Using BalusC's suggestion of implementing Collection i can now hide my primefaces p:dataTable using not empty operator on my dataModel that extends javax.faces.model.ListDataModel

Code sample:

import java.io.Serializable;
import java.util.Collection;
import java.util.List;
import javax.faces.model.ListDataModel;
import org.primefaces.model.SelectableDataModel;

public class EntityDataModel extends ListDataModel<Entity> implements
        Collection<Entity>, SelectableDataModel<Entity>, Serializable {

    public EntityDataModel(List<Entity> data) { super(data); }

    @Override
    public Entity getRowData(String rowKey) {
        // In a real app, a more efficient way like a query by rowKey should be
        // implemented to deal with huge data
        List<Entity> entitys = (List<Entity>) getWrappedData();
        for (Entity entity : entitys) {
            if (Integer.toString(entity.getId()).equals(rowKey)) return entity;
        }
        return null;
    }

    @Override
    public Object getRowKey(Entity entity) {
        return entity.getId();
    }

    @Override
    public boolean isEmpty() {
        List<Entity> entity = (List<Entity>) getWrappedData();
        return (entity == null) || entity.isEmpty();
    }
    // ... other not implemented methods of Collection...
}

Funny, I recently had to do this.

function padDigits(number, digits) {
    return Array(Math.max(digits - String(number).length + 1, 0)).join(0) + number;
}

Use like:

padDigits(9, 4);  // "0009"
padDigits(10, 4); // "0010"
padDigits(15000, 4); // "15000"

Not beautiful, but effective.

If you want to clear apc cache in command : (use sudo if you need it)

APCu

php -r "apcu_clear_cache();" 

APC

php -r "apc_clear_cache(); apc_clear_cache('user'); apc_clear_cache('opcode');"

is is identity testing and == is equality testing (see the Python documentation).

In most cases, if a is b, then a == b. But there are exceptions, for example:

>>> nan = float('nan')
>>> nan is nan
True
>>> nan == nan
False

So, you can only use is for identity tests, never equality tests.

A solution could be to use a local file which retrieves the remote content

remoteInclude.php

<?php
$url = $_GET['url'];
$contents = file_get_contents($url);
echo $contents;

The HTML

<iframe frameborder="1" id="frametest" src="/remoteInclude.php?url=REMOTE_URL_HERE"></iframe>
<script>
    $("#frametest").load(function (){       
    var contents =$("#frametest").contents();
});

brew help. If brew is there, you get output. If not, you get 'command not found'. If you need to check in a script, you can work out how to redirect output and check $?.

.htaccess is a configuration file for use on web servers running the Apache Web Server software.

When a .htaccess file is placed in a directory which is in turn 'loaded via the Apache Web Server', then the .htaccess file is detected and executed by the Apache Web Server software.

These .htaccess files can be used to alter the configuration of the Apache Web Server software to enable/disable additional functionality and features that the Apache Web Server software has to offer.

These facilities include basic redirect functionality, for instance if a 404 file not found error occurs, or for more advanced functions such as content password protection or image hot link prevention.

Whenever any request is sent to the server it always passes through .htaccess file. There are some rules are defined to instruct the working.

sometime you missed some file like I missed my one file rt.java so better to check yours .........

The most important part is the concepts. Once you understand how the building blocks work, differences in syntax amount to little more than mild dialects. A layer on top of your regular expression engine's syntax is the syntax of the programming language you're using. Languages such as Perl remove most of this complication, but you'll have to keep in mind other considerations if you're using regular expressions in a C program.

If you think of regular expressions as building blocks that you can mix and match as you please, it helps you learn how to write and debug your own patterns but also how to understand patterns written by others.

Start simple

Conceptually, the simplest regular expressions are literal characters. The pattern N matches the character 'N'.

Regular expressions next to each other match sequences. For example, the pattern Nick matches the sequence 'N' followed by 'i' followed by 'c' followed by 'k'.

If you've ever used grep on Unix—even if only to search for ordinary looking strings—you've already been using regular expressions! (The re in grep refers to regular expressions.)

Order from the menu

Adding just a little complexity, you can match either 'Nick' or 'nick' with the pattern [Nn]ick. The part in square brackets is a character class, which means it matches exactly one of the enclosed characters. You can also use ranges in character classes, so [a-c] matches either 'a' or 'b' or 'c'.

The pattern . is special: rather than matching a literal dot only, it matches any character^†. It's the same conceptually as the really big character class [-.?+%$A-Za-z0-9...].

Think of character classes as menus: pick just one.

Helpful shortcuts

Using . can save you lots of typing, and there are other shortcuts for common patterns. Say you want to match a digit: one way to write that is [0-9]. Digits are a frequent match target, so you could instead use the shortcut \d. Others are \s (whitespace) and \w (word characters: alphanumerics or underscore).

The uppercased variants are their complements, so \S matches any non-whitespace character, for example.

Once is not enough

From there, you can repeat parts of your pattern with quantifiers. For example, the pattern ab?c matches 'abc' or 'ac' because the ? quantifier makes the subpattern it modifies optional. Other quantifiers are

• * (zero or more times)
• + (one or more times)
• {n} (exactly n times)
• {n,} (at least n times)
• {n,m} (at least n times but no more than m times)

Putting some of these blocks together, the pattern [Nn]*ick matches all of

• ick
• Nick
• nick
• Nnick
• nNick
• nnick
• (and so on)

The first match demonstrates an important lesson: * always succeeds! Any pattern can match zero times.

A few other useful examples:

• [0-9]+ (and its equivalent \d+) matches any non-negative integer
• \d{4}-\d{2}-\d{2} matches dates formatted like 2019-01-01

Grouping

A quantifier modifies the pattern to its immediate left. You might expect 0abc+0 to match '0abc0', '0abcabc0', and so forth, but the pattern immediately to the left of the plus quantifier is c. This means 0abc+0 matches '0abc0', '0abcc0', '0abccc0', and so on.

To match one or more sequences of 'abc' with zeros on the ends, use 0(abc)+0. The parentheses denote a subpattern that can be quantified as a unit. It's also common for regular expression engines to save or "capture" the portion of the input text that matches a parenthesized group. Extracting bits this way is much more flexible and less error-prone than counting indices and substr.

Alternation

Earlier, we saw one way to match either 'Nick' or 'nick'. Another is with alternation as in Nick|nick. Remember that alternation includes everything to its left and everything to its right. Use grouping parentheses to limit the scope of |, e.g., (Nick|nick).

For another example, you could equivalently write [a-c] as a|b|c, but this is likely to be suboptimal because many implementations assume alternatives will have lengths greater than 1.

Escaping

Although some characters match themselves, others have special meanings. The pattern \d+ doesn't match backslash followed by lowercase D followed by a plus sign: to get that, we'd use \\d\+. A backslash removes the special meaning from the following character.

Greediness

Regular expression quantifiers are greedy. This means they match as much text as they possibly can while allowing the entire pattern to match successfully.

For example, say the input is

"Hello," she said, "How are you?"

You might expect ".+" to match only 'Hello,' and will then be surprised when you see that it matched from 'Hello' all the way through 'you?'.

To switch from greedy to what you might think of as cautious, add an extra ? to the quantifier. Now you understand how \((.+?)\), the example from your question works. It matches the sequence of a literal left-parenthesis, followed by one or more characters, and terminated by a right-parenthesis.

If your input is '(123) (456)', then the first capture will be '123'. Non-greedy quantifiers want to allow the rest of the pattern to start matching as soon as possible.

(As to your confusion, I don't know of any regular-expression dialect where ((.+?)) would do the same thing. I suspect something got lost in transmission somewhere along the way.)

Anchors

Use the special pattern ^ to match only at the beginning of your input and $ to match only at the end. Making "bookends" with your patterns where you say, "I know what's at the front and back, but give me everything between" is a useful technique.

Say you want to match comments of the form

-- This is a comment --

you'd write ^--\s+(.+)\s+--$.

Build your own

Regular expressions are recursive, so now that you understand these basic rules, you can combine them however you like.

Footnote

†: The statement above that . matches any character is a simplification for pedagogical purposes that is not strictly true. Dot matches any character except newline, "\n", but in practice you rarely expect a pattern such as .+ to cross a newline boundary. Perl regexes have a /s switch and Java Pattern.DOTALL, for example, to make . match any character at all. For languages that don't have such a feature, you can use something like [\s\S] to match "any whitespace or any non-whitespace", in other words anything.

You can't choose a source/destination server.

If the databases are on the same server you can do this:

If the columns of the table are equal (including order!) then you can do this:

INSERT INTO [destination database].[dbo].[destination table]
SELECT *
FROM [source database].[dbo].[source table]

If you want to do this once you can backup/restore the source database. If you need to do this more often I recommend you start a SSIS project where you define source database (there you can choose any connection on any server) and create a project where you move your data there. See more information here: http://msdn.microsoft.com/en-us/library/ms169917%28v=sql.105%29.aspx

You can use the old way:

public List magicalListGetter() {
    List list = doMagicalVooDooHere();

    return list;
}

or you can use Object and the parent class of everything:

public List<Object> magicalListGetter() {
    List<Object> list = doMagicalVooDooHere();

    return list;
}

Note Perhaps there is a better parent class for all the objects you will put in the list. For example, Number would allow you to put Double and Integer in there.

Ahh, found the answer myself:

if (/[a-zA-Z]/.test(num)) {
  alert('Letter Found')
}

import csv
with open('input.csv','r') as csvinput:
    with open('output.csv', 'w') as csvoutput:
        writer = csv.writer(csvoutput)

        for row in csv.reader(csvinput):
            if row[0] == "Name":
                writer.writerow(row+["Berry"])
            else:
                writer.writerow(row+[row[0]])

Maybe something like that is what you intended?

Also, csv stands for comma separated values. So, you kind of need commas to separate your values like this I think:

Name,Code
blackberry,1
wineberry,2
rasberry,1
blueberry,1
mulberry,2

As far as I understood the problem, we can find palindromes around a center index and span our search both ways, to the right and left of the center. Given that and knowing there's no palindrome on the corners of the input, we can set the boundaries to 1 and length-1. While paying attention to the minimum and maximum boundaries of the String, we verify if the characters at the positions of the symmetrical indexes (right and left) are the same for each central position till we reach our max upper bound center.

The outer loop is O(n) (max n-2 iterations), and the inner while loop is O(n) (max around (n / 2) - 1 iterations)

Here's my Java implementation using the example provided by other users.

class LongestPalindrome {

    /**
     * @param input is a String input
     * @return The longest palindrome found in the given input.
     */
    public static String getLongestPalindrome(final String input) {
        int rightIndex = 0, leftIndex = 0;
        String currentPalindrome = "", longestPalindrome = "";
        for (int centerIndex = 1; centerIndex < input.length() - 1; centerIndex++) {
            leftIndex = centerIndex - 1;  rightIndex = centerIndex + 1;
            while (leftIndex >= 0 && rightIndex < input.length()) {
                if (input.charAt(leftIndex) != input.charAt(rightIndex)) {
                    break;
                }
                currentPalindrome = input.substring(leftIndex, rightIndex + 1);
                longestPalindrome = currentPalindrome.length() > longestPalindrome.length() ? currentPalindrome : longestPalindrome;
                leftIndex--;  rightIndex++;
            }
        }
        return longestPalindrome;
    }

    public static void main(String ... args) {
        String str = "HYTBCABADEFGHABCDEDCBAGHTFYW12345678987654321ZWETYGDE";
        String longestPali = getLongestPalindrome(str);
        System.out.println("String: " + str);
        System.out.println("Longest Palindrome: " + longestPali);
    }
}

The output of this is the following:

marcello:datastructures marcello$ javac LongestPalindrome
marcello:datastructures marcello$ java LongestPalindrome
String: HYTBCABADEFGHABCDEDCBAGHTFYW12345678987654321ZWETYGDE
Longest Palindrome: 12345678987654321

As the following answer describes: Does pandas/scipy/numpy provide a cumulative standard deviation function? The Python Pandas module contains a method to calculate the running or cumulative standard deviation. For that you'll have to convert your data into a pandas dataframe (or a series if it is 1D), but there are functions for that.

