meshgrid helps in creating a rectangular grid from two 1-D arrays of all pairs of points from the two arrays.

x = np.array([0, 1, 2, 3, 4])
y = np.array([0, 1, 2, 3, 4])

Now, if you have defined a function f(x,y) and you wanna apply this function to all the possible combination of points from the arrays 'x' and 'y', then you can do this:

f(*np.meshgrid(x, y))

Say, if your function just produces the product of two elements, then this is how a cartesian product can be achieved, efficiently for large arrays.

It is possible to extend the relation with query functions:

<?php
public function comments()
{
    return $this->hasMany('Comment')->orderBy('column');
}

[edit after comment]

<?php
class User
{
    public function comments()
    {
        return $this->hasMany('Comment');
    }
}

class Controller
{
    public function index()
    {
        $column = Input::get('orderBy', 'defaultColumn');
        $comments = User::find(1)->comments()->orderBy($column)->get();

        // use $comments in the template
    }
}

default User model + simple Controller example; when getting the list of comments, just apply the orderBy() based on Input::get(). (be sure to do some input-checking ;) )

If you're doing it via CMD as you say, then you can just enter the command like so:

path\to\your.exe 

which will open it within the same window. For example in C++:

system("path\\to\\your.exe"); // Double backslash for escaping

will open your.exe in the current CMD window. Likewise to start with a new window, just go for:

system("start path\\to\\your.exe");

If you go for the first option, you would have to clear your screen unless you wanted to have the command to open your.exe on the screen still.

I had to create a timer for teachers grading students' work. Here's one I used which is entirely based on elapsed time since the grading begun by storing the system time at the point that the page is loaded, and then comparing it every half second to the system time at that point:

var startTime = Math.floor(Date.now() / 1000); //Get the starting time (right now) in seconds
localStorage.setItem("startTime", startTime); // Store it if I want to restart the timer on the next page

function startTimeCounter() {
    var now = Math.floor(Date.now() / 1000); // get the time now
    var diff = now - startTime; // diff in seconds between now and start
    var m = Math.floor(diff / 60); // get minutes value (quotient of diff)
    var s = Math.floor(diff % 60); // get seconds value (remainder of diff)
    m = checkTime(m); // add a leading zero if it's single digit
    s = checkTime(s); // add a leading zero if it's single digit
    document.getElementById("idName").innerHTML = m + ":" + s; // update the element where the timer will appear
    var t = setTimeout(startTimeCounter, 500); // set a timeout to update the timer
}

function checkTime(i) {
    if (i < 10) {i = "0" + i};  // add zero in front of numbers < 10
    return i;
}

startTimeCounter();

This way, it really doesn't matter if the 'setTimeout' is subject to execution delays, the elapsed time is always relative the system time when it first began, and the system time at the time of update.

I came upon a similar issue recently and following Fabian's advice actually led me to the solution. Turns out with client certs you have to ensure two things:

1. The private key is actually being exported as part of the cert.

2. The application pool identity running the app has access to said private key.

In our case I had to:

1. Import the pfx file into the local server store while checking the export checkbox to ensure the private key was sent out.
2. Using MMC console, grant the service account used access to the private key for the cert.

The trusted root issue explained in other answers is a valid one, it was just not the issue in our case.

The error message is actually correct if not obvious. It says that your DOCTYPE must have a SYSTEM identifier. I assume yours only has a public identifier.

You'll get the error with (for instance):

<!DOCTYPE persistence PUBLIC
    "http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">

You won't with:

<!DOCTYPE persistence PUBLIC
    "http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd" "">

Notice "" at the end in the second one -- that's the system identifier. The error message is confusing: it should say that you need a system identifier, not that you need a space between the publicId and the (non-existent) systemId.

By the way, an empty system identifier might not be ideal, but it might be enough to get you moving.

To add on to the other answers here, if you would like to create a new object of a third different type with a where clause (e.g. one that is not your Entity Framework object) you can do this:

public IEnumerable<ThirdNonEntityClass> demoMethod(IEnumerable<int> property1Values)
{
    using(var entityFrameworkObjectContext = new EntityFrameworkObjectContext )
    {
        var result = entityFrameworkObjectContext.SomeClass
            .Join(entityFrameworkObjectContext.SomeOtherClass,
                sc => sc.property1,
                soc => soc.property2,
                (sc, soc) => new {sc, soc})
            .Where(s => propertyValues.Any(pvals => pvals == es.sc.property1)
            .Select(s => new ThirdNonEntityClass 
            {
                dataValue1 = s.sc.dataValueA,
                dataValue2 = s.soc.dataValueB
            })
            .ToList();
    }

    return result;

}    

Pay special attention to the intermediate object that is created in the Where and Select clauses.

Note that here we also look for any joined objects that have a property1 that matches one of the ones in the input list.

I know this is a bit more complex than what the original asker was looking for, but hopefully it will help someone.

Fixed positioning will do what you need:

#main
{         
    position:fixed;
    top:0px;
    bottom:0px;
    left:0px;
    right:0px;
}

An easy way that is compatible pretty much everywhere is to set font-size: 0 on the container, provided you don't have any descendent text nodes you need to style (though it is trivial to override this where needed).

.nospace {
   font-size: 0;
}

jsFiddle.

You could also change from the default display: inline into block or inline-block. Be sure to use the workarounds required for <= IE7 (and possibly ancient Firefoxes) for inline-block to work.

Using both method you find easy if you wont last seven days you use (currentdaynumber+7-1)%7,(currentdaynumber+7-2)%7.....upto 6

public static String getDayName(int day){
    switch(day){
        case 0:
            return "Sunday";
        case 1:
            return "Monday";
        case 2:
            return "Tuesday";
        case 3:
            return "Wednesday";
        case 4:
            return "Thursday";
        case 5:
            return  "Friday";
        case 6:
            return "Saturday";
    }

    return "Worng Day";
}
public static String getCurrentDay(){
    SimpleDateFormat dayFormat = new SimpleDateFormat("EEEE", Locale.US);
    Calendar calendar = Calendar.getInstance();
    return dayFormat.format(calendar.getTime());

}

Take a look at the System log in Windows EventViewer (eventvwr from the command line).

Just adding .First to your bananaToken should do it:
foodJsonObj["food"]["fruit"]["orange"].Parent.AddAfterSelf(bananaToken .First);
.First basically moves past the { to make it a JProperty instead of a JToken.

@Brian Rogers, Thanks I forgot the .Parent. Edited

I would think Eigenface, which you are doing already, is the way to go if you want to calculate the distance between faces. You could try out different approaches like Support Vector Machine or Hidden Markov Model. I found a page that lists major algorithms that could be used for facial recognition: Face Recognition Homepage.

Also, when you say "better performance," do you mean speed or accuracy? What kind of problem are you having? How varying are the data? Are they mostly frontal face or do they include profiles?

I use sandbox="..."

• allow-forms allows form submission
• allow-popups allows popups
• allow-pointer-lock allows pointer lock
• allow-same-origin allows the document to maintain its origin
• allow-scripts allows JavaScript execution, and also allows features to trigger automatically
• allow-top-navigation allows the document to break out of the frame by navigating the top-level window

Top navigation is what you want to prevent, so leave that out and it will not be allowed. Anything left out will be blocked

ex.

        <iframe sandbox="allow-same-origin allow-scripts allow-popups allow-forms" src="http://www.example.com"</iframe>

If it were not for the dashes and underscores, the easiest solution would be

my_little_string.isalnum()

(Section 3.6.1 of the Python Library Reference)

None of those are precisely the same, though they will all have the same net effect.

The difference between the first and the second is that if you happen to be on the main application thread when executing the code, the first one (runOnUiThread()) will execute the Runnable immediately. The second one (post()) always puts the Runnable at the end of the event queue, even if you are already on the main application thread.

The third one, assuming you create and execute an instance of BackgroundTask, will waste a lot of time grabbing a thread out of the thread pool, to execute a default no-op doInBackground(), before eventually doing what amounts to a post(). This is by far the least efficient of the three. Use AsyncTask if you actually have work to do in a background thread, not just for the use of onPostExecute().

the way i found was to find the project compiler output (project structure > project). then find the complied folder of the module you wish to turn to a jar, compress it with zip and change the extension of the output from zip to jar.

To understand get and set, it's all related to how variables are passed between different classes.

The get method is used to obtain or retrieve a particular variable value from a class.

A set value is used to store the variables.

The whole point of the get and set is to retrieve and store the data values accordingly.

What I did in this old project was I had a User class with my get and set methods that I used in my Server class.

The User class's get set methods:

public int getuserID()
    {
        //getting the userID variable instance
        return userID;
    }
    public String getfirstName()
    {
        //getting the firstName variable instance
        return firstName;
    }
    public String getlastName()
    {
        //getting the lastName variable instance
        return lastName;
    }
    public int getage()
    {
        //getting the age variable instance
        return age;
    }

    public void setuserID(int userID)
    {
        //setting the userID variable value
        this.userID = userID;
    }
    public void setfirstName(String firstName)
    {
        //setting the firstName variable text
        this.firstName = firstName;
    }
    public void setlastName(String lastName)
    {
        //setting the lastName variable text
        this.lastName = lastName;
    }
    public void setage(int age)
    {
        //setting the age variable value
        this.age = age;
    }
}

Then this was implemented in the run() method in my Server class as follows:

//creates user object
                User use = new User(userID, firstName, lastName, age);
                //Mutator methods to set user objects
                use.setuserID(userID);
                use.setlastName(lastName);
                use.setfirstName(firstName);               
                use.setage(age); 

There's no need to check for EOF in python, simply do:

with open('t.ini') as f:
   for line in f:
       # For Python3, use print(line)
       print line
       if 'str' in line:
          break

Why the with statement:

It is good practice to use the with keyword when dealing with file objects. This has the advantage that the file is properly closed after its suite finishes, even if an exception is raised on the way.

It surprises me that no one mentioned the key difference between these two is that the temp table supports parallel insert while the table variable doesn't. You should be able to see the difference from the execution plan. And here is the video from SQL Workshops on Channel 9.

This also explains why you should use a table variable for smaller tables, otherwise use a temp table, as SQLMenace answered before.

I simply use

git fetch origin

to fetch the remote changes, and then I view both local and pending remote commits (and their associated changes) with the nice gitk tool involving the --all argument like:

gitk --all

I got this error when my server ran out of disk space and closed the connection midway during generating the response and simply closed the connection

I would like also to suggest following project: https://github.com/NightWhistler/HtmlSpanner

Usage is almost the same as default android converter:

(new HtmlSpanner()).fromHtml()

Found it after I already started by own implementation of html to spannable converter, because standard Html.fromHtml does not provide enough flexibility over rendering control and even no possibility to use custom fonts from ttf

This is one of the features missing from standard Scala that I have found so useful that I add it to my personal library. (You probably should have a personal library, too.) The code goes like so:

def printToFile(f: java.io.File)(op: java.io.PrintWriter => Unit) {
  val p = new java.io.PrintWriter(f)
  try { op(p) } finally { p.close() }
}

and it's used like this:

import java.io._
val data = Array("Five","strings","in","a","file!")
printToFile(new File("example.txt")) { p =>
  data.foreach(p.println)
}

Let us assume the database character set is UTF-8, which is the recommended setting in recent versions of Oracle. In this case, some characters take more than 1 byte to store in the database.

If you define the field as VARCHAR2(11 BYTE), Oracle can use up to 11 bytes for storage, but you may not actually be able to store 11 characters in the field, because some of them take more than one byte to store, e.g. non-English characters.

By defining the field as VARCHAR2(11 CHAR) you tell Oracle it can use enough space to store 11 characters, no matter how many bytes it takes to store each one. A single character may require up to 4 bytes.

all please check the updated code as we have to use

 form-control-static not only form-control

Instead of fixing your "master" branch, it's way easier to swap it with your "desired-master" by renaming the branches. See https://stackoverflow.com/a/2862606/2321594. This way you wouldn't even leave any trace of multiple revert logs.

and always remember this venerable explanation of Spaces + Tabs:

http://www.jwz.org/doc/tabs-vs-spaces.html

The function STR_TO_DATE(COLUMN, '%input_format') can do it, you only have to specify the input format. Example : to convert p052011

SELECT STR_TO_DATE('p052011','p%m%Y') FROM your_table;

The result : 2011-05-00

To find last data row, in case you created table template in excel where it is filled partially or in between rows are empty. Logic:

int count = 0;
int emptyrow=0;
int irow=0;
while (rowIterator.hasNext()) {
    row = (Row) rowIterator.next();
    if (count != 0 && !checkIfRowIsEmpty(row)) { }
    else{
        if(count!=0 && emptyrow==irow){
            emptyrow++;
        }else{
            emptyrow=0;
            irow=0;
        }
    }
    if(emptyrow>0){
        irow++;
    }
    if(emptyrow>3){
        break;
    }
    count++;
}

You can use HTML5 pattern attribute to do this:

<form>
    <input type='text' pattern='[A-Za-z\\s]*'/>
</form>

If the user enters an input that conflicts with the pattern, it will show an error dialogue automatically.

