window_handles should give you the references to all open windows.

this is what the docu has to say about switching windows.

Move script tag at the end of BODY instead of HEAD because in current code when the script is computed html element doesn't exist in document.

Since you don't want to you jquery. Use window.onload or document.onload to execute the entire piece of code that you have in current script tag. window.onload vs document.onload

If you are using a UNIX system, you could do

git log|grep "Author"|wc -l

table
{
  table-layout:fixed;
}
td,th
{
  width:20px; 
  word-wrap:break-word;
}

:first-child ... :nth-child(1) or ...

thread will be killed when it finish it's work, so if you are using loops or something else you should pass variable to the thread to stop the loop after that the thread will be finished.

You can write a custom validation attribute:

[AttributeUsage(AttributeTargets.Property | AttributeTargets.Field | AttributeTargets.Parameter, AllowMultiple = false)]
public class Numeric : ValidationAttribute
{
    public Numeric(string errorMessage) : base(errorMessage)
    {
    }

    /// <summary>
    /// Check if given value is numeric
    /// </summary>
    /// <param name="value">The input value</param>
    /// <returns>True if value is numeric</returns>
    public override bool IsValid(object value)
    {
        return decimal.TryParse(value?.ToString(), out _);
    }
}

On your property you can then use the following annotation:

[Numeric("Please fill in a valid number.")]
public int NumberOfBooks { get; set; }

Open the file for 'append' rather than 'write'.

with open('file.txt', 'a') as file:
    file.write('input')

Clearfix from bootstrap:

.clearfix:after {
  clear: both;
}

getFragmentManager() has been deprecated in favor of getParentFragmentManager() to make it clear that you want to access the fragment manager of the parent instead of any child fragments.

Simply use getParentFragmentManager() in Java or parentFragmentManager in Kotlin.

The way I like to do this is to convert both the original set and the values I'd like to add into lists, add them, and then convert them back into a set, like this:

setMenu = {"Eggs", "Bacon"}
print(setMenu)
> {'Bacon', 'Eggs'}
setMenu = set(list(setMenu) + list({"Spam"}))
print(setMenu)
> {'Bacon', 'Spam', 'Eggs'}
setAdditions = {"Lobster", "Sausage"}
setMenu = set(list(setMenu) + list(setAdditions))
print(setMenu)
> {'Lobster', 'Spam', 'Eggs', 'Sausage', 'Bacon'}

This way I can also easily add multiple sets using the same logic, which gets me an TypeError: unhashable type: 'set' if I try doing it with the .update() method.

I had this error when going from version 10.0.0.0, i.e. "Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" />

to version 11.0.0.0, i.e.

"Microsoft.ReportViewer.WebForms, Version=11.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91"

It took a while until I understood that not only the version was changed but also the public token key, as you can see above.

Yeah it's possible.

Button myBtn = (Button)findViewById(R.id.myButtonId);
myBtn.requestFocus();

or in XML

<Button ...><requestFocus /></Button>

Important Note: The button widget needs to be focusable and focusableInTouchMode. Most widgets are focusable but not focusableInTouchMode by default. So make sure to either set it in code

myBtn.setFocusableInTouchMode(true);

or in XML

android:focusableInTouchMode="true"

Probably because it just didn't make much sense for list semantics. However, you can easily create your own by subclassing.

class safelist(list):
    def get(self, index, default=None):
        try:
            return self.__getitem__(index)
        except IndexError:
            return default

def _test():
    l = safelist(range(10))
    print l.get(20, "oops")

if __name__ == "__main__":
    _test()

Below is the code using lambdas

#include "stdafx.h"
#include <vector>
#include <algorithm>

using namespace std;

struct MyStruct
{
    int key;
    std::string stringValue;

    MyStruct(int k, const std::string& s) : key(k), stringValue(s) {}
};

int main()
{
    std::vector < MyStruct > vec;

    vec.push_back(MyStruct(4, "test"));
    vec.push_back(MyStruct(3, "a"));
    vec.push_back(MyStruct(2, "is"));
    vec.push_back(MyStruct(1, "this"));

    std::sort(vec.begin(), vec.end(), 
        [] (const MyStruct& struct1, const MyStruct& struct2)
        {
            return (struct1.key < struct2.key);
        }
    );
    return 0;
}

so it's easy)))

Watch this...

    var stuff = {};
    $('input[type=checkbox]').each(function(i, e) {
        stuff[i] = e.checked;
    });

And you will have:

Object {0: true, 1: false, 2: false, 3: false}

Or:

$('input[type=checkbox]').each(function(i, e) {
    stuff['row'+i] = e.checked;
});

You will have:

Object {row0: true, row1: false, row2: false, row3: false}

Or:

$('input[type=checkbox]').each(function(i, e) {
    stuff[e.className+i] = e.checked;
});

You will have:

Object {checkbox0: true, checkbox1: false, checkbox2: false, checkbox3: false}

If you want to change to particular folder in the drive:

cd D:\Newfolder

You are writing if(true) so it will always show "Hello " message.

You should take decision on the basis of value of n returned.

For people who find this via search engines, you do not need VBA. You can just:

1.) select the query or table with your mouse
2.) click export data from the ribbon
3.) click excel from the export subgroup
4.) follow the wizard to select the output file and location.

1. Generally system/global config is stored somewhere under /etc.
2. User-specific config is stored in the user's home directory, often as a hidden file, sometimes as a hidden directory containing non-hidden files (and possibly more subdirectories).

Generally speaking, command line options will override environment variables which will override user defaults which will override system defaults.

Check out the pack URI syntax. You want something like this:

dataGridView1.Columns is probably of a length less than 5. Accessing dataGridView1.Columns[4] then will be outside the list.

Base64 encoding is not meant to provide security

Base64 encoding is not meant to compress data

Why do we use Base64

Base64 is a text representation of data that consists of only 64 characters which are the alphanumeric characters (lowercase and uppercase), +, / and =. These 64 characters are considered ‘safe’, that is, they can not be misinterpreted by legacy computers and programs unlike characters such as <, > \n and many others.

Go to your Microsoft SDKs directory. A path like this:

C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6 Tools

Open the WCF Configuration Editor (Microsoft Service Configuration Editor) from that directory:

SvcConfigEditor.exe

(another option to open this tool is by navigating in Visual Studio 2017 to "Tools" > "WCF Service Configuration Editor")

Open your .config file or create a new one using the editor and navigate to Diagnostics.

There you can click the "Enable MessageLogging".

It's not possible to define member functions or derive structs from each other in C.

Also, C++ is not only C + "derive structs". Templates, references, user defined namespaces and operator overloading all do not exist in C.

Have a look at Pig Vs Hive Comparison in a nut shell from a "dezyre" article

Hive is better than PIG in: Partitions, Server, Web interface & JDBC/ODBC support.

Some differences:

1. Hive is best for structured Data & PIG is best for semi structured data

2. Hive is used for reporting & PIG for programming

3. Hive is used as a declarative SQL & PIG as a procedural language

4. Hive supports partitions & PIG does not

5. Hive can start an optional thrift based server & PIG cannot

6. Hive defines tables beforehand (schema) + stores schema information in a database & PIG doesn't have a dedicated metadata of database

7. Hive does not support Avro but PIG does. EDIT: Hive supports Avro, specify the serde as org.apache.hadoop.hive.serde2.avro

8. Pig also supports additional COGROUP feature for performing outer joins but hive does not. But both Hive & PIG can join, order & sort dynamically.

If you write your code in emacs then you might be interested in the htmlize elisp package.

Check out this link it has a example code to encrypt/decrypt data using AES256CBC using EVP API.

https://github.com/saju/misc/blob/master/misc/openssl_aes.c

Also you can check the use of AES256 CBC in a detailed open source project developed by me at https://github.com/llubu/mpro

The code is detailed enough with comments and if you still need much explanation about the API itself i suggest check out this book Network Security with OpenSSL by Viega/Messier/Chandra (google it you will easily find a pdf of this..) read chapter 6 which is specific to symmetric ciphers using EVP API.. This helped me a lot actually understanding the reasons behind using various functions and structures of EVP.

and if you want to dive deep into the Openssl crypto library, i suggest download the code from the openssl website (the version installed on your machine) and then look in the implementation of EVP and aeh api implementation.

One more suggestion from the code you posted above i see you are using the api from aes.h instead use EVP. Check out the reason for doing this here OpenSSL using EVP vs. algorithm API for symmetric crypto nicely explained by Daniel in one of the question asked by me..

Yes, a foreign key can be a primary key in the case of one to one relationship between those tables

I have always found Exceptions are much slower to be handled.

Perhaps a less intensive way would yeild a better, faster, result?

public bool IsValidUri(Uri uri)
{

    using (HttpClient Client = new HttpClient())
    {

    HttpResponseMessage result = Client.GetAsync(uri).Result;
    HttpStatusCode StatusCode = result.StatusCode;

    switch (StatusCode)
    {

        case HttpStatusCode.Accepted:
            return true;
        case HttpStatusCode.OK:
            return true;
         default:
            return false;
        }
    }
}

Then just use:

IsValidUri(new Uri("http://www.google.com/censorship_algorithm"));

TL;DR:

socket.send(data, callback) is essentially equivalent to calling socket.emit('message', JSON.stringify(data), callback)

Without looking at the source code, I would assume that the send function is more efficient edit: for sending string messages, at least?

So yeah basically emit allows you to send objects, which is very handy.

Take this example with socket.emit:

sendMessage: function(type, message) {
    socket.emit('message', {
        type: type,
        message: message
    });
}

and for those keeping score at home, here is what it looks like using socket.send:

sendMessage: function(type, message) {
    socket.send(JSON.stringify({
        type: type,
        message: message
    }));
}

Add the active: false option (documentation)..

$("#accordion").accordion({ header: "h3", collapsible: true, active: false });

A lot of other answers are focusing on a pattern that does work, but their explanations aren't really very thorough as to why your current code doesn't work.

Your code, for reference:

function funcName() {
    alert("test");
}

var func = funcName();
var run = setInterval("func",10000)

Let's break this up into chunks. Your function funcName is fine. Note that when you call funcName (in other words, you run it) you will be alerting "test". But notice that funcName() -- the parentheses mean to "call" or "run" the function -- doesn't actually return a value. When a function doesn't have a return value, it defaults to a value known as undefined.

When you call a function, you append its argument list to the end in parentheses. When you don't have any arguments to pass the function, you just add empty parentheses, like funcName(). But when you want to refer to the function itself, and not call it, you don't need the parentheses because the parentheses indicate to run it.

So, when you say:

var func = funcName();

You are actually declaring a variable func that has a value of funcName(). But notice the parentheses. funcName() is actually the return value of funcName. As I said above, since funcName doesn't actually return any value, it defaults to undefined. So, in other words, your variable func actually will have the value undefined.

Then you have this line:

var run = setInterval("func",10000)

The function setInterval takes two arguments. The first is the function to be ran every so often, and the second is the number of milliseconds between each time the function is ran.

However, the first argument really should be a function, not a string. If it is a string, then the JavaScript engine will use eval on that string instead. So, in other words, your setInterval is running the following JavaScript code:

func
// 10 seconds later....
func
// and so on

However, func is just a variable (with the value undefined, but that's sort of irrelevant). So every ten seconds, the JS engine evaluates the variable func and returns undefined. But this doesn't really do anything. I mean, it technically is being evaluated every 10 seconds, but you're not going to see any effects from that.

The solution is to give setInterval a function to run instead of a string. So, in this case:

var run = setInterval(funcName, 10000);

Notice that I didn't give it func. This is because func is not a function in your code; it's the value undefined, because you assigned it funcName(). Like I said above, funcName() will call the function funcName and return the return value of the function. Since funcName doesn't return anything, this defaults to undefined. I know I've said that several times now, but it really is a very important concept: when you see funcName(), you should think "the return value of funcName". When you want to refer to a function itself, like a separate entity, you should leave off the parentheses so you don't call it: funcName.

So, another solution for your code would be:

var func = funcName;
var run = setInterval(func, 10000);

However, that's a bit redundant: why use func instead of funcName?

