You can use the OpenSSL Command line tool. The following commands should do the trick

openssl pkcs12 -in client_ssl.pfx -out client_ssl.pem -clcerts

openssl pkcs12 -in client_ssl.pfx -out root.pem -cacerts

If you want your file to be password protected etc, then there are additional options.

You can read the entire documentation here.

I got the same error. In my case, I tried all of the above, but I couldn't get the result.

I finally realized that in my case, the reason for the error was that the certificate password was not entered or entered incorrectly. The error disappeared when I entered the password dynamically correctly. successful

openssl rsa -in f.pem -inform PEM -out f.der -outform DER

For simple things, I just use the XmlDocument/XmlNode/XmlAttribute classes and XmlDocument DOM found in System.XML.

It generates the XML for me, I just need to link a few items together.

However, on larger things, I use XML serialization.

Just had a look at the DOM (document.scripts[1].attributes) of this page that uses google analytics. I can tell you that google is using async="".

[type="text/javascript", async="", src="http://www.google-analytics.com/ga.js"]

In real life you wish to simulate a signal with white noise. You should add to your signal random points that have Normal Gaussian distribution. If we speak about a device that have sensitivity given in unit/SQRT(Hz) then you need to devise standard deviation of your points from it. Here I give function "white_noise" that does this for you, an the rest of a code is demonstration and check if it does what it should.

%matplotlib inline
import numpy as np
import matplotlib.pyplot as plt
from scipy import signal

"""
parameters: 
rhp - spectral noise density unit/SQRT(Hz)
sr  - sample rate
n   - no of points
mu  - mean value, optional

returns:
n points of noise signal with spectral noise density of rho
"""
def white_noise(rho, sr, n, mu=0):
    sigma = rho * np.sqrt(sr/2)
    noise = np.random.normal(mu, sigma, n)
    return noise

rho = 1 
sr = 1000
n = 1000
period = n/sr
time = np.linspace(0, period, n)
signal_pure = 100*np.sin(2*np.pi*13*time)
noise = white_noise(rho, sr, n)
signal_with_noise = signal_pure + noise

f, psd = signal.periodogram(signal_with_noise, sr)

print("Mean spectral noise density = ",np.sqrt(np.mean(psd[50:])), "arb.u/SQRT(Hz)")

plt.plot(time, signal_with_noise)
plt.plot(time, signal_pure)
plt.xlabel("time (s)")
plt.ylabel("signal (arb.u.)")
plt.show()

plt.semilogy(f[1:], np.sqrt(psd[1:]))
plt.xlabel("frequency (Hz)")
plt.ylabel("psd (arb.u./SQRT(Hz))")
#plt.axvline(13, ls="dashed", color="g")
plt.axhline(rho, ls="dashed", color="r")
plt.show()

One more alternative:

git name-rev --name-only HEAD

You may try CScope + tceetree + Graphviz.

The following will return '0' if the string consists entirely of zeros:

CASE WHEN SUBSTRING(str_col, PATINDEX('%[^0]%', str_col+'.'), LEN(str_col)) = '' THEN '0' ELSE SUBSTRING(str_col, PATINDEX('%[^0]%', str_col+'.'), LEN(str_col)) END AS str_col

Swift 2.0

It seems that Swift 2.0 has actually introduced the String(data:encoding:) as an String extension when you import Foundation. I haven't found any place where this is documented, weirdly enough.

(pre Swift 2.0) Lightweight extension

Here's a copy-pasteable little extension without using NSString, let's cut the middle-man.

import Foundation

extension NSData
{
    var byteBuffer : UnsafeBufferPointer<UInt8> { get { return UnsafeBufferPointer<UInt8>(start: UnsafeMutablePointer<UInt8>(self.bytes), count: self.length) }}
}

extension String
{
    init?(data : NSData, encoding : NSStringEncoding)
    {
        self.init(bytes: data.byteBuffer, encoding: encoding)
    }
}

// Playground test
let original = "Nymphs blitz quick vex dwarf jog"
let encoding = NSASCIIStringEncoding

if let data = original.dataUsingEncoding(encoding)
{
    String(data: data, encoding: encoding)
}

This also give you access to data.byteBuffer which is a sequence type, so all those cool operations you can do with sequences also work, like doing a reduce { $0 &+ $1 } for a checksum.

Notes

In my previous edit, I used this method:

var buffer = Array<UInt8>(count: data.length, repeatedValue: 0x00)
data.getBytes(&buffer, length: data.length)
self.init(bytes: buffer, encoding: encoding)

The problem with this approach, is that I'm creating a copy of the information into a new array, thus, I'm duplicating the amount of bytes (specifically: encoding size * data.length)

In your widget's Info.plist file, don't forget to set your AllowNetworkAccess key to true.

It looks like the machine you're trying to run this on has only 256 MB memory.

Maybe the JVM tries to allocate a large, contiguous block of 64 MB memory. The 192 MB that you have free might be fragmented into smaller pieces, so that there is no contiguous block of 64 MB free to allocate.

Try starting your Java program with a smaller heap size, for example:

java -Xms16m ...

To create all intermediate-level destination directories you could use os.makedirs() before copying:

import os
import shutil

srcfile = 'a/long/long/path/to/file.py'
dstroot = '/home/myhome/new_folder'


assert not os.path.isabs(srcfile)
dstdir =  os.path.join(dstroot, os.path.dirname(srcfile))

os.makedirs(dstdir) # create all directories, raise an error if it already exists
shutil.copy(srcfile, dstdir)

Put it this way

where ("R"."TIME_STAMP">=TO_DATE ('03-02-2013 00:00:00', 'DD-MM-YYYY HH24:MI:SS')
   AND "R"."TIME_STAMP"<=TO_DATE ('09-02-2013 23:59:59', 'DD-MM-YYYY HH24:MI:SS')) 

Where R is table name.
TIME_STAMP is FieldName in Table R.

PHPSESSID is an auto generated session cookie by the server which contains a random long number which is given out by the server itself

While the built-in libs for XML parsing are quite good I am partial to lxml.

But for parsing RSS feeds, I'd recommend Universal Feed Parser, which can also parse Atom. Its main advantage is that it can digest even most malformed feeds.

Python 2.6 already includes a JSON parser, but a newer version with improved speed is available as simplejson.

With these tools building your app shouldn't be that difficult.

One thing to point out is that foreach skips uninitialized values while map does not.

var arr = [1, , 3];

arr.forEach(function(element) {
    console.log(element);
});
//Expected output: 1 3

console.log(arr.map(element => element));
//Expected output: [1, undefined, 3];

name = ( (city.getName() == null)? "N/A" : city.getName() );

firstly the condition (city.getName() == null) is checked. If yes, then "N/A" is assigned to name or simply name="N/A" or else the value from city.getName() is assigned to name, i.e. name=city.getName().

Things to look out here:

1. condition is in the parenthesis followed by a question mark. That's why I write (city.getName() == null)?. Here the question mark is right after the condition. Easy to see/read/guess even!
2. value left of colon (:) and value right of colon (a) value left of colon is assigned when condition is true, else the value right of colon is assigned to the variable.

Sorry to open an old thread but I'm posting just in case it helps someone. This seems to be the easiest way to do this in Python 3.

from datetime import datetime

Date = str(datetime.now())[:10]
Hour = str(datetime.now())[11:13]
Minute = str(datetime.now())[14:16]
Second = str(datetime.now())[17:19]
Millisecond = str(datetime.now())[20:]

If you need the values as a number just cast them as an int e.g

Hour = int(str(datetime.now())[11:13])

What about trying the easiest and probably most effective approach? The method normalize() removes all the rightmost trailing zeros.

from decimal import Decimal

print (Decimal('0.001000').normalize())
# Result: 0.001

Works in Python 2 and Python 3.

-- Updated --

The only problem as @BobStein-VisiBone pointed out, is that numbers like 10, 100, 1000... will be displayed in exponential representation. This can be easily fixed using the following function instead:

from decimal import Decimal


def format_float(f):
    d = Decimal(str(f));
    return d.quantize(Decimal(1)) if d == d.to_integral() else d.normalize()

Instructions

Things You'll Need

• Proficiency in C++
• C++ compiler
• Debugger and other investigative software tools

1

Understand the operator basics. The C++ operator new allocates heap memory. The delete operator frees heap memory. For every new, you should use a delete so that you free the same memory you allocated:

char* str = new char [30]; // Allocate 30 bytes to house a string.

delete [] str; // Clear those 30 bytes and make str point nowhere.

2

Reallocate memory only if you've deleted. In the code below, str acquires a new address with the second allocation. The first address is lost irretrievably, and so are the 30 bytes that it pointed to. Now they're impossible to free, and you have a memory leak:

char* str = new char [30]; // Give str a memory address.

// delete [] str; // Remove the first comment marking in this line to correct.

str = new char [60]; /* Give str another memory address with
                                                    the first one gone forever.*/

delete [] str; // This deletes the 60 bytes, not just the first 30.

3

Watch those pointer assignments. Every dynamic variable (allocated memory on the heap) needs to be associated with a pointer. When a dynamic variable becomes disassociated from its pointer(s), it becomes impossible to erase. Again, this results in a memory leak:

char* str1 = new char [30];

char* str2 = new char [40];

strcpy(str1, "Memory leak");

str2 = str1; // Bad! Now the 40 bytes are impossible to free.

delete [] str2; // This deletes the 30 bytes.

delete [] str1; // Possible access violation. What a disaster!

4

Be careful with local pointers. A pointer you declare in a function is allocated on the stack, but the dynamic variable it points to is allocated on the heap. If you don't delete it, it will persist after the program exits from the function:

void Leak(int x){

char* p = new char [x];

// delete [] p; // Remove the first comment marking to correct.

}

5

Pay attention to the square braces after "delete." Use delete by itself to free a single object. Use delete [] with square brackets to free a heap array. Don't do something like this:

char* one = new char;

delete [] one; // Wrong

char* many = new char [30];

delete many; // Wrong!

6

If the leak yet allowed - I'm usually seeking it with deleaker (check it here: http://deleaker.com).

