window.location.href is not a method, it's a property that will tell you the current URL location of the browser. Changing the value of the property will redirect the page.

window.open() is a method that you can pass a URL to that you want to open in a new window. For example:

window.location.href example:

window.location.href = 'http://www.google.com'; //Will take you to Google.

window.open() example:

window.open('http://www.google.com'); //This will open Google in a new window.

window.open() can be passed additional parameters. See: window.open tutorial

return el instanceof jQuery ? el.size() > 0 : (el && el.tagName);

Diagnose

If you have pip installed (you should have it until you use Python 3.5), list the installed Python packages, like this:

$ pip list | grep -i keras
Keras (1.1.0)

If you don’t see Keras, it means that the previous installation failed or is incomplete (this lib has this dependancies: numpy (1.11.2), PyYAML (3.12), scipy (0.18.1), six (1.10.0), and Theano (0.8.2).)

Consult the pip.log to see what’s wrong.

You can also display your Python path like this:

$ python3 -c 'import sys, pprint; pprint.pprint(sys.path)'
['',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python35.zip',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/plat-darwin',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/lib-dynload',
 '/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages']

Make sure the Keras library appears in the /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/site-packages path (the path is different on Ubuntu).

If not, try do uninstall it, and retry installation:

$ pip uninstall Keras

Use a virtualenv

It’s a bad idea to use and pollute your system-wide Python. I recommend using a virtualenv (see this guide).

The best usage is to create a virtualenv directory (in your home, for instance), and store your virtualenvs in:

cd virtualenv/
virtualenv -p python3.5 py-keras
source py-keras/bin/activate
pip install -q -U pip setuptools wheel

Then install Keras:

pip install keras

You get:

$ pip list
Keras (1.1.0)
numpy (1.11.2)
pip (8.1.2)
PyYAML (3.12)
scipy (0.18.1)
setuptools (28.3.0)
six (1.10.0)
Theano (0.8.2)
wheel (0.30.0a0)

But, you also need to install extra libraries, like Tensorflow:

$ python -c "import keras"
Using TensorFlow backend.
Traceback (most recent call last):
  ...
ImportError: No module named 'tensorflow'

The installation guide of TesnsorFlow is here: https://www.tensorflow.org/versions/r0.11/get_started/os_setup.html#pip-installation

Give unique class and different id for file input

           $("#tab-content").on('change',class,function()
               {
                  var id=$(this).attr('id');
                      $("#"+id).trigger(your function); 
               //for name of file input  $("#"+id).attr("name");
               });

class Child(SomeBaseClass):
    def __init__(self):
        SomeBaseClass.__init__(self)

This is fairly easy to understand.

class Child(SomeBaseClass):
    def __init__(self):
        super(Child, self).__init__()

Ok, what happens now if you use super(Child,self)?

When a Child instance is created, its MRO(Method Resolution Order) is in the order of (Child, SomeBaseClass, object) based on the inheritance. (assume SomeBaseClass doesn't have other parents except for the default object)

By passing Child, self, super searches in the MRO of the self instance, and return the proxy object next of Child, in this case it's SomeBaseClass, this object then invokes the __init__ method of SomeBaseClass. In other word, if it's super(SomeBaseClass,self), the proxy object that super returns would be object

For multi inheritance, the MRO could contain many classes, so basically super lets you decide where you want to start searching in the MRO.

I didn't mean to copy the same answer, that is why I didn't accept my own answer.

Actually when I add use DateTime in top of the controller solves this problem.

The following query will help to find out free space of tablespaces in MB:

select tablespace_name , sum(bytes)/1024/1024 from dba_free_space group by tablespacE_name order by 1;

Define your own parse format string to use.

string formatString = "yyyyMMddHHmmss";
string sample = "20100611221912";
DateTime dt = DateTime.ParseExact(sample,formatString,null);

In case you got a datetime having milliseconds, use the following formatString

string format = "yyyyMMddHHmmssfff"
string dateTime = "20140123205803252";
DateTime.ParseExact(dateTime ,format,CultureInfo.InvariantCulture);

Now you do not even need to think about the difference between these two because of Spacemacs. It is a community-driven Emacs distribution.

As it said,

The best editor is neither Emacs nor vim, It's Emacs and Vim.

Spacemacs combines the best from both Emacs and Vim, which make your life and job much easier.

See screenshot below,

_{(source: spacemacs.org)}

Here is a working example in both Javascript and jQuery:

http://jsfiddle.net/GuLYN/312/

//In jQuery
$("#calculate").click(function() {
    var num = parseFloat($("#textbox").val());
    var new_num = $("#textbox").val(num.toFixed(2));
});


// In javascript
document.getElementById('calculate').onclick = function() {
    var num = parseFloat(document.getElementById('textbox').value);
    var new_num = num.toFixed(2);
    document.getElementById('textbox').value = new_num;
};
?

It's impossible for both servers to listen on the same port at the same IP address: since a single socket can only be opened by a single process, only the first server configured for a certain IP/port combination will successfully bind, and the second one will fail.

You will thus need a workaround to achieve what you want. Easiest is probably to run Apache on your primary IP/port combination, and have it route requests for IIS (which should be configured for a different IP and/or port) to it using mod_rewrite.

Keep in mind that the alternative IP and port IIS runs on should be reachable to the clients connecting to your server: if you only have a single IP address available, you should take care to pick an IIS port that isn't generally blocked by firewalls (8080 might be a good option, or 443, even though you're running regular HTTP and not SSL)

P.S. Also, please note that you do need to modify the IIS default configuration using httpcfg before it will allow other servers to run on port 80 on any IP address on the same server: see Micky McQuade's answer for the procedure to do that...

STR_TO_DATE allows you to do this, and it has a format argument.

I have had this issue multiple times only in Windows I try these in the order usually.

1. npm install --force
2. Check if node_modules is set to read-only and remove if it is
3. Delete node_modules/
4. Check if any editor is opened that could have access to the root folder of the project
5. Reboot :(

Usually trying npm install after one of those steps will resolve it.

Its just to save a byte of data when we do javascript minification.

consider the below anonymous function

function (){}

To make the above as self invoking function we will generally change the above code as

(function (){}())

Now we added two extra characters (,) apart from adding () at the end of the function which necessary to call the function. In the process of minification we generally focus to reduce the file size. So we can also write the above function as

!function (){}()

Still both are self invoking functions and we save a byte as well. Instead of 2 characters (,) we just used one character !

This code will do what you're looking for. It's based on examples found here and here.

The autofmt_xdate() call is particularly useful for making the x-axis labels readable.

import numpy as np
from matplotlib import pyplot as plt

fig = plt.figure()

width = .35
ind = np.arange(len(OY))
plt.bar(ind, OY, width=width)
plt.xticks(ind + width / 2, OX)

fig.autofmt_xdate()

plt.savefig("figure.pdf")

If speed is your primary concern, then I'd simply go with

double r = (double)rand() / (double)RAND_MAX;

Just for completeness, since MySQL and Postgres have already been mentioned: With SQLite, use "pragma table_info()"

sqlite> pragma table_info('table_name');
cid         name        type        notnull     dflt_value  pk        
----------  ----------  ----------  ----------  ----------  ----------
0           id          integer     99                      1         
1           name                    0                       0         

S.Lott inserted a comment, but it should be an answer: see the same question.

EDIT

Since it wasn't as obvious as I intended it to be, here follows a verbatim copy of S.Lott's answer in the other question:

I'm a big fan of ARGO UML from Tigris.org. Draws nice pictures using standard UML notation. It does some code generation, but mostly Java classes, which isn't SQL DDL, so that may not be close enough to what you want to do.

You can look at the Data Modelling Tools list and see if anything there is better than Argo UML. Many of the items on this list are free or cheap.

Also, if you're using Eclipse or NetBeans, there are many design plug-ins, some of which may have the features you're looking for.

Here is another way to change DNS by using WMIC (Windows Management Instrumentation Command-line).

The commands must be run as administrator to apply.

Clear DNS servers:

wmic nicconfig where (IPEnabled=TRUE) call SetDNSServerSearchOrder ()

Set 1 DNS server:

wmic nicconfig where (IPEnabled=TRUE) call SetDNSServerSearchOrder ("8.8.8.8")

Set 2 DNS servers:

wmic nicconfig where (IPEnabled=TRUE) call SetDNSServerSearchOrder ("8.8.8.8", "8.8.4.4")

Set 2 DNS servers on a particular network adapter:

wmic nicconfig where "(IPEnabled=TRUE) and (Description = 'Local Area Connection')" call SetDNSServerSearchOrder ("8.8.8.8", "8.8.4.4")

Another example for setting the domain search list:

wmic nicconfig call SetDNSSuffixSearchOrder ("domain.tld")

or

View.inflate(context, layout, parent)

Include required imports and you can make ur decision in handleError method Error status will give the error code

import { HttpClient, HttpErrorResponse } from '@angular/common/http';
import {Observable, throwError} from "rxjs/index";
import { catchError, retry } from 'rxjs/operators';
import {ApiResponse} from "../model/api.response";
import { TaxType } from '../model/taxtype.model'; 

private handleError(error: HttpErrorResponse) {
if (error.error instanceof ErrorEvent) {
  // A client-side or network error occurred. Handle it accordingly.
  console.error('An error occurred:', error.error.message);
} else {
  // The backend returned an unsuccessful response code.
  // The response body may contain clues as to what went wrong,
  console.error(
    `Backend returned code ${error.status}, ` +
    `body was: ${error.error}`);
}
// return an observable with a user-facing error message
return throwError(
  'Something bad happened; please try again later.');
  };

  getTaxTypes() : Observable<ApiResponse> {
return this.http.get<ApiResponse>(this.baseUrl).pipe(
  catchError(this.handleError)
);
  }

var height = document.body.clientHeight;
var width = document.body.clientWidth;

But you can also do it in openssl (openssl enc command does it....), look at the BIO_f_base64() function

Some of it is native, the rest is available through libraries.

For example Datejs is a good international date library.

For the rest, it's just about language translation, and JavaScript is natively Unicode compatible (as well as all major browsers).

imgtag.group(0) or imgtag.group(). This returns the entire match as a string. You are not capturing anything else either.

rt.jar contains all of the compiled class files for the base Java Runtime environment. You should not be messing with this jar file.

For MacOS it is called classes.jar and located under /System/Library/Frameworks/<java_version>/Classes . Same not messing with it rule applies there as well :).

Use mutex solution:

using System;
using System.Windows.Forms;
using System.Threading;

namespace OneAndOnlyOne
{
static class Program
{
    static String _mutexID = " // generate guid"
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        Boolean _isNotRunning;
        using (Mutex _mutex = new Mutex(true, _mutexID, out _isNotRunning))
        {
            if (_isNotRunning)
            {
                Application.Run(new Form1());
            }
            else
            {
                MessageBox.Show("An instance is already running.");
                return;
            }
        }
    }

PHP HAS multithreading, its just not enabled by default, there is an extension called pthreads which does exactly that. You'll need php compiled with ZTS though. (Thread Safe) Links:

Checkout the -maxdepth flag of find

find . -maxdepth 1 -type d -exec ls -ld "{}" \;

Here I used 1 as max level depth, -type d means find only directories, which then ls -ld lists contents of, in long format.

I created a gem to make URI encoding stuff cleaner to use in your code. It takes care of binary encoding for you.

