If you are looking for a modern >1.7 Dojo way of destroying all node's children this is the way:

// Destroys all domNode's children nodes
// domNode can be a node or its id:
domConstruct.empty(domNode);

Safely empty the contents of a DOM element. empty() deletes all children but keeps the node there.

Check "dom-construct" documentation for more details.

// Destroys domNode and all it's children
domConstruct.destroy(domNode);

Destroys a DOM element. destroy() deletes all children and the node itself.

Try this. It is not watertight¹, but it might be good enough:

function addhttp($url) {
    if (!preg_match("@^[hf]tt?ps?://@", $url)) {
        $url = "http://" . $url;
    }
    return $url;
}

_{1. That is, prefixes like "fttps://" are treated as valid.}

Newer JDK distributions ship with JConsole and VisualVM. Both are fantastic tools for getting the dirty details from a running Java process. If you have to do this programmatically, investigate JMX.

As previous answers have solved for, but should be stated very explicitly: the php code needs to live in the php-fpm container, while the static files need to live in the nginx container. For simplicity, most people have just attached all the code to both, as I have also done below. If the future, I will likely separate out these different parts of the code in my own projects as to minimize which containers have access to which parts.

Updated my example files below with this latest revelation (thank you @alkaline )

This seems to be the minimum setup for docker 2.0 forward (because things got a lot easier in docker 2.0)

docker-compose.yml:

version: '2'
services:
  php:
    container_name: test-php
    image: php:fpm
    volumes:
      - ./code:/var/www/html/site
  nginx:
    container_name: test-nginx
    image: nginx:latest
    volumes:
      - ./code:/var/www/html/site
      - ./site.conf:/etc/nginx/conf.d/site.conf:ro
    ports:
      - 80:80

(UPDATED the docker-compose.yml above: For sites that have css, javascript, static files, etc, you will need those files accessible to the nginx container. While still having all the php code accessible to the fpm container. Again, because my base code is a messy mix of css, js, and php, this example just attaches all the code to both containers)

In the same folder:

site.conf:

server
{
    listen   80;
    server_name site.local.[YOUR URL].com;

    root /var/www/html/site;
    index index.php;

    location /
    {
        try_files $uri =404;
    }

    location ~ \.php$ {
        fastcgi_pass   test-php:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }
}

In folder code:

./code/index.php:

<?php
phpinfo();

and don't forget to update your hosts file:

127.0.0.1 site.local.[YOUR URL].com

and run your docker-compose up

$docker-compose up -d

and try the URL from your favorite browser

site.local.[YOUR URL].com/index.php

I had this problem too, and I found that I just need to restart zookeeper, then restart tomcat so my webapp connected nicely then

But we can declare a function inside main():

int main()
{
    void a();
}

Although the syntax is correct, sometimes it can lead to the "Most vexing parse":

#include <iostream>


struct U
{
    U() : val(0) {}
    U(int val) : val(val) {}

    int val;
};

struct V
{
    V(U a, U b)
    {
        std::cout << "V(" << a.val << ", " << b.val << ");\n";
    }
    ~V()
    {
        std::cout << "~V();\n";
    }
};

int main()
{
    int five = 5;
    V v(U(five), U());
}

=> no program output.

(Only Clang warning after compilation).

C++'s most vexing parse again

It's used to add padding in UIScrollView

Without contentInset, a table view is like this:

Then set contentInset:

tableView.contentInset = UIEdgeInsets(top: 20, left: 0, bottom: 0, right: 0)

The effect is as below:

Seems to be better, right?

And I write a blog to study the contentInset, criticism is welcome.

Based on Jakub's answer you can configure the following git aliases for convenience:

accept-ours = "!f() { git checkout --ours -- \"${@:-.}\"; git add -u \"${@:-.}\"; }; f"
accept-theirs = "!f() { git checkout --theirs -- \"${@:-.}\"; git add -u \"${@:-.}\"; }; f"

They optionally take one or several paths of files to resolve and default to resolving everything under the current directory if none are given.

Add them to the [alias] section of your ~/.gitconfig or run

git config --global alias.accept-ours '!f() { git checkout --ours -- "${@:-.}"; git add -u "${@:-.}"; }; f'
git config --global alias.accept-theirs '!f() { git checkout --theirs -- "${@:-.}"; git add -u "${@:-.}"; }; f'

final indicates that the value of the variable won't change - in other words, a constant whose value can't be modified after it is declared.

Use public final static String when you want to create a String that:

1. belongs to the class (static: no instance necessary to use it), and that
2. won't change (final), for instance when you want to define a String constant that will be available to all instances of the class, and to other objects using the class.

Example:

public final static String MY_CONSTANT = "SomeValue";

// ... in some other code, possibly in another object, use the constant:
if (input.equals(MyClass.MY_CONSTANT)

Similarly:

public static final int ERROR_CODE = 127;

It isn't required to use final, but it keeps a constant from being changed inadvertently during program execution, and serves as an indicator that the variable is a constant.

Even if the constant will only be used - read - in the current class and/or in only one place, it's good practice to declare all constants as final: it's clearer, and during the lifetime of the code the constant may end up being used in more than one place.

Furthermore using final may allow the implementation to perform some optimization, e.g. by inlining an actual value where the constant is used.

The pom.xml is going to look at your local repository to try and find the dependency that matches your artifact. Also you shouldn't really be using the system scope or systemPath attributes, these are normally reserved for things that are in the JDK and not the JRE

See this question for how to install maven artifacts.

Ar you looking for that:

isEmptyObject(obj) {
  return (obj && (Object.keys(obj).length === 0));
}

(found here)

or that :

function isEmpty(obj) {
    for(var key in obj) {
        if(obj.hasOwnProperty(key))
            return false;
    }
    return true;
}

It's a good idea to apply a recursive definition, as in Vadim Smolyakov's answer, combined with a DP (dynamic programming), but for the latter you may apply the lru_cache decorator from module functools:

import functools

@functools.lru_cache(maxsize = None)
def binom(n,k):
    if k == 0: return 1
    if n == k: return 1
    return binom(n-1,k-1)+binom(n-1,k)

I just check if object is null , it works 100% for me

    try
    {
        var ID = Convert.ToInt32(Request.Params["ID"]);
        var Cert = (from cert in db.TblCompCertUploads where cert.CertID == ID select cert).FirstOrDefault();
        if (Cert != null)
        {
            db.TblCompCertUploads.DeleteObject(Cert);
            db.SaveChanges();
            ViewBag.Msg = "Deleted Successfully";
        }
        else
        {
            ViewBag.Msg = "Not Found !!";
        }                           
    }
    catch
    {
        ViewBag.Msg = "Something Went wrong";
    }

One gotcha which caught me out:

[repos:/path/to/dir/] # this won't work

but

[repos:/path/to/dir]  # this is right

You need to not include a trailing slash on the directory, or you'll see 403 for the OPTIONS request.

In c#, This can bypass changing protected zone settings.

var options = new InternetExplorerOptions();
options.IntroduceInstabilityByIgnoringProtectedModeSettings = true;
options.ElementScrollBehavior = InternetExplorerElementScrollBehavior.Bottom;

First you need to determine the revision ID of the last known commit. You can use HEAD^ or HEAD~{1} if you know you need to reverse exactly one commit.

git reset --hard <revision_id_of_last_known_good_commit>
git push --force

Please consider long and hard if you can't get around implementing your own cryptography

The ugly truth of the matter is that if you are asking this question you will probably not be able to design and implement a secure system.

Let me illustrate my point: Imagine you are building a web application and you need to store some session data. You could assign each user a session ID and store the session data on the server in a hash map mapping session ID to session data. But then you have to deal with this pesky state on the server and if at some point you need more than one server things will get messy. So instead you have the idea to store the session data in a cookie on the client side. You will encrypt it of course so the user cannot read and manipulate the data. So what mode should you use? Coming here you read the top answer (sorry for singling you out myforwik). The first one covered - ECB - is not for you, you want to encrypt more than one block, the next one - CBC - sounds good and you don't need the parallelism of CTR, you don't need random access, so no XTS and patents are a PITA, so no OCB. Using your crypto library you realize that you need some padding because you can only encrypt multiples of the block size. You choose PKCS7 because it was defined in some serious cryptography standards. After reading somewhere that CBC is provably secure if used with a random IV and a secure block cipher, you rest at ease even though you are storing your sensitive data on the client side.

Years later after your service has indeed grown to significant size, an IT security specialist contacts you in a responsible disclosure. She's telling you that she can decrypt all your cookies using a padding oracle attack, because your code produces an error page if the padding is somehow broken.

This is not a hypothetical scenario: Microsoft had this exact flaw in ASP.NET until a few years ago.

The problem is there are a lot of pitfalls regarding cryptography and it is extremely easy to build a system that looks secure for the layman but is trivial to break for a knowledgeable attacker.

What to do if you need to encrypt data

For live connections use TLS (be sure to check the hostname of the certificate and the issuer chain). If you can't use TLS, look for the highest level API your system has to offer for your task and be sure you understand the guarantees it offers and more important what it does not guarantee. For the example above a framework like Play offers client side storage facilities, it does not invalidate the stored data after some time, though, and if you changed the client side state, an attacker can restore a previous state without you noticing.

If there is no high level abstraction available use a high level crypto library. A prominent example is NaCl and a portable implementation with many language bindings is Sodium. Using such a library you do not have to care about encryption modes etc. but you have to be even more careful about the usage details than with a higher level abstraction, like never using a nonce twice. For custom protocol building (say you want something like TLS, but not over TCP or UDP) there are frameworks like Noise and associated implementations that do most of the heavy lifting for you, but their flexibility also means there is a lot of room for error, if you don't understand in depth what all the components do.

If for some reason you cannot use a high level crypto library, for example because you need to interact with existing system in a specific way, there is no way around educating yourself thoroughly. I recommend reading Cryptography Engineering by Ferguson, Kohno and Schneier. Please don't fool yourself into believing you can build a secure system without the necessary background. Cryptography is extremely subtle and it's nigh impossible to test the security of a system.

Comparison of the modes

Encryption only:

• Modes that require padding: Like in the example, padding can generally be dangerous because it opens up the possibility of padding oracle attacks. The easiest defense is to authenticate every message before decryption. See below.
  • ECB encrypts each block of data independently and the same plaintext block will result in the same ciphertext block. Take a look at the ECB encrypted Tux image on the ECB Wikipedia page to see why this is a serious problem. I don't know of any use case where ECB would be acceptable.
  • CBC has an IV and thus needs randomness every time a message is encrypted, changing a part of the message requires re-encrypting everything after the change, transmission errors in one ciphertext block completely destroy the plaintext and change the decryption of the next block, decryption can be parallelized / encryption can't, the plaintext is malleable to a certain degree - this can be a problem.
• Stream cipher modes: These modes generate a pseudo random stream of data that may or may not depend the plaintext. Similarly to stream ciphers generally, the generated pseudo random stream is XORed with the plaintext to generate the ciphertext. As you can use as many bits of the random stream as you like you don't need padding at all. Disadvantage of this simplicity is that the encryption is completely malleable, meaning that the decryption can be changed by an attacker in any way he likes as for a plaintext p1, a ciphertext c1 and a pseudo random stream r and attacker can choose a difference d such that the decryption of a ciphertext c2=c1?d is p2 = p1?d, as p2 = c2?r = (c1 ? d) ? r = d ? (c1 ? r). Also the same pseudo random stream must never be used twice as for two ciphertexts c1=p1?r and c2=p2?r, an attacker can compute the xor of the two plaintexts as c1?c2=p1?r?p2?r=p1?p2. That also means that changing the message requires complete reencryption, if the original message could have been obtained by an attacker. All of the following steam cipher modes only need the encryption operation of the block cipher, so depending on the cipher this might save some (silicon or machine code) space in extremely constricted environments.
  • CTR is simple, it creates a pseudo random stream that is independent of the plaintext, different pseudo random streams are obtained by counting up from different nonces/IVs which are multiplied by a maximum message length so that overlap is prevented, using nonces message encryption is possible without per message randomness, decryption and encryption are completed parallelizable, transmission errors only effect the wrong bits and nothing more
  • OFB also creates a pseudo random stream independent of the plaintext, different pseudo random streams are obtained by starting with a different nonce or random IV for every message, neither encryption nor decryption is parallelizable, as with CTR using nonces message encryption is possible without per message randomness, as with CTR transmission errors only effect the wrong bits and nothing more
  • CFB's pseudo random stream depends on the plaintext, a different nonce or random IV is needed for every message, like with CTR and OFB using nonces message encryption is possible without per message randomness, decryption is parallelizable / encryption is not, transmission errors completely destroy the following block, but only effect the wrong bits in the current block
• Disk encryption modes: These modes are specialized to encrypt data below the file system abstraction. For efficiency reasons changing some data on the disc must only require the rewrite of at most one disc block (512 bytes or 4kib). They are out of scope of this answer as they have vastly different usage scenarios than the other. Don't use them for anything except block level disc encryption. Some members: XEX, XTS, LRW.

