You can use git checkout.

I tried the accepted solution but got an error, warning: refname '<tagname>' is ambiguous'

But as the answer states, tags do behave like a pointer to a commit, so as you would with a commit hash, you can just checkout the tag. The only difference is you preface it with tags/:

git checkout tags/<tagname>

I would suggest following design : Item Table: Itemid, taglist1, taglist2
this will be fast and make easy saving and retrieving the data at item level.

In parallel build another table: Tags tag do not make tag unique identifier and if you run out of space in 2nd column which contains lets say 100 items create another row.

Now while searching for items for a tag it will be super fast.

One item is going to have many tags. And one tag will belong to many items. This implies to me that you'll quite possibly need an intermediary table to overcome the many-to-many obstacle.

Something like:

Table: Items
Columns: Item_ID, Item_Title, Content

Table: Tags
Columns: Tag_ID, Tag_Title

Table: Items_Tags
Columns: Item_ID, Tag_ID

It might be that your web app is very very popular and need de-normalizing down the road, but it's pointless muddying the waters too early.

You can find information and a little description of the MBDB/MBDX format here:

http://code.google.com/p/iphonebackupbrowser/

This is my application to browse the backup files. I have tried to document the format of the new files that come with iTunes 9.2.

The reason for using POST when making changes to data:

• A web accelerator like Google Web Accelerator will click all (GET) links on a page and cache them. This is very bad if the links make changes to things.
• A browser caches GET requests so even if the user clicks the link it may not send a request to the server to execute the change.
• To protect your site/application against CSRF you must use POST. To completely secure your app you must then also generate a unique identifier on the server and send that along in the request.

Also, don't put sensitive information in the query string (only option with GET) because it shows up in the address bar, bookmarks and server logs.

Hopefully this explains why people say POST is 'secure'. If you are transmitting sensitive data you must use SSL.

pt is a derivation (abbreviation) of "point" which historically was used in print type faces where the size was commonly "measured" in "points" where 1 point has an approximate measurement of 1/72 of an inch, and thus a 72 point font would be 1 inch in size.

px is an abbreviation for "pixel" which is a simple "dot" on either a screen or a dot matrix printer or other printer or device which renders in a dot fashion - as opposed to old typewriters which had a fixed size, solid striker which left an imprint of the character by pressing on a ribbon, thus leaving an image of a fixed size.

Closely related to point are the terms "uppercase" and "lowercase" which historically had to do with the selection of the fixed typographical characters where the "captital" characters where placed in a box (case) above the non-captitalized characters which were place in a box below, and thus the "lower" case.

There were different boxes (cases) for different typographical fonts and sizes, but still and "upper" and "lower" case for each of those.

Another term is the "pica" which is a measure of one character in the font, thus a pica is 1/6 of an inch or 12 point units of measure (12/72) of measure.

Strickly speaking the measurement is on computers 4.233mm or 0.166in whereas the old point (American) is 1/72.27 of an inch and French is 4.512mm (0.177in.). Thus my statement of "approximate" regarding the measurements.

Further, typewriters as used in offices, had either and "Elite" or a "Pica" size where the size was 10 and 12 characters per inch repectivly.

Additionally, the "point", prior to standardization was based on the metal typographers "foot" size, the size of the basic footprint of one character, and varied somewhat in size.

Note that a typographical "foot" was originally from a deceased printers actual foot. A typographic foot contains 72 picas or 864 points.

As to CSS use, I prefer to use EM rather than px or pt, thus gaining the advantage of scaling without loss of relative location and size.

EDIT: Just for completeness you can think of EM (em) as an element of measure of one font height, thus 1em for a 12pt font would be the height of that font and 2em would be twice that height. Note that for a 12px font, 2em is 24 pixels. SO 10px is typically 0.63em of a standard font as "most" browsers base on 16px = 1em as a standard font size.

To complete the work of @VFDan, I benchmarked the 3 methods: the accepted one (custom loop), reduce, and find(max(arr)) on an array of 10000 floats.

Results on chromimum 85 linux (higher is better):

• custom loop: 100%
• reduce: 94.36%
• indexOf(max): 70%

Results on firefox 80 linux (higher is better):

• custom loop: 100%
• reduce: 96.39%
• indexOf(max): 31.16%

Conclusion:

If you need your code to run fast, don't use indexOf(max). reduce is ok but use the custom loop if you need the best performances.

You can run this benchmark on other browser using this link: https://jsben.ch/wkd4c

gunzip <filename>

then

tar -xvf <tar-file-name>

This is very simple:

import numpy as np

list_of_lists = np.array(df)

You can remove the time part of a date by using TRUNC.

select field,datetime_field 
  from database
 where datetime_field >= trunc(sysdate-1,'DD');

That query will give you all rows with dates starting from yesterday. Note the second argument to trunc(). You can use this to truncate any part of the date.

If your datetime_fied contains '2011-05-04 08:23:54', the following date will be returned

trunc(datetime_field, 'HH24') => 2011-05-04 08:00:00
trunc(datetime_field, 'DD')   => 2011-05-04 00:00:00
trunc(datetime_field, 'MM')   => 2011-05-01 00:00:00
trunc(datetime_field, 'YYYY') => 2011-00-01 00:00:00

I got this on Firefox (FF58). I fixed this with:

1. It is still experimental on Firefox (from v54): You have to set to true the variable dom.moduleScripts.enabled in about:config

Source: Import page on mozilla (See Browser compatibility)

2. Add type="module" to your script tag where you import the js file

<script type="module" src="appthatimports.js"></script>

3. Import files have to be prefixed (./, /, ../ or http:// before)

import * from "./mylib.js"

For more examples, this blog post is good.

Remove these two lines:

xmlHttp.setRequestHeader("Content-length", params.length);
xmlHttp.setRequestHeader("Connection", "close");

XMLHttpRequest isn't allowed to set these headers, they are being set automatically by the browser. The reason is that by manipulating these headers you might be able to trick the server into accepting a second request through the same connection, one that wouldn't go through the usual security checks - that would be a security vulnerability in the browser.

Straight from nodejs's API docs on Console

const output = fs.createWriteStream('./stdout.log');
const errorOutput = fs.createWriteStream('./stderr.log');
// custom simple logger
const logger = new Console(output, errorOutput);
// use it like console
const count = 5;
logger.log('count: %d', count);
// in stdout.log: count 5

First off, the extern keyword is not used for defining a variable; rather it is used for declaring a variable. I can say extern is a storage class, not a data type.

extern is used to let other C files or external components know this variable is already defined somewhere. Example: if you are building a library, no need to define global variable mandatorily somewhere in library itself. The library will be compiled directly, but while linking the file, it checks for the definition.

There are many possible ways to cause a docker to exit immediately. For me, it was the problem with my Dockerfile. There was a bug in that file. I had ENTRYPOINT ["dotnet", "M4Movie_Api.dll] instead of ENTRYPOINT ["dotnet", "M4Movie_Api.dll"]. As you can see I had missed one quotation(") at the end.

To analyze the problem I started my container and quickly attached my container so that I could see what was the exact problem.

C:\SVenu\M4Movie\Api\Api>docker start 4ea373efa21b


C:\SVenu\M4Movie\Api\Api>docker attach 4ea373efa21b

Where 4ea373efa21b is my container id. This drives me to the actual issue.

After finding the issue, I had to build, restore, publish my container again.

EDIT: I realized a little late that it was bound to a DataTable. In that case the idea is the same, and you can cast to a DataRowView then take its Row property to get a DataRow if you want to work with that class.

foreach (var item in checkedListBox1.CheckedItems)
{
    var row = (item as DataRowView).Row;
    MessageBox.Show(row["ID"] + ": " + row["CompanyName"]);
}

You would need to cast or parse the items to their strongly typed equivalents, or use the System.Data.DataSetExtensions namespace to use the DataRowExtensions.Field method demonstrated below:

foreach (var item in checkedListBox1.CheckedItems)
{
    var row = (item as DataRowView).Row;
    int id = row.Field<int>("ID");
    string name = row.Field<string>("CompanyName");
    MessageBox.Show(id + ": " + name);
}

You need to cast the item to access the properties of your class.

foreach (var item in checkedListBox1.CheckedItems)
{
    var company = (Company)item;
    MessageBox.Show(company.Id + ": " + company.CompanyName);
}

Alternately, you could use the OfType extension method to get strongly typed results back without explicitly casting within the loop:

foreach (var item in checkedListBox1.CheckedItems.OfType<Company>())
{
    MessageBox.Show(item.Id + ": " + item.CompanyName);
}

Consider using a Spinner instead of a Number Picker in a Dialog. It's not exactly what was asked for, but it's much easier to implement, more contextual UI design, and should fulfill most use cases. The equivalent code for a Spinner is:

Spinner picker = new Spinner(this);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_spinner_item, yourStringList);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
picker.setAdapter(adapter);

For creating session only cookie with java script, you can use the following. This works for me.

document.cookie = "cookiename=value; expires=0; path=/";

then get cookie value as following

 //get cookie 
var cookiename = getCookie("cookiename");
if (cookiename == "value") {
    //write your script
}

//function getCookie        
function getCookie(cname) {
    var name = cname + "=";
    var ca = document.cookie.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') c = c.substring(1);
        if (c.indexOf(name) != -1) return c.substring(name.length, c.length);
    }
    return "";
}

Okay to support IE we can leave "expires" completely and can use this

document.cookie = "mtracker=somevalue; path=/";

Meteor's strength is in it's real-time updates feature which works well for some of the social applications you see nowadays where you see everyone's updates for what you're working on. These updates center around replicating subsets of a MongoDB collection underneath the covers as local mini-mongo (their client side MongoDB subset) database updates on your web browser (which causes multiple render events to be fired on your templates). The latter part about multiple render updates is also the weakness. If you want your UI to control when the UI refreshes (e.g., classic jQuery AJAX pages where you load up the HTML and you control all the AJAX calls and UI updates), you'll be fighting this mechanism.

Meteor uses a nice stack of Node.js plugins (Handlebars.js, Spark.js, Bootstrap css, etc. but using it's own packaging mechanism instead of npm) underneath along w/ MongoDB for the storage layer that you don't have to think about. But sometimes you end up fighting it as well...e.g., if you want to customize the Bootstrap theme, it messes up the loading sequence of Bootstrap's responsive.css file so it no longer is responsive (but this will probably fix itself when Bootstrap 3.0 is released soon).

So like all "full stack frameworks", things work great as long as your app fits what's intended. Once you go beyond that scope and push the edge boundaries, you might end up fighting the framework...

Well, there is an array type in recent Postgres versions (not 100% about PG 7.4). You can even index them, using a GIN or GIST index. The syntaxes are:

create table foo (
  bar  int[] default '{}'
);

select * from foo where bar && array[1] -- equivalent to bar && '{1}'::int[]

create index on foo using gin (bar); -- allows to use an index in the above query

But as the prior answer suggests, it will be better to normalize properly.

int opcion = JOptionPane.showConfirmDialog(null, "Realmente deseas salir?", "Aviso", JOptionPane.YES_NO_OPTION);

if (opcion == 0) { //The ISSUE is here
   System.out.print("si");
} else {
   System.out.print("no");
}

If you are looking for the oldest date (minimum value), you'd sort and then take the first item returned. Sorry for the C#:

var min = myData.OrderBy( cv => cv.Date1 ).First();

The above will return the entire object. If you just want the date returned:

var min = myData.Min( cv => cv.Date1 );

Regarding which direction to go, re: Linq to Sql vs Linq to Entities, there really isn't much choice these days. Linq to Sql is no longer being developed; Linq to Entities (Entity Framework) is the recommended path by Microsoft these days.

From Microsoft Entity Framework 4 in Action (MEAP release) by Manning Press:

What about the future of LINQ to SQL?

It's not a secret that LINQ to SQL is included in the Framework 4.0 for compatibility reasons. Microsoft has clearly stated that Entity Framework is the recommended technology for data access. In the future it will be strongly improved and tightly integrated with other technologies while LINQ to SQL will only be maintained and little evolved.

Haven't tested it, but that should alert the blobs data url:

var blob = event.clipboardData.items[0].getAsFile(), 
    form = new FormData(),
    request = new XMLHttpRequest();

var reader = new FileReader();
reader.onload = function(event) {
  alert(event.target.result); // <-- data url
};
reader.readAsDataURL(blob);

Works for me. Notice the use of background-image for transition.

#poster-img {
  background-repeat: no-repeat;
  background-position: center;
  position: absolute;
  overflow: hidden;
  -webkit-transition: background-image 1s ease-in-out;
  transition: background-image 1s ease-in-out;
}

I ran into a similar problem while creating a library to handle authentication. I want the app owner using my library to be able to register a callback with the library for checking authorization against LDAP groups the authenticated person is in. The configuration is getting passed in as a config.py file that gets imported and contains a dict with all the config parameters.

I got this to work:

>>> class MyClass(object):
...     def target_func(self):
...         print "made it!"
...    
...     def __init__(self,config):
...         self.config = config
...         self.config['funcname'] = getattr(self,self.config['funcname'])
...         self.config['funcname']()
... 
>>> instance = MyClass({'funcname':'target_func'})
made it!

Is there a pythonic-er way to do this?

To summarize, for me following the two instructions above to change any instances where numberOfLines = 0 to 1 or greater, and manually adding preferredMaxLayoutWidth="0" to each instance of a label inside the storyboard source fixed all of my warnings.

Although some of them are correct, I've found quite confusing the previous responses. At the same time, the OP asked for a solution without setting a custom header or using beforeSend, so I've being looking for a clearer explanation. I hope my conclusions provide some light to others.

The code

jQuery.ajax({
    .... 
    accepts: "application/json; charset=utf-8",
    ....
});

doesn't work because accepts must be a PlainObject (not a String) according to the jQuery doc (http://api.jquery.com/jquery.ajax/). Specifically, jQuery expect zero or more key-value pairs relating each dataType with the accepted MIME type for them. So what I've finally using is:

jQuery.ajax({
    ....
    dataType: 'json',
    accepts: {
        json: 'application/json'
    },
    ....
});

if you want to execute the statement when number of rows are modified then it can be possible by statement level triggers.. viseversa... when you want to execute your statement each modification on your number of rows then you need to go for row level triggers..

for example: statement level triggers works for when table is modified..then more number of records are effected. and row level triggers works for when each row updation or modification..

