As mentioned by @Jim, the file organization is described here. Reproduced for ease of discovery:

For Python modules, the typical layout is:

Lib/<module>.py
Modules/_<module>.c (if there’s also a C accelerator module)
Lib/test/test_<module>.py
Doc/library/<module>.rst

For extension-only modules, the typical layout is:

Modules/<module>module.c
Lib/test/test_<module>.py
Doc/library/<module>.rst

For builtin types, the typical layout is:

Objects/<builtin>object.c
Lib/test/test_<builtin>.py
Doc/library/stdtypes.rst

For builtin functions, the typical layout is:

Python/bltinmodule.c
Lib/test/test_builtin.py
Doc/library/functions.rst

Some exceptions:

builtin type int is at Objects/longobject.c
builtin type str is at Objects/unicodeobject.c
builtin module sys is at Python/sysmodule.c
builtin module marshal is at Python/marshal.c
Windows-only module winreg is at PC/winreg.c

Given a quadratic equation: x² − 4.0000000 x + 3.9999999 = 0, the exact roots to 10 significant digits are, r₁ = 2.000316228 and r₂ = 1.999683772.

Using float and double, we can write a test program:

#include <stdio.h>
#include <math.h>

void dbl_solve(double a, double b, double c)
{
    double d = b*b - 4.0*a*c;
    double sd = sqrt(d);
    double r1 = (-b + sd) / (2.0*a);
    double r2 = (-b - sd) / (2.0*a);
    printf("%.5f\t%.5f\n", r1, r2);
}

void flt_solve(float a, float b, float c)
{
    float d = b*b - 4.0f*a*c;
    float sd = sqrtf(d);
    float r1 = (-b + sd) / (2.0f*a);
    float r2 = (-b - sd) / (2.0f*a);
    printf("%.5f\t%.5f\n", r1, r2);
}   

int main(void)
{
    float fa = 1.0f;
    float fb = -4.0000000f;
    float fc = 3.9999999f;
    double da = 1.0;
    double db = -4.0000000;
    double dc = 3.9999999;
    flt_solve(fa, fb, fc);
    dbl_solve(da, db, dc);
    return 0;
}  

Running the program gives me:

2.00000 2.00000
2.00032 1.99968

Note that the numbers aren't large, but still you get cancellation effects using float.

(In fact, the above is not the best way of solving quadratic equations using either single- or double-precision floating-point numbers, but the answer remains unchanged even if one uses a more stable method.)

There is actually quite a simple css solution which even works on IE8:

.container {_x000D_
  position: relative;_x000D_
  overflow: hidden;_x000D_
  /* Width and height can be anything. */_x000D_
  width: 50vw;_x000D_
  height: 50vh;_x000D_
}_x000D_
_x000D_
img {_x000D_
  position: absolute;_x000D_
  /* Position the image in the middle of its container. */_x000D_
  top: -9999px;_x000D_
  right: -9999px;_x000D_
  bottom: -9999px;_x000D_
  left: -9999px;_x000D_
  margin: auto;_x000D_
  /* The following values determine the exact image behaviour. */_x000D_
  /* You can simulate background-size: cover/contain/etc._x000D_
     by changing between min/max/standard width/height values._x000D_
     These values simulate background-size: cover_x000D_
  */_x000D_
  min-width: 100%;_x000D_
  min-height: 100%;_x000D_
}

<div class="container">_x000D_
    <img src="http://placehold.it/200x200" alt="" />_x000D_
</div>

This works:

public class Split
{
    public static void main(String...args)
    {
        String a = "%abcdef&Ghijk%xyz";
        String b[] = a.split("%", 2);
        
        System.out.println("Value = "+b[1]);
    }
}

If it's socket related read this file

/etc/mysql/my.cnf

and see what is the standard socket location. It's a line like:

socket = /var/run/mysqld/mysqld.sock

now create an alias for your shell like:

alias mysql="mysql --socket=/var/run/mysqld/mysqld.sock"

This way you don't need root privileges.

With SQLServer 2005 Express, what I found was that even with autocommit off, insertions into a Db table were committed without my actually issuing a commit command from the Management Studio session. The only difference was, when autocommit was off, I could roll back all the insertions; with *autocommit on, I could not.* Actually, I was wrong. With autocommit mode off, I see the changes only in the QA (Query Analyzer) window from which the commands were issued. If I popped a new QA (Query Analyzer) window, I do not see the changes made by the first window (session), i.e. they are NOT committed! I had to issue explicit commit or rollback commands to make changes visible to other sessions(QA windows) -- my bad! Things are working correctly.

I had a big dataset and .loc[] was taking too long so I found a vectorized way to do it. Recall that you can set a column to a logical operator, so this works:

file['Flag'] = (file['Claim_Amount'] > 0)

This gives a Boolean, which I wanted, but you can multiply it by, say, 1 to make an Integer.

You can do it as follows:

> x<-c(2, 4, 6, 9, 10) # the list
> y<-c(4, 9, 10) # values to be removed

> idx = which(x %in% y ) # Positions of the values of y in x
> idx
[1] 2 4 5
> x = x[-idx] # Remove those values using their position and "-" operator
> x
[1] 2 6

Shortly

> x = x[ - which(x %in% y)]

robotex tools which are free will let you do this but they make you enter the ip of the domain first:

1. find out the ip (there's a good ff plugin which does this but I can't post the link cos this is my first post here!)
2. do an ip search on robotex: http://www.robtex.com/ip/
3. in the results page that follows click on the domain you're interested in>
4. you are taken to a page that lists all subdomains + a load of other information such as mail server info

Not really anything to do with jQuery, but if you want to trim a pattern from a string, then use a regular expression:

<textarea id="ta0"></textarea>
<button onclick="
  var ta = document.getElementById('ta0');
  var text = 'some<br>text<br />to<br/>replace';
  var re = /<br *\/?>/gi;
  ta.value = text.replace(re, '\n');
">Add stuff to text area</button>

Neither is more correct, so take your pick. The empty return; statement is provided to allow a return in a void function from somewhere other than the end. No other reason I believe.

Currently, I know about the following three ways:

1. The @Value annotation

    @Value("${<property.name>}")
    private static final <datatype> PROPERTY_NAME;

• In my experience there are some situations when you are not able to get the value or it is set to null. For instance, when you try to set it in a preConstruct() method or an init() method. This happens because the value injection happens after the class is fully constructed. This is why it is better to use the 3'rd option.

2. The @PropertySource annotation

<pre>@PropertySource("classpath:application.properties")

//env is an Environment variable
env.getProperty(configKey);</pre>

• PropertySouce sets values from the property source file in an Environment variable (in your class) when the class is loaded. So you able to fetch easily afterword.
  • Accessible through System Environment variable.

3. The @ConfigurationProperties annotation.

• This is mostly used in Spring projects to load configuration properties.

• It initializes an entity based on property data.

  • @ConfigurationProperties identifies the property file to load.
  • @Configuration creates a bean based on configuration file variables.

  @ConfigurationProperties(prefix = "user")
  @Configuration("UserData")
  class user {
    //Property & their getter / setter
  }
  
  @Autowired
  private UserData userData;
  
  userData.getPropertyName();

This might serve as a good starting point for moving/rotating/zooming a camera with mouse/trackpad (in typescript):

class CameraControl {
    zoomMode: boolean = false
    press: boolean = false
    sensitivity: number = 0.02

    constructor(renderer: Three.Renderer, public camera: Three.PerspectiveCamera, updateCallback:() => void){
        renderer.domElement.addEventListener('mousemove', event => {
            if(!this.press){ return }

            if(event.button == 0){
                camera.position.y -= event.movementY * this.sensitivity
                camera.position.x -= event.movementX * this.sensitivity        
            } else if(event.button == 2){
                camera.quaternion.y -= event.movementX * this.sensitivity/10
                camera.quaternion.x -= event.movementY * this.sensitivity/10
            }

            updateCallback()
        })    

        renderer.domElement.addEventListener('mousedown', () => { this.press = true })
        renderer.domElement.addEventListener('mouseup', () => { this.press = false })
        renderer.domElement.addEventListener('mouseleave', () => { this.press = false })

        document.addEventListener('keydown', event => {
            if(event.key == 'Shift'){
                this.zoomMode = true
            }
        })

        document.addEventListener('keyup', event => {
            if(event.key == 'Shift'){
                this.zoomMode = false
            }
        })

        renderer.domElement.addEventListener('mousewheel', event => {
            if(this.zoomMode){ 
                camera.fov += event.wheelDelta * this.sensitivity
                camera.updateProjectionMatrix()
            } else {
                camera.position.z += event.wheelDelta * this.sensitivity
            }

            updateCallback()
        })
    }
}

drop it in like:

this.cameraControl = new CameraControl(renderer, camera, () => {
    // you might want to rerender on camera update if you are not rerendering all the time
    window.requestAnimationFrame(() => renderer.render(scene, camera))
})

Controls:

• move while [holding mouse left / single finger on trackpad] to move camera in x/y plane
• move [mouse wheel / two fingers on trackpad] to move up/down in z-direction
• hold shift + [mouse wheel / two fingers on trackpad] to zoom in/out via increasing/decreasing field-of-view
• move while holding [mouse right / two fingers on trackpad] to rotate the camera (quaternion)

Additionally:

If you want to kinda zoom by changing the 'distance' (along yz) instead of changing field-of-view you can bump up/down camera's position y and z while keeping the ratio of position's y and z unchanged like:

// in mousewheel event listener in zoom mode
const ratio = camera.position.y / camera.position.z
camera.position.y += (event.wheelDelta * this.sensitivity * ratio)
camera.position.z += (event.wheelDelta * this.sensitivity)

You want getActivity() inside your class. It's better to use

yourclassname.this.getActivity()

Try this. It's helpful for you.

A little late to the party, but I think this does the trick:

mkdir YourRepo
cd YourRepo
git init --bare .git                       # create a bare repo
git remote add origin REMOTE_URL           # add a remote
git fetch origin refs/heads/*:refs/heads/* # fetch heads
git fetch origin refs/tags/*:refs/tags/*   # fetch tags
git init                                   # reinit work tree
git checkout master                        # checkout a branch

If this does something undesirable, I'd love to know. However, so far, this works for me.

Here is how I solved this on ubuntu 18:

1. $ sudo docker ps -a
2. copy the container ID

For each container do:

3. $ sudo docker stop container_ID
4. $ sudo docker rm container_ID

Error 127 means one of two things:

1. file not found: the path you're using is incorrect. double check that the program is actually in your $PATH, or in this case, the relative path is correct -- remember that the current working directory for a random terminal might not be the same for the IDE you're using. it might be better to just use an absolute path instead.
2. ldso is not found: you're using a pre-compiled binary and it wants an interpreter that isn't on your system. maybe you're using an x86_64 (64-bit) distro, but the prebuilt is for x86 (32-bit). you can determine whether this is the answer by opening a terminal and attempting to execute it directly. or by running file -L on /bin/sh (to get your default/native format) and on the compiler itself (to see what format it is).

if the problem is (2), then you can solve it in a few diff ways:

1. get a better binary. talk to the vendor that gave you the toolchain and ask them for one that doesn't suck.
2. see if your distro can install the multilib set of files. most x86_64 64-bit distros allow you to install x86 32-bit libraries in parallel.
3. build your own cross-compiler using something like crosstool-ng.
4. you could switch between an x86_64 & x86 install, but that seems a bit drastic ;).

In JavaScript 1.8.5, Object.getOwnPropertyNames returns an array of all properties found directly upon a given object.

Object.getOwnPropertyNames ( obj )

and another method Object.keys, which returns an array containing the names of all of the given object's own enumerable properties.

Object.keys( obj )

I used forEach to list values and keys in obj, same as for (var key in obj) ..

Object.keys(obj).forEach(function (key) {
      console.log( key , obj[key] );
});

This all are new features in ECMAScript , the mothods getOwnPropertyNames, keys won't supports old browser's.

You might want to look into this C# function to escape the string:

http://www.aspcode.net/C-encode-a-string-for-JSON-JavaScript.aspx

public static string Enquote(string s)  
{ 
    if (s == null || s.Length == 0)  
    { 
        return "\"\""; 
    } 
    char         c; 
    int          i; 
    int          len = s.Length; 
    StringBuilder sb = new StringBuilder(len + 4); 
    string       t; 

    sb.Append('"'); 
    for (i = 0; i < len; i += 1)  
    { 
        c = s[i]; 
        if ((c == '\\') || (c == '"') || (c == '>')) 
        { 
            sb.Append('\\'); 
            sb.Append(c); 
        } 
        else if (c == '\b') 
            sb.Append("\\b"); 
        else if (c == '\t') 
            sb.Append("\\t"); 
        else if (c == '\n') 
            sb.Append("\\n"); 
        else if (c == '\f') 
            sb.Append("\\f"); 
        else if (c == '\r') 
            sb.Append("\\r"); 
        else 
        { 
            if (c < ' ')  
            { 
                //t = "000" + Integer.toHexString(c); 
                string t = new string(c,1); 
                t = "000" + int.Parse(tmp,System.Globalization.NumberStyles.HexNumber); 
                sb.Append("\\u" + t.Substring(t.Length - 4)); 
            }  
            else  
            { 
                sb.Append(c); 
            } 
        } 
    } 
    sb.Append('"'); 
    return sb.ToString(); 
} 

http://www.quirksmode.org/js/cookies.html

update would just be resetting it using createCookie

function createCookie(name,value,days) {
    if (days) {
        var date = new Date();
        date.setTime(date.getTime() + (days * 24 * 60 * 60 *1000));
        var expires = "; expires=" + date.toGMTString();
    } else {
        var expires = "";
    }
    document.cookie = name + "=" + value + expires + "; path=/";
}

function readCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {
        var c = ca[i];
        while (c.charAt(0)==' ') {
            c = c.substring(1,c.length);
        }
        if (c.indexOf(nameEQ) == 0) {
            return c.substring(nameEQ.length,c.length);
        }
    }
    return null;
}

function eraseCookie(name) {
    createCookie(name,"",-1);
}

If you're putting this in a string within a program, you may actually need to use four backslashes (because the string parser will remove two of them when "de-escaping" it for the string, and then the regex needs two for an escaped regex backslash).