Insert all n elements from an array to BST takes O(n logn). n elemnts in an array can be inserted to a heap in O(n) time. Which gives heap a definite advantage

About the Count() method, if the IEnumarable is an ICollection, then we can't iterate across all items because we can retrieve the Count field of ICollection, if the IEnumerable is not an ICollection we must iterate across all items using a while with a MoveNext, take a look the .NET Framework Code:

public static int Count<TSource>(this IEnumerable<TSource> source)
{
    if (source == null) 
        throw Error.ArgumentNull("source");

    ICollection<TSource> collectionoft = source as ICollection<TSource>;
    if (collectionoft != null) 
        return collectionoft.Count;

    ICollection collection = source as ICollection;
    if (collection != null) 
        return collection.Count;

    int count = 0;
    using (IEnumerator<TSource> e = source.GetEnumerator())
    {
        checked
        {
            while (e.MoveNext()) count++;
        }
    }
    return count;
}

Reference: Reference Source Enumerable

You can also put the item with the default value selected out of the ng-repeat like follow :

<div ng-app="app" ng-controller="myCtrl">
    <select class="form-control" ng-change="unitChanged()" ng-model="data.unit">
        <option value="yourDefaultValue">Default one</option>
        <option ng-selected="data.unit == item.id" ng-repeat="item in units" ng-value="item.id">{{item.label}}</option>
    </select>
</div>

and don't forget the value atribute if you leave it blank you will have the same issue.

Use /config.php.

You can use the semver package to determine if a version satisfies a semantic version requirement. This is not the same as comparing two actual versions, but is a type of comparison.

For example, version 3.6.0+1234 should be the same as 3.6.0.

import semver
semver.match('3.6.0+1234', '==3.6.0')
# True

from packaging import version
version.parse('3.6.0+1234') == version.parse('3.6.0')
# False

from distutils.version import LooseVersion
LooseVersion('3.6.0+1234') == LooseVersion('3.6.0')
# False

Tried many things but found solution by added below line in my.ini and restarting mysql service.

innodb_strict_mode = 0

Just wanted to summarize everything:

.unselectable {
  -webkit-touch-callout: none;
  -webkit-user-select: none;
  -khtml-user-select: none;
  -moz-user-select: none;
  -ms-user-select: none;
  user-select: none;
}

<div class="unselectable" unselectable="yes" onselectstart="return false;"/>

Both methods have their problems.

If the subclass changes the identity, then you need to compare their actual classes. Otherwise, you violate the symmetric property. For instance, different types of Persons should not be considered equivalent, even if they have the same name.

However, some subclasses don't change identity and these need to use instanceof. For instance, if we have a bunch of immutable Shape objects, then a Rectangle with length and width of 1 should be equal to the unit Square.

In practice, I think the former case is more likely to be true. Usually, subclassing is a fundamental part of your identity and being exactly like your parent except you can do one little thing does not make you equal.

You can use below SQL to read the BLOB Fields from table.

SELECT DBMS_LOB.SUBSTR(BLOB_FIELD_NAME) FROM TABLE_NAME;

$('input[type=button]' ).click(function() {
   var bid = jQuery(this).attr('id'); // button ID 
   var trid = $(this).parents('tr:first').attr('id'); // table row ID 
 });

I like the one from HPP comment, it can be used anywhere without any parameter:

new Handler(Looper.getMainLooper()).post(new Runnable() {
    @Override
    public void run() {
        Log.d("UI thread", "I am the UI thread");
    }
});

Yes, you can split a string out onto multiple lines without introducing newlines into the actual string, but it aint pretty:

string s = $@"This string{
string.Empty} contains no newlines{
string.Empty} even though it is spread onto{
string.Empty} multiple lines.";

The trick is to introduce code that evaluates to empty, and that code may contain newlines without affecting the output. I adapted this approach from this answer to a similar question.

There is apparently some confusion as to what the question is, but there are two hints that what we want here is a string literal not containing any newline characters, whose definition spans multiple lines. (in the comments he says so, and "here's what I have" shows code that does not create a string with newlines in it)

This unit test shows the intent:

    [TestMethod]
    public void StringLiteralDoesNotContainSpaces()
    {
        string query = "hi"
                     + "there";
        Assert.AreEqual("hithere", query);
    }

Change the above definition of query so that it is one string literal, instead of the concatenation of two string literals which may or may not be optimized into one by the compiler.

The C++ approach would be to end each line with a backslash, causing the newline character to be escaped and not appear in the output. Unfortunately, there is still then the issue that each line after the first must be left aligned in order to not add additional whitespace to the result.

There is only one option that does not rely on compiler optimizations that might not happen, which is to put your definition on one line. If you want to rely on compiler optimizations, the + you already have is great; you don't have to left-align the string, you don't get newlines in the result, and it's just one operation, no function calls, to expect optimization on.

<?php

$nothing = NULL;
$something = '';
$array = array(1,2,3);

// Create a function that checks if a variable is set or empty, and display "$variable_name is SET|EMPTY"
function  check($var) {
    if (isset($var)) {
        echo 'Variable is SET'. PHP_EOL;
  } elseif (empty($var)) { 
        echo 'Variable is empty' . PHP_EOL;

   } 

} 

check($nothing);
check($something);
check($array);

This is how the JDK does it (adapted from OpenJDK 8, String.java/regionMatches):

static boolean charactersEqualIgnoringCase(char c1, char c2) {
  if (c1 == c2) return true;

  // If characters don't match but case may be ignored,
  // try converting both characters to uppercase.
  char u1 = Character.toUpperCase(c1);
  char u2 = Character.toUpperCase(c2);
  if (u1 == u2) return true;

  // Unfortunately, conversion to uppercase does not work properly
  // for the Georgian alphabet, which has strange rules about case
  // conversion.  So we need to make one last check before
  // exiting.
  return Character.toLowerCase(u1) == Character.toLowerCase(u2);
}

I suppose that works for Turkish too.

<form id="myForm">
<select id="selectNumber">
    <option>Choose a number</option>
    <script>
        var myArray = new Array("1", "2", "3", "4", "5" . . . . . "N");
        for(i=0; i<myArray.length; i++) {  
            document.write('<option value="' + myArray[i] +'">' + myArray[i] + '</option>');
        }
    </script>
</select>
</form>

@ian this is not 100% accurate. If you have several iframes in a page you will have multiple onPageFinished (and onPageStarted). And if you have several redirects it may also fail. This approach solves (almost) all the problems:

boolean loadingFinished = true;
boolean redirect = false;

mWebView.setWebViewClient(new WebViewClient() {

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String urlNewString) {
        if (!loadingFinished) {
            redirect = true;
        }

        loadingFinished = false;
        webView.loadUrl(urlNewString);
        return true;
    }

    @Override
    public void onPageStarted(WebView view, String url) {
        loadingFinished = false;
        //SHOW LOADING IF IT ISNT ALREADY VISIBLE  
    }

    @Override
    public void onPageFinished(WebView view, String url) {
        if (!redirect) {
           loadingFinished = true;
            //HIDE LOADING IT HAS FINISHED
        } else {
            redirect = false; 
        }
    }
});

UPDATE:

According to the documentation: onPageStarted will NOT be called when the contents of an embedded frame changes, i.e. clicking a link whose target is an iframe.

I found a specific case like that on Twitter where only a pageFinished was called and messed the logic a bit. To solve that I added a scheduled task to remove loading after X seconds. This is not needed in all the other cases.

UPDATE 2:

Now with current Android WebView implementation:

boolean loadingFinished = true;
boolean redirect = false;

    mWebView.setWebViewClient(new WebViewClient() {

        @Override
        public boolean shouldOverrideUrlLoading(
                WebView view, WebResourceRequest request) {
            if (!loadingFinished) {
               redirect = true;
            }

            loadingFinished = false;
            webView.loadUrl(request.getUrl().toString());
            return true;
        }

        @Override
        public void onPageStarted(
                WebView view, String url, Bitmap favicon) {
            super.onPageStarted(view, url, favicon);
            loadingFinished = false;
            //SHOW LOADING IF IT ISNT ALREADY VISIBLE  
        }

        @Override
        public void onPageFinished(WebView view, String url) {
            if (!redirect) {
               loadingFinished = true;
                //HIDE LOADING IT HAS FINISHED
            } else {
                redirect = false; 
            }
        }
    });

Change string[] lines = File.ReadLines("c:\\file.txt"); to IEnumerable<string> lines = File.ReadLines("c:\\file.txt"); The rest of your code should work fine.

Actually I found this more helpful for functions that return IAsyncAction.

            var task = asyncFunction();
            while (task.Status == AsyncStatus.Completed) ;

For what is worth if anyone should read again this topic(like me) the correct answer would be in DateTimeFormatter definition, e.g.:

private static DateTimeFormatter DATE_FORMAT =  
            new DateTimeFormatterBuilder().appendPattern("dd/MM/yyyy[ [HH][:mm][:ss][.SSS]]")
            .parseDefaulting(ChronoField.HOUR_OF_DAY, 0)
            .parseDefaulting(ChronoField.MINUTE_OF_HOUR, 0)
            .parseDefaulting(ChronoField.SECOND_OF_MINUTE, 0)
            .toFormatter(); 

One should set the optional fields if they will appear. And the rest of code should be exactly the same.

I have encountered the exception java.lang.IllegalArgumentException: Unknown URI: content://downloads/public_downloads/7505 in getting the doucument from the downloads. This solution worked for me.

else if (isDownloadsDocument(uri)) {
            String fileName = getFilePath(context, uri);
            if (fileName != null) {
                return Environment.getExternalStorageDirectory().toString() + "/Download/" + fileName;
            }

            String id = DocumentsContract.getDocumentId(uri);
            if (id.startsWith("raw:")) {
                id = id.replaceFirst("raw:", "");
                File file = new File(id);
                if (file.exists())
                    return id;
            }

            final Uri contentUri = ContentUris.withAppendedId(Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
            return getDataColumn(context, contentUri, null, null);
        }

This the method used to get the filepath

   public static String getFilePath(Context context, Uri uri) {

    Cursor cursor = null;
    final String[] projection = {
            MediaStore.MediaColumns.DISPLAY_NAME
    };

    try {
        cursor = context.getContentResolver().query(uri, projection, null, null,
                null);
        if (cursor != null && cursor.moveToFirst()) {
            final int index = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DISPLAY_NAME);
            return cursor.getString(index);
        }
    } finally {
        if (cursor != null)
            cursor.close();
    }
    return null;
}

git has a 4G (32bit) limit for repo.

You want options(warn=-1). However, note that warn=0 is not the safest warning level and it should not be assumed as the current one, particularly within scripts or functions. Thus the safest way to temporary turn off warnings is:

oldw <- getOption("warn")
options(warn = -1)

[your "silenced" code]

options(warn = oldw)

From my perspective, we could break down common code debugging tasks into three distinct usage patterns:

1. Something has raised an exception: runserver_plus' Werkzeug debugger to the rescue. The ability to run custom code at all the trace levels is a killer. And if you're completely stuck, you can create a Gist to share with just a click.
2. Page is rendered, but the result is wrong: again, Werkzeug rocks. To make a breakpoint in code, just type assert False in the place you want to stop at.
3. Code works wrong, but the quick look doesn't help. Most probably, an algorithmic problem. Sigh. Then I usually fire up a console debugger PuDB: import pudb; pudb.set_trace(). The main advantage over [i]pdb is that PuDB (while looking as you're in 80's) makes setting custom watch expressions a breeze. And debugging a bunch of nested loops is much simpler with a GUI.

