I searched long on this issue. There are several reasons causes this issue.

If you are facing when you and Swift code/library in an Objectice C project you should try Solution 1-2-3

If you are facing this issue with a new a Swift project Solution 4 will fit you best.

Solution 1:

Restart Xcode, then computer and iPhone

Solution 2:

Go to project build settings and set Embedded Content Contains Swift Code flag to YES

Solution 3:

Go to project build settings and add @executable_path/Frameworks to Runpath Search Paths option

Solution 4:

If none of above works, this should. Apple seems to be ninja patched certificates as mentioned in AirSign's post

At InHouse certificates

Subject: UID=269J2W3P2L, CN=iPhone Distribution: Company Name, O=Company Name, C=FR

they added a new field named OU

Subject: UID=269J2W3P2L, CN=iPhone Distribution: Company Name, OU=269J2W3P2L, O=Company Name, C=FR

so you should just recreate certificate and provision

I already found the answer

Swift 4

let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)
let nextViewController = storyBoard.instantiateViewController(withIdentifier: "nextView") as! NextViewController
self.present(nextViewController, animated:true, completion:nil)

Swift 3

let storyBoard : UIStoryboard = UIStoryboard(name: "Main", bundle:nil)

let nextViewController = storyBoard.instantiateViewControllerWithIdentifier("nextView") as NextViewController
self.presentViewController(nextViewController, animated:true, completion:nil)

Make sure you are not dynamically applying relative constraints to a view which is not yet there in view hierarchy.

UIView *bottomView = [[UIView alloc] initWithFrame:CGRectZero];
[self.view addSubview:bottomView];

bottomConstraint = [NSLayoutConstraint constraintWithItem:bottomView
                                                attribute:NSLayoutAttributeBottom
                                                relatedBy:NSLayoutRelationEqual
                                                   toItem:self.view
                                                attribute:NSLayoutAttributeBottom
                                               multiplier:1
                                                 constant:0];
bottomConstraint.active = YES;

In above example, bottomView has been made part of view hierarchy before applying relative constraints on it.

I spend a hour finding out what was wrong.. But Clean Project did the trick.

Build -> Clean All

The accepted solution is probably also working.. but this was enough for me.

SIGABRT means in general that there is an uncaught exception. There should be more information on the console.

If you need to change only size (Swift 4.0):

button.titleLabel?.font = button.titleLabel?.font.withSize(12)

If you want to run your command in parallel for each line you can use GNU Parallel

parallel -a <your file> <program>

Each line of your file will be passed to program as an argument. By default parallel runs as many threads as your CPUs count. But you can specify it with -j

The window is the actual global object.

The screen is the screen, it contains properties about the user's display.

The document is where the DOM is.

To make the code clear that you are intending to get the first row, CodeIgniter now allows you to use:

if ($query->num_rows() > 0) {
    return $query->first_row();
}

To retrieve the first row.

You can use the following shortcut for code formatting: Ctrl+Alt+L

You could try using HTML5s sessionStorage it lasts for the duration on the page session. A page session lasts for as long as the browser is open and survives over page reloads and restores. Opening a page in a new tab or window will cause a new session to be initiated.

sessionStorage.setItem("username", "John");

To change the encoding of your database:

1. Dump your database
2. Drop your database,
3. Create new database with the different encoding
4. Reload your data.

Make sure the client encoding is set correctly during all this.

Please be aware that the accepted answer is a bit incomplete. Yes, at the most basic level Collation handles sorting. BUT, the comparison rules defined by the chosen Collation are used in many places outside of user queries against user data.

If "What does COLLATE SQL_Latin1_General_CP1_CI_AS do?" means "What does the COLLATE clause of CREATE DATABASE do?", then:

The COLLATE {collation_name} clause of the CREATE DATABASE statement specifies the default Collation of the Database, and not the Server; Database-level and Server-level default Collations control different things.

Server (i.e. Instance)-level controls:

• Database-level Collation for system Databases: master, model, msdb, and tempdb.
• Due to controlling the DB-level Collation of tempdb, it is then the default Collation for string columns in temporary tables (global and local), but not table variables.
• Due to controlling the DB-level Collation of master, it is then the Collation used for Server-level data, such as Database names (i.e. name column in sys.databases), Login names, etc.
• Handling of parameter / variable names
• Handling of cursor names
• Handling of GOTO labels
• Default Collation used for newly created Databases when the COLLATE clause is missing

Database-level controls:

• Default Collation used for newly created string columns (CHAR, VARCHAR, NCHAR, NVARCHAR, TEXT, and NTEXT -- but don't use TEXT or NTEXT) when the COLLATE clause is missing from the column definition. This goes for both CREATE TABLE and ALTER TABLE ... ADD statements.
• Default Collation used for string literals (i.e. 'some text') and string variables (i.e. @StringVariable). This Collation is only ever used when comparing strings and variables to other strings and variables. When comparing strings / variables to columns, then the Collation of the column will be used.
• The Collation used for Database-level meta-data, such as object names (i.e. sys.objects), column names (i.e. sys.columns), index names (i.e. sys.indexes), etc.
• The Collation used for Database-level objects: tables, columns, indexes, etc.

Also:

• ASCII is an encoding which is 8-bit (for common usage; technically "ASCII" is 7-bit with character values 0 - 127, and "ASCII Extended" is 8-bit with character values 0 - 255). This group is the same across cultures.
• The Code Page is the "extended" part of Extended ASCII, and controls which characters are used for values 128 - 255. This group varies between each culture.
• Latin1 does not mean "ASCII" since standard ASCII only covers values 0 - 127, and all code pages (that can be represented in SQL Server, and even NVARCHAR) map those same 128 values to the same characters.

If "What does COLLATE SQL_Latin1_General_CP1_CI_AS do?" means "What does this particular collation do?", then:

• Because the name start with SQL_, this is a SQL Server collation, not a Windows collation. These are definitely obsolete, even if not officially deprecated, and are mainly for pre-SQL Server 2000 compatibility. Although, quite unfortunately SQL_Latin1_General_CP1_CI_AS is very common due to it being the default when installing on an OS using US English as its language. These collations should be avoided if at all possible.

  Windows collations (those with names not starting with SQL_) are newer, more functional, have consistent sorting between VARCHAR and NVARCHAR for the same values, and are being updated with additional / corrected sort weights and uppercase/lowercase mappings. These collations also don't have the potential performance problem that the SQL Server collations have: Impact on Indexes When Mixing VARCHAR and NVARCHAR Types.

• Latin1_General is the culture / locale.
  • For NCHAR, NVARCHAR, and NTEXT data this determines the linguistic rules used for sorting and comparison.
  • For CHAR, VARCHAR, and TEXT data (columns, literals, and variables) this determines the:
    • linguistic rules used for sorting and comparison.
    • code page used to encode the characters. For example, Latin1_General collations use code page 1252, Hebrew collations use code page 1255, and so on.

• CP{code_page} or {version}

  • For SQL Server collations: CP{code_page}, is the 8-bit code page that determines what characters map to values 128 - 255. While there are four code pages for Double-Byte Character Sets (DBCS) that can use 2-byte combinations to create more than 256 characters, these are not available for the SQL Server collations.

  • For Windows collations: {version}, while not present in all collation names, refers to the SQL Server version in which the collation was introduced (for the most part). Windows collations with no version number in the name are version 80 (meaning SQL Server 2000 as that is version 8.0). Not all versions of SQL Server come with new collations, so there are gaps in the version numbers. There are some that are 90 (for SQL Server 2005, which is version 9.0), most are 100 (for SQL Server 2008, version 10.0), and a small set has 140 (for SQL Server 2017, version 14.0).

    I said "for the most part" because the collations ending in _SC were introduced in SQL Server 2012 (version 11.0), but the underlying data wasn't new, they merely added support for supplementary characters for the built-in functions. So, those endings exist for version 90 and 100 collations, but only starting in SQL Server 2012.

• Next you have the sensitivities, that can be in any combination of the following, but always specified in this order:
  • CS = case-sensitive or CI = case-insensitive
  • AS = accent-sensitive or AI = accent-insensitive
  • KS = Kana type-sensitive or missing = Kana type-insensitive
  • WS = width-sensitive or missing = width insensitive
  • VSS = variation selector sensitive (only available in the version 140 collations) or missing = variation selector insensitive

• Optional last piece:

  • _SC at the end means "Supplementary Character support". The "support" only affects how the built-in functions interpret surrogate pairs (which are how supplementary characters are encoded in UTF-16). Without _SC at the end (or _140_ in the middle), built-in functions don't see a single supplementary character, but instead see two meaningless code points that make up the surrogate pair. This ending can be added to any non-binary, version 90 or 100 collation.
  • _BIN or _BIN2 at the end means "binary" sorting and comparison. Data is still stored the same, but there are no linguistic rules. This ending is never combined with any of the 5 sensitivities or _SC. _BIN is the older style, and _BIN2 is the newer, more accurate style. If using SQL Server 2005 or newer, use _BIN2. For details on the differences between _BIN and _BIN2, please see: Differences Between the Various Binary Collations (Cultures, Versions, and BIN vs BIN2).

  • _UTF8 is a new option as of SQL Server 2019. It's an 8-bit encoding that allows for Unicode data to be stored in VARCHAR and CHAR datatypes (but not the deprecated TEXT datatype). This option can only be used on collations that support supplementary characters (i.e. version 90 or 100 collations with _SC in their name, and version 140 collations). There is also a single binary _UTF8 collation (_BIN2, not _BIN).

    PLEASE NOTE: UTF-8 was designed / created for compatibility with environments / code that are set up for 8-bit encodings yet want to support Unicode. Even though there are a few scenarios where UTF-8 can provide up to 50% space savings as compared to NVARCHAR, that is a side-effect and has a cost of a slight hit to performance in many / most operations. If you need this for compatibility, then the cost is acceptable. If you want this for space-savings, you had better test, and TEST AGAIN. Testing includes all functionality, and more than just a few rows of data. Be warned that UTF-8 collations work best when ALL columns, and the database itself, are using VARCHAR data (columns, variables, string literals) with a _UTF8 collation. This is the natural state for anyone using this for compatibility, but not for those hoping to use it for space-savings. Be careful when mixing VARCHAR data using a _UTF8 collation with either VARCHAR data using non-_UTF8 collations or NVARCHAR data, as you might experience odd behavior / data loss. For more details on the new UTF-8 collations, please see: Native UTF-8 Support in SQL Server 2019: Savior or False Prophet?

as in this post, using .is and the attribute selector [], you can easily add a function (or prototype):

function hasAttr($sel,attr) {
    return $sel.is('['+attr+']');
}

This is very good discussion. I had one of those moments when I wished or lets say hoped (successfully that I might add) to reinvent the wheel be it a square one. Any ways above is good discussion, so any one coming here looking for what is the difference between Element property and attribute. here is my penny worth and I did have to find it out hard way. I would keep it simple so no extraordinary tech jargon.

suppose we have a variable calls 'A'. what we are used to is as following.

Below will throw an error because simply it put its is kind of object that can only have one property and that is singular left hand side = singular right hand side object. Every thing else is ignored and tossed out in bin.

let A = 'f';
A.b =2;
console.log(A.b);

who has decided that it has to be singular = singular. People who make JavaScript and html standards and thats how engines work.

Lets change the example.

let A = {};
A.b =2;
console.log(A.b);

This time it works ..... because we have explicitly told it so and who decided we can tell it in this case but not in previous case. Again people who make JavaScript and html standards.

I hope we are on this lets complicate it further

let A = {};
A.attribute ={};
A.attribute.b=5;
console.log(A.attribute.b); // will work

console.log(A.b); // will not work

What we have done is tree of sorts level 1 then sub levels of non-singular object. Unless you know what is where and and call it so it will work else no.