For instance:

regex("\\\\")

is interpreted as...

regex("\\" [escaped backslash] followed by "\\" [escaped backslash])

is interpreted as...

regex(\\)

is interpreted as a regex that matches a single backslash.

Depending on the language, you might be able to use a different form of quoting that doesn't parse escape sequences to avoid having to use as many - for instance, in Python:

re.compile(r'\\')

The r in front of the quotes makes it a raw string which doesn't parse backslash escapes.

I ran into a similar issue. I deleted these:

• libraries and caches from the .idea folder ( YourApp > .idea > .. ) AND

• contents of the build folder.

  then rebuild.

* DON'T FORGET TO BACKUP YOUR PROJECT FIRST *

In Swift 2.0 assuming func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool {:

var oldString = textfield.text!
let newRange = oldString.startIndex.advancedBy(range.location)..<oldString.startIndex.advancedBy(range.location + range.length)
let newString = oldString.stringByReplacingCharactersInRange(newRange, withString: string)

There can be several reasons. Most of the times it may be some of the below reasons ,

1. You have deleted some of the .jar files from your /lib folder
2. You have added new .jar files
3. you have added new .jar files which may be conflict with others

So what to do is we have to resolve those missing / updating / newly_added jar files.

1. right click on the project and go to properties
2. Select Java Build Path
3. go to the Libraries tab
4. Remove the jar file references which you have removed already. There will be a red mark near them so you can identify them easily.
5. Add the references to the newly added .jar files by using Add JARs
6. Refresh the project

This will solve the problem if it's because one of the above reasons.

Taken from this answer.

1. Close your packages.config file.
2. Build
3. Warning is gone!

This is the first time I see ignoring a problem actually makes it go away...

Edit in 2020: if you are viewing this warning, consider upgrading to PackageReference if you can

The following solution worked for me.

I added resetting state function to meta reducers.The key was to use

return reducer(undefined, action);

to set all reducers to initial state. Returning undefined instead was causing errors due to the fact that the structure of the store has been destroyed.

/reducers/index.ts

export function resetState(reducer: ActionReducer<State>): ActionReducer<State> {
  return function (state: State, action: Action): State {

    switch (action.type) {
      case AuthActionTypes.Logout: {
        return reducer(undefined, action);
      }
      default: {
        return reducer(state, action);
      }
    }
  };
}

export const metaReducers: MetaReducer<State>[] = [ resetState ];

app.module.ts

import { StoreModule } from '@ngrx/store';
import { metaReducers, reducers } from './reducers';

@NgModule({
  imports: [
    StoreModule.forRoot(reducers, { metaReducers })
  ]
})
export class AppModule {}

Unfortunately SQL Server interprets the quoted comma as a delimiter. This applies to both BCP and bulk insert .

From http://msdn.microsoft.com/en-us/library/ms191485%28v=sql.100%29.aspx

If a terminator character occurs within the data, it is interpreted as a terminator, not as data, and the data after that character is interpreted as belonging to the next field or record. Therefore, choose your terminators carefully to make sure that they never appear in your data.

It does work indeed. Issue was with my less compiler. It was compiled in to:

.container {
  min-height: calc(-51vh);
}

Fixed with the following code in less file:

.container {
  min-height: calc(~"100vh - 150px");
}

Thanks to this link: Less Aggressive Compilation with CSS3 calc

In Spring applications, if you enable annotation based transaction support using <tx:annotation-driven/> and annotate any class/method with @Transactional(propagation=Propagation.REQUIRED) then Spring framework will start a transaction and executes the method and commits the transaction. If any RuntimeException occurred then the transaction will be rolled back.

Actually propagation=Propagation.REQUIRED is default propagation level, you don't need to explicitly mentioned it.

For further info : http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/transaction.html#transaction-declarative-annotations

The best option is to Change Application Settings from the Custom Site Delegation
Open IIS and from the root select Feature Delegation and then select Application Settings and from the right sidebar select Read/Write

The code formatting is available in Visual Studio Code through the following shortcuts:

• On Windows Shift + Alt + F
• On Mac Shift + Option + F
• On Linux Ctrl + Shift + I

Alternatively, you can find the shortcut, as well as other shortcuts, through the 'Command Palette' provided in the editor with Ctrl +Shift+ P (or Command + Shift + P on Mac), and then searching for format document.

For unsaved snippets

1. Open command palette (Win: F1 or Ctrt+Shift+P)

2. Find 'Change Language Model'

3. Select language e.g. json. By now syntax should be highlighted.

4. Format document (e.g. Open Command Palette -> 'Format Document')

Unformat

1. Select text
2. Command Palette -> Join Lines

Merge of Shubham's great answer and JJD use enum instead of string

               def startItem = '|  ', endItem = '  |'
               def repeatLength = startItem.length() + output.length() + endItem.length()
               println('\n' + ('-' * repeatLength) + '\n' + startItem + output + endItem + '\n' + ('-' * repeatLength))
           }
       }
   }
}

git config --global core.autocrlf false works well for global settings.

But if you are using Visual Studio, might also need to modify .gitattributes for some type of projects (e.g c# class library application):

• remove line * text=auto

The is not operator is preferred over negating the result of is for stylistic reasons. "if x is not None:" reads just like English, but "if not x is None:" requires understanding of the operator precedence and does not read like english.

If there is a performance difference my money is on is not, but this almost certainly isn't the motivation for the decision to prefer that technique. It would obviously be implementation-dependent. Since is isn't overridable, it should be easy to optimise out any distinction anyhow.

I recently came across a jQuery plugin which does what I originally wanted https://github.com/briangonzalez/jquery.adaptive-backgrounds.js in regards to getting a dominiate color from an image.

The problem is that arr is not (declared as) a 2D array, and you are treating it as if it were 2D.

You need to tell scp where to send the file. In your command that is not working:

scp C:\Users\Admin\Desktop\WMU\5260\A2.c ~

You have not mentioned a remote server. scp uses : to delimit the host and path, so it thinks you have asked it to download a file at the path \Users\Admin\Desktop\WMU\5260\A2.c from the host C to your local home directory.

The correct upload command, based on your comments, should be something like:

C:\> pscp C:\Users\Admin\Desktop\WMU\5260\A2.c [email protected]:

If you are running the command from your home directory, you can use a relative path:

C:\Users\Admin> pscp Desktop\WMU\5260\A2.c [email protected]:

You can also mention the directory where you want to this folder to be downloaded to at the remote server. i.e by just adding a path to the folder as below:

C:/> pscp C:\Users\Admin\Desktop\WMU\5260\A2.c [email protected]:/home/path_to_the_folder/

I have no idea what linux distribution "ubuntu centOS" is. Ubuntu and CentOS are two different distributions.

To answer the question in the header: To install make in ubuntu you have to install build-essentials

sudo apt-get install build-essential

I've been a big fan of REST in the past and it has many advantages over RPC on paper. You can present the client with different Content-Types, Caching, reuse of HTTP status codes, you can guide the client through the API and you can embed documentation in the API if it isn't mostly self-explaining anyway.

But my experience has been that in practice this doesn't hold up and instead you do a lot of unnecessary work to get everything right. Also the HTTP status codes often don't map to your domain logic exactly and using them in your context often feels a bit forced. But the worst thing about REST in my opinion is that you spend a lot of time to design your resources and the interactions they allow. And whenever you do some major additions to your API you hope you find a good solution to add the new functionality and you didn't design yourself into a corner already.

This often feels like a waste of time to me because most of the time I already have a perfectly fine and obvious idea about how to model an API as a set of remote procedure calls. And if I have gone through all this effort to model my problem inside the constraints of REST the next problem is how to call it from the client? Our programs are based on calling procedures so building a good RPC client library is easy, building a good REST client library not so much and in most cases you will just map back from your REST API on the server to a set of procedures in your client library.

Because of this, RPC feels a lot simpler and more natural to me today. What I really miss though is a consistent framework that makes it easy to write RPC services that are self-describing and interoperable. Therefore I created my own project to experiment with new ways to make RPC easier for myself and maybe somebody else finds it useful, too: https://github.com/aheck/reflectrpc

You have to set the associatedEmployee on the Vehicle before persisting the Employee.

Employee newEmployee = new Employee("matt");
vehicle1.setAssociatedEmployee(newEmployee);
vehicles.add(vehicle1);

newEmployee.setVehicles(vehicles);

Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);

This was my solution

#include <stdlib.h>
#include <stdarg.h>

char *strconcat(int num_args, ...) {
    int strsize = 0;
    va_list ap;
    va_start(ap, num_args);
    for (int i = 0; i < num_args; i++) 
        strsize += strlen(va_arg(ap, char*));

    char *res = malloc(strsize+1);
    strsize = 0;
    va_start(ap, num_args);
    for (int i = 0; i < num_args; i++) {
        char *s = va_arg(ap, char*);
        strcpy(res+strsize, s);
        strsize += strlen(s);
    }
    va_end(ap);
    res[strsize] = '\0';

    return res;
}

but you need to specify how many strings you're going to concatenate

char *str = strconcat(3, "testing ", "this ", "thing");

You can use the simple line shown below to append strings in one buffer:

sprintf(Buffer,"%s %s %s","Hello World","Good Morning","Good Afternoon");

The following will produce, in the output directory,

Penny's Spark 2 example is the way to do it in spark2. There's one more trick: have that header generated for you by doing an initial scan of the data, by setting the option inferSchema to true

Here, then, assumming that spark is a spark session you have set up, is the operation to load in the CSV index file of all the Landsat images which amazon host on S3.

val csvdata = spark.read.options(Map(
    "header" -> "true",
    "ignoreLeadingWhiteSpace" -> "true",
    "ignoreTrailingWhiteSpace" -> "true",

The bad news is: this triggers a scan through the file; for something large like this 20+MB zipped CSV file, that can take 30s over a long haul connection. Bear that in mind: you are better off manually coding up the schema once you've got it coming in.

I think in the question and in some of the answers there is a bit of confusion about the meaning of this pseudocode in DOS: IF A IF B X ELSE Y. It does not mean IF(A and B) THEN X ELSE Y, but in fact means IF A( IF B THEN X ELSE Y). If the test of A fails, then he whole of the inner if-else will be ignored.

As one of the answers mentioned, in this case only one of the tests can succeed so the 'else' is not needed, but of course that only works in this example, it isn't a general solution for doing if-else.

There are lots of ways around this. Here is a few ideas, all are quite ugly but hey, this is (or at least was) DOS!

@echo off

set one=1
set two=2

REM Example 1

IF %one%_%two%==1_1 (
   echo Example 1 fails
) ELSE IF %one%_%two%==1_2 (
   echo Example 1 works correctly
) ELSE (
    echo Example 1 fails
)

REM Example 2

set test1result=0
set test2result=0

if %one%==1 if %two%==1 set test1result=1
if %one%==1 if %two%==2 set test2result=1

IF %test1result%==1 (
   echo Example 2 fails
) ELSE IF %test2result%==1 (
   echo Example 2 works correctly
) ELSE (
    echo Example 2 fails
)

REM Example 3

if %one%==1 if %two%==1 (
   echo Example 3 fails
   goto :endoftests
)
if %one%==1 if %two%==2 (
   echo Example 3 works correctly
   goto :endoftests
)
echo Example 3 fails
)
:endoftests

You can always create a new page and use phpinfo(). Scroll down to the curl section and see if it is enabled.

How about this, it will read each line to a variable and that can be used subsequently ! say myscript output is redirected to a file called myscript_output

awk '{while ( (getline var < "myscript_output") >0){print var;} close ("myscript_output");}'

In the case that you want to revert a file to a previous commit (and the file you want to revert already committed) you can use

git checkout HEAD^1 path/to/file

or

git checkout HEAD~1 path/to/file

Then just stage and commit the "new" version.

Armed with the knowledge that a commit can have two parents in the case of a merge, you should know that HEAD^1 is the first parent and HEAD~1 is the second parent.

Either will work if there is only one parent in the tree.

Two solutions for this error:

1. add this permission in your androidManifest.xml of your Android project

<uses-permission android:name="android.permission.INTERNET"/>

2. Turn on the Internet Connection of your device first.

I think you can achieve it by using the below code

Model::get(['ColumnName'])->toArray();

There is no my.cnf by default. As such, MySQL starts with all of the default settings. If you want to create your own my.cnf to override any defaults, place it at /etc/my.cnf.

Also, you can run mysql --help and look through it for the conf locations listed.

Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf 
The following groups are read: mysql client
The following options may be given as the first argument:
--print-defaults        Print the program argument list and exit.
--no-defaults           Don't read default options from any option file.
--defaults-file=#       Only read default options from the given file #.
--defaults-extra-file=# Read this file after the global files are read.

