[Twitter Bootstrap v3]

To create a n-level dropdown menu (touch device friendly) in Twitter Bootstrap v3,

• jsfiddle-demo of n-level dropdown menu v3.0.0 | v3.1.1 | v3.3.0

CSS:

.dropdown-menu>li /* To prevent selection of text */
{   position:relative;
    -webkit-user-select: none; /* Chrome/Safari */        
    -moz-user-select: none; /* Firefox */
    -ms-user-select: none; /* IE10+ */
    /* Rules below not implemented in browsers yet */
    -o-user-select: none;
    user-select: none;
    cursor:pointer;
}
.dropdown-menu .sub-menu 
{
    left: 100%;
    position: absolute;
    top: 0;
    display:none;
    margin-top: -1px;

}
.right-caret:after
{   border-left: 5px solid #ffaf46;
}
.left-caret:after
{   border-right: 5px solid #ffaf46;
}

JQuery:

$(function(){
    $(".dropdown-menu > li > a.trigger").on("click",function(e){
        var current=$(this).next();
        var grandparent=$(this).parent().parent();
        if($(this).hasClass('left-caret')||$(this).hasClass('right-caret'))

$('#textarea').blur()

Documentation at: http://api.jquery.com/blur/

You can always refer to resources in your application directly by their JNDI name as configured in the container, but if you do so, essentially you are wiring the container-specific name into your code. This has some disadvantages, for example, if you'll ever want to change the name later for some reason, you'll need to update all the references in all your applications, and then rebuild and redeploy them.

<resource-ref> introduces another layer of indirection: you specify the name you want to use in the web.xml, and, depending on the container, provide a binding in a container-specific configuration file.

So here's what happens: let's say you want to lookup the java:comp/env/jdbc/primaryDB name. The container finds that web.xml has a <resource-ref> element for jdbc/primaryDB, so it will look into the container-specific configuration, that contains something similar to the following:

<resource-ref>
  <res-ref-name>jdbc/primaryDB</res-ref-name>
  <jndi-name>jdbc/PrimaryDBInTheContainer</jndi-name>
</resource-ref>

Finally, it returns the object registered under the name of jdbc/PrimaryDBInTheContainer.

The idea is that specifying resources in the web.xml has the advantage of separating the developer role from the deployer role. In other words, as a developer, you don't have to know what your required resources are actually called in production, and as the guy deploying the application, you will have a nice list of names to map to real resources.

Take a look at Linq-to-Excel. It's pretty neat.

var book = new LinqToExcel.ExcelQueryFactory(@"File.xlsx");

var query =
    from row in book.Worksheet("Stock Entry")
    let item = new
    {
        Code = row["Code"].Cast<string>(),
        Supplier = row["Supplier"].Cast<string>(),
        Ref = row["Ref"].Cast<string>(),
    }
    where item.Supplier == "Walmart"
    select item;

It also allows for strongly-typed row access too.

Remove all br tags and use display: table.

.text span {
   background: rgba(165, 220, 79, 0.8);
   display: table;
   padding: 7px 10px;
   color: white;
}
.fullscreen .large { font-size: 80px }

Explanation: The table wraps the width of its content by default without setting a width, but is still a block level element. You can get the same behavior by setting a width to other block-level elements:

<span style="display:block;border:1px solid red;width:100px;">Like a default table.</span>
<code>null</code>

Notice the <code> element doesn't flow inline with the <span> like it would normally. Check it out with the computed styles in your dev tools. You'll see pseudo margin to the right of the <span>. Anyway, this is the same as the table, but the table has the added benefit of always forming to the width of its content.

In that version of Android, when a view is inflated, the focus will be set to the first focusable control by default - and if there's no physical keyboard, the on-screen keyboard will pop up.

To fix this, explicitly set focus somewhere else. If focus is set to anything other than an EditText, the on-screen keyboard will not appear.

Have you tried testing this by running Android 1.5 in the emulator?

You should export an array like this:

const path = require('path');
const webpack = require('webpack');

const libName = 'YourLibraryName';

function getConfig(env) {
  const config = {
    mode: env,
    output: {
      path: path.resolve('dist'),
      library: libName,
      libraryTarget: 'umd',
      filename: env === 'production' ? `${libName}.min.js` : `${libName}.js`
    },
    target: 'web',
    .... your shared options ...
  };

  return config;
}

module.exports = [
  getConfig('development'),
  getConfig('production'),
];

I used to use this function. its safe, quick, easily maintainable.

def deep_get(dictionary, keys, default=None):
    return reduce(lambda d, key: d.get(key, default) if isinstance(d, dict) else default, keys.split("."), dictionary)

Example :

>>> from functools import reduce
>>> def deep_get(dictionary, keys, default=None):
...     return reduce(lambda d, key: d.get(key, default) if isinstance(d, dict) else default, keys.split("."), dictionary)
...
>>> person = {'person':{'name':{'first':'John'}}}
>>> print (deep_get(person, "person.name.first"))
John
>>> print (deep_get(person, "person.name.lastname"))
None
>>> print (deep_get(person, "person.name.lastname", default="No lastname"))
No lastname
>>>

Calling .html() serializes the element to a string, so all event handlers and other associated data is lost. Here's how I'd do it:

$("#myButton").click(function ()
{
    var test = $('<button/>',
    {
        text: 'Test',
        click: function () { alert('hi'); }
    });

    var parent = $('<tr><td></td></tr>').children().append(test).end();

    $("#addNodeTable tr:last").before(parent);
});

Or,

$("#myButton").click(function ()
{    
    var test = $('<button/>',
    {
        text: 'Test',
        click: function () { alert('hi'); }
    }).wrap('<tr><td></td></tr>').closest('tr');

    $("#addNodeTable tr:last").before(test);
});

If you don't like passing a map of properties to $(), you can instead use

$('<button/>')
    .text('Test')
    .click(function () { alert('hi'); });

// or

$('<button>Test</button>').click(function () { alert('hi'); });

$('.checkall').change(function() {
    var checkboxes = $(this).closest('table').find('td').find(':checkbox');
    if($(this).is(':checked')) {
        checkboxes.attr('checked', 'checked');
    } else {
        checkboxes.removeAttr('checked');
    }
});

Just to make use of updated solution try using lodash utility https://lodash.com/docs#get

Easy way to get this working is using:

var cloneArray = JSON.parse(JSON.stringify(originalArray));

I have issues with getting arr.concat() or arr.splice(0) to give a deep copy. Above snippet works perfectly.

Simple, without any other API:

To add 8 days:

Date today=new Date();
long ltime=today.getTime()+8*24*60*60*1000;
Date today8=new Date(ltime);

There are some solutions, make sure to check them all :)

The router outlet will emit the activate event any time a new component is being instantiated, so we could use (activate) to scroll (for example) to the top:

app.component.html

<router-outlet (activate)="onActivate($event)" ></router-outlet>

app.component.ts

onActivate(event) {
    window.scroll(0,0);
    //or document.body.scrollTop = 0;
    //or document.querySelector('body').scrollTo(0,0)
    ...
}

Use, for exemple, this solution for a smooth scroll:

    onActivate(event) {
        let scrollToTop = window.setInterval(() => {
            let pos = window.pageYOffset;
            if (pos > 0) {
                window.scrollTo(0, pos - 20); // how far to scroll on each step
            } else {
                window.clearInterval(scrollToTop);
            }
        }, 16);
    }

If you wish to be selective, say not every component should trigger the scrolling, you can check it in an if statement like this:

onActivate(e) {
    if (e.constructor.name)==="login"{ // for example
            window.scroll(0,0);
    }
}

Since Angular6.1, we can also use { scrollPositionRestoration: 'enabled' } on eagerly loaded modules and it will be applied to all routes:

RouterModule.forRoot(appRoutes, { scrollPositionRestoration: 'enabled' })

It will also do the smooth scrolling, already. However this has the inconvenient for doing it on every routing.

An other solution is to do the top scrolling on router animation. Add this in every transition where you want to scroll to the top:

query(':enter, :leave', style({ position: 'fixed' }), { optional: true }) 

To automate the answer of @Jordan S. Jones at WIN/DOS command-line,

Put this in a batch file named: getmns.bat (get mail name server):

@echo off
if @%1==@ goto USAGE
echo set type=MX>mnscmd.txt
echo %1>>mnscmd.txt
echo exit>>mnscmd.txt
nslookup<mnscmd.txt>mnsresult.txt
type mnsresult.txt
del mnsresult.txt
goto END
:USAGE
echo usage:
echo %0 domainname.ext
:END
echo.

For example:

getmns google.com

output:

google.com      MX preference = 20, mail exchanger = alt1.aspmx.l.google.com
google.com      MX preference = 10, mail exchanger = aspmx.l.google.com
google.com      MX preference = 50, mail exchanger = alt4.aspmx.l.google.com
google.com      MX preference = 40, mail exchanger = alt3.aspmx.l.google.com
google.com      MX preference = 30, mail exchanger = alt2.aspmx.l.google.com

alt4.aspmx.l.google.com internet address = 74.125.25.27
alt3.aspmx.l.google.com internet address = 173.194.72.27
aspmx.l.google.com      internet address = 173.194.65.27
alt1.aspmx.l.google.com internet address = 74.125.200.27
alt2.aspmx.l.google.com internet address = 64.233.187.27

For example to pipe the result again into a file do:

getmns google.com > google.mns.txt

Use TO_TIMESTAMP function

TO_TIMESTAMP(date_string,'YYYY-MM-DD HH24:MI:SS')

This can de done in a relatively elegant way using SELECT DISTINCT, as follows:

SELECT DISTINCT ON (sensorID)
sensorID, timestamp, sensorField1, sensorField2 
FROM sensorTable
ORDER BY sensorID, timestamp DESC;

The above works for PostgreSQL (some more info here) but I think also other engines. In case it's not obvious, what this does is sort the table by sensor ID and timestamp (newest to oldest), and then returns the first row (i.e. latest timestamp) for each unique sensor ID.

In my use case I have ~10M readings from ~1K sensors, so trying to join the table with itself on a timestamp-based filter is very resource-intensive; the above takes a couple of seconds.

Note that if there are ties in top 10 values, you will only get the top 10 rows, not the top 10 values with the answers provided. Ex: if the top 5 values are 10, 11, 12, 13, 14, 15 but your data contains 10, 10, 11, 12, 13, 14, 15 you will only get 10, 10, 11, 12, 13, 14 as your top 5 with a LIMIT

Here is a solution which will return more than 10 rows if there are ties but you will get all the rows where some_value_column is technically in the top 10.

select
  *
from
  (select
     *,
     rank() over (order by some_value_column desc) as my_rank
  from mytable) subquery
where my_rank <= 10

If you have recently installed Java 8 and uninstalled Java 7, install JDK 8 and retry.

if use JPA I recommend change to lowercase schema, table and column names, you can use next intructions for help you:

select
    psat.schemaname,
    psat.relname,
    pa.attname,
    psat.relid
from
    pg_catalog.pg_stat_all_tables psat,
    pg_catalog.pg_attribute pa
where
    psat.relid = pa.attrelid

change schema name:

ALTER SCHEMA "XXXXX" RENAME TO xxxxx;

change table names:

ALTER TABLE xxxxx."AAAAA" RENAME TO aaaaa;

change column names:

ALTER TABLE xxxxx.aaaaa RENAME COLUMN "CCCCC" TO ccccc;

JSP and Servlet are Server side Programming. As it comes as an built in package inside a Server like Tomcat. The path may be like wise

C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib\jsp-api.jar
C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib\servlet-api.jar

Just you want to Do is Add this in the following way

Right Click> My Computer>Advanced>Environment Variables>System variables

Do> New..> Variable name:CLASSPATH
           Variable value:CLASSPATH=.;C:\Program Files\Apache Software Foundation\Tomcat 6.0\lib\servlet-api.jar;

I'm using SSH to authenticate my GitHub account and have a couple dependencies in my project installed as follows:

Sample code to get image links within HTML content. Like preg_match_all in PHP

let HTML = '<div class="imageset"><table><tbody><tr><td width="50%"><img src="htt ps://domain.com/uploads/monthly_2019_11/7/1.png.jpg" class="fr-fic fr-dii"></td><td width="50%"><img src="htt ps://domain.com/uploads/monthly_2019_11/7/9.png.jpg" class="fr-fic fr-dii"></td></tr></tbody></table></div>';
let re = /<img src="(.*?)"/gi;
let result = HTML.match(re);

out array

0: "<img src="htt ps://domain.com/uploads/monthly_2019_11/7/1.png.jpg""
1: "<img src="htt ps://domain.com/uploads/monthly_2019_11/7/9.png.jpg""

I'm going to add to this, as it's a search that came out top on google..

