No it doesnt really matter. The MySQL speed is about 7 Million rows per second. So you can scale it quite a bit

I usually create a dictionary containing a DataFrame for every sheet:

xl_file = pd.ExcelFile(file_name)

dfs = {sheet_name: xl_file.parse(sheet_name) 
          for sheet_name in xl_file.sheet_names}

Update: In pandas version 0.21.0+ you will get this behavior more cleanly by passing sheet_name=None to read_excel:

dfs = pd.read_excel(file_name, sheet_name=None)

In 0.20 and prior, this was sheetname rather than sheet_name (this is now deprecated in favor of the above):

dfs = pd.read_excel(file_name, sheetname=None)

In Html you can add your input field with a date picker like this

<input class="form-control date-picker fromDates" id="myDate" type="text">

and then in java script, initialize your datepicker and set your value to the date like this,

$('.fromDates').datepicker({
                maxDate: '0',
                dateFormat: "dd/mm/yy",
                changeYear: true,
                changeMonth: true,
                yearRange: "-100:+0"
            });

var myDateVal = moment('${value}').format('DD/MM/YYYY');
$('#myDate').datepicker().datepicker('setDate', myDateVal );

(In here fromdate attribute shows the previous dates of the current date)

Completely reset?

1. Delete the .git directory locally.

2. Recreate the git repostory:

   $ cd (project-directory)
   $ git init
   $ (add some files)
   $ git add .
   $ git commit -m 'Initial commit'
   

3. Push to remote server, overwriting. Remember you're going to mess everyone else up doing this … you better be the only client.

   $ git remote add origin <url>
   $ git push --force --set-upstream origin master
   

We had this problem years ago before I had joined and had in place a solution that used local storage for user and environment information. Angular 1.0 days to be exact. We were formerly dynamically creating a js file at runtime that would then place the generated api urls into a global variable. We're a little more OOP driven these days and don't use local storage for anything.

I created a better solution for both determining environment and api url creation.

How does this differ?

The app will not load unless the config.json file is loaded. It uses factory functions to create a higher degree of SOC. I could encapsulate this into a service, but I never saw any reason when the only similarity between the different sections of the file are that they exist together in the file. Having a factory function allows me to pass the function directly into a module if it's capable of accepting a function. Last, I have an easier time setting up InjectionTokens when factory functions are available to utilize.

Downsides?

You're out of luck using this setup (and most of the other answers) if the module you want to configure doesn't allow a factory function to be passed into either forRoot() or forChild(), and there's no other way to configure the package by using a factory function.

Instructions

1. Using fetch to retrieve a json file, I store the object in window and raise a custom event. - remember to install whatwg-fetch and add it to your polyfills.ts for IE compatibility
2. Have an event listener listening for the custom event.
3. The event listener receives the event, retrieves the object from window to pass to an observable, and clears out what was stored in window.
4. Bootstrap Angular

-- This is where my solution starts to really differ --

5. Create a file exporting an interface whose structure represents your config.json -- it really helps with type consistency and the next section of code requires a type, and don't specify {} or any when you know you can specify something more concrete
6. Create the BehaviorSubject that you will pass the parsed json file into in step 3.
7. Use factory functions to reference the different sections of your config to maintain SOC
8. Create InjectionTokens for the providers needing the result of your factory functions

-- and/or --

9. Pass the factory functions directly into the modules capable of accepting a function in either its forRoot() or forChild() methods.

-- main.ts

I check window["environment"] is not populated before creating an event listener to allow the possiblilty of a solution where window["environment"] is populated by some other means before the code in main.ts ever executes.

import { enableProdMode } from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/app.module';
import { configurationSubject } from './app/utils/environment-resolver';

var configurationLoadedEvent = document.createEvent('Event');
configurationLoadedEvent.initEvent('config-set', true, true);
fetch("../../assets/config.json")
.then(result => { return result.json(); })
.then(data => {
  window["environment"] = data;
  document.dispatchEvent(configurationLoadedEvent);
}, error => window.location.reload());

/*
  angular-cli only loads the first thing it finds it needs a dependency under /app in main.ts when under local scope. 
  Make AppModule the first dependency it needs and the rest are done for ya. Event listeners are 
  ran at a higher level of scope bypassing the behavior of not loading AppModule when the 
  configurationSubject is referenced before calling platformBrowserDynamic().bootstrapModule(AppModule)

  example: this will not work because configurationSubject is the first dependency the compiler realizes that lives under 
  app and will ONLY load that dependency, making AppModule an empty object.

  if(window["environment"])
  {
    if (window["environment"].production) {
      enableProdMode();
    }
    configurationSubject.next(window["environment"]);
    platformBrowserDynamic().bootstrapModule(AppModule)
    .catch(err => console.log(err));
  }
*/
if(!window["environment"]) {
  document.addEventListener('config-set', function(e){
    if (window["environment"].production) {
      enableProdMode();
    }
    configurationSubject.next(window["environment"]);
    window["environment"] = undefined;
    platformBrowserDynamic().bootstrapModule(AppModule)
    .catch(err => console.log(err));
  });
}

--- environment-resolvers.ts

I assign a value to the BehaviorSubject using window["environment"] for redundancy. You could devise a solution where your config is preloaded already and window["environment"] is already populated by the time any of your Angular's app code is ran, including the code in main.ts

import { BehaviorSubject } from "rxjs";
import { IConfig } from "../config.interface";

const config = <IConfig>Object.assign({}, window["environment"]);
export const configurationSubject = new BehaviorSubject<IConfig>(config);
export function resolveEnvironment() {
  const env = configurationSubject.getValue().environment;
  let resolvedEnvironment = "";
  switch (env) {
 // case statements for determining whether this is dev, test, stage, or prod
  }
  return resolvedEnvironment;
}

export function resolveNgxLoggerConfig() {
  return configurationSubject.getValue().logging;
}

-- app.module.ts - Stripped down for easier understanding

Fun fact! Older versions of NGXLogger required you to pass in an object into LoggerModule.forRoot(). In fact, the LoggerModule still does! NGXLogger kindly exposes LoggerConfig which you can override allowing you to use a factory function for setup.

import { resolveEnvironment, resolveNgxLoggerConfig, resolveSomethingElse } from './environment-resolvers';
import { LoggerConfig } from 'ngx-logger';
@NgModule({
    modules: [
        SomeModule.forRoot(resolveSomethingElse)
    ],
    providers:[
        {
            provide: ENVIRONMENT,
            useFactory: resolveEnvironment
        },
        { 
            provide: LoggerConfig,
            useFactory: resolveNgxLoggerConfig
        }
    ]
})
export class AppModule

Addendum

How did I solve the creation of my API urls?

I wanted to be able to understand what each url did via a comment and wanted typechecking since that's TypeScript's greatest strength compared to javascript (IMO). I also wanted to create an experience for other devs to add new endpoints, and apis that was as seamless as possible.

I created a class that takes in the environment (dev, test, stage, prod, "", and etc) and passed this value to a series of classes[1-N] whose job is to create the base url for each API collection. Each ApiCollection is responsible for creating the base url for each collection of APIs. Could be our own APIs, a vendor's APIs, or even an external link. That class will pass the created base url into each subsequent api it contains. Read the code below to see a bare bones example. Once setup, it's very simple for another dev to add another endpoint to an Api class without having to touch anything else.

TLDR; basic OOP principles and lazy getters for memory optimization

@Injectable({
    providedIn: 'root'
})
export class ApiConfig {
    public apis: Apis;

    constructor(@Inject(ENVIRONMENT) private environment: string) {
        this.apis = new Apis(environment);
    }
}

export class Apis {
    readonly microservices: MicroserviceApiCollection;

    constructor(environment: string) {
        this.microservices = new MicroserviceApiCollection(environment);
    }
}

export abstract class ApiCollection {
  protected domain: any;

  constructor(environment: string) {
      const domain = this.resolveDomain(environment);
      Object.defineProperty(ApiCollection.prototype, 'domain', {
          get() {
              Object.defineProperty(this, 'domain', { value: domain });
              return this.domain;
          },
          configurable: true
      });
  }
}

export class MicroserviceApiCollection extends ApiCollection {
  public member: MemberApi;

  constructor(environment) {
      super(environment);
      this.member = new MemberApi(this.domain);
  }

  resolveDomain(environment: string): string {
      return `https://subdomain${environment}.actualdomain.com/`;
  }
}

export class Api {
  readonly base: any;

  constructor(baseUrl: string) {
      Object.defineProperty(this, 'base', {
          get() {
              Object.defineProperty(this, 'base',
              { value: baseUrl, configurable: true});
              return this.base;
          },
          enumerable: false,
          configurable: true
      });
  }

  attachProperty(name: string, value: any, enumerable?: boolean) {
      Object.defineProperty(this, name,
      { value, writable: false, configurable: true, enumerable: enumerable || true });
  }
}

export class MemberApi extends Api {

  /**
  * This comment will show up when referencing this.apiConfig.apis.microservices.member.memberInfo
  */
  get MemberInfo() {
    this.attachProperty("MemberInfo", `${this.base}basic-info`);
    return this.MemberInfo;
  }

  constructor(baseUrl: string) {
    super(baseUrl + "member/api/");
  }
}

in rare cases when you can't use strncat, strcat or strcpy. And you don't have access to <string.h> so you can't use strlen. Also you maybe don't even know the size of the char arrays and you still want to concatenate because you got only pointers. Well, you can do old school malloc and count characters yourself like..

char *combineStrings(char* inputA, char* inputB) {
    size_t len = 0, lenB = 0;
    while(inputA[len] != '\0') len++;
    while(inputB[lenB] != '\0') lenB++;
    char* output = malloc(len+lenB);
    sprintf((char*)output,"%s%s",inputA,inputB);
    return output;
}

It just needs #include <stdio.h> which you will have most likely included already

WARNING: This will remove the database

Use command:

rm -rf /usr/local/var/postgres && initdb /usr/local/var/postgres -E utf8

You can also use batch functions for this:

@echo off
setlocal 

goto MAIN
::-----------------------------------------------
:: "%~f2" get abs path of %~2. 
::"%~fs2" get abs path with short names of %~2.
:setAbsPath
  setlocal
  set __absPath=%~f2
  endlocal && set %1=%__absPath%
  goto :eof
::-----------------------------------------------

:MAIN
call :setAbsPath ABS_PATH ..\
echo %ABS_PATH%

endlocal

To catch all possible exceptions, catch BaseException. It's on top of the Exception hierarchy:

Python 3: https://docs.python.org/3.9/library/exceptions.html#exception-hierarchy

Python 2.7: https://docs.python.org/2.7/library/exceptions.html#exception-hierarchy

try:
    something()
except BaseException as error:
    print('An exception occurred: {}'.format(error))

But as other people mentioned, you would usually not need this, only for specific cases.

