Look at SELECT INTO. This will create a new table for you, which can be temporary if you want by prefixing the table name with a pound sign (#).

For example, you can do:

SELECT * 
INTO #YourTempTable
FROM YourReportQuery

Interestingly virtually all answers revolve around XPath's function contains(), neglecting the fact it is case sensitive - contrary to the OP's ask.

If you need case insensitivity, that is achievable in XPath 1.0 (the version contemporary browsers support), though it's not pretty - by using the translate() function. It substitutes a source character to its desired form, by using a translation table.

Constructing a table of all upper case characters will effectively transform the node's text to its lower() form - allowing case-insensitive matching (here's just the prerogative):

[
  contains(
    translate(text(), 'ABCDEFGHIJKLMNOPQRSTUVWXYZ', 'abcdefghijklmnopqrstuvwxyz'),
    'my button'
  )
]
# will match a source text like "mY bUTTon"

The full Python call:

driver.find_elements_by_xpath("//*[contains(translate(text(), 'ABCDEFGHIJKLMNOPQRSTUVWXYZ?', 'abcdefghijklmnopqrstuvwxyz?'), 'my button')]")

Naturally this approach has its drawbacks - as given, it'll work only for Latin text; if you want to cover Unicode characters - you'll have to add them to the translation table. I've done that in the sample above - the last character is the Cyrillic symbol "?".

And if we lived in a world where browsers supported XPath 2.0 and up (, but not happening any time soon ??), we could having used the functions lower-case() (yet, not fully locale-aware), and matches (for regex searches, with the case-insensitive ('i') flag).

Only call time pass-by-reference is removed. So change:

call_user_func($func, &$this, &$client ...

To this:

call_user_func($func, $this, $client ...

&$this should never be needed after PHP4 anyway period.

If you absolutely need $client to be passed by reference, update the function ($func) signature instead (function func(&$client) {)

You cannot place the IsNull() until after the data is selected so you will place the IsNull() around the final value in the SELECT:

SELECT CLASS,
  IsNull([AZ], 0) as [AZ],
  IsNull([CA], 0) as [CA],
  IsNull([TX], 0) as [TX]
FROM #TEMP
PIVOT 
(
  SUM(DATA)
  FOR STATE IN ([AZ], [CA], [TX])
) AS PVT
ORDER BY CLASS

*** Start ***

@echo off

Set RegQry=HKLM\Hardware\Description\System\CentralProcessor\0

REG.exe Query %RegQry% > checkOS.txt

Find /i "x86" < CheckOS.txt > StringCheck.txt

If %ERRORLEVEL% == 0 (
    Echo "This is 32 Bit Operating system"
) ELSE (
    Echo "This is 64 Bit Operating System"
)

Whenever you have seen coding from open source community like Guava and from Google Developer (Android Library) they used this approach

List<String> strings = new ArrayList<String>();

because it's hide the implementation detail from user. You precisely

List<String> strings = new ArrayList<String>(); 

it's generic approach and this specialized approach

ArrayList<String> strings = new ArrayList<String>();

For Reference: Effective Java 2nd Edition: Item 52: Refer to objects by their interfaces

Every time the randint() method is called inside the for loop a different seed is set and a sequence is generated according to the time. But as for loop runs fast in your computer in a small time the seed is almost same and a very similar sequence is generated to the past one due to the time. So setting the seed outside the randint() method is enough.

package main

import (
    "bytes"
    "fmt"
    "math/rand"
    "time"
)

var r = rand.New(rand.NewSource(time.Now().UTC().UnixNano()))
func main() {
    fmt.Println(randomString(10))
}

func randomString(l int) string {

    var result bytes.Buffer
    var temp string
    for i := 0; i < l; {
        if string(randInt(65, 90)) != temp {
            temp = string(randInt(65, 90))
            result.WriteString(temp)
            i++
        }
    }
    return result.String()
}

func randInt(min int, max int) int {
    return min + r.Intn(max-min)
}

Copy the diff file to the root of your repository, and then do:

git apply yourcoworkers.diff

More information about the apply command is available on its man page.

By the way: A better way to exchange whole commits by file is the combination of the commands git format-patch on the sender and then git am on the receiver, because it also transfers the authorship info and the commit message.

If the patch application fails and if the commits the diff was generated from are actually in your repo, you can use the -3 option of apply that tries to merge in the changes.

It also works with Unix pipe as follows:

git diff d892531 815a3b5 | git apply

The best and easy way to get the activity context is putting .this after the name of the Activity. For example: If your Activity's name is SecondActivity, its context will be SecondActivity.this

Update your remote if you still haven't done so:

$ git remote update
$ git branch -r

I had a similar issue and based on above suggestions I first added "super.setIntegerProperty("loadUrlTimeoutValue", 70000);" but that did not help. So I tried Project -> Clean, that worked and I can launch the app now !

Add action to your form.

Updated for Bootstrap 3 and 4

Bootstrap 3 and Bootstrap 4 docs refer two events you can use.

hide.bs.modal: This event is fired immediately when the hide instance method has been called.
hidden.bs.modal: This event is fired when the modal has finished being hidden from the user (will wait for CSS transitions to complete).

And provide an example on how to use them:

$('#myModal').on('hidden.bs.modal', function () {
  // do something…
})

Legacy Bootstrap 2.3.2 answer

Bootstrap's documentation refers two events you can use.

hide: This event is fired immediately when the hide instance method has been called.
hidden: This event is fired when the modal has finished being hidden from the user (will wait for css transitions to complete).