You can apply click on body of document and cancel click processing if the click event is generated by div with id menu_content, This will bind event to single element and saving binding of click with every element except menu_content

$('body').click(function(evt){    
       if(evt.target.id == "menu_content")
          return;
       //For descendants of menu_content being clicked, remove this check if you do not want to put constraint on descendants.
       if($(evt.target).closest('#menu_content').length)
          return;             

      //Do processing of click event here for every element except with id menu_content

});

You have to declare the array variable as an array:

Dim test(10) As Variant

You should only use extern template to force the compiler to not instantiate a template when you know that it will be instantiated somewhere else. It is used to reduce compile time and object file size.

For example:

// header.h

template<typename T>
void ReallyBigFunction()
{
    // Body
}

// source1.cpp

#include "header.h"
void something1()
{
    ReallyBigFunction<int>();
}

// source2.cpp

#include "header.h"
void something2()
{
    ReallyBigFunction<int>();
}

This will result in the following object files:

source1.o
    void something1()
    void ReallyBigFunction<int>()    // Compiled first time

source2.o
    void something2()
    void ReallyBigFunction<int>()    // Compiled second time

If both files are linked together, one void ReallyBigFunction<int>() will be discarded, resulting in wasted compile time and object file size.

To not waste compile time and object file size, there is an extern keyword which makes the compiler not compile a template function. You should use this if and only if you know it is used in the same binary somewhere else.

Changing source2.cpp to:

// source2.cpp

#include "header.h"
extern template void ReallyBigFunction<int>();
void something2()
{
    ReallyBigFunction<int>();
}

Will result in the following object files:

source1.o
    void something1()
    void ReallyBigFunction<int>() // compiled just one time

source2.o
    void something2()
    // No ReallyBigFunction<int> here because of the extern

When both of these will be linked together, the second object file will just use the symbol from the first object file. No need for discard and no wasted compile time and object file size.

This should only be used within a project, like in times when you use a template like vector<int> multiple times, you should use extern in all but one source file.

This also applies to classes and function as one, and even template member functions.

If the function you called returns null, it means your phone number is not registered in your contact list.

If instead of the phone number you just need an unique number, you may use the sim card's serial number:

    TelephonyManager telemamanger = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
    String getSimSerialNumber = telemamanger.getSimSerialNumber();  

I know it is a 100 year old post, but anyway, thought it might be useful to someone. You can put an invisible image somewhere on the page pointing to the url that needs to run in the background, like this:

<img src="run-in-background.php" border="0" alt="" width="1" height="1" />

This question has been addressed, in a slightly different form, at length, here:

RESTful Authentication

But this addresses it from the server-side. Let's look at this from the client-side. Before we do that, though, there's an important prelude:

Javascript Crypto is Hopeless

Matasano's article on this is famous, but the lessons contained therein are pretty important:

https://www.nccgroup.trust/us/about-us/newsroom-and-events/blog/2011/august/javascript-cryptography-considered-harmful/

To summarize:

• A man-in-the-middle attack can trivially replace your crypto code with <script> function hash_algorithm(password){ lol_nope_send_it_to_me_instead(password); }</script>
• A man-in-the-middle attack is trivial against a page that serves any resource over a non-SSL connection.
• Once you have SSL, you're using real crypto anyways.

And to add a corollary of my own:

• A successful XSS attack can result in an attacker executing code on your client's browser, even if you're using SSL - so even if you've got every hatch battened down, your browser crypto can still fail if your attacker finds a way to execute any javascript code on someone else's browser.

This renders a lot of RESTful authentication schemes impossible or silly if you're intending to use a JavaScript client. Let's look!

HTTP Basic Auth

First and foremost, HTTP Basic Auth. The simplest of schemes: simply pass a name and password with every request.

This, of course, absolutely requires SSL, because you're passing a Base64 (reversibly) encoded name and password with every request. Anybody listening on the line could extract username and password trivially. Most of the "Basic Auth is insecure" arguments come from a place of "Basic Auth over HTTP" which is an awful idea.

The browser provides baked-in HTTP Basic Auth support, but it is ugly as sin and you probably shouldn't use it for your app. The alternative, though, is to stash username and password in JavaScript.

This is the most RESTful solution. The server requires no knowledge of state whatsoever and authenticates every individual interaction with the user. Some REST enthusiasts (mostly strawmen) insist that maintaining any sort of state is heresy and will froth at the mouth if you think of any other authentication method. There are theoretical benefits to this sort of standards-compliance - it's supported by Apache out of the box - you could store your objects as files in folders protected by .htaccess files if your heart desired!

The problem? You are caching on the client-side a username and password. This gives evil.ru a better crack at it - even the most basic of XSS vulnerabilities could result in the client beaming his username and password to an evil server. You could try to alleviate this risk by hashing and salting the password, but remember: JavaScript Crypto is Hopeless. You could alleviate this risk by leaving it up to the Browser's Basic Auth support, but.. ugly as sin, as mentioned earlier.

HTTP Digest Auth

Is Digest authentication possible with jQuery?

A more "secure" auth, this is a request/response hash challenge. Except JavaScript Crypto is Hopeless, so it only works over SSL and you still have to cache the username and password on the client side, making it more complicated than HTTP Basic Auth but no more secure.

Query Authentication with Additional Signature Parameters.

Another more "secure" auth, where you encrypt your parameters with nonce and timing data (to protect against repeat and timing attacks) and send the. One of the best examples of this is the OAuth 1.0 protocol, which is, as far as I know, a pretty stonking way to implement authentication on a REST server.

http://tools.ietf.org/html/rfc5849

Oh, but there aren't any OAuth 1.0 clients for JavaScript. Why?

JavaScript Crypto is Hopeless, remember. JavaScript can't participate in OAuth 1.0 without SSL, and you still have to store the client's username and password locally - which puts this in the same category as Digest Auth - it's more complicated than HTTP Basic Auth but it's no more secure.

Token

The user sends a username and password, and in exchange gets a token that can be used to authenticate requests.

This is marginally more secure than HTTP Basic Auth, because as soon as the username/password transaction is complete you can discard the sensitive data. It's also less RESTful, as tokens constitute "state" and make the server implementation more complicated.

SSL Still

The rub though, is that you still have to send that initial username and password to get a token. Sensitive information still touches your compromisable JavaScript.

To protect your user's credentials, you still need to keep attackers out of your JavaScript, and you still need to send a username and password over the wire. SSL Required.

Token Expiry

It's common to enforce token policies like "hey, when this token has been around too long, discard it and make the user authenticate again." or "I'm pretty sure that the only IP address allowed to use this token is XXX.XXX.XXX.XXX". Many of these policies are pretty good ideas.

Firesheeping

However, using a token Without SSL is still vulnerable to an attack called 'sidejacking': http://codebutler.github.io/firesheep/

The attacker doesn't get your user's credentials, but they can still pretend to be your user, which can be pretty bad.

tl;dr: Sending unencrypted tokens over the wire means that attackers can easily nab those tokens and pretend to be your user. FireSheep is a program that makes this very easy.

A Separate, More Secure Zone

The larger the application that you're running, the harder it is to absolutely ensure that they won't be able to inject some code that changes how you process sensitive data. Do you absolutely trust your CDN? Your advertisers? Your own code base?

Common for credit card details and less common for username and password - some implementers keep 'sensitive data entry' on a separate page from the rest of their application, a page that can be tightly controlled and locked down as best as possible, preferably one that is difficult to phish users with.

Cookie (just means Token)

It is possible (and common) to put the authentication token in a cookie. This doesn't change any of the properties of auth with the token, it's more of a convenience thing. All of the previous arguments still apply.

Session (still just means Token)

Session Auth is just Token authentication, but with a few differences that make it seem like a slightly different thing:

• Users start with an unauthenticated token.
• The backend maintains a 'state' object that is tied to a user's token.
• The token is provided in a cookie.
• The application environment abstracts the details away from you.

Aside from that, though, it's no different from Token Auth, really.

This wanders even further from a RESTful implementation - with state objects you're going further and further down the path of plain ol' RPC on a stateful server.

OAuth 2.0

OAuth 2.0 looks at the problem of "How does Software A give Software B access to User X's data without Software B having access to User X's login credentials."

The implementation is very much just a standard way for a user to get a token, and then for a third party service to go "yep, this user and this token match, and you can get some of their data from us now."

Fundamentally, though, OAuth 2.0 is just a token protocol. It exhibits the same properties as other token protocols - you still need SSL to protect those tokens - it just changes up how those tokens are generated.

There are two ways that OAuth 2.0 can help you:

• Providing Authentication/Information to Others
• Getting Authentication/Information from Others

But when it comes down to it, you're just... using tokens.

Back to your question

So, the question that you're asking is "should I store my token in a cookie and have my environment's automatic session management take care of the details, or should I store my token in Javascript and handle those details myself?"

And the answer is: do whatever makes you happy.

The thing about automatic session management, though, is that there's a lot of magic happening behind the scenes for you. Often it's nicer to be in control of those details yourself.

I am 21 so SSL is yes

The other answer is: Use https for everything or brigands will steal your users' passwords and tokens.

I realize this is an old question. I found it several months ago when I was trying to do the same thing, and was underwhelmed by the answers given. They all seemed to deal with importing from Bitbucket to GitHub one repository at a time, either via commands issued à la carte, or via the GitHub importer.

I grabulated the code from a GitHub project called gitter and modified it to suite my needs.

You can fork the gist, or take the code from here:

Then, to use the script:

# create a list of repos
foo
bar
baz

# execute the script, iterating over your list
while read p; do ./bitbucket-to-github.rb -a -n $p; done<repos

# good nuff

You can use zip(), which will "interleave" the two arrays together, and then map(), which will apply a function to each element in an iterable:

>>> a = [1,2,3,4,5]
>>> b = [6,7,8,9,10]
>>> zip(a, b)
[(1, 6), (2, 7), (3, 8), (4, 9), (5, 10)]
>>> map(lambda x: x[0] + x[1], zip(a, b))
[7, 9, 11, 13, 15]

You can use the SYS_GUID() function to generate a GUID in your insert statement:

insert into mytable (guid_col, data) values (sys_guid(), 'xxx');

The preferred datatype for storing GUIDs is RAW(16).

As Gopinath answer:

 select sys_guid() from dual
 union all
 select sys_guid() from dual
 union all 
 select sys_guid() from dual

You get

88FDC68C75DDF955E040449808B55601
88FDC68C75DEF955E040449808B55601
88FDC68C75DFF955E040449808B55601

As Tony Andrews says, differs only at one character

Check if data is a empty string (and ignore any white space) with jQuery:

function isBlank( data ) {
    return ( $.trim(data).length == 0 );
}

I had this problem and the issue was that I had the package loaded in another R instance. Simply closing all R instances and installing on a fresh instance allowed for the package to be installed.

Generally, you can also install if every remaining instance has never loaded the package as well (even if it installed an old version).

In onclik function replace first line with this line u will definitely get right result.

if (passw1.getText().toString().equalsIgnoreCase("1234") && passw2.getText().toString().equalsIgnoreCase("1234")){

You can null/blank/space Etc value using LinQ Use Following Query

   var BlankValueRows = (from dr1 in Dt.AsEnumerable()
                                  where dr1["Columnname"].ToString() == ""
                                  || dr1["Columnname"].ToString() == ""
                                   || dr1["Columnname"].ToString() == ""
                                  select Columnname);

Here Replace Columnname with table column name and "" your search item in above code we looking null value.

