Use FileSaver.js. It supports Chrome, Edge, Firefox, and IE 10+ (and probably IE < 10 with a few "polyfills" - see Note 4). FileSaver.js implements the saveAs() FileSaver interface in browsers that do not natively support it:
     https://github.com/eligrey/FileSaver.js

Minified version is really small at < 2.5KB, gzipped < 1.2KB.

Usage:

/* TODO: replace the blob content with your byte[] */
var blob = new Blob([yourBinaryDataAsAnArrayOrAsAString], {type: "application/octet-stream"});
var fileName = "myFileName.myExtension";
saveAs(blob, fileName);

You might need Blob.js in some browsers (see Note 3). Blob.js implements the W3C Blob interface in browsers that do not natively support it. It is a cross-browser implementation:
     https://github.com/eligrey/Blob.js

Consider StreamSaver.js if you have files larger than blob's size limitations.

Tested on Chrome, Edge, Firefox, and IE 11 (use FileSaver.js for supporting IE 11).
You can also save from a canvas element. See https://github.com/eligrey/FileSaver.js#saving-a-canvas.

Downloadify is a Flash-based polyfill for supporting IE6-9: https://github.com/dcneiner/downloadify (I don't recommend Flash-based solutions in general, though.)

Note 5: Creating a BLOB from a Base64 string in JavaScript

Note 6: FileSaver.js examples: https://github.com/eligrey/FileSaver.js#examples

They have wrapped most stuff need to solve your problem, one of the tests looks like this:

String filename = CSSURLEmbedderTest.class.getResource("folder.png").getPath().replace("%20", " ");
String code = "background: url(folder.png);";

StringWriter writer = new StringWriter();
embedder = new CSSURLEmbedder(new StringReader(code), true);
embedder.embedImages(writer, filename.substring(0, filename.lastIndexOf("/")+1));

String result = writer.toString();
assertEquals("background: url(" + folderDataURI + ");", result);

They serve the actual image inside CSS so there will be less HTTP requests per page.

Update Swift 4.2

Here, for instance, we encrypt a string to base64encoded string. And then we decrypt the same to a readable string. (That would be same as our input string).

In my case, I use this to encrypt a string and embed that to QR Code. Then another party scan that and decrypt the same. So intermediate won't understand the QR codes.

Step 1: Encrypt a string "Encrypt My Message 123"

Step 2: Encrypted base64Encoded string : +yvNjiD7F9/JKmqHTc/Mjg== (The same printed on QR code)

Step 3: Scan and decrypt the string "+yvNjiD7F9/JKmqHTc/Mjg=="

Step 4: It comes final result - "Encrypt My Message 123"

Functions for Encrypt & Decrypt

func encryption(stringToEncrypt: String) -> String{
    let key = "MySecretPKey"
    //let iv = "92c9d2c07a9f2e0a"
    let data = stringToEncrypt.data(using: .utf8)
    let keyD = key.data(using: .utf8)
    let encr = (data as NSData?)!.aes128EncryptedData(withKey: keyD)
    let base64String: String = (encr as NSData?)!.base64EncodedString(options: NSData.Base64EncodingOptions(rawValue: 0))
    print(base64String)
    return base64String
}

func decryption(encryptedString:String) -> String{
    let key = "MySecretPKey"
    //let iv = "92c9d2c07a9f2e0a"
    let keyD = key.data(using: .utf8)
    let decrpStr = NSData(base64Encoded: encryptedString, options: NSData.Base64DecodingOptions(rawValue: 0))
    let dec = (decrpStr)!.aes128DecryptedData(withKey: keyD)
    let backToString = String(data: dec!, encoding: String.Encoding.utf8)
    print(backToString!)
    return backToString!
}

Usage:

    let enc = encryption(stringToEncrypt: "Encrypt My Message 123")
    let decryptedString = decryption(encryptedString: enc)
    print(decryptedString) 

Classes for supporting AES encrypting functions, these are written in Objective-C. So for swift, you need to use bridge header to support these.

I hope that helps.

Thanks!!!

Swift version of new implementation is :

 let alert = UIAlertController(title: "Oops!", message:"your message", preferredStyle: .Alert)
 alert.addAction(UIAlertAction(title: "Okay.", style: .Default) { _ in })
 self.presentViewController(alert, animated: true){}

I ran in to the exact same issue. I have an ASP.NET checkbox

<asp:CheckBox ID="chkBox1" CssClass='cssChkBox1' runat="server" />

In the jQuery code I used the following selector to check if the checkbox was checked or not, and it seems to work like a charm.

if ($("'.cssChkBox1 input[type=checkbox]'").is(':checked'))
{ ... } else { ... }

I'm sure you can also use the ID instead of the CssClass,

if ($("'#cssChkBox1 input[type=checkbox]'").is(':checked'))
{ ... } else { ... }

I hope this helps you.

As answered in the official Python FAQ:

b = a[:]

If you need one single regex, try:

(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*\W)

A short explanation:

(?=.*[a-z])        // use positive look ahead to see if at least one lower case letter exists
(?=.*[A-Z])        // use positive look ahead to see if at least one upper case letter exists
(?=.*\d)           // use positive look ahead to see if at least one digit exists
(?=.*\W])        // use positive look ahead to see if at least one non-word character exists

And I agree with SilentGhost, \W might be a bit broad. I'd replace it with a character set like this: [-+_!@#$%^&*.,?] (feel free to add more of course!)

Update 3: There is an official api added for this, please use ActivityLifecycleCallbacks instead.

JsonPath jsonPathEvaluator = response.jsonPath();
return jsonPathEvaluator.get("user_id").toString();

You can achieve this by putting the alt tag in the div were your image will appear.

Example:

<div id="yourImage" alt="nameOfImage"></div>

As BalusC indicated, the actionListener by default swallows exceptions, but in JSF 2.0 there is a little more to this. Namely, it doesn't just swallows and logs, but actually publishes the exception.

This happens through a call like this:

context.getApplication().publishEvent(context, ExceptionQueuedEvent.class,                                                          
    new ExceptionQueuedEventContext(context, exception, source, phaseId)
);

The default listener for this event is the ExceptionHandler which for Mojarra is set to com.sun.faces.context.ExceptionHandlerImpl. This implementation will basically rethrow any exception, except when it concerns an AbortProcessingException, which is logged. ActionListeners wrap the exception that is thrown by the client code in such an AbortProcessingException which explains why these are always logged.

This ExceptionHandler can be replaced however in faces-config.xml with a custom implementation:

<exception-handlerfactory>
   com.foo.myExceptionHandler
</exception-handlerfactory>

Instead of listening globally, a single bean can also listen to these events. The following is a proof of concept of this:

@ManagedBean
@RequestScoped
public class MyBean {

    public void actionMethod(ActionEvent event) {

        FacesContext.getCurrentInstance().getApplication().subscribeToEvent(ExceptionQueuedEvent.class, new SystemEventListener() {

        @Override
        public void processEvent(SystemEvent event) throws AbortProcessingException {
            ExceptionQueuedEventContext content = (ExceptionQueuedEventContext)event.getSource();
            throw new RuntimeException(content.getException());
        }

        @Override
        public boolean isListenerForSource(Object source) {
            return true;
        }
        });

        throw new RuntimeException("test");
    }

}

(note, this is not how one should normally code listeners, this is only for demonstration purposes!)

Calling this from a Facelet like this:

<html xmlns="http://www.w3.org/1999/xhtml"
    xmlns:h="http://java.sun.com/jsf/html"
    xmlns:f="http://java.sun.com/jsf/core">
    <h:body>
        <h:form>
            <h:commandButton value="test" actionListener="#{myBean.actionMethod}"/>
        </h:form>
    </h:body>
</html>

Will result in an error page being displayed.

An xml document is made of nested elements. An element begins at its opening tag and ends at its closing tag. You're probably seen <body> and </body> in html. Everything between the opening and closing tags is the element's content. If an element is defined by a self-closing tag (eg. <br/>) then its content is empty.

Opening tags can also specify attributes, eg. <p class="rant">. In this example the attribute name is 'class' and its value 'rant'.

The XML language has no such thing as a 'node'. Read the spec, the word doesn't occur.

Some people use the word 'node' informally to mean element, which is confusing because some parsers also give the word a technical meaning (identifying 'text nodes' and 'element nodes'). The exact meaning depends on the parser, so the word is ill-defined unless you state what parser you are using. If you mean element, say 'element'.

I experienced such problem after setting HttpComponentsClientHttpRequestFactory for my rest template.

Setting OkHttpClientHttpRequestFactory should solve problem with trash logging.

toFixed() method formats a number using fixed-point notation. Read MDN Web Docs for full reference.

var fval = 4;

console.log(fval.toFixed(2)); // prints 4.00

I had similar problem before. But this was resolved when I started using hostname instead of IP address in my connection string.

try :

sudo su

then

npm i npx 
or 
npi i -g npx

check your npx version by

npx -v

Mmh ... there are many ways. I answer another network discovery question, and I write a little getting started.

Some tcpip stacks reply to icmp broadcasts. So you can try a PING to your network broadcast address.

For example, you have ip 192.168.1.1 and subnet 255.255.255.0

1. ping 192.168.1.255
2. stop the ping after 5 seconds
3. watch the devices replies : arp -a

Note : on step 3. you get the lists of the MAC-to-IP cached entries, so there are also the hosts in your subnet you exchange data to in the last minutes, even if they don't reply to icmp_get.

