Programs & Examples On #Genetic algorithm

There was an competition on codechef.com (great site by the way, monthly programming competitions) where one was supposed to solve an unsolveable sudoku (one should come as close as possible with as few wrong collumns/rows/etc as possible).

What I would do, was to first generate a perfect sudoku and then override the fields, that have been given. From this pretty good basis on I used genetic programming to improve my solution.

I couldn't think of a deterministic approach in this case, because the sudoku was 300x300 and search would've taken too long.

You can simply use subprocess.getoutput(python3 --version)

import subprocess as sp
print(sp.getoutput(python3 --version))

# or however it suits your needs!
py3_version = sp.getoutput(python3 --version)

def check_version(name, version):...

check_version('python3', py3_version)

For more information and ways to do this without depending on the __version__ attribute:

Assign output of os.system to a variable and prevent it from being displayed on the screen

You can also use subprocess.check_output() which raises an error when the subprocess returns anything other than exit code 0:

With google things changes very often: non of the previous answers worked for me.

based on this google training here is how you do it using

fused location provider

this requires Set Up Google Play Services

Activity class

public class GPSTrackerActivity extends AppCompatActivity implements
    GoogleApiClient.ConnectionCallbacks,     
 GoogleApiClient.OnConnectionFailedListener {

private GoogleApiClient mGoogleApiClient;
Location mLastLocation;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if (mGoogleApiClient == null) {
        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
    }

}

protected void onStart() {
    mGoogleApiClient.connect();
    super.onStart();
}

protected void onStop() {
    mGoogleApiClient.disconnect();
    super.onStop();
}

@Override
public void onConnected(Bundle bundle) {
    try {

        mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
                mGoogleApiClient);
        if (mLastLocation != null) {
            Intent intent = new Intent();
            intent.putExtra("Longitude", mLastLocation.getLongitude());
            intent.putExtra("Latitude", mLastLocation.getLatitude());
            setResult(1,intent);
            finish();

        }
    } catch (SecurityException e) {

    }

}

@Override
public void onConnectionSuspended(int i) {

}

@Override
public void onConnectionFailed(ConnectionResult connectionResult) {

}
}

usage

in you activity

 Intent intent = new Intent(context, GPSTrackerActivity.class);
    startActivityForResult(intent,1);

And this method

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == 1){
        Bundle extras = data.getExtras();
        Double longitude = extras.getDouble("Longitude");
        Double latitude = extras.getDouble("Latitude");
    }
}

The best tool I have found is Appshow. Visit http://www.techsmith.com/techsmith-appshow.html (I do not work for them)

Or you can declare a struct type, that contains a character arry(1 string), them create an array of the structs and thus a multi-element array

typedef struct name
{
   char name[100]; // 100 character array
}name;

main()
{
   name yourString[10]; // 10 strings
   printf("Enter something\n:);
   scanf("%s",yourString[0].name);
   scanf("%s",yourString[1].name);
   // maybe put a for loop and a few print ststements to simplify code
   // this is just for example 
 }

One of the advantages of this over any other method is that this allows you to scan directly into the string without having to use strcpy;

public static T GetValueOrDefault<T>(this IDataRecord rdr, int index)
{
    object val = rdr[index];

    if (!(val is DBNull))
        return (T)val;

    return default(T);
}

Just use it like this:

decimal? Quantity = rdr.GetValueOrDefault<decimal?>(1);
string Unit = rdr.GetValueOrDefault<string>(2);

This code worked for me:

var updatedText = text.Normalize(NormalizationForm.FormD)
     .Where(c => CharUnicodeInfo.GetUnicodeCategory(c) != UnicodeCategory.NonSpacingMark)
     .ToArray();

However, please don't do this with names. It's not only an insult to people with umlauts/accents in their name, it can also be dangerously wrong in certain situations (see below). There are alternative writings instead of just removing the accent.

Furthermore, it's simply wrong and dangerous, e.g. if the user has to provide his name exactly how it occurs on the passport.

For example my name is written Zuberbühler and in the machine readable part of my passport you will find Zuberbuehler. By removing the umlaut, the name will not match with either part. This can lead to issues for the users.

You should rather disallow umlauts/accent in an input form for names so the user can write his name correctly without its umlaut or accent.

Practical example, if the web service to apply for ESTA (https://www.application-esta.co.uk/special-characters-and) would use above code instead of transforming umlauts correctly, the ESTA application would either be refused or the traveller will have problems with the American Border Control when entering the States.

Another example would be flight tickets. Assuming you have a flight ticket booking web application, the user provides his name with an accent and your implementation is just removing the accents and then using the airline's web service to book the ticket! Your customer may not be allowed to board since the name does not match to any part of his/her passport.

Expanding on @Shripad's and @Ivan's answer, I would recommend that you use Node.js's standard module.export functionality.

In your file for constants (e.g. constants.js), you'd write constants like this:

const CONST1 = 1;
module.exports.CONST1 = CONST1;

const CONST2 = 2;
module.exports.CONST2 = CONST2;

Then in the file in which you want to use those constants, write the following code:

const {CONST1 , CONST2} = require('./constants.js');

If you've never seen the const { ... } syntax before: that's destructuring assignment.

If you use VS Code and your tests are located on the same level as your project then running and debug your code doesn't work out of the box. What you can do is change your launch.json file:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Python",
            "type": "python",
            "request": "launch",
            "stopOnEntry": false,
            "pythonPath": "${config:python.pythonPath}",
            "program": "${file}",
            "cwd": "${workspaceRoot}",
            "env": {},
            "envFile": "${workspaceRoot}/.env",
            "debugOptions": [
                "WaitOnAbnormalExit",
                "WaitOnNormalExit",
                "RedirectOutput"
            ]
        }    
    ]
}

The key line here is envFile

"envFile": "${workspaceRoot}/.env",

In the root of your project add .env file

Inside of your .env file add path to the root of your project. This will temporarily add

PYTHONPATH=C:\YOUR\PYTHON\PROJECT\ROOT_DIRECTORY

path to your project and you will be able to use debug unit tests from VS Code

Actually it is much more useful use the method that came with the library like this $(".datepicker").datepicker("clearDates");

I recommend you to always take a look at the documentation of the library, here is the one I used for this.

bootstrap-datepicker methods documentation

You can use the DOMSubtreeModified event

$(something).bind('DOMSubtreeModified' ...

But this will fire even if the dimensions don't change, and reassigning the position whenever it fires can take a performance hit. In my experience using this method, checking whether the dimensions have changed is less expensive and so you might consider combining the two.

Or if you are directly altering the div (rather than the div being altered by user input in unpredictable ways, like if it is contentEditable), you can simply fire a custom event whenever you do so.

Downside: IE and Opera don't implement this event.

I had the same problem, and I was using the following plugin for tests:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.9</version>
    <configuration>
        <useFile>true</useFile>
        <includes>
            <include>**/*Tests.java</include>
            <include>**/*Test.java</include>
        </includes>
        <excludes>
            <exclude>**/Abstract*.java</exclude>
        </excludes>
        <junitArtifactName>junit:junit</junitArtifactName>
        <parallel>methods</parallel>
        <threadCount>10</threadCount>
    </configuration>
</plugin>

The test were running fine in the IDE (eclipse sts), but failed when using command mvn test.

After a lot of trial and error, I figured the solution was to remove parallel testing, the following two lines from the plugin configuration above:

    <parallel>methods</parallel>
    <threadCount>10</threadCount>

Hope that this helps someone out!

Edit: I just noted that you are trying to use a gmail address as the from value. This is not going to work, and the ISP is right in overwriting it. If you want to redirect the replies to your outgoing messages, use reply-to.

A workaround for valid addresses that works with many ISPs:

try adding a fifth parameter to your mail() command:

mail($to,$subject,$message,$headers,"-f [email protected]");

In CASSANDRA_HOME/bin/cassandra.bat you would find following configuration

REM JVM Opts we'll use in legacy run or installation
set JAVA_OPTS=-ea^
 -javaagent:"%CASSANDRA_HOME%\lib\jamm-0.3.0.jar"^
 -Xms**2G**^
 -Xmx**2G**^

You can reduce 2G to some smaller number for e.g. 1G or even lesser and it should work.

Same if you are running on unix box, change in .sh file appropriately.

Another method

Cancel local git repository

rm -rf .git

Then; Create git repostory again

git init

Then; Repeat the remote repo connect

git remote add origin REPO_URL

To get the last element, simply use the size of the list as the second parameter. So for example, if you have 35 files, and you want the last five, you would do:

dataList.subList(30, 35);

A guaranteed safe way to do this is:

dataList.subList(Math.max(0, first), Math.min(dataList.size(), last) );

MySQL says:

All integer types can have an optional (nonstandard) attribute UNSIGNED. Unsigned type can be used to permit only nonnegative numbers in a column or when you need a larger upper numeric range for the column. For example, if an INT column is UNSIGNED, the size of the column's range is the same but its endpoints shift from -2147483648 and 2147483647 up to 0 and 4294967295.

When do I use it ?

Ask yourself this question: Will this field ever contain a negative value?
If the answer is no, then you want an UNSIGNED data type.

A common mistake is to use a primary key that is an auto-increment INT starting at zero, yet the type is SIGNED, in that case you’ll never touch any of the negative numbers and you are reducing the range of possible id's to half.

1. Solution

Open Sublime Text console ? paste in opened field:

sublime.packages_path()

? Enter. You get result in console output.

2. Relevance

This answer is relevant for April 2018. In the future, the data of this answer may be obsolete.

3. Not recommended

I'm not recommended @osiris answer. Arguments:

1. In new versions of Sublime Text and/or operating systems (e.g. Sublime Text 4, macOS 14) paths may be changed.
2. It doesn't take portable Sublime Text on Windows. In portable Sublime Text on Windows another path of Packages folder.
3. It less simple.

To put it simply, referring to Stephen Cleary https://stackoverflow.com/a/23051370/267000

your page on creation should create tasks in constructor and you should declare those tasks as class members or put it in your task pool.

Your data are fetched during these tasks, but these tasks should awaited in the code i.e. on some UI manipulations, i.e. Ok Click etc.

I developped such apps in WP, we had a whole bunch of tasks created on start.

Alternatively one can use the setExtremes method also,

yAxis.setExtremes(0, 100);

Or if only one value is needed to be set, just leave other as null

yAxis.setExtremes(null, 100);

There's an input stream decorator, java.security.DigestInputStream, so that you can compute the digest while using the input stream as you normally would, instead of having to make an extra pass over the data.

MessageDigest md = MessageDigest.getInstance("MD5");
try (InputStream is = Files.newInputStream(Paths.get("file.txt"));
     DigestInputStream dis = new DigestInputStream(is, md)) 
{
  /* Read decorated stream (dis) to EOF as normal... */
}
byte[] digest = md.digest();

Anonymous ftp logins are usually the username 'anonymous' with the user's email address as the password. Some servers parse the password to ensure it looks like an email address.

User:  anonymous

You can use the expandable list view explained in API demos to show groups

http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/ExpandableList1.html.

To animate the list items motion, you will have to override the getView method and apply translate animation on each list item. The values for animation depend on the position of each list item. This was something which i tried on a simple list view long time back.

