You could just write to the file as you would write any normal file.

with open('csvfile.csv','wb') as file:
    for l in text:
        file.write(l)
        file.write('\n')

If just in case, it is a list of lists, you could directly use built-in csv module

import csv

with open("csvfile.csv", "wb") as file:
    writer = csv.writer(file)
    writer.writerows(text)

var map_marker = $(".map-marker").children("img").attr("src") var pinImage = new google.maps.MarkerImage(map_marker);

     var marker = new google.maps.Marker({
      position: uluru,
      map: map,
      icon: pinImage
    });
  }

What context/language? Some languages use / as the pattern delimiter, so yes, you need to escape it, depending on which language/context. You escape it by putting a backward slash in front of it: \/ For some languages (like PHP) you can use other characters as the delimiter and therefore you don't need to escape it. But AFAIK in all languages, the only special significance the / has is it may be the designated pattern delimiter.

Easiest way to achieve this would be :

CSS :

label{ float: left; }

span
{
    display: block;
    overflow: hidden;
    padding-right: 5px;
    padding-left: 10px;
}

span > input{ width: 100%; }

HTML :

<fieldset>
    <label>label</label><span><input type="text" /></span>
    <label>longer label</label><span><input type="text" /></span>
</fieldset>

Looks like : http://jsfiddle.net/JwfRX/

Add:

using System.Linq;

to the top of your file.

And then:

Car[] carList = ...
var carMake = 
    from item in carList
    where item.Model == "bmw" 
    select item.Make;

or if you prefer the fluent syntax:

var carMake = carList
    .Where(item => item.Model == "bmw")
    .Select(item => item.Make);

Things to pay attention to:

• The usage of item.Make in the select clause instead if s.Make as in your code.
• You have a whitespace between item and .Model in your where clause

You can not convert to string if your integer value is zero or starts with zero (in which case 1st zero will be neglected). Try change.

int NUM=null;

I don't see any up to date info listed here, so here goes:

To answer this question now, 2 favicons will not do it if you want your icon to look great everywhere. See the sizes below:

16 x 16 – Standard size for browsers

72 x 72 – iPad touch up to iOS6
76 x 76 – iOS7
96 x 96 – GoogleTV
114 x 114 – iPhone retina touch up to iOS6

For completeness, difflib in the standard-library provides loads of sequence-comparison utilities. For instance find_longest_match which finds the longest common substring when used on strings. Example use:

from difflib import SequenceMatcher

string1 = "apple pie available"
string2 = "come have some apple pies"

match = SequenceMatcher(None, string1, string2).find_longest_match(0, len(string1), 0, len(string2))

print(match)  # -> Match(a=0, b=15, size=9)
print(string1[match.a: match.a + match.size])  # -> apple pie
print(string2[match.b: match.b + match.size])  # -> apple pie

http://www.unicode.org is the place to look for symbol names.

? BLACK CIRCLE        25CF
? MEDIUM BLACK CIRCLE 26AB
? BLACK LARGE CIRCLE  2B24

or even:

 NEW MOON SYMBOL   1F311

Good luck finding a font that supports them all. Only one shows up in Windows 7 with Chrome.

Use struct.pack to convert the integer values into binary bytes, then write the bytes. E.g.

newFile.write(struct.pack('5B', *newFileBytes))

However I would never give a binary file a .txt extension.

The benefit of this method is that it works for other types as well, for example if any of the values were greater than 255 you could use '5i' for the format instead to get full 32-bit integers.

:last-child will not work if the element is not the VERY LAST element

In addition to Harry's answer, I think it's crucial to add/emphasize that :last-child will not work if the element is not the VERY LAST element in a container. For whatever reason it took me hours to realize that, and even though Harry's answer is very thorough I couldn't extract that information from "The last-child selector is used to select the last child element of a parent."

Suppose this is my selector: a:last-child {}

This works:

<div>
    <a></a>
    <a>This will be selected</a>
</div>

This doesn't:

<div>
    <a></a>
    <a>This will no longer be selected</a>
    <div>This is now the last child :'( </div>
</div>

It doesn't because the a element is not the last element inside its parent.

It may be obvious, but it was not for me...

You also run into this issue when you are creating routine in a class module.

When you try to run the code externally, you get this error.
You can't assign macro to button to a member of a class module either.

If you try to run from within the code by pressing green play button you will also see the same error.

Either move the routine in to a regular module or create a new routine in a regular module that calls the class member.

dicts = {}
keys = range(4)
values = ["Hi", "I", "am", "John"]
for i in keys:
        dicts[i] = values[i]
print(dicts)

alternatively

In [7]: dict(list(enumerate(values)))
Out[7]: {0: 'Hi', 1: 'I', 2: 'am', 3: 'John'}

Most commonly, you'd use:

import random
random.uniform(a, b) # range [a, b) or [a, b] depending on floating-point rounding

Python provides other distributions if you need.

If you have numpy imported already, you can used its equivalent:

import numpy as np
np.random.uniform(a, b) # range [a, b)

Again, if you need another distribution, numpy provides the same distributions as python, as well as many additional ones.

Check your bundle identifier and your profiles. If you have a profile for a specific bundle identifier and no team ones and your bundle identifier does not match it will give you that error.

Bundle identifier is in General section of your project properties and the profiles you can check in build settings.

As in Swift 3.x for upload image with parameter we can use below alamofire upload method-

static func uploadImageData(inputUrl:String,parameters:[String:Any],imageName: String,imageFile : UIImage,completion:@escaping(_:Any)->Void) {

        let imageData = UIImageJPEGRepresentation(imageFile , 0.5)

        Alamofire.upload(multipartFormData: { (multipartFormData) in

            multipartFormData.append(imageData!, withName: imageName, fileName: "swift_file\(arc4random_uniform(100)).jpeg", mimeType: "image/jpeg")

            for key in parameters.keys{
                let name = String(key)
                if let val = parameters[name!] as? String{
                    multipartFormData.append(val.data(using: .utf8)!, withName: name!)
                }
            }
        }, to:inputUrl)
        { (result) in
            switch result {
            case .success(let upload, _, _):

                upload.uploadProgress(closure: { (Progress) in
                })

                upload.responseJSON { response in

                    if let JSON = response.result.value {
                        completion(JSON)
                    }else{
                        completion(nilValue)
                    }
                }

            case .failure(let encodingError):
                completion(nilValue)
            }

        }

    }

Note: Additionally if our parameter is array of key-pairs then we can use

 var arrayOfKeyPairs = [[String:Any]]()
 let json = try? JSONSerialization.data(withJSONObject: arrayOfKeyPairs, options: [.prettyPrinted])
 let jsonPresentation = String(data: json!, encoding: .utf8)

Try this

input::-webkit-input-placeholder { /* WebKit browsers */_x000D_
    color:    #f51;_x000D_
}_x000D_
input:-moz-placeholder { /* Mozilla Firefox 4 to 18 */_x000D_
    color:    #f51;_x000D_
}_x000D_
input::-moz-placeholder { /* Mozilla Firefox 19+ */_x000D_
    color:    #f51;_x000D_
}_x000D_
input:-ms-input-placeholder { /* Internet Explorer 10+ */_x000D_
    color:    #f51;_x000D_
}

<input type="text" placeholder="Value" />

I always include the js files in the head of the html document and them in the action just call the javascript function. Something like this:

action="javascript:checkout()"

You try this?

Don't forget include the script reference in the html head.

I don't know cause of that works in firefox. Regards.

If you use MyISAM tables, the fastest way is querying directly the stats:

select table_name, table_rows 
     from information_schema.tables 
where 
     table_schema='databasename' and 
     table_name in ('user_table','cat_table','course_table')

If you have InnoDB you have to query with count() as the reported value in information_schema.tables is wrong.

Here is a pure css version

.example-print {_x000D_
    display: none;_x000D_
}_x000D_
@media print {_x000D_
   .example-screen {_x000D_
       display: none;_x000D_
    }_x000D_
    .example-print {_x000D_
       display: block;_x000D_
    }_x000D_
}

<div class="example-screen">You only see me in the browser</div>_x000D_
_x000D_
<div class="example-print">You only see me in the print</div>

I found that having too many and's would return incorrect results (for .NET 1.1 anyway)

DataRow[] results = table.Select("A = 'foo' AND B = 'bar' AND C = 'baz' and D ='fred' and E = 'marg'"); 

In my case A was the 12th field in a table and the select was effectively ignoring it.

However if I did

DataRow[] results = table.Select("A = 'foo' AND (B = 'bar' AND C = 'baz' and D ='fred' and E = 'marg')"); 

The filter worked correctly!

In addition to what John Skeet said, here's an overview of the Java 7 project. It includes a list and description of the features.

Note: JDK 7 was released on July 28, 2011, so you should now go to the official java SE site.

I created my AppIcon catalog manually and had all the correct icons in it, but my project was not using it as the icon catalog. On the project's General tab (where you can set the project name and version number), there was an entry for App Icons Source, but no way to select the catalog I created. I had to click the button to create a new catalog, then delete that new catalog, and then the button changed to a menu where I could select the existing catalog.

Try using this:

for k in range(1,c+1,2):

this works, and can be adapted for weeks or anyother frequency i.e. weekly, quarterly etc...

=SUMIFS(B12:B11652,A12:A11652,">="&DATE(YEAR(C12),MONTH(C12),1),A12:A11652,"<"&DATE(YEAR(C12),MONTH(C12)+1,1))

a = dict(one=1, two=2, three=3)

Providing keyword arguments as in this example only works for keys that are valid Python identifiers. Otherwise, any valid keys can be used.

You could deploy a custom BeanPostProcessor in your application context to do it. Or if you don't mind implementing a Spring interface in your bean, you could use the InitializingBean interface or the "init-method" directive (same link).

Returns true if comes 'y', '1', 'true', 'on'or whatever you add in similar way

boolean getValue(String value) {
  return ("Y".equals(value.toUpperCase()) 
      || "1".equals(value.toUpperCase())
      || "TRUE".equals(value.toUpperCase())
      || "ON".equals(value.toUpperCase()) 
     );
}

My issue was with a Microsoft MediaRoom IPTV application. It turns out that MPF MRML applications don't support cookies; changing to use cookieless sessions in the web.config solved my issue

<sessionState cookieless="true"  />

Here's a REALLY old article about it: Cookieless ASP.NET

Thanks Kip, for those who may be looking to achieve the same using $(this) whilst iterating or associating within a function:

$("label[for="+$(this).attr("id")+"]").addClass( "orienSel" );

I looked for a while whilst working this project but couldn't find a good example so I hope this helps others who may be looking to resolve the same issue.

In the example above, my objective was to hide the radio inputs and style the labels to provide a slicker user experience (changing the orientation of the flowchart).

You can see an example here

If you like the example, here is the css:

.orientation {      position: absolute; top: -9999px;   left: -9999px;}
    .orienlabel{background:#1a97d4 url('http://www.ifreight.solutions/process.html/images/icons/flowChart.png') no-repeat 2px 5px; background-size: 40px auto;color:#fff; width:50px;height:50px;display:inline-block; border-radius:50%;color:transparent;cursor:pointer;}
    .orR{   background-position: 9px -57px;}
    .orT{   background-position: 2px -120px;}
    .orB{   background-position: 6px -177px;}

    .orienSel {background-color:#323232;}

and the relevant part of the JavaScript:

function changeHandler() {
    $(".orienSel").removeClass( "orienSel" );
    if(this.checked) {
        $("label[for="+$(this).attr("id")+"]").addClass( "orienSel" );
    }
};

An alternate root to the original question, given the label follows the input, you could go with a pure css solution and avoid using JavaScript altogether...:

input[type=checkbox]:checked+label {}

Additionally, if you've started using yarn, in place of npm:
yarn remove <package-name>

Is the equivalent of:
npm uninstall <package-name> --save

This will
- remove the package from package.json, as well as
- uninstall it from your project's node-modules folder

Shorter:

User.where("id > 200")

When you read() the file, you may get a newline character '\n' in your string. Try either

if UserInput.strip() == 'List contents': 

or

if 'List contents' in UserInput: 

Also note that your second file open could also use with:

with open('/Users/.../USER_INPUT.txt', 'w+') as UserInputFile:     if UserInput.strip() == 'List contents': # or if s in f:         UserInputFile.write("ls")     else:         print "Didn't work" 

On the standard front:

• a translation unit is the combination of a source files, included headers and source files less any source lines skipped by conditional inclusion preprocessor directive.