As you can see, there are also some options for bypassing the conf files, or specifying other files to read when you invoke mysql on the command line.

I'd say that generally every fundamentalism leads to hell.

You certainly wouldn't want to end up with exception driven flow, but avoiding exceptions altogether is also a bad idea. You have to find a balance between both approaches. What I would not do is to create an exception type for every exceptional situation. That is not productive.

What I generally prefer is to create two basic types of exceptions which are used throughout the system: LogicalException and TechnicalException. These can be further distinguished by subtypes if needed, but it is not generally not necessary.

The technical exception denotes the really unexpected exception like database server being down, the connection to the web service threw the IOException and so on.

On the other hand the logical exceptions are used to propagate the less severe erroneous situation to the upper layers (generally some validation result).

Please note that even the logical exception is not intended to be used on regular basis to control the program flow, but rather to highlight the situation when the flow should really end. When used in Java, both exception types are RuntimeException subclasses and error handling is highly aspect oriented.

So in the login example it might be wise to create something like AuthenticationException and distinguish the concrete situations by enum values like UsernameNotExisting, PasswordMismatch etc. Then you won't end up in having a huge exception hierarchy and can keep the catch blocks on maintainable level. You can also easily employ some generic exception handling mechanism since you have the exceptions categorized and know pretty well what to propagate up to the user and how.

Our typical usage is to throw the LogicalException during the Web Service call when the user's input was invalid. The Exception gets marshalled to the SOAPFault detail and then gets unmarshalled to the exception again on the client which is resulting in showing the validation error on one certain web page input field since the exception has proper mapping to that field.

This is certainly not the only situation: you don't need to hit web service to throw up the exception. You are free to do so in any exceptional situation (like in the case you need to fail-fast) - it is all at your discretion.

It's O(V+E) because each visit to v of V must visit each e of E where |e| <= V-1. Since there are V visits to v of V then that is O(V). Now you have to add V * |e| = E => O(E). So total time complexity is O(V + E).

void foo<TOne, TTwo>() 
   where TOne : BaseOne
   where TTwo : BaseTwo

You can use this method to create hidden text field with/without form. If you need form just pass form with object status = true.

You can also add multiple hidden fields. Use this way:

        {
            'fieldinFORM' : 'thisdata201' , 
            'fieldinFORM2' : 'this3' //multiple hidden fields
            .
            .
            .
            .
            .
            'nNoOfFields' : 'nthData'
        },
    "form" : 
    {

Only if the other application is designed to allow it, by providing components for you to add into your own application.

I got this to work to scroll to the bottom of a ScrollView (with a TextView inside):

(I put this on a method that updates the TextView)

final ScrollView myScrollView = (ScrollView) findViewById(R.id.myScroller);
    myScrollView.post(new Runnable() {
    public void run() {
        myScrollView.fullScroll(View.FOCUS_DOWN);
    }
});

In general Tight Coupling is bad in but most of the time, because it reduces flexibility and re-usability of code, it makes changes much more difficult, it impedes testability etc.

Tightly Coupled Object is an object need to know quite a bit about each other and are usually highly dependent on each other interfaces. Changing one object in a tightly coupled application often requires changes to a number of other objects, In small application we can easily identify the changes and there is less chance to miss anything. But in large applications these inter-dependencies are not always known by every programmer or chance is there to miss changes. But each set of loosely coupled objects are not dependent on others.

In short we can say, loose coupling is a design goal that seeks to reduce the interdependencies between components of a system with the goal of reducing the risk that changes in one component will require changes in any other component. Loose coupling is a much more generic concept intended to increase the flexibility of a system, make it more maintainable, and make the entire framework more 'stable'.

Coupling refers to the degree of direct knowledge that one element has of another. we can say an eg: A and B, only B change its behavior only when A change its behavior. A loosely coupled system can be easily broken down into definable elements.

Here's the config for ISAPI_Rewrite 3:

RewriteBase /

RewriteCond %{HTTP_HOST} ^mysite.org.uk$ [NC]

RewriteRule ^stuff/(.+)$ http://stuff.mysite.org.uk/$1 [NC,R=301,L]

You can select to an anonymous type, for example

var dataset2 = 
    (from recordset in entities.processlists 
    where recordset.ProcessName == processname 
    select new
    {
        serverName = recordset.ServerName,
        processId = recordset.ProcessID, 
        username = recordset.Username
    }).ToList();

Or you can create a new class that will represent your selection, for example

public class MyDataSet
{
    public string ServerName { get; set; }
    public string ProcessId { get; set; }
    public string Username { get; set; }
}

then you can for example do the following

 var dataset2 = 
    (from recordset in entities.processlists 
    where recordset.ProcessName == processname 
    select new MyDataSet
    {
        ServerName = recordset.ServerName,
        ProcessId = recordset.ProcessID, 
        Username = recordset.Username
    }).ToList();

Looks like this is on the bottom left now as an icon with overlapping windows and the "Undock into separate window." tooltip.

If you intend to change A, B, C.... you see high above the columns, you can not. You can hide A, B, C...: Button Office(top left) Excel Options(bottom) Advanced(left) Right looking: Display options fot this worksheet: Select the worksheet(eg. Sheet3) Uncheck: Show column and row headers Ok

If you are using Visual Studio, You probably are trying to execute the application in the Release Mode, try changing it to the Debug Mode.

You can use long type or Int64

As mentioned by Zeeshan, the logrotate options size, minsize, maxsize are triggers for rotation.

To better explain it. You can run logrotate as often as you like, but unless a threshold is reached such as the filesize being reached or the appropriate time passed, the logs will not be rotated.

The size options do not ensure that your rotated logs are also of the specified size. To get them to be close to the specified size you need to call the logrotate program sufficiently often. This is critical.

For log files that build up very quickly (e.g. in the hundreds of MB a day), unless you want them to be very large you will need to ensure logrotate is called often! this is critical.

Therefore to stop your disk filling up with multi-gigabyte log files you need to ensure logrotate is called often enough, otherwise the log rotation will not work as well as you want.

on Ubuntu, you can easily switch to hourly rotation by moving the script /etc/cron.daily/logrotate to /etc/cron.hourly/logrotate

Or add

*/5 * * * * /etc/cron.daily/logrotate 

To your /etc/crontab file. To run it every 5 minutes.

The size option ignores the daily, weekly, monthly time options. But minsize & maxsize take it into account.

The man page is a little confusing there. Here's my explanation.

minsize rotates only when the file has reached an appropriate size and the set time period has passed. e.g. minsize 50MB + daily If file reaches 50MB before daily time ticked over, it'll keep growing until the next day.

maxsize will rotate when the log reaches a set size or the appropriate time has passed. e.g. maxsize 50MB + daily. If file is 50MB and we're not at the next day yet, the log will be rotated. If the file is only 20MB and we roll over to the next day then the file will be rotated.

size will rotate when the log > size. Regardless of whether hourly/daily/weekly/monthly is specified. So if you have size 100M - it means when your log file is > 100M the log will be rotated if logrotate is run when this condition is true. Once it's rotated, the main log will be 0, and a subsequent run will do nothing.

So in the op's case. Specficially 50MB max I'd use something like the following:

/var/log/logpath/*.log {
    maxsize 50M
    hourly
    missingok
    rotate 8
    compress
    notifempty
    nocreate
}

Which means he'd create 8hrs of logs max. And there would be 8 of them at no more than 50MB each. Since he's saying that he's getting multi gigabytes each day and assuming they build up at a fairly constant rate, and maxsize is used he'll end up with around close to the max reached for each file. So they will be likely close to 50MB each. Given the volume they build, he would need to ensure that logrotate is run often enough to meet the target size.

Since I've put hourly there, we'd need logrotate to be run a minimum of every hour. But since they build up to say 2 gigabytes per day and we want 50MB... assuming a constant rate that's 83MB per hour. So you can imagine if we run logrotate every hour, despite setting maxsize to 50 we'll end up with 83MB log's in that case. So in this instance set the running to every 30 minutes or less should be sufficient.

Ensure logrotate is run every 30 mins.

per @dantheta's comment:

As of npm 1.1.65, Github URL can be more concise user/project. npmjs.org/doc/files/package.json.html You can attach the branch like user/project#branch

So

"babel-eslint": "babel/babel-eslint",

Or for tag v1.12.0 on jscs:

"jscs": "jscs-dev/node-jscs#v1.12.0",

Note, if you use npm --save, you'll get the longer git

From https://docs.npmjs.com/cli/v6/configuring-npm/package-json#git-urls-as-dependencies

Git URLs as Dependencies

Git urls are of the form:

git+ssh://[email protected]:npm/cli.git#v1.0.27 git+ssh://[email protected]:npm/cli#semver:^5.0 git+https://[email protected]/npm/cli.git
git://github.com/npm/cli.git#v1.0.27

If #<commit-ish> is provided, it will be used to clone exactly that commit. If > the commit-ish has the format #semver:<semver>, <semver> can be any valid semver range or exact version, and npm will look for any tags or refs matching that range in the remote repository, much as it would for a registry dependency. If neither #<commit-ish> or #semver:<semver> is specified, then master is used.

GitHub URLs

As of version 1.1.65, you can refer to GitHub urls as just "foo": "user/foo-project". Just as with git URLs, a commit-ish suffix can be included. For example:

{
 "name": "foo",
 "version": "0.0.0",
 "dependencies": {
   "express": "expressjs/express",
   "mocha": "mochajs/mocha#4727d357ea",
   "module": "user/repo#feature\/branch"
 }
}```

Use:

Response.Redirect(Request.RawUrl, true);

The best solution for this is to create a simple parent pom file project (with packaging 'pom') generically for all projects from your organization.

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>your.company</groupId>
    <artifactId>company-parent</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>pom</packaging>

    <distributionManagement>
        <repository>
            <id>nexus-site</id>
            <url>http://central_nexus/server</url>
        </repository>
    </distributionManagement>

</project>

This can be built, released, and deployed to your local nexus so everyone has access to its artifact.

Now for all projects which you wish to use it, simply include this section:

<parent>
  <groupId>your.company</groupId>
  <artifactId>company-parent</artifactId>
  <version>1.0.0</version>
</parent>

This solution will allow you to easily add other common things to all your company's projects. For instance if you wanted to standardize your JUnit usage to a specific version, this would be the perfect place for that.

If you have projects that use multi-module structures that have their own parent, Maven also supports chaining inheritance so it is perfectly acceptable to make your project's parent pom file refer to your company's parent pom and have the project's child modules not even aware of your company's parent.

I see from your example project structure that you are attempting to put your parent project at the same level as your aggregator pom. If your project needs its own parent, the best approach I have found is to include the parent at the same level as the rest of the modules and have your aggregator pom.xml file at the root of where all your modules' directories exist.

- pom.xml (aggregator)
    - project-parent
    - project-module1
    - project-module2

What you do with this structure is include your parent module in the aggregator and build everything with a mvn install from the root directory.

We use this exact solution at my organization and it has stood the test of time and worked quite well for us.

According to the pytest docs, pytest --capture=sys should work. If you want to capture standard out inside a test, refer to the capsys fixture.

Yep, you'll want to do something like this:

echo -n "Enter Fullname: " 
read fullname

Another option would be to have them supply this information on the command line. Getopts is your best bet there.

Followed Stephen's advice and tried to debug the code and whoa! it worked. The answer lies in the debug message itself.

Will attempt to recover by breaking constraint NSLayoutConstraint:0x191f0920 H:[MPKnockoutButton:0x17a876b0]-(34)-[MPDetailSlider:0x17a8bc50](LTR)>

The line above tells you that the runtime worked by removing this constraint. May be you don't need Horizontal Spacing on your button (MPKnockoutButton). Once you clear this constraint, it won't complain at runtime & you would get the desired behaviour.

I checked again http://localhost/phpmyadmin/

Mysqli said:

"phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server."

I'm opening again config.inc.php and I found

$cfg['Servers'][$i]['password'] =

Fill the password with your password

It worked for me. It may work for you too.

You can use the extra arguments to setTimeout to pass parameters to the callback function.

for (var i = 1; i <= 2; i++) {
    setTimeout(function(j) { alert(j) }, 100, i);
}

Note: This doesn't work on IE9 and below browsers.

Things seems a little confused in the code in your question, so I am going to give you an example of what I think you are try to do.

First considerations are about mixing HTML, Javascript and CSS:

Why is using onClick() in HTML a bad practice?

Unobtrusive Javascript

Inline Styles vs Classes

I will be removing inline content and splitting these into their appropriate files.

Next, I am going to go with the "click" event and displose of the "change" event, as it is not clear that you want or need both.

Your function changeBackground sets both the backround color and the text color to the same value (your text will not be seen), so I am caching the color value as we don't need to look it up in the DOM twice.

CSS

#TheForm {
    margin-left: 396px;
}
#submitColor {
    margin-left: 48px;
    margin-top: 5px;
}

HTML

<form id="TheForm">
    <input id="color" type="text" />
    <br/>
    <input id="submitColor" value="Submit" type="button" />
</form>
<span id="coltext">This text should have the same color as you put in the text box</span>

Javascript

function changeBackground() {
    var color = document.getElementById("color").value; // cached

    // The working function for changing background color.
    document.bgColor = color;

    // The code I'd like to use for changing the text simultaneously - however it does not work.
    document.getElementById("coltext").style.color = color;
}

document.getElementById("submitColor").addEventListener("click", changeBackground, false);

Color Values

CSS colors are defined using a hexadecimal (hex) notation for the combination of Red, Green, and Blue color values (RGB). The lowest value that can be given to one of the light sources is 0 (hex 00). The highest value is 255 (hex FF).

