The aspect ratio for a Facebook post image is 41:20.

To find the appropriate widths and height for your photo, you can use the Aspect Ratio Calculator.

Here you can select different ratios under “Common ratios:” which includes the option “1200 x 630 (Facebook)". So if the width of your photo is 1800, plug that number into the “W2” slot and it will tell you what the respective height should be.

Remember that when you restart the database by removing .lock files by force, the data might get corrupted. Your server shouldn't be considered "healthy" if you restarted the server that way.

To amend the situation, either run

mongod --repair

or

> db.repairDatabase();    

in the mongo shell to bring your database back to "healthy" state.

If I don't know the size up front, I use an arraylist instead of an array.

$al = New-Object System.Collections.ArrayList
for($i=0; $i -lt 5; $i++)
{
    $al.Add($i)
}

Unfortunately the JSON specification does not allow a trailing comma. There are a few browsers that will allow it, but generally you need to worry about all browsers.

In general I try turn the problem around, and add the comma before the actual value, so you end up with code that looks like this:

s.append("[");
for (i = 0; i < 5; ++i) {
  if (i) s.append(","); // add the comma only if this isn't the first entry
  s.appendF("\"%d\"", i);
}
s.append("]");

That extra one line of code in your for loop is hardly expensive...

Another alternative I've used when output a structure to JSON from a dictionary of some form is to always append a comma after each entry (as you are doing above) and then add a dummy entry at the end that has not trailing comma (but that is just lazy ;->).

Doesn't work well with an array unfortunately.

Another option is to use the case-insensitive flag i, then there's no need for the extra character range A-Z.

var reg = /^[a-z]+$/i;
console.log( reg.test("somethingELSE") ); //true
console.log( "somethingELSE".match(reg)[0] ); //"somethingELSE"

Here's a DEMO on how this regex works with test() and match().

There are many options:

rspec spec                           # All specs
rspec spec/models                    # All specs in the models directory
rspec spec/models/a_model_spec.rb    # All specs in the some_model model spec
rspec spec/models/a_model_spec.rb:nn # Run the spec that includes line 'nn'
rspec -e"text from a test"           # Runs specs that match the text
rspec spec --tag focus               # Runs specs that have :focus => true
rspec spec --tag focus:special       # Run specs that have :focus => special
rspec spec --tag focus ~skip         # Run tests except those with :focus => true

To add to add to the previous answer, there is even a fourth way that can be used

import codecs
encoded4 = codecs.encode(original, 'utf-8')
print(encoded4)

It works with Android Studio 1.2 + OpenCV-2.4.11-android-sdk (.zip), too.

Just do the following:

1) Follow the answer that starts with "You can do this very easily in Android Studio. Follow the steps below to add OpenCV in your project as library." by TGMCians.

2) Modify in the <yourAppDir>\libraries\opencv folder your newly created build.gradle to (step 4 in TGMCians' answer, adapted to OpenCV2.4.11-android-sdk and using gradle 1.1.0):

apply plugin: 'android-library'

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.1.0'
    }
}

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 21
        versionCode 2411
        versionName "2.4.11"
    }

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            res.srcDirs = ['res']
            aidl.srcDirs = ['src']
        }
    }
}

3) *.so files that are located in the directories "armeabi", "armeabi-v7a", "mips", "x86" can be found under (default OpenCV-location): ..\OpenCV-2.4.11-android-sdk\OpenCV-android-sdk\sdk\native\libs (step 9 in TGMCians' answer).

Enjoy and if this helped, please give a positive reputation. I need 50 to answer directly to answers (19 left) :)

A good idea is to set all of the "" (blank cells) to NA before any further analysis.

If you are reading your input from a file, it is a good choice to cast all "" to NAs:

foo <- read.table(file="Your_file.txt", na.strings=c("", "NA"), sep="\t") # if your file is tab delimited

If you have already your table loaded, you can act as follows:

foo[foo==""] <- NA

Then to keep only rows with no NA you may just use na.omit():

foo <- na.omit(foo)

Or to keep columns with no NA:

foo <- foo[, colSums(is.na(foo)) == 0] 

Say your variable is myNode, you can do myNode.value to retrieve the value of input elements.

Firebug has a "DOM" tab which shows useful DOM attributes.

Also see the mozilla page for a reference: https://developer.mozilla.org/en-US/docs/DOM/HTMLInputElement

If you want an alternative to ReflectionTestUtils from Spring in mockito, use

Whitebox.setInternalState(first, "second", sec);

There is a statement you can issue at the module level:

Option Compare Text

This makes all "text comparisons" case insensitive. This means the following code will show the message "this is true":

Option Compare Text

Sub testCase()
  If "UPPERcase" = "upperCASE" Then
    MsgBox "this is true: option Compare Text has been set!"
  End If
End Sub

See for example http://www.ozgrid.com/VBA/vba-case-sensitive.htm . I'm not sure it will completely solve the problem for all instances (such as the Application.Match function) but it will take care of all the if a=b statements. As for Application.Match - you may want to convert the arguments to either upper case or lower case using the LCase function.

Forget float, margin and html 3/5. The mail is very obsolete. You need do all with table. One line = one table. You need margin or padding ? Do another column.

Codepen

Example : i need one line with 1 One Picture of 40*40 2 One margin of 10 px 3 One text of 400px

I start my line :

<table style=" background-repeat:no-repeat; width:450px;margin:0;" cellpadding="0" cellspacing="0" border="0">
   <tr style="height:40px; width:450px; margin:0;">
     <td style="height:40px; width:40px; margin:0;">
        <img src="" style="width=40px;height40;margin:0;display:block"
     </td>
     <td style="height:40px; width:10px; margin:0;">        
     </td>
     <td style="height:40px; width:400px; margin:0;">
     <p style=" margin:0;"> my text   </p>
     </td>
   </tr>
</table>

This is working for me and I hope it will work for you.

Just do:

List a = new ArrayList(); 
a.add("a"); 
a.add("b"); 
a.add("c"); 
List b = new ArrayList(a);

ArrayList has a constructor that will accept another Collection to copy the elements from

What if you don't want to commit every commit that you make in Git, to the SVN repository? What if you just want to selectively send commits up the pipe? Well, I have a better solution.

I keep one local Git repository where all I ever do is fetch and merge from SVN. That way I can make sure I'm including all the same changes as SVN, but I keep my commit history separate from the SVN entirely.

Then I keep a separate SVN local working copy that is in a separate folder. That's the one I make commits back to SVN from, and I simply use the SVN command line utility for that.

When I'm ready to commit my local Git repository's state to SVN, I simply copy the whole mess of files over into the local SVN working copy and commit it from there using SVN rather than Git.

This way I never have to do any rebasing, because rebasing is like freebasing.

It has already been explained that calling system.gc() may do nothing, and that any code that "needs" the garbage collector to run is broken.

However, the pragmatic reason that it is bad practice to call System.gc() is that it is inefficient. And in the worst case, it is horribly inefficient! Let me explain.

A typical GC algorithm identifies garbage by traversing all non-garbage objects in the heap, and inferring that any object not visited must be garbage. From this, we can model the total work of a garbage collection consists of one part that is proportional to the amount of live data, and another part that is proportional to the amount of garbage; i.e. work = (live * W1 + garbage * W2).

Now suppose that you do the following in a single-threaded application.

System.gc(); System.gc();

The first call will (we predict) do (live * W1 + garbage * W2) work, and get rid of the outstanding garbage.

The second call will do (live* W1 + 0 * W2) work and reclaim nothing. In other words we have done (live * W1) work and achieved absolutely nothing.

We can model the efficiency of the collector as the amount of work needed to collect a unit of garbage; i.e. efficiency = (live * W1 + garbage * W2) / garbage. So to make the GC as efficient as possible, we need to maximize the value of garbage when we run the GC; i.e. wait until the heap is full. (And also, make the heap as big as possible. But that is a separate topic.)

If the application does not interfere (by calling System.gc()), the GC will wait until the heap is full before running, resulting in efficient collection of garbage¹. But if the application forces the GC to run, the chances are that the heap won't be full, and the result will be that garbage is collected inefficiently. And the more often the application forces GC, the more inefficient the GC becomes.

Note: the above explanation glosses over the fact that a typical modern GC partitions the heap into "spaces", the GC may dynamically expand the heap, the application's working set of non-garbage objects may vary and so on. Even so, the same basic principal applies across the board to all true garbage collectors². It is inefficient to force the GC to run.

^{1 - This is how the "throughput" collector works. Concurrent collectors such as CMS and G1 use different criteria to decide when to start the garbage collector.}

^{2 - I'm also excluding memory managers that use reference counting exclusively, but no current Java implementation uses that approach ... for good reason.}

My guess at a "bulletproof way to do this" (think CIA finding Waldo in any satellite image any time, not just a single image without competing elements, like striped shirts)... I would train a Boltzmann machine on many images of Waldo - all variations of him sitting, standing, occluded, etc.; shirt, hat, camera, and all the works. You don't need a large corpus of Waldos (maybe 3-5 will be enough), but the more the better.

This will assign clouds of probabilities to various elements occurring in whatever the correct arrangement, and then establish (via segmentation) what an average object size is, fragment the source image into cells of objects which most resemble individual people (considering possible occlusions and pose changes), but since Waldo pictures usually include a LOT of people at about the same scale, this should be a very easy task, then feed these segments of the pre-trained Boltzmann machine. It will give you probability of each one being Waldo. Take one with the highest probability.

This is how OCR, ZIP code readers, and strokeless handwriting recognition work today. Basically you know the answer is there, you know more or less what it should look like, and everything else may have common elements, but is definitely "not it", so you don't bother with the "not it"s, you just look of the likelihood of "it" among all possible "it"s you've seen before" (in ZIP codes for example, you'd train BM for just 1s, just 2s, just 3s, etc., then feed each digit to each machine, and pick one that has most confidence). This works a lot better than a single neural network learning features of all numbers.

Well, first off an associative array can only have a key defined once, so this array would never exist. Otherwise, just use in_array() to determine if that specific array element is in an array of possible solutions.

I used this for a comment section:

You could float the child-right to the right, but in this case I've calculated the widths of each div precisely.

Another way to remove VBA project password is;

• Open xls file with a hex editor. (ie. Hex Edit http://www.hexedit.com/)
• Search for DPB
• Replace DPB to DPx
• Save file.
• Open file in Excel.
• Click "Yes" if you get any message box.
• Set new password from VBA Project Properties.
• Close and open again file, then type your new password to unprotect.

UPDATE: For Excel 2010 (Works for MS Office Pro Plus 2010 [14.0.6023.1000 64bit]),

• Open the XLSX file with 7zip

If workbook is protected:

• Browse the folder xl
• If the workbook is protected, right click workbook.xml and select Edit
• Find the portion <workbookProtection workbookPassword="XXXX" lockStructure="1"/> (XXXX is your encrypted password)
• Remove XXXX part. (ie. <workbookProtection workbookPassword="" lockStructure="1"/>)
• Save the file.
• When 7zip asks you to update the archive, say Yes.
• Close 7zip and re-open your XLSX.
• Click Protect Workbook on Review tab.
• Optional: Save your file.

If worksheets are protected:

• Browse to xl/worksheets/ folder.
• Right click the Sheet1.xml, sheet2.xml, etc and select Edit.
• Find the portion <sheetProtection password="XXXX" sheet="1" objects="1" scenarios="1" />
• Remove the encrypted password (ie. <sheetProtection password="" sheet="1" objects="1" scenarios="1" />)
• Save the file.
• When 7zip asks you to update the archive, say Yes.
• Close 7zip and re-open your XLSX.
• Click Unprotect Sheet on Review tab.
• Optional: Save your file.

This is happening because there is a field in .env file named, APP_KEY, which is blank now, we need some random key for this variable.

Follow these steps to get rid of this problem.

1) .env.example to .env

2) Go to your root directory in your command prompt (If you are using windows)/terminal (If you are using MAC or LINUX) where you have installed laravel project/files and run following command

php artisan key:generate

and then run your project. It's all done.

Here is my solution: https://github.com/sasha-ch/Aura.Sql based on auraphp/Aura.Sql library.

Usage example:

$q = "insert into t2(id,name) values (?,?), ... on duplicate key update name=name"; 
$bind_values = [ [[1,'str1'],[2,'str2']] ];
$pdo->perform($q, $bind_values);

I have had the same problem in the past on many sites I have done here at work. The only guaranteed method of making sure the user gets the email is to advise the user to add you to there safe list. Any other method is really only going to be something that can help with it and isn't guaranteed.