Note (2) : now I am on linux. I am not sure, but it can be windows doesn't reply to icm_get via broadcast.

Is it the only one device attached to your pc ? Is it a router or another simple pc ?

"What is a “static” function in C?"

Let's start at the beginning.

It´s all based upon a thing called "linkage":

"An identifier declared in different scopes or in the same scope more than once can be made to refer to the same object or function by a process called linkage. 29)There are three kinds of linkage: external, internal, and none."

Source: C18, 6.2.2/1

"In the set of translation units and libraries that constitutes an entire program, each declaration of a particular identifier with external linkage denotes the same object or function. Within one translation unit, each declaration of an identifier with internal linkage denotes the same object or function. Each declaration of an identifier with no linkage denotes a unique entity."

Source: C18, 6.2.2/2

If a function is defined without a storage-class specifier, the function has external linkage by default:

"If the declaration of an identifier for a function has no storage-class specifier, its linkage is determined exactly as if it were declared with the storage-class specifier extern."

Source: C18, 6.2.2/5

That means that - if your program is contained of several translation units/source files (.c or .cpp) - the function is visible in all translation units/source files your program has.

This can be a problem in some cases. What if you want to use f.e. two different function (definitions), but with the same function name in two different contexts (actually the file-context).

In C and C++, the static storage-class qualifier applied to a function at file scope (not a static member function of a class in C++ or a function within another block) now comes to help and signifies that the respective function is only visible inside of the translation unit/source file it was defined in and not in the other TLUs/files.

"If the declaration of a file scope identifier for an object or a function contains the storage-class specifier static, the identifier has internal linkage. 30)"

30. A function declaration can contain the storage-class specifier static only if it is at file scope; see 6.7.1.

Source: C18, 6.2.2/3

Thus, A static function only makes sense, iff:

1. Your program is contained of several translation units/source files (.c or .cpp).

and

2. You want to limit the scope of a function to the file, in which the specific function is defined.

If not both of these requirements match, you don't need to wrap your head around about qualifying a function as static.

Side Notes:

• As already mentioned, A static function has absolutely no difference at all between C and C++, as this is a feature C++ inherited from C.

It does not matter that in the C++ community, there is a heartbreaking debate about the depreciation of qualifying functions as static in comparison to the use of unnamed namespaces instead, first initialized by a misplaced paragraph in the C++03 standard, declaring the use of static functions as deprecated which soon was revised by the committee itself and removed in C++11.

This was subject to various SO questions:

Unnamed/anonymous namespaces vs. static functions

Superiority of unnamed namespace over static?

Why an unnamed namespace is a "superior" alternative to static?

Deprecation of the static keyword... no more?

In fact, it is not deprecated per C++ standard yet. Thus, the use of static functions is still legit. Even if unnamed namespaces have advantages, the discussion about using or not using static functions in C++ is subject to one´s one mind (opinion-based) and with that not suitable for this website.

Doing it in one bulk read:

import re

textfile = open(filename, 'r')
filetext = textfile.read()
textfile.close()
matches = re.findall("(<(\d{4,5})>)?", filetext)

Line by line:

import re

textfile = open(filename, 'r')
matches = []
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += reg.findall(line)
textfile.close()

But again, the matches that returns will not be useful for anything except counting unless you added an offset counter:

import re

textfile = open(filename, 'r')
matches = []
offset = 0
reg = re.compile("(<(\d{4,5})>)?")
for line in textfile:
    matches += [(reg.findall(line),offset)]
    offset += len(line)
textfile.close()

But it still just makes more sense to read the whole file in at once.

A grep-less solution, works for me:

MY_LIST=$( cat /path/to/my_list.txt )



if [[ "${MY_LIST}" == *"${NEW_DIRECTORY_NAME}"* ]]; then
  echo "It's there!"
else
echo "its not there"
fi

i am using Font Awesome 4.3.0 just linking from maxcdn works as mentioned here,

but to host in your server putting fonts and css in same folder worked for me, like this

then just link the css:

<link href="~/fonts/font-awesome.min.css" rel="stylesheet" />

hope helps someone.

If you're running IIS 8.5 on Windows 8, or Server 2012, you might find that running mvc 4/5 (.net 4.5) doesn't work in a virtual directory. If you create a local host entry in the host file to point back to your local machine and then point a new local IIS website to that folder (with the matching host header entry) you'll find it works then.

This answer is just useful to understand how you can make delay using JQuery delay function.

Imagine you have an alert and you want to set the alert text then show the alert and after a few seconds hide it.

Here is the simple solution:

$(".alert-element").html("I'm the alert text").fadeIn(500).delay(5000).fadeOut(1000);

It is completely simple:

1. .html() will change the text of .alert-element
2. .fadeIn(500) will fade in after 500 milliseconds
3. JQuery delay(5000) function will make 5000 milliseconds of delay before calling next function
4. .fadeOut(1000) at the end of the statement will fade out the .alert-element

Use the range's NumberFormat property to force the format of the range like this:

Sheet1.Range("A2", "A50000").NumberFormat = "yyyy-mm-dd"

In order to remove any URL within a string in Python, you can use this RegEx function :

import re

def remove_URL(text):
    """Remove URLs from a text string"""
    return re.sub(r"http\S+", "", text)

You can use SVG for rounding corners and load into an ImageView and use ConstraintLayout to bring ImageView on TextView

I found that not only did I have to restart Visual Studio Code but the node server process as well before I could get a good compile.

Had the same issue today. I added the user to:

Administrative Tools -> Local Security Policy -> Local Policies -> User Rights Assignment -> Log on as a batch job

But was still getting the error. I found this post, and it turns out there's also this setting that I had to remove the user from (not sure how it got in there):

Administrative Tools -> Local Security Policy -> Local Policies -> User Rights Assignment -> Deny log on as a batch job

So just be aware that you may need to check both policies for the user.

Using base R aggregate function:

aggregate(value ~ name, dat1, I)

# name           value.1  value.2  value.3  value.4
#1 firstName      0.4145  -0.4747   0.0659   -0.5024
#2 secondName    -0.8259   0.1669  -0.8962    0.1681

Plese try this:

var sizeInKB = input.files[0].size/1024; //Normally files are in bytes but for KB divide by 1024 and so on
var sizeLimit= 30;

if (sizeInKB >= sizeLimit) {
    alert("Max file size 30KB");
    return false;
}

I actually found a better way using the jQuery approach

var box = {

config:{
 color: 'red'
},

init:function(config){
 $.extend(this.config,config);
}

};

var myBox = box.init({
 color: blue
});

I want to make some unit test to get maximal code coverage

Code coverage should never be the goal of writing unit tests. You should write unit tests to prove that your code is correct, or help you design it better, or help someone else understand what the code is meant to do.

but I dont see how I can test my method checkIfValidElements, it returns nothing or change nothing.

Well you should probably give a few tests, which between them check that all 7 methods are called appropriately - both with an invalid argument and with a valid argument, checking the results of ErrorFile each time.

For example, suppose someone removed the call to:

method4(arg1, arg2);

... or accidentally changed the argument order:

method4(arg2, arg1);

How would you notice those problems? Go from that, and design tests to prove it.

I think you can find that in glib: http://developer.gnome.org/glib/unstable/glib-Date-and-Time-Functions.html#g-date-get-day

If you want the labels to be retained for the tooltip, but not displayed below the bars the following hack might be useful. I made this change for use on an private intranet application and have not tested it for efficiency or side-effects, but it did what I needed.

At about line 71 in chart.js add a property to hide the bar labels:

// Boolean - Whether to show x-axis labels
barShowLabels: true,

At about line 1500 use that property to suppress changing this.endPoint (it seems that other portions of the calculation code are needed as chunks of the chart disappeared or were rendered incorrectly if I disabled anything more than this line).

if (this.xLabelRotation > 0) {
    if (this.ctx.barShowLabels) {
        this.endPoint -= Math.sin(toRadians(this.xLabelRotation)) * originalLabelWidth + 3;
    } else {
        // don't change this.endPoint
    }
}

At about line 1644 use the property to suppress the label rendering:

if (ctx.barShowLabels) {    
    ctx.fillText(label, 0, 0);
}

I'd like to make this change to the Chart.js source but aren't that familiar with git and don't have the time to test rigorously so would rather avoid breaking anything.

Angular’s keyvalue pipe can be used, but unfortunately it sorts by key. Maps already have an order and it would be great to be able to keep it!

We can define out own pipe mapkeyvalue which preserves the order of items in the map:

import { Pipe, PipeTransform } from '@angular/core';

// Holds a weak reference to its key (here a map), so if it is no longer referenced its value can be garbage collected.
const cache = new WeakMap<ReadonlyMap<any, any>, Array<{ key: any; value: any }>>();

@Pipe({ name: 'mapkeyvalue', pure: true })
export class MapKeyValuePipe implements PipeTransform {
  transform<K, V>(input: ReadonlyMap<K, V>): Iterable<{ key: K; value: V }> {
    const existing = cache.get(input);
    if (existing !== undefined) {
      return existing;
    }

    const iterable = Array.from(input, ([key, value]) => ({ key, value }));
    cache.set(input, iterable);
    return iterable;
  }
}

It can be used like so:

<mat-select>
  <mat-option *ngFor="let choice of choicesMap | mapkeyvalue" [value]="choice.key">
    {{ choice.value }}
  </mat-option>
</mat-select>

1. Set a breakpoint as usual
2. Right click on the breakpoint and select Condition
3. You'll see a dialog that says "Breakpoint Condition"
4. Put a condition in the field e.g. "i==5"

The breakpoint will only get hit when i is 5.

