Most devices have some form of emulated storage. if they support sd cards they are usually mounted to /sdcard (or some variation of that name) which is usually symlinked to to a directory in /storage like /storage/sdcard0 or /storage/0 sometimes the emulated storage is mounted to /sdcard and the actual path is something like /storage/emulated/legacy. You should be able to use to get the downloads directory. You are best off using the api calls to get directories. Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS);

Since the filesystems and sdcard support varies among devices.

see similar question for more info how to access downloads folder in android?

Usually the DownloadManager handles downloads and the files are then accessed by requesting the file's uri fromthe download manager using a file id to get where file was places which would usually be somewhere in the sdcard/ real or emulated since apps can only read data from certain places on the filesystem outside of their data directory like the sdcard

std::string::data would seem to be sufficient and most efficient. If you want to have non-const memory to manipulate (strange for encryption) you can copy the data to a buffer using memcpy:

unsigned char buffer[mystring.length()];
memcpy(buffer, mystring.data(), mystring.length());

STL fanboys would encourage you to use std::copy instead:

std::copy(mystring.begin(), mystring.end(), buffer);

but there really isn't much of an upside to this. If you need null termination use std::string::c_str() and the various string duplication techniques others have provided, but I'd generally avoid that and just query for the length. Particularly with cryptography you just know somebody is going to try to break it by shoving nulls in to it, and using std::string::data() discourages you from lazily making assumptions about the underlying bits in the string.

I always use requestAnimationFrame() to jump over internal post-event mechanisms and this works perfectly in Firefox. Haven't tested in Chrome.

$("input[type=text]").on('focus', function() {
    requestAnimationFrame(() => $(this).select());
});

This also need.

<?php
header("Access-Control-Allow-Origin: *");

Did you import the packages for the file reading stuff.

import java.io.BufferedReader;
import java.io.FileInputStream;
import java.io.InputStreamReader;

also here

cfiltering(numberOfUsers, numberOfMovies);

Are you trying to create an object or calling a method?

also another thing:

user_movie_matrix[userNo][movieNo]=rating;

you are assigning a value to a member of an instance as if it was a static variable also remove the Th in

private int user_movie_matrix[][];Th

Hope this helps.

You can add a callback function to your DatePicker to tell it to blur the input field before showing the DatePicker.

$('.selector').datepicker({
   beforeShow: function(){$('input').blur();}
});

Note: The iOS keyboard will appear for a fraction of a second and then hide.

Create a DTO as CustomObject

Use below method to convert XML String to DTO using JAXB

private static CustomObject getCustomObject(final String ruleStr) {
    CustomObject customObject = null;
    try {
        JAXBContext jaxbContext = JAXBContext.newInstance(CustomObject.class);
        final StringReader reader = new StringReader(ruleStr);
        Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
        customObject = (CustomObject) jaxbUnmarshaller.unmarshal(reader);
    } catch (JAXBException e) {
        LOGGER.info("getCustomObject parse error: ", e);
    }
    return customObject;
}

Get the array of keys, reverse it, then run your loop

  var keys = Object.keys( obj ).reverse();
  for(var i = 0; i < keys.length; i++){
    var key = keys[i];
    var value = obj[key];
    //do stuff backwards
  }

SELECT rest.field1
FROM mastertable as m
INNER JOIN table1 at t1 on t1.field1 = m.field
INNER JOIN table2 at t2 on t2.field = t1.field
WHERE t1.field3 = (SELECT MAX(field3) FROM table1)

Instead of using a PreferenceActivity to directly load preferences, use an AppCompatActivity or equivalent that loads a PreferenceFragmentCompat that loads your preferences. It's part of the support library (now Android Jetpack) and provides compatibility back to API 14.

In your build.gradle, add a dependency for the preference support library:

dependencies {
    // ...
    implementation "androidx.preference:preference:1.0.0-alpha1"
}

Note: We're going to assume you have your preferences XML already created.

For your activity, create a new activity class. If you're using material themes, you should extend an AppCompatActivity, but you can be flexible with this:

public class MyPreferencesActivity extends AppCompatActivity {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.my_preferences_activity)
        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction()
                    .replace(R.id.fragment_container, MyPreferencesFragment())
                    .commitNow()
        }
    }
}

Now for the important part: create a fragment that loads your preferences from XML:

public class MyPreferencesFragment extends PreferenceFragmentCompat {

    @Override
    public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
        setPreferencesFromResource(R.xml.my_preferences_fragment); // Your preferences fragment
    }
}

For more information, read the Android Developers docs for PreferenceFragmentCompat.

Hi used this thread to get the solution , then i would like to share what i did just in case someone could use it.

What i wanted was to call a macro that change some cells and erase some rows, but i needed for more than 1500 excels( approximately spent 3 minuts for each file)

Mainly problem: -when calling the macro from vbe , i got the same problem, it was imposible to call the macro from PERSONAL.XLSB, when the script oppened the excel didnt execute personal.xlsb and wasnt any option in the macro window

I solved this by keeping open one excel file with the macro loaded(a.xlsm)(before executing the script)

Then i call the macro from the excel oppened by the script

    Option Explicit
    Dim xl
    Dim counter

   counter =10



  Do

  counter = counter + 1

  Set xl = GetObject(, "Excel.Application")
  xl.Application.Workbooks.open "C:\pruebas\macroxavi\IA_030-08-026" & counter & ".xlsx"
  xl.Application.Visible = True
  xl.Application.run "'a.xlsm'!eraserow" 
  Set xl = Nothing


  Loop Until counter = 517

  WScript.Echo "Finished."
  WScript.Quit

Here is the solution I used for Report Server 2008 R2

It should work regardless of what the Report Server will output for use for in its "id" attribute of the table. I don't think you can always assume it will be "ctl31_fixedTable"

I used a mix of the suggestion above and some ways to dynamically load jquery libraries into a page from javascript file found here

On the server go to the directory: C:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\ReportManager\js

Copy the jquery library jquery-1.6.2.min.js into the directory

Create a backup copy of the file ReportingServices.js Edit the file. And append this to the bottom of it:

var jQueryScriptOutputted = false;
function initJQuery() {

    //if the jQuery object isn't available
    if (typeof(jQuery) == 'undefined') {


        if (! jQueryScriptOutputted) {
            //only output the script once..
            jQueryScriptOutputted = true;

            //output the script 
            document.write("<scr" + "ipt type=\"text/javascript\" src=\"../js/jquery-1.6.2.min.js\"></scr" + "ipt>");
         }
        setTimeout("initJQuery()", 50);
    } else {

        $(function() {     

        // Bug-fix on Chrome and Safari etc (webkit)
        if ($.browser.webkit) {

            // Start timer to make sure overflow is set to visible
             setInterval(function () {
                var div = $('table[id*=_fixedTable] > tbody > tr:last > td:last > div')

                div.css('overflow', 'visible');
            }, 1000);
        }

        });
    }        
}

initJQuery();

I had a similar thing to work on, and this is how I did it.

import os

rootdir = os.getcwd()

for subdir, dirs, files in os.walk(rootdir):
    for file in files:
        #print os.path.join(subdir, file)
        filepath = subdir + os.sep + file

        if filepath.endswith(".html"):
            print (filepath)

Hope this helps.

Since all responses to this make use of the now long-deprecated abstract WebMvcConfigurer Adapter instead of the WebMvcInterface (as already noted by @sebdooe), here is a working minimal example for a SpringBoot (2.1.4) application with an Interceptor:

Minimal.java:

@SpringBootApplication
public class Minimal
{
    public static void main(String[] args)
    {
        SpringApplication.run(Minimal.class, args);
    }
}

MinimalController.java:

@RestController
@RequestMapping("/")
public class Controller
{
    @GetMapping("/")
    @ResponseBody
    public ResponseEntity<String> getMinimal()
    {
        System.out.println("MINIMAL: GETMINIMAL()");

        return new ResponseEntity<String>("returnstring", HttpStatus.OK);
    }
}

Config.java:

@Configuration
public class Config implements WebMvcConfigurer
{
    //@Autowired
    //MinimalInterceptor minimalInterceptor;

    @Override
    public void addInterceptors(InterceptorRegistry registry)
    {
        registry.addInterceptor(new MinimalInterceptor());
    }
}

MinimalInterceptor.java:

public class MinimalInterceptor extends HandlerInterceptorAdapter
{
    @Override
    public boolean preHandle(HttpServletRequest requestServlet, HttpServletResponse responseServlet, Object handler) throws Exception
    {
        System.out.println("MINIMAL: INTERCEPTOR PREHANDLE CALLED");

        return true;
    }

    @Override
    public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler, ModelAndView modelAndView) throws Exception
    {
        System.out.println("MINIMAL: INTERCEPTOR POSTHANDLE CALLED");
    }

    @Override
    public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler, Exception exception) throws Exception
    {
        System.out.println("MINIMAL: INTERCEPTOR AFTERCOMPLETION CALLED");
    }
}

works as advertised

The output will give you something like:

The hjpotter92 answer works well enough in certain cases, but I found the iframe content often got bottom-clipped in Firefox & IE, while fine in Chrome.

The following works well for me and fixes the clipping problem. The code was found at http://www.dyn-web.com/tutorials/iframes/height/. I have made a slight modification to take the onload attribute out of the HTML. Place the following code after the <iframe> HTML and before the closing </body> tag:

<script type="text/javascript">
function getDocHeight(doc) {
    doc = doc || document;
    // stackoverflow.com/questions/1145850/
    var body = doc.body, html = doc.documentElement;
    var height = Math.max( body.scrollHeight, body.offsetHeight, 
        html.clientHeight, html.scrollHeight, html.offsetHeight );
    return height;
}

function setIframeHeight(id) {
    var ifrm = document.getElementById(id);
    var doc = ifrm.contentDocument? ifrm.contentDocument: 
        ifrm.contentWindow.document;
    ifrm.style.visibility = 'hidden';
    ifrm.style.height = "10px"; // reset to minimal height ...
    // IE opt. for bing/msn needs a bit added or scrollbar appears
    ifrm.style.height = getDocHeight( doc ) + 4 + "px";
    ifrm.style.visibility = 'visible';
}

document.getElementById('ifrm').onload = function() { // Adjust the Id accordingly
    setIframeHeight(this.id);
}
</script>

Your iframe HTML:

<iframe id="ifrm" src="some-iframe-content.html"></iframe>

Note if you prefer to include the Javascript in the <head> of the document then you can revert to using an inline onload attribute in the iframe HTML, as in the dyn-web web page.

Here you go. Just specify the chars you want to allow on the first line.

char[] chars = "abcdefghijklmnopqrstuvwxyz".toCharArray();
StringBuilder sb = new StringBuilder(20);
Random random = new Random();
for (int i = 0; i < 20; i++) {
    char c = chars[random.nextInt(chars.length)];
    sb.append(c);
}
String output = sb.toString();
System.out.println(output);

If you are using this to generate something sensitive like a password reset URL or session ID cookie or temporary password reset, be sure to use java.security.SecureRandom instead. Values produced by java.util.Random and java.util.concurrent.ThreadLocalRandom are mathematically predictable.

To take a quick look, you can percent-en/decode using this online tool.

You can use an anonymous function to pass the matches to your function:

$result = preg_replace_callback(
    "/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
    function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
    $result
);

Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e would convert a double quote " into \".

Quick simple example using mongo, for an API that provides user auth for ie Angular client

in app.js

var express = require('express');
var MongoStore = require('connect-mongo')(express);

// ...

app.use(express.cookieParser());
// obviously change db settings to suit
app.use(express.session({
    secret: 'blah1234',
    store: new MongoStore({
        db: 'dbname',
        host: 'localhost',
        port: 27017
    })
}));

app.use(app.router);

for your route something like this:

// (mongo connection stuff)

exports.login = function(req, res) {

    var email = req.body.email;
    // use bcrypt in production for password hashing
    var password = req.body.password;

    db.collection('users', function(err, collection) {
        collection.findOne({'email': email, 'password': password}, function(err, user) {
            if (err) {
                res.send(500);
            } else {
                if(user !== null) {
                    req.session.user = user;
                    res.send(200);
                } else {
                    res.send(401);
                }
            }
        });
    });
};

Then in your routes that require auth you can just check for the user session:

if (!req.session.user) {
    res.send(403);
}

Try this, It worked for me

SELECT * FROM (
            SELECT
                [Code],
                [Name],
                [CategoryCode],
                [CreatedDate],
                [ModifiedDate],
                [CreatedBy],
                [ModifiedBy],
                [IsActive],
                ROW_NUMBER() OVER(PARTITION BY [Code],[Name],[CategoryCode] ORDER BY ID DESC) rownumber
            FROM MasterTable
          ) a
        WHERE rownumber = 1 

First create a real, permanent table as a template that has the required layout for the returned temporary table, using a naming convention that identifies it as a template and links it symbolically to the SP, eg tmp_SPName_Output. This table will never contain any data.

