For a project this size, you should stop writing pure JavaScript and turn to some of the libraries available. I'd recommend jQuery (http://jquery.com/), which allows you to select elements by css-selectors, which I recon should speed up your development quite a bit.

Example of your code then becomes;

function AddtoCart() {
  var len = $("#Items tr").length, $row, $inp1, $inp2, $cells;

  $row = $("#Items td:first").clone(true);
  $cells = $row.find("td");

  $cells.get(0).html( len );

  $inp1 = $cells.get(1).find("input:first");
  $inp1.attr("id", $inp1.attr("id") + len).val("");

  $inp2 = $cells.get(2).find("input:first");
  $inp2.attr("id", $inp2.attr("id") + len).val("");

  $("#Items").append($row);
    }

I can see that you might not understand that code yet, but take a look at jQuery, it's easy to learn and will make this development way faster.

I would use the libraries already created specifically for js shopping carts if I were you though.

To your problem; If i look at your jsFiddle, it doesn't even seem like you have defined a table with the id Items? Maybe that's why it doesn't work?

hours (h) calculated by floor division (by //) of seconds by 3600 (60 min/hr * 60 sec/min)

minutes (m) calculated by floor division of remaining seconds (remainder from hour calculation, by %) by 60 (60 sec/min)

similarly, seconds (s) by remainder of hour and minutes calculation.

Rest is just string formatting!

def hms(seconds):
    h = seconds // 3600
    m = seconds % 3600 // 60
    s = seconds % 3600 % 60
    return '{:02d}:{:02d}:{:02d}'.format(h, m, s)

print(hms(7500))  # Should print 02h05m00s

This solution uses an Asynchronous call. It will likely work better than a synchronous solution.

var request = new XMLHttpRequest();
request.open("GET", "../../data/file.json", false);
request.send(null);
request.onreadystatechange = function() {
  if ( request.readyState === 4 && request.status === 200 ) {
    var my_JSON_object = JSON.parse(request.responseText);
    console.log(my_JSON_object);
  }
}

As the most popular answer suggests, basically its because your PYTHONPATH or sys.path includes . but not your path to your package. And the relative import is relative to your current working directory, not the file where the import happens; oddly.

You could fix this by first changing your relative import to absolute and then either starting it with:

PYTHONPATH=/path/to/package python -m test_A.test

OR forcing the python path when called this way, because:

With python -m test_A.test you're executing test_A/test.py with __name__ == '__main__' and __file__ == '/absolute/path/to/test_A/test.py'

That means that in test.py you could use your absolute import semi-protected in the main case condition and also do some one-time Python path manipulation:

from os import path
…
def main():
…
if __name__ == '__main__':
    import sys
    sys.path.append(path.join(path.dirname(__file__), '..'))
    from A import foo

    exit(main())

Your function has a couple of smallint parameters.
But in the call, you are using numeric literals that are presumed to be type integer.

A string literal or string constant ('123') is not typed immediately. It remains type "unknown" until assigned or cast explicitly.

However, a numeric literal or numeric constant is typed immediately. Per documentation:

A numeric constant that contains neither a decimal point nor an exponent is initially presumed to be type integer if its value fits in type integer (32 bits); otherwise it is presumed to be type bigint if its value fits in type bigint (64 bits); otherwise it is taken to be type numeric. Constants that contain decimal points and/or exponents are always initially presumed to be type numeric.

More explanation and links in this related answer:

• PostgreSQL ERROR: function to_tsvector(character varying, unknown) does not exist

Solution

Add explicit casts for the smallint parameters or quote them.

Demo

CREATE OR REPLACE FUNCTION f_typetest(smallint)
  RETURNS bool AS 'SELECT TRUE' LANGUAGE sql;

Incorrect call:

SELECT * FROM f_typetest(1);

Correct calls:

SELECT * FROM f_typetest('1');
SELECT * FROM f_typetest(smallint '1');
SELECT * FROM f_typetest(1::int2);
SELECT * FROM f_typetest('1'::int2);

For Windows:

You may find the need to check the status of your domains DNS records, or check the Name Servers to see which records the servers are pulling.

1. Launch Windows Command Prompt by navigating to Start > Command Prompt or via Run > CMD.

2. Type NSLOOKUP and hit Enter. The default Server is set to your local DNS, the Address will be your local IP.

3. Set the DNS Record type you wish to lookup by typing set type=## where ## is the record type, then hit Enter. You may use ANY, A, AAAA, A+AAAA, CNAME, MX, NS, PTR, SOA, or SRV as the record type.

4. Now enter the domain name you wish to query then hit Enter.. In this example, we will use Managed.com.

5. NSLOOKUP will now return the record entries for the domain you entered.

6. You can also change the Name Servers which you are querying. This is useful if you are checking the records before DNS has fully propagated. To change the Name Server type server [name server]. Replace [name server] with the Name Servers you wish to use. In this example, we will set these as NSA.managed.com.

7. Once changed, change the query type (Step 3) if needed then enter new a new domain (Step 4.)

For Linux:

1) Check DNS Records Using Dig Command Dig stands for domain information groper is a flexible tool for interrogating DNS name servers. It performs DNS lookups and displays the answers that are returned from the name server(s) that were queried. Most DNS administrators use dig to troubleshoot DNS problems because of its flexibility, ease of use and clarity of output. Other lookup tools tend to have less functionality than dig.

2) Check DNS Records Using NSlookup Command Nslookup is a program to query Internet domain name servers. Nslookup has two modes interactive and non-interactive.

Interactive mode allows the user to query name servers for information about various hosts and domains or to print a list of hosts in a domain.

Non-interactive mode is used to print just the name and requested information for a host or domain. It’s network administration tool which will help them to check and troubleshoot DNS related issues.

3) Check DNS Records Using Host Command host is a simple utility for performing DNS lookups. It is normally used to convert names to IP addresses and vice versa. When no arguments or options are given, host prints a short summary of its command line arguments and options.

I've used this successfully inside R script:

library("reshape2",lib.loc="/path/to/R-packages/")

useful if for whatever reason libraries are in more than one place.

In addition to Petr's answer, if you want to bind to a specific interface instead of all the interfaces you can use -b or --bind flag.

python -m http.server 8000 --bind 127.0.0.1

The above snippet should do the trick. 8000 is the port number. 80 is used as the standard port for HTTP communications.

With EF or LINQ to SQL:

var item = db.Items.OrderByDescending(i => i.Value).FirstOrDefault();

With LINQ to Objects I suggest to use morelinq extension MaxBy (get morelinq from nuget):

var item = items.MaxBy(i => i.Value);

The above answers are good and correct. However, the code may not give the expected results. Allow me to add something to explain why this is very important.

It is true that adding the scroll-behavior: smooth to the html element allows smooth scrolling for the whole page. However not all web browsers support smooth scrolling using HTML.

So if you want to create a website accessible to all user, regardless of their web browsers, it is highly recommended to use JavaScript or a JavaScript library such as jQuery, to create a solution that will work for all browsers.

Otherwise, some users may not enjoy the smooth scrolling of your website / platform.

I can give a simpler example on how it can be applicable.

Are you using Eclipse? If so I would stick with the default member sort order, because that is likely to be most familiar to whoever reads your code (although it is not my favourite sort order.)

You could use gitk --all and search for commits "touching paths" and the pathname you are interested in.

I don't know about the Android specifics for ssl certificates, but it would make sense that Android won't accept a self signed ssl certificate off the bat. I found this post from android forums which seems to be addressing the same issue: http://androidforums.com/android-applications/950-imap-self-signed-ssl-certificates.html

document.baseURI gives you the domain + port. It's used if an image tag uses a relative instead of an absolute path. Probably already solved, but it might be useful for other guys.

.NET 4.0+ has a generic Enum.TryParse

ContentEnum content;
Enum.TryParse(fileContentMessage, out content);

    DateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

    Date date = new Date();
    Date date2 = new Date("2014/08/06 15:59:48");

    String currentDate = dateFormat.format(date).toString();
    String anyDate = dateFormat.format(date2).toString();

    System.out.println(currentDate);
    System.out.println(anyDate);

I had the same problem, here's how I solved it. Following the first section of this very excellent Django tutorial, I did the following:

1. Create a new Django app by executing: python manage.py startapp new_app
2. Edit the settings.py file, adding the following to the list of INSTALLED_APPS: 'new_app',
3. Add a new module to the new_app package named new_app_tags.
4. In a Django HTML template, add the following to the top of the file, but after {% extends 'base_template_name.html' %}: {% load new_app_tags %}
5. In the new_app_tags module file, create a custom template tag (see below).
6. In the same Django HTML template, from step 4 above, use your shiney new custom tag like so: {% multiply_by_two | "5.0" %}
7. Celebrate!

Example from step 5 above:

from django import template

register = template.Library()

@register.simple_tag
def multiply_by_two(value):
    return float(value) * 2.0

If you save the excel file as a CSV file then you can import it into a mysql database using tools such as PHPMyAdmin

Im not sure if this would help in your situation, but a csv file either manually or programatically would be a lot easier to parse into a database than an excel file I would have thought.

EDIT: I would however suggest looking at the other answers rather than mine since @diEcho answer seems more appropriate.

Add the total row to your data collection that will be bound to the grid.

Use the built-in localized formats

If this is for showing a time of day to a user, then in at least 19 out of 20 you don’t need to care about kk, HH nor hh. I suggest that you use something like this:

    DateTimeFormatter defaultTimeFormatter
            = DateTimeFormatter.ofLocalizedTime(FormatStyle.SHORT);
    System.out.format("%s: %s%n",
            Locale.getDefault(), LocalTime.MIN.format(defaultTimeFormatter));

The point is that it gives different output in different default locales. For example:

en_SS: 12:00 AM
fr_BL: 00:00
ps_AF: 0:00
es_CO: 12:00 a.m.

The localized formats have been designed to conform with the expectations of different cultures. So they generally give the user a better experience and they save you of writing a format pattern string, which is always error-prone.

I furthermore suggest that you don’t use SimpleDateFormat. That class is notoriously troublesome and fortunately long outdated. Instead I use java.time, the modern Java date and time API. It is so much nicer to work with.