Two ways that can be works

1: Uninstall app from mobile device manually

2: Open command prompt , trace path of adband execute following command

adb uninstall your_package_name

Use the -e argument and the escape character \n:

echo -e "This will generate a next line \nThis new line is the result"

If you want to execute each command only if the previous one succeeded, then combine them using the && operator:

cd /my_folder && rm *.jar && svn co path to repo && mvn compile package install

If one of the commands fails, then all other commands following it won't be executed.

If you want to execute all commands regardless of whether the previous ones failed or not, separate them with semicolons:

cd /my_folder; rm *.jar; svn co path to repo; mvn compile package install

In your case, I think you want the first case where execution of the next command depends on the success of the previous one.

You can also put all commands in a script and execute that instead:

#! /bin/sh
cd /my_folder \
&& rm *.jar \
&& svn co path to repo \
&& mvn compile package install

(The backslashes at the end of the line are there to prevent the shell from thinking that the next line is a new command; if you omit the backslashes, you would need to write the whole command in a single line.)

Save that to a file, for example myscript, and make it executable:

chmod +x myscript

You can now execute that script like other programs on the machine. But if you don't place it inside a directory listed in your PATH environment variable (for example /usr/local/bin, or on some Linux distributions ~/bin), then you will need to specify the path to that script. If it's in the current directory, you execute it with:

./myscript

The commands in the script work the same way as the commands in the first example; the next command only executes if the previous one succeeded. For unconditional execution of all commands, simply list each command on its own line:

#! /bin/sh
cd /my_folder
rm *.jar
svn co path to repo
mvn compile package install

isset() is not an effective way to validate text inputs and text boxes from a HTML form

You can rewrite that as "isset() is not a way to validate input." To validate input, use PHP's filter extension. filter_has_var() will tell you whether the variable exists while filter_input() will actually filter and/or sanitize the input.

Note that you don't have to use filter_has_var() prior to filter_input() and if you ask for a variable that is not set, filter_input() will simply return null.

See, here you can get only date by passing a format string. You can get a different date format as per your requirement as given below for current date:

DateTime.Now.ToString("M/d/yyyy");

Result : "9/1/2015"

DateTime.Now.ToString("M-d-yyyy");

Result : "9-1-2015"

DateTime.Now.ToString("yyyy-MM-dd");

Result : "2015-09-01"

DateTime.Now.ToString("yyyy-MM-dd hh:mm:ss");

Result : "2015-09-01 09:20:10"

For more details take a look at MSDN reference for Custom Date and Time Format Strings

5. Something else - there must be other solutions out there?

You're right, there is! And it is called JWT (JSON Web Tokens).

JSON Web Token (JWT) is an open standard (RFC 7519) that defines a compact and self-contained way for securely transmitting information between parties as a JSON object. This information can be verified and trusted because it is digitally signed. JWTs can be signed using a secret (with the HMAC algorithm) or a public/private key pair using RSA.

I highly recommend looking into JWTs. They're a much simpler solution to the problem when compared against alternative solutions.

https://jwt.io/introduction/

try this:

.test {
    position:absolute;
    background:blue;
    width:200px;
    height:200px;
    top:40px;
    transition:left 1s linear;
    left: 0;
}

They are usually stored in the following folders:

/bin/
/usr/bin/
/sbin/
/usr/sbin/

If you're not sure, use the which command:

~$ which firefox
/usr/bin/firefox

just give rowId and type of data that is going to be update in ContentValues.

public void updateStatus(String id , int status){

SQLiteDatabase db = this.getWritableDatabase();

ContentValues data = new ContentValues();

data.put("status", status);

db.update(TableName, data, "columnName" + " = "+id , null);

}

I used the above command line as follow: update TABLE-NAME set FIELD = replace(FIELD, 'And', 'and'); the purpose was to replace And with and ("A" should be lowercase). The problem is it cannot find the "And" in database, but if I use like "%And%" then it can find it along with many other ands that are part of a word or even the ones that are already lowercase.

I would use the jQuery validation plugin for a few reasons.

You validated, ok great, now what? You need to display the error, handle erasing it when it is valid, displaying how many errors total perhaps? There are lots of things it can handle for you, no need to re-invent the wheel.

Also, another huge benefit is it's hosted on a CDN, the current version at the time of this answer can be found here: http://www.asp.net/ajaxLibrary/CDNjQueryValidate16.ashx This means faster load times for the client.

function msToTime(duration) {_x000D_

    seconds = Math.floor((duration / 1000) % 60),_x000D_

console.log(msToTime(300000))

A complete solution is here

it's explained very nice with sample code. However, be careful that it does not close the application.Add the line Application.Current.Shutdown(); to gracefully close the app.

I was able to achieve this using an immediately-invoked function and require statement.

const something = (() => (
  condition ? require('something') : null
))();

if(something) {
  something.doStuff();
}

Starting in version 0.7.9 you can use the filter operator .isnot instead of comparing constraints, like this:

query.filter(User.name.isnot(None))

This method is only necessary if pep8 is a concern.

DotNetCoders has a starter article on it: http://www.dotnetcoders.com/web/Articles/ShowArticle.aspx?article=50. They talk about how to set up the switches in the configuration file and how to write the code, but it is pretty old (2002).

There's another article on CodeProject: A Treatise on Using Debug and Trace classes, including Exception Handling, but it's the same age.

CodeGuru has another article on custom TraceListeners: Implementing a Custom TraceListener

With respect to those special characters not being taken into account by simpler checks such as /[a-zA-Z]/.test(c), it can be beneficial to leverage ECMAScript case transformation (toUpperCase). It will take into account non-ASCII Unicode character classes of some foreign alphabets.

function isLetter(c) {
  return c.toLowerCase() != c.toUpperCase();
}

NOTE: this solution will work only for most Latin, Greek, Armenian and Cyrillic scripts. It will NOT work for Chinese, Japanese, Arabic, Hebrew and most other scripts.

One more option is to add the path of the privatekey file like this in terminal:

ssh-add "path to the privatekeyfile"

and then execute the pull command

Try mpstat from the sysstat package

> sudo apt-get install sysstat
Linux 3.0.0-13-generic (ws025)  02/10/2012  _x86_64_    (2 CPU)

Then some cutor grepto parse the info you need:

mpstat | grep -A 5 "%idle" | tail -n 1 | awk -F " " '{print 100 -  $ 12}'a

I would store the timespan.TotalSeconds in a float and then retrieve it using Timespan.FromSeconds(totalSeconds).

Depending on the resolution you need you could use TotalMilliseconds, TotalMinutes, TotalDays.

You could also adjust the precision of your float in the database.

It's not an exact value... but the nice thing about this is that it's easy to read and calculate in simple queries.

This works as of android 7.1.1, non-rooted

adb shell am start -a android.intent.action.MAIN -n com.android.settings/.wifi.WifiSettings && adb shell input keyevent 23 && adb shell input keyevent 23

This will launch the activity and then send the DPAD center keyevent. I added another DPAD center as an experiment to see if you can enable it in the same way.

I'm coming to python from R, and R's head() function wraps lines in a really convenient way for looking at data:

I developed the following little python function to mimic this functionality:

def rhead(x, nrow = 6, ncol = 4):
    pd.set_option('display.expand_frame_repr', False)
    seq = np.arange(0, len(x.columns), ncol)
    for i in seq:
        print(x.loc[range(0, nrow), x.columns[range(i, min(i+ncol, len(x.columns)))]])
    pd.set_option('display.expand_frame_repr', True)

(it depends on pandas and numpy, obviously)

Similarly, if you wanted to redirect to a sub-folder instead of a sub-domain, do the following:

Working off of Kevin's great solution you can add this to the .htaccess file in your site's root directory:

    <IfModule mod_rewrite.c>
        RewriteBase /
        RewriteEngine On

        # Check if mobile=1 is set and set cookie 'mobile' equal to 1
        RewriteCond %{QUERY_STRING} (^|&)mobile=1(&|$)
        RewriteRule ^ - [CO=mobile:1:%{HTTP_HOST}]

        # Check if mobile=0 is set and set cookie 'mobile' equal to 0
        RewriteCond %{QUERY_STRING} (^|&)mobile=0(&|$)
        RewriteRule ^ - [CO=mobile:0:%{HTTP_HOST}]

        # cookie can't be set and read in the same request so check
        RewriteCond %{QUERY_STRING} (^|&)mobile=0(&|$)
        RewriteRule ^ - [S=1]

        # Check if this looks like a mobile device
        RewriteCond %{HTTP:x-wap-profile} !^$ [OR]
        RewriteCond %{HTTP_USER_AGENT} "android|blackberry|ipad|iphone|ipod|iemobile|opera mobile|palmos|webos|googlebot-mobile" [NC,OR]
        RewriteCond %{HTTP:Profile}       !^$

        # Check if we're not already on the mobile site
        RewriteCond %{HTTP_HOST}          !^m\.
        # Check to make sure we haven't set the cookie before
        RewriteCond %{HTTP:Cookie}        !\mobile=0(;|$)
        # Now redirect to the mobile site
        RewriteRule ^ http://www.mysite.com/m/ [R]
    </IfModule>

Then, in the /m/ folder, add or create an .htaccess with the following:

    #Begin user agent loop fix

         RewriteEngine Off
         RewriteBase /

    #End user agent loop fix 

I know it's not a direct answer to the question, but somebody (like me) might stumble upon this question and wonder how that method would be accomplished as well.