Yes, this is something that you should worry about. Check the length of your objects with nrow(). R can auto-replicate objects so that they're the same length if they differ, which means you might be performing operations on mismatched data.

In this case you have an obvious flaw in that your subtracting aggregated data from raw data. These will definitely be of different lengths. I suggest that you merge them as time series (using the dates), then locf(), then do your subtraction. Otherwise merge them by truncating the original dates to the same interval as the aggregated series. Just be very careful that you don't drop observations.

Lastly, as some general advice as you get started: look at the result of your computations to see if they make sense. You might even pull them into a spreadsheet and replicate the results.

How a character is represented is up to the renderer, but the server may also strip out certain characters before sending the document.

You can also have untitled YouTube videos like https://www.youtube.com/watch?v=dmBvw8uPbrA by using the Unicode character ZERO WIDTH NON-JOINER (U+200C), or ‌ in HTML. The code block below should contain that character:

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

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

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

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

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

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

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

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

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

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

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

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

after that make changes like this:

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

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

<?

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

?>

cheers :-)

In my case i had set:

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

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

This is plain Javascript and has nothing to do with the jQuery library.

You simply escape the apostrophe with a backslash:

theAnchorText = 'I\'m home';

Another alternative is to use quotation marks around the string, then you don't have to escape apostrophes:

theAnchorText = "I'm home";

We can easily do it by using groupby and count. But, we should remember to use reset_index().

df[['col1','col2','col3','col4']].groupby(['col1','col2']).count().\
reset_index()

If you have an index and value. Then you can add to Series as:

obj = Series([4,7,-5,3])
obj.index=['a', 'b', 'c', 'd']

obj['e'] = 181

this will add a new value to Series (at the end of Series).

You can use * operator to unpack dict_values:

>>> d = {1: "a", 2: "b"}
>>> [*d.values()]
['a', 'b']

or list object

>>> d = {1: "a", 2: "b"}
>>> list(d.values())
['a', 'b']

Try adding the following to your JS on bootply

$('#myModal2').on('show.bs.modal', function () {  
$('#myModal').css('z-index', 1030); })

$('#myModal2').on('hidden.bs.modal', function () {  
$('#myModal').css('z-index', 1040); })

Explanation:

After playing around with the attributes(using Chrome's dev tool), I have realized that any z-index value below 1031 will put things behind the backdrop.

So by using bootstrap's modal event handles I set the z-index to 1030. If #myModal2 is shown and set the z-index back to 1040 if #myModal2 is hidden.

In case you want to handle intent on opened activity, you can use PendintIntent (Complete steps below):

public class SMSReciver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        final Bundle bundle = intent.getExtras();
        try {
            if (bundle != null) {
                final Object[] pdusObj = (Object[]) bundle.get("pdus");
                for (int i = 0; i < pdusObj.length; i++) {
                    SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                    String phoneNumber = currentMessage.getDisplayOriginatingAddress();
                    String senderNum = phoneNumber;
                    String message = currentMessage.getDisplayMessageBody();
                    try {
                        if (senderNum.contains("MOB_NUMBER")) {
                            Toast.makeText(context,"",Toast.LENGTH_SHORT).show();

                            Intent intentCall = new Intent(context, MainActivity.class);
                            intentCall.putExtra("message", currentMessage.getMessageBody());

                            PendingIntent pendingIntent= PendingIntent.getActivity(context, 0, intentCall, PendingIntent.FLAG_UPDATE_CURRENT);
                            pendingIntent.send();
                        }
                    } catch (Exception e) {
                    }
                }
            }
        } catch (Exception e) {
        }
    }
} 

manifest:

<activity android:name=".MainActivity"
            android:launchMode="singleTask"/>
<receiver android:name=".SMSReciver">
            <intent-filter android:priority="1000">
                <action android:name="android.provider.Telephony.SMS_RECEIVED"/>
            </intent-filter>
        </receiver>

onNewIntent:

 @Override
         protected void onNewIntent(Intent intent) {
                super.onNewIntent(intent);
                Toast.makeText(this, "onNewIntent", Toast.LENGTH_SHORT).show();

                onSMSReceived(intent.getStringExtra("message"));

            }

permissions:

<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.SEND_SMS" />

const a = {
  foods: {
    dinner: 'Pasta'
  }
}
let b = JSON.parse(JSON.stringify(a))
b.foods.dinner = 'Soup'
console.log(b.foods.dinner) // Soup
console.log(a.foods.dinner) // Pasta

Using JSON.stringify and JSON.parse is the best way. Because by using the spread operator we will not get the efficient answer when the json object contains another object inside it. we need to manually specify that.

Similar to the other examples, but using html sizing, I use:

<img src="image1.png" width="425"/> <img src="image2.png" width="425"/> 

Here is an example

I tested this using Remarkable.

Why didn't someone tell me I was being a total noob? All I had to do was copy the dateutil directory to someplace in my Python path, and it was good to go.

You could copy down a formula like the following in a new column...

=IF(ISNUMBER(FIND("-",A1)),1,0)

... then sort on that column, highlight all the rows where the value is 1 and delete them.

trick:

    int time_len = 0, n;
    struct tm *tm_info;
    struct timeval tv;

    gettimeofday(&tv, NULL);
    tm_info = localtime(&tv.tv_sec);
    time_len+=strftime(log_buff, sizeof log_buff, "%y%m%d %H:%M:%S", tm_info);
    time_len+=snprintf(log_buff+time_len,sizeof log_buff-time_len,".%03ld ",tv.tv_usec/1000);

The only solution worked for me was:

1. I opened a new tab in chrome
2. I pasted : http://localhost:8888/?token=......
3. then I went to my original notebook and I was able to save it

SELECT TRUNC(SYSDATE,'D') "1ST_DAY", TRUNC(SYSDATE,'D') + 6 LAST_DAY FROM DUAL

You can't modify the members of a CSS class on the fly. However, you could introduce a new <style> tag on the page with your new css class implementation, and then switch out the class. Example:

Sample.css

.someClass { border: 1px solid black; font-size: 20px; }

You want to change that class entirely, so you create a new style element:

<style>
   .someClassReplacement { border: 1px solid white; font-size: 14px; }       
</style>

You then do a simple replacement via jQuery:

$('.someClass').removeClass('someClass').addClass('someClassReplacement');

OK, this is a bad thing to be doing. Don't mock a list; instead, mock the individual objects inside the list. See Mockito: mocking an arraylist that will be looped in a for loop for how to do this.

Also, why are you using PowerMock? You don't seem to be doing anything that requires PowerMock.

But the real cause of your problem is that you are using when on two different objects, before you complete the stubbing. When you call when, and provide the method call that you are trying to stub, then the very next thing you do in either Mockito OR PowerMock is to specify what happens when that method is called - that is, to do the thenReturn part. Each call to when must be followed by one and only one call to thenReturn, before you do any more calls to when. You made two calls to when without calling thenReturn - that's your error.

In PHP, you use the self keyword to access static properties and methods.

The problem is that you can replace $this->method() with self::method()anywhere, regardless if method() is declared static or not. So which one should you use?

Consider this code:

class ParentClass {
    function test() {
        self::who();    // will output 'parent'
        $this->who();   // will output 'child'
    }

    function who() {
        echo 'parent';
    }
}

class ChildClass extends ParentClass {
    function who() {
        echo 'child';
    }
}

$obj = new ChildClass();
$obj->test();

In this example, self::who() will always output ‘parent’, while $this->who() will depend on what class the object has.

Now we can see that self refers to the class in which it is called, while $this refers to the class of the current object.

So, you should use self only when $this is not available, or when you don’t want to allow descendant classes to overwrite the current method.

getClientRects return the client rects like this and if you want to get the lines, use the follow function like this

function getRowRects(element) {
    var rects = [],
        clientRects = element.getClientRects(),
        len = clientRects.length,
        clientRect, top, rectsLen, rect, i;

    for(i=0; i<len; i++) {
        has = false;
        rectsLen = rects.length;
        clientRect = clientRects[i];
        top = clientRect.top;
        while(rectsLen--) {
            rect = rects[rectsLen];
            if (rect.top == top) {
                has = true;
                break;
            }
        }
        if(has) {
            rect.right = rect.right > clientRect.right ? rect.right : clientRect.right;
            rect.width = rect.right - rect.left;
        }
        else {
            rects.push({
                top: clientRect.top,
                right: clientRect.right,
                bottom: clientRect.bottom,
                left: clientRect.left,
                width: clientRect.width,
                height: clientRect.height
            });
        }
    }
    return rects;
}

You could use search or match for this.

str.search( 'Yes' )

will return the position of the match, or -1 if it isn't found.

If your UML modeling tool has support for specifying an Enumeration, you should use that. It will likely be easier to do and it will give your model stronger semantics. Visually the result will be very similar to a Class with an <<enumeration>> Stereotype, but in the UML metamodel, an Enumeration is actually a separate (meta)type.

+---------------------+
|   <<enumeration>>   |
|    DayOfTheWeek     |

| Tuesday             |
| ...                 |
+---------------------+

Once it is defined, you can use it as the type of an Attribute just like you would a Datatype or the name one of your own Classes.

If you're using ArgoEclipse or ArgoUML, there's a pulldown menu on the toolbar which selects among Datatype, Enumeration, Signal, etc that will allow you to create your own Enumerations. The compartment that normally contains Attributes can then be populated with EnumerationLiterals for the values of your enumeration.

Here's a picture of a slightly different example in ArgoUML:

To expand upon dreamlax's example... If you want to send data along with the notification

In posting code:

NSDictionary *userInfo = 
[NSDictionary dictionaryWithObject:myObject forKey:@"someKey"];
[[NSNotificationCenter defaultCenter] postNotificationName: 
                       @"TestNotification" object:nil userInfo:userInfo];

In observing code:

- (void) receiveTestNotification:(NSNotification *) notification {

    NSDictionary *userInfo = notification.userInfo;
    MyObject *myObject = [userInfo objectForKey:@"someKey"];
}

Swift 5 & Xcode 11

So in xCode 11 the window solution is no longer valid inside of appDelegate. They moved this to the SceneDelgate. You can find this in the SceneDelgate.swift file.

You will notice it now has a var window: UIWindow? present.

In my situation I was using a TabBarController from a storyboard and wanted to set it as the rootViewController.

This is my code:

sceneDelegate.swift

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
        // Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
        // If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
        // This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).

        self.window = self.window ?? UIWindow()//@JA- If this scene's self.window is nil then set a new UIWindow object to it.

        //@Grab the storyboard and ensure that the tab bar controller is reinstantiated with the details below.
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        let tabBarController = storyboard.instantiateViewController(withIdentifier: "tabBarController") as! UITabBarController

        for child in tabBarController.viewControllers ?? [] {
            if let top = child as? StateControllerProtocol {
                print("State Controller Passed To:")
                print(child.title!)
                top.setState(state: stateController)
            }
        }

        self.window!.rootViewController = tabBarController //Set the rootViewController to our modified version with the StateController instances
        self.window!.makeKeyAndVisible()

        print("Finished scene setting code")
        guard let _ = (scene as? UIWindowScene) else { return }
    }

Make sure to add this to the correct scene method as I did here. Note that you will need to set the identifier name for the tabBarController or viewController you are using in the storyboard.

In my case I was doing this to set a stateController to keep track of shared variables amongst the tab views. If you wish to do this same thing add the following code...

StateController.swift

import Foundation

struct tdfvars{
    var rbe:Double = 1.4
    var t1half:Double = 1.5
    var alphaBetaLate:Double = 3.0
    var alphaBetaAcute:Double = 10.0
    var totalDose:Double = 6000.00
    var dosePerFraction:Double = 200.0
    var numOfFractions:Double = 30
    var totalTime:Double = 168
    var ldrDose:Double = 8500.0
}

//@JA - Protocol that view controllers should have that defines that it should have a function to setState
protocol StateControllerProtocol {
  func setState(state: StateController)
}

class StateController {
    var tdfvariables:tdfvars = tdfvars()
}

Note: Just use your own variables or whatever you are trying to keep track of instead, I just listed mine as an example in tdfvariables struct.

In each view of the TabController add the following member variable.

    class SettingsViewController: UIViewController {
    var stateController: StateController?
.... }

Then in those same files add the following:

extension SettingsViewController: StateControllerProtocol {
  func setState(state: StateController) {
    self.stateController = state
  }
}

What this does is allows you to avoid the singleton approach to passing variables between the views. This allows easily for the dependency injection model which is much better long run then the singleton approach.

You can see all the version of a module with npm view. eg: To list all versions of bootstrap including beta.

npm view bootstrap versions

But if the version list is very big it will truncate. An --json option will print all version including beta versions as well.

npm view bootstrap versions --json

If you want to list only the stable versions not the beta then use singular version

npm view bootstrap@* versions

Or

npm view bootstrap@* versions --json

And, if you want to see only latest version then here you go.

npm view bootstrap version

It may work with any character from the HTML Escape character list, but I had the same problem with a Java project. I used StringEscapeUtils.escapeHTML("Testing \" <br> <p>") and the title was <a href=".." title="Test&quot; &lt;br&gt; &lt;p&gt;">Testing</a>.

It only worked for me when I changed the StringEscapeUtils to StringEscapeUtils.escapeJavascript("Testing \" <br> <p>") and it worked in every browser.

If you want a minimum of 4 characters, for instance,

System.out.println(String.format("%4d", 5));
// Results in "   5", minimum of 4 characters

In ES6 you can use Math.sign function to determine if,

1. its +ve no
2. its -ve no
3. its zero (0)
4. its NaN


console.log(Math.sign(1))        // prints 1 
console.log(Math.sign(-1))       // prints -1
console.log(Math.sign(0))        // prints 0
console.log(Math.sign("abcd"))   // prints NaN

In programming, a "magic number" is a value that should be given a symbolic name, but was instead slipped into the code as a literal, usually in more than one place.