>>> now
datetime.datetime(2016, 1, 28, 18, 26, 12, 980861)
>>> later = now.replace(month=now.month+1)
>>> later
datetime.datetime(2016, 2, 28, 18, 26, 12, 980861)

EDIT: Fails on

y = datetime.date(2016, 1, 31); y.replace(month=2) results in ValueError: day is out of range for month

Ther is no simple way to do it, but you can use your own function like answered below.

This is worked for me, anyone can try it

$("#myModal").on("hidden.bs.modal", function () {
    for (instance in CKEDITOR.instances)
        CKEDITOR.instances[instance].destroy();
    $('#myModal .modal-body').html('');    
});

you can open ckEditor in Modal window

I suggest using Render, as the ElementRef API doc suggests:

... take a look at Renderer which provides API that can safely be used even when direct access to native elements is not supported. Relying on direct DOM access creates tight coupling between your application and rendering layers which will make it impossible to separate the two and deploy your application into a web worker or Universal.

Always use the Renderer for it will make you code (or library you right) be able to work when using Universal or WebWorkers.

import { Directive, ElementRef, HostListener, Input, Renderer } from '@angular/core';

export class HighlightDirective {
    constructor(el: ElementRef, renderer: Renderer) {
        renderer.setElementProperty(el.nativeElement, 'innerHTML', 'some new value');
    }
}

It doesn't look like Render has a getElementProperty() method though, so I guess we still need to use NativeElement for that part. Or (better) pass the content in as an input property to the directive.

You can actually pass as many values as you want to any javascript function. The explicitly named parameters will get the first few values, but ALL parameters will be stored in the arguments array.

To pass the arguments array in "unpacked" form, you can use apply, like so (c.f. Functional Javascript):

var otherFunc = function() {
   alert(arguments.length); // Outputs: 10
}

var myFunc = function() {
  alert(arguments.length); // Outputs: 10
  otherFunc.apply(this, arguments);
}
myFunc(1,2,3,4,5,6,7,8,9,10);

div img{ 
    bottom: 0;
    left: 0;
    margin: auto;
    position: absolute;
    right: 0;
    top: 0;
    height:50px;
    width:50px;
}

You can use "find" for remove all files in the /objects directory with 0 in size with the command:

find .git/objects/ -size 0 -delete

Backup is recommended.

I benched a few different ways:

1) microtime + sscanf + date:

sscanf(microtime(), '0.%6s00 %s', $usec, $sec);
$date = date('Y-m-d H:i:s.', $sec) . $usec;

I'm not sure why microtime() returns 10 chars (0.dddddd00) for the microseconds part but maybe someone can tell me ?

$start_ts = microtime(true); for($i = 0; $i < 10000000; $i++) { sscanf(microtime(), '0.%6s00 %s', $usec, $sec); $date = date('Y-m-d H:i:s.', $sec) . $usec; } var_dump((microtime(true) - $start_ts)*1000 . ' ms');
string(18) "22372.335910797 ms" // macOS PHP 5.6.30
string(18) "16772.964000702 ms" // Linux PHP 5.4.16
string(18) "10382.229089737 ms" // Linux PHP 7.3.11 (same linux box as above)

2) DateTime::createFromFormat + Datetime->format:

$now = new DateTime('NOW');
$date = $now->format('Y-m-d H:i:s.u');

not working in PHP 5.x ...

$start_ts = microtime(true); for($i = 0; $i < 10000000; $i++) { $now = new DateTime('NOW'); $date = $now->format('Y-m-d H:i:s.u'); } var_dump((microtime(true) - $start_ts)*1000 . ' ms');

3) gettimeofday + date:

$time = gettimeofday();
$date = date('Y-m-d H:i:s.', $time['sec']) . $time['usec'];

-

$start_ts = microtime(true); for($i = 0; $i < 10000000; $i++) { $time = gettimeofday(); $date = date('Y-m-d H:i:s.', $time['sec']) . $time['usec']; } var_dump((microtime(true) - $start_ts)*1000 . ' ms');

string(18) "14984.534025192 ms" // Linux PHP 5.4.16
string(18) "7799.1390228271 ms" // Linux PHP 7.3.11 (same linux box as above)

4) microtime + number_format + DateTime::createFromFormat + DateTime->format:

$now = DateTime::createFromFormat('U.u', number_format(microtime(true), 6, '.', ''));
$date = $now->format('Y-m-d H:i:s.u');

-

$start_ts = microtime(true); for($i = 0; $i < 10000000; $i++) { $now = DateTime::createFromFormat('U.u', number_format(microtime(true), 6, '.', '')); $date = $now->format('Y-m-d H:i:s.u'); } var_dump((microtime(true) - $start_ts)*1000 . ' ms');
string(18) "83326.496124268 ms" // macOS PHP 5.6.30

string(16) "19107.1870327 ms" // Linux PHP 7.3.11 (same linux box as above)

5) microtime + sprintf + DateTime::createFromFormat + DateTime->format:

$now = DateTime::createFromFormat('U.u', sprintf('%.6f', microtime(true)));
$date = $now->format('Y-m-d H:i:s.u');

-

$start_ts = microtime(true); for($i = 0; $i < 10000000; $i++) { $now = DateTime::createFromFormat('U.u', sprintf('%.6f', microtime(true))); $date = $now->format('Y-m-d H:i:s.u'); } var_dump((microtime(true) - $start_ts)*1000 . ' ms');

I encountered the same error message after unpacking MinGW archives to C:\MinGW and setting the path to environment variable as C:\MinGW\bin;.

When I try to compile I get this error!

gcc: error: CreateProcess: No such file or directory

I finally figured out that some of the downloaded archives were reported broken while unpaking them to C:\MinGW (yet I ignored this initially). Once I deleted the broken files and re-downloaded the whole archives again from SourceForge, unpacked them to C:\MinGW successfully the error was gone, and the compiler worked fine and output my desired hello.exe.

I ran this:

gcc hello.c -o hello

The result result was this (a blinking underscore):

They can be considered as equivalent. The limits in size are the same:

• Maximum length of CLOB (in bytes or OCTETS)) 2 147 483 647
• Maximum length of BLOB (in bytes) 2 147 483 647

There is also the DBCLOBs, for double byte characters.

Be very careful with the Excel MOD(a,b) function and the VBA a Mod b operator. Excel returns a floating point result and VBA an integer.

In Excel =Mod(90.123,90) returns 0.123000000000005 instead of 0.123 In VBA 90.123 Mod 90 returns 0

They are certainly not equivalent!

Equivalent are: In Excel: =Round(Mod(90.123,90),3) returning 0.123 and In VBA: ((90.123 * 1000) Mod 90000)/1000 returning also 0.123

If you intend to share workspace extensions configuration across a team, you should look into the Recommended Extensions feature of Visual Studio Code.

To generate this file, open the command pallet > Configure Recommended Extensions (Workspace Folder). From there, if you wanted to get all of your current extensions and put them in here, you could use the --list-extensions stuff mentioned in other answers, but add some AWK script to make it paste-able into a JSON array (you can get more or less advanced with this as you please - this is just a quick example):

code --list-extensions | awk '{ print "\""$0"\"\,"}'

The advantage of this method is that your team-wide workspace configuration can be checked into source control. With this file present in a project, when the project is opened Visual Studio Code will notify the user that there are recommended extensions to install (if they don't already have them) and can install them all with a single button press.

If you use php5.6 then execute this:

sudo apt-get install php5.6-zip

On a Mac with a US keyboard, you want cmd+/.

Try to use jQuery instead of $ sign when calling the function, it worked in my case as you can see below.

jQuery.noConflict(); 
jQuery('#myModal').modal('show'); 

jQuery.noConflict(); because when jQuery('#myModal').modal('show'); doesn't work, it's caused by having included jQuery twice. Including jQuery 2 times makes modals not to work. and it would resolve the problem in that case, as in my case it is repeating.

As of June 2016, click the settings cog in the top right corner and click edit project at the bottom of the list. Then, scroll to the bottom of the page to the Remove project section.

You can use the .Clear method:

Sheets("Zeros").UsedRange.Clear

Using this you can remove the contents and the formatting of a cell or range without affecting the rest of the worksheet.

I noticed that //noinspection can be auto-generated in IntelliJ

• make sure you have not already a plan @SuppressWarninigs before the statement
• Now you can auto-generate the specific //noinspection by hitting Alt+Enter when you have the warning selected and then use the right arrow key to see the Suppress for ... option

Ended up here when I wanted to suppress a "switch has too few case labels" warning from IntelliJ. I did not find a complete List for IntelliJ's @SuppressWarning support but //noinspection did the trick for me.

You can write your loop like this:

var s = "ABCDEFG";
foreach (var item in s.GetEnumeratorWithIndex())
{
    System.Console.WriteLine("Character: {0}, Position: {1}", item.Value, item.Index);
}

After adding the following struct and extension method.

The struct and extension method encapsulate Enumerable.Select functionality.

public struct ValueWithIndex<T>
{
    public readonly T Value;
    public readonly int Index;

    public ValueWithIndex(T value, int index)
    {
        this.Value = value;
        this.Index = index;
    }

    public static ValueWithIndex<T> Create(T value, int index)
    {
        return new ValueWithIndex<T>(value, index);
    }
}

public static class ExtensionMethods
{
    public static IEnumerable<ValueWithIndex<T>> GetEnumeratorWithIndex<T>(this IEnumerable<T> enumerable)
    {
        return enumerable.Select(ValueWithIndex<T>.Create);
    }
}

From what I saw in Express 4.0 this works for me. This is example of authentication required middleware.

function apiDemandLoggedIn(req, res, next) {

    // if user is authenticated in the session, carry on
    console.log('isAuth', req.isAuthenticated(), req.user);
    if (req.isAuthenticated())
        return next();

    // If not return 401 response which means unauthroized.
    var err = new Error();
    err.status = 401;
    next(err);
}

The pipe, |, is a special-character in regex (meaning "or") and you'll have to escape it with a \.

Using your current regex:

\|.*$

I've tried this in Notepad++, as you've mentioned, and it appears to work well.

I'm going to leave this one here: https://stackoverflow.com/a/14509697/1356953

Please note that this works with java.lang.SuppressWarningsso no need to use a separate annotation.

@SuppressWarnings on a field only suppresses findbugs warnings reported for that field declaration, not every warning associated with that field.

For example, this suppresses the "Field only ever set to null" warning:

@SuppressWarnings("UWF_NULL_FIELD") String s = null; I think the best you can do is isolate the code with the warning into the smallest method you can, then suppress the warning on the whole method.

For the button you can do

<form method="get" action="file.doc">
   <button type="submit">Download!</button>
</form>

What does the exclamation mark after the gem name in the 'DEPENDECIES' group mean?

The exclamation mark appears when the gem was installed using a source other than "https://rubygems.org".

The answer by Hadley gives an interesting reference to Stephen Few's report Dual-Scaled Axes in Graphs Are They Ever the Best Solution?.

I do not know what the OP means with "counts" and "rate" but a quick search gives me Counts and Rates, so I get some data about Accidents in North American Mountaineering¹:

Years<-c("1998","1999","2000","2001","2002","2003","2004")
Persons.Involved<-c(281,248,301,276,295,231,311)
Fatalities<-c(20,17,24,16,34,18,35)
rate=100*Fatalities/Persons.Involved
df<-data.frame(Years=Years,Persons.Involved=Persons.Involved,Fatalities=Fatalities,rate=rate)
print(df,row.names = FALSE)

 Years Persons.Involved Fatalities      rate
  1998              281         20  7.117438
  1999              248         17  6.854839
  2000              301         24  7.973422
  2001              276         16  5.797101
  2002              295         34 11.525424
  2003              231         18  7.792208
  2004              311         35 11.254019

And then I tried to do the graph as Few suggested at page 7 of the aforementioned report (and following the request of OP to graph the counts as a bar chart and the rates as a line chart) :

The other less obvious solution, which works only for time series, is to convert all sets of values to a common quantitative scale by displaying percentage differences between each value and a reference (or index) value. For instance, select a particular point in time, such as the first interval that appears in the graph, and express each subsequent value as the percentage difference between it and the initial value. This is done by dividing the value at each point in time by the value for the initial point in time and then multiplying it by 100 to convert the rate to a percentage, as illustrated below.

df2<-df
df2$Persons.Involved <- 100*df$Persons.Involved/df$Persons.Involved[1]
df2$rate <- 100*df$rate/df$rate[1]
plot(ggplot(df2)+
  geom_bar(aes(x=Years,weight=Persons.Involved))+
  geom_line(aes(x=Years,y=rate,group=1))+
  theme(text = element_text(size=30))
  )

And this is the result:

But I do not like it a lot and I am not able to easily put a legend on it...

