Late to the party, but this might be of interest for people looking to add custom fonts to their ggplots inside a shiny app on shinyapps.io.

You can:

1. Place custom font in www directory: e.g. IndieFlower.ttf from here
2. Follow the steps from here

This leads to the following upper section inside the app.R file:

dir.create('~/.fonts')
file.copy("www/IndieFlower.ttf", "~/.fonts")
system('fc-cache -f ~/.fonts')

A full example app can be found here.

By publishing your whole node_modules folder you are deploying far more files than you will actually need in production.

Instead, use a task runner as part of your build process to package up those files you require, and deploy them to your wwwroot folder. This will also allow you to concat and minify your assets at the same time, rather than having to serve each individual library separately.

You can then also completely remove the FileServer configuration and rely on UseStaticFiles instead.

Currently, gulp is the VS task runner of choice. Add a gulpfile.js to the root of your project, and configure it to process your static files on publish.

For example, you can add the following scripts section to your project.json:

 "scripts": {
    "prepublish": [ "npm install", "bower install", "gulp clean", "gulp min" ]
  },

Which would work with the following gulpfile (the default when scaffolding with yo):

/// <binding Clean='clean'/>
"use strict";

var gulp = require("gulp"),
    rimraf = require("rimraf"),
    concat = require("gulp-concat"),
    cssmin = require("gulp-cssmin"),
    uglify = require("gulp-uglify");

var webroot = "./wwwroot/";

var paths = {
    js: webroot + "js/**/*.js",
    minJs: webroot + "js/**/*.min.js",
    css: webroot + "css/**/*.css",
    minCss: webroot + "css/**/*.min.css",
    concatJsDest: webroot + "js/site.min.js",
    concatCssDest: webroot + "css/site.min.css"
};

gulp.task("clean:js", function (cb) {
    rimraf(paths.concatJsDest, cb);
});

gulp.task("clean:css", function (cb) {
    rimraf(paths.concatCssDest, cb);
});

gulp.task("clean", ["clean:js", "clean:css"]);

gulp.task("min:js", function () {
    return gulp.src([paths.js, "!" + paths.minJs], { base: "." })
        .pipe(concat(paths.concatJsDest))
        .pipe(uglify())
        .pipe(gulp.dest("."));
});

gulp.task("min:css", function () {
    return gulp.src([paths.css, "!" + paths.minCss])
        .pipe(concat(paths.concatCssDest))
        .pipe(cssmin())
        .pipe(gulp.dest("."));
});

gulp.task("min", ["min:js", "min:css"]);

If you want or need to work with a Java array then you can always use the java.util.Arrays utility classes' static asList() method to convert your array to a List.

Something along those lines should work.

String mStringArray[] = { "String1", "String2" };

JSONArray mJSONArray = new JSONArray(Arrays.asList(mStringArray));

Beware that code is written offhand so consider it pseudo-code.

You can have 2 diffent problems with lists :
1) If you do a modification within an iteration even though in a mono thread environment, you will have ConcurrentModificationException like in this following example :

List<String> list = new ArrayList<String>();
for (int i=0;i<5;i++)
   list.add("Hello "+i);

for(String msg:list)
   list.remove(msg);

So, to avoid this problem, you can do :

for(int i=list.size()-1;i>=0;i--)
   list.remove(i);

2)The second problem could be multi threading environment. As mentioned above, you can use synchronized(list) to avoid exceptions.

Can I just ask about the long term need for this facility - is it for debuging purposes?

If so, then you may want to consider using a proper debugger, such as the one found in Visual Studio, as this allows you to step through the procedure in a more controlled way, and avoids having to constantly add/remove PRINT statement from the procedure.

Just my opinion, but I prefer the debugger approach - for code and databases.

I prefer to put the variable on the inside to give an extra hint that the code is validating my variable is between a range values

if (500 < size && size < 600) { doStuff(); }

The proper interval to get one second is 1000. The Interval property is the time between ticks in milliseconds:

MSDN: Timer.Interval Property

So, it's not the interval that you set that is wrong. Check the rest of your code for something like changing the interval of the timer, or binding the Tick event multiple times.

$date = strtotime(date("Y-m-d", strtotime($date)) . " +1 day");

Or, simplier:

date("Y-m-d H:i:s", time()+((60*60)*24));

Well, getting full path is not possible but we can have a temporary path.

Try This:

It'll give you a temporary path not the accurate path, you can use this script if you want to show selected images as in this jsfiddle example(Try it by selectng images as well as other files):-

JSFIDDLE

Here is the code :-

HTML:-

<input type="file" id="i_file" value=""> 
<input type="button" id="i_submit" value="Submit">
    <br>
<img src="" width="200" style="display:none;" />
        <br>
<div id="disp_tmp_path"></div>

JS:-

$('#i_file').change( function(event) {
var tmppath = URL.createObjectURL(event.target.files[0]);
    $("img").fadeIn("fast").attr('src',URL.createObjectURL(event.target.files[0]));

    $("#disp_tmp_path").html("Temporary Path(Copy it and try pasting it in browser address bar) --> <strong>["+tmppath+"]</strong>");
});

Its not exactly what you were looking for, but may be it can help you somewhere.

For all php version

if ((function_exists('session_status') 
  && session_status() !== PHP_SESSION_ACTIVE) || !session_id()) {
  session_start();
}

I tried alot of the suggestions made in this thread and on other pages but no solution worked 100% in every browsers.

So I experimented quite some time and came up with this. A complete solution for Bootstrap Equal Height columns with the help of flexbox with only 1 class. This works in all major browsers IE10+.

CSS:

.row.equal-cols {
  display: -webkit-flex;
  display: -ms-flexbox;
  display: flex;
  -webkit-flex-wrap: wrap;
  -ms-flex-wrap: wrap;
  flex-wrap: wrap;
}

.row.equal-cols:before,
.row.equal-cols:after {
  display: block;
}

.row.equal-cols > [class*='col-'] {
  display: -webkit-flex;
  display: -ms-flexbox;
  display: flex;
  -webkit-flex-direction: column;
  -ms-flex-direction: column;
  flex-direction: column;
}

.row.equal-cols > [class*='col-'] > * {
  -webkit-flex: 1 1 auto;
  -ms-flex: 1 1 auto;
  flex: 1 1 auto; 
}

HTML:

<div class="container">
  <div class="row equal-cols">
    <div class="col-sm-4">
      <div class="content"></div>
    </div>
    <div class="col-sm-4">
      <div class="content"></div>
    </div>
    <div class="col-sm-4">
      <div class="content"></div>
    </div>
  </div>
</div>

To support even more versions of IE you can, for example, use https://github.com/liabru/jquery-match-height and target all child columns of .equal-cols. Like this:

// Create a check for IE9 (or any other specific browser).
if(IE9) {
  $(".row.equal-cols > [class*='col-']").matchHeight();
}

Without this polyfill the columns will behave as usual Bootstrap columns so which is a quite good fallback.

Python is only a language, to get GET and POST data, you need a web framework or toolkit written in Python. Django is one, as Charlie points out, the cgi and urllib standard modules are others. Also available are Turbogears, Pylons, CherryPy, web.py, mod_python, fastcgi, etc, etc.

In Django, your view functions receive a request argument which has request.GET and request.POST. Other frameworks will do it differently.

If you have date object like

var date = new Date('2017/12/03');

then there is inbuilt method in javascript for getting date in milliseconds format which is valueOf()

date.valueOf(); //1512239400000 in milliseconds format

You don't want to stretch the span in height?
You have the possiblity to affect one or more flex-items to don't stretch the full height of the container.

To affect all flex-items of the container, choose this:
You have to set align-items: flex-start; to div and all flex-items of this container get the height of their content.

div {_x000D_
  align-items: flex-start;_x000D_
  background: tan;_x000D_
  display: flex;_x000D_
  height: 200px;_x000D_
}_x000D_
span {_x000D_
  background: red;_x000D_
}

<div>_x000D_
  <span>This is some text.</span>_x000D_
</div>

To affect only a single flex-item, choose this:
If you want to unstretch a single flex-item on the container, you have to set align-self: flex-start; to this flex-item. All other flex-items of the container aren't affected.

div {_x000D_
  display: flex;_x000D_
  height: 200px;_x000D_
  background: tan;_x000D_
}_x000D_
span.only {_x000D_
  background: red;_x000D_
  align-self:flex-start;_x000D_
}_x000D_
span {_x000D_
    background:green;_x000D_
}

<div>_x000D_
  <span class="only">This is some text.</span>_x000D_
  <span>This is more text.</span>_x000D_
</div>

Why is this happening to the span?
The default value of the property align-items is stretch. This is the reason why the span fill the height of the div.

Difference between baseline and flex-start?
If you have some text on the flex-items, with different font-sizes, you can use the baseline of the first line to place the flex-item vertically. A flex-item with a smaller font-size have some space between the container and itself at top. With flex-start the flex-item will be set to the top of the container (without space).

div {_x000D_
  align-items: baseline;_x000D_
  background: tan;_x000D_
  display: flex;_x000D_
  height: 200px;_x000D_
}_x000D_
span {_x000D_
  background: red;_x000D_
}_x000D_
span.fontsize {_x000D_
  font-size:2em;_x000D_
}

<div>_x000D_
  <span class="fontsize">This is some text.</span>_x000D_
  <span>This is more text.</span>_x000D_
</div>

You can find more information about the difference between baseline and flex-start here:
What's the difference between flex-start and baseline?

Use the super() function:

class Foo(Bar):
    def baz(self, arg):
        return super().baz(arg)

For Python < 3, you must explicitly opt in to using new-style classes and use:

class Foo(Bar):
    def baz(self, arg):
        return super(Foo, self).baz(arg)

By default, every Object in Java has the toString() method which outputs the ObjectType@HashCode.

If you want more meaningfull information then you need to override the toString() method in your class.

public class Person {
  private String name;

  // constructor and getter/setter omitted

  // overridding toString() to print name
  public String toString(){
     return name;  
  }
}

Now when you print the person object using System.out.prtinln(personObj); it will print the name of the person instead of the classname and hashcode.

In your second case when you are trying to print the array, it prints [Lcom.foo.Person;@28a418fc the Array type and it's hashcode.

If you want to print the person names, there are many ways.

You could write your own function that iterates each person and prints

void printPersonArray(Person[] persons){
    for(Person person: persons){
        System.out.println(person);
    }
}

You could print it using Arrays.toString(). This seems the simplest to me.

 System.out.println(Arrays.toString(persons));
 System.out.println(Arrays.deepToString(persons));  // for nested arrays  

You could print it the java 8 way (using streams and method reference).

 Arrays.stream(persons).forEach(System.out::println);

There might be other ways as well. Hope this helps. :)

The window.open will open url in new browser Tab

The window.location.href will open url in current Tab (instead you can use location)

Here is example fiddle (in SO snippets window.open doesn't work)

var url = 'https://example.com';_x000D_
_x000D_
function go1() { window.open(url) }_x000D_
_x000D_
function go2() { window.location.href = url }_x000D_
_x000D_
function go3() { location = url }

<div>Go by:</div>_x000D_
<button onclick="go1()">window.open</button>_x000D_
<button onclick="go2()">window.location.href</button>_x000D_
<button onclick="go3()">location</button>

First, please check you have include eclipse gradle plugin. apply plugin : 'eclipse' Then go to your project directory in Terminal. Type gradle clean and then gradle eclipse. Then go to project in eclipse and refresh the project.

This should work, but there is a little trick. After you enter the formula, you need to hold down Ctrl+Shift while you press Enter. When you do, you'll see that the formula bar has curly-braces around your formula. This is called an array formula.

For example, if the Months are in cells A2:A100 and the amounts are in cells B2:B100, your formula would look like {=SUM(If(A2:A100="January",B2:B100))}. You don't actually type the curly-braces though.

You could also do something like =SUM((A2:A100="January")*B2:B100). You'd still need to use the trick to get it to work correctly.

This line is your problem:

litersOfPetrol = Float.parseFloat(df.format(litersOfPetrol));

There you formatted your float to string as you wanted, but but then that string got transformed again to a float, and then what you printed in stdout was your float that got a standard formatting. Take a look at this code

import java.text.DecimalFormat;

String stringLitersOfPetrol = "123.00";
System.out.println("string liters of petrol putting in preferences is "+stringLitersOfPetrol);
Float litersOfPetrol=Float.parseFloat(stringLitersOfPetrol);
DecimalFormat df = new DecimalFormat("0.00");
df.setMaximumFractionDigits(2);
stringLitersOfPetrol = df.format(litersOfPetrol);
System.out.println("liters of petrol before putting in editor : "+stringLitersOfPetrol);

And by the way, when you want to use decimals, forget the existence of double and float as others suggested and just use BigDecimal object, it will save you a lot of headache.