• the standard defines 9 phases in the translation. The first four correspond to preprocessing, the next three are the compilation, the next one is the instantiation of templates (producing instantiation units) and the last one is the linking.

In practice the eighth phase (the instantiation of templates) is often done during the compilation process but some compilers delay it to the linking phase and some spread it in the two.

Two generic ways to do the same thing... I'm not aware of any specific open solutions to do this, but it'd be rather trivial to do.

You could write a daily or weekly cron/jenkins job to scrape the previous time period's email from the archive looking for your keyworkds/combinations. Sending a batch digest with what it finds, if anything.

But personally, I'd Setup a specific email account to subscribe to the various security lists you're interested in. Add a simple automated script to parse the new emails for various keywords or combinations of keywords, when it finds a match forward that email on to you/your team. Just be sure to keep the keywords list updated with new products you're using.

You could even do this with a gmail account and custom rules, which is what I currently do, but I have setup an internal inbox in the past with a simple python script to forward emails that were of interest.

Marc's answer is the approach I use for this, but for simplicity (and a friendlier API?) you can define a property in the collection base class if you have one such as:

public abstract class CollectionBase<T> : IList<T>
{
   ...

   public Type ElementType
   {
      get
      {
         return typeof(T);
      }
   }
}

I have found this approach useful, and is easy to understand for any newcomers to generics.

For Mysql, we have a limitation. In the driver Mysql doc, we have :

The following are some known issues and limitations for MySQL Connector/J: When Connector/J retrieves timestamps for a daylight saving time (DST) switch day using the getTimeStamp() method on the result set, some of the returned values might be wrong. The errors can be avoided by using the following connection options when connecting to a database:

useTimezone=true
useLegacyDatetimeCode=false
serverTimezone=UTC

So, when we do not use this parameters and we call setTimestamp or getTimestamp with calendar or without calendar, we have the timestamp in the jvm timezone.

Example :

The jvm timezone is GMT+2. In the database, we have a timestamp : 1461100256 = 19/04/16 21:10:56,000000000 GMT

Properties props = new Properties();
props.setProperty("user", "root");
props.setProperty("password", "");
props.setProperty("useTimezone", "true");
props.setProperty("useLegacyDatetimeCode", "false");
props.setProperty("serverTimezone", "UTC");
Connection con = DriverManager.getConnection(conString, props);
......
Calendar nowGMT = Calendar.getInstance(TimeZone.getTimeZone("GMT"));
Calendar nowGMTPlus4 = Calendar.getInstance(TimeZone.getTimeZone("GMT+4"));
......
rs.getTimestamp("timestampColumn");//Oracle driver convert date to jvm timezone and Mysql convert date to GMT (specified in the parameter)
rs.getTimestamp("timestampColumn", nowGMT);//convert date to GMT 
rs.getTimestamp("timestampColumn", nowGMTPlus4);//convert date to GMT+4 timezone

The first method returns : 1461100256000 = 19/04/2016 - 21:10:56 GMT

The second method returns : 1461100256000 = 19/04/2016 - 21:10:56 GMT

The third method returns : 1461085856000 = 19/04/2016 - 17:10:56 GMT

Instead of Oracle, when we use the same calls, we have :

The first method returns : 1461093056000 = 19/04/2016 - 19:10:56 GMT

The second method returns : 1461100256000 = 19/04/2016 - 21:10:56 GMT

The third method returns : 1461085856000 = 19/04/2016 - 17:10:56 GMT

NB : It is not necessary to specify the parameters for Oracle.

I have installed laravel on EC2 instance and have spent 3 days to fix the permission error and at last fixed it. So I want to share this experience with other one.

1. user problem When I logged in ec2 instance, my username is ec2-user and usergroup is ec2-user. And the website works under of httpd user: apache: apache so we should set the permission for apache.

2. folder and file permission A. folder structure first, you should make sure that you have such folder structure like this under storage

   storage

   • framework
     • cache
     • sessions
     • views
   • logs The folder structure can be different according to the laravel version you use. my laravel version is 5.2 and you could find the appropriate structure according to your version.

B. permission At first, I see the instructions to set 777 under storage to remove file_put_contents: failed to open stream error. So i setup permission 777 to storage chmod -R 777 storage But the error was not fixed. here, you should consider one: who writes files to storage/ sessions and views. That is not ec2-user, but apache. Yes, right. "apache" user writes file (session file, compiled view file) to the session and view folder. So you should give apache to write permission to these folder. By default: SELinux say the /var/www folder should be read-only by the apache deamon.

So for this, we can set the selinux as 0: setenforce 0

This can solve problem temporally, but this makes the mysql not working. so this is not so good solution.

You can set a read-write context to the storage folder with: (remember to setenforce 1 to test it out)

chcon -Rt httpd_sys_content_rw_t storage/

Then your problem will be fixed.

3. and don't forget this composer update php artisan cache:clear

   These commands will be useful after or before.

   I hope you save your time. Good luck. Hacken

If you are doing this in more than one place in your application it would make sense to use a client-side JSON database because creating custom search functions is messy and less maintainable than the alternative.

Check out ForerunnerDB which provides you with a very powerful client-side JSON database system and includes a very simple query language to help you do exactly what you are looking for:

// Create a new instance of ForerunnerDB and then ask for a database
var fdb = new ForerunnerDB(),
    db = fdb.db('myTestDatabase'),
    coll;

// Create our new collection (like a MySQL table) and change the default
// primary key from "_id" to "id"
coll = db.collection('myCollection', {primaryKey: 'id'});

// Insert our records into the collection
coll.insert([
    {"name":"my Name","id":12,"type":"car owner"},
    {"name":"my Name2","id":13,"type":"car owner2"},
    {"name":"my Name4","id":14,"type":"car owner3"},
    {"name":"my Name4","id":15,"type":"car owner5"}
]);

// Search the collection for the string "my nam" as a case insensitive
// regular expression - this search will match all records because every
// name field has the text "my Nam" in it
var searchResultArray = coll.find({
    name: /my nam/i
});

console.log(searchResultArray);

/* Outputs
[
    {"name":"my Name","id":12,"type":"car owner"},
    {"name":"my Name2","id":13,"type":"car owner2"},
    {"name":"my Name4","id":14,"type":"car owner3"},
    {"name":"my Name4","id":15,"type":"car owner5"}
]

sqlplus user/password@sid < sqlfile.sql

This will also work from the DOS command line. In this case the file sqlfile.sql contains the SQL you wish to execute.

I ran into this same issue recently, posted the my solution also here: Preventing element from displaying on top of footer when using position:fixed

You can achieve a solution leveraging the position property of the element with jQuery, switching between the default value (static for divs), fixed and absolute. You will also need a container element for your fixed element. Finally, in order to prevent the fixed element to go over the footer, this container element can't be the parent of the footer.

The javascript part involves calculating the distance in pixels between your fixed element and the top of the document, and comparing it with the current vertical position of the scrollbar relatively to the window object (i.e. the number of pixels above that are hidden from the visible area of the page) every time the user scrolls the page. When, on scrolling down, the fixed element is about to disappear above, we change its position to fixed and stick on top of the page.

This causes the fixed element to go over the footer when we scroll to the bottom, especially if the browser window is small. Therefore, we will calculate the distance in pixels of the footer from the top of the document and compare it with the height of the fixed element plus the vertical position of the scrollbar: when the fixed element is about to go over the footer, we will change its position to absolute and stick at the bottom, just over the footer.

Here's a generic example.

The HTML structure:

<div id="content">
    <div id="leftcolumn">
        <div class="fixed-element">
            This is fixed 
        </div>
    </div>
    <div id="rightcolumn">Main content here</div>
    <div id="footer"> The footer </div>
</div>  

The CSS:

#leftcolumn {
    position: relative;
}
.fixed-element {
    width: 180px;
}
.fixed-element.fixed {
    position: fixed;
    top: 20px;
}
.fixed-element.bottom {
    position: absolute;
    bottom: 356px; /* Height of the footer element, plus some extra pixels if needed */
}

The JS:

// Position of fixed element from top of the document
var fixedElementOffset = $('.fixed-element').offset().top;
// Position of footer element from top of the document.
// You can add extra distance from the bottom if needed,
// must match with the bottom property in CSS
var footerOffset = $('#footer').offset().top - 36;

var fixedElementHeight = $('.fixed-element').height(); 

// Check every time the user scrolls
$(window).scroll(function (event) {

    // Y position of the vertical scrollbar
    var y = $(this).scrollTop();

    if ( y >= fixedElementOffset && ( y + fixedElementHeight ) < footerOffset ) {
        $('.fixed-element').addClass('fixed');
        $('.fixed-element').removeClass('bottom');          
    }
    else if ( y >= fixedElementOffset && ( y + fixedElementHeight ) >= footerOffset ) {
        $('.fixed-element').removeClass('fixed');           
        $('.fixed-element').addClass('bottom');
    }
    else {
        $('.fixed-element').removeClass('fixed bottom');
    }

 });

Ok so I was having this issue where I tried several different options.

I was able to apply it... eventually here is my working code

I wanted this to apply to my entire website so I put it at the top of the css doc. above all of the Div tags (not that it matters, just know that any individual fonts you assign post your script will take precedence)

@font-face{
    font-family: "Ubuntu-LI";
    src: url("/fonts/Ubuntu/(Ubuntu-LI.ttf"),
    url("../fonts/Ubuntu/Ubuntu-LI.ttf");
}

*{
    font-family:"Ubuntu-LI";
}

If i then wanted all of my H1 tags to be something else lets say sans sarif I would do something like

h1{
   font-family: Sans-sarif;
}

From which case only my H1 tags would be the sans-sarif font and the rest of my page would be the Ubuntu-LI font

:last-child is CSS3 and has no IE support while :first-child is CSS2, I believe the following is the safe way to implement it using jquery

$('li').last().addClass('someClass');

Batch script:

@echo off

set /p host=host Address: 
set logfile=Log_%host%.log

echo Target Host = %host% >%logfile%
for /f "tokens=*" %%A in ('ping %host% -n 1 ') do (echo %%A>>%logfile% && GOTO Ping)
:Ping
for /f "tokens=* skip=2" %%A in ('ping %host% -n 1 ') do (
    echo %date% %time:~0,2%:%time:~3,2%:%time:~6,2% %%A>>%logfile%
    echo %date% %time:~0,2%:%time:~3,2%:%time:~6,2% %%A
    timeout 1 >NUL 
    GOTO Ping)

This script will ask for which host to ping. Ping output is output to screen and log file. Example log file output:

Target Host = www.nu.nl
Pinging nu-nl.gslb.sanomaservices.nl [62.69.166.210] with 32 bytes of data:

Log file is named LOG_[hostname].log and written to same folder as the script.

you can path object and path seprated with "."

function checkPathExist(obj, path) {_x000D_
  var pathArray =path.split(".")_x000D_
  for (var i of pathArray) {_x000D_
    if (Reflect.get(obj, i)) {_x000D_
      obj = obj[i];_x000D_
  _x000D_
    }else{_x000D_
  return false;_x000D_
    }_x000D_
  }_x000D_
 return true;_x000D_
}_x000D_
_x000D_
var test = {level1:{level2:{level3:'level3'}} };_x000D_
_x000D_
console.log('level1.level2.level3 => ',checkPathExist(test, 'level1.level2.level3')); // true_x000D_
console.log( 'level1.level2.foo => ',checkPathExist(test, 'level1.level2.foo')); // false

I was having problems with a new install of VS with an x64 project - for Visual Studio 2013, Visual Studio 2015 and Visual Studio 2017:

Tools
  -> Options
   -> Projects and Solutions
    -> Web Projects
     -> Check "Use the 64 bit version of IIS Express for web sites and projects"

I use the suffixes option in .merge():

dfNew = df.merge(df2, left_index=True, right_index=True,
                 how='outer', suffixes=('', '_y'))
dfNew.drop(dfNew.filter(regex='_y$').columns.tolist(),axis=1, inplace=True)

Thanks @ijoseph

I typically see performance increases when filtering on the join. Especially if you can join on indexed columns for both tables. You should be able to cut down on logical reads with most queries doing this too, which is, in a high volume environment, a much better performance indicator than execution time.