Run gem install uri-handler, then use:

require 'uri-handler'

str = "\x12\x34\x56\x78\x9a\xbc\xde\xf1\x23\x45\x67\x89\xab\xcd\xef\x12\x34\x56\x78\x9a".to_uri
# => "%124Vx%9A%BC%DE%F1%23Eg%89%AB%CD%EF%124Vx%9A"

It adds the URI conversion functionality into the String class. You can also pass it an argument with the optional encoding string you would like to use. By default it sets to encoding 'binary' if the straight UTF-8 encoding fails.

Alternatively if you want to grab the private and public keys from a PuTTY formated key file you can use puttygen on *nix systems. For most apt-based systems puttygen is part of the putty-tools package.

Outputting a private key from a PuTTY formated keyfile:

$ puttygen keyfile.pem -O private-openssh -o avdev.pvk

For the public key:

$ puttygen keyfile.pem -L

For anyone looking to use this and keep the 'click' functionality (as John Landheer mentions in his comment), you can do it with just a couple of modifications:

Add a couple of globals:

var clickms = 100;
var lastTouchDown = -1;

Then modify the switch statement from the original to this:

var d = new Date();
switch(event.type)
{
    case "touchstart": type = "mousedown"; lastTouchDown = d.getTime(); break;
    case "touchmove": type="mousemove"; lastTouchDown = -1; break;        
    case "touchend": if(lastTouchDown > -1 && (d.getTime() - lastTouchDown) < clickms){lastTouchDown = -1; type="click"; break;} type="mouseup"; break;
    default: return;
}

You may want to adjust 'clickms' to your tastes. Basically it's just watching for a 'touchstart' followed quickly by a 'touchend' to simulate a click.

tl;dr

LocalDate.parse( "2013-09-18" )

… and …

myLocalDate.toString()  // Example: 2013-09-18

java.time

The Question and other Answers are out-of-date. The troublesome old legacy date-time classes are now supplanted by the java.time classes.

ISO 8601

Your input string happens to comply with standard ISO 8601 format, YYYY-MM-DD. The java.time classes use ISO 8601 formats by default when parsing and generating string representations of date-time values. So no need to specify a formatting pattern.

LocalDate

The LocalDate class represents a date-only value without time-of-day and without time zone.

LocalDate ld = LocalDate.parse( "2013-09-18" );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

This will fix the problem:

aes.Padding = PaddingMode.Zeros;

string replace() function perfectly solves this problem:

string.replace(s, old, new[, maxreplace])

Return a copy of string s with all occurrences of substring old replaced by new. If the optional argument maxreplace is given, the first maxreplace occurrences are replaced.

>>> u'longlongTESTstringTEST'.replace('TEST', '?', 1)
u'longlong?stringTEST'

I've tried few methods from this question and they all failed on my CentOs, either because of the wrong repos or missing files.

The ZXing project provides a standalone barcode reader application which — via Android's intent mechanism — can be called by other applications who wish to integrate barcode scanning.

The easiest way to do this is to call the ZXing SCAN Intent from your application, like this:

public Button.OnClickListener mScan = new Button.OnClickListener() {
    public void onClick(View v) {
        Intent intent = new Intent("com.google.zxing.client.android.SCAN");
        intent.putExtra("SCAN_MODE", "QR_CODE_MODE");
        startActivityForResult(intent, 0);
    }
};

public void onActivityResult(int requestCode, int resultCode, Intent intent) {
    if (requestCode == 0) {
        if (resultCode == RESULT_OK) {
            String contents = intent.getStringExtra("SCAN_RESULT");
            String format = intent.getStringExtra("SCAN_RESULT_FORMAT");
            // Handle successful scan
        } else if (resultCode == RESULT_CANCELED) {
            // Handle cancel
        }
    }
}

Pressing the button linked to mScan would launch directly into the ZXing barcode scanner screen (or crash if ZXing isn't installed). Once a barcode has been recognised, you'll receive the result in your Activity, here in the contents variable.

To avoid the crashing and simplify things for you, ZXing have provided a utility class which you could integrate into your application to make the installation of ZXing smoother, by redirecting the user to the Android Market if they don't have it installed already.

Finally, if you want to integrate barcode scanning directly into your application without relying on having the separate ZXing application installed, well then it's an open source project and you can do so! :)

Edit: Somebody edited this guide into this answer (it sounds a bit odd, I can't vouch as to its accuracy, and I'm not sure why they're using Eclipse in 2015):

Step by step to setup zxing 3.2.1 in eclipse

1. Download zxing-master.zip from "https://github.com/zxing/zxing"
2. Unzip zxing-master.zip, Use eclipse to import "android" project in zxing-master
3. Download core-3.2.1.jar from "http://repo1.maven.org/maven2/com/google/zxing/core/3.2.1/"
4. Create "libs" folder in "android" project and paste cor-3.2.1.jar into the libs folder
5. Click on project: choose "properties" -> "Java Compiler" to change level to 1.7. Then click on "Android" change "Project build target" to android 4.4.2+, because using 1.7 requires compiling with Android 4.4
6. If "CameraConfigurationUtils.java" don't exist in "zxing-master/android/app/src/main/java/com/google/zxing/client/android/camera/". You can copy it from "zxing-master/android-core/src/main/java/com/google/zxing/client/android/camera/" and paste to your project.
7. Clean and build project. If your project show error about "switch - case", you should change them to "if - else".
8. Completed. Clean and build project. You can click on "Proprties" > "Android" > click on "Is Libraries" to use for your project.

1. Basic validation can be performed by choosing the type attribute of input elements. For example: <input type="email" /> <input type="URL" /> <input type="number" />

2. using pattern attribute like: <input type="text" pattern="[1-4]{5}" />

3. required attribute <input type="text" required />

4. maxlength: <input type="text" maxlength="20" />

5. min & max: <input type="number" min="1" max="4" />

In the lastest requests package, you can use json parameter in requests.post() method to send a json dict, and the Content-Type in header will be set to application/json. There is no need to specify header explicitly.

import requests

payload = {'key': 'value'}
requests.post(url, json=payload)

Try this:

u=open("url.txt","r")  
url=u.read().replace('\n','')  
print(url)  

I guess your end goal is to show Distinct (unique) values inside your original Pivot table.

For example you could have data set with OrderNumber, OrderDate, OrderItem, orderQty

First pivot table will show you OrderDate and sum of OrderQty and you probably want to see Count of unique orders in the same Pivot. You woudln't be able to do so within standard pivot table

If you want to do it, you would need Office 2016 (or perhaps pover Pivot might work). In office 2016 select your data > Insert > Pivot Table > choose tick "Add this data to the Data Model"

After that, you would be able to select grouping method as Distinct (Count)

Be careful with the select() function, because it's used both in the dplyr and MASS packages, so if MASS is loaded, select() may not work properly. To find out what packages are loaded, type sessionInfo() and look for it in the "other attached packages:" section. If it is loaded, type detach( "package:MASS", unload = TRUE ), and your select() function should work again.

So far this is working fine for me:

line-height: 100%;

This seems tailor-made for a collections.deque since you essentially have a FIFO (add to one end, remove from the other). However, even if you use a list you shouldn't be slicing twice; instead, you should probably just pop(0) from the list and append() the new item.

Here is an optimized deque-based implementation patterned after your original:

from collections import deque

def window(seq, n=2):
    it = iter(seq)
    win = deque((next(it, None) for _ in xrange(n)), maxlen=n)
    yield win
    append = win.append
    for e in it:
        append(e)
        yield win

In my tests it handily beats everything else posted here most of the time, though pillmuncher's tee version beats it for large iterables and small windows. On larger windows, the deque pulls ahead again in raw speed.

Access to individual items in the deque may be faster or slower than with lists or tuples. (Items near the beginning are faster, or items near the end if you use a negative index.) I put a sum(w) in the body of my loop; this plays to the deque's strength (iterating from one item to the next is fast, so this loop ran a a full 20% faster than the next fastest method, pillmuncher's). When I changed it to individually look up and add items in a window of ten, the tables turned and the tee method was 20% faster. I was able to recover some speed by using negative indexes for the last five terms in the addition, but tee was still a little faster. Overall I would estimate that either one is plenty fast for most uses and if you need a little more performance, profile and pick the one that works best.

I deleted the project without removing content. I then created a new Java project from an existing resource. Pointing at my SVN checkout root folder. This worked for me. Although, Chris' way would have been much quicker. That's good to note for future. Thanks!

If you meant just ABC as simple value, answer above is the one that works fine.

If you meant concatenation of values of rows that are not selected by your main query, you will need to use a subquery.

Something like this may work:

SELECT t1.col1, 
t1.col2, 
(SELECT GROUP_CONCAT(col2 SEPARATOR '') FROM  Table1 t2 WHERE t2.col1 != 0) as col3 
FROM Table1 t1
WHERE t1.col1 = 0;

Actual syntax maybe a bit off though

I hunted around for ages to find a decent easy solution to this and in the end found some ridiculously complicated CLR solutions so decided to write my own simple VB one. Simply create a new VB CLR project from the Database tab under Installed Templates, and then add a new SQL CLR VB User Defined Function. I renamed it to CLRGetFilesInDir.vb. Here's the code inside it...

Imports System
Imports System.Data
Imports System.Data.Sql
Imports System.Data.SqlTypes
Imports Microsoft.SqlServer.Server
Imports System.IO
-----------------------------------------------------------------------------
Public Class CLRFilesInDir
-----------------------------------------------------------------------------
<SqlFunction(FillRowMethodName:="FillRowFiles", IsDeterministic:=True, IsPrecise:=True, TableDefinition:="FilePath nvarchar(4000)")> _
Public Shared Function GetFiles(PathName As SqlString, Pattern As SqlString) As IEnumerable
    Dim FileNames As String()

    Try
    FileNames = Directory.GetFiles(PathName, Pattern, SearchOption.TopDirectoryOnly)
    Catch
        FileNames = Nothing
    End Try

    Return FileNames

End Function
-----------------------------------------------------------------------------
Public Shared Sub FillRowFiles(ByVal obj As Object, ByRef Val As SqlString)
    Val = CType(obj, String).ToString
End Sub

End Class

I also changed the Assembly Name in the Project Properties window to CLRExcelFiles, and the Default Namespace to CLRGetExcelFiles.

NOTE: Set the target framework to 3.5 if you are using anything less that SQL Server 2012.

Compile the project and then copy the CLRExcelFiles.dll from \bin\release to somewhere like C:\temp on the SQL Server machine, not your own.

In SSMS:-

CREATE ASSEMBLY <your assembly name in here - anything you like>
FROM 'C:\temp\CLRExcelFiles.dll';

CREATE FUNCTION dbo.fnGetFiles
(
@PathName NVARCHAR(MAX),
@Pattern NVARCHAR(MAX)
)
RETURNS TABLE (Val NVARCHAR(100))
AS
EXTERNAL NAME <your assembly name>."CLRGetExcelFiles.CLRFilesInDir".GetFiles;
GO

then call it

SELECT * FROM dbo.fnGetFiles('\\<SERVERNAME>\<$SHARE>\<folder>\' , '*.xls')

NOTE: Even though I changed the Permission Level to EXTERNAL_ACCESS on the SQLCLR tab under Project Properties, I still needed to run this every time I (re)created it.

ALTER ASSEMBLY [CLRFilesInDirAssembly] 
WITH PERMISSION_SET = EXTERNAL_ACCESS 
GO

and wullah! that should work.

Axios is a promise based HTTP client for the browser and node.js.