Authenticated encryption:

To prevent padding oracle attacks and changes to the ciphertext, one can compute a message authentication code (MAC) on the ciphertext and only decrypt it if it has not been tampered with. This is called encrypt-then-mac and should be preferred to any other order. Except for very few use cases authenticity is as important as confidentiality (the latter of which is the aim of encryption). Authenticated encryption schemes (with associated data (AEAD)) combine the two part process of encryption and authentication into one block cipher mode that also produces an authentication tag in the process. In most cases this results in speed improvement.

• CCM is a simple combination of CTR mode and a CBC-MAC. Using two block cipher encryptions per block it is very slow.
• OCB is faster but encumbered by patents. For free (as in freedom) or non-military software the patent holder has granted a free license, though.
• GCM is a very fast but arguably complex combination of CTR mode and GHASH, a MAC over the Galois field with 2^128 elements. Its wide use in important network standards like TLS 1.2 is reflected by a special instruction Intel has introduced to speed up the calculation of GHASH.

Recommendation:

Considering the importance of authentication I would recommend the following two block cipher modes for most use cases (except for disk encryption purposes): If the data is authenticated by an asymmetric signature use CBC, otherwise use GCM.

I found the above answer giving an error with Oracle SQL, you also must use square brackets, below;

SQL> SELECT Q'[Paddy O'Reilly]' FROM DUAL;

Result: Paddy O'Reilly

I found following program works for me

test1.sh 
a=xxx
test2.sh $a

in test2.sh you use $1 to refer variable a in test1.sh

echo $1

The output would be xxx

Use of the argmin method for numpy arrays.

import numpy as np
np.argmin(myList)

However, it is not the fastest method: it is 3 times slower than OP's answer on my computer. It may be the most concise one though.

Yet another initiative and recursive solution. The idea is to select a letter as a pivot and then create a word.

# for a string with length n, there is a factorial n! permutations
alphabet = 'abc'
starting_perm = ''
# with recursion
def premuate(perm, alphabet):
    if not alphabet: # we created one word by using all letters in the alphabet
        print(perm + alphabet)
    else:
        for i in range(len(alphabet)): # iterate over all letters in the alphabet
            premuate(perm + alphabet[i], alphabet[0:i] + alphabet[i+1:]) # chose one letter from the alphabet

# call it            
premuate(starting_perm, alphabet)

Output:

abc
acb
bac
bca
cab
cba

Numpy is required by pandas (and by virtually all numerical tools for Python). Scipy is not strictly required for pandas but is listed as an "optional dependency". I wouldn't say that pandas is an alternative to Numpy and/or Scipy. Rather, it's an extra tool that provides a more streamlined way of working with numerical and tabular data in Python. You can use pandas data structures but freely draw on Numpy and Scipy functions to manipulate them.

I've adopted Crazy Yoghurt's answer to swift's extensions.

extension UILabel {

    func boldRange(_ range: Range<String.Index>) {
        if let text = self.attributedText {
            let attr = NSMutableAttributedString(attributedString: text)
            let start = text.string.characters.distance(from: text.string.startIndex, to: range.lowerBound)
            let length = text.string.characters.distance(from: range.lowerBound, to: range.upperBound)
            attr.addAttributes([NSFontAttributeName: UIFont.boldSystemFont(ofSize: self.font.pointSize)], range: NSMakeRange(start, length))
            self.attributedText = attr
        }
    }

    func boldSubstring(_ substr: String) {
        if let text = self.attributedText {
            var range = text.string.range(of: substr)
            let attr = NSMutableAttributedString(attributedString: text)
            while range != nil {
                let start = text.string.characters.distance(from: text.string.startIndex, to: range!.lowerBound)
                let length = text.string.characters.distance(from: range!.lowerBound, to: range!.upperBound)
                var nsRange = NSMakeRange(start, length)
                let font = attr.attribute(NSFontAttributeName, at: start, effectiveRange: &nsRange) as! UIFont
                if !font.fontDescriptor.symbolicTraits.contains(.traitBold) {
                    break
                }
                range = text.string.range(of: substr, options: NSString.CompareOptions.literal, range: range!.upperBound..<text.string.endIndex, locale: nil)
            }
            if let r = range {
                boldRange(r)
            }
        }
    }
}

May be there is not good conversion between Range and NSRange, but I didn't found something better.

You can only select columns that are in the group or used in an aggregate function. You can use a join to get this working

select s1.* 
from sensorTable s1
inner join 
(
  SELECT sensorID, max(timestamp) as mts
  FROM sensorTable 
  GROUP BY sensorID 
) s2 on s2.sensorID = s1.sensorID and s1.timestamp = s2.mts

I guess the best way to do this is like this :

1. Store all your changes in a separate branch.
2. Then do a hard reset on the local master.
3. Then merge back your changes from the locally created branch
4. Then commit and push your changes.

That how I resolve mine, whenever it happens.

Obs.: Changing http.postBuffer might also require to set up the Nginx configuration file for gitlab to accept larger body sizes for the client, by tuning the value of client_max_body_size.

However, there is a workaround if you have access to the Gitlab machine or to a machine in its network, and that is by making use of git bundle.

1. go to your git repository on the source machine
2. run git bundle create my-repo.bundle --all
3. transfer (eg., with rsync) the my-repo.bundle file to the destination machine
4. on the destination machine, run git clone my-repo.bundle
5. git remote set-url origin "path/to/your/repo.git"
6. git push

All the best!

var div = getElementsByTagName('div')[0]; /* first div found; you can use getElementById for more specific element */
div.onclick = null; // OR:
div.onclick = function(){};

//edit

I didn't knew what method are you using for attaching events. For addEventListener you can use this:

div.removeEventListener('click',functionName,false); // functionName is the name of your callback function

Float them both the same way and add the margin of 40px. If you have 2 elements floating opposite ways you will have much less control and the containing element will determine how far apart they are.

#left{
    float: left;
    margin-right: 40px;
}
#right{
   float: left;
}

I would suggest not to create general debug and release tasks if the project is really something that gets compiled and so results in files. You should go with file-tasks which is quite doable in your example, as you state, that your output goes into different directories. Say your project just compiles a test.c file to out/debug/test.out and out/release/test.out with gcc you could setup your project like this:

WAYS = ['debug', 'release']
FLAGS = {}
FLAGS['debug'] = '-g'
FLAGS['release'] = '-O'
def out_dir(way)
  File.join('out', way)
end
def out_file(way)
  File.join(out_dir(way), 'test.out')
end
WAYS.each do |way|
  desc "create output directory for #{way}"
  directory out_dir(way)

  desc "build in the #{way}-way"
  file out_file(way) => [out_dir(way), 'test.c'] do |t|
    sh "gcc #{FLAGS[way]} -c test.c -o #{t.name}"
  end
end
desc 'build all ways'
task :all => WAYS.map{|way|out_file(way)}

task :default => [:all]

This setup can be used like:

rake all # (builds debug and release)
rake debug # (builds only debug)
rake release # (builds only release)

This does a little more as asked for, but shows my points:

1. output directories are created, as necessary.
2. the files are only recompiled if needed (this example is only correct for the simplest of test.c files).
3. you have all tasks readily at hand if you want to trigger the release build or the debug build.
4. this example includes a way to also define small differences between debug and release-builds.
5. no need to reenable a build-task that is parametrized with a global variable, because now the different builds have different tasks. the codereuse of the build-task is done by reusing the code to define the build-tasks. see how the loop does not execute the same task twice, but instead created tasks, that can later be triggered (either by the all-task or be choosing one of them on the rake commandline).

This error will also occur if you call .ps1 file from a .bat file and file path has spaces.

The fix is to make sure there are no spaces in the path of .ps1 file.

You can use substr_compare function to check start-with and ends-with:

function startsWith($haystack, $needle) {
    return substr_compare($haystack, $needle, 0, strlen($needle)) === 0;
}
function endsWith($haystack, $needle) {
    return substr_compare($haystack, $needle, -strlen($needle)) === 0;
}

^{This should be one of the fastest solutions on PHP 7 (benchmark script). Tested against 8KB haystacks, various length needles and full, partial and no match cases. strncmp is a touch faster for starts-with but it cannot check ends-with.}

Unitialized variables check. Link 1 and 2 already seem to do this just fine, though.

I can't say I have used any of these intensively, though :)

1. You can iterate using the index access,

2. To avoid O(n^2) complexity you can use two indices, i - current testing index, j - index to store next item and at the end of the cycle new size of the vector.

code:

void erase(std::vector<int>& v, int num)
{
  size_t j = 0;
  for (size_t i = 0; i < v.size(); ++i) {
    if (v[i] != num) v[j++] = v[i];
  }
  // trim vector to new size
  v.resize(j);
}

In such case you have no invalidating of iterators, complexity is O(n), and code is very concise and you don't need to write some helper classes, although in some case using helper classes can benefit in more flexible code.

This code does not use erase method, but solves your task.

Using pure stl you can do this in the following way (this is similar to the Motti's answer):

#include <algorithm>

void erase(std::vector<int>& v, int num) {
    vector<int>::iterator it = remove(v.begin(), v.end(), num);
    v.erase(it, v.end());
}

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

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

Source: Import page on mozilla (See Browser compatibility)

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

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

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

import * from "./mylib.js"

For more examples, this blog post is good.

Or maybe just use conditional chains with ternary operator. if … else if … else if … else chain.

I like this aproach better.

Just to clarify, there is a big difference between these two actions, as suggested by Jean-François Corbett.

One action is to copy / load the actual data FROM the Range("A2:A9") INTO a Variant Array called vArray (Changed to avoid confusion between Variant Array and Sheet both called Src):

vArray = Sheets("Src").Range("A2:A9").Value

while the other simply sets up a Range variable (SrcRange) with the ADDRESS of the range Sheets("Src").Range("A2:A9"):

Set SrcRange = Sheets("Src").Range("A2:A9")

In this case, the data is not copied, and remains where it is, but can now be accessed in much the same way as an Array. That is often perfectly adequate, but if you need to repeatedly access, test or calculate with that data, loading it into an Array first will be MUCH faster.

For example, say you want to check a "database" (large sheet) against a list of known Suburbs and Postcodes. Both sets of data are in separate sheets, but if you want it to run fast, load the suburbs and postcodes into an Array (lives in memory), then run through each line of the main database, testing against the array data. This will be much faster than if you access both from their original sheets.

This is more general than .NET and Windows. Managed is an environment where you have automatic memory management, garbage collection, type safety, ... unmanaged is everything else. So for example .NET is a managed environment and C/C++ is unmanaged.

Click on your project properties, go to the web section, from the Servers section, change from IIS express to Local IIS, it will create a virtual directory for you

In MyApplication, which extends Application:

public static Resources resources;

In MyApplication's onCreate:

resources = getResources();

Now you can use this field from anywhere in your application.

I write this answer because I was looking for a way to plot together the histograms of different groups. What follows is not very smart, but it works fine for me. I use Numpy to compute the histogram and Bokeh for plotting. I think it is self-explanatory, but feel free to ask for clarifications and I'll be happy to add details (and write it better).

figures = {
    'Transit': figure(title='Transit', x_axis_label='speed [km/h]', y_axis_label='frequency'),
    'Driving': figure(title='Driving', x_axis_label='speed [km/h]', y_axis_label='frequency')
}

cols = {'Vienna': 'red', 'Turin': 'blue', 'Rome': 'Orange'}
for gr in df_trips.groupby(['locality', 'means']):
    locality = gr[0][0]
    means = gr[0][1]
    fig = figures[means]
    h, b = np.histogram(pd.DataFrame(gr[1]).speed.values)
    fig.vbar(x=b[1:], top=h, width=(b[1]-b[0]), legend_label=locality, fill_color=cols[locality], alpha=0.5)

show(gridplot([
    [figures['Transit']],
    [figures['Driving']],
]))

My problem was that excel column was showing me "=concatenate(A1,B1)" instead of it 's value after concatenation.