I'm always mildly amused when someone shows their SQL benchmarking and they've executed both versions of a sproc 50,000 times at midnight on the dev server and compare the average times.

From http://docs.python.org/library/csv.html#csv.writer:

If csvfile is a file object, it must be opened with the ‘b’ flag on platforms where that makes a difference.

In other words, when opening the file you pass 'wb' as opposed to 'w'.
You can also use a with statement to close the file when you're done writing to it.
Tested example below:

from __future__ import with_statement # not necessary in newer versions
import csv
headers=['id', 'year', 'activity', 'lineitem', 'datum']
with open('file3.csv','wb') as fou: # note: 'wb' instead of 'w'
    output = csv.DictWriter(fou,delimiter=',',fieldnames=headers)
    output.writerow(dict((fn,fn) for fn in headers))
    output.writerows(rows)

Just follow the official instructions from ShellEd's InstallGuide

Just call the action no need for redirect to action or the new keyword for model.

 [HttpPost]
    public ActionResult FillStudent(Student student1)
    {
        return GetStudent(student1); //this will also work
    }
    public ActionResult GetStudent(Student student)
    {
        return View(student);
    }

Clicking a radio button should trigger an event that either:

1. calls setState, if you only want the selection knowledge to be local, or
2. calls a callback that has been passed in from above self.props.selectionChanged(...)

In the first case, the change is state will trigger a re-render and you can do
<td>chosen site name {this.state.chosenSiteName} </td>

in the second case, the source of the callback will update things to ensure that down the line, your SearchResult instance will have chosenSiteName and chosenAddress set in it's props.

From the documentation for ast.literal_eval():

Safely evaluate an expression node or a string containing a Python expression. The string or node provided may only consist of the following Python literal structures: strings, numbers, tuples, lists, dicts, booleans, and None.

Decimal isn't on the list of things allowed by ast.literal_eval().

Just 2 things I think make it ALWAYS preferable to use a # Temp Table rather then a CTE are:

1. You can not put a primary key on a CTE so the data being accessed by the CTE will have to traverse each one of the indexes in the CTE's tables rather then just accessing the PK or Index on the temp table.

2. Because you can not add constraints, indexes and primary keys to a CTE they are more prone to bugs creeping in and bad data.

-onedaywhen yesterday

Here is an example where #table constraints can prevent bad data which is not the case in CTE's

DECLARE @BadData TABLE ( 
                       ThisID int
                     , ThatID int );
INSERT INTO @BadData
       ( ThisID
       , ThatID
       ) 
VALUES
       ( 1, 1 ),
       ( 1, 2 ),
       ( 2, 2 ),
       ( 1, 1 );

IF OBJECT_ID('tempdb..#This') IS NOT NULL
    DROP TABLE #This;
CREATE TABLE #This ( 
             ThisID int NOT NULL
           , ThatID int NOT NULL
                        UNIQUE(ThisID, ThatID) );
INSERT INTO #This
SELECT * FROM @BadData;
WITH This_CTE
     AS (SELECT *
           FROM @BadData)
     SELECT *
       FROM This_CTE;

Markdown should have this capability, but it doesn't. Instead, you're stuck with language-specific Markdown supersets:

PHP: Markdown Extra
Ruby: Kramdown, Maruku

But if you need to abide by true Markdown syntax, you're stuck with inserting raw HTML, which is less ideal.

Here is another simple trick using Jquery!!

HTML

<form id="hobbieform">
        <div>
            <input type="checkbox" name="hobbies[]">Coding
            <input type="checkbox" name="hobbies[]">Gaming
            <input type="checkbox" name="hobbies[]">Driving
        </div>
</form>

JQuery

$('#hobbieform').on("submit", function (e) {
    var arr = $(this).serialize().toString();
    if(arr.indexOf("hobbies") < 0){
        e.preventDefault();
        alert("You must select at least one hobbie");
    }
});

That's all.. this works because if none of the checkbox is selected, nothing as regards the checkbox group(including its name) is posted to the server

The built in clean function can also be helpful...

git clean -fd

The second sample assigns a unique ID to the element in question. This element can then be manipulated or accessed using DHTML.

The first one, on the other hand, sets a named location within the document, akin to a bookmark. Attached to an "anchor", it makes perfect sense.

To know if simple array has duplicates we can compare first and last indexes of the same value:

The function:

var hasDupsSimple = function(array) {

    return array.some(function(value) {                            // .some will break as soon as duplicate found (no need to itterate over all array)
       return array.indexOf(value) !== array.lastIndexOf(value);   // comparing first and last indexes of the same value
    })
}

Tests:

hasDupsSimple([1,2,3,4,2,7])
// => true

hasDupsSimple([1,2,3,4,8,7])
// => false

hasDupsSimple([1,"hello",3,"bye","hello",7])
// => true

For an array of objects we need to convert the objects values to a simple array first:

Converting array of objects to the simple array with map:

var hasDupsObjects = function(array) {

  return array.map(function(value) {
    return value.suit + value.rank

  }).some(function(value, index, array) { 
       return array.indexOf(value) !== array.lastIndexOf(value);  
     })
}

Tests:

var cardHand = [
  { "suit":"spades", "rank":"ten" },
  { "suit":"diamonds", "rank":"ace" },
  { "suit":"hearts", "rank":"ten" },
  { "suit":"clubs", "rank":"two" },
  { "suit":"spades", "rank":"three" },
]

hasDupsObjects(cardHand);
// => false

var cardHand2 = [
  { "suit":"spades", "rank":"ten" },
  { "suit":"diamonds", "rank":"ace" },
  { "suit":"hearts", "rank":"ten" },
  { "suit":"clubs", "rank":"two" },
  { "suit":"spades", "rank":"ten" },
]

hasDupsObjects(cardHand2);
// => true

you can use the simpleDateFormat to parse the string date.

Download and install IOBIT uninstaller: http://www.iobit.com/advanceduninstaller.php, find the date in which you install Visual Studio and select all programas from that date r elated to VS. Then run de batch uninstaller. It is not a fully automated solution but it is a lot quicker than going one by one int he add / remove programs in Windows. It even has a power scan to clean the registry.

So basically I just made another div to wrap the pink and yellow, and I make that div have a float:left on it. The blue div has a float:right on it.

I was looking for fast way to do the subject, so I made some experiments with suggested ways. And I was surprised by results, so I want to share it with you.

Experiments were done using pythonbenchmark tool and with

a = range(1,50000) # Source list
b = range(1,15000) # Items to remove

Results:

 def comprehension(a, b):
     return [x for x in a if x not in b]

5 tries, average time 12.8 sec

def filter_function(a, b):
    return filter(lambda x: x not in b, a)

5 tries, average time 12.6 sec

def modification(a,b):
    for x in b:
        try:
            a.remove(x)
        except ValueError:
            pass
    return a

5 tries, average time 0.27 sec

def set_approach(a,b):
    return list(set(a)-set(b))

5 tries, average time 0.0057 sec

Also I made another measurement with bigger inputs size for the last two functions

a = range(1,500000)
b = range(1,100000)

And the results:

For modification (remove method) - average time is 252 seconds For set approach - average time is 0.75 seconds

So you can see that approach with sets is significantly faster than others. Yes, it doesn't keep similar items, but if you don't need it - it's for you. And there is almost no difference between list comprehension and using filter function. Using 'remove' is ~50 times faster, but it modifies source list. And the best choice is using sets - it's more than 1000 times faster than list comprehension!

Process.WaitForExit should be just what you're looking for I think.

Jenv on Mac Sierra:

if not working after install, do this bug fix to add java executable to path

export PATH="$HOME/.jenv/shims:$PATH"

even though eval "$(jenv init -)" could do this job. The reason is /bin folder is not there anymore as describe in it's homepage, but shim folder is used as /bin instead.

• Make sure ~/.jenv is there
• which java may print /Library/...
• jenv global 1.8
• jenv shell 1.8

Eventually, which java gives you:

/Users/xxxx/.jenv/shims/java

The technical limitations with using PUT and DELETE requests does not lie with PHP or Apache2; it is instead on the burden of the browser to sent those types of requests.

Simply putting <form action="" method="PUT"> will not work because there are no browsers that support that method (and they would simply default to GET, treating PUT the same as it would treat gibberish like FDSFGS). Sadly those HTTP verbs are limited to the realm of non-desktop application browsers (ie: web service consumers).

If you have entered 'Debug server host & port for device' in Dev Settings, make sure you remove what you have entered.

SSIS (SQL Server Integration Services) is an upgrade of DTS (Data Transformation Services), which is a feature of the previous version of SQL Server. SSIS packages can be created in BIDS (Business Intelligence Development Studio). These can be used to merge data from heterogeneous data sources into SQL Server. They can also be used to populate data warehouses, to clean and standardize data, and to automate administrative tasks.

SQL Server Integration Services (SSIS) is a component of Microsoft SQL Server 2005. It replaces Data Transformation Services, which has been a feature of SQL Server since Version 7.0. Unlike DTS, which was included in all versions, SSIS is only available in the "Standard" and "Enterprise" editions. Integration Services provides a platform to build data integration and workflow applications. The primary use for SSIS is data warehousing as the product features a fast and flexible tool for data extraction, transformation, and loading (ETL).). The tool may also be used to automate maintenance of SQL Server databases, update multidimensional cube data, and perform other functions.

google.maps.event.trigger($("#div_ID")[0], 'resize');

If you don't have variable map available, it should be the first element (unless you did something stupid) in the div that contains GMAP.

public static Bitmap resizeAndCropCenter(Bitmap bitmap, int size, boolean recycle) {
    int w = bitmap.getWidth();
    int h = bitmap.getHeight();
    if (w == size && h == size) return bitmap;
    // scale the image so that the shorter side equals to the target;
    // the longer side will be center-cropped.
    float scale = (float) size / Math.min(w,  h);
    Bitmap target = Bitmap.createBitmap(size, size, getConfig(bitmap));
    int width = Math.round(scale * bitmap.getWidth());
    int height = Math.round(scale * bitmap.getHeight());
    Canvas canvas = new Canvas(target);
    canvas.translate((size - width) / 2f, (size - height) / 2f);
    canvas.scale(scale, scale);
    Paint paint = new Paint(Paint.FILTER_BITMAP_FLAG | Paint.DITHER_FLAG);
    canvas.drawBitmap(bitmap, 0, 0, paint);
    if (recycle) bitmap.recycle();
    return target;
}

private static Bitmap.Config getConfig(Bitmap bitmap) {
    Bitmap.Config config = bitmap.getConfig();
    if (config == null) {
        config = Bitmap.Config.ARGB_8888;
    }
    return config;
}

If it's ok to use direct casting afterwards, I guess you can use the System.Enum base class in your method, wherever necessary. You just need to replace the type parameters carefully. So the method implementation would be like:

public static class EnumUtils
{
    public static Enum GetEnumFromString(string value, Enum defaultValue)
    {
        if (string.IsNullOrEmpty(value)) return defaultValue;
        foreach (Enum item in Enum.GetValues(defaultValue.GetType()))
        {
            if (item.ToString().ToLower().Equals(value.Trim().ToLower())) return item;
        }
        return defaultValue;
    }
}

Then you can use it like:

var parsedOutput = (YourEnum)EnumUtils.GetEnumFromString(someString, YourEnum.DefaultValue);

Take a look at Directory.GetFiles Method (String, String) (MSDN).

This method returns all the files as an array of filenames.

