I fork @Ludwig code and remove necessity of swfobject.

I just use swfobject code for detect flash version.

its work for me set the User-Agent in the addRequestProperty.

URL url = new URL(<URL>);
HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();
httpConn.addRequestProperty("User-Agent","Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:56.0) Gecko/20100101 Firefox/56.0");

fixed my agent string evaluation by scrubbing the string for LOWERCASE "iphone os 5_0" as opposed to "iPhone OS 5_0." now i am properly assigning iOS 5 specific classes to my html, when the uppercase scrub failed.

iPhone:

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

iPad:

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

For a complete list and more details about the iOS user agent check out these 2 resources:
Safari User Agent Strings (http://useragentstring.com/pages/Safari/)
Complete List of iOS User-Agent Strings (http://enterpriseios.com/wiki/UserAgent)

headers = { 'User-Agent' : 'Mozilla/5.0' }
req = urllib2.Request('www.example.com', None, headers)
html = urllib2.urlopen(req).read()

Or, a bit shorter:

req = urllib2.Request('www.example.com', headers={ 'User-Agent': 'Mozilla/5.0' })
html = urllib2.urlopen(req).read()

You can look for this information in $_SERVER['HTTP_USER_AGENT'], but its format is free-form, not guaranteed to be sent, and could easily be altered by the user, whether for privacy or other reasons.

If you've not set the browsecap directive, this will return a warning. To make sure it's set, you can retrieve the value using ini_get and see if it's set.

if(ini_get("browscap")) {
    $browser = get_browser(null, true);
    $browser = get_browser($_SERVER['HTTP_USER_AGENT']);  
} 

As kba explained in his answer, your browser sends a lot of information to the server while loading a webpage. Most websites use these User-agent information to determine the visitor's operating system, browser and various information.

Using JQuery:

http://tanalin.com/en/articles/ie-version-js/

Using C#:

var browser = Request.Browser.Browser;

Try doing this, using firefox as fake user agent (moreover, it's a good startup script for web scraping with the use of cookies):

#!/usr/bin/env python2
# -*- coding: utf8 -*-
# vim:ts=4:sw=4


import cookielib, urllib2, sys

def doIt(uri):
    cj = cookielib.CookieJar()
    opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(cj))
    page = opener.open(uri)
    page.addheaders = [('User-agent', 'Mozilla/5.0')]
    print page.read()

for i in sys.argv[1:]:
    doIt(i)

USAGE:

python script.py "http://www.ichangtou.com/#company:data_000008.html"

You need to set both the user-agent and the referer:

 wget  --header="Accept: text/html" --user-agent="Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:21.0) Gecko/20100101 Firefox/21.0" --referrer  connect.wso2.com http://dist.wso2.org/products/carbon/4.2.0/wso2carbon-4.2.0.zip

The user agent string is a text that the browsers themselves send to the webserver to identify themselves, so that websites can send different content based on the browser or based on browser compatibility.

Mozilla is a browser rendering engine (the one at the core of Firefox) and the fact that Chrome and IE contain the string Mozilla/4 or /5 identifies them as being compatible with that rendering engine.

There are no HTTP headers that will report the clients timezone so far although it has been suggested to include it in the HTTP specification.

If it was me, I would probably try to fetch the timezone using clientside JavaScript and then submit it to the server using Ajax or something.

If you need to set the user header string in the curl request, you can use the -H option to set user agent like:

curl -H "user-agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/88.0.4324.182 Safari/537.36" http://stackoverflow.com/questions/28760694/how-to-use-curl-to-get-a-get-request-exactly-same-as-using-chrome

Updated user-agent form newest Chrome at 02-22-2021

Using a proxy tool like Charles Proxy really helps make short work of something like what you are asking. Here is what I do, using this SO page as an example (as of July 2015 using Charles version 3.10):

1. Get Charles Proxy running
2. Make web request using browser
3. Find desired request in Charles Proxy
4. Right click on request in Charles Proxy
5. Select 'Copy cURL Request'

You now have a cURL request you can run in a terminal that will mirror the request your browser made. Here is what my request to this page looked like (with the cookie header removed):

curl -H "Host: stackoverflow.com" -H "Cache-Control: max-age=0" -H "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8" -H "User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/44.0.2403.89 Safari/537.36" -H "HTTPS: 1" -H "DNT: 1" -H "Referer: https://www.google.com/" -H "Accept-Language: en-US,en;q=0.8,en-GB;q=0.6,es;q=0.4" -H "If-Modified-Since: Thu, 23 Jul 2015 20:31:28 GMT" --compressed http://stackoverflow.com/questions/28760694/how-to-use-curl-to-get-a-get-request-exactly-same-as-using-chrome

To build on JJC's helpful answer that builds on Louis's helpful answer...

With PhantomJS 2.1.1-windows this line works:

driver.execute_script("return navigator.userAgent")

If it doesn't work, you can still get the user agent via the log (to build on Mma's answer):

from selenium import webdriver
import json
from fake_useragent import UserAgent

dcap = dict(DesiredCapabilities.PHANTOMJS)
dcap["phantomjs.page.settings.userAgent"] = (UserAgent().random)
driver = webdriver.PhantomJS(executable_path=r"your_path", desired_capabilities=dcap)
har = json.loads(driver.get_log('har')[0]['message']) # get the log
print('user agent: ', har['log']['entries'][0]['request']['headers'][1]['value'])

Yes user-agent is used to detect mobile browsers. There are lots of free scripts available to check this. Here is one such php code which will help you redirect mobile users to different website.

You could also use the php native funcion get_browser()

IMPORTANT NOTE: You should have a browscap.ini file.

I did want to obmit a old big history and start from a fresh commit i choosed to:

rsync -a --exclude '.git' old-repo/ new-repo/
cd new-repo 
git push 

when now old-repo changes i can apply the patches to the new-repo to rebase them on the new-repo.

It's possible, you can simply use jQuery to substitute the 'meta tag' that references the cache status with an event handler / button, and then refresh, easy,

$('.button').click(function() {
    $.ajax({
        url: "",
        context: document.body,
        success: function(s,x){

            $('html[manifest=saveappoffline.appcache]').attr('content', '');
                $(this).html(s);
        }
    }); 
});

NOTE: This solution relies on the Application Cache that is implemented as part of the HTML 5 spec. It also requires server configuration to set up the App Cache manifest. It does not describe a method by which one can clear the 'traditional' browser cache via client- or server-side code, which is nigh impossible to do.

list comprehension formula:

[<value_when_condition_true> if <condition> else <value_when_condition_false> for value in list_name]

thus you can do it like this:

[y for y in a if y not in b]

Only for demonstration purpose : [y if y not in b else False for y in a ]

This function will return you image with black border try this.. hope this will help you

- (UIImage *)addBorderToImage:(UIImage *)image frameImage:(UIImage *)blackBorderImage
{
    CGSize size = CGSizeMake(image.size.width,image.size.height);
    UIGraphicsBeginImageContext(size);

    CGPoint thumbPoint = CGPointMake(0,0);

    [image drawAtPoint:thumbPoint];


    UIGraphicsBeginImageContext(size);
    CGImageRef imgRef = blackBorderImage.CGImage;
    CGContextDrawImage(UIGraphicsGetCurrentContext(), CGRectMake(0, 0, size.width,size.height), imgRef);
    UIImage *imageCopy = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    CGPoint starredPoint = CGPointMake(0, 0);
    [imageCopy drawAtPoint:starredPoint];
    UIImage *imageC = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return imageC;
}

If all you want is the time between two points in code (and it seems that's what you want) I have written tic() toc() functions ala Matlab's implementation. The basic use case is:

tic()

''' some code that runs for an interesting amount of time '''

toc()

# OUTPUT:
# Elapsed time is: 32.42123 seconds

Super, incredibly easy to use, a sort of fire-and-forget kind of code. It's available on Github's Gist https://gist.github.com/tyleha/5174230

For me - the folder from which the service was to run, and the files in it, were encrypted using the Windows "Encrypt" option. Removing that and - voila!

I'm surprised no one has suggested using a result filter. This is the cleanest way to globally hook into the action/result pipeline:

public class JsonResultFilter : IResultFilter
{
    public int? MaxJsonLength { get; set; }

    public int? RecursionLimit { get; set; }

    public void OnResultExecuting(ResultExecutingContext filterContext)
    {
        if (filterContext.Result is JsonResult jsonResult)
        {
            // override properties only if they're not set
            jsonResult.MaxJsonLength = jsonResult.MaxJsonLength ?? MaxJsonLength;
            jsonResult.RecursionLimit = jsonResult.RecursionLimit ?? RecursionLimit;
        }
    }

    public void OnResultExecuted(ResultExecutedContext filterContext)
    {
    }
}

Then, register an instance of that class using GlobalFilters.Filters:

GlobalFilters.Filters.Add(new JsonResultFilter { MaxJsonLength = int.MaxValue });

In case you need to do that from the command line, just copy, adapt & paste this snippet:

mysql -e "CREATE DATABASE \`new_database\`;"
for table in `mysql -B -N -e "SHOW TABLES;" old_database`
do 
  mysql -e "RENAME TABLE \`old_database\`.\`$table\` to \`new_database\`.\`$table\`"
done
mysql -e "DROP DATABASE \`old_database\`;"

Sys.sleep() will not work if the CPU usage is very high; as in other critical high priority processes are running (in parallel).

This code worked for me. Here I am printing 1 to 1000 at a 2.5 second interval.

for (i in 1:1000)
{
  print(i)
  date_time<-Sys.time()
  while((as.numeric(Sys.time()) - as.numeric(date_time))<2.5){} #dummy while loop
}

This is one way to do it:

SQL> set serveroutput on
SQL> CREATE OR REPLACE TYPE MyType AS VARRAY(200) OF VARCHAR2(50);
  2  /

Type created

SQL> CREATE OR REPLACE PROCEDURE testing (t_in MyType) IS
  2  BEGIN
  3    FOR i IN 1..t_in.count LOOP
  4      dbms_output.put_line(t_in(i));
  5    END LOOP;
  6  END;
  7  /

Procedure created

SQL> DECLARE
  2    v_t MyType;
  3  BEGIN
  4    v_t := MyType();
  5    v_t.EXTEND(10);
  6    v_t(1) := 'this is a test';
  7    v_t(2) := 'A second test line';
  8    testing(v_t);
  9  END;
 10  /

this is a test
A second test line

To expand on my comment to @dcp's answer, here's how you could implement the solution proposed there if you wanted to use an associative array:

SQL> CREATE OR REPLACE PACKAGE p IS
  2    TYPE p_type IS TABLE OF VARCHAR2(50) INDEX BY BINARY_INTEGER;
  3  
  4    PROCEDURE pp (inp p_type);
  5  END p;
  6  /

Package created
SQL> CREATE OR REPLACE PACKAGE BODY p IS
  2    PROCEDURE pp (inp p_type) IS
  3    BEGIN
  4      FOR i IN 1..inp.count LOOP
  5        dbms_output.put_line(inp(i));
  6      END LOOP;
  7    END pp;
  8  END p;
  9  /

Package body created
SQL> DECLARE
  2    v_t p.p_type;
  3  BEGIN
  4    v_t(1) := 'this is a test of p';
  5    v_t(2) := 'A second test line for p';
  6    p.pp(v_t);
  7  END;
  8  /

this is a test of p
A second test line for p

PL/SQL procedure successfully completed

This trades creating a standalone Oracle TYPE (which cannot be an associative array) with requiring the definition of a package that can be seen by all in order that the TYPE it defines there can be used by all.

You can change which python you're using with your IDE, if you've already downloaded python 3.x it shouldn't be too hard to switch. But your script works fine on python 3.x, I would just change

print ("your name is" + input_variable)

to

print ("your name is", input_variable)

Because with the comma it prints with a whitespace in between your name is and whatever the user inputted. AND: if you're using 2.7 just use raw_input instead of input.

Here is the codepen demo showing the solution:

• Demo - Fill remaining vertical space with CSS using display:flex

Important highlights:

• all containers from html, body, ... .container, should have the height set to 100%
• introducing flex to ANY of the flex items will trigger calculation of the items sizes based on flex distribution:
  • if only one cell is set to flex, for example: flex: 1 then this flex item will occupy the remaining of the space
  • if there are more than one with the flex property, the calculation will be more complicated. For example, if the item 1 is set to flex: 1 and the item 2 is se to flex: 2 then the item 2 will take twice more of the remaining space
    • NOT TRUE: the item 2 will be twice larger than the item 1
    • check more about the concept of the remaining space: https://developer.mozilla.org/en-US/docs/Web/CSS/flex-grow
• Main Size Property
  • depends on the value of the flex-direction property
  • in our case height is just a preferred size
  • it will be overwritten in the presence of flex property: https://www.w3.org/TR/css-flexbox-1/#propdef-flex
    • When a box is a flex item, flex is consulted instead of the main size property to determine the main size of the box
  • min-* and max-* will be respected

Check if your PHP installation works.

Check which php.ini file you are running in Apache's configuration and use it to run php.exe...

As of March 2016, in Chrome 49.0, for...of works for HTMLCollection:

this.headers = this.getElementsByTagName("header");

    console.log(header); 
}

See here the documentation.