1st way is to use props

<Row id = "someRandomID">

Wherein, in the Definition, you may just go

const Row = props  => {
 div id = {props.id}
}

The same could be done with class, replacing id with className in the above example.

You might as well use react-html-id, that is an npm package. This is an npm package that allows you to use unique html IDs for components without any dependencies on other libraries.

Peace.

This answer will do what you need, although usually you don't add specific usernames to sudoers. Instead, you have a group of sudoers and just add your user to that group when needed. This way you don't need to use visudo more than once when giving sudo permission to users.

If you're on Ubuntu, the group is most probably already set up and called admin:

$ sudo cat /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#

...

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

# Allow members of group sudo to execute any command
%sudo   ALL=(ALL:ALL) ALL

# See sudoers(5) for more information on "#include" directives:

#includedir /etc/sudoers.d

On other distributions, like Arch and some others, it's usually called wheel and you may need to set it up: Arch Wiki

To give users in the wheel group full root privileges when they precede a command with "sudo", uncomment the following line: %wheel ALL=(ALL) ALL

Also note that on most systems visudo will read the EDITOR environment variable or default to using vi. So you can try to do EDITOR=vim visudo to use vim as the editor.

To add a user to the group you should run (as root):

# usermod -a -G groupname username

where groupname is your group (say, admin or wheel) and username is the username (say, john).

I have struggled mightily to get the behavior I want. This is the easiest and best way to get TypeScript files to compile on save, to the configuration I want, only THIS file (the saved file). It's a tasks.json and a keybindings.json.

This code is working for me:

JavascriptExecutor js = (JavascriptExecutor) driver;
js.executeScript("javascript:window.scrollBy(250, 350)");

test = {'foo': 'bar', 'hello': 'world'}
ls = []
for key in test.keys():
    ls.append(key)
print(ls[0])

Conventional way of appending the keys to a statically defined list and then indexing it for same

As already mentioned in the answer by robertc, Chrome blocks certain functionality, like the geo location with local files. An easier alternative to setting up an own web server would be to just start Chrome with the parameter --allow-file-access-from-files. Then you can use the geo location, provided you didn't turn it off in your settings.

You can also try this: Go to the path where Python is installed in your system. For me it was something like C:\Users\\Local Settings\Application Data\Programs\Python\Python37 In this folder, you'll find a python executable. Just create a duplicate and rename it to python3. Works every time.

Perhaps surprisingly you can logoff users with the logoff command.

C:\> logoff /?
Terminates a session.

LOGOFF [sessionname | sessionid] [/SERVER:servername] [/V] [/VM]

  sessionname         The name of the session.
  sessionid           The ID of the session.
  /SERVER:servername  Specifies the Remote Desktop server containing the user
                      session to log off (default is current).
  /V                  Displays information about the actions performed.
  /VM                 Logs off a session on server or within virtual machine.
                      The unique ID of the session needs to be specified.

The session ID can be determined with the qwinsta (query session) or quser (query user) commands (see here):

$server   = 'MyServer'
$username = $env:USERNAME

$session = ((quser /server:$server | ? { $_ -match $username }) -split ' +')[2]

logoff $session /server:$server

Do it like this:

char s[256];
strcpy(s, "one two three");
char* token = strtok(s, " ");
while (token) {
    printf("token: %s\n", token);
    token = strtok(NULL, " ");
}

Note: strtok modifies the string its tokenising, so it cannot be a const char*.

I think one of the Advantages of code first is that you can back up all the changes you've made to a version control system like Git. Because all your tables and relationships are stored in what are essentially just classes, you can go back in time and see what the structure of your database was before.

You can use Configuration to resolve this.

Ex (Startup.cs):

You can pass by DI to the controllers after this implementation.

public class Startup
{
    public Startup(IHostingEnvironment env)
    {
        var builder = new ConfigurationBuilder()
        .SetBasePath(env.ContentRootPath)
        .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);

        Configuration = builder.Build();

    }

    public IConfiguration Configuration { get; }

    // This method gets called by the runtime. Use this method to add services to the container.
    public void ConfigureServices(IServiceCollection services)
    {

        var microserviceName = Configuration["microserviceName"];

       services.AddSingleton(Configuration);

       ...
    }

Note: please update the date format accordingly.

Format Date

   __formatDate: function(myDate){
      var ts = moment.utc(myDate);
      return ts.local().format('D-MMM-Y');
   }

Format Time

  __formatTime: function(myDate){
      var ts = moment.utc(myDate);
      return ts.local().format('HH:mm');
  },

Another solution is to use stat_count() when dealing with discrete variables (and stat_bin() with continuous ones).

ggplot(data = df, aes(x = x)) +
geom_bar(stat = "count") + 
stat_count(geom = "text", colour = "white", size = 3.5,
aes(label = ..count..),position=position_stack(vjust=0.5))

Import in Java does not work at all, as it is evaluated at compile time only. (Treat it as shortcuts so you do not have to write fully qualified class names). At runtime there is no import at all, just FQCNs.

At runtime it is necessary that all classes you have referenced can be found by classloaders. (classloader infrastructure is sometimes dark magic and highly dependent on environment.) In case of an applet you will have to rig up your HTML tag properly and also provide necessary JAR archives on your server.

PS: Matching at runtime is done via qualified class names - class found under this name is not necessarily the same or compatible with class you have compiled against.

I have been having the same issue and tried everything written here but it was still giving me the same error. Turned out to be NULL value in the column which I was trying to convert.

Removing the NULL value solved my issue.

You can assign the class name like text-center, left or right. The text will align accordingly to these class name. You don't need to make extra class name separately. These classes are built in BootStrap 3 and bootstrap 4.

As far as i know that is impossible and that makes sense since what you are trying to do is against the idea of tabular data presentation. You could however put the data in multiple tables and remove any padding and margins in between them to achieve the same result, at least visibly. Something along the lines of:

<html>_x000D_
_x000D_
<head>_x000D_
  <style type="text/css">_x000D_
    .mytable {_x000D_
      border-collapse: collapse;_x000D_
      width: 100%;_x000D_
      background-color: white;_x000D_
    }_x000D_
    .mytable-head {_x000D_
      border: 1px solid black;_x000D_
      margin-bottom: 0;_x000D_
      padding-bottom: 0;_x000D_

JSFIDDLE

I don't know your requirements but i'm sure there's a more elegant solution.

int numberOfSpaces = 3;
String space = String.format("%"+ numberOfSpaces +"s", " ");

If you want to remove more characters for example "a", "A", "b", "B", "c", "C" from string you can do it this way:

someString = someString.replacingOccurrences(of: "[abc]", with: "", options: [.regularExpression, .caseInsensitive])

Ok, I don't normally answer my own questions but after a bit of tinkering, I have figured out definitively how Oracle stores the result of a DATE subtraction.

When you subtract 2 dates, the value is not a NUMBER datatype (as the Oracle 11.2 SQL Reference manual would have you believe). The internal datatype number of a DATE subtraction is 14, which is a non-documented internal datatype (NUMBER is internal datatype number 2). However, it is actually stored as 2 separate two's complement signed numbers, with the first 4 bytes used to represent the number of days and the last 4 bytes used to represent the number of seconds.

An example of a DATE subtraction resulting in a positive integer difference:

select date '2009-08-07' - date '2008-08-08' from dual;

Results in:

DATE'2009-08-07'-DATE'2008-08-08'
---------------------------------
                              364

select dump(date '2009-08-07' - date '2008-08-08') from dual;

DUMP(DATE'2009-08-07'-DATE'2008
-------------------------------
Typ=14 Len=8: 108,1,0,0,0,0,0,0

Recall that the result is represented as a 2 seperate two's complement signed 4 byte numbers. Since there are no decimals in this case (364 days and 0 hours exactly), the last 4 bytes are all 0s and can be ignored. For the first 4 bytes, because my CPU has a little-endian architecture, the bytes are reversed and should be read as 1,108 or 0x16c, which is decimal 364.

An example of a DATE subtraction resulting in a negative integer difference:

select date '1000-08-07' - date '2008-08-08' from dual;

Results in:

DATE'1000-08-07'-DATE'2008-08-08'
---------------------------------
                          -368160

select dump(date '1000-08-07' - date '2008-08-08') from dual;

DUMP(DATE'1000-08-07'-DATE'2008-08-0
------------------------------------
Typ=14 Len=8: 224,97,250,255,0,0,0,0

Again, since I am using a little-endian machine, the bytes are reversed and should be read as 255,250,97,224 which corresponds to 11111111 11111010 01100001 11011111. Now since this is in two's complement signed binary numeral encoding, we know that the number is negative because the leftmost binary digit is a 1. To convert this into a decimal number we would have to reverse the 2's complement (subtract 1 then do the one's complement) resulting in: 00000000 00000101 10011110 00100000 which equals -368160 as suspected.

An example of a DATE subtraction resulting in a decimal difference:

select to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS'
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS') from dual;

TO_DATE('08/AUG/200414:00:00','DD/MON/YYYYHH24:MI:SS')-TO_DATE('08/AUG/20048:00:
--------------------------------------------------------------------------------
                                                                             .25

The difference between those 2 dates is 0.25 days or 6 hours.

select dump(to_date('08/AUG/2004 14:00:00', 'DD/MON/YYYY HH24:MI:SS')
 - to_date('08/AUG/2004 8:00:00', 'DD/MON/YYYY HH24:MI:SS')) from dual;

DUMP(TO_DATE('08/AUG/200414:00:
-------------------------------
Typ=14 Len=8: 0,0,0,0,96,84,0,0

Now this time, since the difference is 0 days and 6 hours, it is expected that the first 4 bytes are 0. For the last 4 bytes, we can reverse them (because CPU is little-endian) and get 84,96 = 01010100 01100000 base 2 = 21600 in decimal. Converting 21600 seconds to hours gives you 6 hours which is the difference which we expected.

Hope this helps anyone who was wondering how a DATE subtraction is actually stored.

You get the syntax error because the date math does not return a NUMBER, but it returns an INTERVAL:

SQL> SELECT DUMP(SYSDATE - start_date) from test;

DUMP(SYSDATE-START_DATE)
-------------------------------------- 
Typ=14 Len=8: 188,10,0,0,223,65,1,0

You need to convert the number in your example into an INTERVAL first using the NUMTODSINTERVAL Function

For example:

SQL> SELECT (SYSDATE - start_date) DAY(5) TO SECOND from test;

(SYSDATE-START_DATE)DAY(5)TOSECOND
----------------------------------
+02748 22:50:04.000000

SQL> SELECT (SYSDATE - start_date) from test;

(SYSDATE-START_DATE)
--------------------
           2748.9515

SQL> select NUMTODSINTERVAL(2748.9515, 'day') from dual;

NUMTODSINTERVAL(2748.9515,'DAY')
--------------------------------
+000002748 22:50:09.600000000

SQL>

Based on the reverse cast with the NUMTODSINTERVAL() function, it appears some rounding is lost in translation.

C doesn't have exceptions.

There are various hacky implementations that try to do it (one example at: http://adomas.org/excc/).

#some example data
set.seed(42)
df <- data.frame(x = rep(1:10,each=5), y = rnorm(50))

#calculate mean, min and max for each x-value
library(plyr)
df2 <- ddply(df,.(x),function(df) c(mean=mean(df$y),min=min(df$y),max=max(df$y)))

#plot error bars
library(Hmisc)
with(df2,errbar(x,mean,max,min))
grid(nx=NA,ny=NULL)

Your method's return type is int and you're trying to return an int?.

h.inject({}) { |m, (k,v)| m[k.sub(/^_/,'')] = v; m }

Used the above code in MVC5 project and it works completely fine with the validation error. Just try this code:

   [Required]
   [Display(Name = "Email")]
   [EmailAddress]

   [RegularExpression(@"^([A-Za-z0-9][^'!&\\#*$%^?<>()+=:;`~\[\]{}|/,?€@ ][a-zA-z0- 
    9-._][^!&\\#*$%^?<>()+=:;`~\[\]{}|/,?€@ ]*\@[a-zA-Z0-9][^!&@\\#*$%^?<> 
        ()+=':;~`.\[\]{}|/,?€ ]*\.[a-zA-Z]{2,6})$", ErrorMessage = "Please enter a 
   valid Email")]


   public string ReceiverMail { get; set; }

Here's my code to find controls by Type while controlling how deep we go into the hierarchy (maxDepth == 0 means infinitely deep).

public static class FrameworkElementExtension
{
    public static object[] FindControls(
        this FrameworkElement f, Type childType, int maxDepth)
    {
        return RecursiveFindControls(f, childType, 1, maxDepth);
    }

    private static object[] RecursiveFindControls(
        object o, Type childType, int depth, int maxDepth = 0)
    {
        List<object> list = new List<object>();
        var attrs = o.GetType()
            .GetCustomAttributes(typeof(ContentPropertyAttribute), true);
        if (attrs != null && attrs.Length > 0)
        {
            string childrenProperty = (attrs[0] as ContentPropertyAttribute).Name;
            foreach (var c in (IEnumerable)o.GetType()
                .GetProperty(childrenProperty).GetValue(o, null))
            {
                if (c.GetType().FullName == childType.FullName)
                    list.Add(c);
                if (maxDepth == 0 || depth < maxDepth)
                    list.AddRange(RecursiveFindControls(
                        c, childType, depth + 1, maxDepth));
            }
        }
        return list.ToArray();
    }
}

Parameters are key-value pairs that can appear inside URL path, and start with a semicolon character (;).