Here's an update to what Richard did that adds a "depth" indicator. The output is level-0, level-1, level-2, etc.

class UL_Class_Walker extends Walker_Nav_Menu {
  function start_lvl(&$output, $depth) {
    $indent = str_repeat("\t", $depth);
    $output .= "\n$indent<ul class=\"level-".$depth."\">\n";
  }
}

You can always look at how wide your font is and take the average character pixel size. Then just multiply that by the number of characters you want. It's a bit tacky but it works as a quick fix.

You can do it like... Just give the proper path of your json file...

<!doctype html>
<html>
    <head>
        <script type="text/javascript" src="abc.json"></script>
             <script type="text/javascript" >
                function load() {
                     var mydata = JSON.parse(data);
                     alert(mydata.length);

                     var div = document.getElementById('data');

                     for(var i = 0;i < mydata.length; i++)
                     {
                        div.innerHTML = div.innerHTML + "<p class='inner' id="+i+">"+ mydata[i].name +"</p>" + "<br>";
                     }
                 }
        </script>
    </head>
    <body onload="load()">
    <div id= "data">

    </div>
    </body>
</html>

Simply getting the data and appending it to a div... Initially printing the length in alert.

Here is my Json file: abc.json

data = '[{"name" : "Riyaz"},{"name" : "Javed"},{"name" : "Arun"},{"name" : "Sunil"},{"name" : "Rahul"},{"name" : "Anita"}]';

Set your PYTHONPATH environment variable. For example like this PYTHONPATH=.:.. (for *nix family).

Also you can manually add your current directory (src in your case) to pythonpath:

import os
import sys
sys.path.insert(0, os.getcwd())

Yeah, no checkbox for you in iOS (-:

Here, this is what I did to create a checkbox:

UIButton *checkbox;
BOOL checkBoxSelected;
checkbox = [[UIButton alloc] initWithFrame:CGRectMake(x,y,20,20)];
// 20x20 is the size of the checkbox that you want
// create 2 images sizes 20x20 , one empty square and
// another of the same square with the checkmark in it
// Create 2 UIImages with these new images, then:

[checkbox setBackgroundImage:[UIImage imageNamed:@"notselectedcheckbox.png"]
                    forState:UIControlStateNormal];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateSelected];
[checkbox setBackgroundImage:[UIImage imageNamed:@"selectedcheckbox.png"]
                    forState:UIControlStateHighlighted];
checkbox.adjustsImageWhenHighlighted=YES;
[checkbox addTarget:(nullable id) action:(nonnull SEL) forControlEvents:(UIControlEvents)];
[self.view addSubview:checkbox];

Now in the target method do the following:

-(void)checkboxSelected:(id)sender
{
    checkBoxSelected = !checkBoxSelected; /* Toggle */
    [checkbox setSelected:checkBoxSelected];
}

That's it!

Basically I use Fiddler or Postman for testing API's.

In fiddler, in request header you need to specify instead of xml, html you need to change it to json. Eg: Accept: application/json. That should do the job.

You are using Python 2 for which the input() function tries to evaluate the expression entered. Because you enter a string, Python treats it as a name and tries to evaluate it. If there is no variable defined with that name you will get a NameError exception.

To fix the problem, in Python 2, you can use raw_input(). This returns the string entered by the user and does not attempt to evaluate it.

Note that if you were using Python 3, input() behaves the same as raw_input() does in Python 2.

You can use Array.prototype.find function in javascript. Array find MDN.

So to find string in array of string, the code becomes very simple. Plus as browser implementation, it will provide good performance.

Ex.

var strs = ['abc', 'def', 'ghi', 'jkl', 'mno'];
var value = 'abc';
strs.find(
    function(str) {
        return str == value;
    }
);

or using lambda expression it will become much shorter

var strs = ['abc', 'def', 'ghi', 'jkl', 'mno'];
var value = 'abc';
strs.find((str) => str === value);

Using pairwise from rxjx you can achieve this easier. import { filter,pairwise } from 'rxjs/operators';

previousUrl: string;
constructor(router: Router) {
router.events
  .pipe(filter((evt: any) => evt instanceof RoutesRecognized), pairwise())
  .subscribe((events: RoutesRecognized[]) => {
  console.log('previous url', events[0].urlAfterRedirects);
  console.log('current url', events[1].urlAfterRedirects);
  this.previousUrl = events[0].urlAfterRedirects;
});

}

public interface IMinStack<T extends Comparable<T>> {
  public void push(T val);
  public T pop();
  public T minValue();
  public int size();
}

import java.util.Stack;

public class MinStack<T extends Comparable<T>> implements IMinStack<T> {
  private Stack<T> stack = new Stack<T>();
  private Stack<T> minStack = new Stack<T>();

  @Override
  public void push(T val) {
    stack.push(val);
    if (minStack.isEmpty() || val.compareTo(minStack.peek()) < 0)
        minStack.push(val);
  }

  @Override
  public T pop() {
    T val = stack.pop();
    if ((false == minStack.isEmpty())
            && val.compareTo(minStack.peek()) == 0)
        minStack.pop();
    return val;
  }

  @Override
  public T minValue() {
    return minStack.peek();
  }

  @Override
  public int size() {
    return stack.size();
  }
}

For me was because I put the animation name inside square brackets.

<div [@animation]></div>

But after I removed the bracket all worked fine (In Angular 9.0.1):

<div @animation></div>

So, your input is 'dan|warrior|54' and you want "warrior". You do this like so:

>>> dan = 'dan|warrior|54'
>>> dan.split('|')[1]
"warrior"

As a heads up to others, I've oberserved that at least as manifested by TypeScript compiled by WebPack for Angular 2, you quietly get overWRITTEN instead of overLOADED methods.

myComponent {
  method(): { console.info("no args"); },
  method(arg): { console.info("with arg"); }
}

Calling:

myComponent.method()

seems to execute the method with arguments, silently ignoring the no-arg version, with output:

with arg

Something like:

File file = new File("C:\\user\\Desktop\\dir1\\dir2\\filename.txt");
file.getParentFile().mkdirs();
FileWriter writer = new FileWriter(file);

I really think you should adopt Smarty template engine as a standard php lib for your projects.

while doing performance testing, the measure i go by is RPS, that is how many requests per second can the server serve within acceptable latency.

theoretically one server can only run as many requests concurrently as number of cores on it..

It doesn't look like the problem is ASP.net's threading model, since it can potentially serve thousands of rps. It seems like the problem might be your application. Are you using any synchronization primitives ?

also whats the latency on your web services, are they very quick to respond (within microseconds), if not then you might want to consider asynchronous calls, so you dont end up blocking

If this doesnt yeild something, then you might want to profile your code using visual studio or redgate profiler

You can open the facebook app on button click as follows:-

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

    this.findViewById(R.id.button1).setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {

            startNewActivity("com.facebook.katana");
        }
    });

}

public void startNewActivity( String packageName)
{
    Intent intent = MainActivity.this.getPackageManager().getLaunchIntentForPackage(packageName);
    if (intent != null)
    {
        // we found the activity
        // now start the activity
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        startActivity(intent);
    }
    else
    {
        // bring user to the market
        // or let them choose an app?
        intent = new Intent(Intent.ACTION_VIEW);
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        intent.setData(Uri.parse("market://details?id="+packageName));
        startActivity(intent);

Use python's csv module for reading and writing comma or tab-delimited files. The csv module is preferred because it gives you good control over quoting.

For example, here is the worked example for you:

import csv
data = ["value %d" % i for i in range(1,4)]

out = csv.writer(open("myfile.csv","w"), delimiter=',',quoting=csv.QUOTE_ALL)
out.writerow(data)

Produces:

"value 1","value 2","value 3"

This method will get properties of the class and compare the values for each property. If any of the values are different, it will return false, else it will return true.

public static bool Compare<T>(T Object1, T object2)
{
    //Get the type of the object
    Type type = typeof(T);

    //return false if any of the object is false
    if (Object1 == null || object2 == null)
        return false;

    //Loop through each properties inside class and get values for the property from both the objects and compare
    foreach (System.Reflection.PropertyInfo property in type.GetProperties())
    {
        if (property.Name != "ExtensionData")
        {
            string Object1Value = string.Empty;
            string Object2Value = string.Empty;
            if (type.GetProperty(property.Name).GetValue(Object1, null) != null)
                Object1Value = type.GetProperty(property.Name).GetValue(Object1, null).ToString();
            if (type.GetProperty(property.Name).GetValue(object2, null) != null)
                Object2Value = type.GetProperty(property.Name).GetValue(object2, null).ToString();
            if (Object1Value.Trim() != Object2Value.Trim())
            {
                return false;
            }
        }
    }
    return true;
}

Usage:

bool isEqual = Compare<Employee>(Object1, Object2)

I'm using Angular 5.

In my case, I needed to import ReactiveFormsModule too.

File app.module.ts (or anymodule.module.ts):

import { FormsModule, ReactiveFormsModule } from '@angular/forms';

@NgModule({
  imports: [
    CommonModule,
    FormsModule,
    ReactiveFormsModule
  ],

I had same problem and after three hour struggling I find out what's going on

In my case, when I wanted to migrate for the first time in up() method, the default code wants to create the tables that already existed so I got same error as you

To solve it, just delete those code and write want you want. For example, I wanted to add a column so i just write

migrationBuilder.AddColumn<string>(
            name: "fieldName",
            table: "tableName",
            nullable: true);

First of all you should use double "==" instead of "=" to compare two values. Using "=" You assigning value to variable in this case "somevar"

I also have the same error. I have updated the jackson library version and error has gone.

<!-- Jackson to convert Java object to Json -->
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.9.4</version>
        </dependency>

        <dependency>

            <version>2.9.4</version>
        </dependency>
    </dependencies>

and also check your data classes that have you created getters and setters for all the properties.

Below is a solution for WINDOWS ONLY

In cases where the application (like Tomcat) is started as a windows service, the System.getProperty("user.name") or System.getenv().get("USERNAME") return the user who started the service and not the current logged in user name.

Also in Java 9 the NTSystem etc classes will not be accessible

So workaround for windows: You can use wmic, so you have to run the below command

wmic ComputerSystem get UserName

If available, this will return output of the form:

UserName
{domain}\{logged-in-user-name}

Note: For windows you need to use cmd /c as a prefix, so below is a crude program as an example:

    Process exec = Runtime.getRuntime().exec("cmd /c wmic ComputerSystem get UserName".split(" "));
    System.out.println(exec.waitFor());
    try (BufferedReader bw = new BufferedReader(new InputStreamReader(exec.getInputStream()))) {
        System.out.println(bw.readLine() + "\n" + bw.readLine()+ "\n" + bw.readLine());
    }

SHA1 is a cryptographic hash function, so the intention of the design was to avoid what you are trying to do.

However, breaking a SHA1 hash is technically possible. You can do so by just trying to guess what was hashed. This brute-force approach is of course not efficient, but that's pretty much the only way.

