The spread operator spread the Array into the separate arguments of a function.

let iterableObjB = [1,2,3,4]
function (...iterableObjB)  //turned into
function (1,2,3,4)

I am not going to attempt to refine the answers already given. Instead I will tell you about the way my own OOP PHP framework handles translations.

Internally, my framework use codes like en, fr, es, cn and so on. An array holds the languages supported by the website: array('en','fr','es','cn') The language code is passed via $_GET (lang=fr) and if not passed or not valid, it is set to the first language in the array. So at any time during program execution and from the very beginning, the current language is known.

It is useful to understand the kind of content that needs to be translated in a typical application:

1) error messages from classes (or procedural code) 2) non-error messages from classes (or procedural code) 3) page content (usually store in a database) 4) site-wide strings (like website name) 5) script-specific strings

The first type is simple to understand. Basically, we are talking about messages like "could not connect to the database ...". These messages only need to be loaded when an error occurs. My manager class receives a call from the other classes and using the information passed as parameters simply goes to relevant the class folder and retrieves the error file.

The second type of error message is more like the messages you get when the validation of a form went wrong. ("You cannot leave ... blank" or "please choose a password with more than 5 characters"). The strings need to be loaded before the class runs.I know what is

For the actual page content, I use one table per language, each table prefixed by the code for the language. So en_content is the table with English language content, es_content is for spain, cn_content for China and fr_content is the French stuff.

The fourth kind of string is relevant throughout your website. This is loaded via a configuration file named using the code for the language, that is en_lang.php, es_lang.php and so on. In the global language file you will need to load the translated languages such as array('English','Chinese', 'Spanish','French') in the English global file and array('Anglais','Chinois', 'Espagnol', 'Francais') in the French file. So when you populate a dropdown for language selection, it is in the correct language ;)

Finally you have the script-specific strings. So if you write a cooking application, it might be "Your oven was not hot enough".

In my application cycle, the global language file is loaded first. In there you will find not just global strings (like "Jack's Website") but also settings for some of the classes. Basically anything that is language or culture-dependent. Some of the strings in there include masks for dates (MMDDYYYY or DDMMYYYY), or ISO Language Codes. In the main language file, I include strings for individual classes becaue there are so few of them.

The second and last language file that is read from disk is the script language file. lang_en_home_welcome.php is the language file for the home/welcome script. A script is defined by a mode (home) and an action (welcome). Each script has its own folder with config and lang files.

The script pulls the content from the database naming the content table as explained above.

If something goes wrong, the manager knows where to get the language-dependent error file. That file is only loaded in case of an error.

So the conclusion is obvious. Think about the translation issues before you start developing an application or framework. You also need a development workflow that incorporates translations. With my framework, I develop the whole site in English and then translate all the relevant files.

Just a quick final word on the way the translation strings are implemented. My framework has a single global, the $manager, which runs services available to any other service. So for example the form service gets hold of the html service and uses it to write the html. One of the services on my system is the translator service. $translator->set($service,$code,$string) sets a string for the current language. The language file is a list of such statements. $translator->get($service,$code) retrieves a translation string. The $code can be numeric like 1 or a string like 'no_connection'. There can be no clash between services because each has its own namespace in the translator's data area.

I post this here in the hope it will save somebody the task of reinventing the wheel like I had to do a few long years ago.

Try:

System.IO.Directory.Delete(path,true)

This will recursively delete all files and folders underneath "path" assuming you have the permissions to do so.

In case you are using the annotation method for filter definition (as opposed to defining them in the web.xml), you can do so by just putting an array of mappings in the @WebFilter annotation:

/**
 * Filter implementation class LoginFilter
 */
@WebFilter(urlPatterns = { "/faces/Html/Employee","/faces/Html/Admin", "/faces/Html/Supervisor"})
public class LoginFilter implements Filter {
    ...

And just as an FYI, this same thing works for servlets using the servlet annotation too:

/**
 * Servlet implementation class LoginServlet
 */
@WebServlet({"/faces/Html/Employee", "/faces/Html/Admin", "/faces/Html/Supervisor"})
public class LoginServlet extends HttpServlet {
    ...

I've had very good experience with copy-maven-plugin. It has a much more convenient and concise syntax in comparison to maven-resources-plugin.

You can use // instead of single /. That converts to int directly.

If you write down a fractional value like 1 / 7 as decimal value you get

1/7 = 0.142857142857142857142857142857142857142857...

with an infinite sequence of 142857. Since you can only write a finite number of digits you will inevitably introduce a rounding (or truncation) error.

Numbers like 1/10 or 1/100 expressed as binary numbers with a fractional part also have an infinite number of digits after the decimal point:

1/10 = binary 0.0001100110011001100110011001100110...

Doubles store values as binary and therefore might introduce an error solely by converting a decimal number to a binary number, without even doing any arithmetic.

Decimal numbers (like BigDecimal), on the other hand, store each decimal digit as is (binary coded, but each decimal on its own). This means that a decimal type is not more precise than a binary floating point or fixed point type in a general sense (i.e. it cannot store 1/7 without loss of precision), but it is more accurate for numbers that have a finite number of decimal digits as is often the case for money calculations.

Java's BigDecimal has the additional advantage that it can have an arbitrary (but finite) number of digits on both sides of the decimal point, limited only by the available memory.

jPlayer is a free and open source HTML5 Audio and Video library that you may find useful. It has support for playlists built in: http://jplayer.org/

Calling conventions have nothing to do with the C/C++ programming languages and are rather specifics on how a compiler implements the given language. If you consistently use the same compiler, you never need to worry about calling conventions.

However, sometimes we want binary code compiled by different compilers to inter-operate correctly. When we do so we need to define something called the Application Binary Interface (ABI). The ABI defines how the compiler converts the C/C++ source into machine-code. This will include calling conventions, name mangling, and v-table layout. cdelc and stdcall are two different calling conventions commonly used on x86 platforms.

By placing the information on the calling convention into the source header, the compiler will know what code needs to be generated to inter-operate correctly with the given executable.

If you use MIUI ROM

Go to the developer option and in that disable MIUI optimization.You will be asked to reboot your phone. Reboot it and then run the app.

Starting from iOS 7, the system always returns the value 02:00:00:00:00:00 when you ask for the MAC address on any device.

In iOS 7 and later, if you ask for the MAC address of an iOS device, the system returns the value 02:00:00:00:00:00. If you need to identify the device, use the identifierForVendor property of UIDevice instead. (Apps that need an identifier for their own advertising purposes should consider using the advertisingIdentifier property of ASIdentifierManager instead.)"

Using Private API you can get user phone number on the following way:

extern NSString* CTSettingCopyMyPhoneNumber();


+(NSString *) phoneNumber {
NSString *phone = CTSettingCopyMyPhoneNumber();

return phone;
}

Also include CoreTelephony.framework to your project.

This is a small fix for mattmac's answer:

preg_replace('/\s+?(\S+)?$/', '', substr($string . ' ', 0, 201));

The only difference is to add a space at the end of $string. This ensures the last word isn't cut off as per ReX357's comment.

I don't have enough rep points to add this as a comment.

Notification.Builder API 11 or NotificationCompat.Builder API 1

This is a usage example.

Intent notificationIntent = new Intent(ctx, YourClass.class);
PendingIntent contentIntent = PendingIntent.getActivity(ctx,
        YOUR_PI_REQ_CODE, notificationIntent,
        PendingIntent.FLAG_CANCEL_CURRENT);

NotificationManager nm = (NotificationManager) ctx
        .getSystemService(Context.NOTIFICATION_SERVICE);

Resources res = ctx.getResources();
Notification.Builder builder = new Notification.Builder(ctx);

builder.setContentIntent(contentIntent)
            .setSmallIcon(R.drawable.some_img)
            .setLargeIcon(BitmapFactory.decodeResource(res, R.drawable.some_big_img))
            .setTicker(res.getString(R.string.your_ticker))
            .setWhen(System.currentTimeMillis())
            .setAutoCancel(true)
            .setContentTitle(res.getString(R.string.your_notif_title))
            .setContentText(res.getString(R.string.your_notif_text));
Notification n = builder.build();

nm.notify(YOUR_NOTIF_ID, n);

Your use-case isn't clear. However, if you are certain that you need this to be based on the DOM, and not model-data, then this is a way for one directive to have a reference to all elements with another directive specified on them.

The way is that the child directive can require the parent directive. The parent directive can expose a method that allows direct directive to register their element with the parent directive. Through this, the parent directive can access the child element(s). So if you have a template like:

<div parent-directive>
  <div child-directive></div>
  <div child-directive></div>
</div>

Then the directives can be coded like:

app.directive('parentDirective', function($window) {
  return {
    controller: function($scope) {
      var registeredElements = [];
      this.registerElement = function(childElement) {
        registeredElements.push(childElement);
      }
    }
  };
});

app.directive('childDirective', function() {
  return {
    require: '^parentDirective',
    template: '<span>Child directive</span>',
    link: function link(scope, iElement, iAttrs, parentController) {
      parentController.registerElement(iElement);
    }
   };
});

Recent protocols prefer usage of RFC3339 per golang time package documentation.

In general RFC1123Z should be used instead of RFC1123 for servers that insist on that format, and RFC3339 should be preferred for new protocols. RFC822, RFC822Z, RFC1123, and RFC1123Z are useful for formatting; when used with time.Parse they do not accept all the time formats permitted by the RFCs.

cutOffTime, _ := time.Parse(time.RFC3339, "2017-08-30T13:35:00Z")
// POSTDATE is a date time field in DB (datastore)
query := datastore.NewQuery("db").Filter("POSTDATE >=", cutOffTime).