Ah, yes, the templates' woes. The most common (to me and my colleagues) problem is a wrong context: either you don't have a variable, or your variable doesn't have some attribute. If you're using debug toolbar, just inspect the context at the "Templates" section, or, if it's not sufficient, set a break in your views' code just after your context is filled up.

So it goes.

You may be forgetting something. Before #include <iostream>, write #include <stdafx.h> and maybe that will help. Then, when you are done writing, click test, than click output from build, then when it is done processing/compiling, press Ctrl+F5 to open the Command Prompt and it should have the output and "press any key to continue."

Adding to the above. You use the Dispatch timer if you want the tick events marshalled back to the UI thread. Otherwise I would use System.Timers.Timer.

Lock-based concurrency control

Using locking for controlling access to shared resources is prone to deadlocks, and the transaction scheduler alone cannot prevent their occurrences.

For instance, relational database systems use various locks to guarantee transaction ACID properties.

No matter what relational database system you are using, locks will always be acquired when modifying (e.g., UPDATE or DELETE) a certain table record. Without locking a row that was modified by a currently running transaction, Atomicity would be compromised).

What is a deadlock

A deadlock happens when two concurrent transactions cannot make progress because each one waits for the other to release a lock, as illustrated in the following diagram.

Because both transactions are in the lock acquisition phase, neither one releases a lock prior to acquiring the next one.

Recovering from a deadlock situation

If you're using a Concurrency Control algorithm that relies on locks, then there is always the risk of running into a deadlock situation. Deadlocks can occur in any concurrency environment, not just in a database system.

For instance, a multithreading program can deadlock if two or more threads are waiting on locks that were previously acquired so that no thread can make any progress. If this happens in a Java application, the JVM cannot just force a Thread to stop its execution and release its locks.

Even if the Thread class exposes a stop method, that method has been deprecated since Java 1.1 because it can cause objects to be left in an inconsistent state after a thread is stopped. Instead, Java defines an interrupt method, which acts as a hint as a thread that gets interrupted can simply ignore the interruption and continue its execution.

For this reason, a Java application cannot recover from a deadlock situation, and it is the responsibility of the application developer to order the lock acquisition requests in such a way that deadlocks can never occur.

However, a database system cannot enforce a given lock acquisition order since it's impossible to foresee what other locks a certain transaction will want to acquire further. Preserving the lock order becomes the responsibility of the data access layer, and the database can only assist in recovering from a deadlock situation.

The database engine runs a separate process that scans the current conflict graph for lock-wait cycles (which are caused by deadlocks). When a cycle is detected, the database engine picks one transaction and aborts it, causing its locks to be released, so that the other transaction can make progress.

Unlike the JVM, a database transaction is designed as an atomic unit of work. Hence, a rollback leaves the database in a consistent state.

I had the same error. What worked for me is when you go for the SMSS GUI option, look at General, Files in Options settings. After I did that (replace DB, set location) all went well.

when you return some thing, the code exits out of the loop with what ever you are returning.so, in your code, in the first iteration, name is "one". so, as soon as it reaches return new Text(name), code exits the loop with return new Text("one"). so, try to print it or use asynchronous returns.

In modern browsers, this has become a lot easier, thanks to the URLSearchParams interface. This defines a host of utility methods to work with the query string of a URL.

Assuming that our URL is https://example.com/?product=shirt&color=blue&newuser&size=m, you can grab the query string using window.location.search:

const queryString = window.location.search;
console.log(queryString);
// ?product=shirt&color=blue&newuser&size=m

You can then parse the query string’s parameters using URLSearchParams:

const urlParams = new URLSearchParams(queryString);

Then you can call any of its methods on the result.

For example, URLSearchParams.get() will return the first value associated with the given search parameter:

const product = urlParams.get('product')
console.log(product);
// shirt

const color = urlParams.get('color')
console.log(color);
// blue

const newUser = urlParams.get('newuser')
console.log(newUser);
// empty string

You can use URLSearchParams.has() to check whether a certain parameter exists:

console.log(urlParams.has('product'));
// true

console.log(urlParams.has('paymentmethod'));
// false

For further reading please click here.

preg_replace('/[^a-zA-Z0-9_ \-()\/%-&]/s', '', $String);

// will return the host name and port
var host = window.location.host; 

or possibly

var host = window.location.protocol + "//" + window.location.host;

or if you like concatenation

var protocol = location.protocol;
var slashes = protocol.concat("//");
var host = slashes.concat(window.location.host);

// or as you probably should do
var host = location.protocol.concat("//").concat(window.location.host);

// the above is the same as origin, e.g. "https://stackoverflow.com"
var host = window.location.origin;

If you have or expect custom ports use window.location.host instead of window.location.hostname

There are multiple rows with the same date, but the time is different. Therefore, DISTINCT start_date will not work. What you need is: cast the start_date to a DATE (so the TIME part is gone), and then do a DISTINCT:

SELECT DISTINCT CAST(start_date AS DATE) FROM table;

Depending on what database you use, the type name for DATE is different.

With zsh you can do this:

% cat infile 
tar
more than one word
gz
java
gz
java
tar
class
class
zsh-5.0.0[t]% print -l "${(fu)$(<infile)}"
tar
more than one word
gz
java
class

Or you can use AWK:

% awk '!_[$0]++' infile    
tar
more than one word
gz
java
class

The problem is your query returned false meaning there was an error in your query. After your query you could do the following:

if (!$result) {
    die(mysqli_error($link));
}

Or you could combine it with your query:

$results = mysqli_query($link, $query) or die(mysqli_error($link));

That will print out your error.

Also... you need to sanitize your input. You can't just take user input and put that into a query. Try this:

$query = "SELECT * FROM shopsy_db WHERE name LIKE '%" . mysqli_real_escape_string($link, $searchTerm) . "%'";

In reply to: Table 'sookehhh_shopsy_db.sookehhh_shopsy_db' doesn't exist

Are you sure the table name is sookehhh_shopsy_db? maybe it's really like users or something.

The accepted answer implies this, but I'd like to make explicit the connection to shell builtins:

As mentioned already, export will make a variable available to both the shell and children. If export is not used, the variable will only be available in the shell, and only shell builtins can access it.

That is,

tango=3
env | grep tango # prints nothing, since env is a child process
set | grep tango # prints tango=3 - "type set" shows `set` is a shell builtin

I tried all the above no good. So I just add a padding individually:

 #button {

    font-size: 20px;
    color: white;
    background: crimson;
    border: 2px solid rgb(37, 34, 34);
    border-radius: 10px;
    padding-top: 10px;
    padding-bottom: 10px;
    padding-right: 10px;
    padding-left: 10px;
 }

In fact when you open the pom.xml, you should see 5 tabs in the bottom. Click the pom.xml, and you can type whatever dependencies you want.

Instead of downloading separate java files as suggested by Veer, you could just add this JAR file to your package.

To add the jar file to your project in Eclipse, do the following:

1. Right click on your project, click Build Path > Configure Build Path
2. Goto Libraries tab > Add External JARs
3. Locate the JAR file and add

I had this problem in a DataFrame (df) created from an Excel-sheet with several internal header rows.

After cleaning out the internal header rows from df, the columns' values were of "non-null object" type (DataFrame.info()).

This code converted all numerical values of multiple columns to int64 and float64 in one go:

for i in range(0, len(df.columns)):
    df.iloc[:,i] = pd.to_numeric(df.iloc[:,i], errors='ignore')
    # errors='ignore' lets strings remain as 'non-null objects'

Use ARRAY_AGG function for PostgreSQL, U-SQL, IBM DB2, and Google BigQuery SQL:

SELECT customer, (ARRAY_AGG(id ORDER BY total DESC))[1], MAX(total)
FROM purchases
GROUP BY customer

// timestamp to Date
long timestamp = 5607059900000; //Example -> in ms
Date d = new Date(timestamp );

// Date to timestamp
long timestamp = d.getTime();

//If you want the current timestamp :
Calendar c = Calendar.getInstance();
long timestamp = c.getTimeInMillis();

javascript fade to white without jQuery or other library:

<div id="x" style="background-color:rgb(255,255,105)">hello world</div>
<script type="text/javascript">
var gEvent=setInterval("toWhite();", 100);
function toWhite(){
    var obj=document.getElementById("x");
    var unBlue=10+parseInt(obj.style.backgroundColor.split(",")[2].replace(/\D/g,""));
    if(unBlue>245) unBlue=255;
    if(unBlue<256) obj.style.backgroundColor="rgb(255,255,"+unBlue+")";
    else clearInterval(gEvent)
}
</script>

In printing, yellow is minus blue, so starting with the 3rd rgb element (blue) at less than 255 starts out with a yellow highlight. Then the 10+ in setting the var unBlue value increments the minus blue until it reaches 255.

Generally what's meant by that is a fairly intimate familiarity with one (or probably more) of the .NET languages (C#, VB.NET, etc.) and one (or less probably more) of the .NET stacks (WinForms, ASP.NET, WPF, etc.).

As for a specific "formal definition", I don't think you'll find one beyond that. The job description should be specific about what they're looking for. I wouldn't consider a job listing that asks for a ".NET developer" and provides no more detail than that to be sufficiently descriptive.

#include <cmath>
#include <iostream>

using namespace std;

int main()

There must be a mismatch in the code you have posted and the one you're trying to compile.

Be sure there are no precompiled headers being pulled in before your #define.

At the moment I'm selecting like this:

$('a[data-attribute=true]')

Which seems to work just fine, but it would be nice if jQuery was able to select by that attribute without the 'data-' prefix.

I haven't tested this with data added to elements via jQuery dynamically, so that could be the downfall of this method.

Simply you can run

rake db:setup

It will drop database, create new database and populate db from seed if you created seed file with some data.

Assuming path is your String.

