I think we're over analyzing and maybe complicating a bit the "continuous" suite of words. In this context continuous means automation. For the other words attached to "continuous" use the English language as your translation guide and please don't try to complicate things! In "continuous build" we automatically build (write/compile/link/etc) our application into something that's executable for a specific platform/container/runtime/etc. "Continuous integration" means that your new functionality tests and performs as intended when interacting with another entity. Obviously, before integration takes place, the build must happen and thorough testing would also be used to validate the integration. So, in "continuous integration" one uses automation to add value to an existing bucket of functionality in a way that doesn't negatively disrupt the existing functionality but rather integrates nicely with it, adding a perceived value to the whole. Integration implies, by its mere English definition, that things jive harmoniously so in code-talk my add compiles, links, tests and runs perfectly within the whole. You wouldn't call something integrated if it failed the end product, would you?! In our context "Continuous deployment" is synonymous with "continuos delivery" since at the end of the day we've provided functionality to our customers. However, by over analyzing this, I could argue that deploy is a subset of delivery because deploying something doesn't necessarily mean that we delivered. We deployed the code but because we haven't effectively communicated to our stakeholders, we failed to deliver from a business perspective! We deployed the troops but we haven't delivered the promised water and food to the nearby town. What if I were to add the "continuous transition" term, would it have its own merit? After all, maybe it's better suited to describe the movement of code through environments since it has the connotation of "from/to" more so than deployment or delivery which could imply one location only, in perpetuity! This is what we get if we don't apply common sense.

In conclusion, this is simple stuff to describe (doing it is a bit more ...complicated!), just use common sense, the English language and you'll be fine.

For me the easiest way was to read the last versions of the project with a combination of curl, grep, sort and tail.

My format: service-(version: 1.9.23)-(buildnumber)156.tar.gz

versionToDownload=$(curl -u$user:$password 'https://$artifactory/artifactory/$project/' | grep -o 'service-[^"]*.tar.gz' | sort | tail -1)

To add to this question, I found out that you don't have to use the /buildWithParameters endpoint.

In my scenario, I have a script that triggers Jenkins to run tests after a deployment. Some of these tests require extra info about the deployment to work correctly.

If I tried to use /buildWithParameters on a job that does not expect parameters, the job would not run. I don't want to go in and edit every job to require fake parameters just to get the jobs to run.

Instead, I found you can pass parameters like this:

curl -X POST --data-urlencode "token=${TOKEN}" --data-urlencode json='{"parameter": [{"name": "myParam", "value": "TEST"}]}' https://jenkins.corp/job/$JENKINS_JOB/build

With this json=... it will pass the param myParam with value TEST to the job whenever the call is made. However, the Jenkins job will still run even if it is not expecting the parameter myParam.

The only scenario this does not cover is if the job has a parameter that is NOT passed in the json. Even if the job has a default value set for the parameter, it will fail to run the job. In this scenario you will run into the following error message / stack trace when you call /build:

java.lang.IllegalArgumentException: No such parameter definition: myParam

I realize that this answer is several years late, but I hope this may be useful info for someone else!

Note: I am using Jenkins v2.163

EDIT: While this is currently accepted answer, readers might find this other answer by user John Hart more adapted to their needs. It uses an option which, according to user Ken, was introduced in version 7.21.3 (which was released in December 2010, i.e. after this initial answer).

In your edited question, you're using the URL as the host name, whereas it needs to be the host name only.

Try:

curl -H 'Host: project1.loc' http://127.0.0.1/something

where project1.loc is just the host name and 127.0.0.1 is the target IP address.

(If you're using curl from a library and not on the command line, make sure you don't put http:// in the Host header.)

NB-I removed FromURI .Still I can pass value from URL and get result.If anyone knows benfifts using fromuri let me know

Here is my rendition....

function get_time_difference(earlierDate, laterDate) 
{
    var oDiff = new Object();

    //  Calculate Differences
    //  -------------------------------------------------------------------  //
    var nTotalDiff = laterDate.getTime() - earlierDate.getTime();

    oDiff.days = Math.floor(nTotalDiff / 1000 / 60 / 60 / 24);
    nTotalDiff -= oDiff.days * 1000 * 60 * 60 * 24;

    oDiff.hours = Math.floor(nTotalDiff / 1000 / 60 / 60);
    nTotalDiff -= oDiff.hours * 1000 * 60 * 60;

    oDiff.minutes = Math.floor(nTotalDiff / 1000 / 60);
    nTotalDiff -= oDiff.minutes * 1000 * 60;

    oDiff.seconds = Math.floor(nTotalDiff / 1000);
    //  -------------------------------------------------------------------  //

    //  Format Duration
    //  -------------------------------------------------------------------  //
    //  Format Hours
    var hourtext = '00';
    if (oDiff.days > 0){ hourtext = String(oDiff.days);}
    if (hourtext.length == 1){hourtext = '0' + hourtext};

    //  Format Minutes
    var mintext = '00';
    if (oDiff.minutes > 0){ mintext = String(oDiff.minutes);}
    if (mintext.length == 1) { mintext = '0' + mintext };

    //  Format Seconds
    var sectext = '00';
    if (oDiff.seconds > 0) { sectext = String(oDiff.seconds); }
    if (sectext.length == 1) { sectext = '0' + sectext };

    //  Set Duration
    var sDuration = hourtext + ':' + mintext + ':' + sectext;
    oDiff.duration = sDuration;
    //  -------------------------------------------------------------------  //

    return oDiff;
}

When using a factory your code is still actually responsible for creating objects. By DI you outsource that responsibility to another class or a framework, which is separate from your code.

The correct value for the content attribute should include initial-scale instead:

<meta name="viewport" content="width=device-width, initial-scale=1">_x000D_
                                                   ^^^^^^^^^^^^^^^

Add the runat="server" attribute to the tag, then you can reference it from the codebehind.

You need to call $compile on the HTML string before inserting it into the DOM so that angular gets a chance to perform the binding.

In your fiddle, it would look something like this.

$("#dynamicContent").html(
  $compile(
    "<button ng-click='count = count + 1' ng-init='count=0'>Increment</button><span>count: {{count}} </span>"
  )(scope)
);

Obviously, $compile must be injected into your controller for this to work.

Read more in the $compile documentation.

The main difference is when compiled in debug mode, pdb files are also created which allow debugging (so you can step through the code when its running). This however means that the code isn't optimized as much.

This is how I solved the problem:

@{int proID = 123; int nonProID = 456;}

<script type="text/javascript">
var nonID = Number(@nonProID);
var proID = Number(@proID);
</script>

It is self-documenting and it doesn't involve conversion to and from text.

Note: be careful to use the Number() function not create new Number() objects - as the exactly equals operator may behave in a non-obvious way:

var y = new Number(123); // Note incorrect usage of "new"
var x = new Number(123);
alert(y === 123); // displays false
alert(x == y); // displays false

It took me a lot of time to figure out, but finally here is a simple way to list contents of a subfolder in S3 bucket using boto3. Hope it helps

prefix = "folderone/foldertwo/"
s3 = boto3.resource('s3')
bucket = s3.Bucket(name="bucket_name_here")
FilesNotFound = True
for obj in bucket.objects.filter(Prefix=prefix):
     print('{0}:{1}'.format(bucket.name, obj.key))
     FilesNotFound = False
if FilesNotFound:
     print("ALERT", "No file in {0}/{1}".format(bucket, prefix))

If you want to concatenate the fields using / as a separator, you can use concat_ws:

select concat_ws('/', col1, col2, col3) from mytable

You cannot escape listing the columns in the query though. The *-syntax works only in "select * from". You can list the columns and construct the query dynamically though.

If you are using PHP, try calling htmlentities or htmlspecialchars function.

Look out for stateful sets as well

kubectl get sts --all-namespaces

to delete all the stateful sets in a namespace

kubectl --namespace <yournamespace> delete sts --all

to delete them one by one

kubectl --namespace ag1 delete sts mssql1 
kubectl --namespace ag1 delete sts mssql2
kubectl --namespace ag1 delete sts mssql3

ah homework...

So wait, you need to deduct the balance of items in stock from the total number of those items that have been ordered? I have to tell you that sounds a bit backwards. Generally I think people do it the other way round. Deduct the total number of items ordered from the balance.

If you really need to do that though... Assuming that ITEM is unique in stock_bal...

SELECT s.ITEM, SUM(m.QTY) - s.QTY AS result
FROM stock_bal s
INNER JOIN master_table m ON m.ITEM = s.ITEM
GROUP BY s.ITEM, s.QTY

getline(fin, buffer, '\n')
where fin is opened file(ifstream object) and buffer is of string/char type where you want to copy line.

UltraID3Lib...

Be aware that UltraID3Lib is no longer officially available, and thus no longer maintained. See comments below for the link to a Github project that includes this library

//using HundredMilesSoftware.UltraID3Lib;
UltraID3 u = new UltraID3();
u.Read(@"C:\mp3\song.mp3");
//view
Console.WriteLine(u.Artist);
//edit
u.Artist = "New Artist";
u.Write();

No need for a library. jQuery used this script for a while, btw.

The code of JS20'07'11 is really incredible simple and direct. One suggestion that I would like to give is to put a exclamation mark in the conditions:

InStr(1, objName.RefersTo, sWsName+"!", vbTextCompare)

Because this will prevent adding a NamedRange in an incorrect Sheet. Eg: If the NamedRange refers to a Sheet named Plan11 and you have another Sheet named Plan1 the code can do some mess when add the ranges if you don't use the exclamation mark.

UPDATE

A correction: It's best to use a regular expression evaluate the name of the Sheet. A simple function that you can use is the following (adapted by http://blog.malcolmp.com/2010/regular-expressions-excel-add-in, enable Microsoft VBScript Regular Expressions 5.5):

Function xMatch(pattern As String, searchText As String, Optional matchIndex As Integer = 1, Optional ignoreCase As Boolean = True) As String
On Error Resume Next
Dim RegEx As New RegExp
RegEx.Global = True
RegEx.MultiLine = True
RegEx.pattern = pattern
RegEx.ignoreCase = ignoreCase
Dim matches As MatchCollection
Set matches = RegEx.Execute(searchText)
Dim i As Integer
i = 1
For Each Match In matches
    If i = matchIndex Then
        xMatch = Match.Value
    End If
    i = i + 1
Next
End Function

So, You can use something like that:

xMatch("'?" +sWsName + "'?" + "!", objName.RefersTo, 1) <> ""

instead of

InStr(1, objName.RefersTo, sWsName+"!", vbTextCompare)

This will cover Plan1 and 'Plan1' (when the range refers to more than one cell) variations

TIP: Avoid Sheet names with single quotes ('), :) .

In CSS3 you could use

height: calc(100% - 60px);

Select-Object returns a custom PSObject with just the properties specified. Even with a single property, you don't get the ACTUAL variable; it is wrapped inside the PSObject.

Instead, do:

Get-Date | Select-Object -ExpandProperty DayOfWeek

That will get you the same result as:

(Get-Date).DayOfWeek

The difference is that if Get-Date returns multiple objects, the pipeline way works better than the parenthetical way as (Get-ChildItem), for example, is an array of items. This has changed in PowerShell v3 and (Get-ChildItem).FullPath works as expected and returns an array of just the full paths.

If you know your way around Java, you can use SvnKit to do browse, search and God knows what with your Subversion server.

After that, you can package your program and invoke it either via an Ant task or a shell script.

It's quite a "brute force" solution, but once you master SvnKit, you can really do lots of cool things.

I have the same error and it fixed it including in the file the following

#include <stdint.h>

at the beginning of your file.

Basically the scope of workspace(s) is divided in two points.

First point (and primary) is the eclipse it self and is related with the settings and metadata configurations (plugin ctr). Each time you create a project, eclipse collects all the configurations and stores them on that workspace and if somehow in the same workspace a conflicting project is present you might loose some functionality or even stability of eclipse it self.

And second (secondary) the point of development strategy one can adopt. Once the primary scope is met (and mastered) and there's need for further adjustments regarding project relations (as libraries, perspectives ctr) then initiate separate workspace(s) could be appropriate based on development habits or possible language/frameworks "behaviors". DLTK for examples is a beast that should be contained in a separate cage. Lots of complains at forums for it stopped working (properly or not at all) and suggested solution was to clean the settings of the equivalent plugin from the current workspace.

Personally, I found myself lean more to language distinction when it comes to separate workspaces which is relevant to known issues that comes with the current state of the plugins are used. Preferably I keep them in the minimum numbers as this is leads to less frustration when the projects are become... plenty and version control is not the only version you keep your projects. Finally, loading speed and performance is an issue that might come up if lots of (unnecessary) plugins are loaded due to presents of irrelevant projects. Bottom line; there is no one solution to every one, no master blue print that solves the issue. It's something that grows with experience, Less is more though!

Let's say for instance you want to get a list of all your customers:

var customers = context.Customers.ToList();

And let's assume that each Customer object has a reference to its set of Orders, and that each Order has references to LineItems which may also reference a Product.

As you can see, selecting a top-level object with many related entities could result in a query that needs to pull in data from many sources. As a performance measure, Include() allows you to indicate which related entities should be read from the database as part of the same query.

Using the same example, this might bring in all of the related order headers, but none of the other records:

var customersWithOrderDetail = context.Customers.Include("Orders").ToList();

As a final point since you asked for SQL, the first statement without Include() could generate a simple statement:

SELECT * FROM Customers;

The final statement which calls Include("Orders") may look like this:

SELECT *
FROM Customers JOIN Orders ON Customers.Id = Orders.CustomerId;

Use RxJS in a Service

What about in a situation where you have a Service that's holding state for example. How could I push changes to that Service, and other random components on the page be aware of such a change? Been struggling with tackling this problem lately

Build a service with RxJS Extensions for Angular.