Use String.Replace() if you just want to replace the dots from string. Alternative would be to use Pattern-Matcher with StringBuilder, this gives you more flexibility as you can find groups that are between dots. If using the latter, i would recommend that you ignore empty entries with "\\.+".

public static int count(String str, String regex) {
    int i = 0;
    Pattern p = Pattern.compile(regex);
    Matcher m = p.matcher(str);
    while (m.find()) {
        m.group();
        i++;
    }
    return i;
}

public static void main(String[] args) {
    int i = 0, j = 0, k = 0;
    String str = "-.-..-...-.-.--..-k....k...k..k.k-.-";

    // this will just remove dots
    System.out.println(str.replaceAll("\\.", ""));
    // this will just remove sequences of ".." dots
    System.out.println(str.replaceAll("\\.{2}", ""));
    // this will just remove sequences of dots, and gets
    // multiple of dots as 1
    System.out.println(str.replaceAll("\\.+", ""));

    /* for this to be more obvious, consider following */
    System.out.println(count(str, "\\."));
    System.out.println(count(str, "\\.{2}"));
    System.out.println(count(str, "\\.+"));
}

The output will be:

--------kkkkk--
-.--.-.-.---kk.kk.k-.-
--------kkkkk--

In a Firebird database the AFTER myOtherColumn does not work but you can try re-positioning the column using:

ALTER TABLE name ALTER column POSITION new_position

I guess it may work in other cases as well.

I'd give all the responses here a try first. But I wanted to just throw in what I do, just in case these do not work for you.

I've tried to solve the same problem you're having before, and in the end, what I decided on doing is to have only one JRE installed on my system at a given time. I do have about 10 different JDKs (1.3 through 1.6, and from various vendors - Sun, Oracle, IBM), since I do need it for development, but only one standalone JRE.

This has worked for me on my Windows 2000 + IE 6 computer at home, as well as my Windows XP + Multiple IE computer at work.

After multiple tests, this is the best way I found :)

Set<User> test = httpService.get(url).toResponseSet(User[].class);

All you need there

public <T> Set<T> toResponseSet(Class<T[]> setType) {
    HttpEntity<?> body = new HttpEntity<>(objectBody, headers);
    ResponseEntity<T[]> response = template.exchange(url, method, body, setType);
    return Sets.newHashSet(response.getBody());
}

If the DataGridView is bound to any datasource, you'll have to set the DataGridView's DataSource property to Nothing.

If the DataGridView is not bound to any data source, this code will do the trick:

    if ($(el).val() == '') $(el).attr('type', 'text');
    $(el).focus(function() {
        $(el).attr('type', type);
        el.click();
    });
    $(el).blur(function() {
        if ($(el).val() == '') $(el).attr('type', 'text');
    });
});

a % b

in c++ default:

(-7/3) => -2
-2 * 3 => -6
so a%b => -1

(7/-3) => -2
-2 * -3 => 6
so a%b => 1

in python:

-7 % 3 => 2
7 % -3 => -2

in c++ to python:

(b + (a%b)) % b

The easiest way without fiddling with command line:

1. launch Xcode once.
2. run ios simulator
3. drag the ios simulator icon to dock it.

Next time you want to use it, just click on the ios simulator icon in the dock.

Expanding on @ybo's answer - it isn't possible because the instance you have of the base class isn't actually an instance of the derived class. It only knows about the members of the base class, and doesn't know anything about those of the derived class.

The reason that you can cast an instance of the derived class to an instance of the base class is because the derived class actually already is an instance of the base class, since it has those members already. The opposite cannot be said.

Assuming that your search is stylus photo 2100. Try the following example is using RLIKE.

SELECT * FROM `buckets` WHERE `bucketname` RLIKE REPLACE('stylus photo 2100', ' ', '+.*');

EDIT

Another way is to use FULLTEXT index on bucketname and MATCH ... AGAINST syntax in your SELECT statement. So to re-write the above example...

SELECT * FROM `buckets` WHERE MATCH(`bucketname`) AGAINST (REPLACE('stylus photo 2100', ' ', ','));

I recently wrote on this topic, though this post it old, I thought it will be helpful to someone who wants to know how to implement BaseAdapter.notifyDataSetChanged() step by step and in a correct way.

Please follow How to correctly implement BaseAdapter.notifyDataSetChanged() in Android or the newer blog BaseAdapter.notifyDataSetChanged().

If you want a proper button then you'll need some javascript. Something like this (needs some work on the styling but you get the gist). Wouldn't bother using jquery for something so trivial to be honest.

<html>
<head>
<style type="text/css">
.on { 
border:1px outset;
color:#369;
background:#efefef; 
}

.off {
border:1px outset;
color:#369;
background:#f9d543; 
}
</style>

<script language="javascript">
function togglestyle(el){
    if(el.className == "on") {
        el.className="off";
    } else {
        el.className="on";
    }
}
</script>

</head>

<body>
<input type="button" id="btn" value="button" class="off" onclick="togglestyle(this)" />

This took me a while to figure out, as the conventional window['someFunctionName']() did not work for me at first. The names of my functions were being pulled as an AJAX response from a database. Also, for whatever reason, my functions were declared outside of the scope of the window, so in order to fix this I had to rewrite the functions I was calling from

function someFunctionName() {}

to

window.someFunctionName = function() {}

and from there I could call window['someFunctionName']() with ease. I hope this helps someone!

With help from numpy one can calculate for example a linear fitting.

# plot the data itself
pylab.plot(x,y,'o')

# calc the trendline
z = numpy.polyfit(x, y, 1)
p = numpy.poly1d(z)
pylab.plot(x,p(x),"r--")
# the line equation:
print "y=%.6fx+(%.6f)"%(z[0],z[1])

var stringExample = "firstName:name1, lastName:last1 | firstName:name2, lastName:last2";    

var initial_arr_objects = stringExample.split("|");
    var objects =[];
    initial_arr_objects.map((e) => {
          var string = e;
          var fields = string.split(','),fieldObject = {};
        if( typeof fields === 'object') {
           fields.forEach(function(field) {
              var c = field.split(':');
              fieldObject[c[0]] = c[1]; //use parseInt if integer wanted
           });
        }
            console.log(fieldObject)
            objects.push(fieldObject);
        });

"objects" array will have all the objects

You could also use the EPEL-repository, and then do sudo yum install python26 to install python 2.6

Your version does not support that character set, I believe it was 5.5.3 that introduced it. You should upgrade your mysql to the version you used to export this file.

The error is then quite clear: you set a certain character set in your code, but your mysql version does not support it, and therefore does not know about it.

According to https://dev.mysql.com/doc/refman/5.5/en/charset-unicode-utf8mb4.html :

utf8mb4 is a superset of utf8

so maybe there is a chance you can just make it utf8, close your eyes and hope, but that would depend on your data, and I'd not recommend it.

This has served me well for a while now. It prints error or warning messages in red, one line per parameter, and allows an optional exit code.

    printf '%s\n' "$@" >&2

    test -t 1 && tput sgr0 # Reset terminal
    true
}

error()
{
    # Output error messages with optional exit code
    # @param $1...: Messages
    # @param $N: Exit code (optional)

    messages=( "$@" )

    # If the last parameter is a number, it's not part of the messages
    last_parameter="${messages[@]: -1}"
    if [[ "$last_parameter" =~ ^[0-9]*$ ]]
    then
        exit_code=$last_parameter
        unset messages[$((${#messages[@]} - 1))]
    fi

    warning "${messages[@]}"

    exit ${exit_code:-$EX_UNKNOWN}

You can use the variables name itself to check if a value is an integer. for example:

#include <iostream>
using namespace std;

int main (){

int firstvariable;
int secondvariable;
float float1;
float float2;

cout << "Please enter two integers and then press Enter:" << endl;
cin >> firstvariable;
cin >> secondvariable;

if(firstvariable && secondvariable){
    cout << "Time for some simple mathematical operations:\n" << endl;

    cout << "The sum:\n " << firstvariable << "+" << secondvariable 
    <<"="<< firstvariable + secondvariable << "\n " << endl;
}else{
    cout << "\n[ERROR\tINVALID INPUT]\n"; 
    return 1; 
} 
return 0;    
}

For AWS users.

I had to use the following steps to get there.

1) Ensure that pip and django are installed at the sudo level

• sudo apt-get install python-pip
• sudo pip install django

2) Ensure that security group in-bound rules includ http on port 80 for 0.0.0.0/0

• configured through AWS console

3) Add Public IP and DNS to ALLOWED_HOSTS

• ALLOWED_HOSTS is a list object that you can find in settings.py
• ALLOWED_HOSTS = ["75.254.65.19","ec2-54-528-27-21.compute-1.amazonaws.com"]

4) Launch development server with sudo on port 80

• sudo python manage.py runserver 0:80

Site now available at either of the following (no need for :80 as that is default for http):

• [Public DNS] i.e. ec2-54-528-27-21.compute-1.amazonaws.com
• [Public IP] i.e 75.254.65.19

Add following line in you .bashrc file

The best approach I've come up with is

1. Use lineage to store\sort\trace trees. That's more than enough, and works thousands times faster for reading than any other approach. It also allows to stay on that pattern even if DB will change(as ANY db will allow that pattern to be used)
2. Use function that determines lineage for specific ID.
3. Use it as you wish (in selects, or on CUD operations, or even by jobs).

Lineage approach descr. can be found wherever, for example Here or here. As of function - that is what enspired me.

In the end - got more-or-less simple, relatively fast, and SIMPLE solution.

