panel.panel_base found'); 


      console.log('old value: ' + myObj['Base']['Base.panel.panel_base'].Context);  
      myObj['Base']['Base.panel.panel_base'] = 'new Value';
      console.log('new value: ' + myObj['Base']['Base.panel.panel_base']);
      }
    }

Output:

• Base found
• Base.panel.panel_base found
• old value: Base
• new value: new Value

The array operation works. There is no problem.

Iteration:

     Object.keys(myObj['Base']).forEach(function(key, index) {            
        var value = objcons['Base'][key];                   
      }, myObj);

Why not use a filter?

var thevalue = 'foo';    
var exists = $('#select-box option').filter(function(){ return $(this).val() == thevalue; }).length;

Loose comparisons work because exists > 0 is true, exists == 0 is false, so you can just use

if(exists){
    // it is in the dropdown
}

Or combine it:

if($('#select-box option').filter(function(){ return $(this).val() == thevalue; }).length){
    // found
}

Or where each select dropdown has the select-boxes class this will give you a jquery object of the select(s) which contain the value:

var matched = $('.select-boxes option').filter(function(){ return $(this).val() == thevalue; }).parent();

If you want to be secure use this:<form method="post" action="<?php echo htmlspecialchars($_SERVER["PHP_SELF"]);?>">

I had a similar issue, all my app pools were stopping whenever a web request was made to them. Although I was getting the following error in the Event Viewer:

The worker process for application pool 'appPoolName' encountered an error 'Configuration file is not well-formed XML ' trying to read configuration data from file '\?\C:\inetpub\temp\apppools\appPoolName\appPoolName.config', line number '3'. The data field contains the error code.

Which told me that there were errors in the application.config at:

C:\Windows\System32\inetsrv\config\applicationHost.config

In my scenario, I edited the web.config on deploy with an element IIS clearly dislikes, the applicationHost.config scraped the web.config and inserted this bad element and wouldn't resolve until I manually removed it

I realise I'm late to the party, but I wanted a solution for this that properly handled digit grouping as well as different decimal separators for currencies. As none of these fully covered my use case I wrote my own solution which may be useful to others:

function parsePotentiallyGroupedFloat(stringValue) {
    stringValue = stringValue.trim();
    var result = stringValue.replace(/[^0-9]/g, '');
    if (/[,\.]\d{2}$/.test(stringValue)) {
        result = result.replace(/(\d{2})$/, '.$1');
    }
    return parseFloat(result);
}

This should strip out any non-digits and then check whether there was a decimal point (or comma) followed by two digits and insert the decimal point if needed.

It's worth noting that I aimed this specifically for currency and as such it assumes either no decimal places or exactly two. It's pretty hard to be sure about whether the first potential decimal point encountered is a decimal point or a digit grouping character (e.g., 1.542 could be 1542) unless you know the specifics of the current locale, but it should be easy enough to tailor this to your specific use case by changing \d{2}$ to something that will appropriately match what you expect to be after the decimal point.

If the only caveat of using __file__ is when current, relative directory is blank (ie, when running as a script from the same directory where the script is), then a trivial solution is:

import os.path
mydir = os.path.dirname(__file__) or '.'
full  = os.path.abspath(mydir)
print __file__, mydir, full

And the result:

$ python teste.py 
teste.py . /home/user/work/teste

The trick is in or '.' after the dirname() call. It sets the dir as ., which means current directory and is a valid directory for any path-related function.

Thus, using abspath() is not truly needed. But if you use it anyway, the trick is not needed: abspath() accepts blank paths and properly interprets it as the current directory.

In case of someone else is doing it in Python and it is not working, try to set it before do the imports of pycuda and tensorflow.

I.e.:

import os
os.environ["CUDA_DEVICE_ORDER"] = "PCI_BUS_ID"
os.environ["CUDA_VISIBLE_DEVICES"] = "0"
...
import pycuda.autoinit
import tensorflow as tf
...

As saw here.