Query string appears after the path (if any) and starts with a question mark character (?).

Both parameters and query string contain key-value pairs.

In a GET request, parameters appear in the URL itself:

<scheme>://<username>:<password>@<host>:<port>/<path>;<parameters>?<query>#<fragment>

In a POST request, parameters can appear in the URL itself, but also in the datastream (as known as content).

Query string is always a part of the URL.

Parameters can be buried in form-data datastream when using POST method so they may not appear in the URL. Yes a POST request can define parameters as form data and in the URL, and this is not inconsistent because parameters can have several values.

I've found no explaination for this behavior so far. I guess it might be useful sometimes to "unhide" parameters from a POST request, or even let the code handling a GET request share some parts with the code handling a POST. Of course this can work only with server code supporting parameters in a URL.

Until you get better insights, I suggest you to use parameters only in form-data datastream of POST requests.

What Every Developer Should Know About URLs

RFC 3986

From the comments to activestate recipe 498181 I reworked this:

import re
def thous(x, sep=',', dot='.'):
    num, _, frac = str(x).partition(dot)
    num = re.sub(r'(\d{3})(?=\d)', r'\1'+sep, num[::-1])[::-1]
    if frac:
        num += dot + frac
    return num

It uses the regular expressions feature: lookahead i.e. (?=\d) to make sure only groups of three digits that have a digit 'after' them get a comma. I say 'after' because the string is reverse at this point.

[::-1] just reverses a string.

Pojo also consider as Model class in Java where we can create getter and setter for particular variable defined in private . Remember all variables are here declared with private modifier

                function formatThousands(n,dp,f) {
                    // dp - decimal places
                    // f - format >> 'us', 'eu'
                    if (n == 0) {
                        if(f == 'eu') {
                            return "0," + "0".repeat(dp);   
                        }
                        return "0." + "0".repeat(dp);
                    }

                    /* round to 2 decimal places */
                    //n = Math.round( n * 100 ) / 100;
                    var s = ''+(Math.floor(n)), d = n % 1, i = s.length, r = '';
                    while ( (i -= 3) > 0 ) { r = ',' + s.substr(i, 3) + r; }
                    var a = s.substr(0, i + 3) + r + (d ? '.' + Math.round((d+1) * Math.pow(10,dp)).toString().substr(1,dp) : '');
                    /* change format from 20,000.00 to 20.000,00 */
                    if (f == 'eu') {
                        var b = a.toString().replace(".", "#");
                        b = b.replace(",", ".");
                        return b.replace("#", ",");
                    }                   
                    return a;
                }

@ts-expect-error

TS 3.9 introduces a new magic comment. @ts-expect-error will:

• have same functionality as @ts-ignore
• trigger an error, if actually no compiler error has been suppressed (= indicates useless flag)

if (false) {
  // @ts-expect-error: Let's ignore a single compiler error like this unreachable code 
  console.log("hello"); // compiles
}

// If @ts-expect-error didn't suppress anything at all, we now get a nice warning 
let flag = true;
// ...
if (flag) {
  // @ts-expect-error
  // ^~~~~~~~~~~~~~~^ error: "Unused '@ts-expect-error' directive.(2578)"
  console.log("hello"); 
}

Alternatives

@ts-ignore and @ts-expect-error can be used for all sorts of compiler errors. For type issues (like in OP), I recommend one of the following alternatives due to narrower error suppression scope:

? Use any type

// type assertion for single expression
delete ($ as any).summernote.options.keyMap.pc.TAB;

// new variable assignment for multiple usages
const $$: any = $
delete $$.summernote.options.keyMap.pc.TAB;
delete $$.summernote.options.keyMap.mac.TAB;

? Augment JQueryStatic interface

// ./global.d.ts
interface JQueryStatic {
  summernote: any;
}

// ./main.ts
delete $.summernote.options.keyMap.pc.TAB; // works

In other cases, shorthand module declarations or module augmentations for modules with no/extendable types are handy utilities. A viable strategy is also to keep not migrated code in .js and use --allowJs with checkJs: false.

If you need to make single element you can use this construction:

$('<option/>', {
    'class': this.dataID,
    'text': this.s_dataValue
}).appendTo('.subCategory');

But if you need to print many elements you can use this construction:

function printOptions(arr){
    jQuery.each(arr, function(){
        $('<option/>', {
            'value': this.dataID,
            'text': this.s_dataValue
        }).appendTo('.subCategory');
    });
}

In C++ it is done like this:

#define LOCAL_PI 3.1415926535897932385 

double ToRadians(double degrees) 
{
  double radians = degrees * LOCAL_PI / 180;
  return radians;
}

double DirectDistance(double lat1, double lng1, double lat2, double lng2) 
{
  double earthRadius = 3958.75;
  double dLat = ToRadians(lat2-lat1);
  double dLng = ToRadians(lng2-lng1);
  double a = sin(dLat/2) * sin(dLat/2) + 
             cos(ToRadians(lat1)) * cos(ToRadians(lat2)) * 
             sin(dLng/2) * sin(dLng/2);
  double c = 2 * atan2(sqrt(a), sqrt(1-a));
  double dist = earthRadius * c;
  double meterConversion = 1609.00;
  return dist * meterConversion;
}

this is my working batch

You should know the PID of your process.

When you launch it, its PID will be recorded in the $! variable. Save this PID into a file.

Then you will need to check if this PID corresponds to a running process. Here's a complete skeleton script:

FILE="/tmp/myapp.pid"

if [ -f $FILE ];
then
   PID=$(cat $FILE)
else
   PID=1
fi

ps -o pid= -p $PID
if [ $? -eq 0 ]; then
  echo "Process already running."  
else
  echo "Starting process."
  run_my_app &
  echo $! > $FILE
fi

Based on the answer of peterh. The trick for knowing if a given PID is running is in the ps -o pid= -p $PID instruction.

Solution as ReactJS Component

Bytes = React.createClass({
    formatBytes() {
        var i = Math.floor(Math.log(this.props.bytes) / Math.log(1024));
        return !this.props.bytes && '0 Bytes' || (this.props.bytes / Math.pow(1024, i)).toFixed(2) + " " + ['Bytes', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'][i]
    },
    render () {
        return (
            <span>{ this.formatBytes() }</span>
        );
    }
});

UPDATE For those using es6 here is a stateless version of this same component

const sufixes = ['Bytes', 'KB', 'MB', 'GB', 'TB', 'PB', 'EB', 'ZB', 'YB'];
const getBytes = (bytes) => {
  const i = Math.floor(Math.log(bytes) / Math.log(1024));
  return !bytes && '0 Bytes' || (bytes / Math.pow(1024, i)).toFixed(2) + " " + sufixes[i];
};

const Bytes = ({ bytes }) => (<span>{ getBytes(bytes) }</span>);

Bytes.propTypes = {
  bytes: React.PropTypes.number,
};

If you are using spring with application.yml the following will work for you

spring: datasource: url: jdbc:h2:mem:mydb;DB_CLOSE_ON_EXIT=FALSE;MODE=PostgreSQL;INIT=CREATE SCHEMA IF NOT EXISTS calendar

Depends on the language, but there are generally negative-assertions you can put in like so:

(?!red|green|blue)

(Thanks for the syntax fix, the above is valid Java and Perl, YMMV)

If you are out of the Loop of WordPress you can not use any of the method of wordpress so you must use pure php.

You can use this code. And sure will help you :)

$page_id = @$_GET['page_id'];

if (!is_numeric($page_id)) {
    // Then the uri must be in friendly format aka /my_domain/category/onepage/
    // Try this
    //$path = '/www/public_html/index.php/';
    ///$path = '/my_domain/category/onepage/';
    $path = $_SERVER['REQUEST_URI'];
    // Clean the uri
    //$path = str_replace('/', '', $page);
    $path = str_replace('.php', '', $path);
    //$path = str_replace('?s=', '', $path);
    $path = $path ? $path : 'default';

    $path_len = strlen($path);
    $last_char = substr($path, $path_len -1);
    //echo $last_char;
    $has_slash = strpos($last_char, "/");
    //echo $has_slash;
    if ($has_slash === 0) :
        $path = substr($path, 0, $path_len -1);
    elseif ($has_slash === null) :
        $path = substr($path, 0, $path_len);
    endif;
    //echo "path: ".$path; // '/www/public_html/index'
    $page = substr(strrchr($path, "/"), 1);
    echo "page: ".$page; // 'index'
}

$my_page_id = 31;
$my_page = 'mypage';

//echo "page: ".$page;
//echo "page_id ".$page_id;
if($page_id == $my_page_id || $page == $my_page) 
{
    // your stuff....
}

Codeproject has a complete solution for this:

http://www.codeproject.com/Articles/17241/Capturing-the-Enter-key-to-cause-a-button-click

and like the article says: "decide which solution best fits your needs"

=================== EDITED ANSWER ============================

The link mentioned above, talks about two ways of capturing the "Enter Key" event:

Javascript (bind the onKeyPress event to the object and create a javascript function to check which key was pressed and do your logic)

_Page_Load in code behind:_

 //Add the javascript so we know where we want the enter key press to go
if (!IsPostBack)
{
   txtboxFirstName.Attributes.Add("onKeyPress", 
                   "doClick('" + btnSearch.ClientID + "',event)");
   txtboxLastName.Attributes.Add("onKeyPress", 
                  "doClick('" + btnSearch.ClientID + "',event)");
}

Javascript code:

<SCRIPT type=text/javascript>
    function doClick(buttonName,e)
    {
        //the purpose of this function is to allow the enter key to 
        //point to the correct button to click.
        var key;

         if(window.event)
              key = window.event.keyCode;     //IE
         else
              key = e.which;     //firefox

        if (key == 13)
        {
            //Get the button the user wants to have clicked
            var btn = document.getElementById(buttonName);
            if (btn != null)
            { //If we find the button click it
                btn.click();

Panel Control

<asp:Panel ID="panSearch" runat="server" DefaultButton="btnSearch2" Width="100%" >
    <asp:TextBox ID="txtboxFirstName2" runat="server" ></asp:TextBox>
</asp:Panel>

Quoting:

Notice that the Panel tag has a property called DefaultButton. You set this property to the button ID of the button you want to be clicked on an Enter key press event. So any text box inside of the Panel will direct its Enter key press to the button set in the DefaultButton property of the Panel

This should work for you

//Retrieve Minimum Date
var MinDate = (from d in dataRows select d.Date).Min();

//Retrieve Maximum Date
var MaxDate = (from d in dataRows select d.Date).Max();

Based on Eyecue answer (Jun 10 '10 at 21:28): this class add head() and tail() method to file object.

class File(file):
    def head(self, lines_2find=1):
        self.seek(0)                            #Rewind file
        return [self.next() for x in xrange(lines_2find)]

    def tail(self, lines_2find=1):  
        self.seek(0, 2)                         #go to end of file
        bytes_in_file = self.tell()             
        lines_found, total_bytes_scanned = 0, 0
        while (lines_2find+1 > lines_found and
               bytes_in_file > total_bytes_scanned): 
            byte_block = min(1024, bytes_in_file-total_bytes_scanned)
            self.seek(-(byte_block+total_bytes_scanned), 2)
            total_bytes_scanned += byte_block
            lines_found += self.read(1024).count('\n')
        self.seek(-total_bytes_scanned, 2)
        line_list = list(self.readlines())
        return line_list[-lines_2find:]

Usage:

f = File('path/to/file', 'r')
f.head(3)
f.tail(3)

var monthIndex = 1;
return month = DateTimeFormatInfo.CurrentInfo.GetAbbreviatedMonthName(monthIndex);

You can try this one as well

There is a difference between initialization and assignment. What you want to do is not initialization, but assignment. But such assignment to array is not possible in C++.