Hex values are written as 3 double digit numbers, starting with a # sign.

Update: as pointed out by @Ian

Hex can be either 3 or 6 characters long

Source: W3C

Numerical color values

The format of an RGB value in hexadecimal notation is a ‘#’ immediately followed by either three or six hexadecimal characters. The three-digit RGB notation (#rgb) is converted into six-digit form (#rrggbb) by replicating digits, not by adding zeros. For example, #fb0 expands to #ffbb00. This ensures that white (#ffffff) can be specified with the short notation (#fff) and removes any dependencies on the color depth of the display.

Here is an alternative function that will check that your input is a valid CSS Hex Color, it will set the text color only or throw an alert if it is not valid.

For regex testing, I will use this pattern

/^#(?:[0-9a-f]{3}){1,2}$/i

but if you were regex matching and wanted to break the numbers into groups then you would require a different pattern

function changeBackground() {
    var color = document.getElementById("color").value.trim(),
        rxValidHex = /^#(?:[0-9a-f]{3}){1,2}$/i;

    if (rxValidHex.test(color)) {
        document.getElementById("coltext").style.color = color;
    } else {
        alert("Invalid CSS Hex Color");
    }
}

document.getElementById("submitColor").addEventListener("click", changeBackground, false);

On jsfiddle

Here is a further modification that will allow colours by name along with by hex.

function changeBackground() {
    var names = ["AliceBlue", "AntiqueWhite", "Aqua", "Aquamarine", "Azure", "Beige", "Bisque", "Black", "BlanchedAlmond", "Blue", "BlueViolet", "Brown", "BurlyWood", "CadetBlue", "Chartreuse", "Chocolate", "Coral", "CornflowerBlue", "Cornsilk", "Crimson", "Cyan", "DarkBlue", "DarkCyan", "DarkGoldenRod", "DarkGray", "DarkGrey", "DarkGreen", "DarkKhaki", "DarkMagenta", "DarkOliveGreen", "Darkorange", "DarkOrchid", "DarkRed", "DarkSalmon", "DarkSeaGreen", "DarkSlateBlue", "DarkSlateGray", "DarkSlateGrey", "DarkTurquoise", "DarkViolet", "DeepPink", "DeepSkyBlue", "DimGray", "DimGrey", "DodgerBlue", "FireBrick", "FloralWhite", "ForestGreen", "Fuchsia", "Gainsboro", "GhostWhite", "Gold", "GoldenRod", "Gray", "Grey", "Green", "GreenYellow", "HoneyDew", "HotPink", "IndianRed", "Indigo", "Ivory", "Khaki", "Lavender", "LavenderBlush", "LawnGreen", "LemonChiffon", "LightBlue", "LightCoral", "LightCyan", "LightGoldenRodYellow", "LightGray", "LightGrey", "LightGreen", "LightPink", "LightSalmon", "LightSeaGreen", "LightSkyBlue", "LightSlateGray", "LightSlateGrey", "LightSteelBlue", "LightYellow", "Lime", "LimeGreen", "Linen", "Magenta", "Maroon", "MediumAquaMarine", "MediumBlue", "MediumOrchid", "MediumPurple", "MediumSeaGreen", "MediumSlateBlue", "MediumSpringGreen", "MediumTurquoise", "MediumVioletRed", "MidnightBlue", "MintCream", "MistyRose", "Moccasin", "NavajoWhite", "Navy", "OldLace", "Olive", "OliveDrab", "Orange", "OrangeRed", "Orchid", "PaleGoldenRod", "PaleGreen", "PaleTurquoise", "PaleVioletRed", "PapayaWhip", "PeachPuff", "Peru", "Pink", "Plum", "PowderBlue", "Purple", "Red", "RosyBrown", "RoyalBlue", "SaddleBrown", "Salmon", "SandyBrown", "SeaGreen", "SeaShell", "Sienna", "Silver", "SkyBlue", "SlateBlue", "SlateGray", "SlateGrey", "Snow", "SpringGreen", "SteelBlue", "Tan", "Teal", "Thistle", "Tomato", "Turquoise", "Violet", "Wheat", "White", "WhiteSmoke", "Yellow", "YellowGreen"],
        color = document.getElementById("color").value.trim(),
        rxValidHex = /^#(?:[0-9a-f]{3}){1,2}$/i,
        formattedName = color.charAt(0).toUpperCase() + color.slice(1).toLowerCase();

    if (names.indexOf(formattedName) !== -1 || rxValidHex.test(color)) {
        document.getElementById("coltext").style.color = color;
    } else {
        alert("Invalid CSS Color");
    }
}

document.getElementById("submitColor").addEventListener("click", changeBackground, false);

You do not want to wait too long before the element changes. In this code the webdriver waits for up to 2 seconds before it continues.

WebDriverWait wait = new WebDriverWait(driver, TimeSpan.FromMilliseconds(2000));
wait.Until(ExpectedConditions.VisibilityOfAllElementsLocatedBy(By.Name("html-name")));

The problem might be with service mysql-server and apache2 running while system start. You can do the following.

sudo /opt/lampp/lampp stop

To stop already running default services

sudo service apache2 stop
sudo service mysql  stop

To remove the services completely, so that they won't create problem in next system-restart, If you are in ubuntu(debian)

sudo apt-get remove apache2
sudo apt-get remove mysql-server

If you are in redhat or other, You could use yum or similar command to uninstall the services

Then start the lampp again

sudo /opt/lampp/lampp start

Also, don't install mysql-server in the system, because it might start in system start-up, occupy the port, and create problem for mysql of lampp.

Actually awk is exactly the tool you should be looking into:

ps axu | grep '[j]boss' | awk '{print $5}'

or you can ditch the grep altogether since awk knows about regular expressions:

ps axu | awk '/[j]boss/ {print $5}'

But if, for some bizarre reason, you really can't use awk, there are other simpler things you can do, like collapse all whitespace to a single space first:

ps axu | grep '[j]boss' | sed 's/\s\s*/ /g' | cut -d' ' -f5

That grep trick, by the way, is a neat way to only get the jboss processes and not the grep jboss one (ditto for the awk variant as well).

The grep process will have a literal grep [j]boss in its process command so will not be caught by the grep itself, which is looking for the character class [j] followed by boss.

This is a nifty way to avoid the | grep xyz | grep -v grep paradigm that some people use.

Try this

in view:

<form name="formName" ng-submit="submitForm(formName)">
 <!-- fields -->
</form>

in controller:

$scope.submitForm = function(form){
  if(form.$valid) {
   // Code here if valid
  }
};

or

in view:

<form name="formName" ng-submit="submitForm(formName.$valid)">
  <!-- fields -->
</form>

in controller:

$scope.submitForm = function(formValid){
  if(formValid) {
    // Code here if valid
  }
};

What is embedded bitcode?

According to docs:

Bitcode is an intermediate representation of a compiled program. Apps you upload to iTunes Connect that contain bitcode will be compiled and linked on the App Store. Including bitcode will allow Apple to re-optimize your app binary in the future without the need to submit a new version of your app to the store.

Update: This phrase in "New Features in Xcode 7" made me to think for a long time that Bitcode is needed for Slicing to reduce app size:

When you archive for submission to the App Store, Xcode will compile your app into an intermediate representation. The App Store will then compile the bitcode down into the 64 or 32 bit executables as necessary.

However that's not true, Bitcode and Slicing work independently: Slicing is about reducing app size and generating app bundle variants, and Bitcode is about certain binary optimizations. I've verified this by checking included architectures in executables of non-bitcode apps and founding that they only include necessary ones.

Bitcode allows other App Thinning component called Slicing to generate app bundle variants with particular executables for particular architectures, e.g. iPhone 5S variant will include only arm64 executable, iPad Mini armv7 and so on.

When to enable ENABLE_BITCODE in new Xcode?

For iOS apps, bitcode is the default, but optional. If you provide bitcode, all apps and frameworks in the app bundle need to include bitcode. For watchOS and tvOS apps, bitcode is required.

What happens to the binary when ENABLE_BITCODE is enabled in the new Xcode?

From Xcode 7 reference:

Activating this setting indicates that the target or project should generate bitcode during compilation for platforms and architectures which support it. For Archive builds, bitcode will be generated in the linked binary for submission to the app store. For other builds, the compiler and linker will check whether the code complies with the requirements for bitcode generation, but will not generate actual bitcode.

Here's a couple of links that will help in deeper understanding of Bitcode:

• Bitcode Demystified
• Why I'm not enabling Bitcode

To add on to Ken's answer, this handles commas and spaces and parentheses

As everyone else has said, @require only gets run when the script has installed. However, you should note as well that currently jQuery 1.4.* doesn't work with greasemonkey. You can see here for details: http://forum.jquery.com/topic/importing-jquery-1-4-1-into-greasemonkey-scripts-generates-an-error

You will have to use jQuery 1.3.2 until things change.

Use the put method: https://developer.android.com/reference/org/json/JSONObject.html

JSONObject person =  jsonArray.getJSONObject(0).getJSONObject("person");
person.put("name", "Sammie");

For Maven based projects you need a dependency.

Function for moving files:

private void moveFile(File file, File dir) throws IOException {
    File newFile = new File(dir, file.getName());
    FileChannel outputChannel = null;
    FileChannel inputChannel = null;
    try {
        outputChannel = new FileOutputStream(newFile).getChannel();
        inputChannel = new FileInputStream(file).getChannel();
        inputChannel.transferTo(0, inputChannel.size(), outputChannel);
        inputChannel.close();
        file.delete();
    } finally {
        if (inputChannel != null) inputChannel.close();
        if (outputChannel != null) outputChannel.close();
    }

}

This is my approach to enums in Ruby. I was going for short and sweet, not necessarily the the most C-like. Any thoughts?

module Kernel
  def enum(values)
    Module.new do |mod|
      values.each_with_index{ |v,i| mod.const_set(v.to_s.capitalize, 2**i) }

      def mod.inspect
        "#{self.name} {#{self.constants.join(', ')}}"
      end
    end
  end
end

States = enum %w(Draft Published Trashed)
=> States {Draft, Published, Trashed} 

States::Draft
=> 1

States::Published
=> 2

States::Trashed
=> 4

States::Draft | States::Trashed
=> 5

I found this solution by Sebastian Ekström. It's quick, dirty, and works really well. Even if you don't know the parent's height:

.element {
  position: relative;
  top: 50%;
  -webkit-transform: translateY(-50%);
  -ms-transform: translateY(-50%);
  transform: translateY(-50%);
}

Read the full article here.

Here is one example that worked for me.

find <mainfolder path> -name '*myfiles.java' | xargs -n 1 basename

yes you can, but you need to use aux routing. you will need to give a name to your router-outlet:

<router-outlet name="auxPathName"></router-outlet>

and setup your route config:

@RouteConfig([
  {path:'/', name: 'RetularPath', component: OneComponent, useAsDefault: true},
  {aux:'/auxRoute', name: 'AuxPath', component: SecondComponent}
])

Check out this example, and also this video.

Update for RC.5 Aux routes has changed a bit: in your router outlet use a name:

<router-outlet name="aux">

In your router config:

{path: '/auxRouter', component: secondComponentComponent, outlet: 'aux'}

The following code works fine:

@using (Html.BeginForm("Upload", "Upload", FormMethod.Post, 
                                      new { enctype = "multipart/form-data" }))
{
    @Html.ValidationSummary(true)
    <fieldset>
        Select a file <input type="file" name="file" />
        <input type="submit" value="Upload" />
    </fieldset>
}

and generates as expected:

<form action="/Upload/Upload" enctype="multipart/form-data" method="post">    
    <fieldset>
        Select a file <input type="file" name="file" />
        <input type="submit" value="Upload" />
    </fieldset>
</form>

On the other hand if you are writing this code inside the context of other server side construct such as an if or foreach you should remove the @ before the using. For example:

@if (SomeCondition)
{
    using (Html.BeginForm("Upload", "Upload", FormMethod.Post, 
                                      new { enctype = "multipart/form-data" }))
    {
        @Html.ValidationSummary(true)
        <fieldset>
            Select a file <input type="file" name="file" />
            <input type="submit" value="Upload" />
        </fieldset>
    }
}

As far as your server side code is concerned, here's how to proceed:

[HttpPost]
public ActionResult Upload(HttpPostedFileBase file) 
{
    if (file != null && file.ContentLength > 0) 
    {
        var fileName = Path.GetFileName(file.FileName);
        var path = Path.Combine(Server.MapPath("~/content/pics"), fileName);
        file.SaveAs(path);
    }
    return RedirectToAction("Upload");
}

Of all of the answers here, I think they either don't work, or they're a bit of a hack (casting back to NSString). It's very likely that the correct answer to this has changed with the different beta releases.

Here is what I use:

let string: String = "hello Swift"
if string.rangeOfString("Swift") != nil
{
    println("exists")
}

The "!= nil" became required with Beta 5.

