I haven't managed to get WMDC working on Windows 10 (it hanged on splash screen upon start), so I've finally uninstalled it. But now I have a Portable Devices / Compact device in the Device Manager and I can browse my Windows Compact 7 device within Windows Explorer. All my apps using RAPI also work. Maybe this is the result of installing/uninstalling WMDC, or probably this functionality was already presented on Windows 10 and I've just overlooked it initially.

Since no-one else seems to have mentioned this, I had this problem on Windows 10 and fixed it:

• by ensuring that ANDROID_HOME was set in the system environments variables and then restarting Android Studio (you may have to log out and log in again / restart explorer.exe).
• possibly unrelated, but on Windows 10 ensure that the telnet client via Start -> 'features'

Firstly, on Unix you use mount, not ls /mnt: many things are not mounted in /mnt.

Anyhow, there's the mountvol DOS command, which continues to work in Powershell, and there's the Powershell-specific Get-PSDrive.

Device detection based on user-agent is not very good solution, better is to detect features like touch device (in new jQuery they remove $.browser and use $.support instead).

To detect mobile you can check for touch events:

function is_touch_device() {
  return 'ontouchstart' in window // works on most browsers 
      || 'onmsgesturechange' in window; // works on ie10
}

Taken from What's the best way to detect a 'touch screen' device using JavaScript?

Check for open loop devices mapped to a file on the filesystem with "losetup -a". They wont show up with either lsof or fuser.

I had Xamarin installed and tried to use Unity. Basically in any case you have to kill any application that might be talking to your device through ADB

Swift 5

/// Obtain the machine hardware platform from the `uname()` unix command
///
/// Example of return values
///  - `"iPhone8,1"` = iPhone 6s
///  - `"iPad6,7"` = iPad Pro (12.9-inch)
static var unameMachine: String {
    var utsnameInstance = utsname()
    uname(&utsnameInstance)
    let optionalString: String? = withUnsafePointer(to: &utsnameInstance.machine) {
        $0.withMemoryRebound(to: CChar.self, capacity: 1) {
            ptr in String.init(validatingUTF8: ptr)
        }
    }
    return optionalString ?? "N/A"
}

I had a similar issue, but with no source code to run on Xcode.

So if you want to test an application on a real device with a fake location you should use a VPN application.

There are plenty in the App Store to choose from - free ones without the option to choose a specific country/city and free ones which assign you a random location or asks you to choose from a limited set of default options.

also make sure adb isn't running in your processes automatically. If it's there right click open file location, figure out what is starting it, kill it with fire. Run the updated adb from an updated android sdk platform tools. This was the issue with mine, hope it helps someone.

there are two solution worked for me. 1) disconnect your device from the mac and reattach it. 2) disconnect your device from the mac and restart it and then connect it with mac it'll work

My device had disappeared from the adb devices list after connecting it to adb on another laptop.

I selected "Charge only" on the phone and then re-enabled USB debugging.

That resolved the problem for me.

To generate a certificate on the Apple provisioning profile website, firstly you have to generate keys on your mac, then upload the public key. Apple will generate your certificates with this key. When you download your certificates, tu be able to use them you need to have the private key.

The error "XCode could not find a valid private-key/certificate pair for this profile in your keychain." means you don't have the private key.

Maybe because your Mac was reinstalled, maybe because this key was generated on another Mac. So to be able to use your certificates, you need to find this key and install it on the keychain.

If you can not find it you can generate new keys restart this process on the provisioning profile website and get new certificates you will able to use.

1. Add a 'New Swift File'-> AppDelegateEx.swift

2. add an extension to AppDelegate

   import UIKit
   extension AppDelegate {
        class func isIPhone5 () -> Bool{
            return max(UIScreen.mainScreen().bounds.width, UIScreen.mainScreen().bounds.height) == 568.0
       }
       class func isIPhone6 () -> Bool {
           return max(UIScreen.mainScreen().bounds.width, UIScreen.mainScreen().bounds.height) == 667.0
       }
       class func isIPhone6Plus () -> Bool {
           return max(UIScreen.mainScreen().bounds.width, UIScreen.mainScreen().bounds.height) == 736.0
       }  
   }
   

3. usage:

       if AppDelegate.isIPhone5() {
           collectionViewTopConstraint.constant = 2
       }else if AppDelegate.isIPhone6() {
           collectionViewTopConstraint.constant = 20
       }
   

I've got this problem for long that I cant get my android emulator or device connect to the debugger while both the console and the emulator were displaying waiting for connecting to the debugger.

And configuration for debug inside eclipse also confused me so much before, but today, i got this problem solved, by the following steps:

When you want to debug a android project, for instance, mypro. you would right click on it in the "Package Explorer". Then choose "Debug as"-->"Android Application".

Then the emulator might stop at the "Waiting for connecting to debugger"(or something else similar to this).

Then you need to connect to the debugger yourself by click "DDMS" to open the DDMS perspective, and click "Devices" tab.

Then you can see a list of processes that are running on your emulator or device.

Double click on the one which you are debugging, then change to the Debug perspective, you can see the debugger is connected and you could debug your program. That's how I solved this problem.

By the way, my OS is Win7 32-bit. Eclipse's version is Helios Service Release 2. Android SDK is rev. 16 and platform-tools' 10.

Update.

I found that it is the problem of my TCP/IP configuration. The debugger can't be connected when i assign a static IP address(for access to internet).

So every time when the debugger is unable to connect, I always do the following steps:

1.close current eclipse window.

2.change the config of IP address to dynamic, it means getting a IP address by DHCP.

3.open up the eclipse again.

then the debugger is able to be connected. I thought it might be a issue of the internal mechanism of java debugger which is using socket connection.

Sometimes you need to reset ADB. To do that, in Eclipse, go:

Window>> Show View >> Android (Might be found in the "Other" option)>>Devices

in the device Tab, click the down arrow, and choose reset adb.

This is part of UIDevice as of iOS 3.2, e.g.:

[UIDevice currentDevice].userInterfaceIdiom == UIUserInterfaceIdiomPad

Referred link has correct answer, but there are written some libraries to make your work easy.

• https://github.com/yesidlazaro/GmailBackground
• https://github.com/thegenuinegourav/Android-Email-App-using-Javamail-Api
• https://github.com/prashantwosti/BackgroundMailLibrary

So don't write all code again, just use any of these library and get your work done in little time.

Sometimes you have to do something funky. Let's say you want to read from a command (the date example by SDGuero for example) but you want to avoid multiple forks.

read month day year << DATE_COMMAND
 $(date "+%m %d %Y")
DATE_COMMAND
echo $month $day $year

You could also pipe into the read command, but then you'd have to use the variables within a subshell:

day=n/a; month=n/a; year=n/a
date "+%d %m %Y" | { read day month year ; echo $day $month $year; }
echo $day $month $year

results in...

13 08 2013
n/a n/a n/a

Best way to use UserDefaults

Steps

1. Create extension of UserDefaults
2. Create enum with required Keys to store in local
3. Store and retrieve the local data wherever you want

Sample

extension UserDefaults{

    //MARK: Check Login
    func setLoggedIn(value: Bool) {
        set(value, forKey: UserDefaultsKeys.isLoggedIn.rawValue)
        //synchronize()
    }

    func isLoggedIn()-> Bool {
        return bool(forKey: UserDefaultsKeys.isLoggedIn.rawValue)
    }

    //MARK: Save User Data
    func setUserID(value: Int){
        set(value, forKey: UserDefaultsKeys.userID.rawValue)
        //synchronize()
    }

    //MARK: Retrieve User Data
    func getUserID() -> Int{
        return integer(forKey: UserDefaultsKeys.userID.rawValue)
    }
}

enum for Keys used to store data

enum UserDefaultsKeys : String {
    case isLoggedIn
    case userID
}

Save in UserDefaults where you want

UserDefaults.standard.setLoggedIn(value: true)          // String
UserDefaults.standard.setUserID(value: result.User.id!) // String

Retrieve data anywhere in app

print("ID : \(UserDefaults.standard.getUserID())")
UserDefaults.standard.getUserID()

Remove Values

UserDefaults.standard.removeObject(forKey: UserDefaultsKeys.userID) 

This way you can store primitive data in best

Update You need no use synchronize() to store the values. As @Moritz pointed out the it unnecessary and given the article about it.Check comments for more detail

Using your data:

test_data <- data.frame(
var0 = 100 + c(0, cumsum(runif(49, -20, 20))),
var1 = 150 + c(0, cumsum(runif(49, -10, 10))),
Dates = seq.Date(as.Date("2002-01-01"), by="1 month", length.out=100))

I create a stacked version which is what ggplot() would like to work with:

stacked <- with(test_data,
                data.frame(value = c(var0, var1),
                           variable = factor(rep(c("Var0","Var1"),
                                                 each = NROW(test_data))),
                           Dates = rep(Dates, 2)))

In this case producing stacked was quite easy as we only had to do a couple of manipulations, but reshape() and the reshape and reshape2 might be useful if you have a more complex real data set to manipulate.

Once the data are in this stacked form, it only requires a simple ggplot() call to produce the plot you wanted with all the extras (one reason why higher-level plotting packages like lattice and ggplot2 are so useful):

require(ggplot2)
p <- ggplot(stacked, aes(Dates, value, colour = variable))
p + geom_line()

I'll leave it to you to tidy up the axis labels, legend title etc.

HTH

This is what I normally use, albeit a bit manual:

/* Add a 'temporary' UDDT with the new definition */ 
exec sp_addtype t_myudt_tmp, 'numeric(18,5)', NULL 


/* Build a command to alter all the existing columns - cut and 
** paste the output, then run it */ 
select 'alter table dbo.' + TABLE_NAME + 
       ' alter column ' + COLUMN_NAME + ' t_myudt_tmp' 
from INFORMATION_SCHEMA.COLUMNS 
where DOMAIN_NAME = 't_myudt' 

/* Remove the old UDDT */ 
exec sp_droptype t_mydut


/* Rename the 'temporary' UDDT to the correct name */ 
exec sp_rename 't_myudt_tmp', 't_myudt', 'USERDATATYPE' 

In my case, i faced the problem while creating table from phpmyadmin. For id column i choose the primary option from index dropdown and filled the size 10.

If you're using phpmyadmin, to solve this problem change the index dropdown option again, after reselecting the primary option again it'll ask you the size, leave it blank and you're done.

         //Store the number of days after which you want to delete the logs.
         int Days = 30;

          // Storing the path of the directory where the logs are stored.
           String DirPath = System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().GetName().CodeBase).Substring(6) + "\\Log(s)\\";

          //Fetching all the folders.
            String[] objSubDirectory = Directory.GetDirectories(DirPath);

            //For each folder fetching all the files and matching with date given 
            foreach (String subdir in objSubDirectory)     
            {
                //Getting the path of the folder                 
                String strpath = Path.GetFullPath(subdir);
                //Fetching all the files from the folder.
                String[] strFiles = Directory.GetFiles(strpath);
                foreach (string files in strFiles)
                {
                    //For each file checking the creation date with the current date.
                    FileInfo objFile = new FileInfo(files);
                    if (objFile.CreationTime <= DateTime.Now.AddDays(-Days))
                    {
                        //Delete the file.
                        objFile.Delete();
                    }
                }

                //If folder contains no file then delete the folder also.
                if (Directory.GetFiles(strpath).Length == 0)
                {
                    DirectoryInfo objSubDir = new DirectoryInfo(subdir);
                    //Delete the folder.
                    objSubDir.Delete();
                }

            }

If the to-be-updated component is not inside the same NamingContainer component (ui:repeat, h:form, h:dataTable, etc), then you need to specify the "absolute" client ID. Prefix with : (the default NamingContainer separator character) to start from root.

<p:ajax process="@this" update="count :subTotal"/>

To be sure, check the client ID of the subTotal component in the generated HTML for the actual value. If it's inside for example a h:form as well, then it's prefixed with its client ID as well and you would need to fix it accordingly.

<p:ajax process="@this" update="count :formId:subTotal"/>

Space separation of IDs is more recommended as <f:ajax> doesn't support comma separation and starters would otherwise get confused.

Fastlane's sigh provides a fairly robust solution for resigning IPAs.