Here is what you can do:

#include <algorithm>

int array [] = {1,3,34,5,6};
int newarr [] = {34,2,4,5,6};
std::copy(newarr, newarr + 5, array);

However, in C++0x, you can do this:

std::vector<int> array = {1,3,34,5,6};
array = {34,2,4,5,6};

Of course, if you choose to use std::vector instead of raw array.

As you'll be using jQuery anyway, try:

https://github.com/cowboy/jquery-replacetext

Then just do

$("p").replaceText("£", "$")

It seems to do good job of only replacing text and not messing with other elements

Have you tried to use Tomcat's Manager application? It allows you to undeploy / deploy war files with out shutting Tomcat down.

If you don't want to use the Manager application, you can also delete the war file from the webapps directory, Tomcat will undeploy the application after a short period of time. You can then copy a war file back into the directory, and Tomcat will deploy the war file.

If you are running Tomcat on Windows, you may need to configure your Context to not lock various files.

If you absolutely can't have any downtime, you may want to look at Tomcat 7's Parallel deployments You may deploy multiple versions of a web application with the same context path at the same time. The rules used to match requests to a context version are as follows:

• If no session information is present in the request, use the latest version.
• If session information is present in the request, check the session manager of each version for a matching session and if one is found, use that version.
• If session information is present in the request but no matching session can be found, use the latest version.

var array = a.split(' '); 
array.splice(position, 0, b);
var output = array.join(' ');

This would be slower, but will take care of the addition of space before and after the an Also, you'll have to change the value of position ( to 2, it's more intuitive now)

Faster way is below. Considering letters are only a-z,A-Z.

public static void main( String[] args ){ 
        System.out.println(bestWay("azAZpratiyushkumarsinghjdnfkjsaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"));
        System.out.println(isAlpha("azAZpratiyushkumarsinghjdnfkjsaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"));

        System.out.println(bestWay("azAZpratiyushkumarsinghjdnfkjsaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa1aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"));
        System.out.println(isAlpha("azAZpratiyushkumarsinghjdnfkjsaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa1aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"));
    }

    public static boolean bettertWay(String name) {
        char[] chars = name.toCharArray();
        long startTimeOne = System.nanoTime();
        for(char c : chars){
            if(!(c>=65 && c<=90)&&!(c>=97 && c<=122) ){
                System.out.println(System.nanoTime() - startTimeOne);
                    return false;
            }
        }
        System.out.println(System.nanoTime() - startTimeOne);
        return true;
    }


    public static boolean isAlpha(String name) {
        char[] chars = name.toCharArray();
        long startTimeOne = System.nanoTime();
        for (char c : chars) {
            if(!Character.isLetter(c)) {
                System.out.println(System.nanoTime() - startTimeOne);
                return false;
            }
        }
        System.out.println(System.nanoTime() - startTimeOne);
        return true;
    }

Runtime is calculated in nano seconds. It may vary system to system.

I think request.domain would work, but what if you're in a sub directory like blah.blah.com? Something like this could work:

<%= request.env["HTTP_HOST"] + page = "/" + request.path_parameters['controller'] + "/" + request.path_parameters['action'] %>

Change the parameters based on your path structure.

Hope that helps!

create shake.xml in anim folder

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android" 
    android:fromXDelta="0" 
        android:toXDelta="10" 
            android:duration="1000" 
                android:interpolator="@anim/cycle" />

and cycle.xml in anim folder

<?xml version="1.0" encoding="utf-8"?>
<cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android" 
    android:cycles="4" />

now add animation on your code

Animation shake = AnimationUtils.loadAnimation(this, R.anim.shake);
anyview.startAnimation(shake);

If you want vertical animation, change fromXdelta and toXdelta value to fromYdelta and toYdelta value

In HTML there's an autofocus attribute to all form fields. There's a good tutorial on it in Dive Into HTML 5. Unfortunately it's currently not supported by IE versions less than 10.

To use the HTML 5 attribute and fall back to a JS option:

<input id="my-input" autofocus="autofocus" />
<script>
  if (!("autofocus" in document.createElement("input"))) {
    document.getElementById("my-input").focus();
  }
</script>

No jQuery, onload or event handlers are required, because the JS is below the HTML element.

Edit: another advantage is that it works with JavaScript off in some browsers and you can remove the JavaScript when you don't want to support older browsers.

Edit 2: Firefox 4 now supports the autofocus attribute, just leaving IE without support.

Using a function converting an hexa string to byte[], you could do

byte[] CDRIVES = hexStringToByteArray("e04fd020ea3a6910a2d808002b30309d");

I'd suggest you use the function defined by Dave L in Convert a string representation of a hex dump to a byte array using Java?

I insert it here for maximum readability :

public static byte[] hexStringToByteArray(String s) {
    int len = s.length();
    byte[] data = new byte[len / 2];
    for (int i = 0; i < len; i += 2) {
        data[i / 2] = (byte) ((Character.digit(s.charAt(i), 16) << 4)
                             + Character.digit(s.charAt(i+1), 16));
    }
    return data;
}

If you let CDRIVES static and final, the performance drop is irrelevant.

COUNTER BEING A PRIMITIVE

Let's define callback functions as follows:

// ****************************
// COUNTER BEING A PRIMITIVE
// ****************************
function test1() {
    for (var i=0; i<2; i++) {
        setTimeout(function() {
            console.log(i);
        });
    }
}
test1();
// 2
// 2

After timeout completes it will print 2 for both. This is because the callback function accesses the value based on the lexical scope, where it was function was defined.

To pass and preserve the value while callback was defined, we can create a closure, to preserve the value before the callback is invoked. This can be done as follows:

function test2() {
    function sendRequest(i) {
        setTimeout(function() {
            console.log(i);
        });
    }

    for (var i = 0; i < 2; i++) {
        sendRequest(i);
    }
}
test2();
// 1
// 2

Now what's special about this is "The primitives are passed by value and copied. Thus when the closure is defined, they keep the value from the previous loop."

COUNTER BEING AN OBJECT

Since closures have access to parent function variables via reference, this approach would differ from that for primitives.

// ****************************
// COUNTER BEING AN OBJECT
// ****************************
function test3() {
    var index = { i: 0 };
    for (index.i=0; index.i<2; index.i++) {
        setTimeout(function() {
            console.log('test3: ' + index.i);
        });
    }
}
test3();
// 2
// 2

So, even if a closure is created for the variable being passed as an object, the value of the loop index will not be preserved. This is to show that the values of an object are not copied whereas they are accessed via reference.

function test4() {
    var index = { i: 0 };
    function sendRequest(index, i) {
        setTimeout(function() {
            console.log('index: ' + index);
            console.log('i: ' + i);
            console.log(index[i]);
        });
    }

    for (index.i=0; index.i<2; index.i++) {
        sendRequest(index, index.i);
    }
}
test4();
// index: { i: 2}
// 0
// undefined

// index: { i: 2}
// 1
// undefined

The key bindings has been changed with version 1.20:

SHIFT+ALT+0 for Linux.

Presumably the same works for Windows also and CMD+OPT+0 for Mac.

I had installed Python via Anaconda.

By starting Visual Studio Code via Anaconda I was able to run Python programs.

However, I couldn't find any shortcut way (hotkey) to directly run .py files.

(Using the latest version as of Feb 21st 2019 with the Python extension which came with Visual Studio Code. Link: Python extension for Visual Studio Code)

The following worked:

1. Right clicking and selecting 'Run Python File in Terminal' worked for me.
2. Ctrl + A then Shift + Enter (on Windows)

The below is similar to what @jdhao did.

This is what I did to get the hotkey:

1. Ctrl + Shift + B // Run build task
2. It gives an option to configure
3. I clicked on it to get more options. I clicked on Other config
4. A 'tasks.json' file opened

I made the code look like this:

    {
        // See https://go.microsoft.com/fwlink/?LinkId=733558
        // for the documentation about the tasks.json format
        "version": "2.0.0",
        "tasks": [
            {
                "label": "Run Python File", //this is the label I gave
                "type": "shell",
                "command": "python",
                "args": ["${file}"]

After saving it, the file changed to this:

    {
        // See https://go.microsoft.com/fwlink/?LinkId=733558
        // for the documentation about the tasks.json format
        "version": "2.0.0",
        "tasks": [
            {
                "label": "Run Python File",
                "type": "shell",
                "command": "python",
                "args": [
                    "${file}"
                ],
                "group": {
                    "kind": "build",
                    "isDefault": true
                }
            }
        ]
    }

5. After saving the file 'tasks.json', go to your Python code and press Ctrl + Shift + B.
6. Then click on Run task ? Run Python File // This is the label that you gave.

Now every time that you press Ctrl + Shift + B, the Python file will automatically run and show you the output :)

Like

par(bg = 'blue')
# Now do plot

Regarding your query of

So when should interface with default methods be used and when should an abstract class be used? Are the abstract classes still useful in that scenario?

java documentation provides perfect answer.

Abstract Classes Compared to Interfaces:

Abstract classes are similar to interfaces. You cannot instantiate them, and they may contain a mix of methods declared with or without an implementation.

However, with abstract classes, you can declare fields that are not static and final, and define public, protected, and private concrete methods.

With interfaces, all fields are automatically public, static, and final, and all methods that you declare or define (as default methods) are public. In addition, you can extend only one class, whether or not it is abstract, whereas you can implement any number of interfaces.

Use cases for each of them have been explained in below SE post:

What is the difference between an interface and abstract class?

Are the abstract classes still useful in that scenario?

Yes. They are still useful. They can contain non-static, non-final methods and attributes (protected, private in addition to public), which is not possible even with Java-8 interfaces.

Since this question is quite old, but still comes up in google searches, I thought it would be good to point out the newer (and recommended) way to save Keras models. Instead of saving them using the older h5 format like has been shown before, it is now advised to use the SavedModel format, which is actually a dictionary that contains both the model configuration and the weights.

More information can be found here: https://www.tensorflow.org/guide/keras/save_and_serialize

The snippets to save & load can be found below:

model.fit(test_input, test_target)
# Calling save('my_model') creates a SavedModel folder 'my_model'.
model.save('my_model')

# It can be used to reconstruct the model identically.
reconstructed_model = keras.models.load_model('my_model')

A sample output of this :

git checkout -b <branch-name> <origin/branch_name>

for example in my case:

 git branch -a
* master
  origin/HEAD
  origin/enum-account-number
  origin/master
  origin/rel_table_play
  origin/sugarfield_customer_number_show_c

So to create a new branch based on my enum-account-number branch I do:

git checkout -b enum-account-number origin/enum-account-number

After you hit return the following happens:

Branch enum-account-number set up to track remote branch refs/remotes/origin/enum-account-number.
Switched to a new branch "enum-account-number"

Copy Database Dump File at (Windows PC) D:\xampp\mysql\bin

mysql -h localhost -u root Databasename <@data11.sql

If you are doing this in more than one place in your application it would make sense to use a client-side JSON database because creating custom search functions that get called by array.filter() is messy and less maintainable than the alternative.

Check out ForerunnerDB which provides you with a very powerful client-side JSON database system and includes a very simple query language to help you do exactly what you are looking for:

// Create a new instance of ForerunnerDB and then ask for a database
var fdb = new ForerunnerDB(),
    db = fdb.db('myTestDatabase'),
    coll;

// Create our new collection (like a MySQL table) and change the default
// primary key from "_id" to "id"
coll = db.collection('myCollection', {primaryKey: 'id'});

// Insert our records into the collection
coll.insert([
    {"name":"my Name","id":12,"type":"car owner"},
    {"name":"my Name2","id":13,"type":"car owner2"},
    {"name":"my Name4","id":14,"type":"car owner3"},
    {"name":"my Name4","id":15,"type":"car owner5"}
]);

// Search the collection for the string "my nam" as a case insensitive
// regular expression - this search will match all records because every
// name field has the text "my Nam" in it
var searchResultArray = coll.find({
    name: /my nam/i
});

console.log(searchResultArray);

/* Outputs
[
    {"name":"my Name","id":12,"type":"car owner"},
    {"name":"my Name2","id":13,"type":"car owner2"},
    {"name":"my Name4","id":14,"type":"car owner3"},
    {"name":"my Name4","id":15,"type":"car owner5"}
]
*/

Starting with Python 2.6 you can use anything implementing the TextIOBase API from the io module as a replacement. This solution also enables you to use sys.stdout.buffer.write() in Python 3 to write (already) encoded byte strings to stdout (see stdout in Python 3). Using StringIO wouldn't work then, because neither sys.stdout.encoding nor sys.stdout.buffer would be available.