This is what I use for lists:

config file content:

[sect]
alist = a
        b
        c

code :

l = config.get('sect', 'alist').split('\n')

it work for strings

in case of numbers

config content:

nlist = 1
        2
        3

code:

nl = config.get('sect', 'alist').split('\n')
l = [int(nl) for x in nl]

thanks.

This configuration is working for me:

set termout off
set verify off
set trimspool on
set linesize 200
set longchunksize 200000
set long 200000
set pages 0
column txt format a120

The column format definition with the linesize option helped to avoid the truncation at 80 chars.

There are many suggestions but I found two of them most common.

Re. JAVA_OPTS

I first tried export JAVA_OPTS="-Dhttps.protocols=SSLv3,TLSv1,TLSv1.1,TLSv1.2" on command line before startup of program but it didn't work for me.

Re. constructor

Then I added the following code in the startup class constructor and it worked for me.

try {
        SSLContext ctx = SSLContext.getInstance("TLSv1.2");
        ctx.init(null, null, null);
        SSLContext.setDefault(ctx);
} catch (Exception e) {
        System.out.println(e.getMessage());
}

Frankly, I don't know in detail why ctx.init(null, null, null); but all (SSL/TLS) is working fine for me.

Re. System.setProperty

There is one more option: System.setProperty("https.protocols", "SSLv3,TLSv1,TLSv1.1,TLSv1.2");. It will also go in code but I've not tried it.

for multiple classes situation, as @jbojcic mentioned above, you can use:

host: {class: 'A B C'}

Postgres hasn't implemented an equivalent to INSERT OR REPLACE. From the ON CONFLICT docs (emphasis mine):

It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.

Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE applies more generally, since it lets you set new values based on preexisting data. For example:

INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;

Here's a solution that has worked pretty well for me:

List<String> lines = Arrays.asList(
    new Scanner(new File(file)).useDelimiter("\\Z").next().split("\\r?\\n")
);

If you don't want empty lines, you can also do:

List<String> lines = Arrays.asList(
    new Scanner(new File(file)).useDelimiter("\\Z").next().split("[\\r\\n]+")
);

my is used for local variables, whereas our is used for global variables.

How about the split command?

split -l 200000 mybigfile.txt

I think this should point you towards the right direction:

import java.beans.*

for (PropertyDescriptor pd : Introspector.getBeanInfo(Foo.class).getPropertyDescriptors()) {
  if (pd.getReadMethod() != null && !"class".equals(pd.getName()))
    System.out.println(pd.getReadMethod().invoke(foo));
}

Note that you could create BeanInfo or PropertyDescriptor instances yourself, i.e. without using Introspector. However, Introspector does some caching internally which is normally a Good Thing (tm). If you're happy without a cache, you can even go for

// TODO check for non-existing readMethod
Object value = new PropertyDescriptor("name", Person.class).getReadMethod().invoke(person);

However, there are a lot of libraries that extend and simplify the java.beans API. Commons BeanUtils is a well known example. There, you'd simply do:

Object value = PropertyUtils.getProperty(person, "name");

BeanUtils comes with other handy stuff. i.e. on-the-fly value conversion (object to string, string to object) to simplify setting properties from user input.

A little bit off topic but useful is the pythonic numpy approach. Its robust and fast but just does compare pixels and not the objects or data the picture contains (and it requires images of same size and shape):

A very simple and fast approach to do this without openCV and any library for computer vision is to norm the picture arrays by

import numpy as np
picture1 = np.random.rand(100,100)
picture2 = np.random.rand(100,100)
picture1_norm = picture1/np.sqrt(np.sum(picture1**2))
picture2_norm = picture2/np.sqrt(np.sum(picture2**2))

After defining both normed pictures (or matrices) you can just sum over the multiplication of the pictures you like to compare:

1) If you compare similar pictures the sum will return 1:

In[1]: np.sum(picture1_norm**2)
Out[1]: 1.0

2) If they aren't similar, you'll get a value between 0 and 1 (a percentage if you multiply by 100):

In[2]: np.sum(picture2_norm*picture1_norm)
Out[2]: 0.75389941124629822

Please notice that if you have colored pictures you have to do this in all 3 dimensions or just compare a greyscaled version. I often have to compare huge amounts of pictures with arbitrary content and that's a really fast way to do so.

With ?# 6.0

var myDict = new Dictionary<string, string>
{
    ["Key1"] = "Value1",
    ["Key2"] = "Value2"
};

Non greedy search in vim is done using {-} operator. Like this:

%s/style=".\{-}"//g

just try:

:help non-greedy

@VonC already gave a very nice answer, but for completeness here is a little script I have been using---and which also nukes any errand Docker processes should you have some:

#!/bin/bash

imgs=$(docker images | awk '/<none>/ { print $3 }')
if [ "${imgs}" != "" ]; then
   echo docker rmi ${imgs}
   docker rmi ${imgs}
else
   echo "No images to remove"
fi

procs=$(docker ps -a -q --no-trunc)
if [ "${procs}" != "" ]; then
   echo docker rm ${procs}
   docker rm ${procs}
else
   echo "No processes to purge"
fi

require 'date'

date = DateTime.parse("2011-05-19 10:30:14")
formatted_date = date.strftime('%a %b %d %H:%M:%S %Z %Y')

See strftime() for more information about formatting dates.

What you want is .empty not .empty() to fully mimics Ruby :

     Object.defineProperty( Array.prototype, 'empty', {
           get: function ( ) { return this.length===0 }
      } );    

then

[].empty //true
[3,2,8].empty //false

For any , see my answer here

This is so called file local variables, that are understood by Emacs and set correspondingly. See corresponding section in Emacs manual - you can define them either in header or in footer of file

this work for me, accesing data from root. use double slash to access address.

dataset = read.csv('C:\\Users\\Desktop\\Machine Learning\\Data.csv')

Grouped Array of Object in typescript with this:

groupBy (list: any[], key: string): Map<string, Array<any>> {
    let map = new Map();
    list.map(val=> {
        if(!map.has(val[key])){
            map.set(val[key],list.filter(data => data[key] == val[key]));
        }
    });
    return map;
});

Yes, indeed. The datepicker has the maxdate property that you can set when you initialize it.

Here's the codez

$("#datepicker").datepicker({ maxDate: new Date, minDate: new Date(2007, 6, 12) });

SELECT *, CONVERT(int, your_column) AS your_column_int
FROM your_table
ORDER BY your_column_int

OR

SELECT *, CAST(your_column AS int) AS your_column_int
FROM your_table
ORDER BY your_column_int

Both are fairly portable I think.

I upgraded to Windows 10 x64 (from Windows 7 x64), had a VirtualBox Windows 10 x64 VM, but got the VT-x error. My BIOS was enabled, settings - everything in this post was addressed, but still got the VT-x error.

What fixed it for me was to go to Lenovo and install the latest BIOS for my W550s ThinkPad. Once the upgrade was installed, VirtualBox gave me the x64 options again with no more VT-x errors.

If you are running a W550s, the BIOS version I installed was from September 2015, "BIOS Update Utility" n11uj05w.exe, version 1.10 from the Lenovo website.

This package seems to be a good solution for the underlying issue of having non-unique IDs in your DOM across multiple components:

vue-uniq-ids

It is a trend to use components. Components are cool, they are small, obvious, easy to use and modular. Untill it comes to the id property.

Some HTML tag attributes requires using an id property, like label[for], input[form] and many of aria-* attributes. And the problem with the id is that it is not modular. If several id properties on the page will has the same value they can affect each other.

VueUniqIds helps you to get rid of this problem. It provides the set of id-related directives which value is automatically modified by adding unique string while keeping the attrbitue easy to read.

This was perfect for me. You will get the return code, stdout and stderr in a tuple.

from subprocess import Popen, PIPE

def console(cmd):
    p = Popen(cmd, shell=True, stdout=PIPE)
    out, err = p.communicate()
    return (p.returncode, out, err)

For Example:

result = console('ls -l')
print 'returncode: %s' % result[0]
print 'output: %s' % result[1]
print 'error: %s' % result[2]

OFFICE 2013 INSTRUCTIONS:

(For Windows 7 (x64) | MS Office 32-Bit)

Option 1 | Check if ability already exists | 2 minutes

1. Open VB Editor
2. Tools -> Additional Controls
3. Select "Microsoft Monthview Control 6.0 (SP6)" (if applicable)
4. Use 'DatePicker' control for VBA Userform

Option 2 | The "Monthview" Control doesn't currently exist | 5 minutes

1. Close Excel
2. Download MSCOMCT2.cab (it's a cabinet file which extracts into two useful files)
3. Extract Both Files | the .inf file and the .ocx file
4. Install | right-click the .inf file | hit "Install"
5. Move .ocx file | Move from "C:\Windows\system32" to "C:\Windows\sysWOW64"
6. Run CMD | Start Menu -> Search -> "CMD.exe" | right-click the icon | Select "Run as administrator"
7. Register Active-X File | Type "regsvr32 c:\windows\sysWOW64\MSCOMCT2.ocx"
8. Open Excel | Open VB Editor
9. Activate Control | Tools->References | Select "Microsoft Windows Common Controls 2-6.0 (SP6)"
10. Userform Controls | Select any userform in VB project | Tools->Additional Controls
11. Select "Microsoft Monthview Control 6.0 (SP6)"
12. Use 'DatePicker' control for VBA UserForm

Okay, either of these two steps should work for you if you have Office 2013 (32-Bit) on Windows 7 (x64). Some of the steps may be different if you have a different combo of Windows 7 & Office 2013.