But it only works if you apply the following workaround before using the for...of:

HTMLCollection.prototype[Symbol.iterator] = Array.prototype[Symbol.iterator];

The same is necessary for using for...of with NodeList:

NamedNodeMap.prototype[Symbol.iterator] = Array.prototype[Symbol.iterator];

I believe/hope for...of will soon work without the above workaround. The open issue is here:

https://bugs.chromium.org/p/chromium/issues/detail?id=401699

Update: See Expenzor's comment below: This has been fixed as of April 2016. You don't need to add HTMLCollection.prototype[Symbol.iterator] = Array.prototype[Symbol.iterator]; to iterate over an HTMLCollection with for...of

I know the answers are relating to changing grouped table cells, but in case someone is wanting to also change the tableview's background color:

Not only do you need to set:

tableview.backgroundColor = color;

You also need to change or get rid of the background view:

tableview.backgroundView = nil;  

#include <stdio.h>
main()
{
int c,sp,tb,nl;
sp = 0;
tb = 0;
nl = 0;
while((c = getchar()) != EOF)
{
   switch( c )
{
   case ' ':
        ++sp;
     printf("space:%d\n", sp);
     break;
   case  '\t':
        ++tb;
     printf("tab:%d\n", tb);
     break;
   case '\n':
        ++nl;
     printf("new line:%d\n", nl);
     break;
  }
 }
}

This will not work correctly, e.g. abcÑxyz will pass thru this as it has a,b,c... you need to work with Collate or check each byte.

I had the same error message, and the problem was also the metadata part of the connection string, but I had to dig a little deeper to solve it and wanted to share this little nugget:

The metadata string is made up of three sections that each look like this:

res://
      (assembly)/
      (model name).(ext)

Where ext is "csdl", "ssdl", and "msl".

For most people, assembly can probably be "*", which seems to indicate that all loaded assemblies will be searched (I haven't done a huge amount of testing of this). This part wasn't an issue for me, so I can't comment on whether you need the assembly name or file name (i.e., with or without ".dll"), though I have seen both suggested.

The model name part should be the name and namespace of your .edmx file, relative to your assembly. So if you have a My.DataAccess assembly and you create DataModels.edmx in a Models folder, its full name is My.DataAccess.Models.DataModels. In this case, you would have "Models.DataModels.(ext)" in your metadata.

If you ever move or rename your .edmx file, you will need to update your metadata string manually (in my experience), and remembering to change the relative namespace will save a few headaches.

Two things. First, you need to qualify the enum reference in your test - rather than "PLUS", it should be "Operator.PLUS". Second, this code would be a lot more readable if you used the enum member names rather than their integral values in the switch statement. I've updated your code:

public enum Operator
{
    PLUS, MINUS, MULTIPLY, DIVIDE
}

public static double Calculate(int left, int right, Operator op)
{
    switch (op)
    {
        default:
        case Operator.PLUS:
            return left + right;

        case Operator.MINUS:
            return left - right;

        case Operator.MULTIPLY:
            return left * right;

        case Operator.DIVIDE:
            return left / right;
    }
}

Call this with:

Console.WriteLine("The sum of 5 and 5 is " + Calculate(5, 5, Operator.PLUS));

This is what I usually do, with collections like sets:

Set<T> adds = new HashSet<T>, dels = new HashSet<T>;
for ( T e: target )
  if ( <has to be removed> ) dels.add ( e );
  else if ( <has to be added> ) adds.add ( <new element> )

target.removeAll ( dels );
target.addAll ( adds );

This creates some extra-memory (the pointers for intermediate sets, but no duplicated elements happen) and extra-steps (iterating again over changes), however usually that's not a big deal and it might be better than working with an initial collection copy.

Session

Session is used for maintaining a dialogue between server and user. It is more secure because it is stored on the server, we cannot easily access it. It embeds cookies on the user computer. It stores unlimited data.

Cookies

Cookies are stored on the local computer. Basically, it maintains user identification, meaning it tracks visitors record. It is less secure than session. It stores limited amount of data, and is maintained for a limited time.

Store all the to be deleted ID's into a table. Then there are 3 ways. 1) loop through all the ID's in the table, then delete one row at a time for X commit interval. X can be a 100 or 1000. It works on OLTP environment and you can control the locks.

2) Use Oracle Bulk Delete

3) Use correlated delete query.

Single query is usually faster than multiple queries because of less context switching, and possibly less parsing.

Deleting the .git folder may cause problems in your git repository. If you want to delete all your commit history but keep the code in its current state, it is very safe to do it as in the following:

1. Checkout

   git checkout --orphan latest_branch

2. Add all the files

   git add -A

3. Commit the changes

   git commit -am "commit message"

4. Delete the branch

   git branch -D main

5. Rename the current branch to main

   git branch -m main

6. Finally, force update your repository

   git push -f origin main

PS: this will not keep your old commit history around

Even if you remove the shared folder via net use * /del, on the server side there is still a connection up there.

In order to get around this problem which Microsoft created by design you should map the drive in a way to let windows think it's another share on another server. The simplest way to do that is to use DNS aliases or ip addresses. In your case, if your first mapping uses the ip address like \\IP\Share with your current credential, you should use something like \\ServerName\Share password /user:Domain\Username this should create a new share with the new credentials.

Microsoft call this behavior by design .. i call it just stupid design.

You say:

The file doesn't seem to be corrupted or of a different format.

However as the error message says, the first 8 bytes of the file are '<table r' ... that is definitely not Excel .xls format. Open it with a text editor (e.g. Notepad) that won't take any notice of the (incorrect) .xls extension and see for yourself.

We already have tons of options to get mean by group, adding one more from mosaic package.

mosaic::mean(speed~dive, data = df)
#dive1 dive2 
#0.579 0.440 

This returns a named numeric vector, if needed a dataframe we can wrap it in stack

stack(mosaic::mean(speed~dive, data = df))

#  values   ind
#1  0.579 dive1
#2  0.440 dive2

data

set.seed(123)
df <- data.frame(dive=factor(sample(c("dive1","dive2"),10,replace=TRUE)),
                 speed=runif(10))

Others have covered the general case. But if you have a byte array of a known form, for example a MAC address, then you can:

byte[] mac = { (byte)0x00, (byte)0x00, (byte)0x00, (byte)0x00, (byte)0x00 };

String str = String.format("%02X:%02X:%02X:%02X:%02X:%02X",
                           mac[0], mac[1], mac[2], mac[3], mac[4], mac[5]); 

There's still one thing that is not highlighted enough, in my opinion, and that is unwanted inheritance.

Here's an incremental example:

I declare in my parent pom:

<dependencies>
        <dependency>
            <groupId>com.google.guava</groupId>
            <artifactId>guava</artifactId>
            <version>19.0</version>
        </dependency>
</dependencies>

boom! I have it in my Child A, Child B and Child C modules:

• Implicilty inherited by child poms
• A single place to manage
• No need to redeclare anything in child poms
• I can still redelcare and override to version 18.0 in a Child B if I want to.

But what if I end up not needing guava in Child C, and neither in the future Child D and Child E modules?

They will still inherit it and this is undesired! This is just like Java God Object code smell, where you inherit some useful bits from a class, and a tonn of unwanted stuff as well.

This is where <dependencyManagement> comes into play. When you add this to your parent pom, all of your child modules STOP seeing it. And thus you are forced to go into each individual module that DOES need it and declare it again (Child A and Child B, without the version though).

And, obviously, you don't do it for Child C, and thus your module remains lean.

With regard to the specific question of generating a reverse IntStream:

starting from Java 9 you can use the three-argument version of the IntStream.iterate(...):

IntStream.iterate(10, x -> x >= 0, x -> x - 1).forEach(System.out::println);

// Out: 10 9 8 7 6 5 4 3 2 1 0

where:

IntStream.iterate?(int seed, IntPredicate hasNext, IntUnaryOperator next);

• seed - the initial element;
• hasNext - a predicate to apply to elements to determine when the stream must terminate;
• next - a function to be applied to the previous element to produce a new element.

Roman is right, but note that the auto_increment column must be part of the PRIMARY KEY or a UNIQUE KEY (and in almost 100% of the cases, it should be the only column that makes up the PRIMARY KEY):

ALTER TABLE document MODIFY document_id INT AUTO_INCREMENT PRIMARY KEY

I use following line of code to fix this problem. Write the following code in web.config file

<configuration>
    <system.web.extensions>
       <scripting>
       <webServices>
       <jsonSerialization maxJsonLength="50000000"/>
      </webServices>
     </scripting>
   </system.web.extensions>
</configuration>

An alternative approach might be to use another table to contain id values. This other table can then be inner joined on your TABLE to constrain returned rows. This will have the major advantage that you won't need dynamic SQL (problematic at the best of times), and you won't have an infinitely long IN clause.

You would truncate this other table, insert your large number of rows, then perhaps create an index to aid the join performance. It would also let you detach the accumulation of these rows from the retrieval of data, perhaps giving you more options to tune performance.

Update: Although you could use a temporary table, I did not mean to imply that you must or even should. A permanent table used for temporary data is a common solution with merits beyond that described here.

Simple solution which worked for me.

1. Install Vim editor for windows.
2. Open VS 2012 project solution using Vim editor and modify the version targetting Visual studio solution 10.
3. Open solution with Visual studio 2010.. and continue with your work ;)

I know that I am late to the party, but I just made a library for this that I think could really help. It is extremely simple, that's why I think you should use it. It is called TableIT.

Basic Use

To use it, first follow the download instructions on the GitHub Page.

Then import it:

import TableIt

Then make a list of lists where each inner list is a row:

table = [
    [4, 3, "Hi"],
    [2, 1, 808890312093],
    [5, "Hi", "Bye"]
]

Then all you have to do is print it:

TableIt.printTable(table)

This is the output you get:

+--------------------------------------------+
| 4            | 3            | Hi           |
| 2            | 1            | 808890312093 |
| 5            | Hi           | Bye          |
+--------------------------------------------+

Field Names

You can use field names if you want to (if you aren't using field names you don't have to say useFieldNames=False because it is set to that by default):

TableIt.printTable(table, useFieldNames=True)

From that you will get:

+--------------------------------------------+
| 4            | 3            | Hi           |
+--------------+--------------+--------------+
| 2            | 1            | 808890312093 |
| 5            | Hi           | Bye          |
+--------------------------------------------+

There are other uses to, for example you could do this:

import TableIt

myList = [
    ["Name", "Email"],
    ["Richard", "[email protected]"],
    ["Tasha", "[email protected]"]
]

TableIt.print(myList, useFieldNames=True)

From that:

+-----------------------------------------------+
| Name                  | Email                 |
+-----------------------+-----------------------+
| Richard               | [email protected] |
| Tasha                 | [email protected]    |
+-----------------------------------------------+

Or you could do:

import TableIt

myList = [
    ["", "a", "b"],
    ["x", "a + x", "a + b"],
    ["z", "a + z", "z + b"]
]

TableIt.printTable(myList, useFieldNames=True)

And from that you get:

+-----------------------+
|       | a     | b     |
+-------+-------+-------+
| x     | a + x | a + b |
| z     | a + z | z + b |
+-----------------------+

Colors

You can also use colors.

You use colors by using the color option (by default it is set to None) and specifying RGB values.

Using the example from above:

import TableIt

myList = [
    ["", "a", "b"],
    ["x", "a + x", "a + b"],
    ["z", "a + z", "z + b"]
]

TableIt.printTable(myList, useFieldNames=True, color=(26, 156, 171))

Then you will get:

Please note that printing colors might not work for you but it does works the exact same as the other libraries that print colored text. I have tested and every single color works. The blue is not messed up either as it would if using the default 34m ANSI escape sequence (if you don't know what that is it doesn't matter). Anyway, it all comes from the fact that every color is RGB value rather than a system default.

More Info

If the project came with a Visual Studio project file, then that should already be configured to find the headers for you. If not, you'll have to add the include file directory to the project settings by right-clicking the project and selecting Properties, clicking on "C/C++", and adding the directory containing the include files to the "Additional Include Directories" edit box.

Here are the commands to restore the old behavior:

# create a script that calls launchctl iterating through /etc/launchd.conf
echo '#!/bin/sh

while read line || [[ -n $line ]] ; do launchctl $line ; done < /etc/launchd.conf;
' > /usr/local/bin/launchd.conf.sh

# make it executable
chmod +x /usr/local/bin/launchd.conf.sh

# launch the script at startup
echo '<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key>
  <string>launchd.conf</string>
  <key>ProgramArguments</key>
  <array>
    <string>sh</string>
    <string>-c</string>
    <string>/usr/local/bin/launchd.conf.sh</string>
  </array>
  <key>RunAtLoad</key>
  <true/>
</dict>
</plist>
' > /Library/LaunchAgents/launchd.conf.plist

Now you can specify commands like setenv JAVA_HOME /Library/Java/Home in /etc/launchd.conf.

on button click, first open the database, fetch the data and close the data base like this

public class cytaty extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.galeria);

        Button bLosuj = (Button) findViewById(R.id.button1);
        bLosuj.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            myDatabaseHelper = new DatabaseHelper(cytaty.this);
            myDatabaseHelper.openDataBase();

            String text = myDatabaseHelper.getYourData(); //this is the method to query

            myDatabaseHelper.close(); 
            // set text to your TextView
            }
        });
    }
}

and your getYourData() in database class would be like this

public String[] getAppCategoryDetail() {

    final String TABLE_NAME = "name of table";

    String selectQuery = "SELECT  * FROM " + TABLE_NAME;
    SQLiteDatabase db  = this.getReadableDatabase();
    Cursor cursor      = db.rawQuery(selectQuery, null);
    String[] data      = null;

    if (cursor.moveToFirst()) {
        do {
           // get the data into array, or class variable
        } while (cursor.moveToNext());
    }
    cursor.close();
    return data;
}

With the latest version of Adobe Reader, Adobe Reader XI, it seems that you can save the form.

From their webpage: Type your responses right on the PDF form, or click through and fill in the form fields. Then save and submit

You can delete all the rows with this command.But remember one thing that once you run truncate command you cannot rollback it.

  truncate tableName;

Since Array.slice() does not do deep copying, it is not suitable for multidimensional arrays:

var a =[[1], [2], [3]];
var b = a.slice();

b.shift().shift();
// a is now [[], [2], [3]]

Note that although I've used shift().shift() above, the point is just that b[0][0] contains a pointer to a[0][0] rather than a value.