I think I am late in answering this question, but it keep coming up in my feed.

Navneet has provided excellent answer. Adding to it visually.

Partitioning helps in elimination of data, if used in WHERE clause, where as bucketing helps in organizing data in each partition into multiple files, so as same set of data is always written in same bucket. Helps a lot in joining of columns.

Suppose, you have a table with five columns, name, server_date, some_col3, some_col4 and some_col5. Suppose, you have partitioned the table on server_date and bucketed on name column in 10 buckets, your file structure will look something like below.

1. server_date=xyz
   • 00000_0
   • 00001_0
   • 00002_0
   • ........
   • 00010_0

Here server_date=xyz is the partition and 000 files are the buckets in each partition. Buckets are calculated based on some hash functions, so rows with name=Sandy will always go in same bucket.

If there are no future dates ...

SELECT * 
FROM   table_name 
WHERE  date_created > (NOW() - INTERVAL 1 MONTH);

Tested.

To help another people with my same problem, the complete answer to Use Toast inside Fragment is:

Activity activity = getActivity();

@Override
public void onClick(View arg0) {

    Toast.makeText(activity,"Text!",Toast.LENGTH_SHORT).show();
}

The name accepted into TR1 (and the draft for the next standard) is std::unordered_map, so if you have that available, it's probably the one you want to use.

Other than that, using it is a lot like using std::map, with the proviso that when/if you traverse the items in an std::map, they come out in the order specified by operator<, but for an unordered_map, the order is generally meaningless.

You can use PSCP to copy files from Windows to Linux.

1. Download PSCP from putty.org
2. Open cmd in the directory with pscp.exe file

3. Type command pscp source_file user@host:destination_file

   • Ex.
     pscp sample.txt [email protected]:/mydata/sample.txt

This is what finally worked for me. Its pretty lame that I had to do all this, but this was the only thing I could find that worked.

After ensuring the library was listed under linked framework and libraries. If its not there you can click the + and hopefully see your framework/pod listed.

Click on your project in the scheme icon (see image below)

Then you should see your framework of focus listed:

Click Manage Schemes.

Then you should see something like this:

Tick the box for your framework, click AutoCreate Schemes now, then close.

Then try to import your framework/pod again.

It worked for me.

Every object of the Class BigDecimal has a method compareTo you can use to compare it to another BigDecimal. The result of compareTo is then compared > 0, == 0 or < 0 depending on what you need. Read the documentation and you will find out.

The operators ==, <, > and so on can only be used on primitive data types like int, long, double or their wrapper classes like Integerand Double.

From the documentation of compareTo:

Compares this BigDecimal with the specified BigDecimal.

Two BigDecimal objects that are equal in value but have a different scale (like 2.0 and 2.00) are considered equal by this method. This method is provided in preference to individual methods for each of the six boolean comparison operators (<, ==, >, >=, !=, <=). The suggested idiom for performing these comparisons is: (x.compareTo(y) <op> 0), where <op> is one of the six comparison operators.

Returns: -1, 0, or 1 as this BigDecimal is numerically less than, equal to, or greater than val.

enumerate is what you want:

for i, s in enumerate(S):
    print s, i

UPDATE:

onActivityCreated() is deprecated from API Level 28.

onCreate():

The onCreate() method in a Fragment is called after the Activity's onAttachFragment() but before that Fragment's onCreateView().
In this method, you can assign variables, get Intent extras, and anything else that doesn't involve the View hierarchy (i.e. non-graphical initialisations). This is because this method can be called when the Activity's onCreate() is not finished, and so trying to access the View hierarchy here may result in a crash.

onCreateView():

After the onCreate() is called (in the Fragment), the Fragment's onCreateView() is called. You can assign your View variables and do any graphical initialisations. You are expected to return a View from this method, and this is the main UI view, but if your Fragment does not use any layouts or graphics, you can return null (happens by default if you don't override).

onActivityCreated():

As the name states, this is called after the Activity's onCreate() has completed. It is called after onCreateView(), and is mainly used for final initialisations (for example, modifying UI elements). This is deprecated from API level 28.

To sum up...
... they are all called in the Fragment but are called at different times.
The onCreate() is called first, for doing any non-graphical initialisations. Next, you can assign and declare any View variables you want to use in onCreateView(). Afterwards, use onActivityCreated() to do any final initialisations you want to do once everything has completed.

If you want to view the official Android documentation, it can be found here:

• onCreate()
• onCreateView()
• onActivityCreated()_

• onCreate() vs onCreateView()
• onCreateView() vs onActivityCreated()

Not always there's a servlet before of an upload (I could use a filter for example). Or could be that the same controller ( again a filter or also a servelt ) can serve many actions, so I think that rely on that servlet configuration to use the getPart method (only for Servlet API >= 3.0), I don't know, I don't like.

In general, I prefer independent solutions, able to live alone, and in this case http://commons.apache.org/proper/commons-fileupload/ is one of that.

List<FileItem> multiparts = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(request);
    for (FileItem item : multiparts) {
        if (!item.isFormField()) {
            //your operations on file
        } else {
            String name = item.getFieldName();
            String value = item.getString();
            //you operations on paramters
        }
}

import sys
import time

a = 0  
for x in range (0,3):  
    a = a + 1  
    b = ("Loading" + "." * a)
    # \r prints a carriage return first, so `b` is printed on top of the previous line.
    sys.stdout.write('\r'+b)
    time.sleep(0.5)
print (a)

Note that you might have to run sys.stdout.flush() right after sys.stdout.write('\r'+b) depending on which console you are doing the printing to have the results printed when requested without any buffering.

In your input tag, place the following:

FYI I did a little research as well and if the name of the font-family you want to apply contains spaces (as an example I take Gill Alt One MT Light), you should write it this way :

strbody= "<BODY style=" & Chr(34) & "font-family:Gill Alt One MT Light" & Chr(34) & ">" & YOUR_TEXT & "</BODY>"

A lot have been analyzed and discussed about a website being detected being driven by Selenium controlled ChromeDriver. Here are my two cents:

According to the article Browser detection using the user agent serving different webpages or services to different browsers is usually not among the best of ideas. The web is meant to be accessible to everyone, regardless of which browser or device an user is using. There are best practices outlined to develop a website to progressively enhance itself based on the feature availability rather than by targeting specific browsers.

However, browsers and standards are not perfect, and there are still some edge cases where some websites still detects the browser and if the browser is driven by Selenium controled WebDriver. Browsers can be detected through different ways and some commonly used mechanisms are as follows:

• Implementing captcha / recaptcha to detect the automatic bots.

You can find a relevant detailed discussion in How does recaptcha 3 know I'm using selenium/chromedriver?

• Detecting the term HeadlessChrome within headless Chrome UserAgent

You can find a relevant detailed discussion in Access Denied page with headless Chrome on Linux while headed Chrome works on windows using Selenium through Python

• Using Bot Management service from Distil Networks

• Using Bot Protection service from Datadome

You can find a relevant detailed discussion in Website using DataDome gets captcha blocked while scraping using Selenium and Python

However, using the user-agent to detect the browser looks simple but doing it well is in fact a bit tougher.

Note: At this point it's worth to mention that: it's very rarely a good idea to use user agent sniffing. There are always better and more broadly compatible way to address a certain issue.

Considerations for browser detection

The idea behind detecting the browser can be either of the following:

• Trying to work around a specific bug in some specific variant or specific version of a webbrowser.
• Trying to check for the existence of a specific feature that some browsers don't yet support.
• Trying to provide different HTML depending on which browser is being used.

Alternative of browser detection through UserAgents

Some of the alternatives of browser detection are as follows:

• Implementing a test to detect how the browser implements the API of a feature and determine how to use it from that. An example was Chrome unflagged experimental lookbehind support in regular expressions.
• Adapting the design technique of Progressive enhancement which would involve developing a website in layers, using a bottom-up approach, starting with a simpler layer and improving the capabilities of the site in successive layers, each using more features.
• Adapting the top-down approach of Graceful degradation in which we build the best possible site using all the features we want and then tweak it to make it work on older browsers.

Solution

To prevent the Selenium driven WebDriver from getting detected, a niche approach would include either/all of the below mentioned approaches:

• Rotating the UserAgent in every execution of your Test Suite using fake_useragent module as follows:

  from selenium import webdriver
  from selenium.webdriver.chrome.options import Options
  from fake_useragent import UserAgent
  
  options = Options()
  ua = UserAgent()
  userAgent = ua.random
  print(userAgent)
  options.add_argument(f'user-agent={userAgent}')
  driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\WebDrivers\ChromeDriver\chromedriver_win32\chromedriver.exe')
  driver.get("https://www.google.co.in")
  driver.quit()
  

You can find a relevant detailed discussion in Way to change Google Chrome user agent in Selenium?

• Rotating the UserAgent in each of your Tests using Network.setUserAgentOverride through execute_cdp_cmd() as follows:

  from selenium import webdriver
  
  driver = webdriver.Chrome(executable_path=r'C:\WebDrivers\chromedriver.exe')
  print(driver.execute_script("return navigator.userAgent;"))
  # Setting user agent as Chrome/83.0.4103.97
  driver.execute_cdp_cmd('Network.setUserAgentOverride', {"userAgent": 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36'})
  print(driver.execute_script("return navigator.userAgent;"))
  

You can find a relevant detailed discussion in How to change the User Agent using Selenium and Python

• Changing the property value of navigator for webdriver to undefined as follows:

  driver.execute_cdp_cmd("Page.addScriptToEvaluateOnNewDocument", {
    "source": """
      Object.defineProperty(navigator, 'webdriver', {
        get: () => undefined
      })
    """
  })

Dealing with reCAPTCHA

While dealing with 2captcha and recaptcha-v3 rather clicking on checkbox associated to the text I'm not a robot, it may be easier to get authenticated extracting and using the data-sitekey.

You can find a relevant detailed discussion in How to identify the 32 bit data-sitekey of ReCaptcha V2 to obtain a valid response programmatically using Selenium and Python Requests?

You must check the certificate hash code.

ServicePointManager.ServerCertificateValidationCallback = (sender, certificate, chain,
    errors) =>
        {
            var hashString = certificate.GetCertHashString();
            if (hashString != null)
            {
                var certHashString = hashString.ToLower();
                return certHashString == "dec2b525ddeemma8ccfaa8df174455d6e38248c5";
            }
            return false;
        };

HTML and XML entities are just a way of referencing a Unicode code-point in a way that reliably works regardless of the encoding of the actual page, making them useful for using esoteric Unicode characters in a page using 7-bit ASCII or some other encoding scheme, ideally on a one-off basis. They're also used to escape the <, >, " and & characters as these are reserved in SGML.

Anyway, Unicode has a number of tick/check characters, as per Wikipedia ( http://en.wikipedia.org/wiki/Tick_(check_mark) ).

Ideally you should save/store your HTML in a Unicode format like UTF-8 or 16, thus obviating the need to use HTML entities to represent a Unicode character. Nonetheless use: ✔ ✔.

✔

✔

Is using hex notation and is the same as

$#10004;

(as 2714 in base 16 is the same as 10004 in base 10)

You can also use CURRENT_TIMESTAMP for this.

According to BOL CURRENT_TIMESTAMP is the ANSI SQL euivalent to GETDATE()

DECLARE @LastChangeDate AS DATE;
SET @LastChangeDate = CURRENT_TIMESTAMP;

There were a lot of performance considerations, all in the vacuum.
The issue with this handlers is that you need to curry them in order to incorporate the argument that you can't name in the props.
This means that the component needs a handler for each and every clickable element. Let's agree that for a few buttons this is not an issue, right?
The problem arises when you are handling tabular data with dozens of columns and thousands of rows. There you notice the impact of creating that many handlers.

