Programs & Examples On #Goinstall

As of 2020 and Go version 1.13+, in Windows the best way for updating GOPATH is just typing in command prompt:

setx GOPATH C:\mynewgopath

You could use overloads:

public static string BuildClause(List<string> l){...}

public static string BuildClause(List<int> l){...}

public static string BuildClause<T>(List<T> l){...}

Or you could inspect the type of the generic parameter:

Type listType = typeof(T);
if(listType == typeof(int)){...}

Modification to the answer by Justin that works for me:

1. Added img.onload
2. Expand the POST request with a real example

function handleFiles()
{
    var dataurl = null;
    var filesToUpload = document.getElementById('photo').files;
    var file = filesToUpload[0];

    // Create an image
    var img = document.createElement("img");
    // Create a file reader
    var reader = new FileReader();
    // Set the image once loaded into file reader
    reader.onload = function(e)
    {
        img.src = e.target.result;

        img.onload = function () {
            var canvas = document.createElement("canvas");
            var ctx = canvas.getContext("2d");
            ctx.drawImage(img, 0, 0);

            var MAX_WIDTH = 800;
            var MAX_HEIGHT = 600;
            var width = img.width;
            var height = img.height;

            if (width > height) {
              if (width > MAX_WIDTH) {
                height *= MAX_WIDTH / width;
                width = MAX_WIDTH;
              }
            } else {
              if (height > MAX_HEIGHT) {
                width *= MAX_HEIGHT / height;
                height = MAX_HEIGHT;
              }
            }
            canvas.width = width;
            canvas.height = height;
            var ctx = canvas.getContext("2d");
            ctx.drawImage(img, 0, 0, width, height);

            dataurl = canvas.toDataURL("image/jpeg");

            // Post the data
            var fd = new FormData();
            fd.append("name", "some_filename.jpg");
            fd.append("image", dataurl);
            fd.append("info", "lah_de_dah");
            $.ajax({
                url: '/ajax_photo',
                data: fd,
                cache: false,
                contentType: false,
                processData: false,
                type: 'POST',
                success: function(data){
                    $('#form_photo')[0].reset();
                    location.reload();
                }
            });
        } // img.onload
    }
    // Load files into file reader
    reader.readAsDataURL(file);
}

in case you need to use a bool param, you need just to assign the default value.

func test(WithFlag flag: Bool = false){.....}

then you can use without or with the param:

test() //here flag automatically has the default value: false
test(WithFlag: true) //here flag has the value: true

Update : STYLE GUIDE is now on Angular docs.

Simpler variant of thelsdj's answer:

ls -tr | head -n -5 | xargs --no-run-if-empty rm 

ls -tr displays all the files, oldest first (-t newest first, -r reverse).

head -n -5 displays all but the 5 last lines (ie the 5 newest files).

xargs rm calls rm for each selected file.

I hit this issue when, for example, mapping one class to another (such as when switching to a new set of classes to represent person data). At that point, you need both classes because that is the whole point of the code--to map one to the other. And you can't rename the classes in either place (again, the job is to map, not to go change what someone else did).

Fully qualified is one way. It appears you can't actually include both import statements, because Java gets worried about which "Person" is meant, for example.

As long as the server allows the ampresand character to be POSTed (not all do as it can be unsafe), all you should have to do is URL Encode the character. In the case of an ampresand, you should replace the character with %26.

.NET provides a nice way of encoding the entire string for you though:

string strNew = "&uploadfile=true&file=" + HttpUtility.UrlEncode(iCalStr);

If you want to do it in plain javascript, you can define a function like this:

var getJSON = function(url, callback) {
    var xhr = new XMLHttpRequest();
    xhr.open('GET', url, true);
    xhr.responseType = 'json';
    xhr.onload = function() {
      var status = xhr.status;
      if (status === 200) {
        callback(null, xhr.response);
      } else {
        callback(status, xhr.response);
      }
    };
    xhr.send();
};

And use it like this:

getJSON('http://query.yahooapis.com/v1/public/yql?q=select%20%2a%20from%20yahoo.finance.quotes%20WHERE%20symbol%3D%27WRC%27&format=json&diagnostics=true&env=store://datatables.org/alltableswithkeys&callback',
function(err, data) {
  if (err !== null) {
    alert('Something went wrong: ' + err);
  } else {
    alert('Your query count: ' + data.query.count);
  }
});

Note that data is an object, so you can access its attributes without having to parse it.

I am guessing you are trying to mix Asp code and JS code and at some point it's breaking or not excusing the binding calls correctly.

Perhaps you can try using a delegate instead. It will cut out the complexity of when to bind the click event.

An example would be:

$('body').delegate('.menu li','click',function(){
   var $li = $(this);

   var shouldAddClass = $li.find('a[href^="www.xyz.com/link1"]').length != 0;

   if(shouldAddClass){
       $li.addClass('active');
   }
});

See if that helps, it uses the Attribute Starts With Selector from jQuery.

The pack syntax you are using here is for an image that is contained as a Resource within your application, not for a loose file in the file system.

You simply want to pass the actual path to the UriSource:

logo.UriSource = new Uri(@"\\myserver\folder1\Customer Data\sample.png");

I solved this problem by programmatically creating the Labels and Textfields, and then Command-Dragged from the little empty circles on the left of the code to the components on the Storyboard. To illustrate my point: I wrote @IBOutlet weak var HelloLabel: UILabel!, and then pressed Command and dragged the code into the component on the storyboard.

I think what you want is this:

last_list=[]
if p.last_name != None and p.last_name != "":
    last_list.append(p.last_name)
print last_list

Your current if statement:

if p.last_name == None or p.last_name == "":
    pass

Effectively never does anything. If p.last_name is none or the empty string, it does nothing inside the loop. If p.last_name is something else, the body of the if statement is skipped.

Also, it looks like your statement pan_list.append(p.last) is a typo, because I see neither pan_list nor p.last getting used anywhere else in the code you have posted.

array.split(' ').slice(-1)[0]

The best one ever and my favorite.

You can do:

>>> a = 'ZENOVW'
>>> ''.join(sorted(a))
'ENOVWZ'

This question's bit old, but, there's a tricky scenario which also leads to this error:

In controller:

ViewBag.id = //id from querystring
List<string> = GrabDataFromDBByID(ViewBag.id).Select(a=>a.ToString());

The above code will lead to an error in this part: .Select(a=>a.ToString()) because of the below reason: You're passing a ViewBag.id to a method which in compiler, it doesn't know the type, so there might be several methods with the same name and different parameters let's say:

GrabDataFromDBByID(string)
GrabDataFromDBByID(int)
GrabDataFromDBByID(whateverType)

So to prevent this case, either explicitly cast the ViewBag or create another variable storing it.

SELECT IF((
     SELECT count(*) FROM gdata_calendars 
     WHERE `group` =  ? AND id = ?)
,1,0);

There is another way,

j3 = j2 > 4; print(j2[j3])

tested in 3.x

Good question.

• @@IDENTITY: returns the last identity value generated on your SQL connection (SPID). Most of the time it will be what you want, but sometimes it isn't (like when a trigger is fired in response to an INSERT, and the trigger executes another INSERT statement).

• SCOPE_IDENTITY(): returns the last identity value generated in the current scope (i.e. stored procedure, trigger, function, etc).

• IDENT_CURRENT(): returns the last identity value for a specific table. Don't use this to get the identity value from an INSERT, it's subject to race conditions (i.e. multiple connections inserting rows on the same table).

• IDENTITY(): used when declaring a column in a table as an identity column.

For more reference, see: http://msdn.microsoft.com/en-us/library/ms187342.aspx.

To summarize: if you are inserting rows, and you want to know the value of the identity column for the row you just inserted, always use SCOPE_IDENTITY().

You are logging sup directly which is a string

console.log('sup')

Also you are using the wrong id

The template says #main_search but you are using #searchBar

I suppose you are trying this out

$(function() {
   var sup = $('#main_search').val('hi')
   console.log(sup);  // sup is a variable here
});

Before you use scan, make sure that the requested page's Content-Type header is text/html, since there can be links to things like images which are not encoded in UTF-8. The page could also be non-html if you picked up a href in something like a <link> element. How to check this varies on what HTTP library you are using. Then, make sure the result is only ascii with String#ascii_only? (not UTF-8 because HTML is only supposed to be using ascii, entities can be used otherwise). If both of those tests pass, it is safe to use scan.

You can use the fromstring() method for this:

arr = np.array([1, 2, 3, 4, 5, 6])
ts = arr.tostring()
print(np.fromstring(ts, dtype=int))

>>> [1 2 3 4 5 6]

Sorry for the short answer, not enough points for commenting. Remember to state the data types or you'll end up in a world of pain.

Note on fromstring from numpy 1.14 onwards:

sep : str, optional

The string separating numbers in the data; extra whitespace between elements is also ignored.

Deprecated since version 1.14: Passing sep='', the default, is deprecated since it will trigger the deprecated binary mode of this function. This mode interprets string as binary bytes, rather than ASCII text with decimal numbers, an operation which is better spelt frombuffer(string, dtype, count). If string contains unicode text, the binary mode of fromstring will first encode it into bytes using either utf-8 (python 3) or the default encoding (python 2), neither of which produce sane results.

You don't need an index match formula. You can use this array formula. You have to press CTL + SHIFT + ENTER after you enter the formula.

=MAX(IF((A1:A6=A10)*(B1:B6=B10),C1:F6))

SNAPSHOT

You need to break;, throw, goto, or return from each of your case labels. In a loop you may also continue.

        switch (searchType)
        {
            case "SearchBooks":
                Selenium.Type("//*[@id='SearchBooks_TextInput']", searchText);
                Selenium.Click("//*[@id='SearchBooks_SearchBtn']");
                break;

            case "SearchAuthors":
                Selenium.Type("//*[@id='SearchAuthors_TextInput']", searchText);
                Selenium.Click("//*[@id='SearchAuthors_SearchBtn']");
                break;
        }

The only time this isn't true is when the case labels are stacked like this:

 case "SearchBooks": // no code inbetween case labels.
 case "SearchAuthors":
    // handle both of these cases the same way.
    break;

Trying to use a dispatch_semaphore. It should look something like this:

dispatch_semaphore_t sema = dispatch_semaphore_create(0);

[object runSomeLongOperationAndDo:^{
    STAssert…

    dispatch_semaphore_signal(sema);
}];

if (![NSThread isMainThread]) {
    dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
} else {
    while (dispatch_semaphore_wait(sema, DISPATCH_TIME_NOW)) { 
        [[NSRunLoop currentRunLoop] runMode:NSDefaultRunLoopMode beforeDate:[NSDate dateWithTimeIntervalSinceNow:0]]; 
    }
}

This should behave correctly even if runSomeLongOperationAndDo: decides that the operation isn't actually long enough to merit threading and runs synchronously instead.

Try this one:

   $("div.subtab_left li.notebook a").click(function(e) {
    e.preventDefault();
    return false;   
    });

The standard approach is to use sprintf(buffer, "%lu", value); to write a string rep of value to buffer. However, overflow is a potential problem, as sprintf will happily (and unknowingly) write over the end of your buffer.

This is actually a big weakness of sprintf, partially fixed in C++ by using streams rather than buffers. The usual "answer" is to allocate a very generous buffer unlikely to overflow, let sprintf output to that, and then use strlen to determine the actual string length produced, calloc a buffer of (that size + 1) and copy the string to that.

This site discusses this and related problems at some length.

Some libraries offer snprintf as an alternative which lets you specify a maximum buffer size.

Input elements have a property called disabled. When the form submits, just run some code like this:

var myInput = document.getElementById('myInput');
myInput.disabled = true;

In my case, on linux, sudoing fixed the problem.

