Use the system function.

system("myfile.sh"); // myfile.sh should be chmod +x

This is my Python function:

def add_nulls(num, cnt=2):
  cnt = cnt - len(str(num))
  nulls = '0' * cnt
  return '%s%s' % (nulls, num)

I modified rushidesai1's answer to include a working example.

You can use ORDER BY clause to sort data rows by values in columns. Something like

=QUERY(responses!A1:K; "Select C, D, E where B contains '2nd Web Design' Order By C, D")

If you’d like to order by some columns descending, others ascending, you can add desc/asc, ie:

=QUERY(responses!A1:K; "Select C, D, E where B contains '2nd Web Design' Order By C desc, D")

To create an empty vector use:

vec <- c();

Please note, I am not making any assumptions about the type of vector you require, e.g. numeric.

Once the vector has been created you can add elements to it as follows:

For example, to add the numeric value 1:

vec <- c(vec, 1);

or, to add a string value "a"

vec <- c(vec, "a");

This can be caused when Python interpreter can't find your code. You have to mention explicitly to Python to find your code in this location.

To do so:

• Go to your python console
• Add sys.path.extend(['your module location']) to Python console.

In your case:

• Go to your python console,

• On the start, write the following code:

  import sys
  sys.path.extend([my module URI location])
  

• Once you have written this statement you can run following command:

  from mymodule import functions
  

jdk.tools:jdk.tools (or com.sun:tools, or whatever you name it) is a JAR file that is distributed with JDK. Usually you add it to maven projects like this:

<dependency>
    <groupId>jdk.tools</groupId>
    <artifactId>jdk.tools</artifactId>
    <scope>system</scope>
    <systemPath>${java.home}/../lib/tools.jar</systemPath>
</dependency>

See, the Maven FAQ for adding dependencies to tools.jar

Or, you can manually install tools.jar in the local repository using:

mvn install:install-file -DgroupId=jdk.tools -DartifactId=jdk.tools -Dpackaging=jar -Dversion=1.6 -Dfile=tools.jar -DgeneratePom=true

and then reference it like Cloudera did, using:

<dependency>
    <groupId>jdk.tools</groupId>
    <artifactId>jdk.tools</artifactId>
    <version>1.6</version>
</dependency>

This error occurs because VMware has a bug that uses the absolute path of the disk file in certain situations.

If you look at the top of that small *.vmdk file you'll likely see an incorrect absolute path to the original VMDK file that needs to be corrected.

Use eval:

x="ls | wc"
eval "$x"
y=$(eval "$x")
echo "$y"

Fully fleshed out example with arrows for only the red edges:

val_map = {'A': 1.0,
           'D': 0.5714285714285714,
           'H': 0.0}

values = [val_map.get(node, 0.25) for node in G.nodes()]

# Specify the edges you want here
red_edges = [('A', 'C'), ('E', 'C')]
edge_colours = ['black' if not edge in red_edges else 'red'
                for edge in G.edges()]
black_edges = [edge for edge in G.edges() if edge not in red_edges]

# Need to create a layout when doing
# separate calls to draw nodes and edges
pos = nx.spring_layout(G)
nx.draw_networkx_nodes(G, pos, cmap=plt.get_cmap('jet'), 
                       node_color = values, node_size = 500)
nx.draw_networkx_labels(G, pos)

On a Mac, I found the output contained the information I was looking for:

After adding /usr/local/share/npm/bin to the export PATH line in my .bash_profile, saving it, and sourceing it, I was able to run

$> karma --help

normally.

Here is something i just put together.

In addition to the comments above, I have the following additional comments:

• Do not mix Attachments and AlternativeView, use one or the other. If you mix them, the inline attachments will be rendered as unknown downloads.
• While Outlook and Google allow standard HTML-style "cid:att-001" this does NOT work on iPhone (late 2016 patch level), rather use pure alpha numeric "cid:att-001" -> "cid:att001"

As an aside: Outlook (even Office 2015) rendering (still the clear majority for business users) requires the use of TABLE TR TD style HTML, as it does not fully support the HTML box model.

Dynamic linking (.so) can be much much faster than static linking (.a). Especially when you have a slow network drive. This is since you have all of the code in the .a file which needs to be processed and written out. In addition, a much larger executable file needs to be written out to the disk.

This is kind of a stupid mistake to make, but having an extra comma at the end of the field declaration line in the model class, makes the line have no effect.

It happens when you copy paste the def. from the migration, which itself is defined as an array.

Though maybe this would help someone :-)

The second most upvoted answer here is on the closest track possible to a one-liner jQuery method of the intended behavior the OP wants, but they stumbled at the end of their code, and it has a flaw. If your item to be removed isn't actually in the array, the last item will get removed.

A few have noticed this issue, and some have offered ways to loop through to guard against this. I offer the shortest, cleanest method I could find, and I have commented under their answer for the way to fix their code according to this method.

var x = [1, 2, "bye", 3, 4];
var y = [1, 2, 3, 4];
var removeItem = "bye";

// Removing an item that exists in array
x.splice( $.inArray(removeItem,x), $.inArray(removeItem,x) ); // This is the one-liner used

// Removing an item that DOESN'T exist in array
y.splice( $.inArray(removeItem,y), $.inArray(removeItem,y) ); // Same usage, different array

// OUTPUT -- both cases are expected to be [1,2,3,4]
alert(x + '\n' + y);

array x will remove the element "bye" easily, and array y will be untouched.

The use of the argument $.inArray(removeItem,array) as a second argument actually ends up being the length to splice. Since the item was not found, this evaluates to array.splice(-1,-1);, which will just result in nothing being spliced... all without having to write a loop for this.

You can create your own extension method to do this:

public static bool Contains(this string source, string toCheck, StringComparison comp)
  {
    return source != null && toCheck != null && source.IndexOf(toCheck, comp) >= 0;
  }

And then call:

 mystring.Contains(myStringToCheck, StringComparison.OrdinalIgnoreCase);

substr(i,j) means that you start from the index i (assuming the first index to be 0) and take next j chars. It does not mean going up to the index j.

I had this problem with a third party code. Someone forgot to set the super inside of viewWillAppear and viewWillDisappear in a custom TabBarController class.

- (void) viewWillAppear:(BOOL)animated {

    [super viewWillAppear:animated];
    // code...
}

or

- (void) viewWillDisappear:(BOOL)animated {

    [super viewWillDisappear:animated];
    // code...
}

Don't use while True and break statements. It's bad programming.

Imagine you come to debug someone else's code and you see a while True on line 1 and then have to trawl your way through another 200 lines of code with 15 break statements in it, having to read umpteen lines of code for each one to work out what actually causes it to get to the break. You'd want to kill them...a lot.

The condition that causes a while loop to stop iterating should always be clear from the while loop line of code itself without having to look elsewhere.

Phil has the "correct" solution, as it has a clear end condition right there in the while loop statement itself.

You certainly can. Others have pointed out correctly that you need to do i += 3. You can't do what you have posted because all you are doing here is adding i + 3 but never assigning the result back to i. i++ is just a shorthand for i = i + 1, similarly i +=3 is a shorthand for i = i + 3.

Use this example :

<button name="nameButton" id="idButton" title="your title" class="btn btn-secondary" onclick="location.href='@Url.Action( "Index","Controller" new {  id = Item.id })';return false;">valueButton</button>

Microsoft .NET framework 3.5 can be installed on windows 10 without having installation media. The file you need is called microsoft-windows-netfx3-ondemand-package.cab. Just google it and you will get the download links. After downloading it, copy that file to C:\dotnet35 and run the following command.

Dism.exe /online /enable-feature /featurename:NetFX3 /All /Source:c:\dotnet35 /LimitAccess

Tested and worked in Windows 10 without any issue.

This is how you can do it from DB2 client.

1. Open the Command Editor and Run the select Query in the Commands Tab.

2. Open the corresponding Query Results Tab

3. Then from Menu --> Selected --> Export

Depending on if your regex flavor supports it, I might use:

\b[A-Z]{2}\d{6}\b    # Ensure there are "word boundaries" on either side, or

(?<![A-Z])[A-Z]{2}\d{6}(?!\d) # Ensure there isn't a uppercase letter before
                              # and that there is not a digit after

Jefferson is right, you have to do it backwards.

Here's the c# equivalent:

for (var i == list.Items.Count - 1; i >= 0; i--)
{
    list.Items.RemoveAt(i);
}

I had to overcome this problem myself, when debugging web applications. -v is great, but a little too verbose for my tastes. This is the (bash-only) solution I came up with:

curl -v http://example.com/ 2> >(sed '/^*/d')

This works because the output from -v is sent to stderr, not stdout. By redirecting this to a subshell, we can sed it to remove lines that start with *. Since the real output does not pass through the subshell, it is not affected. Using a subshell is a little heavy-handed, but it's the easiest way to redirect stderr to another command. (As I noted, I'm only using this for testing, so it works fine for me.)

Most of the answers above describe very nicely how contents are being served. What I was looking as additional was listing of the directory so that other contents of the directory can be browsed. Here is my solution for further readers:

'use strict';

var finalhandler = require('finalhandler');
var http = require('http');
var serveIndex = require('serve-index');
var serveStatic = require('serve-static');
var appRootDir = require('app-root-dir').get();
var log = require(appRootDir + '/log/bunyan.js');

var PORT = process.env.port || 8097;

// Serve directory indexes for reports folder (with icons)
var index = serveIndex('reports/', {'icons': true});

// Serve up files under the folder
var serve = serveStatic('reports/');

// Create server
var server = http.createServer(function onRequest(req, res){
    var done = finalhandler(req, res);
    serve(req, res, function onNext(err) {
    if (err)
        return done(err);
    index(req, res, done);
    })
});


server.listen(PORT, log.info('Server listening on: ', PORT));

In Response to Janusz original question, there are several ways to achieve this all of which vary in their difficulty level and have been stated below. Using a web view is good, but it is very limited in terms of look and feel and controllability. If you are drawing a bitmap from a canvas, the most versatile solutions that have been proposed seems to be MikeOrtiz's, Robert Foss's and/or what Jacob Nordfalk suggested. There is a great example for incorporating the android-multitouch-controller by PaulBourke, and is great for having the multi-touch support and alltypes of custom views.

Personally, if you are simply drawing a canvas to a bitmap and then displaying it inside and ImageView and want to be able to zoom into and move around using multi touch, I find MikeOrtiz's solution as the easiest. However, for my purposes the code from the Git that he has provided seems to only work when his TouchImageView custom ImageView class is the only child or provide the layout params as:

android:layout_height="match_parent"
android:layout_height="match_parent"

Unfortunately due to my layout design, I needed "wrap_content" for "layout_height". When I changed it to this the image was cropped at the bottom and I couldn't scroll or zoom to the cropped region. So I took a look at the Source for ImageView just to see how Android implemented "onMeasure" and changed MikeOrtiz's to suit.

