You actually want TestClass.instance_methods, unless you're interested in what TestClass itself can do.

class TestClass
  def method1
  end

  def method2
  end

  def method3
  end
end

TestClass.methods.grep(/method1/) # => []
TestClass.instance_methods.grep(/method1/) # => ["method1"]
TestClass.methods.grep(/new/) # => ["new"]

Or you can call methods (not instance_methods) on the object:

test_object = TestClass.new
test_object.methods.grep(/method1/) # => ["method1"]

You can use LINQ-to-DataSet with Enumerable.Any:

String author = "John Grisham";
bool contains = tbl.AsEnumerable().Any(row => author == row.Field<String>("Author"));

Another approach is to use DataTable.Select:

DataRow[] foundAuthors = tbl.Select("Author = '" + searchAuthor + "'");
if(foundAuthors.Length != 0)
{
    // do something...
}

Q: what if we do not know the columns Headers and we want to find if any cell value PEPSI exist in any rows'c columns? I can loop it all to find out but is there a better way? –

Yes, you can use this query:

DataColumn[] columns = tbl.Columns.Cast<DataColumn>().ToArray();
bool anyFieldContainsPepsi = tbl.AsEnumerable()
    .Any(row => columns.Any(col => row[col].ToString() == "PEPSI"));

setTimeout('$("#someDivId").hide()',1500);

As other answers have stated, there really just isn't a way that's any good. Base64 can be decoded. Bytecode can be decompiled. Python was initially just interpreted, and most interpreted languages try to speed up machine interpretation more than make it difficult for human interpretation.

Python was made to be readable and shareable, not obfuscated. The language decisions about how code has to be formatted were to promote readability across different authors.

Obfuscating python code just doesn't really mesh with the language. Re-evaluate your reasons for obfuscating the code.

The built-in matrix function has the nice option to enter data byrow. Combine that with an unlist on your source list will give you a matrix. We also need to specify the number of rows so it can break up the unlisted data. That is:

> matrix(unlist(a), byrow=TRUE, nrow=length(a) )
      [,1] [,2] [,3] [,4] [,5] [,6]
 [1,]    1    1    2    3    4    5
 [2,]    2    1    2    3    4    5
 [3,]    3    1    2    3    4    5
 [4,]    4    1    2    3    4    5
 [5,]    5    1    2    3    4    5
 [6,]    6    1    2    3    4    5
 [7,]    7    1    2    3    4    5
 [8,]    8    1    2    3    4    5
 [9,]    9    1    2    3    4    5
[10,]   10    1    2    3    4    5

A useful hack for me is to set the (selects) display to inline-flex. Cuts the arrow right out of my select button. Without all of the added code.

• For Fx only. -webkit appearance still needed for Chrome, etc...

As I wrote elsewhere

Packaging in Python is dire. The root cause is that the language ships without a package manager.

Fortunately, there is one package manager for Python, called Pip. Pip is inspired by Ruby's Gem, but lacks some features. Ironically, Pip itself is complicated to install. Installation on the popular 64-bit Windows demands building and installing two packages from source. This is a big ask for anyone new to programming.

So the right thing to do is to install pip. However if you can't be bothered, Christoph Gohlke provides binaries for popular Python packages for all Windows platforms http://www.lfd.uci.edu/~gohlke/pythonlibs/

In fact, building some Python packages requires a C compiler (eg. mingw32) and library headers for the dependencies. This can be a nightmare on Windows, so remember the name Christoph Gohlke.

Because when I use one or another I get a window prompt asking me to download the file for both of them.

This behavior depends on the browser and the file you are trying to serve. With inline, the browser will try to open the file within the browser.

For example, if you have a PDF file and Firefox/Adobe Reader, an inline disposition will open the PDF within Firefox, whereas attachment will force it to download.

If you're serving a .ZIP file, browsers won't be able to display it inline, so for inline and attachment dispositions, the file will be downloaded.

I think this should work, but i do not have the possibility to test it at the moment..

I did something quite simple. I did not want to change the windows 7 environment variable. So I directly edited the Cygwin.bat file.

@echo off
SETLOCAL
set HOME=C:\path\to\home
C:
chdir C:\apps\cygwin\bin
bash --login -i
ENDLOCAL

This just starts the local shell with this home directory; that is what I wanted. I am not going to remotely access this, so this worked for me.

On Windows, you could use this command.

taskkill /F /IM <processname>.exe 

To kill it forcefully, you may use;

Runtime.getRuntime().exec("taskkill /F /IM <processname>.exe")

This answer is simpler than my answer: https://stackoverflow.com/a/21718540/541862

Original answer:

# Create a backup of master branch
git branch backup_master

# Point master to '56e05fce' and
# make working directory the same with '56e05fce'
git reset --hard 56e05fce

# Point master back to 'backup_master' and
# leave working directory the same with '56e05fce'.
git reset --soft backup_master

# Now working directory is the same '56e05fce' and
# master points to the original revision. Then we create a commit.
git commit -a -m "Revert to 56e05fce"

# Delete unused branch
git branch -d backup_master

The two commands git reset --hard and git reset --soft are magic here. The first one changes the working directory, but it also changes head (the current branch) too. We fix the head by the second one.

I was getting the below error in my 32 bit application.

Error: Retrieving the COM class factory for component with CLSID {4911BB26-11EE-4182-B66C-64DF2FA6502D} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).

You can do via Page directive.

For example:

<%@ page language="java" contentType="application/json; charset=UTF-8"
    pageEncoding="UTF-8"%>

• contentType="mimeType [ ;charset=characterSet ]" | "text/html;charset=ISO-8859-1"

The MIME type and character encoding the JSP file uses for the response it sends to the client. You can use any MIME type or character set that are valid for the JSP container. The default MIME type is text/html, and the default character set is ISO-8859-1.

This seems to be the simplest regular expression of all that I found

(?:<TAG>)([\s\S]*)(?:<\/TAG>)

1. Exclude opening tag (?:<TAG>) from the matches
2. Include any whitespace or non-whitespace characters ([\s\S]*) in the matches
3. Exclude closing tag (?:<\/TAG>) from the matches

In my case of picking date from JXDatePicker (java calender) and getting it stored in database as SQL Date type, below works fine ..

java.sql.Date date = new java.sql.Date(pickedDate.getDate().getTime());

where pickedDate is object of JXDatePicker

Simple way to check that enter value is numeric is:

var checknumber = $('#textbox_id').val();

    if(jQuery.isNumeric(checknumber) == false){
        alert('Please enter numeric value');
        $('#special_price').focus();
        return;
    }

One other trick is to use ind2sub and sub2ind. In conjunction with numel and size, this can let you do stuff like the following, which creates an N-dimensional array, and then sets all the elements on the "diagonal" to be 1.

d = zeros( 3, 4, 5, 6 ); % Let's pretend this is a user input
nel = numel( d );
sz = size( d );
szargs = cell( 1, ndims( d ) ); % We'll use this with ind2sub in the loop
for ii=1:nel
    [ szargs{:} ] = ind2sub( sz, ii ); % Convert linear index back to subscripts
    if all( [szargs{2:end}] == szargs{1} ) % On the diagonal?
        d( ii ) = 1;
    end
end

You have to do a shift and mask (AND) operation. Let b be any byte and p be the index (>= 0) of the bit from which you want to take n bits (>= 1).

First you have to shift right b by p times:

x = b >> p;

Second you have to mask the result with n ones:

mask = (1 << n) - 1;
y = x & mask;

You can put everything in a macro:

#define TAKE_N_BITS_FROM(b, p, n) ((b) >> (p)) & ((1 << (n)) - 1)

• this is a merge of both ClandestineCoder & Binh WPO.

the problem with the script tag arrows is that they can have more than one variant

ex. (< = < = <) & ( > = > = >)

so instead of creating a pattern array with like a bazillion variant, imho a better solution would be

return preg_replace('/script.*?\/script/ius', '', $text)
       ? preg_replace('/script.*?\/script/ius', '', $text)
       : $text;

this will remove anything that look like script.../script regardless of the arrow code/variant and u can test it in here https://regex101.com/r/lK6vS8/1

inspired by @SteveLazaridis's answer, which would fail, here is a POSIX shell function - just copy and paste into a file named cpx in yout $PATH and make it executible (chmod a+x cpr). [Source is now maintained in my GitLab.

Dateformatter can make it to any string you want

Try this:

jQuery('#main').css('opacity', '0.6');

or

jQuery('#main').css({'filter':'alpha(opacity=60)', 'zoom':'1', 'opacity':'0.6'});

if you want to support IE7, IE8 and so on.

If you select the input by the id and then add the input[readonly="readonly"] tag in the css, something like:

 #inputID input[readonly="readonly"] {
     background-color: #000000;
 }

That will not work. You have to select a parent class or id an then the input. Something like:

 .parentClass, #parentID input[readonly="readonly"] {
     background-color: #000000;
 }

My 2 cents while waiting for new tickets at work :D

I think you are getting confused about what the a:active CSS selector does. This will only change the colour of your link when you click it (and only for the duration of the click i.e. how long your mouse button stays down). What you need to do is introduce a new class e.g. .selected into your CSS and when you select a link, update the selected menu item with new class e.g.

<div class="menuBar">
    <ul>
        <li class="selected"><a href="index.php">HOME</a></li>
        <li><a href="two.php">PORTFOLIO</a></li>
        ....
    </ul>
</div>

// specific CSS for your menu
div.menuBar li.selected a { color: #FF0000; } 
// more general CSS
li.selected a { color: #FF0000; }

You will need to update your template page to take in a selectedPage parameter.

... right now it happens only to the website I'm testing. I can't post it here because it's confidential.

Then I guess it is one of the sites which is incompatible with TLS1.2. The openssl as used in 12.04 does not use TLS1.2 on the client side while with 14.04 it uses TLS1.2 which might explain the difference. To work around try to explicitly use --secure-protocol=TLSv1. If this does not help check if you can access the site with openssl s_client -connect ... (probably not) and with openssl s_client -tls1 -no_tls1_1, -no_tls1_2 ....

Please note that it might be other causes, but this one is the most probable and without getting access to the site everything is just speculation anyway.

The assumed problem in detail: Usually clients use the most compatible handshake to access a server. This is the SSLv23 handshake which is compatible to older SSL versions but announces the best TLS version the client supports, so that the server can pick the best version. In this case wget would announce TLS1.2. But there are some broken servers which never assumed that one day there would be something like TLS1.2 and which refuse the handshake if the client announces support for this hot new version (from 2008!) instead of just responding with the best version the server supports. To access these broken servers the client has to lie and claim that it only supports TLS1.0 as the best version.

Is Ubuntu 14.04 or wget 1.15 not compatible with TLS 1.0 websites? Do I need to install/download any library/software to enable this connection?