The split() method in javascript accepts two parameters: a separator and a limit. The separator specifies the character to use for splitting the string. If you don't specify a separator, the entire string is returned, non-separated. But, if you specify the empty string as a separator, the string is split between each character.

Therefore:

s.split('')

will have the effect you seek.

In order for new T to compile, T must be a complete type. In your case, when you say new tile_tree_apple inside the definition of tile_tree::tick, tile_tree_apple is incomplete (it has been forward declared, but its definition is later in your file). Try moving the inline definitions of your functions to a separate source file, or at least move them after the class definitions.

Something like:

class A
{
    void f1();
    void f2();
};
class B
{
   void f3();
   void f4();
};

inline void A::f1() {...}
inline void A::f2() {...}
inline void B::f3() {...}
inline void B::f4() {...}

When you write your code this way, all references to A and B in these methods are guaranteed to refer to complete types, since there are no more forward references!

A simple graphic makes this clearer:

git diff

Shows the changes between the working directory and the index. This shows what has been changed, but is not staged for a commit.

git diff --cached

Shows the changes between the index and the HEAD (which is the last commit on this branch). This shows what has been added to the index and staged for a commit.

git diff HEAD

Shows all the changes between the working directory and HEAD (which includes changes in the index). This shows all the changes since the last commit, whether or not they have been staged for commit or not.

Also:

There is a bit more detail on 365Git.

When creating a text file you can use the following code:

System.IO.File.WriteAllText("c:\test.txt", "all of your content here");

Using the code from your comment. The file(stream) you created must be closed. File.Create return the filestream to the just created file.:

string filePath = "filepath here";
if (!System.IO.File.Exists(filePath))
{
    System.IO.FileStream f = System.IO.File.Create(filePath);
    f.Close();
}
using (System.IO.StreamWriter sw = System.IO.File.AppendText(filePath))
{ 
    //write my text 
}

Lets understand it with the following simple example. This happens because this is NON-STATIC INNER CLASS. You should need the instance of outer class.

 public class PQ {

    public static void main(String[] args) {

        // create dog object here
        Dog dog = new PQ().new Dog();
        //OR
        PQ pq = new PQ();
        Dog dog1 = pq.new Dog();
    }

    abstract class Animal {
        abstract void checkup();
    }

    class Dog extends Animal {
        @Override
        void checkup() {
            System.out.println("Dog checkup");

        }
    }

    class Cat extends Animal {
        @Override
        void checkup() {
            System.out.println("Cat Checkup");

        }
    }
}

If you're trying to do this via the command line...

If you're trying to run the CREATE TABLE statement from the command line interface, you need to specify the database you're working in before executing the query:

USE your_database;

Here's the documentation.

If you're trying to do this via MySQL Workbench...

...you need to select the appropriate database/catalog in the drop down menu found above the :Object Browser: tab. You can specify the default schema/database/catalog for the connection - click the "Manage Connections" options under the SQL Development heading of the Workbench splash screen.

Addendum

This all assumes there's a database you want to create the table inside of - if not, you need to create the database before anything else:

CREATE DATABASE your_database;

As a side note, consider passing strings in setWord() as const references to avoid excess copying. Also, in displayWord, consider making this a const function to follow const-correctness.

void setWord(const std::string& word) {
  theWord = word;
}

If you are reencoding in your ffmpeg command line, that may be the reason why it is CPU intensive. You need to simply copy the streams to the single container. Since I do not have your command line I cannot suggest a specific improvement here. Your acodec and vcodec should be set to copy is all I can say.

EDIT: On seeing your command line and given you have already tried it, this is for the benefit of others who come across the same question. The command:

ffmpeg -i rtsp://@192.168.241.1:62156 -acodec copy -vcodec copy c:/abc.mp4

will not do transcoding and dump the file for you in an mp4. Of course this is assuming the streamed contents are compatible with an mp4 (which in all probability they are).

With MooTools:

};

It is the same as super in Java, except it allows calling implementations from different bases when you have multiple inheritance.

class Foo {
public:
    virtual void foo() {
        ...
    }
};

class Baz {
public:
    virtual void foo() {
        ...
    }
};

class Bar : public Foo, public Baz {
public:
    virtual void foo() {
        // Choose one, or even call both if you need to.
        Foo::foo();
        Baz::foo();
    }
};

I'd suggest try the change event? test to see if it has a value if it does then you can continue with your code. jQuery has

.bind("change", function(){ ... });

Or

.change(function(){ ... }); 

which are equivalents.

http://api.jquery.com/change/

for a unique selector change your name attribute to id and then jQuery("#imafile") or a general jQuery('input[type="file"]') for all the file inputs

Here is an example of an easy and simple way to create a Hashmap from a JSON string by only using the JSON simple library:

{"Collection":{"Item_Type":"Any","Name":"A","Item_ID":"000014"},"Object_Name":"System"}

import java.io.FileReader;
import java.util.HashMap;
import java.util.Iterator; 
import java.util.Map;  
import org.json.simple.JSONObject; 
import org.json.simple.parser.*;

public class JSONRead {

public static void main(String[] args) throws Exception {
    
    Object obj = new JSONParser().parse(new FileReader("D:\\other.json"));
    
    HashMap<String,String> map =new HashMap<String,String>();
    
    // typecasting obj to JSONObject 
    JSONObject jo = (JSONObject) obj;
    
    Map Item_Id = ((Map)jo.get("Collection"));
            
    Iterator<Map.Entry> itr1 = Item_Id.entrySet().iterator(); 
    while (itr1.hasNext()) { 
        Map.Entry pair = itr1.next(); 
        String key = (String) pair.getKey();
        String value = (String) pair.getValue();
        System.out.println( pair.getKey() + " : " + pair.getValue()); 
        map.put(key, value);
    }
    
    System.out.println(map)
    System.out.println(map.get("Item"));        
}

<script type="text/javascript">
    $(document).ready(function () {
        $('#btnadd').on('click', function () {
            var n1 = parseInt($('#txtn1').val());
            var n2 = parseInt($('#txtn2').val());
            var r = n1 + n2;
            alert("sum of 2 No= " + r);
            return false;
        });
        $('#btnclear').on('click', function () {
            $('#txtn1').val('');
            $('#txtn2').val('');
            $('#txtn1').focus();
            return false;
        });
    });
</script>

You can do it in python installer:

You say you're using:

time.asctime(time.localtime(date_in_seconds_from_bash))

where date_in_seconds_from_bash is presumably the output of date +%s.

The time.localtime function, as the name implies, gives you local time.

If you want UTC, use time.gmtime() rather than time.localtime().

As JamesNoonan33's answer says, the output of date +%s is timezone invariant, so date +%s is exactly equivalent to date -u %s. It prints the number of seconds since the "epoch", which is 1970-01-01 00:00:00 UTC. The output you show in your question is entirely consistent with that:

date -u
Thu Jul 3 07:28:20 UTC 2014

date +%s
1404372514   # 14 seconds after "date -u" command

date -u +%s
1404372515   # 15 seconds after "date -u" command

You can simply use a property of the page. And the interesting thing is that you can access that property anywhere in your code.

Use this:

HttpContext.Current.User.Identity.Name

If you're using Anaconda to manage Python on your system, you can install it with:

$ conda install pyqt=4

Omit the =4 to install the most current version.

Here you have few solutions ;)

This seems to be answered - #include <fstream>.

The message means :-

incomplete type - the class has not been defined with a full class. The compiler has seen statements such as class ifstream; which allow it to understand that a class exists, but does not know how much memory the class takes up.

The forward declaration allows the compiler to make more sense of :-

void BindInput( ifstream & inputChannel ); 

It understands the class exists, and can send pointers and references through code without being able to create the class, see any data within the class, or call any methods of the class.

The has initializer seems a bit extraneous, but is saying that the incomplete object is being created.

You didn't say what's currently your .gitignore, but a .gitignore with the following contents in your root directory should do the trick.

.metadata
build

array = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

array.each { |x| puts x if x % 2 == 0 }

ruby :D

2 4 6 8 10

Using SSMS, I made sure the user had connect permissions on both the database and ReportServer.

On the specific database being queried, under properties, I mapped their credentials and enabled datareader and public permissions. Also, as others have stated-I made sure there were no denyread/denywrite boxes selected.

I did not want to enable db ownership when for their reports since they only needed to have select permissions.

you need to return when the readystate==4 e.g.

function httpGet(theUrl)
{
    if (window.XMLHttpRequest)
    {// code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp=new XMLHttpRequest();
    }
    else
    {// code for IE6, IE5
        xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange=function()
    {
        if (xmlhttp.readyState==4 && xmlhttp.status==200)
        {
            return xmlhttp.responseText;
        }
    }
    xmlhttp.open("GET", theUrl, false );
    xmlhttp.send();    
}

The adb tool can be found in sdk/platform-tools/

If you don't see this directory in your SDK, launch the SDK Manager and install "Android SDK Platform-tools"

Also update your PATH environment variable to include the platform-tools/ directory, so you can execute adb from any location.

Update django-geoposition at least to version 0.2.3 and add this to settings.py:

GEOPOSITION_GOOGLE_MAPS_API_KEY = 'YOUR_API_KEY'

You need to use background-image instead of backgroundImage. For example:

$(function() {
  $('.home').click(function() {
    $(this).css('background-image', 'url(images/tabs3.png)');
  });
}):

I clicked on this button and it worked for me.

Here is the screenshot

[tup for tup in a if tup[0] == 1]

In my case I had to do this

npm install @types/jquery --save-dev // install jquery type as dev dependency so TS can compile properly
npm install jquery --save // save jquery as a dependency

Then in the script file A.ts

import * as $ from "jquery";
... jquery code ...

Spring already provides a filter that does this job. Add following bean to your config

@Bean
public CommonsRequestLoggingFilter requestLoggingFilter() {
    CommonsRequestLoggingFilter loggingFilter = new CommonsRequestLoggingFilter();
    loggingFilter.setIncludeClientInfo(true);
    loggingFilter.setIncludeQueryString(true);
    loggingFilter.setIncludePayload(true);
    loggingFilter.setMaxPayloadLength(64000);
    return loggingFilter;
}

Don't forget to change log level of org.springframework.web.filter.CommonsRequestLoggingFilter to DEBUG.

you cannot see the groupBy data directly by print statement but you can see by iterating over the group using for loop try this code to see the group by data

group = df.groupby('A') #group variable contains groupby data
for A,A_df in group: # A is your column and A_df is group of one kind at a time
  print(A)
  print(A_df)

you will get an output after trying this as a groupby result

I hope it helps

@@ denotes a class variable, i.e. it can be inherited.

This means that if you create a subclass of that class, it will inherit the variable. So if you have a class Vehicle with the class variable @@number_of_wheels then if you create a class Car < Vehicle then it too will have the class variable @@number_of_wheels

Many of the answers here are suggesting implementing variant types using "Classical Object-Oriented Decomposition". That is, anything which might be needed on one of the variants has to be declared at the base of the hierarchy. I submit that this is a type-safe, but often very bad, approach. You either end up exposing all internal properties of all the different variants (most of which are "invalid" for each particular variant) or you end up cluttering the API of the hierarchy with tons of procedural methods (which means you have to recompile every time a new procedure is dreamed up).

I hesitate to do this, but here is a shameless plug for a blog post I wrote that outlines about 8 ways to do variant types in Java. They all suck, because Java sucks at variant types. So far the only JVM language that gets it right is Scala.

http://jazzjuice.blogspot.com/2010/10/6-things-i-hate-about-java-or-scala-is.html

The Scala creators actually wrote a paper about three of the eight ways. If I can track it down, I'll update this answer with a link.

UPDATE: found it here.

I tried all the solutions above, it fixes the issue sometimes, but still from time to time I happened to get stuck with the "Waiting for the debugger to attach" message box.

The final solution in my case was to unplug all the Android devices but the one I want to debug on. I don't know which one is the culprit: the Nexus 7 running JB 4.2, the HTC One X running ICS, the HTC Desire S running Gingerbread, or the combintation of the 3, but as soon as I only have one device plugged in, it runs smooth as silk.