I was having a hell of a time with this as well. I didn't realize that beyond the extra permission you need to append "tel:" onto the string that has the number in it. This is what mine looks like after getting it functional. Hope this helps.

public void onClick(View v) {_x000D_
  Intent intent = new Intent(Intent.ACTION_DIAL);_x000D_
  String temp = "tel:" + phone;_x000D_
  intent.setData(Uri.parse(temp));_x000D_

I was able to install libc6 2.17 in Debian Wheezy by editing the recommendations in perror's answer:

IMPORTANT
You need to exit out of your display manager by pressing CTRL-ALT-F1. Then you can stop x (slim) with sudo /etc/init.d/slim stop

(replace slim with mdm or lightdm or whatever)

Add the following line to the file /etc/apt/sources.list:

deb http://ftp.debian.org/debian experimental main

Should be changed to:

deb http://ftp.debian.org/debian sid main

Then follow the rest of perror's post:

Update your package database:

apt-get update

Install the eglibc package:

apt-get -t sid install libc6-amd64 libc6-dev libc6-dbg

IMPORTANT
After done updating libc6, restart computer, and you should comment out or remove the sid source you just added (deb http://ftp.debian.org/debian sid main), or else you risk upgrading your whole distro to sid.

Hope this helps. It took me a while to figure out.

We can never run out of alternatives of doing the same thing differently, right? I recently found this is pretty handy:

DECLARE
   BAR   VARCHAR2 (200) := '1,2,3';
BEGIN
   FOR FOO IN (    SELECT REGEXP_SUBSTR (BAR,
                                         '[^,]+',
                                         1,
                                         LEVEL)
                             TXT
                     FROM DUAL
               CONNECT BY REGEXP_SUBSTR (BAR,
                                         '[^,]+',
                                         1,
                                         LEVEL)
                             IS NOT NULL)
   LOOP
      DBMS_OUTPUT.PUT_LINE (FOO.TXT);
   END LOOP;
END;

Outputs:

Let's assume you have install target, which is a very common in makefiles. If you do not use .PHONY, and a file named install exists in the same directory as the Makefile, then make install will do nothing. This is because Make interprets the rule to mean "execute such-and-such recipe to create the file named install". Since the file is already there, and its dependencies didn't change, nothing will be done.

However if you make the install target PHONY, it will tell the make tool that the target is fictional, and that make should not expect it to create the actual file. Hence it will not check whether the install file exists, meaning: a) its behavior will not be altered if the file does exist and b) extra stat() will not be called.

Generally all targets in your Makefile which do not produce an output file with the same name as the target name should be PHONY. This typically includes all, install, clean, distclean, and so on.

You can use linq:

var q = from tag in Week orderby Convert.ToDateTime(tag.date) select tag;
List<cTag> Sorted = q.ToList()

If you want the logo to take space, you are probably better of floating it left and then moving down the content using margin, sort of like this:

#logo {
    float: left;
    margin: 0 10px 10px 20px;
}

#content {
    margin: 10px 0 0 10px;
}

or whatever margin you want.

Your question How can I just get the file-names (with paths)

Your syntax example find . -iname "*php" -exec grep -H myString {} \;

My Command suggestion

sudo find /home -name *.php

The output from this command on my Linux OS:

compose-sample-3/html/mail/contact_me.php

As you require the filename with path, enjoy!

Maybe, you can use moment.js which in my opinion is the best JavaScript library for parsing, formatting and working with dates client-side. You could use something like:

var momentDate = moment('1890-09-30T23:59:59+01:16:20', 'YYYY-MM-DDTHH:mm:ss+-HH:mm:ss');_x000D_
var jsDate = momentDate.toDate();_x000D_
_x000D_
// Now, you can run any JavaScript Date method_x000D_
_x000D_
jsDate.toLocaleString();

The advantage of using a library like moment.js is that your code will work perfectly even in legacy browsers like IE 8+.

Here is the documenation about parsing methods: https://momentjs.com/docs/#/parsing/

You can look at the HEAD pointer (stored in .git/HEAD) to see the sha1 of the currently checked-out commit, or it will be of the format ref: refs/heads/foo for example if you have a local ref foo checked out.

EDIT: If you'd like to do this from a shell, git symbolic-ref HEAD will give you the same information.

Simply alter your table, no need to any thing. just run this query on database. ALTER TABLE table_nameCONVERT TO CHARACTER SET utf8

it will definately work.

You can use the start command to do much the same thing as ShellExecute. For example

 start "" http://www.stackoverflow.com

This will launch whatever browser is the default browser, so won't necessarily launch Internet Explorer.

To link to a form you need:

Form2 form2 = new Form2();
        form2.show();

this.hide();

then hide the previous form

Because the people who created Java wanted boolean to mean unambiguously true or false, not 1 or 0.

There's no consensus among languages about how 1 and 0 convert to booleans. C uses any nonzero value to mean true and 0 to mean false, but some UNIX shells do the opposite. Using ints weakens type-checking, because the compiler can't guard against cases where the int value passed in isn't something that should be used in a boolean context.

Using your code, this is how I would do it. I know an answer was chosen, just giving additional options.

data = json.loads('{"lat":444, "lon":555}')
    ret = ''
    for j in data:
        ret = ret+" "+data[j]
return ret

When you use for in this manor you get the key of the object, not the value, so you can get the value, by using the key as an index.

JavaScript has Function-Level variable scope which means you will have to declare your variable outside $(document).ready() function.

Or alternatively to make your variable to have global scope, simply dont use var keyword before it like shown below. However generally this is considered bad practice because it pollutes the global scope but it is up to you to decide.

$(document).ready(function() {
   intro = null; // it is in global scope now

To learn more about it, check out:

• Explaining JavaScript Scope And Closures

While using vim to do it is perfectly possible, why don't you simply use iconv? I mean - loading text editor just to do encoding conversion seems like using too big hammer for too small nail.

Just:

iconv -f utf-16 -t utf-8 file.xml > file.utf8.xml

And you're done.

As of 2020, the most reliable password hashing algorithm in use, most likely to optimise its strength given any hardware, is Argon2id or Argon2i but not its Spring implementation.

The PBKDF2 standard includes the the CPU-greedy/computationally-expensive feature of the block cipher BCRYPT algo, and add its stream cipher capability. PBKDF2 was overwhelmed by the memory exponentially-greedy SCRYPT then by the side-channel-attack-resistant Argon2

Argon2 provides the necessary calibration tool to find optimized strength parameters given a target hashing time and the hardware used.

• Argon2i is specialized in memory greedy hashing
• Argon2d is specialized in CPU greedy hashing
• Argon2id use both methods.

Memory greedy hashing would help against GPU use for cracking.

Spring security/Bouncy Castle implementation is not optimized and relatively week given what attacker could use. cf: Spring doc Argon2 and Scrypt

The currently implementation uses Bouncy castle which does not exploit parallelism/optimizations that password crackers will, so there is an unnecessary asymmetry between attacker and defender.

The most credible implementation in use for java is mkammerer's one,

a wrapper jar/library of the official native implementation written in C.

It is well written and simple to use.

The embedded version provides native builds for Linux, windows and OSX.

As an example, it is used by jpmorganchase in its tessera security project used to secure Quorum, its Ethereum cryptocurency implementation.

Here is an example:

    final char[] password = "a4e9y2tr0ngAnd7on6P১M°RD".toCharArray();
    byte[] salt = new byte[128];
    new SecureRandom().nextBytes(salt);
    final Argon2Advanced argon2 = Argon2Factory.createAdvanced(Argon2Factory.Argon2Types.ARGON2id);
    byte[] hash = argon2.rawHash(10, 1048576, 4, password, salt);

(see tessera)

Declare the lib in your POM:

<dependency>
    <groupId>de.mkammerer</groupId>
    <artifactId>argon2-jvm</artifactId>
    <version>2.7</version>
</dependency>

or with gradle:

compile 'de.mkammerer:argon2-jvm:2.7'

Calibration may be performed using de.mkammerer.argon2.Argon2Helper#findIterations

SCRYPT and Pbkdf2 algorithm might also be calibrated by writing some simple benchmark, but current minimal safe iterations values, will require higher hashing times.

I just replaced the swt.jar in my package with the 64bit version and it worked straight away. No need to recompile the whole package, just replace the swt.jar file and make sure your application manifest includes it.

Bit more detail:

    private void Form1_Load(object sender, EventArgs e)
    {
        Timer MyTimer = new Timer();
        MyTimer.Interval = (45 * 60 * 1000); // 45 mins
        MyTimer.Tick += new EventHandler(MyTimer_Tick);
        MyTimer.Start();
    }

    private void MyTimer_Tick(object sender, EventArgs e)
    {
        MessageBox.Show("The form will now be closed.", "Time Elapsed");
        this.Close();
    }

I was running into this error message because of <></> being returned for some items in the array when instead null needs to be returned.

You can use the pexpect module

Here is a good intro post

child = pexpect.spawn ('/usr/bin/sftp ' + [email protected] )
child.expect ('.* password:')
child.sendline (your_password)
child.expect ('sftp> ')
child.sendline ('dir')
child.expect ('sftp> ')
file_list = child.before
child.sendline ('bye')

I haven't tested this but it should work

A priority queue is an abstract data type that captures the idea of a container whose elements have "priorities" attached to them. An element of highest priority always appears at the front of the queue. If that element is removed, the next highest priority element advances to the front.

The C++ standard library defines a class template priority_queue, with the following operations:

push: Insert an element into the prioity queue.

top: Return (without removing it) a highest priority element from the priority queue.

pop: Remove a highest priority element from the priority queue.

size: Return the number of elements in the priority queue.

empty: Return true or false according to whether the priority queue is empty or not.

The following code snippet shows how to construct two priority queues, one that can contain integers and another one that can contain character strings:

#include <queue>

priority_queue<int> q1;
priority_queue<string> q2;

The following is an example of priority queue usage:

#include <string>
#include <queue>
#include <iostream>

using namespace std;  // This is to make available the names of things defined in the standard library.

int main()
{
    piority_queue<string> pq; // Creates a priority queue pq to store strings, and initializes the queue to be empty.

    pq.push("the quick");
    pq.push("fox");
    pq.push("jumped over");
    pq.push("the lazy dog");

    // The strings are ordered inside the priority queue in lexicographic (dictionary) order:
    // "fox", "jumped over", "the lazy dog", "the quick"
    //  The lowest priority string is "fox", and the highest priority string is "the quick"

    while (!pq.empty()) {
       cout << pq.top() << endl;  // Print highest priority string
       pq.pop();                    // Remmove highest priority string
    }

    return 0;
}

The output of this program is:

the quick
the lazy dog
jumped over
fox

Since a queue follows a priority discipline, the strings are printed from highest to lowest priority.