The problem is the server, not the client. Most browsers work around these broken servers by retrying with a lower version. Most other applications fail permanently if the first connection attempt fails, i.e. they don't downgrade by itself and one has to enforce another version by some application specific settings.

You can just use the pipe on its own:

"string1|string2"

for example:

String s = "string1, string2, string3";
System.out.println(s.replaceAll("string1|string2", "blah"));

Output:

blah, blah, string3

The main reason to use parentheses is to limit the scope of the alternatives:

String s = "string1, string2, string3";
System.out.println(s.replaceAll("string(1|2)", "blah"));

has the same output. but if you just do this:

String s = "string1, string2, string3";
System.out.println(s.replaceAll("string1|2", "blah"));

you get:

blah, stringblah, string3

because you've said "string1" or "2".

If you don't want to capture that part of the expression use ?::

String s = "string1, string2, string3";
System.out.println(s.replaceAll("string(?:1|2)", "blah"));

This post has helped me a lot, and after a few iterations, this is what we use.

The idea is to post log messages and errors to HTML, for example if you need to debug JS and don't have access to the console.

You do need to change 'console.log' with 'logThis', as it is not recommended to change native functionality.

What you'll get:

• A plain and simple 'logThis' function that will display strings and objects along with current date and time for each line
• A dedicated window on top of everything else. (show it only when needed)
• Can be used inside '.catch' to see relevant errors from promises.
• No change of default console.log behavior
• Messages will appear in the console as well.

function logThis(message) {
  // if we pass an Error object, message.stack will have all the details, otherwise give us a string
  if (typeof message === 'object') {
    message = message.stack || objToString(message);
  }

  console.log(message);

  // create the message line with current time
  var today = new Date();
  var date = today.getFullYear() + '-' + (today.getMonth() + 1) + '-' + today.getDate();
  var time = today.getHours() + ':' + today.getMinutes() + ':' + today.getSeconds();
  var dateTime = date + ' ' + time + ' ';

  //insert line
  document.getElementById('logger').insertAdjacentHTML('afterbegin', dateTime + message + '<br>');
}

function objToString(obj) {
  var str = 'Object: ';
  for (var p in obj) {
    if (obj.hasOwnProperty(p)) {
      str += p + '::' + obj[p] + ',\n';
    }
  }
  return str;
}

const object1 = {
  a: 'somestring',
  b: 42,
  c: false
};

logThis(object1)
logThis('And all the roads we have to walk are winding, And all the lights that lead us there are blinding')

#logWindow {
  overflow: auto;
  position: absolute;

  height: 90%;
  top: 5%;

}

Thanks this answer too, JSON.stringify() didn't work for this.

If you are using python2.7 or above you can use the ability of assertRaises to be use as a context manager and do:

with self.assertRaises(TypeError):
    self.testListNone[:1]

If you are using python2.6 another way beside the one given until now is to use unittest2 which is a back port of unittest new feature to python2.6, and you can make it work using the code above.

N.B: I'm a big fan of the new feature (SkipTest, test discovery ...) of unittest so I intend to use unittest2 as much as I can. I advise to do the same because there is a lot more than what unittest come with in python2.6 <.

Say I want to import data into a component from src/mylib.js:

var test = {
  foo () { console.log('foo') },
  bar () { console.log('bar') },
  baz () { console.log('baz') }
}

export default test

In my .Vue file I simply imported test from src/mylib.js:

<script> 
  import test from '@/mylib'

  console.log(test.foo())
  ...
</script>

ALTER IGNORE TABLE mytbl ADD UNIQUE (columnName);

For MySQL 5.7.4 or later:

ALTER TABLE mytbl ADD UNIQUE (columnName);

As of MySQL 5.7.4, the IGNORE clause for ALTER TABLE is removed and its use produces an error.

So, make sure to remove duplicate entries first as IGNORE keyword is no longer supported.

Reference

Others have given you the answer about appendChild.

Calling document.write() on a page that is not open (e.g. has finished loading) first calls document.open() which clears the entire content of the document (including the script calling document.write), so it's rarely a good idea to do that.

.NET 4.5 is not a side-by-side version, it replaces the assemblies for 4.0. Much like .NET 3.0, 3.5 and 3.5SP1 replaced the assemblies for 2.0. And added some new ones. The CLR version is still 4.0.30319. You only care about the reference assemblies, they are in c:\program files\reference assemblies.

One more thing to watch out for is if the second value was another Integer object instead of a literal '0', the '==' operator compares the object pointers and will not auto-unbox.

ie:

Integer a = new Integer(0);   
Integer b = new Integer(0);   
int c = 0;

boolean isSame_EqOperator = (a==b); //false!
boolean isSame_EqMethod = (a.equals(b)); //true
boolean isSame_EqAutoUnbox = ((a==c) && (a.equals(c)); //also true, because of auto-unbox

//Note: for initializing a and b, the Integer constructor 
// is called explicitly to avoid integer object caching 
// for the purpose of the example.
// Calling it explicitly ensures each integer is created 
// as a separate object as intended.

Just wanted to summarize all the correct answers above in short. Because I had to spend lot of time to figure out which answer resolves the issue and what's going on behind the scenes.

There seems to be two problems of fieldset with bootstrap:

1. The bootstrap sets the width to the legend as 100%. That is why it overlays the top border of the fieldset.
2. There's a bottom border for the legend.

So, all we need to fix this is set the legend width to auto as follows:

legend.scheduler-border {
   width: auto; // fixes the problem 1
   border-bottom: none; // fixes the problem 2
}

Well 'typescriptlang' seems to be recommending using interface over types where ever possible. Interface vs Type Alias

There is another solution I've been using. Just create a string property and use it for json. This property wil return date properly formatted.

class JSonModel {
    ...

    [JsonIgnore]
    public DateTime MyDate { get; set; }

    [JsonProperty("date")]
    public string CustomDate {
        get { return MyDate.ToString("ddMMyyyy"); }
        // set { MyDate = DateTime.Parse(value); }
        set { MyDate = DateTime.ParseExact(value, "ddMMyyyy", null); }
    }

    ...
}

This way you don't have to create extra classes. Also, it allows you to create diferent data formats. e.g, you can easily create another Property for Hour using the same DateTime.

The whole point of using a mapping technology like Jackson is that you can use Objects (you don't have to parse the JSON yourself).

Define a Java class that resembles the JSON you will be expecting.

e.g. this JSON:

{
"foo" : ["abc","one","two","three"],
"bar" : "true",
"baz" : "1"
}

could be mapped to this class:

public class Fizzle{
    private List<String> foo;
    private boolean bar;
    private int baz;
    // getters and setters omitted
}

Now if you have a Controller method like this:

@RequestMapping("somepath")
@ResponseBody
public Fozzle doSomeThing(@RequestBody Fizzle input){
    return new Fozzle(input);
}

and you pass in the JSON from above, Jackson will automatically create a Fizzle object for you, and it will serialize a JSON view of the returned Object out to the response with mime type application/json.

For a full working example see this previous answer of mine.

If anyone wants to build a viewPager with thumbnails as indicators, using this library could be an option: ThumbIndicator for viewPager that works also with image links as resources.

When using lombok on a fresh installation of Eclipse or STS, you have to:

1. Install the lombok jar which you can get at https://projectlombok.org/download. Run the jar (as Administrator if using windows) and specify the path to your Eclipse/STS installation.

2. Restart your IDE (Eclipse or STS)

3. Give some time for eclipse to generate the class files for lombok (Might take a up to 4 mins in some cases)

I use the file *nix command to convert a unknown charset file in a utf-8 file

# -*- encoding: utf-8 -*-

# converting a unknown formatting file in utf-8

import codecs
import commands

file_location = "jumper.sub"
file_encoding = commands.getoutput('file -b --mime-encoding %s' % file_location)

file_stream = codecs.open(file_location, 'r', file_encoding)
file_output = codecs.open(file_location+"b", 'w', 'utf-8')

for l in file_stream:
    file_output.write(l)

file_stream.close()
file_output.close()

Binary to Decimal

int(binaryString, 2)

Decimal to Binary

If you're just doing some quick and dirty temporary work, you can also skip typing out an explicit CREATE TABLE statement and just make the temp table with a SELECT...INTO and include an Identity field in the select list.

select IDENTITY(int, 1, 1) as ROW_ID,
       Name
into #tmp
from (select 'Bob' as Name union all
      select 'Susan' as Name union all
      select 'Alice' as Name) some_data

select *
from #tmp

This is how node-validator does it:

/^(?:[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+\.)*[\w\!\#\$\%\&\'\*\+\-\/\=\?\^\`\{\|\}\~]+@(?:(?:(?:[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!\.)){0,61}[a-zA-Z0-9]?\.)+[a-zA-Z0-9](?:[a-zA-Z0-9\-](?!$)){0,61}[a-zA-Z0-9]?)|(?:\[(?:(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\.){3}(?:[01]?\d{1,2}|2[0-4]\d|25[0-5])\]))$/

This problem is due to:

• an old version of pip (6.1.1) being installed for Python 2.7
• multiple copies of Python 2.7 installed on the Trusty Beta image
• a different location for Python 2.7 being used for sudo

It's all a bit complicated and better explained here https://github.com/travis-ci/travis-ci/issues/4989.

My solution was to install with user travis instead of sudo:

- pip2.7 install --upgrade --user travis pip setuptools wheel virtualenv

Install List::MoreUtils from CPAN

Then in your code:

use strict;
use warnings;
use List::MoreUtils qw(uniq);

my @dup_list = qw(1 1 1 2 3 4 4);

my @uniq_list = uniq(@dup_list);

map() doesn't return a list, it returns a map object.

You need to call list(map) if you want it to be a list again.

Even better,

from itertools import imap
payIntList = list(imap(int, payList))

Won't take up a bunch of memory creating an intermediate object, it will just pass the ints out as it creates them.

Also, you can do if choice.lower() == 'n': so you don't have to do it twice.

Python supports +=: you can do payIntList[i] += 1000 and numElements += 1 if you want.

If you really want to be tricky:

from itertools import count
for numElements in count(1):
    payList.append(raw_input("Enter the pay amount: "))
    if raw_input("Do you wish to continue(y/n)?").lower() == 'n':
         break

and / or

for payInt in payIntList:
    payInt += 1000
    print payInt

Also, four spaces is the standard indent amount in Python.

This is how I've recently fixed the error

    @app.route('/')
    def home():
        docs = []
        for doc in db.person.find():
            doc.pop('_id') 
            docs.append(doc)
        return jsonify(docs)

@anothershrubery answer worked for me. I've made an enhancement using StringEntensions Class so I can easily convert any string at all in my program.