<script src="//unpkg.com/angular/angular.js"></script>
<script src="//unpkg.com/rx/dist/rx.all.js"></script>
<script src="//unpkg.com/rx-angular/dist/rx.angular.js"></script>

var app = angular.module('myApp', ['rx']);

app.factory("DataService", function(rx) {
  var subject = new rx.Subject(); 
  var data = "Initial";

  return {
      set: function set(d){
        data = d;
        subject.onNext(d);
      },
      get: function get() {
        return data;
      },
      subscribe: function (o) {
         return subject.subscribe(o);
      }
  };
});

Then simply subscribe to the changes.

app.controller('displayCtrl', function(DataService) {
  var $ctrl = this;

  $ctrl.data = DataService.get();
  var subscription = DataService.subscribe(function onNext(d) {
      $ctrl.data = d;
  });

  this.$onDestroy = function() {
      subscription.dispose();
  };
});

Clients can subscribe to changes with DataService.subscribe and producers can push changes with DataService.set.

The DEMO on PLNKR.

You can make a directory "fonts" in a root of your project and put your fonts (sans_serif.ttf) file there. Then you can make something like this:

fonts_path = os.path.join(os.path.dirname(os.path.dirname(__file__)), 'fonts')
font = ImageFont.truetype(os.path.join(fonts_path, 'sans_serif.ttf'), 24)

Try this http://ionicframework.com/docs/api/service/$ionicScrollDelegate/

It does scroll to the top of the list scrollTop()

For Binary Search, T(N) = T(N/2) + O(1) // the recurrence relation

Apply Masters Theorem for computing Run time complexity of recurrence relations : T(N) = aT(N/b) + f(N)

Here, a = 1, b = 2 => log (a base b) = 1

also, here f(N) = n^c log^k(n) //k = 0 & c = log (a base b)

So, T(N) = O(N^c log^(k+1)N) = O(log(N))

Addition: SQL Server 2012 shows some improved performance in this area but doesn't seem to tackle the specific issues noted below. This should apparently be fixed in the next major version after SQL Server 2012!

Your plan shows the single inserts are using parameterised procedures (possibly auto parameterised) so parse/compile time for these should be minimal.

I thought I'd look into this a bit more though so set up a loop (script) and tried adjusting the number of VALUES clauses and recording the compile time.

I then divided the compile time by the number of rows to get the average compile time per clause. The results are below

Up until 250 VALUES clauses present the compile time / number of clauses has a slight upward trend but nothing too dramatic.

But then there is a sudden change.

That section of the data is shown below.

The cached plan size which had been growing linearly suddenly drops but CompileTime increases 7 fold and CompileMemory shoots up. This is the cut off point between the plan being an auto parametrized one (with 1,000 parameters) to a non parametrized one. Thereafter it seems to get linearly less efficient (in terms of number of value clauses processed in a given time).

Not sure why this should be. Presumably when it is compiling a plan for specific literal values it must perform some activity that does not scale linearly (such as sorting).

It doesn't seem to affect the size of the cached query plan when I tried a query consisting entirely of duplicate rows and neither affects the order of the output of the table of the constants (and as you are inserting into a heap time spent sorting would be pointless anyway even if it did).

Moreover if a clustered index is added to the table the plan still shows an explicit sort step so it doesn't seem to be sorting at compile time to avoid a sort at run time.

I tried to look at this in a debugger but the public symbols for my version of SQL Server 2008 don't seem to be available so instead I had to look at the equivalent UNION ALL construction in SQL Server 2005.

So going off the names in the stack trace it appears to spend a lot of time comparing strings.

This KB article indicates that DeriveNormalizedGroupProperties is associated with what used to be called the normalization stage of query processing

This stage is now called binding or algebrizing and it takes the expression parse tree output from the previous parse stage and outputs an algebrized expression tree (query processor tree) to go forward to optimization (trivial plan optimization in this case) [ref].

I tried one more experiment (Script) which was to re-run the original test but looking at three different cases.

1. First Name and Last Name Strings of length 10 characters with no duplicates.
2. First Name and Last Name Strings of length 50 characters with no duplicates.
3. First Name and Last Name Strings of length 10 characters with all duplicates.

It can clearly be seen that the longer the strings the worse things get and that conversely the more duplicates the better things get. As previously mentioned duplicates don't affect the cached plan size so I presume that there must be a process of duplicate identification when constructing the algebrized expression tree itself.

Edit

One place where this information is leveraged is shown by @Lieven here

SELECT * 
FROM (VALUES ('Lieven1', 1),
             ('Lieven2', 2),
             ('Lieven3', 3))Test (name, ID)
ORDER BY name, 1/ (ID - ID) 

Because at compile time it can determine that the Name column has no duplicates it skips ordering by the secondary 1/ (ID - ID) expression at run time (the sort in the plan only has one ORDER BY column) and no divide by zero error is raised. If duplicates are added to the table then the sort operator shows two order by columns and the expected error is raised.

The internals of the GUI system call that method, and they pass in the Graphics parameter as a graphics context onto which you can draw.

I was running in to a problem with the standard way to do this:

$string = "one";

$float = (float)$string;

echo $float; : ( Prints 0 )

If there isn't a valid number, the parser shouldn't return a number, it should throw an error. (This is a condition I'm trying to catch in my code, YMMV)

To fix this I have done the following:

$string = "one";

$float = is_numeric($string) ? (float)$string : null;

echo $float; : ( Prints nothing )

Then before further processing the conversion, I can check and return an error if there wasn't a valid parse of the string.

0 for input, 1 for stdout and 2 for stderr.

One Tip: somecmd >1.txt 2>&1 is correct, while somecmd 2>&1 >1.txt is totally wrong with no effect!

=RIGHT(A1)  

is quite sufficient (where the string is contained in A1).

Similar in nature to LEFT, Excel's RIGHT function extracts a substring from a string starting from the right-most character:

SYNTAX

RIGHT( text, [number_of_characters] )

Parameters or Arguments

text

The string that you wish to extract from.

number_of_characters

Optional. It indicates the number of characters that you wish to extract starting from the right-most character. If this parameter is omitted, only 1 character is returned.

Applies To

Excel 2016, Excel 2013, Excel 2011 for Mac, Excel 2010, Excel 2007, Excel 2003, Excel XP, Excel 2000

Since number_of_characters is optional and defaults to 1 it is not required in this case.

However, there have been many issues with trailing spaces and if this is a risk for the last visible character (in general):

=RIGHT(TRIM(A1))  

might be preferred.

Here is a solution to prevent session shearing between browser tabs for a java application. This will work for IE (JSP/Servlet)

1. In your first JSP page, onload event call a servlet (ajex call) to setup a "window.title" and event tracker in the session(just a integer variable to be set as 0 for first time)
2. Make sure none of the other pages set a window.title
3. All pages (including the first page) add a java script to check the window title once the page load is complete. if the title is not found then close the current page/tab(make sure to undo the "window.unload" function when this occurs)
4. Set page window.onunload java script event(for all pages) to capture the page refresh event, if a page has been refreshed call the servlet to reset the event tracker.

1)first page JS

BODY onload="javascript:initPageLoad()"

function initPageLoad() {
    var xmlhttp;

    if (window.XMLHttpRequest) {
        // code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp = new XMLHttpRequest();
    } else {
        // code for IE6, IE5
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }

    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {                           var serverResponse = xmlhttp.responseText;
            top.document.title=serverResponse;
        }
    };
                xmlhttp.open("GET", 'data.do', true);
    xmlhttp.send();

}

2)common JS for all pages

window.onunload = function() {
    var xmlhttp;
    if (window.XMLHttpRequest) {
        // code for IE7+, Firefox, Chrome, Opera, Safari
        xmlhttp = new XMLHttpRequest();
    } else {
        // code for IE6, IE5
        xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
    }
    xmlhttp.onreadystatechange = function() {
        if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {             
            var serverResponse = xmlhttp.responseText;              
        }
    };

    xmlhttp.open("GET", 'data.do?reset=true', true);
    xmlhttp.send();
}

var readyStateCheckInterval = setInterval(function() {
if (document.readyState === "complete") {
    init();
    clearInterval(readyStateCheckInterval);
}}, 10);
function init(){ 
  if(document.title==""){   
  window.onunload=function() {};
  window.open('', '_self', ''); window.close();
  }
 }

3)web.xml - servlet mapping

<servlet-mapping>
<servlet-name>myAction</servlet-name>
<url-pattern>/data.do</url-pattern>     
</servlet-mapping>  
<servlet>
<servlet-name>myAction</servlet-name>
<servlet-class>xx.xxx.MyAction</servlet-class>
</servlet>

4)servlet code

public class MyAction extends HttpServlet {
 public void doGet(HttpServletRequest request, HttpServletResponse response)
        throws IOException {
    Integer sessionCount = (Integer) request.getSession().getAttribute(
            "sessionCount");
    PrintWriter out = response.getWriter();
    Boolean reset = Boolean.valueOf(request.getParameter("reset"));
    if (reset)
        sessionCount = new Integer(0);
    else {
        if (sessionCount == null || sessionCount == 0) {
            out.println("hello Title");
            sessionCount = new Integer(0);
        }
                          sessionCount++;
    }
    request.getSession().setAttribute("sessionCount", sessionCount);
    // Set standard HTTP/1.1 no-cache headers.
    response.setHeader("Cache-Control", "private, no-store, no-cache, must-                      revalidate");
    // Set standard HTTP/1.0 no-cache header.
    response.setHeader("Pragma", "no-cache");
} 
  }

It is well defined behaviour. You cannot get the old value for a mutated object. That's because both the newVal and oldVal refer to the same object. Vue will not keep an old copy of an object that you mutated.

Had you replaced the object with another one, Vue would have provided you with correct references.

Read the Note section in the docs. (vm.$watch)

For Me I just wanted to see the error in my VBA application so in the function I created the below code..

Function Database_FileRpt
'-------------------------

You're looking for itertools.compress:

>>> from itertools import compress
>>> list_a = [1, 2, 4, 6]

You can use LOAD DATA INFILE command to import csv file into table.

Check this link MySQL - LOAD DATA INFILE.

LOAD DATA LOCAL INFILE 'abc.csv' INTO TABLE abc
FIELDS TERMINATED BY ',' 
ENCLOSED BY '"' 
LINES TERMINATED BY '\r\n'
IGNORE 1 LINES
(col1, col2, col3, col4, col5...);

For MySQL 8.0 users:

Using the LOCAL keyword hold security risks and as of MySQL 8.0 the LOCAL capability is set to False by default. You might see the error:

ERROR 1148: The used command is not allowed with this MySQL version

You can overwrite it by following the instructions in the docs. Beware that such overwrite does not solve the security issue but rather just an acknowledge that you are aware and willing to take the risk.

I had a console application where I also had done a "Publish" to create an Install disk.
I was getting the same error at the OP:

The solution was right click setup.exe and click Run as Administrator

This enabled the install process the necessary privilege's.

private List<Url> AddURLToFile(Urls urls, Url url)
{
    string filePath = @"D:\test\file.json";
    urls.UrlList.Add(url);

    //if (!System.IO.File.Exists(filePath))
    //    using (System.IO.File.Delete(filePath));

    System.IO.File.WriteAllText(filePath, JsonConvert.SerializeObject(urls.UrlList));

    //using (StreamWriter sw = (System.IO.File.Exists(filePath)) ? System.IO.File.AppendText(filePath) : System.IO.File.CreateText(filePath))
    //{
    //    sw.WriteLine(JsonConvert.SerializeObject(urls.UrlList));
    //}
    return urls.UrlList;
}

private List<Url> ReadURLToFile()
{
    //  string filePath = Path.Combine(Path.GetDirectoryName(Assembly.GetExecutingAssembly().Location), @"App_Data\file.json");
    string filePath = @"D:\test\file.json";

    List<Url> result = new List<Url>(); ;
    if (!System.IO.File.Exists(filePath))
        using (System.IO.File.CreateText(filePath)) ;



    using (StreamReader file = new StreamReader(filePath))
    {
        result = JsonConvert.DeserializeObject<List<Url>>(file.ReadToEnd());
        file.Close();
    }
    if (result == null)
        result = new List<Url>();

    return result;

}

Make sure your computer is connected to the internet, then click on the link that comes with the error message i.e "install missing platform(s) and sync project". Give it a few seconds especially if your computer has low specs, it will bring up a window called SDK Quickfix Installation and everything is straightforward from there.

In addition to previous answers there is one important for me note:

shelve is JetBrains products feature (such as WebStorm, PhpStorm, PyCharm, etc.). It puts shelved files into .idea/shelf directory.

stash is one of git options. It puts stashed files under the .git directory.

That's constructor initialisation. It is the correct way to initialise members in a class constructor, as it prevents the default constructor being invoked.

Consider these two examples:

// Example 1
Foo(Bar b)
{
   bar = b;
}

// Example 2
Foo(Bar b)
   : bar(b)
{
}

In example 1:

Bar bar;  // default constructor
bar = b;  // assignment

In example 2:

Bar bar(b) // copy constructor

It's all about efficiency.

I have made a library SimpleHashing.Net to make the process of hashing easy with basic classes provided by Microsoft. Ordinary SHA is not really enough to have passwords stored securely anymore.

The library use the idea of hash format from Bcrypt, but since there is no official MS implementation I prefer to use what's available in the framework (i.e. PBKDF2), but it's a bit too hard out of the box.

This is a quick example how to use the library:

ISimpleHash simpleHash = new SimpleHash();

// Creating a user hash, hashedPassword can be stored in a database
// hashedPassword contains the number of iterations and salt inside it similar to bcrypt format
string hashedPassword = simpleHash.Compute("Password123");

// Validating user's password by first loading it from database by username
string storedHash = _repository.GetUserPasswordHash(username);
isPasswordValid = simpleHash.Verify("Password123", storedHash);

1. download the source code of php 7 and extract it.
2. open your terminal
3. swim to the ext/mysqli directory
4. use commands:

   phpize

   ./configure

   make

   make install (as root)

5. enable extension=mysqli.so in your php.ini file
6. done!