And provides an example on how to use them:

$('#myModal').on('hidden', function () {
    // do something…
})

It looks like you're using python 3.x. In python3, filter, map, zip, etc return an object which is iterable, but not a list. In other words,

filter(func,data) #python 2.x

is equivalent to:

list(filter(func,data)) #python 3.x

I think it was changed because you (often) want to do the filtering in a lazy sense -- You don't need to consume all of the memory to create a list up front, as long as the iterator returns the same thing a list would during iteration.

If you're familiar with list comprehensions and generator expressions, the above filter is now (almost) equivalent to the following in python3.x:

( x for x in data if func(x) ) 

As opposed to:

[ x for x in data if func(x) ]

in python 2.x

private void TextBox1_KeyUp(object sender, KeyEventArgs e)
{
     if (e.KeyCode == Keys.Enter)
     {
         MessageBox.Show("Enter pressed");
     }
 }

Worked for me.

Use CHAR:

=Char(34)&"This is in quotes"&Char(34)

Should evaluate to:

"This is in quotes"

Here are a few things you need to do:

1-Download the library if you haven't already done that.

2- Import into Eclipse.

3- Set you project to use the library: Project-> Properties -> Android -> Scroll down to Library section, click Add... and select viewpagerindicator.

4- Now you should be able to import com.viewpagerindicator.TitlePageIndicator.

Now about implementing this without using fragments:

In the sample that comes with viewpagerindicatior, you can see that the library is being used with a ViewPager which has a FragmentPagerAdapter.

But in fact the library itself is Fragment independant. It just needs a ViewPager. So just use a PagerAdapter instead of a FragmentPagerAdapter and you're good to go.

I encountered with same error and resolved it with redeployment after removing deployment.

The Lazy<T> version:

public sealed class Singleton
{
    private static readonly Lazy<Singleton> lazy
        = new Lazy<Singleton>(() => new Singleton());

    public static Singleton Instance

    private Singleton() { }
}

Requires .NET 4 and C# 6.0 (VS2015) or newer.

For make a list, simply do that

colors=(red orange white "light gray")

Technically is an array, but - of course - it has all list features.
Even python list are implemented with array

A cause can be invalid encoding in the URL request. Such as % being passed un-encoded.

This example let may highlight the differ between "at" and "asterix" while we using them. I declared two arrays "fruits" and "vegetables"

fruits=(apple pear plumm peach melon)            
vegetables=(carrot tomato cucumber potatoe onion)

printf "Fruits:\t%s\n" "${fruits[*]}"            
printf "Fruits:\t%s\n" "${fruits[@]}"            
echo + --------------------------------------------- +      
printf "Vegetables:\t%s\n" "${vegetables[*]}"    
printf "Vegetables:\t%s\n" "${vegetables[@]}"    

See the following result the code above:

Fruits: apple pear plumm peach melon
Fruits: apple
Fruits: pear
Fruits: plumm
Fruits: peach
Fruits: melon
+ --------------------------------------------- +
Vegetables: carrot tomato cucumber potatoe onion
Vegetables: carrot
Vegetables: tomato
Vegetables: cucumber
Vegetables: potatoe
Vegetables: onion

<textarea name="hide" style="display:none;"></textarea>

This sets the css display property to none, which prevents the browser from rendering the textarea.

The filesystem size can be different from the patition size. To repair you need to do this

df -h

see what is the name of the partition say /dev/sda3

resize2fs /dev/sda3

If you want to have more flexibility with filenames and compression options, you can use:

find /my/path/ -type f -name "*.sql" -o -name "*.log" -exec \
tar -P --transform='s@/my/path/@@g' -cf - {} + | \
pigz -9 -p 4 > myarchive.tar.gz

Step 1: find

find /my/path/ -type f -name "*.sql" -o -name "*.log" -exec

This command will look for the files you want to archive, in this case /my/path/*.sql and /my/path/*.log. Add as many -o -name "pattern" as you want.

-exec will execute the next command using the results of find: tar

Step 2: tar

tar -P --transform='s@/my/path/@@g' -cf - {} +

--transform is a simple string replacement parameter. It will strip the path of the files from the archive so the tarball's root becomes the current directory when extracting. Note that you can't use -C option to change directory as you'll lose benefits of find: all files of the directory would be included.

-P tells tar to use absolute paths, so it doesn't trigger the warning "Removing leading `/' from member names". Leading '/' with be removed by --transform anyway.

-cf - tells tar to use the tarball name we'll specify later

{} + uses everyfiles that find found previously

Step 3: pigz

pigz -9 -p 4

Use as many parameters as you want. In this case -9 is the compression level and -p 4 is the number of cores dedicated to compression. If you run this on a heavy loaded webserver, you probably don't want to use all available cores.

Step 4: archive name

> myarchive.tar.gz

Finally.

The formula provided by Blake doesn't seem to work for me. For past dates it returns due in xx days and for future dates, it returns overdue. Also, it will only return 15 days overdue, when it could actually be 30, 60 90+.

I created this, which seems to work and provides 'Due in xx days', 'Overdue xx days' and 'Due Today'.