Method:

public static class StringExtensions
{
    public static string ToUTF8(this string text)
    {
        return Encoding.UTF8.GetString(Encoding.Default.GetBytes(text));
    }
}

Usage:

string myString = "Acción";
string strConverted = myString.ToUTF8();

Or simply:

string strConverted = "Acción".ToUTF8();

1. git reset --hard CommitId
2. git push -f origin master

1st command will rest your head to commitid and 2nd command will delete all commit after that commit id on master branch.

Note: Don't forget to add -f in push otherwise it will be rejected.

just parse as an array:

Review[] reviews = new Gson().fromJson(jsonString, Review[].class);

then if you need you can also create a list in this way:

List<Review> asList = Arrays.asList(reviews);

P.S. your json string should be look like this:

[
    {
        "reviewerID": "A2SUAM1J3GNN3B1",
        "asin": "0000013714",
        "reviewerName": "J. McDonald",
        "helpful": [2, 3],
        "reviewText": "I bought this for my husband who plays the piano.",
        "overall": 5.0,
        "summary": "Heavenly Highway Hymns",
        "unixReviewTime": 1252800000,
        "reviewTime": "09 13, 2009"
    },
    {
        "reviewerID": "A2SUAM1J3GNN3B2",
        "asin": "0000013714",
        "reviewerName": "J. McDonald",

        "reviewTime": "09 13, 2009"
    },

    [...]
]

select username,
       account_status 
  from dba_users 
 where lock_date is not null;

This will actually give you the list of locked users.

Alternatively you can install GNU date like so:

1. install Homebrew: https://brew.sh/
2. brew install coreutils
3. add to your bash_profile: alias date="/usr/local/bin/gdate"
4. date +%s 1547838127

Comments saying Mac has to be "different" simply reveal the commenter is ignorant of the history of UNIX. macOS is based on BSD UNIX, which is way older than Linux. Linux essentially was a copy of other UNIX systems, and Linux decided to be "different" by adopting GNU tools instead of BSD tools. GNU tools are more user friendly, but they're not usually found on any *BSD system (just the way it is).

Really, if you spend most of your time in Linux, but have a Mac desktop, you probably want to make the Mac work like Linux. There's no sense in trying to remember two different sets of options, or scripting for the mac's BSD version of Bash, unless you are writing a utility that you want to run on both BSD and GNU/Linux shells.

Easiest way is defining track tint, and setting tint mode to src_over to remove 30% transparency.

android:trackTint="@drawable/toggle_style"
android:trackTintMode="src_over"

toggle_style.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/informationDefault"
        android:state_checked="true"
        />
    <item android:color="@color/textDisabled" android:state_checked="false"/>
</selector>

It depends on the server configuration or the relevant directives session.gc_maxlifetime in php.ini.

Typically the default is 24 minutes (1440 seconds), but your webhost may have altered the default to something else.

For SQL Server 2012:

SELECT name, modify_date, create_date, type
FROM sys.procedures
WHERE name like '%XXX%' 
ORDER BY modify_date desc

From the Maven docs, sounds like it's just a difference in which repository you install the package into:

• install - install the package into the local repository, for use as a dependency in other projects locally
• deploy - done in an integration or release environment, copies the final package to the remote repository for sharing with other developers and projects.

Maybe there is some confusion in that "install" to the CI server installs it to it's local repository, which then you as a user are sharing?

Add the following line on the top of your file

require 'json'

Then you can use:

car = {:make => "bmw", :year => "2003"}
car.to_json

Alternatively, you can use:

JSON.generate({:make => "bmw", :year => "2003"})

If you want to write portable C++ code, then I'd suggest using cin.get().

system("PAUSE") works on Windows, since it requires the execution of a console command named "PAUSE". But I'm not sure that other operating systems like Linux or other Unix derivatives support that. So that tends to be non-portable.

Since C++ already offers cin.get(), I see no compelling reason to use C getch().

The best and easy way for image resize using Java Swing is:

jLabel.setIcon(new ImageIcon(new javax.swing.ImageIcon(getClass().getResource("/res/image.png")).getImage().getScaledInstance(200, 50, Image.SCALE_SMOOTH)));

For better display, identify the actual height & width of image and resize based on width/height percentage

The first method is right.

The second method kills kittens if you attempt to do anything with x after the fact other than Object methods.

In one-to-one relation one end must be principal and second end must be dependent. Principal end is the one which will be inserted first and which can exist without the dependent one. Dependent end is the one which must be inserted after the principal because it has foreign key to the principal.

In case of entity framework FK in dependent must also be its PK so in your case you should use:

public class Boo
{
    [Key, ForeignKey("Foo")]
    public string BooId{get;set;}
    public Foo Foo{get;set;}
}

Or fluent mapping

modelBuilder.Entity<Foo>()
            .HasOptional(f => f.Boo)
            .WithRequired(s => s.Foo);

     int average = 0;

     for (int i = 0; i < size; i++)

You can use String arrays to add jComboBox items

String [] items = { "First item", "Second item", "Third item", "Fourth item" };

JComboBox comboOne = new JComboBox (items);

This works in my case for getting table name and column name in the corresponding table for indexed fields.

SELECT TABLE_NAME , COLUMN_NAME, COMMENT 
FROM information_schema.statistics
WHERE table_schema = 'database_name';

Easy way to do:

NSInteger value = x;
NSString *string = [@(value) stringValue];

Here the @(value) converts the given NSInteger to an NSNumber object for which you can call the required function, stringValue.

You could use a regular expression replace:

str = str.replace(/ +(?= )/g,'');

Credit: The above regex was taken from Regex to replace multiple spaces with a single space

A collector can be used for this.

• For two categories, use Collectors.partitioningBy() factory.

This will create a Map from Boolean to List, and put items in one or the other list based on a Predicate.

Note: Since the stream needs to be consumed whole, this can't work on infinite streams. And because the stream is consumed anyway, this method simply puts them in Lists instead of making a new stream-with-memory. You can always stream those lists if you require streams as output.

Also, no need for the iterator, not even in the heads-only example you provided.

• Binary splitting looks like this:

Random r = new Random();

Map<Boolean, List<String>> groups = stream
    .collect(Collectors.partitioningBy(x -> r.nextBoolean()));

System.out.println(groups.get(false).size());
System.out.println(groups.get(true).size());

• For more categories, use a Collectors.groupingBy() factory.

Map<Object, List<String>> groups = stream
    .collect(Collectors.groupingBy(x -> r.nextInt(3)));
System.out.println(groups.get(0).size());
System.out.println(groups.get(1).size());
System.out.println(groups.get(2).size());

In case the streams are not Stream, but one of the primitive streams like IntStream, then this .collect(Collectors) method is not available. You'll have to do it the manual way without a collector factory. It's implementation looks like this:

[Example 2.0 since 2020-04-16]

    IntStream    intStream = IntStream.iterate(0, i -> i + 1).limit(100000).parallel();
    IntPredicate predicate = ignored -> r.nextBoolean();

    Map<Boolean, List<Integer>> groups = intStream.collect(
            () -> Map.of(false, new ArrayList<>(100000),
                         true , new ArrayList<>(100000)),
            (map, value) -> map.get(predicate.test(value)).add(value),
            (map1, map2) -> {
                map1.get(false).addAll(map2.get(false));
                map1.get(true ).addAll(map2.get(true ));
            });

In this example I initialize the ArrayLists with the full size of the initial collection (if this is known at all). This prevents resize events even in the worst-case scenario, but can potentially gobble up 2*N*T space (N = initial number of elements, T = number of threads). To trade-off space for speed, you can leave it out or use your best educated guess, like the expected highest number of elements in one partition (typically just over N/2 for a balanced split).

I hope I don't offend anyone by using a Java 9 method. For the Java 8 version, look at the edit history.

My guess is your PHP installation wasn't compiled with MySQL support.

Check your configure command (php -i | grep mysql). You should see something like '--with-mysql=shared,/usr'.

You can check for complete instructions at http://php.net/manual/en/mysql.installation.php. Although, I would rather go with the solution proposed by @wanovak.

Still, I think you need MySQL support in order to use PDO.

To count a value in a two dimensional array, here is the useful snippet to process and get count of a particular value-

    <?php
    
    $list = [
      ['id' => 1, 'userId' => 5],
      ['id' => 2, 'userId' => 5],
      ['id' => 3, 'userId' => 6],
    ];

    $userId = 5;
    
    echo array_count_values(array_column($list, 'userId'))[$userId]; // outputs: 2
    

tl;dr

I was looking for a one-liner like:

Ask and ye shall receive. Convert from terrible legacy class Date to its modern replacement, Instant.

myJavaUtilDate.toInstant().toString()

2020-05-05T19:46:12.912Z

java.time

In Java 8 and later we have the new java.time package built in (Tutorial). Inspired by Joda-Time, defined by JSR 310, and extended by the ThreeTen-Extra project.

The best solution is to sort your date-time objects rather than strings. But if you must work in strings, read on.

An Instant represents a moment on the timeline, basically in UTC (see class doc for precise details). The toString implementation uses the DateTimeFormatter.ISO_INSTANT format by default. This format includes zero, three, six or nine digits digits as needed to display fraction of a second up to nanosecond precision.

String output = Instant.now().toString(); // Example: '2015-12-03T10:15:30.120Z'

If you must interoperate with the old Date class, convert to/from java.time via new methods added to the old classes. Example: Date::toInstant.

myJavaUtilDate.toInstant().toString()

You may want to use an alternate formatter if you need a consistent number of digits in the fractional second or if you need no fractional second.

Another route if you want to truncate fractions of a second is to use ZonedDateTime instead of Instant, calling its method to change the fraction to zero.

Note that we must specify a time zone for ZonedDateTime (thus the name). In our case that means UTC. The subclass of ZoneID, ZoneOffset, holds a convenient constant for UTC. If we omit the time zone, the JVM’s current default time zone is implicitly applied.

String output = ZonedDateTime.now( ZoneOffset.UTC ).withNano( 0 ).toString();  // Example: 2015-08-27T19:28:58Z

About java.time

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

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

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

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes. Hibernate 5 & JPA 2.2 support java.time.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, Java SE 11, and later - Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Most of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

Joda-Time

UPDATE: The Joda -Time project is now in maintenance mode, with the team advising migration to the java.time classes.

I was looking for a one-liner

Easy if using the Joda-Time 2.3 library. ISO 8601 is the default formatting.

Time Zone

In the code example below, note that I am specifying a time zone rather than depending on the default time zone. In this case, I'm specifying UTC per your question. The Z on the end, spoken as "Zulu", means no time zone offset from UTC.

Example Code

// import org.joda.time.*;

String output = new DateTime( DateTimeZone.UTC );

Output…

2013-12-12T18:29:50.588Z

Dim evaluator As New Thread(Sub() Me.testthread(goodList, 1))

For any person using @variable in concat_ws function to get concatenated values, don't forget to reinitialize it with empty value. Otherwise it can use old value for same session.