When using ExtJS / Javascript I insert this and the console is cleared out - unless there is an error..

console.log('\033[2J');

I'm more than likely way off course, but this is how I clear the console for each page load/refresh.

protected void btnExportExcel_Click(object sender, EventArgs e)
{
    DataTable _datatable = new DataTable();
    for (int i = 0; i < grdReport.Columns.Count; i++)
    {
        _datatable.Columns.Add(grdReport.Columns[i].ToString());
    }
    foreach (GridViewRow row in grdReport.Rows)
    {
        DataRow dr = _datatable.NewRow();
        for (int j = 0; j < grdReport.Columns.Count; j++)
        {
            if (!row.Cells[j].Text.Equals("&nbsp;"))
                dr[grdReport.Columns[j].ToString()] = row.Cells[j].Text;
        }

        _datatable.Rows.Add(dr);
    }
    ExportDataTableToExcel(_datatable);
}

I found this image most helpful for understanding frame, bounds, etc.

Also please note that frame.size != bounds.size when the image is rotated.

#include <iostream>
#include <string>
using namespace std;

int main()
{
    cout << stod("  99.999  ") << endl;
}

Output: 99.999 (which is double, whitespace was automatically stripped)

Since C++11 converting string to floating-point values (like double) is available with functions:
stof - convert str to a float
stod - convert str to a double
stold - convert str to a long double

As conversion of string to int was also mentioned in the question, there are the following functions in C++11:
stoi - convert str to an int
stol - convert str to a long
stoul - convert str to an unsigned long
stoll - convert str to a long long
stoull - convert str to an unsigned long long

If you have to do a curl in php, you should use urlencode() from PHP but individually!

strPOST = "Item1=" . $Value1 . "&Item2=" . urlencode("+")

If you do urlencode(strPOST), you will bring you another problem, you will have one Item1 and & will be change %xx value and be as one value, see down here the return!

Example 1

$strPOST = "Item1=" . $Value1 . "&Item2=" . urlencode("+") will give Item1=Value1&Item2=%2B

Example 2

$strPOST = urlencode("Item1=" . $Value1 . "&Item2=+") will give Item1%3DValue1%26Item2%3D%2B

Example 1 is the good way to prepare string for POST in curl

Example 2 show that the receptor will not see the equal and the ampersand to distinguish both value!

Yes. HTML2Canvas exists to render HTML onto <canvas> (which you can then use as an image).

NOTE: There is a known issue, that this will not work with SVG

Use cd in a subshell; the shorthand way to use this kind of subshell is parentheses.

(cd wherever; mycommand ...)

That said, if your command has an environment that it requires, it should really ensure that environment itself instead of putting the onus on anything that might want to use it (unless it's an internal command used in very specific circumstances in the context of a well defined larger system, such that any caller already needs to ensure the environment it requires). Usually this would be some kind of shell script wrapper.

Realizing that the question is old and one answer is accepted, I'll provide another answer for reference.

scale is limited by the fact that it scales all variables. The solution below allows to scale only specific variable names while preserving other variables unchanged (and the variable names could be dynamically generated):

library(dplyr)

set.seed(1234)
dat <- data.frame(x = rnorm(10, 30, .2), 
                  y = runif(10, 3, 5),
                  z = runif(10, 10, 20))
dat

dat2 <- dat %>% mutate_at(c("y", "z"), ~(scale(.) %>% as.vector))
dat2

which gives me this:

> dat
          x        y        z
1  29.75859 3.633225 14.56091
2  30.05549 3.605387 12.65187
3  30.21689 3.318092 13.04672
4  29.53086 3.079992 15.07307
5  30.08582 3.437599 11.81096
6  30.10121 4.621197 17.59671
7  29.88505 4.051395 12.01248
8  29.89067 4.829316 12.58810
9  29.88711 4.662690 19.92150
10 29.82199 3.091541 18.07352

and

> dat2 <- dat %>% mutate_at(c("y", "z"), ~(scale(.) %>% as.vector))
> dat2
          x          y           z
1  29.75859 -0.3004815 -0.06016029
2  30.05549 -0.3423437 -0.72529604
3  30.21689 -0.7743696 -0.58772361
4  29.53086 -1.1324181  0.11828039

6  30.10121  1.1852038  0.99754666
7  29.88505  0.3283513 -0.94806607
8  29.89067  1.4981677 -0.74751378
9  29.88711  1.2475998  1.80753470
10 29.82199 -1.1150515  1.16367556

EDIT 1 (2016): Addressed Julian's comment: the output of scale is Nx1 matrix so ideally we should add an as.vector to convert the matrix type back into a vector type. Thanks Julian!

EDIT 2 (2019): Quoting Duccio A.'s comment: For the latest dplyr (version 0.8) you need to change dplyr::funcs with list, like dat %>% mutate_each_(list(~scale(.) %>% as.vector), vars=c("y","z"))

EDIT 3 (2020): Thanks to @mj_whales: the old solution is deprecated and now we need to use mutate_at.

How would I accomplish the nextsibling and is there an easier way of doing this?

You may use:

tr/td[@class='name']/following-sibling::td

but I'd rather use directly:

tr[td[@class='name'] ='Brand']/td[@class='desc']

This assumes that:

1. The context node, against which the XPath expression is evaluated is the parent of all tr elements -- not shown in your question.

2. Each tr element has only one td with class attribute valued 'name' and only one td with class attribute valued 'desc'.

There are some tools and API's available for it. However, I do not think you'll find one for free ;)

There is for instance the OLicense suite: http://www.olicense.de/index.php?lang=en

You can use Entry class to read HashMap easily.

for(Map.Entry<TypeKey, TypeKey> temp : example.entrySet()){
    System.out.println(temp.getValue()); // Or something as per temp defination. can be used
}

In case anybody is here and the other two solutions do not make the trick, check that what you are using to filter is what you expect:

user = UniversityDetails.objects.get(email=email)

is email a str, or a None? or an int?

Most of the answers are using a loop to go through the items. Here I have a variant that is using an EAFP way to do things: try to get an iterator on your input, if it succeeds run your function first on the first element, next on the remainder of this iterator. If you can't get an iterator, or if it's a string or a bytes object: yield the element.

Thanks to the suggestion from A. Kareem, who found out that my code was very slow, due to the fact that the recursion took too long for string and byte objects, here is an improved version of my code.

def flatten(x, it = None):
    try:
        if type(x) in (str, bytes):
            yield x
        else:
            if not it:
                it = iter(x)
            yield from flatten(next(it))
        if type(x) not in (str, bytes):
            yield from flatten(x, it)
    except StopIteration:
        pass
    except Exception:
        yield x

oldlist = [1,[[[["test",3]]]],((4,5,6)),[ bytes("test", encoding="utf-8"),7,[8,9]]]
newlist = [ x for x in flatten(oldlist) ]
print(newlist)
# [1, 'test', 3, 4, 5, 6, b'test', 7, 8, 9]

My pseudocode example will be as follows:

JSONArray jsonArray = "[{id:\"1\", name:\"sql\"},{id:\"2\",name:\"android\"},{id:\"3\",name:\"mvc\"}]";
JSON newJson = new JSON();

for (each json in jsonArray) {
    String id = json.get("id");
    String name = json.get("name");

    newJson.put(id, name);
}

return newJson;

Yes.

You could create a custom tag as such:

<html>
<head>
<style>
vr {
display: inline-block;
// This is where you'd set the ruler color
background-color: black;
// This is where you'd set the ruler width
width: 2px;
//this is where you'd set the spacing between the ruler and surrounding text
margin: 0px 5px 0px 5px;
height: 100%;
vertical-align: top;
}
</style>
</head>
<body>
this is text <vr></vr> more text
</body>
</html>

(If anyone knows a way that I could turn this into an "open-ended" tag, like <hr> let me know and I will edit it in)

I found this question looking for a way to do the same thing for my Javascript tests, using Protractor (a javascript frontend to Selenium.)

My solution with protractor 1.2.0 and webdriver 2.1:

browser.actions()
.mouseMove(
  element(by.css('.material-dialog-container'))
)
.click()
.perform();

This also accepts an offset (i'm using it to click above and left of an element:)

browser.actions()
.mouseMove(
  element(by.css('.material-dialog-container'))
  , -20, -20  // pixel offset from top left
)
.click()
.perform();

Suppose I create a new file, newFile.txt:

Suppose I add the file accidentally, git add newFile.txt:

Now I want to undo this add, before commit, git reset newFile.txt:

Try this:

<marquee behavior="" Height="200px"  direction="up" scroll onmouseover="this.setAttribute('scrollamount', 0, 0);this.stop();" onmouseout="this.setAttribute('scrollamount', 3, 0);this.start();" scrollamount="3" valign="center">

    <img src="images/a.jpg">
        <img src="images/a.jpg">
        <img src="images/a.jpg">
        <img src="images/a.jpg">
        <img src="images/a.jpg">
        <img src="images/a.jpg">
    </marquee>

Can you try this?

- (void)tableView:(UITableView *)tableView 
  didSelectRowAtIndexPath:(NSIndexPath *)indexPath {

    AppDelegate_iPad *appDelegte = 
    (AppDelegate_iPad *)[[UIApplication sharedApplication] delegate];
    NSIndexPath *indexpath1 = appDelegte.indexPathDelegate;
    appDelegte.indexPathDelegate = indexPath;

    UITableViewCell *prevSelectedCell = [tableView cellForRowAtIndexPath: indexpath1];
    if([prevSelectedCell isSelected]){
       [prevSelectedCell setSelected:NO];
    }
}

It worked for me.

If you have successfully installed Apache web server and Perl please follow the following steps to run cgi script using perl on ubuntu systems.

Before starting with CGI scripting it is necessary to configure apache server in such a way that it recognizes the CGI directory (where the cgi programs are saved) and allow for the execution of programs within that directory.

1. In Ubuntu cgi-bin directory usually resides in path /usr/lib , if not present create the cgi-bin directory using the following command.cgi-bin should be in this path itself.

    mkdir /usr/lib/cgi-bin
   

2. Issue the following command to check the permission status of the directory.

    ls -l /usr/lib | less
   

Check whether the permission looks as “drwxr-xr-x 2 root root 4096 2011-11-23 09:08 cgi- bin” if yes go to step 3.

If not issue the following command to ensure the appropriate permission for our cgi-bin directory.

     sudo chmod 755 /usr/lib/cgi-bin
     sudo chmod root.root /usr/lib/cgi-bin

3. Give execution permission to cgi-bin directory

    sudo chmod 755 /usr/lib/cgi-bin
   

Thus your cgi-bin directory is ready to go. This is where you put all your cgi scripts for execution. Our next step is configure apache to recognize cgi-bin directory and allow execution of all programs in it as cgi scripts.

Configuring Apache to run CGI script using perl

1. A directive need to be added in the configuration file of apache server so it knows the presence of CGI and the location of its directories. Initially go to location of configuration file of apache and open it with your favorite text editor

   cd /etc/apache2/sites-available/ 
   sudo gedit 000-default.conf
   

2. Copy the below content to the file 000-default.conf between the line of codes “DocumentRoot /var/www/html/” and “ErrorLog $ {APACHE_LOG_DIR}/error.log”

   ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
   <Directory "/usr/lib/cgi-bin">
   AllowOverride None
   Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
   Require all granted
   

3. Restart apache server with the following code

   sudo service apache2 restart
   

4. Now we need to enable cgi module which is present in newer versions of ubuntu by default

   sudo a2enmod cgi.load
   sudo a2enmod cgid.load
   

5. At this point we can reload the apache webserver so that it reads the configuration files again.

   sudo service apache2 reload
   

The configuration part of apache is over now let us check it with a sample cgi perl program.

Testing it out

1. Go to the cgi-bin directory and create a cgi file with extension .pl

   cd /usr/lib/cgi-bin/
   sudo gedit test.pl
   

2. Copy the following code on test.pl and save it.

   #!/usr/bin/perl -w
   print “Content-type: text/html\r\n\r\n”;
   print “CGI working perfectly!! \n”;
   

3. Now give the test.pl execution permission.

   sudo chmod 755 test.pl
   

4. Now open that file in your web browser http://Localhost/cgi-bin/test.pl

5. If you see the output “CGI working perfectly” you are ready to go.Now dump all your programs into the cgi-bin directory and start using them.

NB: Don't forget to give your new programs in cgi-bin, chmod 755 permissions so as to run it successfully without any internal server errors.

Since it is not yet supported using angular CLI

so here is the possible way, before that please observe what happens when you create a component/service using CLI (ex. ng g c demoComponent).