Four pattern letters for hour: H, h, k and K

Of course if you need to parse a string with a specified format, and also if you have a very specific formatting requirement, it’s good to use a format pattern string. There are actually four different pattern letters to choose from for hour (quoted from the documentation):

  Symbol  Meaning                     Presentation      Examples
  ------  -------                     ------------      -------
   h       clock-hour-of-am-pm (1-12)  number            12
   K       hour-of-am-pm (0-11)        number            0
   k       clock-hour-of-day (1-24)    number            24
   H       hour-of-day (0-23)          number            0

In practice H and h are used. As far as I know k and K are not (they may just have been included for the sake of completeness). But let’s just see them all in action:

    DateTimeFormatter timeFormatter
            = DateTimeFormatter.ofPattern("hh:mm a  HH:mm  kk:mm  KK:mm a", Locale.ENGLISH);
    System.out.println(LocalTime.of(0, 0).format(timeFormatter));
    System.out.println(LocalTime.of(1, 15).format(timeFormatter));
    System.out.println(LocalTime.of(11, 25).format(timeFormatter));
    System.out.println(LocalTime.of(12, 35).format(timeFormatter));
    System.out.println(LocalTime.of(13, 40).format(timeFormatter));

12:00 AM  00:00  24:00  00:00 AM
01:15 AM  01:15  01:15  01:15 AM
11:25 AM  11:25  11:25  11:25 AM
12:35 PM  12:35  12:35  00:35 PM
01:40 PM  13:40  13:40  01:40 PM

If you don’t want the leading zero, just specify one pattern letter, that is h instead of hh or H instead of HH. It will still accept two digits when parsing, and if a number to be printed is greater than 9, two digits will still be printed.

It allows you to use a C# keyword as a variable. For example:

class MyClass
{
   public string name { get; set; }
   public string @class { get; set; }
}

You could also use:

split=lambda x,n: x if not x else [x[:n]]+[split([] if not -(len(x)-n) else x[-(len(x)-n):],n)][0]

split([1,2,3,4,5,6,7,8,9],2)

[[1, 2], [3, 4], [5, 6], [7, 8], [9]]

foreach (int x in chklstTerms.CheckedIndices)
{
    chklstTerms.SelectedIndex=x;
    termids.Add(chklstTerms.SelectedValue.ToString());
}

You could use this:

data[:1] = ['hello']

An answer to your Question from 2019:

It depends on what version of ECMAScript you use.

Pre ES6:

Use any of the answers below, e.g.:

for (var m in myMap){
    for (var i=0;i<myMap[m].length;i++){
    ... do something with myMap[m][i] ...
    }
} 

For ES6 (ES 2015):

You should use a Map object, which has the entries() function:

var myMap = new Map();
myMap.set("0", "foo");
myMap.set(1, "bar");
myMap.set({}, "baz");

for (const [key, value] of myMap.entries()) {
  console.log(key, value);
}

For ES8 (ES 2017):

Object.entries() was introduced:

const object = {'a': 1, 'b': 2, 'c' : 3};
for (const [key, value] of Object.entries(object)) {
  console.log(key, value);
}

I think you just need to add 2 more options (contentType and dataType):

$('#my_get_related_keywords').click(function() {

    $.ajax({
            type: "POST",
            url: "HERE PUT THE PATH OF YOUR SERVICE OR PAGE",
            data: '{"HERE YOU CAN PUT DATA TO PASS AT THE SERVICE"}',
            contentType: "application/json; charset=utf-8", // this
            dataType: "json", // and this
            success: function (msg) {
               //do something
            },
            error: function (errormessage) {
                //do something else
            }
        });
}

A different way

$("#inline_content input[name='type']").change(function () {
    if ($(this).val() == "walk_in" && $(this).is(":checked")) {
        $('#select-table > .roomNumber').attr('enabled', false);
    }
});

Demo - http://jsfiddle.net/cB6xV/

In my opinion this is the simplest solution

$orderby = 'name';
                $order = 'asc';
                $hide_empty = false ;
                $cat_args = array(
                    'orderby'    => $orderby,
                    'order'      => $order,
                    'hide_empty' => $hide_empty,
                );

                $product_categories = get_terms( 'product_cat', $cat_args );

                if( !empty($product_categories) ){
                    echo '

                <ul>';
                    foreach ($product_categories as $key => $category) {
                        echo '

                <li>';
                        echo '<a href="'.get_term_link($category).'" >';
                        echo $category->name;
                        echo '</a>';
                        echo '</li>';
                    }
                    echo '</ul>


                ';
                }

If you want a CSV file then you can modify Lukas' solutions as follows (assuming you are on a linux box):

hive -e 'select books from table' | sed 's/[[:space:]]\+/,/g' > /home/lvermeer/temp.csv

You can use the shell for this purpose.

Set shl = CreateObject("WScript.Shell") 
shl.Run "cmd mkdir YourDir" & copy "

Here is a simple code snippet:

function getIndexOfSubStr(str, searchToken, preIndex, output) {
    var result = str.match(searchToken);
    if (result) {
        output.push(result.index +preIndex);
        str=str.substring(result.index+searchToken.length);
        getIndexOfSubStr(str, searchToken, preIndex, output)
    }
    return output;
}

var str = "my name is 'xyz' and my school name is 'xyz' and my area name is 'xyz' ";
var searchToken ="my";
var preIndex = 0;

console.log(getIndexOfSubStr(str, searchToken, preIndex, []));

You don't need one unless your class maintains unmanaged resources like Windows file handles.

• \n (Line Feed) → moves the cursor down to the next line without returning to the beginning of the line — In a *nix environment \n moves to the beginning of the line.
• \r\n (End Of Line) → a combination of \r and \n

Put [unowned self] before (text: String)... in your closure. This is called a capture list and places ownership instructions on symbols captured in the closure.

The following shows the declaration of an array, but the array is not initialized:

 int[] myIntArray = new int[3];

The following shows the declaration as well as initialization of the array:

int[] myIntArray = {1,2,3};

Now, the following also shows the declaration as well as initialization of the array:

int[] myIntArray = new int[]{1,2,3};

But this third one shows the property of anonymous array-object creation which is pointed by a reference variable "myIntArray", so if we write just "new int[]{1,2,3};" then this is how anonymous array-object can be created.

If we just write:

int[] myIntArray;

this is not declaration of array, but the following statement makes the above declaration complete:

myIntArray=new int[3];

You should create a header file like

// Constants.h
FOUNDATION_EXPORT NSString *const MyFirstConstant;
FOUNDATION_EXPORT NSString *const MySecondConstant;
//etc.

(you can use extern instead of FOUNDATION_EXPORT if your code will not be used in mixed C/C++ environments or on other platforms)

You can include this file in each file that uses the constants or in the pre-compiled header for the project.

You define these constants in a .m file like

// Constants.m
NSString *const MyFirstConstant = @"FirstConstant";
NSString *const MySecondConstant = @"SecondConstant";

Constants.m should be added to your application/framework's target so that it is linked in to the final product.

The advantage of using string constants instead of #define'd constants is that you can test for equality using pointer comparison (stringInstance == MyFirstConstant) which is much faster than string comparison ([stringInstance isEqualToString:MyFirstConstant]) (and easier to read, IMO).

If your database supports arrays, you can also implement a lineage column or materialized path as an array of parent ids.

Specifically with Postgres you can then use the set operators to query the hierarchy, and get excellent performance with GIN indices. This makes finding parents, children, and depth pretty trivial in a single query. Updates are pretty manageable as well.

I have a full write up of using arrays for materialized paths if you're curious.

just to extend @GabLeRoux's answer:

[<img src="https://img.youtube.com/vi/<VIDEO ID>/maxresdefault.jpg" width="50%">](https://youtu.be/<VIDEO ID>)

this way you will be able to adjust the size of the thumbnail image in the README.md file on you Github repo.

The above problem can be solved by adding the following dependencies in your project, as i was facing the same problem.For more detail answer to this solution please refer link SEVERE:MessageBodyWriter not found for media type=application/xml type=class java.util.HashMap

there are some mistakes in your code - the first: you havn't closed you p-tag:

<a href="http//www.google.com"><p style="text-align:center">Search</p></a>

next: p stands for 'paragraph' and is a block-element (so it's causing a line-break). what you wanted to use there is a span, wich is just an inline-element for formatting:

<a href="http//www.google.com"><span style="text-align:center">Search</span></a>

but if you just want to add a style to your link, why don't you set the style for that link directly:

<a href="http//www.google.com" style="text-align:center">Search</a>

in the end, this would at least be correct html, but still not exactly what you want, because text-align:center centers the text in that element, so you would have to set that for the element that contains this links (this piece of html isn't posted, so i can't correct you, but i hope you understand) - to show this, i'll use a simple div:

<div style="text-align:center">    
  <a href="http//www.google.com">Search</a>
  <!-- more links here -->
</div>

EDIT: some more additions to your question:

• p is not a 'function', but you're right, this is causing the problem (because it's a block-element)
• what you're trying to use is css - it's just inline instead of being placed in a seperate file, but you aren't doing 'just HTML' here

Check if the Node is a Dom Element, cast, and call getElementsByTagName()

Node doc = docs.item(i);
if(doc instanceof Element) {
    Element docElement = (Element)doc;
    ...
    cell = doc.getElementsByTagName("aoo").item(0);
}

Behind the curtain, enums are POJOs with a private constructor and a bunch of public static final values of the enum's type (see here for an example). In fact, up until Java5, it was considered best-practice to build your own enumeration this way, and Java5 introduced the enum keyword as a shorthand. See the source for Enum<T> to learn more.

So it should be no problem to write your own 'TypeSafeEnum' with a public static final array of constants, that are read by the constructor or passed to it.

Also, do yourself a favor and override equals, hashCode and toString, and if possible create a values method

The question is how to use such a dynamic enumeration... you can't read the value "PI=3.14" from a file to create enum MathConstants and then go ahead and use MathConstants.PI wherever you want...

This is because label is an inline element, and is therefore only as big as the text it contains.

The possible is to display your label as a block element like this:

#formItem label {
    display: block;
    text-align: center;
    line-height: 150%;
    font-size: .85em;
}

However, if you want to use the label on the same line with other elements, you either need to set display: inline-block; and give it an explicit width (which doesn't work on most browsers), or you need to wrap it inside a div and do the alignment in the div.

This works for me.

cp -r /home/server/folder/test/. /home/server

The for loop can only contain three parameters, you have used 4. Please restate the question, what do you want to achieve?

docker-push-ssh is a command line utility I created just for this scenario.

It sets up a temporary private Docker registry on the server, establishes an SSH tunnel from your localhost, pushes your image, then cleans up after itself.

The benefit of this approach over docker save (at the time of writing most answers are using this method) is that only the new layers are pushed to the server, resulting in a MUCH quicker upload.

Oftentimes using an intermediate registry like dockerhub is undesirable, and cumbersome.

https://github.com/brthor/docker-push-ssh

Install:

pip install docker-push-ssh

Example:

docker-push-ssh -i ~/my_ssh_key [email protected] my-docker-image

The biggest caveat is that you have to manually add your localhost to Docker's insecure_registries configuration. Run the tool once and it will give you an informative error:

Error Pushing Image: Ensure localhost:5000 is added to your insecure registries.