        IF done THEN

        SET v_res = CONCAT(v_res,'-',v_papa);
    END LOOP;
    close csr;
    return v_res;
END

And then you just

select get_lineage(the_id)

Hope it helps somebody :)

As posted in my update above, a potential solution would be to use Declaration Merging as suggested by @Tyler-sebastion. I was able to define two additional interfaces and add the index property on the EventTarget in this way.

interface KonvaTextEventTarget extends EventTarget {
  index: number
}

interface KonvaMouseEvent extends React.MouseEvent<HTMLElement> {
  target: KonvaTextEventTarget
}

I then can declare the event as KonvaMouseEvent in my onclick MouseEventHandler function.

onClick={(event: KonvaMouseEvent) => {
          makeMove(ownMark, event.target.index)
}}

I'm still not 100% if this is the best approach as it feels a bit Kludgy and overly verbose just to get past the tslint error.

discussion

Using seq is fine, as Jiaaro suggested. Pax Diablo suggested a Bash loop to avoid calling a subprocess, with the additional advantage of being more memory friendly if $END is too large. Zathrus spotted a typical bug in the loop implementation, and also hinted that since i is a text variable, continuous conversions to-and-fro numbers are performed with an associated slow-down.

integer arithmetic

This is an improved version of the Bash loop:

typeset -i i END
let END=5 i=1
while ((i<=END)); do
    echo $i
    …
    let i++
done

If the only thing that we want is the echo, then we could write echo $((i++)).

ephemient taught me something: Bash allows for ((expr;expr;expr)) constructs. Since I've never read the whole man page for Bash (like I've done with the Korn shell (ksh) man page, and that was a long time ago), I missed that.

So,

typeset -i i END # Let's be explicit
for ((i=1;i<=END;++i)); do echo $i; done

seems to be the most memory-efficient way (it won't be necessary to allocate memory to consume seq's output, which could be a problem if END is very large), although probably not the “fastest”.

the initial question

eschercycle noted that the {a..b} Bash notation works only with literals; true, accordingly to the Bash manual. One can overcome this obstacle with a single (internal) fork() without an exec() (as is the case with calling seq, which being another image requires a fork+exec):

for i in $(eval echo "{1..$END}"); do

Both eval and echo are Bash builtins, but a fork() is required for the command substitution (the $(…) construct).

Getters and setters really only make sense when you have private properties of classes. Since Javascript doesn't really have private class properties as you would normally think of from Object Oriented Languages, it can be hard to understand. Here is one example of a private counter object. The nice thing about this object is that the internal variable "count" cannot be accessed from outside the object.

var counter = function() {
    var count = 0;

    this.inc = function() {
        count++;
    };

    this.getCount = function() {
        return count;
    };
};

var i = new Counter();
i.inc();
i.inc();
// writes "2" to the document
document.write( i.getCount());

If you are still confused, take a look at Crockford's article on Private Members in Javascript.

git push --all

is the canonical way to push everything to a new bare repository.

Another way to do the same thing is to create your new, non-bare repository and then make a bare clone with

git clone --bare

then use

git remote add origin <new-remote-repo>

in the original (non-bare) repository.

I think the answer depends on which features of stored procedures you need to use.

Stored procedures returning a result set can be run using Query; stored procedures which don't return a result set can be run using Execute - in both cases (using EXEC <procname>) as the SQL command (plus input parameters as necessary). See the documentation for more details.

As of revision 2d128ccdc9a2 there doesn't appear to be native support for OUTPUT parameters; you could add this, or alternatively construct a more complex Query command which declared TSQL variables, executed the SP collecting OUTPUT parameters into the local variables and finallyreturned them in a result set:

DECLARE @output int

EXEC <some stored proc> @i = @output OUTPUT

SELECT @output AS output1

EDIT 2

After three months we can say: no more official Google Apps in Genymotion and CyanogenMod-like method is only way to get Google Apps. However, you can still use the previous project of the Genymotion team: AndroVM (download mirror).

EDIT

Google apps will be removed from Genymotion in November. You can find more information on the Genymotion Google Plus page.

Choose virtual device with Google Apps:

Done:

1. You can just use localStorage and remember the date it was first created in session cookie. When localStorage "session" is older than the value of cookie then you may clear the localStorage

   Cons of this is that someone can still read the data after the browser is closed so it's not a good solution if your data is private and confidental.

2. You can store your data to localStorage for a couple of seconds and add event listener for a storage event. This way you will know when any of the tabs wrote something to the localStorage and you can copy its content to the sessionStorage, then just clear the localStorage

make sure you have GDB installed on your system...

If your using Linux based OS simply in a terminal type:

sudo apt-get install gdt 

when finished downloading extract the file and install.

close your IDE (in this case eclipse and open it again and run your project.

How about..

var result = (from s in context.Shift join es in employeeshift on s.shiftid equals es.shiftid where es.empid == 57 select s)

Edit: This will give you shifts where there is an associated employeeshift (because of the join). For the "not exists" I'd do what @ArsenMkrt or @hyp suggest

If yes_ans > no_ans and yes_ans > na_ans  

You're using column names in a statement (outside of a query). If you want variables, you must declare and assign them.

The argument to remove() is a filter document, so passing in an empty document means 'remove all':

db.user.remove({})

However, if you definitely want to remove everything you might be better off dropping the collection. Though that probably depends on whether you have user defined indexes on the collection i.e. whether the cost of preparing the collection after dropping it outweighs the longer duration of the remove() call vs the drop() call.

More details in the docs.

I suggest to make an invisible iframe on the page and set it's src to url that you've received from the server - download will start without page reloading.

Or you can just set the current document.location.href to received url address. But that's can cause for user to see an error if the requested document actually does not exists.

Plan: Write out the shuffle without relying on a library to do the heavy lifting. Example: Go through the list from the beginning starting with element 0; find a new random position for it, say 6, put 0’s value in 6 and 6’s value in 0. Move on to element 1 and repeat this process, and so on through the rest of the list

import random
iteration = random.randint(2, 100)
temp_var = 0
while iteration > 0:

    for i in range(1, len(my_list)): # have to use range with len()
        for j in range(1, len(my_list) - i):
            # Using temp_var as my place holder so I don't lose values
            temp_var = my_list[i]
            my_list[i] = my_list[j]
            my_list[j] = temp_var

        iteration -= 1

Another option if you want to preserve translucency and you don't want to subclass every UINavigationController in your app:

#import <objc/runtime.h>

@implementation UINavigationController (NoShadow)

+ (void)load {
    Method original = class_getInstanceMethod(self, @selector(viewWillAppear:));
    Method swizzled = class_getInstanceMethod(self, @selector(swizzled_viewWillAppear:));
    method_exchangeImplementations(original, swizzled);
}

+ (UIImageView *)findHairlineImageViewUnder:(UIView *)view {
    if ([view isKindOfClass:UIImageView.class] && view.bounds.size.height <= 1.0) {
        return (UIImageView *)view;
    }

    for (UIView *subview in view.subviews) {
        UIImageView *imageView = [self findHairlineImageViewUnder:subview];
        if (imageView) {
            return imageView;
        }
    }

    return nil;
}

- (void)swizzled_viewWillAppear:(BOOL)animated {
    UIImageView *shadow = [UINavigationController findHairlineImageViewUnder:self.navigationBar];
    shadow.hidden = YES;

    [self swizzled_viewWillAppear:animated];
}

png has a wider color pallete than gif and gif is properitary while png is not. gif can do animations, what normal-png cannot. png-transparency is only supported by browser roughly more recent than IE6, but there is a Javascript fix for that problem. Both support alpha transparency. In general I would say that you should use png for most webgraphics while using jpeg for photos, screenshots, or similiar because png compression does not work too good on thoose.

<input type="text" autocomplete="off"/>

Should work. Alternatively, use:

<form autocomplete="off" … >

for the entire form (see this related question).

You have to take care how you establish your mysqli connection. Full credit for this solution goes to Jorge Albarenque, source

In order to fix it I had to:

• Add local-infile=1 to the [mysqld] and [mysql] sections of my.cnf (as explained in the comments above)
• Use mysqli_real_connect function (PHP documentation).

The catch is that with that function you can explicitly enable the support for LOAD DATA LOCAL INFILE. For example (procedural style):

$link = mysqli_init();
mysqli_options($link, MYSQLI_OPT_LOCAL_INFILE, true);
mysqli_real_connect($link, $host, $username, $password, $database);

or object oriented

$mysqli = mysqli_init();
$mysqli->options(MYSQLI_OPT_LOCAL_INFILE, true);
$mysqli->real_connect($host, $username, $password, $database);

As one suggested, i went through implementation of resource bundle.. but that did not help.. as the bundle was always called under en_US locale... i tried to set my default locale to a different language and still my implementation of resource bundle control was being called with en_US... i tried to put log messages and do a step through debug and see if a different local call was being made after i change locale at run time through xhtml and JSF calls... that did not happend... then i tried to do a system set default to a utf8 for reading files by my server (tomcat server).. but that caused pronlem as all my class libraries were not compiled under utf8 and tomcat started to read then in utf8 format and server was not running properly... then i ended up with implementing a method in my java controller to be called from xhtml files.. in that method i did the following:

        public String message(String key, boolean toUTF8) throws Throwable{
            String result = "";
            try{
                FacesContext context = FacesContext.getCurrentInstance();
                String message = context.getApplication().getResourceBundle(context, "messages").getString(key);

                result = message==null ? "" : toUTF8 ? new String(message.getBytes("iso8859-1"), "utf-8") : message;
            }catch(Throwable t){}
            return result;
        }

I was particularly nervous as this could slow down performance of my application... however, after implementing this, it looks like as if my application is faster now.. i think it is because, i am now directly accessing the properties instead of letting JSF parse its way into accessing properties... i specifically pass Boolean argument in this call because i know some of the properties would not be translated and do not need to be in utf8 format...

Now I have saved my properties file in UTF8 format and it is working fine as each user in my application has a referent locale preference.

Use 'subset'

DF <- data.frame(x = c(1, 2, 3), y = c(0, 10, NA), z=c(NA, 33, 22))
subset(DF, !is.na(y))

In my case, IIS suddenly stoped working, and after that Windows process activation service was unable to restart.

The solution to fix this was:

1. Find WAS service in the services tab of windows task manager
2. In context menu choose Go to process
3. Kill process (its name will be svchost.exe)
4. Restart Windows process activation service

Hope it will be usefull.