1. It creates a separate folder named demoComponent (ng g c demoComponent).
2. It generate HTML,CSS,ts and a spec file dedicated to demoComponent.
3. Also, It adds dependency inside app.module.ts file to add that component to your project.

so do it in reverse order

1. Remove Dependency from app.module.ts
2. Delete that component folder.

when removing the dependency you have to do two things.

1. Remove the import line reference from app.module.ts file.
2. Remove the component declaration from @NgModule declaration array in app.module.ts.

In Matlab, you can iterate over the elements in the list directly. This can be useful if you don't need to know which element you're currently working on.

Thus you can write

for elm = list
%# do something with the element
end

Note that Matlab iterates through the columns of list, so if list is a nx1 vector, you may want to transpose it.

StringUtils is an Apache Commons project. You need to download and add the library to your classpath.

To use:

import org.apache.commons.lang3.StringUtils;

In my case the file probably got deleted somehow. I just went to the SVN repository and reverted to the file.

If you have a command window open and call the commands manually, you can display a timestamp on each prompt, e.g.

prompt $d $t $_$P$G

It gives you something like:

23.03.2009 15:45:50,77

C:\>

If you have a small batch script that executes your commands, have an empty line before each command, e.g.

(empty line)

myCommand.exe

(next empty line)

myCommand2.exe

You can calculate the execution time for each command by the time information in the prompt. The best would probably be to pipe the output to a textfile for further analysis:

MyBatchFile.bat > output.txt

You can use:

@foreach (var item in Model)
{
  ...
  @Html.DisplayFor(modelItem => item.address + " " + item.city) 
  ...

I had this problem suddenly crop up in Windows 7 with my Nexus One - somehow the USB drivers had been uninstalled. I ran android-sdk/SDK Manager.exe, checked Extras/Google USB Driver and installed it. Then I unplugged the phone and plugged it back in, and ran "adb devices" to confirm the phone was attached.

This doesn't work for all phones, just the ones listed here: http://developer.android.com/sdk/win-usb.html

From HandlerIntercepter's javadoc:

HandlerInterceptor is basically similar to a Servlet Filter, but in contrast to the latter it just allows custom pre-processing with the option of prohibiting the execution of the handler itself, and custom post-processing. Filters are more powerful, for example they allow for exchanging the request and response objects that are handed down the chain. Note that a filter gets configured in web.xml, a HandlerInterceptor in the application context.

As a basic guideline, fine-grained handler-related pre-processing tasks are candidates for HandlerInterceptor implementations, especially factored-out common handler code and authorization checks. On the other hand, a Filter is well-suited for request content and view content handling, like multipart forms and GZIP compression. This typically shows when one needs to map the filter to certain content types (e.g. images), or to all requests.

With that being said:

So where is the difference between Interceptor#postHandle() and Filter#doFilter()?

postHandle will be called after handler method invocation but before the view being rendered. So, you can add more model objects to the view but you can not change the HttpServletResponse since it's already committed.

doFilter is much more versatile than the postHandle. You can change the request or response and pass it to the chain or even block the request processing.

Also, in preHandle and postHandle methods, you have access to the HandlerMethod that processed the request. So, you can add pre/post-processing logic based on the handler itself. For example, you can add a logic for handler methods that have some annotations.

What is the best practise in which use cases it should be used?

As the doc said, fine-grained handler-related pre-processing tasks are candidates for HandlerInterceptor implementations, especially factored-out common handler code and authorization checks. On the other hand, a Filter is well-suited for request content and view content handling, like multipart forms and GZIP compression. This typically shows when one needs to map the filter to certain content types (e.g. images), or to all requests.

Try this one:

Window.function_exists=function(function_name,scope){
//Setting default scope of none is provided
If(typeof scope === 'undefined') scope=window;
//Checking if function name is defined
If (typeof function_name === 'undefined') throw new 
Error('You have to provide an valid function name!');
//The type container
var fn= (typeof scope[function_name]);
//Function type
If(fn === 'function') return true;
//Function object type
if(fn.indexOf('function')!== false) return true; 
return false;
}

Be aware that I've write this with my cellphone Might contain some uppercase issues and/or other corrections needed like for example functions name

If you want a function like PHP to check if the var is set:

Window.isset=function (variable_con){
If(typeof variable_con !== 'undefined') return true;
return false;
}

I had this problem as well.

My problem was that I had copy/pasted the library include directories from my debug configurations.

So project "Indep" was including static library "Dep.lib" from "../Debug", even in release. The fix was to change the library directory to "../Release" so I caught the release-built library rather than the previously-built debug library.

The Android SDK doesn't come with any easy way to draw text on OpenGL views. Leaving you with the following options.

1. Place a TextView over your SurfaceView. This is slow and bad, but the most direct approach.
2. Render common strings to textures, and simply draw those textures. This is by far the simplest and fastest, but the least flexible.
3. Roll-your-own text rendering code based on a sprite. Probably second best choice if 2 isn't an option. A good way to get your feet wet but note that while it seems simple (and basic features are), it get's harder and more challenging as you add more features (texture-alignment, dealing with line-breaks, variable-width fonts etc.) - if you take this route, make it as simple as you can get away with!
4. Use an off-the-shelf/open-source library. There are a few around if you hunt on Google, the tricky bit is getting them integrated and running. But at least, once you do that, you'll have all the flexibility and maturity they provide.

I use ngProgress for this.

Add 'ngProgress' to your dependencies once you've included the script/css files in your HTML. Once you do that you can set up something like this, which will trigger when a route change was detected.

angular.module('app').run(function($rootScope, ngProgress) {
  $rootScope.$on('$routeChangeStart', function(ev,data) {
    ngProgress.start();
  });
  $rootScope.$on('$routeChangeSuccess', function(ev,data) {
    ngProgress.complete();
  });
});

For AJAX requests you can do something like this:

$scope.getLatest = function () {
    ngProgress.start();

    $http.get('/latest-goodies')
         .success(function(data,status) {
             $scope.latest = data;
             ngProgress.complete();
         })
         .error(function(data,status) {
             ngProgress.complete();
         });
};

Just remember to add 'ngProgress' to the controllers dependencies before doing so. And if you are doing multiple AJAX requests use an incremental variable in the main app scope to keep track when your AJAX requests have finished before calling 'ngProgress.complete();'.

Variables are declared and assigned without $ and without {}. You have to use

var=10

to assign. In order to read from the variable (in other words, 'expand' the variable), you must use $.

$var      # use the variable
${var}    # same as above
${var}bar # expand var, and append "bar" too
$varbar   # same as ${varbar}, i.e expand a variable called varbar, if it exists.

This has confused me sometimes - in other languages we refer to the variable in the same way, regardless of whether it's on the left or right of an assignment. But shell-scripting is different, $var=10 doesn't do what you might think it does!

@NoCanDo: You cannot create an array with different data types because java only supports variables with a specific data type or object. When you are creating an array, you are pulling together an assortment of similar variables -- almost like an extended variable. All of the variables must be of the same type therefore. Java cannot differentiate the data type of your variable unless you tell it what it is. Ex: int tells all your variables declared to it are of data type int. What you could do is create 3 arrays with corresponding information.

Now, a single index number gives you all the info for that book. Ex: All of your arrays with index number 0 ([0]) have information for book 1.

You can also set figure size by passing dictionary to rc parameter with key 'figure.figsize' in seaborn set method:

import seaborn as sns

sns.set(rc={'figure.figsize':(11.7,8.27)})

Other alternative may be to use figure.figsize of rcParams to set figure size as below:

from matplotlib import rcParams

# figure size in inches
rcParams['figure.figsize'] = 11.7,8.27

More details can be found in matplotlib documentation

Even though the following will not satisfy this request (the function json_object_agg is not available in PostgreSQL 9.3), the following can be useful for anyone looking for a || operator for PostgreSQL 9.4, as implemented in the upcoming PostgreSQL 9.5:

CREATE OR REPLACE FUNCTION jsonb_merge(left JSONB, right JSONB)
RETURNS JSONB
AS $$
SELECT
  CASE WHEN jsonb_typeof($1) = 'object' AND jsonb_typeof($2) = 'object' THEN
       (SELECT json_object_agg(COALESCE(o.key, n.key), CASE WHEN n.key IS NOT NULL THEN n.value ELSE o.value END)::jsonb
        FROM jsonb_each($1) o
        FULL JOIN jsonb_each($2) n ON (n.key = o.key))
   ELSE 
     (CASE WHEN jsonb_typeof($1) = 'array' THEN LEFT($1::text, -1) ELSE '['||$1::text END ||', '||
      CASE WHEN jsonb_typeof($2) = 'array' THEN RIGHT($2::text, -1) ELSE $2::text||']' END)::jsonb
   END     
$$ LANGUAGE sql IMMUTABLE STRICT;
GRANT EXECUTE ON FUNCTION jsonb_merge(jsonb, jsonb) TO public;
CREATE OPERATOR || ( LEFTARG = jsonb, RIGHTARG = jsonb, PROCEDURE = jsonb_merge );

IIF is the same as CASE WHEN <Condition> THEN <true part> ELSE <false part> END. The query plan will be the same. It is, perhaps, "syntactical sugar" as initially implemented.

CASE is portable across all SQL platforms whereas IIF is SQL SERVER 2012+ specific.

The fact that GitHub changed master to main made me encounter this issue. So from now on, the solution to push to origin is:

git push -u origin main

Change the cell type to Markdown in the menu bar, from Code to Markdown. Currently in Notebook 4.x, the keyboard shortcut for such an action is: Esc (for command mode), then m (for markdown).

Try doing this:

• Unplug the device
• Execute adb kill-server && adb start-server(that restarts adb)
• Re-plug the device

Also you can try to edit an adb config file .android/adb_usb.ini and add a line 04e8 after the header. Restart adb required for changes to take effect.

If you are looking to remove usernames and passwords from your docker-compose.yml you can use Docker Secrets, here is how I have approached it.

version: '3.6'

services:
  db:
    image: mongo:3
    container_name: mycontainer
  secrets:
    - MONGO_INITDB_ROOT_USERNAME
    - MONGO_INITDB_ROOT_PASSWORD
  environment:
    - MONGO_INITDB_ROOT_USERNAME_FILE=/var/run/secrets/MONGO_INITDB_ROOT_USERNAME
    - MONGO_INITDB_ROOT_PASSWORD_FILE=/var/run/secrets/MONGO_INITDB_ROOT_PASSWORD
secrets:
  MONGO_INITDB_ROOT_USERNAME:
    file:  secrets/${NODE_ENV}_mongo_root_username.txt
  MONGO_INITDB_ROOT_PASSWORD:
    file:  secrets/${NODE_ENV}_mongo_root_password.txt

I have use the file: option for my secrets however, you can also use external: and use the secrets in a swarm.

The secrets are available to any script in the container at /var/run/secrets

The Docker documentation has this to say about storing sensitive data...

https://docs.docker.com/engine/swarm/secrets/

You can use secrets to manage any sensitive data which a container needs at runtime but you don’t want to store in the image or in source control, such as:

Usernames and passwords TLS certificates and keys SSH keys Other important data such as the name of a database or internal server Generic strings or binary content (up to 500 kb in size)

The way to do this in 2019+ is to use DeviceOrientation API. This works in most modern browsers on desktop and mobile.

window.addEventListener("deviceorientation", handleOrientation, true);

After registering your event listener (in this case, a JavaScript function called handleOrientation()), your listener function periodically gets called with updated orientation data.