The Spl DirectoryIterator class provides a simple interface for viewing the contents of filesystem directories.

$dir = new DirectoryIterator($path);
foreach ($dir as $fileinfo) {
    if ($fileinfo->isDir() && !$fileinfo->isDot()) {
        echo $fileinfo->getFilename().'<br>';
    }
}

to stop IIS manually:

1. go to start menu
2. type in IIS

you get a search result for the manager (Internet Information Services (IIS) manager, on the right side of it there are restart/stop/start buttons.

If you don't want IIS to start on startup because its really annoying..:

1. go to start menu.
2. click control panel.
3. click programs.
4. turn windows features on or off
5. wait until the list is loaded
6. search for Internet Information Services (IIS).
7. uncheck the box.
8. Wait until it's done with the changes.
9. restart computer, but then again the info box will tell you to do that anyways (you can leave this for later if you want to).

oh and IIS and xampp basically do the same thing just in a bit different way. ANd if you have Xampp for your projects then its not really all that nessecary to leave it on if you don't ever use it anyways.

import csv

with open('filepath/filename.csv', "rt", encoding='ascii') as infile:
    read = csv.reader(infile)
    for row in read :
        print (row)

This will solve your problem. Don't forget to give the encoding.

This code will always fail.

As written, it says: "Look for a property named "Employee" on my DataContext property, and set it to the DataContext property". Clearly that isn't right.

To get your code to work, as is, change your window declaration to:

<Window x:Class="SampleApplication.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="clr-namespace:SampleApplication"
    Title="MainWindow" Height="350" Width="525">
<Window.DataContext>
   <local:Employee/>
</Window.DataContext>

This declares a new XAML namespace (local) and sets the DataContext to an instance of the Employee class. This will cause your bindings to display the default data (from your constructor).

However, it is highly unlikely this is actually what you want. Instead, you should have a new class (call it MainViewModel) with an Employee property that you then bind to, like this:

public class MainViewModel
{
   public Employee MyEmployee { get; set; } //In reality this should utilize INotifyPropertyChanged!
}

Now your XAML becomes:

<Window x:Class="SampleApplication.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:local="clr-namespace:SampleApplication"
        Title="MainWindow" Height="350" Width="525">
    <Window.DataContext>
       <local:MainViewModel/>
    </Window.DataContext>
    ...
    <TextBox Grid.Column="1" Grid.Row="0" Margin="3" Text="{Binding MyEmployee.EmpID}" />
    <TextBox Grid.Column="1" Grid.Row="1" Margin="3" Text="{Binding MyEmployee.EmpName}" />

Now you can add other properties (of other types, names), etc. For more information, see Implementing the Model-View-ViewModel Pattern

OK, I've found it. This is probably the cleanest and easiest solution out there and does not rely on JavaScript being turned on.

@-moz-document url-prefix() {

<h1>This should be red in FF</h1>

It's based on yet another Mozilla specific CSS extension. There's a whole list for these CSS extensions right here: Mozilla CSS Extensions.

Instead of using np.argsort you could use np.argpartition - if you only need the indices of the lowest/highest n elements.

That doesn't require to sort the whole array but just the part that you need but note that the "order inside your partition" is undefined, so while it gives the correct indices they might not be correctly ordered:

>>> avgDists = [1, 8, 6, 9, 4]
>>> np.array(avgDists).argpartition(2)[:2]  # indices of lowest 2 items
array([0, 4], dtype=int64)

>>> np.array(avgDists).argpartition(-2)[-2:]  # indices of highest 2 items
array([1, 3], dtype=int64)

# index dictionary by list of key names

def fn1():
    print "One"

def fn2():
    print "Two"

def fn3():
    print "Three"

fndict = {"A": fn1, "B": fn2, "C": fn3}

keynames = ["A", "B", "C"]

fndict[keynames[1]]()

# keynames[1] = "B", so output of this code is

# Two

With your question edit, I see your problem. Let's say the current directory is /home/yourname ... in this case, your command below:

sed 's/xxx/'$PWD'/'

will be expanded to

sed `s/xxx//home/yourname//

which is not valid. You need to put a \ character in front of each / in your $PWD if you want to do this.

Your question feels a little incomplete, but I think what you're looking for is a way of making your JSON accessible to your code:

if you have the JSON string as above then you'd just need to do this

var jsonObj = eval('[{"id":28,"Title":"Sweden"}, {"id":56,"Title":"USA"}, {"id":89,"Title":"England"}]');

then you can access these vars with something like jsonObj[0].id etc

Let me know if that's not what you were getting at and I'll try to help.

If you don't need any file further, you can decorate the test method:

@patch('builtins.open', mock_open(read_data="data"))
def test_testme():
    result = testeme()
    assert result == "data"

An alternative solution to that of @Aaron is the bquote() function. We need to supply a valid R expression, in this case LABEL ~ x^2 for example, where LABEL is the string you want to assign from the vector labNames. bquote evaluates R code within the expression wrapped in .( ) and subsitutes the result into the expression.

Here is an example:

labNames <- c('xLab','yLab')
xlab <- bquote(.(labNames[1]) ~ x^2)
ylab <- bquote(.(labNames[2]) ~ y^2)
plot(c(1:10), xlab = xlab, ylab = ylab)

(Note the ~ just adds a bit of spacing, if you don't want the space, replace it with * and the two parts of the expression will be juxtaposed.)

we could open html file from linux/unix by using firefox .html

Everything is mirrored on omapzoom.org. Some of the code is also mirrored on github.

Contacts is here for example.

Since December 2019, you can use the new official public code search tool for AOSP: cs.android.com. There's also the Android official source browser (based on Gitiles) has a web view of many of the different parts that make up android. Some of the projects (such as Kernel) have been removed and it now only points you to clonable git repositories.

To get all the code locally, you can use the repo helper program, or you can just clone individual repositories.

And others:

• Downloading the Source Tree

You could "simulate" shifting and masking: if((0x5e/(2*2*2))%2) ...

You can show whatever you want in list display by using a callable. It would look like this:

def book_author(object):
  return object.book.author

class PersonAdmin(admin.ModelAdmin):
  list_display = [book_author,]

Just in the controller call

return View('index');

In the Unix world, there were a few possible arrangements for the sizes of integers and pointers for 64-bit platforms. The two mostly widely used were ILP64 (actually, only a very few examples of this; Cray was one such) and LP64 (for almost everything else). The acronynms come from 'int, long, pointers are 64-bit' and 'long, pointers are 64-bit'.

Type           ILP64   LP64   LLP64
char              8      8       8
short            16     16      16
int              64     32      32
long             64     64      32
long long        64     64      64
pointer          64     64      64

The ILP64 system was abandoned in favour of LP64 (that is, almost all later entrants used LP64, based on the recommendations of the Aspen group; only systems with a long heritage of 64-bit operation use a different scheme). All modern 64-bit Unix systems use LP64. MacOS X and Linux are both modern 64-bit systems.

Microsoft uses a different scheme for transitioning to 64-bit: LLP64 ('long long, pointers are 64-bit'). This has the merit of meaning that 32-bit software can be recompiled without change. It has the demerit of being different from what everyone else does, and also requires code to be revised to exploit 64-bit capacities. There always was revision necessary; it was just a different set of revisions from the ones needed on Unix platforms.

If you design your software around platform-neutral integer type names, probably using the C99 <inttypes.h> header, which, when the types are available on the platform, provides, in signed (listed) and unsigned (not listed; prefix with 'u'):

• int8_t - 8-bit integers
• int16_t - 16-bit integers
• int32_t - 32-bit integers
• int64_t - 64-bit integers
• uintptr_t - unsigned integers big enough to hold pointers
• intmax_t - biggest size of integer on the platform (might be larger than int64_t)

You can then code your application using these types where it matters, and being very careful with system types (which might be different). There is an intptr_t type - a signed integer type for holding pointers; you should plan on not using it, or only using it as the result of a subtraction of two uintptr_t values (ptrdiff_t).

But, as the question points out (in disbelief), there are different systems for the sizes of the integer data types on 64-bit machines. Get used to it; the world isn't going to change.

My special case is:

previously start mongod by:

sudo -u mongod mongod -f /etc/mongod.conf

now, want to stop mongod.

and refer official doc Stop mongod Processes, has tried:

(1) shutdownServer but failed:

> use admin
switched to db admin
> db.shutdownServer()
2019-03-06T14:13:15.334+0800 E QUERY    [thread1] Error: shutdownServer failed: {

} :

DB.prototype.shutdownServer@src/mongo/shell/db.js:302:1
@(shell):1:1

(2) --shutdown still failed:

# mongod --shutdown
There doesn't seem to be a server running with dbpath: /data/db

(3) previous start command adding --shutdown:

sudo -u mongod mongod -f /etc/mongod.conf --shutdown
killing process with pid: 30213
failed to kill process: errno:1 Operation not permitted

(4) use service to stop:

service mongod stop

and

service mongod status

show expected Active: inactive (dead) but mongod actually still running, for can see process from ps:

# ps -edaf | grep mongo | grep -v grep
root     30213     1  0 Feb04 ?        03:33:22 mongod --port PORT --dbpath=/var/lib/mongo

and finally, really stop mongod by:

# sudo mongod -f /etc/mongod.conf --shutdown
killing process with pid: 30213

until now, root cause: still unknown ...

hope above solution is useful for your.

In the future one would use left: unset; for unsetting the value of left.

As of today 4 nov 2014 unset is only supported in Firefox.

Read more about unset in MDN.

My guess is we'll be able to use it around year 2022 when IE 11 is properly phased out.

I think this should do it for you.

assertThrows(someException.class, ()-> mockedServiceReference.someMethod(param1,parme2,..));

Is the browser supports it, using translate is powerful.

position: absolute;
background-color: red;

width: 70%;     
height: 30%; 

/* The translate % is relative to the size of the div and not the container*/ 
/* 21.42% = ( (100%-70%/2) / 0.7 ) */
/* 116.666% = ( (100%-30%/2) / 0.3 ) */
transform: translate3d( 21.42%, 116.666%, 0);

I have been similar problems. It would launch once and not a 2nd time under different tabs. I used a class instead of an id, and used the same class name everywhere. To me it appears datepicker activates once and the original initialization has to be used everywhere. One can probably code around this with the destroy api, but for me it was easy to simply use the same class everywhere.

If you really want to check for all those special characters, it's easier to use a regular expression:

var str = $('#Search').val();
if(/^[a-zA-Z0-9- ]*$/.test(str) == false) {
    alert('Your search string contains illegal characters.');
}

The above will only allow strings consisting entirely of characters on the ranges a-z, A-Z, 0-9, plus the hyphen an space characters. A string containing any other character will cause the alert.