For Swift 2.0

//First get the nsObject by defining as an optional anyObject

let nsObject: AnyObject? = NSBundle.mainBundle().infoDictionary!["CFBundleShortVersionString"]
let version = nsObject as! String

I'm on Linux Mint 19 (Ubuntu 18 based). I wanted to have coredump files in current folder. I had to do two things:

1. Change /proc/sys/kernel/core_pattern (by # echo "core.%p.%s.%c.%d.%P > /proc/sys/kernel/core_pattern or by # sysctl -w kernel.core_pattern=core.%p.%s.%c.%d.%P)
2. Raising limit for core file size by $ ulimit -c unlimited

That was written already in the answers, but I wrote to summarize succinctly. Interestingly changing limit did not require root privileges (as per https://askubuntu.com/questions/162229/how-do-i-increase-the-open-files-limit-for-a-non-root-user non-root can only lower the limit, so that was unexpected - comments about it are welcome).

To anyone still struggling to get the os.environ solution to work as I was, check that this is placed before you import tensorflow in your script, just like mwweb's answer:

import os
os.environ['TF_CPP_MIN_LOG_LEVEL'] = '3'  # or any {'0', '1', '2'}
import tensorflow as tf

CMS solution works great but usage/syntax can be more convenient. I suggest following

var checkNested = function(obj, structure) {

  var args = structure.split(".");

  for (var i = 0; i < args.length; i++) {
    if (!obj || !obj.hasOwnProperty(args[i])) {
      return false;
    }
    obj = obj[args[i]];
  }
  return true;
};

You can simply use object notation using dot instead of supplying multiple arguments

var test = {level1:{level2:{level3:'level3'}} };

checkNested(test, 'level1.level2.level3'); // true
checkNested(test, 'level1.level2.foo'); // false

Don't grant control to the user, it's totally unnecessay. Select permission on the database is enough. After you have created the login and the user on master (see above answers):

use YourDatabase
go
create user [YourDomain\YourUser] for login [YourDomain\YourUser] with default_schema=[dbo]
go
alter role [db_datareader] add member [YourDomain\YourUser]
go

You're synchronizing twice, which is pointless and possibly slows down the code: changes while iterating over the list need a synchronnization over the entire operation, which you are doing with synchronized (in_queue_list) Using Collections.synchronizedList() is superfluous in that case (it creates a wrapper that synchronizes individual operations).

However, since you are emptying the list completely, the iterated removal of the first element is the worst possible way to do it, sice for each element all following elements have to be copied, making this an O(n^2) operation - horribly slow for larger lists.

Instead, simply call clear() - no iteration needed.

Edit: If you need the single-method synchronization of Collections.synchronizedList() later on, then this is the correct way:

List<Record> in_queue_list = Collections.synchronizedList(in_queue);
in_queue_list.clear(); // synchronized implicitly, 

But in many cases, the single-method synchronization is insufficient (e.g. for all iteration, or when you get a value, do computations based on it, and replace it with the result). In that case, you have to use manual synchronization anyway, so Collections.synchronizedList() is just useless additional overhead.

>>> dict([('A', 1), ('B', 2), ('C', 3)])
{'A': 1, 'C': 3, 'B': 2}

My full example is here, but I will provide a summary below.

Layout

Add a .swift and .xib file each with the same name to your project. The .xib file contains your custom view layout (using auto layout constraints preferably).

Make the swift file the xib file's owner.

Code

Add the following code to the .swift file and hook up the outlets and actions from the .xib file.

import UIKit
class ResuableCustomView: UIView {

    let nibName = "ReusableCustomView"
    var contentView: UIView?

    @IBOutlet weak var label: UILabel!
    @IBAction func buttonTap(_ sender: UIButton) {
        label.text = "Hi"
    }

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)

        guard let view = loadViewFromNib() else { return }
        view.frame = self.bounds
        self.addSubview(view)
        contentView = view
    }

    func loadViewFromNib() -> UIView? {
        let bundle = Bundle(for: type(of: self))
        let nib = UINib(nibName: nibName, bundle: bundle)
        return nib.instantiate(withOwner: self, options: nil).first as? UIView
    }
}

Use it

Use your custom view anywhere in your storyboard. Just add a UIView and set the class name to your custom class name.

For a while Christopher Swasey's approach was the best approach I had found. I asked a couple of the senior devs on my team about it and one of them had the perfect solution! It satisfies every one of the concerns that Christopher Swasey so eloquently addressed and it doesn't require boilerplate subclass code(my main concern with his approach). There is one gotcha, but other than that it is fairly intuitive and easy to implement.