Or you can stay as true as possible to the original code by modifying two bits:

var func = funcName;
var run = setInterval("func()", 10000);

In this case, the JS engine will evaluate func() every ten seconds. In other words, it will alert "test" every ten seconds. However, as the famous phrase goes, eval is evil, so you should try to avoid it whenever possible.

Another twist on this code is to use an anonymous function. In other words, a function that doesn't have a name -- you just drop it in the code because you don't care what it's called.

setInterval(function () {
    alert("test");
}, 10000);

In this case, since I don't care what the function is called, I just leave a generic, unnamed (anonymous) function there.

As Cubbi pointed out in one of the comments, std::wstring_convert (C++11) provides a neat simple solution (you need to #include <locale> and <codecvt>):

std::wstring string_to_convert;

//setup converter
using convert_type = std::codecvt_utf8<wchar_t>;
std::wstring_convert<convert_type, wchar_t> converter;

//use converter (.to_bytes: wstr->str, .from_bytes: str->wstr)
std::string converted_str = converter.to_bytes( string_to_convert );

I was using a combination of wcstombs and tedious allocation/deallocation of memory before I came across this.

http://en.cppreference.com/w/cpp/locale/wstring_convert

update(2013.11.28)

One liners can be stated as so (Thank you Guss for your comment):

std::wstring str = std::wstring_convert<std::codecvt_utf8<wchar_t>>().from_bytes("some string");

Wrapper functions can be stated as so: (Thank you ArmanSchwarz for your comment)

std::wstring s2ws(const std::string& str)
{
    using convert_typeX = std::codecvt_utf8<wchar_t>;
    std::wstring_convert<convert_typeX, wchar_t> converterX;

    return converterX.from_bytes(str);
}

std::string ws2s(const std::wstring& wstr)
{
    using convert_typeX = std::codecvt_utf8<wchar_t>;
    std::wstring_convert<convert_typeX, wchar_t> converterX;

    return converterX.to_bytes(wstr);
}

Note: there's some controversy on whether string/wstring should be passed in to functions as references or as literals (due to C++11 and compiler updates). I'll leave the decision to the person implementing, but it's worth knowing.

Note: I'm using std::codecvt_utf8 in the above code, but if you're not using UTF-8 you'll need to change that to the appropriate encoding you're using:

http://en.cppreference.com/w/cpp/header/codecvt

See http://www.w3.org/TR/html401/interact/forms.html#h-17.9 for the W3 recommendations.

They say it can be done either way. They describe the two methods as explicit (using "for" with the element's id) and implicit (embedding the element in the label):

Explicit:

The for attribute associates a label with another control explicitly: the value of the for attribute must be the same as the value of the id attribute of the associated control element.

Implicit:

To associate a label with another control implicitly, the control element must be within the contents of the LABEL element. In this case, the LABEL may only contain one control element.

Try the following code

Month = Date = DateTime.Now.Month.ToString();   
Year = DateTime.Now.Year.ToString(); 
ViewBag.Today = System.Globalization.CultureInfo.InvariantCulture.DateTimeFormat.GetMonthName(Int32.Parse(Month)) + Year;

//    UITableViewCell set Identify "Cell"
//    UITableView Name is  tableReport

UIViewController,UITableViewDelegate,UITableViewDataSource,UINavigationControllerDelegate, UIImagePickerControllerDelegate {

    @IBOutlet weak var tableReport: UITableView!  

    func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
            return 5;
        }

        func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
            let cell = tableReport.dequeueReusableCell(withIdentifier: "Cell", for: indexPath)
            cell.textLabel?.text = "Report Name"
            return cell;
        }
}

IFS The Internal Field Separator that is used for word splitting after expansion and to split lines into words with the read builtin command. The default value is ``''.

IFS is a shell environment variable so it will remain unchanged within the context of your Shell script but not otherwise, unless you EXPORT it. ALSO BE AWARE, that IFS will not likely be inherited from your Environment at all: see this gnu post for the reasons and more info on IFS.

You're code written like this:

IFS=","
for word in $(cat tmptest | sed -n 1'p' | tr ',' '\n'); do echo $word; done;

should work, I tested it on command line.

As mentioned already, the contents are stored at the server. However the session is identified by a session-id, which is stored at the client and send with each request. Usually the session-id is stored in a cookie, but it can also be appended to urls. (That's the PHPSESSID query-parameter you some times see)

If you want search for printable strings, you can use:

strings will output all printable strings from a binary with offsets, and grep will search within.

            DateTime.Now);
        File.WriteAllText(n, "abc");
    }
}

Output :

C:\Users\Fez\Documents\text-2020-01-08_05-23-13-PM.bin

"text-{0:yyyy-MM-dd_hh-mm-ss-tt}.bin"

text- The first part of the output required Files will all start with text-

{0: Indicates that this is a string placeholder The zero indicates the index of the parameters inserted here

yyyy- Prints the year in four digits followed by a dash This has a "year 10000" problem

MM- Prints the month in two digits

dd_ Prints the day in two digits followed by an underscore

hh- Prints the hour in two digits

mm- Prints the minute, also in two digits

ss- As expected, it prints the seconds

tt Prints AM or PM depending on the time of day

To expand on the Wikipedia-based answers:

The Social Security Administration (SSA) explicitly states in this document that the having "000" in the first group of numbers "will NEVER be a valid SSN":

• http://www.socialsecurity.gov/employer/stateweb.htm

I'd consider that pretty definitive.

However, that the 2nd or 3rd groups of numbers won't be "00" or "0000" can be inferred from a FAQ that the SSA publishes which indicates that allocation of those groups starts at "01" or "0001":

• http://ssa-custhelp.ssa.gov/cgi-bin/ssa.cfg/php/enduser/std_adp.php?p_faqid=87

But this is only a FAQ and it's never outright stated that "00" or "0000" will never be used.

In another FAQ they provide (http://www.socialsecurity.gov/employer/randomizationfaqs.html#a0=6) that "00" or "0000" will never be used.

I can't find a reference to the 'advertisement' reserved SSNs on the SSA site, but it appears that no numbers starting with a 3 digit number higher than 772 (according to the document referenced above) have been assigned yet, but there's nothing I could find that states those numbers are reserved. Wikipedia's reference is a book that I don't have access to. The Wikipedia information on the advertisement reserved numbers is mentioned across the web, but many are clearly copied from Wikipedia. I think it would be nice to have a citation from the SSA, though I suspect that now that Wikipedia has made the idea popular that these number would now have to be reserved for advertisements even if they weren't initially.

The SSA has a page with a couple of stories about SSN's they've had to retire because they were used in advertisements/samples (maybe the SSA should post a link to whatever their current policy on this might be):

• http://www.ssa.gov/history/ssn/misused.html

For .NET Core 2.2 you can publish the application and set the target to be a self-contained executable.

In Visual Studio right click your console application project. Select publish to folder and set the profile settings like so:

You'll find your compiled code with the .exe in the publish folder.

Just spicing up the shell script above to delete older files but with logging and calculation of elapsed time

#!/bin/bash

path="/data/backuplog/"
timestamp=$(date +%Y%m%d_%H%M%S)    
filename=log_$timestamp.txt    
log=$path$filename
days=7

START_TIME=$(date +%s)

find $path -maxdepth 1 -name "*.txt"  -type f -mtime +$days  -print -delete >> $log

echo "Backup:: Script Start -- $(date +%Y%m%d_%H%M)" >> $log


... code for backup ...or any other operation .... >> $log


END_TIME=$(date +%s)

ELAPSED_TIME=$(( $END_TIME - $START_TIME ))


echo "Backup :: Script End -- $(date +%Y%m%d_%H%M)" >> $log
echo "Elapsed Time ::  $(date -d 00:00:$ELAPSED_TIME +%Hh:%Mm:%Ss) "  >> $log

The code adds a few things.

• log files named with a timestamp
• log folder specified
• find looks for *.txt files only in the log folder
• type f ensures you only deletes files
• maxdepth 1 ensures you dont enter subfolders
• log files older than 7 days are deleted ( assuming this is for a backup log)
• notes the start / end time
• calculates the elapsed time for the backup operation...

Note: to test the code, just use -print instead of -print -delete. But do check your path carefully though.

Note: Do ensure your server time is set correctly via date - setup timezone/ntp correctly . Additionally check file times with 'stat filename'

Note: mtime can be replaced with mmin for better control as mtime discards all fractions (older than 2 days (+2 days) actually means 3 days ) when it deals with getting the timestamps of files in the context of days

-mtime +$days  --->  -mmin  +$((60*24*$days))

Create a new AVD with the AVD Manager and set the Target to API Level 7. Try running your application with that AVD. Additionally, make sure that your min sdk in your Manifest file is at least set to 7.

Here's another instance similar to the examples above that you may only have one config file define where CORS is: There were two web.config files on the IIS server on the path in different directories, and one of them was hidden in the virtual directory. To solve it I deleted the root level config file since the path was using the config file in the virtual directory. Have to choose one or the other.

URL called:  'https://example.com/foo/bar'
                     ^              ^
      CORS config file in root      virtual directory with another CORS config file
          deleted this config             other sites using this

In code, you need to explicitly create a Brush instance:

Fill = new SolidColorBrush(Color.FromArgb(0xff, 0xff, 0x90))

Have a look at building a simple directory browser using php RecursiveDirectoryIterator

Also, as you mentioned you want to list you can also look at some ready made libraries that create file/folder explorers e.g.:

To change color for options menu items you can

override fun onCreateOptionsMenu(menu: Menu?): Boolean {
    menuInflater.inflate(R.menu.your_menu, menu)

    menu?.forEach {
        it.icon.setTint(Color.your_color)
    }

    return true
}

{ echo $password; echo $password; } | passwd $username 

Adding to @Martin's answer...

If anyone planning to keep an application level constant file, you can group the constant based on their type or nature

struct Constants {
    struct MixpanelConstants {
        static let activeScreen = "Active Screen";
    }
    struct CrashlyticsConstants {
        static let userType = "User Type";
    }
}

Call : Constants.MixpanelConstants.activeScreen

UPDATE 5/5/2019 (kinda off topic but ???)

After reading some code guidelines & from personal experiences it seems structs are not the best approach for storing global constants for a couple of reasons. Especially the above code doesn't prevent initialization of the struct. We can achieve it by adding some boilerplate code but there is a better approach

ENUMS

The same can be achieved using an enum with a more secure & clear representation

enum Constants {
    enum MixpanelConstants: String {
        case activeScreen = "Active Screen";
    }
    enum CrashlyticsConstants: String {
        case userType = "User Type";
    }
}

print(Constants.MixpanelConstants.activeScreen.rawValue)

There are general two ways to do this:

Print without newline in Python 3.x

Append nothing after the print statement and remove '\n' by using end='' as:

>>> print('hello')
hello  # appending '\n' automatically
>>> print('world')
world # with previous '\n' world comes down

# solution is:
>>> print('hello', end='');print(' world'); # end with anything like end='-' or end=" " but not '\n'
hello world # it seem correct output

Another Example in Loop:

for i in range(1,10):
    print(i, end='.')

Print without newline in Python 2.x

Adding a trailing comma says that after print ignore \n.

>>> print "hello",; print" world"
hello world

Another Example in Loop:

for i in range(1,10):
    print "{} .".format(i),

There are various alternative answers at this previous question - which admittedly was targeting an integer array as the source, but received generalised answers.

Had same issue, however I'm using Macbook Pro (2016) which has USB-c only and I forgot my adapter at home.

Since unable to run adb at all on my development machine, I found a different approach.

Connecting phone with USB cable to another computer (in same WiFi) and enable run adb tcpip from there.

Master-machine : computer where development goes on, with only USB-C connectors

Slave-machine: another computer with USB and in same WiFi

Steps:

1. Connect the phone to a different computer (slave-machine)
2. Run adb usb && adb tcpip 5555 from there

3. On master machine

   deko$: adb devices
   List of devices attached
   
   deko$: adb connect 10.0.20.153:5555
   connected to 10.0.20.153:5555
   

4. Now Android Studio or Xamarin can install and run app on the phone

Sidenote:

I also tested Bluetooth tethering from the Phone to Master-machine and successfully connected to phone. Both Android Studio and Xamarin worked well, however the upload process, from Xamarin was taking long time. But it works.