It's bad for the same reason SPOT (Single Point of Truth) is good: If you wanted to change this constant later, you would have to hunt through your code to find every instance. It is also bad because it might not be clear to other programmers what this number represents, hence the "magic".

People sometimes take magic number elimination further, by moving these constants into separate files to act as configuration. This is sometimes helpful, but can also create more complexity than it's worth.

Code example:

HashMap<Integer,String> h = new HashMap<Integer,String> ();

h.put(null,null);
h.put(null, "a");

System.out.println(h);

Output:

{null=a}

It overrides the value at key null.

If you still don't know, you can get back the original object by:

alert($("#deviceTypeRoot")[0] == $("#deviceTypeRoot")[0]); //True
alert($("#deviceTypeRoot")[0] === $("#deviceTypeRoot")[0]);//True

because $("#deviceTypeRoot") also returns an array of objects which the selector has selected.

Edit

4+ years later after the original reply in 2015, virtualbox.org now offers an official user manual in both html and pdf formats, which effectively deprecates the previous version of this answer:

• Step 3 (Guest Additions) mentioned in this response as well as several others, is discussed in great detail in manual sections 4.1 and 4.2
• Step 1 (Shared Folders Setting in VirtualBox Manager) is discussed in section 4.3

Original Answer

Because there isn't an official answer yet and I literally just did this for my OS X/WinXP install, here's what I did:

1. VirtualBox Manager: Open the Shared Folders setting and click the '+' icon to add a new folder. Then, populate the Folder Path (or use the drop-down to navigate) with the folder you want shared and make sure "Auto-Mount" and "Make Permanent" are checked.
2. Boot Windows
3. Once Windows is running, goto the Devices menu (at the top of the VirtualBox Manager window) and select "Insert Guest Additions CD Image...". Cycle through the prompts and once you finish installing, let it reboot.
4. After Windows reboots, your new drive should show up as a Network Drive in Windows Explorer.

Hope that helps.

Aonepathan's one-liner was working for me until a recent typescript update.

I found Jecelyn Yeen's post which suggests posting this snippet into your TS Definition file

add file typings.d.ts to the project's root folder with below content

declare module "*.json" {
    const value: any;
    export default value;
}

and then import your data like this:

import * as data from './example.json';

update July 2019:

Typescript 2.9 (docs) introduced a better, smarter solution. Steps:

1. Add resolveJsonModule support with this line in your tsconfig.json file:

"compilerOptions": {
    ...
    "resolveJsonModule": true
  }

the import statement can now assumes a default export:

import data from './example.json';

and intellisense will now check the json file to see whether you can use Array etc. methods. pretty cool.

Just try noquote(a)

noquote("a")

[1] a

To access a single value you can use the method iat that is much faster than iloc:

df['Btime'].iat[0]

Output:

1.2

in my case i just changed spring.postgresql.jdbc.url that contained IPV4, i changed it to 127.0.0.1

It is a sort of format specifier for formatting numeric results. There are additional specifiers on the link.

What N does is that it separates numbers into thousand decimal places according to your CultureInfo and represents only 2 decimal digits in floating part as is N2 by rounding right-most digit if necessary.

N0 does not represent any decimal place but rounding is applied to it.

Let's exemplify.

using System;
using System.Globalization;


namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {
            double x = 567892.98789;
            CultureInfo someCulture = new CultureInfo("da-DK", false);

            // 10 means left-padded = right-alignment
            Console.WriteLine(String.Format(someCulture, "{0:N} denmark", x));
            Console.WriteLine("{0,10:N} us", x); 

            // watch out rounding 567,893
            Console.WriteLine(String.Format(someCulture, "{0,10:N0}", x)); 
            Console.WriteLine("{0,10:N0}", x);

            Console.WriteLine(String.Format(someCulture, "{0,10:N5}", x));
            Console.WriteLine("{0,10:N5}", x);


            Console.ReadKey();

        }
    }
}

It yields,

567.892,99 denmark
567,892.99 us
   567.893
   567,893
567.892,98789
567,892.98789

If you would like to purposely link your project A in Release against another project B in Debug, say to keep the overall performance benefits of your application while debugging, then you will likely hit this error. You can fix this by temporarily modifying the preprocessor flags of project B to disable iterator debugging (and make it match project A):

In Project B's "Debug" properties, Configuration Properties -> C/C++ -> Preprocessor, add the following to Preprocessor Definitions:

_HAS_ITERATOR_DEBUGGING=0;_ITERATOR_DEBUG_LEVEL=0;

Rebuild project B in Debug, then build project A in Release and it should link correctly.

In my opinion, the simplest way to get the amount of selected rows is the following:

The cursor object returns a list with the results when using the fetch commands (fetchall(), fetchone(), fetchmany()). To get the selected rows just print the length of this list. But it just makes sense for fetchall(). ;-)

Example:

print len(cursor.fetchall) 

The function for symfony 2.1 and newer, without any deprecated function:

/**
 * @param \Symfony\Component\Form\Form $form
 *
 * @return array
 */
private function getErrorMessages(\Symfony\Component\Form\Form $form)
{
    $errors = array();

    if ($form->count() > 0) {
        foreach ($form->all() as $child) {
            /**
             * @var \Symfony\Component\Form\Form $child
             */
            if (!$child->isValid()) {
                $errors[$child->getName()] = $this->getErrorMessages($child);
            }
        }
    } else {
        /**
         * @var \Symfony\Component\Form\FormError $error
         */
        foreach ($form->getErrors() as $key => $error) {
            $errors[] = $error->getMessage();
        }
    }

    return $errors;
}

DecimalFormat df=new DecimalFormat("0.00");

Use this code to get exact two decimal points. Even if the value is 0.0 it will give u 0.00 as output.

Instead if you use:

DecimalFormat df=new DecimalFormat("#.00");  

It wont convert 0.2659 into 0.27. You will get an answer like .27.

string[] abcd = obj.show(); 

Response.Write(string.join("</br>", abcd));

An iterative function to free your list:

void freeList(struct node* head)
{
   struct node* tmp;

   while (head != NULL)
    {
       tmp = head;
       head = head->next;
       free(tmp);
    }

}

What the function is doing is the follow:

1. check if head is NULL, if yes the list is empty and we just return

2. Save the head in a tmp variable, and make head point to the next node on your list (this is done in head = head->next

3. Now we can safely free(tmp) variable, and head just points to the rest of the list, go back to step 1

Step 1: Add the submodule

   git submodule add git://some_repository.git some_repository

Step 2: Fix the submodule to a particular commit

By default the new submodule will be tracking HEAD of the master branch, but it will NOT be updated as you update your primary repository. In order to change the submodule to track a particular commit or different branch, change directory to the submodule folder and switch branches just like you would in a normal repository.

   git checkout -b some_branch origin/some_branch

Now the submodule is fixed on the development branch instead of HEAD of master.

From Two Guys Arguing — Tie Git Submodules to a Particular Commit or Branch .

thelist.Max(e => e.age);

No, the problem is that * is a reserved character in regexes, so you need to escape it.

String [] separado = line.split("\\*");

* means "zero or more of the previous expression" (see the Pattern Javadocs), and you weren't giving it any previous expression, making your split expression illegal. This is why the error was a PatternSyntaxException.

If you have two []byte, compare them using bytes.Equal. The Golang documentation says:

Equal returns a boolean reporting whether a and b are the same length and contain the same bytes. A nil argument is equivalent to an empty slice.

Usage:

package main

import (
    "fmt"
    "bytes"
)

func main() {
    a := []byte {1,2,3}
    b := []byte {1,2,3}
    c := []byte {1,2,2}

    fmt.Println(bytes.Equal(a, b))
    fmt.Println(bytes.Equal(a, c))
}

This will print

true
false

As far as I know, there are three different ways.

Use \n in your print:

print("first line\nSecond line")

Use sep="\n" in print:

print("first line", "second line", sep="\n")

Use triple quotes and a multiline string:

print("""
Line1
Line2
""")

One more way assume branch1 - is branch with committed changes branch2 - is desirable branch

git fetch && git checkout branch1
git log

select commit ids that you need to move

git fetch && git checkout branch2
git cherry-pick commit_id_first..commit_id_last
git push

Now revert unpushed commits from initial branch

git fetch && git checkout branch1
git reset --soft HEAD~1

When moving classes into specific packages like repository, controller, domain just the generic @SpringBootApplication is not enough.

You will have to specify the base package for component scan

@ComponentScan("base_package")

For JPA

@EnableJpaRepositories(basePackages = "repository")

is also needed, so spring data will know where to look into for repository interfaces.

The power in dBm is the 10 times the logarithm of the ratio of actual Power/1 milliWatt.

dBm stands for "decibel milliwatts". It is a convenient way to measure power. The exact formula is

P(dBm) = 10 · log10( P(W) / 1mW ) 

where

P(dBm) = Power expressed in dBm   
P(W) = the absolute power measured in Watts   
mW = milliWatts   
log10 = log to base 10

From this formula, the power in dBm of 1 Watt is 30 dBm. Because the calculation is logarithmic, every increase of 3dBm is approximately equivalent to doubling the actual power of a signal.

There is a conversion calculator and a comparison table here. There is also a comparison table on the Wikipedia english page, but the value it gives for mobile networks is a bit off.

Your actual question was "does the - sign count?"

The answer is yes, it does.

-85 dBm is less powerful (smaller) than -60 dBm. To understand this, you need to look at negative numbers. Alternatively, think about your bank account. If you owe the bank 85 dollars/rands/euros/rupees (-85), you're poorer than if you only owe them 65 (-65), i.e. -85 is smaller than -65. Also, in temperature measurements, -85 is colder than -65 degrees.

Signal strengths for mobile networks are always negative dBm values, because the transmitted network is not strong enough to give positive dBm values.

How will this affect your location finding? I have no idea, because I don't know what technology you are using to estimate the location. The values you quoted correspond roughly to a 5 bar network in GSM, UMTS or LTE, so you shouldn't have be having any problems due to network strength.

I would go with this one (C#):

static long LCM(long[] numbers)
{
    return numbers.Aggregate(lcm);
}
static long lcm(long a, long b)
{
    return Math.Abs(a * b) / GCD(a, b);
}
static long GCD(long a, long b)
{
    return b == 0 ? a : GCD(b, a % b);
}

Just some clarifications, because at first glance it doesn't seams so clear what this code is doing:

Aggregate is a Linq Extension method, so you cant forget to add using System.Linq to your references.

Aggregate gets an accumulating function so we can make use of the property lcm(a,b,c) = lcm(a,lcm(b,c)) over an IEnumerable. More on Aggregate

GCD calculation makes use of the Euclidean algorithm.

lcm calculation uses Abs(a*b)/gcd(a,b) , refer to Reduction by the greatest common divisor.

Hope this helps,

In simpler words, you can understand Bootstrap as a front-end web framework that was created by Twitter for faster creation of device responsive web applications. Bootstrap can also be understood mostly as a collection of CSS classes that are defined in it which can simply be used directly. It makes use of CSS, javascript, jQuery etc. in the background to create the style, effects, and actions for Bootstrap elements.

You might know that we use CSS for styling webpage elements and create classes and assign classes to webpage elements to apply the style to them. Bootstrap here makes the designing simpler since we only have to include Bootstrap files and mention Bootstrap's predefined class names for our webpage elements and they will be styled automatically through Bootstrap. Through this, we get rid of writing our own CSS classes to style webpage elements. Most importantly Bootstrap is designed in such a way that makes your website device responsive and that is the main purpose of it. Other alternates for Bootstrap could be - Foundation, Materialize etc. frameworks.

Bootstrap makes you free from writing lots of CSS code and it also saves your time that you spend on designing the web pages.

Not sure exactly what your after, but I think I get it.

A header - stays at the top of the screen? A footer - stays at the bottom of the screen? Content area -> fits the space between the footer and the header?

You can do this by absolute positioning or with fixed positioning.

Here is an example with absolute positioning: http://jsfiddle.net/FMYXY/1/

Markup:

<div class="header">Header</div>
<div class="mainbody">Main Body</div>
<div class="footer">Footer</div>

CSS:

.header {outline:1px solid red; height: 40px; position:absolute; top:0px; width:100%;}
.mainbody {outline:1px solid green; min-height:200px; position:absolute; top:40px; width:100%; height:90%;}
.footer {outline:1px solid blue; height:20px; position:absolute; height:25px;bottom:0; width:100%; } 

To make it work best, I'd suggest using % instead of pixels, as you will run into problems with different screen/device sizes.

How I would do this:

// function you can use:
function getSecondPart(str) {
    return str.split('-')[1];
}
// use the function:
alert(getSecondPart("sometext-20202"));

Ant Runtime

Simply set includeantruntime="false":

<javac includeantruntime="false" ...>...</javac>

If you have to use the javac-task multiple times you might want to consider using PreSetDef to define your own javac-task that always sets includeantruntime="false".

Additional Details

From http://www.coderanch.com/t/503097/tools/warning-includeantruntime-was-not-set:

That's caused by a misfeature introduced in Ant 1.8. Just add an attribute of that name to the javac task, set it to false, and forget it ever happened.

From http://ant.apache.org/manual/Tasks/javac.html:

Whether to include the Ant run-time libraries in the classpath; defaults to yes, unless build.sysclasspath is set. It is usually best to set this to false so the script's behavior is not sensitive to the environment in which it is run.

This solution will work until CSS4 is globally supported by all browsers. When that day comes just use CSS4. but until then, this works for current browsers.

browser-util.js

export const isMobile = {
  android: () => navigator.userAgent.match(/Android/i),
  blackberry: () => navigator.userAgent.match(/BlackBerry/i),
  ios: () => navigator.userAgent.match(/iPhone|iPad|iPod/i),
  opera: () => navigator.userAgent.match(/Opera Mini/i),
  windows: () => navigator.userAgent.match(/IEMobile/i),
  any: () => (isMobile.android() || isMobile.blackberry() || 
  isMobile.ios() || isMobile.opera() || isMobile.windows())
};

onload:

old way:

isMobile.any() ? document.getElementsByTagName("body")[0].className += 'is-touch' : null;

newer way:

isMobile.any() ? document.body.classList.add('is-touch') : null;

The above code will add the "is-touch" class to the body tag if the device has a touch screen. Now any location in your web application where you would have css for :hover you can call body:not(.is-touch) the_rest_of_my_css:hover

for example:

button:hover

becomes:

body:not(.is-touch) button:hover

This solution avoids using modernizer as the modernizer lib is a very big library. If all you're trying to do is detect touch screens, This will be best when the size of the final compiled source is a requirement.