This is what goes on with HTMLDOM when its parsed and painted a DOm tree is created for each and every HTML ELEMENT. Each has level of properties per say. Some are predefined and some are not. This is where ID and VALUE bits come on. Behind the scene they are mapped on 1:1 between level 1 property and sun level property aka attributes. Thus changing one changes the other. This is were object getter ans setter scheme of things plays role.

let A = {
attribute :{
id:'',
value:''
},
getAttributes: function (n) {
    return this.attribute[n];
  },
setAttributes: function (n,nn){
this.attribute[n] = nn;
if(this[n]) this[n] = nn;
},
id:'',
value:''
};



A.id = 5;
console.log(A.id);
console.log(A.getAttributes('id'));

A.setAttributes('id',7)
console.log(A.id);
console.log(A.getAttributes('id'));

A.setAttributes('ids',7)
console.log(A.ids);
console.log(A.getAttributes('ids'));

A.idsss=7;
console.log(A.idsss);
console.log(A.getAttributes('idsss'));

This is the point as shown above ELEMENTS has another set of so called property list attributes and it has its own main properties. there some predefined properties between the two and are mapped as 1:1 e.g. ID is common to every one but value is not nor is src. when the parser reaches that point it simply pulls up dictionary as to what to when such and such are present.

All elements have properties and attributes and some of the items between them are common. What is common in one is not common in another.

In old days of HTML3 and what not we worked with html first then on to JS. Now days its other way around and so has using inline onlclick become such an abomination. Things have moved forward in HTML5 where there are many property lists accessible as collection e.g. class, style. In old days color was a property now that is moved to css for handling is no longer valid attribute.

Element.attributes is sub property list with in Element property.

Unless you could change the getter and setter of Element property which is almost high unlikely as it would break hell on all functionality is usually not writable off the bat just because we defined something as A.item does not necessarily mean Js engine will also run another line of function to add it into Element.attributes.item.

I hope this gives some headway clarification as to what is what. Just for the sake of this I tried Element.prototype.setAttribute with custom function it just broke loose whole thing all together, as it overrode native bunch of functions that set attribute function was playing behind the scene.

• ser1 = pd.Sereis(np.linspace(1, 10, 2))
• element = np.nan
• ser1 = ser1.append(pd.Series(element))

Try this:

<select>
    <option value="">&nbsp;
    <option>Option 1
    <option>Option 2
    <option>Option 3
</select>

Validates in HTML5. Works with required attribute in select element. Can be re-selected. Works in Google Chrome 45, Internet Explorer 11, Edge, Firefox 41.

You don't need two JScrollPanes.

Example:

JTextArea ta = new JTextArea();
JScrollPane sp = new JScrollPane(ta);  

// Add the scroll pane into the content pane
JFrame f = new JFrame();
f.getContentPane().add(sp);

You had thead in your selector, but there is no thead in your table. Also you had your selectors backwards. As you mentioned above, you wanted to be adding the tr class to the th, not vice-versa (although your comment seems to contradict what you wrote up above).

$('tr th').each(function(index){     if($('tr td').eq(index).attr('class') != ''){         // get the class of the td         var tdClass = $('tr td').eq(index).attr('class');         // add it to this th         $(this).addClass(tdClass );     } }); 

Fiddle

If you want to use the catch() of the Observable you need to use Observable.throw() method before delegating the error response to a method

import { Injectable } from '@angular/core';_x000D_

import { Observable } from 'rxjs/Observable';_x000D_
import 'rxjs/add/operator/map';_x000D_

_x000D_
@Injectable()_x000D_
export class CompareNfeService {_x000D_

    return this.http.post(`${MEAT_API}compare/arquivo`, order,_x000D_
        new ResponseOptions({_x000D_

_x000D_
  errorHandler(error: any): void {_x000D_
    console.log(error)_x000D_
  }_x000D_
}

Using Observable.throw() worked for me

Woo-hoo! It works with some hack!

According to this comment you need to:

1. Manually edit Microsoft.CSharp.DesignTime.targets located in C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\Microsoft\VisualStudio\Managed (for VS Community edition, modify path for other editions), append ClassDesigner value to ProjectCapability (right pane):

2. Restart VS.

3. Manually create text file, say MyClasses.cd with following content: <?xml version="1.0" encoding="utf-8"?> <ClassDiagram MajorVersion="1" MinorVersion="1"> <Font Name="Segoe UI" Size="9" /> </ClassDiagram>

Bingo. Now you may open this file in VS. You will see error message "Object reference not set to an instance of object" once after VS starts, but diagram works.

You can use this code, this code is for AES-256-CBC or you can use it for other AES encryption. Key length error mainly comes in 256-bit encryption.

This error comes due to the encoding or charset name we pass in the SecretKeySpec. Suppose, in my case, I have a key length of 44, but I am not able to encrypt my text using this long key; Java throws me an error of invalid key length. Therefore I pass my key as a BASE64 in the function, and it converts my 44 length key in the 32 bytes, which is must for the 256-bit encryption.

import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;
import java.security.MessageDigest;
import java.security.Security;
import java.util.Base64;

public class Encrypt {

    static byte [] arr = {1,2,3,4,5,6,7,8,9};

    // static byte [] arr = new byte[16];

      public static void main(String...args) {
        try {
         //   System.out.println(Cipher.getMaxAllowedKeyLength("AES"));
            Base64.Decoder decoder = Base64.getDecoder();
            // static byte [] arr = new byte[16];
            Security.setProperty("crypto.policy", "unlimited");
            String key = "Your key";
       //     System.out.println("-------" + key);

            String value = "Hey, i am adnan";
            String IV = "0123456789abcdef";
       //     System.out.println(value);
            // log.info(value);
          IvParameterSpec iv = new IvParameterSpec(IV.getBytes());
            //    IvParameterSpec iv = new IvParameterSpec(arr);

        //    System.out.println(key);
            SecretKeySpec skeySpec = new SecretKeySpec(decoder.decode(key), "AES");
         //   System.out.println(skeySpec);
            Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
        //    System.out.println("ddddddddd"+IV);
            cipher.init(Cipher.ENCRYPT_MODE, skeySpec, iv);
       //     System.out.println(cipher.getIV());

            byte[] encrypted = cipher.doFinal(value.getBytes());
            String encryptedString = Base64.getEncoder().encodeToString(encrypted);

            System.out.println("encrypted string,,,,,,,,,,,,,,,,,,,: " + encryptedString);
            // vars.put("input-1",encryptedString);
            //  log.info("beanshell");
        }catch (Exception e){
            System.out.println(e.getMessage());
        }
    }
}

This builds on ntc2 and Chris Johnsen's answer. I am using this whenever I want to create a new session with a custom history-limit. I wanted a way to create sessions with limited scrollback without permanently changing my history-limit for future sessions.

tmux set-option -g history-limit 100 \; new-session -s mysessionname \; set-option -g history-limit 2000

This works whether or not there are existing sessions. After setting history-limit for the new session it resets it back to the default which for me is 2000.

I created an executable bash script that makes this a little more useful. The 1st parameter passed to the script sets the history-limit for the new session and the 2nd parameter sets its session name:

#!/bin/bash
tmux set-option -g history-limit "${1}" \; new-session -s "${2}" \; set-option -g history-limit 2000

Well, since nobody else has stepped up, I'll write the easy code to do this:

x = ms / 1000
seconds = x % 60
x /= 60
minutes = x % 60
x /= 60
hours = x % 24
x /= 24
days = x

I'm just glad you stopped at days and didn't ask for months. :)

Note that in the above, it is assumed that / represents truncating integer division. If you use this code in a language where / represents floating point division, you will need to manually truncate the results of the division as needed.

Have you start by reading the information on this on Wikipedia - Block cipher modes of operation? Then follow the reference link on Wikipedia to NIST: Recommendation for Block Cipher Modes of Operation.

JavaScript runs synchronously, so whatever you place after each() will not run until each() is complete.

Consider the following test:

var count = 0;
var array = [];

// populate an array with 1,000,000 entries
for(var i = 0; i < 1000000; i++) {
    array.push(i);
}

// use each to iterate over the array, incrementing count each time
$.each(array, function() {
    count++
});

// the alert won't get called until the 'each' is done
//      as evidenced by the value of count
alert(count);

When the alert is called, count will equal 1000000 because the alert won't run until each() is done.

It's in the standard library.

>>> from fractions import gcd
>>> gcd(20,8)
4

Source code from the inspect module in Python 2.7:

>>> print inspect.getsource(gcd)
def gcd(a, b):
    """Calculate the Greatest Common Divisor of a and b.

    Unless b==0, the result will have the same sign as b (so that when
    b is divided by it, the result comes out positive).
    """
    while b:
        a, b = b, a%b
    return a

As of Python 3.5, gcd is in the math module; the one in fractions is deprecated. Moreover, inspect.getsource no longer returns explanatory source code for either method.

I don't have code to hand, but I always liked the approach of building a 2D lookup table of size 256 * 256 chars (RFC 1978, PPP Predictor Compression Protocol). To compress a string you loop over each char and use the lookup table to get the 'predicted' next char using the current and previous char as indexes into the table. If there is a match you write a single 1 bit, otherwise write a 0, the char and update the lookup table with the current char. This approach basically maintains a dynamic (and crude) lookup table of the most probable next character in the data stream.

You can start with a zeroed lookup table, but obviosuly it works best on very short strings if it is initialised with the most likely character for each character pair, for example, for the English language. So long as the initial lookup table is the same for compression and decompression you don't need to emit it into the compressed data.

This algorithm doesn't give a brilliant compression ratio, but it is incredibly frugal with memory and CPU resources and can also work on a continuous stream of data - the decompressor maintains its own copy of the lookup table as it decompresses, thus the lookup table adjusts to the type of data being compressed.

Back in 2010 we had the same problem and i successfully employed GoogleDocs with our small Agile Development team (8 Devs in 3 Countries).

GoogleDrawing will serve in the exact same way as a physical Scrum board would, with all the upsides of full flexibilty and also the downsides of zero automation but with the big additional upside of being virtual and accessible from anywhere with an internet connection.

It also was used for the retrospective at the end of each Sprint

GoogleSpreadsheet was used for a concise list of all the tickets from our bug tracking system (Redmine, manually transfered) and also for the (manually updated, albeit with formulas to calculate the progress) burndown chart.

The combination of these different elements is actually quite powerful, as you have the full flexibility over the content and its representation and can have your team communicate via VoIP while all are looking at the same documents and can modify them in real-time.

Here an example of the docs used in a sprint (all sensitive data removed):

• Scrum board Example (GoogleDrawing)
• Retrospective Example (GoogleDrawing)
• Burndown Chart Example (GoogleSheet, formulas to automate calculation)
• Ticket list from Bugtracker (GoogleSheet)

As mentioned before, the only downside is the fact that you have to invest some time to maintain and prepare the data for each sprint, but for us that was hugely outweighed by the flexibility and accessibility that the Team of GoogleDocs + VoIP gave us.

There is an much easier way to do this.

Just open the file inspector and select a "global tint".

You can also set an app’s tint color in Interface Builder. The Global Tint menu in the Interface Builder Document section of the File inspector lets you open the Colors window or choose a specific color.

Try with cURL request for cross-domain.

If you are working through third party APIs or getting data through CROSS-DOMAIN, it is always recommended to use cURL script (server side) which is more secure.

I always prefer cURL script.

Using CliWrap:

var result = await Cli.Wrap("foobar.bat").ExecuteBufferedAsync();

var exitCode = result.ExitCode;
var stdOut = result.StandardOutput;

Late to the party, but might be of interest...