The "Monthview" control will be your fully fleshed out 'DatePicker'. It comes equipped with its own properties and image. It works very well. Good luck.

You can use Process.GetProcesses() to get the currently running processes, then Process.Kill() to kill a process.

GROUP BY has a very specific meaning that is distinct (heh) from the DISTINCT function.

GROUP BY causes the query results to be grouped using the chosen expression, aggregate functions can then be applied, and these will act on each group, rather than the entire resultset.

Here's an example that might help:

Given a table that looks like this:

name
------
barry
dave
bill
dave
dave
barry
john

This query:

SELECT name, count(*) AS count FROM table GROUP BY name;

Will produce output like this:

name    count
-------------
barry   2
dave    3
bill    1
john    1

Which is obviously very different from using DISTINCT. If you want to group your results, use GROUP BY, if you just want a unique list of a specific column, use DISTINCT. This will give your database a chance to optimise the query for your needs.

df[df$aged <= df$laclen, ] 

Should do the trick. The square brackets allow you to index based on a logical expression.

Unless you can get PHP to label that element with a class you are better to use jQuery.

jQuery(document).ready(function () {
  $count =  jQuery("ul li").size() - 1;
  alert($count);
  jQuery("ul li:nth-child("+$count+")").css("color","red");
});

Roughly the same kinds of things you've done in C#. Calling getch() is probably the simplest.

While I realize this is a bit of an older post, I thought this might help people in a similar situation. I made a quick one line VBScript to pull info for whatever special folder you would like (no error checking though) and it works like this:

Create a file "GetShellFolder.vbs" with the following line:

WScript.Echo WScript.CreateObject("WScript.Shell").SpecialFolders(WScript.Arguments(0))

I always make sure to copy cscript.exe (32-bit version) to the same folder as the batch file I am running this from, I will assume you are doing the same (I have had situations where users have somehow removed C:\Windows\system32 from their path, or managed to get rid of cscript.exe, or it's infected or otherwise doesn't work).

Now copy the file to be copied to the same folder and create a batch file in there with the following lines:

for /f "delims=" %%i in ('^""%~dp0cscript.exe" "%~dp0GetShellFolder.vbs" "Desktop" //nologo^"') DO SET SHELLDIR=%%i
copy /y "%~dp0<file_to_copy>" "%SHELLDIR%\<file_to_copy>"

In the above code you can replace "Desktop" with any valid special folder (Favorites, StartMenu, etc. - the full official list is at https://msdn.microsoft.com/en-us/library/0ea7b5xe%28v=vs.84%29.aspx) and of course <file_to_copy> with the actual file you want placed there. This saves you from trying to access the registry (which you can't do as a limited user anyway) and should be simple enough to adapt to multiple applications.

Oh and for those that don't know the "%~dp0" is just the directory from which the script is being called. It works for UNC paths as well which makes the batch file using it extremely portable. That specifically ends in a trailing "\" though so it can look a little odd at first glance.

There's something I bet you already heard about this! It's called jQuery.

$("#button1").click(function() {
    $("#form1").show();
};

It's really easy and you can use CSS-like selectors and you can add animations. It's really easy to learn.

If you have a background-image, you can do this : Set a rgba() gradient on the background-image.

.img_container {_x000D_
  float: left;_x000D_
  width: 300px;_x000D_
  height: 300px;_x000D_
  display: flex;_x000D_
  justify-content: center;_x000D_
  align-items: center;_x000D_
  border : 1px solid #fff;_x000D_
}_x000D_
_x000D_
.image_original {_x000D_
  background: url(https://i.ibb.co/GkDXWYW/demo-img.jpg);_x000D_
}_x000D_
_x000D_
.image_brighness {_x000D_
  background: linear-gradient(0deg, rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5)), /* the gradient on top, adjust color and opacity to your taste */_x000D_
  url(https://i.ibb.co/GkDXWYW/demo-img.jpg);_x000D_
}_x000D_
_x000D_
.img_container p {_x000D_
  color: #fff;_x000D_
  font-size: 28px;_x000D_
}

<div class="img_container image_original">_x000D_
  <p>normal</p>_x000D_
</div>_x000D_
<div class="img_container image_brighness ">_x000D_
  <p>less brightness</p>_x000D_
</div>

event.target is of type EventTarget which doesn't always have a value. If it's a DOM element you need to cast it to the correct type:

handleChange(event) {
    this.setState({value: (event.target as HTMLInputElement).value});
}

This will infer the "correct" type for the state variable as well though being explicit is probably better

The accepted solution wouldn't work for me as I need a child element with display: inline-block to be both horizontally and vertically centered within a 100% width parent.

I used Flexbox's justify-content and align-items properties, which respectively allow you to center elements horizontally and vertically. By setting both to center on the parent, the child element (or even multiple elements!) will be perfectly in the middle.

This solution does not require fixed width, which would have been unsuitable for me as my button's text will change.

Here is a CodePen demo and a snippet of the relevant code below:

.parent {
  display: flex;
  justify-content: center;
  align-items: center;
}

<div class="parent">
  <a class="child" href="#0">Button</a>
</div>

Read this thread R - boolean operators && and ||.

Basically, the & is vectorized, i.e. it acts on each element of the comparison returning a logical array with the same dimension as the input. && is not, returning a single logical.

Check your controller:

function order()
    $OrderLines = $this->input->post('orderlines');
    $CustomerName = $this->input->post('customer');
    $data = array(
        'OrderLines' => $OrderLines,
        'CustomerName' =>$CustomerName
    ); 

    $this->db->insert('Customer_Orders', $data);
}

It is not a matter of taste. Here are some definitive rules.

If you want to refer to a statically declared variable within the scope in which it was declared then use a C++ reference, and it will be perfectly safe. The same applies to a statically declared smart pointer. Passing parameters by reference is an example of this usage.

If you want to refer to anything from a scope that is wider than the scope in which it is declared then you should use a reference counted smart pointer for it to be perfectly safe.

You can refer to an element of a collection with a reference for syntactic convenience, but it is not safe; the element can be deleted at anytime.

To safely hold a reference to an element of a collection you must use a reference counted smart pointer.

As the other answers say, use g++ instead of gcc.

Or use make: make hi

This worked for me.

        } catch (MessagingException e) {
            throw new RuntimeException(e);
        }
    }

} 

I had similar problem. Following solved it:

Change:

recollect_date TIMESTAMP DEFAULT 'CURRENT_TIMESTAMP',

to:

recollect_date TIMESTAMP DEFAULT CURRENT_TIMESTAMP,

i.e. just remove the quotes around CURRENT_TIMESTAMP.

Hope this helps someone.

Use df.schema.names:

spark.version
# u'2.2.0'

df = spark.createDataFrame([("foo", 1), ("bar", 2)])
df.show()
# +---+---+ 
# | _1| _2|
# +---+---+
# |foo|  1| 
# |bar|  2|
# +---+---+

df.schema.names
# ['_1', '_2']

for i in df.schema.names:
  # df_new = df.withColumn(i, [do-something])
  print i
# _1
# _2

If you need to respond to changes, you can try this:

document.getElementById('select-meal-type').addEventListener('change', function(e) {
    let values = [].slice.call(e.target.selectedOptions).map(a => a.value));
})

The [].slice.call(e.target.selectedOptions) is needed because e.target.selectedOptions returns a HTMLCollection, not an Array. That call converts it to Array so that we can then apply the map function, which extract the values.

As Tyler points out, there's no way to do what you require "directly and reliably", since a given FD may correspond to 0 filenames (in various cases) or > 1 (multiple "hard links" is how the latter situation is generally described). If you do still need the functionality with all the limitations (on speed AND on the possibility of getting 0, 2, ... results rather than 1), here's how you can do it: first, fstat the FD -- this tells you, in the resulting struct stat, what device the file lives on, how many hard links it has, whether it's a special file, etc. This may already answer your question -- e.g. if 0 hard links you will KNOW there is in fact no corresponding filename on disk.

If the stats give you hope, then you have to "walk the tree" of directories on the relevant device until you find all the hard links (or just the first one, if you don't need more than one and any one will do). For that purpose, you use readdir (and opendir &c of course) recursively opening subdirectories until you find in a struct dirent thus received the same inode number you had in the original struct stat (at which time if you want the whole path, rather than just the name, you'll need to walk the chain of directories backwards to reconstruct it).

If this general approach is acceptable, but you need more detailed C code, let us know, it won't be hard to write (though I'd rather not write it if it's useless, i.e. you cannot withstand the inevitably slow performance or the possibility of getting != 1 result for the purposes of your application;-).

Another (silly) possibility is to git commit --amend <<< :wq if you've got vi(m) as $EDITOR.

It's possible if you define such a functional interface with multiple type parameters. There is no such built in type. (There are a few limited types with multiple parameters.)

@FunctionalInterface
interface Function6<One, Two, Three, Four, Five, Six> {
    public Six apply(One one, Two two, Three three, Four four, Five five);
}

public static void main(String[] args) throws Exception {
    Function6<String, Integer, Double, Void, List<Float>, Character> func = (a, b, c, d, e) -> 'z';
}

I've called it Function6 here. The name is at your discretion, just try not to clash with existing names in the Java libraries.

There's also no way to define a variable number of type parameters, if that's what you were asking about.