I think gradle 2.14.1 fixes the issue. The accepted answer is correct, but there is a bug in gradle with –refresh-dependencies. 2.14.1 fixes that.

See https://discuss.gradle.org/t/refresh-dependencies-should-use-cachechangingmodulesfor-0s/556

I use

file_age() {
    local filename=$1
    echo $(( $(date +%s) - $(date -r $filename +%s) ))
}

is_stale() {
    local filename=$1
    local max_minutes=20
    [ $(file_age $filename) -gt $(( $max_minutes*60 )) ]
}

if is_stale /my/file; then
    ...
fi

If you will convert the commandtext:

Private Function ConvToNonParm(ByRef Cmd As SqlClient.SqlCommand) As String
    For myCnt As Int16 = 1 To Cmd.Parameters.Count
        Dim myVal As String = Cmd.Parameters(myCnt - 1).Value
        Select Case Cmd.Parameters(myCnt - 1).SqlDbType
            Case SqlDbType.Char, SqlDbType.NChar, SqlDbType.VarChar, SqlDbType.NChar, SqlDbType.NVarChar 'and so on
                myVal = "'" & myVal & "'"
                'Case "others...."

            Case Else
                'please assing
        End Select
        Cmd.CommandText = Replace(Cmd.CommandText, Cmd.Parameters(myCnt - 1).ToString, myVal)
    Next
    Cmd.Parameters.Clear()
    Return Cmd.CommandText
End Function

Now you can get the non parameter commandtext as follows:

    myCmd.CommandText = "UPDATE someTable SET Value = @Value"
    myCmd.CommandText &= " WHERE Id = @Id"
    myCmd.Parameters.AddWithValue("@Id", 1234)
    myCmd.Parameters.AddWithValue("@Value", "myValue")

    myCmd.CommandText = ConvToNonParm(myCmd)

and the Result is "UPDATE someTable SET Value = 'myValue' WHERE Id = 1234" without parameter anymore

I was having this problem too. For me, I couldn't start/stop openfire (it said it was stopped, but everything was still running)

sudo /etc/init.d/openfire stop
sudo /etc/init.d/openfire start

Also, restarting apache did not help either

sudo /etc/init.d/apache2 restart

The errors were inside:

/opt/openfire/logs/stderror.log
Error creating server listener on port 5269: Address already in use
Error creating server listener on port 5222: Address already in use

The way I fixed this, I had to actually turn off the server inside the admin area for my host.

I don't think there's a standard.
Each web environment provides its own 'standard' for such things. Besides, the url is usually too short for anything (256 bytes limit on some browsers). Of course longer arrays/data can be send with POST requests.

However, there are some methods:

1. There's a PHP way, which uses square brackets ([,]) in URL queries. For example a query such as ?array_name[]=item&array_name[]=item_2 has been said to work, despite being poorly documented, with PHP automatically converting it into an array. Source: https://stackoverflow.com/a/9547490/3787376

2. Object data-interchange formats (e.g. JSON - official website, PHP documentation) can also be used if they have methods of converting variables to and from strings as JSON does.
   Also an url-encoder (available for most programming languages) is required for HTTP get requests to encode the string data correctly.

Although the "square brackets method" is simple and works, it is limited to PHP and arrays.
If other types of variable such as classes or passing variables within query strings in a language other than PHP is required, the JSON method is recommended.

Example in PHP of JSON method (method 2):

$myarray = array(2, 46, 34, "dfg");
$serialized = json_encode($myarray)
$data = 'myarray=' . rawurlencode($serialized);
// Send to page via cURL, header() or other service.

Code for receiving page (PHP):

$myarray = json_decode($_GET["myarray"]); // Or $_POST["myarray"] if a post request.

f is an (instance) method. However, you are calling it via fibo.f, where fibo is the class object. Hence, f is unbound (not bound to any class instance).

If you did

a = fibo()
a.f()

then that f is bound (to the instance a).

I know it is an old thread, but recently I needed the same and found a neat way:

SELECT c.name FROM pragma_table_info('your_table_name') c;

It is called the ternary operator. It is shorthand for an if-else block. See here for an example http://www.php.net/manual/en/language.operators.comparison.php#language.operators.comparison.ternary

Have you tried JQuery? Vanilla javascript can be tough. Try using this:

$('.container-element').add('<div>Insert Div Content</div>');

.container-element is a JQuery selector that marks the element with the class "container-element" (presumably the parent element in which you want to insert your divs). Then the add() function inserts HTML into the container-element.

That syntax should work OK, but you can try this alternative.

<a href="javascript:void(0);" onclick="ShowOld(2367,146986,2);">

or

<a href="javascript:ShowOld(2367, 146986, 2);">

UPDATED ANSWER FOR STRING VALUES

If you are passing strings, use single quotes for your function's parameters

<a href="javascript:ShowOld('foo', 146986, 'bar');">

For EditText in image above, You have to create two xml files in res-->drawable folder. First will be "bg_edittext_focused.xml" paste the lines of code in it

<?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android" >
        <solid android:color="#FFFFFF" />
        <stroke
            android:width="2dip"
            android:color="#F6F6F6" />
        <corners android:radius="2dip" />
        <padding
            android:bottom="7dip"
            android:left="7dip"
            android:right="7dip"
            android:top="7dip" />
    </shape>

Second file will be "bg_edittext_normal.xml" paste the lines of code in it

<?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android" >
        <solid android:color="#F6F6F6" />
        <stroke
            android:width="2dip"
            android:color="#F6F6F6" />
        <corners android:radius="2dip" />
        <padding
            android:bottom="7dip"
            android:left="7dip"
            android:right="7dip"
            android:top="7dip" />
    </shape>

In res-->drawable folder create another xml file with name "bg_edittext.xml" that will call above mentioned code. paste the following lines of code below in bg_edittext.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/bg_edittext_focused" android:state_focused="true"/>
    <item android:drawable="@drawable/bg_edittext_normal"/>
</selector>

Finally in res-->layout-->example.xml file in your case wherever you created your editText you'll call bg_edittext.xml as background

   <EditText
    :::::
    :::::  
    android:background="@drawable/bg_edittext"
    :::::
    :::::
    />

def multiples(n,m,starting_from=1,increment_by=1):
    """
    # Where n is the number 10 and m is the number 2 from your example. 
    # In case you want to print the multiples starting from some other number other than 1 then you could use the starting_from parameter
    # In case you want to print every 2nd multiple or every 3rd multiple you could change the increment_by 
    """
    print [ n*x for x in range(starting_from,m+1,increment_by) ] 

The currently accepted answer does not actually address the question, which asks how to save lists that contain both strings and float numbers. For completeness I provide a fully working example, which is based, with some modifications, on the link given in @joris comment.

import numpy as np

names  = np.array(['NAME_1', 'NAME_2', 'NAME_3'])
floats = np.array([ 0.1234 ,  0.5678 ,  0.9123 ])

ab = np.zeros(names.size, dtype=[('var1', 'U6'), ('var2', float)])
ab['var1'] = names
ab['var2'] = floats

np.savetxt('test.txt', ab, fmt="%10s %10.3f")

Update: This example also works properly in Python 3 by using the 'U6' Unicode string dtype, when creating the ab structured array, instead of the 'S6' byte string. The latter dtype would work in Python 2.7, but would write strings like b'NAME_1' in Python 3.

SELECT Code,Description FROM TABLE

-- This will Include only date part of 14th March 2010. Any date with date companents will not be considered.
WHERE ID= 1 AND FromDate >= CONVERT(DATETIME, '2010-02-14', 126) AND ToDate <= DATEADD(dd, 1, CONVERT(DATETIME, '2010-03-14', 126))

-- This will Include the whole day of 14th March 2010
--WHERE ID= 1 AND FromDate >= CONVERT(DATETIME, '2010-02-14', 126) AND ToDate < DATEADD(dd, 1, CONVERT(DATETIME, '2010-03-14', 126))

See this JSFiddle

 input[type="text"]_x000D_
    {_x000D_
        border: 0;_x000D_
        border-bottom: 1px solid red;_x000D_
        outline: 0;_x000D_
    }

<form>_x000D_
        <input type="text" value="See! ONLY BOTTOM BORDER!" />_x000D_
    </form>

You should always use $array[] if possible because as the box states there is no overhead for the function call. Thus it is a bit faster than the function call.

How do I call the function or what do I wrap it in so that if it takes longer than 5 seconds the script cancels it?

I posted a gist that solves this question/problem with a decorator and a threading.Timer. Here it is with a breakdown.

Imports and setups for compatibility

It was tested with Python 2 and 3. It should also work under Unix/Linux and Windows.

First the imports. These attempt to keep the code consistent regardless of the Python version:

from __future__ import print_function
import sys
import threading
from time import sleep
try:
    import thread
except ImportError:
    import _thread as thread

Use version independent code:

try:
    range, _print = xrange, print
    def print(*args, **kwargs): 
        flush = kwargs.pop('flush', False)
        _print(*args, **kwargs)
        if flush:
            kwargs.get('file', sys.stdout).flush()            
except NameError:
    pass

Now we have imported our functionality from the standard library.

exit_after decorator

Next we need a function to terminate the main() from the child thread:

def quit_function(fn_name):
    # print to stderr, unbuffered in Python 2.
    print('{0} took too long'.format(fn_name), file=sys.stderr)
    sys.stderr.flush() # Python 3 stderr is likely buffered.
    thread.interrupt_main() # raises KeyboardInterrupt

And here is the decorator itself:

def exit_after(s):
    '''
    use as decorator to exit process if 
    function takes longer than s seconds
    '''
    def outer(fn):
        def inner(*args, **kwargs):
            timer = threading.Timer(s, quit_function, args=[fn.__name__])
            timer.start()
            try:
                result = fn(*args, **kwargs)
            finally:
                timer.cancel()
            return result
        return inner
    return outer

Usage

And here's the usage that directly answers your question about exiting after 5 seconds!:

@exit_after(5)
def countdown(n):
    print('countdown started', flush=True)
    for i in range(n, -1, -1):
        print(i, end=', ', flush=True)
        sleep(1)
    print('countdown finished')

Demo:

>>> countdown(3)
countdown started
3, 2, 1, 0, countdown finished
>>> countdown(10)
countdown started
10, 9, 8, 7, 6, countdown took too long
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 11, in inner
  File "<stdin>", line 6, in countdown
KeyboardInterrupt

The second function call will not finish, instead the process should exit with a traceback!

KeyboardInterrupt does not always stop a sleeping thread

Note that sleep will not always be interrupted by a keyboard interrupt, on Python 2 on Windows, e.g.:

@exit_after(1)
def sleep10():
    sleep(10)
    print('slept 10 seconds')

>>> sleep10()
sleep10 took too long         # Note that it hangs here about 9 more seconds
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 11, in inner
  File "<stdin>", line 3, in sleep10
KeyboardInterrupt

nor is it likely to interrupt code running in extensions unless it explicitly checks for PyErr_CheckSignals(), see Cython, Python and KeyboardInterrupt ignored

I would avoid sleeping a thread more than a second, in any case - that's an eon in processor time.

How do I call the function or what do I wrap it in so that if it takes longer than 5 seconds the script cancels it and does something else?

To catch it and do something else, you can catch the KeyboardInterrupt.

>>> try:
...     countdown(10)
... except KeyboardInterrupt:
...     print('do something else')
... 
countdown started
10, 9, 8, 7, 6, countdown took too long
do something else

for /f "usebackq" %A in (`TYPE c:\temp\file.txt ^| find /v /c "" `) do set numlines=%A

in a batch file, use %%A instead of %A

With AWK you can do, I find it faster than sort

 ./yourscript.ksh | awk '!a[$0]++'

Here is simple Android Code for detecting gesture direction

In MainActivity.java and activity_main.xml, write the following code:

MainActivity.java

import java.util.ArrayList;

import android.app.Activity;
import android.gesture.Gesture;
import android.gesture.GestureLibraries;
import android.gesture.GestureLibrary;
import android.gesture.GestureOverlayView;
import android.gesture.GestureOverlayView.OnGesturePerformedListener;
import android.gesture.GestureStroke;
import android.gesture.Prediction;
import android.os.Bundle;
import android.widget.Toast;

public class MainActivity extends Activity implements
        OnGesturePerformedListener {

    GestureOverlayView gesture;
    GestureLibrary lib;
    ArrayList<Prediction> prediction;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        lib = GestureLibraries.fromRawResource(MainActivity.this,
                R.id.gestureOverlayView1);
        gesture = (GestureOverlayView) findViewById(R.id.gestureOverlayView1);
        gesture.addOnGesturePerformedListener(this);
    }

    @Override
    public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) {
        ArrayList<GestureStroke> strokeList = gesture.getStrokes();
        // prediction = lib.recognize(gesture);
        float f[] = strokeList.get(0).points;
        String str = "";

        if (f[0] < f[f.length - 2]) {
            str = "Right gesture";
        } else if (f[0] > f[f.length - 2]) {
            str = "Left gesture";
        } else {
            str = "no direction";
        }
        Toast.makeText(getApplicationContext(), str, Toast.LENGTH_LONG).show();

    }

}

My answer is quite easy:

Use Entity Framework for communication between C# and your SQL database. That will make parameterized SQL strings that isn't vulnerable to SQL injection.

As a bonus, it's very easy to work with as well.

Why flush if you can commit?

As someone new to working with databases and sqlalchemy, the previous answers - that flush() sends SQL statements to the DB and commit() persists them - were not clear to me. The definitions make sense but it isn't immediately clear from the definitions why you would use a flush instead of just committing.