Unless your do_something function actually does something with any given arguments, you can just pass it as the event handler.

var first = document.getElementById('first');
first.addEventListener('touchstart', do_something, false);
first.addEventListener('click', do_something, false);

There are several of this same question (1, 2). One way of doing it is using canvas. Here's a working solution. Here you can see some working examples of using this library.

Add a -v flag with your git command . e.g. git pull -v

v stands for verify .

I want to add to the answers posted on above that none of the solutions proposed here worked for me. My WAMP, is working on port 3308 instead of 3306 which is what it is installed by default. I found out that when working in a local environment, if you are using mysqladmin in your computer (for testing environment), and if you are working with port other than 3306, you must define your variable DB_SERVER with the value localhost:NumberOfThePort, so it will look like the following: define("DB_SERVER", "localhost:3308"). You can obtain this value by right-clicking on the WAMP icon in your taskbar (on the hidden icons section) and select Tools. You will see the section: "Port used by MySQL: NumberOfThePort"

This will fix your connection to your database.

This was the error I got: Error: SQLSTATE[HY1045] Access denied for user 'username'@'localhost' on line X.

I hope this helps you out.

cout is in std namespace, you shall use std::cout in your code. And you shall not add using namespace std; in your header file, it's bad to mix your code with std namespace, especially don't add it in header file.

ListView operates based on the underlying data in the Adapter. In order to clear the ListView you need to do two things:

1. Clear the data that you set from adapter.
2. Refresh the view by calling notifyDataSetChanged

For example, see the skeleton of SampleAdapter below that extends the BaseAdapter

public class SampleAdapter extends BaseAdapter {

    ArrayList<String> data;

    public SampleAdapter() {
        this.data = new ArrayList<String>();
    }

    public int getCount() {
        return data.size();
    }

    public Object getItem(int position) {
        return data.get(position);
    }

    public long getItemId(int position) {
        return position;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        // your View
        return null;
    }
}

Here you have the ArrayList<String> data as the data for your Adapter. While you might not necessary use ArrayList, you will have something similar in your code to represent the data in your ListView

Next you provide a method to clear this data, the implementation of this method is to clear the underlying data structure

public void clearData() {
    // clear the data
    data.clear();
}

If you are using any subclass of Collection, they will have clear() method that you could use as above.

Once you have this method, you want to call clearData and notifyDataSetChanged on your onClick thus the code for onClick will look something like:

// listView is your instance of your ListView
SampleAdapter sampleAdapter = (SampleAdapter)listView.getAdapter();
sampleAdapter.clearData();

// refresh the View
sampleAdapter.notifyDataSetChanged();

One way to do this is to insert a dummy column with the sums in order to sort:

In [10]: sum_B_over_A = df.groupby('A').sum().B

In [11]: sum_B_over_A
Out[11]: 
A
bar    0.253652
baz   -2.829711
foo    0.551376
Name: B

in [12]: df['sum_B_over_A'] = df.A.apply(sum_B_over_A.get_value)

In [13]: df
Out[13]: 
     A         B      C  sum_B_over_A
0  foo  1.624345  False      0.551376
1  bar -0.611756   True      0.253652
2  baz -0.528172  False     -2.829711
3  foo -1.072969   True      0.551376
4  bar  0.865408  False      0.253652
5  baz -2.301539   True     -2.829711

In [14]: df.sort(['sum_B_over_A', 'A', 'B'])
Out[14]: 
     A         B      C   sum_B_over_A
5  baz -2.301539   True      -2.829711
2  baz -0.528172  False      -2.829711
1  bar -0.611756   True       0.253652
4  bar  0.865408  False       0.253652
3  foo -1.072969   True       0.551376
0  foo  1.624345  False       0.551376

and maybe you would drop the dummy row:

In [15]: df.sort(['sum_B_over_A', 'A', 'B']).drop('sum_B_over_A', axis=1)
Out[15]: 
     A         B      C
5  baz -2.301539   True
2  baz -0.528172  False
1  bar -0.611756   True
4  bar  0.865408  False
3  foo -1.072969   True
0  foo  1.624345  False

According to @zombat's answer, it's better to validate the Anonymous Functions first:

function exampleMethod($anonFunc) {
    //execute anonymous function
    if (is_callable($anonFunc)) {
        $anonFunc();
    }
}

Or validate argument type since PHP 5.4.0:

function exampleMethod(callable $anonFunc) {}

Create a temporary element (e. g. DIV), assign your HTML code to its innerHTML property, and then append its child nodes to the HEAD element one by one. For example, like this:

var temp = document.createElement('div');

temp.innerHTML = '<link rel="stylesheet" href="example.css" />'
               + '<script src="foobar.js"><\/script> ';

var head = document.head;

while (temp.firstChild) {
    head.appendChild(temp.firstChild);
}

Compared with rewriting entire HEAD contents via its innerHTML, this wouldn’t affect existing child elements of the HEAD element in any way.

Note that scripts inserted this way are apparently not executed automatically, while styles are applied successfully. So if you need scripts to be executed, you should load JS files using Ajax and then execute their contents using eval().

On Ubuntu, placed your id_rsa and id_rsa.pub files in /var/lib/jenkins/.ssh

Make Jenkins own them sudo chown -R jenkins /var/lib/jenkins/.ssh/

Make sure that Jenkins key is added as deploy key with RW access in GitHub (or similar) - use the id_rsa.pub key for this.

Now everything should jive with the SCM Sync Plugin.

I guess ch is a declared as char. Since char is a primitive data type and not and object, you can't call any methof from it. You should use Character.isLetter(ch).

People mentioned string.find(), string.index(), and string.indexOf() in the comments, and I summarize them here (according to the Python Documentation):

First of all there is not a string.indexOf() method. The link posted by Deviljho shows this is a JavaScript function.

Second the string.find() and string.index() actually return the index of a substring. The only difference is how they handle the substring not found situation: string.find() returns -1 while string.index() raises an ValueError.

As of August 8th, 2016, FQLs are deprecated.

Update 10/2017 (v2.10):

Here's a non-deprecated way to get a given URL's like and share count (no access token required):

https://graph.facebook.com/?fields=og_object{likes.summary(total_count).limit(0)},share&id=https://www.stackoverflow.com

Result:

{
   "og_object": {
      "likes": {
         "data": [

         ],
         "summary": {
            "total_count": 83
         }
      },
      "id": "10151023731873397"
   },
   "share": {
      "comment_count": 0,
      "share_count": 2915
   },
   "id": "https://www.stackoverflow.com"
}

JQuery Example:

$.get('https://graph.facebook.com/'
    + '?fields=og_object{likes.summary(total_count).limit(0)},share&id='
    + url-goes-here,
    function (data) {
        if (data) {
            var like_count = data.og_object.likes.summary.total_count;
            var share_count = data.share.share_count;
        }
    });

This is the reason why you should whenever possible use strict equality === or strict inequality !==

"100" == 100

true because this only checks value, not the data type

"100" === 100

false this checks value and data type

From tutorial here

"It has the extremely useful property that if all of the edges in a graph are unweighted (or the same weight) then the first time a node is visited is the shortest path to that node from the source node"

    WHERE FIND_IN_SET(c.CompanyID , o.attachedCompanyIDs) GROUP BY o.attachedCompanyIDs

You can designate a button as the "AcceptButton" in the Form's properties and that will catch any "Enter" keypresses on the form and route them to that control.

See How to: Designate a Windows Forms Button as the Accept Button Using the Designer and note the few exceptions it outlines (multi-line text-boxes, etc.)

Search for [ ]{2,}. This will find two or more adjacent spaces anywhere within the line. It will also match leading and trailing spaces as well as lines that consist entirely of spaces. If you don't want that, check out Alexander's answer.

Actually, you can leave out the brackets, they are just for clarity (otherwise the space character that is being repeated isn't that well visible :)).

The problem with \s{2,} is that it will also match newlines on Windows files (where newlines are denoted by CRLF or \r\n which is matched by \s{2}.

If you also want to find multiple tabs and spaces, use [ \t]{2,}.

Using new ES6 Object.entries(), it makes for a fun little nested map/join:

const encodeGetParams = p => _x000D_
  Object.entries(p).map(kv => kv.map(encodeURIComponent).join("=")).join("&");_x000D_
_x000D_
const params = {_x000D_
  user: "María Rodríguez",_x000D_
  awesome: true,_x000D_
  awesomeness: 64,_x000D_
  "ZOMG+&=*(": "*^%*GMOZ"_x000D_
};_x000D_
_x000D_
console.log("https://example.com/endpoint?" + encodeGetParams(params))

The accepted answer suffers from a race condition if two such scripts are executed concurrently on the same Postgres cluster (DB server), as is common in continuous-integration environments.

It's generally safer to try to create the role and gracefully deal with problems when creating it:

DO $$
BEGIN
  CREATE ROLE my_role WITH NOLOGIN;
  EXCEPTION WHEN DUPLICATE_OBJECT THEN
  RAISE NOTICE 'not creating role my_role -- it already exists';
END
$$;

brew help will show you the list of commands that are available.

brew list will show you the list of installed packages. You can also append formulae, for example brew list postgres will tell you of files installed by postgres (providing it is indeed installed).

brew search <search term> will list the possible packages that you can install. brew search post will return multiple packages that are available to install that have post in their name.

brew info <package name> will display some basic information about the package in question.

You can also search http://searchbrew.com or https://brewformulas.org (both sites do basically the same thing)

See the Stack Trace facility in ACE (ADAPTIVE Communication Environment). It's already written to cover all major platforms (and more). The library is BSD-style licensed so you can even copy/paste the code if you don't want to use ACE.

Git itself has no provision to specify the repository name. The root directory's name is the single source of truth pertaining to the repository name.

The .git/description though is used only by some applications, like GitWeb.

To make your item consistent with the system look and feel try referencing the system attribute android:attr/selectableItemBackground in your desired view's background or foreground tag:

<ImageView
    ...
    android:background="?android:attr/selectableItemBackground"      
    android:foreground="?android:attr/selectableItemBackground"
    ...
/>

Use both attributes to get desired effect before/after API level 23 respectively.

You have endless loop in place:

function save() {
    var filename = id('filename').value;
    var name = id('name').value;
    var text = id('text').value;
    save(filename, name, text);
}

No idea what you're trying to accomplish with that endless loop but first of all get rid of it and see if things are working.

Some posts have showed how to display the command's progress. In order to calculate it, you'll need to see how much you've progressed. On BSD systems some commands, such as dd(1), accept a SIGINFO signal, and will report their progress. On Linux systems some commands will respond similarly to SIGUSR1. If this facility is available, you can pipe your input through dd to monitor the number of bytes processed.

Alternatively, you can use lsof to obtain the offset of the file's read pointer, and thereby calculate the progress. I've written a command, named pmonitor, that displays the progress of processing a specified process or file. With it you can do things, such as the following.

$ pmonitor -c gzip
/home/dds/data/mysql-2015-04-01.sql.gz 58.06%

An earlier version of Linux and FreeBSD shell scripts appears on my blog.

\b matches a word-boundary. \B matches non-word-boundaries, and is equivalent to [^\b](?!\b) _{^{(thanks to @Alan Moore for the correction!)}}. Both are zero-width.

Other answers show how to use pip with both 2.X and 3.X Python, but does not show how to handle the case of multiple Python distributions (eg. original Python and Anaconda Python).

I have a total of 3 Python versions: original Python 2.7 and Python 3.5 and Anaconda Python 3.5.