Here is what i did

 int color=//your color
 Integer.toHexString(color).toUpperCase();//upercase with alpha
 Integer.toHexString(color).toUpperCase().substring(2);// uppercase without alpha

Thanks guys you answers did the thing

Yes you have to if you take the unique_ptr by value in the constructor. Explicity is a nice thing. Since unique_ptr is uncopyable (private copy ctor), what you wrote should give you a compiler error.

simple * rawurlencode the path - path is the part before the "?" - spaces must be encoded as %20 * urlencode the query string - Query string is the part after the "?" -spaces are better encoded as "+" = rawurlencode is more compatible generally

As mentioned, display:inline is probably what you want. Some browsers also support inline-blocks.

http://www.quirksmode.org/css/display.html#inlineblock

If you read through any of the discussions on the android development group you will see that they discourage the use of anything that isn't in the public SDK because the rest is subject to extensive change.

The solution takes two steps!

First, complete the user, domain, and proxy fields in cntlm.ini. The username and domain should probably be whatever you use to log in to Windows at your office, eg.

Username            employee1730
Domain              corporate
Proxy               proxy.infosys.corp:8080

Then test cntlm with a command such as

cntlm.exe -c cntlm.ini -I -M http://www.bbc.co.uk

It will ask for your password (again whatever you use to log in to Windows_). Hopefully it will print 'http 200 ok' somewhere, and print your some cryptic tokens authentication information. Now add these to cntlm.ini, eg:

Auth            NTLM
PassNT          A2A7104B1CE00000000000000007E1E1
PassLM          C66000000000000000000000008060C8

Finally, set the http_proxy environment variable in Windows (assuming you didn't change with the Listen field which by default is set to 3128) to the following

http://localhost:3128

Pickle is a module installed for both Python 2 and Python 3 by default. See the standard library for 3.6.4 and 2.7.

Also to prove what I am saying is correct try running this script:

import pickle
print(pickle.__doc__)

This will print out the Pickle documentation showing you all the functions (and a bit more) it provides.

Or you can start the integrated Python 3.6 Module Docs and check there.

As a rule of thumb: if you can import the module without an error being produced then it is installed

The reason for the No matching distribution found for pickle is because libraries for included packages are not available via pip because you already have them (I found this out yesterday when I tried to install an integrated package).

If it's running without errors but it doesn't work as expected I would think that you made a mistake somewhere (perhaps quickly check the functions you are using in the docs). Python is very informative with it's errors so we generally know if something is wrong.

Let's say in Swift 4 you have a button set up for a segue as an IBAction like this @IBAction func nextLevel(_ sender: UIButton) {} and you have other actions occurring within your app (i.e. a timer, gamePlay, etc.). Rather than disabling the segue button, you might want to give your user the option to use that segue while the other actions are still occurring and WITHOUT CRASHING THE APP. Here's how:

var appMode = 0

@IBAction func mySegue(_ sender: UIButton) {

    if appMode == 1 {  // avoid crash if button pressed during other app actions and/or conditions
        let conflictingAction = sender as UIButton
        conflictingAction.isEnabled = false
    }
}

Please note that you will likely have other conditions within if appMode == 0 and/or if appMode == 1 that will still occur and NOT conflict with the mySegue button. Thus, AVOIDING A CRASH.

Here's what happened to me: the server was returning a malformed "Location" header for a 302 redirect. Chrome failed to tell me this, of course. I opened the page in firefox, and immediately discovered the problem. Nice to have multiple tools :)

header('Content-type: text/html; charset=utf-8');

input in your page.

I had the "file not found" problem, so I moved the "root" definition up into the "server" bracket to provide a default value for all the locations. You can always override this by giving any location it's own root.

server {
    root /usr/share/nginx/www;
    location / {
            #root /usr/share/nginx/www;
    }

    location ~ \.php$ {
            try_files $uri =404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass 127.0.0.1:9000;
            fastcgi_index index.php;
            include fastcgi_params;
    }
}

Alternatively, I could have defined root in both my locations.

My "DerivedData" with Xcode 10.2 and Mojave was here:

MacHD/Users/[MyUser]/Library/Developer/Xcode

the World Wide Web Consortium HTML Validator is great at catching HTML errors.

I've meet the probleme recently. The trouble is coming when the filename lenght is greather than 20 characters. So the bypass is to change your filename length, but the trick is also a good one.

$.ajaxSetup({async: false}); // passage en mode synchrone
$.ajax({
   url: pathpays,
   success: function(data) {
      //debug(data);
      $(data).find("a:contains(.png),a:contains(.jpg)").each(function() {
         var image = $(this).attr("href");
         // will loop through
         debug("Found a file: " + image);
         text +=  '<img class="arrondie" src="' + pathpays + image + '" />';
      });
      text = text + '</div>';
      //debug(text);
   }
});

After more investigation the trouble is coming from ajax request: Put an eye to the html code returned by ajax:

<a href="Paris-Palais-de-la-cite%20-%20Copie.jpg">Paris-Palais-de-la-c..&gt;</a>
</td>
<td align="right">2015-09-05 09:50 </td>
<td align="right">4.3K</td>
<td>&nbsp;</td>
</tr>

As you can see the filename is splitted after the character 20, so the $(data).find("a:contains(.png)) is not able to find the correct extention.

But if you check the value of the href parameter it contents the fullname of the file.

I dont know if I can to ask to ajax to return the full filename in the text area?

Hope to be clear

I've found the right test to gather all files:

$(data).find("[href$='.jpg'],[href$='.png']").each(function() {  
var image = $(this).attr("href");

Reading input from keyboard is analogous to downloading files from the internet, the java io system opens connections with the source of data to be read using InputStream or Reader, you have to handle a situation where the connection can break by using IOExceptions

If you want to know exactly what it means to work with InputStreams and BufferedReader this video shows it

Try removing all previous architectures (i.e. remove the ARCHS_STANDARD setting) at the same time as you add i386 to the Architectures. This should change the active architecture to i386. I encountered a similar issue when I tried to build for armv7 by default, but it kept trying to build for arm64. I changed ARCHS_STANDARD to ARCHS_STANDARD_32_BIT, and this changed the active architecture chosen.

I wrote a wrapper using the ExpressionTree variant and c#7 (if somebody is interested):

public class Accessor<T>
{
    private Action<T> Setter;
    private Func<T> Getter;

    public Accessor(Expression<Func<T>> expr)
    {
        var memberExpression = (MemberExpression)expr.Body;
        var instanceExpression = memberExpression.Expression;
        var parameter = Expression.Parameter(typeof(T));

        if (memberExpression.Member is PropertyInfo propertyInfo)
        {
            Setter = Expression.Lambda<Action<T>>(Expression.Call(instanceExpression, propertyInfo.GetSetMethod(), parameter), parameter).Compile();
            Getter = Expression.Lambda<Func<T>>(Expression.Call(instanceExpression, propertyInfo.GetGetMethod())).Compile();
        }
        else if (memberExpression.Member is FieldInfo fieldInfo)
        {
            Setter = Expression.Lambda<Action<T>>(Expression.Assign(memberExpression, parameter), parameter).Compile();
            Getter = Expression.Lambda<Func<T>>(Expression.Field(instanceExpression,fieldInfo)).Compile();
        }

    }

    public void Set(T value) => Setter(value);

    public T Get() => Getter();
}

And use it like:

var accessor = new Accessor<string>(() => myClient.WorkPhone);
accessor.Set("12345");
Assert.Equal(accessor.Get(), "12345");

Yes. Only override it in that one Activity with

@Override
public void onBackPressed()
{
     // code here to show dialog
     super.onBackPressed();  // optional depending on your needs
}

don't put this code in any other Activity

ytd2 is a fully functional YouTube video downloader. Check out its source code if you want to see how it's done.

Alternatively, you can also call an external process like youtube-dl to do the job. This is probably the easiest solution but it isn't in "pure" Java.

Yes, you are using it incorrectly, Series.replace() is not inplace operation by default, it returns the replaced dataframe/series, you need to assign it back to your dataFrame/Series for its effect to occur. Or if you need to do it inplace, you need to specify the inplace keyword argument as True Example -

data['sex'].replace(0, 'Female',inplace=True)
data['sex'].replace(1, 'Male',inplace=True)

Also, you can combine the above into a single replace function call by using list for both to_replace argument as well as value argument , Example -

data['sex'].replace([0,1],['Female','Male'],inplace=True)

Example/Demo -

In [10]: data = pd.DataFrame([[1,0],[0,1],[1,0],[0,1]], columns=["sex", "split"])

In [11]: data['sex'].replace([0,1],['Female','Male'],inplace=True)

In [12]: data
Out[12]:
      sex  split
0    Male      0
1  Female      1
2    Male      0
3  Female      1

You can also use a dictionary, Example -

In [15]: data = pd.DataFrame([[1,0],[0,1],[1,0],[0,1]], columns=["sex", "split"])

In [16]: data['sex'].replace({0:'Female',1:'Male'},inplace=True)

In [17]: data
Out[17]:
      sex  split
0    Male      0
1  Female      1
2    Male      0
3  Female      1

Try this one:

var lastfoucsin;

$('.txtclassname').click(function(e)
{
  lastfoucsin=$(this);

//the virtual keyboard appears automatically

//Do your stuff;

});


//to check ipad virtual keyboard appearance. 
//First check last focus class and close the virtual keyboard.In second click it closes the wrapper & lable

$(".wrapperclass").click(function(e)
{

if(lastfoucsin.hasClass('txtclassname'))
{

lastfoucsin=$(this);//to avoid error

return;

}

//Do your stuff 
$(this).css('display','none');
});`enter code here`

Your object can also implement the Parcelable interface. Then you can use the Bundle.putParcelable() method and pass your object between activities within intent.

The Photostream application uses this approach and may be used as a reference.

[id] [int] IDENTITY(1,1) NOT NULL,

of course since you're creating the table in SQL Server Management Studio you could use the table designer to set the Identity Specification.

To add to the answers already given, having the img-responsive in combination with img-thumbnail will set display: block to display: inline block.

Can Google Chrome open local links?

In my case I had to open the file:

C:\...\Documents\IISExpress\config\applicationhost.config

I had this inside the file:

  <authentication>
  <anonymousAuthentication enabled="true" User="" />

I just removed the User="" part. I really don't know how this thing got there... :)

Note: Make sure you have something like this in the end of applicationhost.config:

   .
   .
   .
   <location path="MyCompany.MyProjectName.Web">
        <system.webServer>
            <security>
                <authentication>
                    <anonymousAuthentication enabled="true" />
                    <windowsAuthentication enabled="false" />
                </authentication>

</configuration>

Now I can access the login page as expected.

It's fine, the continue statement relates to the enclosing loop, and your code should be equivalent to (avoiding such jump statements):

while (something = get_something()) {
    if (something == A || something == B)
        do_something();
}

But if you expect break to exit the loop, as your comment suggest (it always tries again with another something, until it evaluates to false), you'll need a different structure.

For example:

do {
    something = get_something();
} while (!(something == A || something == B));
do_something();

MySQLdb will not raise an exception if the result set is empty. Additionally cursor.execute() function will return a long value which is number of rows in the fetched result set. So if you want to check for empty results, your code can be re-written as

rows_count = cursor.execute(query_sql)
if rows_count > 0:
     rs = cursor.fetchall()
else:
     // handle empty result set

i tried putting distinct on both, count(distinct ord.ord_id) as num_order, count(distinct items.item_id) as num items

its working :)

    SELECT
         people.pe_name,
         COUNT(distinct orders.ord_id) AS num_orders,
         COUNT(distinct items.item_id) AS num_items
    FROM
         people
         INNER JOIN orders ON (orders.pe_id = people.pe_id)
         INNER JOIN items ON items.pe_id = people.pe_id
    GROUP BY
         people.pe_id;

Thanks for the Thread it helps :)

I will prefer moment js

startDate = moment().subtract(30, 'days').format('LL')  // January 29, 2015

endDate = moment().format('LL'); // February 28, 2015

You better setup a single test and create a performance test from this test. This way you can monitor the progress using the default tool set.

For me only this one worked

git checkout -p filename

You have at least two issues in your code:

• ng-change="getScoreData(Score)

  Angular doesn't see getScoreData method that refers to defined service

• getScoreData: function (Score, callback)

  We don't need to use callback since GET returns promise. Use then instead.

Here is a working example (I used random address only for simulation):

HTML

<select ng-model="score"
        ng-change="getScoreData(score)" 
        ng-options="score as score.name for score in  scores"></select>
    <pre>{{ScoreData|json}}</pre> 

JS

var fessmodule = angular.module('myModule', ['ngResource']);

fessmodule.controller('fessCntrl', function($scope, ScoreDataService) {

    $scope.scores = [{
        name: 'Bukit Batok Street 1',
        URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, 153 Bukit Batok Street 1&sensor=true'
    }, {
        name: 'London 8',
        URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, London 8&sensor=true'
    }];

    $scope.getScoreData = function(score) {
        ScoreDataService.getScoreData(score).then(function(result) {
            $scope.ScoreData = result;
        }, function(result) {
            alert("Error: No data returned");
        });
    };

});

fessmodule.$inject = ['$scope', 'ScoreDataService'];

fessmodule.factory('ScoreDataService', ['$http', '$q', function($http) {

    var factory = {
        getScoreData: function(score) {
            console.log(score);
            var data = $http({
                method: 'GET',
                url: score.URL
            });


            return data;
        }
    }
    return factory;
}]);

If you are using version ranges for any dependencies, make sure that IntelliJ is using Maven 3 to import the project. You can find this setting in: Settings > Maven > Importing > Use Maven3 to import project. Otherwise you may find that SNAPSHOT versions are not imported correctly.

By this you can get any index in *ngFor loop in ANGULAR ...