Set @Ids = '';

select 
  @Ids := concat_ws(',',@Ids,tbl.Id),
  tbl.Col1,
  ...
from mytable tbl;

If you set the border-collapse style to collapse on the parent table you should be able to style the tr: (styles are inline for demo)

  <tr style="border:2px solid #f00;">
    <td>Border</td>
  </tr>
  <tr>
    <td>No Border</td>
  </tr>
</table>

Output:

exit code 139 (people say this means memory fragmentation)

No, it means that your program died with signal 11 (SIGSEGV on Linux and most other UNIXes), also known as segmentation fault.

Could anybody tell me why the run fails but debug doesn't?

Your program exhibits undefined behavior, and can do anything (that includes appearing to work correctly sometimes).

Your first step should be running this program under Valgrind, and fixing all errors it reports.

If after doing the above, the program still crashes, then you should let it dump core (ulimit -c unlimited; ./a.out) and then analyze that core dump with GDB: gdb ./a.out core; then use where command.

I think You are copying the .exe to different location. This might be the problem I guess. When you copy the exe, you are not copying its dependencies.

So, what you can do is, put all dependent dlls in GAC so that any .net exe can access it

Else, do not copy the exe to new location. Just create a environment variable and call the exe in your c#. Since the path is defined in environment variables, the exe is can be accessed by your c# program.

Update:

previously I had some kind of same issue in my c#.net 3.5 project in which I was trying to run a .exe file from c#.net code and that exe was nothing but the another project exe(where i added few supporting dlls for my functionality) and those dlls methods I was using in my exe application. At last I resolved this by creating that application as a separate project to the same solution and i added that project output to my deployment project. According to this scenario I answered, If its not what he wants then I am extremely sorry.

The python manual provides the following:

import termios, fcntl, sys, os
fd = sys.stdin.fileno()

oldterm = termios.tcgetattr(fd)
newattr = termios.tcgetattr(fd)
newattr[3] = newattr[3] & ~termios.ICANON & ~termios.ECHO
termios.tcsetattr(fd, termios.TCSANOW, newattr)

oldflags = fcntl.fcntl(fd, fcntl.F_GETFL)
fcntl.fcntl(fd, fcntl.F_SETFL, oldflags | os.O_NONBLOCK)

try:
    while 1:
        try:
            c = sys.stdin.read(1)
            print "Got character", repr(c)
        except IOError: pass
finally:
    termios.tcsetattr(fd, termios.TCSAFLUSH, oldterm)
    fcntl.fcntl(fd, fcntl.F_SETFL, oldflags)

which can be rolled into your use case.

I faced similar issue with similar logs. I was using JDK 1.6 with apache tomcat 7. Setting java_home to 1.7 resolved the issue.

I hope this helps someone.

What I have done here is that I have returned a promise from the justTesting function. You can then get the result when the function is resolved.

// new answer

function justTesting() {
  return new Promise((resolve, reject) => {
    if (true) {
      return resolve("testing");
    } else {
      return reject("promise failed");
   }
 });
}

justTesting()
  .then(res => {
     let test = res;
     // do something with the output :)
  })
  .catch(err => {
    console.log(err);
  });

Hope this helps!

// old answer

function justTesting() {
  return promise.then(function(output) {
    return output + 1;
  });
}

justTesting().then((res) => {
     var test = res;
    // do something with the output :)
    }

You're most likely using this on a local file over the file:// URI scheme, which cannot have cookies set. Put it on a local server so you can use http://localhost.

I was having the same problem with android tabs when trying to place them on the bottom of the screen.

Sweet and simple:

1. Open the repository
2. Navigate to settings
3. Scroll to the bottom of the page
4. Click on delete
5. Confirm names of the Repository to delete
6. Click on delete

Have a button on list and let it onclick feature in xml like to get postion first

public void OnClickButton(View V){
  final int postion = listView.getPositionForView(V);
    System.out.println("postion selected is : "+postion);
Delete(postion);

}
public void Delete(int position){
    if (adapter.getCount() > 0) {

        //Log.d("largest no is",""+largestitemno);
        //deleting the latest added by subtracting one 1 
        comment = (GenrricStoring) adapter.getItem(position);
        //Log.d("Deleting item is: ",""+comment);
        dbconnection.deleteComment(comment);
        List<GenrricStoring> values = dbconnection.getAllComments();
        //updating the content on the screen
        this.adapter = new UserItemAdapter(this, android.R.layout.simple_list_item_1, values);
        listView.setAdapter(adapter);
    }
    else
    {
        int duration = Toast.LENGTH_SHORT;
        //for showing nothing is left in the list
        Toast toast = Toast.makeText(getApplicationContext(),"Db is empty", duration);
        toast.setGravity(Gravity.CENTER, 0, 0);

        toast.show();
    }

}

Give this a try

$indo=$_GET['id'];
$result = mysql_query("SELECT * FROM student WHERE IDNO='$indo'");

I think this works..

I was able to use

return View::make('myviewfolder.myview', compact('view1','view2','view3'));

I don't know if it's because I am using PHP 5.5 it works great :)

just put height="400px" into image attribute like

<img class="d-block w-100" src="../assets/img/natural-backdrop.jpg" height="400px" alt="First slide">

Best solution for this is to download and install VCforPython2.7 from https://www.microsoft.com/en-us/download/details.aspx?id=44266

Then try pip install numpy

Although GitHub removed the private messaging feature, there's still an alternative.

GitHub host git repositories. If the user you're willing to communicate with has ever committed some code, there are good chances you may reach your goal. Indeed, within each commit is stored some information about the author of the change or the one who accepted it.

Provided you're really dying to exchange with user user_test

• Display the public activity page of the user: https://github.com/user_test?tab=activity
• Search for an event stating "user_test pushed to [branch] at [repository]". There are usually good chances, they may have pushed one of his own commits. Ensure this is the case by clicking on the "View comparison..." link and make sure the user is listed as one of the committers.
• Clone on your local machine the repository they pushed to: git clone https://github.com/..../repository.git
• Checkout the branch they pushed to: git checkout [branch]
• Display the latest commits: git log -50

As a committer/author, an email should be displayed along with the commit data.

Note: Every warning related to unsolicited email should apply there. Do not spam.

As said by jensgram, IE6 does not support attribute selector. You could add a class="disabled" to select the disabled inputs so that this can work in IE6.

Here I am using iTextSharp dll for generating PDF file. I want to open PDF file instead of downloading it. So I am using below code which is working fine for me. Now pdf file is opening in browser ,now dowloading

        Document pdfDoc = new Document(PageSize.A4, 25, 10, 25, 10);
        PdfWriter pdfWriter = PdfWriter.GetInstance(pdfDoc, Response.OutputStream);
        pdfDoc.Open();
        Paragraph Text = new Paragraph("Hi , This is Test Content");
        pdfDoc.Add(Text);
        pdfWriter.CloseStream = false;
        pdfDoc.Close();
        Response.Buffer = true;
        Response.ContentType = "application/pdf";
        Response.Cache.SetCacheability(HttpCacheability.NoCache);
        Response.End();

If you want to download file, add below line, after this Response.ContentType = "application/pdf";

Response.AddHeader("content-disposition", "attachment;filename=Example.pdf");   

You can use some function to initialize struct as follows,

typedef struct
{
    int flag;
} MyStruct;

MyStruct GetMyStruct(int value)
{
    MyStruct My = {0};
    My.flag = value;
    return My;
}

void main (void)
{
    MyStruct temp;
    temp = GetMyStruct(3);
    printf("%d\n", temp.flag);
}

EDIT:

typedef struct
{
    int flag;
} MyStruct;

MyStruct MyData[20];

MyStruct GetMyStruct(int value)
{
    MyStruct My = {0};
    My.flag = value;
    return My;
}

void main (void)
{
    int i;
    for (i = 0; i < 20; i ++)
        MyData[i] = GetMyStruct(3);

    for (i = 0; i < 20; i ++)
        printf("%d\n", MyData[i].flag);
}

I encountered same issue during the load test, the reason is because of JVM is unable to create a new Java thread further. Below is the JVM source code

if (native_thread->osthread() == NULL) {    
// No one should hold a reference to the 'native_thread'.    
    delete native_thread;   
if (JvmtiExport::should_post_resource_exhausted()) {      
    JvmtiExport::post_resource_exhausted(        
        JVMTI_RESOURCE_EXHAUSTED_OOM_ERROR | 
        JVMTI_RESOURCE_EXHAUSTED_THREADS, 
        "unable to create new native thread");    
    } THROW_MSG(vmSymbols::java_lang_OutOfMemoryError(), "unable to create new native thread");  
} Thread::start(native_thread);`

Root cause : JVM throws this exception when JVMTI_RESOURCE_EXHAUSTED_OOM_ERROR (resources exhausted (means memory exhausted) ) or JVMTI_RESOURCE_EXHAUSTED_THREADS (Threads exhausted).

In my case Jboss is creating too many threads , to serve the request, but all the threads are blocked . Because of this, JVM is exhausted with threads as well with memory (each thread holds memory , which is not released , because each thread is blocked).

Analyzed the java thread dumps observed nearly 61K threads are blocked by one of our method, which is causing this issue . Below is the portion of Thread dump

"SimpleAsyncTaskExecutor-16562" #38070 prio=5 os_prio=0 tid=0x00007f9985440000 nid=0x2ca6 waiting for monitor entry [0x00007f9d58c2d000]
   java.lang.Thread.State: BLOCKED (on object monitor)

If we need to show different type of view in list-view then its good to use getViewTypeCount() and getItemViewType() in adapter instead of toggling a view VIEW.GONE and VIEW.VISIBLE can be very expensive task inside getView() which will affect the list scroll.

Please check this one for use of getViewTypeCount() and getItemViewType() in Adapter.

the _timestamp didn't work out for me,

this query does work for me:

(as in mconlin's answer)

{
  "query": {
    "match_all": {}
  },
  "size": "1",
  "sort": [
    {
      "@timestamp": {
        "order": "desc"
      }
    }
  ]
}

Could be trivial but the _timestamp answer didn't gave an error but not a good result either...

Hope to help someone...

[NSTimer scheduledTimerWithTimeInterval:.06 target:self selector:@selector(goToSecondButton:) userInfo:nil repeats:NO];

Is the best one to use. Using sleep(15); will cause the user unable to perform any other actions. With the following function, you would replace goToSecondButton with the appropriate selector or command, which can also be from the frameworks.

Looks like your style has been sanitized, to bypass it try using bypassSecurityTrustStyle method from DomSanitizer.

import { Component, OnInit, Input } from '@angular/core';_x000D_
import { DomSanitizer, SafeStyle } from '@angular/platform-browser';_x000D_

Use .loc for label based indexing:

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

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

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

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

If I understood your question, here is the solution :

    $.ajaxSetup({ cache: true});

and for specific calls

 $.ajax({
        url: ...,
        type: "GET",
        cache: false,           
        ...
    });

If you want opposite (cache for specific calls) you can set false at the beginning and true for specific calls.