   @Override
protected void onMeasure (int widthMeasureSpec, int heightMeasureSpec)
{
    super.onMeasure(widthMeasureSpec, heightMeasureSpec);

  //**** ADDED THIS ********/////
      int  w = (int) bmWidth;
      int  h = (int) bmHeight;
     width = resolveSize(w, widthMeasureSpec);  
     height = resolveSize(h, heightMeasureSpec);
  //**** END ********///   

   // width = MeasureSpec.getSize(widthMeasureSpec);   // REMOVED
   // height = MeasureSpec.getSize(heightMeasureSpec); // REMOVED

    //Fit to screen.
    float scale;
    float scaleX =  (float)width / (float)bmWidth;
    float scaleY = (float)height / (float)bmHeight;

    scale = Math.min(scaleX, scaleY);
    matrix.setScale(scale, scale);
    setImageMatrix(matrix);
    saveScale = 1f;

    // Center the image
    redundantYSpace = (float)height - (scale * (float)bmHeight) ;
    redundantXSpace = (float)width - (scale * (float)bmWidth);
    redundantYSpace /= (float)2;
    redundantXSpace /= (float)2;

    matrix.postTranslate(redundantXSpace, redundantYSpace);

    origWidth = width - 2 * redundantXSpace;
    origHeight = height - 2 * redundantYSpace;
   // origHeight = bmHeight;
    right = width * saveScale - width - (2 * redundantXSpace * saveScale);
    bottom = height * saveScale - height - (2 * redundantYSpace * saveScale);

    setImageMatrix(matrix);
}

Here resolveSize(int,int) is a "Utility to reconcile a desired size with constraints imposed by a MeasureSpec, where :

Parameters:

 - size How big the view wants to be
 - MeasureSpec Constraints imposed by the parent

Returns:

 - The size this view should be."

So essentially providing a behaviour a little more similar to the original ImageView class when the image is loaded. Some more changes could be made to support a greater variety of screens which modify the aspect ratio. But for now I Hope this helps. Thanks to MikeOrtiz for his original code, great work.

jeues answer helped me nothing :-( after hours I finally found the solution for my system and I think this will help other people too. I had to set the LD_LIBRARY_PATH like this:

   export LD_LIBRARY_PATH=/usr/lib/x86_64-linux-gnu/

after that everything worked very well, even without any "-extension RANDR" switch.

Have a look at the WebRequestHandler Class and its ServerCertificateValidationCallback Property:

using (var handler = new WebRequestHandler())
{
    handler.ServerCertificateValidationCallback = ...

    using (var client = new HttpClient(handler))
    {
        ...
    }
}

This error occurs only due to the difference in version. Whenever this kinda error occurs try to change the SDK versions, Gradle Build versions, or dependency version. If you are using

targetSdkVersion = 26
compileSdkVersion = 26
'com.android.tools.build:gradle:3.6.3'

then add this version for firebase dependencies.

implementation 'com.google.firebase:firebase-core:11.6.0'
implementation 'com.google.firebase:firebase-database:11.6.0'
implementation 'com.google.firebase:firebase-auth:11.6.0'

It works.

Inside the function parameter list, char arr[] is absolutely equivalent to char *arr, so the pair of definitions and the pair of declarations are equivalent.

void function(char arr[]) { ... }
void function(char *arr)  { ... }

void function(char arr[]);
void function(char *arr);

The issue is the calling context. You provided a string literal to the function; string literals may not be modified; your function attempted to modify the string literal it was given; your program invoked undefined behaviour and crashed. All completely kosher.

Treat string literals as if they were static const char literal[] = "string literal"; and do not attempt to modify them.

Installing XCode requires:

• Enrolling on the Apple website (not fun)
• Downloading a 4.7G installer

To install g++ *WITHOUT* having to download the MASSIVE 4.7G xCode install, try this package:

https://github.com/kennethreitz/osx-gcc-installer

The DMG files linked on that page are ~270M and much quicker to install. This was perfect for me, getting homebrew up and running with a minimum of hassle.

The github project itself is basically a script that repackages just the critical chunks of xCode for distribution. In order to run that script and build the DMG files, you'd need to already have an XCode install, which would kind of defeat the point, so the pre-built DMG files are hosted on the project page.

In python 3.7 and above there is a new and easy way. here is the syntax:

name = "Eric"
age = 74
f"Hello, {name}. You are {age}."

OutPut:

Hello, Eric. You are 74.

A convenient function for saving plots is ggsave(), which can automatically guess the device type based on the file extension, and smooths over differences between devices. You save with a certain size and units like this:

ggsave("mtcars.png", width = 20, height = 20, units = "cm")

In R markdown, figure size can be specified by chunk:

```{r, fig.width=6, fig.height=4}  
plot(1:5)
```

there is a Gradle plugin that download/bootstraps a JDK automatically:

https://plugins.gradle.org/plugin/com.github.rmee.jdk-bootstrap

No IDE integration yet and a decent shell required on Windows.

Just a comment on this - I've used HTML5 video for a full-screen background and it works a treat - but make sure to use either Height:100% and width:auto or the other way around - to ensure you keep aspect ratio.

As for Ipads -you can (apparently) do this, by having a hidden and then forcing the click event to fire, and having the function of the click event kick off the Load/Play().

P.s - this shouldn't require any plugins and can be done with minimal JS - If you're targeting any mobile device (I would assume you might be..) staying away from any such framework is the way forward.

Singletons aren't evil, if you use it properly & minimally. There are lot of other good design patterns which replaces the needs of singleton at some point (& also gives best results). But some programmers are unaware of those good patterns & uses the singleton for all the cases which makes the singleton evil for them.

Modulo would be the correct answer, but if you're doing it manually this should work.

num = input("Enter a number: ")
div = input("Enter a divisor: ")

while num >= div:
    num -= div
print num

Linq to Sql.

Sql server will cache the query plans, so there's no performance gain for sprocs.

Your linq statements, on the other hand, will be logically part of and tested with your application. Sprocs are always a bit separated and are harder to maintain and test.

If I was working on a new application from scratch right now I would just use Linq, no sprocs.

public void onPressed(Button button, int drawable) {
            if (!isPressed) {

please try this, in this code i m trying to change the background of button on button click this works fine.

You can also do

subset(df, aged <= laclen)

In my case I had Identity="ApplicationPoolIdentity" for my IIS Application Pool.

After I added IIS APPPOOL\ApplicationName user to SQL Server it works.

This should do the trick:

image = open("image.png", "wb")
image.write(base64string.decode('base64'))
image.close()

I've passed parent pid using environment to the child, then periodically checked if /proc/$ppid exists from the child.

You can write your own extension method

public static class IntegerExtensions
{
    public static int ParseInt(this string value, int defaultValue = 0)
    {
        int parsedValue;
        if (int.TryParse(value, out parsedValue))
        {
            return parsedValue;
        }

        return defaultValue;
    }

    public static int? ParseNullableInt(this string value)
    {
        if (string.IsNullOrEmpty(value))
        {
            return null;
        }

        return value.ParseInt();
    }
}

And wherever in code just call

int myNumber = someString.ParseInt(); // Returns value or 0
int age = someString.ParseInt(18); // With default value 18
int? userId = someString.ParseNullableInt(); // Returns value or null

In this concrete case

int yourValue = TextBoxD1.Text.ParseInt();

You must use OpenSSL and keytool.

OpenSSL for CER & PVK file > P12

openssl pkcs12 -export -name servercert -in selfsignedcert.crt -inkey serverprivatekey.key -out myp12keystore.p12

Keytool for p12 > JKS

keytool -importkeystore -destkeystore mykeystore.jks -srckeystore myp12keystore.p12 -srcstoretype pkcs12 -alias servercert

You can use fingerprintjs2

new Fingerprint2().get(function(result, components) {
  console.log(result) // a hash, representing your device fingerprint
  console.log(components) // an array of FP components
  //submit hash and JSON object to the server 
})

After that you can check all your users against existing and check JSON similarity, so even if their fingerprint mutates, you still can track them

If each line is a fixed length then you can open a Stream around it, seek (bytes per line) * n into the file and read your line from there.

using( Stream stream = File.Open(fileName, FileMode.Open) )
{
    stream.Seek(bytesPerLine * (myLine - 1), SeekOrigin.Begin);
    using( StreamReader reader = new StreamReader(stream) )
    {
        string line = reader.ReadLine();
    }
}

Alternatively you could just use the StreamReader to read lines until you found the one you wanted. That way's slower but still an improvement over reading every single line.

using( Stream stream = File.Open(fileName, FileMode.Open) )
{
    using( StreamReader reader = new StreamReader(fileStream) )
    {
        string line = null;
        for( int i = 0; i < myLineNumber; ++i )
        {
            line = reader.ReadLine();
        }
    }
}

You can try use this simple conventional method:

Ctrl+Shift+R

replace

mysql_affected_rows

I understand that by saying "successful" you want to know if any rows have been updated. You can check it with this function.

This one-liner returns 1 (installed) or 0 (not installed) for the 'nano' package..

$(dpkg-query -W -f='${Status}' nano 2>/dev/null | grep -c "ok installed")

even if the package does not exist / is not available.

The example below installs the 'nano' package if it is not installed..

Summary:

• JGraphT if you are more interested in data structures and algorithms.
• JGraph if your primary focus is visualization.
• Jung, yWorks, and BFG are other things people tried using.
• Prefuse is a no no since one has to rewrite most of it.
• Google Guava if you need good datastructures only.
• Apache Commons Graph. Currently dormant, but provides implementations for many algorithms. See https://issues.apache.org/jira/browse/SANDBOX-458 for a list of implemented algorithms, also compared with Jung, GraphT, Prefuse, jBPT

I had the same issue, but was quite easy to solve. Follow the next steps:

1) In the Virtual Machine (VMWare) settings:

• Set the USB compatibility to be 2.0 instead of 3.0
• Check the setting "Show all USB input devices"

2) Add the device into the list of allowed development devices in your Apple Developer's account. Without that step there is no way to use your device in Xcode.

Next some instructions: Register a single device

.bashrc is not sourced when you log in using SSH. You need to source it in your .bash_profile like this:

Try this,this is working for me in angular JS

    let fileToUpload = `${documentLocation}/${documentType}.pdf`;
    let absoluteFilePath = path.resolve(__dirname, fileToUpload);
    console.log(`Uploading document ${absoluteFilePath}`);
    element.all(by.css("input[type='file']")).sendKeys(absoluteFilePath);

I know that some may want to smack me for re-opening old post, but if you feel so do it I just hope this may help someone else trying to set JDK 7 on Mac OS (using IntelliJ).