The Maximum execution time of 30 seconds exceeded error is not related to Laravel but rather your PHP configuration.

Here is how you can fix it. The setting you will need to change is max_execution_time.

;;;;;;;;;;;;;;;;;;;
; Resource Limits ;
;;;;;;;;;;;;;;;;;;;

max_execution_time = 30     ; Maximum execution time of each script, in seconds
max_input_time = 60 ; Maximum amount of time each script may spend parsing request data
memory_limit = 8M      ; Maximum amount of memory a script may consume (8MB)

You can change the max_execution_time to 300 seconds like max_execution_time = 300

You can find the path of your PHP configuration file in the output of the phpinfo function in the Loaded Configuration File section.

You can use map function

{Object.keys(tifs).map(key => (
    <option value={key}>{tifs[key]}</option>
))}

git checkout -b NEW_BRANCH_NAME COMMIT_ID

This will create a new branch called 'NEW_BRANCH_NAME' and check it out.

("check out" means "to switch to the branch")

git branch NEW_BRANCH_NAME COMMIT_ID

This just creates the new branch without checking it out.

in the comments many people seem to prefer doing this in two steps. here's how to do so in two steps:

git checkout COMMIT_ID
# you are now in the "detached head" state
git checkout -b NEW_BRANCH_NAME

Open MySQL console and type SET PASSWORD = 'your password'; and then press ENTER Key which will set your defined password for user root.

You can only write SET PASSWORD = ''; which will set password as blank for root user.

Don't do this! You're opening your machine to attacks. Instead run a local server. It's as easy as opening a shell/terminal/commandline and typing

cd path/to/files
python -m SimpleHTTPServer

Then pointing your browser to

http://localhost:8000

If you find it's too slow consider this solution

Almost 5 years later, I think my answer can reduce a little bit the hard work of many people.

Update an element in the DOM with the HTML from the one from the ajax call can be achieved that way

$('#submitform').click(function() {
     $.ajax({
     url: "getinfo.asp",
     data: {
         txtsearch: $('#appendedInputButton').val()
     },
     type: "GET",
     dataType : "html",
     success: function (data){
         $('#showresults').html($('#showresults',data).html());
         // similar to $(data).find('#showresults')
     },
});

or with replaceWith()

// codes

success: function (data){
   $('#showresults').replaceWith($('#showresults',data));
},

It seems you can just display both dfs using a comma in between in display. I noticed this on some notebooks on github. This code is from Jake VanderPlas's notebook.

class display(object):
    """Display HTML representation of multiple objects"""
    template = """<div style="float: left; padding: 10px;">
    <p style='font-family:"Courier New", Courier, monospace'>{0}</p>{1}
    </div>"""
    def __init__(self, *args):
        self.args = args

    def _repr_html_(self):
        return '\n'.join(self.template.format(a, eval(a)._repr_html_())
                     for a in self.args)

    def __repr__(self):
        return '\n\n'.join(a + '\n' + repr(eval(a))
                       for a in self.args)

display('df', "df2")

Add this:

$(document).ready(function(){
    $(document).on('shown.bs.modal','.modal', function () {
         // DO EVENTS
    });
});

Here is code to get line number and column position

function getLineNumber(tArea) {

    return tArea.value.substr(0, tArea.selectionStart).split("\n").length;
}

function getCursorPos() {
    var me = $("textarea[name='documenttext']")[0];
    var el = $(me).get(0);
    var pos = 0;
    if ('selectionStart' in el) {
        pos = el.selectionStart;
    } else if ('selection' in document) {
        el.focus();
        var Sel = document.selection.createRange();
        var SelLength = document.selection.createRange().text.length;
        Sel.moveStart('character', -el.value.length);
        pos = Sel.text.length - SelLength;
    }
    var ret = pos - prevLine(me);
    alert(ret);

    return ret; 
}

function prevLine(me) {
    var lineArr = me.value.substr(0, me.selectionStart).split("\n");

    var numChars = 0;

    for (var i = 0; i < lineArr.length-1; i++) {
        numChars += lineArr[i].length+1;
    }

    return numChars;
}

tArea is the text area DOM element

In Bootstrap 5, which doesn't use jQuery, you can do this:

const btn = document.createElement('button');
btn.innerHTML = 'Click me';
btn.dataset['toggle'] = 'tooltip';
btn.dataset['placement'] = 'top';
btn.title = 'Your Tooltip Here';
new bootstrap.Tooltip(btn);

document.getElementById('parent').appendChild(btn);

I know this is a very old question, but I created some extension methods that might be useful:

    public static void ForEach<T, U>(this Dictionary<T, U> d, Action<KeyValuePair<T, U>> a)
    {
        foreach (KeyValuePair<T, U> p in d) { a(p); }
    }

    public static void ForEach<T, U>(this Dictionary<T, U>.KeyCollection k, Action<T> a)
    {
        foreach (T t in k) { a(t); }
    }

    public static void ForEach<T, U>(this Dictionary<T, U>.ValueCollection v, Action<U> a)
    {
        foreach (U u in v) { a(u); }
    }

This way I can write code like this:

myDictionary.ForEach(pair => Console.Write($"key: {pair.Key}, value: {pair.Value}"));
myDictionary.Keys.ForEach(key => Console.Write(key););
myDictionary.Values.ForEach(value => Console.Write(value););

As per comments, First you need to install an instance of SQL Server if you don't already have one - https://msdn.microsoft.com/en-us/library/ms143219.aspx

Once this is installed you must connect to this instance (server) and then you can create a database here - https://msdn.microsoft.com/en-US/library/ms186312.aspx

If anyone gets scrollHeight as undefined, then select elements' 1st subelement: mob_top_menu[0].scrollHeight

The most important thing is to avoid creating a problem, so I believe that you should use a direct relation to avoid having a cycle.

As @markmywords said, #include "fritzl.h".

Finally I have to say recheck your data structure. Maybe something is going wrong over there (maybe a bidirectional linked list solves your problem).

three different approaches:

1. Classic client/server approach: don't put any database in the shops; simply have the applications access your server. Of course it's better if you set a VPN, but simply wrapping the connection in SSL or ssh is reasonable. Pro: it's the way databases were originally thought. Con: if you have high latency, complex operations could get slow, you might have to use stored procedures to reduce the number of round trips.

2. replicated master/master: as @Book Of Zeus suggested. Cons: somewhat more complex to setup (especially if you have several shops), breaking in any shop machine could potentially compromise the whole system. Pros: better responsivity as read operations are totally local and write operations are propagated asynchronously.

3. offline operations + sync step: do all work locally and from time to time (might be once an hour, daily, weekly, whatever) write a summary with all new/modified records from the last sync operation and send to the server. Pros: can work without network, fast, easy to check (if the summary is readable). Cons: you don't have real-time information.

At the package stage, the plugin allows configuration of the imported file names via file mapping:

maven-ear-plugin

http://maven.apache.org/plugins/maven-ear-plugin/examples/customize-file-name-mapping.html

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-ear-plugin</artifactId>
    <version>2.7</version>
    <configuration>
       [...]
        <fileNameMapping>full</fileNameMapping>
    </configuration>
</plugin>

http://maven.apache.org/plugins/maven-war-plugin/war-mojo.html#outputFileNameMapping

If you have configured your version to be 'testing' via a profile or something, this would work for a war package:

maven-war-plugin

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <version>2.2</version>
    <configuration>
        <encoding>UTF-8</encoding>                        
        <outputFileNameMapping>@{groupId}@-@{artifactId}@-@{baseVersion}@@{dashClassifier?}@.@{extension}@</outputFileNameMapping>
    </configuration>
</plugin>

I've seen occasional problems with Eclipse forgetting that built-in classes (including Object and String) exist. The way I've resolved them is to:

• On the Project menu, turn off "Build Automatically"
• Quit and restart Eclipse
• On the Project menu, choose "Clean…" and clean all projects
• Turn "Build Automatically" back on and let it rebuild everything.

This seems to make Eclipse forget whatever incorrect cached information it had about the available classes.

The quickest and easiest way I've found to Json-ify POJOs is to use the Gson library. This blog post gives a quick overview of using the library.

From W3 web site Common HTML entities used for typography

For the sake of portability, Unicode entity references should be reserved for use in documents certain to be written in the UTF-8 or UTF-16 character sets. In all other cases, the alphanumeric references should be used.

If you want to dynamically allocate arrays, you can use malloc from stdlib.h.

If you want to allocate an array of 100 elements using your words struct, try the following:

words* array = (words*)malloc(sizeof(words) * 100);

The size of the memory that you want to allocate is passed into malloc and then it will return a pointer of type void (void*). In most cases you'll probably want to cast it to the pointer type you desire, which in this case is words*.

The sizeof keyword is used here to find out the size of the words struct, then that size is multiplied by the number of elements you want to allocate.

Once you are done, be sure to use free() to free up the heap memory you used in order to prevent memory leaks:

free(array);

If you want to change the size of the allocated array, you can try to use realloc as others have mentioned, but keep in mind that if you do many reallocs you may end up fragmenting the memory. If you want to dynamically resize the array in order to keep a low memory footprint for your program, it may be better to not do too many reallocs.

In my project I used Oracle 12c and java. The paging code looks like this:

 public public List<Map<String, Object>> getAllProductOfferWithPagination(int pageNo, int pageElementSize, Long productOfferId, String productOfferName) {
    try {

        if(pageNo==1){
            //do nothing
        } else{
            pageNo=(pageNo-1)*pageElementSize+1;
        }
        System.out.println("algo pageNo: " + pageNo +"  pageElementSize: "+ pageElementSize+"  productOfferId: "+ productOfferId+"  productOfferName: "+ productOfferName);

        String sql = "SELECT * FROM ( SELECT * FROM product_offer po WHERE po.deleted=0 AND (po.product_offer_id=? OR po.product_offer_name LIKE ? )" +
             " ORDER BY po.PRODUCT_OFFER_ID asc) foo OFFSET ? ROWS FETCH NEXT ? ROWS ONLY ";

       return jdbcTemplate.queryForList(sql,new Object[] {productOfferId,"%"+productOfferName+"%",pageNo-1, pageElementSize});

    } catch (Exception e) {
        System.out.println(e);
        e.printStackTrace();
        return null;
    }

A bit late to the party, but this is what worked for me:

>>> import sys
>>> sys.path.insert(0, '')

Apparently, if there is an empty string, Python knows that it should look in the current directory. I did not have the empty string in sys.path, which caused this error.

Another good solution is to use outline instead of border. It adds a border without affecting the box model. This works on IE8+, Chrome, Firefox, Opera, Safari.

Most important

Keep in mind that relative URLs are resolved from the URL of your stylesheet.

So it will work if folder images is inside the stylesheets folder.

From you description you would need to change it to either

url("../images/plaid.jpg")

or

url("/images/plaid.jpg") 

Additional 1

Also you cannot have no selector..

CSS is applied through selectors..

Additional 2

You should use either the shorthand background to pass multiple values like this

background: url("../images/plaid.jpg") no-repeat;

or the verbose syntax of specifying each property on its own

background-image: url("../images/plaid.jpg");
background-repeat:no-repeat;

Another solution is the one described here at the end of this post by "enlian": http://springinpractice.com/2013/10/07/handling-json-error-object-responses-with-springs-resttemplate

try{
     restTemplate.exchange(...)
} catch(HttpStatusCodeException e){
     String errorpayload = e.getResponseBodyAsString();
     //do whatever you want
} catch(RestClientException e){
     //no response payload, tell the user sth else 
}

We can use dplyr to select only numeric columns and purr to get sum for all columns. (can be used to get what ever value for all columns, such as mean, min, max, etc. )

library("dplyr")
library("purrr")

people %>%
    select_if(is.numeric) %>%
    map_dbl(sum)

Or another easy way by only using dplyr

library("dplyr")
people %>%
    summarize_if(is.numeric, sum, na.rm=TRUE)

main_list=[]
list_1=["a", "b", "c", "d", "e"]
list_2=["a", "f", "c", "m"]

for i in list_2:
    if i not in list_1:
        main_list.append(i)

print(main_list)

output:

['f', 'm']

mysql_query("SHOW TABLES FROM yourDB");
//> loop thru results and see if it exists
//> in this way with only one query one can check easly more table 

or mysql_query("SHOW TABLES LIKE 'tblname'");

Don't use mysql_list_tables(); because it's deprecated

Here is a simple way to implement ls command using c. To run use for example ./xls /tmp

    #include<stdio.h>
    #include <dirent.h>
    void main(int argc,char *argv[])
    {
   DIR *dir;
   struct dirent *dent;
   dir = opendir(argv[1]);   

   if(dir!=NULL)
      {
   while((dent=readdir(dir))!=NULL)
                    {
        if((strcmp(dent->d_name,".")==0 || strcmp(dent->d_name,"..")==0 || (*dent->d_name) == '.' ))
            {
            }
       else
              {
        printf(dent->d_name);
        printf("\n");
              }
                    }
       }
       close(dir);
     }

Developer point of view
If you are in development mode (like in the original question), the best approach is to disable caching in the browser via HTML meta tags. To make this approach universal you must insert at least three meta tags as shown below.

<meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" />
<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Expires" content="0" />

In this way, you as a developer, only need to refresh the page to see the changes. But do not forget to comment that code when in production, after all caching is a good thing for your clients.

Production Mode
Because in production you will allow caching and your clients do not need to know how to force a full reload or any other trick, you must warranty the browser will load the new file. And yes, in this case, the best approach I know is to change the name of the file.

There are two ways to do this.

1. providing the SHA of the commit you want to see to git log

git log -p a2c25061

Where -p is short for patch

2. use git show

git show a2c25061

The output for both commands will be:

• the commit
• the author
• the date
• the commit message
• the patch information

I haven't needed to turn on anti-alias because it's on by default but I have needed to turn it off. And if it can be turned off it can also be turned on.

ctx.imageSmoothingEnabled = true;

I usually shut it off when I'm working on my canvas rpg so when I zoom in the images don't look blurry.

Simple use if you want How to execute threads alternatively :-

public class MyThread {
    public static void main(String[] args) {
        final Object lock = new Object();
        new Thread(() -> {
            try {
                synchronized (lock) {
                    for (int i = 0; i <= 5; i++) {
                        System.out.println(Thread.currentThread().getName() + ":" + "A");
                        lock.notify();
                        lock.wait();
                    }
                }
            } catch (Exception e) {}
        }, "T1").start();

        new Thread(() -> {
            try {

you can use the shell (bash/ksh).

$ replace="test"
$ echo ${var//12345678/$replace}

Try using:

Console.WriteLine()

The call to Debug.WriteLine will only be made during when DEBUG is defined.

Other suggestions are to use: Trace.WriteLine as well, but I haven't tried this.

There is also an option (not sure if Visual Studio 2008 has it), but you can still Use Debug.WriteLine when you run the test with Test With Debuggeroption in the IDE.

Assuming you have your hidden input in a jQuery object $myHidden, you then use JavaScript (not jQuery) to get the part after ?:

var myVal = $myHidden.val ();
var tmp = myVal.substr ( myVal.indexOf ( '?' ) + 1 ); // tmp now contains whatever is after ?

Start up R in a fresh session and paste this in:

library(ggplot2)

df <- structure(list(year = c(1, 2, 3, 4), pollution = structure(c(346.82, 
134.308821199349, 130.430379885892, 88.275457392443), .Dim = 4L, .Dimnames = list(
    c("1999", "2002", "2005", "2008")))), .Names = c("year", 
"pollution"), row.names = c(NA, -4L), class = "data.frame")

df[] <- lapply(df, as.numeric) # make all columns numeric

ggplot(df, aes(year, pollution)) +
           geom_point() +
           geom_line() +
           labs(x = "Year", 
                y = "Particulate matter emissions (tons)", 
                title = "Motor vehicle emissions in Baltimore")

Generally

Your pkl file is, in fact, a serialized pickle file, which means it has been dumped using Python's pickle module.

To un-pickle the data you can:

import pickle


with open('serialized.pkl', 'rb') as f:
    data = pickle.load(f)

For the MNIST data set

Note gzip is only needed if the file is compressed:

import gzip
import pickle


with gzip.open('mnist.pkl.gz', 'rb') as f:
    train_set, valid_set, test_set = pickle.load(f)

Where each set can be further divided (i.e. for the training set):

train_x, train_y = train_set

Those would be the inputs (digits) and outputs (labels) of your sets.

If you want to display the digits:

import matplotlib.cm as cm
import matplotlib.pyplot as plt


plt.imshow(train_x[0].reshape((28, 28)), cmap=cm.Greys_r)
plt.show()

The other alternative would be to look at the original data:

http://yann.lecun.com/exdb/mnist/

But that will be harder, as you'll need to create a program to read the binary data in those files. So I recommend you to use Python, and load the data with pickle. As you've seen, it's very easy. ;-)

For an attribute value that needs to be interpolated in a directive that is not using an isolated scope, e.g.,

<input my-directive value="{{1+1}}">

use Attributes' method $observe:

myApp.directive('myDirective', function () {
  return function (scope, element, attr) {
    attr.$observe('value', function(actual_value) {
      element.val("value = "+ actual_value);
    })
 }
});

From the directive page,

observing interpolated attributes: Use $observe to observe the value changes of attributes that contain interpolation (e.g. src="{{bar}}"). Not only is this very efficient but it's also the only way to easily get the actual value because during the linking phase the interpolation hasn't been evaluated yet and so the value is at this time set to undefined.

If the attribute value is just a constant, e.g.,

<input my-directive value="123">

you can use $eval if the value is a number or boolean, and you want the correct type:

return function (scope, element, attr) {
   var number = scope.$eval(attr.value);
   console.log(number, number + 1);
});

If the attribute value is a string constant, or you want the value to be string type in your directive, you can access it directly:

return function (scope, element, attr) {
   var str = attr.value;
   console.log(str, str + " more");
});

In your case, however, since you want to support interpolated values and constants, use $observe.

Apart from the methods mentioned earlier. You can also use the command del to remove multiple variables

del variable1,variable2

Also, you can do this:

(this.DNATranscriber as any)[character];

Edit.

It's HIGHLY recommended that you cast the object with the proper type instead of any. Casting an object as any only help you to avoid type errors when compiling typescript but it doesn't help you to keep your code type-safe.

E.g.

interface DNA {
    G: "C",
    C: "G",
    T: "A",
    A: "U"
}

And then you cast it like this:

(this.DNATranscriber as DNA)[character];

If your table is only 2 columns across, you can easily reach the second td with the adjacent sibling selector, which IE8 does support along with :first-child:

.editor td:first-child
{
    width: 150px; 
}

.editor td:first-child + td input,
.editor td:first-child + td textarea
{
    width: 500px;
    padding: 3px 5px 5px 5px;
    border: 1px solid #CCC; 
}

Otherwise, you'll have to use a JS selector library like jQuery, or manually add a class to the last td, as suggested by James Allardice.

You should deploy "Client Profile" instead of "Full Framework" inside a corporation mostly in one case only: you want explicitly deny some .NET features are running on the client computers. The only real case is denying of ASP.NET on the client machines of the corporation, for example, because of security reasons or the existing corporate policy.

Saving of less than 8 MB on client computer can not be a serious reason of "Client Profile" deployment in a corporation. The risk of the necessity of the deployment of the "Full Framework" later in the corporation is higher than costs of 8 MB per client.

the best solution here

class Category(var Id: Int,var Name: String)
arrayList is Category list
val selectedPositon=arrayList.map { x->x.Id }.indexOf(Category_Id)
spinner_update_categories.setSelection(selectedPositon)

You can access the index attribute of a df using df.index[i]

>> import pandas as pd
>> import numpy as np
>> df = pd.DataFrame({'a':np.arange(5), 'b':np.random.randn(5)})
   a         b
0  0  1.088998
1  1 -1.381735
2  2  0.035058
3  3 -2.273023
4  4  1.345342

>> df.index[1] ## Second index
>> df.index[-1] ## Last index

>> for i in xrange(len(df)):print df.index[i] ## Using loop

I modified the above technique which was close to what I wanted for angular and turned it into a service :-). I included ie9 because I was having some issues in my angularjs app, but could be something I'm doing, so feel free to take it out.

angular.module('myModule').service('browserDetectionService', function() {

 return {
isCompatible: function () {

  var browserInfo = navigator.userAgent;
  var browserFlags =  {};

  browserFlags.ISFF = browserInfo.indexOf('Firefox') != -1;
  browserFlags.ISOPERA = browserInfo.indexOf('Opera') != -1;
  browserFlags.ISCHROME = browserInfo.indexOf('Chrome') != -1;
  browserFlags.ISSAFARI = browserInfo.indexOf('Safari') != -1 && !browserFlags.ISCHROME;
  browserFlags.ISWEBKIT = browserInfo.indexOf('WebKit') != -1;

  browserFlags.ISIE = browserInfo.indexOf('Trident') > 0 || navigator.userAgent.indexOf('MSIE') > 0;
  browserFlags.ISIE6 = browserInfo.indexOf('MSIE 6') > 0;
  browserFlags.ISIE7 = browserInfo.indexOf('MSIE 7') > 0;
  browserFlags.ISIE8 = browserInfo.indexOf('MSIE 8') > 0;
  browserFlags.ISIE9 = browserInfo.indexOf('MSIE 9') > 0;
  browserFlags.ISIE10 = browserInfo.indexOf('MSIE 10') > 0;
  browserFlags.ISOLD = browserFlags.ISIE6 || browserFlags.ISIE7 || browserFlags.ISIE8 || browserFlags.ISIE9; // MUST be here

  browserFlags.ISIE11UP = browserInfo.indexOf('MSIE') == -1 && browserInfo.indexOf('Trident') > 0;
  browserFlags.ISIE10UP = browserFlags.ISIE10 || browserFlags.ISIE11UP;
  browserFlags.ISIE9UP = browserFlags.ISIE9 || browserFlags.ISIE10UP;

  return !browserFlags.ISOLD;
  }
};

});

  Language[] items = new Language[]{new Language("English", "En"),
                new Language("Italian", "It")};

            languagesCombo.ValueMember = "Alias";
            languagesCombo.DisplayMember = "FullName";
            languagesCombo.DataSource = items.ToList();

            languagesCombo.DropDownStyle = ComboBoxStyle.DropDownList;

 class Language
    {
        public string FullName { get; set; }
        public string Alias { get; set; }

        public Language(string fullName, string alias)
        {
            this.FullName = fullName;
            this.Alias = alias;
        }
    }

By making your drop down box "read-only" I am assuming you want to prevent user's typing in other options as opposed to being fully read-only where users cannot select a value??

If you wanted it to be fully read-only you could set the enabled property to be false.

One thing you can do is, you might have subfolders for each projects. So, install mongoose in that subfolders and require() mongoose from own folders in each sub applications. Not from the project root or from global. So one sub project, one mongoose installation and one mongoose instance.

-app_root/
--foo_app/
---db_access.js
---foo_db_connect.js
---node_modules/
----mongoose/
--bar_app/
---db_access.js
---bar_db_connect.js
---node_modules/
----mongoose/

In foo_db_connect.js

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/foo_db');
module.exports = exports = mongoose;

In bar_db_connect.js

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/bar_db');
module.exports = exports = mongoose;

In db_access.js files

var mongoose = require("./foo_db_connect.js"); // bar_db_connect.js for bar app

Now, you can access multiple databases with mongoose.

To Configure exception handling behavior per exception type you can use Middleware from NuGet packages:

• Community.AspNetCore.ExceptionHandling.NewtonsoftJson for ASP.NET Core 2.0
• Community.AspNetCore.ExceptionHandling.Mvc for ASP.NET Core 2.1+.

Code sample:

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc();

    services.AddExceptionHandlingPolicies(options =>
    {
        options.For<InitializationException>().Rethrow();

        options.For<SomeTransientException>().Retry(ro => ro.MaxRetryCount = 2).NextPolicy();

        options.For<SomeBadRequestException>()
        .Response(e => 400)
            .Headers((h, e) => h["X-MyCustomHeader"] = e.Message)
            .WithBody((req,sw, exception) =>
                {
                    byte[] array = Encoding.UTF8.GetBytes(exception.ToString());
                    return sw.WriteAsync(array, 0, array.Length);
                })
        .NextPolicy();

        // Ensure that all exception types are handled by adding handler for generic exception at the end.
        options.For<Exception>()
        .Log(lo =>
            {
                lo.EventIdFactory = (c, e) => new EventId(123, "UnhandlerException");
                lo.Category = (context, exception) => "MyCategory";
            })
        .Response(null, ResponseAlreadyStartedBehaviour.GoToNextHandler)
            .ClearCacheHeaders()
            .WithObjectResult((r, e) => new { msg = e.Message, path = r.Path })
        .Handled();
    });
}

public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
    app.UseExceptionHandlingPolicies();
    app.UseMvc();
}

If non-numeric value encountered in your code try below one. The below code is converted to float.