Sometimes one needs to create a priority queue to contain user defined objects. In this case, the priority queue needs to know the comparison criterion used to determine which objects have the highest priority. This is done by means of a function object belonging to a class that overloads the operator (). The overloaded () acts as < for the purpose of determining priorities. For example, suppose we want to create a priority queue to store Time objects. A Time object has three fields: hours, minutes, seconds:

struct Time {
    int h; 
    int m; 
    int s;
};

class CompareTime {
    public:
    bool operator()(Time& t1, Time& t2) // Returns true if t1 is earlier than t2
    {
       if (t1.h < t2.h) return true;
       if (t1.h == t2.h && t1.m < t2.m) return true;
       if (t1.h == t2.h && t1.m == t2.m && t1.s < t2.s) return true;
       return false;
    }
}

A priority queue to store times according the the above comparison criterion would be defined as follows:

priority_queue<Time, vector<Time>, CompareTime> pq;

Here is a complete program:

#include <iostream>
#include <queue>
#include <iomanip>

using namespace std;

struct Time {
    int h; // >= 0
    int m; // 0-59
    int s; // 0-59
};

class CompareTime {
public:
    bool operator()(Time& t1, Time& t2)
    {
       if (t1.h < t2.h) return true;
       if (t1.h == t2.h && t1.m < t2.m) return true;
       if (t1.h == t2.h && t1.m == t2.m && t1.s < t2.s) return true;
       return false;
    }
};

int main()
{
    priority_queue<Time, vector<Time>, CompareTime> pq;

    // Array of 4 time objects:

    Time t[4] = { {3, 2, 40}, {3, 2, 26}, {5, 16, 13}, {5, 14, 20}};

    for (int i = 0; i < 4; ++i)
       pq.push(t[i]);

    while (! pq.empty()) {
       Time t2 = pq.top();
       cout << setw(3) << t2.h << " " << setw(3) << t2.m << " " <<
       setw(3) << t2.s << endl;
       pq.pop();
    }

    return 0;
}

The program prints the times from latest to earliest:

5  16  13
5  14  20
3   2  40
3   2  26

If we wanted earliest times to have the highest priority, we would redefine CompareTime like this:

class CompareTime {
public:
    bool operator()(Time& t1, Time& t2) // t2 has highest prio than t1 if t2 is earlier than t1
    {
       if (t2.h < t1.h) return true;
       if (t2.h == t1.h && t2.m < t1.m) return true;
       if (t2.h == t1.h && t2.m == t1.m && t2.s < t1.s) return true;
       return false;
    }
};

I just spent an hour on a similar problem. For me the answer turned out to be embarrassingly simple.

(dataGridViewFields.DataSource as DataTable).DefaultView.RowFilter = string.Format("Field = '{0}'", textBoxFilter.Text);

Use List.indexOf(). This will give you the first match when there are multiple duplicates.

Sure, you could use an enum. Would something like the following work?

enum Alignment {
    LEFT,
    RIGHT
}

private static String drawCellValue(int maxCellLength, String cellValue, Alignment alignment) { }

If you wanted to use a boolean, you could rename the align parameter to something like alignLeft. I agree that this implementation is not as clean, but if you don't anticipate a lot of changes and this is not a public interface, it might be a good choice.

Warning This method will not work beyond 5.0, it was a quite dated entry.

Use the class below to change/check the Wifi hotspot setting:

import android.content.*;
import android.net.wifi.*;
import java.lang.reflect.*;

public class ApManager {

//check whether wifi hotspot on or off
public static boolean isApOn(Context context) {
    WifiManager wifimanager = (WifiManager) context.getSystemService(context.WIFI_SERVICE);     
    try {
        Method method = wifimanager.getClass().getDeclaredMethod("isWifiApEnabled");
        method.setAccessible(true);
        return (Boolean) method.invoke(wifimanager);
    }
    catch (Throwable ignored) {}
    return false;
}

// toggle wifi hotspot on or off
public static boolean configApState(Context context) {
    WifiManager wifimanager = (WifiManager) context.getSystemService(context.WIFI_SERVICE);
    WifiConfiguration wificonfiguration = null;
    try {  
        // if WiFi is on, turn it off
        if(isApOn(context)) {               
            wifimanager.setWifiEnabled(false);
        }               
        Method method = wifimanager.getClass().getMethod("setWifiApEnabled", WifiConfiguration.class, boolean.class);                   
        method.invoke(wifimanager, wificonfiguration, !isApOn(context));
        return true;
    } 
    catch (Exception e) {
        e.printStackTrace();
    }       
    return false;
}
} // end of class

You need to add the permissions below to your AndroidMainfest:

<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

Use this standalone ApManager class from anywhere as follows:

ApManager.isApOn(YourActivity.this); // check Ap state :boolean
ApManager.configApState(YourActivity.this); // change Ap state :boolean

Hope this will help someone

You can do:

User.find_or_create_by(first_name: 'Penélope', last_name: 'Lopez')
User.where(first_name: 'Penélope', last_name: 'Lopez').first_or_create

Or to just initialize:

User.find_or_initialize_by(first_name: 'Penélope', last_name: 'Lopez')
User.where(first_name: 'Penélope', last_name: 'Lopez').first_or_initialize

Although it is not an IntelliJ option, you could use a simple Bash command (if your operating system is Linux/Unix). Go to your source directory and type:

find . -type f -name '*.java' | xargs cat | wc -l

It only works till 4000 byte, What if the clob is bigger than 4000 bytes then we use this

declare
v_clob_size clob;

begin

      v_clob_size:= (DBMS_LOB.getlength(v_clob)) / 1024 / 1024;
      DBMS_OUTPUT.put_line('CLOB Size   ' || v_clob_size);   
end;

or

select (DBMS_LOB.getlength(your_column_name))/1024/1024 from your_table

I know this might not be entirely on the subject, but in my experience, I find storing WWW-ness of current URL in a variable useful.

Edit: In addition, please see my comment below, to see what this is getting at.

This is important when determining whether to dispatch Ajax calls with "www", or without:

$.ajax("url" : "www.site.com/script.php", ...

$.ajax("url" : "site.com/script.php", ...

When dispatching an Ajax call the domain name must match that of in the browser's address bar, otherwise you will have Uncaught SecurityError in console.

So I came up with this solution to address the issue:

<?php
    substr($_SERVER['SERVER_NAME'], 0, 3) == "www" ? $WWW = true : $WWW = false;

    if ($WWW) {
        /* We have www.example.com */
    } else {
        /* We have example.com */
    }
?>

Then, based on whether $WWW is true, or false run the proper Ajax call.

I know this might sound trivial, but this is such a common problem that is easy to trip over.

Here's a quick local task to permanently set key/values on /etc/environment (which is system-wide, all users):

- name: populate /etc/environment
  lineinfile:
    dest: "/etc/environment"
    state: present
    regexp: "^{{ item.key }}="
    line: "{{ item.key }}={{ item.value}}"
  with_items: "{{ os_environment }}"

and the vars for it:

os_environment:
  - key: DJANGO_SETTINGS_MODULE 
    value : websec.prod_settings  
  - key: DJANGO_SUPER_USER 
    value : admin

and, yes, if you ssh out and back in, env shows the new environment variables.

If you're just interested in the properties and data types from the database, you can use Model.inspect.

irb(main):001:0> User.inspect
=> "User(id: integer, email: string, encrypted_password: string,
 reset_password_token: string, reset_password_sent_at: datetime,
 remember_created_at: datetime, sign_in_count: integer,
 current_sign_in_at: datetime, last_sign_in_at: datetime,
 current_sign_in_ip: string, last_sign_in_ip: string, created_at: datetime,
 updated_at: datetime)"

Alternatively, having run rake db:create and rake db:migrate for your development environment, the file db/schema.rb will contain the authoritative source for your database structure:

ActiveRecord::Schema.define(version: 20130712162401) do
  create_table "users", force: true do |t|
    t.string   "email",                  default: "", null: false
    t.string   "encrypted_password",     default: "", null: false
    t.string   "reset_password_token"
    t.datetime "reset_password_sent_at"
    t.datetime "remember_created_at"
    t.integer  "sign_in_count",          default: 0
    t.datetime "current_sign_in_at"
    t.datetime "last_sign_in_at"
    t.string   "current_sign_in_ip"
    t.string   "last_sign_in_ip"
    t.datetime "created_at"
    t.datetime "updated_at"
  end
end

If your function have two vector variables and must compute itself on each value of them (as mentioned by @Ari B. Friedman) you can use mapply as follows:

vars1<-c(1,2,3)
vars2<-c(10,20,30)
mult_one<-function(var1,var2)
{
   var1*var2
}
mapply(mult_one,vars1,vars2)

which gives you:

> mapply(mult_one,vars1,vars2)
[1] 10 40 90

Open file/etc/nginx/nginx.conf Add or change client_max_body_size 0;

The only time i will use the 'new' keyowrd for object initialization is in inline arrow function:

() => new Object({ key: value})

since the below code is not valid:

() => { key: value} //  instead of () => { return { key: value};}

.communicate() writes input (there is no input in this case so it just closes subprocess' stdin to indicate to the subprocess that there is no more input), reads all output, and waits for the subprocess to exit.

The exception EOFError is raised in the child process by raw_input() (it expected data but got EOF (no data)).

p.stdout.read() hangs forever because it tries to read all output from the child at the same time as the child waits for input (raw_input()) that causes a deadlock.

To avoid the deadlock you need to read/write asynchronously (e.g., by using threads or select) or to know exactly when and how much to read/write, for example:

from subprocess import PIPE, Popen

p = Popen(["python", "-u", "1st.py"], stdin=PIPE, stdout=PIPE, bufsize=1)
print p.stdout.readline(), # read the first line
for i in range(10): # repeat several times to show that it works
    print >>p.stdin, i # write input
    p.stdin.flush() # not necessary in this case
    print p.stdout.readline(), # read output

print p.communicate("n\n")[0], # signal the child to exit,
                               # read the rest of the output, 
                               # wait for the child to exit

Note: it is a very fragile code if read/write are not in sync; it deadlocks.

Beware of block-buffering issue (here it is solved by using "-u" flag that turns off buffering for stdin, stdout in the child).

bufsize=1 makes the pipes line-buffered on the parent side.

At first, you must specify your path, the path that your *.csv files are in there

path = 'f:\project\dataset'

You can change it based on your system.

then,

use dir function :

files = dir (strcat(path,'\*.csv'))

L = length (files);

for i=1:L
   image{i}=csvread(strcat(path,'\',file(i).name));   
   % process the image in here
end

pwd also can be used.

PHP 8 or newer:

Use the str_contains function.

if (str_contains($str, "."))
{
    echo 'Found it';
}

else
{
    echo 'Not found.';
}

PHP 7 or older:

if (strpos($str, '.') !== FALSE)
{
    echo 'Found it';
}

else
{
    echo 'Not found.';
}

Note that you need to use the !== operator. If you use != or <> and the '.' is found at position 0, the comparison will evaluate to true because 0 is loosely equal to false.

This one-liner works for me in zsh (from @Stephen Haberman's answer)

git fetch; [ $(git rev-parse HEAD) = $(git rev-parse @{u}) ] \
    && echo "Up to date" || echo "Not up to date"

Based on one of the other solutions with a flag to switch between weeks starting on Sunday or Monday

function getWeekForDate($date, $weekStartSunday = false){

    $timestamp = strtotime($date);

    // Week starts on Sunday
    if($weekStartSunday){
        $start = (date("D", $timestamp) == 'Sun') ? date('Y-m-d', $timestamp) : date('Y-m-d', strtotime('Last Sunday', $timestamp));
        $end = (date("D", $timestamp) == 'Sat') ? date('Y-m-d', $timestamp) : date('Y-m-d', strtotime('Next Saturday', $timestamp));
    } else { // Week starts on Monday
        $start = (date("D", $timestamp) == 'Mon') ? date('Y-m-d', $timestamp) : date('Y-m-d', strtotime('Last Monday', $timestamp));
        $end = (date("D", $timestamp) == 'Sun') ? date('Y-m-d', $timestamp) : date('Y-m-d', strtotime('Next Sunday', $timestamp));
    }

    return array('start' => $start, 'end' => $end);
}

NULL isn't a keyword; it's a macro substitution for 0, and comes in stddef.h or cstddef, I believe. You haven't #included an appropriate header file, so g++ sees NULL as a regular variable name, and you haven't declared it.