Likewise delete(b[0][0]) also causes a[0][0] to be deleted and b[0][0]=99 also changes the value of a[0][0] to 99.

jQuery's extend method does perform a deep copy when a true value is passed as the initial argument:

var a =[[1], [2], [3]];
var b = $.extend(true, [], a);

b.shift().shift();
// a is still [[1], [2], [3]]

You cannot iterate over them directly, but you can find all the keys and then just sort them.

var a = new Array();
a['b'] = 1;
a['z'] = 1;
a['a'] = 1;    

function keys(obj)
{
    var keys = [];

    for(var key in obj)
    {
        if(obj.hasOwnProperty(key))
        {
            keys.push(key);
        }
    }

    return keys;
}

keys(a).sort(); // ["a", "b", "z"]

However there is no need to make the variable 'a' an array. You are really just using it as an object and should create it like this:

var a = {};
a["key"] = "value";

I would go for aspect-ratio, it offers way more possibilities.

/* Exact aspect ratio */
@media (aspect-ratio: 2/1) {
    ...
}

/* Minimum aspect ratio */
@media (min-aspect-ratio: 16/9) {
    ...
}

/* Maximum aspect ratio */
@media (max-aspect-ratio: 8/5) {
    ...
}

Both, orientation and aspect-ratio depend on the actual size of the viewport and have nothing todo with the device orientation itself.

OSError: [Errno 8] Exec format error can happen if there is no shebang line at the top of the shell script and you are trying to execute the script directly. Here's an example that reproduces the issue:

>>> with open('a','w') as f: f.write('exit 0') # create the script
... 
>>> import os
>>> os.chmod('a', 0b111101101) # rwxr-xr-x make it executable                       
>>> os.execl('./a', './a')     # execute it                                            
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/os.py", line 312, in execl
    execv(file, args)
OSError: [Errno 8] Exec format error

To fix it, just add the shebang e.g., if it is a shell script; prepend #!/bin/sh at the top of your script:

>>> with open('a','w') as f: f.write('#!/bin/sh\nexit 0')
... 
>>> os.execl('./a', './a')

It executes exit 0 without any errors.

On POSIX systems, shell parses the command line i.e., your script won't see spaces around = e.g., if script is:

#!/usr/bin/env python
import sys
print(sys.argv)

then running it in the shell:

$ /usr/local/bin/script hostname = '<hostname>' -p LONGLIST

produces:

['/usr/local/bin/script', 'hostname', '=', '<hostname>', '-p', 'LONGLIST']

Note: no spaces around '='. I've added quotes around <hostname> to escape the redirection metacharacters <>.

To emulate the shell command in Python, run:

from subprocess import check_call

cmd = ['/usr/local/bin/script', 'hostname', '=', '<hostname>', '-p', 'LONGLIST']
check_call(cmd)

Note: no shell=True. And you don't need to escape <> because no shell is run.

"Exec format error" might indicate that your script has invalid format, run:

$ file /usr/local/bin/script

to find out what it is. Compare the architecture with the output of:

$ uname -m

Use this:

\d{10}

I hope it helps.

ReportClass report = (ReportClass)Activator.CreateInstance(Type.GetType(reportClass));

why do u want to write a code like this? If you have a class 'ReportClass' is available, you can instantiate it directly as shown below.

ReportClass report = new ReportClass();

The code ReportClass report = (ReportClass)Activator.CreateInstance(Type.GetType(reportClass)); is used when you dont have the necessary class available, but you want to instantiate and or or invoke a method dynamically.

I mean it is useful when u know the assembly but while writing the code you dont have the class ReportClass available.

Standard C99:

#include <time.h>

time_t t0 = time(0);
// ...
time_t t1 = time(0);
double datetime_diff_ms = difftime(t1, t0) * 1000.;

clock_t c0 = clock();
// ...
clock_t c1 = clock();
double runtime_diff_ms = (c1 - c0) * 1000. / CLOCKS_PER_SEC;

The precision of the types is implementation-defined, ie the datetime difference might only return full seconds.

In config/database.php I changed the default DB connection from mysql to sqlite. I deleted the .env file (actually renamed it) and created the sqlite file with touch storage/database.sqlite. The migration worked with sqlite.

Then I switched back the config/database.php default DB connection to mysql and recovered the .env file. The migration worked with mysql.

It doesn't make sense I guess. Maybe was something serverside.

In my case issue was that numberOfRowsInSection was returning similar number of rows after calling tableView.deleteRows(...).

Since this was the required behaviour in my case, I ended up calling tableView.reloadData() instead of tableView.deleteRows(...) in cases where numberOfRowsInSection will remain same after deleting a row.

I met some problems in Clion and finally, I solved them. Here is some experience.

1. Download and install MinGW
2. g++ and gcc package should be installed by default. Use the MinGW installation manager to install mingw32-libz and mingw32-make. You can open MinGW installation manager through C:\MinGW\libexec\mingw-get.exe This step is the most important step. If Clion cannot find make, C compiler and C++ compiler, recheck the MinGW installation manager to make every necessary package is installed.
3. In Clion, open File->Settings->Build,Execution,Deployment->Toolchains. Set MinGW home as your local MinGW file.
4. Start your "Hello World"!

The \n largely works for us, but Outlook does sometimes take it upon itself to remove the line breaks as you say.

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

You can remove non numeric characters using regex

onTextChanged (text) {
    this.setState({
        myNumber: text.replace(/\D/g, ''),
    });
}

Try this:

$tempDate = explode('-','03-23-15');
$date = '20'.$tempDate[2].'-'.$tempDate[0].'-'.$tempDate[1];

You can do something like this

var now = moment();
var time = now.hour() + ':' + now.minutes() + ':' + now.seconds();
time = time + ((now.hour()) >= 12 ? ' PM' : ' AM');

com.google.common.collect.Sets.newHashSet(MyEnum.values()).contains("myValue")

The clear way to achieve this,

For example:

If you have dataFile.txt on your current directory

import java.io.*;
import java.util.Scanner;
import java.io.FileNotFoundException;

public class readByLine
{
    public readByLine() throws FileNotFoundException
    {
        Scanner linReader = new Scanner(new File("dataFile.txt"));

        while (linReader.hasNext())
        {
            String line = linReader.nextLine();
            System.out.println(line);
        }
        linReader.close();

    }

    public static void main(String args[])  throws FileNotFoundException
    {
        new readByLine();
    }
}

The output like as below,

:set list will show all whitespaces as a character. Everything but a space will look different than its normal state, which means that if you still see a plain old space, it's really a plain old space. :)

Do simultaneous work on the dev branch. What happens is that in your scenario the feature branch moves forward from the tip of the dev branch, but the dev branch does not change. It's easier to draw as a straight line, because it can be thought of as forward motion. You made it to point A on dev, and from there you simply continued on a parallel path. The two branches have not really diverged.

Now, if you make a commit on dev, before merging, you will again begin at the same commit, A, but now features will go to C and dev to B. This will show the split you are trying to visualize, as the branches have now diverged.

*-----*Dev-------*Feature

Versus

       /----*DevB
*-----*DevA
       \----*FeatureC

simple and easier solution:

select extract(hour from systimestamp) from dual;

EXTRACT(HOURFROMSYSTIMESTAMP)
-----------------------------
                           16 

If you really have:

var s = ['{"Select":"11", "PhotoCount":"12"}','{"Select":"21", "PhotoCount":"22"}'];

then simply:

var objs = $.map(s, $.parseJSON);

Here's a demo.

With ES6 you can simply do:

 for(const element of Results) {
      element.Active = "false";
 }

Configuring a button (or any widget) in Tkinter is done by calling a configure method "config"

To change the size of a button called button1 you simple call

button1.config( height = WHATEVER, width = WHATEVER2 )

If you know what size you want at initialization these options can be added to the constructor.

button1 = Button(self, text = "Send", command = self.response1, height = 100, width = 100) 

You can simulate capturing in vanilla awk too, without extensions. Its not intuitive though:

step 1. use gensub to surround matches with some character that doesnt appear in your string. step 2. Use split against the character. step 3. Every other element in the splitted array is your capture group.

$ echo 'ab cb ad' | awk '{ split(gensub(/a./,SUBSEP"&"SUBSEP,"g",$0),cap,SUBSEP); print cap[2]"|" cap[4] ; }'
ab|ad

I searched for multiple options to get my git reset to specific commit, but most of them aren't so satisfactory.

I generally use this to reset the git to the specific commit in source tree.

1. select commit to reset on sourcetree.

2. In dropdowns select the active branch , first Parent Only

3. And right click on "Reset branch to this commit" and select hard reset option (soft, mixed and hard)

4. and then go to terminal git push -f

You should be all set!

The easiest way to import the exact numbers is to add a decimal after the numbers in your l1 and l2. Python interprets this decimal point as instructions from you to include the exact number. If you need to restrict it to some decimal place, you should be able to create a print command that limits the output, something simple like:

print variable_example[:13]

Would restrict it to the tenth decimal place, assuming your data has two integers left of the decimal.

In order to check if an object is compatible with a given type variable, instead of writing

u is t

you should write

typeof(t).IsInstanceOfType(u)

I know this is old but since no one mentioned about using awk:

    firstString="I love Suzi and Marry"
    echo $firstString | awk '{gsub("Suzi","Sara"); print}'

There is still quirks and inconsistencies in 2019.

For example with scaled svg and pointer events, between browsers.

None of the answer of this topic are working anymore. (maybe those with jquery)

Here is an alternative, by testing with javascript if a css rule is supported, via the native CSS support api. Might evolve, to be adapted!

Note that it's possible to pass many css rules separated by a semicolon, for the finest detection.

if (CSS.supports("( -webkit-box-reflect:unset )")){
  console.log("WEBKIT BROWSER")
  // More math...
 } else {
  console.log("ENJOY")
 }

if (CSS.supports("( -moz-user-select:unset )")){
  console.log("FIREFOX!!!")
 }

Beware to not use it in loops, for performance it's better to populate a constant on load:

const ff = CSS.supports("( -moz-user-select:unset )")
if (ff){ //... } 

Using CSS only, the above would be:

@supports (-webkit-box-reflect:unset) {
  div {
    background: red
  }
}

@supports (-moz-user-select:unset) {
  div {
    background: green
  }
}

<div>
  Hello world!!
</div>

List of possible -webkit- only css rules.

List of possible -moz- only rules.

Can I use css support?

In "References", import DAO 3.6 object reference.

private sub showTableData

dim db as dao.database
dim rs as dao.recordset

set db = currentDb
set rs = db.OpenRecordSet("myTable") 'myTable is a MS-Access table created previously

'populate the table
rs.movelast
rs.movefirst

do while not rs.EOF
   debug.print(rs!myField) 'myField is a field name in table myTable
   rs.movenext             'press Ctrl+G to see debuG window beneath
loop

msgbox("End of Table")

end sub

You can interate data objects like queries and filtered tables in different ways:

Trhough query:

private sub showQueryData

dim db as dao.database
dim rs as dao.recordset
dim sqlStr as string

sqlStr = "SELECT * FROM customers as c WHERE c.country='Brazil'"

set db = currentDb
set rs = db.openRecordset(sqlStr)

rs.movefirst

do while not rs.EOF
  debug.print("cust ID: " & rs!id & " cust name: " & rs!name)
  rs.movenext
loop

msgbox("End of customers from Brazil")

end sub

You should also look for "Filter" property of the recordset object to filter only the desired records and then interact with them in the same way (see VB6 Help in MS-Access code window), or create a "QueryDef" object to run a query and use it as a recordset too (a little bit more tricky). Tell me if you want another aproach.

I hope I've helped.

The suggestion that using range(len()) is the equivalent of using enumerate() is incorrect. They return the same results, but they are not the same.

Using enumerate() actually gives you key/value pairs. Using range(len()) does not.

Let's check range(len()) first (working from the example from the original poster):

words = ['aba', 'xyz', 'xgx', 'dssd', 'sdjh']
    print range(len(words))

This gives us a simple list:

[0, 1, 2, 3, 4]

... and the elements in this list serve as the "indexes" in our results.

So let's do the same thing with our enumerate() version:

words = ['aba', 'xyz', 'xgx', 'dssd', 'sdjh']    
   print enumerate(words)

This certainly doesn't give us a list:

<enumerate object at 0x7f6be7f32c30>

...so let's turn it into a list, and see what happens:

print list(enumerate(words))

It gives us:

[(0, 'aba'), (1, 'xyz'), (2, 'xgx'), (3, 'dssd'), (4, 'sdjh')]

These are actual key/value pairs.

So this ...

words = ['aba', 'xyz', 'xgx', 'dssd', 'sdjh']

for i in range(len(words)):
    print "words[{}] = ".format(i), words[i]

... actually takes the first list (Words), and creates a second, simple list of the range indicated by the length of the first list.

So we have two simple lists, and we are merely printing one element from each list in order to get our so-called "key/value" pairs.

But they aren't really key/value pairs; they are merely two single elements printed at the same time, from different lists.

Whereas the enumerate () code:

for i, word in enumerate(words):
    print "words[{}] = {}".format(i, word)

... also creates a second list. But that list actually is a list of key/value pairs, and we are asking for each key and value from a single source -- rather than from two lists (like we did above).

So we print the same results, but the sources are completely different -- and handled completely differently.

Somewhat simpler XPath 1.0 solution, adapted from Tomalek's (posted here) and Dimitre's (here):

concat(substring($s1, 1 div number($cond)), substring($s2, 1 div number(not($cond))))

Note: I found an explicit number() was required to convert the bool to an int otherwise some XPath evaluators threw a type mismatch error. Depending on how strict your XPath processor is type-matching you may not need it.