I had the same problem. The only thing that solved it was merge the content of META-INF/spring.handler and META-INF/spring.schemas of each spring jar file into same file names under my META-INF project.

This two threads explain it better:

• maven assembly plugin and spring namespace handlers
• Thread: unable to locate Spring NamespaceHandler for XML schema namespace

These messages are due to incorrect default value of core.autocrlf on Windows.

The concept of autocrlf is to handle line endings conversions transparently. And it does!

Bad news: value needs to be configured manually.
Good news: it should only be done ONE time per git installation (per project setting is also possible).

How autocrlf works:

core.autocrlf=true:      core.autocrlf=input:     core.autocrlf=false:
                                             
        repo                     repo                     repo
      ^      V                 ^      V                 ^      V
     /        \               /        \               /        \
crlf->lf    lf->crlf     crlf->lf       \             /          \      
   /            \           /            \           /            \

Here crlf = win-style end-of-line marker, lf = unix-style (and mac osx).

(pre-osx cr in not affected for any of three options above)

When does this warning show up (under Windows)

    – autocrlf = true if you have unix-style lf in one of your files (= RARELY),
    – autocrlf = input if you have win-style crlf in one of your files (= almost ALWAYS),
    – autocrlf = false – NEVER!

What does this warning mean

The warning "LF will be replaced by CRLF" says that you (having autocrlf=true) will lose your unix-style LF after commit-checkout cycle (it will be replaced by windows-style CRLF). Git doesn't expect you to use unix-style LF under windows.

The warning "CRLF will be replaced by LF" says that you (having autocrlf=input) will lose your windows-style CRLF after a commit-checkout cycle (it will be replaced by unix-style LF). Don't use input under windows.

Yet another way to show how autocrlf works

1) true:             x -> LF -> CRLF
2) input:            x -> LF -> LF
3) false:            x -> x -> x

where x is either CRLF (windows-style) or LF (unix-style) and arrows stand for

file to commit -> repository -> checked out file

How to fix

Default value for core.autocrlf is selected during git installation and stored in system-wide gitconfig (%ProgramFiles(x86)%\git\etc\gitconfig). Also there're (cascading in the following order):

   – "global" (per-user) gitconfig located at ~/.gitconfig, yet another
   – "global" (per-user) gitconfig at $XDG_CONFIG_HOME/git/config or $HOME/.config/git/config and
   – "local" (per-repo) gitconfig at .git/config in the working dir.

So, write git config core.autocrlf in the working dir to check the currently used value and

   – add autocrlf=false to system-wide gitconfig         # per-system solution
   – git config --global core.autocrlf false            # per-user solution
   – git config --local core.autocrlf false              # per-project solution

Warnings
– git config settings can be overridden by gitattributes settings.
– crlf -> lf conversion only happens when adding new files, crlf files already existing in the repo aren't affected.

Moral (for Windows):
    - use core.autocrlf = true if you plan to use this project under Unix as well (and unwilling to configure your editor/IDE to use unix line endings),
    - use core.autocrlf = false if you plan to use this project under Windows only (or you have configured your editor/IDE to use unix line endings),
    - never use core.autocrlf = input unless you have a good reason to (eg if you're using unix utilities under windows or if you run into makefiles issues),

PS What to choose when installing git for Windows?
If you're not going to use any of your projects under Unix, don't agree with the default first option. Choose the third one (Checkout as-is, commit as-is). You won't see this message. Ever.

PPS My personal preference is configuring the editor/IDE to use Unix-style endings, and setting core.autocrlf to false.

For me, it was an inconsistency between Debug profile (it was automatic) and Release profile (it was manual). Setting them both automatic/manual resolved the issue.

What you want to do is separate the content of the table from the header of the table. You want only the <th> elements to be scrolled. You can easily define this separation in HTML with the <tbody> and the <thead> elements.
Now the header and the body of the table are still connected to each other, they will still have the same width (and same scroll properties). Now to let them not 'work' as a table anymore you can set the display: block. This way <thead> and <tbody> are separated.

table tbody, table thead
{
    display: block;
}

Now you can set the scroll to the body of the table:

table tbody 
{
   overflow: auto;
   height: 100px;
}

And last, because the <thead> doesn't share the same width as the body anymore, you should set a static width to the header of the table:

th
{
    width: 72px;
}

You should also set a static width for <td>. This solves the issue of the unaligned columns.

td
{
    width: 72px;
}

<tr>
     <th>head1</th>
     <th>head2</th>
     <th>head3</th>
     <th>head4</th>
</tr>

I hope this is what you meant.

jsFiddle

Addendum

If you would like to have more control over the column widths, have them to vary in width between each other, and course keep the header and body columns aligned, you can use the following example:

    table th:nth-child(1), td:nth-child(1) { min-width: 50px;  max-width: 50px; }
    table th:nth-child(2), td:nth-child(2) { min-width: 100px; max-width: 100px; }
    table th:nth-child(3), td:nth-child(3) { min-width: 150px; max-width: 150px; }
    table th:nth-child(4), td:nth-child(4) { min-width: 200px; max-width: 200px; }

This code works to catch the user closing the console window:

using System;
using System.Runtime.InteropServices;

class Program {
    static void Main(string[] args) {
        handler = new ConsoleEventDelegate(ConsoleEventCallback);
        SetConsoleCtrlHandler(handler, true);
        Console.ReadLine();
    }

    static bool ConsoleEventCallback(int eventType) {
        if (eventType == 2) {
            Console.WriteLine("Console window closing, death imminent");
        }
        return false;
    }
    static ConsoleEventDelegate handler;   // Keeps it from getting garbage collected
    // Pinvoke
    private delegate bool ConsoleEventDelegate(int eventType);
    [DllImport("kernel32.dll", SetLastError = true)]
    private static extern bool SetConsoleCtrlHandler(ConsoleEventDelegate callback, bool add);

}

Beware of the restrictions. You have to respond quickly to this notification, you've got 5 seconds to complete the task. Take longer and Windows will kill your code unceremoniously. And your method is called asynchronously on a worker thread, the state of the program is entirely unpredictable so locking is likely to be required. Do make absolutely sure that an abort cannot cause trouble. For example, when saving state into a file, do make sure you save to a temporary file first and use File.Replace().

Sort of:

class some_class {
    static std::vector<std::string> v; // declaration
};

const char *vinit[] = {"one", "two", "three"};

std::vector<std::string> some_class::v(vinit, end(vinit)); // definition

end is just so I don't have to write vinit+3 and keep it up to date if the length changes later. Define it as:

template<typename T, size_t N>
T * end(T (&ra)[N]) {
    return ra + N;
}

You need to have your variables exported. So for example in Linux:

export EnvironmentVariableName=foo

Unexported variables are empty in CMAKE.

If that really is all that's in your CSS file, then yes, nothing will happen. You need a selector, even if it's as simple as body:

body {
    background-image: url(...);
}

In My cases, After installing Sql server data tools by Visual Studio 2015 installer, problem has been resolved

Here is the screenshot for installing data tools

I compare strings using = and not <>. I've found out that in this context = seems to work in more reasonable fashion than <>. I have specified that two empty (or NULL) strings are equal. The real implementation returns PL/SQL boolean, but here I changed that to pls_integer (0 is false and 1 is true) to be able easily demonstrate the function.

create or replace function is_equal(a in varchar2, b in varchar2)
return pls_integer as
begin
  if a is null and b is null then
    return 1;
  end if;

  if a = b then
    return 1;
  end if;

  return 0;
end;
/
show errors

begin
  /* Prints 0 */
  dbms_output.put_line(is_equal('AAA', 'BBB'));
  dbms_output.put_line(is_equal('AAA', null));
  dbms_output.put_line(is_equal(null, 'BBB'));
  dbms_output.put_line(is_equal('AAA', ''));
  dbms_output.put_line(is_equal('', 'BBB'));

  /* Prints 1 */
  dbms_output.put_line(is_equal(null, null));
  dbms_output.put_line(is_equal(null, ''));
  dbms_output.put_line(is_equal('', ''));
  dbms_output.put_line(is_equal('AAA', 'AAA'));
end;

$('input[id^="rad"]').dblclick(function(){
    var nombre = $(this).attr('id');
    var checked =  $(this).is(":checked") ;
    if(checked){
        $("input[id="+nombre+"]:radio").prop( "checked", false );
    }
});

Every time you have a double click in a checked radio the checked changes to false

My radios begin with id=radxxxxxxxx because I use this id selector.

In Angular you can define event listeners like in the example below:

<!-- Here you can call public methods from parental component -->
<input (change)="method_name()"> 

json.dump() will preserve the ordder of your dictionary. Open the file in a text editor and you will see. It will preserve the order regardless of whether you send it an OrderedDict.

But json.load() will lose the order of the saved object unless you tell it to load into an OrderedDict(), which is done with the object_pairs_hook parameter as J.F.Sebastian instructed above.

It would otherwise lose the order because under usual operation, it loads the saved dictionary object into a regular dict and a regular dict does not preserve the oder of the items it is given.

If the data is stored in a database it will be faster to send the query to the database instead of getting all data and query it in memory.

A third way to do it will be linq to datasets, but i doubt any of these 3 methods differ much in performance.

In SQL Server , cast text as datetime

select cast('5/21/2013 9:45:48' as datetime)

I found this funny example in terms of loose coupling:

Source: Understanding dependency injection

Any application is composed of many objects that collaborate with each other to perform some useful stuff. Traditionally each object is responsible for obtaining its own references to the dependent objects (dependencies) it collaborate with. This leads to highly coupled classes and hard-to-test code.

For example, consider a Car object.

A Car depends on wheels, engine, fuel, battery, etc. to run. Traditionally we define the brand of such dependent objects along with the definition of the Car object.

Without Dependency Injection (DI):

class Car{
  private Wheel wh = new NepaliRubberWheel();
  private Battery bt = new ExcideBattery();

  //The rest
}

Here, the Car object is responsible for creating the dependent objects.

What if we want to change the type of its dependent object - say Wheel - after the initial NepaliRubberWheel() punctures? We need to recreate the Car object with its new dependency say ChineseRubberWheel(), but only the Car manufacturer can do that.

Then what does the Dependency Injection do for us...?

When using dependency injection, objects are given their dependencies at run time rather than compile time (car manufacturing time). So that we can now change the Wheel whenever we want. Here, the dependency (wheel) can be injected into Car at run time.

After using dependency injection:

Here, we are injecting the dependencies (Wheel and Battery) at runtime. Hence the term : Dependency Injection. We normally rely on DI frameworks such as Spring, Guice, Weld to create the dependencies and inject where needed.

class Car{
  private Wheel wh; // Inject an Instance of Wheel (dependency of car) at runtime
  private Battery bt; // Inject an Instance of Battery (dependency of car) at runtime
  Car(Wheel wh,Battery bt) {
      this.wh = wh;
      this.bt = bt;
  }
  //Or we can have setters
  void setWheel(Wheel wh) {
      this.wh = wh;
  }
}

The advantages are:

• decoupling the creation of object (in other word, separate usage from the creation of object)
• ability to replace dependencies (eg: Wheel, Battery) without changing the class that uses it(Car)
• promotes "Code to interface not to implementation" principle
• ability to create and use mock dependency during test (if we want to use a Mock of Wheel during test instead of a real instance.. we can create Mock Wheel object and let DI framework inject to Car)

I was getting the same error message, but in my scenario I was trying to update entities derived from a many-to-many relationship using a PJT (Pure Join Table).

From reading the other posts, I thought I could fix it by adding an additional PK field to the join table... However, if you add a PK column to a join table, it is no longer a PJT and you lose all of the entity framework advantages like the automatic relationship mapping between the entities.

So the solution in my case was to alter the join table on the DB to make a PK that includes BOTH of the foreign ID columns.

Just use str.replace(',', '.') - it is both fast and efficient when a single character is to be replaced. And if the comma doesn't exist, it does nothing.