The orientation event contains four values:

• DeviceOrientationEvent.absolute
• DeviceOrientationEvent.alpha
• DeviceOrientationEvent.beta
• DeviceOrientationEvent.gamma

The event handler function can look something like this:

function handleOrientation(event) {
  var absolute = event.absolute;
  var alpha    = event.alpha;
  var beta     = event.beta;
  var gamma    = event.gamma;
  // Do stuff with the new orientation data
}

Came across this problem myself and in the end wrote a small library cloneable-ts that provides an abstract class, which adds a clone method to any class extending it. The abstract class borrows the Deep Copy Function described in the accepted answer by Fenton only replacing copy = {}; with copy = Object.create(originalObj) to preserve the class of the original object. Here is an example of using the class.

import {Cloneable, CloneableArgs} from 'cloneable-ts';

// Interface that will be used as named arguments to initialize and clone an object
interface PersonArgs {
    readonly name: string;
    readonly age: number;
}

// Cloneable abstract class initializes the object with super method and adds the clone method
// CloneableArgs interface ensures that all properties defined in the argument interface are defined in class
class Person extends Cloneable<TestArgs>  implements CloneableArgs<PersonArgs> {
    readonly name: string;
    readonly age: number;

    constructor(args: TestArgs) {
        super(args);
    }
}

const a = new Person({name: 'Alice', age: 28});
const b = a.clone({name: 'Bob'})
a.name // Alice
b.name // Bob
b.age // 28

Or you could just use the Cloneable.clone helper method:

import {Cloneable} from 'cloneable-ts';

interface Person {
    readonly name: string;
    readonly age: number;
}

const a: Person = {name: 'Alice', age: 28};
const b = Cloneable.clone(a, {name: 'Bob'})
a.name // Alice
b.name // Bob
b.age // 28    

This problem happened with me and sovled by just add

 respond_to :html, :json

to ApplicationController file

You can Check Devise issues on Github: https://github.com/plataformatec/devise/issues/2667

With SQL server you can use this

SELECT CONVERT(VARCHAR(10), GETDATE(), 101) AS [MM/DD/YYYY];

with mysql server you can do the following

SELECT * FROM my_table WHERE YEAR(date_field) = '2006' AND MONTH(date_field) = '9' AND DAY(date_field) = '11'

I use the following command in order to remove conflict using command line

svn revert "location of conflict folder" -R
svn cleanup
svn update

for reverting current directory

svn revert . -R

I solved this problem like this.

1. setImage to UIImageView (with UIViewContentModeScaleAspectFit)
2. get imageSize (CGSize imageSize = imageView.image.size)
3. UIImageView resize. [imageView sizeThatFits:imageSize]
4. move position where you want.

I wanted to put UIView on the top center of UICollectionViewCell. so, I used this function.

- (void)setImageToCenter:(UIImageView *)imageView
{
    CGSize imageSize = imageView.image.size;
    [imageView sizeThatFits:imageSize];
    CGPoint imageViewCenter = imageView.center;
     imageViewCenter.x = CGRectGetMidX(self.contentView.frame);
    [imageView setCenter:imageViewCenter];
}

It works for me.

To find an ancestor of a given type from code, you can use:

[CanBeNull]
public static T FindAncestor<T>(DependencyObject d) where T : DependencyObject
{
    while (true)
    {
        d = VisualTreeHelper.GetParent(d);

        if (d == null)
            return null;

        var t = d as T;

        if (t != null)
            return t;
    }
}

This implementation uses iteration instead of recursion which can be slightly faster.

If you're using C# 7, this can be made slightly shorter:

[CanBeNull]
public static T FindAncestor<T>(DependencyObject d) where T : DependencyObject
{
    while (true)
    {
        d = VisualTreeHelper.GetParent(d);

        if (d == null)
            return null;

        if (d is T t)
            return t;
    }
}

This works fine for all browsers:

-webkit-box-shadow: -7px 0px 10px 0px #000, 7px 0px 10px 0px #000;
-moz-box-shadow: -7px 0px 10px 0px #000, 7px 0px 10px 0px #000;
box-shadow: -7px 0px 10px 0px #000, 7px 0px 10px 0px #000;

Here is what i tried to do to add parameter in the url which contain the specific character in the url.

jQuery('a[href*="google.com"]').attr('href', function(i,href) {
        //jquery date addition
        var requiredDate = new Date();
        var numberOfDaysToAdd = 60;
        requiredDate.setDate(requiredDate.getDate() + numberOfDaysToAdd); 
        //var convertedDate  = requiredDate.format('d-M-Y');
        //var newDate = datepicker.formatDate('yy/mm/dd', requiredDate );
        //console.log(requiredDate);

        var month   = requiredDate.getMonth()+1;
        var day     = requiredDate.getDate();

        var output = requiredDate.getFullYear() + '/' + ((''+month).length<2 ? '0' : '') + month + '/' + ((''+day).length<2 ? '0' : '') + day;

We don't need to plt.ioff() or plt.show() (if we use %matplotlib inline). You can test above code without plt.ioff(). plt.close() has the essential role. Try this one:

%matplotlib inline
import pylab as plt

# It doesn't matter you add line below. You can even replace it by 'plt.ion()', but you will see no changes.
## plt.ioff()

# Create a new figure, plot into it, then close it so it never gets displayed
fig = plt.figure()
plt.plot([1,2,3])
plt.savefig('test0.png')
plt.close(fig)

# Create a new figure, plot into it, then don't close it so it does get displayed
fig2 = plt.figure()
plt.plot([1,3,2])
plt.savefig('test1.png')

If you run this code in iPython, it will display a second plot, and if you add plt.close(fig2) to the end of it, you will see nothing.

In conclusion, if you close figure by plt.close(fig), it won't be displayed.

For initial array, better use object instead of array, as then you won't be worrying about the indexes and it will be much more clear what is what:

const initialArr = [{
    color: "blue",
    text: "text1"
}, {
    color: "red",
    text: "text2"
}];

For actual mapping, use JS Array map instead of for loop - for loop should be used in cases when there's no actual array defined, like displaying something a certain number of times:

onPress = () => {
    ...
};

renderButtons() {
    return initialArr.map((item) => {
        return (
            <Button 
                style={{ borderColor: item.color }}
                onPress={this.onPress}
            >
                {item.text}
            </Button>
        );
    });
}

...

render() {
    return (
        <View style={...}>
            {
                this.renderButtons()
            }
        </View>
    )
}

I moved the mapping to separate function outside of render method for more readable code. There are many other ways to loop through list of elements in react native, and which way you'll use depends on what do you need to do. Most of these ways are covered in this article about React JSX loops, and although it's using React examples, everything from it can be used in React Native. Please check it out if you're interested in this topic!

Also, not on the topic on the looping, but as you're already using the array syntax for defining the onPress function, there's no need to bind it again. This, again, applies only if the function is defined using this syntax within the component, as the arrow syntax auto binds the function.

How about

if value in my_array[:, col_num]:
    do_whatever

Edit: I think __contains__ is implemented in such a way that this is the same as @detly's version

HTML code

<div ng-app>
<div ng-controller='ctrl'>
    <div ng-class='whatClassIsIt(call.state[0])'>{{call.state[0]}}</div>
    <div ng-class='whatClassIsIt(call.state[1])'>{{call.state[1]}}</div>
    <div ng-class='whatClassIsIt(call.state[2])'>{{call.state[2]}}</div>
    <div ng-class='whatClassIsIt(call.state[3])'>{{call.state[3]}}</div>

    <div ng-class='whatClassIsIt(call.state[7])'>{{call.state[7]}}</div>
</div>

JavaScript Code

function ctrl($scope){
$scope.call={state:['second','first','nothing','Never', 'Gonna', 'Give', 'You', 'Up']}


$scope.whatClassIsIt= function(someValue){
     if(someValue=="first")
            return "ClassA"
     else if(someValue=="second")
         return "ClassB";
    else
         return "ClassC";
}
}

I know this is old, but I recently faced the same issue and I managed to pick the element by accessing only the attribute like this: document.querySelector('[name="your-selector-name-here"]');

Just in case anyone would ever need this :)

According to spark documentation "where() is an alias for filter()"

filter(condition) Filters rows using the given condition. where() is an alias for filter().

Parameters: condition – a Column of types.BooleanType or a string of SQL expression.

>>> df.filter(df.age > 3).collect()
[Row(age=5, name=u'Bob')]
>>> df.where(df.age == 2).collect()
[Row(age=2, name=u'Alice')]

>>> df.filter("age > 3").collect()
[Row(age=5, name=u'Bob')]
>>> df.where("age = 2").collect()
[Row(age=2, name=u'Alice')]

I would recommend taking advantage of the fact that nodeJS will always be ES5. Remember this isn't the browser folks you can depend on the language's implementation on being stable. That said I would recommend against ever using a for-in loop in nodeJS, unless you really want to do deep recursion up the prototype chain. For simple, traditional looping I would recommend making good use of Object.keys method, in ES5. If you view the following JSPerf test, especially if you use Chrome (since it has the same engine as nodeJS), you will get a rough idea of how much more performant using this method is than using a for-in loop (roughly 10 times faster). Here's a sample of the code:

 var keys = Object.keys( obj );
 for( var i = 0,length = keys.length; i < length; i++ ) {
     obj[ keys[ i ] ];
 }

This is for Visual Studio 2019, After trying a lot of suggestions that failed to work (including changing the port number etc) I solved my problem by deleting a file that was generated on my project's root folder called "debug". As soon as this file was deleted everything started working.

You have to use querySelectorAll as you need to select all elements with the said class, again since querySelectorAll is an array you need to iterate it and add the event handlers

var deleteLinks = document.querySelectorAll('.delete');
for (var i = 0; i < deleteLinks.length; i++) {
    deleteLinks[i].addEventListener('click', function (event) {
        event.preventDefault();

        var choice = confirm("sure u want to delete?");
        if (choice) {
            return true;
        }
    });
}

October 2015 Update

This answer was posted several years ago and now the question really should be should you even consider using the X-UA-Compatible tag on your site? with the changes Microsoft has made to its browsers (more on those below).

Depending upon what Microsoft browsers you support you may not need to continue using the X-UA-Compatible tag. If you need to support IE9 or IE8, then I would recommend using the tag. If you only support the latest browsers (IE11 and/or Edge) then I would consider dropping this tag altogether. If you use Twitter Bootstrap and need to eliminate validation warnings, this tag must appear in its specified order. Additional info below:

The X-UA-Compatible meta tag allows web authors to choose what version of Internet Explorer the page should be rendered as. IE11 has made changes to these modes; see the IE11 note below. Microsoft Edge, the browser that replaced IE11, only honors the X-UA-Compatible meta tag in certain circumstances. See the Microsoft Edge note below.

According to Microsoft, when using the X-UA-Compatible tag, it should be as high as possible in your document head:

If you are using the X-UA-Compatible META tag you want to place it as close to the top of the page's HEAD as possible. Internet Explorer begins interpreting markup using the latest version. When Internet Explorer encounters the X-UA-Compatible META tag it starts over using the designated version's engine. This is a performance hit because the browser must stop and restart analyzing the content.

Here are your options:

• "IE=edge"
• "IE=11"
• "IE=EmulateIE11"
• "IE=10"
• "IE=EmulateIE10"
• "IE=9"
• "IE=EmulateIE9
• "IE=8"
• "IE=EmulateIE8"
• "IE=7"
• "IE=EmulateIE7"
• "IE=5"

To attempt to understand what each means, here are definitions provided by Microsoft:

Internet Explorer supports a number of document compatibility modes that enable different features and can affect the way content is displayed:

• Edge mode tells Internet Explorer to display content in the highest mode available. With Internet Explorer 9, this is equivalent to IE9 mode. If a future release of Internet Explorer supported a higher compatibility mode, pages set to edge mode would appear in the highest mode supported by that version. Those same pages would still appear in IE9 mode when viewed with Internet Explorer 9. Internet Explorer supports a number of document compatibility modes that enable different features and can affect the way content is displayed:

• IE11 mode provides the highest support available for established and emerging industry standards, including the HTML5, CSS3 and others.

• IE10 mode provides the highest support available for established and emerging industry standards, including the HTML5, CSS3 and others.

• IE9 mode provides the highest support available for established and emerging industry standards, including the HTML5 (Working Draft), W3C Cascading Style Sheets Level 3 Specification (Working Draft), Scalable Vector Graphics (SVG) 1.0 Specification, and others. [Editor Note: IE 9 does not support CSS3 animations].

• IE8 mode supports many established standards, including the W3C Cascading Style Sheets Level 2.1 Specification and the W3C Selectors API; it also provides limited support for the W3C Cascading Style Sheets Level 3 Specification (Working Draft) and other emerging standards.

• IE7 mode renders content as if it were displayed in standards mode by Internet Explorer 7, whether or not the page contains a directive.

• Emulate IE9 mode tells Internet Explorer to use the directive to determine how to render content. Standards mode directives are displayed in IE9 mode and quirks mode directives are displayed in IE5 mode. Unlike IE9 mode, Emulate IE9 mode respects the directive.

• Emulate IE8 mode tells Internet Explorer to use the directive to determine how to render content. Standards mode directives are displayed in IE8 mode and quirks mode directives are displayed in IE5 mode. Unlike IE8 mode, Emulate IE8 mode respects the directive.

• Emulate IE7 mode tells Internet Explorer to use the directive to determine how to render content. Standards mode directives are displayed in Internet Explorer 7 standards mode and quirks mode directives are displayed in IE5 mode. Unlike IE7 mode, Emulate IE7 mode respects the directive. For many web sites, this is the preferred compatibility mode.

• IE5 mode renders content as if it were displayed in quirks mode by Internet Explorer 7, which is very similar to the way content was displayed in Microsoft Internet Explorer 5.