$PlannedAmount = ''; // empty string ''

if(!is_numeric($PlannedAmount)) {
           $PlannedAmount = floatval($PlannedAmount);
 }

 echo $PlannedAmount; //output = 0

First import your custom cell file #import "CustomCell.h" and then change the delegate method as below mentioned:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

static NSString *simpleTableIdentifier = @"CustomCell";

CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
    NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CustomCell" owner:self options:nil];
    cell = [nib objectAtIndex:0];

    [cell setSelectionStyle:UITableViewCellSelectionStyleNone];
}         

     return cell;
}

It looks like you might not have defined a start script in your package.json file or your project does not contain a server.js file.

If there is a server.js file in the root of your package, then npm will default the start command to node server.js.

https://docs.npmjs.com/misc/scripts#default-values

You could either change the name of your application script to server.js or add the following to your package.json

"scripts": {
    "start": "node your-script.js"
}

Or ... you could just run node your-script.js directly

If you want to run some custom filter logic you can create a function which takes the array element as an argument and returns true or false based on whether it should be in the search results. Then pass it to the filter instruction just like you do with the search object, for example:

JS:

$scope.filterFn = function(car)
{
    // Do some tests

    if(car.carDetails.doors > 2)
    {
        return true; // this will be listed in the results
    }

    return false; // otherwise it won't be within the results
};

HTML:

...
<article data-ng-repeat="result in results | filter:search | filter:filterFn" class="result">
...

As you can see you can chain many filters together, so adding your custom filter function doesn't force you to remove the previous filter using the search object (they will work together seamlessly).

I agree with @BeowulfOF, though for clarity I would always advocate splitting the statements so that the logic is absolutely clear, i.e.:

i++;
x += i;

or

x += i;
i++;

So my answer is if you write clear code then this should rarely matter (and if it matters then your code is probably not clear enough).

If you know your controller is unintentionally executing more than once, try a search through your files for the name of the offending controller, ex: search: MyController through all files. Likely it got copy-pasted in some other html/js file and you forgot to change it when you got to developing or using those partials/controllers. Source: I made this mistake

I prefer this one. It can be combined with other linq commands.

from item in list
let xyz = item.PropertyToChange = calcValue()
select item

Run stat -c %h folder and subtract 2 from the result. This employs only a single subprocess as opposed to the 2 (or even 3) required by most of the other solutions here (typically find plus wc).

Using sh/bash:

cnt=$((`stat -c %h folder` - 2))
echo $cnt   # 'echo' is a sh/bash builtin, not an additional process

Using csh/tcsh:

@ cnt = `stat -c %h folder` - 2
echo $cnt   # 'echo' is a csh/tcsh builtin, not an additional process

Explanation: stat -c %h folder prints the number of hardlinks to folder, and each subfolder under folder contains a ../ entry which is a hardlink back to folder. You must subtract 2 because there are two additional hardlinks in the count:

1. folder's own self-referential ./ entry, and
2. folder's parent's link to folder

just write '' in place of ' i mean two times '

Below sample code can read file line by line and write new file in UTF-8 format. Also, i am explicitly specifying Cp1252 encoding.

    public static void main(String args[]) throws IOException {

    BufferedReader br = new BufferedReader(new InputStreamReader(
            new FileInputStream("c:\\filenonUTF.txt"),
            "Cp1252"));
    String line;

    Writer out = new BufferedWriter(
            new OutputStreamWriter(new FileOutputStream(
                    "c:\\fileUTF.txt"), "UTF-8"));

    try {

        while ((line = br.readLine()) != null) {

            out.write(line);
            out.write("\n");

        }

    } finally {

        br.close();
        out.close();

    }
}

Make sure you image is a relative path such as:

@Url.Content("~/Content/images/myimage.png")

MVC4

<img src="~/Content/images/myimage.png" />

You could convert the byte[] into a Base64 string on the fly.

string base64String = Convert.ToBase64String(imageBytes);

<img src="@String.Format("data:image/png;base64,{0}", base64string)" />

You may create a new list with an input of a previous list like so:

List one = new ArrayList()
//... add data, sort, etc
List two = new ArrayList(one);

This will allow you to modify the order or what elemtents are contained independent of the first list.

Keep in mind that the two lists will contain the same objects though, so if you modify an object in List two, the same object will be modified in list one.

example:

MyObject value1 = one.get(0);
MyObject value2 = two.get(0);
value1 == value2 //true
value1.setName("hello");
value2.getName(); //returns "hello"

Edit

To avoid this you need a deep copy of each element in the list like so:

List<Torero> one = new ArrayList<Torero>();
//add elements

List<Torero> two = new Arraylist<Torero>();
for(Torero t : one){
    Torero copy = deepCopy(t);
    two.add(copy);
}

with copy like the following:

public Torero deepCopy(Torero input){
    Torero copy = new Torero();
    copy.setValue(input.getValue());//.. copy primitives, deep copy objects again

    return copy;
}

Just to extend Mark Byers's answer with an example:

import java.util.UUID;

public class RandomStringUUID {
    public static void main(String[] args) {
        UUID uuid = UUID.randomUUID();
        System.out.println("UUID=" + uuid.toString() );
    }
}

You can set the format in aspx, just add the property "DateFormatString" in your BoundField.

DataFormatString="{0:dd/MM/yyyy hh:mm:ss}"

What is row?

Either of these could be correct.

1) I assume that you capture your ajax response in a javascript variable 'row'. If that is the case, this would hold true.

var result=row.split('|');
    alert(result[2]);

otherwise

2) Use this where $(row) is a jQuery object.

var result=$(row).val().split('|');
    alert(result[2]);

[As mentioned in the other answer, you may have to use $(row).val() or $(row).text() or $(row).html() etc. depending on what $(row) is.]

$ su - postgres
$ psql
$ \du; for see the user on db
select the user that do you want be superuser and:
$ ALTER USER "user" with superuser;

Try this:

   AlertDialog.Builder builder = new AlertDialog.Builder(this);
   AlertDialog OptionDialog = builder.create();
  background.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            SetBackground();
       OptionDialog .dismiss();
        }
    });

The other solution proposed on this page are useful some versions of Cmake < 3.3.2. Here the solution for the version I am using (i.e., 3.3.2). Check the version of your Cmake by using $ cmake --version and pick the solution that fits with your needs. The cmake documentation can be found on the official page.

With CMake version 3.3.2, in order to create

#define foo

I needed to use:

add_definitions(-Dfoo)   # <--------HERE THE NEW CMAKE LINE inside CMakeLists.txt
add_executable( ....)
target_link_libraries(....)

and, in order to have a preprocessor macro definition like this other one:

#define foo=5

the line is so modified:

add_definitions(-Dfoo=5)   # <--------HERE THE NEW CMAKE LINE inside CMakeLists.txt
add_executable( ....)
target_link_libraries(....)

I found this site useful: http://www.vanseodesign.com/css/vertical-centering/ This worked for me:

HTML

<div id="parent">
    <div id="child">Content here</div>
</div>

CSS

#parent {
    padding: 5% 0;
}

#child {
    padding: 10% 0;
}

Following is worked for me

File dir = new File("E:\\test");
        ProcessBuilder pb = new ProcessBuilder("cmd.exe", "/C", "Start","test.bat");
        pb.directory(dir);
        Process p = pb.start();

I wrote an npm package called 'html-form-enhancer'. By dropping it into your HTML source, it takes over submission of forms with methods aside from GET and POST, and also adds application/json serialization.

<script type=module" src="html-form-enhancer.js"></script>

<form method="PUT">
...
</form>

1. There is no such thing as xhr.file = file;; the file object is not supposed to be attached this way.

2. xhr.send(file) doesn't send the file. You have to use the FormData object to wrap the file into a multipart/form-data post data object:

   var formData = new FormData();
   formData.append("thefile", file);
   xhr.send(formData);
   

After that, the file can be access in $_FILES['thefile'] (if you are using PHP).

Remember, MDC and Mozilla Hack demos are your best friends.

EDIT: The (2) above was incorrect. It does send the file, but it would send it as raw post data. That means you would have to parse it yourself on the server (and it's often not possible, depend on server configuration). Read how to get raw post data in PHP here.

Using scala:

import xml._
val xml = XML.loadString("<tag><nested>hello</nested></tag>")
val formatted = new PrettyPrinter(150, 2).format(xml)
println(formatted)

You can do this in Java too, if you depend on the scala-library.jar. It looks like this:

import scala.xml.*;

public class FormatXML {
    public static void main(String[] args) {
        String unformattedXml = "<tag><nested>hello</nested></tag>";
        PrettyPrinter pp = new PrettyPrinter(150, 3);
        String formatted = pp.format(XML.loadString(unformattedXml), TopScope$.MODULE$);
        System.out.println(formatted);
    }
}

The PrettyPrinter object is constructed with two ints, the first being max line length and the second being the indentation step.

The above example using sort is close, but in the case of strings simply use SearchString:

files := []string{"Test.conf", "util.go", "Makefile", "misc.go", "main.go"}
target := "Makefile"
sort.Strings(files)
i := sort.SearchStrings(files, target)
if i < len(files) && files[i] == target {
    fmt.Printf("found \"%s\" at files[%d]\n", files[i], i)
}

https://golang.org/pkg/sort/#SearchStrings

There is a better way that is safer and will not slow down your application. How Excel is set up, a cell can have either a value or a formula; the formula can not refer to its own cell. Otherwise, You end up with an infinite loop, since the new value would cause another calculation... .

Use a helper column to calculate the value based on what you put in the other cell.

For Example:

Column A is a True or False, Column B contains a monetary value, Column C contains the following formula:

=B1

Now, to calculate that column B will be highlighted yellow in a conditional format only if Column A is True and Column B is greater than Zero...

=AND(A1=True,C1>0)

You can then choose to hide column C

Select your database - Right Click - Select Properties

Select FILE in left side of page

In the OWNER box, select button which has three dots (…) in it

Now select user ‘sa and Click OK

Well, you pretty much gave yourself the answer. In your CSS give the containing element a min-width. If you have to support IE6 you can use the min-width-trick:

#container {
    min-width:800px;
    width: auto !important;
    width:800px;
}

That will effectively give you 800px min-width in IE6 and any up-to-date browsers.

Here is another approach.

class orbisius_custom_string {
    /**
     * The reverse of nl2br. Handles <br/> <br/> <br />
     * usage: orbisius_custom_string::br2nl('Your buffer goes here ...');
     * @param str $buff
     * @return str
     * @author Slavi Marinov | http://orbisius.com
     */
    public static function br2nl($buff = '') {
        $buff = preg_replace('#<br[/\s]*>#si', "\n", $buff);
        $buff = trim($buff);

        return $buff;
    }
}

If you want to use this in VBA:

For i = 1 To X
    UserForm1.Controls("Label" & i).Caption =  MySheet.Cells(i + 1, i).Value
Next

use something like:

double step = 1d / 5;

(1d is a cast to double)

There is something fundamentally wrong with what you're trying to do. Binary floating-points values do not have decimal places. You cannot meaningfully round one to a given number of decimal places, because most "round" decimal values simply cannot be represented as a binary fraction. Which is why one should never use float or double to represent money.

So if you want decimal places in your result, that result must either be a String (which you already got with the DecimalFormat), or a BigDecimal (which has a setScale() method that does exactly what you want). Otherwise, the result cannot be what you want it to be.

Read The Floating-Point Guide for more information.

You can also login to the redis-cli and use the MONITOR command to see what queries are happening against Redis.

See ?boxplot for all the help you need.

 outline: if ‘outline’ is not true, the outliers are not drawn (as
          points whereas S+ uses lines).

boxplot(x,horizontal=TRUE,axes=FALSE,outline=FALSE)

And for extending the range of the whiskers and suppressing the outliers inside this range:

   range: this determines how far the plot whiskers extend out from the
          box.  If ‘range’ is positive, the whiskers extend to the most
          extreme data point which is no more than ‘range’ times the
          interquartile range from the box. A value of zero causes the
          whiskers to extend to the data extremes.

# change the value of range to change the whisker length
boxplot(x,horizontal=TRUE,axes=FALSE,range=2)

The following worked for me:

1. run VBoxManage internalcommands sethduuid "VDI/VMDK file" twice (the first time is just to conveniently generate an UUID, you could use any other UUID generation method instead)

2. open the .vbox file in a text editor

3. replace the UUID found in Machine uuid="{...}" with the UUID you got when you ran sethduuid the first time

4. replace the UUID found in HardDisk uuid="{...}" and in Image uuid="{}" (towards the end) with the UUID you got when you ran sethduuid the second time

I recently had this problem and it ended up being a port issue. My production SQL Server was set up at to be port 1427 instead 1433.

Just change the connection string to be

...data source=MySQLServerName,1427;initial catalog=MyDBName...

Hope this helps anyone who might be seeing this same issue.