This worked for me

UTF-8 is a superset of ASCII. Either your UTF-8 file is ASCII, or it can't be converted without loss.

 X <- data.frame(Variable1=c(11,14,12,15),Variable2=c(2,3,1,4))
> X
  Variable1 Variable2
1        11         2
2        14         3
3        12         1
4        15         4
> X[X$Variable1!=11 & X$Variable1!=12, ]
  Variable1 Variable2
2        14         3
4        15         4
> X[ ! X$Variable1 %in% c(11,12), ]
  Variable1 Variable2

You can functionalize this however you like.

There's more to it than this, but you're probably looking for this list:

MSDN has a good explanation:

Assemblies are the building blocks of .NET Framework applications; they form the fundamental unit of deployment, version control, reuse, activation scoping, and security permissions. An assembly is a collection of types and resources that are built to work together and form a logical unit of functionality. An assembly provides the common language runtime with the information it needs to be aware of type implementations. To the runtime, a type does not exist outside the context of an assembly.

The first 30 seconds of this video shows how to use the global search feature of Phpmyadmin and it works. it will search every table for a string.

http://www.vodahost.com/vodatalk/phpmyadmin-setup/62422-search-database-phpmyadmin.html

If you are limited to ES6, the best option is Promise all. Promise.all(array) also returns an array of promises after successfully executing all the promises in array argument. Suppose, if you want to update many student records in the database, the following code demonstrates the concept of Promise.all in such case-

let promises = students.map((student, index) => {
//where students is a db object
student.rollNo = index + 1;
student.city = 'City Name';
//Update whatever information on student you want
return student.save();
});
Promise.all(promises).then(() => {
  //All the save queries will be executed when .then is executed
  //You can do further operations here after as all update operations are completed now
});

Map is just an example method for loop. You can also use for or forin or forEach loop. So the concept is pretty simple, start the loop in which you want to do bulk async operations. Push every such async operation statement in an array declared outside the scope of that loop. After the loop completes, execute the Promise all statement with the prepared array of such queries/promises as argument.

The basic concept is that the javascript loop is synchronous whereas database call is async and we use push method in loop that is also sync. So, the problem of asynchronous behavior doesn't occur inside the loop.

I ran into this as well, but in the case where I wanted to avoid the extra error messages while keeping the range provided. An option is also to subset the data prior to setting the range, so that the range can be kept however you like without triggering warnings.

library(ggplot2)

range(mtcars$hp)
#> [1]  52 335

# Setting limits with scale_y_continous (or ylim) and subsetting accordingly
## avoid warning messages about removing data
ggplot(data= subset(mtcars, hp<=300 & hp >= 100), aes(mpg, hp)) + 
  geom_point() +
  scale_y_continuous(limits=c(100,300))

U can use something like this....

  function (field,value) {

         var newItemOrder= value;
          // Make sure user hasnt already added this item
        angular.forEach(arr, function(item) {
            if (newItemOrder == item.value) {
                arr.splice(arr.pop(item));

            } });

        submitFields.push({"field":field,"value":value});
    };

I had the same problem and I had solved it with:

1.Right click to solution and click 'Clean Solution'

2.Click 'References' folder in solution explorer and select the problem reference (in your case it seems System.Web.Mvc) and then right click and click 'Properties'.

3.In the properties window, make sure that the 'Copy Local' property is set to 'True'

This worked for me. Hope it works for someone else

Helpful Note: As it has mentioned in comments by @Vlad:

If it is already set to True:

1. Set it False
2. Set it True again
3. Rebuild

I think the task scheduler would be overkill (imho). There is a startup folder for win7.

C:\Users\miliu\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup

Just create a shortcut for your autostart Applicaton, edit the properties of the shortcut and have it always run as administrator.

Your kids could close it of course, but if they are tech-savvy they always find a way to keep you out. I know i did when i was younger.

Good luck!

Use append method, eg:

lst = []
line = np.genfromtxt('temp.txt', usecols=3, dtype=[('floatname','float')], skip_header=1)
lst.append(line)

Basic syntax is: $(selector).action()

A dollar sign to define jQuery A (selector) to "query (or find)" HTML elements A jQuery action() to be performed on the element(s)

I had the same issue of Action-bar Home button icon direction,because of miss managing of Icon in Gradle Resource directory icon

like in Arabic Gradle resource directory you put icon in x-hdpi and in English Gradle resource same icon name you put in different density folder like xx-hdpi ,so that in APK there will be two same icon names in different directories,so your device will pick density dependent icon may be RTL or LTR

When you need to toggle an element away, and you don't need to animate the margin property. You could try margin-top: -999999em. Just don't transition all.

Insertion Sort

After i iterations the first i elements are ordered.

In each iteration the next element is bubbled through the sorted section until it reaches the right spot:

sorted  | unsorted
1 3 5 8 | 4 6 7 9 2
1 3 4 5 8 | 6 7 9 2

The 4 is bubbled into the sorted section

Pseudocode:

for i in 1 to n
    for j in i downto 2
        if array[j - 1] > array[j]
            swap(array[j - 1], array[j])
        else
            break

Bubble Sort

After i iterations the last i elements are the biggest, and ordered.

In each iteration, sift through the unsorted section to find the maximum.

unsorted  | biggest
3 1 5 4 2 | 6 7 8 9
1 3 4 2 | 5 6 7 8 9

The 5 is bubbled out of the unsorted section

Pseudocode:

for i in 1 to n
    for j in 1 to n - i
         if array[j] > array[j + 1]
             swap(array[j], array[j + 1])

Note that typical implementations terminate early if no swaps are made during one of the iterations of the outer loop (since that means the array is sorted).

Difference

In insertion sort elements are bubbled into the sorted section, while in bubble sort the maximums are bubbled out of the unsorted section.

As you say, ordinal is a bit risky. Consider for example:

public enum Boolean {
    TRUE, FALSE
}

public class BooleanTest {
    @Test
    public void testEnum() {
        assertEquals(0, Boolean.TRUE.ordinal());
        assertEquals(1, Boolean.FALSE.ordinal());
    }
}

If you stored this as ordinals, you might have rows like:

> SELECT STATEMENT, TRUTH FROM CALL_MY_BLUFF

"Alice is a boy"      1
"Graham is a boy"     0

But what happens if you updated Boolean?

public enum Boolean {
    TRUE, FILE_NOT_FOUND, FALSE
}

This means all your lies will become misinterpreted as 'file-not-found'

Better to just use a string representation

Step 1:Create a XML File

            student.setAddress("Banglore");
            studentArrayList.add(student);
        }

            tvStudPhone.setText(student.getPhone());
            tvStudAddress.setText(student.getAddress());


            return convertView;
        }
    }

I do this to post a delayed runnable:

myHandler.postDelayed(myRunnable, SPLASH_DISPLAY_LENGTH); 

And this to remove it: myHandler.removeCallbacks(myRunnable);

You don't. strings.xml is just here to define the raw text messages. You should (must) use styles.xml to define reusable visual styles to apply to your widgets.

Think of it as a good practice to separate the concerns. You can work on the visual styles independently from the text messages.

When I encountered a similar problem, I fixed it by substituting &mode=xml for &mode=json in the request.

Another, more Windows-y option (for $39) is http://www.expandrive.com/sftpdrive

I arrived at this peculiar, hard-to-debug error through a different route. My trouble ended up being that I was using a pattern rule in a build step when the target and the dependency were located in distinct directories. Something like this:

foo/apple.o: bar/apple.c $(FOODEPS)

%.o: %.c
    $(CC) $< -o $@

I had several dependencies set up this way, and was trying to use one pattern recipe for them all. Clearly, a single substitution for "%" isn't going to work here. I made explicit rules for each dependency, and I found myself back among the puppies and unicorns!

foo/apple.o: bar/apple.c $(FOODEPS)
    $(CC) $< -o $@

Hope this helps someone!

Your class doesn't have a __init__(), so by the time it's instantiated, the attribute atoms is not present. You'd have to do C.setdata('something') so C.atoms becomes available.

>>> C = Residues()
>>> C.atoms.append('thing')

Traceback (most recent call last):
  File "<pyshell#84>", line 1, in <module>
    B.atoms.append('thing')
AttributeError: Residues instance has no attribute 'atoms'

>>> C.setdata('something')
>>> C.atoms.append('thing')   # now it works
>>> 

Unlike in languages like Java, where you know at compile time what attributes/member variables an object will have, in Python you can dynamically add attributes at runtime. This also implies instances of the same class can have different attributes.

To ensure you'll always have (unless you mess with it down the line, then it's your own fault) an atoms list you could add a constructor:

def __init__(self):
    self.atoms = []

SQL Developer 4.1, released in May of 2015, added a Model tab which shows table foreign keys which refer to your table in an Entity Relationship Diagram format.

You can use .sortBy, it will always return an ascending list:

_.sortBy([2, 3, 1], function(num) {
    return num;
}); // [1, 2, 3]

But you can use the .reverse method to get it descending:

var array = _.sortBy([2, 3, 1], function(num) {
    return num;
});

console.log(array); // [1, 2, 3]
console.log(array.reverse()); // [3, 2, 1]

Or when dealing with numbers add a negative sign to the return to descend the list:

_.sortBy([-3, -2, 2, 3, 1, 0, -1], function(num) {
    return -num;
}); // [3, 2, 1, 0, -1, -2, -3]

Under the hood .sortBy uses the built in .sort([handler]):

// Default is ascending:
[2, 3, 1].sort(); // [1, 2, 3]

// But can be descending if you provide a sort handler:
[2, 3, 1].sort(function(a, b) {
    // a = current item in array
    // b = next item in array
    return b - a;
});

Nothing wrong with the other answers but this one offers a non-programmatic solution that may be useful in situations where one has a small static table. The benefit is that one can organize the localizations using the storyboard. One may continue to export localizations from Xcode via XLIFF files. Xcode 9 also has several new tools to make localizations easier.

(original)

I had a similar requirement. I had a static table with static cells in my Main.storyboard(Base). To localize section titles using .string files e.g. Main.strings(German) just select the section in storyboard and note the Object ID

Afterwards go to your string file, in my case Main.strings(German) and insert the translation like:

"MLo-jM-tSN.headerTitle" = "Localized section title";

PowerShell 3 has the $PSScriptRoot automatic variable:

Contains the directory from which a script is being run.

In Windows PowerShell 2.0, this variable is valid only in script modules (.psm1). Beginning in Windows PowerShell 3.0, it is valid in all scripts.

Don't be fooled by the poor wording. PSScriptRoot is the directory of the current file.

In PowerShell 2, you can calculate the value of $PSScriptRoot yourself:

# PowerShell v2
$PSScriptRoot = Split-Path -Parent -Path $MyInvocation.MyCommand.Definition

SELECT tab.*,
    row_number() OVER () as rnum
  FROM tab;

Here's the relevant section in the docs.

P.S. This, in fact, fully matches the answer in the referenced question.

Somthing like this should workL

SELECT BookingId, StartTime
FROM Booking
WHERE StartTime between dateadd(hour, -1, getdate()) and getdate()

Using Linux Top command

top -H -p (process id)

you could get process id of one program by this method :

ps aux | grep (your program name)

for example :

ps aux | grep user.py

As Karthik mentioned, dct.keys() will work but it will return all the keys in dict_keys type not in list type. So if you want all the keys in a list, then list(dct.keys()) will work.

#The Best way is to use `fStrings` (very easy and powerful in python3)   
#Format: f'your-string'   
#For Example:

mylist=['laks',444,'M']

cursor.execute(f'INSERT INTO mytable VALUES ("{mylist[0]}","{mylist[1]}","{mylist[2]}")')

#THATS ALL!! EASY!!
#You can use it with for loop!

Instead of using the % unit – the width/height of another element – you should use vh and vw.
Your code would be:

your table {
  width: 100vw;
  height: 100vh;
}

But, if the document is smaller than 100vh or 100vw, then you need to set the size to the document's size.

(table).style.width = window.innerWidth;
(table).style.height = window.innerHeight;

Even when i was learning node.js for the first time where i started learning it over web-app, i was having all these things done in well manner in my form, still i was not able to receive values in post request. After long debugging, i came to know that in the form i have provided enctype="multipart/form-data" due to which i was not able to get values. I simply removed it and it worked for me.

The "call" solution has some problems.

It fails with many different contents, as the parameters of a CALL are parsed twice by the parser.
These lines will produce more or less strange problems

one
two%222
three & 333
four=444
five"555"555"
six"&666
seven!777^!
the next line is empty

the end

Therefore you shouldn't use the value of %%a with a call, better move it to a variable and then call a function with only the name of the variable.

@echo off
SETLOCAL DisableDelayedExpansion
FOR /F "usebackq delims=" %%a in (`"findstr /n ^^ t.txt"`) do (
    set "myVar=%%a"
    call :processLine myVar
)
goto :eof

:processLine
SETLOCAL EnableDelayedExpansion
set "line=!%1!"
set "line=!line:*:=!"
echo(!line!
ENDLOCAL
goto :eof

you can do something like this:

foreach (var file in Directory.GetFiles(MyFolder, "*.xml", SearchOption.AllDirectories))
        {
            // do something with this file
        }

you can set this in catalina.sh as CATALINA_OPTS=-Xms512m -Xmx512m

Open your tomcat-dir/bin/catalina.sh file and add following line anywhere -

CATALINA_OPTS="$CATALINA_OPTS -Xms1024m -Xmx3024m"

and restart your tomcat

On 4.0.6, below is the solution that worked for me. Had to include select2-selection__rendered and select2-selection__arrow to vertically align the dropdown label and the arrow icon:

.select2-container .select2-selection, 
.select2-selection__rendered, 
.select2-selection__arrow {
    height: 48px !important;
    line-height: 48px !important;
}

This configuration to your nginx.conf should help you.

https://gist.github.com/baskaran-md/e46cc25ccfac83f153bb

server {
    listen       80;
    server_name  localhost;

    location / {
        root   html;
        index  index.html index.htm;
    }

    error_page  404     /404.html;
    error_page  403     /403.html;

    # To allow POST on static pages
    error_page  405     =200 $uri;

    # ...
}

The answers above will work for changing the values.