IE10 NOTE: As of IE10, quirks mode behaves differently than it did in earlier versions of the browser. In IE9 and earlier versions, quirks mode restricted the webpage to the features supported by IE5.5. In IE10, quirks mode conforms to the differences specified in the HTML5 specification.

Personally, I always choose the http-equiv="X-UA-Compatible" content="IE=edge" meta tag, as older versions have plenty of bugs, and I do not want IE to decide to go into "Compatibility mode" and show my site as IE7 vs IE8 or 9. I always prefer the latest version of IE.

IE11

From Microsoft:

Starting with IE11, edge mode is the preferred document mode; it represents the highest support for modern standards available to the browser.

Use the HTML5 document type declaration to enable edge mode:

<!doctype html>

Edge mode was introduced in Internet Explorer 8 and has been available in each subsequent release. Note that the features supported by edge mode are limited to those supported by the specific version of the browser rendering the content.

Starting with IE11, document modes are deprecated and should no longer be used, except on a temporary basis. Make sure to update sites that rely on legacy features and document modes to reflect modern standards.

If you must target a specific document mode so that your site functions while you rework it to support modern standards and features, be aware that you're using a transitional feature, one that may not be available in future versions.

If you currently use the x-ua-compatible header to target a legacy document mode, it's possible your site won't reflect the best experience available with IE11.

Microsoft Edge (Replacement for Internet Explorer that comes bundled with Windows 10)

Information on X-UA-Compatible meta tag for the "Edge" version of IE. From Microsoft:

Introducing the “living” Edge document mode

As we announced in August 2013, we are deprecating document modes as of IE11. With our latest platform updates, the need for legacy document modes is primarily limited to Enterprise legacy web apps. With new architectural changes, these legacy document modes will be isolated from changes in the “living” Edge mode, which will help to guarantee a much higher level of compatibility for customers who depend on those modes and help us move even faster on improvements in Edge. IE will still honor document modes served by intranet sites, sites on the Compatibility View list, and when used with Enterprise Mode only.

Public Internet sites will be rendered with the new Edge mode platform (ignoring X-UA-Compatible). It is our goal that Edge is the "living" document mode from here out and no further document modes will be introduced going forward.

With the changes in Microsoft Edge to no longer support document modes in most cases, Microsoft has a tool to scan your site to check and see if it has code that is not compatible with Edge.

Chrome=1 Info for IE

There is also chrome=1 that you can use or use together with one of the above options like: <meta http-equiv="X-UA-Compatible" content="IE=Edge,chrome=1">. chrome=1 is for Google's Chrome Frame which is defined as:

Google Chrome Frame is an open source browser plug-in. Users who have the plug-in installed have access to Google Chrome's open web technologies and speedy JavaScript engine when they open pages in the browser.

Google Chrome Frame seamlessly enhances your browsing experience in Internet Explorer. It displays Google Chrome Frame enabled sites using Google Chrome’s rendering technology, giving you access to the latest HTML5 features as well as Google Chrome’s performance and security features without in any way interrupting your usual browser usage.

When Google Chrome Frame is installed, the web just gets better without you having to think about it.

But for that plug-in to work you must use chrome=1 in the X-UA-Compatible meta tag.

More info on Chrome Frame can be found here.

Note: Google Chrome Frame only works for IE6 through IE9, and was retired on February 25, 2014. More info can be found here. Thanks to @mck for the link.

Validation:

HTML5:

The page will validate using the W3 Validator only when using <meta http-equiv="X-UA-Compatible" content="IE=Edge">. For other values it will throw the error: A meta element with an http-equiv attribute whose value is X-UA-Compatible must have a content attribute with the value IE=edge. In other words, if you have IE=edge,chrome=1 it will not validate. I ignore this error completely as modern browsers simply ignore this line of code.

If you must have completely valid code then consider doing this on the server level by setting HTTP header. As a note, Microsoft says, If both of these instructions are sent (meta and HTTP), the developer's preference (meta element) takes precedence over the web server setting (HTTP header). See olibre's answer or bitinn's answer for more details on how to set an HTTP header.

XHTML

There isn't an issue with validation when using <meta http-equiv="X-UA-Compatible" content="IE=Edge" /> as long as the tag is properly closed (i.e. /> vs >).

Twitter Bootstrap

This tag has been strongly recommended by the Bootstrap team since at least 2014, and Bootlint, the linter authored by the twbs team continues to throw a warning when the tag is omitted. The linter distinguishes between warnings and errors, and as such the severity of omitting this tag may be considered minor.

For more information on X-UA-Compatible see Microsoft's Website Defining Document Compatibility.

For more information on what IE supports see caniuse.com.

For more information on Twitter Bootstrap requirements, see the bootlint project wiki page.

It seems that you are using the 64-bit version of the tool to install a 32-bit/x86 architecture application. Look for the 32-bit version of the tool here:

C:\Windows\Microsoft.NET\Framework\v4.0.30319

and it should install your 32-bit application just fine.

I use MVVM, so I created some attached properties of my own, using Thomas's as a reference. It does sorting on one column at a time when you click on the header, toggling between Ascending and Descending. It sorts from the very beginning using the first column. And it shows Win7/8 style glyphs.

Normally, all you have to do is set the main property to true (but you have to explicitly declare the GridViewColumnHeaders):

<Window xmlns:local="clr-namespace:MyProjectNamespace">
  <Grid>
    <ListView local:App.EnableGridViewSort="True" ItemsSource="{Binding LVItems}">
      <ListView.View>
        <GridView>
          <GridViewColumn DisplayMemberBinding="{Binding Property1}">
            <GridViewColumnHeader Content="Prop 1" />
          </GridViewColumn>
          <GridViewColumn DisplayMemberBinding="{Binding Property2}">
            <GridViewColumnHeader Content="Prop 2" />
          </GridViewColumn>
        </GridView>
      </ListView.View>
    </ListView>
  </Grid>
<Window>

If you want to sort on a different property than the display, than you have to declare that:

<GridViewColumn DisplayMemberBinding="{Binding Property3}"
                local:App.GridViewSortPropertyName="Property4">
    <GridViewColumnHeader Content="Prop 3" />
</GridViewColumn>

Here's the code for the attached properties, I like to be lazy and put them in the provided App.xaml.cs:

I faced similar issue when the SDK tools installation was failed during the initial setup. To resolution is to download SDK tools from Android Developer Site

• Expand "USE AN EXISTING IDE" section and download standalone SDK tools
• Choose your destination as (%HOMEPATH%\android-sdks)
• Now start Android-SDKs folder and run SDK manager

Since there is so much confusion about functionality of standard service accounts, I'll try to give a quick run down.

First the actual accounts:

• LocalService account (preferred)

  A limited service account that is very similar to Network Service and meant to run standard least-privileged services. However, unlike Network Service it accesses the network as an Anonymous user.

  • Name: NT AUTHORITY\LocalService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the LocalService user account
  • has minimal privileges on the local computer
  • presents anonymous credentials on the network
  • SID: S-1-5-19
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-19)

   

• NetworkService account

  Limited service account that is meant to run standard privileged services. This account is far more limited than Local System (or even Administrator) but still has the right to access the network as the machine (see caveat above).

  • NT AUTHORITY\NetworkService
  • the account has no password (any password information you provide is ignored)
  • HKCU represents the NetworkService user account
  • has minimal privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers
  • SID: S-1-5-20
  • has its own profile under the HKEY_USERS registry key (HKEY_USERS\S-1-5-20)
  • If trying to schedule a task using it, enter NETWORK SERVICE into the Select User or Group dialog

   

• LocalSystem account (dangerous, don't use!)

  Completely trusted account, more so than the administrator account. There is nothing on a single box that this account cannot do, and it has the right to access the network as the machine (this requires Active Directory and granting the machine account permissions to something)

  • Name: .\LocalSystem (can also use LocalSystem or ComputerName\LocalSystem)
  • the account has no password (any password information you provide is ignored)
  • SID: S-1-5-18
  • does not have any profile of its own (HKCU represents the default user)
  • has extensive privileges on the local computer
  • presents the computer's credentials (e.g. MANGO$) to remote servers

   

Above when talking about accessing the network, this refers solely to SPNEGO (Negotiate), NTLM and Kerberos and not to any other authentication mechanism. For example, processing running as LocalService can still access the internet.

The general issue with running as a standard out of the box account is that if you modify any of the default permissions you're expanding the set of things everything running as that account can do. So if you grant DBO to a database, not only can your service running as Local Service or Network Service access that database but everything else running as those accounts can too. If every developer does this the computer will have a service account that has permissions to do practically anything (more specifically the superset of all of the different additional privileges granted to that account).

It is always preferable from a security perspective to run as your own service account that has precisely the permissions you need to do what your service does and nothing else. However, the cost of this approach is setting up your service account, and managing the password. It's a balancing act that each application needs to manage.

In your specific case, the issue that you are probably seeing is that the the DCOM or COM+ activation is limited to a given set of accounts. In Windows XP SP2, Windows Server 2003, and above the Activation permission was restricted significantly. You should use the Component Services MMC snapin to examine your specific COM object and see the activation permissions. If you're not accessing anything on the network as the machine account you should seriously consider using Local Service (not Local System which is basically the operating system).

In Windows Server 2003 you cannot run a scheduled task as

• NT_AUTHORITY\LocalService (aka the Local Service account), or
• NT AUTHORITY\NetworkService (aka the Network Service account).

That capability only was added with Task Scheduler 2.0, which only exists in Windows Vista/Windows Server 2008 and newer.

A service running as NetworkService presents the machine credentials on the network. This means that if your computer was called mango, it would present as the machine account MANGO$:

I use an ::after element in the cell where I want to set a minimal width regardless of the text present, like this:

.cell::after {
    content: "";
    width: 20px;
    display: block;
}

I don't have to set width on the table parent nor use table-layout.

Here is a solution that works for the asp.net button object. On the front end, add these attributes to your asp:Button definition:

<asp:Button ... OnClientClick="this.disabled=true;" UseSubmitBehavior="false" />

In the back end, in the click event handler method call, add this code to the end (preferably in a finally block)

myButton.Enabled = true;

pass a url from command line keep your url in app gradle file as follows resValue "string", "url", CommonUrl

and give a parameter in gradle.properties files as follows CommonUrl="put your url here or may be empty"

and pass a command to from command line as follows gradle assembleRelease -Pcommanurl=put your URL here

gevang's answer is great. There's another way as well to do this directly by using pcolor. Code:

[X,Y] = meshgrid(-8:.5:8);
R = sqrt(X.^2 + Y.^2) + eps;
Z = sin(R)./R;
figure;
subplot(1,3,1);
pcolor(X,Y,Z); 
subplot(1,3,2);
pcolor(X,Y,Z); shading flat;
subplot(1,3,3);
pcolor(X,Y,Z); shading interp;

Output:

Also, pcolor is flat too, as show here (pcolor is the 2d base; the 3d figure above it is generated using mesh):

To have text-align:center work you need to add that style to the #siteInfo div or wrap the input in a paragraph and add text-align:center to the paragraph.

It may be caused by IE's box model bug. To fix this, you can use the Box Model Hack.

$('.launchConfirm').on('click', function (e) {
    $('#confirm')
        .modal({ backdrop: 'static', keyboard: false })
        .one('click', '#delete', function (e) {
            //delete function
        });
});

FIDDLE

For your button:

<button class='btn btn-danger btn-xs launchConfirm' type="button" name="remove_levels"><span class="fa fa-times"></span> delete</button></td>

To connect using a username/password and specifying ports, the code looks like this:

from pyhive import presto

cursor = presto.connect(host='host.example.com',
                    port=8081,
                    username='USERNAME:PASSWORD').cursor()

sql = 'select * from table limit 10'

cursor.execute(sql)

print(cursor.fetchone())
print(cursor.fetchall())

What OS and CPU are you using? If you are using a 32-bit OS, then a process on your system physically cannot address more than 4GB of memory. Since most text editors try to load the entire file into memory, I doubt you'll find one that will do what you want. It would have to be a very fancy text editor, that can do out-of-core processing, i. e. load a chunk of the file at a time.

You may be able to load such a huge file with if you use a 64-bit text editor on a computer with a 64-bit CPU and a 64-bit operating system. And you have to make sure that you have enough space in your swap partition or your swap file.

Since :last-child is a CSS3 pseudo-class, it is not supported in IE8. I believe :first-child is supported, as it's defined in the CSS2.1 specification.

One possible solution is to simply give the last child a class name and style that class.

Another would be to use JavaScript. jQuery makes this particularly easy as it provides a :last-child pseudo-class which should work in IE8. Unfortunately, that could result in a flash of unstyled content while the DOM loads.