Here is how I install a package into:

1. Original Python 3.5:

   /usr/bin/python3 -m pip install python-daemon
   

2. Original Python 2.7:

   /usr/bin/python -m pip install python-daemon
   

3. Anaconda Python 3.5:

   python3 -m pip install python-daemon
   

   or

   pip3 install python-daemon
   

   Simpler, as Anaconda overrides original Python binaries in user environment.

   Of course, installing in anaconda should be done with conda command, this is just an example.

Also, make sure that pip is installed for that specific python.You might need to manually install pip. This works in Ubuntu 16.04:

sudo apt-get install python-pip 

or

sudo apt-get install python3-pip

If you want to get a file from a specific hash + a remote repository I've tried git-archive and it didn't work.

Use a iterator to loop through list and then delete the required object.

    Iterator itr = a.iterator();

    }

sentence.sub! 'Robert', 'Joe'

Won't cause an exception if the replaced word isn't in the sentence (the []= variant will).

How to replace all instances?

The above replaces only the first instance of "Robert".

To replace all instances use gsub/gsub! (ie. "global substitution"):

sentence.gsub! 'Robert', 'Joe'

The above will replace all instances of Robert with Joe.

Reinstall node, then update npm.

First I removed node

apt-get purge node

Then install node according to the distibution. Docs here .

Then

npm install npm@latest -g

You are on the right track.

On your header set

Content-Type: application/x-www-form-urlencoded

The body of the POST request should be =test and nothing else. For unknown/variable strings you have to URL encode the value so that way you do not accidentally escape with an input character.

I had this issue with my pagination forward and backward link .... simply set (int ) in front of the variable $Page+1 and it worked...

<?php 
$Page = (isset($_GET['Page']) ? $_GET['Page'] : '');
if ((int)$Page+1<=$PostPagination) {
?>
<li> <a href="Index.php?Page=<?php echo $Page+1; ?>"> &raquo;</a></li>
<?php }
?>

Here's another take on this. contextlib.redirect_stdout with io.StringIO() as documented is great, but it's still a bit verbose for every day use. Here's how to make it a one-liner by subclassing contextlib.redirect_stdout:

import sys
import io
from contextlib import redirect_stdout

class capture(redirect_stdout):

    def __init__(self):
        self.f = io.StringIO()
        self._new_target = self.f
        self._old_targets = []  # verbatim from parent class

    def __enter__(self):
        self._old_targets.append(getattr(sys, self._stream))  # verbatim from parent class
        setattr(sys, self._stream, self._new_target)  # verbatim from parent class
        return self  # instead of self._new_target in the parent class

    def __repr__(self):
        return self.f.getvalue()  

Since __enter__ returns self, you have the context manager object available after the with block exits. Moreover, thanks to the __repr__ method, the string representation of the context manager object is, in fact, stdout. So now you have,

with capture() as message:
    print('Hello World!')
print(str(message)=='Hello World!\n')  # returns True

private function sendHttpRequest($host, $path, $query, $port=80){
    header("POST $path HTTP/1.1\r\n" );
    header("Host: $host\r\n" );
    header("Content-type: application/x-www-form-urlencoded\r\n" );
    header("Content-length: " . strlen($query) . "\r\n" );
    header("Connection: close\r\n\r\n" );
    header($query);
}

This will get you right away

If i go by Grodriguez's answer

System.out.println("" + value);
value = value.setScale(0, BigDecimal.ROUND_HALF_UP);
System.out.println("" + value);

This is the output

100.23 -> 100
100.77 -> 101

Which isn't quite what i want, so i ended up doing this..

System.out.println("" + value);
value = value.setScale(0, BigDecimal.ROUND_HALF_UP);
value = value.setScale(2, BigDecimal.ROUND_HALF_UP);
System.out.println("" + value);

This is what i get

100.23 -> 100.00
100.77 -> 101.00

This solves my problem for now .. : ) Thank you all.

Simply you can read XML file as dataType: "xml", it will retuen xml object already parsed. you can use it as jquery object and find anything or loop throw it…etc.

$(document).ready(function(){
   $.ajax({
    type: "GET" ,
    url: "sampleXML.xml" ,
    dataType: "xml" ,
    success: function(xml) {

    //var xmlDoc = $.parseXML( xml );   <------------------this line
    //if single item
    var person = $(xml).find('person').text();  

    //but if it's multible items then loop
    $(xml).find('person').each(function(){
     $("#temp").append('<li>' + $(this).text() + '</li>');  
    }); 
    }       
});
});

I have slightly modified the jangorecki function for the case where we may have a variety of values that cannot be converted to a number. In my function, a template search is performed and if the template is not found, FALSE is returned.! before gperl, it means that we need those vector elements that do not match the template. The rest is similar to the as.num function. Example:

as.num.pattern <- function(x, pattern){
  stopifnot(is.character(x))
  na = !grepl(pattern, x)
  x[na] = -Inf
  x = as.numeric(x)
  x[na] = NA_real_
  x
}

as.num.pattern(c('1', '2', '3.43', 'char1', 'test2', 'other3', '23/40', '23, 54 cm.'))

[1] 1.00 2.00 3.43   NA   NA   NA   NA   NA

Another way to do it is using a limit method:

Listing::limit(10)->get();

This can be useful if you're not trying to implement pagination, but for example, return 10 random rows from a table:

Listing::inRandomOrder()->limit(10)->get();

Using filter() and lambda would provide a neat and terse method of removing unwanted values:

newEmails = list(filter(lambda x : x != '[email protected]', emails))

This does not modify emails. It creates the new list newEmails containing only elements for which the anonymous function returned True.

If you need the checkbox to be submitted with the form but effectively read-only to the user, I recommend setting them to disabled and using javascript to re-enable them when the form is submitted.

This is for two reasons. First and most important, your users benefit from seeing a visible difference between checkboxes they can change and checkboxes which are read-only. Disabled does this.

Second reason is that the disabled state is built into the browser so you need less code to execute when the user clicks on something. This is probably more of a personal preference than anything else. You'll still need some javascript to un-disable these when submitting the form.

It seems easier to me to use some javascript when the form is submitted to un-disable the checkboxes than to use a hidden input to carry the value.

Taken from Scott Hanselman's Blog:

public static bool IsNumeric(object expression)
{
    if (expression == null)
    return false;

    double number;
    return Double.TryParse( Convert.ToString( expression
                                            , CultureInfo.InvariantCulture)
                          , System.Globalization.NumberStyles.Any
                          , NumberFormatInfo.InvariantInfo
                          , out number);
}

You need to add in the seconds, too:

unsigned long time_in_micros = 1000000 * tv.tv_sec + tv.tv_usec;

Note that this will only last for about 2³²/10⁶ =~ 4295 seconds, or roughly 71 minutes though (on a typical 32-bit system).

To disable all form, as easy as write:

jQuery 1.6+

$("#form :input").prop("disabled", true);

jQuery 1.5 and below

$("#form :input").attr('disabled','disabled');

Case-statements automatically fall through if you don't specify otherwise (by writing break). Therefor you can write

switch(myvar)
{
   case 2:
   case 5:
   {
      //your code
   break;
   }

// etc... }

Add the image to Your project by clicking File -> "Add Files to ...".

Then choose the image in ImageView properties (Utilities -> Attributes Inspector).

A third great alternative is using the package data.table, which also has the class data.frame, but operations like you are looking for are computed much faster.

library(data.table)
mydt <- structure(list(Name = c("Aira", "Aira", "Aira", "Ben", "Ben", "Ben", "Cat", "Cat", "Cat"), Month = c(1L, 2L, 3L, 1L, 2L, 3L, 1L, 2L, 3L), Rate1 = c(15.6396600443877, 2.15649279424609, 6.24692918928743, 2.37658797276116, 34.7500663272292, 3.28750138697048, 29.3265553981065, 17.9821839334431, 10.8639802575958), Rate2 = c(17.1680489538369, 5.84231656330206, 8.54330866437461, 5.88415184986176, 3.02064294862551, 17.2053351400752, 16.9552950199166, 2.56058000170089, 15.7496228048122)), .Names = c("Name", "Month", "Rate1", "Rate2"), row.names = c(NA, -9L), class = c("data.table", "data.frame"))

Now to take the mean of Rate1 and Rate2 for all 3 months, for each person (Name): First, decide which columns you want to take the mean of

colstoavg <- names(mydt)[3:4]

Now we use lapply to take the mean over the columns we want to avg (colstoavg)

mydt.mean <- mydt[,lapply(.SD,mean,na.rm=TRUE),by=Name,.SDcols=colstoavg]

 mydt.mean
   Name     Rate1     Rate2
1: Aira  8.014361 10.517891
2:  Ben 13.471385  8.703377
3:  Cat 19.390907 11.755166

It is used in transaction management to ensure that any errors result in the transaction being rolled back.

Google Guava is another choice to encode and decode Base64 data:

POM configuration:

<dependency>
   <artifactId>guava</artifactId>
   <groupId>com.google.guava</groupId>
   <type>jar</type>
   <version>14.0.1</version>
</dependency>

Sample code:

String inputContent = "Hello Vi?t Nam";
String base64String = BaseEncoding.base64().encode(inputContent.getBytes("UTF-8"));

// Decode
System.out.println("Base64:" + base64String); // SGVsbG8gVmnhu4d0IE5hbQ==
byte[] contentInBytes = BaseEncoding.base64().decode(base64String);
System.out.println("Source content: " + new String(contentInBytes, "UTF-8")); // Hello Vi?t Nam

var strArray = [ "q", "w", "w", "e", "i", "u", "r", "q"];
var alreadySeen = [];

strArray.forEach(function(str) {
  if (alreadySeen[str])
    alert(str);
  else
    alreadySeen[str] = true;
});

I added another duplicate in there from your original just to show it would find a non-consecutive duplicate.

Updated version with arrow function:

const strArray = [ "q", "w", "w", "e", "i", "u", "r", "q"];
const alreadySeen = [];

strArray.forEach(str => alreadySeen[str] ? alert(str) : alreadySeen[str] = true);

sb.AppendLine();

or

sb.Append( "\n" );

And

sb.Append( "\t" );

If I understand the question, you may interested in this example in the Matplotlib gallery.

Yann's comment above provides a similar example.

Edit - Link above fixed. Corresponding code copied from the Matplotlib gallery:

from mpl_toolkits.axes_grid1 import host_subplot
import mpl_toolkits.axisartist as AA
import matplotlib.pyplot as plt

host = host_subplot(111, axes_class=AA.Axes)
plt.subplots_adjust(right=0.75)

par1 = host.twinx()
par2 = host.twinx()

offset = 60
new_fixed_axis = par2.get_grid_helper().new_fixed_axis
par2.axis["right"] = new_fixed_axis(loc="right", axes=par2,
                                        offset=(offset, 0))

par2.axis["right"].toggle(all=True)

host.set_xlim(0, 2)
host.set_ylim(0, 2)

host.set_xlabel("Distance")
host.set_ylabel("Density")
par1.set_ylabel("Temperature")
par2.set_ylabel("Velocity")

p1, = host.plot([0, 1, 2], [0, 1, 2], label="Density")
p2, = par1.plot([0, 1, 2], [0, 3, 2], label="Temperature")
p3, = par2.plot([0, 1, 2], [50, 30, 15], label="Velocity")

par1.set_ylim(0, 4)
par2.set_ylim(1, 65)

host.legend()

host.axis["left"].label.set_color(p1.get_color())
par1.axis["right"].label.set_color(p2.get_color())
par2.axis["right"].label.set_color(p3.get_color())

plt.draw()
plt.show()

#plt.savefig("Test")

First we'll consider loops where the number of iterations of the inner loop is independent of the value of the outer loop's index. For example:

 for (i = 0; i < N; i++) {
     for (j = 0; j < M; j++) {
         sequence of statements
      }
  }

The outer loop executes N times. Every time the outer loop executes, the inner loop executes M times. As a result, the statements in the inner loop execute a total of N * M times. Thus, the total complexity for the two loops is O(N2).