=IF(ISBLANK(O10),"",IF(DAYS(TODAY(),O10)<0,CONCATENATE("Due in ",-DAYS(TODAY(),O10)," Days"),IF(DAYS(TODAY(),O10)>0,CONCATENATE("Overdue ",DAYS(TODAY(),O10)," Days"),"Due Today")))

This is the simple one to perform substring in Go

package main

import "fmt"

var p = fmt.Println

func main() {

  value := "address;bar"

  // Take substring from index 2 to length of string
  substring := value[2:len(value)]
  p(substring)

}

Did you check the string concatenation function? Something like:

update table_c set column_a = column_b || column_c 

should work. More here

I tried all the different things mentioned here to get the index of the . character in a filename that ends with .[0-9][0-9]*, e.g. srcfile.1, srcfile.12, etc. Nothing worked. Finally, the following worked: int dotIndex = inputfilename.lastIndexOf(".");

Weird! This is with java -version:

openjdk version "1.8.0_131"
OpenJDK Runtime Environment (build 1.8.0_131-8u131-b11-0ubuntu1.16.10.2-b11)
OpenJDK 64-Bit Server VM (build 25.131-b11, mixed mode)

Also, the official Java doc page for regex (from which there is a quote in one of the answers above) does not seem to specify how to look for the . character. Because \., \\., and [.] did not work for me, and I don't see any other options specified apart from these.

You can use the entry set and iterate over the entries which allows you to access both, key and value, directly.

for (Entry<String, ArrayList<String>> entry : test1.entrySet() {
     System.out.println(entry.getKey() + "/" + entry.getValue());
}

I tried this but get only returns string

Why do you think so? The method get returns the type E for which the generic type parameter was chosen, in your case ArrayList<String>.

Angular has an orderBy filter that can be used like this:

<select ng-model="selected" ng-options="f.name for f in friends | orderBy:'name'"></select>

See this fiddle for an example.

It's worth noting that if track by is being used it needs to appear after the orderBy filter, like this:

<select ng-model="selected" ng-options="f.name for f in friends | orderBy:'name' track by f.id"></select>

This should work just like you asked!

I don't have enough reputation to add in comments, so I just write some of my findings of this annoying TypeError here:

Basically, I think it's a bug in the json.dump() function in Python 2 only - It can't dump a Python (dictionary / list) data containing non-ASCII characters, even you open the file with the encoding = 'utf-8' parameter. (i.e. No matter what you do). But, json.dumps() works on both Python 2 and 3.

To illustrate this, following up phihag's answer: the code in his answer breaks in Python 2 with exception TypeError: must be unicode, not str, if data contains non-ASCII characters. (Python 2.7.6, Debian):

import json
data = {u'\u0430\u0431\u0432\u0433\u0434': 1} #{u'?????': 1}
with open('data.txt', 'w') as outfile:
    json.dump(data, outfile)

It however works fine in Python 3.

You can modify various VM properties by adding the following configuration (see the Vagrant docs for a bit more info):

  # Configure VM Ram usage
  config.vm.customize [
                        "modifyvm", :id,
                        "--name", "Test_Environment",
                        "--memory", "1024"
                      ]

You can obtain the properties that you want to change from the documents for VirtualBox command-line options:

• http://www.virtualbox.org/manual/ch08.html#vboxmanage-modifyvm

The vagrant documentation has the section on how to change IP address:

Vagrant::Config.run do |config|
  config.vm.network :hostonly, "192.168.50.4"
end

Also you can restructure the configuration like this, ending is do with end without nesting it. This is simpler.

config.vm.define :web do |web_config|
    web_config.vm.box = "lucid32"
    web_config.vm.forward_port 80, 8080
end
web_config.vm.provision :puppet do |puppet|
    puppet.manifests_path = "manifests"
    puppet.manifest_file = "lucid32.pp"
end

They refer to the same element, the difference is that when you say document.body you are passing the element directly to jQuery. Alternatively, when you pass the string 'body', the jQuery selector engine has to interpret the string to figure out what element(s) it refers to.

In practice either will get the job done.

If you are interested, there is more information in the documentation for the jQuery function.

Use .loc for label based indexing:

df.loc[df.A==0, 'B'] = np.nan

The df.A==0 expression creates a boolean series that indexes the rows, 'B' selects the column. You can also use this to transform a subset of a column, e.g.:

df.loc[df.A==0, 'B'] = df.loc[df.A==0, 'B'] / 2

I don't know enough about pandas internals to know exactly why that works, but the basic issue is that sometimes indexing into a DataFrame returns a copy of the result, and sometimes it returns a view on the original object. According to documentation here, this behavior depends on the underlying numpy behavior. I've found that accessing everything in one operation (rather than [one][two]) is more likely to work for setting.

Official document of Crypto++ AES is a good start. And from my archive, a basic implementation of AES is as follows:

Please refer here with more explanation, I recommend you first understand the algorithm and then try to understand each line step by step.

#include <iostream>
#include <iomanip>

#include "modes.h"
#include "aes.h"
#include "filters.h"

int main(int argc, char* argv[]) {

    //Key and IV setup
    //AES encryption uses a secret key of a variable length (128-bit, 196-bit or 256-   
    //bit). This key is secretly exchanged between two parties before communication   
    //begins. DEFAULT_KEYLENGTH= 16 bytes
    CryptoPP::byte key[ CryptoPP::AES::DEFAULT_KEYLENGTH ], iv[ CryptoPP::AES::BLOCKSIZE ];
    memset( key, 0x00, CryptoPP::AES::DEFAULT_KEYLENGTH );
    memset( iv, 0x00, CryptoPP::AES::BLOCKSIZE );

    //
    // String and Sink setup
    //
    std::string plaintext = "Now is the time for all good men to come to the aide...";
    std::string ciphertext;
    std::string decryptedtext;

    //
    // Dump Plain Text
    //
    std::cout << "Plain Text (" << plaintext.size() << " bytes)" << std::endl;
    std::cout << plaintext;
    std::cout << std::endl << std::endl;