Since a commit always flushes (https://docs.sqlalchemy.org/en/13/orm/session_basics.html#committing) these sound really similar. I think the big issue to highlight is that a flush is not permanent and can be undone, whereas a commit is permanent, in the sense that you can't ask the database to undo the last commit (I think)

@snapshoe highlights that if you want to query the database and get results that include newly added objects, you need to have flushed first (or committed, which will flush for you). Perhaps this is useful for some people although I'm not sure why you would want to flush rather than commit (other than the trivial answer that it can be undone).

In another example I was syncing documents between a local DB and a remote server, and if the user decided to cancel, all adds/updates/deletes should be undone (i.e. no partial sync, only a full sync). When updating a single document I've decided to simply delete the old row and add the updated version from the remote server. It turns out that due to the way sqlalchemy is written, order of operations when committing is not guaranteed. This resulted in adding a duplicate version (before attempting to delete the old one), which resulted in the DB failing a unique constraint. To get around this I used flush() so that order was maintained, but I could still undo if later the sync process failed.

See my post on this at: Is there any order for add versus delete when committing in sqlalchemy

Similarly, someone wanted to know whether add order is maintained when committing, i.e. if I add object1 then add object2, does object1 get added to the database before object2 Does SQLAlchemy save order when adding objects to session?

Again, here presumably the use of a flush() would ensure the desired behavior. So in summary, one use for flush is to provide order guarantees (I think), again while still allowing yourself an "undo" option that commit does not provide.

Autoflush and Autocommit

Note, autoflush can be used to ensure queries act on an updated database as sqlalchemy will flush before executing the query. https://docs.sqlalchemy.org/en/13/orm/session_api.html#sqlalchemy.orm.session.Session.params.autoflush

Autocommit is something else that I don't completely understand but it sounds like its use is discouraged: https://docs.sqlalchemy.org/en/13/orm/session_api.html#sqlalchemy.orm.session.Session.params.autocommit

Memory Usage

Now the original question actually wanted to know about the impact of flush vs. commit for memory purposes. As the ability to persist or not is something the database offers (I think), simply flushing should be sufficient to offload to the database - although committing shouldn't hurt (actually probably helps - see below) if you don't care about undoing.

sqlalchemy uses weak referencing for objects that have been flushed: https://docs.sqlalchemy.org/en/13/orm/session_state_management.html#session-referencing-behavior

This means if you don't have an object explicitly held onto somewhere, like in a list or dict, sqlalchemy won't keep it in memory.

However, then you have the database side of things to worry about. Presumably flushing without committing comes with some memory penalty to maintain the transaction. Again, I'm new to this but here's a link that seems to suggest exactly this: https://stackoverflow.com/a/15305650/764365

In other words, commits should reduce memory usage, although presumably there is a trade-off between memory and performance here. In other words, you probably don't want to commit every single database change, one at a time (for performance reasons), but waiting too long will increase memory usage.

If you don't want to recompile (as Visual Leak Detector requires) I would recommend WinDbg, which is both powerful and fast (though it's not as easy to use as one could desire).

On the other hand, if you don't want to mess with WinDbg, you can take a look at UMDH, which is also developed by Microsoft and it's easier to learn.

Take a look at these links in order to learn more about WinDbg, memory leaks and memory management in general:

• Memory Leak Detection Using Windbg
• Memory Leak Detection in MFC
• Common WinDbg Commands (Thematically Grouped)
• C/C++ Memory Corruption And Memory Leaks
• The Memory Management Reference
• Using LeakDiag to Debug Unmanaged Memory Leaks
• Heap: Pleasures and Pains

Your sprite is created mid way through the playerSprite function... it also goes out of scope and ceases to exist at the end of that same function. The sprite must be created where you can pass it to playerSprite to initialize it and also where you can pass it to your draw function.

Perhaps declare it above your first while?

Can you provide the code where you use this.props.history.push('/Page2');?

Have you tried the goBack() method?

this.props.history.goBack();

I found the reference in boot.ts wasn't the correct path. Updating that path to /// <reference path=">../../../node_modules/angular2/typings/browser.d.ts" /> resolved the Promise errors.

All of these are config settings. In my case I have two computers with everything in XAMPP synced. On the other computer phpMyAdmin did start normally. So the problem in my case seemed to be with the specific computer, not the config files. Stopping firewall didn't help.

Finally, more or less by accident, I bumped into the file:

...path_to_XAMPP\XAMPP...\mysql\bin\mysqld-debug.exe

Doubleclicking that file miraculously gave me back PhpMyAdmin. Posted here in case anyone might be helped by this too.

Ok, as this thread appears among the first results of google and for other users having the same question, you don't have to reivent the wheel as pointed by trueboroda there is the ng2-file-upload library which simplify this process of uploading a file with angular 6 and 7 all you need to do is:

Install the latest Angular CLI

yarn add global @angular/cli

Then install rx-compat for compatibility concern

npm install rxjs-compat --save

Install ng2-file-upload

npm install ng2-file-upload --save

Import FileSelectDirective Directive in your module.

import { FileSelectDirective } from 'ng2-file-upload';

Add it to [declarations] under @NgModule:
declarations: [ ... FileSelectDirective , ... ]

In your component

import { FileUploader } from 'ng2-file-upload/ng2-file-upload';
...

export class AppComponent implements OnInit {

   public uploader: FileUploader = new FileUploader({url: URL, itemAlias: 'photo'});
}

Template

<input type="file" name="photo" ng2FileSelect [uploader]="uploader" />

There is actually a clever way to do this that is useful for any list of tuples where the size of each tuple is 2: you can convert your list into a single dictionary.

For example,

test = [("hi", 1), ("there", 2)]
test = dict(test)
print test["hi"] # prints 1

You've probably miss-typed something above that bit of code or created your own class called IPAddress. If you're using the .net one, that function should be available.

Have you tried using System.Net.IPAddress just in case?

System.Net.IPAddress ipaddress = System.Net.IPAddress.Parse("127.0.0.1");  //127.0.0.1 as an example

The docs on Microsoft's site have a complete example which works fine on my machine.

Simply put, numpy.newaxis is used to increase the dimension of the existing array by one more dimension, when used once. Thus,

• 1D array will become 2D array

• 2D array will become 3D array

• 3D array will become 4D array

• 4D array will become 5D array

and so on..

Here is a visual illustration which depicts promotion of 1D array to 2D arrays.

Scenario-1: np.newaxis might come in handy when you want to explicitly convert a 1D array to either a row vector or a column vector, as depicted in the above picture.

Example:

# 1D array
In [7]: arr = np.arange(4)
In [8]: arr.shape
Out[8]: (4,)

# make it as row vector by inserting an axis along first dimension
In [9]: row_vec = arr[np.newaxis, :]     # arr[None, :]
In [10]: row_vec.shape
Out[10]: (1, 4)

# make it as column vector by inserting an axis along second dimension
In [11]: col_vec = arr[:, np.newaxis]     # arr[:, None]
In [12]: col_vec.shape
Out[12]: (4, 1)

Scenario-2: When we want to make use of numpy broadcasting as part of some operation, for instance while doing addition of some arrays.

Example:

Let's say you want to add the following two arrays:

 x1 = np.array([1, 2, 3, 4, 5])
 x2 = np.array([5, 4, 3])

If you try to add these just like that, NumPy will raise the following ValueError :

ValueError: operands could not be broadcast together with shapes (5,) (3,)

In this situation, you can use np.newaxis to increase the dimension of one of the arrays so that NumPy can broadcast.

In [2]: x1_new = x1[:, np.newaxis]    # x1[:, None]
# now, the shape of x1_new is (5, 1)
# array([[1],
#        [2],
#        [3],
#        [4],
#        [5]])

Now, add:

In [3]: x1_new + x2
Out[3]:
array([[ 6,  5,  4],
       [ 7,  6,  5],
       [ 8,  7,  6],
       [ 9,  8,  7],
       [10,  9,  8]])

Alternatively, you can also add new axis to the array x2:

In [6]: x2_new = x2[:, np.newaxis]    # x2[:, None]
In [7]: x2_new     # shape is (3, 1)
Out[7]: 
array([[5],
       [4],
       [3]])

Now, add:

In [8]: x1 + x2_new
Out[8]: 
array([[ 6,  7,  8,  9, 10],
       [ 5,  6,  7,  8,  9],
       [ 4,  5,  6,  7,  8]])

Note: Observe that we get the same result in both cases (but one being the transpose of the other).

Scenario-3: This is similar to scenario-1. But, you can use np.newaxis more than once to promote the array to higher dimensions. Such an operation is sometimes needed for higher order arrays (i.e. Tensors).

Example:

In [124]: arr = np.arange(5*5).reshape(5,5)

In [125]: arr.shape
Out[125]: (5, 5)

# promoting 2D array to a 5D array
In [126]: arr_5D = arr[np.newaxis, ..., np.newaxis, np.newaxis]    # arr[None, ..., None, None]

In [127]: arr_5D.shape
Out[127]: (1, 5, 5, 1, 1)

As an alternative, you can use numpy.expand_dims that has an intuitive axis kwarg.

# adding new axes at 1st, 4th, and last dimension of the resulting array
In [131]: newaxes = (0, 3, -1)
In [132]: arr_5D = np.expand_dims(arr, axis=newaxes)
In [133]: arr_5D.shape
Out[133]: (1, 5, 5, 1, 1)

More background on np.newaxis vs np.reshape

newaxis is also called as a pseudo-index that allows the temporary addition of an axis into a multiarray.

np.newaxis uses the slicing operator to recreate the array while numpy.reshape reshapes the array to the desired layout (assuming that the dimensions match; And this is must for a reshape to happen).

Example

In [13]: A = np.ones((3,4,5,6))
In [14]: B = np.ones((4,6))
In [15]: (A + B[:, np.newaxis, :]).shape     # B[:, None, :]
Out[15]: (3, 4, 5, 6)

In the above example, we inserted a temporary axis between the first and second axes of B (to use broadcasting). A missing axis is filled-in here using np.newaxis to make the broadcasting operation work.

General Tip: You can also use None in place of np.newaxis; These are in fact the same objects.

In [13]: np.newaxis is None
Out[13]: True

P.S. Also see this great answer: newaxis vs reshape to add dimensions

This way you get the intersection of two lists and also get the common duplicates.

>>> from collections import Counter
>>> a = Counter([1,2,3,4,5])
>>> b = Counter([1,3,5,6])
>>> a &= b
>>> list(a.elements())
[1, 3, 5]

Another approach would be to deserialize into a java.util.Map, and then just modify the Java Map as wanted. This separates the Java-side data handling from the data transport mechanism (JSON), which is how I prefer to organize my code: using JSON for data transport, not as a replacement data structure.

Try creating a method in your Activity something like...

public void setActivityBackgroundColor(int color) {
    View view = this.getWindow().getDecorView();
    view.setBackgroundColor(color);
}

Then call it from your OnClickListener passing in whatever colour you want.

Either use instanceof or method Class.isAssignableFrom(Class<?> cls).

In my case working with python 2.7 with numpy version 1.15.0, it worked with

pip install statsmodels=="0.10.0"

Try this:

delete from your_table;    
delete from sqlite_sequence where name='your_table';

SQLite Autoincrement

SQLite keeps track of the largest ROWID that a table has ever held using the special SQLITE_SEQUENCE table. The SQLITE_SEQUENCE table is created and initialized automatically whenever a normal table that contains an AUTOINCREMENT column is created. The content of the SQLITE_SEQUENCE table can be modified using ordinary UPDATE, INSERT, and DELETE statements. But making modifications to this table will likely perturb the AUTOINCREMENT key generation algorithm. Make sure you know what you are doing before you undertake such changes.

So that you don't mess up other permissions already on the file, use the flag +, such as via

Recently discovered that a third party library - Square Retrofit can do the job very well.

Defining REST endpoint

public interface GitHubService {
   @GET("/users/{user}/repos")
   List<Repo> listRepos(@Path("user") String user,Callback<List<User>> cb);
}

Getting the concrete service

RestAdapter restAdapter = new RestAdapter.Builder()
    .setEndpoint("https://api.github.com")
    .build();
GitHubService service = restAdapter.create(GitHubService.class);

Calling the REST endpoint

List<Repo> repos = service.listRepos("octocat",new Callback<List<User>>() { 
    @Override
    public void failure(final RetrofitError error) {
        android.util.Log.i("example", "Error, body: " + error.getBody().toString());
    }
    @Override
    public void success(List<User> users, Response response) {
        // Do something with the List of Users object returned
        // you may populate your adapter here
    }
});

The library handles the json serialization and deserailization for you. You may customize the serialization and deserialization too.

Gson gson = new GsonBuilder()
    .setFieldNamingPolicy(FieldNamingPolicy.LOWER_CASE_WITH_UNDERSCORES)
    .registerTypeAdapter(Date.class, new DateTypeAdapter())
    .create();

RestAdapter restAdapter = new RestAdapter.Builder()
    .setEndpoint("https://api.github.com")
    .setConverter(new GsonConverter(gson))
    .build();

As stated in the JQuery documentation

The focusout event is sent to an element when it, or any element inside of it, loses focus. This is distinct from the blur event in that it supports detecting the loss of focus on descendant elements (in other words, it supports event bubbling).

You could use a navigation property if its available. It produces an inner join in the SQL.

where s.ServiceAssignment.LocationId == 1

Move your row before <div class="container marketing"> and wrap it with a new container, because current container width is 1170px (not 100%):

<div class='hero'>
  <div class="row">
   ...
  </div>
</div>

CSS:

.hero {
  background-color: #2ba6cb;
  padding: 0 90px;
}

Just write:

private static double balance = 0;

and you could also write those like that:

private static int id = 0;
private static double annualInterestRate = 0;
public static java.util.Date dateCreated;

HTML Code :

<div class="ajax-loader">
  <img src="{{ url('guest/images/ajax-loader.gif') }}" class="img-responsive" />
</div>

CSS Code:

.ajax-loader {
  visibility: hidden;
  background-color: rgba(255,255,255,0.7);
  position: absolute;
  z-index: +100 !important;
  width: 100%;
  height:100%;
}

.ajax-loader img {
  position: relative;
  top:50%;
  left:50%;
}

JQUERY Code:

$.ajax({
  type:'POST',
  beforeSend: function(){
    $('.ajax-loader').css("visibility", "visible");
  },
  url:'/quantityPlus',
  data: {
   'productId':p1,
   'quantity':p2,
   'productPrice':p3},
   success:function(data){
     $('#'+p1+'value').text(data.newProductQuantity);
     $('#'+p1+'amount').text("? "+data.productAmount);
     $('#totalUnits').text(data.newNoOfUnits);
     $('#totalAmount').text("? "+data.newTotalAmount);
  },
  complete: function(){
    $('.ajax-loader').css("visibility", "hidden");
  }
});

}

Patrick's solution is probably the cleanest. If you need to dynamically pick up the module as well, you can import it like:

module = __import__('foo')
func = getattr(module, 'bar')
func()

AngularJS / UI-Bootstrap Answer

• Use Bootstrap's has-feedback class to show an icon inside the input field.
• Make sure the icon has style="cursor: pointer; pointer-events: all;"
• Use ng-click to clear the text.