Example:

sudo gulp dev

This can be another way to do it and validate nulls

DataControlField dataControlField = UsersGrid.Columns.Cast<DataControlField>().SingleOrDefault(x => x.HeaderText == "Email");
            if (dataControlField != null)
                dataControlField.Visible = false;

You can always use an attribute selector. The selector itself would look something like:

a[data-item-id=stand-out]

I forgot that I had already an unused labs branch. Deleting it solved my problem:

git branch -d labs
git checkout -b labs/feature

Explanation:

Each name can only be a parent branch or a normal branch, not both. Thats why the branches labs and labs/feature can't exists both at the same time.

The reason: Branches are stored in the file system and there you also can't have a file labs and a directory labs at the same level.

enumerate is what you want:

for i, s in enumerate(S):
    print s, i

if you want to execute ENABLE TRIGGER Directly From Source :

we can't write like this:

Conn.Execute "ENABLE TRIGGER trigger_name ON table_name"

instead, we can write :

Conn.Execute "ALTER TABLE table_name DISABLE TRIGGER trigger_name"

TL;DR

Use [.] instead of \. and [0-9] instead of \d to avoid escaping issues in some languages (like Java).

^{Thanks to the nameless one for originally recognizing this.}

One relatively simple pattern for matching a floating point number is

[+-]?([0-9]*[.])?[0-9]+

This will match:

• 123
• 123.456
• .456

^{See a working example}

If you also want to match 123. (a period with no decimal part), then you'll need a slightly longer expression:

[+-]?([0-9]+([.][0-9]*)?|[.][0-9]+)

^{See pkeller's answer for a fuller explanation of this pattern}

If you want to include non-decimal numbers, such as hex and octal, see my answer to How do I identify if a string is a number?.

If you want to validate that an input is a number (rather than finding a number within the input), then you should surround the pattern with ^ and $, like so:

^[+-]?([0-9]+([.][0-9]*)?|[.][0-9]+)$

Irregular Regular Expressions

"Regular expressions", as implemented in most modern languages, APIs, frameworks, libraries, etc., are based on a concept developed in formal language theory. However, software engineers have added many extensions that take these implementations far beyond the formal definition. So, while most regular expression engines resemble one another, there is actually no standard. For this reason, a lot depends on what language, API, framework or library you are using.

(Incidentally, to help reduce confusion, many have taken to using "regex" or "regexp" to describe these enhanced matching languages. See Is a Regex the Same as a Regular Expression? at RexEgg.com for more information.)

That said, most regex engines (actually, all of them, as far as I know) would accept \.. Most likely, there's an issue with escaping.

The Trouble with Escaping

Some languages have built-in support for regexes, such as JavaScript. For those languages that don't, escaping can be a problem.

This is because you are basically coding in a language within a language. Java, for example, uses \ as an escape character within it's strings, so if you want to place a literal backslash character within a string, you must escape it:

// creates a single character string: "\"
String x = "\\";

However, regexes also use the \ character for escaping, so if you want to match a literal \ character, you must escape it for the regexe engine, and then escape it again for Java:

// Creates a two-character string: "\\"
// When used as a regex pattern, will match a single character: "\"
String regexPattern = "\\\\";

In your case, you have probably not escaped the backslash character in the language you are programming in:

// will most likely result in an "Illegal escape character" error
String wrongPattern = "\.";
// will result in the string "\."
String correctPattern = "\\.";

All this escaping can get very confusing. If the language you are working with supports raw strings, then you should use those to cut down on the number of backslashes, but not all languages do (most notably: Java). Fortunately, there's an alternative that will work some of the time:

String correctPattern = "[.]";

For a regex engine, \. and [.] mean exactly the same thing. Note that this doesn't work in every case, like newline (\\n), open square bracket (\\[) and backslash (\\\\ or [\\]).

A Note about Matching Numbers

(Hint: It's harder than you think)

Matching a number is one of those things you'd think is quite easy with regex, but it's actually pretty tricky. Let's take a look at your approach, piece by piece:

[-+]?

Match an optional - or +

[0-9]*

Match 0 or more sequential digits

\.?

Match an optional .

[0-9]*

Match 0 or more sequential digits

First, we can clean up this expression a bit by using a character class shorthand for the digits (note that this is also susceptible to the escaping issue mentioned above):

[0-9] = \d

I'm going to use \d below, but keep in mind that it means the same thing as [0-9]. (Well, actually, in some engines \d will match digits from all scripts, so it'll match more than [0-9] will, but that's probably not significant in your case.)

Now, if you look at this carefully, you'll realize that every single part of your pattern is optional. This pattern can match a 0-length string; a string composed only of + or -; or, a string composed only of a .. This is probably not what you've intended.

To fix this, it's helpful to start by "anchoring" your regex with the bare-minimum required string, probably a single digit:

\d+

Now we want to add the decimal part, but it doesn't go where you think it might:

\d+\.?\d* /* This isn't quite correct. */

This will still match values like 123.. Worse, it's got a tinge of evil about it. The period is optional, meaning that you've got two repeated classes side-by-side (\d+ and \d*). This can actually be dangerous if used in just the wrong way, opening your system up to DoS attacks.

To fix this, rather than treating the period as optional, we need to treat it as required (to separate the repeated character classes) and instead make the entire decimal portion optional:

\d+(\.\d+)? /* Better. But... */

This is looking better now. We require a period between the first sequence of digits and the second, but there's a fatal flaw: we can't match .123 because a leading digit is now required.

This is actually pretty easy to fix. Instead of making the "decimal" portion of the number optional, we need to look at it as a sequence of characters: 1 or more numbers that may be prefixed by a . that may be prefixed by 0 or more numbers:

(\d*\.)?\d+

Now we just add the sign:

[+-]?(\d*\.)?\d+

Of course, those slashes are pretty annoying in Java, so we can substitute in our long-form character classes:

[+-]?([0-9]*[.])?[0-9]+

Matching versus Validating

This has come up in the comments a couple times, so I'm adding an addendum on matching versus validating.

The goal of matching is to find some content within the input (the "needle in a haystack"). The goal of validating is to ensure that the input is in an expected format.

Regexes, by their nature, only match text. Given some input, they will either find some matching text or they will not. However, by "snapping" an expression to the beginning and ending of the input with anchor tags (^ and $), we can ensure that no match is found unless the entire input matches the expression, effectively using regexes to validate.

The regex described above ([+-]?([0-9]*[.])?[0-9]+) will match one or more numbers within a target string. So given the input:

apple 1.34 pear 7.98 version 1.2.3.4

The regex will match 1.34, 7.98, 1.2, .3 and .4.

To validate that a given input is a number and nothing but a number, "snap" the expression to the start and end of the input by wrapping it in anchor tags:

^[+-]?([0-9]*[.])?[0-9]+$

This will only find a match if the entire input is a floating point number, and will not find a match if the input contains additional characters. So, given the input 1.2, a match will be found, but given apple 1.2 pear no matches will be found.

Note that some regex engines have a validate, isMatch or similar function, which essentially does what I've described automatically, returning true if a match is found and false if no match is found. Also keep in mind that some engines allow you to set flags which change the definition of ^ and $, matching the beginning/end of a line rather than the beginning/end of the entire input. This is typically not the default, but be on the lookout for these flags.

It depends. If it's a dynamically allocated array, that is, you created it calling malloc, then as others suggest you must either save the size of the array/number of elements somewhere or have a sentinel (a struct with a special value, that will be the last one).

If it's a static array, you can sizeof it's size/the size of one element. For example:

int array[10], array_size;
...
array_size = sizeof(array)/sizeof(int);

Note that, unless it's global, this only works in the scope where you initialized the array, because if you past it to another function it gets decayed to a pointer.

Hope it helps.

I use an alpha-transparent PNG for that:

div.semi-transparent {
  background: url('semi-transparent.png');
}

For IE6, you'd need to use a PNG fix (1, 2), though.

Maybe good ol' cfront will do?

The \includegraphics function has a page option for inserting a specific page of a PDF file as graphs. The default is one, but you can change it.

\includegraphics[scale=0.75,page=2]{multipage.pdf}

You can find more here.

There should be a default active record behavior on this I reckon. Querying dates is hard, especially when timezones are involved.

Anyway, I use:

  scope :between, ->(start_date=nil, end_date=nil) {
    if start_date && end_date
      where("#{self.table_name}.created_at BETWEEN :start AND :end", start: start_date.beginning_of_day, end: end_date.end_of_day)
    elsif start_date
      where("#{self.table_name}.created_at >= ?", start_date.beginning_of_day)
    elsif end_date
      where("#{self.table_name}.created_at <= ?", end_date.end_of_day)
    else
      all
    end
  }

If you have a repository that was cloned with --depth 1 then many of the commands that were listed will not work. For example, see here

In this case I would reclone the repository, but perhaps there are other techniques e.g. git shallow clone (clone --depth) misses remote branches

you need to add Content-Disposition header, smth like this (although I used mod-python here, but principle should be the same):

request.headers_out['Content-Disposition'] = 'attachment; filename=%s' % myfname

When using the Hibernate implementation of JPA , I've found that simply declaring the type as an ArrayList instead of List allows hibernate to store the list of data.

Clearly this has a number of disadvantages compared to creating a list of Entity objects. No lazy loading, no ability to reference the entities in the list from other objects, perhaps more difficulty in constructing database queries. However when you are dealing with lists of fairly primitive types that you will always want to eagerly fetch along with the entity, then this approach seems fine to me.

@Entity
public class Command implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    Long id;

    ArrayList<String> arguments = new ArrayList<String>();


}

I just put them in their own file and export it for node and webpack:

// lodash-cherries.js
module.exports = {
  defaults: require('lodash/defaults'),
  isNil: require('lodash/isNil'),
  isObject: require('lodash/isObject'),
  isArray: require('lodash/isArray'),
  isFunction: require('lodash/isFunction'),
  isInteger: require('lodash/isInteger'),
  isBoolean: require('lodash/isBoolean'),
  keys: require('lodash/keys'),
  set: require('lodash/set'),
  get: require('lodash/get'),
}

Based on your comments in this answer, I do what you're trying to do like this:

module.exports = function (app, db) {
    var module = {};

    module.auth = function (req, res) {
        // This will be available 'outside'.
        // Authy stuff that can be used outside...
    };

    // Other stuff...
    module.pickle = function(cucumber, herbs, vinegar) {
        // This will be available 'outside'.
        // Pickling stuff...
    };

    function jarThemPickles(pickle, jar) {
        // This will be NOT available 'outside'.
        // Pickling stuff...

        return pickleJar;
    };

    return module;
};

I structure pretty much all my modules like that. Seems to work well for me.

@Peter: This could work out for you-

echo "Start!";for p in $(cat ./pep); do
echo $p
done

This would return the output-

Start!

You can escape the dot and other special characters using \

eg. grep -r "0\.49"

Following two steps worked perfectly fine for me:

1. Comment out the bind address from the file /etc/mysql/my.cnf:

   #bind-address = 127.0.0.1

2. Run following query in phpMyAdmin:

   GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'; FLUSH PRIVILEGES;

I think lucene syntax is supported so:

http://localhost:9200/foo/_search?pretty=true&q=*:*

size defaults to 10, so you may also need &size=BIGNUMBER to get more than 10 items. (where BIGNUMBER equals a number you believe is bigger than your dataset)

BUT, elasticsearch documentation suggests for large result sets, using the scan search type.

EG:

curl -XGET 'localhost:9200/foo/_search?search_type=scan&scroll=10m&size=50' -d '
{
    "query" : {
        "match_all" : {}
    }
}'

and then keep requesting as per the documentation link above suggests.