    //
    // Create Cipher Text
    //
    CryptoPP::AES::Encryption aesEncryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Encryption cbcEncryption( aesEncryption, iv );

    CryptoPP::StreamTransformationFilter stfEncryptor(cbcEncryption, new CryptoPP::StringSink( ciphertext ) );
    stfEncryptor.Put( reinterpret_cast<const unsigned char*>( plaintext.c_str() ), plaintext.length() );
    stfEncryptor.MessageEnd();

    //
    // Dump Cipher Text
    //
    std::cout << "Cipher Text (" << ciphertext.size() << " bytes)" << std::endl;

    for( int i = 0; i < ciphertext.size(); i++ ) {

        std::cout << "0x" << std::hex << (0xFF & static_cast<CryptoPP::byte>(ciphertext[i])) << " ";
    }

    std::cout << std::endl << std::endl;

    //
    // Decrypt
    //
    CryptoPP::AES::Decryption aesDecryption(key, CryptoPP::AES::DEFAULT_KEYLENGTH);
    CryptoPP::CBC_Mode_ExternalCipher::Decryption cbcDecryption( aesDecryption, iv );

    CryptoPP::StreamTransformationFilter stfDecryptor(cbcDecryption, new CryptoPP::StringSink( decryptedtext ) );
    stfDecryptor.Put( reinterpret_cast<const unsigned char*>( ciphertext.c_str() ), ciphertext.size() );
    stfDecryptor.MessageEnd();

    //
    // Dump Decrypted Text
    //
    std::cout << "Decrypted Text: " << std::endl;
    std::cout << decryptedtext;
    std::cout << std::endl << std::endl;

    return 0;
}

For installation details :

• How do I install Crypto++ in Visual Studio 2010 Windows 7?
• *nix environment
• For Ubuntu I did:

sudo apt-get install libcrypto++-dev libcrypto++-doc libcrypto++-utils

iPhone:

Mozilla/5.0 (iPhone; CPU iPhone OS 6_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A5376e Safari/8536.25

iPad:

Mozilla/5.0 (iPad; CPU OS 6_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A5376e Safari/8536.25

Connect to the database, then list the tables:

\c liferay
\dt

That's how I do it anyway.

You can combine those two commands onto a single line, if you prefer:

\c liferay \dt

Now in iOS 6 and above, you can use:

[[Picker presentingViewController] dismissViewControllerAnimated:YES completion:nil];

Instead of:

[[Picker parentViewControl] dismissModalViewControllerAnimated:YES];

...And you can use:

[self presentViewController:picker animated:YES completion:nil];

Instead of

[self presentModalViewController:picker animated:YES];    

You can use the -B and -A to print lines before and after the match.

grep -i -B 10 'error' data

Will print the 10 lines before the match, including the matching line itself.

An alternative solution to changing the font size is to change the padding. When Python saves your PNG, you can change the layout using the dialogue box that opens. The spacing between the axes, padding if you like can be altered at this stage.

My best effort so far, supporting different backends:

from platform import system
def plt_maximize():
    # See discussion: https://stackoverflow.com/questions/12439588/how-to-maximize-a-plt-show-window-using-python
    backend = plt.get_backend()
    cfm = plt.get_current_fig_manager()
    if backend == "wxAgg":
        cfm.frame.Maximize(True)
    elif backend == "TkAgg":
        if system() == "win32":
            cfm.window.state('zoomed')  # This is windows only
        else:
            cfm.resize(*cfm.window.maxsize())
    elif backend == 'QT4Agg':
        cfm.window.showMaximized()
    elif callable(getattr(cfm, "full_screen_toggle", None)):
        if not getattr(cfm, "flag_is_max", None):
            cfm.full_screen_toggle()
            cfm.flag_is_max = True
    else:
        raise RuntimeError("plt_maximize() is not implemented for current backend:", backend)

Use:

mysqldump --extended-insert=FALSE 

Be aware that multiple inserts will be slower than one big insert.

SELECT * 
FROM reservations 
WHERE arrival >= '2012-01-01'
AND arrival < '2013-01-01'
   ;

BTW if the distribution of values indicates that an index scan will not be the worth (for example if all the values are in 2012), the optimiser could still choose a full table scan. YMMV. Explain is your friend.

Ask this questions yourself? And you will decide your DB selection.

1. Do you need master-master? Then CouchDB. Mainly CouchDB supports master-master replication which anticipates nodes being disconnected for long periods of time. MongoDB would not do well in that environment.
2. Do you need MAXIMUM R/W throughput? Then MongoDB
3. Do you need ultimate single-server durability because you are only going to have a single DB server? Then CouchDB.
4. Are you storing a MASSIVE data set that needs sharding while maintaining insane throughput? Then MongoDB.
5. Do you need strong consistency of data? Then MongoDB.
6. Do you need high availability of database? Then CouchDB.
7. Are you hoping multi databases and multi tables/ collections? Then MongoDB
8. You have a mobile app offline users and want to sync their activity data to a server? Then you need CouchDB.
9. Do you need large variety of querying engine? Then MongoDB
10. Do you need large community to be using DB? Then MongoDB

Don't know if you solved the problem but if anyone has this problem in future.

The answer, u, (and many others) is in $ vimtutor.

This is working for me. Which version of Flask are you using?

from flask import jsonify

...

@app.route('/test/json')
def test_json():
    list = [
            {'a': 1, 'b': 2},
            {'a': 5, 'b': 10}
           ]
    return jsonify(results = list)

This is an alternate implementation using function instead of class. Inspired by @Andrew Wilkins above.