If you want to change the number of cells in your list (e.g. I have a list called 'revisions' which has 4 items, I now need 7 items) you will find that you can't simply select your list and amend it on the sheet, So:

go to your 'Formulas' tab

choose "Name Manager"

a pop up box will show what is available for editing. Your list should be in it. Select your list and edit the range.

Try this

isPalindrome = (string) => {
    if (string === string.split('').reverse().join('')) {
        console.log('is palindrome');
    }
    else {
        console.log('is not palindrome');
    }
}

isPalindrome(string)

The answer of Uttam didnt work for me. I just got null when I do:

Bitmap bitmap = BitmapFactory.decodeByteArray(bitmapdata, 0, bitmapdata.length);

In my case, bitmapdata only has the buffer of the pixels, so it is imposible for the function decodeByteArray to guess which the width, the height and the color bits use. So I tried this and it worked:

//Create bitmap with width, height, and 4 bytes color (RGBA)    
Bitmap bmp = Bitmap.createBitmap(imageWidth, imageHeight, Bitmap.Config.ARGB_8888);
ByteBuffer buffer = ByteBuffer.wrap(bitmapdata);
bmp.copyPixelsFromBuffer(buffer);

Check https://developer.android.com/reference/android/graphics/Bitmap.Config.html for different color options

Sometimes we have an upstream that rebased/rewound a branch we're depending on. This can be a big problem -- causing messy conflicts for us if we're downstream.

The magic is git pull --rebase

A normal git pull is, loosely speaking, something like this (we'll use a remote called origin and a branch called foo in all these examples):

# assume current checked out branch is "foo"
git fetch origin
git merge origin/foo

At first glance, you might think that a git pull --rebase does just this:

git fetch origin
git rebase origin/foo

But that will not help if the upstream rebase involved any "squashing" (meaning that the patch-ids of the commits changed, not just their order).

Which means git pull --rebase has to do a little bit more than that. Here's an explanation of what it does and how.

Let's say your starting point is this:

a---b---c---d---e  (origin/foo) (also your local "foo")

Time passes, and you have made some commits on top of your own "foo":

a---b---c---d---e---p---q---r (foo)

Meanwhile, in a fit of anti-social rage, the upstream maintainer has not only rebased his "foo", he even used a squash or two. His commit chain now looks like this:

a---b+c---d+e---f  (origin/foo)

A git pull at this point would result in chaos. Even a git fetch; git rebase origin/foo would not cut it, because commits "b" and "c" on one side, and commit "b+c" on the other, would conflict. (And similarly with d, e, and d+e).

What git pull --rebase does, in this case, is:

git fetch origin
git rebase --onto origin/foo e foo

This gives you:

 a---b+c---d+e---f---p'---q'---r' (foo)

You may still get conflicts, but they will be genuine conflicts (between p/q/r and a/b+c/d+e/f), and not conflicts caused by b/c conflicting with b+c, etc.

Answer taken from (and slightly modified):
http://gitolite.com/git-pull--rebase

A simpler way is

ggplot(data=df, aes(x=xvar, y=yvar)) + 
geom_point()

ggsave(path = path, width = width, height = height, device='tiff', dpi=700)

It's an encoding error - so if it's a unicode string, this ought to fix it:

text.encode("windows-1252").decode("utf-8")

If it's a plain string, you'll need an extra step:

text.decode("utf-8").encode("windows-1252").decode("utf-8")

Both of these will give you a unicode string.

By the way - to discover how a piece of text like this has been mangled due to encoding issues, you can use chardet:

>>> import chardet
>>> chardet.detect(u"And the Hip’s coming, too")
{'confidence': 0.5, 'encoding': 'windows-1252'}

Follow the steps below:

1- git stash
2- git add .
3- git commit -m "your commit message"

Many commenters in this question don't understand how arrays work in PHP. From the array documentation:

A key may be either an integer or a string. If a key is the standard representation of an integer, it will be interpreted as such (i.e. "8" will be interpreted as 8, while "08" will be interpreted as "08"). Floats in key are truncated to integer. The indexed and associative array types are the same type in PHP, which can both contain integer and string indices.

In other words, there is no such thing as an array key of "8" because it will always be (silently) converted to the integer 8. So trying to differentiate between integers and numeric strings is unnecessary.

If you want the most efficient way to check an array for non-integer keys without making a copy of part of the array (like array_keys() does) or all of it (like foreach does):

function keyedNext( &$arr, &$k){
    $k = key($arr);
    return next($arr);
}

for ($k = key(reset($my_array)); is_int($k); keyedNext($my_array,$k))
    $onlyIntKeys = is_null($k);

This works because key() returns NULL when the current array position is invalid and NULL can never be a valid key (if you try to use NULL as an array key it gets silently converted to "").

Create a custom adapter with a custom layout for your spinner.

Spinner spinner = (Spinner) findViewById(R.id.pioedittxt5);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this,
        R.array.travelreasons, R.layout.simple_spinner_item);
adapter.setDropDownViewResource(R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);

R.layout.simple_spinner_item

<TextView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@android:id/text1"
    style="@style/spinnerItemStyle"
    android:maxLines="1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:ellipsize="marquee" />

R.layout.simple_spinner_dropdown_item

<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@android:id/text1"
    style="@style/spinnerDropDownItemStyle"
    android:maxLines="1"
    android:layout_width="match_parent"
    android:layout_height="?android:attr/dropdownListPreferredItemHeight"
    android:ellipsize="marquee" />

In styles add your custom dimensions and height as per your requirement.

 <style name="spinnerItemStyle" parent="android:Widget.TextView.SpinnerItem">

  </style>

  <style name="spinnerDropDownItemStyle" parent="android:TextAppearance.Widget.TextView.SpinnerItem">

  </style>

If you are looking specifically for memory in JVM:

Runtime runtime = Runtime.getRuntime();

NumberFormat format = NumberFormat.getInstance();

StringBuilder sb = new StringBuilder();
long maxMemory = runtime.maxMemory();
long allocatedMemory = runtime.totalMemory();
long freeMemory = runtime.freeMemory();

sb.append("free memory: " + format.format(freeMemory / 1024) + "<br/>");
sb.append("allocated memory: " + format.format(allocatedMemory / 1024) + "<br/>");
sb.append("max memory: " + format.format(maxMemory / 1024) + "<br/>");
sb.append("total free memory: " + format.format((freeMemory + (maxMemory - allocatedMemory)) / 1024) + "<br/>");

However, these should be taken only as an estimate...

This problem:

$ brew install docker docker-machine
$ docker ps

Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

This apparently meant do the following:

$ docker-machine create default # default driver is apparently vbox:
Running pre-create checks...
Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"
$  brew cask install virtualbox
…
$ docker-machine create default 
# works this time
$ docker ps
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
$ eval "$(docker-machine env default)"
$ docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES

It finally works.

You can use the “xhyve” driver if you don’t want to install virtual box. Also you can install the “docker app” (then run it) which apparently makes it so you don’t have to run some of the above. brew cask install docker then run the app, see the other answers. But apparently isn't necessary per se.

I have found that if the view model contains many div bindings the best way to clear the ko.applyBindings(new someModelView); is to use: ko.cleanNode($("body")[0]); This allows you to call a new ko.applyBindings(new someModelView2); dynamically without the worry of the previous view model still being binded.

In xml there is option

android:spinnerMode="dialog"

use this for Dialog mode

Here's what we came up with for copying one field to another for ~150_000 records. It took about 6 minutes, but is still significantly less resource intensive than it would have been to instantiate and iterate over the same number of ruby objects.

js_query = %({
  $or : [
    {
      'settings.mobile_notifications' : { $exists : false },
      'settings.mobile_admin_notifications' : { $exists : false }
    }
  ]
})

js_for_each = %(function(user) {
  if (!user.settings.hasOwnProperty('mobile_notifications')) {
    user.settings.mobile_notifications = user.settings.email_notifications;
  }
  if (!user.settings.hasOwnProperty('mobile_admin_notifications')) {
    user.settings.mobile_admin_notifications = user.settings.email_admin_notifications;
  }
  db.users.save(user);
})

js = "db.users.find(#{js_query}).forEach(#{js_for_each});"
Mongoid::Sessions.default.command('$eval' => js)

Honestly alot of the answers are old so i found that if you simply just test any string regardless of character content with "/.*/i" will sufficiently get EVERYTHING.

You are actually trying to redirect a page which has some response to throw. So first you keep the information you have throw in a buffer using response.buffer = true in beginning of the page and then flush it when required using response.flush this error will get fixed

I am just student working on my master's thesis, but this is the way I solved it and it worked well for me. First you select your file from directory (only in csv format) and then you put the data into the lists.

List<float> t = new List<float>();
List<float> SensorI = new List<float>();
List<float> SensorII = new List<float>();
List<float> SensorIII = new List<float>();
using (OpenFileDialog dialog = new OpenFileDialog())
{
    try
    {
        dialog.Filter = "csv files (*.csv)|*.csv";
        dialog.Multiselect = false;
        dialog.InitialDirectory = ".";
        dialog.Title = "Select file (only in csv format)";
        if (dialog.ShowDialog() == DialogResult.OK)
        {
            var fs = File.ReadAllLines(dialog.FileName).Select(a => a.Split(';'));
            int counter = 0;
            foreach (var line in fs)
            {
                counter++;
                if (counter > 2)    // Skip first two headder lines
                {
                    this.t.Add(float.Parse(line[0]));
                    this.SensorI.Add(float.Parse(line[1]));
                    this.SensorII.Add(float.Parse(line[2]));
                    this.SensorIII.Add(float.Parse(line[3]));
                }
            }
        }
    }
    catch (Exception exc)
    {
        MessageBox.Show(
            "Error while opening the file.\n" + exc.Message, 
            this.Text, 
            MessageBoxButtons.OK, 
            MessageBoxIcon.Error
        );
    }
}

Just pass it in, like this:

Game(list_a, list_b, Rule1)

and then your Game function could look something like this (still pseudocode):

def Game(listA, listB, rules=None):
    if rules:
        # do something useful
        # ...
        result = rules(variable) # this is how you can call your rule
    else:
        # do something useful without rules

In a similar case, I wanted to avoid always calling addClass or removeClass due to performance issues. I've split the scroll handler function into two individual functions, used according to the current state. I also added a debounce functionality according to this article: https://developers.google.com/web/fundamentals/performance/rendering/debounce-your-input-handlers

        var $header = jQuery( ".clearHeader" );         
        var appScroll = appScrollForward;
        var appScrollPosition = 0;
        var scheduledAnimationFrame = false;

        function appScrollReverse() {
            scheduledAnimationFrame = false;
            if ( appScrollPosition > 500 )
                return;
            $header.removeClass( "darkHeader" );
            appScroll = appScrollForward;
        }

        function appScrollForward() {
            scheduledAnimationFrame = false;
            if ( appScrollPosition < 500 )
                return;
            $header.addClass( "darkHeader" );
            appScroll = appScrollReverse;
        }

        function appScrollHandler() {
            appScrollPosition = window.pageYOffset;
            if ( scheduledAnimationFrame )
                return;
            scheduledAnimationFrame = true;
            requestAnimationFrame( appScroll );
        }

        jQuery( window ).scroll( appScrollHandler );

Maybe someone finds this helpful.

Sometimes when we do these steps:

 alter table my_table drop constraint my_pk; 
 alter table my_table add constraint my_pk primary key (city_id, buildtime, time);

The last statement fails with

ORA-00955 "name is already used by an existing object"

Oracle usually creates an unique index with the same name my_pk. In such a case you can drop the unique index or rename it based on whether the constraint is still relevant.

You can combine the dropping of primary key constraint and unique index into a single sql statement:

alter table my_table drop constraint my_pk drop index; 

check this: ORA-00955 "name is already used by an existing object"

I created a comparison of all the solutions mentioned here to have a quick overview:

I've installed java and tomcat in D drive henceforth the locations above are under my respective paths.

Give location paths where java and tomcat are installed in your PC. Thank You

I find it very interesting that no one considered using UTC since it is not subject to DST. Therefore, I propose the following:

function daysIntoYear(date){
    return (Date.UTC(date.getFullYear(), date.getMonth(), date.getDate()) - Date.UTC(date.getFullYear(), 0, 0)) / 24 / 60 / 60 / 1000;
}

You can test it with the following:

[new Date(2016,0,1), new Date(2016,1,1), new Date(2016,2,1), new Date(2016,5,1), new Date(2016,11,31)]
    .forEach(d => 
        console.log(`${d.toLocaleDateString()} is ${daysIntoYear(d)} days into the year`));

Which outputs for the leap year 2016 (verified using http://www.epochconverter.com/days/2016):

1/1/2016 is 1 days into the year
2/1/2016 is 32 days into the year
3/1/2016 is 61 days into the year
6/1/2016 is 153 days into the year
12/31/2016 is 366 days into the year

Inside of VBS you can access parameters with

Wscript.Arguments(0)
Wscript.Arguments(1)

and so on. The number of parameter:

Wscript.Arguments.Count

Also make sure your Workspace Settings aren't overriding your User Settings. The UI doesn't make it very obvious which settings you're editing and "File > Preferences > Settings" defaults to User Settings even though Workspace Settings trump User Settings.