Google play finds you as developer via your keystore.

and maybe your country IP is banned on Google when you generate your new keystore.

change your IP Address and generate new keystore, the problem will be fixed.

if you didn't succeed, use another Gmail in Android Studio and generate new keystore.

Why not just:

int plusIndex = s.indexOf("+");
if (plusIndex != -1) {
    String before = s.substring(0, plusIndex);
    // Use before
}

It's not really clear why your original version didn't work, but then you didn't say what actually happened. If you want to split not using regular expressions, I'd personally use Guava:

Iterable<String> bits = Splitter.on('+').split(s);
String firstPart = Iterables.getFirst(bits, "");

If you're going to use split (either the built-in version or Guava) you don't need to check whether it contains + first - if it doesn't there'll only be one result anyway. Obviously there's a question of efficiency, but it's simpler code:

// Calling split unconditionally
String[] parts = s.split("\\+");
s = parts[0];

Note that writing String[] parts is preferred over String parts[] - it's much more idiomatic Java code.

- Here its more about the coding style than being the functionality....

- The 1st option is very clear, but then the 2nd one is quite elegant... no offense, its just my view..

A solution to ensure that images don't get cut when printed in a Web page is to have the following CSS rule:

@media print { 
  img { 
    max-width:100% !important;
  } 
}

As other answers have pointed, on UNIX systems the numbers represent CPU load averages over 1/5/15 minute periods. But on Linux (and consequently Android), what it represents is something different.

After a kernel patch dating back to 1993 (a great in-depth article on the subject), in Linux the load average numbers no longer strictly represent the CPU load: as the calculation accounts not only for CPU bound processes, but also for processes in uninterruptible wait state - the original goal was to account for I/O bound processes this way, to represent more of a "system load" than just CPU load. The issue is that since 1993 the usage of uninterruptible state has grown in Linux kernel, and it no longer typically represents an I/O bound process. The problem is further exacerbated by some Linux devs using uninterruptible waits as an easy wait to avoid accommodating signals in their implementations. As a result, in Linux (and Android) we can see skewed high load average numbers that do not objectively represent the real load. There are Android user reports about unreasonable high load averages contrasting low CPU utilization. For example, my old Android phone (with 2 CPU cores) normally shown average load of ~12 even when the system and CPUs were idle. Hence, average load numbers in Linux (Android) does not turn out to be a reliable performance metric.

My favorite way to do this is with an extension function called 'Map':

public static void Map<T>(this IEnumerable<T> source, Action<T> func)
{
    foreach (T i in source)
        func(i);
}

Then you can add all the rows like so:

X.Map(item => this.dataGridView1.Rows.Add(item.ID, item.Name));

update: Copied material that was on the R wiki at http://rwiki.sciviews.org/doku.php?id=tips:graphics-base:2yaxes, link now broken: also available from the wayback machine

Two different y axes on the same plot

(some material originally by Daniel Rajdl 2006/03/31 15:26)

Please note that there are very few situations where it is appropriate to use two different scales on the same plot. It is very easy to mislead the viewer of the graphic. Check the following two examples and comments on this issue (example1, example2 from Junk Charts), as well as this article by Stephen Few (which concludes “I certainly cannot conclude, once and for all, that graphs with dual-scaled axes are never useful; only that I cannot think of a situation that warrants them in light of other, better solutions.”) Also see point #4 in this cartoon ...

If you are determined, the basic recipe is to create your first plot, set par(new=TRUE) to prevent R from clearing the graphics device, creating the second plot with axes=FALSE (and setting xlab and ylab to be blank – ann=FALSE should also work) and then using axis(side=4) to add a new axis on the right-hand side, and mtext(...,side=4) to add an axis label on the right-hand side. Here is an example using a little bit of made-up data:

set.seed(101)
x <- 1:10
y <- rnorm(10)
## second data set on a very different scale
z <- runif(10, min=1000, max=10000) 
par(mar = c(5, 4, 4, 4) + 0.3)  # Leave space for z axis
plot(x, y) # first plot
par(new = TRUE)
plot(x, z, type = "l", axes = FALSE, bty = "n", xlab = "", ylab = "")
axis(side=4, at = pretty(range(z)))
mtext("z", side=4, line=3)

twoord.plot() in the plotrix package automates this process, as does doubleYScale() in the latticeExtra package.

Another example (adapted from an R mailing list post by Robert W. Baer):

## set up some fake test data
time <- seq(0,72,12)
betagal.abs <- c(0.05,0.18,0.25,0.31,0.32,0.34,0.35)
cell.density <- c(0,1000,2000,3000,4000,5000,6000)

## add extra space to right margin of plot within frame
par(mar=c(5, 4, 4, 6) + 0.1)

## Plot first set of data and draw its axis
plot(time, betagal.abs, pch=16, axes=FALSE, ylim=c(0,1), xlab="", ylab="", 
   type="b",col="black", main="Mike's test data")
axis(2, ylim=c(0,1),col="black",las=1)  ## las=1 makes horizontal labels
mtext("Beta Gal Absorbance",side=2,line=2.5)
box()

## Allow a second plot on the same graph
par(new=TRUE)

## Plot the second plot and put axis scale on right
plot(time, cell.density, pch=15,  xlab="", ylab="", ylim=c(0,7000), 
    axes=FALSE, type="b", col="red")
## a little farther out (line=4) to make room for labels
mtext("Cell Density",side=4,col="red",line=4) 
axis(4, ylim=c(0,7000), col="red",col.axis="red",las=1)

## Draw the time axis
axis(1,pretty(range(time),10))
mtext("Time (Hours)",side=1,col="black",line=2.5)  

## Add Legend
legend("topleft",legend=c("Beta Gal","Cell Density"),
  text.col=c("black","red"),pch=c(16,15),col=c("black","red"))

Similar recipes can be used to superimpose plots of different types – bar plots, histograms, etc..

This is a part from a REST-Service I´ve written recently.

var select = $("#productSelect")
for (var prop in data) {
    var option = document.createElement('option');
    option.innerHTML = data[prop].ProduktName
    option.value = data[prop].ProduktName;
    select.append(option)
}

The reason why im posting this is because appendChild() wasn´t working in my case so I decided to put up another possibility that works aswell.

Both Tom and Burton's answers work for me eventually, but I had a little trouble figuring out how to apply them to a ModelChoiceField.

The only trick to it is that the choices are stored as tuples of (<model's ID>, <model's unicode repr>), so if you want to set the initial model selection, you pass the model's ID as the initial value, not the object itself or it's name or anything else. Then it's as simple as:

form = EmployeeForm(initial={'manager': manager_employee_id})

Alternatively the initial argument can be ignored in place of an extra line with:

form.fields['manager'].initial = manager_employee_id

Had the same issue; validated HTML & found I was missing a name="email" attribute from an <input />. Always validate the HTML to be positive your HTML is valid. After I added it, validate() worked perfectly.

You can avoid blocking execution by writing the plot to an array, then displaying the array in a different thread. Here is an example of generating and displaying plots simultaneously using pf.screen from pyformulas 0.2.8:

import pyformulas as pf
import matplotlib.pyplot as plt
import numpy as np
import time

fig = plt.figure()

canvas = np.zeros((480,640))
screen = pf.screen(canvas, 'Sinusoid')

start = time.time()
while True:
    now = time.time() - start

    x = np.linspace(now-2, now, 100)
    y = np.sin(2*np.pi*x) + np.sin(3*np.pi*x)
    plt.xlim(now-2,now+1)
    plt.ylim(-3,3)
    plt.plot(x, y, c='black')

    # If we haven't already shown or saved the plot, then we need to draw the figure first...
    fig.canvas.draw()

    image = np.fromstring(fig.canvas.tostring_rgb(), dtype=np.uint8, sep='')
    image = image.reshape(fig.canvas.get_width_height()[::-1] + (3,))

    screen.update(image)

#screen.close()

Result:

Have a look at the syntax for adding a remote repo.

git remote add origin <url_of_remote repository>

Example:

git remote add origin [email protected]:peter/first_app.git

Let us dissect the command :

git remote this is used to manage your Central servers for hosting your git repositories.

May be you are using Github for your central repository stuff. I will give you a example and explain the git remote add origin command

Suppose I am working with GitHub and BitBucket for the central servers for the git repositories and have created repositories on both the websites for my first-app project.

Now if I want to push my changes to both these git servers then I will need to tell git how to reach these central repositories. So I will have to add these,

For GitHub

git remote add gh_origin https://github.com/user/first-app-git.git

And For BitBucket

git remote add bb_origin https://[email protected]/user/first-app-git.git

I have used two variables ( as far it is easy for me to call them variables ) gh_origin ( gh FOR GITHUB ) and bb_origin ( bb for BITBUCKET ) just to explain you we can call origin anything we want.

Now after making some changes I will have to send(push) all these changes to central repositories so that other users can see these changes. So I call

Pushing to GitHub

git push gh_origin master

Pushing to BitBucket

git push bb_origin master

gh_origin is holding value of https://github.com/user/first-app-git.git and bb_origin is holding value of https://[email protected]/user/first-app-git.git

This two variables are making my life easier

as whenever I need to send my code changes I need to use this words instead of remembering or typing the URL for the same.

Most of the times you wont see anything except than origin as most of the times you will deal with only one central repository like Github or BitBucket for example.

Different people who come to this question mean different things by a popup box. I highly recommend reading the Temporary Views documentation. My answer is largely a summary of this and other related documentation.

Alert (show me an example)

Alerts display a title and an optional message. The user must acknowledge it (a one-button alert) or make a simple choice (a two-button alert) before going on. You create an alert with a UIAlertController.

It is worth quoting the documentation's warning and advice about creating unnecessary alerts.

Notes:

• See also Alert Views, but starting in iOS 8 UIAlertView was deprecated. You should use UIAlertController to create alerts now.
• iOS Fundamentals: UIAlertView and UIAlertController (tutorial)

Action Sheet (show me an example)

Action Sheets give the user a list of choices. They appear either at the bottom of the screen or in a popover depending on the size and orientation of the device. As with alerts, a UIAlertController is used to make an action sheet. Before iOS 8, UIActionSheet was used, but now the documentation says:

Important: UIActionSheet is deprecated in iOS 8. (Note that UIActionSheetDelegate is also deprecated.) To create and manage action sheets in iOS 8 and later, instead use UIAlertController with a preferredStyle of UIAlertControllerStyleActionSheet.

Modal View (show me an example)

A modal view is a self-contained view that has everything it needs to complete a task. It may or may not take up the full screen. To create a modal view, use a UIPresentationController with one of the Modal Presentation Styles.

See also

• Presenting View Controllers from Other View Controllers
• Modal Contexts

Popover (show me an example)

A Popover is a view that appears when a user taps on something and disappears when tapping off it. It has an arrow showing the control or location from where the tap was made. The content can be just about anything you can put in a View Controller. You make a popover with a UIPopoverPresentationController. (Before iOS 8, UIPopoverController was the recommended method.)

In the past popovers were only available on the iPad, but starting with iOS 8 you can also get them on an iPhone (see here, here, and here).

See also

• View Controllers: Popovers

Notifications

Notifications are sounds/vibrations, alerts/banners, or badges that notify the user of something even when the app is not running in the foreground.

See also

• Local and Remote Notification Programming Guide
• Simple, interactive notifications in iOS 8

A note about Android Toasts

In Android, a Toast is a short message that displays on the screen for a short amount of time and then disappears automatically without disrupting user interaction with the app.

People coming from an Android background want to know what the iOS version of a Toast is. Some examples of these questions can he found here, here, here, and here. The answer is that there is no equivalent to a Toast in iOS. Various workarounds that have been presented include:

• Make your own with a subclassed UIView
• Import a third party project that mimics a Toast
• Use a buttonless Alert with a timer

However, my advice is to stick with the standard UI options that already come with iOS. Don't try to make your app look and behave exactly the same as the Android version. Think about how to repackage it so that it looks and feels like an iOS app.

simply use delete, but be aware that you should read fully what the effects are of using this:

 delete object.index; //true
 object.index; //undefined

but if I was to use like so:

var x = 1; //1
delete x; //false
x; //1

but if you do wish to delete variables in the global namespace, you can use it's global object such as window, or using this in the outermost scope i.e

var a = 'b';
delete a; //false
delete window.a; //true
delete this.a; //true

http://perfectionkills.com/understanding-delete/

another fact is that using delete on an array will not remove the index but only set the value to undefined, meaning in certain control structures such as for loops, you will still iterate over that entity, when it comes to array's you should use splice which is a prototype of the array object.

Example Array:

var myCars=new Array();
myCars[0]="Saab";
myCars[1]="Volvo";
myCars[2]="BMW";

if I was to do:

delete myCars[1];

the resulting array would be:

["Saab", undefined, "BMW"]

but using splice like so:

myCars.splice(1,1);

would result in:

["Saab", "BMW"]

I've tried different numbers, and it always acts as if the 0s aren't there and sorts the numbers correctly otherwise. Anyone know why?

You're getting a lexicographical sort (e.g. convert objects to strings, and sort them in dictionary order), which is the default sort behavior in Javascript:

https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Array/sort

array.sort([compareFunction])

Parameters

compareFunction

Specifies a function that defines the sort order. If omitted, the array is sorted lexicographically (in dictionary order) according to the string conversion of each element.

In the ECMAscript specification (the normative reference for the generic Javascript), ECMA-262, 3rd ed., section 15.4.4.11, the default sort order is lexicographical, although they don't come out and say it, instead giving the steps for a conceptual sort function that calls the given compare function if necessary, otherwise comparing the arguments when converted to strings:

13. If the argument comparefn is undefined, go to step 16.
14. Call comparefn with arguments x and y.
15. Return Result(14).
16. Call ToString(x).
17. Call ToString(y).
18. If Result(16) < Result(17), return -1.
19. If Result(16) > Result(17), return 1.
20. Return +0.