I would recommend using imagesLoaded.js javascript library.

Why not use jQuery's $(window).load()?

As ansered on https://stackoverflow.com/questions/26927575/why-use-imagesloaded-javascript-library-versus-jquerys-window-load/26929951

It's a matter of scope. imagesLoaded allows you target a set of images, whereas $(window).load() targets all assets — including all images, objects, .js and .css files, and even iframes. Most likely, imagesLoaded will trigger sooner than $(window).load() because it is targeting a smaller set of assets.

Other good reasons to use imagesloaded

• officially supported by IE8+
• license: MIT License
• dependencies: none
• weight (minified & gzipped) : 7kb minified (light!)

Use TestCase.assertRaises (or TestCase.failUnlessRaises) from the unittest module, for example:

import mymod

class MyTestCase(unittest.TestCase):
    def test1(self):
        self.assertRaises(SomeCoolException, mymod.myfunc)

The issue was with the dmp file itself. I had to re-export the file and the command works fine. Thank you @Justin Cave

To write the best code, you "should" use the latter approach, with a function reference:

var refreshId = setInterval(function() {}, 5000);

or

function test() {}
var refreshId = setInterval(test, 5000);

but your approach of

function test() {}
var refreshId = setInterval("test()", 5000);

is basically valid, too (as long as test() is global).

Note that there is no such thing really as "in jQuery". You're still writing the Javascript language; you're just using some pre-made functions that are the jQuery library.

The way to do this without use of plugins is to make a subclass of google's OverlayView() method.

https://developers.google.com/maps/documentation/javascript/reference?hl=en#OverlayView

You make a custom function and apply it to the map.

function Label() { 
    this.setMap(g.map);
};

Now you prototype your subclass and add HTML nodes:

Label.prototype = new google.maps.OverlayView; //subclassing google's overlayView
Label.prototype.onAdd = function() {
        this.MySpecialDiv               = document.createElement('div');
        this.MySpecialDiv.className     = 'MyLabel';
        this.getPanes().overlayImage.appendChild(this.MySpecialDiv); //attach it to overlay panes so it behaves like markers

}

you also have to implement remove and draw functions as stated in the API docs, or this won't work.

Label.prototype.onRemove = function() {
... // remove your stuff and its events if any
}
Label.prototype.draw = function() {
      var position = this.getProjection().fromLatLngToDivPixel(this.get('position')); // translate map latLng coords into DOM px coords for css positioning
var pos = this.get('position');
            $('.myLabel')
            .css({
                'top'   : position.y + 'px',
                'left'  : position.x + 'px'
            })
        ;
}

That's the gist of it, you'll have to do some more work in your specific implementation.

Most terse version I can think of

Len(Trim(TextBox1.Value)) = 0

If you need to do this multiple times, wrap it in a function

Public Function HasContent(text_box as Object) as Boolean
    HasContent = (Len(Trim(text_box.Value)) > 0)
End Function

Usage

If HasContent(TextBox1) Then
    ' ...

Note that the type(numpy.ndarray) is a type itself and watch out for boolean and scalar types. Don't be too discouraged if it's not intuitive or easy, it's a pain at first.

in python sorted works like you want with integers:

>>> sorted([10,3,2])
[2, 3, 10]

it looks like you have a problem because you are using strings:

>>> sorted(['10','3','2'])
['10', '2', '3']

(because string ordering starts with the first character, and "1" comes before "2", no matter what characters follow) which can be fixed with key=int

>>> sorted(['10','3','2'], key=int)
['2', '3', '10']

which converts the values to integers during the sort (it is called as a function - int('10') returns the integer 10)

and as suggested in the comments, you can also sort the list itself, rather than generating a new one:

>>> l = ['10','3','2']
>>> l.sort(key=int)
>>> l
['2', '3', '10']

but i would look into why you have strings at all. you should be able to save and retrieve integers. it looks like you are saving a string when you should be saving an int? (sqlite is unusual amongst databases, in that it kind-of stores data in the same type as it is given, even if the table column type is different).

and once you start saving integers, you can also get the list back sorted from sqlite by adding order by ... to the sql command:

select temperature from temperatures order by temperature;

1. Type cmd in program start
2. Copy and Paste following on dos prompt

set PATH="%PATH%;C:\Program Files\Java\jdk1.6.0_18\bin"

See this link http://momentjs.com/docs/#/displaying/unix-timestamp-milliseconds/

valueOf() is the function you're looking for.

Editing my answer (OP wants milliseconds of today, not since epoch)

You want the milliseconds() function OR you could go the route of moment().valueOf()

Well, you can always "give up" :)

Just copied this over here, because I almost missed it in the other thread.

From the first answer,

"Using Mongoose, a user can define the schema for the documents in a particular collection. It provides a lot of convenience in the creation and management of data in MongoDB."

You can now also define schema with mongoDB native driver using

##For new collection

`db.createCollection("recipes",
    validator: { $jsonSchema: {
         <<Validation Rules>>
        }
    }
)`

##For existing collection

`db.runCommand( {
        collMod: "recipes",
        validator: { $jsonSchema: {
             <<Validation Rules>>
            }
        }
    } )`
    

##full example

  validator: {
    $jsonSchema: {

Your encoded text is [B@6499375d. That is not Base64, something went wrong while encoding. That decoding code looks good.

Use this code to convert the byte[] to a String before adding it to the URL:

String encodedEmailString = new String(encodedEmail, "UTF-8");
// ...
String confirmLink = "Complete your registration by clicking on following"
    + "\n<a href='" + confirmationURL + encodedEmailString + "'>link</a>";

Well in order to understand how static and dynamic binding actually works? or how they are identified by compiler and JVM?

Let's take below example where Mammal is a parent class which has a method speak() and Human class extends Mammal, overrides the speak() method and then again overloads it with speak(String language).

public class OverridingInternalExample {

    private static class Mammal {
        public void speak() { System.out.println("ohlllalalalalalaoaoaoa"); }
    }

    private static class Human extends Mammal {

        @Override
        public void speak() { System.out.println("Hello"); }

        // Valid overload of speak
        public void speak(String language) {
            if (language.equals("Hindi")) System.out.println("Namaste");
            else System.out.println("Hello");
        }

        @Override
        public String toString() { return "Human Class"; }

    }

    //  Code below contains the output and bytecode of the method calls
    public static void main(String[] args) {
        Mammal anyMammal = new Mammal();
        anyMammal.speak();  // Output - ohlllalalalalalaoaoaoa
        // 10: invokevirtual #4 // Method org/programming/mitra/exercises/OverridingInternalExample$Mammal.speak:()V

        Mammal humanMammal = new Human();
        humanMammal.speak(); // Output - Hello
        // 23: invokevirtual #4 // Method org/programming/mitra/exercises/OverridingInternalExample$Mammal.speak:()V

        Human human = new Human();
        human.speak(); // Output - Hello
        // 36: invokevirtual #7 // Method org/programming/mitra/exercises/OverridingInternalExample$Human.speak:()V

        human.speak("Hindi"); // Output - Namaste
        // 42: invokevirtual #9 // Method org/programming/mitra/exercises/OverridingInternalExample$Human.speak:(Ljava/lang/String;)V
    }
}

When we compile the above code and try to look at the bytecode using javap -verbose OverridingInternalExample, we can see that compiler generates a constant table where it assigns integer codes to every method call and byte code for the program which I have extracted and included in the program itself (see the comments below every method call)

By looking at above code we can see that the bytecodes of humanMammal.speak(), human.speak() and human.speak("Hindi") are totally different (invokevirtual #4, invokevirtual #7, invokevirtual #9) because the compiler is able to differentiate between them based on the argument list and class reference. Because all of this get resolved at compile time statically that is why Method Overloading is known as Static Polymorphism or Static Binding.

But bytecode for anyMammal.speak() and humanMammal.speak() is same (invokevirtual #4) because according to compiler both methods are called on Mammal reference.

So now the question comes if both method calls have same bytecode then how does JVM know which method to call?

Well, the answer is hidden in the bytecode itself and it is invokevirtual instruction set. JVM uses the invokevirtual instruction to invoke Java equivalent of the C++ virtual methods. In C++ if we want to override one method in another class we need to declare it as virtual, But in Java, all methods are virtual by default because we can override every method in the child class (except private, final and static methods).

In Java, every reference variable holds two hidden pointers

1. A pointer to a table which again holds methods of the object and a pointer to the Class object. e.g. [speak(), speak(String) Class object]
2. A pointer to the memory allocated on the heap for that object’s data e.g. values of instance variables.

So all object references indirectly hold a reference to a table which holds all the method references of that object. Java has borrowed this concept from C++ and this table is known as virtual table (vtable).

A vtable is an array like structure which holds virtual method names and their references on array indices. JVM creates only one vtable per class when it loads the class into memory.

So whenever JVM encounter with a invokevirtual instruction set, it checks the vtable of that class for the method reference and invokes the specific method which in our case is the method from a object not the reference.

Because all of this get resolved at runtime only and at runtime JVM gets to know which method to invoke, that is why Method Overriding is known as Dynamic Polymorphism or simply Polymorphism or Dynamic Binding.

You can read it more details on my article How Does JVM Handle Method Overloading and Overriding Internally.

I don't think what your asking is possible.

Roll your own toFixed function: for positive values Math.floor works fine.

function toFixed(num, fixed) {
    fixed = fixed || 0;
    fixed = Math.pow(10, fixed);
    return Math.floor(num * fixed) / fixed;
}

For negative values Math.floor is round of the values. So you can use Math.ceil instead.

Example,

Math.ceil(-15.778665 * 10000) / 10000 = -15.7786
Math.floor(-15.778665 * 10000) / 10000 = -15.7787 // wrong.

I faced the same problem. I hope you have installed from here and have also done pip install pytesseract.

If everything is fine you should see that the path C:\Program Files (x86)\Tesseract-OCR where tesseract.exe is available.

Adding Path variable did not helped me, I actually added new variable with name tesseract in environment variables with a value of C:\Program Files (x86)\Tesseract-OCR\tesseract.exe.

Typing tesseract in the command line should now work as expected by giving you usage informations. You can now use pytesseract as such (don't forget to restart your python kernel before running this!):

import pytesseract
from PIL import Image

value=Image.open("text_image.png")
text = pytesseract.image_to_string(value, config='')    
print("text present in images:",text)

enjoy!

Yes, you can store and view images in Firebase. You can use a filepicker to get the image file. Then you can host the image however you want, I prefer Amazon s3. Once the image is hosted you can display the image using the URL generated for the image.

Hope this helps.

Since Java is a statically typed language, I would expect that a abs-method which takes an int returns an int, if it expects a float returns a float, for a Double, return a Double. Maybe it could return always the boxed or unboxed type for doubles and Doubles and so on.

So you need one method per type, but now you have a new problem: For byte, short, int, long the range for negative values is 1 bigger than for positive values.

So what should be returned for the method

byte abs (byte in) {
   // @todo
}

If the user calls abs on -128? You could always return the next bigger type so that the range is guaranteed to fit to all possible input values. This will lead to problems for long, where no normal bigger type exists, and make the user always cast the value down after testing - maybe a hassle.