What I did to get this working on my machine is to:

• followed instructions on Oracle JDK7 Mac OS X Port for general installation
• in IntelliJ open/create new project so you can add new SDK (File > Project Structure)
• select Platform Settings > SDKs, press "+" (plus) sign to add new SDK
• select JSDK and navigate to /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home. Do not get it mistaken with /Users/YOUR_USERNAME/Library/Java/. This will link 4 JARs from "lib" directory (dt.jar, jconsole.jar, sa-jdi.jar and tools.jar)
• you will need also add JARs from /Library/Java/JavaVirtualMachines/JDK 1.7.0 Developer Preview.jdk/Contents/Home/jre/lib (charsets.jar, jce.jar, JObjC.jar, jsse.jar, management-agent.jar, resources.jar and rt.jar)

In the bash shell, surround arithmetic expressions with $(( ... ))

$ echo $(( 7 / 3 ))

memdump

There is a memcdump (sometimes memdump) command for that (part of libmemcached-tools), e.g.:

memcdump --servers=localhost

which will return all the keys.

memcached-tool

In the recent version of memcached there is also memcached-tool command, e.g.

memcached-tool localhost:11211 dump | less

which dumps all keys and values.

See also:

• What's the simplest way to get a dump of all memcached keys into a file?

I know this is a pretty old question but this was my solution that helped with visualizing the table so you can create a class structure. This is also using the HTML Agility Pack

HtmlDocument doc = new HtmlDocument();
doc.LoadHtml(@"<html><body><p><table id=""foo""><tr><th>hello</th></tr><tr><td>world</td></tr></table></body></html>");
var table = doc.DocumentNode.SelectSingleNode("//table");
var tableRows = table.SelectNodes("tr");
var columns = tableRows[0].SelectNodes("th/text()");
for (int i = 1; i < tableRows.Count; i++)
{
    for (int e = 0; e < columns.Count; e++)
    {
        var value = tableRows[i].SelectSingleNode($"td[{e + 1}]");
        Console.Write(columns[e].InnerText + ":" + value.InnerText);
    }
Console.WriteLine();
}

This solution worked very well for me, i'm doing this in a directive:

scope.$watch(attrs.testWatch, function() {.....}, true);

the true works pretty well and react for all the chnages (add, delete, or modify a field).

Here is a working plunker for play with it.

Deeply Watching an Array in AngularJS

I hope this can be useful for you. If you have any questions, feel free for ask, I'll try to help :)

Also, if you are using LINQ, you can apparently do something like myList.Select(methodGroup).

So, for example, I have:

private string DoSomethingToMyString(string input)
{
    // blah
}

Instead of explicitly stating the variable to be used like this:

public List<string> GetStringStuff()
{
    return something.getStringsFromSomewhere.Select(str => DoSomethingToMyString(str));
}

I can just omit the name of the var:

public List<string> GetStringStuff()
{
    return something.getStringsFromSomewhere.Select(DoSomethingToMyString);
}

The setting for the list throttle

• Open the SharePoint Central Administration,
• go to Application Management --> Manage Web Applications
• Click to select the web application that hosts your list (eg. SharePoint - 80)
• At the Ribbon, select the General Settings and select Resource Throttling
• Then, you can see the 5000 List View Threshold limit and you can edit the value you want.
• Click OK to save it.

It happened to me when I accidentally left the build in release mode.

In my testing all IMPL classes had the field "pid". This has worked for me:

public static int getPid(Process process) {
    try {
        Class<?> cProcessImpl = process.getClass();
        Field fPid = cProcessImpl.getDeclaredField("pid");
        if (!fPid.isAccessible()) {
            fPid.setAccessible(true);
        }
        return fPid.getInt(process);
    } catch (Exception e) {
        return -1;
    }
}

Just make sure the returned value is not -1. If it is, then parse the output of ps.

Upcoming pandas 0.13 version will allow to add rows through loc on non existing index data. However, be aware that under the hood, this creates a copy of the entire DataFrame so it is not an efficient operation.

Description is here and this new feature is called Setting With Enlargement.

Try:

document.getElementById("yourH1_element_Id").innerHTML = "yourTextHere";

$request->flash('request',$request);

<input type="text" class="form-control" name="name" value="{{ old('name') }}">

It works for me.

Did you forget to add the init.py in your package?

From the Jenkins home page:

1. Click Manage Jenkins.

Panel with opacity:

public class GlassyPanel : Panel
{
    const int WS_EX_TRANSPARENT = 0x20;  

    int opacity = 50;

    public int Opacity
    {
        get
        {
            return opacity;
        }
        set
        {
            if (value < 0 || value > 100) throw new ArgumentException("Value must be between 0 and 100");
            opacity = value;
        }
    }

    protected override CreateParams CreateParams
    {
        get
        {
            var cp = base.CreateParams;
            cp.ExStyle = cp.ExStyle | WS_EX_TRANSPARENT;

            return cp;
        }
    }

    protected override void OnPaint(PaintEventArgs e)
    {
        using (var b = new SolidBrush(Color.FromArgb(opacity * 255 / 100, BackColor)))
        {
            e.Graphics.FillRectangle(b, ClientRectangle);
        }

        base.OnPaint(e);
    }
}

Using Objective-C

You should register a UIApplicationWillEnterForegroundNotification in your ViewController's viewDidLoad method and whenever app comes back from background you can do whatever you want to do in the method registered for notification. ViewController's viewWillAppear or viewDidAppear won't be called when app comes back from background to foreground.

-(void)viewDidLoad{

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(doYourStuff)

  name:UIApplicationWillEnterForegroundNotification object:nil];
}

-(void)doYourStuff{

   // do whatever you want to do when app comes back from background.
}

Don't forget to unregister the notification you are registered for.

-(void)dealloc {
    [[NSNotificationCenter defaultCenter] removeObserver:self];
}

Note if you register your viewController for UIApplicationDidBecomeActiveNotification then your method would be called every time your app becomes active, It is not recommended to register viewController for this notification .

Using Swift

For adding observer you can use the following code

 override func viewDidLoad() {
    super.viewDidLoad()

     NotificationCenter.default.addObserver(self, selector: "doYourStuff", name: UIApplication.willEnterForegroundNotification, object: nil)
 }

 func doYourStuff(){
     // your code
 }

To remove observer you can use deinit function of swift.

deinit {
    NotificationCenter.default.removeObserver(self)
}

Because you initialized the top variable to -1 in your constructor, you need to increment the top variable in your push() method before you access the array. Note that I've changed the assignment to use ++top:

public void push(int i) 
{
    if (top == stack.length)
    {
        extendStack();
    }

    stack[++top]= i;
}

That will fix the ArrayIndexOutOfBoundsException you posted about. I can see other issues in your code, but since this is a homework assignment I'll leave those as "an exercise for the reader." :)

For C++:

As there is no special question for C++ tests, but the topic is very much the same, here is what helped me when I had the trouble with test discovery.

If you have only installed Desktop development with C++, then the solution is to also install Universal Windows Platform development with the optional C++ Universal Windows Platform tools. You can select these in the visual studio web installer.

Afterwards, rebuild your test project and the test discovery should work.

Btw, I created the unit test project in VS2017. It might be important, because some users mentioned, that they had discovery issues in projects, that were migrated from VS2015 to VS2017.

The issue of correctly pre-allocating a typed array in TypeScript was somewhat obscured for due to the array literal syntax, so it wasn't as intuitive as I first thought.

The correct way would be

var arr : Criminal[] = [];

This will give you a correctly typed, empty array stored in the variable 'arr'

Hope this helps others!

Whilst using Symbol as the enum value works fine for simple use cases, it can be handy to give properties to enums. This can be done by using an Object as the enum value containing the properties.

For example we can give each of the Colors a name and hex value:

/**
 * Enum for common colors.
 * @readonly
 * @enum {{name: string, hex: string}}
 */
const Colors = Object.freeze({
  RED:   { name: "red", hex: "#f00" },
  BLUE:  { name: "blue", hex: "#00f" },
  GREEN: { name: "green", hex: "#0f0" }
});

Including properties in the enum avoids having to write switch statements (and possibly forgetting new cases to the switch statements when an enum is extended). The example also shows the enum properties and types documented with the JSDoc enum annotation.

Equality works as expected with Colors.RED === Colors.RED being true, and Colors.RED === Colors.BLUE being false.

<style name="Theme.AppCompat.Light.NoActionBar.FullScreen" parent="@style/Theme.AppCompat.Light">

<item name="windowActionBar">false</item>
<item name="android:windowFullscreen">true</item>
<item name="android:windowContentOverlay">@null</item>

I know it's an old thread, but I felt compelled to mention the translate method, which is always a good way to replace all character codes above 128 (or other if necessary).

Usage : str.translate(table[, deletechars])

>>> trans_table = ''.join( [chr(i) for i in range(128)] + [' '] * 128 )

>>> 'Résultat'.translate(trans_table)
'R sultat'
>>> '6Â 918Â 417Â 712'.translate(trans_table)
'6  918  417  712'

Starting with Python 2.6, you can also set the table to None, and use deletechars to delete the characters you don't want as in the examples shown in the standard docs at http://docs.python.org/library/stdtypes.html.

With unicode strings, the translation table is not a 256-character string but a dict with the ord() of relevant characters as keys. But anyway getting a proper ascii string from a unicode string is simple enough, using the method mentioned by truppo above, namely : unicode_string.encode("ascii", "ignore")

As a summary, if for some reason you absolutely need to get an ascii string (for instance, when you raise a standard exception with raise Exception, ascii_message ), you can use the following function:

trans_table = ''.join( [chr(i) for i in range(128)] + ['?'] * 128 )
def ascii(s):
    if isinstance(s, unicode):
        return s.encode('ascii', 'replace')
    else:
        return s.translate(trans_table)

The good thing with translate is that you can actually convert accented characters to relevant non-accented ascii characters instead of simply deleting them or replacing them by '?'. This is often useful, for instance for indexing purposes.

USE THIS

I have had this exact issue for almost 2 weeks, extremely frustrating but I FINALLY found this site and it was a clear walk-through of what to do.

http://blog.summitcloud.com/2010/01/multivalue-parameters-with-stored-procedures-in-ssrs-sql/

I hope this helps people because it was exactly what I was looking for

In reference to redsquare's suggestion, I ended up doing this:

var selectItems = $("#edit-field-service-sub-cat-value option[value=" + title + "]").detach();

and then to reverse this:

$("#edit-field-service-sub-cat-value").append(selectItems);

If you are certain that you have a JDK installed (and not a JRE), you can specify the location of the JDK on the commandline when starting the installer (as mentioned in the error message you get).