In the SP, use INSERT to load data into a temp table following the same naming convention, e.g. #SPName_Output which is assumed to exist. You can test for its existence and return an error if it does not.

Before calling the sp use this simple select to create the temp table:

SELECT TOP(0) * INTO #SPName_Output FROM tmp_SPName_Output;
EXEC SPName;
-- Now process records in #SPName_Output;

This has these distinct advantages:

• The temp table is local to the current session, unlike ##, so will not clash with concurrent calls to the SP from different sessions. It is also dropped automatically when out of scope.
• The template table is maintained alongside the SP, so if changes are made to the output (new columns added, for example) then pre-existing callers of the SP do not break. The caller does not need to be changed.
• You can define any number of output tables with different naming for one SP and fill them all. You can also define alternative outputs with different naming and have the SP check the existence of the temp tables to see which need to be filled.
• Similarly, if major changes are made but you want to keep backwards compatibility, you can have a new template table and naming for the later version but still support the earlier version by checking which temp table the caller has created.

date -d '1 hour ago' '+%Y-%m-%d'

The output would be 2015-06-14.

Firefox Screenshots is a new tool that ships with Firefox. It is not a developer tool, it is aimed at end-users of the browser.

To take a screenshot, click on the page actions menu in the address bar, and click "take a screenshot". If you then click "Save full page", it will save the full page, scrolling for you.

For me it turned out that I had a @JsonManagedReferece in one entity without a @JsonBackReference in the other referenced entity. This caused the marshaller to throw an error.

I would simply do this, which literally follows what your desired logic was:

df.groupby(['org']).mean().groupby(['cluster']).mean()

You can extend jQuery prototype and use your function as a jQuery method.

(function($)
{
    $.fn.MyBlah = function(blah)
    {
        $(this).addClass(blah);
        console.log('blah class added');
    };
})(jQuery);

jQuery(document).ready(function($)
{
    $('#blahElementId').MyBlah('newClass');
});

More info on extending jQuery prototype here: http://api.jquery.com/jquery.fn.extend/

cellspacing (distance between cells) parameter of the TABLE tag is precisely what you want. The disadvantage is it's one value, used both for x and y, you can't choose different spacing or padding vertically/horizontally. There is a CSS property too, but it's not widely supported.

You can check and use their free trial browserstack , saucelabs or browser shots I know this is a very old question and I am answering too late and today there are many options available but may be someone get this usefull.

This should work :

str = str.replace(/[^a-z0-9-]/g, '');

Everything between the indicates what your are looking for

1. / is here to delimit your pattern so you have one to start and one to end
2. [] indicates the pattern your are looking for on one specific character
3. ^ indicates that you want every character NOT corresponding to what follows
4. a-z matches any character between 'a' and 'z' included
5. 0-9 matches any digit between '0' and '9' included (meaning any digit)
6. - the '-' character
7. g at the end is a special parameter saying that you do not want you regex to stop on the first character matching your pattern but to continue on the whole string

Then your expression is delimited by / before and after. So here you say "every character not being a letter, a digit or a '-' will be removed from the string".

For substracting in moment.js:

moment().subtract(1, 'months').format('MMM YYYY');

Documentation:

http://momentjs.com/docs/#/manipulating/subtract/

Before version 2.8.0, the moment#subtract(String, Number) syntax was also supported. It has been deprecated in favor of moment#subtract(Number, String).

  moment().subtract('seconds', 1); // Deprecated in 2.8.0
  moment().subtract(1, 'seconds');

As of 2.12.0 when decimal values are passed for days and months, they are rounded to the nearest integer. Weeks, quarters, and years are converted to days or months, and then rounded to the nearest integer.

  moment().subtract(1.5, 'months') == moment().subtract(2, 'months')
  moment().subtract(.7, 'years') == moment().subtract(8, 'months') //.7*12 = 8.4, rounded to 8

it's so easy...converting a date to calendar like this:

Calendar cal=Calendar.getInstance();
DateFormat format=new SimpleDateFormat("yyyy/mm/dd");
format.format(date);
cal=format.getCalendar();

$("#locationthemes").prop("checked")

You need two backslashes before the dot, one to escape the slash so it gets through, and the other to escape the dot so it becomes literal. Forward slashes and asterisk are treated literal.

str=xpath.replaceAll("\\.", "/*/");          //replaces a literal . with /*/

http://docs.oracle.com/javase/7/docs/api/java/lang/String.html#replaceAll(java.lang.String,%20java.lang.String)

This is not an error. This is a warning. The difference is pretty huge. This particular warning basically means that the <Context> element in Tomcat's server.xml contains an unknown attribute source and that Tomcat doesn't know what to do with this attribute and therefore will ignore it.

Eclipse WTP adds a custom attribute source to the project related <Context> element in the server.xml of Tomcat which identifies the source of the context (the actual project in the workspace which is deployed to the particular server). This way Eclipse can correlate the deployed webapplication with an project in the workspace. Since Tomcat version 6.0.16, any unspecified XML tags and attributes in the server.xml will produce a warning during Tomcat's startup, even though there is no DTD nor XSD for server.xml.

Just ignore it. Your web project is fine. It should run fine. This issue is completely unrelated to JSF.

The issue seems to be with autorelease of objects. NSJSONSerialization JSONObjectWithData is obviously creating some autoreleased objects and passing it back to you. If you try to take that on to a different thread, it will not work since it cannot be deallocated on a different thread.

Trick might be to try doing a mutable copy of that dictionary or array and use it.

NSError *e = nil;
id jsonObject = [NSJSONSerialization 
JSONObjectWithData: data 
options: NSJSONReadingMutableContainers 
error: &e] mutableCopy];

Treating a NSDictionary as NSArray will not result in Bad access exception but instead will probably crash when a method call is made.

Also, may be the options do not really matter here but it is better to give NSJSONReadingMutableContainers | NSJSONReadingMutableContainers | NSJSONReadingAllowFragments but even if they are autoreleased objects it may not solve this issue.

git checkout --theirs path/to/file

I ran into this recently. Our organization restricts the accounts that run application pools to a select list of servers in Active Directory. I found that I had not added one of the machines hosting the application to the "Log On To" list for the account in AD.

It seems to be working fine:

List<BigDecimal> list = Arrays.asList(new BigDecimal("24.455"), new BigDecimal("23.455"), new BigDecimal("28.455"), new BigDecimal("20.455"));
System.out.println("Unsorted list: " + list);
final List<BigDecimal> sortedList = list.stream().sorted((o1, o2) -> o1.compareTo(o2)).collect(Collectors.toList());
System.out.println("Sorted list: " + sortedList);

Example Input/Output

Unsorted list: [24.455, 23.455, 28.455, 20.455]
Sorted list: [20.455, 23.455, 24.455, 28.455]

Are you sure you are not verifying list instead of sortedList [in above example] i.e. you are storing the result of stream() in a new List object and verifying that object?

We'll never convince people to leave IE6 if we keep striving to deliver quality websites to those users.

Only IE7+ understood "position: fixed".

https://developer.mozilla.org/en-US/docs/Web/CSS/position

So you're out of luck for IE6. To get the footer semi-sticky try this:

.main {
  min-height: 100%;
  margin-bottom: -60px;
}
.footer {
  height: 60px;
}

You could also use an iFrame maybe.

This will keep the footer from 'lifting off' from the bottom of the page. If you have more than one page of content then it will push down out of site.

On a philosophical note, I'd rather point IE6 users to http://browsehappy.com/ and spend the time I save hacking for IE6 on something else.

File -> Source Control -> Advanced -> Change Source Control and then unbind and/or disconnect all projects and the solution.

This should remove all bindings from the solution and project files. (After this you can switch the SCC provider in Tools -> Options -> Source Control -> Plug-in Selection).

The SCC specification prescribes that all SCC providers should implement this behavior. (I only tested it for VSS, TFS and AnkhSVN)

If I understand what you are asking, it is a regular expression like this:

^(8768|9875|2353)

This matches the three sets of digit strings at beginning of line only.

In a somewhat related way I was trying to add a remote tracking branch to an existing branch, but did not have access to that remote repository on the system where I wanted to add that remote tracking branch on (because I frequently export a copy of this repo via sneakernet to another system that has the access to push to that remote). I found that there was no way to force adding a remote branch on the local that hadn't been fetched yet (so local did not know that the branch existed on the remote and I would get the error: the requested upstream branch 'origin/remotebranchname' does not exist).

In the end I managed to add the new, previously unknown remote branch (without fetching) by adding a new head file at .git/refs/remotes/origin/remotebranchname and then copying the ref (eyeballing was quickest, lame as it was ;-) from the system with access to the origin repo to the workstation (with the local repo where I was adding the remote branch on).

Once that was done, I could then use git branch --set-upstream-to=origin/remotebranchname

You can use map :

List<String> names = 
    personList.stream()
              .map(Person::getName)
              .collect(Collectors.toList());

EDIT :

In order to combine the Lists of friend names, you need to use flatMap :

List<String> friendNames = 
    personList.stream()
              .flatMap(e->e.getFriends().stream())
              .collect(Collectors.toList());

While answers that refer to @ModelAttribute, @RequestParam, @PathParam and the likes are valid, there is a small gotcha I ran into. The resulting method parameter is a proxy that Spring wraps around your DTO. So, if you attempt to use it in a context that requires your own custom type, you may get some unexpected results.

The following will not work:

@GetMapping(produces = APPLICATION_JSON_VALUE)
public ResponseEntity<CustomDto> request(@ModelAttribute CustomDto dto) {
    return ResponseEntity.ok(dto);
}

In my case, attempting to use it in Jackson binding resulted in a com.fasterxml.jackson.databind.exc.InvalidDefinitionException.

You will need to create a new object from the dto.

Is it not possible in your case to do the AND on several matching results? in pseudocode

regexp_match(pattern1, data) && regexp_match(pattern2, data) && ...

The JQuery code is fine. You must execute in the ready handler not in the window load event.

<script type="text/javascript">
$(function(){
  var aspForm  = $("form#aspnetForm");
  var firstInput = $(":input:not(input[type=button],input[type=submit],button):visible:first", aspForm);
  firstInput.focus();
});
</script>

Update

I tried with the example of Karim79(thanks for the example) and it works fine: http://jsfiddle.net/2sMfU/

It is caused by a lack of precision with doubles / decimals (i.e. - the function will not always give the result you expect).

See the following link: MSDN on Math.Round

Here is the relevant quote:

Because of the loss of precision that can result from representing decimal values as floating-point numbers or performing arithmetic operations on floating-point values, in some cases the Round(Double, Int32, MidpointRounding) method may not appear to round midpoint values as specified by the mode parameter.This is illustrated in the following example, where 2.135 is rounded to 2.13 instead of 2.14.This occurs because internally the method multiplies value by 10digits, and the multiplication operation in this case suffers from a loss of precision.

Edit: fsw has been merged into fswatch. In this answer, any reference to fsw should now read fswatch.

I wrote an fswatch replacement in C++ called fsw which features several improvements:

• It's a GNU Build System project which builds on any supported platform (OS X v. >= 10.6) with

  ./configure && make && sudo make install
  

• Multiple paths can be passed as different arguments:

  fsw file-0 ... file-n 
  

• It dumps a detailed record with all the event information such as:

  Sat Feb 15 00:53:45 2014 - /path/to/file:inodeMetaMod modified isFile 
  

• Its output is easy to parse so that fsw output can be piped to another process.

• Latency can be customised with -l, --latency.
• Numeric event flags can be written instead of textual ones with -n, --numeric.
• The time format can be customised using strftime format strings with -t, --time-format.
• The time can be the local time of the machine (by default) or UTC time with -u, --utc-time.

Getting fsw:

fsw is hosted on GitHub and can be obtained cloning its repository:

    git clone https://github.com/emcrisostomo/fsw

Installing fsw:

fsw can be installed using the following commands:

    ./configure && make && sudo make install

Further information:

I also wrote an introductory blog post where you can find a couple of examples about how fsw works.

Here's what I did, for stamping the AssemblyFileVersion attribute.

Removed the AssemblyFileVersion from AssemblyInfo.cs

Add a new, empty, file called AssemblyFileInfo.cs to the project.

Install the MSBuild community tasks toolset on the hudson build machine or as a NuGet dependency in your project.

Edit the project (csproj) file , it's just an msbuild file, and add the following.