File file = new File(path);

boolean exists =      file.exists();      // Check if the file exists
boolean isDirectory = file.isDirectory(); // Check if it's a directory
boolean isFile =      file.isFile();      // Check if it's a regular file

See File Javadoc

Or you can use the NIO class Files and check things like this:

Path file = new File(path).toPath();

boolean exists =      Files.exists(file);        // Check if the file exists
boolean isDirectory = Files.isDirectory(file);   // Check if it's a directory
boolean isFile =      Files.isRegularFile(file); // Check if it's a regular file

I wrote a module that can do this, called BFJ. Specifically, the method bfj.match can be used to break up a large stream into discrete chunks of JSON:

const bfj = require('bfj');
const fs = require('fs');

const stream = fs.createReadStream(filePath);

bfj.match(stream, (key, value, depth) => depth === 0, { ndjson: true })
  .on('data', object => {
    // do whatever you need to do with object
  })
  .on('dataError', error => {
    // a syntax error was found in the JSON
  })
  .on('error', error => {
    // some kind of operational error occurred
  })
  .on('end', error => {
    // finished processing the stream
  });

Here, bfj.match returns a readable, object-mode stream that will receive the parsed data items, and is passed 3 arguments:

1. A readable stream containing the input JSON.

2. A predicate that indicates which items from the parsed JSON will be pushed to the result stream.

3. An options object indicating that the input is newline-delimited JSON (this is to process format B from the question, it's not required for format A).

Upon being called, bfj.match will parse JSON from the input stream depth-first, calling the predicate with each value to determine whether or not to push that item to the result stream. The predicate is passed three arguments:

1. The property key or array index (this will be undefined for top-level items).

2. The value itself.

3. The depth of the item in the JSON structure (zero for top-level items).

Of course a more complex predicate can also be used as necessary according to requirements. You can also pass a string or a regular expression instead of a predicate function, if you want to perform simple matches against property keys.

For example if I had an application source code structure that looked like this:

• C:\b2b\com\steve\util\
• C:\b2b\com\steve\app\
• C:\b2b\com\steve\gui\

Then I would do:

javadoc -d "C:\docs" -sourcepath "C:\b2b" -subpackages com

And that should create javadocs for source code of the com package, and all subpackages (recursively), found inside the "C:\b2b" directory.

You can do this locally as everyone mentioned using

git checkout -b <branch-name> <sha1-of-commit>

Alternatively, you can do this in github itself, follow the steps:

1- In the repository, click on the Commits.

2- on the commit you want to branch from, click on <> to browse the repository at this point in the history.

3- Click on the tree: xxxxxx in the upper left. Just type in a new branch name there click Create branch xxx as shown below.

Now you can fetch the changes from that branch locally and continue from there.

UPDATE Warning, this answer is extremely out of date now that OData V4 is available.

I wrote a post on the subject a while ago here.

As Franci said, OData is based on Atom Pub. However, they have layered some functionality on top and unfortunately have ignored some of the REST constraints in the process.

The querying capability of an OData service requires you to construct URIs based on information that is not available, or linked to in the response. It is what REST people call out-of-band information and introduces hidden coupling between the client and server.

The other coupling that is introduced is through the use of EDMX metadata to define the properties contained in the entry content. This metadata can be discovered at a fixed endpoint called $metadata. Again, the client needs to know this in advance, it cannot be discovered.

Unfortunately, Microsoft did not see fit to create media types to describe these key pieces of data, so any OData client has to make a bunch of assumptions about the service that it is talking to and the data it is receiving.

\ is used for escape sequences in programming languages.

\n prints a newline

Even i was facing the same problem ,but solved it by

conda install -c conda-forge pysoundfile

while importing it

import soundfile 

var str1 = 'abc';
var str2 = str1+' def'; // str2 is now 'abc def'

ObjectAnimator.ofFloat(view, View.ROTATION, 0f, 360f).setDuration(300).start();

Try this.

Display:flex apply flex layout to the flex items or children of the container only. So, the container itself stays a block level element and thus takes up the entire width of the screen.

This causes every flex container to move to a new line on the screen.

Display:inline-flex apply flex layout to the flex items or children as well as to the container itself. As a result the container behaves as an inline flex element just like the children do and thus takes up the width required by its items/children only and not the entire width of the screen.

This causes two or more flex containers one after another, displayed as inline-flex, align themselves side by side on the screen until the whole width of the screen is taken.

You have uniqid function for unique id

You can add prefix to make it more unique

Source : http://pk1.php.net/uniqid

You want either auto-fit or auto-fill inside the repeat() function:

grid-template-columns: repeat(auto-fit, 186px);

The difference between the two becomes apparent if you also use a minmax() to allow for flexible column sizes:

grid-template-columns: repeat(auto-fill, minmax(186px, 1fr));

This allows your columns to flex in size, ranging from 186 pixels to equal-width columns stretching across the full width of the container. auto-fill will create as many columns as will fit in the width. If, say, five columns fit, even though you have only four grid items, there will be a fifth empty column:

Using auto-fit instead will prevent empty columns, stretching yours further if necessary:

From the VIM Documentation

To clear the last used search pattern:

:let @/ = ""

This will not set the pattern to an empty string, because that would match everywhere. The pattern is really cleared, like when starting Vim.

You can use the limit(n) function:

l = [('Alice', 1),('Jim',2),('Sandra',3)]
df = sqlContext.createDataFrame(l, ['name', 'age'])
df.limit(2).withColumn('age2', df.age + 2).toPandas()

Or:

l = [('Alice', 1),('Jim',2),('Sandra',3)]
df = sqlContext.createDataFrame(l, ['name', 'age'])
df.withColumn('age2', df.age + 2).limit(2).toPandas()

If you are using other version control software, it may be in conflict. In my case, uninstalling Plastic SCM restored Tortoise SVN icons.

This is not exactly the answer to the question, but I end up here every time I want to find out how to get my batch file to exit with and error code when a process returns an nonzero code.

So here is the answer to that:

if %ERRORLEVEL% NEQ 0 exit %ERRORLEVEL%

I usually create a view and use the DESC command:

CREATE VIEW tmp_view AS 
SELECT 
      a.name
    , a.surname
    , b.ordernum 
FROM customer a
  JOIN orders b
    ON a.id = b.id

Then, the DESC command will show the type of each field.

DESC tmp_view

dataframe['column'].squeeze() should solve this. It basically changes the dataframe column to a list.

As of Spring 3.0, Spring offers support for JSR-330 dependency injection annotations (@Inject, @Named, @Singleton).

There is a separate section in the Spring documentation about them, including comparisons to their Spring equivalents.

In vue cli-3 You can define the variable in main.js like

window.basurl="http://localhost:8000/";

And you can also access this variable in any component by using the the window.basurl

Simply use fs module and something like this:

fs.appendFile('server.log', 'string to append', function (err) {
   if (err) return console.log(err);
   console.log('Appended!');
});

ALTER TABLE test1 ADD COLUMN id SERIAL PRIMARY KEY;

This is all you need to:

1. Add the id column
2. Populate it with a sequence from 1 to count(*).
3. Set it as primary key / not null.

[Minor changes to formatting made. Parenthetical annotations added in square brackets []].

The whole idea of using 'do/while' version is to make a macro which will expand into a regular statement, not into a compound statement. This is done in order to make the use of function-style macros uniform with the use of ordinary functions in all contexts.

Consider the following code sketch:

if (<condition>)
  foo(a);
else
  bar(a);

where foo and bar are ordinary functions. Now imagine that you'd like to replace function foo with a macro of the above nature [named CALL_FUNCS]:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

Now, if your macro is defined in accordance with the second approach (just { and }) the code will no longer compile, because the 'true' branch of if is now represented by a compound statement. And when you put a ; after this compound statement, you finished the whole if statement, thus orphaning the else branch (hence the compilation error).

One way to correct this problem is to remember not to put ; after macro "invocations":

if (<condition>)
  CALL_FUNCS(a)
else
  bar(a);

This will compile and work as expected, but this is not uniform. The more elegant solution is to make sure that macro expand into a regular statement, not into a compound one. One way to achieve that is to define the macro as follows:

#define CALL_FUNCS(x) \
do { \
  func1(x); \
  func2(x); \
  func3(x); \
} while (0)

Now this code:

if (<condition>)
  CALL_FUNCS(a);
else
  bar(a);

will compile without any problems.

However, note the small but important difference between my definition of CALL_FUNCS and the first version in your message. I didn't put a ; after } while (0). Putting a ; at the end of that definition would immediately defeat the entire point of using 'do/while' and make that macro pretty much equivalent to the compound-statement version.

I don't know why the author of the code you quoted in your original message put this ; after while (0). In this form both variants are equivalent. The whole idea behind using 'do/while' version is not to include this final ; into the macro (for the reasons that I explained above).

Create Learning Table:

CREATE TABLE "public"."learning" (
    "api_id" int4 DEFAULT nextval('share_api_api_id_seq'::regclass) NOT NULL,
    "title" varchar(255) COLLATE "default"
);

Insert Data Learning Table:

INSERT INTO "public"."learning" VALUES ('1', 'Google AI-01');
INSERT INTO "public"."learning" VALUES ('2', 'Google AI-02');
INSERT INTO "public"."learning" VALUES ('3', 'Google AI-01');

Step: 01

CREATE OR REPLACE FUNCTION get_all (pattern VARCHAR) RETURNS TABLE (
        learn_id INT,
        learn_title VARCHAR
) AS $$
BEGIN
    RETURN QUERY SELECT

In addition to:

myFilePath = replace(myFilePath, "/", "\")
myFilePath = replace(myFilePath, "http:", "")

also replace space:

The TryParse method allows you to test whether something is parseable. If you try Parse as in the first instance with an invalid int, you'll get an exception while in the TryParse, it returns a boolean letting you know whether the parse succeeded or not.

As a footnote, passing in null to most TryParse methods will throw an exception.

Here's yet another way (using a negative look-ahead):

^/(?!ignoreme|ignoreme2|ignoremeN)([a-z0-9]+)$ 

Note: There's only one capturing expression: ([a-z0-9]+).

With C++17 you can also return one ore more unmovable/uncopyable values (in certain cases). The possibility to return unmovable types come via the new guaranteed return value optimization, and it composes nicely with aggregates, and what can be called templated constructors.

template<typename T1,typename T2,typename T3>
struct many {
  T1 a;
  T2 b;
  T3 c;
};

// guide:
template<class T1, class T2, class T3>
many(T1, T2, T3) -> many<T1, T2, T3>;

auto f(){ return many{string(),5.7, unmovable()}; }; 

int main(){
   // in place construct x,y,z with a string, 5.7 and unmovable.
   auto [x,y,z] = f();
}

The pretty thing about this is that it is guaranteed to not cause any copying or moving. You can make the example many struct variadic too. More details:

Perhaps you were looking at the space complexity? That is O(n). The other complexities are as expected on the hash table entry. The search complexity approaches O(1) as the number of buckets increases. If at the worst case you have only one bucket in the hash table, then the search complexity is O(n).

Edit in response to comment I don't think it is correct to say O(1) is the average case. It really is (as the wikipedia page says) O(1+n/k) where K is the hash table size. If K is large enough, then the result is effectively O(1). But suppose K is 10 and N is 100. In that case each bucket will have on average 10 entries, so the search time is definitely not O(1); it is a linear search through up to 10 entries.