The fact is, I only need one.
I set the handler at the table level (or UL or OL...), and when the click happens I can tell which was the clicked cell using data available since ever in the event object:

nativeEvent.target.tagName
nativeEvent.target.parentElement.tagName 
nativeEvent.target.parentElement.rowIndex
nativeEvent.target.cellIndex
nativeEvent.target.textContent

I use the tagname fields to check that the click happened in a valid element, for example ignore clicks in THs ot footers.
The rowIndex and cellIndex give the exact location of the clicked cell.
Textcontent is the text of the clicked cell.

This way I don't need to pass the cell's data to the handler, it can self-service it.
If I needed more data, data that is not to be displayed, I can use the dataset attribute, or hidden elements.
With some simple DOM navigation it's all at hand.
This has been used in HTML since ever, since PCs were much easier to bog.

this should work

header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: X-Requested-With, Content-Type, Origin, Cache-Control, Pragma, Authorization, Accept, Accept-Encoding");

There is no command to do it (like you would do it with MySQL for instance). The number of Redis databases is fixed, and set in the configuration file. By default, you have 16 databases. Each database is identified by a number (not a name).

You can use the following command to know the number of databases:

CONFIG GET databases
1) "databases"
2) "16"

You can use the following command to list the databases for which some keys are defined:

INFO keyspace
# Keyspace
db0:keys=10,expires=0
db1:keys=1,expires=0
db3:keys=1,expires=0

Please note that you are supposed to use the "redis-cli" client to run these commands, not telnet. If you want to use telnet, then you need to run these commands formatted using the Redis protocol.

For instance:

*2
$4
INFO
$8
keyspace

$79
# Keyspace
db0:keys=10,expires=0
db1:keys=1,expires=0
db3:keys=1,expires=0

You can find the description of the Redis protocol here: http://redis.io/topics/protocol

It should run properly at cron also. Please check below things.

1- You are editing proper file to set cron.

2- You have given proper permission(execute permission) to script mean your script is executable.

$("tr.item").each(function() {
  $this = $(this);
  var value = $this.find("span.value").html();
  var quantity = $this.find("input.quantity").val();
});

I'd like to add one additional piece of information since the accepted answer above didn't fix my errors completely.

In my scenario, I have a parent component, which holds a child component. And that child component also contains another component.

So, my parent component's spec file need to have the declaration of the child component, AS WELL AS THE CHILD'S CHILD COMPONENT. That finally fixed the issue for me.

Search Error

An error has occurred: search false You don't have the peais.

Search request is longer.

I had the same issue. My solution was as follows:

1. iOS Simulator -> Hardware -> Keyboard
2. Uncheck "Connect Hardware Keyboard"

Mine was checked because I was using my mac keyboard, but if you make sure it is unchecked the iPhone keyboard will always come up.

This seems to work:

$("#theSelect").change(function(){          
    var value = $("#theSelect option:selected").val();
    var theDiv = $(".is" + value);

    theDiv.slideDown().removeClass("hidden");
    //Add this...
    $("#theSelect option:selected").attr('disabled', 'disabled');
});


$("div a.remove").click(function () {     
    $(this).parent().slideUp(function() { $(this).addClass("hidden"); });
    //...and this.
    $("#theSelect option:disabled").removeAttr('disabled');
});

Arrays in C are converted, in most of the cases, to a pointer to the first element of the array itself. And more in detail arrays passed into functions are always converted into pointers.

Here a quote from K&R2nd:

When an array name is passed to a function, what is passed is the location of the initial element. Within the called function, this argument is a local variable, and so an array name parameter is a pointer, that is, a variable containing an address.

Writing:

void arraytest(int a[])

has the same meaning as writing:

void arraytest(int *a)

So despite you are not writing it explicitly it is as you are passing a pointer and so you are modifying the values in the main.

For more I really suggest reading this.

Moreover, you can find other answers on SO here

Basically, all you have to do is

select ..., (select ... from ... where ...) as ..., ..., from ... where ...

For exemple. You can insert the (select ... from ... where) wherever you want it will be replaced by the corresponding data.

I know that the others exemple (even if each of them are really great :) ) are a bit complicated to understand for the newbies (like me :p) so i hope this "simple" exemple will help some of you guys :)

Here's a simple solution that uses TextView itself with a TextChangedListened added to it:

expressionView = (TextView) findViewById(R.id.expressionView);
expressionView.addTextChangedListener(textAutoResizeWatcher(expressionView, 25, 55));

private TextWatcher textAutoResizeWatcher(final TextView view, final int MIN_SP, final int MAX_SP) {
    return new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {}

        @Override
        public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {}

        @Override
        public void afterTextChanged(Editable editable) {

            final int widthLimitPixels = view.getWidth() - view.getPaddingRight() - view.getPaddingLeft();
            Paint paint = new Paint();
            float fontSizeSP = pixelsToSp(view.getTextSize());
            paint.setTextSize(spToPixels(fontSizeSP));

            String viewText = view.getText().toString();

            float widthPixels = paint.measureText(viewText);

            // Increase font size if necessary.
            if (widthPixels < widthLimitPixels){
                while (widthPixels < widthLimitPixels && fontSizeSP <= MAX_SP){
                    ++fontSizeSP;
                    paint.setTextSize(spToPixels(fontSizeSP));
                    widthPixels = paint.measureText(viewText);
                }
                --fontSizeSP;
            }
            // Decrease font size if necessary.
            else {
                while (widthPixels > widthLimitPixels || fontSizeSP > MAX_SP) {
                    if (fontSizeSP < MIN_SP) {
                        fontSizeSP = MIN_SP;
                        break;
                    }
                    --fontSizeSP;
                    paint.setTextSize(spToPixels(fontSizeSP));
                    widthPixels = paint.measureText(viewText);
                }
            }

            view.setTextSize(fontSizeSP);
        }
    };
}

private float pixelsToSp(float px) {
    float scaledDensity = getResources().getDisplayMetrics().scaledDensity;
    return px/scaledDensity;
}

private float spToPixels(float sp) {
    float scaledDensity = getResources().getDisplayMetrics().scaledDensity;
    return sp * scaledDensity;
}

This approach will increase or decrease the font size as needed to fit the text, respecting the MIN_SP and MAX_SP bounds received as parameters.

Back in the day DIM reserved memory for the array and when memory was limited you had to be careful how you used it. I once wrote (in 1981) a BASIC program on TRS-80 Model III with 48Kb RAM. It wouldn't run on a similar machine with 16Kb RAM until I decreased the array size by changing the DIM statement

The value of the certificate comes mostly from the trust of the internet users in the issuer of the certificate. To that end, Verisign is tough to beat. A certificate says to the client that you are who you say you are, and the issuer has verified that to be true.

You can get a free SSL certificate signed, for example, by StartSSL. This is an improvement on self-signed certificates, because your end-users would stop getting warning pop-ups informing them of a suspicious certificate on your end. However, the browser bar is not going to turn green when communicating with your site over https, so this solution is not ideal.

The cheapest SSL certificate that turns the bar green will cost you a few hundred dollars, and you would need to go through a process of proving the identity of your company to the issuer of the certificate by submitting relevant documents.

Node manages dependencies ie; third party code using package.json so that 3rd party modules names and versions can be kept stable for all installs of the project. This also helps keep the file be light-weight as only actual program code is present in the code repository. Whenever repository is cloned, for it to work(as 3rd party modules may be used in the code), you would need to install all dependencies. Use npm install on CMD within root of the project structure to complete installing all dependencies. This should resolve all dependencies issues if dependencies get properly installed.

with pretty-print format:

import json

with open(path_to_file, 'w') as file:
    json_string = json.dumps(sample, default=lambda o: o.__dict__, sort_keys=True, indent=2)
    file.write(json_string)

Methods that read data into byte slices return the number of bytes read. You should save that number and then use it to create your string. If n is the number of bytes read, your code would look like this:

s := string(byteArray[:n])

To convert the full string, this can be used:

s := string(byteArray[:len(byteArray)])

This is equivalent to:

s := string(byteArray)

If for some reason you don't know n, you could use the bytes package to find it, assuming your input doesn't have a null character embedded in it.

n := bytes.Index(byteArray, []byte{0})

Or as icza pointed out, you can use the code below:

n := bytes.IndexByte(byteArray, 0)

While loop is a bit faster than for loop.

var len = arr.length;
while (len--) {
    // blah blah
}

Use while loop instead

After a long time looking for a way to get git log output the date in the format YYYY-MM-DD in a way that would work in less, I came up with the following format:

%ad%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08

along with the switch --date=iso.

This will print the date in ISO format (a long one), and then print 14 times the backspace character (0x08), which, in my terminal, effectively removes everything after the YYYY-MM-DD part. For example:

git log --date=iso --pretty=format:'%ad%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%aN %s'

This gives something like:

2013-05-24 bruno This is the message of the latest commit.
2013-05-22 bruno This is an older commit.
...

What I did was create an alias named l with some tweaks on the format above. It shows the commit graph to the left, then the commit's hash, followed by the date, the shortnames, the refnames and the subject. The alias is as follows (in ~/.gitconfig):

[alias]
        l = log --date-order --date=iso --graph --full-history --all --pretty=format:'%x08%x09%C(red)%h %C(cyan)%ad%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08%x08 %C(bold blue)%aN%C(reset)%C(bold yellow)%d %C(reset)%s'

The ss.str() temporary is destroyed after initialization of cstr2 is complete. So when you print it with cout, the c-string that was associated with that std::string temporary has long been destoryed, and thus you will be lucky if it crashes and asserts, and not lucky if it prints garbage or does appear to work.

const char* cstr2 = ss.str().c_str();

The C-string where cstr1 points to, however, is associated with a string that still exists at the time you do the cout - so it correctly prints the result.

In the following code, the first cstr is correct (i assume it is cstr1 in the real code?). The second prints the c-string associated with the temporary string object ss.str(). The object is destroyed at the end of evaluating the full-expression in which it appears. The full-expression is the entire cout << ... expression - so while the c-string is output, the associated string object still exists. For cstr2 - it is pure badness that it succeeds. It most possibly internally chooses the same storage location for the new temporary which it already chose for the temporary used to initialize cstr2. It could aswell crash.

cout << cstr            // Prints correctly
    << ss.str().c_str() // Prints correctly
    << cstr2;           // Prints correctly (???)

The return of c_str() will usually just point to the internal string buffer - but that's not a requirement. The string could make up a buffer if its internal implementation is not contiguous for example (that's well possible - but in the next C++ Standard, strings need to be contiguously stored).

In GCC, strings use reference counting and copy-on-write. Thus, you will find that the following holds true (it does, at least on my GCC version)

string a = "hello";
string b(a);
assert(a.c_str() == b.c_str());

The two strings share the same buffer here. At the time you change one of them, the buffer will be copied and each will hold its separate copy. Other string implementations do things different, though.

Regular Expression HOWTO

span() returns both start and end indexes in a single tuple. Since the match method only checks if the RE matches at the start of a string, start() will always be zero. However, the search method of RegexObject instances scans through the string, so the match may not start at zero in that case.

>>> p = re.compile('[a-z]+')
>>> print p.match('::: message')
None
>>> m = p.search('::: message') ; print m
<re.MatchObject instance at 80c9650>
>>> m.group()
'message'
>>> m.span()
(4, 11)

Combine that with:

In Python 2.2, the finditer() method is also available, returning a sequence of MatchObject instances as an iterator.