Based on Blorgbeard's solution.

foreach (var sqlBatch in commandText.Split(new[] { "GO" }, StringSplitOptions.RemoveEmptyEntries))
{
   sqlCommand.CommandText = sqlBatch;
   sqlCommand.ExecuteNonQuery();
}

prods.Remove(prods.Single(p=>p.ID == 1));

you can't modify collection in foreach, as Vincent suggests

There is more than one way to do that but simple one is using String.split(" ") this is a method of String class that separate words by a spacial character(s) like " " (space)

All we need to do is save this word in an Array of Strings.

Warning : you have to use scan.nextLine(); other ways its not going to work(Do not use scan.next();

String user_input = scan.nextLine();
String[] stringsArray = user_input.split(" ");

now we need to convert these strings to Integers. create a for loop and convert every single index of stringArray :

for (int i = 0; i < stringsArray.length; i++) {
    int x = Integer.parseInt(stringsArray[i]);
    // Do what you want to do with these int value here
}

Best way is converting the whole stringArray to an intArray :

 int[] intArray = new int[stringsArray.length];
 for (int i = 0; i < stringsArray.length; i++) {
    intArray[i] = Integer.parseInt(stringsArray[i]);
 }

now do any proses you want like print or sum or... on intArray

The whole code will be like this :

import java.util.Scanner;
public class Main {
    public static void main(String[] args) {

        Scanner scan = new Scanner(System.in);
        String user_input = scan.nextLine();
        String[] stringsArray = user_input.split(" ");

        int[] intArray = new int[stringsArray.length];
        for (int i = 0; i < stringsArray.length; i++) {
            intArray[i] = Integer.parseInt(stringsArray[i]);
        }
    }
}

There's no need, just use fadeToggle() on the element:

$('#testElement').fadeToggle('fast');

Here's a demo.

SELECT  name, LENGTH(name) AS mlen
FROM    mytable
ORDER BY
        mlen DESC
LIMIT 1

You could do something like this:

public System.Collections.IEnumerable GetDogsWithBreedNames()
{
    var db = new DogDataContext(ConnectString);
    var result = from d in db.Dogs
                 join b in db.Breeds on d.BreedId equals b.BreedId
                 select new
                        {
                            Name = d.Name,
                            BreedName = b.BreedName
                        };
    return result.ToList();
}

There's more than one way to skin this problem so here's my solution:

1. Use Select() to convert the key-value pair to a string;
2. Convert to a list of strings;
3. Write out to the console using ForEach().

dict.Select(i => $"{i.Key}: {i.Value}").ToList().ForEach(Console.WriteLine);

You are comparing a jQuery object (jQuery('input:first')) to strings (the elements of the array).
Change the code in order to compare the input's value (wich is a string) to the array elements:

if (jQuery.inArray(jQuery("input:first").val(), ar) != -1)

The inArray method returns -1 if the element wasn't found in the array, so as your bonus answer to how to determine if an element is not in an array, use this :

if(jQuery.inArray(el,arr) == -1){
    // the element is not in the array
};

for (i,j) in [(i,j) for i in range(x) for j in range(y)]

should do it.

Improved answer to take into account circular references within objects. It also displays the path it took to get there.

In this example, I am searching for an iframe that I know is somewhere within a global object:

const objDone = []
var i = 2
function getObject(theObject, k) {
    if (i < 1 || objDone.indexOf(theObject) > -1) return
    objDone.push(theObject)
    var result = null;
    if(theObject instanceof Array) {
        for(var i = 0; i < theObject.length; i++) {
            result = getObject(theObject[i], i);
            if (result) {
                break;
            }   
        }
    }
    else
    {
        for(var prop in theObject) {
            if(prop == 'iframe' && theObject[prop]) {
                i--;
                console.log('iframe', theObject[prop])
                return theObject[prop]
            }
            if(theObject[prop] instanceof Object || theObject[prop] instanceof Array) {
                result = getObject(theObject[prop], prop);
                if (result) {
                    break;
                }
            } 
        }
    }
    if (result) console.info(k)
    return result;
}

Running the following: getObject(reader, 'reader') gave the following output and the iframe element in the end:

iframe // (The Dom Element)
_views
views
manager
rendition
book

NOTE: The path is in reverse order reader.book.rendition.manager.views._views.iframe

It is free and regularly updated. There are binaries available for both Linux and Windows.
It can handle flash on Windows. (It may do so on Linux as well, untested)

For integers you can use Integer.signum()

Returns the signum function of the specified int value. (The return value is -1 if the specified value is negative; 0 if the specified value is zero; and 1 if the specified value is positive.)

In servers, you may like to send RST instead of FIN when disconnecting misbehaving clients. That skips FIN-WAIT followed by TIME-WAIT socket states in the server, which prevents from depleting server resources, and, hence, protects from this kind of denial-of-service attack.

For a non-specific package and a more general solution you can check out pip-review, a tool that checks what packages could/should be updated.

$ pip-review --interactive

Why don't you use a combination of HTML/CSS instead? Image maps are obsolete.

This btw is Search Engine Optimised as well :)

Source code follows:

.image-map {
  background: url('https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png');
  width: 272px;
  height: 92px;
  display: block;
  position: relative;
  margin-top:10px;
  float: left;
}

.image-map > a.map {
  position: absolute;
  display: block;
  border: 1px solid green;
}

<div class="image-map">
    <a class="map" rel="G" style="top: 0px; left: 0px; width: 70px; height: 95px;" href="#"></a>
    <a class="map" rel="o" style="top: 0px; left: 70px; width: 50px; height: 95px" href="#"></a>
    <a class="map" rel="o" style="top: 0px; left: 120px; width: 50px; height: 95px" href="#"></a>
    <a class="map" rel="g" style="top: 0px; left: 170px; width: 40px; height: 95px" href="#"></a>
    <a class="map" rel="l" style="top: 0px; left: 210px; width: 20px; height: 95px" href="#"></a>
    <a class="map" rel="e" style="top: 0px; left: 230px; width: 40px; height: 95px" href="#"></a>
</div>

EDIT:

After the numerous negative points this answer has received I have to come back and say that I can clearly see that you don't agree with my answer, but I personally still believe that is a better option than image maps.

Sure it cannot do polygons, it might have issues on manual page zoom, but personally I feel image maps are obsolete although still on the html5 specification. (It makes make more sense nowadays to try and replicate them using html5 canvas instead)

However I guess the target audience for this question does not agree with me.

You could also check this Are HTML Image Maps still used? and see the most highly voted answer just for reference.

It can also be /var/log/apache2/error.log if you are in google compute engine.

And you can view tail like this:

tail -f /var/log/apache2/error.log

This might be what you are looking for:

yourStream
    .filter(/* your criteria */)
    .findFirst()
    .get();

And better, if there's a possibility of matching no element, in which case get() will throw a NPE. So use:

yourStream
    .filter(/* your criteria */)
    .findFirst()
    .orElse(null); /* You could also create a default object here */

public static void main(String[] args) {
    class Stop {
        private final String stationName;
        private final int    passengerCount;

        Stop(final String stationName, final int passengerCount) {
            this.stationName    = stationName;
            this.passengerCount = passengerCount;
        }
    }

    List<Stop> stops = new LinkedList<>();

    stops.add(new Stop("Station1", 250));
    stops.add(new Stop("Station2", 275));
    stops.add(new Stop("Station3", 390));
    stops.add(new Stop("Station2", 210));
    stops.add(new Stop("Station1", 190));

    Stop firstStopAtStation1 = stops.stream()
            .filter(e -> e.stationName.equals("Station1"))
            .findFirst()
            .orElse(null);

    System.out.printf("At the first stop at Station1 there were %d passengers in the train.", firstStopAtStation1.passengerCount);
}

Output is:

At the first stop at Station1 there were 250 passengers in the train.

Another alternative to do the same thing is to filter on type=checkbox attribute:

$('input[type="checkbox"]').removeAttr('checked');

or

$('input[type="checkbox"]').prop('checked' , false);

Remeber that The difference between attributes and properties can be important in specific situations. Before jQuery 1.6, the .attr() method sometimes took property values into account when retrieving some attributes, which could cause inconsistent behavior. As of jQuery 1.6, the .prop() method provides a way to explicitly retrieve property values, while .attr() retrieves attributes.

Nope. The reason ActiveX can do it is because ActiveX is a little application that runs on the client's machine.

I would imagine access to such information via JavaScript would be a security vulnerability.

You can use this code to check whether the input string contains any spaces?

public static void main(String[]args)
{
    Scanner sc=new Scanner(System.in);
    System.out.println("enter the string...");
    String s1=sc.nextLine();
    int l=s1.length();
    int count=0;
    for(int i=0;i<l;i++)
    {
        char c=s1.charAt(i);
        if(c==' ')
        {
        System.out.println("spaces are in the position of "+i);
        System.out.println(count++);
        }
        else
        {
        System.out.println("no spaces are there");
    }
}

Use the push() function to append to an array:

// initialize array
var arr = [
    "Hi",
    "Hello",
    "Bonjour"
];

// append new value to the array
arr.push("Hola");

Now array is

var arr = [
    "Hi",
    "Hello",
    "Bonjour"
    "Hola"
];

// append multiple values to the array
arr.push("Salut", "Hey");

Now array is

var arr = [
    "Hi",
    "Hello",
    "Bonjour"
    "Hola"
    "Salut"
    "Hey"
];

// display all values
for (var i = 0; i < arr.length; i++) {
    console.log(arr[i]);
}

Will print:

Hi
Hello
Bonjour
Hola 
Salut
Hey

Update

If you want to add the items of one array to another array, you can use Array.concat:

var arr = [
    "apple",
    "banana",
    "cherry"
];

arr = arr.concat([
    "dragonfruit",
    "elderberry",
    "fig"
]);

console.log(arr);

Will print

["apple", "banana", "cherry", "dragonfruit", "elderberry", "fig"]

There are two ways to add references using VBA. .AddFromGuid(Guid, Major, Minor) and .AddFromFile(Filename). Which one is best depends on what you are trying to add a reference to. I almost always use .AddFromFile because the things I am referencing are other Excel VBA Projects and they aren't in the Windows Registry.

The example code you are showing will add a reference to the workbook the code is in. I generally don't see any point in doing that because 90% of the time, before you can add the reference, the code has already failed to compile because the reference is missing. (And if it didn't fail-to-compile, you are probably using late binding and you don't need to add a reference.)

If you are having problems getting the code to run, there are two possible issues.

1. In order to easily use the VBE's object model, you need to add a reference to Microsoft Visual Basic for Application Extensibility. (VBIDE)
2. In order to run Excel VBA code that changes anything in a VBProject, you need to Trust access to the VBA Project Object Model. (In Excel 2010, it is located in the Trust Center - Macro Settings.)

Aside from that, if you can be a little more clear on what your question is or what you are trying to do that isn't working, I could give a more specific answer.

What about something like this?

>>> bin(int('ff', base=16))
'0b11111111'

This will convert the hexadecimal string you have to an integer and that integer to a string in which each byte is set to 0/1 depending on the bit-value of the integer.

As pointed out by a comment, if you need to get rid of the 0b prefix, you can do it this way:

>>> bin(int('ff', base=16)).lstrip('0b')
'11111111'

or this way:

>>> bin(int('ff', base=16))[2:]
'11111111'

-webkit-transform is no more needed

ms already support rotation ( -ms-transform: rotate(-10deg); )

try this:

li a {
   ...

    -webkit-transform: rotate(-10deg);
    -moz-transform: rotate(-10deg);
    -o-transform: rotate(-10deg);
    -ms-transform: rotate(-10deg);
    -sand-transform: rotate(10deg);
    display: block;
    position: fixed;
    }

In JQuery you can call

$("form:first").trigger("submit")

Don't know if that is much better. I think form.submit(); is pretty universal.

Another respondent (McDowell) said that polymorphism only works for object instances. That should be qualified; there are languages that do treat classes as instances of a "Class" or "Metaclass" type. These languages do support polymorphism for both instance and class (static) methods.

C#, like Java and C++ before it, is not such a language; the static keyword is used explicitly to denote that the method is statically-bound rather than dynamic/virtual.

I created an AdaptiveTabLayout class to achieve this. This was the only way I found to actually solve the problem, answer the question and avoid/workaround problems that other answers here don't.

Notes:

• Handles phone/tablet layouts.
• Handles cases where there's enough room for MODE_SCROLLABLE but not enough room for MODE_FIXED. If you don't handle this case it's gonna happen on some devices you'll see different text sizes or oven two lines of text in some tabs, which looks bad.
• It gets real measures and doesn't make any assumptions (like screen is 360dp wide or whatever...). This works with real screen sizes and real tab sizes. This means works well with translations because doesn't assume any tab size, the tabs get measure.
• Deals with the different passes on the onLayout phase in order to avoid extra work.
• Layout width needs to be wrap_content on the xml. Don't set any mode or gravity on the xml.