I added a space after "," like this =concatenate(A1, B1) and it worked.

This is just an example that solved my problem.

Try and let me know if it works for you as well.

Sometimes it works without space as well, but at other times it doesn't.

It's actually not really clearly stated in the standard (RFC 3986) whether a percent-encoded version of . or .. is supposed to have the same this-folder/up-a-folder meaning as the unescaped version. Section 3.3 only talks about “The path segments . and ..”, without clarifying whether they match . and .. before or after pct-encoding.

Personally I find Firefox's interpretation that %2E does not mean . most practical, but unfortunately all the other browsers disagree. This would mean that you can't have a path component containing only . or ...

I think the only possible suggestion is “don't do that”! There are other path components that are troublesome too, typically due to server limitations: %2F, %00 and %5C sequences in paths may also be blocked by some web servers, and the empty path segment can also cause problems. So in general it's not possible to fit all possible byte sequences into a path component.

Make sure when executing Michael Krelin's solution you do the following

cat <your_public_key_file> >> ~/.ssh/authorized_keys

Note the double > without the double > the existing contents of authorized_keys will be over-written (nuked!) and that may not be desirable

ES2015 version

Array.prototype.diff = function(a) {return this.filter(i => a.indexOf(i) < 0)};

Array.prototype.union = function(a) {return [...this.diff(a), ...a]}

All objects in java are passed to functions by reference copy except primitives.

In effect, this means that you are sending a copy of the pointer to the original object rather than a copy of the object itself.

From Wikipedia,

The Card Security Code is located on the back of MasterCard, Visa and Discover credit or debit cards and is typically a separate group of 3 digits to the right of the signature strip. On American Express cards, the Card Security Code is a printed (NOT embossed) group of four digits on the front towards the right.

The Card Security Code (CSC), sometimes called Card Verification Value (CVV or CV2), Card Verification Value Code (CVVC), Card Verification Code (CVC), Verification Code (V-Code or V Code), or Card Code Verification (CCV)[1] is a security feature for credit or debit card transactions, giving increased protection against credit card fraud.

There are actually several types of security codes:

* The first code, called CVC1 or CVV1, is encoded on the magnetic stripe of the card and used for transactions in person.
* The second code, and the most cited, is CVV2 or CVC2. This CSC (also known as a CCID or Credit Card ID) is often asked for by merchants for them to secure "card not present" transactions occurring over the Internet, by mail, fax or over the phone. In many countries in Western Europe, due to increased attempts at card fraud, it is now mandatory to provide this code when the cardholder is not present in person.
* Contactless Card and Chip cards may supply their own codes generated electronically, such as iCVV or Dynamic CVV.

The CVC should not be confused with the standard card account number appearing in embossed or printed digits. (The standard card number undergoes a separate validation algorithm called the Luhn algorithm which serves to determine whether a given card's number is appropriate.)

The CVC should not be confused with PIN codes such as MasterCard SecureCode or Visa Verified by Visa. These codes are not printed or embedded in the card but are entered at the time of transaction using a keypad.

var depthead = (from s in db.M_Users
                  join m in db.M_User_Types on s.F_User_Type equals m.UserType_Id
                  where m.UserType_Name.ToUpper().Trim().Contains("DEPARTMENT HEAD")
                  select new {s.FullName,s.F_User_Type,s.userId,s.UserCode } 
               ).OrderBy(d => d.userId).ToList();

Model.AvailableDeptHead.Add(new SelectListItem { Text = "Select", Value = "0" });
for (int i = 0; i < depthead.Count; i++)
    Model.AvailableDeptHead.Add(new SelectListItem { Text = depthead[i].UserCode + " - " + depthead[i].FullName, Value = Convert.ToString(depthead[i].userId) });

Previously we were using something like that:

// Some form.
SetFieldReadOnly( () => Entity.UserName );
...
// Base form.
private void SetFieldReadOnly(Expression<Func<object>> property)
{
    var propName = GetPropNameFromExpr(property);
    SetFieldsReadOnly(propName);
}

private void SetFieldReadOnly(string propertyName)
{
    ...
}

Reason - compile time safety. No one can silently rename property and break code logic. Now we can use nameof().

You can use this attributes:

background-size: contain;
background-repeat: no-repeat;

and you code is then like this:

 <div style="text-align:center;background-image: url(/media/img_1_bg.jpg); background-size: contain;
background-repeat: no-repeat;" id="mainpage">

This should do it:

UPDATE TheTable
SET PhoneNumber = SUBSTRING(PhoneNumber, 1, 3) + '-' + 
                  SUBSTRING(PhoneNumber, 4, 3) + '-' + 
                  SUBSTRING(PhoneNumber, 7, 4)

Incorporated Kane's suggestion, you can compute the phone number's formatting at runtime. One possible approach would be to use scalar functions for this purpose (works in SQL Server):

CREATE FUNCTION FormatPhoneNumber(@phoneNumber VARCHAR(10))
RETURNS VARCHAR(12)
BEGIN
    RETURN SUBSTRING(@phoneNumber, 1, 3) + '-' + 
           SUBSTRING(@phoneNumber, 4, 3) + '-' + 
           SUBSTRING(@phoneNumber, 7, 4)
END

Following two steps worked perfectly fine for me:

1. Comment out the bind address from the file /etc/mysql/my.cnf:

   #bind-address = 127.0.0.1

2. Run following query in phpMyAdmin:

   GRANT ALL PRIVILEGES ON *.* TO 'root'@'%'; FLUSH PRIVILEGES;

use menu Project -> Build Settings ->

then remove armv7s from the"valid architectures". If standard has been chosen then delete that and then add armv7.

Given your URL:

http://locahost:8000/example?a=10

The best way that I have found to get the value for 'a' and display it on the page is to use the following:

{{ request()->get('a') }}

However, if you want to use it within an if statement, you could use:

@if( request()->get('a') )
    <script>console.log('hello')</script>
@endif

Hope that helps someone! :)

Having just kinda run into this problem myself, here's my solution (for both multiplication and addition):

static boolean wouldOverflowOccurwhenMultiplying(int a, int b) {
    // If either a or b are Integer.MIN_VALUE, then multiplying by anything other than 0 or 1 will result in overflow
    if (a == 0 || b == 0) {
        return false;
    } else if (a > 0 && b > 0) { // both positive, non zero
        return a > Integer.MAX_VALUE / b;
    } else if (b < 0 && a < 0) { // both negative, non zero
        return a < Integer.MAX_VALUE / b;
    } else { // exactly one of a,b is negative and one is positive, neither are zero
        if (b > 0) { // this last if statements protects against Integer.MIN_VALUE / -1, which in itself causes overflow.
            return a < Integer.MIN_VALUE / b;
        } else { // a > 0
            return b < Integer.MIN_VALUE / a;
        }
    }
}

boolean wouldOverflowOccurWhenAdding(int a, int b) {
    if (a > 0 && b > 0) {
        return a > Integer.MAX_VALUE - b;
    } else if (a < 0 && b < 0) {
        return a < Integer.MIN_VALUE - b;
    }
    return false;
}

feel free to correct if wrong or if can be simplified. I've done some testing with the multiplication method, mostly edge cases, but it could still be wrong.

The different names are just ways of packaging java apps.

Skinny – Contains ONLY the bits you literally type into your code editor, and NOTHING else.

Thin – Contains all of the above PLUS the app’s direct dependencies of your app (db drivers, utility libraries, etc).

Hollow – The inverse of Thin – Contains only the bits needed to run your app but does NOT contain the app itself. Basically a pre-packaged “app server” to which you can later deploy your app, in the same style as traditional Java EE app servers, but with important differences.

Fat/Uber – Contains the bit you literally write yourself PLUS the direct dependencies of your app PLUS the bits needed to run your app “on its own”.

Check out Refit for making calls to REST services from .NET. I've found it very easy to use:

Refit: The automatic type-safe REST library for .NET Core, Xamarin and .NET

Refit is a library heavily inspired by Square's Retrofit library, and it turns your REST API into a live interface:

public interface IGitHubApi {
        [Get("/users/{user}")]
        Task<User> GetUser(string user);
}

// The RestService class generates an implementation of IGitHubApi
// that uses HttpClient to make its calls:

var gitHubApi = RestService.For<IGitHubApi>("https://api.github.com");

var octocat = await gitHubApi.GetUser("octocat");

try document.querySelectorAll("#table td");

From rxjs 5.5 onwards, you can use the pipeable operators

import { map } from 'rxjs/operators';

What is wrong with the import 'rxjs/add/operator/map';

When we use this approach map operator will be patched to observable.prototype and becomes a part of this object.

If later on, you decide to remove map operator from the code that handles the observable stream but fail to remove the corresponding import statement, the code that implements map remains a part of the Observable.prototype.

When the bundlers tries to eliminate the unused code (a.k.a. tree shaking), they may decide to keep the code of the map operator in the Observable even though it’s not being used in the application.

Solution - Pipeable operators

Pipeable operators are pure functions and do not patch the Observable. You can import operators using the ES6 import syntax import { map } from "rxjs/operators" and then wrap them into a function pipe() that takes a variable number of parameters, i.e. chainable operators.

Something like this:

getHalls() {
    return this.http.get(HallService.PATH + 'hall.json')
    .pipe(
        map((res: Response) => res.json())
    );
}

try this (in CSS) for preventing line breaks in div texts:

white-space: nowrap;

I don't know of any built in method. But, coding by hand is not too difficult. Assuming the elements of the array you are dealing with are NSNumber objects of integer type, and 'arr' is the NSMutableArray that you want to reverse.

int n = [arr count];
for (int i=0; i<n/2; ++i) {
  id c  = [[arr objectAtIndex:i] retain];
  [arr replaceObjectAtIndex:i withObject:[arr objectAtIndex:n-i-1]];
  [arr replaceObjectAtIndex:n-i-1 withObject:c];
}

Since you start with a NSArray then you have to create the mutable array first with the contents of the original NSArray ('origArray').

NSMutableArray * arr = [[NSMutableArray alloc] init];
[arr setArray:origArray];

Edit: Fixed n -> n/2 in the loop count and changed NSNumber to the more generic id due to the suggestions in Brent's answer.

As alternative way you can go HERE - instruction how to install any required dll.

Or you can download NuGet and manage it from VS

the disabled attributes value is actally not considered.. usually if you have noticed the attribute is set as disabled="disabled" the "disabled" here is not necessary persay.. thus the best thing to do is to remove the attribute.

element.removeAttribute("disabled");     

also you could do

element.disabled=false;

Execute the following commands:

rm .git/refs/remotes/origin/master

git fetch

git branch --set-upstream-to=origin/master

Just in case, if you need to know what is .git/refs/remotes/origin/master, you would read the Remotes section in Git References.

Dim rows() AS DataRow = DataTable.Select("ColumnName1 = 'value3'")
If rows.Count > 0 Then
     searchedValue = rows(0).Item("ColumnName2") 
End If

With FirstOrDefault:

Dim row AS DataRow = DataTable.Select("ColumnName1 = 'value3'").FirstOrDefault()
If Not row Is Nothing Then
     searchedValue = row.Item("ColumnName2") 
End If

In C#:

var row = DataTable.Select("ColumnName1 = 'value3'").FirstOrDefault();
if (row != null)
     searchedValue = row["ColumnName2"];

I like the Except extension methods, but the original question doesn't have symmetric key access and I prefer Contains (or the Any variation) to join, so with all credit to azuneca's answer:

public static IEnumerable<T> Except<T, TKey>(this IEnumerable<TKey> items,
    IEnumerable<T> other, Func<T, TKey> getKey) {

    return from item in items
        where !other.Contains(getKey(item))
        select item;
}

Which can then be used like:

var filteredApps = unfilteredApps.Except(excludedAppIds, ua => ua.Id);

Also, this version allows for needing a mapping for the exception IEnumerable by using a Select:

var filteredApps = unfilteredApps.Except(excludedApps.Select(a => a.Id), ua => ua.Id);

This snippet works in IE7 at least

<!DOCTYPE html>
<html>
<head>
<meta charset=utf-8 />
<title>Test</title>
<style>
  #foo {
    position: fixed;

    right: 0;
  }
</style>
</head>
<body>
  <div id="foo">Hello World</div>
</body>
</html>

Nothing works from this tread. "forRoot" doesn't help.