Somewhere there'll be a <PropertyGroup> stating the version. Change that so it reads e.g.

 <Major>1</Major>
 <Minor>0</Minor>
 <!--Hudson sets BUILD_NUMBER and SVN_REVISION -->
 <Build>$(BUILD_NUMBER)</Build>
 <Revision>$(SVN_REVISION)</Revision>

Hudson provides those env variables you see there when the project is built on hudson (assuming it's fetched from subversion).

At the bottom of the project file, add

 <Import Project="$(MSBuildExtensionsPath)\MSBuildCommunityTasks\MSBuild.Community.Tasks.Targets" Condition="Exists('$(MSBuildExtensionsPath)\MSBuildCommunityTasks\MSBuild.Community.Tasks.Targets')" />
  <Target Name="BeforeBuild" Condition="Exists('$(MSBuildExtensionsPath)\MSBuildCommunityTasks\MSBuild.Community.Tasks.Targets')">
    <Message Text="Version: $(Major).$(Minor).$(Build).$(Revision)" />
    <AssemblyInfo CodeLanguage="CS" OutputFile="AssemblyFileInfo.cs" AssemblyFileVersion="$(Major).$(Minor).$(Build).$(Revision)" AssemblyConfiguration="$(Configuration)" Condition="$(Revision) != '' " />
  </Target>

This uses the MSBuildCommunityTasks to generate the AssemblyFileVersion.cs to include an AssemblyFileVersion attribute before the project is built. You could do this for any/all of the version attributes if you want.

The result is, whenever you issue a hudson build, the resulting assembly gets an AssemblyFileVersion of 1.0.HUDSON_BUILD_NR.SVN_REVISION e.g. 1.0.6.2632 , which means the 6'th build # in hudson, buit from the subversion revision 2632.

Calling -sizeToFit on UILabel instance will automatically resize it to fit text it displays, no calculating required. If you need the size, you can get it from label's frame property after that.

label.numberOfLines = 0; // allows label to have as many lines as needed
label.text = @"some long text";
[label sizeToFit];
NSLog(@"Label's frame is: %@", NSStringFromCGRect(label.frame));

According to HTML5 drafts, the checked attribute is a “boolean attribute”, and “The presence of a boolean attribute on an element represents the true value, and the absence of the attribute represents the false value.” It is the name of the attribute that matters, and suffices. Thus, to make a checkbox initially checked, you use

<input type=checkbox checked>

By default, in the absence of the checked attribute, a checkbox is initially unchecked:

<input type=checkbox>

Keeping things this way keeps them simple, but if you need to conform to XML syntax (i.e. to use HTML5 in XHTML linearization), you cannot use an attribute name alone. Then the allowed (as per HTML5 drafts) values are the empty string and the string checked, case insensitively. Example:

<input type="checkbox" checked="checked" />

b = a[a>threshold] this should do

I tested as follows:

import numpy as np, datetime
# array of zeros and ones interleaved
lrg = np.arange(2).reshape((2,-1)).repeat(1000000,-1).flatten()

t0 = datetime.datetime.now()
flt = lrg[lrg==0]
print datetime.datetime.now() - t0

t0 = datetime.datetime.now()
flt = np.array(filter(lambda x:x==0, lrg))
print datetime.datetime.now() - t0

I got

$ python test.py

How to get duplicate record in table

 SELECT COUNT(EmpCode),EmpCode FROM tbl_Employees WHERE Status=1 
 GROUP BY EmpCode HAVING COUNT(EmpCode) > 1

For anyone looking for a concise, pictorial answer:

https://hanaskuliah.wordpress.com/2015/12/07/android-5-development-part-6-fragment/

And,

This is what I have so far. It covers both 1 and 3. I'm however still struggling with 2 since I'm not that familiar with Prototype (I'm more a jQuery type of guy).

function isVisible( elem ) {
    var $elem = $(elem);

    // First check if elem is hidden through css as this is not very costly:
    if ($elem.getStyle('display') == 'none' || $elem.getStyle('visibility') == 'hidden' ) {
        //elem is set through CSS stylesheet or inline to invisible
        return false;
    }

    //Now check for the elem being outside of the viewport
    var $elemOffset = $elem.viewportOffset();
    if ($elemOffset.left < 0 || $elemOffset.top < 0) {
        //elem is left of or above viewport
        return false;
    }
    var vp = document.viewport.getDimensions();
    if ($elemOffset.left > vp.width || $elemOffset.top > vp.height) {
        //elem is below or right of vp
        return false;
    }

    //Now check for elements positioned on top:
    //TODO: Build check for this using Prototype...
    //Neither of these was true, so the elem was visible:
    return true;
}

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

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

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

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

To break it down:

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

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

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

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

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

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

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

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

What you need to be certain is that the service using the DB is not running.

Experienced same issue, running some Java apps, and none of the above options worked, not even restart.

Run a ps aux kill the main service using the DB.

• kill -9 'PID' of the application
• or if the application runs as a service make sure to run the service stop cmd for your OS.

After that the default way to drop a table will work flawlessly.

In my example were issues with

dict does not keep its elements' order. What you need is an OrderedDict: http://docs.python.org/library/collections.html#collections.OrderedDict

edit

Usage example:

>>> from collections import OrderedDict
>>> a = {'foo': 1, 'bar': 2}
>>> a
{'foo': 1, 'bar': 2}
>>> b = OrderedDict(sorted(a.items()))
>>> b
OrderedDict([('bar', 2), ('foo', 1)])
>>> b['foo']
1
>>> b['bar']

Actually, RFC 2965, the document that defines how cookies work, specifies that there should be no maximum length of a cookie's key or value size, and encourages implementations to support arbitrarily large cookies. Each browser's implementation maximum will necessarily be different, so consult individual browser documentation.

See section 5.3, "Implementation Limits", in the RFC.

Following @acdcjunior answer, this is how I implemented it

service:

  get(url, params): Promise<Object> {

            return this.sendRequest(this.baseUrl + url, 'get', null, params)
                .map((res) => {
                    return res as Object
                }).catch((e) => {
                    return Observable.of(e);
                })
                .toPromise();
        }

caller:

this.dataService.get(baseUrl, params)
            .then((object) => {
                if(object['name'] === 'HttpErrorResponse') {
                            this.error = true;
                           //or any handle
                } else {
                    this.myObj = object as MyClass 
                }
           });

if you embed the pdf in your webpage and reference the object id, you should be able to do it.

eg. in your HTML:

<object ID="examplePDF" type="application/pdf" data="example.pdf" width="500" height="500">

in your javascript:

<script>

var pdf = document.getElementById("examplePDF");

pdf.print();

</script>

I hope that helps.

To make a dropdown list you need two properties:

1. a property to which you will bind to (usually a scalar property of type integer or string)
2. a list of items containing two properties (one for the values and one for the text)

In your case you only have a list of string which cannot be exploited to create a usable drop down list.

While for number 2. you could have the value and the text be the same you need a property to bind to. You could use a weakly typed version of the helper:

@model List<string>
@Html.DropDownList(
    "Foo", 
    new SelectList(
        Model.Select(x => new { Value = x, Text = x }),
        "Value",
        "Text"
    )
)

where Foo will be the name of the ddl and used by the default model binder. So the generated markup might look something like this:

<select name="Foo" id="Foo">
    <option value="item 1">item 1</option>
    <option value="item 2">item 2</option>
    <option value="item 3">item 3</option>
    ...
</select>

This being said a far better view model for a drop down list is the following:

public class MyListModel
{
    public string SelectedItemId { get; set; }
    public IEnumerable<SelectListItem> Items { get; set; }
}

and then:

@model MyListModel
@Html.DropDownListFor(
    x => x.SelectedItemId,
    new SelectList(Model.Items, "Value", "Text")
)

and if you wanted to preselect some option in this list all you need to do is to set the SelectedItemId property of this view model to the corresponding Value of some element in the Items collection.

Just wrap your WebElement into Select Object as shown below

Select dropdown = new Select(driver.findElement(By.id("identifier")));

Once this is done you can select the required value in 3 ways. Consider an HTML file like this

<html>
<body>
<select id = "designation">
<option value = "MD">MD</option>
<option value = "prog"> Programmer </option>
<option value = "CEO"> CEO </option>
</option>
</select>
<body>
</html>

Now to identify dropdown do

Select dropdown = new Select(driver.findElement(By.id("designation")));

To select its option say 'Programmer' you can do

dropdown.selectByVisibleText("Programmer ");

or

 dropdown.selectByIndex(1);

or

 dropdown.selectByValue("prog");

Happy Coding :)

Instead of using datetime.now you should be really using from django.utils.timezone import now

Reference:

• Documentation for django.utils.timezone.now

so go for something like this:

from django.utils.timezone import now


created_date = models.DateTimeField(default=now, editable=False)

If you're doing this in your erb view (for Rails), be mindful of the <% and <%= differences. What you'd want is:

<% (1..x).each do |i| %>
  Code to display using <%= stuff %> that you want to display    
<% end %>

For plain Ruby, you can refer to: http://www.tutorialspoint.com/ruby/ruby_loops.htm

Try this:

 List<Double> l1= new ArrayList<Double>();
 l1.add(1.38);
 l1.add(2.56);
 l1.add(4.3);

You can always use strtotime to minus the number of days from the current date:

$users = Users::where('status_id', 'active')
           ->where( 'created_at', '>', date('Y-m-d', strtotime("-30 days"))
           ->get();

Use this String.valueOf(value);

Short answer:

@Autowired
private WebApplicationContext webApplicationContext;

@Autowired
private Filter springSecurityFilterChain;

@Before
public void setUp() throws Exception {
    final MockHttpServletRequestBuilder defaultRequestBuilder = get("/dummy-path");
    this.mockMvc = MockMvcBuilders.webAppContextSetup(this.webApplicationContext)
            .defaultRequest(defaultRequestBuilder)
            .alwaysDo(result -> setSessionBackOnRequestBuilder(defaultRequestBuilder, result.getRequest()))
            .apply(springSecurity(springSecurityFilterChain))
            .build();
}

private MockHttpServletRequest setSessionBackOnRequestBuilder(final MockHttpServletRequestBuilder requestBuilder,
                                                             final MockHttpServletRequest request) {
    requestBuilder.session((MockHttpSession) request.getSession());
    return request;
}

First, try changing <a>Link</a> to <span id=test><a>Link</a></span>.

Then, add something like this in the javascript function that you're calling:

var abc = 'somelink';
document.getElementById('test').innerHTML = '<a href="' + abc + '">Link</a>';

This way the link will look like this:

<a href="somelink">Link</a>

If you want to print the last 10 lines, use

tail(dataset, 10)

for the first 10, you could also do

head(dataset, 10)

Something like this?

int[][] pixels = new int[w][h];

for( int i = 0; i < w; i++ )
    for( int j = 0; j < h; j++ )
        pixels[i][j] = img.getRGB( i, j );

In the Xcode 6.2, this also works

let appDelegate = UIApplication.sharedApplication().delegate! as AppDelegate

let aVariable = appDelegate.someVariable

The second option really isn't the same as the others - if the string is "///foo" it will become "foo" instead of "//foo".

The first option needs a bit more work to understand than the third - I would view the Substring option as the most common and readable.

(Obviously each of them as an individual statement won't do anything useful - you'll need to assign the result to a variable, possibly data itself.)

I wouldn't take performance into consideration here unless it was actually becoming a problem for you - in which case the only way you'd know would be to have test cases, and then it's easy to just run those test cases for each option and compare the results. I'd expect Substring to probably be the fastest here, simply because Substring always ends up creating a string from a single chunk of the original input, whereas Remove has to at least potentially glue together a start chunk and an end chunk.

Bouncy Castle still requires jars installed as far as I can tell.

I did a little test and it seemed to confirm this:

http://www.bouncycastle.org/wiki/display/JA1/Frequently+Asked+Questions

VS Code supports this out of the box now, but the feature sometimes works and sometimes doesn't, it seems. As far as I could find out, VS Code has to load data needed for auto imports, which happens more or less like this:

• Load data for all exports from your local files
• Load data for all exports from node_modules/@types
• Load data for all exports from node_modules/{packageName} only if any of your local files is importing them

This is better described in this comment: https://github.com/microsoft/TypeScript/issues/31763#issuecomment-537226190.

Due to bugs either in VS Code or in specific packages' type declarations, the last two points don't always work. That was my case, I couldn't see react-bootstrap auto imports in a plain Create-React-App. What finally fixed it was manually copying the package folder from node_modules to node_modules/@types and leaving there only the type declaration files, e.g. Button.d.ts. This is not great because if you ever delete node_modules folder it will stop working again. But I prefer this from always having to manually type imports. This was my last resort after trying and failing with these methods:

• Update VS Code (v. 1.45.1)
• Install types for your package, e.g. npm install --save @types/react-bootstrap
• Add jsconfig.json file and play with the settings as other people suggested
• Try out all the plugins for automatic imports

I hope this helps someone!