A solution using TextIOWrapper:

import sys
from io import TextIOWrapper, BytesIO

# setup the environment
old_stdout = sys.stdout
sys.stdout = TextIOWrapper(BytesIO(), sys.stdout.encoding)

# do something that writes to stdout or stdout.buffer

# get output
sys.stdout.seek(0)      # jump to the start
out = sys.stdout.read() # read output

# restore stdout
sys.stdout.close()
sys.stdout = old_stdout

This solution works for Python 2 >= 2.6 and Python 3.

Please note that our new sys.stdout.write() only accepts unicode strings and sys.stdout.buffer.write() only accepts byte strings. This might not be the case for old code, but is often the case for code that is built to run on Python 2 and 3 without changes, which again often makes use of sys.stdout.buffer.

You can build a slight variation that accepts unicode and byte strings for write():

class StdoutBuffer(TextIOWrapper):
    def write(self, string):
        try:
            return super(StdoutBuffer, self).write(string)
        except TypeError:
            # redirect encoded byte strings directly to buffer
            return super(StdoutBuffer, self).buffer.write(string)

You don't have to set the encoding of the buffer the sys.stdout.encoding, but this helps when using this method for testing/comparing script output.

This problem happens because you are calling fun.cpp instead of fun.hpp. So c++ compiler finds func.cpp definition twice and throws this error.

Change line 3 of your main.cpp file, from #include "fun.cpp" to #include "fun.hpp" .

I think you will have to have 2 routes. If you look at line 331 of the connect router the * in a path is replaced with .+ so will match 1 or more characters.

https://github.com/senchalabs/connect/blob/master/lib/middleware/router.js

If you have 2 routes that perform the same action you can do the following to keep it DRY.

var express = require("express"),
    app = express.createServer();

function fooRoute(req, res, next) {
  res.end("Foo Route\n");
}

app.get("/foo*", fooRoute);
app.get("/foo", fooRoute);

app.listen(3000);

Those variables are shell variables. To expand them as parameters to another program (ie expr), you need to use the $ prefix:

expr $x / $y

The reason it complained is because it thought you were trying to operate on alphabetic characters (ie non-integer)

If you are using the Bash shell, you can achieve the same result using expression syntax:

echo $((x / y))

Or:

z=$((x / y))
echo $z

OPTION 1: if you want to make a common utility function then you can use this

export function getCurrentDate(separator=''){

let newDate = new Date()
let date = newDate.getDate();
let month = newDate.getMonth() + 1;
let year = newDate.getFullYear();

return `${year}${separator}${month<10?`0${month}`:`${month}`}${separator}${date}`
}

and use it by just importing it as

import {getCurrentDate} from './utils'
console.log(getCurrentDate())

OPTION 2: or define and use in a class directly

getCurrentDate(separator=''){

let newDate = new Date()
let date = newDate.getDate();
let month = newDate.getMonth() + 1;
let year = newDate.getFullYear();

return `${year}${separator}${month<10?`0${month}`:`${month}`}${separator}${date}`
}

bash will not give you correct result of 3/2 since it doesn't do floating pt maths. you can use tools like awk

$ awk  'BEGIN { rounded = sprintf("%.0f", 3/2); print rounded }'
2

or bc

$ printf "%.0f" $(echo "scale=2;3/2" | bc)
2

IMHO this is the best way to write your line :

private static final Map<Class<? extends Persistent>, PersistentHelper> class2helper =
        new HashMap<Class<? extends Persistent>, PersistentHelper>();

This way the increased indentation without any braces can help you to see that the code was just splited because the line was too long. And instead of 4 spaces, 8 will make it clearer.

Here are some examples from this blog mentioned earlier:

<configuration>    
   <Database>    
      <add key="ConnectionString" value="data source=.;initial catalog=NorthWind;integrated security=SSPI"/>    
   </Database>    
</configuration>  

get values:

 NameValueCollection db = (NameValueCollection)ConfigurationSettings.GetConfig("Database");         
    labelConnection2.Text = db["ConnectionString"];

-

Another example:

<Locations 
   ImportDirectory="C:\Import\Inbox"
   ProcessedDirectory ="C:\Import\Processed"
   RejectedDirectory ="C:\Import\Rejected"
/>

get value:

Hashtable loc = (Hashtable)ConfigurationSettings.GetConfig("Locations"); 

labelImport2.Text = loc["ImportDirectory"].ToString();
labelProcessed2.Text = loc["ProcessedDirectory"].ToString();

It should be fixed on server side. Your server should return this headers for this file types:

Content-Type: application/octet-stream
Content-Disposition: attachment;filename=\"filename.xxx\"

As of now (NOV-2019), graph.api V5.0

graph API says, refer graph api

A link to the person's Timeline. The link will only resolve if the person clicking the link is logged into Facebook and is a friend of the person whose profile is being viewed.

This should work:

override func viewDidLoad() {
    super.viewDidLoad()

    var button = UIBarButtonItem(title: "YourTitle", style: UIBarButtonItemStyle.Bordered, target: self, action: "goBack")
    self.navigationItem.backBarButtonItem = button

}

func goBack()
{
    self.navigationController?.popViewControllerAnimated(true)
}

Although it is not recommended since this actually replaces the backButton and it also removed the back arrow and the swipe gesture.

You can't extend Enum as it's a static class. You can only extend instances of a type. With this in mind, you're going to have to create a static method yourself to do this; the following should work when combined with your existing method GetDescription:

public static class EnumHelper
{
    public static T GetEnumFromString<T>(string value)
    {
        if (Enum.IsDefined(typeof(T), value))
        {
            return (T)Enum.Parse(typeof(T), value, true);
        }
        else
        {
            string[] enumNames = Enum.GetNames(typeof(T));
            foreach (string enumName in enumNames)
            {  
                object e = Enum.Parse(typeof(T), enumName);
                if (value == GetDescription((Enum)e))
                {
                    return (T)e;
                }
            }
        }
        throw new ArgumentException("The value '" + value 
            + "' does not match a valid enum name or description.");
    }
}

And the usage of it would be something like this:

Animal giantPanda = EnumHelper.GetEnumFromString<Animal>("Giant Panda");

Try it:

def showDf(df, count=None, percent=None, maxColumns=0):
    if (df == None): return
    import pandas
    from IPython.display import display
    pandas.set_option('display.encoding', 'UTF-8')
    # Pandas dataframe
    dfp = None
    # maxColumns param
    if (maxColumns >= 0):
        if (maxColumns == 0): maxColumns = len(df.columns)
        pandas.set_option('display.max_columns', maxColumns)
    # count param
    if (count == None and percent == None): count = 10 # Default count
    if (count != None):
        count = int(count)
        if (count == 0): count = df.count()
        pandas.set_option('display.max_rows', count)
        dfp = pandas.DataFrame(df.head(count), columns=df.columns)
        display(dfp)
    # percent param
    elif (percent != None):
        percent = float(percent)
        if (percent >=0.0 and percent <= 1.0):
            import datetime
            now = datetime.datetime.now()
            seed = long(now.strftime("%H%M%S"))
            dfs = df.sample(False, percent, seed)
            count = df.count()
            pandas.set_option('display.max_rows', count)
            dfp = dfs.toPandas()    
            display(dfp)

Examples of usages are:

# Shows the ten first rows of the Spark dataframe
showDf(df)
showDf(df, 10)
showDf(df, count=10)

# Shows a random sample which represents 15% of the Spark dataframe
showDf(df, percent=0.15) 

For me, fny answers really got it all. since fetch is not throwing error, we need to throw/handle the error ourselves. Posting my solution with async/await. I think it's more strait forward and readable

Solution 1: Not throwing an error, handle the error ourselves

  async _fetch(request) {
    const fetchResult = await fetch(request); //Making the req
    const result = await fetchResult.json(); // parsing the response

    if (fetchResult.ok) {
      return result; // return success object
    }


    const responseError = {
      type: 'Error',
      message: result.message || 'Something went wrong',
      data: result.data || '',
      code: result.code || '',
    };

    const error = new Error();
    error.info = responseError;

    return (error);
  }

Here if we getting an error, we are building an error object, plain JS object and returning it, the con is that we need to handle it outside. How to use:

  const userSaved = await apiCall(data); // calling fetch
  if (userSaved instanceof Error) {
    debug.log('Failed saving user', userSaved); // handle error

    return;
  }
  debug.log('Success saving user', userSaved); // handle success

Solution 2: Throwing an error, using try/catch

async _fetch(request) {
    const fetchResult = await fetch(request);
    const result = await fetchResult.json();

    if (fetchResult.ok) {
      return result;
    }

    const responseError = {
      type: 'Error',
      message: result.message || 'Something went wrong',
      data: result.data || '',
      code: result.code || '',
    };

    let error = new Error();
    error = { ...error, ...responseError };
    throw (error);
  }

Here we are throwing and error that we created, since Error ctor approve only string, Im creating the plain Error js object, and the use will be:

  try {
    const userSaved = await apiCall(data); // calling fetch
    debug.log('Success saving user', userSaved); // handle success
  } catch (e) {
    debug.log('Failed saving user', userSaved); // handle error
  }

Solution 3: Using customer error

  async _fetch(request) {
    const fetchResult = await fetch(request);
    const result = await fetchResult.json();

    if (fetchResult.ok) {
      return result;
    }

    throw new ClassError(result.message, result.data, result.code);
  }

And:

class ClassError extends Error {

  constructor(message = 'Something went wrong', data = '', code = '') {
    super();
    this.message = message;
    this.data = data;
    this.code = code;
  }

}

Hope it helped.

Here is the same style as in large datasets:

x = df[:5]
y = pd.DataFrame([['...']*df.shape[1]], columns=df.columns, index=['...'])
z = df[-5:]
frame = [x, y, z]
result = pd.concat(frame)

print(result)

Output:

                     date  temp
0     1981-01-01 00:00:00  20.7

I agree with the accepted answer. But for me, the issue was not that, instead I had to modify my Servlet-Class name from:-

<servlet-class>org.glassfish.jersey.servlet.ServletContainer.class</servlet-class> 

To:

<servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>

So, removing .class worked fine in my case. Hope it will help somebody!

Never fails, once I post the question to SO, I get some enlightening "aha" moment and figure it out. The solution:

    .container {_x000D_
       border: 1px solid #DDDDDD;_x000D_
       width: 200px;_x000D_
       height: 200px;_x000D_
       position: relative;_x000D_
    }_x000D_
    .tag {_x000D_
       float: left;_x000D_
       position: absolute;_x000D_
       left: 0px;_x000D_
       top: 0px;_x000D_
       z-index: 1000;_x000D_
       background-color: #92AD40;_x000D_
       padding: 5px;_x000D_
       color: #FFFFFF;_x000D_
       font-weight: bold;_x000D_
    }

<div class="container">_x000D_
       <div class="tag">Featured</div>_x000D_
       <img src="http://www.placehold.it/200x200">_x000D_
</div>

The key is the container has to be positioned relative and the tag positioned absolute.

At the answer from @squicc if you amend this line: $topDir = Get-ChildItem -directory "C:\test" with -force then you will be able to see the hidden directories also. Without this, the size will be different when you run the solution from inside or outside the folder.

The question does not mention the VM Provider but in my case, I use Virtual Box under the same environment. There is an option in the Virtual Box GUI that I needed to enable in order to make it work. Is located in the Virtual Box app preferences: File >> Preferences... >> Proxy. Once I configured this, I was able to work without problems. Hope this tip can also help you guys.

I think the reason the OPs code does not work is because once you call Remove you are changing the Length of drr. When you call Delete you are not actually deleting the row until AcceptChanges is called. This is why if you want to use Remove you need a separate loop.

Depending on the situation or preference...

string colName = "colName";
string comparisonValue = (whatever it is).ToString();
string strFilter = (dtbl.Columns[colName].DataType == typeof(string)) ? "[" + colName + "]='" + comparisonValue + "'" : "[" + colName + "]=" + comparisonValue;
string strSort = "";

DataRow[] drows = dtbl.Select(strFilter, strSort, DataViewRowState.CurrentRows);

Above used for next two examples

foreach(DataRow drow in drows)
{
   drow.Delete();//Mark a row for deletion.
}
dtbl.AcceptChanges();

OR

foreach(DataRow drow in drows)
{
   dtbl.Rows[dtbl.Rows.IndexOf(drow)].Delete();//Mark a row for deletion.
}
dtbl.AcceptChanges();

OR

List<DataRow> listRowsToDelete = new List<DataRow>();

foreach(DataRow drow in dtbl.Rows)
{
   if(condition to delete)
   {
      listRowsToDelete.Add(drow);
   }
}

foreach(DataRow drowToDelete in listRowsToDelete)
{
   dtbl.Rows.Remove(drowToDelete);// Calling Remove is the same as calling Delete and then calling AcceptChanges
}

Note that if you call Delete() then you should call AcceptChanges() but if you call Remove() then AcceptChanges() is not necessary.