Sorry. Sorted this out. I've managed to make it work by setting correct "routes" for this "forRoot" router setup routine

    import {RouterModule, Routes} from '@angular/router';    
    import {AppComponent} from './app.component';
    
    const appRoutes: Routes = [
      {path: 'UI/part1/Details', component: DetailsComponent}
    ];
    
    @NgModule({
      declarations: [
        AppComponent,
        DetailsComponent
      ],
      imports: [
        BrowserModule,
        HttpClientModule,
        RouterModule.forRoot(appRoutes)
      ],
      providers: [DetailsService],
      bootstrap: [AppComponent]
    })

Also may be helpful (spent some time to realize this) Optional route part:

    const appRoutes: Routes = [
       {path: 'UI/part1/Details', component: DetailsComponent},
       {path: ':project/UI/part1/Details', component: DetailsComponent}
    ];

Second rule allows to open URLs like
hostname/test/UI/part1/Details?id=666
and
hostname/UI/part1/Details?id=666

Been working as a frontend developer since 2012 but never stuck in a such over-complicated thing as angular2 (I have 3 years experience with enterprise level ExtJS)

It's in the standard library, and that's the most straight forward way I can see to implement such a function. So yes, just loop through the string and convert each character to lowercase.

Something trivial like this:

#include <ctype.h>

for(int i = 0; str[i]; i++){
  str[i] = tolower(str[i]);
}

or if you prefer one liners, then you can use this one by J.F. Sebastian:

for ( ; *p; ++p) *p = tolower(*p);

In powershell 5.1, I have a simple list_docker_image_tags.ps1 script like this:

[CmdletBinding()]
param (
    [Parameter(Mandatory = $true)]
    [string]
    $image
)

$url = "https://registry.hub.docker.com/v1/repositories/{0}/tags" -f $image 
Invoke-WebRequest $url  | ConvertFrom-Json | Write-Output

Then I can grep for 4.7 tags like this:

./list_docker_image_tags.ps1 microsoft/dotnet-framework | ?{ $_.name -match "4.7" }

Depending on what you need each child for (if you're looking to post it somewhere via AJAX) you can just do...

$("#formID").serialize()

It creates a string for you with all of the values automatically.

As for looping through objects, you can also do this.

$.each($("input, select, textarea"), function(i,v) {
    var theTag = v.tagName;
    var theElement = $(v);
    var theValue = theElement.val();
});

I was receiving the same error. You need to go increase the column length while importing the data for particular column. Choose a data source >> Advanced >> increase the column from default 50 to 200 or more.

It worked for me!

Assuming you're using winforms, default panel components does not offer you a way to disable the horizontal scrolling components. A workaround of this is to disable the auto scrolling and add a scrollbar yourself:

ScrollBar vScrollBar1 = new VScrollBar();
vScrollBar1.Dock = DockStyle.Right;
vScrollBar1.Scroll += (sender, e) => { panel1.VerticalScroll.Value = vScrollBar1.Value; };
panel1.Controls.Add(vScrollBar1);

Detailed discussion here.

Use this CSS (jsFiddle example):

input:disabled.btn:hover,
input:disabled.btn:active,
input:disabled.btn:focus {
  color: green
}

You have to write the most outer element on the left and the most inner element on the right.

.btn:hover input:disabled would select any disabled input elements contained in an element with a class btn which is currently hovered by the user.

I would prefer :disabled over [disabled], see this question for a discussion: Should I use CSS :disabled pseudo-class or [disabled] attribute selector or is it a matter of opinion?

By the way, Laravel (PHP) generates the HTML - not the browser.

I don't see a compelling reason to override onResume or onStart to set the width and height of the Window within DialogFragment's Dialog -- these particular lifecycle methods can get called repeatedly and unnecessarily execute that resizing code more than once due to things like multi window switching, backgrounding then foregrounding the app, and so on. The consequences of that repetition are fairly trivial, but why settle for that?

Setting the width/height instead within an overridden onActivityCreated() method will be an improvement because this method realistically only gets called once per instance of your DialogFragment. For example:

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);

    Window window = getDialog().getWindow();
    assert window != null;

    WindowManager.LayoutParams layoutParams = window.getAttributes();
    layoutParams.width = ViewGroup.LayoutParams.MATCH_PARENT;
    window.setAttributes(layoutParams);
}

Above I just set the width to be match_parent irrespective of device orientation. If you want your landscape dialog to not be so wide, you can do a check of whether getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT beforehand.

style="text-align:center;" 

(i think)

or you could just ignore it, it still works

You can use {} arround your variable, to separate it from what's after:

echo "{$test}y"

As reference, you can take a look to the Variable parsing - Complex (curly) syntax section of the PHP manual.

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

Try this:

a[id*='Some:Same'][id$='name']

This will get you all a elements with id containing

Some:Same

and have the id ending in

name

Happened to me when didn't install angular core:

Angular CLI: 9.0.0-rc.0
Node: 11.12.0
OS: darwin x64
Angular: undefined
...

So I run

npm i @angular/core

which gave me ng -v

Angular CLI: 9.0.0-rc.0
Node: 11.12.0
OS: darwin x64
Angular: 8.2.13
... core

Then I run

ng update @angular/cli --migrate-only --from=8.2.13

removed node_modules

npm install
cd <project name>
ng serve

And it worked!

You can first choose which cells you don't want to be protected (to be user-editable) by setting the Locked status of them to False:

Worksheets("Sheet1").Range("B2:C3").Locked = False

Then, you can protect the sheet, and all the other cells will be protected. The code to do this, and still allow your VBA code to modify the cells is:

Worksheets("Sheet1").Protect UserInterfaceOnly:=True

or

Call Worksheets("Sheet1").Protect(UserInterfaceOnly:=True)

Here is the code how to get extract the hashmap into arrays, hashmap that contains arraylist

Map<String, List<String>> country_hashmap = new HashMap<String, List<String>>();

//Creating two lists and inserting some data in it
List<String> list_1 = new ArrayList<String>();
list_1.add("16873538.webp");
list_1.add("16873539.webp");

List<String> list_2 = new ArrayList<String>();
list_2.add("16873540.webp");
list_2.add("16873541.webp");

//Inserting both the lists and key to the Map 
country_hashmap.put("Malaysia", list_1);
country_hashmap.put("Japanese", list_2);

for(Map.Entry<String, List<String>> hashmap_data : country_hashmap.entrySet()){
      String key = hashmap_data.getKey(); // contains the keys
      List<String> val = hashmap_data.getValue(); // contains arraylists
      // print all the key and values in the hashmap
      System.out.println(key + ": " +val);
      
      // using interator to get the specific values arraylists
      Iterator<String> itr = val.iterator();
      int i = 0;
      String[] data = new String[val.size()];
        while (itr.hasNext()){
            String array = itr.next();
            data[i] = array;
            System.out.println(data[i]); // GET THE VALUE
            i++;
        }
  }

Bjarne Stroustrup's example in his C++ FAQ suggests you are correct, and only need a definition if you take the address.

class AE {
    // ...
public:
    static const int c6 = 7;
    static const int c7 = 31;
};

const int AE::c7;   // definition

int f()
{
    const int* p1 = &AE::c6;    // error: c6 not an lvalue
    const int* p2 = &AE::c7;    // ok
    // ...
}

He says "You can take the address of a static member if (and only if) it has an out-of-class definition". Which suggests it would work otherwise. Maybe your min function invokes addresses somehow behind the scenes.

PHP is evaluated at the server; javascript is evaluated at the client/browser, thus you can't call a PHP function from javascript directly. But you can issue an HTTP request to the server that will activate a PHP function, with AJAX.

You started with ManyToOne mapping , then you put OneToMany mapping as well for BiDirectional way. Then at OneToMany side (usually your parent table/class), you have to mention "mappedBy" (mapping is done by and in child table/class), so hibernate will not create EXTRA mapping table in DB (like TableName = parent_child).

In case someone is looking for a universal event handler the following code can be used more or less (assuming that name property is set for every input):

    this.handleInputChange = (e) => {
        item[e.target.name] = e.target.type === "checkbox" ? e.target.checked : e.target.value;
    }

There are two ways you can do that

1. Start Your comment with "<!--" then end your comment with "-->"

   Example <!-- my comment goes here -->

2. Highlight the part you want to comment and press CTRL + SHIFT + /

I always prefer List and I use "fold/reduce" before "for comprehension". However, "for comprehension" is preferred if nested "folds" are required. Recursion is the last resort if I can not accomplish the task using "fold/reduce/for".

so for your example, I will do:

((0 to 3) :\ List[Int]())(_ :: _)

before I do:

(for (x <- 0 to 3) yield x).toList

Note: I use "foldRight(:\)" instead of "foldLeft(/:)" here because of the order of "_"s. For a version that does not throw StackOverflowException, use "foldLeft" instead.

Once I had this "simple" task and I used (new Date()).getTimezoneOffset() - the approach that is widely suggested here. But it turned out that the solution wasn't quite right. For some undocumented reasons in my case new Date() was returning GMT+0200 when new Date(0) was returning GMT+0300 which was right. Since then I always use

(new Date(0)).getTimezoneOffset() to get a correct timeshift.

A Problem with csgillespie solution appears, when You have an logarithmic X axis. The you will have a different length of the small bars on the right an the left side (the epsilon follows the x-values).

You should better use the errbar function from the Hmisc package:

d = data.frame(
  x  = c(1:5)
  , y  = c(1.1, 1.5, 2.9, 3.8, 5.2)
  , sd = c(0.2, 0.3, 0.2, 0.0, 0.4)
)

##install.packages("Hmisc", dependencies=T)
library("Hmisc")

# add error bars (without adjusting yrange)
plot(d$x, d$y, type="n")
with (
  data = d
  , expr = errbar(x, y, y+sd, y-sd, add=T, pch=1, cap=.1)
)

# new plot (adjusts Yrange automatically)
with (
  data = d
  , expr = errbar(x, y, y+sd, y-sd, add=F, pch=1, cap=.015, log="x")
)

Java 8 added a new API for working with dates and times. With Java 8 you can use

import java.time.Instant
...
long unixTimestamp = Instant.now().getEpochSecond();

Instant.now() returns an Instant that represents the current system time. With getEpochSecond() you get the epoch seconds (unix time) from the Instant.

Assuming that you didn't set a precision initially, it's assumed to be the maximum (38). You're reducing the precision because you're changing it from 38 to 14.

The easiest way to handle this is to rename the column, copy the data over, then drop the original column:

alter table EVAPP_FEES rename column AMOUNT to AMOUNT_OLD;

alter table EVAPP_FEES add AMOUNT NUMBER(14,2);

update EVAPP_FEES set AMOUNT = AMOUNT_OLD;

alter table EVAPP_FEES drop column AMOUNT_OLD;

If you really want to retain the column ordering, you can move the data twice instead:

alter table EVAPP_FEES add AMOUNT_TEMP NUMBER(14,2);

update EVAPP_FEES set AMOUNT_TEMP = AMOUNT;

update EVAPP_FEES set AMOUNT = null;

alter table EVAPP_FEES modify AMOUNT NUMBER(14,2);

update EVAPP_FEES set AMOUNT = AMOUNT_TEMP;

alter table EVAPP_FEES drop column AMOUNT_TEMP;

I've tried both these and still get failure due to conflicts. At the end of my patience, I cloned master in another location, copied everything into the other branch and committed it. which let me continue. The "-X theirs" option should have done this for me, but it did not.

git merge -s recursive -X theirs master

Cong Ma does a good job of explaining what __getitem__ is used for - but I want to give you an example which might be useful. Imagine a class which models a building. Within the data for the building it includes a number of attributes, including descriptions of the companies that occupy each floor :

Without using __getitem__ we would have a class like this :

class Building(object):
     def __init__(self, floors):
         self._floors = [None]*floors
     def occupy(self, floor_number, data):
          self._floors[floor_number] = data
     def get_floor_data(self, floor_number):
          return self._floors[floor_number]

building1 = Building(4) # Construct a building with 4 floors
building1.occupy(0, 'Reception')
building1.occupy(1, 'ABC Corp')
building1.occupy(2, 'DEF Inc')
print( building1.get_floor_data(2) )

We could however use __getitem__ (and its counterpart __setitem__) to make the usage of the Building class 'nicer'.

class Building(object):
     def __init__(self, floors):
         self._floors = [None]*floors
     def __setitem__(self, floor_number, data):
          self._floors[floor_number] = data
     def __getitem__(self, floor_number):
          return self._floors[floor_number]

building1 = Building(4) # Construct a building with 4 floors
building1[0] = 'Reception'
building1[1] = 'ABC Corp'
building1[2] = 'DEF Inc'
print( building1[2] )

Whether you use __setitem__ like this really depends on how you plan to abstract your data - in this case we have decided to treat a building as a container of floors (and you could also implement an iterator for the Building, and maybe even the ability to slice - i.e. get more than one floor's data at a time - it depends on what you need.

you can use toggleClass() to toggle class it is really handy.

case:1

<div id='mydiv' class="class1"></div>

$('#mydiv').toggleClass('class1 class2');

output: <div id='mydiv' class="class2"></div>

case:2

<div id='mydiv' class="class2"></div>

$('#mydiv').toggleClass('class1 class2');

output: <div id='mydiv' class="class1"></div>

case:3

<div id='mydiv' class="class1 class2 class3"></div>

$('#mydiv').toggleClass('class1 class2');

output: <div id='mydiv' class="class3"></div>

• In Python, you wouldn't use indexes for this at all, but just deal with the values—[value for value in a if value > 2]. Usually dealing with indexes means you're not doing something the best way.