I find a combination of labs and guides specification useful in many cases:

You want nothing but a grid and a background:

ggplot(diamonds, mapping = aes(x = clarity)) + 
  geom_bar(aes(fill = cut)) + 
  labs(x = NULL, y = NULL) + 
  guides(x = "none", y = "none")

You want to only suppress the tick-mark label of one or both axes:

ggplot(diamonds, mapping = aes(x = clarity)) + 
  geom_bar(aes(fill = cut)) + 
  guides(x = "none", y = "none")

I think the easiest from a logical and efficiency point of view is using the queryset's exists() function, documented here:

https://docs.djangoproject.com/en/stable/ref/models/querysets/#django.db.models.query.QuerySet.exists

So in your example above I would simply write:

if User.objects.filter(email = cleaned_info['username']).exists():
    # at least one object satisfying query exists
else:
    # no object satisfying query exists

The git solution for such scenarios is setting SKIP-WORKTREE BIT. Run only the following command:

git update-index --skip-worktree .classpath .gitignore

It is used when you want git to ignore changes of files that are already managed by git and exist on the index. This is a common use case for config files.

Running git rm --cached doesn't work for the scenario mentioned in the question. If I simplify the question, it says:

How to have .classpath and .project on the repo while each one can change it locally and git ignores this change?

As I commented under the accepted answer, the drawback of git rm --cached is that it causes a change in the index, so you need to commit the change and then push it to the remote repository. As a result, .classpath and .project won't be available on the repo while the PO wants them to be there so anyone that clones the repo for the first time, they can use it.

What is SKIP-WORKTREE BIT?

Based on git documentaion:

Skip-worktree bit can be defined in one (long) sentence: When reading an entry, if it is marked as skip-worktree, then Git pretends its working directory version is up to date and read the index version instead. Although this bit looks similar to assume-unchanged bit, its goal is different from assume-unchanged bit’s. Skip-worktree also takes precedence over assume-unchanged bit when both are set.

More details is available here.

From the documentation,

Positioning your Toast

A standard toast notification appears near the bottom of the screen, centered horizontally. You can change this position with the setGravity(int, int, int) method. This accepts three parameters: a Gravity constant, an x-position offset, and a y-position offset.

For example, if you decide that the toast should appear in the top-left corner, you can set the gravity like this:

toast.setGravity(Gravity.TOP|Gravity.LEFT, 0, 0);

If you want to nudge the position to the right, increase the value of the second parameter. To nudge it down, increase the value of the last parameter.

In PowerShell, I like to use:

robocopy src dest | Out-Null

It avoids having to remember all the command line switches.

If you can't get to your php.ini file for some reason, disable errors to stdout (display_errors) in a .htaccess file in any directory by adding the following line:

php_flag display_errors off

additionally, you can add error logging to a file:

php_flag log_errors on

Use Access's VBA function Replace(text, find, replacement):

Dim result As String

result = Replace("Some sentence containing Avenue in it.", "Avenue", "Ave")

You can add other repo first as a remote to your current repo:

git remote add other_name PATH_TO_OTHER_REPO

then fetch brach from that remote:

git fetch other_name branch_name:branch_name

this creates that branch as a new branch in your current repo, then you can diff that branch with any of your branches, for example, to compare current branch against new branch(branch_name):

git diff branch_name

This worked for me, curly braces are not required.

UPDATE: TensorFlow supports Python 3.6 on Windows since version 1.2.0 (see the release notes)

TensorFlow only supports Python 3.5 64-bit as of now. Support for Python 3.6 is a work in progress and you can track it here as well as chime in the discussion.

The only alternative to use Python 3.6 with TensorFlow on Windows currently is building TF from source.

If you don't want to uninstall your Anaconda distribution for Python 3.6 and install a previous release you can create a conda environment for Python=3.5 as in: conda create --name tensorflow python=3.5 activate tensorflow pip install tensorflow-gpu

If you want to import a specific function or class from a module, you can do this:

import sys
importlib.reload(sys.modules['my_module'])

My simple, simple, simple approach! =D

Code

string_to_test = "The criminals stole $1,000,000 in jewels."
chars_to_check = ["$", ",", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9"]
for char in chars_to_check:
    if char in string_to_test:
        print("Char \"" + char + "\" detected!")

Output

Char "$" detected!
Char "," detected!
Char "0" detected!
Char "1" detected!

Thanks!

Many people will suggest you use MERGE, but I caution you against it. By default, it doesn't protect you from concurrency and race conditions any more than multiple statements, but it does introduce other dangers:

http://www.mssqltips.com/sqlservertip/3074/use-caution-with-sql-servers-merge-statement/

Even with this "simpler" syntax available, I still prefer this approach (error handling omitted for brevity):

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
UPDATE dbo.table SET ... WHERE PK = @PK;
IF @@ROWCOUNT = 0
BEGIN
  INSERT dbo.table(PK, ...) SELECT @PK, ...;
END
COMMIT TRANSACTION;

A lot of folks will suggest this way:

SET TRANSACTION ISOLATION LEVEL SERIALIZABLE;
BEGIN TRANSACTION;
IF EXISTS (SELECT 1 FROM dbo.table WHERE PK = @PK)
BEGIN
  UPDATE ...
END
ELSE
BEGIN
  INSERT ...
END
COMMIT TRANSACTION;

But all this accomplishes is ensuring you may need to read the table twice to locate the row(s) to be updated. In the first sample, you will only ever need to locate the row(s) once. (In both cases, if no rows are found from the initial read, an insert occurs.)

Others will suggest this way:

BEGIN TRY
  INSERT ...
END TRY
BEGIN CATCH
  IF ERROR_NUMBER() = 2627
    UPDATE ...
END CATCH

However, this is problematic if for no other reason than letting SQL Server catch exceptions that you could have prevented in the first place is much more expensive, except in the rare scenario where almost every insert fails. I prove as much here:

• http://www.mssqltips.com/sqlservertip/2632/checking-for-potential-constraint-violations-before-entering-sql-server-try-and-catch-logic/
• http://www.sqlperformance.com/2012/08/t-sql-queries/error-handling

Not sure what you think you gain by having a single statement; I don't think you gain anything. MERGE is a single statement but it still has to really perform multiple operations anyway - even though it makes you think it doesn't.

If you are lazy, and have a lot of RAM, create a sieve of Eratosthenes which is practically a giant array from which you kicked all numbers that are not prime. From then on every prime "probability" test will be super quick. The upper limit for this solution for fast results is the amount of you RAM. The upper limit for this solution for superslow results is your hard disk's capacity.

exec has memory limitation of buffer size of 512k. In this case it is better to use spawn. With spawn one has access to stdout of executed command at run time

var spawn = require('child_process').spawn;
var prc = spawn('java',  ['-jar', '-Xmx512M', '-Dfile.encoding=utf8', 'script/importlistings.jar']);

//noinspection JSUnresolvedFunction
prc.stdout.setEncoding('utf8');
prc.stdout.on('data', function (data) {
    var str = data.toString()
    var lines = str.split(/(\r?\n)/g);
    console.log(lines.join(""));
});

prc.on('close', function (code) {
    console.log('process exit code ' + code);
});

If available you can probe the current user account with posix_geteuid and then get the user name with posix_getpwuid.

$username = posix_getpwuid(posix_geteuid())['name'];

If you are running in safe mode however (which is often the case when exec is disabled), then it's unlikely that your PHP process is running under anything but the default www-data or apache account.

even cleaner:

    public static bool TryCast<T>(ref T t, object o)
    {
        if (!(o is T))
        {
            return false;
        }

        t = (T)o;
        return true;
    }

Use the context-parameter

$("#testdiv",parent.document)

But if you really use a popup, you need to access opener instead of parent

$("#testdiv",opener.document)

If it echoing out to a browser, you should use CSS. This would require also having the comment wrapped in an HTML tag. Something like:

echo '<p style="color: red; text-align: center">
      Request has been sent. Please wait for my reply!
      </p>';

Variables can point to anywhere they want.. An error will be thrown if you do the following:

a = "dog"
print a                   #dog
a[1] = "g"                #ERROR!!!!!! STRINGS ARE IMMUTABLE

I think this will probably answer your question. Here's what I wrote there:

Here's a very general answer. Say the camera's at (Xc, Yc, Zc) and the point you want to project is P = (X, Y, Z). The distance from the camera to the 2D plane onto which you are projecting is F (so the equation of the plane is Z-Zc=F). The 2D coordinates of P projected onto the plane are (X', Y').

Then, very simply:

X' = ((X - Xc) * (F/Z)) + Xc

Y' = ((Y - Yc) * (F/Z)) + Yc

If your camera is the origin, then this simplifies to:

X' = X * (F/Z)

Y' = Y * (F/Z)

Thanks! to all above answers. I hope you have a .p12 file. Now, open terminal write following command. Set terminal to the path where you have put .12 file.

$ openssl pkcs12 -in yourCertifcate.p12 -out pemAPNSCert.pem -nodes
Enter Import Password: <Just enter your certificate password>
MAC verified OK

Now your .pem file is generated.

Verify .pem file First, open the .pem in a text editor to view its content. The certificate content should be in format as shown below. Make sure the pem file contains both Certificate content(from BEGIN CERTIFICATE to END CERTIFICATE) as well as Certificate Private Key (from BEGIN PRIVATE KEY to END PRIVATE KEY) :

> Bag Attributes
>     friendlyName: Apple Push Services:<Bundle ID>
>     localKeyID: <> subject=<>
> -----BEGIN CERTIFICATE-----
> 
> <Certificate Content>
> 
> -----END CERTIFICATE----- Bag Attributes
>     friendlyName: <>
>     localKeyID: <> Key Attributes: <No Attributes>
> -----BEGIN PRIVATE KEY-----
> 
> <Certificate Private Key>
> 
> -----END PRIVATE KEY-----

Also, you check the validity of the certificate by going to SSLShopper Certificate Decoder and paste the Certificate Content (from BEGIN CERTIFICATE to END CERTIFICATE) to get all the info about the certificate as shown below:

You can also sometimes get this error if you try to decrypt a secret while su-ed to a different user on a system with GPG 2.x installed. This bug has been reported against RHEL 6 but there is no fix available; apparently this is due to some design decisions in GPG 2.x. One workaround suggested in the bug report is to run the decryption inside of a tmux or screen session. More reading here.

After updating the manifest file, instead of building your project, go to command line and reach the path ...bld\Debug\platforms\android. Run the command "ant release". Your new release.apk file will have a new version code.

use .empty()

 $('select').empty().append('whatever');

you can also use .html() but note

When .html() is used to set an element's content, any content that was in that element is completely replaced by the new content. Consider the following HTML:

alternative: --- If you want only option elements to-be-remove, use .remove()

$('select option').remove();

This is an iterable function without yield. It make use of the iter function and a closure which keeps it's state in a mutable (list) in the enclosing scope for python 2.

def count(low, high):
    counter = [0]
    def tmp():
        val = low + counter[0]
        if val < high:
            counter[0] += 1
            return val
        return None
    return iter(tmp, None)

For Python 3, closure state is kept in an immutable in the enclosing scope and nonlocal is used in local scope to update the state variable.

def count(low, high):
    counter = 0
    def tmp():
        nonlocal counter
        val = low + counter
        if val < high:
            counter += 1
            return val
        return None
    return iter(tmp, None)

    print(i)

Try to create remote origin first, maybe is missing because you change name of the remote repo

git remote add origin URL_TO_YOUR_REPO

Microsoft recently modified the reflection API rendering most of these answers obsolete. The following should work on modern platforms (including Xamarin.Forms and UWP):

obj.GetType().GetTypeInfo().GetDeclaredMethod("MethodName").Invoke(obj, yourArgsHere);

Or as an extension method:

public static object InvokeMethod<T>(this T obj, string methodName, params object[] args)
{
    var type = typeof(T);
    var method = type.GetTypeInfo().GetDeclaredMethod(methodName);
    return method.Invoke(obj, args);
}

Note:

• If the desired method is in a superclass of obj the T generic must be explicitly set to the type of the superclass.

• If the method is asynchronous you can use await (Task) obj.InvokeMethod(…).