The second option is to throw an arithmetic exception. This will prevent casting and checking the return type for situations where the input is known to be limited, such that X.MIN_VALUE can't happen. Think of MONTH, represented as int.

byte abs (byte in) throws ArithmeticException {
   if (in == Byte.MIN_VALUE) throw new ArithmeticException ("abs called on Byte.MIN_VALUE"); 
   return (in < 0) ? (byte) -in : in; 
}

The "let's ignore the rare cases of MIN_VALUE" habit is not an option. First make the code work - then make it fast. If the user needs a faster, but buggy solution, he should write it himself. The simplest solution that might work means: simple, but not too simple.

Since the code doesn't rely on state, the method can and should be made static. This allows for a quick test:

public static void main (String args []) {
    System.out.println (abs(new Byte ( "7")));
    System.out.println (abs(new Byte ("-7")));
    System.out.println (abs((byte)  7));
    System.out.println (abs((byte) -7));
    System.out.println (abs(new Byte ( "127")));
    try
    {
        System.out.println (abs(new Byte ("-128")));
    }
    catch (ArithmeticException ae)
    {
        System.out.println ("Integer: " + Math.abs (new Integer ("-128")));
    }
    System.out.println (abs((byte)  127));
    System.out.println (abs((byte) -128));
}

I catch the first exception and let it run into the second, just for demonstration.

There is a bad habit in programming, which is that programmers care much more for fast than for correct code. What a pity!

If you're curious why there is one more negative than positive value, I have a diagram for you.

If you don't care what the password policy is. You can set it to LOW by issuing below mysql command:

mysql> SET GLOBAL validate_password_policy=LOW;

function sample() {
    alert("This is sample function");
}

$(function() {
    $("#button").click(function() {
        setTimeout(sample, 2000);
    });

});

jsFiddle.

If you want to encapsulate sample() there, wrap the whole thing in a self invoking function (function() { ... })().

It's a conceptual problem.

Stringstream is a stream, so its iterators are forward, cannot return. In an output stringstream, you need a flush() to reinitialize it, as in any other output stream.

The test Resource files(src/test/resources) are loaded to target/test-classes sub folder. So we can use the below code to load the test resource files.

System.out.println(file.getAbsolutePath());

Note : Here the sample.txt file should be placed under src/test/resources folder.

After several month without real solution for this problem, I suppose that the best solution is to upgrade the application to .NET framework 4.0, which is supported by Windows 8, Windows 10 and Windows 2012 Server by default and it is still available as offline installation for Windows XP.

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

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

Firstly, see the different between absolute path and relative path here:

An absolute path always contains the root element and the complete directory list required to locate the file.

Alternatively, a relative path needs to be combined with another path in order to access a file.

In constructor File(String pathname), Javadoc's File class said that

A pathname, whether abstract or in string form, may be either absolute or relative.

If you want to get relative path, you must be define the path from the current working directory to file or directory.Try to use system properties to get this.As the pictures that you drew:

String localDir = System.getProperty("user.dir");
File file = new File(localDir + "\\config.properties");

Moreover, you should try to avoid using similar ".", "../", "/", and other similar relative to the file location relative path, because when files are moved, it is harder to handle.

As of version 0.11.0, columns can be sliced in the manner you tried using the .loc indexer:

df.loc[:, 'C':'E']

is equivalent to

df[['C', 'D', 'E']]  # or df.loc[:, ['C', 'D', 'E']]

and returns columns C through E.

A demo on a randomly generated DataFrame:

import pandas as pd
import numpy as np
np.random.seed(5)
df = pd.DataFrame(np.random.randint(100, size=(100, 6)),
                  columns=list('ABCDEF'),
                  index=['R{}'.format(i) for i in range(100)])
df.head()

Out:
     A   B   C   D   E   F
R0  99  78  61  16  73   8
R1  62  27  30  80   7  76
R2  15  53  80  27  44  77
R3  75  65  47  30  84  86
R4  18   9  41  62   1  82

To get the columns from C to E (note that unlike integer slicing, 'E' is included in the columns):

df.loc[:, 'C':'E']

Out:
      C   D   E
R0   61  16  73
R1   30  80   7
R2   80  27  44
R3   47  30  84
R4   41  62   1
R5    5  58   0
...

The same works for selecting rows based on labels. Get the rows 'R6' to 'R10' from those columns:

df.loc['R6':'R10', 'C':'E']

Out:
      C   D   E
R6   51  27  31
R7   83  19  18
R8   11  67  65
R9   78  27  29
R10   7  16  94

.loc also accepts a Boolean array so you can select the columns whose corresponding entry in the array is True. For example, df.columns.isin(list('BCD')) returns array([False, True, True, True, False, False], dtype=bool) - True if the column name is in the list ['B', 'C', 'D']; False, otherwise.

df.loc[:, df.columns.isin(list('BCD'))]

Out:
      B   C   D
R0   78  61  16
R1   27  30  80
R2   53  80  27
R3   65  47  30
R4    9  41  62
R5   78   5  58
...

From the matplotlib docs on scatter 1:

cmap is only used if c is an array of floats

So colorlist needs to be a list of floats rather than a list of tuples as you have it now. plt.colorbar() wants a mappable object, like the CircleCollection that plt.scatter() returns. vmin and vmax can then control the limits of your colorbar. Things outside vmin/vmax get the colors of the endpoints.

How does this work for you?

import matplotlib.pyplot as plt
cm = plt.cm.get_cmap('RdYlBu')
xy = range(20)
z = xy
sc = plt.scatter(xy, xy, c=z, vmin=0, vmax=20, s=35, cmap=cm)
plt.colorbar(sc)
plt.show()

ControllerBase: If wants to return data only go for ControllerBase class

If you changed the ruby version you're using with rvm use, remove Gemfile.lock and try again.

As a bare minimum:

tsconfig:

 "lib": [
      "es2015"
    ]

and install a polyfill such as https://github.com/zloirock/core-js if you want IE < 11 support: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map

It is a reference to the current file name. In the file foo.rb, __FILE__ would be interpreted as "foo.rb".

Edit: Ruby 1.9.2 and 1.9.3 appear to behave a little differently from what Luke Bayes said in his comment. With these files:

# test.rb
puts __FILE__
require './dir2/test.rb'

# dir2/test.rb
puts __FILE__

Running ruby test.rb will output

test.rb
/full/path/to/dir2/test.rb

Just place the colorbar in its own axis and use subplots_adjust to make room for it.

As a quick example:

import numpy as np
import matplotlib.pyplot as plt

fig, axes = plt.subplots(nrows=2, ncols=2)
for ax in axes.flat:
    im = ax.imshow(np.random.random((10,10)), vmin=0, vmax=1)

fig.subplots_adjust(right=0.8)
cbar_ax = fig.add_axes([0.85, 0.15, 0.05, 0.7])
fig.colorbar(im, cax=cbar_ax)

plt.show()

Note that the color range will be set by the last image plotted (that gave rise to im) even if the range of values is set by vmin and vmax. If another plot has, for example, a higher max value, points with higher values than the max of im will show in uniform color.

if you want to find datadir in linux or windows you can do following command

mysql -uUSER -p -e 'SHOW VARIABLES WHERE Variable_Name = "datadir"'

if you are interested to find datadir you can use grep & awk command

mysql -uUSER -p -e 'SHOW VARIABLES WHERE Variable_Name = "datadir"' | grep 'datadir' | awk '{print $2}'

The u in u'Some String' means that your string is a Unicode string.

Q: I'm in a terrible, awful hurry and I landed here from Google Search. I'm trying to write this data to a file, I'm getting an error, and I need the dead simplest, probably flawed, solution this second.

A: You should really read Joel's Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) essay on character sets.

Q: sry no time code pls

A: Fine. try str('Some String') or 'Some String'.encode('ascii', 'ignore'). But you should really read some of the answers and discussion on Converting a Unicode string and this excellent, excellent, primer on character encoding.

You can also look into using the Collection Object. This usually works better than an array for custom objects, since it dynamically sizes and has methods for:

• Add
• Count
• Remove
• Item(index)

Plus its normally easier to loop through a collection too since you can use the for...each structure very easily with a collection.

I agree that in most cases the if (!(x instanceof Y)) {...} is the best approach, but in some cases creating an isY(x) function so you can if (!isY(x)) {...} is worthwhile.

I'm a typescript novice, and I've bumped into this S/O question a bunch of times over the last few weeks, so for the googlers the typescript way to do this is to create a typeguard like this:

typeGuards.ts

export function isHTMLInputElement (value: any): value is HTMLInputElement {
  return value instanceof HTMLInputElement
}

usage

if (!isHTMLInputElement(x)) throw new RangeError()
// do something with an HTMLInputElement

I guess the only reason why this might be appropriate in typescript and not regular js is that typeguards are a common convention, so if you're writing them for other interfaces, it's reasonable / understandable / natural to write them for classes too.

There's more detail about user defined type guards like this in the docs

mkdirs() also creates parent directories in the path this File represents.

javadocs for mkdirs():

Creates the directory named by this abstract pathname, including any necessary but nonexistent parent directories. Note that if this operation fails it may have succeeded in creating some of the necessary parent directories.

javadocs for mkdir():

Creates the directory named by this abstract pathname.

Example:

File  f = new File("non_existing_dir/someDir");
System.out.println(f.mkdir());
System.out.println(f.mkdirs());

will yield false for the first [and no dir will be created], and true for the second, and you will have created non_existing_dir/someDir

        }
    }
   else if (checkBox2.Checked == true)

        foreach (DataGridViewRow row in dGV1.Rows)
        {
            DataGridViewCheckBoxCell chk = (DataGridViewCheckBoxCell)row.Cells[0];
            chk.Value = 1;
            if (row.IsNewRow)
            {
                chk.Value = 0;
            }
        }
    }
}

Explanation: Stash local changes including untracked changes (-u flag). The command saves your local modifications away and reverts the working directory to match the HEAD commit.

Want to recover the changes later?

git stash pop

Explanation: The command will reapply the changes to the top of the current working tree state.

Want to permanently remove the changes?

git stash drop

Explanation: The command will permanently remove the stashed entry

You should use the OO interface to matplotlib, rather than the state machine interface. Almost all of the plt.* function are thin wrappers that basically do gca().*.

plt.subplot returns an axes object. Once you have a reference to the axes object you can plot directly to it, change its limits, etc.

import matplotlib.pyplot as plt

ax1 = plt.subplot(131)
ax1.scatter([1, 2], [3, 4])
ax1.set_xlim([0, 5])
ax1.set_ylim([0, 5])


ax2 = plt.subplot(132)
ax2.scatter([1, 2],[3, 4])
ax2.set_xlim([0, 5])
ax2.set_ylim([0, 5])

and so on for as many axes as you want.

or better, wrap it all up in a loop:

import matplotlib.pyplot as plt

DATA_x = ([1, 2],
          [2, 3],
          [3, 4])

DATA_y = DATA_x[::-1]

XLIMS = [[0, 10]] * 3
YLIMS = [[0, 10]] * 3

for j, (x, y, xlim, ylim) in enumerate(zip(DATA_x, DATA_y, XLIMS, YLIMS)):
    ax = plt.subplot(1, 3, j + 1)
    ax.scatter(x, y)
    ax.set_xlim(xlim)
    ax.set_ylim(ylim)

I ended up changing how the MasterType is referenced in the page mark up.

I changed: <%@ MasterType VirtualPath="~/x/y/MyMaster.Master" %> to <%@ MasterType TypeName="FullyQualifiedNamespace.MyMaster" %>

See here for details.

Hope this helps someone out.

I know this is an old question, but it still comes up in the top searches for this issue so I'm adding a new answer to help those looking for one for IE:

Adding &wmode=opaque to the end of the URL does NOT work in IE 10...

However, adding ?wmode=opaque does the trick!