Query objects in Mongo by default AND expressions together. Mongo currently does not include an OR operator for such queries, however there are ways to express such queries.

Use "in" or "where".

Its gonna be something like this:

db.mycollection.find( { $where : function() { 
return ( this.startTime < Now() && this.expireTime > Now() || this.expireTime == null ); } } );

It is due to OS

In your package.json, make sure to have your scripts(Where app.js is your main js file to be executed & NODE_ENV is declared in a .env file).Eg:

"scripts": {
    "start": "node app.js",
    "dev": "nodemon server.js",
    "prod": "NODE_ENV=production & nodemon app.js"
  }

For windows

Also set up your .env file variable having NODE_ENV=development

If your .env file is in a folder for eg.config folder make sure to specify in app.js(your main js file)

const dotenv = require('dotenv'); dotenv.config({ path: './config/config.env' });

Basically,

DTO: "Data transfer objects " can travel between seperate layers in software architecture.

VO: "Value objects " hold a object such as Integer,Money etc.

POJO: Plain Old Java Object which is not a special object.

Java Beans: requires a Java Class to be serializable, have a no-arg constructor and a getter and setter for each field

Just to add, I am using self object, this worked for me:

[f.name for f in self.model._meta.get_fields()]

Your task declaration is incorrectly combining the Copy task type and project.copy method, resulting in a task that has nothing to copy and thus never runs. Besides, Copy isn't the right choice for renaming a directory. There is no Gradle API for renaming, but a bit of Groovy code (leveraging Java's File API) will do. Assuming Project1 is the project directory:

task renABCToXYZ {     doLast {         file("ABC").renameTo(file("XYZ"))     } } 

Looking at the bigger picture, it's probably better to add the renaming logic (i.e. the doLast task action) to the task that produces ABC.

Update the pom.xml as -

<project>

    <build>
      <resources>
        <resource>
          <directory>src/main/config</directory>
        </resource>
      </resources>
     ...
    </build>
...

I encountered the same error but the problem turned out to be because I had created a new configuration in my solution that didn't exist in referenced assemblies from another solution.

This can be resolved by opening the related solution and adding the new configuration to it as well.

This post gave me the idea to check the referenced assemblies after I'd already confirmed that all projects within my solution had the correct configuration:

You could also use the linux sh command and pass it a command that includes the redirection:

string cmd = "/bin/ls > " + filepath;

execl("/bin/sh", "sh", "-c", cmd.c_str(), 0);

Like @Maximiliangerhardt said, MiniJson do not have the capability to deserialize properly. I used JsonFx and works like a charm. Works with the []

player[] p = JsonReader.Deserialize<player[]>(serviceData);
Debug.Log(p[0].playerId +" "+ p[0].playerLoc+"--"+ p[1].playerId + " " + p[1].playerLoc+"--"+ p[2].playerId + " " + p[2].playerLoc);

Use Ctrl+K. This goes clean your console in Visual Studio Code.

Per comments, in later versions of VSCode (1.29 and above) this shortcut is missing / needs to be created manually.

• Navigate: File > Preferences > Keyboard Shortcuts
• search for workbench.action.terminal.clear
• If it has no mapping or you wish to change the mapping, continue; otherwise note & use the existing mapping
• Double click on this entry & you'll be prompted for a key binding. Hold CTRL and tap K. Ctrl + K should now be listed. Press enter to save this mapping
• Right click the entry and select Change when expression. Type terminalFocus then press enter.
• That's it. Now, when the terminal is in focus and you press ctrl+k you'll get the behaviour you'd have expected to get from running clear/cls.

Just replace, with replace().

f = float("123,456.908".replace(',','')) print(type(f)

type() will show you that it has converted into a float

You can run the sleep command before your ExecStart with ExecStartPre :

[Service]
ExecStartPre=/bin/sleep 30

Prior to PHP 5.3.6, the charset option was ignored. If you're running an older version of PHP, you must do it like this:

<?php

    $dbh = new PDO("mysql:$connstr",  $user, $password);

    $dbh -> exec("set names utf8");

?>

EDIT:

Ok I found why the int.ToString() in LINQtoEF fails, please read this post: Problem with converting int to string in Linq to entities

This works on my side :

        List<string> materialTypes = (from u in result.Users
                                      select u.LastName)
                       .Union(from u in result.Users
                               select SqlFunctions.StringConvert((double) u.UserId)).ToList();

On yours it should be like this:

    IList<String> materialTypes = ((from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select tom.Name)
                                       .Union(from tom in context.MaterialTypes
                                       where tom.IsActive == true
                                       select SqlFunctions.StringConvert((double)tom.ID))).ToList();

Thanks, i've learnt something today :)

If you are like me just want to print a sequence within a lambda, without get the return value (list of None).

x = range(3)
from __future__ import print_function           # if not python 3
pra = lambda seq=x: map(print,seq) and None     # pra for 'print all'
pra()
pra('abc')

If this is really bothering you, why not write your own method isBetween(orderBean.getFiles().size(),0,5)?

Another option is to use isEmpty as it is a tad clearer:

if(!orderBean.getFiles().isEmpty() && orderBean.getFiles().size() < 5)

Do you mean like this?

var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);

To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll() to accomplish this:

HTML

<div class="abc"></div>
<div class="abc"></div>

JS

var abcElements = document.querySelectorAll('.abc');

// Set their ids
for (var i = 0; i < abcElements.length; i++)
    abcElements[i].id = 'abc-' + i;

This will assign the ID 'abc-<index number>' to each element. So it would come out like this:

<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>

To create an element and assign an id we can use document.createElement() and then appendChild().

var div = document.createElement('div');
div.id = 'hello1';

var body = document.querySelector('body');
body.appendChild(div);

Update

You can set the id on your element like this if your script is in your HTML file.

<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">

<script type="text/javascript">
    var s = document.getElementsByClassName('assign-me')[0];
    s.id = btoa({{str(produit["avt"]["fto"])}});
</script>

Your requirements still aren't 100% clear though.

I had the same issue on linux, but I couldn't fix it with the accepted answer. I was able to solve it by using cd to go to the correct folder and then executing:

svn remove --force filename  
syn resolve --accept=working filename  
svn up

That's all.

I have seen this error while trying to install rhodecode to a virtualenv on ubuntu 13.10. For me the solution was to run

pip install --upgrade setuptools
pip install --upgrade distribute 

before I run easy_install rhodecode.

Sample Ubuntu-based build for ccache:

sudo apt-get update
sudo apt-get build-dep ccache
apt-get -b source ccache
sudo dpkg -i ccache*.deb

More details: http://blog.aplikacja.info/2011/11/building-packages-from-sources-in-debianubuntu/

I suggest using vlookup function to get the nearest match.

Step 1

Prepare data range and name it: 'numberRange':

Select the range. Go to menu: Data ? Named ranges... ? define the new named range.

Step 2

Use this simple formula:

=VLOOKUP(A2,numberRange,2)

This way you can ommit errors, and easily correct the result.

i would recommend using this:

  background-repeat:no-repeat;
  background-image: url(your file location here);
  background-size:cover;(will only work with css3)

hope it helps :D

And if this doesnt support your needs just say it: i can make a jquery for multibrowser support.

TLDR:

hostname=XXX
port=443
trust_cert_file_location=`curl-config --ca`

sudo bash -c "echo -n | openssl s_client -showcerts -connect $hostname:$port -servername $hostname \
    2>/dev/null  | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'  \
    >> $trust_cert_file_location"

Long answer

The basic reason is that your computer doesn't trust the certificate authority that signed the certificate used on the Gitlab server. This doesn't mean the certificate is suspicious, but it could be self-signed or signed by an institution/company that isn't in the list of your OS's list of CAs. What you have to do to circumvent the problem on your computer is telling it to trust that certificate - if you don't have any reason to be suspicious about it.

You need to check the web certificate used for your gitLab server, and add it to your </git_installation_folder>/bin/curl-ca-bundle.crt.

To check if at least the clone works without checking said certificate, you can set:

export GIT_SSL_NO_VERIFY=1
#or
git config --global http.sslverify false

But that would be for testing only, as illustrated in "SSL works with browser, wget, and curl, but fails with git", or in this blog post.

Check your GitLab settings, a in issue 4272.

To get that certificate (that you would need to add to your curl-ca-bundle.crt file), type a:

echo -n | openssl s_client -showcerts -connect yourserver.com:YourHttpsGitlabPort \
  2>/dev/null  | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'

(with 'yourserver.com' being your GitLab server name, and YourHttpsGitlabPort is the https port, usually 443)

To check the CA (Certificate Authority issuer), type a:

echo -n | openssl s_client -showcerts -connect yourserver.com:YourHttpsGilabPort \
  2>/dev/null  | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' \
  | openssl x509 -noout -text | grep "CA Issuers" | head -1

Note: Valeriy Katkov suggests in the comments to add -servername option to the openssl command, otherwise the command isn't showed certificate for www.github.com in Valeriy's case.

openssl s_client -showcerts -servername www.github.com -connect www.github.com:443

Findekano adds in the comments:

to identify the location of curl-ca-bundle.crt, you could use the command

curl-config --ca

Also, see my more recent answer "github: server certificate verification failed": you might have to renistall those certificates:

sudo apt-get install --reinstall ca-certificates
sudo mkdir /usr/local/share/ca-certificates/cacert.org
sudo wget -P /usr/local/share/ca-certificates/cacert.org http://www.cacert.org/certs/root.crt http://www.cacert.org/certs/class3.crt
sudo update-ca-certificates
git config --global http.sslCAinfo /etc/ssl/certs/ca-certificates.crt

In addition to using pure threads or the Celery queue (note that flask-celery is no longer required), you could also have a look at flask-apscheduler:

https://github.com/viniciuschiele/flask-apscheduler

A simple example copied from https://github.com/viniciuschiele/flask-apscheduler/blob/master/examples/jobs.py:

from flask import Flask
from flask_apscheduler import APScheduler


class Config(object):
    JOBS = [
        {
            'id': 'job1',
            'func': 'jobs:job1',
            'args': (1, 2),
            'trigger': 'interval',
            'seconds': 10
        }
    ]

    SCHEDULER_API_ENABLED = True


def job1(a, b):
    print(str(a) + ' ' + str(b))

if __name__ == '__main__':
    app = Flask(__name__)
    app.config.from_object(Config())

    scheduler = APScheduler()
    # it is also possible to enable the API directly
    # scheduler.api_enabled = True
    scheduler.init_app(app)
    scheduler.start()

    app.run()

Short Extension Method:

public static TResult IfNotNull<TInput, TResult>(this TInput o, Func<TInput, TResult> evaluator)
  where TResult : class where TInput : class
{
  if (o == null) return null;
  return evaluator(o);
}

Using

PropertyC value = ObjectA.IfNotNull(x => x.PropertyA).IfNotNull(x => x.PropertyB).IfNotNull(x => x.PropertyC);

This simple extension method and much more you can find on http://devtalk.net/csharp/chained-null-checks-and-the-maybe-monad/

EDIT:

After using it for moment I think the proper name for this method should be IfNotNull() instead of original With().