>>> p = re.compile( ... )
>>> iterator = p.finditer('12 drummers drumming, 11 ... 10 ...')
>>> iterator
<callable-iterator object at 0x401833ac>
>>> for match in iterator:
...     print match.span()
...
(0, 2)
(22, 24)
(29, 31)

you should be able to do something on the order of

for match in re.finditer(r'[a-z]', 'a1b2c3d4'):
   print match.span()

If we need only one column to be numeric

yyz$b <- as.numeric(as.character(yyz$b))

But, if all the columns needs to changed to numeric, use lapply to loop over the columns and convert to numeric by first converting it to character class as the columns were factor.

yyz[] <- lapply(yyz, function(x) as.numeric(as.character(x)))

Both the columns in the OP's post are factor because of the string "n/a". This could be easily avoided while reading the file using na.strings = "n/a" in the read.table/read.csv or if we are using data.frame, we can have character columns with stringsAsFactors=FALSE (the default is stringsAsFactors=TRUE)

Regarding the usage of apply, it converts the dataset to matrix and matrix can hold only a single class. To check the class, we need

lapply(yyz, class)

Or

sapply(yyz, class)

Or check

str(yyz)

If you have two unix timestamps, you can use this function (made a little more verbose for the sake of clarity):

// Calculate number of days between two unix timestamps
// ------------------------------------------------------------
var daysBetween = function(timeStampA, timeStampB) {
    var oneDay = 24 * 60 * 60 * 1000; // hours * minutes * seconds * milliseconds
    var firstDate = new Date(timeStampA * 1000);
    var secondDate = new Date(timeStampB * 1000);
    var diffDays = Math.round(Math.abs((firstDate.getTime() - secondDate.getTime())/(oneDay)));
    return diffDays;
};

Example:

daysBetween(1096580303, 1308713220); // 2455

If you haven't commit the local changes yet since the last pull/clone, you can use:

git checkout *
git pull

checkout will clear your local changes with the last local commit, and pull will sincronize it to the remote repository

Jack M. is right. Do it this way:

>>> class City:
...     def __init__(self, city=None):
...         self.city = city
...     def __repr__(self):
...         if self.city:  return self.city
...         return ''
...
>>> c = City('Berlin')
>>> print c
Berlin
>>> c = City()
>>> print c

>>>

I was wondering if it would be a good idea to have progressive attempts at a process, so you pass this func a process name func_terminate_process "firefox" and it tires things more nicely first, then moves on to kill.

# -- NICE: try to use killall to stop process(s)
killall ${1} > /dev/null 2>&1 ;sleep 10

# -- if we do not see the process, just end the function
pgrep ${1} > /dev/null 2>&1 || return

# -- UGLY: Step trough every pid and use kill -9 on them individually
for PID in $(pidof ${1}) ;do

    echo "Terminating Process: [${1}], PID [${PID}]" 
    kill -9 ${PID} ;sleep 10

    # -- NASTY: If kill -9 fails, try SIGTERM on PID
    if ps -p ${PID} > /dev/null ;then
        echo "${PID} is still running, forcefully terminating with SIGTERM"
        kill -SIGTERM ${PID}  ;sleep 10
    fi

done

# -- If after all that, we still see the process, report that to the screen.
pgrep ${1} > /dev/null 2>&1 && echo "Error, unable to terminate all or any of [${1}]" || echo "Terminate process [${1}] : SUCCESSFUL"

By combining the multicol package and enumitem package packages it is easy to define environments that are multi-column analogues of the enumerate and itemize environments:

\documentclass{article}
\usepackage{enumitem}
\usepackage{multicol}

\newlist{multienum}{enumerate}{1}
\setlist[multienum]{
    label=\alph*),
    before=\begin{multicols}{2},
    after=\end{multicols}
}

\newlist{multiitem}{itemize}{1}
\setlist[multiitem]{
    label=\textbullet,
    before=\begin{multicols}{2},
    after=\end{multicols}
}

\begin{document}

  \textsf{Two column enumerate}
  \begin{multienum}
    \item item 1
    \item item 2
    \item item 3
    \item item 4
    \item item 5
    \item item 6
  \end{multienum}

  \textsf{Two column itemize}
  \begin{multiitem}
    \item item 1
    \item item 2
    \item item 3
    \item item 4
    \item item 5
    \item item 6
  \end{multiitem}

\end{document}

The output is what you would hope for:

I believe the best solution for this, is what I use, and that is a natural css border:

border-right:1px solid;

You might need to take care of padding like:

padding-left: 5px;
padding-right: 5px;

Finally, if you don't want the last li to have that seperating border, give it's last-child "none" in "border-right" like this:

li:last-child{
  border-right:none;
}

Good luck :)

You can always load a json data

here i defined Chart as namespace

 $.getJSON('data.json', function(data){
                Chart.options.series[0].data = data[0].data;
                Chart.options.series[1].data = data[1].data;
                Chart.options.series[2].data = data[2].data;

                var chart = new Highcharts.Chart(Chart.options);

            });

my question: while WHAT is True?

Everything inside the () of the while statement is going to be evaluated as a boolean. Meaning it gets converted into either true or false.

Consider in the statement while(6 > 5)

It first evaluates the expression 6 > 5 which is true so is the same as saying while(true)

Anything that is not FALSE, 0, an emptry string "", null, or undefined is likely to be evaluated to true.

When I first started programming I used to do things like if(foo == true), I didn't realise that was virtually the same thing as if(foo).

So when you say while(true) its like are saying while(true == true)

So to answer you question: While TRUE is True.

git show is more a plumbing command than git log, and has the same formatting options:

git show -s --format=%B SHA1

If it were me doing it I'd use sed:

sed -e '$s/$/\n/' -s *.txt > finalfile.txt

In this sed pattern $ has two meanings, firstly it matches the last line number only (as a range of lines to apply a pattern on) and secondly it matches the end of the line in the substitution pattern.

If your version of sed doesn't have -s (process input files separately) you can do it all as a loop though:

for f in *.txt ; do sed -e '$s/$/\n/' $f ; done > finalfile.txt

(message.length() + 152) / 153

This will give a "rounded up" integer.

Thomas Becker wrote a useful article on the subject here.

There was also this (perhaps simpler) approach that appeared previously on SO: How to correctly implement custom iterators and const_iterators?

Not all cultures use the same format for dates and decimal / currency values.

This will matter for you when you are converting input values (read) that are stored as strings to DateTime, float, double or decimal. It will also matter if you try to format the aforementioned data types to strings (write) for display or storage.

If you know what specific culture that your dates and decimal / currency values will be in ahead of time, you can use that specific CultureInfo property (i.e. CultureInfo("en-GB")). For example if you expect a user input.

The CultureInfo.InvariantCulture property is used if you are formatting or parsing a string that should be parseable by a piece of software independent of the user's local settings.

The default value is CultureInfo.InstalledUICulture so the default CultureInfo is depending on the executing OS's settings. This is why you should always make sure the culture info fits your intention (see Martin's answer for a good guideline).

• CultureInfo.InvariantCulture on StackOverflow
• CultureInfo.InvariantCulture MSDN Article
• Predefined CultureInfo Names

Another working solution for IE specific styling is

<html data-useragent="Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; Trident/6.0)">

And then your selector

html[data-useragent*='MSIE 10.0'] body .my-class{
        margin-left: -0.4em;
    }

If you want speed, try this:

def _timestamp(prec=0):
    t = time.time()
    s = time.strftime("%H:%M:%S", time.localtime(t))
    if prec > 0:
        s += ("%.9f" % (t % 1,))[1:2+prec]
    return s

Where prec is precision -- how many decimal places you want. Please note that the function does not have issues with leading zeros in fractional part like some other solutions presented here.

I understood that you want to remove from the array using a condition and have another array that has items removed from the array. Is right?

How about this?

var review = ['a', 'b', 'c', 'ab', 'bc'];_x000D_
var filtered = [];_x000D_
for(var i=0; i < review.length;) {_x000D_
  if(review[i].charAt(0) == 'a') {_x000D_
    filtered.push(review.splice(i,1)[0]);_x000D_
  }else{_x000D_
    i++;_x000D_

console.log("review", review);_x000D_
console.log("filtered", filtered);

Hope this help...

By the way, I compared 'for-loop' to 'forEach'.

If remove in case a string contains 'f', a result is different.

_x000D_
review.forEach(function(item,i, object) {_x000D_
  if( item.includes('f')) {_x000D_
    filtered.push(object.splice(i,1)[0]);_x000D_
  }_x000D_

_x000D_

And remove by each iteration, also a result is different.

var review = ["of", "concat", "copyWithin", "entries", "every", "fill", "filter", "find", "findIndex", "flatMap", "flatten", "forEach", "includes", "indexOf", "join", "keys", "lastIndexOf", "map", "pop", "push", "reduce", "reduceRight", "reverse", "shift", "slice", "some", "sort", "splice", "toLocaleString", "toSource", "toString", "unshift", "values"];_x000D_

Any algorithm/library that supports a preset dictionary, e.g. zlib.

This way you can prime the compressor with the same kind of text that is likely to appear in the input. If the files are similar in some way (e.g. all URLs, all C programs, all StackOverflow posts, all ASCII-art drawings) then certain substrings will appear in most or all of the input files.

Every compression algorithm will save space if the same substring is repeated multiple times in one input file (e.g. "the" in English text or "int" in C code.)

But in the case of URLs certain strings (e.g. "http://www.", ".com", ".html", ".aspx" will typically appear once in each input file. So you need to share them between files somehow rather than having one compressed occurrence per file. Placing them in a preset dictionary will achieve this.

inside your save button click add this code :

$("#btnSave").click(function (e) {
  e.preventDefault();
  swal("Are you sure?", {
    buttons: {
      yes: {
        text: "Yes",
        value: "yes"
      },
      no: {
        text: "No",
        value: "no"
      }
    }
  }).then((value) => {
    if (value === "yes") {
      // Add Your Custom Code for CRUD
    }
    return false;
  });
});

I wonder same. The API of Assert is not very symmetric; for testing whether objects are the same, it provides assertSame and assertNotSame.

Of course, it is not too long to write:

assertFalse(foo.equals(bar));

With such an assertion, the only informative part of the output is unfortunately the name of the test method, so descriptive message should be formed separately:

String msg = "Expected <" + foo + "> to be unequal to <" + bar +">";
assertFalse(msg, foo.equals(bar));

That is of course so tedious, that it is better to roll your own assertNotEqual. Luckily in future it will maybe be part of the JUnit: JUnit issue 22

This happened to me today. Since I had not changed my system setting since yesterday, I assumed it's predominantly a mysql issue on the system. I managed to fix it in the following way.

1. Open wampserver's mysql log file. This will contain information on why the service threw and error and exited prematurely.

2. In my case, the mysql service failed to start because it could not read a certain tablespace. The specific tablespace was indicated in the log.

3. Failure to read such a file could be because of file permissions or the file being broken. In such a case, mysql stops executing in order to avoid damaging a tablespace file that may be linked to a database you need. Usually, if you have a backup of the database, then it is safe to simply delete this problematic file and restore the database once your mysql service is started again.

4. If you do not have a database backup then you could force the mysql instance to run a recovery by enabling the option in your my.cnf / my.ini file.

innodb_force_recovery = 1

This forces the instance to run the crash recovery.

NOTE: installing a new instance of mysql does not necessarily mean that your databases shall be retained. I suggest you run a nightly backup of your databases if you are working on huge projects.

• For Windows, try:

  NBTSTAT -A 10.100.3.104
  

  or

  ping -a 10.100.3.104
  

• For Linux, try:

  nmblookup -A 10.100.3.104
  

They are almost same.

e.currentTarget is always the element the event is actually bound do. e.target is the element the event originated from, so e.target could be a child of e.currentTarget, or e.target could be === e.currentTarget, depending on how your markup is structured.

You can do it by using the below command:

git clone -b branch_name --single-branch project_url local_folder_to_clone_in

Some cases it does not work-out because there is no problem in your project gradle or android-studio.

Step 1:

Minimum supported Gradle version is 2.14.1. Current version is 2.11. If using the gradle wrapper, try editing the distributionUrl

• Check gradle version in your system gradle -version
• Older version upgrade gradle version brew install gradle

Step 2

• Go to android-studio-> Preference-> Build,Execution,Deployment-> Gradle

• Use default gradle wrapper and un-mark offline work

Step 3

• Check distributionUrl in gradle-wrapper.properties

• Upgrade if older version.

• Clean Project

It will already work, as David pointed out!

If you are using RABL you can configure it as described here to use JSON.pretty_generate:

class PrettyJson
  def self.dump(object)
    JSON.pretty_generate(object, {:indent => "  "})
  end
end

Rabl.configure do |config|
  ...
  config.json_engine = PrettyJson if Rails.env.development?
  ...
end

A problem with using JSON.pretty_generate is that JSON schema validators will no longer be happy with your datetime strings. You can fix those in your config/initializers/rabl_config.rb with:

ActiveSupport::TimeWithZone.class_eval do
  alias_method :orig_to_s, :to_s
  def to_s(format = :default)
    format == :default ? iso8601 : orig_to_s(format)
  end
end

Here is the code for upload to encode and save it to the MySQL

if (!isset($_GET["getfile"])) {
    if ($_FILES["file"]["error"] > 0) {
        echo "Error: " . $_FILES["file"]["error"] . "<br>";
    } else {
        move_uploaded_file($_FILES["file"]["tmp_name"], $_FILES["file"]["name"]);

        $bin_string = file_get_contents($_FILES["file"]["name"]);
        $hex_string = base64_encode($bin_string);
        $mysqli = mysqli_init();

        if (!$mysqli->real_connect('localhost', 'root', '', 'arihant')) {
            die('Connect Error (' . mysqli_connect_errno() . ') ' . mysqli_connect_error());
        }

        $mysqli->query("INSERT INTO upload(image) VALUES ('" . $hex_string . "')");
    }
}

For showing the image use this

echo "<img src='data:image/jpeg;base64, $image' width=300>";

Ehcache is a pretty good solution for this and has a way to peek (getQuiet() is the method) such that it doesn't update the idle timestamp. Internally, Ehcache is implemented with a set of maps, kind of like ConcurrentHashMap, so it has similar kinds of concurrency benefits.