From their README:

Resign

If you generated your ipa file but want to apply a different code signing onto the ipa file, you can use sigh resign:

fastlane sigh resign

sigh will find the ipa file and the provisioning profile for you if they are located in the current folder.

You can pass more information using the command line:

fastlane sigh resign ./path/app.ipa --signing_identity "iPhone Distribution: Felix Krause" -p "my.mobileprovision"

It will even handle provisioning profiles for nested applications (eg. if you have watchkit apps)

The relational database uses a formal system of predicates to address data. The underlying physical implementation is of no substance and can vary to optimize for certain operations, but it must always assume the relational model. In layman's terms, that's just saying I know exactly how many values (attributes) each row (tuple) in my table (relation) has and now I want to exploit the fact accordingly, thoroughly and to it's extreme. That's the true nature of the beast. 

Since we're obviously the generation that has had a relational upbringing, if you look at NoSQL database models from the perspective of the relational model, again in layman's terms, the first obvious difference is that no assumptions about the number of values a row can contain is ever made. This is really oversimplifying the matter and does not cleanly apply to the intricacies of the physical models of every NoSQL database, but it's the pinnacle of the relational model and the first assumption we have to leave behind or, if you'd rather, the biggest leap we have to make.

We can agree to two things that are true for every DBMS: it can store any kind of data and has enough mathematical underpinnings to make it possible to manage the data in any way imaginable. The reality is that you'll never want to make the mistake of putting any of the two points to the test, but rather just stick with what the actual DBMS was really made for. In layman's terms: respect the beast within!

(Please note that I've avoided comparing the (obviously) well founded standards revolving around the relational model against the many flavors provided by NoSQL databases. If you'd like, consider NoSQL databases as an umbrella term for any DBMS that does not completely assume the relational model, in exclusion to everything else. The differences are too many, but that's the principal difference and the one I think would be of most use to you to understand the two.)

In Laravel 6 you can get it like this:

try {
    window.$ = window.jQuery = require('jquery');
} catch (e) {}

• For Xamarin.Android users

This could also be the result of not updating your support packages when targeting Android 7.1, 8.0+. Update them to v25.4.0.2+ and this particular error might go away(giving you´ve configured your file_path file correctly as others stated).

Giving context: I switched to targeting Oreo from Nougat in a Xamarin.Forms app and taking a picture with the Xam.Plugin.Media started failing with the above error message, so updating the packages did the trick for me ok.

I had a similiar problem. All I needed to do was type store.load(); in the delete handler. There was no need to subsequently type grid.getView().refresh();.

Instead of all this you can also type store.remove(record) in the delete handler; - this ensures that the deleted record no longer shows on the grid.

git checkout -f your_branch_name

git checkout -f your_branch_name

if you have troubles reverting changes:

git checkout .

if you want to remove untracked directories and files:

git clean -fd

This is different for each browser, in IE and windows you need to create what they call a pluggable protocol handler.

The basic steps are as follows:

1. Implement the IInternetProtocol interface.
2. Implement the IInternetProtocolRoot interface.
3. Implement the IClassFactory interface.
4. Optional. Implement the IInternetProtocolInfo interface. Support for the HTTP protocol is provided by the transaction handler.
5. If IInternetProtocolInfo is implemented, provide support for PARSE_SECURITY_URL and PARSE_SECURITY_DOMAIN so the URL security zone manager can handle the security properly. Write the code for your protocol handler.
6. Provide support for BINDF_NO_UI and BINDF_SILENTOPERATION.
7. Add a subkey for your protocol handler in the registry under HKEY_CLASSES_ROOT\PROTOCOLS\Handler.
8. Create a string value, CLSID, under the subkey and set the string to the CLSID of your protocol handler.

See About Asynchronous Pluggable Protocols on MSDN for more details on the windows side. There is also a sample in the windows SDK.

A quick google also showed this article on codeproject: http://www.codeproject.com/KB/IP/DataProtocol.aspx.

Finally, as a security guy I have to point out that this code needs to be battle hardened. It's at a high risk because to do it reliably you can't do it in managed code and have to do it in C++ (I suppose you could use VB6). You should consider whether you really need to do this and if you do, design it carefully and code it securely. An attacker can easily control the content that gets passed to you by simply including a link on a page. For example if you have a simple buffer overflow then nobody better do this: <a href="custom:foooo{insert long string for buffer overflow here}"> Click me for free porn</a>

Strongly consider using strsafe and the new secure CRT methods included in the VC8 and above compilers. See http://blogs.msdn.com/michael_howard/archive/2006/02/27/540123.aspx if you have no idea what I'm talking about.

The default MidpointRounding.ToEven, or Bankers' rounding (2.5 become 2, 4.5 becomes 4 and so on) has stung me before with writing reports for accounting, so I'll write a few words of what I found out, previously and from looking into it for this post.

Who are these bankers that are rounding down on even numbers (British bankers perhaps!)?

From wikipedia

The origin of the term bankers' rounding remains more obscure. If this rounding method was ever a standard in banking, the evidence has proved extremely difficult to find. To the contrary, section 2 of the European Commission report The Introduction of the Euro and the Rounding of Currency Amounts suggests that there had previously been no standard approach to rounding in banking; and it specifies that "half-way" amounts should be rounded up.

It seems a very strange way of rounding particularly for banking, unless of course banks use to receive lots of deposits of even amounts. Deposit £2.4m, but we'll call it £2m sir.

The IEEE Standard 754 dates back to 1985 and gives both ways of rounding, but with banker's as the recommended by the standard. This wikipedia article has a long list of how languages implement rounding (correct me if any of the below are wrong) and most don't use Bankers' but the rounding you're taught at school:

• C/C++ round() from math.h rounds away from zero (not banker's rounding)
• Java Math.Round rounds away from zero (it floors the result, adds 0.5, casts to an integer). There's an alternative in BigDecimal
• Perl uses a similar way to C
• Javascript is the same as Java's Math.Round.

In ionic 4.6 I use the following technique and it works. I am adding this answer so that if anybody is facing similar issues in newer ionic version app, it may help them.

i) Open app.module.ts and add the following code block to import HttpModule and HttpClientModule

import { HttpModule } from '@angular/http';
import {   HttpClientModule } from '@angular/common/http';

ii) In @NgModule import sections add below lines:

HttpModule,
HttpClientModule,

So, in my case @NgModule, looks like this:

@NgModule({
  declarations: [AppComponent ],
  entryComponents: [ ],
  imports: [
    BrowserModule,
    HttpModule,
    HttpClientModule,
    IonicModule.forRoot(),
    AppRoutingModule, 
  ],
  providers: [
    StatusBar,
    SplashScreen,
    { provide: RouteReuseStrategy, useClass: IonicRouteStrategy }
  ],
  bootstrap: [AppComponent]
})

That's it!

You can encode your string by using .encode()

Example:

'Hello World'.encode()

tl;dr: baz() { this.foo(); this.bar() }

In ES2015 this construct:

var obj = {
    foo() { console.log('foo') }
}

is equal to this ES5 code:

var obj = {
    foo : function foo() { console.log('foo') }
}

exports.default = {} is like creating an object, your default export translates to ES5 code like this:

exports['default'] = {
    foo: function foo() {
        console.log('foo');
    },
    bar: function bar() {
        console.log('bar');
    },
    baz: function baz() {
        foo();bar();
    }
};

now it's kind of obvious (I hope) that baz tries to call foo and bar defined somewhere in the outer scope, which are undefined. But this.foo and this.bar will resolve to the keys defined in exports['default'] object. So the default export referencing its own methods shold look like this:

export default {
    foo() { console.log('foo') }, 
    bar() { console.log('bar') },
    baz() { this.foo(); this.bar() }
}

See babel repl transpiled code.

If selection is not important, it is better to use an ItemsControl wrapped in a ScrollViewer. This combination is more light-weight than the Listbox (which actually is derived from ItemsControl already) and using it would eliminate the need to use a cheap hack to override behavior that is already absent from the ItemsControl.

In cases where the selection behavior IS actually important, then this obviously will not work. However, if you want to change the color of the Selected Item Background in such a way that it is not visible to the user, then that would only serve to confuse them. In cases where your intention is to change some other characteristic to indicate that the item is selected, then some of the other answers to this question may still be more relevant.

Here is a skeleton of how the markup should look:

    <ScrollViewer>
        <ItemsControl>
            <ItemsControl.ItemTemplate>
                <DataTemplate>
                    ...
                </DataTemplate>
            </ItemsControl.ItemTemplate>
        </ItemsControl>
    </ScrollViewer>

I don't know if this applies in this case, but sometimes the file got deleted for unknown reasons, copying it again into the respective folder should resolve the problem.

The quickest way would be with a pivot table. Make sure your column of data has a header row, highlight the data and the header, from the insert ribbon select pivot table and then drag your header from the pivot table fields list to the row labels and to the values boxes.

Here is a noise-free version of the solution which is to use with_items:

- name: add lines
  lineinfile: 
    dest: fruits.txt
    line: '{{ item }}'
  with_items:
    - 'Orange'
    - 'Apple'
    - 'Banana' 

For each item, if the item exists in fruits.txt no action is taken.

If the item does not exist it will be appended to the end of the file.

Easy-peasy.

As I don't see here similar approach, and I'm not enjoying setting h/m/s/ms to 0, as it can cause problems with accurate transition to local time zone with changed date object (I presume so), let me introduce here this, written few moments ago, lil function:

+: Easy to use, makes a basic comparison operations done (comparing day, month and year without time.)
-: It seems that this is a complete opposite of "out of the box" thinking.

function datecompare(date1, sign, date2) {
    var day1 = date1.getDate();
    var mon1 = date1.getMonth();
    var year1 = date1.getFullYear();
    var day2 = date2.getDate();
    var mon2 = date2.getMonth();
    var year2 = date2.getFullYear();
    if (sign === '===') {
        if (day1 === day2 && mon1 === mon2 && year1 === year2) return true;
        else return false;
    }
    else if (sign === '>') {
        if (year1 > year2) return true;
        else if (year1 === year2 && mon1 > mon2) return true;
        else if (year1 === year2 && mon1 === mon2 && day1 > day2) return true;
        else return false;
    }    
}

Usage:

datecompare(date1, '===', date2) for equality check,
datecompare(date1, '>', date2) for greater check,
!datecompare(date1, '>', date2) for less or equal check

Also, obviously, you can switch date1 and date2 in places to achieve any other simple comparison.

You can "abort" a task by running it on a thread you control and aborting that thread. This causes the task to complete in a faulted state with a ThreadAbortException. You can control thread creation with a custom task scheduler, as described in this answer. Note that the caveat about aborting a thread applies.

(If you don't ensure the task is created on its own thread, aborting it would abort either a thread-pool thread or the thread initiating the task, neither of which you typically want to do.)

Alright, this doesn't apply to the OP's exact situation, but for anyone like myself who comes here facing a similar issue, figure I should throw this out there-- maybe save a headache or two.

If you're using an non-standard "button" to ensure the submit event isn't called:

<form>
  <input type="hidden" name="hide" value="1">
  <a href="#" onclick="submitWithChecked(this.form)">Hide Selected</a>
 </form>

Then, when you try to access this.form in the script, it's going to come up undefined. As I discovered, apparently anchor elements don't have same access to a parent form element the way your standard form elements do.

In such cases, (again, assuming you are intentionally avoiding the submit event for the time-being), you can use a button with type="button"

<form>
  <input type="hidden" name="hide" value="1">
  <button type="button" onclick="submitWithChecked(this.form)">Hide Selected</a>
 </form>

(Addendum 2020: All these years later, I think the more important lesson to take away from this is to check your input. If my function had bothered to check that the argument it received was actually a form element, the problem would have been much easier to catch.)

Ok, I want to provide a small answer to one of the sub-questions that the OP asked that don't seem to be addressed in the existing questions. Caveat, I have not done any testing or code generation, or disassembly, just wanted to share a thought for others to possibly expound upon.

Why does the static change the performance?

The line in question: uint64_t size = atol(argv[1])<<20;

Short Answer

I would look at the assembly generated for accessing size and see if there are extra steps of pointer indirection involved for the non-static version.

Long Answer

Since there is only one copy of the variable whether it was declared static or not, and the size doesn't change, I theorize that the difference is the location of the memory used to back the variable along with where it is used in the code further down.