            }
        }

        return widestTab * tabCount;
    }

}

And this is the DeviceUtils class:

import android.content.res.Resources;

public class UtilsDevice extends Utils
{
    private static final int sWIDTH_FOR_BIG_TABLET_IN_DP = 720;

    private UtilsDevice() {}

    public static int pixelToDp(final int pixels)
    {
        return (int) (pixels / Resources.getSystem().getDisplayMetrics().density);
    }

    public static int getScreenWidth()
    {
        return Resources
                .getSystem()
                .getDisplayMetrics()
                .widthPixels;
    }

    public static boolean isBigTablet()
    {
        return pixelToDp(getScreenWidth()) >= sWIDTH_FOR_BIG_TABLET_IN_DP;
    }

}

I'm not sure how to solve it. Any suggestions?

• To make the TabLayout child measures, I'm making some castings and assumptions (Like the child is a LinearLayout containing other views....) This might cause problems with in further Design Support Library updates. A better approach/suggestions?

Check that ruby interpreter is already installed and try "ruby setup.rb" in command prompt.

var i = 0;_x000D_
var length = 10;_x000D_
_x000D_
function for1() {_x000D_
  console.log(i);_x000D_
  for2();_x000D_
}_x000D_
_x000D_
function for2() {_x000D_

    i++;_x000D_
    for1();_x000D_
  }, 500);_x000D_
}_x000D_
for1();

Here is a sample functional approach to what is expected here.

If the case is accessing the IFrame via console, e. g. Chrome Dev Tools then you can just select the context of DOM requests via dropdown (see the picture).

Because there are two print statements. First is inside function and second is outside function. When function not return any thing that time it return None value.

Use return statement at end of function to return value.

e.g.:

Return None value.

>>> def test1():
...    print "In function."
... 
>>> a = test1()
In function.
>>> print a
None
>>> 
>>> print test1()
In function.
None
>>>
>>> test1()
In function.
>>> 

Use return statement

>>> def test():
...   return "ACV"
... 
>>> print test()
ACV
>>> 
>>> a = test()
>>> print a
ACV
>>>

Answered code-snippet posted by Leandros seems bit old. I have fixed and made it compilable in Swift 5.

Swift 5

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
    self.window = UIWindow(frame: UIScreen.main.bounds)
    let controller = UIViewController()
    let view = UIView(frame: CGRect(x: 0, y: 0, width: 320, height: 568))
    view.backgroundColor = UIColor.red
    controller.view = view

    let label = UILabel(frame: CGRect(x: 0, y: 0, width: 200, height: 21))
    label.center = CGPoint(x: 160, y: 284)
    label.textAlignment = NSTextAlignment.center
    label.text = "I'am a test label"
    controller.view.addSubview(label)

    self.window!.rootViewController = controller
    self.window!.makeKeyAndVisible()
    return true
}

The printf function interprets the value that you pass it according to the format specifier in a matching position. If you tell printf that you pass an int, but pass unsigned instead, printf would re-interpret one as the other, and print the results that you see.

Language features:

Templates and Generic Code

• Template argument deduction for class templates

  • Like how functions deduce template arguments, now constructors can deduce the template arguments of the class
  • http://wg21.link/p0433r2 http://wg21.link/p0620r0 http://wg21.link/p0512r0

• template <auto>

  • Represents a value of any (non-type template argument) type.

• Non-type template arguments fixes

• template<template<class...>typename bob> struct foo {}

• ( Folding + ... + expressions ) and Revisions

• auto x{8}; is an int

• modernizing using with ... and lists

Lambda

• constexpr lambdas

  • Lambdas are implicitly constexpr if they qualify

• Capturing *this in lambdas

  • [*this]{ std::cout << could << " be " << useful << '\n'; }

Attributes

• [[fallthrough]], [[nodiscard]], [[maybe_unused]] attributes

• [[attributes]] on namespaces and enum { erator[[s]] }

• using in attributes to avoid having to repeat an attribute namespace.

• Compilers are now required to ignore non-standard attributes they don't recognize.

  • The C++14 wording allowed compilers to reject unknown scoped attributes.

Syntax cleanup

• Inline variables

  • Like inline functions
  • Compiler picks where the instance is instantiated
  • Deprecate static constexpr redeclaration, now implicitly inline.

• namespace A::B

• Simple static_assert(expression); with no string

• no throw unless throw(), and throw() is noexcept(true).

Cleaner multi-return and flow control

• Structured bindings

  • Basically, first-class std::tie with auto
  • Example:
    • const auto [it, inserted] = map.insert( {"foo", bar} );
    • Creates variables it and inserted with deduced type from the pair that map::insert returns.
  • Works with tuple/pair-likes & std::arrays and relatively flat structs
  • Actually named structured bindings in standard

• if (init; condition) and switch (init; condition)

  • if (const auto [it, inserted] = map.insert( {"foo", bar} ); inserted)
  • Extends the if(decl) to cases where decl isn't convertible-to-bool sensibly.

• Generalizing range-based for loops

  • Appears to be mostly support for sentinels, or end iterators that are not the same type as begin iterators, which helps with null-terminated loops and the like.

• if constexpr

  • Much requested feature to simplify almost-generic code.

Misc

• Hexadecimal float point literals

• Dynamic memory allocation for over-aligned data

• Guaranteed copy elision

  • Finally!
  • Not in all cases, but distinguishes syntax where you are "just creating something" that was called elision, from "genuine elision".

• Fixed order-of-evaluation for (some) expressions with some modifications

  • Not including function arguments, but function argument evaluation interleaving now banned
  • Makes a bunch of broken code work mostly, and makes .then on future work.

• Direct list-initialization of enums

• Forward progress guarantees (FPG) (also, FPGs for parallel algorithms)

  • I think this is saying "the implementation may not stall threads forever"?

• u8'U', u8'T', u8'F', u8'8' character literals (string already existed)

• "noexcept" in the type system

• __has_include

  • Test if a header file include would be an error
  • makes migrating from experimental to std almost seamless

• Arrays of pointer conversion fixes

• inherited constructors fixes to some corner cases (see P0136R0 for examples of behavior changes)

• aggregate initialization with inheritance.

• std::launder, type punning, etc

Library additions:

Data types

• std::variant<Ts...>

  • Almost-always non-empty last I checked?
  • Tagged union type
  • {awesome|useful}

• std::optional

  • Maybe holds one of something
  • Ridiculously useful

• std::any

  • Holds one of anything (that is copyable)

• std::string_view

  • std::string like reference-to-character-array or substring
  • Never take a string const& again. Also can make parsing a bajillion times faster.
  • "hello world"sv
  • constexpr char_traits

• std::byte off more than they could chew.

  • Neither an integer nor a character, just data

Invoke stuff

• std::invoke
  • Call any callable (function pointer, function, member pointer) with one syntax. From the standard INVOKE concept.
• std::apply
  • Takes a function-like and a tuple, and unpacks the tuple into the call.

• std::make_from_tuple, std::apply applied to object construction

• is_invocable, is_invocable_r, invoke_result

  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0077r2.html
  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2017/p0604r0.html
  • Deprecates result_of
  • is_invocable<Foo(Args...), R> is "can you call Foo with Args... and get something compatible with R", where R=void is default.
  • invoke_result<Foo, Args...> is std::result_of_t<Foo(Args...)> but apparently less confusing?

File System TS v1

• [class.path]

• [class.filesystem.error]

• [class.file_status]

• [class.directory_entry]

• [class.directory_iterator] and [class.recursive_directory_iterator]

• [fs.ops.funcs]

• fstreams can be opened with paths, as well as with const path::value_type* strings.

New algorithms

• for_each_n

• reduce

• transform_reduce

• exclusive_scan

• inclusive_scan

• transform_exclusive_scan

• transform_inclusive_scan

• Added for threading purposes, exposed even if you aren't using them threaded

Threading

• std::shared_mutex

  • Untimed, which can be more efficient if you don't need it.

• atomic<T>::is_always_lockfree

• scoped_lock<Mutexes...>

  • Saves some std::lock pain when locking more than one mutex at a time.

• Parallelism TS v1

  • The linked paper from 2014, may be out of date
  • Parallel versions of std algorithms, and related machinery

• hardware_*_interference_size

(parts of) Library Fundamentals TS v1 not covered above or below

• [func.searchers] and [alg.search]
  • A searching algorithm and techniques

• [pmr]

  • Polymorphic allocator, like std::function for allocators
  • And some standard memory resources to go with it.
  • http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2016/p0358r1.html

• std::sample, sampling from a range?

Container Improvements

• try_emplace and insert_or_assign

  • gives better guarantees in some cases where spurious move/copy would be bad

• Splicing for map<>, unordered_map<>, set<>, and unordered_set<>

  • Move nodes between containers cheaply.
  • Merge whole containers cheaply.

• non-const .data() for string.

• non-member std::size, std::empty, std::data

  • like std::begin/end

• Minimal incomplete type support in containers

• Contiguous iterator "concept"

• constexpr iterators

• The emplace family of functions now returns a reference to the created object.

Smart pointer changes

• unique_ptr<T[]> fixes and other unique_ptr tweaks.
• weak_from_this and some fixed to shared from this

Other std datatype improvements:

• {} construction of std::tuple and other improvements

Isocpp.org has has an independent list of changes since C++14; it has been partly pillaged.

Naturally TS work continues in parallel, so there are some TS that are not-quite-ripe that will have to wait for the next iteration. The target for the next iteration is C++20 as previously planned, not C++19 as some rumors implied. C++1O has been avoided.

Initial list taken from this reddit post and this reddit post, with links added via googling or from the above isocpp.org page.

Additional entries pillaged from SD-6 feature-test list.

clang's feature list and library feature list are next to be pillaged. This doesn't seem to be reliable, as it is C++1z, not C++17.

these slides had some features missing elsewhere.

While "what was removed" was not asked, here is a short list of a few things ((mostly?) previous deprecated) that are removed in C++17 from C++:

Removed:

• register, keyword reserved for future use
• bool b; ++b;
• trigraphs
  • if you still need them, they are now part of your source file encoding, not part of language
• ios aliases
• auto_ptr, old <functional> stuff, random_shuffle
• allocators in std::function

There were rewordings. I am unsure if these have any impact on code, or if they are just cleanups in the standard:

Papers not yet integrated into above:

• P0505R0 (constexpr chrono)

• P0418R2 (atomic tweaks)

• P0512R0 (template argument deduction tweaks)

• P0490R0 (structured binding tweaks)

• P0513R0 (changes to std::hash)

• P0502R0 (parallel exceptions)

• P0509R1 (updating restrictions on exception handling)

• P0012R1 (make exception specifications be part of the type system)

• P0510R0 (restrictions on variants)

• P0504R0 (tags for optional/variant/any)

• P0497R0 (shared ptr tweaks)

• P0508R0 (structured bindings node handles)

• P0521R0 (shared pointer use count and unique changes?)

Spec changes:

• exception specs and throw expressions

Error 127 means one of two things:

1. file not found: the path you're using is incorrect. double check that the program is actually in your $PATH, or in this case, the relative path is correct -- remember that the current working directory for a random terminal might not be the same for the IDE you're using. it might be better to just use an absolute path instead.
2. ldso is not found: you're using a pre-compiled binary and it wants an interpreter that isn't on your system. maybe you're using an x86_64 (64-bit) distro, but the prebuilt is for x86 (32-bit). you can determine whether this is the answer by opening a terminal and attempting to execute it directly. or by running file -L on /bin/sh (to get your default/native format) and on the compiler itself (to see what format it is).

if the problem is (2), then you can solve it in a few diff ways:

1. get a better binary. talk to the vendor that gave you the toolchain and ask them for one that doesn't suck.
2. see if your distro can install the multilib set of files. most x86_64 64-bit distros allow you to install x86 32-bit libraries in parallel.
3. build your own cross-compiler using something like crosstool-ng.
4. you could switch between an x86_64 & x86 install, but that seems a bit drastic ;).

Actually, all of those examples on the web wherein the common content/file type like "js", "css", "img", etc is been used as library name are misleading.

Real world examples

To start, let's look at how existing JSF implementations like Mojarra and MyFaces and JSF component libraries like PrimeFaces and OmniFaces use it. No one of them use resource libraries this way. They use it (under the covers, by @ResourceDependency or UIViewRoot#addComponentResource()) the following way:

<h:outputScript library="javax.faces" name="jsf.js" />
<h:outputScript library="primefaces" name="jquery/jquery.js" />
<h:outputScript library="omnifaces" name="omnifaces.js" />
<h:outputScript library="omnifaces" name="fixviewstate.js" />
<h:outputScript library="omnifaces.combined" name="[dynamicname].js" />
<h:outputStylesheet library="primefaces" name="primefaces.css" />
<h:outputStylesheet library="primefaces-aristo" name="theme.css" />
<h:outputStylesheet library="primefaces-vader" name="theme.css" />

It should become clear that it basically represents the common library/module/theme name where all of those resources commonly belong to.