From the root of the package do:

node -p "require('./package.json').version"

EDIT: (so you need to cd into the module's home directory if you are not already there. If you have installed the module with npm install, then it will be under node_modules/<module_name>)

EDIT 2: updated as per answer from @jeff-dickey

REST is somewhat of a revival of old-school HTTP, where the actual HTTP verbs (commands) have semantic meaning. Til recently, apps that wanted to update stuff on the server would supply a form containing an 'action' variable and a bunch of data. The HTTP command would almost always be GET or POST, and would be almost irrelevant. (Though there's almost always been a proscription against using GET for operations that have side effects, in reality a lot of apps don't care about the command used.)

With REST, you might instead PUT /profiles/cHao and send an XML or JSON representation of the profile info. (Or rather, I would -- you would have to update your own profile. :) That'd involve logging in, usually through HTTP's built-in authentication mechanisms.) In the latter case, what you want to do is specified by the URL, and the request body is just the guts of the resource involved.

http://en.wikipedia.org/wiki/Representational_State_Transfer has some details.

A small but important detail for adjusting figure size on a one-off basis (as several commenters above reported "this doesn't work for me"):

You should do plt.figure(figsize=(,)) PRIOR to defining your actual plot. For example:

This should correctly size the plot according to your specified figsize:

values = [1,1,1,2,2,3]
_ = plt.figure(figsize=(10,6))
_ = plt.hist(values,bins=3)
plt.show()

Whereas this will show the plot with the default settings, seeming to "ignore" figsize:

values = [1,1,1,2,2,3]
_ = plt.hist(values,bins=3)
_ = plt.figure(figsize=(10,6))
plt.show()

Half (but only half) snarky answer (the other half is bitter disdain of the reality of bureaucracy):

Use vh

Everything is always sized to browser window.

Always allow scroll down, but disable horizontal scroll.

Set body width to be a static 50vh, and never code css that floats or breaks out of the parent div. (If they try to mock up something that looks like it does, clever use of a background gif can throw them off track.) And style only using tables so everything is held rigidly into place as expected. Include a javascript function to undo any ctrl+/- activity the user may do.

Users will hate you, because the site doesn't flow differently based on what they're using (such as text being too small to read on phones). Your coworkers will hate you because nobody in their right mind does this and it will likely break their work (though not yours). Your programming professors will hate you because this is not a good idea. Your UX designer will hate you because it will reveal the corners they cut in designing UX mock-ups that they have to do in order to meet deadlines.

Nearly everyone will hate you, except the people who tell you to make things match the mock-up and to do so quickly. Those people, however (which generally include the project managers), will be ecstatic by your accuracy and fast turn around time. And everyone knows their opinion is the only one that matters to your paycheck.

You can try this:

Promise.resolve(JSON.parse(response)).then(json => {
    response = json ;
}).catch(err => {
    response = response
});

All code below was tested with Python 3.8.3

Simplest -- just use triple quotes.
Either single:

long_string = '''some
very 
long
string
............'''

or double:

long_string = """some
very 
long
string
............"""

Note: triple quoted strings retain indentation, it means that

long_string = """some
    very 
    long
string
............"""

and

long_string = """some
    very 
long
string
............"""

or even just

long_string = """
some
very 
long
string
............"""

are not the same.
There is a textwrap.dedent function in standard library to deal with this, though working with it is out of question's scope.

You can, as well, use \n inside a string, residing on single line:

long_string = "some \nvery \nlong \nstring \n............"

Also, if you don't need any linefeeds (i.e. newlines) in your string, you can use \ inside regular string:

long_string = "some \
very \
long \
string \
............"

Use the SimpleDateFormat class parse() method. This method will return a Date object. You can then create a Calendar object for this Date and add 2 hours to it.

SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = formatter.parse(theDateToParse);
Calendar cal = Calendar.getInstance();
cal.setTime(date);
cal.add(Calendar.HOUR_OF_DAY, 2);
cal.getTime(); // This will give you the time you want.

}

You don't.

Firstly, your question is ambiguous - do you mean the format in which it is displayed to the user, or the format in which it is transmitted to the web server?

If you mean the format in which it is displayed to the user, then this is down to the end-user interface, not anything you specify in the HTML. Usually, I would expect it to be based on the date format that it is set in the operating system locale settings. It makes no sense to try to override it with your own preferred format, as the format it displays in is (generally speaking) the correct one for the user's locale and the format that the user is used to writing/understanding dates in.

If you mean the format in which it's transmitted to the server, you're trying to fix the wrong problem. What you need to do is program the server-side code to accept dates in yyyy-mm-dd format.

I just encountered this issue and would recommend csvsql (releases) for bulk imports to Postgres. To perform a bulk insert you'd simply createdb and then use csvsql, which connects to your database and creates individual tables for an entire folder of CSVs.

$ createdb test 
$ csvsql --db postgresql:///test --insert examples/*.csv

Whether you use currentframe().f_back depends on whether you are using a function or not.

Calling inspect directly:

from inspect import currentframe, getframeinfo

cf = currentframe()
filename = getframeinfo(cf).filename

print "This is line 5, python says line ", cf.f_lineno 
print "The filename is ", filename

Calling a function that does it for you:

from inspect import currentframe

def get_linenumber():
    cf = currentframe()
    return cf.f_back.f_lineno

print "This is line 7, python says line ", get_linenumber()

using System;
using System.Linq;

class Program
{
    static void Main(string[] args)
    {
        int[] numbers = { 3, 9, 5 };
        int biggestNumber = numbers.Max();
        Console.WriteLine(biggestNumber);
        Console.ReadLine();
    }
}

To remove spaces... please use LTRIM/RTRIM

 LTRIM(String)
 RTRIM(String)

The String parameter that is passed to the functions can be a column name, a variable, a literal string or the output of a user defined function or scalar query.

SELECT LTRIM(' spaces at start')
SELECT RTRIM(FirstName) FROM Customers

Try changing the encoding. In my case, encoding = "utf-16" worked.

df = pd.read_csv("file.csv",encoding='utf-16')

Try the following:

<a asp-controller="Users" asp-action="Index"></a>

(Valid for ASP.NET 5 and MVC 6)

As this is tagged with the extjs tag it may be worth looking at the extjs method: http://docs.sencha.com/extjs/6.2.0/classic/Ext.Function.html#method-interval

This works much like setInterval, but also takes care of the scope, and allows arguments to be passed too:

function setBgPosition() {
    var c = 0;
    var numbers = [0, -120, -240, -360, -480, -600, -720];
    function run() {
       Ext.get('common-spinner').setStyle('background-position', numbers[c++] + 'px 0px');
        if (c<numbers.length){
            c=0;
        }
    }
    return Ext.Function.interval(run,200);
}

var bgPositionTimer = setBgPosition();

when you want to stop you can use clearInterval to stop it

clearInterval(bgPositionTimer);

An example use case would be:

Ext.Ajax.request({
    url: 'example.json',

    success: function(response, opts) {
        clearInterval(bgPositionTimer);
    },

    failure: function(response, opts) {
        console.log('server-side failure with status code ' + response.status);
        clearInterval(bgPositionTimer);
    }
});

Although System.Collections.Generic.Dictionary matches the tag "hashmap" and will work well in your example, it is not an exact equivalent of C++'s std::map - std::map is an ordered collection.

If ordering is important you should use SortedDictionary.

Please try this

error_reporting = E_ALL & ~E_NOTICE

in php.ini

It might be due to "client profile" of the .NET Framework. Try to use the "full version" of .NET.

Extending Piotr's answer, if you also need a way to figure what to put in requirements.in, you can first use pip-chill to find the minimal set of required packages you have. By combining these tools, you can show the dependency reason why each package is installed. The full cycle looks like this:

1. Create virtual environment:
   $ python3 -m venv venv
2. Activate it:
   $ . venv/bin/activate
3. Install newest version of pip, pip-tools and pip-chill:
   (venv)$ pip install --upgrade pip
(venv)$ pip install pip-tools pip-chill
4. Build your project, install more pip packages, etc, until you want to save...
5. Extract minimal set of packages (ie, top-level without dependencies):
   (venv)$ pip-chill --no-version > requirements.in
6. Compile list of all required packages (showing dependency reasons):
   (venv)$ pip-compile requirements.in
7. Make sure the current installation is synchronized with the list:
   (venv)$ pip-sync

I tried the answers above but the generated script file was very large and I was having problems while importing the data. I ended up Detaching the database, then copying .mdf to my new machine, then Attaching it to my new version of SQL Server Management Studio.

I found instructions for how to do this on the Microsoft Website:
https://msdn.microsoft.com/en-us/library/ms187858.aspx

NOTE: After Detaching the database I found the .mdf file within this directory:
C:\Program Files\Microsoft SQL Server\

So simple, all you need is to change the address in the config client: instead of 'localhost' change to the machine name or IP

psql: Logs me in with my default username

psql -U postgres: Logs me in as the postgres user

Sudo doesn't seem to be required for me.

I use Postgres.app for my OS X postgres database. It removed the headache of making sure the installation was working and the database server was launched properly. Check it out here: http://postgresapp.com

The pylab examples page is a very useful source. The example relevant for your question:

http://matplotlib.sourceforge.net/mpl_examples/pylab_examples/scatter_demo2.py http://matplotlib.sourceforge.net/users/screenshots.html#scatter-demo

You're nearly there, just take out the EXECUTE:

DECLARE
  procId NUMBER;

BEGIN
  PKG1.INIT(1143824, 0, procId);
  DBMS_OUTPUT.PUT_LINE(procId);
END;

1. In AndroidManifest.xml:

   • At application, add tools:replace="android:icon, android:theme and
   • At the Manifest root, add xmlns:tools="http://schemas.android.com/tools

2. In build.gradle:

   • At root, add useOldManifestMerger true

What you are asking is pretty straight forward

1. execute query against your db to get resultset or use API to get the resultset

2. loop through the resultset or simply the result using php

3. In each iteration simply format the output as an element

^ is the Python bitwise XOR operator. It is how you spell XOR in python:

>>> 0 ^ 0
0
>>> 0 ^ 1
1
>>> 1 ^ 0
1
>>> 1 ^ 1
0

XOR stands for exclusive OR. It is used in cryptography because it let's you 'flip' the bits using a mask in a reversable operation:

>>> 10 ^ 5
15
>>> 15 ^ 5
10

where 5 is the mask; (input XOR mask) XOR mask gives you the input again.