        };
        multiplier = new double[][] {
                {2},
                {-1},
                {1}

        };
        System.out.println("#3\n" + toString(multiplyByMatrix(multiplicand, multiplier)));

Output:

There is another consistent way (only for IE9+) in vanilla JavaScript for this:

const iframe = document.getElementById('iframe');
const handleLoad = () => console.log('loaded');

iframe.addEventListener('load', handleLoad, true)

And if you're interested in Observables this does the trick:

return Observable.fromEventPattern(
  handler => iframe.addEventListener('load', handler, true),
  handler => iframe.removeEventListener('load', handler)
);

In the newer apache poi versions:

XSSFCellStyle style = workbook.createCellStyle();
style.setBorderTop(BorderStyle.MEDIUM);
style.setBorderBottom(BorderStyle.MEDIUM);
style.setBorderLeft(BorderStyle.MEDIUM);
style.setBorderRight(BorderStyle.MEDIUM);

if none of this answers solves you the problem, I solved it by removing the tables and creating them again automatically in this way:

when creating the backup, first backup structure and be sure of add:
DROP TABLE / VIEW / PROCEDURE / FUNCTION / EVENT
CREATE PROCEDURE / FUNCTION / EVENT
IF NOT EXISTS
AUTO_INCREMENT

then just use this backup with your db and it will remove and recreate the tables you need.

Then you backup just data, and do the same, and it will work.

You can get element count of list by following two ways:

>>> l = ['a','b','c']
>>> len(l)
3

>>> l.__len__() 
3

just do it:

$file=Get-Item "C:\temp\file.htm"
$file.Basename 
$file.Extension

The original question on this post was: How to get Keras and Tensorflow to run with an AMD GPU.

The answer to this question is as followed:

1.) Keras will work if you can make Tensorflow work correctly (optionally within your virtual/conda environment).

2.) To get Tensorflow to work on an AMD GPU, as others have stated, one way this could work is to compile Tensorflow to use OpenCl. To do so read the link below. But for brevity I will summarize the required steps here:

• You will need AMDs proprietary drivers. These are currently only available on Ubuntu 14.04 (the version before Ubuntu decided to change the way the UI is rendered). Support for Ubuntu 16.04 is at the writing of this post limited to a few GPUs through AMDProDrivers. Readers who want to do deep learning on AMD GPUs should be aware of this!

• Compiling Tensorflow with OpenCl support also requires you to obtain and install the following prerequisites: OpenCl headers, ComputeCpp.

• After the prerequisites are fulfilled, configure your build. Note that there are 3 options for compiling Tensorflow: Std Tensorflow (stable), Benoits Steiner's Tensorflow-opencl (developmental), and Luke Iwanski's Tensorflow-opencl (highly experimental) which you can pull from github. Also note that if you decide to build from any of the opencl versions, the question to use opencl will be missing because it is assumed that you are using it. Conversely, this means that if you configure from the standard tensorflow, you will need to select "Yes" when the configure script asks you to use opencl and "NO" for CUDA.

• Then run tests like so:

  $ bazel test --config=sycl -k --test_timeout 1600 -- //tensorflow/... -//tensorflow/contrib/... -//tensorflow/java/... -//tensorflow /compiler/...

Update: Doing this on my setup takes exceedingly long on my setup. The part that takes long are all the tests running. I am not sure what this means but a lot of my tests are timeing out at 1600 seconds. The duration can probably be shortened at the expense of more tests timeing out. Alternatively, you can just build tensor flow without tests. At the time of this writing, running the tests has taken 2 days already.

Or just build the pip package like so:

bazel build --local_resources 2048,.5,1.0 -c opt --config=sycl //tensorflow/tools/pip_package:build_pip_package

Please actually read the blog post over at Codeplay: Lukas Iwansky posted a comprehensive tutorial post on how to get Tensorflow to work with OpenCl just on March 30th 2017. So this is a very recent post. There are also some details which I did not write about here.

As indicated in the many posts above, little bits of information are spread throughout the interwebs. What Lukas' post adds in terms of value is that all the information was put together into one place which should make setting up Tensforflow and OpenCl a bit less daunting. I will only provide a link here:

https://www.codeplay.com/portal/03-30-17-setting-up-tensorflow-with-opencl-using-sycl

A slightly more complete walk-through has been posted here:

http://deep-beta.co.uk/setting-up-tensorflow-with-opencl-using-sycl/

It differs mainly by explicitly telling the user that he/she needs to:

• create symlinks to a subfolder
• and then actually install tensorflow via "python setup.py develop" command.

Note an alternative approach was mentioned above using tensorflow-cl:

https://github.com/hughperkins/tensorflow-cl

I am unable to discern which approach is better at this time though it appears that this approach is less active. Fewer issues are posted, and fewer conversations to resolve those issues are happening. There was a major push last year. Additional pushes have ebbed off since November 2016 although Hugh seems to have pushed some updates a few days ago as of the writing of this post. (Update: If you read some of the documentation readme, this version of tensorflowo now only relies on community support as the main developer is busy with life.)

UPDATE (2017-04-25): I have some notes based on testing tensorflow-opencl below.

• The future user of this package should note that using opencl means that all the heavy-lifting in terms of computing is shifted to the GPU. I mention this because I was personally thinking that the compute work-load would be shared between my CPU and iGPU. This means that the power of your GPU is very important (specifically, bandwidth, and available VRAM).

Following are some numbers for calculating 1 epoch using the CIFAR10 data set for MY SETUP (A10-7850 with iGPU). Your mileage will almost certainly vary!

• Tensorflow (via pip install): ~ 1700 s/epoch
• Tensorflow (w/ SSE + AVX): ~ 1100 s/epoch
• Tensorflow (w/ opencl & iGPU): ~ 5800 s/epoch

You can see that in this particular case performance is worse. I attribute this to the following factors:

• The iGPU only has 1GB. This leads to a lot of copying back and forth between CPU and GPU. (Opencl 1.2 does not have the ability to data pass via pointers yet; instead data has to be copied back and forth.)
• The iGPU only has 512 stream processors (and 32 Gb/s memory bandwidth) which in this case is slower than 4 CPUs using SSE4 + AVX instruction sets.
• The development of tensorflow-opencl is in it's beginning stages, and a lot of optimizations in SYCL etc. have not been done yet.

If you are using an AMD GPU with more VRAM and more stream processors, you are certain to get much better performance numbers. I would be interested to read what numbers people are achieving to know what's possible.

I will continue to maintain this answer if/when updates get pushed.

3.) An alternative way is currently being hinted at which is using AMD's RocM initiative, and miOpen (cuDNN equivalent) library. These are/will be open-source libraries that enable deep learning. The caveat is that RocM support currently only exists for Linux, and that miOpen has not been released to the wild yet, but Raja (AMD GPU head) has said in an AMA that using the above, it should be possible to do deep learning on AMD GPUs. In fact, support is planned for not only Tensorflow, but also Cafe2, Cafe, Torch7 and MxNet.

Update to this for using Hibernate 4.3.x / 5.0.x - you could just set this property to true:

<prop key="hibernate.jdbc.lob.non_contextual_creation">true</prop>

to get rid of that error message. Same effect but without the "threw exception" detail. See LobCreatorBuilder source for details.

you can just use

ls > filenames.txt

(usually, start a shell by using "Terminal", or "shell", or "Bash".) You may need to use cd to go to that folder first, or you can ls ~/docs > filenames.txt

Another option, using list comprehension and join:

''.join([_str[i] for i in xrange(len(_str)) if i  != 4])

I didn't realize I still had my debugger attached and was trying to build in the same Visual Studio instance. Once I stopped the debugger I was able to build.

I personnally went for:

• set wrap,
• set linebreak
• set breakindent
• set showbreak=?.

Some explanation:

• wrap option visually wraps line instead of having to scroll horizontally
• linebreak is for wrapping long lines at a specific character instead of just anywhere when the line happens to be too long, like in the middle of a word. By default, it breaks on whitespace (word separator), but you can configure it with breakat. It also does NOT insert EOL in the file as the OP wanted.
• breakat is the character where it will visually break the line. No need to modify it if you want to break at whitespace between two words.
• breakindent enables to visually indent the line when it breaks.
• showbreak enables to set the character which indicates this break.

See :h <keyword> within vim for more info.

Note that you don't need to modify textwidth nor wrapmargin if you go this route.

I faced the same error, in my case I miss-spelled ng-model directive something like "ng-moel"

Wrong one: ng-moel="user.name" Right one: ng-model="user.name"

    var l = document.getElementsByClassName("chatMessages").length;
    document.getElementsByClassName("chatMessages")[l-1].scrollIntoView();

this should work

Answer Clarification - Android Studio supports JDK8

The following is an answer to the question "What version of Java does Android support?" which is different from "What version of Java can I use to run Android Studio?" which is I believe what was actually being asked. For those looking to answer the 2nd question, you might find Using Android Studio with Java 1.7 helpful.

Also: See http://developer.android.com/sdk/index.html#latest for Android Studio system requirements. JDK8 is actually a requirement for PC and linux (as of 5/14/16).

Java 8 update (3/19/14)

Because I'd assume this question will start popping up soon with the release yesterday: As of right now, there's no set date for when Android will support Java 8.

Here's a discussion over at /androiddev - http://www.reddit.com/r/androiddev/comments/22mh0r/does_android_have_any_plans_for_java_8/

If you really want lambda support, you can checkout Retrolambda - https://github.com/evant/gradle-retrolambda. I've never used it, but it seems fairly promising.

Another Update: Android added Java 7 support

Android now supports Java 7 (minus try-with-resource feature). You can read more about the Java 7 features here: https://stackoverflow.com/a/13550632/413254. If you're using gradle, you can add the following in your build.gradle:

android {
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
}

Older response

I'm using Java 7 with Android Studio without any problems (OS X - 10.8.4). You need to make sure you drop the project language level down to 6.0 though. See the screenshot below.

What tehawtness said below makes sense, too. If they're suggesting JDK 6, it makes sense to just go with JDK 6. Either way will be fine.

Update: See this SO post -- https://stackoverflow.com/a/9567402/413254

It really depends on what is the binary itself going to do.

For example I want to create some listener.

The starting Daemon is simple task :

lis_deamon :

#!/bin/bash

# We will start the listener as Deamon process
#    
LISTENER_BIN=/tmp/deamon_test/listener
test -x $LISTENER_BIN || exit 5
PIDFILE=/tmp/deamon_test/listener.pid

case "$1" in
      start)
            echo -n "Starting Listener Deamon .... "
            startproc -f -p $PIDFILE $LISTENER_BIN
            echo "running"
            ;;
          *)
            echo "Usage: $0 start"
            exit 1
            ;;
esac

this is how we start the daemon (common way for all /etc/init.d/ staff)

now as for the listener it self, It must be some kind of loop/alert or else that will trigger the script to do what u want. For example if u want your script to sleep 10 min and wake up and ask you how you are doing u will do this with the

while true ; do sleep 600 ; echo "How are u ? " ; done

Here is the simple listener that u can do that will listen for your commands from remote machine and execute them on local :

listener :

#!/bin/bash

# Starting listener on some port
# we will run it as deamon and we will send commands to it.
#
IP=$(hostname --ip-address)
PORT=1024
FILE=/tmp/backpipe
count=0
while [ -a $FILE ] ; do #If file exis I assume that it used by other program
  FILE=$FILE.$count
  count=$(($count + 1))
done

# Now we know that such file do not exist,
# U can write down in deamon it self the remove for those files
# or in different part of program

mknod $FILE p

while true ; do 
  netcat -l -s $IP -p $PORT < $FILE |/bin/bash > $FILE
done
rm $FILE

So to start UP it : /tmp/deamon_test/listener start

and to send commands from shell (or wrap it to script) :

test_host#netcat 10.184.200.22 1024
uptime
 20:01pm  up 21 days  5:10,  44 users,  load average: 0.62, 0.61, 0.60
date
Tue Jan 28 20:02:00 IST 2014
 punt! (Cntrl+C)

Hope this will help.