It offers automatic transforms for JSON data and it's the official recommendation from the Vue.js team when migrating from the 1.0 version which included a REST client by default.

Performing a GET request

// Make a request for a user with a given ID
axios.get('http://query.yahooapis.com/v1/publ...')
  .then(function (response) {
    console.log(response);
  })
  .catch(function (error) {
    console.log(error);
  });

Or even just axios(url) is enough as a GET request is the default.

The Python runstats Module is for just this sort of thing. Install runstats from PyPI:

pip install runstats

Runstats summaries can produce the mean, variance, standard deviation, skewness, and kurtosis in a single pass of data. We can use this to create your "running" version.

from runstats import Statistics

stats = [Statistics() for num in range(len(data[0]))]

for row in data:

    for index, val in enumerate(row):
        stats[index].push(val)

    for index, stat in enumerate(stats):
        print 'Index', index, 'mean:', stat.mean()
        print 'Index', index, 'standard deviation:', stat.stddev()

Statistics summaries are based on the Knuth and Welford method for computing standard deviation in one pass as described in the Art of Computer Programming, Vol 2, p. 232, 3rd edition. The benefit of this is numerically stable and accurate results.

Disclaimer: I am the author the Python runstats module.

Fairly late to this party, but I came across this issue myself today at work. Here is how I solved the issue.

I was accessing a 3rd party API to retrieve a list of books. The object returned a massive JSON object containing roughly 20+ fields, of which I only needed the ID as a List string object. I used linq on the dynamic object to retrieve the specific field I needed and then inserted it into my List string object.

dynamic content = JsonConvert.DeserializeObject(requestContent);
var contentCodes = ((IEnumerable<dynamic>)content).Where(p => p._id != null).Select(p=>p._id).ToList();

List<string> codes = new List<string>();

foreach (var code in contentCodes)
{
    codes.Add(code?.ToString());
}

Sub FnGetSheetsName()

    Dim mainworkBook As Workbook

    Set mainworkBook = ActiveWorkbook

    For i = 1 To mainworkBook.Sheets.Count

    'Either we can put all names in an array , here we are printing all the names in Sheet 2

    mainworkBook.Sheets("Sheet2").Range("A" & i) = mainworkBook.Sheets(i).Name

    Next i

End Sub

Yes, use the jQuery contains selector.

If anyone needs it, here is the same code snippet but for Xamarin.Android.

In SQL Developer you can right-click on the package body then select RUN. The 'Run PL/SQL' window will let you edit the PL/SQL Block. Clicking OK will give you a window pane titled 'Output Variables - Log' with an output variables tab. You can select your output variables on the left and the result is shown on the right side. Very handy and fast.

I've used Rapid with T-SQL and I think there was something similiar to this.

Writing your own delcare-begin-end script where you loop through the cursor, as with DCookie's example, is always a good exercise to do every now and then. It will work with anything and you will know that your code works.

SELECT col1,
  col2
FROM
  (SELECT rownum X,col_table1 FROM table1) T1
INNER JOIN
  (SELECT rownum Y, col_table2 FROM table2) T2
ON T1.X=T2.Y;

http://joda-time.sourceforge.net/quickstart.html

Each datetime class provides a variety of constructors. These include the Object constructor. This allows you to construct, for example, DateTime from the following objects:

* Date - a JDK instant
* Calendar - a JDK calendar
* String - in ISO8601 format
* Long - in milliseconds
* any Joda-Time datetime class

You can use awk:

ls -l | awk 'NR==2'

Update

The above code will not get what we want because of off-by-one error: the ls -l command's first line is the total line. For that, the following revised code will work:

ls -l | awk 'NR==3'

Opposite up is children(), but opposite in position is prepend(). Here a very good tutorial.

JAVA_HOME is a environment variable (in Unix terminologies), or a PATH variable (in Windows terminology). A lot of well behaving Java applications (which need the JDK/JRE) to run, looks up the JAVA_HOME variable for the location where the Java compiler/interpreter may be found.

tl;dr; Excel does all of this natively - use filters and or tables

(http://office.microsoft.com/en-gb/excel-help/filter-data-in-an-excel-table-HA102840028.aspx)

You can open excel programatically through an oledb connection and execute SQL on the tables within the worksheet.

But you can do everything you are asking to do with no formulas just filters.

1. click anywhere within the data you are looking at
2. go to data on the ribbon bar
3. select "Filter" its about the middle and looks like a funnel
   • you will have arrows on the tight hand side of each cell in the the first row of your table now
4. click the arrow on phone number and de-select blanks (last option)
5. click the arrow on last name and select a-z ordering (top option)

have a play around.. some things to note:

1. you can select the filtered rows and pasty them somewhere else
2. in the status bar on the left you will see how many rows meet you filter criteria out of the total number of rows. (e.g. 308 of 313 records found)
3. you can filter by color in excel 2010 on wards
4. Sometimes i create calculated columns that give statuses or cleaned versions of data you can then filter or sort by theses too. (e.g. like the formulae in the other answers)

DO it with filters unless you are going to do it a lot or you want to automate importing data somewhere or something.. but for completeness:

A c# option:

 OleDbConnection ExcelFile = new OleDbConnection( String.Format( "Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=\"Excel 12.0;HDR=YES\"", filename));
 ExcelFile.Open();

a handy place to start is to take a look at the schema as there may be more there than you think:

List<String> excelSheets = new List<string>();

// Add the sheet name to the string array.
foreach (DataRow row in dt.Rows) {
    string temp = row["TABLE_NAME"].ToString();
    if (temp[temp.Length - 1] == '$') {
         excelSheets.Add(row["TABLE_NAME"].ToString());
    }
}

then when you want to query a sheet:

 OleDbDataAdapter da = new OleDbDataAdapter("select * from [" + sheet + "]", ExcelFile);
 dt = new DataTable();
  da.Fill(dt);

NOTE - Use Tables in excel!:

Excel has "tables" functionality that make data behave more like a table.. this gives you some great benefits but is not going to let you do every type of query.

http://office.microsoft.com/en-gb/excel-help/overview-of-excel-tables-HA010048546.aspx

For tabular data in excel this is my default.. first thing i do is click into the data then select "format as table" from the home section on the ribbon. this gives you filtering, and sorting by default and allows you to access the table and fields by name (e.g. table[fieldname] ) this also allows aggregate functions on columns e.g. max and average

Say you have commit id 2 after commit 1 you would be able to run:

git diff 2 1 > mypatch.diff

where 2 and 1 are SHA hashes.

If you are testing this on your local WAMP you might need to set up the temporary folder for file uploads. You can do this in your PHP.ini file:

upload_tmp_dir = "c:\mypath\mytempfolder\"

You will need to grant permissions on the folder to allow the upload to take place - the permission you need to grant vary based on your operating system.

A handle can be anything from an integer index to a pointer to a resource in kernel space. The idea is that they provide an abstraction of a resource, so you don't need to know much about the resource itself to use it.

For instance, the HWND in the Win32 API is a handle for a Window. By itself it's useless: you can't glean any information from it. But pass it to the right API functions, and you can perform a wealth of different tricks with it. Internally you can think of the HWND as just an index into the GUI's table of windows (which may not necessarily be how it's implemented, but it makes the magic make sense).

EDIT: Not 100% certain what specifically you were asking in your question. This is mainly talking about pure C/C++.

Another, more humane way:

find /<directory> -newermt "-24 hours" -ls

or:

find /<directory> -newermt "1 day ago" -ls

or:

find /<directory> -newermt "yesterday" -ls

You should use raw_input to take a string input. then use islower method of str object.

s = raw_input('Type a word')
l = []
for c in s.strip():
    if c.islower():
        print c
        l.append(c)
print 'Total number of lowercase letters: %d'%(len(l) + 1)

Just do -

dir(s)

and you will find islower and other attributes of str

Here's the obligatory dplyr answer in case somebody wants to do this with the pipe.

test %>% 
    select(sort(names(.)))

I just found a solution to the problem here:

http://willcodeforcoffee.com/2007/01/31/cakephp-error-500-too-many-redirects/

The .htaccess file in webroot should look like:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>

instead of this:

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /projectname
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>

In order to solve it you need to add async defer to the script.

It should be like this:

<script src="https://maps.googleapis.com/maps/api/js?key=YOUR_API_KEY&callback=initMap"
    async defer></script>

See here the meaning of async defer.

Since you'll be calling a function from the main js file, you also want to make sure that this is after the one where you load the main script.

New is always used to allocate dynamic memory, which then has to be freed.

By doing the first option, that memory will be automagically freed when scope is lost.

Point p1 = Point(0,0); //This is if you want to be safe and don't want to keep the memory outside this function.

Point* p2 = new Point(0, 0); //This must be freed manually. with...
delete p2;

This is exactly what the OUTPUT clause in SQL Server 2005 onwards is excellent for.

EXAMPLE

CREATE TABLE [dbo].[test_table](
    [LockId] [int] IDENTITY(1,1) NOT NULL,
    [StartTime] [datetime] NULL,
    [EndTime] [datetime] NULL,
PRIMARY KEY CLUSTERED 
(
    [LockId] ASC
) ON [PRIMARY]
) ON [PRIMARY]

INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 07','2009 JUL 07')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 08','2009 JUL 08')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 09','2009 JUL 09')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 10','2009 JUL 10')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 11','2009 JUL 11')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 12','2009 JUL 12')
INSERT INTO test_table(StartTime, EndTime)
VALUES('2009 JUL 13','2009 JUL 13')

UPDATE test_table
    SET StartTime = '2011 JUL 01'
    OUTPUT INSERTED.* -- INSERTED reflect the value after the UPDATE, INSERT, or MERGE statement is completed 
WHERE
    StartTime > '2009 JUL 09'

Results in the following being returned

    LockId StartTime                EndTime
-------------------------------------------------------
4      2011-07-01 00:00:00.000  2009-07-10 00:00:00.000
5      2011-07-01 00:00:00.000  2009-07-11 00:00:00.000
6      2011-07-01 00:00:00.000  2009-07-12 00:00:00.000
7      2011-07-01 00:00:00.000  2009-07-13 00:00:00.000

In your particular case, since you cannot use aggregate functions with OUTPUT, you need to capture the output of INSERTED.* in a table variable or temporary table and count the records. For example,

DECLARE @temp TABLE (
  [LockId] [int],
  [StartTime] [datetime] NULL,
  [EndTime] [datetime] NULL 
)

UPDATE test_table
    SET StartTime = '2011 JUL 01'
    OUTPUT INSERTED.* INTO @temp
WHERE
    StartTime > '2009 JUL 09'


-- now get the count of affected records
SELECT COUNT(*) FROM @temp

Special thanks to the answer here for more-or-less the same question.

For me, all I needed was setlocale(LC_ALL, "en_US.UTF-8");

Then, I could use even raw wchar_t characters.

You can use the Visual Viewport API:

window.visualViewport.scale;

It is standard and works both on desktop and mobile: browser support.

Yes, there is: you can capture the echoed text using ob_start:

<?php function TestBlockHTML($replStr) {
    ob_start(); ?>
    <html>
    <body><h1><?php echo($replStr) ?></h1>
    </html>
<?php
    return ob_get_clean();
} ?>

(this was probably better as a comment, but got too long)

So, after reading this I was curious if pre-allocating was actually faster, because in theory it should be. However, this blog gave some tips advising against it http://www.html5rocks.com/en/tutorials/speed/v8/.