As of Oracle 9i, you can use CONNECT BY.

SELECT LPAD(' ', (LEVEL - 1) * 4) || "Name" AS "Name"
FROM (SELECT * FROM TMP_NODE ORDER BY "Order")
CONNECT BY PRIOR "Id" = "ParentId"
START WITH "Id" IN (SELECT "Id" FROM TMP_NODE WHERE "ParentId" = 0)

As of SQL Server 2005, you can use a recursive common table expression (CTE).

WITH [NodeList] (
  [Id]
  , [ParentId]
  , [Level]
  , [Order]
) AS (
  SELECT [Node].[Id]
    , [Node].[ParentId]
    , 0 AS [Level]
    , CONVERT([varchar](MAX), [Node].[Order]) AS [Order]
  FROM [Node]
  WHERE [Node].[ParentId] = 0
  UNION ALL
  SELECT [Node].[Id]
    , [Node].[ParentId]
    , [NodeList].[Level] + 1 AS [Level]
    , [NodeList].[Order] + '|'
      + CONVERT([varchar](MAX), [Node].[Order]) AS [Order]
  FROM [Node]
    INNER JOIN [NodeList] ON [NodeList].[Id] = [Node].[ParentId]
) SELECT REPLICATE(' ', [NodeList].[Level] * 4) + [Node].[Name] AS [Name]
FROM [Node]
  INNER JOIN [NodeList] ON [NodeList].[Id] = [Node].[Id]
ORDER BY [NodeList].[Order]

Both will output the following results.

Name
'Node 1'
'    Node 1.1'
'        Node 1.1.1'
'    Node 1.2'
'Node 2'
'    Node 2.1'

(Assuming you don't have/want line breaks in your string...)

How long is this string really?

I suspect there is a limit to how long a line read from a file or from the commandline can be, and because the end of the line gets choped off the parser sees something like s1="some very long string.......... (without an ending ") and thus throws a parsing error?

You can split long lines up in multiple lines by escaping linebreaks in your source like this:

s1="some very long string.....\
...\
...."

The NEW values (or NEW_BUFFER as you have renamed them) are only available when INSERTING and UPDATING. For DELETING you would need to use OLD (OLD_BUFFER). So your trigger would become:

CREATE or REPLACE TRIGGER test001
  AFTER INSERT OR DELETE OR UPDATE ON tabletest001
  REFERENCING OLD AS old_buffer NEW AS new_buffer 
  FOR EACH ROW WHEN (new_buffer.field1 = 'HBP00' OR old_buffer.field1 = 'HBP00') 

You may need to add logic inside the trigger to cater for code that updates field1 from 'HBP000' to something else.

you can do git reset --hard ORIG_HEAD

since "pull" or "merge" set ORIG_HEAD to be the current state before doing those actions.

At the first glance, I missed, that my "web" service didn't actually start, so that's why nginx couldn't find any host

web_1    | python3: can't open file '/var/www/app/app/app.py': [Errno 2] No such file or directory
web_1 exited with code 2
nginx_1  | [emerg] 1#1: host not found in upstream "web:4044" in /etc/nginx/conf.d/nginx.conf:2

You can use Time::Piece, which shouldn't need installing as it is a core module and has been distributed with Perl 5 since version 10.

use Time::Piece;

my $date = localtime->strftime('%m/%d/%Y');
print $date;

output

06/13/2012

Update

You may prefer to use the dmy method, which takes a single parameter which is the separator to be used between the fields of the result, and avoids having to specify a full date/time format

my $date = localtime->dmy('/');

This produces an identical result to that of my original solution

You might be better off using the Properties Service as you can use these as a kind of persistent global variable.

click 'file > project properties > project properties' to set a key value, or you can use

PropertiesService.getScriptProperties().setProperty('mykey', 'myvalue');

The data can be retrieved with

var myvalue = PropertiesService.getScriptProperties().getProperty('mykey');

With 4 lines, I import a rss to an array.

$feed = implode(file('http://yourdomains.com/feed.rss'));
$xml = simplexml_load_string($feed);
$json = json_encode($xml);
$array = json_decode($json,TRUE);

For a more complex solution

$feed = new DOMDocument();
 $feed->load('file.rss');
 $json = array();
 $json['title'] = $feed->getElementsByTagName('channel')->item(0)->getElementsByTagName('title')->item(0)->firstChild->nodeValue;
 $json['description'] = $feed->getElementsByTagName('channel')->item(0)->getElementsByTagName('description')->item(0)->firstChild->nodeValue;
 $json['link'] = $feed->getElementsByTagName('channel')->item(0)->getElementsByTagName('link')->item(0)->firstChild->nodeValue;
 $items = $feed->getElementsByTagName('channel')->item(0)->getElementsByTagName('item');

 $json['item'] = array();
 $i = 0;

 foreach($items as $key => $item) {
 $title = $item->getElementsByTagName('title')->item(0)->firstChild->nodeValue;
 $description = $item->getElementsByTagName('description')->item(0)->firstChild->nodeValue;
 $pubDate = $item->getElementsByTagName('pubDate')->item(0)->firstChild->nodeValue;
 $guid = $item->getElementsByTagName('guid')->item(0)->firstChild->nodeValue;

 $json['item'][$key]['title'] = $title;
 $json['item'][$key]['description'] = $description;
 $json['item'][$key]['pubdate'] = $pubDate;
 $json['item'][$key]['guid'] = $guid; 
 }

echo json_encode($json);

you don't, declare an interface that declares the methods you would like to call:

public interface MyInterface
{
  void doStuff();
}

public class MyClass implements MyInterface
{
  public void doStuff()
  {
    System.Console.Writeln("done!");
  }
}

then you use

MyInterface mobj = (myInterface)obj;
mobj.doStuff();

If MyClassis not under your control then you can't make it implement some interface, and the other option is to rely on reflection (see this tutorial).

This function works in both bash and zsh, and ensures I/O to the terminal:

# Prompt for a keypress to continue. Customise prompt with $*
function pause {
  >/dev/tty printf '%s' "${*:-Press any key to continue... }"
  [[ $ZSH_VERSION ]] && read -krs  # Use -u0 to read from STDIN
  [[ $BASH_VERSION ]] && </dev/tty read -rsn1
  printf '\n'
}

Quote: "What does the construct x = x || y mean?"

Assigning a default value.

This means providing a default value of y to x, in case x is still waiting for its value but hasn't received it yet or was deliberately omitted in order to fall back to a default.

Also, be wary of additional top level domains that aren't included in some of the answers above.

For example .info, .biz, .ru, .online will throw some sentence parsers but aren't included above.

Here's some info on frequency of top level domains: https://www.westhost.com/blog/the-most-popular-top-level-domains-in-2017/

That could be addressed by editing the code above to read:

alphabets= "([A-Za-z])"
prefixes = "(Mr|St|Mrs|Ms|Dr)[.]"
suffixes = "(Inc|Ltd|Jr|Sr|Co)"
starters = "(Mr|Mrs|Ms|Dr|He\s|She\s|It\s|They\s|Their\s|Our\s|We\s|But\s|However\s|That\s|This\s|Wherever)"
acronyms = "([A-Z][.][A-Z][.](?:[A-Z][.])?)"
websites = "[.](com|net|org|io|gov|ai|edu|co.uk|ru|info|biz|online)"

I found this sample in Apache's Quickstart Guide. It's for version 4.5:

/**

public class ClientMultipartFormPost {

    public static void main(String[] args) throws Exception {
        if (args.length != 1)  {

                    "/servlets-examples/servlet/RequestInfoExample");

            FileBody bin = new FileBody(new File(args[0]));
            StringBody comment = new StringBody("A binary file of some kind", ContentType.TEXT_PLAIN);

            HttpEntity reqEntity = MultipartEntityBuilder.create()
                    .addPart("bin", bin)
                    .addPart("comment", comment)
                    .build();


            httppost.setEntity(reqEntity);

            System.out.println("executing request " + httppost.getRequestLine());
            CloseableHttpResponse response = httpclient.execute(httppost);
            try {
                System.out.println("----------------------------------------");
                System.out.println(response.getStatusLine());
                HttpEntity resEntity = response.getEntity();
                if (resEntity != null) {
                    System.out.println("Response content length: " + resEntity.getContentLength());
                }
                EntityUtils.consume(resEntity);
            } finally {
                response.close();
            }
        } finally {
            httpclient.close();
        }
    }
}

Here's a very nice Gist that covers all the possible cases: https://gist.github.com/nepsilon/156387acf9e1e72d48fa35c4fabef0b4

Overview:

git rebase -i HEAD~X
# X is the number of commits to go back
# Move to the line of your commit, change pick into edit,
# then change your commit message:
git commit --amend
# Finish the rebase with:
git rebase --continue

The answers to your two questions are related. I'll start with the second:

Once you have staged a file (often with git add, though some other commands implicitly stage the changes as well, like git rm) you can back out that change with git reset -- <file>.

In your case you must have used git rm to remove the file, which is equivalent to simply removing it with rm and then staging that change. If you first unstage it with git reset -- <file> you can then recover it with git checkout -- <file>.

I wrote a simple recursive function to do the job:

from xml.etree import ElementTree
root = ElementTree.XML(xml_to_convert)

def xml_to_dict_recursive(root):

    if len(root.getchildren()) == 0:
        return {root.tag:root.text}
    else:
        return {root.tag:list(map(xml_to_dict_recursive, root.getchildren()))}

You can check if a element is disabled or not with this:

if($("#slcCausaRechazo").prop('disabled') == false)
{
//your code to realice 
}

You should remove the & (ampersand) symbol, so that line 4 will look like this:

$conn = ADONewConnection($config['db_type']);

This is because ADONewConnection already returns an object by reference. As per documentation, assigning the result of a reference to object by reference results in an E_DEPRECATED message as of PHP 5.3.0

I just wanted to add that "Include" is part of eager loading. It is described in Entity Framework 6 tutorial by Microsoft. Here is the link: https://docs.microsoft.com/en-us/aspnet/mvc/overview/getting-started/getting-started-with-ef-using-mvc/reading-related-data-with-the-entity-framework-in-an-asp-net-mvc-application

Excerpt from the linked page:

Here are several ways that the Entity Framework can load related data into the navigation properties of an entity:

Lazy loading. When the entity is first read, related data isn't retrieved. However, the first time you attempt to access a navigation property, the data required for that navigation property is automatically retrieved. This results in multiple queries sent to the database — one for the entity itself and one each time that related data for the entity must be retrieved. The DbContext class enables lazy loading by default.

Eager loading. When the entity is read, related data is retrieved along with it. This typically results in a single join query that retrieves all of the data that's needed. You specify eager loading by using the Include method.

Explicit loading. This is similar to lazy loading, except that you explicitly retrieve the related data in code; it doesn't happen automatically when you access a navigation property. You load related data manually by getting the object state manager entry for an entity and calling the Collection.Load method for collections or the Reference.Load method for properties that hold a single entity. (In the following example, if you wanted to load the Administrator navigation property, you'd replace Collection(x => x.Courses) with Reference(x => x.Administrator).) Typically you'd use explicit loading only when you've turned lazy loading off.

Because they don't immediately retrieve the property values, lazy loading and explicit loading are also both known as deferred loading.

If you are writing a web app or single page application (SPA) where routing takes place in the app/browser rather than a round-trip to the server, you can do the following:

window.history.pushState({ prevUrl: window.location.href }, null, "/new/path/in/your/app")

Then, in your new route, you can do the following to retrieve the previous URL:

window.history.state.prevUrl // your previous url

You need to implement your own Comparator, and then use it: for example

Arrays.sort(persons, new PersonComparator());

Your Comparator could look a bit like this:

public class PersonComparator implements Comparator<? extends Person> {

  public int compare(Person p1, Person p2) {
     int nameCompare = p1.name.compareToIgnoreCase(p2.name);
     if (nameCompare != 0) {
        return nameCompare;
     } else {
       return Integer.valueOf(p1.age).compareTo(Integer.valueOf(p2.age));
     }
  }
}

The comparator first compares the names, if they are not equals it returns the result from comparing them, else it returns the compare result when comparing the ages of both persons.

This code is only a draft: because the class is immutable you could think of building an singleton of it, instead creating a new instance for each sorting.

If this is something you'll need to do often...then you may want to denormalize the relationship between tables A and B.

For example, on insert to table B, you could write zero or more entries to a juncion table mapping B to A based on partial mapping. Similarly, changes to either table could update this association.

This all depends on how frequently tables A and B are modified. If they are fairly static, then taking a hit on INSERT is less painful then repeated hits on SELECT.

wt = tt - cpu tm.
Tt = cpu tm + wt.

Where wt is a waiting time and tt is turnaround time. Cpu time is also called burst time.

-- This is Interview Question asked every time. Now i done its coding.

static void Main(string[] args)
{    
            int[] array = new int[] { 4, 8, 4, 1, 1, 4, 8 };            
            int numDups = 0, prevIndex = 0;

            for (int i = 0; i < array.Length; i++)
            {

                    {
                        foundDup = true;
                        numDups++; // Increment means Count for Duplicate found in array.
                        break;
                    }                    
                }

                if (foundDup == false)
                {
                    array[prevIndex] = array[i];
                    prevIndex++;
                }
            }

            // Just Duplicate records replce by zero.
            for (int k = 1; k <= numDups; k++)
            {               
                array[array.Length - k] = '\0';             
            }


            Console.WriteLine("Console program for Remove duplicates from array.");
            Console.Read();
        }

This is the simplest solution:

SELECT quote FROM quotes ORDER BY RAND() 

Although it is not the most efficient. This one is a better solution.