These FAQ entries might also help you:

http://wiki.netbeans.org/FaqInstallJavahome
http://wiki.netbeans.org/FaqSuitableJvmNotFound

Use

table.put(key, val);

to add a new key/value pair or overwrite an existing key's value.

From the Javadocs:

V put(K key, V value): Associates the specified value with the specified key in this map (optional operation). If the map previously contained a mapping for the key, the old value is replaced by the specified value. (A map m is said to contain a mapping for a key k if and only if m.containsKey(k) would return true.)

The docs mention train_test_split is just a convenience function on top of shuffle split.

I just rearranged some of their code to make my own example. Note the actual solution is the middle block of code. The rest is imports, and setup for a runnable example.

from sklearn.model_selection import ShuffleSplit
from sklearn.utils import safe_indexing, indexable
from itertools import chain
import numpy as np
X = np.reshape(np.random.randn(20),(10,2)) # 10 training examples
y = np.random.randint(2, size=10) # 10 labels
seed = 1

cv = ShuffleSplit(random_state=seed, test_size=0.25)
arrays = indexable(X, y)
train, test = next(cv.split(X=X))
iterator = list(chain.from_iterable((
    safe_indexing(a, train),
    safe_indexing(a, test),
    train,
    test
    ) for a in arrays)
)
X_train, X_test, train_is, test_is, y_train, y_test, _, _  = iterator

print(X)
print(train_is)
print(X_train)

Now I have the actual indexes: train_is, test_is

[edit] Warning: Do not use rand() for statistics, simulation, cryptography or anything serious.

It's good enough to make numbers look random for a typical human in a hurry, no more.

See @Jefffrey's reply for better options, or this answer for crypto-secure random numbers.

Generally, the high bits show a better distribution than the low bits, so the recommended way to generate random numbers of a range for simple purposes is:

((double) rand() / (RAND_MAX+1)) * (max-min+1) + min

Note: make sure RAND_MAX+1 does not overflow (thanks Demi)!

The division generates a random number in the interval [0, 1); "stretch" this to the required range. Only when max-min+1 gets close to RAND_MAX you need a "BigRand()" function like posted by Mark Ransom.

This also avoids some slicing problems due to the modulo, which can worsen your numbers even more.

The built-in random number generator isn't guaranteed to have a the quality required for statistical simulations. It is OK for numbers to "look random" to a human, but for a serious application, you should take something better - or at least check its properties (uniform distribution is usually good, but values tend to correlate, and the sequence is deterministic). Knuth has an excellent (if hard-to-read) treatise on random number generators, and I recently found LFSR to be excellent and darn simple to implement, given its properties are OK for you.

I have to add that bundles are used by activities to pass data to themselves in the future.

When the screen rotates, or when another activity is started, the method protected void onSaveInstanceState(Bundle outState) is invoked, and the activity is destroyed. Later, another instance of the activity is created, and public void onCreate(Bundle savedInstanceState) is called. When the first instance of activity is created, the bundle is null; and if the bundle is not null, the activity continues some business started by its predecessor.

Android automatically saves the text in text fields, but it does not save everything, and subtle bugs sometimes appear.

The most common anti-pattern, though, is assuming that onCreate() does just initialization. It is wrong, because it also must restore the state.

There is an option to disable this "re-create activity on rotation" behavior, but it will not prevent restart-related bugs, it will just make them more difficult to mention.

Note also that the only method whose call is guaranteed when the activity is going to be destroyed is onPause(). (See the activity life cycle graph in the docs.)

my opinion is that:

<link rel="stylesheet" href="{{ URL::to('/css/app.css') }}">

is the best method to route to your css files.

The URL::to() also works for js

It depends on how you store the parsed CSV, but generally you want the del operator.

If you have an array of dicts:

input = [ {'day':01, 'month':04, 'year':2001, ...}, ... ]
for E in input: del E['year']

If you have an array of arrays:

input = [ [01, 04, 2001, ...],
          [...],
          ...
        ]
for E in input: del E[2]

Try this: tar -cf file.tar file-to-compress ; xz -z file.tar

Note:

1. tar.gz and tar.xz are not the same; xz provides better compression.
2. Don't use pipe | because this runs commands simultaneously. Using ; or & executes commands one after another.

Maybe just restart postgres => sudo service postgresql restart

A solution that works for S3 modified from Minkymorgan.

Simply pass the temporary partitioned directory path (with different name than final path) as the srcPath and single final csv/txt as destPath Specify also deleteSource if you want to remove the original directory.

/**
* Merges multiple partitions of spark text file output into single file. 
* @param srcPath source directory of partitioned files
* @param dstPath output path of individual path
* @param deleteSource whether or not to delete source directory after merging
* @param spark sparkSession
*/
def mergeTextFiles(srcPath: String, dstPath: String, deleteSource: Boolean): Unit =  {
  import org.apache.hadoop.fs.FileUtil
  import java.net.URI
  val config = spark.sparkContext.hadoopConfiguration
  val fs: FileSystem = FileSystem.get(new URI(srcPath), config)
  FileUtil.copyMerge(
    fs, new Path(srcPath), fs, new Path(dstPath), deleteSource, config, null
  )
}

Since the post is active 2 Months ago. so I thought to give my input as well.

In my case i recieve date from a card reader which comes in dd/mm/yyyy format.

what i do. E.g.

var d="16/09/2019" // date received from card_x000D_
function filldate(){_x000D_
    document.getElementById('cardexpirydate').value=d.split('/').reverse().join("-");_x000D_
    }

<input type="date" id="cardexpirydate">_x000D_
<br /><br />_x000D_
<input type="button" value="fill the date" onclick="filldate();">

what the code do:

1. it splits the date which i get as dd/mm/yyyy (using split()) on basis of "/" and makes an array,
2. it then reverse the array (using reverse()) since the date input supports the reverse of what i get.
3. then it joins (using join())the array to a string according the format required by the input field

All this is done in a single line.

i thought this will help some one so i wrote this.

Most of the answers provided here address the number of incoming requests to your backend webservice, not the number of outgoing requests you can make from your ASP.net application to your backend service.

It's not your backend webservice that is throttling your request rate here, it is the number of open connections your calling application is willing to establish to the same endpoint (same URL).

You can remove this limitation by adding the following configuration section to your machine.config file:

<configuration>
  <system.net>
    <connectionManagement>
      <add address="*" maxconnection="65535"/>
    </connectionManagement>
  </system.net>
</configuration>

You could of course pick a more reasonable number if you'd like such as 50 or 100 concurrent connections. But the above will open it right up to max. You can also specify a specific address for the open limit rule above rather than the '*' which indicates all addresses.

MSDN Documentation for System.Net.connectionManagement

Another Great Resource for understanding ConnectManagement in .NET

Hope this solves your problem!

EDIT: Oops, I do see you have the connection management mentioned in your code above. I will leave my above info as it is relevant for future enquirers with the same problem. However, please note there are currently 4 different machine.config files on most up to date servers!

There is .NET Framework v2 running under both 32-bit and 64-bit as well as .NET Framework v4 also running under both 32-bit and 64-bit. Depending on your chosen settings for your application pool you could be using any one of these 4 different machine.config files! Please check all 4 machine.config files typically located here:

• C:\Windows\Microsoft.NET\Framework\v2.0.50727\CONFIG
• C:\Windows\Microsoft.NET\Framework64\v2.0.50727\CONFIG
• C:\Windows\Microsoft.NET\Framework\v4.0.30319\Config
• C:\Windows\Microsoft.NET\Framework64\v4.0.30319\Config

For windows

npm install -g grunt-cli

npm install load-grunt-tasks

Then run

grunt

Sometimes if you change the starting activity you have to click edit in the run dropdown play button and in app change the Launch Options Activity to the one you have set the LAUNCHER intent filter in the manifest.

If you push it out through MDM it should auto-trust the application (https://support.apple.com/en-gb/HT204460), but it still has to verify the certs etc with Apple to ensure they've not been revoked etc i presume. I had this message preventing the application from launching and it was only when the proxy information was configured so it i could use the internet that it went away after a couple more launch attempts.

Here, I solved this issue by making two functions.

1. dynamicColors() to generate random color

function dynamicColors() {
    var r = Math.floor(Math.random() * 255);
    var g = Math.floor(Math.random() * 255);
    var b = Math.floor(Math.random() * 255);
    return "rgba(" + r + "," + g + "," + b + ", 0.5)";
}

2. poolColors() to create array of colors

function poolColors(a) {
    var pool = [];
    for(i = 0; i < a; i++) {
        pool.push(dynamicColors());
    }
    return pool;
}

Then, just pass it

datasets: [{
    data: arrData,
    backgroundColor: poolColors(arrData.length),
    borderColor: poolColors(arrData.length),
    borderWidth: 1
}]

I had this error

(Illuminate\Contracts\Container\BindingResolutionException Target class [App\Http\Controllers\ControllerFileName] does not exist.

Solution: just check your class Name, it should be the exact same of your file name.

As cardern has said list will do the job.

Here is how you can use a named range.

Select your range and enter a new name:

Select your cell that you want a drop down to be in and goto data tab -> data validation.

Select 'List' from the 'Allow' Drop down menu.

Enter your named range like this:

Now you have a drop down linked to your range. If you insert new rows in your range everything will update automatically.

If you want to add REM at the beginning of each line instead of using GOTO, you can use Notepad++ to do this easily following these steps:

1. Select the block of lines
2. hit Ctrl-Q

Repeat steps to uncomment

I was also running the same problem when I updated to xcode 5 it removed older sdk. But I taken the copy of older SDK from another computer and the same you can download from following link.

http://www.4shared.com/zip/NlPgsxz6/iPhoneOS61sdk.html
(www.4shared.com test account [email protected]/test)

There are 2 ways to work with.

1) Unzip and paste this folder to /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs & restart the xcode.

But this might again removed by Xcode if you update xcode.

2) Another way is Unzip and paste where you want and go to /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs and create a symbolic link here, so that the SDK will remain same even if you update the Xcode.

Another change I made, Build Setting > Architectures > standard (not 64) so list all the versions of Deployment Target

No need to download the zip if you only wanted to change the deployment target.

Here are some screenshots.

Add a width to the .child elements. I personally would use percentages on the margin-left if you want to have it always 4 per row.