Some languages, like Scala, define a number of built in such types, with 1, 2, 3, 4, 5, 6, etc. type parameters.

Have a try:

function stop(){_x000D_
    var video = document.getElementById("video");_x000D_
    video.load();_x000D_
}

You want:

DECLARE @times int

SELECT @times =  COUNT(DidWin)
FROM thetable
WHERE DidWin = 1 AND Playername='Me'

You also don't need the 'as' clause.

If you download the 64 bit version of Eclipse; it will look for the 64 bit version of JRE. If you download the 32 bit version of Eclipse; it will look for the 32 bit version of JRE

What I did was to install the both the 32 and 64 bit version of JRE. You can get that from the SUN Oracle site. The JAVA site seems to automatically install the 32 bit version of Java. I guess that's because of the web browser.

I moved implementation to module-level build.gradle from root-level build.gradle. It solves the issue.

You could use Kernel#test:

test ?d, 'some directory'

it gets it's origins from https://ss64.com/bash/test.html you will notice bash test has this flag -d to test if a directory exists -d file True if file is a Directory. [[ -d demofile ]]

Here is the approach I use: http://thaiat.github.io/blog/2014/02/26/angularjs-and-requirejs-for-very-large-applications/

The page shows a possible implementation of AngularJS + RequireJS, where the code is split by features and then component type.

I want to indent a specific section of code in Visual Studio Code:

• Select the lines you want to indent, and
• use Ctrl + ] to indent them.

If you want to format a section (instead of indent it):

• Select the lines you want to format,
• use Ctrl + K, Ctrl + F to format them.

In the latest GitLab Community Edition version 9.2.2.:

1. You have to click on 'Settings' tab located at right most on tabs panel after opening the project.
2. Under 'Settings' you will get section 'Default Branch' dropdown which will give you all branches for the repository. Select the desired branch.
3. Scroll down to hit green colored 'Save changes' button located just after 'Project Avatar'.

Please refer image below:

For very large output logs it could be difficult to open (network delay, scrolling). This is the solution I'm using to check big log files:

    https://${URL}/jenkins/job/${jobName}/${buildNumber}/

in the left column you see: View as plain text. Do a right mouse click on it and choose save links as. Now you can save your big log as .txt file. Open it with notepad++ and you can go through your logs easily without network delays during scrolling.

Convert the JSON string to UTF-8 on your own.

@RequestMapping(value = "/example.json", method = RequestMethod.GET)
@ResponseBody
public byte[] example() throws Exception {

    return "{ 'text': 'äöüß' } ".getBytes("UTF-8");
}

I know this is old but I just had a bear of a time with Razor, could not get it to work no matter how hard I tried. Kept coming back as "undefined" no matter if I used "text" or "html" for attribute. Finally I added "data-value" attribute to the option and it read that just fine.

 <option value="1" data-value="MyText">MyText</option>

 var DisplayText = $(this).find("option:selected").attr("data-value");

Plus useful answers, One of the most powerful point of using Mocks than Subs

If the collaborator [which the main code depend on it] is not under our control (e.g. from a third-party library),
In this case, stub is more difficult to write rather than mock.

Just use itoa to convert to a string, then use atoi to convert back to decimal.

unsigned int_to_int(unsigned int k) {
    char buffer[65]; /* any number higher than sizeof(unsigned int)*bits_per_byte(8) */
    return atoi( itoa(k, buffer, 2) );
}

a way not seen in others

function str_split(str, sep)
    if sep == nil then
        sep = '%s'
    end 

    local res = {}
    local func = function(w)
        table.insert(res, w)
    end 

    string.gsub(str, '[^'..sep..']+', func)
    return res 
end

You can use prop() for this, as Before jQuery 1.6, the .attr() method sometimes took property values into account when retrieving some attributes, which could cause inconsistent behavior. As of jQuery 1.6, the .prop() method provides a way to explicitly retrieve property values, while .attr() retrieves attributes.

var prop=false;
if(value == 1) {
   prop=true; 
}
$('#checkbox').prop('checked',prop);

or simply,

$('#checkbox').prop('checked',(value == 1));

Snippet

$(document).ready(function() {_x000D_
  var chkbox = $('.customcheckbox');_x000D_
  $(".customvalue").keyup(function() {_x000D_
    chkbox.prop('checked', this.value==1);_x000D_
  });_x000D_
});

Using INSERT INTO ... VALUES syntax like in Daniel Vassallo's answer there is one annoying limitation:

From MSDN

The maximum number of rows that can be constructed by inserting rows directly in the VALUES list is 1000

The easiest way to omit this limitation is to use derived table like:

INSERT INTO dbo.Mytable(ID, Name)
SELECT ID, Name 
FROM (
   VALUES (1, 'a'),
          (2, 'b'),
          --...
          -- more than 1000 rows
)sub (ID, Name);

You can compress the bitmap as an byte's array and then uncompress it in another activity, like this.

Compress!!

        ByteArrayOutputStream stream = new ByteArrayOutputStream();
        bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);
        byte[] bytes = stream.toByteArray(); 
        setresult.putExtra("BMP",bytes);

Uncompress!!

        byte[] bytes = data.getByteArrayExtra("BMP");
        Bitmap bmp = BitmapFactory.decodeByteArray(bytes, 0, bytes.length);

import java.util.Scanner;

        int mins=0;
    Scanner sc= new Scanner(System.in);
    System.out.println("Enter the time in mins: ");
        totMins= sc.nextInt();
        hours=(int)(totMins/60);
        mins =(int)(totMins%60);
        System.out.printf("%d:%d",hours,mins);
    }
}

open terminal

\curl -sSL https://get.rvm.io | bash -s stable

restart terminal then

rvm install ruby-2.4.2

check ruby version it should be 2.4.2

According to my interpretation of the implementation of unicode-escape and the unicode repr in the CPython 2.6.5 source, yes; the only difference between repr(unicode_string) and unicode_string.encode('unicode-escape') is the inclusion of wrapping quotes and escaping whichever quote was used.

They are both driven by the same function, unicodeescape_string. This function takes a parameter whose sole function is to toggle the addition of the wrapping quotes and escaping of that quote.

I'm not sure if I am correct, but from the request header that you post:

Request headers

Accept: Application/json

Origin: chrome-extension://hgmloofddffdnphfgcellkdfbfbjeloo

User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/29.0.1547.76 Safari/537.36

Content-Type: application/x-www-form-urlencoded

Accept-Encoding: gzip,deflate,sdch Accept-Language: en-US,en;q=0.8

it seems like you didn't config your request body to JSON type.

Try this

<input onkeypress='return event.charCode >= 48 && _x000D_
                          event.charCode <= 57 || _x000D_
                          event.charCode == 46'>

Here you are. Set source of ImageView statically in xml or dynamically in code.

Shadow is here white.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content" android:layout_height="wrap_content">

    <View android:layout_width="wrap_content" android:layout_height="wrap_content"
        android:background="@android:color/white" android:layout_alignLeft="@+id/image"
        android:layout_alignRight="@id/image" android:layout_alignTop="@id/image"

Try progress from https://pypi.python.org/pypi/progress.

from progress.bar import Bar

bar = Bar('Processing', max=20)
for i in range(20):
    # Do some work
    bar.next()
bar.finish()

The result will be a bar like the following:

Processing |#############                   | 42/100

For special character I normally use the Unicode definition, for the '&' for example: \u0026 if I am correct. Here is a nice reference page: http://jrgraphix.net/research/unicode_blocks.php?block=0

I would suggest:

def foo(element):
    do something
    if not check: return
    do more (because check was succesful)
    do much much more...

Standard Python dictionaries are inherently unordered, so what you're asking to do doesn't really make sense.

If you really, really know what you're doing, use

value_at_index = dic.values()[index]

Bear in mind that adding or removing an element can potentially change the index of every other element.

Add this to your macro and it will recalculate all the cells and formulae.

Call Application.CalculateFullRebuild

Hope it has been already fixed.

PS The above code is for the people looking for a macro to solve the issue.

I had the similar issue. I solved it the following way after a number of attempts to follow the pieces of advice in the forums. I am reposting the solution because it could be helpful for others.

I am running Windows 7 (Apache 2.2 & PHP 5.2.17 & MySQL 5.0.51a), the syntax in the file "httpd.conf" (C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\httpd.conf) was sensitive to slashes. You can check if "php.ini" is read from the right directory. Just type in your browser "localhost/index.php". The code of index.php is the following:

<?php echo phpinfo(); ?>

There is the row (not far from the top) called "Loaded Configuration File". So, if there is nothing added, then the problem could be that your "php.ini" is not read, even you uncommented (extension=php_mysql.dll and extension=php_mysqli.dll). So, in order to make it work I did the following step. I needed to change from

PHPIniDir 'c:\PHP\'

to

PHPIniDir 'c:\PHP'

Pay the attention that the last slash disturbed everything!

Now the row "Loaded Configuration File" gets "C:\PHP\php.ini" after refreshing "localhost/index.php" (before I restarted Apache2.2) as well as mysql block is there. MySQL and PHP are working together!

The answer that worked for me was indeed what OP mentions in his 2015 update: uncheck these two boxes in your Python run config:

• "Add content roots to PYTHONPATH"
• "Add source roots to PYTHONPATH"

I already had the run config set to use the proper venv, so PyCharm doing additional work to add things to the path was not necessary. Instead it was causing errors.