The javadoc for refEq mentioned that the equality check is shallow! You can find more details at the link below:

https://static.javadoc.io/org.mockito/mockito-core/2.2.29/org/mockito/ArgumentMatchers.html#refEq(T,%20java.lang.String...)

"shallow equality" issue cannot be controlled when you use other classes which don't implement .equals() method,"DefaultMongoTypeMapper" class is an example where .equals() method is not implemented.

org.springframework.beans.factory.support offers a method that can generate a bean definition instead of creating an instance of the object, and it can be used to git rid of Comparison Failure.

 genericBeanDefinition(DefaultMongoTypeMapper.class)
                        .setScope(SCOPE_SINGLETON)
                        .setAutowireMode(AUTOWIRE_CONSTRUCTOR)
                        .setLazyInit(false)
                        .addConstructorArgValue(null)
                        .getBeanDefinition()

**"The bean definition is only a description of the bean, not a bean itself. the bean descriptions properly implement equals() and hashCode(), so rather than creating a new DefaultMongoTypeMapper() we provide a definition that tells spring how it should create one"

In your example, you can do somethong like this

Mockito.verify(mockedObject)
       .doSoething(genericBeanDefinition(YourClass.class).setA("a")
       .getBeanDefinition());

Rahul's answer gives me an error: You seem to be trying to send a WhatsApp message to a phone number that is not registered with WhatsApp..., even though I'm sending it to a registered WhatsApp number.

This, however works:

<li><a href="intent:0123456789#Intent;scheme=smsto;package=com.whatsapp;action=android.intent.action.SENDTO;end"><i class="fa fa-whatsapp"></i>+237 655 421 621</li>

You can use casting:

<?php

$string = "<element><child>Hello World</child></element>";
$xml = new SimpleXMLElement($string);

$text = (string)$xml->child;

$text will be 'Hello World'

How about

Have a reference of stream form successHandle

var streamRef;

var handleVideo = function (stream) {
    streamRef = stream;
}

//this will stop video and audio both track
streamRef.getTracks().map(function (val) {
    val.stop();
});

This happened to me and while sourcetree kept telling me the lock file exists, there was no such a file there for me to remove. So I just checked out another branch and then returned to the original branch and noticed this change fixed the issue.

If we don't think this is a bug the team should fix, at lease MSDN should improve the document. The confusing really comes from the poor document of this. In MSDN, it explains the parameters name as,

Type: System.String
The name of the form field to return.

This just means the final html it generates will use that parameter as the name of the select input. But, it actually means more than that.

I guess the designer assumes that user will use a view model to display the dropdownlist, also will use post back to the same view model. But in a lot cases, we don't really follow that assumption.

Use the example above,

public class Person {
    public int Id { get; set; }
    public string Name { get; set; }
}

If we follow the assumption,we should define a view model for this dropdownlist related view

public class PersonsSelectViewModel{
    public string SelectedPersonId,
    public List<SelectListItem> Persons;
}

Because when post back, only the selected value will post back, so it assume it should post back to the model's property SelectedPersonId, which means Html.DropDownList's first parameter name should be 'SelectedPersonId'. So, the designer thinks that when display the model view in the view, the model's property SelectedPersonId should hold the default value of that dropdown list. Even thought your List<SelectListItem> Persons already set the Selected flag to indicate which one is selected/default, the tml.DropDownList will actually ignore that and rebuild it's own IEnumerable<SelectListItem> and set the default/selected item based on the name.

Here is the code from asp.net mvc

private static MvcHtmlString SelectInternal(this HtmlHelper htmlHelper, ModelMetadata metadata,
            string optionLabel, string name, IEnumerable<SelectListItem> selectList, bool allowMultiple,
            IDictionary<string, object> htmlAttributes)
{
    ...

    bool usedViewData = false;

    // If we got a null selectList, try to use ViewData to get the list of items.
    if (selectList == null)
    {
        selectList = htmlHelper.GetSelectData(name);
        usedViewData = true;
    }

    object defaultValue = (allowMultiple) ? htmlHelper.GetModelStateValue(fullName, typeof(string[])) : htmlHelper.GetModelStateValue(fullName, typeof(string));

    // If we haven't already used ViewData to get the entire list of items then we need to
    // use the ViewData-supplied value before using the parameter-supplied value.
    if (defaultValue == null && !String.IsNullOrEmpty(name))
    {
        if (!usedViewData)
        {
            defaultValue = htmlHelper.ViewData.Eval(name);
        }
        else if (metadata != null)
        {
            defaultValue = metadata.Model;
        }
    }

    if (defaultValue != null)
    {
        selectList = GetSelectListWithDefaultValue(selectList, defaultValue, allowMultiple);
    }

    ...

    return tagBuilder.ToMvcHtmlString(TagRenderMode.Normal);
}

So, the code actually went further, it not only try to look up the name in the model, but also in the viewdata, as soon as it finds one, it will rebuild the selectList and ignore your original Selected.

The problem is, in a lot of cases, we don't really use it that way. we just want to throw in a selectList with one/multiple item(s) Selected set true.

Of course the solution is simple, use a name that not in the model nor in the viewdata. When it can not find a match, it will use the original selectList and the original Selected will take affect.

But i still think mvc should improve it by add one more condition

if ((defaultValue != null) && (!selectList.Any(i=>i.Selected)))
{
    selectList = GetSelectListWithDefaultValue(selectList, defaultValue, allowMultiple);
}

Because, if the original selectList has already had one Selected, why would you ignore that?

Just my thoughts.

A simple parameter class can be used to pass multiple parameters in a post:

public class AddCustomerArgs
{
    public string First { get; set; }
    public string Last { get; set; }
}

[HttpPost]
public IHttpActionResult AddCustomer(AddCustomerArgs args)
{
    //use args...
    return Ok();
}

The solution to the problem for me was found in the XML document for my Main Activity. Originally my toolbar was <android.support.v7.widget.Toolbar. To resolve this I changed it to <android.widget.Toolbar. I do not know why this worked though. Does anyone have any insight as to why?

If the HTTP Connection doesn't timeout, You can implement the timeout checker in the background thread itself (AsyncTask, Service, etc), the following class is an example for Customize AsyncTask which timeout after certain period

public abstract class AsyncTaskWithTimer<Params, Progress, Result> extends
    AsyncTask<Params, Progress, Result> {

private static final int HTTP_REQUEST_TIMEOUT = 30000;

@Override
protected Result doInBackground(Params... params) {
    createTimeoutListener();
    return doInBackgroundImpl(params);
}

private void createTimeoutListener() {
    Thread timeout = new Thread() {
        public void run() {
            Looper.prepare();

            final Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {

                    if (AsyncTaskWithTimer.this != null
                            && AsyncTaskWithTimer.this.getStatus() != Status.FINISHED)
                        AsyncTaskWithTimer.this.cancel(true);
                    handler.removeCallbacks(this);
                    Looper.myLooper().quit();
                }
            }, HTTP_REQUEST_TIMEOUT);

            Looper.loop();
        }
    };
    timeout.start();
}

abstract protected Result doInBackgroundImpl(Params... params);
}

A Sample for this

public class AsyncTaskWithTimerSample extends AsyncTaskWithTimer<Void, Void, Void> {

    @Override
    protected void onCancelled(Void void) {
        Log.d(TAG, "Async Task onCancelled With Result");
        super.onCancelled(result);
    }

    @Override
    protected void onCancelled() {
        Log.d(TAG, "Async Task onCancelled");
        super.onCancelled();
    }

    @Override
    protected Void doInBackgroundImpl(Void... params) {
        // Do background work
        return null;
    };
 }

I think the node server is running from another folder. So kill it and run in the current folder.

Find running node server:-

lsof -i :8081

Kill running node server :-

kill -9 <PID>

Eg:-

kill -9 1653

Start node server from current react native folder:-

react-native run-android

$1, $2, etc will contain the value of captures from the last successful match - it's important to check whether the match succeeded before accessing them, i.e.

 if ( $var =~ m/( )/ ) { # use $1 etc... }

An example of the problem - $1 contains 'Quick' in both print statements below:

#!/usr/bin/perl

'Quick brown fox' =~ m{ ( quick ) }ix;
print "Found: $1\n";

'Lazy dog' =~ m{ ( quick ) }ix;
print "Found: $1\n";

Great question, great answers. Here's a quick way to echo the results if anyone is reading this page and missing that part:

$counter = mysql_query("SELECT COUNT(*) AS id FROM table");
$num = mysql_fetch_array($counter);
$count = $num["id"];
echo("$count");

This should work without converting to List/Array:

collectionName.stream().reduce((prev, next) -> next).orElse(null)

I had this problem a while back and the solution was really easy.

Just uninstall the current version of Java, download an older one, then uninstall the older and install the latest again.

For example: Java 8 Update 73 current install Java 7 Update 95.

How it works: Java's registry keys were messed up, and when you install the older version they get fixed.

If you haven't actually registered any users with your existing format then you would be best to switch to using the BCrypt password encoder instead.

It's a lot less hassle, as you don't have to worry about salt at all - the details are completely encapsulated within the encoder. Using BCrypt is stronger than using a plain hash algorithm and it's also a standard which is compatible with applications using other languages.

There's really no reason to choose any of the other options for a new application.

You can use reflect.DeepEqual, or you can implement your own function (which performance wise would be better than using reflection):

http://play.golang.org/p/CPdfsYGNy_

m1 := map[string]int{   
    "a":1,
    "b":2,
}
m2 := map[string]int{   
    "a":1,
    "b":2,
}
fmt.Println(reflect.DeepEqual(m1, m2))

The following script is tested and gives exactly the results, that are expected

\#!/bin/bash

echo "Enter the file name"

read file

echo "enter the word to be found"

read word

count=0

for i in \`cat $file`

do

if [ $i == $word ]

then

count=\`expr $count + 1`

fi

done

echo "The number of words are $count"

In my case, I had to call an API repeatedly in a loop, which resulted in halt of my system returning a 403 Forbidden Error. Since my API provider does not allow multiple requests from the same client within milliseconds, I had to use a delay of 1 second at least :

foreach (var it in list)
{
    Thread.Sleep(1000);
    // Call API
}

It is an old question but thought to leave this here. Most people are checking if the variable is {} meaning a key-value paired and not what is the underline construct that JavaScript is using for a given thing, cuz to be honest mostly everything in JavaScript is an object. So taking that out of the way. If you do...

let x = function() {}
typeof x === 'function' //true
x === Object(x) // true
x = []
x === Object(x) // true

// also
x = null
typeof null // 'object'

Most of the time what we want is to know if we have a resource object from an API or our database call returned from the ORM. We can then test if is not an Array, is not null, is not typeof 'function', and is an Object

// To account also for new Date() as @toddmo pointed out

x instanceof Object && x.constructor === Object

x = 'test' // false
x = 3 // false
x = 45.6 // false
x = undefiend // false
x = 'undefiend' // false
x = null // false
x = function(){} // false
x = [1, 2] // false
x = new Date() // false
x = {} // true

Properties prop = new Properties();
String fileName = "./src/test/resources/predefined.properties";
FileInputStream inputStream = new FileInputStream(fileName);
InputStreamReader reader = new InputStreamReader(inputStream,"UTF-8");

You should iterate over the keys and get the values using square brackets.

See: How do I enumerate the properties of a javascript object?

EDIT: Obviously, this makes the question a duplicate.

In case anyone still has to support legacy fancybox with jQuery 3.0+ here are some other changes you'll have to make:

.unbind() deprecated

Replace all instances of .unbind with .off

.removeAttribute() is not a function

Change lines 580-581 to use jQuery's .removeAttr() instead:

Old code:

580: content[0].style.removeAttribute('filter');
581: wrap[0].style.removeAttribute('filter');

New code:

580: content.removeAttr('filter');
581: wrap.removeAttr('filter');

This combined with the other patch mentioned above solved my compatibility issues.