Here's a simpler(short) solution to check for empty variables. This function checks if a variable is empty. The variable provided may contain mixed values (null, undefined, array, object, string, integer, function).

function empty(mixed_var) {
 if (!mixed_var || mixed_var == '0') {
  return true;
 }
 if (typeof mixed_var == 'object') {
  for (var k in mixed_var) {
   return false;
  }
  return true;
 }
 return false;
}

//   example 1: empty(null);
//   returns 1: true

//   example 2: empty(undefined);
//   returns 2: true

//   example 3: empty([]);
//   returns 3: true

//   example 4: empty({});
//   returns 4: true

//   example 5: empty(0);
//   returns 5: true

//   example 6: empty('0');
//   returns 6: true

//   example 7: empty(function(){});
//   returns 7: false

Use atoi() from <stdlib.h>

http://linux.die.net/man/3/atoi

Or, write your own atoi() function which will convert char* to int

int a2i(const char *s)
{
  int sign=1;
  if(*s == '-'){
    sign = -1;
    s++;
  }
  int num=0;
  while(*s){
    num=((*s)-'0')+num*10;
    s++;   
  }
  return num*sign;
}

in MYSQL 5.7, max_allowed_packet is at most 1G. if you want to set it to 4G, it would failed without error and warning.

<form class="d-flex">

</form>

Better yet, use what's built into Bootstrap:

    <div class="input-group">
      <div class="input-group-prepend">
        <label for="myInput" class="input-group-text">Default</label>

Code for adding fragment

public Fragment getItem(int position) {

    switch (position){
        case 0:

        default:
            break;
    }

    return null;
}

Create an xml file for each fragment say for Fragment1, use fragment_one.xml as layout file, use the below code in Fragment1 java file.

public class Fragment1 extends Fragment {

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.fragment_one, container, false);

        return view;

    }
}

public partial class Class

The answer provided by Joe Stefanelli is already correct.

SELECT name FROM (SELECT name FROM agentinformation) as a  

We need to make an alias of the subquery because a query needs a table object which we will get from making an alias for the subquery. Conceptually, the subquery results are substituted into the outer query. As we need a table object in the outer query, we need to make an alias of the inner query.

Statements that include a subquery usually take one of these forms:

• WHERE expression [NOT] IN (subquery)
• WHERE expression comparison_operator [ANY | ALL] (subquery)
• WHERE [NOT] EXISTS (subquery)

Check for more subquery rules and subquery types.

More examples of Nested Subqueries.

1. IN / NOT IN – This operator takes the output of the inner query after the inner query gets executed which can be zero or more values and sends it to the outer query. The outer query then fetches all the matching [IN operator] or non matching [NOT IN operator] rows.

2. ANY – [>ANY or ANY operator takes the list of values produced by the inner query and fetches all the values which are greater than the minimum value of the list. The

e.g. >ANY(100,200,300), the ANY operator will fetch all the values greater than 100.

3. ALL – [>ALL or ALL operator takes the list of values produced by the inner query and fetches all the values which are greater than the maximum of the list. The

e.g. >ALL(100,200,300), the ALL operator will fetch all the values greater than 300.

4. EXISTS – The EXISTS keyword produces a Boolean value [TRUE/FALSE]. This EXISTS checks the existence of the rows returned by the sub query.

If you don't want to register a listener on every component,
you could add your own KeyEventDispatcher to the KeyboardFocusManager:

public class MyFrame extends JFrame {    
    private class MyDispatcher implements KeyEventDispatcher {
        @Override
        public boolean dispatchKeyEvent(KeyEvent e) {
            if (e.getID() == KeyEvent.KEY_PRESSED) {
                System.out.println("tester");
            } else if (e.getID() == KeyEvent.KEY_RELEASED) {
                System.out.println("2test2");
            } else if (e.getID() == KeyEvent.KEY_TYPED) {
                System.out.println("3test3");
            }
            return false;
        }
    }
    public MyFrame() {
        add(new JTextField());
        System.out.println("test");
        KeyboardFocusManager manager = KeyboardFocusManager.getCurrentKeyboardFocusManager();
        manager.addKeyEventDispatcher(new MyDispatcher());
    }

    public static void main(String[] args) {
        MyFrame f = new MyFrame();
        f.pack();
        f.setVisible(true);
    }
}

This should work in the way that you describe. What error are you getting? If you could pastebin your code that would help.

You can change the height of a form by doing the following where you want to change the size (substitute '10' for your size):

this.Height = 10;

This can be done with the width as well:

this.Width = 10;

This can all be done easily with linq. This will find any types that are a subclass of generic base class GenericBaseType.

    IEnumerable<Type> allTypes = Assembly.GetExecutingAssembly().GetTypes();

    IEnumerable<Type> mySubclasses = allTypes.Where(t => t.BaseType != null 
                                                            && t.BaseType.IsGenericType
                                                            && t.BaseType.GetGenericTypeDefinition() == typeof(GenericBaseType<,>));

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

The simplest approach would be to create a method that returns a DateInterval from the DateTime::diff of the relative time in $seconds from the current time $now which you can then chain and format. For example:-

public function toDateInterval($seconds) {
    return date_create('@' . (($now = time()) + $seconds))->diff(date_create('@' . $now));
}

Now chain your method call to DateInterval::format

echo $this->toDateInterval(1640467)->format('%a days %h hours %i minutes'));

Result:

18 days 23 hours 41 minutes

Just complementing Hovercraft Full Of Eels's solution:

I reworked his code, tweaked it a bit, adding a grid, axis labels and now the Y-axis goes from the minimum value present up to the maximum value. I planned on adding a couple of getters/setters but I didn't need them, you can add them if you want.

Intel HD Graphics is usually the on-CPU graphics chip in newer Core i3/i5/i7 processors.

As far as I know it doesn't support CUDA (which is a proprietary NVidia technology), but OpenCL is supported by NVidia, ATi and Intel.

As hadley mentioned there are more effective ways of communicating your message than labels in stacked bar charts. In fact, stacked charts aren't very effective as the bars (each Category) doesn't share an axis so comparison is hard.

It's almost always better to use two graphs in these instances, sharing a common axis. In your example I'm assuming that you want to show overall total and then the proportions each Category contributed in a given year.

library(grid)
library(gridExtra)
library(plyr)

# create a new column with proportions
prop <- function(x) x/sum(x)
Data <- ddply(Data,"Year",transform,Share=prop(Frequency))

# create the component graphics
totals <- ggplot(Data,aes(Year,Frequency)) + geom_bar(fill="darkseagreen",stat="identity") + 
  xlab("") + labs(title = "Frequency totals in given Year")
proportion <- ggplot(Data, aes(x=Year,y=Share, group=Category, colour=Category)) 
+ geom_line() + scale_y_continuous(label=percent_format())+ theme(legend.position = "bottom") + 
  labs(title = "Proportion of total Frequency accounted by each Category in given Year")

# bring them together
grid.arrange(totals,proportion)

This will give you a 2 panel display like this:

If you want to add Frequency values a table is the best format.

I depends on what is the regexp language you use, but informally, it would be:

[:alpha:][:alpha:][:digit:][:digit:][:digit:][:digit:][:digit:][:digit:]

where [:alpha:] = [a-zA-Z] and [:digit:] = [0-9]

If you use a regexp language that allows finite repetitions, that would look like:

[:alpha:]{2}[:digit:]{6}

The correct syntax depends on the particular language you're using, but that is the idea.

You can get around that limit by using subst if you need to.

As of SQL Server 2012 you no longer have to go through the hassle of deleting the bin file (which causes other side effects). You should be able to press the delete key within the MRU list of the Server Name dropdown in the Connect to Server dialog. This is documented in this Connect item and this blog post.

Note that if you have multiple entries for a single server name (e.g. one with Windows and one with SQL Auth), you won't be able to tell which one you're deleting.

That task should be done by the next layer up in your software stack. SQL is a data repository, not a presentation system

You can do it with

CONVERT(VARCHAR(10), fmdate(), 101)

But you shouldn't

Based on Xavier's answer, I wrote a Google chrome extension NuTake to add links to the Nuget.org package pages.

For static files like pdfs, Word docs, etc. just use Express's static function in your config:

// Express config
var app = express().configure(function () {
    this.use('/public', express.static('public')); // <-- This right here
});

And then just put all your files inside that 'public' folder, for example:

/public/docs/my_word_doc.docx

And then a regular old link will allow the user to download it:

<a href="public/docs/my_word_doc.docx">My Word Doc</a>

ON DELETE CASCADE
It specifies that the child data is deleted when the parent data is deleted.

CREATE TABLE products
( product_id INT PRIMARY KEY,
  product_name VARCHAR(50) NOT NULL,
  category VARCHAR(25)
);

CREATE TABLE inventory
( inventory_id INT PRIMARY KEY,
  product_id INT NOT NULL,
  quantity INT,
  min_level INT,
  max_level INT,
  CONSTRAINT fk_inv_product_id
    FOREIGN KEY (product_id)
    REFERENCES products (product_id)
    ON DELETE CASCADE
);

For this foreign key, we have specified the ON DELETE CASCADE clause which tells SQL Server to delete the corresponding records in the child table when the data in the parent table is deleted. So in this example, if a product_id value is deleted from the products table, the corresponding records in the inventory table that use this product_id will also be deleted.

Clean solution while staying with the nio API:

Files.isDirectory(path)
Files.isRegularFile(path)

Note that :

typeof $(this) is JQuery object.

and

typeof $(this)[0] is HTMLElement object

then : if you want to apply .val() on HTMLElement , you can add this extension .

HTMLElement.prototype.val=function(v){
   if(typeof v!=='undefined'){this.value=v;return this;}
   else{return this.value}
}

Then :

document.getElementById('myDiv').val() ==== $('#myDiv').val()

And

 document.getElementById('myDiv').val('newVal') ==== $('#myDiv').val('newVal')

????? INVERSE :

Conversely? if you want to add value property to jQuery object , follow those steps :

1. Download the full source code (not minified) i.e: example http://code.jquery.com/jquery-1.11.1.js .

2. Insert Line after L96 , add this code value:"" to init this new prop

3. Search on jQuery.fn.init , it will be almost Line 2747

4. Now , assign a value to value prop : (Before return statment add this.value=jQuery(selector).val())

Enjoy now : $('#myDiv').value

The link you gave seems to be attempting something different to the test you are trying to avoid repeating.

if (a == null || a=='')

tests if the string is an empty string or null. The article you linked to tests if the string consists entirely of whitespace (or is empty).

The test you described can be replaced by:

if (!a)

Because in javascript, an empty string, and null, both evaluate to false in a boolean context.

Remove the function and check the output of:

var_dump(function_exists('parseDate'));

In which case, change the name of the function.

If you get false, you're including the file with that function twice, replace :

include

by

include_once

And replace :

require

by

require_once

Simply add a -h after adding your credentials using a -u -p, and it will run with elevated privileges.

It is possible. Here is some step by step:

In $PROJECT_DIR/jni/Application.mk:

APP_STL                 := stlport_static

I tried using stlport_shared, but no luck. Same with libstdc++.

In $PROJECT_DIR/jni/Android.mk:

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := hello-jni
LOCAL_SRC_FILES := hello-jni.cpp
LOCAL_LDLIBS    := -llog

include $(BUILD_SHARED_LIBRARY)

Nothing special here, but make sure your files are .cpp.