On Linux, in order to relax access to the document root, you should edit the following file:

/etc/httpd/conf/httpd.conf

And depending on what directory level you want to relax access to, you have to change the directive

AllowOverride None

to

AllowOverride All

So, assuming you want to allow access to files on the /var/www/html directory, you should change the following lines from:

<Directory "/var/www/html">
 AllowOverride None
</Directory>

to

<Directory "/var/www/html">
 AllowOverride All
</Directory>

I ran into the same issue. Daniel Nugent's answer helped a bit (after following his advice HttpResponse was found - but the HttpClient was still missing).

So here is what fixed it for me:

1. (if not already done, commend previous import-statements out)
2. visit http://hc.apache.org/downloads.cgi
3. get the 4.5.1.zip from the binary section
4. unzip it and paste httpcore-4.4.3 & httpclient-4.5.1.jar in project/libs folder
5. right-click the jar and choose Add as library.

Hope it helps.

Here's a nice fun LINQ example.

public static byte[] StringToByteArray(string hex) {
    return Enumerable.Range(0, hex.Length)
                     .Where(x => x % 2 == 0)
                     .Select(x => Convert.ToByte(hex.Substring(x, 2), 16))
                     .ToArray();
}

Actually, we really do not need to import any python library. We can separate the year, month, date using simple SQL. See the below example,

+----------+
|       _c0|
+----------+
|1872-11-30|
|1873-03-08|
|1874-03-07|
|1875-03-06|
|1876-03-04|
|1876-03-25|
|1877-03-03|
|1877-03-05|
|1878-03-02|
|1878-03-23|
|1879-01-18|

I have a date column in my data frame which contains the date, month and year and assume I want to extract only the year from the column.

df.createOrReplaceTempView("res")
sqlDF = spark.sql("SELECT EXTRACT(year from `_c0`) FROM res ")

Here I'm creating a temporary view and store the year values using this single line and the output will be,

+-----------------------+
|year(CAST(_c0 AS DATE))|
+-----------------------+
|                   1872|
|                   1873|
|                   1874|
|                   1875|
|                   1876|
|                   1876|
|                   1877|
|                   1877|
|                   1878|
|                   1878|
|                   1879|
|                   1879|
|                   1879|

You can do that with a single statement and a subquery in nearly all relational databases.

INSERT INTO targetTable(field1) 
SELECT field1
FROM myTable
WHERE NOT(field1 IN (SELECT field1 FROM targetTable))

Certain relational databases have improved syntax for the above, since what you describe is a fairly common task. SQL Server has a MERGE syntax with all kinds of options, and MySQL has optional INSERT OR IGNORE syntax.

Edit: SmallSQL's documentation is fairly sparse as to which parts of the SQL standard it implements. It may not implement subqueries, and as such you may be unable to follow the advice above, or anywhere else, if you need to stick with SmallSQL.

try a generic list instead of array

Some comments on your code

• why would you want to have 2 for loops like for(i='A';i<='Z';i++), if you can check this with a simple if statement ... you loop over a whole range while you can simply check whether it is contained in that range
• even when you found your answer (for example when input is A you will have your result the first time you enter the first loop) you still loop over all the rest
• your System.out.println("Lowercase"); statement (and the uppercase statement) are placed in the wrong loop
• If you are allowed to use it, I suggest to look at the Character class which has for example nice isUpperCase and isLowerCase methods

I leave the rest up to you since it is homework

Here is how we fixed this.

Step 1: Open Keychain access, delete "Apple world wide Developer relations certification authority" (which expires on 14th Feb 2016) from both "Login" and "System" sections. If you can't find it, use “Show Expired Certificates” in the View menu.

Step 2: Download this and add it to Keychain access -> Certificates (which expires on 8th Feb 2023).

Step 3: Everything should be back to normal and working now.

Reference: Apple Worldwide Developer Relations Intermediate Certificate Expiration

One example more :)

double a = 1.00

if(floor(a) == a) {
   // a is an integer
} else {
   //a is not an integer.
}

In this example, ceil can be used and have the exact same effect.

double[] array = new double[1048576];

...

By default order is ascending

To reverse the order

Arrays.sort(array,Collections.reverseOrder());

Try doing it from the command like:

cat dump.sql | sqlite3 database.db

This will obviously only work with SQL statements in dump.sql. I'm not sure how to import a CSV.

I use the AbsoluteUri and you can get it like this:

string myURI = Request.Url.AbsoluteUri;
 if (!WebSecurity.IsAuthenticated) {
        Response.Redirect("~/Login?returnUrl="
            + Request.Url.AbsoluteUri );

Then after you login:

var returnUrl = Request.QueryString["returnUrl"];
 if(WebSecurity.Login(username,password,true)){
                Context.RedirectLocal(returnUrl);

It works well for me.

@RequestMapping is a class level

@GetMapping is a method-level

With sprint Spring 4.3. and up things have changed. Now you can use @GetMapping on the method that will handle the http request. The class-level @RequestMapping specification is refined with the (method-level)@GetMapping annotation

Here is an example:

@Slf4j
@Controller
@RequestMapping("/orders")/* The @Request-Mapping annotation, when applied
                            at the class level, specifies the kind of requests 
                            that this controller handles*/  

public class OrderController {

@GetMapping("/current")/*@GetMapping paired with the classlevel
                        @RequestMapping, specifies that when an 
                        HTTP GET request is received for /order, 
                        orderForm() will be called to handle the request..*/

public String orderForm(Model model) {

model.addAttribute("order", new Order());

return "orderForm";
}
}

Prior to Spring 4.3, it was @RequestMapping(method=RequestMethod.GET)

Extra reading from a book authored by Craig Walls

The problem is that the small figure region 2 created by your layout() call is not sufficiently large enough to contain just the default margins, let alone a plot.

More generally, you get this error if the size of the plotting region on the device is not large enough to actually do any plotting. For the OP's case the issue was having too small a plotting device to contain all the subplots and their margins and leave a large enough plotting region to draw in.

RStudio users can encounter this error if the Plot tab is too small to leave enough room to contain the margins, plotting region etc. This is because the physical size of that pane is the size of the graphics device. These are not independent issues; the plot pane in RStudio is just another plotting device, like png(), pdf(), windows(), and X11().

Solutions include:

1. reducing the size of the margins; this might help especially if you are trying, as in the case of the OP, to draw several plots on the same device.

2. increasing the physical dimensions of the device, either in the call to the device (e.g. png(), pdf(), etc) or by resizing the window / pane containing the device

3. reducing the size of text on the plot as that can control the size of margins etc.

Reduce the size of the margins

Before the line causing the problem try:

par(mar = rep(2, 4))

then plot the second image

image(as.matrix(leg),col=cx,axes=T)

You'll need to play around with the size of the margins on the par() call I show to get this right.

Increase the size of the device

You may also need to increase the size of the actual device onto which you are plotting.

A final tip, save the par() defaults before changing them, so change your existing par() call to:

op <- par(oma=c(5,7,1,1))

then at the end of plotting do

par(op)

Well, I'd say use the DIV instead of table as it would be much easier (but there's nothing wrong with using tables).

My approach would be to use jQuery.ajax and request more data from server and that way, the selected DIV (or TD if you use table) will automatically expand based on requested content.

That way, it saves bandwidth and makes it go faster as you don't load all content at once. It loads only when it's selected.

You have to put the selector.xml file in the drwable folder. Then write: android:background="@drawable/selector". This takes care of the pressed and focussed states.

If you use jqueryui (or another toolset) this is the way you do it

This should work with any div or screen size:

.center-screen {_x000D_
  display: flex;_x000D_
  flex-direction: column;_x000D_
  justify-content: center;_x000D_
  align-items: center;_x000D_
  text-align: center;_x000D_
  min-height: 100vh;_x000D_
}

 <html>_x000D_
 <head>_x000D_
 </head>_x000D_
 <body>_x000D_
 <div class="center-screen">_x000D_
 I'm in the center_x000D_
 </div>_x000D_
 </body>_x000D_
 </html>

See more details about flex here. This should work on most of the browsers, see compatibility matrix here.

Update: If you don't want the scroll bar, make min-height smaller, for example min-height: 95vh;

My solution was the following:

document.getElementById("agent_details").scrollIntoView();

<meta http-equiv="pragma" content="no-cache" />

What do you mean by "initialize an array to zero"? Arrays don't contain "zero" -- they can contain "zero elements", which is the same as "an empty list". Or, you could have an array with one element, where that element is a zero: my @array = (0);

my @array = (); should work just fine -- it allocates a new array called @array, and then assigns it the empty list, (). Note that this is identical to simply saying my @array;, since the initial value of a new array is the empty list anyway.

Are you sure you are getting an error from this line, and not somewhere else in your code? Ensure you have use strict; use warnings; in your module or script, and check the line number of the error you get. (Posting some contextual code here might help, too.)

This depends on what content do you have. You need to initialize your requestMessage.Content property with new HttpContent. For example:

...
// Add request body
if (isPostRequest)
{
    requestMessage.Content = new ByteArrayContent(content);
}
...

where content is your encoded content. You also should include correct Content-type header.

UPDATE:

Oh, it can be even nicer (from this answer):

requestMessage.Content = new StringContent("{\"name\":\"John Doe\",\"age\":33}", Encoding.UTF8, "application/json");

Try This

Just go to your Manifest file. and You have define the label for each activity in your manifest file.

<activity
        android:name=".Search_Video"
        android:label="@string/app_name"
        android:screenOrientation="portrait">
    </activity>

here change

android:label="@string/your_title"

In Win 7, navigate to the directory where your text files are. On the command prompt use:

copy *.txt combined.txt

Where combined.txt is the name of the newly created text file.

If you want to check for local files first do:

@font-face {
font-family: 'Green Sans Web';
src:
    local('Green Web'),
    local('GreenWeb-Regular'),
    url('GreenWeb.ttf');
}

There is a more elaborate description of what to do here.

You could always use something like mktime to create a known time (midnight, last night) and use difftime to get a double-precision time difference between the two. For a platform-independant solution, unless you go digging into the details of your libraries, you're not going to do much better than that. According to the C spec, the definition of time_t is implementation-defined (meaning that each implementation of the library can define it however they like, as long as library functions with use it behave according to the spec.)

That being said, the size of time_t on my linux machine is 8 bytes, which suggests a long int or a double. So I did:

int main()
{
    for(;;)
    {
        printf ("%ld\n", time(NULL));
        printf ("%f\n", time(NULL));
        sleep(1);
    }
    return 0;
}

The time given by the %ld increased by one each step and the float printed 0.000 each time. If you're hell-bent on using printf to display time_ts, your best bet is to try your own such experiment and see how it work out on your platform and with your compiler.

Following solution is clean and works perfectly.