Found this solution here: http://alamoxie.com/blog/web-design/stop-iframes-covering-site-elements

For me this error occured after installing of gcloud component app-engine-python in order to integrate into pycharm. Uninstalling the module helped, even if pycharm is now not uploading to app-engine.

The Excel number for a modern date is most easily calculated as the number of days since 12/30/1899 on the Gregorian calendar.

Excel treats the mythical date 01/00/1900 (i.e., 12/31/1899) as corresponding to 0, and incorrectly treats year 1900 as a leap year. So for dates before 03/01/1900, the Excel number is effectively the number of days after 12/31/1899.

However, Excel will not format any number below 0 (-1 gives you ##########) and so this only matters for "01/00/1900" to 02/28/1900, making it easier to just use the 12/30/1899 date as a base.

A complete function in DB2 SQL that accounts for the leap year 1900 error:

SELECT
   DAYS(INPUT_DATE)                 
   - DAYS(DATE('1899-12-30'))
   - CASE                       
        WHEN INPUT_DATE < DATE('1900-03-01')  
           THEN 1               
           ELSE 0               
     END

You could also use the following, as of C# 6.0

string myString = null;
string result = myString?.ToUpper();

The string result will be null.

The way I do it is:

• Always put the join conditions in the ON clause if you are doing an INNER JOIN. So, do not add any WHERE conditions to the ON clause, put them in the WHERE clause.

• If you are doing a LEFT JOIN, add any WHERE conditions to the ON clause for the table in the right side of the join. This is a must, because adding a WHERE clause that references the right side of the join will convert the join to an INNER JOIN.

  The exception is when you are looking for the records that are not in a particular table. You would add the reference to a unique identifier (that is not ever NULL) in the RIGHT JOIN table to the WHERE clause this way: WHERE t2.idfield IS NULL. So, the only time you should reference a table on the right side of the join is to find those records which are not in the table.

I have had good experiences with Rational Purify. I have also heard nice things about Valgrind

Code which disable chrome extensions for ones, who uses DesiredCapabilities to set browser flags :

desired_capabilities['chromeOptions'] = {
    "args": ["--disable-extensions"],
    "extensions": []
}
webdriver.Chrome(desired_capabilities=desired_capabilities)

SCREEN:

NOTE: screen is actually not able to send hex, as far as I know. To do that, use echo or printf

I was using the suggestions in this post to write to a serial port, then using the info from another post to read from the port, with mixed results. I found that using screen is an "easier" solution, since it opens a terminal session directly with that port. (I put easier in quotes, because screen has a really weird interface, IMO, and takes some further reading to figure it out.)

You can issue this command to open a screen session, then anything you type will be sent to the port, plus the return values will be printed below it:

screen /dev/ttyS0 19200,cs8

(Change the above to fit your needs for speed, parity, stop bits, etc.) I realize screen isn't the "linux command line" as the post specifically asks for, but I think it's in the same spirit. Plus, you don't have to type echo and quotes every time.

ECHO:

Follow praetorian droid's answer. HOWEVER, this didn't work for me until I also used the cat command (cat < /dev/ttyS0) while I was sending the echo command.

PRINTF:

I found that one can also use printf's '%x' command:

c="\x"$(printf '%x' 0x12)
printf $c >> $SERIAL_COMM_PORT

Again, for printf, start cat < /dev/ttyS0 before sending the command.

from a table?

You can use this if you have no foreign keys to other tables

truncate table TableName

or

delete TableName

if you want all tables

sp_msforeachtable 'delete ?'

You state in the comments that the returned JSON is this:

{ 
  "dstOffset" : 3600, 
  "rawOffset" : 36000, 
  "status" : "OK", 
  "timeZoneId" : "Australia/Hobart", 
  "timeZoneName" : "Australian Eastern Daylight Time" 
}

You're telling Gson that you have an array of Post objects:

List<Post> postsList = Arrays.asList(gson.fromJson(reader,
                    Post[].class));

You don't. The JSON represents exactly one Post object, and Gson is telling you that.

Change your code to be:

Post post = gson.fromJson(reader, Post.class);

$ ionic -v

CLI 4.12.0

I didn't particularly like any of the answers.

Here is how I did it.

# Convert the file into an array of strings
lines=(`cat "foo.txt"`)

# Print out the lines via array index
echo "${lines[0]}"
echo "${lines[1]}"
echo "${lines[5]}"

It is because your system has two installations of "mysql" packages. One installation was made through xampp/lampp and another installation was made through mysql-debain package. To solve the problem, just go to "synaptic manager" and remove mysql, and then you will be able to access mysql from xampp server.

Note : removing mysql from synaptic manager doesn't affect mysql which was installed through xampp/lampp server. So don't worry!

DES is the old "data encryption standard" from the seventies.

oninput="this.value=(this.value   < Number(this.min) || this.value   > Number(this.max))  ? '' : this.value;"

Use is simple:

convert(date, Btch_Time)

Example below:

Table:

Select * from helios.dbo.CBA_SRD_Loan where Loan_I in ('200312500') and convert(date, Btch_Time) = '2014-06-17'

From The Definitive Guide to Django: Web Development Done Right:

If you’ve used Python before, you may be wondering why we’re running python manage.py shell instead of just python. Both commands will start the interactive interpreter, but the manage.py shell command has one key difference: before starting the interpreter, it tells Django which settings file to use.

Use Case: Many parts of Django, including the template system, rely on your settings, and you won’t be able to use them unless the framework knows which settings to use.

If you’re curious, here’s how it works behind the scenes. Django looks for an environment variable called DJANGO_SETTINGS_MODULE, which should be set to the import path of your settings.py. For example, DJANGO_SETTINGS_MODULE might be set to 'mysite.settings', assuming mysite is on your Python path.

When you run python manage.py shell, the command takes care of setting DJANGO_SETTINGS_MODULE for you.**

The std::string object returned by ss.str() is a temporary object that will have a life time limited to the expression. So you cannot assign a pointer to a temporary object without getting trash.

Now, there is one exception: if you use a const reference to get the temporary object, it is legal to use it for a wider life time. For example you should do:

#include <string>
#include <sstream>
#include <iostream>

using namespace std;

int main()
{
    stringstream ss("this is a string\n");

    string str(ss.str());

    const char* cstr1 = str.c_str();

    const std::string& resultstr = ss.str();
    const char* cstr2 = resultstr.c_str();

    cout << cstr1       // Prints correctly
        << cstr2;       // No more error : cstr2 points to resultstr memory that is still alive as we used the const reference to keep it for a time.

    system("PAUSE");

    return 0;
}

That way you get the string for a longer time.

Now, you have to know that there is a kind of optimisation called RVO that say that if the compiler see an initialization via a function call and that function return a temporary, it will not do the copy but just make the assigned value be the temporary. That way you don't need to actually use a reference, it's only if you want to be sure that it will not copy that it's necessary. So doing:

 std::string resultstr = ss.str();
 const char* cstr2 = resultstr.c_str();

would be better and simpler.

Since you are using C++11, lambda-expression is a nice&clean solution.

class blub {
    void test() {}
  public:
    std::thread spawn() {
      return std::thread( [this] { this->test(); } );
    }
};

since this-> can be omitted, it could be shorten to:

std::thread( [this] { test(); } )

or just (deprecated)

std::thread( [=] { test(); } )

This problem occurs when the controller or directive are not specified as a array of dependencies and function. For example

angular.module("appName").directive('directiveName', function () {
    return {
        restrict: 'AE',
        templateUrl: 'calender.html',
        controller: function ($scope) {
            $scope.selectThisOption = function () {
                // some code
            };
        }
    };
});

When minified The '$scope' passed to the controller function is replaced by a single letter variable name . This will render angular clueless of the dependency . To avoid this pass the dependency name along with the function as a array.

angular.module("appName").directive('directiveName', function () {
    return {
        restrict: 'AE',
        templateUrl: 'calender.html'
        controller: ['$scope', function ($scope) { //<-- difference
            $scope.selectThisOption = function () {
                // some code
            };
        }]
    };
});

Unfortunately, this does not work on macOS. Despite the fact that I have export CONDA_DEFAULT_ENV='$HOME/anaconda3/envs/dev' in my .zshrc and "python.pythonPath": "${env.CONDA_DEFAULT_ENV}/bin/python", in my VSCode prefs, the built-in terminal does not use that environment's Python, even if I have started VSCode from the command line where that variable is set.

This is an old question, but it has no chosen answer, and I just solved this problem myself. Here's my solution:

1. Make sure you are set up to work with your Google API in the first place. See Google's list of prerequisites. I was working with Google My Business, so I also went through it's Get Started process.

2. In the OAuth 2.0 playground, Step 1 requires you to select which API you want to authenticate. Select or input as applicable for your case (in my case for Google My Business, I had to input https://www.googleapis.com/auth/plus.business.manage into the "Input your own scopes" input field). Note: this is the same as what's described in step 6 of the "Make a simple HTTP request" section of the Get Started guide.

3. Assuming successful authentication, you should get an "Access token" returned in the "Step 1's result" step in the OAuth playground. Copy this token to your clipboard.

4. Open Postman and open whichever collection you want as necessary.

5. In Postman, make sure "GET" is selected as the request type, and click on the "Authorization" tab below the request type drop-down.

6. In the Authorization "TYPE" dropdown menu, select "Bearer Token"

7. Paste your previously copied "Access Token" which you copied from the OAuth playground into the "Token" field which displays in Postman.

8. Almost there! To test if things work, put https://mybusiness.googleapis.com/v4/accounts/ into the main URL input bar in Postman and click the send button. You should get a JSON list of accounts back in the response that looks something like the following:

   
   {
       "accounts": [
           {
               "name": "accounts/REDACTED",
               "accountName": "REDACTED",
               "type": "PERSONAL",
               "state": {
                   "status": "UNVERIFIED"
               }
           },
           {
               "name": "accounts/REDACTED",
               "accountName": "REDACTED",
               "type": "LOCATION_GROUP",
               "role": "OWNER",
               "state": {
                   "status": "UNVERIFIED"
               },
               "permissionLevel": "OWNER_LEVEL"
           }
       ]
   }
   

QRGen is a good library that creates a layer on top of ZXing and makes QR Code generation in Java a piece of cake.

target="_parent" worked great for me. easy and hassle free!

The below query will work fine as per your question.

SELECT M1.* 
FROM MESSAGES M1,
(
 SELECT SUBSTR(Others_data,1,2),MAX(Others_data) AS Max_Others_data
 FROM MESSAGES
 GROUP BY 1
) M2
WHERE M1.Others_data = M2.Max_Others_data
ORDER BY Others_data;

I use this JS snippet code :

First of all, I reach all the classes then according to index of my target class, I set className = "".

Target = document.getElementsByClassName("yourClass")[1];
Target.className="";

Datetime is a datatype.

Timestamp is a method for row versioning. In fact, in sql server 2008 this column type was renamed (i.e. timestamp is deprecated) to rowversion. It basically means that every time a row is changed, this value is increased. This is done with a database counter which automatically increase for every inserted or updated row.

For more information:

Many 3rd party JavaScript libraries allow you to select all elements that have a CSS class of a particular name applied to them. Then you can iterate those elements and dynamically attach the handler.

There is no CSS-specific manner to do this.

In JQuery, you can do:

$(".myCssClass").click(function() { alert("hohoho"); });

def merge_with(f, xs, ys):
    xs = a_copy_of(xs) # dict(xs), maybe generalizable?
    for (y, v) in ys.iteritems():
        xs[y] = v if y not in xs else f(xs[x], v)

merge_with((lambda x, y: x + y), A, B)

You could easily generalize this:

def merge_dicts(f, *dicts):
    result = {}
    for d in dicts:
        for (k, v) in d.iteritems():
            result[k] = v if k not in result else f(result[k], v)

Then it can take any number of dicts.