For those who wants to use Lodash can use: myArray = _.without(myArray, itemToRemove)

Or as I use in Angular2

import { without } from 'lodash';
...
myArray = without(myArray, itemToRemove);
...

You can't have a non-keyword argument after a keyword argument.

Make sure you re-arrange your function arguments like so:

def a(len1,til,hgt=len1,col=0):
    system('mode con cols='+len1,'lines='+hgt)
    system('title',til)
    system('color',col)

a(64,"hi",25,"0b")

I believe that the "problem" with all of the above is that it depends upon a certain implementation convention either of docker itself or its implementation and how that interacts with cgroups and /proc, and not via a committed, public, API, protocol or convention as part of the OCI specs.

Hence these solutions are "brittle" and likely to break when least expected when implementations change, or conventions are overridden by user configuration.

container and image ids should be injected into the r/t environment by the component that initiated the container instance, if for no other reason than to permit code running therein to use that information to uniquely identify themselves for logging/tracing etc...

just my $0.02, YMMV...

Add an additional div around all container divs you want the drop shadow to encapsulate. Add the classes drop-shadow and container to the additional div. The class .container will keep the fluidity. Use the class .drop-shadow (or whatever you like) to add the box-shadow property. Then target the .drop-shadow div and negate the unwanted styles .container adds--such as left & right padding.

Example: http://jsfiddle.net/SHLu4/2/

It'll be something like:

<div class="container drop-shadow">
    <div class="container">
        <div class="row">
            <div class="col-md-8">Main Area</div>
            <div class="col-md-4">Side Area</div>
        </div>
    </div>
</div>

And your CSS:

<style>
    .drop-shadow {
        -webkit-box-shadow: 0 0 5px 2px rgba(0, 0, 0, .5);
        box-shadow: 0 0 5px 2px rgba(0, 0, 0, .5);
    }
    .container.drop-shadow {
        padding-left:0;
        padding-right:0;
    }
</style>

For those that want it ISO 8601 compliant, since the other solutions do not have the T separator nor the time offset (except Meistro's answer):

from datetime import datetime, timezone
result = datetime.fromtimestamp(1463288494, timezone.utc).isoformat('T', 'microseconds')
print(result) # 2016-05-15T05:01:34.000000+00:00

Note, I use fromtimestamp because if I used utcfromtimestamp I would need to chain on .astimezone(...) anyway to get the offset.

If you don't want to go all the way to microseconds you can choose a different unit with the isoformat() method.

I prefer to install the PowerShell Community Extensions and just use the Get-FileVersionInfo function that it provides.

Like so:

Get-FileVersionInfo MyAssembly.dll

with output like:

ProductVersion   FileVersion      FileName
--------------   -----------      --------
1.0.2907.18095   1.0.2907.18095   C:\Path\To\MyAssembly.dll

I've used it against an entire directory of assemblies with great success.

This can happen when you mistakenly import an Android project into your Eclipse workspace as a Java project. The solution in this case: delete the project from the workspace in the Package Explorer, then go to File -> Import -> Android -> Existing Android code into workspace.

The real confusion here is not about parse vs stringify, it's about the data type of the data parameter of the success callback.

data can be either the raw response, i.e a string, or it can be an JavaScript object, as per the documentation:

success

Type: Function( Anything data, String textStatus, jqXHR jqXHR ) A function to be called if the request succeeds. The function gets passed three arguments: The data returned from the server, formatted according to the dataType parameter or the dataFilter callback function, if specified;<..>

And the dataType defaults to a setting of 'intelligent guess'

dataType (default: Intelligent Guess (xml, json, script, or html))

Type: String The type of data that you're expecting back from the server. If none is specified, jQuery will try to infer it based on the MIME type of the response (an XML MIME type will yield XML, in 1.4 JSON will yield a JavaScript object, in 1.4 script will execute the script, and anything else will be returned as a string).

Guys this is a generic method you can use for all your tables, Worked perfectly in my case.

public void deleteRowFromTable(String tableName, String columnName, String keyValue) {
    String whereClause = columnName + "=?";
    String[] whereArgs = new String[]{String.valueOf(keyValue)};
    yourDatabase.delete(tableName, whereClause, whereArgs);
}

-L returns true if the "file" exists and is a symbolic link (the linked file may or may not exist). You want -f (returns true if file exists and is a regular file) or maybe just -e (returns true if file exists regardless of type).

According to the GNU manpage, -h is identical to -L, but according to the BSD manpage, it should not be used:

-h file True if file exists and is a symbolic link. This operator is retained for compatibility with previous versions of this program. Do not rely on its existence; use -L instead.

This pulls back client info as well.

var get = function(u){
    var x = new XMLHttpRequest;
    x.open('GET', u, false);
    x.send();
    return x.responseText;
}

JSON.parse(get('http://ifconfig.me/all.json'))

    BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent(), "UTF-8"));
String sResponse;
StringBuilder s = new StringBuilder();

while ((sResponse = reader.readLine()) != null) {
    s = s.append(sResponse);
}
Gson gson = new Gson();

JSONObject jsonObject = new JSONObject(s.toString());
String link = jsonObject.getString("Result");

By the way, instead of generating the x and y coordinates yourself, you can also use the curve() function, which is intended to draw curves corresponding to a function (such as the density of a standard normal function).

see

help(curve)

and its examples.

And if you want to add som text to properly label the mean and standard deviations, you can use the text() function (see also plotmath, for annotations with mathematical symbols) .

see

help(text)

The experiment was: EXPERIMENT

Add a method to Card that creates a full deck of cards, with one card of each combination of rank and suit.

So without modifying or enhancing the given code other than adding the method (and without using stuff that hasn't been taught yet), I came up with this solution:

struct Card {
    var rank: Rank
    var suit: Suit

    func simpleDescription() -> String {
        return "The \(rank.simpleDescription()) of \(suit.simpleDescription())"
    }

    func createDeck() -> [Card] {
        var deck: [Card] = []
        for rank in Rank.Ace.rawValue...Rank.King.rawValue {
            for suit in Suit.Spades.rawValue...Suit.Clubs.rawValue {
                let card = Card(rank: Rank(rawValue: rank)!, suit: Suit(rawValue: suit)!)
                //println(card.simpleDescription())
                deck += [card]
            }
        }
        return deck
    }
}
let threeOfSpades = Card(rank: .Three, suit: .Spades)
let threeOfSpadesDescription = threeOfSpades.simpleDescription()
let deck = threeOfSpades.createDeck()

I got it to work by doing this, assuming you are using PDO.

//Place query here, let's say you want all the users that have blue as their favorite color
$sql = "SELECT name FROM user WHERE favorite_color = :color";

//set parameters 
//you may set as many parameters as you have on your query
$params['color'] = blue;


//create the prepared statement, by getting the doctrine connection
$stmt = $this->entityManager->getConnection()->prepare($sql);
$stmt->execute($params);
//I used FETCH_COLUMN because I only needed one Column.
return $stmt->fetchAll(PDO::FETCH_COLUMN);

You can change the FETCH_TYPE to suit your needs.

sometimes you have to take the whole external project as library and not only the jar:

my problem solved by adding the whole project (in my case google-play-services_lib) as library and not only the jar. the steps to to it (from @style answer):

1. File->New->Other
2. Select Android Project
3. Select "Create Project from existing source"
4. Click "Browse..." button and navigate to the wanted project
5. Finish (Now action bar project in your workspace)
6. Right-click on your project -> Properties
7. In Android->Library section click Add
8. select recently added project -> Ok

You had selected the time format wrong

<?php 
date_default_timezone_set('GMT');

echo date("Y-m-d,h:m:s");
?>

For Spring Boot, the accepted answer will overwrite duplicate properties with lower priority ones. This solution will collect the properties into a SortedMap and take only the highest priority duplicate properties.

final SortedMap<String, String> sortedMap = new TreeMap<>();
for (final PropertySource<?> propertySource : env.getPropertySources()) {
    if (!(propertySource instanceof EnumerablePropertySource))
        continue;
    for (final String name : ((EnumerablePropertySource<?>) propertySource).getPropertyNames())
        sortedMap.computeIfAbsent(name, propertySource::getProperty);
}

From lambda answer, I have made something closer to the requirements.

boolean imageCreated = false;

Bitmap bmp = null;
Marker currentLocationMarker;
private void doSomeCustomizationForMarker(LatLng currentLocation) {
    if (!imageCreated) {
        imageCreated = true;
        Bitmap.Config conf = Bitmap.Config.ARGB_8888;
        bmp = Bitmap.createBitmap(400, 400, conf);
        Canvas canvas1 = new Canvas(bmp);

        Paint color = new Paint();
        color.setTextSize(30);
        color.setColor(Color.WHITE);

        BitmapFactory.Options opt = new BitmapFactory.Options();
        opt.inMutable = true;

        Bitmap imageBitmap=BitmapFactory.decodeResource(getResources(),
                R.drawable.messi,opt);
        Bitmap resized = Bitmap.createScaledBitmap(imageBitmap, 320, 320, true);
        canvas1.drawBitmap(resized, 40, 40, color);

        canvas1.drawText("Le Messi", 30, 40, color);

        currentLocationMarker = mMap.addMarker(new MarkerOptions().position(currentLocation)
                .icon(BitmapDescriptorFactory.fromBitmap(bmp))
                // Specifies the anchor to be at a particular point in the marker image.
                .anchor(0.5f, 1));
    } else {
        currentLocationMarker.setPosition(currentLocation);
    }

}

Set force Portrait or Landscape mode, Add lines respectively.

Import below line:

import android.content.pm.ActivityInfo;

Add Below line just above setContentView(R.layout.activity_main);

For Portrait:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);//Set Portrait

For Landscap:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);//Set Landscape

This will definitely work.

git branch -f <branchname> <commit>

I go with Mark Longair's solution and comments and recommend anyone reads those before acting, but I'd suggest the emphasis should be on

git branch -f <branchname> <commit>

Here is a scenario where I have needed to do this.

Scenario

Develop on the wrong branch and hence need to reset it.

Start Okay

Cleanly develop and release some software.

Develop on wrong branch

Mistake: Accidentally stay on the release branch while developing further.

Realize the mistake

"OH NO! I accidentally developed on the release branch." The workspace is maybe cluttered with half changed files that represent work-in-progress and we really don't want to touch and mess with. We'd just like git to flip a few pointers to keep track of the current state and put that release branch back how it should be.

Create a branch for the development that is up to date holding the work committed so far and switch to it.

git branch development
git checkout development 

Correct the branch

Now we are in the problem situation and need its solution! Rectify the mistake (of taking the release branch forward with the development) and put the release branch back how it should be.

Correct the release branch to point back to the last real release.

git branch -f release release2

The release branch is now correct again, like this ...