@alvas has a good answer. But again it depends on the nature of the task, for example in your application you want to consider all conjunction e.g. and, or, but, if, while and all determiner e.g. the, a, some, most, every, no as stop words considering all others parts of speech as legitimate, then you might want to look into this solution which use Part-of-Speech Tagset to discard words, Check table 5.1:

import nltk

STOP_TYPES = ['DET', 'CNJ']

text = "some data here "
tokens = nltk.pos_tag(nltk.word_tokenize(text))
good_words = [w for w, wtype in tokens if wtype not in STOP_TYPES]

You can use it like this:

$(document).ready(function(){

    setTimeout("swapImages()",1000);

    function swapImages(){

        var active = $('.active'); 
        var next = ($('.active').next().length > 0) ? $('.active').next() : $('#siteNewsHead img:first');

        active.removeClass('active');
        next.addClass('active');
        setTimeout("swapImages()",1000);
}

});

Through the original question is not exactly about the locale itself all other locale related questions are referencing to this one. That's why I wanted to clarify the issue here. I used this question as a starting point for my own locale switching code and found out that the method is not exactly correct. It works, but only until any configuration change (e.g. screen rotation) and only in that particular Activity. Playing with a code for a while I have ended up with the following approach:

I have extended android.app.Application and added the following code:

public class MyApplication extends Application
{
    private Locale locale = null;

    @Override
    public void onConfigurationChanged(Configuration newConfig)
    {
        super.onConfigurationChanged(newConfig);
        if (locale != null)
        {
            newConfig.locale = locale;
            Locale.setDefault(locale);
            getBaseContext().getResources().updateConfiguration(newConfig, getBaseContext().getResources().getDisplayMetrics());
        }
    }

    @Override
    public void onCreate()
    {
        super.onCreate();

        SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this);

        Configuration config = getBaseContext().getResources().getConfiguration();

        String lang = settings.getString(getString(R.string.pref_locale), "");
        if (! "".equals(lang) && ! config.locale.getLanguage().equals(lang))
        {
            locale = new Locale(lang);
            Locale.setDefault(locale);
            config.locale = locale;
            getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());
        }
    }
}

This code ensures that every Activity will have custom locale set and it will not be reset on rotation and other events.

I have also spent a lot of time trying to make the preference change to be applied immediately but didn't succeed: the language changed correctly on Activity restart, but number formats and other locale properties were not applied until full application restart.

Changes to AndroidManifest.xml

Don't forget to add android:configChanges="layoutDirection|locale" to every activity at AndroidManifest, as well as the android:name=".MyApplication" to the <application> element.

You can use Hibernate Dialect API for Database independence as follow

class SequenceValueGetter {
    private SessionFactory sessionFactory;

    // For Hibernate 3
    public Long getId(final String sequenceName) {
        final List<Long> ids = new ArrayList<Long>(1);

        sessionFactory.getCurrentSession().doWork(new Work() {

Great guide, thank you. Given most instructions here, it almost built for me but I did have one remaining error.

/usr/bin/ld: //usr/local/lib/libglfw3.a(glx_context.c.o): undefined reference to symbol 'dlclose@@GLIBC_2.2.5'
//lib/x86_64-linux-gnu/libdl.so.2: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status

After searching for this error, I had to add -ldl to the command line.

g++ main.cpp -lglfw3 -lX11 -lXrandr -lXinerama -lXi -lXxf86vm -lXcursor -lGL -lpthread -ldl

Then the "hello GLFW" sample app compiled and linked.

I am pretty new to linux so I am not completely certain what exactly this extra library does... other than fix my linking error. I do see that cmd line switch in the post above, however.

You can use crypto-js.

To use crypto-js, you need to load core.js then md5.js .

A list of URLs are here https://cdnjs.com/libraries/crypto-js

cryptojs is also available in zip form here https://code.google.com/archive/p/crypto-js/downloads

There is an answer from answerer 'amal' in 2013, that is similar to this but a)his link to md5.js no longer works b)he didn't load core.js beforehand, which is necessary.

<html>    
  <head> 

    <script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.2/components/core.js"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/crypto-js/3.1.2/rollups/md5.js"></script>

  <script>
     var hash = CryptoJS.MD5("Message");
     console.log(hash);
  </script>

Suppose, You want to add click event like this main.xml

<Button
    android:id="@+id/btn_register"
    android:layout_margin="1dp"
    android:layout_marginLeft="3dp"
    android:layout_marginTop="10dp"
    android:layout_weight="2"
    android:onClick="register"
    android:text="Register"
    android:textColor="#000000"/>

In java file, you have to write a method like this method.

public void register(View view) {
}

Put a black, semitransparent, div on top of it.

I've just setup a spreadsheet that uses Bazaar, with manual checkin/out via TortiseBZR. Given that the topic helped me with the save portion, I wanted to post my solution here.

The solution for me was to create a spreadsheet that exports all modules on save, and removes and re-imports the modules on open. Yes, this could be potentially dangerous for converting existing spreadsheets.

This allows me to edit the macros in the modules via Emacs (yes, emacs) or natively in Excel, and commit my BZR repository after major changes. Because all the modules are text files, the standard diff-style commands in BZR work for my sources except the Excel file itself.

I've setup a directory for my BZR repository, X:\Data\MySheet. In the repo are MySheet.xls and one .vba file for each of my modules (ie: Module1Macros). In my spreadsheet I've added one module that is exempt from the export/import cycle called "VersionControl". Each module to be exported and re-imported must end in "Macros".

Contents of the "VersionControl" module:

Sub SaveCodeModules()

'This code Exports all VBA modules
Dim i%, sName$

With ThisWorkbook.VBProject
    For i% = 1 To .VBComponents.Count
        If .VBComponents(i%).CodeModule.CountOfLines > 0 Then
            sName$ = .VBComponents(i%).CodeModule.Name
            .VBComponents(i%).Export "X:\Tools\MyExcelMacros\" & sName$ & ".vba"
        End If
    Next i
End With

End Sub

Sub ImportCodeModules()

With ThisWorkbook.VBProject
    For i% = 1 To .VBComponents.Count

        ModuleName = .VBComponents(i%).CodeModule.Name

        If ModuleName <> "VersionControl" Then
            If Right(ModuleName, 6) = "Macros" Then
                .VBComponents.Remove .VBComponents(ModuleName)
                .VBComponents.Import "X:\Data\MySheet\" & ModuleName & ".vba"
           End If
        End If
    Next i
End With

End Sub

Next, we have to setup event hooks for open / save to run these macros. In the code viewer, right click on "ThisWorkbook" and select "View Code". You may have to pull down the select box at the top of the code window to change from "(General)" view to "Workbook" view.

Contents of "Workbook" view:

Private Sub Workbook_Open()

ImportCodeModules

End Sub

Private Sub Workbook_BeforeSave(ByVal SaveAsUI As Boolean, Cancel As Boolean)

SaveCodeModules

End Sub

I'll be settling into this workflow over the next few weeks, and I'll post if I have any problems.

Thanks for sharing the VBComponent code!

I assume you want lowercase the text. Solution is pretty simple:

ggVGu

Explanation:

1. gg - goes to first line of text
2. V - turns on Visual selection, in line mode
3. G - goes to end of file (at the moment you have whole text selected)
4. u - lowercase selected area

If you're ever dynamically generating page content or loading content through AJAX, the following example is really the way you should go:

1. It prevents double binding in the case where the script is loaded more than once, such as in an AJAX request.
2. The bind lives on the body of the document, so regardless of what elements are added, moved, removed and re-added, all descendants of body matching the selector specified will retain proper binding.

The Code:

// Define the element we wish to bind to.
var bind_to = ':input';

// Prevent double-binding.
$(document.body).off('change', bind_to);

// Bind the event to all body descendants matching the "bind_to" selector.
$(document.body).on('change keyup', bind_to, function(event) {
    alert('something happened!');
});

Please notice! I'm making use of $.on() and $.off() rather than other methods for several reasons:

1. $.live() and $.die() are deprecated and have been omitted from more recent versions of jQuery.
2. I'd either need to define a separate function (therefore cluttering up the global scope,) and pass the function to both $.change() and $.keyup() separately, or pass the same function declaration to each function called; Duplicating logic... Which is absolutely unacceptable.
3. If elements are ever added to the DOM, $.bind() does not dynamically bind to elements as they are created. Therefore if you bind to :input and then add an input to the DOM, that bind method is not attached to the new input. You'd then need to explicitly un-bind and then re-bind to all elements in the DOM (otherwise you'll end up with binds being duplicated). This process would need to be repeated each time an input was added to the DOM.

If you don't care about checking the validity of the certificate just add the --no-check-certificate option on the wget command-line. This worked well for me.

NOTE: This opens you up to man-in-the-middle (MitM) attacks, and is not recommended for anything where you care about security.

There are lots of data types you can mention while creating model, some examples are:

:primary_key, :string, :text, :integer, :float, :decimal, :datetime, :timestamp, :time, :date, :binary, :boolean, :references

syntax:

field_type:data_type

According to this thread on MVC4 css bundling and image references, if you define your bundle as:

bundles.Add(new StyleBundle("~/Content/css/jquery-ui/bundle")
                   .Include("~/Content/css/jquery-ui/*.css"));

Where you define the bundle on the same path as the source files that made up the bundle, the relative image paths will still work. The last part of the bundle path is really the file name for that specific bundle (i.e., /bundle can be any name you like).

This will only work if you are bundling together CSS from the same folder (which I think makes sense from a bundling perspective).

Update

As per the comment below by @Hao Kung, alternatively this may now be achieved by applying a CssRewriteUrlTransformation (Change relative URL references to CSS files when bundled).

NOTE: I have not confirmed comments regarding issues with rewriting to absolute paths within a virtual directory, so this may not work for everyone (?).

bundles.Add(new StyleBundle("~/Content/css/jquery-ui/bundle")
                   .Include("~/Content/css/jquery-ui/*.css",
                    new CssRewriteUrlTransform()));

Try the where command on Windows 2003 or later (or Windows 2000/XP if you've installed a Resource Kit).

BTW, this received more answers in other questions:

Is there an equivalent of 'which' on Windows?

PowerShell equivalent to Unix which command?

This bash script loop ends if the process does not exist, or it's a zombie.

PID=<pid to watch>
while s=`ps -p $PID -o s=` && [[ "$s" && "$s" != 'Z' ]]; do
    sleep 1
done

EDIT: The above script was given below by Rockallite. Thanks!

My orignal answer below works for Linux, relying on procfs i.e. /proc/. I don't know its portability:

while [[ ( -d /proc/$PID ) && ( -z `grep zombie /proc/$PID/status` ) ]]; do
    sleep 1
done

It's not limited to shell, but OS's themselves do not have system calls to watch non-child process termination.

Array initializer support for type inference were changed in Visual Basic 10 vs Visual Basic 9.

In previous version of VB it was required to put empty parens to signify an array. Also, it would define the array as object array unless otherwise was stated:

' Integer array
Dim i as Integer() = {1, 2, 3, 4} 

' Object array
Dim o() = {1, 2, 3}

For me, this issue was slightly different than other answers, as I was only receiving 404s on OPTIONS, yet I already had OPTIONS specifically stated in my Integrated Extensionless URL Handler options. Very confusing.