If using backbone.js (which contains url anchor as route), url query string may appear:

1. before url anchor:

   var url = 'http://example.com?a=1&b=3#routepath/subpath';
   

2. after url anchor:

   var url = 'http://example.com#routepath/subpath?a=1&b=3';
   

Solution:

window.location.href.replace(window.location.search, '');
// run as: 'http://example.com#routepath/subpath?a=1&b=3'.replace('?a=1&b=3', '');

It would be better to have a check before getting the string.

$newstring = substr($dynamicstring, -7);

if characters are greater then 7 return last 7 characters else return the provided string.

or do this if you need to return message or error if length is less then 7

$newstring = (strlen($dynamicstring)>7)?substr($dynamicstring, -7):"message";

You can store and read string information in a cookie.

If it is a session id coming from the server, the server can generate this cookie. And when another request is sent to the server the cookie will come too. Without having to do anything in the browser.

However if it is javascript that creates the session Id. You can create a cookie with javascript, with a function like:

function writeCookie(name,value,days) {
    var date, expires;
    if (days) {
        date = new Date();
        date.setTime(date.getTime()+(days*24*60*60*1000));
        expires = "; expires=" + date.toGMTString();
            }else{
        expires = "";
    }
    document.cookie = name + "=" + value + expires + "; path=/";
}

Then in each page you need this session Id you can read the cookie, with a function like:

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

The read function work from any page or tab of the same domain that has written it, either if the cookie was created from the page in javascript or from the server.

To store the id:

var sId = 's234543245';
writeCookie('sessionId', sId, 3);

To read the id:

var sId = readCookie('sessionId')

Consider using Roxterm instead.

roxterm --tab

opens a tab in the current window.

Here is my solution using list comprehension to search for multiple file extensions recursively in a directory and all subdirectories:

import os, glob

def _globrec(path, *exts):
""" Glob recursively a directory and all subdirectories for multiple file extensions 
    Note: Glob is case-insensitive, i. e. for '\*.jpg' you will get files ending
    with .jpg and .JPG

    Parameters
    ----------
    path : str
        A directory name
    exts : tuple
        File extensions to glob for

    Returns
    -------
    files : list
        list of files matching extensions in exts in path and subfolders

    """
    dirs = [a[0] for a in os.walk(path)]
    f_filter = [d+e for d in dirs for e in exts]    
    return [f for files in [glob.iglob(files) for files in f_filter] for f in files]

my_pictures = _globrec(r'C:\Temp', '\*.jpg','\*.bmp','\*.png','\*.gif')
for f in my_pictures:
    print f

git reset --hard

git push origin HEAD --force

If one or more of the commits is tagged, delete the tag(s) first. Otherwise the tagged commit is not removed.

end

A small patch to @Adam Sills's answer which solves FormatException on cases where the input string like "c:\u00ab\otherdirectory\" plus RegexOptions.Compiled makes the Regex compilation much faster:

    private static Regex DECODING_REGEX = new Regex(@"\\u(?<Value>[a-fA-F0-9]{4})", RegexOptions.Compiled);
    private const string PLACEHOLDER = @"#!#";
    public static string DecodeEncodedNonAsciiCharacters(this string value)
    {
        return DECODING_REGEX.Replace(
            value.Replace(@"\\", PLACEHOLDER),
            m => { 
                return ((char)int.Parse(m.Groups["Value"].Value, NumberStyles.HexNumber)).ToString(); })
            .Replace(PLACEHOLDER, @"\\");
    }

Here is a sample XAML that will allow TextBox to accept multiline text and it uses its own scrollbars:

<TextBox
Height="200"
Width="500"
TextWrapping="Wrap"
AcceptsReturn="True"
HorizontalScrollBarVisibility="Disabled"
VerticalScrollBarVisibility="Auto"/>

I had the same issue because the XML file I was uploading was encoded using UTF-8-BOM (UTF-8 byte-order mark).

Switched the encoding to UTF-8 in Notepad++ and was able to load the XML file in code.

Maybe I'm misunderstanding, but if you want truly readonly Ids why not use an actual readonly field?

public class Person
{
   public Person(int id)
   {
      m_id = id;
   }

   readonly int m_id;
   public int Id { get { return m_id; } }
}

The accepted answer here does not mention a fact that if you have a null string ToLower() will throw an exception. The safer way would be to do:

fi => (fi.DESCRIPTION ?? string.Empty).ToLower().Contains((description ?? string.Empty).ToLower())

xml4jQuery plugin gives sleep(ms,callback) method. Remaining chain would be executed after sleep period.

$(".toFill").html("Click here")
                .$on('click')
                .html('Loading...')

                .html( 'done')

2018 and later solution:

Using viewport-relative units should make your life way easier, given we have the image of a cat:

Now we want this cat inside our code, while respecting aspect ratios:

img {_x000D_
  width: 100%;_x000D_
  height: auto;_x000D_
}

<img src="https://www.petmd.com/sites/default/files/petmd-cat-happy-10.jpg" alt="cat">

So far not really interesting, but what if we would like to change the cats width to be the maximum of 50% of the viewport?

img {_x000D_
  width: 100%;_x000D_
  height: auto;_x000D_
  /* Magic! */_x000D_
  max-width: 50vw;_x000D_
}

<img src="https://www.petmd.com/sites/default/files/petmd-cat-happy-10.jpg" alt="cat">

The same image, but now restricted to a maximum width of 50vw vw (=viewport width) means the image will be X width of the viewport, depending on the digit provided. This also works for height:

img {_x000D_
  width: auto;_x000D_
  height: 100%;_x000D_

I hope to provide more background knowledge here.

First, constructor signature of the of method threading::Thread:

class threading.Thread(group=None, target=None, name=None, args=(), kwargs={}, *, daemon=None)

args is the argument tuple for the target invocation. Defaults to ().

Second, A quirk in Python about tuple:

Empty tuples are constructed by an empty pair of parentheses; a tuple with one item is constructed by following a value with a comma (it is not sufficient to enclose a single value in parentheses).

On the other hand, a string is a sequence of characters, like 'abc'[1] == 'b'. So if send a string to args, even in parentheses (still a sting), each character will be treated as a single parameter.

However, Python is so integrated and is not like JavaScript where extra arguments can be tolerated. Instead, it throws an TypeError to complain.

I had fix this with adduser *username* dialout. I never had this error again, even though previously the only way to get it to work was to reboot the PC or unplug and replug the usb to serial adapter.

For compititve programming

1) For input the value in an 2D-Array

row=input()
main_list=[]
for i in range(0,row):
    temp_list=map(int,raw_input().split(" "))
    main_list.append(temp_list)

2) For displaying 2D Array

for i in range(0,row):
    for j in range(0,len(main_list[0]):
        print main_list[i][j],
        print

Try this:

Use back-ticks for NAME

CREATE TABLE `teachers` (
  `id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `name` varchar(50) NOT NULL,
  `addr` varchar(255) NOT NULL,
  `phone` int(10) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8

Nope, you can't click ‘through’ an element. You can get the co-ordinates of the click and try to work out what element was underneath the clicked element, but this is really tedious for browsers that don't have document.elementFromPoint. Then you still have to emulate the default action of clicking, which isn't necessarily trivial depending on what elements you have under there.

Since you've got a fully-transparent window area, you'll probably be better off implementing it as separate border elements around the outside, leaving the centre area free of obstruction so you can really just click straight through.

This answer outlines two ways to workaround APIs that don't support CORS:

• Use a CORS Proxy
• Use JSONP if the API Supports it

One workaround is to use a CORS PROXY:

angular.module("app",[])
.run(function($rootScope,$http) { 
     var proxy = "//cors-anywhere.herokuapp.com";
     var url = "http://api.ipify.org/?format=json";
     $http.get(proxy +'/'+ url)
       .then(function(response) {
         $rootScope.response = response.data;
     }).catch(function(response) {
         $rootScope.response = 'ERROR: ' + response.status;
     })     
})

<script src="//unpkg.com/angular/angular.js"></script>
<body ng-app="app">
   Response = {{response}}
</body>

For more information, see

• GitHub: CORS Anywhere

Use JSONP if the API supports it:

 var url = "//api.ipify.org/";
 var trust = $sce.trustAsResourceUrl(url);
 $http.jsonp(trust,{params: {format:'jsonp'}})
   .then(function(response) {
     console.log(response);
     $scope.response = response.data;
 }).catch(function(response) {
     console.log(response);
     $scope.response = 'ERROR: ' + response.status;
 })

Sharing my methods in case someone needs them:

 /** Determines if the context calling has the required permission
 * @param context - the IPC context
 * @param permissions - The permissions to check
 * @return true if the IPC has the granted permission
 */
public static boolean hasPermission(Context context, String permission) {

    int res = context.checkCallingOrSelfPermission(permission);

    Log.v(TAG, "permission: " + permission + " = \t\t" + 
    (res == PackageManager.PERMISSION_GRANTED ? "GRANTED" : "DENIED"));

    return res == PackageManager.PERMISSION_GRANTED;

}

/** Determines if the context calling has the required permissions
 * @param context - the IPC context
 * @param permissions - The permissions to check
 * @return true if the IPC has the granted permission
 */
public static boolean hasPermissions(Context context, String... permissions) {

    boolean hasAllPermissions = true;

    for(String permission : permissions) {
        //you can return false instead of assigning, but by assigning you can log all permission values
        if (! hasPermission(context, permission)) {hasAllPermissions = false; }
    }

    return hasAllPermissions;

}

And to call it:

boolean hasAndroidPermissions = SystemUtils.hasPermissions(mContext, new String[] {
                android.Manifest.permission.ACCESS_WIFI_STATE,
                android.Manifest.permission.READ_PHONE_STATE,
                android.Manifest.permission.ACCESS_NETWORK_STATE,
                android.Manifest.permission.INTERNET,

I don't see next option in a list of answers, but I can get interactive prompt with "-i" key:

This works for me:

#! /bin/bash

CACERTS=$(readlink -e $(dirname $(readlink -e $(which keytool)))/../lib/security/cacerts)

if keytool -list -keystore $CACERTS -storepass changeit > /dev/null ; then
    echo $CACERTS
else
    echo 'Can not find cacerts file.' >&2
    exit 1
fi

Only for Linux. My Solaris has no readlink. In the end I used this Perl-Script:

#! /usr/bin/env perl
use strict;
use warnings;
use Cwd qw(realpath);
$_ = realpath((grep {-x && -f} map {"$_/keytool"} split(':', $ENV{PATH}))[0]);
die "Can not find keytool" unless defined $_;
my $keytool = $_;
print "Using '$keytool'.\n";
s/keytool$//;
$_ = realpath($_ . '../lib/security/cacerts');
die "Can not find cacerts" unless -f $_;
my $cacerts = $_;
print "Importing into '$cacerts'.\n";
`$keytool -list -keystore "$cacerts" -storepass changeit`;
die "Can not read key container" unless $? == 0;
exit if $ARGV[0] eq '-d';
foreach (@ARGV) {
    my $cert = $_;
    s/\.[^.]+$//;
    my $alias = $_;
    print "Importing '$cert' as '$alias'.\n";
    `keytool -importcert -file "$cert" -alias "$alias" -keystore "$cacerts" -storepass changeit`;
    warn "Can not import certificate: $?" unless $? == 0;
}

Open the pom.xml file.

under the project tag add <dependencies> as another tag, and google for the Maven dependencies. I used this to search.

So after getting the dependency create another tag dependency inside <dependencies> tag.

So ultimately it will look something like this.

Comment to Skelly's really helpful workaround: in Bootstrap-sass 3.3.6, utilities.scss, line 19: .pull-left has float:left !important. Since that, I recommend to use !important in his CSS as well:

.dropdown-submenu.pull-left {
    float:none !important;
}

X, Y , Z are your desired values

textField.layer.sublayerTransform = CATransform3DMakeTranslation(x, y, z)

This should give the location of the files that contain your pattern:

Get-ChildItem -Recurse | Select-String "dummy" -List | Select Path

Also you can use dirname(__DIR__, $level) for access any folding level without traversing

If you have latest compiler, you can change the following in your build settings:

 C++ Language Dialect    C++14[-std=c++14]

This works for me.

Create an instance of OrientationEventListener class and enable it.