I used with context

//Convert bitmap to drawable
Drawable drawable = new BitmapDrawable(context.getResources(), bitmap);

POST: Use it for creating new resources. It's like INSERT (SQL statement) with an auto-incremented ID. In the response part it contains a new generated Id.

POST is also used for updating a record.

PUT: Use it for creating a new resource, but here I know the identity key. It's like INSERT (SQL statement) where I know in advance the identity key. In the response part it sends nothing.

PUT is also used for updating a resource

The body onLoad could be an alternative too:

<html>
<head><title>Body onLoad Exmaple</title>

<script type="text/javascript">
    function window_onload() {
        //do something
    }
</script>

</head>
<body onLoad="window_onload()">

</body>
</html>

From this excellent article on query locks in Postgres, one can get blocked query and blocker query and their information from the following query.

CREATE VIEW lock_monitor AS(
SELECT
  COALESCE(blockingl.relation::regclass::text,blockingl.locktype) as locked_item,
  now() - blockeda.query_start AS waiting_duration, blockeda.pid AS blocked_pid,
  blockeda.query as blocked_query, blockedl.mode as blocked_mode,
  blockinga.pid AS blocking_pid, blockinga.query as blocking_query,
  blockingl.mode as blocking_mode
FROM pg_catalog.pg_locks blockedl
JOIN pg_stat_activity blockeda ON blockedl.pid = blockeda.pid
JOIN pg_catalog.pg_locks blockingl ON(
  ( (blockingl.transactionid=blockedl.transactionid) OR
  (blockingl.relation=blockedl.relation AND blockingl.locktype=blockedl.locktype)
  ) AND blockedl.pid != blockingl.pid)
JOIN pg_stat_activity blockinga ON blockingl.pid = blockinga.pid
  AND blockinga.datid = blockeda.datid
WHERE NOT blockedl.granted
AND blockinga.datname = current_database()
);

SELECT * from lock_monitor;

As the query is long but useful, the article author has created a view for it to simplify it's usage.

You can add values to the HttpWebRequest.Headers collection.

According to MSDN, it should be supported in windows phone: http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.headers%28v=vs.95%29.aspx

This should do it:

sed -e s/deletethis//g -i *
sed -e "s/deletethis//g" -i.backup *
sed -e "s/deletethis//g" -i .backup *

it will replace all occurrences of "deletethis" with "" (nothing) in all files (*), editing them in place.

In the second form the pattern can be edited a little safer, and it makes backups of any modified files, by suffixing them with ".backup".

The third form is the way some versions of sed like it. (e.g. Mac OS X)

man sed for more information.

Try the format syntax:

print ("{0}. {1} appears {2} times.".format(1, 'b', 3.1415))

Outputs:

1. b appears 3.1415 times.

The print function is called just like any other function, with parenthesis around all its arguments.

Pandas has the itertuples method to do exactly this:

list(df[['lat', 'long']].itertuples(index=False, name=None))

If you use androidX instead of android, you need change

to

and change

<android.support.constraint.ConstraintLayout>

to

<androidx.constraintlayout.widget.ConstraintLayout>

It's certainly possible to grab a screenshot using the .NET Framework. The simplest way is to create a new Bitmap object and draw into that using the Graphics.CopyFromScreen method.

Sample code:

using (Bitmap bmpScreenCapture = new Bitmap(Screen.PrimaryScreen.Bounds.Width, 
                                            Screen.PrimaryScreen.Bounds.Height))
using (Graphics g = Graphics.FromImage(bmpScreenCapture))
{
    g.CopyFromScreen(Screen.PrimaryScreen.Bounds.X,
                     Screen.PrimaryScreen.Bounds.Y,
                     0, 0,
                     bmpScreenCapture.Size,
                     CopyPixelOperation.SourceCopy);
}

Caveat: This method doesn't work properly for layered windows. Hans Passant's answer here explains the more complicated method required to get those in your screen shots.

You just can't be sure on a Unix system, that a .txt file truly is a text file. Your best bet is to use "file". Maybe try using:

file -ib "$file"

Then you can use a list of MIME types to match against or parse the first part of the MIME where you get stuff like "text", "application", etc.

=(B0+4)/($A$0)

Although most answers are suggesting RESEED to 0, and while some see this as a flaw for TRUNCATED tables, Microsoft has a solution that excludes the ID

DBCC CHECKIDENT ('[TestTable]', RESEED)

This will check the table and reset to the next ID. This has been available since MS SQL 2005 to current.

https://msdn.microsoft.com/en-us/library/ms176057.aspx

I think I'd do it as simply as:

public static int safeLongToInt(long l) {
    if (l < Integer.MIN_VALUE || l > Integer.MAX_VALUE) {
        throw new IllegalArgumentException
            (l + " cannot be cast to int without changing its value.");
    }
    return (int) l;
}

I think that expresses the intent more clearly than the repeated casting... but it's somewhat subjective.

Note of potential interest - in C# it would just be:

return checked ((int) l);

Use:

implode('-', array_reverse(explode('-', $date)));

Without the date conversion overhead, I am not sure it'll matter much.

#The Best way is to use `fStrings` (very easy and powerful in python3)   
#Format: f'your-string'   
#For Example:

mylist=['laks',444,'M']

cursor.execute(f'INSERT INTO mytable VALUES ("{mylist[0]}","{mylist[1]}","{mylist[2]}")')

#THATS ALL!! EASY!!
#You can use it with for loop!

<a href="#" onclick="window.open('MyPDF.pdf', '_blank', 'fullscreen=yes'); return false;">MyPDF</a>

The above link will open the PDF in full screen mode, that's the best you can achieve.

For MultiIndex you can extract its subindex using

df['si_name'] = R.index.get_level_values('si_name') 

where si_name is the name of the subindex.

Do this:

$checksum = "my value"; 
header("Location: recordupdated.php?checksum=$checksum");

This is actually pretty easy to fix and doesn't take any coding:

1.Click on the Plots tab above the console. 2.Then at the top right corner of the plots screen click on the options button. 3.Lastly uncheck the "Mute inline plotting" button

Now re-run your script and your graphs should show up in the console.

Cheers.

I too had faced this issue.The below exception used to come

java.sql.SQLException: - ORA-01000: maximum open cursors exceeded

I was using Spring Framework with Spring JDBC for dao layer.

My application used to leak cursors somehow and after few minutes or so, It used to give me this exception.

After a lot of thorough debugging and analysis, I found that there was the problem with the Indexing, Primary Key and Unique Constraints in one of the Table being used in the Query i was executing.

My application was trying to update the Columns which were mistakenly Indexed. So, whenever my application was hitting the update query on the indexed columns, The database was trying to do the reindexing based on the updated values. It was leaking the cursors.

I was able to solve the problem by doing Proper Indexing on the columns which were used to search in the query and applying appropriate constraints wherever required.

The main problem here is that it ignores all and any error: Out of memory, CPU is burning, user wants to stop, program wants to exit, Jabberwocky is killing users.

This is way too much. In your head, you're thinking "I want to ignore this network error". If something unexpected goes wrong, then your code silently continues and breaks in completely unpredictable ways that no one can debug.

That's why you should limit yourself to ignoring specifically only some errors and let the rest pass.

In PLSQL block, columns of select statements must be assigned to variables, which is not the case in SQL statements.

The second BEGIN's SQL statement doesn't have INTO clause and that caused the error.

An alternative to GETDATE() is CURRENT_TIMESTAMP. Does the exact same thing.

Same solution as @Al3x for Windows x64, in cmd.exe:

cd %programfiles%\Oracle\VirtualBox

VBoxManage internalcommands sethduuid "full/path/to/.vdi"

This randomizes the UUID of the disk. Pro tip: Right click the .vdi file while holding shift and select "Copy as path" to obtain "full/path/to/.vdi" and enable quick edit in cmd.exe, then right click to paste.

You can easily verify your instance is an array or not by the following function.

func verifyIsObjectOfAnArray<T>(_ object: T) -> Bool {
   if let _ = object as? [T] {
      return true
   }

   return false
}

Even you can access it as follows. You will receive nil if the object wouldn't be an array.

func verifyIsObjectOfAnArray<T>(_ object: T) -> [T]? {
   if let array = object as? [T] {
      return array
   }

   return nil
}

I've tried to create a utils class for this, so any activity or fragment can implement this to be simpler.

The code was written with Kotlin & has Java-interop as well.

I'm using coroutine to delay and reset the flag variable. But you can modify it to your needs.

Additional files: SafeToast.kt

lateinit var toast: Toast

fun Context.safeToast(msg: String, length: Int = Toast.LENGTH_LONG, action: (Context) -> Toast = default) {
    toast = SafeToast.makeText(this@safeToast, msg, length).apply {
        // do anything new here
        action(this@safeToast)
        show()
    }
}

fun Context.toastSpammable(msg: String) {
    cancel()
    safeToast(msg, Toast.LENGTH_SHORT)
}

fun Fragment.toastSpammable(msg: String) {
    cancel()
    requireContext().safeToast(msg, Toast.LENGTH_SHORT)
}

private val default: (Context) -> Toast = { it -> SafeToast.makeText(it, "", Toast.LENGTH_LONG) }

private fun cancel() {
    if (::toast.isInitialized) toast.cancel()
}

import kotlinx.coroutines.launch


private var backButtonPressedTwice = false

fun Activity.onBackPressedTwiceFinish() {
    onBackPressedTwiceFinish(getString(R.string.msg_back_pressed_to_exit), 2000)
}

fun Activity.onBackPressedTwiceFinish(@StringRes message: Int, time: Long) {
    onBackPressedTwiceFinish(getString(message), time)
}

fun Activity.onBackPressedTwiceFinish(message: String, time: Long) {
    if (backButtonPressedTwice) {
        onBackPressed()
    } else {
        backButtonPressedTwice = true
        toastSpammable(message)
        GlobalScope.launch {
            delay(time)
            backButtonPressedTwice = false
        }
    }
}

Usage in Kotlin

// ActivityA.kt
override fun onBackPressed() {
    onBackPressedTwiceFinish()
}

Usage in Java

@Override 
public void onBackPressed() {
    ActivityUtils.onBackPressedTwiceFinish()
}

oltp- mostly used for business transaction.used to collect business data.In sql we use insert,update and delete command for retrieving small source of data.like wise they are highly normalised.... OLTP Mostly used for maintaining the data integrity.

olap- mostly use for reporting,data mining and business analytic purpose. for the large or bulk data.deliberately it is de-normalised. it stores Historical data..