I have a data set with Time as the x-axis, and Intensity as y-axis. I'd need to first delete all the default axes except the axes' labels with:

plot(Time,Intensity,axes=F)

Then I rebuild the plot's elements with:

box() # create a wrap around the points plotted
axis(labels=NA,side=1,tck=-0.015,at=c(seq(from=0,to=1000,by=100))) # labels = NA prevents the creation of the numbers and tick marks, tck is how long the tick mark is.
axis(labels=NA,side=2,tck=-0.015)
axis(lwd=0,side=1,line=-0.4,at=c(seq(from=0,to=1000,by=100))) # lwd option sets the tick mark to 0 length because tck already takes care of the mark
axis(lwd=0,line=-0.4,side=2,las=1) # las changes the direction of the number labels to horizontal instead of vertical.

So, at = c(...) specifies the collection of positions to put the tick marks. Here I'd like to put the marks at 0, 100, 200,..., 1000. seq(from =...,to =...,by =...) gives me the choice of limits and the increments.

I fixed this by updating the Request class that my Controller receives.

I removed the following class level annotation from my Request class on my server side. After that my client didn't get 415 error.

import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement

int index = -1;
index = words.Any (word => { index++; return word.IsKey; }) ? index : -1;

With regard to using :: instead of REM for comments: be careful! :: is a special case of a CALL label that acts like a comment. When used inside brackets, for instance in a FOR or IF loop, the function will prematurely exit. Very frustrating to debug!

See http://www.ss64.com/nt/rem.html for a full description.

(adding as a new answer instead of a comment to the first mention of this above because I'm not worthy of commeting yet :0)

Ok @Adam and @Kimvais were right, paramiko cannot parse .ppk files.

So the way to go (thanks to @JimB too) is to convert .ppk file to openssh private key format; this can be achieved using Puttygen as described here.

Then it's very simple getting connected with it:

import paramiko
ssh = paramiko.SSHClient()

ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

ssh.connect('<hostname>', username='<username>', password='<password>', key_filename='<path/to/openssh-private-key-file>')

stdin, stdout, stderr = ssh.exec_command('ls')
print stdout.readlines()
ssh.close()

The “user is currently connected to it” might be SQL Server Management Studio window itself. Try selecting the master database and running the ALTER query again.

To check if variable is null or empty use this:

IF LEN(ISNULL(@var, '')) = 0

So if want to set the value of an environment variable to something different for every build then we can pass these values during build time and we don't need to change our docker file every time.

While ENV, once set cannot be overwritten through command line values. So, if we want to have our environment variable to have different values for different builds then we could use ARG and set default values in our docker file. And when we want to overwrite these values then we can do so using --build-args at every build without changing our docker file.

For more details, you can refer this.

Quoting from http://dev.mysql.com/doc/refman/5.1/en/create-table.html

{INDEX|KEY}

So KEY is an INDEX ;)

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

start myProgram.exe param1
exit

Don't forget to enable tcp/ip connections in SQL SERVER Configuration tools

The comparator should be only for the key, not for the whole entry. It sorts the entries based on the keys.

You should change it to something as follows

SortedMap<String, Double> myMap = 
    new TreeMap<String, Double>(new Comparator<String>()
    {
        public int compare(String o1, String o2)
        {
            return o1.compareTo(o2);
        } 
});

Update

You can do something as follows (create a list of entries in the map and sort the list base on value, but note this not going to sort the map itself) -

List<Map.Entry<String, Double>> entryList = new ArrayList<Map.Entry<String, Double>>(myMap.entrySet());
    Collections.sort(entryList, new Comparator<Map.Entry<String, Double>>() {
        @Override
        public int compare(Entry<String, Double> o1, Entry<String, Double> o2) {
            return o1.getValue().compareTo(o2.getValue());
        }
    });

To all those who know more than me, rather than marking it unhelpful or misleading, read it one more time. I had issues with my Virtual Machine (VM) becoming unresponsive due to all resources being consumed by locked threads, so killing threads is the only option I had. I am not recommending this to anyone who are running long queries but may help to those who are stuck with unresponsive VM or something. Its up-to individuals to take the call. Yes it will kill your query but it saved my VM machine being destroyed.

Serverstack already answered similar question. It solved my issue with SQL on VM machine. Please check here

You need to run following command to fix issues with indexes.

exec sp_updatestats

Python uses not instead of ! for negation.

Try

if not var: 
    print "learnt stuff"

instead

To avoid problems of character encoding in sending emails using the class PHPMailer we can configure it to send it with UTF-8 character encoding using the "CharSet" parameter, as we can see in the following Php code:

$mail = new PHPMailer();
$mail->From = '[email protected]';
$mail->FromName = 'Mi nombre';
$mail->AddAddress('[email protected]');
$mail->Subject = 'Prueba';
$mail->Body = '';
$mail->IsHTML(true);


// Active condition utf-8
$mail->CharSet = 'UTF-8';


// Send mail
$mail->Send();

Looks like other answers are using sorting. That's not optimal from performance point of view because it takes O(n logn) time. It is possible to calculate median in O(n) time instead. The generalized version of this problem is known as "n-order statistics" which means finding an element K in a set such that we have n elements smaller or equal to K and rest are larger or equal K. So 0th order statistic would be minimal element in the set (Note: Some literature use index from 1 to N instead of 0 to N-1). Median is simply (Count-1)/2-order statistic.

Below is the code adopted from Introduction to Algorithms by Cormen et al, 3rd Edition.

/// <summary>
/// Partitions the given list around a pivot element such that all elements on left of pivot are <= pivot
/// and the ones at thr right are > pivot. This method can be used for sorting, N-order statistics such as
/// as median finding algorithms.
/// Pivot is selected ranodmly if random number generator is supplied else its selected as last element in the list.
/// Reference: Introduction to Algorithms 3rd Edition, Corman et al, pp 171
/// </summary>
private static int Partition<T>(this IList<T> list, int start, int end, Random rnd = null) where T : IComparable<T>
{
    if (rnd != null)
        list.Swap(end, rnd.Next(start, end+1));

    var pivot = list[end];
    var lastLow = start - 1;
    for (var i = start; i < end; i++)
    {
        if (list[i].CompareTo(pivot) <= 0)
            list.Swap(i, ++lastLow);
    }
    list.Swap(end, ++lastLow);
    return lastLow;
}

/// <summary>
/// Returns Nth smallest element from the list. Here n starts from 0 so that n=0 returns minimum, n=1 returns 2nd smallest element etc.
/// Note: specified list would be mutated in the process.
/// Reference: Introduction to Algorithms 3rd Edition, Corman et al, pp 216
/// </summary>
public static T NthOrderStatistic<T>(this IList<T> list, int n, Random rnd = null) where T : IComparable<T>
{
    return NthOrderStatistic(list, n, 0, list.Count - 1, rnd);
}
private static T NthOrderStatistic<T>(this IList<T> list, int n, int start, int end, Random rnd) where T : IComparable<T>
{
    while (true)
    {
        var pivotIndex = list.Partition(start, end, rnd);
        if (pivotIndex == n)
            return list[pivotIndex];

        if (n < pivotIndex)
            end = pivotIndex - 1;
        else
            start = pivotIndex + 1;
    }
}

public static void Swap<T>(this IList<T> list, int i, int j)
{
    if (i==j)   //This check is not required but Partition function may make many calls so its for perf reason
        return;
    var temp = list[i];
    list[i] = list[j];
    list[j] = temp;
}

/// <summary>
/// Note: specified list would be mutated in the process.
/// </summary>
public static T Median<T>(this IList<T> list) where T : IComparable<T>
{
    return list.NthOrderStatistic((list.Count - 1)/2);
}

public static double Median<T>(this IEnumerable<T> sequence, Func<T, double> getValue)
{
    var list = sequence.Select(getValue).ToList();
    var mid = (list.Count - 1) / 2;
    return list.NthOrderStatistic(mid);
}

Few notes:

1. This code replaces tail recursive code from the original version in book in to iterative loop.
2. It also eliminates unnecessary extra check from original version when start==end.
3. I've provided two version of Median, one that accepts IEnumerable and then creates a list. If you use the version that accepts IList then keep in mind it modifies the order in list.
4. Above methods calculates median or any i-order statistics in O(n) expected time. If you want O(n) worse case time then there is technique to use median-of-median. While this would improve worse case performance, it degrades average case because constant in O(n) is now larger. However if you would be calculating median mostly on very large data then its worth to look at.
5. The NthOrderStatistics method allows to pass random number generator which would be then used to choose random pivot during partition. This is generally not necessary unless you know your data has certain patterns so that last element won't be random enough or if somehow your code is exposed outside for targeted exploitation.
6. Definition of median is clear if you have odd number of elements. It's just the element with index (Count-1)/2 in sorted array. But when you even number of element (Count-1)/2 is not an integer anymore and you have two medians: Lower median Math.Floor((Count-1)/2) and Math.Ceiling((Count-1)/2). Some textbooks use lower median as "standard" while others propose to use average of two. This question becomes particularly critical for set of 2 elements. Above code returns lower median. If you wanted instead average of lower and upper then you need to call above code twice. In that case make sure to measure performance for your data to decide if you should use above code VS just straight sorting.
7. For .net 4.5+ you can add MethodImplOptions.AggressiveInlining attribute on Swap<T> method for slightly improved performance.

I've been swearing at this for a while. Zoom is definitely not the solutions, it works in chrome, it works partially in IE but moves the entire html div, firefox doesnt do a thing.

My solution that worked for me was using both a scaling and a translation, and also adding the original height and weight and then setting the height and weight of the div itself:

#miniPreview {
transform: translate(-710px, -1000px) rotate(0rad) skewX(0rad) scale(0.3, 0.3);
transform-origin: 1010px 1429px 0px;
width: 337px;
height: 476px;

Obviously change these to your own needs. It gave me the same result in all browsers.

Use

$route.reload();

remember to inject $route to your controller.

Roughly you can have 3 choices to display RTSP video stream in a web page:

1. Realplayer
2. Quicktime player
3. VLC player

You can find the code to embed the activeX via google search.

As far as I know, there are some limitations for each player.

1. Realplayer does not support H.264 video natively, you must install a quicktime plugin for Realplayer to achieve H.264 decoding.
2. Quicktime player does not support RTP/AVP/TCP transport, and it's RTP/AVP (UDP) transport does not include NAT hole punching. Thus the only feasible transport is HTTP tunneling in WAN deployment.
3. VLC neither supports NAT hole punching for RTP/AVP transport, but RTP/AVP/TCP transport is available.

There are 2 main solutions:

The pure HTML one:

<input type="text" id="Textbox" name="Textbox" maxlength="10" />

The JavaScript one (attach it to a onKey Event):

function limitText(limitField, limitNum) {
    if (limitField.value.length > limitNum) {
        limitField.value = limitField.value.substring(0, limitNum);
    } 
}

But anyway, there is no good solution. You can not adapt to every client's bad HTML implementation, it's an impossible fight to win. That's why it's far better to check it on the server side, with a PHP / Python / whatever script.

First of all, never never never use System.exit(0). It is like making a person sleep punching him on the head!

Second: I'm facing this problem. Before sharing my solution a I want to share my thoughts.

I think that an "Exit Button" is stupid. Really really really stupid. And I think that users (consumer) that ask for an exit button for your application is stupid too. They don't understand how the OS is working and how is managing resources (and it does a great job).

I think that if you write a good piece of code that do the right things (updates, saves, and pushes) at the right moment and conditions and using the correct things (Service and Receiver) it will work pretty well and no one will complain.

But to do that you have to study and learn how things works on Android. Anyway, this is my solution to provide to users an "Exit Button".

I created an Options Menu always visible in each activity (I've a super activity that do that).

When the user clicks on that button this is what happens:

Intent intent = new Intent(this, DashBoardActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

SharedPreferences settings = getSharedPreferences(getString(PREF_ID), Context.MODE_PRIVATE);
SharedPreferences.Editor editor = settings.edit();
editor.putBoolean(FORCE_EXIT_APPLICATION, true);

  // Commit the edits!
editor.commit();
startActivity(intent);
finish();

So I'm saving in SharedPreferences that I want to kill my app, and I start an Intent. Please look at those flags; those will clear all my backstack calling my DashBoard Activity that is my "home" activity.