So still being unsure, I put it to the test. And as it turns out it seems to in fact be slower.

var time = Date.now();
var temp = [];
for(var i=0;i<100000;i++){
    temp[i]=i;
}
console.log(Date.now()-time);


var time = Date.now();
var temp2 = new Array(100000);
for(var i=0;i<100000;i++){
    temp2[i] = i;
}
console.log(Date.now()-time); 

This code yields the following after a few casual runs:

$ node main.js 
9
16
$ node main.js 
8
14
$ node main.js 
7
20
$ node main.js 
9

$ node main.js

>>> from datetime import date
>>> date.today().month

>>> date.today().year
2020
>>> date.today().day

Here's an example:

I'm writing a C# program that interfaces with a high-speed camera. The camera has its own driver that acquires images and loads them into the computer's memory for me automatically.

So when I'm ready to bring the latest image into my program to work with, the camera driver provides me with an IntPtr to where the image is ALREADY stored in physical memory, so I don't have to waste time/resources creating another block of memory to store an image that's in memory already. The IntPtr just shows me where the image already is.

<style type="text/css">
.container_box{
    text-align:center
}
.content{
    padding:10px;
    background:#ff0000;
    color:#ffffff;

}

use span istead of the inner divs

<div class="container_box">
   <span class="content">Hello</span>
</div>

In View Replace this:

@Html.DisplayFor(Model => Model.AuditDate.Value.ToShortDateString())

With:

@if(@Model.AuditDate.Value != null){@Model.AuditDate.Value.ToString("dd/MM/yyyy")}
else {@Html.DisplayFor(Model => Model.AuditDate)}

Explanation: If the AuditDate value is not null then it will format the date to dd/MM/yyyy, otherwise leave it as it is because it has no value.

I found another solution. It's a bit hacky but its widely available in angular2 world.

Since *ngIf directive removes the form and recreates it, one can simply add an *ngIf to the form and bind it to some sort of formSuccessfullySentvariable. => This will recreate the form and therefore reset the input control statuses.

Of course, you have to clear the model variables also. I found it convenient to have a specific model class for my form fields. This way i can reset all fields as simple as creating a new instance of this model class. :)

Parameters are the variables received by a function.Hence they are visible in function declaration.They contain the variable name with their data type. Arguments are actual values which are passed to another function. thats why we can see them in function call. They are just values without their datatype

To install the plug-in, unzip the file into the Eclipse installation directory (or the plug-in directory depending on how the plug-in is packaged). The plug-in will not appear until you have restarted your workspace (Reboot Eclipse).

Instead of BSD sed, i use perl:

ct@MBA45:~$ python -c "print('\t\t\thi')" |perl -0777pe "s/\t/ /g"
   hi

For the complete system you can add the Microsoft.VisualBasic Framework as a reference;

 Console.WriteLine("You have {0} bytes of RAM",
        new Microsoft.VisualBasic.Devices.ComputerInfo().TotalPhysicalMemory);
        Console.ReadLine();

There's a function std::reverse in the algorithm header for this purpose.

#include <vector>
#include <algorithm>

int main() {
  std::vector<int> a;
  std::reverse(a.begin(), a.end());
  return 0;
}

Try this out:

public static char[] myABCs = {'a', 'b', 'c'};
public static int numInput;
static Scanner in = new Scanner(System.in);

public static void main(String[] args) {
    System.out.print("Enter Number of Times to repeat: ");
    numInput = in.nextInt();
    repeatArray(numInput);
}

public static int repeatArray(int y) {
    for (int a = 0; a < y; a++) {
        for (int b = 0; b < myABCs.length; b++) {
            System.out.print(myABCs[b]);                
        }
        System.out.print(" ");
    }
    return y;
}

You can declare trk by the following ways : - either

trk : [{
    lat : String,
    lng : String
     }]

or

trk : { type : Array , "default" : [] }

In the second case during insertion make the object and push it into the array like

db.update({'Searching criteria goes here'},
{
 $push : {
    trk :  {
             "lat": 50.3293714,
             "lng": 6.9389939
           } //inserted data is the object to be inserted 
  }
});

or you can set the Array of object by

db.update ({'seraching criteria goes here ' },
{
 $set : {
          trk : [ {
                     "lat": 50.3293714,
                     "lng": 6.9389939
                  },
                  {
                     "lat": 50.3293284,
                     "lng": 6.9389634
                  }
               ]//'inserted Array containing the list of object'
      }
});

The easisest way to get a posted json string, for example, is to read the contents of 'php://input' and then decode it. For example i had a simple Zend route:

'save-json' => array(
'type' => 'Zend\Mvc\Router\Http\Segment',
            'options' => array(
                'route'    => '/save-json/',
                'defaults' => array(
                    'controller' => 'CDB\Controller\Index',
                    'action'     => 'save-json',
                ),
            ),
        ),

and i wanted to post data to it using Angular's $http.post. The post was fine but the retrive method in Zend

$this->params()->fromPost('paramname'); 

didn't get anything in this case. So my solution was, after trying all kinds of methods like $_POST and the other methods stated above, to read from 'php://':

$content = file_get_contents('php://input');
print_r(json_decode($content));

I got my json array in the end. Hope this helps.

ng-init is a directive that can be placed inside div's, span's, whatever, whereas onload is an attribute specific to the ng-include directive that functions as an ng-init. To see what I mean try something like:

<span onload="a = 1">{{ a }}</span>
<span ng-init="b = 2">{{ b }}</span>

You'll see that only the second one shows up.

An isolated scope is a scope which does not prototypically inherit from its parent scope. In laymen's terms if you have a widget that doesn't need to read and write to the parent scope arbitrarily then you use an isolate scope on the widget so that the widget and widget container can freely use their scopes without overriding each other's properties.

Try the following code:

//...
By mySelector = By.xpath("/html/body/div[1]/div/section/div/div[2]/form[1]/div/ul/li");
List<WebElement> myElements = driver.findElements(mySelector);
for(WebElement e : myElements) {
  System.out.println(e.getText());
}

It will returns with the whole content of the <li> tags, like:

<a class="extra">Vše</a> (950)</li>

But you can easily get the number now from it, for example by using split() and/or substring().

Automatically not split data to multi pages. You may split manually.

If your ( rowCount * rowHeight ) > 420mm ( A3 Height in mm ) add new page function. ( Sorry I can't edit your code without run ) After add new page leftMargin, topMargin = 0; ( start over ) I added sample code with yours. I hope it's right.

else {
    doc.margins = 1;
    doc.setFont("Times  ");
    doc.setFontType("normal ");
    doc.setFontSize(11);
    if ( rowCount * rowHeight > 420 ) {
        doc.addPage();
        rowCount = 3; // skip 1 and 2 above
    } else {
        // now rowcount = 3 ( top of new page for 3 )
        // j is your x axis cell index ( j start from 0 on $.each function ) or you can add cellCount like rowCount and replace with
        // rowcount is your y axis cell index
        left = ( ( j ) * ( cellWidth + leftMargin );
        top = ( ( rowcount - 3 ) * ( rowHeight + topMargin );
        doc.cell( leftMargin, top, cellWidth, rowHeight, cellContent, i);
        // 1st=left margin    2nd parameter=top margin,     3rd=row cell width      4th=Row height
    }
}

Here is the approach I follow whenever I see this type of error:

1. One way to debug this issue is by first taking whatever response is coming as String.class then applying Gson().fromJson(StringResp.body(), MyDTO.class). It will still fail most probably but this time it will throw the fields which are creating this error to happen in first place. Post the modification, we can use the previous approach as usual.

ResponseEntity<String> respStr = restTemplate.exchange(URL,HttpMethod.GET, entity, String.class);
Gson g = new Gson();

The below step will throw error with the fields which is causing the issue

MyDTO resp = g.fromJson(respStr.getBody(), MyDTO.class);

I don't have the error message with me but it will point to the field which is problematic and the reason for it. Resolve those and try again with previous approach.

If you are using WebApi, HttpResponseMessage is a more elegant way to do it

public HttpResponseMessage Get()
{
    return Request.CreateResponse(HttpStatusCode.OK, ListOfMyObject);
}

I too got similar error when i misplaced the code

text=(TextView)findViewById(R.id.text);// this line has to be below setcontentview
setContentView(R.layout.activity_my_otype);
//this is the correct place
text.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            }
    });

I got it working on placing the code in right order as shown below

setContentView(R.layout.activity_my_otype);
text=(TextView)findViewById(R.id.text);
 text.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            }
    });

Jon Skeets answer is right and has deserved my upvote, just adding this slightly different solution for completeness:

import static java.time.temporal.TemporalAdjusters.lastDayOfMonth;

LocalDate initial = LocalDate.of(2014, 2, 13);
LocalDate start = initial.withDayOfMonth(1);
LocalDate end = initial.with(lastDayOfMonth());

To move from c drive to other drive(D or E)use this command----->

cd "your path" Now hit enter. Check your path using $pwd. Your path has been change from one directory to other.

Ex---> cd "D:\WEB_DEV\HTML_CSS_projects\TouristVisitors_LandingPage". note - this is my path, your path should be different.

The best is QSpinBox.

And for a double value use QDoubleSpinBox.

QSpinBox myInt;
myInt.setMinimum(-5);
myInt.setMaximum(5);
myInt.setSingleStep(1);// Will increment the current value with 1 (if you use up arrow key) (if you use down arrow key => -1)
myInt.setValue(2);// Default/begining value
myInt.value();// Get the current value
//connect(&myInt, SIGNAL(valueChanged(int)), this, SLOT(myValueChanged(int)));

You could use this code:

abc_KeyDown(abc, new KeyEventArgs(Keys.Enter));

You could use .data():

$("#element").click(function(){
    $(this).data('clicked', true);
});

and then check it with:

if($('#element').data('clicked')) {
    alert('yes');
}

To get a better answer you need to provide more information.

Update:

Based on your comment, I understand you want something like:

$("#element").click(function(){
    var $this = $(this);
    if($this.data('clicked')) {
        func(some, other, parameters);
    }
    else {
        $this.data('clicked', true);
        func(some, parameter);
    }
});

For me, often times this is the only reason some code requires Java 6 to compile. Not sure if it's worth it.

You can look here Can the key in a Java property include a blank character?

for escape equal '=' \u003d

table.whereclause=where id=100

key:[table.whereclause] value:[where id=100]

table.whereclause\u003dwhere id=100

key:[table.whereclause=where] value:[id=100]

table.whereclause\u003dwhere\u0020id\u003d100

key:[table.whereclause=where id=100] value:[]

I was looking for a code snippet that performs well and is simple to customise. Threaded trees are not “simple”. Double stack solution requires O(n) memory. LeetCode solution and solution by tcb have extra checks and pushes...

Here is one classic algorithm translated into C that worked for me:

void postorder_traversal(TreeNode *p, void (*visit)(TreeNode *))
{
    TreeNode   *stack[40];      // simple C stack, no overflow check
    TreeNode  **sp = stack;
    TreeNode   *last_visited = NULL;

    for (; p != NULL; p = p->left)
        *sp++ = p;

    while (sp != stack) {
        p = sp[-1];
        if (p->right == NULL || p->right == last_visited) {
            visit(p);
            last_visited = p;
            sp--;
        } else {
            for (p = p->right; p != NULL; p = p->left)
                *sp++ = p;
        }
    }
}

IMHO this algorithm is easier to follow than well performing and readable wikipedia.org / Tree_traversal pseudocode. For glorious details see answers to binary tree exercises in Knuth’s Volume 1.