<ul>
  <li *ngFor="let object of myArray; let i = index; let first = first ;let last = last;">
    <div *ngIf="first">
       // write your code...
    </div>

    <div *ngIf="last">
       // write your code...
    </div>
  </li>
</ul>

We can use these alias in *ngFor

• index : number : let i = index to get all index of object.
• first : boolean : let first = first to get first index of object.
• last : boolean : let last = last to get last index of object.
• odd : boolean : let odd = odd to get odd index of object.
• even : boolean : let even = even to get even index of object.

Try to change like this ..

firstStr = "<?xml version" 'my file always starts like this

Do until objInputFile.AtEndOfStream  

    strToAdd = "<tr><td><a href=" & chr(34) & "../../Logs/DD/Beginning_of_DD_TC" & CStr(index) & ".html" & chr(34) & ">Beginning_of_DD_TC" & CStr(index) & "</a></td></tr>"  

   substrToFind = "<tr><td><a href=" & chr(34) & "../Test case " & trim(cstr((index)))

   tmpStr = objInputFile.ReadLine

   If InStr(tmpStr, substrToFind) <= 0 Then
       If Instr(tmpStr, firstStr) > 0 Then
          text = tmpStr 'to avoid the first empty line
       Else
          text = text & vbCrLf & tmpStr
       End If
   Else
      text = text & vbCrLf & strToAdd & vbCrLf & tmpStr

   End If
   index = index + 1
Loop

SELECT * FROM ... WHERE name = 'someone' COLLATE NOCASE

if your column is varchar use annotation length

@Column(length = 255)

or use another column type

@Column(columnDefinition="TEXT")

I can assure you that raw speed ultimately lies in the non-standard use of Indexes for blazing speed using large tables.

In Python 3:

def is_prime(a):
    if a < 2:
        return False
    elif a!=2 and a % 2 == 0:
        return False
    else:
        return all (a % i for i in range(3, int(a**0.5)+1))

Explanation: A prime number is a number only divisible by itself and 1. Ex: 2,3,5,7...

1) if a<2: if "a" is less than 2 it is not a prime.

2) elif a!=2 and a % 2 == 0: if "a" is divisible by 2 then its definitely not a prime. But if a=2 we don't want to evaluate that as it is a prime number. Hence the condition a!=2

3) return all (a % i for i in range(3, int(a0.5)+1) ):** First look at what all() command does in python. Starting from 3 we divide "a" till its square root (a**0.5). If "a" is divisible the output will be False. Why square root? Let's say a=16. The square root of 16 = 4. We don't need to evaluate till 15. We only need to check till 4 to say that it's not a prime.

Extra: A loop for finding all the prime number within a range.

for i in range(1,100):
    if is_prime(i):
        print("{} is a prime number".format(i))

The whole code if somebody need it.

void alarm(Context context, Calendar calendar) {
    AlarmManager alarmManager = (AlarmManager)context.getSystemService(ALARM_SERVICE);

    final String SOME_ACTION = "com.android.mytabs.MytabsActivity.AlarmReceiver";
    IntentFilter intentFilter = new IntentFilter(SOME_ACTION);

    AlarmReceiver mReceiver = new AlarmReceiver();
    context.registerReceiver(mReceiver, intentFilter);

    Intent anotherIntent = new Intent(SOME_ACTION);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, anotherIntent, 0);
    alramManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pendingIntent);

    Toast.makeText(context, "Added", Toast.LENGTH_LONG).show();
}

class AlarmReceiver extends BroadcastReceiver {     
    @Override
    public void onReceive(Context context, Intent arg1) {
        Toast.makeText(context, "Started", Toast.LENGTH_LONG).show();
    }
}

I tried so many different things and finally found what worked best for me was simply adding in padding-right: 28px;

I played around with the padding to get the right amount to evenly space the items.

A POCO follows the rules of OOP. It should (but doesn't have to) have state and behavior. POCO comes from POJO, coined by Martin Fowler [anecdote here]. He used the term POJO as a way to make it more sexy to reject the framework heavy EJB implementations. POCO should be used in the same context in .Net. Don't let frameworks dictate your object's design.

A DTO's only purpose is to transfer state, and should have no behavior. See Martin Fowler's explanation of a DTO for an example of the use of this pattern.

Here's the difference: POCO describes an approach to programming (good old fashioned object oriented programming), where DTO is a pattern that is used to "transfer data" using objects.

While you can treat POCOs like DTOs, you run the risk of creating an anemic domain model if you do so. Additionally, there's a mismatch in structure, since DTOs should be designed to transfer data, not to represent the true structure of the business domain. The result of this is that DTOs tend to be more flat than your actual domain.

In a domain of any reasonable complexity, you're almost always better off creating separate domain POCOs and translating them to DTOs. DDD (domain driven design) defines the anti-corruption layer (another link here, but best thing to do is buy the book), which is a good structure that makes the segregation clear.

<context:annotation-config>: Scanning and activating annotations for already registered beans in spring config xml.

<context:component-scan>: Bean registration + <context:annotation-config>

@Autowired and @Required are targets property level so bean should register in spring IOC before use these annotations. To enable these annotations either have to register respective beans or include <context:annotation-config />. i.e. <context:annotation-config /> works with registered beans only.

@Required enables RequiredAnnotationBeanPostProcessor processing tool
@Autowired enables AutowiredAnnotationBeanPostProcessor processing tool

Note: Annotation itself nothing to do, we need a Processing Tool, which is a class underneath, responsible for the core process.

@Repository, @Service and @Controller are @Component, and they targets class level.

<context:component-scan> it scans the package and find and register the beans, and it includes the work done by <context:annotation-config />.

Migrating XML to Annotations

setup.py is designed to be run from the command line. You'll need to open your command prompt (In Windows 7, hold down shift while right-clicking in the directory with the setup.py file. You should be able to select "Open Command Window Here").

From the command line, you can type

python setup.py --help

...to get a list of commands. What you are looking to do is...

python setup.py install

Further to @RobG's pure / vanilla javascript answer, you can reset to the 'default' value with

selectElement.selectedIndex = null;

It seems -1 deselects all items, null selects the default item, and 0 or a positive number selects the corresponding index option.

Options in a select object are indexed in the order in which they are defined, starting with an index of 0.

source

if (select == "") {
    alert("Please select a selection");
    return false;

That should work for you. It just did for me.

Since I can not comment because of not having enough reward points I have to answer to correct answer given by @Burhan Khalid.
In very layman language Enter key press is combination of carriage return and line feed.
Carriage return points the cursor to the beginning of the line horizontly and Line feed shifts the cursor to the next line vertically.Combination of both gives you new line(\n) effect.

I also had the same problem while accessing RESTful web services. And I their with the below code to overcome the issue:

public class Test {
    //Bypassing the SSL verification to execute our code successfully 
    static {
        disableSSLVerification();
    }

    public static void main(String[] args) {    
        //Access HTTPS URL and do something    
    }
    //Method used for bypassing SSL verification
    public static void disableSSLVerification() {

        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 = null;
        try {
            sc = SSLContext.getInstance("SSL");
            sc.init(null, trustAllCerts, new java.security.SecureRandom());
        } catch (KeyManagementException e) {
            e.printStackTrace();
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        }
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());

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

It worked for me. try it!!

I had a similar situation, and after fruitless Googles, I declared a public string, which mods a string value of the debug / release path to get the project path. A benefit of using this method is that since it uses the currect project's directory, it matters not if you are working from a debug directory or a release directory:

public string DirProject()
{
    string DirDebug = System.IO.Directory.GetCurrentDirectory();
    string DirProject = DirDebug;

    for (int counter_slash = 0; counter_slash < 4; counter_slash++)
    {
        DirProject = DirProject.Substring(0, DirProject.LastIndexOf(@"\"));
    }

    return DirProject;
}

You would then be able to call it whenever you want, using only one line:

string MyProjectDir = DirProject();

This should work in most cases.

In case you don't have permission to 'Modify', you can install a free tool called "SQL Search" (by Redgate). I use it to search for keywords that I know will be in the SP and it returns a preview of the SP code with the keywords highlighted.

Ingenious! I then copy this code into my own SP.

If we combine what @Hendy and @Oddysseus Ithaca contributed, we get cleaner and a more general (i.e., adaptable?) chunk of code.

    data <- read.csv("test.csv", head = F, colClasses = c(V36 = "character", V38 = "character"))                        

Specify the version you want in the 'dependencies' section of your package.json, then from your root project folder in the console/terminal run this:

npm install

For example, the following will specifically install v4.3.4

"dependencies": {
    "@angular/common": "4.3.4",
    "@angular/compiler": "4.3.4",
    "@angular/core": "4.3.4",
    "@angular/forms": "4.3.4",
    "@angular/http": "4.3.4",
    "@angular/platform-browser": "4.3.4",
    "@angular/platform-browser-dynamic": "4.3.4",
    "@angular/router": "4.3.4",
  }

You can also add the following modifiers to the version number to vary how specific you need the version to be:

caret ^

Updates you to the most recent major version, as specified by the first number:

^4.3.0

will load the latest 4.x.x release, but will not load 5.x.x

tilde ~

Update you to the most recent minor version, as specified by the second number:

~4.3.0

will load the latest 4.3.x release, but will not load 4.4.x

CSV files have no limit of rows you can add to them. Excel won't hold more that the 1 million lines of data if you import a CSV file having more lines.

Excel will actually ask you whether you want to proceed when importing more than 1 million data rows. It suggests to import the remaining data by using the text import wizard again - you will need to set the appropriate line offset.

To answer your direct question, it is:

Range("A1").NumberFormat = "@"

Or

Cells(1,1).NumberFormat = "@"

However, I suggest making changing the format to what you actually want displayed. This allows you to retain the data type in the cell and easily use cell formulas to manipulate the data.

Ok, I don't normally answer my own questions but after a bit of tinkering, I have figured out definitively how Oracle stores the result of a DATE subtraction.

When you subtract 2 dates, the value is not a NUMBER datatype (as the Oracle 11.2 SQL Reference manual would have you believe). The internal datatype number of a DATE subtraction is 14, which is a non-documented internal datatype (NUMBER is internal datatype number 2). However, it is actually stored as 2 separate two's complement signed numbers, with the first 4 bytes used to represent the number of days and the last 4 bytes used to represent the number of seconds.

An example of a DATE subtraction resulting in a positive integer difference:

select date '2009-08-07' - date '2008-08-08' from dual;

Results in:

DATE'2009-08-07'-DATE'2008-08-08'
---------------------------------
                              364

select dump(date '2009-08-07' - date '2008-08-08') from dual;

DUMP(DATE'2009-08-07'-DATE'2008
-------------------------------
Typ=14 Len=8: 108,1,0,0,0,0,0,0

Recall that the result is represented as a 2 seperate two's complement signed 4 byte numbers. Since there are no decimals in this case (364 days and 0 hours exactly), the last 4 bytes are all 0s and can be ignored. For the first 4 bytes, because my CPU has a little-endian architecture, the bytes are reversed and should be read as 1,108 or 0x16c, which is decimal 364.

An example of a DATE subtraction resulting in a negative integer difference:

select date '1000-08-07' - date '2008-08-08' from dual;

Results in:

DATE'1000-08-07'-DATE'2008-08-08'
---------------------------------
                          -368160

select dump(date '1000-08-07' - date '2008-08-08') from dual;

DUMP(DATE'1000-08-07'-DATE'2008-08-0
------------------------------------
Typ=14 Len=8: 224,97,250,255,0,0,0,0

Again, since I am using a little-endian machine, the bytes are reversed and should be read as 255,250,97,224 which corresponds to 11111111 11111010 01100001 11011111. Now since this is in two's complement signed binary numeral encoding, we know that the number is negative because the leftmost binary digit is a 1. To convert this into a decimal number we would have to reverse the 2's complement (subtract 1 then do the one's complement) resulting in: 00000000 00000101 10011110 00100000 which equals -368160 as suspected.

An example of a DATE subtraction resulting in a decimal difference:

select to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS'
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS') from dual;

TO_DATE('08/AUG/200414:00:00','DD/MON/YYYYHH24:MI:SS')-TO_DATE('08/AUG/20048:00:
--------------------------------------------------------------------------------
                                                                             .25

The difference between those 2 dates is 0.25 days or 6 hours.

select dump(to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS')
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS')) from dual;

DUMP(TO_DATE('08/AUG/200414:00:
-------------------------------
Typ=14 Len=8: 0,0,0,0,96,84,0,0

Now this time, since the difference is 0 days and 6 hours, it is expected that the first 4 bytes are 0. For the last 4 bytes, we can reverse them (because CPU is little-endian) and get 84,96 = 01010100 01100000 base 2 = 21600 in decimal. Converting 21600 seconds to hours gives you 6 hours which is the difference which we expected.

Hope this helps anyone who was wondering how a DATE subtraction is actually stored.

You get the syntax error because the date math does not return a NUMBER, but it returns an INTERVAL:

SQL> SELECT DUMP(SYSDATE - start_date) from test;

DUMP(SYSDATE-START_DATE)
-------------------------------------- 
Typ=14 Len=8: 188,10,0,0,223,65,1,0

You need to convert the number in your example into an INTERVAL first using the NUMTODSINTERVAL Function

For example:

SQL> SELECT (SYSDATE - start_date) DAY(5) TO SECOND from test;

(SYSDATE-START_DATE)DAY(5)TOSECOND
----------------------------------
+02748 22:50:04.000000

SQL> SELECT (SYSDATE - start_date) from test;

(SYSDATE-START_DATE)

Based on the reverse cast with the NUMTODSINTERVAL() function, it appears some rounding is lost in translation.