This line is causing problems:

(-b+math.sqrt(b**2-4*a*c))/2*a

x/2*a is interpreted as (x/2)*a. You need more parentheses:

(-b + math.sqrt(b**2 - 4*a*c)) / (2 * a)

Also, if you're already storing d, why not use it?

x = (-b + math.sqrt(d)) / (2 * a)

http://msdn.microsoft.com/en-us/library/f02979c7(v=VS.90).aspx

You can pass nothing if you don't need the returned integer like so

if integer.TryParse(number,nothing) then

preg_match('/'.preg_quote('^\'£$%^&*()}{@#~?><,@|-=-_+-¬', '/').'/', $string);

This is my main activity where i take the username and password from edit text and setting to the intent

class MainActivity : AppCompatActivity() {
val userName = null
val password = null
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
button.setOnClickListener {
    val intent = Intent(this@MainActivity,SecondActivity::class.java);
    var userName = username.text.toString()
    var password = password_field.text.toString()
    intent.putExtra("Username", userName)
    intent.putExtra("Password", password)
    startActivity(intent);
 }
}

This is my second activity where i have to receive values from the main activity

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_second)
var strUser: String = intent.getStringExtra("Username")
var strPassword: String = intent.getStringExtra("Password")
user_name.setText("Seelan")
passwor_print.setText("Seelan")
}

The easiest way is to put the declaration and definition in the same file, but it may cause over-sized excutable file. E.g.

class Foo
{
public:
template <typename T> void some_method(T t) {//...}
}

Also, it is possible to put template definition in the separate files, i.e. to put them in .cpp and .h files. All you need to do is to explicitly include the template instantiation to the .cpp files. E.g.

// .h file
class Foo
{
public:
template <typename T> void some_method(T t);
}

// .cpp file
//...
template <typename T> void Foo::some_method(T t) 
{//...}
//...

template void Foo::some_method<int>(int);
template void Foo::some_method<double>(double);

I know this is a very old question but this is more for someone else who might have the same problem and I think this is more accurate to what was wanted.

SELECT * FROM member WHERE email = (Select email From member Where login_id = [email protected]) 

This will return all records that have [email protected] as a login_id value.

You need

ALTER TABLE YourTable ALTER COLUMN YourColumn <<new_datatype>> [NULL | NOT NULL]

But remember to specify NOT NULL explicitly if desired.

ALTER TABLE YourTable ALTER COLUMN YourColumn VARCHAR (500) NOT NULL;

If you leave it unspecified as below...

ALTER TABLE YourTable ALTER COLUMN YourColumn VARCHAR (500);

Then the column will default to allowing nulls even if it was originally defined as NOT NULL. i.e. omitting the specification in an ALTER TABLE ... ALTER COLUMN is always treated as.

ALTER TABLE YourTable ALTER COLUMN YourColumn VARCHAR (500) NULL;

This behaviour is different from that used for new columns created with ALTER TABLE (or at CREATE TABLE time). There the default nullability depends on the ANSI_NULL_DFLT settings.

I have worked with SAP since 1998. SAP is a type of software called ERP (Enterprise Resource Planning) that large companies use to manage their day to day affairs. On the macro, the software can be split into two categories: Technical and Functional

Let's go Technical first, as it answers the "What is ABAP" part of your question.

Technical

There are two technical "stacks" within the SAP software, the first is the ABAP stack which is inclusive of all the original technology that SAP was. ABAP is the proprietary coding language for SAP to develop RICEFW objects (Reports, Interfaces, Conversions, Extensions, Forms and Workflows) within the ABAP stack.

The ABAP stack is traditionally navigated via Transaction Codes (T-Codes) to take you to different screens within the SAP Environment. From a technical perspective, you will do all of your performance and tuning of the WORK PROCESSES in the SAP system here, as well as configuring all of the system RFCs, building user profiles and also doing the necessary interfacing between the OS (usually Windows or HPUX) and the Oracle Database (currently Enterprise 11g).

The JAVA stack controls the "Netweaver" aspect of SAP which encapsulates SAP's ability to be accessed via the Internet via SAP Portal and it's ability to interface with other SAP and non-SAP legacy systems via Process Integration (PI).

SAP also has extensive capabilities in the Business Intelligence Field (BI) by accessing information stored within the Business Warehouse (BW). Currently, there is a new technology called HANA 1.0 that compresses the time to run reports against these repositories.

There are two primarily technologists that run ALL of these functions, they are called SAP Basis (Netweaver) Administrators and ABAP Developers.

Functional

SAP has specific pre-populated functional packages for different business areas. For example, Exxon runs the "IS Oil & Gas" package while Bank of America runs the "Banking" package, while further still Lockheed Martin runs the "Aerospace & Defense" package. These packages were developed over time by the amalgamation of intelligent functional customizations that could be intelligently ported to the system via inclusion in dot releases.

However, there are some vanilla functional modules that almost all entities run, regardless of their specific industry:

• HR: Human Resources
• PM: Project Management
• FI: Financial
• CO: Controllers
• MM: Materials Management
• SD: Sales and Distribution
• PP: Production Planning

and finally the biggie:

• MDM: Master Data Management which encapsulates the data for customer/vendor/material etc.

just found an advance and most currently used method to set string in textView

textView.setText(String.valueOf(YourIntegerNumber));

I would like to add an answer that I do not see here. It is very related to the accepted answer, however, I did not have duplicated properties on my model, it was an issue with my Javascript.

I was doing some Ajax save where I was rebuilding the model to send back to the server. When I had first initialized the page I set my original model to a variable:

var currentModel = result.Data;

My result.Data has a property: result.Data.Items

So, some time later, I do some things and want to save, via Ajax. Part of the process is to grab an array from some side process and set it to my currentModel.Items property and send currentModel to the server.

In my Javascript, however, I did this, instead:

currentModel.items = getData();

I didn't catch it, but in Visual Studio, it will auto lower case the first letter for Javascript properties (it could be a ReSharper thing too). Then, I got the exact error posted by OP when I tried to save because currentModel now has currentModel.items AND currentModel.Items

A simple change from "items" to "Items" fixed the problem.

A Container can take a BoxDecoration (going off of the code you had originally posted) which takes a boxShadow:

decoration: BoxDecoration(
    borderRadius: BorderRadius.circular(10),
    boxShadow: [
        BoxShadow(
            color: Colors.grey.withOpacity(0.5),
            spreadRadius: 5,
            blurRadius: 7,
            offset: Offset(0, 3), // changes position of shadow
        ),
    ],
),

Sort integers > 0, think outside the box:

function sortArray(arr) {
  return new Promise((resolve) => {
    const result = []
    arr.forEach((item) => {
      setTimeout(() => {
        result.push(item)
        if (result.length === arr.length) resolve(result)
      }, item)
    })
  })
}

sortArray([4, 2, 42, 128, 56, 2]).then((result) => {
  document.write(JSON.stringify(result))
})

Note that this should not be used productively, .sort() is better suited for this, check the other answers

Another open source tool for this is Cloud Query https://docs.cloudquery.io/

I was facing the same issue in which I need to align selected placeholder value to the right of the select box & also need to align options to right but when I have used direction: rtl; to select & applied some right padding to select then all options also getting shift to the right by padding as I only want to apply padding to selected placeholder.

I have fixed the issue by the following the style:

select:first-child{
  text-indent: 24%;
  direction: rtl;
  padding-right: 7px;
}

select option{
  direction: rtl;
}

You can change text-indent as per your requirement. Hope it will help you.

Try this:

       import java.net.HttpURLConnection;

       URL url = new URL("http://www.myurl.com/sample.xml");

       HttpURLConnection huc = (HttpURLConnection) url.openConnection();
       HttpURLConnection.setFollowRedirects(false);
       huc.setConnectTimeout(15 * 1000);
       huc.setRequestMethod("GET");
       huc.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.2) Gecko/20090729 Firefox/3.5.2 (.NET CLR 3.5.30729)");
       huc.connect();
       InputStream input = huc.getInputStream();

OR

       import org.jsoup.nodes.Document;

       Document doc = null;
       try {
           doc = Jsoup.connect("http://www.myurl.com/sample.xml").get();
       } catch (Exception e) {
           //log error
       }

And take look on how to use Jsoup: http://jsoup.org/cookbook/input/load-document-from-url

If your dropdown is something like this:

<select id="thedropdown">
  <option value="1">one</option>
  <option value="2">two</option>
</select>

Then you would use something like:

var a = document.getElementById("thedropdown");
alert(a.options[a.selectedIndex].value);

But a library like jQuery simplifies things:

alert($('#thedropdown').val());

You say you have been asked to show a progress bar while a large file is loading. Is that because the users genuinely want to see the exact % of file loading, or just because they want visual feedback that something is happening?

If the latter is true, then the solution becomes much simpler. Just do reader.ReadToEnd() on a background thread, and display a marquee-type progress bar instead of a proper one.

I raise this point because in my experience this is often the case. When you are writing a data processing program, then users will definitely be interested in a % complete figure, but for simple-but-slow UI updates, they are more likely to just want to know that the computer hasn't crashed. :-)

You are testing against the string minus the last character:

>>> '"xxx"'[:-1]
'"xxx'

Note how the last character, the ", is not part of the output of the slice.

I think you wanted just to test against the last character; use [-1:] to slice for just the last element.

However, there is no need to slice here; just use str.startswith() and str.endswith() directly.

CARL LANGE also showed how to get hidden, autoplaying audio in html5 on a iOS device. Works for me.