OrientationEventListener mOrientationEventListener = new OrientationEventListener(YourActivity.this) {
    @Override
    public void onOrientationChanged(int orientation) {
        Log.d(TAG,"orientation = " + orientation);
    }
};

if (mOrientationEventListener.canDetectOrientation())
    mOrientationEventListener.enable();

Pass it a Comparator. Fill in your desired type in place of T

Using lambdas (Java 8+):

int initialCapacity = 10;
PriorityQueue<T> pq = new PriorityQueue<>(initialCapacity, (e1, e2) -> { return e1.compareTo(e2); });

Classic way, using anonymous class:

int initialCapacity = 10;
PriorityQueue<T> pq = new PriorityQueue<>(initialCapacity, new Comparator<T> () {

    @Override
    public int compare(T e1, T e2) {
        return e1.compareTo(e2);
    }

});

To sort in reverse order, simply swap e1, e2.

Per Phairoh: Use this in the Page/Component just in case the panel name changes

<script type="text/javascript">

         function JSFunction() {

Here, Role is an enum which contains the following values [ADMIN, USER, OTHER].

List<Role> roleList = Arrays.asList(Role.values());
roleList.forEach(role -> {
    System.out.println(role);
    });

If you want to kill -9 based on a string (you might want to try kill first) you can do something like this:

ps axf | grep <process name> | grep -v grep | awk '{print "kill -9 " $1}'

This will show you what you're about to kill (very, very important) and just pipe it to sh when the time comes to execute:

ps axf | grep <process name> | grep -v grep | awk '{print "kill -9 " $1}' | sh

To get the HTML file input form element to only accept PDFs, you can use the accept attribute in modern browsers such as Firefox 9+, Chrome 16+, Opera 11+ and IE10+ like such:

<input name="file1" type="file" accept="application/pdf">

You can string together multiple mime types with a comma.

The following string will accept JPG, PNG, GIF, PDF, and EPS files:

<input name="foo" type="file" accept="image/jpeg,image/gif,image/png,application/pdf,image/x-eps">

In older browsers the native OS file dialog cannot be restricted – you'd have to use Flash or a Java applet or something like that to handle the file transfer.

And of course it goes without saying that this doesn't do anything to verify the validity of the file type. You'll do that on the server-side once the file has uploaded.

A little update – with javascript and the FileReader API you could do more validation client-side before uploading huge files to your server and checking them again.

 scope: false
 transclude: false

and you will have the same scope(with parent element)

$scope.$watch(...

There are a lot of ways how to access parent scope depending on this two options scope& transclude.

You can use bellow code to get route name in blade file

Use Below code:

private void getCallDeatils() {
    StringBuffer stringBuffer = new StringBuffer();
    Cursor managedCursor = getActivity().managedQuery(CallLog.Calls.CONTENT_URI, null, null, null, null);
    int number = managedCursor.getColumnIndex(CallLog.Calls.NUMBER);
    int type = managedCursor.getColumnIndex(CallLog.Calls.TYPE);
    int date = managedCursor.getColumnIndex(CallLog.Calls.DATE);

    int duration = managedCursor.getColumnIndex(CallLog.Calls.DURATION);
    stringBuffer.append("Call Deatils");
    while (managedCursor.moveToNext()) {
        String phNumber = managedCursor.getString(number);
        String callType = managedCursor.getString(type);
        String callDate = managedCursor.getString(date);
        Date callDayTime = new Date(Long.valueOf(callDate));
        DateFormat df = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss");
        String reportDate = df.format(callDayTime);
        String callDuration = managedCursor.getString(duration);
        String dir = null;
        int dircode = Integer.parseInt(callType);
        switch (dircode) {
            case CallLog.Calls.OUTGOING_TYPE:
                dir = "OUTGOING";
                break;

            case CallLog.Calls.INCOMING_TYPE:
                dir = "INCOMING";

                break;

            case CallLog.Calls.MISSED_TYPE:
                dir = "MISSED";
                break;

        }
        stringBuffer.append("\nPhone Number:--- " + phNumber + " \nCall Type:--- " + dir + " \nCall Date:--- " +callDate + " \nCall duration in sec :--- " + callDuration);
        stringBuffer.append("\n----------------------------------");

        logs.add(new LogClass(phNumber,dir,reportDate,callDuration));

I had the same problem but none of the answers above worked. The solution for me was to restore the Manager web application that is bundled with Tomcat.

Obviously you mean the baseurl. If so:

base url: URL to your CodeIgniter root. Typically this will be your base URL, | WITH a trailing slash.

Root in codeigniter specifically means that the position where you can append your controller to your url.

For example, if the root is localhost/ci_installation/index.php/, then to access the mycont controller you should go to localhost/ci_installation/index.php/mycont.

So, instead of writing such a long link you can (after loading "url" helper) , replace the term localhost/ci_installation/index.php/ by base_url() and this function will return the same string url.

NOTE: if you hadn't appended index.php/ to your base_url in your config.php, then if you use base_url(), it will return something like that localhost/ci_installation/mycont. And that will not work, because you have to access your controllers from index.php, instead of that you can place a .htaccess file to your codeigniter installation position. Cope that the below code to it:

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /imguplod/index.php/$1 [L]

And it should work :)

I know the question is for JUnit4, but if you happen to be stuck at JUnit3, you could create a short utility function like that:

private void assertArrayEquals(Object[] esperado, Object[] real) {
    assertEquals(Arrays.asList(esperado), Arrays.asList(real));     
}

In JUnit3, this is better than directly comparing the arrays, since it will detail exactly which elements are different.

<!doctype html>
<html>
<body>
<p id = "myString">zyxtspqnmdba</p>
<p id = "orderedString"></p>
<script>
var myString = document.getElementById("myString").innerHTML;
orderString(myString);
function orderString(str) {
    var i = 0;
    var myArray = str.split("");
    while (i < str.length){
        var j = i + 1;
        while (j < str.length) {
            if (myArray[j] < myArray[i]){
                var temp = myArray[i];
                myArray[i] = myArray[j];
                myArray[j] = temp;
            }
            j++;
        }
        i++;
    }
    var newString = myArray.join("");
    document.getElementById("orderedString").innerHTML = newString;
}
</script>
</body>
</html>

I faced a similar issue. I checked for the below:

1. if ssh is not installed on your machine, you will have to install it firstly. (You will get a message saying ssh is not recognized as a command).
2. Port 22 is open or not on the server you are trying to ssh.
3. If the control of remote server is in your hands and you have permissions, try to disable firewall on it.
4. Try to ssh again.

If port is not an issue then you would have to check for firewall settings as it is the one that is blocking your connection.

For me too it was a firewall issue between my machine and remote server.I disabled the firewall on the remote server and I was able to make a connection using ssh.

var datestr = '2012.08.10';
var timestamp = (new Date(datestr.split(".").join("-")).getTime())/1000;

This is an old question, and there are many answers, most of which will be more or less helpful; however, there is one, very important and still relevant point, which none of the answers touch (providing, instead, different hacks to make build possible), and which, I think, in no way has a less importance.. on the contrary.

According to your log message, you are using Maven, which is a Project Management tool, firmly following the conventions, over configuration principle.

When Maven builds the project:

1. it expects your project to have a particular directory structure, so that it knows where to expect what. This is called a Maven's Standard Directory Layout;
2. during the build, it creates also proper directory structure and places files into corresponding locations/directories, and this, in compliance with the Sun Microsystems Directory Structure Standard for Java EE [web] applications.

You may incorporate many things, including maven plugins, changing/reconfiguring project root directory, etc., but better and easier is to follow the default conventions over configuration, according to which, (now is the answer to your problem) there is one simple step that can make your project work: Just place your web.xml under src\main\webapp\WEB-INF\ and try to build the project with mvn package.

You can use try catch block here:

s="1234"
try:
    num=int(s)
    print "S contains only digits"
except:
    print "S doesn't contain digits ONLY"

I wrote a c++ program based on Win32 to write an assembly to the boot sector of a pen-drive. When the computer is booted from the pen-drive it executes the code successfully - have a look here C++ Program to write to the boot sector of a USB Pendrive

This program is a few lines that should be compiled on a compiler with windows compilation configured - such as a visual studio compiler - any available version.

=== #---case equality

== #--- generic equality

both works similar but "===" even do case statements

"test" == "test"  #=> true
"test" === "test" #=> true

here the difference

String === "test"   #=> true
String == "test"  #=> false

Another example method, to mix the prompt using print, if you need to make your code simpler.

Format:-

x = raw_input () -- This will return the user input as a string

x= int(raw_input()) -- Gets the input number as a string from raw_input() and then converts it to an integer using int().

print '\nWhat\'s your name ?', 
name = raw_input('--> ')
print '\nHow old are you, %s?' % name,
age = int(raw_input())
print '\nHow tall are you (in cms), %s?' % name,
height = int(raw_input())
print '\nHow much do you weigh (in kgs), %s?' % name,
weight = int(raw_input())

print '\nSo, %s is %d years old, %d cms tall and weighs %d kgs.\n' %(
name, age, height, weight)

Strings are nullable in C# anyway because they are reference types. You can just use public string CMName { get; set; } and you'll be able to set it to null.

Look here:

http://tratt.net/laurie/tech_articles/articles/tail_call_optimization

As you probably know, recursive function calls can wreak havoc on a stack; it is easy to quickly run out of stack space. Tail call optimization is way by which you can create a recursive style algorithm that uses constant stack space, therefore it does not grow and grow and you get stack errors.

Jan 2020 Update

@Flimm has explained all the differences very well. Generally, we want to know the difference between all tools because we want to decide what's best for us. So, the next question would be: which one to use? I suggest you choose one of the two official ways to manage virtual environments:

• Python Packaging now recommends Pipenv
• Python.org now recommends venv

Re: textFile.getch(), did you make that up, or do you have a reference that says it should work? If it's the latter, get rid of it. If it's the former, don't do that. Get a good reference.

textFile >> ch;

May be i did not fully understand the problem, but, centering all view inside a ConstraintLayout seems very simple. This is what I used:

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center">

Last two lines did the trick!

As Matt said (https://stackoverflow.com/a/43323045/2767413) you should install the build-tools for windows. However, I did it via cmd and got an error, although I am the administrator -

Please restart this script from an administrative PowerShell!
The build tools cannot be installed without administrative rights.
To fix, right-click on PowerShell and run "as Administrator".

I got the same error via a PowerShell.

jQuery.fn is defined shorthand for jQuery.prototype. From the source code:

jQuery.fn = jQuery.prototype = {

That means jQuery.fn.jquery is an alias for jQuery.prototype.jquery, which returns the current jQuery version. Again from the source code:

// The current version of jQuery being used

Input Dimension Clarified:

Not a direct answer, but I just realized the word Input Dimension could be confusing enough, so be wary:

It (the word dimension alone) can refer to:

a) The dimension of Input Data (or stream) such as # N of sensor axes to beam the time series signal, or RGB color channel (3): suggested word=> "InputStream Dimension"

b) The total number /length of Input Features (or Input layer) (28 x 28 = 784 for the MINST color image) or 3000 in the FFT transformed Spectrum Values, or

"Input Layer / Input Feature Dimension"

c) The dimensionality (# of dimension) of the input (typically 3D as expected in Keras LSTM) or (#RowofSamples, #of Senors, #of Values..) 3 is the answer.

"N Dimensionality of Input"

d) The SPECIFIC Input Shape (eg. (30,50,50,3) in this unwrapped input image data, or (30, 250, 3) if unwrapped Keras:

Keras has its input_dim refers to the Dimension of Input Layer / Number of Input Feature

model = Sequential()
model.add(Dense(32, input_dim=784))  #or 3 in the current posted example above
model.add(Activation('relu'))

In Keras LSTM, it refers to the total Time Steps

The term has been very confusing, is correct and we live in a very confusing world!!

I find one of the challenge in Machine Learning is to deal with different languages or dialects and terminologies (like if you have 5-8 highly different versions of English, then you need to very high proficiency to converse with different speakers). Probably this is the same in programming languages too.

You can just use a simple loop: -

>>> mylist = ['10', '12', '14']
>>> for elem in mylist:
        print elem 

10
12
14

This small research proves and refines the answer by Magnus

The most platform-independent syntax is

(empty line)
[comment]: # (This actually is the most platform independent comment)

Both conditions are important:

1. Using # (and not <>)
2. With an empty line before the comment. Empty line after the comment has no impact on the result.

The strict Markdown specification CommonMark only works as intended with this syntax (and not with <> and/or an empty line)

To prove this we shall use the Babelmark2, written by John MacFarlane. This tool checks the rendering of particular source code in 28 Markdown implementations.

(+ — passed the test, - — didn't pass, ? — leaves some garbage which is not shown in rendered HTML).

• No empty lines, using <> 13+, 15-
• Empty line before the comment, using <> 20+, 8-
• Empty lines around the comment, using <> 20+, 8-
• No empty lines, using # 13+ 1? 14-
• Empty line before the comment, using # 23+ 1? 4-
• Empty lines around the comment, using # 23+ 1? 4-
• HTML comment with 3 hyphens 1+ 2? 25- from the chl's answer (note that this is different syntax)

This proves the statements above.