You can store your find output in array if you wish to use the output later as:

array=($(find . -name "*.txt"))

Now to print the each element in new line, you can either use for loop iterating to all the elements of array, or you can use printf statement.

for i in ${array[@]};do echo $i; done

or

printf '%s\n' "${array[@]}"

You can also use:

for file in "`find . -name "*.txt"`"; do echo "$file"; done

This will print each filename in newline

To only print the find output in list form, you can use either of the following:

find . -name "*.txt" -print 2>/dev/null

or

find . -name "*.txt" -print | grep -v 'Permission denied'

This will remove error messages and only give the filename as output in new line.

If you wish to do something with the filenames, storing it in array is good, else there is no need to consume that space and you can directly print the output from find.

As detailed out in the bookdown documentation, you could also use a paged table

mtcars %>% tbl_df %>% rmarkdown::paged_table()

This will paginate the data and allows to browse all rows and columns (unless configured to cap the rows). Example:

The pathlib library is really great for working with files. You can do a recursive glob on a Path object like so.

from pathlib import Path

for elem in Path('/path/to/my/files').rglob('*.*'):
    print(elem)

I had this same problem. As Dedren says, the problem is not the query, but the form object's control source. Put [] around each objects Control Source. eg: Contol Source: [Product number], Control Source: Salesperson.[Salesperson number], etc.

Makita recomends going to the original table that you are referencing in your query and rename the field so that there are no spaces eg: SalesPersonNumber, ProductNumber, etc. This will solve many future problems as well. Best of Luck!

You gave a condition ID (>79 and < 296) then the answer is:

delete from tab
where id > 79 and id < 296

this is the same as:

delete from tab
where id between 80 and 295

if id is an integer.

All answered:

delete from tab
where id between 79 and 296

this is the same as:

delete from tab
where id => 79 and id <= 296

Mind the difference.

In your view:

{% if user.is_authenticated %}
<p>{{ user }}</p>
{% endif %}

In you controller functions add decorator:

from django.contrib.auth.decorators import login_required
@login_required
def privateFunction(request):

They are both correct. Personally I prefer your approach better for its verbosity but it's really down to personal preference.

Off hand, running if($_POST) would not throw an error - the $_POST array exists regardless if the request was sent with POST headers. An empty array is cast to false in a boolean check.

Unset will destroy a particular session variable whereas session_destroy() will destroy all the session data for that user.

It really depends on your application as to which one you should use. Just keep the above in mind.

unset($_SESSION['name']); // will delete just the name data

session_destroy(); // will delete ALL data associated with that user.

The above answeres have the following problems:

1. They update everything including your app (in case you have uncommitted changes).
2. They updated packages you may have already removed from your project but are already on your disk.

To avoid these, do the following:

1. Delete the 3rd party folders that you want to update.
2. go to your app folder and run go get -d

Vertical align doesn't quite work the way you want it to. See: http://phrogz.net/css/vertical-align/index.html

This isn't pretty, but it WILL do what you want: Vertical align behaves as expected only when used in a table cell.

http://jsfiddle.net/e8ESb/6/

There are other alternatives: You can declare things as tables or table cells within CSS to make them behave as desired, for example. Margins and positioning can sometimes be played with to get the same effect. None of the solutions are terrible pretty, though.

The option provided by"praveenak" can also be applied to any other jar files with source file provided. For example, for JavaFx, we right click jfxrt.jar, select "Properties" and enter jdk1.8.0_05/javafx-src.zip for "Path" under External location.

Method 1

One simple way to confirm is to use the native browser confirm alert. The template can have a button or link.

<button type=button class="btn btn-primary"  (click)="clickMethod('name')">Delete me</button>

And the component method can be something like below.

clickMethod(name: string) {
  if(confirm("Are you sure to delete "+name)) {
    console.log("Implement delete functionality here");
  }
}

Method 2

Another way to get a simple confirmation dialog is to use the angular bootstrap components like ng-bootstrap or ngx-bootstrap. You can simply install the component and use the modal component.

1. Examples of modals using ng-bootstrap
2. Examples of modals using ngx-bootstrap.

Method 3

Provided below is another way to implement a simple confirmation popup using angular2/material that I implemented in my project.

app.module.ts

import { FormsModule, ReactiveFormsModule } from '@angular/forms';
import { ConfirmationDialog } from './confirm-dialog/confirmation-dialog';

@NgModule({
  imports: [
    ...
    FormsModule,
    ReactiveFormsModule
  ],
  declarations: [
    ...
    ConfirmationDialog
  ],
  providers: [ ... ],
  bootstrap: [ AppComponent ],
  entryComponents: [ConfirmationDialog]
})
export class AppModule { }

confirmation-dialog.ts

import { Component, Input } from '@angular/core';
import { MdDialog, MdDialogRef } from '@angular/material';

@Component({
  selector: 'confirm-dialog',
  templateUrl: '/app/confirm-dialog/confirmation-dialog.html',
})
export class ConfirmationDialog {
  constructor(public dialogRef: MdDialogRef<ConfirmationDialog>) {}

  public confirmMessage:string;
}

confirmation-dialog.html

<h1 md-dialog-title>Confirm</h1>
<div md-dialog-content>{{confirmMessage}}</div>
<div md-dialog-actions>
  <button md-button style="color: #fff;background-color: #153961;" (click)="dialogRef.close(true)">Confirm</button>
  <button md-button (click)="dialogRef.close(false)">Cancel</button>
</div>

app.component.html

<button (click)="openConfirmationDialog()">Delete me</button>

app.component.ts

import { MdDialog, MdDialogRef } from '@angular/material';
import { ConfirmationDialog } from './confirm-dialog/confirmation-dialog';

@Component({
  moduleId: module.id,
  templateUrl: '/app/app.component.html',
  styleUrls: ['/app/main.css']
})

export class AppComponent implements AfterViewInit {
  dialogRef: MdDialogRef<ConfirmationDialog>;

  constructor(public dialog: MdDialog) {}

  openConfirmationDialog() {
    this.dialogRef = this.dialog.open(ConfirmationDialog, {
      disableClose: false
    });
    this.dialogRef.componentInstance.confirmMessage = "Are you sure you want to delete?"

    this.dialogRef.afterClosed().subscribe(result => {
      if(result) {
        // do confirmation actions
      }
      this.dialogRef = null;
    });
  }
}

index.html => added following stylesheet

<link rel="stylesheet" href="node_modules/@angular/material/core/theming/prebuilt/indigo-pink.css">

Try using these theme: Theme.AppCompat.Light.NoActionBar

Mi Style XML file looks like these and works just fine:

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

You have your storyboard set up to expect an outlet called tableView but the actual outlet name is myTableView.

If you delete the connection in the storyboard and reconnect to the right variable name, it should fix the problem.

I've got a better work around than OCR and to maintain the page alignment while extracting the text from a PDF. Should be of help:

from pdfminer.pdfinterp import PDFResourceManager, PDFPageInterpreter
from pdfminer.converter import TextConverter
from pdfminer.layout import LAParams
from pdfminer.pdfpage import PDFPage
from io import StringIO

def convert_pdf_to_txt(path):
    rsrcmgr = PDFResourceManager()
    retstr = StringIO()
    codec = 'utf-8'
    laparams = LAParams()
    device = TextConverter(rsrcmgr, retstr, codec=codec, laparams=laparams)
    fp = open(path, 'rb')
    interpreter = PDFPageInterpreter(rsrcmgr, device)
    password = ""
    maxpages = 0
    caching = True
    pagenos=set()


    for page in PDFPage.get_pages(fp, pagenos, maxpages=maxpages, password=password,caching=caching, check_extractable=True):
        interpreter.process_page(page)


    text = retstr.getvalue()

    fp.close()
    device.close()
    retstr.close()
    return text

text= convert_pdf_to_txt('test.pdf')
print(text)

I made a quick project in visual studio 2008 for a .net 3.5 C# windows form application and was able to create the following code. I found events for both the enter and leave methods.

In the InitializeComponent() function. I added the event handler using the Visual Studio designer.

this.button1.MouseLeave += new System.EventHandler( this.button1_MouseLeave );
this.button1.MouseEnter += new System.EventHandler( this.button1_MouseEnter );

In the button event handler methods set the background images.

/// <summary>
/// Handles the MouseEnter event of the button1 control.
/// </summary>
/// <param name="sender">The source of the event.</param>
/// <param name="e">The <see cref="System.EventArgs"/> instance containing the event data.</param>
private void button1_MouseEnter( object sender, EventArgs e )
{
      this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img2));
}

/// <summary>
/// Handles the MouseLeave event of the button1 control.
/// </summary>
/// <param name="sender">The source of the event.</param>
/// <param name="e">The <see cref="System.EventArgs"/> instance containing the event data.</param>
private void button1_MouseLeave( object sender, EventArgs e )
{
       this.button1.BackgroundImage = ((System.Drawing.Image)(Properties.Resources.img1));
}

var checkboxes = document.getElementsByName('location[]');
var vals = "";
for (var i=0, n=checkboxes.length;i<n;i++) 
{
    if (checkboxes[i].checked) 
    {
        vals += ","+checkboxes[i].value;
    }
}
if (vals) vals = vals.substring(1);

You may want to use WildcardPattern from System.Management.Automation assembly. See my answer here.

First, you should understand the pointer is not complex. A pointer is showing the address of the variable.

Example:

int a = 10;
int *p = &a;  // This means giving a pointer of variable "a" to int pointer variable "p"

And, you should understand "Pointer is an address" and "address is numerical value". So, you can get the address of variable as Integer.

int a = 10;
unsigned long address = (unsigned long)&a;

// comparison
printf("%p\n", &a);
printf("%ld\n", address);

output is below

0x7fff1216619c
7fff1216619c

Note:

If you use a 64-bit computer, you can't get pointer by the way below.

int a = 10;
unsigned int address = (unsigned int)&a;

Because pointer is 8 bytes (64 bit) on a 64-bit machine, but int is 4 bytes. So, you can't give an 8-byte memory address to 4 bytes variable.

You have to use long long or long to get an address of the variable.

• long long is always 8 bytes.
• long is 4 bytes when code was compiled for a 32-bit machine.
• long is 8 bytes when code was compiled for a 64-bit machine.

Therefore, you should use long to receive a pointer.

I found the I could get around this problem by changing the target location from obj/[release|stage|..] to a new path outside of the solution folders completely eg c:\deployment. It seems like VS 2012 was getting confused and maybe giving up somewhere during the publish process.

Use the -p flag and add /udp suffix to the port number.

-p 53160:53160/udp

Full command

sudo docker run -p 53160:53160 \
    -p 53160:53160/udp -p 58846:58846 \ 
    -p 8112:8112 -t -i aostanin/deluge /start.sh

If you're running boot2docker on Mac, be sure to forward the same ports on boot2docker to your local machine.

You can also document that your container needs to receive UDP using EXPOSE in The Dockerfile (EXPOSE does not publish the port):

EXPOSE 8285/udp

Here is a link with more Docker Networking info covered in the container docs: https://docs.docker.com/config/containers/container-networking/ (Courtesy of Old Pro in the comments)

Deleting Elements in an Array if Element is a Certain value VBA

to delete elements in an Array wih certain condition, you can code like this

For i = LBound(ArrValue, 2) To UBound(ArrValue, 2)
    If [Certain condition] Then
        ArrValue(1, i) = "-----------------------"
    End If
Next i

StrTransfer = Replace(Replace(Replace(join(Application.Index(ArrValue(), 1, 0), ","), ",-----------------------,", ",", , , vbBinaryCompare), "-----------------------,", "", , , vbBinaryCompare), ",-----------------------", "", , , vbBinaryCompare)
ResultArray = join( Strtransfer, ",")

I often manipulate 1D-Array with Join/Split but if you have to delete certain value in Multi Dimension I suggest you to change those Array into 1D-Array like this

strTransfer = Replace(Replace(Replace(Replace(Names.Add("A", MultiDimensionArray), Chr(34), ""), "={", ""), "}", ""), ";", ",")
'somecode to edit Array like 1st code on top of this comment
'then loop through this strTransfer to get right value in right dimension
'with split function.

Remember that technically javascript objects don't have methods. They have properties, some of which may be function objects. That means that you can enumerate the methods in an object just like you can enumerate the properties. This (or something close to this) should work:

var bar
for (bar in foo)
{
    console.log("Foo has property " + bar);
}

There are complications to this because some properties of objects aren't enumerable so you won't be able to find every function on the object.

It is possible to do this by overwriting the Environment Table within a specified process itself.