Because wait is more accurate than sleep ( it takes function runtime into account ):

import threading

PING_ON = threading.Event()

def ping():
  while not PING_ON.wait(1):
    print("my thread %s" % str(threading.current_thread().ident))

t = threading.Thread(target=ping)
t.start()

sleep(5)
PING_ON.set()

I found this topic while searching for run script for startup and shutdown Windows 10. Those answers above didn't working. For me on windows 10 worked when I put scripts to task scheduler. How to do this: press window key and write Task scheduler, open it, then on the right is Add task... button. Here you can add scripts. PS: I found action for startup and logout user, there is not for shutdown.

You can make use of bitwise AND operator &. Let's see below:

x = [1, 2, 3, 4, 5, 6, 7]
y = [i for i in x if i&1]
>>> 
[1, 3, 5, 7]

Bitwise AND operator is used with 1, and the reason it works because, odd number when written in binary must have its first digit as 1. Let's check

23 = 1 * (2**4) + 0 * (2**3) + 1 * (2**2) + 1 * (2**1) + 1 * (2**0) = 10111
14 = 1 * (2**3) + 1 * (2**2) + 1 * (2**1) + 0 * (2**0) = 1110

AND operation with 1 will only return 1 (1 in binary will also have last digit 1), iff the value is odd.

Check the Python Bitwise Operator page for more.

P.S: You can tactically use this method if you want to select odd and even columns in a dataframe. Let's say x and y coordinates of facial key-points are given as columns x1, y1, x2, etc... To normalize the x and y coordinates with width and height values of each image you can simply perform

for i in range(df.shape[1]):
    if i&1:
        df.iloc[:, i] /= heights
    else:
        df.iloc[:, i] /= widths

This is not exactly related to the question but for data scientists and computer vision engineers this method could be useful.

Cheers!

If your values are non-null strings or numbers, you can use an object as a dictionary:

var map = {}, result = [], i;
for (i = 0; i < array1.length; ++i) {
    map[array1[i]] = 1;
}

for (i = 0; i < array2.length; ++i) {
    if (map[array2[i]] === 1) {
        result.push(array2[i]);

        // avoid returning a value twice if it appears twice in array 2
        map[array2[i]] = 0;
    }
}

return result;

Below JS function you can use to filter the row based on some specified columns see searchColumn array. It is taken from w3 school and little bit customised to search and filter on the given list of column.

Short answer: Yes. Use Python's urllib to pull the historical data pages for the stocks you want. Go with Yahoo! Finance; Google is both less reliable, has less data coverage, and is more restrictive in how you can use it once you have it. Also, I believe Google specifically prohibits you from scraping the data in their ToS.

Longer answer: This is the script I use to pull all the historical data on a particular company. It pulls the historical data page for a particular ticker symbol, then saves it to a csv file named by that symbol. You'll have to provide your own list of ticker symbols that you want to pull.

import urllib

base_url = "http://ichart.finance.yahoo.com/table.csv?s="
def make_url(ticker_symbol):
    return base_url + ticker_symbol

output_path = "C:/path/to/output/directory"
def make_filename(ticker_symbol, directory="S&P"):
    return output_path + "/" + directory + "/" + ticker_symbol + ".csv"

def pull_historical_data(ticker_symbol, directory="S&P"):
    try:
        urllib.urlretrieve(make_url(ticker_symbol), make_filename(ticker_symbol, directory))
    except urllib.ContentTooShortError as e:
        outfile = open(make_filename(ticker_symbol, directory), "w")
        outfile.write(e.content)
        outfile.close()

Give your radiobutton a custom style:

<style name="MyRadioButtonStyle" parent="@android:style/Widget.CompoundButton.RadioButton">
    <item name="android:button">@drawable/custom_btn_radio</item>

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true" android:state_window_focused="false"
          android:drawable="@drawable/btn_radio_on" />
    <item android:state_checked="false" android:state_window_focused="false"
          android:drawable="@drawable/btn_radio_off" />

    <item android:state_checked="true" android:state_pressed="true"
          android:drawable="@drawable/btn_radio_on_pressed" />
    <item android:state_checked="false" android:state_pressed="true"

I was facing the same issue. I tried both $http_my_custom_header and $sent_http_my_custom_header but it did not work for me.

Although solved this issue by using $upstream_http_my_custom_header.

If someone is facing issue using texttocolumns function in UFT. Please try using below function.

myxl.Workbooks.Open myexcel.xls
myxl.Application.Visible = false `enter code here`
set mysheet = myxl.ActiveWorkbook.Worksheets(1)
Set objRange = myxl.Range("A1").EntireColumn
Set objRange2 = mysheet.Range("A1")
objRange.TextToColumns objRange2,1,1, , , , true

Here we are using coma(,) as delimiter.

While AngularJS allows you to get a hand on a click event (and thus a target of it) with the following syntax (note the $event argument to the setMaster function; documentation here: http://docs.angularjs.org/api/ng.directive:ngClick):

function AdminController($scope) {    
  $scope.setMaster = function(obj, $event){
    console.log($event.target);
  }
}

this is not very angular-way of solving this problem. With AngularJS the focus is on the model manipulation. One would mutate a model and let AngularJS figure out rendering.