To simplify leed25d's answer, use a combination of an alias and a function. For example:

function __GetIt {
    cp ./path/to/stuff/$* .
}

alias GetIt='__GetIt'

With Java 1.8 there is a new StringJoiner class - so no need for Guava or Apache Commons:

String str = new StringJoiner(",").add("a").add("b").add("c").toString();

Or using a collection directly with the new stream api:

String str = Arrays.asList("a", "b", "c").stream().collect(Collectors.joining(","));

Your statement matches any string that contains a letter or digit anywhere, even if it contains other non-alphanumeric characters. Try this:

SELECT * FROM table WHERE column REGEXP '^[A-Za-z0-9]+$';

^ and $ require the entire string to match rather than just any portion of it, and + looks for 1 or more alphanumberic characters.

You could also use a named character class if you prefer:

SELECT * FROM table WHERE column REGEXP '^[[:alnum:]]+$';

You can use useEffect/useLayoutEffect to achieve this:

const SomeComponent = () => {
  const [count, setCount] = React.useState(0)

  React.useEffect(() => {
    if (count > 1) {
      document.title = 'Threshold of over 1 reached.';
    } else {
      document.title = 'No threshold reached.';
    }
  }, [count]);

  return (
    <div>
      <p>{count}</p>

      <button type="button" onClick={() => setCount(count + 1)}>
        Increase
      </button>
    </div>
  );
};

More about it over here.

If you are looking for an out of the box solution, check out this custom hook that works like useState but accepts as second parameter a callback function:

// npm install use-state-with-callback

import useStateWithCallback from 'use-state-with-callback';

const SomeOtherComponent = () => {
  const [count, setCount] = useStateWithCallback(0, count => {
    if (count > 1) {
      document.title = 'Threshold of over 1 reached.';
    } else {
      document.title = 'No threshold reached.';
    }
  });

  return (
    <div>
      <p>{count}</p>

      <button type="button" onClick={() => setCount(count + 1)}>
        Increase
      </button>
    </div>
  );
};

import os
os.listdir("path") # returns list

put public, protected or private before the $connection.

ArrayList has a indexOf() method. Check the API for more, but here's how it works:

private ArrayList<String> _categories; // Initialize all this stuff

private int getCategoryPos(String category) {
  return _categories.indexOf(category);
}

indexOf() will return exactly what your method returns, fast.

Use chown to change ownership and chmod to change rights.

use the -R option to apply the rights for all files inside of a directory too.

Note that both these commands just work for directories too. The -R option makes them also change the permissions for all files and directories inside of the directory.

For example

sudo chown -R username:group directory

will change ownership (both user and group) of all files and directories inside of directory and directory itself.

sudo chown username:group directory

will only change the permission of the folder directory but will leave the files and folders inside the directory alone.

you need to use sudo to change the ownership from root to yourself.

Edit:

Note that if you use chown user: file (Note the left-out group), it will use the default group for that user.

Also You can change the group ownership of a file or directory with the command:

chgrp group_name file/directory_name

You must be a member of the group to which you are changing ownership to.

You can find group of file as follows

# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file

# chown sujit:friends file

User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.

What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.

But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.

Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.

System Preferences => Keyboard => Key Repeat Rate

In my firefox and chrome work this:

CSS:

display: flex;
justify-content: center;     // vertical align
align-items: center;         // horizontal align

You can use values() method:

For instance Status.values()[0] will return PAUSE in your case, if you print it, toString() will be called and "PAUSE" will be printed.

In your manifest use:-

    android:theme="@style/AppTheme" >

in styles.xml:-

<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
       <item name="android:windowActionBar">false</item>
   <item name="android:windowNoTitle">true</item>
</style>

Surprisingly this works as yo desire, Using the same parent of AppBaseTheme in AppTheme does not.

just remove this because constructor don't have a return type like void it will be like this :

private Flow()
    {
        X = x;
        Y = y;
    }  

def nans(df): return df[df.isnull().any(axis=1)]

then when ever you need it you can type:

nans(your_dataframe)

For Windows you can check it using PowerShell

$PathInvalidChars = [System.IO.Path]::GetInvalidPathChars() #36 chars

To display UTF-8 codes you can convert

$enc = [system.Text.Encoding]::UTF8
$PathInvalidChars | foreach { $enc.GetBytes($_) }

$FileNameInvalidChars = [System.IO.Path]::GetInvalidFileNameChars() #41 chars

$FileOnlyInvalidChars = @(':', '*', '?', '\', '/') #5 chars - as a difference

This problem can be easily solved by using view models. View models are classes that are specifically tailored to the needs of a given view. So for example in your case you could have the following view models:

public UpdateViewView
{
    [Required]
    public string Id { get; set; }

    ... some other properties
}

public class InsertViewModel
{
    public string Id { get; set; }

    ... some other properties
}

which will be used in their corresponding controller actions:

[HttpPost]
public ActionResult Update(UpdateViewView model)
{
    ...
}

[HttpPost]
public ActionResult Insert(InsertViewModel model)
{
    ...
}

Suspend the process with CTRL+Z then use the command bg to resume it in background. For example:

sleep 60
^Z  #Suspend character shown after hitting CTRL+Z
[1]+  Stopped  sleep 60  #Message showing stopped process info
bg  #Resume current job (last job stopped)

More about job control and bg usage in bash manual page:

JOB CONTROL
Typing the suspend character (typically ^Z, Control-Z) while a process is running causes that process to be stopped and returns control to bash. [...] The user may then manipulate the state of this job, using the bg command to continue it in the background, [...]. A ^Z takes effect immediately, and has the additional side effect of causing pending output and typeahead to be discarded.

bg [jobspec ...]
Resume each suspended job jobspec in the background, as if it had been started with &. If jobspec is not present, the shell's notion of the current job is used.

EDIT

To start a process where you can even kill the terminal and it still carries on running

nohup [command] [-args] > [filename] 2>&1 &

e.g.

nohup /home/edheal/myprog -arg1 -arg2 > /home/edheal/output.txt 2>&1 &

To just ignore the output (not very wise) change the filename to /dev/null

To get the error message set to a different file change the &1 to a filename.

In addition: You can use the jobs command to see an indexed list of those backgrounded processes. And you can kill a backgrounded process by running kill %1 or kill %2 with the number being the index of the process.

In my particular case it was easier to do this:

 panel.setOpaque(true);
 panel.setBackground(new Color(0,0,0,0,)): // any color with alpha 0 (in this case the color is black

I had the same error, the problem was because I no longer had disk space. to check the space run this:

$ df -h

Then delete some files that you didn't need.

After this commands:

service mysql start
systemctl status mysql.service
mysql -u root -p

After entering with the root password verify that the mysql service was active

You can store the array using serialize/unserialize. With that solution they cannot easily be used from other programming languages, so you may consider using json_encode/json_decode instead (which gives you a widely supported format). Avoid using implode/explode for this since you'll probably end up with bugs or security flaws.

Note that this makes your table non-normalized, which may be a bad idea since you cannot easily query the data. Therefore consider this carefully before going forward. May you need to query the data for statistics or otherwise? Are there other reasons to normalize the data?

Also, don't save the raw $_POST array. Someone can easily make their own web form and post data to your site, thereby sending a really large form which takes up lots of space. Save those fields you want and make sure to validate the data before saving it (so you won't get invalid values).

Because you imported scipy, not sparse. Try from scipy import sparse?

Default argument values are evaluated at function define-time, but self is an argument only available at function call time. Thus arguments in the argument list cannot refer each other.

It's a common pattern to default an argument to None and add a test for that in code:

def p(self, b=None):
    if b is None:
        b = self.a
    print b

"A comment for a column can be specified with the COMMENT option. The comment is displayed by the SHOW CREATE TABLE and SHOW FULL COLUMNS statements. This option is operational as of MySQL 4.1. (It is allowed but ignored in earlier versions.)"

As an example

--
-- Table structure for table 'accesslog'
--

CREATE TABLE accesslog (
aid int(10) NOT NULL auto_increment COMMENT 'unique ID for each access entry', 
title varchar(255) default NULL COMMENT 'the title of the page being accessed',
path varchar(255) default NULL COMMENT 'the local path of teh page being accessed',
....
) TYPE=MyISAM;

If you want to modify the original array instead of returning a new array, use .push()...

array1.push.apply(array1, array2);
array1.push.apply(array1, array3);

I used .apply to push the individual members of arrays 2 and 3 at once.

or...

array1.push.apply(array1, array2.concat(array3));

To deal with large arrays, you can do this in batches.

for (var n = 0, to_add = array2.concat(array3); n < to_add.length; n+=300) {
    array1.push.apply(array1, to_add.slice(n, n+300));
}

If you do this a lot, create a method or function to handle it.

var push_apply = Function.apply.bind([].push);
var slice_call = Function.call.bind([].slice);

Object.defineProperty(Array.prototype, "pushArrayMembers", {
    value: function() {
        for (var i = 0; i < arguments.length; i++) {
            var to_add = arguments[i];
            for (var n = 0; n < to_add.length; n+=300) {
                push_apply(this, slice_call(to_add, n, n+300));
            }
        }
    }
});

and use it like this:

array1.pushArrayMembers(array2, array3);

var push_apply = Function.apply.bind([].push);_x000D_
var slice_call = Function.call.bind([].slice);_x000D_
_x000D_
Object.defineProperty(Array.prototype, "pushArrayMembers", {_x000D_
    value: function() {_x000D_
        for (var i = 0; i < arguments.length; i++) {_x000D_
            var to_add = arguments[i];_x000D_
            for (var n = 0; n < to_add.length; n+=300) {_x000D_
                push_apply(this, slice_call(to_add, n, n+300));_x000D_
            }_x000D_
        }_x000D_
    }_x000D_
});_x000D_
_x000D_
var array1 = ['a','b','c'];_x000D_
var array2 = ['d','e','f'];_x000D_
var array3 = ['g','h','i'];_x000D_
_x000D_
array1.pushArrayMembers(array2, array3);_x000D_

The performance improvement that triggered this regression has been reverted from from trunk, 8.0.x (for 8.0.16 onwards) and 7.0.x (for 7.0.58 onwards) and will not be reapplied.

In Swift 4.2 and Xcode 10.1

In Swift strings can be treated like an array of individual characters. So each character in string is like an element in array. To get the length of a string use yourStringName.count property.

In Swift

yourStringName.characters.count property in deprecated. So directly use strLength.count property.

let strLength = "This is my string"
print(strLength.count)
//print(strLength.characters.count) //Error: 'characters' is deprecated: Please use String or Substring directly

If Objective C

NSString *myString = @"Hello World";
NSLog(@"%lu", [myString length]); // 11

Enable Internet Sharing using USB ports:

The non-recursive version of the function is not too hard - here it is for integers:

long powi(long x, unsigned n)
{
    long p = x;
    long r = 1;

    while (n > 0)
    {
        if (n % 2 == 1)
            r *= p;
        p *= p;
        n /= 2;
    }

    return(r);
}

(Hacked out of code for raising a double value to an integer power - had to remove the code to deal with reciprocals, for example.)

The whole point of HttpOnly cookies is that they can't be accessed by JavaScript.

The only way (except for exploiting browser bugs) for your script to read them is to have a cooperating script on the server that will read the cookie value and echo it back as part of the response content. But if you can and would do that, why use HttpOnly cookies in the first place?

You can either give class name to all label so that all can have same width :

 .class-name {  width:200px;}

Example

.labelname{  width:200px;}

or you can simple give rest of label

label {  width:200px;  display: inline-block;}

Two things you can check is,

class Slider extends React.Component {
    // Your React Code
}

Slider.propTypes = {
    // accessibility: PropTypes.bool,
}

• Make sure that you extends React.Component
• Use propTypes instead of prototype (as per IDE intellisense)

This XML file does not appear to have any style information associated with it. The document tree is shown below.

You will get this error in the client side when the client (the webbrowser) for some reason interprets the HTTP response content as text/xml instead of text/html and the parsed XML tree doesn't have any XML-stylesheet. In other words, the webbrowser incorrectly parsed the retrieved HTTP response content as XML instead of as HTML due to the wrong or missing HTTP response content type.