DEMO

.child {
    display: inline-block;
    background: blue;
    margin: 10px 0 0 2%;
    flex-grow: 1;
    height: 100px;
    width: calc(100% * (1/4) - 10px - 1px);
}

This is what worked for me when I got a similar error in Windows; 1. Install virtualenv

pip install virtualenve

2. Create a virtualenv

   virtualenv flask

3. Navigate to Scripts and activate the virtualenv

   activate

4. Install Flask

   python -m pip install flask

5. Check if flask is installed

   python -m pip list

Simply do this:

def which_index(self):
    return [
        i for i in range(len(self.states))
        if self.states[i] == True
    ]

This is a java 8 solution.

public int[] solution (String s, String subString){
        int initialIndex = s.indexOf(subString);
        List<Integer> indexList = new ArrayList<>();
        while (initialIndex >=0){
            indexList.add(initialIndex);
            initialIndex = s.indexOf(subString, initialIndex+1);
        }
        int [] intA = indexList.stream().mapToInt(i->i).toArray();
        return intA;
    }

Shallow copy with copy.copy()

#!/usr/bin/env python3

import copy

class C():
    def __init__(self):
        self.x = [1]
        self.y = [2]

# It copies.
c = C()
d = copy.copy(c)
d.x = [3]
assert c.x == [1]
assert d.x == [3]

# It's shallow.
c = C()
d = copy.copy(c)
d.x[0] = 3
assert c.x == [3]
assert d.x == [3]

Deep copy with copy.deepcopy()

#!/usr/bin/env python3
import copy
class C():
    def __init__(self):
        self.x = [1]
        self.y = [2]
c = C()
d = copy.deepcopy(c)
d.x[0] = 3
assert c.x == [1]
assert d.x == [3]

You can also get the WINDOW width and height, avoiding browser toolbars and other stuff. It is the real usable area in browser's window.

To do this, use: window.innerWidth and window.innerHeight properties (see doc at w3schools).

In most cases it will be the best way, in example, to display a perfectly centred floating modal dialog. It allows you to calculate positions on window, no matter which resolution orientation or window size is using the browser.

In csh (as opposed to bash) you can do exactly what you want.

alias print 'lpr \!^ -Pps5'
print memo.txt

The notation \!^ causes the argument to be inserted in the command at this point.

The ! character is preceeded by a \ to prevent it being interpreted as a history command.

You can also pass multiple arguments:

alias print 'lpr \!* -Pps5'
print part1.ps glossary.ps figure.ps

(Examples taken from http://unixhelp.ed.ac.uk/shell/alias_csh2.1.html .)

If you want to use the GUI... click/double-click the table and select the Data tab. Click in the column value you want to set to (null). Select the value and delete it. Hit the commit button (green check-mark button). It should now be null.

The accepted answer only renamed the user but the privileges were left behind.

I'd recommend using:

RENAME USER 'foo'@'1.2.3.4' TO 'foo'@'1.2.3.5';

According to MySQL documentation:

RENAME USER causes the privileges held by the old user to be those held by the new user.

git config --global fetch.prune true

To always --prune for git fetch and git pull in all your Git repositories:

git config --global fetch.prune true

This above command appends in your global Git configuration (typically ~/.gitconfig) the following lines. Use git config -e --global to view your global configuration.

[fetch]
    prune = true

git config remote.origin.prune true

To always --prune but from one single repository:

git config remote.origin.prune true
                 #^^^^^^
                 #replace with your repo name

This above command adds in your local Git configuration (typically .git/config) the below last line. Use git config -e to view your local configuration.

[remote "origin"]
    url = xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
    fetch = +refs/heads/*:refs/remotes/origin/*
    prune = true

You can also use --global within the second command or use instead --local within the first command.

git config --global gui.pruneDuringFetch true

If you use git gui you may also be interested by:

git config --global gui.pruneDuringFetch true

that appends:

[gui]
    pruneDuringFetch = true

References

The corresponding documentations from git help config:

--global

  For writing options: write to global ~/.gitconfig file rather than the repository .git/config, write to $XDG_CONFIG_HOME/git/config file if this file exists and the ~/.gitconfig file doesn’t.

--local

  For writing options: write to the repository .git/config file. This is the default behavior.

fetch.prune

  If true, fetch will automatically behave as if the --prune option was given on the command line. See also remote.<name>.prune.

gui.pruneDuringFetch

  "true" if git-gui should prune remote-tracking branches when performing a fetch. The default value is "false".

remote.<name>.prune

  When set to true, fetching from this remote by default will also remove any remote-tracking references that no longer exist on the remote (as if the --prune option was given on the command line). Overrides fetch.prune settings, if any.

There are a lot more techniques to factoring than the sieve of Atkin. For example suppose we want to factor 5893. Well its sqrt is 76.76... Now we'll try to write 5893 as a product of squares. Well (77*77 - 5893) = 36 which is 6 squared, so 5893 = 77*77 - 6*6 = (77 + 6)(77-6) = 83*71. If that hadn't worked we'd have looked at whether 78*78 - 5893 was a perfect square. And so on. With this technique you can quickly test for factors near the square root of n much faster than by testing individual primes. If you combine this technique for ruling out large primes with a sieve, you will have a much better factoring method than with the sieve alone.

And this is just one of a large number of techniques that have been developed. This is a fairly simple one. It would take you a long time to learn, say, enough number theory to understand the factoring techniques based on elliptic curves. (I know they exist. I don't understand them.)

Therefore unless you are dealing with small integers, I wouldn't try to solve that problem myself. Instead I'd try to find a way to use something like the PARI library that already has a highly efficient solution implemented. With that I can factor a random 40 digit number like 124321342332143213122323434312213424231341 in about .05 seconds. (Its factorization, in case you wondered, is 29*439*1321*157907*284749*33843676813*4857795469949. I am quite confident that it didn't figure this out using the sieve of Atkin...)

I know this is long stagnant topic, but in case anyone searches here is how I deal with multi table foreign keys. With this technique you do not have any DBA enforced cascade operations, so please make sure you deal with DELETE and such in your code.

Table 1 Fruit
pk_fruitid, name
1, apple

Table 2 Meat
Pk_meatid, name

Table 3 Entity's

1, fruit
2, meat
3, desert

Table 4 Basket (Table using fk_s)
PK_basketid, fk_entityid, pseudo_entityrow
1, 2, 2 (Chicken - entity denotes meat table, pseudokey denotes row in indictaed table)
2, 1, 1 (Apple)
3, 1, 2 (pear)
4, 3, 1 (cheesecake)

Besides the .htaccess way, I have seen a useful pattern in various frameworks, for example in ruby on rails. They have a separate pub/ directory in the application root directory and the library directories are living in directories at the same level as pub/. Something like this (not ideal, but you get the idea):

app/
 |
 +--pub/
 |
 +--lib/
 |
 +--conf/
 |
 +--models/
 |
 +--views/
 |
 +--controllers/

You set up your web server to use pub/ as document root. This offers better protection to your scripts: while they can reach out from the document root to load necessary components it is impossible to access the components from the internet. Another benefit besides security is that everything is in one place.

This setup is better than just creating checks in every single included file because "access not permitted" message is a clue to attackers, and it is better than .htaccess configuration because it is not white-list based: if you screw up the file extensions it will not be visible in the lib/, conf/ etc. directories.

>>> format(123, 'b')
'1111011'

Integer objects are immutable. You can't change the value of the integer held by the object itself, but you can just create a new Integer object to hold the result:

Integer start = new Integer(5);
Integer end = start + 5; // end == 10;

Interfaces cannot require instance variables to be defined -- only methods.

(Variables can be defined in interfaces, but they do not behave as might be expected: they are treated as final static.)

Happy coding.

Use table alias in subquery:

INSERT INTO customers
  ( customer_id, firstname, surname )
VALUES 
  ((SELECT MAX( customer_id ) FROM customers C) +1, 'jim', 'sock')

This is another method . Passing array as a pointer to the function
void generateArray(int *array,  int size) {
    srand(time(0));
    for (int j=0;j<size;j++)
        array[j]=(0+rand()%9);
}

int main(){
    const int size=5;
    int a[size];
    generateArray(a, size);
    return 0;
}

So here's how to do that:

In the bottom bar of VSCode, you'll see the label UTF-8. Click it. A popup opens. Click Save with encoding. You can now pick a new encoding for that file.

Alternatively, you can change the setting globally in Workspace/User settings using the setting "files.encoding": "utf8". If using the graphical settings page in VSCode, simply search for encoding. Do note however that this only applies to newly created files.

I use:

let jsonFile = {};    
let schemaJson = {};    
schemaJson["properties"] = {};    
schemaJson["properties"]["key"] = "value";
jsonFile.concat(schemaJson);

import re
string = re.sub('[ \t\n]+', ' ', 'The     quick brown                \n\n             \t        fox')

This will remove all the tabs, new lines and multiple white spaces with single white space.

Just drop

<script>
myfunction();
</script>

in the body where you want it to be called, understanding that when the page loads and the browser reaches that point, that's when the call will occur.

Resolve is also more straightforward

from django.urls import resolve

resolve('edit_project', project_id=4)

Well, the naive approach (combine 2 lists into large one and sort) will be O(N*log(N)) complexity. On the other hand, if you implement the merge manually (i do not know about any ready code in python libs for this, but i'm no expert) the complexity will be O(N), which is clearly faster. The idea is described wery well in post by Barry Kelly.

Remember jQuery is a JavaScript library, i.e. like an extension. That means you can use both jQuery and JavaScript in the same function (restrictions apply).

You declare/create variables in the same way as in Javascript: var example;

However, you can use jQuery for assigning values to variables:

var example = $("#unique_product_code").html();

Instead of pure JavaScript:

var example = document.getElementById("unique_product_code").innerHTML;

As I understand you want to empty your array as you press your back button and pop to your previous ViewController let your Array which you loaded on this screen is

    self.dismissViewControllerAnimated(true, completion: nil)
} 

I couldn't uninstall yarn on windows and I tried every single answer here, but every time I ran yarn -v, the command worked. But then I realized that there is another thing that can affect this.

If you on windows (not sure if this also happens in mac) and using nvm, one problem that can happen is that you have installed nvm without uninstalling npm, and the working yarn command is from your old yarn version from the old npm.

So what you need to do is follow this step from the nvm docs

You should also delete the existing npm install location (e.g. "C:\Users<user>\AppData\Roaming\npm"), so that the nvm install location will be correctly used instead. Backup the global npmrc config (e.g. C:\Users&lt;user>\AppData\Roaming\npm\etc\npmrc), if you have some important settings there, or copy the settings to the user config C:\Users&lt;user>.npmrc.