What if I pushed the mistake to a remote?

git push -f <remote> <branch> is well described in another thread, though the word "overwrite" in the title is misleading. Force "git push" to overwrite remote files

Make sure drush is installed (you may also need to make sure the dblog module is enabled) and use:

drush watchdog-show --tail

Available in drush v8 and below.

This will give you a live look at the logs from your console.

I think you have basically five different options to do so. Choosing among them could be easy depending on the goal you would like to achieve.

The best way in most of the cases to use a class and instantiate it, because you are using TypeScript to apply type checking.

interface IModal {
    content: string;
    form: string;
    //...

    //Extra
    foo: (bar: string): void;
}

class Modal implements IModal {
    content: string;
    form: string;

    foo(param: string): void {
    }
}

Even if other methods are offering easier ways to create an object from an interface you should consider splitting your interface apart, if you are using your object for different matters, and it does not cause interface over-segregation:

interface IBehaviour {
    //Extra
    foo(param: string): void;
}

interface IModal extends IBehaviour{
    content: string;
    form: string;
    //...
}

On the other hand, for example during unit testing your code (if you may not applying separation of concerns frequently), you may be able to accept the drawbacks for the sake of productivity. You may apply other methods to create mocks mostly for big third party *.d.ts interfaces. And it could be a pain to always implement full anonymous objects for every huge interface.

On this path your first option is to create an empty object:

 var modal = <IModal>{};

Secondly to fully realise the compulsory part of your interface. It can be useful whether you are calling 3rd party JavaScript libraries, but I think you should create a class instead, like before:

var modal: IModal = {
    content: '',
    form: '',
    //...

    foo: (param: string): void => {
    }
};

Thirdly you can create just a part of your interface and create an anonymous object, but this way you are responsible to fulfil the contract

var modal: IModal = <any>{
    foo: (param: string): void => {

    }
};

Summarising my answer even if interfaces are optional, because they are not transpiled into JavaScript code, TypeScript is there to provide a new level of abstraction, if used wisely and consistently. I think, just because you can dismiss them in most of the cases from your own code you shouldn't.

The ScriptIgnoreAttribute class is in the System.Web.Extensions.dll assembly (Located under Assemblies > Framework in the VS Reference Manager). You have to add a reference to that assembly in your class library project.

You can find this information at top of the MSDN page for the ScriptIgnoreAttribute class.

A few years late but hopefully this will help someone else...

1) First make sure the EC2 instance has a public IP. If has a Public DNS or Public IP address (circled below) then you should be good. This will be the address you ping.

2) Next make sure the Amazon network rules allow Echo Requests. Go to the Security Group for the EC2.

• right click, select inbound rules
• A: select Add Rule
• B: Select Custom ICMP Rule - IPv4
• C: Select Echo Request
• D: Select either Anywhere or My IP
• E: Select Save

3) Next, Windows firewall blocks inbound Echo requests by default. Allow Echo requests by creating a windows firewall exception...

• Go to Start and type Windows Firewall with Advanced Security
• Select inbound rules

4) Done! Hopefully you should now be able to ping your server.

I followed the instructions http://springflex.blogspot.ru/2014/02/how-to-fix-valueerror-when-trying-to.html. but nothing happened. Then I installed 2010 Visual Studio Express (http://www.microsoft.com/visualstudio/en-us/products/2010-editions/visual-cpp-express) following the advice http://blog.python.org/2012/05/recent-windows-changes-in-python-33.html it helped me

If you want to just run a quick code snippet you can use the -r option:

php -r "echo 'hi';"

-r allows to run code without using script tags <?..?>

To handle many newline delimiters, including character combinations like \r\n, use splitlines (see this related post) use the following:

'<br />'.join(thatLine.splitlines())

I uploaded my codeigniter project on Directadmin panel. I was getting same error.

Then I change in php settings.

open_basedir = session.save_path = ./temp/

Then it worked for me.

It's very simple really. Use percentage for width and left properties. For example:

logo : {
  position: 'absolute',
  top : 50,
  left: '30%',
  zIndex: 1,
  width: '40%',
  height: 150,
}

Whatever width is, left equals (100% - width)/2

:goto 21490 will take you to the 21490th byte in the buffer.

$('#' + theMysteryId + '.someClass').each(function() { /* do stuff */ });

When you want to treat lambda expressions as expression trees and look inside them instead of executing them. For example, LINQ to SQL gets the expression and converts it to the equivalent SQL statement and submits it to server (rather than executing the lambda).

Conceptually, Expression<Func<T>> is completely different from Func<T>. Func<T> denotes a delegate which is pretty much a pointer to a method and Expression<Func<T>> denotes a tree data structure for a lambda expression. This tree structure describes what a lambda expression does rather than doing the actual thing. It basically holds data about the composition of expressions, variables, method calls, ... (for example it holds information such as this lambda is some constant + some parameter). You can use this description to convert it to an actual method (with Expression.Compile) or do other stuff (like the LINQ to SQL example) with it. The act of treating lambdas as anonymous methods and expression trees is purely a compile time thing.

Func<int> myFunc = () => 10; // similar to: int myAnonMethod() { return 10; }

will effectively compile to an IL method that gets nothing and returns 10.

Expression<Func<int>> myExpression = () => 10;

will be converted to a data structure that describes an expression that gets no parameters and returns the value 10:

While they both look the same at compile time, what the compiler generates is totally different.

0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.

There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.

I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException and Application.ThreadException, as appropriate.

From the MySQL manual

INSERT statements that use VALUES syntax can insert multiple rows. To do this, include multiple lists of column values, each enclosed within parentheses and separated by commas. Example:

INSERT INTO tbl_name (a,b,c) VALUES(1,2,3),(4,5,6),(7,8,9);

I searched for a the same solution with a variable instead of the String.
I hope i can help someone with my solution :)

Quick guide to setup a cron job

Create a new text file, example: mycronjobs.txt

For each daily job (00:00, 03:45), save the schedule lines in mycronjobs.txt

00 00 * * * ruby path/to/your/script.rb
45 03 * * * path/to/your/script2.sh

Send the jobs to cron (everytime you run this, cron deletes what has been stored and updates with the new information in mycronjobs.txt)

crontab mycronjobs.txt

Extra Useful Information

See current cron jobs

crontab -l

Remove all cron jobs

crontab -r

In addition to Eric Leschinski's answer, and because this is stackoverflow, a programmatical solution:

Windows uses hidden file forks to mark content as "downloaded". Truncating these unblocks the file. The name of the stream used for CHM's is "Zone.Identifier". One can access streams by appending :streamname when opening the file. (keep backups the first time, in case your RTL messes that up!)

In Delphi it would look like this:

var f : file;
begin
 writeln('unblocking ',s);
 assignfile(f,'some.chm:Zone.Identifier');
 rewrite(f,1);
 truncate(f);
 closefile(f);
end;

I'm told that on non forked filesystems (like FAT32) there are hidden files, but I haven't gotten to the bottom of that yet.

P.s. Delphi's DeleteFile() should also recognize forks.

guys, I have also encountered this problem after having so much research on this issue I found 3 solutions to resolve this issue

1. Add these properties in your pom.xml; //Sorry for the formatting

<properties><java.version>1.8</java.version<maven.compiler.version>3.8.1</maven.compiler.version<maven.compiler.source>1.8</maven.compiler.source<maven.compiler.target>1.8</maven.compiler.target><java.version>11</java.version></properties>

2. Delete everything in the target byte version, you can find this in the java compiler setting of the IntelliJ

Remove everything below target byte version make it empty

3. Find the appium version you are using in the dependency. here I am using 7.3.0 find the version of the appium you are using in the dependency in pom.xml

Then write your version in the target byte version in java compiler enter image description here

ENJOY THE CODE>>>HOPE IT WORKED FOR YOU

I just noticed that with C++20, we will have

bool std::map::contains( const Key& key ) const;

That will return true if map holds an element with key key.

For the first ten multiples of 5, say

>>> [5*n for n in range(1,10+1)]
[5, 10, 15, 20, 25, 30, 35, 40, 45, 50]

Usually for defining constants, that you reuse at many places making it single point for change, used within single class or shared across packages. Making a variable final avoid accidental changes.

Support for the extended ternary operator was added in Twig 1.12.0.

1. If foo echo yes else echo no:

   {{ foo ? 'yes' : 'no' }}
   

2. If foo echo it, else echo no:

   {{ foo ?: 'no' }}
   

   or

   {{ foo ? foo : 'no' }}
   

3. If foo echo yes else echo nothing:

   {{ foo ? 'yes' }}
   

   or

   {{ foo ? 'yes' : '' }}
   

4. Returns the value of foo if it is defined and not null, no otherwise:

   {{ foo ?? 'no' }}
   

5. Returns the value of foo if it is defined (empty values also count), no otherwise:

   {{ foo|default('no') }}
   

Actually, x is post-decrementing and with that condition is being checked. It's not -->, it's (x--) > 0

Note: value of x is changed after the condition is checked, because it post-decrementing. Some similar cases can also occur, for example:

-->    x-->0
++>    x++>0
-->=   x-->=0
++>=   x++>=0

#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>
#include <stdlib.h>
#include <sys/wait.h>

int main (){
    int pid;
    int status;

    printf("Parent: %d\n", getpid());

    pid = fork();
    if (pid == 0){
        printf("Child %d\n", getpid());
        sleep(2);
        exit(EXIT_SUCCESS);
    }

//Comment from here to...
    //Parent waits process pid (child)
    waitpid(pid, &status, 0);
    //Option is 0 since I check it later

    if (WIFSIGNALED(status)){
        printf("Error\n");
    }
    else if (WEXITSTATUS(status)){
        printf("Exited Normally\n");
    }
//To Here and see the difference
    printf("Parent: %d\n", getpid());

    return 0;
}

Yes, it is possible. Though I wouldn't recommend it because input range is not really supported properly by all browsers because is an new element added in HTML5 and HTML5 is only a draft (and will be for long) so going as far as to styling it is perhaps not the best choice.

Also, you'll need a bit of JavaScript too. I took the liberty of using jQuery library for this, for simplicity purposes.

Here you go: http://jsfiddle.net/JnrvG/1/.

I also encountered the same problem, my problem has been resolved. The solution is:

According to error information being given, to find the corresponding jar in maven repository and deleted. Then executed mvn install command after deleting.

I have same issue when I was trying out Laravel 5.2 at first, then I learnt about {{!! csrf_field() !!}} to be added in the form and that solved it. But later I learnt about Form Helpers, this takes care of CSRF protection and does not give any errors. Though Form Helpers are not legitimately available after Laravel 5.2, you can still use them from LaravelCollective.