1. Create a custom UIView class in a .swift file to control your xib. i.e. MyCustomClass.swift
2. Create a .xib file and style it as you want. i.e. MyCustomClass.xib
3. Set the File's Owner of the .xib file to be your custom class (MyCustomClass)
4. GOTCHA: leave the class value (under the identity Inspector) for your custom view in the .xib file blank. So your custom view will have no specified class, but it will have a specified File's Owner.
5. Hook up your outlets as you normally would using the Assistant Editor.
   • NOTE: If you look at the Connections Inspector you will notice that your Referencing Outlets do not reference your custom class (i.e. MyCustomClass), but rather reference File's Owner. Since File's Owner is specified to be your custom class, the outlets will hook up and work propery.
6. Make sure your custom class has @IBDesignable before the class statement.
7. Make your custom class conform to the NibLoadable protocol referenced below.
   • NOTE: If your custom class .swift file name is different from your .xib file name, then set the nibName property to be the name of your .xib file.
8. Implement required init?(coder aDecoder: NSCoder) and override init(frame: CGRect) to call setupFromNib() like the example below.
9. Add a UIView to your desired storyboard and set the class to be your custom class name (i.e. MyCustomClass).
10. Watch IBDesignable in action as it draws your .xib in the storyboard with all of it's awe and wonder.

Here is the protocol you will want to reference:

public protocol NibLoadable {
    static var nibName: String { get }
}

public extension NibLoadable where Self: UIView {

    public static var nibName: String {
        return String(describing: Self.self) // defaults to the name of the class implementing this protocol.
    }

    public static var nib: UINib {
        let bundle = Bundle(for: Self.self)
        return UINib(nibName: Self.nibName, bundle: bundle)
    }

    func setupFromNib() {
        guard let view = Self.nib.instantiate(withOwner: self, options: nil).first as? UIView else { fatalError("Error loading \(self) from nib") }
        addSubview(view)
        view.translatesAutoresizingMaskIntoConstraints = false
        view.leadingAnchor.constraint(equalTo: self.safeAreaLayoutGuide.leadingAnchor, constant: 0).isActive = true
        view.topAnchor.constraint(equalTo: self.safeAreaLayoutGuide.topAnchor, constant: 0).isActive = true
        view.trailingAnchor.constraint(equalTo: self.safeAreaLayoutGuide.trailingAnchor, constant: 0).isActive = true
        view.bottomAnchor.constraint(equalTo: self.safeAreaLayoutGuide.bottomAnchor, constant: 0).isActive = true
    }
}

And here is an example of MyCustomClass that implements the protocol (with the .xib file being named MyCustomClass.xib):

@IBDesignable
class MyCustomClass: UIView, NibLoadable {

    @IBOutlet weak var myLabel: UILabel!

    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        setupFromNib()
    }

    override init(frame: CGRect) {
        super.init(frame: frame)
        setupFromNib()
    }

}

NOTE: If you miss the Gotcha and set the class value inside your .xib file to be your custom class, then it will not draw in the storyboard and you will get a EXC_BAD_ACCESS error when you run the app because it gets stuck in an infinite loop of trying to initialize the class from the nib using the init?(coder aDecoder: NSCoder) method which then calls Self.nib.instantiate and calls the init again.

There are lots of answer already given for this problem. Though this issue can happens for any API version, so just see the error line and find out android api version from path and platform name and go to the android sdk manager and delete related system image from sdk manager.

The document says:

Copy the file into the app/ folder of your Android Studio project, or into the app/src/{build_type} folder if you are using multiple build types.

Here's some code that I use. I found that if I set any cookie from my site, then cookies magically work in the iframe from then on.

http://developsocialapps.com/foundations-of-a-facebook-app-framework/

 if (isset($_GET['setdefaultcookie'])) {
        // top level page, set default cookie then redirect back to canvas page
        setcookie ('default',"1",0,"/");
        $url = substr($_SERVER['REQUEST_URI'],strrpos($_SERVER['REQUEST_URI'],"/")+1);
        $url = str_replace("setdefaultcookie","defaultcookieset",$url);
        $url = $facebookapp->getCanvasUrl($url);
        echo "<html>\n<body>\n<script>\ntop.location.href='".$url."';\n</script></body></html>";
        exit();
    } else if ((!isset($_COOKIE['default'])) && (!isset($_GET['defaultcookieset']))) {
        // no default cookie, so we need to redirect to top level and set
        $url = $_SERVER['REQUEST_URI'];
        if (strpos($url,"?") === false) $url .= "?";
        else $url .= "&";
        $url .= "setdefaultcookie=1";
        echo "<html>\n<body>\n<script>\ntop.location.href='".$url."';\n</script></body></html>";
        exit();
    }