1. Download Elevate zip file from https://www.winability.com/download/Elevate.zip

2. Inside zip you should find two files: Elevate.exe and Elevate64.exe. (The latter is a native 64-bit compilation, if you require that, although the regular 32-bit version, Elevate.exe, should work fine with both the 32- and 64-bit versions of Windows)

3. Copy the file Elevate.exe into a folder where Windows can always find it (such as C:/Windows). Or you better you can copy in same folder where you are planning to keep your bat file.

4. To use it in a batch file, just prepend the command you want to execute as administrator with the elevate command, like this:

 elevate net start service ...

Regarding Aryo's answer: In my case I had to use the full URL of my local Git repository to push the file. First I removed all the files in the current directory and created README added it.

Added some more. Then I committed those files and at last pushed them, giving a proper URL to the repository. Here yourrepository is the name of the repository on the server.

rm -rf *

touch README
git add README
touch file1 file2
git add file1 file2

git commit -m "reinitialized files"
git push git@localhost:yourrepository.git master --force

If i understand correctly, can't you simply use:

foreach($arr as $key=>$value)
{
  echo $key;
}

See PHP manual

You can do it with:

UPDATE mytable SET Total = Pieces * Price;

This same error I have faced in case of getting Notification in latest Android devices 9 and 10.

It depends on Launch mode how you are handling it. Use below code:- android:launchMode="singleTask"

Add this flag with Intent:- intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

Use parseLong(), e.g.:

long lg = lg.parseLong("123456789123456789");

To position horizontally center you can say width: 50%; margin: auto;. As far as I know, that's cross browser. For vertical alignment you can try vertical-align:middle;, but it may only work in relation to text. It's worth a try though.

strcat has the declaration:

char *strcat(char *dest, const char *src)

It expects 2 strings. While this compiles:

char str[1024] = "Hello World";
char tmp = '.';

strcat(str, tmp);

It will cause bad memory issues because strcat is looking for a null terminated cstring. You can do this:

char str[1024] = "Hello World";
char tmp[2] = ".";

strcat(str, tmp);

Live example.

If you really want to append a char you will need to make your own function. Something like this:

void append(char* s, char c) {
        int len = strlen(s);
        s[len] = c;
        s[len+1] = '\0';
}

append(str, tmp)

Of course you may also want to check your string size etc to make it memory safe.

As an alternate streaming approach:

• dump each col into a file
• use python or unix paste command to rejoin on tab, csv, whatever.

Both steps should handle steaming just fine.

Pitfalls:

• if you have 1000s of columns, you might run into the unix file handle limit!

Further to everyone else's answer, you should note that the parameters are optional in C# if your application does not use command line arguments.

This code is perfectly valid:

internal static Program
{
    private static void Main()
    {
        // Get on with it, without any arguments...
    }
}

All these answers and there is STILL just one missing. When you create your auth credential in the Google API section of the dev console, make sure (especially if it is your first one) that you have clicked on the 'consent screen' option. If you don't have the 'title' and any other required field filled out the call will fail with this option.

Your "array" as shown is invalid JavaScript syntax. Curly brackets {} are for objects with property name/value pairs, but square brackets [] are for arrays - like so:

someArray = [{name:"Kristian", lines:"2,5,10"}, {name:"John", lines:"1,19,26,96"}];

In that case, you can use the .splice() method to remove an item. To remove the first item (index 0), say:

someArray.splice(0,1);

// someArray = [{name:"John", lines:"1,19,26,96"}];

If you don't know the index but want to search through the array to find the item with name "Kristian" to remove you could to this:

for (var i =0; i < someArray.length; i++)
   if (someArray[i].name === "Kristian") {
      someArray.splice(i,1);
      break;
   }

EDIT: I just noticed your question is tagged with "jQuery", so you could try the $.grep() method:

someArray = $.grep(someArray,
                   function(o,i) { return o.name === "Kristian"; },
                   true);

@Rob Sedgwick's answer gave me a pointer, However, in my case my app was a Spring Boot Application. So I just added exclusions in my Security Config for the paths to the concerned files...

NOTE - This solution is SpringBoot-based... What you may need to do might differ based on what programming language you are using and/or what framework you are utilizing

However the point to note is;

Essentially the problem can be caused when every request, including those for static content are being authenticated.

So let's say some paths to my static content which were causing the errors are as follows;

A path called "plugins"

http://localhost:8080/plugins/styles/css/file-1.css

http://localhost:8080/plugins/styles/css/file-2.css

http://localhost:8080/plugins/js/script-file.js

And a path called "pages"

http://localhost:8080/pages/styles/css/style-1.css

http://localhost:8080/pages/styles/css/style-2.css

http://localhost:8080/pages/js/scripts.js

Then I just add the exclusions as follows in my Spring Boot Security Config;

@Configuration
@EnableGlobalMethodSecurity(prePostEnabled = true)
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
            .antMatchers(<comma separated list of other permitted paths>, "/plugins/**", "/pages/**").permitAll()
            // other antMatchers can follow here
    }

}

Cheers!

Before you set your routes, add the code:

app.all('*', function(req, res, next) {
    setTimeout(function() {
        next();
    }, 120000); // 120 seconds
});

You can store images in MySQL as blobs. However, this is problematic for a couple of reasons:

• The images can be harder to manipulate: you must first retrieve them from the database before bulk operations can be performed.
• Except in very rare cases where the entire database is stored in RAM, MySQL databases are ultimately stored on disk. This means that your DB images are converted to blobs, inserted into a database, and then stored on disk; you can save a lot of overhead by simply storing them on disk.

Instead, consider updating your table to add an image_path field. For example:

ALTER TABLE `your_table`
ADD COLUMN `image_path` varchar(1024)

Then store your images on disk, and update the table with the image path. When you need to use the images, retrieve them from disk using the path specified.

An advantageous side-effect of this approach is that the images do not necessarily be stored on disk; you could just as easily store a URL instead of an image path, and retrieve images from any internet-connected location.

DTO is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.

• DTO should only contain private fields for your data, getters, setters, and constructors.
• DTO is not recommended to add business logic methods to such classes, but it is OK to add some util methods.

DAO is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).

Here is an example of how the DAO and DTO interfaces would look like:

interface PersonDTO {
    String getName();
    void setName(String name);
    //.....
}

interface PersonDAO {
    PersonDTO findById(long id);
    void save(PersonDTO person);
    //.....
}

The MVC is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.

As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.

The first answer is good for understanding how it works. But I wanted to understand how I should be using it in practice.

SUMMARY

• for moderately imbalanced data WITHOUT noise, there is not much of a difference in applying class weights
• for moderately imbalanced data WITH noise and strongly imbalanced, it is better to apply class weights
• param class_weight="balanced" works decent in the absence of you wanting to optimize manually
• with class_weight="balanced" you capture more true events (higher TRUE recall) but also you are more likely to get false alerts (lower TRUE precision)
  • as a result, the total % TRUE might be higher than actual because of all the false positives
  • AUC might misguide you here if the false alarms are an issue
• no need to change decision threshold to the imbalance %, even for strong imbalance, ok to keep 0.5 (or somewhere around that depending on what you need)

NB

The result might differ when using RF or GBM. sklearn does not have class_weight="balanced" for GBM but lightgbm has LGBMClassifier(is_unbalance=False)

Java 13 added a method which does this: String#translateEscapes.

It was a preview feature in Java 13 and 14, but was promoted to a full feature in Java 15.

I've found that there are some files that may affect the $PATH variable in macOS (works for me, 10.11 El Capitan), listed below:

1. As the top voted answer said, vi /etc/paths, which is recommended from my point of view.

2. Also don't forget the /etc/paths.d directory, which contains files may affect the $PATH variable, set the git and mono-command path in my case. You can ls -l /etc/paths.d to list items and rm /etc/paths.d/path_you_dislike to remove items.

3. If you're using a "bash" environment (the default Terminal.app, for example), you should check out ~/.bash_profile or ~/.bashrc. There may be not that file yet, but these two files have effects on the $PATH.

4. If you're using a "zsh" environment (Oh-My-Zsh, for example), you should check out ~./zshrc instead of ~/.bash* thing.

And don't forget to restart all the terminal windows, then echo $PATH. The $PATH string will be PATH_SET_IN_3&4:PATH_SET_IN_1:PATH_SET_IN_2.

Noticed that the first two ways (/etc/paths and /etc/path.d) is in / directory which will affect all the accounts in your computer while the last two ways (~/.bash* or ~/.zsh*) is in ~/ directory (aka, /Users/yourusername/) which will only affect your account settings.

This answer is specific to MAC users.

The default VIM available with MAC does not come with clipboard option enabled. You need that option to access the system clipboard.

To check if your vim has that option enabled use the below command

vim --version

In the result, you should have +clipboard. If it is -clipboard, then your VIM does NOT have the option to access the system clipboard.

You need to MAKE and install your VIM with the option you need. Following are the commands.

# Create the directories you need
$ sudo mkdir -p /opt/local/bin
# Download, compile, and install the latest Vim
$ cd ~
$ git clone https://github.com/vim/vim.git
$ cd vim
$ ./configure --prefix=/opt/local
$ make
$ sudo make install
# Add the binary to your path, ahead of /usr/bin
$ echo 'PATH=/opt/local/bin:$PATH' >> ~/.bash_profile
# Reload bash_profile so the changes take effect in this window
$ source ~/.bash_profile"

The above will install the latest VIM with the option +clipboard enabled.

Now you need to set the system clipboard. Append the following line to ~/.vimrc

set clipboard=unnamed

Now you can yank text to system clipboard. Below steps explains how to yank.

1. In vim command mode press v, this will switch you to VISUAL mode.
2. Move the cursor around to select the text or lines you need to copy.
3. Press y, this will copy the selected text to clipboard.
4. Go to any external application and CMD + v to paste.

I use MACBook Pro with macOS Mojave and the above works in it.

I had the same problem.

It really depends on the IE versions ... I found this excellent resource that is up to date from IE6-10:

CSS hack for Internet Explorer 6

It is called the Star HTML Hack and looks as follows:

• html .color {color: #F00;} This hack uses fully valid CSS.

CSS hack for Internet Explorer 7

It is called the Star Plus Hack.

*:first-child+html .color {color: #F00;} Or a shorter version:

*+html .color {color: #F00;} Like the star HTML hack, this uses valid CSS.

CSS hack for Internet Explorer 8

@media \0screen { .color {color: #F00;} } This hacks does not use valid CSS.

CSS hack for Internet Explorer 9

:root .color {color: #F00\9;} This hacks also does not use valid CSS.

Added 2013.02.04: Unfortunately IE10 understands this hack.

CSS hack for Internet Explorer 10

@media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) { .color {color: #F00;} } This hacks also does not use valid CSS.

I implemented UICollectionViewDelegateFlowLayout on my UICollectionViewController and override the method responsible for determining the size of the Cell. I then took the screen width and divided it with my column requirement. For example, I wanted to have 3 columns on each screen size. So here's what my code looks like -

- (CGSize)collectionView:(UICollectionView *)collectionView
                  layout:(UICollectionViewLayout *)collectionViewLayout
  sizeForItemAtIndexPath:(NSIndexPath *)indexPath
{
    CGRect screenRect = [[UIScreen mainScreen] bounds];
    CGFloat screenWidth = screenRect.size.width;
    float cellWidth = screenWidth / 3.0; //Replace the divisor with the column count requirement. Make sure to have it in float.
    CGSize size = CGSizeMake(cellWidth, cellWidth);

    return size;
}

According to the documentation, there needs to be a top level layout set.