• If you do need an API similar to Matlab's, you would use numpy, a package for multidimensional arrays and numerical math in Python which is heavily inspired by Matlab. You would be using a numpy array instead of a list.

  >>> import numpy
  >>> a = numpy.array([1, 2, 3, 1, 2, 3])
  >>> a
  array([1, 2, 3, 1, 2, 3])
  >>> numpy.where(a > 2)
  (array([2, 5]),)
  >>> a > 2
  array([False, False,  True, False, False,  True], dtype=bool)
  >>> a[numpy.where(a > 2)]
  array([3, 3])
  >>> a[a > 2]
  array([3, 3])
  

This works:

myWindow = window.open('http://www.yahoo.com','myWindow', "width=200, height=200");

You can minimize this function in a lot of way, and you can also implement it with a custom regex for negative values or custom charts:

$('.number').on('input',function(){
    var n=$(this).val().replace(/ /g,'').replace(/\D/g,'');
    if (!$.isNumeric(n))
        $(this).val(n.slice(0, -1))
    else
        $(this).val(n)
});

you need nested foreach loops

foreach($samplearr as $key => $item){
   echo $key;
    foreach($item as $detail){
       echo $detail['value1'] . " " . $detail['value2']
     }
 }

ax.set_title() should set the titles for separate subplots:

import matplotlib.pyplot as plt

if __name__ == "__main__":
    data = [1, 2, 3, 4, 5]

    fig = plt.figure()
    fig.suptitle("Title for whole figure", fontsize=16)
    ax = plt.subplot("211")
    ax.set_title("Title for first plot")
    ax.plot(data)

    ax = plt.subplot("212")
    ax.set_title("Title for second plot")
    ax.plot(data)

    plt.show()

Can you check if this code works for you? Maybe something overwrites them later?

There's at least one situation in which you want sys.stdout instead of print.

When you want to overwrite a line without going to the next line, for instance while drawing a progress bar or a status message, you need to loop over something like

Note carriage return-> "\rMy Status Message: %s" % progress

And since print adds a newline, you are better off using sys.stdout.

Following is my TypeScript code which can be converted easily into JavaScript and you can use

/**
 * Convert BASE64 to BLOB
 * @param base64Image Pass Base64 image data to convert into the BLOB
 */
private convertBase64ToBlob(base64Image: string) {
  // Split into two parts
  const parts = base64Image.split(';base64,');

  // Hold the content type
  const imageType = parts[0].split(':')[1];

  // Decode Base64 string
  const decodedData = window.atob(parts[1]);

  // Create UNIT8ARRAY of size same as row data length
  const uInt8Array = new Uint8Array(decodedData.length);

  // Insert all character code into uInt8Array
  for (let i = 0; i < decodedData.length; ++i) {
    uInt8Array[i] = decodedData.charCodeAt(i);
  }

  // Return BLOB image after conversion
  return new Blob([uInt8Array], { type: imageType });
}

If you are getting this Error java.lang.OutOfMemoryError this is the most common problem occurs in Android. This error is thrown by the Java Virtual Machine (JVM) when an object cannot be allocated due to lack of memory space.

Try this android:hardwareAccelerated="false" , android:largeHeap="true"in your manifest.xml file under application like this:

<application
  android:name=".MyApplication"
  android:allowBackup="true"
  android:icon="@mipmap/ic_launcher"
  android:label="@string/app_name"
  android:theme="@style/AppTheme"
  android:hardwareAccelerated="false"
  android:largeHeap="true" />

I have the same problem. None of the options suggested above worked for me. However I find, that if I lets say manually add groupid/artifact/version for org.springframework.spring-core version 4.3.4.RELEASE and save the pom.xml, the dependencies download automatically and the search works for the jars already present in the repository. However if I now search for org.springframework.spring-context , which isnt in the current dependencies, this search still doesn't work.

The other methods are all good. However, if you prefer to not specify the field (e.g. for some dynamic method), you can use this:

def __init__(self, *args, **kwargs):
    super(MyForm, self).__init__(*args, **kwargs)
    self.fields['email'].widget.attrs['placeholder'] = self.fields['email'].label or '[email protected]'

It also allows the placeholder to depend on the instance for ModelForms with instance specified.

you need to do something like this,

SELECT * FROM buckets WHERE bucketname RLIKE 'Stylus.*2100';

or

SELECT * FROM buckets WHERE bucketname RLIKE '(Stylus)+.*(2100)+';

If you don't mind using gVim, you can launch a single instance, so that when a new file is opened with it it's automatically opened in a new tab in the currently running instance.

to do this you can write: gVim --remote-tab-silent file

You could always make an alias to this command so that you don't have to type so many words. For example I use linux and bash and in my ~/.bashrc file I have:

alias g='gvim --remote-tab-silent'

so instead of doing $ mate file I do: $ g file

Check your URL's protocol.

You will also see this error if you host an encrypted page (https) and open it as plain text (http) in Firefox.

Use numpy.full. Here's a Python that creates a gray, blue, green and red image and shows in a 2x2 grid.

import cv2
import numpy as np

gray_img = np.full((100, 100, 3), 127, np.uint8)

blue_img = np.full((100, 100, 3), 0, np.uint8)
green_img = np.full((100, 100, 3), 0, np.uint8)
red_img = np.full((100, 100, 3), 0, np.uint8)

full_layer = np.full((100, 100), 255, np.uint8)

# OpenCV goes in blue, green, red order
blue_img[:, :, 0] = full_layer
green_img[:, :, 1] = full_layer
red_img[:, :, 2] = full_layer

cv2.imshow('2x2_grid', np.vstack([
    np.hstack([gray_img, blue_img]), 
    np.hstack([green_img, red_img])
]))
cv2.waitKey(0)
cv2.destroyWindow('2x2_grid')

The only way that worked for me, is by copying the dll into your desktop or something, add reference to it, then delete the dll from your desktop. Visual Studio will refresh itself, and will finally reference the dll from the GAC on itself.

There's no standard for the layout of the LIST response. You'd have to write code to handle the most popular layouts. I'd start with Linux ls and Windows Server DIR formats. There's a lot of variety out there, though.

Fall back to the nlst method (returning the result of the NLST command) if you can't parse the longer list. For bonus points, cheat: perhaps the longest number in the line containing a known file name is its length.

You can listen resize event and fire where some dimension change

directive

(function() {
'use strict';

    angular
    .module('myApp.directives')
    .directive('resize', ['$window', function ($window) {
        return {
            link: link,
            restrict: 'A'
        };

        function link(scope, element, attrs){
            scope.width = $window.innerWidth;
            function onResize(){
                // uncomment for only fire when $window.innerWidth change   
                // if (scope.width !== $window.innerWidth)
                {
                    scope.width = $window.innerWidth;
                    scope.$digest();
                }
            };

            function cleanUp() {
                angular.element($window).off('resize', onResize);
            }

            angular.element($window).on('resize', onResize);
            scope.$on('$destroy', cleanUp);
        }
    }]);
})();

In html

<div class="row" resize> ,
    <div class="col-sm-2 col-xs-6" ng-repeat="v in tag.vod"> 
        <h4 ng-bind="::v.known_as"></h4>
    </div> 
</div> 

Controller :

$scope.$watch('width', function(old, newv){
     console.log(old, newv);
 })

The RIGHT way...

The following methods actually work.

if you wish - using a theme
By default a buttons color is android:colorAccent. So, if you create a style like this...

<style name="Button.White" parent="ThemeOverlay.AppCompat">
    <item name="colorAccent">@android:color/white</item>
</style>

You can use it like this...

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:theme="@style/Button.White"
    />

alternatively - using a tint
You can simply add android:backgroundTint for API Level 21 and higher, or app:backgroundTint for API Level 7 and higher.

For more information, see this blog.

The problem with the accepted answer...

If you replace the background with a color you will loose the effect of the button, and the color will be applied to the entire area of the button. It will not respect the padding, shadow, and corner radius.

Try putting double quotes in your filepath variable

"\"E:/ABC/SEM 2/testfiles/all.txt\""

Check the permissions of the file or in any case consider renaming the folder to remove the space

If you're printing to stdout, it depends on the terminal you're printing to. You can use ansi escape codes on xterms and other similar terminal emulators. Here's a bash code snippet that will print all 255 colors supported by xterm, putty and Konsole:

 for ((i=0;i<256;i++)); do echo -en "\e[38;5;"$i"m"$i" "; done

You can use these escape codes in any programming language. It's better to rely on a library that will decide which codes to use depending on architecture and the content of the TERM environment variable.

You can pass in the hostname as an environment variable. You could also mount /etc so you can cat /etc/hostname. But I agree with Vitaly, this isn't the intended use case for containers IMO.

DISTINCT is the keyword
For me your query is correct

Just try to do this first

SELECT DISTINCT title,id FROM tbl_countries

Later on you can try with order by.

Just Type:

ec2metadata --instance-id

I was facing the same issues recently and found a solution which worked for me and reduced the memory consumption level upto a great extent.

Solution:

First of all find the application which is causing heavy memory usage.

You can find this in the Details section of the Task Manager.

Next.

1. Open the IIS manager.
2. Click on Application Pools. You'll find many application pools which your system is using.
3. Now from the task manager you've found which application is causing the heavy memory consumption. There would be multiple options for that and you need to select the one which is having '1' in it's Application column of your web application.
4. When you click on the application pool on the right hand side you'll see an option Advance settings under Edit Application pools. Go to Advanced Settings. 5.Now under General category set the Enable 32-bit Applications to True
5. Restart the IIS server or you can see the consumption goes down in performance section of your Task Manager.

If this solution works for you please add a comment so that I can know.

If you're using Typescript and want to match on a single property value, this should work based on Craciun Ciprian's answer above.

You could also make this more generic by allowing non-object matching and / or multi-property value matching.

/**
 *
 * @param arr1 The initial array
 * @param arr2 The array to remove
 * @param propertyName the key of the object to match on
 */
function differenceByPropVal<T>(arr1: T[], arr2: T[], propertyName: string): T[] {
  return arr1.filter(
    (a: T): boolean =>
      !arr2.find((b: T): boolean => b[propertyName] === a[propertyName])
  );
}

There does appear to be a solution to this that does not rely on polling (at least for Chrome). It is almost as hackish, but I do think is marginally better than global polling.

Consider the following scenario:

1. User starts to fill out field1

2. User selects an autocomplete suggestion which autofills field2 and field3

Solution: Register an onblur on all fields that checks for the presence of auto-filled fields via the following jQuery snippet $(':-webkit-autofill')

This won't be immediate since it will be delayed until the user blurs field1 but it doesn't rely on global polling so IMO, it is a better solution.

That said, since hitting the enter key can submit a form, you may also need a corresponding handler for onkeypress.

Alternately, you can use global polling to check $(':-webkit-autofill')

In my Visual Studio 2019 it worked only after I set the AutoSizeColumnsMode property to None.

Using constants allows to combine multiple fields for verification:

The Kafka clients no longer require zookeeper but the Kafka servers do need it to operate.

You can get a list of topics with the new AdminClient API but the shell command that ship with Kafka have not yet been rewritten to use this new API.

The other way to use Kafka without Zookeeper is to use a SaaS Kafka-as-a-Service provider such as Confluent Cloud so you don’t see or operate the Kafka brokers (and the required backend Zookeeper ensemble).

For example on Confluent Cloud you would just use the following zookeeper free CLI command:

ccloud topic list

uint16_t log2(uint32_t n) {//but truncated
     if (n==0) throw ...
     uint16_t logValue = -1;
     while (n) {//
         logValue++;
         n >>= 1;
     }
     return logValue;
 }

Basically the same as tomlogic's.