So to answer your question: yes, it is possible, but you need significant computing power. Some researchers estimate that it costs $70k - $120k.

As far as we can tell today, there is also no other way but to guess the hashed input. This is because operations such as mod eliminate information from your input. Suppose you calculate mod 5 and you get 0. What was the input? Was it 0, 5 or 500? You see, you can't really 'go back' in this case.

I tried everything and nothing worked for me, I ended up using displaying my data frame as HTML as follows

from IPython.display import HTML    
HTML (pd.to_html())

It is because you are in a try statement. Since there could be an error, sum might not get initialized, so put your return statement in the finally block, that way it will for sure be returned.

Make sure that you initialize sum outside the try/catch/finally so that it is in scope.

Set the href attribute with

$(selector).attr('href', 'url_goes_here');

and read it using

$(selector).attr('href');

Where "selector" is any valid jQuery selector for your <a> element (".myClass" or "#myId" to name the most simple ones).

Hope this helps !

You can try this:

//Your class instance
Publication publication = new Publication();

//Get class with full path(with package name)
Class<?> c = Class.forName("com.example.publication.models.Publication");

//Get method
Method  method = c.getDeclaredMethod ("setTitle", String.class);

//set value
method.invoke (publication,  "Value to want to set here...");

You can do this using the market:// prefix.

Java

final String appPackageName = getPackageName(); // getPackageName() from Context or Activity object
try {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));
} catch (android.content.ActivityNotFoundException anfe) {
    startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=" + appPackageName)));
}

Kotlin

try {
    startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=$packageName")))
} catch (e: ActivityNotFoundException) {
    startActivity(Intent(Intent.ACTION_VIEW, Uri.parse("https://play.google.com/store/apps/details?id=$packageName")))
}

We use a try/catch block here because an Exception will be thrown if the Play Store is not installed on the target device.

NOTE: any app can register as capable of handling the market://details?id=<appId> Uri, if you want to specifically target Google Play check the Berták answer

List<WebElement> myElements = driver.findElements(By.xpath("some/path//a"));
        System.out.println("Size of List: "+myElements.size());
        for(WebElement e : myElements) 
        {        
            System.out.print("Text within the Anchor tab"+e.getText()+"\t");
            System.out.println("Anchor: "+e.getAttribute("href"));
        }

//NOTE: "//a" will give you all the anchors there on after the point your XPATH has reached.

For simplicity and brevity:

$ cat Makefile
check-%:
        @: $(if $(value $*),,$(error $* is undefined))

bar:| check-foo
        echo "foo is $$foo"

With outputs:

$ make bar
Makefile:2: *** foo is undefined. Stop.
$ make bar foo="something"
echo "foo is $$foo"
foo is something

The currently-accepted answer to this question is wrong. C11 6.9.2/2:

If a translation unit contains one or more tentative definitions for an identifier, and the translation unit contains no external definition for that identifier, then the behavior is exactly as if the translation unit contains a file scope declaration of that identifier, with the composite type as of the end of the translation unit, with an initializer equal to 0.

So the original code in the question behaves as if file1.c and file2.c each contained the line int i = 0; at the end, which causes undefined behaviour due to multiple external definitions (6.9/5).

Since this is a Semantic rule and not a Constraint, no diagnostic is required.

Here are two more questions about the same code with correct answers:

• Tentative definitions in C and linking
• How do I use extern to share variables between source files?

In Rails 4.x (See http://edgeguides.rubyonrails.org/active_record_querying.html#not-conditions)

GroupUser.where.not(user_id: me)

In Rails 3.x

GroupUser.where(GroupUser.arel_table[:user_id].not_eq(me))

To shorten the length, you could store GroupUser.arel_table in a variable or if using inside the model GroupUser itself e.g., in a scope, you can use arel_table[:user_id] instead of GroupUser.arel_table[:user_id]

_{Rails 4.0 syntax credit to @jbearden's answer}

You can use strncat()

#include <stdio.h>
#include <string.h>

int main(void){
  char hi[6];
  char ch = '!';
  strcpy(hi, "hello");

  strncat(hi, &ch, 1);
  printf("%s\n", hi);
}

List<User> findByUsernameContainingIgnoreCase(String username);

in order to ignore case issues

To update one column here are some syntax options:

Option 1

var ls=new int[]{2,3,4};
using (var db=new SomeDatabaseContext())
{
    var some= db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList();
    some.ForEach(a=>a.status=true);
    db.SubmitChanges();
}

Option 2

using (var db=new SomeDatabaseContext())
{
     db.SomeTable
       .Where(x=>ls.Contains(x.friendid))
       .ToList()
       .ForEach(a=>a.status=true);

     db.SubmitChanges();
}

Option 3

using (var db=new SomeDatabaseContext())
{
    foreach (var some in db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList())
    {
        some.status=true;
    }
    db.SubmitChanges();
}

Update

As requested in the comment it might make sense to show how to update multiple columns. So let's say for the purpose of this exercise that we want not just to update the status at ones. We want to update name and status where the friendid is matching. Here are some syntax options for that:

Option 1

var ls=new int[]{2,3,4};
var name="Foo";
using (var db=new SomeDatabaseContext())
{
    var some= db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList();
    some.ForEach(a=>
                    {
                        a.status=true;
                        a.name=name;
                    }
                );
    db.SubmitChanges();
}

Option 2

using (var db=new SomeDatabaseContext())
{
    db.SomeTable
        .Where(x=>ls.Contains(x.friendid))
        .ToList()
        .ForEach(a=>
                    {
                        a.status=true;
                        a.name=name;
                    }
                );
    db.SubmitChanges();
}

Option 3

using (var db=new SomeDatabaseContext())
{
    foreach (var some in db.SomeTable.Where(x=>ls.Contains(x.friendid)).ToList())
    {
        some.status=true;
        some.name=name;
    }
    db.SubmitChanges();
}

Update 2

In the answer I was using LINQ to SQL and in that case to commit to the database the usage is:

db.SubmitChanges();

But for Entity Framework to commit the changes it is:

db.SaveChanges()

your_dict = {}

To add new key:

1. your_dict[key]=value

2. your_dict.update(key=value)

I know this is a really old question but I wanted to add a bit of explanation that I discovered the hard way (this is n00b information).

"Basic Authentication" shares the same accounts that you have on your local computer or network. If you leave the domain and realm empty, local accounts are what are actually being used. So to add a new account you follow the exact process you would for adding a normal new user account to your local computer (as answered by JoshM or shown here). If you enter a domain and realm you can create network accounts in your local active directory and these are what will be used to log the user in and out.

Because it has been around for so long, basic authentication is generally compatible with any browser/system out there but it does have to major flaws:

• user and password are sent in the clear (except over SSL)
• you need to have a user account for each user or client

For more information about basic authentication or user accounts see the following MSDN page.

Interesting/funny way to do this using parameter expansion (requires bash 4.4 or newer):

${parameter@operator} - P operator

The expansion is a string that is the result of expanding the value of parameter as if it were a prompt string.

$ show_time() { local format='\D{%Y%m%d%H%M%S}'; echo "${format@P}"; }
$ show_time

I suggest using DateUtils from apache.commons library.

long millis = DateUtils.truncate(utilDate, Calendar.MILLISECOND).getTime();
java.sql.Timestamp sq = new java.sql.Timestamp(millis );

Edit: Fixed Calendar.MILISECOND to Calendar.MILLISECOND

I just installed MySQL Server 5.7 on Windows 10 and my.ini file is located here c:\ProgramData\MySQL\MySQL Server 5.7\my.ini.

The Data folder (where your dbs are created) is here C:/ProgramData/MySQL/MySQL Server 5.7\Data.

On a Mac-OS system

1. If you have used an installer, you can uninstall golang by using the same installer.
2. If you have installed from source

   rm -rf /usr/local/go
   rm -rf $(echo $GOPATH)
   

Then, remove all entries related to go i.e. GOROOT, GOPATH from ~/.bash_profile and run

source ~/.bash_profile

On a Linux system

rm -rf /usr/local/go
rm -rf $(echo $GOPATH)

Then, remove all entries related to go i.e. GOROOT, GOPATH from ~/.bashrc and run

source ~/.bashrc

you can remove the outer loop and replace this with data.data:

$.each(data.data, function(k, v) {
    /// do stuff
});

You were close:

$.each(data, function() {
  $.each(this, function(k, v) {
    /// do stuff
  });
});

You have an array of objects/maps so the outer loop iterates over those. The inner loop iterates over the properties on each object element.

You could use the Python bindings to libmagic, python-magic and then check the mime types. This won't tell you if the files are corrupted or intact but it should be able to determine what type of image it is.

You can try this code:

USE AdventureWorks2012;
GO
SET STATISTICS TIME ON;
GO
SELECT ProductID, StartDate, EndDate, StandardCost 
FROM Production.ProductCostHistory
WHERE StandardCost < 500.00;
GO
SET STATISTICS TIME OFF;
GO

Remove the public keyword from int[] locations={1,2,3};. An access modifier isn't allowed inside a method, as its accessbility is defined by its method scope.

If your goal is to use this reference in many a method, you might want to move the declaration outside the method.

C# 7 adds support for local functions

Here is the previous example using a local function

void Method()
{
    string localFunction(string source)
    {
        // add your functionality here
        return source ;
    };

   // call the inline function
   localFunction("prefix");
}

Here's my setup: I am on Ubuntu 9.10.

Now, Here's what I did.

1. Create a folder named "tomcat6-myapp" in /usr/share.
2. Create a folder "myapp" under /usr/share/tomcat6-myapp.
3. Copy the HTML file (that I need to deploy) to /usr/share/tomcat6-myapp/myapp. It must be named index.html.
4. Go to /etc/tomcat6/Catalina/localhost.

5. Create an xml file "myapp.xml" (i guess it must have the same name as the name of the folder in step 2) inside /etc/tomcat6/Catalina/localhost with the following contents.

   < Context path="/myapp" docBase="/usr/share/tomcat6-myapp/myapp" />
   

6. This xml is called the 'Deployment Descriptor' which Tomcat reads and automatically deploys your app named "myapp".

7. Now go to http://localhost:8080/myapp in your browser - the index.html gets picked up by tomcat and is shown.

I hope this helps!

import glob

jpgFilenamesList = glob.glob('145592*.jpg')

See glob in python documenttion

try creating a memory global variable storing the selection, then the other function can access the variable and do a paste for example..

var memory = '';//outside the functions but within the script tag.

function moz_stringCopy(DOMEle,firstPos,secondPos) {

var copiedString = DOMEle.value.slice(firstPos, secondPos);
memory = copiedString;

}

function moz_stringPaste(DOMEle, newpos) {

    DOMEle.value = DOMEle.value.slice(0,newpos) + memory + DOMEle.value.slice(newpos);

}

Application Pool recycling restarts the w3wp.exe process for that application pool, hence it will only affect web sites running in that application pool.