So in my Dashboard Activity I run this method in the onResume:

private void checkIfForceKill() {

    // CHECK IF I NEED TO KILL THE APP

    // Restore preferences
    SharedPreferences settings = getSharedPreferences(
            getString(MXMSettingHolder.PREF_ID), Context.MODE_PRIVATE);
    boolean forceKill = settings.getBoolean(
            MusicSinglePaneActivity.FORCE_EXIT_APPLICATION, false);

    if (forceKill) {

        //CLEAR THE FORCE_EXIT SETTINGS
        SharedPreferences.Editor editor = settings.edit();
        editor.putBoolean(FORCE_EXIT_APPLICATION, false);

        // Commit the edits!
        editor.commit();

        //HERE STOP ALL YOUR SERVICES
        finish();
    }
}

And it will work pretty well.

The only thing that I don't understand why it's happening is that when I do the last finish (and I've checked: it's following all the correct flow of onPause ? onStop ? onDestroy) the application is still on the recent activity (but it's blank).

It seems like the latest intent (that has started the DashboardActivity) is still in the system.

I've to dig more in order to also remove it.

Parentheses in function definition

Parentheses () are being used in function definition:

function_name () { command1 ; command2 ; }

That is the reason you have to escape parentheses even in command parameters:

$ echo (
bash: syntax error near unexpected token `newline'

$ echo \(
(

$ echo () { command echo The command echo was redefined. ; }
$ echo anything
The command echo was redefined.

You can delete any QuerySet you'd like. For example, to delete all blog posts with some Post model

Post.objects.all().delete()

and to delete any Post with a future publication date

Post.objects.filter(pub_date__gt=datetime.now()).delete()

You do, however, need to come up with a way to narrow down your QuerySet. If you just want a view to delete a particular object, look into the delete generic view.

EDIT:

Sorry for the misunderstanding. I think the answer is somewhere between. To implement your own, combine ModelForms and generic views. Otherwise, look into 3rd party apps that provide similar functionality. In a related question, the recommendation was django-filter.

ALTER TABLE xxx AUTO_INCREMENT =1; or clear your table by TRUNCATE

First check if mingw32-make is installed on your system. Use mingw32-make.exe command in windows terminal or cmd to check, else install the package mingw32-make-bin.

then go to bin directory default ( C:\MinGW\bin) create new file make.bat

@echo off
"%~dp0mingw32-make.exe" %*

add the above content and save it

set the env variable in powershell

$Env:CC="gcc"

then compile the file

make hello

where hello.c is the name of source code

I came here because I had the same issue. I wanted to present the options to the user while leaving the option of remaining empty. Although this is possible to explicitly code using checkboxes that would complicate the back end.

Having the user Control+click is almost as good as having them uncheck it through the console. Catching the mousedown is to early and onclick is too late.

Well, at last here is a solution! Just put these few lines once on the page and you have it made for all radio buttons on the page. You can even fiddle with the selector to customize it.

window.onload = function() {_x000D_
  document.querySelectorAll("INPUT[type='radio']").forEach(function(rd) {_x000D_
    rd.addEventListener("mousedown", function() {_x000D_
      if(this.checked) {_x000D_
        this.onclick=function() {_x000D_
          this.checked=false_x000D_
        }_x000D_
      } else {_x000D_
        this.onclick=null_x000D_
      }_x000D_
    })_x000D_
  })_x000D_
}

<input type=radio name=unchecksample> Number One<br>_x000D_
<input type=radio name=unchecksample> Number Two<br>_x000D_
<input type=radio name=unchecksample> Number Three<br>_x000D_
<input type=radio name=unchecksample> Number Four<br>_x000D_
<input type=radio name=unchecksample> Number Five<br>

TLDR;

use location.href or better use window.location.href;

However if you read this you will gain undeniable proof.

The truth is it's fine to use but why do things that are questionable. You should take the higher road and just do it the way that it probably should be done.

location = "#/mypath/otherside"
var sections = location.split('/')

This code is perfectly correct syntax-wise, logic wise, type-wise you know the only thing wrong with it?

it has location instead of location.href

what about this

var mystring = location = "#/some/spa/route"

what is the value of mystring? does anyone really know without doing some test. No one knows what exactly will happen here. Hell I just wrote this and I don't even know what it does. location is an object but I am assigning a string will it pass the string or pass the location object. Lets say there is some answer to how this should be implemented. Can you guarantee all browsers will do the same thing?

This i can pretty much guess all browsers will handle the same.

var mystring = location.href = "#/some/spa/route"

What about if you place this into typescript will it break because the type compiler will say this is suppose to be an object?

This conversation is so much deeper than just the location object however. What this conversion is about what kind of programmer you want to be?

If you take this short-cut, yea it might be okay today, ye it might be okay tomorrow, hell it might be okay forever, but you sir are now a bad programmer. It won't be okay for you and it will fail you.

There will be more objects. There will be new syntax.

You might define a getter that takes only a string but returns an object and the worst part is you will think you are doing something correct, you might think you are brilliant for this clever method because people here have shamefully led you astray.

var Person.name = {first:"John":last:"Doe"}
console.log(Person.name) // "John Doe"

With getters and setters this code would actually work, but just because it can be done doesn't mean it's 'WISE' to do so.

Most people who are programming love to program and love to get better. Over the last few years I have gotten quite good and learn a lot. The most important thing I know now especially when you write Libraries is consistency and predictability.

Do the things that you can consistently do.

+"2" <-- this right here parses the string to a number. should you use it? or should you use parseInt("2")?

what about var num =+"2"?

From what you have learn, from the minds of stackoverflow i am not too hopefully.

If you start following these 2 words consistent and predictable. You will know the right answer to a ton of questions on stackoverflow.

Let me show you how this pays off. Normally I place ; on every line of javascript i write. I know it's more expressive. I know it's more clear. I have followed my rules. One day i decided not to. Why? Because so many people are telling me that it is not needed anymore and JavaScript can do without it. So what i decided to do this. Now because I have become sure of my self as a programmer (as you should enjoy the fruit of mastering a language) i wrote something very simple and i didn't check it. I erased one comma and I didn't think I needed to re-test for such a simple thing as removing one comma.

I wrote something similar to this in es6 and babel

var a = "hello world"
(async function(){
  //do work
})()

This code fail and took forever to figure out. For some reason what it saw was

var a = "hello world"(async function(){})()

hidden deep within the source code it was telling me "hello world" is not a function.

For more fun node doesn't show the source maps of transpiled code.

Wasted so much stupid time. I was presenting to someone as well about how ES6 is brilliant and then I had to start debugging and demonstrate how headache free and better ES6 is. Not convincing is it.

I hope this answered your question. This being an old question it's more for the future generation, people who are still learning.

Question when people say it doesn't matter either way works. Chances are a wiser more experienced person will tell you other wise.

what if someone overwrite the location object. They will do a shim for older browsers. It will get some new feature that needs to be shimmed and your 3 year old code will fail.

My last note to ponder upon.

Writing clean, clear purposeful code does something for your code that can't be answer with right or wrong. What it does is it make your code an enabler.

You can use more things plugins, Libraries with out fear of interruption between the codes.

for the record. use

window.location.href

I would recommend using rgba(255,255,255,0) because broken (newest) safari thinks that if you are using transparent or rgba(0,0,0,0) in linear-gradent you really mean gray, For more info please head to - What happens in Safari with the transparent color?

How to compile a plugin - For making VST plugins in C++Builder, first you need the VST sdk by Steinberg. It's available from the Yvan Grabit's site (the link is at the top of the page).

The next thing you need to do is create a .def file (for example : myplugin.def). This needs to contain at least the following lines:

EXPORTS main=_main

Borland compilers add an underscore to function names, and this exports the main() function the way a VST host expects it. For more information about .def files, see the C++Builder help files.

This is not enough, though. If you're going to use any VCL element (anything to do with forms or components), you have to take care your plugin doesn't crash Cubase (or another VST host, for that matter). Here's how:

1. Include float.h.

2. In the constructor of your effect class, write

   _control87(PC_64|MCW_EM,MCW_PC|MCW_EM);
   

That should do the trick.

Here are some more useful sites:

First: monkey patching is an evil hack (in my opinion).

It is often used to replace a method on the module or class level with a custom implementation.

The most common usecase is adding a workaround for a bug in a module or class when you can't replace the original code. In this case you replace the "wrong" code through monkey patching with an implementation inside your own module/package.

Maybe you could try this code:

import java.io.*;
public class Test
{
public static void main(String[] args)
{
try
  {
  BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
  String userInput = in.readLine();
  System.out.println("\n\nUser entered -> " + userInput);
  }
  catch(IOException e)
  {
  System.out.println("IOException has been caught");
  }
 }
}

net use f: \\\VFServer"\HQ Publications" /persistent:yes

Note that the first quotation mark goes before the leading \ and the second goes after the end of the folder name.

If you also want to keep hash and get parameter, you can do something like this (fill redirectMap at filter init):

String uri = request.getRequestURI();

String[] uriParts = uri.split("[#?]");
String path = uriParts[0];
String rest = uri.substring(uriParts[0].length());

if(redirectMap.containsKey(path)) {
    response.sendRedirect(redirectMap.get(path) + rest);
} else {
    chain.doFilter(request, response);
}

You may put an inner div in the container that is enough wide to hold all the floated divs.

#container {_x000D_
  background-color: red;_x000D_
  overflow: hidden;_x000D_
  width: 200px;_x000D_
}_x000D_
_x000D_
#inner {_x000D_
  overflow: hidden;_x000D_
  width: 2000px;_x000D_
}_x000D_
_x000D_
.child {_x000D_
  float: left;_x000D_
  background-color: blue;_x000D_
  width: 50px;_x000D_
  height: 50px;_x000D_
}

<div id="container">_x000D_
  <div id="inner">_x000D_
    <div class="child"></div>_x000D_
    <div class="child"></div>_x000D_
    <div class="child"></div>_x000D_
  </div>_x000D_
</div>

I used a bit different Approach, as we always know our actual components so i thought to apply switch case. Also total no of component were around 7-8 in my case.

getSubComponent(name) {
    let customProps = {
       "prop1" :"",
       "prop2":"",
       "prop3":"",
       "prop4":""
    }

    switch (name) {
      case "Component1": return <Component1 {...this.props} {...customProps} />
      case "Component2": return <Component2 {...this.props} {...customProps} />
      case "component3": return <component3 {...this.props} {...customProps} />

    }
  }

Use -B, -A or -C option

grep --help
...
-B, --before-context=NUM  print NUM lines of leading context
-A, --after-context=NUM   print NUM lines of trailing context
-C, --context=NUM         print NUM lines of output context
-NUM                      same as --context=NUM
...

#the_div input {
  margin: 0 auto;
}

I'm not sure if this works in good ol' IE6, so you might have to do this instead.

/* IE 6 (probably) */
#the_div {
  text-align: center;
}

VOLUME is used in Dockerfile to expose the volume to be used by other containers. Example, create Dockerfile as:

FROM ubuntu:14.04

RUN mkdir /myvol  
RUN echo "hello world" > /myvol/greeting  
VOLUME /myvol

build the image:

$ docker build -t testing_volume .

Run the container, say container1:

$ docker run -it <image-id of above image> bash

Now run another container with volumes-from option as (say-container2)

$ docker run -it --volumes-from <id-of-above-container> ubuntu:14.04 bash

You will get all data from container1 /myvol directory into container2 at same location.

-v option is given at run time of container which is used to mount container's directory on host. It is simple to use, just provide -v option with argument as <host-path>:<container-path>. The whole command may be as $ docker run -v <host-path>:<container-path> <image-id>

This will make your edittext disabled.

editText.setEnabled(false);

And by using this

editText.setInputType(InputType.TYPE_NULL);

Will just make your Edittext not show your softkeyboard, but if it is connected to a physical keyboard, it will let you type.

// hide the default back buttons
 self.navigationItem.hidesBackButton = true

Previous answers are correct but here is one more way of doing this and some tips:

Option #1 Go to you Jenkins job and search for "add build step" and then just copy and paste your script there

Option #2 Go to Jenkins and do the same again "add build step" but this time put the fully qualified path for your script in there example : ./usr/somewhere/helloWorld.sh

things to watch for /tips:

• Environment variables, if your job is running at the same time then you need to worry about concurrency issues. One job may be setting the value of environment variables and the next may use the value or take some action based on that incorrectly.
• Make sure all paths are fully qualified
• Think about logging /var/log or somewhere so you would also have something to go to on the server (optional)
• thing about space issue and permissions, running out of space and permission issues are very common in linux environment
• Alerting and make sure your script/job fails the jenkin jobs when your script fails

Another consideration is the number of object files (translation units) that you actually consume in a library vs the total number available. If a library is built from many object files, but you only use symbols from a few of them, this might be an argument for favoring static linking, since you only link the objects that you use when you static link (typically) and don't normally carry the unused symbols. If you go with a shared lib, that lib contains all translation units and could be much larger than what you want or need.