Font Squirrel has a wonderful web font generator.

I think you should find what you need here to generate OTF fonts and the needed CSS to use them. It will even support older IE versions.

EDIT: Just did some quick inspection of the string provided by the OP. The small "character" in front of the curly brace is a UTF-8 B(yte) O(rder) M(ark) 0xEF 0xBB 0xBF. I don't know why this byte sequence is displayed as ? here.

Essentially the system you aquire the data from sends it encoded in UTF-8 with a BOM preceding the data. You should remove the first three bytes from the string before you throw it into json_decode() (a substr($string, 3) will do).

string(62) "?{"action":"set","user":"123123123123","status":"OK"}"
            ^
            |
            This is the UTF-8 BOM

As Kuroki Kaze discovered, this character surely is the reason why json_decode fails. The string in its given form is not correctly a JSON formated structure (see RFC 4627)

The easiest solution is to use numpy.insert().

The Advantage of np.insert() over np.append is that you can insert the new columns into custom indices.

import numpy as np

X = np.arange(20).reshape(10,2)

X = np.insert(X, [0,2], np.random.rand(X.shape[0]*2).reshape(-1,2)*10, axis=1)

String timeStamp = new SimpleDateFormat("dd/MM/yyyy_HH:mm:ss").format(Calendar.getInstance().getTime());
System.out.println(timeStamp);

Below code from Python | How to Count the frequency of a word in the text file? worked for me.

 import re
    frequency = {}
    #Open the sample text file in read mode.
    document_text = open('sample.txt', 'r')
    #convert the string of the document in lowercase and assign it to text_string variable.
    text = document_text.read().lower()
    pattern = re.findall(r'\b[a-z]{2,15}\b', text)
    for word in pattern:
         count = frequency.get(word,0)
         frequency[word] = count + 1
     frequency_list = frequency.keys()
     for words in frequency_list:
         print(words, frequency[words])

OUTPUT:

Pseudo-elements are treated as descendants of their associated element. To position a pseudo-element below its parent, you have to create a new stacking context to change the default stacking order.
Positioning the pseudo-element (absolute) and assigning a z-index value other than “auto” creates the new stacking context.

#element { _x000D_
    position: relative;  /* optional */_x000D_
    width: 100px;_x000D_
    height: 100px;_x000D_
    background-color: blue;_x000D_
}_x000D_
_x000D_
#element::after {_x000D_
    content: "";_x000D_
    width: 150px;_x000D_
    height: 150px;_x000D_
    background-color: red;_x000D_
_x000D_
    /* create a new stacking context */_x000D_
    position: absolute;_x000D_
    z-index: -1;  /* to be below the parent element */_x000D_
}

better to use touchstart event with .on() jQuery method:

$(window).load(function() { // better to use $(document).ready(function(){
    $('.List li').on('click touchstart', function() {
        $('.Div').slideDown('500');
    });
});

And i don't understand why you are using $(window).load() method because it waits for everything on a page to be loaded, this tend to be slow, while you can use $(document).ready() method which does not wait for each element on the page to be loaded first.

I ran into the same issue just now. In my case, all I had to do is to make sure that the table I am referencing in the foreign key must be created prior to the current table (earlier in the code). So if you are referencing a variable (x*5) the system should know what x is (x must be declared in earlier lines of code). This resolved my issue, hope it'll help someone else.

A very simple solution is to add the database name with your table name like if your DB name is DBMS and table is info then it will be DBMS.info for any query.

If your query is

select * from STUDENTREC where ROLL_NO=1;

it might show an error but

select * from DBMS.STUDENTREC where ROLL_NO=1; 

it doesn't because now actually your table is found.

You could use a character class ([./-]) so that the seperators can be any of the defined characters

var dateReg = /^\d{2}[./-]\d{2}[./-]\d{4}$/

Or better still, match the character class for the first seperator, then capture that as a group ([./-]) and use a reference to the captured group \1 to match the second seperator, which will ensure that both seperators are the same:

var dateReg = /^\d{2}([./-])\d{2}\1\d{4}$/

"22-03-1981".match(dateReg) // matches
"22.03-1981".match(dateReg) // does not match
"22.03.1981".match(dateReg) // matches

Here's a good one:

Set line-height equal to whatever the height is; works like a charm!

E.g:

li {
    height: 30px;
    line-height: 30px;
}

You can use this in your MySQL WHERE clause to return records that were created within the last 7 days/week:

created >= DATE_SUB(CURDATE(),INTERVAL 7 day)

Also use NOW() in the subtraction to give hh:mm:ss resolution. So to return records created exactly (to the second) within the last 24hrs, you could do:

created >= DATE_SUB(NOW(),INTERVAL 1 day)

There is no way to display interactive elements on the lockscreen or wallpaper with a non jailbroken iPhone.

I would recommend Countdown Widget it's free an you can display countdowns in the notification center which you can also access from your lockscreen.

If you go there will be trouble, but if you stay it will be double.

I'd much rather go against some supposed non-plurals naming convention than name my table after something which might be a reserved word.

I'm assuming each entry in "ips" can have multiple name value pairs - so it's nested. You can achieve this data structure as such:

var ips = {}

function addIpId(ipID, name, value) {
    if (!ips[ipID]) ip[ipID] = {};
    var entries = ip[ipID];
    // you could add a check to ensure the name-value par's not already defined here
    var entries[name] = value;
}

An another solution

import java.util.Scanner;

public class Prime {
    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);

        int[] arr = new int[10000000];
        for(int i=2;i<10000000;i++)
        {
            arr[i]=i;
        }
        for(int i=2;i<10000000;i++)
            for(int j=i+i;j<10000000;j+=i)
                arr[j]=0;

        int t = in.nextInt();
        for(int a0 = 0; a0 < t; a0++){
            int n = in.nextInt();
            int count=0;
            for(int j=2;j<10000000;j++)
            {
                if(arr[j]!=0)
                {
                    count++;
                    if(count==n)
                    {
                        System.out.println(j);
                        break;
                    }
                }
            }
        }
    }
}

Hope this will help for larger numbers...

A hash is an fixed sized integer that identifies a particular value. Each value needs to have its own hash, so for the same value you will get the same hash even if it's not the same object.

>>> hash("Look at me!")
4343814758193556824
>>> f = "Look at me!"
>>> hash(f)
4343814758193556824

Hash values need to be created in such a way that the resulting values are evenly distributed to reduce the number of hash collisions you get. Hash collisions are when two different values have the same hash. Therefore, relatively small changes often result in very different hashes.

>>> hash("Look at me!!")
6941904779894686356

These numbers are very useful, as they enable quick look-up of values in a large collection of values. Two examples of their use are Python's set and dict. In a list, if you want to check if a value is in the list, with if x in values:, Python needs to go through the whole list and compare x with each value in the list values. This can take a long time for a long list. In a set, Python keeps track of each hash, and when you type if x in values:, Python will get the hash-value for x, look that up in an internal structure and then only compare x with the values that have the same hash as x.

The same methodology is used for dictionary lookup. This makes lookup in set and dict very fast, while lookup in list is slow. It also means you can have non-hashable objects in a list, but not in a set or as keys in a dict. The typical example of non-hashable objects is any object that is mutable, meaning that you can change its value. If you have a mutable object it should not be hashable, as its hash then will change over its life-time, which would cause a lot of confusion, as an object could end up under the wrong hash value in a dictionary.

Note that the hash of a value only needs to be the same for one run of Python. In Python 3.3 they will in fact change for every new run of Python:

$ /opt/python33/bin/python3
Python 3.3.2 (default, Jun 17 2013, 17:49:21) 
[GCC 4.6.3] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> hash("foo")
1849024199686380661
>>> 
$ /opt/python33/bin/python3
Python 3.3.2 (default, Jun 17 2013, 17:49:21) 
[GCC 4.6.3] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> hash("foo")
-7416743951976404299

This is to make is harder to guess what hash value a certain string will have, which is an important security feature for web applications etc.

Hash values should therefore not be stored permanently. If you need to use hash values in a permanent way you can take a look at the more "serious" types of hashes, cryptographic hash functions, that can be used for making verifiable checksums of files etc.

I wouldn't recommend the HAVING keyword for newbies, it is essentially for legacy purposes.

I am not clear on what is the key for this table (is it fully normalized, I wonder?), consequently I find it difficult to follow your specification:

I would like to find all records for all users that have more than one payment per day with the same account number... Additionally, there should be a filter than only counts the records whose ZIP code is different.

So I've taken a literal interpretation.

The following is more verbose but could be easier to understand and therefore maintain (I've used a CTE for the table PAYMENT_TALLIES but it could be a VIEW:

WITH PAYMENT_TALLIES (user_id, zip, tally)
     AS
     (
      SELECT user_id, zip, COUNT(*) AS tally
        FROM PAYMENT
       GROUP 
          BY user_id, zip
     )
SELECT DISTINCT *
  FROM PAYMENT AS P
 WHERE EXISTS (
               SELECT * 
                 FROM PAYMENT_TALLIES AS PT
                WHERE P.user_id = PT.user_id
                      AND PT.tally > 1
              );

Neither of the highest voted answers are correct on SQL Server 2000. Perhaps they were using a different version.

Here are the correct versions of both of them on SQL Server 2000.

select t.range as [score range], count(*) as [number of occurences]
from (
  select case  
    when score between 0 and 9 then ' 0- 9'
    when score between 10 and 19 then '10-19'
    else '20-99' end as range
  from scores) t
group by t.range

or

select t.range as [score range], count(*) as [number of occurrences]
from (
      select user_id,
         case when score >= 0 and score< 10 then '0-9'
         when score >= 10 and score< 20 then '10-19'
         else '20-99' end as range
     from scores) t
group by t.range

The second function should have:

var value = document.getElementById(id).value;

Then they are basically the same function.

For safe execution of code, use if-let block with Data to prevent app crash & , as function UIImagePNGRepresentation returns an optional value.

if let img = UIImage(named: "TestImage.png") {
    if let data:Data = UIImagePNGRepresentation(img) {
       // Handle operations with data here...         
    }
}

Note: Data is Swift 3+ class. Use Data instead of NSData with Swift 3+

Generic image operations (like png & jpg both):

if let img = UIImage(named: "TestImage.png") {  //UIImage(named: "TestImage.jpg")
        if let data:Data = UIImagePNGRepresentation(img) {
               handleOperationWithData(data: data)     
        } else if let data:Data = UIImageJPEGRepresentation(img, 1.0) {
               handleOperationWithData(data: data)     
        }
}

*******
func handleOperationWithData(data: Data) {
     // Handle operations with data here...
     if let image = UIImage(data: data) {
        // Use image...
     }
}

By using extension:

extension UIImage {

    var pngRepresentationData: Data? {
        return UIImagePNGRepresentation(self)
    }

    var jpegRepresentationData: Data? {
        return UIImageJPEGRepresentation(self, 1.0)
    }
}

*******
if let img = UIImage(named: "TestImage.png") {  //UIImage(named: "TestImage.jpg")
      if let data = img.pngRepresentationData {
              handleOperationWithData(data: data)     
      } else if let data = img.jpegRepresentationData {
              handleOperationWithData(data: data)     
     }
}

*******
func handleOperationWithData(data: Data) {
     // Handle operations with data here...
     if let image = UIImage(data: data) {
        // Use image...
     }
}

Try library(getopt) ... if you want things to be nicer. For example:

spec <- matrix(c(
        'in'     , 'i', 1, "character", "file from fastq-stats -x (required)",
        'gc'     , 'g', 1, "character", "input gc content file (optional)",
        'out'    , 'o', 1, "character", "output filename (optional)",
        'help'   , 'h', 0, "logical",   "this help"
),ncol=5,byrow=T)

opt = getopt(spec);

if (!is.null(opt$help) || is.null(opt$in)) {
    cat(paste(getopt(spec, usage=T),"\n"));
    q();
}

A bit like what @Hossein Hajizadeh alerady said, though in more detail:

There is an alternative to eval().

The function setTimeout() is designed to execute something after an interval of milliseconds, and the code to be executed just so happens to be formatted as a string.