Ok, to start with the obvious, remember that all local variables (along with parameters) of a function are provided space on the stack for use as storage. Now, obviously, the stack frame for main() never cleans up and is only generated once. Ok, what about making it static? Well, in that case the compiler knows to reserve space in the global data space of the process so the location can not be cleared by the removal of a stack frame. But still, we only have one location so what is the difference? I suspect it has to do with how memory locations on the stack are referenced.

When the compiler is generating the symbol table, it just makes an entry for a label along with relevant attributes, like size, etc. It knows that it must reserve the appropriate space in memory but doesn't actually pick that location until somewhat later in process after doing liveness analysis and possibly register allocation. How then does the linker know what address to provide to the machine code for the final assembly code? It either knows the final location or knows how to arrive at the location. With a stack, it is pretty simple to refer to a location based one two elements, the pointer to the stackframe and then an offset into the frame. This is basically because the linker can't know the location of the stackframe before runtime.

Take a look at this video tutorial about Autolayout, they explain it carefully

The most important part is the concepts. Once you understand how the building blocks work, differences in syntax amount to little more than mild dialects. A layer on top of your regular expression engine's syntax is the syntax of the programming language you're using. Languages such as Perl remove most of this complication, but you'll have to keep in mind other considerations if you're using regular expressions in a C program.

If you think of regular expressions as building blocks that you can mix and match as you please, it helps you learn how to write and debug your own patterns but also how to understand patterns written by others.

Start simple

Conceptually, the simplest regular expressions are literal characters. The pattern N matches the character 'N'.

Regular expressions next to each other match sequences. For example, the pattern Nick matches the sequence 'N' followed by 'i' followed by 'c' followed by 'k'.

If you've ever used grep on Unix—even if only to search for ordinary looking strings—you've already been using regular expressions! (The re in grep refers to regular expressions.)

Order from the menu

Adding just a little complexity, you can match either 'Nick' or 'nick' with the pattern [Nn]ick. The part in square brackets is a character class, which means it matches exactly one of the enclosed characters. You can also use ranges in character classes, so [a-c] matches either 'a' or 'b' or 'c'.

The pattern . is special: rather than matching a literal dot only, it matches any character^†. It's the same conceptually as the really big character class [-.?+%$A-Za-z0-9...].

Think of character classes as menus: pick just one.

Helpful shortcuts

Using . can save you lots of typing, and there are other shortcuts for common patterns. Say you want to match a digit: one way to write that is [0-9]. Digits are a frequent match target, so you could instead use the shortcut \d. Others are \s (whitespace) and \w (word characters: alphanumerics or underscore).

The uppercased variants are their complements, so \S matches any non-whitespace character, for example.

Once is not enough

From there, you can repeat parts of your pattern with quantifiers. For example, the pattern ab?c matches 'abc' or 'ac' because the ? quantifier makes the subpattern it modifies optional. Other quantifiers are

• * (zero or more times)
• + (one or more times)
• {n} (exactly n times)
• {n,} (at least n times)
• {n,m} (at least n times but no more than m times)

Putting some of these blocks together, the pattern [Nn]*ick matches all of

• ick
• Nick
• nick
• Nnick
• nNick
• nnick
• (and so on)

The first match demonstrates an important lesson: * always succeeds! Any pattern can match zero times.

A few other useful examples:

• [0-9]+ (and its equivalent \d+) matches any non-negative integer
• \d{4}-\d{2}-\d{2} matches dates formatted like 2019-01-01

Grouping

A quantifier modifies the pattern to its immediate left. You might expect 0abc+0 to match '0abc0', '0abcabc0', and so forth, but the pattern immediately to the left of the plus quantifier is c. This means 0abc+0 matches '0abc0', '0abcc0', '0abccc0', and so on.

To match one or more sequences of 'abc' with zeros on the ends, use 0(abc)+0. The parentheses denote a subpattern that can be quantified as a unit. It's also common for regular expression engines to save or "capture" the portion of the input text that matches a parenthesized group. Extracting bits this way is much more flexible and less error-prone than counting indices and substr.

Alternation

Earlier, we saw one way to match either 'Nick' or 'nick'. Another is with alternation as in Nick|nick. Remember that alternation includes everything to its left and everything to its right. Use grouping parentheses to limit the scope of |, e.g., (Nick|nick).

For another example, you could equivalently write [a-c] as a|b|c, but this is likely to be suboptimal because many implementations assume alternatives will have lengths greater than 1.

Escaping

Although some characters match themselves, others have special meanings. The pattern \d+ doesn't match backslash followed by lowercase D followed by a plus sign: to get that, we'd use \\d\+. A backslash removes the special meaning from the following character.

Greediness

Regular expression quantifiers are greedy. This means they match as much text as they possibly can while allowing the entire pattern to match successfully.

For example, say the input is

"Hello," she said, "How are you?"

You might expect ".+" to match only 'Hello,' and will then be surprised when you see that it matched from 'Hello' all the way through 'you?'.

To switch from greedy to what you might think of as cautious, add an extra ? to the quantifier. Now you understand how \((.+?)\), the example from your question works. It matches the sequence of a literal left-parenthesis, followed by one or more characters, and terminated by a right-parenthesis.

If your input is '(123) (456)', then the first capture will be '123'. Non-greedy quantifiers want to allow the rest of the pattern to start matching as soon as possible.

(As to your confusion, I don't know of any regular-expression dialect where ((.+?)) would do the same thing. I suspect something got lost in transmission somewhere along the way.)

Anchors

Use the special pattern ^ to match only at the beginning of your input and $ to match only at the end. Making "bookends" with your patterns where you say, "I know what's at the front and back, but give me everything between" is a useful technique.

Say you want to match comments of the form

-- This is a comment --

you'd write ^--\s+(.+)\s+--$.

Build your own

Regular expressions are recursive, so now that you understand these basic rules, you can combine them however you like.

Footnote

†: The statement above that . matches any character is a simplification for pedagogical purposes that is not strictly true. Dot matches any character except newline, "\n", but in practice you rarely expect a pattern such as .+ to cross a newline boundary. Perl regexes have a /s switch and Java Pattern.DOTALL, for example, to make . match any character at all. For languages that don't have such a feature, you can use something like [\s\S] to match "any whitespace or any non-whitespace", in other words anything.

You can also change the default color cycle in your matplotlibrc file. If you don't know where that file is, do the following in python:

import matplotlib
matplotlib.matplotlib_fname()

This will show you the path to your currently used matplotlibrc file. In that file you will find amongst many other settings also the one for axes.color.cycle. Just put in your desired sequence of colors and you will find it in every plot you make. Note that you can also use all valid html color names in matplotlib.

A short summary:

sudo apt-get install python python-pip python3 python3-pip
sudo add-apt-repository ppa:jonathonf/python-3.6
sudo apt-get update
sudo apt-get install python3.6
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.5 1
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.6 2

Then

$ pip -V
pip 8.1.1 from /usr/lib/python2.7/dist-packages (python 2.7)
$ pip3 -V
pip 8.1.1 from /usr/local/lib/python3.5/dist-packages (python 3.5)

Then to select python 3.6 run

sudo update-alternatives --config python3

and select '2'. Then

$ pip3 -V
pip 8.1.1 from /usr/local/lib/python3.6/dist-packages (python 3.6)

To update pip select the desired version and

pip3 install --upgrade pip

$ pip3 -V
pip 9.0.1 from /usr/local/lib/python3.6/dist-packages (python 3.6)

Now your Bill date will show like.

You are using DictWriter.writerows() which expects a list of dicts, not a dict. You want DictWriter.writerow() to write a single row.

You will also want to use DictWriter.writeheader() if you want a header for you csv file.

You also might want to check out the with statement for opening files. It's not only more pythonic and readable but handles closing for you, even when exceptions occur.

Example with these changes made:

import csv

my_dict = {"test": 1, "testing": 2}

with open('mycsvfile.csv', 'w') as f:  # You will need 'wb' mode in Python 2.x
    w = csv.DictWriter(f, my_dict.keys())
    w.writeheader()
    w.writerow(my_dict)

Which produces:

test,testing
1,2

You can just type those in your shell

String encrypted = encryption.encryptOrNull("top secret string");
String decrypted = encryption.decryptOrNull(encrypted);

The fragment identifier (also known as: Fragment IDs, Anchor Identifiers, Named Anchors) introduced by a hash mark # is the optional last part of a URL for a document. It is typically used to identify a portion of that document.

<a href="http://www.someuri.com/page#fragment">Link to fragment identifier</a>

Syntax for URIs also allows an optional query part introduced by a question mark ?. In URIs with a query and a fragment the fragment follows the query.

<a href="http://www.someuri.com/page?query=1#fragment">Link to fragment with a query</a>

When a Web browser requests a resource from a Web server, the agent sends the URI to the server, but does not send the fragment. Instead, the agent waits for the server to send the resource, and then the agent (Web browser) processes the resource according to the document type and fragment value.

Named Anchors <a name="fragment"> are deprecated in XHTML 1.0, the ID attribute is the suggested replacement. <div id="fragment"></div>

There are several places where you can set environment variables.

• ~/.profile: use this for variables you want to set in all programs launched from the terminal (note that, unlike on Linux, all shells opened in Terminal.app are login shells).
• ~/.bashrc: this is invoked for shells which are not login shells. Use this for aliases and other things which need to be redefined in subshells, not for environment variables that are inherited.
• /etc/profile: this is loaded before ~/.profile, but is otherwise equivalent. Use it when you want the variable to apply to terminal programs launched by all users on the machine (assuming they use bash).
• ~/.MacOSX/environment.plist: this is read by loginwindow on login. It applies to all applications, including GUI ones, except those launched by Spotlight in 10.5 (not 10.6). It requires you to logout and login again for changes to take effect. This file is no longer supported as of OS X 10.8.
• your user's launchd instance: this applies to all programs launched by the user, GUI and CLI. You can apply changes at any time by using the setenv command in launchctl. In theory, you should be able to put setenv commands in ~/.launchd.conf, and launchd would read them automatically when the user logs in, but in practice support for this file was never implemented. Instead, you can use another mechanism to execute a script at login, and have that script call launchctl to set up the launchd environment.
• /etc/launchd.conf: this is read by launchd when the system starts up and when a user logs in. They affect every single process on the system, because launchd is the root process. To apply changes to the running root launchd you can pipe the commands into sudo launchctl.

The fundamental things to understand are:

• environment variables are inherited by a process's children at the time they are forked.
• the root process is a launchd instance, and there is also a separate launchd instance per user session.
• launchd allows you to change its current environment variables using launchctl; the updated variables are then inherited by all new processes it forks from then on.

Example of setting an environment variable with launchd:

echo setenv REPLACE_WITH_VAR REPLACE_WITH_VALUE | launchctl

Now, launch your GUI app that uses the variable, and voila!

To work around the fact that ~/.launchd.conf does not work, you can put the following script in ~/Library/LaunchAgents/local.launchd.conf.plist:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>Label</key>
  <string>local.launchd.conf</string>
  <key>ProgramArguments</key>
  <array>
    <string>sh</string>
    <string>-c</string>
    <string>launchctl &lt; ~/.launchd.conf</string>    
  </array>
  <key>RunAtLoad</key>
  <true/>
</dict>
</plist>

Then you can put setenv REPLACE_WITH_VAR REPLACE_WITH_VALUE inside ~/.launchd.conf, and it will be executed at each login.

Note that, when piping a command list into launchctl in this fashion, you will not be able to set environment variables with values containing spaces. If you need to do so, you can call launchctl as follows: launchctl setenv MYVARIABLE "QUOTE THE STRING".