IISReset restarts ALL w3wp.exe processes and any other IIS related service, i.e. the NNTP or FTP Service.

I think changing web.config or /bin does not recycle the whole application pool, but I'm not sure on that.

No, don't spoil it with a break. This is the last remaining stronghold for the use of goto.

In this case a loop will also do the job (and is usually sufficiently fast).

a <- array(0, dim=dim(X))
for (i in 1:ncol(X)) {a[,i] <- X[,i]}

Your return is useless if you don't assign it

list=defineAList()

C++ has no built-in concepts of interfaces. You can implement it using abstract classes which contains only pure virtual functions. Since it allows multiple inheritance, you can inherit this class to create another class which will then contain this interface (I mean, object interface :) ) in it.

An example would be something like this -

class Interface
{
public:
    Interface(){}
    virtual ~Interface(){}
    virtual void method1() = 0;    // "= 0" part makes this method pure virtual, and
                                   // also makes this class abstract.
    virtual void method2() = 0;
};

class Concrete : public Interface
{
private:
    int myMember;

public:
    Concrete(){}
    ~Concrete(){}
    void method1();
    void method2();
};

// Provide implementation for the first method
void Concrete::method1()
{
    // Your implementation
}

// Provide implementation for the second method
void Concrete::method2()
{
    // Your implementation
}

int main(void)
{
    Interface *f = new Concrete();

    f->method1();
    f->method2();

    delete f;

    return 0;
}

  SELECT * INTO newtable FROM oldtable where 1=2

Where 1=2 is used when you need to copy the complete structure of a table without copying the data.

 SELECT * INTO newtable FROM oldtable 

To create a table with data you can use this statement.

Quoting http://php.net/manual/en/intro.mssql.php:

The MSSQL extension is not available anymore on Windows with PHP 5.3 or later. SQLSRV, an alternative driver for MS SQL is available from Microsoft: » http://msdn.microsoft.com/en-us/sqlserver/ff657782.aspx.

Once you downloaded that, follow the instructions at this page:

• Loading the Microsoft Drivers for PHP for SQL Server

In a nutshell:

Put the driver file in your PHP extension directory.
Modify the php.ini file to include the driver. For example:

extension=php_sqlsrv_53_nts_vc9.dll  

Restart the Web server.

See Also (copied from that page)

• System Requirements (Microsoft Drivers for PHP for SQL Server)
• Getting Started
• Programming Guide
• SQLSRV Driver API Reference (Microsoft Drivers for PHP for SQL Server)

The PHP Manual for the SQLSRV extension is located at http://php.net/manual/en/sqlsrv.installation.php and offers the following for Installation:

The SQLSRV extension is enabled by adding appropriate DLL file to your PHP extension directory and the corresponding entry to the php.ini file. The SQLSRV download comes with several driver files. Which driver file you use will depend on 3 factors: the PHP version you are using, whether you are using thread-safe or non-thread-safe PHP, and whether your PHP installation was compiled with the VC6 or VC9 compiler. For example, if you are running PHP 5.3, you are using non-thread-safe PHP, and your PHP installation was compiled with the VC9 compiler, you should use the php_sqlsrv_53_nts_vc9.dll file. (You should use a non-thread-safe version compiled with the VC9 compiler if you are using IIS as your web server). If you are running PHP 5.2, you are using thread-safe PHP, and your PHP installation was compiled with the VC6 compiler, you should use the php_sqlsrv_52_ts_vc6.dll file.

The drivers can also be used with PDO.

It was the service issue from the git. The site will be under maintenance. Please try once after the maintenance work is done.

 for(int i = 0; i < strlen(Name); i++ )
{
    if(Name[i] == '\n') Name[i] = '\0';
}

You should give it a try. This code basically loop through the string until it finds the '\n'. When it's found the '\n' will be replaced by the null character terminator '\0'

Note that you are comparing characters and not strings in this line, then there's no need to use strcmp():

if(Name[i] == '\n') Name[i] = '\0';

since you will be using single quotes and not double quotes. Here's a link about single vs double quotes if you want to know more

Swift 3

Bold:

let bondFont = UIFont.boldSystemFont(ofSize:UIFont.labelFontSize)

Italic:

let italicFont = UIFont.italicSystemFont(ofSize:UIFont.labelFontSize)

I just ran into this problem this morning and seemed very strange since my application was working fine up until today. I was getting the exact same "The Google Play services resources were not found..." message.

I tried opening the regular Google Maps application to see if I could get my location, but it wouldn't find it. Even after waiting 5 minutes, which is more than enough time to normally get a location from even the service provider via cell tower. So I checked Location Services.

Anyway, the problem turned out to be that on my S3 under Location Services -> Google Location Services. It was not checked. The other two location options were checked (VZW Location Services and Standalone GPS Services), but the last one, Google Location Services was not. After turning that on, the regular Google Maps could find my location and my application could find my location and the problem went away.

The error message pops up due to:

mMap.setMyLocationEnabled(true);

when Google Location Services is not enabled.

After doing some more testing it looks like if the current location is null (cannot be determined from all sources) then you will get this error when trying to turn on setMyLocationEnabled.

In most cases simply switching the virtual machine network adapter to bridged mode is enough to make the guest machine accessible from outside.

Sometimes it's possible for the guest machine to not automatically receive an IP which matches the host's IP range after switching to bridged mode (even after rebooting the guest machine). This is often caused by a malfunctioning or badly configured DHCP on the host network.

For example, if the host IP is 192.168.1.1 the guest machine needs to have an IP in the format 192.168.1.* where only the last group of numbers is allowed to be different from the host IP.

You can use a terminal (shell) and type ifconfig (ipconfig for Windows guests) to check what IP is assigned to the guest machine and change it if required.

If the host and guest IPs do not match simply setting a static IP for the guest machine explicitly should resolve the issue.

Try using json_encode on the string prior to using json_decode... idk if will work for you but it did for me... I'm using laravel 4 ajaxing through a route param.

$username = "{username: john}";
public function getAjaxSearchName($username)
{
    $username = json_encode($username);
    die(var_dump(json_decode($username, true)));
}

If you are using AngularJS, and you are using Angular Bootstrap : https://angular-ui.github.io/bootstrap/

You can do this so nice like this :

HTML:

<nav id="header-navbar" class="navbar navbar-default" ng-class="{'navbar-fixed-top':scrollDown}" role="navigation" scroll-nav>
    <div class="container-fluid top-header">
        <!--- Rest of code --->
    </div>
</nav>

CSS: (Note here I use padding as bigger nav to shrink without padding you can modify as you want)

nav.navbar {
  -webkit-transition: all 0.4s ease;
  transition: all 0.4s ease;

  background-color: white;
  margin-bottom: 0;
  padding: 25px;
}

.navbar-fixed-top {
  padding: 0;
}

And then add your directive

Directive: (Note you may need to change this.pageYOffset >= 50 from 50 to more or less to fulfill your needs)

angular.module('app')
.directive('scrollNav', function ($window) {
  return function(scope, element, attrs) {
    angular.element($window).bind("scroll", function() {
      if (this.pageYOffset >= 50) {
        scope.scrollDown = true;
      } else {
        scope.scrollDown = false;
      }
      scope.$apply();
    });
  };
});

This will do the job nicely, animated and cool way.

After checking the permission of the folder, it is okay with 744. I had the problem with a plugin that is installed on my WordPress site. The plugin has hooked that are in the corn job I suspected.

With a simple sudo it can fix the issue

sudo git pull origin master

You have it working.

if anyone needs this for NGINX configuration file here is the snippet:

location ~* \.(js|css|xml|gz)$ {
    add_header Vary "Accept-Encoding";
    (... other headers or rules ...)
}

$(document).ready(my_function);

Or

$(document).ready(function () {
  // Function code here.
});

Or the shorter but less readable variant:

$(my_function);

All of these will cause my_function to be called after the DOM loads.

See the ready event documentation for more details.

Binds a function to be executed whenever the DOM is ready to be traversed and manipulated.

Edit:

To simulate a click, use the click() method without arguments:

$('#button').click();

From the docs:

Triggers the click event of each matched element. Causes all of the functions that have been bound to that click event to be executed.

To put it all together, the following code simulates a click when the document finishes loading:

$(function () {
  $('#button').click();
});

Code that appends a list of parameters to an existing url using ES6 and jQuery:

class UrlBuilder {
    static appendParametersToUrl(baseUrl, listOfParams) {

        if (jQuery.isEmptyObject(listOfParams)) {
            return baseUrl;
        }

        const newParams = jQuery.param(listOfParams);

        let partsWithHash = baseUrl.split('#');
        let partsWithParams = partsWithHash[0].split('?');

        let previousParams = '?' + ((partsWithParams.length === 2) ? partsWithParams[1] + '&' : '');
        let previousHash = (partsWithHash.length === 2) ? '#' + partsWithHash[1] : '';

        return partsWithParams[0] + previousParams + newParams + previousHash;
    }
}

Where listOfParams is like

const listOfParams = {
    'name_1': 'value_1',
    'name_2': 'value_2',
    'name_N': 'value_N',
};

Example of Usage:

    UrlBuilder.appendParametersToUrl(urlBase, listOfParams);

Fast tests:

    url = 'http://hello.world';
    console.log('=> ', UrlParameters.appendParametersToUrl(url, null));
    // Output:  http://hello.world

    url = 'http://hello.world#h1';
    console.log('=> ', UrlParameters.appendParametersToUrl(url, null));
    // Output:  http://hello.world#h1

    url = 'http://hello.world';
    params = {'p1': 'v1', 'p2': 'v2'};
    console.log('=> ', UrlParameters.appendParametersToUrl(url, params));
    // Output: http://hello.world?p1=v1&p2=v2

    url = 'http://hello.world?p0=v0';
    params = {'p1': 'v1', 'p2': 'v2'};
    console.log('=> ', UrlParameters.appendParametersToUrl(url, params));
    // Output: http://hello.world?p0=v0&p1=v1&p2=v2

    url = 'http://hello.world#h1';
    params = {'p1': 'v1', 'p2': 'v2'};
    console.log('=> ', UrlParameters.appendParametersToUrl(url, params));
   // Output: http://hello.world?p1=v1&p2=v2#h1

    url = 'http://hello.world?p0=v0#h1';
    params = {'p1': 'v1', 'p2': 'v2'};
    console.log('=> ', UrlParameters.appendParametersToUrl(url, params));
    // Output: http://hello.world?p0=v0&p1=v1&p2=v2#h1

You can temporarily increase the cache size and do one dummy select and then reset the cache size back to 1. So for example

ALTER SEQUENCE mysequence INCREMENT BY 100;

select mysequence.nextval from dual;

ALTER SEQUENCE mysequence INCREMENT BY 1;

No there's not and developers still don't know why google doesn't pay attention to this request!