A top level layout is necessary to ensure that your widgets will resize correctly when its window is resized. To check if you have set a top level layout, preview your widget and attempt to resize the window by dragging the size grip.

You can set one by clearing the selection and right clicking on the form itself and choosing one of the layouts available in the context menu.

You can try the following:

function InitOverviewDataTable() {
    oOverviewTable = $('#HelpdeskOverview').dataTable({
        "bPaginate": true,
        "bJQueryUI": true, // ThemeRoller-stöd
        "bLengthChange": false,
        "bFilter": false,
        "bSort": false,
        "bInfo": true,
        "bAutoWidth": true,
        "bProcessing": true,
        "iDisplayLength": 10,
        "sAjaxSource": '/Helpdesk/ActiveCases/noacceptancetest'
    });
}

function RefreshTable(tableId, urlData) {
    $.getJSON(urlData, null, function(json) {
        table = $(tableId).dataTable();
        oSettings = table.fnSettings();

        table.fnClearTable(this);

        for (var i = 0; i < json.aaData.length; i++) {
            table.oApi._fnAddData(oSettings, json.aaData[i]);
        }

        oSettings.aiDisplay = oSettings.aiDisplayMaster.slice();
        table.fnDraw();
    });
}
// Edited by Prasad
function AutoReload() {
    RefreshTable('#HelpdeskOverview', '/Helpdesk/ActiveCases/noacceptancetest');

    setTimeout(function() {
        AutoReload();
    }, 30000);
}

$(document).ready(function() {
    InitOverviewDataTable();
    setTimeout(function() {
        AutoReload();
    }, 30000);
});

You can do the following:

    import java.util.Scanner;

    public class Test {

            public static void main(String[] args) {

            int arr[];
            Scanner scan = new Scanner(System.in);
            // If you want to take 5 numbers for user and store it in an int array
            for(int i=0; i<5; i++) {
                System.out.print("Enter number " + (i+1) + ": ");
                arr[i] = scan.nextInt();    // Taking user input
            }

            // For printing those numbers
            for(int i=0; i<5; i++) 
                System.out.println("Number " + (i+1) + ": " + arr[i]);
        }
    }

presentViewController shows a view controller. It doesn't return a view controller. If you're not using a UINavigationController, you're probably looking for presentedViewController and you'll need to start at the root and iterate down through the presented views.

if var topController = UIApplication.sharedApplication().keyWindow?.rootViewController {
    while let presentedViewController = topController.presentedViewController {
        topController = presentedViewController
    }

    // topController should now be your topmost view controller
}

For Swift 3+:

if var topController = UIApplication.shared.keyWindow?.rootViewController {
    while let presentedViewController = topController.presentedViewController {
        topController = presentedViewController
    }

    // topController should now be your topmost view controller
}

For iOS 13+

let keyWindow = UIApplication.shared.windows.filter {$0.isKeyWindow}.first

if var topController = keyWindow?.rootViewController {
    while let presentedViewController = topController.presentedViewController {
        topController = presentedViewController
    }

// topController should now be your topmost view controller
}

You could also use the php native funcion get_browser()

IMPORTANT NOTE: You should have a browscap.ini file.

All I had to do was to change the port numbers.

1. Open Eclipse

2. Go to Servers panel

3. Right click on Tomcat Server select Open, Overview window will appear.

4. Open the Portstab. You will get the following:

   • Tomcat adminport

   • HTTP/1.1

   • AJP/1.3

5. I changed the port number of HTTP/1.1 (i.e. to 8081)

6. You might have to also change the port of Tomcat adminport (i.e. to 8006) and of AJP/1.3 (i.e. to 8010).

7. Access your app in the browser at http://localhost:8081/...

You have name spaces so you can have globally unique elements. However, 99% of the time this doesn't really matter, but when you put it in the perspective of The Semantic Web, it starts to become important.

For example, you could make an XML mash-up of different schemes just by using the appropriate xmlns. For example, mash up friend of a friend with vCard, etc.

I also recommend PyInstaller for better backward compatibility such as Python 2.3 - 2.7.

For py2exe, you have to have Python 2.6.

    $('[class*="tag"]').live('click', function() {
      if ($(this).hasClass('clickedTag')){
         // code here
      } else {
         // and here
      }
   });

For Windows 10 (follow up on @slckin answer), this can be set through the command line with:

setx PYTHONHOME "C:\Python27"
setx PYTHONPATH "C:\Python27\Lib"
setx PATH "%PYTHONHOME%;%PATH%"

If you mean "non-alphanumeric characters", try to use this:

var reg =/[^a-zA-Z0-9]/g      //[^abc]

from command console, if you get this error you can avoid it by typing

c:\> sqlplus /nolog

then you can connect

SQL> conn user/pass @host:port/service

I had a similar issue with an Angular project. In my polyfills.ts I had to add both:

    import "core-js/es7/array";
    import "core-js/es7/object";

In addition to enabling all the other IE 11 defaults. (See comments in polyfills.ts if using angular)

After adding these imports the error went away and my Object data populated as intended.

What about %n using a formatter like String.format()?:

String s = String.format("I%nam%na%nboy");

As this answer says, its available from java 1.5 and is another way to System.getProperty("line.separator") or System.lineSeparator() and, like this two, is OS independent.

I encountered this issue recently too, and I later found out it was because I didn't put a space between and and (. This was the error

@media screen and(max-width:768px){
}

Then I changed it to this to correct it

@media screen and (max-width:768px){
}

Installing ASP.NET Core Runtime Hosting Bundle solved the issue for me. Source: 500.19 Internal Server Error (0x8007000d)

If you just want to do a literal replace in java, use Pattern.quote(string) to escape any string to a literal.

myString.replaceAll(Pattern.quote(matchingStr), replacementStr)

most editors support save as ‘Unicode’ encoding actually.

This is an unfortunate misnaming perpetrated by Windows.

Because Windows uses UTF-16LE encoding internally as the memory storage format for Unicode strings, it considers this to be the natural encoding of Unicode text. In the Windows world, there are ANSI strings (the system codepage on the current machine, subject to total unportability) and there are Unicode strings (stored internally as UTF-16LE).

This was all devised in the early days of Unicode, before we realised that UCS-2 wasn't enough, and before UTF-8 was invented. This is why Windows's support for UTF-8 is all-round poor.

This misguided naming scheme became part of the user interface. A text editor that uses Windows's encoding support to provide a range of encodings will automatically and inappropriately describe UTF-16LE as “Unicode”, and UTF-16BE, if provided, as “Unicode big-endian”.

(Other editors that do encodings themselves, like Notepad++, don't have this problem.)

If it makes you feel any better about it, ‘ANSI’ strings aren't based on any ANSI standard, either.

The usual pattern is EXISTS(subselect):

BEGIN
  IF EXISTS(SELECT name
              FROM test_table t
             WHERE t.id = x
               AND t.name = 'test')
  THEN
     ---
  ELSE
     ---
  END IF;

This pattern is used in PL/SQL, PL/pgSQL, SQL/PSM, ...

An old thread, nonetheless someone may benefit from this:

li:not(:last-child)::after { content: ","; }
li:last-child::after { content: "."; }

This should work in CSS3 and [untested] CSS2.

These steps worked for me on several Systems using Ubuntu 16.04, Apache 2.4, MariaDB, PDO

1. log into MYSQL as root

   mysql -u root
   

2. Grant privileges. To a new user execute:

   CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password';
   GRANT ALL PRIVILEGES ON *.* TO 'newuser'@'localhost';
   FLUSH PRIVILEGES;
   

   UPDATE for Google Cloud Instances

   MySQL on Google Cloud seem to require an alternate command (mind the backticks).

   GRANT ALL PRIVILEGES ON `%`.* TO 'newuser'@'localhost';
   

3. bind to all addresses:

   The easiest way is to comment out the line in your /etc/mysql/mariadb.conf.d/50-server.cnf or /etc/mysql/mysql.conf.d/mysqld.cnf file, depending on what system you are running:

   #bind-address = 127.0.0.1 
   

4. exit mysql and restart mysql

   exit
   service mysql restart
   

By default it binds only to localhost, but if you comment the line it binds to all interfaces it finds. Commenting out the line is equivalent to bind-address=*.

To check the binding of mysql service execute as root:

netstat -tupan | grep mysql

SQL Server 2016 SP2 CU6 and SQL Server 2017 CU12 introduced trace flag 460 in order to return the details of truncation warnings. You can enable it at the query level or at the server level.

Query level

INSERT INTO dbo.TEST (ColumnTest)
VALUES (‘Test truncation warnings’)
OPTION (QUERYTRACEON 460);
GO

Server Level

DBCC TRACEON(460, -1);
GO

From SQL Server 2019 you can enable it at database level:

ALTER DATABASE SCOPED CONFIGURATION 
SET VERBOSE_TRUNCATION_WARNINGS = ON;

The old output message is:

Msg 8152, Level 16, State 30, Line 13
String or binary data would be truncated.
The statement has been terminated.

The new output message is:

Msg 2628, Level 16, State 1, Line 30
String or binary data would be truncated in table 'DbTest.dbo.TEST', column 'ColumnTest'. Truncated value: ‘Test truncation warnings‘'.

In a future SQL Server 2019 release, message 2628 will replace message 8152 by default.

SQL

SQL is used to communicate with a database, it is the standard language for relational database management systems.

In detail Structured Query Language is a special-purpose programming language designed for managing data held in a relational database management system (RDBMS), or for stream processing in a relational data stream management system (RDSMS).

Originally based upon relational algebra and tuple relational calculus, SQL consists of a data definition language and a data manipulation language. The scope of SQL includes data insert, query, update and delete, schema creation and modification, and data access control. Although SQL is often described as, and to a great extent is, a declarative language (4GL), it also includes procedural elements.

PL/SQL

PL/SQL is a combination of SQL along with the procedural features of programming languages. It was developed by Oracle Corporation

Specialities of PL/SQL

• completely portable, high-performance transaction-processing language.
• provides a built-in interpreted and OS independent programming environment.
• directly be called from the command-line SQL*Plus interface.
• Direct call can also be made from external programming language calls to database.
• general syntax is based on that of ADA and Pascal programming language.
• Apart from Oracle, it is available in TimesTen in-memory database and IBM DB2.

T-SQL

Short for Transaction-SQL, an extended form of SQL that adds declared variables, transaction control, error and exceptionhandling and row processing to SQL

The Structured Query Language or SQL is a programming language that focuses on managing relational databases. SQL has its own limitations which spurred the software giant Microsoft to build on top of SQL with their own extensions to enhance the functionality of SQL. Microsoft added code to SQL and called it Transact-SQL or T-SQL. Keep in mind that T-SQL is proprietary and is under the control of Microsoft while SQL, although developed by IBM, is already an open format.

T-SQL adds a number of features that are not available in SQL.

This includes procedural programming elements and a local variable to provide more flexible control of how the application flows. A number of functions were also added to T-SQL to make it more powerful; functions for mathematical operations, string operations, date and time processing, and the like. These additions make T-SQL comply with the Turing completeness test, a test that determines the universality of a computing language. SQL is not Turing complete and is very limited in the scope of what it can do.