The AngularJS-way of solving this problem (without using jQuery and without the need to pass the $event argument) would be:

<div ng-controller="AdminController">
    <ul class="list-holder">
        <li ng-repeat="section in sections" ng-class="{active : isSelected(section)}">
            <a ng-click="setMaster(section)">{{section.name}}</a>
        </li>
    </ul>
    <hr>
    {{selected | json}}
</div>

where methods in the controller would look like this:

$scope.setMaster = function(section) {
    $scope.selected = section;
}

$scope.isSelected = function(section) {
    return $scope.selected === section;
}

Here is the complete jsFiddle: http://jsfiddle.net/pkozlowski_opensource/WXJ3p/15/

Try to use this.

        for (int i = 0; i < chBoxListTables.Items.Count; i++)
        {
            if (chBoxListTables.Items[i].Selected)
            {
                string str = chBoxListTables.Items[i].Text;
                MessageBox.Show(str);

                var itemValue = chBoxListTables.Items[i].Value;
            }
        }

The "V" should be in CAPS in Value.

Here is another code example used in WinForm app and runs properly.

        var chBoxList= new CheckedListBox();
        chBoxList.Items.Add(new ListItem("One", "1"));
        chBoxList.Items.Add(new ListItem("Two", "2"));
        chBoxList.SetItemChecked(1, true);

        var checkedItems = chBoxList.CheckedItems;
        var chkText = ((ListItem)checkedItems[0]).Text;
        var chkValue = ((ListItem)checkedItems[0]).Value;
        MessageBox.Show(chkText);
        MessageBox.Show(chkValue);

json_decode() will return an object or array if second value it's true:

$json = '{"countryId":"84","productId":"1","status":"0","opId":"134"}';
$json = json_decode($json, true);
echo $json['countryId'];
echo $json['productId'];
echo $json['status'];
echo $json['opId'];

As documented under CREATE TABLE Syntax:

Note
The older TYPE option was synonymous with ENGINE. TYPE was deprecated in MySQL 4.0 and removed in MySQL 5.5. When upgrading to MySQL 5.5 or later, you must convert existing applications that rely on TYPE to use ENGINE instead.

Therefore, you want:

CREATE TABLE dave_bannedwords(
  id   INT(11)     NOT NULL AUTO_INCREMENT,
  word VARCHAR(60) NOT NULL DEFAULT '',
  PRIMARY KEY (id),
  KEY id(id) -- this is superfluous in the presence of your PK, ergo unnecessary
) ENGINE = MyISAM ;

Yet another base R option could be:

lengths(lapply(q.data$string, grepRaw, pattern = "a", all = TRUE, fixed = TRUE))

[1] 2 1 0

After setting Java Path, if you are not able to open your eclipse do below steps:

1. Go to your Eclipse Folder where you have extracted your eclipse.

2. Open Eclipse file in notepad (by default it will open on notepad)

Enter two lines

-vm
C:/Program Files/Java/jdk-11.0.2/bin/javaw.exe

jdk-11.0.2 ,It should be your Java Version, which you will get by the above location.

There is no default database for user. There is default database for current session.

You can get it using DATABASE() function -

SELECT DATABASE();

And you can set it using USE statement -

USE database1;

You should set it manually - USE db_name, or in the connection string.

false != 'false'

For good measures, put the result of validate into a variable to avoid double validation and use that in the IF statement. Like this:

var result = ValidateForm();
if(result == false) {
...
}

I had this error and other related ones, when I imported at 16 GB SQL file. For me, editing my.ini and setting the following (based on several different posts) in the [mysqld] section:

max_allowed_packet      = 110M
innodb_buffer_pool_size=511M
innodb_log_file_size=500M
innodb_log_buffer_size = 800M
net_read_timeout        = 600
net_write_timeout       = 600

If you are running under Windows, go to the control panel, services, and look at the details for MySQL and you will see where my.ini is. Then after you edit and save my.ini, restart the mysql service (or restart the computer).

If you are using HeidiSQL, you can also set some or all of these using that.

You can use a deadlock graph and gather the information you require from the log file.

The only other way I could suggest is digging through the information by using EXEC SP_LOCK (Soon to be deprecated), EXEC SP_WHO2 or the sys.dm_tran_locks table.

SELECT  L.request_session_id AS SPID, 
    DB_NAME(L.resource_database_id) AS DatabaseName,

    L.resource_type AS LockedResource, 
    L.request_mode AS LockType,
    ST.text AS SqlStatementText,        
    ES.login_name AS LoginName,
    ES.host_name AS HostName,
    TST.is_user_transaction as IsUserTransaction,

I hope this will give you the idea.

Please note that MVC 3 onwards the persistence behavior of TempData has changed, now the value in TempData is persisted until it is read, and not just for the next request.

The value of TempData persists until it is read or until the session times out. Persisting TempData in this way enables scenarios such as redirection, because the values in TempData are available beyond a single request. https://msdn.microsoft.com/en-in/library/dd394711%28v=vs.100%29.aspx

Some times there are problems with funtion/features that do not interact with the DOM

try to change the value sharply and then assign the $scope

document.getElementById ("textWidget") value = "<NewVal>";
$scope.widget.title = "<NewVal>";

I came across this question when I was trying similar things.

Try this code

public static String pathRoot = "/sdcard/system/temp/";
public static String readFromFile(Context contect, String nameFile) {
    String aBuffer = "";
    try {
        File myFile = new File(pathRoot + nameFile);
        FileInputStream fIn = new FileInputStream(myFile);
        BufferedReader myReader = new BufferedReader(new InputStreamReader(fIn));
        String aDataRow = "";
        while ((aDataRow = myReader.readLine()) != null) {
            aBuffer += aDataRow;
        }
        myReader.close();
    } catch (FileNotFoundException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return aBuffer;
}

If you need to print the number you can use printf

System.out.printf("%02d", num);

You can use

String.format("%02d", num);

or

(num < 10 ? "0" : "") + num;

or

(""+(100+num)).substring(1);

Just in case you actually mean 'discard changes' whenever you use 'git stash' (and don't really use git stash to stash it temporarily), in that case you can use

git checkout -- <file>

Note that git stash is just a quicker and simple alternative to branching and doing stuff.

ng-bind has one-way data binding ($scope --> view). It has a shortcut {{ val }} which displays the scope value $scope.val inserted into html where val is a variable name.

ng-model is intended to be put inside of form elements and has two-way data binding ($scope --> view and view --> $scope) e.g. <input ng-model="val"/>.