JavaScript (app.js)

var app = angular.module('plunker', ['ui.bootstrap']);

app.controller('MainCtrl', function($scope) {

  $scope.params = {};

  $scope.clearText = function() {
    $scope.params.text = null;
  }

});

HTML (index.html snippet)

      <div class="form-group has-feedback">
        <label>text box</label>
        <input type="text"
               ng-model="params.text"
               class="form-control"
               placeholder="type something here...">
        <span ng-if="params.text"
              ng-click="clearText()"
              class="glyphicon glyphicon-remove form-control-feedback" 
              style="cursor: pointer; pointer-events: all;"
              uib-tooltip="clear">
        </span>
      </div>

Adding a solution which I've recently used myself and haven't seen mentioned here. If you have Apache Commons Collections available then you can use the SetUtils#difference method:

// Returns all the elements of test2 which are not in test1
SetUtils.difference(test2, test1) 

Note that according to the documentation the returned set is an unmodifiable view:

Returns a unmodifiable view containing the difference of the given Sets, denoted by a \ b (or a - b). The returned view contains all elements of a that are not a member of b.

Programmers may have questions about stack frames not in a broad term (that it is a singe entity in the stack that serves just one function call and keeps return address, arguments and local variables) but in a narrow sense – when the term stack frames is mentioned in context of compiler options.

Whether the author of the question has meant it or not, but the concept of a stack frame from the aspect of compiler options is a very important issue, not covered by the other replies here.

For example, Microsoft Visual Studio 2015 C/C++ compiler has the following option related to stack frames:

• /Oy (Frame-Pointer Omission)

GCC have the following:

• -fomit-frame-pointer (Don't keep the frame pointer in a register for functions that don't need one. This avoids the instructions to save, set up and restore frame pointers; it also makes an extra register available in many functions)

Intel C++ Compiler have the following:

• -fomit-frame-pointer (Determines whether EBP is used as a general-purpose register in optimizations)

which has the following alias:

• /Oy

Delphi has the following command-line option:

• -$W+ (Generate Stack Frames)

In that specific sense, from the compiler’s perspective, a stack frame is just the entry and exit code for the routine, that pushes an anchor to the stack – that can also be used for debugging and for exception handling. Debugging tools may scan the stack data and use these anchors for backtracing, while locating call sites in the stack, i.e. to display names of the functions in the order they have been called hierarchically. For Intel architecture, it is push ebp; mov ebp, esp or enter for entry and mov esp, ebp; pop ebp or leave for exit.

That’s why it is very important to understand for a programmer what a stack frame is in when it comes to compiler options – because the compiler can control whether to generate this code or not.

In some cases, the stack frame (entry and exit code for the routine) can be omitted by the compiler, and the variables will directly be accessed via the stack pointer (SP/ESP/RSP) rather than the convenient base pointer (BP/ESP/RSP). Conditions for omission of the stack frame, for example:

• the function is a leaf function (i.e. an end-entity that doesn’t call other functions);
• there are no try/finally or try/except or similar constructs, i.e. no exceptions are used;
• no routines are called with outgoing parameters on the stack;
• the function has no parameters;
• the function has no inline assembly code;
• etc...

Omitting stack frames (entry and exit code for the routine) can make code smaller and faster, but it may also negatively affect the debuggers’ ability to backtrace the data in the stack and to display it to the programmer. These are the compiler options that determine under which conditions a function should have the entry and exit code, for example: (a) always, (b) never, (c) when needed (specifying the conditions).

I assume that the main idea is to find if number is negative and display it in correct format.

For those who use PHP5.3 might be interested in using Number Formatter Class - http://php.net/manual/en/class.numberformatter.php. This function, as well as range of other useful things, can format your number.

$profitLoss = 25000 - 55000;

$a= new \NumberFormatter("en-UK", \NumberFormatter::CURRENCY); 
$a->formatCurrency($profitLoss, 'EUR');
// would display (€30,000.00)

Here also a reference to why brackets are used for negative numbers: http://www.open.edu/openlearn/money-management/introduction-bookkeeping-and-accounting/content-section-1.7

I suggest that someone needs to make empty plot in order to add some graphics on it later. So, using

plot(1, type="n", xlab="", ylab="", xlim=c(0, 10), ylim=c(0, 10))

you can specify the axes limits of your graphic.

URL Specifies the URL of the document to embed in the iframe. Possible values:

An absolute URL - points to another web site (like src="http://www.example.com/default.htm") A relative URL - points to a file within a web site (like src="default.htm")

So, if you were looking for command arguments, take a look at Tim's answer. If you just want to read a line from console:

#include <stdio.h>

int main()
{
  char string [256];
  printf ("Insert your full address: ");
  gets (string);
  printf ("Your address is: %s\n",string);
  return 0;
}

Yes, it is not secure, you can do buffer overrun, it does not check for end of file, it does not support encodings and a lot of other stuff. Actually I didn't even think whether it did ANY of this stuff. I agree I kinda screwed up :) But...when I see a question like "How to read a line from the console in C?", I assume a person needs something simple, like gets() and not 100 lines of code like above. Actually, I think, if you try to write those 100 lines of code in reality, you would do many more mistakes, than you would have done had you chosen gets ;)

I'm not sure it's worth it for me to type this all up from scratch since this article published in A List Apart does a pretty good job explaining it. MDN also has a handy guide for HTML5 forms and validation (covering the API and also the related CSS).

The other answers so far have a lot of technical information. I will try to answer, as requested, in simple terms.

Serialization is what you do to an instance of an object if you want to dump it to a raw buffer, save it to disk, transport it in a binary stream (e.g., sending an object over a network socket), or otherwise create a serialized binary representation of an object. (For more info on serialization see Java Serialization on Wikipedia).

If you have no intention of serializing your class, you can add the annotation just above your class @SuppressWarnings("serial").

If you are going to serialize, then you have a host of things to worry about all centered around the proper use of UUID. Basically, the UUID is a way to "version" an object you would serialize so that whatever process is de-serializing knows that it's de-serializing properly. I would look at Ensure proper version control for serialized objects for more information.

The second question is actually easier to answer. Look at the stringWithContentsOfURL:encoding:error: method of NSString - it lets you pass in a URL as an instance of NSURL (which can easily be instantiated from NSString) and returns a string with the complete contents of the page at that URL. For example:

NSString *googleString = @"http://www.google.com";
NSURL *googleURL = [NSURL URLWithString:googleString];
NSError *error;
NSString *googlePage = [NSString stringWithContentsOfURL:googleURL 
                                                encoding:NSASCIIStringEncoding
                                                   error:&error];

After running this code, googlePage will contain the HTML for www.google.com, and error will contain any errors encountered in the fetch. (You should check the contents of error after the fetch.)

Going the other way (from a UIWebView) is a bit trickier, but is basically the same concept. You'll have to pull the request from the view, then do the fetch as before:

NSURL *requestURL = [[yourWebView request] URL];
NSError *error;
NSString *page = [NSString stringWithContentsOfURL:requestURL 
                                          encoding:NSASCIIStringEncoding
                                             error:&error];

EDIT: Both these methods take a performance hit, however, since they do the request twice. You can get around this by grabbing the content from a currently-loaded UIWebView using its stringByEvaluatingJavascriptFromString: method, as such:

NSString *html = [yourWebView stringByEvaluatingJavaScriptFromString: 
                                         @"document.body.innerHTML"];

This will grab the current HTML contents of the view using the Document Object Model, parse the JavaScript, then give it to you as an NSString* of HTML.

Another way is to do your request programmatically first, then load the UIWebView from what you requested. Let's say you take the second example above, where you have NSString *page as the result of a call to stringWithContentsOfURL:encoding:error:. You can then push that string into the web view using loadHTMLString:baseURL:, assuming you also held on to the NSURL you requested:

[yourWebView loadHTMLString:page baseURL:requestURL];

I'm not sure, however, if this will run JavaScript found in the page you load (the method name, loadHTMLString, is somewhat ambiguous, and the docs don't say much about it).

For more info:

• UIWebView class reference
• NSString class reference
• NSURL class reference

Firstly: The >>> code you see in python examples is a way to indicate that it is Python code. It's used to separate Python code from output. Like this:

>>> 4+5
9

Here we see that the line that starts with >>> is the Python code, and 9 is what it results in. This is exactly how it looks if you start a Python interpreter, which is why it's done like that.

You never enter the >>> part into a .py file.

That takes care of your syntax error.

Secondly, ctypes is just one of several ways of wrapping Python libraries. Other ways are SWIG, which will look at your Python library and generate a Python C extension module that exposes the C API. Another way is to use Cython.

They all have benefits and drawbacks.

SWIG will only expose your C API to Python. That means you don't get any objects or anything, you'll have to make a separate Python file doing that. It is however common to have a module called say "wowza" and a SWIG module called "_wowza" that is the wrapper around the C API. This is a nice and easy way of doing things.

Cython generates a C-Extension file. It has the benefit that all of the Python code you write is made into C, so the objects you write are also in C, which can be a performance improvement. But you'll have to learn how it interfaces with C so it's a little bit extra work to learn how to use it.

ctypes have the benefit that there is no C-code to compile, so it's very nice to use for wrapping standard libraries written by someone else, and already exists in binary versions for Windows and OS X.

Almost all answers I searched for this issue say that Python on Windows comes with tkinter and tcl already installed, and I had no luck trying to download or install them using pip, or actviestate.com site. I eventually found that when I was installing python using the binary installer, I had unchecked the module related to TCL and tkinter. So, I ran the binary installer again and chose to modify my python version by this time selecting this option. No need to do anything manually then. If you go to your python terminal, then the following commands should show you version of tkinter installed with your Python:

import tkinter
import _tkinter
tkinter._test()

I've written up a long answer to this question, but it covers repositories that are accessed via ssh key access, not https with meta tags. It covers both packages and modules. It also mentions how to use branches other than master.

When you use a Range object, you cannot simply use the following syntax:

Dim myRange as Range
myRange = Range("A1")  

You must use the set keyword to assign Range objects:

Function getData(currentWorksheet As Worksheet, dataStartRow As Integer, dataEndRow As Integer, DataStartCol As Integer, dataEndCol As Integer)

    Dim dataTable As Range
    Set dataTable = currentWorksheet.Range(currentWorksheet.Cells(dataStartRow, DataStartCol), currentWorksheet.Cells(dataEndRow, dataEndCol))

    Set getData = dataTable

End Function

Sub main()
    Dim test As Range

    Set test = getData(ActiveSheet, 1, 3, 2, 5)
    test.select

End Sub

Note that every time a range is declared I use the Set keyword.

You can also allow your getData function to return a Range object instead of a Variant although this is unrelated to the problem you are having.

    .....
    textElement = findViewById(R.id.textElement);
    gestureDetectorCompat = new GestureDetectorCompat(this, new MyGesture());
    textElement.setOnTouchListener(onTouchListener);

}

 View.OnTouchListener onTouchListener = new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        gestureDetectorCompat.onTouchEvent(event);
        return true;
    }
};
    class MyGesture extends GestureDetector.SimpleOnGestureListener {

        return true;

}

I recommend to use the Using jquery validation plugin and jquery ui date picker

jQuery.validator.addMethod("customDateValidator", function(value, element) {
// dd-mm-yyyy
   var re = /^([0]?[1-9]|[1|2][0-9]|[3][0|1])[./-]([0]?[1-9]|[1][0-2])[./-]([0-9]{4}|[0-9]{2})$/ ; 
   if (! re.test(value) ) return false
   // parseDate throws exception if the value is invalid
   try{jQuery.datepicker.parseDate( 'dd-mm-yy', value);return true ;}
   catch(e){return false;} 
   },
   "Please enter a valid date format dd-mm-yyyy"
);

this.ui.form.validate({
    debug: true,
    rules : {
    title : { required : true, minlength: 4 }, 
    date : { required: true, customDateValidator: true }
    }
}) ;

Using Jquery and date picker just create a function with

// dd-mm-yyyy
var re = /^([0]?[1-9]|[1|2][0-9]|[3][0|1])[./-]([0]?[1-9]|[1][0-2])[./-]([0-9]{4}|[0-9]{2})$/ ; 
 if (! re.test(value) ) return false
// parseDate throws exception if the value is invalid
try{jQuery.datepicker.parseDate( 'dd-mm-yy', value);return true ;}
catch(e){return false;}

You might use only the regular expression for validation

// dd-mm-yyyy
var re = /^([0]?[1-9]|[1|2][0-9]|[3][0|1])[./-]([0]?[1-9]|[1][0-2])[./-]([0-9]{4}|[0-9]{2})$/ ; 
return re.test(value) 

Of course the date format should be of your region

This will delete the local branches for which the remote tracking branches have been pruned. (Make sure you are on master branch!)

git checkout master
git branch -vv | grep ': gone]' | awk '{print $1}' | xargs git branch -d

Details:

• git branch -vv displays "gone" for local branches that the remote has been pruned.

  mybranch abc1234 [origin/mybranch: gone] commit comments
  

• -d will check if it has been merged (-D will delete it regardless)

  error: The branch 'mybranch' is not fully merged.
  

You can do it this way using INSTR:

SELECT * FROM users WHERE INSTR(LOWER(last_name), 'z') > 0;

INSTR returns zero if the substring is not in the string.