EDIT: scan Deprecated in 2.1.0.

scan does not provide any benefits over a regular scroll request sorted by _doc. link to elastic docs (spotted by @christophe-roussy)

You just can use doStuff($event) in your markup and get the data-attribute values via currentTarget.getAttribute("data-id")) in angular. HTML:

<div ng-controller="TestCtrl">
    <button data-id="345" ng-click="doStuff($event)">Button</button>
</div>

JS:

var app = angular.module("app", []);
app.controller("TestCtrl", function ($scope) {
    $scope.doStuff = function (item) {
        console.log(item.currentTarget);
        console.log(item.currentTarget.getAttribute("data-id"));
    };
});

This works for me especially in pivots table filtering when I want the count of cells with data on a filtered column. Reduce k accordingly (k - 1) if you have a header row for filtering:

k = Sheets("Sheet1").Range("$A:$A").SpecialCells(xlCellTypeVisible).SpecialCells(xlCellTypeConstants).Count

List<? extends HasWord> accepts any concrete classes that extends HasWord. If you have the following classes...

public class A extends HasWord { .. }
public class B extends HasWord { .. }
public class C { .. }
public class D extends SomeOtherWord { .. }

... the wordList can ONLY contain a list of either As or Bs or mixture of both because both classes extend the same parent or null (which fails instanceof checks for HasWorld).

Well Facebook has undergone MANY many changes and it wasn't originally designed to be efficient. It was designed to do it's job. I have absolutely no idea what the code looks like and you probably won't find much info about it (for obvious security and copyright reasons), but just take a look at the API. Look at how often it changes and how much of it doesn't work properly, anymore, or at all.

I think the biggest ace up their sleeve is the Hiphop. http://developers.facebook.com/blog/post/358 You can use HipHop yourself: https://github.com/facebook/hiphop-php/wiki

But if you ask me it's a very ambitious and probably time wasting task. Hiphop only supports so much, it can't simply convert everything to C++. So what does this tell us? Well, it tells us that Facebook is NOT fully taking advantage of the PHP language. It's not using the latest 5.3 and I'm willing to bet there's still a lot that is PHP 4 compatible. Otherwise, they couldn't use HipHop. HipHop IS A GOOD IDEA and needs to grow and expand, but in it's current state it's not really useful for that many people who are building NEW PHP apps.

There's also PHP to JAVA via things like Resin/Quercus. Again, it doesn't support everything...

Another thing to note is that if you use any non-standard PHP module, you aren't going to be able to convert that code to C++ or Java either. However...Let's take a look at PHP modules. They are ARE compiled in C++. So if you can build PHP modules that do things (like parse XML, etc.) then you are basically (minus some interaction) working at the same speed. Of course you can't just make a PHP module for every possible need and your entire app because you would have to recompile and it would be much more difficult to code, etc.

However...There are some handy PHP modules that can help with speed concerns. Though at the end of the day, we have this awesome thing known as "the cloud" and with it, we can scale our applications (PHP included) so it doesn't matter as much anymore. Hardware is becoming cheaper and cheaper. Amazon just lowered it's prices (again) speaking of.

So as long as you code your PHP app around the idea that it will need to one day scale...Then I think you're fine and I'm not really sure I'd even look at Facebook and what they did because when they did it, it was a completely different world and now trying to hold up that infrastructure and maintain it...Well, you get things like HipHop.

Now how is HipHop going to help you? It won't. It can't. You're starting fresh, you can use PHP 5.3. I'd highly recommend looking into PHP 5.3 frameworks and all the new benefits that PHP 5.3 brings to the table along with the SPL libraries and also think about your database too. You're most likely serving up content from a database, so check out MongoDB and other types of databases that are schema-less and document-oriented. They are much much faster and better for the most "common" type of web site/app.

Look at NEW companies like Foursquare and Smugmug and some other companies that are utilizing NEW technology and HOW they are using it. For as successful as Facebook is, I honestly would not look at them for "how" to build an efficient web site/app. I'm not saying they don't have very (very) talented people that work there that are solving (their) problems creatively...I'm also not saying that Facebook isn't a great idea in general and that it's not successful and that you shouldn't get ideas from it....I'm just saying that if you could view their entire source code, you probably wouldn't benefit from it.

Basically any file that is automatically regenerated.

A good test is to clone your repo and see if Android Studio is able to interpret and run your project immediately (generating what is missing).
If not, find what is missing, and make sure it isn't ignored, but added to the repo.

That being said, you can take example on existing .gitignore files, like the Android one.

# built application files
*.apk
*.ap_

# files for the dex VM
*.dex

# Java class files
*.class

# generated files
bin/
gen/

# Local configuration file (sdk path, etc)
local.properties

# Eclipse project files
.classpath
.project

# Proguard folder generated by Eclipse
proguard/

# Intellij project files
*.iml
*.ipr
*.iws
.idea/

Notes:

• xiaobai's answer is simpler (git1.7.6+): git status --ignored
  (as detailed in "Is there a way to tell git-status to ignore the effects of .gitignore files?")
• MattDiPasquale's answer (to be upvoted) git clean -ndX works on older gits, displaying a preview of what ignored files could be removed (without removing anything)

Also interesting (mentioned in qwertymk's answer), you can also use the git check-ignore -v command, at least on Unix (doesn't work in a CMD Windows session)

git check-ignore *
git check-ignore -v *

The second one displays the actual rule of the .gitignore which makes a file to be ignored in your git repo.
On Unix, using "What expands to all files in current directory recursively?" and a bash4+:

git check-ignore **/*

(or a find -exec command)

Note: https://stackoverflow.com/users/351947/Rafi B. suggests in the comments to avoid the (risky) globstar:

git check-ignore -v $(find . -type f -print)

Make sure to exclude the files from the .git/ subfolder though.

Original answer 42009)

git ls-files -i

should work, except its source code indicates:

if (show_ignored && !exc_given) {
                fprintf(stderr, "%s: --ignored needs some exclude pattern\n",
                        argv[0]);

exc_given ?

It turns out it need one more parameter after the -i to actually list anything:

Try:

git ls-files -i --exclude-from=[Path_To_Your_Global].gitignore

(but that would only list your cached (non-ignored) object, with a filter, so that is not quite what you want)

Example:

$ cat .git/ignore
# ignore objects and archives, anywhere in the tree.
*.[oa]
$ cat Documentation/.gitignore
# ignore generated html files,
*.html
# except foo.html which is maintained by hand
!foo.html
$ git ls-files --ignored \
    --exclude='Documentation/*.[0-9]' \
    --exclude-from=.git/ignore \
    --exclude-per-directory=.gitignore

Actually, in my 'gitignore' file (called 'exclude'), I find a command line that could help you:

F:\prog\git\test\.git\info>type exclude
# git ls-files --others --exclude-from=.git/info/exclude
# Lines that start with '#' are comments.
# For a project mostly in C, the following would be a good set of
# exclude patterns (uncomment them if you want to use them):
# *.[oa]
# *~

So....

git ls-files --ignored --exclude-from=.git/info/exclude
git ls-files -i --exclude-from=.git/info/exclude

git ls-files --others --ignored --exclude-standard
git ls-files -o -i --exclude-standard

should do the trick.

(Thanks to honzajde pointing out in the comments that git ls-files -o -i --exclude-from... does not include cached files: only git ls-files -i --exclude-from... (without -o) does.)

As mentioned in the ls-files man page, --others is the important part, in order to show you non-cached, non-committed, normally-ignored files.

--exclude_standard is not just a shortcut, but a way to include all standard "ignored patterns" settings.

exclude-standard
Add the standard git exclusions: .git/info/exclude, .gitignore in each directory, and the user's global exclusion file.

The res.json() function should be sufficient for most cases.

app.get('/', (req, res) => res.json({ answer: 42 }));

The res.json() function converts the parameter you pass to JSON using JSON.stringify() and sets the Content-Type header to application/json; charset=utf-8 so HTTP clients know to automatically parse the response.

For starters:

<p align='center'>
<table width='100%'>
<tr>
<td align='center'><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

Note, if the width of the input button is 100%, you wont need the attribute "align='center'" anymore.

This would be the optimal solution:

<p align='center'>
<table width='100%'>
<tr>
<td><form><input type=submit value="click me" style="width:100%"></form></td>
</tr>
</table>
</p>

In the newer versions of GWT (starting either 2.3 or 2.4, i believe), you can also add

<collapse-all-properties />

to your gwt.xml for development purposes. That will tell the GWT compiler to create a single permutation which covers all locales and browsers. Therefore, you can still test in all browsers and languages, but are still only compiling a single permutation

Nothing stops you from doing the above, but hold up!

There are some gotchas. Assignment in Javascript is from right to left so when you write:

var moveUp = moveDown = moveLeft = moveRight = mouseDown = touchDown = false;

it effectively translates to:

var moveUp = (moveDown = (moveLeft = (moveRight = (mouseDown = (touchDown = false)))));

which effectively translates to:

var moveUp = (window.moveDown = (window.moveLeft = (window.moveRight = (window.mouseDown = (window.touchDown = false)))));

Inadvertently, you just created 5 global variables--something I'm pretty sure you didn't want to do.

Note: My above example assumes you are running your code in the browser, hence window. If you were to be in a different environment these variables would attach to whatever the global context happens to be for that environment (i.e., in Node.js, it would attach to global which is the global context for that environment).

Now you could first declare all your variables and then assign them to the same value and you could avoid the problem.

var moveUp, moveDown, moveLeft, moveRight, mouseDown, touchDown;
moveUp = moveDown = moveLeft = moveRight = mouseDown = touchDown = false;

Long story short, both ways would work just fine, but the first way could potentially introduce some pernicious bugs in your code. Don't commit the sin of littering the global namespace with local variables if not absolutely necessary.

Sidenote: As pointed out in the comments (and this is not just in the case of this question), if the copied value in question was not a primitive value but instead an object, you better know about copy by value vs copy by reference. Whenever assigning objects, the reference to the object is copied instead of the actual object. All variables will still point to the same object so any change in one variable will be reflected in the other variables and will cause you a major headache if your intention was to copy the object values and not the reference.

You can use line-height: 50px;, you won't need vertical-align: middle; there.

Demo

The above will fail if you've multiple lines, so in that case you can wrap your text using span and than use display: table-cell; and display: table; along with vertical-align: middle;, also don't forget to use width: 100%; for #abc

Demo

#abc{
  font:Verdana, Geneva, sans-serif;
  font-size:18px;
  text-align:left;
  background-color:#0F0;
  height:50px;
  display: table;
  width: 100%;
}

#abc span {
  vertical-align:middle;
  display: table-cell;
}

Another solution I can think of here is to use transform property with translateY() where Y obviously stands for Y Axis. It's pretty straight forward... All you need to do is set the elements position to absolute and later position 50% from the top and translate from it's axis with negative -50%

div {
  height: 100px;
  width: 100px;
  background-color: tomato;
  position: relative;
}

p {
  position: absolute;
  top: 50%;
  transform: translateY(-50%);
}

Demo

Note that this won't be supported on older browsers, for example IE8, but you can make IE9 and other older browser versions of Chrome and Firefox by using -ms, -moz and -webkit prefixes respectively.

For more information on transform, you can refer here.

In theory, yes, as long as you don't exceed the maximum url and/oor query string length for the client or server.

In practice, things can get a bit trickier. For example, it can trigger an HttpRequestValidationException on ASP.NET if the value happens to contain an "on" and you leave in the trailing "==".

htdocs is your default document-root directory, so you have to use localhost/index.html to see that html file. In other words, localhost is mapped to xampp/htdocs, so index.html is at localhost itself. You can change the location of document root by modifying httpd.conf and restarting the server.