Another significant difference between T-SQL and SQL is the changes done to the DELETE and UPDATE commands that are already available in SQL. With T-SQL, the DELETE and UPDATE commands both allow the inclusion of a FROM clause which allows the use of JOINs. This simplifies the filtering of records to easily pick out the entries that match a certain criteria unlike with SQL where it can be a bit more complicated.

Choosing between T-SQL and SQL is all up to the user. Still, using T-SQL is still better when you are dealing with Microsoft SQL Server installations. This is because T-SQL is also from Microsoft, and using the two together maximizes compatibility. SQL is preferred by people who have multiple backends.

What I am wondering is if there is any strange way to make this check even faster, maybe exploiting some strange method in Regexp or some weird construct.

Regexp engines vary in how they implement searches, but, in general, anchor your patterns for speed, and avoid greedy matches, especially when searching long strings.

The best thing to do, until you're familiar with how a particular engine works, is to do benchmarks and add/remove anchors, try limiting searches, use wildcards vs. explicit matches, etc.

The Fruity gem is very useful for quickly benchmarking things, because it's smart. Ruby's built-in Benchmark code is also useful, though you can write tests that fool you by not being careful.

I've used both in many answers here on Stack Overflow, so you can search through my answers and will see lots of little tricks and results to give you ideas of how to write faster code.

The biggest thing to remember is, it's bad to prematurely optimize your code before you know where the slowdowns occur.

Grega's answer is great in explaining why the original code does not work and two ways to fix the issue. However, this solution is not very flexible; consider the case where your closure includes a method call on a non-Serializable class that you have no control over. You can neither add the Serializable tag to this class nor change the underlying implementation to change the method into a function.

Nilesh presents a great workaround for this, but the solution can be made both more concise and general:

def genMapper[A, B](f: A => B): A => B = {
  val locker = com.twitter.chill.MeatLocker(f)
  x => locker.get.apply(x)
}

This function-serializer can then be used to automatically wrap closures and method calls:

rdd map genMapper(someFunc)

This technique also has the benefit of not requiring the additional Shark dependencies in order to access KryoSerializationWrapper, since Twitter's Chill is already pulled in by core Spark

use window.localStorage... like this

var refresh = $window.localStorage.getItem('refresh');
console.log(refresh);
if (refresh===null){
    window.location.reload();
    $window.localStorage.setItem('refresh', "1");
}

It's work for me

Found the solution to this problem:

gradle assemble -info gave me the hint that the Manifests have different SDK Versions and cannot be merged.

I needed to edit my Manifests and build.gradle file and everything worked again.

To be clear you need to edit the uses-sdk in the AndroidManifest.xml

<uses-sdk android:minSdkVersion="14" android:targetSdkVersion="16" />

and the android section, particularly minSdkVersion and targetSdkVersion in the build.gradle file

android {
    compileSdkVersion 17
    buildToolsVersion "17.0.0"

    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 16
    }
}

The original question asked for ignoring SVN and CVS directories, which can be done by adding -prune to the find command. E.g to ignore CVS:

find . -name CVS -prune -o -exec mv '{}' `echo {} | tr '[A-Z]' '[a-z]'` \; -print

[edit] I tried this out, and embedding the lower-case translation inside the find didn't work for reasons I don't actually understand. So, amend this to:

$> cat > tolower
#!/bin/bash
mv $1 `echo $1 | tr '[:upper:]' '[:lower:]'`
^D
$> chmod u+x tolower 
$> find . -name CVS -prune -o -exec tolower '{}'  \;

The trick is to

1. create a CNAME for www.myapp.com to myapp.heroku.com
2. create a 301 redirection from myapp.com to www.myapp.com

As far as I know, you can't do this using current implementations of CSS. To make two column, equal height-ed you need JS.

Although it is not a good solution but may solve your problem. You need to use position absolute in #yellow element!

#yellow {height: 100%; background: yellow; position: absolute; top: 0px; left: 0px;}_x000D_
.container-fluid {position: static !important;}

Use jquery's off and on

As @kojiro said, you don't want to "run" this file. Source it as he says. It should get "sourced" at startup. Sourcing just means running every line in the file, including the one you want to get run. If you want to make sure a folder is in a certain path environment variable (as it seems you want from one of your comments on another solution), execute

$ echo $PATH

At the command line. If you want to check that your ~/.bash_profile is being sourced, either at startup as it should be, or when you source it manually, enter the following line into your ~/.bash_profile file:

$ echo "Hello I'm running stuff in the ~/.bash_profile!"

The simple answer is to turn off async. But that's the wrong thing to do. The correct answer is to re-think how you write the rest of your code.

Instead of writing this:

function functABC(){
    $.ajax({
        url: 'myPage.php',
        data: {id: id},
        success: function(data) {
            return data;
        }
    });
}

function foo () {
    var response = functABC();
    some_result = bar(response);
    // and other stuff and
    return some_result;
}

You should write it like this:

function functABC(callback){
    $.ajax({
        url: 'myPage.php',
        data: {id: id},
        success: callback
    });
}

function foo (callback) {
    functABC(function(data){
        var response = data;
        some_result = bar(response);
        // and other stuff and
        callback(some_result);
    })
}

That is, instead of returning result, pass in code of what needs to be done as callbacks. As I've shown, callbacks can be nested to as many levels as you have function calls.

A quick explanation of why I say it's wrong to turn off async:

Turning off async will freeze the browser while waiting for the ajax call. The user cannot click on anything, cannot scroll and in the worst case, if the user is low on memory, sometimes when the user drags the window off the screen and drags it in again he will see empty spaces because the browser is frozen and cannot redraw. For single threaded browsers like IE7 it's even worse: all websites freeze! Users who experience this may think you site is buggy. If you really don't want to do it asynchronously then just do your processing in the back end and refresh the whole page. It would at least feel not buggy.

Just a pure javascript version (without jquery) of the great amirnissim's solution:

listener = function(event) {
      var suggestion_selected = document.getElementsByClassName('.pac-item-selected').length > 0;
      if (event.which === 13 && !suggestion_selected) {
        var e = JSON.parse(JSON.stringify(event));
        e.which = 40;
        e.keyCode = 40;
        orig_listener.apply(input, [e]);
      }
      orig_listener.apply(input, [event]);
    };

how to completely clear localstorage

localStorage.clear();

how to completely clear sessionstorage

sessionStorage.clear();

[...] Cookies ?

var cookies = document.cookie;

for (var i = 0; i < cookies.split(";").length; ++i)
{
    var myCookie = cookies[i];
    var pos = myCookie.indexOf("=");
    var name = pos > -1 ? myCookie.substr(0, pos) : myCookie;
    document.cookie = name + "=;expires=Thu, 01 Jan 1970 00:00:00 GMT";
}

is there any way to get the value back after clear these ?

No, there isn't. But you shouldn't rely on this if this is related to a security question.

This should work

render(){_x000D_
_x000D_
 var payments = [];_x000D_
_x000D_
 for(let i = 0; i < noGuest; i++){_x000D_
_x000D_
  payments.push(_x000D_
   <View key = {i}>_x000D_
    <View>_x000D_
     <TextInput />_x000D_
    </View>_x000D_
    <View>_x000D_
     <TextInput />_x000D_
    </View>_x000D_
    <View>_x000D_
     <TextInput />_x000D_
    </View>_x000D_
   </View>_x000D_
  )_x000D_
 }_x000D_
 _x000D_
 return (_x000D_
  <View>_x000D_
   <View>_x000D_
    <View><Text>No</Text></View>_x000D_
    <View><Text>Name</Text></View>_x000D_
    <View><Text>Preference</Text></View>_x000D_
   </View>_x000D_
_x000D_
   { payments }_x000D_
  </View>_x000D_
 )_x000D_
}

With async actions (timers, ajax) you can override the property isDefaultPrevented like this:

$('a').click(function(evt){
  e.preventDefault();

  // in async handler (ajax/timer) do these actions:
  setTimeout(function(){
    // override prevented flag to prevent jquery from discarding event
    evt.isDefaultPrevented = function(){ return false; }
    // retrigger with the exactly same event data
    $(this).trigger(evt);
  }, 1000);
}

This is most complete way of retriggering the event with the exactly same data.

testCompile is deprecated. Gradle 7 compatible:

dependencies {
...
   testImplementation 'junit:junit:4.13'
}

and if you use the default folder structure (src/test/java/...) the test section is simply:

test {
    useJUnit()
}

Finally:

gradlew clean test

Alos see: https://docs.gradle.org/current/userguide/java_testing.html

1. Add docker group

$ sudo groupadd docker

2. Add your current user to docker group

$ sudo usermod -aG docker $USER

3. Switch session to docker group

$ newgrp - docker

4. Run an example to test

$ docker run hello-world

It's incorrect, but you can try this instead:

select
    a.x,
    ( select b.y from b where b.v = a.v) as by,
    ( select b.z from b where b.v = a.v) as bz
from a

you can also use subquery in join

 select
        a.x,
        b.y,
        b.z
    from a
    left join (select y,z from b where ... ) b on b.v = a.v

or

   select
        a.x,
        b.y,
        b.z
    from a
    left join b on b.v = a.v

You might want to :

• Check that auto-commit is off
• Open Connection
• Send multiple batches of inserts in a single transaction (size of about 4000-10000 rows ? you see)
• Close connection

Depending on how well your server scales (its definitively ok with PostgreSQl, Oracle and MSSQL), do the thing above with multiple threads and multiple connections.

I'm not aware of anything built-in. It's pretty simple to implement:

class assertMethodIsCalled(object):
    def __init__(self, obj, method):
        self.obj = obj
        self.method = method

    def called(self, *args, **kwargs):
        self.method_called = True
        self.orig_method(*args, **kwargs)

    def __enter__(self):
        self.orig_method = getattr(self.obj, self.method)
        setattr(self.obj, self.method, self.called)
        self.method_called = False

    def __exit__(self, exc_type, exc_value, traceback):
        assert getattr(self.obj, self.method) == self.called,
            "method %s was modified during assertMethodIsCalled" % self.method

        setattr(self.obj, self.method, self.orig_method)

        # If an exception was thrown within the block, we've already failed.
        if traceback is None:
            assert self.method_called,
                "method %s of %s was not called" % (self.method, self.obj)

class test(object):
    def a(self):
        print "test"
    def b(self):
        self.a()

obj = test()
with assertMethodIsCalled(obj, "a"):
    obj.b()

This requires that the object itself won't modify self.b, which is almost always true.

This might be more desirable, that is use float instead

SELECT fullName, CAST(totalBal as float) totalBal FROM client_info ORDER BY totalBal DESC

My issue was that I was on a machine with node version 0.12.2, but that had an old 1.x.x version of npm. Be sure to update your version of npm: sudo npm install -g npm Once that is done, remove any existing node-sass and reinstall it via npm.

There is no answer on how to do this on CentOS. On Centos, you can add following to Dockerfile

RUN echo "user ALL=(root) NOPASSWD:ALL" > /etc/sudoers.d/user && \
    chmod 0440 /etc/sudoers.d/user

You should consider using FireBug for JavaScript debugging. It will let you interactively inspect all of your variables, and even step through functions.