There is an easier way if you are using phpMyAdmin as your MySQL front end:

1. Create a database with the default settings.
2. Select the database.
3. Click "Import" at the top of the screen.
4. Select "CSV" under "Format".
5. Choose the options appropriate to your CSV file, open the CSV file in a text editor and reference it to get the "appropriate" options.

If you have problems, no problem, simply drop the database and try again.

You need to call the AddAddress method once for every recipient. Like so:

$mail->AddAddress('[email protected]', 'Person One');
$mail->AddAddress('[email protected]', 'Person Two');
// ..

Better yet, add them as Carbon Copy recipients.

$mail->AddCC('[email protected]', 'Person One');
$mail->AddCC('[email protected]', 'Person Two');
// ..

To make things easy, you should loop through an array to do this.

$recipients = array(
   '[email protected]' => 'Person One',
   '[email protected]' => 'Person Two',
   // ..
);
foreach($recipients as $email => $name)
{
   $mail->AddCC($email, $name);
}

If you are using jersey 2.x then you need different configuration in web.xml as servlet class is change in it. you can update your web.xml with following configuration.

    <servlet>
    <servlet-name>myrest</servlet-name>
    <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>    
    <init-param>
      <param-name>jersey.config.server.provider.packages</param-name>
      <param-value>your.package.path</param-value>
    </init-param>
    <init-param>
     <param-name>unit:WidgetPU</param-name>
     <param-value>persistence/widget</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>myrest</servlet-name>
    <url-pattern>/rest/*</url-pattern>
  </servlet-mapping>

Note that solutions with timedelta.total_seconds() work on python-2.7+. Use calendar.timegm(future.utctimetuple()) for lower versions of Python.

I think you can find your answer here : Is an anchor tag without the href attribute safe?

Also if you want to no link operation with href , you can use it like :

<a href="javascript:void(0);">something</a>

this is an out of topic answer, but, for those who are interested, it maybe valuable.

As in @John Kugelman's answer, % is related to job specification. how to efficiently find that? use less's &pattern command, seems man use less pager (not that sure), in man bash type &% then type Enter will only show lines that containing '%', to reshow all, type &. then Enter.

Yes, Daniel is correct, but to expand upon his answer, your primary app component would need to have a navbar component within it. That way, when you render the primary app (any page under the '/' path), it would also display the navbar. I am guessing that you wouldn't want your login page to display the navbar, so that shouldn't be a nested component, and should instead be by itself. So your routes would end up looking something like this:

<Router>
  <Route path="/" component={App}>
    <Route path="page1" component={Page1} />
    <Route path="page2" component={Page2} />
  </Route>
  <Route path="/login" component={Login} />
</Router>

And the other components would look something like this:

var NavBar = React.createClass({
  render() {
    return (
      <div>
        <ul>
          <a onClick={() => history.push('page1') }>Page 1</a>
          <a onClick={() => history.push('page2') }>Page 2</a>
        </ul>
      </div>
    )
  }
});

var App = React.createClass({
  render() {
    return (
      <div>
        <NavBar />
        <div>Other Content</div>
        {this.props.children}
      </div>
    )
  }
});

The proper way to do it is using the ng-options directive. The HTML would look like this.

<select ng-model="selectedTestAccount" 
        ng-options="item.Id as item.Name for item in testAccounts">
    <option value="">Select Account</option>
</select>

JavaScript:

angular.module('test', []).controller('DemoCtrl', function ($scope, $http) {
    $scope.selectedTestAccount = null;
    $scope.testAccounts = [];

    $http({
            method: 'GET',
            url: '/Admin/GetTestAccounts',
            data: { applicationId: 3 }
        }).success(function (result) {
        $scope.testAccounts = result;
    });
});

You'll also need to ensure angular is run on your html and that your module is loaded.

<html ng-app="test">
    <body ng-controller="DemoCtrl">
    ....
    </body>
</html>

There is a built-in method to get the bounding rectangle: Element.getBoundingClientRect.

The result is the smallest rectangle which contains the entire element, with the read-only left, top, right, bottom, x, y, width, and height properties.

See the example below:

let innerBox = document.getElementById("myDiv").getBoundingClientRect().height;_x000D_
document.getElementById("data_box").innerHTML = "height: " + innerBox;

body {_x000D_
  margin: 0;_x000D_
}_x000D_
_x000D_
.relative {_x000D_
  width: 220px;_x000D_
  height: 180px;_x000D_
  position: relative;_x000D_
  background-color: purple;_x000D_
}_x000D_
_x000D_
.absolute {_x000D_
  position: absolute;_x000D_
  top: 30px;_x000D_
  left: 20px;_x000D_
  background-color: orange;_x000D_
  padding: 30px;_x000D_
  overflow: hidden;_x000D_
}_x000D_
_x000D_
#myDiv {_x000D_
  margin: 20px;_x000D_
  padding: 10px;_x000D_
  color: red;_x000D_
  font-weight: bold;_x000D_
  background-color: yellow;_x000D_
}_x000D_
_x000D_
#data_box {_x000D_
  font: 30px arial, sans-serif;_x000D_
}

Get height of <mark>myDiv</mark> in px dimension:_x000D_

This assumes a few things, that you know what the output file name will be and that your data comes as a string. I'm sure you can modify the following to meet your needs:

// Needed Imports
import java.io.ByteArrayInputStream;
import sun.misc.BASE64Decoder;


def sourceData = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAPAAAADwCAYAAAA+VemSAAAgAEl...==';

// tokenize the data
def parts = sourceData.tokenize(",");
def imageString = parts[1];

// create a buffered image
BufferedImage image = null;
byte[] imageByte;

BASE64Decoder decoder = new BASE64Decoder();
imageByte = decoder.decodeBuffer(imageString);
ByteArrayInputStream bis = new ByteArrayInputStream(imageByte);
image = ImageIO.read(bis);
bis.close();

// write the image to a file
File outputfile = new File("image.png");
ImageIO.write(image, "png", outputfile);

Please note, this is just an example of what parts are involved. I haven't optimized this code at all and it's written off the top of my head.

To remove a specific variable from the session use:

session_unregister('variableName');

(see documentation) or

unset($_SESSION['variableName']);

NOTE: session_unregister() has been DEPRECATED as of PHP 5.3.0 and REMOVED as of PHP 5.4.0.

You'll need to use UNION to combine the results of two queries. In your case:

SELECT ChargeNum, CategoryID, SUM(Hours)
FROM KnownHours
GROUP BY ChargeNum, CategoryID
UNION ALL
SELECT ChargeNum, 'Unknown' AS CategoryID, SUM(Hours)
FROM UnknownHours
GROUP BY ChargeNum

Note - If you use UNION ALL as in above, it's no slower than running the two queries separately as it does no duplicate-checking.

This is for Color to Brush....

you can't convert it, you have to make a new brush....

SolidColorBrush brush = new SolidColorBrush( myColor );

now, if you need it in XAML, you COULD make a custom value converter and use that in a binding

yes, using *arg passing args to a function will make python unpack the values in arg and pass it to the function.

so:

>>> def printer(*args):
 print args


>>> printer(2,3,4)
(2, 3, 4)
>>> printer(*range(2, 5))
(2, 3, 4)
>>> printer(range(2, 5))
([2, 3, 4],)

You don't need to apply to_date() to sysdate. It is already there:

select 1
from dual 
WHERE sysdate BETWEEN TO_DATE('28/02/2014', 'DD/MM/YYYY') AND TO_DATE('20/06/2014', 'DD/MM/YYYY');

If you are concerned about the time component on the date, then use trunc():

select 1
from dual 
WHERE trunc(sysdate) BETWEEN TO_DATE('28/02/2014', 'DD/MM/YYYY') AND
                             TO_DATE('20/06/2014', 'DD/MM/YYYY');

$var ??= '';

PHP 7.0+; with the null coalescing operator

$var = $var ?? '';

Or for all/older versions with isset:

$var = isset($var) ? $var : '';

or

!isset($var) && $var = '';

I had a similar need, and found this great little extension of the Twitter Bootstrap Popover by Lee Carmichael, called BootstrapX - clickover. He also has some usage examples here. Basically it will change the popover into an interactive component which will close when you click elsewhere on the page, or on a close button within the popover. This will also allow multiple popovers open at once and a bunch of other nice features.

Plugin can be found here.

Usage example

<button rel="clickover" data-content="Show something here. 
    <button data-dismiss='clickover'
    >Close Clickover</button>"
>Show clickover</button>

javascript:

// load click overs using 'rel' attribute
$('[rel="clickover"]').clickover();

In SQL Management Studio, right-click on a database and select "Properties" from the context menu. Look at the "Size" figure.

The solution env TZ='Europe/Amsterdam' node server.js from @uhef works in cases where your app doesn't work with forked process, but when you are working with forked process, specially when you launch your app with a building tool like gulp , the command gulp will take the env values, but the process created by gulp not (your app).

To solve this, you have to do:

$ export TZ="Europe/Amsterdam"; gulp myTask

This will set the TZ environment variable for all the process started in the console you are working on, included all the subsequents process executed after the gulp command in the same console without the need to execute them with the prefix export TZ="Europe/Amsterdam"; again.

The xcodebuild tool can build and export archive products with the -exportArchive flag (as of Xcode 5). The export step was previously only possible via the Xcode Organizer UI.

First archive your app:

xcodebuild -scheme <scheme name> archive

Given $ARCHIVE_PATH (the path to the .xcarchive file), export the app from the archive with one of the following:

iOS .ipa file:

xcodebuild -exportArchive -exportFormat ipa -archivePath "$ARCHIVE_PATH" -exportPath "myApp.ipa" -exportProvisioningProfile "My App Provisioning profile"

Mac .app file:

xcodebuild -exportArchive -exportFormat app -archivePath "$ARCHIVE_PATH" -exportPath "myApp.app" -exportSigningIdentity "Developer ID Application: My Software Company"

In both commands the -exportProvisioningProfile and -exportSigningIdentity arguments are optional. man xcodebuild for details on the semantics. In these examples, the provisioning profile for the iOS build specified an AdHoc distribution provisioning profile, and the signing identity for the Mac app specified a Developer ID for export as a 3rd party application (i.e. not distributed via the Mac App Store).