It's swift format :

func dateFormatterWithCalendar(calndarIdentifier: Calendar.Identifier, dateFormat: String) -> DateFormatter {

    let formatter = DateFormatter()
    formatter.calendar = Calendar(identifier: calndarIdentifier)
    formatter.dateFormat = dateFormat

    return formatter

//Usage
let date = Date()
let fotmatter = dateFormatterWithCalendar(calndarIdentifier: .gregorian, dateFormat: "yyyy")
let dateString = fotmatter.string(from: date)
print(dateString) //2018

Also look at log4net, which makes logging to 1 or more event stores — whether it's the console, the Windows event log, a text file, a network pipe, a SQL database, etc. — pretty trivial. You can even filter stuff in its configuration, for instance, so that only log records of a particular severity (say ERROR or FATAL) from a single component or assembly are directed to a particular event store.

As Charles Duffey has stated, XML parsers are best parsed with a proper XML parsing tools. For one time job the following should work.

grep -oPm1 "(?<=<title>)[^<]+"

Test:

$ echo "$data"
<item> 
  <title>15:54:57 - George:</title>
  <description>Diane DeConn? You saw Diane DeConn!</description> 
</item> 
<item> 
  <title>15:55:17 - Jerry:</title> 
  <description>Something huh?</description>
$ title=$(grep -oPm1 "(?<=<title>)[^<]+" <<< "$data")
$ echo "$title"
15:54:57 - George:

the solution for this can be as easy as :

1. find the phpmysqladmin connection function/method
2. add this after database is conncted $db_conect->set_charset('utf8');

lencioni's answer is what I'd recommend. You can change the selector for the option ('#mySelect option:last') to select the option with a specific value using "#mySelect option[value='yourDefaultValue']". More on selectors.

If you're working extensively with select lists on the client check out this plugin: http://www.texotela.co.uk/code/jquery/select/. Take a look the source if you want to see some more examples of working with select lists.

I such cases I usually end up with a list of predicates and actions. Something along these lines:

class Mine {
    static List<Func<object, bool>> predicates;
    static List<Action<object>> actions;

    static Mine() {
        AddAction<A>(o => o.Hop());
        AddAction<B>(o => o.Skip());
    }

    static void AddAction<T>(Action<T> action) {
        predicates.Add(o => o is T);
        actions.Add(o => action((T)o);
    }

    static void RunAction(object o) {
        for (int i=0; o < predicates.Count; i++) {
            if (predicates[i](o)) {
                actions[i](o);
                break;
            }
        }
    }

    void Foo(object o) {
        RunAction(o);
    }
}

Wrap your to be deleted contents within a ptag, then you can do something like this:

    $("td").find("p").remove();    });
});

It depends on the concrete situation.. but in general:

PUT = update or change a concrete resource with a concrete URI of the resource.

POST = create a new resource under the source of the given URI.

I.e.

Edit a blog post:

PUT: /blog/entry/1

Create a new one:

POST: /blog/entry

PUT may create a new resource in some circumstances where the URI of the new ressource is clear before the request. POST can be used to implement several other use cases, too, which are not covered by the others (GET, PUT, DELETE, HEAD, OPTIONS)

The general understanding for CRUD systems is GET = request, POST = create, Put = update, DELETE = delete

Consider using the function shapiro.test, which performs the Shapiro-Wilks test for normality. I've been happy with it.

Quick and easy way:

1- open MainActivity.java or any available java file.

At the top there is the package declaration such as:

package com.example.myapp;

select the package portion that you want to change and press Shift+F6. I personally want to change the example.

In the warning dialog, select Rename package and then insert the desired package name.

2- Open AndroidManifest.xml and inside <manifest> tag change the package to the desired package name.

3- open build.gradle(Module: app) and change the applicationId to the desired package name.

What is the exact contents you are passing into $html_brand?

WebSocket is just another application level protocol over TCP protocol, just like HTTP.

Some snippets < Spring in Action 4> quoted below, hope it can help you understand WebSocket better.

In its simplest form, a WebSocket is just a communication channel between two applications (not necessarily a browser is involved)...WebSocket communication can be used between any kinds of applications, but the most common use of WebSocket is to facilitate communication between a server application and a browser-based application.

Beware of recipes like this

target:
    MY_ID=$(GENERATE_ID);
    echo $MY_ID;

It does two things wrong. The first line in the recipe is executed in a separate shell instance from the second line. The variable is lost in the meantime. Second thing wrong is that the $ is not escaped.

target:
    MY_ID=$(GENERATE_ID); \
    echo $$MY_ID;

Both problems have been fixed and the variable is useable. The backslash combines both lines to run in one single shell, hence the setting of the variable and the reading of the variable afterwords, works.

I realize the original post said how to get the results of a shell command into a MAKE variable, and this answer shows how to get it into a shell variable. But other readers may benefit.

One final improvement, if the consumer expects an "environment variable" to be set, then you have to export it.

my_shell_script
    echo $MY_ID

would need this in the makefile

target:
    export MY_ID=$(GENERATE_ID); \
    ./my_shell_script;

Hope that helps someone. In general, one should avoid doing any real work outside of recipes, because if someone use the makefile with '--dry-run' option, to only SEE what it will do, it won't have any undesirable side effects. Every $(shell) call is evaluated at compile time and some real work could accidentally be done. Better to leave the real work, like generating ids, to the inside of the recipes when possible.

note that explode has a limit function. So you could do something like

$message = implode(" ", explode(" ", $long_message, 20));

The key term is modal-dialog.

As such there is no built in modal-dialog offered.

But you can use many others available e.g. this

There is a Java project - Dead Code Detector (DCD). For source code it doesn't seem to work well, but for .jar file - it's really good. Plus you can filter by class and by method.

XCODE 10.1

1. Goto Xcode -> Preferences (Shortcut CMD,)

2. Select Components

3. Download Simulator version

4. XCode -> Open Developer Tool -> Simulator This will launch Simulator as stand alone application

5 Hardware -> Device -> Manage Devices...

6. Click on + iCon to create new simulator version.

7. Specify Simulator Name, Device Type and Choose OS version from drop down.

8. Click Create.

9. Hardware -> Device -> iOS 11.0 -> iPhone 6

Thats it run enjoy coding!

Yup, as everyone's saying, line-height is the thing. Any font you are using, a mid-height character (such as a or ¦, not going through the upper or lower) should go with the same height-length at line-height: 0.6 to 0.65.

Mark, this is already answered in your previous topic. But OK, here it is again:

Suppose ${list} points to a List<Object>, then the following

<c:forEach items="${list}" var="item">
    ${item}<br>
</c:forEach>

does basically the same as as following in "normal Java":

for (Object item : list) {
    System.out.println(item);
}

If you have a List<Map<K, V>> instead, then the following

<c:forEach items="${list}" var="map">
    <c:forEach items="${map}" var="entry">
        ${entry.key}<br>
        ${entry.value}<br>
    </c:forEach>
</c:forEach>

does basically the same as as following in "normal Java":

for (Map<K, V> map : list) {
    for (Entry<K, V> entry : map.entrySet()) {
        System.out.println(entry.getKey());
        System.out.println(entry.getValue());
    }
}

The key and value are here not special methods or so. They are actually getter methods of Map.Entry object (click at the blue Map.Entry link to see the API doc). In EL (Expression Language) you can use the . dot operator to access getter methods using "property name" (the getter method name without the get prefix), all just according the Javabean specification.

That said, you really need to cleanup the "answers" in your previous topic as they adds noise to the question. Also read the comments I posted in your "answers".

I would recomment Pluralsight's tool for creating self-signed-certs: http://blog.pluralsight.com/selfcert-create-a-self-signed-certificate-interactively-gui-or-programmatically-in-net

Make your cert as a .pfx and import it into IIS. And add it as a trusted root cert authority.

The fallthrough answers by others are good ones.

However another approach would be extract methods out of the contents of your case statements and then just call the appropriate method from each case.

In the example below, both case 'text1' and case 'text4' behave the same:

switch (name) {
        case text1: {
            method1();
            break;
        }
        case text2: {
            method2();
            break;
        }
        case text3: {
            method3();
            break;
        }
        case text4: {
            method1();
            break;
        }

I personally find this style of writing case statements more maintainable and slightly more readable, especially when the methods you call have good descriptive names.

Specific to XCode 9.1:
You can refere to @Krunal's answer above or follow below steps

its bit tricky to adjust Simulator size.

If you want to zoom your simulator screen follow below steps :

• Goto Window->Uncheck Show Device Bezels

• Goto Window->select zoom

after doing this you can resize your simulator by dragging edges of simulator.

Pixel Accurate : Its to display your simulator in same size as Physical device pixels, if your screen size doesn't have enough resolution to cover dimension it would not enable Pixel Accurate option.

Alternate is change simulator to landscape mode by clicking ? + ? ,then you could click ? + 2 to select Pixel Accurate option (make sure you have disable Show Device Bezels to reduce size.

Inspired by VB.Net Generics List(Of Integer), I created my own module for that. Maybe you find it useful, too or you'd like to extend for additional methods e.g. to remove items again:

'Save module with name: ListOfInteger

Public Function ListLength(list() As Integer) As Integer
On Error Resume Next
ListLength = UBound(list) + 1
On Error GoTo 0
End Function

Public Sub ListAdd(list() As Integer, newValue As Integer)
ReDim Preserve list(ListLength(list))
list(UBound(list)) = newValue
End Sub

Public Function ListContains(list() As Integer, value As Integer) As Boolean
ListContains = False
Dim MyCounter As Integer
For MyCounter = 0 To ListLength(list) - 1
    If list(MyCounter) = value Then
        ListContains = True
        Exit For
    End If
Next
End Function

Public Sub DebugOutputList(list() As Integer)
Dim MyCounter As Integer
For MyCounter = 0 To ListLength(list) - 1
    Debug.Print list(MyCounter)
Next
End Sub

You might use it as follows in your code:

Public Sub IntegerListDemo_RowsOfAllSelectedCells()
Dim rows() As Integer

Set SelectedCellRange = Excel.Selection
For Each MyCell In SelectedCellRange
    If IsEmpty(MyCell.value) = False Then
        If ListOfInteger.ListContains(rows, MyCell.Row) = False Then
            ListAdd rows, MyCell.Row
        End If
    End If
Next
ListOfInteger.DebugOutputList rows

End Sub

If you need another list type, just copy the module, save it at e.g. ListOfLong and replace all types Integer by Long. That's it :-)

I think this is the easiest way to loop in react js

<ul>
    {yourarray.map((item)=><li>{item}</li>)}
</ul>

try this

document.getElementById("datapicker").addEventListener("submit", function())

Epsilon is your "fuzz factor," since doubles may not be exactly equal. Epsilon lets you describe how close they have to be.

If you were expecting 3.14159 but would take anywhere from 3.14059 to 3.14259 (that is, within 0.001), then you should write something like

double myPi = 22.0d / 7.0d; //Don't use this in real life!
assertEquals(3.14159, myPi, 0.001);

(By the way, 22/7 comes out to 3.1428+, and would fail the assertion. This is a good thing.)

You can't just change the delimiters from ---- BEGIN SSH2 PUBLIC KEY ---- to -----BEGIN RSA PUBLIC KEY----- and expect that it will be sufficient to convert from one format to another (which is what you've done in your example).

This article has a good explanation about both formats.

What you get in an RSA PUBLIC KEY is closer to the content of a PUBLIC KEY, but you need to offset the start of your ASN.1 structure to reflect the fact that PUBLIC KEY also has an indicator saying which type of key it is (see RFC 3447). You can see this using openssl asn1parse and -strparse 19, as described in this answer.