Out of interest, why don't you want to use like?

Edit: I took the liberty of making the search case insensitive so you don't miss Bob Zebidee. :-)

Your strcpy line attempts to store 9 bytes, not 8, because of the NUL terminator. It invokes undefined behaviour.

The call to free may or may not crash. The memory "after" the 4 bytes of your allocation might be used for something else by your C or C++ implementation. If it is used for something else, then scribbling all over it will cause that "something else" to go wrong, but if it isn't used for anything else, then you could happen to get away with it. "Getting away with it" might sound good, but is actually bad, since it means your code will appear to run OK, but on a future run you might not get away with it.

With a debugging-style memory allocator, you might find that a special guard value has been written there, and that free checks for that value and panics if it doesn't find it.

Otherwise, you might find that the next 5 bytes includes part of a link node belonging to some other block of memory which hasn't been allocated yet. Freeing your block could well involved adding it to a list of available blocks, and because you've scribbled in the list node, that operation could dereference a pointer with an invalid value, causing a crash.

It all depends on the memory allocator - different implementations use different mechanisms.

You can use word-wrap to break words or a continuous string of characters if it doesn't fit on a line in a container.

word-wrap: break-word;

this will keep breaking lines at appropriate break points unless a single string of characters doesn't fit on a line, in that case it will break.

JSFiddle

You could set your _JAVA_OPTIONS environmental variable. For example in bash this would do the trick:

export _JAVA_OPTIONS=-Djava.io.tmpdir=/new/tmp/dir

I put that into my bash login script and it seems to do the trick.

I had an old Excel database with "human-readable" dates, like 2010.03.28 20:12:30 Theese dates were in UTC+1 (CET) and needed to convert it to epoch time.

I used the =(A4-DATE(1970;1;1))*86400-3600 formula to convert the dates to epoch time from the A column to B column values. Check your timezone offset and make a math with it. 1 hour is 3600 seconds.

The only thing why i write here an anwser, you can see that this topic is more than 5 years old is that i use the new Excel versions and also red posts in this topic, but they're incorrect. The DATE(1970;1;1). Here the 1970 and the January needs to be separated with ; and not with ,

If you're also experiencing this issue, hope it helps you. Have a nice day :)

Multiple ways you could do this, but the easiest one which I use is:

For Launch Icons I use the flutter library Flutter Launcher Icon

For the Custom Splash Screen I create different Screen resolutions and then add the splash images in the mipmap folder as per the resolution for Android.

The last part is adjusting the launch_background.xml in the drawable folder in res folder in Android.

Just change your code to look like below:

<?xml version="1.0" encoding="utf-8"?>
<!-- Modify this file to customize your launch splash screen -->
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- <item android:drawable="@android:color/white" />
    <item android:drawable="@drawable/<splashfilename>" />     --> -->

    <!-- You can insert your own image assets here -->
    <item>
        <bitmap
            android:gravity="center"
            android:src="@mipmap/<Your splash image name here as per the mipmap folder>"/>
    </item>
</layer-list>

Few devs I have seen add the splash as drawable, I tried this but somehow the build fails in Flutter 1.0.0 and Dart SDK 2.0+. Therefore I prefer to add the splash in bitmap section.

iOS Splash-screen creation is rather simpler.

In the Runner folder in iOS just update the LaunchImage.png files with your custom Splash screen images with same names as LaunchImage.png @2x, @3x, @4x.

Just an addition I feel its good to have a 4x image as well in the LaunchImage.imageset. Just update your code in Content.json with following lines, below 3x scale to add a 4x scale option:

{
      "idiom" : "universal",
      "filename" : "[email protected]",
      "scale" : "4x"
    }

If you want unified way to handle both uncaught errors and unhandled promise rejections you may have a look on uncaught library.

EDIT

<script type="text/javascript" src=".../uncaught/lib/index.js"></script>

<script type="text/javascript">
    uncaught.start();
    uncaught.addListener(function (error) {
        console.log('Uncaught error or rejection: ', error.message);
    });
</script>

It listens window.unhandledrejection in addition to window.onerror.

val.ToString("".PadLeft(length, '0'))

in PHP-Fusion Open Source CMS, http://www.php-fusion.co.uk, we do it this way at core -

    <?php
        ob_start();
        // Your PHP codes here            
        ?>
        YOUR HTML HERE


        <?php 
        $html_output = ob_get_contents();
        ob_end_clean();
        echo $html_output;
    ?>

You won't be able to see anything loading one by one. The only loader will be your browser tab spinner, and it just displays everything in an instant after everything is loaded. Give it a try.

This method is fully compliant in html files.

They are called ifdef or include guards.

If writing a small program it might seems that it is not needed, but as the project grows you could intentionally or unintentionally include one file many times, which can result in compilation warning like variable already declared.

#ifndef checks whether HEADERFILE_H is not declared.
#define will declare HEADERFILE_H once #ifndef generates true.
#endif is to know the scope of #ifndef i.e end of #ifndef

If it is not declared which means #ifndef generates true then only the part between #ifndef and #endif executed otherwise not. This will prevent from again declaring the identifiers, enums, structure, etc...

Table with rounded corners and with bordered cells. Using @Ramon Tayag solution.

The key is to use border-spacing: 0 as he points out.

Solution using SCSS.

$line: 1px solid #979797;
$radius: 5px;

table {
  border: $line;
  border-radius: $radius;
  border-spacing: 0;
  th,
  tr:not(:last-child) td {
    border-bottom: $line;
  }
  th:not(:last-child),
  td:not(:last-child) {
    border-right: $line;
  }
}

Let's go back to the old school of batch programing on windows

net start | find "Service Name"

This will work everywhere...

In my search for a creating a v4 uuid, I came first to this page, then found this on http://php.net/manual/en/function.com-create-guid.php

function guidv4()
{
    if (function_exists('com_create_guid') === true)
        return trim(com_create_guid(), '{}');

    $data = openssl_random_pseudo_bytes(16);
    $data[6] = chr(ord($data[6]) & 0x0f | 0x40); // set version to 0100
    $data[8] = chr(ord($data[8]) & 0x3f | 0x80); // set bits 6-7 to 10
    return vsprintf('%s%s-%s-%s-%s-%s%s%s', str_split(bin2hex($data), 4));
}

credit: pavel.volyntsev

Edit: to clarify, this function will always give you a v4 uuid (PHP >= 5.3.0).

When the com_create_guid function is available (usually only on Windows), it will use that and strip the curly braces.

If not present (Linux), it will fall back on this strong random openssl_random_pseudo_bytes function, it will then uses vsprintf to format it into v4 uuid.

Two main purposes for error handling:

1. Trap errors you can predict but can't control the user from doing (e.g. saving a file to a thumb drive when the thumb drives has been removed)
2. For unexpected errors, present user with a form that informs them what the problem is. That way, they can relay that message to you and you might be able to give them a work-around while you work on a fix.

So, how would you do this?

First of all, create an error form to display when an unexpected error occurs.

It could look something like this (FYI: Mine is called frmErrors):

Notice the following labels:

• lblHeadline
• lblSource
• lblProblem
• lblResponse

Also, the standard command buttons:

• Ignore
• Retry
• Cancel

There's nothing spectacular in the code for this form:

Option Explicit

Private Sub cmdCancel_Click()
  Me.Tag = CMD_CANCEL
  Me.Hide
End Sub

Private Sub cmdIgnore_Click()
  Me.Tag = CMD_IGNORE
  Me.Hide
End Sub

Private Sub cmdRetry_Click()
  Me.Tag = CMD_RETRY
  Me.Hide
End Sub

Private Sub UserForm_Initialize()
  Me.lblErrorTitle.Caption = "Custom Error Title Caption String"
End Sub

Private Sub UserForm_QueryClose(Cancel As Integer, CloseMode As Integer)
  'Prevent user from closing with the Close box in the title bar.
    If CloseMode <> 1 Then
      cmdCancel_Click
    End If
End Sub

Basically, you want to know which button the user pressed when the form closes.

Next, create an Error Handler Module that will be used throughout your VBA app:

End Function

You may have errors that will be custom only to your application. This would typically be a short list of errors specifically only to your application. If you don't already have a constants module, create one that will contain an ENUM of your custom errors. (NOTE: Office '97 does NOT support ENUMS.). The ENUM should look something like this:

Public Enum CustomErrorName
  MaskedFilterNotSupported
  InvalidMonthNumber
End Enum

Create a module that will throw your custom errors.

namedtuple

is one of the easiest ways to clean up your code and make it more readable. It self-documents what is happening in the tuple. Namedtuples instances are just as memory efficient as regular tuples as they do not have per-instance dictionaries, making them faster than dictionaries.

from collections import namedtuple

Color = namedtuple('Color', ['hue', 'saturation', 'luminosity'])

 p = Color(170, 0.1, 0.6)
 if p.saturation >= 0.5:
     print "Whew, that is bright!"
 if p.luminosity >= 0.5:
     print "Wow, that is light"

Without naming each element in the tuple, it would read like this:

p = (170, 0.1, 0.6)
if p[1] >= 0.5:
    print "Whew, that is bright!"
if p[2]>= 0.5:
   print "Wow, that is light"

It is so much harder to understand what is going on in the first example. With a namedtuple, each field has a name. And you access it by name rather than position or index. Instead of p[1], we can call it p.saturation. It's easier to understand. And it looks cleaner.

Creating an instance of the namedtuple is easier than creating a dictionary.

# dictionary
>>>p = dict(hue = 170, saturation = 0.1, luminosity = 0.6)
>>>p['hue']
170

#nametuple
>>>from collections import namedtuple
>>>Color = namedtuple('Color', ['hue', 'saturation', 'luminosity'])
>>>p = Color(170, 0.1, 0.6)
>>>p.hue
170

When might you use namedtuple

1. As just stated, the namedtuple makes understanding tuples much easier. So if you need to reference the items in the tuple, then creating them as namedtuples just makes sense.
2. Besides being more lightweight than a dictionary, namedtuple also keeps the order unlike the dictionary.
3. As in the example above, it is simpler to create an instance of namedtuple than dictionary. And referencing the item in the named tuple looks cleaner than a dictionary. p.hue rather than p['hue'].

The syntax

collections.namedtuple(typename, field_names[, verbose=False][, rename=False])

• namedtuple is in the collections library.
• typename: This is the name of the new tuple subclass.
• field_names: A sequence of names for each field. It can be a sequence as in a list ['x', 'y', 'z'] or string x y z (without commas, just whitespace) or x, y, z.
• rename: If rename is True, invalid fieldnames are automatically replaced with positional names. For example, ['abc', 'def', 'ghi','abc'] is converted to ['abc', '_1', 'ghi', '_3'], eliminating the keyword 'def' (since that is a reserved word for defining functions) and the duplicate fieldname 'abc'.
• verbose: If verbose is True, the class definition is printed just before being built.

You can still access namedtuples by their position, if you so choose. p[1] == p.saturation. It still unpacks like a regular tuple.

Methods

All the regular tuple methods are supported. Ex: min(), max(), len(), in, not in, concatenation (+), index, slice, etc. And there are a few additional ones for namedtuple. Note: these all start with an underscore. _replace, _make, _asdict.

_replace Returns a new instance of the named tuple replacing specified fields with new values.

The syntax

somenamedtuple._replace(kwargs)

Example

>>>from collections import namedtuple

>>>Color = namedtuple('Color', ['hue', 'saturation', 'luminosity'])
>>>p = Color(170, 0.1, 0.6)

>>>p._replace(hue=87)
Color(87, 0.1, 0.6)

>>>p._replace(hue=87, saturation=0.2)
Color(87, 0.2, 0.6)

Notice: The field names are not in quotes; they are keywords here. Remember: Tuples are immutable - even if they are namedtuples and have the _replace method. The _replace produces a new instance; it does not modify the original or replace the old value. You can of course save the new result to the variable. p = p._replace(hue=169)

_make

Makes a new instance from an existing sequence or iterable.

The syntax

somenamedtuple._make(iterable)

Example

 >>>data = (170, 0.1, 0.6)
 >>>Color._make(data)
Color(hue=170, saturation=0.1, luminosity=0.6)

>>>Color._make([170, 0.1, 0.6])  #the list is an iterable
Color(hue=170, saturation=0.1, luminosity=0.6)

>>>Color._make((170, 0.1, 0.6))  #the tuple is an iterable
Color(hue=170, saturation=0.1, luminosity=0.6)

>>>Color._make(170, 0.1, 0.6) 
Traceback (most recent call last):
    File "<stdin>", line 1, in <module>
    File "<string>", line 15, in _make
TypeError: 'float' object is not callable

What happened with the last one? The item inside the parenthesis should be the iterable. So a list or tuple inside the parenthesis works, but the sequence of values without enclosing as an iterable returns an error.

_asdict

Returns a new OrderedDict which maps field names to their corresponding values.

The syntax

somenamedtuple._asdict()

Example

 >>>p._asdict()
OrderedDict([('hue', 169), ('saturation', 0.1), ('luminosity', 0.6)])

Reference: https://www.reddit.com/r/Python/comments/38ee9d/intro_to_namedtuple/

There is also named list which is similar to named tuple but mutable https://pypi.python.org/pypi/namedlist

Method

$user = $stmt->fetch(PDO::FETCH_ASSOC);

returns a dictionary. You can simply get email and password:

$email = $user['email'];
$password = $user['password'];

Other method

$users = $stmt->fetchall(PDO::FETCH_ASSOC);

returns a list of a dictionary

As lenik mentioned there are open-source libraries that already help with obtaining some data from GPlay. If you want to build one yourself you can try to parse the Google Play App page, but you should pay attention to the following:

• Make sure the URL you are trying to parse is not blocked in robots.txt - e.g. https://play.google.com/robots.txt
• Make sure that you are not doing it too often, Google will throttle and potentially blacklist you if you are doing it too much.
• Send a correct User-Agent header to actually show you are a bot
• The page of an app is big - make sure you accept gzip and request the mobile version
• GPlay website is not an API, it doesn't care that you parse it so it will change over time. Make sure you handle changes - e.g. by having test to make sure you get what you expected.