You can also edit Workspace settings directly: /.vscode/settings.json

If you dont want your local changes, then do below command to ignore(delete permanently) the local changes.

• If its unstaged changes, then do checkout (git checkout <filename> or git checkout -- .)
• If its staged changes, then first do reset (git reset <filename> or git reset) and then do checkout (git checkout <filename> or git checkout -- .)
• If it is untracted files/folders (newly created), then do clean (git clean -fd)

If you dont want to loose your local changes, then stash it and do pull or rebase. Later merge your changes from stash.

• Do git stash, and then get latest changes from repo git pull orign master or git rebase origin/master, and then merge your changes from stash git stash pop stash@{0}

They really should add a wrapper. Like this:

namespace std
{
    template<class _container,
        class _Ty> inline
        bool contains(_container _C, const _Ty& _Val)
        {return std::find(_C.begin(), _C.end(), _Val) != _C.end(); }
};
...
    if( std::contains(my_container, what_to_find) )
    {

    }

if you want to add the data in the increment order inside your associative array you can do this:

$newdata =  array (
      'wpseo_title' => 'test',
      'wpseo_desc' => 'test',
      'wpseo_metakey' => 'test'
    );

// for recipe

$md_array["recipe_type"][] = $newdata;

//for cuisine

 $md_array["cuisine"][] = $newdata;

this will get added to the recipe or cuisine depending on what was the last index.

Array push is usually used in the array when you have sequential index: $arr[0] , $ar[1].. you cannot use it in associative array directly. But since your sub array is had this kind of index you can still use it like this

array_push($md_array["cuisine"],$newdata);

Love it, lots of marks up but no answer :D

Simply put a comparison against zero is always the fastest comparison

So (a==0) is actually quicker at returning True than (a==5)

It's small and insignificant and with 100 million rows in a collection it's measurable.

i.e on a loop up you might be saying where i <= array.length and be incrementing i

on a down loop you might be saying where i >= 0 and be decrementing i instead.

The comparison is quicker. Not the 'direction' of the loop.

It's Very Simple First You Define a value

state = {
  checked_Array: []
}

Now,

fun(index) {
  var checked = this.state.checked_Array;
  var values = checked.indexOf(index)
  checked.splice(values, 1);
  this.setState({checked_Array: checked});
  console.log(this.state.checked_Array)
}

If you want to hide the cursor in the entire webpage, using body will not work unless it covers the entire visible page, which is not always the case. To make sure the cursor is hidden everywhere in the page, use:

document.documentElement.style.cursor = 'none';

To reenable it:

document.documentElement.style.cursor = 'auto';

The analogue with static CSS notation is in the answer by Pavel Salaquarda (in essence: html * {cursor:none})

Maybe loadash needs to be installed. Usually these things are handled by the package manager. On your command line:

npm install lodash 

or maybe it needs to be globally installed

npm install -g lodash

Just ran into this again (certain I had before and came up with a less-than-satisfying solution).

For a tri-state boolean semantic (for example, using models.NullBooleanField), this works well:

{% if test.passed|lower == 'false' %} ... {% endif %}

Or if you prefer getting excited over the whole thing...

{% if test.passed|upper == 'FALSE' %} ... {% endif %}

Either way, this handles the special condition where you don't care about the None (evaluating to False in the if block) or True case.

Just adding a fringe case - "Folder Selection." in path

In my app I get recently opened paths passed to me, some of which have "Folder Selection." at the end.

Some FileOpenDialogs and WinMerge add "Folder Selection." to paths (it's true).

But under Windows OS "Folder Selection." is not an advised file or folder name (as in don't do it, ever - shakes fist). As said here: http://msdn.microsoft.com/en-us/library/aa365247%28VS.85%29.aspx

Do not end a file or directory name with a space or a period. Although the underlying file system may support such names, the Windows shell and user interface does not. However, it is acceptable to specify a period as the first character of a name. For example, ".temp".

So whilst "Folder Selection." shouldn't be used, it can be. (awesome).

Enough explanation - my code (I like enums a lot):

public static class Utility
{
    public enum ePathType
    {
        ePathType_Unknown = 0,
        ePathType_ExistingFile = 1,
        ePathType_ExistingFolder = 2,
        ePathType_ExistingFolder_FolderSelectionAdded = 3,
    }

    public static ePathType GetPathType(string path)
    {
        if (File.Exists(path) == true) { return ePathType.ePathType_ExistingFile; }
        if (Directory.Exists(path) == true) { return ePathType.ePathType_ExistingFolder; }

        if (path.EndsWith("Folder Selection.") == true)
        {
            // Test the path again without "Folder Selection."
            path = path.Replace("\\Folder Selection.", "");
            if (Directory.Exists(path) == true)
            {
                // Could return ePathType_ExistingFolder, but prefer to let the caller known their path has text to remove...
                return ePathType.ePathType_ExistingFolder_FolderSelectionAdded;
            }
        }

        return ePathType.ePathType_Unknown;
    }
}

I am posting this as an answer not because it's the correct answer to your question, but because it's a solution to the same problem, but using attributes instead. Otherwise Vikas Gujjar's answer is correct.

Quite oftern your data could be in attributes, but it's quite hard to find any working examples using XStream to do this, so here's one:

Sample data:

<settings>
    <property name="prop1" value="foo"/>
    <property name="prop2" /> <!-- NOTE:
                                   The example supports null elements as
                                   the backing object is a HashMap.
                                   A Properties object would be handled
                                   by a PropertiesConverter which wouldn't
                                   allow you null values.  -->
    <property name="prop3" value="1"/>
</settings>

Implementation of MapEntryConverter (slightly re-worked @Vikas Gujjar's implementation to use attributes instead):

public class MapEntryConverter
        implements Converter
{

    public boolean canConvert(Class clazz)
    {
        return AbstractMap.class.isAssignableFrom(clazz);
    }

    public void marshal(Object value,
                        HierarchicalStreamWriter writer,
                        MarshallingContext context)
    {
        //noinspection unchecked
        AbstractMap<String, String> map = (AbstractMap<String, String>) value;
        for (Map.Entry<String, String> entry : map.entrySet())
        {
            //noinspection RedundantStringToString
            writer.startNode(entry.getKey().toString());
            //noinspection RedundantStringToString
            writer.setValue(entry.getValue().toString());
            writer.endNode();
        }
    }

    public Object unmarshal(HierarchicalStreamReader reader,
                            UnmarshallingContext context)
    {
        Map<String, String> map = new HashMap<String, String>();

        while (reader.hasMoreChildren())
        {
            reader.moveDown();
            map.put(reader.getAttribute("name"), reader.getAttribute("value"));
            reader.moveUp();
        }

        return map;
    }
}

XStream instance setup, parsing and storing:

    XStream xstream = new XStream();
    xstream.autodetectAnnotations(true);
    xstream.alias("settings", HashMap.class);
    xstream.registerConverter(new MapEntryConverter());
    ...
    // Parse:
    YourObject yourObject = (YourObject) xstream.fromXML(is);
    // Store:
    xstream.toXML(yourObject);
    ...

It took me a while to locate why the sample application works but mine don't.

The library (Foundation.Framework) that the author refer to is the system library (from OS) where the iphone sdk (I am using 3.0) is not support any more.

Therefore the sample application (from about.com, http://www.appsamuck.com/day1.html) works but ours don't.

Change the segue identifier in the right panel in the section with an id. icon to match the string you used in your conditional.

Please try this one:

function used_to_compare_two_arrays(a, b)
{
  // This block will make the array of indexed that array b contains a elements
  var c = a.filter(function(value, index, obj) {
    return b.indexOf(value) > -1;
  });

  // This is used for making comparison that both have same length if no condition go wrong 
  if (c.length !== a.length) {
    return 0;
  } else{
    return 1;
  }
}

In order to call this you will have to store a reference to your form and pass the reference to the run method. Then you can call this in an actionhandler.

public partial class Form1 : Form
{
    public void ChangeSize(int width, int height)
    {
        this.Size = new Size(width, height);
    }
}

Using npm

Latest version while still respecting the semver in your package.json: npm update <package-name>. So, if your package.json says "react": "^15.0.0" and you run npm update react your package.json will now say "react": "^15.6.2" (the currently latest version of react 15).

But since you want to go from react 15 to react 16, that won't do. Latest version regardless of your semver: npm install --save react@latest.

If you want a specific version, you run npm install --save react@<version> e.g. npm install --save [email protected].

https://docs.npmjs.com/cli/install

Using yarn

Latest version while still respecting the semver in your package.json: yarn upgrade react.

Latest version regardless of your semver: yarn upgrade react@latest.

https://yarnpkg.com/lang/en/docs/cli/upgrade/

Yes.

You can create anonymous methods or lambda expressions:

Func<string, string> PrefixTrimmer = delegate(string x) {
    return x ?? "";
};
Func<string, string> PrefixTrimmer = x => x ?? "";

To add a little bit more information that confused me; I had always thought the same result could be achieved like so;

theDate.ToString("yyyy-MM-dd HH:mm:ss")

However, If your Current Culture doesn't use a colon(:) as the hour separator, and instead uses a full-stop(.) it could return as follow:

2009-06-15 13.45.30

Just wanted to add why the answer provided needs to be as it is;

theDate.ToString("yyyy-MM-dd HH':'mm':'ss")

:-)

JQuery is looking for a json type result, but because the redirect is processed automatically, it will receive the generated html source of your login.htm page.

One idea is to let the the browser know that it should redirect by adding a redirect variable to to the resulting object and checking for it in JQuery:

$(document).ready(function(){ 
    jQuery.ajax({ 
        type: "GET", 
        url: "populateData.htm", 
        dataType:"json", 
        data:"userId=SampleUser", 
        success:function(response){ 
            if (response.redirect) {
                window.location.href = response.redirect;
            }
            else {
                // Process the expected results...
            }
        }, 
     error: function(xhr, textStatus, errorThrown) { 
            alert('Error!  Status = ' + xhr.status); 
         } 

    }); 
}); 

You could also add a Header Variable to your response and let your browser decide where to redirect. In Java, instead of redirecting, do response.setHeader("REQUIRES_AUTH", "1") and in JQuery you do on success(!):

//....
        success:function(response){ 
            if (response.getResponseHeader('REQUIRES_AUTH') === '1'){ 
                window.location.href = 'login.htm'; 
            }
            else {
                // Process the expected results...
            }
        }
//....

Hope that helps.

My answer is heavily inspired by this thread which shouldn't left any questions in case you still have some problems.

String to byte array: "FooBar".split('').map(c => c.charCodeAt(0));

Byte array to string: [102, 111, 111, 98, 97, 114].map(c => String.fromCharCode(c)).join('');

document.getElementById("address_box").value = 
(title + "\n" + address + "\n" + address2 + "\n" + address3 + "\n" + address4);

You would need to do something like this. I am typing this off the top of my head, so this may not be 100% correct.

CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, 640, 360, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(colorSpace);  CGContextDrawImage(context, CGRectMake(0,-160,640,360), cgImgFromAVCaptureSession);  CGImageRef image = CGBitmapContextCreateImage(context); UIImage* myCroppedImg = [UIImage imageWithCGImage:image]; CGContextRelease(context);       

Instanceof works if you don't depend on specific classes, but also keep in mind that you can have nulls in the list, so obj.getClass() will fail, but instanceof always returns false on null.

Adding to jelovirt's answer, you can use number() to convert the value to a number, then round(), floor(), or ceiling() to get a whole integer.

Example

<xsl:variable name="MyValAsText" select="'5.14'"/>
<xsl:value-of select="number($MyValAsText) * 2"/> <!-- This outputs 10.28 -->
<xsl:value-of select="floor($MyValAsText)"/> <!-- outputs 5 -->
<xsl:value-of select="ceiling($MyValAsText)"/> <!-- outputs 6 -->
<xsl:value-of select="round($MyValAsText)"/> <!-- outputs 5 -->

First of all, android.graphics.Color is a class thats composed of only static methods. How and why did you create a new android.graphics.Color object? (This is completely useless and the object itself stores no data)

But anyways... I'm going to assume your using some object that actually stores data...

A integer is composed of 4 bytes (in java). Looking at the function getRGB() from the standard java Color object we can see java maps each color to one byte of the integer in the order ARGB (Alpha-Red-Green-Blue). We can replicate this behavior with a custom method as follows:

public int getIntFromColor(int Red, int Green, int Blue){
    Red = (Red << 16) & 0x00FF0000; //Shift red 16-bits and mask out other stuff
    Green = (Green << 8) & 0x0000FF00; //Shift Green 8-bits and mask out other stuff
    Blue = Blue & 0x000000FF; //Mask out anything not blue.

    return 0xFF000000 | Red | Green | Blue; //0xFF000000 for 100% Alpha. Bitwise OR everything together.
}

This assumes you can somehow retrieve the individual red, green and blue colour components and that all the values you passed in for the colours are 0-255.

If your RGB values are in form of a float percentage between 0 and 1 consider the following method:

public int getIntFromColor(float Red, float Green, float Blue){
    int R = Math.round(255 * Red);
    int G = Math.round(255 * Green);
    int B = Math.round(255 * Blue);

    R = (R << 16) & 0x00FF0000;
    G = (G << 8) & 0x0000FF00;
    B = B & 0x000000FF;

    return 0xFF000000 | R | G | B;
}

As others have stated, if you're using a standard java object, just use getRGB();

If you decide to use the android color class properly you can also do:

int RGB = android.graphics.Color.argb(255, Red, Green, Blue); //Where Red, Green, Blue are the RGB components. The number 255 is for 100% Alpha

or

int RGB = android.graphics.Color.rgb(Red, Green, Blue); //Where Red, Green, Blue are the RGB components.

as others have stated... (Second function assumes 100% alpha)

Both methods basically do the same thing as the first method created above.