I know this is just syntactic sugar and only applicable in .net but what about extension method...

public static class RudiGroblerExtensions
{
    public static bool IsOdd(this int i)
    {
        return ((i % 2) != 0);
    }
}

Now you can do the following

int i = 5;
if (i.IsOdd())
{
    // Do something...
}

Your function would work like this:

CREATE OR REPLACE FUNCTION prc_tst_bulk(sql text)
RETURNS TABLE (name text, rowcount integer) AS 
$$
BEGIN

RETURN QUERY EXECUTE '
WITH v_tb_person AS (' || sql || $x$)
SELECT name, count(*)::int FROM v_tb_person WHERE nome LIKE '%a%' GROUP BY name
UNION
SELECT name, count(*)::int FROM v_tb_person WHERE gender = 1 GROUP BY name$x$;

END     
$$ LANGUAGE plpgsql;

Call:

SELECT * FROM prc_tst_bulk($$SELECT a AS name, b AS nome, c AS gender FROM tbl$$)

• You cannot mix plain and dynamic SQL the way you tried to do it. The whole statement is either all dynamic or all plain SQL. So I am building one dynamic statement to make this work. You may be interested in the chapter about executing dynamic commands in the manual.

• The aggregate function count() returns bigint, but you had rowcount defined as integer, so you need an explicit cast ::int to make this work

• I use dollar quoting to avoid quoting hell.

However, is this supposed to be a honeypot for SQL injection attacks or are you seriously going to use it? For your very private and secure use, it might be ok-ish - though I wouldn't even trust myself with a function like that. If there is any possible access for untrusted users, such a function is a loaded footgun. It's impossible to make this secure.

Craig (a sworn enemy of SQL injection!) might get a light stroke, when he sees what you forged from his piece of code in the answer to your preceding question. :)

The query itself seems rather odd, btw. But that's beside the point here.

using programetically

           // Set ListView divider color
            lv.setDivider(new ColorDrawable(Color.parseColor("#FF4A4D93")));

            // set ListView divider height
            lv.setDividerHeight(2);

Generally it's not recommended to gather statistics so frequent on the whole database unless you have a strong justification for that, such as a bulk insert or big data change happen frequently on the database. gathering statistics on the database in this frequency MAY change the queries execution plan to a new poor execution plans, the thing may cost you much time trying to tune every query affected by the new poor plans, this is why you should test the impact of gathering new statistics on a test database, or in case you don't have the time or the man power for that, at least you should keep a fallback plan by backing up the original statics before you gather new ones, so in case you gather a new statistics and then the queries didn't perform as expected, you can easily restore back the original statistics.

There is a very useful script can help you backup original statistics and gather new ones and provide you with SQL command you can use to restore back the original statics in case the thing didn't go as expected after gathering new statistics. You can find the script in this link: http://dba-tips.blogspot.com/2014/09/script-to-ease-gathering-statistics-on.html

request.getRequestURI().substring(request.getContextPath().length())

Yes you can do it yourself. It is just a matter of grabbing the sources of the page and parsing them the way you want.

There are various possibilities. A good combo is using python-requests (built on top of urllib2, it is urllib.request in Python3) and BeautifulSoup4, which has its methods to select elements and also permits CSS selectors:

import requests
from BeautifulSoup4 import BeautifulSoup as bs
request = requests.get("http://foo.bar")
soup = bs(request.text) 
some_elements = soup.find_all("div", class_="myCssClass")

Some will prefer xpath parsing or jquery-like pyquery, lxml or something else.

When the data you want is produced by some JavaScript, the above won't work. You either need python-ghost or Selenium. I prefer the latter combined with PhantomJS, much lighter and simpler to install, and easy to use:

from selenium import webdriver
client = webdriver.PhantomJS()
client.get("http://foo")
soup = bs(client.page_source)

I would advice to start your own solution. You'll understand Scrapy's benefits doing so.

ps: take a look at scrapely: https://github.com/scrapy/scrapely

Here is what I did to solve just by 2 ways:

1. make ID column as int type

2. if you are using autogenerate in ID dont assing value in the setter of ID. If your mapping the some then sometimes autogenetated ID is not concedered. (I dont know why)

3. try using @GeneratedValue(strategy=GenerationType.SEQUENCE) if possible

Because some images could have less than 500px of height, it's better to keep the auto-adjust, so i recommend the following:

<div class="carousel-inner" role="listbox" style="max-width:900px; max-height:600px !important;">`

We need to specify the INITIAL_CONTEXT_FACTORY, PROVIDER_URL, USERNAME, PASSWORD etc. of JNDI to create an InitialContext.

In a standalone application, you can specify that as below

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, 
    "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://ldap.wiz.com:389");
env.put(Context.SECURITY_PRINCIPAL, "joeuser");
env.put(Context.SECURITY_CREDENTIALS, "joepassword");

Context ctx = new InitialContext(env);

But if you are running your code in a Java EE container, these values will be fetched by the container and used to create an InitialContext as below

System.getProperty(Context.PROVIDER_URL);

and

these values will be set while starting the container as JVM arguments. So if you are running the code in a container, the following will work

InitialContext ctx = new InitialContext();

paramiko finally worked for me after adding additional line, which is really important one (line 3):

import paramiko

p = paramiko.SSHClient()
p.set_missing_host_key_policy(paramiko.AutoAddPolicy())   # This script doesn't work for me unless this line is added!
p.connect("server", port=22, username="username", password="password")
stdin, stdout, stderr = p.exec_command("your command")
opt = stdout.readlines()
opt = "".join(opt)
print(opt)

Make sure that paramiko package is installed. Original source of the solution: Source

As others have noted, distutils.sysconfig has the relevant settings:

import distutils.sysconfig
print distutils.sysconfig.get_python_lib()

...though the default site.py does something a bit more crude, paraphrased below:

import sys, os
print os.sep.join([sys.prefix, 'lib', 'python' + sys.version[:3], 'site-packages'])

(it also adds ${sys.prefix}/lib/site-python and adds both paths for sys.exec_prefix as well, should that constant be different).

That said, what's the context? You shouldn't be messing with your site-packages directly; setuptools/distutils will work for installation, and your program may be running in a virtualenv where your pythonpath is completely user-local, so it shouldn't assume use of the system site-packages directly either.

In the future.

It's the "null coalescing operator", added in php 7.0. The definition of how it works is:

It returns its first operand if it exists and is not NULL; otherwise it returns its second operand.

So it's actually just isset() in a handy operator.

Those two are equivalent¹:

$foo = $bar ?? 'something';
$foo = isset($bar) ? $bar : 'something';

¹There is a difference: In case of ??, the first expression is evaluated only once, as opposed to ? :, where the expression is first evaluated in the condition section, then the second time in the "answer" section.

Why setContentView() in Android Had Been So Popular Till Now?

setContentView(int layoutid) - method of activity class. It shows layout on screen.

R.layout.main - is an integer number implemented in nested layout class of R.java class file.

At the run time device will pick up their layout based on the id given in setcontentview() method.

public static void main(String[] args) {

try {

    DocumentBuilderFactory docFactory = DocumentBuilderFactory.newInstance();
    DocumentBuilder docBuilder = docFactory.newDocumentBuilder();
    Document doc = docBuilder.newDocument();
    Element rootElement = doc.createElement("CONFIGURATION");
    doc.appendChild(rootElement);
    Element browser = doc.createElement("BROWSER");
    browser.appendChild(doc.createTextNode("chrome"));
    rootElement.appendChild(browser);
    Element base = doc.createElement("BASE");
    base.appendChild(doc.createTextNode("http:fut"));
    rootElement.appendChild(base);
    Element employee = doc.createElement("EMPLOYEE");
    rootElement.appendChild(employee);
    Element empName = doc.createElement("EMP_NAME");
    empName.appendChild(doc.createTextNode("Anhorn, Irene"));
    employee.appendChild(empName);
    Element actDate = doc.createElement("ACT_DATE");
    actDate.appendChild(doc.createTextNode("20131201"));
    employee.appendChild(actDate);
    TransformerFactory transformerFactory = TransformerFactory.newInstance();
    Transformer transformer = transformerFactory.newTransformer();
    DOMSource source = new DOMSource(doc);
    StreamResult result = new StreamResult(new File("/Users/myXml/ScoreDetail.xml"));
    transformer.transform(source, result);
    System.out.println("File saved!");
  } catch (ParserConfigurationException pce) {
    pce.printStackTrace();
  } catch (TransformerException tfe) {
    tfe.printStackTrace();}}

The values in you XML is Hard coded.

Since iOS 11, you can use the native framework called PDFKit for displaying and manipulating PDFs.

After importing PDFKit, you should initialize a PDFView with a local or a remote URL and display it in your view.

if let url = Bundle.main.url(forResource: "example", withExtension: "pdf") {
    let pdfView = PDFView(frame: view.frame)
    pdfView.document = PDFDocument(url: url)
    view.addSubview(pdfView)
}

Read more about PDFKit in the Apple Developer documentation.

If you want to always display some value after decimal for example "12.00" or "12.23" Then use just like below , it worked for me

FormatNumber("145.231000",2) Which will display 145.23

FormatNumber("145",2) Which will display 145.00

With Java 8 you can write:

OffsetDateTime utc = OffsetDateTime.now(ZoneOffset.UTC);

To answer your comment, you can then convert it to a Date (unless you depend on legacy code I don't see any reason why) or to millis since the epochs:

Date date = Date.from(utc.toInstant());
long epochMillis = utc.toInstant().toEpochMilli();

Yes you can do it with simple JavaScript snippet:

document.addEventListener('mouseup', event => {  
    if(window.getSelection().toString().length){
       let exactText = window.getSelection().toString();        
    }
}

what you could do, is put an if statement around everything inside the loop that you want kept away from the 50. e.g.

for i in range(0, len(list)):
    if i != 50:
        x= listRow(list, i)
        for j in range (#0 to len(list) not including x#)

SP Initiated SSO

Bill the user: "Hey Jimmy, show me that report"

Jimmy the SP: "Hey, I'm not sure who you are yet. We have a process here so you go get yourself verified with Bob the IdP first. I trust him."

Bob the IdP: "I see Jimmy sent you here. Please give me your credentials."

Bill the user: "Hi I'm Bill. Here are my credentials."

Bob the IdP: "Hi Bill. Looks like you check out."

Bob the IdP: "Hey Jimmy. This guy Bill checks out and here's some additional information about him. You do whatever you want from here."

Jimmy the SP: "Ok cool. Looks like Bill is also in our list of known guests. I'll let Bill in."

IdP Initiated SSO

Bill the user: "Hey Bob. I want to go to Jimmy's place. Security is tight over there."

Bob the IdP: "Hey Jimmy. I trust Bill. He checks out and here's some additional information about him. You do whatever you want from here."

Jimmy the SP: "Ok cool. Looks like Bill is also in our list of known guests. I'll let Bill in."

I go into more detail here, but still keeping things simple: https://jorgecolonconsulting.com/saml-sso-in-simple-terms/.