You can also initialise it like this:

struct name sara = { "Sara", "Black" };

Since (as a special case) you're allowed to initialise char arrays from string constants.

Now, as for what a struct actually is - it's a compound type composed of other values. What sara actually looks like in memory is a block of 20 consecutive char values (which can be referred to using sara.first, followed by 0 or more padding bytes, followed by another block of 20 consecutive char values (which can be referred to using sara.last). All other instances of the struct name type are laid out in the same way.

In this case, it is very unlikely that there is any padding, so a struct name is just a block of 40 characters, for which you have a name for the first 20 and the last 20.

You can find out how big a block of memory a struct name takes using sizeof(struct name), and you can find out where within that block of memory each member of the structure is placed at using offsetof(struct name, first) and offsetof(struct name, last).

To add/subtract from a DATE, you have 2 options :

Method #1 : The easiest way is to use + and - to add/subtract days, hours, minutes, seconds, etc.. from a DATE, and ADD_MONTHS() function to add/subtract months and years from a DATE. Why ? That's because from days, you can get hours and any smaller unit (1 hour = 1/24 days), (1 minute = 1/1440 days), etc... But you cannot get months and years, as that depends on the month and year themselves, hence ADD_MONTHS() and no add_years(), because from months, you can get years (1 year = 12 months).

Let's try them :

SELECT TO_CHAR(SYSDATE, 'DD-MON-YYYY HH24:MI:SS')             FROM dual;        -- prints current date:    19-OCT-2019 20:42:02 
SELECT TO_CHAR((SYSDATE + 1/24), 'DD-MON-YYYY HH24:MI:SS')    FROM dual;        -- prints date + 1 hour:   19-OCT-2019 21:42:02
SELECT TO_CHAR((SYSDATE + 1/1440), 'DD-MON-YYYY HH24:MI:SS')  FROM dual;        -- prints date + 1 minute: 19-OCT-2019 20:43:02 
SELECT TO_CHAR((SYSDATE + 1/86400), 'DD-MON-YYYY HH24:MI:SS') FROM dual;        -- prints date + 1 second: 19-OCT-2019 20:42:03 
-- Same goes for subtraction.

SELECT SYSDATE                  FROM dual;       -- prints current date:     19-OCT-19
SELECT ADD_MONTHS(SYSDATE, 1)   FROM dual;       -- prints date + 1 month:   19-NOV-19
SELECT ADD_MONTHS(SYSDATE, 12)  FROM dual;       -- prints date + 1 year:    19-OCT-20
SELECT ADD_MONTHS(SYSDATE, -3)  FROM dual;       -- prints date - 3 months:  19-JUL-19

Method #2 : Using INTERVALs, you can or subtract an interval (duration) from a date easily. More than that, you can combine to add or subtract multiple units at once (e.g 5 hours and 6 minutes, etc..) Examples :

SELECT TO_CHAR(SYSDATE, 'DD-MON-YYYY HH24:MI:SS')                                        FROM dual;        -- prints current date:                 19-OCT-2019 21:34:15
SELECT TO_CHAR((SYSDATE + INTERVAL '1' HOUR), 'DD-MON-YYYY HH24:MI:SS')                  FROM dual;        -- prints date + 1 hour:                19-OCT-2019 22:34:15
SELECT TO_CHAR((SYSDATE + INTERVAL '1' MINUTE), 'DD-MON-YYYY HH24:MI:SS')                FROM dual;        -- prints date + 1 minute:              19-OCT-2019 21:35:15
SELECT TO_CHAR((SYSDATE + INTERVAL '1' SECOND), 'DD-MON-YYYY HH24:MI:SS')                FROM dual;        -- prints date + 1 second:              19-OCT-2019 21:34:16
SELECT TO_CHAR((SYSDATE + INTERVAL '01:05:00' HOUR TO SECOND), 'DD-MON-YYYY HH24:MI:SS') FROM dual;        -- prints date + 1 hour and 5 minutes:  19-OCT-2019 22:39:15
SELECT TO_CHAR((SYSDATE + INTERVAL '3 01' DAY TO HOUR), 'DD-MON-YYYY HH24:MI:SS')        FROM dual;        -- prints date + 3 days and 1 hour:     22-OCT-2019 22:34:15
SELECT TO_CHAR((SYSDATE - INTERVAL '10-3' YEAR TO MONTH), 'DD-MON-YYYY HH24:MI:SS')      FROM dual;        -- prints date - 10 years and 3 months: 19-JUL-2009 21:34:15

Unfortunately, Dictionary has problems with Model Binding in MVC. Read the full story here. Instead, create a custom model binder to get the Dictionary as a parameter for the controller action.

To solve your requirement, here is the working solution -

First create your ViewModels in following way. PersonModel can have list of RoleModels.

public class PersonModel
{
    public List<RoleModel> Roles { get; set; }
    public string Name { get; set; }
}

public class RoleModel
{
    public string RoleName { get; set;}
    public string Description { get; set;}
}

Then have a index action which will be serving basic index view -

public ActionResult Index()
{
    return View();
}

Index view will be having following JQuery AJAX POST operation -

<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script>
    $(function () {
        $('#click1').click(function (e) {

            var jsonObject = {
                "Name" : "Rami",
                "Roles": [{ "RoleName": "Admin", "Description" : "Admin Role"}, { "RoleName": "User", "Description" : "User Role"}]
            };

            $.ajax({
                url: "@Url.Action("AddUser")",
                type: "POST",
                data: JSON.stringify(jsonObject),
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                error: function (response) {
                    alert(response.responseText);
            },
                success: function (response) {
                    alert(response);
                }
            });

        });
    });
</script>

<input type="button" value="click1" id="click1" />

Index action posts to AddUser action -

[HttpPost]
public ActionResult AddUser(PersonModel model)
{
    if (model != null)
    {
        return Json("Success");
    }
    else
    {
        return Json("An Error Has occoured");
    }
}

So now when the post happens you can get all the posted data in the model parameter of action.

Update:

For asp.net core, to get JSON data as your action parameter you should add the [FromBody] attribute before your param name in your controller action. Note: if you're using ASP.NET Core 2.1, you can also use the [ApiController] attribute to automatically infer the [FromBody] binding source for your complex action method parameters. (Doc)

Your issue is with attempting to change your month by adding 1. 1 in date serials in Excel is equal to 1 day. Try changing your month by using the following:

NewDate = Format(DateAdd("m",1,StartDate),"dd/mm/yyyy")

__new__ is static class method, while __init__ is instance method. __new__ has to create the instance first, so __init__ can initialize it. Note that __init__ takes self as parameter. Until you create instance there is no self.

Now, I gather, that you're trying to implement singleton pattern in Python. There are a few ways to do that.

Also, as of Python 2.6, you can use class decorators.

def singleton(cls):
    instances = {}
    def getinstance():
        if cls not in instances:
            instances[cls] = cls()
        return instances[cls]
    return getinstance

@singleton
class MyClass:

This error tells you that you do not have the razor engine properly associated with your project.

Solution: In the Solution Explorer window right click on your web project and select "Manage Nuget Packages..." then install "Microsoft ASP.NET Razor". This will make sure that the properly package is installed and it will add the necessary entries into your web.config file.

You need the following permissions in your manifest file:

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission>

Then you can use the following in your activity class:

WifiManager wifiManager = (WifiManager) this.getApplicationContext().getSystemService(Context.WIFI_SERVICE); 
wifiManager.setWifiEnabled(true);
wifiManager.setWifiEnabled(false);

Use the following to check if it's enabled or not

boolean wifiEnabled = wifiManager.isWifiEnabled()

You'll find a nice tutorial on the subject on this site.

Note that the file:/// scheme does not work on the compact framework, at least it doesn't with 5.0.

You will need to use the following:

string appDir = Path.GetDirectoryName(
    Assembly.GetExecutingAssembly().GetName().CodeBase);
webBrowser1.Url = new Uri(Path.Combine(appDir, @"Documentation\index.html"));

The error message says it all: your connection timed out. This means your request did not get a response within some (default) timeframe. The reasons that no response was received is likely to be one of:

• a) The IP/domain or port is incorrect
• b) The IP/domain or port (i.e service) is down
• c) The IP/domain is taking longer than your default timeout to respond
• d) You have a firewall that is blocking requests or responses on whatever port you are using
• e) You have a firewall that is blocking requests to that particular host
• f) Your internet access is down

Note that firewalls and port or IP blocking may be in place by your ISP

I almost always use the standard formating ShortDateString, because I want the user to be in control of the actual output of the date.

Code

   Dim d As DateTime = Now
   Debug.WriteLine(d.ToLongDateString)
   Debug.WriteLine(d.ToShortDateString)
   Debug.WriteLine(d.ToString("d"))
   Debug.WriteLine(d.ToString("yyyy-MM-dd"))

Instead of using HTML comments (which have no effect on PHP code -- which will still be executed), you should use PHP comments:

<?php /*
<tr>
      <td><?php echo $entry_keyword; ?></td>
      <td><input type="text" name="keyword" value="<?php echo $keyword; ?>" /></td>
    </tr>
    <tr>
      <td><?php echo $entry_sort_order; ?></td>
      <td><input name="sort_order" value="<?php echo $sort_order; ?>" size="1" /></td>
    </tr>
*/ ?>

With that, the PHP code inside the HTML will not be executed; and nothing (not the HTML, not the PHP, not the result of its non-execution) will be displayed.

Just one note: you cannot nest C-style comments... which means the comment will end at the first */ encountered.

The error you are receiving is due to how you define jet. You are creating the base class Colormap with the name 'jet', but this is very different from getting the default definition of the 'jet' colormap. This base class should never be created directly, and only the subclasses should be instantiated.

What you've found with your example is a buggy behavior in Matplotlib. There should be a clearer error message generated when this code is run.

This is an updated version of your example:

import matplotlib.pyplot as plt
import matplotlib.colors as colors
import matplotlib.cm as cmx
import numpy as np

# define some random data that emulates your indeded code:
NCURVES = 10
np.random.seed(101)
curves = [np.random.random(20) for i in range(NCURVES)]
values = range(NCURVES)

fig = plt.figure()
ax = fig.add_subplot(111)
# replace the next line 
#jet = colors.Colormap('jet')
# with
jet = cm = plt.get_cmap('jet') 
cNorm  = colors.Normalize(vmin=0, vmax=values[-1])
scalarMap = cmx.ScalarMappable(norm=cNorm, cmap=jet)
print scalarMap.get_clim()

lines = []
for idx in range(len(curves)):
    line = curves[idx]
    colorVal = scalarMap.to_rgba(values[idx])
    colorText = (
        'color: (%4.2f,%4.2f,%4.2f)'%(colorVal[0],colorVal[1],colorVal[2])
        )
    retLine, = ax.plot(line,
                       color=colorVal,
                       label=colorText)
    lines.append(retLine)
#added this to get the legend to work
handles,labels = ax.get_legend_handles_labels()
ax.legend(handles, labels, loc='upper right')
ax.grid()
plt.show()

Resulting in:

Using a ScalarMappable is an improvement over the approach presented in my related answer: creating over 20 unique legend colors using matplotlib

A performance-driven approach - calling environ is expensive, so it's better to call it once and save it to a dictionary. Full example:

from os import environ


# Slower
print(environ["USER"], environ["NAME"])

# Faster
env_dict = dict(environ)
print(env_dict["USER"], env_dict["NAME"])

P.S- if you worry about exposing private environment variables, then sanitize env_dict after the assignment.

The easy way to convert String to java.sql.Timestamp:

Timestamp t = new Timestamp(DateUtil.provideDateFormat().parse("2019-01-14T12:00:00.000Z").getTime());

DateUtil.java:

import java.text.SimpleDateFormat;
import java.util.TimeZone;

public interface DateUtil {

  String ISO_DATE_FORMAT_ZERO_OFFSET = "yyyy-MM-dd'T'HH:mm:ss.SSS'Z'";
  String UTC_TIMEZONE_NAME = "UTC";

  static SimpleDateFormat provideDateFormat() {
    SimpleDateFormat simpleDateFormat = new SimpleDateFormat(ISO_DATE_FORMAT_ZERO_OFFSET);
    simpleDateFormat.setTimeZone(TimeZone.getTimeZone(UTC_TIMEZONE_NAME));
    return simpleDateFormat;
  }
}

static means that the method is associated with the class, not a specific instance (object) of that class. This means that you can call a static method without creating an object of the class. Because of use of a static keyword main() is your first method to be invoked.. static doesn't need to any object to instance... so,main( ) is called by the Java interpreter before any objects are made.