These implementations fail all 7 tests. There's no chance to use excluded-on-render comments with them.

An alternative way to get a list of column names not mentioned here is to select from a pragma function:

SELECT name FROM PRAGMA_TABLE_INFO('your_table');
name      
tbl_name  
rootpage  
sql

You can check if a certain column exists by running:

SELECT 1 FROM PRAGMA_TABLE_INFO('your_table') WHERE name='sql';
1

This is what you use if you don't want to parse the result of select sql from sqlite_master or pragma table_info.

Reference:

https://www.sqlite.org/pragma.html#pragfunc

It can't parse that string because "UTC" is not a valid time zone designator.

UTC time is denoted by adding a 'Z' to the end of the time string, so your parsing code should look like this:

DateTime.Parse("Tue, 1 Jan 2008 00:00:00Z");

From the Wikipedia article on ISO 8601

If the time is in UTC, add a 'Z' directly after the time without a space. 'Z' is the zone designator for the zero UTC offset. "09:30 UTC" is therefore represented as "09:30Z" or "0930Z". "14:45:15 UTC" would be "14:45:15Z" or "144515Z".

UTC time is also known as 'Zulu' time, since 'Zulu' is the NATO phonetic alphabet word for 'Z'.

if you try with lubridate:

lubridate::week(ymd("2014-03-16", "2014-03-17","2014-03-18", '2014-01-01'))

[1] 11 11 12  1

The pattern is the same. Try isoweek

lubridate::isoweek(ymd("2014-03-16", "2014-03-17","2014-03-18", '2014-01-01'))
[1] 11 12 12  1

As for me, chaining set methods is the cleanest way

const params = new HttpParams()
.set('aaa', '111')
.set('bbb', "222");

in menu bar click on Edit->preference->advance at bottom click the check box true that is for Show develop menu in menu bar now a develop menu is display at menu bar where you can see all develop option and inspect.

You simply need to make cab a string:

cab = '6176'

As the error message states, you cannot do <int> in <string>:

>>> 1 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not int
>>> 

because integers and strings are two totally different things and Python does not embrace implicit type conversion ("Explicit is better than implicit.").

In fact, Python only allows you to use the in operator with a right operand of type string if the left operand is also of type string:

>>> '1' in '123'  # Works!
True
>>>
>>> [] in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not list
>>>
>>> 1.0 in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not float
>>>
>>> {} in '123'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'in <string>' requires string as left operand, not dict
>>>

2019 update

As pointed out by others in related questions (see here, here, here, here, here, here, and here), you can now unstage a file with git restore --staged <file>.

To unstage all the files in your project, run the following from the root of the repository (the command is recursive):

git restore --staged .

If you only want to unstage the files in a directory, navigate to it before running the above or run:

git restore --staged <directory-path>

Notes

• git restore was introduced in July 2019 and released in version 2.23.
  With the --staged flag, it restores the content of the working tree from HEAD (so it does the opposite of git add and does not delete any change).

• This is a new command, but the behaviour of the old commands remains unchanged. So the older answers with git reset or git reset HEAD are still perfectly valid.

• When running git status with staged uncommitted file(s), this is now what Git suggests to use to unstage file(s) (instead of git reset HEAD <file> as it used to prior to v2.23).

I use this simple way

docker exec -it <container id or name> hostname -i

e.g

ubuntu@myhost:~$ docker exec -it 3d618ac670fe hostname -i
10.0.1.5

It seems to me that you are not very familiar with interfaces. In the code you have posted, you don't need to implement AutoCloseable.

You only have to (or should) implement Closeable or AutoCloseable if you are about to implement your own PrintWriter, which handles files or any other resources which needs to be closed.

In your implementation, it is enough to call pw.close(). You should do this in a finally block:

PrintWriter pw = null;
try {
   File file = new File("C:\\test.txt");
   pw = new PrintWriter(file);
} catch (IOException e) {
   System.out.println("bad things happen");
} finally {
   if (pw != null) {
      try {
         pw.close();
      } catch (IOException e) {
      }
   }
}

The code above is Java 6 related. In Java 7 this can be done more elegantly (see this answer).

if(arrayName.length > index && arrayName[index] !== null) {
    //arrayName[index] has a value
}

Here's how I do it Angular 8:

Get a local reference of your form:

<form name="myForm" #myForm="ngForm"></form>

@ViewChild('myForm', {static: false}) myForm: NgForm;

And whenever you need to reset the form, call resetForm method:

this.myForm.resetForm();

You will need FormsModule from @angular/forms for it to work. Be sure to add it to your module imports.

Use the SelectMany extension method

list = listOfList.SelectMany(x => x).ToList();

Inside <appSettings> you can create application keys,

<add key="KeyName" value="Keyvalue"/>

Later on you can access these values using:

ConfigurationManager.AppSettings["Keyname"]

Use the below query:

 SELECT * FROM document INTO OUTFILE 'c:/order-1.csv' FIELDS TERMINATED BY ','  
 ENCLOSED BY '"' LINES TERMINATED BY '\n';

use :

char ch=**scanner.nextChar**()

Or you can see below

There are number of PHP libraries on the web to convert HTML page to PDF file. They are easy to implement and deploy when you are working on any web application in core PHP. But when we try to integrate this libraries with any framework or template, then it becomes very tedious work if the framework which we are using does not have its own library to integrate it with any PDF library. The same situation came in front of me when there was one requirement to convert HTML page to PDF file and the framework I was using was codeigniter.

I searched on web and got number of PHP libraries to convert HTML page to PDF file. After lot of research and googling I decided to go with TCPDF PHP library to convert HTML page to PDF file for my requirement. I found TCPDf PHP library quite easy to integrate with codeigniter and stated working on it. After successfully completing my integration of codeigniter and TCPDF, I thought of sharing this script on web.

Now, let’s start with implimentation of the code.

Download the TCPDF library code, you can download it from TCPDF website http://www.tcpdf.org/.

Now create “tcpdf” folder in “application/helpers/” directory of your web application which is developed in codeigniter. Copy all TCPDF library files and paste it in “application/helpers/tcpdf/” directory. Update the configuration file “tcpdf_config.php” of TCPDF, which is located in “application/helpers/tcpdf/config” directory, do changes according to your applicatoin requirements. We can set logo, font, font size, with, height, header etc in the cofing file. Give read, write permissions to “cache” folder which is there in tcpdf folder. After defining your directory structure, updating configuration file and assigning permissions, here starts your actual coding part.

Create one PHP helper file in “application/helpers/” directory of codeigniter, say “pdf_helper.php”, then copy below given code and paste it in helper file

Helper: application/helpers/pdf_helper.php

function tcpdf()
{
    require_once('tcpdf/config/lang/eng.php');
    require_once('tcpdf/tcpdf.php');
}

Then in controller file call the above helper, suppose our controller file is “createpdf.php” and it has method as pdf(), so the method pdf() will load the “pdf_helper” helper and will also have any other code.

Controller: application/controllers/createpdf.php

function pdf()
{
    $this->load->helper('pdf_helper');
    /*
        ---- ---- ---- ----
        your code here
        ---- ---- ---- ----
    */
    $this->load->view('pdfreport', $data);
}

Now create one view file, say “pdfreport.php” in “application/views/” directory, which is also loaded in pdf() method in controller. So in view file we can directly call the tcpdf() function which we have defined in “pdf_helper” helper, which will load all required TCPDF classes, functions, variable etc. Then we can directly use the TCPDF example codes as it is in our current controller or view. Now in out current view “pdfreport” copy the given code below:

View: application/views/pdfreport.php

tcpdf();
$obj_pdf = new TCPDF('P', PDF_UNIT, PDF_PAGE_FORMAT, true, 'UTF-8', false);
$obj_pdf->SetCreator(PDF_CREATOR);
$title = "PDF Report";
$obj_pdf->SetTitle($title);
$obj_pdf->SetHeaderData(PDF_HEADER_LOGO, PDF_HEADER_LOGO_WIDTH, $title, PDF_HEADER_STRING);
$obj_pdf->setHeaderFont(Array(PDF_FONT_NAME_MAIN, '', PDF_FONT_SIZE_MAIN));
$obj_pdf->setFooterFont(Array(PDF_FONT_NAME_DATA, '', PDF_FONT_SIZE_DATA));
$obj_pdf->SetDefaultMonospacedFont('helvetica');
$obj_pdf->SetHeaderMargin(PDF_MARGIN_HEADER);
$obj_pdf->SetFooterMargin(PDF_MARGIN_FOOTER);
$obj_pdf->SetMargins(PDF_MARGIN_LEFT, PDF_MARGIN_TOP, PDF_MARGIN_RIGHT);
$obj_pdf->SetAutoPageBreak(TRUE, PDF_MARGIN_BOTTOM);
$obj_pdf->SetFont('helvetica', '', 9);
$obj_pdf->setFontSubsetting(false);
$obj_pdf->AddPage();
ob_start();
    // we can have any view part here like HTML, PHP etc
    $content = ob_get_contents();
ob_end_clean();
$obj_pdf->writeHTML($content, true, false, true, false, '');
$obj_pdf->Output('output.pdf', 'I');

Thus our HTML page will be converted to PDF using TCPDF in CodeIgniter. We can also embed images,css,modifications in PDF file by using TCPDF library.

The first parameter to the iterator in forEach is the value and second is the key of the object.

angular.forEach(objectToIterate, function(value, key) {
    /* do something for all key: value pairs */
});

In your example, the outer forEach is actually:

angular.forEach($scope.filters, function(filterObj , filterKey)

Please note that you can use view.setZ(float) starting from API level 21. Here you can find more info.

But I need the match result to be ... not in a match group...

For what you are trying to do, this should work. \K resets the starting point of the match.

\bObject Name:\s+\K\S+

You can do the same for getting your Security ID matches.

\bSecurity ID:\s+\K\S+

You can apply the style via javascript. This is the Js code below that applies the filter to the image with the ID theImage.

function invert(){
document.getElementById("theImage").style.filter="invert(100%)";
}

And this is the

<img id="theImage" class="img-responsive" src="http://i.imgur.com/1H91A5Y.png"></img>

Now all you need to do is call invert() We do this when the image is clicked.

function invert(){_x000D_
document.getElementById("theImage").style.filter="invert(100%)";_x000D_
}

<h4> Click image to invert </h4>_x000D_
_x000D_
<img id="theImage" class="img-responsive" src="http://i.imgur.com/1H91A5Y.png" onClick="invert()" ></img>

We use this on our website

You can not access the docker's IP from outside of that host machine. If your browser is on another machine better to map the host port to container port by passing -p 8080:8080 to run command.

Passing -p you can map host port to container port and a proxy is set to forward all traffix for said host port to designated container port.

I ran into the exact same issue. After compiling without the -fexceptions build flag, the file compiled with no issue

The issue appears with parsing the JSON from request body, tipical for an invalid JSON. If you're using curl on windows, try escaping the json like -d "{"name":"value"}" or even -d "{"""name""":"value"""}"

On the other hand you can ommit the content-type header in which case whetewer is sent will be converted to your String argument

The command looks quite fine. Could you try to run -v (verbose mode) and then we can figure out what it is wrong on the authentication?

Also as mention in the other answer, maybe could be this issue - that you need to convert the keys (answered already here): How to convert SSH keypairs generated using PuttyGen(Windows) into key-pairs used by ssh-agent and KeyChain(Linux) OR http://winscp.net/eng/docs/ui_puttygen (depending what you need)

You need to only depend on one major version of angular, so update all modules depending on angular 2.x :

• update @angular/flex-layout to ^2.0.0-beta.9
• update @angular/material to ^2.0.0-beta.12
• update angularfire2 to ^4.0.0-rc.2
• update zone.js to ^0.8.18
• update webpack to ^3.8.1
• add @angular/[email protected] (required for @angular/material)
• replace angular2-google-maps by @agm/[email protected] (new name)

My recommendation is to solve problems that you're interested in, writing code that might be useful to you.

Java is a huge box. It's got a lot of computer science inside: graphics, scientific computing, relational databases, user interfaces for desktop and web, messaging and queuing, multi-threading, security, and more. Each area has their own "beginner problem". Which one do you mean?

How do you define "beginner problem"? Maybe you're having trouble because you aren't narrowing your search enough.

If your imagination is lacking, your best bet is to Google something like "java beginner practice problems" and investigate what you get back.

Or start with Sun's on-line Java tutorial and work you way all the way through it. You'll know a fair amount about Java when you're done.