As you can see in this link it's one of the most popular issues with many stars in google code but still no response from google! You can also add stars to this issue, maybe google hears that!

1. Use a single body parameter within the mailto string
2. Use %0D%0A as newline

The mailto URI Scheme is specified by by RFC2368 (July 1998) and RFC6068 (October 2010).
Below is an extract of section 5 of this last RFC:

[...] line breaks in the body of a message MUST be encoded with "%0D%0A".
Implementations MAY add a final line break to the body of a message even if there is no trailing "%0D%0A" in the body [...]

See also in section 6 the example from the same RFC:

<mailto:[email protected]?body=send%20current-issue%0D%0Asend%20index>

The above mailto body corresponds to:

send current-issue
send index

AlliterativeAlice's example helped me tremendously. In my case, though, the server I was talking to didn't like having single quotes around utf-8 in the content type. It failed with a generic "Server Error" and it took hours to figure out what it didn't like:

request.ContentType = "text/xml; encoding=utf-8";

explode is an alternative. However, if you meant to split through a regular expression, the alternative is preg_split instead.

It would be this

array=($(ls -d */))

EDIT: See Gordon Davisson's solution for a more general answer (i.e. if your filenames contain special characters). This answer is merely a syntax correction.

An APK is just in zip format. You can unzip it like any other .zip file.

You can decompile .dex files using the dexdump tool, which is provided in the Android SDK.

See https://stackoverflow.com/a/7750547/116938 for more dex info.

This is an array of the command line switches pass to the program. E.g. if you start the program with the command "myapp.exe -c -d" then string[] args[] will contain the strings "-c" and "-d".

Yes, it prints GARBAGE unless you are lucky.

VERY IMPORTANT.

The type of the printf/sprintf/fprintf argument MUST match the associated format type char.

If the types don't match and it compiles, the results are very undefined.

Many newer compilers know about printf and issue warnings if the types do not match. If you get these warnings, FIX them.

If you want to convert types for arguments for variable functions, you must supply the cast (ie, explicit conversion) because the compiler can't figure out that a conversion needs to be performed (as it can with a function prototype with typed arguments).

printf("%d\n", (int) ch)

In this example, printf is being TOLD that there is an "int" on the stack. The cast makes sure that whatever thing sizeof returns (some sort of long integer, usually), printf will get an int.

printf("%d", (int) sizeof('\n'))

Only this one worked for me:

<script type="text/javascript">
var frames = document.getElementsByTagName("iframe");
    for (var i = 0; i < frames.length; i++) {
        src = frames[i].src;
        if (src.indexOf('embed') != -1) {
        if (src.indexOf('?') != -1) {
            frames[i].src += "&wmode=transparent";
        } else {
            frames[i].src += "?wmode=transparent";
        }
    }
}
</script>

I load it in the footer.php Wordpress file. Code found in comment here (thanks Gerson)

This Bootply example seems like a much better option. Only thing is that the labels are a little too high so I added padding-top:5px to center them with my inputs.

It seems that you have forgotten to add your state server address in the config file.

Did you recently updated your eclipse android plugin (adt r17)? Then the following link might help:

How to fix the classdefnotfounderror with adt-17

Update: One year has passed since the question arose. I will keep the link, because even in 2013 it seem to help some people to solve the problem. But please take care what you are doing, see Erics comment below. Current ADT-Version is 22, I recommend using the most current version.

public static Stream ToStream(this Image image)
{
     var stream = new MemoryStream();

     image.Save(stream, image.RawFormat);
     stream.Position = 0;

     return stream;
 }

I reached here for the problem Kudo mentioned.

I'm sharing my experience for others.

orElse, or orElseGet, that is the question:

static String B() {
    System.out.println("B()...");
    return "B";
}

public static void main(final String... args) {
    System.out.println(Optional.of("A").orElse(B()));
    System.out.println(Optional.of("A").orElseGet(() -> B()));
}

prints

B()...
A
A

orElse evaluates the value of B() interdependently of the value of the optional. Thus, orElseGet is lazy.

If you need generate numbers with intervals, it can be just like that:

Integer[] arr = new Integer[((int) (Math.random() * (16 - 30) + 30))];
for (int i = 0; i < arr.length; i++) {
arr[i] = i;
}
Collections.shuffle(Arrays.asList(arr));
System.out.println(Arrays.toString(arr));`

The result:

[1, 10, 2, 4, 9, 8, 7, 13, 18, 17, 5, 21, 12, 16, 23, 20, 6, 0, 22, 14, 24, 15, 3, 11, 19]

Note:

If you need that the zero does not leave you could put an "if"

Making the Frameworks in the Build Phases optional worked for me.

In Xcode -> Target -> Build Phases -> Link Binary with Libraries -> Make sure the newly added frameworks if any are marked as Optional

Your code can be fixed as follows:

import numpy as np, cv
vis = np.zeros((384, 836), np.float32)
h,w = vis.shape
vis2 = cv.CreateMat(h, w, cv.CV_32FC3)
vis0 = cv.fromarray(vis)
cv.CvtColor(vis0, vis2, cv.CV_GRAY2BGR)

Short explanation:

1. np.uint32 data type is not supported by OpenCV (it supports uint8, int8, uint16, int16, int32, float32, float64)
2. cv.CvtColor can't handle numpy arrays so both arguments has to be converted to OpenCV type. cv.fromarray do this conversion.
3. Both arguments of cv.CvtColor must have the same depth. So I've changed source type to 32bit float to match the ddestination.

Also I recommend you use newer version of OpenCV python API because it uses numpy arrays as primary data type:

import numpy as np, cv2
vis = np.zeros((384, 836), np.float32)
vis2 = cv2.cvtColor(vis, cv2.COLOR_GRAY2BGR)

This might be interesting: From the documentation:

If you tried a merge which resulted in complex conflicts and want to start over, you can recover with git merge --abort.

But you could also do it the naive (but slow) way:

rm -Rf /tmp/repository
cp -r repository /tmp/
cd /tmp/repository
git merge ...
...if successful, do the real merge. :)

(Note: It won't work just cloning to /tmp, you'd need a copy, in order to be sure that uncommitted changes will not conflict).

There are lots of sophisticated regex testing and development tools, but if you just want a simple test harness in Java, here's one for you to play with:

    String[] tests = {
        "AAA123",
        "ABCDEFGH123",
        "XXXX123",
        "XYZ123ABC",
        "123123",
        "X123",
        "123",
    };
    for (String test : tests) {
        System.out.println(test + " " +test.matches(".+123"));
    }

Now you can easily add new testcases and try new patterns. Have fun exploring regex.

I was also trying to join my path using path.join(__dirname, 'access.log') but it was throwing the same error.

Here is how I fixed it:

I first imported the path package and declared a variable named __dirname, then called the resolve path method.

In CommonJS

var path = require("path");

var __dirname = path.resolve();

In ES6+

import path  from 'path';

const __dirname = path.resolve();

Happy coding.......

You would be able to get at least temporary created copy of the file path on your machine. The only condition here is your input element should be within a form What you have to do else is putting in the form an attribute enctype, e.g.:

<form id="formid" enctype="multipart/form-data" method="post" action="{{url('/add_a_note' )}}">...</form>

you can find the path string at the bottom. It opens stream to file and then deletes it.

>>> () is ()
True
>>> 1 is 1
True
>>> (1,) == (1,)
True
>>> (1,) is (1,)
False
>>> a = (1,)
>>> b = a
>>> a is b
True

Some objects are singletons, and thus is with them is equivalent to ==. Most are not.

Well, .html() uses .innerHTML which is faster than DOM creation.

There might be a problem with your DNS servers of the ISP. A computer by default uses the ISP's DNS servers. You can manually configure your DNS servers. It is free and usually better than your ISP.

1. Go to Control Panel ? Network and Internet ? Network and Sharing Centre
2. Click on Change Adapter settings.
3. Right click on your connection icon (Wireless Network Connection or Local Area Connection) and select properties.
4. Select Internet protocol version 4.
5. Click on "Use the following DNS server address" and type either of the two DNS given below.

Google Public DNS

Preferred DNS server : 8.8.8.8
Alternate DNS server : 8.8.4.4

OpenDNS

Preferred DNS server : 208.67.222.222
Alternate DNS server : 208.67.220.220

$('#checkbox').prop('checked', true);

When you want it unchecked:

$('#checkbox').prop('checked', false);

This is a matplotlib question, and you can get around this by using a backend that doesn't display to the user, e.g. 'Agg':

import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt

plt.plot([1,2,3])
plt.savefig('/tmp/test.png')

EDIT: If you don't want to lose the ability to display plots, turn off Interactive Mode, and only call plt.show() when you are ready to display the plots:

import matplotlib.pyplot as plt

# Turn interactive plotting off
plt.ioff()

# Create a new figure, plot into it, then close it so it never gets displayed
fig = plt.figure()
plt.plot([1,2,3])
plt.savefig('/tmp/test0.png')
plt.close(fig)

# Create a new figure, plot into it, then don't close it so it does get displayed
plt.figure()
plt.plot([1,3,2])
plt.savefig('/tmp/test1.png')

# Display all "open" (non-closed) figures
plt.show()

'In' a string, you cant. Strings are immutable. You can easily create a second string with:

 String second = first.replaceFirst("(.)(.)", "$2$1");

I doing something to similar to wize but in my answer yo can change between the two fragments whenever you want. And with the wize answer I have some problems when changing the orientation of the screen an things like that. This is the PagerAdapter looks like:

    public class MyAdapter extends FragmentPagerAdapter
{
    static final int NUM_ITEMS = 2;
    private final FragmentManager mFragmentManager;
    private Fragment mFragmentAtPos0;
     private Map<Integer, String> mFragmentTags;
     private boolean isNextFragment=false;

    public MyAdapter(FragmentManager fm)
    {
        super(fm);
        mFragmentManager = fm;
         mFragmentTags = new HashMap<Integer, String>();
    }

    @Override
    public Fragment getItem(int position)
    {
        if (position == 0)
        {


            if (isPager) {
                mFragmentAtPos0 = new FirstPageFragment();
            } else {
                mFragmentAtPos0 = new NextFragment();
            }
            return mFragmentAtPos0;
        }
        else
            return SecondPageFragment.newInstance();
    }

    @Override
    public int getCount()
    {
        return NUM_ITEMS;
    }


 @Override
    public Object instantiateItem(ViewGroup container, int position) {
        Object obj = super.instantiateItem(container, position);
        if (obj instanceof Fragment) {
            // record the fragment tag here.
            Fragment f = (Fragment) obj;
            String tag = f.getTag();
            mFragmentTags.put(position, tag);
        }
        return obj;
    }


    public void onChange(boolean isNextFragment) {

        if (mFragmentAtPos0 == null)
            mFragmentAtPos0 = getFragment(0);
        if (mFragmentAtPos0 != null)
            mFragmentManager.beginTransaction().remove(mFragmentAtPos0).commit();


        if (!isNextFragment) {
            mFragmentAtFlashcards = new FirstPageFragment();
        } else {
            mFragmentAtFlashcards = new NextFragment();
        }

        notifyDataSetChanged();


    }


    @Override
    public int getItemPosition(Object object)
    {
        if (object instanceof FirstPageFragment && mFragmentAtPos0 instanceof NextFragment)
            return POSITION_NONE;
         if (object instanceof NextFragment && mFragmentAtPos0 instanceof FirstPageFragment)
            return POSITION_NONE;
        return POSITION_UNCHANGED;
    }


    public Fragment getFragment(int position) {
        String tag = mFragmentTags.get(position);
        if (tag == null)
            return null;
        return mFragmentManager.findFragmentByTag(tag);
    }
}

The listener I implemented in the adapter container activity to put it to the fragment when attaching it, this is the activity:

    public class PagerContainerActivity extends AppCompatActivity implements ChangeFragmentListener {

//...