You can use

php artisan serve --port 80

You should use the @JsonProperty on the field you want to change the default name mapping.

class User{
    @JsonProperty("first_name")
    protected String firstName;
    protected String getFirstName(){return firstName;}
}

This event works to me:

@keyup.enter.native="onEnter".

Swift 4:

tableView.deselectRow(at: indexPath, animated: true)

Think about it. When your client makes a GET request to an URI X, what it's saying to the server is: "I want a representation of the resource located at X, and this operation shouldn't change anything on the server." A PUT request is saying: "I want you to replace whatever is the resource located at X with the new entity I'm giving you on the body of this request". A DELETE request is saying: "I want you to delete whatever is the resource located at X". A PATCH is saying "I'm giving you this diff, and you should try to apply it to the resource at X and tell me if it succeeds." But a POST is saying: "I'm sending you this data subordinated to the resource at X, and we have a previous agreement on what you should do with it."

If you don't have it documented somewhere that the resource expects a POST and does something with it, it doesn't make sense to send a POST to it expecting it to act like a GET.

REST relies on the standardized behavior of the underlying protocol, and POST is precisely the method used for an action that isn't standardized. The result of a GET, PUT and DELETE requests are clearly defined in the standard, but POST isn't. The result of a POST is subordinated to the server, so if it's not documented that you can use POST to do something, you have to assume that you can't.

   dt = abj.getDataTable(
"select bookrecord.userid,usermaster.userName, "
                                                +" book.bookname,bookrecord.fromdate, "
                                                +" bookrecord.todate,bookrecord.bookstatus "

                                                +" where bookrecord.bookid='"+ bookId +"' "
                                                +" and usermaster.userId=bookrecord.userid "

#Script for calculating various values in MB
echo "Please enter some input: "
read input_variable
echo $input_variable | awk '{ foo = $1 / 1024 / 1024 ; print foo "MB" }'

That won't work if the string contains more than one match... try this:

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; system( "echo "  $0) }'

or better (if the echo isn't a placeholder for something else):

echo "/x/y/z/x" | awk '{ gsub("/", "_") ; print $0 }'

In your case you want to make a copy of the value before changing it:

echo "/x/y/z/x" | awk '{ c=$0; gsub("/", "_", c) ; system( "echo " $0 " " c )}'

If, despite all the other answers, you still want to traditionally include a file in a node.js source file, you can use this:

var fs = require('fs');

// file is included here:
eval(fs.readFileSync('tools.js')+'');

• The empty string concatenation +'' is necessary to get the file content as a string and not an object (you can also use .toString() if you prefer).
• The eval() can't be used inside a function and must be called inside the global scope otherwise no functions or variables will be accessible (i.e. you can't create a include() utility function or something like that).

Please note that in most cases this is bad practice and you should instead write a module. However, there are rare situations, where pollution of your local context/namespace is what you really want.

Update 2015-08-06

Please also note this won't work with "use strict"; (when you are in "strict mode") because functions and variables defined in the "imported" file can't be accessed by the code that does the import. Strict mode enforces some rules defined by newer versions of the language standard. This may be another reason to avoid the solution described here.

In material UI and react.js you can use the grid

<Grid
  container
  direction="row"
  justify="center"
  alignItems="center"
>
    <Grid item xs>
      <Paper className={classes.paper}>xs</Paper>
    </Grid>
    <Grid item xs>
      <Paper className={classes.paper}>xs</Paper>
    </Grid>
    <Grid item xs>
      <Paper className={classes.paper}>xs</Paper>
    </Grid>

</Grid>

Casting is necessary to tell that you are calling a child and not a parent method. So it's ever downward. However if the method is already defined in the parent class and overriden in the child class, you don't any cast. Here an example:

class Parent{
   void method(){ System.out.print("this is the parent"); }
}

class Child extends Parent{
   @override
   void method(){ System.out.print("this is the child"); }
}
...
Parent o = new Child();
o.method();
((Child)o).method();  

The two method call will both print : "this is the child".

Simple, global change of Jupyter font size and inner & outer background colors (this change will affect all notebooks).

In Windows, find config directory by running a command: jupyter --config-dir

In Linux it is ~/.jupyter

In this directory create subfolder custom Create file custom.css and paste:

/* Change outer background and make the notebook take all available width */
.container {
    width: 99% !important;
    background: #DDC !important;
}   

/* Change inner background (CODE) */
div.input_area {
    background: #F4F4E2 !important;
    font-size: 16px !important;
}

/* Change global font size (CODE) */
.CodeMirror {
    font-size: 16px !important;
}  

/* Prevent the edit cell highlight box from getting clipped;
 * important so that it also works when cell is in edit mode */
div.cell.selected {
    border-left-width: 1px !important;
} 

Finally - restart Jupyter. Result:

I'm getting OpenJDK 8 from the official Debian repositories, rather than some random PPA or non-free Oracle binary. Here's how I did it:

sudo apt-get install debian-keyring debian-archive-keyring

Make /etc/apt/sources.list.d/debian-jessie-backports.list:

deb http://httpredir.debian.org/debian/ jessie-backports main

Make /etc/apt/preferences.d/debian-jessie-backports:

Package: *
Pin: release o=Debian,a=jessie-backports
Pin-Priority: -200

Then finally do the install:

sudo apt-get update
sudo apt-get -t jessie-backports install openjdk-8-jdk

The normal way of doing it is:

• You get the users from the database in controller.
• You send a collection of users to the View
• In the view to loop the list of users building the list.

You don't need a JsonResult or jQuery for this.

this works:

if (WindowState == FormWindowState.Minimized)
    WindowState = FormWindowState.Normal;
else
{
    TopMost = true;
    Focus();
    BringToFront();
    TopMost = false;
}

For me a Git repository (not GitHub) was already created, but empty. This was my solution for adding the existing project to the Git repository:

1. I cloned and checked out a repository with Git Extensions.
2. Then I copied my existing project files into this repository.
3. Added a .gitignore file.
4. Staged and committed all files.
5. Pushed onto the remote repository.

It would be interesting to see this all done directly in Visual Studio 2015 without tools like Git Extensions, but the things I tried in Visual Studio didn't work (Add to source control is not available for my project, adding a remote didn't help, etc.).

Figured since this is still showing up high in search results for C# and ZPL I should mention SharpZebra. It's only EPL2, but I've submitted an update that adds ZPL support along with printing via sockets, the Windows Spool Service and direct USB.

I recommend more understanding way using extension method:

public static class KeyValuePairExtensions
{
    public static bool IsNull<T, TU>(this KeyValuePair<T, TU> pair)
    {
        return pair.Equals(new KeyValuePair<T, TU>());
    }
}

And then just use:

var countries = new Dictionary<string, string>
{
    {"cz", "prague"},
    {"de", "berlin"}
};

var country = countries.FirstOrDefault(x => x.Key == "en");

if(country.IsNull()){

}

If you have already installed MySQL on a windows machine make sure it is running as a service.. You can do that by

Start --> services --> MySQL(ver) --> Right-Click --> Start

This is an adapted version of the answer given by Vivien Barousse with the update from Vulcan applied. In this example I use sliders to dynamically retreive the RGB values from three sliders and display that color in a rectangle. Then in method toHex() I use the values to create a color and display the respective Hex color code.

This example does not include the proper constraints for the GridBagLayout. Though the code will work, the display will look strange.

public class HexColor
{

  public static void main (String[] args)
  {
   JSlider sRed = new JSlider(0,255,1);
   JSlider sGreen = new JSlider(0,255,1);
   JSlider sBlue = new JSlider(0,255,1);
   JLabel hexCode = new JLabel();
   JPanel myPanel = new JPanel();
   GridBagLayout layout = new GridBagLayout();
   JFrame frame = new JFrame();

   //set frame to organize components using GridBagLayout 
   frame.setLayout(layout);

   //create gray filled rectangle 
   myPanel.paintComponent();
   myPanel.setBackground(Color.GRAY);

   //In practice this code is replicated and applied to sGreen and sBlue. 
   //For the sake of brevity I only show sRed in this post.
   sRed.addChangeListener(
         new ChangeListener()
         {
             @Override
             public void stateChanged(ChangeEvent e){
                 myPanel.setBackground(changeColor());
                 myPanel.repaint();
                 hexCode.setText(toHex());
         }
         }
     );
   //add each component to JFrame
   frame.add(myPanel);
   frame.add(sRed);
   frame.add(sGreen);
   frame.add(sBlue);
   frame.add(hexCode);
} //end of main

  //creates JPanel filled rectangle
  protected void paintComponent(Graphics g)
  {
      super.paintComponent(g);
      g.drawRect(360, 300, 10, 10);
      g.fillRect(360, 300, 10, 10);
  }

  //changes the display color in JPanel
  private Color changeColor()
  {
    int r = sRed.getValue();
    int b = sBlue.getValue();
    int g = sGreen.getValue();
    Color c;
    return  c = new Color(r,g,b);
  }

  //Displays hex representation of displayed color
  private String toHex()
  {
      Integer r = sRed.getValue();
      Integer g = sGreen.getValue();
      Integer b = sBlue.getValue();
      Color hC;
      hC = new Color(r,g,b);
      String hex = Integer.toHexString(hC.getRGB() & 0xffffff);
      while(hex.length() < 6){
          hex = "0" + hex;
      }
      hex = "Hex Code: #" + hex;
      return hex;
  }
}

A huge thank you to both Vivien and Vulcan. This solution works perfectly and was super simple to implement.

I was having a text something like:

Forgot Password? Reset here.

To implement this the easy way I used the existing android:textStyle="bold"

<LinearLayout
        android:id="@+id/forgotPassword"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:gravity="center"
        >


        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:autoLink="all"
            android:linksClickable="false"
            android:selectAllOnFocus="false"

            android:text="Forgot password? "
            android:textAlignment="center"
            android:textColor="@android:color/white"
            />

        <TextView

            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:autoLink="all"
            android:linksClickable="false"
            android:selectAllOnFocus="false"

            android:text="Reset here"
            android:textAlignment="center"
            android:textColor="@android:color/white"
            android:textStyle="bold" />
    </LinearLayout>

Maybe it helps someone

The first thing you should do with date variables is confirm that R reads it as a Date. To do this, for the variable (i.e. vector/column) called Date, in the data frame called EPL2011_12, input

class(EPL2011_12$Date)

The output should read [1] "Date". If it doesn't, you should format it as a date by inputting

EPL2011_12$Date <- as.Date(EPL2011_12$Date, "%d-%m-%y")

Note that the hyphens in the date format ("%d-%m-%y") above can also be slashes ("%d/%m/%y"). Confirm that R sees it as a Date. If it doesn't, try a different formatting command

EPL2011_12$Date <- format(EPL2011_12$Date, format="%d/%m/%y")

Once you have it in Date format, you can use the subset command, or you can use brackets

WhateverYouWant <- EPL2011_12[EPL2011_12$Date > as.Date("2014-12-15"),]

This will delete all the files in a directory (and below) that are size zero.

find /tmp -size  0 -print -delete

If you just want a particular file;

if [ ! -s /tmp/foo ] ; then
  rm /tmp/foo
fi

So at the most basic level a HANDLE of any sort is a pointer to a pointer or

#define HANDLE void **

Now as to why you would want to use it

Lets take a setup:

class Object{
   int Value;
}

class LargeObj{

   char * val;
   LargeObj()
   {
      val = malloc(2048 * 1000);
   }

}

void foo(Object bar){
    LargeObj lo = new LargeObj();
    bar.Value++;
}

void main()
{
   Object obj = new Object();
   obj.val = 1;
   foo(obj);
   printf("%d", obj.val);
}

So because obj was passed by value (make a copy and give that to the function) to foo, the printf will print the original value of 1.

Now if we update foo to:

void foo(Object * bar)
{
    LargeObj lo = new LargeObj();
    bar->val++;
}

There is a chance that the printf will print the updated value of 2. But there is also the possibility that foo will cause some form of memory corruption or exception.

The reason is this while you are now using a pointer to pass obj to the function you are also allocating 2 Megs of memory, this could cause the OS to move the memory around updating the location of obj. Since you have passed the pointer by value, if obj gets moved then the OS updates the pointer but not the copy in the function and potentially causing problems.

A final update to foo of:

void foo(Object **bar){
    LargeObj lo = LargeObj();
    Object * b = &bar;
    b->val++;
}

This will always print the updated value.