It would work like this:

ExecuteJavascriptString(); //Just for running it_x000D_
_x000D_
function ExecuteJavascriptString()_x000D_
{_x000D_
    var s = "alert('hello')";_x000D_
    setTimeout(s, 1);_x000D_
}

1 means it will wait 1 millisecond before executing the string.

It might not be the most correct way to do it, but it works.

Reading this original article on The Code Project will help you a lot: Visual Representation of SQL Joins.

Run the hist() function without making a graph, log-transform the counts, and then draw the figure.

hist.data = hist(my.data, plot=F)
hist.data$counts = log(hist.data$counts, 2)
plot(hist.data)

It should look just like the regular histogram, but the y-axis will be log2 Frequency.

Just create a button element with jQuery, and add the event handler when you create it :

var div = $('<div />', {'data-role' : 'fieldcontain'}),
    btn = $('<input />', {
              type  : 'button',
              value : 'Dynamic Button',
              id    : 'btn_a',
              on    : {
                 click: function() {
                     alert ( this.value );
                 }
              }
          });

div.append(btn).appendTo( $('#pg_menu_content').empty() );

FIDDLE

You can solve that using display table.

Here is the updated JSFiddle that solves your problem.

CSS

.body {
    display: table;
    background-color: green;
}

.left-side {
    background-color: blue;
    float: none;
    display: table-cell;
    border: 1px solid;
}

.right-side {
    background-color: red;
    float: none;
    display: table-cell;
    border: 1px solid;
}

HTML

<div class="row body">
        <div class="col-xs-9 left-side">

Upon further analysis of this, I believe this is (at least partially) caused by the data alignment of the four-pointers. This will cause some level of cache bank/way conflicts.

If I've guessed correctly on how you are allocating your arrays, they are likely to be aligned to the page line.

This means that all your accesses in each loop will fall on the same cache way. However, Intel processors have had 8-way L1 cache associativity for a while. But in reality, the performance isn't completely uniform. Accessing 4-ways is still slower than say 2-ways.

EDIT: It does in fact look like you are allocating all the arrays separately. Usually when such large allocations are requested, the allocator will request fresh pages from the OS. Therefore, there is a high chance that large allocations will appear at the same offset from a page-boundary.

Here's the test code:

int main(){
    const int n = 100000;

#ifdef ALLOCATE_SEPERATE
    double *a1 = (double*)malloc(n * sizeof(double));
    double *b1 = (double*)malloc(n * sizeof(double));
    double *c1 = (double*)malloc(n * sizeof(double));
    double *d1 = (double*)malloc(n * sizeof(double));
#else
    double *a1 = (double*)malloc(n * sizeof(double) * 4);
    double *b1 = a1 + n;
    double *c1 = b1 + n;
    double *d1 = c1 + n;
#endif

    //  Zero the data to prevent any chance of denormals.
    memset(a1,0,n * sizeof(double));
    memset(b1,0,n * sizeof(double));
    memset(c1,0,n * sizeof(double));
    memset(d1,0,n * sizeof(double));

    //  Print the addresses
    cout << a1 << endl;
    cout << b1 << endl;
    cout << c1 << endl;
    cout << d1 << endl;

    clock_t start = clock();

    int c = 0;
    while (c++ < 10000){

#if ONE_LOOP
        for(int j=0;j<n;j++){
            a1[j] += b1[j];
            c1[j] += d1[j];
        }
#else
        for(int j=0;j<n;j++){
            a1[j] += b1[j];
        }
        for(int j=0;j<n;j++){
            c1[j] += d1[j];
        }
#endif

    }

    clock_t end = clock();
    cout << "seconds = " << (double)(end - start) / CLOCKS_PER_SEC << endl;

    system("pause");
    return 0;
}

Observations:

• 6.206 seconds with one loop and 2.116 seconds with two loops. This reproduces the OP's results exactly.

• In the first two tests, the arrays are allocated separately. You'll notice that they all have the same alignment relative to the page.

• In the second two tests, the arrays are packed together to break that alignment. Here you'll notice both loops are faster. Furthermore, the second (double) loop is now the slower one as you would normally expect.

As @Stephen Cannon points out in the comments, there is a very likely possibility that this alignment causes false aliasing in the load/store units or the cache. I Googled around for this and found that Intel actually has a hardware counter for partial address aliasing stalls:

http://software.intel.com/sites/products/documentation/doclib/stdxe/2013/~amplifierxe/pmw_dp/events/partial_address_alias.html

5 Regions - Explanations

Region 1:

This one is easy. The dataset is so small that the performance is dominated by overhead like looping and branching.

Region 2:

Here, as the data sizes increase, the amount of relative overhead goes down and the performance "saturates". Here two loops is slower because it has twice as much loop and branching overhead.

I'm not sure exactly what's going on here... Alignment could still play an effect as Agner Fog mentions cache bank conflicts. (That link is about Sandy Bridge, but the idea should still be applicable to Core 2.)

Region 3:

At this point, the data no longer fits in the L1 cache. So performance is capped by the L1 <-> L2 cache bandwidth.

Region 4:

The performance drop in the single-loop is what we are observing. And as mentioned, this is due to the alignment which (most likely) causes false aliasing stalls in the processor load/store units.

However, in order for false aliasing to occur, there must be a large enough stride between the datasets. This is why you don't see this in region 3.

Region 5:

At this point, nothing fits in the cache. So you're bound by memory bandwidth.

If you want to set something on a timer, you can use JavaScript's setTimeout or setInterval methods:

setTimeout ( expression, timeout );
setInterval ( expression, interval );

Where expression is a function and timeout and interval are integers in milliseconds. setTimeout runs the timer once and runs the expression once whereas setInterval will run the expression every time the interval passes.

So in your case it would work something like this:

setInterval(function() {
    //call $.ajax here
}, 5000); //5 seconds

As far as the Ajax goes, see jQuery's ajax() method. If you run an interval, there is nothing stopping you from calling the same ajax() from other places in your code.

If what you want is for an interval to run every 30 seconds until a user initiates a form submission...and then create a new interval after that, that is also possible:

setInterval() returns an integer which is the ID of the interval.

var id = setInterval(function() {
    //call $.ajax here
}, 30000); // 30 seconds

If you store that ID in a variable, you can then call clearInterval(id) which will stop the progression.

Then you can reinstantiate the setInterval() call after you've completed your ajax form submission.

It is an old question but i want to add that if you want to resize image according to viewport size only with css; you can use viewport units "vh (viewport height) or vw (viewport width)".

.img {
width: 100vw;
height: 100vh;
}

See browser supports

Below is how I got this working.

The Key point was: I needed to use the ViewModel associated with the view in order for the runtime to be able to resolve the object in the request.

[I know that that there is a way to bind an object other than the default ViewModel object but ended up simply populating the necessary properties for my needs as I could not get it to work]

[HttpPost]  
  public ActionResult GetDataForInvoiceNumber(MyViewModel myViewModel)  
  {            
     var invoiceNumberQueryResult = _viewModelBuilder.HydrateMyViewModelGivenInvoiceDetail(myViewModel.InvoiceNumber, myViewModel.SelectedCompanyCode);
     return Json(invoiceNumberQueryResult, JsonRequestBehavior.DenyGet);
  }

The JQuery script used to call this action method:

var requestData = {
         InvoiceNumber: $.trim(this.value),
         SelectedCompanyCode: $.trim($('#SelectedCompanyCode').val())

Use the concatenation operator +, and the fact that numeric types will convert automatically into strings:

var a = 1;
var b = "bob";
var c = b + a;

The ALL_DIRECTORIES data dictionary view will have information about all the directories that you have access to. That includes the operating system path

SELECT owner, directory_name, directory_path
  FROM all_directories

Here's my take on the problem. I create AbsoluteLayout overlay which contains Info Window (a regular view with every bit of interactivity and drawing capabilities). Then I start Handler which synchronizes the info window's position with position of point on the map every 16 ms. Sounds crazy, but actually works.

Through personal expeirence I've found that it's not possible to round corners of an HTML table cell with pure CSS. Rounding a table's outermost border is possible.

You will have to resort to using images as described in this tutorial, or any similar :)

In Oracle the solution would be:

UPDATE
    MasterTbl
SET
    (TotalX,TotalY,TotalZ) =
      (SELECT SUM(X),SUM(Y),SUM(Z)
         from DetailTbl where DetailTbl.MasterID = MasterTbl.ID)

Don't know if your system allows the same.

The meaning of final in java is: -applied to a variable means that the respective variable once initialized can no longer be modified

private final double numer = 12;

If you try to modify this value, you will get an error.

-applied to a method means that the respective method can't be override

 public final void displayMsg()
    {
        System.out.println("I'm in Base class - displayMsg()");
    }

But final method can be inherited because final keyword restricts the redefinition of the method.

-applied to a class means that the respective class can't be extended.

class Base
{

    public void displayMsg()
    {
        System.out.println("I'm in Base class - displayMsg()");
    }
}

The meaning of finally is :

class TestFinallyBlock{  
  public static void main(String args[]){  
  try{  
   int data=25/5;  
   System.out.println(data);  
  }  
  catch(NullPointerException e){System.out.println(e);}  
  finally{System.out.println("finally block is always executed");}  
  System.out.println("rest of the code...");  
  }  
} 

in this exemple even if the try-catch is executed or not, what is inside of finally will always be executed. The meaning of finalize:

class FinalizeExample{  
public void finalize(){System.out.println("finalize called");}  
public static void main(String[] args){  
FinalizeExample f1=new FinalizeExample();  
FinalizeExample f2=new FinalizeExample();  
f1=null;  
f2=null;  
System.gc();  
}}  

before calling the Garbage Collector.

A multiple select is really just a select with a multiple attribute. With that in mind, it should be as easy as...

Form::select('sports[]', $sports, null, array('multiple'))

The first parameter is just the name, but post-fixing it with the [] will return it as an array when you use Input::get('sports').

The second parameter is an array of selectable options.

The third parameter is an array of options you want pre-selected.

The fourth parameter is actually setting this up as a multiple select dropdown by adding the multiple property to the actual select element..

Underscore-java library has static method U.jsonToXml(jsonstring). I am the maintainer of the project. Live example

import com.github.underscore.lodash.U;

public class MyClass {
    public static void main(String args[]) {
        String json = "{\"name\":\"JSON\",\"integer\":1,\"double\":2.0,\"boolean\":true,\"nested\":{\"id\":42},\"array\":[1,2,3]}";  
        System.out.println(json); 
        String xml = U.jsonToXml(json);  
        System.out.println(xml); 
    }
}

Output:

{"name":"JSON","integer":1,"double":2.0,"boolean":true,"nested":{"id":42},"array":[1,2,3]}
<?xml version="1.0" encoding="UTF-8"?>
<root>
  <name>JSON</name>
  <integer number="true">1</integer>
  <double number="true">2.0</double>
  <boolean boolean="true">true</boolean>
  <nested>
    <id number="true">42</id>
  </nested>
  <array number="true">1</array>
  <array number="true">2</array>
  <array number="true">3</array>
</root>

Based on @Halil great answer, here is simple function how to insert new element after a specific key, while preserving integer keys:

private function arrayInsertAfterKey($array, $afterKey, $key, $value){
    $pos   = array_search($afterKey, array_keys($array));

    return array_merge(
        array_slice($array, 0, $pos, $preserve_keys = true),
        array($key=>$value),
        array_slice($array, $pos, $preserve_keys = true)
    );
} 

alter pluggable database orclpdb open;`

worked for me.

orclpdb is the name of pluggable database which may be different based on the individual.

Bootstrap tabs are not responsive out of the box. Responsive, IMO, is a style change, changing functions is Adaptive. There are a few plugins to turn the Bootstrap 3 tabs into a Collapse component. The best and most updated one is : https://github.com/flatlogic/bootstrap-tabcollapse.