And to confirm that you problem is with the old npm, you will probably see the yarn.cmd file inside the C:\Users\<user>\AppData\Roaming\npm folder.

Solution #1: Your statement

.Range(Cells(RangeStartRow, RangeStartColumn), Cells(RangeEndRow, RangeEndColumn)).PasteSpecial xlValues

does not refer to a proper Range to act upon. Instead,

.Range(.Cells(RangeStartRow, RangeStartColumn), .Cells(RangeEndRow, RangeEndColumn)).PasteSpecial xlValues

does (and similarly in some other cases).

Solution #2: Activate Worksheets("Cable Cards") prior to using its cells.

Explanation: Cells(RangeStartRow, RangeStartColumn) (e.g.) gives you a Range, that would be ok, and that is why you often see Cells used in this way. But since it is not applied to a specific object, it applies to the ActiveSheet. Thus, your code attempts using .Range(rng1, rng2), where .Range is a method of one Worksheet object and rng1 and rng2 are in a different Worksheet.

There are two checks that you can do to make this quite evident:

1. Activate your Worksheets("Cable Cards") prior to executing your Sub and it will start working (now you have well-formed references to Ranges). For the code you posted, adding .Activate right after With... would indeed be a solution, although you might have a similar problem somewhere else in your code when referring to a Range in another Worksheet.

2. With a sheet other than Worksheets("Cable Cards") active, set a breakpoint at the line throwing the error, start your Sub, and when execution breaks, write at the immediate window

   Debug.Print Cells(RangeStartRow, RangeStartColumn).Address(external:=True)

   Debug.Print .Cells(RangeStartRow, RangeStartColumn).Address(external:=True)

   and see the different outcomes.

Conclusion: Using Cells or Range without a specified object (e.g., Worksheet, or Range) might be dangerous, especially when working with more than one Sheet, unless one is quite sure about what Sheet is active.

You need to be wary of XSS when doing stuff like this:

document.getElementById('<%= Label1.ClientID %>').style.display

The chances are that no-one will be able to tamper with the ClientID of Label1 in this instance, but just to be on the safe side you might want pass it's value through one of the AntiXss library's methods:

document.getElementById('<%= AntiXss.JavaScriptEncode(Label1.ClientID) %>').style.display

The only thing I would add to Mark Peters solution is that you don't need to iterate over the ArrayList - you should be able to use the addAll(Collection) method on the Set. You only need to iterate over the entire list to do the summations.

function Uint8ToBase64(u8Arr){
  var CHUNK_SIZE = 0x8000; //arbitrary number
  var index = 0;
  var length = u8Arr.length;
  var result = '';
  var slice;
  while (index < length) {
    slice = u8Arr.subarray(index, Math.min(index + CHUNK_SIZE, length)); 
    result += String.fromCharCode.apply(null, slice);
    index += CHUNK_SIZE;
  }
  return btoa(result);
}

You can use this function if you have a very large Uint8Array. This is for Javascript, can be useful in case of FileReader readAsArrayBuffer.

I'm not positive what you're asking, but if you're looking for an example of when one would want to use a null key, I use them often in maps to represent the default case (i.e. the value that should be used if a given key isn't present):

Map<A, B> foo;
A search;
B val = foo.containsKey(search) ? foo.get(search) : foo.get(null);

HashMap handles null keys specially (since it can't call .hashCode() on a null object), but null values aren't anything special, they're stored in the map like anything else

I don't know of any methodology to use to fix things like this. I don't think it would be possible to come up with one either for the very issue at hand is that your program's behavior is undefined (I don't know of any case when SEGFAULT hasn't been caused by some sort of UB).

There are all kinds of "methodologies" to avoid the issue before it arises. One important one is RAII.

Besides that, you just have to throw your best psychic energies at it.

JOIN t2 ON t1.id=t2.id AND t1.date=t2.date

You cannot call a non-static method from the main without instance creation, whereas you can simply call a static method. The main logic behind this is that, whenever you execute a .class file all the static data gets stored in the RAM and however, JVM(java virtual machine) would be creating context of the mentioned class which contains all the static data of the class. Therefore, it is easy to access the static data from the class without instance creation.The object contains the non-static data Context is created only once, whereas object can be created any number of times. context contains methods, variables etc. Whereas, object contains only data. thus, the an object can access both static and non-static data from the context of the class

Create xml file like edit_text_design.xml and save it to your drawable folder

The import allows the java programmer to access classes of a package without package qualification.

The static import feature allows to access the static members of a class without the class qualification.

The import provides accessibility to classes and interface whereas static import provides accessibility to static members of the class.

Example :

With import

import java.lang.System.*;    
class StaticImportExample{  
    public static void main(String args[]){  

       System.out.println("Hello");
       System.out.println("Java");  

  }   
} 

With static import

import static java.lang.System.*;    
class StaticImportExample{  
  public static void main(String args[]){  

   out.println("Hello");//Now no need of System.out  
   out.println("Java");  

 }   
}

Use the AssemblyInfo task from the MSBuild Community Tasks (http://msbuildtasks.tigris.org/) project, and integrate it into your .csproj/.vbproj file.

It has a number of options, including one to tie the version number to the date and time of day.

Recommended.

"Sleep" state connections are most often created by code that maintains persistent connections to the database.

This could include either connection pools created by application frameworks, or client-side database administration tools.

As mentioned above in the comments, there is really no reason to worry about these connections... unless of course you have no idea where the connection is coming from.

(CAVEAT: If you had a long list of these kinds of connections, there might be a danger of running out of simultaneous connections.)

Use a semicolon

OpenFileDialog of = new OpenFileDialog();
of.Filter = "Excel Files|*.xls;*.xlsx;*.xlsm";

I use Spring Boot, my solution to the problem was

Hope it helps someone.

From the manual:

require() is identical to include() except upon failure it will also produce a fatal E_COMPILE_ERROR level error. In other words, it will halt the script whereas include() only emits a warning (E_WARNING) which allows the script to continue.

The same is true for the _once() variants.

Firstly you don't do this in your view. You do it in the controller and return a view model to the view so that the view doesn't need to care about custom HTTP headers but just displaying data on the view model:

public ActionResult Index()
{
    var xyzComponent = Request.Headers["xyzComponent"];
    var model = new MyModel 
    {
        IsCustomHeaderSet = (xyzComponent != null)
    }
    return View(model);
}

First, you should install "platformio-ide-terminal": Open "Preferences ?," >> Click "+ Install" >> In "Search packages" type "platformio-ide-terminal" >> Click "Install".

And answering exactly the question. If you have previously installed, just use:

• Shortcut: ctrl-` or Option+Command+T (??T)
• by Menu: Go to Packages > platformio-ide-terminal [or other] > New terminal

Since you said you only wanted to pass one parameter and it did not seem to matter which, you could pass the resource identifier in and then find out the string name for it, thus:

String name = getResources().getResourceEntryName(id);

This might be the most efficient way of obtaining both values. You don't have to mess around finding just the "icon" part from a longer string.

The unfortunate truth about AJAX and the 302 redirect is that you can't get the headers from the return because the browser never gives them to the XHR. When a browser sees a 302 it automatically applies the redirect. In this case, you would see the header in firebug because the browser got it, but you would not see it in ajax, because the browser did not pass it. This is why the success and the error handlers never get called. Only the complete handler is called.

http://www.checkupdown.com/status/E302.html

The 302 response from the Web server should always include an alternative URL to which redirection should occur. If it does, a Web browser will immediately retry the alternative URL. So you never actually see a 302 error in a Web browser

Here are some stackoverflow posts on the subject. Some of the posts describe hacks to get around this issue.

Open Git Bash and run the command if you want to completely disable SSL verification.

git config --global http.sslVerify false

Note: This solution may open you to attacks like man-in-the-middle attacks. Therefore turn on verification again as soon as possible:

git config --global http.sslVerify true

How about:

DELETE guide_category  
  WHERE id_guide_category IN ( 

        SELECT id_guide_category 
          FROM guide_category AS gc
     LEFT JOIN guide AS g 
            ON g.id_guide = gc.id_guide
         WHERE g.title IS NULL

  )

If you want to get the key of a single value, the following would help:

def get_key(b): # the value is passed to the function
    for k, v in mydic.items():
        if v.lower() == b.lower():
            return k

In pythonic way:

c = next((x for x, y in mydic.items() if y.lower() == b.lower()), \
     "Enter a valid 'Value'")
print(c)

I don't understand why everyone is making this complicated (answers).

I'll just leave this here.

So above would be:

• Signal Unit: 4 bits
• Baud Rate [Signal Units per second]: 1000 Bd (baud)
• Bit Rate [Baud Rate * Signal Unit]: 4000 bps (bits per second)

Bit rate and Baud rate, these two terms are often used in data communication. Bit rate is simply the number of bits (i.e., 0’s and 1’s) transmitted per unit time. While Baud rate is the number of signal units transmitted per unit time that is needed to represent those bits.

1. Download the latest CMake Mac binary distribution here: https://cmake.org/download/ (current latest is: https://cmake.org/files/v3.17/cmake-3.17.1-Darwin-x86_64.dmg)

2. Double click the downloaded .dmg file to install it. In the window that pops up, drag the CMake icon into the Application folder.

3. Add this line to your .bashrc file: PATH="/Applications/CMake.app/Contents/bin":"$PATH"

4. Reload your .bashrc file: source ~/.bashrc

5. Verify the latest cmake version is installed: cmake --version

6. You can launch the CMake GUI by clicking on LaunchPad and typing cmake. Click on the CMake icon that appears.

There are two best contenders:

1. Create a 1×1 image data, set the color, and putImageData at the location:

   var id = myContext.createImageData(1,1); // only do this once per page
   var d  = id.data;                        // only do this once per page
   d[0]   = r;
   d[1]   = g;
   d[2]   = b;
   d[3]   = a;
   myContext.putImageData( id, x, y );     
   

2. Use fillRect() to draw a pixel (there should be no aliasing issues):

   ctx.fillStyle = "rgba("+r+","+g+","+b+","+(a/255)+")";
   ctx.fillRect( x, y, 1, 1 );
   

You can test the speed of these here: http://jsperf.com/setting-canvas-pixel/9 or here https://www.measurethat.net/Benchmarks/Show/1664/1

I recommend testing against browsers you care about for maximum speed. As of July 2017, fillRect() is 5-6× faster on Firefox v54 and Chrome v59 (Win7x64).

Other, sillier alternatives are:

• using getImageData()/putImageData() on the entire canvas; this is about 100× slower than other options.