In $PROJECT_DIR/jni/hello-jni.cpp:

#include <string.h>
#include <jni.h>
#include <android/log.h>

#include <iostream>
#include <vector>


#define  LOG_TAG    "hellojni"
#define  LOGI(...)  __android_log_print(ANDROID_LOG_INFO,LOG_TAG,__VA_ARGS__)

I created a method fixUntrustCertificate(), so when I am dealing with a domain that is not in trusted CAs you can invoke the method before the request. This code will gonna work after java1.4. This method applies for all hosts:

public void fixUntrustCertificate() throws KeyManagementException, NoSuchAlgorithmException{


        TrustManager[] trustAllCerts = new TrustManager[]{
            new X509TrustManager() {
                public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                    return null;
                }

                public void checkClientTrusted(X509Certificate[] certs, String authType) {
                }

                public void checkServerTrusted(X509Certificate[] certs, String authType) {
                }

            }
        };

        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, trustAllCerts, new java.security.SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

        HostnameVerifier allHostsValid = new HostnameVerifier() {
            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        };

        // set the  allTrusting verifier
        HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);
}

Try

return value.replaceAll("[^A-Za-z0-9]", "");

or

return value.replaceAll("[\\W]|_", "");

I just used getLocaleString() function for my application. It should adapt the timeformat common to the locale, so no +0200 etc. Ofcourse, there will be less possibility for controlling the width of your string then.

var str = (new Date(1400167800)).toLocaleString();

another scheme showing __proto__, prototype and constructor relations:

I tweaked your code a bit and made it more robust. In terms of progressive enhancement it's probaly better to have all the fade-in-out logic in JavaScript. In the example of myfunksyde any user without JavaScript sees nothing because of the opacity: 0;.

    $(window).on("load",function() {
    function fade() {
        var animation_height = $(window).innerHeight() * 0.25;
        var ratio = Math.round( (1 / animation_height) * 10000 ) / 10000;

        $('.fade').each(function() {

            var objectTop = $(this).offset().top;
            var windowBottom = $(window).scrollTop() + $(window).innerHeight();

            if ( objectTop < windowBottom ) {
                if ( objectTop < windowBottom - animation_height ) {
                    $(this).html( 'fully visible' );
                    $(this).css( {
                        transition: 'opacity 0.1s linear',
                        opacity: 1
                    } );

                } else {
                    $(this).html( 'fading in/out' );
                    $(this).css( {
                        transition: 'opacity 0.25s linear',
                        opacity: (windowBottom - objectTop) * ratio
                    } );
                }
            } else {
                $(this).html( 'not visible' );
                $(this).css( 'opacity', 0 );
            }
        });
    }
    $('.fade').css( 'opacity', 0 );
    fade();
    $(window).scroll(function() {fade();});
});

While correct that this will work:

TimeSpan time = TimeSpan.Parse("07:35");

And if you are using it for validation...

TimeSpan time;
if (!TimeSpan.TryParse("07:35", out time))
{
    // handle validation error
}

Consider that TimeSpan is primarily intended to work with elapsed time, rather than time-of-day. It will accept values larger than 24 hours, and will accept negative values also.

If you need to validate that the input string is a valid time-of-day (>= 00:00 and < 24:00), then you should consider this instead:

DateTime dt;
if (!DateTime.TryParseExact("07:35", "HH:mm", CultureInfo.InvariantCulture, 
                                              DateTimeStyles.None, out dt))
{
    // handle validation error
}
TimeSpan time = dt.TimeOfDay;

As an added benefit, this will also parse 12-hour formatted times when an AM or PM is included, as long as you provide the appropriate format string, such as "h:mm tt".

CSS rules are inherited by default - hence the "cascading" name. To get what you want you need to use !important:

form div
{
    font-size: 12px;
    font-weight: bold;
}

div.content
{
    // any rule you want here, followed by !important
}

Use JavaScript setInterval() method to redirect page after some specified time. The following script will redirect page after 5 seconds.

var count = 5;
setInterval(function(){
    count--;
    document.getElementById('countDown').innerHTML = count;
    if (count == 0) {
        window.location = 'https://www.google.com'; 
    }
},1000);

Example script and live demo can be found from here - Redirect page after delay using JavaScript

From a background script you can listen to the chrome.tabs.onUpdated event and check the property changeInfo.status on the callback. It can be loading or complete. If it is complete, do the action.

Example:

chrome.tabs.onUpdated.addListener( function (tabId, changeInfo, tab) {
  if (changeInfo.status == 'complete') {

    // do your things

  }
})

Because this will probably trigger on every tab completion, you can also check if the tab is active on its homonymous attribute, like this:

chrome.tabs.onUpdated.addListener( function (tabId, changeInfo, tab) {
  if (changeInfo.status == 'complete' && tab.active) {

    // do your things

  }
})

If you use Windows, there some shortcuts, while devtools are opened:

Pressing Ctrl+Shift+D will dock all devtools to left, right, bottom in turn.

Press Ctrl+Shift+F if your JS console disappeared, and you want it docked back to bottom within dev tools.

I just ran into this.

If you're not seeing curl in the list (see ibaralf's screenshot), then you may have out-of-date cygwin sources. In one of the screens in cygwin's setup.exe wizard, you have the option to "Install from Internet" or "Install from Local Directory". If you have the "Install from Local Directory" option enabled, then you may not see curl in the list. Switch to "Install from Internet" and select a mirror and then you should see curl.

TCP :

Transmission Control Protocol is a connection-oriented protocol, which means that it requires handshaking to set up end-to-end communications. Once a connection is set up, user data may be sent bi-directionally over the connection.

Reliable – Strictly only at transport layer, TCP manages message acknowledgment, retransmission and timeout. Multiple attempts to deliver the message are made. If it gets lost along the way, the server will re-request the lost part. In TCP, there's either no missing data, or, in case of multiple timeouts, the connection is dropped. (This reliability however does not cover application layer, at which a separate acknowledgement flow control is still necessary)

Ordered – If two messages are sent over a connection in sequence, the first message will reach the receiving application first. When data segments arrive in the wrong order, TCP buffers delay the out-of-order data until all data can be properly re-ordered and delivered to the application.

Heavyweight – TCP requires three packets to set up a socket connection, before any user data can be sent. TCP handles reliability and congestion control. Streaming – Data is read as a byte stream, no distinguishing indications are transmitted to signal message (segment) boundaries.

Applications of TCP

World Wide Web, email, remote administration, and file transfer rely on TCP.

UDP :

User Datagram Protocol is a simpler message-based connectionless protocol. Connectionless protocols do not set up a dedicated end-to-end connection. Communication is achieved by transmitting information in one direction from source to destination without verifying the readiness or state of the receiver.

Unreliable – When a UDP message is sent, it cannot be known if it will reach its destination; it could get lost along the way. There is no concept of acknowledgment, retransmission, or timeout.

Not ordered – If two messages are sent to the same recipient, the order in which they arrive cannot be predicted.

Lightweight – There is no ordering of messages, no tracking connections, etc. It is a small transport layer designed on top of IP.

Datagrams – Packets are sent individually and are checked for integrity only if they arrive. Packets have definite boundaries which are honored upon receipt, meaning a read operation at the receiver socket will yield an entire message as it was originally sent. No congestion control – UDP itself does not avoid congestion. Congestion control measures must be implemented at the application level.

Broadcasts – being connectionless, UDP can broadcast - sent packets can be addressed to be receivable by all devices on the subnet.

Multicast – a multicast mode of operation is supported whereby a single datagram packet can be automatically routed without duplication to very large numbers of subscribers.

Applications of UDP

Numerous key Internet applications use UDP, including: the Domain Name System (DNS), where queries must be fast and only consist of a single request followed by a single reply packet, the Simple Network Management Protocol (SNMP), the Routing Information Protocol (RIP) and the Dynamic Host Configuration Protocol (DHCP).

Voice and video traffic is generally transmitted using UDP. Real-time video and audio streaming protocols are designed to handle occasional lost packets, so only slight degradation in quality occurs, rather than large delays if lost packets were retransmitted. Because both TCP and UDP run over the same network, many businesses are finding that a recent increase in UDP traffic from these real-time applications is hindering the performance of applications using TCP, such as point of sale, accounting, and database systems. When TCP detects packet loss, it will throttle back its data rate usage. Since both real-time and business applications are important to businesses, developing quality of service solutions is seen as crucial by some.

Some VPN systems such as OpenVPN may use UDP while implementing reliable connections and error checking at the application level.

If all you need to do is count how many values fall in each category, then this is a classic statistics question and can be very elegantly solved with a "histogram."

In Excel, you use the Data Analysis Add-In (if you don't have it already, refer to the link below). Once you understand histograms, you can segregate your data into buckets - called "bins" - very quickly, easily adjust your bins, and automatically chart the data.

It's three simple steps: 1) Put your data in one column 2) Create a column for your bins (10, 20, 30, etc.) 3) Select Data --> Data Analysis --> Histogram and follow the instructions for selecting the data range and bins (you can put the results into a new worksheet and Chart the results from this same menu)

http://office.microsoft.com/en-us/excel-help/create-a-histogram-HP001098364.aspx

In case you want to get the row count in the middle of a chained operation, you can use:

df.pipe(len)

Example:

row_count = (
      pd.DataFrame(np.random.rand(3,4))
      .reset_index()
      .pipe(len)
)

This can be useful if you don't want to put a long statement inside a len() function.

You could use __len__() instead but __len__() looks a bit weird.

sqlall just prints the SQL, it doesn't execute it. syncdb will create tables that aren't already created, but it won't modify existing tables.

Install autoenv either by

$ pip install autoenv

(or)

$ brew install autoenv

And then create .env file in your virtualenv project folder

$ echo "source bin/activate" > .env

Now everything works fine.

Strong typing probably means that variables have a well-defined type and that there are strict rules about combining variables of different types in expressions. For example, if A is an integer and B is a float, then the strict rule about A+B might be that A is cast to a float and the result returned as a float. If A is an integer and B is a string, then the strict rule might be that A+B is not valid.

Static typing probably means that types are assigned at compile time (or its equivalent for non-compiled languages) and cannot change during program execution.

Note that these classifications are not mutually exclusive, indeed I would expect them to occur together frequently. Many strongly-typed languages are also statically-typed.

And note that when I use the word 'probably' it is because there are no universally accepted definitions of these terms. As you will already have seen from the answers so far.

Many excellent answers so far, and they do answer the question...But, if you don't want to have to deal with disabling graphics driver's settings, or creating new keyboard mappings, or are developing through a remote session (RDP) or within a VM that intercepts your keystrokes, good-old keyboard navigation still works. Just do Alt-N to bring up the Navigate menu and then hit the B key.

Please note that you don't hit all keys at the same time. So:

Alt-N wait B

This is what I use all the time, for exactly the case that the OP asked about. Also, this will probably hold through any IntelliJ updates.

A complete unfailing solution to thread scheduling, which should yield exactly the same times per each test, is to compile your program to be OS independent and boot up your computer so as to run the program in an OS-free environment. Yet, this is largely impractical and would be difficult at best.

A good substitute to going OS-free is just to set the affinity of the current thread to 1 core and the priority to the highest. This alternative should provide consistent-enough results.

Also you should turn off optimizations which would interfere with debugging, which for g++ or gcc means adding -Og to the command line, to prevent the code being tested from being optimized out. The -O0 flag should not be used because it introduces extra unneeded overhead which would be included in the timing results, thus skewing the timed speed of the code.

On the contrary, both assuming that you use -Ofast (or, at the very least, -O3) on the final production build and ignoring the issue of "dead" code elimination, -Og performs very few optimizations compared to -Ofast; thus -Og can misrepresent the real speed of the code in the final product.

Further, all speed tests (to some extent) perjure: in the final production product compiled with -Ofast, each snippet/section/function of code is not isolated; rather, each snippet of code continuously flows into the next, thus allowing the compiler to potential join, merge, and optimize together pieces of code from all over the place.

At the same time, if you are benchmarking a snippet of code which makes heavy use of realloc(), then the snippet of code might run slower in a production product with high enough memory fragmentation. Hence, the expression "the whole is more than the sum of its parts" applies to this situation because code in the final production build might run noticeably faster or slower than the individual snippet which you are speed testing.

A partial solution that may lessen the incongruity is using -Ofast for speed testing WITH the addition of asm volatile("" :: "r"(var)) to the variables involved in the test for preventing dead code/loop elimination.

Here is an example of how to benchmark square root functions on a Windows computer.