In HTML,

<div id="hideme">
    <audio id="audioTag" controls>
        <source src="/path/to/audio.mp3">
    </audio>
</div>

with JS

<script type="text/javascript">
window.onload = function() {
    var audioEl = document.getElementById("audioTag");
    audioEl.load();
    audioEl.play();
};
</script>

In CSS,

#hideme {display: none;}

The most effective solution that I found is to define the parent element with display:flex and align-items:center

LIVE DEMO

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <style>
      .myclass{
        display:flex;
        align-items:center;
        background-color:grey;
        color:#fff;
        height:50px;
      }
    </style>
  </head>
  <body>
    <div class="myclass">
      <input type="checkbox">
      <label>do you love Ananas?
      </label>
    </div>
  </body>
</html>

OUTPUT:

A bit late but I thought I'd share in case it helps anyone: what is most likely the problem is simply that your Debug Console (the command line window that opens when run your project if it is a Windows Console Application) is still open from the last time you ran the code. Just close that window, then rebuild and run: Ctrl + B and F5, respectively.

-- Access: 
SELECT CHR(13) & CHR(10) 

-- SQL Server: 
SELECT CHAR(13) + CHAR(10)

Since XCode 4.3 the location has changed, the simulator can now be found at:

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneSimulator.platform/Developer/Applications/

 protected void Application_Start(object sender, EventArgs e)
 {
     string path = Server.MapPath("/");
     //or 
     string path2 = Server.MapPath("~");
     //depends on your application needs

 }

What you need is something that calculates the result of the infix notated calculation, have a look at the Shunting-Yard Algorithm.

There's an example in C++ on Wikipedia's page, but it shouldn't be too hard to implement it in Java.
And since it's the primary function of your calculator, I would advise you to not grab some codez from the Web in this Case (except all you want to do is building calculator GUIs).

This is how you initialize and also you can use List.Add() in case you want to make it more dynamic.

List<string> optionList = new List<string> {"AdditionalCardPersonAdressType"};
optionList.Add("AutomaticRaiseCreditLimit");
optionList.Add("CardDeliveryTimeWeekDay");

In this way, if you are taking values in from IO, you can add it to a dynamically allocated list.

Remove the comma?

select /*+USE_HASH( a b ) */ to_char(date, 'MM/DD/YYYY HH24:MI:SS') as LABEL,
ltrim(rtrim(substr(oled, 9, 16))) as VALUE
from rrfh a, rrf b
where ltrim(rtrim(substr(oled, 1, 9))) = 'stata kish' 
and a.xyz = b.xyz

Have a look at FROM

SELECTING from multiple tables You can include multiple tables in the FROM clause by listing the tables with a comma in between each table name

For Xcode 6 it is a little different.

After adding the device UDID in the developer site (https://developer.apple.com/account/ios/device/deviceList.action), go back to Xcode.

Xcode -> Preferences -> Accounts Select the Apple ID you added the device under and in the bottom right, click "View Details..."

Hit the refresh icon on the bottom left and then try to run the app again.

I had the same problem when I wrote two upstreams in NGINX conf

upstream php_upstream {
    server unix:/var/run/php/my.site.sock;
    server 127.0.0.1:9000;
}

...

fastcgi_pass php_upstream;

but in /etc/php/7.3/fpm/pool.d/www.conf I listened the socket only

listen = /var/run/php/my.site.sock

So I need just socket, no any 127.0.0.1:9000, and I just removed IP+port upstream

upstream php_upstream {
    server unix:/var/run/php/my.site.sock;
}

This could be rewritten without an upstream

fastcgi_pass unix:/var/run/php/my.site.sock;

In pthread_exit, ret is an input parameter. You are simply passing the address of a variable to the function.

In pthread_join, ret is an output parameter. You get back a value from the function. Such value can, for example, be set to NULL.

Long explanation:

In pthread_join, you get back the address passed to pthread_exit by the finished thread. If you pass just a plain pointer, it is passed by value so you can't change where it is pointing to. To be able to change the value of the pointer passed to pthread_join, it must be passed as a pointer itself, that is, a pointer to a pointer.

The standard unix diff will show if the files are the same or not:

[me@host ~]$ diff 1.bin 2.bin
Binary files 1.bin and 2.bin differ

If there is no output from the command, it means that the files have no differences.

There are a number of ways to create arrays.

The traditional way of declaring and initializing an array looks like this:

var a = new Array(5); // declare an array "a", of size 5
a = [0, 0, 0, 0, 0];  // initialize each of the array's elements to 0

Or...

// declare and initialize an array in a single statement
var a = new Array(0, 0, 0, 0, 0); 

The other answers are correct as to "how" to resize them, but I would also thrown in the recommendation to just grab the resolution you are interested in, to begin with. Most Android devices offer a range of resolutions and you should pick one that gives you a file size that you're comfortable with. The biggest reason for this is that the native Android scaling algorithm (as detailed by Jin35 and Padma Kumar) produces pretty crappy results. It's not going to give you Photoshop quality resizing, even downscaling (to say nothing of upscaling, which I know you're not asking about, but that's just a non-starter).

So, you should try their solution and if you're happy with the outcome, great. But if not, I'd write a function that offers a range of width that you're happy with, and looks for that dimension (or whatever's closest) in the device's available picture size array and just set it and use it.

For MS SQL Server:

select * from information_schema.columns where table_name = 'tableName'

import numpy as np 

... ## other code

some list comprehension

t=[nodel[ nodenext[i][j] ] for j in idx]
            #for each link, find the node lables 
            #t is the list of node labels 

Convert the list to a numpy array using the array method specified in the numpy library.

t=np.array(t)

an existing folder will FAIL with FileExists

Function FileExists(strFileName)
' Check if a file exists - returns True or False

use instead or in addition:

Function FolderExists(strFolderPath)
' Check if a path exists

A quick way to explain this is to visualize it.

if both i and j are from 0 to N, it's easy to see O(N^2)

O O O O O O O O
O O O O O O O O
O O O O O O O O
O O O O O O O O
O O O O O O O O
O O O O O O O O
O O O O O O O O
O O O O O O O O

in this case, it's:

O
O O
O O O
O O O O
O O O O O
O O O O O O
O O O O O O O
O O O O O O O O

This comes out to be 1/2 of N^2, which is still O(N^2)

You can't.

There are steps you can take to make it a little more difficult, but ultimately any executable on the local machine is crackable. Eventually, that code has to be converted into native machine code and every application that is runnable is vulnerable.

What you want to do is just make it difficult enough to crack to make it not worth peoples' trouble.

Some suggestions I have for you to help protect your application:

• Obfuscate your code. Dotfuscator has a free edition and comes with Visual Studio.
• Use public/private key or asymmetric encryption to generate your product licenses. This ensures that only you can generate your license codes. Even if your application is cracked, you can be sure that they won't be releasing a key generator for your application, because it is impossible to reverse the key generating algorithm.
• Use a third-party packer to pack your .NET executable into an encrypted Win32 wrapper application. Themida is one of the better ones. This stops people from reflecting your application in .NET Reflector and makes it a pain to unpack for reversing.
• Write your own custom packer. If the third-party packers are too expensive, consider writing your own. Sometimes custom packers can be very effective, because there aren't well published methods on how to unpack them. The tutorial How to write your own packer gives a ton of good information on writing your own Win32 packer.

Ultimately though, if people want your application cracked they will. Look at all the commercial software out there that has a vast amount of resources to protect their applications and yet they are cracked before the applications are even released to the public.

A skilled reverse engineer can fire up IDA-Pro and slice through your application like butter no matter what you do. A packed application can be unpacked and obfuscation only prevents it from making it a walk in the park. All your hard work with your complex license code can be undone with a single byte patch.

You just need to accept that there is a very real chance people are going to pirate your software. There are some people who are never going to pay for your application no matter what and these are the people you don't need to worry about.

There are however, many businesses out there who would never risk a lawsuit and happily buy software licenses and many computer users who either don't want to risk it, find it wrong or are not tech savvy enough to pirate. These are your true customers, and you should focus your efforts on providing them with a good user experience and ignore the people cracking your software.

I've had my application pirated before, and I took it as a personal affront. Here I was, a small-time developer, pouring my heart and soul into an application and these people had the gall to pirate from me?! They were taking money directly from my pocket!

I immediately added in a bunch of draconian DRM code and attempted to sabotage any person using an illegitimate or cracked copy. I should of course have been working on making my application better instead of trying to stop the inevitable. Not only that, but I was hurting my true customers will all these extra protections I was putting in.

After a long battle I realized I was fighting the tides and all this time wasted was for naught. I took out all the phone-home code except for the barebones license functions and never looked back.

//if(data="undefined"){

This is an assignment statement, not a comparison. Also, "undefined" is a string, it's a property. Checking it is like this: if (data === undefined) (no quotes, otherwise it's a string value)

If it's not defined, you may be returning an empty string. You could try checking for a falsy value like if (!data) as well

Here is an example to call your webservice using jQuery.get:

$.get("http://domain.com/webservice.asmx", { name: "John", time: "2pm" },
  function(data){
    alert("Data Loaded: " + data);
  });

In the example above, we call "webservice.asmx", passing two parameters: name and time. Then, getting the service output in the call back function.

When not told otherwise commands take over the foreground. You only have one "foreground" process running in a single shell session. The & symbol instructs commands to run in a background process and immediately returns to the command line for additional commands.

sh my_script.sh &

A background process will not stay alive after the shell session is closed. SIGHUP terminates all running processes. By default anyway. If your command is long-running or runs indefinitely (ie: microservice) you need to pr-pend it with nohup so it remains running after you disconnect from the session:

nohup sh my_script.sh &

EDIT: There does appear to be a gray area regarding the closing of background processes when & is used. Just be aware that the shell may close your process depending on your OS and local configurations (particularly on CENTOS/RHEL): https://serverfault.com/a/117157.

Well I am a JavaScript developer and will try to explain its significance pertaining to JavaScript.