Also, here is a good link on row filter syntax.

To add on NikiC's answer. const can be used within classes in the following manner:

class Foo {
    const BAR = 1;

    public function myMethod() {
        return self::BAR;
    }
}

You can not do this with define().

While you cannot prevent orientation change from taking effect you can emulate no change as stated in other answers.

First detect device orientation or reorientation and, using JavaScript, add a class name to your wrapping element (in this example I use the body tag).

function deviceOrientation() {
  var body = document.body;
  switch(window.orientation) {
    case 90:
      body.classList = '';
      body.classList.add('rotation90');
      break;
    case -90:
      body.classList = '';
      body.classList.add('rotation-90');
      break;
    default:
      body.classList = '';
      body.classList.add('portrait');
      break;
  }
}
window.addEventListener('orientationchange', deviceOrientation);
deviceOrientation();

Then if the device is landscape, use CSS to set the body width to the viewport height and the body height to the viewport width. And let’s set the transform origin while we’re at it.

@media screen and (orientation: landscape) {
  body {
    width: 100vh;
    height: 100vw;
    transform-origin: 0 0;
  }
}

Now, reorient the body element and slide (translate) it into position.

body.rotation-90 {
  transform: rotate(90deg) translateY(-100%);
}
body.rotation90 {
  transform: rotate(-90deg) translateX(-100%);
}

Use the .on() method with delegated events

$('#staticParent').on('click', '.dynamicElement', function() {
    // Do something on an existent or future .dynamicElement
});

The .on() method allows you to delegate any desired event handler to:
current elements or future elements added to the DOM at a later time.

_{P.S: Don't use .live()! From jQuery 1.7+ the .live() method is deprecated.}

As indicated in the online manual, the most common cause for that error is that lines are indented with spaces when make expects tab characters.

Correct

target: 
\tcmd

where \t is TAB (U+0009)

Wrong

target:
....cmd

where each . represents a SPACE (U+0020).

$query_ids = $this->getEntityManager()
      ->createQuery(
        "SELECT e_.id
        FROM MuzichCoreBundle:Element e_
        WHERE [...]
        GROUP BY e_.id")
     ->setMaxResults(5)
     ->setMaxResults($limit) 
    ;

HERE in the second query the result of the first query should be passed ..

$query_select = "SELECT e
      FROM MuzichCoreBundle:Element e 
      WHERE e.id IN (".$query_ids->getResult().")
      ORDER BY e.created DESC, e.name DESC"
    ;


$query = $this->getEntityManager()
      ->createQuery($query_select)
      ->setParameters($params)
      ->setMaxResults($limit);
    ;

$resultCollection = $query->getResult();

You should try it like this:

var result =
        from priceLog in PriceLogList
        group priceLog by priceLog.LogDateTime.ToString("MMM yyyy") into dateGroup
        select new {
            LogDateTime = dateGroup.Key,
            AvgPrice = dateGroup.Average(priceLog => priceLog.Price)
        };

Make a script

#!/bin/sh
echo $* 1>&2

that would be your tool.

Or make a function if you don't want to have a script in separate file.

COPY README.md package.json gulpfile.js __BUILD_NUMBER ./

or

COPY ["__BUILD_NUMBER", "README.md", "gulpfile", "another_file", "./"]

You can also use wildcard characters in the sourcefile specification. See the docs for a little more detail.

Directories are special! If you write

COPY dir1 dir2 ./

that actually works like

COPY dir1/* dir2/* ./

If you want to copy multiple directories (not their contents) under a destination directory in a single command, you'll need to set up the build context so that your source directories are under a common parent and then COPY that parent.

Try pass array to vector:

int arr[] = {2,5,8,11,14};
std::vector<int> TestVector(arr, arr+5);

You could always call std::vector::assign to assign array to vector, call std::vector::insert to add multiple arrays.

If you use C++11, you can try:

std::vector<int> v{2,5,8,11,14};

Or

 std::vector<int> v = {2,5,8,11,14};

DateTime doesn't have a format. the format only applies when you're turning a DateTime into a string, which happens implicitly you show the value on a form, web page, etc.

Look at where you're displaying the DateTime and set the format there (or amend your question if you need additional guidance).

This came across while working on a project on linux platform.

exec('wget http://<url to the php script>)

This runs as if you run the script from browser.

Hope this helps!!

Or you can decrement/increment a variable by the number of times you want to loop:

SETLOCAL ENABLEDELAYEDEXPANSION
SET counter=200
:Beginning
IF %counter% NEQ 0 (
echo %x
copy %x.txt z:\whatever\etc
SET /A counter=%counter%-1
GOTO Beginning
) ELSE (
ENDLOCAL
SET counter=
GOTO:eof

Obviously, using FOR /L is the highway and this is the backstreet that takes longer, but it gets to the same destination.

One way I can imagine is to use a linked list to implement such a scenario, if you need all the numbers entered before the user enters something which indicates the loop termination. (posting as the first option, because have never done this for user input, it just seemed to be interesting. Wasteful but artistic)

Another way is to do buffered input. Allocate a buffer, fill it, re-allocate, if the loop continues (not elegant, but the most rational for the given use-case).

I don't consider the described to be elegant though. Probably, I would change the use-case (the most rational).

I had this situation restoring a database to an SQL Server 2005 Standard Edition instance using Symantec Backup Exec 11d. After the restore job completed the database remained in a "Restoring" state. I had no disk space issues-- the database simply didn't come out of the "Restoring" state.

I ran the following query against the SQL Server instance and found that the database immediately became usable:

RESTORE DATABASE <database name> WITH RECOVERY

If the indices match then:

df['B'] = df1['E']

should work otherwise:

df['B'] = df1['E'].values

will work so long as the length of the elements matches

I have tried many include sudo apt-get purge ruby , sudo apt-get remove ruby and sudo aptitude purpe ruby, both with and without '*' at the end. But none of them worked, it's may be I've installed more than one version ruby.

Finally, when I triedsudo apt-get purge ruby1.9(with the version), then it works.

Two ways to implement a Caesar Cipher:

Option 1: Change chars to ASCII numbers, then you can increase the value, then revert it back to the new character.

Option 2: Use a Map map each letter to a digit like this.

A - 0
B - 1
C - 2
etc...

With a map you don't have to re-calculate the shift every time. Then you can change to and from plaintext to encrypted by following map.

As I see it there are really three choices here and the solution depends on the context. You can choose to implement the construction of the name in the method that produces the list. This is the choice you've chosen, but I don't think it is the best one. You are creating a coupling in the producer method to the consuming method that doesn't need to exist. Other callers may not need the extra information and you would be calculating extra information for these callers.

Alternatively, you could have the calling method calculate the name. If there is only one caller that needs this information, you can stop there. You have no extra dependencies and while there is a little extra calculation involved, you've avoided making your construction method too specific. This is a good trade-off.

Lastly, you could have the list itself be responsible for creating the name. This is the route I would go if the calculation needs to be done by more than one caller. I think this puts the responsibility for the creation of the names with the class that is most closely related to the objects themselves.

In the latter case, my solution would be to create a specialized List class that returns a comma-separated string of the names of objects that it contains. Make the class smart enough that it constructs the name string on the fly as objects are added and removed from it. Then return an instance of this list and call the name generation method as needed. Although it may be almost as efficient (and simpler) to simply delay calculation of the names until the first time the method is called and store it then (lazy loading). If you add/remove an object, you need only remove the calculated value and have it get recalculated on the next call.

1NF: Only one value per column

2NF: All the non primary key columns in the table should depend on the entire primary key.

3NF: All the non primary key columns in the table should depend DIRECTLY on the entire primary key.

I have written an article in more detail over here

technically, the answer is NO it is not possible to delete two objects AT THE SAME TIME. However, it IS possible to delete two objects in one line of beautiful python.

del (foo['bar'],foo['baz'])

will recusrively delete foo['bar'], then foo['baz']

I was looking for the same and ended up by creating a static method inside a Helper class (in my case I named it App\Helpers\Database).

The method

/**
 * Method to get the autoincrement value from a database table
 *
 * @access public
 *
 * @param string $database The database name or configuration in the .env file
 * @param string $table    The table name
 *
 * @return mixed
 */
public static function getAutoIncrementValue($database, $table)
{
    $database ?? env('DB_DATABASE');

    return \DB::select("
        SELECT AUTO_INCREMENT 
        FROM information_schema.TABLES 
        WHERE TABLE_SCHEMA = '" . env('DB_DATABASE') . "' 
        AND TABLE_NAME = '" . $table . "'"
    )[0]->AUTO_INCREMENT;
}

To call the method and get the MySql AUTO_INCREMENT just use the following:

$auto_increment = \App\Helpers\Database::getAutoIncrementValue(env('DB_DATABASE'), 'your_table_name');

Hope it helps.

The solution I have come up with is that you can use download attribute in anchor tag but it will only work if your html file is on the server. but you may have a question like while designing a simple html page how can we check that for that you can use VS code live server or bracket live server and you will see your download attribute will work but if you will try to open it simply by just double clicking html page it open the file instead of downloading it. conclusion: attribute download in anchor tag only works if your html file is no server.

What about injecting the class attribute after the class definition?

class Klass(object):

    @staticmethod  # use as decorator
    def stat_func():
        return 42

    def method(self):
        ret = Klass.stat_func()
        return ret

Klass._ANS = Klass.stat_func()  # inject the class attribute with static method value

ElasticSearch itself provides a way to create data backup and restoration. The simple command to do it is:

CURL -XPUT 'localhost:9200/_snapshot/<backup_folder name>/<backupname>' -d '{
    "indices": "<index_name>",
    "ignore_unavailable": true,
    "include_global_state": false
}'

Now, how to create, this folder, how to include this folder path in ElasticSearch configuration, so that it will be available for ElasticSearch, restoration method, is well explained here. To see its practical demo surf here.

Simply call your Action Method by using Javascript as shown below:

var id = model.Id; //if you want to pass an Id parameter
window.location.href = '@Url.Action("Action", "Controller")/' + id;

Hope this helps...

Had a similar problem when starting apache jmeter on windows 8 64 bit:

[]apache-jmeter-2.13\bin>jmeter
java.util.prefs.WindowsPreferences <init>
WARNING: Could not open/create prefs root node Software\JavaSoft\Prefs     at root 0x80000002. Windows RegCreateKeyEx(...) returned error code 5.

Successfully used Dennis Traub solution, with Mkorsch explanations. Or you can create a file with the extension "reg" and write into it the following:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Prefs]

... then execute it.

It seems as though gradle was not installed for me. Going to Android/Sdk/tools/templates/gradle/wrapper and running ./gradlew tasks --debug has resulted in it downloading.

Well, the "text-overflow: ellipsis" worked for me, but just if my limit was based on 'width', I has needed a solution that can be applied on lines ( on the'height' instead the 'width' ) so I did this script:

function listLimit (elm, line){
    var maxHeight = parseInt(elm.css('line-Height'))*line;

    while(elm.height() > maxHeight){
        var text = elm.text();
        elm.text(text.substring(0,text.length-10)).text(elm.text()+'...');
    }
}

And when I must, for example, that my h3 has only 2 lines I do :

$('h3').each(function(){
   listLimit ($(this), 2)
})

I dunno if that was the best practice for performance needs, but worked for me.

https://gist.github.com/db0company/369bfa43cb84b145dfd8 I did some tests on the answers and comments on this site. For me, the following works

extension UIViewController {
    func topMostViewController() -> UIViewController {

        if let presented = self.presentedViewController {
            return presented.topMostViewController()
        }

        if let navigation = self as? UINavigationController {
            return navigation.visibleViewController?.topMostViewController() ?? navigation
        }

        if let tab = self as? UITabBarController {
            return tab.selectedViewController?.topMostViewController() ?? tab
    }

        return self
    }
}

extension UIApplication {
    func topMostViewController() -> UIViewController? {
        return self.keyWindow?.rootViewController?.topMostViewController()
    }
}

Then, get the top viewController by:

UIApplication.shared.topMostViewController()

I have seen something similar before when the account the SQL Server is set to run under does not have the required permission.