You'll want to use a number of layout managers to help you achieve the basic results you want.

Check out A Visual Guide to Layout Managers for a comparision.

You could use a GridBagLayout but that's one of the most complex (and powerful) layout managers available in the JDK.

You could use a series of compound layout managers instead.

I'd place the graphics component and text area on a single JPanel, using a BorderLayout, with the graphics component in the CENTER and the text area in the SOUTH position.

I'd place the text field and button on a separate JPanel using a GridBagLayout (because it's the simplest I can think of to achieve the over result you want)

I'd place these two panels onto a third, master, panel, using a BorderLayout, with the first panel in the CENTER and the second at the SOUTH position.

But that's me

My site is hosted on MochaHost, i had a tough time to setup the .htaccess file so that i can remove the index.php from my urls. However, after some googling, i combined the answer on this thread and other answers. My final working .htaccess file has the following contents:

<IfModule mod_rewrite.c>
    # Turn on URL rewriting
    RewriteEngine On

    # If your website begins from a folder e.g localhost/my_project then 
    # you have to change it to: RewriteBase /my_project/
    # If your site begins from the root e.g. example.local/ then
    # let it as it is
    RewriteBase /

    # Protect application and system files from being viewed when the index.php is missing
    RewriteCond $1 ^(application|system|private|logs)

    # Rewrite to index.php/access_denied/URL
    RewriteRule ^(.*)$ index.php/access_denied/$1 [PT,L]

    # Allow these directories and files to be displayed directly:
    RewriteCond $1 ^(index\.php|robots\.txt|favicon\.ico|public|app_upload|assets|css|js|images)

    # No rewriting
    RewriteRule ^(.*)$ - [PT,L]

    # Rewrite to index.php/URL
    RewriteRule ^(.*)$ index.php?/$1 [PT,L]
</IfModule>

You simply don't call the function.

>>>def x():
>>>    print(20)
>>>y = x
>>>y()
20

The brackets tell python that you are calling the function, so when you put them there, it calls the function and assigns y the value returned by x (which in this case is None).

As @Pepijn commented on @Druska 's answer, on ubuntu 13.04 x64, there is no need to use lib32z1-dev, zlib1g-dev is enough:

sudo apt-get install libxml2-dev libxslt-dev python-dev zlib1g-dev

Use an object (key/value pairs, the nearest JavaScript has to an associative array) for this and not the array object. Other than that, I believe that is the most elegant way

var foo = {};
foo['alfa'] = "first item";
foo['beta'] = "second item";

for (var key in foo) {
        console.log(key);
}

Note: JavaScript doesn't guarantee any particular order for the properties. So you cannot expect the property that was defined first to appear first, it might come last.

EDIT:

In response to your comment, I believe that this article best sums up the cases for why arrays in JavaScript should not be used in this fashion -

• "Associative Arrays" considered Harmful

It appears that you can throw only RuntimeException from the method orElseThrow. Otherwise you will get an error message like MyException cannot be converted to java.lang.RuntimeException

Update:- This was an issue with an older version of JDK. I don't see this issue with the latest versions.

Initially define a function pointer array which takes a void and returns a void.

Assuming that your function is taking a void and returning a void.

typedef void (*func_ptr)(void);

Now you can use this to create function pointer variables of such functions.

Like below:

func_ptr array_of_fun_ptr[3];

Now store the address of your functions in the three variables.

array_of_fun_ptr[0]= &A;
array_of_fun_ptr[1]= &B;
array_of_fun_ptr[2]= &C;

Now you can call these functions using function pointers as below:

some_a=(*(array_of_fun_ptr[0]))();
some_b=(*(array_of_fun_ptr[1]))();
some_c=(*(array_of_fun_ptr[2]))();

For normal DateTimes, if you don't initialize them at all then they will match DateTime.MinValue, because it is a value type rather than a reference type.

You can also use a nullable DateTime, like this:

DateTime? MyNullableDate;

Or the longer form:

Nullable<DateTime> MyNullableDate;

And, finally, there's a built in way to reference the default of any type. This returns null for reference types, but for our DateTime example it will return the same as DateTime.MinValue:

default(DateTime)

or, in more recent versions of C#,

default

You'll first need to separate your numpy array into two separate arrays containing x and y values.

x = [1, 2, 3, 9]
y = [1, 4, 1, 3]

curve_fit also requires a function that provides the type of fit you would like. For instance, a linear fit would use a function like

def func(x, a, b):
    return a*x + b

scipy.optimize.curve_fit(func, x, y) will return a numpy array containing two arrays: the first will contain values for a and b that best fit your data, and the second will be the covariance of the optimal fit parameters.

Here's an example for a linear fit with the data you provided.

import numpy as np
from scipy.optimize import curve_fit

x = np.array([1, 2, 3, 9])
y = np.array([1, 4, 1, 3])

def fit_func(x, a, b):
    return a*x + b

params = curve_fit(fit_func, x, y)

[a, b] = params[0]

This code will return a = 0.135483870968 and b = 1.74193548387

Here's a plot with your points and the linear fit... which is clearly a bad one, but you can change the fitting function to obtain whatever type of fit you would like.

Another way to do this without revert (traces of undo):

Don't do it if someone else has pushed other commits

Create a backup of your branch, being in your branch my-branch. So in case something goes wrong, you can restart the process without losing any work done.

git checkout -b my-branch-temp

Go back to your branch.

git checkout my-branch

Reset, to discard your last commit (to undo it):

git reset --hard HEAD^

Remove the branch on remote (ex. origin remote).

git push origin :my-branch

Repush your branch (without the unwanted commit) to the remote.

git push origin my-branch

Done!

I hope that helps! ;)

I usually use the Fusion Log Viewer (Fuslogvw.exe from a Visual Studio command prompt or Fusion Log Viewer from the start menu) - my standard setup is:

• Open Fusion Log Viewer as administrator
• Click settings
• Check the Enable custom log path checkbox
• Enter the location you want logs to get written to, for example, c:\FusionLogs (Important: make sure that you have actually created this folder in the file system.)
• Make sure that the right level of logging is on (I sometimes just select Log all binds to disk just to make sure things are working right)
• Click OK
• Set the log location option to Custom

Remember to turn of logging off once you're done!

(I just posted this on a similar question - I think it's relevant here too.)

I am using Bootstrap v3.3.4 and using the code:

Output is: 16-07-2015

Note: only need "yy" for full year.

If you are using C#, you do not need to escape it.

When to use extends and super

Wildcards are most useful in method parameters. They allow for the necessary flexibility in method interfaces.

People are often confused when to use extends and when to use super bounds. The rule of thumb is the get-put principle. If you get something from a parametrized container, use extends.

int totalFuel(List<? extends Vehicle> list) {
int total = 0;
for(Vehicle v : list) {
    total += v.getFuel();
}
return total;}

The method totalFuel gets Vehicles from the list, asks them about how much fuel they have, and computes the total. If you put objects into a parameterized container, use super.

int totalValue(Valuer<? super Vehicle> valuer) {
int total = 0;
for(Vehicle v : vehicles) {
    total += valuer.evaluate(v);
}
return total;}

The method totalValue puts Vehicles into the Valuer. It's useful to know that extends bound is much more common than super.

In jQuery:

To check the checkbox:

$("#checkboxid").attr("checked","checked");

To uncheck the checkbox:

$("#checkboxid").removeAttr("checked");

The other answers hint at the solution and point you to documentation that after further digging will get you to this answer. Jukka K. Korpela has the reason this is the correct answer, basically I followed his link and then looked up the jQuery docs to get to that result. Just figured I'd save future people who find this article those extra steps.

Try umount -f /mnt/share. Works OK with NFS, never tried with cifs.

Also, take a look at autofs, it will mount the share only when accessed, and will unmount it afterworlds.

There is a good tutorial at www.howtoforge.net

This work for me

$('#mySelect option:contains(' + value + ')').attr('selected', 'selected');

I was parsing JSON from a REST API call and got this error. It turns out the API had become "fussier" (eg about order of parameters etc) and so was returning malformed results. Check that you are getting what you expect :)

From PostreSQL 9.2 Range Types are supported. So you can write this like:

SELECT user_id
FROM user_logs
WHERE '[2014-02-01, 2014-03-01]'::daterange @> login_date

this should be more efficient than the string comparison

initialize the Session class in the constructor of controller using

$this->load->library('session');

for example :

 function __construct()
   {
    parent::__construct();
    $this->load->model('user','',TRUE);
    $this->load->model('user_activity','',TRUE);
    $this->load->library('session');
   }

The ajax is going to be a javascript snippet that passes information to a small php file that does what you want. So in your page, instead of all that php, you want a little javascript, preferable jquery:

function fun()
{
    $.get('\addEmail.php', {email : $(this).val()}, function(data) {
        //here you would write the "you ve been successfully subscribed" div
    });
}

also you input would have to be:

<input type="button" value="subscribe" class="submit" onclick="fun();" />

last the file addEmail.php should look something like:

mysql_connect("localhost","root","");
mysql_select_db("eciticket_db");

error_reporting(E_ALL && ~E_NOTICE);

$email=mysql_real_escape_string($_GET['email']);
$sql="INSERT INTO newsletter_email(email) VALUES ('$email')";
$result=mysql_query($sql);
if($result){
echo "You have been successfully subscribed.";
}
 if(!$sql)
die(mysql_error());

mysql_close();

Also sergey is right, you should use mysqli. That's not everything, but enough to get you started.

WPF: System.Windows.Clipboard (PresentationCore.dll)

Winforms: System.Windows.Forms.Clipboard

Both have a static SetText method.

Perl approach:

There are multiple versions of the echo command, with different behaviors. Apparently the shell used for your script uses a version that doesn't recognize -n.

The printf command has much more consistent behavior. echo is fine for simple things like echo hello, but I suggest using printf for anything more complicated.

What system are you on, and what shell does your script use?

Maybe this small Typescript code example will help.

private getAccount(id: Id) : Account {
    let account = Account.empty();
    this.repository.get(id)
        .then(res => account = res)
        .catch(e => Notices.results(e));
    return account;
}

Here the repository.get(id) returns a Promise<Account>. I assign it to the variable account within the then statement.

   p_errcode        OUT   NUMBER,
   p_errmesg        OUT   VARCHAR2,

AS
   v_param0   VARCHAR2 (30) := '0.25,2.25,33.689, abc, 99';
   v_param1   VARCHAR2 (30) := '2.65,66.32, abc-def, 21.5';

                  )
           VALUES (i.COLUMN_VALUE
                  );
   END LOOP;

   FOR i IN (SELECT COLUMN_VALUE
               FROM TABLE (SPLIT (v_param1, ',')))
   LOOP
      INSERT INTO tempo

The most visible immediate difference in older versions of Java would be the memory allocated to a -client as opposed to a -server application. For instance, on my Linux system, I get:

$ java -XX:+PrintFlagsFinal -version 2>&1 | grep -i -E 'heapsize|permsize|version'
uintx AdaptivePermSizeWeight               = 20               {product}
uintx ErgoHeapSizeLimit                    = 0                {product}
uintx InitialHeapSize                     := 66328448         {product}
uintx LargePageHeapSizeThreshold           = 134217728        {product}
uintx MaxHeapSize                         := 1063256064       {product}
uintx MaxPermSize                          = 67108864         {pd product}
uintx PermSize                             = 16777216         {pd product}
java version "1.6.0_24"

as it defaults to -server, but with the -client option I get:

$ java -client -XX:+PrintFlagsFinal -version 2>&1 | grep -i -E 'heapsize|permsize|version'
uintx AdaptivePermSizeWeight               = 20               {product}
uintx ErgoHeapSizeLimit                    = 0                {product}
uintx InitialHeapSize                     := 16777216         {product}
uintx LargePageHeapSizeThreshold           = 134217728        {product}
uintx MaxHeapSize                         := 268435456        {product}
uintx MaxPermSize                          = 67108864         {pd product}
uintx PermSize                             = 12582912         {pd product}
java version "1.6.0_24"

so with -server most of the memory limits and initial allocations are much higher for this java version.