Concise and memory efficient:

#!/usr/bin/env python
# file: grep.py
import re, sys

map(sys.stdout.write,(l for l in sys.stdin if re.search(sys.argv[1],l)))

It works like egrep (without too much error handling), e.g.:

cat input-file | grep.py "RE"

And here is the one-liner:

cat input-file | python -c "import re,sys;map(sys.stdout.write,(l for l in sys.stdin if re.search(sys.argv[1],l)))" "RE"

For anyone who stumbles across this in the future, this is how you do it:

xl.Range("A1:A1").Style := "Bad"
xl.Range("A1:A1").Style := "Good"
xl.Range("A1:A1").Style := "Neutral"

An easy way to check on things like this is to open excel and record a macro. In this case I recorded a macro where I just formatted the cell to "Bad". Once you've recorded the macro, just go in and edit it and it will essentially give you the code. It will require a little translation on your part, but here is what the macro looks like when I edit it:

 Selection.Style = "Bad"

As you can see, it's pretty easy to make the jump to AHK from what excel provides.

Python bindings to libmagic

All the different answers on this topic are very confusing, so I’m hoping to give a bit more clarity with this overview of the different bindings of libmagic. Previously mammadori gave a short answer listing the available option.

libmagic

• module name: magic
• pypi: file-magic
• source: https://github.com/file/file/tree/master/python

When determining a files mime-type, the tool of choice is simply called file and its back-end is called libmagic. (See the Project home page.) The project is developed in a private cvs-repository, but there is a read-only git mirror on github.

Now this tool, which you will need if you want to use any of the libmagic bindings with python, already comes with its own python bindings called file-magic. There is not much dedicated documentation for them, but you can always have a look at the man page of the c-library: man libmagic. The basic usage is described in the readme file:

import magic

detected = magic.detect_from_filename('magic.py')
print 'Detected MIME type: {}'.format(detected.mime_type)
print 'Detected encoding: {}'.format(detected.encoding)
print 'Detected file type name: {}'.format(detected.name)

Apart from this, you can also use the library by creating a Magic object using magic.open(flags) as shown in the example file.

Both toivotuo and ewr2san use these file-magic bindings included in the file tool. They mistakenly assume, they are using the python-magic package. This seems to indicate, that if both file and python-magic are installed, the python module magic refers to the former one.

python-magic

• module name: magic
• pypi: python-magic
• source: https://github.com/ahupp/python-magic

This is the library that Simon Zimmermann talks about in his answer and which is also employed by Claude COULOMBE as well as Gringo Suave.

filemagic

• module name: magic
• pypi: filemagic
• source: https://github.com/aliles/filemagic

Note: This project was last updated in 2013!

Due to being based on the same c-api, this library has some similarity with file-magic included in libmagic. It is only mentioned by mammadori and no other answer employs it.

My favorite way to do it is with git log's -G option (added in version 1.7.4).

-G<regex>
       Look for differences whose added or removed line matches the given <regex>.

There is a subtle difference between the way the -G and -S options determine if a commit matches:

• The -S option essentially counts the number of times your search matches in a file before and after a commit. The commit is shown in the log if the before and after counts are different. This will not, for example, show commits where a line matching your search was moved.
• With the -G option, the commit is shown in the log if your search matches any line that was added, removed, or changed.

Take this commit as an example:

diff --git a/test b/test
index dddc242..60a8ba6 100644
--- a/test
+++ b/test
@@ -1 +1 @@
-hello hello
+hello goodbye hello

Because the number of times "hello" appears in the file is the same before and after this commit, it will not match using -Shello. However, since there was a change to a line matching hello, the commit will be shown using -Ghello.

If is a package then you can get the source for that with:

    select text from all_source where name = 'PADCAMPAIGN' 
    and type = 'PACKAGE BODY'
    order by line;

Oracle doesn't store the source for a sub-program separately, so you need to look through the package source for it.

Note: I've assumed you didn't use double-quotes when creating that package, but if you did , then use

    select text from all_source where name = 'pAdCampaign' 
    and type = 'PACKAGE BODY'
    order by line;

A person might get this while working with factory functions, so I can confirm this is valid syntax:

$user = factory(User::class, 1)->create()->first();

You might see the collection instance error if you do something like:

$user = factory(User::class, 1)->create()->id;

so change it to:

$user = factory(User::class, 1)->create()->first()->id;

One example more :)

double a = 1.00

if(floor(a) == a) {
   // a is an integer
} else {
   //a is not an integer.
}

In this example, ceil can be used and have the exact same effect.

blocking the main thread is not a good style for node because in most cases more then one person is using it. You should use settimeout/setinterval in combination with callbacks.

You can check for type of a variable using __name__ of a type.

Ex:

>>> a = [1,2,3,4]  
>>> b = 1  
>>> type(a).__name__
'list'
>>> type(a).__name__ == 'list'
True
>>> type(b).__name__ == 'list'
False
>>> type(b).__name__
'int'

Here is some working code: http://jsfiddle.net/mihaifm/W7XNU/200/

$('body').tooltip({
    selector: '[rel="tooltip"]'
});

$(".btn").click(function(e) {
    if (! $(this).hasClass("disabled"))
    {
        $(".disabled").removeClass("disabled").attr("rel", null);

        $(this).addClass("disabled").attr("rel", "tooltip");
    }
});

The idea is to add the tooltip to a parent element with the selector option, and then add/remove the rel attribute when enabling/disabling the button.

I know that JPA entities must have primary key but I can't change database structure due to reasons beyond my control.

More precisely, a JPA entity must have some Id defined. But a JPA Id does not necessarily have to be mapped on the table primary key (and JPA can somehow deal with a table without a primary key or unique constraint).

Is it possible to create JPA (Hibernate) entities that will be work with database structure like this?

If you have a column or a set of columns in the table that makes a unique value, you can use this unique set of columns as your Id in JPA.

If your table has no unique columns at all, you can use all of the columns as the Id.

And if your table has some id but your entity doesn't, make it an Embeddable.

An example usage:

>>> s = 'Hello world'
>>> t = buffer(s, 6, 5)
>>> t
<read-only buffer for 0x10064a4b0, size 5, offset 6 at 0x100634ab0>
>>> print t
world

The buffer in this case is a sub-string, starting at position 6 with length 5, and it doesn't take extra storage space - it references a slice of the string.

This isn't very useful for short strings like this, but it can be necessary when using large amounts of data. This example uses a mutable bytearray:

>>> s = bytearray(1000000)   # a million zeroed bytes
>>> t = buffer(s, 1)         # slice cuts off the first byte
>>> s[1] = 5                 # set the second element in s
>>> t[0]                     # which is now also the first element in t!
'\x05'

This can be very helpful if you want to have more than one view on the data and don't want to (or can't) hold multiple copies in memory.

Note that buffer has been replaced by the better named memoryview in Python 3, though you can use either in Python 2.7.

Note also that you can't implement a buffer interface for your own objects without delving into the C API, i.e. you can't do it in pure Python.

To comment/uncomment one line, use: Ctrl + /.

To comment/uncomment a block, use: Ctrl + Shift + /.

>>> import requests
>>> response = requests.get('https://website.com/id', headers={'Authorization': 'access_token myToken'})

Also useful is Object.toSource() for debugging purposes, where you want to show the object and its properties for debugging purposes. This is a generic Javascript (not jQuery) function, however it only works in "modern" browsers.

this method also encounter a deprecate warning:

org.junit.Assert.assertEquals(float expected,float actual) //deprecated

It is because currently junit prefer a third parameter rather than just two float variables input.

The third parameter is delta:

public static void assertEquals(double expected,double actual,double delta) //replacement

The problem can not be solved with xCode Upload Process. I was facing same issues few days ago when submitting few of my apps and all apps showing same error. After many tries, I used Application Loader to upload app and it worked.

First go to xcode -> product menu -> archive Select Export for Appstore Save IPA file Now Open Application loader by going to xCode -> xCode Menu -> Open Developer Tool -> Application Loader Login with the credentials of account, and select the IPA file. Submit it! It works!

use DateTime.Now

try this:

DateTime.Now.ToString("yyyy/MM/dd HH:mm:ss")

DECLARE @CMonth int=null
DECLARE @lCYear int=null

SET @lCYear=(SELECT  DATEPART(YEAR,GETDATE()))
SET @CMonth=(SELECT  DATEPART(MONTH,GETDATE()))

You need an HTML element for each column in your layout.

I’d suggest:

HTML

<div class="two-col">
    <div class="col1">
        <label for="field1">Field One:</label>
        <input id="field1" name="field1" type="text">
    </div>

    <div class="col2">
        <label for="field2">Field Two:</label>
        <input id="field2" name="field2" type="text">
    </div>
</div>

CSS

.two-col {
    overflow: hidden;/* Makes this div contain its floats */
}

.two-col .col1,
.two-col .col2 {
    width: 49%;
}

.two-col .col1 {
    float: left;
}

.two-col .col2 {
    float: right;
}

.two-col label {
    display: block;
}

<td align="center">

or via css, which is the preferred method any more...

<td style="text-align: center;">

Found a workaround solution. Say that you want to scroll to an div, Element here for example, and you want to have a spacing of 20px above it. Set the ref to a created div above it:

<div ref={yourRef} style={{position: 'relative', bottom: 20}}/> <Element />

Doing so will create this spacing that you want.

If you have a header, create an empty div as well behind the header and assign to it a height equal to the height of the header and reference it.

Swift 4.0 code (Here we go again)

The called action should marked like this because that is the syntax for swift function for exporting functions into objective c language.

@objc func deleteAction(sender: UIButton) {
}

create some working button:

let deleteButton = UIButton(type: .roundedRect)
deleteButton.setTitle("Delete", for: [])
deleteButton.addTarget(self, action: #selector( 
MyController.deleteAction(sender:)), for: .touchUpInside)

If you want a super class to call a function from a subclass, the cleanest way is to define an abstract pattern, in this manner you explicitly know the method exists somewhere and must be overridden by a subclass.

This is as an example, normally you do not call a sub method within the constructor as the sub instance is not initialized yet… (reason why you have an "undefined" in your question's example)

abstract class A {
    // The abstract method the subclass will have to call
    protected abstract doStuff():void;

    constructor(){
     alert("Super class A constructed, calling now 'doStuff'")
     this.doStuff();
    }
}

class B extends A{

    // Define here the abstract method
    protected doStuff()
    {
        alert("Submethod called");
    }
}

var b = new B();

Test it Here

And if like @Max you really want to avoid implementing the abstract method everywhere, just get rid of it. I don't recommend this approach because you might forget you are overriding the method.

abstract class A {
    constructor() {
        alert("Super class A constructed, calling now 'doStuff'")
        this.doStuff();
    }

    // The fallback method the subclass will call if not overridden
    protected doStuff(): void {
        alert("Default doStuff");
    };
}

class B extends A {
    // Override doStuff()
    protected doStuff() {
        alert("Submethod called");
    }
}

class C extends A {
    // No doStuff() overriding, fallback on A.doStuff()
}

var b = new B();
var c = new C();

You can use the PHP function apc_clear_cache.