1. As others have stated, runAllManagedModulesForAllRequests="true" in the modules node is an easy way to blanket-fix most Web API 404 issues - although I prefer @DavidAndroidDev 's answer which is much less intrusive. But there was something additional in my case.
2. Unfortunately, I had this set in IIS under Request Filtering in the site:

By adding the following security node to the web.config was necessary to knock that out - full system.webserver included for context:

  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
      <remove name="WebDAVModule" />
    </modules>
    <handlers>
      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
      <remove name="OPTIONSVerbHandler" />
      <remove name="TRACEVerbHandler" />
      <remove name="WebDAV" />
      <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>
    <security>
      <requestFiltering>
        <verbs>
          <remove verb="OPTIONS" />
        </verbs>
      </requestFiltering>
    </security>
  </system.webServer>

Although it's not the perfect answer for this question, it is the first result for "IIS OPTIONS 404" on Google, so I hope this helps someone out; cost me an hour today.

Solved! The call build job: project, parameters: params fails with an error java.lang.UnsupportedOperationException: must specify $class with an implementation of interface java.util.List when params = [:]. Replacing it with params = null solved the issue. Here the working code below.

def doCopyMibArtefactsHere(projectName) {
    step ([
        $class: 'CopyArtifact',
        projectName: projectName,
        filter: '**/**.mib',
        fingerprintArtifacts: true, 
        flatten: true
    ]);
}

def BuildAndCopyMibsHere(projectName, params = null) {
    build job: project, parameters: params
    doCopyMibArtefactsHere(projectName)
}
node { 
    stage('Prepare Mib'){
        BuildAndCopyMibsHere('project1')
    }
}

Use apaches startup debug tool from command:

httpd.exe -e warn

1. press Win+R
2. type cmd and press enter
3. goto directory which contains your apache httpd.exe file. for example if your wamp is installed in e:\wamp type cd /d e:\wamp\bin\apache\ApacheX.X.X\bin in cmd and press enter.
4. type httpd.exe -e warn (or httpd.exe -e debug for more details) to see error message about problem which is prohibiting apache to start.

You can combine the find command and the ls command. Use the path (.) and selector (*) to narrow down the files you're after. Surround the find command in back quotes. The argument to -name is doublequote star doublequote in case you can't read it.

ls -lart `find . -type f -name "*" `

lapply(your_dataframe, class) gives you something like:

$tikr [1] "factor"

$Date [1] "Date"

$Open [1] "numeric"

$High [1] "numeric"

... etc.

I'm going to agree with shodanex, it looks like you're prematurely trying to optimize something that isn't yet problematic. Unless you know sockets are going to be a bottleneck, I'd just use them.

A lot of people who swear by named pipes find a little savings (depending on how well everything else is written), but end up with code that spends more time blocking for an IPC reply than it does doing useful work. Sure, non-blocking schemes help this, but those can be tricky. Spending years bringing old code into the modern age, I can say, the speedup is almost nil in the majority of cases I've seen.

If you really think that sockets are going to slow you down, then go out of the gate using shared memory with careful attention to how you use locks. Again, in all actuality, you might find a small speedup, but notice that you're wasting a portion of it waiting on mutual exclusion locks. I'm not going to advocate a trip to futex hell (well, not quite hell anymore in 2015, depending upon your experience).

Pound for pound, sockets are (almost) always the best way to go for user space IPC under a monolithic kernel .. and (usually) the easiest to debug and maintain.

I discovered quite by accident (I was working with images at the time) that the box-shadow, border-radius and transitions work quite well with the bog-standard audio tag player. I have this working in Chrome, FF and Opera.

audio:hover, audio:focus, audio:active
{
-webkit-box-shadow: 15px 15px 20px rgba(0,0, 0, 0.4);
-moz-box-shadow: 15px 15px 20px rgba(0,0, 0, 0.4);
box-shadow: 15px 15px 20px rgba(0,0, 0, 0.4);
-webkit-transform: scale(1.05);
-moz-transform: scale(1.05);
transform: scale(1.05);
}

with:-

audio
{
-webkit-transition:all 0.5s linear;
-moz-transition:all 0.5s linear;
-o-transition:all 0.5s linear;
transition:all 0.5s linear;
-moz-box-shadow: 2px 2px 4px 0px #006773;
-webkit-box-shadow:  2px 2px 4px 0px #006773;
box-shadow: 2px 2px 4px 0px #006773;
-moz-border-radius:7px 7px 7px 7px ;
-webkit-border-radius:7px 7px 7px 7px ;
border-radius:7px 7px 7px 7px ;
}

I grant you it only "tarts it up a bit", but it makes them a sight more exciting than what's already there, and without doing MAJOR fannying about in JS.

NOT available in IE, unfortunately (not yet supporting the transition bit), but it seems to degrade nicely.

you're missing group nested controls with formGroupName directive

<div class="panel-body" formGroupName="address">
  <div class="form-group">

You could use the method

- (NSString *)stringByReplacingOccurrencesOfString:(NSString *)target 
                                        withString:(NSString *)replacement

...to get a new string with a substring replaced (See NSString documentation for others)

Example use

NSString *str = @"This is a string";

str = [str stringByReplacingOccurrencesOfString:@"string"
                                     withString:@"duck"];

Proper use of RuntimeException?

From Unchecked Exceptions -- The Controversy:

If a client can reasonably be expected to recover from an exception, make it a checked exception. If a client cannot do anything to recover from the exception, make it an unchecked exception.

Note that an unchecked exception is one derived from RuntimeException and a checked exception is one derived from Exception.

Why throw a RuntimeException if a client cannot do anything to recover from the exception? The article explains:

Runtime exceptions represent problems that are the result of a programming problem, and as such, the API client code cannot reasonably be expected to recover from them or to handle them in any way. Such problems include arithmetic exceptions, such as dividing by zero; pointer exceptions, such as trying to access an object through a null reference; and indexing exceptions, such as attempting to access an array element through an index that is too large or too small.

to overcome this kind of problem follow the steps below:

• open command prompt.
• c:\Users\CGITS_04> netstat -o -n -a | findstr 0.0:80
• then you can see a list of process that is currently using port 80.
• open task manager->search the process-> select and end process.
• Now open eclipse and start tomcat.
• happy coding!

UPDATE

In Android Studio AVD:

1. Open AVD Manager:

2. Add/Edit AVD:

3. Click Advanced Settings in the bottom of the screen:

4. Set your camera of choice as the front/back cameras:

A procedure can't return a table as such. However you can select from a table in a procedure and direct it into a table (or table variable) like this:

create procedure p_x
as
begin
declare @t table(col1 varchar(10), col2 float, col3 float, col4 float)
insert @t values('a', 1,1,1)
insert @t values('b', 2,2,2)

select * from @t
end
go

declare @t table(col1 varchar(10), col2 float, col3 float, col4 float)
insert @t
exec p_x

select * from @t

Here is an alternative. Create a generic exception that takes a status code and a message. Then create an exception handler. Use the exception handler to retrieve the information out of the exception and return to the caller of the service.

http://javaninja.net/2016/06/throwing-exceptions-messages-spring-mvc-controller/

public class ResourceException extends RuntimeException {

    private HttpStatus httpStatus = HttpStatus.INTERNAL_SERVER_ERROR;

    public HttpStatus getHttpStatus() {
        return httpStatus;
    }

    /**
     * Constructs a new runtime exception with the specified detail message.
     * The cause is not initialized, and may subsequently be initialized by a
     * call to {@link #initCause}.
     * @param message the detail message. The detail message is saved for later retrieval by the {@link #getMessage()}
     *                method.
     */
    public ResourceException(HttpStatus httpStatus, String message) {
        super(message);
        this.httpStatus = httpStatus;
    }
}

Then use an exception handler to retrieve the information and return it to the service caller.

@ControllerAdvice
public class ExceptionHandlerAdvice { 

    @ExceptionHandler(ResourceException.class)
    public ResponseEntity handleException(ResourceException e) {
        // log exception 
        return ResponseEntity.status(e.getHttpStatus()).body(e.getMessage());
    }         
} 

Then create an exception when you need to.

throw new ResourceException(HttpStatus.NOT_FOUND, "We were unable to find the specified resource.");

Use the substring method of the String class :

String removeCurrency=amount.getText().toString().substring(3);

If you are using ubuntu you can take update

sudo apt-get update

And install extension in case of php 5.6

sudo apt-get install php5.6-intl

And in case of php 7.0

sudo apt-get install php7.0-intl

And restart your apache after

sudo service apache2 restart

If you are using xampp then remove semicolon ( ; ) in xampp/php/php.ini from below line

 ;extension=php_intl.dll

And then restart your xampp.

You can always call an asynchronous method without await if you simply want to fire and forget. But it becomes tricky when you need to wait for the result and do something with the result.

I had to call an async method in a property setter in an ASP.NET Core Blazor Server Side component. I needed to get a result from that async method and do something else.

I was stuck as I could not even use the Task.Result property in Blazor context.

So, I solved the problem by calling the .ContinueWith method which worked great. Here is a sample snippet I used.

    public bool AProperty
    {
        get => _aProperty;
        set
        {
            if (_aProperty!= value)
            {
                _aProperty= value;

                myService.UpdateAReocrdAsync().ContinueWith(previousTask =>
                {
                    int numberOfRowsAffected = previousTask.Result;
                   
                    if (numberOfRowsAffected > 0)
                    {
                        toastService.ShowSuccess($"Total {numberOfRowsAffected} rows updated.");
                    }
                    else
                    {
                        toastService.ShowError("No record was updated.");
                    }
                });
            }
        }
    }

Using the ternary operator is possible like following.[disabled] internally required true or false for its operation.

<button type="button" 
  [disabled]="(testVariable1 != 0 || testVariable2!=0)? true:false"
  mat-button>Button</button>

Try using the Dictionary Object or the Collection Object.

"Upstream" would refer to the main repo that other people will be pulling from, e.g. your GitHub repo. The -u option automatically sets that upstream for you, linking your repo to a central one. That way, in the future, Git "knows" where you want to push to and where you want to pull from, so you can use git pull or git push without arguments. A little bit down, this article explains and demonstrates this concept.

I was facing similar issue with openCV on the python:3.7-slim docker box. Following did the trick for me :

apt-get install build-essential libglib2.0-0 libsm6 libxext6 libxrender-dev

Please see if this helps !

You shouldn't be closing the serial port in Python between writing and reading. There is a chance that the port is still closed when the Arduino responds, in which case the data will be lost.

while running:  
    # Serial write section
    setTempCar1 = 63
    setTempCar2 = 37
    setTemp1 = str(setTempCar1)
    setTemp2 = str(setTempCar2)
    print ("Python value sent: ")
    print (setTemp1)
    ard.write(setTemp1)
    time.sleep(6) # with the port open, the response will be buffered 
                  # so wait a bit longer for response here

    # Serial read section
    msg = ard.read(ard.inWaiting()) # read everything in the input buffer
    print ("Message from arduino: ")
    print (msg)

The Python Serial.read function only returns a single byte by default, so you need to either call it in a loop or wait for the data to be transmitted and then read the whole buffer.

On the Arduino side, you should consider what happens in your loop function when no data is available.

void loop()
{
  // serial read section
  while (Serial.available()) // this will be skipped if no data present, leading to
                             // the code sitting in the delay function below
  {
    delay(30);  //delay to allow buffer to fill 
    if (Serial.available() >0)
    {
      char c = Serial.read();  //gets one byte from serial buffer
      readString += c; //makes the string readString
    }
  }

Instead, wait at the start of the loop function until data arrives:

void loop()
{
  while (!Serial.available()) {} // wait for data to arrive
  // serial read section
  while (Serial.available())
  {
    // continue as before

EDIT 2

Here's what I get when interfacing with your Arduino app from Python:

>>> import serial
>>> s = serial.Serial('/dev/tty.usbmodem1411', 9600, timeout=5)
>>> s.write('2')
1
>>> s.readline()
'Arduino received: 2\r\n'

So that seems to be working fine.

In testing your Python script, it seems the problem is that the Arduino resets when you open the serial port (at least my Uno does), so you need to wait a few seconds for it to start up. You are also only reading a single line for the response, so I've fixed that in the code below also:

#!/usr/bin/python
import serial
import syslog
import time

#The following line is for serial over GPIO
port = '/dev/tty.usbmodem1411' # note I'm using Mac OS-X


ard = serial.Serial(port,9600,timeout=5)
time.sleep(2) # wait for Arduino

i = 0

while (i < 4):
    # Serial write section

    setTempCar1 = 63
    setTempCar2 = 37
    ard.flush()
    setTemp1 = str(setTempCar1)
    setTemp2 = str(setTempCar2)
    print ("Python value sent: ")
    print (setTemp1)
    ard.write(setTemp1)
    time.sleep(1) # I shortened this to match the new value in your Arduino code

    # Serial read section
    msg = ard.read(ard.inWaiting()) # read all characters in buffer
    print ("Message from arduino: ")
    print (msg)
    i = i + 1
else:
    print "Exiting"
exit()

Here's the output of the above now:

$ python ardser.py

63

No need to use a macro. Supposing your first string is in A1.