Encoding.Unicode is Microsoft's misleading name for UTF-16 (a double-wide encoding, used in the Windows world for historical reasons but not used by anyone else). http://msdn.microsoft.com/en-us/library/system.text.encoding.unicode.aspx

If you inspect your bytes array, you'll see that every second byte is 0x00 (because of the double-wide encoding).

You should be using Encoding.UTF8.GetBytes instead.

But also, you will see different results depending on whether or not you consider the terminating '\0' byte to be part of the data you're hashing. Hashing the two bytes "Hi" will give a different result from hashing the three bytes "Hi". You'll have to decide which you want to do. (Presumably you want to do whichever one your friend's PHP code is doing.)

For ASCII text, Encoding.UTF8 will definitely be suitable. If you're aiming for perfect compatibility with your friend's code, even on non-ASCII inputs, you'd better try a few test cases with non-ASCII characters such as é and ? and see whether your results still match up. If not, you'll have to figure out what encoding your friend is really using; it might be one of the 8-bit "code pages" that used to be popular before the invention of Unicode. (Again, I think Windows is the main reason that anyone still needs to worry about "code pages".)

I wrote this program to do the math for you. Just enter in the summary statistics. No need to provide an array:

One-Sample Z-Test for a Population Proportion:

To do this for mean rather than proportion, change the formula for z accordingly

EDIT:
Here is the content from the link:

import scipy.stats as stats
import math

def one_sample_ztest_pop_proportion(tail, p, pbar, n, alpha):
    #Calculate test stat

    sigma = math.sqrt((p*(1-p))/(n))
    z = round((pbar - p) / sigma, 2)

    if tail == 'lower':
        pval = round(stats.norm(p, sigma).cdf(pbar),4)
        print("Results for a lower tailed z-test: ")


    elif tail == 'upper':
        pval = round(1 - stats.norm(p, sigma).cdf(pbar),4)
        print("Results for an upper tailed z-test: ")


    elif tail == 'two':
        pval = round(stats.norm(p, sigma).cdf(pbar)*2,4)
        print("Results for a two tailed z-test: ")


    #Print test results
    print("Test statistic = {}".format(z))   
    print("P-value = {}".format(pval))
    print("Confidence = {}".format(alpha))

    #Compare p-value to confidence level
    if pval <= alpha:
        print("{} <=  {}. Reject the null hypothesis.".format(pval, alpha))
    else:
        print("{} > {}. Do not reject the null hypothesis.".format(pval, alpha))


#one_sample_ztest_pop_proportion('upper', .20, .25, 400, .05)

#one_sample_ztest_pop_proportion('two', .64, .52, 100, .05)

Sure!

#file  -- test.py --
myvar = 42
def test_func():
    print("Hello!")

Now, this file ("test.py") is in python terminology a "module". We can import it (as long as it can be found in our PYTHONPATH) Note that the current directory is always in PYTHONPATH, so if use_test is being run from the same directory where test.py lives, you're all set:

#file -- use_test.py --
import test
test.test_func()  #prints "Hello!"
print (test.myvar)  #prints 42

from test import test_func #Only import the function directly into current namespace
test_func() #prints "Hello"
print (myvar)     #Exception (NameError)

from test import *
test_func() #prints "Hello"
print(myvar)      #prints 42

There's a lot more you can do than just that through the use of special __init__.py files which allow you to treat multiple files as a single module), but this answers your question and I suppose we'll leave the rest for another time.

I think you are very confused about what is occurring.

In Python, everything is an object:

• [] (a list) is an object
• 'abcde' (a string) is an object
• 1 (an integer) is an object
• MyClass() (an instance) is an object
• MyClass (a class) is also an object
• list (a type--much like a class) is also an object

They are all "values" in the sense that they are a thing and not a name which refers to a thing. (Variables are names which refer to values.) A value is not something different from an object in Python.

When you call a class object (like MyClass() or list()), it returns an instance of that class. (list is really a type and not a class, but I am simplifying a bit here.)

When you print an object (i.e. get a string representation of an object), that object's __str__ or __repr__ magic method is called and the returned value printed.

For example:

>>> class MyClass(object):
...     def __str__(self):
...             return "MyClass([])"
...     def __repr__(self):
...             return "I am an instance of MyClass at address "+hex(id(self))
... 
>>> m = MyClass()
>>> print m
MyClass([])
>>> m
I am an instance of MyClass at address 0x108ed5a10
>>> 

So what you are asking for, "I need that MyClass return a list, like list(), not the instance info," does not make any sense. list() returns a list instance. MyClass() returns a MyClass instance. If you want a list instance, just get a list instance. If the issue instead is what do these objects look like when you print them or look at them in the console, then create a __str__ and __repr__ method which represents them as you want them to be represented.

Update for new question about equality

Once again, __str__ and __repr__ are only for printing, and do not affect the object in any other way. Just because two objects have the same __repr__ value does not mean they are equal!