See, when the compiler allocates memory for pointers it marks them as immovable, so any re-shuffling of memory caused by the large object being allocated the value passed to the function will point to the correct address to find out the final location in memory to update.

Any particular types of HANDLEs (hWnd, FILE, etc) are domain specific and point to a certain type of structure to protect against memory corruption.

What is Dependency Injection (DI)?

As others have said, Dependency Injection(DI) removes the responsibility of direct creation, and management of the lifespan, of other object instances upon which our class of interest (consumer class) is dependent (in the UML sense). These instances are instead passed to our consumer class, typically as constructor parameters or via property setters (the management of the dependency object instancing and passing to the consumer class is usually performed by an Inversion of Control (IoC) container, but that's another topic).

DI, DIP and SOLID

Specifically, in the paradigm of Robert C Martin's SOLID principles of Object Oriented Design, DI is one of the possible implementations of the Dependency Inversion Principle (DIP). The DIP is the D of the SOLID mantra - other DIP implementations include the Service Locator, and Plugin patterns.

The objective of the DIP is to decouple tight, concrete dependencies between classes, and instead, to loosen the coupling by means of an abstraction, which can be achieved via an interface, abstract class or pure virtual class, depending on the language and approach used.

Without the DIP, our code (I've called this 'consuming class') is directly coupled to a concrete dependency and is also often burdened with the responsibility of knowing how to obtain, and manage, an instance of this dependency, i.e. conceptually:

"I need to create/use a Foo and invoke method `GetBar()`"

Whereas after application of the DIP, the requirement is loosened, and the concern of obtaining and managing the lifespan of the Foo dependency has been removed:

"I need to invoke something which offers `GetBar()`"

Why use DIP (and DI)?

Decoupling dependencies between classes in this way allows for easy substitution of these dependency classes with other implementations which also fulfil the prerequisites of the abstraction (e.g. the dependency can be switched with another implementation of the same interface). Moreover, as others have mentioned, possibly the most common reason to decouple classes via the DIP is to allow a consuming class to be tested in isolation, as these same dependencies can now be stubbed and/or mocked.

One consequence of DI is that the lifespan management of dependency object instances is no longer controlled by a consuming class, as the dependency object is now passed into the consuming class (via constructor or setter injection).

This can be viewed in different ways:

• If lifespan control of dependencies by the consuming class needs to be retained, control can be re-established by injecting an (abstract) factory for creating the dependency class instances, into the consumer class. The consumer will be able to obtain instances via a Create on the factory as needed, and dispose of these instances once complete.
• Or, lifespan control of dependency instances can be relinquished to an IoC container (more about this below).

When to use DI?

• Where there likely will be a need to substitute a dependency for an equivalent implementation,
• Any time where you will need to unit test the methods of a class in isolation of its dependencies,
• Where uncertainty of the lifespan of a dependency may warrant experimentation (e.g. Hey, MyDepClass is thread safe - what if we make it a singleton and inject the same instance into all consumers?)

Example

Here's a simple C# implementation. Given the below Consuming class:

public class MyLogger
{
   public void LogRecord(string somethingToLog)
   {
      Console.WriteLine("{0:HH:mm:ss} - {1}", DateTime.Now, somethingToLog);
   }
}

Although seemingly innocuous, it has two static dependencies on two other classes, System.DateTime and System.Console, which not only limit the logging output options (logging to console will be worthless if no one is watching), but worse, it is difficult to automatically test given the dependency on a non-deterministic system clock.

We can however apply DIP to this class, by abstracting out the the concern of timestamping as a dependency, and coupling MyLogger only to a simple interface:

public interface IClock
{
    DateTime Now { get; }
}

We can also loosen the dependency on Console to an abstraction, such as a TextWriter. Dependency Injection is typically implemented as either constructor injection (passing an abstraction to a dependency as a parameter to the constructor of a consuming class) or Setter Injection (passing the dependency via a setXyz() setter or a .Net Property with {set;} defined). Constructor Injection is preferred, as this guarantees the class will be in a correct state after construction, and allows the internal dependency fields to be marked as readonly (C#) or final (Java). So using constructor injection on the above example, this leaves us with:

public class MyLogger : ILogger // Others will depend on our logger.
{
    private readonly TextWriter _output;
    private readonly IClock _clock;

    // Dependencies are injected through the constructor
    public MyLogger(TextWriter stream, IClock clock)
    {
        _output = stream;
        _clock = clock;
    }

    public void LogRecord(string somethingToLog)
    {
        // We can now use our dependencies through the abstraction 
        // and without knowledge of the lifespans of the dependencies
        _output.Write("{0:yyyy-MM-dd HH:mm:ss} - {1}", _clock.Now, somethingToLog);
    }
}

(A concrete Clock needs to be provided, which of course could revert to DateTime.Now, and the two dependencies need to be provided by an IoC container via constructor injection)

An automated Unit Test can be built, which definitively proves that our logger is working correctly, as we now have control over the dependencies - the time, and we can spy on the written output:

[Test]
public void LoggingMustRecordAllInformationAndStampTheTime()
{
    // Arrange
    var mockClock = new Mock<IClock>();
    mockClock.Setup(c => c.Now).Returns(new DateTime(2015, 4, 11, 12, 31, 45));
    var fakeConsole = new StringWriter();

    // Act
    new MyLogger(fakeConsole, mockClock.Object)
        .LogRecord("Foo");

    // Assert
    Assert.AreEqual("2015-04-11 12:31:45 - Foo", fakeConsole.ToString());
}

Next Steps

Dependency injection is invariably associated with an Inversion of Control container(IoC), to inject (provide) the concrete dependency instances, and to manage lifespan instances. During the configuration / bootstrapping process, IoC containers allow the following to be defined:

• mapping between each abstraction and the configured concrete implementation (e.g. "any time a consumer requests an IBar, return a ConcreteBar instance")
• policies can be set up for the lifespan management of each dependency, e.g. to create a new object for each consumer instance, to share a singleton dependency instance across all consumers, to share the same dependency instance only across the same thread, etc.
• In .Net, IoC containers are aware of protocols such as IDisposable and will take on the responsibility of Disposing dependencies in line with the configured lifespan management.

Typically, once IoC containers have been configured / bootstrapped, they operate seamlessly in the background allowing the coder to focus on the code at hand rather than worrying about dependencies.

The key to DI-friendly code is to avoid static coupling of classes, and not to use new() for the creation of Dependencies

As per above example, decoupling of dependencies does require some design effort, and for the developer, there is a paradigm shift needed to break the habit of newing dependencies directly, and instead trusting the container to manage dependencies.

But the benefits are many, especially in the ability to thoroughly test your class of interest.

Note : The creation / mapping / projection (via new ..()) of POCO / POJO / Serialization DTOs / Entity Graphs / Anonymous JSON projections et al - i.e. "Data only" classes or records - used or returned from methods are not regarded as Dependencies (in the UML sense) and not subject to DI. Using new to project these is just fine.

the Jquery append function returns a jQuery object so you can just tag a method on the end

$("#root").append(child).anotherJqueryMethod();

Try:

mmatrix = np.zeros((nrows, ncols))

Since the shape parameter has to be an int or sequence of ints

http://docs.scipy.org/doc/numpy/reference/generated/numpy.zeros.html

Otherwise you are passing ncols to np.zeros as the dtype.

Hey define color #000 into as like you and modify your css as like this

.navBtn { text-decoration: none; color:#000; }
.navBtn:visited { text-decoration: none; color:#000; }
.navBtn:hover { text-decoration: none; color:#000; }
.navBtn:focus { text-decoration: none; color:#000; }
.navBtn:hover, .navBtn:active { text-decoration: none; color:#000; }

or this

 li a { text-decoration: none; color:#000; }
 li a:visited { text-decoration: none; color:#000; }
 li a:hover { text-decoration: none; color:#000; }
 li a:focus { text-decoration: none; color:#000; }
 li a:hover, .navBtn:active { text-decoration: none; color:#000; }

The content length is just a HTTP header. You cannot trust it. Just read everything you can from the stream.

Available is definitely wrong. It's just the number of bytes that can be read without blocking.

Another issue is your resource handling. Closing the stream has to happen in any case. try/catch/finally will do that.

Am adding this answer for the purpose of those who google about this..

There was an episode of DevBytes (ListView Cell Dragging and Rearranging) recently which explains how to do this

You can find it here also the sample code is available here.

What this code basically does is that it creates a dynamic listview by the extension of listview that supports cell dragging and swapping. So that you can use the DynamicListView instead of your basic ListView and that's it you have implemented a ListView with Drag and Drop.

Please note that in the following I'm comparing the Select approach (the one that the OP wants to avoid), with the Range approach (and this is the answer to the question). So don't stop reading when you see the first Select.

It really depends on what you are trying to do. Anyway, a simple example could be useful. Let's suppose that you want to set the value of the active cell to "foo". Using ActiveCell you would write something like this:

Sub Macro1()
    ActiveCell.Value = "foo"
End Sub

If you want to use it for a cell that is not the active one, for instance for "B2", you should select it first, like this:

Sub Macro2()
    Range("B2").Select
    Macro1
End Sub

Using Ranges you can write a more generic macro that can be used to set the value of any cell you want to whatever you want:

Sub SetValue(cellAddress As String, aVal As Variant)
    Range(cellAddress).Value = aVal
End Sub

Then you can rewrite Macro2 as:

Sub Macro2()
    SetCellValue "B2", "foo"
End Sub

And Macro1 as:

Sub Macro1()
    SetValue ActiveCell.Address, "foo"
End Sub

There is a new way to do this.

Android Studio 2.2 has APK Analyzer it will give lot of info about apk, checkout it here :- http://android-developers.blogspot.in/2016/05/android-studio-22-preview-new-ui.html

Better to use independent code.....

var xhrQueue = []; 

$(document).ajaxSend(function(event,jqxhr,settings){
    xhrQueue.push(jqxhr); //alert(settings.url);
});

$(document).ajaxComplete(function(event,jqxhr,settings){
    var i;   
    if((i=$.inArray(jqxhr,xhrQueue)) > -1){
        xhrQueue.splice(i,1); //alert("C:"+settings.url);
    }
});

ajaxAbort = function (){  //alert("abortStart");
    var i=0;
    while(xhrQueue.length){ 
        xhrQueue[i++] .abort(); //alert(i+":"+xhrQueue[i++]);
    }
};

Put anything into an array using Array.push().

var a=[], b={};
a.push(b);    
// a[0] === b;

Extra information on Arrays

Add more than one item at a time

var x = ['a'];
x.push('b', 'c');
// x = ['a', 'b', 'c']

Add items to the beginning of an array

var x = ['c', 'd'];
x.unshift('a', 'b');
// x = ['a', 'b', 'c', 'd']

Add the contents of one array to another

var x = ['a', 'b', 'c'];
var y = ['d', 'e', 'f'];
x.push.apply(x, y);
// x = ['a', 'b', 'c', 'd', 'e', 'f']
// y = ['d', 'e', 'f']  (remains unchanged)

Create a new array from the contents of two arrays

var x = ['a', 'b', 'c'];
var y = ['d', 'e', 'f'];
var z = x.concat(y);
// x = ['a', 'b', 'c']  (remains unchanged)
// y = ['d', 'e', 'f']  (remains unchanged)
// z = ['a', 'b', 'c', 'd', 'e', 'f']

In Mvc 4 you can use AcceptVerbsAttribute, I think this is a very clean solution

[AcceptVerbs(WebRequestMethods.Http.Get, WebRequestMethods.Http.Post)]
public IHttpActionResult Login()
{
   // Login logic
}

You must remember to use single quotes for char constants. So use

if (answer == 'y') return true;

Rather than

if (answer == "y") return true;

I tested this and it works

You can use DBMS_PIPE.SEND_MESSAGE with a message that is too large for the pipe, for example for a 5 second delay write XXX to a pipe that can only accept one byte using a 5 second timeout as below

dbms_pipe.pack_message('XXX');<br>
dummy:=dbms_pipe.send_message('TEST_PIPE', 5, 1);

But then that requires a grant for DBMS_PIPE so perhaps no better.

An HttpHandler (or IHttpHandler) is basically anything that is responsible for serving content. An ASP.NET page (aspx) is a type of handler.