Shortcut doing this on Mac: Press command+Shift+A (Action) and type "class count to use import with *" Press Enter. Enter a higher number there like 999

You might want to do it like this:

DateTime? lastPostDate =  (DateTime?)(reader.IsDbNull(3) ? null : reader[3]); 

The problem you are having is that the ternary operator wants a viable cast between the left and right sides. And null can't be cast to DateTime.

Note the above works because both sides of the ternary are object's. The object is explicitly cast to DateTime? which works: as long as reader[3] is in fact a date.

adb logcat -c

Logcat options are documented here: http://developer.android.com/tools/help/logcat.html

acme, sam from plan9,

you can use it through Plan 9 from User Space.

You just need to enable the tooltip:

$('some id or class that you add to the above a tag').popover({
    trigger: "hover" 
})

You can use a backslash at the end of a line.
So this:

a\
b\
c

will then look like:

a
b
c

Notice that there is no backslash at the end of the last line (after the 'c' character).

I use this:

function round(value, precision) {_x000D_
_x000D_
 if(precision == 0)_x000D_
  return Math.round(value);   _x000D_
_x000D_
 exp = 1;_x000D_
 for(i=0;i<precision;i++)_x000D_
  exp *= 10;_x000D_
_x000D_
 return Math.round(value*exp)/exp;_x000D_
}

To "fix" an old commit with a small change, without changing the commit message of the old commit, where OLDCOMMIT is something like 091b73a:

git add <my fixed files>
git commit --fixup=OLDCOMMIT
git rebase --interactive --autosquash OLDCOMMIT^

You can also use git commit --squash=OLDCOMMIT to edit the old commit message during rebase.

See documentation for git commit and git rebase. As always, when rewriting git history, you should only fixup or squash commits you have not yet published to anyone else (including random internet users and build servers).

Detailed explanation

• git commit --fixup=OLDCOMMIT copies the OLDCOMMIT commit message and automatically prefixes fixup! so it can be put in the correct order during interactive rebase. (--squash=OLDCOMMIT does the same but prefixes squash!.)
• git rebase --interactive will bring up a text editor (which can be configured) to confirm (or edit) the rebase instruction sequence. There is info for rebase instruction changes in the file; just save and quit the editor (:wq in vim) to continue with the rebase.
• --autosquash will automatically put any --fixup=OLDCOMMIT commits in the correct order. Note that --autosquash is only valid when the --interactive option is used.
• The ^ in OLDCOMMIT^ means it's a reference to the commit just before OLDCOMMIT. (OLDCOMMIT^ is the first parent of OLDCOMMIT.)

Optional automation

The above steps are good for verification and/or modifying the rebase instruction sequence, but it's also possible to skip/automate the interactive rebase text editor by:

• Setting GIT_SEQUENCE_EDITOR to a script.
• Creating a git alias to automatically autosquash all queued fixups.
• Creating a git alias to automatically fixup a single commit.

I want to expand on this answer. What they meant is this icon:

It opens a "real editor window" instead of the limited-feature text box in the big overview. In that editor window, special chars, linebreaks etc. are allowed and converted to the correct xml "code" when saved

this datepicker is an excellent solution. datepickers are a must if you want to avoid code injection.

The syntax '%' in %matplotlib inline is recognized by iPython (where it is set up to handle the magic methods), but not Python itself, which gives a SyntaxError. Here is given one solution.

You can call any language from java using Java Native Interface

Short answer using momentjs:

function isOverlapping(startDate1, endDate1, startDate2, endDate2){ 
    return moment(startDate1).isSameOrBefore(endDate2) && 
    moment(startDate2).isSameOrBefore(endDate1);
}

the answer is based on above answers, but its shortened.