  @Override
    public void onChange(boolean isNextFragment) {
        if (pagerAdapter != null)
            pagerAdapter.onChange(isNextFragment);


    }

//...
}

Then in the fragment putting the listener when attach an calling it:

public class FirstPageFragment extends Fragment{


private ChangeFragmentListener changeFragmentListener;


//...
 @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);
        changeFragmentListener = ((PagerContainerActivity) activity);
    }

    @Override
    public void onDetach() {
        super.onDetach();
        changeFragmentListener = null;
    }
//...
//in the on click to change the fragment
changeFragmentListener.onChange(true);
//...
}

And finally the listener:

public interface changeFragmentListener {

    void onChange(boolean isNextFragment);

}

This is from PasswordEncoder interface documentation from Spring Security,

 * @param rawPassword the raw password to encode and match
 * @param encodedPassword the encoded password from storage to compare with
 * @return true if the raw password, after encoding, matches the encoded password from
 * storage
 */
boolean matches(CharSequence rawPassword, String encodedPassword);

Which means, one will need to match rawPassword that user will enter again upon next login and matches it with Bcrypt encoded password that's stores in database during previous login/registration.

OAuth v2 specs indicates:

Access token attributes and the methods used to access protected resources are beyond the scope of this specification and are defined by companion specifications.

My Authorisation Server has a webservice (SOAP) endpoint that allows the Resource Server to know whether the access_token is valid.

boto3 also has a method for uploading a file directly:

s3 = boto3.resource('s3')    
s3.Bucket('bucketname').upload_file('/local/file/here.txt','folder/sub/path/to/s3key')

http://boto3.readthedocs.io/en/latest/reference/services/s3.html#S3.Bucket.upload_file

What worked for me was adding a div around the content. Originally i had this. Css applied to the td had no effect.

        <td>           
             @Html.DisplayFor(modelItem => item.Message)           
        </td>

Then I wrapped the content in a div and the css worked as expected

       <td>
            <div class="largeContent">
                @Html.DisplayFor(modelItem => item.Message)
            </div>
        </td>

This is a simple method to export the database to a folder named backup folder you can name it as you want and a simple method to import the database from the same folder a

    public class ExportImportDB extends Activity {

            // TODO Auto-generated method stub
            super.onCreate(savedInstanceState);
//creating a new folder for the database to be backuped to
            File direct = new File(Environment.getExternalStorageDirectory() + "/Exam Creator");

               if(!direct.exists())
                {

No, enums are supposed to be a complete static enumeration.

At compile time, you might want to generate your enum .java file from another source file of some sort. You could even create a .class file like this.

In some cases you might want a set of standard values but allow extension. The usual way to do this is have an interface for the interface and an enum that implements that interface for the standard values. Of course, you lose the ability to switch when you only have a reference to the interface.

Here's the nearly shortest possible solution to your question. The solution works in python 3.x. For python 2.x change the import to Tkinter rather than tkinter (the difference being the capitalization):

import tkinter as tk
#import Tkinter as tk  # for python 2
    
def create_window():
    window = tk.Toplevel(root)

root = tk.Tk()
b = tk.Button(root, text="Create new window", command=create_window)
b.pack()

root.mainloop()

This is definitely not what I recommend as an example of good coding style, but it illustrates the basic concepts: a button with a command, and a function that creates a window.

TextView does not support setMargins. Android docs say:

Even though a view can define a padding, it does not provide any support for margins. However, view groups provide such a support. Refer to ViewGroup and ViewGroup.MarginLayoutParams for further information.

The only thing that stops you from using urlopen directly on a file object is the fact that the builtin file object lacks a len definition. A simple way is to create a subclass, which provides urlopen with the correct file. I have also modified the Content-Type header in the file below.

import os
import urllib2
class EnhancedFile(file):
    def __init__(self, *args, **keyws):
        file.__init__(self, *args, **keyws)

    def __len__(self):
        return int(os.fstat(self.fileno())[6])

theFile = EnhancedFile('a.xml', 'r')
theUrl = "http://example.com/abcde"
theHeaders= {'Content-Type': 'text/xml'}

theRequest = urllib2.Request(theUrl, theFile, theHeaders)

response = urllib2.urlopen(theRequest)

theFile.close()


for line in response:
    print line

get the contact number whom you want to send the message and create uri for whatsapp, here c is a Cursor returning the selected contact.

Uri.parse("content://com.android.contacts/data/" + c.getString(0)));
i.setType("text/plain");
i.setPackage("com.whatsapp");           // so that only Whatsapp reacts and not the chooser
i.putExtra(Intent.EXTRA_SUBJECT, "Subject");
i.putExtra(Intent.EXTRA_TEXT, "I'm the body.");
startActivity(i);

This issue can also be caused if you include the normal jquery library twice. I had the following line twice, in my body and head.

It never caused any problems until I tried to use jquery UI as well.

This error can occur if two tables have a reference, for example, one table is Student and another table is Education, and we want the Education table to have a foreign key reference of Student table. In this instance the column data type for both tables should be same, otherwise it will generate an error.

There's also workaround doing disjunction of your array, worked for me as other solutions were hard to implement using some old framework.

select * from tableA where id = 1 or id = 2 or id = 3 ...

But for better perfo, I would use Nikolai Nechai's solution with unions, if possible.

The most common cause of this problem is that Matlab cannot find the file on it's search path. Basically, Matlab looks for files in:

1. The current directory (pwd);
2. Directly in a directory on the path (to see the path, type path at the command line)
3. In a directory named @(whatever the class of the first argument is) that is in any directory above.
   
   

   As someone else suggested, you can use the command which, but that is often unhelpful in this case - it tells you Matlab can't find the file, which you knew already.
   
   So the first thing to do is make sure the file is locatable on the path.
   

   Next thing to do is make sure that the file that matlab is finding (use which) requires the same type as the first argument you are actually passing. I.el, If w is supposed to be different class, and there is a divrat function there, but w is actually empty, [], so matlab is looking for Double/divrat, when there is only a @(yourclass)/divrat. This is just speculation on my part, but this often bites me.

You can just "call" your model with an array of the correct shape:

model(np.array([[6.7, 3.3, 5.7, 2.5]]))

Full example:

from sklearn.datasets import load_iris
from tensorflow.keras.layers import Dense
from tensorflow.keras.models import Sequential
import numpy as np

X, y = load_iris(return_X_y=True)

model = Sequential([
    Dense(16, activation='relu'),
    Dense(32, activation='relu'),
    Dense(1)])

model.compile(loss='mean_absolute_error', optimizer='adam')

history = model.fit(X, y, epochs=10, verbose=0)

print(model(np.array([[6.7, 3.3, 5.7, 2.5]])))

<tf.Tensor: shape=(1, 1), dtype=float64, numpy=array([[1.92517677]])>

In SQL Server you can use YEAR, MONTH and DAY instead of DATEPART.
(at least in SQL Server 2005/2008, I'm not sure about SQL Server 2000 and older)

I prefer using these "short forms" because to me, YEAR(getdate()) is shorter to type and better to read than DATEPART(yyyy, getdate()).

So you could also query your table like this:

select *
from your_table
where month_column = MONTH(getdate())
and year_column = YEAR(getdate())

CountRows = ThisWorkbook.Worksheets(1).Range("A:A").Cells.SpecialCells(xlCellTypeConstants).Count

if ( typeof query !== 'undefined' && query )
{
  //do stuff if query is defined and not null
}
else
{

}

You are missing a semicolon at the end of your 'struct' definition.

Also,

*sotrudnik

needs to be

sotrudnik*

try this. It will solve your problem.

 var lastDayOfMonth = DateTime.DaysInMonth(int.Parse(ddlyear.SelectedValue), int.Parse(ddlmonth.SelectedValue));
DateTime tLastDayMonth = Convert.ToDateTime(lastDayOfMonth.ToString() + "/" + ddlmonth.SelectedValue + "/" + ddlyear.SelectedValue);

You should find the 'expect' command will do what you need it to do. Its widely available. See here for an example : http://www.thegeekstuff.com/2010/10/expect-examples/

(very rough example)

#!/usr/bin/expect
set pass "mysecret"

spawn /usr/bin/passwd

expect "password: "
send "$pass"
expect "password: "
send "$pass"

I love JetBrains IDEs. For PHP it is JetBrains PHPStorm.

There is no way to do this in C. There are a lot of different approaches. Typically the simplest is to define a set of constants that represent your strings and do a look up by string on to get the constant:

#define BADKEY -1
#define A1 1
#define A2 2
#define B1 3
#define B2 4

typedef struct { char *key; int val; } t_symstruct;

static t_symstruct lookuptable[] = {
    { "A1", A1 }, { "A2", A2 }, { "B1", B1 }, { "B2", B2 }
};

#define NKEYS (sizeof(lookuptable)/sizeof(t_symstruct))

int keyfromstring(char *key)
{
    int i;
    for (i=0; i < NKEYS; i++) {
        t_symstruct *sym = lookuptable[i];
        if (strcmp(sym->key, key) == 0)
            return sym->val;
    }
    return BADKEY;
}

/* ... */
switch (keyfromstring(somestring)) {
case A1: /* ... */ break;
case A2: /* ... */ break;
case B1: /* ... */ break;
case B2: /* ... */ break;
case BADKEY: /* handle failed lookup */
}

There are, of course, more efficient ways to do this. If you keep your keys sorted, you can use a binary search. You could use a hashtable too. These things change your performance at the expense of maintenance.

If you are getting error like

Try removing the above file manually(Careful). Git will merge this file from master branch.

I'm in a particular situation where I do not have permissions to turn logging on, and wouldn't have permissions to see the logs if they were turned on. I could not add a trigger, but I did have permissions to call show processlist. So, I gave it a best effort and came up with this:

Create a bash script called "showsqlprocesslist":

#!/bin/bash

while [ 1 -le 1 ]
do
         mysql --port=**** --protocol=tcp --password=**** --user=**** --host=**** -e "show processlist\G" | grep Info | grep -v processlist | grep -v "Info: NULL";
done

Execute the script:

./showsqlprocesslist > showsqlprocesslist.out &

Tail the output:

tail -f showsqlprocesslist.out

Bingo bango. Even though it's not throttled, it only took up 2-4% CPU on the boxes I ran it on. I hope maybe this helps someone.