Consider a scenario where you want to match cat is animal when you would like match cat and animal and both should have a is in between them.

 // this will ignore "is" as that's is what we want
"cat is animal".match(/(cat)(?: is )(animal)/) ;
result ["cat is animal", "cat", "animal"]

 // using lookahead pattern it will match only "cat" we can
 // use lookahead but the problem is we can not give anything
 // at the back of lookahead pattern
"cat is animal".match(/cat(?= is animal)/) ;
result ["cat"]

 //so I gave another grouping parenthesis for animal
 // in lookahead pattern to match animal as well
"cat is animal".match(/(cat)(?= is (animal))/) ;
result ["cat", "cat", "animal"]

 // we got extra cat in above example so removing another grouping
"cat is animal".match(/cat(?= is (animal))/) ;
result ["cat", "animal"]

I am not sure what you mean by doing a depth first search on a rectangular array, but I assume you know what you are doing.

If the stack limit is a problem you should be able to convert your recursive solution into an iterative solution that pushes intermediate values onto a stack which is allocated from the heap.

Python String rindex() Method

Description
Python string method rindex() returns the last index where the substring str is found, or raises an exception if no such index exists, optionally restricting the search to string[beg:end].

Syntax
Following is the syntax for rindex() method -

str.rindex(str, beg=0 end=len(string))

Parameters
str - This specifies the string to be searched.

beg - This is the starting index, by default its 0

len - This is ending index, by default its equal to the length of the string.

Return Value
This method returns last index if found otherwise raises an exception if str is not found.

Example
The following example shows the usage of rindex() method.

Live Demo

!/usr/bin/python

str1 = "this is string example....wow!!!";
str2 = "is";

print str1.rindex(str2)
print str1.index(str2)

When we run above program, it produces following result -

5

I found that I had the same problem when I was running a project and debugging by attaching to an IIS process. I also was running in Debug mode with optimizations turned off. While I thought the code compiled fine, when I detached and tried to compile, one of the references was not found. This was due to another developer here that made modifications and changed the location of the reference. The reference did not show up with the alert symbol, so I thought everything was fine until I did the compilation. Once fixing the reference and running again it worked.

it's like this :)

window.addEventListener("scroll", (event) => {
    let scroll = this.scrollY;
    console.log(scroll)
});

Lately I've come across yet another way of putting JS code inside PHP code. It involves Heredoc PHP syntax. I hope it'll be helpful for someone.

<?php
$script = <<< JS

$(function() {
   // js code goes here
});

JS;
?>

After closing the heredoc construction the $script variable contains your JS code that can be used like this:

<script><?= $script ?></script>

The profit of using this way is that modern IDEs recognize JS code inside Heredoc and highlight it correctly unlike using strings. And you're still able to use PHP variables inside of JS code.

When looking for the existence of a element in an array, proper casting is required to pass the SQL parser of postgres. Here is one example query using array contains operator in the join clause:

For simplicity I only list the relevant part:

table1 other_name text[]; -- is an array of text

The join part of SQL shown

from table1 t1 join table2 t2 on t1.other_name::text[] @> ARRAY[t2.panel::text]

The following also works

on t2.panel = ANY(t1.other_name)

I am just guessing that the extra casting is required because the parse does not have to fetch the table definition to figure the exact type of the column. Others please comment on this.

if you want smooth scrolling add behavior configuration.

document.getElementById('id').scrollIntoView({
  behavior: 'smooth'
});

Use the rtrim function:

rtrim($my_string, ',');

The Second parameter indicates the character to be deleted.

if while In visual studio with IIS express working and when published failed try this:

I coded a function (used in Django project for DecimalField) but it can be used in Python project :

This code :

• Manage integers digits to avoid too high number
• Manage decimals digits to avoid too low number
• Manage signed and unsigned numbers

Code with tests :

def convert_decimal_to_right(value, max_digits, decimal_places, signed=True):

    integer_digits = max_digits - decimal_places
    max_value = float((10**integer_digits)-float(float(1)/float((10**decimal_places))))

    if signed:
        min_value = max_value*-1
    else:
        min_value = 0

    if value > max_value:
        value = max_value

    if value < min_value:
        value = min_value

    return round(value, decimal_places)


value = 12.12345
nb = convert_decimal_to_right(value, 4, 2)
# nb : 12.12

value = 12.126
nb = convert_decimal_to_right(value, 4, 2)
# nb : 12.13

value = 1234.123
nb = convert_decimal_to_right(value, 4, 2)
# nb : 99.99

value = -1234.123
nb = convert_decimal_to_right(value, 4, 2)
# nb : -99.99

value = -1234.123
nb = convert_decimal_to_right(value, 4, 2, signed = False)
# nb : 0

value = 12.123
nb = convert_decimal_to_right(value, 8, 4)
# nb : 12.123

ORDER BY column OFFSET 0 ROWS

Surprisingly makes it work, what a strange feature.

A bigger example with a CTE as a way to temporarily "store" a long query to re-order it later:

;WITH cte AS (
    SELECT .....long select statement here....
)

SELECT * FROM 
(
    SELECT * FROM 
    ( -- necessary to nest selects for union to work with where & order clauses
        SELECT * FROM cte WHERE cte.MainCol= 1 ORDER BY cte.ColX asc OFFSET 0 ROWS 
    ) first
    UNION ALL
    SELECT * FROM 
    (  
        SELECT * FROM cte WHERE cte.MainCol = 0 ORDER BY cte.ColY desc OFFSET 0 ROWS 
    ) last
) as unionized
ORDER BY unionized.MainCol desc -- all rows ordered by this one
OFFSET @pPageSize * @pPageOffset ROWS -- params from stored procedure for pagination, not relevant to example
FETCH FIRST @pPageSize ROWS ONLY -- params from stored procedure for pagination, not relevant to example

So we get all results ordered by MainCol

But the results with MainCol = 1 get ordered by ColX

And the results with MainCol = 0 get ordered by ColY

In the config file, change the "host" variable to point to the external server. The config file is called config.inc.php and it will be in the main phpMyAdmin folder. There should be a line like this:

$cfg['Servers'][$i]['host'] = 'localhost';

Just change localhost to your server's IP address.

Note: you may have to configure the external server to allow remote connections, but I've done this several times on shared hosting so it should be fine.

You'll want to:

• Read in an entire line from the console
• Tokenize the line, splitting along spaces.
• Place those split pieces into an array or list
• Step through that array/list, performing your prime/perfect/etc tests.

What has your class covered along these lines so far?

The listFiles method, with or without a filter does not guarantee any order.

It does, however, return an array, which you can sort with Arrays.sort().

File[] files = XMLDirectory.listFiles(filter_xml_files);
Arrays.sort(files);
for(File _xml_file : files) {
    ...
}

This works because File is a comparable class, which by default sorts pathnames lexicographically. If you want to sort them differently, you can define your own comparator.

If you prefer using Streams:

A more modern approach is the following. To print the names of all files in a given directory, in alphabetical order, do:

Files.list(Paths.get(dirName)).sorted().forEach(System.out::println)

Replace the System.out::println with whatever you want to do with the file names. If you want only filenames that end with "xml" just do:

Files.list(Paths.get(dirName))
    .filter(s -> s.toString().endsWith(".xml"))
    .sorted()
    .forEach(System.out::println)

Again, replace the printing with whichever processing operation you would like.

Old question, but my solution is a bit different.

I was writing a single page web app that was constantly making ajax calls triggered by the user, and to make it even more difficult it required libraries that used methods other than jquery (like dojo, native xhr, etc). I wrote a plugin for one of my own libraries to cache ajax requests as efficiently as possible in a way that would work in all major browsers, regardless of which libraries were being used to make the ajax call.

The solution uses jSQL (written by me - a client-side persistent SQL implementation written in javascript which uses indexeddb and other dom storage methods), and is bundled with another library called XHRCreep (written by me) which is a complete re-write of the native XHR object.

To implement all you need to do is include the plugin in your page, which is here.

There are two options:

jSQL.xhrCache.max_time = 60;

Set the maximum age in minutes. any cached responses that are older than this are re-requested. Default is 1 hour.

jSQL.xhrCache.logging = true;

When set to true, mock XHR calls will be shown in the console for debugging.

You can clear the cache on any given page via

jSQL.tables = {}; jSQL.persist();

Very good question indeed. I just tried for myself.

public class IsInstanceOfTest {

    public static void main(final String[] args) {

        String s;

        s = "";

        System.out.println((s instanceof String));
        System.out.println(String.class.isInstance(s));

        s = null;

        System.out.println((s instanceof String));
        System.out.println(String.class.isInstance(s));
    }
}

Prints

true

false
false

JLS / 15.20.2. Type Comparison Operator instanceof

At run time, the result of the instanceof operator is true if the value of the RelationalExpression is not null and the reference could be cast to the ReferenceType without raising a ClassCastException. Otherwise the result is false.

API / Class#isInstance(Object)

If this Class object represents an interface, this method returns true if the class or any superclass of the specified Object argument implements this interface; it returns false otherwise. If this Class object represents a primitive type, this method returns false.

When modules are in parallel locations, as in the question:

application/app2/some_folder/some_file.py
application/app2/another_folder/another_file.py

This shorthand makes one module visible to the other:

import sys
sys.path.append('../')

Assuming you can only have one 'something1' or 'something2', etc. per line, you can use a lookup table:

$lookupTable = @{
    'something1' = 'something1aa'
    'something2' = 'something2bb'
    'something3' = 'something3cc'
    'something4' = 'something4dd'
    'something5' = 'something5dsf'
    'something6' = 'something6dfsfds'
}

$original_file = 'path\filename.abc'
$destination_file =  'path\filename.abc.new'

Get-Content -Path $original_file | ForEach-Object {
    $line = $_

    $lookupTable.GetEnumerator() | ForEach-Object {
        if ($line -match $_.Key)
        {
            $line -replace $_.Key, $_.Value
            break
        }
    }
} | Set-Content -Path $destination_file

If you can have more than one of those, just remove the break in the if statement.