Easier identifying

This way it's so much easier to specify and distinguish where those resources belong to and/or are coming from. Imagine that you happen to have a primefaces.css resource in your own webapp wherein you're overriding/finetuning some default CSS of PrimeFaces; if PrimeFaces didn't use a library name for its own primefaces.css, then the PrimeFaces own one wouldn't be loaded, but instead the webapp-supplied one, which would break the look'n'feel.

Also, when you're using a custom ResourceHandler, you can also apply more finer grained control over resources coming from a specific library when library is used the right way. If all component libraries would have used "js" for all their JS files, how would the ResourceHandler ever distinguish if it's coming from a specific component library? Examples are OmniFaces CombinedResourceHandler and GraphicResourceHandler; check the createResource() method wherein the library is checked before delegating to next resource handler in chain. This way they know when to create CombinedResource or GraphicResource for the purpose.

Noted should be that RichFaces did it wrong. It didn't use any library at all and homebrewed another resource handling layer over it and it's therefore impossible to programmatically identify RichFaces resources. That's exactly the reason why OmniFaces CombinedResourceHander had to introduce a reflection-based hack in order to get it to work anyway with RichFaces resources.

Your own webapp

Your own webapp does not necessarily need a resource library. You'd best just omit it.

<h:outputStylesheet name="css/style.css" />
<h:outputScript name="js/script.js" />
<h:graphicImage name="img/logo.png" />

Or, if you really need to have one, you can just give it a more sensible common name, like "default" or some company name.

<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />

Or, when the resources are specific to some master Facelets template, you could also give it the name of the template, so that it's easier to relate each other. In other words, it's more for self-documentary purposes. E.g. in a /WEB-INF/templates/layout.xhtml template file:

<h:outputStylesheet library="layout" name="css/style.css" />
<h:outputScript library="layout" name="js/script.js" />

And a /WEB-INF/templates/admin.xhtml template file:

<h:outputStylesheet library="admin" name="css/style.css" />
<h:outputScript library="admin" name="js/script.js" />

For a real world example, check the OmniFaces showcase source code.

Or, when you'd like to share the same resources over multiple webapps and have created a "common" project for that based on the same example as in this answer which is in turn embedded as JAR in webapp's /WEB-INF/lib, then also reference it as library (name is free to your choice; component libraries like OmniFaces and PrimeFaces also work that way):

<h:outputStylesheet library="common" name="css/style.css" />
<h:outputScript library="common" name="js/script.js" />
<h:graphicImage library="common" name="img/logo.png" />

Library versioning

Another main advantage is that you can apply resource library versioning the right way on resources provided by your own webapp (this doesn't work for resources embedded in a JAR). You can create a direct child subfolder in the library folder with a name in the \d+(_\d+)* pattern to denote the resource library version.

WebContent
 |-- resources
 |    `-- default
 |         `-- 1_0
 |              |-- css
 |              |    `-- style.css
 |              |-- img
 |              |    `-- logo.png
 |              `-- js
 |                   `-- script.js
 :

When using this markup:

<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />

This will generate the following HTML with the library version as v parameter:

<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&amp;v=1_0" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&amp;v=1_0"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&amp;v=1_0" alt="" />

So, if you have edited/updated some resource, then all you need to do is to copy or rename the version folder into a new value. If you have multiple version folders, then the JSF ResourceHandler will automatically serve the resource from the highest version number, according to numerical ordering rules.

So, when copying/renaming resources/default/1_0/* folder into resources/default/1_1/* like follows:

WebContent
 |-- resources
 |    `-- default
 |         |-- 1_0
 |         |    :
 |         |
 |         `-- 1_1
 |              |-- css
 |              |    `-- style.css
 |              |-- img
 |              |    `-- logo.png
 |              `-- js
 |                   `-- script.js
 :

Then the last markup example would generate the following HTML:

<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&amp;v=1_1" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&amp;v=1_1"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&amp;v=1_1" alt="" />

This will force the webbrowser to request the resource straight from the server instead of showing the one with the same name from the cache, when the URL with the changed parameter is been requested for the first time. This way the endusers aren't required to do a hard refresh (Ctrl+F5 and so on) when they need to retrieve the updated CSS/JS resource.

Please note that library versioning is not possible for resources enclosed in a JAR file. You'd need a custom ResourceHandler. See also How to use JSF versioning for resources in jar.

First off, interpreted/compiled is not a property of the language but a property of the implementation. For most languages, most if not all implementations fall in one category, so one might save a few words saying the language is interpreted/compiled too, but it's still an important distinction, both because it aids understanding and because there are quite a few languages with usable implementations of both kinds (mostly in the realm of functional languages, see Haskell and ML). In addition, there are C interpreters and projects that attempt to compile a subset of Python to C or C++ code (and subsequently to machine code).

Second, compilation is not restricted to ahead-of-time compilation to native machine code. A compiler is, more generally, a program that converts a program in one programming language into a program in another programming language (arguably, you can even have a compiler with the same input and output language if significant transformations are applied). And JIT compilers compile to native machine code at runtime, which can give speed very close to or even better than ahead of time compilation (depending on the benchmark and the quality of the implementations compared).

But to stop nitpicking and answer the question you meant to ask: Practically (read: using a somewhat popular and mature implementation), Python is compiled. Not compiled to machine code ahead of time (i.e. "compiled" by the restricted and wrong, but alas common definition), "only" compiled to bytecode, but it's still compilation with at least some of the benefits. For example, the statement a = b.c() is compiled to a byte stream which, when "disassembled", looks somewhat like load 0 (b); load_str 'c'; get_attr; call_function 0; store 1 (a). This is a simplification, it's actually less readable and a bit more low-level - you can experiment with the standard library dis module and see what the real deal looks like. Interpreting this is faster than interpreting from a higher-level representation.

That bytecode is either interpreted (note that there's a difference, both in theory and in practical performance, between interpreting directly and first compiling to some intermediate representation and interpret that), as with the reference implementation (CPython), or both interpreted and compiled to optimized machine code at runtime, as with PyPy.

Popular solution is to append username and password in URL, like, http://username:[email protected]. However, if your username or password contains special character, then it may fail. So when you create the URL, make sure you encode those special characters.

String username = URLEncoder.encode(user, StandardCharsets.UTF_8.toString());
String password = URLEncoder.encode(pass, StandardCharsets.UTF_8.toString());
String url = “http://“ + username + “:” + password + “@website.com”;
driver.get(url);

Perhaps get the size of the string and loop through each character and call isDigit() on each character. If it is a digit, then add it to a string that only collects the numbers before calling Integer.parseInt().

Something like:

    String something = "423e";
    int length = something.length();
    String result = "";
    for (int i = 0; i < length; i++) {
        Character character = something.charAt(i);
        if (Character.isDigit(character)) {
            result += character;
        }
    }
    System.out.println("result is: " + result);

As you noticed, these are Makefile {macros or variables}, not compiler options. They implement a set of conventions. (Macros is an old name for them, still used by some. GNU make doc calls them variables.)

The only reason that the names matter is the default make rules, visible via make -p, which use some of them.

If you write all your own rules, you get to pick all your own macro names.

In a vanilla gnu make, there's no such thing as CCFLAGS. There are CFLAGS, CPPFLAGS, and CXXFLAGS. CFLAGS for the C compiler, CXXFLAGS for C++, and CPPFLAGS for both.

Why is CPPFLAGS in both? Conventionally, it's the home of preprocessor flags (-D, -U) and both c and c++ use them. Now, the assumption that everyone wants the same define environment for c and c++ is perhaps questionable, but traditional.

P.S. As noted by James Moore, some projects use CPPFLAGS for flags to the C++ compiler, not flags to the C preprocessor. The Android NDK, for one huge example.

//Response being your httpwebresponse
Dim str_StatusCode as String = CInt(Response.StatusCode)
Console.Writeline(str_StatusCode)

Other answers here address the general question of what the proper Content-Type for an XML response is, and conclude (as with What's the difference between text/xml vs application/xml for webservice response) that both text/xml and application/xml are permissible. However, none address whether there are any rules specific to sitemaps.

Answer: there aren't. The sitemap spec is https://www.sitemaps.org, and using Google site: searches you can confirm that it does not contain the words or phrases mime, mimetype, content-type, application/xml, or text/xml anywhere. In other words, it is entirely silent on the topic of what Content-Type should be used for serving sitemaps.

In the absence of any commentary in the sitemap spec directly addressing this question, we can safely assume that the same rules apply as when choosing the Content-Type of any other XML document - i.e. that it may be either text/xml or application/xml.

You want the String.strip(s[, chars]) function, which will strip out whitespace characters or whatever characters (such as '\n') you specify in the chars argument.

See http://docs.python.org/release/2.3/lib/module-string.html

ArrayList<String> list = new ArrayList<String>();     
JSONArray jsonArray = (JSONArray)jsonObject; 
if (jsonArray != null) { 
   int len = jsonArray.length();
   for (int i=0;i<len;i++){ 
    list.add(jsonArray.get(i).toString());
   } 
} 

In Word, it is possible to paste code that uses color to differentiate comments from code using "Paste Keep Source Formatting." However, if you use the pasted code to create a new style, Word automatically strips the color coded text and changes them to be black (or whatever the auto default color is). Since applying a style is the best way to ensure compliance with document format requirements, Word is not very useful for documenting software programs. Unfortunately, I don't recall Open Office being any better. The best work-around is to use the default simple text box.

DECLARE @EndTime AS DATETIME, @StartTime AS DATETIME

SELECT @StartTime = '2013-03-08 08:00:00', @EndTime = '2013-03-08 08:30:00'

SELECT CAST(@EndTime - @StartTime AS TIME)

Result: 00:30:00.0000000

Format result as you see fit.

localStorage is something that is kept on the client side. There is no data transmitted to the server side.

You can only get the data with JavaScript and you can send it to the server side with Ajax.

Put both and make each update the other. If the user chooses the date from the datepicker, it is easy to fix a minor misclick in the text field or visualize the choise you typed into text field in the datepicker.

You can change it inside bs-config.json file as mentioned in the docs https://github.com/johnpapa/lite-server#custom-configuration

For example,

{
  "port": 8000,
  "files": ["./src/**/*.{html,htm,css,js}"],
  "server": { "baseDir": "./src" }
}

-1 isn't special in the sense that the sequence is read backwards, it rather wraps around the ends. Such that minus one means zero minus one, exclusive (and, for a positive step value, the sequence is read "from left to right".

so for i = [1, 2, 3, 4], i[2:-1] means from item two to the beginning minus one (or, 'around to the end'), which results in [3]. The -1th element, or element 0 backwards 1 is the last 4, but since it's exclusive, we get 3.

I hope this is somewhat understandable.

Some limitations though to Steven Bethard's solution :

When you register your class method as a function, the destructor of your class is surprisingly called every time your method processing is finished. So if you have 1 instance of your class that calls n times its method, members may disappear between 2 runs and you may get a message malloc: *** error for object 0x...: pointer being freed was not allocated (e.g. open member file) or pure virtual method called, terminate called without an active exception (which means than the lifetime of a member object I used was shorter than what I thought). I got this when dealing with n greater than the pool size. Here is a short example :

from multiprocessing import Pool, cpu_count
from multiprocessing.pool import ApplyResult

# --------- see Stenven's solution above -------------
from copy_reg import pickle
from types import MethodType

def _pickle_method(method):
    func_name = method.im_func.__name__
    obj = method.im_self
    cls = method.im_class
    return _unpickle_method, (func_name, obj, cls)

def _unpickle_method(func_name, obj, cls):
    for cls in cls.mro():
        try:
            func = cls.__dict__[func_name]
        except KeyError:
            pass
        else:
            break
    return func.__get__(obj, cls)


class Myclass(object):

    def __init__(self, nobj, workers=cpu_count()):

        print "Constructor ..."
        # multi-processing
        pool = Pool(processes=workers)
        async_results = [ pool.apply_async(self.process_obj, (i,)) for i in range(nobj) ]
        pool.close()
        # waiting for all results
        map(ApplyResult.wait, async_results)
        lst_results=[r.get() for r in async_results]
        print lst_results

    def __del__(self):
        print "... Destructor"

    def process_obj(self, index):
        print "object %d" % index
        return "results"

pickle(MethodType, _pickle_method, _unpickle_method)
Myclass(nobj=8, workers=3)
# problem !!! the destructor is called nobj times (instead of once)

Output:

Constructor ...
object 0
object 1
object 2
... Destructor
object 3
... Destructor
object 4
... Destructor
object 5
... Destructor
object 6
... Destructor
object 7
... Destructor
... Destructor
... Destructor
['results', 'results', 'results', 'results', 'results', 'results', 'results', 'results']
... Destructor

The __call__ method is not so equivalent, because [None,...] are read from the results :

from multiprocessing import Pool, cpu_count
from multiprocessing.pool import ApplyResult

class Myclass(object):

    def __init__(self, nobj, workers=cpu_count()):

        print "Constructor ..."
        # multiprocessing
        pool = Pool(processes=workers)
        async_results = [ pool.apply_async(self, (i,)) for i in range(nobj) ]
        pool.close()
        # waiting for all results
        map(ApplyResult.wait, async_results)
        lst_results=[r.get() for r in async_results]
        print lst_results

    def __call__(self, i):
        self.process_obj(i)

    def __del__(self):
        print "... Destructor"

    def process_obj(self, i):
        print "obj %d" % i
        return "result"

Myclass(nobj=8, workers=3)
# problem !!! the destructor is called nobj times (instead of once), 
# **and** results are empty !