=RIGHT(A1, 4)

Drag this down and you will get your four last characters.

Edit: To be sure, if you ever have sequences like 'ABC DEF' and want the last four LETTERS and not CHARACTERS you might want to use trimspaces()

=RIGHT(TRIMSPACES(A1), 4)

Edit: As per brettdj's suggestion, you may want to check that your string is actually 4-character long or more:

=IF(TRIMSPACES(A1)>=4, RIGHT(TRIMSPACES(A1), 4), TRIMSPACES(A1))

You can amend your !DOCTYPE declaration (i.e. DTD) to allow it, so that the [XML] document will still be valid:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"
[
  <!ATTLIST tag myAttri CDATA #IMPLIED>
]>

#IMPLIED means it is an optional attribute, or you could use #REQUIRED, etc.

More information is in DTD - Attributes.

As of Python 3.7, datetime.datetime.fromisoformat() can handle your format:

>>> import datetime
>>> datetime.datetime.fromisoformat('2012-11-01T04:16:13-04:00')
datetime.datetime(2012, 11, 1, 4, 16, 13, tzinfo=datetime.timezone(datetime.timedelta(days=-1, seconds=72000)))

In older Python versions you can't, not without a whole lot of painstaking manual timezone defining.

Python does not include a timezone database, because it would be outdated too quickly. Instead, Python relies on external libraries, which can have a far faster release cycle, to provide properly configured timezones for you.

As a side-effect, this means that timezone parsing also needs to be an external library. If dateutil is too heavy-weight for you, use iso8601 instead, it'll parse your specific format just fine:

>>> import iso8601
>>> iso8601.parse_date('2012-11-01T04:16:13-04:00')
datetime.datetime(2012, 11, 1, 4, 16, 13, tzinfo=<FixedOffset '-04:00'>)

iso8601 is a whopping 4KB small. Compare that tot python-dateutil's 148KB.

As of Python 3.2 Python can handle simple offset-based timezones, and %z will parse -hhmm and +hhmm timezone offsets in a timestamp. That means that for a ISO 8601 timestamp you'd have to remove the : in the timezone:

>>> from datetime import datetime
>>> iso_ts = '2012-11-01T04:16:13-04:00'
>>> datetime.strptime(''.join(iso_ts.rsplit(':', 1)), '%Y-%m-%dT%H:%M:%S%z')
datetime.datetime(2012, 11, 1, 4, 16, 13, tzinfo=datetime.timezone(datetime.timedelta(-1, 72000)))

The lack of proper ISO 8601 parsing is being tracked in Python issue 15873.

I wanted to check on multiple file types and was to lazy to calculate the total by hand. So I use this now to get the total in one go.

find . -name '*.js' -or -name '*.php' | xargs wc -l | grep 'total'  | awk '{ SUM += $1; print $1} END { print "Total text lines in PHP and JS",SUM }'

79351
15318
Total text lines in PHP and JS 94669

This allows you to chain multiple extension types you wish to filter on. Just add them in the -name '*.js' -or -name '*.php' part, and possibly modify the otuput message to your liking.

In P4V click View > Workspaces

If the workspace to be deleted is not visible in the list you may have to uncheck the box Show only workspaces available for use on this computer

Right-click the workspace to be deleted and choose Edit Workspace 'My_workspace'

On the Advanced tab uncheck the box Locked: only the owner can edit workspace settings > then click OK

Now back on the Workspaces tab of Perforce right-click the workspace to be deleted and choose Delete Workspace 'My_workspace'

P4V should remove the item from the drop-down list when clicking on it.

There is a case where a previously deleted workspace remains in the drop-down list, and P4V displays the following error:

P4V Workspace Switch Error. This workspace cannot be used on this computer either because the host field does not match your computer name or the workspace root cannot be used on this computer.

If this error occurs, the workspace(possibly on another host) may have only been unloaded. Click the P4V Workspaces Recycle bin

In the resulting Unloaded Workspaces window right-click the offending workspace and choose Delete Workspace 'My_workspace'. P4V should now remove the workspace item from the drop-down list.

The second way is a tad more efficient, but a much better way is to execute them in batches:

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (
        Connection connection = dataSource.getConnection();
        PreparedStatement statement = connection.prepareStatement(SQL);
    ) {
        for (Entity entity : entities) {
            statement.setObject(1, entity.getSomeProperty());
            // ...

            statement.addBatch();
        }

        statement.executeBatch();
    }
}

You're however dependent on the JDBC driver implementation how many batches you could execute at once. You may for example want to execute them every 1000 batches:

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (
        Connection connection = dataSource.getConnection();
        PreparedStatement statement = connection.prepareStatement(SQL);
    ) {
        int i = 0;

        for (Entity entity : entities) {
            statement.setObject(1, entity.getSomeProperty());
            // ...

            statement.addBatch();
            i++;

            if (i % 1000 == 0 || i == entities.size()) {
                statement.executeBatch(); // Execute every 1000 items.
            }
        }
    }
}

As to the multithreaded environments, you don't need to worry about this if you acquire and close the connection and the statement in the shortest possible scope inside the same method block according the normal JDBC idiom using try-with-resources statement as shown in above snippets.

If those batches are transactional, then you'd like to turn off autocommit of the connection and only commit the transaction when all batches are finished. Otherwise it may result in a dirty database when the first bunch of batches succeeded and the later not.

public void executeBatch(List<Entity> entities) throws SQLException { 
    try (Connection connection = dataSource.getConnection()) {
        connection.setAutoCommit(false);

        try (PreparedStatement statement = connection.prepareStatement(SQL)) {
            // ...

            try {
                connection.commit();
            } catch (SQLException e) {
                connection.rollback();
                throw e;
            }
        }
    }
}

You should be able to do this like (as you're using the query api):

Entrant.where("pincode").ne(null)

... which will result in a mongo query resembling:

entrants.find({ pincode: { $ne: null } })

A few links that might help:

• The mongoose query api
• The docs for mongo query operators

I would suggest to use gradle.build file.

1. Add a src/androidTest/java directory for the tests (Like Chris starts to explain)

2. Open gradle.build file and specify there:

   android {
   
       compileSdkVersion rootProject.compileSdkVersion
       buildToolsVersion rootProject.buildToolsVersion
   
       sourceSets {
   
           androidTest {
               java.srcDirs = ['androidTest/java']
           }
       }
   }
   

3. Press "Sync Project with Gradle file" (at the top panel). You should see now a folder "java" (inside "androidTest") is a green color.

4. Now You are able to create there any test files and execute they.

Microsoft has also defined UINT_PTR and INT_PTR for integers that are the same size as a pointer.

Here is a list of Microsoft specific types - it's part of their driver reference, but I believe it's valid for general programming as well.

Remove all forward slash occurrences with blank char in Javascript.

modelData = modelData.replace(/\//g, '');

Readonly will allow the user to copy text from it. Disabled will not.

Look at ?par for the various graphics parameters.

In general cex controls size, col controls colour. If you want to control the colour of a label, the par is col.lab, the colour of the axis annotations col.axis, the colour of the main text, col.main etc. The names are quite intuitive, once you know where to begin.

For example

x <- 1:10
y <- 1:10

plot(x , y,xlab="x axis", ylab="y axis",  pch=19, col.axis = 'blue', col.lab = 'red', cex.axis = 1.5, cex.lab = 2)

If you need to change the colour / style of the surrounding box and axis lines, then look at ?axis or ?box, and you will find that you will be using the same parameter names within calls to box and axis.

You have a lot of control to make things however you wish.

eg

plot(x , y,xlab="x axis", ylab="y axis",  pch=19,  cex.lab = 2, axes = F,col.lab = 'red')
box(col = 'lightblue')
axis(1, col = 'blue', col.axis = 'purple', col.ticks = 'darkred', cex.axis = 1.5, font = 2, family = 'serif')
axis(2, col = 'maroon', col.axis = 'pink', col.ticks = 'limegreen', cex.axis = 0.9, font =3, family = 'mono')

Which is seriously ugly, but shows part of what you can control

Use this command : (Jarsigner is in your Java bin folder goto java->jdk->bin path in cmd prompt)

$ jarsigner -verify my_signed.apk

If the .apk is signed properly, Jarsigner prints "jar verified"

You are passing a target array of shape (x-dim, y-dim) while using as loss categorical_crossentropy. categorical_crossentropy expects targets to be binary matrices (1s and 0s) of shape (samples, classes). If your targets are integer classes, you can convert them to the expected format via:

from keras.utils import to_categorical
y_binary = to_categorical(y_int)

Alternatively, you can use the loss function sparse_categorical_crossentropy instead, which does expect integer targets.

model.compile(loss='sparse_categorical_crossentropy', optimizer='adam', metrics=['accuracy'])

I've seen some nice AngularJS charting solutions that make use of Highcharts. There's a highcharts-ng directive on GitHub to make AngularJS integration easier, and some examples on JSFiddle to give you a quick taste of what's possible.

You set up the chart on the JS side like this:

$scope.chart = {
    options: {
        chart: {
            type: 'bar'
        }
    },
    series: [{
        data: [10, 15, 12, 8, 7]
    }],
    title: {
        text: 'Hello'
    },
    loading: false
}

And then refer to it in the HTML like this:

<highchart id="chart1" config="chart"></highchart>

Usage/licensing warning: Highcharts is available for free under the Creative Commons license for non-commercial use. If you're looking for charting options in a for-profit/commercial scenario, you'll need to buy the product or look elsewhere.

On a related note: the java compiler uses int to represent boolean since JVM has a limited support for the boolean type.See Section 3.3.4 The boolean type.

In JVM, the integer zero represents false, and any non-zero integer represents true (Source : Inside Java Virtual Machine by Bill Venners)

If you are using Backbone and React, I'd recommend one of the following,

• Backbone.React.Component
• react.backbone

They both help integrate Backbone models and collections with React views. You can use Backbone events just like you do with Backbone views. I've dabbled in both and didn't see much of a difference except one is a mixin and the other changes React.createClass to React.createBackboneClass.

In response to some comments asking questions about the behaviour of Arrays.asList() since Java 8:

    int[] arr1 = {1,2,3};
    /* 
       Arrays are objects in Java, internally int[] will be represented by 
       an Integer Array object which when printed on console shall output
       a pattern such as 
       [I@address for 1-dim int array,
       [[I@address for 2-dim int array, 
       [[F@address for 2-dim float array etc. 
   */
    System.out.println(Arrays.asList(arr1)); 

    /* 
       The line below results in Compile time error as Arrays.asList(int[] array)
       returns List<int[]>. The returned list contains only one element 
       and that is the int[] {1,2,3} 
    */
    // List<Integer> list1 = Arrays.asList(arr1);

    /* 
       Arrays.asList(arr1) is  Arrays$ArrayList object whose only element is int[] array
       so the line below prints [[I@...], where [I@... is the array object.
    */
    System.out.println(Arrays.asList(arr1)); 

    /* 
     This prints [I@..., the actual array object stored as single element 
     in the Arrays$ArrayList object. 
    */
    System.out.println(Arrays.asList(arr1).get(0));

    // prints the contents of array [1,2,3]
    System.out.println(Arrays.toString(Arrays.asList(arr1).get(0)));

    Integer[] arr2 = {1,2,3};
    /* 
     Arrays.asList(arr) is  Arrays$ArrayList object which is 
     a wrapper list object containing three elements 1,2,3.
     Technically, it is pointing to the original Integer[] array 
    */
    List<Integer> list2 = Arrays.asList(arr2);

    // prints the contents of list [1,2,3]
    System.out.println(list2);

I'll try to explain it visually:

Go to https://dev.twitter.com/apps to list all your apps. Click on the desired app to get its consumer and secret key. If you didnt yet created any app then follow https://dev.twitter.com/apps/new to create new one.

For more general boolean functions that you would like to use as a filter and that depend on more than one column, you can use:

df = df[df[['col_1','col_2']].apply(lambda x: f(*x), axis=1)]

where f is a function that is applied to every pair of elements (x1, x2) from col_1 and col_2 and returns True or False depending on any condition you want on (x1, x2).

There is an open issue to only print this warning if there was actually something sanitized: https://github.com/angular/angular/pull/10272

I didn't read in detail when this warning is printed when nothing was sanitized.