Could anybody post a working solution for doing this in the terminal?

ANDROID_HOME is usually a directory like .android. Its where things like the Debug Key will be stored.

export ANDROID_HOME=~/.android 

You can automate it for your login. Just add it to your .bash_profile (below is from my OS X 10.8.5 machine):

$ cat ~/.bash_profile
# MacPorts Installer addition on 2012-07-19 at 20:21:05
export PATH=/opt/local/bin:/opt/local/sbin:$PATH

# Android
export ANDROID_NDK_ROOT=/opt/android-ndk-r9
export ANDROID_SDK_ROOT=/opt/android-sdk
export JAVA_HOME=`/usr/libexec/java_home`
export ANDROID_HOME=~/.android

export PATH="$ANDROID_SDK_ROOT/tools/":"$ANDROID_SDK_ROOT/platform-tools/":"$PATH"

According to David Turner on the NDK Mailing List, both ANDROID_NDK_ROOT and ANDROID_SDK_ROOT need to be set because other tools depend on those values (see Recommended NDK Directory?).

After modifying ~/.bash_profile, then perform the following (or logoff and back on):

source ~/.bash_profile

implode or join (they're the exact same thing) would work here. Alternatively, you can just call array_pop and get the value of the only element in the array.

Use Area/Location format properly. Example:

TIME_ZONE = 'Asia/Kolkata'

In case it helps anyone else, using the new Microsoft Web Service Reference Provider tool, which is for .NET Standard and .NET Core, I had to add the following lines to the binding definition as below:

binding.Security.Mode = BasicHttpSecurityMode.Transport;
binding.Security.Transport = new HttpTransportSecurity{ClientCredentialType = HttpClientCredentialType.Certificate};

This is effectively the same as Micha's answer but in code as there is no config file.

So to incorporate the binding with the instantiation of the web service I did this:

 System.ServiceModel.BasicHttpBinding binding = new System.ServiceModel.BasicHttpBinding();
 binding.Security.Mode = System.ServiceModel.BasicHttpSecurityMode.Transport;
 binding.Security.Transport.ClientCredentialType = System.ServiceModel.HttpClientCredentialType.Certificate;
 var client = new WebServiceClient(binding, GetWebServiceEndpointAddress());

Where WebServiceClient is the proper name of your web service as you defined it.

The first parameter of Html.RadioButtonFor() should be the property name you're using, and the second parameter should be the value of that specific radio button. Then they'll have the same name attribute value and the helper will select the given radio button when/if it matches the property value.

Example:

<div class="editor-field">
    <%= Html.RadioButtonFor(m => m.Gender, "M" ) %> Male
    <%= Html.RadioButtonFor(m => m.Gender, "F" ) %> Female
</div>

Here's a more specific example:

I made a quick MVC project named "DeleteMeQuestion" (DeleteMe prefix so I know that I can remove it later after I forget about it).

I made the following model:

namespace DeleteMeQuestion.Models
{
    public class QuizModel
    {
        public int ParentQuestionId { get; set; }
        public int QuestionId { get; set; }
        public string QuestionDisplayText { get; set; }
        public List<Response> Responses { get; set; }

        [Range(1,999, ErrorMessage = "Please choose a response.")]
        public int SelectedResponse { get; set; }
    }

    public class Response
    {
        public int ResponseId { get; set; }
        public int ChildQuestionId { get; set; }
        public string ResponseDisplayText { get; set; }
    }
}

There's a simple range validator in the model, just for fun. Next up, I made the following controller:

namespace DeleteMeQuestion.Controllers
{
    [HandleError]
    public class HomeController : Controller
    {
        public ActionResult Index(int? id)
        {
            // TODO: get question to show based on method parameter 
            var model = GetModel(id);
            return View(model);
        }

        [HttpPost]
        public ActionResult Index(int? id, QuizModel model)
        {
            if (!ModelState.IsValid)
            {
                var freshModel = GetModel(id);
                return View(freshModel);
            }

            // TODO: save selected answer in database
            // TODO: get next question based on selected answer (hard coded to 999 for now)

            var nextQuestionId = 999;
            return RedirectToAction("Index", "Home", new {id = nextQuestionId});
        }

        private QuizModel GetModel(int? questionId)
        {
            // just a stub, in lieu of a database

            var model = new QuizModel
            {
                QuestionDisplayText = questionId.HasValue ? "And so on..." : "What is your favorite color?",
                QuestionId = 1,
                Responses = new List<Response>
                                                {
                                                    new Response
                                                        {
                                                            ChildQuestionId = 2,
                                                            ResponseId = 1,
                                                            ResponseDisplayText = "Red"
                                                        },
                                                    new Response
                                                        {
                                                            ChildQuestionId = 3,
                                                            ResponseId = 2,
                                                            ResponseDisplayText = "Blue"
                                                        },
                                                    new Response
                                                        {
                                                            ChildQuestionId = 4,
                                                            ResponseId = 3,
                                                            ResponseDisplayText = "Green"
                                                        },
                                                }
            };

            return model;
        }
    }
}

Finally, I made the following view that makes use of the model:

<%@ Page Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<DeleteMeQuestion.Models.QuizModel>" %>

<asp:Content ContentPlaceHolderID="TitleContent" runat="server">
    Home Page
</asp:Content>

<asp:Content ContentPlaceHolderID="MainContent" runat="server">

    <% using (Html.BeginForm()) { %>

        <div>

            <h1><%: Model.QuestionDisplayText %></h1>

            <div>
            <ul>
            <% foreach (var item in Model.Responses) { %>
                <li>
                    <%= Html.RadioButtonFor(m => m.SelectedResponse, item.ResponseId, new {id="Response" + item.ResponseId}) %>
                    <label for="Response<%: item.ResponseId %>"><%: item.ResponseDisplayText %></label>
                </li>
            <% } %>
            </ul>

            <%= Html.ValidationMessageFor(m => m.SelectedResponse) %>

        </div>

        <input type="submit" value="Submit" />

    <% } %>

</asp:Content>

As I understand your context, you have questions with a list of available answers. Each answer will dictate the next question. Hopefully that makes sense from my model and TODO comments.

This gives you the radio buttons with the same name attribute, but different ID attributes.

Below is a batch file that will wait for 1 minute, check the day, and then perform an action. It uses PING.EXE, but requires no files that aren't included with Windows.

@ECHO OFF

It could be improved upon in many ways, but it might get you started.

If anybody still wants this, Java regex for support Unicode? is a good one. It's for when you want ONLY letters (no matter what encoding - japaneese, sweedish) iside an EditText. Later, you can check it using Matcher and Pattern.compile()

To combine revision 3 and 4 into a single revision, you can use git rebase. If you want to remove the changes in revision 3, you need to use the edit command in the interactive rebase mode. If you want to combine the changes into a single revision, use squash.

I have successfully used this squash technique, but have never needed to remove a revision before. The git-rebase documentation under "Splitting commits" should hopefully give you enough of an idea to figure it out. (Or someone else might know).

From the git documentation:

Start it with the oldest commit you want to retain as-is:

git rebase -i <after-this-commit>

An editor will be fired up with all the commits in your current branch (ignoring merge commits), which come after the given commit. You can reorder the commits in this list to your heart's content, and you can remove them. The list looks more or less like this:

pick deadbee The oneline of this commit
pick fa1afe1 The oneline of the next commit
...

The oneline descriptions are purely for your pleasure; git-rebase will not look at them but at the commit names ("deadbee" and "fa1afe1" in this example), so do not delete or edit the names.

By replacing the command "pick" with the command "edit", you can tell git-rebase to stop after applying that commit, so that you can edit the files and/or the commit message, amend the commit, and continue rebasing.

If you want to fold two or more commits into one, replace the command "pick" with "squash" for the second and subsequent commit. If the commits had different authors, it will attribute the squashed commit to the author of the first commit.

You could simply add a click listener on the map inside the function that creates the InfoWindow

google.maps.event.addListener(marker, 'click', function() {
    var infoWindow = createInfoWindowForMarker(marker);
    infoWindow.open(map, marker);
    google.maps.event.addListener(map, 'click', function() {
        infoWindow.close();
    });
});

Spent a while on this issue, and the PATH switch wasn't helping. My problem was the Homebrew/node/npm bug found here - https://github.com/npm/npm/issues/3794

If you've already installed node using Homebrew, try ****Note per comments that this might not be safe. It worked for me but could have unintended consequences. It also appears that latest version of Homebrew properly installs npm. So likely I would try brew update, brew doctor, brew upgrade node etc before trying****:

npm update -gf

Or, if you want to install node with Homebrew and have npm work, use:

brew install node --without-npm
curl -L https://npmjs.org/install.sh | sh

If I recall correctly, a div inside a li used to be invalid.

@Flower @Superstringcheese Div should semantically define a section of a document, but it has already practically lost this role. Span should however contain text.

If both of your servers are using WHM, I think we can reduce the time to nil. Create your domain in the new server and set everything ready. Go to the previous server and delete the account corresponding to that domain. Until now I have got no errors by doing this and felt the update instantaneous. FYI I used hostgator hosting (both dedicated servers). And I really dont know why it is so. It's supposed to be not like that until the TTL is over.

How about sed?

hour=`echo $hour|sed -e "s/^0*//g"`

Variation of the code by Bijaya Bidari that is accepted by Java 8 without warnings in regard with overridable method calls in constructor:

public class Graph extends JFrame {
    JPanel jp;

    public Graph() {
        super("Simple Drawing");
        super.setSize(300, 300);
        super.setDefaultCloseOperation(EXIT_ON_CLOSE);

        jp = new GPanel();
        super.add(jp);
    }

    public static void main(String[] args) {
        Graph g1 = new Graph();
        g1.setVisible(true);
    }

    class GPanel extends JPanel {
        public GPanel() {
            super.setPreferredSize(new Dimension(300, 300));
        }

        @Override
        public void paintComponent(Graphics g) {
            super.paintComponent(g);
            //rectangle originated at 10,10 and end at 240,240
            g.drawRect(10, 10, 240, 240);
                    //filled Rectangle with rounded corners.    
            g.fillRoundRect(50, 50, 100, 100, 80, 80);
        }
    }
}

First of all check the declaration of both the methods.

1) OrElse: Execute logic and pass result as argument.

public T orElse(T other) {    
 return value != null ? value : other;
}

2) OrElseGet: Execute logic if value inside the optional is null

public T orElseGet(Supplier<? extends T> other) {
  return value != null ? value : other.get(); 
}

Some explanation on above declaration: The argument of “Optional.orElse” always gets executed irrespective of the value of the object in optional (null, empty or with value). Always consider the above-mentioned point in mind while using “Optional.orElse”, otherwise use of “Optional.orElse” can be very risky in the following situation.

Risk-1) Logging Issue: If content inside orElse contains any log statement: In this case, you will end up logging it every time.

Optional.of(getModel())
   .map(x -> {
      //some logic
   })
  .orElse(getDefaultAndLogError());

getDefaultAndLogError() {
  log.error("No Data found, Returning default");
  return defaultValue;
}

Risk-2) Performance Issue: If content inside orElse is time-intensive: Time intensive content can be any i/o operations DB call, API call, file reading. If we put such content in orElse(), the system will end up executing a code of no use.

Optional.of(getModel())
   .map(x -> //some logic)
   .orElse(getDefaultFromDb());

getDefaultFromDb() {
   return dataBaseServe.getDefaultValue(); //api call, db call.
}

Risk-3) Illegal State or Bug Issue: If content inside orElse is mutating some object state: We might be using the same object at another place let say inside Optional.map function and it can put us in a critical bug.

List<Model> list = new ArrayList<>();
Optional.of(getModel())
  .map(x -> {
  })
  .orElse(get(list));

get(List < String > list) {
   log.error("No Data found, Returning default");
   list.add(defaultValue);
   return defaultValue;
}

Then, When can we go with orElse()? Prefer using orElse when the default value is some constant object, enum. In all above cases we can go with Optional.orElseGet() (which only executes when Optional contains non empty value)instead of Optional.orElse(). Why?? In orElse, we pass default result value, but in orElseGet we pass Supplier and method of Supplier only executes if the value in Optional is null.

Key takeaways from this:

1. Do not use “Optional.orElse” if it contains any log statement.
2. Do not use “Optional.orElse” if it contains time-intensive logic.
3. Do not use “Optional.orElse” if it is mutating some object state.
4. Use “Optional.orElse” if we have to return a constant, enum.
5. Prefer “Optional.orElseGet” in the situations mentioned in 1,2 and 3rd points.

I have explained this in point-2 (“Optional.map/Optional.orElse” != “if/else”) my medium blog. Use Java8 as a programmer not as a coder

In my case new File() doesn't work, it causes a FileNotFoundException when run in a Jenkins pipeline job. The following code solved this, and is even easier in my opinion:

def fileContents = readFile "path/to/file"

I still don't understand this difference completely, but maybe it'll help anyone else with the same trouble. Possibly the exception was caused because new File() creates a file on the system which executes the groovy code, which was a different system than the one that contains the file I wanted to read.

I believe the command you are looking for is passwd

    if (File.Exists(Server.MapPath("~/Images/associates/" + Html.DisplayFor(modelItem => item.AssociateImage)))) 
      { 
        <img src="~/Images/associates/@Html.DisplayFor(modelItem => item.AssociateImage)"> 
      }
        else 
      { 
        <h5>No image available</h5> 
      }

I did something like this for checking to see if an image existed before displaying it.