Using an element-wise logical or and setting the take_last argument of the pandas duplicated method to both True and False you can obtain a set from your dataframe that includes all of the duplicates.

df_bigdata_duplicates = 
    df_bigdata[df_bigdata.duplicated(cols='ID', take_last=False) |
               df_bigdata.duplicated(cols='ID', take_last=True)
              ]

This question is specific to ASP .NET however I am sure some of you will benefit of system agnostic javascript which is beneficial in many situations.

UPDATE: The way to get url formed outside of the page itself is well described in answers above.

Or you could do a oneliner like following:

new UrlHelper(actionExecutingContext.RequestContext).Action(
    "SessionTimeout", "Home", 
    new {area = string.Empty}, 
    actionExecutingContext.Request.Url!= null? 
    actionExecutingContext.Request.Url.Scheme : "http"
);

from filter or:

new UrlHelper(this.Request.RequestContext).Action(
    "Details", 
    "Journey", 
    new { area = productType }, 
    this.Request.Url!= null? this.Request.Url.Scheme : "http"
);

However quite often one needs to get the url of current page, for those cases using Html.Action and putting he name and controller of page you are in to me feels awkward. My preference in such cases is to use JavaScript instead. This is especially good in systems that are half re-written MVT half web-forms half vb-script half God knows what - and to get URL of current page one needs to use different method every time.

One way is to use JavaScript to get URL is window.location.href another - document.URL

When I'm working with csv files, I often use the pandas library. It makes things like this very easy. For example:

import pandas as pd

a = pd.read_csv("filea.csv")
b = pd.read_csv("fileb.csv")
b = b.dropna(axis=1)
merged = a.merge(b, on='title')
merged.to_csv("output.csv", index=False)

Some explanation follows. First, we read in the csv files:

>>> a = pd.read_csv("filea.csv")
>>> b = pd.read_csv("fileb.csv")
>>> a
   title  stage    jan    feb
0   darn  3.001  0.421  0.532
1     ok  2.829  1.036  0.751
2  three  1.115  1.146  2.921
>>> b
   title    mar    apr    may       jun  Unnamed: 5
0   darn  0.631  1.321  0.951    1.7510         NaN
1     ok  1.001  0.247  2.456    0.3216         NaN
2  three  0.285  1.283  0.924  956.0000         NaN

and we see there's an extra column of data (note that the first line of fileb.csv -- title,mar,apr,may,jun, -- has an extra comma at the end). We can get rid of that easily enough:

>>> b = b.dropna(axis=1)
>>> b
   title    mar    apr    may       jun
0   darn  0.631  1.321  0.951    1.7510
1     ok  1.001  0.247  2.456    0.3216
2  three  0.285  1.283  0.924  956.0000

Now we can merge a and b on the title column:

>>> merged = a.merge(b, on='title')
>>> merged
   title  stage    jan    feb    mar    apr    may       jun
0   darn  3.001  0.421  0.532  0.631  1.321  0.951    1.7510
1     ok  2.829  1.036  0.751  1.001  0.247  2.456    0.3216
2  three  1.115  1.146  2.921  0.285  1.283  0.924  956.0000

and finally write this out:

>>> merged.to_csv("output.csv", index=False)

producing:

title,stage,jan,feb,mar,apr,may,jun
darn,3.001,0.421,0.532,0.631,1.321,0.951,1.751
ok,2.829,1.036,0.751,1.001,0.247,2.456,0.3216
three,1.115,1.146,2.921,0.285,1.283,0.924,956.0

I found this solution useful in a NodeJS app. I use it just in desperate cases because it launches a timeout in order to wait for the full page load.

The second argument is the callback function which is going to be called once the response is ready.

phantom = require('phantom');

var fullLoad = function(anUrl, callbackDone) {
    phantom.create(function (ph) {
        ph.createPage(function (page) {
            page.open(anUrl, function (status) {
                if (status !== 'success') {
                    console.error("pahtom: error opening " + anUrl, status);
                    ph.exit();
                } else {
                    // timeOut
                    global.setTimeout(function () {
                        page.evaluate(function () {
                            return document.documentElement.innerHTML;
                        }, function (result) {
                            ph.exit(); // EXTREMLY IMPORTANT
                            callbackDone(result); // callback
                        });
                    }, 5000);
                }
            });
        });
    });
}

var callback = function(htmlBody) {
    // do smth with the htmlBody
}

fullLoad('your/url/', callback);

It is possible to handle these exceptions with Thread.setDefaultUncaughtExceptionHandler(), however this appears to mess with Android's method of handling exceptions. I attempted to use a handler of this nature:

private class ExceptionHandler implements Thread.UncaughtExceptionHandler {
    @Override
    public void uncaughtException(Thread thread, Throwable ex){
        Log.e(Constants.TAG, "uncaught_exception_handler: uncaught exception in thread " + thread.getName(), ex);

        //hack to rethrow unchecked exceptions
        if(ex instanceof RuntimeException)
            throw (RuntimeException)ex;
        if(ex instanceof Error)
            throw (Error)ex;

        //this should really never happen
        Log.e(Constants.TAG, "uncaught_exception handler: unable to rethrow checked exception");
    }
}

However, even with rethrowing the exceptions, I was unable to get the desired behavior, ie logging the exception while still allowing Android to shutdown the component it had happened it, so I gave up on it after a while.

for xampp vm on MacOS capitan, high sierra, MacOS Mojave (10.12+), you can follow these

1. mount /opt/lampp
2. explore the folder
3. open terminal from the folder
4. cd to `htdocs`>yourapp (ex: techaz.co)
5. vim .htaccess
6. paste your .htaccess content (that is suggested on options-permalink.php)

I've recently found how to trigger mouse click event via jQuery.

    <script type="text/javascript">
    var a = $('.path > .to > .element > a')[0];
    var e = document.createEvent('MouseEvents');
    e.initEvent( 'click', true, true );
    a.dispatchEvent(e);
    </script>

What? The person asked for Linux specific, and the equivalent of getpid(). Not BSD or Apple. The answer is gettid() and returns an integral type. You will have to call it using syscall(), like this:

#include <sys/types.h>
#include <unistd.h>
#include <sys/syscall.h>

 ....

 pid_t x = syscall(__NR_gettid);

While this may not be portable to non-linux systems, the threadid is directly comparable and very fast to acquire. It can be printed (such as for LOGs) like a normal integer.

On Ubuntu (direct edit) :

$ sudo nano /etc/mysql.conf.d/mysqld.cnf

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=yourpassword
MAIL_ENCRYPTION=tls
MAIL_FROM_NAME='Name'

allow less secure apps to access your account in the Gmail security setting.

I searched and searched and finally found that ie needs to know the map size. Set the map size to match the div size.

map = new GMap2(document.getElementById("map_canvas2"), { size: new GSize(850, 600) });

<div id="map_canvas2" style="width: 850px; height: 600px">
</div>

In Flask 1.1, if you return a dictionary and it will automatically be converted into JSON. So if make_summary() returns a dictionary, you can

from flask import Flask

app = Flask(__name__)

@app.route('/summary')
def summary():
    d = make_summary()
    return d

The SO that asks about including the status code was closed as a duplicate to this one. So to also answer that question, you can include the status code by returning a tuple of the form (dict, int). The dict is converted to JSON and the int will be the HTTP Status Code. Without any input, the Status is the default 200. So in the above example the code would be 200. In the example below it is changed to 201.

from flask import Flask

app = Flask(__name__)

@app.route('/summary')
def summary():
    d = make_summary()
    return d, 201  # 200 is the default

You can check the status code using

curl --request GET "http://127.0.0.1:5000/summary" -w "\ncode: %{http_code}\n\n"

Just dump the data in delimited-text format.

The problem I have with solution

import sys

for line in sys.stdin:
    print(line)

is that if you don't pass any data to stdin, it will block forever. That's why I love this answer: check if there is some data on stdin first, and then read it. This is what I ended up doing:

import sys
import select

# select(files to read from, files to write to, magic, timeout)
# timeout=0.0 is essential b/c we want to know the asnwer right away
if select.select([sys.stdin], [], [], 0.0)[0]:
    help_file_fragment = sys.stdin.read()
else:
    print("No data passed to stdin", file=sys.stderr)
    sys.exit(2)

In Typescript and ES6 you can also use for..of:

for (var product of products) {
     console.log(product.product_desc)
}

which will be transcoded to javascript:

for (var _i = 0, products_1 = products; _i < products_1.length; _i++) {
    var product = products_1[_i];
    console.log(product.product_desc);
}

You misunderstand what "undefined behavior" means. Undefined behavior does not mean "if you do this, your program will crash or produce unexpected results." It means "if you do this, your program could crash or produce unexpected results", or do anything else, depending on your compiler, your operating system, the phase of the moon, etc.

If something executes without crashing and behaves as you expect it to, that is not proof that it is not undefined behavior. All it proves is that its behavior happened to be as observed for that particular run after compiling with that particular compiler on that particular operating system.

Erasing an element from a set invalidates the iterator to the erased element. Using an invalidated iterator is undefined behavior. It just so happened that the observed behavior was what you intended in this particular instance; it does not mean that the code is correct.

Usually you don't have to worry about calculating them as your assembler (or linker) will take of getting the calculations right. Let's say you have a small function:

func:
  slti $t0, $a0, 2
  beq $t0, $zero, cont
  ori $v0, $zero, 1
  jr $ra
cont:
  ...
  jal func
  ... 

When translating the above code into a binary stream of instructions the assembler (or linker if you first assembled into an object file) it will be determined where in memory the function will reside (let's ignore position independent code for now). Where in memory it will reside is usually specified in the ABI or given to you if you're using a simulator (like SPIM which loads the code at 0x400000 - note the link also contains a good explanation of the process).

Assuming we're talking about the SPIM case and our function is first in memory, the slti instruction will reside at 0x400000, the beq at 0x400004 and so on. Now we're almost there! For the beq instruction the branch target address is that of cont (0x400010) looking at a MIPS instruction reference we see that it is encoded as a 16-bit signed immediate relative to the next instruction (divided by 4 as all instructions must reside on a 4-byte aligned address anyway).

That is:

Current address of instruction + 4 = 0x400004 + 4 = 0x400008
Branch target = 0x400010
Difference = 0x400010 - 0x400008 = 0x8
To encode = Difference / 4 = 0x8 / 4 = 0x2 = 0b10

Encoding of beq $t0, $zero, cont

0001 00ss ssst tttt iiii iiii iiii iiii
---------------------------------------
0001 0001 0000 0000 0000 0000 0000 0010

As you can see you can branch to within -0x1fffc .. 0x20000 bytes. If for some reason, you need to jump further you can use a trampoline (an unconditional jump to the real target placed placed within the given limit).