I also found if your webcam didnt close right or something is using it, then CV2 will give this same error. I had to restart my pc to get it to work again.

I think the simplest way would be

 return new Friend[0];

The requirements of the return are merely that the method return an object which implements IEnumerable<Friend>. The fact that under different circumstances you return two different kinds of objects is irrelevant, as long as both implement IEnumerable.

I've solved it, it can be done executing:

netsh interface portproxy add v4tov4 listenport=4422 listenaddress=192.168.1.111 connectport=80 connectaddress=192.168.0.33

To remove forwarding:

netsh interface portproxy delete v4tov4 listenport=4422 listenaddress=192.168.1.111

Official docs

Why not just have a Year property, which is perfectly fine?

Interfaces don't contain fields because fields represent a specific implementation of data representation, and exposing them would break encapsulation. Thus having an interface with a field would effectively be coding to an implementation instead of an interface, which is a curious paradox for an interface to have!

For instance, part of your Year specification might require that it be invalid for ICar implementers to allow assignment to a Year which is later than the current year + 1 or before 1900. There's no way to say that if you had exposed Year fields -- far better to use properties instead to do the work here.

Here's a couple of suggestions:

Use date_range for the index:

import datetime
import pandas as pd
import numpy as np

todays_date = datetime.datetime.now().date()
index = pd.date_range(todays_date-datetime.timedelta(10), periods=10, freq='D')

columns = ['A','B', 'C']

Note: we could create an empty DataFrame (with NaNs) simply by writing:

df_ = pd.DataFrame(index=index, columns=columns)
df_ = df_.fillna(0) # with 0s rather than NaNs

To do these type of calculations for the data, use a numpy array:

data = np.array([np.arange(10)]*3).T

Hence we can create the DataFrame:

In [10]: df = pd.DataFrame(data, index=index, columns=columns)

In [11]: df
Out[11]: 
            A  B  C
2012-11-29  0  0  0
2012-11-30  1  1  1
2012-12-01  2  2  2
2012-12-02  3  3  3
2012-12-03  4  4  4

def query(id):
    for line in file:
        table = line.split(";")
        if id == int(table[0]):
             yield table
    
    

id = int(input("Enter the ID of the user: "))
for id_, name, city in query(id):
  print("ID: " + id_)
  print("Name: " + name)
  print("City: " + city)
file.close()

Using yield..

This worked for me within an ASP.NET site. To enable validation on some hidden fields use this code

$("form").data("validator").settings.ignore = ":hidden:not(#myitem)";

To enable validation for all elements of form use this one $("form").data("validator").settings.ignore = "";

Note that use them within $(document).ready(function() { })

According to the API for XCUIElement .exists can be used to check if a query exists or not so the following syntax could be useful in some cases!

let app = XCUIApplication()
app.launch()

let label = app.staticTexts["Hello, world!"]
while !label.exists {
    sleep(1)
}

If you are confident that your expectation will be met eventually you could try running this. It should be noted that crashing might be preferable if the wait is too long in which case waitForExpectationsWithTimeout(_,handler:_) from @Joe Masilotti's post should be used.

Yes, in AndroidManifest.xml, declare your Activity like so: <activity ... android:screenOrientation="landscape" .../>

select COUNT(*)
from Monitor as m
    inner join Monitor_Request as mr on mr.Company_ID=m.Company_id
    group by m.Company_id
    having COUNT(m.Monitor_id)>=5

I was having the same problem, I had a ComboBox followed by a ListBox in a StackPanel and the scroll bar for the ListBox was not showing up. I solved this by putting the two in a DockPanel instead. I set the ComboBox DockPanel.Dock="Top" and let the ListBox fill the remaining space.

simply change <div> to <tbody>

<table id="authenticationSetting" style="display: none">
  <tbody id="authenticationOuterIdentityBlock" style="display: none;">
    <tr>
      <td class="orionSummaryHeader">
        <orion:message key="policy.wifi.enterprise.authentication.outeridentitity" />:</td>
      <td class="orionSummaryColumn">
        <orion:textbox id="authenticationOuterIdentity" size="30" />
      </td>
    </tr>
  </tbody>
</table>

I've an object (basically a VO) in Java and I don't know its type. I need to get values which are not null in that object.

Maybe you don't necessary need reflection for that -- here is a plain OO design that might solve your problem:

1. Add an interface Validation which expose a method validate which checks the fields and return whatever is appropriate.
2. Implement the interface and the method for all VO.
3. When you get a VO, even if it's concrete type is unknown, you can typecast it to Validation and check that easily.

I guess that you need the field that are null to display an error message in a generic way, so that should be enough. Let me know if this doesn't work for you for some reason.

How about skipping the particular file while iterating over all the files in the folder! Below code would skip all excel files that start with 'eph'

import glob
import re
for file in glob.glob('*.xlsx'):
    if re.match('eph.*\.xlsx',file):
        continue
    else:
        #do your stuff here
        print(file)

This way you can use more complex regex patterns to include/exclude a particular set of files in a folder.

beginupd.getTime() will give you time in milliseconds since January 1, 1970, 00:00:00 GMT till the time you have specified in Date object

This might work...

from p in db.products
    select new
    {
        Owner = (p.price > 0 ?
            from q in db.Users select q.Name :
            from r in db.ExternalUsers select r.Name)
    }

add a new .css class:

#test.nohover:hover { border: 0 }

and

<div id="test" class="nohover">blah</div>

The more "specific" css rule wins, so this border:0 version will override the generic one specified elsewhere.

This question actually have more deep nature and good understanding of the multithreading concepts in general will provide you insight about this topic. In fact there is no any language or any operating system which provide you facilities for asynchronous abruptly thread termination without warning to not use them. And all these execution environments strongly advise developer or even require build multithreading applications on the base of cooperative or synchronous thread termination. The reason for this common decisions and advices is that all they are built on the base of the same general multithreading model.

Let's compare multiprocessing and multithreading concepts to better understand advantages and limitations of the second one.

Multiprocessing assumes splitting of the entire execution environment into set of completely isolated processes controlled by the operating system. Process incorporates and isolates execution environment state including local memory of the process and data inside it and all system resources like files, sockets, synchronization objects. Isolation is a critically important characteristic of the process, because it limits the faults propagation by the process borders. In other words, no one process can affects the consistency of any another process in the system. The same is true for the process behaviour but in the less restricted and more blur way. In such environment any process can be killed in any "arbitrary" moment, because firstly each process is isolated, secondly, operating system have full knowledges about all resources used by process and can release all of them without leaking, and finally process will be killed by OS not really in arbitrary moment, but in the number of well defined points where the state of the process is well known.

In contrast, multithreading assumes running multiple threads in the same process. But all this threads are share the same isolation box and there is no any operating system control of the internal state of the process. As a result any thread is able to change global process state as well as corrupt it. At the same moment the points in which the state of the thread is well known to be safe to kill a thread completely depends on the application logic and are not known neither for operating system nor for programming language runtime. As a result thread termination at the arbitrary moment means killing it at arbitrary point of its execution path and can easily lead to the process-wide data corruption, memory and handles leakage, threads leakage and spinlocks and other intra-process synchronization primitives leaved in the closed state preventing other threads in doing progress.

Due to this the common approach is to force developers to implement synchronous or cooperative thread termination, where the one thread can request other thread termination and other thread in well-defined point can check this request and start the shutdown procedure from the well-defined state with releasing of all global system-wide resources and local process-wide resources in the safe and consistent way.

You can try Context.getApplicationInfo().dataDir if you want the package's persistent data folder.

getFilesDir() returns a subroot of this.

I wouldn't use JavaScript navigator.userAgent or $.browser (which uses navigator.userAgent) since it can be spoofed.

For people who find this old posting on the web by searching for the error message, there is another possible cause of the problem.

You could just have a typo in your call to the script, even if you have already done the things described in the other excellent answer. So check to make sure you can used the right spelling in your script tags.

You can use DataView.

DataView dv = new DataView(yourDatatable);
dv.RowFilter = "query"; // query example = "id = 10"

http://www.csharp-examples.net/dataview-rowfilter/

Update

Below you've said:

Sorry, i can't predict date format before, it should be like dd-mm-yyyy or dd/mm/yyyy or dd-mmm-yyyy format finally i wanted to convert all this format to dd-MMM-yyyy format.

That completely changes the question. It'll be much more complex if you can't control the format. There is nothing built into JavaScript that will let you specify a date format. Officially, the only date format supported by JavaScript is a simplified version of ISO-8601: yyyy-mm-dd, although in practice almost all browsers also support yyyy/mm/dd as well. But other than that, you have to write the code yourself or (and this makes much more sense) use a good library. I'd probably use a library like moment.js or DateJS (although DateJS hasn't been maintained in years).

Original answer:

If the format is always dd/mm/yyyy, then this is trivial:

var parts = str.split("/");
var dt = new Date(parseInt(parts[2], 10),
                  parseInt(parts[1], 10) - 1,
                  parseInt(parts[0], 10));

split splits a string on the given delimiter. Then we use parseInt to convert the strings into numbers, and we use the new Date constructor to build a Date from those parts: The third part will be the year, the second part the month, and the first part the day. Date uses zero-based month numbers, and so we have to subtract one from the month number.

This what I did to show the confirmation message just when I have unsaved data

window.onbeforeunload = function () {
            if (isDirty) {
                return "There are unsaved data.";
            }
            return undefined;
        }

returning "undefined" will disable the confirmation

Note: returning "null" will not work with IE

Also you can use "undefined" to disable the confirmation

window.onbeforeunload = undefined;

This works on my Mac OS:

for n in `ipcs -b -m | egrep ^m | awk '{ print $2; }'`; do ipcrm -m $n; done

For me, the problem occurs when I've downloaded macOS Compressed Archive which underlying directory contains

jdk-11.0.8.jdk
- Contents
  - Home
    - bin
    - ...
  - MacOS
  - _CodeSignature

So, to solve the problem, JAVA_HOME should be pointed directly to /Path-to-JDK/Contents/Home.

If you have more than one element with the same ID, then you have invalid HTML.

But you can acheive the same result using classes instead. That's what they're designed for.

<input class='b' ... >

You can give it an ID as well if you need to, but it should be unique.

Once you've got the class in there, you can reference it with a dot instead of the hash, like so:

var value = $('#a .b').val();

or

var value = $('#a input.b').val();

which will limit it to 'b' class elements that are inputs within the form (which seems to be close to what you're asking for).

You need to use strcmp:

strcmp(namet2, nameIt2)

Thanks to Stack user over this explanation, I've got this working even on Android 4.1.1

((View)myView.getParent()).requestLayout();
myView.bringToFront();

On my dynamic use, for example, I did

public void onMyClick(View v)
     {
     ((View)v.getParent()).requestLayout();
     v.bringToFront();
     }

And Bamm !

I received a similar error and now have it working.

First make sure you have the latest version

brew update

Remove your previous instance of node:

brew uninstall node

Then reinstall the latest version:

brew install node

And then make sure it is symlinked into /usr/local if it isn't already. You would get an error to let you know to complete this step.

brew link --overwrite node 

More details on how to install/upgrade node are also available.

Be aware that HttpOnly doesn't stop cross-site scripting; instead, it neutralizes one possible attack, and currently does that only on IE (FireFox exposes HttpOnly cookies in XmlHttpRequest, and Safari doesn't honor it at all). By all means, turn HttpOnly on, but don't drop even an hour of output filtering and fuzz testing in trade for it.

The existing answers show a possible solution for single files or file types. However, you can define the charset standard in VS Code by following this path:

File > Preferences > Settings > Encoding > Choose your option

This will define a character set as default. Besides that, you can always change the encoding in the lower right corner of the editor (blue symbol line) for the current project.

You can use the IFNULL function inside the IF. This will be a little shorter, and there will be fewer repetitions of the field name.

SELECT IF(IFNULL(field1, '') = '', 'empty', field1) AS field1 
FROM tablename

For greater than 24 hours you can include days with the following query. The returned format is days:hh24:mi:ss

Query:
select trunc(trunc(sysdate) + numtodsinterval(9999999, 'second')) - trunc(sysdate) || ':' || to_char(trunc(sysdate) + numtodsinterval(9999999, 'second'), 'hh24:mi:ss') from dual;

Output:
115:17:46:39

You could have them semi-colon delimited in a single value, e.g.