No, but you can install an isolated Python build (such as ActivePython) under your $HOME directory.

This approach is the fastest, and doesn't require you to compile Python yourself.

(as a bonus, you also get to use ActiveState's binary package manager)

I found the file located at:

C:\xampp\php\php.ini

Uncommented:

;extension=php_curl.dll

I tried the below code,

    function executeQuery() {
  $.ajax({
    url: 'url/path/here',
    success: function(data) {
      // do something with the return value here if you like
    }
  });
  setTimeout(executeQuery, 5000); // you could choose not to continue on failure...
}

$(document).ready(function() {
  // run the first time; all subsequent calls will take care of themselves
  setTimeout(executeQuery, 5000);
});

This didn't work as expected for the specified interval,the page didn't load completely and the function was been called continuously. Its better to call setTimeout(executeQuery, 5000); outside executeQuery() in a separate function as below,

function executeQuery() {
  $.ajax({
    url: 'url/path/here',
    success: function(data) {
      // do something with the return value here if you like
    }
  });
  updateCall();
}

function updateCall(){
setTimeout(function(){executeQuery()}, 5000);
}

$(document).ready(function() {
  executeQuery();
});

This worked exactly as intended.

If you want the current date as String, try this:

DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Date date = new Date();
System.out.println(dateFormat.format(date));

or

DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss");
Calendar cal = Calendar.getInstance();
System.out.println(dateFormat.format(cal.getTime()));

http://www.mkyong.com/java/java-how-to-get-current-date-time-date-and-calender/

By default . (any character) does not match newline characters.

This means you can simply match zero or more of any character then append the end tag.

Find: <li><a href="#">.* Replace: $0</a>

I find "per container per bean" difficult to apprehend. I would say "one bean per bean id in a container".Lets have an example to understand it. We have a bean class Sample. I have defined two beans from this class in bean definition, like:

<bean id="id1" class="com.example.Sample" scope="singleton">
        <property name="name" value="James Bond 001"/>    
</bean>    
<bean id="id7" class="com.example.Sample" scope="singleton">
        <property name="name" value="James Bond 007"/>    
</bean>

So when ever I try to get the bean with id "id1",the spring container will create one bean, cache it and return same bean where ever refered with id1. If I try to get it with id7, another bean will be created from Sample class, same will be cached and returned each time you referred that with id7.

This is unlikely with Singleton pattern. In Singlton pattern one object per class loader is created always. However in Spring, making the scope as Singleton does not restrict the container from creating many instances from that class. It just restricts new object creation for the same ID again, returning previously created object when an object is requested for the same id. Reference

A .zip file is required in order to include npm modules in Lambda. And you really shouldn't be using the Lambda web editor for much of anything- as with any production code, you should be developing locally, committing to git, etc.

MY FLOW:

1) My Lambda functions are usually helper utilities for a larger project, so I create a /aws/lambdas directory within that to house them.

2) Each individual lambda directory contains an index.js file containing the function code, a package.json file defining dependencies, and a /node_modules subdirectory. (The package.json file is not used by Lambda, it's just so we can locally run the npm install command.)

package.json:

{
  "name": "my_lambda",
  "dependencies": {
    "svg2png": "^4.1.1"
  }
}

3) I .gitignore all node_modules directories and .zip files so that the files generated from npm installs and zipping won't clutter our repo.

.gitignore:

# Ignore node_modules
**/node_modules

# Ignore any zip files
*.zip

4) I run npm install from within the directory to install modules, and develop/test the function locally.

5) I .zip the lambda directory and upload it via the console.

(IMPORTANT: Do not use Mac's 'compress' utility from Finder to zip the file! You must run zip from the CLI from within the root of the directory- see here)

zip -r ../yourfilename.zip * 

NOTE:

You might run into problems if you install the node modules locally on your Mac, as some platform-specific modules may fail when deployed to Lambda's Linux-based environment. (See https://stackoverflow.com/a/29994851/165673)

The solution is to compile the modules on an EC2 instance launched from the AMI that corresponds with the Lambda Node.js runtime you're using (See this list of Lambda runtimes and their respective AMIs).

The wikipedia article on r-squareds suggests that it may be used for general model fitting rather than just linear regression.

I want to add something. Actually, Task.Delay is a timer based wait mechanism. If you look at the source you would find a reference to a Timer class which is responsible for the delay. On the other hand Thread.Sleep actually makes current thread to sleep, that way you are just blocking and wasting one thread. In async programming model you should always use Task.Delay() if you want something(continuation) happen after some delay.

Try the zsh. It supports suffix alias, so you can define X in your .zshrc to be

alias -g X="| cut -d' ' -f2"

then you can do:

cat file X

You can take it one step further and define it for the nth column:

alias -g X2="| cut -d' ' -f2"
alias -g X1="| cut -d' ' -f1"
alias -g X3="| cut -d' ' -f3"

which will output the nth column of file "file". You can do this for grep output or less output, too. This is very handy and a killer feature of the zsh.

You can go one step further and define D to be:

alias -g D="|xargs rm"

Now you can type:

cat file X1 D

to delete all files mentioned in the first column of file "file".

If you know the bash, the zsh is not much of a change except for some new features.

The Project Facet->Java should match whatever you have in the pom.xml for the maven-compiler-plugin artifact source and target.This is perfect.But if you donot have it here then you can also fix it by matching Java compiler version in Porject-Facets from the setting: Eclispe->Preferences->Java->Compiler

Sometime it is fixed by the Padding .. if you can play with that, then, it should fix your problem

<style type=text/css>

YourbuttonByID {Padding: 20px 80px; "for example" padding-left:50px; 
 padding-right:30px "to fix the text in the middle 
 without interfering with the text itself"}

</style>

It worked for me

Just my couple cents... sometimes it's good to be sure there are no any duplicates... so we have the next function in the utils library:

jQuery.loadCSS = function(url) {
    if (!$('link[href="' + url + '"]').length)
        $('head').append('<link rel="stylesheet" type="text/css" href="' + url + '">');
}

How to use:

$.loadCSS('css/style2.css');

I had the same issue.. and you don't need to add a physical column.. cuz now you will have to maintain it.. what you can do is add a generic column in the select query:

EX:

select tb1.col1, tb1.col2, tb1.col3 ,
( 
select 'Match' from table2 as tbl2
where tbl1.col1 = tbl2.col1 and tab1.col2 = tbl2.col2
)  
from myTable as tbl1

Use this PHP script:

 $version = apache_get_version();
    echo "$version\n";

Se apache_get_version.

Logical layers are merely a way of organizing your code. Typical layers include Presentation, Business and Data – the same as the traditional 3-tier model. But when we’re talking about layers, we’re only talking about logical organization of code. In no way is it implied that these layers might run on different computers or in different processes on a single computer or even in a single process on a single computer. All we are doing is discussing a way of organizing a code into a set of layers defined by specific function.

Physical tiers however, are only about where the code runs. Specifically, tiers are places where layers are deployed and where layers run. In other words, tiers are the physical deployment of layers.

Use StringIO to turn the read string into a file-like object:

A unit test should have no dependencies on code outside the unit tested. You decide what the unit is by looking for the smallest testable part. Where there are dependencies they should be replaced by false objects. Mocks, stubs .. The tests execution thread starts and ends within the smallest testable unit.

When false objects are replaced by real objects and tests execution thread crosses into other testable units, you have an integration test

Here, Apple Documentation has explained the difference between weak and strong property using various examples :

Here, In this blog author has collected all the properties in same place. It will help to compare properties characteristics :

http://rdcworld-iphone.blogspot.in/2012/12/variable-property-attributes-or.html

According to http://blog.flameeyes.eu/2008/04/14/what-about-those-la-files, they're needed to handle dependencies. But using pkg-config may be a better option:

In a perfect world, every static library needing dependencies would have its own .pc file for pkg-config, and every package trying to statically link to that library would be using pkg-config --static to get the libraries to link to.

$('#myCheckbox').change(function () {
    if ($(this).prop("checked")) {
        // checked
        return;
    }
    // not checked
});

Note: In older versions of jquery it was OK to use attr. Now it's suggested to use prop to read the state.

Try this

string stringToCheck = "text1text2text3";
string[] stringArray = new string[] { "text1" };

var t = lines.ToList().Find(c => c.Contains(stringToCheck));

It will return you the line with the first incidence of the text that you are looking for.

I guess ch is a declared as char. Since char is a primitive data type and not and object, you can't call any methof from it. You should use Character.isLetter(ch).