Here are two functions to get the page height and the scroll amounts (x,y) without the use of the (bloated) dimensions plugin:

// getPageScroll() by quirksmode.com
function getPageScroll() {
    var xScroll, yScroll;
    if (self.pageYOffset) {
      yScroll = self.pageYOffset;
      xScroll = self.pageXOffset;
    } else if (document.documentElement && document.documentElement.scrollTop) {
      yScroll = document.documentElement.scrollTop;
      xScroll = document.documentElement.scrollLeft;
    } else if (document.body) {// all other Explorers
      yScroll = document.body.scrollTop;
      xScroll = document.body.scrollLeft;
    }
    return new Array(xScroll,yScroll)
}

// Adapted from getPageSize() by quirksmode.com
function getPageHeight() {
    var windowHeight
    if (self.innerHeight) { // all except Explorer
      windowHeight = self.innerHeight;
    } else if (document.documentElement && document.documentElement.clientHeight) {
      windowHeight = document.documentElement.clientHeight;
    } else if (document.body) { // other Explorers
      windowHeight = document.body.clientHeight;
    }
    return windowHeight
}

It seems that ssh cannot read your public key. But that doesn't matter.

You upload your public key to github, but you authenticate using your private key. See e.g. the FILES section in ssh(1).

First, remove all explicit setting of modal presentation style in code and do the following:

1. In the storyboard set the ModalViewController's modalPresentation style to Over Current context

2. Check the checkboxes in the Root/Presenting ViewController - Provide Context and Define Context. They seem to be working even unchecked.

from a Debug Keystore we can get the SHA1 value in Eclipse. Accessing from the menu: Window -> Preferences -> Android -> Build

but it doesn´t work for a production Keystore.

So, to get the SHA1 value from a production Keystore go to: Android Tools -> Export Signed Application Package. Follow the process for signing your apk and the SHA1 will showed as a certificate.

Most escape characters in string literals from Java are also valid in Python, such as "\r" and "\n".

From the document.getElementsByTagName I guess you are running the javascript in a browser.

The traditional way to expose functionality to javascript running in the browser is calling a remote URL using AJAX. The X in AJAX is for XML, but nowadays everybody uses JSON instead of XML.

For example, using jQuery you can do something like:

$.getJSON('http://example.com/your/webservice?param1=x&param2=y', 
    function(data, textStatus, jqXHR) {
        alert(data);
    }
)

You will need to implement a python webservice on the server side. For simple webservices I like to use Flask.

A typical implementation looks like:

@app.route("/your/webservice")
def my_webservice():
    return jsonify(result=some_function(**request.args)) 

You can run IronPython (kind of Python.Net) in the browser with silverlight, but I don't know if NLTK is available for IronPython.

Check if password you are using is correct one by running below command

keytool -keypasswd -new temp123 -keystore awsdemo-keystore.jks -storepass temp123 -alias movie-service -keypass changeit

If you are getting below error then your password is wrong

keytool error: java.security.UnrecoverableKeyException: Cannot recover key

From the session_destroy() page in the PHP manual:

<?php
// Initialize the session.
// If you are using session_name("something"), don't forget it now!
session_start();

// Unset all of the session variables.
$_SESSION = array();

// If it's desired to kill the session, also delete the session cookie.
// Note: This will destroy the session, and not just the session data!
if (ini_get("session.use_cookies")) {
    $params = session_get_cookie_params();
    setcookie(session_name(), '', time() - 42000,
        $params["path"], $params["domain"],
        $params["secure"], $params["httponly"]
    );
}

// Finally, destroy the session.
session_destroy();
?>

It would have worked out of the box if you hadn't used @EnableWebMvc annotation. When you do that you switch off all the things that Spring Boot does for you in WebMvcAutoConfiguration. You could remove that annotation, or you could add back the view controller that you switched off:

@Override
public void addViewControllers(ViewControllerRegistry registry) {
    registry.addViewController("/").setViewName("forward:/index.html");
}

I was able to log on to the mysql server after running the command @robregonm suggested:

mysql_upgrade -u root -p --force

A MySQL server restart is required.

This solution is HTML and CSS based using z-index and hover, which works if JS is disabled or the video isn't yours (since you can add a thumbnail in YouTube).

<style>
.videoWrapper {
  position: relative;
  padding-bottom: 56.25%;
}
.videoWrapper .video-modal-poster img {
  position: absolute;
  width: 100%;
  height: 100%;
  top: 0;
  left: 0;
  z-index: 10;
}
.videoWrapper .video-modal-poster:hover img {
  z-index:0;
}
.videoWrapper iframe {
  position: absolute;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  z-index: 1;
}
</style>
<div class="videoWrapper">

This is how I would do it, in order to get in the var4 restriction:

dfr<-data.frame(var1=rnorm(100), var2=rnorm(100), var3=rnorm(100, 160, 10), var4=rnorm(100, 27, 6))
plot( subset( dfr, var3 < 155 & var4 > 27, select = c( var1, var2 ) ) )

[your Array name] = Empty

Then the array will be without content and can be filled again.

I just had the same problem as you, but found out about the toDataURL method, which proved useful.

The gist of it is to turn your current canvas into a dataURL, change your canvas size, and then draw what you had back into your canvas from the dataURL you saved.

So here's my code:

var oldCanvas = canvas.toDataURL("image/png");
var img = new Image();
img.src = oldCanvas;
img.onload = function (){
    canvas.height += 100;
    ctx.drawImage(img, 0, 0);
}

You can try to add some time.sleep calls to your code.

It seems like the server side limits the amount of requests per timeunit (hour, day, second) as a security issue. You need to guess how many (maybe using another script with a counter?) and adjust your script to not surpass this limit.

In order to avoid your code from crashing, try to catch this error with try .. except around the urllib2 calls.

You can use:

System.Net.Dns.GetHostEntry(System.Net.Dns.GetHostName()).AddressList.GetValue(0).ToString();

No you don't have to put credentials, You have to put headers on client side eg:

 $http({
        url: 'url of service',
        method: "POST",
        data: {test :  name },
        withCredentials: true,
        headers: {
                    'Content-Type': 'application/json; charset=utf-8'
        }
    });

And and on server side you have to put headers to this is example for nodejs:

/**
 * On all requests add headers
 */
app.all('*', function(req, res,next) {


    /**
     * Response settings
     * @type {Object}
     */
    var responseSettings = {
        "AccessControlAllowOrigin": req.headers.origin,
        "AccessControlAllowHeaders": "Content-Type,X-CSRF-Token, X-Requested-With, Accept, Accept-Version, Content-Length, Content-MD5,  Date, X-Api-Version, X-File-Name",
        "AccessControlAllowMethods": "POST, GET, PUT, DELETE, OPTIONS",
        "AccessControlAllowCredentials": true
    };

    /**
     * Headers
     */
    res.header("Access-Control-Allow-Credentials", responseSettings.AccessControlAllowCredentials);
    res.header("Access-Control-Allow-Origin",  responseSettings.AccessControlAllowOrigin);
    res.header("Access-Control-Allow-Headers", (req.headers['access-control-request-headers']) ? req.headers['access-control-request-headers'] : "x-requested-with");
    res.header("Access-Control-Allow-Methods", (req.headers['access-control-request-method']) ? req.headers['access-control-request-method'] : responseSettings.AccessControlAllowMethods);

    if ('OPTIONS' == req.method) {
        res.send(200);
    }
    else {
        next();
    }


});

You could use this jQuery plugin: https://github.com/mathiasbynens/jquery-placeholder

But your link seems to be also a good solution.

I've found a solution for me with Spring and jackson

First specify the filter name in the entity

@Entity
@Table(name = "SECTEUR")
@JsonFilter(ModelJsonFilters.SECTEUR_FILTER)
public class Secteur implements Serializable {

/** Serial UID */
private static final long serialVersionUID = 5697181222899184767L;

/**
 * Unique ID
 */
@Id
@JsonView(View.SecteurWithoutChildrens.class)
@Column(name = "id")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private long id;

@JsonView(View.SecteurWithoutChildrens.class)
@Column(name = "code", nullable = false, length = 35)
private String code;

/**
 * Identifiant du secteur parent
 */
@JsonView(View.SecteurWithoutChildrens.class)
@Column(name = "id_parent")
private Long idParent;

@OneToMany(fetch = FetchType.LAZY)
@JoinColumn(name = "id_parent")
private List<Secteur> secteursEnfants = new ArrayList<>(0);

}

Then you can see the constants filters names class with the default FilterProvider used in spring configuration

public class ModelJsonFilters {

public final static String SECTEUR_FILTER = "SecteurFilter";
public final static String APPLICATION_FILTER = "ApplicationFilter";
public final static String SERVICE_FILTER = "ServiceFilter";
public final static String UTILISATEUR_FILTER = "UtilisateurFilter";

public static SimpleFilterProvider getDefaultFilters() {
    SimpleBeanPropertyFilter theFilter = SimpleBeanPropertyFilter.serializeAll();
    return new SimpleFilterProvider().setDefaultFilter(theFilter);
}

}

Spring configuration :

@EnableWebMvc
@Configuration
@ComponentScan(basePackages = "fr.sodebo")

public class ApiRootConfiguration extends WebMvcConfigurerAdapter {

@Autowired
private EntityManagerFactory entityManagerFactory;


/**
 * config qui permet d'éviter les "Lazy loading Error" au moment de la
 * conversion json par jackson pour les retours des services REST<br>
 * on permet à jackson d'acceder à sessionFactory pour charger ce dont il a
 * besoin
 */
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {

    super.configureMessageConverters(converters);
    MappingJackson2HttpMessageConverter converter = new MappingJackson2HttpMessageConverter();
    ObjectMapper mapper = new ObjectMapper();

    // config d'hibernate pour la conversion json
    mapper.registerModule(getConfiguredHibernateModule());//

    // inscrit les filtres json
    subscribeFiltersInMapper(mapper);

    // config du comportement de json views
    mapper.configure(MapperFeature.DEFAULT_VIEW_INCLUSION, false);

    converter.setObjectMapper(mapper);
    converters.add(converter);
}

/**
 * config d'hibernate pour la conversion json
 * 
 * @return Hibernate5Module
 */
private Hibernate5Module getConfiguredHibernateModule() {
    SessionFactory sessionFactory = entityManagerFactory.unwrap(SessionFactory.class);
    Hibernate5Module module = new Hibernate5Module(sessionFactory);
    module.configure(Hibernate5Module.Feature.FORCE_LAZY_LOADING, true);

    return module;

}

/**
 * inscrit les filtres json
 * 
 * @param mapper
 */
private void subscribeFiltersInMapper(ObjectMapper mapper) {

    mapper.setFilterProvider(ModelJsonFilters.getDefaultFilters());

}

}

Endly I can specify a specific filter in restConstoller when i need....

@RequestMapping(value = "/{id}/droits/", method = RequestMethod.GET)
public MappingJacksonValue getListDroits(@PathVariable long id) {

    LOGGER.debug("Get all droits of user with id {}", id);

    List<Droit> droits = utilisateurService.findDroitsDeUtilisateur(id);

    MappingJacksonValue value;

    UtilisateurWithSecteurs utilisateurWithSecteurs = droitsUtilisateur.fillLists(droits).get(id);

    value = new MappingJacksonValue(utilisateurWithSecteurs);

    FilterProvider filters = ModelJsonFilters.getDefaultFilters().addFilter(ModelJsonFilters.SECTEUR_FILTER, SimpleBeanPropertyFilter.serializeAllExcept("secteursEnfants")).addFilter(ModelJsonFilters.APPLICATION_FILTER,
            SimpleBeanPropertyFilter.serializeAllExcept("services"));

    value.setFilters(filters);
    return value;

}

If you try to open a TCP connection to another host and see the error "Connection refused," it means that

1. You sent a TCP SYN packet to the other host.
2. Then you received a TCP RST packet in reply.

RST is a bit on the TCP packet which indicates that the connection should be reset. Usually it means that the other host has received your connection attempt and is actively refusing your TCP connection, but sometimes an intervening firewall may block your TCP SYN packet and send a TCP RST back to you.

See https://tools.ietf.org/html/rfc793 page 69:

SYN-RECEIVED STATE

If the RST bit is set

If this connection was initiated with a passive OPEN (i.e., came from the LISTEN state), then return this connection to LISTEN state and return. The user need not be informed. If this connection was initiated with an active OPEN (i.e., came from SYN-SENT state) then the connection was refused, signal the user "connection refused". In either case, all segments on the retransmission queue should be removed. And in the active OPEN case, enter the CLOSED state and delete the TCB, and return.

Nothing elegant but this could be another satisfactory answer.

merge(x = DF1, y = DF2, by = "Client", all.x=TRUE)[,c("Client","LO","CON")]

This will be useful especially when you don't need the keys that were used to join the tables in your results.

A PDOStatement (which you have in $users) is a forward-cursor. That means, once consumed (the first foreach iteration), it won't rewind to the beginning of the resultset.

You can close the cursor after the foreach and execute the statement again:

$users       = $dbh->query($sql);
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}

$users->execute();

foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}

Or you could cache using tailored CachingIterator with a fullcache:

$users       = $dbh->query($sql);

$usersCached = new CachedPDOStatement($users);

foreach ($usersCached as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}
foreach ($usersCached as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}

You find the CachedPDOStatement class as a gist. The caching itertor is probably more sane than storing the resultset into an array because it still offers all properties and methods of the PDOStatement object it has wrapped.

You need to use the SUBTOTAL function. The SUBTOTAL function ignores rows that have been excluded by a filter.

The formula would look like this:

=SUBTOTAL(9,B1:B20)

The function number 9, tells it to use the SUM function on the data range B1:B20.

If you are 'filtering' by hiding rows, the function number should be updated to 109.