Jump target addresses are, unlike branch target addresses, encoded using the absolute address (again divided by 4). Since the instruction encoding uses 6 bits for the opcode, this only leaves 26 bits for the address (effectively 28 given that the 2 last bits will be 0) therefore the 4 bits most significant bits of the PC register are used when forming the address (won't matter unless you intend to jump across 256 MB boundaries).

Returning to the above example the encoding for jal func is:

Destination address = absolute address of func = 0x400000
Divided by 4 = 0x400000 / 4 = 0x100000
Lower 26 bits = 0x100000 & 0x03ffffff = 0x100000 = 0b100000000000000000000

0000 11ii iiii iiii iiii iiii iiii iiii
---------------------------------------
0000 1100 0001 0000 0000 0000 0000 0000

You can quickly verify this, and play around with different instructions, using this online MIPS assembler i ran across (note it doesn't support all opcodes, for example slti, so I just changed that to slt here):

00400000: <func>    ; <input:0> func:
00400000: 0000002a  ; <input:1> slt $t0, $a0, 2
00400004: 11000002  ; <input:2> beq $t0, $zero, cont
00400008: 34020001  ; <input:3> ori $v0, $zero, 1
0040000c: 03e00008  ; <input:4> jr $ra
00400010: <cont>    ; <input:5> cont:
00400010: 0c100000  ; <input:7> jal func

It should normally be done with Request.Form["elementName"].

For example, if you have <input type="text" name="email" /> then you can use Request.Form["email"] to access its value.

The best way to handle styling is by using classes with set of css properties.

example:

<Component className={this.getColor()} />

getColor() {
    let class = "badge m2";
    class += this.state.count===0 ? "warning" : danger;
    return class;
}

Use a container with Boxdercoration.

 BoxDecoration(
    border: Border.all(
      width: 3.0
    ),
    borderRadius: BorderRadius.circular(10.0)
  );

According to the Bill Higgins' Blog post; the Javascript logical OR assignment idiom (Feb. 2007), this behavior is true as of v1.2 (at least)

He also suggests another use for it (quoted): "lightweight normalization of cross-browser differences"

// determine upon which element a Javascript event (e) occurred
var target = /*w3c*/ e.target || /*IE*/ e.srcElement;

Learning C forces you to think harder about some issues such as explicit and implicit memory management or storage sizes of basic data types at the time you write your code.

Once you have reached a point where you feel comfortable around C's features and misfeatures, you will probably have less trouble learning and writing in C++.

It is entirely possible that the C++ code you have seen did not look much different from standard C, but that may well be because it was not object oriented and did not use exceptions, object-orientation, templates or other advanced features.

I've also had this problem recently.

The solution that worked for me was to uninstall vmware, restart windows, and the reinstall vmware.

It would return NULL but if taken as BIGINT would show the number

In Eclipse:

• goto run menu -> run configuration.
• right click on android application on the right side and click new.
• fill the corresponding details like project name under the android tab.
• then under the target tab.
• select 'launch on all compatible devices and then select active devices from the drop down list'.
• save the configuration and run it by either clicking run on the 'run' button on the bottom right side of the window or close the window and run again

You can use LABJS or RequreJS

Script loaders like LABJS, RequireJS will improve the speed and quality of your code.

router.js

routes: [
{
  path: '/',
  component: test,
  meta: {
    reload: true,
  },
}]

main.js

import router from './router';

new Vue({
  render: h => h(App),
  router,
  watch:{
    '$route' (to) {
       if(to.currentRoute.meta.reload==true){window.location.reload()}
   }
 }).$mount('#app')

Now (2020) NetBeans 11 does it automatically with the "Build" command (right click on the project's name and choose "Build")

Using a date picker to get date and a time picker I get two variables, this is how I put them together in unixtime format and then pull them out...

let datetime = oDdate+' '+oDtime;
let unixtime = Date.parse(datetime)/1000;
console.log('unixtime:',unixtime);

to prove it:

let milliseconds = unixtime * 1000;
dateObject = new Date(milliseconds);
console.log('dateObject:',dateObject);

enjoy!

$scope.$watch('myVar', function (newValue, oldValue) {
        if (typeof (newValue) !== 'undefined') {
            $scope.someothervar= newValue;
//or get some data
            getData();
        }


    }, true);

Variable initializes after controller so you need to watch over it and when it't initialized the use it.

You need to iterate both the groups and the items. $.each() takes a collection as first parameter and data.response.venue.tips.groups.items.text tries to point to a string. Both groups and items are arrays.

Verbose version:

$.getJSON(url, function (data) {

    // Iterate the groups first.
    $.each(data.response.venue.tips.groups, function (index, value) {

        // Get the items
        var items = this.items; // Here 'this' points to a 'group' in 'groups'

        // Iterate through items.
        $.each(items, function () {
            console.log(this.text); // Here 'this' points to an 'item' in 'items'
        });
    });
});

Or more simply:

$.getJSON(url, function (data) {
    $.each(data.response.venue.tips.groups, function (index, value) {
        $.each(this.items, function () {
            console.log(this.text);
        });
    });
});

In the JSON you specified, the last one would be:

$.getJSON(url, function (data) {
    // Get the 'items' from the first group.
    var items = data.response.venue.tips.groups[0].items;

    // Find the last index and the last item.
    var lastIndex = items.length - 1;
    var lastItem = items[lastIndex];

    console.log("User: " + lastItem.user.firstName + " " + lastItem.user.lastName);
    console.log("Date: " + lastItem.createdAt);
    console.log("Text: " + lastItem.text);
});

This would give you:

getopt is your friend.. a simple example:

function f () {
TEMP=`getopt --long -o "u:h:" "$@"`
eval set -- "$TEMP"
while true ; do
    case "$1" in
        -u )
            user=$2
            shift 2
        ;;
        -h )
            host=$2
            shift 2
        ;;
        *)
            break
        ;;
    esac 
done;

echo "user = $user, host = $host"
}

f -u myself -h some_host

There should be various examples in your /usr/bin directory.

Haskell uses init to refer to all but the last element of a list (the inverse of tail, basically); would isInInit work, or is that too opaque?

This may be the good solution for you: change the code like this very little change

.box{
    position: relative; 
}
.box:hover .hidden{
    opacity: 1;
    width:500px;
}
.box .hidden{
    background: yellow;
    height: 334px; 
    position: absolute;
    top: 0;
    left: 0;
    width: 0;
    opacity: 0;
    transition: all 1s ease;
}

you have to tell git where to pull from, in this case from the current directory/repository:

git pull . master

but when working locally, you usually just call merge (pull internally calls merge):

git merge master

To change the Android-x86 screen resolution on VirtualBox you need to:

1. Add custom screen resolution:
   Android <6.0:

   VBoxManage setextradata "VM_NAME_HERE" "CustomVideoMode1" "320x480x16"
   

   Android >=6.0:

   VBoxManage setextradata "VM_NAME_HERE" "CustomVideoMode1" "320x480x32"
   

2. Figure out what is the ‘hex’-value for your VideoMode:
   2.1. Start the VM
   2.2. In GRUB menu enter a (Android >=6.0: e)
   2.3. In the next screen append vga=ask and press Enter
   2.4. Find your resolution and write down/remember the 'hex'-value for Mode column

3. Translate the value to decimal notation (for example 360 hex is 864 in decimal).

4. Go to menu.lst and modify it:
   4.1. From the GRUB menu select Debug Mode
   4.2. Input the following:

   mount -o remount,rw /mnt  
   cd /mnt/grub  
   vi menu.lst
   

   4.3. Add vga=864 (if your ‘hex’-value is 360). Now it should look like this:

   kernel /android-2.3-RC1/kernel quiet root=/dev/ram0 androidboot_hardware=eeepc acpi_sleep=s3_bios,s3_mode DPI=160 UVESA_MODE=320x480 SRC=/android-2.3-RC1 SDCARD=/data/sdcard.img vga=864

   4.4. Save it:

   :wq
   

5. Unmount and reboot:

   cd /
   umount /mnt
   reboot -f
   

Hope this helps.

Instead of using http GET, use http POST. And JSON. Or XML

This is how your request stream to the server would look like.

POST /appointments HTTP/1.0
Content-Type: application/json
Content-Length: (calculated by your utility)

{users: [user:{id:id1}, user:{id:id2}]}

Or in XML,

POST /appointments HTTP/1.0
Content-Type: application/json
Content-Length: (calculated by your utility)

<users><user id='id1'/><user id='id2'/></users>

You could certainly continue using GET as you have proposed, as it is certainly simpler.

/appointments?users=1d1,1d2

Which means you would have to keep your data structures very simple.

However, if/when your data structure gets more complex, http GET and without JSON, your programming and ability to recognise the data gets very difficult.

Therefore,unless you could keep your data structure simple, I urge you adopt a data transfer framework. If your requests are browser based, the industry usual practice is JSON. If your requests are server-server, than XML is the most convenient framework.

JQuery

If your client is a browser and you are not using GWT, you should consider using jquery REST. Google on RESTful services with jQuery.

EDIT: Even though this answer is marked as the correct answer (in 2013), currently, as answered by @user2511630 below, you can drag-n-drop apk files directly into the emulator to install them.

Original Answer:

You can install .apk files to emulator regardless of what you are using (Eclipse or Android Studio)

here's what I always do: (For full beginners)

1- Run the emulator, and wait until it's completely started.

2- Go to your sdk installation folder then go to platform-tools (you should see an executable called adb.exe)

3- create a new file and call it run.bat, edit the file with notepad and write CMD in it and save it.

4- copy your desired apk to the same folder

5- now open run.bat and write adb install "your_apk_file.apk"

6- wait until the installation is complete

7- voila your apk is installed to your emulator.

Note: to re-install the application if it already existe use adb install -r "your_apk_file.apk"

sorry for the detailed instruction as I said for full beginners

Hope this help.

Tarek

That should work:

>>> df = pd.DataFrame()
>>> data = pd.DataFrame({"A": range(3)})
>>> df.append(data)
   A
0  0

But the append doesn't happen in-place, so you'll have to store the output if you want it:

>>> df
Empty DataFrame
Columns: []
Index: []
>>> df = df.append(data)
>>> df
   A
0  0
1  1

For people like me who like one line solutions:

public int getHeight(Node root) {
    return Math.max(root.left != null ? getHeight(root.left) : -1, 
                    root.right != null ? getHeight(root.right) : -1) 
                    + 1;
}

You may find QString::fromUtf8() also useful.

For QByteArray input of "\010" and "\000",

QString::fromLocal8Bit(input, 1) returns "\010" and ""

QString::fromUtf8(input, 1) correctly returns "\010" and "\000".