From what I understand you want to make a navigation bar or something similar to it. What I recommend doing is making a list and editing the items from there. Just try this;

<ul>
    <li class='item col-md-12 panel' id='gameplay-title'>Title</li>
    <li class='item col-md-6 col-md-offset-3 panel' id='gameplay-scoreboard'>Scoreboard</li>
</ul>

And so on... To add more categories add another ul in there. Now, for the CSS you just need this;

ul {
    list-style: none;
}
.item {
    display: inline;
    padding-right: 20px;
}

For something a little more readable, run this command once:

git config --global alias.lg "log --graph --pretty=format:'%Cred%h%Creset -%C(yellow)%d%Creset %s %Cgreen(%cr) %C(bold blue)<%an>%Creset' --abbrev-commit --date=relative"

so that when you then run:

git lg

you get a nice readout. To show only the last line:

git lg -1

Just a shot in the dark(since you did not share the compiler initialization code with us): the way you retrieve the compiler causes the issue. Point your JRE to be inside the JDK as unlike jdk, jre does not provide any tools hence, results in NPE.

For others who wind up here like I did, you can use AJAX to do a PUT with parameters, but they are sent as the body, not as query strings.

After coming back to my own question after 5 year and seeing so many people found this useful, a little update.

A string variable can be split into a list by using the split function (it can contain similar values, set is for the assignment) . I haven't found this function in the official documentation but it works similar to normal Python. The items can be called via an index, used in a loop or like Dave suggested if you know the values, it can set variables like a tuple.

{% set list1 = variable1.split(';') %}
The grass is {{ list1[0] }} and the boat is {{ list1[1] }}

or

{% set list1 = variable1.split(';') %}
{% for item in list1 %}
    <p>{{ item }}<p/>
{% endfor %} 

or

{% set item1, item2 = variable1.split(';') %}
The grass is {{ item1 }} and the boat is {{ item2 }}

Obfuscating the value by using the CustomFormat property, using checkbox cbEnableEndDate as the flag to indicate whether other code should ignore the value:

If dateTaskEnd > Date.FromOADate(0) Then
    dtTaskEnd.Format = DateTimePickerFormat.Custom
    dtTaskEnd.CustomFormat = "yyyy-MM-dd"
    dtTaskEnd.Value = dateTaskEnd 
    dtTaskEnd.Enabled = True
    cbEnableEndDate.Checked = True
Else
    dtTaskEnd.Format = DateTimePickerFormat.Custom
    dtTaskEnd.CustomFormat = " "
    dtTaskEnd.Value = Date.FromOADate(0)
    dtTaskEnd.Enabled = False
    cbEnableEndDate.Checked = False
End If

If you want to add a product into the array you can use:

$item['product'] = $product;

The previous answers have covered the traditional menu used in android. Their is another option you can use if you are looking for an alternative

https://github.com/AnshulBansal/Android-Pulley-Menu

Pulley menu is an alternate to the traditional Menu which allows user to select any option for an activity intuitively. The menu is revealed by dragging the screen downwards and in that gesture user can also select any of the options.

Another OpenSource signature field is https://github.com/applicius/jquery.signfield/ , registered jQuery plugin using Sketch.js .

Use WindowStyle="SingleBorderWindow" , this will hide max and min button from WPF Window.

-XX:PermSize -XX:MaxPermSize are used to set size for Permanent Generation.

Permanent Generation: The Permanent Generation is where class files are kept. These are the result of compiled classes and JSP pages. If this space is full, it triggers a Full Garbage Collection. If the Full Garbage Collection cannot clean out old unreferenced classes and there is no room left to expand the Permanent Space, an Out-of- Memory error (OOME) is thrown and the JVM will crash.

It's crucial for code obfuscation, like this:

Create your own confirm box:

<div id="confirmBox">
    <div class="message"></div>
    <span class="yes">Yes</span>
    <span class="no">No</span>
</div>

Create your own confirm() method:

function doConfirm(msg, yesFn, noFn)
{
    var confirmBox = $("#confirmBox");
    confirmBox.find(".message").text(msg);
    confirmBox.find(".yes,.no").unbind().click(function()
    {
        confirmBox.hide();
    });
    confirmBox.find(".yes").click(yesFn);
    confirmBox.find(".no").click(noFn);
    confirmBox.show();
}

Call it by your code:

doConfirm("Are you sure?", function yes()
{
    form.submit();
}, function no()
{
    // do nothing
});

You'll need to add CSS to style and position your confirm box appropriately.

Several connectors are configured, and each connector has an optional "address" attribute where you can set the IP address.

1. Edit tomcat/conf/server.xml.
2. Specify a bind address for that connector:

Are you using position: relative?

Try to set position: relative and then z-index because you want this div has a z-index in relation with other div.

By the way, your browser is important to check if it working or not. Neither IE or Firefox is a good one.

The below can be useful to access a dict keyed by abbreviations:

>>> from nltk.data import load
>>> tagdict = load('help/tagsets/upenn_tagset.pickle')
>>> tagdict['NN'][0]
'noun, common, singular or mass'
>>> tagdict.keys()
['PRP$', 'VBG', 'VBD', '``', 'VBN', ',', "''", 'VBP', 'WDT', ...

"Rounded" down as in your example. This will return a varchar value of the date.

DECLARE @date As DateTime2
SET @date = '2007-09-22 15:07:38.850'

SELECT CONVERT(VARCHAR(16), @date, 120) --2007-09-22 15:07
SELECT CONVERT(VARCHAR(13), @date, 120) --2007-09-22 15

For Bootstrap 3, you would need to use a custom wrapper and set its width to 100%.

.container-full {
  margin: 0 auto;
  width: 100%;
}

Here is a working example on Bootply

If you prefer not to add a custom class, you can acheive a very wide layout (not 100%) by wrapping everything inside a col-lg-12 (wide layout demo)

Update for Bootstrap 3.1

The container-fluid class has returned in Bootstrap 3.1, so this can be used to create a full width layout (no additional CSS required)..

Timeit has two big flaws: it doesn't return the return value of the function, and it uses eval, which requires passing in extra setup code for imports. This solves both problems simply and elegantly:

def timed(f):
  start = time.time()
  ret = f()
  elapsed = time.time() - start
  return ret, elapsed

timed(lambda: database.foo.execute('select count(*) from source.apachelog'))
(<sqlalchemy.engine.result.ResultProxy object at 0x7fd6c20fc690>, 4.07547402381897)

Easy solution if you don't want to code manually using Google Sheets Power Tools:

1. Install Power Tools through the Add-ons panel (Add-ons -> Get add-ons)
2. From the Power Tools sidebar click on the S button and within that menu click on the "Sum by Color" menu item
3. Select the "Pattern cell" with the color markup you want to search for
4. Select the "Source range" for the cells you want to count
5. Use function should be set to "COUNTA"
6. Press "Insert function" and you're done :)

Everyone of these answers has one thing in common: they all store dates as a single value (usually a string).

Another option is to take advantage of the inherent structure of JSON, and represent a date as list of numbers:

{ "name":"Nick",
  "birthdate":[1968,6,9] }

Of course, you would have to make sure both ends of the conversation agree on the format (year, month, day), and which fields are meant to be dates,... but it has the advantage of completely avoiding the issue of date-to-string conversion. It's all numbers -- no strings at all. Also, using the order: year, month, day also allows proper sorting by date.

Just thinking outside the box here -- a JSON date doesn't have to be stored as a string.

Another bonus to doing it this way is that you can easily (and efficiently) select all records for a given year or month by leveraging the way CouchDB handles queries on array values.

Try this

$("div#date").text().trim().replace(/\W/g,'/');

With base at TLSv1.2 ALERT: fatal, handshake_failure I obtained after debug with this thread previos answer

-Djavax.net.debug=all

I went to https://www.ssllabs.com/and observed that the web server required a SSLv3 connection deprecate at june 2015, and deprecated at JDKu31 Release notes

I edited the ${java_home}/jre/lib/security/java.security at the line

jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, DH keySize < 1024,
EC keySize < 224, 3DES_EDE_CBC, anon, NULL

to

jdk.tls.disabledAlgorithms= RC4, DES, MD5withRSA, DH keySize < 1024,
EC keySize < 224, 3DES_EDE_CBC, anon, NULL

As a final step I got this error

sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target [javax.net.ssl.SSLHandshakeException]

I fixed this intalling the cert with the java keytool, following this answer PKIX path building failed” and “unable to find valid certification path to requested target”

If you are looking for a handy way to test the equality of two collections, you can use org.apache.commons.collections.CollectionUtils.isEqualCollection, which compares two collections regardless of the ordering.

Programmatically, Swift

label.lineBreakMode = NSLineBreakMode.byWordWrapping
label.titleView.numberOfLines = 2

I use Visual Studio 2013 Professional.

• Place your cursor at the line of an instance variable.
  
  
  
  
• Press combine keys Ctrl + R, Ctrl + E, or click the right mouse button. Choose context menu Refactor → Encapsulate Field..., and then press OK.
  
  
  
  
• In Preview Reference Changes - Encapsulate Field dialog, press button Apply.
  
  
  
  
• This is result:
  
  

You also place the cursor for choosing a property. Use menu Edit → Refactor → Encapsulate Field...

• Other information:

  Since C# 3.0 (November 19th 2007), we can use auto-implemented properties (this is merely syntactic sugar).

  And

  private int productID;
  
  public int ProductID
  {
      get { return productID; }
      set { productID = value; }
  }
  

  becomes

  public int ProductID { get; set; }
  

A single & (not double &&) is enough or as the top answer suggests you can use 'and'. I also found this in pandas

cities['Is wide and has saint name'] = (cities['Population'] > 1000000) 
& cities['City name'].apply(lambda name: name.startswith('San'))

if we replace the "&" with "and", it won't work.