EDIT: Following your edit, your can get the details of your RSA PUBLIC KEY structure using grep -v -- ----- | tr -d '\n' | base64 -d | openssl asn1parse -inform DER:

    0:d=0  hl=4 l= 266 cons: SEQUENCE          
    4:d=1  hl=4 l= 257 prim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
  265:d=1  hl=2 l=   3 prim: INTEGER           :010001

To decode the SSH key format, you need to use the data format specification in RFC 4251 too, in conjunction with RFC 4253:

   The "ssh-rsa" key format has the following specific encoding:

      string    "ssh-rsa"
      mpint     e
      mpint     n

For example, at the beginning, you get 00 00 00 07 73 73 68 2d 72 73 61. The first four bytes (00 00 00 07) give you the length. The rest is the string itself: 73=s, 68=h, ... -> 73 73 68 2d 72 73 61=ssh-rsa, followed by the exponent of length 1 (00 00 00 01 25) and the modulus of length 256 (00 00 01 00 7f ...).

From wikipedia:

In computer science, an array data structure or simply array is a data structure consisting of a collection of elements (values or variables), each identified by one or more integer indices, stored so that the address of each element can be computed from its index tuple by a simple mathematical formula.

So when you say byte array, you're referring to an array of some defined length (e.g. number of elements) that contains a collection of byte (8 bits) sized elements.

In C# a byte array could look like:

byte[] bytes = { 3, 10, 8, 25 };

The sample above defines an array of 4 elements, where each element can be up to a Byte in length.

A simpler approach is to capture the Back button press and call moveTaskToBack(true) as follows:

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_BACK) {
        moveTaskToBack(true);
        return true;
    }
    return super.onKeyDown(keyCode, event);
}

Android 2.0 introduced a new onBackPressed method, and these recommendations on how to handle the Back button

You'll need to use os.stat to get the file creation time and a combination of time.strftime and time.timezone for formatting:

>>> import time
>>> import os
>>> t = os.stat('C:/Path/To/File.txt').st_ctime
>>> t = time.localtime(t)
>>> formatted = time.strftime('%Y-%m-%d %H:%M:%S', t)
>>> tz = str.format('{0:+06.2f}', float(time.timezone) / 3600)
>>> final = formatted + tz
>>> 
>>> final
'2008-11-24 14:46:08-02.00'

Developer Tools > Elements > Computed > Rendered Fonts

The picture you attached to your question shows the Style tab. If you change to the next tab, Computed, you can check the Rendered Fonts, that shows the actual font-family rendered.

you can also use the following:

s.concat("world")

You can null/blank/space Etc value using LinQ Use Following Query

   var BlankValueRows = (from dr1 in Dt.AsEnumerable()
                                  where dr1["Columnname"].ToString() == ""
                                  || dr1["Columnname"].ToString() == ""
                                   || dr1["Columnname"].ToString() == ""
                                  select Columnname);

Here Replace Columnname with table column name and "" your search item in above code we looking null value.

Pretty easy to do this across multiple cells, without having to add '%' to each individually.

Select all the cells you want to change to percent, right Click, then format Cells, choose Custom. Type in 0.0\%.

There's obviously more than one way to do it, but I would suggest using the more standard:

ErrorDocument 404 /index.php?page=404

Swift 3:

protocol

@objc protocol SomeDelegate {
    @objc optional func method()
}

Object

class SomeObject : NSObject {

weak var delegate:SomeObject?

func delegateMethod() {

     if let delegateMethod = delegate?.method{
         delegateMethod()
     }else {
        //Failed
     }

   }

}

Short answer:

x.addEventListener("click", function(e){myfunction(e, param1, param2)});

... 

function myfunction(e, param1, param1) {
    ... 
} 

Thanks to Alex Mckay I had a resolve for dynamic setting a props:

  for(let prop in filter)
      (state.filter as Record<string, any>)[prop] = filter[prop];

The catch is that input elements are inline. We have to make it block (display:block) before positioning it to center : margin : 0 auto. Please see the code below :

<html>
<head>
    <style>
        div.wrapper {
            width: 300px;
            height:300px;
            border:1px solid black;
        }

        input[type="text"] {
             display: block;
             margin : 0 auto;
        }

    </style>
</head>
<body>

    <div class='wrapper'>
        <input type='text' name='ok' value='ok'>
    </div>    


</body>
</html>

But if you have a div which is positioned = absolute then we need to do the things little bit differently.Now see this!

  <html>
     <head>
    <style>
        div.wrapper {
            position:  absolute;
            top : 200px;
            left: 300px;
            width: 300px;
            height:300px;
            border:1px solid black;
        }

        input[type="text"] {
             position: relative;
             display: block;
             margin : 0 auto;
        }

    </style>
</head>
<body>

    <div class='wrapper'>
        <input type='text' name='ok' value='ok'>
    </div>  

</body>
</html>

Hoping this can be helpful.Thank you.

Sure, you can (I am leaving your T-business aside):

public IEnumerable<string> tryAdd(IEnumerable<string> items)
{
    List<string> list = items.ToList();
    string obj = "";
    list.Add(obj);

    return list.Select(i => i);
}

There is no such thing as associative array in Java. Its closest relative is a Map, which is strongly typed, however has less elegant syntax/API.

This is the closest you can get based on your example:

Map<Integer, Map<String, String>> arr = 
    org.apache.commons.collections.map.LazyMap.decorate(
         new HashMap(), new InstantiateFactory(HashMap.class));

//$arr[0]['name'] = 'demo';
arr.get(0).put("name", "demo");

System.out.println(arr.get(0).get("name"));
System.out.println(arr.get(1).get("name"));    //yields null

If you are in taxonomy page.

That's how you get all details about the taxonomy.

get_term_by( 'slug', get_query_var( 'term' ), get_query_var( 'taxonomy' ) );

This is how you get the taxonomy id

$termId = get_term_by( 'slug', get_query_var( 'term' ), get_query_var( 'taxonomy' ) )->term_id;

But if you are in post page (taxomony -> child)

$terms = wp_get_object_terms( get_queried_object_id(), 'taxonomy-name');
$term_id = $terms[0]->term_id;

If you want to append to the file, open it with 'a'. If you want to seek through the file to find the place where you should insert the line, use 'r+'. (docs)

You can use WebBrowser control to render in memory your html content. After LoadCompleted event fired...

IHTMLDocument2 htmlDoc = (IHTMLDocument2)webBrowser.Document;
string innerHTML = htmlDoc.body.innerHTML;
string innerText = htmlDoc.body.innerText;

Instead of the bulky DateTime object .. just use the core date() function

function isValidDate($date, $format= 'Y-m-d'){
    return $date == date($format, strtotime($date));
}

public void keyReleased(KeyEvent e)
{
    int key=e.getKeyCode();
    if(e.getSource()==textField)
    {
        if(key==KeyEvent.VK_ENTER)
        { 
            Toolkit.getDefaultToolkit().beep();
            textField_1.requestFocusInWindow();                     
        }
    }

To write logic for 'Enter press' in JTextField, it is better to keep logic inside the keyReleased() block instead of keyTyped() & keyPressed().

If you are looking to just repopulate the fields with the values that were posted in them, then just echo the post value back into the field, like so:

<input type="text" name="myField1" value="<?php echo isset($_POST['myField1']) ? $_POST['myField1'] : '' ?>" />

I have something like the following

function initMap()
{
    //...create new map here
    var infowindow;
    $('.business').each(function(el){
        //...get lat/lng
        var position = new google.maps.LatLng(lat, lng);
        var content = "contents go here";
        var title = "titleText";
        var openWindowFn;
        var closure = function(content, position){.
            openWindowFn = function()
            {
                if (infowindow)
                {
                    infowindow.close();
                }
                infowindow = new google.maps.InfoWindow({
                    position:position,
                    content:content
                });
                infowindow.open(map, marker);
            }
        }(content, position);
        var marker = new google.maps.Marker({
            position:position,
            map:map,
            title:title.
        });
        google.maps.event.addListener(marker, 'click', openWindowFn);
    }
}

In my understanding, using a closure like that allows the capturing of variables and their values at the time of function declaration, rather than relying on global variables. So when openWindowFn is called later, on the first marker for example, the content and position variable have the values they did during the first iteration in the each() function.

I'm not really sure how openWindowFn has infowindow in its scope. I'm also not sure I'm doing things right, but it works, even with multiple maps on one page (each map gets one open infowindow).

If anyone has any insights, please comment.

The mipmap folders are for placing your app/launcher icons (which are shown on the homescreen) in only. Any other drawable assets you use should be placed in the relevant drawable folders as before.

According to this Google blogpost:

It’s best practice to place your app icons in mipmap- folders (not the drawable- folders) because they are used at resolutions different from the device’s current density.

When referencing the mipmap- folders ensure you are using the following reference:

android:icon="@mipmap/ic_launcher"

The reason they use a different density is that some launchers actually display the icons larger than they were intended. Because of this, they use the next size up.

Simply replacing .bin with .tar.bz2 is not enough, for NDK releases older than 10b. For example, https://dl.google.com/android/ndk/android-ndk-r10b-linux-x86_64.tar.bz2 is not a valid link.

Turned out that the correct link for 10b was: https://dl.google.com/android/ndk/android-ndk32-r10b-linux-x86_64.tar.bz2 (note the additional '32'). However, this doesn't seem to apply to e.g. 10a, as this link doesn't work: https://dl.google.com/android/ndk/android-ndk32-r10a-linux-x86_64.tar.bz2 .

Bottom line: use http://web.archive.org until Google fixes this, if ever...

if you need to include the key of the document in the response, another alternative is:

async getMarker() {
    const snapshot = await firebase.firestore().collection('events').get()
    const documents = [];
    snapshot.forEach(doc => {
       documents[doc.id] = doc.data();
    });
    return documents;
}

If you want to round it to lower, just cast it.

float my_float = 42.8f;
int my_int;
my_int = (int)my_float;          // => my_int=42

For other purpose, if you want to round it to nearest, you can make a little function or a define like this:

#define FLOAT_TO_INT(x) ((x)>=0?(int)((x)+0.5):(int)((x)-0.5))

float my_float = 42.8f;
int my_int;
my_int = FLOAT_TO_INT(my_float); // => my_int=43

Be careful, ideally you should verify float is between INT_MIN and INT_MAX before casting it.

Follow these steps to project to Github

1) git init

2) git add .

3) git commit -m "Add all my files"

4) git remote add origin https://github.com/yourusername/your-repo-name.git

Upload of project from scratch require git pull origin master.

5) git pull origin master

6) git push origin master

The console.log should be wrapped in a function , the "default" function for every class is its constructor so it should be declared there.

import { Component } from '@angular/core';
console.log("Hello1");

 @Component({
  selector: 'hello-console',
})
    export class App {
     s: string = "Hello2";
    constructor(){
     console.log(s); 
    }

}

It's not directly possible.

However, this can be done using CustomEvent: https://developer.mozilla.org/en-US/docs/Web/API/CustomEvent/CustomEvent

The below method accepts an array of variable names as an input and adds event listener for each variable and triggers the event for any changes to the value of the variables.