These values can change for different combinations of architecture, operating system and jvm version however. Recent versions of the jvm have removed flags and re-moved many of the distinctions between server and client.

Remember too that you can see all the details of a running jvm using jvisualvm. This is useful if you have users who or modules which set JAVA_OPTS or use scripts which change command line options. This will also let you monitor, in real time, heap and permgen space usage along with lots of other stats.

Here is simple example. A contact has one to many associated phone numbers. When a contact is deleted, I want all its associated phone numbers to also be deleted, so I use ON DELETE CASCADE. The one-to-many/many-to-one relationship is implemented with by the foreign key in the phone_numbers.

CREATE TABLE contacts
 (contact_id BIGINT AUTO_INCREMENT NOT NULL,
 name VARCHAR(75) NOT NULL,
 PRIMARY KEY(contact_id)) ENGINE = InnoDB;

CREATE TABLE phone_numbers
 (phone_id BIGINT AUTO_INCREMENT NOT NULL,
  phone_number CHAR(10) NOT NULL,
 contact_id BIGINT NOT NULL,
 PRIMARY KEY(phone_id),
 UNIQUE(phone_number)) ENGINE = InnoDB;

ALTER TABLE phone_numbers ADD FOREIGN KEY (contact_id) REFERENCES \
contacts(contact_id) ) ON DELETE CASCADE;

By adding "ON DELETE CASCADE" to the foreign key constraint, phone_numbers will automatically be deleted when their associated contact is deleted.

INSERT INTO table contacts(name) VALUES('Robert Smith');
INSERT INTO table phone_numbers(phone_number, contact_id) VALUES('8963333333', 1);
INSERT INTO table phone_numbers(phone_number, contact_id) VALUES('8964444444', 1);

Now when a row in the contacts table is deleted, all its associated phone_numbers rows will automatically be deleted.

DELETE TABLE contacts as c WHERE c.id=1; /* delete cascades to phone_numbers */

To achieve the same thing in Doctrine, to get the same DB-level "ON DELETE CASCADE" behavoir, you configure the @JoinColumn with the onDelete="CASCADE" option.

If you now do

you will see that the same SQL will be generated as in the first, raw-SQL example

Let's say you want to pass a prop to a child component and that prop is a boolean that will determine if the checkbox is checked or not, then you have to pass the boolean value to the v-bind:checked="booleanValue" or the shorter way :checked="booleanValue", for example:

<input
    id="checkbox"
    type="checkbox"
    :value="checkboxVal"
    :checked="booleanValue"
    v-on:input="checkboxVal = $event.target.value"
/>

That should work and the checkbox will display the checkbox with it's current boolean state (if true checked, if not unchecked).

The most reliable way I've found to display the local time of a city or location is by tapping into a Time Zone API such as Google Time Zone API. It returns the correct time zone, and more importantly, Day Light Savings Time offset of any location, which just using JavaScript's Date() object cannot be done as far as I'm aware. There's a good tutorial on using the API to get and display the local time here:

var loc = '35.731252, 139.730291' // Tokyo expressed as lat,lng tuple
var targetDate = new Date() // Current date/time of user computer
var timestamp = targetDate.getTime() / 1000 + targetDate.getTimezoneOffset() * 60 // Current UTC date/time expressed as seconds since midnight, January 1, 1970 UTC
var apikey = 'YOUR_TIMEZONE_API_KEY_HERE'
var apicall = 'https://maps.googleapis.com/maps/api/timezone/json?location=' + loc + '&timestamp=' + timestamp + '&key=' + apikey

var xhr = new XMLHttpRequest() // create new XMLHttpRequest2 object
xhr.open('GET', apicall) // open GET request
xhr.onload = function() {
  if (xhr.status === 200) { // if Ajax request successful
    var output = JSON.parse(xhr.responseText) // convert returned JSON string to JSON object
    console.log(output.status) // log API return status for debugging purposes
    if (output.status == 'OK') { // if API reports everything was returned successfully
      var offsets = output.dstOffset * 1000 + output.rawOffset * 1000 // get DST and time zone offsets in milliseconds
      var localdate = new Date(timestamp * 1000 + offsets) // Date object containing current time of Tokyo (timestamp + dstOffset + rawOffset)
      console.log(localdate.toLocaleString()) // Display current Tokyo date and time
    }
  } else {
    alert('Request failed.  Returned status of ' + xhr.status)
  }
}
xhr.send() // send request

It seems like you are asking about the difference between the data model and the domain model – the latter is where you can find the business logic and entities as perceived by your end user, the former is where you actually store your data.

Furthermore, I've interpreted the 3rd part of your question as: how to notice failure to keep these models separate.

These are two very different concepts and it's always hard to keep them separate. However, there are some common patterns and tools that can be used for this purpose.

About the Domain Model

The first thing you need to recognize is that your domain model is not really about data; it is about actions and questions such as "activate this user", "deactivate this user", "which users are currently activated?", and "what is this user's name?". In classical terms: it's about queries and commands.

Thinking in Commands

Let's start by looking at the commands in your example: "activate this user" and "deactivate this user". The nice thing about commands is that they can easily be expressed by small given-when-then scenario's:

given an inactive user
when the admin activates this user
then the user becomes active
and a confirmation e-mail is sent to the user
and an entry is added to the system log
(etc. etc.)

Such scenario's are useful to see how different parts of your infrastructure can be affected by a single command – in this case your database (some kind of 'active' flag), your mail server, your system log, etc.

Such scenario's also really help you in setting up a Test Driven Development environment.

And finally, thinking in commands really helps you create a task-oriented application. Your users will appreciate this :-)

Expressing Commands

Django provides two easy ways of expressing commands; they are both valid options and it is not unusual to mix the two approaches.

The service layer

The service module has already been described by @Hedde. Here you define a separate module and each command is represented as a function.

services.py

def activate_user(user_id):
    user = User.objects.get(pk=user_id)

    # set active flag
    user.active = True
    user.save()

    # mail user
    send_mail(...)

    # etc etc

Using forms

The other way is to use a Django Form for each command. I prefer this approach, because it combines multiple closely related aspects:

• execution of the command (what does it do?)
• validation of the command parameters (can it do this?)
• presentation of the command (how can I do this?)

forms.py

class ActivateUserForm(forms.Form):

    user_id = IntegerField(widget = UsernameSelectWidget, verbose_name="Select a user to activate")
    # the username select widget is not a standard Django widget, I just made it up

    def clean_user_id(self):
        user_id = self.cleaned_data['user_id']
        if User.objects.get(pk=user_id).active:
            raise ValidationError("This user cannot be activated")
        # you can also check authorizations etc. 
        return user_id

    def execute(self):
        """
        This is not a standard method in the forms API; it is intended to replace the 
        'extract-data-from-form-in-view-and-do-stuff' pattern by a more testable pattern. 
        """
        user_id = self.cleaned_data['user_id']

        user = User.objects.get(pk=user_id)

        # set active flag
        user.active = True
        user.save()

        # mail user
        send_mail(...)

        # etc etc

Thinking in Queries

You example did not contain any queries, so I took the liberty of making up a few useful queries. I prefer to use the term "question", but queries is the classical terminology. Interesting queries are: "What is the name of this user?", "Can this user log in?", "Show me a list of deactivated users", and "What is the geographical distribution of deactivated users?"

Before embarking on answering these queries, you should always ask yourself this question, is this:

• a presentational query just for my templates, and/or
• a business logic query tied to executing my commands, and/or
• a reporting query.

Presentational queries are merely made to improve the user interface. The answers to business logic queries directly affect the execution of your commands. Reporting queries are merely for analytical purposes and have looser time constraints. These categories are not mutually exclusive.

The other question is: "do I have complete control over the answers?" For example, when querying the user's name (in this context) we do not have any control over the outcome, because we rely on an external API.

Making Queries

The most basic query in Django is the use of the Manager object:

User.objects.filter(active=True)

Of course, this only works if the data is actually represented in your data model. This is not always the case. In those cases, you can consider the options below.

Custom tags and filters

The first alternative is useful for queries that are merely presentational: custom tags and template filters.

template.html

<h1>Welcome, {{ user|friendly_name }}</h1>

template_tags.py

@register.filter
def friendly_name(user):
    return remote_api.get_cached_name(user.id)

Query methods

If your query is not merely presentational, you could add queries to your services.py (if you are using that), or introduce a queries.py module:

queries.py

def inactive_users():
    return User.objects.filter(active=False)


def users_called_publysher():
    for user in User.objects.all():
        if remote_api.get_cached_name(user.id) == "publysher":
            yield user 

Proxy models

Proxy models are very useful in the context of business logic and reporting. You basically define an enhanced subset of your model. You can override a Manager’s base QuerySet by overriding the Manager.get_queryset() method.

models.py

class InactiveUserManager(models.Manager):
    def get_queryset(self):
        query_set = super(InactiveUserManager, self).get_queryset()
        return query_set.filter(active=False)

class InactiveUser(User):
    """
    >>> for user in InactiveUser.objects.all():
    …        assert user.active is False 
    """

    objects = InactiveUserManager()
    class Meta:
        proxy = True

Query models

For queries that are inherently complex, but are executed quite often, there is the possibility of query models. A query model is a form of denormalization where relevant data for a single query is stored in a separate model. The trick of course is to keep the denormalized model in sync with the primary model. Query models can only be used if changes are entirely under your control.

models.py

class InactiveUserDistribution(models.Model):
    country = CharField(max_length=200)
    inactive_user_count = IntegerField(default=0)

The first option is to update these models in your commands. This is very useful if these models are only changed by one or two commands.

forms.py

class ActivateUserForm(forms.Form):
    # see above
   
    def execute(self):
        # see above
        query_model = InactiveUserDistribution.objects.get_or_create(country=user.country)
        query_model.inactive_user_count -= 1
        query_model.save()

A better option would be to use custom signals. These signals are of course emitted by your commands. Signals have the advantage that you can keep multiple query models in sync with your original model. Furthermore, signal processing can be offloaded to background tasks, using Celery or similar frameworks.

signals.py

user_activated = Signal(providing_args = ['user'])
user_deactivated = Signal(providing_args = ['user'])

forms.py

class ActivateUserForm(forms.Form):
    # see above
   
    def execute(self):
        # see above
        user_activated.send_robust(sender=self, user=user)

models.py

class InactiveUserDistribution(models.Model):
    # see above

@receiver(user_activated)
def on_user_activated(sender, **kwargs):
        user = kwargs['user']
        query_model = InactiveUserDistribution.objects.get_or_create(country=user.country)
        query_model.inactive_user_count -= 1
        query_model.save()
    

Keeping it clean

When using this approach, it becomes ridiculously easy to determine if your code stays clean. Just follow these guidelines:

• Does my model contain methods that do more than managing database state? You should extract a command.
• Does my model contain properties that do not map to database fields? You should extract a query.
• Does my model reference infrastructure that is not my database (such as mail)? You should extract a command.