As a proof of concept I wrote this sample app, which just edited a single (known) environment variable in a cmd.exe process:

typedef DWORD (__stdcall *NtQueryInformationProcessPtr)(HANDLE, DWORD, PVOID, ULONG, PULONG);

int __cdecl main(int argc, char* argv[])
{
    HMODULE hNtDll = GetModuleHandleA("ntdll.dll");
    NtQueryInformationProcessPtr NtQueryInformationProcess = (NtQueryInformationProcessPtr)GetProcAddress(hNtDll, "NtQueryInformationProcess");

    int processId = atoi(argv[1]);
    printf("Target PID: %u\n", processId);

    // open the process with read+write access
    HANDLE hProcess = OpenProcess(PROCESS_QUERY_LIMITED_INFORMATION | PROCESS_VM_READ | PROCESS_VM_WRITE | PROCESS_VM_OPERATION, 0, processId);
    if(hProcess == NULL)
    {
        printf("Error opening process (%u)\n", GetLastError());
        return 0;
    }

    // find the location of the PEB
    PROCESS_BASIC_INFORMATION pbi = {0};
    NTSTATUS status = NtQueryInformationProcess(hProcess, ProcessBasicInformation, &pbi, sizeof(pbi), NULL);
    if(status != 0)
    {
        printf("Error ProcessBasicInformation (0x%8X)\n", status);
    }
    printf("PEB: %p\n", pbi.PebBaseAddress);

    // find the process parameters
    char *processParamsOffset = (char*)pbi.PebBaseAddress + 0x20; // hard coded offset for x64 apps
    char *processParameters = NULL;
    if(ReadProcessMemory(hProcess, processParamsOffset, &processParameters, sizeof(processParameters), NULL))
    {
        printf("UserProcessParameters: %p\n", processParameters);
    }
    else
    {
        printf("Error ReadProcessMemory (%u)\n", GetLastError());
    }

    // find the address to the environment table
    char *environmentOffset = processParameters + 0x80; // hard coded offset for x64 apps
    char *environment = NULL;
    ReadProcessMemory(hProcess, environmentOffset, &environment, sizeof(environment), NULL);
    printf("environment: %p\n", environment);

    // copy the environment table into our own memory for scanning
    wchar_t *localEnvBlock = new wchar_t[64*1024];
    ReadProcessMemory(hProcess, environment, localEnvBlock, sizeof(wchar_t)*64*1024, NULL);

    // find the variable to edit
    wchar_t *found = NULL;
    wchar_t *varOffset = localEnvBlock;
    while(varOffset < localEnvBlock + 64*1024)
    {
        if(varOffset[0] == '\0')
        {
            // we reached the end
            break;
        }
        if(wcsncmp(varOffset, L"ENVTEST=", 8) == 0)
        {
            found = varOffset;
            break;
        }
        varOffset += wcslen(varOffset)+1;
    }

    // check to see if we found one
    if(found)
    {
        size_t offset = (found - localEnvBlock) * sizeof(wchar_t);
        printf("Offset: %Iu\n", offset);

        // write a new version (if the size of the value changes then we have to rewrite the entire block)
        if(!WriteProcessMemory(hProcess, environment + offset, L"ENVTEST=def", 12*sizeof(wchar_t), NULL))
        {
            printf("Error WriteProcessMemory (%u)\n", GetLastError());
        }
    }

    // cleanup
    delete[] localEnvBlock;
    CloseHandle(hProcess);

    return 0;
}

Sample output:

>set ENVTEST=abc

>cppTest.exe 13796
Target PID: 13796
PEB: 000007FFFFFD3000
UserProcessParameters: 00000000004B2F30
environment: 000000000052E700
Offset: 1528

>set ENVTEST
ENVTEST=def

Notes

This approach would also be limited to security restrictions. If the target is run at higher elevation or a higher account (such as SYSTEM) then we wouldn't have permission to edit its memory.

If you wanted to do this to a 32-bit app, the hard coded offsets above would change to 0x10 and 0x48 respectively. These offsets can be found by dumping out the _PEB and _RTL_USER_PROCESS_PARAMETERS structs in a debugger (e.g. in WinDbg dt _PEB and dt _RTL_USER_PROCESS_PARAMETERS)

To change the proof-of-concept into a what the OP needs, it would just enumerate the current system and user environment variables (such as documented by @tsadok's answer) and write the entire environment table into the target process' memory.

Edit: The size of the environment block is also stored in the _RTL_USER_PROCESS_PARAMETERS struct, but the memory is allocated on the process' heap. So from an external process we wouldn't have the ability to resize it and make it larger. I played around with using VirtualAllocEx to allocate additional memory in the target process for the environment storage, and was able to set and read an entirely new table. Unfortunately any attempt to modify the environment from normal means will crash and burn as the address no longer points to the heap (it will crash in RtlSizeHeap).

java.exe is the console app while javaw.exe is windows app (console-less). You can't have Console with javaw.exe.

In your case, breaking the hash algorithm is equivalent to finding a collision in the hash algorithm. That means you don't need to find the password itself (which would be a preimage attack), you just need to find an output of the hash function that is equal to the hash of a valid password (thus "collision"). Finding a collision using a birthday attack takes O(2^(n/2)) time, where n is the output length of the hash function in bits.

SHA-2 has an output size of 512 bits, so finding a collision would take O(2^256) time. Given there are no clever attacks on the algorithm itself (currently none are known for the SHA-2 hash family) this is what it takes to break the algorithm.

To get a feeling for what 2^256 actually means: currently it is believed that the number of atoms in the (entire!!!) universe is roughly 10^80 which is roughly 2^266. Assuming 32 byte input (which is reasonable for your case - 20 bytes salt + 12 bytes password) my machine takes ~0,22s (~2^-2s) for 65536 (=2^16) computations. So 2^256 computations would be done in 2^240 * 2^16 computations which would take

2^240 * 2^-2 = 2^238 ~ 10^72s ~ 3,17 * 10^64 years

Even calling this millions of years is ridiculous. And it doesn't get much better with the fastest hardware on the planet computing thousands of hashes in parallel. No human technology will be able to crunch this number into something acceptable.

So forget brute-forcing SHA-256 here. Your next question was about dictionary words. To retrieve such weak passwords rainbow tables were used traditionally. A rainbow table is generally just a table of precomputed hash values, the idea is if you were able to precompute and store every possible hash along with its input, then it would take you O(1) to look up a given hash and retrieve a valid preimage for it. Of course this is not possible in practice since there's no storage device that could store such enormous amounts of data. This dilemma is known as memory-time tradeoff. As you are only able to store so many values typical rainbow tables include some form of hash chaining with intermediary reduction functions (this is explained in detail in the Wikipedia article) to save on space by giving up a bit of savings in time.

Salts were a countermeasure to make such rainbow tables infeasible. To discourage attackers from precomputing a table for a specific salt it is recommended to apply per-user salt values. However, since users do not use secure, completely random passwords, it is still surprising how successful you can get if the salt is known and you just iterate over a large dictionary of common passwords in a simple trial and error scheme. The relationship between natural language and randomness is expressed as entropy. Typical password choices are generally of low entropy, whereas completely random values would contain a maximum of entropy.

The low entropy of typical passwords makes it possible that there is a relatively high chance of one of your users using a password from a relatively small database of common passwords. If you google for them, you will end up finding torrent links for such password databases, often in the gigabyte size category. Being successful with such a tool is usually in the range of minutes to days if the attacker is not restricted in any way.

That's why generally hashing and salting alone is not enough, you need to install other safety mechanisms as well. You should use an artificially slowed down entropy-enducing method such as PBKDF2 described in PKCS#5 and you should enforce a waiting period for a given user before they may retry entering their password. A good scheme is to start with 0.5s and then doubling that time for each failed attempt. In most cases users don't notice this and don't fail much more often than three times on average. But it will significantly slow down any malicious outsider trying to attack your application.

My way of solving this problem is placing all your actions with a specific prefix like "web" or "service" and configure that all url's with that prefix will be intercepted by the DispatcherServlet.

One set of familiar operations that you can do in MapReduce is the set of normal SQL operations: SELECT, SELECT WHERE, GROUP BY, ect.

Another good example is matrix multiply, where you pass one row of M and the entire vector x and compute one element of M * x.

One of the following solutions will work for you:

1. npm config set python c:\Python\27\python.exe or set PYTHON=D:\Python\bin\Python.exe
2. npm config set python D:\Library\Python\Python27\python.exe
3. Let npm configure everything for you (takes forever to complete) npm --add-python-to-path='true' --debug install --global windows-build-tools (Must be executed via "Run As Administrator" PowerShell)

If not... Try to install the required package on your own (I did so, and it was node-sass, after installing it manually, the whole npm install was successfully completed

This error can occur on anything that requires elevated privileges in Windows.

It happens when the "Application Information" service is disabled in Windows services. There are a few viruses that use this as an attack vector to prevent people from removing the virus. It also prevents people from installing software to remove viruses.

The normal way to fix this would be to run services.msc, or to go into Administrative Tools and run "Services". However, you will not be able to do that if the "Application Information" service is disabled.

Instead, reboot your computer into Safe Mode (reboot and press F8 until the Windows boot menu appears, select Safe Mode with Networking). Then run services.msc and look for services that are designated as "Disabled" in the Startup Type column. Change these "Disabled" services to "Automatic".

Make sure the "Application Information" service is set to a Startup Type of "Automatic".

When you are done enabling your services, click Ok at the bottom of the tool and reboot your computer back into normal mode. The problem should be resolved when Windows reboots.

You might not need jQuery for this task. FormData is a perfect solution for this.

Here is the code that use FormData to collect input values, and use dot-prop to transform the values into nested objects.

CodeSandbox Demo

Well, you are using both frame.setSize() and frame.pack().

You should use one of them at one time.

Using setSize() you can give the size of frame you want but if you use pack(), it will automatically change the size of the frames according to the size of components in it. It will not consider the size you have mentioned earlier.

Try removing frame.pack() from your code or putting it before setting size and then run it.

Here is quick and dirty color generator in C# (using 'RYB approach' described in this article). It's a rewrite from JavaScript.

Use:

List<Color> ColorPalette = ColorGenerator.Generate(30).ToList();

First two colors tend to be white and a shade of black. I often skip them like this (using Linq):

List<Color> ColorsPalette = ColorGenerator
            .Generate(30)
            .Skip(2) // skip white and black
            .ToList(); 

Implementation:

public static class ColorGenerator
{

    // RYB color space
    private static class RYB
    {
        private static readonly double[] White = { 1, 1, 1 };
        private static readonly double[] Red = { 1, 0, 0 };
        private static readonly double[] Yellow = { 1, 1, 0 };
        private static readonly double[] Blue = { 0.163, 0.373, 0.6 };
        private static readonly double[] Violet = { 0.5, 0, 0.5 };
        private static readonly double[] Green = { 0, 0.66, 0.2 };
        private static readonly double[] Orange = { 1, 0.5, 0 };
        private static readonly double[] Black = { 0.2, 0.094, 0.0 };

        public static double[] ToRgb(double r, double y, double b)
        {
            var rgb = new double[3];
            for (int i = 0; i < 3; i++)

In C++

using namespace std;

string my_string {"Hello world"};
string element_to_be_found {"Hello"};

if(my_string.find(element_to_be_found)!=string::npos)
   std::cout<<"Element Found"<<std::endl;

I realize this is a rather old question, but here's the solution I came up with today:

doSomethingToRequestData().then(function(downloadedFile) {
  // create a download anchor tag
  var downloadLink      = document.createElement('a');
  downloadLink.target   = '_blank';
  downloadLink.download = 'name_to_give_saved_file.pdf';

  // convert downloaded data to a Blob
  var blob = new Blob([downloadedFile.data], { type: 'application/pdf' });

  // create an object URL from the Blob
  var URL = window.URL || window.webkitURL;
  var downloadUrl = URL.createObjectURL(blob);

  // set object URL as the anchor's href
  downloadLink.href = downloadUrl;

  // append the anchor to document body
  document.body.append(downloadLink);

  // fire a click event on the anchor
  downloadLink.click();

  // cleanup: remove element and revoke object URL
  document.body.removeChild(downloadLink);
  URL.revokeObjectURL(downloadUrl);
}

DELETE FROM ... WHERE id=...;

protected function templateRemove($id){
            $em = $this->getDoctrine()->getManager();
            $entity = $em->getRepository('XXXBundle:Templates')->findOneBy(array('id' => $id));

            if ($entity != null){
                $em->remove($entity);
                $em->flush();
            }
        }

for a in soup("p",{'id':'pagination'})[0]("a",{'href': True}):
        if createunicode(a.text) in ['<','<']:
            links.append(a.attrMap['href'])
        else:
            continue

It works for me.

You can hang a lot of functions on the onClick event for one element. How can you be sure the false one will be the last one to fire? preventDefault on the other hand will definitely prevent only the default behavior of the element.

A possible alternative approach in Excel 2010 or later versions:

AGGREGATE(6,6,A1,B1)

In AGGREGATE function the first 6 indicates PRODUCT operation and the second 6 denotes "ignore errors"

[untested]

Another table that is useful is:

SELECT * FROM user_objects WHERE object_type='TRIGGER';

You can also use this to query views, indexes etc etc

The perldoc has a good definition of our.

Unlike my, which both allocates storage for a variable and associates a simple name with that storage for use within the current scope, our associates a simple name with a package variable in the current package, for use within the current scope. In other words, our has the same scoping rules as my, but does not necessarily create a variable.

The error already says what you have to do. MD5 operates on bytes, so you have to encode Unicode string into bytes, e.g. with line.encode('utf-8').

This worked for me:

grep  "\bsearch_word\b"  text_file > output.txt  ## \b indicates boundaries. This is much faster.

or,

grep -w "search_word" text_file > output.txt

I like to give the users a bit of flexibility and trust, that they will get the format right, but I do want to enforce only digits and two decimals for currency

^[$\-\s]*[\d\,]*?([\.]\d{0,2})?\s*$

Takes care of:

$ 1.
-$ 1.00
$ -1.0
.1
.10
-$ 1,000,000.0

Of course it will also match:

$$--$1,92,9,29.1 => anyway after cleanup => -192,929.10