The Method uses polling to detect the change in the value. You can increase the value for timeout in milliseconds.

function watchVariable(varsToWatch) {
    let timeout = 1000;
    let localCopyForVars = {};
    let pollForChange = function () {
        for (let varToWatch of varsToWatch) {
            if (localCopyForVars[varToWatch] !== window[varToWatch]) {
                let event = new CustomEvent('onVar_' + varToWatch + 'Change', {
                    detail: {
                        name: varToWatch,
                        oldValue: localCopyForVars[varToWatch],
                        newValue: window[varToWatch]
                    }
                });
                document.dispatchEvent(event);
                localCopyForVars[varToWatch] = window[varToWatch];
            }
        }
        setTimeout(pollForChange, timeout);
    };
    let respondToNewValue = function (varData) {
        console.log("The value of the variable " + varData.name + " has been Changed from " + varData.oldValue + " to " + varData.newValue + "!!!"); 
    }
    for (let varToWatch of varsToWatch) {
        localCopyForVars[varToWatch] = window[varToWatch];
        document.addEventListener('onVar_' + varToWatch + 'Change', function (e) {
            respondToNewValue(e.detail);
        });
    }
    setTimeout(pollForChange, timeout);
}

By calling the Method:

watchVariables(['username', 'userid']);

It will detect the changes to variables username and userid.

Actually, the best practice is to store your database crendentials in environment variables because :

• These credentials are dependant to environment, it means that you won't have the same credentials in dev/prod. Storing them in the same file for all environment is a mistake.
• Credentials are not related to business logic which means login and password have nothing to do in your code.
• You can set environment variables without creating any business code class file, which means you will never make the mistake of adding the credential files to a commit in Git.
• Environments variables are superglobales : you can use them everywhere in your code without including any file.

How to use them ?

• Using the $_ENV array :
  • Setting : $_ENV['MYVAR'] = $myvar
  • Getting : echo $_ENV["MYVAR"]
• Using the php functions :
  • Setting with the putenv function - putenv("MYVAR=$myvar");
  • Getting with the getenv function - getenv('MYVAR');
• In vhosts files and .htaccess but it's not recommended since its in another file and its not resolving the problem by doing it this way.

You can easily drop a file such as envvars.php with all environment variables inside and execute it (php envvars.php) and delete it. It's a bit old school, but it still work and you don't have any file with your credentials in the server, and no credentials in your code. Since it's a bit laborious, frameworks do it better.

Example with Symfony (ok its not only PHP) The modern frameworks such as Symfony recommends using environment variables, and store them in a .env not commited file or directly in command lines which means you wether can do :

• With CLI : symfony var:set FOO=bar --env-level
• With .env or .env.local : FOO="bar"

Supernova answer for django/boto3/django-storages worked with me:

AWS_S3_REGION_NAME = "ap-south-1"

Or previous to boto3 version 1.4.4:

AWS_S3_REGION_NAME = "ap-south-1"

AWS_S3_SIGNATURE_VERSION = "s3v4"

just add them to your settings.py and change region code accordingly

you can check aws regions from: enter link description here

const router = new VueRouter({
  mode: 'history',
  routes: [...]
})

And if you are using AWS amplify, check this article on how to configure server: Vue router’s history mode and AWS Amplify

Combine two answers above, I finally make it work. Just be careful that the first single quote for each string is a backtick (`) in file sendmail.mc.

#Change to your mail config directory:
cd /etc/mail

#Make a auth subdirectory
mkdir auth
chmod 700 auth  #maybe not, because I cannot apply cmd "cd auth" if I do so.

#Create a file with your auth information to the smtp server
cd auth
touch client-info

#In the file, put the following, matching up to your smtp server:
AuthInfo:your.isp.net "U:root" "I:user" "P:password"

#Generate the Authentication database, make both files readable only by root
makemap hash client-info < client-info
chmod 600 client-info
cd ..

#Add the following lines to sendmail.mc. Make sure you update your smtp server
#The first single quote for each string should be changed to a backtick (`) like this:
define(`SMART_HOST',`your.isp.net')dnl
define(`confAUTH_MECHANISMS', `EXTERNAL GSSAPI DIGEST-MD5 CRAM-MD5 LOGIN PLAIN')dnl
FEATURE(`authinfo',`hash /etc/mail/auth/client-info')dnl

#run 
sudo sendmailconfig

Have no fear, because a brave group of Ops Programmers have solved the situation with a brand spanking new nginx_tcp_proxy_module

Written in August 2012, so if you are from the future you should do your homework.

Prerequisites

Assumes you are using CentOS:

• Remove current instance of NGINX (suggest using dev server for this)
• If possible, save your old NGINX config files so you can re-use them (that includes your init.d/nginx script)
• yum install pcre pcre-devel openssl openssl-devel and any other necessary libs for building NGINX
• Get the nginx_tcp_proxy_module from GitHub here https://github.com/yaoweibin/nginx_tcp_proxy_module and remember the folder where you placed it (make sure it is not zipped)

Build Your New NGINX

Again, assumes CentOS:

• cd /usr/local/
• wget 'http://nginx.org/download/nginx-1.2.1.tar.gz'
• tar -xzvf nginx-1.2.1.tar.gz
• cd nginx-1.2.1/
• patch -p1 < /path/to/nginx_tcp_proxy_module/tcp.patch
• ./configure --add-module=/path/to/nginx_tcp_proxy_module --with-http_ssl_module (you can add more modules if you need them)
• make
• make install

Optional:

• sudo /sbin/chkconfig nginx on

Set Up Nginx

Remember to copy over your old configuration files first if you want to re-use them.

Important: you will need to create a tcp {} directive at the highest level in your conf. Make sure it is not inside your http {} directive.

The example config below shows a single upstream websocket server, and two proxies for both SSL and Non-SSL.

tcp {
    upstream websockets {
        ## webbit websocket server in background
        server 127.0.0.1:5501;
        
        ## server 127.0.0.1:5502; ## add another server if you like!

        check interval=3000 rise=2 fall=5 timeout=1000;
    }   

    server {
        server_name _;
        listen 7070;

        timeout 43200000;
        websocket_connect_timeout 43200000;
        proxy_connect_timeout 43200000;

        so_keepalive on;
        tcp_nodelay on;

        websocket_pass websockets;
        websocket_buffer 1k;
    }

    server {
        server_name _;
        listen 7080;

        ssl on;
        ssl_certificate      /path/to/cert.pem;
        ssl_certificate_key  /path/to/key.key;

        timeout 43200000;
        websocket_connect_timeout 43200000;
        proxy_connect_timeout 43200000;

        so_keepalive on;
        tcp_nodelay on;

        websocket_pass websockets;
        websocket_buffer 1k;
    }
}

This work in C#:

private void dataGridView1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e)
{
    int idx = e.RowIndex;
    DataGridViewRow row = dataGridView1.Rows[idx];
    long newNo = idx;
    if (!_RowNumberStartFromZero)
        newNo += 1;

    long oldNo = -1;
    if (row.HeaderCell.Value != null)
    {
        if (IsNumeric(row.HeaderCell.Value))
        {
            oldNo = System.Convert.ToInt64(row.HeaderCell.Value);
        }
    }

    if (newNo != oldNo)
    {
        row.HeaderCell.Value = newNo.ToString();
        row.HeaderCell.Style.Alignment = DataGridViewContentAlignment.MiddleRight;
    }
}

I had a similar problem. I had a char* buffer with the .so name in it.
I could not convert the char* variable to LPCTSTR. Here's how I got around it...

char *fNam;
...
LPCSTR nam = fNam;
dll = LoadLibraryA(nam);

I know I'm am very late on this, but here some usefull samples:

'select the used cells in column 3 of worksheet wks
wks.columns(3).SpecialCells(xlCellTypeConstants).Select

or

'change all formulas in col 3 to values
with sheet1.columns(3).SpecialCells(xlCellTypeFormulas)
    .value = .value
end with

To find the last used row in column, never rely on LastCell, which is unreliable (it is not reset after deleting data). Instead, I use someting like

 lngLast = cells(rows.count,3).end(xlUp).row

According to documentation mod_ssl:

SSLCertificateFile: 
   Name: SSLCertificateFile
   Description: Server PEM-encoded X.509 certificate file

Certificate file should be PEM-encoded X.509 Certificate file:

openssl x509 -inform DER -in certificate.cer -out certificate.pem

You could open a command prompt, CD to the Debug or Release folder, and type the name of your exe. When I suggest this to people they think it is a lot of work, but here are the bare minimum clicks and keystrokes for this:

• in Visual Studio, right click your project in Solution Explorer or the tab with the file name if you have a file in the solution open, and choose Open Containing Folder or Open in Windows Explorer
• in the resulting Windows Explorer window, double-click your way to the folder with the exe
• Shift-right-click in the background of the explorer window and choose Open Commmand Window here
• type the first letter of your executable and press tab until the full name appears
• press enter

I think that's 14 keystrokes and clicks (counting shift-right-click as two for example) which really isn't much. Once you have the command prompt, of course, running it again is just up-arrow, enter.

I would like to improve Evan Knowles answer: https://stackoverflow.com/a/30796829/2628125

In my case I had class with handlers for UI Component part. Initialization:

this.dataText.textProperty().addListener((observable, oldValue, newValue) -> this.numericSanitization(observable, oldValue, newValue));

And the numbericSanitization method:

private synchronized void numericSanitization(ObservableValue<? extends String> observable, String oldValue, String newValue) {
    final String allowedPattern = "\\d*";

    if (!newValue.matches(allowedPattern)) {
        this.dataText.setText(oldValue);
    }
}

Keyword synchronized is added to prevent possible render lock issue in javafx if setText will be called before old one is finished execution. It is easy to reproduce if you will start typing wrong chars really fast.

Another advantage is that you keep only one pattern to match and just do rollback. It is better because you can easily abstragate solution for different sanitization patterns.

Make sure to select your database in this award winning GUI:

Everything in the java.lang package is implicitly imported (including String) and you do not need to do so yourself. This is simply a feature of the Java language. ArrayList and HashMap are however in the java.util package, which is not implicitly imported.

The package java.lang mostly includes essential features, such a class version of primitives, basic exceptions and the Object class. This being integral to most programs, forcing people to import them is redundant and thus the contents of this package are implicitly imported.

System.Linq has ToList() on IQueryable<> and IEnumerable<>. It will cause a full pass through the data to put it into a list, though. You loose your deferred invoke when you do this. Not a big deal if it is the consumer of the data.

You could also use React's useState hook to declare local state for a function component. The initial state of the variable toggled has been passed as an argument to the method .useState.

import { render } from 'react-dom';
import React from "react";

type Props = {
  text: string,
  onClick(event: React.MouseEvent<HTMLButtonElement>): void,
};

export function HelloWorldButton(props: Props) {
  const [toggled, setToggled] = React.useState(false); // returns a stateful value, and a function to update it
  return <button
  onClick={(event) => {
    setToggled(!toggled);
    props.onClick(event);
  }}
  >{props.text} (toggled: {toggled.toString()})</button>;
}


render(<HelloWorldButton text='Hello World' onClick={() => console.log('clicked!')} />, document.getElementById('root'));

You want to take advantage of the inserted logical table that is available in the context of a trigger. It matches the schema for the table that is being inserted to and includes the row(s) that will be inserted (in an update trigger you have access to the inserted and deleted logical tables which represent the the new and original data respectively.)

So to insert Employee / Department pairs that do not currently exist you might try something like the following.

CREATE TRIGGER trig_Update_Employee
ON [EmployeeResult]
FOR INSERT
AS
Begin
    Insert into Employee (Name, Department) 
    Select Distinct i.Name, i.Department 
    from Inserted i
    Left Join Employee e
    on i.Name = e.Name and i.Department = e.Department
    where e.Name is null
End

If you want to always prune when you fetch, I can suggest to use Aliases.

Just type git config -e to open your editor and change the configuration for a specific project and add a section like

[alias]
pfetch = fetch --prune   

the when you fetch with git pfetch the prune will be done automatically.

package-lock.json: It contains the exact version details that is currently installed for your Application.