=SUBTOTAL(109,B1:B20)

The function number 109 is for the SUM function as well, but hidden rows are ignored.

You need to make sure that your project is set to target the AVD that you want to launch.

Right click (ctrl-click MAC) on the project folder in Eclipse. Then click on Properties. In the window that shows up, click on "Android" and then click on the build target you want to launch. Hope that helps.

If you want smooth blinking text or something a like you can use following code:

 .blinking {
    -webkit-animation: 1s blink ease infinite;
    -moz-animation: 1s blink ease infinite;
    -ms-animation: 1s blink ease infinite;
    -o-animation: 1s blink ease infinite;
    animation: 1s blink ease infinite;
  }

  @keyframes "blink" {

    from,
    to {
      opacity: 0;
    }

    50% {
      opacity: 1;
    }
  }

  @-moz-keyframes blink {

    from,
    to {
      opacity: 0;
    }

    50% {
      opacity: 1;
    }
  }

  @-webkit-keyframes "blink" {

    from,
    to {
      opacity: 0;
    }

    50% {
      opacity: 1;
    }
  }

  @-ms-keyframes "blink" {

    from,
    to {
      opacity: 0;
    }

    50% {
      opacity: 1;
    }
  }

  @-o-keyframes "blink" {

    from,
    to {
      opacity: 0;
    }

    50% {
      opacity: 1;
    }
  }

<span class="blinking">I am smoothly blinking</span>

1 additional caveat (besides the answer by kanaka/peter): if you use WSS, and the server certificate is not acceptable to the browser, you may not get any browser rendered dialog (like it happens for Web pages). This is because WebSockets is treated as a so-called "subresource", and certificate accept / security exception / whatever dialogs are not rendered for subresources.

To get a position of an element in a vector knowing an iterator pointing to the element, simply subtract v.begin() from the iterator:

ptrdiff_t pos = find(Names.begin(), Names.end(), old_name_) - Names.begin();

Now you need to check pos against Names.size() to see if it is out of bounds or not:

if(pos >= Names.size()) {
    //old_name_ not found
}

vector iterators behave in ways similar to array pointers; most of what you know about pointer arithmetic can be applied to vector iterators as well.

Starting with C++11 you can use std::distance in place of subtraction for both iterators and pointers:

ptrdiff_t pos = distance(Names.begin(), find(Names.begin(), Names.end(), old_name_));

yourElement.setAttribute("style", "background-color:red; font-size:2em;");

Or you could write the element as pure HTML and use .innerHTML = [raw html code]... that's very ugly though.

In answer to your first question, first you use var myElement = createElement(...);, then you do document.body.appendChild(myElement);.

It seems things were designed to avoid developers to se the root user, a better solution would be:

sudo mysql -u root

Then create a normal user, set a password, then use that user to work.

create user 'user'@'localhost' identified by 'user1234';
grant all on your_database.* to 'user'@'localhost';
select host, user from mysql.user;

Then try to access:

mysql -u user -p

Boom!

This may not be relevant to your specific issue, but I had a similar problem when the pickle archive had been created using gzip.

For example if a compressed pickle archive is made like this,

import gzip, pickle
with gzip.open('test.pklz', 'wb') as ofp:
    pickle.dump([1,2,3], ofp)

Trying to open it throws the errors

 with open('test.pklz', 'rb') as ifp:
     print(pickle.load(ifp))
Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
_pickle.UnpicklingError: invalid load key, ''.

But, if the pickle file is opened using gzip all is harmonious

with gzip.open('test.pklz', 'rb') as ifp:
    print(pickle.load(ifp))

The answer from Pragna does not work always, try this:

mScrollView.post(new Runnable() { 
        public void run() { 
             mScrollView.scrollTo(0, mScrollView.getBottom());
        } 
});

or

mScrollView.post(new Runnable() { 
        public void run() { 
             mScrollView.fullScroll(mScrollView.FOCUS_DOWN);
        } 
});

if You want to scroll to start

mScrollView.post(new Runnable() { 
        public void run() { 
             mScrollView.fullScroll(mScrollView.FOCUS_UP);
        } 
});

Change the project interpreter to ~/anaconda2/python/bin by going to File -> Settings -> Project -> Project Interpreter. Also update the run configuration to use the project default Python interpreter via Run -> Edit Configurations. This makes PyCharm use Anaconda instead of the default Python interpreter under usr/bin/python27.

You can also plot the timestamp, value pairs using pyplot.plot (after parsing them from their string representation). (Tested with matplotlib versions 1.2.0 and 1.3.1.)

Example:

import datetime
import random
import matplotlib.pyplot as plt

# make up some data
x = [datetime.datetime.now() + datetime.timedelta(hours=i) for i in range(12)]
y = [i+random.gauss(0,1) for i,_ in enumerate(x)]

# plot
plt.plot(x,y)
# beautify the x-labels
plt.gcf().autofmt_xdate()

plt.show()

Resulting image:

Here's the same as a scatter plot:

import datetime
import random
import matplotlib.pyplot as plt

# make up some data
x = [datetime.datetime.now() + datetime.timedelta(hours=i) for i in range(12)]
y = [i+random.gauss(0,1) for i,_ in enumerate(x)]

# plot
plt.scatter(x,y)
# beautify the x-labels
plt.gcf().autofmt_xdate()

plt.show()

Produces an image similar to this:

You do not need to call d.keys(), so

if key not in d:
    d[key] = value

is enough. There is no clearer, more readable method.

You could update again with dict.get(), which would return an existing value if the key is already present:

d[key] = d.get(key, value)

but I strongly recommend against this; this is code golfing, hindering maintenance and readability.

As mentioned before, you cannot create free certificates for S3 buckets. However, you can create Cloud Front distribution and then assign the certificate for the Cloud Front instead. You request the certificate for your domain and then just assign it to the Cloud Front distribution in the Cloud Front settings. I've used this method to serve static websites via SSL as well as serve static files.

For static website creation Amazon is the go to place. It is really affordable to get a static website with SSL.

This works good for me. I have divided the screen into two halfs: 20% and 80%:

<div style="width: 20%; float:left">
   #left content in here
</div>

<div style="width: 80%; float:right">
   #right content in there
</div>

Comparing by performance the winner is "Loop it, sb.Append it, and do back step". Actually "enumerable and manual move next" is the same good (consider stddev).

Promises

1. Definition: Helps you run functions asynchronously, and use their return values (or exceptions) but only once when executed.
2. Not Lazy
3. Not cancellable( There are Promise libraries out there that support cancellation, but ES6 Promise doesn't so far). The two possible decisions are
   • Reject
   • Resolve
4. Cannot be retried(Promises should have access to the original function that returned the promise to have a retry capability, which is a bad practice)

Observables

1. Definition: Helps you run functions asynchronously, and use their return values in a continuous sequence(multiple times) when executed.
2. By default, it is Lazy as it emits values when time progresses.
3. Has a lot of operators which simplifies the coding effort.

4. One operator retry can be used to retry whenever needed, also if we need to retry the observable based on some conditions retryWhen can be used.

   Note: A list of operators along with their interactive diagrams is available here at RxMarbles.com

One obvious and straightforward possibility is to use "if-else conditions". In that example

x <- c(1, 2, 4)
y <- c(1, 4, 5)
w <- ifelse(x <= 1, "good", ifelse((x >= 3) & (x <= 5), "bad", "fair"))
data.frame(x, y, w)

** For the additional question in the edit** Is that what you expect ?

> d1 <- c("e", "c", "a")
> d2 <- c("e", "a", "b")
> 
> w <- ifelse((d1 == "e") & (d2 == "e"), 1, 
+    ifelse((d1=="a") & (d2 == "b"), 2,
+    ifelse((d1 == "e"), 3, 99)))
>     
> data.frame(d1, d2, w)
  d1 d2  w
1  e  e  1
2  c  a 99
3  a  b  2

If you do not feel comfortable with the ifelse function, you can also work with the if and else statements for such applications.

Trying to run a servlet in Eclipse (right-click + "Run on Server") I encountered the very same problem: "HTTP Status: 404 / Description: The origin server did not find a current representation for the target resource or is not willing to disclose that one exists." Adding an index.html did not help, neither changing various settings of the tomcat.

Finally, I found the problem in an unexpected place: In Eclipse, the Option "Build automatically" was not set. Thus the servlet was not compiled, and no File "myServlet.class" was deployed to the server (in my case in the path .wtpwebapps/projectXX/WEB-INF/classes/XXpackage/). Building the project manually and restarting the server solved the problem.

My environment: Eclipse Neon.3 Release 4.6.3, Tomcat-Version 8.5.14., OS Linux Mint 18.1.

Setting time interval to check for fix is not a good choice.. i noticed that onLocationChanged is not called if you are not moving.. what is understandable since location is not changing :)

Better way would be for example:

• check interval to last location received (in gpsStatusChanged)
• if that interval is more than 15s set variable: long_interval = true
• remove the location listener and add it again, usually then you get updated position if location really is available, if not - you probably lost location
• in onLocationChanged you just set long_interval to false..

You can able to download Xcode DMG file from the

To give a more up-to-date approach to this:

//one-time fire
element.addEventListener('mousedown', {
  handleEvent: function (evt) {
    element.removeEventListener(evt.type, this, false);
  }
}, false);

I think it is platform dependent. When developing in .Net MVC, I use bootstrap style lower case and hyphens for class names, but for ids I use PascalCase.

The reasoning for this is that my views are backed by strongly typed view models. Properties of C# models are pascal case. For the sake of model binding with MVC it makes sense that the names of HTML elements that bind to the model are consistent with the view model properties which are pascal case. For simplicity my ids are use the same naming convention as element names except for radio buttons and check boxes which require unique ids for each element in the named input group.

Add jQuery JavaScript library together with the jquery.zbox.css and jquery.zbox.js to your webpage.

<link rel="stylesheet" href="jquery.zbox.css">
<script src="jquery.min.js"></script>
<script src="jquery.zbox.min.js"></script>

Add a group of thumbnails with links pointing to the full sized images into the webpage.

<a class="zb" rel="group" href="1.png" title="Image 1">
  <img src="thumb1.png">
</a>
<a class="zb" rel="group" href="2.png" title="Image 2">
  <img src="thumb2.png">
</a>
<a class="zb" rel="group" href="3.png" title="Image 3">
 <img src="thumb3.png">
</a>

Call the function on document ready. That's it.

In the view source do:

$(".zb").zbox();

You are checking Parent properties for null in your delegate. The same should work with lambda expressions too.

List<AnalysisObject> analysisObjects = analysisObjectRepository
        .FindAll()
        .Where(x => 
            (x.ID == packageId) || 
            (x.Parent != null &&
                (x.Parent.ID == packageId || 
                (x.Parent.Parent != null && x.Parent.Parent.ID == packageId)))
        .ToList();

Not exact answer but a simpler alternative:

• Place another view on top of the image
• Change the alpha value of the view however you want (programmatically) to get the desired effect.

Here is a snippet for that:

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="@dimen/height120"
        android:contentDescription="@string/my_description"
        android:scaleType="fitXY"
        android:src="@drawable/my_awesome_image"/>

    <View
        android:layout_width="match_parent"
        android:layout_height="@dimen/height120"
        android:alpha="0.5"
        android:background="@color/my_blue_color"/>
</FrameLayout>

Hope this will help to someone. Works fine in Angular 6 with reactive forms. Can operate by keyboard too.

Usage

<app-dropdown formControlName="type" [options]="types" [placeholder]="captureData.type" [isReadOnly]="isReadOnly">
</app-dropdown>

Options must bind an array as follows. It can change based on the requirement.

types= [
        {
            "id": "1",
            "value": "Type 1"
        },
        {
             "id": "2",
             "value": "Type 2"
        },
        {
              "id": "3",
              "value": "Type 3"
        }] 

From your log its clear that numpy package is missing. As mention in the PyPI package:

The SciPy library depends on NumPy, which provides convenient and fast N-dimensional array manipulation.

So, try installing numpy package for python as you did with scipy.

In addition to the steps provided by @asfsafgsf (above), make sure to re-enable your phone's developer modes/functions. For my Motorola Atrix:

• settings>applications>Unknown Sources: allow 3rd party apps
• settings>applications>Development: to enable USB debugging, mock locations, and disable phone sleep

A note on developer modes

USB Debugging is the main mode you will need for running apps through eclipse when your phone is connected via usb (obviously). Disable phone sleep is also handy for self-explanatory reasons.

Allowing 3rd party app sources allows you to beta test your app on a larger-scale. With this, you can host your own apk and instruct your beta-testers to download it (prior to releasing it to the Google Play storefront). More specifically, 3rd party support allows the installation of android package files that don't contain a google approved signature (required for play store hosting). With 3rd party apps enabled, a handset will be able to run packages regardless of their source. You should also be able to receive an APK via bluetooth and install it in this mode.

The :: operator is called the scope-resolution operator and does just that, it resolves scope. So, by prefixing a type-name with this, it tells your compiler to look in the global namespace for the type.

Example:

int count = 0;

int main(void) {
  int count = 0;
  ::count = 1;  // set global count to 1
  count = 2;    // set local count to 2
  return 0;
}

The problem is that in IE (which is what I presume you're testing in), the <iframe> element has a document property that refers to the document containing the iframe, and this is getting used before the contentDocument or contentWindow.document properties. What you need is:

function GetDoc(x) {
    return x.contentDocument || x.contentWindow.document;
}

Also, document.all is not available in all browsers and is non-standard. Use document.getElementById() instead.

This was asked on the www-style list, and Tab Atkins (spec editor) provided an answer explaining why. I'll elaborate on that a bit here.