App.config

<add key="paths" value="C:\test1;C:\test2;C:\test3" />

C#

var paths = new List<string>(ConfigurationManager.AppSettings["paths"].Split(new char[] { ';' }));

tl;dr

OffsetDateTime.parse( "2010-03-01T00:00:00-08:00" )

Details

The answer by BalusC is correct, but now outdated as of Java 8.

java.time

The java.time framework is the successor to both Joda-Time library and the old troublesome date-time classes bundled with the earliest versions of Java (java.util.Date/.Calendar & java.text.SimpleDateFormat).

ISO 8601

Your input data string happens to comply with the ISO 8601 standard.

The java.time classes use ISO 8601 formats by default when parsing/generating textual representations of date-time values. So no need to define a formatting pattern.

OffsetDateTime

The OffsetDateTime class represents a moment on the time line adjusted to some particular offset-from-UTC. In your input, the offset is 8 hours behind UTC, commonly used on much of the west coast of North America.

OffsetDateTime odt = OffsetDateTime.parse( "2010-03-01T00:00:00-08:00" );

You seem to want the date-only, in which case use the LocalDate class. But keep in mind you are discarding data, (a) time-of-day, and (b) the time zone. Really, a date has no meaning without the context of a time zone. For any given moment the date varies around the world. For example, just after midnight in Paris is still “yesterday” in Montréal. So while I suggest sticking with date-time values, you can easily convert to a LocalDate if you insist.

LocalDate localDate = odt.toLocalDate();

Time Zone

If you know the intended time zone, apply it. A time zone is an offset plus the rules to use for handling anomalies such as Daylight Saving Time (DST). Applying a ZoneId gets us a ZonedDateTime object.

ZoneId zoneId = ZoneId.of( "America/Los_Angeles" );
ZonedDateTime zdt = odt.atZoneSameInstant( zoneId );

Generating strings

To generate a string in ISO 8601 format, call toString.

String output = odt.toString();

If you need strings in other formats, search Stack Overflow for use of the java.util.format package.

Converting to java.util.Date

Best to avoid java.util.Date, but if you must, you can convert. Call the new methods added to the old classes such as java.util.Date.from where you pass an Instant. An Instant is a moment on the timeline in UTC. We can extract an Instant from our OffsetDateTime.

java.util.Date utilDate = java.util.Date( odt.toInstant() );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

You asked for elegancy, and I created a simple class to also support a lazy check (which has an idle state), aside to the imperative way (with callbacks). In addition, this class supports "backToActive" when the idle time is violated.

class Idle {
    constructor(timeout = 10, idleCallback = null, backToActiveCallback = null, autoStart = true, backToActiveOnXHR = false) {
        this.timeout = timeout
        this.idleCallback = idleCallback
        this.backToActiveCallback = backToActiveCallback
        this.autoStart = autoStart // only F5
        this.backToActiveOnXHR = backToActiveOnXHR
        this.idle = false
        this.timer = null
        this.events = ['scroll', 'mousedown', 'mousemove', 'keypress', 'scroll', 'touchstart']
        this.init()
    }

    init() {
        if(this.backToActiveOnXHR) {
            this.events.push('load')
        }
        this.events.forEach(name => {
            window.addEventListener(name, this.backToActive, true)
        })
        if(this.autoStart) {
            this.backToActive()
        }
    }

    goIdle = () => {
        this.idle = true
        if(!!this.idleCallback) {
            this.idleCallback(this.timeout)
        }
    }

    backToActive = () => {
        if(this.idle) {
            this.backToActiveCallback()
        }
        this.idle = false
        clearTimeout(this.timer)
        this.timer = setTimeout(this.goIdle, this.timeout * 1000)
    }
}

Usage:

let idleCallback = timeout => { console.log(`Went idle after ${timeout} seconds`) }
let backToActiveCallback = () => { console.log('Back to active') }
let idle = new Idle(30, idleCallback, backToActiveCallback)

Result in devtools:

// Went idle after 30 seconds <--- goes idle when no activity is detected
// Back to active <--- when the user is detected again

The advantage of supporting laziness:

setInterval(() => {
    common.fetchApi('/api/v1/list', { status: idle.idle ? 'away' : 'online' }).then(/* show a list of elements */)
}, 1000 * 5)

Why would you want a lazy check? Sometimes we use a periodic XHR (with setInterval), i.e. when a user watch a list of flights, rides, movies, orders etc. With each XHR we then can add information about his activity status (online / away), so we have a sense of active users in our system.

My class is based on Equiman's & Frank Conijn's answers.

You could try to set title to null.

This worked for me.

If you just want to open the Google Chrome from terminal instantly for once then open -a "Google Chrome" works fine from Mac Terminal.

If you want to use an alias to call Chrome from terminal then you need to edit the bash profile and add an alias on ~/.bash_profile or ~/.zshrc file.The steps are below :

• Edit ~/.bash_profile or ~/.zshrc file and add the following line alias chrome="open -a 'Google Chrome'"
• Save and close the file.
• Logout and relaunch Terminal
• Type chrome filename for opening a local file.
• Type chrome url for opening url.

I have follow @Michael's answer and it works.

I do it as UserControl where I can drag and drop like a Controls elements. I use MaterialDesign Theme from Nuget to get the Chevron icon and button ripple effect.

On MyPageDesign.xaml, drag and drop created usercontrol will having <UserControlTemplate:TemplateNumericUpDown HorizontalAlignment="Left" Height="100" VerticalAlignment="Top" Width="100"/>

To get the value from the template, I use

string Value1 = JournalNumStart.NumValue;
string Value2 = JournalNumEnd.NumValue;

I'm not in good skill yet to binding the Height of the control based from FontSize element, so I set the from my page fontsize manually in usercontrol.

The command line arguments are separated by space. If you want provide an argument with a space in it, you should quote it. So use git commit -m "initial commit".

.sr-only is a class name specifically used for screen readers. You can use any class name, but .sr-only is pretty commonly used. If you don't care about developing with compliance in mind, then it can be removed. It will not affect UI in any way if removed because the CSS for this class is not visible to desktop and mobile device browsers.

There seems to be some information missing here about the use of .sr-only to explain its purpose and being for screen readers. First and foremost, it is very important to always keep impaired users in mind. Impairment is the purpose of 508 compliance: https://www.section508.gov/, and it is great that bootstrap takes this into consideration. However, the use of .sr-only is not all that needs to be taken into consideration for 508 compliance. You have the use of color, size of fonts, accessibility via navigation, descriptors, use of aria and so much more.

But as for .sr-only - what does the CSS actually do? There are several slightly different variants of the CSS used for .sr-only. One of the few I use is below:

.sr-only {
    position: absolute;
    margin: -1px 0 0 -1px;
    padding: 0;
    display: block;
    width: 1px;
    height: 1px;
    font-size: 1px;
    line-height: 1px;
    overflow: hidden;
    clip: rect(0,0,0,0);
    border: 0;
    outline: 0;
    }

The above CSS hides content in desktop and mobile browsers wrapped with this class, but is seen by a screen reader like JAWS: http://www.freedomscientific.com/Products/Blindness/JAWS. Example markup is as follows:

<a href="#" target="_blank">
    Click to Open Site
    <span class="sr-only">This is an external link</span>
</a>

Additionally, if a DOM element has a width and height of 0, the element is not seen by the DOM. This is why the above CSS uses width: 1px; height: 1px;. By using display: none and setting your CSS to height: 0 and width: 0, the element is not seen by the DOM and is thus problematic. The above CSS using width: 1px; height: 1px; is not all you do to make the content invisible to desktop and mobile browsers (without overflow: hidden, your content would still show on the screen), and visible to screen readers. Hiding the content from desktop and mobile browsers is done by adding an offset from width: 1px and height: 1px previously mentioned by using:

position: absolute;
margin: -1px 0 0 -1px; 
overflow: hidden;

Lastly, to have a very good idea of what a screen reader sees and relays to its impaired user, turn off page styling for your browser. For Firefox, you can do this by going to:

View > Page Style > No Style

I hope the information I provided here is of further use to someone in addition to the other responses.

The following is the more generic solution. It essentially does the same thing (in O(N) order) but on any IEnumberable types and can mixed with types whose property selectors could return null.

When working with multiple people, it's sometimes difficult to know exactly what's happening. Using a format string instead of concatenation can avoid one particular annoyance that's happened a whole ton of times to us:

Say, a function requires an argument, and you write it expecting to get a string:

In [1]: def foo(zeta):
   ...:     print 'bar: ' + zeta

In [2]: foo('bang')
bar: bang

So, this function may be used pretty often throughout the code. Your coworkers may know exactly what it does, but not necessarily be fully up-to-speed on the internals, and may not know that the function expects a string. And so they may end up with this:

In [3]: foo(23)
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

/home/izkata/<ipython console> in <module>()

/home/izkata/<ipython console> in foo(zeta)

TypeError: cannot concatenate 'str' and 'int' objects

There would be no problem if you just used a format string:

In [1]: def foo(zeta):
   ...:     print 'bar: %s' % zeta
   ...:     
   ...:     

In [2]: foo('bang')
bar: bang

In [3]: foo(23)
bar: 23

The same is true for all types of objects that define __str__, which may be passed in as well:

In [1]: from datetime import date

In [2]: zeta = date(2012, 4, 15)

In [3]: print 'bar: ' + zeta
---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)

/home/izkata/<ipython console> in <module>()

TypeError: cannot concatenate 'str' and 'datetime.date' objects

In [4]: print 'bar: %s' % zeta
bar: 2012-04-15

So yes: If you can use a format string do it and take advantage of what Python has to offer.

Service references are another example where partial classes are useful to separate generated code from user-created code.

You can "extend" the service classes without having them overwritten when you update the service reference.

In CSS2.1, an element can only have at most one of any kind of pseudo-element at any time. (This means an element can have both a :before and an :after pseudo-element — it just cannot have more than one of each kind.)

As a result, when you have multiple :before rules matching the same element, they will all cascade and apply to a single :before pseudo-element, as with a normal element. In your example, the end result looks like this:

.circle.now:before {
    content: "Now";
    font-size: 19px;
    color: black;
}

As you can see, only the content declaration that has highest precedence (as mentioned, the one that comes last) will take effect — the rest of the declarations are discarded, as is the case with any other CSS property.

This behavior is described in the Selectors section of CSS2.1:

Pseudo-elements behave just like real elements in CSS with the exceptions described below and elsewhere.

This implies that selectors with pseudo-elements work just like selectors for normal elements. It also means the cascade should work the same way. Strangely, CSS2.1 appears to be the only reference; neither css3-selectors nor css3-cascade mention this at all, and it remains to be seen whether it will be clarified in a future specification.

If an element can match more than one selector with the same pseudo-element, and you want all of them to apply somehow, you will need to create additional CSS rules with combined selectors so that you can specify exactly what the browser should do in those cases. I can't provide a complete example including the content property here, since it's not clear for instance whether the symbol or the text should come first. But the selector you need for this combined rule is either .circle.now:before or .now.circle:before — whichever selector you choose is personal preference as both selectors are equivalent, it's only the value of the content property that you will need to define yourself.

If you still need a concrete example, see my answer to this similar question.

The legacy css3-content specification contains a section on inserting multiple ::before and ::after pseudo-elements using a notation that's compatible with the CSS2.1 cascade, but note that that particular document is obsolete — it hasn't been updated since 2003, and no one has implemented that feature in the past decade. The good news is that the abandoned document is actively undergoing a rewrite in the guise of css-content-3 and css-pseudo-4. The bad news is that the multiple pseudo-elements feature is nowhere to be found in either specification, presumably owing, again, to lack of implementer interest.

grep -r -e string directory

-r is for recursive; -e is optional but its argument specifies the regex to search for. Interestingly, POSIX grep is not required to support -r (or -R), but I'm practically certain that System V grep did, so in practice they (almost) all do. Some versions of grep support -R as well as (or conceivably instead of) -r; AFAICT, it means the same thing.

Comparison of different methods

I found other methods to check if a point is inside a polygon (here). I tested two of them only (is_inside_sm and is_inside_postgis) and the results were the same as the other methods.

Thanks to @epifanio, I parallelized the codes and compared them with @epifanio and @user3274748 (ray_tracing_numpy) methods. Note that both methods had a bug so I fixed them as shown in their codes below.

One more thing that I found is that the code provided for creating a polygon does not generate a closed path np.linspace(0,2*np.pi,lenpoly)[:-1]. As a result, the codes provided in above GitHub repository may not work properly. So It's better to create a closed path (first and last points should be the same).

Complete snippet would look like the following. It expands @mouad's answer to asserting on error's message (or generally str representation of its args), which may be useful.