What you seem to want would allow for a static method to be called via both the Type or any instance of that type. This would at very least result in ambiguity which is not a desirable trait.

There would be endless debates about whether it mattered, which is best practice and whether there are performance issues doing it one way or another. By simply not supporting it C# saves us having to worry about it.

Its also likely that a compilier that conformed to this desire would lose some optimisations that may come with a more strict separation between instance and static methods.

You can plot several columns at once by supplying a list of column names to the plot's y argument.

df.plot(x="X", y=["A", "B", "C"], kind="bar")

This will produce a graph where bars are sitting next to each other.

In order to have them overlapping, you would need to call plot several times, and supplying the axes to plot to as an argument ax to the plot.

import pandas as pd
import matplotlib.pyplot as plt
import numpy as np

y = np.random.rand(10,4)
y[:,0]= np.arange(10)
df = pd.DataFrame(y, columns=["X", "A", "B", "C"])

ax = df.plot(x="X", y="A", kind="bar")
df.plot(x="X", y="B", kind="bar", ax=ax, color="C2")
df.plot(x="X", y="C", kind="bar", ax=ax, color="C3")

plt.show()

DELETE FROM deadline where ID IN (
    SELECT d.ID FROM `deadline` d LEFT JOIN `job` ON deadline.job_id = job.job_id WHERE `status` =  'szamlazva' OR `status` = 'szamlazhato' OR `status` = 'fizetve' OR `status` = 'szallitva' OR `status` = 'storno');

I am not sure if that kind of sub query works in MySQL, but try it. I am assuming you have an ID column in your deadline table.

In my case the problem was that a method was defined in some Interface A as default, while its sub-class overrode it as private. Then when the method was called, the java Runtime realized it was calling a private method.

I am still puzzled as to why the compiler didn't complain about the private override..

public interface A {
     default void doStuff() {
         // doing stuff
     }
}

public class B {
     private void doStuff() {
         // do other stuff instead
     }
}

public static final main(String... args) {
    A someB = new B();
    someB.doStuff();
}

The translation is correct, the typing of the expression isn't. TypeScript is incorrectly typing the expression new Thing[100] as an array. It should be an error to index Thing, a constructor function, using the index operator. In C# this would allocate an array of 100 elements. In JavaScript this calls the value at index 100 of Thing as if was a constructor. Since that values is undefined it raises the error you mentioned. In JavaScript and TypeScript you want new Array(100) instead.

You should report this as a bug on CodePlex.

Expanding on betabandido's answer, you could write a function to inject the attributes as constants into the module:

def module_register_class_constants(klass, attr_prefix):
    globals().update(
        (name, getattr(klass, name)) for name in dir(klass) if name.startswith(attr_prefix)
    )

class Animal(object):
    SIZE_HUGE = "Huge"
    SIZE_BIG = "Big"

module_register_class_constants(Animal, "SIZE_")

class Horse(Animal):
    def printSize(self):
        print SIZE_BIG

I think clang could be an alternative.

GCC and clang have some differences on expressions like a+++++a, and I've got many different answers with my peer who use clang on Mac while I use gcc.

GCC has become the standard, and clang could be an alternative. Because GCC is very stable and clang is still under developing.

In my case, I had the Any XHR flag set true on the XHR Breakpoints settings, accessible over the Sources tab within Chrome's dev tools.

Uncheck it for Chrome to work normally again.

Using the join operator you can only perform equijoins. Other types of joins can be constructed using other operators. I'm not sure whether the exact join you are trying to do would be easier using these methods or by changing the where clause. Documentation on the join clause can be found here. MSDN has an article on join operations with multiple links to examples of other joins, as well.

You can find the number of characters using system function LEN. i.e.

SELECT LEN(Column) FROM TABLE

in batch file abc.bat

cd c:\user\ben_dchost\documents\
executible.exe -flag1 -flag2 -flag3 

I am assuming that your executible.exe is present in c:\user\ben_dchost\documents\ I am also assuming that the parameters it takes are -flag1 -flag2 -flag3

Edited:

For the command you say you want to execute, do:

cd C:\Users\Ben\Desktop\BGInfo\
bginfo.exe dc_bginfo.bgi
pause

Hope this helps

extern tells the compiler that this data is defined somewhere and will be connected with the linker.

With the help of the responses here and talking to a few friends here is the practical example of a use of extern.

Example 1 - to show a pitfall:

File stdio.h:

int errno;
/* other stuff...*/

myCFile1.c:
#include <stdio.h>

Code...

myCFile2.c:
#include <stdio.h>

Code...

If myCFile1.o and myCFile2.o are linked, each of the c files have separate copies of errno. This is a problem as the same errno is supposed to be available in all linked files.

Example 2 - The fix.

File stdio.h:

extern int errno;
/* other stuff...*/

File stdio.c

int errno;

myCFile1.c:
#include <stdio.h>

Code...

myCFile2.c:
#include <stdio.h>

Code...

Now if both myCFile1.o and MyCFile2.o are linked by the linker they will both point to the same errno. Thus, solving the implementation with extern.

use this code (in console mode):

Gem::Specification.all_names

For me, I had set my project to run on the latest version of .Net Framework (a change from .Net Framework 4.6.1 to 4.7.2).

Everything worked, no errors and published without issue, and it was only by chance that I came across the System.Net.Http error message, shown in a small, hard-to-notice, but quite important API request over the website I'm working on.

I rolled back to 4.6.1 and everything is fine again.

int.Parse(string s)

• Integer in RANGE > returns integer value
• Null value > ArguementNullException
• Not in format > FormatException
• Value not in RANGE > OverflowException

Convert.ToInt32(string s)

• Integer in RANGE > returns integer value
• Null value > returns "0"
• Not in format > FormatException
• Value not in RANGE > OverflowException

bool isParsed = int.TryParse(string s,out res)

• Integer in RANGE > returns integer value, isParsed = true
• Null value > returns "0", isParsed = false
• Not in format > returns "0", isParsed = false
• Value not in RANGE > returns "0", isParsed = false

Try this code below.....

class Program
{
    static void Main(string[] args)
    {
        string strInt = "24532";
        string strNull = null;
        string strWrongFrmt = "5.87";
        string strAboveRange = "98765432123456";
        int res;
        try
        {
            // int.Parse() - TEST
            res = int.Parse(strInt); // res = 24532
            res = int.Parse(strNull); // System.ArgumentNullException
            res = int.Parse(strWrongFrmt); // System.FormatException
            res = int.Parse(strAboveRange); // System.OverflowException

            // Convert.ToInt32(string s) - TEST
            res = Convert.ToInt32(strInt); // res = 24532
            res = Convert.ToInt32(strNull); // res = 0
            res = Convert.ToInt32(strWrongFrmt); // System.FormatException
            res = Convert.ToInt32(strAboveRange); //System.OverflowException

            // int.TryParse(string s, out res) - Test
            bool isParsed;
            isParsed = int.TryParse(strInt, out res); // isParsed = true, res = 24532
            isParsed = int.TryParse(strNull, out res); // isParsed = false, res = 0
            isParsed = int.TryParse(strWrongFrmt, out res); // isParsed = false, res = 0
            isParsed = int.TryParse(strAboveRange, out res); // isParsed = false, res = 0 
        }
        catch(Exception e)
        {
            Console.WriteLine("Check this.\n" + e.Message);
        }
    }

Add something like this to lib/__init__.py

from .helperclass import Helper

now you can import it directly:

from lib import Helper

You need to turn this into a string. You can do this using the stringify method in the JSON2 library.

http://www.json.org/

http://www.json.org/js.html

The code would look something like:

var myJSONText = JSON.stringify(myObject);

So

['Location Zero', 'Location One', 'Location Two'];

Will become:

"['Location Zero', 'Location One', 'Location Two']"

You'll have to refer to a PHP guru on how to handle this on the server. I think other answers here intimate a solution.

Data can be returned from the server in a similar way. I.e. you can turn it back into an object.

var myObject = JSON.parse(myJSONString);

You do it exactly the same way as you would with an element directive. You will have them in the attrs object, my sample has them two-way binding via the isolate scope but that's not required. If you're using an isolated scope you can access the attributes with scope.$eval(attrs.sample) or simply scope.sample, but they may not be defined at linking depending on your situation.

app.directive('sample', function () {
    return {
        restrict: 'A',
        scope: {
            'sample' : '=',
            'another' : '='
        },
        link: function (scope, element, attrs) {
            console.log(attrs);
            scope.$watch('sample', function (newVal) {
                console.log('sample', newVal);
            });
            scope.$watch('another', function (newVal) {
                console.log('another', newVal);
            });
        }
    };
});

used as:

<input type="text" ng-model="name" placeholder="Enter a name here">
<input type="text" ng-model="something" placeholder="Enter something here">
<div sample="name" another="something"></div>

class PushObjects {
    testMethod(): Array<number> { 
        //declaration and initialisation of array onject
        var objs: number[] = [1,2,3,4,5,7];
        //push the elements into the array object
        objs.push(100);
        //pop the elements from the array
        objs.pop();
        return objs;
    }   
}

let pushObj = new PushObjects();
//create the button element from the dom object 
let btn = document.createElement('button');
//set the text value of the button
btn.textContent = "Click here";
//button click event
btn.onclick = function () { 

    alert(pushObj.testMethod());

} 

document.body.appendChild(btn);

When objects are instantiated, the object itself is passed into the self parameter.

Because of this, the object’s data is bound to the object. Below is an example of how you might like to visualize what each object’s data might look. Notice how ‘self’ is replaced with the objects name. I'm not saying this example diagram below is wholly accurate but it hopefully with serve a purpose in visualizing the use of self.

The Object is passed into the self parameter so that the object can keep hold of its own data.

Although this may not be wholly accurate, think of the process of instantiating an object like this: When an object is made it uses the class as a template for its own data and methods. Without passing it's own name into the self parameter, the attributes and methods in the class would remain as a general template and would not be referenced to (belong to) the object. So by passing the object's name into the self parameter it means that if 100 objects are instantiated from the one class, they can all keep track of their own data and methods.

See the illustration below:

git revert -m allows to un-merge still keeping the history of both merge and un-do operation. Might be good for documenting probably.

I am not sure what you mean by "dynamic". If you mean adding items to a dictionary at runtime, it is as easy as dictionary[key] = value.