UINavigationBar *nbar = self.navigationController.navigationBar;

if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {
   //iOS 7
   nbar.barTintColor = [UIColor blueColor]; // bar color
   //or custom color 
   //[UIColor colorWithRed:19.0/255.0 green:86.0/255.0 blue:138.0/255.0 alpha:1];

   nbar.navigationBar.translucent = NO;

   nbar.tintColor = [UIColor blueColor]; //bar button item color

} else {
   //ios 4,5,6
   nbar.tintColor = [UIColor whiteColor];
   //or custom color
   //[UIColor colorWithRed:19.0/255.0 green:86.0/255.0 blue:138.0/255.0 alpha:1];

Answer: From php 5.3 and >, the var keyword is equivalent to public when declaring variables inside a class.

class myClass {
  var $x;
}

is the same as (for php 5.3 and >):

class myClass {
  public $x;
}

History: It was previously the norm for declaring variables in classes, though later became depreciated, but later (PHP 5.3) it became un-depreciated.

echo "Hi All" | tr "[:upper:]" "[:lower:]"

I'm surprised that nobody has mentioned the use of this in the event handler. It works automatically in modern browsers and can be made to work in other browsers. If you use addEventListener or attachEvent to install your event handler, then you can make the value of this automatically be assigned to the object the created the event.

Further, the user of programmatically installed event handlers allows you to separate javascript code from HTML which is often considered a good thing.

Here's how you would do that in your code in plain javascript:

Remove the onmouseover="zoom()" from your HTML and install the event handler in your javascript like this:

// simplified utility function to register an event handler cross-browser
function setEventHandler(obj, name, fn) {
    if (typeof obj == "string") {
        obj = document.getElementById(obj);
    }
    if (obj.addEventListener) {
        return(obj.addEventListener(name, fn));
    } else if (obj.attachEvent) {
        return(obj.attachEvent("on" + name, function() {return(fn.call(obj));}));
    }
}

function zoom() {
    // you can use "this" here to refer to the object that caused the event
    // this here will refer to the calling object (which in this case is the <map>)
    console.log(this.id);
    document.getElementById("preview").src="http://photos.smugmug.com/photos/344290962_h6JjS-Ti.jpg";
}

// register your event handler
setEventHandler("nose", "mouseover", zoom);

Here's a solution that works with fixed backgrounds, if you have a fixed background and you have some overlayed elements and you need blured backgrounds for them, this solution works:

Image we have this simple HTML:

<body> <!-- or any wrapper -->
   <div class="content">Some Texts</div>
</body>

A fixed background for <body> or the wrapper element:

body {
  background-image: url(http://placeimg.com/640/360/any);
  background-size: cover;
  background-repeat: no-repeat;
  background-attachment: fixed;
}

And here for example we have a overlayed element with a white transparent background:

.content {
  background-color: rgba(255, 255, 255, 0.3);
  position: relative;
}

Now we need to use the exact same background image of our wrapper for our overlay elements too, i use it as a :before psuedo-class:

.content:before {
  content: '';
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  z-index: -1;
  filter: blur(5px);
  background-image: url(http://placeimg.com/640/360/any);
  background-size: cover;
  background-repeat: no-repeat;
  background-attachment: fixed;
}

Since the fixed background works in a same way in both wrapper and overlayed elements, we have the background in exactly same scroll position of the overlayed element and we can simply blur it. Here's a working fiddle, tested in Firefox, Chrome, Opera and Edge: https://jsfiddle.net/0vL2rc4d/

NOTE: In firefox there's a bug that makes screen flicker when scrolling and there are fixed blurred backgrounds. if there's any fix, let me know

You can use AtomicReference when applying optimistic locks. You have a shared object and you want to change it from more than 1 thread.

1. You can create a copy of the shared object
2. Modify the shared object
3. You need to check that the shared object is still the same as before - if yes, then update with the reference of the modified copy.

As other thread might have modified it and/can modify between these 2 steps. You need to do it in an atomic operation. this is where AtomicReference can help

JavaSun recomendation is to use a shared variable as a flag which asks the background thread to stop. This variable can then be set by a different object requesting the thread to terminate.

You can that way kill the other process, and the current one afterwards.

I would be inclined to this which has the virtue of IE8 support.

My situation was that I was out of inodes and I had already deleted about everything I could.

$ df -i
Filesystem     Inodes  IUsed  IFree IUse% Mounted on
/dev/sda1      942080 507361     11  100% /

I am on an ubuntu 12.04LTS and could not remove the old linux kernels which took up about 400,000 inodes because apt was broken because of a missing package. And I couldn't install the new package because I was out of inodes so I was stuck.

I ended up deleting a few old linux kernels by hand to free up about 10,000 inodes

$ sudo rm -rf /usr/src/linux-headers-3.2.0-2*

This was enough to then let me install the missing package and fix my apt

$ sudo apt-get install linux-headers-3.2.0-76-generic-pae

and then remove the rest of the old linux kernels with apt

$ sudo apt-get autoremove

things are much better now

$ df -i
Filesystem     Inodes  IUsed  IFree IUse% Mounted on
/dev/sda1      942080 507361 434719   54% /

Yes, NSDictionary supports fast enumeration. With Objective-C 2.0, you can do this:

// To print out all key-value pairs in the NSDictionary myDict
for(id key in myDict)
    NSLog(@"key=%@ value=%@", key, [myDict objectForKey:key]);

The alternate method (which you have to use if you're targeting Mac OS X pre-10.5, but you can still use on 10.5 and iPhone) is to use an NSEnumerator:

NSEnumerator *enumerator = [myDict keyEnumerator];
id key;
// extra parens to suppress warning about using = instead of ==
while((key = [enumerator nextObject]))
    NSLog(@"key=%@ value=%@", key, [myDict objectForKey:key]);

Polynomial time.

A polynomial is a sum of terms that look like Constant * x^k Exponential means something like Constant * k^x

(in both cases, k is a constant and x is a variable).

The execution time of exponential algorithms grows much faster than that of polynomial ones.

There is another away if you don't like to change System locale but the JVM. you can setup a System (or user) Environment variable JAVA_TOOL_OPTIONS and set its value to -Duser.language=en-US or any other language-REGION you want.

Would all these dates be in the database already or do you just want to know the days between the two dates? If it's the first you could use the BETWEEN or <= >= to find the dates between

EXAMPLE:

SELECT column_name(s)
FROM table_name
WHERE column_name
BETWEEN value1 AND value2

OR

SELECT column_name(s)
FROM table_name
WHERE column_name
value1 >= column_name
AND column_name =< value2

 $result= mysql_query("SELECT * FROM MY_TABLE");
 while($row = mysql_fetch_array($result)){
      echo $row['whatEverColumnName'];
 }

Use ContentProvider for inserting the bulk data in db. The below method used for inserting bulk data in to database. This should Improve INSERT-per-second performance of SQLite.

private SQLiteDatabase database;
database = dbHelper.getWritableDatabase();

public int bulkInsert(@NonNull Uri uri, @NonNull ContentValues[] values) {

database.beginTransaction();

for (ContentValues value : values)
 db.insert("TABLE_NAME", null, value);

database.setTransactionSuccessful();
database.endTransaction();

}

Call bulkInsert method :

App.getAppContext().getContentResolver().bulkInsert(contentUriTable,
            contentValuesArray);

You can replace it with its clone like so

var clone = $('#control').clone();

$('#control').replacewith(clone);

But this clones with its value too so you had better like so

var emtyValue = $('#control').val('');
var clone = emptyValue.clone();

$('#control').replacewith(clone);

Based on analysis done by Google-Chrome Dev Tools' Lighthouse Audit,

For users on slow connections, external scripts dynamically injected via document.write() can delay page load by tens of seconds.

use this code ,it will automatically refresh in 5 seconds, you can change time in refresh

<?php $url1=$_SERVER['REQUEST_URI']; header("Refresh: 5; URL=$url1"); ?>

For those looking a more modern approach, you can use the fetch API. The following example shows how to download a PDF file. It is easily done with the following code.

fetch(url, {
    body: JSON.stringify(data),
    method: 'POST',
    headers: {
        'Content-Type': 'application/json; charset=utf-8'
    },
})
.then(response => response.blob())
.then(response => {
    const blob = new Blob([response], {type: 'application/pdf'});
    const downloadUrl = URL.createObjectURL(blob);
    const a = document.createElement("a");
    a.href = downloadUrl;
    a.download = "file.pdf";
    document.body.appendChild(a);
    a.click();
})

I believe this approach to be much easier to understand than other XMLHttpRequest solutions. Also, it has a similar syntax to the jQuery approach, without the need to add any additional libraries.

Of course, I would advise checking to which browser you are developing, since this new approach won't work on IE. You can find the full browser compatibility list on the following [link][1].

Important: In this example I am sending a JSON request to a server listening on the given url. This url must be set, on my example I am assuming you know this part. Also, consider the headers needed for your request to work. Since I am sending a JSON, I must add the Content-Type header and set it to application/json; charset=utf-8, as to let the server know the type of request it will receive.

SIMPLY, You must set initial state first

If you don't set initial state react will treat that as an uncontrolled component

I'm freshly new with Pandas but I wanted to achieve the same thing, automatically avoiding column names with _x or _y and removing duplicate data. I finally did it by using this answer and this one from Stackoverflow

sales.csv

    city;state;units
    Mendocino;CA;1
    Denver;CO;4
    Austin;TX;2

revenue.csv

    branch_id;city;revenue;state_id
    10;Austin;100;TX
    20;Austin;83;TX
    30;Austin;4;TX
    47;Austin;200;TX
    20;Denver;83;CO
    30;Springfield;4;I

merge.py import pandas

def drop_y(df):
    # list comprehension of the cols that end with '_y'
    to_drop = [x for x in df if x.endswith('_y')]
    df.drop(to_drop, axis=1, inplace=True)


sales = pandas.read_csv('data/sales.csv', delimiter=';')
revenue = pandas.read_csv('data/revenue.csv', delimiter=';')

result = pandas.merge(sales, revenue,  how='inner', left_on=['state'], right_on=['state_id'], suffixes=('', '_y'))
drop_y(result)
result.to_csv('results/output.csv', index=True, index_label='id', sep=';')

When executing the merge command I replace the _x suffix with an empty string and them I can remove columns ending with _y

output.csv

    id;city;state;units;branch_id;revenue;state_id
    0;Denver;CO;4;20;83;CO
    1;Austin;TX;2;10;100;TX
    2;Austin;TX;2;20;83;TX
    3;Austin;TX;2;30;4;TX
    4;Austin;TX;2;47;200;TX

As commented by Chris, enums require much more memory on Android that adds up as they keep being used everywhere. You should try IntDef or StringDef instead, which use annotations so that the compiler validates passed values.

public abstract class ActionBar {
...
@IntDef({NAVIGATION_MODE_STANDARD, NAVIGATION_MODE_LIST, NAVIGATION_MODE_TABS})
@Retention(RetentionPolicy.SOURCE)
public @interface NavigationMode {}

public static final int NAVIGATION_MODE_STANDARD = 0;
public static final int NAVIGATION_MODE_LIST = 1;
public static final int NAVIGATION_MODE_TABS = 2;

@NavigationMode
public abstract int getNavigationMode();

public abstract void setNavigationMode(@NavigationMode int mode);

It can also be used as flags, allowing for binary composition (OR / AND operations).

EDIT: It seems that transforming enums into ints is one of the default optimizations in Proguard.

Use Gson library to convert ArrayList to JsonArray.

Gson gson = new GsonBuilder().create();
JsonArray myCustomArray = gson.toJsonTree(myCustomList).getAsJsonArray();

Try something like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    Write-Host $_.Exception.ToString()
}

The exception is in the $_ variable. You might explore $_ like this:

try {
    $w = New-Object net.WebClient
    $d = $w.downloadString('http://foo')
}
catch [Net.WebException] {
    $_ | fl * -Force
}

I think it will give you all the info you need.