Tangentially, once it is installed, a common mistake is to change the login credentials from Windows Services, not from SQL Server Configuration Manager. Although they look the same, the SQL Server tool grants access to some registry keys that the Windows tool does not, which can cause a problem on service startup.

You can run Sysinternals RegMon/Sysinternals ProcessMon while the install is running, filtering by sqlsevr.exe and Failure messages to see if the account credentials are a problem.

Hope this helps

Steps for Using Group by,Having By and Order by...

Select Attitude ,count(*) from Person
group by person
HAving PersonAttitude='cool and friendly'
Order by PersonName.

This works for me every time:

    if(!driver.findElements(By.xpath("//*[@id='submit']")).isEmpty()){
        //THEN CLICK ON THE SUBMIT BUTTON
    }else{
        //DO SOMETHING ELSE AS SUBMIT BUTTON IS NOT THERE
    }

Specify the name of columns in the CSV in the load data infile statement.

The code is like this:

LOAD DATA INFILE '/path/filename.csv'
INTO TABLE table_name
FIELDS TERMINATED BY ','
LINES TERMINATED BY '\r\n'
(column_name3, column_name5);

Here you go with adding data to only two columns(you can choose them with the name of the column) to the table.

The only thing you have to take care is that you have a CSV file(filename.csv) with two values per line(row). Otherwise please mention. I have a different solution.

Thank you.

With the inspiration from Roy Tinker's comment, I ended up using a simple extension method on the Uri class that keeps my code concise and clean:

using System.Web;

public static class HttpExtensions
{
    public static Uri AddQuery(this Uri uri, string name, string value)
    {
        var httpValueCollection = HttpUtility.ParseQueryString(uri.Query);

        httpValueCollection.Remove(name);
        httpValueCollection.Add(name, value);

        var ub = new UriBuilder(uri);
        ub.Query = httpValueCollection.ToString();

        return ub.Uri;
    }
}

Usage:

Uri url = new Uri("http://localhost/rest/something/browse").
          AddQuery("page", "0").
          AddQuery("pageSize", "200");

Edit - Standards compliant variant

As several people pointed out, httpValueCollection.ToString() encodes Unicode characters in a non-standards-compliant way. This is a variant of the same extension method that handles such characters by invoking HttpUtility.UrlEncode method instead of the deprecated HttpUtility.UrlEncodeUnicode method.

using System.Web;

public static Uri AddQuery(this Uri uri, string name, string value)
{
    var httpValueCollection = HttpUtility.ParseQueryString(uri.Query);

    httpValueCollection.Remove(name);
    httpValueCollection.Add(name, value);

    var ub = new UriBuilder(uri);

    // this code block is taken from httpValueCollection.ToString() method
    // and modified so it encodes strings with HttpUtility.UrlEncode
    if (httpValueCollection.Count == 0)
        ub.Query = String.Empty;
    else
    {
        var sb = new StringBuilder();

        for (int i = 0; i < httpValueCollection.Count; i++)
        {
            string text = httpValueCollection.GetKey(i);
            {
                text = HttpUtility.UrlEncode(text);

                string val = (text != null) ? (text + "=") : string.Empty;
                string[] vals = httpValueCollection.GetValues(i);

                if (sb.Length > 0)
                    sb.Append('&');

                if (vals == null || vals.Length == 0)
                    sb.Append(val);
                else
                {
                    if (vals.Length == 1)
                    {
                        sb.Append(val);
                        sb.Append(HttpUtility.UrlEncode(vals[0]));
                    }
                    else
                    {
                        for (int j = 0; j < vals.Length; j++)
                        {
                            if (j > 0)
                                sb.Append('&');

                            sb.Append(val);
                            sb.Append(HttpUtility.UrlEncode(vals[j]));
                        }
                    }
                }
            }
        }

        ub.Query = sb.ToString();
    }

    return ub.Uri;
}

Promises don't "return" values, they pass them to a callback (which you supply with .then()).

It's probably trying to say that you're supposed to do resolve(someObject); inside the promise implementation.

Then in your then code you can reference someObject to do what you want.

I made some changes for backspace

        string pass = "";
        Console.Write("Enter your password: ");
        ConsoleKeyInfo key;

        do
        {
            key = Console.ReadKey(true);

            // Backspace Should Not Work
            if (key.Key != ConsoleKey.Backspace)
            {
                pass += key.KeyChar;
                Console.Write("*");
            }
            else
            {
                pass = pass.Remove(pass.Length - 1);
                Console.Write("\b \b");
            }
        }
        // Stops Receving Keys Once Enter is Pressed
        while (key.Key != ConsoleKey.Enter);

        Console.WriteLine();
        Console.WriteLine("The Password You entered is : " + pass);

In addition to Marty's excellent Answer, the SystemVerilog specification offers the byte data type. The following declares a 4x8-bit variable (4 bytes), assigns each byte a value, then displays all values:

module tb;

byte b [4];

initial begin
    foreach (b[i]) b[i] = 1 << i;
    foreach (b[i]) $display("Address = %0d, Data = %b", i, b[i]);
    $finish;
end

endmodule

This prints out:

Address = 0, Data = 00000001
Address = 1, Data = 00000010
Address = 2, Data = 00000100
Address = 3, Data = 00001000

This is similar in concept to Marty's reg [7:0] a [0:3];. However, byte is a 2-state data type (0 and 1), but reg is 4-state (01xz). Using byte also requires your tool chain (simulator, synthesizer, etc.) to support this SystemVerilog syntax. Note also the more compact foreach (b[i]) loop syntax.

The SystemVerilog specification supports a wide variety of multi-dimensional array types. The LRM can explain them better than I can; refer to IEEE Std 1800-2005, chapter 5.

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

The first argument is the file you wish to execute, and the second argument is an array of null-terminated strings that represent the appropriate arguments to the file as specified in the man page.

For example:

char *cmd = "ls";
char *argv[3];
argv[0] = "ls";
argv[1] = "-la";
argv[2] = NULL;

execvp(cmd, argv); //This will run "ls -la" as if it were a command

In my case, my maven variable environment was M2_HOME, so I've changed to MAVEN_HOME and worked.

Make sure you have not committed a typo as in my case

msyql_fetch_assoc should be mysql

In Chrome, go to options (Customize and Control, the 3 dots/bars at top right) ---> More Tools ---> save page as

save page as  
filename     : any_name.html 
save as type : webpage complete.

Then you will get any_name.html and any_name folder.

Use ObjectDataProvider:

<ObjectDataProvider x:Key="enumValues"
   MethodName="GetValues" ObjectType="{x:Type System:Enum}">
      <ObjectDataProvider.MethodParameters>
           <x:Type TypeName="local:ExampleEnum"/>
      </ObjectDataProvider.MethodParameters>
 </ObjectDataProvider>

and then bind to static resource:

ItemsSource="{Binding Source={StaticResource enumValues}}"

1. clang has advantages in error reporting & recovery.

   $ clang errors.c
   errors.c:36:21: warning: result of comparison against a string literal is unspecified (use strcmp instead)
           if (args[i] == "&") //WARNING HERE
                       ^~ ~~~
               strcmp( ,     ) == 0
   errors.c:38:26: warning: result of comparison against a string literal is unspecified (use strcmp instead)
           else if (args[i] == "<") //WARNING HERE
                            ^~ ~~~
                    strcmp( ,     ) == 0
   errors.c:44:26: warning: result of comparison against a string literal is unspecified (use strcmp instead)
           else if (args[i] == ">") //WARNING HERE

                    strcmp( ,     ) == 0
   

   It suggests to replace x == y by strcmp(x,y) == 0.

2. gengetopt writes command-line option parser for you.

For a number between 0 and 100.

Number.parseInt(Math.floor(Math.random() * 100))

For a lot of utility-type methods, the apache commons libraries have solid implementations that you can either leverage or get additional insight from. In this case, there is a method for finding the smallest of three doubles available in org.apache.commons.lang.math.NumberUtils. Their implementation is actually nearly identical to your initial thought:

public static double min(double a, double b, double c) {
    return Math.min(Math.min(a, b), c);
}

I recommend following the instructions in the Bootstrap 4 documentation:

Copy-paste the stylesheet <link> into your <head> before all other stylesheets to load our CSS.

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/4.0.0-alpha.6/css/bootstrap.min.css" integrity="sha384-rwoIResjU2yc3z8GV/NPeZWAv56rSmLldC3R/AZzGRnGxQQKnKkoFVhFQhNUwEyJ" crossorigin="anonymous">

Add our JavaScript plugins, jQuery, and Tether near the end of your pages, right before the closing tag. Be sure to place jQuery and Tether first, as our code depends on them. While we use jQuery’s slim build in our docs, the full version is also supported.

<script src="https://code.jquery.com/jquery-3.1.1.slim.min.js" integrity="sha384-A7FZj7v+d/sdmMqp/nOQwliLvUsJfDHW+k9Omg/a/EheAdgtzNs3hpfag6Ed950n" crossorigin="anonymous"></script>

This answer uses promises, a JavaScript feature of the ECMAScript 6 standard. If your target platform does not support promises, polyfill it with PromiseJs.

Promises are a new (and a lot better) way to handle asynchronous operations in JavaScript:

$('a.button').click(function(){
    if (condition == 'true'){
        function1(someVariable).then(function() {
            //this function is executed after function1
            function2(someOtherVariable);
        });
    }
    else {
        doThis(someVariable);
    }
});


function function1(param, callback) {
    return new Promise(function (fulfill, reject){
        //do stuff
        fulfill(result); //if the action succeeded
        reject(error); //if the action did not succeed
    });
} 

This may seem like a significant overhead for this simple example, but for more complex code it is far better than using callbacks. You can easily chain multiple asynchronous calls using multiple then statements:

function1(someVariable).then(function() {
    function2(someOtherVariable);
}).then(function() {
    function3();
});

You can also wrap jQuery deferrds easily (which are returned from $.ajax calls):

Promise.resolve($.ajax(...params...)).then(function(result) {
    //whatever you want to do after the request
});

As @charlietfl noted, the jqXHR object returned by $.ajax() implements the Promise interface. So it is not actually necessary to wrap it in a Promise, it can be used directly:

$.ajax(...params...).then(function(result) {
    //whatever you want to do after the request
});

Vincent Povirk's answer won't work completely;

import zipfile
archive = zipfile.ZipFile('images.zip', 'r')
imgfile = archive.open('img_01.png')
...

You have to change it in:

import zipfile
archive = zipfile.ZipFile('images.zip', 'r')
imgdata = archive.read('img_01.png')
...

For details read the ZipFile docs here.

One of the difference is Null termination (\0).

In C and C++, char* or char[] will take a pointer to a single char as a parameter and will track along the memory until a 0 memory value is reached (often called the null terminator).

C++ strings can contain embedded \0 characters, know their length without counting.

#include<stdio.h>
#include<string.h>
#include<iostream>

using namespace std;

void NullTerminatedString(string str){
   int NUll_term = 3;
   str[NUll_term] = '\0';       // specific character is kept as NULL in string
   cout << str << endl <<endl <<endl;
}

void NullTerminatedChar(char *str){
   int NUll_term = 3;
   str[NUll_term] = 0;     // from specific, all the character are removed 
   cout << str << endl;
}

int main(){
  string str = "Feels Happy";
  printf("string = %s\n", str.c_str());
  printf("strlen = %d\n", strlen(str.c_str()));  
  printf("size = %d\n", str.size());  
  printf("sizeof = %d\n", sizeof(str)); // sizeof std::string class  and compiler dependent
  NullTerminatedString(str);


  char str1[12] = "Feels Happy";
  printf("char[] = %s\n", str1);
  printf("strlen = %d\n", strlen(str1));
  printf("sizeof = %d\n", sizeof(str1));    // sizeof char array
  NullTerminatedChar(str1);
  return 0;
}

Output:

strlen = 11
size = 11
sizeof = 32  
Fee s Happy


strlen = 11
sizeof = 12
Fee

I have used Fredrik's code above in a project with some slight modifications, thought I'd share:

private static bool DownloadRemoteImageFile(string uri, string fileName)
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri);
    HttpWebResponse response;
    try
    {
        response = (HttpWebResponse)request.GetResponse();
    }
    catch (Exception)
    {
        return false;
    }

    // Check that the remote file was found. The ContentType
    // check is performed since a request for a non-existent
    // image file might be redirected to a 404-page, which would
    // yield the StatusCode "OK", even though the image was not
    // found.
    if ((response.StatusCode == HttpStatusCode.OK ||
        response.StatusCode == HttpStatusCode.Moved ||
        response.StatusCode == HttpStatusCode.Redirect) &&
        response.ContentType.StartsWith("image", StringComparison.OrdinalIgnoreCase))
    {

        // if the remote file was found, download it
        using (Stream inputStream = response.GetResponseStream())
        using (Stream outputStream = File.OpenWrite(fileName))
        {
            byte[] buffer = new byte[4096];
            int bytesRead;
            do
            {
                bytesRead = inputStream.Read(buffer, 0, buffer.Length);
                outputStream.Write(buffer, 0, bytesRead);
            } while (bytesRead != 0);
        }
        return true;
    }
    else
        return false;
}

Main changes are:

• using a try/catch for the GetResponse() as I was running into an exception when the remote file returned 404
• returning a boolean

If someone wants to try a slightly different approach, they can use FLEX.