• creating a custom image using a data url and using drawImage() to show it:

  var img = new Image;
  img.src = "data:image/png;base64," + myPNGEncoder(r,g,b,a);
  // Writing the PNGEncoder is left as an exercise for the reader
  

• creating another img or canvas filled with all the pixels you want and use drawImage() to blit just the pixel you want across. This would probably be very fast, but has the limitation that you need to pre-calculate the pixels you need.

Note that my tests do not attempt to save and restore the canvas context fillStyle; this would slow down the fillRect() performance. Also note that I am not starting with a clean slate or testing the exact same set of pixels for each test.

Just add .pack between the name and the extension in the <script> tag in src. i.e.:

<script src="name.pack.js">

A space may only be encoded to "+" in the "application/x-www-form-urlencoded" content-type key-value pairs query part of an URL. In my opinion, this is a MAY, not a MUST. In the rest of URLs, it is encoded as %20.

In my opinion, it's better to always encode spaces as %20, not as "+", even in the query part of an URL, because it is the HTML specification (RFC-1866) that specified that space characters should be encoded as "+" in "application/x-www-form-urlencoded" content-type key-value pairs (see paragraph 8.2.1. subparagraph 1.)

This way of encoding form data is also given in later HTML specifications. For example, look for relevant paragraphs about application/x-www-form-urlencoded in HTML 4.01 Specification, and so on.

Here is a sample string in URL where the HTML specification allows encoding spaces as pluses: "http://example.com/over/there?name=foo+bar". So, only after "?", spaces can be replaced by pluses. In other cases, spaces should be encoded to %20. But since it's hard to correctly determine the context, it's the best practice to never encode spaces as "+".

I would recommend to percent-encode all character except "unreserved" defined in RFC-3986, p.2.3

unreserved = ALPHA / DIGIT / "-" / "." / "_" / "~"

The implementation depends on the programming language that you chose.

If your URL contains national characters, first encode them to UTF-8 and then percent-encode the result.

All the other solutions here are OS dependent. An independent solution for any OS uses socket.io as follows.

package.json has two scripts:

"scripts": {
  "start": "node server.js",
  "stop": "node server.stop.js"
}

server.js - Your usual express stuff lives here

const express = require('express');
const app = express();
const server = http.createServer(app);
server.listen(80, () => {
  console.log('HTTP server listening on port 80');
});

// Now for the socket.io stuff - NOTE THIS IS A RESTFUL HTTP SERVER
// We are only using socket.io here to respond to the npmStop signal
// To support IPC (Inter Process Communication) AKA RPC (Remote P.C.)

const io = require('socket.io')(server);
io.on('connection', (socketServer) => {
  socketServer.on('npmStop', () => {
    process.exit(0);
  });
});

server.stop.js

const io = require('socket.io-client');
const socketClient = io.connect('http://localhost'); // Specify port if your express server is not using default port 80

socketClient.on('connect', () => {
  socketClient.emit('npmStop');
  setTimeout(() => {
    process.exit(0);
  }, 1000);
});

Test it out

npm start (to start your server as usual)

npm stop (this will now stop your running server)

The above code has not been tested (it is a cut down version of my code, my code does work) but hopefully it works as is. Either way, it provides the general direction to take if you want to use socket.io to stop your server.

How about this?

$( document ).ready(function() {
    $('#fixed').width($('#wrap').width());
});

By using jquery you can set any kind of width :)

EDIT: As stated by dream in the comments, using JQuery just for this effect is pointless and even counter productive. I made this example for people who use JQuery for other stuff on their pages and consider using it for this part also. I apologize for any inconvenience my answer caused.

I believe that Maven has a bad rep because most detractors have not observed the combination of Maven + Hudson + Sonar. If they had, they would be asking "how do I get started"?

Declaring array's of pointer to functions for implementing finite state machines.

int (* fsm[])(void) = { ... }

The most pleasing advantage is that it is simple to force each stimulus/state to check all code paths.

In an embedded system, I'll often map an ISR to point to such a table and revector it as needed (outside the ISR).

The following query can be used to detemine tablespace and other params:

select df.tablespace_name "Tablespace",
       totalusedspace "Used MB",
       (df.totalspace - tu.totalusedspace) "Free MB",
       df.totalspace "Total MB",
       round(100 * ( (df.totalspace - tu.totalusedspace)/ df.totalspace)) "Pct. Free"
  from (select tablespace_name,
               round(sum(bytes) / 1048576) TotalSpace
          from dba_data_files 
         group by tablespace_name) df,
       (select round(sum(bytes)/(1024*1024)) totalusedspace,
               tablespace_name
          from dba_segments 
         group by tablespace_name) tu
 where df.tablespace_name = tu.tablespace_name 
   and df.totalspace <> 0;

Source: https://community.oracle.com/message/1832920

For your case if you want to know the partition name and it's size just run this query:

select owner,
       segment_name,
       partition_name,
       segment_type,
       bytes / 1024/1024 "MB" 
  from dba_segments 
 where owner = <owner_name>;

    boolean isBeforeToday(Date d) {
        Date today = new Date();
        today.setHours(0);
        today.setMinutes(0);
        today.setSeconds(0);
        return d.before(today);
    }

Those two parameters (or variants of) are sent, by convention, with all events.

• sender: The object which has raised the event
• e an instance of EventArgs including, in many cases, an object which inherits from EventArgs. Contains additional information about the event, and sometimes provides ability for code handling the event to alter the event somehow.

In the case of the events you mentioned, neither parameter is particularly useful. The is only ever one page raising the events, and the EventArgs are Empty as there is no further information about the event.

Looking at the 2 parameters separately, here are some examples where they are useful.

sender

Say you have multiple buttons on a form. These buttons could contain a Tag describing what clicking them should do. You could handle all the Click events with the same handler, and depending on the sender do something different

private void HandleButtonClick(object sender, EventArgs e)
{
    Button btn = (Button)sender;
    if(btn.Tag == "Hello")
      MessageBox.Show("Hello")
    else if(btn.Tag == "Goodbye")
       Application.Exit();
    // etc.
}

Disclaimer : That's a contrived example; don't do that!

e

Some events are cancelable. They send CancelEventArgs instead of EventArgs. This object adds a simple boolean property Cancel on the event args. Code handling this event can cancel the event:

private void HandleCancellableEvent(object sender, CancelEventArgs e)
{
    if(/* some condition*/)
    {
       // Cancel this event
       e.Cancel = true;
    }
}

One very nasty gotcha which just wasted a bit of my time debugging - you may find yourself prompted by auto-complete to try using doesContain which seems to work.

Except, doesContain uses an id comparison instead of the hash comparison used by objectForKey so if you have a dictionary with string keys it will return NO to a doesContain.

NSMutableDictionary* keysByName = [[NSMutableDictionary alloc] init];
keysByName[@"fred"] = @1;
NSString* test = @"fred";

if ([keysByName objectForKey:test] != nil)
    NSLog(@"\nit works for key lookups");  // OK
else
    NSLog(@"\nsod it");

if (keysByName[test] != nil)
    NSLog(@"\nit works for key lookups using indexed syntax");  // OK
else
    NSLog(@"\nsod it");

if ([keysByName doesContain:@"fred"])
    NSLog(@"\n doesContain works literally");
else
    NSLog(@"\nsod it");  // this one fails because of id comparison used by doesContain

One should NEVER call System.exit(0) for these reasons:

1. It is a hidden "goto" and "gotos" break the control flow. Relying on hooks in this context is a mental mapping every developer in the team has to be aware of.

2. Quitting the program "normally" provides the same exit code to the operating system as System.exit(0) so it is redundant.

   If your program cannot quit "normally" you have lost control of your development [design]. You should have always full control of the system state.

3. Programming problems such as running threads that are not stopped normally become hidden.
4. You may encounter an inconsistent application state interrupting threads abnormally. (Refer to #3)

By the way: Returning other return codes than 0 does make sense if you want to indicate abnormal program termination.

Sure.

FOR %%A IN (%Date:/=%) DO SET Today=%%A
7z a QuickBackup%TODAY%.zip *.backup

That is DDMMYYYY format.

Here's YYYYDDMM:

FOR %%A IN (%Date%) DO (
    FOR /F "tokens=1-3 delims=/-" %%B in ("%%~A") DO (
        SET Today=%%D%%B%%C
    )
)
7z a QuickBackup%TODAY%.zip *.backup

The same way how an int can be positive or negative. There is no difference. Actually on many platforms unqualified char is signed.

It's not exactly copy and paste but you can import data from Excel using Oracle SQL Developer.

Navigate to the table you want to import the data into and click on the Data tab.

After clicking on the data tab you should notice a drop down that says Actions...

Click Actions... and select the bottom option Import Data...

Then just follow the wizard to select the correct sheet, and columns that you want to import.

EDIT : To view the data tab :

1. Select the SCHEMA where your table is created.(Choose from the Connections tab on the left pane).
2. Right click on the SCHEMA and choose SCHEMA BROWSER.
3. Select your table from the list (by giving your schema).
4. Now you will see the DATA tab.
5. Click on Actions and Import Data...

Depending on devices you might not find sqlite3 command in adb shell. In that case you might want to follow this :

adb shell

$ run-as package.name
$ cd ./databases/
$ ls -l #Find the current permissions - r=4, w=2, x=1
$ chmod 666 ./dbname.db
$ exit
$ exit
adb pull /data/data/package.name/databases/dbname.db ~/Desktop/
adb push ~/Desktop/dbname.db /data/data/package.name/databases/dbname.db
adb shell
$ run-as package.name
$ chmod 660 ./databases/dbname.db #Restore original permissions
$ exit
$ exit

for reference go to https://stackoverflow.com/a/17177091/3758972.

There might be cases when you get "remote object not found" after following above procedure. Then change permission of your database folder to 755 in adb shell.

$ chmod 755 databases/

But please mind that it'll work only on android version < 21.

git rev-parse is an ancillary plumbing command primarily used for manipulation.

One common usage of git rev-parse is to print the SHA1 hashes given a revision specifier. In addition, it has various options to format this output such as --short for printing a shorter unique SHA1.

There are other use cases as well (in scripts and other tools built on top of git) that I've used for:

• --verify to verify that the specified object is a valid git object.
• --git-dir for displaying the abs/relative path of the the .git directory.
• Checking if you're currently within a repository using --is-inside-git-dir or within a work-tree using --is-inside-work-tree
• Checking if the repo is a bare using --is-bare-repository
• Printing SHA1 hashes of branches (--branches), tags (--tags) and the refs can also be filtered based on the remote (using --remote)
• --parse-opt to normalize arguments in a script (kind of similar to getopt) and print an output string that can be used with eval

Massage just implies that it is possible to convert the info from one form into another i.e. a transformation command. These are some quick examples I can think of:

• a branch or tag name into the commit's SHA1 it is pointing to so that it can be passed to a plumbing command which only accepts SHA1 values for the commit.
• a revision range A..B for git log or git diff into the equivalent arguments for the underlying plumbing command as B ^A

VBA subs are no macros. A VBA sub can be a macro, but it is not a must.