My rule: if there is some data that is not displayed, try to use -force.

A call to EntityManager.flush(); will force the data to be persist in the database immediately as EntityManager.persist() will not (depending on how the EntityManager is configured : FlushModeType (AUTO or COMMIT) by default it's set to AUTO and a flush will be done automatically by if it's set to COMMIT the persitence of the data to the underlying database will be delayed when the transaction is commited).

StrSubstitutor of jakarta commons lang is a light weight way of doing this provided your values are already formatted correctly.

http://commons.apache.org/proper/commons-lang/javadocs/api-3.1/org/apache/commons/lang3/text/StrSubstitutor.html

Map<String, String> values = new HashMap<String, String>();
values.put("value", x);
values.put("column", y);
StrSubstitutor sub = new StrSubstitutor(values, "%(", ")");
String result = sub.replace("There's an incorrect value '%(value)' in column # %(column)");

The above results in:

"There's an incorrect value '1' in column # 2"

When using Maven you can add this dependency to your pom.xml:

<dependency>
    <groupId>org.apache.commons</groupId>
    <artifactId>commons-lang3</artifactId>
    <version>3.4</version>
</dependency>

I've just experienced this issue. For me it appeared when some erroneous code was trying to redirect to HTTPS on port 80.

e.g.

https://example.com:80/some/page

by removing the port 80 from the url, the redirect works.

HTTPS by default runs over port 443.

Window Page Scrollbar clickable when Modal is open

This one works for me. Pure CSS.

<style type="text/css">

body.modal-open {
padding-right: 17px !important;
}

.modal-backdrop.in {
margin-right: 16px; 

</style>

Try it and let me know

Enter a guid in your assembly data. Add this guid to the registry. Enter a reg key where the application read it's own name and add the name as value there.

The other task watcher read the reg key and knows the app name.

User vertical-align: middle; along with text-align: center property

<!DOCTYPE html>
<html>
<head>
<style>
.center {
  border: 3px solid green;
  text-align: center;
}

.center p {
  display: inline-block;
  vertical-align: middle;
}
</style>
</head>
<body>

<h2>Centering</h2>
<p>In this example, we use the line-height property with a value that is equal to the height property to center the div element:</p>

<div class="center">
  <p>I am vertically and horizontally centered.</p>
</div>

</body>
</html>

To search the whole computer:

gdr -PSProvider 'FileSystem' | %{ ls -r $.root} 2>$null | where { $.name -eq "httpd.exe" }

I am pretty sure this is a much less efficient command, for MANY reasons, but the simplest is your piping everything to your where-object command, when you could still use -filter "httpd.exe" and save a ton of cycles.

Also, on a lot of computers the get-psdrive is gonna grab shared drives, and I am pretty sure you wanted that to get a complete search. Most shares can be IMMENSE with regard to the sheer number of files and folders, so at the very least I would sort my drives by size, and add a check after each search to exit the loop if we locate the file. That is if you are looking for a single instance, if not the only way to save yourself the IMMENSE time sink of searching a 10TB share or two, is to comment the command and highly suggest any user who were to need to use it should limit their search as much as they can. For instance our User Profile share is 10TB, at least the one I am on is, and I can limit my search to the directory $sharedrive\users\myname and search my 116GB directory rather than the 10TB one. Too many unknowns with shares for this type of script, which is already super inefficient with regard to resources and speed.

If I was seriously considering using something like this, I would add a call to a 3rd party package and leverage a DB.

I found this subject researching. There is a way to copy all this data to an Excel Datasheet. (I have this problem before with a 50 million line CSV file) If there is any format, additional code could be included. Try this.

Sub ReadCSVFiles()

Dim i, j As Double
Dim UserFileName As String
Dim strTextLine As String
Dim iFile As Integer: iFile = FreeFile

UserFileName = Application.GetOpenFilename
Open UserFileName For Input As #iFile
i = 1
j = 1
Check = False

Do Until EOF(1)
    Line Input #1, strTextLine
    If i >= 1048576 Then
        i = 1
        j = j + 1
    Else
        Sheets(1).Cells(i, j) = strTextLine
        i = i + 1
    End If
Loop
Close #iFile
End Sub

If every element in b has different lengths, then you need to do something like:

int totalLength = 0;
for_every_element_in_b {
    totalLength += length_of_this_b_in_bytes;
}
return (char **)malloc(totalLength);

If all your trying to do is fill the div this might help someone else, if aspect ratio is not important, is responsive.

.img-fill > img {
  min-height: 100%;
  min-width: 100%;  
}

On Ubuntu the flatpak version seemed broken. I uninstalled it and downloaded the deb package right from Microsoft.

Try

SELECT dbo.function (parameters)

You can use this code from firebase github samples ..

You don't need to edit in layout files ... just make a new class "BaseActivity"

package com.example;

import android.app.ProgressDialog;
import android.support.annotation.VisibleForTesting;
import android.support.v7.app.AppCompatActivity;


public class BaseActivity extends AppCompatActivity {

    @VisibleForTesting
    public ProgressDialog mProgressDialog;

    public void showProgressDialog() {
        if (mProgressDialog == null) {
            mProgressDialog = new ProgressDialog(this);
            mProgressDialog.setMessage("Loading ...");
            mProgressDialog.setIndeterminate(true);
        }

        mProgressDialog.show();
    }


    public void hideProgressDialog() {
        if (mProgressDialog != null && mProgressDialog.isShowing()) {
            mProgressDialog.dismiss();
        }
    }

    @Override
    public void onStop() {
        super.onStop();
        hideProgressDialog();
    }

}

In your Activity that you want to use the progress dialog ..

public class MyActivity extends BaseActivity

Before/After the function that take time

showProgressDialog();
.... my code that take some time
showProgressDialog();

One way of finding all data attributes is using element.attributes. Using .attributes, you can loop through all of the element attributes, filtering out the items which include the string "data-".

let element = document.getElementById("element");

function getDataAttributes(element){
    let elementAttributes = {},
        i = 0;

    while(i < element.attributes.length){
        if(element.attributes[i].name.includes("data-")){
            elementAttributes[element.attributes[i].name] = element.attributes[i].value
        }
        i++;
    }

    return elementAttributes;

}

Try this

padding:8px;
overflow: hidden;
zoom: 1;
text-align: left;
font-size: 13px;
font-family: "Trebuchet MS",Arial,Sans;
line-height: 24px;
color: black;
border-bottom: solid 1px #BBB;
background:url('images/checked.gif') white no-repeat;

This is full css.. Why you use padding:0 8px, then override it with paddings? This is what you need...

CSS isn't going to be able to call other elements like that, you'll need to use JavaScript to reach beyond a child or sibling selector.

You could try something like this:

<a>Some Link
<div><img src="/you/image" /></div>
</a>

then...

a>div { display: none; }
a:hover>div { display: block; }

Give them a trivial pom with these jars listed as dependencies and instructions to run:

mvn dependency:go-offline

This will pull the dependencies to the local repo.

A more direct solution is dependency:get, but it's a lot of arguments to type:

mvn dependency:get -DrepoUrl=something -Dartifact=group:artifact:version

Given a Window object myWindow, myWindow.Show() will open it modelessly and myWindow.ShowDialog() will open it modally. However, even the latter doesn't block, from what I remember.

classic solution:

for f in $(find . -name "*dbg*"); do mv $f $(echo $f | sed 's/_dbg//'); done

Just use an <a> by itself, set it to display: block; and set width and height. Get rid of the <span> and <div>. This is the semantic way to do it. There is no need to wrap things in <divs> (or any element) for layout. That is what CSS is for.

Demo: http://jsfiddle.net/ThinkingStiff/89Enq/

HTML:

<a id="music" href="Music.html">Music I Like</a>

CSS:

#music {
    background-color: black;
    color: white;
    display: block;
    height: 40px;
    line-height: 40px;
    text-decoration: none;
    width: 100px;
    text-align: center;
}

Output:

Put them in public folder and call it in the view with something like href="{{ asset('public/css/style.css') }}". Note that the public should be included when you call the assets.

I got this error due to not pointing the script to the correct path. So make absolutely sure that you are pointing to the correct path in you html file.

Using label for= in html form

This could permit to visualy dissociate label(s) and object while keeping them linked.

Sample: there is a checkbox and two labels. You could check/uncheck the box by clicking indifferently on any label or on box, but not on text nor on input content...

<label for="demo1"> There is a label </label>
<br />
Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Duis sem velit, ultrices et, fermentum auctor, rhoncus ut, ligula. Phasellus at purus sed purus cursus iaculis. Suspendisse fermentum. Pellentesque et arcu. Maecenas viverra. In consectetuer, lorem eu lobortis egestas, velit odio imperdiet eros, sit amet sagittis nunc mi ac neque. Sed non ipsum. Nullam venenatis gravida orci.
<br />
<label for="demo1"> There is a 2nd label </label>
<input id="demo1" type="checkbox">Demo 1</input>

Some useful tricks

By use stylesheet CSS power, you could do a lot of interresting things...

#demo2:checked ~ .but2:before { content: 'Des'; }
#demo2:checked ~ .box2:before { content: '?'; }
.but2:before { content: 'S'; }
.box2:before { content: '?'; }
#demo1:checked ~ .but1:before { content: 'Des'; }
#demo1:checked ~ .box1:before { content: '?'; }
.but1:before { content: 'S'; }
.box1:before { content: '?'; }

<input id="demo1" type="checkbox">Demo 1</input>
<input id="demo2" type="checkbox">Demo 2</input>
<br />
<label for="demo1" class="but1">elect 2</label> - 
<label for="demo2" class="but2">elect 1</label>
<br />
Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Duis sem velit, ultrices et, fermentum auctor, rhoncus ut, ligula. Phasellus at purus sed purus cursus iaculis. Suspendisse fermentum. Pellentesque et arcu. Maecenas viverra. In consectetuer, lorem eu lobortis egestas, velit odio imperdiet eros, sit amet sagittis nunc mi ac neque. Sed non ipsum. Nullam venenatis gravida orci.
<br />
<label for="demo1" class="but1">elect this 2nd label </label> - 
<label class="but2" for="demo2">elect this another 2nd label </label>
<br />
<label for="demo1" class="box1"> check 1</label>
<label for="demo2" class="box2"> check 2</label> 

There's another trick you can use to show columns from previous rows, using any ordering you want, using a variable similar to the @row trick:

SELECT @prev_col_a, @prev_col_b, @prev_col_c,
   @prev_col_a := col_a AS col_a,
   @prev_col_b := col_b AS col_b,
   @prev_col_c := col_c AS col_c
FROM table, (SELECT @prev_col_a := NULL, @prev_col_b := NULL, @prev_col_c := NULL) prv
ORDER BY whatever

Apparently, the select columns are evaluated in order, so this will first select the saved variables, and then update the variables to the new row (selecting them in the process).

NB: I'm not sure that this is defined behaviour, but I've used it and it works.

Add a border to the regular item, the same color as the background, so that it cannot be seen. That way the item has a border: 1px whether it is being hovered or not.

In phpmyadmin, If you need to add a boolean datatype column to an existing table with default value true:

ALTER TABLE books
   isAvailable boolean default true;

Neither main() or void main() are standard C. The former is allowed as it has an implicit int return value, making it the same as int main(). The purpose of main's return value is to return an exit status to the operating system.

In standard C, the only valid signatures for main are:

int main(void)

and

int main(int argc, char **argv)

The form you're using: int main() is an old style declaration that indicates main takes an unspecified number of arguments. Don't use it - choose one of those above.