So that in mind getting one page metadata is a matter of fetching the page html and parsing it properly. With JSoup you can try:

      HttpClient httpClient = HttpClientBuilder.create().build();
      HttpGet request = new HttpGet(crawlUrl);
      HttpResponse rsp = httpClient.execute(request);

      int statusCode = rsp.getStatusLine().getStatusCode();

      if (statusCode == 200) {
           String content = EntityUtils.toString(rsp.getEntity());    
           Document doc = Jsoup.parse(content);
           //parse content, whatever you need
           Element price = doc.select("[itemprop=price]").first();
      }      

For that very simple use case that should get you started. However, the moment you want to do more interesting stuff, things get complicated:

• Search is forbidden in robots.
• Keeping app metadata up-to-date is hard to do. There are more than 2.2m apps, if you want to refresh their metadata daily there are 2.2 requests/day, which will 1) get blocked immediately, 2) costs a lot of money - pessimistic 220gb data transfer per day if one app is 100k
• How do you discover new apps
• How do you get pricing in each country, translations of each language

The list goes on. If you don't want to do all this by yourself, you can consider 42matters API, which supports lookup and search, top google charts, advanced queries and filters. And this for 35 languages and more than 50 countries.

Render props is most accurate approach to this problem. Instead of passing the child component to parent component as children props, let parent render child component manually. Render is built-in props in react, which takes function parameter. In this function you can let parent component render whatever you want with custom parameters. Basically it does the same thing as child props but it is more customizable.

class Child extends React.Component {
  render() {
    return <div className="Child">
      Child
      <p onClick={this.props.doSomething}>Click me</p>
           {this.props.a}
    </div>;
  }
}

class Parent extends React.Component {
  doSomething(){
   alert("Parent talks"); 
  }

  render() {
    return <div className="Parent">
      Parent
      {this.props.render({
        anythingToPassChildren:1, 
        doSomething: this.doSomething})}
    </div>;
  }
}

class Application extends React.Component {
  render() {
    return <div>
      <Parent render={
          props => <Child {...props} />
        }/>
    </div>;
  }
}

1. Extract the zip file into a folder, e.g. C:\Program Files\Java\ and it will create a jdk-11 folder (where the bin folder is a direct sub-folder). You may need Administrator privileges to extract the zip file to this location.

2. Set a PATH:

   • Select Control Panel and then System.
   • Click Advanced and then Environment Variables.
   • Add the location of the bin folder of the JDK installation to the PATH variable in System Variables.
   • The following is a typical value for the PATH variable: C:\WINDOWS\system32;C:\WINDOWS;"C:\Program Files\Java\jdk-11\bin"

3. Set JAVA_HOME:

   • Under System Variables, click New.
   • Enter the variable name as JAVA_HOME.
   • Enter the variable value as the installation path of the JDK (without the bin sub-folder).
   • Click OK.
   • Click Apply Changes.
4. Configure the JDK in your IDE (e.g. IntelliJ or Eclipse).

You are set.

To see if it worked, open up the Command Prompt and type java -version and see if it prints your newly installed JDK.

If you want to uninstall - just undo the above steps.

Note: You can also point JAVA_HOME to the folder of your JDK installations and then set the PATH variable to %JAVA_HOME%\bin. So when you want to change the JDK you change only the JAVA_HOME variable and leave PATH as it is.

You could have simply used Range("x1").value(11) something like below:

Sheets("Output").Range("$A$1:$A$500").value(11) =  Sheets(sheet_).Range("$A$1:$A$500").value(11)

range has default property "Value" plus value can have 3 optional orguments 10,11,12. 11 is what you need to tansfer both value and formats. It doesn't use clipboard so it is faster.- Durgesh

"Sencha way" for interacting with server data is setting up an Ext.data.Store proxied by a Ext.data.proxy.Proxy (in this case Ext.data.proxy.Ajax) furnished with a Ext.data.reader.Json (for JSON-encoded data, there are other readers available as well). For writing data back to the server there's a Ext.data.writer.Writers of several kinds.

Here's an example of a setup like that:

    var store = Ext.create('Ext.data.Store', {
        fields: [
            'counter_name',
            'counter_type',
            'counter_unit'
        ],

        proxy: {
            type: 'ajax',
            url: 'data1.json',

            reader: {
                type: 'json',
                idProperty: 'counter_name',
                rootProperty: 'counters'
            }
        }
    });

data1.json in this example (also available in this fiddle) contains your data verbatim. idProperty: 'counter_name' is probably optional in this case but usually points at primary key attribute. rootProperty: 'counters' specifies which property contains array of data items.

With a store setup this way you can re-read data from the server by calling store.load(). You can also wire the store to any Sencha Touch appropriate UI components like grids, lists or forms.

CSS add your code

.select_join option{

}

Ordinarily, floats aren't counted in the layout of their parents.

To prevent that, add overflow: hidden to the parent.

Bogosort twice and compare results (just to be sure it is sorted) if not do it again

Is better to relay in requestAnimationFrame than in a setTimeout. this is my solution in es6 modules and using Promises.

es6, modules and promises:

// onElementReady.js
const onElementReady = $element => (
  new Promise((resolve) => {
    const waitForElement = () => {
      if ($element) {
        resolve($element);
      } else {
        window.requestAnimationFrame(waitForElement);
      }
    };
    waitForElement();
  })
);

export default onElementReady;

// in your app
import onElementReady from './onElementReady';

const $someElement = document.querySelector('.some-className');
onElementReady($someElement)
  .then(() => {
    // your element is ready
  }

plain js and promises:

var onElementReady = function($element) {
  return new Promise((resolve) => {
    var waitForElement = function() {
      if ($element) {
        resolve($element);
      } else {
        window.requestAnimationFrame(waitForElement);
      }
    };
    waitForElement();
  })
};

var $someElement = document.querySelector('.some-className');
onElementReady($someElement)
  .then(() => {
    // your element is ready
  });

For anyone who came here trying find out how to set connection string dinamicaly, and got trouble with the solutions above (like "Format of the initialization string does not conform to specification starting at index 0.") when setting up the connection string in the constructor. This is how to fix it:

public static string ConnectionString
{
    get {
        if (ConfigurationManager.AppSettings["DevelopmentEnvironment"] == "true")
            return ConfigurationManager.ConnectionStrings["LocalDb"].ConnectionString;
        else
            return ConfigurationManager.ConnectionStrings["ExternalDb"].ConnectionString;
    }
}

public ApplicationDbContext() : base(ConnectionString)
{
}

How do I find a repository (if any) that contains this artifact?

Unfortunately due the binary license there is no public repository with the Oracle Driver JAR. This happens with many dependencies but is not Maven's fault. If you happen to find a public repository containing the JAR you can be sure that is illegal.

How do I add it so that Maven will use it?

Some JARs that can't be added due to license reasons have a pom entry in the Maven Central repo. Just check it out, it contains the vendor's preferred Maven info:

<groupId>com.oracle</groupId>
<artifactId>ojdbc14</artifactId>
<version>10.2.0.3.0</version>

...and the URL to download the file which in this case is http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html.

Once you've downloaded the JAR just add it to your computer repository with (note I pulled the groupId, artifactId and version from the POM):

mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc14 \
     -Dversion=10.2.0.3.0 -Dpackaging=jar -Dfile=ojdbc.jar -DgeneratePom=true

The last parameter for generating a POM will save you from pom.xml warnings

If your team has a local Maven repository this guide might be helpful to upload the JAR there.

I'm using nodejs client for access to private data

The solution was add the promp property with value consent to the settings object in oAuth2Client.generateAuthUrl function. Here is my code:

const getNewToken = (oAuth2Client, callback) => {
    const authUrl = oAuth2Client.generateAuthUrl({
        access_type: 'offline',
        prompt: 'consent',
        scope: SCOPES,
    })
    console.log('Authorize this app by visiting this url:', authUrl)
    const rl = readline.createInterface({
        input: process.stdin,
        output: process.stdout,
    })
    rl.question('Enter the code from that page here: ', (code) => {
        rl.close()
        oAuth2Client.getToken(code, (err, token) => {
            if (err) return console.error('Error while trying to retrieve access token', err)
            oAuth2Client.setCredentials(token)
            // Store the token to disk for later program executions
            fs.writeFile(TOKEN_PATH, JSON.stringify(token), (err) => {
                if (err) return console.error(err)
                console.log('Token stored to', TOKEN_PATH)
            })
            callback(oAuth2Client)
        })
    })
}

You can use the online parameters extractor to get the code for generate your token:

I hope the information is useful

you can use if() in place of decode() in mySql as follows This query will print all even id row.

mysql> select id, name from employee where id in
-> (select if(id%2=0,id,null) from employee);

came up across this one, on an existing account with private key I copied manually from elsewhere. so the error is because the public key is missing

so simply generate one from private

I have been reviewing the source code of Entity Framework and found a way to actually update an entity if you know the Key property:

public void Update<T>(T item) where T: Entity
{
    // assume Entity base class have an Id property for all items
    var entity = _collection.Find(item.Id);
    if (entity == null)
    {
        return;
    }

    _context.Entry(entity).CurrentValues.SetValues(item);
}

Otherwise, check the AddOrUpdate implementation for ideas.

Hope this help!

At my end, this happened when I had multiple collections with FetchType.EAGER, like this:

@ManyToMany(fetch = FetchType.EAGER, targetEntity = className.class)
@JoinColumn(name = "myClass_id")
@JsonView(SerializationView.Summary.class)
private Collection<Model> ModelObjects;

Additionally, the collections were joining on the same column.

To solve this issue, I changed one of the collections to FetchType.LAZY since it was okay for my use-case.

Goodluck! ~J

Java's String implements hashCode like this:

public int hashCode()

Returns a hash code for this string. The hash code for a String object is computed as

     s[0]*31^(n-1) + s[1]*31^(n-2) + ... + s[n-1]

using int arithmetic, where s[i] is the ith character of the string, n is the length of the string, and ^ indicates exponentiation. (The hash value of the empty string is zero.) 

So something like this:

int HashTable::hash (string word) {
    int result = 0;
    for(size_t i = 0; i < word.length(); ++i) {
        result += word[i] * pow(31, i);
    }
    return result;
}

I ran into the same issue and found another way to do this. It worked for in my case as it was a relatively small application.

First, the user will a click button in the component which needs to be printed. This will set a flag that can be accessed by the app component. Like so

.html file

<button mat-button (click)="printMode()">Print Preview</button>

.ts file

  printMode() {
    this.utilities.printMode = true;
  }

In the html of the app component, we hide everything except the router-outlet. Something like below

<div class="container">       
  <app-header *ngIf="!utilities.printMode"></app-header>
  <mat-sidenav-container>
    <mat-sidenav *ngIf="=!utilities.printMode">
      <app-sidebar></app-sidebar>
    </mat-sidenav>
    <mat-sidenav-content>
      <router-outlet></router-outlet>
    </mat-sidenav-content>
  </mat-sidenav-container>
</div>

With similar ngIf conidtions, we can also adjust the html template of the component to only show or hide things in printMode. So that the user will see only what needs to get printed when print preview is clicked.

We can now simply print or go back to normal mode with the below code

.html file

<button mat-button class="doNotPrint" (click)="print()">Print</button>
<button mat-button class="doNotPrint" (click)="endPrint()">Close</button>

.ts file

  print() {
    window.print();
  }

  endPrint() {
    this.utilities.printMode = false;
  } 

.css file (so that the print and close button's don't get printed)

@media print{
   .doNotPrint{display:none !important;}
 }

To solve this without jQuery .each() you'd have to fix your code like this:

var listItems = $("#productList").find("li");
var ind, len, product;

for ( ind = 0, len = listItems.length; ind < len; ind++ ) {
    product = $(listItems[ind]);

    // ...
}

Bugs in your original code:

1. for ... in will also loop through all inherited properties; i.e. you will also get a list of all functions that are defined by jQuery.

2. The loop variable li is not the list item, but the index to the list item. In that case the index is a normal array index (i.e. an integer)

Basically you are save to use .each() as it is more comfortable, but espacially when you are looping bigger arrays the code in this answer will be much faster.

For other alternatives to .each() you can check out this performance comparison: http://jsperf.com/browser-diet-jquery-each-vs-for-loop

Opacity changes the context of your z-index, as does the static positioning. Either add opacity to the element that doesn't have it or remove it from the element that does. You'll also have to either make both elements static positioned or specify relative or absolute position. Here's some background on contexts: http://philipwalton.com/articles/what-no-one-told-you-about-z-index/

There isn’t an easy way to control the formatting Excel applies when opening a .csv file. However listed below are three approaches that might help.

My preference is the first option.

Option 1 – Change the data in the file

You could change the data in the .csv file as follows ...,=”005”,... This will be displayed in Excel as ...,005,...

Excel will have kept the data as a formula, but copying the column and using paste special values will get rid of the formula but retain the formatting

Option 2 – Format the data

If it is simply a format issue and all your data in that column has a three digits length. Then open the data in Excel and then format the column containing the data with this custom format 000

Option 3 – Change the file extension to .dif (Data interchange format)

Change the file extension and use the file import wizard to control the formats. Files with a .dif extension are automatically opened by Excel when double clicked on.

Step by step:

• Change the file extension from .csv to .dif
• Double click on the file to open it in Excel.
• The 'File Import Wizard' will be launched.
• Set the 'File type' to 'Delimited' and click on the 'Next' button.
• Under Delimiters, tick 'Comma' and click on the 'Next' button.
• Click on each column of your data that is displayed and select a 'Column data format'. The column with the value '005' should be formatted as 'Text'.
• Click on the finish button, the file will be opened by Excel with the formats that you have specified.

Try this.

EditText text = (EditText)findViewById(R.id.edittext1);
String  str = text.getText().toString().trim();

As other people have answered, you need to do;

myDropDown.Items.Remove(ListItem li);

but if you want the page to refresh asynchronously, the dropdown needs to be inside an asp:UpdatePanel

after you do the Remove call, you need to call:

yourPanel.Update();

I know that this is old, but I've found that (while using Pillow) opening the file by using open(fp, 'w') and then saving the file will work. E.g:

with open(fp, 'w') as f:
    result.save(f)

fp being the file path, of course.