// set USE_ASM_TO_PREVENT_ELIMINATION  to 0 to prevent `asm volatile("" :: "r"(var))`
// set USE_ASM_TO_PREVENT_ELIMINATION  to 1 to enforce `asm volatile("" :: "r"(var))`
#define USE_ASM_TO_PREVENT_ELIMINATION 1

Please note (this is very important) that if you are going to be running bigger code snippets, then you really must turn down the number of iterations to prevent your computer from freezing up.

%d is for integers use %f instead, it works for both float and double types:

double d = 1.2;
float f = 1.2f;
System.out.printf("%f %f",d,f); // prints 1.200000 1.200000

An ioctl, which means "input-output control" is a kind of device-specific system call. There are only a few system calls in Linux (300-400), which are not enough to express all the unique functions devices may have. So a driver can define an ioctl which allows a userspace application to send it orders. However, ioctls are not very flexible and tend to get a bit cluttered (dozens of "magic numbers" which just work... or not), and can also be insecure, as you pass a buffer into the kernel - bad handling can break things easily.

An alternative is the sysfs interface, where you set up a file under /sys/ and read/write that to get information from and to the driver. An example of how to set this up:

static ssize_t mydrvr_version_show(struct device *dev,
        struct device_attribute *attr, char *buf)
{
    return sprintf(buf, "%s\n", DRIVER_RELEASE);
}

static DEVICE_ATTR(version, S_IRUGO, mydrvr_version_show, NULL);

And during driver setup:

device_create_file(dev, &dev_attr_version);

You would then have a file for your device in /sys/, for example, /sys/block/myblk/version for a block driver.

Another method for heavier use is netlink, which is an IPC (inter-process communication) method to talk to your driver over a BSD socket interface. This is used, for example, by the WiFi drivers. You then communicate with it from userspace using the libnl or libnl3 libraries.

This may be achieved by using AppCompatCheckBox. You can use app:buttonCompat="@drawable/selector_drawable" to change the selector.

It's working with PNGs, but I didn't find a way for it to work with Vector Drawables.

On a SLES12 machine you can use Ctrl+PageUp and Ctrl+PageDown to navigate between tabs by default. You can always change these keys from Preferences window by browsing through "keys" section under "General" category. This process is well explained by Victor and VonC above.

You can also use chr(176) to print the degree sign. Here is an example using python 3.6.5 interactive shell:

Please read the example in rfc6749 sec 7.1 first.

The bearer token is a type of access token, which does NOT require PoP(proof-of-possession) mechanism.

PoP means kind of multi-factor authentication to make access token more secure. ref

Proof-of-Possession refers to Cryptographic methods that mitigate the risk of Security Tokens being stolen and used by an attacker. In contrast to 'Bearer Tokens', where mere possession of the Security Token allows the attacker to use it, a PoP Security Token cannot be so easily used - the attacker MUST have both the token itself and access to some key associated with the token (which is why they are sometimes referred to 'Holder-of-Key' (HoK) tokens).

Maybe it's not the case, but I would say,

• access token = payment methods
• bearer token = cash
• access token with PoP mechanism = credit card (signature or password will be verified, sometimes need to show your ID to match the name on the card)

BTW, there's a draft of "OAuth 2.0 Proof-of-Possession (PoP) Security Architecture" now.

NOTE: The make tool reads the makefile and checks the modification time-stamps of the files at both the side of ':' symbol in a rule.

Example

In a directory 'test' following files are present:

prerit@vvdn105:~/test$ ls
hello  hello.c  makefile

In makefile a rule is defined as follows:

hello:hello.c
    cc hello.c -o hello

Now assume that file 'hello' is a text file containing some data, which was created after 'hello.c' file. So the modification (or creation) time-stamp of 'hello' will be newer than that of the 'hello.c'. So when we will invoke 'make hello' from command line, it will print as:

make: `hello' is up to date.

Now access the 'hello.c' file and put some white spaces in it, which doesn't affect the code syntax or logic then save and quit. Now the modification time-stamp of hello.c is newer than that of the 'hello'. Now if you invoke 'make hello', it will execute the commands as:

cc hello.c -o hello

And the file 'hello' (text file) will be overwritten with a new binary file 'hello' (result of above compilation command).

If we use .PHONY in makefile as follow:

.PHONY:hello

hello:hello.c
    cc hello.c -o hello

and then invoke 'make hello', it will ignore any file present in the pwd 'test' and execute the command every time.

Now suppose, that 'hello' target has no dependencies declared:

hello:
    cc hello.c -o hello

and 'hello' file is already present in the pwd 'test', then 'make hello' will always show as:

make: `hello' is up to date.

The problem is GROUP BY - if you group results by Locus, you only get one result per locus.

Try:

SELECT * FROM Genes WHERE Locus = '3' AND Chromosome = '10';

If you prefer using HAVING syntax, then GROUP BY id or something that is not repeating in the result set.

I had the same problem and solved it by going to File -> Project Structure... -> Suggestions and then Apply all. Like suggested by @JeffinJ I think the problem was because of the Gradle plugin update.

Yes, there is std::byte (defined in <cstddef>).

C++ 17 introduced it.

Another alternative that uses an external library is _.has() from Lodash.

E.g.

_.has(a, 'b.c')

is equal to

(a && a.b && a.b.c)

EDIT: As noted in the comments, you lose out on Typescript's type inference when using this method. E.g. Assuming that one's objects are properly typed, one would get a compilation error with (a && a.b && a.b.z) if z is not defined as a field of object b. But using _.has(a, 'b.z'), one would not get that error.

You can use for it the is operator. You can then check if object is specific type by writing:

if (myObject is string)
{
  DoSomething()
}

I might be too late to join the game but what the heck huh? :)

Do you think this is a threading issue? How are you using the output of this method for example? OR

Can we change your code to do something as simple as:

Calendar calendar1 = Calendar.getInstance();
    Calendar calendar2 = Calendar.getInstance();
    calendar1.set(<your earlier date>);
    calendar2.set(<your current date>);
    long milliseconds1 = calendar1.getTimeInMillis();
    long milliseconds2 = calendar2.getTimeInMillis();
    long diff = milliseconds2 - milliseconds1;
    long diffSeconds = diff / 1000;
    long diffMinutes = diff / (60 * 1000);
    long diffHours = diff / (60 * 60 * 1000);
    long diffDays = diff / (24 * 60 * 60 * 1000);
    System.out.println("\nThe Date Different Example");
    System.out.println("Time in milliseconds: " + diff
 + " milliseconds.");
    System.out.println("Time in seconds: " + diffSeconds
 + " seconds.");
    System.out.println("Time in minutes: " + diffMinutes 
+ " minutes.");
    System.out.println("Time in hours: " + diffHours 
+ " hours.");
    System.out.println("Time in days: " + diffDays 
+ " days.");
  }

It is evident to me that GitLens is the most popular extension for Git history.

What I like the most it can provide you side annotations when some line has been changed the last time and by whom.

Because you need parentheses around the value your looking for. So here : document.querySelector('a[data-a="1"]')

If you don't know in advance the value but is looking for it via variable you can use template literals :

Say we have divs with data-price

<div data-price="99">My okay price</div>
<div data-price="100">My too expensive price</div>

We want to find an element but with the number that someone chose (so we don't know it):

// User chose 99    
let chosenNumber = 99
document.querySelector(`[data-price="${chosenNumber}"`]

I've chmoded my keypair to 600 in order to get into my personal instance last night,

And this is the way it is supposed to be.

From the EC2 documentation we have "If you're using OpenSSH (or any reasonably paranoid SSH client) then you'll probably need to set the permissions of this file so that it's only readable by you." The Panda documentation you link to links to Amazon's documentation but really doesn't convey how important it all is.

The idea is that the key pair files are like passwords and need to be protected. So, the ssh client you are using requires that those files be secured and that only your account can read them.

Setting the directory to 700 really should be enough, but 777 is not going to hurt as long as the files are 600.

Any problems you are having are client side, so be sure to include local OS information with any follow up questions!

Sessions would be good choice for you. Take a look at these two examples from PHP Manual:

Code of page1.php

<?php
// page1.php

session_start();

echo 'Welcome to page #1';

$_SESSION['favcolor'] = 'green';
$_SESSION['animal']   = 'cat';
$_SESSION['time']     = time();

// Works if session cookie was accepted
echo '<br /><a href="page2.php">page 2</a>';

// Or pass along the session id, if needed
echo '<br /><a href="page2.php?' . SID . '">page 2</a>';
?>

Code of page2.php

<?php
// page2.php

session_start();

echo 'Welcome to page #2<br />';

echo $_SESSION['favcolor']; // green
echo $_SESSION['animal'];   // cat
echo date('Y m d H:i:s', $_SESSION['time']);

// You may want to use SID here, like we did in page1.php
echo '<br /><a href="page1.php">page 1</a>';
?>

To clear up things - SID is PHP's predefined constant which contains session name and its id. Example SID value:

PHPSESSID=d78d0851898450eb6aa1e6b1d2a484f1

Steven is right, in theory:

the “correct” way to center a table using CSS. Conforming browsers ought to center tables if the left and right margins are equal. The simplest way to accomplish this is to set the left and right margins to “auto.” Thus, one might write in a style sheet:

table
{ 
    margin-left: auto;
    margin-right: auto;
}

But the article mentioned in the beginning of this answer gives you all the other way to center a table.

An elegant css cross-browser solution: This works in both MSIE 6 (Quirks and Standards), Mozilla, Opera and even Netscape 4.x without setting any explicit widths:

div.centered 
{
    text-align: center;
}

div.centered table 
{
    margin: 0 auto; 
    text-align: left;
}


<div class="centered">
    <table>
    …
    </table>
</div>

Perhaps you have the compiler settings for your IDE set to Java 1.4 mode even if you are using a Java 5 JDK? Otherwise I agree with the other people who already mentioned autoboxing/unboxing.

Once I had this "simple" task and I used (new Date()).getTimezoneOffset() - the approach that is widely suggested here. But it turned out that the solution wasn't quite right. For some undocumented reasons in my case new Date() was returning GMT+0200 when new Date(0) was returning GMT+0300 which was right. Since then I always use

(new Date(0)).getTimezoneOffset() to get a correct timeshift.

You can use the reversed function with a list comprehesive. But I don't understand why this method was eliminated in python 3, was unnecessarily.

string = [ char for char in reversed(string)]

to send over gmail, you need to use an encrypted connection. this is not possible with telnet alone, but you can use tools like openssl

either connect using the starttls option in openssl to convert the plain connection to encrypted...

openssl s_client -starttls smtp -connect smtp.gmail.com:587 -crlf -ign_eof

or connect to a ssl sockect directly...

openssl s_client -connect smtp.gmail.com:465 -crlf -ign_eof

EHLO localhost

after that, authenticate to the server using the base64 encoded username/password

AUTH PLAIN AG15ZW1haWxAZ21haWwuY29tAG15cGFzc3dvcmQ=

to get this from the commandline:

echo -ne '\[email protected]\00password' | base64
AHVzZXJAZ21haWwuY29tAHBhc3N3b3Jk

then continue with "mail from:" like in your example

example session:

openssl s_client -connect smtp.gmail.com:465 -crlf -ign_eof

The visible width of an element is width + padding + border + outline, so it seems that you are forgetting about the border on the input element. That is, to say, that the default border width for an input element on most (some?) browsers is actually calculated as 2px, not one. Hence your input is appearing as 2px wider. Try explicitly setting the border-width on the input, or making your div wider.

No need for css, you can just use the HR tag from HTML

<hr />

Boolean primitive type is atomic for write and read operations, volatile guarantees the happens-before principle. So if you need a simple get() and set() then you don't need the AtomicBoolean.

On the other hand if you need to implement some check before setting the value of a variable, e.g. "if true then set to false", then you need to do this operation atomically as well, in this case use compareAndSet and other methods provided by AtomicBoolean, since if you try to implement this logic with volatile boolean you'll need some synchronization to be sure that the value has not changed between get and set.