If you are looking for a custom configuration section like following

<CustomApplicationConfig>
        <Credentials Username="itsme" Password="mypassword"/>
        <PrimaryAgent Address="10.5.64.26" Port="3560"/>
        <SecondaryAgent Address="10.5.64.7" Port="3570"/>
        <Site Id="123" />
        <Lanes>
          <Lane Id="1" PointId="north" Direction="Entry"/>
          <Lane Id="2" PointId="south" Direction="Exit"/>
        </Lanes> 
</CustomApplicationConfig>

then you can use my implementation of configuration section so to get started add System.Configuration assembly reference to your project

Look at the each nested elements I used, First one is Credentials with two attributes so lets add it first

Credentials Element

public class CredentialsConfigElement : System.Configuration.ConfigurationElement
    {
        [ConfigurationProperty("Username")]
        public string Username
        {
            get 
            {
                return base["Username"] as string;
            }
        }

        [ConfigurationProperty("Password")]
        public string Password
        {
            get
            {
                return base["Password"] as string;
            }
        }
    }

PrimaryAgent and SecondaryAgent

Both has the same attributes and seem like a Address to a set of servers for a primary and a failover, so you just need to create one element class for both of those like following

public class ServerInfoConfigElement : ConfigurationElement
    {
        [ConfigurationProperty("Address")]
        public string Address
        {
            get
            {
                return base["Address"] as string;
            }
        }

        [ConfigurationProperty("Port")]
        public int? Port
        {
            get
            {
                return base["Port"] as int?;
            }
        }
    }

I'll explain how to use two different element with one class later in this post, let us skip the SiteId as there is no difference in it. You just have to create one class same as above with one property only. let us see how to implement Lanes collection

it is splitted in two parts first you have to create an element implementation class then you have to create collection element class

LaneConfigElement

public class LaneConfigElement : ConfigurationElement
    {
        [ConfigurationProperty("Id")]
        public string Id
        {
            get
            {
                return base["Id"] as string;
            }
        }

        [ConfigurationProperty("PointId")]
        public string PointId
        {
            get
            {
                return base["PointId"] as string;
            }
        }

        [ConfigurationProperty("Direction")]
        public Direction? Direction
        {
            get
            {
                return base["Direction"] as Direction?;
            }
        }
    }

    public enum Direction
    { 
        Entry,
        Exit
    }

you can notice that one attribute of LanElement is an Enumeration and if you try to use any other value in configuration which is not defined in Enumeration application will throw an System.Configuration.ConfigurationErrorsException on startup. Ok lets move on to Collection Definition

[ConfigurationCollection(typeof(LaneConfigElement), AddItemName = "Lane", CollectionType = ConfigurationElementCollectionType.BasicMap)]
    public class LaneConfigCollection : ConfigurationElementCollection
    {
        public LaneConfigElement this[int index]
        {
            get { return (LaneConfigElement)BaseGet(index); }
            set
            {
                if (BaseGet(index) != null)
                {
                    BaseRemoveAt(index);
                }
                BaseAdd(index, value);
            }
        }

        public void Add(LaneConfigElement serviceConfig)
        {
            BaseAdd(serviceConfig);
        }

        public void Clear()
        {
            BaseClear();
        }

        protected override ConfigurationElement CreateNewElement()
        {
            return new LaneConfigElement();
        }

        protected override object GetElementKey(ConfigurationElement element)
        {
            return ((LaneConfigElement)element).Id;
        }

        public void Remove(LaneConfigElement serviceConfig)
        {
            BaseRemove(serviceConfig.Id);
        }

        public void RemoveAt(int index)
        {
            BaseRemoveAt(index);
        }

        public void Remove(String name)
        {
            BaseRemove(name);
        }

    }

you can notice that I have set the AddItemName = "Lane" you can choose whatever you like for your collection entry item, i prefer to use "add" the default one but i changed it just for the sake of this post.

Now all of our nested Elements have been implemented now we should aggregate all of those in a class which has to implement System.Configuration.ConfigurationSection

CustomApplicationConfigSection

public class CustomApplicationConfigSection : System.Configuration.ConfigurationSection
    {
        private static readonly ILog log = LogManager.GetLogger(typeof(CustomApplicationConfigSection));
        public const string SECTION_NAME = "CustomApplicationConfig";

        [ConfigurationProperty("Credentials")]
        public CredentialsConfigElement Credentials
        {
            get
            {
                return base["Credentials"] as CredentialsConfigElement;
            }
        }

        [ConfigurationProperty("PrimaryAgent")]
        public ServerInfoConfigElement PrimaryAgent
        {
            get
            {
                return base["PrimaryAgent"] as ServerInfoConfigElement;
            }
        }

        [ConfigurationProperty("SecondaryAgent")]
        public ServerInfoConfigElement SecondaryAgent
        {
            get
            {
                return base["SecondaryAgent"] as ServerInfoConfigElement;
            }
        }

        [ConfigurationProperty("Site")]
        public SiteConfigElement Site
        {
            get
            {
                return base["Site"] as SiteConfigElement;
            }
        }

        [ConfigurationProperty("Lanes")]
        public LaneConfigCollection Lanes
        {
            get { return base["Lanes"] as LaneConfigCollection; }
        }
    }

Now you can see that we have two properties with name PrimaryAgent and SecondaryAgent both have the same type now you can easily understand why we had only one implementation class against these two element.

Before you can use this newly invented configuration section in your app.config (or web.config) you just need to tell you application that you have invented your own configuration section and give it some respect, to do so you have to add following lines in app.config (may be right after start of root tag).

<configSections>
    <section name="CustomApplicationConfig" type="MyNameSpace.CustomApplicationConfigSection, MyAssemblyName" />
  </configSections>

NOTE: MyAssemblyName should be without .dll e.g. if you assembly file name is myDll.dll then use myDll instead of myDll.dll

to retrieve this configuration use following line of code any where in your application

CustomApplicationConfigSection config = System.Configuration.ConfigurationManager.GetSection(CustomApplicationConfigSection.SECTION_NAME) as CustomApplicationConfigSection;

I hope above post would help you to get started with a bit complicated kind of custom config sections.

Happy Coding :)

****Edit**** To Enable LINQ on LaneConfigCollection you have to implement IEnumerable<LaneConfigElement>

And Add following implementation of GetEnumerator

public new IEnumerator<LaneConfigElement> GetEnumerator()
        {
            int count = base.Count;
            for (int i = 0; i < count; i++)
            {
                yield return base.BaseGet(i) as LaneConfigElement;
            }
        }

for the people who are still confused about how yield really works read this nice article

Two key points taken from above article are

it doesn’t really end the method’s execution. yield return pauses the method execution and the next time you call it (for the next enumeration value), the method will continue to execute from the last yield return call. It sounds a bit confusing I think… (Shay Friedman)

Yield is not a feature of the .Net runtime. It is just a C# language feature which gets compiled into simple IL code by the C# compiler. (Lars Corneliussen)

you can use ES5 some. Its pretty first by using callback

function findRestaurent(foodType) {
    var restaurant;
    restaurants.some(function (r) {
        if (r.food === id) {
            restaurant = r;
            return true;
        }
   });
  return restaurant;
}

I'm going to assume that you know the path and filename of the image that you want to upload. Add this string to your NameValuePair using image as the key-name.

Sending images can be done using the HttpComponents libraries. Download the latest HttpClient (currently 4.0.1) binary with dependencies package and copy apache-mime4j-0.6.jar and httpmime-4.0.1.jar to your project and add them to your Java build path.

You will need to add the following imports to your class.

import org.apache.http.entity.mime.HttpMultipartMode;
import org.apache.http.entity.mime.MultipartEntity;
import org.apache.http.entity.mime.content.FileBody;
import org.apache.http.entity.mime.content.StringBody;

Now you can create a MultipartEntity to attach an image to your POST request. The following code shows an example of how to do this:

public void post(String url, List<NameValuePair> nameValuePairs) {
    HttpClient httpClient = new DefaultHttpClient();
    HttpContext localContext = new BasicHttpContext();
    HttpPost httpPost = new HttpPost(url);

    try {
        MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);

        for(int index=0; index < nameValuePairs.size(); index++) {
            if(nameValuePairs.get(index).getName().equalsIgnoreCase("image")) {
                // If the key equals to "image", we use FileBody to transfer the data
                entity.addPart(nameValuePairs.get(index).getName(), new FileBody(new File (nameValuePairs.get(index).getValue())));
            } else {
                // Normal string data
                entity.addPart(nameValuePairs.get(index).getName(), new StringBody(nameValuePairs.get(index).getValue()));
            }
        }

        httpPost.setEntity(entity);

        HttpResponse response = httpClient.execute(httpPost, localContext);

}

I hope this helps you a bit in the right direction.

If you want to avoid closures, and happy to use facades, the following keeps things nice and clean:

try {
    \DB::beginTransaction();

    $user = \Auth::user();
    $user->fill($request->all());
    $user->push();

    \DB::commit();

} catch (Throwable $e) {
    \DB::rollback();
}

If any statements fail, commit will never hit, and the transaction won't process.

If the dates are in the index then simply:

df['20160101':'20160301']

Or you could just open the page in maintenance mode and delete the offending web part.

Sharepoint 2007 Insight: Remove bad or broken web parts from a page

There's no ALTER COLUMN in sqlite.

I believe your only option is to:

• Rename the table to a temporary name
• Create a new table without the NOT NULL constraint
• Copy the content of the old table to the new one
• Remove the old table

This other Stackoverflow answer explains the process in details

Any component added to the GridLayout will be resized to the same size as the largest component added. If you want a component to remain at its preferred size, then wrap that component in a JPanel and then the panel will be resized:

JPanel displayPanel = new JPanel(new GridLayout(4, 2)); 
JTextField titleText = new JTextField("title"); 
JPanel wrapper = new JPanel( new FlowLayout(0, 0, FlowLayout.LEADING) );
wrapper.add( titleText );
displayPanel.add(wrapper); 
//displayPanel.add(titleText); 

For fpdf to work properly, there cannot be any output at all beside what fpdf generates. For example, this will work:

<?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>

While this will not (note the leading space before the opening <? tag)

 <?php
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>

Also, this will not work either (the echo will break it):

<?php
echo "About to create pdf";
$pdf = new FPDF();
$pdf->AddPage();
$pdf->SetFont('Arial','B',16);
$pdf->Cell(40,10,'Hello World!');
$pdf->Output();
?>

I'm not sure about the drupal side of things, but I know that absolutely zero non-fpdf output is a requirement for fpdf to work.

add ob_start (); at the top and at the end add ob_end_flush();

<?php
    ob_start();
    require('fpdf.php');
    $pdf = new FPDF();
    $pdf->AddPage();
    $pdf->SetFont('Arial','B',16);
    $pdf->Cell(40,10,'Hello World!');
    $pdf->Output();
    ob_end_flush(); 
?>

give me an error as below:
FPDF error: Some data has already been output, can't send PDF

to over come this error: go to fpdf.php in that,goto line number 996

function Output($name='', $dest='')

after that make changes like this:

function Output($name='', $dest='') {   
    ob_clean();     //Output PDF to so

Hi do you have a session header on the top of your page. or any includes If you have then try to add this codes on top pf your page it should works fine.

<?

while (ob_get_level())
ob_end_clean();
header("Content-Encoding: None", true);

?>

cheers :-)

In my case i had set:

ini_set('display_errors', 'on');
error_reporting(E_ALL | E_STRICT);

When i made the request to generate the report, some warnings were displayed in the browser (like the usage of deprecated functions).
Turning off the display_errors option, the report was generated successfully.

This will give you the time you want (eg: 21:31 PM)

//Add 2 Hours to just TIME
SimpleDateFormat formatter = new SimpleDateFormat("HH:mm:ss a");
Date date2 = formatter.parse("19:31:51 PM");
Calendar cal2 = Calendar.getInstance();
cal2.setTime(date2);
cal2.add(Calendar.HOUR_OF_DAY, 2);
SimpleDateFormat printTimeFormat = new SimpleDateFormat("HH:mm a");
System.out.println(printTimeFormat.format(cal2.getTime())); 

Just improvised mVChr code

$(".sidebar").css('position', 'fixed')

    var windw = this;

    $.fn.followTo = function(pos) {
        var $this = this,
                $window = $(windw);

        $window.scroll(function(e) {
            if ($window.scrollTop() > pos) {
                topPos = pos + $($this).height();
                $this.css({
                    position: 'absolute',
                    top: topPos
                });
            } else {
                $this.css({
                    position: 'fixed',
                    top: 250 //set your value
                });
            }
        });
    };

    var height = $("body").height() - $("#footer").height() ;
    $('.sidebar').followTo(height);
    $('.sidebar').scrollTo($('html').offset().top);

Another way similar to the yglodt's

In application.properties:

spring.jpa.properties.hibernate.current_session_context_class=org.springframework.orm.hibernate4.SpringSessionContext

And in your configuration class:

@Bean
public SessionFactory sessionFactory(HibernateEntityManagerFactory hemf) {
    return hemf.getSessionFactory();
}

Then you can autowire the SessionFactory in your services as usual:

@Autowired
private SessionFactory sessionFactory;

You need to have the file /root/test/devenv/openstack-rhel/pom.xml

This file need to have the followings elements:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>org.openstack</groupId>
    <artifactId>openstack-rhel-rpms</artifactId>
    <version>2012.1-SNAPSHOT</version>
    <packaging>pom</packaging>
</project>

If you just need to search for one string within another, use the index function (or rindex if you want to start scanning from the end of the string):

if (index($string, $substring) != -1) {
   print "'$string' contains '$substring'\n";
}

To search a string for a pattern match, use the match operator m//:

if ($string =~ m/pattern/) {
    print "'$string' matches the pattern\n";       
}

For mongo v3.6.3+ (or 2019 versions)

rm /var/lib/mongodb/mongod.lock
service mongodb restart

If you are using PHP you can use this, and I'm sure it's almost similar in other languages as well

$WebsiteURL = "https://api.telegram.org/bot".$BotToken;
$text = "<b>This</b> <i>is some Text</i>";
$Update = file_get_contents($WebsiteURL."/sendMessage?chat_id=$chat_id&text=$text&parse_mode=html);

echo $Update;

Here is the list of all tags that you can use

<b>bold</b>, <strong>bold</strong>
<i>italic</i>, <em>italic</em>
<a href="http://www.example.com/">inline URL</a>
<code>inline fixed-width code</code>
<pre>pre-formatted fixed-width code block</pre>

Here is Genaric function for add any number of leading zeros for making any size of numeric string.

function add_zero(your_number, length) {
    var num = '' + your_number;
    while (num.length < length) {
        num = '0' + num;
    }
    return num;
}

Instead of #error, try redefining the macro, just before it is being used. Compilation will fail and compiler will provide the current value it thinks applies to the macro.