Here's one way of implementing it:

DEMO: http://jsbin.com/zibani/1/

EDIT: http://jsbin.com/zibani/1/edit

This turns the content into a collapse component:

Dependencies:

1. Bootstrap 3.2 css or higher but still in the 3 series
2. Bootstrap 3.2 jQuery or higher but still in the 3 series
3. Compatible version of bootstrap-tabcollapse.js

HTML -- same as question with class name addition:

       <ul class="nav nav-tabs content-tabs" id="maincontent" role="tablist">

jQuery:

$(document).ready(function() {

    // DEPENDENCY: https://github.com/flatlogic/bootstrap-tabcollapse
    $('.content-tabs').tabCollapse();

    // initialize tab function
    $('.nav-tabs a').click(function(e) {
        e.preventDefault();
        $(this).tab('show');
    });

});

CSS -- optional for fat fingers and active states:

.panel-heading {
    padding: 0
}
.panel-heading a {
    display: block;
    padding: 20px 10px;
}
.panel-heading a.collapsed {
    background: #fff
}
.panel-heading a {
    background: #f7f7f7;
    border-radius: 5px;
}
.panel-heading a:after {
    content: '-'
}
.panel-heading a.collapsed:after {
    content: '+'
}
.nav.nav-tabs li a,
.nav.nav-tabs li.active > a:hover,
.nav.nav-tabs li.active > a:active,
.nav.nav-tabs li.active > a:focus {
    border-bottom-width: 0px;
    outline: none;
}
.nav.nav-tabs li a {
    padding-top: 20px;
    padding-bottom: 20px;
}
.tab-pane {
    background: #fff;
    padding: 10px;
    border: 1px solid #ddd;
    margin-top: -1px;
}

I have had to unpack a .ab-file, too and found this post while looking for an answer. My suggested solution is Android Backup Extractor, a free Java tool for Windows, Linux and Mac OS.

Make sure to take a look at the README, if you encounter a problem. You might have to download further files, if your .ab-file is password-protected.

Usage:

java -jar abe.jar [-debug] [-useenv=yourenv] unpack <backup.ab> <backup.tar> [password]

Example:

Let's say, you've got a file test.ab, which is not password-protected, you're using Windows and want the resulting .tar-Archive to be called test.tar. Then your command should be:

java.exe -jar abe.jar unpack test.ab test.tar ""

There is no direct string compare function in SQL Server

CASE
  WHEN str1 = str2 THEN 0
  WHEN str1 < str2 THEN -1
  WHEN str1 > str2 THEN 1
  ELSE NULL --one of the strings is NULL so won't compare (added on edit)
END

Notes

• you can wraps this via a UDF using CREATE FUNCTION etc
• you may need NULL handling (in my code above, any NULL will report 1)
• str1 and str2 will be column names or @variables

You can download the list here: ftp://ftp.cis.upenn.edu/pub/treebank/doc/tagguide.ps.gz. It includes confusing parts of speech, capitalization, and other conventions. Also, wikipedia has an interesting section similar to this. Section: Part-of-speech tags used.

Eclipse C/C++ does not recognize the symbol std::unique_ptr even though you have included the C++11 memory header in your file.

Assuming you are using the GNU C++ compiler, this is what I did to fix:

Project -> Properties -> C/C++ General -> Preprocessor Include Paths -> GNU C++ -> CDT User Setting Entries

1. Click on the "Add..." button

2. Select "Preprocessor Macro" from the dropdown menu

   Name: __cplusplus     Value:  201103L
   

3. Hit Apply, and then OK to go back to your project

4. Then rebuild you C++ index: Projects -> C/C++ Index -> Rebuild

on IOS 9, you can do this

let alert = UIAlertController(title: "Alert", message: "Message", preferredStyle: UIAlertControllerStyle.alert)
alert.addAction(UIAlertAction(title: "Click", style: UIAlertActionStyle.default, handler: nil))
self.present(alert, animated: true, completion: nil)

As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers. Users of older versions of jQuery should use .delegate() in preference to .live(). Refer: http://api.jquery.com/on/

$('#imageFile').on("change", function(){ uploadFile(); });

You can create a bitmap transfer. try this....

In the first class:

1) Create:

private static Bitmap bitmap_transfer;

2) Create getter and setter

public static Bitmap getBitmap_transfer() {
    return bitmap_transfer;
}

public static void setBitmap_transfer(Bitmap bitmap_transfer_param) {
    bitmap_transfer = bitmap_transfer_param;
}

3) Set the image:

ImageView image = (ImageView) view.findViewById(R.id.image);
image.buildDrawingCache();
setBitmap_transfer(image.getDrawingCache());

Then, in the second class:

ImageView image2 = (ImageView) view.findViewById(R.id.img2);
imagem2.setImageDrawable(new BitmapDrawable(getResources(), classe1.getBitmap_transfer()));

You were missing the small icon. I did the same mistake and the above step resolved it.

As per the official documentation: A Notification object must contain the following:

1. A small icon, set by setSmallIcon()

2. A title, set by setContentTitle()

3. Detail text, set by setContentText()

4. On Android 8.0 (API level 26) and higher, a valid notification channel ID, set by setChannelId() or provided in the NotificationCompat.Builder constructor when creating a channel.

See http://developer.android.com/guide/topics/ui/notifiers/notifications.html

There is already a string handling function Series.str.startswith(). You should try foo[foo.b.str.startswith('f')].

Result:

    a   b
1   2   foo
2   3   fat

I think what you expect.

Alternatively you can use contains with regex option. For example:

foo[foo.b.str.contains('oo', regex= True, na=False)]

Result:

    a   b
1   2   foo

na=False is to prevent Errors in case there is nan, null etc. values

Aside from readability and performance, one aspect commonly overlooked is consistency. There are many ways to implement a for (or while) loop over iterators, from:

for (C::iterator iter = c.begin(); iter != c.end(); iter++) {
    do_something(*iter);
}

to:

C::iterator iter = c.begin();
C::iterator end = c.end();
while (iter != end) {
    do_something(*iter);
    ++iter;
}

with many examples in between at varying levels of efficiency and bug potential.

Using for_each, however, enforces consistency by abstracting away the loop:

for_each(c.begin(), c.end(), do_something);

The only thing you have to worry about now is: do you implement the loop body as function, a functor, or a lambda using Boost or C++0x features? Personally, I'd rather worry about that than how to implement or read a random for/while loop.

If you don't want to modify the dataframe, you could use a custom formatter for that column.

import pandas as pd
pd.options.display.float_format = '${:,.2f}'.format
df = pd.DataFrame([123.4567, 234.5678, 345.6789, 456.7890],
                  index=['foo','bar','baz','quux'],
                  columns=['cost'])


print df.to_string(formatters={'cost':'${:,.2f}'.format})

yields

        cost
foo  $123.46
bar  $234.57
baz  $345.68
quux $456.79

I know it's 2 years since this question was asked and answered, but here's another function that sorts a two-dimensional array. It accepts a variable number of arguments, allowing you to pass in more than one key (ie column name) to sort by. PHP 5.3 required.

function sort_multi_array ($array, $key)
{
  $keys = array();
  for ($i=1;$i<func_num_args();$i++) {
    $keys[$i-1] = func_get_arg($i);
  }

  // create a custom search function to pass to usort
  $func = function ($a, $b) use ($keys) {
    for ($i=0;$i<count($keys);$i++) {
      if ($a[$keys[$i]] != $b[$keys[$i]]) {
        return ($a[$keys[$i]] < $b[$keys[$i]]) ? -1 : 1;
      }
    }
    return 0;
  };

  usort($array, $func);

  return $array;
}

Try it here: http://www.exorithm.com/algorithm/view/sort_multi_array

For doing FORM posts, the best way is to use WebClient.UploadValues() with a POST method.

If you are not using any javascript/jquery for form validation, then a simple layout for your form would look like this.

within the body of your html document:

<form action="formHandler.php" name="yourForm" id="theForm" method="post">    
    <input type="text" name="fname" id="fname" />    
    <input type="submit" value="submit"/>
</form>

You need to ensure you have the submit button within the form tags, and an appropriate action assigned. Such as sending to a php file.

For a more direct answer, provide the code you are working with.

You may find the following of use: http://www.w3.org/TR/html401/interact/forms.html

"Vanilla JS” is an expression that got popular after the publishing of a satire website in 2012 (http://vanilla-js.com/). There’s a section covering its story/meaning in this post.

So why the joke? It kind of came as a modern response to the old school knee-jerk reflex of relying on jQuery and additional JS libraries. With the ECMAScript spec and modern browsers capabilities, the need to bypass plain JS with external libraries to maintain consistency across browsers just isn’t there anymore. Here’s a site that shows you how true this is with concrete examples: http://youmightnotneedjquery.com/

From your local machine:

rsync -chavzP --stats [email protected]:/path/to/copy /path/to/local/storage

From your local machine with a non standard ssh port:

rsync -chavzP -e "ssh -p $portNumber" [email protected]:/path/to/copy /local/path

Or from the remote host, assuming you really want to work this way and your local machine is listening on SSH:

rsync -chavzP --stats /path/to/copy [email protected]:/path/to/local/storage

See man rsync for an explanation of my usual switches.

Notice that instance methods are also attributes (of the class) and that you could set them at the class or instance level if you really wanted to be a badass. Or that you may set a class variable (which is also an attribute of the class), where handy readonly properties won't work neatly out of the box. What I'm trying to say is that the "readonly attribute" problem is in fact more general than it's usually perceived to be. Fortunately there are conventional expectations at work that are so strong as to blind us wrt these other cases (after all, almost everything is an attribute of some sort in python).

Building upon these expectations I think the most general and lightweight approach is to adopt the convention that "public" (no leading underscore) attributes are readonly except when explicitly documented as writeable. This subsumes the usual expectation that methods won't be patched and class variables indicating instance defaults are better let alone. If you feel really paranoid about some special attribute, use a readonly descriptor as a last resource measure.

how does rails know that user_id is a foreign key referencing user?

Rails itself does not know that user_id is a foreign key referencing user. In the first command rails generate model Micropost user_id:integer it only adds a column user_id however rails does not know the use of the col. You need to manually put the line in the Micropost model

class Micropost < ActiveRecord::Base
  belongs_to :user
end

class User < ActiveRecord::Base
  has_many :microposts
end

the keywords belongs_to and has_many determine the relationship between these models and declare user_id as a foreign key to User model.

The later command rails generate model Micropost user:references adds the line belongs_to :user in the Micropost model and hereby declares as a foreign key.

FYI
Declaring the foreign keys using the former method only lets the Rails know about the relationship the models/tables have. The database is unknown about the relationship. Therefore when you generate the EER Diagrams using software like MySql Workbench you find that there is no relationship threads drawn between the models. Like in the following pic

However, if you use the later method you find that you migration file looks like:

def change
    create_table :microposts do |t|
      t.references :user, index: true

      t.timestamps null: false
    end
    add_foreign_key :microposts, :users

Now the foreign key is set at the database level. and you can generate proper EER diagrams.

This is oldschool and predates PowerShell, but I have used the qwinsta / rwinsta combo for YEARS to remotely log off stale RDP sessions. It's built in on at least Windows XP and forward (possibly earlier)

Determine the session ID:

qwinsta /SERVER:<NAME>

Remove the session in question:

rwinsta <SESSION_ID> /SERVER:<NAME>

I landed here looking for a solution for the case where I dont use data binding. Nothing worked for me but I got it in the end with:

dataGridView.Columns.Clear(); 
dataGridView.Rows.Clear();
dataGridView.Refresh();

Since PHP 5.5, you can use array_column:

$ids = array_column($users, 'id');

This is the preferred option on any modern project. However, if you must support PHP<5.5, the following alternatives exist:

Since PHP 5.3, you can use array_map with an anonymous function, like this:

$ids = array_map(function ($ar) {return $ar['id'];}, $users);

Before ^{_{(Technically PHP 4.0.6+)}}, you must create an anonymous function with create_function instead:

$ids = array_map(create_function('$ar', 'return $ar["id"];'), $users);

I think it is better to update your "mysql-connector" lib package, so database can be still more safe.

I am using mysql of version 8.0.12. When I updated the mysql-connector-java to version 8.0.11, the problem was gone.