If you wish to create a dictionary with key,value to start with (at compile time) then use (surprise!)

dictionary[key] = value

If you want to add a single column after a specific field, then the following MySQL query should work:

ALTER TABLE users
    ADD COLUMN count SMALLINT(6) NOT NULL
    AFTER lastname

If you want to add multiple columns, then you need to use 'ADD' command each time for a column. Here is the MySQL query for this:

ALTER TABLE users
    ADD COLUMN count SMALLINT(6) NOT NULL,
    ADD COLUMN log VARCHAR(12) NOT NULL,
    ADD COLUMN status INT(10) UNSIGNED NOT NULL
    AFTER lastname

Point to note

In the second method, the last ADD COLUMN column should actually be the first column you want to append to the table.

E.g: if you want to add count, log, status in the exact order after lastname, then the syntax would actually be:

ALTER TABLE users
    ADD COLUMN log VARCHAR(12) NOT NULL AFTER lastname,
    ADD COLUMN status INT(10) UNSIGNED NOT NULL AFTER lastname,
    ADD COLUMN count SMALLINT(6) NOT NULL AFTER lastname
    

Make sure you add this option:

getSupportActionBar().setDisplayOptions(ActionBar.DISPLAY_SHOW_TITLE);

Something likes this

public void testPrintOut() {
    int val1 = 8;
    String val2 = "$951.23";
    String val3 = "$215.92";
    String val4 = "$198,301.22";
    System.out.println(String.format("%03d %7s %7s %11s", val1, val2, val3, val4));

    val1 = 9;
    val2 = "$950.19";
    val3 = "$216.95";
    val4 = "$198,084.26";
    System.out.println(String.format("%03d %7s %7s %11s", val1, val2, val3, val4));
}

Chain selectors are not limited just to classes, you can do it for both classes and ids.

Classes

.classA.classB {
/*style here*/
}

Class & Id

.classA#idB {
/*style here*/
}

Id & Id

#idA#idB {
/*style here*/
}

All good current browsers support this except IE 6, it selects based on the last selector in the list. So ".classA.classB" will select based on just ".classB".

For your case

li.left.ui-class-selector {
/*style here*/
}

or

.left.ui-class-selector {
/*style here*/
}

//Just in one line custom function
function cmp($a, $b)
{
return (float) $a['price'] < (float)$b['price'];
}
@uasort($inventory, "cmp");
print_r($inventory);

//result

Array
(
[2] => Array
    (
        [type] => pork
        [price] => 5.43
    )

[0] => Array
    (
        [type] => fruit
        [price] => 3.5
    )

[1] => Array
    (
        [type] => milk
        [price] => 2.9
    )

JDK is the SDK for Java.

SDK stands for 'Software Development Kit', a developers tools that enables one to write the code with more more ease, effectiveness and efficiency. SDKs come for various languages. They provide a lot of APIs (Application Programming Interfaces) that makes the programmer's work easy.

The SDK for Java is called as JDK, the Java Development Kit. So by saying SDK for Java you are actually referring to the JDK.

Assuming that you are new to Java, there is another term that you'll come across- JRE, the acronym for Java Runtime Environment. JRE is something that you need when you try to run software programs written in Java.

Java is a platform independent language. The JRE runs the JVM, the Java Virtual Machine, that enables you to run the software on any platform for which the JVM is available.

From the C99 standard (C++ should be the same, barring strange overloading)

6.5.2.4 Postfix increment and decrement operators

Constraints

1 The operand of the postfix increment or decrement operator shall have qualified or unqualified real or pointer type and shall be a modifiable lvalue.

Semantics

2 The result of the postfix ++ operator is the value of the operand. After the result is obtained, the value of the operand is incremented. (That is, the value 1 of the appropriate type is added to it.) See the discussions of additive operators and compound assignment for information on constraints, types, and conversions and the effects of operations on pointers. The side effect of updating the stored value of the operand shall occur between the previous and the next sequence point.

3 The postfix -- operator is analogous to the postfix ++ operator, except that the value of the operand is decremented (that is, the value 1 of the appropriate type is subtracted from it).

6.5.3.1 Prefix increment and decrement operators

Constraints

1 The operand of the prefix increment or decrement operator shall have qualified or unqualified real or pointer type and shall be a modifiable lvalue.

Semantics

2 The value of the operand of the prefix ++ operator is incremented. The result is the new value of the operand after incrementation. The expression ++E is equivalent to (E+=1). See the discussions of additive operators and compound assignment for information on constraints, types, side effects, and conversions and the effects of operations on pointers.

3 The prefix -- operator is analogous to the prefix ++ operator, except that the value of the operand is decremented.

If you wanna do it in case-insensitive way, this is better:

System.out.println(test.matches("^(?i)(https?|ftp)://.*$")); 

Here is an article with live working demo Class Animation In JQuery

You can try this,

$(function () {
   $("#btnSubmit").click(function () {
   $("#btnClass").removeClass("btnDiv").addClass("btn");
   });
});

you can also use switchClass() method - it allows you to animate the transition of adding and removing classes at the same time.

$(function () {
        $("#btnSubmit").click(function () {
            $("#btnClass").switchClass("btn", "btnReset", 1000, "easeInOutQuad");
        });
    });

In case the formatting needs to be done on Crystal Report side.

Simple way.

Crystal Report Design Window->Right click on the date field->format Field->Customize the date format per your need.

Works effectively.

Handling key events consistently is not at all easy.

Firstly, there are two different types of codes: keyboard codes (a number representing the key on the keyboard the user pressed) and character codes (a number representing a Unicode character). You can only reliably get character codes in the keypress event. Do not try to get character codes for keyup and keydown events.

Secondly, you get different sets of values in a keypress event to what you get in a keyup or keydown event.

I recommend this page as a useful resource. As a summary:

If you're interested in detecting a user typing a character, use the keypress event. IE bizarrely only stores the character code in keyCode while all other browsers store it in which. Some (but not all) browsers also store it in charCode and/or keyCode. An example keypress handler:

function(evt) {
  evt = evt || window.event;
  var charCode = evt.which || evt.keyCode;
  var charStr = String.fromCharCode(charCode);
  alert(charStr);
}

If you're interested in detecting a non-printable key (such as a cursor key), use the keydown event. Here keyCode is always the property to use. Note that keyup events have the same properties.

function(evt) {
  evt = evt || window.event;
  var keyCode = evt.keyCode;

  // Check for left arrow key
  if (keyCode == 37) {
    alert("Left arrow");
  }
}

This works:

var form = $(this).closest('form');

form = form.serializeArray();

form = form.concat([
    {name: "customer_id", value: window.username},
    {name: "post_action", value: "Update Information"}
]);

$.post('/change-user-details', form, function(d) {
    if (d.error) {
        alert("There was a problem updating your user details")
    } 
});

The best way is probably trying to open it, using just opendir() for instance.

Note that it's always best to try to use a filesystem resource, and handling any errors occuring because it doesn't exist, rather than just checking and then later trying. There is an obvious race condition in the latter approach.

For my situation, I switched the value of "fork" to false, such as <fork>false</fork>. I do not understand why, hope someone could explain to me. Thanks in advance.

Your program crashes because it used memory that does not belong to you. It may be used by someone else or not - if you are lucky you crash, if not the problem may stay hidden for a long time and come back and bite you later.

As far as malloc/free implementation goes - entire books are devoted to the topic. Basically the allocator would get bigger chunks of memory from the OS and manage them for you. Some of the problems an allocator must address are:

• How to get new memory
• How to store it - ( list or other structure, multiple lists for memory chunks of different size, and so on )
• What to do if the user requests more memory than currently available ( request more memory from OS, join some of the existing blocks, how to join them exactly, ... )
• What to do when the user frees memory
• Debug allocators may give you bigger chunk that you requested and fill it some byte pattern, when you free the memory the allocator can check if wrote outside of the block ( which is probably happening in your case) ...

Step by step:

# import numpy library
import numpy as np
# create list
my_list = [0,0,1,1,2,2,3,3]
# convert list to numpy array
np_array=np.asarray(my_list)
# reshape array into 4 rows x 2 columns, and transpose the result
reshaped_array = np_array.reshape(4, 2).T 

#check the result
reshaped_array
array([[0, 1, 2, 3],
       [0, 1, 2, 3]])

SQL Server does not track the order of inserted rows, so there is no reliable way to get that information given your current table structure. Even if employee_id is an IDENTITY column, it is not 100% foolproof to rely on that for order of insertion (since you can fill gaps and even create duplicate ID values using SET IDENTITY_INSERT ON). If employee_id is an IDENTITY column and you are sure that rows aren't manually inserted out of order, you should be able to use this variation of your query to select the data in sequence, newest first:

SELECT 
   ROW_NUMBER() OVER (ORDER BY EMPLOYEE_ID DESC) AS ID, 
   EMPLOYEE_ID,
   EMPLOYEE_NAME 
FROM dbo.CSBCA1_5_FPCIC_2012_EES207201222743
ORDER BY ID;

You can make a change to your table to track this information for new rows, but you won't be able to derive it for your existing data (they will all me marked as inserted at the time you make this change).

ALTER TABLE dbo.CSBCA1_5_FPCIC_2012_EES207201222743 
-- wow, who named this?
  ADD CreatedDate DATETIME NOT NULL DEFAULT CURRENT_TIMESTAMP;

Note that this may break existing code that just does INSERT INTO dbo.whatever SELECT/VALUES() - e.g. you may have to revisit your code and define a proper, explicit column list.

NodeJS supports http.request as a standard module: http://nodejs.org/docs/v0.4.11/api/http.html#http.request

var http = require('http');

var options = {
  host: 'example.com',
  port: 80,
  path: '/foo.html'
};

http.get(options, function(resp){
  resp.on('data', function(chunk){
    //do something with chunk
  });
}).on("error", function(e){
  console.log("Got error: " + e.message);
});

The only way to do it is by checking the value of the isCancelled() method and stopping playback when it returns true.

You can do this with a single call, like so:

scanf( "%i %i %i %i", &minx, &maxx, &miny, &maxy);

Or you can use:

echo "1: " | awk  '/1/{print $1-":"}' 

This is a really funny equation.

I got the same problem. I used a third-part library. When I compile this library, the compiler (gcc/clang) will complain about unused variables.

Like this

test.cpp:29:11: warning: variable 'magic' set but not used [-Wunused-but-set-variable] short magic[] = {

test.cpp:84:17: warning: unused variable 'before_write' [-Wunused-variable] int64_t before_write = Thread::currentTimeMillis();

So the solution is pretty clear. Adding -Wno-unused as gcc/clang CFLAG will suppress all "unused" warnings, even thought you have -Wall set.

In this way, you DO NOT NEED to change any code.