Calling apc_clear_cache() will clear the system cache and calling apc_clear_cache('user') will clear the user cache.

As of today (1st November, 2020), Google provided a provision of Universal URL which works quite efficiently on cross-platforms and thus, Google recommends this method.

In distributable software, I dont want my customers mucking about in the database by themselves. The program reads and writes it all by itself. The only reason for a user to touch the DB file is to take a backup copy. Therefore I have named it whatever_records.db

The simple .db extension tells the user that it is a binary data file and that's all they have to know. Calling it .sqlite invites the interested user to open it up and mess something up!

Totally depends on your usage scenario I suppose.

2-D Array Dynamic Memory Allocation

int **a,i;

I had this error with WAMP 3.0.6 with MySql 5.7.14.

Solution:

change line 70 (if your ini file is untouched) in c:\wamp\bin\mysql\mysql5.7.14\my.ini file from

sql-mode= "STRICT_ALL_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_ZERO_DATE,NO_ZERO_IN_DATE,NO_AUTO_CREATE_USER"

to

sql-mode="ERROR_FOR_DIVISION_BY_ZERO,NO_ZERO_DATE,NO_ZERO_IN_DATE,NO_AUTO_CREATE_USER"

and restart all services.

This will disable strict mode. As per the documentation, “strict mode” means a mode with either or both STRICT_TRANS_TABLES or STRICT_ALL_TABLES enabled. The documentation says:

"The default SQL mode in MySQL 5.7 includes these modes: ONLY_FULL_GROUP_BY, STRICT_TRANS_TABLES, NO_ZERO_IN_DATE, NO_ZERO_DATE, ERROR_FOR_DIVISION_BY_ZERO, NO_AUTO_CREATE_USER, and NO_ENGINE_SUBSTITUTION."

$_SERVER['SERVER_NAME'] is based on your web servers configuration. $_SERVER['HTTP_HOST'] is based on the request from the client.

var is_chrome = browseris.chrome

or check ather browsers:

browseris.firefox
browseris.ie
browseris.safari

and olso you can check the version like browseris.chrome7up and etc.

check all existing information in the 'browseris' object

Had this error too, the cause was simple, but not obvious: incorrect password. Not sure why I didn't get just "Login failed" from freshly installed SQL 2016 server.

As I understand POD (PlainOldData) is just a raw data - it does not need:

• to be constructed,
• to be destroyed,
• to have custom operators.
• Must not have virtual functions,
• and must not override operators.

How to check if something is a POD? Well, there is a struct for that called std::is_pod:

namespace std {
// Could use is_standard_layout && is_trivial instead of the builtin.
template<typename _Tp>
  struct is_pod
  : public integral_constant<bool, __is_pod(_Tp)>
  { };
}

(From header type_traits)

SIMPLEST APPROACH:

Create an xml file rounded_fg.xml under res/drawable/ folder of your app. The content of rounded_fg.xml is as follows,

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:innerRadiusRatio="2"
    android:shape="ring"
    android:thicknessRatio="1"
    android:useLevel="false">
    <gradient
        android:type="radial"
        android:gradientRadius="8dp"
        android:endColor="@color/white"
       />
</shape>

You can match endColor with ImageView container layout background & gradientRadius may be any value as per your requirements (<=36dp).

Now use this drawable as foreground for your imageview as follows,

 <ImageView
     android:layout_width="55dp"
     android:layout_height="55dp" 
     android:foreground="@drawable/rounded_fg" />

Works perfect with square images and/or imageview.

If you're in local machine then use this command

/usr/local/mysql/bin/mysqldump -h127.0.0.1 --port = 3306 -u [username] -p [password] --databases [db_name] --tables [tablename] > /to/path/tablename.sql;

For remote machine, use below one

/usr/local/mysql/bin/mysqldump -h [remoteip] --port = 3306 -u [username] -p [password] --databases [db_name] --tables [tablename] > /to/path/tablename.sql;

Operating Systems: Internals and Design Principles
William Stallings
8º Edition

Deadlock: A situation in which two or more processes are unable to proceed because each is waiting for one the others to do something.

For example, consider two processes, P1 and P2, and two resources, R1 and R2. Suppose that each process needs access to both resources to perform part of its function. Then it is possible to have the following situation: the OS assigns R1 to P2, and R2 to P1. Each process is waiting for one of the two resources. Neither will release the resource that it already owns until it has acquired the other resource and performed the function requiring both resources. The two processes are deadlocked

Livelock: A situation in which two or more processes continuously change their states in response to changes in the other process(es) without doing any useful work:

Starvation: A situation in which a runnable process is overlooked indefinitely by the scheduler; although it is able to proceed, it is never chosen.

Suppose that three processes (P1, P2, P3) each require periodic access to resource R. Consider the situation in which P1 is in possession of the resource, and both P2 and P3 are delayed, waiting for that resource. When P1 exits its critical section, either P2 or P3 should be allowed access to R. Assume that the OS grants access to P3 and that P1 again requires access before P3 completes its critical section. If the OS grants access to P1 after P3 has finished, and subsequently alternately grants access to P1 and P3, then P2 may indefinitely be denied access to the resource, even though there is no deadlock situation.

APPENDIX A - TOPICS IN CONCURRENCY

Deadlock Example

If both processes set their flags to true before either has executed the while statement, then each will think that the other has entered its critical section, causing deadlock.

/* PROCESS 0 */
flag[0] = true;            // <- get lock 0
while (flag[1])            // <- is lock 1 free?
    /* do nothing */;      // <- no? so I wait 1 second, for example
                           // and test again.
                           // on more sophisticated setups we can ask
                           // to be woken when lock 1 is freed
/* critical section*/;     // <- do what we need (this will never happen)
flag[0] = false;           // <- releasing our lock

 /* PROCESS 1 */
flag[1] = true;
while (flag[0])
    /* do nothing */;
/* critical section*/;
flag[1] = false;

Livelock Example

/* PROCESS 0 */
flag[0] = true;          // <- get lock 0
while (flag[1]){         
    flag[0] = false;     // <- instead of sleeping, we do useless work
                         //    needed by the lock mechanism
    /*delay */;          // <- wait for a second
    flag[0] = true;      // <- and restart useless work again.
}
/*critical section*/;    // <- do what we need (this will never happen)
flag[0] = false; 

/* PROCESS 1 */
flag[1] = true;
while (flag[0]) {
    flag[1] = false;
    /*delay */;
    flag[1] = true;
}
/* critical section*/;
flag[1] = false;

[...] consider the following sequence of events:

• P0 sets flag[0] to true.
• P1 sets flag[1] to true.
• P0 checks flag[1].
• P1 checks flag[0].
• P0 sets flag[0] to false.
• P1 sets flag[1] to false.
• P0 sets flag[0] to true.
• P1 sets flag[1] to true.

This sequence could be extended indefinitely, and neither process could enter its critical section. Strictly speaking, this is not deadlock, because any alteration in the relative speed of the two processes will break this cycle and allow one to enter the critical section. This condition is referred to as livelock. Recall that deadlock occurs when a set of processes wishes to enter their critical sections but no process can succeed. With livelock, there are possible sequences of executions that succeed, but it is also possible to describe one or more execution sequences in which no process ever enters its critical section.

And what about spinlocks?

Spinlock is a technique to avoid the cost of the OS lock mechanism. Typically you would do:

try
{
   lock = beginLock();
   doSomething();
}
finally
{
   endLock();
}

A problem start to appear when beginLock() costs much more than doSomething(). In very exagerated terms, imagine what happens when the beginLock costs 1 second, but doSomething cost just 1 millisecond.

In this case if you waited 1 millisecond, you would avoid being hindered for 1 second.

Why the beginLock would cost so much? If the lock is free is does not cost a lot (see https://stackoverflow.com/a/49712993/5397116), but if the lock is not free the OS will "freeze" your thread, setup a mechanism to wake you when the lock is freed, and then wake you again in the future.

All of this is much more expensive than some loops checking the lock. That is why sometimes is better to do a "spinlock".

For example:

void beginSpinLock(lock)
{
   if(lock) loopFor(1 milliseconds);
   else 
   {
     lock = true;
     return;
   }

   if(lock) loopFor(2 milliseconds);
   else 
   {
     lock = true;
     return;
   }

   // important is that the part above never 
   // cause the thread to sleep.
   // It is "burning" the time slice of this thread.
   // Hopefully for good.

   // some implementations fallback to OS lock mechanism
   // after a few tries
   if(lock) return beginLock(lock);
   else 
   {
     lock = true;
     return;
   }
}

If your implementation is not careful, you can fall on livelock, spending all CPU on the lock mechanism.

Also see:

https://preshing.com/20120226/roll-your-own-lightweight-mutex/
Is my spin lock implementation correct and optimal?

Summary:

Deadlock: situation where nobody progress, doing nothing (sleeping, waiting etc..). CPU usage will be low;

Livelock: situation where nobody progress, but CPU is spent on the lock mechanism and not on your calculation;

Starvation: situation where one procress never gets the chance to run; by pure bad luck or by some of its property (low priority, for example);

Spinlock: technique of avoiding the cost waiting the lock to be freed.

Check out Padolsey's article on DOM find and replace, as well as the library to implement the described algorithm.

In this sample usage, I replace all text inside a <div id="content"> that looks like a US telephone number with a tel: scheme link:

findAndReplaceDOMText(document.getElementById('content'), {
    find:/\b(\d\d\d-\d\d\d-\d\d\d\d)\b/g,
    replace:function (portion) {
        var a = document.createElement('a');
        a.className = 'telephone';
        a.href = 'tel:' + portion.text.replace(/\D/g, '');
        a.textContent = portion.text;
        return a;
    }
});

I tried both the 32-bit and 64-bit installers of both Oracle and IBM Java on Windows, and the presence of C:\Windows\SysWOW64\java.exe seems to be a reliable way to determine that 32-bit Java is available. I haven't tested older versions of these installers, but this at least looks like it should be a reliable way to test, for the most recent versions of Java.

#include <iostream>
#include <string.h>
using namespace std;
int main() {
   string s="000101";
   cout<<s<<"\n";
   int a = stoi(s);
   cout<<a<<"\n";
   s=to_string(a);
   s+='1';
   cout<<s;
   return 0;
}

Output:

• 000101
• 101
• 1011

Your best bet is to iterate over the members of the collection and see if any match what you are looking for. Trust me I have had to do this many times.

The second solution (which is much worse) is to catch the "Item not in collection" error and then set a flag to say the item does not exist.