In my case, I stumbled upon one issue with using printf solution:

$ printf "%x" 008 bash: printf: 008: invalid octal number

The easiest way was to use solution with bc, suggested in post higher:

$ bc <<< "obase=16; 008" 8

If you are using Eclipse IDE then go inside Window menu and select preferences and there you search for installed JREs and select the JRE you need to build the project

I've built a function that deals with plotting FFT of real signals. The extra bonus in my function relative to the previous answers is that you get the actual amplitude of the signal.

Also, because of the assumption of a real signal, the FFT is symmetric, so we can plot only the positive side of the x-axis:

import matplotlib.pyplot as plt
import numpy as np
import warnings


def fftPlot(sig, dt=None, plot=True):
    # Here it's assumes analytic signal (real signal...) - so only half of the axis is required

    if dt is None:
        dt = 1
        t = np.arange(0, sig.shape[-1])
        xLabel = 'samples'
    else:
        t = np.arange(0, sig.shape[-1]) * dt
        xLabel = 'freq [Hz]'

    if sig.shape[0] % 2 != 0:
        warnings.warn("signal preferred to be even in size, autoFixing it...")
        t = t[0:-1]
        sig = sig[0:-1]

    sigFFT = np.fft.fft(sig) / t.shape[0]  # Divided by size t for coherent magnitude

    freq = np.fft.fftfreq(t.shape[0], d=dt)

    # Plot analytic signal - right half of frequence axis needed only...
    firstNegInd = np.argmax(freq < 0)
    freqAxisPos = freq[0:firstNegInd]
    sigFFTPos = 2 * sigFFT[0:firstNegInd]  # *2 because of magnitude of analytic signal

    if plot:
        plt.figure()
        plt.plot(freqAxisPos, np.abs(sigFFTPos))
        plt.xlabel(xLabel)
        plt.ylabel('mag')
        plt.title('Analytic FFT plot')
        plt.show()

    return sigFFTPos, freqAxisPos


if __name__ == "__main__":
    dt = 1 / 1000

    # Build a signal within Nyquist - the result will be the positive FFT with actual magnitude
    f0 = 200  # [Hz]
    t = np.arange(0, 1 + dt, dt)
    sig = 1 * np.sin(2 * np.pi * f0 * t) + \
        10 * np.sin(2 * np.pi * f0 / 2 * t) + \
        3 * np.sin(2 * np.pi * f0 / 4 * t) +\
        7.5 * np.sin(2 * np.pi * f0 / 5 * t)

    # Result in frequencies
    fftPlot(sig, dt=dt)
    # Result in samples (if the frequencies axis is unknown)
    fftPlot(sig)

There is an experimental release by Microsoft of Interactive Extensions to LINQ (also on NuGet, see RxTeams's profile for more links). The Channel 9 video explains it well.

Its docs are only provided in XML format. I have run this documentation in Sandcastle to allow it to be in a more readable format. Unzip the docs archive and look for index.html.

Among many other goodies, it provides the expected ForEach implementation. It allows you to write code like this:

int[] numbers = { 1, 2, 3, 4, 5, 6, 7, 8 };

numbers.ForEach(x => Console.WriteLine(x*x));

I also faced this type of issue.I am using tomcat server then i put endorsed folder in tomcat then its start working.And also i replaced JDK1.6 with 1.7 then also its working.Finally i learn SSL then I resolved this type of issues.First you need to download the certificates from that servie provider server.then you are handshake is successfull. 1.Try to put endorsed folder in your server Next way 2.use jdk1.7

Next 3.Try to download valid certificates using SSL

The short answer is adb is used via command line. find adb.exe on your machine, add it to the path and use it from cmd on windows.

"adb devices" will give you a list of devices adb can talk to. your emulation platform should be on the list. just type adb to get a list of commands and what they do.

You can use AppendAllText instead:

File.AppendAllText(filePath, csv);

As the documentation of WriteAllText says:

If the target file already exists, it is overwritten

Also, note that your current code is not using proper new lines, for example in Notepad you'll see it all as one long line. Change the code to this to have proper new lines:

string csv = string.Format("{0},{1}{2}", first, image, Environment.NewLine);

Use execfile for Python 2:

>>> execfile('C:\\test.py')

Use exec for Python 3

>>> exec(open("C:\\test.py").read())

Kotlin with Coroutines

In Kotlin, using coroutines you can do the following:

CoroutineScope(Dispatchers.Main).launch { // Main, because UI is changed
    ticker(delayMillis = 1000, initialDelayMillis = 1000).consumeEach {
        tv.append("Hello World")
    }
}

This works for me

 var link_click = $('#google').get(0).attributes.onclick.nodeValue;
 console.log(link_click);

Use $ne -- $not should be followed by the standard operator:

An examples for $ne, which stands for not equal:

use test
switched to db test
db.test.insert({author : 'me', post: ""})
db.test.insert({author : 'you', post: "how to query"})
db.test.find({'post': {$ne : ""}})
{ "_id" : ObjectId("4f68b1a7768972d396fe2268"), "author" : "you", "post" : "how to query" }

And now $not, which takes in predicate ($ne) and negates it ($not):

db.test.find({'post': {$not: {$ne : ""}}})
{ "_id" : ObjectId("4f68b19c768972d396fe2267"), "author" : "me", "post" : "" }

For a Table:

SELECT 
  TABLE_NAME,COLUMN_NAME,CONSTRAINT_NAME, REFERENCED_TABLE_NAME,REFERENCED_COLUMN_NAME
FROM
  INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE
  REFERENCED_TABLE_SCHEMA = '<database>' AND
  REFERENCED_TABLE_NAME = '<table>';

For a Column:

SELECT 
  TABLE_NAME,COLUMN_NAME,CONSTRAINT_NAME, REFERENCED_TABLE_NAME,REFERENCED_COLUMN_NAME
FROM
  INFORMATION_SCHEMA.KEY_COLUMN_USAGE
WHERE
  REFERENCED_TABLE_SCHEMA = '<database>' AND
  REFERENCED_TABLE_NAME = '<table>' AND
  REFERENCED_COLUMN_NAME = '<column>';

Basically, we changed REFERENCED_TABLE_NAME with REFERENCED_COLUMN_NAME in the where clause.

You can use onclick to run some JavaScript or jQuery code before submitting the form like this:

<script type="text/javascript">
    beforeSubmit = function(){
        if (1 == 1){
            //your before submit logic
        }        
        $("#formid").submit();            
    }
</script>
<input type="button" value="Click" onclick="beforeSubmit();" />

From MSDN

// Create a request using a URL that can receive a post. 
WebRequest request = WebRequest.Create ("http://contoso.com/PostAccepter.aspx ");
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
string postData = "This is a test that posts this string to a Web server.";
byte[] byteArray = Encoding.UTF8.GetBytes (postData);
// Set the ContentType property of the WebRequest.
request.ContentType = "application/x-www-form-urlencoded";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream ();
// Write the data to the request stream.
dataStream.Write (byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close ();
// Get the response.
WebResponse response = request.GetResponse ();
// Display the status.
Console.WriteLine (((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream ();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader (dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd ();
// Display the content.
Console.WriteLine (responseFromServer);
// Clean up the streams.
reader.Close ();
dataStream.Close ();
response.Close ();

Take into account that the information must be sent in the format key1=value1&key2=value2

Another method:

SELECT * 
FROM (
    SELECT * FROM table_name
    ORDER BY date ASC, time ASC 
) AS sub
GROUP BY name

GROUP BY groups on the first matching result it hits. If that first matching hit happens to be the one you want then everything should work as expected.

I prefer this method as the subquery makes logical sense rather than peppering it with other conditions.

public static String concatStringsWSep(Iterable<String> strings, String separator) {
    StringBuilder sb = new StringBuilder();
    String sep = "";
    for(String s: strings) {
        sb.append(sep).append(s);
        sep = separator;
    }
    return sb.toString();                           
}

Try this code:

    Select Case aSheet.Name

        Case "ID Sheet", "Summary"
            Application.DisplayAlerts = False
            aSheet.Delete
            Application.DisplayAlerts = True

    End Select

Next aSheet

Since you look like you're going to be using this in a linux/cygwin environment, you want to use popen. It's like opening a file, only you'll get the executing programs stdout, so you can use your normal fscanf, fread etc.

The correct syntax is to tell Rsync to use a custom SSH command (adding -p 2222), which creates a secure tunnel to remote side using SSH, then connects via localhost:873

rsync -rvz --progress --remove-sent-files -e "ssh -p 2222" ./dir user@host/path

Rsync runs as a daemon on TCP port 873, which is not secure.

From Rsync man:

Push: rsync [OPTION...] SRC... [USER@]HOST:DEST

Which misleads people to try this:

rsync -rvz --progress --remove-sent-files ./dir user@host:2222/path

However, that is instructing it to connect to Rsync daemon on port 2222, which is not there.

$cookie_name = "my cookie";
$cookie_value = "my value";
$cookie_new_value = "my new value";

// Create a cookie,
setcookie($cookie_name, $cookie_value , time() + (86400 * 30), "/"); //86400 = 24 hours in seconds

// Get value in a cookie,
$cookie_value = $_COOKIE[$cookie_name];

// Update a cookie,
setcookie($cookie_name, $cookie_new_value , time() + (86400 * 30), "/");

// Delete a cookie,
setcookie($cookie_name, '' , time() - 3600, "/"); //  time() - 3600 means, set the cookie expiration date to the past hour.

Bootstrap 4

Now that BS4 is flexbox, the fixed-fluid is simple. Just set the width of the fixed column, and use the .col class on the fluid column.

.sidebar {
    width: 180px;
    min-height: 100vh;
}

<div class="row">
    <div class="sidebar p-2">Fixed width</div>
    <div class="col bg-dark text-white pt-2">
        Content
    </div>
</div>

Bootstrap 3..

One approach to a fixed-fluid layout is using media queries that align with Bootstrap's breakpoints so that you only use the fixed width columns are larger screens and then let the layout stack responsively on smaller screens...

@media (min-width:768px) {
  #sidebar {
      min-width: 300px;
      max-width: 300px;
  }
  #main {
      width:calc(100% - 300px);
  }
}

Find out the format of the floating point numbers used on the CPU that directly supports floating point and break it down into those parts. The most common format is IEEE-754.

Alternatively, you could obtain those parts using a few special functions (double frexp(double value, int *exp); and double ldexp(double x, int exp);) as shown in this answer.

Another option is to use %a with printf().

Create a table with column as type json

CREATE TABLE friends ( id serial primary key, data jsonb);

Now let's insert json data

INSERT INTO friends(data) VALUES ('{"name": "Arya", "work": ["Improvements", "Office"], "available": true}');
INSERT INTO friends(data) VALUES ('{"name": "Tim Cook", "work": ["Cook", "ceo", "Play"], "uses": ["baseball", "laptop"], "available": false}');

Now let's make some queries to fetch data

select data->'name' from friends;
select data->'name' as name, data->'work' as work from friends;

You might have noticed that the results comes with inverted comma( " ) and brackets ([ ])

    name    |            work            
------------+----------------------------
 "Arya"     | ["Improvements", "Office"]
 "Tim Cook" | ["Cook", "ceo", "Play"]
(2 rows)

Now to retrieve only the values just use ->>

select data->>'name' as name, data->'work'->>0 as work from friends;
select data->>'name' as name, data->'work'->>0 as work from friends where data->>'name'='Arya';

In case of a very large stream length there is the hazard of memory leak due to Large Object Heap. i.e. The byte buffer created by stream.ToArray creates a copy of memory stream in Heap memory leading to duplication of reserved memory. I would suggest to use a StreamReader, a TextWriter and read the stream in chunks of char buffers.