In case of JSF/Facelets files which have the default extension of .xhtml, that can in turn happen if the HTTP request hasn't invoked the FacesServlet and thus it wasn't able to parse the Facelets file and generate the desired HTML output based on the XHTML source code. Firefox is then merely guessing the HTTP response content type based on the .xhtml file extension which is in your Firefox configuration apparently by default interpreted as text/xml.

You need to make sure that the HTTP request URL, as you see in browser's address bar, matches the <url-pattern> of the FacesServlet as registered in webapp's web.xml, so that it will be invoked and be able to generate the desired HTML output based on the XHTML source code. If it's for example *.jsf, then you need to open the page by /some.jsf instead of /some.xhtml. Alternatively, you can also just change the <url-pattern> to *.xhtml. This way you never need to fiddle with virtual URLs.

See also:

• JSF Facelets: Sometimes I see the URL is .jsf and sometimes .xhtml. Why?

Note thus that you don't actually need a XML stylesheet. This all was just misinterpretation by the webbrowser while trying to do its best to make something presentable out of the retrieved HTTP response content. It should actually have retrieved the properly generated HTML output, Firefox surely knows precisely how to deal with HTML content.

Careful when doing a Find Loop that you don't get yourself into an infinite loop... Reference the first found cell address and compare after each "FindNext" statement to make sure it hasn't returned back to the first initially found cell.

Python 2.6+

next(iter(your_list), None)

If your_list can be None:

next(iter(your_list or []), None)

Python 2.4

def get_first(iterable, default=None):
    if iterable:
        for item in iterable:
            return item
    return default

Example:

x = get_first(get_first_list())
if x:
    ...
y = get_first(get_second_list())
if y:
    ...

Another option is to inline the above function:

for x in get_first_list() or []:
    # process x
    break # process at most one item
for y in get_second_list() or []:
    # process y
    break

To avoid break you could write:

for x in yield_first(get_first_list()):
    x # process x
for y in yield_first(get_second_list()):
    y # process y

Where:

def yield_first(iterable):
    for item in iterable or []:
        yield item
        return

As Vinay Kumar pointed out that it will not update global installed Angular CLI. To update it globally just use following commands:

npm uninstall -g @angular/cli
npm cache clean
npm install -g @angular/cli@latest

Note if you want to update existing project you have to modify existing project, you should change package.json inside your project.

There are no breaking changes in Angular itself but they are in RxJS, so don't forget to use rxjs-compat library to work with legacy code.

  npm install --save rxjs-compat  

I wrote a good article about installation/updating Angular CLI http://bmnteam.com/angular-cli-installation/

The traditional method is to use a table.

Example:

<table>
  <tbody>
     <tr>
        <td>
           First Name:
        </td>
        <td>
           <input type="text" name="first">
        </td>
     </tr>
     <tr>
        <td>
           Last Name:
        </td>
        <td>
           <input type="text" name="last">
        </td>
     </tr>

However, many would argue that tables are restricting and prefer CSS. The benefit of using CSS is that you could use various elements. From divs, ordered and un-ordered list, you could accomplish the same layout.

In the end, you'll want to use what you're most comfortable with.

Hint: Tables are easy to get started with.

You can use this js code. Just change .post-thumb img with your img.

$('.post-thumb img').each(function(){           // Note: {.post-thumb img} is css selector of the image tag
    var t = $(this),
        s = 'url(' + t.attr('src') + ')',
        p = t.parent(),
        d = $('<div></div>');
    t.hide();
    p.append(d);
    d.css({
        'height'                : 260,          // Note: You can change it for your needs
        'background-size'       : 'cover',
        'background-repeat'     : 'no-repeat',
        'background-position'   : 'center',
        'background-image'      : s
    });
});

Some more alternative options because regexes (regi ?) are awesome!

Here is a Simple regex to do the job:

 regex="[^/]*$"

Example (grep):

 FP="/hello/world/my/file/path/hello_my_filename.log"
 echo $FP | grep -oP "$regex"
 #Or using standard input
 grep -oP "$regex" <<< $FP

Example (awk):

 echo $FP | awk '{match($1, "$regex",a)}END{print a[0]}
 #Or using stardard input
 awk '{match($1, "$regex",a)}END{print a[0]} <<< $FP

If you need a more complicated regex: For example your path is wrapped in a string.

 StrFP="my string is awesome file: /hello/world/my/file/path/hello_my_filename.log sweet path bro."

 #this regex matches a string not containing / and ends with a period 
 #then at least one word character 
 #so its useful if you have an extension

 regex="[^/]*\.\w{1,}"

 #usage
 grep -oP "$regex" <<< $StrFP

 #alternatively you can get a little more complicated and use lookarounds
 #this regex matches a part of a string that starts with /  that does not contain a / 
 ##then uses the lazy operator ? to match any character at any amount (as little as possible hence the lazy)
 ##that is followed by a space
 ##this allows use to match just a file name in a string with a file path if it has an exntension or not
 ##also if the path doesnt have file it will match the last directory in the file path 
 ##however this will break if the file path has a space in it.

 regex="(?<=/)[^/]*?(?=\s)"

 #to fix the above problem you can use sed to remove spaces from the file path only
 ## as a side note unfortunately sed has limited regex capibility and it must be written out in long hand.
 NewStrFP=$(echo $StrFP | sed 's:\(/[a-z]*\)\( \)\([a-z]*/\):\1\3:g')
 grep -oP "$regex" <<< $NewStrFP

Total solution with Regexes:

This function can give you the filename with or without extension of a linux filepath even if the filename has multiple "."s in it. It can also handle spaces in the filepath and if the file path is embedded or wrapped in a string.

#you may notice that the sed replace has gotten really crazy looking
#I just added all of the allowed characters in a linux file path
function Get-FileName(){
    local FileString="$1"
    local NoExtension="$2"
    local FileString=$(echo $FileString | sed 's:\(/[a-zA-Z0-9\<\>\|\\\:\)\(\&\;\,\?\*]*\)\( \)\([a-zA-Z0-9\<\>\|\\\:\)\(\&\;\,\?\*]*/\):\1\3:g')

    local regex="(?<=/)[^/]*?(?=\s)"

    local FileName=$(echo $FileString | grep -oP "$regex")

    if [[ "$NoExtension" != "" ]]; then
        sed 's:\.[^\.]*$::g' <<< $FileName
    else
        echo "$FileName"
    fi
}

## call the function with extension
Get-FileName "my string is awesome file: /hel lo/world/my/file test/path/hello_my_filename.log sweet path bro."

##call function without extension
Get-FileName "my string is awesome file: /hel lo/world/my/file test/path/hello_my_filename.log sweet path bro." "1"

If you have to mess with a windows path you can start with this one:

 [^\\]*$       

In Android Studio, Gradle is used for building our android application projects, hence playing the role of a build system. Before Android Studio, in Eclipse we used to compile and build the applications using command line tool which was soon taken over by GUI based steps to build and run Android Applications in eclipse using ANT. Every android application development tool has to compile resources, java source code, external libraries and combine them into a final APK.

Gradle is a build system, which is responsible for code compilation, testing, deployment and conversion of the code into .dex files and hence running the app on the device.

As Android Studio comes with Gradle system pre-installed, there is no need to install additional runtime softwares to build our project. Whenever you click on button in android studio, a gradle task automatically triggers and starts building the project and after gradle completes its task, app starts running in AVD or in the connected device.

A build system like Gradle is not a compiler, linker etc, but it controls and supervises the operation of compilation, linking of files, running test cases, and eventually bundling the code into an apk file for your Android Application.

There are two build.gradle files for every android studio project of which, one is for application and other is for project level(module level) build files.

In the build process, the compiler takes the source code, resources, external libraries JAR files and AndroidManifest.xml(which contains the meta-data about the application) and convert them into .dex(Dalvik Executable files) files, which includes bytecode. That bytecode is supported by all android devices to run your app. Then APK Manager combines the .dex files and all other resources into single apk file. APK Packager signs debug or release apk using respective debug or release keystore.

Debug apk is generally used for testing purpose or we can say that it is used at development stage only. When your app is complete with desired features and you are ready to publish your application for external use then you require a Release apk signed using a release keystore.

Now lets shed some light on the gradle files.

setting.gradle The setting.gradle(Gradle setting) file is used to specify all the modules used in your app.

build.gradle (project level) The Top level (module) build.gradle file is project level build file, which defines build configurations at project level. This file applies configurations to all the modules in android application project.

build.gradle (application level) The Application level build.gradle file is located in each module of the android project. This file includes your package name as applicationID, version name(apk version), version code, minimum and target sdk for a specific application module. When you are including external libraries(not the jar files) then you need to mention it in the app level gradle file to include them in your project as dependencies of the application.

Note: If a certain application is developed in variations for individual modules like, Smart Phone, Tablet or TV then separate gradle files must to be created for all. You can even start your gradle system through command line tool. Following commands are used for it:

./gradlew build - (build project)
./gradlew clean build - (build project complete scratch)
./gradlew clean build - (run the test)
./gradlew wrapper - (to see all the available tasks)

var.connectionstring = "server=localhost; database=dbname; integrated security=yes"

or

var.connectionstring = "server=localhost; database=dbname; login=yourlogin; pwd=yourpass"

You can use styles for modifiy the login button like this

<style name="FacebookLoginButton">
    <item name="android:textSize">@dimen/smallTxtSize</item>
    <item name="android:background">@drawable/facebook_signin_btn</item>
    <item name="android:layout_marginTop">10dp</item>
    <item name="android:layout_marginBottom">10dp</item>
    <item name="android:layout_gravity">center_horizontal</item>
</style>

and in layout

<com.facebook.widget.LoginButton
        xmlns:fb="http://schemas.android.com/apk/res-auto"
        android:id="@+id/loginFacebookButton"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        fb:login_text="@string/loginFacebookButton"
        fb:logout_text=""
        style="@style/FacebookLoginButton"/>

Why not just select the Table and view the variable that way?

SELECT * FROM @d

The correct answer is usually to use require, but in a few cases it's not possible.

The following code will do the trick, but use it with care:

var fs = require('fs');
var vm = require('vm');
var includeInThisContext = function(path) {
    var code = fs.readFileSync(path);
    vm.runInThisContext(code, path);
}.bind(this);
includeInThisContext(__dirname+"/models/car.js");

patterns[1]="1\.2\.3\.4.*Has exploded"
patterns[2]="5\.6\.7\.8.*Has died"
patterns[3]="\!9\.10\.11\.12.*Has exploded"

for i in {1..3}
 do
grep "${patterns[$i]}" logfile.log
done

should be the the same as

egrep "(1\.2\.3\.4.*Has exploded|5\.6\.7\.8.*Has died)" logfile.log | egrep -v "9\.10\.11\.12.*Has exploded"    

Important difference between setting Classpath in Windows and Linux is path separator which is ";" (semi-colon) in Windows and ":" (colon) in Linux. Also %PATH% is used to represent value of existing path variable in Windows while ${PATH} is used for same purpose in Linux (in the bash shell). Here is the way to setup classpath in Linux:

export CLASSPATH=${CLASSPATH}:/new/path

but as such Classpath is very tricky and you may wonder why your program is not working even after setting correct Classpath. Things to note:

1. -cp options overrides CLASSPATH environment variable.
2. Classpath defined in Manifest file overrides both -cp and CLASSPATH envorinment variable.

Reference: How Classpath works in Java.

The other answers that involve writing a custom Collector are probably more efficient (such as Louis Wasserman's, +1), but if you want brevity, I'd suggest the following:

List<User> result = users.stream()
    .filter(user -> user.getId() == 1)
    .limit(2)
    .collect(Collectors.toList());

Then verify the size of the result list.

if (result.size() != 1) {
  throw new IllegalStateException("Expected exactly one user but got " + result);
User user = result.get(0);
}

Answers so far haven't addressed the "entire stream" part of the question. I think the good way to do this is ioutil.ReadAll. With your io.ReaderCloser named rc, I would write,

Go >= v1.16

if b, err := io.ReadAll(rc); err == nil {
    return string(b)
} ...

Go <= v1.15

if b, err := ioutil.ReadAll(rc); err == nil {
    return string(b)
} ...