So none of both methods is satisfying...

There are hardware and software watchpoints. They are for reading and for writing a variable. You need to consult a tutorial:

http://www.unknownroad.com/rtfm/gdbtut/gdbwatch.html

To set a watchpoint, first you need to break the code into a place where the varianle i is present in the environment, and set the watchpoint.

watch command is used to set a watchpoit for writing, while rwatch for reading, and awatch for reading/writing.

I liked FakeRainBrigand's answer, however it contains a few problems: It can not handle whitespace between a quote and a comma, and does not support 2 consecutive commas. I tried editing his answer but my edit got rejected by reviewers that apparently did not understand my code. Here is my version of FakeRainBrigand's code. There is also a fiddle: http://jsfiddle.net/xTezm/46/

            matches[n] = matches[n].trim();
            if (matches[n] == ',') matches[n] = '';
        }
        if (this[0] == ',') matches.unshift("");

As explained in "Deleting your master branch" by Matthew Brett, you need to change your GitHub repo default branch.

You need to go to the GitHub page for your forked repository, and click on the “Settings” button.

Click on the "Branches" tab on the left hand side. There’s a “Default branch” dropdown list near the top of the screen.

From there, select placeholder (where placeholder is the dummy name for your new default branch).

Confirm that you want to change your default branch.

Now you can do (from the command line):

git push origin :master

Or, since 2012, you can delete that same branch directly on GitHub:

That was announced in Sept. 2013, a year after I initially wrote that answer.

For small changes like documentation fixes, typos, or if you’re just a walking software compiler, you can get a lot done in your browser without needing to clone the entire repository to your computer.

Note: for BitBucket, Tum reports in the comments:

About the same for Bitbucket

Repo -> Settings -> Repository details -> Main branch

First of all, there can be two reasons for this:

1. You have created your own VPC and forgot to enable Public DNS.

To solve this :

i) Go to AWS VPC console and select the VPC you have created.

ii) Then click on Actions and then enable DNS Resolution.

            OR

2. You have not enabled public ip-assign option in EC2 configuration.

Here you cannot change the setting; so create an ami image and then recreate the instance from that.

Late to the game, but I found this method is extremely intuitive. https://codepen.io/adamchenwei/pen/BRNxJr

The default logging level is warning. Since you haven't changed the level, the root logger's level is still warning. That means that it will ignore any logging with a level that is lower than warning, including debug loggings.

This is explained in the tutorial:

import logging
logging.warning('Watch out!') # will print a message to the console
logging.info('I told you so') # will not print anything

The 'info' line doesn't print anything, because the level is higher than info.

To change the level, just set it in the root logger:

'root':{'handlers':('console', 'file'), 'level':'DEBUG'}

In other words, it's not enough to define a handler with level=DEBUG, the actual logging level must also be DEBUG in order to get it to output anything.

you could use "AUTHID CURRENT_USER" in body of your procedure definition for your requirements.

mysqli_fetch_array() returns NULL if there is no row.

In procedural style:

if ( ! $row = mysqli_fetch_array( $result ) ) {
    ... no result ...
}
else {
    ... get the first result in $row ...
}

In Object oriented style:

if ( ! $row = $result->fetch_array() ) {
    ...
}
else {
    ... get the first result in $row ...
}

You need to specify the schema/owner (dbo by default) as part of the reference. Also, it would be preferable to use the newer (ANSI-92) join style.

select foo.id 
    from databaseserver1.db1.dbo.table1 foo
        inner join databaseserver2.db1.dbo.table1 bar 
            on foo.name = bar.name

jQuery collections have a built in iterator with .each:

$("input[name^='card']").each(function () {
   console.log($(this).val());
}

Open Your .htaccess file and enter the following code in

Options -Indexes

Make sure you hit the ENTER key (or RETURN key if you use a Mac) after entering the "Options -Indexes" words so that the file ends with a blank line.

If you are in a directory or folder where the script file is available then simply change the file permission in executable mode by doing

chmod +x your_filename.sh

After that you will run the script by using the following command.

$ sudo ./your_filename.sh

Above the "." represent the current directory. Note! If you are not in the directory where the bash script file is present then you change the directory where the file is located by using

cd Directory_name/write the complete path

command. Otherwise your script can not run.

You are looking for a simple code, like this:

    List<string> tagList = new List<string>(new[]
    {
         "A"
        ,"B"
        ,"C"
        ,"D"
        ,"E"
    });

Quick note: if you're also using coord_flip() to flip the x and the y axis, you won't be able to set range limits using coord_cartesian() because those two functions are exclusive (see here).

Fortunately, this is an easy fix; set your limits within coord_flip() like so:

p + coord_flip(ylim = c(3,5), xlim = c(100, 400))

This just alters the visible range (i.e. doesn't remove data points).

SQL Server Script

declare @iDate datetime
set @iDate=GETDATE()

print year(@iDate) -- for Year

print month(@iDate) -- for Month

print day(@iDate) -- for Day

I use a few methods depending. In the same stylesheet i use: @media (max-width: 450px), or for separate make sure you have the link in the header correctly. I had a look at your fixmeup and you have a confusing array of links to css. It acts as you say also on HTC desire S.

The problem is clear: circular dependency between names in entity and physics modules.

Regardless of importing the whole module or just a class, the names must be loaded .

Watch this example:

# a.py
import b
def foo():
  pass
b.bar()

# b.py
import a
def bar():
  pass
a.foo()

This will be compiled into:

# a.py
# import b
# b.py
# import a # ignored, already importing
def bar():
  pass
a.foo()
# name a.foo is not defined!!!
# import b done!
def foo():
  pass
b.bar()
# done!

With one slight change we can solve this:

# a.py
def foo():
  pass
import b
b.bar()

# b.py
def bar():
  pass
import a
a.foo()

This will be compiled into:

# a.py
def foo():
  pass
# import b
# b.py
def bar():
  pass
# import a # ignored, already importing
a.foo()
# import b done!
b.bar()
# done!

I had to reinstall eclipse, delete .m2 folder and rebuild the jars.

You don't need the SELECT

DECLARE @LastChangeDate as date
SET @LastChangeDate = GetDate()

Just install pillow with pip install pillow and it will work.

An update. Dates of the form '2019-08-00' will trigger the same error. Adding the lines:

[mysqld]

sql_mode="NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION" 

to mysql.cnf fixes this too. Inserting malformed dates now generates warnings for values out of range but does insert the data.

When you call this:

data = Top15[['Citable docs per Capita','Energy Supply per Capita']]
correlation = data.corr(method='pearson')

Since, DataFrame.corr() function performs pair-wise correlations, you have four pair from two variables. So, basically you are getting diagonal values as auto correlation (correlation with itself, two values since you have two variables), and other two values as cross correlations of one vs another and vice versa.

Either perform correlation between two series to get a single value:

from scipy.stats.stats import pearsonr
docs_col = Top15['Citable docs per Capita'].values
energy_col = Top15['Energy Supply per Capita'].values
corr , _ = pearsonr(docs_col, energy_col)

or, if you want a single value from the same function (DataFrame's corr):

single_value = correlation[0][1] 

Hope this helps.

Does this not work (assuming "ROUTERNAME" is the user name the router expects)?

net use Z: "\\10.0.1.1\DRIVENAME" /user:"ROUTERNAME" "PW"

Alternatively, you can use use a small VBScript:

Option Explicit
Dim u, p, s, l
Dim Network: Set Network= CreateObject("WScript.Network")

l = "Z:"
s = "\\10.0.1.1\DRIVENAME"

u = "ROUTERNAME"
p = "PW"

Network.MapNetworkDrive l, s, False, u, p

Now in Swift 4.2 you can use pngData() new instance method of UIImage to get the data from the image

let profileImage = UIImage(named:"profile")!
let imageData = profileImage.pngData()

You can try progress bar instead of seek bar

<ProgressBar
    android:id="@+id/progressBar"
    style="?android:attr/progressBarStyleHorizontal"
    android:layout_width="fill_parent"
    android:layout_height="50dp"
    android:layout_marginBottom="35dp"
    />

If android:largeHeap="true" didn't work for you then

Image Compression. I am using this website

2:

Convert images to mdpi,hdpi, xhdpi, xxhdpi, xxxhdpi. I am using this webiste

Don't remove android:largeHeap="true"!

As mentioned before D3.js is definitely the best visualization library for charts. To use it in AngularJS I developed angular-chart. It is an easy to use directive which connects D3.js with the AngularJS 2-Way-DataBinding. This way the chart gets automatically updated whenever you change the configuration options and at the same time the charts saves its state (zoom level, ...) to make it available in the AngularJS world.

Check out the examples to get convinced.

Have you tried Spring Scheduler using annotations ?

@Scheduled(cron = "0 0 0/8 ? * * *")
public void scheduledMethodNoReturnValue(){
    //body can be another method call which returns some value.
}

you can do this with xml as well.

 <task:scheduled-tasks>
   <task:scheduled ref = "reference" method = "methodName" cron = "<cron expression here> -or- ${<cron expression from property files>}"
 <task:scheduled-tasks>

You might be just missing the column list, as the message says

SET IDENTITY_INSERT [MyDB].[dbo].[Equipment] ON

INSERT INTO [MyDB].[dbo].[Equipment]
            (COL1,
             COL2)
SELECT COL1,
       COL2
FROM   [MyDBQA].[dbo].[Equipment]

SET IDENTITY_INSERT [MyDB].[dbo].[Equipment] OFF 

In Python 2.7 and 3 you can use this:

import string
string.ascii_lowercase
'abcdefghijklmnopqrstuvwxyz'

string.ascii_uppercase
'ABCDEFGHIJKLMNOPQRSTUVWXYZ'

As @Zaz says: string.lowercase is deprecated and no longer works in Python 3 but string.ascii_lowercase works in both

@phoenix24 answer actually helped me (whose own asnwer did not solve my problem btw). The correct arguments for setCenter is

map.setCenter({lat:LAT_VALUE, lng:LONG_VALUE});

Google Documentation

By the way if your variable are lat and lng the following code will work

map.setCenter({lat:lat, lng:lng});

This actually solved my very intricate problem so I thought I will post it here.

This was not as straightforward as I would have hoped. You need to use enumerate to keep track of how many columns you have. Then use that counter to look up the name of the column. The accepted answer does not show you how to access the column names dynamically.

for row in df.itertuples(index=False, name=None):
    for k,v in enumerate(row):
        print("column: {0}".format(df.columns.values[k]))
        print("value: {0}".format(v)

It is very important to understand both sessionStorage and localStorage as they both have different uses:

From MDN:

All of your web storage data is contained within two object-like structures inside the browser: sessionStorage and localStorage. The first one persists data for as long as the browser is open (the data is lost when the browser is closed) and the second one persists data even after the browser is closed and then opened again.

sessionStorage - Saves data until the browser is closed, the data is deleted when the tab/browser is closed.

localStorage - Saves data "forever" even after the browser is closed BUT you shouldn't count on the data you store to be there later, the data might get deleted by the browser at any time because of pretty much anything, or deleted by the user, best practice would be to validate that the data is there first, and continue the rest if it is there. (or set it up again if its not there)

To understand more, read here: localStorage | sessionStorage

There is DiffMerge from SourceGear. It's pretty good. Araxis Merge is one of the programs I miss from Windows. I wonder if it works under Wine ;) Might have to give it a try

The style property lets you specify values for CSS properties.

The CSS width property takes a length as its value.

Lengths require units. In quirks mode, browsers tend to assume pixels if provided with an integer instead of a length. Specify units.

e1.style.width = "400px";