This is everything you need:

$week_start = strtotime('last Sunday', time());
$week_end = strtotime('next Sunday', time());

$month_start = strtotime('first day of this month', time());
$month_end = strtotime('last day of this month', time());

$year_start = strtotime('first day of January', time());
$year_end = strtotime('last day of December', time());

echo date('D, M jS Y', $week_start).'<br/>';
echo date('D, M jS Y', $week_end).'<br/>';

echo date('D, M jS Y', $month_start).'<br/>';
echo date('D, M jS Y', $month_end).'<br/>';

echo date('D, M jS Y', $year_start).'<br/>';
echo date('D, M jS Y', $year_end).'<br/>';

Try this tutorial it has the explanation and it will be helpful http://www.ccs.neu.edu/home/kathleen/classes/cs3200/JDBCtutorial.pdf

Another possible fix (solved my problem)

You might have configured the environment properly but for some reason it broke along the way. In this case go to:

file > project settings > modules

Deploy the list of SDKs and look for a red line with [invalid] at the end. If you find one, you have to recreate a python sdk.

It is likely that your previously working SDK is there too, but not red. Delete it.

Now you can click on the new button and add your favorite python virtualenv. And it should work now.

Use \overleftarrow to create a long arrow to the left.

\overleftarrow{blahblahblah}

You can use \blacksquare ¦:

When creating TeX, Knuth provided the symbol ¦ (solid black square), also called by mathematicians tombstone or Halmos symbol (after Paul Halmos, who pioneered its use as an equivalent of Q.E.D.). The tombstone is sometimes open: ? (hollow black square).

Using DataFlow as svick suggested may be overkill, and Stephen's answer does not provide the means to control the concurrency of the operation. However, that can be achieved rather simply:

public static async Task RunWithMaxDegreeOfConcurrency<T>(
     int maxDegreeOfConcurrency, IEnumerable<T> collection, Func<T, Task> taskFactory)
{
    var activeTasks = new List<Task>(maxDegreeOfConcurrency);
    foreach (var task in collection.Select(taskFactory))
    {
        activeTasks.Add(task);
        if (activeTasks.Count == maxDegreeOfConcurrency)
        {
            await Task.WhenAny(activeTasks.ToArray());
            //observe exceptions here
            activeTasks.RemoveAll(t => t.IsCompleted); 
        }
    }
    await Task.WhenAll(activeTasks.ToArray()).ContinueWith(t => 
    {
        //observe exceptions in a manner consistent with the above   
    });
}

The ToArray() calls can be optimized by using an array instead of a list and replacing completed tasks, but I doubt it would make much of a difference in most scenarios. Sample usage per the OP's question:

RunWithMaxDegreeOfConcurrency(10, ids, async i =>
{
    ICustomerRepo repo = new CustomerRepo();
    var cust = await repo.GetCustomer(i);
    customers.Add(cust);
});

EDIT Fellow SO user and TPL wiz Eli Arbel pointed me to a related article from Stephen Toub. As usual, his implementation is both elegant and efficient:

public static Task ForEachAsync<T>(
      this IEnumerable<T> source, int dop, Func<T, Task> body) 
{ 
    return Task.WhenAll( 
        from partition in Partitioner.Create(source).GetPartitions(dop) 
        select Task.Run(async delegate { 
            using (partition) 
                while (partition.MoveNext()) 
                    await body(partition.Current).ContinueWith(t => 
                          {
                              //observe exceptions
                          });
                      
        })); 
}

Another solution I found (especially useful if you want to set a global behaviour) is to use the $.ajaxsetup() method together with the statusCode property. Like others pointed out, don't use a redirect statuscode (3xx), instead use a 4xx statuscode and handle the redirect client-side.

$.ajaxSetup({ 
  statusCode : {
    400 : function () {
      window.location = "/";
    }
  }
});

Replace 400 with the statuscode you want to handle. Like already mentioned 401 Unauthorized could be a good idea. I use the 400 since it's very unspecific and I can use the 401 for more specific cases (like wrong login credentials). So instead of redirecting directly your backend should return a 4xx error-code when the session timed out and you you handle the redirect client-side. Works perfect for me even with frameworks like backbone.js

Visual select the text, then U for uppercase or u for lowercase. To swap all casing in a visual selection, press ~ (tilde).

Without using a visual selection, gU<motion> will make the characters in motion uppercase, or use gu<motion> for lowercase.

For more of these, see Section 3 in Vim's change.txt help file.

real deal is:

docker volume create xdata
docker volume inspect xdata

so you see its mount poit dir.
just copy your stuff there
then

docker run  --name=example1 --mount source=xdata,destination=/xdata -it yessa bash

where yessa is image name

I just solved this problem very elegantly after a lot of trial and error.

Check out my blog post: http://geon.github.io/programming/2016/02/24/flexbox-full-page-web-app-layout

Basically, to make a flexbox cell scrollable, you have to make all its parents overflow: hidden;, or it will just ignore your overflow settings and make the parent larger instead.

There is a "variant" to pax' answer... ;-)

int i = -1;
for(String s : stringArray) {
    doSomethingWith(s, ++i);
}

Use percent-encoded form. Some (mainly old) computers running Windows XP for example do not support Unicode, but rather ISO encodings. That is the reason percent-encoded URLs were invented. Also, if you give a URL printed on paper to a user, containing characters that cannot be easily typed, that user may have a hard time typing it (or just ignore it). Percent-encoded form can even be used in many of the oldest machines that ever existed (although they don't support internet of course).

There is a downside though, as percent-encoded characters are longer than the original ones, thus possibly resulting in really long URLs. But just try to ignore it, or use a URL shortener (I would recommend goo.gl in this case, which makes a 13-character long URL). Also, if you don't want to register for a Google account, try bit.ly (bit.ly makes slightly longer URLs, with the length being 14 characters).

$this->db->where('(a = 1 or a = 2)');

Following the greenhoorn's answer, you can use "Extensions" like this:

  public static class HttpClientExtensions
    {
        public static HttpClient AddTokenToHeader(this HttpClient cl, string token)
        {
            //int timeoutSec = 90;
            //cl.Timeout = new TimeSpan(0, 0, timeoutSec);
            string contentType = "application/json";
            cl.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue(contentType));
            cl.DefaultRequestHeaders.Add("Authorization", String.Format("Bearer {0}", token));
            var userAgent = "d-fens HttpClient";
            cl.DefaultRequestHeaders.Add("User-Agent", userAgent);
            return cl;
        }
    }

And use:

string _tokenUpdated = "TOKEN";
HttpClient _client;
_client.AddTokenToHeader(_tokenUpdated).GetAsync("/api/values")

In my experience, I often encounter the following situations;

1. If you work in a corporate company, contact the network and security team. Because in requests made to external services, it may be necessary to give permission for the relevant endpoint.

2. Another issue is that the SSL certificate may have expired on the server where your application is running.

You can try this:

this.activatedRoute.paramMap.subscribe(x => {
    let id = x.get('id');
    console.log(id);  
});

The parameter -DskipTests may not work depending on your surefire-plugin version.

You can use "-Dmaven.test.skip.exec" instead of "-DskipTests"

Maybe you're pushing a new local branch?

A new local branch must be pushed explicitly:

git push origin your-new-branch-name

Just one of those things about git... You clone a repo, make a branch, commit some changes, push... "Everything is up to date". I understand why it happens, but this workflow is extremely unfriendly to newcomers.

Yes, you can use the shorthand syntax for if statements.

rate = lambda(t): (200 * exp(-t)) if t > 200 else (400 * exp(-t))

Note that you don't use explicit return statements inlambdas either.

Aman is correct that you can use normal matplotlib commands, but this is also built into the FacetGrid:

import seaborn as sns
planets = sns.load_dataset("planets")
g = sns.factorplot("year", data=planets, aspect=1.5, kind="count", color="b")
g.set_xticklabels(rotation=30)

There are some comments and another answer claiming this "doesn't work", however, anyone can run the code as written here and see that it does work. The other answer does not provide a reproducible example of what isn't working, making it very difficult to address, but my guess is that people are trying to apply this solution to the output of functions that return an Axes object instead of a Facet Grid. These are different things, and the Axes.set_xticklabels() method does indeed require a list of labels and cannot simply change the properties of the existing labels on the Axes. The lesson is that it's important to pay attention to what kind of objects you are working with.

When you already have an older version of NumPy, use this:

pip install numpy --upgrade

If it still doesn't work, try:

pip install numpy --upgrade --ignore-installed

The ZIP file format does allow to store the permission bits, but Windows programs normally ignore it. The zip utility on Cygwin however does preserve the x bit, just like it does on Linux. If you do not want to use Cygwin, you can take a source code and tweak it so that all *.sh files get the executable bit set. Or write a script like explained here

A duplicate in the database should be a 409 CONFLICT.

    bottom:0px;
    top:50px
}

For this lint warning, as for all other lint warnings, note that you can get a fuller explanation than just what is in the one line error message; you don't have to search the web for more info.

If you are using lint via Eclipse, either open the lint warnings view, where you can select the lint error and see a longer explanation, or invoke the quick fix (Ctrl-1) on the error line, and one of the suggestions is "Explain this issue", which will also pop up a fuller explanation. If you are not using Eclipse, you can generate an HTML report from lint (lint --html <filename>) which includes full explanations next to the warnings, or you can ask lint to explain a particular issue. For example, the issue related to allowBackup has the id AllowBackup (shown at the end of the error message), so the fuller explanation is:

$ ./lint --show AllowBackup
AllowBackup
-----------
Summary: Ensure that allowBackup is explicitly set in the application's
manifest

Priority: 3 / 10
Severity: Warning
Category: Security

The allowBackup attribute determines if an application's data can be backed up and restored, as documented here.

By default, this flag is set to true. When this flag is set to true, application data can be backed up and restored by the user using adb backup and adb restore.

This may have security consequences for an application. adb backup allows users who have enabled USB debugging to copy application data off of the device. Once backed up, all application data can be read by the user. adb restore allows creation of application data from a source specified by the user. Following a restore, applications should not assume that the data, file permissions, and directory permissions were created by the application itself.

Setting allowBackup="false" opts an application out of both backup and restore.

To fix this warning, decide whether your application should support backup and explicitly set android:allowBackup=(true|false)

Along with the other answers mentioned by Barmar and Joni, I've noticed that I sometimes have to leave a blank line before and after my EOF when using <<-EOF.

There is a simple method which you could use with html class attribute and shorthand if/else. No need to make it so complex. Just use following method.

<div class="{{expression == true ? 'class_if_expression_true' : 'class_if_expression_false' }}">Your Content</div>

Jonas's answer does not change the font size of the axes. Sergeyf's answer does not work when there are multiple subplots.