Also, note that other programs that run at login may execute before the launchagent, and thus may not see the environment variables it sets.

            var fileSize = fileInput.get(0).files[0].size; // in bytes
            if(fileSize>maxSize){
                alert('file size is more then' + maxSize + ' bytes');
                return false;
            }else{
                alert('file size is correct- '+fileSize+' bytes');
            }
        }else{
            alert('choose file, please');
            return false;
        }

    });
});

This is an example of using REG_EXTENDED. This regular expression

"^(-)?([0-9]+)((,|.)([0-9]+))?\n$"

Allows you to catch decimal numbers in Spanish system and international. :)

        reti = regcomp(&regex, "^(-)?([0-9]+)((,|.)([0-9]+))?\n$", REG_EXTENDED);
        if (reti) {
            fprintf(stderr, "Could not compile regex\n");
            exit(1);
        }

        /* Execute regular expression */
        printf("%s\n", msgbuf);
        reti = regexec(&regex, msgbuf, 0, NULL, 0);
        if (!reti) {
            puts("Match");
        }
        else if (reti == REG_NOMATCH) {
            puts("No match");
        }
        else {
            regerror(reti, &regex, msgbuf, sizeof(msgbuf));
            fprintf(stderr, "Regex match failed: %s\n", msgbuf);
            exit(1);
        }

It's also possible to do something like this with ng-style:

I spent around 6 hours on the same issue today. Inserts go at a 'regular' speed (less than 3sec per 100K) up until to 5MI (out of total 30MI) rows and then the performance sinks drastically (all the way down to 1min per 100K).

I will not list all of the things that did not work and cut straight to the meat.

I dropped a primary key on the target table (which was a GUID) and my 30MI or rows happily flowed to their destination at a constant speed of less than 3sec per 100K.

UPDATE 9 July 2012 - Looks like this is fixed in RTM.

1. We already imply ^ and $ so you don't need to add them. (It doesn't appear to be a problem to include them, but you don't need them)
2. This appears to be a bug in ASP.NET MVC 4/Preview/Beta. I've opened a bug

View source shows the following:

data-val-regex-pattern="([a-zA-Z0-9 .&amp;&#39;-]+)"                  <-- MVC 3
data-val-regex-pattern="([a-zA-Z0-9&#32;.&amp;amp;&amp;#39;-]+)"      <-- MVC 4/Beta

It looks like we're double encoding.

You can set a layout manager like BorderLayout and then define more specifically, where your panel should go:

MainPanel mainPanel = new MainPanel();
JFrame mainFrame = new JFrame();
mainFrame.setLayout(new BorderLayout());
mainFrame.add(mainPanel, BorderLayout.CENTER);
mainFrame.pack();
mainFrame.setVisible(true);

This puts the panel into the center area of the frame and lets it grow automatically when resizing the frame.

Once should avoid emulating classical OO and use prototypical OO instead. A nice utility library for prototypical OO is traits.

Rather then overwriting methods and setting up inheritance chains (one should always favour object composition over object inheritance) you should be bundling re-usable functions into traits and creating objects with those.

Live Example

var modifyA = {
    modify: function() {
        this.x = 300;
        this.y = 400;
    }
};

var modifyB = {
    modify: function() {
        this.x = 3000;
        this.y = 4000;
    }
};

C = function(trait) {
    var o = Object.create(Object.prototype, Trait(trait));

    o.modify();
    console.log("sum : " + (o.x + o.y));

    return o;
}

//C(modifyA);
C(modifyB);

There's some sort of bogus character at the end of that source. Try deleting the last line and adding it back.

I can't figure out exactly what's there, yet ...

edit — I think it's a zero-width space, Unicode 200B. Seems pretty weird and I can't be sure of course that it's not a Stackoverflow artifact, but when I copy/paste that last function including the complete last line into the Chrome console, I get your error.

A notorious source of such characters are websites like jsfiddle. I'm not saying that there's anything wrong with them — it's just a side-effect of something, maybe the use of content-editable input widgets.

If you suspect you've got a case of this ailment, and you're on MacOS or Linux/Unix, the od command line tool can show you (albeit in a fairly ugly way) the numeric values in the characters of the source code file. Some IDEs and editors can show "funny" characters as well. Note that such characters aren't always a problem. It's perfectly OK (in most reasonable programming languages, anyway) for there to be embedded Unicode characters in string constants, for example. The problems start happening when the language parser encounters the characters when it doesn't expect them.

I am using JDK 7 for maven project and I used -Dhttps.protocols=TLSv1.2 as argument in JRE. It has allowed to download all maven repository which were failing earlier.

When you run php-cgi.exe from the dos command line, you will get the missing MSVCR110.dll pop up message.

Like Ben said, Get the x86 download for the dll here: http://www.microsoft.com/en-us/download/details.aspx?id=30679

As an alternative way you can use DriverManagerDataSource such as:

public DataSource getDataSource(DBInfo db) {

    DriverManagerDataSource dataSource = new DriverManagerDataSource();

    dataSource.setUsername(db.getUsername());
    dataSource.setPassword(db.getPassword());
    dataSource.setUrl(db.getUrl());
    dataSource.setDriverClassName(db.getDriverClassName());

    return dataSource;
}

However be careful about using it, because:

NOTE: This class is not an actual connection pool; it does not actually pool Connections. It just serves as simple replacement for a full-blown connection pool, implementing the same standard interface, but creating new Connections on every call. reference

String Interpolation

is a concept that languages like Perl have had for quite a while, and now we’ll get this ability in C# as well. In String Interpolation, we simply prefix the string with a $ (much like we use the @ for verbatim strings). Then, we simply surround the expressions we want to interpolate with curly braces (i.e. { and }):

It looks a lot like the String.Format() placeholders, but instead of an index, it is the expression itself inside the curly braces. In fact, it shouldn’t be a surprise that it looks like String.Format() because that’s really all it is – syntactical sugar that the compiler treats like String.Format() behind the scenes.

A great part is, the compiler now maintains the placeholders for you so you don’t have to worry about indexing the right argument because you simply place it right there in the string.

C# string interpolation is a method of concatenating,formatting and manipulating strings. This feature was introduced in C# 6.0. Using string interpolation, we can use objects and expressions as a part of the string interpolation operation.

Syntax of string interpolation starts with a ‘$’ symbol and expressions are defined within a bracket {} using the following syntax.

{<interpolatedExpression>[,<alignment>][:<formatString>]}  

Where:

• interpolatedExpression - The expression that produces a result to be formatted
• alignment - The constant expression whose value defines the minimum number of characters in the string representation of the result of the interpolated expression. If positive, the string representation is right-aligned; if negative, it's left-aligned.
• formatString - A format string that is supported by the type of the expression result.

The following code example concatenates a string where an object, author as a part of the string interpolation.

string author = "Mohit";  
string hello = $"Hello {author} !";  
Console.WriteLine(hello);  // Hello Mohit !

The CPU speed varies due to power saving. I originally noticed this because VMware gave me a helpful tip on my laptop, but this page mentions the same thing:

Quote from : VMWare tips and tricks Power saving (SpeedStep, C-states, P-States,...)

Your power saving settings may interfere significantly with vmware's performance. There are several levels of power saving.

CPU frequency

This should not lead to performance degradation, outside of having the obvious lower performance when running the CPU at a lower frequency (either manually of via governors like "ondemand" or "conservative"). The only problem with varying the CPU speed while vmware is running is that the Windows clock will gain of lose time. To prevent this, specify your full CPU speed in kHz in /etc/vmware/config

host.cpukHz = 2167000

This errors means that kubectl is attempting to connect to a Kubernetes apiserver running on your local machine, which is the default if you haven't configured it to talk to a remote apiserver.

SELECT * FROM my_table 
WHERE UPPER(some_field) != some_field

This should work with funny characters like åäöøüæï. You might need to use a language-specific utf-8 collation for the table.

Generally, there is a mistake in the HTTP verb used eg:

Calling PUT route with POST request

I recently encountered this problem while working on a contract project(deemed classified). The system in which I had to run the code did not have internet access, for security purposes of course, and so installing dependencies, using composer and npm, was becoming huge pain.

After much deliberation with my colleague, we decided to just wing it and copy paste our dependencies rather than doing composer install or npm install.

This led us to NOT add vendors and npm_modules in gitignore. This is when I encountered this problem.

Changed but not updated:
modified:   vendor/plugins/open_flash_chart_2 (modified content, untracked content)

I googled this a bit and found this helpful thread on SO. Not being too much of a pro in Git, and being a little intoxicated while working on it, I just searched for all the submodules in the vendors folder

find . -name ".git"

This gave me some 4-5 dependencies that had git on them. I removed all these .git folders and voila, it worked. I knows it's hack, and not a very geeky one anyways. O Gods of SO, please forgive me! Next time I promise to read up on gitlinks and obey O mighty Linus Tovalds.

[2017-07-25] since this continues to be the accepted answer, despite being a very hacky solution, I'm incorporating Gabi's code into it, leaving my own to serve as a bad example.

// my hacky approach:
function get_content() {
  var html = document.getElementById("txt").innerHTML;
  document.getElementById("txt").innerHTML = html.replace(/<[^>]*>/g, "");
}
// Gabi's elegant approach, but eliminating one unnecessary line of code:
function gabi_content() {
  var element = document.getElementById('txt');
  element.innerHTML = element.innerText || element.textContent;
}
// and exploiting the fact that IDs pollute the window namespace:
function txt_content() {
  txt.innerHTML = txt.innerText || txt.textContent;
}

.A {
  background: blue;
}

.B {
  font-style: italic;
}

.C {
  font-weight: bold;
}

<input type="button" onclick="get_content()" value="Get Content (bad)" />
<input type="button" onclick="gabi_content()" value="Get Content (good)" />
<input type="button" onclick="txt_content()" value="Get Content (shortest)" />
<p id='txt'>

I found a short comparison from MSDN

The .NET Framework Class Library includes four classes named Timer, each of which offers different functionality:

System.Timers.Timer, which fires an event and executes the code in one or more event sinks at regular intervals. The class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.

System.Threading.Timer, which executes a single callback method on a thread pool thread at regular intervals. The callback method is defined when the timer is instantiated and cannot be changed. Like the System.Timers.Timer class, this class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.

System.Windows.Forms.Timer, a Windows Forms component that fires an event and executes the code in one or more event sinks at regular intervals. The component has no user interface and is designed for use in a single-threaded environment.

System.Web.UI.Timer, an ASP.NET component that performs asynchronous or synchronous web page postbacks at a regular interval.

You should use .Load and not .LoadXML

MSDN Link

"The LoadXml method is for loading an XML string directly. You want to use the Load method instead."

Why not simply

var item = $('.field-item');
for (var i = 0; i <= item.length; i++) {
       if ($(item[i]).text() == 'someText') {
             $(item[i]).addClass('thisClass');
             //do some other stuff here
          }
     }

Even though this is an old post, I thought it would be helpful to mention an additional (partial and tangential) solution to this question on top of the very helpful workarounds that are already present in this thread.

At the time of writing (6 January 2021), GitHub has released a feature to upload .mp4 and .mov files up to 10 MB in size to issues, pull requests and discussion comments (as shared here). This is a direct embed, instead of "linking" it to external URLs as what we usually do. It is already out of public beta. You can attach files by dragging and dropping, selecting or pasting them. A preview of GitHub's new notice can be seen here:

Perhaps, in the future, we can slowly nudge GitHub to eventually extend this native feature to READMEs as well.

I actually just wrote my own script for this purpose. It doesn't use Xcode. (It's based off a similar script in the Gambit Scheme project.)

Basically, it runs ./configure and make three times (for i386, armv7, and armv7s), and combines each of the resulting libraries into a fat lib.

According to the doc about Run tests by node ids

since you have all node ids in foo.txt, just run

pytest `cat foo.txt | tr '\n' ' '`

this is same with below command (with file content in the question)

pytest tests_directory/foo.py::test_001 tests_directory/bar.py::test_some_other_test

I had the exact same problem, found that I was missing

<mdb>  
  <resource-adapter-ref resource-adapter-name="hornetq-ra"/>  
  <bean-instance-pool-ref pool-name="mdb-strict-max-pool"/>

I take very seriously the concerns already voiced around creating a complete copy of your component state. With that said, I would strongly suggest Immer.

import produce from 'immer';

<Input
  value={this.state.form.username}
  onChange={e => produce(this.state, s => { s.form.username = e.target.value }) } />

This should work for React.PureComponent (i.e. shallow state comparisons by React) as Immer cleverly uses a proxy object to efficiently copy an arbitrarily deep state tree. Immer is also more typesafe compared to libraries like Immutability Helper, and is ideal for Javascript and Typescript users alike.