To start out, let's initially assume our flex container is single-line (flex-wrap: nowrap). In this case, there's clearly an alignment difference between the main axis and the cross axis -- there are multiple items stacked in the main axis, but only one item stacked in the cross axis. So it makes sense to have a customizeable-per-item "align-self" in the cross axis (since each item is aligned separately, on its own), whereas it doesn't make sense in the main axis (since there, the items are aligned collectively).

For multi-line flexbox, the same logic applies to each "flex line". In a given line, items are aligned individually in the cross axis (since there's only one item per line, in the cross axis), vs. collectively in the main axis.

Here's another way of phrasing it: so, all of the *-self and *-content properties are about how to distribute extra space around things. But the key difference is that the *-self versions are for cases where there's only a single thing in that axis, and the *-content versions are for when there are potentially many things in that axis. The one-thing vs. many-things scenarios are different types of problems, and so they have different types of options available -- for example, the space-around / space-between values make sense for *-content, but not for *-self.

SO: In a flexbox's main axis, there are many things to distribute space around. So a *-content property makes sense there, but not a *-self property.

In contrast, in the cross axis, we have both a *-self and a *-content property. One determines how we'll distribute space around the many flex lines (align-content), whereas the other (align-self) determines how to distribute space around individual flex items in the cross axis, within a given flex line.

(I'm ignoring *-items properties here, since they simply establish defaults for *-self.)

One option would be:

SET SERVEROUTPUT ON

EXEC DBMS_OUTPUT.PUT_LINE(your_fn_name(your_fn_arguments));

This has changed, it's now fb://profile/(profileID)

Local fonts linking to your react js may be a failure. So, I prefer to use online css file from google to link fonts. Refer the following code,

<link href="https://fonts.googleapis.com/css?family=Roboto" rel="stylesheet">

or

<style>
    @import url('https://fonts.googleapis.com/css?family=Roboto');
</style>

Many DNS servers refuse ‘ANY’ queries. So the only way is to query for every type individually. Luckily there are sites that make this simpler. For example, https://www.nslookup.io shows the most popular record types by default, and has support for all existing record types.

Promise returned from $http can not be binded directly (I dont exactly know why). I'm using wrapping service that works perfectly for me:

.factory('DocumentsList', function($http, $q){
    var d = $q.defer();
    $http.get('/DocumentsList').success(function(data){
        d.resolve(data);
    });
    return d.promise;
});

and bind to it in controller:

function Ctrl($scope, DocumentsList) {
    $scope.Documents = DocumentsList;
    ...
}

UPDATE!:

In Angular 1.2 auto-unwrap promises was removed. See http://docs.angularjs.org/guide/migration#templates-no-longer-automatically-unwrap-promises

I made a bit more of a generic filter that I've used in multiple projects already:

• object = the object that needs to be filtered
• field = the field within that object that we'll filter on
• filter = the value of the filter that needs to match the field

HTML:

<input ng-model="customerNameFilter" />
<div ng-repeat="(key, value) in filter(customers, 'customerName', customerNameFilter" >
   <p>Number: {{value.customerNo}}</p>
   <p>Name: {{value.customerName}}</p>
</div>

JS:

  $scope.filter = function(object, field, filter) {
    if (!object) return {};
    if (!filter) return object;

    var filteredObject = {};
    Object.keys(object).forEach(function(key) {
      if (object[key][field] === filter) {
        filteredObject[key] = object[key];
      }
    });

    return filteredObject;
  };

More compact way to get the difference between two datetime objects and then convert the difference into seconds is shown below (Python 3x):

from datetime import datetime
        
time1 = datetime.strftime('18 01 2021', '%d %m %Y')
    
time2 = datetime.strftime('19 01 2021', '%d %m %Y')

difference = time2 - time1

difference_in_seconds = difference.total_seconds()

You are checking it the array index contains a string "undefined", you should either use the typeof operator:

typeof predQuery[preId] == 'undefined'

Or use the undefined global property:

predQuery[preId] === undefined

The first way is safer, because the undefined global property is writable, and it can be changed to any other value.

SELECT a.table_name, a.column_name, a.constraint_name, c.owner, 
       -- referenced pk
       c.r_owner, c_pk.table_name r_table_name, c_pk.constraint_name r_pk
  FROM all_cons_columns a
  JOIN all_constraints c ON a.owner = c.owner
                        AND a.constraint_name = c.constraint_name
  JOIN all_constraints c_pk ON c.r_owner = c_pk.owner
                           AND c.r_constraint_name = c_pk.constraint_name
 WHERE c.constraint_type = 'R'
   AND a.table_name :=TABLE_NAME
   AND c.owner :=OWNER_NAME;

One clean way to do this is to inject VirtualTime. It allows you to control time. First install VirtualTime

Install-Package VirtualTime

That allows to, for example, make time that moves 5 times faster on all calls to DateTime.Now or UtcNow

var DateTime = DateTime.Now.ToVirtualTime(5);

To make time move slower , eg 5 times slower do

var DateTime = DateTime.Now.ToVirtualTime(0.5);

To make time stand still do

var DateTime = DateTime.Now.ToVirtualTime(0);

Moving backwards in time is not tested yet

Here are a sample test:

[TestMethod]
public void it_should_make_time_move_faster()
{
    int speedOfTimePerMs = 1000;
    int timeToPassMs = 3000;
    int expectedElapsedVirtualTime = speedOfTimePerMs * timeToPassMs;
    DateTime whenTimeStarts = DateTime.Now;
    ITime time = whenTimeStarts.ToVirtualTime(speedOfTimePerMs);
    Thread.Sleep(timeToPassMs);
    DateTime expectedTime = DateTime.Now.AddMilliseconds(expectedElapsedVirtualTime - timeToPassMs);
    DateTime virtualTime = time.Now;

    Assert.IsTrue(TestHelper.AreEqualWithinMarginOfError(expectedTime, virtualTime, MarginOfErrorMs));
}

You can check out more tests here:

https://github.com/VirtualTime/VirtualTime/blob/master/VirtualTimeLib.Tests/when_virtual_time_is_used.cs

What DateTime.Now.ToVirtualTime extension gives you is an instance of ITime which you pass to a method / class that depends on ITime. some DateTime.Now.ToVirtualTime is setup in the DI container of your choice

Here is another example injecting into a class contrustor

public class AlarmClock
{
    private ITime DateTime;
    public AlarmClock(ITime dateTime, int numberOfHours)
    {
        DateTime = dateTime;
        SetTime = DateTime.UtcNow.AddHours(numberOfHours);
        Task.Run(() =>
        {
            while (!IsAlarmOn)
            {
                IsAlarmOn = (SetTime - DateTime.UtcNow).TotalMilliseconds < 0;
            }
        });
    }
    public DateTime SetTime { get; set; }
    public bool IsAlarmOn { get; set; }
}

[TestMethod]
public void it_can_be_injected_as_a_dependency()
{
    //virtual time has to be 1000*3.75 faster to get to an hour 
    //in 1000 ms real time
    var dateTime = DateTime.Now.ToVirtualTime(1000 * 3.75);
    var numberOfHoursBeforeAlarmSounds = 1;
    var alarmClock = new AlarmClock(dateTime, numberOfHoursBeforeAlarmSounds);
    Assert.IsFalse(alarmClock.IsAlarmOn);
    System.Threading.Thread.Sleep(1000);
    Assert.IsTrue(alarmClock.IsAlarmOn);
}

Building from Ben's plugin this version handles select and you can pass an option to allowSubmit. ie. $("#form").enterAsTab({ 'allowSubmit': true}); This will allow enter to submit the form if the submit button is handling the event.

(function( $ ){
    $.fn.enterAsTab = function( options ) {  
    var settings = $.extend( {
       'allowSubmit': false
    }, options);
    this.find('input, select').live("keypress", {localSettings: settings}, function(event) {
        if (settings.allowSubmit) {
        var type = $(this).attr("type");
        if (type == "submit") {
            return true;
        } 
    }
    if (event.keyCode == 13 ) {
        var inputs =   $(this).parents("form").eq(0).find(":input:visible:not(disabled):not([readonly])");
        var idx = inputs.index(this);
        if (idx == inputs.length - 1) {
           idx = -1;
       } else {
           inputs[idx + 1].focus(); // handles submit buttons
      }
        try {
            inputs[idx + 1].select();
            }
        catch(err) {
            // handle objects not offering select
            }
        return false;
    }
});
  return this;
};
})( jQuery );

Environment variables (that you modify using the System Properties) are only propagated to subshells when you create a new subshell.

If you had a command line prompt (DOS or cygwin) open when you changed the User env vars, then they won't show up.

You need to open a new command line prompt after you change the user settings.

The equivalent in Unix/Linux is adding a line to your .bash_rc: you need to start a new shell to get the values.

Doesn't allow duplicates in the sense, It allow to add you but it does'nt care about this key already have a value or not. So at present for one key there will be only one value

It silently overrides the value for null key. No exception.

When you try to get, the last inserted value with null will be return.

That is not only with null and for any key.

Have a quick example

   Map m = new HashMap<String, String>();
   m.put("1", "a");
   m.put("1", "b");  //no exception
   System.out.println(m.get("1")); //b

For anything with requests to URLs you might want to check out requests. For JSON in particular:

>>> import requests
>>> r = requests.get('https://github.com/timeline.json')
>>> r.json()
[{u'repository': {u'open_issues': 0, u'url': 'https://github.com/...

Amazingly, Unix and Linux do not actually have a place to set global environment variables. The best you can do is arrange for any specific shell to have a site-specific initialization.

If you put it in /etc/profile, that will take care of things for most posix-compatible shell users. This is probably "good enough" for non-critical purposes.

But anyone with a csh or tcsh shell won't see it, and I don't believe csh has a global initialization file.

Here's a twist on @user65157's answer (+1 for that, BTW):

I created an IDisposable wrapper for the pinned object:

class AutoPinner : IDisposable
{
   GCHandle _pinnedArray;
   public AutoPinner(Object obj)
   {
      _pinnedArray = GCHandle.Alloc(obj, GCHandleType.Pinned);
   }
   public static implicit operator IntPtr(AutoPinner ap)
   {
      return ap._pinnedArray.AddrOfPinnedObject(); 
   }
   public void Dispose()
   {
      _pinnedArray.Free();
   }
}

then use it like thusly:

using (AutoPinner ap = new AutoPinner(MyManagedObject))
{
   UnmanagedIntPtr = ap;  // Use the operator to retrieve the IntPtr
   //do your stuff
}

I found this to be a nice way of not forgetting to call Free() :)

style="overflow: hidden" and style="resize: none" were the ones that did the trick.

I am using 0.56RC secureTextEntry={true} Along with password={true} then only its working as mentioned by @NicholasByDesign

The folder containing your Anaconda installation contains a subfolder called conda-meta with json files for all installed packages, including one for Anaconda itself. Look for anaconda-<version>-<build>.json.

My file is called anaconda-5.0.1-py27hdb50712_1.json, and at the bottom is more info about the version:

"installed_by": "Anaconda2-5.0.1-Windows-x86_64.exe", 
"link": { "source": "C:\\ProgramData\\Anaconda2\\pkgs\\anaconda-5.0.1-py27hdb50712_1" }, 
"name": "anaconda", 
"platform": "win", 
"subdir": "win-64", 
"url": "https://repo.continuum.io/pkgs/main/win-64/anaconda-5.0.1-py27hdb50712_1.tar.bz2", 
"version": "5.0.1"

(Slightly edited for brevity.)

The output from conda -V is the conda version.

My JDK is installed at C:\Program Files\Java\jdk1.8.0_144\.
I had set JAVA_HOME= C:\Program Files\Java\jdk1.8.0_144\, and I was getting this error:

The JAVA_HOME environment variable is not defined correctly
This environment variable is needed to run this program
NB: JAVA_HOME should point to a JDK not a JRE

When I changed the JAVA_HOME to C:\Program Files\Java\jdk1.8.0_144\jre, the issue got fixed.
I am not sure how.

You want to look at the patch() function, and sneak in points for the start and end of the horizontal line:

x = 0:.1:2*pi;
y = sin(x)+rand(size(x))/2;

x2 = [0 x 2*pi];
y2 = [.1 y .1];
patch(x2, y2, [.8 .8 .1]);

If you only want the filled in area for a part of the data, you'll need to truncate the x and y vectors to only include the points you need.

The helpers are there mainly to help you display labels, form inputs, etc for the strongly typed properties of your model. By using the helpers and Visual Studio Intellisense, you can greatly reduce the number of typos that you could make when generating a web page.

With that said, you can continue to create your elements manually for both properties of your view model or items that you want to display that are not part of your view model.

At least on firefox, you can set a "title" attribute on the option tag:

<option value="" title="Tooltip">Some option</option>

Try This.

View:

@using (Html.BeginForm("Login", "Accounts", FormMethod.Post)) 
{
   <input type="text" name="IP" id="IP" />
   <input type="text" name="Name" id="Name" />

   <input type="submit" value="Login" />
}

Controller:

[HttpPost]
public ActionResult Login(string IP, string Name)
{
    string s1=IP;//
    string s2=Name;//
}

If you can use model class

[HttpPost]
public ActionResult Login(ModelClassName obj)
{
    string s1=obj.IP;//
    string s2=obj.Name;//
}

This probably isn't the most elegant way to do it, but it gets the job done.

Just replace '/Users/spencerlyon2/Desktop/test.csv' with the path to your file

str.startswith allows you to supply a tuple of strings to test for:

if link.lower().startswith(("js", "catalog", "script", "katalog")):

From the docs:

str.startswith(prefix[, start[, end]])

Return True if string starts with the prefix, otherwise return False. prefix can also be a tuple of prefixes to look for.

Below is a demonstration:

>>> "abcde".startswith(("xyz", "abc"))
True
>>> prefixes = ["xyz", "abc"]
>>> "abcde".startswith(tuple(prefixes)) # You must use a tuple though
True
>>>