Here is a modification of their answers that works for me when I have multiple subplots:

set(findall(gcf,'type','axes'),'fontsize',30)
set(findall(gcf,'type','text'),'fontSize',30) 

Find out which other service uses port 80.

I have heard skype uses port 80. Check it there isn't another server or database running in the background on port 80.

Two good alternatives to xampp are wamp and easyphp. Out of that, wamp is the most user friendly and it also has a built in tool for checking if port 80 is in use and which service is currently using it.

Or disable iis. It has been known to use port 80 by default.

typeof(BaseClass).IsAssignableFrom(unknownType);

Use:

s.erase(std::remove_if(s.begin(), s.end(), my_predicate), s.end());

bool my_predicate(char c)
{
 return !(isalpha(c) || c=='_' || c==' '); // depending on you definition of special characters
}

And you'll get a clean string s.

erase() will strip it of all the special characters and is highly customisable with the my_predicate() function.

An improved version for using bitmask to handle 256 chars:

public static void removeDuplicates3(char[] str) 
{
  long map[] = new long[] {0, 0, 0 ,0};
  long one = 1;

  for (int i = 0; i < str.length; i++) 
  {
    long chBit = (one << (str[i]%64));
    int n = (int) str[i]/64;

    if ((map[n] & chBit ) > 0) // duplicate detected
        str[i] = 0;
    else // add unique char as a bit '1' to the map
        map[n] |= chBit ;
  }

  // get rid of those '\0's
  int wi = 1;
  for (int i=1; i<str.length; i++)
  {
    if (str[i]!=0) str[wi++] = str[i];
  }

  // setting the rest as '\0'
  for (;wi<str.length; wi++) str[wi] = 0;
}

Result: "##1!!ASDJasanwAaw.,;..][,[]==--0" ==> "#1!ASDJasnw.,;][=-0" (double quotes not included)

Here's one way:

cout << '\a';

From C++ Character Constants:

Alert: \a

You can open the Windows event viewer to try to get more information about the errors : in the "Application" section of the Windows logs, there is a good chance you will find error messages from Apache. (At least I found what was wrong in my case there !)

pip install str2bool

>>> from str2bool import str2bool
>>> str2bool('Yes')
True
>>> str2bool('FaLsE')
False

Check that :

• Apache can physically access the file (the user that run apache, probably www-data or apache, can access the file in the filesystem)
• Apache can list the content of the folder (read permission)
• Apache has a "Allow" directive for that folder. There should be one for /var/www/, you can check default vhost for example.

Additionally, you can look at the error.log file (usually located at /var/log/apache2/error.log) which will describe why you get the 403 error exactly.

Finally, you may want to restart apache, just to be sure all that configuration is applied. This can be generally done with /etc/init.d/apache2 restart. On some system, the script will be called httpd. Just figure out.

Not so hard:

#include <thread>

void Test::runMultiThread()
{
    std::thread t1(&Test::calculate, this,  0, 10);
    std::thread t2(&Test::calculate, this, 11, 20);
    t1.join();
    t2.join();
}

If the result of the computation is still needed, use a future instead:

#include <future>

void Test::runMultiThread()
{
     auto f1 = std::async(&Test::calculate, this,  0, 10);
     auto f2 = std::async(&Test::calculate, this, 11, 20);

     auto res1 = f1.get();
     auto res2 = f2.get();
}

Python Classes

class name:
    def __init__(self, name):
        self.name = name
        print("name: "+name)

Somewhere else:

john = name("john")

Output:
name: john

"getops" and "getopt" are very limited. While "getopt" is suggested not to be used at all, it does offer long options. Where as "getopts" does only allow single character options such as "-a" "-b". There are a few more disadvantages when using either one.

So i've written a small script that replaces "getopts" and "getopt". It's a start, it could probably be improved a lot.

Update 08-04-2020: I've added support for hyphens e.g. "--package-name".

Usage: "./script.sh package install --package "name with space" --build --archive"

# Example:
# parseArguments "${@}"
# echo "${ARG_0}" -> package
# echo "${ARG_1}" -> install
# echo "${ARG_PACKAGE}" -> "name with space"
# echo "${ARG_BUILD}" -> 1 (true)
# echo "${ARG_ARCHIVE}" -> 1 (true)
function parseArguments() {
  PREVIOUS_ITEM=''
  COUNT=0
  for CURRENT_ITEM in "${@}"
  do
    if [[ ${CURRENT_ITEM} == "--"* ]]; then
      printf -v "ARG_$(formatArgument "${CURRENT_ITEM}")" "%s" "1" # could set this to empty string and check with [ -z "${ARG_ITEM-x}" ] if it's set, but empty.
    else
      if [[ $PREVIOUS_ITEM == "--"* ]]; then
        printf -v "ARG_$(formatArgument "${PREVIOUS_ITEM}")" "%s" "${CURRENT_ITEM}"
      else
        printf -v "ARG_${COUNT}" "%s" "${CURRENT_ITEM}"
      fi
    fi

    PREVIOUS_ITEM="${CURRENT_ITEM}"
    (( COUNT++ ))
  done
}

# Format argument.
function formatArgument() {
  ARGUMENT="${1^^}" # Capitalize.
  ARGUMENT="${ARGUMENT/--/}" # Remove "--".
  ARGUMENT="${ARGUMENT//-/_}" # Replace "-" with "_".
  echo "${ARGUMENT}"
}

I looked at existing answers but I also found that setting the button frame is an important first step.

Here is a function that I use that takes care of this:

const CGFloat kImageTopOffset   = -15;
const CGFloat kTextBottomOffset = -25;

+ (void) centerButtonImageTopAndTextBottom: (UIButton*)         button 
                                     frame: (CGRect)            buttonFrame
                                      text: (NSString*)         textString
                                 textColor: (UIColor*)          textColor
                                      font: (UIFont*)           textFont
                                     image: (UIImage*)          image
                                  forState: (UIControlState)    buttonState
{
    button.frame = buttonFrame;

    [button setTitleColor: (UIColor*)       textColor
                 forState: (UIControlState) buttonState];

    [button setTitle: (NSString*) textString
            forState: (UIControlState) buttonState ];


    [button.titleLabel setFont: (UIFont*) textFont ];

    [button setTitleEdgeInsets: UIEdgeInsetsMake( 0.0, -image.size.width, kTextBottomOffset,  0.0)]; 

    [button setImage: (UIImage*)       image 
            forState: (UIControlState) buttonState ];

    [button setImageEdgeInsets: UIEdgeInsetsMake( kImageTopOffset, 0.0, 0.0,- button.titleLabel.bounds.size.width)];
}

I hit this same issue trying to install Dashcast on Centos 7. The fix was adding -fPIC at the end of each of the CFLAGS in the x264 Makefile. Then I had to run make distclean for both x264 and ffmpeg and rebuild.

I like the following approach as it works for all situations:

$(':focus').blur();

Accessing package variables in a Script Component (of a Data Flow Task) is not the same as accessing package variables in a Script Task. For a Script Component, you first need to open the Script Transformation Editor (right-click on the component and select "Edit..."). In the Custom Properties section of the Script tab, you can enter (or select) the properties you want to make available to the script, either on a read-only or read-write basis: Then, within the script itself, the variables will be available as strongly-typed properties of the Variables object:

// Modify as necessary
public override void PreExecute()
{
    base.PreExecute();
    string thePath = Variables.FilePath;
    // Do something ...
}

public override void PostExecute()
{
    base.PostExecute();
    string theNewValue = "";
    // Do something to figure out the new value...
    Variables.FilePath = theNewValue;
}

public override void Input0_ProcessInputRow(Input0Buffer Row)
{
    string thePath = Variables.FilePath;
    // Do whatever needs doing here ...
}

One important caveat: if you need to write to a package variable, you can only do so in the PostExecute() method.

Regarding the code snippet:

IDTSVariables100 varCollection = null;
this.VariableDispenser.LockForRead("User::FilePath");
string XlsFile;

XlsFile = varCollection["User::FilePath"].Value.ToString();

varCollection is initialized to null and never set to a valid value. Thus, any attempt to dereference it will fail.

this error basically comes when you use the object before using it.

Simple solution for downloading a file from the server:

protected void btnDownload_Click(object sender, EventArgs e)
        {
            string FileName = "Durgesh.jpg"; // It's a file name displayed on downloaded file on client side.

            System.Web.HttpResponse response = System.Web.HttpContext.Current.Response;
            response.ClearContent();
            response.Clear();
            response.ContentType = "image/jpeg";
            response.AddHeader("Content-Disposition", "attachment; filename=" + FileName + ";");
            response.TransmitFile(Server.MapPath("~/File/001.jpg"));
            response.Flush();
            response.End();
        }

some thing as follows ::

Add this After the body tag

This is a rough sketch, you will need to modify it according to your needs.

<script>
var f = document.createElement("form");
f.setAttribute('method',"post");
f.setAttribute('action',"submit.php");

var i = document.createElement("input"); //input element, text
i.setAttribute('type',"text");
i.setAttribute('name',"username");

var s = document.createElement("input"); //input element, Submit button
s.setAttribute('type',"submit");
s.setAttribute('value',"Submit");

f.appendChild(i);
f.appendChild(s);

//and some more input elements here
//and dont forget to add a submit button

document.getElementsByTagName('body')[0].appendChild(f);

</script>

while read CMD; do
    echo $CMD

task scheduler : powershell.exe -noexit & .\your_script.ps1

be sure to put your script in this folder : windows\system32

good luck !

I believe Quassnoi has answered your direct question. Just a side note: Maybe this is just some awkward wording on your part, but you seem to be under the impression that you have three primary keys, one on each field. This is not the case. By definition, you can only have one primary key. What you have here is a primary key that is a composite of three fields. Thus, you cannot "drop the primary key on a column". You can drop the primary key, or not drop the primary key. If you want a primary key that only includes one column, you can drop the existing primary key on 3 columns and create a new primary key on 1 column.

You can do something like

for(var k in result) {
   console.log(k, result[k]);
}

which loops over all the keys in the returned json and prints the values. However, if you have a nested structure, you will need to use

typeof result[k] === "object"

to determine if you have to loop over the nested objects. Most APIs I have used, the developers know the structure of what is being returned, so this is unnecessary. However, I suppose it's possible that this expectation is not good for all cases.

Clearly set.intersection is what you want here, but in case you ever need a generalisation of "take the sum of all these", "take the product of all these", "take the xor of all these", what you are looking for is the reduce function:

from operator import and_
from functools import reduce
print(reduce(and_, [{1,2,3},{2,3,4},{3,4,5}])) # = {3}

or

print(reduce((lambda x,y: x&y), [{1,2,3},{2,3,4},{3,4,5}])) # = {3}