Typescript utility function

function setStateDeep<S>(comp: React.Component<any, S, any>, fn: (s: 
Draft<Readonly<S>>) => any) {
  comp.setState(produce(comp.state, s => { fn(s); }))
}

onChange={e => setStateDeep(this, s => s.form.username = e.target.value)}

The actual values are in radians but to interpret them in degrees it will be:

• atan = gives angle value between -90 and 90
• atan2 = gives angle value between -180 and 180

For my work which involves computation of various angles such as heading and bearing in navigation, atan2 in most cases does the job.

For rails 5.1+ callbacks

As of Ruby on Rails 5.1, the attribute_changed? and attribute_was ActiveRecord methods will be deprecated

Use saved_change_to_attribute? instead of attribute_changed?

@user.saved_change_to_street1? # => true/false

I think, answers to this question are too old... currently some desktop and mobile browsers support HTML Templates for doing this.

I've built a little example:

Be careful using SqlDependency class - it has problems with memory leaks.

Just use a cross-platform, .NET 3.5, .NET Core compatible and open source solution - SqlDependencyEx. You can get notifications as well as data that was changed (you can access it through properties in notification event object). You can also tack DELETE\UPDATE\INSERT operations separately or together.

Here is an example of how easy it is to use SqlDependencyEx:

int changesReceived = 0;
using (SqlDependencyEx sqlDependency = new SqlDependencyEx(
          TEST_CONNECTION_STRING, TEST_DATABASE_NAME, TEST_TABLE_NAME)) 
{
    sqlDependency.TableChanged += (o, e) => changesReceived++;
    sqlDependency.Start();

    // Make table changes.
    MakeTableInsertDeleteChanges(changesCount);

    // Wait a little bit to receive all changes.
    Thread.Sleep(1000);
}

Assert.AreEqual(changesCount, changesReceived);

Please follow the links for details. This component was tested in many enterprise-level applications and proven to be reliable. Hope this helps.

I'm following the spec here and I'm not sure whether it allows onFulfilled to be called with multiple arguments.

Nope, just the first parameter will be treated as resolution value in the promise constructor. You can resolve with a composite value like an object or array.

I don't care about how any specific promises implementation does it, I wish to follow the w3c spec for promises closely.

That's where I believe you're wrong. The specification is designed to be minimal and is built for interoperating between promise libraries. The idea is to have a subset which DOM futures for example can reliably use and libraries can consume. Promise implementations do what you ask with .spread for a while now. For example:

Promise.try(function(){
    return ["Hello","World","!"];
}).spread(function(a,b,c){
    console.log(a,b+c); // "Hello World!";
});

With Bluebird. One solution if you want this functionality is to polyfill it.

if (!Promise.prototype.spread) {
    Promise.prototype.spread = function (fn) {
        return this.then(function (args) {
            return Promise.all(args); // wait for all
        }).then(function(args){
         //this is always undefined in A+ complaint, but just in case
            return fn.apply(this, args); 
        });
    };
}

This lets you do:

Promise.resolve(null).then(function(){
    return ["Hello","World","!"]; 
}).spread(function(a,b,c){
    console.log(a,b+c);    
});

With native promises at ease fiddle. Or use spread which is now (2018) commonplace in browsers:

Promise.resolve(["Hello","World","!"]).then(([a,b,c]) => {
  console.log(a,b+c);    
});

Or with await:

let [a, b, c] = await Promise.resolve(['hello', 'world', '!']);

I think the usual use case is to call it when no exception was thrown in a negative test.

Something like the following pseudo-code:

test_addNilThrowsNullPointerException()
{
    try {
        foo.add(NIL);                      // we expect a NullPointerException here
        fail("No NullPointerException");   // cause the test to fail if we reach this            
     } catch (NullNullPointerException e) {
        // OK got the expected exception
    }
}

Roll your own e.g.

function syncJSON(i_url, callback) {
  $.ajax({
    type: "POST",
    async: false,
    url: i_url,
    contentType: "application/json",
    dataType: "json",
    success: function (msg) { callback(msg) },
    error: function (msg) { alert('error : ' + msg.d); }
  });
}

syncJSON("/pathToYourResouce", function (msg) {
   console.log(msg);
})

For those using ReactJS.Net and getting this error after a publish:

Check the properties of your .jsx files and make sure Build Action is set to Content. Those set to None will not be published. I came upon this solution from this SO answer.

Step1: Delete all instances of java from you machine

Step2: Delete all the environment variables related to java/jdk/jre

Step3: Check in programm files and program files(X86) folder, there should not be java folder.

Step4: Install java again.

Step5: Go to cmd and type "java -version" Result: it will display the java version which is installed in your machine.

Step6: now delete all the files which are in C:/User/AdminOrUserNameofYourMachine/.m2 folder

Step6: go to cmd and run "mvn -v" Result: It will display the Apache maven version installed on your machine

Step7: Now Rebuild your project.

This worked for me.

PowerShell features a Restart-Service cmdlet, which either starts or restarts the service as appropriate.

The Restart-Service cmdlet sends a stop message and then a start message to the Windows Service Controller for a specified service. If a service was already stopped, it is started without notifying you of an error.

You can specify the services by their service names or display names, or you can use the InputObject parameter to pass an object that represents each service that you want to restart.

It is a little more foolproof than running two separate commands.

The easiest way to use it just pass either the service name or the display name directly:

Restart-Service 'Service Name'

It can be used directly from the standard cmd prompt with a command like:

powershell -command "Restart-Service 'Service Name'"

Many users suggested that you use

echo json_encode($results, JSON_PRETTY_PRINT);

Which is absolutely right. But it's not enough, the browser needs to understand the type of data, you can specify the header just before echo-ing the data back to the user.

header('Content-Type: application/json');

This will result in a well formatted output.

Or, if you like extensions you can use JSONView for Chrome.

Just looking at the message it sounds like one or more of the components that you reference, or one or more of their dependencies is not registered properly.

If you know which component it is you can use regsvr32.exe to register it, just open a command prompt, go to the directory where the component is and type regsvr32 filename.dll (assuming it's a dll), if it works, try to run the code again otherwise come back here with the error.

If you don't know which component it is, try re-installing/repairing the GIS software (I assume you've installed some GIS software that includes the component you're trying to use).

curl doesn't have an option to that (without also specifying the filename), but wget does. The directory can be relative or absolute. Also, the directory will automatically be created if it doesn't exist.

wget -P relative/dir "$url"

wget -P /absolute/dir "$url"

You can also follow the "official" way. Run "sdkmanager --licenses" within tools/bin folder of Android SDK installation and accept all licenses. Done!

c:\android-sdk\tools\bin>sdkmanager --licenses

For macOS or Linux it's the same command.

checked the program and the results are as,

p++;    // use it then move to next int position
++p;    // move to next int and then use it
++*p;   // increments the value by 1 then use it 
++(*p); // increments the value by 1 then use it
++*(p); // increments the value by 1 then use it
*p++;   // use the value of p then moves to next position
(*p)++; // use the value of p then increment the value
*(p)++; // use the value of p then moves to next position
*++p;   // moves to the next int location then use that value
*(++p); // moves to next location then use that value

The solution is already answered here above (long ago).

But the implicit question "why does it work in FF and IE but not in Chrome and Safari" is found in the error text "Not allowed to load local resource": Chrome and Safari seem to use a more strict implementation of sandboxing (for security reasons) than the other two (at this time 2011).

This applies for local access. In a (normal) server environment (apache ...) the file would simply not have been found.

== has higher precedence than &. You might want to wrap your operations in () to specify how you want your operands to bind to the operators.

((a[0] & 1) == 0)

If no From: header is specified in the e-mail headers, the MTA uses the full name of the current user, in this case "Apache". You can edit full user names in /etc/passwd

On Windows:

You can create a shortcut executing

Anaconda3\pythonw.exe Anaconda3\cwp.py Anaconda3\envs\<your_env> Anaconda3\envs\<your env>\pythonw.exe Anaconda3\envs\<your_env>\Scripts\spyder-script.py

However, if you started spyder from your venv inside Anaconda shell, it creates this shortcut for you automatically in the Windows menu. The steps:

1. install spyder in your venv using the methods mentioned in the other answers here.

2. (in anaconda:) activate testenv

3. Look up the windows menu "recently added" or just search for "spyder" in the windows menu, find spyder (testenv) and

• [add that to taskbar] and / or

• [look up the file source location] and copy that to your desktop, e.g. from C:\Users\USER\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Anaconda3 (64-bit), where the spyder links for any of my environments can be found.

Now you can directly start spyder from a shortcut without the need to open anaconda prompt.

Perl provides the ref() function so that you can check the reference type before dereferencing a reference...

By using the ref() function you can protect program code that dereferences variables from producing errors when the wrong type of reference is used...

or try to install a pre-release version by enabling the --pre option:

pip install pygame --pre

When the result is success but you get the "<" character, it means that some PHP error is returned.

If you want to see all message, you could get the result as a success response getting by the following:

success: function(response){
     var out = "";
     for(var i = 0; i < response.length; i++) {
        out += response[i];
     }
     alert(out) ;
},

These are macros that give hints to the compiler about which way a branch may go. The macros expand to GCC specific extensions, if they're available.

GCC uses these to to optimize for branch prediction. For example, if you have something like the following

if (unlikely(x)) {
  dosomething();
}

return x;

Then it can restructure this code to be something more like:

if (!x) {
  return x;
}

dosomething();
return x;

The benefit of this is that when the processor takes a branch the first time, there is significant overhead, because it may have been speculatively loading and executing code further ahead. When it determines it will take the branch, then it has to invalidate that, and start at the branch target.

Most modern processors now have some sort of branch prediction, but that only assists when you've been through the branch before, and the branch is still in the branch prediction cache.

There are a number of other strategies that the compiler and processor can use in these scenarios. You can find more details on how branch predictors work at Wikipedia: http://en.wikipedia.org/wiki/Branch_predictor

Just put the full directory location in the File object.

File file = new File("z:\\results.txt");

Use which(mydata_2$height_chad1 == 2585)

Short example

df <- data.frame(x = c(1,1,2,3,4,5,6,3),
                 y = c(5,4,6,7,8,3,2,4))
df
  x y
1 1 5
2 1 4
3 2 6
4 3 7
5 4 8
6 5 3
7 6 2
8 3 4

which(df$x == 3)
[1] 4 8

length(which(df$x == 3))
[1] 2

count(df, vars = "x")
  x freq
1 1    2
2 2    1
3 3    2
4 4    1
5 5    1
6 6    1

df[which(df$x == 3),]
  x y
4 3 7
8 3 4

As Matt Weller pointed out, you can use the length function. The count function in plyr can be used to return the count of each unique column value.

The difference is that you can lock and unlock a std::unique_lock. std::lock_guard will be locked only once on construction and unlocked on destruction.

So for use case B you definitely need a std::unique_lock for the condition variable. In case A it depends whether you need to relock the guard.

std::unique_lock has other features that allow it to e.g.: be constructed without locking the mutex immediately but to build the RAII wrapper (see here).

std::lock_guard also provides a convenient RAII wrapper, but cannot lock multiple mutexes safely. It can be used when you need a wrapper for a limited scope, e.g.: a member function:

class MyClass{
    std::mutex my_mutex;
    void member_foo() {
        std::lock_guard<mutex_type> lock(this->my_mutex);            
        /*
         block of code which needs mutual exclusion (e.g. open the same 
         file in multiple threads).
        */

        //mutex is automatically released when lock goes out of scope
    }           
};

To clarify a question by chmike, by default std::lock_guard and std::unique_lock are the same. So in the above case, you could replace std::lock_guard with std::unique_lock. However, std::unique_lock might have a tad more overhead.

Note that these days (since, C++17) one should use std::scoped_lock instead of std::lock_guard.

As rightly said in above answers, by calling flush() we force hibernate to execute the SQL commands on Database. But do understand that changes are not "committed" yet. So after doing flush and before doing commit, if you access DB directly (say from SQL prompt) and check the modified rows, you will NOT see the changes.

This is same as opening 2 SQL command sessions. And changes done in 1 session are not visible to others until committed.