#define BOOST_VERSION blah

Using generics (as in the above answers) is your best bet here. I've just double checked and:

test.put("test", arraylistone); 
ArrayList current = new ArrayList();
current = (ArrayList) test.get("test");

will work as well, through I wouldn't recommend it as the generics ensure that only the correct data is added, rather than trying to do the handling at retrieval time.

@ts-expect-error

TS 3.9 introduces a new magic comment. @ts-expect-error will:

• have same functionality as @ts-ignore
• trigger an error, if actually no compiler error has been suppressed (= indicates useless flag)

if (false) {
  // @ts-expect-error: Let's ignore a single compiler error like this unreachable code 
  console.log("hello"); // compiles
}

// If @ts-expect-error didn't suppress anything at all, we now get a nice warning 
let flag = true;
// ...
if (flag) {
  // @ts-expect-error
  // ^~~~~~~~~~~~~~~^ error: "Unused '@ts-expect-error' directive.(2578)"
  console.log("hello"); 
}

Alternatives

@ts-ignore and @ts-expect-error can be used for all sorts of compiler errors. For type issues (like in OP), I recommend one of the following alternatives due to narrower error suppression scope:

? Use any type

// type assertion for single expression
delete ($ as any).summernote.options.keyMap.pc.TAB;

// new variable assignment for multiple usages
const $$: any = $
delete $$.summernote.options.keyMap.pc.TAB;
delete $$.summernote.options.keyMap.mac.TAB;

? Augment JQueryStatic interface

// ./global.d.ts
interface JQueryStatic {
  summernote: any;
}

// ./main.ts
delete $.summernote.options.keyMap.pc.TAB; // works

In other cases, shorthand module declarations or module augmentations for modules with no/extendable types are handy utilities. A viable strategy is also to keep not migrated code in .js and use --allowJs with checkJs: false.

You must specify that the friend is a template function:

MyClass<T>& operator+=<>(const MyClass<T>& classObj);

See this C++ FAQ Lite answer for details.

Just special-case it. If you see a numerator of 0 and a denominator of 0, pretend like it has the values you really want.

Answered my own question. Sigh

I didn't realize it was passed into the widget constructor.

Convert the argument to int. It's as simple as

int(argument)

All I needed was:

cd /etc/apt
nano source.list
deb http://http.kali.org/kali kali-rolling main non-free contrib

apt upgrade && update

Somewhat similar to your original attempt, but more Pythonic, is to use Python's standard negative-indexing convention to count backwards from the end:

df[df.columns[-1]]

You can script it with a tool like expect (there are handy bindings too, like Pexpect for Python).

You could use Role Strategy plugin for that purpose. It works like a charm, just setup some roles and assign them. Even on project-specific level.

Let your callback return false and pass that on to the onclick handler:

<a href="#" onclick="return callmymethod(24)">Call</a>

function callmymethod(myVal){
    //doing custom things with myVal
    //here I want to prevent default
    return false;
}

To create maintainable code, however, you should abstain from using "inline Javascript" (i.e.: code that's directly within an element's tag) and modify an element's behavior via an included Javascript source file (it's called unobtrusive Javascript).

The mark-up:

<a href="#" id="myAnchor">Call</a>

The code (separate file):

// Code example using Prototype JS API
$('myAnchor').observe('click', function(event) {
    Event.stop(event); // suppress default click behavior, cancel the event
    /* your onclick code goes here */
});

Go to the Declaration of the desired object and mark it Shared.

Friend Shared WithEvents MyGridCustomer As Janus.Windows.GridEX.GridEX

Difference is static variables are those variables: which allows a value to be retained from one call of the function to another. But in case of local variables the scope is till the block/ function lifetime.

For Example:

#include <stdio.h>

void func() {
    static int x = 0; // x is initialized only once across three calls of func()
    printf("%d\n", x); // outputs the value of x
    x = x + 1;
}

int main(int argc, char * const argv[]) {
    func(); // prints 0
    func(); // prints 1
    func(); // prints 2
    return 0;
}

From the HERE and HERE

public File getFilesDir ()

Returns the absolute path to the directory on the filesystem where files created with openFileOutput(String, int) are stored.

public static File getExternalStorageDirectory ()

Return the primary external storage directory. This directory may not currently be accessible if it has been mounted by the user on their computer, has been removed from the device, or some other problem has happened. You can determine its current state with getExternalStorageState().

Note: don't be confused by the word "external" here. This directory can better be thought as media/shared storage. It is a filesystem that can hold a relatively large amount of data and that is shared across all applications (does not enforce permissions). Traditionally this is an SD card, but it may also be implemented as built-in storage in a device that is distinct from the protected internal storage and can be mounted as a filesystem on a computer.

On devices with multiple users (as described by UserManager), each user has their own isolated external storage. Applications only have access to the external storage for the user they're running as.

If you want to get your application path use getFilesDir() which will give you path /data/data/your package/files

You can get the path using the Environment var of your data/package using the

getExternalFilesDir(Environment.getDataDirectory().getAbsolutePath()).getAbsolutePath(); which will return the path from the root directory of your external storage as /storage/sdcard/Android/data/your pacakge/files/data

To access the external resources you have to provide the permission of WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE in your manifest.

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

The short answer is that the --dbpath parameter in MongoDB will allow you to control what directory MongoDB reads and writes it's data from.

mongod --dbpath /usr/local/mongodb-data

Would start mongodb and put the files in /usr/local/mongodb-data.

Depending on your distribution and MongoDB installation, you can also configure the mongod.conf file to do this automatically:

# Store data in /usr/local/var/mongodb instead of the default /data/db
dbpath = /usr/local/var/mongodb

The official 10gen Linux packages (Ubuntu/Debian or CentOS/Fedora) ship with a basic configuration file which is placed in /etc/mongodb.conf, and the MongoDB service reads this when it starts up. You could make your change here.

java.time

UPDATE

The other Questions are outmoded. The terrible legacy classes such as SimpleDateFormat were supplanted years ago by the modern java.time classes.

Custom

For defining your own custom formatting patterns, the codes in DateTimeFormatter are similar to but not exactly the same as the codes in SimpleDateFormat. Be sure to study the documentation. And search Stack Overflow for many examples.

DateTimeFormatter f = 
    DateTimeFormatter.ofPattern( 
        "dd MMM uuuu" , 
        Locale.ITALY 
    ) 
;

Standard ISO 8601

The ISO 8601 standard defines formats for many types of date-time values. These formats are designed for data-exchange, being easily parsed by machine as well as easily read by humans across cultures.

The java.time classes use ISO 8601 formats by default when generating/parsing strings. Simply call the toString & parse methods. No need to specify a formatting pattern.

Instant.now().toString()

2018-11-05T18:19:33.017554Z

For a value in UTC, the Z on the end means UTC, and is pronounced “Zulu”.

Localize

Rather than specify a formatting pattern, you can let java.time automatically localize for you. Use the DateTimeFormatter.ofLocalized… methods.

Get current moment with the wall-clock time used by the people of a particular region (a time zone).

ZoneId z = ZoneId.of( "Africa/Tunis" );
ZonedDateTime zdt = ZonedDateTime.now( z );

Generate text in standard ISO 8601 format wisely extended to append the name of the time zone in square brackets.

zdt.toString(): 2018-11-05T19:20:23.765293+01:00[Africa/Tunis]

Generate auto-localized text.

Locale locale = Locale.CANADA_FRENCH;
DateTimeFormatter f = DateTimeFormatter.ofLocalizedDateTime( FormatStyle.FULL ).withLocale( locale );

String output = zdt.format( f );

output: lundi 5 novembre 2018 à 19:20:23 heure normale d’Europe centrale

Generally a better practice to auto-localize rather than fret with hard-coded formatting patterns.

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.

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

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

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. Hibernate 5 & JPA 2.2 support java.time.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 brought some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android (26+) bundle implementations of the java.time classes.
  • For earlier Android (<26), a process known as API desugaring brings a subset of the java.time functionality not originally built into Android.
    • If the desugaring does not offer what you need, the ThreeTenABP project adapts ThreeTen-Backport (mentioned above) to Android. See How to use ThreeTenABP….

Try this:

static void Main(string[] args)
{
    var dt = new DataTable
    {
        Columns = { { "Lastname",typeof(string) }, { "Firstname",typeof(string) } }
    };
    dt.Rows.Add("Lennon", "John");
    dt.Rows.Add("McCartney", "Paul");
    dt.Rows.Add("Harrison", "George");
    dt.Rows.Add("Starr", "Ringo");

    List<string> s = dt.AsEnumerable().Select(x => x[0].ToString()).ToList();

    foreach(string e in s)
        Console.WriteLine(e);

    Console.ReadLine();
}

in case files have no extension we can look for file mime type

find . -type f -exec file -i {} + | awk -F': +' '{ if ($2 ~ /audio|video|matroska|mpeg/) print $1 }'

where (audio|video|matroska|mpeg) are mime types regex

&if you want to delete them:

find . -type f -exec file -i {} + | awk -F': +' '{ if ($2 ~ /audio|video|matroska|mpeg/) print $1 }' | while read f ; do
  rm "$f"
done

or delete everything else but those extensions:

find . -type f -exec file -i {} + | awk -F': +' '{ if ($2 !~ /audio|video|matroska|mpeg/) print $1 }' | while read f ; do
  rm "$f"
done

notice the !~ instead of ~

Here's a shorter version you can now use to turn the light on or off:

AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
if ([device hasTorch]) {
    [device lockForConfiguration:nil];
    [device setTorchMode:AVCaptureTorchModeOn];  // use AVCaptureTorchModeOff to turn off
    [device unlockForConfiguration];
}

UPDATE: (March 2015)

With iOS 6.0 and later, you can control the brightness or level of the torch using the following method:

- (void)setTorchToLevel:(float)torchLevel
{
    AVCaptureDevice *device = [AVCaptureDevice defaultDeviceWithMediaType:AVMediaTypeVideo];
    if ([device hasTorch]) {
        [device lockForConfiguration:nil];
        if (torchLevel <= 0.0) {
            [device setTorchMode:AVCaptureTorchModeOff];
        }
        else {
            if (torchLevel >= 1.0)
                torchLevel = AVCaptureMaxAvailableTorchLevel;
            BOOL success = [device setTorchModeOnWithLevel:torchLevel   error:nil];
        }
        [device unlockForConfiguration];
    }
}

You may also want to monitor the return value (success) from setTorchModeOnWithLevel:. You may get a failure if you try to set the level too high and the torch is overheating. In that case setting the level to AVCaptureMaxAvailableTorchLevel will set the level to the highest level that is allowed given the temperature of the torch.

As @etal said, rebooting can solve this problem, but I think a procedure without rebooting will help.

For Chinese, check my blog -> ???

The error message

NVML: Driver/library version mismatch

tell us the Nvidia driver kernel module (kmod) have a wrong version, so we should unload this driver, and then load the correct version of kmod

How to do that ?

First, we should know which drivers are loaded.

lsmod | grep nvidia

you may get

nvidia_uvm            634880  8
nvidia_drm             53248  0
nvidia_modeset        790528  1 nvidia_drm
nvidia              12312576  86 nvidia_modeset,nvidia_uvm

our final goal is to unload nvidia mod, so we should unload the module depend on nvidia

sudo rmmod nvidia_drm
sudo rmmod nvidia_modeset
sudo rmmod nvidia_uvm

then, unload nvidia

sudo rmmod nvidia

Troubleshooting

if you get an error like rmmod: ERROR: Module nvidia is in use, which indicates that the kernel module is in use, you should kill the process that using the kmod:

sudo lsof /dev/nvidia*

and then kill those process, then continue to unload the kmods

Test

confirm you successfully unload those kmods

lsmod | grep nvidia

you should get nothing, then confirm you can load the correct driver

nvidia-smi

you should get the correct output

The stringr package provides the str_sub function, which is a bit easier to use than substr, especially if you want to extract right portions of your string :

R> str_sub("leftright",1,4)
[1] "left"
R> str_sub("leftright",-5,-1)
[1] "right"

If you just want to re-load/update dependencies (I assume, with constantly changing you mean either SNAPSHOTS or local dependencies you update yourself), you can use

mvn dependency:resolve

There are 2 issues with your code:

1. The result is stored in int which can handle only a first 48 fibonacci numbers, after this the integer fill minus bit and result is wrong.
2. But you never can run fibonacci(50).
   The code
   fibonacci(n - 1) + fibonacci(n - 2)
   is very wrong.
   The problem is that the it calls fibonacci not 50 times but much more.
   At first it calls fibonacci(49)+fibonacci(48),
   next fibonacci(48)+fibonacci(47) and fibonacci(47)+fibonacci(46)
   Each time it became fibonacci(n) worse, so the complexity is exponential.

The approach to non-recursive code:

 double fibbonaci(int n){
    double prev=0d, next=1d, result=0d;
    for (int i = 0; i < n; i++) {
        result=prev+next;
        prev=next;
        next=result;
    }
    return result;
}