MyClass() != MyClass() because your class does not define how these would be equal, so it falls back to the default behavior (of the object type), which is that objects are only equal to themselves:

>>> m = MyClass()
>>> m1 = m
>>> m2 = m
>>> m1 == m2
True
>>> m3 = MyClass()
>>> m1 == m3
False

If you want to change this, use one of the comparison magic methods

For example, you can have an object that is equal to everything:

>>> class MyClass(object):
...     def __eq__(self, other):
...             return True
... 
>>> m1 = MyClass()
>>> m2 = MyClass()
>>> m1 == m2
True
>>> m1 == m1
True
>>> m1 == 1
True
>>> m1 == None
True
>>> m1 == []
True

I think you should do two things:

1. Take a look at this guide to magic method use in Python.

2. Justify why you are not subclassing list if what you want is very list-like. If subclassing is not appropriate, you can delegate to a wrapped list instance instead:

   class MyClass(object):
       def __init__(self):
           self._list = []
       def __getattr__(self, name):
           return getattr(self._list, name)
   
       # __repr__ and __str__ methods are automatically created
       # for every class, so if we want to delegate these we must
       # do so explicitly
       def __repr__(self):
           return "MyClass(%s)" % repr(self._list)
       def __str__(self):
           return "MyClass(%s)" % str(self._list)
   

   This will now act like a list without being a list (i.e., without subclassing list).

   >>> c = MyClass()
   >>> c.append(1)
   >>> c
   MyClass([1])
   

Executing Linq queries can generate extra threads. When I try to execute code that uses Linq query collection in the immediate window it often refuses to run because not enough threads are available to the debugger.

As others have said, for threads to exit when they are finished is perfectly normal.

a one-liner: ' '.join(sub[:1].upper() + sub[1:] for sub in text.split(' '))

For Nginx, the only thing that worked for me was adding this header:

add_header 'Access-Control-Allow-Headers' 'Authorization,Content-Type,Accept,Origin,User-Agent,DNT,Cache-Control,X-Mx-ReqToken,Keep-Alive,X-Requested-With,If-Modified-Since';

Along with the Access-Control-Allow-Origin header:

add_header 'Access-Control-Allow-Origin' '*';

Then reloaded the nginx config and it worked great. Credit https://gist.github.com/algal/5480916.

for i in `seq 1 20`; do curl http://url; done

Or if you want to get timing information back, use ab:

ab -n 20 http://url/

You edit an element's value by editing it's .value property.

document.getElementById('DATE').value = 'New Value';

I worked on the code given earlier by Eitan-T and reworked to output to CSV file. Found the results in earlier code weren't always giving correct values as well so i've improved it.

Comments with REM

A REM can remark a complete line, also a multiline caret at the line end, if it's not the end of the first token.

REM This is a comment, the caret is ignored^
echo This line is printed

REM This_is_a_comment_the_caret_appends_the_next_line^
echo This line is part of the remark

REM followed by some characters .:\/= works a bit different, it doesn't comment an ampersand, so you can use it as inline comment.

echo First & REM. This is a comment & echo second

But to avoid problems with existing files like REM, REM.bat or REM;.bat only a modified variant should be used.

REM^;<space>Comment

And for the character ; is also allowed one of ;,:\/=

REM is about 6 times slower than :: (tested on Win7SP1 with 100000 comment lines).
For a normal usage it's not important (58µs versus 360µs per comment line)

Comments with ::

A :: always executes a line end caret.

:: This is also a comment^
echo This line is also a comment

Labels and also the comment label :: have a special logic in parenthesis blocks.
They span always two lines SO: goto command not working.
So they are not recommended for parenthesis blocks, as they are often the cause for syntax errors.

With ECHO ON a REM line is shown, but not a line commented with ::

Both can't really comment out the rest of the line, so a simple %~ will cause a syntax error.

REM This comment will result in an error %~ ...

But REM is able to stop the batch parser at an early phase, even before the special character phase is done.

@echo ON
REM This caret ^ is visible

You can use &REM or &:: to add a comment to the end of command line. This approach works because '&' introduces a new command on the same line.

Comments with percent signs %= comment =%

There exists a comment style with percent signs.

In reality these are variables but they are expanded to nothing.
But the advantage is that they can be placed in the same line, even without &.
The equal sign ensures, that such a variable can't exists.

echo Mytest
set "var=3"     %= This is a comment in the same line=%

The percent style is recommended for batch macros, as it doesn't change the runtime behaviour, as the comment will be removed when the macro is defined.

set $test=(%\n%
%=Start of code=% ^
echo myMacro%\n%
)

As for your problem, currently you will have to depend on XHR or websockets for this.

Currently no popular browser has implemented any such raw sockets api for javascript that lets you create and access raw sockets, but a draft for the implementation of raw sockets api in JavaScript is under-way. Have a look at these links:
http://www.w3.org/TR/raw-sockets/
https://developer.mozilla.org/en-US/docs/Web/API/TCPSocket

Chrome now has support for raw TCP and UDP sockets in its ‘experimental’ APIs. These features are only available for extensions and, although documented, are hidden for the moment. Having said that, some developers are already creating interesting projects using it, such as this IRC client.

To access this API, you’ll need to enable the experimental flag in your extension’s manifest. Using sockets is pretty straightforward, for example:

chrome.experimental.socket.create('tcp', '127.0.0.1', 8080, function(socketInfo) {
  chrome.experimental.socket.connect(socketInfo.socketId, function (result) {
        chrome.experimental.socket.write(socketInfo.socketId, "Hello, world!");         
    });
});