By omitting all parts of the head, the loop can also become infinite:

for (;;) {}

I hope you will find this useful.

$query1="SELECT TIMESTAMPDIFF (YEAR, YOUR_DOB_COLUMN, CURDATE()) AS age FROM your_table WHERE id='$user_id'";
$res1=mysql_query($query1);
$row=mysql_fetch_array($res1);
echo $row['age'];

If you want to create a small dots, just use icon from font awesome.

No both are different.

@Service annotation have use for other purpose and @Controller use for other. Actually Spring @Component, @Service, @Repository and @Controller annotations are used for automatic bean detection using classpath scan in Spring framework, but it doesn't ,mean that all functionalities are same. @Service: It indicates annotated class is a Service component in the business layer.

@Controller: Annotated class indicates that it is a controller components, and mainly used at presentation layer.

There is no support for array in sql server but there are several ways by which you can pass collection to a stored proc .

1. By using datatable
2. By using XML.Try converting your collection in an xml format and then pass it as an input to a stored procedure

The below link may help you

passing collection to a stored procedure

Your main() method is static, but it is referencing two non-static members: con2 and getConnectionUrl2(). You need to do one of three things:

1) Make con2 and getConnectionUrl2() static.

2) Inside main(), create an instance of class testconnect and access con2 and getConnectionUrl2() off of that.

3) Break out a different class to hold con2 and getConnectionUrl2() so that testconnect only has main in it. It will still need to instantiate the different class and call the methods off that.

Option #3 is the best option. #1 is the worst.

But, you cannot access non-static members from within a static method.

If you have already pushed the wrong name to remote, do the following:

1. Switch to the local branch you want to rename

   git checkout <old_name>

2. Rename the local branch

   git branch -m <new_name>

3. Push the <new_name> local branch and reset the upstream branch

   git push origin -u <new_name>

4. Delete the <old_name> remote branch

   git push origin --delete <old_name>

This was based on this article.

The maximum safe UDP payload is 508 bytes. This is a packet size of 576 (the "minimum maximum reassembly buffer size"), minus the maximum 60-byte IP header and the 8-byte UDP header.

Any UDP payload this size or smaller is guaranteed to be deliverable over IP (though not guaranteed to be delivered). Anything larger is allowed to be outright dropped by any router for any reason. Except on an IPv6-only route, where the maximum payload is 1,212 bytes. As others have mentioned, additional protocol headers could be added in some circumstances. A more conservative value of around 300-400 bytes may be preferred instead.

The maximum possible UDP payload is 67 KB, split into 45 IP packets, adding an additional 900 bytes of overhead (IPv4, MTU 1500, minimal 20-byte IP headers).

Any UDP packet may be fragmented. But this isn't too important, because losing a fragment has the same effect as losing an unfragmented packet: the entire packet is dropped. With UDP, this is going to happen either way.

^{_{IP packets include a fragment offset field, which indicates the byte offset of the UDP fragment in relation to its UDP packet. This field is 13-bit, allowing 8,192 values, which are in 8-byte units. So the range of such offsets an IP packet can refer to is 0...65,528 bytes. Being an offset, we add 1,480 for the last UDP fragment to get 67,008. Minus the UDP header in the first fragment gives us a nice, round 67 KB.}}

map[key] = value is provided for easier syntax. It is easier to read and write.

The reason for which you need to have default constructor is that map[key] is evaluated before assignment. If key wasn't present in map, new one is created (with default constructor) and reference to it is returned from operator[].

SOLUTIONS

1. Sometimes the project is created before installing g++. So install g++ first and then recreate your project. This worked for me.
2. Paste the following line in CMakeCache.txt: CMAKE_CXX_COMPILER:FILEPATH=/usr/bin/c++

Note the path to g++ depends on OS. I have used my fedora path obtained using which g++

If you need to change a file just once. You should prefer making the change locally and build a new docker image with this file.

Say in a docker image, you need to change a file named myFile.xml under /path/to/docker/image/. So, you need to do.

1. Copy myFile.xml in your local filesystem and make necessary changes.
2. Create a file named 'Dockerfile' with the following content-

FROM docker-repo:tag
ADD myFile.xml /path/to/docker/image/

Then build your own docker image with docker build -t docker-repo:v-x.x.x .

Then use your newly build docker image.

'<option value=''.$key.'">'

should be

'<option value="'.$key.'">'

Modern browsers (tested on Chrome, Firefox, Safari) implement some helper functions using the dollar sign $ that are very similar to jQuery (if the website doesn't define something using window.$).

Those utilities are quite useful for selecting elements in the DOM and modifying them.

You have several options

• Get map.values() , which gets the values, not the keys
• Get the map.entrySet() which has both
• Get the keySet() and for each key call map.get(key)

The geocoder has quota and rate limits. From experience, you can geocode ~10 locations without hitting the query limit (the actual number probably depends on server loading). The best solution is to delay when you get OVER_QUERY_LIMIT errors, then retry. See these similar posts:

• OVER_QUERY_LIMIT in Google Maps API v3: How do I pause/delay in Javascript to slow it down?

• How do I Geocode 20 addresses without receiving an OVER_QUERY_LIMIT response?

@($output).Count does not always produce correct results. I used the ($output | Measure).Count method.

I found this with VMware Get-VmQuestion cmdlet:

$output = Get-VmQuestion -VM vm1
@($output).Count

The answer it gave is one, whereas

$output

produced no output (the correct answer was 0 as produced with the Measure method).

This only seemed to be the case with 0 and 1. Anything above 1 was correct with limited testing.

UPDATE:

You have wrong capitalization of environment variables in ENV. Correct one is http_proxy. Your example should be:

FROM ubuntu:13.10
ENV http_proxy <HTTP_PROXY>
ENV https_proxy <HTTPS_PROXY>
RUN apt-get update && apt-get upgrade

or

FROM centos
ENV http_proxy <HTTP_PROXY>
ENV https_proxy <HTTPS_PROXY>
RUN yum update 

All variables specified in ENV are prepended to every RUN command. Every RUN command is executed in own container/environment, so it does not inherit variables from previous RUN commands!

Note: There is no need to call docker daemon with proxy for this to work, although if you want to pull images etc. you need to set the proxy for docker deamon too. You can set proxy for daemon in /etc/default/docker in Ubuntu (it does not affect containers setting).

Also, this can happen in case you run your proxy on host (i.e. localhost, 127.0.0.1). Localhost on host differ from localhost in container. In such case, you need to use another IP (like 172.17.42.1) to bind your proxy to or if you bind to 0.0.0.0, you can use 172.17.42.1 instead of 127.0.0.1 for connection from container during docker build.

You can also look for an example here: How to rebuild dockerfile quick by using cache?

Instead of setting async to false which is usually bad design, you may want to consider blocking the UI while the operation is pending.

This can be nicely achieved with jQuery promises as follows:

// same as $.ajax but settings can have a maskUI property
// if settings.maskUI==true, the UI will be blocked while ajax in progress
// if settings.maskUI is other than true, it's value will be used as the color value while bloking (i.e settings.maskUI='rgba(176,176,176,0.7)'
// in addition an hourglass is displayed while ajax in progress
function ajaxMaskUI(settings) {
    function maskPageOn(color) { // color can be ie. 'rgba(176,176,176,0.7)' or 'transparent'
        var div = $('#maskPageDiv');
        if (div.length === 0) {
            $(document.body).append('<div id="maskPageDiv" style="position:fixed;width:100%;height:100%;left:0;top:0;display:none"></div>'); // create it
            div = $('#maskPageDiv');
        }
        if (div.length !== 0) {
            div[0].style.zIndex = 2147483647;
            div[0].style.backgroundColor=color;
            div[0].style.display = 'inline';
        }
    }
    function maskPageOff() {
        var div = $('#maskPageDiv');
        if (div.length !== 0) {
            div[0].style.display = 'none';
            div[0].style.zIndex = 'auto';
        }
    }
    function hourglassOn() {
        if ($('style:contains("html.hourGlass")').length < 1) $('<style>').text('html.hourGlass, html.hourGlass * { cursor: wait !important; }').appendTo('head');
        $('html').addClass('hourGlass');
    }
    function hourglassOff() {
        $('html').removeClass('hourGlass');
    }

    if (settings.maskUI===true) settings.maskUI='transparent';

    if (!!settings.maskUI) {
        maskPageOn(settings.maskUI);
        hourglassOn();
    }

    var dfd = new $.Deferred();
    $.ajax(settings)
        .fail(function(jqXHR, textStatus, errorThrown) {
            if (!!settings.maskUI) {
                maskPageOff();
                hourglassOff();
            }
            dfd.reject(jqXHR, textStatus, errorThrown);
        }).done(function(data, textStatus, jqXHR) {
            if (!!settings.maskUI) {
                maskPageOff();
                hourglassOff();
            }
            dfd.resolve(data, textStatus, jqXHR);
        });

    return dfd.promise();
}

with this you can now do:

ajaxMaskUI({
    url: url,
    maskUI: true // or try for example 'rgba(176,176,176,0.7)'
}).fail(function (jqXHR, textStatus, errorThrown) {
    console.log('error ' + textStatus);
}).done(function (data, textStatus, jqXHR) {
    console.log('success ' + JSON.stringify(data));
});

And the UI will block until the ajax command returns

see jsfiddle

var user = [
  { id: 1, name: 'Siddhu' },
  { id: 2, name: 'Siddhartha' },
  { id: 3, name: 'Tiwary' }
];

var recToRemove={ id: 1, name: 'Siddhu' };

user.splice(user.indexOf(recToRemove),1)

i dont think that we can use where clause in insert statement

If you only need the standard functionality of hide only with visibility:hidden to keep the current layout you can use the callback function of hide to alter the css in the tag. Hide docs in jquery

An example :

$('#subs_selection_box').fadeOut('slow', function() {
      $(this).css({"visibility":"hidden"});
      $(this).css({"display":"block"});
});

This will use the normal cool animation to hide the div, but after the animation finish you set the visibility to hidden and display to block.

An example : http://jsfiddle.net/bTkKG/1/

I know you didnt want the $("#aa").css() solution, but you did not specify if it was because using only the css() method you lose the animation.

In your XML for the image view, where you have android:background="@drawable/thumbs_down change this to android:src="@drawable/thumbs_down"

Currently it is placing that image as the background to the view and not the actual image in it.