Swift 4, Xcode 9

I like Pheepster's answer, but how about we do it all from the extension, without requiring VC code or any subclassing:

import UIKit

@IBDesignable
extension UITextField {

    @IBInspectable var paddingLeftCustom: CGFloat {
        get {
            return leftView!.frame.size.width
        }
        set {
            let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: newValue, height: frame.size.height))
            leftView = paddingView
            leftViewMode = .always
        }
    }

    @IBInspectable var paddingRightCustom: CGFloat {
        get {
            return rightView!.frame.size.width
        }
        set {
            let paddingView = UIView(frame: CGRect(x: 0, y: 0, width: newValue, height: frame.size.height))
            rightView = paddingView
            rightViewMode = .always     
        }
    }
}

You can receive returning results like that: AsyncTask class

@Override
protected Boolean doInBackground(Void... params) {
    if (host.isEmpty() || dbName.isEmpty() || user.isEmpty() || pass.isEmpty() || port.isEmpty()) {
        try {
            throw new SQLException("Database credentials missing");
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }

    try {
        Class.forName("org.postgresql.Driver");
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }

    try {
        this.conn = DriverManager.getConnection(this.host + ':' + this.port + '/' + this.dbName, this.user, this.pass);
    } catch (SQLException e) {
        e.printStackTrace();
    }

    return true;
}

receiving class:

_store.execute();
boolean result =_store.get();

Hoping it will help.

The following example in JavaScript/Jquery will do that-

<telerik:RadScriptBlock ID="RadScriptBlock1" runat="server">
<script type="text/javascript">
     function count(text, event) {

         var keyCode = event.keyCode;

         //THIS IS FOR CONTROL KEY
         var ctrlDown = event.ctrlKey;

         var maxlength = $("#<%=txtMEDaiSSOWebAddress1.ClientID%>").val().length;

         if (maxlength < 200) {
             event.returnValue = true;
         }
         else {

             if ((keyCode == 8) || (keyCode == 9) || (keyCode == 46) || (keyCode == 33) || (keyCode == 27) || (keyCode == 145) || (keyCode == 19) || (keyCode == 34) || (keyCode == 37) || (keyCode == 39) || (keyCode == 16) || (keyCode == 18) ||
                 (keyCode == 38) || (keyCode == 40) || (keyCode == 35) || (keyCode == 36) || (ctrlDown && keyCode == 88) || (ctrlDown && keyCode == 65) || (ctrlDown && keyCode == 67) || (ctrlDown && keyCode == 86)) 

                  {
                 event.returnValue = true;
                  }

             else {

                 event.returnValue = false;
             }
         }

     }

     function substr(text)
      {
          var txtWebAdd = $("#<%=txtMEDaiSSOWebAddress1.ClientID%>").val();
          var substrWebAdd;
          if (txtWebAdd.length > 200) 
          {                 
              substrWebAdd = txtWebAdd.substring(0, 200);                                  
              $("#<%=txtMEDaiSSOWebAddress1.ClientID%>").val('');
              $("#<%=txtMEDaiSSOWebAddress1.ClientID%>").val(substrWebAdd); 

          }
     }                  

I think that it really depends on your personal coding style. If you're used to C++, Javascript, etc., you might feel more comfortable using the {} syntax. If you're used to Visual Basic, you might want to use the if : endif; syntax.

I'm not sure one can definitively say one is easier to read than the other - it's personal preference. I usually do something like this:

<?php
if ($foo) { ?>
   <p>Foo!</p><?php
} else { ?>
   <p>Bar!</p><?php
}  // if-else ($foo) ?>

Whether that's easier to read than:

<?php
if ($foo): ?>
   <p>Foo!</p><?php
else: ?>
   <p>Bar!</p><?php
endif; ?>

is a matter of opinion. I can see why some would feel the 2nd way is easier - but only if you haven't been programming in Javascript and C++ all your life. :)

How to import a commons-library into netbeans.

1. Evaluate the error message in NetBeans:

   java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
   

2. NoClassDeffFoundError means somewhere under the hood in the code you used, a method called another method which invoked a class that cannot be found. So what that means is your code did this: MyFoobarClass foobar = new MyFoobarClass() and the compiler is confused because nowhere is defined this MyFoobarClass. This is why you get an error.

3. To know what to do next, you have to look at the error message closely. The words 'org/apache/commons' lets you know that this is the codebase that provides the tools you need. You have a choice, either you can import EVERYTHING in apache commons, or you could import JUST the LogFactory class, or you could do something in between. Like for example just get the logging bit of apache commons.

4. You'll want to go the middle of the road and get commons-logging. Excellent choice, fire up the google and search for apache commons-logging. The first link takes you to http://commons.apache.org/proper/commons-logging/. Go to downloads. There you will find the most up-to-date ones. If your project was compiled under ancient versions of commons-logging, then use those same ancient ones because if you use the newer ones, the code may fail because the newer versions are different.

5. You're going to want to download the commons-logging-1.1.3-bin.zip or something to that effect. Read what the name is saying. The .zip means it's a compressed file. commons-logging means that this one should contain the LogFactory class you desire. the middle 1.1.3 means that is the version. if you are compiling for an old version, you'll need to match these up, or else you risk the code not compiling right due to changes due to upgrading.

6. Download that zip. Unzip it. Search around for things that end in .jar. In netbeans right click your project, click properties, click libraries, click "add jar/folder" and import those jars. Save the project, and re-run, and the errors should be gone.

The binaries don't include the source code, so you won't be able to drill down and see what is happening when you debug. As programmers you should be downloading "the source" of apache commons and compiling from source, generating the jars yourself and importing those for experience. You should be smart enough to understand and correct the source code you are importing. These ancient versions of apache commons might have been compiled under an older version of Java, so if you go too far back, they may not even compile unless you compile them under an ancient version of java.

This post asks the same question, but for linux - you may find it helpful. Send a ping to each IP on a subnet

nmap is probably the best tool to use, as it can help identify host OS as well as being faster. It is available for the windows platform on the nmap.org site

Based on the answer by Thomas Watnedal. However, this does not answer the line-to-line part of the original question exactly. The function can still replace on a line-to-line basis

This implementation replaces the file contents without using temporary files, as a consequence file permissions remain unchanged.

Also re.sub instead of replace, allows regex replacement instead of plain text replacement only.

Reading the file as a single string instead of line by line allows for multiline match and replacement.

import re

def replace(file, pattern, subst):
    # Read contents from file as a single string
    file_handle = open(file, 'r')
    file_string = file_handle.read()
    file_handle.close()

    # Use RE package to allow for replacement (also allowing for (multiline) REGEX)
    file_string = (re.sub(pattern, subst, file_string))

    # Write contents to file.
    # Using mode 'w' truncates the file.
    file_handle = open(file, 'w')
    file_handle.write(file_string)
    file_handle.close()

As an alternate solution that may work in some cases: change the border-style to dotted.

Having alternating groups of pixels between the foreground color and the background color isn't the same as a continuous line of partially transparent pixels. On the other hand, this requires significantly less CSS and it is much more compatible across every browser without any browser-specific directives.

Add -lrt to the end of g++ command line. This links in the librt.so "Real Time" shared library.

It can be done without using the sys library if we look at the print() function

print(*objects, sep=' ', end='\n', file=sys.stdout, flush=False)

Here is my code:

def update(n):
    for i in range(n):
        print("i:",i,sep='',end="\r",flush=True)
        #time.sleep(1)

You can do it like this:

In your main view controller:

func showModal() {
    let modalViewController = ModalViewController()
    modalViewController.modalPresentationStyle = .overCurrentContext
    presentViewController(modalViewController, animated: true, completion: nil)
}

In your modal view controller:

class ModalViewController: UIViewController {
    override func viewDidLoad() {
        view.backgroundColor = UIColor.clearColor()
        view.opaque = false
    }
}

If you are working with a storyboard:

Just add a Storyboard Segue with Kind set to Present Modally to your modal view controller and on this view controller set the following values:

• Background = Clear Color
• Drawing = Uncheck the Opaque checkbox
• Presentation = Over Current Context

As Crashalot pointed out in his comment: Make sure the segue only uses Default for both Presentation and Transition. Using Current Context for Presentation makes the modal turn black instead of remaining transparent.

to serve static files (css,images,js files)just two steps:

1. pass the directory of css files to built in middleware express.static

   var express = require('express');
   var app = express();
   /*public is folder in my project directory contains three folders
   css,image,js
   */
   //css  =>folder contains css file
   //image=>folder contains images
   //js   =>folder contains javascript files
   app.use(express.static( 'public/css'));
   

2. to access css files or images just type in url http://localhost:port/filename.css ex:http://localhost:8081/bootstrap.css

note: to link css files to html just type<link href="file_name.css" rel="stylesheet">

if i write this code

var express = require('express');
var app = express();
app.use('/css',express.static( 'public/css'));

to access the static files just type in url:localhost:port/css/filename.css ex:http://localhost:8081/css/bootstrap.css

note to link css files with html just add the following line

<link href="css/file_name.css" rel="stylesheet">    

This is usually caused by a program that writes into the event log and is then uninstalled or moved.

Recently I found a better solution.

If your text contains every letter in uppercase, then TextInfo will not convert it to the proper case. We can fix that by using the lowercase function inside like this:

public static string ConvertTo_ProperCase(string text)
{
    TextInfo myTI = new CultureInfo("en-US", false).TextInfo;
    return myTI.ToTitleCase(text.ToLower());
}

Now this will convert everything that comes in to Propercase.

If you want to scroll the element you're over and prevent the window to scroll, here's a really useful function :

$('.Scrollable').on('DOMMouseScroll mousewheel', function(ev) {
    var $this = $(this),
        scrollTop = this.scrollTop,
        scrollHeight = this.scrollHeight,
        height = $this.height(),
        delta = (ev.type == 'DOMMouseScroll' ?
            ev.originalEvent.detail * -40 :
            ev.originalEvent.wheelDelta),
        up = delta > 0;

    var prevent = function() {
        ev.stopPropagation();
        ev.preventDefault();
        ev.returnValue = false;
        return false;
    }

    if (!up && -delta > scrollHeight - height - scrollTop) {
        // Scrolling down, but this will take us past the bottom.
        $this.scrollTop(scrollHeight);

        return prevent();
    } else if (up && delta > scrollTop) {
        // Scrolling up, but this will take us past the top.
        $this.scrollTop(0);
        return prevent();
    }
});

Apply the class "Scrollable" to your element and that's it!

Summary:

Use is when you want to check against an object's identity (e.g. checking to see if var is None). Use == when you want to check equality (e.g. Is var equal to 3?).

Explanation:

You can have custom classes where my_var == None will return True

e.g:

class Negator(object):
    def __eq__(self,other):
        return not other

thing = Negator()
print thing == None    #True
print thing is None    #False

is checks for object identity. There is only 1 object None, so when you do my_var is None, you're checking whether they actually are the same object (not just equivalent objects)

In other words, == is a check for equivalence (which is defined from object to object) whereas is checks for object identity:

lst = [1,2,3]
lst == lst[:]  # This is True since the lists are "equivalent"
lst is lst[:]  # This is False since they're actually different objects

A web app can request access to a sandboxed file system by calling window.requestFileSystem(). Works in Chrome.

window.requestFileSystem = window.requestFileSystem || window.webkitRequestFileSystem;
var fs = null;

window.requestFileSystem(window.TEMPORARY, 1024 * 1024, function (filesystem) {
    fs = filesystem;
}, errorHandler);

fs.root.getFile('Hello.txt', {
    create: true
}, null, errorHandler);

function errorHandler(e) {
  var msg = '';

  switch (e.code) {
    case FileError.QUOTA_EXCEEDED_ERR:
      msg = 'QUOTA_EXCEEDED_ERR';
      break;
    case FileError.NOT_FOUND_ERR:
      msg = 'NOT_FOUND_ERR';
      break;
    case FileError.SECURITY_ERR:
      msg = 'SECURITY_ERR';
      break;
    case FileError.INVALID_MODIFICATION_ERR:
      msg = 'INVALID_MODIFICATION_ERR';
      break;
    case FileError.INVALID_STATE_ERR:
      msg = 'INVALID_STATE_ERR';
      break;
    default:
      msg = 'Unknown Error';
      break;
  };

  console.log('Error: ' + msg);
}

More info here.

There are also these 'ways':

>>> dict.fromkeys(range(1, 4))
{1: None, 2: None, 3: None}
>>> dict(zip(range(1, 4), range(1, 4)))
{1: 1, 2: 2, 3: 3}

Have you tried git push? gitref.org has a nice section dealing with remote repositories.