HTML

<div class="test">
    <div>Div 1</div>
    <div>Div 2</div>
    <div>Div 3</div>
    <div>Div 4</div>
</div>

CSS

.test {
    display: flex;
    flex-flow: row wrap;
    justify-content: space-around;
}
.test > div {
    margin-top: 10px;
    padding: 20px;
    background-color: #FF0000;
}

Here is the fiddle: http://jsfiddle.net/ynemh3c2/ (Try adding/removing divs as well)

Here is where I learned about this: https://css-tricks.com/snippets/css/a-guide-to-flexbox/

This should work for matches that might overlap:

public static void main(String[] args) {
    String input = "aaaaaaaa";
    String regex = "aa";
    Pattern pattern = Pattern.compile(regex);
    Matcher matcher = pattern.matcher(input);
    int from = 0;
    int count = 0;
    while(matcher.find(from)) {
        count++;
        from = matcher.start() + 1;
    }
    System.out.println(count);
}

if you face this problem to type in your git bash

git config --global user.name yourname

git config --global user.email youremail

if problem this cmds please try those cmds vica versa

Upgrading mod_php with Apache

This section describes the upgrade process for a system using Apache as the web server and mod_php to execute PHP code. If, instead, you are running Nginx and PHP-FPM, skip ahead to the next section.

Begin by removing existing PHP packages. Press y and hit Enter to continue when prompted.

sudo yum remove php-cli mod_php php-common

Install the new PHP 7 packages from IUS. Again, press y and Enter when prompted.

sudo yum install mod_php70u php70u-cli php70u-mysqlnd

Finally, restart Apache to load the new version of mod_php:

sudo apachectl restart

You can check on the status of Apache, which is managed by the httpd systemd unit, using systemctl:

systemctl status httpd

Even when they say that all services and factories are singleton, I don't agree 100 percent with that. I would say that factories are not singletons and this is the point of my answer. I would really think about the name that defines every component(Service/Factory), I mean:

A factory because is not a singleton, you can create as many as you want when you inject, so it works like a factory of objects. You can create a factory of an entity of your domain and work more comfortably with this objects which could be like an object of your model. When you retrieve several objects you can map them in this objects and it can act kind of another layer between the DDBB and the AngularJs model.You can add methods to the objects so you oriented to objects a little bit more your AngularJs App.

Meanwhile a service is a singleton, so we can only create 1 of a kind, maybe not create but we have only 1 instance when we inject in a controller, so a service provides more like a common service(rest calls,functionality.. ) to the controllers.

Conceptually you can think like services provide a service, factories can create multiple instances(objects) of a class

This answer aims to force an image pull in a situation where your node has already downloaded an image with the same name, therefore even though you push a new image to container registry, when you spin up some pods, your pod says "image already present".

For a case in Azure Container Registry (probably AWS and GCP also provides this):

1. You can look to your Azure Container Registry and by checking the manifest creation date you can identify what image is the most recent one.

2. Then, copy its digest hash (which has a format of sha256:xxx...xxx).

3. You can scale down your current replica by running command below. Note that this will obviously stop your container and cause downtime.

kubectl scale --replicas=0 deployment <deployment-name> -n <namespace-name>

4. Then you can get the copy of the deployment.yaml by running:

kubectl get deployments.apps <deployment-name> -o yaml > deployment.yaml

5. Then change the line with image field from <image-name>:<tag> to <image-name>@sha256:xxx...xxx, save the file.

6. Now you can scale up your replicas again. New image will be pulled with its unique digest.

Note: It is assumed that, imagePullPolicy: Always field is present in the container.

What worked for me is:

GoTo

setting.gradle

1. change the name in it.
2. go to the app root folder which you want to change and refactor--> rename it.
3. close the android studio.
4. browse to the folder and change the name
5. start android studio again.
6. do the gradle sync.

And you are done!

You could use the random.sample function from the standard library to select k elements from a population:

import random
random.sample(range(low, high), n)

In case of a rather large range of possible numbers, you could use itertools.islice with an infinite random generator:

import itertools
import random

def random_gen(low, high):
    while True:
        yield random.randrange(low, high)

gen = random_gen(1, 100)
items = list(itertools.islice(gen, 10))  # Take first 10 random elements

After the question update it is now clear that you need n distinct (unique) numbers.

import itertools
import random

def random_gen(low, high):
    while True:
        yield random.randrange(low, high)

gen = random_gen(1, 100)

items = set()

# Try to add elem to set until set length is less than 10
for x in itertools.takewhile(lambda x: len(items) < 10, gen):
    items.add(x)

With props to Rick (second comment down in the blog post mentioned), here's the MSDN article on httpOnlyCookies.

Bottom line is that you just add the following section in your system.web section in your web.config:

<httpCookies domain="" httpOnlyCookies="true|false" requireSSL="true|false" />

Try adding the header file to your project's files. (right click on project -> add existing file).

The most flexible way to do this:

#content::after {
  display:block;
  content:"";
  clear:both;
}

This acts exactly the same as appending the element to #content:

<br style="clear:both;"/>

but without actually adding an element. ::after is called a pseudo element. The only reason this is better than adding overflow:hidden; to #content is that you can have absolute positioned child elements overflow and still be visible. Also it will allow box-shadow's to still be visible.

Github did this using the HTML canvas element.

This specification defines the 2D Context for the HTML canvas element. The 2D Context provides objects, methods, and properties to draw and manipulate graphics on a canvas drawing surface.

If you use a browser inspector, you see inside every list element a div with a canvas element.

<div class="participation-graph">
   <canvas class="bars" data-color-all="#F5F5F5" data-color-owner="#F5F5F5" data-source="/mxcl/homebrew/graphs/owner_participation" height="80" width="640"></canvas>
</div>

With CSS (z-index, position...) you can put that canvas in the background of a li element or table, in your case.

Do a search about jquery pluggins that fit your requirement.

Hope this pointers help you to achieve that.

If you have access to a linux box with mdbtools installed, you can use this Bash shell script (save as mdbconvert.sh):

#!/bin/bash

TABLES=$(mdb-tables -1 $1)

MUSER="root"
MPASS="yourpassword"
MDB="$2"

MYSQL=$(which mysql)

for t in $TABLES
do
    $MYSQL -u $MUSER -p$MPASS $MDB -e "DROP TABLE IF EXISTS $t"
done

mdb-schema $1 mysql | $MYSQL -u $MUSER -p$MPASS $MDB

for t in $TABLES
do
    mdb-export -D '%Y-%m-%d %H:%M:%S' -I mysql $1 $t | $MYSQL -u $MUSER -p$MPASS $MDB
done

To invoke it simply call it like this:

./mdbconvert.sh accessfile.mdb mysqldatabasename

It will import all tables and all data.

You can also put the tooltip onto one line by removing the "title":

this.chart = new Chart(ctx, {
    type: this.props.horizontal ? 'horizontalBar' : 'bar',
    options: {
        legend: {
            display: false,
        },
        tooltips: {
            callbacks: {
                label: tooltipItem => `${tooltipItem.yLabel}: ${tooltipItem.xLabel}`, 
                title: () => null,
            }
        },
    },
});

The Authenticity Token is rails' method to prevent 'cross-site request forgery (CSRF or XSRF) attacks'.

To put it simple, it makes sure that the PUT / POST / DELETE (methods that can modify content) requests to your web app are made from the client's browser and not from a third party (an attacker) that has access to a cookie created on the client side.

Tried a combination of some answers and this eventually worked:

sudo -H pip install --upgrade --ignore-installed awsebcli

You can do something like this to check if any mysql process is running or not:

ps aux | grep mysqld
ps aux | grep mysql

Then if it is running you can killall by using(depending on what all processes are running currently):

killall -9 mysql
killall -9 mysqld
killall -9 mysqld_safe    

option 2 is a bad idea. It will result in something called shadowing; Basically you have two different "MyInt" members, one in the mother, and the other in the daughter. The problem with this, is that methods that are implemented in the mother will reference the mother's "MyInt" while methods implemented in the daughter will reference the daughter's "MyInt". this can cause some serious readability issues, and confusion later down the line.

Personally, I think the best option is 3; because it provides a clear centralized value, and can be referenced internally by children without the hassle of defining their own fields -- which is the problem with option 1.

You can create a much cleaner implementation with Moment.js Durations. No manual parsing necessary.

date.subtract(time);_x000D_
$('#MomentRocks').text(date.format())

As seen in this Angular example, there is a way to disable a button until the whole form is valid:

<button type="submit" [disabled]="!ngForm.valid">Submit</button>

I recently needed to do this and I came up with this

-- GROUP_CONCAT turns all the rows into 1
-- @q:= stores all the kill commands to a variable
select @q:=GROUP_CONCAT(CONCAT('KILL ',ID) SEPARATOR ';')  
FROM information_schema.processlist 
-- If you don't need it, you can remove the WHERE command altogether
WHERE user = 'user';
-- Creates statement and execute it
PREPARE stmt FROM @q;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;

That way, you don't need to store to file and run all queries with a single command.

The Ruby File class will give you the ins and outs of ::new and ::open but its parent, the IO class, gets into the depth of #read and #write.

If you want to use those with columns in another work with col-* classes, you can use order-* classes.

You can control the order of your columns with order classes. see more in Bootstrap 4 documentation

A simple from bootstrap docs:

<div class="container">
  <div class="row">
    <div class="col">
      First, but unordered
    </div>
    <div class="col order-12">
      Second, but last
    </div>
    <div class="col order-1">
      Third, but first
    </div>
  </div>
</div>

In my case problem was in using PowerShell instead of CMD :)

Since no one mentioned this, here's another way:

$date = date_create_from_format("m-d-Y", "10-16-2003")->format("Y-m-d");

One minor difference is what they convert of undefined or null,

Number() Or Number(null) // returns 0

while

parseInt() Or parseInt(null) // returns NaN

Style property can be used For HTML5 if you want to remove the boder of your frame or anything you can use the style property. as given below

Code goes here

<iframe src="demo.htm" style="border:none;"></iframe>

What you are looking for is called a Kalman Filter. It's frequently used to smooth navigational data. It is not necessarily trivial, and there is a lot of tuning you can do, but it is a very standard approach and works well. There is a KFilter library available which is a C++ implementation.

My next fallback would be least squares fit. A Kalman filter will smooth the data taking velocities into account, whereas a least squares fit approach will just use positional information. Still, it is definitely simpler to implement and understand. It looks like the GNU Scientific Library may have an implementation of this.

Package works fine on Friday, check in to TFS and go home. Open it on Monday, getting errors everywhere. "connection manager variable $project._connectionstring was not found in the variables collection".

I rtclick-edit the connection and test connectivity, works no prob;em. The ConnMnger is in the Connection Managers list in the solution. When open the TARGET object connected to this connection manager, and click on MAPPINGS, the error above pops up. There is no reference to connection manager variables anywhere in the mapping.

Turns out, to correct this you must right click on the connection manager in the Connection Manager window and choose PARAMETERIZE. Fill in the options as necessar -

PROPERTY: ConnectionString Use Exisgint Parameter: $Project::ConnMgrName_ConnectionString OR Create New PArameter: follow the options

Once this connection manager is parameterized, everything works. Even though the Conn Manger existed in the Conn Manger tab, the Conn Mgr is already listed in the Solution Explorer AND worked no problem 2 days prior.

Odd. Whatever. Microsoft being Microsoft. SQL Server being SQL Server. Choose your poison.

Hope this helps the next person save some time.

pip3 not pip. You can create an alias like you did with python3 if you like.

Here is a jQuery solution that I'm using.

jQuery

$("#slideshow button").click(function(){
    var val = $(this).val();
    console.log(val);
});

HTML

<div id="slideshow">
    <img src="image1.jpg">
    <button class="left" value="back">&#10094;</button>
    <button class="right" value="next">&#10095;</button>
</div>