Alright so after some debugging the following dependencies are using an older version of touch:

./node_modules/bower/node_modules/decompress-zip/package.json:    "touch": "0.0.3"
./node_modules/bower/node_modules/lockfile/package.json:    "touch": "0"
./node_modules/gulp-nodemon/node_modules/nodemon/package.json:    "touch": "1.0.0",
./node_modules/gulp-nodemon/node_modules/touch/package.json:    "touch": "./bin/touch.js"
./node_modules/nodemon/package.json:    "touch": "~0.0.3",

With that I was able to get meanJS working with node 5.

Here is the history on the commands I ran:

git clone https://github.com/meanjs/mean.git
cd mean
nvm install 5
nvm use 5
npm install
which node-gyp
npm install -g node-pre-gyp
sudo xcodebuild -license
npm install

Had some issues and then:

I added the following line:

#!/usr/bin/env node

To the top of the file ./mean/node_modules/.bin/touch

And then:

npm install

And of course maybe throw in a sudo rm -rf ./node_modules && npm cache clean before retrying.

None of the solutions listed worked for me. Instead, I ended up uninstalling and reinstalling Homebrew, which did the trick. Uninstall instructions may be found here: http://osxdaily.com/2018/08/12/how-uninstall-homebrew-mac/

Do you have Egit installed yet? If not, go to Window->Preferences->Install/Updates->Available Software Sites. Click on add and paste this link http://download.eclipse.org/egit/updates

For Name, you can just put "EGit". After you have EGit installed, follow this tutorial. It helped me a lot!

This is a feedback to comments in Sid Shah's answer, regarding how to disable animations using:

[UIView setAnimationsEnabled:enabled];

Code:

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:NO];
    [UIView setAnimationsEnabled:NO];

    // Stackoverflow #26357162 to force orientation
    NSNumber *value = [NSNumber numberWithInt:UIInterfaceOrientationLandscapeRight];
    [[UIDevice currentDevice] setValue:value forKey:@"orientation"];
}

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:NO];
    [UIView setAnimationsEnabled:YES];
}

.csv field sizes are controlled via [Python 3.Docs]: csv.field_size_limit([new_limit]) (emphasis is mine):

Returns the current maximum field size allowed by the parser. If new_limit is given, this becomes the new limit.

It is set by default to 131072 or 0x20000 (128k), which should be enough for any decent .csv:

>>> import csv
>>>
>>>
>>> limit0 = csv.field_size_limit()
>>> limit0
131072
>>> "0x{0:016X}".format(limit0)
'0x0000000000020000'

However, when dealing with a .csv file (with the correct quoting and delimiter) having (at least) one field longer than this size, the error pops up.
To get rid of the error, the size limit should be increased (to avoid any worries, the maximum possible value is attempted).

Behind the scenes (check [GitHub]: python/cpython - (master) cpython/Modules/_csv.c for implementation details), the variable that holds this value is a C long ([Wikipedia]: C data types), whose size varies depending on CPU architecture and OS (ILP). The classical difference: for a 64bit OS (and Python build), the long type size (in bits) is:

• Nix: 64
• Win: 32

When attempting to set it, the new value is checked to be in the long boundaries, that's why in some cases another exception pops up (because sys.maxsize is typically 64bit wide - encountered on Win):

>>> import sys, ctypes as ct
>>>
>>>
>>> sys.platform, sys.maxsize, ct.sizeof(ct.c_void_p) * 8, ct.sizeof(ct.c_long) * 8
('win32', 9223372036854775807, 64, 32)
>>>
>>> csv.field_size_limit(sys.maxsize)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
OverflowError: Python int too large to convert to C long

To avoid running into this problem, set the (maximum possible) limit (LONG_MAX), using an artifice (thanks to [Python 3.Docs]: ctypes - A foreign function library for Python). It should work on Python 3 and Python 2, on any CPU / OS.

>>> csv.field_size_limit(int(ct.c_ulong(-1).value // 2))
131072
>>> limit1 = csv.field_size_limit()
>>> limit1
2147483647
>>> "0x{0:016X}".format(limit1)
'0x000000007FFFFFFF'

64bit Python on a Nix like OS:

>>> import sys, csv, ctypes as ct
>>>
>>>
>>> sys.platform, sys.maxsize, ct.sizeof(ct.c_void_p) * 8, ct.sizeof(ct.c_long) * 8
('linux', 9223372036854775807, 64, 64)
>>>
>>> csv.field_size_limit()
131072
>>>
>>> csv.field_size_limit(int(ct.c_ulong(-1).value // 2))
131072
>>> limit1 = csv.field_size_limit()
>>> limit1
9223372036854775807
>>> "0x{0:016X}".format(limit1)
'0x7FFFFFFFFFFFFFFF'

For 32bit Python, things should run smoothly without the artifice (as both sys.maxsize and LONG_MAX are 32bit wide).
If this maximum value is still not enough, then the .csv would need manual intervention in order to be processed from Python.

Check the following resources for more details on:

• Playing with C types boundaries from Python: [SO]: Maximum and minimum value of C types integers from Python (@CristiFati's answer)
• Python 32bit vs 64bit differences: [SO]: How do I determine if my python shell is executing in 32bit or 64bit mode on OS X? (@CristiFati's answer)

Yes, it is possible, and has been implemented by popular usability testing website Silverback. If you look through the source code you can see that the background is made up of several images, placed on top of each other.

Here is the article demonstrating how to do the effect can be found on Vitamin. A similar concept for wrapping these 'onion skin' layers can be found on A List Apart.

I'd recommend application/octet-stream as RFC2046 says "The "octet-stream" subtype is used to indicate that a body contains arbitrary binary data" and "The recommended action for an implementation that receives an "application/octet-stream" entity is to simply offer to put the data in a file[...]".

I think that way you will get better handling from arbitrary programs, that might barf when encountering your unknown mime type.

You could consider using an external tool like ffmpeg to merge the images into a movie (see answer here) or you could try to use OpenCv to combine the images into a movie like the example here.

I'm attaching below a code snipped I used to combine all png files from a folder called "images" into a video.

import cv2
import os

image_folder = 'images'
video_name = 'video.avi'

images = [img for img in os.listdir(image_folder) if img.endswith(".png")]
frame = cv2.imread(os.path.join(image_folder, images[0]))
height, width, layers = frame.shape

video = cv2.VideoWriter(video_name, 0, 1, (width,height))

for image in images:
    video.write(cv2.imread(os.path.join(image_folder, image)))

cv2.destroyAllWindows()
video.release()

Right click on icon --> Properties --> Advanced --> Check checkbox run as Administrator and everytime it will open under Admin Mode (Same for Windows 8)

Here we have a way to fetch previous and next records using single MySQL query. Where 5 is the id of current record.

select * from story where catagory=100 and  (
    id =(select max(id) from story where id < 5 and catagory=100 and order by created_at desc) 
    OR 
    id=(select min(id) from story where id > 5 and catagory=100 order by created_at desc) )

There is a statistics library if you are using python >= 3.4

https://docs.python.org/3/library/statistics.html

You may use it's mean method like this. Let's say you have a list of numbers of which you want to find mean:-

list = [11, 13, 12, 15, 17]
import statistics as s
s.mean(list)

It has other methods too like stdev, variance, mode, harmonic mean, median etc which are too useful.

Following leppie's answer, why not make MetaData an interface:

public interface IMetaData { }

public class Metadata<DataType> : IMetaData where DataType : struct
{
    private DataType mDataType;
}

In your pom.xml you should add distributionManagement configuration to where to deploy.

In the following example I have used file system as the locations.

<distributionManagement>
       <repository>
         <id>internal.repo</id>
         <name>Internal repo</name>
         <url>file:///home/thara/testesb/in</url>
       </repository>
   </distributionManagement>

you can add another location while deployment by using the following command (but to avoid above error you should have at least 1 repository configured) :

mvn deploy -DaltDeploymentRepository=internal.repo::default::file:///home/thara/testesb/in

You actually invoked undefined behaviour.

Returning the address of a temporary works, but as temporaries are destroyed at the end of a function the results of accessing them will be undefined.

So you did not modify a but rather the memory location where a once was. This difference is very similar to the difference between crashing and not crashing.

This is how you do it:

<bean id="systemPrereqs" class="org.springframework.beans.factory.config.MethodInvokingFactoryBean" scope="prototype">
             <property name="targetObject" value="#{@systemProperties}" />
             <property name="targetMethod" value="putAll" />
             <property name="arguments">
                   <util:properties>
                       <prop key="deployment.env">dev</prop>
                   </util:properties>
            </property>
    </bean>

But remember spring gets loaded first and then it will load this bean MethodInvokingFactoryBean. So if you are trying to use this for your test case then make sure that you use depends-on. For e.g. in this case

In case you are using it for your main class better to set this property using your pom.xml as

<systemProperty>
    <name>deployment.env</name>
    <value>dev</value>
</systemProperty>

var elValue     = "-12,erer3  4,-990.234sdsd";

var isNegetive = false;
if(elValue.indexOf("-")==0) isNegetive=true;

elValue     = elValue.replace( /[^\d\.]*/g, '');
elValue     = isNaN(Number(elValue)) ? 0 : Number(elValue);

if(isNegetive) elValue = 0 - elValue;

alert(elValue); //-1234990.234

It might be helpful to rely on the Workbook factory to instantiate the workbook object since the factory method will do the detection of xls or xlsx for you. Reference: http://apache-poi.1045710.n5.nabble.com/How-to-check-for-valid-excel-files-using-POI-without-checking-the-file-extension-td2341055.html

IWorkbook workbook = WorkbookFactory.Create(inputStream);

If you're not sure of the Sheet's name but you are sure of the index (0 based), you can grab the sheet like this:

ISheet sheet = workbook.GetSheetAt(sheetIndex);

You can then iterate through the rows using code supplied by the accepted answer from mj82

const is similar to static we can access both varables with class name but diff is static variables can be modified and const can not.

In my experience, using a PYTHONPATH variable at all is usually the wrong approach, because it does not play nicely with VENV on windows. PYTHON on loading will prepare the path by prepending PYTHONPATH to the path, which can result in your carefully prepared Venv preferentially fetching global site packages.

Instead of using PYTHON path, include a pythonpath.pth file in the relevant site-packages directory (although beware custom pythons occasionally look for them in different locations, e.g. enthought looks in the same directory as python.exe for its .pth files) with each virtual environment. This will act like a PYTHONPATH only it will be specific to the python installation, so you can have a separate one for each python installation/environment. Pycharm integrates strongly with VENV if you just go to yse the VENV's python as your python installation.

See e.g. this SO question for more details on .pth files....

As a workaround, you can create a hidden worksheet, which would hold the changed value. The cell on the visible, protected worksheet should display the value from the hidden worksheet using a simple formula.

You will be able to change the displayed value through the hidden worksheet, while your users won't be able to edit it.

The direct replacement is if/elif/else.

However, in many cases there are better ways to do it in Python. See "Replacements for switch statement in Python?".

It's not good practice. You soon will get confused about it. It looks similiar to a common error: misuse "=" and "==" operators.

You should break it into 2 lines of codes. It not only helps to make the code clearer, but also easy to refactor in the future. Imagine that you change the IF condition? You may accidently remove the line and your variable no longer get the value assigned to it.

If you want to use a character as a small integer, the safest way to do it is with the int8_tand uint8_t types.