The browser's native JSON API may not give you back your idOld function after you call JSON.stringify, however, if can stringify your JSON yourself (maybe use Crockford's json2.js instead of browser's API), then if you have a string of JSON e.g.

var person_json = "{ \"age:\" : 20, \"isOld:\": false, isOld: function() { return this.age > 60; } }";

then you can call

eval("(" + person + ")") 

, and you will get back your function in the json object.

The snippet here works fine, tested with windows sound:

public static void main(String[] args) {
        AePlayWave aw = new AePlayWave( "C:\\WINDOWS\\Media\\tada.wav" );
        aw.start();     
}

#Reading the Host,username,password,port from excel file

ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

loc = ('/Users/harshgow/Documents/PYTHON_WORK/labcred.xlsx')
wo = xlrd.open_workbook(loc)
sheet = wo.sheet_by_index(0)
Host = sheet.cell_value(0,1)
Port = int(sheet.cell_value(3,1))
User = sheet.cell_value(1,1)
Pass = sheet.cell_value(2,1)

def details(Host,Port,User,Pass):
    ssh.connect(Host, Port, User, Pass)
    print('connected to ip ',Host)
    stdin, stdout, stderr = ssh.exec_command("")
    stdin.write('xcommand SystemUnit Boot Action: Restart\n')
    print('success')

details(Host,Port,User,Pass)

The client machine needs a proper font that has a glyph for this character to display it. But Times New Roman doesn’t. Try Arial Unicode MS or Lucida Grande instead:

<span style="font-family: Arial Unicode MS, Lucida Grande">
    &#10003; &#10004;
</span>

This works for me on Windows XP in IE 5.5, IE 6.0, FF 3.0.6.

In order for sudo to work the way everyone suggest, you need to be in the admin group.

You should implement a Comparator<Map<String, String>> which basically extracts the "name" value from the two maps it's passed, and compares them.

Then use Collections.sort(list, comparator).

Are you sure a Map<String, String> is really the best element type for your list though? Perhaps you should have another class which contains a Map<String, String> but also has a getName() method?

you need to wrap your text inside div and float it left while wrapper div should have height, and I've also added line height for vertical alignment

<div style="border-bottom-width: 1px; border-bottom-style: solid; border-bottom-color: gray;height:30px;">
   <div style="float:left;line-height:30px;">Contact Details</div>

    <button type="button" class="edit_button" style="float: right;">My Button</button>

</div>

Pipe it to awk:

awk '{if(NR>1)print}'

or sed

sed -n '1!p'

var a = ["one", "two", "three", "four", "five"]

// Remove/filter item with value 'three'
a = a.filter { $0 != "three" }

SHOW TABLES LIKE 'TableName'

If you have ANY results, the table exists.

To use this approach in PDO:

$pdo         = new \PDO(/*...*/);
$result      = $pdo->query("SHOW TABLES LIKE 'tableName'");
$tableExists = $result !== false && $result->rowCount() > 0;

To use this approach with DEPRECATED mysql_query

$result      = mysql_query("SHOW TABLES LIKE 'tableName'");
$tableExists = mysql_num_rows($result) > 0;

You need this instead:

if(s.contains("+"))

contains() method of String class does not take regular expression as a parameter, it takes normal text.

EDIT:

String s = "ddjdjdj+kfkfkf";

if(s.contains("+"))
{
    String parts[] = s.split("\\+");
    System.out.print(parts[0]);
}

OUTPUT:

ddjdjdj

EDIT 2019-07-26

#troubleshooting-locally-in-a-docker-image section is no longer part of the docs; here's why

  • https://blog.travis-ci.com/2018-11-30-announcing-xenial-build-environment-for-enterprise

Though, it's still in git history: https://github.com/travis-ci/docs-travis-ci-com/pull/2193.

Look for (quite old, couldn't find newer) image versions at: https://travis-ci.org/travis-ci/docs-travis-ci-com/builds/230889063#L661.

I wanted to inspect why one of the tests in my build failed with an error I din't get locally.

Worked.

What actually worked was using the image specified at Troubleshooting Locally in a Docker Image docs page. In my case it was travisci/ci-garnet:packer-1512502276-986baf0.

I was able to add travise compile following steps described at https://github.com/travis-ci/travis-build#use-as-addon-for-travis-cli.

Definitely not Trusty (Ubuntu 14.04) and not small either.

Using this,

        String s = "03/24/2013 21:54";
        SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MM/dd/yyyy HH:mm");
        try
        {
            Date date = simpleDateFormat.parse(s);

            System.out.println("date : "+simpleDateFormat.format(date));
        }
        catch (ParseException ex)
        {
            System.out.println("Exception "+ex);
        }

Muhammad Musavi's comment is the best answer, so here it is surfaced as an actual Answer:

thead/tfoot are automatically repeated on the top and bottom of each page. However, tfoot isn't sticky to the bottom of the last page.

position: fixed in print will repeat on each page, and the footer will stick to the bottom of all pages including the last one - but, it won't create space for its contents.

Combine them:

HTML:

<header>(repeated header)</header>

<table class=paging><thead><tr><td>&nbsp;</td></tr></thead><tbody><tr><td>

(content goes here)

</td></tr></tbody><tfoot><tr><td>&nbsp;</td></tr></tfoot></table>

<footer>(repeated footer)</footer>

CSS:

@page {
    size: letter;
    margin: .5in;
}

@media print {
    table.paging thead td, table.paging tfoot td {
        height: .5in;
    }
}

header, footer {
    width: 100%; height: .5in;
}

header {
    position: absolute;
    top: 0;
}

@media print {
    header, footer {
        position: fixed;
    }
    
    footer {
        bottom: 0;
    }
}

There are a lot of niceties you can add in here, but I've intentionally slashed this to the bare minimum to get a cleanly rendering header and footer, appearing once on-screen and at the top and bottom of every printed page.

Try this. Maybe it will work for you:

<html>
<head>
<script type="text/javascript">
    var i, j;
    //outer loop
    for(i = 0;i < 5; i++){
      //inner loop
      for(j = 0;j <= i; j++){
        document.write('*');
      }
      document.write('<br/>');
   }
</script>
</head>
<body>
</body>
</html>

For example in my case I accidentaly changed role of some users to incorrect, and my application got error during starting (NullReferenceException). When I fixed it - the app starts fine.

If you need a solution anyway (e.g. because you have too many implementations of the abstract class and the testing would always repeat the same procedures) then you could create an abstract test class with an abstract factory method which will be excuted by the implementation of that test class. This examples works or me with TestNG:

The abstract test class of Car:

abstract class CarTest {

// the factory method
abstract Car createCar(int speed, int fuel);

// all test methods need to make use of the factory method to create the instance of a car
@Test
public void testGetSpeed() {
    Car car = createCar(33, 44);
    assertEquals(car.getSpeed(), 33);
    ...

Implementation of Car

class ElectricCar extends Car {

    private final int batteryCapacity;

    public ElectricCar(int speed, int fuel, int batteryCapacity) {
        super(speed, fuel);
        this.batteryCapacity = batteryCapacity;
    }

    ...

Unit test class ElectricCarTest of the Class ElectricCar:

class ElectricCarTest extends CarTest {

    // implementation of the abstract factory method
    Car createCar(int speed, int fuel) {
        return new ElectricCar(speed, fuel, 0);
    }

    // here you cann add specific test methods
    ...

Have you tried setting the selection properties of your tableView like this:

tableView.allowsMultipleSelection = NO; tableView.allowsMultipleSelectionDuringEditing = YES; tableView.allowsSelection = NO; tableView.allowsSelectionDuringEditing YES; 

If you want more fine-grain control over when selection is allowed you can override - (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath in your UITableView delegate. The documentation states:

Return Value An index-path object that confirms or alters the selected row. Return an NSIndexPath object other than indexPath if you want another cell to be selected. Return nil if you don't want the row selected. 

You can have this method return nil in cases where you don't want the selection to happen.

First of all, you can't pass to alert second argument, use concatenation instead

alert("Input is " + inputValue);

Example

However in order to get values from input better to use states like this

var MyComponent = React.createClass({_x000D_
  getInitialState: function () {_x000D_
    return { input: '' };_x000D_
  },_x000D_
_x000D_
  handleChange: function(e) {_x000D_
    this.setState({ input: e.target.value });_x000D_
  },_x000D_
_x000D_
  handleClick: function() {_x000D_
    console.log(this.state.input);_x000D_
  },_x000D_
_x000D_
  render: function() {_x000D_
    return (_x000D_
      <div>_x000D_
        <input type="text" onChange={ this.handleChange } />_x000D_
        <input_x000D_
          type="button"_x000D_
          value="Alert the text input"_x000D_
          onClick={this.handleClick}_x000D_
        />_x000D_
      </div>_x000D_
    );_x000D_
  }_x000D_
});_x000D_
_x000D_
ReactDOM.render(_x000D_
  <MyComponent />,_x000D_
  document.getElementById('container')_x000D_
);

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>_x000D_
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>_x000D_
<div id="container"></div>

Just use two Listboxes, one for header and other for data

1. for headers - set RowSource property to top row e.g. Incidents!Q4:S4

2. for data - set Row Source Property to Incidents!Q5:S10

SpecialEffects to "3-frmSpecialEffectsEtched"

Try this CSS:

body {
  margin: 0;
  padding: 0;
}

.logo {
  float: left;
}
/* ~~ Top Navigation Bar ~~ */

#navigation-container {
  width: 1200px;
  margin: 0 auto;
  height: 70px;
}

.navigation-bar {
  background-color: #352d2f;
  height: 70px;
  width: 100%;
}

#navigation-container img {
  float: left;
}

#navigation-container ul {
  padding: 0px;
  margin: 0px;
  text-align: center;
  display:inline-block;
}

#navigation-container li {
  list-style-type: none;
  padding: 0px;
  height: 24px;
  margin-top: 4px;
  margin-bottom: 4px;
  display: inline;
}

#navigation-container li a {
  color: white;
  font-size: 16px;
  font-family: "Trebuchet MS", Arial, Helvetica, sans-serif;
  text-decoration: none;
  line-height: 70px;
  padding: 5px 15px;
  opacity: 0.7;
}

#menu {
  float: right;
}

mv in unix-ish systems, move in dos/windows.

e.g.

C:\> move c:\users\you\somefile.txt   c:\temp\newlocation.txt

and

$ mv /home/you/somefile.txt /tmp/newlocation.txt

Here's an extension method using @Kolman's answer. It's marginally easier to remember to use Path() than GetLeftPart. You might want to rename Path to GetPath, at least until they add extension properties to C#.

Usage:

Uri uri = new Uri("http://www.somewhere.com?param1=foo&param2=bar");
string path = uri.Path();

The class:

using System;

namespace YourProject.Extensions
{
    public static class UriExtensions
    {
        public static string Path(this Uri uri)
        {
            if (uri == null)
            {
                throw new ArgumentNullException("uri");
            }
            return uri.GetLeftPart(UriPartial.Path);
        }
    }
}

No need for jQuery

JavaScript does have a native .trim() method.

var name = "    John Smith  ";
name = name.trim();

console.log(name); // "John Smith"

Example Here

String.prototype.trim()

The trim() method removes whitespace from both ends of a string. Whitespace in this context is all the whitespace characters (space, tab, no-break space, etc.) and all the line terminator characters (LF, CR, etc.).

Do this to use a profile with name 'dev':

session = boto3.session.Session(profile_name='dev')
s3 = session.resource('s3')
for bucket in s3.buckets.all():
    print(bucket.name)

SHOW CREATE TABLE yourTable;

or

SHOW COLUMNS FROM yourTable;