For kotlin

fun unixToDate(timeStamp: Long) : String? {
    val time = java.util.Date(timeStamp as Long * 1000)
    val sdf = SimpleDateFormat("yyyy-MM-dd")
    return sdf.format(time)

}

-apple-system allows you to pick San Francisco in Safari. BlinkMacSystemFont is the corresponding alternative for Chrome.

It can be complicated to compute a diff in your head from the different sections in $MERGED and apply that. In my setup, meld helps by showing you these diffs visually, using:

[merge]
    tool = mymeld
    conflictstyle = diff3

[mergetool "mymeld"]
    cmd = meld --diff $BASE $REMOTE --diff $REMOTE $LOCAL --diff $LOCAL $MERGED

It looks strange but offers a very convenient work-flow, using three tabs:

1. in tab 1 you see (from left to right) the change that you should make in tab 2 to solve the merge conflict.

2. in the right side of tab 2 you apply the "change that you should make" and copy the entire file contents to the clipboard (using ctrl-a and ctrl-c).

3. in tab 3 replace the right side with the clipboard contents. If everything is correct, you will now see - from left to right - the same change as shown in tab 1 (but with different contexts). Save the changes made in this tab.

Notes:

• don't edit anything in tab 1
• don't save anything in tab 2 because that will produce annoying popups in tab 3

As mentioned in the comments to the question, the JDBC-ODBC Bridge is - as the name indicates - only a mechanism for the JDBC layer to "talk to" the ODBC layer. Even if you had a JDBC-ODBC Bridge on your Mac you would also need to have

• an implementation of ODBC itself, and
• an appropriate ODBC driver for the target database (ACE/Jet, a.k.a. "Access")

So, for most people, using JDBC-ODBC Bridge technology to manipulate ACE/Jet ("Access") databases is really a practical option only under Windows. It is also important to note that the JDBC-ODBC Bridge will be has been removed in Java 8 (ref: here).

There are other ways of manipulating ACE/Jet databases from Java, such as UCanAccess and Jackcess. Both of these are pure Java implementations so they work on non-Windows platforms. For details on how to use UCanAccess see

Manipulating an Access database from Java without ODBC

Jon really gave a nice solution, I didn't know you could do that!

At times what I resorted to was inheriting from the class and creating its constructors. E.g.

public class FooList : List<Foo> { ... }

Not the best solution (unless your assembly gets used by other people), but it works.

I think first one .To hide the complexity of Query. Its very appropriate for views .How when we normalize Database tables increases.Now to fetch data is very difficult when number of tables increases.So best way to handle is follow views.If i am wrong correct me.

From the documentation:

str.find(sub[, start[, end]])

Return the lowest index in the string where substring sub is found within the slice s[start:end]. Optional arguments start and end are interpreted as in slice notation. Return -1 if sub is not found.

So, some examples:

>>> my_str = 'abcdefioshgoihgs sijsiojs '
>>> my_str.find('a')
0
>>> my_str.find('g')
10
>>> my_str.find('s', 11)
15
>>> my_str.find('s', 15)
15
>>> my_str.find('s', 16)
17
>>> my_str.find('s', 11, 14)
-1

you can use: content:url("image.jpg")

<style>
.your-class-name{
    content: url("http://imgur.com/SZ8Cm.jpg");
}
</style>

<img class="your-class-name" src="..."/>

add a textbox and scrollbar

in VB

Private Sub Textbox1_ValueChanged(ByVal sender As System.Object, ByVal e As System.Windows.RoutedPropertyChangedEventArgs(Of System.Double)) Handles Textbox1.ValueChanged
     If e.OldValue > e.NewValue Then
         Textbox1.Text = (Textbox1.Text + 1)
     Else
         Textbox1.Text = (Textbox1.Text - 1)
     End If
End Sub

Attribute is a public variable inside the class/object. length attribute is a variable of int type.

The problem is that you are using a lower case v.

You need to set it to Value and it should fix your issue:

@Html.TextBoxFor(model => model.Destination, new { id = "txtPlace", Value= "3" })

I too like StaxMan would probably implement that QueryParam as a String, then handle the conversion, rethrowing as necessary.

If the locale specific behavior is the desired and expected behavior, you would use the following to return the 400 BAD REQUEST error:

throw new WebApplicationException(Response.Status.BAD_REQUEST);

See the JavaDoc for javax.ws.rs.core.Response.Status for more options.

If you are using Visual Studio 2017 or later which ships with MSBuild 15 or later, and your .csproj files are in the new PackageReference format, the simplest method is to use the new MSBuild Restore target.

No-one has actually answered the original question, which is "how do I get NuGet packages to auto-restore when building from the command-line with MSBuild?" The answer is: unless you are using the "Enable NuGet package restore" option (which is now deprecated as per this reference), you can't (but see below). If you are trying to do e.g. automated builds on a CI server, this sucks.

However there is a slightly roundabout way to get the desired behaviour:

1. Download the latest NuGet executable from https://dist.nuget.org/win-x86-commandline/latest/nuget.exe and place it somewhere in your PATH. (You can do this as a pre-build step.)
2. Run nuget restore which will auto-download all the missing packages.
3. Run msbuild to build your solution.

Aside: while the new and recommended way to do auto package restore involves less clutter in your version control, it also makes command-line package restore impossible unless you jump through the extra hoop of downloading and running nuget.exe. Progress?

For Windows 10 this is what I've found works for me:

1. Move your key to the Linux file system: mv ~/.ssh /home/{username}
2. Set the permission on that key: chmod 700 /home/{username}/.ssh/id_rsa
3. Create a symbolic link to the key: ln -s /home/{username}/.ssh ~/.ssh

This happens if you have set your home directory (~) to be stored in Windows instead of Linux (under /mnt/ vs /home/).

you can use FormData

take look at my snippet from MVC

var fd = new FormData();
fd.append("ProfilePicture", $("#mydropzone")[0].files[0]);// getting value from form feleds 
d.append("id", @(((User) Session["User"]).ID));// getting value from session

$.ajax({
    url: '@Url.Action("ChangeUserPicture", "User")',
    dataType: "json",
    data: fd,//here is your data
    processData: false,
    contentType: false,
    type: 'post',
    success: function(data) {},

With JDK, You can also use jinfo to connect to the JVM for the <PROCESS_ID> in question and get the value for MaxHeapSize:

jinfo -flag MaxHeapSize <PROCESS_ID>

This should work...

var displayDate = new Date().toLocaleDateString();

alert(displayDate);

But I suspect you are trying it on something else, for example:

var displayDate = Date.now.toLocaleDateString(); // No!

alert(displayDate);

A simple trick:

import java.util.Scanner;  

/* Add these codes at the end of your method ...*/

Scanner input = new Scanner(System.in);
System.out.print("Press Enter to quit...");
input.nextLine();

From the v3 documentation (Developer's Guide > Concepts > Developing for Mobile Devices):

Android and iOS devices respect the following <meta> tag:

<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />

This setting specifies that the map should be displayed full-screen and should not be resizable by the user. Note that the iPhone's Safari browser requires this <meta> tag be included within the page's <head> element.

You can use this example and change it's implementation like this:

[self enumerateAttribute:NSParagraphStyleAttributeName
                 inRange:NSMakeRange(0, self.length)
                 options:0
              usingBlock:^(id  _Nullable value, NSRange range, BOOL * _Nonnull stop) {
                  NSMutableParagraphStyle *paragraphStyle = [[NSParagraphStyle defaultParagraphStyle] mutableCopy];

                  //add your specific settings for paragraph
                  //...
                  //...

                  [self removeAttribute:NSParagraphStyleAttributeName range:range];
                  [self addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:range];
              }];

Can't test it right now, but:

select * from tablename where date >= dateadd(day, datediff(day, 1, getdate()), 0) and date < dateadd(day, datediff(day, 0, getdate()), 0)

how about just recasting inside a method that should invoke basically a automatic copy constructor

T t = new T();
T t2 = (T)t;  //eh something like that

        List<myclass> cloneum;
        public void SomeFuncB(ref List<myclass> _mylist)
        {
            cloneum = new List<myclass>();
            cloneum = (List < myclass >) _mylist;
            cloneum.Add(new myclass(3));
            _mylist = new List<myclass>();
        }

seems to work to me

You may run into such problem while dealing with scraped data stored as Pandas DataFrame.

This solution works like charm if the list of values is present as text.

def textToList(hashtags):
    return hashtags.strip('[]').replace('\'', '').replace(' ', '').split(',')

hashtags = "[ 'A','B','C' , ' D']"
hashtags = textToList(hashtags)

Output: ['A', 'B', 'C', 'D']

No external library required.

All answers are or to complicated, or need to set some variables on every request which is very wrong practice if we know the DRY concept. Here simple interceptor example, I set mouse on wait when ajax starts and set it to auto when ajax ends.

$httpProvider.interceptors.push(function($document) {
    return {
     'request': function(config) {
         // here ajax start
         // here we can for example add some class or show somethin
         $document.find("body").css("cursor","wait");

         return config;
      },

      'response': function(response) {
         // here ajax ends
         //here we should remove classes added on request start

         $document.find("body").css("cursor","auto");

         return response;
      }
    };
  });

Code has to be added in application config app.config. I showed how to change mouse on loading state but in there it is possible to show/hide any loader content, or add, remove some css classes which are showing the loader.

Interceptor will run on every ajax call, so no need to create special boolean variables ( $scope.loading=true/false etc. ) on every http call.

You are comparing two objects for equality. The snippet:

if (obj == this) {     return true; } 

is a quick test that can be read

"If the object I'm comparing myself to is me, return true"

. You usually see this happen in equals methods so they can exit early and avoid other costly comparisons.

First Collection is class Interface and you can not instantiate. Collection API

List Ver APi is also an interface class.

It may be so

List list = Collections.synchronizedList(new ArrayList(...)); 

ver enter link description here

Collection collection= Collections.synchronizedList(new ArrayList(...)); 

Very easy solution with jQuery:

$('#myFormId').attr('action', 'myNewActionTarget.html');

Your form:

<form action=get_action() id="myFormId">
...
</form>

With the new C++ standard (may need special flags to be enabled on your compiler) you can simply do:

std::vector<int> v { 34,23 };
// or
// std::vector<int> v = { 34,23 };

Or even:

std::vector<int> v(2);
v = { 34,23 };

On compilers that don't support this feature (initializer lists) yet you can emulate this with an array:

int vv[2] = { 12,43 };
std::vector<int> v(&vv[0], &vv[0]+2);

Or, for the case of assignment to an existing vector:

int vv[2] = { 12,43 };
v.assign(&vv[0], &vv[0]+2);

Like James Kanze suggested, it's more robust to have functions that give you the beginning and end of an array:

template <typename T, size_t N>
T* begin(T(&arr)[N]) { return &arr[0]; }
template <typename T, size_t N>
T* end(T(&arr)[N]) { return &arr[0]+N; }

And then you can do this without having to repeat the size all over:

int vv[] = { 12,43 };
std::vector<int> v(begin(vv), end(vv));