You might write your own, for example, to serve images etc from a database rather than from the web-server itself, or to write a simple POX service (rather than SOAP/WCF/etc)

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

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

out array

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

The below code works fine but I am not sure about the radio button and dropdown list

$( '#form_id' ).submit( function( event ) {
    event.preventDefault();

    //validate fields
    var fail = false;
    var fail_log = '';
    var name;
    $( '#form_id' ).find( 'select, textarea, input' ).each(function(){
        if( ! $( this ).prop( 'required' )){

        } else {
            if ( ! $( this ).val() ) {
                fail = true;
                name = $( this ).attr( 'name' );
                fail_log += name + " is required \n";
            }

        }
    });

    //submit if fail never got set to true
    if ( ! fail ) {
        //process form here.
    } else {
        alert( fail_log );
    }

});

Regarding os.linesep:

Here is an exact unedited Python 2.7.1 interpreter session on Windows:

Python 2.7.1 (r271:86832, Nov 27 2010, 18:30:46) [MSC v.1500 32 bit (Intel)] on
win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import os
>>> os.linesep
'\r\n'
>>> f = open('myfile','w')
>>> f.write('hi there\n')
>>> f.write('hi there' + os.linesep) # same result as previous line ?????????
>>> f.close()
>>> open('myfile', 'rb').read()
'hi there\r\nhi there\r\r\n'
>>>

On Windows:

As expected, os.linesep does NOT produce the same outcome as '\n'. There is no way that it could produce the same outcome. 'hi there' + os.linesep is equivalent to 'hi there\r\n', which is NOT equivalent to 'hi there\n'.

It's this simple: use \n which will be translated automatically to os.linesep. And it's been that simple ever since the first port of Python to Windows.

There is no point in using os.linesep on non-Windows systems, and it produces wrong results on Windows.

DO NOT USE os.linesep!

I don't know this is the proper answer or not but it worked for me

Increase Gridle Wrapper Property

distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-all.zip

and Build Gridle to

    classpath 'com.android.tools.build:gradle:3.4.2'

its showing error because of the version.

To throw out another option, why not set the working directory (preferably via a script) to the desktop using setwd('C:\John\Desktop') and then read the files just using file names

The correct way to insert something (in Oracle) based on another record already existing is by using the MERGE statement.

Please note that this question has already been answered here on SO:

• oracle insert if row not exists
• insert if not exists oracle

You can group your specific layout under the correct folder structure as follows.

layout-land-target_version

ie

layout-land-19 // target KitKat

likewise you can create your layouts.

Hope this will help you

I faced something like that in one of the old and legacy projects that i worked in that not contains any interfaces or best practice and also it's too hard to enforce them build things again or refactoring the code due to the maturity of the project business, So in my UnitTest project i used to create a Wrapper over the classes that I want to mock and that wrapper implement interface which contains all my needed methods that I want to setup and work with, Now I can mock the wrapper instead of the real class.

For Example:

Service you want to test which not contains virtual methods or implement interface

public class ServiceA{

public void A(){}

public String B(){}

}

Wrapper to moq

public class ServiceAWrapper : IServiceAWrapper{

public void A(){}

public String B(){}

}

The Wrapper Interface

public interface IServiceAWrapper{

void A();

String B();

}

In the unit test you can now mock the wrapper:

    public void A_Run_ChangeStateOfX()
    {
    var moq = new Mock<IServiceAWrapper>();
    moq.Setup(...);
    }

This might be not the best practice, but if your project rules force you in this way, do it. Also Put all your Wrappers inside your Unit Test project or Helper project specified only for the unit tests in order to not overload the project with unneeded wrappers or adaptors.

Update: This answer from more than a year but in this year i faced a lot of similar scenarios with different solutions. For example it's so easy to use Microsoft Fake Framework to create mocks, fakes and stubs and even test private and protected methods without any interfaces. You can read: https://docs.microsoft.com/en-us/visualstudio/test/isolating-code-under-test-with-microsoft-fakes?view=vs-2017

The other possibility is using just numpy and it gives you the interior angle

import numpy as np

p0 = [3.5, 6.7]
p1 = [7.9, 8.4]
p2 = [10.8, 4.8]

''' 
compute angle (in degrees) for p0p1p2 corner
Inputs:
    p0,p1,p2 - points in the form of [x,y]
'''

v0 = np.array(p0) - np.array(p1)
v1 = np.array(p2) - np.array(p1)

angle = np.math.atan2(np.linalg.det([v0,v1]),np.dot(v0,v1))
print np.degrees(angle)

and here is the output:

In [2]: p0, p1, p2 = [3.5, 6.7], [7.9, 8.4], [10.8, 4.8]

In [3]: v0 = np.array(p0) - np.array(p1)

In [4]: v1 = np.array(p2) - np.array(p1)

In [5]: v0
Out[5]: array([-4.4, -1.7])

In [6]: v1
Out[6]: array([ 2.9, -3.6])

In [7]: angle = np.math.atan2(np.linalg.det([v0,v1]),np.dot(v0,v1))

In [8]: angle
Out[8]: 1.8802197318858924

In [9]: np.degrees(angle)
Out[9]: 107.72865519428085

You can directly specify the item's alignment, for example:

textright: {    
  alignSelf: 'flex-end',  
},

This is a function that zips a whole folder and its contents in to a zip file and you can use it simple like this :

addzip ("path/folder/" , "/path2/folder.zip" );

function :

// compress all files in the source directory to destination directory 
    function create_zip($files = array(), $dest = '', $overwrite = false) {
    if (file_exists($dest) && !$overwrite) {
        return false;
    }
    if (($files)) {
        $zip = new ZipArchive();
        if ($zip->open($dest, $overwrite ? ZIPARCHIVE::OVERWRITE : ZIPARCHIVE::CREATE) !== true) {
            return false;
        }
        foreach ($files as $file) {
            $zip->addFile($file, $file);
        }
        $zip->close();
        return file_exists($dest);
    } else {
        return false;
    }
}

function addzip($source, $destination) {
    $files_to_zip = glob($source . '/*');
    create_zip($files_to_zip, $destination);
    echo "done";
}

        // JB: Or ... can it!?
        var $el = $(elem);
        var insertionFn = 'after';
        var $insertionPoint = $el.prev();
        if (!$insertionPoint.length) {
            insertionFn = 'prepend';
            $insertionPoint = $el.parent();
        }

        $el.detach().attr('type', value);
        $insertionPoint[insertionFn]($el);
        return value;

    } else if (!jQuery.support.radioValue && value === "radio" && jQuery.nodeName(elem, "input")) {
        // Setting the type on a radio button after the value resets the value in IE6-9
        // Reset value to it's default in case type is set after value
        // This is for element creation
        var val = elem.value;
        elem.setAttribute("type", value);
        if (val) {
            elem.value = val;
        }
        return value;
    }
}

It gets around the issue by removing the input from the document, changing the type and then putting it back where it was originally.

Note that this snippet was only tested for WebKit browsers – no guarantees on anything else!

With that row

var element = {};

you define element to be a plain object. The native JavaScript object has no push() method. To add new items to a plain object use this syntax:

element[ yourKey ] = yourValue;

On the other hand you could define element as an array using

var element = [];

Then you can add elements using push().

Javascript variables are not typed, so f can be assigned an integer value even though it's been assigned through boolean operators.

f is assigned the nearest value that is not equivalent to false. So 0, false, null, undefined, are all passed over:

alert(null || undefined || false || '' || 0 || 4 || 'bar'); // alerts '4'

You can use WScript.ScriptFullName which will return the full path of the executing script.

You can then use string manipulation (jscript example) :

scriptdir = WScript.ScriptFullName.substring(0,WScript.ScriptFullName.lastIndexOf(WScript.ScriptName)-1)

Or get help from FileSystemObject, (vbscript example) :

scriptdir = CreateObject("Scripting.FileSystemObject").GetParentFolderName(WScript.ScriptFullName)

There is nothing wrong with your code. It's the NBC.com doing tricks on you. When NBC.com decides that your browser is not capable of displaying PDF, it simply sends back a webpage regardless what you are requesting, even if it doesn't exist.

You need to trick it back by telling it your browser is capable, something like,

conn.setRequestProperty("User-Agent",
    "Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9.0.13) Gecko/2009073021 Firefox/3.0.13");

My problem was in wrong configuration of myproject.csproj file. '_address-step1-stored.cshtml' file did not copy on publish. 'None' changed to 'Content', now it's ok.

You can directly cast it:

enum MyMonthEnum { January = 1, February, March, April, May, June, July, August, September, October, November, December };

public static string GetMyMonthName(int MonthIndex)
{
  MyMonthEnum MonthName = (MyMonthEnum)MonthIndex;
  return MonthName.ToString();
}

For Example:

string MySelectedMonthName=GetMyMonthName(8);
 //then MySelectedMonthName value will be August.

Leaving another way here

git branch newbranch
git checkout master 
git merge newbranch 

Try this

Get-ChildItem  | % { Write-Host "$($_.FullName)\$buildConfig\$($_.Name).dll" }

In your code,

1. $build-Config is not a valid variable name.
2. $.FullName should be $_.FullName
3. $ should be $_.Name

c:

int roundUp(int numToRound, int multiple)
{
  return (multiple ? (((numToRound+multiple-1) / multiple) * multiple) : numToRound);
}

and for your ~/.bashrc:

roundup()
{
  echo $(( ${2} ? ((${1}+${2}-1)/${2})*${2} : ${1} ))
}

gdb has --init-command <somefile> where somefile has a list of gdb commands to run, I use this to have //GDB comments in my code, then `

echo "file ./a.out" > run
grep -nrIH "//GDB"|
    sed "s/\(^[^:]\+:[^:]\+\):.*$/\1/g" |
    awk '{print "b" " " $1}'|
    grep -v $(echo $0|sed "s/.*\///g") >> run
gdb --init-command ./run -ex=r

as a script, which puts the command to load the debug symbols, and then generates a list of break commands to put a break point for each //GDB comment, and starts it running

Here's a different approach. The heart of it was created by turning on the Macro Recorder and filtering the columns per your specifications. Then there's a bit of code to copy the results. It will run faster than looping through each row and column:

Sub FilterAndCopy()
Dim LastRow As Long

Sheets("Sheet2").UsedRange.Offset(0).ClearContents
With Worksheets("Sheet1")
    .Range("$A:$E").AutoFilter
    .Range("$A:$E").AutoFilter field:=1, Criteria1:="#N/A"
    .Range("$A:$E").AutoFilter field:=2, Criteria1:="=String1", Operator:=xlOr, Criteria2:="=string2"
    .Range("$A:$E").AutoFilter field:=3, Criteria1:=">0"
    .Range("$A:$E").AutoFilter field:=5, Criteria1:="Number"
    LastRow = .Range("A" & .Rows.Count).End(xlUp).Row
    .Range("A1:A" & LastRow).SpecialCells(xlCellTypeVisible).EntireRow.Copy _
            Destination:=Sheets("Sheet2").Range("A1")
End With
End Sub

As a side note, your code has more loops and counter variables than necessary. You wouldn't need to loop through the columns, just through the rows. You'd then check the various cells of interest in that row, much like you did.

With Xcode 7.2.1, if you are certain that your provisioning profile is correct (it has the correct App ID and certificate, and the corresponding certificate exists in your Keychain Access) then set the Code Signing Identity and set the Provisioning Profile to Automatic.

when I send only one object from the client to server all works well.

when I attempt to send several objects one after another on the same stream I get StreamCorruptedException.

Actually, your client code is writing one object to the server and reading multiple objects from the server. And there is nothing on the server side that is writing the objects that the client is trying to read.

I would suggest:

std::cout << setbase(16) << 32;

(\d+)\s+(\(.*?\))?\s?Z

Note the escaped parentheses, and the ? (zero or once) quantifiers. Any of the groups you don't want to capture can be (?: non-capture groups).

I agree about the spaces. \s is a better option there. I also changed the quantifier to insure there are digits at the beginning. As far as newlines, that would depend on context: if the file is parsed line by line it won't be a problem. Another option is to anchor the start and end of the line (add a ^ at the front and a $ at the end).

This can happen for more than one reason. In my case this happened due to a permissions issue. The user that the task was running as didn't have permission to write to the logs directory so it failed with this error.

You're talking about template literals.

They allow for both multiline strings and string interpolation.

Multiline strings:

console.log(`foo_x000D_
bar`);_x000D_
// foo_x000D_
// bar

String interpolation:

var foo = 'bar';_x000D_
console.log(`Let's meet at the ${foo}`);_x000D_
// Let's meet at the bar

Try using

Dir.glob(".") 

To see what's in the directory (and therefore what directory it's looking at).