You can also get help from the command line using the --help option. For example:

This article by Jan Wolter is the best piece I have came across, you can find the archived copy here if link is dead.

It explains all browser key events really well,

The keydown event occurs when the key is pressed, followed immediately by the keypress event. Then the keyup event is generated when the key is released.

To understand the difference between keydown and keypress, it is useful to distinguish between characters and keys. A key is a physical button on the computer's keyboard. A character is a symbol typed by pressing a button. On a US keyboard, hitting the 4 key while holding down the Shift key typically produces a "dollar sign" character. This is not necessarily the case on every keyboard in the world. In theory, the keydown and keyup events represent keys being pressed or released, while the keypress event represents a character being typed. In practice, this is not always the way it is implemented.

For a while, some browers fired an additional event, called textInput, immediately after keypress. Early versions of the DOM 3 standard intended this as a replacement for the keypress event, but the whole notion was later revoked. Webkit supported this between versions 525 and 533, and I'm told IE supported it, but I never detected that, possibly because Webkit required it to be called textInput while IE called it textinput.

There is also an event called input, supported by all browsers, which is fired just after a change is made to to a textarea or input field. Typically keypress will fire, then the typed character will appear in the text area, then input will fire. The input event doesn't actually give any information about what key was typed - you'd have to inspect the textbox to figure it out what changed - so we don't really consider it a key event and don't really document it here. Though it was originally defined only for textareas and input boxes, I believe there is some movement toward generalizing it to fire on other types of objects as well.

I know that it will be inefficient but have you considered casting the text field to varchar so that you can use the solution provided by the website you found? I know that this solution would create issues as you could potentially truncate the record if the length in the text field overflowed the length of your varchar (not to mention it would not be very performant).

Since your data is inside a text field (and you are using SQL Server 2000) your options are limited.

You can use the following command to know just the name of the database without the extra columns shown.

select name  from v$database;

If you need any other information about the db then first know which are the columns names available using

describe v$database;

and select the columns that you want to see;

Take a look at this answer: ImportError: no module named win32api

You can use

pip install pypiwin32

1) Add the following line to /etc/security/limits.conf

webuser hard nofile 64000

then login as webuser

su - webuser

2) Edit following two files for webuser

append .bashrc and .bash_profile file by running

echo "ulimit -n 64000" >> .bashrc ; echo "ulimit -n 64000" >> .bash_profile

3) Log out, then log back in and verify that the changes have been made correctly:

$ ulimit -a | grep open
open files                      (-n) 64000

Thats it and them boom, boom boom.

(In Kotlin) If you are going to put the answer into a TextView or something you can instead use a string resource:

<string name="time">%02d:%02d</string>

And then you can use this String resource to then set the text at run time using:

private fun setTime(time: Int) {
    val hour = time / 60
    val min = time % 60
    main_time.text = getString(R.string.time, hour, min)
}

bash:

LD_LIBRARY_PATH=my_path
sqsub -np $1 /path/to/executable

Similar, in Python:

import os
import subprocess
import sys

os.environ['LD_LIBRARY_PATH'] = "my_path" # visible in this process + all children
subprocess.check_call(['sqsub', '-np', sys.argv[1], '/path/to/executable'],
                      env=dict(os.environ, SQSUB_VAR="visible in this subprocess"))

Probably, you need to insert schema identifier here:

in.addValue("po_system_users", null, OracleTypes.ARRAY, "your_schema.T_SYSTEM_USER_TAB");

If you are concerned with the comment by @Daap on the accepted answer and can only pass the value once, you could try one of the following

bool TestRangeDistance (int numberToCheck, int bottom, int distance)
{
  return (numberToCheck >= bottom && numberToCheck <= bottom+distance);
}

//var t = TestRangeDistance(10, somelist.Count()-5, 10);

or

bool TestRangeMargin (int numberToCheck, int target, int margin)
{
  return (numberToCheck >= target-margin && numberToCheck <= target+margin);
}

//var t = TestRangeMargin(10, somelist.Count(), 5);

My simple solution:

$("form").children('input[type="submit"]').click();

It is work for me.

If you have same columns in all your csv files then you can try the code below. I have added header=0 so that after reading csv first row can be assigned as the column names.

import pandas as pd
import glob

path = r'C:\DRO\DCL_rawdata_files' # use your path
all_files = glob.glob(path + "/*.csv")

li = []

for filename in all_files:
    df = pd.read_csv(filename, index_col=None, header=0)
    li.append(df)

frame = pd.concat(li, axis=0, ignore_index=True)

I recommend to use bellow formula suggested on Apache:

MaxClients = (total RAM - RAM for OS - RAM for external programs) / (RAM per httpd process)

Find my script here which is running on Rhel 6.7. you can made change according to your OS.

#!/bin/bash

@VonC's answer to a duplicate question:

If, as commented, Paraminko does not support PPK key, the official solution, as seen here, would be to use PuTTYgen.

But you can also use the Python library CkSshKey to make that same conversion directly in your program.

See "Convert PuTTY Private Key (ppk) to OpenSSH (pem)"

import sys
import chilkat

key = chilkat.CkSshKey()

#  Load an unencrypted or encrypted PuTTY private key.

#  If  your PuTTY private key is encrypted, set the Password
#  property before calling FromPuttyPrivateKey.
#  If your PuTTY private key is not encrypted, it makes no diffference
#  if Password is set or not set.
key.put_Password("secret")

#  First load the .ppk file into a string:

keyStr = key.loadText("putty_private_key.ppk")

#  Import into the SSH key object:
success = key.FromPuttyPrivateKey(keyStr)
if (success != True):
    print(key.lastErrorText())
    sys.exit()

#  Convert to an encrypted or unencrypted OpenSSH key.

#  First demonstrate converting to an unencrypted OpenSSH key

bEncrypt = False
unencryptedKeyStr = key.toOpenSshPrivateKey(bEncrypt)
success = key.SaveText(unencryptedKeyStr,"unencrypted_openssh.pem")
if (success != True):
    print(key.lastErrorText())
    sys.exit()

You can use JavaScript if you're familiar with, like that:

swfobject.embedSWF("filename.swf", "Title", "width", "height", "9.0.0");

--the 9.0.0 is the flash version.

Or you can use the <object> tag of HTML5.

Here is how we solved it

a Users table looked like this

Users
-------------------------------------------------
id | name | address | phone | email | created_on | updated_on

And the business requirement changed and we were in a need to check all previous addresses and phone numbers a user ever had. new schema looks like this

Users (the data that won't change over time)
-------------
id | name

UserData (the data that can change over time and needs to be tracked)
-------------------------------------------------
id | id_user | revision | city | address | phone | email | created_on
 1 |   1     |    0     | NY   | lake st | 9809  | @long | 2015-10-24 10:24:20
 2 |   1     |    2     | Tokyo| lake st | 9809  | @long | 2015-10-24 10:24:20
 3 |   1     |    3     | Sdny | lake st | 9809  | @long | 2015-10-24 10:24:20
 4 |   2     |    0     | Ankr | lake st | 9809  | @long | 2015-10-24 10:24:20
 5 |   2     |    1     | Lond | lake st | 9809  | @long | 2015-10-24 10:24:20

To find the current address of any user, we search for UserData with revision DESC and LIMIT 1

To get the address of a user between a certain period of time we can use created_on bewteen (date1 , date 2)

It is compile time error for a Static Library that is caused by Static Linker

ld: library not found for -l<Library_name>

1. You can get the error Library not found for when you have not include a library path to the Library Search Paths

ld means Static Linker which can not find a location of the library. As a developer you should help the linker and point the Library Search Paths

```
Build Settings -> Search Paths -> Library Search Paths 
```

2. Also you can get this error if you first time open a new project (.xcodeproj) with Cocoapods support, run pod update. To fix it just close this project and open created a workspace instead (.xcworkspace )

[Vocabulary]

Take a look at this question and this question for some good answers on C++ object instantiation.

This basic idea is that objects instantiated on the heap (using new) need to be cleaned up manually, those instantiated on the stack (without new) are automatically cleaned up when they go out of scope.

void SomeFunc()
{
    Point p1 = Point(0,0);
} // p1 is automatically freed

void SomeFunc2()
{
    Point *p1 = new Point(0,0);
    delete p1; // p1 is leaked unless it gets deleted
}

Note that if typing if ( exists $hash{ key } ) isn’t too much work for you (which I prefer to use since the matter of interest is really the presence of a key rather than the truthiness of its value), then you can use the short and sweet

@hash{@key} = ();

UNI: For UNIQUE:

• It is a set of one or more columns of a table to uniquely identify the record.
• A table can have multiple UNIQUE key.
• It is quite like primary key to allow unique values but can accept one null value which primary key does not.

PRI: For PRIMARY:

• It is also a set of one or more columns of a table to uniquely identify the record.
• A table can have only one PRIMARY key.
• It is quite like UNIQUE key to allow unique values but does not allow any null value.

MUL: For MULTIPLE:

• It is also a set of one or more columns of a table which does not identify the record uniquely.
• A table can have more than one MULTIPLE key.
• It can be created in table on index or foreign key adding, it does not allow null value.
• It allows duplicate entries in column.
• If we do not specify MUL column type then it is quite like a normal column but can allow null entries too hence; to restrict such entries we need to specify it.
• If we add indexes on column or add foreign key then automatically MUL key type added.

If you have the HTML

<form name="formname" .... id="form-first">
    <iframe id="one" src="iframe2.html">
    </iframe>
</form>

and JavaScript

function iframeRef( frameRef ) {
    return frameRef.contentWindow
        ? frameRef.contentWindow.document
        : frameRef.contentDocument
}

var inside = iframeRef( document.getElementById('one') )

inside is now a reference to the document, so you can do getElementsByTagName('textarea') and whatever you like, depending on what's inside the iframe src.

A smaller version (when compared to previous ones):

var customer = context.Find(id);
context.Delete(customer);
context.SaveChanges();

Simple and better solution : %WINDIR%\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe MyProject.sln I make a bat file like this %WINDIR%\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe D:\GESTION-SOMECOPA\GestionCommercial\GestionCommercial.sln pause

Then I can see all errors and correct them. Because when you change the folder name (without spaces as seen above) you will have another problems. Visual Studio 2015 works fine after this.

I use this and it is pretty handy:

git config --global alias.mkdir '!git checkout -b $1; git status; git push -u origin $1; exit;'

Usage: git mkdir NEW_BRANCH

You don't even need git status; maybe, I just want to make sure everything is going well...

You can have BOTH the LOCAL and REMOTE branch with a single command.

You can use this function in the route like this

app.get('/one/two', function (req, res) {
    const url = getFullUrl(req);
}

/**
 * Gets the self full URL from the request
 * 
 * @param {object} req Request
 * @returns {string} URL
 */
const getFullUrl = (req) => `${req.protocol}://${req.headers.host}${req.originalUrl}`;

req.protocol will give you http or https, req.headers.host will give you the full host name like www.google.com, req.originalUrl will give the rest pathName(in your case /one/two)

<?php

$string = 'foo';

if (preg_match('/[\'^£$%&*()}{@#~?><>,|=_+¬-]/', $string))
{
    // one or more of the 'special characters' found in $string
}

I like minimalism & simplicity.

Notice that this doesn't work in Windows.
The module pxssh does exactly what you want:
For example, to run 'ls -l' and to print the output, you need to do something like that :

from pexpect import pxssh
s = pxssh.pxssh()
if not s.login ('localhost', 'myusername', 'mypassword'):
    print "SSH session failed on login."
    print str(s)
else:
    print "SSH session login successful"
    s.sendline ('ls -l')
    s.prompt()         # match the prompt
    print s.before     # print everything before the prompt.
    s.logout()

Some links :

Pexpect (pxssh is based on pexpect) : http://pexpect.readthedocs.io/en/stable/

A deferred can be used in place of a mutex. This is essentially the same as the multiple ajax usage scenarios.