The same goes for views (because views often suffer from the same problem).

• Does my view actively manage database models? You should extract a command.

I fixed it just by editing the gradle-wrapper.properties file.

You must go to the project folder, then /android/grandle/wrapper/gradle-wrapper.properties. In DistributionUrl, change to https \: //services.gradle.org/distributions/gradle-6.4.1-all.zip.

Code Runner Extension will only let you "run" java files.

To truly debug 'Java' files follow the quick one-time setup:

• Install Java Debugger Extension in VS Code and reload.
• open an empty folder/project in VS code.
• create your java file (s).
• create a folder .vscode in the same folder.
• create 2 files inside .vscode folder: tasks.json and launch.json
• copy paste below config in tasks.json:

{
    "version": "2.0.0",
    "type": "shell",
    "presentation": {
        "echo": true,
        "reveal": "always",
        "focus": false,
        "panel": "shared"
    },
    "isBackground": true,
    "tasks": [
        {
            "taskName": "build",
            "args": ["-g", "${file}"],
            "command": "javac"
        }
    ]
}

• copy paste below config in launch.json:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Debug Java",
            "type": "java",
            "request": "launch",
            "externalConsole": true,                //user input dosen't work if set it to false :(
            "stopOnEntry": true,
            "preLaunchTask": "build",                 // Runs the task created above before running this configuration
            "jdkPath": "${env:JAVA_HOME}/bin",        // You need to set JAVA_HOME enviroment variable
            "cwd": "${workspaceRoot}",
            "startupClass": "${workspaceRoot}${file}",
            "sourcePath": ["${workspaceRoot}"],   // Indicates where your source (.java) files are
            "classpath": ["${workspaceRoot}"],    // Indicates the location of your .class files
            "options": [],                             // Additional options to pass to the java executable
            "args": []                                // Command line arguments to pass to the startup class
        }

    ],
    "compounds": []
}

You are all set to debug java files, open any java file and press F5 (Debug->Start Debugging).

Tip: *To hide .class files in the side explorer of VS code, open settings of VS code and paste the below config:

"files.exclude": {
        "*.class": true
    }

Something like this:

.base {
    width:100px;
}

div.child {
    background-color:red;
    color:blue;
}

.child {
    background-color:yellow;
}

<div class="base child">
    hello world
</div>

The background here will be red, as the css selector is more specific, as we've said it must belong to a div element too!

Using Rendertron is an option. Under the hood, this is a headless Chrome exposing the following endpoints:

• /render/:url: Access this route e.g. with requests.get if you are interested in the DOM.
• /screenshot/:url: Access this route if you are interested in a screenshot.

You would install rendertron with npm, run rendertron in one terminal, access http://localhost:3000/screenshot/:url and save the file, but a demo is available at render-tron.appspot.com making it possible to run this Python3 snippet locally without installing the npm package:

import requests

BASE = 'https://render-tron.appspot.com/screenshot/'
url = 'https://google.com'
path = 'target.jpg'
response = requests.get(BASE + url, stream=True)
# save file, see https://stackoverflow.com/a/13137873/7665691
if response.status_code == 200:
    with open(path, 'wb') as file:
        for chunk in response:
            file.write(chunk)

You want to use postgresql's replace function:

replace(string text, from text, to text)

for instance :

UPDATE <table> SET <field> = replace(<field>, 'cat', 'dog')

Be aware, though, that this will be a string-to-string replacement, so 'category' will become 'dogegory'. the regexp_replace function may help you define a stricter match pattern for what you want to replace.

Also you can edit your Run/Debug configuration and add clean task.

Click on the Edit configuration

In the left list of available configurations choose your current configuration and then on the right side of the dialog window in the section Before launch press on plus sign and choose Run Gradle task

In the new window choose your gradle project and in the field Tasks type clean.

Then move your gradle clean on top of Gradle-Aware make

I always use the x:Name variant. I have no idea if this affects any performance, I just find it easier for the following reason. If you have your own usercontrols that reside in another assembly just the "Name" property won't always suffice. This makes it easier to just stick too the x:Name property.

You have to enable curl with php.

I have a similar question here: Writting in sub-ndarray of a ndarray in the most pythonian way. Python 2 .

Following the solution of previous post for your case the solution looks like:

columns_to_keep = [1,3] 
rows_to_keep = [1,3]

An using ix_:

x[np.ix_(rows_to_keep, columns_to_keep)] 

Which is:

array([[ 5,  7],
       [13, 15]])

Answering exactly what was asked:

hash = {"_id"=>"4de7140772f8be03da000018"}
hash.transform_keys { |key| key[1..] }
# => {"id"=>"4de7140772f8be03da000018"}

The method transform_keys exists in the Hash class since Ruby version 2.5.

I use VSPerfMon which is the StandAlone Visual Studio Profiler. I wrote a GUI tool to help me run it and look at the results.

http://code.google.com/p/vsptree/

"jdbc:mysql://localhost"

From the oracle docs..

jdbc:mysql://[host][,failoverhost...]
[:port]/[database]
[?propertyName1][=propertyValue1]
[&propertyName2][=propertyValue2]

host:port is the host name and port number of the computer hosting your database. If not specified, the default values of host and port are 127.0.0.1 and 3306, respectively.

database is the name of the database to connect to. If not specified, a connection is made with no default database.

failover is the name of a standby database (MySQL Connector/J supports failover).

propertyName=propertyValue represents an optional, ampersand-separated list of properties. These attributes enable you to instruct MySQL Connector/J to perform various tasks.

If you are running into this error while using a Docker image and that you are calling the class properly, or that the error comes from an up-to-date library, then the zip module is probably missing.

Assuming we use docker-compose, we can confirm it's missing by running docker-compose run php php -m for instance and see that zip is not listed.

To install it in your image, modify your Dockerfile so it does the same as this example.

FROM php:7.3-apache 

RUN set -eux \
    && apt-get update \
    && apt-get install -y libzip-dev zlib1g-dev \
    && docker-php-ext-install zip

Then rebuild the image with docker-compose build php and you are good to go.

If people are worried about using use strict it might be worth checking out this article:

ECMAScript 5 'Strict mode' support in browsers. What does this mean?
NovoGeek.com - Krishna's weblog

It talks about browser support, but more importantly how to deal with it safely:

function isStrictMode(){
    return !this;
} 
/*
   returns false, since 'this' refers to global object and 
   '!this' becomes false
*/

function isStrictMode(){   
    "use strict";
    return !this;
} 
/* 
   returns true, since in strict mode the keyword 'this'
   does not refer to global object, unlike traditional JS. 
   So here, 'this' is 'undefined' and '!this' becomes true.
*/

str.strip() returns a string with leading+trailing whitespace removed, .lstrip and .rstrip for only leading and trailing respectively.

grades.append(lists[i].rstrip('\n').split(','))

Clearly HttpContext.Current is not null only if you access it in a thread that handles incoming requests. That's why it works "when i use this code in another class of a page".

It won't work in the scheduling related class because relevant code is not executed on a valid thread, but a background thread, which has no HTTP context associated with.

Overall, don't use Application["Setting"] to store global stuffs, as they are not global as you discovered.

If you need to pass certain information down to business logic layer, pass as arguments to the related methods. Don't let your business logic layer access things like HttpContext or Application["Settings"], as that violates the principles of isolation and decoupling.

Update: Due to the introduction of async/await it is more often that such issues happen, so you might consider the following tip,

In general, you should only call HttpContext.Current in only a few scenarios (within an HTTP module for example). In all other cases, you should use

• Page.Context https://docs.microsoft.com/en-us/dotnet/api/system.web.ui.page.context?view=netframework-4.7.2
• Controller.HttpContext https://docs.microsoft.com/en-us/dotnet/api/system.web.mvc.controller.httpcontext?view=aspnet-mvc-5.2

instead of HttpContext.Current.

Restart your device.

In my case, the app run in most devices except for one: a cellphone that was too old and had been failing lately, the app thrown this error even without having installed the app once.

Something like this (not tested)

with match_groups as (

  select product_id, 
         matching_product_id,
         product_id as group_id
  from matches
  where product_id not in (select matching_product_id from matches)

  union all

  select m.product_id, m.matching_product_id, p.group_id
  from matches m
    join match_groups p on m.product_id = p.matching_product_id
)
select group_id, product_id
from match_groups
order by group_id;

Try putting double quotes in your filepath variable

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

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

Because I wanted conversion to plain text with LF and bullets, I found this pretty solution on codeproject, which covers many conversion usecases:

Yep, looks so big, but works fine.

You should use this one too:

./gradlew :app:dependencies (Mac and Linux) -With ./

gradlew :app:dependencies (Windows) -Without ./

The libs you are using internally using any other versions of google play service.If yes then remove or update those libs.

You can use the window.innerWidth and window.innerHeight properties.

The iPhone 4 camera is more than capabale of doing barcodes. The zebra crossing barcode library has a fork on github zxing-iphone. It's open-source.

It's simple

y = [['vegas','London'],['US','UK']]

for x in y:
    for a in x:
        print(a)

You can have better performance by using the following method:

SELECT COUNT(1) FROM (SELECT /*+FIRST_ROWS*/ column_name 
FROM table_name 
WHERE column_name = 'xxxxx' AND ROWNUM = 1);

Just go to the project Properties->Project Facets

1. Uncheck the dynamic module, click apply.

2. Maven->update the project.

You can use DataFrame.values to get an numpy array of the data and then use NumPy functions such as argsort() to get the most correlated pairs.

But if you want to do this in pandas, you can unstack and sort the DataFrame:

import pandas as pd
import numpy as np

shape = (50, 4460)

data = np.random.normal(size=shape)

data[:, 1000] += data[:, 2000]

df = pd.DataFrame(data)

c = df.corr().abs()

s = c.unstack()
so = s.sort_values(kind="quicksort")

print so[-4470:-4460]

Here is the output:

2192  1522    0.636198
1522  2192    0.636198

Another common practices is to append constantly-changing strings to the end of the requested files. For instance:

<script type="text/javascript" src="main.js?v=12392823"></script>

There are TWO approaches that you can take to use licensed web-fonts on your pages:

1. Font Hosting Services like Typekit, Fonts.com, Fontdeck, etc., provide an easy interface for designers to manage fonts purchased, and generate a link to a dynamic CSS or JavaScript file that serves up the font. Google even provides this service for free (here is an example for the Roboto font you requested). Typekit is the only service to provide additional font hinting to ensure fonts occupy the same pixels across browsers.

JS font loaders like the one used by Google and Typekit (i.e. WebFont loader) provide CSS classes and callbacks to help manage the FOUT that may occur, or response timeouts when downloading the font.

    <head>
      <!-- get the required files from 3rd party sources -->
      <link href='http://fonts.googleapis.com/css?family=Roboto' rel='stylesheet' type='text/css'>

      <!-- use the font -->
      <style>
        body {
          font-family: 'Roboto', sans-serif;
          font-size: 48px;
        }
      </style>
    </head>

2. The DIY approach involves getting a font licensed for web use, and (optionally) using a tool like FontSquirrel's generator (or some software) to optimize its file size. Then, a cross-browser implementation of the standard @font-face CSS property is used to enable the font(s).