In netstandard2.0 System.IO.StreamReader has a method ReadBlock

you can use this method in order to read the instance of a Stream (a MemoryStream instance as well since Stream is the super of MemoryStream):

private static string ReadStreamInChunks(Stream stream, int chunkLength)
{
    stream.Seek(0, SeekOrigin.Begin);
    string result;
    using(var textWriter = new StringWriter())
    using (var reader = new StreamReader(stream))
    {
        var readChunk = new char[chunkLength];
        int readChunkLength;
        //do while: is useful for the last iteration in case readChunkLength < chunkLength
        do
        {
            readChunkLength = reader.ReadBlock(readChunk, 0, chunkLength);
            textWriter.Write(readChunk,0,readChunkLength);
        } while (readChunkLength > 0);

        result = textWriter.ToString();
    }

    return result;
}

NB. The hazard of memory leak is not fully eradicated, due to the usage of MemoryStream, that can lead to memory leak for large memory stream instance (memoryStreamInstance.Size >85000 bytes). You can use Recyclable Memory stream, in order to avoid LOH. This is the relevant library

Intl Means :Internationalization extension which enables programmers to perform UCA-conformant collation and number,currency,date,time formatting in PHP scripts.

To enable PHP Intl with PECL can be used.

pecl install intl

On a plain RHEL/CentOS/Fedora, PHP Intl can be install using yum

yum install php-intl

On Ubuntu, PHP Intl can be install using apt-get

 apt-get install php5-intl

Restart Apache service for the changes to take effect.

That's it

why is my java logging not working

provides a jar file that will help you work out why your logging in not working as expected. It gives you a complete dump of what loggers and handlers have been installed and what levels are set and at which level in the logging hierarchy.

Atomic properties :- When a variable assigned with atomic property that means it has only one thread access and it will be thread safe and will be good in performance perspective, will have default behaviour.

Non Atomic Properties :- When a variable assigned with atomic property that means it has multi thread access and it will not be thread safe and will be slow in performance perspective, will have default behaviour and when two different threads want to access variable at same time it will give unexpected results.

import datetime

timestamp = datetime.datetime.fromtimestamp(1500000000)

print(timestamp.strftime('%Y-%m-%d %H:%M:%S'))

Building on Matías Fidemraizer's answer, here is a version that supports binding to object properties other than strings.

using System.Collections.Generic;
using System.Linq;
using System.Reflection;

namespace WebOpsApi.Shared.Helpers
{
    public static class MappingExtension
    {
        public static T ToObject<T>(this IDictionary<string, object> source)
            where T : class, new()
        {
            var someObject = new T();
            var someObjectType = someObject.GetType();

            foreach (var item in source)
            {
                var key = char.ToUpper(item.Key[0]) + item.Key.Substring(1);
                var targetProperty = someObjectType.GetProperty(key);


                if (targetProperty.PropertyType == typeof (string))
                {
                    targetProperty.SetValue(someObject, item.Value);
                }
                else
                {

                    var parseMethod = targetProperty.PropertyType.GetMethod("TryParse",

                        }

                    }
                }
            }

            return someObject;
        }

        public static IDictionary<string, object> AsDictionary(this object source, BindingFlags bindingAttr = BindingFlags.DeclaredOnly | BindingFlags.Public | BindingFlags.Instance)
        {
            return source.GetType().GetProperties(bindingAttr).ToDictionary
            (
                propInfo => propInfo.Name,
                propInfo => propInfo.GetValue(source, null)
            );
        }
    }
}

In the last answer, you don't need to make a list from numbers; it is already a list:

numbers = [1, 2, 3]
numsum = sum(numbers)
print(numsum)

First you have to add System.Configuration reference to your project and then use below code to get connection string.

_connectionString = ConfigurationManager.ConnectionStrings["MYSQLConnection"].ConnectionString.ToString();

ldd -v prints the dependency tree under "Version information:' section. The first block in that section are the direct dependencies of the binary.

Try Using this- Spring 4.0. Working

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:p="http://www.springframework.org/schema/p"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:context="http://www.springframework.org/schema/context" 
       xsi:schemaLocation="http://www.springframework.org/schema/beans                                               http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/context 
       http://www.springframework.org/schema/context/spring-context.xsd"> 

It can often be very handy to use namedtuple. For example, you have a dictionary of 'name' as keys and 'score' as values and you want to sort on 'score':

import collections
Player = collections.namedtuple('Player', 'score name')
d = {'John':5, 'Alex':10, 'Richard': 7}

sorting with lowest score first:

worst = sorted(Player(v,k) for (k,v) in d.items())

sorting with highest score first:

best = sorted([Player(v,k) for (k,v) in d.items()], reverse=True)

Now you can get the name and score of, let's say the second-best player (index=1) very Pythonically like this:

player = best[1]
player.name
    'Richard'
player.score
    7

At the time of writing this, I was not aware of PreferredSize. Cinn's answer is better to achieve this.

You can create your own custom widget with a custom height:

import "package:flutter/material.dart";

class Page extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return new Column(children : <Widget>[new CustomAppBar("Custom App Bar"), new Container()],);
  }
}


class CustomAppBar extends StatelessWidget {

  final String title;
  final double barHeight = 50.0; // change this for different heights 

  CustomAppBar(this.title);

  @override
  Widget build(BuildContext context) {
    final double statusbarHeight = MediaQuery
        .of(context)
        .padding
        .top;

    return new Container(
      padding: new EdgeInsets.only(top: statusbarHeight),
      height: statusbarHeight + barHeight,
      child: new Center(
        child: new Text(
          title,
          style: new TextStyle(fontSize: 20.0, fontWeight: FontWeight.bold),
        ),
      ),
    );
  }
}

I've found my optimal blocksize to be 8 MB (equal to disk cache?) I needed to wipe (some say: wash) the empty space on a disk before creating a compressed image of it. I used:

cd /media/DiskToWash/
dd if=/dev/zero of=zero bs=8M; rm zero

I experimented with values from 4K to 100M.

After letting dd to run for a while I killed it (Ctlr+C) and read the output:

36+0 records in
36+0 records out
301989888 bytes (302 MB) copied, 15.8341 s, 19.1 MB/s

As dd displays the input/output rate (19.1MB/s in this case) it's easy to see if the value you've picked is performing better than the previous one or worse.

My scores:

bs=   I/O rate
---------------
4K    13.5 MB/s
64K   18.3 MB/s
8M    19.1 MB/s <--- winner!
10M   19.0 MB/s
20M   18.6 MB/s
100M  18.6 MB/s   

Note: To check what your disk cache/buffer size is, you can use sudo hdparm -i /dev/sda

Well, the naive approach (combine 2 lists into large one and sort) will be O(N*log(N)) complexity. On the other hand, if you implement the merge manually (i do not know about any ready code in python libs for this, but i'm no expert) the complexity will be O(N), which is clearly faster. The idea is described wery well in post by Barry Kelly.

UPDATED for clarification and example

examples: http://jsfiddle.net/pxfunc/5kpeJ/

Method 1. input event

In modern browsers use the input event. This event will fire when the user is typing into a text field, pasting, undoing, basically anytime the value changed from one value to another.

In jQuery do that like this

$('#someInput').bind('input', function() { 
    $(this).val() // get the current value of the input field.
});

starting with jQuery 1.7, replace bind with on:

$('#someInput').on('input', function() { 
    $(this).val() // get the current value of the input field.
});

Method 2. keyup event

For older browsers use the keyup event (this will fire once a key on the keyboard has been released, this event can give a sort of false positive because when "w" is released the input value is changed and the keyup event fires, but also when the "shift" key is released the keyup event fires but no change has been made to the input.). Also this method doesn't fire if the user right-clicks and pastes from the context menu:

$('#someInput').keyup(function() {
    $(this).val() // get the current value of the input field.
});

Method 3. Timer (setInterval or setTimeout)

To get around the limitations of keyup you can set a timer to periodically check the value of the input to determine a change in value. You can use setInterval or setTimeout to do this timer check. See the marked answer on this SO question: jQuery textbox change event or see the fiddle for a working example using focus and blur events to start and stop the timer for a specific input field

The following should work.

private void webBrowser1_DocumentCompleted(object sender, WebBrowserDocumentCompletedEventArgs e)
{
    //Check if page is fully loaded or not
    if (this.webBrowser1.ReadyState != WebBrowserReadyState.Complete)
        return;
    else
        //Action to be taken on page loading completion
}

RAII is usually better, but you can have easily the finally semantics in C++. Using a tiny amount of code.

Besides, the C++ Core Guidelines give finally.

Here is a link to the GSL Microsoft implementation and a link to the Martin Moene implementation

Bjarne Stroustrup multiple times said that everything that is in the GSL it meant to go in the standard eventually. So it should be a future-proof way to use finally.

You can easily implement yourself if you want though, continue reading.

In C++11 RAII and lambdas allows to make a general finally:

namespace detail { //adapt to your "private" namespace
template <typename F>
struct FinalAction {
    FinalAction(F f) : clean_{f} {}
   ~FinalAction() { if(enabled_) clean_(); }
    void disable() { enabled_ = false; };
  private:
    F clean_;
    bool enabled_{true}; }; }

template <typename F>
detail::FinalAction<F> finally(F f) {
    return detail::FinalAction<F>(f); }

example of use:

#include <iostream>
int main() {
    int* a = new int;
    auto delete_a = finally([a] { delete a; std::cout << "leaving the block, deleting a!\n"; });
    std::cout << "doing something ...\n"; }

the output will be:

doing something...
leaving the block, deleting a!

Personally I used this few times to ensure to close POSIX file descriptor in a C++ program.

Having a real class that manage resources and so avoids any kind of leaks is usually better, but this finally is useful in the cases where making a class sounds like an overkill.

Besides, I like it better than other languages finally because if used naturally you write the closing code nearby the opening code (in my example the new and delete) and destruction follows construction in LIFO order as usual in C++. The only downside is that you get an auto variable you don't really use and the lambda syntax make it a little noisy (in my example in the fourth line only the word finally and the {}-block on the right are meaningful, the rest is essentially noise).

Another example:

 [...]
 auto precision = std::cout.precision();
 auto set_precision_back = finally( [precision, &std::cout]() { std::cout << std::setprecision(precision); } );
 std::cout << std::setprecision(3);

The disable member is useful if the finally has to be called only in case of failure. For example, you have to copy an object in three different containers, you can setup the finally to undo each copy and disable after all copies are successful. Doing so, if the destruction cannot throw, you ensure the strong guarantee.

disable example:

//strong guarantee
void copy_to_all(BIGobj const& a) {
    first_.push_back(a);
    auto undo_first_push = finally([first_&] { first_.pop_back(); });

    second_.push_back(a);
    auto undo_second_push = finally([second_&] { second_.pop_back(); });

    third_.push_back(a);
    //no necessary, put just to make easier to add containers in the future
    auto undo_third_push = finally([third_&] { third_.pop_back(); });

    undo_first_push.disable();
    undo_second_push.disable();
    undo_third_push.disable(); }

If you cannot use C++11 you can still have finally, but the code becomes a bit more long winded. Just define a struct with only a constructor and destructor, the constructor take references to anything needed and the destructor does the actions you need. This is basically what the lambda does, done manually.

#include <iostream>
int main() {
    int* a = new int;

    struct Delete_a_t {
        Delete_a_t(int* p) : p_(p) {}
       ~Delete_a_t() { delete p_; std::cout << "leaving the block, deleting a!\n"; }
        int* p_;
    } delete_a(a);

    std::cout << "doing something ...\n"; }

Hopefully you can use C++11, this code is more to show how the "C++ does not support finally" has been nonsense since the very first weeks of C++, it was possible to write this kind of code even before C++ got its name.

This very second in time

ps -U $(whoami) -eom pid,pmem,pcpu,comm | head -n4

Continuously updating

watch -n 1 'ps -U $(whoami) -eom pid,pmem,pcpu,comm | head -n4'

I also added a few goodies here you might appreciate (or you might ignore)

-n 1 watch and update every second

-U $(whoami) To show only your processes. $(some command) evaluates now

| head -n4 To only show the header and 3 processes at a time bc often you just need high usage line items

${1-4} says my first argument $1 I want to default to 4, unless I provide it

If you are using a mac you may need to install watch first brew install watch

Alternatively you might use a function

psm(){
    watch -n 1 "ps -eom pid,pmem,pcpu,comm | head -n ${1-4}"
    # EXAMPLES: 
    # psm 
    # psm 10
}