The term "macro" is only used for recorded user actions. from these actions a code is generated and stored in a sub. This code is simple and do not provide powerful structures like loops, for example Do .. until, for .. next, while.. do, and others.

The more elegant way is, to design and write your own VBA code without using the macro features!

VBA is a object based and event oriented language. Subs, or bette call it "sub routines", are started by dedicated events. The event can be the pressing of a button or the opening of a workbook and many many other very specific events.

If you focus to VB6 and not to VBA, then you can state, that there is always a main-window or main form. This form is started if you start the compiled executable "xxxx.exe".

In VBA you have nothing like this, but you have a XLSM file wich is started by Excel. You can attach some code to the Workbook_Open event. This event is generated, if you open your desired excel file which is called a workbook. Inside the workbook you have worksheets.

It is useful to get more familiar with the so called object model of excel. The workbook has several events and methods. Also the worksheet has several events and methods.

In the object based model you have objects, that have events and methods. methods are action you can do with a object. events are things that can happen to an object. An objects can contain another objects, and so on. You can create new objects, like sheets or charts.

You mention the certificate is self-signed (by you)? Then you have two choices:

• add the certificate to your trust store (fetching cacert.pem from cURL website won't do anything, since it's self-signed)
• don't bother verifying the certificate: you trust yourself, don't you?

Here's a list of SSL context options in PHP: https://secure.php.net/manual/en/context.ssl.php

Set allow_self_signed if you import your certificate into your trust store, or set verify_peer to false to skip verification.

The reason why we trust a specific certificate is because we trust its issuer. Since your certificate is self-signed, no client will trust the certificate as the signer (you) is not trusted. If you created your own CA when signing the certificate, you can add the CA to your trust store. If your certificate doesn't contain any CA, then you can't expect anyone to connect to your server.

Use chown to change ownership and chmod to change rights.

use the -R option to apply the rights for all files inside of a directory too.

Note that both these commands just work for directories too. The -R option makes them also change the permissions for all files and directories inside of the directory.

For example

sudo chown -R username:group directory

will change ownership (both user and group) of all files and directories inside of directory and directory itself.

sudo chown username:group directory

will only change the permission of the folder directory but will leave the files and folders inside the directory alone.

you need to use sudo to change the ownership from root to yourself.

Edit:

Note that if you use chown user: file (Note the left-out group), it will use the default group for that user.

Also You can change the group ownership of a file or directory with the command:

chgrp group_name file/directory_name

You must be a member of the group to which you are changing ownership to.

You can find group of file as follows

# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file

# chown sujit:friends file

User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.

What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.

But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.

Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.

parseInt(), but be aware that this function is a bit different in the sense that it for example returns 100 for parseInt("100px").

When you see "import: command not found" on the very first import, it is caused by the parser not using the character encoding matching your py file. Especially when you are not using ASCII encoding in your py file.

The way to get it right is to specify the correct encoding on top of your py file to match your file character encoding.

#!/usr/bin/env python3
# -*- coding: utf-8 -*-
import os

There is probably a more efficient solution to your question, but following formula should do the trick:

=SUM(COUNTIFS(J1:J196,"agree",A1:A196,"yes"),COUNTIFS(J1:J196,"agree",A1:A196,"no"))

First add the long press gesture recognizer to the table view:

UILongPressGestureRecognizer *lpgr = [[UILongPressGestureRecognizer alloc] 
  initWithTarget:self action:@selector(handleLongPress:)];
lpgr.minimumPressDuration = 2.0; //seconds
lpgr.delegate = self;
[self.myTableView addGestureRecognizer:lpgr];
[lpgr release];

Then in the gesture handler:

-(void)handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer
{
    CGPoint p = [gestureRecognizer locationInView:self.myTableView];

    NSIndexPath *indexPath = [self.myTableView indexPathForRowAtPoint:p];
    if (indexPath == nil) {
        NSLog(@"long press on table view but not on a row");
    } else if (gestureRecognizer.state == UIGestureRecognizerStateBegan) {
        NSLog(@"long press on table view at row %ld", indexPath.row);
    } else {
        NSLog(@"gestureRecognizer.state = %ld", gestureRecognizer.state);
    }
}

You have to be careful with this so that it doesn't interfere with the user's normal tapping of the cell and also note that handleLongPress may fire multiple times (this will be due to the gesture recognizer state changes).

just use this attribute

not need this line of code:

I needed a quick way to determine if the user connection speed was fast enough to enable/disable some features in a site I’m working on, I made this little script that averages the time it takes to download a single (small) image a number of times, it's working pretty accurately in my tests, being able to clearly distinguish between 3G or Wi-Fi for example, maybe someone can make a more elegant version or even a jQuery plugin.

var dummyImage = new Image();_x000D_
var isConnectedFast = false;_x000D_
_x000D_

  isConnectedFast = (avg <= tThreshold);_x000D_
  /** output */_x000D_
  document.body.appendChild(_x000D_

Easy as that.

Or without JS

<a href="http://yahoo.com" target="_blank">test</a>

Where is x found?

x is not found as you haven't defined it. :-) It could be found in code1 (global) or code3 (local) if you put it there.

code2 (class members) aren't visible to code inside methods of the same class — you would usually access them using self. code4/code5 (loops) live in the same scope as code3, so if you wrote to x in there you would be changing the x instance defined in code3, not making a new x.

Python is statically scoped, so if you pass ‘spam’ to another function spam will still have access to globals in the module it came from (defined in code1), and any other containing scopes (see below). code2 members would again be accessed through self.

lambda is no different to def. If you have a lambda used inside a function, it's the same as defining a nested function. In Python 2.2 onwards, nested scopes are available. In this case you can bind x at any level of function nesting and Python will pick up the innermost instance:

x= 0
def fun1():
    x= 1
    def fun2():
        x= 2
        def fun3():
            return x
        return fun3()
    return fun2()
print fun1(), x

2 0

fun3 sees the instance x from the nearest containing scope, which is the function scope associated with fun2. But the other x instances, defined in fun1 and globally, are not affected.

Before nested_scopes — in Python pre-2.1, and in 2.1 unless you specifically ask for the feature using a from-future-import — fun1 and fun2's scopes are not visible to fun3, so S.Lott's answer holds and you would get the global x:

0 0

I once solved this kind of problem by moving all inlines after the class definition and putting the #include for the other classes just before the inlines in the header file. This way one make sure all definitions+inlines are set prior the inlines are parsed.

Doing like this makes it possible to still have a bunch of inlines in both(or multiple) header files. But it's necessary to have include guards.

Like this

// File: A.h
#ifndef __A_H__
#define __A_H__
class B;
class A
{
    int _val;
    B *_b;
public:
    A(int val);
    void SetB(B *b);
    void Print();
};

// Including class B for inline usage here 
#include "B.h"

inline A::A(int val) : _val(val)
{
}

inline void A::SetB(B *b)
{
    _b = b;
    _b->Print();
}

inline void A::Print()
{
    cout<<"Type:A val="<<_val<<endl;
}

#endif /* __A_H__ */

...and doing the same in B.h

This is what I use in my application:

static void Main()
{
  bool mutexCreated = false;
  System.Threading.Mutex mutex = new System.Threading.Mutex( true, @"Local\slimCODE.slimKEYS.exe", out mutexCreated );

  if( !mutexCreated )
  {
    if( MessageBox.Show(
      "slimKEYS is already running. Hotkeys cannot be shared between different instances. Are you sure you wish to run this second instance?",
      "slimKEYS already running",
      MessageBoxButtons.YesNo,
      MessageBoxIcon.Question ) != DialogResult.Yes )
    {
      mutex.Close();
      return;
    }
  }

  // The usual stuff with Application.Run()

  mutex.Close();
}

This command list the tasks related to the 'node' and have each of them terminated.

kill -9  $( ps -ae | grep 'node' | awk '{print $1}')

As far as I know, we have 2 way for this from given sources like this-

1. arguments.caller

   function whoCalled()
   {
       if (arguments.caller == null)
          console.log('I was called from the global scope.');
       else
          console.log(arguments.caller + ' called me!');
   }
   

2. Function.caller

   function myFunc()
   {
      if (myFunc.caller == null) {
         return 'The function was called from the top!';
      }
      else
      {
         return 'This function\'s caller was ' + myFunc.caller;
       }
   }
   

Think u have your answer :).

Install PIL(Python Image Library) :

then:

from PIL import Image
myImage = Image.open("your_image_here");
myImage.show();

use this code in your DB `

public boolean updatedetails(long rowId,String name, String address)
      {
       ContentValues args = new ContentValues();
       args.put(KEY_ROWID, rowId);          
       args.put(KEY_NAME, name);
       args.put(KEY_ADDRESS, address);
       int i =  mDb.update(DATABASE_TABLE, args, KEY_ROWID + "=" + rowId, null);
    return i > 0;
     }

for updating in your sample.java use this code

  //DB.open();

        try{
              //capture the data from UI
              String name = ((EditText)findViewById(R.id.name)).getText().toString().trim();
              String address =(EditText)findViewById(R.id.address)).getText().toString().trim();

              //open Db
              pdb.open();

              //Save into DBS
              pdb.updatedetails(RowId, name, address);
              Toast.makeText(this, "Modified Successfully", Toast.LENGTH_SHORT).show();
              pdb.close();
              startActivity(new Intent(this, sample.class));
              finish();
        }catch (Exception e) {
            Log.e(TAG_AVV, "errorrrrr !!");
            e.printStackTrace();
        }
    pdb.close();

Update for React Router version 6:

The various answers here are like a timeline of react-router's evolution

Using the latest hooks from react-router v6, this can now be done easily with the useNavigate hook.

import { useNavigate } from 'react-router-dom'      

function MyLinkButton() {
  const navigate = useNavigate()
  return (
      <button onClick={() => navigate("/home")}>
        Go Home
      </button>
  );
}

It's much simpler to do this:

DateTime dt = new DateTime(633896886277130000);

Which gives

dt.ToString() ==> "9/27/2009 10:50:27 PM"

You can format this any way you want by using dt.ToString(MyFormat). Refer to this reference for format strings. "MMMM dd, yyyy" works for what you specified in the question.

Not sure where you get October 1.

Or, change the app to WinForms, use grid and bind DataTable to grid. If it is a demo/sample app.