What kind of field is this? The IN operator cannot be used with a single field, but is meant to be used in subqueries or with predefined lists:

-- subquery
SELECT a FROM x WHERE x.b NOT IN (SELECT b FROM y);
-- predefined list
SELECT a FROM x WHERE x.b NOT IN (1, 2, 3, 6);

If you are searching a string, go for the LIKE operator (but this will be slow):

-- Finds all rows where a does not contain "text"
SELECT * FROM x WHERE x.a NOT LIKE '%text%';

If you restrict it so that the string you are searching for has to start with the given string, it can use indices (if there is an index on that field) and be reasonably fast:

-- Finds all rows where a does not start with "text"
SELECT * FROM x WHERE x.a NOT LIKE 'text%';

Your file should directly be under the project folder, and not inside any other sub-folder.

If the folder of your project is named for e.g. AProject, it should be in the same place as your src folder.

Aproject
        src
        word.txt

I use this website and this pattern do leap year validation as well.

<input type="text" pattern="(?:19|20)[0-9]{2}-(?:(?:0[1-9]|1[0-2])-(?:0[1-9]|1[0-9]|2[0-9])|(?:(?!02)(?:0[1-9]|1[0-2])-(?:30))|(?:(?:0[13578]|1[02])-31))" required />

1. markers is not a JSON object. It is a normal JavaScript object.
2. Read about the data: option:

   Data to be sent to the server. It is converted to a query string, if not already a string.

If you want to send the data as JSON, you have to encode it first:

data: {markers: JSON.stringify(markers)}

jQuery does not convert objects or arrays to JSON automatically.

But I assume the error message comes from interpreting the response of the service. The text you send back is not JSON. JSON strings have to be enclosed in double quotes. So you'd have to do:

return "\"received markers\"";

I'm not sure if your actual problem is sending or receiving the data.

While it does look simple enough to implement on your own with a timeout and a couple of mouse event handlers, it gets a bit more complicated when you consider cases like click-drag-release, supporting both press and long-press on the same element, and working with touch devices like the iPad. I ended up using the longclick jQuery plugin (Github), which takes care of that stuff for me. If you only need to support touchscreen devices like mobile phones, you might also try the jQuery Mobile taphold event.

Got here through google because i was looking for a good way to do things on the ui thread after being inside a Task.Run call - Using the following code you can use await to get back to the UI Thread again.

I hope this helps someone.

public static class UI
{
    public static DispatcherAwaiter Thread => new DispatcherAwaiter();
}

public struct DispatcherAwaiter : INotifyCompletion
{
    public bool IsCompleted => Application.Current.Dispatcher.CheckAccess();

    public void OnCompleted(Action continuation) => Application.Current.Dispatcher.Invoke(continuation);

    public void GetResult() { }

    public DispatcherAwaiter GetAwaiter()
    {
        return this;
    }
}

Usage:

... code which is executed on the background thread...
await UI.Thread;
... code which will be run in the application dispatcher (ui thread) ...

If the directory doesn't exist you need to create it. Java won't create it by itself since the File class is just a link to an entity that can also not exist at all.

As you stated the error is that the file cannot be created. If you read the documentation of PrintWriter constructor you can see

FileNotFoundException - If the given string does not denote an existing, writable regular file and a new regular file of that name cannot be created, or if some other error occurs while opening or creating the file

You should try creating a path for the folder it contains before:

File file = new File("C:/Users/Me/Desktop/directory/file.txt");
file.getParentFile().mkdirs();

PrintWriter printWriter = new PrintWriter(file);

i it integer, int to Integer

Integer intObj = new Integer(i);

add to collection

list.add(String.valueOf(intObj));

Yes, you're right. With the css() method you can retrieve the desired css value stored in the DOM. You can read more about this at: http://api.jquery.com/css/

But if you want to get its position you can check offset() and position() methods to get it's position.

/dt is the commad which lists you all the tables present in a database. using
/d command and /d+ we can get the details of a table. The sysntax will be like
* /d table_name (or) \d+ table_name

Simply casting to List<TestB> almost works; but it doesn't work because you can't cast a generic type of one parameter to another. However, you can cast through an intermediate wildcard type and it will be allowed (since you can cast to and from wildcard types, just with an unchecked warning):

List<TestB> variable = (List<TestB>)(List<?>) collectionOfListA;

You can do it like

<button v-on:click="Function1(); Function2();"></button>

OR

<button @click="Function1(); Function2();"></button>

Make sure that your package is installed in your $GOPATH directory or already inside your workspace/package.

For example: if your $GOPATH = "c:\go", make sure that the package inside C:\Go\src\pkgName

mmap has the advantage when you have random access on big files. Another advantage is that you access it with memory operations (memcpy, pointer arithmetic), without bothering with the buffering. Normal I/O can sometimes be quite difficult when using buffers when you have structures bigger than your buffer. The code to handle that is often difficult to get right, mmap is generally easier. This said, there are certain traps when working with mmap. As people have already mentioned, mmap is quite costly to set up, so it is worth using only for a given size (varying from machine to machine).

For pure sequential accesses to the file, it is also not always the better solution, though an appropriate call to madvise can mitigate the problem.

You have to be careful with alignment restrictions of your architecture(SPARC, itanium), with read/write IO the buffers are often properly aligned and do not trap when dereferencing a casted pointer.

You also have to be careful that you do not access outside of the map. It can easily happen if you use string functions on your map, and your file does not contain a \0 at the end. It will work most of the time when your file size is not a multiple of the page size as the last page is filled with 0 (the mapped area is always in the size of a multiple of your page size).

Had same issue this end of week, only Firefox will not accept certificate... The solution for me has been to add, in the apache configuration of the website, the intermediate certificate with the following line :

SSLCACertificateFile /your/path/to/ssl_ca_certs.pem

Find more infomration on https://httpd.apache.org/docs/2.4/fr/mod/mod_ssl.html

Might be better to use a choice, don't have to type (or possibly mistype) your expressions more than once, and allows you to follow additional different behaviors.

I very often use count(/html/body) = 0, as the specific number of nodes is more interesting than the set. For example... when there is unexpectedly more than 1 node that matches your expression.

<xsl:choose>
    <xsl:when test="/html/body">
         <!-- Found the node(s) -->
    </xsl:when>
    <!-- more xsl:when here, if needed -->
    <xsl:otherwise>
         <!-- No node exists -->
    </xsl:otherwise>
</xsl:choose>

I have a simpler idea. Use LINQ with a new selection.

public class Fruit
{
  public string Name {get; set;}
  public int SeedCount {get; set;}
}

void SomeMethod()
{
  List<Fruit> originalFruits = new List<Fruit>();
  originalFruits.Add(new Fruit {Name="Apple", SeedCount=10});
  originalFruits.Add(new Fruit {Name="Banana", SeedCount=0});

  //Deep Copy
  List<Fruit> deepCopiedFruits = from f in originalFruits
              select new Fruit {Name=f.Name, SeedCount=f.SeedCount};
}

SELECT ROUND((6 - 3 * RAND()), 0)

git show somebranch:path/to/your/file

you can also do multiple files and have them concatenated:

git show branchA~10:fileA branchB^^:fileB

You do not have to provide the full path to the file, relative paths are acceptable e.g.:

git show branchA~10:../src/hello.c

If you want to get the file in the local directory (revert just one file) you can checkout:

git checkout somebranch^^^ -- path/to/file

This is a bad way of doing it, but it worked for me when trying to interpret escaped octals passed in a string argument.

input_string = eval('b"' + sys.argv[1] + '"')

It's worth mentioning that there is a difference between eval and ast.literal_eval (eval being way more unsafe). See Using python's eval() vs. ast.literal_eval()?

You need to specify which object you're calling getElementById from. In this case you can use document. You also can't just call .value on any element directly. For example if the element is textbox .value will return the value, but if it's a div it will not have a value.

You also have a wrong condition, you're checking

if (myEle == null)

which you should change to

if (myEle != null)

var myEle = document.getElementById("myElement");
if(myEle != null) { 
    var myEleValue= myEle.value; 
}

All answers are great. Here is an example use case for multiple add address: The ability to add as many email you want on demand with a web form:

See it in action with jsfiddle here (except the php processor)

### Send unlimited email with a web form
# Form for continuously adding e-mails:
<button type="button" onclick="emailNext();">Click to Add Another Email.</button>
<div id="addEmail"></div>
<button type="submit">Send All Emails</button>
# Script function:
<script>
function emailNext() {
    var nextEmail, inside_where;
    nextEmail = document.createElement('input');
    nextEmail.type = 'text';
    nextEmail.name = 'emails[]';
    nextEmail.className = 'class_for_styling';
    nextEmail.style.display = 'block';
    nextEmail.placeholder  = 'Enter E-mail Here';
    inside_where = document.getElementById('addEmail');
    inside_where.appendChild(nextEmail);
    return false;
}
</script>
# PHP Data Processor:
<?php
// ...
// Add the rest of your $mailer here...
if ($_POST[emails]){
    foreach ($_POST[emails] AS $postEmail){
        if ($postEmail){$mailer->AddAddress($postEmail);}
    }
} 
?>

So what it does basically is to generate a new input text box on every click with the name "emails[]".

The [] added at the end makes it an array when posted.

Then we go through each element of the array with "foreach" on PHP side adding the:

    $mailer->AddAddress($postEmail);

You could download it from a Android 4.0 phone and then mount the system image rw and copy it over.

Didnt tried it before but it should work.

You can try this simple android dialog popup library. It is very simple to use on your activity.

When submit button is clicked try following code after including above lib in your code

Pop.on(this)
   .with()
   .title(R.string.title) //ignore if not needed
   .icon(R.drawable.icon) //ignore if not needed
   .cancelable(false) //ignore if not needed
   .layout(R.layout.custom_pop)
   .when(new Pop.Yah() {
       @Override
       public void clicked(DialogInterface dialog, View view) {
           Toast.makeText(getBaseContext(), "Yah button clicked", Toast.LENGTH_LONG).show();
       }
   }).show();

Add one line in your gradle and you good to go

dependencies {
    compile 'com.vistrav:pop:2.0'
}

Simply, @Id: This annotation specifies the primary key of the entity. 

@GeneratedValue: This annotation is used to specify the primary key generation strategy to use. i.e Instructs database to generate a value for this field automatically. If the strategy is not specified by default AUTO will be used. 

GenerationType enum defines four strategies: 
1. Generation Type . TABLE, 
2. Generation Type. SEQUENCE,
3. Generation Type. IDENTITY   
4. Generation Type. AUTO

GenerationType.SEQUENCE

With this strategy, underlying persistence provider must use a database sequence to get the next unique primary key for the entities. 

GenerationType.TABLE

With this strategy, underlying persistence provider must use a database table to generate/keep the next unique primary key for the entities. 

GenerationType.IDENTITY
This GenerationType indicates that the persistence provider must assign primary keys for the entity using a database identity column. IDENTITY column is typically used in SQL Server. This special type column is populated internally by the table itself without using a separate sequence. If underlying database doesn't support IDENTITY column or some similar variant then the persistence provider can choose an alternative appropriate strategy. In this examples we are using H2 database which doesn't support IDENTITY column.

GenerationType.AUTO
This GenerationType indicates that the persistence provider should automatically pick an appropriate strategy for the particular database. This is the default GenerationType, i.e. if we just use @GeneratedValue annotation then this value of GenerationType will be used.

The Allow-Control-Allow-Origin plugin for Chrome does not work. This is for MacOS

I added alias chrome='open -n -a /Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --args --user-data-dir --disable-web-security' to my .profile as an alias.

The other commands will disable my other extensions and this will boot your normal chrome with cors disabled

"Server not found in Kerberos database" error can happen if you have registered the SPN to multiple users/computers.

You can check that with:

$ SetSPN -Q ServicePrincipalName
( SetSPN -Q HTTP/my.server.local@MYDOMAIN )

"#if one" means that if "#define one" has been written "#if one" is executed otherwise "#ifndef one" is executed.