This approach can provides better load performance since you have a more granular control over the characters to include and hence the file-size.

    /* get the required local files */
    @font-face {
      font-family: 'Roboto';
      src: url('roboto.eot'); /* IE9 Compat Modes */
      src: url('roboto.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
      url('roboto.woff') format('woff'), /* Modern Browsers */
      url('roboto.ttf')  format('truetype'), /* Safari, Android, iOS */
      url('roboto.svg#svgFontName') format('svg'); /* Legacy iOS */
    }
    
    /* use the font */
    body {
      font-family: 'Roboto', sans-serif;
      font-size: 48px;
    }

Long story short:

Using font hosting services along with @font-face declaration gives best output with respect to overall performance, compatibility and availability.

UPDATE

Roboto: Google’s signature font is now open source

You can now manually generate the Roboto fonts using instructions that can be found here.

Well one thing you could do is if you have a switch:

switch(SomeEnum)
{
  case SomeEnum.One:
      DoThings(someUser);
      break;
  case SomeEnum.Two:
      DoSomethingElse(someUser);
      break;
}

And with the might power of actions you can turn that switch into a dictionary:

Dictionary<SomeEnum, Action<User>> methodList = 
    new Dictionary<SomeEnum, Action<User>>()

methodList.Add(SomeEnum.One, DoSomething);
methodList.Add(SomeEnum.Two, DoSomethingElse); 

...

methodList[SomeEnum](someUser);

Or you could take this farther:

SomeOtherMethod(Action<User> someMethodToUse, User someUser)
{
    someMethodToUse(someUser);
}  

....

var neededMethod = methodList[SomeEnum];
SomeOtherMethod(neededMethod, someUser);

Just a couple of examples. Of course the more obvious use would be Linq extension methods.

http://www.w3.org/TR/REC-html40/struct/global.html#h-7.5.2

The id attribute assigns a unique identifier to an element (which may be verified by an SGML parser).

and

ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").

So "id" must be unique and can't contain a space.

Cracked it. Just @Damnum steps and then follow the path to run xcode. Bad way but running like a charm.

Double click to /Applications/Xcode102.app/Contents/MacOS/Xcode

I would recommend to call the script like this

...
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src="/js/my.js"></script>
</body>

The js and css files must be treat differently

Put jquery as the first before other JS scripts at the bottom of <BODY> tag

• The problem caused is that they block parallel downloads. The HTTP/1.1 specification suggests that browsers download no more than two components in parallel per hostname.
• So select 2 (two) most important scripts on your page like analytic and pixel script on the <head> tags and let the rest including the jquery to be called on the bottom <body> tag.

Put CSS style on top of <HEAD> tag after the other more priority tags

• Moving style sheets to the document HEAD makes pages appear to be loading faster. This is because putting style sheets in the HEAD allows the page to render progressively.
• So for css sheets, it is better to put them all on the <head> tag but let the style that shall be immediately rendered to be put in <style> tags inside <HEAD> and the rest in <body>.

You may also find other suggestion when you test your page like on Google PageSpeed Insight

Thanks to Mike's comment, I've re-read the doc and I've realised that my current user (i.e. userA that already has the create privilege) wasn't a direct/indirect member of the new owning role...

So the solution was quite simple - I've just done this grant:

grant userB to userA;

That's all folks ;-)

Another requirement is that the object has to be owned by user userA before altering it...

TLDR if you don't want to read all these great answers :-)

Explicit:

Using DateTimeOffset because the timezone is forced to UTC+0.

Implicit:

Using DateTime where you hope everyone sticks to the unwritten rule of the timezone always being UTC+0.

(Side note for devs: explicit is always better than implicit!)

(Side side note for Java devs, C# DateTimeOffset == Java OffsetDateTime, read this: https://www.baeldung.com/java-zoneddatetime-offsetdatetime)

Here is a generic way to loop through the field objects in an object (person):

for (var property in person) {
    console.log(property,":",person[property]);
}

The person obj looks like this:

var person={
    first_name:"johnny",
    last_name: "johnson",
    phone:"703-3424-1111"
};

Best way is

Add permission manifest file

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

Then you can get GPS location or if GPS location is not available then this function return NETWORK location

    public static Location getLocationWithCheckNetworkAndGPS(Context mContext) {
    LocationManager lm = (LocationManager)
            mContext.getSystemService(Context.LOCATION_SERVICE);
    assert lm != null;
    isGpsEnabled = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
    isNetworkLocationEnabled = lm.isProviderEnabled(LocationManager.NETWORK_PROVIDER);

    Location networkLoacation = null, gpsLocation = null, finalLoc = null;
    if (isGpsEnabled)
        if (ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(mContext, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

            return null;
        }gpsLocation = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER);
    if (isNetworkLocationEnabled)
        networkLoacation = lm.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);

    if (gpsLocation != null && networkLoacation != null) {

        //smaller the number more accurate result will
        if (gpsLocation.getAccuracy() > networkLoacation.getAccuracy())
            return finalLoc = networkLoacation;
        else
            return finalLoc = gpsLocation;

    } else {

        if (gpsLocation != null) {
            return finalLoc = gpsLocation;
        } else if (networkLoacation != null) {
            return finalLoc = networkLoacation;
        }
    }
    return finalLoc;
}

Below is an example of the correct way I think. At least it is what I use. You need to do Response.Clear to get rid of any headers that are already populated. You need to pass the correct ContentType of text/xml. That is the way you serve xml. In general you want to serve it as charset UTF-8 as that is what most parsers are expecting. But I don't think it has to be that. But if you change it make sure to change your xml document declaration and indicate the charset in there. You need to use the XmlWriter so you can actually write in UTF-8 and not whatever charset is the default. And to have it properly encode your xml data in UTF-8.

onNewIntent() is meant as entry point for singleTop activities which already run somewhere else in the stack and therefore can't call onCreate(). From activities lifecycle point of view it's therefore needed to call onPause() before onNewIntent(). I suggest you to rewrite your activity to not use these listeners inside of onNewIntent(). For example most of the time my onNewIntent() methods simply looks like this:

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    // getIntent() should always return the most recent
    setIntent(intent);
}

With all setup logic happening in onResume() by utilizing getIntent().

.html(''). was the only method that solved it for me.

Well, I don't know about JavaScript, it should really be just a matter of re-evaluation array length and maybe something to do with the associative arrays (if you only decrement, it is unlikely new entries would need to be allocated - if the array is dense, that is. someone may optimize for that).

In low-level assembly, there is a looping instruction, called DJNZ (decrement and jump if non-zero). So the decrement and jump is all in one instruction, making it possibly ever-so-slightly faster than INC and JL / JB (increment, jump if less than / jump if below). Also, comparing against zero is simpler than comparing against another number. But all that is really marginal and also depends on target architecture (could make difference e.g. on Arm in a smartphone).

I wouldn't expect this low-level differences to have so great impact on interpreted languages, I just haven't seen DJNZ among the responses so I thought I would share an interesting thought.

You could make it through iframes... I made something, but my only problem for now is syncing those divs to scroll simultaneous... its terrible way, because its like you load 2 websites, but the only way I found... you could also work with divs and overflow I guess...

Dont know is it related to your problem or not BUT Windows 2008 Server R2 or SP2 has changed its IIS settings, which leads to issue in session persistence. By default, it manages separate session variable for HTTP and HTTPS. When variables are set in HTTPS, these will be available only on HTTPS pages whenever switched.

To solve the issue, there is IIS setting. In IIS Manager, open up the ASP properties, expand Session Properties, and change New ID On Secure Connection to False.

For me, the problem was only on certain (long) links within the website and was tracked down to URLScan having the default configuration of a URL length limit of 260.

Use the same process. You already have the variable iDiv which still refers to the original element <div id='block'> you've created. You just need to create another <div> and call appendChild().

// Your existing code unmodified...
var iDiv = document.createElement('div');
iDiv.id = 'block';
iDiv.className = 'block';
document.getElementsByTagName('body')[0].appendChild(iDiv);

// Now create and append to iDiv
var innerDiv = document.createElement('div');
innerDiv.className = 'block-2';

// The variable iDiv is still good... Just append to it.
iDiv.appendChild(innerDiv);

The order of event creation doesn't have to be as I have it above. You can alternately append the new innerDiv to the outer div before you add both to the <body>.

var iDiv = document.createElement('div');
iDiv.id = 'block';
iDiv.className = 'block';

// Create the inner div before appending to the body
var innerDiv = document.createElement('div');
innerDiv.className = 'block-2';

// The variable iDiv is still good... Just append to it.
iDiv.appendChild(innerDiv);

// Then append the whole thing onto the body
document.getElementsByTagName('body')[0].appendChild(iDiv);

INSERT INTO test VALUES('a line\nanother line');

\n just works fine here

you could utilize bootstrap events:: as

//when modal opens
$('#yourModal').on('shown.bs.modal', function (e) {
  $("#pageContent").css({ opacity: 0.5 });
})

//when modal closes
$('#yourModal').on('hidden.bs.modal', function (e) {
  $("#pageContent").css({ opacity: 1 });
})

I had same issues, edited my hosts file 127.0.0.1 localhost, but noticed no difference.

I then disabled Compression in the IIS panel and applied, and problem appears to now be resolved.

IIS Manager > Compression > Uncheck 'Enable dynamic content compression' and uncheck 'Enable static content compression'. Then 'Apply'.

Hope this helps!

Allow only Alphabets in EditText android:

InputFilter letterFilter = new InputFilter() {
        public CharSequence filter(CharSequence source, int start, int end, Spanned dest, int dstart, int dend) {
            String filtered = "";
            for (int i = start; i < end; i++) {
                char character = source.charAt(i);
                if (!Character.isWhitespace(character)&&Character.isLetter(character)) {
                    filtered += character;
                }
            }

            return filtered;
        }

    };
editText.setFilters(new InputFilter[]{letterFilter}); 

In SQL Server 2012, 2014:

USE mydb
GO

ALTER ROLE db_datareader ADD MEMBER MYUSER
GO
ALTER ROLE db_datawriter ADD MEMBER MYUSER
GO

In SQL Server 2008:

use mydb
go

exec sp_addrolemember db_datareader, MYUSER 
go
exec sp_addrolemember db_datawriter, MYUSER 
go

To also assign the ability to execute all Stored Procedures for a Database:

GRANT EXECUTE TO MYUSER;

To assign the ability to execute specific stored procedures:

GRANT EXECUTE ON dbo.sp_mystoredprocedure TO MYUSER;

Since I have to reuse this few time, I came up with this class that simply help to abstract how the query string is composed.

public class UriBuilderExt
{
    private NameValueCollection collection;
    private UriBuilder builder;

    public UriBuilderExt(string uri)
    {
        builder = new UriBuilder(uri);
        collection = System.Web.HttpUtility.ParseQueryString(string.Empty);
    }

    public void AddParameter(string key, string value) {
        collection.Add(key, value);
    }

    public Uri Uri{
        get
        {
            builder.Query = collection.ToString();
            return builder.Uri;
        }
    }

}

The use will be simplify to something like this:

var builder = new UriBuilderExt("http://example.com/");
builder.AddParameter("foo", "bar<>&-baz");
builder.AddParameter("bar", "second");
var uri = builder.Uri;

that will return the uri: http://example.com/?foo=bar%3c%3e%26-baz&bar=second

First of all, remove component folder, which you have to delete and then remove its entries which you have made in "ts" files.