MUTEX

var mutex = 2;

setTimeout(function() {
 callback();
}, 800);

setTimeout(function() {
 callback();
}, 500);

function callback() {
 if (--mutex === 0) {
  //run code
 }
}

DEFERRED

function timeout(x) {
 var dfd = jQuery.Deferred();
 setTimeout(function() {
  dfd.resolve();
 }, x);
 return dfd.promise();
}

jQuery.when(
timeout(800), timeout(500)).done(function() {
 // run code
});

When using a Deferred as a mutex only, watch out for performance impacts (http://jsperf.com/deferred-vs-mutex/2). Though the convenience, as well as additional benefits supplied by a Deferred is well worth it, and in actual (user driven event based) usage the performance impact should not be noticeable.

For some reason I was not able to use my scalar function until I referenced it using brackets, like so:

select [dbo].[fun_functional_score]('01091400003')

You can simply cast strings to DateTime:

[DateTime]"2020-7-16"

or

[DateTime]"Jul-16"

or

$myDate = [DateTime]"Jul-16";

And you can format the resulting DateTime variable by doing something like this:

'{0:yyyy-MM-dd}' -f [DateTime]'Jul-16'

or

([DateTime]"Jul-16").ToString('yyyy-MM-dd')

or

$myDate = [DateTime]"Jul-16";
'{0:yyyy-MM-dd}' -f $myDate

You can use this:

@Html.DropDownListFor(x => x.Tipo, new List<SelectListItem>
    {
                        new SelectListItem() {Text = "Exemplo1", Value="Exemplo1"},
                        new SelectListItem() {Text = "Exemplo2", Value="Exemplo2"},
                        new SelectListItem() {Text = "Exemplo3", Value="Exemplo3"}
    })  

We can do with pandas

import pandas as pd
yourdict=pd.DataFrame(L).drop_duplicates().to_dict('r')
Out[293]: [{'age': 34, 'id': 1, 'name': 'john'}, {'age': 30, 'id': 2, 'name': 'hanna'}]

Notice slightly different from the accept answer.

drop_duplicates will check all column in pandas , if all same then the row will be dropped .

For example :

If we change the 2nd dict name from john to peter

L=[
    {'id': 1, 'name': 'john', 'age': 34},
    {'id': 1, 'name': 'peter', 'age': 34},
    {'id': 2, 'name': 'hanna', 'age': 30},
]
pd.DataFrame(L).drop_duplicates().to_dict('r')
Out[295]: 
[{'age': 34, 'id': 1, 'name': 'john'},
 {'age': 34, 'id': 1, 'name': 'peter'},# here will still keeping the dict in the out put 
 {'age': 30, 'id': 2, 'name': 'hanna'}]

git reset --soft HEAD^ Will keep the modified changes in your working tree.

git reset --hard HEAD^ WILL THROW AWAY THE CHANGES YOU MADE !!!

It will bust the cache once, after the client has downloaded the resource every other response will be served from client cache unless:

1. the v parameter is updated.
2. the client clears their cache

you can use the left_on and right_on options as follows:

pd.merge(frame_1, frame_2, left_on='county_ID', right_on='countyid')

I was not sure from the question if you only wanted to merge if the key was in the left hand dataframe. If that is the case then the following will do that (the above will in effect do a many to many merge)

pd.merge(frame_1, frame_2, how='left', left_on='county_ID', right_on='countyid')

This may help you as well. This is a conditional statement that will fill the cell with a default date if it is empty but will subtract one hour if it is a valid date/time and put it into the cell.

=IF((Sheet1!C4)="",DATE(1999,1,1),Sheet1!C4-TIME(1,0,0))

You can also substitute TIME with DATE to add or subtract a date or time.

function openInNewTab(href) {
  Object.assign(document.createElement('a'), {
    target: '_blank',
    href: href,
  }).click();
}

It creates a virtual a element, gives it target="_blank" so it opens in a new tab, gives it proper url href and then clicks it.

and then you can use it like:

openInNewTab("https://google.com"); 

Important note:

openInNewTab (as well as any other solution on this page) must be called during the so-called 'trusted event' callback - eg. during click event (not necessary in callback function directly, but during click action). Otherwise opening a new page will be blocked by the browser

If you call it manually at some random moment (e.g., inside an interval or after server response) - it might be blocked by the browser (which makes sense as it'd be a security risk and might lead to poor user experience)

It simply means that when git inspects the actual content of the file (it doesn't know that any given extension is not a binary file - you can use the attributes file if you want to tell it explicitly - see the man pages).

Having inspected the file's contents it has seen stuff that isn't in basic ascii characters. Being UTF16 I expect that it will have 'funny' characters so it thinks it's binary.

There are ways of telling git if you have internationalisation (i18n) or extended character formats for the file. I'm not sufficiently up on the exact method for setting that - you may need to RT[Full]M ;-)

Edit: a quick search of SO found can-i-make-git-recognize-a-utf-16-file-as-text which should give you a few clues.

The Java open source solution is Apache POI. Maybe there is a way to setup interop here, but I don't know enough about Java to answer that.

When I explored this problem I ended up using the Interop assemblies.

To get the value just use this:

<select id ="ari_select" onchange = "getvalue()">
<option value = "1"></option>
<option value = "2"></option>
<option value = "3"></option>
<option value = "4"></option>
</select>

<script>
function getvalue()
{
    alert($("#ari_select option:selected").val()); 
}
</script>

this will fetch the values

Here's what works for me to get the line number in Python 3.7.3 in VSCode 1.39.2 (dmsg is my mnemonic for debug message):

import inspect

def dmsg(text_s):
    print (str(inspect.currentframe().f_back.f_lineno) + '| ' + text_s)

To call showing a variable name_s and its value:

name_s = put_code_here
dmsg('name_s: ' + name_s)

Output looks like this:

37| name_s: value_of_variable_at_line_37

the mySql blob class has the following function :

blob.getBytes

use it like this:

//(assuming you have a ResultSet named RS)
Blob blob = rs.getBlob("SomeDatabaseField");

int blobLength = (int) blob.length();  
byte[] blobAsBytes = blob.getBytes(1, blobLength);

//release the blob and free up memory. (since JDBC 4.0)
blob.free();

I worked with Unity and had some problem with the BeginConnect and other async methods from socket.

There is something than I don't understand but the code samples before doesn't work for me.

So I wrote this piece of code to make it work. I test it on an adhoc network with android and pc, also in local on my computer. Hope it can help.

Please see my project of the cross-browser filter of value of the text input element on your web page using JavaScript language: Input Key Filter . You can filter the value as an integer number, a float number, or write a custom filter, such as a phone number filter. See an example of code of input an integer number:

var value1 = 1;
var value2 = 2;
var value3 = 3;

myFunction(value1,value2,value3, function(value2, value3){
    if (value2 && value3) {
        //Do some stuff
        alert( value2 + '-' + value3 );
    }    
});

There's a facility to have a separate style sheet for print, using

 <link type="text/css" rel="stylesheet" media="print" href="print.css">

I don't know if it does what you want though.

Primary keys always need to be unique, foreign keys need to allow non-unique values if the table is a one-to-many relationship. It is perfectly fine to use a foreign key as the primary key if the table is connected by a one-to-one relationship, not a one-to-many relationship.

A FOREIGN KEY constraint does not have to be linked only to a PRIMARY KEY constraint in another table; it can also be defined to reference the columns of a UNIQUE constraint in another table.

CREATE OR REPLACE PROCEDURE ADDEMP
    (xml IN CLOB)
AS
BEGIN
    INSERT INTO EMPLOYEE (EMPID,EMPNAME,EMPDETAIL,CREATEDBY,CREATED)
    SELECT 
        ExtractValue(column_value,'/ROOT/EMPID') AS EMPID
       ,ExtractValue(column_value,'/ROOT/EMPNAME') AS EMPNAME
       ,ExtractValue(column_value,'/ROOT/EMPDETAIL') AS EMPDETAIL
       ,ExtractValue(column_value,'/ROOT/CREATEDBY') AS CREATEDBY
       ,ExtractValue(column_value,'/ROOT/CREATEDDATE') AS CREATEDDATE
    FROM   TABLE(XMLSequence( XMLType(xml))) XMLDUMMAY;

    COMMIT;
END;

A property that has only a getter is said to be readonly. Cause no setter is provided, to change the value of the property (from outside).

C# has has a keyword readonly, that can be used on fields (not properties). A field that is marked as "readonly", can only be set once during the construction of an object (in the constructor).

private string _name = "Foo"; // field for property Name;
private bool _enabled = false; // field for property Enabled;

public string Name{ // This is a readonly property.
  get {
    return _name;  
  }
}

public bool Enabled{ // This is a read- and writeable property.
  get{
    return _enabled;
  }
  set{
    _enabled = value;
  }
} 

I'm pretty sure you can't simply add on delete cascade to an existing foreign key constraint. You have to drop the constraint first, then add the correct version. In standard SQL, I believe the easiest way to do this is to

• start a transaction,
• drop the foreign key,
• add a foreign key with on delete cascade, and finally
• commit the transaction

Repeat for each foreign key you want to change.

But PostgreSQL has a non-standard extension that lets you use multiple constraint clauses in a single SQL statement. For example

alter table public.scores
drop constraint scores_gid_fkey,
add constraint scores_gid_fkey
   foreign key (gid)
   references games(gid)
   on delete cascade;

If you don't know the name of the foreign key constraint you want to drop, you can either look it up in pgAdminIII (just click the table name and look at the DDL, or expand the hierarchy until you see "Constraints"), or you can query the information schema.

select *
from information_schema.key_column_usage
where position_in_unique_constraint is not null

Just give an id to the element and process it normally eg:

<div id="dv">
<a href="#"></a>
<span></span>
</div>

Now you can do like:

var div = document.getElementById('dv');
div.appendChild(......);

Or with jQuery:

$('#dv').get(0).appendChild(........);

Create a function that takes a UILabel instance. and returns CGSize

CGSize constraint = CGSizeMake(label.frame.size.width , 2000.0);
// Adjust according to requirement

CGSize size;
if([[[UIDevice currentDevice] systemVersion] floatValue] >= 7.0){

    NSRange range = NSMakeRange(0, [label.attributedText length]);

    NSDictionary *attributes = [label.attributedText attributesAtIndex:0 effectiveRange:&range];
    CGSize boundingBox = [label.text boundingRectWithSize:constraint options: NSStringDrawingUsesLineFragmentOrigin attributes:attributes context:nil].size;

    size = CGSizeMake(ceil(boundingBox.width), ceil(boundingBox.height));
}
else{
    size = [label.text sizeWithFont:label.font constrainedToSize:constraint lineBreakMode:label.lineBreakMode];
}

return size;

You could try the somewhat dangerous: taskkill /IM cmd.exe ..dangerous bcz that will kill the cmd that is open and any cmd's opened before it.

Or add a verification to confirm that you had the right cmd.exe and then kill it via PID, such as this:

set loc=%time%%random%
title=%loc%
for /f "tokens=2 delims= " %%A in ('tasklist /v ^| findstr /i "%loc%"') do (taskkill /PID %%A) 

Substitute (pslist &&A) or (tasklist /FI "PID eq %%A") for the (taskkill /PID %%A) if you want to check it first (and maybe have pstools installed).

First convert this structure to a "dictionary" object:

dict = {}
json.forEach(function(x) {
    dict[x.code] = x.name
})

and then simply

countryName = dict[countryCode]

For a list of countries this doesn't matter much, but for larger lists this method guarantees the instant lookup, while the naive searching will depend on the list size.

I would use

def example(arg1, arg2, arg3):
     if arg1 == 1 and arg2 == 2 and arg3 == 3:
          print("Example Text")

The and operator is identical to the logic gate with the same name; it will return 1 if and only if all of the inputs are 1. You can also use or operator if you want that logic gate.

EDIT: Actually, the code provided in your post works fine with me. I don't see any problems with that. I think that this might be a problem with your Python, not the actual language.

Do note that PostgreSQL 9.0 (today in beta testing) will have a simple way to do that:

test=> GRANT SELECT ON ALL TABLES IN SCHEMA public TO joeuser;

As well for correctness of using == you can just unbox one of compared Integer values before doing == comparison, like:

if ( firstInteger.intValue() == secondInteger ) {..

The second will be auto unboxed (of course you have to check for nulls first).

I'm assuming you've got a nice fat USB HD and a good connection to the net. You can use apt-mirror to essentially create your own debian mirror.