This is just the C Pre-Processor (CPP) Directive equivalent of the if, then, else branch statements in the C language.

i.e. if {#define one} then printf("one evaluates to a truth "); else printf("one is not defined "); so if there was no #define one statement then the else branch of the statement would be executed.

There is no such functionality in jQuery. Use JSON.stringify or alternatively any jQuery plugin with similar functionality (e.g jquery-json).

In Xcode 11.3 swift 5.2 and later

Use

var isEmpty: Bool { get } 

Example

let lang = "Swift 5"

if lang.isEmpty {
   print("Empty string")
}

If you want to ignore white spaces

if lang.trimmingCharacters(in: .whitespaces).isEmpty {
   print("Empty string")
}

Try this:

public void ShowMain()
    {
        if(auth()) // a method that returns true when the user exists.
        { 
            this.Close();
            System.Threading.Thread t = new System.Threading.Thread(new System.Threading.ThreadStart(Main));
            t.Start();
        }
        else
        {
            MessageBox.Show("Invalid login details.");
        }         
    }
   [STAThread]
   public void Main()
   {
      Application.EnableVisualStyles();
      Application.SetCompatibleTextRenderingDefault(false);
      Application.Run(new Main());

   }

You must call the new form in a diferent thread apartment, if I not wrong, because of the call system of windows' API and COM interfaces.

One advice: this system is high insecure, because you can change the if condition (in MSIL) and it's "a children game" to pass out your security. You need a stronger system to secure your software like obfuscate or remote login or something like this.

Hope this helps.

Select your results by clicking in the top left corner, right click and select "Copy with Headers". Paste in excel. Done!

Though it won't work for numbers, you can check if the lowercase and uppercase values are same or not, For non-alphabetic characters they will be same, You should check for number before this for better usability

Your query execution will return list of Object[].

List result_source = LoadSource.list();
for(Object[] objA : result_source) {
    // read it all
}

Use ls -s to list file size, or if you prefer ls -sh for human readable sizes.

For directories use du, and again, du -h for human readable sizes.

Step 1 : Check the proxy configured in eclipse is correct or not ? (Window->Preferences->General->Network Connections).

Step 2 : Right Click on Project-> Go to Maven -> Update the project

Step 3: Run as Maven Install.

Sometimes you want to have your GridView as simple as:

  <asp:GridView ID="grid" runat="server" />

You don't want to specify any BoundField, you just want to bind your grid to DataReader. The following code helped me to format DateTime in this situation.

protected void Page_Load(object sender, EventArgs e)
{
  grid.RowDataBound += grid_RowDataBound;
  // Your DB access code here...
  // grid.DataSource = cmd.ExecuteReader(CommandBehavior.CloseConnection);
  // grid.DataBind();
}

void grid_RowDataBound(object sender, GridViewRowEventArgs e)
{
  if (e.Row.RowType != DataControlRowType.DataRow)
    return;
  var dt = (e.Row.DataItem as DbDataRecord).GetDateTime(4);
  e.Row.Cells[4].Text = dt.ToString("dd.MM.yyyy");
}

Alright so for me, the error being fixed is when there are different versions of python installed and yum can't find a certain .so file and throws an exception.
yum wants 2.7.5 according to the error.

which python gives me /usr/bin/python
python --version gives me 2.7.5

The fix for me was append /lib64 to the LD_LIBRARY_PATH environment variable. The relevant content is /lib64/python2.7 and /lib64/python3.6.

export LD_LIBRARY_PATH=/lib64:$LD_LIBRARY_PATH

Fixed the yum error for me with multiple python versions installed.

Define mutable array

// 2 dimensional array of arrays of Ints 
var arr = [[Int]]() 

OR:

// 2 dimensional array of arrays of Ints 
var arr: [[Int]] = [] 

OR if you need an array of predefined size (as mentioned by @0x7fffffff in comments):

// 2 dimensional array of arrays of Ints set to 0. Arrays size is 10x5
var arr = Array(count: 3, repeatedValue: Array(count: 2, repeatedValue: 0))

// ...and for Swift 3+:
var arr = Array(repeating: Array(repeating: 0, count: 2), count: 3)

Change element at position

arr[0][1] = 18

OR

let myVar = 18
arr[0][1] = myVar

Change sub array

arr[1] = [123, 456, 789] 

OR

arr[0] += 234

OR

arr[0] += [345, 678]

If you had 3x2 array of 0(zeros) before these changes, now you have:

[
  [0, 0, 234, 345, 678], // 5 elements!
  [123, 456, 789],
  [0, 0]
]

So be aware that sub arrays are mutable and you can redefine initial array that represented matrix.

Examine size/bounds before access

let a = 0
let b = 1

if arr.count > a && arr[a].count > b {
    println(arr[a][b])
}

Remarks: Same markup rules for 3 and N dimensional arrays.

Problem

The accepted answer:

const initialState = {
    /* etc */
};

class MyComponent extends Component {
    constructor(props) {
        super(props)
        this.state = initialState;
    }
    reset() {
        this.setState(initialState);
    }
    /* etc */
}

unfortunately is not correct.

initialState is passed as a reference to this.state, so whenever you change state you also change initialState (const doesn't really matter here). The result is that you can never go back to initialState.

Solution

You have to deep copy initialState to state, then it will work. Either write a deep copy function yourself or use some existing module like this.

Option 1- From Studio

In Android Studio, go to File > Project Structure. Then select the "project" tab on the left.

Your Gradle version will be displayed here.

Option 2- gradle-wrapper.properties

If you are using the Gradle wrapper, then your project will have a gradle/wrapper/gradle-wrapper.properties folder.

This file should contain a line like this:

distributionUrl=https\://services.gradle.org/distributions/gradle-2.2.1-all.zip

This determines which version of Gradle you are using. In this case, gradle-2.2.1-all.zip means I am using Gradle 2.2.1.

Option 3- Local Gradle distribution

If you are using a version of Gradle installed on your system instead of the wrapper, you can run gradle --version to check.

I'd like to note that it's usually preferable to change the class of the node instead of it's style and let CSS handle what that means.

Continuing with what Dave Ward said:

• You can't set the Visible property to false because the control will not be rendered.
• You should use the Style property to set it's display to none.

Page/Control design

<asp:Label runat="server" ID="Label1" Style="display: none;" />

<asp:Button runat="server" ID="Button1" />

Code behind

Somewhere in the load section:

Label label1 = (Label)FindControl("Label1");
((Label)FindControl("Button1")).OnClientClick = "ToggleVisibility('" + label1.ClientID + "')";

Javascript file

function ToggleVisibility(elementID)
{
    var element = document.getElementByID(elementID);

    if (element.style.display = 'none')
    {
        element.style.display = 'inherit';
    }
    else
    {
        element.style.display = 'none';
    }
}

Of course, if you don't want to toggle but just to show the button/label then adjust the javascript method accordingly.

The important point here is that you need to send the information about the ClientID of the control that you want to manipulate on the client side to the javascript file either setting global variables or through a function parameter as in my example.

It will convert Enum Constant into Camel Case. It would be helpful for anyone who is looking for such funtionality.

        public String langCode() {
            return this.code;
        }

        public String toCamelCase(TRANSLATE_LANGUAGES lang) {
            String toString = lang.toString();
            if (toString.contains("_")) {
                String st = toUpperLowerCase(toString.split("_"));
            }

            return "";
        }

        private String toUpperLowerCase(String[] tempString) {
            StringBuilder builder = new StringBuilder();

            for (String temp : tempString) {

                String char1 = temp.substring(0, 1);
                String restString = temp.substring(1, temp.length()).toLowerCase();
                builder.append(char1).append(restString).append(" ");

            }

            return builder.toString();
        }
    }

Use this function for date conversion, its working fine when your device in 24/12 hr format

See https://developer.apple.com/library/archive/qa/qa1480/_index.html

func convertDateFormatter(fromFormat:String,toFormat:String,_ dateString: String) -> String{
    let formatter = DateFormatter()
    formatter.locale = Locale(identifier: "en_US_POSIX")
    formatter.dateFormat = fromFormat
    let date = formatter.date(from: dateString)
    formatter.dateFormat = toFormat
    return  date != nil ? formatter.string(from: date!) : ""
}

If you're using 64-bit but still having problem even after installing AccessDatabaseEngine, see this post, it solved the problem for me.

i.e. You need to install this AccessDatabaseEngine

Can you post your code? I'm not finding any issue with this. Tested on Firefox 3.01/safari 3.1.2 with:

function showMe(e) {
// i am spammy!
  alert(e.value);
}
....
<input type="text" id="foo" value="bar" onkeyup="showMe(this)" />

If you're using Ubuntu then use the following:

sudo chown -R ubuntu /var/www/html

sudo chmod -R 755 /var/www/html

While all of the other answers work, they all have one big problem: it is up to the browser to decide what to do if they encounter a Location header. Usually browser stop processing the request and redirect to the URI indicated with the Location header. But a malicious user could just ignore the Location header and continue its request. Furthermore there may be other things that cause the php interpreter to continue evaluating the script past the Location header, which is not what you intended.

Image this:

<?php
if (!logged_id()) {
    header("Location:login.php");
}

delete_everything();
?>

What you want and expected is that not logged in users are redirected to the login page, so that only logged in users can delete_everything. But if the script gets executed past the Location header still everything gets deleted. Thus, it is import to ALWAYS put an exit after a Location header, like this:

<?php
if (!logged_id()) {
    header("Location:login.php");
    exit; // <- don't forget this!
}

delete_everything();
?>

So, to answer your question: to redirect from a php page to another page (not just php, you can redirect to any page this way), use this:

<?php 

header("Location:http://www.example.com/some_page.php"); 
exit; // <- don't forget this!

?>

Small note: the HTTP standard says that you must provide absolute URLs in the Location header (http://... like in my example above) even if you just want to redirect to another file on the same domain. But in practice relative URLs (Location:some_page.php) work in all browsers, though not being standard compliant.

private void indBoxProject_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    int NewProjID = (e.AddedItems[0] as kProject).ProjectID;
    this.MyProject = new kProject(NewProjID);
    LoadWorkPhase();
}

The use of the e.AddedItems[0] as kProject where kProject is a class that holds the data worked for me as it was defaulting to the RemovedItems[0] before I have made this explicit distinction. Thanks SwDevMan81 for the initial information that answered this question for me.

In some cases a one-way request without a response can be fired to a TCP server, without a SSL certificate. A TCP server, in contrast to a HTTP server, will catch you request. However there will be no access to any data sent from the browser, because the browser will not send any data without a positive certificate check. And in special cases even a bare TCP signal without any data is enough to execute some tasks. For example for an IoT device within a LAN to start a connection to an external service. Link

This is a kind of a "Wake Up" trigger, that works on a port without any security.

In case a response is needed, this can be implemented using a secured public https server, which can send the needed data back to the browser using e.g. Websockets.

Summary

With either string concatenation or string interpolation (via template literals).

Here with JavaScript template literal:

function geoPreview() {
    var lat = document.getElementById("lat").value;
    var long = document.getElementById("long").value;

    window.location.href = `http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=${lat}&lon=${long}&setLatLon=Set`;
}

Both parameters are unused and can be removed.

Remarks

String Concatenation

Join strings with the + operator:

window.location.href = "http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=" + elemA + "&lon=" + elemB + "&setLatLon=Set";

String Interpolation

For more concise code, use JavaScript template literals to replace expressions with their string representations. Template literals are enclosed by `` and placeholders surrounded with ${}:

window.location.href = `http://www.gorissen.info/Pierre/maps/googleMapLocation.php?lat=${elemA}&lon=${elemB}&setLatLon=Set`;

Template literals are available since ECMAScript 2015 (ES6).

if you create a console application, console will stay opened until you close the application.

if you already creat an application and you dont know how to open a console, you can change the subsystem as Console(/Subsystem:Console) in project configurations -> linker -> system.

In my case I got this error when I had mistakenly named a class the same as the class it was inheriting from.