The value of a sticky broadcast is the value that was last broadcast and is currently held in the sticky cache. This is not the value of a broadcast that was received right now. I suppose you can say it is like a browser cookie that you can access at any time. The sticky broadcast is now deprecated, per the docs for sticky broadcast methods (e.g.):

This method was deprecated in API level 21. Sticky broadcasts should not be used. They provide no security (anyone can access them), no protection (anyone can modify them), and many other problems. The recommended pattern is to use a non-sticky broadcast to report that something has changed, with another mechanism for apps to retrieve the current value whenever desired.

All modules in Python have to have a certain directory structure. You can find details here.

Create an empty file called __init__.py under the model directory, such that your directory structure would look something like that:

.
+-- project
    +-- src
        +-- hello-world.py
        +-- model
            +-- __init__.py
            +-- order.py

Also in your hello-world.py file change the import statement to the following:

from model.order import SellOrder

That should fix it

P.S.: If you are placing your model directory in some other location (not in the same directory branch), you will have to modify the python path using sys.path.

Simple Copy/Paste function, based on the boost tokenizer.

void strToIntArray(std::string string, int* array, int array_len) {
  boost::tokenizer<> tok(string);
  int i = 0;
  for(boost::tokenizer<>::iterator beg=tok.begin(); beg!=tok.end();++beg){
    if(i < array_len)
      array[i] = atoi(beg->c_str());
    i++;
}

You could do it in either of this ways , triggering an onclick on a form button like this,

<form id="myform" name="myform" method="post" action="demo2.jsp">
    <input type="text"  name="usnername" />
    <input type="text" name="password"/>        
    <input type="button" value="go" onclick="submitForm" />
</form>

And using javascript,

        function submitForm() {                
            document.forms[0].submit();
            return true;
        }

or you could also try Ajax to post your page

here is the link jQueryAjax

And also nice startup examples using Ajax and here

Hope this helps !!

Add display: block; and overflow: auto; to .my-table. This will simply cut off anything past the 280px limit you enforced. There's no way to make it "look pretty" with that requirement due to words like pélagosthrough which are wider than 280px.

Function attributes can be used to write light-weight closures that wrap code and associated data together:

#!/usr/bin/env python

SW_DELTA = 0
SW_MARK  = 1
SW_BASE  = 2

def stopwatch():
   import time

   def _sw( action = SW_DELTA ):

      if action == SW_DELTA:
         return time.time() - _sw._time

      elif action == SW_MARK:
         _sw._time = time.time()
         return _sw._time

      elif action == SW_BASE:
         return _sw._time

      else:
         raise NotImplementedError

   _sw._time = time.time() # time of creation

   return _sw

# test code
sw=stopwatch()
sw2=stopwatch()
import os
os.system("sleep 1")
print sw() # defaults to "SW_DELTA"
sw( SW_MARK )
os.system("sleep 2")
print sw()
print sw2()

use some thing like

import java.io.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;

//method to convert Document to String
public String getStringFromDocument(Document doc)
{
    try
    {
       DOMSource domSource = new DOMSource(doc);
       StringWriter writer = new StringWriter();
       StreamResult result = new StreamResult(writer);
       TransformerFactory tf = TransformerFactory.newInstance();
       Transformer transformer = tf.newTransformer();
       transformer.transform(domSource, result);
       return writer.toString();
    }
    catch(TransformerException ex)
    {
       ex.printStackTrace();
       return null;
    }
} 

Those using a buffer or tree navigation plugin, like Buffergator or NERDTree, will need to toggle these splits before destroying the current buffer - else you'll send your splits into wonkyville

I use:

"" Buffer Navigation

Where "NERDTreeToggle" in that list is the same as typing :NERDTreeToggle. You can modify this function to integrate with your own configuration.

import os

os.chdir('/your/working/path/')
dir = os.getcwd()
list = sorted(os.listdir(dir))
marks = ""

for s_list in list:
    print marks + s_list
    marks += "---"
    tree_list = sorted(os.listdir(dir + "/" + s_list))
    for i in tree_list:
        print marks + i

Just simply use this Style of DataGridRow:

<DataGrid.RowStyle>
        <Style TargetType="DataGridRow">
            <Setter Property="IsEnabled" Value="{Binding RelativeSource={RelativeSource Self},Path=IsNewItem,Mode=OneWay}" />
        </Style>
</DataGrid.RowStyle>
